Abstract-Since highways are widely used modes, it is necessary that it should be maintained properly. Subgrade being the support for the whole pavement, it needs the utmost care in its construction. Many suggestions have been put forward by various scientists to improve the subgrade. The usually adopted methods are stabilization methods. This paper deals with the improvement of properties of ka...

We consider an information-theoretic model studying the conditions when a separation between the dynamics of a ’proto-cell’ and its proto-symbolic representation becomes beneficial in terms of preserving the proto-cell’s information in a noisy environment. In particular, we are interested in understanding the behaviour at the “error threshold” level which, in our case, turns out to be a whole “...

Now a days, In most of the thermal power plant, where low-pressure steam is being exhausted to the atmosphere as a waste steam. This waste heat could be use to operate many small preheating or cooling equipments or small scale plants. There are many refrigeration systems present for refrigeration and air condition purpose. Such as air refrigeration, vapour compression, vapour absorption etc. In...

BACKGROUND Environmental and health-related effects of solid waste material are considered worldwide problems. The aim of this study was to assess the volume and impact of Arab scientific output published in journals indexed in the Science Citation Index (SCI) on solid waste. METHODS We included all the documents within the SCI whose topic was solid waste from all previous years up to 31 Dece...

F or years, the Halliburton Company followed local standards in its management of Brazil's state-owned oil company in Catu. This meant discharging stormwater runoff and wastewater effluents directly into the Catu River, untreated. Then, in 1994, the Dallas, Texas-based energy and engineering company initiated new company-wide environmental standards. In Catu, that meant an effort to reduce the ...
