Biology and management of cut-leaved Teasel (Dipsacus laciniatus L.) in central Missouri
(University of Missouri--Columbia, 2006)Cut-leaved teasel is a biennial invasive weed that grows along roadsides and low disturbed areas. This research was to determine growth characteristics, herbicide efficacy, and seed production of teasel. Growth characteristics ... -
Characterization and functional analysis of the P2Y₂R gene promoter
(University of Missouri--Columbia, 2006)Extracellular nucleotides can bind to the P2Y₂R and modulate proliferation and migration of smooth muscle cells, which is known to be involved in intimal hyperplasia that accompanies atherosclerosis and post-angioplasty ... -
Development of a capillary based helicobacter hepaticus biosensor
(University of Missouri--Columbia, 2006)Helicobacter hepaticus causes hepatitis in mice. Infections with H. hepaticus can invalidate animal research studies and early detection helps curtail the spread of infection. The objective of this study was to develop a ... -
The effects of visiting the Vietnam Veterans Memorial on adjustment to bereavement
(University of Missouri--Columbia, 2006)The lack of grief rituals in the United States has created a culture that is poorly equipped to heal from loss. The ritual of visiting the Vietnam Veterans Memorial has allowed American visitors the opportunity to express ... -
An environmental assessment of sensor-based variable-rate nitrogen management in corn
(University of Missouri--Columbia, 2006)Nitrogen (N) fertilizer unused by the crop is left to the fate of the processes of the N cycle, and can eventually lead to nitrate contamination of surface and ground waters. In order to address this problem, various methods ... -
Evaluation of fecal glucocorticoid metabolite assays for short-term stressors and validation for stress monitoring in African herbivores
(University of Missouri--Columbia, 2006)During stressful periods, glucocorticoid production is increased. Glucocorticoid metabolites are found in blood, urine and feces. Our first goal was to determine if fecal glucocorticoid metabolite (FGM) measurements are a ... -
Evaluation of the efficacy of high levels of microbial phytase in broilers
(University of Missouri--Columbia, 2006)Three experiments were conducted to evaluate the efficacy of high levels of microbial phytase in broiler diets. In experiment one (EXP 1), phytase was included in the diets at 0, 250, 500, 10,000, and 20,000 PU/kg diet. ... -
Factors influencing the college choice of African-American students admitted to the College of Agriculture, Food and Natural Resources
(University of Missouri--Columbia, 2006)The purpose of this study was to describe factors attributing to the college choice of African-American students admitted to the College of Agriculture, Food and Natural Resources (CAFNR) at the University of Missouri - ... -
A genotypic comparison of plasticity of root system development during soil drying in soybean (Glycine max (L.) merrill)
(University of Missouri--Columbia, 2006)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] Water deficit is responsible for significant losses in soybean (Glycine max (L.) Merrill) yield under dryland conditions. Under drought, increases in ... -
Hydrology, vegetation and waterbird response to land management strategies in the San Luis Valley
(University of Missouri--Columbia, 2006)[ACCESS RESTRICTED TO THE UNIVERSITY OF MISSOURI AT AUTHOR'S REQUEST.] The distribution of wetlands in the San Luis Valley has been altered by human modifications that influence the timing, distribution and characteristics ... -
Impact of grazing stockpiled tall fescue of lactating beef cows
(University of Missouri--Columbia, 2006)Two experiments are described, in which fall-calving cow-calf pairs grazed stockpiled tall fescue at three different endophyte infection levels (20, 51, and 89%) and four forage allowances (2.25, 3.00, 3.75, and 4.50% of ... -
The influence of teacher efficacy on North Carolina Agriculture teachers' perceived success in working with students with special needs
(University of Missouri--Columbia, 2006)Most agriculture teachers do not feel competent when working with students with special needs (Elbert & Baggett, 2003). The purpose of this study was to examine and explain the variance in the self-perceived success of ... -
Ion-selective electrodes for simultaneous real-time analysis for soil macronutrients
(University of Missouri--Columbia, 2006)Automated sensing of soil macronutrients (i.e., N, P, and K) would allow more efficient mapping of soil nutrient variability for variable-rate nutrient management. This study reports on the development of a sensor array ... -
Macroinvertebrate and crayfish communities in the Meramec River drainage basin: an investigation at multiple spatial scales
(University of Missouri--Columbia, 2006)Hierarchical classification systems have been widely used to delineate terrestrial ecounits at multiple spatial scales; however there has long been a need for an aquatic based classification system. A newly developed aquatic ... -
Non-operator and farm operator landowner interest in agroforestry in Missouri
(University of Missouri--Columbia, 2006)Farmers are increasingly conflicted between maintaining the integrity of the land and trying to succeed in a competitive market place. Agroforestry may offer opportunities, but awareness of the various practices is very ... -
A novel PCR based DNA microanalyzer system for detection of viral genome
(University of Missouri--Columbia, 2006)A micro-fluidic assay to quickly analyze microscopic samples of DNA is being developed for field applications. It consists of a micro-PCR chamber, micropumps, and micro-heaters. Additional components of the device include ... -
Relation of Missouri river flows to sandbar morphology with implications for selected biota
(University of Missouri--Columbia, 2006)Channel modification and flow regulation in historically braided large rivers, have reduced sandbars and associated highly productive habitats for riverine biota. Sandbars are an important interface between aquatic and ... -
