Melt spinning of polypropylene nonwoven nanofiber mats is demonstrated using Forcespinning The effects of rotational speed and melt flow rate of polymer on fiber diameter were studied. It was observed that melt flow rate of the polymer plays a major role in nanofiber formation and uniformity. Differential scanning calorimetry and X-Ray Diffraction analysis indicate that the crystallinity of nan...

light-weight and high strength alloys such as al-mg alloys are used in order to reduce the weight of industrial components. however these materials should be formed at elevated temperatures due to their poor formability at room temperature. hot metal gas forming is one of the high-tech forming processes that is used to solve this problem. recent investigation on tube hydroforming showed positiv...

This study aims to determine Marshall's characteristics using asphalt binder modified polymer AC 50/70 (Starbit E-55) local Bantak material. The test method used is a hot mix (Hot Mix) with the Marshall method. content was 5% successively; 5.5%; 6%; 6.5%; and 7% consisting of 3 specimens for each variant. research carried out at Material Laboratory Department Civil Engineering Planning, Faculty...

We present simulation results from a version of the Regional OceanModeling Systemmodified for ice shelf/ocean interaction, including the parameterisation of basal melting bymolecular diffusion alone. Simulations investigate the differences in melting for an idealised ice shelf experiencing a range of cold to hot ocean cavity conditions. Both the pattern of melt and the location of maximummelt s...

During the developmental process, there is an estimated 40 to 70% incidence of delay or failure for new drug entities due to poor biopharmaceutical properties such as poor solubility, poor permeability and poor chemical stability. Hot melt extrusion (HME) technology may provide the answer. HME, a solid-dispersion technology, has gained popularity in the pharmaceutical industry as a means of imp...
