This dissertation investigates whether residents of Windhoek's squatter settlements are changing urban space through their efforts to secure housing and to conduct remunerative work from their dwellings. Studies about the informal economy have moved from analysis of it as a distinct sector to the social and political processes that create...
Measurements of the ratios of charged kaon decay rates for Ke3/K2pi, Kmu3/K2pi and Kmu3/Ke3 are presented. These measurements are based on charged kaon decays collected in a dedicated run in 2003 by the NA48/2 experiment at CERN. The results obtained are Ke3/K2pi = 0.2470 +- 0.0009 (stat) +- 0.0004 (syst)...
This dissertation examines the nature and development of Protestant ideology in Tudor England. Historians have traditionally seen Tudor Protestants as classic "magisterial" reformers. Unlike "radical reformers," who formed separated sects and rejected the union of church and state, English Protestants are seen as deeply committed to royal authority and the...
A number of new satiric forms -- or emergent genres -- have exploded in popularity almost simultaneously in recent years, all markedly political, all incorporating the real into the mimetic in striking ways, and all straddling the line between satire and serious political dialogue. This dissertation focuses on three of...
New telecommunication techniques utilizing distinctive quantum properties, e.g., measurement uncertainties and entanglement, extend the capabilities of existing systems. Quantum cryptography, as an example, provides physical layer security enforced by fundamental physical laws, while modern cryptographic techniques rely on assumptions of intractability of certain mathematical problems with limited computational power.
Rapid...
A catalytic, multi-component coupling reaction for the synthesis of nitrogen-containing heterocycles has been developed, via the reaction of an imine, α-diazoester and unsaturated coupling partner in the presence of a copper(I) or rhodium(II) transition metal catalyst with excellent diastereo-selectivities and high yields. The transition metal-catalyzed decomposition of a diazo compound...
The use of processes based on microorganisms to produce fuels, monomers, and pharmaceuticals from renewable feedstocks is increasing today due to their environmental and economic advantages over petrochemical-based processes. In order to unlock the full potential of microorganisms to produce a sustainable industry centered on biosynthesis, an improved understanding of...
It is critical to genomic integrity that DNA is replicated completely and faithfully during each cell cycle. The essential replication factor Cdt1 is a critical protein in preventing reinitiation of replication. Overexpression of Cdt1 causes re-replication in p53 null cells and transforms NIH3T3 cells, causing them to form tumors in...
During the sixteenth and seventeenth centuries, many images of dwarves, hirsutes, and castrati depict them in the guise of the monstrous, either as jokes of nature or indices of courtly wit. However, there are some Renaissance portraits of physically deformed individuals that transcend these categories. These portraits point to the...
As technology moves into deep submicron and nanoscale era, undesirable trends such as increasing power density, leakage power, and temperature variation within chips have made thermal effects emerge as a major bottleneck in further technology scaling. Thermal effects are no longer considered as just a reliability issue, but it also...
