conclusions the educational framework provided by im for at training improved attitude and behavioral beliefs that can facilitate the adoption of at behavior and decreased clbp. results significant differences were recorded before and after intervention (p < 0.001) for the model constructs of intention, perceived risk, direct attitude, behavioral beliefs, and knowledge in both groups. direct at...
dust is a common atmospheric phenomenon in iran especially in central arid regions. this severely affects environment as well as resident’s health. among the results of this phenomenon are respiratory diseases, bash radiation, accelerated soil erosion, desertification and degradation of ecosystems. some dusts are originated from local desert conditions but adjacency to neighboring countries de...
conclusions results show that trigger point injection therapy in patients suffering from chronic lumbosacral radiculopathy with trigger points can significantly improve their recovery, and conservative therapy may not be adequate. results out of 98 patients, 64 had trigger points. thirty-two patients were assigned to each group. pain scores (mean ± sd) in tp group was 7.12 ± 1.13 and in n group...
conclusions altogether, ozone had significant positive effects on patients with disk herniation unresponsive to other conservative and minimally invasive treatments. background disk herniation (dh) is one of the most common disk lesions, inducing low back pain (lbp). various therapeutic options have been proposed for treatment of disk herniation (dh). intradiscal injection of ozone has been sug...
background prematurity is an issue related to increasing the neonatal morbidity and mortality and smoking pregnant women cause the risk of low birth weight and prematurity increase, compared to non-smoking ones. results of all 205 women, 43 (20.97%) women exposed to shs during pregnancy and 162 (79.02%) women did not. in shs exposure group, 11 infant (25.6%) and in non- shs exposure group, 17 i...
in a retrospective study the clinical presentations, neurological findings, contrast studies, operative findings, and the follow-up results of 314 patients with disc herniation were studied over a 10-year period. this disease was most frequent between the ages of 30 to 40 and mostly in males. low back pain with or without radicular pain was the most frequent symptom, involving the left leg in t...
background: alterations in the neuromuscular control of the spine were found in patients with chronic low back pain (clbp). sudden loading of the spine is assumed to be the cause of approximately 12% of lower back injuries. however, some aspects of this problem, such as alterations in the sensory–motor control of the spine, remain questionable. this study investigated postural and neuro–motor c...
بویلرهای فایرتیوب به بویلرهایی گفته می شود که در آنها محصولات احتراق، درون لوله ها و آب در پوسته بویلر و پیرامون لوله ها جریان دارد. با توجه به بخش عمده مصرف انرژی در تولید بخار و آب گرم، بویلرهای فایرتیوب و کیفیت کارکرد آنها جهت مصرف کمتر سوخت و انرژی، بایستی مورد توجه قرار گیرند. بهبود جزئی در بازدهی بویلرها می تواند منجر به ذخیره سازی اساسی انرژی گردد و حتی کوچکترین تغییرات در جهت افزایش ران...
در این پایان نامه به مطالعه عددی رفتار نانوسیالات غیرنیوتنی در مدلسازی صحیح انتقال حرارت این نوع سیالات توسط نرم افزار fluent پرداخته شده است. در کارحاضر از مدل توانی ( (power low جهت تعیین رفتار غیرنیوتنی ویسکوزیته سیال پایه استفاده شده است. تنش برشی سیال غیرنیوتنی تابعی از نرخ برشی درنظرگرفته شده است. در این مطالعه به دلیل وجود اصطکاک بین ذرات نانو و سیال غیرنیوتنی از مدل دوفازی مخلوط بادرنظر...
in this work, a novel and fast method for direct analysis of volatile compounds (davc) of medicinal plants has been developed by holding a filament from different parts of a plant in the gc injection port. the extraction and analysis of volatile components of a small amount of plant were carried out in one-step without any sample preparation. after optimization of temperature, extraction time a...
