The wedge is formed by taking a thin ground plane and applying a bend to create a sharp edge which is parallel to the columns of slots in the infinite axis. Results are derived for thin linear slots whose major axes are either parallel or perpendicular to the edge. A hybrid moment method and geometrical theory of diffraction approach is used, with magnetic current expansion functions defined using Floquet's theorem on single columns of slots. Predictions generally agree with scattering measurements of finite by finite array physical models with monostatic patterns taken in a plane orthogonal to the sharp edge.

During elevated intracranial pressure and intact regulation, positive pressure inhalation appears to briefly occlude venous Bow into the cranial sinuses during inspiration. As a result, the intracranial pressure and arterial pressure signals are not similar, In contrast, when maximal dilation causes failure of regulation of cerebral blood flow, the intracranial pressure signal is approximately proportional to the arterial pressure signal. Comparison of the crosscorrelation function derived from the intracranial and arterial pressure signals to the autocorrelation function of the arterial signal reveals that the two correlation functions are: 1) different during intact regulation and 2) nearly identical during dilation induced failure of regulation of cerebral blood flow.

A comparison of ($) over bar sigma(theta, phi, L) with experimental data show good agreement, lending strong credibility to the hypothesis that E-randomness is responsible for the shape of the upset cross section curve, The expected value model is used as the basis for a new, rigorous mathematical formulation of the effective cross section concept, The generalized formulation unifies previous corrections to the inverse cosine scaling, collapsing to Petersen's correction, [cos theta - (h/l) sin theta](-1), near threshold and Sexton's, [cos theta + (h/l) sin theta](-1), near saturation, The expected value cross section model therefore has useful applications in both upset rate prediction and test data analysis.

The paper reviews the studies dealing with environmental and viscoelastic effects on stresses in adhesive joints. Environmental factors that affect stresses include temperature and moisture. These factors are analyzed, and practical examples that illustrate their impact on adhesives are given for the solid-rocket motor, which is a structural component paramount to the U.S. space program. The paper deals with viscoelastic effects on adhesive joints, and a number of viscoelastic models used in the analysis of viscoelastic materials, including adhesives, are reviewed. The use of the solid-rocket motor as an example characterizes the circumstances where viscoelastic properties of adhesive layers are essential. Close attention is paid to the fractional derivative model of Bagley and Torvik, which may be a good candidate for an analytical study of adhesive joints. Finally, existing studies on viscoelastic adhesive joints are considered. C1 UNIV MISSOURI,CTR ENGN EDUCAT,DEPT MECH ENGN,ST LOUIS,MO 63121.

The purpose of this study was to determine the sting attack rate and development of specific IgE in an unsensitized population. Methods: Study participants consisted of 137 medical students with limited exposure to IFA-endemic areas who were temporarily training in San Antonio, Tex. Subjects were surveyed for prior IFA exposure with a questionnaire, and IFA-specific IgE was evaluated with RAST and intradermal skin testing. Evaluations were performed on arrival and reported at departure from the endemic area 3 weeks later. Results: One hundred seven subjects completed the study. Field stings were reported in 55 subjects, resulting in a sting attack rate of 51%. In these 55 subjects 53 (96%) reported a pustule or a small local reaction at the sting site, one (2%) reported an isolated large local reaction, and none reported a systemic reaction. At the 3-week follow-up skin test and RAST conversions occurred in seven subjects (13%) and in one subject (1.8%), respectively. Conclusions: Even brief exposures to IFA-endemic areas result in significant sting rates and concurrent rapid development of IFA-specific IgE in 16% of stung subjects.

Participants were 332 military recruits (227 men, 105 women), 86 of whom were smokers who quit during 6 weeks of basic training. Results showed no significant weight changes for smokers who quit. Pretest smoking rates and feat of weight gain were unrelated to changes in weight. Results suggest that an intensive program that limits access to alcohol and foods that are high in fat and that increases physical activity can attenuate weight gain after smoking cessation.

However, the role of PAF in oral pathobiology remains unknown. The purpose of the present study was to evaluate the relationship between salivary PAF levels and the severity of periodontal inflammation. PAF activity in lipid extracts of whole (mixed) saliva collected from 69 untreated subjects immediately prior to routine oral evaluation was determined by platelet bioassay. Significant positive correlations were observed between the level of PAF in saliva and measures of periodontal inflammation, i.e., the percentage of periodontal probing depths greater than 4 mm, the number of periodontal bleeding sites, and the number of histologically identified polymorphonuclear neutrophilic leukocytes (PMN) in saliva. Moreover, when subjects were subdivided into groups on the basis of periodontal probing depths, a significant correlation was observed between salivary PAF levels and the extent of periodontal disease, i.e., PAF levels in saliva progressively increased from the healthiest group to the most severely affected group. Thus, salivary PAF levels correlate with the severity of periodontal inflammation. These results support the hypothesis that this pro-inflammatory phospholipid autacoid may participate in the pathogenesis of periodontal tissue injury and disease.

Thermal loads were imparted to the bearing by the hands of a bearing technician during a rework operation. A worst-case analysis was examined by assuming a three-minute dwell time and diametrically symmetric thermal loading. Contact temperature was experimentally determined and used in conjunction with a numerical model to simulate thermal propagation throughout the bearing outer ring. Diametric deflection data, obtained using the contact temperature in conjunction with analytic and finite elements, have been shown fr comparative purposes. Experimental diametric expansions of the bearing outer ring were determined and compared with the predicted results. Assuming a worst-case scenario, this investigation yielded vertical expansions in the bearing outer ring's diameter, which would be problematic for some bearings during the rework operation; appropriate corrective action was discussed.

We constructed three TCDD exposure indices from the questionnaire data: the number of days of skin exposure (DAYS), the percentage of skin area exposed (PCNT), and a combined index (SRI) which was the product of these and the concentration of TCDD in the herbicide. A fourth index (AFI) based on gallons of herbicide sprayed and the number of men on the job was also studied. The regression model most predictive of TCDD levels (R(2) = 0.61) included job classification (divided into four categories), the number of days of skin exposure, percent body fat during the tour of duty, and relative change in body fat. A model with job classification alone had an R(2) of 0.60. The four exposure indices were constructed to further explain TCDD exposure in the job classifications with the highest potential for exposure: Ranch Hand flight engineers and ground crew.

Various theories have been developed to predict compressive strength of rigid-rod fibres. In this study the critical buckling stress for rigid-rod fibres with stiff external coatings has been theoretically modelled assuming that the failure mode in compression is the microbuckling of the fibrils in shear. Our model predicts that significant improvement in fibre compressive strength will occur only when relatively thick coatings, with thickness to diameter (t/D) ratios in excess of > 0.05, are used. Experimentally measured compressive strength of aluminium coated PBZT fibres shows values in good agreement to the theory at t/D ratios of 0.006 and below. Factors related to the selection of suitable coating materials and problems associated with establishing coating performance are identified. C1 ADTECH SYST RES INC,DAYTON,OH 45432.

Both methods use the locations of the maximal reconstructed count values determined from a perfusion quantification procedure as a basis for generating surfaces. Methods: The first method fits circular contours, which are perpendicular to the long-axis, to the points obtained from perfusion quantification. The second method applies median and linear filters to the points to remove noise but maintain the basic shape of the surface. Both models are validated against an automatic technique and against the user-traced surfaces of both the perfusion image and an MR image of the same patient. Results: The median-filtered model was found to be closer to the standard surfaces than the circular model in all cases, and 85% of the points on the median-filtered surfaces were within one SPECT pixel length of the hand-traced MR surfaces. Conclusion: Accurate, three-dimensional left ventricular epicardial surfaces can be generated quickly and easily from already existing perfusion quantification software.

Also, the toxicological response of these cells to cocaine was compared to previously published results obtained with perfused liver cells and in vivo systems. Our experiments indicated that Hep-G2 appear to have similar metabolic and toxicological patterns to in vivo and perfused cell systems. The WRL-68 tissue culture system was found to be less similar. These results suggest Hep-G2 cells can be utilized to study cocaine metabolism and toxicology, and possibly in studies involving other xenobiotic compounds.

CONCLUSIONS: Patients in the SICU who survived CPR had a stable or improving clinical course as determined by APS and GCS score and had not had acute organ failure. Patients who were critically ill with a declining clinical course did not survive after CPR. C1 UNIV N CAROLINA,SCH MED,DEPT SURG,CHAPEL HILL,NC.

In this paper we present a new analysis of this resonance condition by two methods: first by studying the dynamics on the unperturbed (epsilon = 0) momentum sphere, and second by studying the slow evolution of rotational kinetic energy when epsilon not equal 0. Since resonance capture is related to a separatrix crossing and is an uncertain event, we discuss the probability of capture, and its relationship to the magnitude of the spinup torque epsilon.

For the straight geometry, critical heat flux (CHF) did not vary much for heights greater than 1.14 mm, The percent increase in curved channel CHP over straight channel CHF was highest for 5 degrees C subcooling, This implies that buoyancy effects are most important when there is significant vapor generation, For a given subcooling and velocity, the radius of curvature had little effect, This implies that secondary flow has little effect under these conditions, A correlation is developed that describes the effects of buoyancy and secondary flow on CHF in the curved channel.

Another important objective is the determination of the surface heat flux from measured temperatures within the body. This article is unique because the thermal properties are being estimated with known heat flux and temperature histories; then the opposite problem of recovering the heat flux history is solved using the estimated values for the thermal properties and temperature history. This calculated heat flux history can then be compared with the measured input heat nux. Results were obtained for a temperature range of 30-600 degrees C. The thermal properties demonstrate a presumed quadratic relationship with temperature, and a good agreement between the estimated and measured heat flux histories is demonstrated.

The underlying assumption is that dislocation slip and annihilation are probabilistic events. The resulting mathematical framework takes the form of renewal theory from probability theory. Renewal creep theory provides a mathematical framework for primary creep that accommodates previously developed empirical descriptions. Renewal creep theory also predicts the existence of secondary creep as an asymptotically constant strain-rate phenomenon. Creep modeling techniques are demonstrated for three titanium alloys.

In this paper, a three level ESS model is presented for a complex electronic system. Screening is performed at the component, board and system level. Components are screened for a specified duration before being assembled into printed circuit boards (PCBs). Defects introduced during the assembly of the PCBs are screened at the board level, while defects introduced during final assembly are screened at the system level. Components and connections are assumed to come from good and substandard populations and their times-to-failure distributions are modeled by mixed distributions. Mixed exponential distributions are used to model component times-to-failure and mixed Weibull distributions are used to model the times-to failure for board and system level connections. The mixed Weibull distributions are used to model wearout characteristics at the board and system level. Optimal screen durations in the presence of wear-out are obtained by minimizing the systems life-cycle cost. ESS is shown to be a cost effective strategy when properly implemented. The optimal screening strategies are shown to be relatively robust to the system warranty period. C1 UNIV ARIZONA,TUCSON,AZ 85721.

Data from the national ECMO registry were collected on all patients who received ECMO over a 2-year period in established centers. Stepwise multivariate analysis was used to determine the relative contribution of different factors in the development of ICH. Data on 972 infants were evaluated; the overall incidence of ICH was 11%. There was a progressive increase in incidence with prematurity, acidosis, and hypercarbia. The best positive predictive value was 60% using all available factors. The premature as well as the term infant with severe metabolic acidosis and hypercarbia has the highest risk to develop ICH on ECMO. Conditions present prior to institution of ECMO therapy have a significant impact on outcome. Although the best predictive ability is only 60%, patients at greatest risk to develop ICH can be identified. Prompt referral and institution of bypass in these patients, when indicated, may modify the subsequent course. C1 WILFORD HALL USAF MED CTR,DEPT PEDIAT,LACKLAND AFB,TX 78236.

A discrete-continuous task pair was purposely chosen to allow fine-grained analysis of time-shared performance. The relative priority of the dual task was manipulated by a secondary task technique to test for performance tradeoff that would be indicative of resource allocation. The temporal predictability of the discrete stimuli was manipulated to examine possible strategic avoidance of interference. The moment-by-moment data did not reveal any evidence for a switching strategy. It was concluded that the intricate interference patterns could be more easily interpreted within the resource framework than within the outcome-conflict framework.

Practically, lateral resolution on the order of 50 Angstrom at 1.0 keV accelerating voltage can be obtained in polymer samples. The utility of LVHRSEM is demonstrated for diverse polymer systems, both amorphous and crystalline, with structurally interesting features on a 50-1000 Angstrom length scale. The advantages and disadvantages of LVHRSEM as a polymer characterization technique are investigated, as well as the effects of beam-sample interactions, radiation damage and contamination specific to polymers examined at low voltage.

It is derived from the theory that the recombination current at the extrinsic base surface increases with time due to the surface degradation process. Furthermore, the initial 1/f noise and base leakage current characteristics have been used to provide the needed model parameters for the HBT surface recombination mechanism and surface quality, respectively. The current gain long-term variations calculated from the model for four HBTs compare favorably with those obtained from measurements. The model proposed is potentially useful to screen unreliable HBT lots without having to carry out the long-term stress test.

Here we report that this phenomenon can be significantly modulated by the type of anesthesia administered to the pregnant dam before the conditioning procedure. Dams were anesthetized with one of the following drugs or drug combinations: (1) sodium pentobarbital; (2) ketamine hydrochloride and xylazine; or (3) sodium pentobarbital and ketamine hydrochloride. While under the influence of these anesthetics, rat fetuses received pairings of Sac + LiCl or one of the following sets of oral and systemic (i.p.) control injections: Sac + Saline, H2O + LiCl; H2O + Saline. At age 15 days neonatal rats were given a taste preference test by allowing them to select nipples painted with either saccharin or vehicle (H2O). After weaning, rats were given an additional taste preference test where they were allowed to drink from bottles filled with either 0.30% saccharin or water. Neonates that received Sac + LiCl injections avoided saccharin-painted nipples while neonates that received control injections in utero preferred saccharin-painted nipples. Rats that acquired the taste aversion under the influence of ketamine showed a significantly stronger conditioned taste aversion on the nipple preference test than did those from dams injected with sodium pentobarbital. The conditioned taste aversion was not detectable later during the bottle preference test. Since ketamine blocks N-methyl-D-aspartate (NMDA) glutamate receptors, and these receptors have been implicated in neural plasticity during development, our data suggest that NMDA antagonism can potentiate fetal learning. Ketamine has been used as an obstetrical and pediatric anesthetic. Thus, the data presented here may have clinical implications as well.

THEORY SO OPTICS COMMUNICATIONS LA English DT Article AB We develop a variational, scalar-field treatment of the guided modes and their propagation constants for a multiple-core optical fiber consisting of many single-mode single fiber cores closely spaced inside a common cladding material. The variational procedure, when supplemented with symmetry considerations, produces without great effort the modes and their wavevectors for a highly symmetrical arrangement of an arbitrary number of cores. By employing these modes, we compute an expression for the coupling efficiency of an arbitrary wavefront focused into such a fiber. We argue that such a fiber should be more strongly coupled than the standard single-core single-mode fiber to an arbitrary wavefront due to a piecewise coupling of the wavefront to the multiple-core fiber. The improved coupling efficiency is illustrated with the example of a focused plane wave, for which a periodic spatial redistribution of energy among the cores, as a function of the propagation distance, is also verified. In the following paper, we demonstrate dramatic improvements in coupling efficiency for an atmospherically aberrated wavefront focused into a multiple-core fiber, a result with considerable implications for ground-based fiber-coupled interferometry.

APPLICATION TO GROUND-BASED INTERFEROMETRY SO OPTICS COMMUNICATIONS LA English DT Article ID OPTICS AB In the preceding paper, we developed a variational approach to address the coupling of an optical field and the propagation of the coupled field in a multiple-core optical fiber consisting of many single-mode single fiber cores closely spaced inside a common cladding material. Here, we apply the results of that paper to discuss quantitatively the matter of coupling into a multiple-core fiber wavefronts that have been aberrated by propagation through a turbulent atmosphere, a situation characteristic of ground-based imaging systems. Specifically, we compare the coupling efficiencies for a multiple-core fiber with those for a standard single-core single-mode fiber, and show that the multiple-core fiber can out-perform the standard fiber many-fold. We also consider the propagational evolution of the relative core excitation and coherences in the guided light. Under changing conditions of atmospheric turbulence, the optimal design parameters of the MC fiber are remarkably robust, a fact that makes MC-fiber couplers very attractive for ground-based interferometry.

The correctable field of view is of the order of 5-10 mu rad at visible wavelengths and increases as the wavelength increases. Previous concepts to broaden the corrected field of view have been hardware oriented, requiring multiple wave-front sensor (WFS) measurements to control multiple deformable mirrors. We analyze the average and the signal-to-noise-ratio performance of an image measurement and postprocessing technique that uses simultaneous measurements of a short-exposure compensated image measured in an off-axis direction; an additional WFS measurement is taken in the off-axis direction. Results are presented for infinite-altitude WFS beacons driving both the WFS for the adaptive optics and the WFS looking in the off-axis direction, a variety of seeing and WFS light-level conditions, and off-axis angles from two to six times the isoplanatic angle. This technique improves the average effective transfer function out to a field angle of at least six times the isoplanatic angle which providing a higher signal-to-noise ratio in the spatial frequency domain.

