What does guyliner refer to?

Guyliner is a kohl pencil for men. It's getting popular among men in some western countries after celebrities started sporting it. The most famous examples are Johnny Depp in the Pirates of the Caribbean series, Tobey Maguire in Spiderman 3, and Billie Joe Armstrong, the lead singer of the band Green Day

What's the origin of phrase 'gild the lily'?

William Shakespeare used a similar expression in his play King John: 'To gild refined gold, to paint the lily.. is wasteful and ridiculous excess'. Over the years, the phrase got shortened to just 'gild the lily'. Gild means to cover with a thin layer of gold. Why did Shakespeare refer to the lily? Because it is a beautiful flower, and covering it with gold to make it more beautiful would be unnecessary. So, the phrase came to mean to spoil something which is already beautiful by adding something extra.

What is. A scram shutdown and why it is called so?

SCRAM shutdown is an emergency shutdown of a nuclear reactor by inserting a large number of negative reactions into the system. It is derived from the World War II usage of the term 'Safety control rod axe man' which referred to emergency situations wherein a rope was cut to stop the operations urgently and to limit the damages arising out of continuance of such an operation. The dictionary meaning of scram is to leave a place very quickly, so that one is not caught.

Why is a transformer core always cubical in shape?

It is not true that cores are always cubical. Current Transformers (CTs) and Potential Transformers (PTs) have ring-type cores. Power transformers have cubical cores. The ideal transformer is to have all the magnetic flux produced by one winding linking the other. This is not attained in practical transformers. Flux that does not link both windings is called leakage flux and has the effect of adding an inductance that produces a voltage drop when there is a current. Leakage is affected by the shape of me core and by the arrangement of the windings.To reduce leakage, the core must be compact and the windings close together. (ii) The cores used in the transformer are generally made up of laminated silicon steel with high permeability (to minimize eddy current losses). They are rectangular in shape due to many reasons: i) Their winding requires lesser complexity and, hence, equipment is cheaper; ii) They are robust and need very less maintenance; in) There is a very small inflow of current when switched on and iv) Central fixing is easy Due to these reasons, even though toroidal core is better for smaller constructions and due to lesser external magnetic field interference, rectangular cores are preferred.

What are btl advertisements?

Below-the-line (BTL) advertisements refer to a marketing technique in which non-conventional, non-media route is taken to promote a product or service. Usually, it has a limited target group. It includes promoting through e-mail, SMSes, ringtones, direct mail, MMS, freebies, quizzes on a particular product, free interactive sessions explaining a product, etc. It is different from above-the-line (ATL) ads which take the media route of TV; radio, podcasts, cinema, banners, newspapers, etc.

What is laser photonics fabrication?

Laser photonics fabrication is a branch of physics which deals with the manufacture of devices which deploy lasers to transmit, gather and process information. Typical usage would be in optic fiber cables to move data over long distances and sensors to measure temperature in engineering structures. It's a highly specialized area of study and scientists hope to use this to develop high-speed communication devices.

What is acrolein?

Acrolein, CH2=CH-CHO, is a chemical compound. Its IUPAC name is 2-propenal, and it is the simplest unsaturated aldehyde. It was used as a chemical weapon during World War I. It is, however, not outlawed by the Chemical Weapons Convention. Acrolein is a suspected human carcinogen. In October 2006, researchers found connections between acrolein in the smoke from tobacco cigarettes and the risk of lung cancer.

What is unique about bagdad beach?

Bagdad beach is located on the gulf coast of Mexico, in the eastern state of Tamulipas, near the mouth of the river Rio Grande. Although an isolated area today the place played an important role during the Civil War of America which took place in the early 1860s. The town of Bagdad established around the beach in 1848 was an insignificant port till the beginnings of the civil war in the US. When Lincoln blocked US ports for use by the defiant southern states, which formed into the Confederacy, the latter turned to the neutral Mexico for the use of the seaport at Bagdad for their cotton exports. Because of this, the town of Bagdad boomed and expanded during the Civil War. However, with the defeat of the Confederacy and the subsequent ending of the Civil War, Bagdad too declined. Its port was finally closed when the area was hit by a cyclone in 1889. Now, there are no traces of the port town but the beach there is used for recreation and fishing. It is also the centre of an important festival called the Festival of the Sea.

