The clove hitch is a type of knot. Along with the bowline and the sheet bend, it is often considered one of the most important knots. A clove hitch is two successive half-hitches around an object. It is most effectively used as a crossing knot. It can be used as a binding knot, but is not particularly secure in that role. A clove hitch made around the rope's own standing part is known as either two half-hitches or buntline hitch, depending on whether the turns of the clove hitch progress away from or towards the hitched object.
Although the name clove hitch is given by Falconer in his Dictionary of 1769, the knot is much older, having been tied in ratlines at least as early as the first quarter of the sixteenth century. This is shown in early sculpture and paintings. A round turn is taken with the ratline and then a hitch is added below. The forward end is always the first to be made fast.
The difference between two half hitches and the clove hitch is that the former, after a single turn around a spar, is made fast around its own standing part, while the latter is tied directly around the spar.
A dead man's switch is a switch that is designed to be activated or deactivated if the human operator becomes incapacitated, such as through death, loss of consciousness, or being bodily removed from control. Originally applied to switches on a vehicle or machine, it has since come to be used to describe other intangible uses, as in computer software.
A power cord, line cord, or mains cable is an electrical cable that temporarily connects an appliance to the mains electricity supply via a wall socket or extension cord. The terms are generally used for cables using a power plug to connect to a single-phase alternating current power source at the local line voltage. The terms power cable, mains lead, flex or kettle lead are also used. A lamp cord is a light-weight, ungrounded, single-insulated two-wire cord used for small loads such as a table or floor lamp.
A squat toilet is a toilet used by squatting, rather than sitting. This means that the defecation posture used is to place one foot on each side of the toilet drain or hole and to squat over it. There are several types of squat toilets, but they all consist essentially of a toilet pan or bowl at floor level. Such a toilet pan is also called a "squatting pan". A squat toilet may use a water seal and therefore be a flush toilet, or it can be without a water seal and therefore be a dry toilet. The term "squat" refers only to the expected defecation posture and not any other aspects of toilet technology, such as whether it is water flushed or not. Squat toilets are used all over the world, but are particularly common in some Asian and African nations, as well as in some Muslim countries. In many of those countries, anal cleansing with water is also the cultural norm and easier to perform than with toilets used in a sitting position. They are also occasionally found in some European and South American countries. Squat toilets are regarded as traditional by many, and are being phased out in favour of sitting toilets or even high-tech sitting toilets.
On trains, the expression emergency brake has several meanings:
An assisted living residence or assisted living facility (ALF) is a housing facility for people with disabilities or for adults who cannot or who choose not to live independently. The term is popular in the United States, but the setting is similar to a retirement home, in the sense that facilities provide a group living environment and typically cater to an older adult population. There is also Caribbean assisted living, which offers a similar service in a resort-like environment.
A public toilet, restroom, public bathroom or washroom is a room or small building with toilets and sinks for use by the general public. The facilities are available to customers, travelers, employees of a business, school pupils and prisoners and are commonly separated into male and female toilets, although some are unisex, especially for small or single-occupancy public toilets.
A Prusik is a friction hitch or knot used to attach a loop of cord around a rope, applied in climbing, canyoneering, mountaineering, caving, rope rescue, ziplining, and by arborists. The term Prusik is a name for both the loops of cord used to tie the hitch and the hitch itself, and the verb is "to prusik". More casually, the term is used for any friction hitch or device that can grab a rope. Due to the pronunciation, the word is often misspelled Prussik, Prussick, or Prussic.
A nuchal cord is when the umbilical cord becomes wrapped around the fetus's neck. Symptoms present in the baby shortly after birth from a prior nuchal cord may include duskiness of face, facial petechia, and bleeding in the whites of the eye. Complications can include meconium, respiratory distress, anemia, and stillbirth. Multiple wraps are associated with greater risk.
