The "early-labeled" peak (ELP) of 14CO excretion following injection of glycine-2-14C was used to study erythropoiesis in a patient with sideroblastic anemia and in four subjects with myeloproliferative disorders. The ELP was greatly enlarged in all patients, as compared with a normal volunteer. The contour of the peaks from the hematologically abnormal subjects suggested the presence of increa...

Introduction of chirped-pulse amplification (CPA) enabled the latest revolution in production of high peak powers from lasers through amplification of very short (femtosecond) laser pulses to pulse energies previously available only from long-pulse lasers. CPA has rapidly bridged the gap from its initial modest demonstrations to multi-terawatt and petawattscale systems in research facilities an...

The Hubbert-type analysis used to analyze the production history of oil is applied here to other raw materials. Many resources commonly thought of as being close to "peaking" such as lithium, helium, copper, and the rare earth elements, show no evidence of logistic behavior at any point in their production histories. Although many resources have exhibited logistic behavior in the past, many now...

Freshwater resources are fundamental for maintaining human health, agricultural production, economic activity as well as critical ecosystem functions. As populations and economies grow, new constraints on water resources are appearing, raising questions about limits to water availability. Such resource questions are not new. The specter of "peak oil"--a peaking and then decline in oil productio...

the aim of the study was to evaluate the effect of storage and temperature on egg physical quality in hyline chickens line. a total of 150 eggs from college of natural resources farm were sampled for the present experiment. about 70 eggs each were stored in home refrigerator (temperature, 7.46±0.23 ˚c; relative humidity, 24.80±0.05%) and room temperature (temperature, 22.98±1.12 ˚c; relative hu...

BACKGROUND Circulatory power (CP) and ventilatory power (VP) are indices that have been used for the clinical evaluation of patients with heart failure; however, no study has evaluated these indices in patients with coronary artery disease (CAD) without heart failure. OBJECTIVE To characterize both indices in patients with CAD compared with healthy controls. METHODS Eighty-seven men [CAD gr...
