Exposure to explicit sexual media impacts men's perceptions of women's motives for sexual intercourse [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Previous studies have shown that exposure to sexually explicit media can influence males' attitudes toward sex and their sexual partners, their behaviors, and their emotions. Researchers found increased aggression towards ...
Thrust and torque response for drilling titanium and carbon composite sandwich materials [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Experiments were conducted based upon previous research conducted by El-Gizawy and Khasawneh [1] to determine the time response of thrust force and torque correlated to a simple drilling procedure through carbon fiber ...
South Korea protein demands [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Over the last 10 years South Korea has had experienced a steady increase in population averaging an increase of approximately 1% a year. They have also been able to acheive economic growth with a GDP that is almost two and ...
Public perceptions of the environment: The role of mass media [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
This project examines the relationship between television news coverage of environmental issues and variations in public concern for the natural environment in the United States. Aggregate-level, time series data (GSS; ...
Target test tube assembly process and design for the development of molybdenum-99 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Molybdenum-99 (Mo-99) is used to create Tc-99m, a widely used nuclear medicine diagnostic imaging radioisotope. In an attempt to decrease the need for imported Mo-99, development of mechanical systems to efficiently prepare ...
Establishing the status of the American black bear in southern Missouri [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The current status of the black bear population in Missouri is largely unknown, as we have little to no information concerning its size, reproductive status and origin. However, evidence suggests that the bear population ...
Are age-related differences in associative memory mediated by sensory decline? [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Naveh-Benjamin (2000) suggested an associative deficit hypothesis, explaining that some of the decline in episodic memory in older adults is due to their difficulty in binding unrelated components together into a cohesive ...
Regulation of menaquinone production in Desulfovibrio vulgaris Hildenborough and Desulfovibrio desulfuricans strain G20 [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Menaquinones are cytoplasmic membrane components that have important roles in electron transport for energy generation in anaerobic bacteria. A simple and sensitive protocol for the purification and quantification of ...
The formation of cysteine-tyrosine crosslinks via a sulfenic acid intermediate [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Cysteine residues in proteins are readily oxidized to sulfenic acids. Sulfenic acids, in turn, can act as potent electrophiles that have been observed to form intrastrand protein crosslinks with neighboring amide or cysteine ...
Plasma surface modification of silica particles for the increased strength of dental composites [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Many of the problems that exist today with current dental restoration materials can be eliminated through the use of nanofiber fillers such as hydroxyapatite. Materials like this can ultimately provide greater strengths ...
Characterizing the role of Glycine max NHL gene family members in plant-nematode interactions [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Soybean cyst nematode (SCN; Heterodera glycines) is a microscopic parasitic roundworm of soybean that causes nearly $1 billion dollars in annual yield loss in the United States. SCN damages the plant by attaching itself ...
Protecting biodiversity: Riparian buffers directly affect Appalachian headwater salamanders [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Salamanders are the most abundant invertebrate predator in the southern Appalachians; they have the highest biomass, and they are an important species for scientific investigators. Their permeable skin and eggs makes them ...
Developing a nowcasting technique for splitting supercells by analyzing rapid update cycle model data [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
The goal of this research project was to develop a nowcasting technique, or to at least find out which parameters are changed to help supercells split. This was first completed by overlaying Rapid Update Cycle (RUC) model ...
The construction of neoliberalism and its effect on Mexican water policy [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
After the debt crisis of 1982, Mexico began implementing neoliberal policy, which culminated in the ratification of the North American Free Trade Agreement (NAFTA). The neoliberal reforms fundamentally changed environmental ...
Comparison of the progression of glomerulosclerosis between Oim-C57BL/6 and Oim-B6C3Fe a/a [abstract]
(University of Missouri--Columbia. Office of Undergraduate Research, 2008)
Osteogenesis Imperfecta (OI), a heritable connective tissue disorder, resulting from mutations in the type I procollagen genes is characterized by bone deformity and fragility. The OI mouse model (oim) is homozygous for a ...
