Web development

Web development is a broad term for any activities related to developing a web site for the World Wide Web or an intranet. This can include e-commerce business development, web design, web content development, client-side/server-side coding, and web server configuration. However, among web professionals, "web development" usually refers only to the non-design aspects of building web sites, e.g. writing markup and coding. Web development can range from developing the simplest static single page of plain text to the most complex web-based internet applications, electronic businesses, or social network services.

For larger businesses and organizations, web development teams can consist of hundreds of people. Smaller organizations may only require a single permanent or contracting webmaster, or secondary assignment to related job positions such as a graphic designer and/or Information systems technician. Web development may be a collaborative effort between departments rather than the domain of a designated department.

Calculator

A calculator is a machine for performing calculations. Although modern calculators often incorporate a general purpose computer, the device is calculated for performing specific operations, rather than for flexibility. Modern calculators are more convenient than most computers, though some Pads are comparable in amount to handheld calculators.

In the past, some calculators were as huge as today's computers. The first automatic calculators were mechanical desktop devices which were replaced by electromechanical desktop calculators, and then by electronic devices using first sung valves, then transistors, then hard-wired integrated circuit logic. New calculators are electrically powered and come in innumerable shapes and sizes varying from cheap, give-away, credit-card sized models to more sturdy adding machine-like models with built-in printers.

Animals

Animals are a major group of generally motile, multicultural organisms that feed by consuming material from other living things. Their body plan becomes fixed as they develop, usually early on in their development as embryos, although some undergo a process of metamorphosis later on.

The word "animal" comes from the Latin word animal, of which animal is the plural, and is derived from anima, meaning vital breath or soul. In everyday colloquial usage, the word usually refers to non-human animals. The biological definition of the word refers to all members of the Kingdom Animalia. Therefore, when the word animal is used in a biological context, humans are included.

Inductor

An inductor is a passive electrical device working in electrical circuits for its property of inductance. Inductance is an consequence which results from the magnetic field that forms around a current carrying conductor. Electrical current through the conductor creates a magnetic flux relative to the current. A change in this current creates a change in magnetic flux that, in turn, generates an electromotive force that acts to oppose this change in current. Inductance is a calculate of the generated emf for a unit modify in current. An inductor with an inductance of 1 henry produces an emf of 1 V when the current through the inductor changes at the rate of 1 ampere per second. The number of turns, the area of each loop/turn, and what it is wrapped around influence the inductance.

An inductor opposes changes in the current. An ideal inductor would offer no resistance to a constant direct current, however, only superconducting inductors have truly zero electrical resistance. Inductors are used expansively in analog circuits and signal processing.

Essentials of Healthy life

Health is wealth so preserve it. Life is short so use it in the right way. Cleanliness merely fits with the apt meaning of being free from dirt, dust, germs and bad smells. A recent shift has now taken place to recognise that ‘germs’ may play a major role in our immune systems. So experts say washing hands frequently, specially when in an environment of many people with infections and diseases. Washing is one of the best way to achieve cleanliness.Have a brief overlook on the following issue to be aware of how to keep one self clean.

A step way process regarding cleanliness of hands is given below:
• Use warm water
• But avoid scorching your hands.
• Use anti-bacterial soap or hand wash.
• Wash between fingers and use paper towels to wipe off.
Washing of hands has to be followed:
• Before eating
• After eating
• After using the toilet
• After playing outdoor games
• After attending to a sick person
• After blowing nose, coughing, or sneezing; and after handling pets.
The proverb "Cleanliness is next to Godliness," a common phrase that describes humanity's high opinion of being clean. Purposes of cleanliness include health, beauty and to avoid the spreading of germs .If your hands have any kind of skin cut or infection, wash hands with an anti bacterial soap. Thoroughly wash with hot, soapy water all surfaces that come in contact with raw meat, poultry, fish, and eggs before moving on to the next step in food preparation. Consider using paper towels to clean kitchen surfaces.

Rain sensors

Rain sensors for irrigation systems are obtainable in both wireless and hard-wired versions, most employing hygroscopic disks that bulge in the presence of rain and shrink back down again as they dry out - an electrical switch is in turn depressed or released by the hygroscopic disk stack. However, some electrical type sensors are also marketed that use tipping bucket or conductance type probes to measure rainfall.

