BOD test bottles at the laboratory of a wastewater treatment plant. Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time period.
The Sarco pod (also known as Pegasos, and sometimes referred to as a "suicide pod" [1]) is a euthanasia device or machine consisting of a 3D-printed detachable capsule mounted on a stand that contains a canister of liquid nitrogen to die by suicide through inert gas asphyxiation. "Sarco" is short for "sarcophagus".
BOD Bottle BOD test bottles at the laboratory of a wastewater treatment plant. BOD Bottle or an incubation bottle is a main apparatus used for the Biological Oxygen Demand (BOD) test. During the five-day BOD or BOD5 test process, the BOD bottle is used for incubating diluted samples under the 20 °C or 68 °F of temperature.
A body broker (also non-transplant tissue banks) is a firm or an individual that buys and sells cadavers or human body parts. Whereas the market for organ transplantation is heavily regulated in the United States, the use of cadaver parts for research, training, and other uses is not.
The General Dynamics F-111 Aardvark used cabin ejection, where both side-by-side seats were in a single 3000 lb (1360 kg) capsule. [2] Three of the four Rockwell B-1A prototypes also used cabin ejection. They had a single capsule "roughly the size of a mini-van" [3] for all four crew members.
Oxygen converter being charged at ThyssenKrupp steel mill in Duisburg (Germany). Basic oxygen steelmaking (BOS, BOP, BOF, or OSM), also known as Linz-Donawitz steelmaking or the oxygen converter process, [1] is a method of primary steelmaking in which carbon-rich molten pig iron is made into steel.
An escape pod, escape capsule, life capsule, or lifepod is a capsule or craft, usually only big enough for one person, used to escape from a vessel in an emergency. An escape ship is a larger, more complete craft also used for the same purpose. Escape pods are ubiquitous in science fiction but are only used in a few real vehicles.
A pod developed for both fixed-wing aircraft and helicopters, fitted with a single M3.50 caliber machine gun. [3] The pod carried 750 rounds of ammunition and provided a pneumatic charging system for the weapon. [5] This system was used on the JOV-1A and UH-1 series of helicopters. [6] [7]
