The turbine units are at the forefront of equipment in process pumping crude oil and exporting it to ports, where there many types turbines used different sites Iraqi stations whether or electrical power production stations. One most important is gas turbine, which frequently depots. remarkable depots Iraq Zubair-1 / Basra that exports around 850,000 barrels per day (B/D). Therefore, should con...

BACKGROUND Diesel exhaust exposure may cause acute irritant-induced asthma and potentiate allergen-induced asthma. There are no previous reports of occupational asthma due to diesel exhaust. AIMS To describe occupational asthma with latency in workers exposed to diesel exhaust in bus garages. METHODS The Shield database of occupational asthma notifications in the West Midlands, UK, was sear...

Traffic-related sources have been recognized as a significant contributor of particulate matter particularly within major cities. Exhaust and non-exhaust traffic-related sources are estimated to contribute almost equally to traffic-related PM10 emissions. Non-exhaust particles can be generated either from non-exhaust sources such as brake, tyre, clutch and road surface wear or already exist in ...

Motor vehicles are major sources of gas-phase organic carbon, which includes volatile organic compounds (VOCs) and other compounds with lower vapor pressures. These emissions react in the atmosphere, leading to the formation of ozone and secondary organic aerosol (SOA). With more chemical detail than previous studies, we report emission factors for over 230 compounds from gasoline and diesel ve...

While EER (Exhaust Energy Recovery) has been widely pursued for improving the total efficiency and reducing CO2 emissions of internal combustion engines, the maximum regenerated power from the exhaust energy has been proposed and calculated in terms of endoreversible cycle. In this paper, based on the experimental data of an EER system installed on a light duty gasoline engine, the exhaust ener...

Application of Compressed Natural Gas (CNG) in diesel engines has always been important, especially in the field of automotive engineering. This is due to easy accessibility, better mixing quality and good combustion characteristics of the CNG fuel. In this study the application of CNG fuel along with diesel oil in a heavy duty direct-injection automotive diesel engine is experimentally investi...

BACKGROUND Particulate pollution is associated with the occurrence of asthma and allergy. The model pollutant, diesel exhaust particles, can participate with allergens in starting and exacerbating allergic airway diseases in part by production of reactive oxygen species. Glutathione-S-transferases (GSTs) can metabolise reactive oxygen species and detoxify xenobiotics present in diesel exhaust p...
