“I've Got Some Bad News…”:Veterinarians' Recollections of Communicating Bad News to Clients1

The purpose of this investigation was to gain a better understanding of the transactional processes associated with communicating bad news. The authors asked 62 veterinarians to recall a time when they gave bad news and to respond to a series of statements designed to assess what they did in the transaction and how the transaction impacted the receiver of the news, as well as themselves. The majority of participants followed recommendations published in the medical and veterinary literatures, but rated some of these recommended strategies as making the news harder to give. Although these transactions were not rated as being overly stressful, for some veterinarians stress transcended the bounds of the interaction. Consistent with a transactional stress and coping perspective, preparation efforts were correlated with delivery efforts. However, preparation stress was unrelated to preparation or delivery efforts, and neither preparation efforts nor delivery efforts related to effectiveness appraisals or perceptions of client satisfaction.

Rapid and sensitive gas chromatographic determination of estazolam

Abstract The triazolobenzodiazepine estazolam can be quantitated by gas chromatography with electron-capture detection. After addition of a suitable internal standard, plasma samples are extracted into toluene—isoamyl alcohol or benzene—isoamyl alcohol. The organic extract is separated, evaporated to dryness, reconstituted, and chromatographed using a 50:50 methyl—phenyl column (SP-2250). The sensitivity limit is approximately 1 ng of estazolam in a 1-ml sample. The method is suitable for clinical or experimental pharmacokinetic studies.
Chest radiograph interpretation of Pneumocystis carinii pneumonia, bacterial pneumonia, and pulmonary tuberculosis in HIV-positive patients : Accuracy, distinguishing features, and mimics

The purpose of this study was to assess the accuracy of chest x-ray (CXR) interpretation in the diagnosis of pneumocystis carinii pneumonia (PCP), bacterial pneumonia (BP), and pulmonary tuberculosis (TB) in human immunodeficiency virus (HIV)-positive patients and to identify the frequency with which these infections mimic one another radiographically. The admitting CXRs of 153 HIV-positive patients with laboratory proven BP (n = 71), PCP (n = 73), and TB (n = 9) and those of 10 HIV-positive patients with no active disease were reviewed retrospectively and independently by three radiologists who were blinded to clinical and laboratory data. Median percent accuracies were as follows: TB, 84%; PCP, 75%; BP, 64%; and no active disease, 100%. Fifteen of 153 cases (9.8%) were shown to mimic other infections radiographically. A confident and accurate diagnosis can be made radiographically in the majority of cases of PCP, BP, and TB in HIV-positive patients at the time of hospitalization. In approximately 10% of cases, these infections may mimic one another radiographically.
Debye screening and the Meissner effect in a two-flavor color superconductor

I compute the gluon self-energy in a color superconductor with two flavors of massless quarks, where condensation of Cooper pairs breaks SU(3){sub c} to SU(2){sub c}. At zero temperature, there is neither Debye screening nor a Meissner effect for the three gluons of the unbroken SU(2){sub c} subgroup. The remaining five gluons attain an electric as well as a magnetic mass. For temperatures approaching the critical temperature for the onset of color superconductivity, or for gluon momenta much larger than the color-superconducting gap, the self-energy assumes the form given by the standard hard-dense loop approximation. The gluon self-energy determines the coefficient of the kinetic term in the effective low-energy theory for the condensate fields. (c) 2000 The American Physical Society.

L'art et l'inceste : Sarabande d'Ingmar Bergman

Resume Le dernier film de Bergman, Sarabande, permet de degager une problematique, l'inceste pere–fille, qui est presente a travers toute la longue carriere du cineaste sans avoir ete resolue. La confrontation du texte de cet ultime scenario d'un des auteurs majeurs du XX e siecle, avec la prime de signification apportee ensuite par sa mise en images, permet de decouvrir des elements de la structure familiale et en particulier, celle du pere pervers, qu'il est difficile d'elucider dans la clinique. Cette etude compare les ecrits de Bergman, autant les textes autobiographiques, que litteraires, aux travaux sur la theorie psychanalytique et des cas cliniques. Le but de cette etude est de contribuer a une meilleure comprehension de l'inceste dans le cadre de la perversion. Bergman nous suggere aussi que l'echec du lien parent–enfant pourrait avoir des consequences desastreuses pour l'enfant, de l'ordre de l'autisme, aussi bien que pour le parent, l'angoisse. Le deficit dans la mise en place de l'image de soi se revele etre determinant dans le rapport a la Loi de la structure perverse.
Static and dynamic light scattering of a random coil polymer in rodlike polymer solution

