  The International Space Station is a large spacecraft. It orbits around Earth. It is a home where astronauts live. The space station is also a science lab. Many countries worked together to build it. They also work together to use it. The space station is made of many pieces. The pieces were put together in space by astronauts.  The ISS consists of pressurized modules, external trusses, solar arrays and other components. ISS components have been launched by Russian Proton and Soyuzrockets as well as American Space Shuttles. The space station's orbit is about 220 miles above Earth. NASA and other space agencies uses the station to learn about living and working in space. The first piece of the International Space Station was launched in 1998. A Russian rocket launched that piece. After that, more pieces were added. Two years later, the station was ready for people. The first crew arrived in October 2000. People have lived on the space station ever since. Over time more pieces...

  S ugar has a slight odor, particularly granulated beet sugar. While all species of ants can differentiate between a wide variety of odors, the smelling range differs from a few centimeters to meters. Desert ants can smell sugar from up to 3 meters. the food sources that ants cannot smell from a distance they 'smell' it (contact chemoreception) by touching it. So in a way, all the food they detect, they detect it by smelling. So yes, ants smell (although contact chemoreception is more like taste) the sugar. The ant colonies send scout ants to search for food in various directions, often up to a range of 100 to 200 meters.(Depends on the territorial boundary and time of the year). The scout marches steadily in less circuitous paths initially if it has memories of previous feeder locations. (Ants use visual landmarks, and a stereo-smell system to create an odor map and navigate) Periodically it will halt and look for olfactory cues. It will then take into a more circuitous rando...

The word demolition means destruction, breaking down or removal. Demolition of building is the process of dismantling or destroying of a structure after its life of serviceability by pre-planned and controlled methods. Different steps are involved in the process of demolition of building structures which are: •Surveying •Removal of hazardous materials •Preparation of plan •Safety measures There are two types of demolition methods used for buildings and structures: •Non-explosive demolition •Explosive demolition Non-explosive demolition: It means the demolition of a structure done with some equipment without the use of any explosive. Different equipment’s used for the demolition activity are Excavators and Bulldozers, Wrecking Balls etc Explosive demolition: Implosion Method of Building Demolition, Implosion is the process of demolition of a building using explosives. If the supports of the building are removed, the structure collapses. Using implosion technique, the main supports of th...

  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...

  The first pedometers were mechanical models that worked much like a pendulum clock. They featured tiny moving parts that would move back and forth along with the motion of the body as you walked. Each time your body moved with a step, the tiny parts would trigger a switch that would add one to your step count. Modern pedometers work in a very similar way but are partly electronic. Open one up and you'll find a metal pendulum (a hammer with a weight on one end) wired into an electronic counting circuit by a thin spring. Normally the circuit is open and no electric current flows through it. As you take a step, the hammer swings across and touches a metal contact in the center, completing the circuit and allowing current to flow. The flow of current energizes the circuit and adds one to your step count. As you complete the step, the hammer swings back again (helped by the spring) and the circuit is broken, effectively resetting the pedometer ready for the next step. The pedometer sh...

Tasers and stun guns are built on the same fundamental concept: both employ a less-than-lethal electrical charge to ward off an attack. While both a stun gun and a Taser are considered the same weapon under the law, making them legal to carry in most states, there are some major differences to consider between these two types of self-defense weapons.  A stun gun generates a high-voltage electrical charge between two small prongs;  when this electrical current makes contact with the body, a painful charge is delivered. The amperage, however, is too low to seriously or permanently injure an individual and yet is typically strong enough to briefly immobilize someone, buying you precious seconds to escape unharmed. Hence, this is a generally safe and effective self-defense weapon to employ. A Taser also delivers an electrical charge between two electrodes; however, these electrodes shoot out from a compressed gas cartridge inserted in the Taser, which launches the two prongs up to...

During launching the main thing is all steps of launching are done on time. that's why all say Rocket Science is very tough. The procedures for each launch are written carefully. A single-degree angle more inclination of Rocket can damage the trajectory that it follows. A countdown is a sequence of backward counting to indicate the time remaining before an event is scheduled to occur. The purpose of a countdown is to make sure all the engineers know exactly when liftoff should be, and how much time they have to make last-minute adjustments. The countdowns can start from 72 to 96 hours before launch time. There is a long list of things that have to happen to launch a rocket after it gets to the pad. Fueling, engine gimbal tests, sensor checks, computer startups, etc, etc. There's a certain order these have to go in. A countdown provides the backbone for the planning of all this. Don't think of it so much as "time until launch," but rather "progress through the...

In 2016, three fishermen from the middle eastern country of Oman struck "floating gold" in the form of ambergris, traditionally thought to be whale vomit. (Modern science says the waxy substance is more like a whale gallstone, or whale poop.) Although it sounds pretty repellant, ambergris is actually worth big bucks — the chunk that these guys stumbled upon weighed 176 pounds (80 kilograms) and was allegedly worth nearly $3 million. But why was it so valuable? Ambergris (which comes from a French phrase meaning "gray amber") forms in the intestines of a sperm whale. Scientists have found squid beaks in clumps of ambergris, leading many to surmise the ambergris is something of a protective secretion that protects sperm whales' digestive tracts from the scratching of those hard beaks. Traditionally, scientists believed that whales threw it up because they couldn't digest the substance, but many scientists now lean toward thinking that ambergris is passed out j...

