در این تحقیق به منظور اندازه گیری ارتعاش وارده، در دو موقعیت کف کابین و روی صندلی تراکتور، مقادیر rms شتاب در جهت محور عمودی (z) به وسیله دستگاه شتابسنجtv300اندازه گیری گردید. آزمایشات با یک دستگاه تراکتور مسی فرگوسن285 برای حالت های حرکت تراکتور در مسیرآسفالت بدون حمل ادوات، حرکت در مسیرآسفالت با ادوات (گاوآهن 3خیش)، حرکت در مسیر خاکی بدون ادوات، حرکت در مسیر خاکی با ادوات (گاوآهن 3خیش)، خاکور...
Metropolitan areas are governed by a patchwork of governmental units that contribute to the dispersion of people and the diffusion of local power. These effects are visible in nearly every metropolitan region whether they are growing or shrinking. The policy debate has focused on questions of efficiency, rather than the developmental impacts of these choices. Analysis must be structured to capt...
The author investigated the conditions under which a congruent or incongruent orientation word affects processing of the orientation of visual objects. Participants named the orientation of a rectangle that partially occluded another rectangle. Congruent or incongruent orientation words appeared in the relevant object, in the irrelevant object, or in the background. There were two main results....
cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
یکی از سیستم هایی که برای افزایش راندمان کاری تراکتورها طراحی و ساخته شده است سیستم قفل دیفرانسیل است. این سیستم باعث یکسان شدن دور دو محور چرخ میشود. در نتیجه در زمان رویارویی با شرایط زمینگیرایی غیریک نواخت در زیر لاستیک ها بسیار مفید خواهد بود. استفاده از این سیستم باعث بهبود زمینگیرایی، کاهش فرسایش لاستیک چرخ های محرک، کاهش مصرف سوخت و افزایش ظرفیت مزرعهای تراکتور خواهد شد. علی رغم این...
Iodine is an essential micronutrient for humans and is 1 required in a very small amount i.e. 150μg per day. The only role of iodine in the body, known at present, is for the synthesis of thyroid hormones. The human body contains 15 to 20mg of iodine of which almost 80% is in the thyroid gland. According to World Health Organization (WHO), iodine deficiency is still a public health problem in 5...
We studied the xanthine derivative propentofylline (HWA 285) to determine its protection against ischemic brain damage when administered before and after ischemia. Transient forebrain ischemia was produced in 81 Mongolian gerbils by occluding both carotid arteries. The necessary surgery was performed under anesthesia with intraperitoneal pentobarbital/chloral hydrate 2 days before occlusion. We...
Aberrant signaling of ErbB family members human epidermal growth factor 2 (HER2) and epidermal growth factor receptor (EGFR) is implicated in many human cancers, and HER2 expression is predictive of human disease recurrence and prognosis. Small molecule kinase inhibitors of EGFR and of both HER2 and EGFR have received approval for the treatment of cancer. We present the first high resolution cr...
The small conductance calcium-activated K+ channel gene SKCa3/KCNN3 maps to 1q21, a region strongly linked to schizophrenia. Recently, a 4-base pair deletion in SKCa3 was reported in a patient with schizophrenia, which truncates the protein at the end of the N-terminal cytoplasmic region (SKCa3Delta). We generated a green fluorescent protein-SKCa3 N-terminal construct (SKCa3-1/285) that is iden...
OBJECTIVE To determine how frequently Connecticut primary care physicians are diagnosing and treating patients with chronic Lyme disease. STUDY DESIGN A survey was mailed to a random 33% sample of primary care physicians in Connecticut, which asked how many cases of Lyme disease and chronic Lyme disease they diagnosed and treated in the last 3 years. RESULTS The survey had a response rate o...