What is xeriscaping?

The word is derived from the Greek word xeros, meaning dry It refers to landscaping which doesn't require additional water. It uses plants which are suited to the local climate, and practitioners ensure that water doesn't evaporate or run off. Xeriscaping is also referred to as water-conserving landscapes, zeroscaping, drought-tolerant landscaping, and smartscaping. It was developed by the water department of Denver, Colorado.

What is maniole?

Maniole is a place in Zaire, currently called the Democratic Republic of the Congo. The average annual temperature here is about 250 degrees Celsius. From 1967, its currency is Zaore.

What is the 'plum pudding' model of an atom?

The 'plum pudding' model of the atom was proposed by JJ Thomson, who had also discovered the electron. It was put forth before the discovery of the nucleus. According to this model, the atom is a sphere of positive charge, and negatively charged electrons are embedded in it to balance the total positive charge. The electrons are like plums in a pudding. However, this model was discarded when Rutherford performed the famous alpha particle scattering experiment and put forth his model of the atom, which was similar to our solar system, with electrons revolving around a positively charged, dense nucleus.

What is the latur pattern of study?

The Latur pattern of study involves continuous and methodical practice of model question papers months before the board exams. This method was devised by principal Aniruddha Jadhav of Rajarishi Shahu College in Latur, who felt this mechanical methodology of continuous study helps students in providing point-topoint answers to questions which could be expected in the examination. This methodology, however, has been lambasted by educationists who consider it a tool to gain temporary advantage that does not aim to prepare them for advanced learning.

What is molecular phylogeny?

In Greek, phyle means tribe, and genesis means birth. Molecular phylogeny is the attempt to reconstruct the lineage of species through study of amino acid sequences in fossils. The result of a molecular phylogenetic analysis is expressed in a phylogenetic tree.

Who was king frederic ii?

Frederic 11 (1712-1786) was the king of Prussia during 1740-1786. During his reign, Prussia prospered greatly and doubled in area. For his military prowess and welfare orientation, he was affectionately called Frederic the Great by his countrymen. He was the son of Frederic William-I and Sophie Dorothia von Hannover. As a crown prince, he disliked military affairs, but as soon as he became the king, he exhibited great military genius by waging and winning many wars against neighbouring countries like Austria, Russia, and France. Declaring himself to be the first servant of his people, he achieved remarkable economic and social development of Prussia, by taking several progressive and reformatory steps. He believed in enlightened absolutism, showed great religious tolerance, and fostered the arts, sciences, and education. Besides being a powerful and benevolent monarch, he was deeply interested in philosophy and music. He authored books on a variety of subjects, and befriended intellectuals like Voltaire, D'Alembert, and Lagrange. As he was childless, he chose his nephew, Frederic William-II, as his Successor.

Who invented shorthand?

Shorthand is believed to have been invented by Tiro, a slave of Marcus Tullius Cicero, to keep pace with the speeches his master delivered. Cicero (January 3,106 BC — December 7,43 BC), a statesman, lawyer, political theorist, and philosopher, is considered one of Rome's greatest orators. His political speeches are well known, and he delivered these in an elaborate and flowery style, which came to be known as the Ciceronian rhetorical style. Tiro perfected a system of Latin shorthand, which served to"preserve the speeches. The Tironian notes consisted of word stem abbreviations (notae) and word ending abbreviations (titulae). The original Tironian notes consisted of about 4,000 signs but the number gradually increased to 13,000. After Cicero's death, Tiro published many of Cicero's speeches. He is also credited with writing a biography of Cicero, a book on grammar and a book on philosophical questions.

What is a lame duck session of parliament?

A lame duck session is conducted after election of new members but before they are installed. Hence, in such a session participants vote for the last time as elected officials because of their failure to get reelected or because they are retiring voluntarily. In the US, it is a term for a person or legislature that continues to hold office after losing an election. The practice in the US of holding presidential elections in November with the winner taking office only in January means that often there are lame duck Presidents.

What is the coriolis force?

The Coriolis Force is an important element in meteorology. It" acts on the atmosphere and is caused by the rotation of Earth, which rotates on its own axis from west to east with an angular velocity of 15 degree per hour and gives rise to an apparent force called Coriolis Force or geostrophic force. It acts at right angles to the wind vector, to the right in the northern hemisphere and to the left in the southern hemisphere. It was first postulated by a scientist named Coriolis.

