Doctoral Dissertations

Mature ewes were equipped with catheters in the portal, hepatic, mesenteric and femoral veins and femoral artery. Blood flows were measured by infusing a 1.5% solution of para-aminohippurate into the mesenteric vein at .764 ml/min. Net fluxes of metabolites were calculated by multiplying veno-arterial differences by tissue blood flows.

Study 1. Twenty experiments were conducted on five ewes to determine the effects of fungus-infested fescue hay on energy nutrients and regulatory hormone net fluxes. Ten experiments were conducted for each a fungus-free and fungus-infested fescue hay diet. Fungus-infested hay decreased arterial concentrations of acetoacetate and B­ hydroxybutyrate by 15 and …

Effect Of Using And Reusing Melt-Blown, Microwavable Materials To Heat Frozen Fish Filets: Objective And Sensory Perspectives, Patricia J. Cochrane

Masters Theses

Frozen fish filets were heated in the microwave oven on polyester and polypropylene melt-blown materials. Paper towels were used as the control. After heating, all filets were analyzed for fat and moisture retention. Materials were stored under refrigeration temperatures (18^oC) or freezing temperatures (0^oC) and reused. Polypropylene melt-blown materials used once absorbed significantly more fat than polyester melt-blown materials used once. Neither absorbed more fat than paper towels. Total cooking losses, evaporative losses, and moisture retention of fish filets were not significantly different among the melt-blown materials or paper towels. Reused melt-blown materials absorbed significantly more …

Distribution Of The Fishes Of The Great Smoky Mountains National Park, Damien J. Simbeck

Masters Theses

Over 200 collections of fishes have been made within the boundaries of the Great Smoky Mountains National Park, revealing a Park ichthyofauna of 74 native and 5 introduced fish species. Abrams Creek, containing the most diverse ichthyofauna in the park, currently contains only 35 of its historical 67 fish species. This loss of species resulted from intentional poisoning of eh creek to improve habitat for rainbow trout and impoundment of the lowest 2.6 miles by Chilhowee Reservoir.

Abrams Creek also contains a very unusual ichthyofauna in its upper portion. Several species found above its 25-foot waterfall have not been found …

The Life History Of The Flame Chub, Hemitremia Flammea (Jordan And Gilbert), In Pond Creek, Loudon County, Tennessee, Marcia K. Sossamon

Masters Theses

Life history data were obtained from 243 preserved specimens of the flame chub, Hemitremia flammea, collected from June 1989 to June 1990 at Pond Creek in Loudon County, Tennessee. Flame chubs had a life expectancy of 1.5 years, and some individual reached 2 years. Length-weight relationships showed that as the length of the flame chubs increased, their weight did not increase as much as most other fish. During the spawning season, females averaged larger than males and outnumbered them. Flame chubs spawned between January and June, peaking in March. Fecundity generally increased as the total length of the female …

The Reproductive Biology, Winter Dormancy And Denning Physiology Of Black Bears In Great Smoky Mountains National Park, Stephen Anthony Pozzanghera

Masters Theses

Black bear reproduction, winter dormancy and denning physiology were studied during June 1984 to May 1986 in the northwest quadrant of Great Smoky Mountains National Park, Tennessee. Information was obtained from 30 individual females captured 35 times. Additional information on mast indices, lactation and den utilization were summarized from within the study area for the period from 1978-1988.

Breakaway collar retention varied significantly between years (1984, N=10, X=394 days vs. 1985, N=5, X=196 days, P<0.05).

Maximum production potential indices calculated for white, red and all oaks for 1984 and 1985 were 8.74, 19.99, 15.52%, and 35.06, 37.73, 36.45%, respectively. Regression …
