Received Sep 12, 2016 Revised Oct 20, 2016 Accepted Nov 6, 2016 In India Electrical Energy is generated mainly Coal based Thermal Power stations and hydro Electric Power Stations. The main aim of power generating company is to provide good quality and reliable p ower to consumers at minimum cost. The problem of Combined Economic and Emission Dispatch deals with the minimization of both fuel cos...

One important aspect of supply chain management is the maintenance of an efficient and costeffective system for the distribution of goods or products to retailing outlets. Nowadays, it is almost inevitable that an efficient distribution network can only be achieved with the support of computer based optimization software. We show in this paper how an evolutionary algorithm (EA) can play an effe...

BACKGROUND Fuel filling stations workers and automobile workshops mechanics are consistently exposed to gasoline hydrocarbons during their occupation, this may cause DNA damage. Objective of this study was to evaluate the level of DNA damage in subjects occupationally exposed to these hydrocarbons. METHODS Comet assay was performed on blood lymphocytes of exposed subjects to assess the probab...

An important barrier towards the introduction of fuel cell vehicles (FCVs) running on hydrogen is the lack of widespread refueling infrastructure. The niche of buses for public transport, taxis and deliverers with a local application area might not be large enough to generate the reductions of FCV costs that are necessary for a general technology switch. Thus, fuel availability at trunk roads p...

Historically, gasoline and diesel fuels have been used for transportation, but the possible decline of oil supplies in the future is forcing nations to consider alternative fuels. Most technically and economically feasible alternative fuels have a lower energy density than gasoline, which results in a shorter range for these vehicles. This necessitates a greater need for convenient access to re...

Bike Sharing System (BSS) is a green mode of transportation that is employed extensively for short distance travels in major cities of the world. Unfortunately, the users behaviour driven by their personal needs can often result in empty or full base stations, thereby resulting in loss of customer demand. To counter this loss in customer demand, BSS operators typically utilize a fleet of carrie...

In December 2000, the ship 'Coral Bulker' ran aground at the entrance of the port of Viana do Castelo (North-west coast of Portugal). A large amount of fuel oil was spilled and part of it reached the shore. To evaluate the spatial and temporal impact of this oil spill, a field study, and several laboratory toxicity tests were performed using Mytilus galloprovincialis as biological indicator of ...

The current transportation sector in the United States is heavily relied on private automobile, consuming a large amount of fuel energy and producing a large quantity of greenhouse gases. Shared mobility, such as ridesharing and bikesharing, could potentially improve urban sustainability by decreasing the total vehicle-miles, saving fuel energy and reducing greenhouse gases. This research proje...

The distribution of aliphatic and aromatic hydrocarbons was determined in surface sediments collected at 36 stations along the Galicia continental shelf (NW Spain), following the Prestige oil spill. Sampling was performed in December 2002, just after the accident, and in February and September 2003. Concentrations of PAHs (summation operator 13 parent components) were in the range of 0.9-422 mi...
