Bacterial Source Tracking in the Sinking Creek Watershed Using Antibiotic Resistance Analysis and Ribotyping.
… bacterial source tracking techniques, antibiotic resistance analysis (ARA) and ribotyping, to determine the sources of bacteria isolated from Sinking Creek. Based on the results of this study, ARA and ribotyping are not useful techniques for identifying sources of fecal pollution in Sinking Creek. …

Thermal and hydraulic analysis of the adsorption bed of the adsorptive thermal battery
… is widely investigated. This work focuses on the analysis of the design of such a system to suggest efficiency improvements. The thermal insulation and choice of pump required for the optimal function of the adsorptive bed that carries the novel material are analyzed respectively to understand …

Fabrication and simulation of CMOS-compatible photodiodes
… had a higher responsivity of -0.5 A/W. Spreading resistance profiles (SRP) indicate that better control of the n-type contact is needed to systematically reproduce these results. Furthermore, spreading resistance analysis demonstrated that elimination of the p-type seed during growth will result …

Determining Sources of Fecal Contamination in Two Rivers of Northumberland County, Virginia
… Bay. Bacterial source tracking (antibiotic resistance analysis of Eschericia coli) was used to determine the sources of fecal contamination that have caused shellfish harvest closures in these two rivers. A total of 1,248 Eschericia coli isolates were collected from known sources to build a …

Identifying Sources of Fecal Pollution in Water as Function of Sampling Frequency Under Low and High Stream Flow Conditions
… were classified by source using antibiotic resistance analysis (ARA) and comparing the resulting patterns against a known-source E. coli library (1,158 isolates). The same process was performed with enterococci isolates against an enterococci library (1,182 isolates). The average rate of …

Resistance to protein synthesis inhibitors in Coprinus cinereus
… the cellular component conferring cycloheximide-resistance in two cycloheximide-resistant mutant strains, CY 8.2 and CY9.23 In both of these strains, resistance to cycloheximide was found to be associated with the cytoplasmic ribosome fraction. It was not possible to Identify the particular …

Determining Sources of Fecal Pollution in the Blackwater River Watershed, Franklin County, Virginia
Antibiotic resistance analysis (ARA) was used to determine sources of fecal pollution in the Blackwater River in South-central Virginia. The Department of Environmental Quality designated six segments as impaired due to high fecal coliform concentrations with non-point source (NPS) agriculture the …

A Comparative Study of Three Bacterial Source Tracking Methods and the Fate of Fecal Indicator Bacteria in Marine Waters and Sediments
… source tracking (MST) methods antibiotic resistance analysis (ARA), Bacteroides human-specific primer test, and fluorometry were compared against the FIBs to determine how reliable each method was in detecting the presence of human fecal contamination. Two phases (Summer 2009 and 2010) …

Determining Sources of Fecal Pollution in Water for a Rural Virginia Community
… for a rural community (Millwood, VA). Antibiotic resistance analysis (ARA) is the primary BST method for fecal source identification, followed by randomly amplified polymorphic DNA (RAPD) analysis for confirmation. Millwood consists of 66 homes, all served by individual septic systems, and a …

Determining Sources of Fecal Pollution in Washington D.C. Waterways
Antibiotic resistance analysis (ARA) of Enterococci was used to determine sources of fecal contamination in three District of Columbia waterways: Rock Creek, the Anacostia River, and the Potomac River. These three waterways were identified as exceeding water quality standards set for fecal coliform …

Landscape utilisation by an introduced pack of African wild dogs (Lycaon pictus) in eastern Botswana
… Following a thorough population viability analysis in the late 1990s the decision was taken to manage the South African population as a metapopulation. This involved the reintroduction of packs to small, fenced protected areas and the subsequent transfer of individuals or small groups …

Identifying Sources of Fecal Pollution in the Appomattox River Watershed
… within the city of Petersburg). Using Antibiotic Resistance Analysis, a known source library of 1,280 E. coli isolates (320 isolates per source) was constructed. Water samples were collected monthly for between eleven and fourteen months (11/02-12/03) from 40 locations throughout the Appomattox …

Evaluation, Development and Improvement of Genotypic, Phenotypic and Chemical Microbial Source Tracking Methods and Application to Fecal Pollution at Virginia's Public Beaches
… source tracking (MST) methods of antibiotic resistance analysis (ARA) and fluorometry (to detect optical brighteners in detergents) were used in the summers of 2004 and 2005 to determine the origins of fecal pollution at beaches with a past history of, or the potential for, high enterococci …

Analyzing Resistance to Design Chemical Inhibitors of AAA Proteins
<p>Chemotype-specific resistance is a major factor limiting the efficacy of molecularly targeted therapeutics. Analyses of resistance mechanisms to drugs reveal that mutations conferring resistance often arise in the drug's binding sites. As selective binding of inhibitors to their protein targets …

Epitaxial Ge/Il-V Heterostructures : MOCVD growth, characterization, and applications
… ion mass spectrometry (SIMS) and spreading resistance analysis (SRA), we established correlations between the initial III-V compound surface stoichiometry and the structural, optical, and electronic properties of Ge thin films deposited on GaAs and AlAs templates. We determined that the …

Use of Escherichia coli for Microbial Source Tracking in a Mixed Use Watershed in Northern Virginia
… (MST). MST was performed using antibiotic resistance analysis (ARA) and fluorometric analysis. Escherichia coli was chosen as the indicator bacterium for purposes of comparison with previous project data and because a large body of evidence supports its use in freshwater systems. This study …

Naval Architecture Analysis of Civil War Ironclad CSS VIRGINIA
… presents the results of a naval architecture analysis of the Civil War Ironclad CSS Virginia, built by the Confederate States Navy to break the Union Blockade of Hampton Roads, and which famously engaged the USS Monitor on the second day of the Battle of Hampton Roads, March 9th, 1862. The …