What are t-rays?

T-rays stand for terahertz radiation. It is used to scan airline passengers for explosives and illegal drugs. The rays are particularly effective, as they can see through clothing, paper, leather, plastic, wood, and ceramics. They don't penetrate as well as x-rays, but they also don't damage living tissue. They can read spectroscopic signatures, detecting the difference between, say, hair gel and an explosive.

What is the scopes trial?

The Scopes Trial brought about a prosecution in 1925 in Dayton, Tennessee. The prosecution was of a high school biology teacher who taught the theory of evolution. The teacher, John T Scopes, was accused of having violated the Butler Act, a Tennessee law that forbade the teaching of the theory of evolution in public schools because it contradicted the account of creation in the Bible. The press dubbed it the Monkey Trial because, according to popular belief, evolution meant that humans had evolved from monkeys. The defence argued for the scientific validity of evolution and against the constitutionality of the Butler Act, but it did not deny that Scopes had broken the law. He was convicted and fined $100, but the verdict was later reversed on technical grounds by the Supreme Court. The Butler Act remained on the books until 1967.

When was the kite invented?

The exact date and origin of the kite is not known but it is believed that they were flown in China more than 2,000 years ago. The earliest written account' of kite flying was in about 200 BC when the Chinese general Han Hsin of the Han dynasty flew a kite over the walls of a city he was attacking to measure how far his army would have to tunnel to reach past the defences. Calculating this distance correctly, his troops reached the inside of the city surprised their enemy, and were victorious. Kite flying was eventually spread by traders from China to Korea, and across Asia to India.

Which country has the highest male-female ratio?

The male-female ratio is the proportion of males to females in a given population at a specified stage in life e.g. at conception, at birth and at any chosen stage between birth and death. This is usually expressed as the number of males per 100 females. Qatar has the highest ratio with 187 males to 100 females. However, the ratio for the entire world population is 101 males to 100 females. Qatar's high male-female ratio is mainly on account of large immigrant labourers staying without families. In Qatar, the ratio goes up to 284 males to 100 females for the population above 65 years on account of aging male immigrants and comparatively higher average mortality rate for females.

Why is earthing necessary for electrical appliances?

As it's a safety factor, earthing is essential and mandatory. It's an electrical connection between the exposed metallic parts of an electrical appliance or installation and the earth, regarded to have zero potential. Proper earthing provides an alternative and easy path for leakage or faulty current to flow. It ensures that any exposed conductive part of the appliance does not reach a dangerous level of potential or voltage that endangers the life of the user. A proper earthing system should have least electrical resistance, good corrosion resistance and ability of dissipating high faulty current.

What is ethical fashion?

Ethical fashion involves taking into consideration the various people involved in making a piece of clothing. For instance, even as one buys a pair of jeans, not many think about the farmers who grew the cotton that went into creating the material, the workers (mainly from poor countries) who helped sew the jeans, the various chemicals used on it and the economics of production. Ethical fashion involves creating clothes that don't adversely impact people or the environment.

What is the fenian movement?

The Fenian Movement or Fenians is a secret revolutionary society organized in 1858 in Ireland and the United States to achieve Irish independence from England by force. It was known variously as the Fenian Brotherhood, Fenian Society, Irish Republican Brotherhood, and Irish-American Brotherhood. The famine of the 1840s brought to a crisis Irish discontent with English rule, culminating in the abortive Young Ireland uprising of 1848, led by William Snpth O'Brien.

What is project blue beam?

Project Blue Beam is a conspiracy theory about a supposed project whose purpose is to create an artificial Second Coming, in order to control people. As per the alleged theory, the new world order's purpose is: 1. To abolish all Christian and traditional religions in order to replace them with a one-world religion based on the cult of man. 2. To abolish all national identities and national pride in order to establish a world identity and a world pride. 3. To abolish the family as known today in order to replace them with individuals all working for the glory of the new one-world government. 4. To destroy all individual artistic and scientific creativity to implement a one-world government, one-mindset.

What is the priory of sion?

