Nitrosomonas sp. strain AL212 is an obligate chemolithotrophic ammonia-oxidizing bacterium (AOB) that was originally isolated in 1997 by Yuichi Suwa and colleagues. This organism belongs to Nitrosomonas cluster 6A, which is characterized by sensitivity to high ammonia concentrations, higher substrate affinity (lower K[subscript m]), and lower maximum growth rates than...
Variation in data is abundant and ubiquitous in real-world applications. Managing variation in databases is, however, difficult and has been extensively studied by the database community. Schema evolution, data integration, and database versioning are examples of well-studied forms of database variation with effective context-specific solutions. However, variation appears in different...
In this thesis, I present the variational database management system, a formal framework and its implementation for representing variation in relational databases and managing variational information needs. A variational database is intended to support any kind of variation in a database. Specific kinds of variation in databases have already been...
Transgenic down-regulation of the Pt4CL1 gene family encoding 4-coumarate:coenzyme A ligase (4CL) has been reported as a
means for reducing lignin content in cell walls and increasing overall growth rates, thereby improving feedstock quality for
paper and bioethanol production. Using hybrid poplar (Populus tremula 3 Populus alba), we applied this...
This thesis examines the origins and outcomes of Operation Paperclip, a program the U.S. government operated in the years immediately following WWII to recruit former Nazi doctors, scientists, and technicians, and capitalize on their research experience. As part of this operation, the U.S. welcomed two doctors who had conducted medical...
This research project examines the growing informal sector of Ukrainian economy and the way global economic changes affect women's lives. It has been noticed by many Western researchers that women have been among the hardest hit by economic restructuring in Eastern Europe. Marginalization from the official labor force led a...
