Snake River

The Snake River is the river, in the western part of the United States. The Snake River is 1,038 miles (1,670 km) in total length, and is the Columbia River's most important tributary. The Lewis and Clark expedition (1803-6) was the first main U.S. exploration of the river, and the Snake was one time known as the Lewis River. The Snake River's many hydroelectric power plants are a most important starting place of electricity in the region. Its watershed offers irrigation for various projects, as well as the Minidoka, Boise, Palisades, and the Owyhee projects by the U.S. Bureau of Reclamation, with a variety of private projects for example, at Twin Falls. On the other hand, these dams have as well had an adverse environmental effect on wildlife, most remarkably on wild salmon migrations.

A planet, is a extraterrestrial body orbiting a star or stellar remnant that is massive adequate to be rounded by its own gravity, not massive enough to cause thermonuclear fusion in its core, and has cleared its neighbouring region of planetesimals

After stars and stellar remnants, planets are a few of the most massive objects known to man. They play an important part in the structure of planetary systems, and are also considered, along with large moons, the most feasible environment for life. Thus planetary science is crucial not only to comprehend the structure of the universe, but also to better understand the development of life, and to aid the search for extraterrestrial intelligence. Additionally, the planets visible from Earth have played a vital role in the shaping of human culture, religion and philosophy in abundant civilisations. Even today, many people continue to believe true the movement of the planets affects their lives, all though such a causation is discarded by the scientific community.

A forest is an area with a high bulk of trees. There are several definitions of a forest, based on a variety of criteria. These plant communities face large areas of the globe and function as animal habitats, and soil conservers, constituting one of the most important aspects of the Earth's biosphere. While frequently thought of as carbon dioxide sinks, grown-up forests are approximately carbon neutral with only troubled and young forests acting as carbon sinks. However mature forests do play a main role in the global carbon cycle as stable carbon pools, and authorization of forests leads to an increase of impressive carbon dioxide levels.

Forests sometimes have many tree species within a small area or comparatively few species over large areas. Forests are frequently home to many animal and plant species, and biomass per unit area is high compared to other plants communities. Much of this biomass occurs below-ground in the origin systems and as partly decomposed plant accumulation. The woody element of a forest contains lignin, which is comparatively slow to decompose compared with other organic materials such as cellulose or carbohydrate.

Music is an art structure that involves organized sounds and silence. It is expressed in terms of and the value of sound

Music may also involve generative forms in time through the creation of patterns and combinations of normal stimulus sound. Music may be used for artistic, expansive, entertainment, traditional purposes.

In the Romantic period, music became more expressive and touching, increasing to encompass literature, and philosophy. Later Romantic composers created multifaceted and frequently much longer musical works. The 20th Century saw a revolution in music listening as the broadcasting gained popularity worldwide and new media and technologies were developed to record, capture, reproduce and distribute music. 20th Century music brought a new liberty and wide testing with new musical styles and forms that challenged the accepted rules of music of earlier periods.

Nature, in the broadest logic, is corresponding to the natural world, physical world or material world. "Nature" refers to the phenomena of the physical world, and also to living in general. The term usually does not contain manufactured things and human interaction unless capable in ways such as, e.g., "human nature" or "the whole of nature". Nature is also normally distinguished from the mystical. It ranges in level from the subatomic to the galactic.

Within the different uses of the word today, "nature" may refer to the universal realm of different types of living plants and animals, and in several cases to the processes associated with non-living objects – the way that particular types of things exist and change of their own pact, such as the weather and geology of the Earth, and the subject and power of which all these things are composed. It is often taken to mean the "natural surroundings" or rocks, forest and in general those things that have not been significantly altered by human involvement, or which persist in spite of human intervention. This more usual concept of natural things which can still be found today implies a difference between the natural and the artificial, with the latter being understood as that which has been brought into being by a human awareness or mind.

Wallpaper is material which is used to coat and decorate the interior walls of home, offices, and other buildings; it is one part of interior decoration. Wallpapers are usually sold in rolls and are place onto a wall using wallpaper glue.

Wallpapers can appear either plain so it can be decorated or with patterned graphics. Wallpaper printing techniques contain surface printing, gravure printing, silk screen-printing, and rotary printing. Mathematically speaking, there are seventeen basic patterns, described as wallpaper groups, which can be used to tile an countless plane. All artificial wallpaper patterns are based on these groups. A single model can be issued in several different color ways.

