[ 1 ] - تحلیل پیامدهای گردشگری روستایی بر توسعه (مطالعه موردی کندوان)

امروزه گردشگری روستایی از بخش های مهم در فعالیت های روستایی به شمار می رود که به عنوان راهکاری در جهت توسعه نواحی روستایی محسوب می شود مقاله حاضر نیز به بررسی کارکرد گردشگری روستایی در ایجاد اشتغال ساکنین و نیز توسعه روستای کندوان در ارتفاعات سهند استان آذربایجان شرقی که در 52 کیلومتری جنوب غربی شهر تبریز است می پردازد. روش کار به صورت میدانی بوده و اطلاعات از طریق پرسشنامه و همچنین مشاهدات نگا...

[ 2 ] - Indigenous production of biosurfactant and degradation of crude oil

The present study investigated the isolation and identification of biosurfactant producing bacteria from Iranian oil wells. The biosurfactant production of bacteria isolates was evaluated and confirmed using hemolysis and emulsification tests. The biodegradation of crude oil was studied using GC and HPLC analysis. A total of 45 strains have been isolated. These strains showed less than a 40 mN ...

[ 3 ] - بررسی اثر پوشش‌های بسته‌بندی نانو نقره بر پایه دی اکسید تیتانیوم در افزایش زمان ماندگاری فیله ماهی قزل‌آلا رنگین‌کمان (Oncorhynchus mykiss)

سابقه و هدف: اخیراً نانوذرات نقره توجه فزاینده‌ای را به علت فعالیت‌های ضد میکروبی در فرآوری غذا به خود جلب کرده‌اند. در این مطالعه، فعالیت ضد میکروبی نانوذرات نقره در پوشش‌های بسته‌بندی فیله ماهی قزل‌آلا رنگین‌کمان مورد بررسی قرار گرفت. مواد و روش‌ها: 2 نمونه پوشش‌های بسته‌بندی حاوی نانو ذرات نقره پوشش دهی شده روی دی اکسید تیتانیوم تهیه شد. ابتدا با میکروسکوپ الکترونی SEM کیفیت پوشش‌های نانو 3% ...

[ 4 ] - Role of Crisis Management in Reducing Socio-Psychological Vulnerabilities after Natural Disasters (Case study: Citizens of Bam City)

Natural disasters in various forms have been identified as destructive phenomena during the life of earth planet and are also a serious threat to the inhabitants of the planet. Therefore, this issue leaded to the formation of a process called crisis management which includes activities occurring before, within and after the event to reduce the vulnerability. The country of Iran is considered as...

[ 5 ] - Development of Membrane Bioreactor to Membrane Electro-bioreactor for Advanced Treatment of Wastewater

Limited available water resources have rendered wastewater reuse an important issue to specialists in most developed countries, today. The current study works on membrane filtration for treatment of industrial wastewater. By comparing the two methods of membrane bioreactor (MBR) and hybrid membrane electro bioreactor (MEBR) processes, it finds that earlier fouling in the membrane occurs in the ...

[ 7 ] - Synthesis and Evaluation of Lipid-based Nanoparticle Containing Ginger Extract against Aspergillus Species

Introduction: Loading the active ingredients of medicinal plants in lipid nanoparticles reduces the reaction of the active substance with the surrounding environment, such as water and oxygen, and reduces the intensity of transmission or evaporation to the external environment. In this study, intended to enhance efficacy of ginger extract, encapsulation in nanoliponiosome synthesized by thin-fi...
