Applications of gel electrophoresis in quantum dot conjugates' separation and purification
(University of Missouri--Columbia, 2009)The objectives of this study were to build Quantum dot (QD) crosslinker complexes for antibody conjugation usage, to purify QD crosslinker complexes by gel electrophoresis and to check the biological functionalities of ... -
Are structural changes in the agri-food sector causing the instability of parochial ag-producers?
(University of Missouri--Columbia, 2009)Parochial (Amish and Mennonites) agriculture producers have been known for their stability (historically large numbers) (Kollmorgen, 1943). Though, more recently, the percentage of parochial members who are ag-producers ... -
Classification of air pollution regimes in the Missouri region
(University of Missouri--Columbia, 2009)High levels of ground level ozone have been linked to large-scale weather patterns both at the surface and in the upper atmosphere. For this reason, the main focus of this study was to analyze the atmospheric conditions ... -
Cognitive load and time based forgetting
(University of Missouri--Columbia, 2009)Recently, various researchers have claimed that time does not play a direct role in shortterm forgetting. Instead, they claim that time is only related to forgetting because it is correlated with other factors that cause ... -
Concealed authorship on the eve of the revolution : pseudonymity and the American periodical public sphere, 1766-1776
(University of Missouri--Columbia, 2009)Concealed authorship played a vital role in the critical ten years prior to American independence. Authors utilized printers as cover to publish political essays seditious and disruptive to British authority. Pseudonymity, ... -
Condition assessment of carbon fiber composites using raman spectroscopy
(University of Missouri--Columbia, 2009)The goal of this research is to examine the potential of Raman spectroscopy as a method of condition assessment for carbon fiber composite materials. Carbon fiber composites are used in high performance situations such as ... -
Determination of trace elements levels in plasma from larvae in the course of baculoviral and bacterial infections by inductively coupled plasma-mass spectrometry (ICP-MS)
(University of Missouri--Columbia, 2009)While a number of studies have examined the effect of infections on the trace elements status of mammals, not any similar study in insects are found. In this study, we used inductively coupled plasma-mass spectrometry ... -
Developing, implementing, and assessing coupled-tank experiments in an undergraduate chemical engineering curriculum
(University of Missouri--Columbia, 2009)Five experimental modules that fit into the Undergraduate Chemical Engineering Curriculum were developed using the existing Coupled-Tank Apparatus. Students of different educational levels get an opportunity to develop ... -
Development and application of vegetative buffer width modeling using geographic information systems
(University of Missouri--Columbia, 2009)It has been widely accepted that vegetative buffers are effective in removing nonpoint source pollutants. However, problems focusing on vegetated buffers studies remain, especially in technical aspects (i.e., how to design ... -
Development of a post-traumatic osteoarthritis model to evaluate the effects of impact velocity and maximum strain on articular cartilage cell viability, matrix biomarkers, and material properties
(University of Missouri--Columbia, 2009)Post-traumatic osteoarthritis (PTOA) is a very painful and debilitating disease that is associated with mechanical injury to articular cartilage, yet the severity of trauma required to induce it is unknown. The objective ... -
The effect of avatars on perceived credibility of comments posted to online news stories
(University of Missouri--Columbia, 2009)An experiment tested two two-part hypotheses predicting the effect of specific avatar features -- avatar humanness and eye contact -- on perceived credibility of related comments about online news stories. Participants ... -
Effect of high peroxide value fats on performance of broilers in normal and immune challenged states
(University of Missouri--Columbia, 2009)A series of trials were conducted in order to determine the effects of high peroxide value fats on performance of broilers in normal and immune challenged states from 0-49 days of age. In the first experiment, birds were ... -
Effects of heat stress on reproduction and productivity of primiparous sows and their piglets' performance
(University of Missouri--Columbia, 2009)Heat stress (HS) produces seasonal infertility in sows and decreases reproductive efficiency. Sows were exposed to HS during a production cycle (gestation [gest], lactation [lact], and breeding) to examine productivity. ... -
Effects of low crude protein diets with amino acid supplementation on broiler performance in the starter period
(University of Missouri--Columbia, 2009)A series of experiments were conducted to examine the effects of feeding low crude protein (CP) corn and soybean meal diets with crystalline amino acid supplementation to broilers from 0-3 weeks of age. It was hypothesized ... -
Efficacy of oriental mustard (Brassica juncea L. Czern.) seed meal for weed and disease control in turf
(University of Missouri--Columbia, 2009)Pest management in turf involves the use of fumigants such as methyl bromide, as well as selective pesticides. However, the loss of methyl bromide and development of disease resistance to fungicides suggests that more ... -
Evaluation of patch-burn grazing on species richness and density of grassland birds
(University of Missouri--Columbia, 2009)A patch-burn grazing (PBG) management technique was applied to four native tallgrass prairies in southwest Missouri to evaluate its effect on species richness and density of grassland birds. Treatment prairies were spring ... -
Evaluation of the service performance of an innovative precast prestressed concrete pavement
(University of Missouri--Columbia, 2009)Precast prestressed concrete pavement (PPCP) is the product of an optimization of conventional materials coupled with economical fabrication and transportation means to create a product that exceeds the performance and ... -