National Institute for Occupational Safety and Health (NIOSH) Method 5521 uses an impinger filled with 1-(2methoxyphenyl)piperazine in toluene for collection and derivatization, HPLC separation, and simultaneous UV and EC detection. This method was compared directly to Occupational Safety and Health Administration (OSHA) Method 42, which is based on sample collection on a fiber filter coated with 1-(2-pyridyl)piperazine, HPLC separation, then UV detection. NIOSH Method 5521, modified so that polyisocyanate concentrations were determined based on polyisocyanate standards, also was compared with NIOSH Method 0500, which is a gravimetric assay for total particulates. The results for HDI monomer demonstrate that NIOSH Method 5521 appears to give higher results than those obtained using OSHA Method 42, especially when the total particulate concentration is high. Furthermore, field studies show that polyisocyanate concentrations during spray paint operations may exceed a concentration of 1 mg/m(3), which is believed to be hazardous. Finally, preliminary results indicate that the true concentration of polyisocyanate in air, in all cases but one, was within two rimes the theoretical concentration based on the total particulate mass.

The skeletons represented 50 males and 50 females distributed equally by race, i.e., whites and blacks. Linear-regression equations, with standard errors ranging from 4.09 to 6.11 cm, were derived from these measurements for the purpose of estimating stature. Two independent control samples, including one comprised of remains of American servicemen lost in World War II and the Korea and Vietnam wars, were tested with relatively accurate results.

Survey questions included numbers and types of cases for which TEE is used, who interprets TEE data and how they are trained, the extent of resident training in TEE, and beliefs about the utility of TEE. One hundred eight completed surveys were returned (70% response). Of those responding, 98 (91%) use intraoperative TEE. In 53 of those 98 institutions (54%), an anesthesiologist was primarily responsible for the interpretation of TEE data, whereas a cardiologist was responsible in the remainder. Approximately 35% of anesthesiologists using TEE had training in its use during residency or fellowship; the remainder were trained after finishing residency or fellowship. Forty-two percent of anesthesiologists who use TEE leave a formal interpretation on the chart apart from the anesthesia record, and 43% bill specifically for performing TEE. Although 69% of those responding thought that formal credentials should be required for anesthesiologists to use intraoperative TEE, only 32% reported that their institutions actually mandated this. 38% of those responding stated that they offer a dedicated TEE rotation to their residents, and 13% thought that their graduating residents were trained well enough to use TEE on their own. Among academic institutions responding, the use of intraoperative TEE is nearly universal, responsibility for its interpretation is split almost evenly between cardiologists and anesthesiologists, and there is a disparity between opinions and reality with regard to TEE credentialing for anesthesiologists.

The most frequent indications for amphetamine use were ''aircrew fatigue'' and ''mission type,'' Of pilots who used amphetamines, 58-61% considered their use beneficial or essential to operations, Dextroamphetamine (5 mg every 4 h) was used effectively and without major side effects in tactical flying operations, Amphetamine use enhanced cockpit performance and flight safety by reducing the effect of fatigue during critical stages of flight.

Unlike ground-based shakers, reaction-mass devices have a position constraint which must be maintained. A two-part system identification procedure is described which maintains this constraint. In the first part, a new algorithm is used to obtain the impulse response from input-output data. The second part uses the eigensystem realization algorithm to determine linear matrix models of the structure and of the reaction-mass device. This procedure is demonstrated on a small experimental structure. The usefulness of the model for the design of a vibration suppression controller is also demonstrated.

Axial sections throughout the length of the animals were collected. Sections were 3 mm thick for the rat and 5 mm thick for the monkey and goat. Sagittal sections (2 mm thick) of the rat head were also scanned. Images were recorded on magnetic tape and transferred to computer disk for image enhancement and network distribution. Images are available in 16 bit Big Endian signed or 8 bit TIFF formats. This is the first database of contiguous MRI axial scans of rat, monkey, and goat available for distribution via magnetic tape (4 mm DDS) or Internet file transfer protocol. Digital transfer of the data was selected to preserve the integrity of each image, circumventing the need for the user to scan the images back into a digital format for use with their software. These images should be useful to physiologists, neuroscientists, veterinarians, anatomists, and teachers. Reconstructing these 2-dimensional images into 3-dimensional structures is an effective media for conveying spatial anatomical information in a quick and comprehensive manner.

These cost effective environments facilitate access to technologies such as VXI, provide speedy development of highly effective user interfaces, and eliminate many of the tasks often associated with hardware integration in complex test systems. Nonetheless, difficulties can arise when designing functional and diagnostic test software in this environment. This paper introduces VISTA, a promising new architecture which allows users to elude most of the difficulties of building detailed functional and diagnostic Test Program Sets (TPSs), while taking full advantage of the benefits of diagrammatic programming environments. Here we examine an implementation of the VISTA architecture, the integration of advanced diagnostics, and the use of diagrammatic programming as a test language cross compiler.

The proposed device consists of three nonlinear crystals in series inside a cavity resonating tight at a signal frequency omega(s). Sum-frequency generation (SFG) in the first crystal produces the desired radiation, omega(s) + omega(p) = omega(d). Second-harmonic generation (SHG) in the second crystal doubles the frequency of the residual pump, 2 omega(p) = omega(h), while the signal passes through unaffected, Optical parametric oscillation (OPO) in the third crystal generates the signal and idler frequencies, omega(h) = omega(s) + omega(i). A plane-wave analysis predicts a quantum efficiency close to 30% over an extended range of pump intensity. Iteration of the plane-wave solutions over many passes yields dynamics very similar to that recently calculated for the SFG-OPO device, As in that device, a small detuning of the SFG interaction enlarges the dynamic range yielding stable operation. Highest efficiency occurs when omega(i) is at the low-frequency end of the OPO crystal transmission window, As an example, we consider a device using a noncritically phase-matched KTP SFG crystal, a quartz crystal polarization rotator, an angle-tuned KTP SHG crystal, and a noncritically phase-matched LiNbO3 OPO crystal. This device is designed to convert lambda(p) = 1.064 mu m to lambda(d) = 0.455 mu m. We calculate a power conversion efficiency as great as 73%.

Eight healthy volunteers underwent HDBR for 2 wk. Antecubital venous blood was sampled for plasma levels of catechols [norepinephrine (NE), epinephrine, dopamine, dihydroxyphenylalanine, dihydroxyphenylglycol, and dihydroxyphenylacetic acid] after supine rest on a control (C) day and after 4 h and 7 and 14 days of HDBR. Urine was collected after 2 h of supine rest during day C, 2 h before HDBR, and during the intervals 1-4, 4-24, 144-168 (day 7), and 312-336 h (day 14) of HDBR. All subjects had decreased plasma and blood volumes (mean 16%), atriopeptin levels (31%), and peripheral venous pressure (26%) after HDBR. NE excretion on day 14 of HDBR was decreased by 35% from that on day C, without further trends as HDBR continued, whereas plasma levels were only variably and nonsignificantly decreased. Excretion rates of dihydroxyphenylglycol and dihydroxyphenylalanine decreased slightly during HDBR; excretion rates of epinephrine, dopamine, and dihydroxyphenylacetic acid and plasma levels of catechols were unchanged. The results suggest that HDBR produces sustained inhibition of sympathoneural release, turnover, and synthesis of NE without affecting adrenomedullary secretion or renal dopamine production. Concurrent hypovolemia probably interferes with detection of sympathoinhibition by plasma levels of NE and other catechols in this setting. Sympathoinhibition, despite decreased blood volume, may help to explain orthostatic intolerance in astronauts returning from spaceflights. C1 NASA,AMES RES CTR,MOFFETT FIELD,CA 94035.

An intraperitoneal (i.p.) injection of 150 mg/kg TRYPT significantly stimulated serotonin (5-HT) release in the suprachiasmatic nuclear (SCN) region, as reflected by a 205 +/- 30% maximal increase in the extracellular concentration of 5-HT assessed using microdialysis. Administration of TRYPT 1 h before exposure to a light pulse (30 min, 40 lux) delivered during late subjective night dose-dependently suppressed the number of SCN cells expressing light-induced Fos-like immunoreactivity (Fos-LI; maximal suppression @200 mg/kg was 77 +/- 4%, p < 0.001). This action of TRYPT was attenuated by pretreatment with the 5-HT1a antagonist, NAN-190, and was abolished by the 5-HT2/5-HT7 antagonist, ritanserin, or the nonselective 5-HT antagonist, metergoline (all 10 mg/kg). These antagonists alone had no effect on light-induced Fos. In a second experiment, pretreatment of free-running hamsters housed under constant darkness with 150 mg/kg TRYPT 45-60 min prior to light exposure (10 min, 20 lux) during late subjective night (CT 19) significantly attenuated the Light-induced phase advances of the circadian activity rhythm (66 +/- 7 min vs. 100 +/- 6 min for vehicle controls; p < 0.001). The same dose of TRYPT given 1 h before Lights-on for 5 consecutive days in hamsters maintained under 14L:10D altered the phase angle of entrainment such that activity onsets were delayed by 36 +/- 8 min relative to controls (p < 0.05). The same dose of TRYPT administered during late subjective night also suppressed the extracellular concentration of glutamate in the SCN region assessed using microdialysis (55 +/- 8% suppression; p < 0.05 vs. baseline). These results support the hypothesis that the ascending serotonergic projection to the SCN modulates photic entrainment processes within the circadian oscillator.

Human osteoblast-like cells (MG63) were cultured on titanium (Ti) disks that had been prepared by one of five different treatment regimens. All disks were pretreated with hydrofluoric acid-nitric acid and washed (PT). PT disks were also: washed, and then electropolished (EP); fine sandblasted, etched with HCl and H2SO4, and washed (FA); coarse sandblasted, etched with HCl and H2SO4, and washed (CA); or Ti plasma-sprayed (TPS). Standard tissue culture plastic was used as a control. Surface topography and profile were evaluated by brightfield and darkfield microscopy, cold field emission scanning electron microscopy, and laser confocal microscopy, while chemical composition was mapped using energy dispersion X-ray analysis and elemental distribution determined using Auger electron spectroscopy. The effect of surface roughness on the cells was evaluated by measuring cell number, [H-3]thymidine incorporation into DNA, alkaline phosphatase specific activity, [H-3]uridine incorporation into RNA, [H-3]proline incorporation into collagenase digestible protein (CDP) and noncollagenase-digestible protein (NCP), and [S-35]sulfate incorporation into proteoglycan. Based on surface analysis, the five different Ti surfaces were ranked in order of smoothest to roughest: EP, PT, FA, CA, and TPS. A TiO2 layer was found on all surfaces that ranged in thickness from 100 Angstrom in the smoothest group to 300 Angstrom in the roughest. When compared to confluent cultures of cells on plastic, the number of cells was reduced on the TPS surfaces and increased on the EP surfaces, while the number of cells on the other surfaces was equivalent to plastic. [H-3]Thymidine incorporation was inversely related to surface roughness. Alkaline phosphatase specific activity in isolated cells was found to decrease with increasing surface roughness, except for those cells cultured on CA. In contrast, enzyme activity in the cell layer was only decreased in cultures grown on FA- and TPS-treated surfaces. A direct correlation between surface roughness and RNA and CDP production was found. Surface roughness had no apparent effect on NCP production. Proteoglycan synthesis by the cells was inhibited on all the surfaces studied, with the largest inhibition observed in the CA and EP groups. These results demonstrate that surface roughness alters osteoblast proliferation, differentiation, and matrix production in vitro. The results also suggest that implant surface roughness may play a role in determining phenotypic expression of cells in vivo. (C) 1995 John Wiley & Sons, Inc.

Accumulation of direct microbiologic evidence of the relationship between the organism and the syndromes compatible with cat scratch disease has been hindered by the difficulties in the primary isolation of the organism from infected tissue specimens. A chemically defined liquid medium was developed to support the growth of Rochalimaea species to facilitate study of the organism. This medium was also used successfully to isolate R. henselae from clinical specimens from infected patients and a domestic cat. Recovery of R. henselae in this was more successful than when recovery was attempted on solid agar. This cell-free, extract-free, defined medium additionally supported the growth of Rochalimaea quintana and Afipia felis.

Sixty mesial canals of extracted human mandibular molars were randomly divided into five groups. The roots were embedded in clear resin and cross-sectioned in the apical and mid-root areas, In group A, canals were instrumented using a quarter turn/pull technique with K-Flex files. In group B, canals were prepared with Ni-Ti hand files (Mity files) using the same technique as in group A. Group C was prepared with NT Sensor engine-driven files. Group D canals were prepared with Ni-Ti Canal Master ''U'' hand instruments. Group E was prepared with engine-driven Ni-Ti Lightspeed instruments. Digitized images of the uninstrumented canals were compared with images of the instrumented canals. Engine-driven Ni-Ti instruments (Lightspeed and NT Sensor file) and hand instrumentation with the Canal Master ''U'' caused significantly less canal transportation (p < 0.05), remained more centered in the canal (p < 0.05), removed less dentin (p < 0.05), and produced rounder canal preparations than K-Flex and Mity files. Engine instrumentation with Lightspeed and NT Sensor file was significantly faster than hand instrumentation (p < 0.05). C1 WILFORD HALL USAF MED CTR,DEPT ENDODONT,LACKLAND AFB,TX 78236.

Previous research used a comparison microscope to match fibers and fiber impressions between a correction ribbon and a document. However, because of inherent features of the correction ribbon system, several difficulties were encountered. Consequently, a scanning electron microscope (SEM) was used to alleviate some of the problems discovered by past research. The SEM, with its greater magnification power, detected both fibers and fiber impressions, creating a basis for association between a questioned document and a correction ribbon. Use of SEM also ameliorated the problems of past research and greatly enhanced points of comparison. C1 GEORGE WASHINGTON UNIV,DEPT FORENS SCI,WASHINGTON,DC. ARMED FORCES INST PATHOL,WASHINGTON,DC.

When 1-(dimethylsulfamoyl)-2-(tert-butyldimethylsilyl)imidazole was lithiated by sec-hutyllithium, followed by methyl formate, there was obtained 1-(dimethylsulfamoyl)-2-(tert-butyldimethylsilyl)-5-imidazolecarboxaldehyde (57%). Removal of the silyl group by acetic acid yielded 1-(dimethylsulfamoyl)-5-imidazolecarboxaldehyde (11, 96%) as a gum. Isomerization of 11 took place slowly at room temperature (10 days), or faster in tetrahydrofuran solution containing triethylamine (2 hours) to form crystalline 1-(dimethylsulfamoyl)-4-imidazolecarboxaldehyde (12) in 68% yield. Proton and carbon-13 nmr spectra were analyzed to determine the structure of the isomers. However, only X-ray,crystallography established the structure of 1-(dimethylsulfamoyl)-4-imidazolecarboxaldehyde unequivocally. A mechanism for the isomerization of 11 to 12 is proposed.

An analytical analysis using a linear elastic composite cylinder formulation shows that adapative SMA elements in a composite cylinder can be used to actively reduce peak tensile hoop stresses in the composite cylinder inner walls. Lower peak hoop stresses are produced by using the active SMA elements to create a compound cylinder effect. Significant reductions in peak tensile stresses can be accomplished using the adaptive compound cylinder effect. The resulting hoop stresses in the thick-wall composite are also more efficiently loaded through-out the cylinder wall thickness. With the adaptive hybrid composite materials, high-pressure composite cylinders can be produced which have lower levels of radial expansion. A model for the adaptive composite material cylinder and representative stress states for various composite materials is presented. Parametric studies were performed to demonstrate the utility of the adaptive composite cylinder concept for various composite materials and pressure vessel configurations.

From these poles equations for the center-point and circle-point curves are developed. However, if a pole is infinite (the associated displacement is a pure translation), the established derivations for the pole curve equation break down. One can eliminate this problem by expressing the pole curve equation in the projective plane, because all points, including points at infinity, have finite homogeneous coordinates. In this paper, the pole curve equation is derived in the projective plane. This projection derivation is an analytic expression of Alt's graphical construction of the pole curve. The pole curve is the intersection of a pair of projective pencils of circles (one pencil for opposite sides of the opposite-pole quadrilateral) which are defined by the homogeneous coordinates of the poles. The resulting equations are applied to several problems in the synthesis of four-bar linkages. In addition the rotation curves, the locus of displacement poles for a four-bar linkage, are computed for linkages with sliding joints.

