hot spots are among the most serious operational issues in furnaces as they may result in the destruction of tubes. hence, it is essential to locate such hot spots precisely on the tube surfaces inside the industrial furnaces in order to secure a safe design and operation. in the current study, we have extended the model proposed by talmor in order to precisely locate the combustion hot spots o...

one of temperature estates is hot day occurrence. in order to recognize the mechanism of this estate, surveying its spatial behavior is crucially important. in current paper it has been attempted to recognized widespread hot days and their spatial distribution by using statistical methods. accordingly maximum temperature database of iran during 1962-2008 has been used. the analyses result has i...

Evolutionary analysis of microbes at the community level represents a new research avenue linking ecological patterns to evolutionary processes, but remains insufficiently studied. Here we report a relative evolutionary rates (rERs) analysis of microbial communities from six diverse natural environments based on 40 metagenomic samples. We show that the rERs of microbial communities are mainly s...

This topic introduces the concept of Hot Swapping DC power buses and why hotswapping has become a mainstream requirement, particularly in the telecommunications industry. Several methods of implementing hot swap will be provided along with the pros and cons of each method. Finally, a hot swap design utilizing a Hot Swap Power Manager will be presented for a typical -48V telecom

Vickers Hot Springs is located near the rural Southern California town of Ojai, and local residents have long enjoyed soaking in the sulfuric pools. But as knowledge of the springs spread, the area saw increases in fights, traffic, burglaries, and drug use. In response, two residents purchased the land and committed to restore the property while allowing limited public access, subsequently gene...