The Priory of Sion is a very obscure group whose presence has not been established with concrete evidence. Papers relating to their existence were found in 1975 at Paris Bibliothhque Nationale, which named Da Vinci and Isaac Newton among its Grand Masters. According to the most popular theory, it is believed that the priory started out as an administrative wing of the Knights Templar. They had something (though it's not very clear what it is) that gave them immense power and authority, even over the Pope. The most accepted answer among scholars is that they had documents written in the years Christ walked the Earth, which gave evidence that He was married to Mary Magdalene.

What is dragon's triangle?

The Dragon's Triangle is at the polar opposite of the Bermuda Triangle. Both triangles are located at 35 degrees west and 35 degrees east latitude and longitude which means if you were to start out at the Bermuda Triangle and travel straight through the centre of the Earth, you would come out at the Dragon's Triangle. This dangerous ocean triangle has reportedly claimed hundreds, if not thousands, of ships, airplanes, and submarines since it was first written about in the 13th century. This is a result of bad oceanic conditions or maybe something more mysterious.

What is bear bile farming?

The Chinese practice of extracting bile from captive bears for use in traditional medicinal products is called bile farming. Many animal welfare groups decry this as inhumane. Bear bile has been prized in the traditional Chinese medicine community for thousands of years. It's got a reputation as being a sort of wonder drug, and its active ingredient, ursodeoxycholic acid (UDCA), is believed to cure a number of ailments — everything from cardiac illness to impotence, according to the Humane Society of the United States. As an unhappy consequence, more than 10,000 bears are currently held in captivity on bear bile farms in China today, according to the Animals Asia Foundation.

What is guano?

Guano is accumulated dung or excrement and remains of seabirds, bats and seals found along certain coastal areas and caves. It's found mainly on the coastal islands of Peru, Africa, Chile and the West Indies. It contains about 6% phosphorus, 9% nitrogen, 2% potassium and moisture. Guano is found mixed with feathers and bones and used mainly as a fertilizer. Bird guano is comparatively a better fertilizer than bat guano found in caves and seal guano, accumulated on islands off north-western Peru. Since the global reserves of phosphorus will only last another 30 years, the use of guano as a fertilizer is gaining importance.

What is coriolis force?

Coriolis Force occurs whenever a rotating body moves along a curved path. Hence, two rotary movements (rotation on its axis and precession about a line) are necessary conditions. Whenever a vehicle in motion takes a turn, the wheels rotate about their axis and the entire vehicle, including the wheels, goes round the bend, resulting in Coriolis Force. This is the most common occurrence of this force.

What is the principle of a voltage stabilizer?

A voltage stabilizer is an electro cal appliance used to feed constant voltage current to costly electrical gadgets like ACs and computers, and protects them from damage due to voltage fluctuations. A voltage stabilizer works on the principle of a transformer, where the input current is connected to primary windings and output is received from secondary windings. Whenever there is a drop in incoming voltage, it activates electromagnetic relays which add to more number of turns in the secondary winding, thus giving higher voltage which compensates for loss in output voltage due to drop in incoming voltage. When there is rise in the incoming voltage, the reverse happens, and, thus, the voltage at the output side remains almost unchanged.

What is haarp?

HAARP is an acronym for the High Frequency Active Auroral Research Program, a research initiative aimed at studying the effect on the performance of communication, navigation and surveillance systems by simulated heating of the ionosphere. It was started in 1993 and is expected to continue till 2013. It is defence oriented and toided by various US defence agencies, including the air force and the navy. A powerful HF signal is transmitted to heat a limited area of the ionosphere for a specified time. Scientists then record the effects of temporarily altered conditions through advanced instruments. It's been at the centre of controversies, with some organizations claiming that the transmission antennae may be used as weapons.

What is argemone oil?

Argemone oil is extracted from argemone seeds. It is mixed with sunflower oil and sesame oil to raise their quantity. Consumption of this oil leads to health disorders among children. To avoid this, we must check the contents of the cooking oil. Many oil brands mention 'no argemone oil' on their packs.

What is switchgrass?