Culture usually refers to patterns of human being activity and the representative structures that give such activity meaning. Different definitions of "culture" reflect special theoretical bases for considerate for evaluating, human activity. Most general, the term culture denotes entire product of an individual, group or society of smart beings. It includes technology, art, science, with moral systems and the feature behaviors and practice of the selected intelligent entities. In particular, it has exact more detailed meanings in different domains of human activities.

Many people nowadays have a thought of "culture" that developed in Europe through the 18th and early 19th centuries. This view of culture reflected inequalities within European societies, and between European powers and their colonies around the world. It identifies "culture" with "society" and contrasts it with "nature." According to this method of view, one can organize some countries as more civilized than others, and some people as more cultured than others.

CD-ROM (an abbreviation of "Compact Disc read-only memory") is a Compact Disc that contains information accessible by a computer. While the Compact Disc format was formerly designed for music storage and playback, the format was later adapted to hold any form of binary data. CD-ROMs are commonly used to distribute computer software, including games and multimedia applications, though any data can be stored (up to the capacity limit of a disc). Some CDs seize both computer data and audio with the latter capable of being played on a CD player, whilst data (such as software or digital video) is only usable on a computer. These are called Enhanced CDs.

Although many people use lowercase letters in this acronym, proper appearance is in all capital letters with a hyphen between CD and ROM. It was also suggested by some, specially soon after the technology was first released, that CD-ROM was an acronym for "Compact Disc read-only-media", or that it was a more 'correct' definition. This was not the purpose of the original team who developed the CD-ROM, and common acceptance of the 'memory' definition is now almost universal. This is probably in no small part due to the prevalent use of other 'ROM' acronyms such as Flash-ROMs and EEPROMs where 'memory' is the correct term.

The core of the Sun is considered to extend from the center to about 0.2 solar radii. It has a mass of up to 150,000 kg/m3 (150 times the density of water on Earth) and a temperature of close to 13,600,000 kelvins (by contrast, the surface of the Sun is close to 5,785 kelvins (1/2350th of the core)). Through most of the Sun's life, energy is formed by nuclear fusion through a series of steps called the p-p (proton-proton) chain; this process converts hydrogen into helium. The core is the only spot in the Sun that produces an substantial amount of heat via fusion: the rest of the star is heated by energy that is transferred outward from the core. All of the energy formed by fusion in the core must travel through many consecutive layers to the solar photosphere before it escapes into space as sunlight or kinetic energy of particles.

Tourism is traveling for the most part fun or vacation purposes. According to the World Tourism association, tourists are public who "travel to and stay in places outside their usual location for not more than one repeated year for vacation, business and other purposes not related to the use of an activity compensated from within the place visited". Tourism has happen to a very popular, overall activity. In 2004, there were over 763 million international tourist arrivals. Major physical elements include transportation, lodging, and other components of a hospitality industry.

Tourism is very important for many countries, due to the earnings generated by the spending of supplies and services by tourists, the assessment levied on businesses in the tourism industry, and the opportunity for employment and financial development by working in the industry. For these reasons, NGOs and government agencies may sometimes sponsor a specific area as a tourist intention, and support the development of a tourism industry in that area.

Sport is an activity to facilitate is governed by a set of rules or customs and frequently engaged in competitively. Used by itself, sports generally refer to activities where the physical capabilities of the participant are the sole or primary determiner of the outcome, but the term is also used to comprise activities such as mind sports and motor sports where psychological acuity or equipment quality are major factors. Sports are used as hobby for the player and the viewer. It has also proved by experiments that daily exercise would boost mental strength and power to study.

Sports have been ever more organized and keeping pace from the time of the Ancient Olympics up to the present century. Industrialization has brought improved leisure time to the citizens of developed and developing countries, leading to more time for people to be present at and follow spectator sports, greater contribution in athletic activities, and increased accessibility. These trends continued with the beginning of mass media and global statement.

A river is a natural waterway, which moves water diagonally the land from upper to lower elevations, and is a main part of the water cycle. The water within a river is generally from rain through surface runoff and release of stored water in natural reservoirs, such as groundwater.

The beginning of a mountain river from their resource, all rivers run downhill, naturally terminating in the sea or in a lake, during a flowing together. In dry areas rivers sometimes finish by losing water to evaporation. River water may also gain access to the soil or pervious rock, where it becomes groundwater. Extreme abstraction of water for use in industry, irrigation, etc., can also source a river to dry before reaching its natural boundary.

