This problem originated in the work of Cohen on food webs. We consider it for the class of loopless symmetric digraphs. The competition graph of a symmetric digraph D is the two-step graph of the underlying graph H of D, denoted S-2(H). The two-step graph is also known as the neighborhood graph, and has been studied recently by Brigham and Dutton and by Boland, Brigham and Dutton. This work was motivated by a paper of Raychaudhuri and Roberts where they investigated symmetric digraphs with a loop at each vertex. Under these assumptions, the competition graph is the square of the underlying graph H without loops. Here we first consider forbidden subgraph characterizations of graphs with interval two-step graphs. Second, we characterize a large class of graphs with interval two-step graphs using the Gilmore-Hoffman characterization of interval graphs. C1 UNIV COLORADO, BOULDER, CO 80309 USA.

The latter sort of characterization is of interest when a competition graph that is easily colorable would be useful, e.g. in a scheduling or assignment problem. This leads naturally to the following question: Given a graph G, does the structure of G tell us anything about the chromatic number chi of the competition graph C(G)? We show that in some cases we can calculate this chromatic number exactly, while in others we can place tight bounds on it. C1 USN,POSTGRAD SCH,DEPT MATH,MONTEREY,CA 93943.

It discusses the Advanced Research Projects Agency (ARPA) MARITECH program and the application of technology for the U.S. shipbuilding industry to achieve international commercial competitiveness. For the DoD, a commercially competitive shipbuilding industry will optimize Navy ship acquisition reform and facilitate the department's objective for affordable Navy ships. The goal of the DoD Acquisition Reform program is to take advantage of the best commercial practices of industry and thereby achieve cost reductions of the systems it purchases. The government's attempts at acquisition reform as it applies to ship acquisition could fall short, however, if U.S. shipyards are not commercially competitive. Having operated exclusively in a protected domestic market, the U.S. shipbuilding industry has not implemented the best commercial processes necessary to compete in the international arena. To help the U.S. shipbuilding industry achieve internationally competitive commercial status, ARPA has implemented an integrated two-part technology program called MARITECH. The first part is application of existing technologies to help shipyards enter the international commercial shipbuilding market in the near term, while the second part seeks advanced technologies to get us ahead as well as keep us ahead of the competition. Technologies will be applied to all aspects of shipbuilding-marketing product development, detail design and planning, construction, guarantee, and follow-on support If MARITECH is successful, there will be an improved U.S. shipbuilding industry-one that is internationally competitive. By being internationally competitive, the government will be abbe to optimally reap the benefit of Navy ship acquisition reform-affordable Navy ships. C1 PRC INC,ARLINGTON,VA.

The interaction parameters are evaluated from the Wagner interaction parameters in ternary iron alloys reported in the literature or estimated from the interaction parameters in binary alloys. Two equilibrium conditions, para- and orthoequilibrium, are utilized. In the Fe-C-Mn-Si system, a mixed state of equilibrium, in which orthoequilibrium is achieved with respect to C and Si while the other two substitutional elements (Fe and Mn) are assumed to be immobile (paraequilibrium), is also considered. The calculated phase boundaries are employed to evaluate the free energy change for the nucleation and the growth kinetics of proeutectoid ferrite in these alloys in companion articles.

The results were compared with the predictions of the classical nucleation theory, using the pillbox-shaped critical nucleus model. The volume free energy changes associated with nucleation in Fe-C-X(1)-X(2) quaternary systems were evaluated from the central atoms model (CAM) for both para- and orthoequilibrium modes of transformation. The nucleation process was assumed to be controlled by volume and/or grain boundary diffusion of alloying elements. The so-called synergistic effects of alloying elements were considered in terms of the volume free energy change and interfacial energies on the basis of the results of the nucleation rate measurements.

The results were compared with the predictions of the local equilibrium model for multicomponent systems and with those derived from the theory of growth under paraequilibrium conditions. The distribution of Mn and Si in ferrite and austenite in the Fe-C-Mn-Si alloy was also measured as a function of reaction temperature with transmission electron microscopy (TEM) and energy-dispersive X-ray spectroscopy (EDX). The observed temperature below which alloying element partition ceased was in good agreement with the local equilibrium model. Whereas the parabolic rate constant for thickening was considerably larger than the amount predicted by this theory in the alloying element diffusion-controlled regime, the opposite was true in the carbon diffusion-controlled regime. Similarly, the calculated paraequilibrium constant was usually considerably larger than that measured experimentally. Synergistic enhancements of the effects of Mn and X(2) in diminishing thickening kinetics were observed for each X(2). The time-temperature-transformation (TTT) curves for the beginning of transformation were calculated from a modified Cahn analysis for the overall kinetics of grain-boundary-nucleated reactions using values of the nucleation rate and the parabolic growth rate constant computed from various models and compared with experimentally determined TTT curves. Substantial discrepancies between the calculated and measured curves were ascribed to synergistic effects of Mn and X(2) upon nucleation and growth kinetics. C1 GEOCENTERS INC,FT WASHINGTON,MD 20744.

Devices were exposed to heavy ion fluences and LETs simulating exposure in spacecraft at bias levels not expected to cause catastrophic failure. Time dependent dielectric breakdown measurements and charge separation techniques resulted in no detectable changes. The gate voltage at which oxide breakdown occurs and the gate I-V curves suggest subtle changes in device characteristics that can be detected at high gate biases. However, there is no indication that heavy ion exposure results in a significant reduction in gate oxide reliability. C1 USN,CTR SURFACE WARFARE,CRANE,IN 47522.

This vector form of the geostrophic forcing in the geopotential tendency equation is similar to the Q-vector form of the ut equation. It is shown that the horizontal components of P are the advection of geostrophic momentum, and the vertical component of P is the horizontal temperature advection. The P vectors are shown to be related to Q and C vectors, as well as the ageostrophic circulation. The three-dimensional pseudocurl of the P vector gives the C vector that equals the ageostrophic pseudovorticity in the quasigeostrophic model. The horizontal components of the pseudocurl of P are perpendicular and proportional to the Q. The horizontal divergence of the P vector is the geostrophic absolute vorticity advection while the three-dimensional divergence of the P vector is the geostrophic quasigeostrophic potential vorticity advection. The ageostrophic wind can be partitioned into the P vector (geostrophic advective) and isallobaric wind contributions. A numerical simulation of an idealized cyclone is used to characterize the distribution of the P vectors and P-vector diagnostics in order to demonstrate their potential application to the diagnosis of synoptic-scale circulations. The distribution of the P vectors clearly indicates the advections of geostrophic momentum and temperature that characterize cyclogenesis. An examination of the P vectors and the isallobaric wind demonstrates that the P vectors provide insight into the ageostrophic circulation of the cyclone. Diagnoses of the three-dimensional P-vector divergence and curl are shown to produce useful depictions of cyclonic vortex spinup and the propagation of both the large- and smaller-scale features of the system These diagnostics can be interpreted from a variety of perspectives, including the height tendency and the advection of quasigeostrophic potential vorticity. The use of P vectors to diagnose synoptic-scale circulations appears to provide potentially useful insights into the dynamics of synoptic-scale disturbances not readily obtained from other diagnoses.

The hydrogen gas absorption/desorption properties of these materials were investigated to demonstrate their application to solid state gas sensor development. These nanocrystalline materials exhibited fast response to hydrogen gas and complete recovery up to exposure to several percent of hydrogen. Suppression of the alpha-beta phase transition also was observed. The temperature dependence of the response/recovery rates indicate that the rate controlling step for absorption is the dissociative chemisorption of hydrogen on the surface of the Pd, whereas for desorption, diffusion of hydrogen out of the palladium metal was rate controlling.

It is based on a simple salve model for exploratory analysis of modern combat characteristics. The ''fractional exchange ratio'' is suggested as a robust way to compare equal-cost configurations of naval forces, because we cannot know in advance how and where the warships will fight. To aid in exposition, definitions of all terms are included in Appendix A. The methodology is illustrated with important conclusions from parametric analysis, among which are 1. Unstable circumstances arise as the combat power of the forces grows relative to their survivability. (Stable means the persistence of victory by the side with the greater combat potential.) 2. Weak staying power is likely to be the root cause when instability is observed. 3. Staying power is the ship design element least affected by the particulars of a battle, including poor tactics. 4. Numerical superiority is the force attribute that is consistently most advantageous. For example, if A's unit striking power, staying power, and defensive power are an twice that of B, nevertheless B will achieve parity of outcome if it has twice as many units as A.

RES yields from uniformly thick layers are characterized by a (cos phi)(-1) dependence, where phi is the angle between the incident beam and the target normal. Deviations from this relationship have been attributed to layers which are composed of islands, rather than films of uniform thickness. A series of BaF2 films of increasing deposition time were examined in this way. The results of this analysis show that the BaF2 at first grows in small islands which eventually coalesce into a uniform epitaxial layer. C1 CATHOLIC UNIV AMER,WASHINGTON,DC 20064.

Sera were tested at a 1:20 dilution by indirect fluorescent antibody with the use of E. canis cell-culture antigen slides. The overall prevalence of E. canis antibody was 33%. Antibody prevalence among military dogs (29%) was significantly lower than among privately owned dogs (41%; P < 0,05). The E. canis seroprevalence among dogs infested with ticks (Rhipicephalus sanguineus) was higher (44%) than that among uninfested dogs(31%; P = 0,08). The seroprevalence among military dogs varied from 21-46% at the five kennels; lower prevalences were observed in kennels with higher sanitary and hygienic conditions. Age- and sex-related E. canis antibody prevalences were not significantly different among military and privately owned dogs, although adult and male privately owned dogs had the highest seroprevalences (45% and 44%, respectively). Three dogs with epistaxis had E. canis antibody titres > 1:320. These data demonstrate the first laboratory evidence of E. canis infection among dogs in Egypt. C1 POLICE ACAD CAIRO,CAIRO,EGYPT.

For each are there is a known probability of detection if the evader traverses the are that the interdictor is inspecting. The evader must determine a probabilistic ''path-selection'' strategy which minimizes the probability of detection while the interdictor must determine a probabilistic ''arc-inspection'' strategy which maximizes the probability of detection. The interdictor represents, in a simplified form, U.S. and allied forces attempting to interdict drugs and precursor chemicals as they are moved through river, road, and air routes in Latin America and the Caribbean. We show that the basic scenario is a two-person zero-sum game that might require the enumeration of an exponential number of paths, but then show that optimal strategies can be found using network how techniques of polynomial complexity. To enhance realism, we also solve problems with unknown origins and destinations, multiple interdictors or evaders, and other generalizations.

For younger patients or for patients requiring interim treatment plans, restoring badly broken-down anterior teeth with composite resin provides an expedient and esthetic solution. Current visible-tight-activated composite resin materials require an incremental build-up to ensure adequate depth of cure. With the use of custom-contoured, stabilized, thin crown forms and strategically placed vent holes, the clinician can efficiently provide cost-effective direct composite resin restorations that meet the patients' esthetic needs.

It has been conjectured that for every complex algebraic variety X there exists a Kahler metric on the nonsingular set of X whose L(2)-cohomology is isomorphic to the intersection cohomology of X. Saper proved this conjecture for varieties with isolated singularities, using a complete Kahler metric. Similar results have been obtained by others using incomplete metrics. We give natural and explicit constructions of three types of Kahler metrics on the nonsingular set X - X(sing) of a subvariety X of a compact Kahler manifold. No restrictions on the type of singularities of X are assumed. Similar constructions can be done for nonembedded compact Kahler varieties. The first metric is Hodge if X is algebraic but is not complete on X - X(sing) if X is singular. The completion of X - X(sing) under this metric is a desingularization of X. The second metric is complete and generalizes Saper's metric for varieties with isolated singularities. Moreover each incomplete metric of the first type is naturally associated with a complete metric of the second type. The third metric is a sum of the first two and has Poincare-type growth near the singular locus of X. RP GRANT, C (reprint author), USN ACAD,572 HOLLOWAY RD,ANNAPOLIS,MD 21402, USA.

The infection in adults living with hyper- to holoendemic malaria is chronic and benign. Naturally acquired immunity to falciparum malaria is the basis of this difference. Confusion surrounds an essential question regarding this process: What is its rate of onset? Opinions vary because of disagreement over the relationships between exposure to infection, antigenic polymorphism and naturally acquired immunity. In this review, Kevin Baird discusses these relationships against a backdrop of host age as a determinant of naturally acquired immunity to falciparum malaria.

Recent evidence suggests that patients with a normal cranial CT scan after head injury can be safely discharged home from the emergency department. However, supporting data from previous studies has relied on incomplete patient follow-up. We utilized a statewide comprehensive hospital abstract reporting system (CHARS) to assess whether children with normal CT scans after head injury subsequently developed intracranial sequelae in the month following their initial injury. Design. Retrospective case-series study, with comprehensive statewide follow-up for 1 month. Setting. The emergency department of a Level 1 Trauma Center in Seattle, Washington. Participants. All children (n = 400) with head injury, Glasgow Coma Score of 13 to 15, and initial normal CT scan seen over a 4.5-year time period. All were matched against CHARS to evaluate admissions within 30 days after emergency department disposition. For readmissions, International Classification of Diseases (9th revision) discharge and procedure information was collected. All children were also matched against the state death files. Results. Four children were readmitted for neurologic reasons within 1 month following injury. One child on coumadin for heart disease developed a symptomatic subdural hematoma 5 days after head injury, requiring neurosurgical drainage. One child developed a symptomatic hemorrhagic contusion 3 days after injury, requiring observation only. Two children were readmitted 1 day after injury for concussive symptoms; both were discharged home after observation only. There were no deaths among the study population. Conclusions. Among children with a normal cranial CT scan after mild head injury, delayed intracranial sequelae requiring intervention are extremely; uncommon. In otherwise stable patients, a normal cranial CT scan can identify patients to be safely discharged from the emergency department, and would be more cost-effective than 1 to 2 days of hospital observation.

Subjects were 978 student leaders and their 1,232 followers. Results indicated that overall, leaders' behaviors as rated by followers improved after feedback. Leaders' self-evaluations following feedback became more similar to the evaluations provided by followers. Interestingly, when leaders were grouped according to whether feedback was positive, neutral, or negative based on agreement between self- and follower ratings, differences between groups in post-feedback self-evaluations and follower ratings emerged. Self-evaluations for leaders receiving negative feedback (high self- relative to followers' ratings) went down, while self-evaluations for leaders receiving positive feedback (low self- relative to follower's ratings) went up. Follower ratings of leaders who received negative feedback improved following feedback to leaders, while there was no change in follower ratings for those receiving positive feedback. Implications for using upward feedback in organizations are discussed. C1 USN ACAD,DEPT LEADERSHIP & LAW,ANNAPOLIS,MD. SUNY BINGHAMTON,SCH MANAGEMENT,BINGHAMTON,NY 13901.

Experimental K- and L(23)-edge NEXAFS data for the alkali halides and rare gas solids are compared with FEFF6 calculated results to optimize code input parameters, test code validity, and identify many-body features in these model systems. Differences are shown to arise from many-body shake-up and charge-transfer excitations. Although relatively small in the model spectra, the latter interatomic excitations are believed to be primarily responsible for the different Cl- line shapes on the passivated Al electrodes.

(Certain commercial products are identified in the article for the sake of completeness. This does not constitute and endorsement by the National Institute of Standards and Technology, the Naval Research Laboratory, or Broohaven National Lab.) The MacXAFS package is derived from a suite of EXAFS analysis programs originally written at the University of Washington. The MacXAFS package preserves the portable computational kernel of this well-tested group of programs and adds a graphical interface by using HyperCard. Communication between the core analysis programs and the HyperCard interface is done by using ASCII script files that direct the execution of the FORTRAN-based analysis programs. The user is largely insulated from the FORTRAN code, but instead interacts with the more intuitive Hypercard interface. This implementation preserves the portability of the ANSI FORTRAN programs, while taking full advantage of the platform-specific user interface features of the Macintosh. Computationally intensive programs, such as the ab initio XAFS calculation program FEFF can be executed remotely via a TCP/IP connection. Due to the clean separation of the interface and the computational kernel, this package is readily extensible by writing new programs, in FORTRAN or any other language, and adding the corresponding interface element in the HyperCard stack.

We have investigated Cs bonding environments in crown ether complexes by employing Cs-133 as a probe for XAFS studies. Crown ethers represent a good first choice for XAFS structural studies because they have well-defined first and second shell environments. Additionally, the oxygen functional groups and bond distances can be easily manipulated by choice of specific crown ether molecules. The ability of XAFS to elucidate the structural environment of Cs within the crown ether complex will be useful in additional investigations in which the Cs is selectively bound within a cage of electronegative oxygen donors including humic and other organic substances, colloidal clay minerals and ion selective exchange resins used to treat nuclear wastes.

A controversial application of MCD is the determination of the magnitude of magnetic moments and the extraction of orbital and spin contributions to the moment. To study this, we have measured, in transmission, the helicity-dependent, total absorption cross-section at the L(2) and L(3) absorption edge of Fe and Co ultrathin films deposited on 1 mu m parylene foil. Using no artificial background subtraction or curve renormalization, we obtain clean spectra for comparison with theoretical methods of the extraction of the orbital and spin contributions to the total moment.

Only 1 sublimes without decomposition under vacuum (150 degrees C); 3 is non-volatile. Crystal structures were determined for 1, 3 and the previously reported Na4Cu4(OCEt(3))(8) (2). Compounds 1 and 2 have nearly identical M(4)Cu(4)O(8) cores consisting of two puckered M(2)O(2) rings related by a centre of symmetry and joined at the oxygens by two bridging copper atoms, and at the M edges by two nearly linear O-Cu-O units. Compound 3 has a Ba2(OR)(2) ring containing the centre of symmetry and is bridged by two Cu,(OR), units that are nearly perpendicular to the Ba2O2 ring. The two BaCu2O3 planes in 3 are parallel, but separated by 0.48 Angstrom A. Hydrolysis of compounds 1-3 in THF afforded an orange or orange-brown solid that was converted to the mixed metal oxide by thermolysis, but copper and Cu2O were also produced from the Li4Cu4(OCMe(3))(8) hydrolysis product.

The polymerization reaction was characterized by Fourier transform infra-red spectroscopy and differential scanning calorimetry (d.s.c.). The disappearance of the acetylenic stretching band at 2212 cm-1 was used successfully to monitor the cure reaction. The cure reaction follows first-order kinetics with an overall activation energy of 135 kJ mol-1.

