In the United States, graduate programs in the biomedical sciences are designed to provide individuals with the training necessary to pursue an independent career in research. The curriculum typically involves a combination of coursework, in which students obtain depth and breadth in the subject matter of their discipline, as well as extensive practical experience plann....

There is variability in the pattern of weight change in response to a weight loss intervention (i.e., slowing of subsequent weight loss, cessation of weight loss, weight regain). A reduction in resting energy expenditure (REE) may partially explain the observed variability. Few studies have examined the effect of initial weight loss on change in REE. PURPOSE: To examine....

Observational studies of reading instruction for hearing students with and without a disability have provided valuable descriptive information on reading instruction; however, similar studies involving students who are deaf/hard of hearing have not been reported. Thus, an observational study of reading instruction, using the MS-CISSAR protocol, was conducted in general ....

Background: Disease and patient care processes often create characteristic mathematical and temporal patterns in time-stamped clinical events and observations, but existing medical record systems have a limited ability to recognize or visualize these patterns. System Design: This dissertation introduces the process-oriented approach to clinical data analysis and visuali....

Elementary, middle, and retired teachers, from the Montour School District, volunteered to participate in a research study of teachers attitudes and beliefs pertaining to academic standards and inclusion of autistic students in the general curriculum. Fourteen participants completed two surveys and a personal interview with an independent observer present. Survey respon....

The synthesis and characterization of copolymers possessing exact repeating sequences of 9,9-dihexylfluorene and methylene repeat units are described. Each poly(9,9-dihexylfluorene-mb-methylene) (PFM, mb = multiblock) was synthesized following the assembly of a symmetrically disubstituted monodisperse oligofluorene. Alkyl segments possessing terminal alkene functionalit....

Studies towards the total synthesis of the cytotoxic marine macrolide Amphidinolide B have been disclosed. Catalytic asymmetric AAC methodology has been applied to efficiently generate the C11- and the C18- stereocenters in the requisite fragments 114 and 120 throughnbeta-lactones 102 and 81 respectively. An efficient route to install the C14-C15 trisubstituted alkene w....

We are developing a systematic method for the design and synthesis of rigid macromolecular scaffolds capable of displaying chemical functionality in three dimensional space. These scaffolds will enable the study of structure-function relationships in designed receptors, and to examine factors governing biological catalysis. The scaffolds might also be used as tools for ....

Part I considers electron transport through a molecular bridge coupled to two metal electrodes in the presence of a monochromatic ac radiation field. Coherent current flow through the wire is calculated within a nondissipative one-electron tight binding model of the quantum dynamics. Using Floquet theory, the field-driven molecular wire is mapped to an effective time- i....

We developed several photonic crystal hydrogel sensors based on our Polymerized Crystalline Colloidal Array (PCCA) technology. Highly-charged colloidal particles ~ 100 nm in size self-assemble in low ionic strength solutions to form an electrostatically stabilized crystalline colloidal array (CCA). These CCA occur as face-centered cubic (fcc) lattice structures which Br....

Using a model derived from McAnanys (1995) study of ancient Mayan ancestor veneration, this study evaluated the patterns of treatment of the dead, and corresponding sociopolitical implications, at the Middle Horizon (A.D. 500-1000) site of Conchopata, a secondary center of the Wari Empire located in Ayacucho, Peru. In addition to residential zones, public plazas, cerami....
