Freshman and Sophomore classes, sex groups, and age groups. We did not attempt (as Travis2 did) to discover whether the test gave satisfactory results for individuals. For in order to gauge the intelligence of individuals it is generally agreed3 that one kind of test alone is insufficient, and that a series of different tests give better results; and in the second place, tests given to classes ...
مقدمه : استعمال سیگار و مواد مخدر از جمله معضلات رایج بهداشتی محسوب می شوند. نه تنها استعمال سیگار، بلکه مواجه با دود آنها نیز عواقب زیادی را برای انسان ایجاد می نماید. در معرض دود سیگار بودن نیز خطر ابتلا به سرطان و بیماری های قلبی و عروقی را افزایش می دهد. یکی از عوامل مطرح شده در مورد مصرف سیگار اختلال در روند التیام زخم می باشد. بر همین اساس بر آن شدیم که به بررسی اثر مصرف سیگار بر روی باز ...
The filter method is a technique for solving nonlinear programming problems. The filter algorithm has two phases in each iteration. The first one reduces a measure of infeasibility, while in the second the objective function value is reduced. In real optimization problems, usually the objective function is not differentiable or its derivatives are unknown. In these cases it becomes essential to...
If you’ve ever found yourself struggling under a heavy pile of suitcases at the end of a holiday, spare a thought for the porters in some of the planet’s most remote locations. ‘When you start looking around, professional porters all around the world carry loads supported by their heads’, says Norman Heglund, from the Université catholique de Louvain, Belgium, who is fascinated by the technique...
In this work, we propose a new median-finding algorithm which computes the median value in an input list of integers on-the-fly, without any data-sorting operations. We present a complete digital CMOS implementation, associated timing diagrams, and a formal mathematical proof, which show the overall average number of clock cycles for median-finding to be linearly proportional to the input lengt...
Cholera rapid diagnostic tests (RDT) could play a central role in outbreak detection and surveillance in low-resource settings, but their modest performance has hindered their broad adoption. The addition of an enrichment step may improve test specificity. We describe the results of a prospective diagnostic evaluation of the Crystal VC RDT (Span Diagnostics, India) with enrichment step and of c...
Varian introduced (in 2010) the option of removing the flattening filter (FF) in their C-Arm linacs for intensity-modulated treatments. This mode, called flattening filter-free (FFF), offers the advantage of a greater dose rate. Varian's "Portal Dosimetry" is an electronic portal imager device (EPID)-based tool for IMRT verification. This tool lacks the capability of verifying flattening filter...
PCR is a highly sensitive method for the detection of human immunodeficiency virus type 1 (HIV-1) nucleic acids in blood mononuclear cells and plasma. However, blood separation techniques require extensive laboratory support systems and are difficult when a limited volume of blood is available, which is often the case for infants. The use of blood samples stored on filter paper has many advanta...
background: leptin plays a key role in the regulation of energy expenditure and is known to circulate in both free and bound forms. soluble leptin receptor (sob-r) is a unique circulating form of leptin receptor that can bind to leptin. leptin and leptin receptor have been implicated in processes leading to breast cancer initiation and progression. our study was aimed to investigate the relatio...
