Policies for Schools

The recommendations

*
Schools should have Acceptable Internet Use Policies, for pupils and for staff.
*
Policies should take into account supervised and unsupervised use, both during school time and also out with school hours.
*
These policy documents should include a clear section about the school's responsibilities regarding publishing pupils' information on a school website.
*
Policies should include reference to Child Protection procedures.
*
Guidelines for Internet use should be displayed in obvious places, perhaps on the sides of the computers themselves.
*
Any guidelines that are developed within the school should be shared with others to increase networking and make efficient use of resources.

Body painting

Body painting, or sometimes body painting, is a form of body art, considered by some as the earliest form of art. Unlike tattoo and other forms of body art, body painting is temporary, painted onto the human skin, and lasts for only several hours, or at most in the case of Mehndi or "henna tattoo" a couple of weeks. Body painting that is partial to the face is known as face painting.

Chevrolet

Chevrolet (IPA: /ˌʃɛvroʊˈleɪ/ - French origin) (colloquially Chevy) is a brand of automobile, shaped by General Motors (GM). It is the top selling GM marque and the best known brand of GM worldwide [citation needed], with Chevrolet or Chevy being at times synonymous with GM.

Chevrolet offers over 20 vehicles and a lot of various enhanced versions in its home market. The brand's vehicles range from subcompact cars to medium duty commercial trucks. Its number one sellers in the United States take in the Silverado pickup, which is currently the 2nd best-selling vehicle in the United States behind the Ford F-Series and the Impala, which is the number one selling car with a domestic nameplate in the United States.

Great Pyramid of Giza

The Great Pyramid of Giza, also called Khufu's Pyramid or the Pyramid of Khufu, and Pyramid of Cheops, is the oldest and most significant of the three pyramids in the Giza Necropolis bordering what is now Cairo, Egypt in Africa, and is the only remaining member of the Seven Wonders of the Ancient World. It is held the pyramid was built as a tomb for Fourth dynasty Egyptian pharaoh Khufu (Cheops in Greek) and builds over a 20 year period ultimate around 2560 BC. The Great Pyramid was the tallest man-made structure in the world for over 3,800 years. Obviously all that remains is the underlying step-pyramid core structure seen today. Many of the casing stones that once enclosed the structure can still be seen around the base of the Great Pyramid. There have been varying scientific and alternative theories regarding the Great Pyramid's construction techniques. Most accepted construction theories are based on the idea that it was built by moving huge stones from a quarry and dragging and lifting them into place.

There are three recognized chambers inside the Great Pyramid. The lowest chamber is cut into the bedrock upon which the pyramid was built and was incomplete. A passage from the Grand Gallery leads to the Queen's Chamber, while an entrance leads from the Grand Gallery to the King's Chamber. The sarcophagus of the King's Chamber was hollow out of a single piece of Red Aswan granite and has been found to be too large to fit through the passageway leading to the chamber. Both the King's Chamber and the Queen's Chamber contain small shafts that climb out of the pyramid. Egyptologists now conclude they were instead used for ceremonial purposes. The Great Pyramid is the only pyramid known to contain both ascending and descending passages. The Great Pyramid of Giza is the main part of a complex setting of buildings that included two mortuary temples in honor of Khufu (one close to the pyramid and one near the Nile), three smaller pyramids for Khufu's wives, an even smaller "satellite" pyramid, a raised causeway linking the two temples, and small mastaba tombs surrounding the pyramid for nobles.

Mountain

A mountain is a landform that extends over the nearby terrain in a limited area. A mountain is normally steeper than a hill, but there is no commonly accepted standard definition for the height of a mountain or a hill though a mountain typically has an exacting summit.

Mountains are on the whole given as heights over mean sea level. The Himalayas generally 5 km above sea level, at the same time as the Andes average 4 km. Most other mountain has 2 – 2.5 km. The peak mountain on Earth is Everest, 8,848 m (29,028 feet), locate in the world's most vital mountain range, the Himalayas.

Sufficiently big mountains have particularly different climatic conditions at the top than at the base, and will thus have different life zones at different altitudes on their slopes. The plants and animals of a sector are to some extent lonely when the zones above and below are harsh, and numerous unique species take place on mountainsides as an end result. Great cases are identified as sky islands. Cloud forests are forests on mountain sides which are a focus for moisture from the air, and thus creating a single ecosystem. Very tall mountains may possibly be enclosed in ice or snow.

Management of working capital

Management will use a federation of policies and techniques for the management of working capital. These policies aim at managing the current assets usually cash and cash equivalents, inventories and debtors and the short term financing, such that cash flows and returns are acceptable.
Inventory management: Identify the level of inventory which allows for continuous production but reduces the investment in raw materials - and minimizes reordering costs - and hence increases cash flow; see Supply chain management; Just in Time (JIT); Economic order quantity (EOQ); Economic production quantity (EPQ).
Debtors management: Identify the appropriate credit policy, i.e. credit terms which will pull towards you customers, such that any impact on cash flows and the cash change cycle will be offset by increased revenue and hence Return on Capital (or vice versa); see Discounts and allowances.
Short term financing: Identify the appropriate source of financing, given the cash conversion cycle: the inventory is preferably financed by credit granted by the supplier; however, it may be necessary to make use of a bank loan (or overdraft), or to "convert debtors to cash" through "factoring".
Cash management: Identify the cash balance which allows for the business to meet day to day expenses, but reduces cash holding costs.

