  Doctors can and do use arterial blood sampling but usually only when it is absolutely necessary ie. they need an arterial blood sample for arterial blood gas analysis (ABG) to find out how much oxygen and CO2 is in the arterial blood or when they cannot get venous access (for examples in trauma or otherwise seriously ill patients). Venous blood is preferred for number of reasons: - It is easier. Veins are superficial and there are lot of them. If you compress the arm proximally you can see and feel the veins running across the length of the upper limb. If you are taking arterial blood you usually go for the radial artery and you usually have to rely on the pulse you feel (or hear using doppler). Veins also tend to be more tethered if you pick the right spot ie the vein doesn't wiggle away when you try inserting the needle and you don't need to go fishing for it. Veins also have thinner walls which makes it easier to get a needle in. Novices (like myself) may need to use a bit...

In physics, the Planck length, denoted ℓP, is a unit of length that is the distance light travels in one unit of Planck time. It is also the reduced Compton wavelength of a particle with Planck mass. It is equal to 5.72938×10⁻³⁵ m (Lorentz–Heaviside version) or 1.61623×10⁻³⁵ m (Gaussian version). It is a base unit in the system of Planck units, developed by physicist Max Planck. The Planck length can be defined from three fundamental physical constants: the speed of light in a vacuum, the Planck constant, and the gravitational constant. It is the smallest distance about which current, experimentally corroborated, models of physics can make meaningful statements. At such small distances, the conventional laws of macro-physics no longer apply, and even relativistic physics requires special treatment. The smallest possible size for anything in the universe is the Planck Length, which is 1.6 x10 -35 m across. It is impossible to determine the difference between two locations less than one ...

The cricket Snickometer (known as 'snicko' for short) was invented by English Computer Scientist, Allan Plaskett, in the mid-1990s. Snickometer technology was first used in 1999 by Channel 4 in the UK, before being used in India and Australia. The snickometer is composed of a very sensitive microphone located in one of the stumps, connected to an oscilloscope that measures sound waves. When the ball nicks the bat, the oscilliscope trace will pick up the sounds. At the same time, a high speed camera records the ball passing the bat. The oscilliscope trace is then shown alongside slow motion video of the ball passing the bat, and by the shape of the sound wave you can determine whether of not the noise picked up by the microphone coincides with the ball passing the bat, and whether the sound seems to come from the bat hitting the ball or from some other object. This technology is used in televised cricket matches to graphically show the video of the ball passing the bat at the sa...

Apples are a popular and healthy fruit. Apples are easy to cultivate and tailor to certain tastes because of their resilient genetic diversity. They also have antioxidant properties that help protect against cancer-inducing oxidative damage, which can lead to various health problems. The saying “an apple a day keeps the doctor away” has withstood the test of time because of the impressive health profile of apples. But as you bite deep into an apple, you are confronted with something not so sweet in its core: tiny black seeds. Unlike the sweet tang of the fruit, the tiny black seeds are another story. They contain amygdalin, a substance that releases cyanide when it comes into contact with human digestive enzymes. But acute toxicity is rare if you accidentally eat some of the seeds. How cyanide works: Cyanide is a chemical known as one of the deadliest poisons. It has been used in chemical warfare and mass suicide. Many compounds that contain cyanide—called cyanoglycosides—are found in ...

This runny nose is not mucus, but it actually is tears that came from your eyes. Tears are produced by the lacrimal gland or commonly known as your tear gland located just above your eyes. Tears are important as a lubricant and to clean our eyes from particles in the air and are consistently produced by blinking our eyes. That is why when you feel your eyes are dry you are told to blink more. The tears are drained out to our noses through a lacrimal punctum. The lacrimal punctum is located in the inner corner of your eyes at both the upper and bottom eyelids. It is a small hole where your tears are drained to. In normal circumstances, the tears produced are very little and thus you may not notice it as it went into your nose. However, when you are crying you produced an excess of tears, and this tear goes into your nose mixed with the mucus that is already there and produces the snot which you usually have following a cry. A blocked tear duct is a full or partial obstruction (blockage)...

Different formats are used in different job proposals, and knowing about all the formats is good. Biodata: Bio-data stands for Biographical data and is an archaic term for Resume or C.V. In a bio data, the focus is on personal particulars like date of birth, gender, religion, race, nationality, residence, marital status, and the like. A chronological listing of education and experience comes after that. Unlike other formats, a biodata does not have much in terms of formatting and in most cases the format is provided by the institution. This makes it easy to collect data in very sequential manner but this format does not do much in the case of explaining the skills as it is not tailored according to the need of the company although it does prove ample amount of information about one’s skills and talents. A biodata can range from about 1 page to 3 page depending on the quantity of information required by the institute. C.V. (CURRICULUM VITAE): Curriculum Vitae is a Latin word meaning “co...
