151A SIMPLE AND FAST METHOD FOR CONCURRENT DIFFERENTIAL STAINING AND TUNEL LABELLING OF BOVINE BLASTOCYSTS

a simple, fast and commercial method for trypsin purification from bovine pancreas

trypsin is a serine protease found in the digestive system of many vertebrates, where it hydrolyses proteins. trypsin has been used widely in various biotechnological processes. in this study trypsin was purified using two precipitation cut, 35% and 75% as saturation percent of ammonium sulfate solutions, tca precipitation (2.5% w/v), ph precipitation and finally affinity chromatography. this m...

A new safe, simple and successful vitrification method for bovine and human blastocysts.

This study examined a new method for vitrification of blastocysts that is safe, simple and easy to learn and use. Current vitrification techniques have shortcomings that include the use of dimethyl sulphoxide, one of the more toxic cryoprotectants, and minute containers that are difficult to handle and are usually open to contamination. Cell handling and loading times are very short, which allo...

A fast and simple method for modeling of oil swelling in Co2 injection

In this paper, the role of molecular diffusion in mobilization of waterflood residual oil is examined. A moving mesh method is applied to solve the moving interface problem of residual oil blobs swelling by Co2 diffusion through a blocking water phase. The results of this modeling are compared with experimental results of a 2D glass micromodel experiment. Although, the solution method is applie...

A Simple and Fast Method for Field Calibration of Triaxial Gyroscope by using Accelerometer

the innovation of a statistical model to estimate dependable rainfall (dr) and develop it for determination and classification of drought and wet years of iran

آب حاصل از بارش منبع تأمین نیازهای بی شمار جانداران به ویژه انسان است و هرگونه کاهش در کم و کیف آن مستقیماً حیات موجودات زنده را تحت تأثیر منفی قرار می دهد. نوسان سال به سال بارش از ویژگی های اساسی و بسیار مهم بارش های سالانه ایران محسوب می شود که آثار زیان بار آن در تمام عرصه های اقتصادی، اجتماعی و حتی سیاسی- امنیتی به نحوی منعکس می شود. چون میزان آب ناشی از بارش یکی از مولفه های اصلی برنامه ...
