Design and code metrics have been successfully used for predicting fault-prone modules. In this dissertation, we introduce fault prediction from software requirements. Furthermore, we …

Post-Transcriptional Regulation Of Rpos And Hema In Salmonella, Amy Madeline Jones

Graduate Theses, Dissertations, and Problem Reports (ETD)

The first part of this thesis is dedicated to translational regulation of rpoS mRNA by the small noncoding RNAs (sRNAs), DsrA and RprA, in two closely related enteric bacteria, Escherichia coli, and Salmonella enterica serovar Typhimurium. The rpoS gene encodes a second vegetative sigma factor for RNA polymerase, which directs the cell's transcriptional response to general stress and entry into stationary phase. The rpoS gene is highly conserved among the gamma-branch of proteobacteria, and sRNAs are highly conserved in related species. In fact, sequence conservation is thought to have predictive value in sRNA discovery and functional conservation is largely assumed. …

Characteristics Of Subordinate Follicles Following Removal Of The Dominant Follicle: Induction Of Selection, Matthew Dean

Graduate Theses, Dissertations, and Problem Reports (ETD)

In mammals, ovarian follicles begin as primordial follicles. Over time these follicles are gradually activated and begin growth. As they proceed, granulosal and thecal cells are acquired. Eventually, the follicles become dependent on FSH for survival. Two or three times each cycle, a transient increase in FSH allows a cohort of follicles, including the follicle that will ovulate, to continue growing. However, these follicles secrete inhibin and estradiol, which suppress FSH secretion. Eventually, all the follicles of the cohort undergo atresia due to the declining concentrations of FSH, except for the follicle which has the potential to ovulate. This follicle …

Isoform- And Cell-Specific Function Of Tyrosine Decarboxylase In The Drosophila Malpighian Tubule, Edward M. Blumenthal

Biological Sciences Faculty Research and Publications

The biogenic amine tyramine (TA) is a potent diuretic factor when applied to the Malpighian tubule (MT) of Drosophila melanogaster, stimulating both urine production and transepithelial chloride conductance. Isolated MTs can respond not only to TA but also to its precursor, tyrosine; this observation led to the proposal that MTs are able to synthesize TA from applied tyrosine through the action of the enzyme tyrosine decarboxylase (TDC). In the current study it is shown that the non-neuronal isoform of TDC, Tdc1, is expressed in the principal cells of the MT. A mutant allele of Tdc1, Tdc1^{f03311 …}

Identity And Democracy: Linking Individual And Social Reasoning, John B. Davis, Solange Regina Marin

Economics Faculty Research and Publications

Following Amartya Sen's approach, John Davis and Solange Regina Marin look at individual and social reasoning when examining the complex relationship between identity and democracy. They characterize democracy as a process of social or public reasoning that combines the individual reasoning of all citizens. Identity is explained in terms of personal identity, social identity, and individual identity. They argue that democracy in combining the individual reasoning of all citizens responds to individuals’ different personal identity concerns and needs, reflects their shared social identity interests and goals, and accords them rights and responsibilities associated with their many different individual identities.

Why Egregious Errors Of Law May Yet Justify A Refusal Of Enforcement Under The 'New York Convention', Seng Wei, Edward Ti

Research Collection Yong Pung How School Of Law

Parties on the losing side in international arbitration have long argued that an error of law is a defence to the enforcement of foreign awards. Citing article V(2)(b) of the New York Convention, such parties have argued that a manifest error of law is a violation of public policy. While national courts have generally paid little heed to this line of argument, this article seeks to raise the possibility that there may yet be the exceedingly rare instance in which a court should preclude enforcing an award marred by a hideous error of law. Limited review of an arbitrator's application …
