Electroencephalographic studies have shown two qualitatively different and alternat ing kinds of sleep, the orthodox (“slowwave―, or “¿ fore-brain―) and the paradoxical (“hind brain―, “¿ rapid eye movement―, “¿ activated―, or ...

The years 1895 to 1898 were momentous for their impact on health and human well beings. First, Wilhelm Roentgen noted a glowing fluorescent screen, caused by invisible rays. This event subsequently led to the discovery of X-rays in 1895, and thus the birth of the “atomic age”.

        This paper proposes a new forecasting model for investigating relationship between the price of crude oil, as an important energy source and GDP of the US, as the largest oil consumer, and the UK, as the oil producer. GMDH neural network and MLFF neural network approaches, which are both non-linear models, are employed to forecast GDP responses to the oil price changes. The resul...

Data defining the isolated effect of insulin on whole body protein and glucose metabolism in cancer patients are limited. Ten normal volun teers (controls), age 55 ±3 years (mean ±SEM); 8 cancer patients, age 61 ±3years, weight loss 2 ±1% (CANWL); and 8 cancer patients, age 55 ±2 years, weight loss 18 ±2% (CAWL), were studied in the postabsorptive state. Whole body leucine kinetics were d...