The QWB and a variety of medical, neuropsychological, and biochemical measures were administered to all participants. When QWB scores were broken down by HIV grouping, the CDC-C group was significantly lower (.614) than the CDC-B (.679), CDC-A (.754), or control group (.801). The difference between Groups CDC-C and CDC-A was about .14 units of well-being, which suggests that individuals lose 1/7 equivalents of 1 well year of life for each year they are in Group CDC-C in comparison to the asymptomatic group (Group CDC-A). In comparison to the controls, this would equal a 1-year of life loss for each seven infected individuals. The QWB was shown to be significantly associated with CD4+ lymphocytes (p < .001), clinician ratings of neuropsychological impairment (p < .04), neurologists ratings of dysfunction (p < .001), and all subscales of the Profile of Mood States. Baseline QWB scores were significant prospective predictors of death over a median follow-up time of 30 months. Multivariate models demonstrated high covariation between predictors of QWB. It was concluded that the QWB is a significant correlate of biological, neuropsychological, neurological, psychiatric, and mortality outcomes for male HIV-infected patients. C1 USN HOSP,SAN DIEGO,CA.

An ultrawideband (UWB) radar that radiates waveforms encompassing this band has recently been installed at a seaside location near the Naval Research and Development facility, Pt. Loma, San Diego, California. Propagation path loss measurements were performed at 40, 90, 140, and 190 MHz. Broadband clutter measurements were performed over the frequency band 200 to 300 MHz. The theoretical model is based on an integral equation solution for the surface fields. The surface fields are obtained using a new mathematical derivation of the integral equation for the surface fields (Ott, 1992). This new integral equation extends the frequency range of the former algorithm, WAGNER, to the VHF band. The surface fields are then integrated to obtain either the forward scatter (multipath) or the backscatter (clutter).

The difference is greater at higher strains. Despite the higher modulus, the mechanical fatigue lifetimes of double networks were found to be as much as a factor of ten higher than for conventionally crosslinked NR. The double network's tensile strength on the other hand, was slightly lower. In contrast to these results, the modulus and tensile strength in the direction transverse to the curing strain are minimally affected by the presence of a composite network.

As the system of shock triple points evolves between collisions, they trace a well shaped cellular pattern characteristic of detonations in argon-diluted, low-pressure mixtures of hydrogen and oxygen. In the region of the triple points, the shock structure evolves continuously from a single Mach structure to a double Mach structure and finally to a complex Mach structure characteristic of spinning detonations. Most of the energy released in the region of the triple points. The amount of energy release increases as the triple point comes closer to a collision with a wall or another triple point. Just before the collision, there is a large region of energy release that covers the length of the interacting transverse waves. The result is a rectangular high-energy region which boosts the propagation of the new detonation cell. C1 USN,RES LAB,COMPUTAT PHYS & FLUID DYNAM LAB,WASHINGTON,DC 20375.

It is feasible to validate metrics for controlling and predicting software quality during; design by validating metrics against a quality factor. Quality factors, like reliability, are of more interest to customers than metrics, like complexity. However quality factors cannot be collected until late in a project. Therefore the need arises to validate metrics, which developers can collect early in a project, against a quality factor. We investigate the feasibility of validating metrics for controlling and predicting quality on the Space Shuttle. The key to the approach is the use of validated metrics for early identification and resolution of quality problems. C1 USN,POSTGRAD SCH,MONTEREY,CA 93943.

Ground-based intensity observations are severely hampered by terrestrial atmospheric noise. Partial cancellation of the noise power can be achieved if two spectra having disparate signal-to-noise ratios, and based on time series acquired simultaneously at the same site, are combined. A method of combining the spectra is suggested in which one amplitude is scaled and subtracted from the other. The result is squared yielding a positive-definite power density. To test the method, the intensity of light scattered by the Earth's atmosphere was recorded at fifteen-second intervals in two narrow bands centered on 0.5 mu and 1.6 mu. When the two resulting spectra were combined, the noise power was attenuated by a factor of 2.7. The scale factor was varied about its optimum value, revealing that noise peaks have a different signature than signal peaks, and opening up the possibility of a new tool in discrimination against noise peaks. Maxima at symmetry-allowed frequencies and minima at symmetry-forbidden frequencies indicate that the probability that these results are obtained by chance is only 6.1 x 10(-4). The positions of these maxima and minima also support the solar-cycle dependent frequency shifts found by Palle, Regulo, and Roca Cortes (1990a).

The average temperature deduced from S XV is demonstrated to vary with the solar activity level: A temperature of 2.5 x 10(6) K is derived from the spectra taken during low solar activity, similar to the general corona, while 4 x 10(6) K is obtained during a higher activity phase. For the latter, the high-temperature tail of the differential emission measure of active regions is found most likely due to the superposition of numerous flare-like events (micro/nano-flares).

Review of the literature identified the hypothesis that E tarda infections may occur more frequently in immunocompromised patients. Previous animal studies have shown decreases in lymphocyte function during hypothyroidism, with return of normal lymphocyte function during euthyroid states. Therefore, lymphocyte transformation studies were obtained, demonstrating severe decreases in our patient's lymphocyte function. Except for chronic autoimmune thyroiditis, other immune system abnormalities were excluded. Serial lymphocyte transformation studies showed gradual improvement in lymphocyte function during gradual return to euthyroid state. Possible pathophysiologic mechanisms for these findings will be reviewed. C1 USN HOSP,DEPT INTERNAL MED,DIV INFECT DIS,PORTSMOUTH,VA. USN HOSP,DEPT INTERNAL MED,DIV ENDOCRINOL,PORTSMOUTH,VA.

It is based on a systematic experimental procedure to observe the response of composite materials subjected to multiaxial load environment. The energy dissipated by internal failure mechanisms is employed as a measure of internal damage and is characterized by an energy dissipation function, which is identified by means of a deconvolution procedure using data provided by NRL's automated in-plane loader testing machine. Part II of this work will display the dissipated energy density distributions in composite specimens that are used for the in-plane loader machine and naval structures, while Part III presents a general theory that includes the derivation for the constitutive behavior of the damaged composites.

GENERAL MATERIAL CONSTITUTIVE RELATION SO THEORETICAL AND APPLIED FRACTURE MECHANICS LA English DT Article AB While the energy dissipation function can be approximately determined without explicit knowledge of the damage-induced constitutive nonlinearities as discussed in Parts I and II of this work, a more refined approximation requires a representation of the full-scale nonlinear behavior. This information is also of much interest in its own right since it is needed for stress analysis when analyzing the behavior of structural components loaded well into the nonlinear response range where substantial load redistribution is expected.

This transient analysis is carried out for various simple targets of interest, in the time-domain, in the frequency domain and in the combined time-frequency domain. The first two, more traditional, approaches are contrasted with a third and more recent processing scheme in the combined time-frequency domain, which utilizes the windowed or pseudo-Wigner distribution (PWD). This third processing approach exhibits the time-evolution of the target resonances in a more informative way and it is seen to offer additional advantages for target identification purposes. We display calculations showing the quite different patterns generated by the echo of each target, which can then be used unambiguously and remotely to characterize them. The procedure, implemented here for the PWD, could be repeated using any of the many distribution members of the general bilinear class. C1 NATL DEF RES ESTAB,S-17290 STOCKHOLM,SWEDEN.

The phenomenon was formally investigated. Twenty-four immature, male, castrated, pure-bred Yorkshire swine were conditioned by treadmill running, while 34 control pigs remained sedentary. All pigs (weight 18.75-21.90 kg) were dived on air to 200 feet of seawater (fsw) in a dry chamber. Bottom time was 24 min. Decompression rate was 60 fsw/min. Pigs that developed neurologic DCI were treated by recompression, Pigs without neurologic signs were considered neurologically normal if they ran on the treadmill without gait disturbance at 1 and 24 h postdive. Of the 24 exercise-conditioned pigs, only 10 (41.7%) developed neurologic DCI, compared to 25 of 34 (73.5%) sedentary pigs (X(2) = 5.97; P = <0.015). Neither mean carcass density (adiposity) nor mean age were significantly different between groups. No patent foramen ovale was detected at necropsy. An additional control group of 24 pigs was dived to clarify the influence of weight. The results suggest that the risk of neurologic DCI is reduced by physical conditioning, and the effect is independent of differences in age, adiposity, and weight.

Major components of costs and revenues and the major stakeholders are identified and a model is developed to determine the system configuration (e.g. cell size, number of channels, etc.) which will maximize the annual expected net revenues to the system operator. Key properties relating the various parameters of interest are derived. The results of computational experiments are presented and their implications are dis-. cussed. The computational results show that the optimal net revenue curves have a saw-tooth structure with two types of teeth; Large ones that come from switching between cellular technologies, and smaller jumps come the discretenes of base stations. The importance of capturing a high fraction of potential users, in early stages of cellular system introduction is investigated. Finally, the cost of competition and its implications for the regulatory agency and the cellular service providers are analyzed. It is shown that by dividing the available frequency spectrum between too many system operators, the overall value of the cellular system is reduced when compared to an approach which uses division of the overall service area into a larger number of service areas, each with only two system operatos. The above results have profound implications on public policies for frequency spectrum allocation. C1 [Gavish, Bezalel] Vanderbilt Univ, Owen Grad Sch Management, Nashville, TN 37203 USA.

It is shown that with the addition of carbon, the amorphous silica phase present at the grain boundaries is reduced to SiC, which forms particulates at the grain boundaries. These particulates (a) inhibit further coarsening of grains and (b) serve as reinforcements to enhance creep resistance. Since creep deformation rates are extremely sensitive to grain size in these materials, to observe reinforcement effect the creep rates need to be compensated for the grain size effects. On the basis of the grain size compensated creep rates, it was found that an addition of 2 wt.% carbon is as effective as 20-30 vol.% reinforcement of SiC. The effect of particulate reinforcement on creep of MoSi2 is examined after compensating for grain size effects. It is shown that (a) volume fractions greater than 20% are needed to have a noticeable effect of reinforcement, and (b) among all reinforcements examined so far SiC provides the best reinforcement.

The polymers are based on aminopropyl end-capped dimethylsiloxane oligomers, isophorone diisocyanate, and 1,4-benzenedimethanol. Effects of segmental length and annealing on the surface composition were investigated. It was found that when the average molecular weight of the siloxane segments reaches 27K, the topmost surface region (within 18 Angstrom of the free surface) of a film cast from tetrahydrofuran solution is nearly pure siloxane phase. To achieve a comparable degree of surface phase concentration in films of copolymers with a siloxane segmental molecular weight of 10K, annealing at 120 degrees C for 15 min was required. Depth profiles based an these data showed that in as-cast films a siloxane deficient (hard-block enriched) phase several nanometers thick occurs beneath the siloxane surface layer. Annealing increases the thickness of both the siloxane-enriched and the siloxane-deficient regions. C1 OFF NAVAL RES,DIV CHEM,ARLINGTON,VA 22217. SUNY BUFFALO,DEPT CHEM,BUFFALO,NY 14214.

III stellar interferometer on Mt. Wilson under a wide variety of seeing conditions. On almost all nights, the high-frequency portions of the temporal power spectra closely follow the form predicted by the standard Kolmogorov-Tatarski model. At lower frequencies, a variety of behavior is observed. On a few nights, the spectra clearly exhibit the low-frequency flattening characteristic of turbulence with an outer-scale length of the order of 30 m. On other nights, examination of individual spectra yields no strong evidence of an outer scale less than a few kilometers in size, but comparison of the spectra on different interferometer baselines shows a saturation of the spatial structure function on long baselines. This saturation is consistent with the assumption of an outer-scale length similar to that derived for the nights when low-frequency flattening of the spectra is clearly seen. We discuss possible explanations of this behavior and conclude that power spectra from a single interferometer baseline are a poor diagnostic for the effective outer scale compared with multiple-baseline spectra.

Although plasma with the neon-rich photospheric composition is rare in the corona, it always occurs where new flux is emerging. This suggests that the neon richness of the plasma reflects its recent photospheric origin, not its closed-loop magnetic topology as has been assumed in the past. Such a ''volcanic'' process would be consistent with our observations of sunspots, which have the Ne-rich composition when they lie next to a neutral line where flux is emerging, but have the Mg-rich composition when they are surrounded by a ''buffer zone'' of like-polarity flux.

The flare was observed simultaneously in the soft X-ray Ca XIX line by the Yokhoh Bragg Crystal Spectrometer (BCS) and in hard X-rays (>50 keV) by the CGRO Burst and Transient Spectrometer Experiment (BATSE). A strong stationary component of Ca XIX emission was present at the start of impulsive hard X-ray emission indicating an extended phase of heating prior to the production of energetic nonthermal electrons. We interpret the preflare Ca xrx emission as a signature of Joule heating by field-aligned currents. We relate the temporal variation of impulsive hard X-ray emission to the rate of runaway electron acceleration by the DC-electric field associated with the current. We find that the initial rise in hard X-ray emission is consistent with electron acceleration by a DC-electric field that increased from a preflare value of less than or similar to 10(-5) V cm(-1) to similar or equal to(9 +/- 1) x 10(-5) V cm(-1) at the time of the first hard X-ray peak and then remained constant during the rest of the impulsive phase. We attribute the increase in electric field strength to the formation of a current sheet at the reconnection point of two loop structures. The decrease in hard X-ray emission after flare maximum is consistent with a reduction in the number of runaway electrons due to an increase in coronal density produced by chromospheric evaporation. The increased density quenches the runaway process by enhancing collisional thermalization of electrons. To avoid the generation of an unrealistically large magnetic field, the flaring region must be highly filamented into greater than or similar to 10(6) oppositely directed current channels of similar to 30 cm width with an initial preflare current of similar or equal to 3 x 10(10) A per channel.

The presence of well defined sharp peaks in the 550 to 600 nm elastic scattering spectra confirmed that each microcrystal acts as an optical cavity with cavity quality factors exceeding 10(4). Such natural resonator microcrystals should lead to greatly enhanced local field effects near the surface of CdS, quantum electrodynamic modification of optical transition rates of nearby species and altered photochemistry. Absorptive heating following high intensity laser irradiation was found to induce a transient washout of the high Q modes. C1 USN, RES LAB, WASHINGTON, DC 20375 USA.

The measurements cover a period of 262 days from January 23, 1992, to October 13, 1992. During this campaign it was possible to retrieve useful daily mixing ratio profiles for 186 days. We thus have a nearly continuous record of water vapor mixing ratios for altitudes from approximate to 35 to 75 km. The retrievals are obtained using the optimal estimation method. Details of the error analysis are presented, and a technique is introduced that reduces baseline effects and helps to estimate the baseline error. The high-altitude (greater than or similar to 65 km) data show a sharp rise prior to the expected maximum near the summer solstice and a gradual decline in the following months. The mixing ratios generally peak between 55 and 65 km, at which point the mixing ratios are 6-7 parts per million by volume. The highest peaks occur in January, May, and October.

The material was studied by means of X-ray diffraction and magnetic susceptibility measurements. The superconducting phases reproduced from this synthesis, without recourse to high temperature anneal, have properties consistent with those of vapor doped materials. The observed magnetic properties are interpreted in terms of the grain size and the links between the grains.

At the center of the ice sheet where the ice surface is nearly level, surface comparisons show a fit at the 1 to 3 m level as expected, but even at moderately sloping ice regions (0.3 degrees - 0.6 degrees), satellite altimetry mean errors in the range of 10 to 35 m are observed. These errors are found for slope-corrected and waveform-retracked data, so most previous accuracy estimates of current satellite altimetry ice sheet elevations in regions of sloping or undulating ice appear to be too optimistic.

With increase in Al content from 13 to 50 at.%, microstructures change from (alpha + beta) to (alpha(2) + beta) to (alpha(2) + gamma) and finally to gamma where alpha(2) is Ti3Al and gamma is TiAl. The exact microstructure for a given alloy depends on the composition, presence of ternary elements that stabilize beta, such as Nb, and heat treatment. The degrees of slip planarity and brittleness increase with increase in Al content as one proceeds from alpha to alpha(2) to equiatomic alpha. In addition, there is an increase in the propensity for faceted mode of crack growth with an increase in the degree of slip planarity. Fatigue threshold for a faceted crack growth depends on grain size or obstacle spacing. Hence crack growth rates can vary significantly for a given alloy depending on the microstructural scaling parameters, namely, equiaxed grain size or inter-obstacle spacing for Widmanstatten precipitates with basket-weave or lamellar structure. The load ratio effects have been analysed using the two parametric approach developed by the authors, and it is shown that the results can be explained without invoking an extraneous factor, namely crack closure.

Wavefunctions and energies are calculated using the Hartree-Fock method with relativistic corrections. The results of these calculations are then compared to predictions obtained using scaling relations developed previously from detailed calculations of DR for O-like Ar10+, Ti14+, Fe18+ and Se26+. These relations are strictly valid for predicting DR data between Ar10+ and Se26+, but they can also be extrapolated to predict the data for Mo34+. We find that, except in a few cases where the data show strong Z dependences, they are accurate to within or better than a few per cent of the detailed, calculated Mo34+ data. Comparisons are also made with results of other published work for Mo34+ as well as for other O-like ions. As expected, from earlier calculations, the results of this calculation are in much better agreement with those obtained using a fully relativistic MCDF calculations than those obtained using a non-relativistic LS coupling calculation without any relativistic corrections.

The effects of the duration of H(sat) period on leaf growth rates, root protein metabolism and plant carbohydrate stores of eelgrass were investigated. Growth rates declined linearly with decreasing H(sat). Protein synthesis in roots subjected to 2 h H(sat) was elevated in the first 10 min of aerobiosis during the transition from anaerobic metabolism. This elevation of protein synthesis capacity was not observed in roots from 4 and 12 h H(sat) treatments. Root tissue age had a significant effect on protein metabolism, with rates of protein synthesis in root bundle no. 1 (youngest) 58% higher than those of bundle no. 3. This age dependency was also observed in root protein content. Soluble carbohydrate levels in root bundle no. 1 and leaf no. 2 decreased linearly with H(sat) period, while reductions in rhizome segment no. 1 were not significant. Levels in all tissues subjected to the 2 h H(sat) treatment were 57% of levels following the 12-h treatment. Although protein synthesis in Z. marina root tissue was influenced only slightly by the anoxia associated with reduced irradiance during these short (10-14 day) periods, longer and/or more severe periods of light limitation may disrupt root protein metabolism due to carbohydrate starvation.