The three geometries studied include circular transverse, circular oblique, and elliptical transverse injectors, and the crossflow is at Mach 2. Planar Mie scattering images of three near-field flow planes produced substantial information about the flowfield created by each injector. In addition to global flowfield characteristics, the Mie scattering images provided transverse and lateral penetrations for each injector. Instantaneous and time-averaged information concerning the structural organization of the flowfields was obtained. Results demonstrate increasing jet penetration in the transverse direction with increasing jet-to-freestream momentum flux ratio. Penetration of the oblique jet is appreciably less in the near-field compared to the two transverse jets due to the reduced component of momentum in the transverse direction. The transverse elliptic jet appears to spread more quickly in the lateral direction than the other two jets, suggesting that some type of axis-switching phenomenon occurs. Large-scale structures at the interface between the jet and freestream fluids are shown for the two transversely oriented jets, while small-scale eddies are prominent in the oblique jet flowfield. Near-field mixing appears dominated by these eddies and the counter-rotating structures that develop in the streamwise direction. C1 USAF,WRIGHT LAB,POPT,TAITECH GRP,WRIGHT PATTERSON AFB,OH 45433.

To report several cases of arthritis seen in children after infection with Group A betahemolytic Streptococcus (GABHS) which were not associated with carditis or other major manifestations of the Jones Criteria for acute rheumatic fever (ARF); and to analyze the literature to determine these patients' potential risks for the subsequent development of rheumatic heart disease. Methods. A retrospective chart review was performed of all patients seen in a pediatric rheumatology clinic from January, 1990 to December, 1992. Results. Four patients were identified with poststreptococcal reactive arthritis (PSReA) and no carditis. Their arthritis had an acute onset, tended to have a longer duration than the arthritis typically seen in ARF, and in most instances did not respond promptly to therapy with aspirin or nonsteroidal antiinflammatory agents. In some patients, there was no history of sore throat or fever. Diagnosis of PSReA was made by serologic testing, Cardiac evaluation in all 4 patients was negative. Conclusion, PSReA should be considered in the differential diagnosis for any pediatric patient with the acute onset of arthritis, whether the arthritis is the classic migratory polyarthritis typically seen in ARF or not. Throat culture and serologic testing for streptococcal infection should be performed on these patients. If recent GABHS infection is confirmed, cardiac evaluation, including echocardiogram, is warranted. Both ARF and PSReA occur after GABHS infection, but the precise relationship between these 2 entities is unclear. Longterm follow up of pediatric patients with PSReA in previous reports have shown that a certain percentage of them upon subsequent GABHS infection develop carditis. Until the specific risk factors (either host or bacterial characteristics) for developing subsequent carditis are better delineated, antibiotic prophylaxis similar to that used in ARF should be considered in patients with PSReA.

The refractive and diffractive phenomena are studied in the resonant and the optical regimes. The numerical solutions are generated by solving the three-dimensional Maxwell equations in the time domain using an upwind-biased finite-volume algorithm. The numerical results are third order accurate in space and second order accurate in time. The simulations are validated on simpler shapes, including a cylinder and a sphere, for which the solutions are well known. The scattered field is then described for the re-entry vehicle in the resonant and optical regimes. The numerical results demonstrate that accurate radar cross sections can be obtained by implementation of consistent boundary conditions de, eloped for a perfectly conducting scatterer.

One method of quantifying this angular-dependent performance is through the average optical transfer function (OTF). An equally important measure is the variance of the OTF. The variance is used together with the average OTF in the definition of a signal-to-noise ratio (SNR). Knowledge of the SNR is essential for determining the spatial frequency limit of image restoration. We present a diffraction-based method of computing the object-angle-dependent OTF SNR for an adaptive-optics system. The SNR is computed with normalized correlation functions that are valid for a wide range of atmospheric turbulence profiles and beacon-object angles. The SNR results are presented for observation angles out to 6 times the isoplanatic angle as defined by Fried [J. Opt. Soc. Am. 72, 52 (1982)].

The generalized filter may consist of any structure from a single periodic element to a multiple series of filter elements; identical or similar filter elements may occur two or more times and may be spatially separated, forming optical cavities having one or more optical lengths. Here a cavity is defined as the space between identical or similar filter elements. Special cases of the generalized filter include singularly modulated quarter-wave-stack, sinusoidal (rugate), and Fabry-Perot filters as well as multiple-cavity high-order HTC filters. The individual filter elements of the last-named type have low-to-moderate reflectivity and may have either stepwise constant or sinusoidal refractive-index modulation. Prior calculations of HTC filter spectra used matrix methods; we develop an alternative perturbation approach. C1 UNIV DAYTON,RES INST,DAYTON,OH 45469.

During a rework operation thermal loads were imparted to the bearing by the hands of a bearing technician. A worst case analysis was employed by assuming a three-minute dwell time and diametrically symmetric thermal loading. A numerical model was used together with experimentally measured contact temperature to determine the temperature fields throughout the bearing outer ring. Next, diametric displacement solutions were variationally derived for two mathematical approximations using Hamilton's principle and assuming thin ring behavior. Alternatively diametric deflections were calculated using a finite element model (FEM) constructed for the bearing outer ring. Then the solutions yielded by the finite element and two analytic techniques were compared to diametric expansion data found experimentally. This analysis yielded vertical expansions in the bearing outer ring's diameter that would be problematic for some bearings during the rework procedure; several recommendations were given to alleviate the problem.

Tensile testing of both round and flat specimens in vacuum indicated a change in deformation behavior from 25 degrees C to 450 degrees C. Observations suggested that this change in deformation behavior occurred within the alpha(2) phase. Failure initiation at 450 degrees C and above was by a ductile process and was associated with the B2 phase. Above 600 degrees C and at high strains, plastic deformation occurred predominantly in the B2 phase. Strain localization was observed above 600 degrees C and found to be due to the lower work-hardening rate of the B2 phase. Strain localization at slip band intersections with prior beta grain boundaries resulted in rapid strain accumulation in the B2 phase. Alignment of secondary alpha(2) laths with the tensile axis at high deformation levels appeared to inhibit shear band localization between voids due to a lack of participation of the alpha(2) phase in deformation.

Respiration is not merely breathing, but intense and complex metabolic events including oxygenation and excretion of wastes such as carbon dioxide. The two major interrelated systems that are responsible for the release of metabolic wastes and byproducts are the respiratory system, including the upper airway and lungs, and the renal system. In this article, we will be concerned primarily with the exchange of gases and the effect of pathological alterations on these processes. Acute dysfunction of the respiratory system can have a major impact on the mother and fetus and can result in an increase in maternal-fetal morbidity and mortality.

In contrast to arteriovenous fistulas (AVFs), AVMs are congenital lesions with multiple large feeding arteries, a central nidus, and numerous dilated draining veins. Management of AVMs of the orbit may be difficult due to the threat of hemorrhage, vascular occlusion during treatment, and collateral damage to surrounding organs. We managed AVM of the orbit and periorbital tissues in four patients. Neuroimaging studies, clinical decision making, operative experience, and longterm postoperative results were retrospectively reviewed. Four cases of AVM of the orbit and periorbital tissues were successfully treated with preoperative embolization and subsequent excision of the central nidus of the AVM. There was no evidence of recurrence in any of the cases over follow up ranging from 2 to 5 years. We conclude that identification of all arterial feeders, from both internal and external carotid systems, is critical in developing a therapeutic plan. AVMs may be treated by surgical excision alone, or embolization alone. However, in the hands of an experienced interventional neuroradiologist and an appropriately chosen surgical team, most AVMs can and should be treated by a combined approach of preoperative embolization followed by surgical excision of the vascular mass. The goal of therapy is closure of the low-resistance shunt. C1 MED COLL WISCONSIN,ORBITAL & OCULOPLAST SECT,MILWAUKEE,WI 53226. MASSACHUSETTS EYE & EAR INFIRM,EYE PLAST & ORBIT SERV,BOSTON,MA 02114.

To achieve this resolution, a wide field of view (FOV) phased array imaging system must accurately control phase and must superimpose the images from all telescopes to within a fraction of a resolution element over the whole FOV simultaneously. We built a test bed called the Multipurpose Multiple Telescope Testbed (MMTT). It consists of four 20-cm-aperture telescopes phased together with a +/- 15-arcmin FOV. It has no mount and is designed for laboratory use only, We present a brief description of the MMTT and then describe performance tests and results. The phasing and image superpositioning accuracy of the array were measured using star tests.

An ultrashort laser source with 0.5-ps pulse width and 602-nm wavelength was employed. The transmissivities of the various 1-cm-thick solution samples have been measured as a function of the beam intensity as well as of the solute concentration. The measured results can be fitted on the assumption that two-photon absorption is the only predominant mechanism causing the observed optical-limiting behavior. Based on the intensity-dependent transmissivity measurements, the molecular two-photon absorption coefficients for the four compounds are presented.

Pediatric adenoidal obstruction of the nasal airway is associated with significant morbidity and is a frequent indication for surgery. Because efficacious medical alternatives to adenoidectomy are lacking, we assessed the potency of standard-dose topical nasal beclomethasone in reduction of adenoidal obstruction of the nasal airway. Methods. Seventeen children, 5 to 11 years of age, exhibiting chronic obstructive nasal symptoms and a group mean (+/-SE) adenoid/choana ratio of 91 +/- 1% on rhinoscopic examination, completed an 8-week, double-blind, placebo-controlled crossover study of standard-dose aqueous nasal beclomethasone (total 336 mu g/day) in the treatment of adenoidal hypertrophy. In a 16-week, open-label, follow-on study, subjects received beclomethasone 1 spray in each nostril twice daily (168 mu g/day). Results. Over the initial 4 weeks, improvements in the mean adenoidal obstruction of the choanae were significantly greater in the group receiving beclomethasone than in the group receiving placebo (right, -14.0% vs. +0.4%, P = .0002) (left, -15.0% vs. -2.0%, P = .0006). In the subsequent crossover 4 weeks, a significant beclomethasone carryover effect resulted in further adenoid size reduction in both treatment groups. All patients demonstrated a decrease in adenoid size with beclomethasone treatment, compared with a mixed response to placebo. Over the full 8-week crossover study, the mean (+/-SE) obstructive symptom score after beclomethasone treatment (20.5 +/- 3.0) was significantly improved compared to patients' initial (43.1 +/- 2.9) and placebo scores (31.1 +/- 4.2, P less than or equal to .05), despite the active drug carryover effect into the placebo treatment period. Significant improvements in adenoidal obstruction and symptom scores over the g-week crossover study were enhanced in the subsequent 16-week open-label period (P = .0001). By 24 weeks, an 82% reduction in group mean nasal obstruction symptom score accompanied a 29% mean reduction in adenoid/choana ratio. No clinical or demographic characteristic predicted a patient's degree of response to treatment. Conclusions. Properly administered aqueous nasal beclomethasone in standard doses can significantly reduce adenoidal hypertrophy and nasal airway obstructive symptoms in children.

To identify clinical factors in term neonates with severe respiratory failure that predict which neonates are unlikely to respond to high-frequency oscillatory ventilation (HFOV). Design. This was a retrospective review of patient charts and medical records. Patients. We studied 190 newborns treated with HFOV between July 1985 and December 1992. All patients were at least 35 weeks' estimated gestational age and had severe respiratory failure, defined as arterial to alveolar oxygen ratio (a/A ratio) of less than 0.2 or the need for peak inspiratory pressure greater than 35 cm H2O on conventional ventilation. Results. Of the 190 patients, 111 (58%) responded to HFOV (HFOV responders), and 79 (42%) were placed on extracorporeal membrane oxygenation (ECMO) after HFOV failed to improve gas exchange (nonresponders). The two groups were similar in gender and birth weight. Factors associated with failure of HFOV to produce a sustained improvement in gas exchange were a diagnosis of congenital diaphragmatic hernia and more severe respiratory compromise as assessed by admission blood gas. Stepwise logistic regression analysis showed that a diagnosis of congenital diaphragmatic hernia/lung hypoplasia (CDH/LH) and the a/A ratio at initiation of and after 6 hours of HFOV were the only significant independent predictors of the need for ECMO. Among all the patients, the presence of CDH/LH or an initial a/A ratio of 0.05 or lower yielded a sensitivity of 74% and specificity of 77% in correctly identifying neonates in whom HFOV failed to produce a sustained improvement in oxygenation. When neonates with CDH/LH were excluded from analysis, the most significant predictor of failure of HFOV was the a/A ratio after 6 hours of HFOV. In neonates without CHD/LH, a 6-hour a/A ratio of 0.08 or lower discriminated responders from nonresponders tie, treatment with ECMO) with a sensitivity of 77% and specificity of 92%. Conclusions. In our patients, the presence of CDH/LH, severe respiratory failure (a/A ratio 0.05 or lower) at initiation of HFOV, and lack of improvement in oxygenation (a/A ratio 0.08 or lower after 6 hours of HFOV) were associated with failure of HFOV and treatment with ECMO. This information should help other centers to identify neonates who are at the greatest risk for requiring ECMO support and thus allow prompt transfer to an ECMO center.

Bond lengths and angles are in good agreement with those found from a previous X-ray crystallographic study of a similar model compound. Based on the calculated torsional potential, the discrepancy between theoretical and experimental phenyl torsions is attributed to crystal packing forces. The calculated torsion barrier is three to five times greater than in previous semi-empirical AM 1 molecular orbital calculations. Calculations were performed with the 6-31G* basis set and the rotation barrier was corrected for electron correlation employing second-order Moller-Plesset perturbation theory.

The Satellite Modeler, Omniview true 3D, and Synthetic BattleBridge projects were undertaken to develop and investigate the interfaces and autonomous agents required to effectively support users of the Distributed Simulation Internet, The Satellite Modeler emulates the near-Earth space environment and portrays models of satellites moving in their correct orbits around the Earth, The motion of the satellites is broadcast to users of the DSI, The Satellite Modeler is intended to function as a training and operational aid for orbital analysts and to help them understand key spatial relationships for satellites in near-Earth orbit, The Omniview project was undertaken to provide interactive control and manipulation of a true 3D image and to thereby assist the user in understanding the activity within the DSI-hosted virtual environment, That project developed an interface that provides the Omniview user with the ease of use that a window, icon, mouse, and pointer GUI interface provides to users of 2D displays, The Synthetic BattieBridge is a system that, like the Omniview, portrays a DSI-hosted virtual environment but does not act in it, The Synthetic BattleBridge is designed to support users in making accurate and timely decisions by providing several different types of cognitive support for understanding and analyzing the activity in a battlespace, In this paper, we briefly describe each project and present some observations and conclusions we have drawn based on our experience with them.

In this research, we consider a special class of bandlimited 1-D and 2-D signals which have a multiband structure in the frequency domain, and propose a new reconstruction algorithm to exploit the multiband feature of the underlying signals. The concept of the critical value and region is introduced to measure the performance of a reconstruction algorithm. We show analytically that the new algorithm performs better than the MMSE estimator for band-limited/multiband signals in terms of the critical value and region measure. Finally, numerical examples of 1-D and 2-D signal reconstruction are given for performance comparison of various methods.

Emphasis is placed on: the distinction between eruptive (Class II) flares and confined (Class I) flares; and the underlying similarity of eruptive flares inside (two-ribbon flares) and outside (flare-like brightenings accompanying disappearing filaments) of active regions. A list of research questions/problems raised, or brought into focus, by the new paradigm is suggested; in general, these questions bear on the interrelationships and associations of the two classes (or phases) of flares. Terms such as 'eruptive flare' and 'eruption' (defined to encompass both the CME and its associated eruptive flare) may be useful as nominal links between opposing viewpoints in the 'flares vs CMEs' controversy.

The HBT base and collector currents accounting for the variation of the conduction and valence bands due to the presence of W-G and W-1 are also calculated. It is shown that including W-G and W-1 actually degrades the HBT current gain at low current 0 less than or equal to W-G less than or equal to 300 Angstrom or W-1 = 0 and 150 Angstrom less than or equal to W-G less than or equal to 300 Angstrom are used.

The polymer forms a two-dimensional lattice of nematic liquid crystalline structure, An orthorhombic unit cell with cell parameters of a = 7.87 b = 3.37 c = 11.97 Angstrom was determined from the fiber diffraction pattern. In thin films, the rigid chains spontaneously form a layered structure across the film thickness, but in a very unusual manner, i.e. the very large molecular plane is standing perpendicularly to the film surface plane. The results are identical to our recent results of poly (p-phenylene benzobisthiazole) (PBT) film[7]. The polymer, however, lost its anisotropic order upon extrusion into a film and resulted in a fiber-like structure. C1 UNIV DAYTON,DEPT CHEM,DAYTON,OH 45469. UNIV DAYTON,RES INST,DAYTON,OH 45469.

