16 SS ON AN ACUTE HOSPITAL WARD WERE TESTED ON RECOGNITION OF STATEMENTS MADE DURING WARD COMMUNITY MEETINGS WHICH THEY HAD ATTENDED. STATEMENTS WERE CATEGORIZED ACCORDING TO THE HILL INTERACTION MATRIX, AND THE AVERAGE MEMORY SCORES FOR 5 OF THE HILL CATEGORIES WERE COMPARED. RESULTS INDICATE THAT STATEMENTS ABOUT WARD BUSINESS AND ABOUT BEHAVIOR OF SS DURING THE MEETING WERE BEST REMEMBERED, WHILE STATEMENTS ABOUT SS' LIVES INDEPENDENT OF OTHER MEMBERS OF THE GROUP AND GENERALIZATIONS ABOUT HOW PSYCHOTHERAPY WORKS WERE LESS WELL REMEMBERED.

Selected conditions were examined for their possible roles in the regulation of catalase activity in Staphylococcus aureus MF-31. The addition of the heme precursor 5-aminolevulinic acid resulted in increased catalase activity whereas the addition of exogenous hydrogen peroxide did not. Catalase activity decreased when S. aureus MF-31 cells were grown in media containing glucose. Cells grown in media with succinate or citrate substituted for glucose exhibited increased catalase activity. Cells grown in tryptic soy broth (0.5% NaCl) supplemented with NaCl showed increased catalase activity at salt concentrations up to 3%. 相似文献

2 GROUPS OF RETARDATES WERE MATCHED FOR INTELLECTUAL FUNCTIONING AND CA UPON INSTITUTIONALIZATION, DIAGNOSIS, AND SEX. 1 GROUP (I) WAS ENROLLED IN SPECIAL EDUCATION CLASSES; THE OTHER GROUP (II) WAS NOT. AFTER 4 YR. OF THESE RESPECTIVE TREATMENTS. GROUP I EVIDENCED SUPERIORITY OVER GROUP II IN ACQUISITION OF PERSONAL SKILLS (BEHAVIORS REFLECTING ABILITY TO ASSUME IN PERSONAL RESPONSIBILITY FOR ONE'S SELF AND ONE'S POSSESSIONS), BUT NO SUPERIORITY IN ACQUISITION OF SOCIAL AND EMOTIONAL BEHAVIORS (ABILITY TO RELATE TO OTHERS AS INDIVIDUALS AND IN GROUPS). IN EACH GROUP, MA RELATED TO THE ACQUISITION OF PERSONAL SKILLS, BUT NOT TO SOCIAL AND EMOTIONAL BEHAVIORS. THESE RESULTS ARE FELT TO HAVE IMPLICATIONS FOR THE ASSESSMENT AND TRAINING OF RETARDATES.

The high-low inversion in polycrystalline cristobalite, synthesized from quartz at 1500°C, was investigated by differential thermal analysis to 7 kbar in hydrostatic apparatus. A region of anomalous curvature ( d2 T/dp2 >0) exists to ∼1 kbar; at higher pressure, the low→high and high→low transition temperatures vary linearly with pressure, with slopes of ∼51.1 and 53. 6 deg kbar−1 , respectively. Extrapolated 1-bar intercepts are ∼232° and ∼209°C, respectively. It is concluded that high cristobalite is less compressible than low cristobalite near the inversion. The hysteresis between the high→low and low→high transition temperatures decreases with increasing pressure. 相似文献

Computer-modelling techniques are applied to the calculation of defect formation and migration energies in α-Fe2 O3 and α-Cr2 O3 : both electronic and lattice defects are considered. The results are used to predict Arrhenius energies for cation and anion migration in different composition and temperature regimes and show reasonable agreement with experimental data where these are available. 相似文献

The decomposition of boehmite, or alpha alumina monohydrate, was studied in water vapor and nitrogen atmospheres between 430° and 500°C. Powder samples used consisted of agglomerates of very small boehmite crystallites. The rate of decomposition was determined with a transducer which measured the loss of sample weight due to the liberation of gaseous water. A linear rate law is obeyed by the decomposition of boehmite and, because of the characteristics of the fractional weight loss-time curve, an interface model was suggested as the mechanism of decomposition. The activation energy was 70 kcal/mole. The effect of water vapor on the rate of decomposition was investigated. A simple forward-back reaction mechanism did not satisfactorily explain the data. Two models, either of which could be valid, were proposed to describe the relation between decomposition rate and water vapor pressure: (1) An adsorption-desorption process of water on the boehmite was assumed, and (2) an intermediate species of Al2 O3 entering into the decomposition reaction was assumed. 相似文献