In this paper we present quantitative results for these flare knots, in relation to other flare regions, for four relatively ''simple'' flares. Emission measure distributions, electron temperatures, and electron densities are derived from SXT and Yohkoh Bragg Crystal Spectrometer observations. The four flares selected are dominated by what appear to be single-loop structures, with bright knots at the loop tops. The flares are neither long-duration nor impulsive events. The spatial distributions of brightness and emission measure in the flares are found to be quite similar for all four events, even though there are significant differences in dynamical behavior between at least two of the events. Temperatures and densities calculated for these hares are consistent with previous results from many solar experiments. An investigation of intensity correlations between adjacent pixels at the tops of the loops suggests the existence of local disturbances in the magnetic loops that occur on spatial scales less than the radii of the loops.

They also compared the various definitions of the vortex formation region length which have been proposed by Gerrard (1966), Griffin (1974), and others for both high and low Reynolds numbers. The purpose of this note is to expand the work of Green and Gerrard, and to further their proposition that the end of the vortex formation region at all Reynolds numbers mark both the initial position of the fully shed vortex and the location at which its strength is a maximum. The agreement discussed here between several definitions for the formation region length will allow further understanding to be gained from investigations of the vortex wakes of stationary bluff bodies, and the wakes of oscillating bodies as well.

Volterra integral equations are derived from the convolution integral which address substructure coupling and structural modification. The theory is cart in physical coordinates and, therefore, no transformation or mode truncation is required to achieve model reduction, As a minimum, only those coordinates directly involved in the synthesis need be retained, although synthesized transient response can be found for all coordinates, if so desired. The formulation makes use of transient response data and impulse response functions at the retained physical coordinates. Modified or coupled transient response is directly calculated; no synthesized system model is assembled. The formulation exactly synthesizes system damping, regardless of the uncoupled system damping models used, The numerical solution of the integral equations involves the solution of a lower triangular linear system only; no matrix factorization or eigensolution is required. Simple yet representative numerical examples are included. RP GORDIS, JH (reprint author), USN,POSTGRAD SCH,DEPT MECH ENGN,MONTEREY,CA 93943, USA.

METHODS: Thirty asymptomatic volunteers were studied with gadolinium-enhanced MR (0.1 mmol/kg) of the lumbar spine. The precontrast axial T1-weighted sequences were reviewed for the entry section phenomenon of flow-related enhancement. If present, the sequence was repeated in combination with a superior saturation pulse in an attempt to eliminate this phenomenon. All studies were reviewed to document the incidence of radicular enhancement and determine its association with the entry section phenomenon. RESULTS: The entry section phenomenon was observed in 16 of 30 volunteers with successful elimination obtained in all cases. Eighteen of the volunteers demonstrated radicular enhancement; 16 of the 18 enhancing roots were associated with the entry section phenomenon. CONCLUSIONS: Radicular enhancement occurs commonly in asymptomatic volunteers. This phenomenon most likely represents the enhancement of prominent radicular veins. We urge caution in interpreting this finding as abnormal in the symptomatic population with degenerative disk disease. C1 USN HOSP,DEPT NEUROSURG,OAKLAND,CA 94627.

Outpatient surveillance of 20,859 U.S. troops deployed during the first eight weeks, however, indicated that a mean of only 0.8% (range 0.5-1.2%) of personnel sought care for diarrhea each week, and in three epidemiologic surveys, < 3% of troops reported experiencing a diarrheal illness per week. Despite these low overall attack rates, diarrhea accounted for 16% of 381 hospital admissions and 20% of 245 patients admitted with a temperature greater than or equal to 38.5 degrees C. Sixty-one specimens were obtained from inpatients and 52 were obtained from outpatients. Shigella sp. were isolated from 33%, enterotoxigenic Escherichia coli from 16%, Giardia lamblia from 4%, and rotavirus from 1% of 113 stool samples obtained from inpatient (61) and outpatient (52) troops with diarrhea. Bacterial isolates obtained in Somalia were resistant to doxycycline (78%), ampicillin (54%), and sulfamethoxazole (49%), but uniformly sensitive to ciprofloxacin. With the exception of 10 Shigella sonnei isolates that were linked epidemiologically to one eating facility, bacterial pathogens occurred sporadically and demonstrated a wide variation of serotypes and antibiotic sensitivity patterns. Additionally, three of 11 paired sera collected from persons with nausea, vomiting, and watery diarrhea demonstrated a four-fold or greater increase in titer to Norwalk virus antibody. These data indicate that large outbreaks of diarrheal disease did not occur; however, highly drug-resistant enteric bacteria, and to a lesser extent viral and parasitic pathogens, were important causes of morbidity among U.S. troops in Somalia.

Involvement of the head and neck is rare and is typically dental in origin. Despite broad-spectrum antibiotics, mortality rates for this disease remain high. We report a successfully treated case of necrotizing fasciitis arising from a peritonsillar abscess. Review of the literature reveals only 6 other cases, with 3 successful outcomes. Early diagnosis, broad-spectrum antibiotics, and aggressive surgical debridement are the cornerstones of therapy. The pathophysiology is typically a mixed aerobic and anaerobic infection. Supportive treatment options such as hyperbaric oxygen therapy and high-calorie supplemental nutrition may be of benefit. A comprehensive literature review of craniocervical necrotizing fasciitis is presented. Factors associated with poor outcomes include diabetes mellitus, mediastinitis, cardiovascular disease, and peritonsillar abscess.

Design: Retrospective survey. Setting: Academic tertiary care referral center. Patients and Intervention: The medical records of 96 patients treated with induction chemotherapy followed by definitive radiation therapy were reviewed; 18 of these patients requiring a surgical salvage procedure after completing chemotherapy and radiation therapy and these constituted the study group. Main Outcome Measures: Major wound complications. Results: Major wound complications occurred in 11 (61%) of the 18 patients. Surgical salvage within I year of initial treatment had a 77% incidence of major wound complications vs a 20% incidence if performed 1 year after intial treatment. The mean time to resolution of fistulae and flap necrosis was 7.7 months. Two deaths were attributed to major wound complications: one patient had a carotid blowout; one had postoperative pneumonia. Conclusions: Salvage surgical procedures performed after induction chemotherapy and definitive radiation therapy have a high rate of major wound complications. This should be considered when assessing organ preservation treatment strategies. C1 UNIV MICHIGAN,DEPT OTOLARYNGOL,ANN ARBOR,MI 48109. USN,MED CTR,DEPT OTOLARYNGOL HEAD & NECK SURG,PORTSMOUTH,VA.

The temporal coverage during the program was approximately three scans per day. A few days into the VLA program, UX Ari began a radio flaring period which lasted for at least 2 weeks. All the radio fluxes were above the system noise during this episode, but the largest values (up to 270 mJy) occurred close to 0.0 phase. This phasing is confirmed by the UX Ari radio observations of Neidhofer, Massi, and Chiuderi-Drago (1993). Visible-band light curves of UX Ari were obtained both during and after our radio observations; the peak-to-peak variation in all filters was approximate to 0.2 mag. The light curves indicate that the maximum starspot visibility occurred very close to 0.0 phase, the same phase as the radio maxima. Closer comparison of our radio and optical light curves indicates that they are almost perfectly anticorrelated. A similar radio/optical correlation has been found by Lim et al. (1992) and Lim et al. (1994) for the single KO V star AB Dor. We make the following conclusions from our observations. First, the episodes of long-term (similar to hours to days) radio flaring were modulated by stellar eclipses. Second, the flares were located close to the starspot groups. Third, the sizes of the flares were comparable to sizes of the starspot groups, which is consistent with nonthermal emission of brightness temperature T-b similar to 10(10-13) K. Fourth, the radio emission arose only from the midlatitude starspot groups. Last, the radio flares emitted their radiation nearly normal to the stellar surface.

THEORETICAL CONSIDERATIONS SO ASTROPHYSICAL JOURNAL LA English DT Article DE MHD; PLASMAS; SUN, CORONA; SUN, FLARES ID X-RAY FLARE; TEMPERATURE DIAGRAM; TRANSITION REGION; LOOPS; DYNAMICS; MODEL; CORONA; GASDYNAMICS; EVOLUTION; EMISSION AB Theoretical models of the cooling of flare plasma are reexamined. By assuming that the cooling occurs in two separate phases where conduction and radiation, respectively, dominate, a simple analytic formula for the cooling time of a flare plasma is derived. Unlike earlier order-of-magnitude scalings, this result accounts for the effect of the evolution of the loop plasma parameters on the cooling time. When the conductive cooling leads to an ''evaporation'' of chromospheric material, the cooling time scales as L(5/6)/p(1/6), where the coronal radiative loss function is assumed to vary as T--1/2 and quantities are evaluated at the start of the decay phase (defined as the time of maximum temperature). When the conductive cooling is static, the cooling time scales as L(3/4)/n(1/4). I, deriving these results, use was made of an important scaling law (T proportional to n(2)) during the radiative cooling phase that was first noted in one-dimensional hydrodynamic numerical simulations (Serio et al. 1991; Jakimiec et al. 1992). Our own simulations show that this result is restricted to approximately the radiative loss function of Rosner, Tucker, and Vaiana (1978). For different radiative loss functions, other scalings result, with T and n scaling almost linearly when the radiative loss falls off as T-2. It is shown that these scaling laws are part of a class of analytic solutions developed by Antiochos (1980b). C1 USN, RES LAB, DIV SPACE SCI, WASHINGTON, DC 20375 USA.

These data were extracted from electrographic images obtained with two cameras during a shuttle flight in 1998 April/May. The cameras provided band passes with lambda(eff) = 1375 Angstrom and lambda(eff) = 1781 Angstrom. Synthetic colors show that these bands are sensitive to effective temperature for hot stars. Our measurements were placed on a quantitative far-ultraviolet magnitude scale by convolving the spectra of stars observed by IUE with our cameras' spectral response functions. Fifty-eight percent of the ultraviolet objects were identified with visible stars using the SIMBAD database while another 40% of the objects are blends of early type stars too close together to separate with our resolution. Our photometry is compared with that from the TD-l, OAO 2, and ANS satellites and the S201 (Apollo 16) far-ultraviolet camera and found to agree at the level of a few tenths of a magnitude. Unlike previous studies, almost half of the identified visual counterparts to the ultra-violet objects are early B stars.

Many pilots wear required corrective lenses during flight operations, and many wear tinted lenses. What happens to these during ejection? What injuries are a result of the eyewear? What factors can be identified that influence retention of the eyewear and severity of related injury? Do contact lenses provide significant advantages' There were 48 ejections occurring between 1977 and 1990 that involved corrective or tinted lens use that were retrospectively examined using Naval Safety Center records and personal questionnaires. There ware five contact lens wearers included. Retention rates were calculated as functions of several variables. Although 37 of 46 lost all lenses, each instance of retention occurred with visor down, oxygen mask on, helmet properly secured, and at lower ejection speeds. Related injuries were minor and occurred in only 20%. The utility and need for enforcement of standard operating procedures (i.e., mask on, helmet secured, and visor down) was clearly demonstrated. Only 19 of 46 clearly met all 3 criteria. Contact lens users were too few to allow meaningful conclusions. C1 USN,AEROSP MED INST,PENSACOLA,FL.

However, in the past, there have been few methodologies available for the investigation of team performance. The present manuscript attempts to contribute to this area of research by describing the rationale underlying the use of computer-based simulations in research on team performance. This is followed by a review of the networked simulations that are currently being used in team-performance research. This review emphasizes the capabilities provided by the networks and the types of research concerns for which they are effective.

However, DBNP is not commercially available; therefore, it had to be synthesized in the laboratory prior to toxicity studies. The DBNP was prepared from 2,6-di-tert-butylphenol (DBP) precursor in hexane through an electrophilic aromatic substitution process using NO2. A collective yield of 75% was obtained by using two empirically determined end points that prevented the coprecipitation of reaction by-products and resulted in the formation of DBNP in high purity. Excessive amounts of NO2 in reaction mixtures resulted in the decomposition of preformed DBNP. With a pK(a) value of 6.8 and a higher degree of lipophilicity, DBNP may prove to be a stronger uncoupler of oxidative phosphorylation than 2,4-dinitrophenol (pK(a) = 4.09) due to the expected enhancement of passive-diffusion kinetics across biological membranes at the physiological pH of 7.4. The present study is intended to provide analytical toxicologists, industrial hygiene monitors, and other professionals involved in chemical health and safety with a comprehensive source of basic information on the synthesis and analytical chemistry of DBNP.

Theoretical predictions are experimentally verified with AlInAs-GaInAs HBT's using femtosecond visible-wavelength optical pulses for photocarrier injection and electro-optic sampling for subpicosecond-resolution electrical response measurements; additional sampling-oscilloscope observations allow accurate responsivity measurements and provide time-response information to nanosecond time scales. The HBT photocarrier transport description is shown to be in good qualitative agreement with the significant features of the measured transients, and the time scales of the transients can be predicted with good accuracy from simple expressions involving equivalent-circuit device parameters. The model suggests ways of improving an HBT's photoresponse bandwidth; operating be derived at which slower photoresponse be dramatically reduced in amplitude. An experimentally measured HBT optical response of 2.4 ps, corresponding to a photocurrent bandwidth of more than 200 GHz, is unsurpassed for an active device. C1 MOTOROLA INC,MESA,AZ 85283.

Five pump wavelengths corresponding to transitions from the metastable I-4(13/2) state to the H-2(11/2) State generated upconversion laser emission at 549.8 nm. The dependence of the laser output power on pump power near laser threshold is discussed in terms of a four-level kinetics model and is shown to reflect the threshold power requirement for photon avalanche. The maximum output power at 7K was 33 mW, giving an optical conversion efficiency of 3.5% and a conversion efficiency of 28% based on absorbed power. Pumping Er:YALO by cross relaxation energy transfer produced 166 mW of laser output with an optical conversion efficiency of 17%.

The filter consists of eight taps with progressively longer segments of high-dispersion fiber, but completed with dispersion-shifted fiber to nominally identical overall lengths. The time delays through each tap are tuned by varying the wavelength of the optical carrier. The constructed 8-tap filter exhibits bandpass characteristics with a Q of 30. The bandpass band is continuously tuned over a full octave from under 9 GHz to over 18 GHz with a single low-voltage control signal that demonstrates the technique's applicability to adaptive systems.

For certain values of length and radius and assuming that 1 < upsilon < 2, we have determined new shapes that are appropriate for high speed missile radomes. We have found that the superspheroid with optimized exponent value upsilon = 1.381 can almost exactly reproduce the traditional Von Karman radome geometry. Incidence angle maps and geometric properties have been determined for this superspheroidal family. We have used a ray tracing analysis to obtain boresight error induced by this family of shapes as a function of gimbal angle. The superspheroids are mathematically simple, can approximate most of the traditional radome geometries quite well, and are exceptionally easy to either program or use analytically.

A feedback loop in the response system with an identical filter is used to reconstruct the original drive signal, allowing synchronization. A simple parameter switching scheme is used to send information from a drive circuit to a receiver. It is also possible to add a chaotic signal with very similar frequency characteristics and still detect information encoded in the original chaotic carrier (but not the added chaotic signal), demonstrating the possibility of adding and separating multiple chaotic carriers with similar frequency characteristics.

Users in the system employ complex signature sequences, which are modeled as deterministic sequences. We present upper and lower bounds for the probability of bit error (p.b.e.) of a reference transmission. First, the conditional p.b.e. given the multiple-user interference (MUI) is obtained. Then, the conditioning is removed by averaging over the discretized probability density function (p.d.f.) of the MUI. The result is an upper (or lower) bound when the discretized p.d.f. is a shifted-high (or shifted-low) version of a sectioned p.d.f. This process requires the two-dimensional p.d.f. of the MUI, which is derived in this paper. Arbitrarily tight bounds can be obtained at the cost of increased computation. Numerical results are presented for complex FZC and Near Optimal 4-Phase sequences, as well as real binary Gold sequences, for BPSK, 4-PSK, and 8-PSK. Gray code bit mapping is assumed, although the analysis can be applied to other bit mappings. Results show that complex sequences can yield better performance than binary sequences in MPSK signaling. Using complex sequences, the number of available signature sequences is greatly enlarged. C1 UNIV MASSACHUSETTS,DEPT ELECT & COMP ENGN,AMHERST,MA 01003.

The objective is to determine a conflict-free schedule of minimum length that satisfies the specified end-to-end communication requirements. It is well known that this problem, in almost all of its forms, is a combinatorial-optimization problem of high complexity. We approach this problem by the use of a Hopfield neural network model in which the method of Lagrange multipliers is used to vary dynamically the values of the coefficients used in the connection weights.

The assumption of independent and identically distributed (i.i.d.) samples requires the integrator in the receiver to be reset periodically, This introduces loss in the effective signal-to-noise ratio, degrading the performance. In this paper, on the contrary, our two sequential schemes use continuous integration, It can be shown that the likelihood ratio is monotonic; consequently, the tests can be easily implemented in realtime, Methods are proposed for designing the decision thresholds to achieve the desired false-alarm and miss probabilities, Performances of the proposed schemes are obtained and they suggest that the TSPRT is more desirable, The effect of slowly-varying channel fading is also investigated, Results show that fading does not affect the false alarm probabilities, but it can drastically reduce the probability of detecting the alignment of the two PN sequences, especially when the fading is severe.

In introductory engineering courses it is also important that the students learn to perceive the computer as a tool and not as an end in itself. Achieving these goals requires a careful integration of computer usage into such courses by the instructors. In this paper we examine this issue in the context of a first course in electrical engineering that has been taught at the U.S. Naval Academy, and we present specific examples of assignments we have used in our effort to accomplish these goals.

The serpentine structure is formed by folding a double-ridged rectangular waveguide so that the orientation of the magnetic field changes (H-plane bend) instead of the conventional E-plane bend configuration. The H-plane bend structure has the potential for the production of high power, broad band radiation. For a cold beam, the linear theory predicts a gain of 2.0-2.5 dB/cm and a bandwidth of 20-25% in the millimeter wave frequencies. The bandwidth is sensitive to the axial velocity spread of the beam. The bandwidth decreases to 10% at delta upsilon(z)/upsilon(z) = 3%. Means to suppress the backward wave oscillations have to be applied for using the full bandwidth.

