A Simulation Model For Triclosan Concentrations In The North And Middle Rivers, Virginia, Preeyaporn Songkiatisak Dec 2009

A Simulation Model For Triclosan Concentrations In The North And Middle Rivers, Virginia, Preeyaporn Songkiatisak

Masters Theses, 2010-2019

Incidences of fish kills and intersex phenomena have occurred extensively in the Shenandoah River since 2004. Pharmaceuticals including triclosan have been detected at low concentrations in the Shenandoah River. Scientists hypothesize that triclosan, an antibacterial agent, may be one of the pharmaceuticals that is responsible for fish kills and intersex phenomena. Methyl triclosan (MTS) were found in fish tissues at a significantly higher concentration in the part of the Shenandoah River where fish kills are present compared to a non-impact river. Triclosan is widely used in personal care products, such as soaps, shampoos, and toothpastes and is rinsed down the …


Scoping Study Of The Effects Of Aging On Landmines, Daniele Ressler Jun 2009

Scoping Study Of The Effects Of Aging On Landmines, Daniele Ressler

CISR Studies and Reports

The Mine Action Information Center at James Madison University has partnered with a British EOD consultancy company, C King Associates Ltd, to conduct a preliminary study into the effects of aging on landmines. This project entailed examination and disassembly of several types of anti-personnel mines, a literature review of relevant material and analysis of the initial findings.

The study confirms a fairly obvious assumption: The characteristics of mines change significantly as they grow older. However, while this situation is constantly observed in the field through the recovery of rotted, rusted and damaged mines, it has never been adequately investigated. The …

Oral History Interview With William Mcgee, Philip L. Frana

Philip L Frana

William McGee is a retired senior programmer at the IBM Santa Teresa Laboratory. McGee received the AB degree in physics from the University of California at Berkeley in 1949, and the MA degree in physics from Columbia University in 1951. From 1951 to 1959, McGee managed the numerical analysis unit at the General Electric Hanford Atomic Products Operation in Richland, Washington. Between 1959 and 1964 he led systems programming and research at Ramo Wooldridge Corporation in Canoga Park, California. McGee joined ...

Don Chamberlin is a research staff member at IBM Almaden Research Center in San Jose, California. In this oral history Chamberlin recounts his early life, his education at Harvey Mudd College and Stanford University, and his work on relational database technology. Chamberlin was a member of the System R research team and, with Ray Boyce, developed the SQL database language. Chamberlin also briefly discusses his more recent research on XML query languages.


Oral History Interview With Glenn Henry, Philip L. Frana Aug 2001

Oral History Interview With Glenn Henry, Philip L. Frana

Philip L Frana

Glenn Henry begins by briefly outlining his education and early work career prior to joining IBM. The majority of the interview focuses on Henry's work as a software systems engineer and manager at IBM in the 1970s. Henry was centrally involved in the software development and hardware definitions for IBM's early Midrange Series computers. He had managerial roles at IBM San Jose and IBM Boca Raton before leading a large team at the home of IBM Midrange Series hardware and software development, IBM Rochester. He details the ...

Proposal For A Dod Combined Battlefield Electromagnetic Environmental Effects (E3) Initiative, George H. Baker Iii Oct 1993

Proposal For A Dod Combined Battlefield Electromagnetic Environmental Effects (E3) Initiative, George H. Baker Iii

Department of Integrated Science and Technology - Faculty Scholarship

The presentation emphasizes the growing importance of electromagnetic survivability and compatibility. Operation Desert Storm demonstrated the clear military advantage provided by sophisticated electronic weapon and communication systems. In addition, the offensive tactic of taking out the enemy's eyes and ears during the air war paid off, giving our military decisive air superiority. The lessons for the future are clear. High-tech electronics now so dominates the battlefield that the outcome of future conflicts could well be decided by electronics attrition rather than human casualties. Our Desert Storm experience thus accentuates the importance of guaranteeing that our electronic systems will not be …

Damage Analysis Modified Trac Computer Program (Damtrac), George H. Baker Iii, Alan D. Mcnutt, G. Bradford Shea, David M. Rubenstein May 1975

Damage Analysis Modified Trac Computer Program (Damtrac), George H. Baker Iii, Alan D. Mcnutt, G. Bradford Shea, David M. Rubenstein

Department of Integrated Science and Technology - Faculty Scholarship

A computer program tailored for EMP damage analysis of solid-state circuitry has been developed by modifying the existing TRAC network analysis program. Modification of the TRAC diode and transistor models to include breakdown parameters and the addition of a semiconductor device parameter library have greatly simplified the analyst's task. An added feature is a subroutine that automatically calculates the amplitude and duration of transient power dissipated in electronic circuit components.
