Meloxicam is a poorly water soluble non steroidal anti-inflammatory drug and antipyretic agent. The aim of the present work was to investigate the effect of different types of carriers on in vitro dissolution of meloxicam. Meloxicam solid dispersions were prepared by physical mixing, co-grinding and solvent evaporation methods with polyethylene glycol (PEG) 6000. The effect of solubilization by...

ABSTRACT: The paper contains the results of the study of cavitation dispersing in “liquid-solid” system. It is known that cavitation dispersing is one of energy effective methods of “liquid-solid” interface area increasing. For evaluation of cavitation dispersing modes providing maximum interface area the model of the process was developed. The model is based on simulation of bubble collapse ne...

The global phase diagram ~i.e., vapor–liquid and fluid–solid equilibrium! of two-center Lennard-Jones ~2CLJ! model molecules of bond length L5s has been determined by computer simulation. The vapor–liquid equilibrium conditions are obtained using the Gibbs ensemble Monte Carlo method and by performing isobaric-isothermal NPT calculations at zero pressure. In the case of the solid phase, two clo...

abstract: in this study the reliability of using response surface-neural network method to predict the osmotic dehydration properties of crookneck squash has been investigated. in order to carry out this project, the osmotic solution concentration, the osmotic solution temperature and immersion time were chosen as inputs and solid gain and water loss were selected as outputs of the designed net...

Recently, feature-based solid modeling systems have been widely used in product design. However, for engineering analysis of a product model, an abstracted CAD model composed of midsurfaces is desirable for conditions in which the abstracted model does not affect analysis result seriously. To meet this requirement, a variety of solid abstraction methods such as MAT (medial axis transformation) ...

This article presents an approach for automatically generating hexahedral meshes from solid models. The mesh generating method presented in this paper involves four major steps. First, objects called Basic LOgical Bulk shapes (BLOBs) are determined from the solid model of a given part. Second, these BLOBs are used to decompose the solid model into its various sub-volumes. Third, a multiple-bloc...

Absorption of CO2 from a gas mixture containing CO2 and nitrogen by water-based CNT nanofluids in gas–liquid hollow fiber membrane contactor was modeled and solved using COMSOL Multiphysics 5.4. The model assumed partial wetting of the membrane, along with diffusion in the axial and radial directions. In addition, Brownian motion and grazing effects were both considered in the model. The main c...
