Early Christian Sex Change. The Ascetical Context Of "Being Made Male" In Early Christianity, Jennifer Lynne Henery

Dissertations (1934 -)

This dissertation shows that in the second and third century Christian stories containing transformational imagery of being made male, the vision of the eschaton motivates individuals to lives of enkrateia and martyrdom. Individuals who choose encratic lives or the life of martyrdom become holy and are described in imagery reflective of the eschaton. The eschatological vision in these texts is the product of Biblical tradition and Second Temple Judaism; visions of the eschaton explain the future state as a return to prelapsarian Eden, as participation in the heavenly temple, and as victory in the eschatological battle. This vision is the …

This projected increasing rate of solid waste generation is expected …

Socio-Economic Studies Of Scavengers In Malaysian Landfills, A.H. Zahariman, F.B. Mustafa, F. Shahul Hamid

Research Publications (2011 to 2015)

Accelerating pace of urbanization has resulted with increasing generation of municipal solid waste (MSW). Approximately 90% of these wastes are sent to landfills without any material recovery process. As a result, it creates opportunity for scavenger to retrieve valuable materials from the waste stream. This is observed in most landfill in Malaysia where scavengers collect the recyclables as their source of income. This paper examines the socio-economic of scavengers and describes the management of scavenging activity in three landfill types namely Jeram Sanitary Landfill, Bukit Beruntung Open Dump and Dengkil non-sanitary Landfill, in Selangor, Malaysia. Jeram Sanitary Landfill and Dengkil …

An Lcms Based Assay For Detection And Quantification Of Bacterial Cell Wall Intermediates, Chandra Sekhar Arigapudi

All Capstone Projects

The main objective of my project is to determine the bacterial cell wall intermediates in E.coli and develop an LCMS method that Phosphomycin is a PEP analogue that irreversibly inhibits UDP-GluNAc-enolpyruvate transferase (MurA enzyme), which prevents the formation of N-acetyl muramic acid, which is an essential element in the Peptidoglycan cell wall. Antibacterial agents have a tremendous impact on human health. Most of the antibacterial agents, including beta lactams target the bacterial cell wall biosynthesis.The pathway for Escherichia coli is shown in page 19. Among the most widely used antibiotics, beta lactams inhibit the penicillin binding protein (PBPs)which block the …

Evaluation And In Vitro Studies Of Folate Peg Biotin And Other Peg Agents, Vikram Reddy Kasarala

All Capstone Projects

Folate is an essential component for cell growth and cell division, playing a major role in DNA synthesis. It is common sense that the rapidly dividing cells synthesize more DNA, including cancer cells. Also, it was reported that cancer cells over express Folate receptors and this was the basis for our probe for cancer cells. We used long PEG biotin in conjugation with Folate. Previous studies in our group showed that the PEG could be used in the sensor to detect and capture cancer cells. The present study was aimed at evaluating the effect of Long PEG containing Folate based …

Evaluation And In Vitro Studies Of Folate Peg Biotin And Other Peg Agents, Christopher E. Zmudka

All Capstone Projects

Folate receptor alpha is a membrane-bound protein displaying high affinity for folic acid. This receptor is believed to serve as a receptor-mediated transport system of folic acid into cancer and cells associated with inflammation. Interesting, most normal cells in the body have little if no high affinity folate receptor alpha. Based on these attributes, folate based drug delivery, imaging systems, and diagnostic systems are in several stages of development worldwide.

Numerous methods have been explored in the literature in an attempt to detect low levels of free folate receptor and/or rare circulating cancer cells. In an attempt to further exploit …

Nanoparticles For Mercury Abatement, Sunil Krishna Thanikanti

All Capstone Projects

Mercury is considered to be a global contaminant. It does not break down in the environment and can build up in living organisms. Mercury can be carried long distances on wind currents, staying in the atmosphere for long periods of time, when in its vapor form. High mercury exposure results in permanent nervous system and kidney damage. Mercury exists in three different chemical forms: elemental, inorganic, and organic. The routes of exposure can be inhalation, ingestion, or skin contact. Vapor from liquid elemental mercury and methyl mercury are more easily absorbed than inorganic mercury salts and can, therefore, cause more …

Wound Healing And The Role Of Biomarkers And Biofilms, Mujtaba Khan

All Capstone Projects

An injury to the skin alters the integrity of underlying tissues and microcirculation and thus certainly culminates in a wound. Wound healing is a highly complex, dynamic, interactive and well regulated physiological process involving blood cells, extracellular matrix, parenchyma cells and soluble mediators. It starts with alteration in integrity of tissues and ends with the formation of scar. The process of wound healing is distinguished into Haemostasis, Inflammation, Proliferation and Remodeling. Various cells like platelets, neutrophils, macrophages, lymphocytes, angiocytes, keratinocytes, fibroblasts and factors like platelet derived growth factor, transforming growth factor, platelet derived epidermal growth factors, fibroblasts growth factor, albumin, …

Beyond Absurdity: Climate Regulation And The Case For Restricting The Absurd Results Doctrine, Katherine Kirklin O'Brien

Washington Law Review

The absurd results doctrine of statutory interpretation allows courts to depart from clear legislative text when a literal reading would be “absurd.” Traditionally, courts defined an absurd result as one that offends fundamental social values. Over time, however, courts have expanded the concept of legal absurdity to include outcomes that do not violate moral principles, but instead present regulatory burdens deemed too onerous to reflect congressional intent. In June 2010, the U.S. Environmental Protection Agency (EPA) invoked this expansive reading of the absurd results doctrine to support a regulation known as the “Tailoring Rule,” which the agency promulgated as part …
