(Texas A&M University, 2013-02-22)The command to "Know thyself," ascribed to Greek wisdom, and further propounded by Socrates' proclamation "the unexamined life is not worth living" suggests that the prerequisite for life extends beyond mere existence to ...
-
(1980)The utility of external and cranial measurements to distinguish between specimens of Peromyscus leucopus and P. gossypinus from East Texas was assessed. The extent of age, sexual, and individual variation was statistically ...
-
(1991)An 11 Kbp SstI fragment has been identified which is capable of complementing a brlA⁻ deletion mutant when inserted at the trpC locus in Aspergillus nidulans. Deletions of the SstI fragment indicate that sequences as much ...
-
(1993)In 1991, the neurotoxin, domoic acid, contaminated northern anchovies (.Engraulis mordax Girard) in Monterey Bay, California. Over 100 brown pelicans and Brandt’s cormorants died after consuming the contaminated anchovies. ...
-
(2011-04-29)The objective of this study was to map quantitative trait loci for feed efficiency in Bos taurus indicus x Bos taurus taurus crossbred steers. Steers (n = 231) were from 13 full-sibling embryo transfer Nellore-Angus F2 ...
-
(1995)The tightly linked ripening-inhibitor (rin) and macro calyx (mc) loci represent two important developmental genes in tomato fruit ripening and flower development, respectively. Map-based cloning experiments are currently ...
-
The identification of recurrent tertiary motifs by interactions of protein secondary structure units (Texas A&M University, 2013-02-22)Proteins are the molecular machines that drive the processes of the cell; they carry out the functional and structural instructions outlined in an organism's genome. At their simplest, these biological catalysts are comprised ...
-
(Texas A&M University, 2013-02-22)Neural tube defects (NTDs) are common human congenital anomalies affecting 1 per 1000 live-born infants in the United States. NTDs are medical conditions that result from improper formation of the brain and spinal cord. ...
-
(Texas A&M University, 2013-02-22)In recent years, the enzyme telomerase has been found to be very active in human cancer cells but not in normal cells in the body. This discovery is predictable, as telomerase is responsible for maintenance of the telomeres ...
-
(1994)The first step in catecholamine biosynthesis is the hydroxylation of tyrosine to form dihydroxyphenylalanine (DOPA). This step is rate-limiting and is catalyzed by the enzyme tyrosine hydroxylase. This enzyme binds heparin ...
-
(1979)One of the types of risk encountered in petroleum investments is political risk. Political risk is the probability of changes in the business environment due to political changes. There exists a need to treat analysis of ...
-
(2011-08-15)This research utilizes the methodology of qualitative research to investigate the drinking habits and culture of two countries: Italy and the United States. The thesis highlights statistical evidence provided by the two ...
-
(2001)The role of anachronism (ana) protein in stem cell division of Drosophila melanogaster was examined. Synthesis of identifiable ana protein was necessary. The identifying method exploited was that of antibody tagging using ...
-
(Texas A&M University, 2013-02-22)In order to determine whether Euro-American teachers over-perceive aggression in African-American children, peer ratings of aggression were obtained via a modified version of the Revised Class Play (Masten, Morrison, & ...
-
(Texas A&M University, 2013-02-22)The tomato has been an agriculturally important crop for centuries. For that reason, learning about the fundamental biochemistry and physiology of the plant has been an active research area for decades and has lead to ...
-
(2007-07-14)Not all independent voters are the same. Some independents lean toward a political party and are therefore called “independent leaners.” The objective here is to uncover what forces cause independent leaners to retain some ...
-
(1988)America has historically been a land of progress and hope. Consequently, American society is future-oriented. Because of this, the myth of the apocalypse – especially visions of the end of the world – is fundamental to the ...
-
(1976)Immunization against learned helplessness has been found in dogs and rats; this study tested for the same effect in man. College students were divided into four groups; the helplessness control group received no immunization ...
-
(1998)Prior exposure to shock lowers vocalization thresholds to heat and facilitates the acquisition of conditioned fear when training is conducted in a different context. These observations have been taken as evidence that shock ...
-
(1993)Previous research has shown that exposure to inescapable shock produces a hormonally mediated opioid hypoalgesia in rats. In addition, it has a long-term sensitization effect on the opioid system that increases reactivity ...