The XM46 formulation contains hydroxylammonium nitrate, triethanolammonium nitrate, and water. Male and female Sprague-Dawley rats received XM46 in drinking water containing 2.0, 1.0, 0.2, or 0.0 g XM46/liter throughout a 90-day study. Mating occurred following 14 days of treatment. One-half the male rats per group were necropsied after 28 days of treatment; the remaining males and all dams were necropsied following 90 days of treatment. No mortality occurred in any of the parental animals during the study. The study did not demonstrate any adverse effects on reproduction or litter parameters. Hemolytic anemia and methemoglobinemia were common in both sexes of rats. Splenomegaly was found in both sexes; in male rats as early as 28 days. Exposures via drinking water containing XM46 for 90 days did not result in any decrease in reproductive performance in male or female rats, but it did result in clinical signs of hemolytic anemia at doses as low as 17 mg/kg/day.

Unilateral do-not-resuscitate policies presume that cardiopulmonary resuscitation is a medical therapy and that physicians have no obligation to undertake a medical therapy that does not offer achievable and appropriate goals. Four do-not-resuscitate policies from U.S. hospitals and some of the significant published proposals are reviewed. We conclude that anything other than a physiologic definition of futility is indefensible because of imposed value judgments, imprecise definitions of quantitative and qualitative futility, inexact data, lack of certitude of economic benefit, and the role of autonomy for the patient and physician.

The elevated temperature sample displayed anomalous yield behavior, confirming the previous findings. Dislocation structures in the deformed samples at RT and 873 K, respectively, were observed by TEM. The micrographs for both RT and 873 K show long, partial dislocation loops of [101] superdislocations. However, dislocation dissociation behavior at the two temperatures was quite different. At room temperature, the(101] dislocations dissociated into a 1/6[112] plus a 1/6[5 ($) over bar 14] dislocation connected by an SISF, whereas at elevated temperature, a dissociation involving two 1/2[101] dislocations linked by an anti-phase boundary (APE) was observed. These observations suggest that at elevated temperature, a Kear-Wilsdorf or a ''roof-type'' barrier is responsible for the anomalous flow stress. These results and their impact on the overall deformation behavior of gamma titanium aluminides will be discussed.x C1 UNIV CINCINNATI, DEPT MAT SCI & ENGN, CINCINNATI, OH 45221 USA.

The observations indicate that a(011) edge dislocations decompose into two separate a(010) dislocations along the edge orientation, and that the overall shape of a(011) dislocation loops is non-planar. The embedded atom method has been used to study the energy and stability of a(011) edge dislocations, and the effects of the stress state and temperature on the dislocation core structure and mobility. A possible mechanism for the motion of a(011) dislocations will be discussed, and related to the fracture and deformation behavior of NiAl in the hard orientation.

Heat treatments were used to generate both a nearly fully lamellar microstructure (grains of alpha(2)-gamma lamellae) and a duplex microstructure (equiaxed gamma and lamellar grains) to span the wide range of microstructural conditions available through thermomechanical processing of these alloys. Fatigue crack growth tests using load-shedding threshold and constant-load-amplitude techniques were conducted at room temperature, 600 degrees C (below the ductile-to-brittle transition temperature (DBTT)) and 800 degrees C (above the DBTT). Results show that the fatigue crack growth resistance of the lamellar microstructure is superior to that of the duplex microstructure. The nature of fatigue crack advance depends strongly on microstructure, which explains, at least in part, the differences observed in crack growth rates for the lamellar and duplex microstructures. Fractography was conducted to identify the dominant crack growth mechanisms in both the lamellar and duplex microstructures. C1 UNIV DAYTON, RES INST, DAYTON, OH 45469 USA.

Two different microstructures, i.e. duplex (grain size, 20 mu m) and fully lamellar (grain size, 300 mu m), were produced, through two-step forging and subsequent heat treatments, giving similar yield strengths at room temperature. The fracture strains at room temperature were about 1.1% and 2.9% for the materials with the fully lamellar and the duplex microstructures respectively. At 600 degrees C, the duplex material shows a 15% higher fatigue strength than that of the fully lamellar material. At this temperature, the gamma alloy of both microstructures reaches high ratios of the fatigue strength at 10(7) cycles to the ultimate tensile strength (UTS), i.e. about 0.95. At 800 degrees C, the fully lamellar material exhibits higher fatigue strength values above 10(5) cycles, and both microstructures result in a two-stage behavior, in contrast to the test at 600 degrees C. The second stage features the characteristic conventional fatigue behavior, with a broad amplitude stress range, while the first stage is characterized by a narrow band of fatigue stress levels near the UTS. The fracture modes for the duplex material showed a general trend from transgranular to intergranular failure with increasing temperature. For the fully lamellar material, a change from predominantly translamellar failure to a mixture of inter lamellar and translamellar failure was observed, resulting in a microscopically and macroscopically rough fracture surface. The strain rate sensitivity of the fully lamellar material was negligible in the temperature range tested. C1 UES, DIV MAT RES, DAYTON, OH USA.

The alloys represent compositions from three classes of Ti alloys which have been considered as matrices for titanium-matrix composites. Several tests of each alloy were performed at various maximum stresses, all with a stress ratio of 0.05, a 3 min cycle period, and a temperature cycle of 150 degrees C to 650 degrees C. The fatigue lives are compared evaluating S-N behavior and fracture characteristics. Ln general, the behavior of the Ti-l 51Mo-2.6Nb-0.2Si alloy was governed by higher toughness compared to the other two alloys, and the Ti-13Al-31Nb alloy demonstrated improved performance over the Ti-14Al-21Nb alloy. A correlation with existing composite data was noted. The correlation is based on calculated micromechanical stresses in the matrix of the composites and applied stresses on the monolithic materials.

Noise covariances are derived for these type of data, including the effects of photon noise and CCD read noise. The effectiveness of support constraints in achieving noise reduction is discussed in terms of these noise properties and in terms of the types of algorithms used to enforce the support constraint. Both a convex-projections and a cost-function minimization algorithm are used to enforce the support constraints, and it is shown with the use of computer simulations and field data that the cost-function algorithm results in artifacts in the reconstructions. The convex-projections algorithms produced mean-square-error decreases in the image domain of approximately 10% for high light levels but essentially no error decreases for low light levels. We emphasize images that are well resolved by the telescope and adaptive-optics system. C1 USAF,INST TECHNOL,DEPT ENGN PHYS,WRIGHT PATTERSON AFB,OH 45433.

The problem is considered at large Reynolds number (based on x), away from the leading edge. We derive a simple non-similar analytic solution of the problem for which the interface height is proportional to x(1/4) and the water and air flow satisfy the Blasius boundary layer equations, with a linear profile in the water and a Blasius profile in the air. Numerical studies of the initial value problem suggest that this asymptotic non-similar air-water boundary layer solution is a global attractor for all initial conditions.

The full three-dimensional mass-averaged compressible Navier-Stokes equations are solved with a high-resolution implicit finite-volume scheme. Turbulence closure is achieved with variations of the Baldwin-Lomax algebraic model. Excellent agreement with experimental data is observed for plate surface pressure. However, accurate heat transfer rates are obtained only near the plane of symmetry. Some quantitative details are dependent on the manner in which the turbulence model is implemented, Within this limitation, the overall computed mean flow structure remains similar and mesh independent and compares well with available field surveys. The incoming flat plate boundary layer separates along the entire spanwise width and does not reattach in the domain of computation. Beneath the separated boundary layer are a vortex interaction with an off-surface stagnation point, a centerline longitudinal vortex, and an entrainment flow originating from the essentially inviscid stream near the fin leading edge.

Materials and Methods: A written survey instrument was sent to all active duty Air Force dentists and lawyers. The survey asked individuals to voluntarily and anonymously give information regarding positive tuberculin skin testing which was subsequently treated with antituberculosis medication. Only positive responses which occurred during the time the respondent was practicing as a dentist or lawyer in the Air Force were counted. Significant exposures were considered to have occurred in those persons who were evaluated by a physician and actually put on a course of antituberculosis medication. Results: The dentists returned 82.7% of the 1256 surveys sent, of which 2.37% indicated a significant exposure. The lawyers returned 79.6% of 1321 surveys, of which 1.47% were positive for significant exposure. Chi-square analysis indicated no significant difference between the two groups (P = 0.14).

The dual perfused human placental model was used to elucidate the factors governing the placental transfer of bupivacaine. Methods: Bupivacaine transfer was studied using the recirculating (closed) model and the single pass (open) model. Single placental cotyledons were perfused with either heparinized Krebs-Ringer's buffer (KRB) supplemented with human albumin (fetal and maternal circuits) or 100% fresh frozen plasma (maternal circuit) to control the bupivacaine protein binding in those circuits. In the open model, bupivacaine clearance was compared before and after being subjected to either increasing concentrations of bupivacaine or its structural analog, mepivacaine. Results: For those studies in which the maternal and fetal protein binding was equal, the maternal to fetal (M --> F) transfer was significantly greater (P < 0.05) than that in the fetal to maternal (F --> M) direction. When the perfusates were modified to simulate actual in vivo plasma protein concentrations, bupivacaine transfer was shown to be related to the degree of protein binding found in the two circuits. In the open studies, bupivacaine transfer was similar at all concentrations investigated, unaffected by mepivacaine, and related to the pH of the fetal perfusate. A concentration effect was seen within the placental tissue at the end of the experiment. Conclusions: Bupivacaine placental transfer characteristics suggest passive diffusion rather than active drug transport and appear to be influenced by the maternal and fetal plasma protein binding, fetal pH, and placental uptake.

Protocatechuate accumulated transiently when succinate-grown cells were transferred to media containing m-NBA. Respirometric experiments indicated that the conversion of m-NBA to protocatechuate required 1 mol of oxygen per mol of substrate. Conversions conducted in the presence of O-18(2) showed the incorporation of both atoms of molecular oxygen into protocatechuate. Extracts of m-NBA-grown cells cleaved protocatechuate to 2-hydroxy-4-carboxymuconic semialdehyde. These results provide rigorous proof that m-NBA is initially oxidized by a dioxygenase to produce protocatechuate which is further degraded by a 4,5-dioxygenase.

On separate days, each monkey attempted six work/rest cycles (10 min work: 1 min rest) at 15, 25, and 35 degrees C (Tdb), vapor pressure < 10 mm Hg. Core temperature (Tco), body weight (BW) and blood samples were taken immediately before and after exercise. Excessively high heat storage rates dictated that the 35 degrees C trial he limited to three work/rest bouts, The change in Tco during exercise was significantly greater in the 35 degrees C trial than during the 15 and 25 degrees C work bouts. Sweat rate, as determined by the change in BW over time, was also significantly greater during the 35 degrees C trial as compared to the IS and 25 degrees C trials, Glucose levels (mean +/- SE) declined significantly during exercise from 4.35 +/- 0.1 and 4.58 +/- 0.4 mmol to surprisingly low levels of 1.67 +/- 0.2 and 1.76 +/- 0.2 mmol in the 15 and 25 degrees C trials, respectively. increases in blood lactate, glycerol, and triglycerides were observed independent of environmental temperature, Free fatty acids increased during exercise in the 15 and 25 degrees C trials but declined slightly during the shorter 35 degrees C trial. The findings of this study indicate that the increased heat storage observed at higher environmental heat loads appears to substantially limit the amount of work these primates can perform, possibly the result of a limited sweat production capacity, Additionally, plasma glucose following exercise decreased to levels not typically seen in humans, The general metabolic profile in these primates was otherwise similar to that observed in humans at this work level.

This study reviews the physiological, cognitive, behavioral, and psychological effects of smoking withdrawal as they relate to Crying performance. The variety of research designs, methodologies, and subject groups is discussed. Findings suggest that heart rate, arousal, vasoconstriction, vigilance, concentration, and energy increase with nicotine use; stress and irritability are reduced with smoking. Withdrawal, on the other hand, produces a decrease in carboxyhemoglobin, digit recall, serial addition/subtraction, and job satisfaction; blood pressure, depression, absenteeism, caloric intake, craving, aggressiveness, confusion, and impulsivity increase with withdrawal. Severity of withdrawal symptoms varied, but most studies report psychological, and/or physiological responses to nicotine withdrawal. The conflict between health and performance is discussed and suggestions for future directions are offered. C1 AOCN,AL,BROOKS AFB,TX 78235. USAF,SCH AEROSP MED,BROOKS AFB,TX 78235.

Over 650 patients enrolled in a large anticoagulation clinic were studied during two time periods corresponding to the use of the PT ratio versus the WR to guide anticoagulant therapy, with over 400 patient-years of follow-up for each time period. The rate of bleeding complications using the PT ratio to guide therapy was 6.7% (1.2% major, 5.5% minor) per patient-year, compared with 2.9% (0% major, 2.9% minor) using the INR (p = 0.02). The rate of thromboembolic complications was 1.0% using the PT ratio, compared with 0.2% using the INR (p = NS). Therapy monitored with the INR required 19.8 visits per year, compared with 20.7 visits per year using the PT ratio. We conclude that the INR should be used to monitor oral anticoagulant therapy in an effort to reduce bleeding complications while maintaining an acceptable rate of thromboembolic events.

Location of facilities and allocation of equipment to facilities is an important decision making area in service logistics. Earlier models [1-3] developed to address this issue either consider all demands to be covered or all demands cannot be covered because of equipment unavailability. Most of the models developed in the literature only consider single type of equipment usage. We develop a model for the multiple facility, multiple levels of equipment problem called the Multiple Equipment Multiple Cover facility Location-Allocation problem (MEMCOLA) which considers maximal coverage of demand, including multiple coverage of demand by equipment of a specific type, given that each equipment has a certain probability of being unavailable. MEMCOLA simultaneously locates a given number of facilities and allocates different types of equipment to the facilities. C1 USAF,INST TECHNOL,DEPT LOGIST MANAGEMENT,WRIGHT PATTERSON AFB,OH 45433.

However, these studies only examined a limited number of muscle groups and did not assess subjective tension levels. The present study evaluated a group of tension-type (n = 43) and migraine and tension-type (n = 30) headache patients. Measures were obtained at five muscle sites (frontalis, temporalis. masseter, splenius capitis, and trapezius) for patient ratings of headache pain, patient ratings of muscle tension, and electromyogram recordings cross-sectionally. Neither subjective pain nor tension ratings were found to be significantly related to electromyogram levels. The site-specificity relationship between chronic headache pain, subjective report of muscular tension, and electromyogram levels remains unclear. C1 KEESLER MED CTR,BILOXI,MS.

Expressions are obtained for the linear and quadratic changes in index and absorption coefficients of asymmetric and symmetric quantum well structures. The triple resonance term does not contribute to the quadratic Kerr effect for a symmetrical well in an expansion about F = 0. In the second part of the paper, these results are applied to several types of modulators. First we consider two kinds of silicon/silicon-germanium high-barrier asymmetric quantum well structures at 1.55 mu m. For the step well, the dominant triple resonant term of the quadratic Kerr effect adds to the linear electrooptic effect (LEG) to yield an intensity extinction ratio of 15 dB in switching from F = +8 V/mu m to -8 V/mu m and a very small insertion loss of 0.04 dB, for a modulator length of 200 Csm and for narrow linewidths (FWHM 7.6 meV). For the case of asymmetric barriers confining silicon wells, a comparable insertion loss is obtained but with an extinction ratio of 44 dB for FWHM = 20 meV, a clearly superior performance. For symmetrical silicon-based wells, the double-resonance modulation, though small at lambda = 1.55 mu m, is appreciable at lambda = 10,6 mu m. For the Kerr effect in symmetrical gallium arsenide wells at lambda = 10.6 mu m reported by Sa'ar et al., we show that it is the double-resonance term which yields the six order of-magnitude enhancement with respect to bulk and that an even larger enhancement of the Kerr effect can be obtained in an asymmetric GaAs structure together with the LEG.

Each modality has its proponents, but, to our knowledge, no comparative studies have been conducted in animals. We used biochemical and histological analysis to compare these methods of treatment in an experimental model. The right hind knee of thirty goats was injected with 1 x 10(5) Staphylococcus aureus bacilli. The left hind knee mas not inoculated and served as the normal control. Seventy-two hours after inoculation, a two-week course of treatment with intramuscular administration of cefuroxime sodium, either alone or in combination with another mode of treatment, was initiated in each of five groups. The cartilage was evaluated histologically with biochemical, enzymatic, and interleukin-1 analyses. Despite the early therapeutic intervention, on the average, there was a 25 per cent loss of uronic acid (t test, p < 0.001) and a 43 per cent increase in neutral protease activity (signed-rank test, p = 0.003) in the treatment groups. There were no significant intergroup differences with regard to the histochemical-histological rating or the levels of uronic acid, neutral protease, or interleukin-1. CLINICAL RELEVANCE: The treatment of septic arthritis, excluding that in the hip joint, is changing, with an emphasis on less invasive operative techniques. In the present study, early treatment with an appropriate antibiotic and such treatment with arthrotomy, arthroscopy, arthroscopy with debridement, or needle aspiration produced indistinguishable results. Our findings suggest that, if an infected knee joint is diagnosed early and appropriate antibiotic therapy is initiated immediately after the diagnosis, any of the standard treatment modalities can effectively eradicate the infection, with minimum damage to the cartilage.

