Korea Space Launch Vehicle 1

Korea Space Launch Vehicle 1

The launch of South Korea 's first orbital launch satellite is planned for next week, although technical problems could delay the launch. Saturday South Korean officials said that the launch of the Korea Space Launch Vehicle 1 (KSLV-1), which is also known as Naro-1, is intended for August 11. The launch had been formerly scheduled for late July but it was delayed because of supplementary testing.

Yesterday the officials said that the launch could be further delayed to allow additional time for studying an engine firing test that took place last week. The launch vehicle, developed with technical support from Russia and using a lower stage originally developed for Russia 's Angara launcher, is calculated to launch small satellites into low Earth orbit. The KSLV-1 will launch from a new capability in the southwestern part of South Korea . The inaugural KSLV-1 launch will carry a small investigational satellite.

Endeavour Space shuttle

Endeavour Space shuttle

Space shuttle Endeavour is planned to land at Florida 's Kennedy Space Center today with a touchdown at 10:48 a.m. The shuttle would begin its go down from orbit with a de-orbit engine firing at 9:42 a.m. Weather conditions at Kennedy Space Center are forecast to be positive for landing, although a minor chance of rain is possible. A second chance exists for a landing in Florida today, beginning with a de-orbit engine firing at 11:17 a.m. , leading to a 12:22 p.m. touchdown.

No other shuttle hall sites are being measured for today landing. If weather prevents a landing today, alternating landing sites would be called up for tomorrow's landing opportunities. Thursday, Endeavour Space shuttle Commander Mark Polansky and Pilot Doug Hurley checked out the systems the shuttle will use as it returns home, ruling everything in outstanding shape. The crew also deployed two pairs of little satellites from containers in the shuttle's payload bay.

Microsoft-Yahoo deal to come in next 24 hours

0 comments
For more than a year now, rumors of a potential deal between Microsoft and Yahoo have ebbed and flowed. And it looks like the denouement of this epic tale may finally be upon us. A search and advertising deal between the two tech giants is expected to be announced within the next 24 hours, according to All Things D's Kara Swisher, who cites multiple unnamed sources.

It wasn't clear if a final deal had been signed, Swisher said Tuesday afternoon, but negotiations have apparently wrapped up. One sticking point late in the discussions came when Microsoft bristled at Yahoo's request for an upfront payment on the order of several hundred million dollars and revenue guarantees that would have meant billions of dollars over the course of the deal, according to Ad Age. But executives apparently worked through that kink and are now putting the finishing touches on an agreement.

According to All Things D and a separate report from Ad Age, Microsoft's search technology will power the search bars on Yahoo's pages. However, Yahoo will still sell search ads on its site and on Microsoft's Bing, according to the reports, which means Yahoo will be able to maintain the relationship with large advertisers interested in both display and search ads.

Yahoo has not responded to requests for comment on a potential deal. Microsoft declined to comment. Stay tuned for more as this story unfolds.

How to Boil the Water

0 comments

Choose a pot that's large enough to hold the amount of water you want to boil, and has a lid that fits. You might be tempted to use water that's already warm or hot from the tap, but this water has been sitting in your pipes for some time, getting stale. Use cold water if you're going to drink it or cook with it.

Don’t fill the pot all the way up. Keep in mind that anything you add to the boiling water will increase the volume, and plus, you’ll need to allow room for those bubbles to do their thing. Without enough room in the pot, for example, rice or pasta will boil over.Place the pot on the stove and turn the heat to high. If you want to speed up the process, put a cover on it

Check for steam escaping from under the lid, then lift the lid carefully to see how the water is doing.Look at the water. If large bubbles are rising from the bottom of the pot to the surface, the water is boiling. NOTE: Small bubbles that stay at the bottom or sides of the pot are air bubbles present in the water; they don't necessarily indicate that boiling is imminent. Wait for bubbles that rise to the top of the pot.

Business and Eco-System

0 comments
All businesses – all economic activities – depend on ecosystem services. Thus it is in the interests of business in general and companies in particular to help maintain and enhance those services.

Market-based instruments can achieve some environmental objectives for less economic cost than conventional approaches.Not surprisingly, business wants to find market-based ways to do this, given that business understands market mechanisms and knows them to be an extremely powerful lever.

