Some theoretical issues associated with fence, prairie and plateau lizards, Sceloporus undulatus.(Brief Article)
Apr 01, 2002; Chiszar, David ... Sceloporus undulatus as currently understood is divided into 10 subspecies that are grouped into three exerges (an exerge is a group of related subspecies): undulatus, consobrinus and tristichus. The subspecies within the undulatus and tristichus exerges have well developed gular and ...
The actions of methoprene acid on a developing urodele.(Brief Article)
Apr 01, 2002; Lopez, Elena M. ... The objective of this study was to characterize the biological actions of methoprene acid (MA), a metabolite of the insecticide methoprene, on a developing axolotl, Ambystoma mexicanum, and to assess levels of developmental stability following treatment of embryos and hatchlings. We tested ...
Photo-induced absorption effects in photorefractive polymer materials.(Brief Article)
Apr 01, 2002; Christensen, Thomas M. ... Several different types of polymer thin films demonstrate photorefractive properties. Some of these materials also exhibit a change in their optical properties when exposed to laser light. We examined thin film (100-200 micron thick) Methine dye polymers, PVK/PDCST/BBP/[C.sub.60] polymer ...
Seismic loading and single plate shear connection survivability.(Brief Article)
Apr 01, 2002; Crocker, Joseph ... The challenge for building flames experiencing seismic loading is to maintain system continuity while responding to the energy demands created by the resulting ground accelerations. This research focuses on the seismic response of one family of steel connections, the single plate shear ...
Effects of steroids and dioxin (2,3,7,8-TCDD) on the developing wolffian ducts of the tiger salamander Ambystoma tigrinum.(Brief Article)
Apr 01, 2002; Vajda, Alan M. ... The present study investigated the effects of the dioxin, 2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) on steroid-dependent development of amphibian gonaducts. Sexually undifferentiated larval tiger salamanders (Ambystoma tigrinum), with immature gonads were immersed in a sub lethal solution ...
Rattlesnake responses to domesticated house mice, Mus musculus, of different strains.(Brief Article)
Apr 01, 2002; Ackermann, Gail ... Rattlesnakes were offered mice (Mus musculus) of three strains: 129/SvEv. FVB/NJ, and Athymic NU/NU. We regard the first strain as a control; these mice are representative of domesticated M. musculus in that their morphology and behaviors are more-or-less archetypical. The second strain ...
Refining the kokanee salmon model of vertebrate brain aging and Alzheimer's Disease: progress in cloning the presenilin-1 gene.(Brief Article)
Apr 01, 2002; Hobbs, Steven L. ... Over 85 point mutations in the presenilin genes, PS1 and PS2, are known to cause early onset Alzheimer's Disease with 100% penetrance. PS1 is believed to function as the "gamma secretase" that cleaves amyloid precursor protein to yield beta-Amyloid (A [beta]) peptides. Cerebral A [beta] ...
A brief history of doves and pigeons in Colorado and Wyoming.(Brief Article)
Apr 01, 2002; Ryder, Ronald A. ... Since 1820, 9 species of doves and pigeons (Columbidae) have been recorded in present-day Colorado and Wyoming. The Long Expedition in 1820 found Bandtailed Pigeons near Sedalia and Mourning Doves near Colorado Springs. Passenger Pigeons (now extinct) were never found in Colorado, but one ...
Secondary melt characteristics: evidence supporting an extraterrestrial provenance for Westwater, Utah, microspherules.(Brief Article)
Apr 01, 2002; Fandrich, J.W. ... Microspherules (MS) ranging in size from 1 [micro] m to 425 [micro] m were first discovered at Westwater, Utah, in Jan. 2000. Both magnetic metallic crystalline and nonmagnetic cryptocrystalline glass MS were separated from sediments excavated from what appears to be the bottom of a late ...
The forensic identification of pyrotechnic reaction residue particles by SEM/EDS.(scanning electron microscopy/energy dispersive spectroscopy)(Brief Article)
Apr 01, 2002; Kosanke, K.L. ... Today the most reliable method for detecting gunshot residue (GSR) is through the combined use of scanning electron microscopy (SEM) and energy dispersive spectroscopy (EDS) of the X-rays produced. In recent years, this same methodology has found increasing use in detecting and ...