We have studied ternary solutions of rodlike and random coil polymers in a common solvent. In these solutions, the rods scatter weakly, and almost all scattering comes from the coil component. From light scattering measurements, we gained information about the thermodynamic and hydrodynamic properties of the coil in rodlike polymer solutions.
Numerical Simulation of MSE Wall Behavior Induced by Surface-Water Infiltration

AbstractA series of numerical simulations, including transient seepage analyses and stress deformation analyses, was performed to predict the behavior of a mechanically stabilized earth (MSE) wall subjected to surface-water infiltration. In this research, two mechanisms to cause the deformation because of wetting were considered: (1) the deformation induced by shear strength decreases and (2) the volumetric deformation (swell or collapse) because of wetting. The effects of low as-compacted water content and a low-quality compaction zone behind the wall face on the wall behavior were investigated. As result of the simulations, the wall deformations (face deflections and reinforced-soil settlements) and reinforcement tensions (maximum tensions) are presented at the end of construction and after periods of surface-water infiltration.
The soil microbial community in a sewage-sludge-amended semi-arid grassland

The value of sewage sludge for improving the fertility and productivity of a degraded semi-arid grassland soil was tested by quantifying and describing the effects of surface application of sewage sludge on soil chemical properties and the soil microbial community. Three surface application rates (22.5, 45, and 90 Mg sludge ha−1) were tested over the course of two growing seasons. Most nutrient levels, including N, P, and K, increased linearly with increasing sludge application rates. Soil pH, however, declined linearly, from 7.8 to 7.4, with increasing sludge application rates. With the exception of Zn, heavy metals, including Cd, did not increase with the small decrease in pH or with increasing sludge application rates. Soil bacterial, fungal, and ammonium oxidizer populations increased linearly with increasing sludge application rates, and Streptomyces spp. populations remained relatively unchanged. The diversity of fungal groups declined initially with increasing sewage sludge rates but rebounded to near pretreatment levels under the low and intermediate application rates within 1 year. High fungal populations and low fungal diversity were related to the high nutrient contents provided by sludge amendment. Mucor spp. and Penicillium chrysogenum dominated the sludge-amended soils, and their densities in the treated soils in the first growing season were almost directly proportional to the sludge application rates. The improvement in soil fertility of a degraded semi-arid grassland due to sludge application was reflected in populations, diversity, and composition of the soil microbial community.
Potential Aggregation-Prone Regions in Complementarity-Determining Regions of Antibodies and Their Contribution Towards Antigen Recognition: A Computational Analysis

Computer architectures for logic-oriented data/knowledge bases

Knowledge base management systems (KBMS) are designed to efficiently retrieve and manipulate large shared knowledge bases. A significant subclass of KBMS consisting of a combination of logic programming and database is often called a logic oriented knowledge base system (LOKBS). These systems must possess considerable processing and I/O capabilities so many approaches have been taken to the improvement of their performance. In this paper we review the current performance enhancing hardware approaches for LOKBS. We include parallelism, both in processing and I/O, algorithms, caching, and physical data organizations.
V: Directions for Further Research

Research currently in progress with an MMPI-based taxonomy of youthful offenders is described and directions future research should take are indicated. Further research delineating the types, determining their response to different programs, and the stability of group membership over time are needed, as are studies exploring the applicability of the system to other groups of offenders. However, experiments comparing the groups' responses to different treatment programs pose serious methodological and ethical problems.
Bernstein Theorems for Elliptic Equations

