Ground-level (tropospheric) ozone (O3) is the most significant phytotoxic gaseous pollutant in the eastern United States. Plants are subjected to acute and chronic exposures of tropospheric O3 that can cause foliar injury ...
Essays on Forestry Products Industry: Sawmill Productivity and Industrial Timberland Ownership
(2006-05-15)
In this dissertation, two topics of forest products industry were investigated: inter-regional productivity comparison of sawmilling industries in the North America, and the relationship between industrial timberland ...
Population Ecology of Northern Bobwhites
(2006-05-15)
The longleaf pine (Pinus palustris) ecosystem is an ecologically significant region of North America, yet its geographic extent has been greatly reduced by several factors including anthropogenic fire suppression. There ...
The effects of tournament fishing on dispersal, population characteristics, and mortaltiy of black bass in Lake Martin, Alabama
(2006-05-15)
A great deal of black bass Micropterus spp. tournament activity occurs at Wind Creek State Park (WCSP), located at the north end of Lake Martin, Alabama. Because of the popularity of this location as a tournament processing ...
Factors Influencing Bioaccumulation of Polychlorinated Biphenyls in Six Fish Species in Logan Martin Reservoir, Alabama
(2006-05-15)
The objective of this project was to evaluate the biological and environmental factors that influenced the bioaccumulation of polychlorinated biphenyls (PCB) in the consumptive portions of fish. I investigated the ...
Variables Influencing Fish Impingement at Five Alabama Power Steam Plants
(2006-05-15)
With increasing need for electricity, steam powered electric generating facilities are increasing across the nation. The cooling water intake structures at these plants are responsible for removing millions of fish and ...
Optimization of Dietary Nutrient Inputs for Pacific White Shrimp Litopenaeus vannamei
(2006-05-15)
A series of studies were conducted with Pacific white shrimp, Litopenaeus vannamei, with the objective of optimizing feed input and improving feeding management strategies to reduce wastes and the potential of negative ...
Characterization of Innate Immune Genes of Catfish: CXC Chemokines and Toll-Like Receptors
(2006-05-15)
Innate immunity is known as the first line of defense against pathogenic invasions. Fish, as lower vertebrates, are believed to maintain their healthy status mostly by relying on their innate immunity. Of the many types ...
Bottom Soil Quality in Ponds for Culture of Catfish, Freshwater Prawn, and Carp in Thailand
(2006-05-15)
Bottom soil samples were collected from 42 catfish (Clarias hybrid) ponds, 40 freshwater prawn (Macrobrachium rosenbergii) ponds, and 18 carp (Puntius spp.) ponds in Thailand. The ponds ranged from 1 to 30 years in age. ...
Modeling of Frictional Gas Flow in a Piezoelectrically Actuated High-Pressure Microvalve for Flowrate Control
(2005-12-15)
One-dimensional modeling of frictional compressible gaseous flow through a high-pressure piezoelectrically-actuated microvalve is studied. Focusing on the micro-scale gap between the boss and seat plates, variations of ...
Overlooked: Dominant Ideology, Limestone County, Alabama Newspapers, and TVA Family Relocation, 1934-1936
(2005-08-15)
The Tennessee Valley Authority’s (TVA’s) construction of Wheeler Dam necessitated the flooding of 52,000 acres of land in Lauderdale, Limestone and Morgan counties in north Alabama. TVA purchased this land from the 835 ...
A Robust Software Radio Testset for Research and Laboratory Instruction
