Resistance

Electrical resistance is a compute of the degree to which an object opposes an electric current through it. The SI unit of electrical resistance is the ohm. Its reciprocal quantity is electrical conductance calculated in siemens. Electrical resistance shares some conceptual parallels with the mechanical notion of friction.

The resistance of an object determines the amount of current through the object for a known voltage across the object I=V/R, where R is the resistance of the object, measured in ohms, equivalent to J•s/C2, V is the voltage across the object, measured in volts, I is the current through the object, measured in amperes. In metals, the Fermi level lies in the conduction band giving rise to free transfer electrons. However, in semiconductors the position of the fermi level is within the band gap, closely half way between the conduction band minimum and valence band maximum for intrinsic semiconductors.

Journalism Basics

Journalism is a concrete, professionally oriented major that involves gathering, interpreting, distilling, and other reporting information to the general audiences through a variety of media means. Journalism majors learn about every possible kind of Journalism.

That's not all, though. In addition to dedicated training in writing, editing, and reporting, Journalism wants a working knowledge of history, culture, and current events. You'll more than likely be required to take up a broad range of courses that runs the range from statistics to the hard sciences to economics to history. There would also be a lot of haughty talk about professional ethics and civic responsibility too - and you'll be tested on it. To top it all off, you'll perhaps work on the university newspaper or radio station, or possibly complete an internship with a magazine or a mass media conglomerate.

Rose perfumes

Rose perfumes are prepared from attar of roses or rose oil, which is a combination of volatile essential oils, obtained by steam-distilling the trampled petals of roses. The method originated in Persia then spread through Arabia and India, but nowadays about 70% to 80% of production is in the Rose Valley near Kazan in Bulgaria, with some production in Qamsar in Iran and Germany. The Kaaba in Mecca is yearly washed by the Iranian rose water from Qamsar. In Bulgaria, Iran and Germany, damask roses are used. In the French rose oil industry Rosa centifolia is used. The oil, pale yellow or yellow-grey in color, is sometimes called 'Rose Absolute' oil to differentiate it from watery versions. The weight of oil extracted is about one three-thousandth to one six-thousandth of the weight of the flowers; for example, about 2,000 flowers are necessary to produce one gram of oil.

Trams

Electric-powered trams were first successfully experienced in service in Richmond, Virginia, in 1888, in the Richmond Union Passenger Railway built by Frank J. Sprague. There were earlier saleable installations of electric streetcars, including one in Berlin, as early as 1881 by Werner von Siemens and the company that still bears his name, and also one in Saint Petersburg, Russia, made-up and tested by Fyodor Pirotsky in 1880. Another was by John Joseph Wright, brother of the celebrated mining entrepreneur Whitaker Wright, in Toronto in 1883.
The earlier installations, however, proved difficult and/or variable. Siemens' line, for example, provided power through a live rail and a return rail, like a model train setup, limiting the voltage that could be used, and providing unwanted stimulation to people and animals crossing the tracks. Siemens later planned his own method of current collection, this time from an overhead wire, called the bow collector. Once this had been developed his cars became equal to, if not superior than, any of Sprague's cars. The first electric interurban line connecting St. Catherine’s and Thorold, Ontario was operated in 1887, and was measured quite successful at the time. While this line proved quite versatile as one of the earliest fully functional electric streetcar installations, it still required horse-drawn carry while hiking the Niagara Escarpment and for two months of the winter when hydroelectricity was not available. This line continuous service in its original form well into the 1950s.

Hobbies

A hobby-horse was a wood or wickerwork toy made to be ride just like the actual hobby. From this game the appearance to ride one's hobby-horse, meaning to follow a favourite pastime, and in turn, hobby in the modern sense of recreation.Hobbies are practised for interest and satisfaction, rather than financial reward. Examples include collecting, creative and artistic pursuits, building, tinkering, sports and adult education. Engaging in a hobby can lead to acquiring significant skill, knowledge, and experience.
However, personal realization is the aim.What are hobbies for some people are professions for others, a game tester may enjoy cooking as a hobby, while a qualified cheif might enjoy playing computer games. Generally speaking, the person who does something for fun, not remuneration, is called an recreational as distinct from a professional.An important determinant of what is considered a hobby, as individual from a profession is probably.