Switchgrass, known in Botany as Panicum Virgatum L., is the perennial tall grass found in the prairies of North America and many parts of Mexico. Its height varies from 5 ft to 12 ft, and the diameter of its stem at ground level is about 20 inches. It can grow easily even in poor-quality soil, with low requirement of inputs like fertilisers, and can tolerate hostile environmental conditions, including floods and drought. The grass has both main roots that penetrate deep into the soil, and many temporary fine roots, which enable it to conserve the soil in which it grows, and make the soil nutritionally rich. Therefore, switchgrass has been grown traditionally for soil conservation and to serve as fodder. Since the 1990s, interest in this plant has increased because it generates a lot of biomass, which can be used for producing fibre, ethanol, electricity, and other chemicals.

Which compound is used in making bulletproof jackets?

Bulletproof jackets were being manufactured with ballistic nylon material till the 1970s. In 1965, a compound — poly- paraphenyleneterephthalamide — was invented with the brand name Kevlar. This is a liquid polymer which can be spun into fibre and woven into cloth. Kevlar was originally developed for tyres and, later, for ropes, gaskets and various parts of planes and boats. The efficacy of the material led to its usage for the manufacture of bulletproof jackets. Another product with the brand name Spectra was developed in 1989 as a competitor for Kevlar. Spectra is a polyethylene fibre originally developed as a sail cloth and, later, used to make stronger and lighter non-woven material for bulletproof jackets.

Who invented the board game monopoly?

Charles Darrow, a US citizen, invented Monopoly in 1931, during the Great Depression. Out of work, Darrow earned a living doing part time jobs and inventing puzzles and games, to sell to toy-makers. With some difficulty, he sold Monopoly to Parker Brothers on a royalty basis. The game sold so well that Darrow soon became a millionaire. The original game had properties named after streets, hotels, etc. in Atlantic City, where Darrow lived. In India, we initially played with the British version, containing London-based names like Old Kent Road and Piccadilly. Later, an Indian version was released; it was called Trade and featured, sites in Mumbai, such as Churchgate Station and Byculla.

What is maniole?

The average temperature in Maniole is perhaps 25 degrees Celsius (Aug. 24).

Who is a wardriver?

A wardriver is someone who accesses an unsecured wireless connection through a PDA or laptop in a moving vehicle. It's derived from the word wardialling from the film WarGames. Other related concepts are warbiking (accessing a wi-fi connection on a motorbike or bicycle) and warwalking/ jogging (doing the same while on foot). While there are several softwares to enable wardriving, they can be easily misused as well. In India, terror e-mails were sent by wardrivers who accessed anunprotected wireless connection.

What are the cod wars?

The three Icelandic Cod Wars that took place in 1958, 1973 and 1975 were precipitated by concerns on the part of Iceland that the stocks of cod fish were being seriously depleted by over-fishing. With timber, agriculture, fuel or mineral deposits being the few natural resources in Iceland, the country relies heavily on its stocks of cod fish and the Cod Wars have been vital in protecting this industry In 1958, the first Icelandic Cod War took place after it extended its fishing limits from 4 miles to 12 miles off Iceland's coast. In 1972, Iceland further extended its limits to a 50-mile radius which prompted a hostile response from other nations, not least Britain, and the second war took place. An agreement was reached in 1973, when Britain agreed to limit fishing for cod to designated areas within the 50-mile radius. What further instigated the third war, apart from the expiry of the agreement made at the end of the second war, was Iceland's move to extend the radius to 200 miles.

What is the karakoram highway?

The Karakoram Highway (KH) or Friendship Highway or N35 connects the Kashgar town in Xinjiang region in China to Havelian (Abbottabad district) in Pakistan, which extends further to the junction of Grand Trunk (GT) Road at Hasan Abdal in Pakistan. KH is the world's highest paved international road constructed across the Karakoram mountain range and through the Khunjerab Pass located at an altitude of 4,877 metres. It was built by the governments of China and Pakistan between 1966 and 1986. KH has given a boost to adventure tourism by giving easier access to high mountains, five major lakes and glaciers like Baltoro for mountaineers and adventure-seekers. KH is sometimes referred to as the Ninth Wonder of the World because of its high altitude and difficulties encountered in construction.

What is magic acid?

Magic Acid, H2S03F+, is one of the inorganic superacids. This extremely strong acid has a pKa of 20 and is strong enough to protonate saturated alkanes to form carbonium ions. Magic Acid is made by mixing antimonypentafluoride (SbF55) and fluorosulphonic acid. It is considered a superacid and is called Magic Acid because of its strength. It can dissolve a wax candle, something that even sulphuric acid cannot do.