One application of Raman fiber optic chemical sensors is the characterization of the contents of nuclear waste tanks. In these tanks it is expected that approximately 20 meters of optical fiber will be exposed to radiation levels between 100 and 1000 rads/hour. In support of this work two silica optical fiber types (one a communications grade fiber and the other nominally radiation resistant) have been tested at the radiation levels expected in the tanks. Luminescence and Raman scattering measurements have been performed in situ with 488-nm excitation on two types of silica optical fiber exposed to a constant low to moderate dose rate of gamma radiation of 880 rads(Si)/hour from a Co-60 source for a total dose of greater than 45 krads. The nominally radiation-resistant fiber was also excited with 514.5-nm and near-infrared 830-nm laser radiation. The rate of the silica Raman signal fdecrease is more than three times greater for the visible excitation wavelengths than for the 830-nm excitation for the radiation resistant fiber. The behavior of the 650-nm photoluminescence line upon irradiation was different for the two fibers studied, both in terms of the shift of the 650-nm line and rate of increase of the normalized photoluminescence intensity. In all cases the photoluminescence from the fibers was less than the Raman intensity. No radioluminescence was observed in either fiber. The radiation resistant fiber exhibited photobleaching effects on the Raman transmission when photoannealed with 488-nm laser light.

Up to 100% removal of trace quantities of thorium (approx. 1.00 ppm in 0.01 N H2SO4) from solution occurred within 3 h with fluorite and within 48 h in the case of bentonite. Quartz, jarosite, hematite, sodium feldspar, gypsum and galena removed less than 15% of the thorium from solution. In the coprecipitation studies, barite, anglesite, gypsum and celestite were formed in the presence of thorium (approx. 1.00 ppm). Approximately all of the thorium present in solution coprecipitated with barite and celestite; 95% coprecipitated with anglesite and less than 5% with gypsum under similar conditions. When jarosite was precipitated in the presence of thorium, a significant amount of thorium (78%) was incorporated in the precipitate. C1 AMERICAN UNIV,DEPT CHEM,WASHINGTON,DC 20016.

Such sleep responses represent one facet of the acute phase response and are thus probably beneficial to the host. Certain bacterial cell wall products such as lipopolysaccharide and peptidoglycan and viral double-stranded RNA also induce sleep responses. These microbial products share the ability to enhance cytokine production. Some cytokines such as interleukin-1, tumor necrosis factor, interferon-alpha and acidic fibroblast growth factor are somnogenic. Cytokines in turn alter production of neuroendocrines and neurotransmitters, e.g., growth hormone releasing hormone and nitric oxide, which are known to be involved in sleep-wake regulation. Microbial-altered sleep thus likely involves an amplification of ongoing normal sleep regulatory mechanisms. C1 OFF NAVAL RES,DEPT IMMUNOL & MED MAT,ARLINGTON,VA 22217.

Starting with experimentally observed properties common to the kinetics of both repolarizing membrane currents and cardiac action potential responses to sudden changes in cycle length, extremely elementary dynamical assumptions are made concerning current activation and decay, and repolarization threshold. A two-parameter family of one-dimensional dynamical systems emerges. The resulting systems are analytically tractable in considerable detail generating restitution curves, bifurcation schemes, rhythmic responses and chaotic behavior for a representative cardiac cell. The excellent qualitative and quantitative agreement with experimental data reported for several cardiac preparations is discussed. The two-dimensional analog produces unexpected basin behavior which could be of clinical significance in explaining how a single extra beat or a pause could alter subsequent action potential behavior and cause dispersion of refractoriness across the ventricle increasing the risks for arrhythmias. By having a manageable number of parameters, analytically defined patterns of behavior, and computational ease, this dynamical system has the potential to be used in computer simulations to study the effects of antiarrhythmic drugs on complex two- and three-dimensional reentrant substrates, or used on line by an interactive pacemaker.

A comparison of their statistical formulas suggested that they should yield different answers to the meta-analytic questions of central tendency, variability, and prediction by moderators. These frameworks were used to analyze systematically differing databases and showed that, although the techniques of L. V. Hedges and I. Olkin (1985)and of R. Rosenthal and D. Rubin(e.g., 1978, 1988; Rosenthal, 1991)tended to produce reasonable and convergent results, the results of J. E. Hunter, F. L. Schmidt, and G. B. Jackson( 1982; Hunter and Schmidt, 1990) often diverged from the other 2 frameworks. For example, consistent with the law of large numbers, finding more studies with the same result is less likely to occur because of chance alone; the Hedges and Olkin and the Rosenthal and Rubin approaches confirmed this prediction, but the Hunter et al. approach did not. The distinct tendency of the Hunter et al. framework to produce results that violate conventional expectations suggests that it should be used with caution. C1 USN,CTR TRAINING SYST,ORLANDO,FL 32826.

In the present report, we examine the effect of accumulation of liposome encapsulated hemoglobin on the structure of reticuloendothelial organs following administration of liposome encapsulated bovine hemoglobin in the normovolemic rat. We have also examined the administration of the liposome vehicle, tetrameric bovine hemoglobin, and liposome encapsulated bovine hemoglobin that had been lyophilized with 300 mM trehalose and rehydrated just before injection. Following injection into the tail vein, rats were sacrificed and liver, spleen, kidney, and lung harvested at 2 h, 24 h, 1 week, and 2 weeks for analysis. Gross pathologic findings of animals injected with liposome encapsulated hemoglobin showed statistically significant splenomegaly with a waxy parenchymal pallor at early time points. Microscopic findings indicate that the liver and spleen are principally involved with liposome encapsulated hemoglobin removal over the course of 24 h with transient cytoplasmic vacuolization in tissue resident phagocytes as evidenced by both light and electron microscopic examination. Presence of liposome encapsulated hemoglobin in these vacuoles was confirmed by oil red O and prussian blue stains. Splenic weight was observed to decline after 24 h but still remained significant above sham-treated controls at 2 weeks and could be correlated with increased hematopoietic activity. Other findings only in animals injected with lyophilized liposome encapsulated hemoglobin included transient loss of laminae rara in the basal lamina, podocyte fusion in the kidney, and small pulmonary infarcts in the lung over the course of 24 h. This latter finding may be associated with trapping of large particles or agglutinated liposome encapsulated hemoglobin. These data indicate that the administration of liposome encapsulated hemoglobin causes transient changes in the organs of the reticuloendothelial system. (C) 1995 John Wiley and Sons, Inc.

The instrument employs an argon ion laser (514 nm) to launch light into a long-clad fiber and measures the fluorescence produced by an immunofluorescent complex formed in the evanescent wave region. This sensing area is a short section (12.5 cm) at the end of the optical fiber from which the cladding has been removed and in which the silica core has been tapered. Capture antibodies, which bind to F1 antigen, were immobilized on the core surface to form the basis of the sandwich fluoroimmunoassay. The ability. to detect bound F1 antigen was provided by adding tetramethylrhodamine-labeled anti-plague antibody to form fluorescent complexes. The evanescent wave has a limited penetration depth (<1 lambda), which restricts detection of the fluorescent complexes bound to the fiber's surface. The direct correlation between the F1 antigen concentration and the signal provided an effective method for sample quantitation. This method achieved a high level of accuracy for determining F1 antigen concentrations from 50 to 400 ng/ml in phosphate-buffered saline, serum, plasma, and whole blood, with a 5-ng/ml limit of detection. Subsequent blind studies, which included serum samples from patients, yielded results in good agreement with measurements by enzyme-linked immunosorbent assay. A major advantage of the fiber optic biosensor is that results-can be generated within minutes while isolating the user from hazardous samples. These factors favor development of this biosensor into a facile and rapid diagnostic device. C1 GEOCENTERS INC,FT WASHINGTON,MD 20744. USA,MED RES INST INFECT DIS,DIV APPL RES,FT DETRICK,MD 21702.

The hybridization is a continuous switch and operates on each characteristic field separately. The explicit scheme is a version of the second-order Godunov scheme; the implicit method is only first-order accurate in time but leads to a block tridiagonal matrix inversion for efficiency and is unconditionally stable for the case of linear advection. The methodology is described for the cases of linear advection, for nonlinear scalar problems, and for gas dynamics. An important element of our work is the use of a modified Engquist-Osher flux function in place of the Godunov flux. Several numerical results are presented to demonstrate the properties of the method, especially stable numerical shocks at very high CFL numbers and second-order accurate steady states.

For a Th cell to produce sufficient IL-2 to allow autocrine-driven clonal expansion, there is a requirement for so-called ''costimulatory'' or ''accessory'' signals in addition to TCR ligation by Ag/MHC. Although the first signal delivered by TCR ligation has been well characterized, information regarding the biochemical nature of second signals is limited. In the present report, using a newly generated mAb specific for CD28, signal transduction by the CD28 receptor has been studied in mouse splenic T cells. When freshly isolated splenic T cells were assessed, cross-linking of CD28 by mAb did not induce increases in intracellular calcium concentration whereas TCR cross-linking was able to induce calcium mobilization. In contrast, when T cells were activated by phorbol ester treatment or by in vitro culture, CD28 ligation was able to induce calcium mobilization in 60 to 70% of splenic T cells. Unexpectedly, the CD28-induced calcium;response was mainly limited to T cells of the CD4(+) subset, whereas both CD4(+) and CD8(+) T cell subsets showed increases in [Ca2+](i) of similar magnitude after CD3 epsilon ligation. The temporal nature of the CD28-induced signal was also different from TCR-induced calcium mobilization. CD28-induced signals were delayed in onset and sustained in duration in contrast to TCR signals that had short latency and brief duration. Differential expression of CD28 on the surface of activated CD4(+) or CD8(+) T cells did not appear to account for the differences in signal transduction between the two T cell subsets. The preferential responsiveness of the CD4(+) T cell population to CD28-induced signaling was also observed in downstream events such as the induction of IL-2R, CD69 expression, and in cellular proliferation. These results indicate that the costimulatory signal delivered by CD28 may have fundamentally different biochemical properties in CD4 and CD8 T cell subsets, and therefore the functional role of CD28 may differ in these T cell subsets.

The present studies were designed to test whether the loss of tolerance to myelin basic protein (MBP) requires costimulation by members of the B7 receptor family. CTLA-4Ig, a fusion protein ligand for B7-1 and B7-2, was used to assess the role of B7-mediated costimulation in chronic relapsing experimental allergic encephalomyelitis (EAE) induced by the transfer of MBP specific T cell lines. In adoptively transferred EAE, administering CTLA-4Ig to donor mice or during in vitro activation of MBP specific-T cells resulted in diminution of clinical disease. The presence of CTLA-4Ig during both the immunization and in vitro activation stages was most effective in preventing clinical signs of disease. This diminution in clinical disease was paralleled by a decreased proliferative response and reduced production of IL-2 and IL-4, but not IFN-gamma, after antigenic stimulation of encephalitogenic T cells in vitro. In contrast, CTLA-4Ig treatment of recipient animals after the transfer of MBP-activated T cells affected neither disease course nor severity. These results indicate that additional costimulatory pathways may be involved in established EAE, or that some cells are independent of costimulation or, alternatively, that CTLA-4Ig does not enter brain parenchyma in therapeutic concentrations. Thus, we conclude that costimulation provided by B7 molecules plays a major role in the development of encephalitogenic T cells and in the establishment of chronic relapsing EAE, a prototypic CD4(+) T cell-mediated autoimmune disease.

In an effort to identify pathogenic EAggEC isolates, four groups of 5 volunteers were fed 1 of 4 different EAggEC strains, each at a dose of 10(10) cfu, Strain 042 caused diarrhea in 3 of 5 adults; 3 other EAggEC isolates (17-2, 34b, and JM221) failed to elicit diarrhea. A gene encoding enterotoxin EAST1 was found in strains 042 and 17-2 but not 34b or JM221; a 108-kDa cytotoxin was expressed in all 4 isolates. All 4 isolates showed a modest degree of gentamicin protection in HEp-2 cells. 17-2, 34b, and JM221 expressed the fimbrial antigen AAF/I; 042 did not express this fimbria as determined by immunogold electron microscopy and genetic probe hybridization.

Four separate bands associated with the O-H stretching vibration dominate the absorption spectra of these glasses between 4000 and 1500 cm(-1). Two of these bands are attributed to hydroxyl with vibrational frequencies perturbed by hydrogen bonds between the hydroxyl and adjacent non-bridging oxygens. The other two bands arise from the vibration of 'free' hydroxyl ions associated with either germanium or gallium tetrahedra. Hydrogen-bonded hydroxyl absorptions are present in the spectra of all compositions. This observation leads to a modification of the previously proposed structural model for these glasses. In addition, the relative concentration of various types of hydroxyl is correlated to the changes in structure associated with changes in composition. Specifically, the fraction of hydrogen-bonded hydroxyl increases at the expense of 'free' hydroxyl when the number of non-bridging oxygens in the glass increases.

The effects of the interactions between worms of both sexes of the 2 species on development and egg laying were evaluated in vivo by infecting hamsters with cercariae from Biomphalaria alexandrina and Bulinus truncatus snails infected with single miracidia. In hamsters with unisex infections, male worms of both species were small. Schistosoma mansoni females were stunted and partially mature but did not contain eggs. Schistosoma haematobium females, though stunted, sometimes contained and laid small eggs, which were deposited in the liver, but few of which contained motile embryos. This suggests that unisexual infection with S. haematobium female worms produces a risk for liver damage due to egg deposition in tissues. Both S. mansoni and S. haematobium females that mated with males of the heterologous species were significantly larger than females from unisexual infections; they were sexually mature and possessed eggs in the uterus. The eggs in the liver homogenates of cross-specific infected hamsters contained fully developed miracidia that hatched in filtered pond water.

In the first experiment, the fate of percutaneous challenge infections with Se-75-labeled cercariae was evaluated by autoradiography of tissue squashes and hepatic portal perfusion. For both strains of parasite, migration from skin to lungs was delayed but not reduced in immunized mice relative to controls, with immune elimination taking place at some point after migration to the lungs. In a second experiment, resistance to the Mill Hill strain of S. mansoni was compared in mice challenged by percutaneous infection with cercariae and by intravenous injection with lung schistosomula. Both types of challenge were shown to be vulnerable to immune elimination. We conclude that under the conditions employed in this study, there is no significant difference between the NMRI and Mill Hill strains of S. mansoni in the patterns of migration and elimination, with most or all elimination in both control and immunized mice taking place after migration from the skin.

Stability of the structure is one of the major concerns in the design process. This research focuses on analytical and experimental studies of an unbalanced composite sandwich beam subjected to a compressive axial load. The failure load (i.e., peak load) and failure mode of each skin material and tile sandwich construction were measured at the laboratory. An analytical model was developed for predicting the failure load of the unbalanced and asymmetric sandwich composite configuration, including the transverse shear energy of the core material. The experimental data agreed wry well with analytical prediction. Postbuckling failure, as well as residual strength after initial failure, were also studied.

The explanatory variables are solute parameters, R(2) an excess molar refraction, pi(2)(H) the solute dipolarity-polarizability, Sigma alpha(2)(H) and Sigma beta(2)(H) the solute hydrogen bond acidity and basicity and log L(16) where L(16) is the K-value on hexadecane. The coefficients in the above equation then characterize the particular phase, the most important being s the phase dipolarity-polarizability, a the phase basicity, b the phase acidity and I a constant that reflects a combination of cavity effects and general dispersion interactions and is related to the ability of the phase to distinguish between homologues. Derivation of the constants for the various phases provides a quantitative method for the analysis of the selectivity of phases for particular solute analytes and a term-by-term investigation of log K values shows exactly the solubility interactions that lead to sorption of a solute by a phase and hence to the analytical determination of the solute through chemical microsensors.

In the ellipsometric spectra of Zn1-xCoxSe films with 0.04 less than or equal to x<0.1 grown on GaAs substrates, sharp distortions of the interference patterns below the fundamental band gap were observed at energies between 1.6 similar to 1.9 eV. To understand this, we calculated multilayer model (air/Zn1-xCoxSe/GaAs). The dielectric function of the film is approximated by using harmonic oscillator model with two oscillators with transition energies at 1.67 and 1.83 eV. The calculated pseudodielectric function shows the same behavior as our measured pseudodielectric response, resulting that our da:a shows the clear existence of the absorptions due to intra d to d transitions of Co2+ ions under a tetrahedral crystal field.

The droplets, containing approximate to 2 x 10(-7) M concentration of Rhodamine 6G dye as a fluorophor, were generated as a monodisperse stream with continuously variable sizes from approximate to 6.5 to 6.6 mu m in radius. This range of droplet size permitted Ar+ laser pump radiation (514.5 nm) to become resonant with the droplet for both TE and TM modes of orders 1-4. Emission spectra from 530 to 585 nm were obtained for each of the resolved input resonances. The results clearly show higher relative intensities in emission modes that have the same mode order as the pump radiation resonance. Convolution integrals of radial profiles of the input and output modes are consistent with the general pattern of observed spectral intensities. C1 USN,RES LAB,DIV OPT SCI,WASHINGTON,DC 20375.

A total of 15 patients with 16 bladder transitional cell carcinomas and one patient with renal pelvic transitional cell carcinoma were evaluated prospectively with transabdominal color Doppler ultrasonography. The presence or absence of visible vascularity and the resistive index were correlated with tumor size, cytologic grade, and tumor stage. Statistical analysis was performed with Fisher's exact test. Seven (41%) of 17 tumors had visible vascularity: five (45%) of 11 high-grade transitional cell carcinomas were vascular, whereas two (33%) of six low-grade transitional cell carcinomas were vascular (P = 1.00). Three of five (60%) of the invasive lesions were vascular, but the vascularity was not predictive of tumor stage (P = 0.593). The vascular high-grade tumors tended to have more numerous and larger visible vessels than the vascular low-grade lesions. No tumor smaller then 23 mm was vascular, but the size of the tumor was not predictive of the vascularity (P = 0.1172). The resistive index was measurable in six tumors, but it was not predictive of grade or stage. Color Doppler ultrasonography is not helpful clinically in the evaluation of transitional cell carcinoma as tumor grade, stage, and size are not related to vascularity. Larger and high-grade tumors are more likely to be vascular and have larger visible vessels, but this was of no predictive value. C1 USN MED CTR,DEPT RADIOL,SAN DIEGO,CA 92134.

Epinephrine, the standard drug for vasoconstriction, has some Limitations due to potential dose-related cardiac and local toxic effects. The authors examined the minimal effective epinephrine concentration required for maximal cutaneous vasoconstriction in the human subject so as to limit potential dose-related side effects, Ln a randomized, double-blinded prospective study, 23 patients undergoing head and neck surgical procedures under general anesthesia were enrolled to quantify the effect of subdermal infiltration of 1% lidocaine with epinephrine at varying concentrations on local cutaneous bloodflow utilizing laser Doppler flowmetry, A comparison of the onset of vasoconstriction and magnitude of diminished bloodflow was made for several commonly used concentrations of epinephrine, with 1% lidocaine and normal saline serving as controls. There were no significant differences (P>.05) between epinephrine concentrations of 1:400,000, 1:200,000, 1:100,000, and 1:50,000 when examining onset and magnitude of vasoconstriction.

