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.
1 Water vapor is the most abundant greenhouse gas. 2  Most scientists believe that water vapor produced directly by human activity contributes very little to the amount of water vapor in the atmosphere. 3  Therefore, the U.S. Energy Information Administration (EIA) does not estimate emissions of water vapor.here are other greenhouse gases that are not counted in United States or international greenhouse gas inventories: 1  Water vapor is the most abundant greenhouse gas. 2  Ozone is technically a greenhouse gas because it has an effect on global temperature.
