Nanocomposites are unique materials with unique physical, mechanical and chemical properties that can find use in a wide range of applications. Nanocomposites are made of at least one nanosize material with polymeric systems ...
Countably Compact, Countably Tight, Non-Compact Spaces
(2011-07-28)
In this work, we will study several examples of countably compact, countably tight, non-compact spaces. After reviewing the important basic notions, we will examine a construction of several such spaces first given by Manes ...
Generalizing Clatworthy Group Divisible Designs
(2011-07-28)
Clatworthy described the eleven group divisible designs with three groups, block size four, and replication number at most 10. Each of these can be generalized in natural ways. In this dissertation neat constructions are ...
Simulations of watershed response to land use and climate change in the Saugahatchee Creek Watershed using the WARMF model
(2011-07-28)
During recent years, land surfaces have been markedly transformed with artificial land cover limiting natural forests, accompanied by urbanization. The atmospheric concentration of greenhouse gases is believed to be ...
A Study of the Impact of Changes to International Student Visa Policy and Procedures since the 9/11 Attacks
(2011-07-28)
After the 9/11 terrorist attacks, U.S. international student visa policy and procedures underwent drastic changes having an obvious and immediate impact on foreign students, higher education institutions, international ...
S(ex)pression: Sexuality and Gender Oppression in Dirty War Argentina
(2011-07-28)
The period of conflict known as the Dirty War was a pointedly sexual oppression inflicted on the people of Argentina by their fledgling militant government. For these adolescent powers that lacked political legitimacy, ...
8-Alkyl Adenines and Their Nucleoside Derivatives
(2011-07-28)
S-adenosylhomocysteine hydrolase has become an important target in the design of antiviral drugs. It is the only known enzyme in eukaryotes that is responsible for the catabolism of S-adenosylhomocysteine into adenosine ...
Characterization of the Role of dadA in Pseudomonas aeruginosa Virulence Factor Production
(2011-07-28)
Chronic Pseudomonas aeruginosa infections remain the leading cause of lung dysfunction and mortality in Cystic Fibrosis (CF) patients. Many other bacteria reside within the CF lung, but P. aeruginosa utilizes novel ...
Continuity of Parenting across Generations: The Interplay of Parenting Styles and Age at First Birth
(2011-07-28)
Using prospective longitudinal data, this study examined cross-generational linkages in positive and negative parenting and in age of becoming a parent. Of particular interest was whether early-childhood parenting and being ...
Community College Students’ Attitudes toward Postsecondary Science Education
(2011-07-28)
Students in the United States are avoiding taking the higher level science courses in secondary and postsecondary academic institutions (Ball, 2000; Braund & Reiss, 2006; Lee & Frank, 1990). There are many careers that do ...
Influence of Dietary Fat and Vitamin E on Shelf Life of Ground Broiler Breast and Thigh Meat
(2011-07-27)
A series of experiments were conducted to determine the effects of dietary fat sources and vitamin E supplementation on shelf life of ground broiler breast and thigh meat. The first experiment evaluated the influence of ...
Control of a Fuel Delivery System for Polymer Electrolyte Membrane Fuel Cells based on a Two-Phase Transient Model
(2011-07-27)
Polymer electrolyte membrane fuel cells (PEMFCs) are a type of fuel cell that converts the chemical energy released by the reaction of hydrogen (fuel) and oxygen into electrical energy and generates water and heat. The ...