We indicate how this basic result can be derived from chaotic, interacting Hamiltonian systems which include densely packed polymer molecules. Recent quasielastic neutron scattering experiments and molecular dynamics simulations are discussed and the results are shown to support this result as well. An application of the coupling model to find how the viscoelasticity of a polymer depends on the chemical structure of the monomer through the coupling parameter of the local segmental motion is given to illustrate the utility of the model.

The recombinant plasmid appeared to be a circular episome in the host cells. Reverse transcription PCR showed that the PyCSP was trans-spliced by the addition of the 39-bp spliced leader of L. enriettii at its 5' end. The transfectant expressed a protein in a pattern similar to that found in the sporozoite itself. Immunofluorescence and immunoelectron microscopy indicated that PyCSP was abundantly expressed on the surface of the parasite. Mice immunized with the transfectant produced antibodies to sporozoites, had a delay in onset of parasitemia after challenge, and 4 of 22 (18%) were completely protected. The protected mice had cytotoxic T lymphocytes against the PyCSP. Immunization with recombinant vaccinia, Salmonella typhimurium, and pseudorabies virus expressing the PyCSP induces excellent immune responses, but has not been shown to protect against challenge. Thus, the modest protection found in these initial studies represents a step forward. After further work Leishmania may prove to be an important live vector vaccine system for induction of protective immune responses. C1 USN,MED RES INST,DIV PATHOBIOL,BETHESDA,MD 20889.

During these track changes, which are generally not well forecast, the cyclones are often accompanied by a separate comma-shaped area of gale-force winds and deep convection along the eastern periphery. This monsoon surge is distinct from the tropical cyclone. Synoptic analyses often reveal a building anticyclone to the east or southeast of the monsoon gyre. The hypothesis that the sudden track change is initiated by a binary interaction of the tropical cyclone and monsoon gyre is tested with a nondivergent barotropic model. Tropical cyclone-scale vortices with initial positions within the eastern semicircle of a larger monsoon gyre-scale vortex initially coalesce with the monsoon gyre and then exhibit sudden poleward track changes that are similar to the observations. During the coalescence phase, the large and relatively weak monsoon gyre undergoes a beta-induced dispersion in which nonlinear vorticity advection also plays an important role. This dispersion process produces strong ridging to the east and southeast of the coalesced tropical cyclone and monsoon gyre. An intermediate region of high winds that resembles the observed monsoon surge develops between the monsoon gyre and the peripheral ridging. A southerly steering develops across the coalescing tropical cyclone and monsoon gyre and causes the poleward acceleration. Key features of the simulated streamfunction and isotach patterns associated with the sudden track changes are substantiated with synoptic analyses of observed cases with similar track changes. Thus, it is concluded that the tropical cyclone-monsoon gyre interactions are a likely explanation for monsoon surge track changes and that the observed phenomena may be explained to first order by conservation of absolute vorticity on a beta plane.

The power spectra of the analysis agree closely with observations, but the forecast shows larger differences. The westward-propagating horizontal structure is well represented in both the analysis and the forecast, although they tend to produce a higher spatial coherency than that determined from the observations. The observed vertical structure, with a very small low-level tilt in the eastern region (east of 140 degrees E) and an eastward tilt throughout the troposphere in the western region (west of 140 degrees E),contrasts sharply with the typical summer structure observed previously. This contrast, when compared with the seasonal difference in vertical mean wind shear due to the East Asian monsoons, is consistent with the theoretical effect of the vertical shear on tropical wave structure. The east-west variation of the vertical structure is reproduced by the analysis, but the forecast structure has a weaker vertical organization over areas where a well-organized structure is observed, and a stronger organization to the west where it is not observed. It appears that the model's dynamics produces a downstream propagation that results in a wave structure that is partially artificial. C1 FLEET NUMER METEOROL & OCEANOG CTR,MONTEREY,CA.

Molecular denaturation, coupled with a net increase in entropy, accounts for the net negative Delta G and frequent irreversible nature of surface adsorption. Real world complications arising from this fundamental biophysical problem include marine fouling of ships' hulls, the progressive obstruction of sewer pipes, inactivated pharmaceutical agents and adverse biological reactions to implanted medical devices. Using self-assembled nanocrystalline particulates with polyhydroxyloligomeric surface films, much of this surface-induced denaturation appeals to have been arrested. Beginning with preformed carbon ceramic nanoparticles and self-assembled calcium-phosphate dihydrate particles (colloidal precipitation) to which glassy carbohydrates are then allowed to adsorb as a nanometer thick surface coating, a molecular carrier is formed. The carbohydrate coating functions as a dehydroprotectant and stabilizes subsequently non-covalently bound immobilized members of biochemically reactive surface pairs. The final synthetic product consists of three layers. The core is comprised of the ceramic, the second layer is the dehydroprotectant polyhydroxyloligomer adhesive, and the surface layer is the biochemically reactive molecule for which delivery is desired. Many of the physical properties of this enabling system have been characterized in vitro and in animal models. By all measures at present, the favorable physical properties and biological behavior of the molecular transportation assembly point to an exciting new interdisciplinary are a of technology development in materials science, chemistry and biology.

Army policy specifies strict constraints on unit rotations, such as the length of a unit's stay in any location, the number of units moving at any time, and the allowable replacements for any moving unit. Scheduling rotations manually in accordance with these rules, as is currently practiced, is extremely difficult and time consuming. This article presents an integer programming model that finds feasible, minimum-cost schedules for the Pakistan Army's desired planning horizons. The model also ensures that the units are positioned at the end of the planning horizon so that feasible schedules exist for future planners. The model is implemented with commercially available optimization software. Schedules are obtained for realistic test problems in less than an hour on a personal computer.

The searcher must choose one cell in which to search in each time period. The set of cells available for search depends upon the cell chosen in the last time period. The problem is to find a search path, i.e., a sequence of search cells, that either maximizes the probability of detection or minimizes the mean number of time periods required for detection. The search problem is modelled as a partially observable Markov decision process and several approximate solutions procedures are proposed. (C) 1995 John Wiley & Sons, Inc.

Consequently, the widely-available Mie code for a sphere can be used to calculate the light scattering by a dielectric spheroid at large size-parameter. The method is tested numerically and shown to work well for a spheroid when its minimum radius of curvature is about the size of the wavelength of light or greater and for scattering angle up to 30 degrees.

A valence force potential is used, consisting of central interactions between nearest neighbors and bond-bending interactions centered at the Si4+, Be2+, and Al3+ ions. The force constants are determined by fitting the calculated frequencies to the results of a complete study of the Raman spectra of a large single crystal. The calculated frequencies are in reasonable agreement with experiment, permitting unambiguous assignment of normal modes to the observed spectral lines. In several cases, the resulting interpretation of spectral features differs significantly from those published previously. Considerable mixing of Al and Be motions with those of the ring is found for the Raman-active modes near 750 cm(-1) and above 850 cm(-1),respectively. The normal modes and frequencies of the hypothetical isolated ring with C-6h symmetry are determined by neglecting all interactions between the rings and the surrounding Be and Al atoms. This identification of normal modes characteristic of six-membered silicate rings and the effect of the environment on these modes may prove useful in the interpretation of infrared and Raman spectra of amorphous silicates.

The purpose of this study was to determine the effect of ultrasound on forearm, skin, and muscle blood flow. Subjects. Twenty volunteers without known vascular problems (10 male, 10 female) participated. Methods. All subjects received a treatment of continuous-wave ultrasound to the anterior forearm at a dosage of 1.5 W/cm(2) for a duration of 5 minutes. The contralateral forearm served as the control and received identical treatment, except the ultrasound output remained at zero. Forearm blood flow was measured using venous occlusion plethysmography, and skin blood flow was measured using cutaneous laser-Doppler flowmetry before and after ultrasound administration, with the difference being muscle blood flow. Results. No differences between the control arm and the ultrasound-treated arm were found for muscle, skin, and forearm blood flow. Conclusion and Discussion. These results suggest that administration of continuous-wave ultrasound at the prescribed dosage had no effect on skeletal muscle blood flow for up to 30 minutes posttreatment. Thus, muscle hyperemia is probably not the primary mechansim responsible for the clinical benefits seen following the use of ultrasound as a therapeutic modality.

While previous reports on the results of the NEOSH Survey have discussed the occurrence, frequency, and effects of sexual harassment in the Navy [A.L. Culbertson, P. Rosenfeld, and C. E. Newell (1993) Sexual Harassment in the Active-Duty Navy: Findings from the Navy-Wide Survey (TR-94-2), San Diego, CA: Navy Personnel Research and Development Center], this study examines whether victims of sexual harassment differ in their perceptions of equal opportunity (EO) climate from those who have not been harassed. Data from the 1991 NEOSH Survey were reanalyzed. Sixty-seven percent of the women officers were White, 25% African-American, and 18% Hispanic. Of the women enlisted, 52% were White, 31% African-American, and 18% Hispanic.

In addition, specific organizational consequences of sexual harassment were identified. C1 USN,CTR PERSONNEL RES & DEV,WOMEN & MULTICULTURAL RES OFF,CODE 01E,SAN DIEGO,CA 92152.

At various incubation times (e.g. 3, 6, 12, 24 h), the ICAM-1 expression was enhanced by lipopolysaccharide (LPS, or endotoxin) from one ng/ml to 100 mu g/mL with maximal enhancement at .1-1 mu g/mL. The kinetics at 1 mu g/mL LPS showed that the maximum ICAM-1 expression occurred at 24 h. The LPS-induced ICAM-1 expression was not inhibited by the neutralizing rabbit polyclonal antibodies against human IL-1 alpha r, 1L-1 beta, and TNF alpha, either alone or in combination. This indicated that the mechanism of this induced expression was not an autocrine effect mediated by the LPS-induced IL-1 or TNF alpha. The LPS-induced cell surface ICAM-I exhibited a polarized distribution shown in immunoelectron micrographs with higher density on the luminal surface. DNA synthesis activity of HUVEC was, contrary to the ICAM-1 expression, suppressed by LPS. Immunocytochemical studies indicated that ICAM-1 was not uniformly expressed in the culture, i.e., some cells expressed more surface ICAM-1 than others, and some of the ICAM-1-expressing cells had an uneven patchy distribution of this antigen. Combined immunocytochemical and [H-3]thymidine incorporation studies showed that cells with strong ICAM-1 expression had little DNA synthesis activity, while those with little ICAM-1 expression synthesized DNA actively. ICAM-1 on endothelial cells serves as an anchor for the leukocytes in cell-cell adhesion. Its differential expression among the cells in the endothelial population may explain the localized and scattered sites of leukocytes sticking to endothelium observed at wound sites and during extravasation.

Based on single-dose caffeine studies, a similar dose-response effect has been hypothesized on performance, alertness and mood during sleep loss. The present study compared the effects of repeated versus single-dose administration of caffeine and varying amounts of sleep taken prior to sleep loss on performance, mood and physiological measures during 2 nights and days of sleep loss. A total of 140 normal, young adult males participated at one of two study sites. Ninety-eight subjects at one site were randomly assigned to one of four nap conditions (0, 2, 4 or 8 hours) and 42 subjects at the second site were assigned to one of four caffeine conditions. After a normal baseline night of sleep and morning baseline tests of performance, mood and nap latency, subjects in the nap groups returned to bed at noon, 1600 hours, 1800 hours or not at all. Bedtimes were varied so that all naps ended at 2000 hours. Subjects in the caffeine groups received either a single 400-mg dose of caffeine at 0130 hours each night or repeated doses of 150 or 300 mg every 6 hours starting at 0130 hours on the Ist night of sleep loss. A placebo control group (no nap and placebo administered every 6 hours on the repeated caffeine schedule) was run at both sites. Subjects remained awake and followed the same schedule of computer-administered performance tests, mood scales, multiple sleep latency test observations and meals/breaks for 52 hours before being allowed a recovery night of sleep at their normal sleep time. Results are consistent with previous findings and suggest that performance, mood and alertness are directly proportional to prophylactic nap length. Furthermore, an 8-hour nap is superior in maintaining performance, mood and alertness to either single or repeated caffeine administrations. Naps, in general, provided longer and less graded changes in performance, mood and alertness than did caffeine, which displayed peak effectiveness and loss of effect within about 6 hours. Shorter prophylactic naps and small repetitive doses of caffeine, however, did maintain performance, mood and alertness during sleep loss significantly better than no naps or large single doses of caffeine. Neither nap nor caffeine conditions could preserve performance, mood and alertness near baseline levels beyond 24 hours, after which levels approached those of placebo.

Accurate positions for excited states of nitrogen on the carbon site have been determined and are in excellent agreement with effective mass theory using values for longitudinal and transverse effective masses from cyclotron resonance results. Photoluminescence spectra in the two-electron satellite region are consistent with the transmission results and give the nitrogen 2s state binding energy. Two other donors are observed with low concentrations: an effective mass donor at 47.7 meV and avery shallow donor with a binding energy of 34 meV. Zeeman splitting of the 2p(+/-) excited states with B parallel to[111] for all three donors is in good agreement with the previously measured transverse effective mass. Valley-orbit splitting of the nitrogen ground state is observed but no valley-orbit splitting can be seen for the effective mass donor as expected. We suggest that the very shallow donor has a repulsive core (negative chemical shift) and inverted ordering with the Is(A(1)) ground state above the 1s(E) ground state similar to lithium in silicon.

Intractable hiccups can be an indication of a serious underlying disease process and should be investigated. To demonstrate the evaluation of intractable singultus, we describe a patient who had unsuccessful outpatient therapy for persistent hiccups and who was subsequently found to have gastroesophageal reflux (GER). Efforts to determine the cause of the hiccups were negative except for endoscopically proven GER. On follow-up visits, antisingultus medications were withdrawn without return of hiccups, and repeat endoscopy showed substantial healing of the esophagitis. We conclude that GER may be underestimated as a cause of hiccups. C1 USN HOSP,DEPT FAMILY PRACTICE,CHARLESTON,SC. USN HOSP,DEPT INTERNAL MED,CHARLESTON,SC.

The quadruple cell structure has D-2h symmetry which can be distorted to C-2h geometry under B-1g vibration. Such a structure allows the interconversion of different spin angular momenta into paired spins similar to Cooper pairs. It also provides vibronic interactions that lower the energy of the ground state. For electron (hole) pairing, we construct the running wave Bloch sums consisting of linear combination of bonding/antibonding geminals (instead of one-electron atomic orbitals) in these quadruple cells. For ''bond'' movement we construct the Bloch sums consisting of linear combination of ''Covalon'' waves in quadruple cells related to the movement of conjugate (alternating) bonds. In both cases the pair-wise charge (hole/electron) transfer is coupled with antisymmetric vibrations under a double-well potential related to Peierls distortion. The vibronic mixing of different running bonds with different antisymmetric vibrations at various distances, accounts for the different long-range order of charge transfer. Our formulations represent an alternative view of BCS theory, Bisoliton theory and Resonanting Valence Bond theory by using a quantum chemical, position-space approach to a more tight binding situation.

Vortex Reynolds number is defined as the ratio of circulation around the vortex structure to the fluid viscosity. The vortex structure of the outer region was modeled and a full numerical simulation was then conducted using a high-order spectral method. A unit domain of the outer region of a turbulent boundary layer was assumed to be composed of essentially three elements: a wall, a Blasius mean shear, and an elliptic vortex inclined at 45 degrees to the flow direction. The laminar base-flow Reynolds number is roughly in the same range as that of a turbulent boundary layer based on eddy viscosity, and the vortex-core diameter based on the boundary-layer thickness is nearly the same as the maximum mixing length in a turbulent boundary layer. The computational box size, namely, 500, 150, and 250 wall units in the streamwise, surface-normal, and spanwise directions, respectively, is approximately the same as the measured quasi-periodic spacings of the near-wall turbulence-producing events in a turbulent boundary layer. The effects of vortex Reynolds number and the signs of the circulation on the moments of turbulence were examined. The signs mimic the ejection and sweep types of organized motions of a turbulent boundary layer. A vortex Reynolds number of 200 describes the turbulence moments in the outer layer reasonably well.

The ability to detect evanescent fields from above demonstrates that near-field microscopy of the liquid/air interface is possible. The evanescent decays are compared with predicted decay lengths and with the decay above a quartz prism. Gravity waves are seen in all three liquids, with wave amplitudes inversely proportional to the viscosity of the liquid. These waves interfere with but do not preclude near-field approach to the interface.

For this reason, angiography and cystoscopy are rarely employed in the evaluation. The evaluation of the child should proceed methodically and rest firmly on a well-taken history and results of physical examination. The microscopic examination of the urinary sediment is the cornerstone of the evaluation process and can itself suggest the origin of the hematuria. Red cell casts, if present, indicate glomerulonephritis and obviate further urologic evaluation. Genitourinary imaging should be tailored to each clinical situation.

A convenience sample of 30 healthy men and women were randomly assigned to one of three treatment groups, which designated the order in which the interventions were administered. Instrumentation included a Novametrix Model 840 transcutaneous monitor, a Dinamap BP monitor, a BoMed NCCOM3 cardiovascular monitor, and YSI 44008 thermistors. Analysis of ambient temperature at baseline revealed that the room was significantly cooler for men than for women. Analysis of covariance revealed no significant difference between men and women, except at baseline. The mean PtcO2 for each activity, as well as the post-activity period, was significantly higher than at baseline. There was a significant interaction between gender and activity for PtcO2 and PtcCO2. For both men and women, the mean changes in PtcCO2 were statistically significant but clinically insignificant. The order in which interventions were administered did not have a significant effect on either PtcO2 or PtcCO2. The results suggest that the physical activity associated with nursing interventions may significantly improve oxygen levels in the skin by stimulating overall cutaneous circulation.

