This study examines buyers and nonbuyers of long-term care insurance. The findings show that consumers purchased more comprehensive products in 1994-95 than they did in 1990, and that they appeared to get better value for the premium dollar. While annual sales are increasing at a rate of 25%, the market for long-term care insurance remains small, and many of the market barriers that existed fou...

Polyether ionophores, monensin, and salinomycin are commonly used as antiparasitic drugs in broiler production and may be present in broiler litter (bird excreta plus bedding material). Long-term application of broiler litter to pastures may lead to ionophore contamination of surface waters. Because polyether ionophores break down at low pH, we hypothesized that decreasing litter pH with an aci...

The Erosion Productivity Impact Calculator (EPIC) model is validated using long-term data collected for two southwest Iowa watersheds that have been cropped in continuous corn under two different tillage systems. The annual hydrologic balance was calibrated during 1988-94 by adjusting the runoff curve numbers and residue effects on soil evaporation. Model validation was performed for 1976-87 us...

Urban expansion is a major driving force altering local and regional hydrology and increasing non-point source (NPS) pollution. To explore these environmental consequences of urbanization, land use change was forecast, and long-term runoff and NPS pollution were assessed in the Muskegon River watershed, located on the eastern coast of Lake Michigan. A land use change model, LTM, and a web-based...

Organic amendments such as composts and mulches have been shown to improve soil quality and reduce the impacts of stormwater runoff and soil erosion Previous studies using rainfall simulators have documented that runoff volumes and soil erosion can be significantly reduced when organic materials are added to the soil profile. The objectives of this study are to measure the changes in runoff and...

Understanding the basic runoff processes in the Ethiopian highlands is vital for effective management and utilization of water resources and soil conservation planning. An important question for judging effectiveness of conservation practices is whether runoff is affected by ecology (mainly type of crop) or topography (landscape). A study was conducted in the 113 ha watershed of Maybar, located...

We study the multifractal temporal scaling properties of river discharge and precipitation records. We compare the results for the multifractal detrended fluctuation analysis method with the results for the wavelet transform modulus maxima technique and obtain agreement within the error margins. In contrast to previous studies, we find non-universal behaviour: On long time scales, above a cross...

De novo protein synthesis and transcription are necessary for the expression of long-lasting synaptic potentiation [long-term potentiation (LTP)] in hippocampal area CA1 and for the consolidation of long-term memory. The stability of LTP and its longevity require macromolecular synthesis at later stages, but a specific role for early protein synthesis has not been identified. Using electrophysi...

Sleep deprivation disrupts hippocampal function and plasticity. In particular, long-term memory consolidation is impaired by sleep deprivation, suggesting that a specific critical period exists following learning during which sleep is necessary. To elucidate the impact of sleep deprivation on long-term memory consolidation and synaptic plasticity, long-term memory was assessed when mice were sl...
