Proteins are the essence of life processes. DNA contains the coded information for life, and is analogous to computer software, but it is the proteins that are analogous to the hardware, that actually carry out the job. Proteins have many roles, from catalysts (enzymes), through proteins that bind and interact with other molecules to control their behaviour, to structural and storage proteins w...

Particle separation is of great interest in many biological and biomedical applications. Flow-based methods have been used to sort particles and cells. However, the main challenge with flow based particle separation systems is the need for a sheath flow for successful operation. Existence of the sheath liquid dilutes the analyte, necessitates precise flow control between sample and sheath flow,...

Fluorine-containing polymers have a number of valuable physical and chemical properties, such as high chemical and heat resistance, high mechanical strength and highly selective gas separation characteristics. One of the ways to produce fluoropolymer membranes is through surface fluorination. The modifcation of commercial polymers with membrane properties, poly(4-methyl-1...

The behavior of the classic algorithm for blind source separation (BSS) is detailed for a fixed step size. To improve the algorithm in speed and exactness, essential in tracking a time-varying mixing environment, a variable step size must be employed. The ideal step size should decrease or increase as the overall system error decreases or increases. It is shown analytically that the coefficient...

Liposomes are widely used as drug delivery systems in different forms including osmotic pumps, infusion and IV injection. In spite of these, there is no data available about their behavior under convective flow (e.g. infusion or osmotic pumps) and upon stagnation in such drug delivery systems. As a part of a series of investigations in this area, the present study investigates the effects of vi...

doogh- the popular iranian drink- is a product of lactic fermentation of milk and its dry matter standardized by dilution of yoghurt (following fermentation) or milk (prior to fermentation). one of the basic problems occurring during its storage is serum separation. optimum consistency accompanied by no separation of serum during storage are two desirable characteristics looked for. high methox...

The aim of this work theoretical study is to theoretically investigate a inorganic membrane assisted purifcation process of an H2-rich stream derived from a conventional methanol steam reforming stage. In particular, a black-box model for multicomponent gas mixture purifcation is dev...

This study aims to investigate and optimize the effects of the main parameters including the particle size, gravity and magnetic separation combination, high gradient magnetic separation, magnetic field intensity, shaking table slope, washing water flow, and electrostatic separation upon the rare earth element (REE) recoveries from iron mine waste. The electron microprobe showed that high amoun...