Accessible toilets are toilets that have been specially designed to better accommodate people with physical disabilities. Persons with reduced mobility find them useful, as do those with weak legs, as a higher toilet bowl makes it easier for them to stand up. Additional measures that can be taken to add accessibility to a toilet include providing more space, adding grab bars to ease transfer to and from the toilet seat, and providing extra room for a caregiver if necessary. Some countries have requirements concerning the accessibility of public toilets. Toilets in private homes can be modified (retrofitted) to increase accessibility.
An aircraft lavatory or plane toilet is a small room on an aircraft with a toilet and sink. They are commonplace on passenger flights except some short-haul flights. Aircraft toilets were historically chemical toilets, but many now use a vacuum flush system instead.
A toilet is a piece of sanitary hardware that collects human urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia. In urban areas, flush toilets are usually connected to a sewer system that leads to septic tanks in isolated areas. The waste is known as blackwater and the combined effluent including other sources is sewage. Dry toilets are connected to a pit, removable container, composting chamber, or other storage and treatment device, including urine diversion with a urine-diverting toilet.
A nurse call button is a button or cord found in hospitals and nursing homes, at places where patients are at their most vulnerable, such as beside their bed and in the bathroom. It allows patients in health care settings to alert a nurse or other health care staff member remotely of their need for help. When the button is pressed, a signal alerts staff at the nurse's station, and usually, a nurse or nurse assistant responds to such a call. Some systems also allow the patient to speak directly to the staffer; others simply beep or buzz at the station, requiring a staffer to actually visit the patient's room to determine the patient's needs.
The tapping protocol is an initiative developed by the government of New York City to provide members of the deaf and hard of hearing community, as well as others who are unable to voice, with a means of directly reporting emergencies to 9-1-1 from the streets of New York City.
An electrical burn is a burn that results from electricity passing through the body causing rapid injury. Approximately 1000 deaths per year due to electrical injuries are reported in the United States, with a mortality rate of 3-5%. Electrical burns differ from thermal or chemical burns in that they cause much more subdermal damage. They can exclusively cause surface damage, but more often tissues deeper underneath the skin have been severely damaged. As a result, electrical burns are difficult to accurately diagnose, and many people underestimate the severity of their burn. In extreme cases, electricity can cause shock to the brain, strain to the heart, and injury to other organs.
Accessible housing refers to the construction or modification of housing to enable independent living for persons with disabilities. Accessibility is achieved through architectural design, but also by integrating accessibility features such as modified furniture, shelves and cupboards, or even electronic devices in the home.
Euan's Guide is an accessibility review website based in Edinburgh, Scotland. It gives disabled people the opportunity to rate the accessibility of the places they visit and has been described by author Ian Rankin as 'Trip Advisor with wheels on'. It is a registered charity in Scotland (SC045492).
String is a long flexible structure made from fibers twisted together into a single strand, or from multiple such strands which are in turn twisted together. String is used to tie, bind, or hang other objects. It is also used as a material to make things, such as textiles, and in arts and crafts. String is a simple tool, and its use by humans is known to have been developed tens of thousands of years ago. In Mesoamerica, for example, string was invented some 20,000 to 30,000 years ago, and was made by twisting plant fibers together. String may also be a component in other tools, and in devices as diverse as weapons, musical instruments, and toys.
Glass OS is a version of Google's Android operating system designed for Google Glass. "glass-omap" Tag is used in referring to the modified Android code which can be found inside Kernel Repository.
Emergency sanitation is the management and technical processes required to provide sanitation in emergency situations. Emergency sanitation is required during humanitarian relief operations for refugees, people affected by natural disasters and internally displaced persons. There are three phases of emergency response: Immediate, short term and long term. In the immediate phase, the focus is on managing open defecation, and toilet technologies might include very basic latrines, pit latrines, bucket toilets, container-based toilets, chemical toilets. The short term phase might also involve technologies such as urine-diverting dry toilets, septic tanks, decentralized wastewater systems. Providing handwashing facilities and management of fecal sludge are also part of emergency sanitation.
