Multiple state-of-the-art techniques, such as multi-dimensional micro-imaging, fast multi-channel micro-spetrophotometry, and dynamic micro-imaging analysis, were used to dynamically investigate various effects of cell under the 900 MHz electromagnetic radiation. Cell changes in shape, size under different power density electromagnetic waves radiation were presented in this paper. Experimental ...

Radio Frequency coil development, one component of a functioning magnetic resonance imaging (MRI) system, has evolved since the beginning of MRI into a very diverse area. Today for example, transmit and receive coils, volume and surface coils, and single channel and multiple channel coils are all included. Coils are created to fit the particular needs of specific research purposes, taking into ...

Title of Dissertation: STUDY OF CONDENSATION OF REFRIGERANTS IN MICRO-CHANNELS FOR DEVELOPMENT OF FUTURE COMPACT MICRO-CHANNEL CONDENSERS Sourav Chowdhury, Doctor of Philosophy, 2008 Directed By: Professor Michael Ohadi, Department of Mechanical Engineering Miniand microchannel technology has gained considerable ground in the recent years in industry and is favored due to its several advantages...

This study examines the single-phase and two-phase cooling performance of a hybrid micro-channel/micro-jet impingement cooling scheme using HFE 7100 as working fluid. This scheme consists of supplying coolant from a series of jets that deposit liquid into the micro-channels. A single-phase numerical scheme that utilizes the k–e turbulent model and a method for determining the extent of the lami...

We demonstrate a fabrication procedure for the direct integration of micro-ball lenses on planar integrated optical channel waveguide chips with the aim to reduce the divergence of light that arises from the waveguide in both horizontal and vertical directions. Fabrication of the lenses is based on photoresist reflow which is a procedure that allows for the use of photolithography for careful a...

Hydrodynamics plays a major role in transport of heat and mass transfer microchannels. This includes flow patterns regimes which the micro-channels are operated. The have impact properties. Another important aspect is pressure drop micro-channels. In present review, experimental Computational Fluid Dynamics (CFD) studies covering all above aspects been covered. effect geometrical parameters lik...

We have used the TOPAS simulation framework to model direct conversion of 511 keV gamma rays electrons in a micro-channel plate (MCP) constructed from thin laminae heavy-metal-loaded dielectric such as lead-glass, patterned with micro-channels (LMCP). The serve converter ray primary electron within depth channel-forming surface that penetrates channel (‘surface conversion’). channels are coated...

mechanism of oceanic control of climate. They constitute a repository for heat, fresh water and gases such as carbon dioxide, all of which are exchanged at the ocean–atmosphere interface.On the largest scale, the water masses spread and fill the ocean basins. These huge bodies of water are also the engines of large-scale ocean circulation, one that is primarily driven by so-called North Atlanti...