Exploiting this relationship, we present in this paper a new approach to the quantum mechanics of an electron in a uniform magnetic field B, in the plane (the Landau electron) and on the a-torus in the presence of a periodic potential V whose periodicity is that of an N x N lattice (the Peierls electron). For the Landau electron, G is the Euclidean group E(2) whose central extensions arise from the Heisenberg Lie group central extensions, determined by B, of the translation subgroup. The state space is a unitary representation of the direct product of two such groups corresponding to B and -B and the Hamiltonian is a unique element of the universal enveloping algebra of the centrally-extended E(2). The complete quantum theory of the Landau electron follows directly, For the Peierls electron, lattice translation-invariance is possible only if the flux per unit cell Phi takes rational values with denominator N. The state space is a unitary representation of the direct product of a finite Heisenberg group, which is a central extension of the translation group, and a Heisenberg Lie group, both characterised by Phi. The following new results are rigorous consequences. In the empty lattice limit V = 0, the energy spectrum is the Landau spectrum with degeneracy equal to the total flux through the sample. As V moves away from zero, every Landau level splits into N Phi discrete sublevels, each of degeneracy N. More generally, for V not equal 0 of any strength and (periodic) form, and B such that Phi, is nonintegral, every point in the spectrum has multiplicity N. The degeneracy is thus proportional to the linear size rather than the area of the sample. Throughout the paper, vector potentials and gauges are dispensed with and many misconceptions thereby removed. C1 USN,RES LAB,WASHINGTON,DC 20375.

Six paleomagnetic poles are determined, one from three seamounts sharing a ridge, and five from isolated seamounts. Two poles fall near a continental Late Cretaceous South American pole and are assumed to be of Late Cretaceous age. Another seamount has a preliminary Ar-40/Ar-39 age of 62 +/- 4 Ma. We check this age and estimate the ages of other seamounts by rotating their poles into North American coordinates and comparing them with North American paleomagnetic reference poles. These ages and the characteristic magnetic polarities of all Bahia Seamounts are used to test hotspot models of formation of the seamount group. The northern and central Bahia Seamount chains could have formed from a single hotspot. The southern Bahia chain may require a second hotspot. The two postulated hotspots were probably concurrent and separated by 150 to 200 km. The paleomagnetic poles trace out a smooth curve from the Late Cretaceous poles to a pole that is indistinguishable from the spin axis, which we estimate as having an Early Eocene age. The pole ages remain preliminary until better age dates are found and rocks are recovered from more seamounts. RP BRYAN, PC (reprint author), USN,RES LAB,CODE 7420,WASHINGTON,DC 20375, USA.

It was found that these sterols eliminate the interdigitation of the alkyl chains in the DHPC sub-gel and gel-state bilayers while stabilizing the ripple gel-state at the expense of the gel-state bilayer phase. The ripple-ripple phase transition previously observed for dipalmitoylphosphatidylcholine in the presence of low molar concentrations of sterols (Wolfe et al. (1992) Phys. Rev. Lett. 68, 1085-1088) was also observed for similar DHPC-sterol mixtures. In addition, we show the first evidence that the presence of 5 alpha-cholestane-3 beta,5,6 beta-triol will cause the lipid mixtures to continue to adopt a ripple mesophase structure even after the DHPC alkyl chain becomes disordered.

Attenuation of image intensity modulation in the azimuthal direction implies that ocean wave spectra derived from such images also will not be accurate. Real aperture radar cross-section modulation by long ocean waves is normally attributed to two principal sources, tilt modulation and hydrodynamic modulation. In ocean radar images both of these modulation sources are significantly attenuated in the azimuthal direction. Therefore, complete two-dimensional k-space wave spectra derived from microwave data often are quite different than physical ocean spectra. This paper uses fully-polarimetric radar measurements of ocean backscatter to identify a new source of backscatter modulation that is strongest in the azimuthal direction. This modulation source has potential for augmenting tilt and hydrodynamic modulation sources in the azimuthal direction where their weakness causes poor wave visibility. The predicted improvement in the measurement of ocean wave spectra using an optimized polarization is investigated by means of a RAR ocean imaging model. Fully-polarimetric, and conventional, radar spectrometers are proposed which are specifically optimized to sense wave-tilts in the azimuthal direction.

PIB has perhaps the most compact and symmetric monomer chemical structure among amorphous polymers, which leads to the expectation that it has a smaller capacity for intermolecular coupling and a lower degree of cooperativity of the local segmental motion. In the framework of the coupling model this expectation for PIB implies that it has a smaller coupling parameter which is sufficient to explain its various distinct viscoelastic properties as demonstrated in previous works. Up to now there is no direct determination of the coupling parameter for local segmental motion of PIB to confirm that it is indeed smaller compared with other amorphous polymers. Dielectric spectroscopy is inapplicable to PIB because the monomer has a negligible dipole moment. Mechanical spectroscopic measurements performed on PIB have not yielded unambiguous results because of the difficulty of isolating the contribution of the local segmental motion from the experimental data. In this work we have resorted to photon correlation spectroscopy and successfully obtained the correlation function of the local segmental motion of PIB which can be well fit by a Kohlrausch stretched exponential function. The stretch exponent, beta, has the value of 0.56. The coupling parameter, given by 1 - beta, has the value of 0.44 for PIB which is indeed significantly smaller compared with other amorphous polymers and consistent with the value we deduced indirectly from other experiments.

However, late-stage monotypic B cells have been detected in the blood. This work analyzes the effects of clinical treatment on late stage CD19(+) B cells present in 752 blood samples from 152 MM patients. MM patients have 2 to 8 times as many circulating CD19(+) cells as do normal donors. Analysis of the Ig heavy chain (IgH) gene rearrangements using polymerase chain reaction indicates that the CD19(+) population includes cells sharing the same clonotypic CDR3 region as is detected in the BM plasma cells, for patients analyzed during chemotherapy or in relapse. They are also monotypic as defined by their cytoplasmic or surface expression of Ig kappa- or lambda light chain. The light chain restriction is the same as that of the BM plasma cells. Individual patients observed over 1- to 2-year periods exhibit considerable variation in the number of B cells present in blood; this number does not correlate with the concentration of serum monoclonal Ig. The monoclonal blood CD19(+) cells are not eliminated by any of the chemotherapy regimens analyzed and remain at high levels during transient remissions. Patients in the progressive phase of disease or in relapse have significantly higher numbers of B cells than do patients in transient remission or untreated patients. During periods when the quantity of blood B cells approaches normal, phenotypically their quality is highly abnormal, with physical and phenotypic heterogeneity. Most B cells express CD45R0, a high density of CD38, and CD56 characteristic of late-stage B or pre-plasma cells. CD38(hi) blood B cells had a cyclical presence. We conclude that monoclonal B cells in the blood of myeloma patient populations include drug-resistant reservoirs of clonotypic cells that may underlie relapse.

The data consist of temperature and salinity measurements made by a ship-based conductivity-temperature-depth (CTD) instrument and by a drifting SALARGOS buoy. These data were collected in the autumn and early winter of 1988-1989 in the northern Barents Sea, mostly in ice-covered conditions and then across the marginal ice zone (MIZ). The data show that relatively warm, salty water of Atlantic origin is modified by air cooling and ice melting to produce lighter water that has properties identical to (lower) halocline water found in the Arctic Ocean. This occurs mostly at the MIZ and to a lesser degree within the ice pack itself. At the MIZ the halocline water subducts underneath the lighter meltwater that resides directly under the ice pack; geostrophic velocity calculations indicate that it then turns eastward and flows toward the Kara Sea, in keeping with previous chemical tracer analyses. A rough calculation reveals that the amount of halocline water formed in this way in the Barents Sea and Fram Strait is 30-50% of that formed by ice growth in eastern Arctic polynyas.

In this report we show a very simple but elegant technique that protects optically clear granular (micron-size) free-standing PS from laser damage. This technique involves encapsulating PS grains in a polymethyl methacrylate thin film. We measure the absorption coefficient of these films as a function of PS concentration. We also study the photoluminescence (PI,) and Raman active phonon modes in these films by a micro-Raman/luminescence instrument. The PL peak is also monitored as a function of incident power. A blue shift of the PL peak is observed that is attributed to saturation of low-lying electronic levels associated with Si nanocrystallites.

Inclusion of the quadrupole-ionic lattice interaction in the model leads to large differences between the diffraction of H-2 in its j = 0 rotational state and diffraction of j = 1 H-2. For j = 1 H-2 large probabilities are obtained for changes of the magnetic rotational quantum number m(j). It should be possible to verify some of our results by diffraction experiments employing cold beams of para-H-2 and normal-H-2. C1 USN,RES LAB,DIV CHEM,WASHINGTON,DC 20375.

For the GRO OSSE detector, we also present the sum of the data for this and earlier observations. The overall spectrum is very well described as a power law with an energy spectral index of similar to 1 absorbed at low energies plus a strong Compton reflection component, typical for Seyfert 1 galaxies. The low energy absorption can be well described by a sum of a neutral column density of similar to 3 x 10(21) cm(-2), most of which is associated with the edge-on galactic disk of IC 4329A, plus an edgelike feature at similar to 700 eV; this feature implies either complex absorption (due to additional ionized material, or due to partial covering), or a soft excess. The data only weakly constrain the presence of a high-energy cutoff in the underlying power law; they are compatible with an exponential cutoff at any energy E(c) greater than or similar to 100 keV. The relative steepness of the OSSE data, with the power-law energy index of 1.6 +/- 0.2, can be accounted for entirely by the contribution of the high-energy tail of the reflection component when E(c) --> infinity. (We find that the definite cutoff at an energy E(c) similar to 130 keV suggested in the recently published analysis of the OSSE data for this object is due to a data reduction error.) Including nonsimultaneous Ginga observations with 2 keV fluxes matching well that of ROSAT gives us likely broadband X-ray/gamma-ray spectra of the object from similar to 0.1 keV up to several hundred keV. Joint spectral analysis of the data sets from the three instruments gives results similar to those from ROSAT/OSSE only, except that the cutoff energy is now constrained to be at 250 keV less than or similar to E(c) less than or similar to 1700 keV. The constraint on E(c) markedly distinguishes this object from NGC 4151, where E(c) was lower, similar to 50 keV; this has implications for emission models for AGNs as well as for their contribution to the X-ray background. We also report the ROSAT spectrum of the companion object to the Seyfert galaxy, the elliptical galaxy IC 4329 located similar to 3' away. Its spectrum is well described by an optically thin thermal plasma with kT = 0.9 keV, with a 0.1-2 keV flux of 8 x 10(-13) ergs cm(-2) s(-1), corresponding to a luminosity of similar to 8 x 10(41) ergs s(-1).

In both data sets, the flux density was relatively high, and the intrinsic source size small compared to the scattering, ideal conditions for a detailed study of interstellar scattering. We find that the scattering disk is anisotropic, with an axial ratio 1.31 +/- 0.02 along position angle 52.degrees 0 +/- 1.degrees 5. This is the first unambiguous measurement of anisotropic scattering in the interstellar medium. We also find a significant break in the phase structure function, the first measurement of a break in any source. The data exclude a steep turbulent spectrum, but are consistent with a shallow turbulent spectrum with an inner scale of 300 km, with a net uncertainty of similar to 50%. We tentatively identify the scattering plasma with the H II region DR 11, for which we estimate a visual extinction of 4 mag, and an emission measure toward Cyg X-3 of 6000 cm(-6) pc. We make the case that DR 11 is part of a shed of H II regions centered on the Cyg OB2 association (which is similar to 1.8 kpc distant) that is 2 degrees (60 pc) in radius and expanding at 10 km s(-1). Our inner scale is consistent with that expected for an H II region, and the amount of scattering is consistent with the emission measure. We discuss how the anisotropy can be used to confirm the identification with DR 11 and to distinguish between different models of turbulence by comparison with measurements of the polarization of starlight along the line of sight.

Of the five low-luminosity X-ray sources toward omega Cen which were first identified with the Einstein imaging proportional counter (IPC) (Hertz and Grindlay 1983a, b), two are detected in the Einstein HRI observation: IPC sources A and D. These detections provide source positions accurate to 3''4''; the positions are confirmed in a ROSAT HRI observation reported here. Using CCD photometry and spectroscopy, we have identified both sources as foreground dwarf M stars with emission fines (dMe). The chance projection of two dMe stars within similar to 13' of the center of omega Cen is not extraordinary, given the space density of these stellar coronal X-ray sources. We discuss the possible nature of the three as yet unidentified IPC sources toward omega Cen, and consider the constraints that the Einstein observations place on the total population of X-ray sources in this cluster. The integrated luminosity from faint X-ray sources in omega Cen appears to be low relative to both the old open cluster M67 and the post-core-collapse globular, NGC 6397.

There are several remarkable aspects to the data. The core of the H II region is composed of numerous emission clumps with peak brightness temperatures of approximate to 15,000 K. Extremely wide line profiles, 250 km s(-1) FWZP, are observed from the core, indicating substantial mass motions of the ionized gas. The H66 alpha spectral profiles exhibit multiple emission peaks. The peaks and shapes of the H66 alpha recombination line profiles vary significantly as a function of position within the core region. The H66 alpha line-to-continuum ratios also vary considerably within the core region. A thin strip midway between the northern and southern core continuum components is the region of largest electron density. The center of this dense, disk-like structure most likely delineates the position of the exciting star. We present a model for NGC 7358 IRS 1 that involves a stellar wind outflow and photoevaporation of nearby clumpy neutral material. This results in a clumpy continuum appearance and a complicated set of broad- and multiple-peaked spectral profiles. Ionized gas escapes the core region in an outflow to the north and south. Toward the south the outflow is partially limited by neutral material, producing a southern, spherical continuum component which exhibits much narrower H66 alpha line profiles than the core region.

We find that the index of the pulsation is l = 1 with a high degree of confidence, the first unambiguous determination of l for a pulsation of a ZZ Ceti star. We also find that log g and T-eff are tightly correlated for model atmospheres that fit the data, such that at log g = 7.5 the temperature is 11,750 K and at log g = 8.0 the temperature is 12,375 K. Adopting log g = 7.97 +/- 0.06 from published observations of the optical spectrum of G117-B15A, the correlation yields T-eff = 12,375 +/- 125 K. This temperature is free of flux calibration errors and should be substantially more reliable than temperatures derived fro IUE spectra. Since G117-B15A is thought to he dose to the blue edge of the ZZ Ceti instability strip, this low temperature also implies a low temperature for the blue edge. Using pulsation models calculated by Fontaine et al. (1992) and Bradley (1994), we find that the mass of the hydrogen layer in G117-B15A lies between 1.0 x 10(-6) M. (for k = 1) and 8 x 10(-5) M. (for k = 2). This range of masses is (barely) consistent with the masses predicted by recent models for the ejection of planetary nebulae, (8-13) x 10(-5) M.. The mass is too large to be consistent with models invoking thin hydrogen layers to explain the spectral evolution of white dwarfs. C1 UNIV TEXAS, MCDONALD OBSERV, AUSTIN, TX 78712 USA.

During the first 80 days, the spectra exhibited continuum emission from thermal bremsstrahlung (free-free radiation) with prominent recombination line emission from hydrogen, helium, nitrogen, and oxygen. The measured FWHM of these recombination lines suggests that the initial velocity of the ejecta was approximate to 2400-3400 km s(-1). We estimate from the hydrogen recombination line ratios that the density of the ionized shell at this epoch was approximate to 10(9) cm(-3), with an effective electron temperature of approximate to 5 x 10(3) K. As the temporal evolution of the ejecta progressed, the hydrogen and helium lines diminished in intensity, and coronal lines of aluminum, calcium, magnesium, neon, and sulfur appeared by approximate to day 80. The coronal line emission phase persisted for over 400 days. During this epoch, no significant dust formation occurred. We find that the ejecta of V1974 Cyg were overabundant in aluminum with respect to silicon by a factor of approximate to 5 and in magnesium with respect to silicon by a factor of greater than or equal to 3 relative to the solar photosphere. Comparison of our observed overabundances with recent model predictions of elemental synthesis in ONeMg outbursts suggests that the accreted envelope on V1974 Cyg was close to solar composition and that the precursor ONeMg white dwarf had a mass of approximate to 1 M..

Over the years there have been numerous reports of so-called ''below-cutoff'' Fe-group cosmic rays, with momentum below the minimum required for a fully ionized particle to reach Earth's inner magnetosphere. These reports comprised just a few tens of ions, but stimulated much speculation about partially ionized Galactic cosmic ray, suggesting a nearby source of Galactic cosmic rays. In this Letter we compare these previous reports to new observations of below-cutoff Fe-group ions from passive track detectors exposed for nearly 6 years in low-Earth orbit aboard NASA's Long Duration Exposure Facility (LDEF) satellite. The LDEF fluxes are only a few percent of the previously reported fluxes. This comparison suggests tha the flux of below-cutoff ions must be out of phase with the observed solar-cycle variation of other (nonsolar) cosmic-ray sources and/or must strongly increase with decreasing altitude in low-Earth orbit. Both of these features are inconsistent with the notion of partially ionized Galactic cosmic rays as the source of the observed below-cuttoff ions. C1 GEORGE MASON UNIV,INST CSI,FAIRFAX,VA 22030.

Our sample contains three classes of objects with markedly different spectra: radio-quiet Seyfert 1's and 2's, and radio-loud Seyfert 1's. The average radio-quiet Seyfert 1 spectrum is well-fitted by a power law continuum with the energy spectral index alpha almost-equal-to 0.9, a Compton reflection component corresponding to a approximately 2pi covering solid angle, and ionized absorption. There is a high-energy cutoff in the incident power law continuum: the e-folding energy is E(c) almost-equal-to 0.6(-0.3)+0.8 MeV. The simplest model that describes this spectrum is Comptonization in a relativistic optically-thin thermal corona above the surface of an accretion disk. Radio-quiet Seyfert 2's show strong neutral absorption, and there is an indication that their X-ray power laws are intrinsically harder, although the Seyfert 1 spectrum with alpha = 0.9 and strong reflection cannot be ruled out by the data. Finally, the radio-loud Seyfert spectrum has alpha almost-equal-to 0.7, moderate neutral absorption, E(c) = 0.4(-0.2)+0.7 MeV, and no or little Compton reflection. This is incompatible with the radio-quiet Seyfert 1 spectrum, and probably indicating that the X-rays are beamed away from the accretion disk in these objects. The average spectra of Seyferts integrated over redshift with a power-law evolution can explain the hard X-ray spectrum of the cosmic background. The hump at approximately 30 keV in that spectrum is due to the dominant contribution of Seyfert 2's. C1 USN,RES LAB,EO HULBURT CTR SPACE RES,WASHINGTON,DC 20375.

