An evaluation of the utilization of remote sensing in resource and environmental management of the Chesapeake Bay region

A nine-month study was conducted to assess the effectiveness of the NASA Wallops Chesapeake Bay Ecological Program in remote sensing. The study consisted of a follow-up investigation and information analysis of actual cases in which remote sensing was utilized by management and research personnel in the Chesapeake Bay region. The study concludes that the NASA Wallops Chesapeake Bay Ecological Program is effective, both in terms of costs and performance

Rheology and ultrasonic properties of Pt57.5Ni5.3Cu14.7P22.5 liquid

The equilibrium and nonequilibrium viscosity and isoconfigurational shear modulus of Pt57.5Ni5.3Cu14.7P22.5 supercooled liquid are evaluated using continuous–strain-rate compression experiments and ultrasonic measurements. By means of a thermodynamically-consistent cooperative shear model, variations in viscosity with both temperature and strain rate are uniquely correlated to the variations in isoconfigurational shear modulus, which leads to an accurate prediction of the liquid fragility and to a good description of the liquid strain-rate sensitivity

Extending The Grazing Season Through The Use Of Cover Crops

The use of cover crops in integrated crop-livestock systems is not a novel approach but has increased in popularity over the last few years due to the renewed interest in soil conservation, nutrient cycling, and water conservation. Moreover, cool-season annual forages have the ability to extend the grazing season, reduce the need for stored or bought supplemental feedstuffs, and as a result, lower winter-feeding costs. Small grain cover crops, legumes, forbes, and annual ryegrass (Lolium multiflorum Lam.) vary in their growth distribution and can be planted alone in monocultures or planted in mixtures to take advantage of the individual growth patterns. The Southeast alone accounts for 12% of the total farmland in the United States and has major cash crops of cotton, peanuts, soybeans and corn in addition to warm-season perennial pastures that can be overseeded with cover crops. Opportunity exists for beef and row crop producers to diversify their operations and take advantage of the growing season of cover crops

Coverage of Australia by CNN World Report and US Television Network News

This content analysis contrasts CNN World Report and US television network news stories regarding Australia, using the CNN World Report Index and the Vanderbilt Television News (US networks) Archive and Index, both from 1987 to 1996. Significant differences emerged in the Australia topics chosen for presentation in these different news environments. US network stories typically were breaking news voice-overs of sports, disasters, animals, national politics, and crime. The two had similar percentages of soft news, but CNN World Report had significantly more background reporter packages on health, culture, economics, education, science, the military, and the environment
