Analysis and Optimization Laminar Viscous Flow Through a Channel

Optimizing of laminar viscous flow through a pipe by two dimensionless values is investigated analytically. Dimensionless entropy generation and pumping power to heat transfer rate ratio are used as basis for constant viscous and the temperature dependence on the viscosity. For this matter we calculate entropy generation and pumping power for a fully developed in a pipe subjected to constant wall temperature for either constant viscosity and the variable viscosity. The variation entropy generation increase along the pipe length for viscous fluid is drawn, either the variation summation dimensionless entropy generation and the pumping power to heat transfer rate ratio are varying the fluid inlet temperature for fixed pipe length and are varying pipe length for fixed fluid inlet temperature are drawn. For low heat transfer conditions the entropy generation due to viscosity friction becomes dominant and the dependence of viscosity with the temperature becomes essentially important to be considered.     

Uptake of 226radium and 228radium by the lichen genus Umbilicaria

The 226Ra and 228Ra content of the lichens Umbilicaria cylindrica, U. deusta, U. murina and U. hirsuta has been determined as a function of the growth altitude above sea level, based on data derived from material collected from localities in southwest Poland. These data are interpreted as graphs and formulae to show the influence of environmental factors, particularly altitude, on the concentration of 226Ra and 228Ra, and the coefficients of accumulation calculated.     

攀钢转炉炼钢用碳化硅提温的试验研究

低品位碳化硅是转炉炼钢的有效提高温剂。工业性试验结果表明，碳化硅加入８．０ｋｇ／ｔ钢水提温４０．３－７０．３℃（平均４８．４℃）；渣中ＴＦｅ降低１．３％；加提温剂有利于转炉内造渣脱硫和碱少炉渣对耐火砖的侵蚀。文中还给出了攀钢转炉半钢冶炼铸用钢不水时加与不加碳化硅的ｔλ，［Ｃ］λ区域。

Award for distinguished scientific early career contributions to psychology: Robert M. Nosofsky.

The Early Career Awards, given for the first time in 1974, recognize the large number of excellent young psychologists. Recipients of this award may not have held a doctoral degree for more than nine years. For purposes of this award, psychology has been divided into 10 areas: animal learning and behavior, comparative; developmental; health; cognition/human learning; psychopathology; behavioral and cognitive neuroscience; perception/motor performance; social; applied research; and individual differences. Five areas are considered each year, with areas rotated in two-year cycles. The citation, biography, and selected bibliography of Robert M. Nosofsky, one of the 1993 recipients of the Award for Distinguished Scientific Early Career Contributions to Psychology (Cognition/Human Learning), are presented here.

"Comment on 'Articulation of values'": Response to Cochran (1988).

We respond to Cochran's critique of our 1986 study, which was in part a replication of Cochran's original grid methodology for the study of career values. (PsycINFO Database Record (c) 2010 APA, all rights reserved)
