قدرت تفکیک دستگاه طیف‌نگار جرمی به صورت مستقیم شدت یون خروجی و انرژی آن بستگی دارد. مقدار تولید شده جریان باریکه الکترونی وابسته است. از جمله وظایف مدار کنترل چشمه برخورد تنظیم برای رسیدن بهینه می‌باشد. در ساخت پارامترهایی نظیر تثبیت آن، دقیق پتانسل الکتریکی لنز الکترودهای یونی بسیار حایز اهمیت این مقاله با قابلیت انتشار الکترون، پتانسیل نقاط طراحی ساخته شد. کنترلر بر روی طیف نگار 44Varian MAT ...

The aim of this study was to investigate the effects of Sodiume alginate edible coating with concentrations of 0/25, 1/25, 0/75 and 1/75% (W/V) on chemical changes of dressed Kilka during frozen storage. Prepared samples of Kilka fish have been coated for 1 h with the dipping method. Coated and uncoated samples have been packed in polyethylene dishes with selphon coverage (75 packs of 250 g). C...

background: edible films and coatings have potential benefits for food packaging, particularly meat products. these coatings prevent weight loss and texture changes during shelf life by reducing moisture loss in fresh and frozen meat products. in this study, effect of calcium alginate edible coating on microbial and chemical properties of refrigerated lamb meat over a period of  5 days was inve...

* Corresponding author ABSTRACT Traditional workflow models have obvious shortcomings in describing complex workflows. Such complexity is due not only to the hierarchical property of business process, but also to the complicated dependencies among tasks. In this paper, we first introduce a conceptual task model based on UML class graph. Then we apply colored Petri nets to model task interfaces ...

This research evaluated the use fenugreek seed flour (3,6,9 and 12%)as antioxidant and antimicrobial agent in manufacture of beef burgers instead of soybean flour (SF). with emphasis on frozen storage stability for most important quality criteria of beef burger. The incorporation of fenugreek seed flour into beef burger patties instead of soybean flour improving the content of essential amino a...
