Towards an understanding of affirmative action (AA)
… society. Presently, the intervention strategy, AA, has become the order of the day. There exists major dissatisfaction and disillusion with the current AA processes. An understanding of the phenomenon AA would be useful in the consideration and successful implementation of future AA processes. …

Stress Relaxation of AA 5182 During Hot Deformation
… is to model the recovery in the aluminum alloy, AA 5182, at temperatures above one half the melting point. The project is motivated by the recovery of AA 5182 during the industrial process of hot tandem rolling. The rolling operations typically take place at temperatures between 300°C and 500°C …

Asymmetrische Dihydroxylierung (AD) und asymmetrische Aminohydroxylierung (AA) mit immobilisierten Alkaloiden
… (AD) and Asymmetric Aminohydroxylation (AA) of olefins introduced by Sharpless represent efficient methods for the preparation of diols respectively vicinal aminoalcohols. Within this thesis the attachment of different ligand types (pyrimidine-, diphenylpyrazinopyridazine- and …

Structure-Function Relationship Studies of the Rhodobacter Sphaeroides Cytochrome AA(3)
Cytochrome c oxidases catalyze the reduction of O2 to H 2O and use the redox energy released by this reaction to generate an electrochemical proton gradient. This proton gradient can be used to produce ATP by ATP-Synthase. Rhodobacter sphaeroides cytochrome c oxidase, the focus of this thesis, …

Investigation of Adiposity Phenotypes in AA Associated With GALNT10 & Related Pathway Genes
… association studies in African Americans (AA) have identified common variants upstream of GALNT10 locus for association with body mass index (BMI). These studies encompassed a small number of variants upstream of GALNT10 that were common, noncoding variants, as is typically seen in GWAS …

DEPDC5 is a metabolic checkpoint regulator in the B cell AA-mTORC1 pathway
… metabolic programs. In recent years amino acid (AA) sensing and availability have been shown to be important for the control of mTORC1 in various cell types, however their importance in B cell metabolism was largely unknown. DEPDC5 is a metabolic checkpoint protein that mediates crosstalk between …

Studies on the Proton Pumping Mechanism of Aa(3)-Type Cytochrome C Oxidase
The monomeric form of bovine heart mitochondrial cytochrome c oxidase was used to detect directly the proton uptake and release events during the F-to-O transition. Absorption change of the pH sensitive dye was monitored spectroscopically. Rapid proton release followed by slow proton uptake was …

Computer Assisted Instruction in Class a and Class Aa Elementary Music Classrooms in Southwest Missouri
… music instructors of class A and class AA schools in Southwest Missouri. The results of the questionnaire showed that only one instructor uses Computer Assisted Instruction in their music classroom. Other instructors gave such reasons as poor access to a computer, lack of materials for …

Role of IGF-II, PRL, and FABPs in the Breast Cancer Disparity among AA Women
It is well documented that African-American (AA) patients present with more advanced states of breast cancer and have lower survival rates than Caucasian-Americans (CA). Epidemiological data have shown that pregnancy and lactation at an early age in humans reduce the risk of breast cancer. Studies …

Cytochrome AA(3) From Rhodobacter Sphaeroides: Affinity Purification and Biophysical Characterization of Site-Directed Mutants
Cytochrome c oxidase of R. sphaeroides has been purified using affinity methods and studied using site-directed mutagenesis coupled with a wide variety of biophysical characterization methods. Two methods of affinity purification were developed. Site-directed mutants were constructed in regions of …

Quantification of fatty acids over the gametogenic cycle of striped bass (Morone saxatilis) with varying dietary levels of DHA, EPA and AA
… acid (EPA) and arachidonic acid (AA) were increased in a stepwise fashion progressing from diets 1-4 respectively. A significant difference was seen in the tissues between fish from dietary treatment group 1 when compared to those fish from dietary treatment group 4 suggesting a …