Indicator

Dial indicators are instruments used to correctly measure a small distance. They may also be known as a Dial gauge, Dial Test Indicator, or as a clock. They are named so because the measurement results are displayed in a overstated way by means of a dial. They may be used to check the dissimilarity in tolerance during the check process of a machined part, measure the deflection of a beam or ring under laboratory conditions, as well as many other situations where a small measurement needs to be registered or indicated.
An economic indicator is a statistic concerning the economy. The lighting system of a motor vehicle consists of lighting and signaling procedure mounted or integrated to the front, sides and rear of the vehicle. The purpose of this system is to present illumination for the driver to operate the vehicle safely after dark, to increase the visibility of the vehicle, and to display information about the vehicle's presence, position, size, direction of travel, and driver's intentions concerning direction and speed of travel.

Beach volleyball

Beach volleyball is an Olympic group sport played on sand. Two teams, positioned on either side of a net which divides rectangular court, hit volleyball, usually using the hands or arms.
It is evolved from indoor volleyball, and the two sports remain very similar: a team scores points by foundation the ball on the opponents' court, or when the opposing team commits a fault teams can contact the ball no more than three times before the ball crosses the net; and consecutive contacts must be made by unlike players. The most important differences between beach and indoor volleyball are the playing surface, and the team size. There are many minor differences as well, including each half of the court actions 8 by 8 meters.
If a jamming player touches the ball, but it continues onto his side of the net, the block counts as the first contact. Open-hand dinks, where a player uses his or her finger tips to redirect the ball into the opponent's court, are banned. It is legal to cross under the net as long as doing so does not hamper with the opponents' attempt to play the ball. Players are not necessary to rotate positions; they must alternate check, but there are no rotation errors.

Papaya

The papaya is a fruit of the tree. It is a small tree, the single stem growing from 5 to 10 m tall, with spirally set leaves confined to the top of the trunk, the lower trunk is obviously scarred where leaves and fruit were borne. The leaves are large, 50-70 cm width, deeply palmately lobed with 7 lobes. The tree is typically unbranched if unlopped. The flowers are similar in shape to the flowers of the Plumeria but are much slighter and wax like. They appear on the axils of the leaves, maturing into the large 15-45 cm long and 10-30 cm diameter fruit. The fruit is ripe when it feels soft and its skin has attained amber to orange hue. The fruit's taste is vaguely similar to pineapple and peach, although much milder without the tartness, creamier, and more fragrant, with a texture of a little over-ripened cantaloupe.
The primary use of the papaya is as an safe to eat fruit. The ripe fruit is generally eaten raw, without the skin or seeds. The unripe green fruit of papaya can be eaten ripe, usually in curries, salads and stews.

Energy meter

An electric meter or energy meter is a machine that measures the amount of electrical energy supplied to a residence or business. These are customers of an electric company.
The most common type is more accurately known as a (kilo) watt-hour meter or a joule meter. They may also record other variables including the time, when the electricity was used. Modern electricity meters operate by continuously measuring the instantaneous voltage and current (amperes) and finding the product of these to give direct electrical power (watts) which is then integrated against time to give energy used (joules, kilowatt-hours etc). The meters fall into two essential categories, electromechanical and electronic. The type of meter described commonly used on a single-phase AC supply. Different phase of meter configurations use additional voltage and current coils. The most general type of electricity meter is the electromechanical induction meter.

The result in cricket

If the team that bats last has all of its batsmen dismissed before it can reach the run total of the differing team, it is said to have lost by (n) runs. If however, the team that bats last exceeds the opposing team's run total before its batsmen are dismissed, it is said to have win by (n) wickets, where (n) is the difference between the number of wickets conceded and 10.If, in a two-innings-a-side match, one team's combined first and second innings total fails to reach its opponent's first innings total, there is no need for the opposing team to bat again and it is said to have won by an innings and (n) runs, where (n) is the variation between the two teams' totals.

If all the batsmen of the team batting last are dismissed with the scores closely equal then the match is a tie; ties are very rare in matches of two innings a side. In the traditional form of the game, if the time allotted for the match expires before either side can win, then the game is a draw. If the match has only a single innings per side, then a highest number of deliveries for each innings is frequently imposed. Such a match is called a limited overs or one-day match, and the side scoring more runs wins anyway of the number of wickets lost, so that a draw cannot occur. If this kind of match is temporarily intermittent by bad weather, then a complex mathematical formula known as the Duckworth-Lewis method is often used to recalculate a new target score. A one-day match can be declared a No-Result if fewer than a up to that time agreed number of overs have been bowled by either team, in circumstances that make normal recommencement of play impossible.

