In December 1968, during its annual meeting, the American Association for the Advancement of Science convened a symposium on the Global Effects of Environmental Pollution. In the words of the organizer of this symposium, Mr. S. Fred Singer, the purposes "were to discuss the worldwide effects which may arise from local pollution and to try to uncover, if possible, hitherto unsuspected effects wh...

Byproducts generated from food industries, such as olive oil mills, have been studied to decrease harmful pollution and their environmental consequences. In this work, a new thermal pretreatment and saprobic fungal incubation to detoxify alperujo (two-phase olive mill waste) have been evaluated in view of its use as fertilizer in agriculture. The sequential use of both methods simplifies the th...

Objective of the power systems firm is to achieve the maximum profit and customer goodwill by providing reliable and quality power supply. This power system operation problem is solved by Optimal Power Flow (OPF). It gives requirement of operating states which satisfy the objective of the firm. Thermal power plants are the main source of power generation. Fuel cost of these power plants has to ...

Persistent thermohaline pollution at a site along the northern coast of Israel, due to power and desalination plants, is used as a natural laboratory to evaluate the effects of rising temperature and salinity levels on benthic foraminifera living in shallow hard-bottom habitats. Biomonitoring of the disturbed area and a control station shows that elevated temperature is a more significant stres...

In the present paper, a complete literatures review of thermal barrier coating applications in diesel engines is performed to select a proper type and to find coating effects. The coating system has effects on the fuel consumption, the power and the combustion efficiency, pollution contents and the fatigue lifetime of engine components. Usually there are several beneficial influences by appl...

Wastewaters from power plants is a major concern for environmental protection. After the water used in thermal plant, heated effluent again discharged same body where it taken. This not only disturbs aquatic life but also affects balance of ecosystem. paper presents background pollution, modelling approach and analysis methods prediction pollution. A two-dimensional model Sava River discussed. ...
