The Steel Jaw Leghold Trap: Issues and Concerns

Description: Steel jaw leghold traps are used in 47 States in the United States to capture furbearing animals (Florida and Rhode Island have prohibited use except with special permit for nuisance animals, and New Jersey has banned all uses). In addition to use by the fur industry, these traps are employed by State agencies in game management (e.g., to control predators and diseases). The leghold trap issue pits animal welfare groups opposed to the pain and suffering of trapped animals against supporters of … more

Trapping of hydrogen in Hf-based high κ dielectric thin films for advanced CMOS applications.

Description: In recent years, advanced high κ gate dielectrics are under serious consideration to replace SiO2 and SiON in semiconductor industry. Hafnium-based dielectrics such as hafnium oxides, oxynitrides and Hf-based silicates/nitrided silicates are emerging as some of the most promising alternatives to SiO2/SiON gate dielectrics in complementary metal oxide semiconductor (CMOS) devices. Extensive efforts have been taken to understand the effects of hydrogen impurities in semiconductors and its behavi… more

Evaluation of a Common Carp (Cyprinus carpio L.) Exclusion and Trapping Device for Use in Aquatic Plant Founder Colony Establishment

Description: The focus of this study was to design and evaluate a trapping system that would reduce populations of common carp within water bodies in conjunction with establishment of native aquatic macrophytes founder colonies. A pond study and field study were conducted. A pond study was performed at the Lewisville Aquatic Ecosystem Research Facility, located in Lewisville, Texas, followed by a field study within a constructed wetland located in southern Dallas, Texas. For the pond study, twelve funne… more

Economic Value of North American Skunks

Description: "Among fur animals [the skunk] is second in importance in the United States, the muskrat alone exceeding it in total value of fur produced. Skunk are kept and reared easily in captivity, and under intelligent management may become a source of profit, although thus far those who have made money in raising them have sold the animals chiefly for breeding purposes. Further experiment will be required to decide whether they can be made profitable as fur producers in captivity.... This bulletin discu… more

Trapping Moles and Utilizing Their Skins with Especial Reference to the Pacific Coast States

Description: "Farmers' boys and others who may wish to trap moles will find in this bulletin information regarding the best kinds of traps, with directions where and how to set them, and how to prepare the skins. Moleskins may be sold to local furriers, or, if these skins are not handled by them, information regarding prices and methods of shipment may be obtained from furs houses that do business by mail.... The methods of trapping moles discussed in this bulletin are especially adapted to the Pacific Coas… more

A Kinetic-fluid Model

Description: A nonlinear kinetic-fluid model for high-beta plasmas with multiple ion species which can be applied to multiscale phenomena is presented. The model embeds important kinetic effects due to finite ion Larmor radius (FLR), wave-particle resonances, magnetic particle trapping, etc. in the framework of simple fluid descriptions. When further restricting to low frequency phenomena with frequencies less than the ion cyclotron frequency the kinetic-fluid model takes a simpler form in which the fluid e… more

Small bipolarons in boron carbides: Pair breaking in semiclassical hopping

Description: A pair of charge carriers can be bound within a common potential well produced by displacing atoms from their carrier-free equilibrium positions. These two self-trapped carriers together with the associated atomic-displacement pattern is referred to as a bipolaron. If the self-trapped carriers` wavefunction is primarily confined to a single structural unit (atom, bond or molecule), the bipolaron is termed small. If however the self-trapped carriers` wavefunction extends over multiple structural… more

Deep electronic levels in high-pressure Bridgman Cd{sub 1-x}Zn{sub x}Te

Description: The behavior of deep electronic levels was studied as a function of Zn concentration in CdZnTe crystals grown by the high-pressure Bridgman technique using thermoelectric effect spectroscopy. A significant increase of the thermal ionization energies of hole traps was observed with the increasing Zn content of the ternary compound. The effect explains the stronger hole trapping and the resulting much shorter hole lifetime usually observed in CdZnTe as compared to CdTe. The behavior also suggests… more
