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.
Figure 3 shows the EU-28 greenhouse gas emissions broken down by main source sectors. 'Fuel combustion and fugitive emissions from fuels (without transport)' is responsible for 55 % of EU-28 greenhouse gas emissions in 2015. In 1990 this source sector was even more dominant. Fuel combustion for transport (including international aviation) is the second most important source sector with 23 % in 2015; it has increased its contribution significantly since 1990. Greenhouse gas emissions from agriculture contribute with 10 % to EU-28 total greenhouse gas emissions.
