در این تحقیق سنتز آزمایشگاهی کربن فعال به روش فیزیکی در راکتور دوار با استفاده از گازهای اکسید کننده دی اکسید کربن و بخار آ ب از پوست سخت پسته به عنوان ماده اولیه مورد بررسی قرار گرفت اثر سه پارامتر دمای فعالسازی،زمان ماندودبی گاز اکسید کننده بر روی عددیدی و burn-offبا استفاده از طراحی آزمایش به روش ccd مورد بررسی قرار گرفت. این پارامتر ها دردو سطح بالا وپایین که به ترتیب برای دمای فعالسازی،زما...
Little has been reported on the effects of repeated prescribed burning southern United States’ forest soils, especially when site preparation is not fire objective. This study was aimed at identifying any correlations between soil chemical properties among differing burn intervals and them. Sampling performed in 36 plots three sites with two different (2–3 years biannually) measured properties:...
BACKGROUND The alarming incidence of self- burning provoked to set up a multidisciplinary preventive program to decrease the incidence and complications of this harmful issue. This study investigated the incidence and the preventive measures in self-burn in Fars Province, southern Iran. METHODS This study was a longitudinal prospective design on trend of self-inflicted burn injuries in Fars pro...
background and objectives: klebsiella pneumoniae is an opportunistic pathogen responsible for up to 10% of nosocomial infections. the emergence and spread of multidrug resistant k. pneumoniae , mostly due to the production of extended-spec- trum β-lactamases (esbl) and carbapenemases, is often responsible for antibiotic treatment failure of these infections. we compared the antibiotic resistanc...
عدم خاموشی راکتور به دنبال هر رخداد عملیاتی پیش بینی شده، منجر به حالت گذرای بدون خاموشی (atws) می شود که میتواند خسارت های جدی به سوخت وارد کند. به همین منظور برای خاموش سازی راکتور در زمان حادثه به یک سیستم حفاظتی با قابلیت اطمینان بالا نیاز است. مهمترین عامل در دسترس نبودن سیستم حفاظتی راکتور (rps) عملکرد ناموفق میله های کنترل برای وارد شدن به قلب در زمان حادثه می باشد. برای مثال در برخی م...
BACKGROUND Main contributors to adverse outcomes in severely burned pediatric patients are profound and complex metabolic changes in response to the initial injury. It is currently unknown how long these conditions persist beyond the acute phase post-injury. The aim of the present study was to examine the persistence of abnormalities of various clinical parameters commonly utilized to assess th...
background: telemedicine has been used in different fields of medicine in the past 20 years. the main advantages of this technology include saving costs, improving quality of care, and increasing access to specialists. this study aimed to review telemedicine applications in treating burn patients. methods: in this systematized review study, related papers were searched using various databases...
BACKGROUND Chromogranin A (CgA) in plasma (P-CgA), a neuroendocrine marker of sympathetic stress, has been shown to predict mortality in medical intensive care. We hypothesized that the magnitude of CgA release would reflect stress load, and thereby injury severity in burn intensive care patients. METHODS Fifty-one consecutive patients with a burn area exceeding 10% were included. P-CgA was m...
Although the attention for functional outcomes after burn injury has grown over the past decades, little is known about functional independence in performing activities of daily living in children after burn injury. Therefore, in this prospective cohort study functional independence was measured by burn care professionals with the WeeFIM(®) instrument in 119 pediatric patients with burns (age: ...
BACKGROUND Abnormal scar development following burn injury can cause substantial physical and psychological distress to children and their families. Common burn scar prevention and management techniques include silicone therapy, pressure garment therapy, or a combination of both. Currently, no definitive, high-quality evidence is available for the effectiveness of topical silicone gel or pressu...