Tiger

The tiger is a mammal of the Felidae family, one of four large cats in the Panther a genus. Native to the mainland of southeastern Asia, the tiger is an apex predator and the largest feline species in the world, similar in size to the biggest fossil felids. The Bengal Tiger is the most general subspecies of tiger, constituting approximately 80% of the entire tiger population, and is found in India, Bangladesh, Bhutan, Myanmar, and Nepal. An endangered species, the popular of the world's tigers now live in captivity.

The tiger is introverted and territorial, preferring cover in deep forest, but also ranging in open areas. The cat hunts by stalk-and-ambush and may take a variety of mid- and large-sized prey, particularly ungulates. Males are much larger than females and have bigger home ranges. Amongst the nine extant tiger subspecies, there is major size variation.

Bond

In finance, a bond is a debt security, in which the authorized issuer owes the holders a debt and is grateful to repay the principal and interest at a later date, termed maturity. Other conditions may also be attached to the bond issue, such as the obligation for the issuer to provide certain information to the bond holder, or limitations on the behavior of the issuer. Bonds are generally issued for a permanent term longer than ten years. U.S Treasury securities issue debt with life of ten years. New debt between one year and ten years is a note, and new debit less than a year is a bill.

A bond is simply a loan, but in the form of a security, although expressions used is rather different. The issuer is equivalent to the borrower, the bond holder to the lender, and the voucher to the interest. Bonds enable the issuer to finance long-term investments with external funds. Certificates of deposit (CDs) or commercial paper are measured money market instruments.

Social network

A social network is a social structure made of nodes that are tied by one or more specific types of relatives, such as values, visions, idea, financial exchange, friends, kinship, dislike, trade, web links, sexual relations, disease communication or airline routes.Social network analysis views common relationships in terms of nodes and ties. Nodes are the individual actors within the networks, and ties are the associations between the actors. Research in a number of academic fields has shown that social networks operate on many levels, from families up to the level of nations, and play a serious role in determining the way problems are solved, organizations are run, and the degree to which individuals succeed in achieving their goals.

In its simplest form, a social network is a map of all of the appropriate ties between the nodes being studied. The network can also be used to decide the social capital of individual actors. These concepts are often displayed in a shared network diagram, where nodes are the points and ties are the lines.

Electron

In relativistic quantum mechanics, the electron is described by the direct Equation which defines the electron as a point. In quantum field theory, the activities of the electron are described by quantum electrodynamics, a gauge theory. In Dirac's model, an electron is defined to be a mathematical point, a point-like, exciting bare particle surrounded by a sea of interacting pairs of virtual particles and antiparticles. The extraordinarily precise agreement of this forecast with the experimentally resolute value is viewed as one of the great achievements of modern physics.

In the Standard Model of particle physics, the electron is the first-generation stimulating lepton. It forms a weak isospin doublet with the electron neutrino, these two particles cooperate with each other through both the charged and neutral current weak interaction. The electron is very similar to the two more massive particles of higher generations, the muon and the tau lepton, which are identical in charge, spin, and interface but differ in mass.

Languages

Languages that exist only in the spoken form, such as those of many of the Native American Indian tribes, require the use of audio recording campaign such as a digital audio recorder or a tape recorder, augmented by explanatory text written in other languages, for preservation. Recently, efforts have been made to create symbol sets and grammars for such languages to avoid further losses of historically valuable information. Conversely, there are numerous extinct languages which persist only in their printed form. In some cases, experts can only guess at what their spoken form really sounded like. To prevent further losses of this nature, modern linguists have developed supersets of symbols for the purpose of correctly recording the authentic sounds of known languages.

While the superset symbols, which normally encode phonemes and their allophones, could record continuous discussion with nearly flawless accuracy, it would be tedious and unnecessary to record huge volumes of speech in this manner. That said there is a practical application for it, fine tuning of the programming for text-to-speech synthesizers to give computers a voice that sounds extremely human. Where a synthesizer stumbles on a given word, an entry can be added to an omission dictionary, wherein its definition consists of the word respelled in phonemes and allophones.

Voltage

Voltage is the difference of electrical potential between two points of an electrical or electronic circuit, uttered in volts. It measures the potential energy of an electric field to source an electric current in an electrical conductor. Depending on the difference of electrical potential it is called extra low voltage, low voltage, high voltage or extra high voltage.

