Hydrological consequences of two native shrubs in semi-arid Senegal : patterns, processes, concepts and methods

Creator:: Kizito, Fred
Abstract:: Water availability is a critical limiting element in semi-arid ecosystem productivity and presents particular challenges in Sahelian countries such as Senegal. The landscapes are characterized by the presence of two common semi-arid shrubs (Piliostigma reticulatum and Guiera senegalensis), both of which may be important hydraulic regulators in these water-limited ecosystems....

The knowledge base and instructional practices of two highly qualified experienced secondary mathematics teachers

Creator:: Beauchman, Molly Laverne Taylor
Abstract:: The purpose of this study was to investigate the knowledge base and instructional practices of two highly qualified experienced secondary mathematics teachers within the context of their classrooms during a unit in a geometry class. Data collected from interviews, classroom observations, pre and post-observation questionnaires, and detailed analyses of several...

A descriptive study of demographic characteristics and perceptions of the educational preparation, professional experience, and selected duties of Christian College physical education faculty members

Creator:: Hoeck, Donald E.
Abstract:: The purpose of this study was to develop a profile of Christian College physical education faculty members regarding their academic preparation, professional experience, and selected duties, as well as to identify important components of graduate preparation at the doctoral level for future faculty at these institutions. A survey instrument was...

Evolution of aposematic warning coloration in parasitic wasps (Hymenoptera:Braconidae)

Creator:: Leathers, Jason Wayne
Abstract:: Many Hymenoptera, with their painful stings and noxious chemical defenses, exhibit bright aposematic warning color patterns and are the most frequently mimicked group of organisms. Such aposematic color patterns are found in parasitic wasps of the Neotropical Compsobracon group (Braconidae). Many members of this group exhibit color patterns similar to...

Elevated ceramide levels contribute to the age-associated decline in vascular endothelial nitric oxide : pharmacologic administration of lipoic acid partially restores function

Creator:: Smith, Anthony R.
Abstract:: The vascular endothelium is a single cell layer that lines the lumen of the entire vasculature. It is the site of synthesis of nitric oxide (NO), a vasodilatory compound synthesized by endothelial nitric oxide synthase (eNOS). NO causes intracellular calcium sequestration of the vascular smooth muscle cells, relaxing and dilating...

Potential influences of oral contraceptive use and physical activity on bone health : a one-year prospective study in young women

Creator:: Almstedt Shoepe, Hawley Chase
Abstract:: Osteoporosis is a skeletal disease affecting 44 million Americans. A primary strategy to prevent osteoporosis is to develop a high peak bone mass in youth. Oral Contraceptives (OCs) alter hormones in women and could affect bone mass development. The interaction between OCs and skeletal mineralization is poorly understood. PURPOSE: Our...

A new trigonal huntite material and subgroup relationships between crystallographic space groups

Creator:: Hruschka, Michael Archimedes and Hruschka, Michael A.
Abstract:: The use of an adjacency matrix to determine distant (not maximal or minimal) subgroup and supergroup relationships between crystallographic spacegroup types is described. Full lists of space-group types that are supergroups and subgroups for every space-group type were compiled. A list of the space-group types connected to each space-group type...

Hydrodynamic effects of particle chaining in liquid-solid magnetofluidized beds : theory, experiment, and simulation

Creator:: Cruz-Fierro, Carlos Francisco
Abstract:: In a fluidized bed of magnetically susceptible particles, the presence of a magnetic field induce the formation of particle chains due to interparticle magnetic forces. The resulting effect is a change in the overall spatial distribution of the particles, transitioning from a random, isotropic distribution to an ordered, anisotropic distribution....

Organization of the T4 dNTP synthetase complex at DNA replication sites

Creator:: Kim, JuHyun
Abstract:: With respect to a multienzyme complex of deoxyribonucleoside triphosphate (dNTP) synthesis somehow juxtaposed with DNA replication sites, our laboratory has demonstrated the existence of a multienzyme complex in T4-infected E. coli, named the T4 dNTP synthetase complex, but the idea of direct linkage of dNTP synthesis to DNA replication and...

Sequence dependent conformational variations in DNA holliday junctions

Creator:: Hays, Franklin A.
Abstract:: Four-stranded DNA junctions (also known as Holliday junctions) are structural intermediates involved in a growing number of biological processes including DNA repair, genetic recombination, and viral integration. Although previous studies have focused on understanding the conformational variability and sequence-dependent formation of Holliday junctions in solution there have been relatively few...
