Insufficient sleep may lead to adverse cardio-metabolic effects by influencing body weight, blood pressure, and glucose tolerance. We aimed to assess the relation between sleep duration and indices of obesity including body mass index (BMI) and waist circumference in a sample population in central Iran. We selected a sub-sample of 1770 individuals from Isfahan Healthy Heart Program. The data re...

This study assesses the reported farm income crisis in Canada and uses farm financial data to illustrate the importance and impact that management skills and practices have on farm income and net worth. For grain and oilseed farms, large farms produce higher revenues per hectare and achieve economies of scale on operating expenses, interest and depreciation, making them significantly more profi...

Information on the amount, distribution, and characteristics of coarse woody debris (CWD) in forest ecosystems is in high demand by wildlife biologists, fire specialists, and ecologists. In its important role in wildlife habitat, fuel loading, forest productivity, and carbon sequestration, CWD is an indicator of forest health. Because of this, the USDA Forest Service Pacific Northwest Research ...

Recent advances in our understanding of axon guidance during neural development are highlighted by the characterization of several gene families containing members capable of functioning as repellents. These include ephrins, netrins, and semaphorins. Though future work will undoubtedly result in the identification of still more repellents, the wealth of information now in hand concerning the ce...

Net uptake of carbon dioxide (CO2) measured by eddy covariance in a 60- to 80-year-old forest averaged 2.0 +/- 0.4 megagrams of carbon per hectare per year during 1993 to 2000, with interannual variations exceeding 50%. Biometry indicated storage of 1.6 +/- 0.4 megagrams of carbon per hectare per year over 8 years, 60% in live biomass and the balance in coarse woody debris and soils, confirming...
