گل محمدی (r. damascena mill.)مهمترین گونه ای است که در تولید گلاب، عطر و اسانس، در صنعت عطرسازی و دارویی کاربرد دارد. با وجود اهمیت عطر گل محمدی، پژوهش های مولکولی و بیوشیمیایی عطر گل این گونه هنوز در مراحل ابتدایی است. در این پژوهش، ویژگی های مولکولی و فیزیولوژیکی تولید عطر در گل محمدی در آزمایش های مختلف مورد بررسی قرار گرفتند. در آزمایش اول، پژوهشی به منظور بررسی تنوع شیمیایی اسانس میان 44 ت...
در سالهای اخیر طراحی لرزه ای سازه ها تحت ارزیابی انتقادی تازه ای با تاکید بر تغییر معیار طراحی از مقاومت به عملکرد قرار گرفته است . در طول 70 سال گذشته یعنی دوره ای که محاسبات خاص طراحی لرزه ای وارد آیین نامه ها شده است به مقاومت و عملکرد بصورت دو مفهوم یکسان نگریسته می شد در حالی که در 25 سال گذشته بتدریج این دیگاه بر اساس این واقعیت که افزایش مقاومت ممکن است با عث افزایش ایمنی و یا کاهش خرابی...
The aim of this paper is to show the application of Failure Mode Effect Analysis (FMEA) for efficient and cost-effective manufacturing. Companies need better economic gains from enhanced production, but downtime affects this paradigm. Bair Dar Textile Share Company (BDTSC) is no exception. The looming section of the case company faces on average 38.69% of downtime from the total production time...
The promise of co-production to address complex sustainability challenges is compelling. Yet, co-production, the collaborative weaving research and practice, encompasses diverse aims, terminologies practices, with poor clarity over their implications. To explore this diversity, we systematically mapped differences in how 32 initiatives from 6 continents co-produce outcomes for sustainable devel...
abstract this study was carried out to compare disinfecting effects of nanosilver with other feed disinfectants on layer hen performance, immune system, gastrointestinal microflora and intestinal morphology. total of 90 layers (lsl) were divided into five groups consisting: 1-control, 2- formalin (200 ppm), 3- formaycin (200 ppm), 4- nanosilver in drinking water (7.5 ppm) and 5-nanosilver in f...

Background and aims : Technique of Failure Modes Effects and Criticality Analysis, FMECA, is a method for identifying and analyzing all potential failure modes of a system.This technique is used to prevent failures and to reduce their effects on the system . The main goal of this study was identifying and analyzing of the potential failure modes and assessing the effects of failures in the ce...
probiotics are live microbial feed supplement and can provide health benefit to the host if administered in sufficient amounts. the most predominant species that have been used as probiotic include lactobacilli and bifidobacteria. proper administration of probiotics could be efficient in the treatment of various disorders. however; their mechanism of action is poorly understood. the effects of ...
Abstract Papyrus, produced from the white pith of Cyperus papyrus L., has been used for millennia as major writing support by ancient cultures, but there was no continuous production until modern times. Therefore, had to be rediscovered. Modern Egyptian producers claim that their sheets possess ‘the same physical and chemical properties papyri’. To study if this is accurate, commercially availa...
