Corn kernel shape is an important feature to improve the accuracy of simulation results, also repose angle often used calibrate model parameters in simulation. In this study, effects corn shapes on behavior during kernels accumulation were investigated detail. Firstly, DEM models three typical developed. Secondly, influences process for forming investigated, such as distance change, energy conv...

Starch is a carbohydrate that can be used as binder in pharmaceutical preparations. Paracetamol has poor flowability and compactibility with its crystalline form, it necessary to make granules by wet granulation method starch binder. This study banana peel waste (Musa paradisiaca) source of starch. Three granule formulations (F1, F2, F3) were prepared using the concentrations 5% (F1), 8% (F2), ...

The present study was conducted to formulate controlled release dosage forms containing Ibuprofen with Eudragit® S 100 polymer. The tablets were formulated at three different ratios with the polymer to investigate the effect of different concentrations of polymer on in vitro drug release patterns/kinetics and in vivo absorption/pharmacokinetics. Pre-formulation studies were conducted including ...

A series of placebo powders for inhalation was characterized regarding bulk density and powder flowability using different techniques. The powders were of the ordered mixture type and were prepared by mixing a pharmaceutical carrier grade of lactose with different fractions of intermediate sized and fine (i.e., micronized) lactose. A modified Hausner Ratio was obtained by measurement of the pou...

The thermal deformation problem is quite serious for the workbench of environmental dry hobbing machine due to accumulation hot chips. A better understanding quantity and optimization chip repose angle necessary reduce deformation. Hence, this paper focuses on modeling machine. Firstly, dynamic flow characteristics chips are clarified by analyzing generation mechanism motion trajectory hobbing....

Two varieties of Pearl millet seeds (Penisetum glaucum) (Ex-Borno and SOSAT C88) were obtained from the Lake Chad Research Institute, Maiduguri-Nigeria and reconditioned to moisture contents ranging from 10% 20% w.b. The reconditioned seeds were then evaluated for dimensions, sphericity, bulk density, solid density, porosity, thousand seed mass, angle of repose and static coefficient of frictio...
