Spontaneous Mesenchymal to Epithelial Like Tissue Transition (MET) in a Long Term Human Skin Culture
In an attempt to isolate multipotent stem cells from foreskin in a long-term culture, we encountered an interesting phenomenon which was the conversion of the fibroblast dominant condition to epithelial-like tissue formation. However, the basic mechanism(s) which may be involved in this conversion is not clear. This study was designed to evaluate the cells protein secretion activity and examine...

عامل های فرآیندی بسیاری بر چگونگی عملکرد نانوفیبر سلولز به عنوان یک تقویت‌کنندۀ سلولزی دوست‌دار محیط زیست تأثیرگذارند. یکی از عامل های بالقوه تأثیرگذار، دمای اختلاط سوسپانسیون خمیر با نانوفیبر سلولز بوده که در این تحقیق به آن پرداخته شده است. به منظور بررسی تأثیر این مشخصه شتاب آبگیری اختلاط به دست آمده و ویژگی های مقاومتی کاغذ نهایی تولیدشده مورد آزمون و بررسی ...
this paper addresses the problem of minimizing the sum of maximum earliness and tardiness on identical parallel machines scheduling problem. each job has a processing time and a due date. since this problem is trying to minimize and diminish the values of earliness and tardiness, the results can be useful for just–in-time production systems. it is shown that the problem is np-hard. using effici...