Exposure of hair to cocaine at 1 mu g/ml for 5 min is sufficient to contaminate hair, yet decontamination is a very slow process. Using externally contaminated hair, a number of decontamination procedures were attempted, and none removed all the contamination. The percentage of external contamination removed depended on the hair type, with thick black hair being the most resistant to decontamination. Hair treated by dying incorporated externally applied drugs differently, depending on the hair type. Thick black hair became more absorbent whereas thin brown hair became less absorbent, Kinetic wash criteria are evaluated for their ability/inability to determine if hair has been contaminated from external sources. A theoretical framework for the incorporation and removal of drugs from hair is discussed, and the hypothesis that inaccessible domains exist in hair which trap drugs is critically examined. The results presented in this paper strongly suggest that much more information on the decontamination of hair and the differentiation of exogenously and endogenously incorporated drugs is needed before hair analysis can be employed in most forensic applications. We propose that the radioactive tracer methods discussed herein are well suited for evaluating any new decontamination or extraction technique. C1 USN,RES LAB,WASHINGTON,DC 20375.

It is, however, similar in size to the recently discovered Kuiper-belt objects(6)-a population of objects with orbits beyond Neptune, which are a possible source of short-period comets. This has led to the conjecture that Chiron is related to these objects, but its chaotic orbit has brought it much closer to the Sun(7). Here we report observations of a recent stellar occultation by Chiron which permit the identification of several features associated with Chiron's coma. The observation of discrete, jet-like features provides evidence that the coma material originates from just a few, small active areas, rather than from uniform sublimation, and that the particles in at least one of these features have radii greater than 0.25 mu m. The observations also suggest the presence of material in the plane of Chiron's orbit and are consistent with a gravitationally bound coma, Finally, the present data, and those from a previous occultation(8), constrain the radius of Chiron to lie between 83 and 156 km.

The voltammograms cover the potential range: +0.3 to -1.3 V (measured against an Ag/AgCl/KCl (sat) reference) and indicate that the partial current due to the Pd2+ ion reduction is diffusion limited at slow scan rates. Except for the significant increase in cathodic currents due to D2O reduction at ca. -0.25 V which occurs on a freshly generated Pd surface, the shapes of the voltammograms marginally differ from those recorded in the absence of Pd2+ ions in the electrolyte phase. A discussion of the dynamics of the interphase is presented. C1 US DOE,WASHINGTON,DC 20585. RP SZPAK, S (reprint author), USN,CTR CONTROL & OCEAN SURVEILLANCE,DIV RDT&E,SAN DIEGO,CA 92152, USA.

As the emission in this energy region is most likely electron bremsstrahlung, this implies that the source electron spectrum also turns up below a few MeV. If the spatial extent of these low energy electrons is similar to that of the Galactic cosmic rays, a power of about 4x10(41) erg s(-1) is required to maintain the electrons against energy losses to the interstellar medium. This power exceeds the power supplied to the nuclear cosmic rays by about an order of magnitude. We propose that these electrons provide the ionization and heating required to maintain the equilibrium of the warm (10(4) K) ionized component of the interstellar medium.

We show that the Comptonized gamma-ray spectra can exhibit spectral breaks Delta alpha much greater than 0.5 due to the effects of Coulomb losses of relativistic electrons with the background thermal plasma of the outflowing material.

Previous measurements of the all-particle spectrum in this energy range have been obtained by a, mix of active and passive techniques. One of these measurements (Grigorov, 1989) shows a departure from a simple power law and scatter in the remaining measurements do not rule out such a feature. To check if there is a break in the power-law spectrum, we have undertaken to make a measurement of the ail-particle spectrum over this energy range with a single instrument. We will report preliminary results from the Thin Ionization Calorimeter (TIG) experiment which was flown for 76 hours in the summer of 1994.

In this scenario, the interplanetary source population is considered to be the local plasma encountered by the shock[1], e.g. the solar wind on field lines which are well connected to the observer. The recent high-energy (E approximate to 200 - 600 MeV/nuc) SEP Fe mean charge state ([Q] = 14.2 +/- 1.4) result[2] during September-October 1989 is inconsistent with a typical solar wind charge state distribution, and indicates that [Q] is essentially unchanged from approximate to 1 MeV/nuc[3, 4].

The analysis gives evidence that only one short-term modulation with period 0.0813 days was obviously present in the 1993 I light curve of the nova. On the other hand the analysis shows that two short-term modulations with periods 0.0813 and 0.085 days (whose values are close to 2-day aliases of one another) are present in the 1994 V and I light curves of Nova V1974 Cygni. The 0.0813-day period is stable and we interpret it as the orbital period of the system, while the 0.085-day period is decreasing and may be the spin period of the white dwarf component of the system.

Early active experiment payloads, CHARGE-2 and SPEAR-1, observed enhanced currents from/to the vehicles during unplanned attitude thruster firings. The follow-on CHARGE-2B and SPEAR-3 payloads directly measured the changes to the vehicle potential caused by both planned argon and unplanned nitrogen releases. The gas releases from positively charged CHARGE-2B consistently reduced the potential to 20-50 V, whereas the gas releases from negatively charged SPEAR-3 brought the potential to between -200 and -500 V. The difference in grounding levels for positively and negatively charged payloads suggests that the gas responsible for grounding is near the vehicle, within a small fraction of the sheath size.

An OO-DNC prototype viewer capable of importing, displaying and editing DNC feature data both from relational-format and from object-format files was developed using the Smalltalk language. The differences in performance between the relational import and the object import were then compared across several DNC coverages. The results indicate a significant increase in performance when adopting the OO paradigm; specifically the OO-DNC viewer imported feature data from object-format files from 6 to 15 times faster than from the relational-format files. It should be noted that these figures are NOT the result of comparing a commercial object-oriented database managment system (ODBMS) against a commercial relational database management system (RDBMS), but rather the result of reading both relational-oriented and object-oriented data file formats using an object-oriented program written in Smalltalk. Nevertheless, we feel these results indicate a significant functionality and performance improvement can be obtained by using an OO framework for the data and software.

Only a partial response was noted with magnesium oxide replacement. Treatment with the potassium-sparing diuretic amiloride led to a further rise in the serum magnesium level, a decrease in the fractional excretion of magnesium and improvement in her symptoms. This case demonstrates an effective treatment for idiopathic renal magnesium wasting. RP BUNDY, JT (reprint author), USN,MED CTR,DIV NEPHROL,620 JOHN PAUL JONES CIRCLE,PORTSMOUTH,VA 23708, USA.

Mice given 140 plaque-forming units (PFU) of virus (58% survival) gradually decreased food and water intake to nearly zero over 6 days; survivors then slowly increased intakes. Declines in these behaviors were parallel to decreases in body temperature and general locomotor activity and were associated with elevated activities of interleukin-6 (IL-6), tumor necrosis factor-alpha, and interferons in lung lavage fluid. Circulating levels of these cytokines were not increased. After 55,000 PFU of virus (100% mortality), food and water intake fell to near zero within 48 h, temperature and locomotor activity decreased significantly, and activities of IL-1 and IL-6 were elevated in lung lavage fluid. These data show that cytokine activities in the lungs are elevated in a time frame that supports the hypothesis that cytokines could mediate behavioral and physiological changes in mice during acute influenza infections.

Study subjects included 200 recruits, 500 shipboard personnel deployed for six months to South America, West Africa, and the Mediterranean, and 300 ground troops deployed for five months to Saudi Arabia. Among all 1,000 subjects, 247 (25%) were seropositive for H. pylori IgG antibody by an enzyme-linked immunosorbent assay; 24% of new recruits and 25% of troops who had been on active duty for a mean of four years. The prevalence of H. pylori antibody was higher among subjects who were older, nonwhite, foreign-born, and seropositive for antibody to hepatitis A virus. Among the 601 initially seronegative subjects evaluated before and after a 5-6-month deployment outside the United States, five seroconverted, for a rate of infection of 1.9% per person-year of exposure. As found in other populations in developed countries, these data indicate that among U.S. military personnel a large proportion of H. pylori infections occur before adulthood and infection is related to demographic factors. These preliminary findings also suggest that deployed U.S. military personnel may be at increased risk of H. pylori infection compared with adult populations in developed countries either from exposure in developing countries or from crowding.

This paper reports two new studies that extend that research. These studies use survey data from 142 part-time MBA students and 408 project engineers, respectively. Results identify three interpretive styles that explain a significant proportion of variance in self-reported stress symptoms. Deficiency focusing involves a tendency to focus on what is wrong or can go wrong. Necessitating involves thinking in terms of what one ''needs'' to do. Low skill recognition involves a tendency not to attribute successes to one's competence. These interpretive styles appear consistent with constructs proposed by Beck, Ellis, and Seligman in clinical populations. The styles are asserted to increase stress by skewing subjects' primary appraisal process toward higher perceived threat. Possible interventions for modifying these interpretive styles are discussed.

Given the spacing in between the slits, the (Bragg) angular diffraction pattern generated by the grating can be predicted by the method of physical optics (acoustics), and can be numerically evaluated for gratings with either uniformly or irregularly spaced slits. It has been already established that the diffraction patterns of planar gratings can be used (i.e. Brill, D. & Gaunaurd, G. C., J. Acoust, Sec. Amer., 93 (1993) 71-9) to model the far-field scattering patterns produced by thin, cylindrical, elastic shells in water that have many reinforcing ribs. Varying the size and slit spacing (i.e. the ribs), the diffraction pattern becomes distorted, and for very irregularly spaced cases the distortion is substantially asymmetric and noticeable. In some instances it is also possible to I elate the resulting diffraction pattern - which can be generated by computer for any conceivable configuration - to the grating size and the regular or irregular type of separations in between its slits. This serves to identify the type of grating that generated the pattern, a finding of importance in the area of underwater acoustic target recognition. A number of graphs are shown to illustrate these points. C1 USN,CTR SURFACE WARFARE,WHITE OAK LAB,SILVER SPRING,MD 20903.

Results suggest that multiple radical species are formed during UV photolysis of DMN, perdeutero-DMN-d(6), and N-15-labeled DMN. Proton ENDOR spectra are consistent with assignment of a cation radical (CH3)(2)NNO2+. as the major DMN radical species. Proton hyperfine coupling anisotropy, which is observed from the ENDOR spectra, is attributed to inequivalence of the two DMN methyl groups. C1 AMER UNIV BEIRUT,DEPT PHYS,BEIRUT,LEBANON.

An essential feature of the theory is the inclusion of the temperature dependence of the density of the solvent. The theory of free volume for liquids is incorporated into the reaction field model to account for this temperature dependence. Comparison of the theory with previously reported measurements indicates the sensitivity of the Xe-129 chemical shift to the free volume of liquids. Incorporation of free volume improves the agreement between measurement and theory for branched alkane solvents, and resolves the origin of the 62 ppm intercept in the plot of reaction field as a function of Xe-129 chemical shift for the n-alkanes.

We report Xe-129 NMR experiments at 9.4 T that provide such information for xenon adsorbed onto the hydroxylated surface of a number of microporous silica samples at 77 K. A convenient design for these cryogenic experiments is described. Dynamics of surface-adsorbed xenon atoms on the time scale of seconds can be observed by Xe-129 NMR hole-burning experiments; much slower dynamics occurring over hours and days are evidenced from changes with time of the Xe-129 NMR chemical shifts. The peak maxima occur in the region ca. 180-316 ppm, considerably downfield of Xe-129 shifts previously reported on surfaces at higher temperatures, and closer to the shift of xenon bulk solid (316.4 +/- 1 ppm). The Xe-129 spin-lattice relaxation times T-1 range over five orders of magnitude; possible explanations for both nonexponential relaxation behavior and extremely short T-1 values (35 ms) are discussed. Preliminary Xe-131 and H-1 NMR results are presented, as well as a method for greatly increasing the sensitivity of Xe-129 NMR detection at low temperatures by using closely-spaced trains of rf pulses.

Emphasis is placed on studying the response of the system after the initial loss of stability of straight line motion. Center manifold reduction and integral averaging methods are used in order to study bifurcations to periodic solutions and stability of the resulting limit cycles. Numerical integrations are used to confirm the theoretical results and to establish regions of asymptotic stability. The methods used in this work demonstrate the significance of nonlinear terms in assessing the response of the system.

With both techniques the relative sensitivity is low for the main transition usually employed, i.e., the 2s photoemission line in XPS and the KLL transition in electron-excited AES. With XPS, the A1 X-ray-excited Mg KLL peak has a relative intensity that is greater than the 2s transition, but not with Mg radiation. The peak-to-peak height of the electron-excited AES peak can vary with the chemical state of Mg. Also, in some instances overlapping peaks can cause problems. In this study Mg was implanted into metal foils at various levels. Depth profiles were obtained with both XPS and AES, and the instrument-based quantitative analysis computer routines were used with slight modifications. It was found that each technique had its own set of advantages, and both approaches gave roughly comparable profiles. The estimated maximum amounts were below those anticipated from the implant conditions. As expected with XPS, chemical effects could easily be determined. However, a relative sensitivity factor was needed to use the X-ray-excited KLL Auger transition. With AES certain low-level contaminants were more easily detected and monitored. Overall, the XPS profiles appeared to offer better results in most respects for these systems.

Adsorption of O2 on the clean and B-adsorbed surfaces was also studied. Cleaning the (0001) surface by annealing in a flux of Si vapor gives a (3 x 3) structure which converts to (square-root 3 x square-root 3)R30-degrees upon further annealing in vacuum. The (3 x 3) consists of an ordered layer of Si chemisorbed on the Si termination layer, while the (square-root 3 x square-root 3)R30-degrees involves an ordered arrangement of Si vacanies. A (1 x 1) structure is observed for the clean C-face. Adsorption of B on the (3 x 3) Si-face eliminates the reconstruction, and further annealing produces a complicated superstructure. Stronger interaction occurs on the (square-root 3 x square-root 3)R30-degrees Si-face leading to an incommensurately ordered (1 x 1) layer loosely termed ''Si boride'' due to the substantial changes in SiL2,3VV and BKLL Auger lineshapes. On the C-face, a disordered B layer forms. On B-free surfaces, room-temperature chemisorption of O2 is slower on the (1 x 1) C-face than on the (3 x 3) Si-face, but the rates of O uptake become comparable with increasing coverage as chemisorption gives way to oxidation. For the (square-root 3 x square-root 3)R30-degrees Si-face, chemisorption is rapid, but oxidation very slow. For all three surfaces, adsorbed B suppresses chemisorption of O2 but has little or no effect on oxidation. RP BERMUDEZ, VM (reprint author), USN, RES LAB, WASHINGTON, DC 20375 USA.

Both the chromogenic and turbidimetric methods require significant dilution of the LEH preparation before accurate measurement can be made. We have tested the levels of endotoxin in LEH solutions using these methods and measured LEH, liposome, and hemoglobin samples spiked with known amounts of endotoxin. A comparison of the three methods shows that the absolute value of endotoxin measured in LEH by the three methods can vary significantly. However, within any one assay the spiked amount of endotoxin in the sample can be accurately measured. The accuracy of these methods may also be complicated by the binding of endotoxin to LEH. This was evident by mixing free endotoxin with LEH followed by centrifugation to separate the LEH. Biological activity of endotoxin bound to LEH was measured by exposure to RAW264.7 followed by the expression of tumor necrosis factor. C1 GEOCENTERS INC,FT WASHINGTON,MD 20744.

Empty liposomes (L) caused less decrease of CH50/ml, whereas free Hb had no effect on C activity. The LEH- and L-induced increases in C consumption were unlikely a consequence of endotoxin (LPS) contamination, as spiking of rat serum with LPS caused reduction in C only at levels significantly higher than those detectable in LEH or L.

The link to this frame has traditionally been made by the observation of these objects and of stars in absolute transit circle programs. The zero points of the link are applied to quasi-absolute catalogs, and these are combined with the absolute catalogs to define the fundamental system. The individual positions and motions of the fundamental stars are then strengthened by incorporating differential catalogs reduced to the fundamental system. The system can be extended to higher densities and fainter magnitudes by further systematic reduction and combination of differential catalogs. The fundamental system itself, however, can only be extended through a planned series of observations resulting in absolute stellar positions over a range of epochs. A new fundamental catalog being compiled at the U.S. Naval Observatory is discussed and compared with the existing standard, the FK5.

First, the volume of space out to which luminosities may be determined to the accuracy of the best, very-nearby stars will be increased greatly. For the relatively rare field Population II stars, this will lead to the first accurate empirical calibrations of the main sequence at the low mass end, for comparison with globular clusters of various metallicities. Parallaxes at 1 kpc or farther will be adequate to help in the discovery or confirmation of the rare carbon dwarfs - main sequence stars with carbon-rich atmospheres. For cool white dwarfs, luminosities accurate to a few per cent or better will identify unresolved binaries, and objects of unusually high and low mass. For our most numerous solar neighbors, the M dwarfs and especially those near the stellar mass limit, accurate luminosities can help in the determinations of the chemical composition and age distributions.

The use of retroreflectors or transmitters located on solar system objects may be the most promising technique. However, if these accurate observations can be achieved, this provides the opportunity for significant improvements in the orbits of the planets, satellites, and minor planets, and will provide, or require, improvements in the models for the tidal interactions, secular accelerations, and masses. The observations will provide a test, or improvement, of the ties between radar, optical, and radio observations. This should provide an opportunity for improving the reductions of pulsar timing observations and improve our determination of the solar system reference system.

The extragalactic, or radio, reference frame will be the basic frame. Achieving milli to microarcsecond accuracies at optical wavelengths will reduce the disparity between optical, radar, and radio reference frame determinations. Thus, the relationships and identifications of common sources should be much more accurate. Another significant change should be the ability to determine distances, and thus space motions on a three-dimensional basis, rather than the current two-dimensional basis of proper motions. Improvements in ephemerides provide the opportunity to investigate the difference between atomic and dynamical time, the relationship between the dynamical and extragalactic reference frame and the values of precession and nutation. Also, the relationships between the bright and faint optical catalogs, the infrared, and extragalactic reference frames should be better determined.