Solar System

Solar System consists of the Sun and the other space objects gravitationally bound to it: the eight planets, their 162 known moonsthree currently recognized dwarf planets (including Pluto) and their four known moons, and billions of small bodies. This last group includes asteroids, Kuiper belt objects, comets, meteoroids and interplanetary dust.

In wide terms, the charted regions of the Solar System consist of the Sun, four terrestrial inner planets, an asteroid belt composed of small rocky bodies, four gas giant outer planets, and a second belt, called the Kuiper belt, collected of icy objects. Beyond the Kuiper belt lies the scattered disc, the heliopause, and eventually the hypothetical Oort cloud.

In tennis, grass is grown on very hard-packed soil, and bounces may vary depend on how healthy the grass is, how recently it has been mowed, and the wear and tear of recent play. The most famous grass tennis court in the world is Centre Court at Wimbledon. Tennis, however, is generally played on clay courts, and only a a small number of regular tennis tournaments are played on a grass court. The exterior is less firm than rigid courts, causing the ball to spring back lower, and so players must reach the ball quicker. Due to high maintenance costs however, grass courts are now rare as they must be watered and mowed often, and take a longer time to dry after rain than hard courts.

Gerbera L., is a genus of ornamental plants from the sunflower family. It was named in honour of the German naturalist Traugott Gerber, a friend of Carolus Linnaeus. It has approximately 30 species in the wild; extend to South America, Africa, Madagascar, and tropical Asia. The first scientific description of a Gerbera was made by J.D. Hooker in Curtis Botanical Magazine in 1889 when he described Gerbera jamesonii, a South African species also known as Transvaal daisy or Barberton Daisy.

Gerbera species bear a large capitulum’s with striking, 2-lipped ray florets in yellow, orange, white, pink or red colors. The capitulum’s, which has the look of a single flower, is actually composed of hundreds of individual flowers. The morphology of the flowers varies depending on their position in the capitula. Gerbera is very popular and widely used as a decorative garden plant or as cut flowers. The domesticated cultivars are mostly a result of a cross between Gerbera jamesonii and another South African species Gerbera viridifolia.

Vacuum tubes

In electronics, a vacuum tube, electron tube, thermionic regulator, or just tap is a tool used to amplify, switch, otherwise alter, or create an electrical sign by calculating the progress of electrons in a low-pressure gap, often not tubular in type. Many devices called vacuum tubes are packed with low-pressure gas these are so-called soft valve as distinct starting the hard vacuum type, which have the interior gas force abridged as far as probable. Almost all depend on the thermal release of electrons, thus thermionic.

Vacuum tubes were the critical plans that enable the growth of electronics knowledge, leading to the growth and commercialization of such technology as radio distribution, television, radar, high loyalty sound imitation, large telephone network, current types of digital computer, and manufacturing process control.

Central nervous system

The central nervous system (CNS) represent the main part of the anxious system, counting the brain and the spinal thread. Together with the marginal nervous system, it has a basic role in the manage of performance. The CNS is restricted within the dorsal crack, with the brain within the cranial subcavity, and the spinal string in the spinal crater.

Since the burly hypothetical authority of cybernetics in the fifties, the CNS is conceive as a system dedicated to information meting out, where an suitable motor output is compute as a response to a sensory input. Yet, many clothes of investigate propose that motor action exist well before the maturation of the sensory system and then, that the mind only pressure performance without dictate it. This has bring the start of the CNS as an independent system.

Emotion, in its mainly common definition, is a complex psychophysical progression that arise suddenly, rather than during alert effort, and evoke either a positive or negative psychological answer and physical terms, often unconscious, related to feelings, perception or beliefs about element, matter or relatives between them, in realism or in the thoughts. An emotion is often differentiate from a sensation.

Emotion is difficult, and the tenure has no single generally conventional definition. The study of emotion is part of psychology, neuroscience, and, more lately, artificial cleverness.

Modern views recommend that emotion are brain state that rapidly give value to outcome and give a simple plan of act. Thus, sensation can be view as a type of calculation, a fast, automatic review that initiate suitable events.

Cascading Style Sheets
In web development, Cascading Style Sheets (CSS) is a stylesheet language use to express the arrangement of a article write in a markup language. Its most general function is to technique web pages written in HTML and XHTML, but the language can be useful to any kind of XML document, include SVG and XUL.

