BACKGROUND Bioartificial liver support system (BALSS) based on culturing hepatocytes is an important research field for the treatment of acute liver failure. It is necessary to monitor the state of liver cell functions during the treatment of BALSS in order to guide clinical treatment. OBJECTIVE To design a micro-channel chip to achieve flash mixing for timely detection of liver cell status i...

This paper presents a model that describes how liquid flow fills micro-fluidic components and networks. As an alternative to computational fluid dynamic (CFD) simulations, we use a constrained energy minimization approach. This approach is based on two assumptions that hold in many micro-fluidic devices: (i) The length scales are small, and we consider slow filling rates, hence fluid momentum a...

abstract:the general perception of islamic finance is that it prohibits the practice of paying and receiving interest, but islamicfinance is much broader than interest rate prohibition. islamic financial services can be viewed as a set of financialservices which are diversified based on the needs of society.since in the iranian economy most of the enterprises are micro and/or small, micro finan...

a micro-channel heat exchanger reactor with different micro-baffle shapes has been studied numerically. governing equations were solved base on the finite volume method with fluent software. in upper section, oxidation reaction of methanol was occurred and in lower section, steam reforming of methanol was done. two sections were separated with solid part which played as heat exchanger and trans...

Stainless steels have good corrosion resistance in many environments but welding or aging can decrease their resistance. This work focused on the effect of aging time and ultrasonic nano-crystal surface modification on the passivation behavior of 316L stainless steel. In the case of slightly sensitized 316L stainless steel, increasing the aging time drastically decreased the pitting potential, ...

Abstract We model how investors allocate between asset managers, managers choose portfolios of multiple securities, fees are set, and security prices determined. Investors indifferent higher-cost informed lower-cost uninformed interpreted as passive their portfolio is linked to the " expected market portfolio." make precise Samuelson's dictum by showing that active reduce micro-inefficiencies m...
