Description: The purpose of this thesis, "A Study of the Problem of Negro Crime in the United States," is to determine whether or not Negro crime increased during the period from slavery to 1945; and if so, what factors were responsible for this increase.

Description: Methanococcus jannaschii is a thermophilic methane producing archaebacterium. In this organism genes encoding the aspartate transcarbamoylase (ATCase) catalytic (PyrB) and regulatory (PyrI) polypeptides were found. Unlike Escherichia coli where the above genes are expressed from a biscistronic operon the two genes in M. jannaschii are separated by 200-kb stretch of genome. Previous researchers have not been able to show regulation of the M. jannaschii enzyme by the nucleotide effectors ATP, CTP and UTP. In this research project we have genetically manipulated the M. jannaschii pyrI gene and have been able to assemble a 310 kDa E. coli like enzyme. By using the second methionine in the sequence we have shown that the enzyme from this organism can assemble into a 310 kDa enzyme and that this enzyme is activated by ATP, CTP and inhibited by UTP. Thus strongly suggesting that the second methionine is the real start of the gene. The regulation of the biosynthetic pathway in Pseudomoans aeruginosa has previously been impossible to study due to the lack of CTP synthase (pyrG) mutants. By incorporating a functional uridine (cytidine) kinase gene from E. coli it has been possible to isolate a pyrG mutant. In this novel mutant we have ...

Description: This study used achievement and the ability to learn to measure the success of two teaching methods. One method focused on factual information alone and the other related material to specific subjects. of the ratio of achievement of factual material to the ability to learn of intermediate children when taught the separate subjects as compared with those taught in correlated core area fields.

Description: Because of the structural analogies between these compounds and several other physiologically active compounds, such as chloroamphenicol, 4,4'-diaminodiphenyl sulfone, and 2,2-bis-(p-aminophenyl)-1,1,1-trichloroethane, a more complete study of the reduction products and the sequence of catalytic reduction of N-(4-nitrophenacyl)-4-(1-hexyl)pyridinium bromide was made in this investigation.

Description: It is the purpose of this investigation to determine within the limitations of the study the relationship in the classroom between social class status as measured by an accepted instrument and social acceptance as measured by a sociometric test.
