Contamination Levels Of Selected Organochlorine And Organophosphate Pesticides In The Selangor River, Malaysia Between 2002 To 2003, Kok Hoong Leong Jan 2007

Contamination Levels Of Selected Organochlorine And Organophosphate Pesticides In The Selangor River, Malaysia Between 2002 To 2003, Kok Hoong Leong

Kok Hoong Leong

In Malaysia, rivers are the main source of public water supplies. This study was conducted from 2002 to 2003 to determine the levels of selected organochlorine and organophosphate pesticides in the Selangor River in Malaysia. Surface water samples have been collected seasonally from nine sites along the river. A liquid–liquid extraction followed by gas chromatography–mass spectrometry technique was used to determine the trace levels of these pesticide residues. The organochlorine pesticides detected were lindane, heptachlor, endosulfan, dieldrin, endosulfan sulfate, o,p′-DDT, p,p′-DDT, o,p′-DDE and p,p′-DDE whereas for organophosphate pesticides, they were chlorpyrifos and diazinon. At the river upstream where a dam …


Why Manage Terminology? Ten Quick Answers, Uwe Muegge Jan 2007

Why Manage Terminology? Ten Quick Answers, Uwe Muegge

Uwe Muegge

Terminology management is a hot topic these days. At the tcworld conference 2006, terminology had its own forum with hundreds of participants. And a number of highly visible institutions like the LISA Terminology Special Interest Group (SIG) has been evangelizing the development and use of standardized terminology in the business world for many years.


Disciplining Words: What You Always Wanted To Know About Terminology Management, Uwe Muegge Jan 2007

Disciplining Words: What You Always Wanted To Know About Terminology Management, Uwe Muegge

Uwe Muegge

Terminology management enables organizations of any size to use the same terms consistently within and across the communication types that accompany a product or service. Typical communication types include specifications, drawings, GUI, software strings, help systems, technical documentation, marketing materials, regulatory submissions, etc. As multiple authors typically contribute to these communications, terminology management is the most efficient solution for ensuring that the organization speaks with one voice.

Laser Capture Sampling And Analytical Issues In Proteomics, Howard Gutstein, Jeffrey S. Morris Jan 2007

Laser Capture Sampling And Analytical Issues In Proteomics, Howard Gutstein, Jeffrey S. Morris

Jeffrey S. Morris

Proteomics holds the promise of evaluating global changes in protein expression and post-translational modificaiton in response to environmental stimuli. However, difficulties in achieving cellular anatomic resolution and extracting specific types of proteins from cells have limited the efficacy of these techniques. Laser capture microdissection has provided a solution to the problem of anatomical resolution in tissues. New extraction methodologies have expanded the range of proteins identified in subsequent analyses. This review will examine the application of laser capture microdissection to proteomic tissue sampling, and subsequent extraction of these samples for differential expression analysis. Statistical and other quantitative issues important for …
