The Micro pump is an essential component in a Micro Total Analysis System (μTAS). A feasible and reliable design of the micro pump is a key for the development of the μTAS. The Valve-less Rectification Micro Pump (VRMP) has many advantages, such as: non-moving parts, independent of fluids and channels properties, reliable, and easy to fabricate. Fluid diodicity is an essential parameter of the ...

Soil is known to be heterogeneous for different activities at several spatial scales. Most studies have focused on macro- and meso-scales but micro-scales are rarely addressed. Hence, the spatial structure of NH(4)(+)- and NO(2)(-)-oxidizers and of various serotypes of the latter was studied along two transects of approximately 10 cm, with two micro-samples taken from each millimeter. The prese...

The term Micro Air Vehicles (MAVs) is used for a new type of remotely controlled, semi-autonomous or autonomous aircraft that is significantly smaller than conventional aircrafts. To apply Micro Electro Mechanical Systems (MEMS) inertial sensors for the Guidance, Navigation and Control (GNC) of Micro Air Vehicle (MAV) is an extremely challenging area. The major components of the control system ...

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...
