This work develops a method of estimating peak daily streamflow, Qpeak, for Kentucky streams using daily average streamflow, Qave, data from the United States Geological Survey's (USGS) National Water Information System (NWIS) website. The purpose...
Spinal cord injury (SCI) can be divided into two distinct stages, an initial mechanical impact and a later "secondary injury" resulting from a cascade of cytokines triggering a spreading demyelination and apoptosis of neurons and glia...
Females have a higher incidence of autoimmune diseases than males for reasons that are currently unknown. CD4+CD25+ regulatory T cells play an important role in the maintenance of immunological homeostasis and self-tolerance by suppressing...
In blood coagulation, the serine protease thrombin is a multifaceted enzyme that interacts with multiple proteins. Thrombin utilizes two anion binding exosites (ABE-I and II) to supplement binding to fibrinogen and to the platelet receptor GpIbα,...
Lead Zirconate Titanate (PZT), known for its ferroelectric properties, is widely used in micro-electromechanical (MEMS) and nano-electromechanical (NEMS) devices. PZT is a ceramic material that is most commonly found in its sol gel form, which...
Employees--Training of; Call centers--Employees--Training of
In the past 35 years, the average U.S. corporation expenditure per employee on training has increased over ten-fold, yet research studies covering the same time period estimate that only 10-15% of skills and knowledge acquired during training...
Neurosphere forming cells (NSFCs) have been derived from cultures of adult olfactory neuroepithelium obtained from patients and cadavers in serum rich medium. These neural progenitors remain undifferentiated when maintained in serum rich medium but...
Rising concerns about dependency on fossil fuels in the 21st century has sparked a growth in research for renewable energy sources. One renewable energy production process of interest is the reduction of cellulose into fermentable sugars by means...
Oxygen is critical to aerobic metabolism, but hyperoxia is cytostatic and cytocidal. The precise mechanisms involved in hyperoxic cell injury remain incompletely understood although there is substantial support for the possibility that hyperoxia...
African American men--Employment; African American men--Attitudes; Mentoring in business; Job satisfaction
This dissertation is a correlational designed study that examined the strength and direction of the relationship between mentoring, job satisfaction, and organizational commitment, of African American men, exclusively in a business setting (N =...
High solids processing of biomass slurries provides the following benefits: maximized product concentration in the fermentable sugar stream, reduced water usage, and reduced reactor size. However, high solids processing poses mixing and heat...
Athletic shoes; Foot--Wounds and injuries--Prevention
The purpose of this investigation was to determine if cycling shoes made with stiff material cause an increase in peak plantar stress over shoes with less stiff material. Shoe stiffness measurements were collected under controlled conditions and in...
Heart--Diseases--Patients--Rehabilitation; Data mining
The purpose of this paper is to examine the process of text mining and using the results to show the possible benefits of cardiopulmonary rehabilitation. The 555 patients enrolled in the study were receiving inpatient cardiopulmonary...
Algebra--Study and teaching (Secondary); Motivation in education; Feedback (Psychology)
The double-blind study used two intact ninth grade high school Algebra One classes for a total sample size of 46. Within each of the classes the participants were assigned randomly to one of three treatment groups: self-referenced feedback,...
In the electronic and microfabrication industry, die separation is one of the most critical steps in producing an undamaged, stand-alone micro-scale device. For silicon based devices, it is the predominant step governing resistance to die failure...
This dissertation is concerned with investigating robust approaches for the control of pneumatic muscle systems. Pneumatic muscle is a novel type of actuator. Besides having a high ratio of power to weight and flexible control of movement, it also...
Heat pipes; Solar heating--Passive systems; Solar heating--Research; Solar energy--Research
The one dimensional heat transfer, thermal diode effect of heat pipes makes
them ideal for passive solar applications. Gains in a heat pipe passive solar wall are not
lost during cloud cover or periods of low irradiation. An experimental model was...
Nosocomial infections; Catheterization--Complications; Drug resistance in microorganisms
Catheters represent an essential part of the management of critically and chronically ill patients. However, their use is often plagued by catheter related blood stream infections (CRBSIs), which are associated with increased morbidity, hospital...
College students; College attendance; Educational attainment; Prediction of scholastic success
This dissertation explored the four-year college experience of first-generation and continuing-generation students at a small private institution. Using Astin's I-E-O model (1970), the following variables in the student experience were considered:...
Teachers--Job satisfaction--Kentucky--Louisville; Teacher turnover--Kentucky--Louisville; First year teachers--Kentucky--Louisville
This study addressed the job satisfaction of new teachers in Jefferson County Public Schools (JCPS). in Jefferson County, Kentucky. The JCPS district is the 29th largest in the United Sates and serves over 98,000 students. Understanding what...