Swaption

A swaption is an option granting its owner the right but not the obligation to enter into a fundamental swap. Although options can be traded on a diversity of swaps, the term "swaption" typically refers to options on interest rate swaps.

There are two types of swaption contracts:

A payer swaption gives the owner of the swaption the right to come into a swap where they pay the fixed leg and obtain the floating leg.
A receiver swaption gives the owner of the swaption the right to enter into a swap where they will receive the fixed leg, and pay the floating leg.
The buyer and seller of the swaption agree on:

The premium (price) of the swaption
the strike rate (equal to the fixed rate of the underlying swap)
Length of the option period (which frequently ends two business days prior to the start date of the underlying swap),
the term of the underlying swap,
Notional amount,
Amortization, if any
Frequency of settlement payments on the underlying swap.

Animals

Animals are a major set of organisms, classified as the empire Metazoa. In common they are multicultural, receptive to their surroundings, and afford for by overriding other organisms or parts of them. Their body plan becomes fixed when they enlarge, commonly early on in their growth as embryos, in spite of the fact that some feel a process of metamorphosis later on.

The word "animal" draws closer from the Latin word animal, of which Metazoa is the plural, and is resulting from anima, sense very significant breath or soul. In every day colloquial usage, the word often refers to non-human animals. The biological meaning of the word refers to every members of the empire Animalia. As a result, as the word "animal" is used in a biological condition, humans are included.

Global financial system

The global financial system (GFS) is a financial system consisting of institutions and rules that act on the international level, as distinct to those that act on a national or regional level. The main players are the global institutions, such as International Monetary Fund and Bank for International Settlements, national agencies and government departments, e.g., central banks and finance ministries, and private institutions acting on the global scale, e.g., banks and hedge funds.

Lagrange's theorem group theory and History

Lagrange's theorem, in the mathematics of grouping theory, states that for any finite group G, the arrange (number of elements) of all subgroup H of G divides the order of G. Lagrange's theorem is named after Joseph Lagrange.

Lagrange did not prove Lagrange's theorem in its general form. What he in fact proved was that if a polynomial in n variables has its variables permuted in all n! Ways, the number of various polynomials that are obtained is constantly a factor of n! The number of that kind of polynomials is the index in the symmetric group Sn of the subgroup H of permutations which preserve the polynomial. So the size of H divides n! With the later improvement of abstract groups, this end result of Lagrange on polynomials was known to extend to the general theorem about finite groups which currently bears his name.

Computer printer

A computer printer, or more normally a printer, produces a hard copy (permanent human-readable text and/or graphics) of documents stored in electronic form, frequently on physical print media such as paper or transparencies. Many printers are mostly used as local computer peripherals, and are attached by a printer cable to a computer which serves as a document source. Some printers, commonly known as network printers, have built-in network interface (typically wireless or Ethernet), and can serve as a hardcopy device for any user on the network. Individual printers are frequently intended to support both local and network connected users at the same time.

In addition, many modern printers can directly interface to electronic media such as memory sticks or memory cards, or to image capture devices such as digital cameras, scanners; a number of printers are combined with a scanners and/or fax machines in a single unit. Printers that contain non-printing features are sometimes called Multifunction Printers (MFP) or Multi-Function Devices (MFD).

Pulses

Pulses are defined by the Food and Agricultural Organization of the United Nations (FAO) as yearly leguminous crops yielding from one to twelve grains or seeds of variable size, shape and color surrounded by a pod. Pulses being used for food and animal feed.

The term pulses, as used by the FAO, are kept for crops harvested solely for the dry grain. This therefore excludes green beans and green peas, which are measured vegetable crops. Also barred crops which are mainly grown for oil extraction oilseeds like soybeans and peanuts, and crops which are used exclusively for sowing (clovers, alfalfa).

Pulses are main food crops due to their high protein and necessary amino acid content. Like many leguminous crops, pulses play a key role in crop turning round due to their capability to fix nitrogen.

Salwar kameez

Salwar kameez is also spelled shalwar kameez and shalwar qamiz is a customary dress worn by both women and men in Pakistan, India, Bangladesh, and Afghanistan. It is now and then known as Punjabi suit owing to its popularity in the Punjab region and the Pathani suit, due to the fact that the Pathans of Kabul set up the dress to the rest of South Asia.

It is loose pajama like trousers the legs are wide at the top and thin at the bottom,
The kameez is a long shirt or tunic. The part seams known as the chaak are left open under the waist-line, which gives the wearer greater freedom of movement. In Afghanistan and Pakistan, it is the special garment of both sexes. In Bangladesh and India, it is usually a woman's garment though the majority of Indian women wear traditional clothing, the men in India can be found in more comfortable in western clothing. Shalwar kameez is the traditional dress worn by a many peoples of south-central Asia. In India and Pakistan it is a largely popular style of dress, Shalwar or Salwar is a short loose or parallel trouser.

