بهداشت و درمان تاریخچه ای به قدمت عمر انسان دارد از روشهای ابتدایی مقابله با بیماریهای سالهای اولیه زندگی بشر همراه با خرافات و جادو تا دستیابی به روشهای علمی و متکی بر دانش و تجربه ای که اینک تحت عنوان پزشکی در مراکز بهداشت و درمان درمانگاهها و بیمارستانها ارائه می گردد. با توجه به افزایش روزافزون جمعیت و علل زمینه ساز بیماریها، نیاز به مراکز تشخیص و درمان روز بروز بیشتر احساس می گردد. افزایش ...
Participants switched between two randomly ordered, two-choice reaction-time (RT) tasks, where an instructional cue preceded the target stimulus and indicated which task to execute. Task-switching cost dissipated passively while the participants waited for the instructional cue in order to know which task to execute (during the Response-Cue Interval). Switching cost was sharply reduced, but not...
In order to determine the response of yield and seed yield components of red bean )Phaseolus vulgaris L. ( genotypes to delay in planting, this study was conducted in Factorial experiment based on a RCB design with 3 replications in the Jahad-Keshavarzi Research farm of Miyaneh in 2006. Factors included cultivars in three levels(Naz, Gole and Sayad) and planting date in three levels (5 and 20 ...

Analysis of the roles of the short chain fatty acid receptor, free fatty acid 3 receptor (FFA3), has been severely limited by the low potency of its endogenous ligands, the crossover of function of these on the closely related free fatty acid 2 receptor, and a dearth of FFA3-selective synthetic ligands. From a series of hexahydroquinolone-3-carboxamides, we demonstrate that 4-(furan-2-yl)-2-met...
This paper takes a doubting, though friendly, look at the hypotheses of “second generation deciine” and “segmented assimiiation” that have framed the emerging research agenda on the new second generation. We begin with a review of the basic approach, outlining the logic of argument, and specifying the central contentions.We then head toward the past, in search of material that will illuminate b...