CSS is apply by both the authors and readers of web pages to describe colors, fonts, layout, and other aspect of document arrangement. It is considered primarily to facilitate the severance of document content from document production. This severance can improve content ease of access, provide more flexibility and control in the measurement of presentational character, and decrease density and replication in the structural content.

Data warehouse

A data warehouse is the major storehouse of an organization chronological data, its business memory. It contain the raw objects for management's conclusion support system. The vital factor leading to the use of a data warehouse is that a data forecaster can do complex query and study, such as data mining, on the information without slow down the ready systems.

A data warehouse might be new to find the day of the week on which a corporation sell the most widgets in May 1992, or how worker sick go away the week before the winter shatter differed stuck between California and New York from 2001-2005.

While prepared systems are optimized for effortlessness and speed of alteration through important use of database normalization and an entity-relationship reproduction, the data store is optimized for coverage and examination. Frequently data in data warehouse are deeply denormalised, summarised or store in a dimension-based representation.

Computer science

Computer science, or computing science, is the study of the academic basics of information and calculation and their completion and request in computer systems. Computer science has many sub-fields; some stress the computation of exact results, while others relay to property of computational harms. Still others hub on the challenge in implementing computations. For example, programming language assumption studies approach to relating computation, while computer programming applies specific programming language to resolve specific computational troubles with solutions. A further subfield, human-computer communication, focuses on the challenge in creation computers and computations helpful, working and commonly available to people.

Computer science is measured by some to have a much earlier association with arithmetic than lots of scientific disciplines. Early computer science was powerfully prejudiced by the work of mathematicians such as Kurt Gödel and Alan Turing, and there continues to be a useful exchange of thoughts between the two field in areas such as statistical logic, category assumption, domain assumption, and algebra.

Automated teller machine

An automated teller machine (ATM) is a programmed telecommunications device that provide the consumers of a financial organization with access to financial transactions in a public legroom without the need for a soul clerk or bank cashier. On most modern ATMs, the client is identified by insert a plastic ATM card with a magnetic strip or a artificial smartcard with a chip, that contain a single card number and some defense information, such as an finishing date or CVC. Security is provide by the customer ingoing a personal identification number (PIN).

Using an ATM, clientele can access their bank account in order to make cash withdrawal and check their account balance. Many ATMs also allow public to deposit cash or checks, move money between their bank accounts, pay bills, or acquire goods and services.

ATMs are known by a range of casual terms include automated banking machine, cash machine, hole-in-the-wall, cashpoint or Bancomat. The occasionally-used term ATM engine is an example of RAS pattern.

Embedded system
An embedded system is a special-purpose computer system planned to achieve a devoted function. Unlike a general-purpose computer, such as a personal computer, an embedded system perform one or a few pre-defined tasks, usually with very detailed supplies, and frequently includes task-specific hardware and automatic parts not typically found in a general-purpose computer. Since the system is devoted to exact tasks, design engineers can optimize it, dropping the size and cost of the produce. Embedded systems are often mass-produced, benefit from economy of scale.

Physically, embedded systems sort from portable devices such as digital watches and MP3 players, to large stationary installations like traffic lights, factory controller, or the system controlling nuclear power plants. In terms of intricacy embedded systems run from simple, with a single microcontroller chip, to very multifaceted with multiple units, peripherals and networks mount inside a large skeleton or field.

Nanotechnology is a field of applied science and technology cover a broad variety of topic. The main unify theme is the manage of matter on a scale lesser than 1 micrometre, normally between 1-100 nanometers, as well as the manufacture of strategy on this same length scale. It is a highly multidisciplinary field, sketch from fields such as colloidal discipline, device physics, and supramolecular chemistry. Much conjecture exists as to what new science and technology might answer from these lines of study. Some view nanotechnology as a advertising term that describes pre-existing lines of explore applied to the sub-micron size level.

Despite the obvious cleanness of this definition, nanotechnology actually encompass diverse lines of question. Nanotechnology cuts across many discipline, including colloidal science, chemistry, applied physics, material science, and even automatic and electrical engineering. It could variously be seen as an addition of existing sciences into the nanoscale, or as a recasting of existing sciences using a newer, more current term. Two main approach are used in nanotechnology: one is a "bottom-up" approach where materials and strategy are built from molecular components which accumulate themselves chemically using morality of molecular gratitude; the other being a "top-down" advance where nano-objects are construct from larger entity without atomic-level manage.