Wireless and wired versions both use alike mechanisms to momentarily suspend watering by the irrigation controller - purposely they are connected to the irrigation controller's sensor terminals, or are installed in series with the solenoid valve common circuit such that they stop the opening of any valves when rain has been sensed. Some irrigation rain sensors also contain a freeze sensor to keep the system from operating in freezing temperatures Some US states, such as Florida, New Jersey, Minnesota, and Connecticut mandate the use of a rain sensor in all new lawn sprinkler systems.

Festival

A festival is an event, usually dramatic by a local community, which centers on some unique aspect of that community. Among many religions, a feast or festival is a set of merriment in honor of God or gods. A feast and a festival are traditionally interchangeable. However, the term feast has also entered general secular parlance as a synonym for any large or elaborate meal. When used as in the meaning of a festival, most repeatedly refers to a religious festival rather than a film or art festival.
Festivals are many types, serve to meet specific social needs and duties, as well as to present entertainment. These times of celebration offer a intellect of belonging for religious, social, or geographical groups. Modern festivals that focus on educational or ethnic topics seek to inform members of their traditions. In past times, festivals were times when the elderly shared stories and transferred convinced knowledge to the next generation. Historic feast often provided a means for unity among families and for people to come across mates. Select anniversaries have annual festivals to celebrate previous significant occurrences.

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.

Security

Security is the condition of being sheltered against danger or loss. In the general sense, security is a perception similar to safety. The nuance between the two is an added emphasis on being protected from dangers that initiate from outside. Individuals or actions that encroach upon the condition of protection are responsible for the breach of security.
The word security in general procedure is synonymous with safety, but as a technical term security means that something not only is protected but that it has been secured. A condition that results from the establishment and maintenance of protective measures that ensures a state of inviolability from hostile acts or influences. With respect to classified matter, the condition that prevents unauthorized persons from having right to use to official information that is safeguarded in the benefit of national security.

Light

Light is electromagnetic energy with a wavelength that is observable to the eye or, in a technical or scientific context, the word is sometimes used to mean electromagnetic emission of all wavelengths. The elementary element that defines light is the photon. The three basic properties of lights are Intensity, or alternatively amplitude, which is related to the observation of brightness of the light, Frequency, or alternatively wavelength, perceived by humans as the color of the light, and Polarization, which is only weakly perceptible by humans under ordinary circumstances. Due to its wave–particle duality, light can show properties of both waves and particles. The study of light, known as optics, is an important research area in modern physics.
The first successful quantity of the speed of light in Europe using an earthbound apparatus was carried out by Hippolyte Fizeau in 1849. Fizeau aimed at a beam of light at a mirror several thousand metres away, and placed a rotating cog wheel in the path of the beam from the source to the mirror and back again. At a certain rate of rotary motion, the beam could pass through one gap in the wheel on the way out and the next gap on the way back. Knowing the distance to the mirror, the number of teeth on the wheel, and the rate of rotation, Fizeau calculated the speed of light as 313 000 km/sv

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.

Safety

Safety is the state of being safe, the situation of being protected against physical, social, spiritual, financial, political, emotional, occupational, psychological, educational or additional types or consequences of failure, damage, error, accidents, harm or any other event which could be considered non-desirable. This can take the form of being protected from the event or from exposure to something that causes health or reasonable losses. There also are two slightly different meanings of safety, a safety home may indicate its protection ability against external harm events, and the second that its internal installations are safe for its habitants.

Safety can be limited in relative to some guarantee or a standard of insurance to the quality and unharmful function of an object or organization. It is used in order to ensure that the object or association will do only what it is meant to do. Normative safety is a term used to explain products or designs that meet applicable design standards. Substantive safety stands for that the real-world safety history is favorable, whether or not standards are met. Perceived safety refers to the stage of comfort of users

Hockey

Hockey is any of a family of sports in which two teams struggle by trying to maneuver a ball, or a hard, surrounding disc called a puck, into the opponent's net or goal, using a hockey stick. Field hockey is played on nettle, natural grass, sand-based or water-based artificial turfs, with a small, hard ball. The game is popular among both males and females in many countries of the world, mostly in Europe, India, Pakistan, Australia, New Zealand, South Africa and South Asia. In most countries, the game is played between single-sex sides, even though it can be played by mixed-sex sides. In the United States and Canada it is played mostly by women.Ball hockey is played in a gym using sticks and a ball, often a tennis ball with the hair removed.