Fixed income

Fixed income refers to any kind of investment that yields a normal or fixed return.
For example, if you create use of money and have to pay interest once a month, you have issue a fixed-income security. When a company does this, it is frequently called a bond or corporate bank debt even though 'preferred stock' is also sometimes measured to be fixed income. Sometimes people misspeak when they talk about fixed income; bonds really have higher risk, while notes and bills have less risk because these are issued by Government agencies.

The term fixed income is also useful to a person's income that does not differ with each period. This can include income derivative from fixed-income investments such as bonds and preferred stocks or pensions that guarantee a fixed income.

Planet

A planet, as defined by the International Astronomical Union (IAU), is a celestial body orbiting a star or stellar remnant that is enormous enough to be rounded by its own gravity, not massive enough to cause thermonuclear fusion, and has cleared its neighboring region of planetesimals.

The term planet is an antique one having ties to history, science, myth, and religion. The planets were originally seen as a divine attendance; as emissaries of the gods. Even today, many people continue to believe the movement of the planets affects their lives, although such causation is rejected by the scientific community. As scientific knowledge advanced, the human awareness of the planets changed over time, incorporating a number of disparate objects. Even now there is no recognized definition of what a planet is. In 2006, the IAU formally adopted a resolution defining planets within the Solar System. This definition has been both praised and criticize, and remains disputed by some scientists.

Under IAU definitions, there are eight planets in the Solar System (Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune) and 270 further solar ones. The Solar System also contains at slightest three dwarf planets (Ceres, Pluto, and Eris). Many of these planets are orbited by one or more moons, which can be superior than small planets. Planets are usually divided into two main types: large, low-density gas giants and smaller, rocky terrestrials.

Solar tracker

A solar tracker is a device for orienting a solar photovoltaic panel or concentrating solar reflector or lens toward the sun. Concentrators, especially in solar cell applications, require a high degree of accuracy to ensure that the concentrated sunlight is directed precisely to the powered device, which is at (or near) the focal point of the reflector or lens. Non-concentrating applications require less accuracy, and a tracker is not necessary, but can substantially improve the amount of power produced by a system by enhancing morning and afternoon performance.

Plesiosaur

Plesiosaurs(Greek: plesios meaning 'near' or 'close to' and sauros meaning 'lizard') were carnivorous aquatic (mostly marine) reptiles. After their discovery, they were somewhat fancifully said to have resembled "a snake threaded through the shell of a turtle", although they had no shell. The common name 'plesiosaur' is applied both to the 'true' plesiosaurs (Suborder Plesiosauroidea) and to the larger taxonomic rank of Plesiosauria, which includes both long-necked (elasmosaurs) and short-necked (polycotylid) forms. Short-necked, large-headed plesiosaurs are more properly called pliosaurs. There were many species of plesiosaurs and not all of them were as large as Liopleurodon, Kronosaurus or Elasmosaurus.

Proportional control

When controlling the temperature of an industrial furnace, it is usually better to control the opening of the fuel valve in proportion to the current needs of the furnace. This helps avoid thermal shocks and applies heat more effectively.

Proportional negative-feedback systems are based on the difference between the required set point (SP) and measured value (MV) of the controlled variable. This difference is called the error. Power is applied in direct proportion to the current measured error, in the correct sense so as to tend to reduce the error (and so avoid positive feedback). The amount of corrective action that is applied for a given error is set by the gain or sensitivity of the control system.

Living systems theory

Living systems theory is an offshoot of Bertalanffy's general systems theory, created by James Grier Miller, which was intended to formalize the concept of "life". According to Miller's original conception as spelled out in his magnum opus Living Systems, a "living system" must contain each of 20 "critical subsystems", which are defined by their functions and visible in numerous systems, from simple cells to organisms, countries, and societies. In Living Systems Miller provides a detailed look at a number of systems in order of increasing size, and identifies his subsystems in each.

James Grier Miller (1978) wrote a 1,102-page volume to present his living systems theory. He constructed a general theory of living systems by focusing on concrete systems—nonrandom accumulations of matter-energy in physical space-time organized into interacting, interrelated subsystems or components. Slightly revising the original model a dozen years later, he distinguished eight “nested” hierarchical levels in such complex structures. Each level is “nested” in the sense that each higher level contains the next lower level in a nested fashion.

Classical Marxism

Classical Marxism refers to the body of theory directly expounded by Karl Marx and Friedrich Engels. The term "Classical Marxism" is often used to distinguish between "Marxism" as it is broadly understood and "what Marx believed", which is not necessarily the same thing. For example, shortly before he died in 1883, Marx wrote a letter to the French workers' leader Jules Guesde and to his own son-in-law Paul Lafargue, both of whom claimed to represent Marxist principles, in which he accused them of "revolutionary phrase-mongering" and of denying the value of reformist struggles. Paraphrasing Marx: "If that is Marxism, then I am not a Marxist". As the American Marx scholar Hal Draper remarked, "there are few thinkers in modern history whose thought has been so badly misrepresented, by Marxists and anti-Marxists alike."