Search engine optimization

Search engine optimization (SEO) is the progression of civilizing the volume and excellence of traffic to a web site from search engines via "normal" ("natural" or "algorithmic") explore results. Usually, the previous a site is accessible in the search consequences, or the advanced it "ranks," the more searchers will appointment that site. SEO can also aim different kinds of exploration, including picture search, local exploration, and industry-specific upright search engines.

As a advertising strategy for rising a site's relevancy, SEO consider how hunt algorithms labor and what populace search for. SEO labors may engage a site's coding, arrangement, and organization, as well as fitting troubles that could put off search engine indexing program from fully spidering a site. Other, additional visible efforts may comprise adding sole content to a site, and creation sure that the satisfied is easily indexed by search engines and also appeal to human company.

A transformer is a tool that transfer electrical power from one route to another by magnetic mixture without require relative action between its parts. It regularly comprises two or more joined windings, and, in most cases, a center to focus magnetic instability.

An irregular voltage applied to one twisting creates a time-varying attractive flux in the center, which induce a electrical energy in the other windings. Varying the relation numeral of turns between major and derived windings determine the ratio of the contribution and production voltages, thus transform the voltage by step it up or down among circuits.

A codex is composed of many books; a book is of one scroll. It is called codex by way of metaphor from the trunks (codex) of trees or vines, as if it were a wooden stock, because it contains in itself a multitude of books, as it were of branches. In schools, in accounting and for taking notes wax tablets was the normal writing material. Wax tablets had the advantage of being reusable: the wax could be melted and a new text carved into the wax. The custom of binding several wax tablets together is a possible precursor for modern books .Also the etymology of the word codex suggests that it may have developed from wooden wax tablets.

The Colossus of Rhodes

From its building to its destruction lies a time span of merely 56 years. Yet the colossus earned a place in the famous list of Wonders.But even lying on the ground, it is a marvel, said Pliny the Elder. The Colossus of Rhodes was not only a gigantic statue. It was rather a symbol of unity of the people who inhabited that beautiful Mediterranean island Rhodes.

Let us first clear a misconception about the appearance of the Colossus. It has long been believed that the Colossus stood in front of the Mandraki harbor, one of many in the city of Rhodes, straddling its entrance. Given the height of the statue and the width of the harbor mouth, this picture is rather impossible than improbable. Moreover, the fallen Colossus would have blocked the harbor entrance. Recent studies suggest that it was erected either on the eastern promontory of the Mandraki harbor, or even further inland. Anyway, it did never straddle the harbor entrance.

Water pollution

Water pollution is a large set of unfavorable belongings upon water bodies such as lakes, rivers, oceans, and groundwater caused by human activities. Although natural phenomena such as volcanoes, algae blooms, storms, and earthquakes also cause main changes in water quality and the environmental status of water, these are not deemed to be pollution. Water pollution has many causes and characteristics. Increases in nutrient loading may lead to eutrophication. Organic wastes such as sewage inflict high oxygen demands on the getting water leading to oxygen depletion with potentially severe impacts on the whole eco-system. Industries discharge a variety of pollutants in their wastewater including grave metals, organic toxins, oils, nutrients, and solids. Discharges can also have thermal effects, especially those from power stations, and these too reduce the available oxygen. Silt-bearing runoff from many activities together with construction sites, deforestation and agriculture can reduce the penetration of sunlight through the water column, restricting photosynthesis and causing blanketing of the lake or river bed, in turn damaging ecological systems.

Pollutants in water consist of a wide spectrum of chemicals, pathogens, and physical chemistry or sensory changes.A lot of the chemical substances are toxic. Pathogens can apparently produce waterborne diseases in either human or animal hosts. Alteration of water's physical chemistry include acidity, conductivity, temperature, and eutrophication. Eutrophication is the fertilisation of surface water by nutrients that were previously scarce. Even many of the municipal water supplies in developed countries can present health risks.

Cooking is the act of preparing food for eating. The term cooking encompasses all methods of food preparation with non-heated methods. It encompasses a huge range of methods, tools and combinations of ingredients to change the taste or digestibility of food. It is the method of select, measuring and combining of ingredients in an planned procedure in an try to get the desired result. Factors affecting the finishing outcome include the inconsistency of ingredients, ambient conditions, tools, and the skill of the person doing the actual cooking.

