The present research has aimed to compare the competencies in teaching math using an IT-based approach in student-teachers and trainees admitted based on Article 28. A quasi-experimental approach was used, and static groups were devised, with the research sample consisting of 20 student-teachers and 20 Article 28 trainees from the province of Eastern Azerbaijan during 2018-2019. Both groups wer...
سرطان بیماری، مهلکی است که بعد از بیماری های قلبی و عروقی دومین عامل مرگ و میر در جهان می باشد. سرطان پستان یکی از شایع ترین سرطان های شناخته شده و علت اصلی ناشی ازمرگ و میر سرطان در زنان می باشد. عوامل ژنتیکی و محیطی بسیاری در ابتلا به این بیماری اثر دارد. یکی از مهم ترین عوامل خطر ساز محیطی، سیگار کشیدن می باشد که نیکوتین موجود در سیگار، با اتصال به گیرنده استیل کولین نیکوتین باعث تحریک تقسیم...
Dementia with Lewy bodies (DLB) is a common subtype of dementia in the elderly. DLB is neuropathologically characterized by the presence of Lewy bodies and Lewy neurites, both of which are composed of α-synuclein. Although α-synuclein was initially considered to be an exclusively intracellular protein, it has been found to be secreted into biological fluids. α-Synuclein in biological fluids suc...
Endotoxin [lipopolysaccharide (LPS)] causes tumor necrosis factor-α (TNF-α)-mediated myocardial contractile depression. Tolerance to the cardiac toxicity of LPS can be induced by a prior exposure to LPS or by pretreatment with glucocorticoids. The mechanisms by which the myocardium acquires tolerance to LPS remain unknown. LPS causes phosphorylation and degradation of inhibitory κB-α (IκB-α), r...
In this paper, the product of two α-k-μ random variables is analyzed. The closed form expressions for average level crossing rate (LCR) of product of two α-k-μ random variables are determined. These expressions are used for calculation of average level crossing rate of wireless communication systems operating over α-k-μ multipath fading channels. The α-k-μ distribution can be used to describe s...
