ICU

An intensive care unit (ICU), critical care unit (CCU), intensive therapy unit or intensive treatment unit (ITU) is a specialized department used in many countries' hospitals that providesintensive care medicine. Many hospitals also have designated intensive care areas for certain specialities of medicine, as dictated by the needs and available resources of each hospital. The naming is not rigidly standardized.

jets

A fighter aircraft is a military aircraft designed primarily for air-to-air combat with other aircraft, as opposed to a bomber, which is designed primarily to attack ground targets by dropping bombs. Fighters are small, fast, and maneuverable. Many fighters have secondary ground-attack capabilities, and some are dual-roled as fighter-bombers; the term "fighter" is also sometimes used colloquially for dedicated ground-attack aircraft. Fighter aircraft are the primary means by which armed forces gain air superiority over their opponents in battle. Since at least World War II, achieving and maintaining air superiority has been a key component of victory in warfare, particularly conventional warfare between regular armies (as opposed toguerrilla warfare). The purchase, training and maintenance of a fighter fleet represent a very substantial proportion of defense budgets for modern militaries.

Moniter lizard

Monitor lizards also known as bayawak or goannas, genus Varanus, are members of the family Varanidae. Varanus is a group of carnivorous lizards which includes the heaviest living lizard, the Komodo dragon and the crocodile monitor which is the longest lizard in the world. The closest living relatives are the anguid and helodermatid lizards.^[1]

Monitor lizards are generally large reptiles, although some can be as small as 12 centimetres in length. They have long necks, powerful tails and claws, and well-developed limbs. Most species are terrestrial, but arboreal and semi-aquatic monitors are also known. Almost all monitor lizards are carnivorous, although Varanus prasinusand Varanus olivaceus are also known to eat fruit.^[2] They are oviparous, laying from 7 to 37 eggs, which they often cover with soil or protect in a hollow tree stump.^[3]

guitar

The guitar is a musical instrument with ancient roots that adapts readily to a wide variety of musical styles. It typically has six strings, but four-, seven-, eight-, nine-, ten-, eleven-, twelve-,thirteen- and eighteen-string guitars also exist. The size and shape of the neck and the base of the guitar also vary, producing a variety of sounds. The two main types of guitars are the electric guitarand the acoustic guitar (of which the three main types are the classical guitar, the steel-string flattop guitar, and the archtop guitar).

Guitars are recognized as one of the primary instruments in flamenco, jazz, blues, country,mariachi, rock music, and many forms of pop. They can also be a solo classical instrument. Guitars may be played acoustically, where the tone is produced by vibration of the strings and modulated by the hollow body, or they may rely on an amplifier that can electronically manipulate tone. Such electric guitars were introduced in the 1930s, and they have continued to have a profound influence on popular culture

Cats

The cat (Felis catus), also known as the domestic cat or housecat^[5] to distinguish it from other felinesand felids, is a small carnivorous mammal that is valued by humans for its companionship and its ability to hunt vermin and household pests. It has been associated with humans for at least 9,500 years^[6] and is currently the most popular pet in the world.^[7]

A skilled predator, the cat is known to hunt over 1,000 species for food. It can be trained to obey simple commands. Individual cats have also been known to learn on their own to manipulate simple mechanisms, such as doorknobs and toilet handles.^[8] Cats use a variety of vocalizations and types ofbody language for communication, including meowing, purring, trilling, hissing, growling, squeaking,chirping, clicking, and grunting.^[9] They are also bred and shown as registered pedigree pets. This hobby is known as cat fancy.

Until recently the cat was commonly believed to have been domesticated in ancient Egypt, where it was a cult animal.^[10] However, in 2004, a domesticated cat that was buried 9,500 years ago was discovered in Cyprus, and a study in 2007 found that the lines of descent of all house cats probably run through as few as five self-domesticating African Wildcats (Felis silvestris lybica) circa 8000 BC, in the Near East.^[4]
