Fuel cells are being considered increasingly as a viable alternative energy source for automobiles because of their clean and efficient power generation. Numerous technological concepts have been developed and compared in terms of safety, robust operation, fuel economy, and vehicle performance. However, several issues still exist and must be addressed to improve the viability of this emerging t...

electromagnetic radiation emitted by cell-phones is a new health hazard, especially when they are used inside closed metal bodies such as cars, elevators etc. the modern wireless devices like bluetooth further enhance the effect of this radiation. the present studies were taken to get quantitative information about the actual power density levels to which a human brain is exposed inside a vehic...

Nanocomposites containing poly(methyl methacrylate) (PMMA) and surface functionalized Multi-Walled Carbon Nanotubes (MWNTs) were synthesized. The dispersion of MWNTs in PMMA was characterized using Transmission Electron Microscopy (TEM).The synthesized nanocomposites were successfully foamed using a simple method based on the in-situ generation of supercritical carbon dioxide (CO2</sub...

Tuning recombinant protein expression is an approach which can be successfully employed for increasing the yield of recombinant protein production in high cell density cultures. On the other hand, most of the previous results reported the optimization induction conditions during batch and continuous culture of recombinant E. coli, and consequently fed-batch culture have received less attention....

Background: &nbsp;Cell viability is an important factor in radiation therapy and thus is a method to quantify the effect of the therapy. Materials and Methods: The viability of human hepatoma (HepG2) cells exposed to radiation was evaluated by both the MTT and Trypan blue assays. The cells were seeded on 96 well-plates at a density of 1 x 104 cells/well, incubated overnight, and irradiated with...