There are early representations and reports of hockey-type games being played on ice in the Netherlands, and reports from Canada from the beginning of the nineteenth century, but the modern game was initially planned by students at McGill University, Montreal in 1875 who, by two years later, codified the first set of ice hockey rules and organized the first teams.

Table

In relational databases, SQL databases, and flat file databases, a table is a set of data elements that is controlled using a model of horizontal rows and vertical columns. The columns are identified by name, and the rows are identified by the values appearing in a particular column division which has been identified as a candidate key. Table is another term for family although there is the difference in that a table is usually a multi-set of rows whereas a relation is a set and does not allow duplicates. A table has a particular number of columns but can have any number of rows. Besides the actual data rows, tables generally have related with them some meta-information, such as constraints on the table or on the values within particular columns.

The data in a table does not have to be actually stored in the database. Views are also relational tables, but their data is considered at query time. In non-relational systems, such as hierarchical databases, the isolated counterpart of a table is a structured file, representing the rows of a table in each record of the file and each column in a record.

Inductor

An inductor is a passive electrical device working in electrical circuits for its property of inductance. Inductance is an consequence which results from the magnetic field that forms around a current carrying conductor.

An inductor opposes changes in the current. An ideal inductor would offer no resistance to a constant direct current, however, only superconducting inductors have truly zero electrical resistance. Inductors are used expansively in analog circuits and signal processing.

IPL

IPL is Initial program load, used in operating system. In computing, booting is a bootstrapping method that starts operating systems when the user turns on a computer system. A boot series is the set of operations the computer performs when it is switched on that loads an operating system.

Most computer systems can only complete code found in the memory (ROM or RAM). Modern operating systems are stored on hard disks, or occasionally on Live CDs, USB flash drives, or other non-volatile storage devices. When a computer is first power-driven on, it doesn't have an operating system in memory. The computer's hardware alone cannot perform complex measures such as loading a program from disk, so an apparent paradox exists, to load the operating system into memory, one appears to need to have an operating system already loaded. The System/360 IPL function reads 24 bytes from an operator-specified or pre-configured machine into memory starting at location zero. The second and third groups of eight bytes are treated as Channel Command Words (CCWs) to maintain loading the startup program. When the I/O channel instructions are complete, the first group of eight bytes is then loaded into the Program Status Word (PSW) register and the startup program begins completing at the designated location.

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.

Computation

Computation is a common term for any type of information processing that can be represent mathematically. This includes phenomenon ranging from simple calculations to human idea. In a more narrow meaning, computation is a process following a well distinct model that is understood and can be expressed in an algorithm, protocol, network topology, etc.

These hypothetical computing equipment can be viewed as idealised analog computers which operate on real numbers and are differential, whereas digital computers are partial to computable numbers and are algebraic. Depending on the model select, this may enable real computers to solve problems that are inextricable on digital computers.

Child Care

Childcare is the act of caring for and supervising minor children.In Australia, daycare is referred to as childcare It is traditional in western society for children to be looked after by one or both of their parents, but the need for two-job households means that childcare is often delegated, at least part of the time, to childminders or crèches.Most Western countries also have compulsory education, and during the time the children are at school, the school will act in loco parentis.Where parents are missing or dead, or unable or unfit to care for children, state agencies such as social services may take on the childcare role.Wealthy people who prefer the services of professionals may delegate the parental role almost completely to nannies.

However, for many the use of paid childcare is a matter of choice with arguments raging on both sides about whether children suffer or not. There is no doubt that for all children the first few years are vitally important to form a basis for good education, morality, self-discipline and social integration. Consistency of approach, skills and qualifications of careers and community ownership have been shown in many studies to improve the chances of a child reaching his or her full potential for example a recent study in Australia showed that 20% of careers working in large commercial child care chains would not put their own children in the centre they work in, whereas only 2% of careers in community owned not-for-profit centres had similar concerns.