What is enneagram personality?

The term enneagram is derived from two Greek words, ennea (nine) and grammos (something written or drawn). The Enneagram is a ninepointed figure inscribed in a circle. The meaning of the symbol itself, together with the personality types organized around the nine points, convey a system of knowledge about nine distinct but interrelated personality types, or nine ways of seeing and experiencing the world. The enneagram of personality is generally presented as a psycho-spiritual system for mapping the nine possible personalities, like nine facets of a stone that develop through the natural growth of the human psyche.

What is the bossa nova?

The Bossa Nova is a type of Brazil- ian music system, innovated in 1958. The system merges the samba rhythms, typical to traditional Brazilian dance music, with the melodies of jazz. Catching the fancy of college students, this system of fusion reached the peak of popularity between 1958 and 1963. The system contributed a lot of popular songs to the standard set of jazz compositions of that era. Later, Bossa Nova underwent many modifications and enhancements giving rise to several variants. In Europe, electronic music was incorporated in Bossa Nova, producing a new musical system called Bossa Electrica. The term Bossa Nova in Portuguese language means 'new way'.

What is confessionalism?

The word confessionalism occurs in the fields of religion, politics and poetry, each having a different meaning. In religion, particularly in Christianity, confessionalism refers to the belief that a truly religious person should accept the entire teaching of the religion, both its values and rituals. It lays a lot of emphasis on religious dogma and does not allow for alternative interpretations of the religion. Non-confessionalists, on the other hand, believe that shared values and religious spirit and religious experience are more important than ritual and dogma of a religion. In the field of politics, it signifies a system of government which apportions seats in its legislature and various government jobs to different groups of people strictly based on demographic composition. For instance, the government of Lebanon is based on the confessionalist model. In poetry, confessionalism refers to a movement, which became popular in the 1950s and '60s. In this form of poetry, the work focuses on intimate details of the poet's life, however unpleasant they may be.

Why is a bmw car also kmrwn as a beemer?

The terms Bimmer, Beemer or Beamer refer to BMW vehicles. However, Bimmer is the correct term for BMW cars while Beemer and Beamer are used for BMW motorcycles. Why all these different terms? BMW started big in motorcycles and was very active in motorsports then. One of its biggest competitors at the racing track was BSA, which was. also a big name in motorcycles.

What is the inert pair effect?

To understand the inert pair effect, we need to understand the periodic table. There are some inherent properties of elements in the table. The inert pair effect is nothing but the extra stability concept. Generally p-block elements belonging to 3A, 4A, 5A, 6A, etc. show variable valency. For example, Sn element of group 4A shows +4 and +2 oxidation state. The higher oxidation stats is called the group number oxidation state and +2 oxidation state is called the lower oxidation state which is equal to Group-2. Consider the configuration, if the electrons are lost from ns and np level, then group oxidation state of +4 is obtained while np electrons are only lost then +2 oxidation state is obtained due to its extra stability of ns electrons which are called inert pair. The effect is the inert pair effect.

What is an amoled display?

The term AMOLED stands for Active Matrix Organic Light Emitting Diode/ Device/ Display. An Organic Light Emitting Diode (OLED), also Light Emitting Polymer (LEP) and Organic Electro Luminescence (OEL), is any Light Emitting Diode (LED) whose emissive electroluminescent layer is composed of a film of organic compounds.

The resulting matrix of pixels can emit light of different colours.

Does an electric field affect plant growth?

Yes, an electric field affects plant growth. In the presence of an electric field, the height of the stem and the length of the roots are more than those without an electric field. The change in growth rate depends on electric field, temperature and humidity. Experiments show that if an electric field intensity of 25 kv/m is applied and temperature and humidity are controlled at 28 degree Celsius and 65% respectively, then the height of the stem increases by 24% and length of roots by 33 %.

What is air hunger?

Air hunger is the urge to brythe, which is caused by the deytion of high levels of carbon dioxide in the blood by sensors in the carotid sinus. It is one of the body's homeostatic mechanisms to ensure proper oxygenation. Air hunger may be caused by insufficient pulmonary minute ventilation, a sustained breath-hold constriction of the alveoli of the lungs, as in asthma, or high ambient levels of carbon dioxide in the air. Air hunger can be very distressing and triggers strong reactions to restore breathing. Air hunger is caused due to excess of carbon dioxide rather than lack of oxygen.

