A Behavioral Modification Analysis of the Effects of Multimedia First Aid Training on Injuries in an Industrial Setting

A Behavioral Modification Analysis of the Effects of Multimedia First Aid Training on Injuries in an Industrial Setting

Date: May 1987
Creator: Sturrock, James Lee
Description: Past research has shown a correlation between first-aid training and the reduction of injuries. This connection has been noted in off-the-job situations in addition to industrial studies. This project is an extension of those past findings with three notable differences: total population training was studied, as the intervention instead of just saturation treatment; attention was given to the effect that the half-life of training had upon injury reduction; and three randomly chosen small groups we're studied to determine short range effects. The theoretical bases from which the study hypothesis was developed originated in the Behavioral Science and Psychology literature. Discussions are developed around the mental structuring of accidental potential situations in the case of a person trained in first-aid principles. Behavior Modification was one of the principles of change that offered a.safer environment through first-aid training. Group contagion provided the setting for development of a safer place to work because of socialization to a "safe attitude." The intervention, American National Red Cross Standard Multimedia First-Aid Course, provided some of the mental developments toward modification of behavior. These were the modeling and rehearsal features of the course. A connection between group deviance and accident "proneness" led to a proposal that avoidance ...

Syntheses of Highly Strained Energetic Molecules and Development of New Synthetic Methodology

Syntheses of Highly Strained Energetic Molecules and Development of New Synthetic Methodology

Date: May 1987
Creator: Wu, An-hsiang
Description: The objective of this study was to synthesize new energetic, strained, saturated polycyclic compounds. For this purpose, new methodology has been developed, as follows: (i) Ketenes have been generated in situ via treatment of aldo-, keto- or alkenoic acid with either toluenesulfonyl chloride or 2-chloro-1-methylpyridfniurn iodide (Mulkaiyama's reagent). The reactive intermediates thereby generated have been found to undergo intramolecular [2+2] cycloaddition reactions in these systems.

Studies of Enzyme Mechanism Using Isotopic Probes

Studies of Enzyme Mechanism Using Isotopic Probes

Date: August 1987
Creator: Chen, Cheau-Yun
Description: The isotope partitioning studies of the Ascaris suum NAD-malic enzyme reaction were examined with five transitory complexes including E:NAD, E:NAD:Mg, E:malate, E:Mg:malate, and E:NAD:malate. Three productive complexes, E:NAD, E:NAD:Mg, and E:Mg:malate, were obtained, suggesting a steady-state random mechanism. Data for trapping with E:14C-NAD indicate a rapid equilibrium addition of Mg2+ prior to the addition of malate. Trapping with 14C-malate could only be obtained from the E:Mg2+:14C-malate complex, while no trapping from E:14C-malate was obtained under feasible experimental conditions. Most likely, E:malate is non-productive, as has been suggested from the kinetic analysis. The experiment with E:NAD:malate could not be carried out due to the turnover of trace amounts of malate dehydrogenase in the pulse solution. The equations for the isotope partitioning studies varying two substrates in the chase solution in an ordered terreactant reaction were derived, allowing a determination of the relative rates of substrate dissociation to the catalytic reaction for each of the productive transitory complexes. NAD and malate are released from the central complex at an identical rate, equal to the catalytic rate.

Physical, Chemical and Catalytic Properties of the Isozymes of Bovine Glucose Phosphate Isomerase

Physical, Chemical and Catalytic Properties of the Isozymes of Bovine Glucose Phosphate Isomerase

Date: August 1987
Creator: Cini, John Kenneth
Description: Glucose phosphate isomerase (GPI) occurs in different bovine tissues as multiple, catalytically active isozymes which can be resolved by polyacrylamide gel electrophoresis and isoelectric focusing. GPI from bovine heart was purified to homogeneity and each of the isozymes was resolved. Four of the five isozymes were characterized with regard to their physical, chemical and catalytic properties in order to establish their possible physiological significance and to ascertain their molecular basis. The isozymes exhibited identical native (118 Kd) and subunit (59 Kd) molecular weights but had different apparent pi values of 7.2, 7.0, 6.8 and 6.6. Structural analyses showed that the amino terminus was blocked and the carboxyl terminal sequence was -Glu-Ala-Ser-Gly for all four isozymes. The most basic isozyme was more stable than the more acidic isozymes (lower pi values) at pH extremes, at high ionic strength, in the presence of denaturants or upon exposure to proteases. Kinetic constants, such as turnover number, Km and Ki values, were identical for all isozymes. Identical amino acid composition and peptide mapping by chemical cleavage at methionine and cysteine residues of the isozymes suggest a postsynthetic modification rather then a genetic origin for the in vivo isozymes. When the most basic isozyme was ...
