Tomato is one of the sensitive fruits to mechanical impacts and physical tensions. The mostmechanical damages arise from handling which results in reducing tomato quality. in this study,impact energy effect has been studied in 3 different levels 0, 0.14 and 0.25 J by a pendulum impactapparatus, on changes of physicochemical properties of tomato, hybrid variety Shiva F1, includingripening factor...

Excessive water production through fractures become an important problem in oil exploration of fractured reservoirs. For this purpose, polymer gels were prepared by crosslinking of aqueous solutions of polymer and crosslinker for the purpose of water management in high water cut fractured reservoirs. A copolymer of sulfonated polyacrylamide was used as polymer and chromium triacetate (Cr(OA...

parathyroid hormone (pth) is the major factor of calcium homeostasis. this hormone increases calcium uptake in intestines through stimulation of the active formation of vitamin d and eventually increases bone density. the aim of this study was to investigate the effect of one session of resistance and endurance activity on pth and alp in untrained young girls (mean age 21.9±1.23 yrs, height 161...

two hundred and ninty four engorged female ticks were collected from 4 different geographical regions for assessment of tick resistance against acaricide compounds.the 15-21 day- old larvae have been tested in accordance with fao recommended larvae packet test .resistant factor for each region was calculated by lc50 and lc99. minimum lc50 (0.008)and, maximum lc50 (0.024) for amitraz were seen i...

An important risk factor for thrombosis is the polymorphism R506Q in factor V that causes resistance of factor Va to proteolytic inactivation by activated protein C (APC). To study the potential influence of the carbohydrate moieties of factor Va on its inactivation by APC, factor V was subjected to mild deglycosylation (neuraminidase plus N-glycanase) under nondenaturing conditions. The APC re...

A coagulation test abnormality, termed activated protein C (APC) resistance, involving poor anticoagulant response to APC is currently the most common laboratory finding among venous thrombophilic patients. Because the anticoagulant activity of APC involves inactivation of factors Va and Vllla, studies were made to assess the presence of abnormal factors V or VIII. Diluted aliquots of plasma fr...