The variety of cooking universal is a reflection of the many nutritional, aesthetic, agricultural, cultural and religious considerations that crash upon it.

Cooking frequently requires applying heat to a food, which regularly, though not always, chemically transforms it, thus varying its flavor, texture, appearance, and nutritional properties. There is archaeological proof of roasted foodstuffs, both animal and vegetable, in human campsites dating from the initial known use of fire, some 800,000 years ago

Tourism is travel for predominantly leisure or relaxation purposes, and also refers to the prerequisite of services in support of this act. Tourists are people who ,travel to and stay in places outside their common environment for not more than one consecutive year for leisure, business and other purposes not related to work out of an activity remunerated from within the place visited.

Tourism has become an enormously popular, global activity. As a service industry, tourism has frequent tangible and intangible elements. Major tangible elements include transportation, accommodation, and other apparatus of a hospitality industry. Major intangible elements relate to the purpose or inspiration for becoming a tourist, such as rest, relaxation, the opportunity to meet new people and experience other cultures, or simply to do something different and have an adventure.

Tourism is crucial for many countries, due to the income generated by the expenditure of goods and services by tourists, the taxes levied on businesses in the tourism industry, and the prospect for employment and economic advancement by working in the industry.

Edible flowers

Flowers provide less food than other major plants parts but they provide several important foods and spices. Flower vegetables include broccoli, cauliflower and artichoke. The most expensive spice, saffron, consists of dried stigmas of a crocus. Other flower spices are cloves and capers. Hops flowers are used to flavor beer. Marigold flowers are fed to chickens to give their egg yolks a golden yellow color, which consumers find more desirable. Dandelion flowers are often made into wine. Bee Pollen, pollen collected from bees, is considered a health food by some people. Honey consists of bee-processed flower nectar and is often named for the type of flower, e.g. orange blossom honey, clover honey and tupelo honey.

Hundreds of fresh flowers are edible but few are widely marketed as food. They are often used to add color and flavor to salads. Squash flowers are dipped in breadcrumbs and fried. Edible flowers include nasturtium, chrysanthemum, carnation, cattail, honeysuckle, chicory, cornflower, Canna, and sunflower. Some edible flowers are sometimes candied such as daisy and rose.

The fall of the Roman Empire in the fifth century A.D. saw the decline of the culture of ancient Rome. Due to lack of contacts with Egypt the papyrus became difficult to obtain and parchment started to be the main writing material.

In Western Roman Empire mainly monasteries carried on the Latin writing tradition, because first Cassiodorus in the monastery of Vivarium stressed the importance of copying texts, and later also St. Benedict of Nursia, in his Regula Monachorum promoted reading. The Rule of St. Benedict, which set aside certain times for reading, greatly influenced the monastic culture of the Middle Ages, and is one of the reasons why the clergy were the predominant readers of books. At first the tradition and style of the Roman Empire still dominated and only slowly the peculiar medieval book culture emerged.

Dengue hemorrhagic fever

DHF is a more severe form of dengue. It can be fatal if unrecognized and not properly treated. DHF is caused by infection with the same viruses that cause dengue. With good medical management, mortality due to DHF can be less than 1%.Dengue is transmitted to people by the bite of an Aedes mosquito that is infected with a dengue virus. The mosquito becomes infected with dengue virus when it bites a person who has dengue or DHF and after about a week can transmit the virus while biting a healthy person. Dengue cannot be spread directly from person to person.

The principal symptoms of dengue are high fever, severe headache, backache, joint pains, nausea and vomiting, eye pain, and rash. Generally, younger children have a milder illness than older children and adults.

Nature, in the broadest sense, is equivalent to the natural world, physical universe, material world or material universe. "Nature" refers to the phenomena of the physical world, and also to life in general. The term generally does not include manufactured objects and human interaction unless qualified in ways such as, e.g., "human nature" or "the whole of nature". Nature is also generally distinguished from the spiritual or supernatural. It ranges in scale from the subatomic to the galactic.

The word "nature" derives from the Latin word natura, or "the course of things, natural character."Natura was a Latin translation of the Greek word physis, which originally related to the innate way in which plants and animals grow of their own accord, and to the Greek word for plants generally.The concept of nature as a whole, the physical universe, is a more recent development that gained increasingly wide use with the advent of modern scientific method in the last several centuries.

