any change in the refractive index of a laser active medium can lead to serious degradation of beam quality, laser beam modes, laser performance and variation in the intensity distribution. alteration in the refractive index of laser active medium is especially notable in high power lasers. it is clear that in the laser beam production, the pumping agent induces a great amount of heat which...
Date: August 25 Place: Room 5234 (oral), Room 6302 (poster) Organizers: Anand Bahadur Singh & Jae-Won Oh Contact email address: [email protected] Purpose: It is now well established that green house gases such as CO2, ozone and also global temperature is increasing all over the world. Records from long term data on pollen monitoring from several countries particularly Europe and USA reveal t...
For a few decades has proposed sustainable developing in different sciences and professions including architecture and urbanization and its origins is in environmental crises and also excessive use of fossilized energies in the world. problems such as global warming, increasingly developing of green house gases in atmosphere that its origin is in global warming , air and soil pollution, an...
Global Warming is the greatest challenge that the world is facing today. It is very important to take preventive measures before this problem poses a serious threat to the mankind. Power Plants play a major role in green house gas emissions. Nearly 21.3% of green house gases are emitted by these power plants alone. In this paper we try to propose a computational approach to reduce these carbon ...

126 abstract: in this research we studied the effects of cyclic hydration and dehydration of cysts of artemia urmiana and artemia parthenogenetica on the hatching percentage, survival and growth. the experiment was carried out in 3 treatments (1-3 hydration/dehydration cycles) with 3 replicates for each treatment. later effects of cold preservation at -20°c during three time periods were ...
The evolution of Diesel engines in the last decades has been driven by the stringent pollution legislation and increasing environmental concern. In this context the Diesel engine appears like a very good candidate due to its naturally high efficiency. However, in order to further reduce engine out pollutant and green house gases to the required limits, a detailed study of the fuel-air mixing an...
