MORHARDT, J* EMIL, AND SYLVIA S. MORHARDT. C’orrelation bafween heart rate and oxygen consumption in rodents. Am. J. Phvsiol. 221(6): 15804586. I97 1 .-Heart rates (fh , transmitted by surgically impLanted radiotelemetry transmitters) and oxygen consumption (VOW) were measured simultaneousIy from a series of rodents. Large ranges of fh and ~OZ were obtained by allowing spontaneous activity and ...

Measuring the global cerebral metabolic rate of oxygen (CMRO(2)) is a valuable tool for assessing brain vitality and function. Measurement of blood oxygen saturation (HbO(2)) and flow in the major cerebral outflow and inflow vessels can provide a global estimate of CMRO(2). We demonstrate a rapid noninvasive method for quantifying CMRO(2) by simultaneously measuring venous oxygen saturation in ...

We present the design and evaluation of two forms of power management schemes that reduce the energy consumption of networks. The first is based on adapting the rate of network operation to the offered workload, reducing the energy consumed when actively processing packets. The second is based on putting network components to sleep during idle times, reducing energy consumed in the absence of p...

faba bean is one of the proper crops for cultivation in guilan climate conditions in rotation with rice. one of the limiting factors in development of cultivating this plant is late maturity and synchronizing of its ripening with rice transplanting. to investigate the effect of planting date, timing and consumption rate of paraquat herbicide on the ripening, grain yield and some of the agronomi...