In previous publications, the clinical, radiographic and immunologic findings in the family were presented. 38 permanent teeth from the 2 siblings were prepared for microscopic examination, 11 for light microscopy (LM), and 27 for scanning electron microscopy (SEM). In addition, 8 healthy teeth obtained from 2 patients requiring extractions for orthodontic treatment served as controls. LM observations on healthy teeth revealed cementum with normal structural appearance which exhibited a mosaic or mogul-like pattern with SEM. In LAD specimens, cementum apical to the dentogingival junction exhibited resorption lacunae and areas of poor structural definition characterized by aplasia and hypoplasia (hypomineralization). Areas of hypoplasia presented as distinct irregular surfaces with a pebbly or globular-like appearance. Alteration in cementum formation and maturation may play a role in the etiology of early-onset periodontitis. C1 BAYLOR COLL DENT,DEPT PERIODONT,DALLAS,TX.

Reflection high-energy electron diffraction (RHEED) measurements were used to investigate the growth behavior of GaAs over a wide temperature range of 300-550 degrees C. Both group III- and group V-induced RHEED intensity oscillations were observed, and actual V/III incorporation ratios on the substrate surface were established. Thick GaAs epitaxial layers (2-3 mu m) were grown at different substrate temperatures and V/III ratios, and were characterized by the standard van der Pauw-Hall effect measurement and secondary ion mass spectroscopy analysis. The samples grown at substrate temperatures above 490 degrees C showed n-type conduction, while those grown at substrate temperatures below 480 degrees C showed p-type conduction. At a substrate temperature between 490 and 510 degrees C and a V/III ratio of about 1.6, the unintentional doping concentration is n similar to 2 x 10(15) cm(-3) with an electron mobility of 5700 cm(2)/V.s at 300K and 40000 cm(2)/V.s at 77K.

These patients may present with chronic pelvic pain or pelvic masses and may require surgery to confirm or exclude the diagnosis. In this report we describe the successful use of the gonadotropin releasing hormone agonist (GnRH-a) stimulation test to identify the presence of functioning ovarian tissue in three women with ovarian remnant syndrome who presented for evaluation of persistent chronic pelvic pain. In these cases the endogenous gonadotropin flare was able to stimulate the production of significant quantities of estradiol to confirm the diagnosis. The GnRH-a stimulation test may be a useful adjunct in the evaluation of women at risk for ovarian remnant syndrome prior to proceeding with surgery.

Ninety-eight sets of specimens from previously untreated patients with an oral cavity or oropharyngeal tumor and a simultaneous cervical metastatic deposit were analyzed. Normal mucosa and cervical lymph nodes were processed identically and run as controls, All patients underwent surgical resection at Wilford Hall USAF Medical Center or The Eye and Ear Hospital of Pittsburgh between 1980 and 1986. The specimens from 94 patients were technically adequate for interpretation. Diploid histograms in both the primary and metastatic tumors were present in 49 (52%) of 94 patients, Aneuploid histograms in either the primary or metastatic tumors were noted in 45 (47%) of 94 patients, In this group of 45 patients, the primary tumor and cervical metastasis were both aneuploid in 21 (46%), and aneuploid histograms occurred with equal incidence in either the primary or metastasis in the remaining 24 cases. No statistically significant prediction of survival could be made from any correlation with the histograms of either the primary or metastasis, The potential technical problems and limitations of flow cytometry in the determination of DNA content of formalin-fixed, paraffin-embedded tissue and the selection of patients with advanced disease warrant caution in the interpretation of results.

We describe our experience with this biologic bone cement in the reconstruction of suboccipital craniectomy defects in seven patients after vestibular schwannoma removal. With up to 2-year follow-up, cranial bone integrity has been reestablished in five patients. Dissolution of cement has occurred in dependent areas and appears to be technique related. Cranial bone contour appears dependent on the amount of cement used. The frequency of debilitating postoperative headache was reduced in these patients when compared to patients who had no reconstruction of the craniectomy defect. Reconstruction of the bony defect after suboccipital craniectomy with hydroxypatite cement is not only useful to restore cranial contour, but also appears to reduce some of the functional deficits attributed to this surgical approach.

However, it is not known whether military retirees and their dependents also report higher smoking and alcohol use compared to the general senior population, Therefore, this study examined cigarette and alcohol use in a group of military retirees (n = 1,359) and dependents (n = 983). Contrary to studies surveying active duty members and their spouses, the present study found that smoking rates and alcohol use among military retirees and dependents were similar to those reported in surveys of the general senior population, In addition, the fact that the majority of retirees (68%) classified themselves as ex-smokers suggests that these individuals may adopt more healthy lifestyles over time. Factors associated with smoking and alcohol use are also presented, along with suggestions for future research.

Arctic air, originating within the interior of British Columbia, descended into a mesoscale gap in the Coast/Cascade Mountains and then accelerated ageostrophically to the west. This gap acceleration is explained quantitatively by a three-way balance among the pressure gradient force, friction, and inertia. The flow maintained its integrity as a narrow current of high-speed air as it exited the gap and subsequently accelerated over water. Troughing in the lee of the Cascade Mountains enhanced the horizontal pressure gradient over northwest Washington; this pressure gradient approximately balanced frictional drag resulting in only minimal acceleration. Farther south the flow decelerated as the current spread out horizontally. C1 UNIV HAWAII MANOA,DEPT METEOROL,HONOLULU,HI. USAF,LAS VEGAS,NV.

Methods: Two patients with vision loss from AMD and spontaneous pigment epithelial detachment tears, involving the fovea with serous or hemorrhagic neurosensory retinal detachments, were examined clinically. The surgically excised CNVM from each patient was examined with light microscopy. Results: The authors present two patients with clinicopathologic correlation of the ophthalmoscopic, fluorescein angiographic, and pathologic findings of spontaneous pigment epithelial detachment tears. In the surgical specimens from these two eyes, the removed tissue, presumed to be the spontaneous RPE tear with CNVMs, demonstrated a fibrovascular membrane surrounding RPE with adjacent abnormally thickened basement membrane. The RPE-basement membrane complex was folded redundantly and scrolled beneath itself. Conclusion: The authors found RPE-basement membrane abnormalities and CNVMs associated with clinically evident spontaneous pigment epithelial detachment tears. These findings support the current theories of their pathogenesis. C1 WILFORD HALL USAF MED CTR,DEPT OPHTHALMOL,LACKLAND AFB,TX 78236.

Animal studies indicate that systemic administration of tyrosine in pharmacological quantities can reduce physiological and behavioral decrements induced by highly stressful conditions. The current study was designed to test the effects of tyrosine (100 mg/kg of body weight) on humans exposed to cardiovascular stress. Twenty participants were exposed to two Lower Body Negative Pressure (LBNP) sessions (-50 mm Hg for a maximum of 30 min) during each of two testing sessions of a repeated measure double-blind placebo-controlled study. The detected effects of tyrosine include an overall increase in pulse pressure (LBNP typically seduces pulse pressure) and an increase in auditory event related potential amplitude (P300-N300), an electrophysiological correlate of attention which may indicate enhanced cognitive activation.

The medical records of all patients that underwent laparoscopic cholecystectomy during 1990 and open cholecystectomy during 1989 in one hospital were reviewed. Hospital stay, hospital charges, surgeons' and anesthesiologists' fees were determined. Fifty patients from each group were contacted to determine recovery time to full activity after surgery. Those having common duct exploration and those converted to open cholecystectomy after an attempted laparoscopic cholecystectomy (n = 8) were excluded. A summary of results is included below (Table 1). In our early experience with laparoscopic cholecystectomy we found that the total charges for laparoscopic cholecystectomy were more than for open cholecystectomy when one recognizes the 1-year difference in patient accrual between the two groups. Time to full recovery was markedly reduced in patients undergoing laparoscopic cholecystectomy compared to those having an open procedure. Despite the overall increased total charge with laparoscopic cholecystectomy, the shorter recovery period allowing the patients an earlier return to full preoperative activities contributes to its cost-effectiveness when compared to open cholecystectomy. Further experience with laparoscopic cholecystectomy and refinements in management of these patients should allow for further reductions in charges for this procedure.

It compares the decisions made by McDonnell-Douglas Corporation with those of Boeing Aircraft Company in the late 1970s and early 1980s. The study concludes that strategic decisions were made based on each company's vision of its core business. This article examines the decisions of two commercial aircraft firms as they decided whether or not to introduce new technologically advanced airliners. By contrasting the decision-making process of two competitors that faced the same external and objective situations, we can determine some of the factors that explain why new technologically advanced products are or are not introduced into the market place. The time frame of this study covers the late 1970s and the early 1980s. The next section introduces the questions we ask. This is followed by a discussion of the external environment faced by the firms. Then we provide a brief history of the two companies, discuss the opportunities and risks that were involved in the decisions, and analyze those decisions. The final section presents our conclusions.

To review a contemporary series of rectal injuries occurring during radical perineal prostatectomy. Methods. Of 81 patients who underwent radical perineal prostatectomy, 9 (11%) sustained a full-thickness laceration of the anterior rectal wall, All 9 patients had a preoperative bowel preparation, although only 1 received a complete oral lavage regimen. All received prophylactic perioperative intravenous antibiotics. None had undergone prior surgery to the rectum or perineum or received prior pelvic radiation therapy. Results. In most cases injury occurred during division of the rectourethralis muscle, but in at least hive instances the injury appeared to be the result of undue posterior retraction along the rectal wall. All injuries were recognized at the time of surgery and repaired primarily. No patient had associated postoperative complications. Conclusions. Rectal injury occurs with significantly greater frequency with radical perineal prostatectomy than with the retropubic approach. However, if the rectum is adequately prepared, the injury promptly recognized and repaired, and postoperative care appropriate, the great majority of cases will not lead to attendant morbidity.

With a significantly lower incidence of pelvic node involvement, it may be possible to identify a segment of patients for whom pelvic lymph node dissection (PLND) may be omitted. This study was conducted to develop a method to select patients for whom PLND could be omitted. Methods. We analyzed serum prostate-specific antigen (PSA), clinical stage, biopsy Gleason score, and final pathologic stage in 481 men with clinically localized prostate cancer. These variables were compared to the risk of positive pelvic lymph nodes. Results. Logistic regression analysis determined that combining all three variables provided the best determination of final pathologic stage. A series of probability curves have been created to estimate the risk of positive lymph nodes in a given patient. Based on the distribution of patients in this study and using these probability functions, PLND could be avoided in up to 50% of patients with localized prostate cancer diagnosed by contemporary methods. Conclusions. In properly selected patients, pelvic lymphadenectomy can be omitted in the staging and treatment of localized prostate cancer. C1 WILFORD HALL USAF MED CTR,UROL SERV,SAN ANTONIO,TX.

A questionnaire was prepared that asked recipients-to rate each of 36 tasks selected as representing the spectrum of practice activities. There were four categories of tasks: managerial tasks, dispensing tasks, drug information tasks, and patient care tasks. Recipients rated the tasks with respect to frequency of performance and importance on separate 6-point scales. The questionnaire was mailed in May 1991 to the 225 pharmacists then serving in the Air Force worldwide. Of the 225 questionnaires, 150 usable questionnaires were returned (response rate, 67%). All the tasks in the survey were performed by at least one Air Force pharmacy officer, although the frequency of task performance varied. In particular, the frequency of many patient care tasks was low. All the tasks were perceived to have some importance, but drug information tasks were rated as being significantly more important than tasks in the other categories; patient care tasks were rated lowest in importance. The results varied with the respondents' demographic characteristics. Pharmacy officers with more years of service, more senior positions, higher rank, or an advanced degree in a field other than pharmacy tended to give responses that diverged from those of the population. A 1991 survey showed an awareness among Air Force pharmacists of the need to orient practice around patient care; however, they were not spending substantial time on patient care and tended to view it as less important than more traditional pharmacy tasks.

Uniaxial compression tests on samples with different relative densities were used to obtain the the apparent Poisson's ratio and constitutive behaviour. Microhardness tests on undeformed and deformed samples with different relative densities were used to obtain the stress intensification factor. With this information, a von Mises type yield function, modified for pressure effects, was developed and implemented into a finite element code and used successfully to model the densification of the alpha-two titanium aluminide powder.

(2) There are no obvious east-west asymmetries about the flare site for the occurrence of EP events although for given events, the early rise phase of SEP time-intensity profiles on one side of an eruptive flare may look quite different from those on the other. (3) For flare - satellite footpoint separations up to similar to 150 degrees, we obtain apparent lateral propagation speeds of electrons through the low corona of similar to 250-500 km s(-1) far certain events. Such speeds are consistent with SEP acceleration by a propagating shock wave, Thus EP events provide indirect evidence of widespread (similar to 300 degrees) coronal shocks. (4) Occasionally chromospheric Moreton waves give visible evidence of the azimuthal shock propagation required for EP events. However, such visible waves do not appear to be necessary conditions for EP events to occur. RP Cliver, EW (reprint author), USAF,PHILLIPS LAB,HANSCOM AFB,MA 01731, USA.

First, we are able to associate each of the 18 greater than or equal to 10% FDs observed at Earth (Deep River) from 1958-1991 with one or more eruptive flares located between E47 and W31 solar longitude. Second, we show that large Forbushlike decreases in the outer heliosphere can also generally be associated with strong solar eruptions lying close in helio-longitude to the affected spacecraft. Third, we identify a large shock (Delta V similar to 200 km s(-1)) and Forbushlike decrease (18%) at Pioneer 10 at similar to 50 AU in late 1989 that was not preceded by a commensurate disturbance at Voyager 1/Voyager2 located at similar to 35 AU on the opposite side of the heliosphere. We conclude that widespread modulation events result from systems of major solar/interplanetary disturbances that, in aggregate, encompass 360 degrees of helio-longitude rather than from azimuthally symmetric shocks associated with single eruptive flares or, alternatively, from collimated flows (from single or closely-spaced eruptions) that affect a wide range of longitude. We note that the documented preference for CMEs to occur at low and middle solar latitudes is consistent with the wedge-shaped barrier proposed by Van Allen and Mihalov to explain the ''inside-out'' pattern of recovery of individual modulated events observed at progressively greater distances in the heliosphere.

Quasistatic tests at strain rates of 10(-7)/sec to 10(-3)/sec were conducted using a standard material test machine. Higher strain rate tests of 1.0/sec to 300/sec were conducted in a 51-mm-diameter split-Hopkinson pressure bar (SHPB). Numerical simulations of both the static and dynamic tests were conducted through a comprehensive finite element method investigation. Experimentally observed crack patterns agreed very well with the predicted numerical responses. Both tension and compression strengths increase with strain rate and exhibit a critical strain rate beyond which large increases in strength occur. This critical strain rate is approximately 5/sec for tension and approximately 60/sec for compression. Beyond these critical strain rates, the tensile strength shows a larger percentage increase than the compressive strength. The effect of moisture on the dynamic compressive strength of concrete was also examined in the experimental study. C1 USAF, HQ CIVIL ENGN SUPPORT AGCY, TYNDALL AFB, FL USA.

They were found to independently react to APE coupled 1/2[110] pairs in the commonly observed pure screw orientation. Boron was observed to have strong effects upon the population of boundary types, grain size, and grain growth. In addition, small amounts of B completely eliminate widely extended stacking faults. It is concluded that effects of B other than influencing boundary cohesion are important. Implications with regard to Kear-Wilsdorf type locking mechanisms and deformation behaviour are discussed.

An expert system was created using Dempster-Shafer methods that effectively modeled the professional judgment of a skilled tribologist in the selection of rolling element bearings. A qualitative and symbolic approach was used, but access to simple quantitative models was provided to the expert system shell. Although there has been significant discussion in the literature regarding modification/improvement of the Dempster-Shafer theory, Shafer's theories were found adequate in all respects for replicating the expert's judgment. However, an understanding of the basic theory is required for interpreting the results. C1 USAF,MAT DIRECTORATE,WL MLIM,WRIGHT PATTERSON AFB,OH 45433.

Like other forms of glomerulonephritis, the lupus-like kidney disease observed in these animals is frequently accompanied by glomerular deposition of fibrin and increased accumulation of mesangial matrix. Because alterations in plasminogen activator inhibitor type 1 (PAI-1) expression or function may be involved in both fibrin deposition and accumulation of extracellular matrix, we have studied the effects of CR on the expression of PAI-1 in kidneys from female B/W mice fed either ad libitum or on a 40% CR diet. By immunohistochemistry and immunoblotting, we found that the glomerular levels of PAI-1 antigen were highest in older ad lib fed animals with more advanced glomerular disease. Increased levels of PAI-1 protein were paralleled by increased levels of PAI-1 mRNA in total RNA extracted from renal cortex and in diseased glomeruli as detected by in situ hybridization. CR diminished the accumulation of PAI-1 protein and reduced the expression of PAI-1 mRNA. Thus, glomeruli from animals fed ad lib showed much greater deposition of PAI-1 mRNA, and more severe histological abnormalities than animals on a CR diet. The differences between CR and ad lib animals were more pronounced in animals studied at 9 to 10 months versus those at 3 to 4 months of age. These observations indicate that the ameliorating effects of CR include diminished PAI-1 gene expression adn decreased localization of PAI-1 in glomeruli.

