A mathematical model for syneresis of cheese curd in one dimension is presented based on the theory of mechanics of porous media. The simple mathematics leave room for surprising physical considerations and several interesting observations are made. Model parameters are estimated and validated...

Callus induced from the leaves of Eucommia ulmoides, a medicinal woody plant, was cultivated to produce a factor capable of enhancing collagen synthesis in animal cells (FECS). However, the callus was too rigid to be divided into small pieces by a hydrodynamic force during the cultivation, which...

The development of SCAM, a three-dimensional numerical model for the prediction of airflow and scalar dispersion in urban canyons, has been described [3]. The first application of SCAM [4] was to study the dispersion of carbon monoxide emanating from car exhausts, but the long term aim has been...

We study the cooling system for submersible electric pumps. This study aims to provide some guidelines to improve the existing cooling system of these electric pumps when they work partially or totally not immersed in the service fluid. Note that inefficient cooling systems cannot prevent the...

A population balance model is presented for describing the direct particle-to-particle heat transfer in fluid–solid processing systems. In developing the model, simple kinetic equations are assumed to describe the heat transfer process, but the particle–particle interactions are considered...
