Self-Starvation Of Rats In Running Wheels As A Function Of Activity-Food Interval And Food Consistency, Ingrid Kalwas Stephens

Psychology Theses & Dissertations

Rats under restricted food schedules are generally capable of maintaining stable body weights by reducing energy output. However, if they are given access to running wheels, they fail to respond with this adaptive strategy. Instead, they show an increase in activity and a paradoxical decrease in caloric intake, leading to the development of stomach ulcers and death. Since food-yoked controls kept in standard cages remain ulcer-free and survive, the formation of stomach lesions appears to be due to the combination of increased energy expenditure and insufficient food intake. The present study attempted to attenuate this self-starvation effect by providing more …

Four additional onshore-offshore hydrographic sections were completed north and south of the main section. Temperature, salinity, dissolved oxygen, and nutrient (N0₃, PO₄, and Si0₂) data were collected.

Two spin off eddies were observed at the Gulf Stream front at the shelfbreak. These eddies resulted in the upwelling of nutrient-enriched North Atlantic Central Water. A period of downwelling was observed between the two upwelling events. The cycling between upwelling and downwelling was relatively rapid. …

Civil Pageantry In The Reigns Of Elizabeth I And James I Of England, 1558-1625, Marjorie Ann Watkins

History Theses & Dissertations

Spectacle and pageantry played an important role in the monarchies of Elizabeth I and James I of England. Generally pageants served reciprocal purposes. It provided a way to let the realm view the state of the monarch's health and allowed the monarch to impress his subjects with royal grandeur. Additionally, it served as a vehicle for the manifestation of the public's desires concerning the direction which the country might move with the accession of a new monarch. Also, civic pageants provide the historian with an indication of popular like or dislike of a sovereign. In this thesis, a considerable amount …

A Nonlinear Hybrid Vortex Method For Wings Having Side-Edge Separations, Li-Chuan Chu

Mechanical & Aerospace Engineering Theses & Dissertations

A Nonlinear Hybrid-Vortex method (NHV-method) has been developed for predicting the aerodynamic characteristics of wings exhibiting side-edge separations. The present method is a coupline between vortex-panel and vortex-line methods. In the near-field calculations, vortex panels are used while in the far-field calculat1ons, vortex lines are used.

The wing and its free-shear layers are divided into planar quadrilateral panels having first-order vorticity distribution. The aerodynamic boundary conditions and continuity of the vorticity distributions are imposed at certain nodal points on the panels. An iterative technique is used to satisfy these conditions to obtain the vorticity distributions and the wake shape as …

The Distribution Of Cesium-137, Copper, Lead And Zinc In Various Sedimentary Environments Of The James River Estuary, Virginia, Colin Stevenson Moy

OES Theses and Dissertations

Ten grab samples and eight cores were obtained within a short stretch of the James River estuary. The distribution of CU, Pb, Zn, Cs-137, organic carbon (TOC) and fine-grained sediments in various depositional environments were examined. Within the past quarter of a century, these measured parameters have been accumulating preferentially in the low energy environment (Burwell Bay). The inventory of Cs-137 in the cores was linearly related to the inventory of heavy metals and TOC. The concentrations of Cs-137 in the surface sediments vary linearly to those of the other parameters suggesting that Cs-137 may be used as a tracer …

Germination And Haustorial Development In Orobanche Minor Smith (Orobanchaceae), David L. Spelce

Biological Sciences Theses & Dissertations

Orobanche minor Smith is an introduced root parasite that is known to attack some commercial crops. Germination occurs only after a preconditioning period involving moisture which must be followed by a chemical stimulant produced by the host root. Strigol and strigol analogs (GR-compounds} have been reported to germinate some species of Orobanche. Statistical tests indicate a significant difference between the effectiveness of strigol, GR-7 and GR-45 (P = 0.001).

The embryo is an undifferentiated mass of cells. During germination, the radicular pole of the embryo differentiates into the radicle, while the plumular pole remains undifferentiated. The radicle forms the primary …

Multiple Forms Of Nicotinamide Adenine Dinucleotide Glycohydrolase From Bull Semen, Stanley D. Yeatts Ii

Chemistry & Biochemistry Theses & Dissertations

Nicotinamide adenine dinucleotide glycohydrolase (NADase) of bull semen is an extracellular, soluble enzyme capable of catalyzing the hydrolysis of the nicotinamide N-ribosidic linkage of NAD⁺. In search for a rapid, simple procedure for the preparation of this enzyme, it was found that Matrex Gel Red A (Amicon) column packing served very well as an affinity gel for NADase. The enzyme was applied to the Matrex Red A column (21 cm x 1.5 cm) in 10 mM sodium phosphate buffer, pH 6.0. Surprisingly, two fractions of NADase activity were obtained when the column was eluted with a sodium chloride …
