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.
A greenhouse gas (GHG) is any gas in the atmosphere that absorbs and emits radiation in the thermal infrared range. These are the fundamental cause of the greenhouse effect, which results in increased temperatures on Earth. The greenhouse effect occurs as the gases reach Earthâs surface. As the short wave energy heats the surface, some of the longer wave energy radiates back into the atmosphere and back into space. Greenhouse gases absorb some of the energy and trap it in the lower atmosphere.