2D computer graphics

The first advance in computer graphics was in the use of CRTs. There are two approaches to 2D computer graphics: vector and raster graphics. Vector graphics stores precise geometric data, topology and style such as: coordinate positions of points, the relations between points , and the color, thickness, and possible fill of the shapes. Most vector graphic systems can also use primitives of standard shapes such as circles, rectangles, etc.

Early vector-graphics displays were monochrome CRTs where the picture was drawn by the cathode ray being motivated about the screen along the required path.On a scanning display, a vector graphic image has to be transformed to a raster image to be viewed. Raster graphics is a uniform 2-dimensional grid of pixels. Each pixel has a specific value such as, for instance, brightness, color, transparency, or a combination of such values. A raster image has a finite resolution of a specific number of rows and columns. Standard computer displays shows a raster image of resolutions such as 1280 columnsx1024 rows of pixels.

The term wildlife refers to living organisms that are not in any way artificial or domesticated and which survive in natural habitats. Wildlife can refer to flora but more usually refers to fauna. Wildlife is a very general term for life in ecosystems. Deserts, rainforests, plains, and other areas including the most built-up urban sites all have distinct forms of wildlife.

Humans have historically tended to split civilization from wildlife in a number of ways; besides the obvious difference in vocabulary, there are differing expectations in the legal, social, and moral sense. This has been a reason for debate during recorded history. Religions have often declared certain animals to be sacred, and in modern times concern for the environment has aggravated activists to protest the exploitation of wildlife for human benefit or entertainment. Literature has also made use of the traditional human separation from wildlife.

Sound is an interruption of mechanical energy that propagates through matter as a wave. Sound is characterized by the properties of sound waves which are frequency, wavelength, period, amplitude and velocity or speed. Noise and sound often mean the same thing; when they differ, a noise is a useless sound. In science and engineering, noise is an undesirable component that obscures a signal.

Humans perceive sound by the sense of hearing. By sound, we usually mean the vibrations that travel through air and can be heard by humans. However, scientists and engineers use a wider description of sound that includes low and high frequency vibrations in air that cannot be heard by humans, and vibrations that travel through all forms of matter, gases, liquids and solids. The matter that supports the sound is called the medium. Sound propagates as waves of irregular pressure, causing local regions of compression and rarefaction. Particles in the medium are displaced by the wave and oscillate. The scientific study of sound is called acoustics.

Heat wave

A heat wave is a prolonged period of extremely hot weather, which may be accompanied by high humidity. There is no universal definition of a heat wave the term is relative to the usual weather in the area. Temperatures that people from a hotter climate believe normal can be termed a heat wave in a cooler area if they are outside the normal climate pattern for that area.
The term is applied both to routine weather variation and to extraordinary spells of heat which may occur only once a century. Severe heat waves have caused catastrophic crop failures, thousands of deaths from hyperthermia, and widespread power outages due to increased use of air conditioning.

Heat waves often occur for the period of the Dog Days of summer; indeed the French term canicule, denoting the general phenomenon of a heat wave, derives from the Italian canicula applied to the star Sirius, also known as the "Dog Star." Some regions of the globe are more susceptible to heat waves than others, such as Mediterranean-type climates with a summer dry spell which becomes much hotter than usual during certain years

Surreal humour

Surreal humour is a form of humour, stylistically linked to the artistic ambitions of the Surrealists, based on bizarre juxtapositions, absurd situations, and nonsense logic. A general element of surreal humour is the non-sequitur, in which one statement is followed by another with no logical progression.

Humour which we might now think surreal has been around at least since the nineteenth century. Lewis Carroll's Alice's Adventures in Wonderland and Through the Looking Glass both use illogic and absurdity for humorous effect. Many of Edward Lear's nonsense stories and poems are also principally surreal in approach. Thus, Lear's "The Story of the Four Little Children Who Went Round the World," is filled with contradictory statements and odd images planned to provoke amusement.

"After a time they saw some land at a distance; and when they came to it, they found it was an island made of water quite bounded by earth. Besides that, it was bordered by evanescent isthmuses with a great Gulf-stream running about all over it, so that it was perfectly beautiful, and contained only a single tree, 503 feet high."