The data collected in this campaign are from GRO, ROSAT, Voyager 2, IUE, HST, ESO, CTIO, SAAO and the VLA. Great care has been taken in disentangling the genuine AGN continuous emission from other contributions: depending on the waveband, the latter might be (i) unrelated contaminating sources in cases where the instrument field of view is large, (ii) components within which the AGN is embedded, such as the stellar bulge population which accounts for a significant fraction of the optical continuum, and free-bound and FeII blends which contribute to the ultraviolet flux. After correction for these other contributions, the continuous emission of the isolated AGN appears to be rather flat (i.e., approximately equal energy per unit logarithmic frequency) from soft gamma-ray to infrared wavelengths. At high energies (0.1 MeV to 0.1 keV), the AGN continuum can be fitted by a power law F-upsilon proportional to upsilon(-alpha) with a spectral index alpha approximate to 1. At longer wavelengths, two excesses above this power law (''bumps'') appear: in the ultraviolet, the classical big blue bump, which can be interpreted as thermal emission from the accretion disc surrounding a massive black hole, and in the infrared a second bump which can be ascribed to thermal emission from dust in the vicinity of the AGN, heated by ultraviolet radiation from the central source. By fitting accretion-disc models to the observed AGN spectral energy distribution, we find values for the accretion disc innermost temperature, accretion rate, and black hole mass, with some differences that depend on whether or not we extrapolate the high-energy power law up to infrared wavelengths. A fit to the LR bump above the extended alpha = 1 power law suggests the presence of a dust component covering the region from a distance r approximate to 80 light days (hot grains at a temperature T approximate to 1500 K) to r approximate to 60 light years (cool grains at T approximate to 200 K). The total mass of dust is around 60 M(.). C1 OHIO STATE UNIV, DEPT ASTRON, COLUMBUS, OH 43210 USA. ESA, IUE OBSERV, E-28080 MADRID, SPAIN.

Most previous interpretations have involved intrinsic variations of a very compact source requiring extremely high brightness temperatures or Doppler factors. An analysis is presented of simultaneous recordings of flux density at wavelengths 2cm, 3.6cm, 6cm, 11cm and 20cm. The variations are characterized by a time scale that increases from 2.5 hrs at 2cm to 18 hrs at 20cm. A high degree of correlation with no time offset is found between the slowly-varying components of the variations at 3.6cm, 6cm and 11cm. Whereas intrinsic models predict variations with a delay that increases with wavelength, an ISS model predicts the correlation as observed, under the condition that the source diameter increases with wavelength and is greater than the scattered diameter. A detailed ISS model for the scintillation is proposed, including a specific source structure and a 200 pc distance to the scattering region. The brightness temperature is estimated to be 6.10(12) K, consistent with studies of superluminal sources. Though polarization variations are only approximately consistent with the model, the conclusion is that the major fraction of the variance in the cm wavelength flux density of 0917+624 is due to ISS. Whereas the present study does not rule out additional intrinsic variations on times of a less than a day, it demonstrates that very compact sources exhibit rapid ISS, which must be included for a proper interpretation.

The probability that the association of strong EGRET sources with supernova remnants is due to chance alignment is found to be less than or similar to 1/2200. Three of the most convincing associations are radio-bright, nearby shell remnants and a fourth is associated with a plerion. We examine possible gamma-ray production mechanisms and conclude that pion production and decay from high-energy protons interacting with the remnant gas could produce the gamma rays. The energetics of this process are in accord with theories of cosmic ray production through supernova shock acceleration. The identification of pi(0)-decay features in the gamma-ray spectra of supernova remnants would support this interpretation.

We observed a single eclipse egress with ROSAT. The time of this egress is consistent with the apparent increase in P(orb) previously reported on the basis of EXOSAT and Ginga observations. Standard analysis, in which O-C (observed minus calculated) timing residuals are examined for deviations from a constant period, implicitly assume that the only uncertainty in each residual is measurement error and that these errors are independent. We argue that the variable eclipse durations and profiles observed in EXO 0748-676 imply that there is an additional source of uncertainty in timing measurements, that this uncertainty is intrinsic to the binary system, and that it is correlated from observation to observation with a variance which increases as a function of the number of binary cycles between observations. This intrinsic variability gives rise to spurious trends in O-C residuals which are misinterpreted as changes in the orbital period. We describe several statistical tests which can be used to test for the presence of intrinsic variability. We apply those statistical tests which are suitable to the EXO 0748-676 observations. The apparent changes in the orbital period of EXO 0748-676 can be completely accounted for by intrinsic variability with an rms variability of approximately 0.35 s per orbital cycle. The variability appears to be correlated from cycle-to-cycle on time-scales of less than 1 yr. We suggest that the intrinsic variability is related to slow changes in either the source's X-ray luminosity or the structure of the companion star's atmosphere. We note that several other X-ray binaries and cataclysmic variables have previously reported orbital period changes which may also be due to intrinsic variability rather than orbital period evolution.

The observations were made 1994 February 8-17, immediately prior to the peak of a giant outburst. The phase averaged spectrum is complex and cannot be described by a single-component model. We find that structure in the spectrum above 100 keV can best be modeled by an absorption feature near 110 keV, which we interpret as the signature of cyclotron resonant scattering. Because of OSSE's 45 keV threshold, we are unable to make a definitive statement on the presence of a 55 keV absorption line; however, we can conclude that if this line does exist, it must have a smaller optical depth than the line at 110 keV. A first harmonic (=fundamental) cyclotron resonance at 110 keV corresponds to a magnetic field strength at the surface of the neutron star of similar to 1 x 10(13) G (similar to 5 x 10(12) G if the first harmonic is at 55 keV).

Expressions for the absorption, scattering and extinction coefficients, single scattering albedo and asymmetry factor are obtained. The integration over the droplet size distribution is done analytically and the resulting expressions are found to be sufficiently accurate (within 3% for the tenth order polynomial approximation in the IR region) and computationally fast. When only the first two terms are kept in the polynomial expansions, the resulting expressions reduce to the Slingo parameterization of the radiative properties of clouds in the shortwave region. It is shown that this parameterization is more accurate than approximations based on geometrical optics and anomalous diffraction theory. C1 DALHOUSIE UNIV,DEPT OCEANOG,HALIFAX,NS B3H 3J5,CANADA.

Theodore Roosevelt (CVN 71) participated in a voluntary survey on tobacco-related matters, The survey queried participants on their tobacco-use history, subjective exposure to environmental tobacco smoke (ETS), and attitudes related to smoking policy prior to the cessation of all smoking activities aboard ship. Of the 2,221 crewmembers who participated (74% response rate), 36% classified themselves as current cigarette smokers. Nonsmokers estimated their general exposure to ETS between ''low'' to ''moderate.'' Of all participants, 57% were in favor of the current restricted smoking policy, including 18% of currently smoking personnel. Follow-up research is being con ducted to assess the long-term impact of the no-smoking policy on changes in attitudes regarding policy, tobacco use rates, and ETS exposure.

The TMV coat protein is a well-characterized and abundant self-assembling polymer previously shown to be a highly immunogenic carrier. Selected B-cell epitopes were either inserted into the surface loop region of the TMV coat protein or fused to the C terminus using the leaky stop signal derived from the replicase protein reading frame. Tobacco plants systemically infected with each of these constructs contained high titers of genetically stable recombinant virus, enabling purification of the chimeric particles ire high yield. Symptoms induced in tobacco ranged from a normal mosaic pattern similar to that induced by the parental U1 strain to a unique bright yellow mosaic. As measured by quantitative ELISA against synthetic peptide standards, wild type TMV coat protein and fusion protein synthesized by the leaky stop mechanism coassembled into virus particles at the predicted ratio of similar to 20:1. Recombinant plant viruses have the potential to meet the need for scalable and cost effective production of subunit vaccines that can be easily stored and administered.

Specific activity as a function of concentration of purified enzyme could be fit to an equation describing the dissociation of a compound into two components. An association constant, K-a, was determined in this way to be 39.4 +/- 8.7 mug protein/ml. The concentration of the enzyme affected its kinetic parameters: a tenfold decrease in enzyme concentration caused a reduction of the V-max and K-m(NAD) values to 45% and 58%, respectively, of the values for undiluted (0.64 mg/ml) enzyme. Diaphorase (NAD-dependent reduction of benzyl viologen) specific activity of the hydrogenase was unaffected by dilution. The extent of dilution-induced activity loss was dependent on pH, with greater activity loss observed at higher pH values. The substrate NAD prevented loss of specific activity due to dilution, while the product NADH did not. Specific activity loss due to dilution was reversed with the addition of the cofactor FMN. Dilution of the hydrogenase caused an increase in the enzyme's specific flavin fluorescence. These results suggest that dilution of the soluble hydrogenase of Alcaligenes eutrophus causes dissociation of the cofactor FMN, and this activity loss should be taken into account as an important factor governing hydrogenase activity and kinetic properties.

This method involves the use of patterned self-assembled monolayers. The quantity of purple membrane adsorbed to glass terminated by various self-assembled monolayers was measured using angle resolved X-ray photoelectron spectroscopy. It was determined that purple membrane adsorbs to unmodified glass and amine-terminated glass surfaces. Hydrocarbon- and fluorocarbon-terminated glass inhibit the adsorption of purple membrane. To demonstrate a potential patterning methodology, an amine-terminated self-assembled monolayer (SAM) was photochemically substituted for a hydrocarbon-terminated SAM using UV radiation. Future work will involve the use of UV radiation in conjunction with a lithographic mask so that specific PM adsorption sites can be defined on a substrate.

Rapid increases in population and urban migration, various ecological changes, increasing poverty, and a rise in international travel have contributed to the worldwide vulnerability of human populations to the emergence, recurrence or spread of infectious diseases. In the rapidly growing city of Djibouti in East Africa, public health priorities have been altered during the last 10 years by diseases which were unknown or under control until the early 1980s, These diseases, including malaria, AIDS, tuberculosis, dengue fever and cholera, are consuming considerable resources, This article on Djibouti illustrates the epidemiological changes in the region, Besides the specific ecological and behavioural changes, which accompany a rapid population growth, poverty seems to be a major cause for the emergence and recurrence of infectious diseases.

The individual hollow concentric graphitic nanotubes that comprise these fibers can be visualized as constructed from rolled-up single sheets of graphite. We discuss the use of helical symmetry for the electronic structure of these nanotubes, and the resulting trends we observe in both band gap and strain energy versus nanotube radius, using both empirical and first-principles techniques. With potential electronic and structural applications, these materials appear to be appropriate synthetic targets for the current decade.

The average Young's modulus is found to be 680 GPa, with some indication that the intrinsic modulus of CVD carbon may be much higher. This value exceeds those found by earlier high-strain, static-pulling methods. Although the amplitude of vibrational response for these fibers is linear in the driving force, the shape of the frequency response deviates from Lorentzian as the amplitude increases. This behavior has not been previously reported in other materials. Possible explanations based on the fibers' microstructure are discussed C1 USN,RES LAB,MAT PHYS BRANCH,WASHINGTON,DC 20375.

Concentrations of DDT, DDE, DDD, Aroclor 1254, and Aroclor 1260 were found at concentrations below 0.4 ppm for 13 of 14 samples. The low correlations among DDT and its metabolites in CAMs suggest herons are not being exposed to a consistent source of these compounds. Comparison of chlorinated hydrocarbon data for CAMs from three Puget Sound heron colonies, NAS Whidbey, Samish Island and Dumas Bay, indicates contaminant burdens in herons from NAS Whidbey and Samish Island are significantly lower than burdens in herons from Dumas Bay.

The simulations model space/time-developing compressible (subsonic) jets, using species-and temperature-dependent diffusive transport, and finite-rate chemistry appropriate for H-2 combustion. Comparative measurements of entrainment for square jets are obtained based on evaluations of streamwise mass-flux to obtain an assessment on how the jet development is affected by chemical exothermicity and density differences between the jet and the surroundings. Depending on initial conditions (i.e., on the chemical exothermicity level implied by the initial reactant concentration), chemical energy release and expansion effects can be significant in determining reduced entrainment and initial jet growth relative to corresponding nonreactive jets. The instantaneous product formation rates are closely correlated with the local entrainment rates controlled by the vorticity bearing fluid. Instantaneous entrainment rates-based on the rate of increase of mass flux of rotational fluid-are found to be significant in the regions of roll-up and initial self-deformation of vortex rings, and then farther downstream, in the vortex merging region, where fluid and momentum transport between the jet and its surroundings are considerably enhanced by the presence of hairpin vortices aligned with the corners, Analysis of the combustion dynamics in terms of scalar mixing fraction diagnostics previously used in laboratory reactive turbulent jet experiments, was shown to be also potentially useful in characterizing their transitional regime by bringing out the relation between product formation rates and underlying fluid dynamical events.

Fracture toughness (K-c) measurements were made on all composites using the applied moment double cantilever beam technique. The measured toughness values for the layered composites were found to be equivalent to those of the single-volume-fraction composites. The fracture toughness measured for the layered composites was found to be dependent on the volume of composite phase tested and ultimately on the number of crack-particle interactions which occurred. R-curve like behaviour was observed in the layered composites. RP JESSEN, TL (reprint author), USN,RES LAB,CERAM & COMPOSITES BRANCH,CODE 6373,WASHINGTON,DC 20375, USA.

Results are presented for varying the AlN buffer layer thickness. The electron Hall mobilities of the GaN films grown on a-plane were, in general, higher than that of the corresponding growth on c-plane sapphire. Because electron mobilities obtained on a-plane sapphire are large (> 300 cm(2)V(-1)s(-1)) over a wide range of buffer layer thicknesses (115 Angstrom to 375 Angstrom), growth on a-plane may be more desirable for mass production of GaN-based devices.

The effect of compensation on the 300 K mobility is also calculated and compared to the best n-type transport data reported by several groups for both unintentionally doped and intentionally doped samples. These data probably represent transport properties intrinsic to wurtzite GaN on sapphire. In addition, variable-temperature electron transport results from unintentionally doped samples are discussed and compared to previous investigations. In the latter case, the data probably indicate that an important compensation mechanism is due to the parallel transport of charge by impurity conduction.

Isothermal and non-isothermal calorimetric measurements are analyzed and compared between samples where H2O was replaced either by 1N HCl, 1N NaOH or .5 NaCl. The ice nucleus density is calculated from direct cryomicroscopic observations. The Johnson-Avrami-Mehl (JMA) model is used to characterizing the isothermal crystallization. Amounts of ice are recorded during cooling for comparison. The substitution of H2O by a salt solution decreases the nucleation rate and obviously lowers its thermal range. Activation energies for ice crystal growth at constant molal salt concentrations are similar. The ratio K-o/N-1/n where N is the nucleus density, K-o is the kinetic constant and n the Avrami exponent for the crystallization is also presented as representative of the crystal growth. At constant molality, basic solutions present the lowest nucleation rate and crystal growth. For cryopreservation by vitrification, the present results support the notion for a better vitrification tendency and lower crystal growth for solution having an excess of OH-. The choice still remains for a less toxic physiological solution. C1 USN,MED RES INST,TRANSFUS MED RES PROGRAM,BETHESDA,MD 20889.

The eddies move southwestward along the southeast edge of the East Greenland Current. The path of the eddies is coincident with the location of numerous deep current meter observations from previous surveys during which the strong pulses of overflow water (recorded speeds of over 150 cm s(-1)) had spectra peaked at periods of 1.5-2.5 days. It is suggested that the pulses are the signal observed from energetic, propagating cyclonic vortices extending up to the surface layer and formed by vortex stretching associated with the sinking of dense overflow water downstream from the sill of the Denmark Strait and along the shelf slope. The signature of the vortices at the sea surface appears in the IR imagery as a cold cyclonic eddy often exhibiting a pronounced spiral configuration. Because the entire water column in the slope region would be subjected to strong mixing by the vortices, considerable modification of not only the cold overflow water but also the intermediate and surface layers would occur.

It is found that the method of moments (MM) and the physical optics approximation (PO) are in close agreement in the radiation case, even for reflector diameters as small as 1 lambda. This assumed that the reflector is in the far-field of an ideal feed (no blockage). Additional gain calculations using the feed near-field terms were not substantially different than the physical optics result, at least for feed diameters as large as the reflector radius. For plane wave scattering the agreement is not as good, but the physical optics result is still within a few dB of the method of moments. Neither the MM or PO data revealed significant resonances for these small reflectors when they were illuminated by ideal focal point feeds.

To adequately identify such fuels, factors that realistically impact on thermal stability were examined. Evaluation was based on a quantitative method of measuring thermal stability, viz., NRL's recently developed gravimetric JFTOT. This method gives a quantitative measurement of both the strip deposit and filterables formed. The pertinent factors examined included the individual and interactive effects of soluble copper, MDA (metal deactivator), and aging. Aging was accelerated to simulate field conditions of approximately 6 months storage at ambient temperature and pressure. The results indicate that the individual and interactive effects of copper, MDA, and accelerated aging appear to be fuel dependent. On the basis of the results, the three test fuels examined (one JP-8 and two JP-5s) were categorized as exhibiting very good, typical, and poor thermal stabilities, respectively. for both the very good and poor thermal stability fuels, copper in conjunction with aging did not significantly increase the total thermal deposits of the neat fuels. In contrast, for the typical thermal stability fuel, the combined effect of copper and accelerated aging did increase deposits. Furthermore, the addition of MDA prior to aging of the copper-doped, typical stability fuel significantly counteracted the adverse effect of copper and aging. No such beneficial effect of MDA was observed for the poor stability fuel. These findings focus attention on the compositional differences among fuels and the need to elucidate these differences (physical and chemical) for a better understanding and prediction of the fuels' performances.

This paper addresses the successful development of such a method. The proposed test method entails measuring the hydroperoxide concentration formed after stressing at 100 degrees C and 345 kPa air overpressure for 24 h with the option to extend to 48 h should this be necessary. Application of the proposed test method to worldwide current production fuels attests to the sensitivity of the method in differentiating fuels with differing storage stabilities.

Improved information may not only help insure that wells are economic, but may also lead to reduced costs of production and an increased physically recoverable stock of the resource. This paper empirically applies the economic theory of exhaustible resources (extended to include necessary reservoir engineering) to evaluate the benefits obtainable from using an enhanced information technology developed by the Gas Research Institute. The wells analyzed indicate significant benefits are obtainable with appropriate use of the new technology. The magnitudes of these benefits vary across reservoir characteristics.

Two specimens were considered in the experimental portion of the study, differing with respect to thickness and the presence of side grooves. Plane stress and plane strain finite element analyses of the specimens were conducted to assess the relative role of constraint on load vs crack opening displacement response and crack growth initiation. A critical value of the strain energy density associated with local material fracture was used to predict the onset of crack growth. The experimental responses were bounded by the predicted plane stress and plane strain load vs crack mouth opening responses. These results also provided an indication of the extent to which the side grooves in the thinner specimen provided more constraint than the thickness of the specimen without side grooves. A comparison with a previous investigation on an HY-100 compact fracture specimen suggests similarities concerning the interaction between material nonlinearity and specimen response nonlinearity.
