Identification of heat tolerant upland cotton (Gossypium hirsutum L.) germplasm utilizing chlorophyll fluorescence measurement
(2013-07-16)
Heat stress adversely affects upland cotton (Gossypium hirsutum L.) production in the U.S.. A low level of genetic variability in domesticated upland cotton is one of the major constraints for cotton germplasm improvement. ...
The Effect of City-County Consolidation in South Korea
(2013-07-16)
In 1994, the South Korean central government initiated a massive merger of city and county governments, and during the next two years, a total of 40 consolidated cities were established. Following the city-county consolidations, ...
Human melanocortin-4 receptor: structure-function relationship of transmembrane domain 3 and biased signaling
(2013-07-15)
The melanocortin-4 receptor (MC4R) is a G protein-coupled receptor critical for maintaining energy homeostasis. Transmembrane domain 3 (TM3) of MC4R contains residues that are suggested to be essential in ligand binding ...

(2013-07-15)
Increased demand in transportation fuels, environmental concerns and depletion of fossil fuel require development of efficient conversion technologies for second-generation biofuels. In this dissertation, sub- and supercritical ...
Biology of Blaptica dubia (Blattodea: Blaberidae)
(2013-07-15)
The Dubia Cockroach, Blaptica dubia Serville, has become a popular food choice among amphibian and reptile enthusiasts. However, there has been little scientific research conducted on this species. My research consists of ...
Does chronic leptin treatment decrease glucagon responsiveness in STZ-induced type 1 diabetic rats?
(2013-07-15)
Central administration of leptin normalizes blood glucose (BG) concentrations in streptozotocin (STZ)-induced diabetic rats. We hypothesize that this is due to a leptin-mediated decrease in glucagon responsiveness.
Male ...
