Soon after the atomic theory was established, it was found that the plant uses as sources of food not only the air and water, but also different constituents of the soil, dissolved in the soil moisture—the mineral nutrients. Ashes of different...
The purpose of this dissertation was to demonstrate that a new method of direct intracellular energy delivery was effective in maintaining viability of in vitro Human Umbilical Vein Endothelial Cells (HUVECs) when exposed to chemical ischemia for...
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...
Copper--Physiological effect; Copper in the body; Heart--Hypertrophy
Previous studies have shown that copper (Cu) supplementation at physiologically relevant levels reverses cardiac myocyte hypertrophy induced by phenylephrine (PE), and that this effect was VEGF-dependent. Yet, the amount of VEGF in the media was...
Medical appointments and schedules; Simulation methods
Healthy for Life is a relatively new University of Louisville medical clinic which attempts to stem the epidemic of childhood obesity. This program offers a range of face-to-face services for overweight children. The main problem addressed by this...
Drug resistance in microorganisms; Salmonella typhimurium
Salmonella enterica serovar Typhimurium is an enteric pathogen capable of infecting
a wide range of hosts. The manner in which this pathogen is able to interact with its
host is difficult to define, as is the case with most microbes. Through the...
Youth--Employment; Teenagers--Health and hygiene; Industrial safety; Safety education, Industrial
Teenaged workers are twice as likely to be injured on the job as adult workers, and face a
number of differences developmentally and psychosocially that present challenges for
their safety at work. Little research has focused on the tasks that...
Long-term exposure to harmful carcinogens like benzo[a]pyrene (BaP) are linked to lung cancer. Benzo[a]pyrene diol epoxide (BPDE), the ultimate carcinogen produced by BaP bioactivation, is believed to play an important role in lung carcinogenesis....
Hepatitis C virus--Research; Interferon--Therapeutic use; Adenosylmethionine
Hepatitis C virus (HCV) infection is a major cause of chronic liver disease in the United States and is a huge burden on the US healthcare system. The FDA-approved traditional standard of care for HCV is pegylated interferon-alpha (lFNα) combined...
Several technical and economic obstacles currently hamper the industrial development of ethanol from biomass. One of the key bottlenecks is the slow kinetics of the enzymatic hydrolysis of cellulose, and the subsequent rate reduction as the...
Computer-assisted instruction--Planning; Universities and colleges--Technological innovations; Distance education
This study focused on the development and validation of a web-based survey instrument designed to measure faculty perceptions on the importance of 24 variables that contribute to the facilitation of online postsecondary course development. It...
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...
Community college students--Kentucky; Transfer students--Kentucky; Academic achievement--Kentucky; College attendance; University of Louisville; Jefferson Community and Technical College
More students now begin their postsecondary education at the two-year college level with the intention of transferring to earn a bachelor's degree, making the transfer function more important. Recent government mandates in Kentucky brought about...
Barbershops--Social aspects; African American men--Social life and customs; African American men--Conduct of life; African American men--Psychology
Labeled as a man's environment, the Black barbershop is a sacred location for
Black men. Yet, it is unclear how Black men communicate in the Black barbershop.
This research study examined the communicative process of Black men within the...
Unrepaired DNA damage poses a serious threat to the genetic stability of a replicating cell. One mechanism of tolerating this damage is translesion DNA synthesis (TLS), in which an accessory polymerase synthesizes DNA directly across from a damaged...
Sleep disorders in children; Children--Sleep; Blind children
Research has confirmed that individuals with blindness have an increased risk of
developing sleep problems; this is especially problematic for families with young
children who are blind. Not only does the lack of sleep impact the growth...
O -linked β-N-acetylglucosamine ( O -GlcNAc) is an inducible, dynamically cycling, and reversible post-translational modification of serine/threonine amino acid residues of nucleocytoplasmic and mitochondrial proteins. O -GlcNAc transferase (OGT)...
Welfare recipients--United States; College students--United States
Using Schlossberg's transition theory as the conceptual framework, this case study explored and identified the coping strategies used by seven welfare recipients attending postsecondary institutions. Three participants were enrolled in the local...
Vehicles--Environmental aspects; Traffic flow--Environmental aspects; Motor vehicles--Motors--Exhaust gas
The purpose of this dissertation is to develop a methodology to estimate the temporal Environmental Traffic Capacity (ETC) for urban streets. The approach constitutes the main procedure of ETC calculation and an experimental process of developing...
Previous research on organizational mergers has found that such a business activity bears an effect upon the structural and cultural foundations of organizations. Whether combining intellectual resources or capital, mergers combine workforces that...
