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 takes in (absorbs) and gives off (emits) radiation in the heat (infrared) wavelength range. Greenhouse gases cause the greenhouse effect, which results in increased temperatures on Earth.ut greenhouse gases in the atmosphere absorb some of the infrared radiation energy and âtrapâ it in the lower atmosphere. Less heat radiates into space, and the Earth is warmer. Many greenhouse gases occur naturally. Carbon dioxide, methane, water vapor, and nitrous oxide are naturally present in Earthâs atmosphere.