Between two points in an electric field, such as exists in an electrical circuit, the distinction in their electrical potentials is known as the electrical potential difference. This difference is proportional to the electrostatic force that tends to drive electrons or other charge-carriers from one point to the other. Potential difference, electrical potential, and electromotive force are measured in volts, leading to the commonly used term voltage. Voltage is usually represented in equations by the symbols V, U, or E.

Electrical potential difference can be thought of as the capacity to move electrical charge through a resistance. At a time in physics when the word force was used loosely, the potential difference was named the electromotive force or EMF—a term which is still used in confident contexts.

Hamlet

Prince of Denmark is a calamity by William Shakespeare. It is one of his best-known works, and also one of the most-quoted writings in the English words. Hamlet has been called Shakespeare's greatest playand it is commonly included on lists of the world's greatest books. It is also one of the most popular of Shakespeare's plays, judging by the figure of productions. Hamlet is a tragedy of the retribution genre, in which the title character, and two other characters as well, seek retribution for their fathers' deaths. It incorporate other major human themes, including love, justice, good and evil, and most notably, madness.
Hamlet begins with Francisco on watch task at Elsinore Castle, on a cold, shady night, at midnight. Barnardo approaches Francisco to relieve him on duty, but is not capable to recognize his friend at first in the darkness. The darkness and the mystery, of the set an worrying tone to start the play.

Creditor

A creditor is a party who claims that a second party owes the first party some properties or services. The first party, in common, has provided some property or service to the second party under the assumption that the second party will return an equal property or service. The first party is regularly called a lender, and the second party is frequently called a debtor or borrower.

In other words, your creditors are people to whom you owe money. The term creditor is commonly used in the financial world, particularly in orientation to short term loans, long term bonds, and mortgages. The term creditor derived from the concept of credit. In modern America, credit refers to a rating which indicates the ability of a borrower and likelihood to pay back his or her loan. In earlier times, credit also referred to reputation or trustworthiness.

Earthworm

Earthworm is the ordinary name for the larger members of the Oligochaeta (which is either a class or subclass depending on the author) in the phylum Annelida. In classical systems they were located in the order Opisthopora, on the basis of the male pores opening to the exterior of body posterior to the female pores, even though the male segments are anterior to the female. Cladistic studies have supported placing them instead in the suborder Lumbricina of the arrange Haplotaxida. Folk names for earthworm include "dew-worm", "night crawler" and "angleworm". Earthworms are also called megadriles (or big worms), as divergent to the microdriles, which include the families Tubificidae, Lumbriculidae, and Enchytraeidae, among others. The megadriles are characterized by having a multilayered clitellum (which is much clearer than the single-layered one of the microdriles), a vascular system with true capillaries, and male pores behind the female pores.

There are over 5,500 named classes known worldwide, existing everywhere but Polar and arid climates. They choice in size from two centimeters (less than one inch) to over three meters (almost ten feet) in the Giant Gippsland Earthworm. Amongst the main earthworm species usually found in temperate regions are the reddish colored, deep-burrowing Lumbricus terrestris.

In temperate zone areas, the most usually seen earthworms are lumbricids (Lumbricidae), mostly due to the recent rapid spread of a fairly small number of European species, but there are numerous other families, e.g. Megascolecidae, Octochaetidae, Sparganophilidae, Glossoscolecidae, etc.. These other families are often differing from the lumbricids in behavior, physiology and habitat.

Buzzard

A buzzard is one of some large birds, but there are a number of meanings as detailed below.

In the Old World
Buzzard can mean:

One of several medium-sized, wide-ranging raptors with a robust body and broad wings.
In exacting, those in the genus Buteo. In the Old World, members of this genus are named as "buzzards", but "hawk" is more general in North America.
Specifically, in Europe, the general Buzzard, Buteo, where Buzzard is often used as a synonym.
Any raptor which has the word buzzard as division of its name.

In the New World
Buzzard can mean:

A vulture, mainly the American Black Vulture and Turkey Vulture, or as a general term for vultures and condors.
In parts of the United States where they are considered pest, particularly in rural areas, a derogatory term for certain birds of prey, such as the Chicken hawk (a common colloquial name referring to both the Red-tailed Hawk and the Cooper's Hawk), or the Duck hawk (known elsewhere as the Peregrine Falcon). In the U.S., the term "buzzard" is never used to refer to birds of prey, like hawks, eagles, falcons, and owls, exterior of this context.
Rarely, a derogatory term for any large bird that happens to be a scavenger, such as a raven or albatross (in other words, any large bird that is neither predatory nor flightless).
The Old World and New World uses are approximately antonyms.
