When concepts act concretely: Exploring the notion of conceptual concreteness in a novel mathematical domain
(2010-04-12)
The information we seek to communicate to learners is often conveyed by symbols, and the symbols we choose may directly affect cognition independently of the instructional strategies that we apply. The current series of ...
The product and process of heme degradation in Staphylococcus aureus
(2010-04-12)
Staphylococcus aureus is an important human pathogen and its ability to cause disease is absolutely dependent on iron acquisition from the host. S. aureus obtains iron during infection from vertebrate hemoglobin via the ...
Culture, nation and imperialism: ISEB and U.S. cultural influence in cold-war Brazil and Joaquim Nabuco, British abolitionists and the case of Morro Velho
(2010-04-16)
1. This study provides an analysis of attempts by the Instituto Superior de Estudos Brasileiros (ISEB – Higher Institute of Brazilian Studies) to interpret and/or defend Brazilian culture as written by Nelson Werneck ...
Kinetic Determinants of GABA-A Receptor Function
(2010-04-16)
GABA-A receptors are ligand-gated chloride channels that mediate the majority of fast inhibitory signaling in the central nervous system. Their kinetic properties determine the charge transfer and timing of inhibitory ...

JIA ZHANG
Dissertation under the direction of Professor Maureen A. Gannon
Both type I and type II diabetes are due to an either absolute ...
Automatic generation of boundary conditions using demons non-rigid image registration for use in 3D modality-independent elastography.
(2010-04-16)
Modality-independent elastography (MIE) is a method of elastography that reconstructs the elastic properties of tissue using images acquired under different loading conditions and a biomechanical model. Boundary conditions ...
Building power beyond the local scale: An examination of interorganizational collaboration among faith-based community organizing groups
(2010-04-16)
Faith-based community organizing groups (FBCOs) have a well-established record of engaging citizens on issues of local concern. These groups increasingly recognize the need to engage with political structures beyond the ...

This dissertation consists of three studies concerning intragenerational and intergenerational inequalities in the Social Security Program caused by different mortality rates across age cohorts and racial groups. The first ...
Comparison and assessment of semiautomatic image segmentation in computed tomography scans of the kidney.
(2010-04-16)
Segmentation, or delineation of the boundaries of a region of interest, is an integral part of implementing intraoperative image guidance for kidney tumor resection. Results are affected by the kidney's physiology and ...
Radiation-hardened-by-design (RHBD) delay locked loops (DLLS): single event transient analysis, simulation, and hardening
(2010-04-16)
Single-event transients (SETs) due to terrestrial or space radiation exposure have become a growing concern in modern high-speed data acquisition systems and space deployed electronics. Therefore the single-event vulnerability ...
