The abundance and diversity of stream salamanders on montane golf courses
(University of Missouri--Columbia, 2012)Stream salamanders are often the most abundant vertebrates in headwater streams and they play an integral role as both predators and prey in these ecosystems. Because they often use both terrestrial and aquatic habitat and ... -
Active and Healthy Schools pilot program in two private Missouri K-8 elementary schools
(University of Missouri--Columbia, 2012)Introduction. Overweight and obesity increase individuals risk for chronic diseases. In 2009, 14% of Missouri ninth to twelfth graders were overweight. This study examined the efficacy of Active and Healthy Schools (AHS) ... -
Authentic thresholds : interior design client involvement in the creation of sense of home
(University of Missouri--Columbia, 2012)For middle-class householders interested in elevating an image of their status, residential interior designers may be viewed as destroyers of authentic sense of home. By contrast, designers may seek to contribute to the ... -
Biomass assessment in the U.S. midwest using MODIS time-series
(University of Missouri--Columbia, 2012)Bioenergy becomes the largest source of renewable energy in the United States. Switchgrass, a type a Warm Season Grasses, has been regarded as alternative resources instead of annual crops for obtaining the bioenergy. The ... -
Characterization of a soybean BAG gene and its potential role in nematode resistance
(University of Missouri--Columbia, 2012)Plants resistant to the soybean cyst nematode (SCN) mount a hypersensitive cell death-like response upon nematode feeding, but the genes regulating this process are not known. Laser-assisted microdissection of nematode ... -
Combined dilatometry and mass spectrometry of sintering and evolved gases of barium titanate and zirconium diboride with sintering additives
(University of Missouri--Columbia, 2012)A combined dilatometer mass spectrometer system (CDMS) is used to monitor the gas phase species and sintering progress in real time during the heating of barium titanate and ultra high temperature ceramics (UHTCs), including ... -
Comparison of long-term CIDR-based protocols to synchronize estrus and ovulation prior to fixed-time artificial insemination in postpartum beef cows
(University of Missouri--Columbia, 2012)This experiment compared two long-term CIDR-based protocols to synchronize estrus and ovulation prior to fixed-time AI (FTAI) in postpartum beef cows. Cows assigned to the 14-19 d CIDR-PG protocol (n = 196) received CIDR ... -
Computational studies of methane adsorption in nanoporous carbon
(University of Missouri--Columbia, 2012)In this thesis we have completed computational studies using Grand Canonical Monte Carlo on the adsorption of methane into a graphitic nanoporous adsorbent with slit-shaped pores. Simulations were done at a temperature of ... -
Control of Bermudagrass (Cynodon dactylon) in Zoysiagrass (Zoysia japonica) turf by using post-emergence herbicides
(University of Missouri--Columbia, 2012)Bermudagrass and zoysiagrass are two commonly used turfgrass on golf course fairways in the southern and transition zone of the United States. Due to its excellent turf performance and superior cold tolerance compared to ... -
Cultural values mediate the effect of parenting styles on Mexican American adolescents' prosocial behaviors
(University of Missouri--Columbia, 2012)The aim of this study was to examine the relations between supportive and strict parenting, traditional Mexican American culture values (respect and traditional gender roles), and prosocial tendencies in Mexican American ... -
Design and analysis of a metamaterial with high refractive index at dual band frequencies
(University of Missouri--Columbia, 2012)The concept of a single frequency band, single high-refractive-index metamaterial has been extended and applied in the design of dual frequency band, dual high-refractive-index metamaterials in the THz regime. The structure ... -
Design and experimental study of a dual vircator microwave source
(University of Missouri--Columbia, 2012)The research described in this thesis details the design, construction, and experimental results in developing a virtual cathode oscillator (vircator) high power microwave (HPM) source. The HPM source utilizes two independent ... -
Designing and modeling a split torque hydrostatic transmission in series with a manual transmission for an automotive application
(University of Missouri--Columbia, 2012)Increasing petroleum prices have developed a strong demand for an invention to reduce fuel consumption, as well as cut the produced amount of carbon dioxide via consumed fuel. Hybrid vehicles are an effective invention in ... -
The economic feasibility of woody biomass harvest practices in Missouri : the cost of harvesting tops and small diameter trees
(University of Missouri--Columbia, 2012)Woody biomass materials which include timber harvest residues, such as tree tops and small diameter trees, have the potential to be an important source of renewable energy. Their use as an energy feedstock or use as an ... -
Effects of calcium-rich additives on the small-strain modulus of representative subgrade soils in Missouri
(University of Missouri--Columbia, 2012)Calcium rich additives, such as fly ash and lime kiln dust, can improve the mechanical properties of subgrade soils, resulting in better performance and more economical pavement design. Use of calcium-rich additives in ... -
The effects of dopamine and salience manipulations on magical thinking
(University of Missouri--Columbia, 2012)Although delusional and magical thinking is associated with both increased dopamine and aberrant salience, it is unknown whether dopamine manipulations cause increased magical thinking on non-clinical measures or whether ... -
The effects of hydrocolloids and squash on the texture and color of scones with reduced fat
(University of Missouri--Columbia, 2012)Obesity has become a major issue in the United States due to poor food choices of individuals and limited low fat items on the market that consumers are willing to eat. By making products that are lower in fat, consumers ... -
