determination of physical properties of municipal waste compost is necessary to obtain the parameters related to designing and constructing a suitable pelleting machine for producing compost pellets. the purpose of this study is determining some physical properties such as; bulk density, coefficient of friction, porosity, angle of repose for compost and density and expansion for compost pellets...
We present an implementation of realistic static friction in molecular dynamics (MD) simulations of granular particles. In our model, to break contacts between two particles, one has to apply a finite amount of force, determined by the Coulomb criterion. Using a two dimensional model, we show that piles generated by avalanches have a finite angle of repose θR (finite slopes). Furthermore, these...

Particle size and shape influence the production of solid dosage forms. This study aimed to use the three shape descriptors available in the literature to describe the shapes of six compounds, and evaluate whether angle of repose might predict the flowability of a powder sample the same as those made by compressibility index and Hausner ratio. Images of cephalexin monohydrate, niacin, nystatin,...
– We investigate the effects of lateral walls on the angle of movement and on the angle of repose of a granular pile. Our experimental results for beads immersed in water are similar to previous results obtained in air and to recent numerical simulations. All of these results, showing an increase of pile angles with a decreasing gap width, are explained by a model based on the redirection of st...
the purpose of this study was to develop a new monolithic matrix tablet to completely deliver glipizide in a zero order manner over a sustained period. two approaches were examined using drug in a formulation that contain polymer like hydroxylpropyl methyl-cellulose k 100 (hpmck) and eudragit l 100. the granules were prepared by wet granulation method and thereby formulated as f-1, f-2. f-3 and...