What is einstein's rule of 72?

The rule of 72 is a rule of thumb (credited to Albert Einstein) that investors use to approximate the time it takes for money to double at a given rate of return. It states that if you divide the number 72 by any given rate of return, the answer you get is the time it takes for money to double at that given interest rate (assuming you can get the same rate each year and it is compounded annually). For example, if you earn 10% on your money it would double in 7.2 years (72 divided by 10 = 7.2). The value 72 is a convenient choice of numerator, since it has many small divisors: 1, 2, 3, 4, 6, 8, 9, and 12. It provides a good approximation for annual compounding, and for compounding at typical rates (from 6% to 10%). The approximations are less accurate at higher interest rates.

What is concentrated solar power plant?

Concentrated solar power plants (CSPs) generate electricity by using the sun's energy to convert water into steam to run turbines connected to generators. Such a power plant consists of large sun-tracking mirrors (heliostats) to focus sunlight on a receiver at the top of a tower. The receiver uses solar power to heat up a heat-transfer fluid to generate steam which, in turn, is used in a convection turbine generator to produce electricity Such plants are similar to those of coal or gas-based plants. Nowadays, molten ammonium nitrate salt is used as a heat-transfer fluid, which can store heat inside it. Hence, these plants can even work at night or on a cloudy day

What is a false vacuum?

False vacuum and true vacuum form a metastable system. Metastable state is a state which does not change with time but is susceptible to falling into lower-energy states with only slight interaction. It is analogous to being at the bottom of a small valley when there is a deeper valley close by. True vacuum is the name applied to a condition of the true lowest energy state of the vacuum. False vacuum refers to a condition with an elevated vacuum energy density. The two conditions are separated by some energy barrier — which is why they form a metastable system. If the current universe is in a state of false vacuum, it is conceivable that some experiment would concentrate enough energy into a small enough place to coax the vacuum over the energy barrier and into the true vacuum state. This could perhaps be catastrophic.

What is chargafts rule of base equivalence?

Deoxyribonucleic acid (DNA) is the genetic material found in the chromosomes of all animals and plants. It is made up of only four types of organic nitrogenous bases: adenine (A), guanine (G), thymine (T) and cytosine (C). Of these, A and G are the purines and T and C are the pyrimidines. Chargaff gave the base pairing rule or the rule of base equivalence which states that only one purine can combine with one. pyrimidine. That means A can combine with T and G with C. Two purines or two pyrimidines cannot combine with each other; if they do so, there will be a sudden change in the characteristic of an organism. This sudden change is called mutation.

Green Laser Beam Light

What danger do lazer pointers pose to aircraft?

Sydney airport flight - Beams from four green lasers, which appeared to come from an area just southwest of the city, were directed at planes for 15 minutes late Saturday, in what officials labeled a "coordinated attack."

What could a lazer pointer do? You cant point the thing into a cockpit from the ground so what could a beam of light possibly do?
If you say that the light will blind the pilot what about when the plane flies towards the sun on the horizon.

The type of laser pointer which is currently making all the fuss in the news is the green laser pointers which are classified as class 3A (or 3R in some states).

These laser pointers are easily attainable in shops and over the internet because they do not present much risk to people. If you point them at people, their blink reflex means that they shut their eyes before they sustain permanent eye damage. These laser pointers are no different (in terms of potential risk) than the red laser pointers which have been in use by the public for years. The only difference is that the green light has a shorter wavelength than red light which means that the light scatters of particles in the air so we can see the beam.

These laser pointers do not pose any risk to an aircraft itself. However, you could argue that they can pose a risk as they may distract a pilot (although many landings are done on autopilot anyway).

I think the real reason why they've become an issue is that you can see the beam (unlike the red ones were used to). They aren't any more dangerous than the red ones but people don't understand the differences between different types of lasers.

It should be noted that there are other types of lasers which are also visible in the air (usually still green but higher powered). These are much more expensive so the average teenager mucking around couldn't afford one and they're much more difficult to get.

what advantage is realize by use of a short wavelength light beam (Green versus Red)?

