Influence Of Diet And Feed Restriction On Kidney Function In Aging Male Rats, Sarah May Tucker

Doctoral Dissertations

The influence of diet and feed restriction on kidney function was studied in aging male albino rats. Rats were fed either a commercial feed (LB) or a modified human diet (MHD) from weaning until sacrifice at either 12 or 24 months of age. Animals sacrificed at 12 months of age were either restricted or fed LB ad libitum from 1 month of age until sacrifice. Animals fed LB and sacrificed at 24 months of age were restricted for one of the following intervals: A, no restriction; R, restriction from 1 month to 12 months; AR, restriction from 12 to 24 …

Lightning Fires In Southern Appalachian Forests, Lawrence Samuel Barden

Doctoral Dissertations

The purpose of this study was to describe characteristics of lightning fires, including frequency, size, season and severity, and to determine their effects on the composition of pine-hardwood stands in the Appalachian Mountains of Tennessee and North Carolina.

An analysis of fire reports from Great Smoky Mountains National Park and from Cherokee, Nantahala and Pisgah National Forests, an area of 800,000 ha, shows that during 1960-1971 there was an average of six lightning fires per year per 400,000 ha (one million acres). The median size of lightning fires was 0.8 ha and the largest 33 ha. More than 90 percent …

Foodways Of Selected Mothers And Their Adult-Daughters In Upper East Tennessee, Kathryn Marianne Kolasa

Doctoral Dissertations

The similarities and differences in the food behavior, food preferences, mass media use, environmental factors and demographic characteristics of 11 selected mothers and their 15 adult-daughters in an homogenous rural area in Upper East Tennessee were studied. The degree of agreement between mother and adult-daughter in the variables named above was associated to their inter-personal communication, age, education and attitudes toward modernity and familism.

A field study method, including the use of repeated interviews, based on an extensive interview-schedule was used to define similarities and differences in behaviors and attitudes of the purposively sampled group of mothers and their adult-daughters. …

Forest Vegetation And Site Relationships In The Central Portion Of The Great Smoky Mountains National Park, Michael Stanley Golden

Doctoral Dissertations

The primary objectives of this study were (1) to apply recently developed quantitative vegetation analysis procedures to the problem of describing the forest vegetation of the central portion of the Great Smoky Mountains National Park, (2) to group samples into forest types based on the importance of a large number of taxa and to compare the results with studies using types defined by relative density or basal area of canopy dominants, (3) to assess and further define the relationships of vegetation pattern with elevation and with topographic characteristics, (4) to examine possible relationships between soil characteristics and vegetation pattern, and …
