Endovascular aneurysm repair (EVAR) is a type of minimally-invasive endovascular surgery used to treat pathology of the aorta, most commonly an abdominal aortic aneurysm (AAA). When used to treat thoracic aortic disease, the procedure is then specifically termed TEVAR for "thoracic endovascular aortic/aneurysm repair."
An onboard refueling vapor recovery system (ORVR) is a vehicle fuel vapor emission control system that captures volatile organic compounds (VOC, potentially harmful vapors) during refueling. [1][page needed] There are two types of vehicle fuel vapor emission control systems: the ORVR, and the Stage II vapor recovery system. [2]
Crankcase ventilation system. A crankcase ventilation system (CVS) removes unwanted gases from the crankcase of an internal combustion engine. The system usually consists of a tube, a one-way valve and a vacuum source (such as the inlet manifold). The unwanted gases, called "blow-by", are gases from the combustion chamber which have leaked past ...
Porous pottery and coarse cloth maximize the area for evaporation. An evaporative cooler (also known as evaporative air conditioner, swamp cooler, swamp box, desert cooler and wet air cooler) is a device that cools air through the evaporation of water. Evaporative cooling differs from other air conditioning systems, which use vapor-compression ...
This was the first mass market system with controls on the dash and an electric clutch. [14] This system was also compact and serviceable with all of its components installed under the hood or in the cowl area. [15] Combining heating, cooling, and ventilating, the new air conditioning system for the Nash cars was called the "All-Weather Eye". [16]
In woodwind instrument repair, a smoke test involved plugging one end of an instrument and blowing tobacco smoke from the tester's mouth into the other to test for leaks. Escaping smoke revealed improperly seated pads and faulty joints (i.e. leaks). After this test the instrument was cleaned to remove nicotine and other deposits left by the ...
The most common leak detection method for pipeline operators is called the Supervisory Control And Data Acquisition (SCADA) system. This system uses a series of sensors to track data such as pressure, flow rates, temperature, and whether valves are open or closed.
Fugitive emissions are leaks and other irregular releases of gases or vapors from a pressurized containment – such as appliances, storage tanks, pipelines, wells, or other pieces of equipment – mostly from industrial activities. In addition to the economic cost of lost commodities, fugitive emissions contribute to local air pollution and ...