In the case now reported, the brachial plexus injury involved the posterior shoulder. As the delivery was spontaneous and without forceps or manual rotation, with delivery effected using only the McRobert's maneuver, it is hypothesized that maternal expulsive forces in conjunction with lodging of the posterior shoulder on the sacral promontory resulted in the injury.

Several investigators have studied sIL-2R levels in patients with Type I diabetes mellitus (IDDM), but results have been conflicting. Our primary objective in this study was to compare sIL-2R levels of children and adolescents with newly diagnosed IDDM with those of age-matched controls. In addition, sIL-2R levels in a cohort of patients were followed longitudinally for 1 to 2 years after diagnosis. Serum sIL-2R levels of 38 IDDM children and adolescents (age < 20 years) were compared with levels of 39 nondiabetic, age-matched controls. Mean sIL-2R levels declined with age (P < 0.000005), and there was no significant difference in the regression line relating age and sIL-2R levels between patients and controls. The sIL-2R levels remained fairly consistent over 1-2 years of follow up. The presence of islet cell antibodies (ICA) had no apparent effect on sIL-2R levels in children with diabetes. The sIL-2R levels were similar in magnitude among first degree relatives of patients with IDDM compared to the range of unrelated subjects. It is our conclusion that sIL-2R levels are highest during infancy and decline throughout childhood.

Some compounds are produced by incomplete combustion of fossil fuels; others are used as synthetic intermediates, dyes, pesticides, and explosives. Recent research revealed a number of microbial systems capable of transforming or biodegrading nitroaromatic compounds. Anaerobic bacteria can reduce the nitro group via nitroso and hydroxylamino intermediates to the corresponding amines. Isolates of Desulfovibrio spp. can use nitroaromatic compounds as their source of nitrogen. They can also reduce 2,4,6-trinitrotoluene to 2,4,6-triaminotoluene. Several strains of Clostridium can catalyze a similar reduction and also seem to be able to degrade the molecule to small aliphatic acids. Anaerobic systems have been demonstrated to destroy munitions and pesticides in soil. Fungi can extensively degrade or mineralize a variety of nitroaromatic compounds. For example, Phanerochaete chrysosporium mineralizes 2,4-dinitrotoluene and 2,4,6-trinitrotoluene and shows promise as the basis for bioremediation strategies. The anaerobic bacteria and the fungi mentioned above mostly transform nitroaromatic compounds via fortuitous reactions. In contrast, a number of nitroaromatic compounds can settle as growth substrates for aerobic bacteria. Removal or productive metabolism of nitro groups can be accomplished by four different strategies. (a) Some bacteria can reduce the aromatic ring of dinitro and trinitro compounds by the addition of a hydride ion to form a hydride-Meisenheimer complex, which subsequently rearomatizes with the elimination of nitrite. (b) Monooxygenase enzymes can add a single oxygen atom and eliminate the nitro group from nitrophenols. (c) Dioxygenase enzymes can insert two hydroxyl groups into the aromatic ring and precipitate the spontaneous elimination of the nitro group from a variety of nitroaromatic compounds. (d) Reduction of the nitro group to the corresponding hydroxylamine is the initial reaction in the productive metabolism of nitrobenzene, 4-nitrotoluene, and 4-nitrobenzoate. The hydroxylamines undergo enzyme-catalyzed rearrangements to hydroxylated compounds that are substrates for ring-fission reactions. Potential applications of the above reactions include not only the biodegradation of environmental contaminants, but also biocatalysis and synthesis of valuable organic molecules.

How can a group of geographically distributed agents properly allocate a set of tasks among themselves while satisfying different types of constraints? Also, in an environment of limited resources, how can agents resolve resource conflicts and effectively accomplish tasks? We have examined these two problems and have developed new techniques to promote multiagent coordination and cooperation. A novel method of negotiation allows agents to bid for tasks based upon the agents' capabilities. Furthermore, the use of a threshold value ensures that only the best agents for a task become task commanders and renders some tasks to be renegotiated as agents improve their bids. To resolve resource conflicts, a technique called 'hierarchical iterative conflict resolution' has been implemented. This allows conflicts to be resolved in an iterative manner, based upon a hierarchy of task priorities. Agents with higher priority tasks have the authority to borrow resources from agents with lower priority tasks. It ensures that higher priority tasks will be solved before those of lower priority. These new techniques were employed in a DAI testbed which simulates an air war environment. C1 ARIZONA STATE UNIV,ARTIFICIAL INTELLIGENCE LAB,TEMPE,AZ 85287.

Social contacts between pilots and flight surgeon occur in many different settings, both formal and informal, Actively flying pilots were surveyed to investigate which interactions between the flight surgeon and the pilot most effectively establish rapport. Increased patient satisfaction and increased time spent with pilots, considered together and independently, were associated with improved rapport. The informal associations that occur in the pilot's work areas, and the formal interactions that occur at safety briefings, are the most important encounters for establishing good rapport. The contacts in the flight surgeon's office are the least important encounters in establishing rapport. C1 USAF,SCH AEROSP MED,AF,BROOKS AFB,TX 78235.

Because COPD can be associated in varying degrees with ischemic heart disease (IHD), and because the consequences of hypoxia in such patients can be significant, the ground and altitude pulse oximeter readings of 24 ambulatory aeromedical evacuation patients with known or suspected IHD were recorded. Written, informed consent, as well as smoking history and respiratory spirometry were obtained preflight. Results showed a mean saturation decrease of 5.5 percentage points (95% CI: 4.5-6.4). The mean cabin altitude wets 6900 ft (range: 2500-8100). No patients experienced clinical symptoms. Of 24 patients, 3 were given supplemental oxygen when their Inflight oximetry readings consistently read below 90%. Saturation decrease did not correlate specifically with age, smoking history, the FEV1/FVC ratio, or the inflight cabin altitude, We conclude that ambulatory aeromedical evacuation patients with known or suspected IHD may demonstrate mild decreases in oxygen saturation which are not readily predicted by age, smoking history, preflight spirometry, or inflight cabin altitude. Pulse oximetry compatible with aircraft electrical systems may provide useful inflight monitoring on such patients. C1 USAF,SCH AEROSP MED,BROOKS AFB,TX 78235. USAF,YOKOTA AIR BASE,JAPAN.

We report the case of an aviator who experienced a traumatic right vertebral artery occlusion with distal embolization. Timely access to a state of-the-art neurodiagnostic evaluation, which included time of-flight magnetic resonance angiography (MBA), and standard contrast angiography, provided anatomic imaging at the time of injury and during the recuperative period, Sophisticated neurologic testing protocols at the Armstrong Laboratory's Aeromedical Clinical Sciences Division, Brooks Air Force Base, TX, assessed in-depth this individual's functional status. Consult Service evaluators then compared his performance data with current data in the Head Injury Study in Aviators (HISA) data base. MRA, in comparison with standard contrast angiography, demonstrated anatomic stability of his vascular and neurologic lesions. He demonstrated a functional capacity consistent with normal neurologic functioning in aviators which permitted recommending an occupational (flying) waiver. This case exemplified application of sophisticated ACS neurologic testing protocols to aeromedical evaluations and the use of MRA technology as ct vascular screening tool during medical followup.

Of the sample, 65% were assigned to flying squadrons, 15% to aeromedical evacuation staging units, and 20% to combat support hospitals, Indepth interviews concentrated on individual perceptions of wartime experiences, roping skills used, and significant events remembered, Thematic content analysis was used to describe, summarise, and classify data. Each nurse responded to this professional challenge in a unique way. Reactions to ct combat environment and resolution of experiences from the Vietnam War confirmed Horowitz's Stress Response Theory. Findings confirmed the notion of intensity and Post-Traumatic Stress Disorder (PTSD). Of those in this sample who served during the Tet Offensive 25% reported symptoms of PTSD. Respondents reported strong social support, maturity, nursing experience, humor, religion, and relaxation as crucial survival skills. Of the nurses interviewed, 60% cited patient care situations and threats to survival as the most significant events remembered. Serving in the Vietnam War proved their most rewarding professional experience. RP RAVELLA, PC (reprint author), SGN,HQ AETC,63 MAIN CIRCLE SUITE 3,RANDOLPH AFB,TX 78150, USA.

Therefore, a conventional metal microdialysis probe cannot be used to determine the bioeffects of electromagnetic radiation. Using fused-silica tubing, we developed an inexpensive nonmetallic, rigid microdialysis probe for use in electromagnetic radiation research or during magnetic resonance imaging. This probe has a concentric tube design, with the membrane length adjustable to the size of the area to be dialyzed. The probes tested had regenerated-cellulose membranes that were 3 mm in length. This report describes how to make this probe. Average relative recovery rates at flow rates of 2.0, 1.0, and 0.5 mu l/min were 21%, 27%, and 42%, respectively. These rates were slightly lower than the 30%, 42%, and 68% obtained with the commercially available metallic CMA10 microdialysis probe with a 3 mm membrane. This may be due to the fused-silica probe and CMA10 probe being made with different types of dialysis membranes. (C) 1995 Wiley-Liss, Inc. C1 OPERAT TECHNOL CORP,SAN ANTONIO,TX.

Cell transplantation using biodegradable polymer scaffolds offers the possibility to create completely natural new tissue and replace organ function. Tissue inducing biodegradable polymers can also be utilized to regenerate certain tissues and without the need for in vitro cell culture. Biocompatible, biodegradable polymers play an important role in organ regeneration as temporary substrates to transplanted cells which allow cell attachment, growth, and retention of differentiated function. Novel processing techniques have been developed to manufacture reproducibly scaffolds with high porosities for cell seeding and large surface areas for cell attachment. These scaffolds have been used to demonstrate the feasibility of regenerating several organs. C1 RICE UNIV,COX LAB BIOMED ENGN,DEPT CHEM ENGN,HOUSTON,TX 77251.

Unlike other working memory tasks that require a subject to perform for a reward such as food or water or to avoid shock, our task measured spontaneous exploration of novel and familiar objects and has been described as a ''pure'' working memory task [9]. Normal subjects spend significantly more time in contact with new environmental components and less time with familiar objects. A subject that extensively reexplores a stimulus with which it has previous experience is presumed to exhibit some memory loss associated with the object. Memory changes were evaluated by measuring the relative time subjects explored familiar versus new stimulus objects. Rats (n = 15) that chronically drank L-NAME (approximate to 90 mg/kg/day) for 14 days spent significantly less time exploring a novel object than did rats in = 13) that drank only tap water (p <.05). This effect of L-NAME was abolished by concurrent administration of L-Arginine (approximate to 4.5 g/kg/day). Total object exploration was not affected by our drug treatments, suggesting that our object discrimination task is not activity dependent. These data are consistent with the hypothesis that NO is required for some forms of working memory. C1 TRINITY UNIV, DEPT BIOL, SAN ANTONIO, TX 78212 USA.

All immunoassays performed equivalently for cocaine, opiates, and phencyclidine. All immunoassays detected the same amphetamine/methamphetamine-positive specimens, but all also detected numerous specimens containing cross-reacting sympathomimetic amines. CEDIA detected 100%, Emit II 93%, and RIA 82% of the barbiturate-positive specimens. Emit II and CEDIA detected 86-88% of the specimens found by RIA to be marijuana positive. A subset of specimens was additionally screened by Online (Roche) and TDx (Abbott) for amphetamines, cocaine, and marijuana. Online and TDx also detected all of the amphetamine-positive specimens and numerous specimens containing cross-reacting sympathomimetic amines. All immunoassays performed equivalently for cocaine, and the four nonisotopic tests detected 86-89% of the marijuana positives found by RIA. Interfering sympathomimetic amine drug compounds can be eliminated by using an oxidizing agent, thus decreasing the number of unconfirmable amphetamine presumptive positives. The CEDIAs for all of the major drugs of abuse are reliable and effective for large-volume urine screening programs.

When a high-Damkohler-number hydrogen flame is stretched, the flame temperature changes-not because of incomplete chemical reactions, but due to the preferential diffusion resulting from the nonunity Lewis number. These changes are examined using a Computational Fluid Dynamics with Chemical reactions (CFDC) code that is third-order accurate. Detailed chemical kinetic including NO reactions is used to investigate the effects of stretch on the flame structure. A low-speed H-2/air diffusion flame having a fuel-jet velocity of 3.26 m/s is subjected to stretch using two vortices-one located on the fuel side of the flame and the other on the air side. Both vortices create positive (stretch) and negative (compression) flame-stretch factors when interacting with the flame. The temperature of the positively stretched flamelet was found to decrease when the vortex is located on the air side and to increase when it is on the fuel side. Similarly, compression of the flamelet resulting from the air-side vortex increases the flame temperature, whereas fuel-side vortex decreases the flame temperature. Among the eleven species considered in this model, production of NO in the flame zone appears to be the most sensitive to flame stretching or compression. Concentration of NO is found to be maximum in the compresses flamelet formed during the outside vortex-flame interaction. Finally, comparison of the mean-NO-concentration profiles obtained by averaging over several cycles of outside vortex-flame interactions and the time-averaged measurements yielded favorable agreement.

It is important to make such comparisons for both the same local three-dimensional stretch rte, which is measured instantaneously at locations along the flame front, and the same heat loss, as characterized by the product temperature T-2. The fundamental experimental procedure consists of interacting a laminar, premixed flame with an impinging vortex ring of reactants. The OH flame chemistry was quantified using planar laser-induced fluorescence (PLIF) techniques, while the three-dimensional stretch rate measurements were made possible by the use of particle-imaging velocimetry (PIV) diagnostics on the repeatable, axisymmetric experiment. Whereas previous comparisons have been limited to steady counterflow flame experiments, the present study considers a flame which is unsteady, freely-propagating, curved, far from walls, and has realistic heat losses; thus, it contains the physical processes present in turbulent premixed flames. It was found that there are significant (25%) differences between measurements and steady counterflow flame computations of peak OH mole fractions and OH reaction zone widths. Even where the stretch rate was constant along the flame, the OH profiles showed variations, indicating that the OH profile is not a unique function of the instantaneous local stretch, but depends on the time history of the flowfield. Such history effects may be better modeled using unsteady counterflow flame simulations. Large differences (a factor of two on centerline) occur between the measured three-dimensional stretch rate for meaningful comparisons with models. Sensitivity analysis shows that heat losses must be realistically modeled, especially if flame extinction is to be simulated. The present type of comparison represents a first step in the assessment of flamelet models. C1 AERO PROP & POWER LAB,WRIGHT PATTERSON AFB,OH. LOCKHEED ENGN & SCI CO,HAMPTON,VA 23666.

The MMC used was SCS-6/Ti-beta 21-S with a quasi-isotropic lay-up. Two sizes of hole were used which provided hole diameter to specimen width ratio of 0.167 or 0.4. Two test temperatures were used: ambient and 650 degrees C. At both temperatures, the tested MMC showed a mild hole size effect or notch sensitivity. A systematic investigation of initiation and propagation of damage mechanisms including failure modes was also conducted. Finally, the results of this study were compared with the corresponding counterparts under monotonic tensile loading. C1 USAF,INST TECHNOL,DEPT AERONAUT & ASTRONAUT,WRIGHT PATTERSON AFB,OH 45433.

During thermal cycling, matrix cracks initiated at the composite surface and propagated into the composite normal to the fiber direction. However, near the stress-free edges of all specimens, a region void of cracks existed which extended an average of 5.4 fiber diameters into the width of the composite. This cracking pattern was attributed to the presence of a thermally induced cyclic tensile residual stress which dissipates to zero near the stress-free edge of the composite. The finite element method was employed to determine how the fiber-matrix interface shear resistance influences the development of these residual stresses. Using coulomb friction as a measure of shear resistance, the matrix residual stresses in the fiber direction had a peak value of 500 MPa. A frictional coefficient range of 0.18-0.22 was found to give between 95% and 99% of this peak value within 5.4 fiber diameters from the edge. Thermal cycling of the model between 150 and 815 degrees C provided evidence that the resultant cyclic stresses were tensile in nature and were suggested as the probable cause of the periodic surface cracks. The reduction in post-cycling transverse strength with increasing gage-section width indicated that the smaller-width specimens exhibited less damage per cross-sectional area than the wider specimens.

Many micromechanical models have been used to relate the effective properties of these materials to volume fraction distributions. Herein, several of these models are examined and subjected to simple tests in order to determine their validity over this wide range of application. The self-consistent method surfaces as an attractive method that provides good estimates at minimal effort with no empirical fitting parameters. Using this method, it is shown that certain assumed property distributions presented in the literature must be used with care as they are not physically realizable for certain material combinations.