We study solutions of the equation L(D) u = 0, where L(D) is an elliptic linear partial differential operator with constant coefficients and only highest order terms. For compact sets K ? RN with connected complement we prove a Bernstein theorem: if a function ? on K can be extended to a solution of the equation on an open neighborhood of K, then the supnorm distance from ? to the polynomial solutions of degree ? n decays exponentially with n. We give two proofs: a proof by duality which makes use of the theory of functions of several complex variables, and an elementary constructive proof using generalized Laurent expansions for solutions of elliptic equations. Finally, we discuss the use of orthogonal polynomial expansions, and the use of interpolation schemes, for the construction of polynomial approximations with asymptotically optimal behavior.
Bacteriophage N4-induced transcribing activities in E. coli. III. A thirdcistron required for N4 RNA polymerase II activity

The requirement of a third gene product of molecular weight 15,000 for coliphage N4 middle RNA synthesis is described. Therefore, three proteins of molecular weights 15,000, 30,000, and 40,000, which constitute the N4 RNA polymerase II activity, are required for N4 middle RNA synthesis. A complementation assay for N4 RNA polymerase II activity, which requires a DNA-membrane complex carrying the 15,000-MW protein and a supernatant providing the 30,000- and 40,000-MW proteins, has been developed. This assay, which reproduces the requirement for the cistron 5 gene product in vitro provides a means for the purification of the soluble components of the N4 RNA polymerase II activity (to be reported elsewhere). The cistron 5 gene product is also required for N4 RNA polymerase II to synthesize RNAs utilizing middle promoters resident in recombinant plasmids. Mechanisms by which the cistron 5 gene product affects N4 RNA polymerase II transcription in vivo and in vitro are discussed.
Influence of dietary sulfur-containing amino acids on the bioavailability to rats of zinc in corn kernels

Abstract A whole-body radioassay method was used to assess effects of supplemental dietary amino acids on absorption by rats of zinc in two varieties of corn kernels labeled either intrinsically or extrinsically with 65 Zn. Corn genotypes were a normal type (Nor-corn) with one row of cells in the aleurone layer of the kernel and a variety (Mal-corn) that had multiple rows of cells in the aleurone. In experiment 1, rats fed a basal diet containing 15% soy protein absorbed 64% of the 65 Zn provided extrinsically in test meals. When provided test meals that contained intrinsically labeled Nor-corn or Mal-corn kernels, the rats absorbed 64 and 57% of the intrinsic 65 Zn, respectively. In rats fed diets that contained supplemental lysine, methionine, or both lysine and methionine, absorption of extrinsic 65 Zn averaged 69, 82 and 86% of the dose, respectively. In experiment 2, rats fed the basal diet absorbed 57 and 53% of the intrinsic 65 Zn in Nor-corn and Mal-corn kernels, respectively, but rats fed supplemental methionine or cysteine absorbed 73% of the intrinsic 65 Zn in either the Nor-corn or Mal-corn kernels. Supplemental methionine or cysteine fed to rats that were marginally zinc deficient enhanced the absorption of 65 Zn provided in test meals in the form of either intrinsically labeled corn kernels or as 65 Zn-labeled zinc sulfate.
Periodic mass extinctions and the Sun's oscillation about the galactic plane

Raup and Sepkoski1 have recently reported evidence fora 26-Myr periodicity in the occurrence of mass extinctions based on a study of marine fossils. The data baseline of 250 Myr suggests events of variable amplitude, with some of the strongest peaks associated with boundaries between major geological periods which have been defined by previous palaeontological studies. In a more limited quantitative study, Fischer and Arthur2 earlier cited evidence for a 32-Myr period of major extinction events. Hatfield and Camp3 were among the first to suggest that mass extinctions might be correlated with periodic galactic phenomena, noting intervals of 80–90 Myr between major mass extinctions with an exceptionally strong mass extinction every 225–275 Myr. Here we point out a possible correlation between the 26-Myr extinction period and the Sun's oscillation about the galactic plane.
