Test of English as a foreign language (TOEFL) : good indicator for student success at Community Colleges?

Creator:: Ng, Jacob N. K.
Abstract:: Community colleges in the United States have become an important educational destination for international students. According to the Institute of International Education (IIE, 2006), international students who enrolled for the first time at a U.S. campus increased by 8 per cent, from 131,946 students in 2004/2005 to 142,923 in 2005/2006....

Chunking professional-technical programs to create pathways to degree completion in community colleges

Creator:: Dins, Kate
Abstract:: The purpose of this study was to explore the phenomenon of community colleges creating pathways to degree completion in professional-technical programs by breaking degree programs into smaller portions, referred to as "chunks." The purpose or possible advantage of chunking was that it would improve the rate of degree completion among...

Alternative orchard floor management practices, soil quality, nitrogen fertilizeruptake, and apple tree growth and yield

Creator:: McDonald, Sarah Finger
Abstract:: Orchard floor management (OFM) practices can improve soil function and alter the soil biological community. Soil function is dependent on soil forming materials and on management practices but little is known about how OFM affect orchard soil quality, fertilizer N uptake, or tree growth and production. Research plots were located...

A comparative study of lowpass continuous-time delta-sigma modulators with pulse-shaped DACs

Creator:: Fang, Jie
Abstract:: Recently, continuous-time ΔΣ modulators are appearing increasingly often in both the literature and the marketplace due to their features of inherent antialiasing and relaxed requirements for opamp and so on. However, several nonideal factors such as clock jitter, excess loop delay, inter-symbol interference and so on, degrade the SNR performance...

Analysis of the prevalence of type 2 diabetes in Mexicans and Mexican Americans

Creator:: Sobolik, Julia Silva
Abstract:: Non-insulin dependent diabetes mellitus (NIDDM), commonly known as type 2 or delayed onset diabetes, is a recognized growing global epidemic, which is connected to cultural and behavioral factors, such as diet, exercise, obesity, and genetics. In a recent survey of both men and women in Mexico City, the prevalence of...

Oxidative desulfurization of dibenzothiophene with tert-butyl hydro peroxide in a photochemical micro-reactor

Creator:: Hebert, Eilleen M.
Abstract:: Sulfur content in fuels is an increasingly critical environmental issue. Hydrodesulfurization removes sulfur from hydrocarbons; however, further desulfurization is necessary in fuels. New methods are required. In this study, micro-scaled single phase oxidative desulfurization is explored. An ultraviolet light-assisted micro-reactor is introduced for desulfurization of dibenzothiophene. Dibenzothiophene is mixed with...

A survey on continuous-time modulators : theory, designs and implementations

Creator:: Gao, Xiaoran
Abstract:: Recently, delta-sigma modulation has become a widely applied technique for high-performance analog-to-digital conversion of narrow-band signals. Most of the early designs used discrete-time structure for good accuracy and good linearity. The transfer functions are independent of the clock frequency. However, high unity-gain bandwidths of the opamps are required to satisfy...

Using an indicator model to rank relative stock status of minor West Coast rockfish species

Creator:: Miller, Stacey D.
Abstract:: Quantitative assessments of many West coast rockfish stocks of both major and minor importance to commercial fisheries have shown varying declines in abundances. The population sizes of less-abundant, co-occurring unassessed species may also be declining. However, determining stock status of the many non-targeted, minor species with high levels of certainty...

Gas-phase fragmentation chemistry of protonated peptide ions

Creator:: Bythell, Benjamin James
Abstract:: The fragmentation characteristics of protonated peptides have been investigated using tandem mass spectrometry (MS/MS) under various fragmentation regimes and detailed density functional theory (DFT) reaction pathway calculations. The DFT calculations predict novel salt-bridge stabilized transition structures as well as consecutive reactions occurring in proton-bound dimers for some of the ions...

Basic Concepts to Develop a Marine Pollution Monitoring Program at the Tijuana-Ensenada Corridor, Baja California, Mexico

Creator:: Alvarez-Vazquez, Hector
Abstract:: The development of a Marine Pollution Monitoring Program (MPMP), in any coastal area of the world, requires a precise knowledge of the functioning of the local ecosystem. Because of the differences found in every coastal ecosystem, it is important to recognize and characterize the reservoirs and significant environments that maintain...