Compact disc recording media uses laser to read back the information that they contain, what advantage is realize by use of a short wavelength light beam (Green versus Red).

That would only work if the light frequency is used as the carrier. It is not. Regardless of using a red or green laser you would still get 1 bit per pulse and the amount of data transfered is dependant on the speed of laser modulation and not on the wavelength of the laser.

I would assume that a shorter wavelength would actually mean a higher density of information on the storage medium and not necessarily higher transfer rates.

Edit:.. Bah.. InPhase E beat me to it.

Principles of Laser Spectroscopy and Quantum Optics $40 Principles of Laser Spectroscopy and Quantum Optics is an essential textbook for graduate students studying the interaction of optical fields with atoms. It also serves as an ideal reference text for researchers working in the fields of laser spectroscopy and quantum optics.The book provides a rigorous introduction to the prototypical problems of radiation fields interacting with two- and three-level atomic systems. It examines the interaction of radiation with both atomic vapors and condensed matter systems, the density matrix and the Bloch vector, and applications involving linear absorption and saturation spectroscopy. Other topics include hole burning, dark states, slow light, and coherent transient spectroscopy, as well as atom optics and atom interferometry. In the second half of the text, the authors consider applications in which the radiation field is quantized. Topics include spontaneous decay, optical pumping, sub-Doppler laser cooling, the Heisenberg equations of motion for atomic and field operators, and light scattering by atoms in both weak and strong external fields. The concluding chapter offers methods for creating entangled and spin-squeezed states of matter.Instructors can create a one-semester course based on this book by combining the introductory chapters with a selection of the more advanced material. A solutions manual is available to teachers.Rigorous introduction to the interaction of optical fields with atomsApplications include linear and nonlinear spectroscopy, dark states, and slow lightExtensive chapter on atom optics and atom interferometryConclusion explores entangled and spin-squeezed states of matterSolutions manual (available only to teachers)Paul R.

LASER AND NON-LINEAR OPTICS BY IMRAN AZIZ.flv

differentiate the laser fiber optics communication system over copper wire system?

FIBER OPTICS IS USED ON LONGWIRES FROM CENTRAL OFFICE TO CENTRAL OFFICE ! WHERE COPPER WIRES ARE USED FOR DISTRIBUTION FROM THE CENTRAL OFFICE TO THE USER!

FIBER OPTICS IS USED BY MAJOR COOPERATIONS IN CONNECTING THEIR SWITCH TO THE MAIN LINE. AND ON CERTAIN LEASE LINES CONNECTIONS AGAIN BY MAJOR COOPERATIONS USING A WIDE BANDWITH WHICH TODAY IS USUALLY DIGITAL DATA, BUT CAN EASILY BE TELEVISION FEED! THRU LEASE LINES.

FIBER OPTICS IS AT A MAJOR DATA TRANSMISSION LEVEL OR IN INDUSTRY IT IS USED WHERE MAGNETIC INFLUENCES LIKE WELDING IN SHIPBUILDING INTERFERE WITH DATA SO THEY USE FIBRE OPTICS EXCLUSIVELY ALMOST NO COPPER WIRE AROUND THE NUMERIC CONTROL DATA LINES IN THE AUTOMATIC WELDING AND CONTROLS FOR CUTTING STEEL AND WELDING SHIPS TOGETHER!

THATS ABOUT IT ALSO IN THE AIRFRAME BUILDING INDUSTRY! WHERE MAGNETIC INFLUENCE MESSES UP THE NCR EQUIPMENT!

HOPE THAT HELPS YOU OUR SOMEWHAT!

HAVE A GOOD DAY!

hi can you tell me if green lasers (100mw) are legal in the uk?

for example deal extreme sell them.

I believe that they are legal as long as you use them for what they were intended. If you use them for pointing at aircraft or cars at night, then that's not legal.

DealExtreme......Good for Tamper Data?

I just ordered a 100MW Green Laser from Deal Extreme, but they did not give me the thing, I have tried contacting them but they don't answer, i want to do revenge! so is it safe to use Tamper Data (Gonna use proxy)?

You should try to contact a lawyer to help you to suit them.

Internet revenge won't solve your problem even that it works.