An integral methodology used in this paper considered the evaluation of the heat transfer process, non-linear composite plate response, failure modes, and eigenvalues for natural frequency and buckling load. The heat transfer process was modelled by a modified Crank-Nicholson finite difference scheme, which includes the effects of surface ablation, degradation of thermophysical properties at elevated temperatures, and radiation and convection heat losses. The predicted burnout geometry configuration and temperature distribution were then used for the subsequent investigations of load-carrying capability, free vibration, and buckling of the laminates. It was shown that material removal due to ablation and mechanical property degradation at elevated temperatures could significantly reduce load-carrying capability and alter vibration and buckling characteristics of the laminated composites.

The damage mechanisms considered in this paper are matrix cracking, fiber/matrix interfacial debonding, interfacial slip and fiber failure. Crack density is determined analytically through the introduction of a 'critical matrix strain energy'. A priori knowledge of the composite's 'proportional limit' yields a complete closed-form stress/strain solution. The influence of the interfacial shear stress, the interfacial bond strength and the composite proportional limit on the progression of matrix cracking and interfacial debonding are reported. The unloading behavior, including stress/strain hysteresis, is also modeled in terms of interfacial frictional slip within debonded regions.

A similar evaluation was carried out on a Ti-6Al-4V/SiC single-ply composite to illustrate the applicability of these techniques to composites containing high fiber volume fractions.

A steady-state population of Sb was maintained at the AlGaAs growth surface by providing a continuous Sb-2 flux to compensate for loss due to thermal desorption. A significant improvement in the optical quality of AlGaAs layers was observed by photoluminescence. Sharper GaAs QW. PL lines also indicate smoother inverted (GaAs on AlGaAs) interfaces when the Sb surfactant is employed. These improvements may be attributed to a reduced incorporation of impurities and point defects, and/or improved surface diffusion kinetics during AlGaAs MBE.

Photoluminescence (PL), secondary ion mass spectroscopy (SIMS) acid Auger electron spectroscopy (AES) are used to monitor degradation following rapid thermal annealing (RTA) at, temperatures between 600 and 800 degrees C. Epilayer integrity is maintained in both the SAG and RG structures to 600 degrees C. Interfacial degradation following RTA at 700 degrees C is more severe for the SAG structure. After 800 degrees C RTA, the GaAs0.51Sb0.49 channel no longer exists in either sample due to Ga and Sb indiffusion, and In and Al outdiffusion to the sample surface. The SIMS and AES results correlate with the PL results and indicate rapid thermal processing temperature limits of 600 degrees C for the SAG HIGFET and 700 degrees C for the RG HIGFET.

The dramatic effects of the heterogeneous collisional interactions between the electronic/vibronic states of the gas mixture constituents on the dissociation, ionization, gas heating, discharge impedance and power loading are described and discussed. A template construct of a collisional model of molecular gas mixtures where the electron kinetics are obtained from the collisional Boltzmann transport equation, and the vibrational kinetics are governed by a system of vibrational master equations, is described in detail. Three test cases are discussed: (i) Ar- Cl-2, (ii) N-2 - O-2, and (iii) N-2 - H-2. The generic guidelines that are derived from the analysis of the above mixtures are that: (a) There is a strong coupling between the dissociation and the ionization balances in gas mixtures. It is cautioned that for most conditions, even in pure molecular gases, neither channel can be studied independently of the other. (b) In molecular gas mixtures, the heterogeneous collisional interactions between the metastable excited electronic states play important roles in determining the discharge characteristics. (c) The calculations assuming constant E/N and constant electron density in gas mixtures can lead to inconsistent and misleading conclusions on the throughput of these discharges.

At this time the Iowa plasma wave experiment measured chorus emissions in the region of one third of the local electron gyrofrequency, and the Lockheed IMS-LO electron instrument observed an apparent velocity dispersion event in electrons between 770eV and 20 keV, beginning at about 15:12 UT. We describe the particle correlation technique, briefly present this event, and then describe an approach to testing the hypothesis that wave-particle interactions were responsible for the large modulation seen in the particle correlator. Recent work on the statistical analysis of such data is presented. C1 UNIV SUSSEX, CTR SPACE SCI, ENGG, BRIGHTON BN1 9QH, E SUSSEX, ENGLAND. UCL, MULLARD SPACE SCI LAB, LONDON, ENGLAND.

Design: Randomized, controlled interventional study to compare early ligation with formalin infiltration of the ductus arteriosus. Setting: Animal care facility at a dedicated research foundation. Subjects: Eighteen premature baboons delivered by hysterotomy at 140 +/- 2 day gestation. Intervention: Nine premature baboons underwent formalin infiltration of the ductus arteriosus (group 1), and nine underwent ductal ligation (group 2). Surgical ligation or formalin infiltration was performed at 2 to 4 hrs of age. Animals were maintained on mechanical ventilation and ventilator parameters were adjusted to maintain Pao(2) and Paco(2) within the physiologic range. Main Outcome Measures: Left ventricular output indexed to body weight and vital organ perfusion were measured at 24 hrs of age by the radiolabeled microsphere method. Lung mechanics, including lung wet/dry weight ratio, total lung water, static compliance and functional residual capacity were measured immediately following euthanasia. Results: Total pulmonary blood flow was significantly lower (p = .0001) in group 2 (mean = 94 mL/min/kg), compared with group 1 (mean = 287 mL/min/kg). Systemic blood flow and effective pulmonary blood Bow were higher in group 1 (p = .07). No significant difference between groups in absolute organ blood flow was noted, although flow as a percent of left ventricular index was significantly higher in all organs except the kidney in group 2. There was no difference in arterial blood gas values, parameters of mechanical ventilation, percent lung water, or postmortem measurement of lung mechanics between groups. Conclusion: Early ductal ligation did not result in improved cardiac output, increased organ blood flow, or improved pulmonary function. We postulate that gradual constriction of the ductus arteriosus may play an important role in successful cardiovascular adaptation in the premature infant. While it is clear that premature infants with symptomatic patent ductus arteriosus often benefit from ductal closure, we question the practice of prophylactic early ductal closure.

RESEARCH DESIGN AND METHODS - Dates of admission, diagnosis of diabetes, age, and gender were collected for all 522,326 children, age 21 or younger, of active duty military personnel admitted to U.S. Army treatment facilities during fiscal years 1971-1991. Incidence rates were expressed as cases per 100,000 person-years. RESULTS - A total of 2,308 cases of diabetes were diagnosed in 14.3 million person-years of follow-up over the 21 years. The overall incidence rate of diabetes in this population is 16.2 (95% confidence interval 15.5-16.9). For 1987-1991, the age-specific rates were 8.1 (0-4 years), 15.9 (5-9 years), 25.6 (10-14 years), 23.9 (15-19 years), and 23.4 (20-21 years). CONCLUSIONS - The rates may be biased because of exclusion of people with diabetes from entering military service, and are limited by lack of age adjustment. The racial admixture of our study population does not match the U.S. population as a whole. C1 ARMSTRONG LAB,DIV EPIDEMIOL RES,BROOKS AFB,TX.

The index cohort comprises conceptions and children of veterans of Operation Ranch Hand, the unit responsible for aerial spraying of herbicides in Vietnam from 1962 to 1971. The comparison cohort comprises conceptions and children of Air Force veterans who served in Southeast Asia during the same period but who were not involved with spraying herbicides. We found no meaningful elevation in risk for spontaneous abortion or stillbirth. In analyses of birth defects, we found elevations in risk in some organ system categories, which, after review of the clinical descriptions, were found to be not biologically meaningful. There was an increase in nervous system defects in Ranch Hand children with increased paternal dioxin, but it was based on sparse data. We found no indication of increased birth defect severity, delays in development, or hyperkinetic syndrome with paternal dioxin.

The objective of this work was to determine smoke production from burning ACM. A commercial version of the UPITT II combustion toxicity method developed at the University of Pittsburgh, and refined through a US Army-funded basic research project, was used to establish controlled combustion conditions which were selected to evaluate real-world exposure scenarios. Production and yield of toxic species varied with the combustion conditions. Previous work with this method showed that the combustion conditions directly influenced the toxicity of the decomposition products from a variety of materials.

DGV is based on measuring the Doppler shift of single frequency laser light scattered from particles in the flow. DGV and other now visualization tools were used to investigate the vortical flow above a sharp leading edge delta wing with attached twin vertical tails. Measurements were also made with the tails removed for purposes of comparison. The results show a strong interaction of the leading edge vortices with the tails. The presence of the tails caused the vortex burst point to move substantially upstream of the tails' leading edges. C1 FIMD, Wright Lab, Expt Diagnost Res Branch, Wright Patterson AFB, OH 45433 USA.

This paper will focus on those structural variations to promote this class of materials amenable to the state-of-the-art sol-gel processing. Our research on these systems involves tailoring the structure for improved solubility properties, as well as functionalizing their backbone structure for co-reaction with tetraalkoxysilanes. A series of benzazole and benzobisazole polymers were prepared containing sulfo pendent groups. Organic ammonium salts of these polymers were found to exhibit excellent solubility in methanol. It was found that commercially available silane coupling agents containing trialkylamino and trialkoxysilyl functionality provided the required solubility in methanol leading to clear homogeneous gels.

These thermo-oxidative stable copolymers with the Tg of ca. 330 degrees C can be incorporated with alkoxysilane by the sol-gel method. Hydroxypolybenzoxazoles could be reacted with an isocynatosilane coupling agent and then hybrid consequently with silica. The resulting hybrid films containing one third of silica were transparent. The mechanical properties of the hybrid materials were highly dependent on the nature of the organic polymers. In general, the tensile modulus of the hybrid materials increased with addition of silica, but the elongation at break decreased at higher silica contents.

The current draw can be plotted against time, showing a characteristic trace for the test performed. Sensors in the ATS power supply can be used to monitor the current flow during test execution. Defective components can be classified using a Neural Network according to the pattern of variation from the ''trace'' of a good card. This can be performed as a background function, with the network gaining in accuracy over time. This paper discusses the Neural Network Routine for diagnosing circuit faults using monitored power supply current. C1 USAF,SA ALC,LDAE,WASHINGTON,DC 20330.

Most past studies have assumed that these two gratings were in phase with each other. In the present work we investigate the effects that arise when a phase shift is purposely introduced between the two gratings. We use a normal coupled-wave analysis to calculate the reflection coefficient as a function of the detuning away from the Bragg frequency when this grating phase difference is varied from 0 to 2pi. We find particular phase difference values for which essentially a single-line reflection coefficient results, which in turn should produce narrow-band, single-mode operation of any device utilizing this Bragg structure for distributed feedback purposes.

Given M frequencies f(m), and I separate frequency estimators with unambiguous bandwidths F-i, the ambiguity problem can be stated as solving for the f(m) given the estimator outputs, alpha(mi), (1 less than or equal to m less than or equal to M; 1 less than or equal to i less than or equal to I) where f(m) = alpha(mi) + KmiFi and K-mi is some integer. The proposed algorithm exhaustively resolves all possible alpha(mi) groupings into single frequency values using a noise insensitive technique that exchanges system bandwidth for noise protection. The correct multiple frequencies are then defined as the single frequencies that repeat a specified number of times. A complete analysis is included.

Performance evaluation is based on elemental filter selection and MMAE estimation error sizes and trend. The elemental filters are based on either first or second-order acceleration models. Improved filter selection is achieved by using acceleration models that separate the frequency content of acceleration power spectral densities into non-overlapping regions with second-order models versus the more traditional overlapping regions with first-order models. A revised tuning method is presented. The maximum a posteriori (MAP) versus the Bayesian MMAE is investigated. The calculation of the hypothesis probability calculation is altered to see how performance is affected. The impact of the ad hoc selection of a lower bound on the elemental filter probability calculation to prevent filter lockout is evaluated. Parameter space discretization is investigated.

The symmetric problem is considered and follows from an exact elasticity solution formulated by Gupta [1]. The equations are valid for the planar problem, where the interface is straight and also for an axisymmetric problem in the presence of an annular or penny-shaped crack. The equations may serve to establish a tentative criterion that defines the subsequent direction of a crack impinging on a bimaterial interface.

The new AEDC Hypervelocity Testing Complex consists of: 1. A large 84-mm (3.3-in.)-bore two-stage light-gas launcher, capable of launching models into the 930-ft-long Range G, either free-flight or with track guidance and model recovery. 2. A 63.5-mm (2.5-in.) two-stage light-gas launcher, with similar performance to the previous G launcher, capable of launching models into a dedicated Impact Range. 3. A high-performance free-piston shock tunnel which utilizes the 2.5-in. Impact Launcher as the driver. The two hypervelocity ranges (1 and 2) are described and examples of different testing diagnostics are given. These diagnostics cover the spectrum from launcher to a variety of impact events.

Several variations of the resulting hybrid SPH formulation are discussed and tested against the Riemann shock tube problem.

Two types of impact simulations were investigated: high-power pulsed laser and laser-launched micro-flyer plate. In the first case a laser was used to generate a high-pressure shock wave which propagated into the target by means of rapid ablation of the target surface. The second case used the same laser to accelerate micro-flyer plates at a target. The laser-ablation technique and the apparatus used to propel the micro-flyer plates were compatible with a space environmental chamber equipped with instrumentation capable of analyzing the vapor ejected from the sample. Data obtained from two separate damage effects were of interest in this study: the vapor blow-off produced by the impact and the mechanical damage to the target. The value of the data obtained from both simulation methods was evaluated in terms of likeness to actual space debris damage. Data for this work were obtained from polysulfone resin and a graphite polysulfone composite. Polysulfone was selected because it was flown on the Long Duration Exposure Facility (LDEF) satellite which spent several years in low earth orbit and experienced many space debris impacts. The chemistry of the vapor produced by the two simulation techniques was analyzed with a time of flight mass spectrometer (TOFMS) which measured changes in the vapor chemistry as a function of time after impact, obtained a velocity measurement of the vapor, and estimated surface temperature immediately after impact using dynamic gas equations. Samples of the vapor plume were also captured and examined by transmission electron microscopy (TEM). The mechanical damage effects caused by the simulation methods on a graphite polysulfone composite and a polysulfone resin were studied. Impact craters were examined under optical and scanning electron microscopes (SEM). Based on the two damage effect criteria the micro-flyer method proved to be a useful way to simulate hypervelocity impact of space debris. The laser-ablation method however, had shortcomings and required drastic compromises in the set criteria. C1 CALIF STATE UNIV NORTHRIDGE,DEPT CIVIL & IND ENGN & APPL MECH,NORTHRIDGE,CA 91330.

Nine tests were conducted at the Air Force Arnold Engineering Development Center (AEDC) S1 Range Facility on ice, rock, and iron target samples using a spherical 2.39 mm diameter aluminum impactor at impact velocities of from 7.6 to 8.4 km/sec. The test objectives were to collect target response phenomenology data on cratering, momentum deposition and enhancement, target fragmentation, and material response under hypervelocity impact loading conditions. A carefully designed ballistic pendulum was used to measure momentum deposition into the targets. Observations and measurements of the impacted samples provide important insights into the response of these materials to kinetic energy impacts, especially in regards to unexpectedly large measured values of momentum enhancement to some of the targets. Such information is required to allow us to successfully deflect or fragment comets or asteroids which might someday be detected on collision trajectories with Earth.

JIT programmes consist of a number of different elements including change-over reduction, kanban methods, and preventive maintenance programmes. Some researchers have proposed lists of elements they believe are critical to JIT success. However, there is a lack of consensus among researchers as to which items should be included in the list of critical elements. Reports research, consisting of a survey of manufacturers known to be active in JIT exploration, and an in-depth case study to improve the understanding of the critical components in JIT programmes. Results from the survey were compared with existing research to determine better the elements critical to JIT success. C1 USAF,INST TECHNOL,WRIGHT PATTERSON AFB,OH 45433.

The purpose of these predictive capabilities is to provide fundamental information on the molecular interactions in graphite intercalates for optimization of electrodes in rechargeable batteries. The graphite sheet system was modeled on a workstation using MOPAC 93 to observe possible structural changes in the graphite following an intercalation process as well as any molecular orbital interactions between the graphite and the cation. Initial modeling of the graphite sheets used lithium intercalated graphite (LIG) as a benchmark. The results indicate that a complex graphite system can be modeled simply and effectively using semiempirical methods for the study of the intercalation-deintercalation behavior of ions.

Surface pressure measurements confirmed that the pitching wing generated a rapidly evolving, three-dimensional unsteady surface pressure field. Using these data, both linear and nonlinear neural networks were developed. A novel quasilinear activation function enabled extraction of a linear equation system from the weight matrices of the linear network. This equation set was used to predict unsteady surface pressures and unsteady aerodynamic loads. Neural network predictions mere compared directly to measured surface pressures and aerodynamic loads. The neural network accurately predicted both temporal and spatial variations for the unsteady separated flowfield as well as for the aerodynamic loads. Consistent results were obtained using either the linear or nonlinear neural network. In addition, fluid mechanics modeled by the linear equation set were consistent with established vorticity dynamics principles.

