Chemotactic Response of Lumbricus terrestris Coelomocytes to Larval and Adult Stages of Rhabditis pellio

Chemotactic Response of Lumbricus terrestris Coelomocytes to Larval and Adult Stages of Rhabditis pellio

Access: Use of this item is restricted to the UNT Community.
Date: December 1999
Creator: Medrano, Jennifer Centurion
Description: Experiments were performed to assess the suitability of Rhabditis pellio, a nematode found in earthworms, as a challenge organism for use in development of a biomarker assay to determine the potential of chemicals to suppress the immunocompetence of the non-specific immune system. To accomplish this goal, information on the life cycle of R. pellio was determined; including effects of incubation time and temperature on growth rates; along with information on the immune response elicited in the earthworm, Lumbricus terrestris. Immune parameters measured were coelomocyte migration toward and attachment to R. pellio larvae and adults. Preliminary background information showed that R. pellio has potential as a challenge organism for development of a biomarker assay.

Classification of toolmark surfaces on zipper teeth

Classification of toolmark surfaces on zipper teeth

Date: December 1999
Creator: Jacobsen, Dawn
Description: This study proposes the classification of the toolmark under the heads of zipper teeth as a subclass characteristic as outlined by the Association of Firearm and Toolmark Examiners (AFTE). Two separate cases in which zipper teeth were found at crime scenes prompted this study. Brass zipper teeth manufactured by YKK were taken from 20 pairs of jeans and studied using a Reichert comparison microscope at 4X power. Photographs were taken and over 750 comparisons made. It was found that the toolmarks on each side on the 20 zippers were unique and independent of all other sides. The observations made in this study indicate that classifying zipper teeth toolmarks as a subclass characteristic is valid.

Climate Change 1995: IPCC Second Assessment Report

Climate Change 1995: IPCC Second Assessment Report

Date: 1995
Creator: Intergovernmental Panel on Climate Change
Description: The Intergovernmental Panel on Climate Change (IPCC) completed its Second Assessment Report in December 1995. The major conclusions are that greenhouse gas concentrations are increasing, the global climate has been changing, and will likely continue to change, probably due to human influence.

Climate Change and Human Health, USGCRP Seminar, 10 July 1995.

Climate Change and Human Health, USGCRP Seminar, 10 July 1995.

Date: July 10, 1995
Creator: Epstein, Paul R.
Description: In this USGRP Seminar, Dr. Epstein discusses the implications of climate change and the emergence of diseases and viruses such as the hantavirus, dengue fever, ebola, cholera, malaria, and eastern equine encephalitis. These signals of global change can be costly to health, commerce, tourism, and transportation.

Climate Change: State of Knowledge

Climate Change: State of Knowledge

Date: March 1995
Creator: Environmental division, Office of Science and Technology Policy, Executive Office of the President
Description: This brief report describes that the Earth's climate is predicted to change because human activities are altering the chemical composition of the atmosphere. The buildup of greenhouse gases-primarily carbon dioxide, methane, nitrous oxide and chlorofluorocarbons-is changing the radiation balance of the planet. The basic heat-trapping property of these greenhouse gases is essentially undisputed. However, there is considerable scientific uncertainty about exactly how and when the Earth's climate will respond to enhanced greenhouse gases. The direct effects of climate change will include changes in temperature, precipitation, soil moisture, and sea level. Such changes could have adverse effects on ecological systems, human health, and socio-economic sectors.

Climate Change: The Evidence Mounts Up

Climate Change: The Evidence Mounts Up

Date: August 24, 1995
Creator: MacCracken, Michael C.
Description: This article was published in Nature and summarized the presentations of a six-day symposium held 3-8 July 1995 on Climate Variability and Forcing over the past mellennium. Our present climate is unusually warm, and the pattern of warming over the past century strongly suggests an anthropogenic influence from greenhouse gas and sulphate aerosols. That was the message emerging from a week-long symposium examining climate variability over the past 1,000 years, which brought together results from a growing array of observational techniques, analyses of natural records and model results.
