Effects of forest management practices on treefrog oviposition site choice
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Globally, amphibian populations are declining faster than those of birds or mammals. Habitat destruction is considered the primary cause of these declines; however, what remains partly unexplored is the idea that some ...
The synthesis of peptide-PNA conjugates
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
In two long term studies of non-Hodgkin's Lymphoma (NHL), the only clinical feature associated with a high relapse rate and treatment resistance is the presence of the B-cell lymphoma/leukemia-2(bcl-2) proto-oncogene in ...
Effect of feed restriction and hypothermia on fetal mice
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Low birth weights result in high mortality in highly prolific pigs. Anecdotal evidence in sheep and cattle suggests restricting feed early in gestation and/or cooling late in gestation increase birth weights. Therefore, ...
Conversion of waste corn cobs to activated carbons for natural gas (methane) adsorption
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Adsorbed Natural Gas (ANG) is an alternative energy source technology that uses micropores in adsorbent materials to store natural gas. Activated carbons, which are useful adsorbents with a highly porous form of carbon are ...
Developing proteomics approaches for identifying new, redox-regulated proteins
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
For many years it was thought that hydrogen peroxide was only a toxic substance to cells. However, recent work has revealed that hydrogen peroxide can be utilized by organisms as a cellular signaling molecule. Hydrogen ...
Retension of knobs in chromosome tips in maize
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Knobs are deeply staining chromosomal sites on maize chromosomes. Molecularly, they are composed of a 180 base pair repeat. Their positions on the chromosomes are variable but usually internal in maize. In relatives, the ...
Death by the pounds: The effects of television on the obesity of African-American children and adolescents
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study examined the direct effects that television programming has on the obesity of African-American children and adolescents based upon the top three stations viewed by African-American children and adolescents during ...
The effect of timber stand improvement practices on the abundance of Pileated Woodpeckers
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The Pileated Woodpecker (Drycopulus pileatus) is a large woodpecker that requires large dead trees within a mature forest. I investigated how forest management practices affect the Pileated Woodpecker. Timber stand improvement ...
Expression of ISG15, UBE1L and MX2 in white blood cells of early pregnant and bred-nonpregnant dairy cows
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Identifying pregnant and nonpregnant cows shortly after insemination can improve reproductive efficiency in dairy cows if resynchronization is practiced on nonpregnant cows. Bovine Interferon Stimulated Gene Product 15 ...
Characterization of a putative mutant for iron homeostasis
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Little is known about the genetics of iron homeostasis in plants. A novel genetic screen was used to identify mutants with alterations in iron homeostasis. Because Ferritin (Fer1) mRNA expression is upregulated by intracellular ...
Storing hydrogen, by enhancing diamond powder properties with CaF2 and KF for use in fuel cells
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Whaaaat!!!!!!!!! Hydrogen as a fuel? Yes just like you read it, hydrogen is becoming the best alternative to change our economical dependence on fossil fuels. Today fossil fuels are the main source of energy in the world, ...
A study of teen pregnancy: At-risk teens and their motivation to stay in school
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
This study utilized Deci and Ryan's self-determination theory of motivation to examine pregnant and parenting teenage girls who attended an alternative education program in Kansas City, MO and mainstream high schools in ...
Parameter estimation and data reduction for cellular biophysical analysis
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Accurate estimation of cellular permeability parameters are an important part of designing and developing optimized cryopreservation protocols. Electronic Particle Counters measure cell volume by detecting changes in ...
Progress in the synthesis of a Technetium-labeled complex as a potential Sigma receptor binding ligand
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
The sigma receptors have been known to affect several physiological functions such as psychosis, depression and uncontrolled cell proliferation. But what makes the sigma receptors so great is the fact that they bind a ...
Single component vs. whole furniture packing in virtual reverse manufacturing
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Previous research studies have analyzed the issues associated with the computer integration of the various technologies now available for hardwood log sawmills. These new technologies were created to optimize the quantity ...
L-NAME treatment in pigs
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Nω-nitro-L-arginine-methyl-ester (L-NAME) inhibits the enzyme nitric oxide synthase (NOS) which generates the physiologic messenger gas, nitric oxide (NO). In addition to its role as a vasodilator NO inhibits inflammation ...
Effect of clearcutting on the habitat within the clearcut and the surrounding forest and its relationship to the presence of wood thrush (Hylocichla mustelina) in the Current River Conservation Area
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Wood thrush were one of the few species of forest birds that increased in density on sites that received even-aged management as part of the Missouri Ozark Forest Ecosystem Project (MOFEP). One hypothesis is that this may ...
Doping of natural diamond powder with boron to increase its hydrogen storage capacity
(University of Missouri--Columbia. Office of Undergraduate Research, 2005)
Have you asked yourself what will happen when we run out of fossil fuels, where will our electric power come from, how would we be able to transport ourselves over long distances? Think about what will happen to our economy ...
