An airlock, air-lock or air lock, often abbreviated to just lock, is a compartment with doors which can be sealed against pressure which permits the passage of people and objects between environments of differing pressure or atmospheric composition while minimizing the change of pressure in the adjoining spaces and mixing of environments. The lock consists of a relatively small chamber with two airtight doors in series which do not open simultaneously.
The Queen's Medical Centre is a teaching hospital situated in Nottingham, England. Until February 2012, when it was surpassed by the Royal London Hospital, it was the largest hospital in the United Kingdom. It is managed by Nottingham University Hospitals NHS Trust.
A diving bell is a rigid chamber used to transport divers from the surface to depth and back in open water, usually for the purpose of performing underwater work. The most common types are the open-bottomed wet bell and the closed bell, which can maintain an internal pressure greater than the external ambient. Diving bells are usually suspended by a cable, and lifted and lowered by a winch from a surface support platform. Unlike a submersible, the diving bell is not designed to move under the control of its occupants, nor to operate independently of its launch and recovery system.
A bunk bed is a type of bed in which one bed frame is stacked on top of another, allowing two or more beds to occupy the floor space usually required by just one. They are commonly seen on ships, in the military, and in hostels, dormitories, summer camps, children’s bedrooms, and prisons.
A bed is an item of furniture that is used as a place to sleep, rest, and relax.
An emergency exit in a structure is a special exit for emergencies such as a fire: the combined use of regular and special exits allows for faster evacuation, while it also provides an alternative if the route to the regular exit is blocked.
An infant bed is a small bed especially for infants and very young children. Infant beds are a historically recent development intended to contain a child capable of standing. The cage-like design of infant beds restricts the child to the bed. Between one and two years of age, children are able to climb out and are moved to a toddler bed to prevent an injurious fall while escaping the bed.
A diving chamber is a vessel for human occupation, which may have an entrance that can be sealed to hold an internal pressure significantly higher than ambient pressure, a pressurised gas system to control the internal pressure, and a supply of breathing gas for the occupants.
A wheelchair-accessible van is a vehicle that has been modified by increasing the interior size of the vehicle and equipping it with a means of wheelchair entry, such as a wheelchair ramp or powered lift.
Lautering is the beer brewing process that separates the mash into clear liquid wort and residual grain. Lautering usually consists of three steps: mashout, recirculation, and sparging.
Eimsbüttel is one of the seven boroughs (Bezirke) of Hamburg, Germany. In 2020 the population was 269,118.
In manufacturing, the simulated moving bed (SMB) process is a highly engineered process for implementing chromatographic separation. It is used to separate one chemical compound or one class of chemical compounds from one or more other chemical compounds to provide significant quantities of the purified or enriched material at a lower cost than could be obtained using simple (batch) chromatography. It cannot provide any separation or purification that cannot be done by a simple column purification. The process is rather complicated. The single advantage which it brings to a chromatographic purification is that it allows the production of large quantities of highly purified material at a dramatically reduced cost. The cost reductions come about as a result of: the use of a smaller amount of chromatographic separation media stationary phase, a continuous and high rate of production, and decreased solvent and energy requirements. This improved economic performance is brought about by a valve-and-column arrangement that is used to lengthen the stationary phase indefinitely and allow very high solute loadings to the process.
Consent searches are searches made by police officers in the United States based on the voluntary consent of the individual whose person or property is being searched. The simplest and most common type of warrantless searches in the United States are searches based upon consent. No warrant, probable cause or reasonable suspicion is required to perform a search if a person, or someone else with the proper authority, consents to a search.
Road signs in Norway are regulated by the Norwegian Public Roads Administration, Statens vegvesen.
In scuba diving, the rule of thirds is a rule of thumb used by divers to plan dives so they have enough breathing gas remaining in their diving cylinder at the end of the dive to be able to complete the dive safely. This rule generally only applies to diving in overhead environments, such as caves and wrecks, where a direct ascent to the surface is impossible and the divers must return the way they came.
A toddler bed is a small bed designed for toddlers. A child grows capable of escaping an infant bed around one and a half or two years of age, at which they are often transitioned to a toddler bed. They become too large for a toddler bed between the ages of five and seven years, and will then transition to an ordinary bed.
A flatbed truck is a type of truck which can be either articulated or rigid. As the name suggests, its bodywork is just an entirely flat, level 'bed' with no sides or roof. This allows for quick and easy loading of goods, and consequently they are used to transport heavy loads that are not delicate or vulnerable to rain, and also for abnormal loads that require more space than is available on a closed body.
The Bluffton University bus crash was an automobile crash that occurred during the early morning hours of March 2, 2007, on Interstate 75 in Atlanta, Georgia. A chartered motorcoach was carrying 33 members of the Bluffton University baseball team from Bluffton, Ohio, on their way to play Eastern Mennonite University during spring break in Sarasota, Florida. The group planned to travel without an overnight stop on the approximately 900-mile, 18-hour trip. The trip went without incident from Bluffton south to a motel in Adairsville, Georgia, at which time a relief driver began operating the bus for the second half of the trip.
Arizona v. Johnson, 555 U.S. 323 (2009), is a United States Supreme Court case in which the Court held, by unanimous decision, that police may conduct a pat down search of a passenger in an automobile that has been lawfully stopped for a minor traffic violation, provided the police reasonably suspect the passenger is armed and dangerous.
A hospital bed or hospital cot is a bed specially designed for hospitalized patients or others in need of some form of health care. These beds have special features both for the comfort and well-being of the patient and for the convenience of health care workers. Common features include adjustable height for the entire bed, the head, and the feet, adjustable side rails, and electronic buttons to operate both the bed and other nearby electronic devices.