The history of pneumatic tube systems can be traced back to the 1850s. The first operating system was built by engineer Josiah Latimer Clark and went into operation at the London Telegraph Office in 1853. Shorter paths for rapid transport were created: Letters, telegrams and even parcels were put in cylindrical containers and sent through the tubes. Colored markings served as identification for the various shipments. Particularly for the stock market, it was an important and, above all, fast method of communication at that time: if messages were not delivered in a timely manner, speculators ran the risk of losing a fortune. More and more pneumatic tube systems were also used in retail trade, banks, and the chemical and automotive industries – mostly to transmit production samples to laboratories. High quality was ensured. In the course of the 19th and 20th centuries, the air system became established in other cities besides London. Mail was sent by the Prague tube network until 2002 – ...

Red-light systems rely on some sophisticated technology, but conceptually they are very simple. The system includes only three essential elements: One or more cameras. One or more triggers. A computer. In a typical system, cameras are positioned at the corners of an intersection, on poles a few yards high. The cameras point inward, so they can photograph cars driving through the intersection. Generally, a red-light system has cameras at all four corners of an intersection, to photograph cars going in different directions and get pictures from different angles. Some systems use film cameras, but most newer systems use digital cameras. There are a number of trigger technologies, but they all serve the same purpose: They detect when a car has moved past a particular point in the road. Red-light systems typically have two induction-loop triggers positioned under the road near the stop line. The computer is the brains behind the operation. It is wired to the cameras, the triggers and the tr...

  An error, flaw, or fault in any computer software or hardware system. It results in unexpected and unwanted results, causing the system to behave weirdly. Put simply, and it is any fault in the computer system that keeps it from performing what it is intended to do. Most bugs take place because of mistakes caused by developers while creating the code or the design. There could be errors in the components or operating systems used by the program in question. Some bugs could result from errors in translation between languages, resulting in illegible or incorrect code. It can be a subtle bug or can result in a system crash or freezing. Some bugs can cause security issues and enable malicious users to obtain unauthorized access to your system. The term "Computer Bug" may be a relatively new word. But it has been used in the formal engineering world for quite a long time. The concept might date back to 1843 when Ada Lovelace, a UK-based English mathematician, and writer, referre...

 The common sailboat comprises eight essential parts: hull, tiller, rudder, mainsail, mast, boom, jib and keel. The hull is the shell of the boat, which contains all the internal components.   Its symmetrical shape balances the sailboat and reduces drag, or the backward pull caused by friction, as it moves in the water. Inside of the hull in the stern, or back of the boat, is the tiller, which is attached to the rudder in the water.   Think of the tiller as the boat's steering wheel and the rudder as the tire. To maneuver a sailboat to the right, for example, you pull the tiller to the right side of the boat, causing the rudder to alter its direction.  If you think of the tiller as the steering wheel, then the sails and the keel are the engines. The mainsail is the larger sail that captures the bulk of the wind power necessary to propel the sailboat. Its vertical side attaches to the mast, a long upright pole, and its horizontal side secures to the boom, a ...

  Clouds are made up of tiny water droplets called cloud droplets. Groups of cloud droplets form water vapour (gas) or ice crystals.  Water vapour isn’t dense enough to fall to the ground as precipitation. Instead, it rises into the sky and becomes supercooled. Eventually, it condenses (turns to a liquid) around tiny particles of dust in the sky. These tiny particles are called condensation nuclei. It takes billions of these condensed water droplets to form a visible cloud.  When the water molecules are spread out, they aren’t dense enough to feel Earth’s gravity. When the molecules huddle together, they form larger, heavier droplets. Eventually, they become heavy enough to fall to the ground as precipitation.  Cloud seeding involves modifying a cloud’s structure to increase the chance of precipitation. Cloud seeding adds small, ice-like particles to clouds. Usually, silver iodide particles are used.  These particles act as additional condensation nuclei. Unatta...

There are several ways in which plant growth can be gauged, the metrics vary for different types of plants. An apparatus known as an auxanometer measures the increase in plant growth. Some other ways of assessing and measuring the plant growth are – measuring the height of the plant, examining the size and number of the leaves, estimating the rate of growth with that of fresh plants, and detecting the rate of growth with dried plants. An auxanometer is an apparatus for measuring the increase or rate of growth in plants. In the case of an arc-auxanometer, there is a wire fixed with the plant apex on one end and a dead-weight on the other. It passes over a pulley that has a pointer attached to it. When the plant's height increases, the pulley rotates and the pointer moves on a circular scale to directly give the magnitude of growth. The "rate of growth" is a derived measurement obtained by dividing the length of growth measured by the auxanometer, by the time said measureme...
