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 ...
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...
The goal of this study is searching effective time (before, during and after physical practice) for mental practice in learning the Volleyball Service Skill. Forty-five beginner students, aged 12–14 years, with no history of Volleyball Service Skill participated in the study (45 Male ones). Most of them were Secondary school students. All were unable to serve Volleyball correctly. The subject...
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...
Pancreatic polypeptide (PP) can be used as a marker for endocrine active tumors originating from the pancreas. After intravenous administration of secretin, individually divergent increases in plasma PP concentration can be observed hampering interpretation of the stimulation test. Under certain circumstances elevated basal PP concentrations can be observed. Besides age, renal insufficiency and...

Prevalence of Polypharmacy and Correlations with Sex, Age and Drug Regimen in Insurance Prescription
Abstract Simultaneous use of multiple drugs (Polypharmacy, PP) is associated with adverse drug reactions, medication errors, increased risk of hospitalisation and increased curative costs, specially when the number of drugs exceeds four items. This cross-sectional study was conducted to determine prevalence of PP and its some associated factors. Data were derived from health insurance prescrip...
