The typical patient on whom a surgeon would be tempted to perform a laparoscopy-assisted vaginal hysterectomy would be one with myomata uteri, a history of pelvic inflammatory disease, a history of previous pelvic surgeries such as cesarean section, or significant endometriosis with adhesions to bowel.
Diesel fuel is a mixture of hydrocarbons whichâduring an ideal combustion processâwould produce only carbon dioxide (CO 2) and water vapor (H 2 O). Indeed, diesel exhaust gases are primarily composed of CO 2, H 2 O and the unused portion of engine charge air.ince the adoption of first emission standards, emissions of pollutants from diesel engines have been reduced by as much as two orders of magnitude. More recent emission regulations also introduce emission limits on CO 2 and other greenhouse gases.
Combustion is a type of chemical reaction that usually involves oxygen. For combustion to occur, oxygen combines with another compound to form water and carbon dioxide. Combustion usually results in the production of light and heat in the form of a flame. There are two types of combustion: incomplete and complete combustion. Incomplete combustion is the type of combustion in which there is not enough oxygen or a high enough temperature for the carbon to turn into carbon dioxide.
