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...

Diseases. By Otto May, M.A., M.D., M.R.C.P. Pp. 240. London : Oxford Medical Publications. 1918. Price 7s. 6d. net. During this time of national appreciation of the urgency of the prevention and treatment of venereal diseases Otto May's book appears opportunely. It presents the case fairly and in judicious language, and should be of service to anyone who is working in an attempt to combat vener...

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...

The aim of the present work is to enhance the antifouling properties of polypropylene (PP) membrane based on hydrophilicity improvement. Different contents of neat and modified nanodiamond (0.25, 0.50, 0.75 and 1.00 wt.%) were embedded into PP membranes. Nanodiamond nanoparticles were carboxylated by heat treatment method and the presence of carboxyl functional groups on the surface of nanopart...
