Background: Environment and its ecosystems are affected by various natural and man-made disasters. The environmental management in disasters tries to protect ecosystems, sustain development, reduce disaster risk, and adapt to or decrease the impact of climate change. This study aimed to investigate the impact of disasters on the environment and methods of reducing these effects....
Recovery is a part of disaster management cycle during which repair and reconstruction takes place, and individuals, groups, and communities retake what they have lost and ideally the risk of future incidents reduces. Life recovery is a subjective and multidimensional issue influenced by various factors, whereas valid measurable indicators in evaluating the recovery after di...

این پژوهش به اکسید اسیون متانول در محیط قلیایی می پردازد. برای این منظور ابتدا ترسیب ذرات نیکل، پلاتین و نیکل – پلاتین بر روی زیر لایه کاغذ کربنی به روش آبکاری به شیوه ی جریان مستقیم استفاده شد. در ادامه مورفولوژی پوشش های ذرات فلزی بر روی کاغذ کربنی از طریق میکروسکوپ الکترونی روبشی بررسی و مطالعه شد. سپس خواص کاتالیستی الکترودها ی حاصل در اکسیداسیون متانول با استفاده از روشهای الکتروشیمیایی هم...
After brief overview of the principles of new digital transmission schemes that use multipled block codes (MBCs), the principles of hunting-free reframing are discussed. Then, conditions to be satisfied by line coding for hunting-free reframing are investigated. I. INTRODUCTION In previous papers, new digital transmission schemes that can drastically simplify multiplexing and clock recovery hav...
