McMan A rotating solid target design concept is being developed for potential use at the second SNS target station (STS). A long pulse beam ( 1 ms) at 1.3 GeV and 20 Hz is planned with power levels at or above 1 MW. Since the long pulse may give fut...

Thermal diffusion of high polymers in a continuous medium is independent of the molecular weight Mw. Accounting for the solvent molecular structure and the Brownian motion of the solute, we derive an additional contribution of opposite sign which is significant for short chains but vanishes as Mw-->infinity. Our findings explain the dependence on Mw observed recently for polystyrene, and its in...

phosphorylatson, if any, only occurs in later stages of infection. Isolation of mitochondria (Mw) from potato tuber tissue (Solanum tuberosum L.) which are reasonably intact and show respiratory control by adenosine diphosphate (ADP) has been des cribed recently.3,4) The present paper deals with some properties of Mw prepared from healthy, infected and cut potato tuber tissues. The method of ex...

Analysis of NaCl toxicity in Chlorella sorokiniana showed decreased growth rates, increased dry weight per cell, increased intracellular Na(+) and Cl(-), more total chlorophyll per cell, a decreased chlorophyll a to chlorophyll b ratio, increased rates of O(2) evolution, and decreased rates of CO(2) fixation when the extracellular concentration of NaCl was increased from zero to 0.3 m. Cultures...

In this research seismicity parameters, repeat times and occurrence probability of large earthquakes are estimated for 35 seismic lineaments in Persian plateau and the surrounding area. 628 earthquakes of historical time and present century with MW>5.5 were used for further data analysis. A probabilistic model is used for forecasting future large earthquake occurrences in each chosen lineament....

Sediment microbial fuel cells (SMFCs) are a promising technology for a viable source of energy. This technology is faced with many challenges, such as limited mass transfer and low electricity generation. The aim of this research was to investigate the effect of electrolyte conductivity and aeration effect on power generation from SMFCs. Electrical conductivity was adjusted at 6different levels...
