Comparative transcriptional profiling of the uterus according to stage of the estrous cycle and pregnancy status in gilts
(University of Missouri--Columbia, 2007)In most mammals, female reproductive tracts undergo extensive tissue remodeling throughout the estrous cycle and during pregnancy that arise in response to an array of endocrine, paracrine, and autocrine signals. These ... -
Comparison of rainfall energy and soil erosion parameters from a rainfall simulator and natural rain
(University of Missouri--Columbia, 2007)Numerous studies have used artificial rainfall to quantify relationships for runoff and soil detachment. Application of these results to natural rainfall conditions is dependent in part on how well artificial rainfall ... -
Comparison of sensory characteristics, and instrumental flavor compounds analysis of milk produced by three production methods
(University of Missouri--Columbia, 2007)The objectives of this research were to carry out an analytical and sensory comparative studies on the flavor constituents of milk from three production systems: organic (O), pasture-feed based system (P), and conventional ... -
Determining the efficacy of a biosensor to detect calpastatin, a meat tenderness indicator
(University of Missouri--Columbia, 2007)An instrumental tenderness detection system used at the time of grading to sort beef carcasses on their predicted tenderness would be valuable for the beef industry. A biosensor to accurately predict calpastatin, the ... -

(University of Missouri--Columbia, 2007)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT REQUEST OF AUTHOR.] Millions of individuals are diagnosed each year with Human Immunodeficiency Virus Type 1. Each day more individuals are receiving antiretroviral ... -
Dissipation and carryover of imidazolinone herbicides in imidazolinone-resistant rice (Oryza sativa)
(University of Missouri--Columbia, 2007)The development of Imidazolinone (IMI) Resistant (IR) rice now allows rice producers to selectively control red rice (Oryza sativa, O. rufipogon, and O.nivara), weedy relatives of commercial rice (O. sativa). Imazethapyr ... -
DNA methylation in the early porcine embryo
(University of Missouri--Columbia, 2007)Reproductive technologies such as in vitro fertilization, intracytoplasmic sperm injection, parthenogenetic activation, and somatic cell nuclear transfer are powerful procedures in the production of animals for agriculture, ... -
Effect of problem-based learning on knowledge acquisition, knowledge retention, and critical thinking ability of agriculture students in urban schools
(University of Missouri--Columbia, 2007)The purpose of this study was three-fold: to determine the effectiveness of instructional strategies on improving the acquisition and retention of leadership content by secondary students in urban agriculture programs; to ... -
Effect of swine diets supplemented with magnesium sulfate and electroytes on pork quality
(University of Missouri--Columbia, 2007)Market hogs (n = 160) were allotted into four dietary treatments to evaluate the effectiveness of magnesium sulfate and electrolytes on improving pork quality. The experiment was conducted in four seasons to evaluate ... -
The effect of weed density, root senescence, and egg density on western corn rootworm larval establishment, survivorship, and damage potential
(University of Missouri--Columbia, 2007)Western corn rootworm, Diabrotica virgifera virgifera Leconte beetle emergence from and root damage to transgenic (Bt) maize (Zea mays L.) plants producing the Cry3Bb1 protein and isoline plants in the presence of varying ... -
An empirical approach to exploring the role of selective incentives in mitigating the free rider problem
(University of Missouri--Columbia, 2007)The concept of free riding has been recognized as a challenge facing collective action organizations for centuries. However, the term free riding has been used to describe a range of alternative problematic actions and ... -
Estrus induction and maintenance of cycles in gilts with PG-600 and boar exposure