In medicine, pulmonology is the specialty that deals with diseases of the lungs and the respiratory tract. It is called chest medicine and respiratory medicine in some countries and areas. Pulmonology is generally considered a branch of internal medicine, although it is closely related to intensive care medicine when dealing with patients requiring mechanical ventilation. Surgery of the respiratory tract is generally performed by specialists in cardiothoracic surgery . Chest medicine is not a specialty in itself but is an inclusive term which pertains to the treatment of diseases of the chest and contains the fields of pulmonology, thoracic surgery, and intensive care medicine. Pulmonology is concerned with the diagnosis and treatment of lung diseases, as well as secondary prevention.Physicans specializing in this area are called pulmonologists.

Surgical treatment in generally performed by the thoracic surgeon, generally after primary evaluation by a pulmonologist.Medication is the most important treatment of most diseases of pulmonology, either by inhalation or in oral form.Oxygen therapy is often necessary in severe respiratory disease.When this is insufficient, the patient might require mechanical ventilation.

Oral tradition and notation

Music is often conserved in memory and performance only, handed down orally, or aurally. Then the composer of music is no longer known this music is often classified as "traditional". Different musical traditions have dissimilar attitudes towards how and where to make changes to the original source material, from quite strict, to those which demand improvisation or modification to the music. In the Gambia, West Africa, the history of the country is passed orally through song.

When music is written down, it is generally notated so that there are instructions regarding what should be heard by listeners, and what the musician should do to perform the music. This is referred to as musical information, and the study of how to read notation involves music theory, harmony, the study of performance practice, and in some cases and understanding of historical presentation methods. Written notation varies with style and period of music. In Western Art music, the most common types of written notation are scores, which include all the music parts of an ensemble piece, and parts, which are the music notation for the individual performers or singers. In popular music, jazz, and blues, the regular musical notation is the lead sheet, which notates the melody, chords, lyrics, and structure of the music. Nonetheless, scores and parts are also used in popular music and jazz, mainly in large ensembles such as jazz "big bands."

Nature, in the broadest sense, is equivalent to the natural world, physical universe, material world or material universe. "Nature" refers to the phenomena of the physical world, and also to life in general. The term generally does not include manufactured objects and human interaction unless qualified in ways such as, e.g., "human nature" or "the whole of nature". Nature is also generally distinguished from the spiritual or supernatural. It ranges in scale from the subatomic to the galactic.

The word "nature" derives from the Latin word natura, or "the course of things, natural character."Natura was a Latin translation of the Greek word physis, which originally related to the innate way in which plants and animals grow of their own accord, and to the Greek word for plants generally.The concept of nature as a whole, the physical universe, is a more recent development that gained increasingly wide use with the advent of modern scientific method in the last several centuries.

Climate determinants

Over historic time spans there are a number of static variables that determine climate, including: latitude, altitude, proportion of land to water,and proximity to oceans and mountains. Other climate determinants are more dynamic: The thermohaline circulation of the ocean distributes heat energy between the equatorial and polar regions; other ocean currents do the same between land and water on a more regional scale.

Degree of vegetation coverage affects solar heat absorption, water retention, and rainfall on a regional level. Alteration in the quantity of atmospheric greenhouse gases determines the amount of solar energy retained by the planet, leading to global warming or global cooling. The variables which determine climate are numerous and the interactions complex, but there is general agreement that the broad outlines are understood, at least in so far as the determinants of historical climate change are concerned.

Genetic Engineering

Genetic engineering, genetic modification and gene splicing are terms for the process of manipulating genes, usually outside the organism's normal reproductive process. It involves the isolation, manipulation and reintroduction of DNA into cells or model organisms, usually to express a protein. The aim is to introduce new characteristics or attributes physiologically or physically, such as making a crop resistant to a herbicide, introducing a novel trait, or producing a new protein or enzyme. Examples can include the production of human insulin through the use of modified bacteria, the production of erythropoietin in Chinese Hamster Ovary cells, and the production of new types of experimental mice such as the OncoMouse for research, through genetic redesign.

Since a protein is specified by a segment of DNA called a gene, future versions of that protein can be modified by changing the gene's underlying DNA. One way to do this is to isolate the piece of DNA containing the gene, precisely cut the gene out, and then reintroduce the gene into a different DNA segment. Daniel Nathans and Hamilton Smith received the 1978 Nobel Prize in physiology or medicine for their isolation of restriction endonucleases, which are able to cut DNA at specific sites. Together with ligase, which can join fragments of DNA together, restriction enzymes formed the initial basis of recombinant DNA technology.
