The use of non-renewable energy systems for agriculture in remote areas has brought up lots of disadvantages to the environment as well as the public.In order to encounter this problem a stirling engine system,which utilizes the solar energy as its resources and releases no exhaust to the environment is proposed throughout the present book.The hybrid renewable energy systems are becoming popular as stand -alone power syst- ems for providing electricity in remote areas due to advances in renewable energy technologies and subsequent rise in prices of petroleum prod- ucts. A hybrid energy system,usually consists of two or more renewable energy sources used together to provide increased efficiency. In this concern, renewable energy system such as solar and wind can be used successfully in rural locations where grid connection is not possible. Since hybrid systems include both solar & wind, they allow the power user to benefit from the advantage of both forms of energy. Obviously, solar panels don't provide power during the night,but that's when the wind usually picks up and conversely,on the longest, hottest days of days of summer,the wind often doesnt blow, but sun is at its weakest.

Petroleum Products Altered Cardiovascular Funct...

Major problem facing dwellers in Niger Delta environment of Nigeria is related to pollution by petroleum products. This pollution often results to diffused chronic exposure to massive acute exposure as occurs in blow outs and vandalism. These concentrations may lead to physiological stress and dysfunction. This study investigated the effects of petroleum products(diesel, kerosene and petrol) and their water soluble fractions(WSF) on cardiovascular function, packed cell volume and plasma lipid profile in experimental rats(Rattus norvegicus).The petroleum products and their WSF were administered into rats for three weeks. They were anaesthetized with a mixture of urethane and alpha chloralose in 0.9 saline. the rats were cannulated using a polythene catheter filed with solution of heparin. The femoral artery was cannulated for recording of the arterial blood pressure and heart rate. Blood samples were collected for plasma lipids assay while internal organs were harvested and weighed. The control rats received water only. The study revealed that petroleum fractions and their WSF altered cardiovascular function and plasma lipids profile, while fall in PCV was not significant.

Industrial Diffusion Burners

Study the development of diffusion flame forms a special importance in applications and design of industrial burners. Review of previous researches exhibit the need to expand the study of diffusion flame stability and the effect of geometric shapes for the bluff-bodies. Properties of diffusion flame stability were measured: (blow-off flame, critical flame height Hc, height blow-off flame Hlift). The results were represented by charts that take into account the possibility of proper selection of bluff-body and diffusion burner in industrial applications. In this book, it was possible to limit the emission of pollutants of the combustion products for diffusion flame under high stability conditions by activating the good mixing of fuel liquefied petroleum gas (LPG) and air in the primary Diffusion flame, and increase recirculation air flow by Chang the geometrical shape of bluff-body.

Oil Pollution and Marine Ecology
168,00 CHF *
ggf. zzgl. Versand

During the dozen years in which I have been actively interested in oil pollution, not only has the quantity of petroleum products con sumed in industrially developed nations (and thus the volume of crude oil shipped to them) greatly increased; disastrous accidents, particularly the wreck of Torrey Canyon in the approaches to the English Channel and the blow-out of Well A-21 off Santa Barbara, California, have made the public in general aware for the first time of the implications of their growing appetite for oil and the goods made from it. Concern over the pollution of coastal waters and sea-shores has been expressed ever si nce the 1920s by a small but active band of ornithologists, wildfowlers and seaside hotel-keepers but, even now, the international legislation which their efforts initiated adequately regulates only a fraction of the world's tanker traffic. In Britain, Torrey Canyon sparked off an interest in oil pollution and, by extension, other environmental troubles which had previously been aired only rarely in the mass communications media. Biologists and workers in various technologies were stimulated to carry out a wide variety of investigations both in the field and the laboratory, while even the most laggard member of the oil industry must now feel bound to give some thought to the effect of spills and discharges on human amenity or the natural environment.

The Prototype
34,90 CHF *
ggf. zzgl. Versand

An ancient American Indian chief proclaimed that the God of this world would 'curse your riches that they will become slippery to you that you cannot hold onto them.' It's an odd, yet descriptive choice of words. When you consider every part of our worldwide economy is based on petroleum and derivatives, then the word 'slippery' becomes appropriate. When a car runs out of oil, the motor seizes and disgorges its internal parts through a gaping hole in the side of the motor. Without oil (or the need for it,) our world is no longer functional. 1993 introduced an incredible invention that was a perpetual motion machine. Whether it worked or not was never publicly proven. 'The Prototype' is a discussion of how such a thing would be viewed by the 'powers that be.' Dismal as it seems, the world isn't ready to receive such an abrupt change in direction. Every institution would blow apart at the seams. Oppression, even genocide are inevitable results of greed. There are those who would rise above the devastation, but others who would promote it.fromhose soul purpose is to exert influence and force upon others to achieve their goals. in mankind is that aThere 'The Prototype' follows the lives of three individuals who attempt to free the world of its dependence on petroleum. It takes unique talents to accomplish such a thing. Keith De Code, called Dakota by friends, is a hero waiting to happen. He sits at the bottom of his pit of despair. When a poker buddy slips him information just before dying, Dakota pieces everything together and steps up to the plate. What lies before him is better not known. He should certainly cower from the ensuing cataclysm. Dakota faces the consequent catastrophe, but is he good enough to overcome powerful nations and organizations with decades of corruption? Does one man have the power to overcome a world of evil? .
