table grapes (vitis vinifera l. cv. shahroodi) were stored for 45 days under modified atmospher packaging (map) with four gas combination treatments including gc1 (control or air), gc2 (10%co2+5%o2), gc3 (10%co2+15%o2) and gc4 (10%co2 + 60%o2) using two types of polymeric films pp (polypropylene) and pe (polyethylene) at 1oc and 80-90% rh. measurements were carried out after each 15 days at 1oc...

PP-g-PS copolymer is a typical compatilizer used in polypropylene and polystyrene immiscible blends. PP-g-PS copolymers with different side chain lengths were synthesized, and their thermal and mechanical properties were characterized by differential scanning calorimetry (DSC), polarizing optical microscopy (POM) and dynamic mechanical analysis (DMA), respectively. The DSC and POM results show ...

precocious pubarche (pp) is most often a benign condition secondary to the early appearance of adrenarche. however, pp may be a manifestation of mild errors of steroidogenesis in particular non classic 21 hydroxylase deficiency (nc210hd). the incidence of nc210hd in patients with pp ranges from about 0-30% of cases in various reports. controversy exists as to whether all children with pp should...

INTRODUCTION Volume overload is a main factor in development of hypertension in hemodialysis patients. In order to demonstrate impact of ultrafiltration volume on blood pressure during 15-months period in a group of patients undergoing chronic hemodialysis therapy, we conducted this study. We hypothesized that ultrafiltration volume different affects the pre/postdialysis systolic pressure, dias...

In this work, a series of polypropylene/polyvinyl butyral (PP/PVB) blends were prepared by melt-blending process, at PVB loadings 3 wt%, 10 wt%, and 30 wt%. The effects of PVB on crystallization behavior of PP were investigated by differential scanning calorimetry (DSC), and polarized optical microscopy (POM). The isothermal crystallization kinetics were analyzed by Avrami equations. It was fou...

In this study, eight binary blends of polypropylene (PP)/ poly [styrene-b-(ethylene-co butylene)-b-styrene] tri-block copolymer (SEBS) and polypropylene (PP)/ polycarbonate (PC) were produced at different composition through twin screw extruder. The composition of the minor phases was changed to correlate the morphology and mechanical properties of binary blends (PP/PC and PP/SEBS) through ther...