The technique involves the formation of a composite material consisting of gelatin microspheres surrounded by a PLGA matrix. The gelatin microspheres are leached out leaving an open-cell foam with a pore size and morphology defined by the gelatin microspheres. The foam porosity can be controlled by altering the volume fraction of gelatin used to make the composite material. PLGA 50:50 was used as a model degradable polymer to establish the effect of porosity, pore size, and degradation on foam mechanical properties. The yield strengths and moduli in compression of PLGA 50:50 foams were found to decrease with increasing porosity according to power law relationships. These mechanical properties were however, largely unaffected by pore size. Foams with yield strengths up to 3.2 MPa were manufactured. From in vitro degradation studies we established that for PLGA 50:50 foams the mechanical properties declined in parallel with the decrease in molecular weight. Below a weight average molecular weight of 10 000 the foam had very little mechanical strength (0.02 MPa). These results indicate that PLGA 50:50 foams are not suitable for replacement of trabecular bone. However, the dependence of mechanical properties on porosity, pore size, and degree of degradation which we have determined will aid us in designing a biodegradable scaffold suitable for bone regeneration.

However, recent reports have demonstrated that the sensitivity of LPA assays may be as low as 27 to 54%. The purposes of the present study were to directly compare the abilities of four urine antigen assays to detect GBS antigen with clinical urine samples from neonates with GBS bacteremia and to evaluate the effect of the urine concentration on the sensitivities and specificities of these assays. Urine samples were collected serially from neonates with blood cultures positive for GBS or on admission from healthy full-term infants. One milliliter of urine was removed, and the remainder was concentrated to a volume of 1 ml. Unconcentrated samples were serially diluted with normal saline and were assayed to determine the highest dilution which would produce a positive test result. The Wellcogen, Bactigen, and Directigen LPA tests and ICON immunoassay were directly compared by using concentrated and unconcentrated urine specimens and urine specimens with known titers. A total of 94 urine specimens, including 61 concentrated and 75 unconcentrated specimens, from bacteremic infants were available for sensitivity testing, and 220 urine specimens from uninfected infants were available for specificity testing. There were significant differences in sensitivity among the four assays when they were performed on concentrated urine specimens, as follows: Directigen, 98%; Bactigen, 92%; ICON, 89%; Wellcogen, 68%. When the assays were performed on unconcentrated urine specimens, the Directigen (84%) and Bactigen (76%) assays were each significantly more sensitive than the ICON (59%) or Wellcogen (43%) assay, All four assays were significantly more sensitive in detecting GBS antigen in concentrated than in unconcentrated urine. The Directigen assay detected antigen in higher dilutions (geometric mean titer, 1:5) than the ICON (1:3), Bactigen (1:2), or Wellcogen (1:1) assay. The specificity was 99.5% for all four assays when concentrated urine was used and for the Bactigen, Directigen, and ICON assays when unconcentrated urine was used; the Wellcogen assay was 100% specific when unconcentrated urine was used. We conclude that there are significant differences in sensitivity but not specificity among the commercially available assays for the detection of GBS antigenuria when concentrated and unconcentrated urine specimens are tested. These differences in sensitivity may affect the abilities of clinicians to accurately diagnose GBS sepsis before culture results are available.

Recent work in our Laboratories indicates that the study of surfactant enhanced solvent blends may be very rewarding in this regard. In particular, N,N-dialkylamides and N-alkylpyrrolidinones, although they are not as effective as chlorinated solvents, can be more easily blended with water and common surfactants to produce very effective solvent and reaction systems for toxic oils and inorganics. These solvents are biodegradable and not extremely toxic. We have initiated a study of the appropriate physical properties of these blends in order to determine their efficacy as media for the dissolution and degradation of model compounds.

This project focuses on the appropriate applications of feedback in a CAI lesson which teaches knowledge bases and concepts. The student's learning style/characteristics are a factor in the process. The project follows a 4 x 2 design which includes a pretest, intervention, posttest, and delayed posttest model. The factors of the design are feedback (KCR, KCRI, KOR, KORI) and learner characteristics (field dependent, field independent). The learners, freshmen cadets at the USAF Academy, were assigned to treatment groups via stratified random sampling. Stratification was based on pretest scores of prior knowledge and learner characteristics. The results of the primary intervention, level of feedback, were statistically significant, favoring increasing levels of information feedback. This article also provides instructors, instructional designers and authors of computer-assisted instruction useful methodologies for implementing the results in instructional products.

To achieve this, three sets of fatigue tests were conducted: 1) in-phase TMF (IP-TMF), 2) out-of-phase TMF (OP-TMF), and 3) isothermal fatigue (IF). The fatigue response was dependent on the test condition and the maximum stress level during cycling. The IF, IP-TMF, and OP-TMF conditions yielded shortest fatigue life at higher, intermediate and lower stress levels, respectively. Examination of the failure mode through the variation of strain or modulus during cycling, and post-mortem microscopic evaluation revealed that it was dependent on the fatigue condition and applied stress level. Higher stresses, mostly with IP-TMF and IF conditions, produced a primarily fiber dominated failure. Lower stresses, mostly with the OP-TMF condition, produced a matrix dominated failure. Also, an empirical model based on the observed damage mechanisms was developed to represent the fatigue lives for the three conditions examined here.

Elevated-temperature crack growth mechanisms in this alloy, which involve fatigue, oxidation and creep, and the influence of frequency, temperature, and hold-time are discussed. These mechanisms are used to interpret the observations of TMF crack growth. The limitations of current crack growth rate models based on the linear-elastic fracture mechanics parameter, K, are addressed.

The time-weighted accumulation corresponds to convolution of the auroral electrojet indices with an exponential weighting function with an e-folding time of 9.4 hours. The weighted indices AE,, and AL,, have correlation coefficients against Dst ranging between 0.8 and 0.95 for 20 of the 21 storms. Correlation over the entire solar cycle 21 database is also strong but not as strong as for an individual storm. A set of simple Dst prediction functions provide a first approximation of the inferred dependence, but the specific functional relationship of Dst (AE,) or Dst (AL,) varies from one storm to the next in a systematic way. This variation reveals a missing parametric dependence in the transfer function. However, our results indicate that auroral electrojet indices are potentially useful for predicting storm time enhancements of ring current intensity with a few hours lead time.

X-ray diffraction and transmission electron microscopy (TEM) were used to characterize powders and thin films deposited on TEM grids. While the solid-state kinetics of formation of LaAl11O18 are known to be extremely sluggish, the yield of LaAl11O18 formed by the sol-gel route was much higher than that obtained by processing under similar conditions by solid-state reaction of elemental oxides. The development of a very fine grained microstructure at 1200-degrees-C and a coarser, much more mature microstructure at 1450-degrees-C, with strong texturing of the magnetoplumbite phase, was observed by TEM. Isolated grains of LaAlO3 were present in all powders and films. Trace impurities, introduced most likely as impurities in the initital alumina sol, appear to have segregated to both the grain boundaries and to the external surfaces of grains in as-prepared films.

To explore the content and construction of human explanations, detailed protocol analyses were performed on the explanations that subjects produced while learning about a fictional system. During the system learning phase of the experiment, subjects received a series of diagrams for a system and then explained how it worked. During the troubleshooting phase, in the absence of the diagrams, subjects explained relations between problematic symptoms and their faults. To examine the evolution of explanations with learning, subjects explained the same system diagrams and the same symptom-fault relations multiple times. Explanations varied considerably between system learning and troubleshooting, indicating that different goals produced different explanations. During system learning, subjects focused almost exclusively on functional explanations, exhibiting no trend toward deeper mechanistic explanations over time. To construct these functional understandings, subjects primarily instantiated existing knowledge in memory, specializing it to explain the purposes of individual components. During troubleshooting, subjects still focused on function but included a much wider variety of functional information in their explanations as well as higher proportions of topographical and mechanistic information. Rather than focusing on individual components, subjects focused on qualitative relations between components as they attempted to understand forward causal relations from faults to symptoms. Also, unlike system learning, explanations during troubleshooting evolved significantly over time, shifting from qualitative reasoning to reminding. The topography and coherence of the diagrams studied in system learning affected subjects' explanations substantially: During system learning, explanations were more efficient and mechanistic when topography and coherence were present than they were when they were absent. During troubleshooting, these factors led to faster understanding of symptom-fault relations, as well as to higher rates of remindings, perhaps through improved indexing.

The class of systems considered retains the basic structure of Hopfield type neural networks with the nonlinearities having infinite gain. For the present model, we establish qualitative results which enable us to generalize the solutions of discrete-time systems in the discontinuous surfaces and to characterize the set of system equilibrium points (distribution of equilibria in the state space and stability properties of the equilibrium points). In addition, we develop an efficient synthesis procedure utilizing the eigenstructure method for the present class of neural networks. The synthesized networks are capable of learning new patterns as well as forgetting learned patterns. The resulting neural networks can easily be implemented in digital hardware. Furthermore, when implemented by a serial processor, the present results offer extremely efficient means of simulating corresponding continuous-time neural networks (modelled by systems of ordinary differential equations). The applicability of the present results is demonstrated by means of several specific examples. C1 UNIV NOTRE DAME, DEPT ELECT ENGN, NOTRE DAME, IN 46556 USA.

This improvement is due to several complimentary improvements in virtual environment supporting technologies, such as user interface devices, user interface design, head-mounted displays, network communications standards, computing power, and object-oriented technology. The success of the distributed virtual environment approach has served to increase the rate of change of the supporting technologies that are used. This technological turmoil can make it extremely difficult to devise and refine software components in target applications when the applications must also incorporate supporting technological advances as they emerge. Because the application tools and supporting technologies are changing, system requirements are continually changing and new requirements are emerge. In the case when baseline system requirements are known, they typically will change to take advantage of improvements in technology. The more typical case is that requirements are generally unknown before the system is implemented, hence-there is no baseline. Changes to the system must then be made without disrupting progress on unaffected system components. To accommodate the instability of user requirements and the accelerating change of pace of the underlying technologies, we created a software architecture suitable for implementing and maintaining applications that are developed using a rapid prototyping approach. We describe the software architecture and the modified rapid prototyping approach we devised to support our work in distributed virtual environments. The architecture supports several applications, two of which we summarize, while it continues to undergo modification.

There is also an ongoing, intense scrutiny of past radiation-exposure experiments with all of its possible ethical violations. This paper is a modest attempt to familiarize the reader with some of the historical development of ethics in human-use research. Debate concerning the use of humans as subjects of medical and behavioral experimentation has a long and distinguished history going back at least 2,000 years. A short historical review reveals that ethical behavior exhibits a pendulum action between the extremes of protection of humans at all costs and the attainment of scientific knowledge at all costs. Only by knowing the historical foundation of ethics can one understand the current issues surrounding human experimentation.

The validity of the data generated by human research is a direct result of the application of these ethical guidelines. The risk/benefit ratio evaluation can terminate a project even before its initiation. New technology, individual beliefs, and a changing society will continue to guarantee controversy over how human subjects should be screened and evaluated as well as how research should utilize them. Ethical guidelines are not cast in stone. Their interpretation is influenced by new experimental results, the individual researcher, the intended subject, the composition of human use committees, and the social environment.

During a 3-year period, a total of 504 suspected child abuse patients were evaluated by our CAN team. After preliminary evaluation, 264 (52%) of these cases were unsubstantiated. Eighteen of these 264 (7%) were initially considered as cases of CAN but were later proven to be conditions that were misdiagnosed as CAN. Thirteen of the 18 (72%) were readily diagnosed after consultation with a pediatrician or other health care consultant. Investigation of the remaining 5 patients (29%) was more difficult and more extensive, requiring a period of separation from the parents with consequent emotional hardship to the family. These conditions included (1) a patient with osteogenesis imperfecta type IV, (2) a patient with Ehlers-Danlos syndrome, (3) two patients with benign external hydrocephaly of infancy, and (4) a patient with Crohn's disease, who was evaluated for sexual abuse because of chronic abdominal pain. A comprehensive literature review of pediatric conditions that may mimic CAN is presented by diagnostic categories to assist clinicians in differentiating medical conditions that may simulate CAN. Methods to support parents who have been incorrectly reported are discussed.

The literature is mute on this issue. The Working Group concluded that such operational exposures have been present only since the onset of high-G aircraft (F-15/F-16); human centrifuge experience indicates no pathology, although long-term follow-up has not been accomplished; and the index of suspicion of significant clinical pathology is low, based on historical considerations. Considerations for future studies of lifetime G effects include: a determination of what organs to study; the realization that animal studies are probably not valuable; the determination that prospective longitudinal studies are optimal but costly in time and funds; and the opinion that a properly conducted cross-sectional study based on past exposure may be feasible, acceptable, and less costly.

Semiconducting samples (x greater than or equal to 0.4), in which only 2D electrons exist in the InAs wells, exhibited cyclotron resonance (CR) splittings due to large nonparabolicity. Semimetallic samples (x = 0.2 and 0.1), in which both 2D electrons and 2D holes are present, showed a variety of absorption lines, including ''X-lines'' that we have ascribed to intra-exciton transitions and electron-CR with strongly oscillatory linewidth, amplitude, and mass, part of which are interpreted in light of peculiar ''anti-nonparabolic'' band structure resulting from band overlap and coupling between conduction-band states in InAs and valence-band states in AlGaSb.

This paper reviews concepts associated with the processing of military data to find and recognize targets-automatic target recognition (ATR). A general-purpose automatic target recognition system does not exist. The work presented here is demonstrated on military data, but it can only be considered proof of principle until systems are fielded and proven ''under-fire''. ATR data can be in the form of non-imaging one-dimensional sensor returns, such as ultra-high range-resolution radar returns for air-to-air automatic target recognition and vibration signatures from a laser radar for recognition of ground targets. The ATR data can be two-dimensional images. The most common ATR images are infrared but current systems must also deal with synthetic aperture radar images. Finally, the data can be three-dimensional, such as sequences of multiple exposures taken over time from a nonstationary world. Targets move, as do sensors, and that movement can be exploited by the ATR. Hyperspectral data, which are views of the same piece of the world looking at different spectral band, is another example of multiple image data; the third dimension is now wavelength and nor time. ATR system design usually consists of four stages. The first stage is to select the sensor or sensors to produce the target measurements. The next stage is the preprocessing of the data and the location of regions of interest within the data (segmentation). The human retina is a ruthless preprocessor. Physiology motivated preprocessing and segmentation is demonstrated along with supervised and unsupervised artificial neural segmentation techniques. The third design step is feature extraction and selection. the extraction of a set of numbers which characterize regions of the data. The last step is the processing of the features for decision making (classification). The area of classification is where most ATR related neural network research has been accomplished. The relation of neural classifiers to Bayesian techniques is emphasized along with the more recent use of feature sequences to enhance classification. The principal theme of this paper is that artificial neural networks have proven to be an interesting and useful alternate processing strategy. Artificial neural techniques, however, are not magical solutions with mystical abilities that work without good engineering. Good understanding of the capabilities and limitations of neural techniques is required to apply them productively to ATR problems.

A shared weight neural network is applied in correlation fashion to images of outdoor scenes. Two sets of images are considered. The first set consists of forward looking infrared images of tanks. The second set consists of visible images of cars in a parking lot. The goal in the first set of images is to detect the tanks. The goal in the second set of images is to detect the Chevrolet Blazers. The second problem is much more difficult than the first. The networks are compared to a minimum average correlation energy (MACE) matched filter approach. The shared weight network was found to be better at generalizing. Problems were found in trying to suppress spurious outputs on the background. As a result, an improved training algorithm was developed. C1 USAF,EGLIN AFB,FL 32542.

To investigate the psychologic responses of these groups to traumatic stress, we studied health care and rescue workers involved in the 1989 air show disaster at Ramstein Air Force Base, Germany. We review reports from descriptive questionnaire data. The reports identified two types of disaster experience that were prominent: exposure to the grotesque, and no participation in the disaster relief efforts. Responses to debriefing are examined. The reports identified three characteristic responses: identification, sense of helplessness and inadequacy, and psychologic distancing. Further empirical study of these areas is needed.

Participants were grouped-into three categories: forty-three who were seropositive for HIV (the HIV+ group), sixty-eight who were seronegative but who were involved as volunteers or professionals in AIDS hospices, wards or organizations (the AIDS-involved group), and fifty-five who had no direct involvement in AIDS other than their risk group membership (the uninvolved group). We found that 1) the HIV+ group reported greater fear of premature death, 2) the AIDS involved group demonstrated significantly lower levels of death concern than the other two groups, and 3) both the involved and HIV+ groups reported higher levels of religious belief than the uninvolved group of G/B men. Finally, intrinsic religious orientation was negatively related to both overall death threat as measured by the Threat Index and fears specific to the possibility of an afterlife, but not to other components of death concern as measured by the Multidimensional Fear of Death Scale.