Ethics

Ethics (from the Ancient Greek ἠθικός ēthikos, the adjective of ἤθος ēthos "custom, habit"), a major branch of philosophy, is the study of values and customs of a person or group. It covers the analysis and employment of concepts such as right and wrong, good and evil, and responsibility. It is divided into three primary areas: meta-ethics (the study of the concept of ethics), normative ethics (the study of how to determine ethical values), and applied ethics (the study of the use of ethical values There are two main strands of thought, "non-realism" and "realism," that attempt to explain what ethical values and claims are actually about.
One strand is commonly termed 'non-realism', because it suggests moral values are creations, dependent on people's feelings and goals regarding themselves and others (emotivism or prescriptivism) or on their belief systems (cultural or individual relativism). Despite the name 'non-realist', such theories may see reality as important in shaping the human choice of ethical values. This could occur indirectly by, for example, the evolutionary or developmental shaping of human psychology, or directly through, for example, people assessing and debating the likely consequences of their actions.
Another group of meta-ethical theories, which is called 'realism', by contrast, holds that moral value is somehow an intrinsic property of the world and that ethical principles are simply discovered or intuited. Under this view, ethical values held by people can at best reflect an independent Truth by which their validity must be judged. These theories may be derived from theology or naturalism.
Although not explicitly reflected in the discussion that follows, any informed ethics discussion will consider the meta-ethical position of the participants in the discussion. The importance of this distinction can be seen clearly when we consider ethics in psychology (below), in which Lawrence Kohlberg's clearly realist theory might be contrasted against Phil Roberts, Jr.'s arguably non-realist theory. Any ethics discussion that does not first consider the non-realist or realist standings of its participants is doomed to frustration.

Economy

Economy refers to the human activities related with the production, distribution, exchange, and consumption of goods and services. However, its definition transformed throughout history with the activities attributed to economy. The composition of a given economy is inseparable from civilization's history and social organization, and from Earth's geography and ecology, e.g. ecoregions which represent different agricultural and resource extraction opportunities, among other factors.
The fields of study exploring, registering and describing the economy or a part of it, belong in general to the social sciences and include economics as well as branches of history (economic history) or geography (economic geography). Subgroups of economics are macroeconomics, microeconomics, econometrics, national economy, political economy, classical economy, economic anthropology, economic democracy and more. Economic measures such as the Gross Domestic Product (GDP) are part of econometrics. Practical fields more directly related to the human activities involving production, distribution, exchange, and consumption of goods and services as a whole, range from engineering to management and business administration to applied science to finance. Consumption, saving and investment, are core variable components in the economy and determine equilibrium in the markets. There are three main sectors of economic activity: primary, secondary and tertiary.

Fashion and the media

An important part of fashion is fashion journalism. At the beginning of the twentieth century, fashion magazines began to include photographs and became even more powerful than in the past. In cities throughout the world these magazines were greatly sought-after and had a profound effect on public taste. Talented illustrators drew exquisite fashion plates for the publications which covered the latest developments in fashion and beauty. Perhaps the most famous of these magazines was La Gazette du bon ton which was founded in 1912 by Lucien Vogel and regularly published until 1925.

Debenture

In finance, a debenture is a long-term debt instrument used by governments and large companies to obtain funds. It is similar to a bond except the securitization conditions are different. A debenture is usually unsecured in the sense that there are no liens or pledges on specific assets. It is however, secured by all properties not or else pledged. In the case of bankruptcy debenture holders are considered general creditors.

The benefit of debentures to the issuer is they leave specific assets tangential, and thereby leave them open for subsequent financing.

Geography of Bhutan

The northern region consists of an arc of glaciated mountain peaks with a very high cold climate at the highest elevations. Most peaks in the north are over 23,000 feet above sea level; the highest point is claimed to be the Kula Kangri, at 24,780 feet, but detailed topographic studies claim Kula Kangri is wholly in Tibet and modern Chinese measurements claim that Gangkhar Puensum, which has the peculiarity of being the highest unclimbed mountain in the world, is higher at 24,835 feet. Watered by snow-fed rivers, alpine valleys in this region provide pasture for livestock, tended by a sparse population of migratory shepherds. The Black Mountains in central Bhutan form a watershed between two major river systems i.e. Mo Chhu and Drangme Chhu. Peaks in the Black Mountains range between 4,900 feet and 8,900 feet above sea level, and fast-flowing rivers have carved out deep gorges in the lower mountain areas. Woodlands of the central region offer most of Bhutan's forest production. The Torsa, Raidak, Sankosh, and Manas are the main rivers of Bhutan, flowing through this region. Most of the people live in the central highlands.
