Genetic Relationships Among Subspecies Of Vigna Unguiculata (L.) Walp. Based On Allozyme Variation, R. S. Pasquet

All Peer-Reviewed Publications

The cowpea [Vigna unguiculata (L.) Walp.] is a morphologically and genetically variable species composed of wild perennial, wild annual, and cultivated forms that are mainly used for edible seeds and pods. In this study, genetic variation in 199 germplasm accessions of wild and cultivated cowpea was evaluated using an allozyme analysis. The results from this survey showed that wild cowpea exhibits genetic variation perfectly fitted with the existing morphological classification. The cowpea gene-pool is characterized by its unusually large size. It encompasses taxa (ranked as subspecies) that could be considered as different species considering the high genetic distances observed between …

Development Of Odour-Baited Traps For Glossina Swynnertoni (Diptera: Glossinidae), P. N. Ndegwa, S. Mihok

All Peer-Reviewed Publications

Three new prototype traps, (S1-S3), were developed during studies of the behavioural ecology of Glossina swynnertoni Austen in Kenya and Tanzania. The traps were compared in latin square experiments relative to the regular biconical trap as a standard and a selection of other conventional tsetse traps. Observations were also made on fly behaviour in the vicinity of traps using electric nets and sticky materials. When baited with acetone and 1-octen-3-ol, the S1 trap was 3.5 times as effective in catching G. swynnertoni in Kenya as the biconical trap. In Tanzania, the relative performance of the S1 and biconical traps differed; …

Vitamin Effect On The Aerobic Biodegradation Of Phenanthrene, Antracene, Fluoranthene, And Pyrene In A Contaminated Soil From An Industrial Site, Ilkay Cam

Theses

Bioremediation of organic wastes is often a cost-effective technology for the in situ treatment of contaminated soils. In this study, the possibility of increasing the rate and extent of biodegradation for phenathrene, anthracene, fluoranthene, and pyrene in an industrial PAH contaminated soil via vitamin mixture supplementation was explored.

Soil contained with PAHs was obtainecl from the Bayway refinery site formerly owned by Exxon (Linden, NJ). Experiments were conducted in which the contaminated soil was amended with a mixtures of four vitamins (niacin, biotin, folic acid, and panthothenic acid). Peat moss, a common soil amendment, was also added in some experiments. …

Vital Communities Criteria For Urban Neighborhood Development, Peter Frederick Smith

Theses

It is the goal of this document to explore the issues and physical attributes related to the creation of vital communities. Research into North American and European precedents of planned community design, from the late 19th Century to the present, and the study of the qualities of vitality of two healthy neighborhoods; The Beaches in Toronto, Canada, and the Ironbound in Newark, New Jersey, have demonstrated that the model for neighborhood development is the main street.

Further research determined that Springfield Avenue, in the City of Newark, New Jersey, would provide the armature for the revitalization of an urban neighborhood, …
