The mechanisms that control the mass transfer of gases across the air-water interface are not well understood. Current models for air and water gas transfer have limited effectiveness because they are based on large scale ...
Effect of Kisspeptin on the Hypothalamic-Pituitary-Gonadal Axis of the Mare
(2008-12-15)
Kisspeptin, a neuropeptide product of the KiSS-1 gene, has recently been shown to control the timing and release of gonadotropin releasing hormone (GnRH) from the hypothalamus in laboratory animals and move anestrus ewes ...
Therapeutic Vaccines against Chlamydial Diseases
(2008-12-15)
Subclinical infections with intracellular bacteria of the family Chlamydiaceae cause substantial losses in animal agriculture. To validate the feasibility of therapeutic vaccination against chlamydial infection and disease, ...
Clinical, Biochemical, and Molecular Aspects of Glanzmann Thrombasthenia in Horses
(2008-12-15)
Glanzmann thrombasthenia (GT) is an autosomal recessive bleeding disorder that is caused by a quantitative or qualitative deficiency in platelet membrane glycoprotein complex IIb-IIIa (integrin aIIbß3), also known as the ...
Population Dynamic Modeling of the Corkscrew Sea Anemone Bartholomea Annulata on Caribbean Coral Reefs
(2008-12-15)
The corkscrew anemone Bartholomea annulata is a large, common sea anemone on Caribbean coral reefs. The holobiont of B. annulata, endosymbiotic microalgae (zooxanthellae), and ectosymbiotic cleaner shrimps may have positive ...
Habitat Associations Among Bats on Redstone Arsenal, Alabama
(2008-12-15)
As forests become more fragmented, more research about use of forests by bats at the landscape level is needed. I employed 2 methods to investigate use of forest by foraging bats; mist-net surveys and ultrasonic-detection ...
Ecological Associations of Bats (Mammalia: Chiroptera) in the Upper Mobile-Tensaw River Delta, Alabama
(2008-12-15)
Relatively little is known about most of the 15 species of bats in Alabama. Especially scarce are data on species occurring in southern Alabama, including the Mobile-Tensaw Delta region. Because there are significant ...
Pyridoxine (Pyridoxamine) 5'-phosphate Oxidase in Arabidopsis Thaliana
(2008-12-15)
Vitamin B6 is the collective term for a group of three related compounds, pyridoxine (PN), pyridoxal (PL) and pyridoxamine (PM), and their phosphorylated derivatives, pyridoxine 5'-phosphate (PNP), pyridoxal 5'-phosphate ...
Characterizing Grass-Fed Ground Beef and Enhanced Steaks Using Modified Atmosphere Packaging
(2008-12-15)
Fall-born Angus x Continental crossbred steers (n = 18) were randomly assigned to six 1.4 ha paddocks with 3 head in each paddock. The paddocks had been randomly planted with Marshall Ryegrass (Lolium multiflorum L.), ...
Southern-Pine Silvopasture Systems: Forage Characteristics, Soil Quality, and Landscape Utilization by Cattle
(2008-12-15)
Silvopasture is considered a more attractive land management option for diversified economic returns and environmental quality compared to open-pasture (pasture without trees) monocultures. However, little is known about ...
Fertilizer Value of Densified Broiler Litter
(2008-12-15)
The increase in broiler (Gallus gallus domesticus) production across the southeastern United States and in the state of Alabama has led to locally excessive application rates of broiler litter. Because of the low fertilizer ...
Growing Naturally in Alabama: Needs and Possibilities
(2008-12-15)
The emergence of the term 'organic farming' describes a distinct system of agriculture compared to conventional or industrial agriculture. Since October 2002, farmers planning to market their products as ΄organic‘ must be ...
Irrigation, Income Distribution, and Industrialized Agriculture in the Southeast United States
(2008-12-15)
Improved availability of irrigation water in agriculture can stabilize crop yields and therefore incomes for adopting producers. However, because of unequal distribution of access to land and water, irrigation may have ...
Optimization of Fuel-Air Mixing for a Scramjet Combustor Geometry Using CFD and a Genetic Algorithm
(2008-12-15)
A new methodology for the optimization of fuel-air mixing in a scramjet combustor using integrated Genetic Algorithms and Computational Fluid Dynamics is presented. A typical combustor design involving Mach 2 crossflow ...
Design and Testing of a Gas Distribution Method for Pulsed Inductive Thrusters
(2008-12-15)
A gas distribution manifold for use in a Pulsed Inductive Thruster has been designed and tested. The Argon test gas is distributed radially outward over a flat disc from an enclosed manifold area. The manifold was designed ...
A Feedback Linearization Approach for Panel Flutter Suppression with Piezolectric Actuation
(2008-12-15)
A panel is subject to dynamic instability when induced aerodynamic loads under the
supersonic/hypersonic environment result in a self-excited oscillation called panel flutter. The panel of an aircraft that flies at ...
