introduction : heat shock proteins (hsps) are molecular chaperones involved in protein folding, stability and turnover, and due to their role in cancer progression, the effect of low power laser irradiation (lpli) on the expression of hsp70 and hsp90 in jurkat e6.1 t-lymphocyte leukemia (jelt) cell line was investigated in vitro. methods : jetl cells were irradiated with lpli at 635nm and 780m ...
the ever increasing rate of power consumption has led to an increase in public exposure to extremely low frequency magnetic fields (elf-mfs) and brought severe concerns about their health effects. considering previous studies and the facts about potential health effects of these fields, the present study aimed to evaluate the elf-mf flux densities from power distribution lines near hospitals in...
in this study an ultra-broad band, low-power, and high-gain cmos distributed amplifier (cmos-da) utilizing a new gain-cell based on the inductively peaking cascaded structure is presented. it is created bycascading of inductively coupled common-source (cs) stage and regulated cascode configuration (rgc).the proposed three-stage da is simulated in 0.13 μm cmos process. it achieves flat and high ...
A sensor network consists of many low-cost, low-power, and multifunctional sensor nodes. One of the most important issues in sensor networks is to increase network lifetime, and there have been researches on the problem. In this paper, we propose a routing mechanism to prolong network lifetime, in which each node adjusts its transmission power to send data to its neighbors. We model the energy ...
