Recently, a lot of energy efficient techniques have been developed to reduce the usage of the carbon intensive energy (brown energy) of databases. There is a new opportunity to reduce the brown energy usage: renewable energy (green energy) has been used to at least partially power computer systems. The key challenge of exploiting green energy sources is that they are variable and intermittent. ...

Global warming has today turned to one of the most important environmental issues due tooveruse of fossil fuels, and it needs serious attention. Since the mid-1970s, an urgent needwas therefore felt around the world to reduce the use of energy for heating and cooling inbuildings. Using green covers, especially green facades, in appropriate environmentalconditions can be regarded as a method to ...

Sustainable building practices can considerably reduce building’s environmental impact in energy consumption. Covering a building envelope with green vegetation, such as green roof and green wall, is considered a sustainable construction practice, as green vegetation has a positive performance in energy savings. It reduces heat flux and solar reflectivity, generates evaporative cooling, increas...

BACKGROUND & AIMS Bioactive ingredients have been shown to reduce appetite and energy intake. The magnitude of these effects might depend on energy balance why it was investigated how capsaicin, green tea, CH-19 sweet pepper as well as green tea and capsaicin affect appetite and energy intake during respectively negative and positive energy balance. METHODS 27 subjects were randomized to thre...

conclusions the present research demonstrated that the ultrasonic (us) process can be utilized as an effective and simple method for treatment of mg dye in an aqueous solution. moreover, the eeo is directly proportional to the mg concentration and power density and inversely proportional to temperature and mechanical agitation, which can be predicted by the obtained empirical kinetics model. co...

Increasing energy efficiency and reducing the use of hazardous materials are the main goals of Green computing. Energy efficiency has become an important issue in today’s global IT scenario. From embedded systems to large scale systems, all sectors of IT are facing this challenge. The various facts and challenges faced in the Green IT environment are discussed in this paper. This paper also foc...
