The Teratogenic Effects of Nocodazole and Acrylamide in Mus Musculus

Description: In two separate experiments, weight adjusted doses of nocodazole and acrylamide were injected intraperitoneally at various time intervals into twelve week old female mice. Within the nocodazole experiment, the doses were injected at varying time intervals before and after mating. On day seventeen of gestation, the female mice were sacrificed and their uterine contents examined. Nocodazole induced a significant increase in reproductive pathology per total implants when administered one hour aft… more

Biological Control of the Red Imported Fire Ant by the Entomopathogenic Nematode, Steinernema Carpocapsae (Weiser)

Description: Field trials were conducted in 1988 to evaluate the effectiveness of Steinernema (=Neoaplectana) carpocapsae (Weiser) in controlling the fire ant. Infective juveniles (IJ) of the nematode were applied as drench on 235 and 422 mounds, respectively for 2-month summer and 6-week fall evaluation periods. In comparative trials, amidinohydrazone (Amdro) was applied to 249 (summer) and 65 (fall) active mounds, with 245 (summer) and 78 (fall) untreated active as controls. Nematode treatments resulted i… more

A Study on the Successful Self-Employed in Malaysia

Description: In a dualistic labor market, self-employment is classified as the informal sector because its members are usually unable to find formal jobs.

This thesis studies the factors that can explain the successes of these self-employed such as the extent of their capital, entrepreneurial exp… more

Between the First World War and the Hutchins Commission report of 1947, Walter Lippmann and other media critics theorized that journalistic objectivity is impossible, but recognized journalists' responsibility to interpret events to their publics. In the 1930s these new theories coincided with historical events to encourage journal… more

Characterization of the Outer Membrane of Treponema Pallidum Subsp. Pallidum by Binding Studies Using Antibodies, Complement, and Host Serum Proteins

Description: The major goal of this study was to achieve sustained cultivation of virulent T. pallidum in vitro. The putatuive binding of host proteins to the outer membrane (OM) of intact, virulent T. pallidum subsp. pallidum has been investigated. A major breakthrough was the development of a filtration assay, usinglow protein-binding membrane filters, for the measurement of substances bound to or incorporated into th eOM of T. pallidum. This avoided the conventional manipulations which can damage the fra… more

Characterization of Human Glucose-6-Phosphate Isomerase of Different Sizes

Description: Glucose phosphate isomerase (GPI) was purified from human placenta utilizing cross-linked spherical particle phosphocellulose. In three steps, GPI could be purified approximately 5500 fold with greater than 50% recovery. The purified enzyme exhibited four bands upon non-denaturing PAGE and isoelectric focusing (IEF) when stained with GPI specific activity stain. The four isozymes were isolated by preparative IEF. The isoelectric points of the isozymes were determined. Sodium dodecyl sulfate (SD… more
