This study analyzes the nonlinear nature of gravel bed elevation data series obtained in a large scale flume facility for four different discharges, including spatial transect series and temporal series at a fixed location. The goals are to infer the degree of complexity, to assess the scales and features in the signals that mostly contribute to this complexity, and to discern the difference in...

BACKGROUND AND PURPOSE Treatment of hip fracture patients is controversial. We implemented a new operative and supervision algorithm (the Hvidovre algorithm) for surgical treatment of all hip fractures, primarily based on own previously published results. METHODS 2,000 consecutive patients over 50 years of age who were admitted and operated on because of a hip fracture were prospectively incl...

The diuretic effect of the supine position was evaluated in six patients with cirrhosis and ascites and six with congestive cardiac failure. After fasting overnight in bed the patients received bumetanide 1 mg intravenously and were then immediately randomly assigned to either bed rest in the supine position or normal daily activity in the upright position for the next six hours. Two days later...

BACKGROUND Chronic sleep debt is becoming increasingly common and affects millions of people in more-developed countries. Sleep debt is currently believed to have no adverse effect on health. We investigated the effect of sleep debt on metabolic and endocrine functions. METHODS We assessed carbohydrate metabolism, thyrotropic function, activity of the hypothalamo-pituitary-adrenal axis, and s...

under favorable soil conditions such as existence of easily destructible organic compounds, balanced heat and moisture, adequate ventilation and abundant nutrients, organic materials are mineralized. once mineralizing occurs, mineral elements like p, s, ca, mg, k and other cations are released. a related study was conducted to determine the effect of seven organic fertilizers (leaf mold (lm), r...

anaerobic treatment methods are more suitable for the treatment of concentrated wastewater streams, offer lower operating costs, the production of usable biogas product. the aim of this study was to investigate the performance of an anaerobic fluidized bed reactor (afbr)-aerobic moving bed bio reactor (mbbr) in series arrangement to treat currant wastewater.the bed materials of afbr were cylind...
