The Development Of Signal Transduction Pathways During Epididymal Maturation Is Calcium Dependent, Heath W. Ecroyd, Kelly Asquith, Russell C. Jones, Robert J. Aitken

Heath Ecroyd

Capacitation has been correlated with the activation of a cAMP-PKA-dependent signaling pathway leading to protein tyrosine phosphorylation. The ability to exhibit this response to cAMP matures during epididymal maturation in concert with the ability of the sperrnatozoa to capacitate. In this study, we have addressed the mechanisms by which spermatozoa gain the potential to activate this signaling pathway during epididymal maturation. In a modified Tyrode's medium containing 1.7 mM calcium, caput spermatozoa had significantly higher [Ca2+](i) than caudal cells and could not tyrosine phosphorylate in response to cAMP. However, in calcium-depleted medium both caput and caudal cells could exhibit a …

Development Of Functional Indices Of Facility Occurrence Towards The Distribution Of Social Services In Lagos Island Nigeria., Augustus O. Atubi

Confluence Journal Environmental Studies (CJES), Kogi State University, Nigeria

Proper coordination of transport and public facilities provision is vital to any balanced regional development strategy. The central aim of this study, therefore, is to find out what the relationship is between access to the transport network and the provision of functional indices of facility occurrence towards the distribution of social services in Lagos Island, Nigeria. In particular it seeks to find out areas that have below or above average level of facility occurrences relative to the level of accessibility. However, a pair wise correlation matrix of the eleven (11) variables employed in the index construction was carried out. The …

Stakeholders' Perceptions Of Risk For Gentrification In Atlanta's Pittsburgh Neighborhood, David C. Holmes

Geosciences Theses

The 2008-2010 foreclosure crisis and the Beltline project present two significant forces shaping neighborhoods throughout Atlanta. Both the high foreclosure rates and the promise of public and private investment create conditions for the displacement of existing residents and for the gentrification of the southwest Atlanta neighborhood of Pittsburgh in particular. Through qualitative analysis, including interviews with residents, community leaders, and government officials, the development of overlay analysis maps of Pittsburgh, as well as studying the various stakeholders' perception of risk for gentrification in Pittsburgh, this research examines how and why these stakeholders' perception of the risk of gentrification in Pittsburgh …

Determining the Effects of Technology on Children

Kristina Hatch

Faculty Sponser: Timothy Henry, Computer Science and Statistics

Technology has become an essential part of Americans’ daily lives, affecting our communications, mail, relationships, the management of our bills and finances. As we have become more immersed in the benefits and capabilities of these constantly developing technologies, children as well as adults have become avid users. Laptops and cell phones are specially developed for preteens. Software and game companies have been targeting children in their game development. Video games have become common entertainment for children as young as four. Children today can …

Improving Business Performance Through Effectively Managing Employees, Ross E.L. Poquette

Academic Symposium of Undergraduate Scholarship