Until recently, environmental NGOs have tended to be suspicious of this approach, partly because they tended to be suspicious of both business and markets, but also for the very good reason that it is often the poorest, most marginalized people who depend most directly on ecosystems, their services and their biodiversity for food, drinking water, clothing and shelter. Such people are rarely well equipped to participate in new markets.

Yet as NGOs have developed a more sophisticated understanding of markets and business, and as companies have become more knowledgeable about ecosystem services and their users, the two have begun to cooperate on solutions. It helps that business is beginning to understand and agree with the environmentalists' argument that conserving ecosystems and sustaining the services they provide is a pre-requisite for prosperity. Now we need to bring governments to this realization.

Fire Regime

0 comments
As devastating as it may appear, fire is a natural process, and Joshua Tree National Park has endured centuries of lightning-caused fires. Although fire in deserts has been less common than in forests because shrubs and trees are widely spaced in deserts and grasses not as abundant as in wetter areas.

The park maintains records of fires dating back to 1945. Most of these fires occurred between May 18 and September 20 when desert vegetation was very dry. Seventy-four percent of the fires were ignited by lightning. The remaining 26 percent were human caused.

The number and intensity of lightning fires has increased over the past 50 years. Before 1965 most lightning fires burned less than one-quarter acre. After 1965 more large fires and more frequent fires have been recorded. In 1979 the Quail Mountain fire burned 6,000 acres; in 1995 the Covington fire burned 5,158 acres. And in 1999, the largest fire in Joshua Tree’s history, the Juniper Complex fire burned 13,894 acres of slow-growing California junipers, pinyon pines, and Joshua trees.

Exotic grasses, such as red brome and cheatgrass, now represent up to 60 percent of the biomass from annuals. Resource managers believe the increased fuel loads provided by these exotic grasses are responsible for carrying lightning-ignited fires from plant to plant.

Desert plants do not need fire to reproduce and most are highly susceptible to fire. Shallow roots are easily burned and seeds lying on the ground waiting to germinate are destroyed. The desert does grow back but recovery after a fire is slow. Joshua trees can live for hundreds of years, and if one burns, it will take a hundred years for another to take its place. Even small shrubs like blackbrush may require 50 years to return to a burned area. Non-native grasses are also able to quickly recover after a fire and are usurping the habitat of native grasses.

The key to managing fire in Joshua Tree is in understanding how wildfires affect vegetation and wildlife in a desert environment where non-native grasses may have substantially altered the local ecology. Biologists are monitoring the long-term consequences of these newly arrived plants.

To help preserve and protect wildlife, scenery, and natural processes, each park develops its own Fire Management Plan. At Joshua Tree, we are revising our plan to provide for full suppression of all fires, including those naturally caused, until we have a better understanding of fire behavior and effects in the park. Although fire plays a beneficial, even a critical role, in some ecosystems, that may not be the case at Joshua Tree under these new conditions.

Snooping Protocals

0 comments
Snooping, in a security situation, is illegal access to another person's or company's data. Snooping can consist of informal observance of an e-mail that appears on another's computer screen or watching what someone else is typing. More complicated snooping uses software programs to distantly monitor bustle on a computer or network device. Snooping techniques, to monitor keystrokes, detain passwords and login information, and to catch e-mail and other private communications and data transmissions. Corporations sometimes snoop on workers legally to monitor their use of business computers and track Internet usage; governments may watch on persons to collect information and avert crime and terrorism. In a snooping system, all caches on the bus monitor the bus to determine if they have a copy of the block of data that is requested on the bus. Every cache has a copy of the sharing status of every block of physical memory it has. Multiple copies of a document in a multiprocessing environment typically can be read without any coherence problems; however, a processor must have exclusive access to the bus in order to write.
There are two types of snooping protocol
1.Write invalidate
Read-broadcast is not suitable for sequential sharing
It may prove beneficial in the single-producer, multiple-consumer situation
2.Write Update
Competitive Snooping is advantageous if there is sequential sharing

South Mission Beach

0 comments
South Mission Beach is bordered on the south by the Mission Bay Channel. It has, perhaps, the widest beach in the City. Recently, it has become known as a popular place to engage in sports such as beach volleyball and basketball following an extensive refurbishing of the courts. A popular game similar to baseball called "Over-The-Line" is allowed in a portion of this area.

Lifeguard Protection:

Lifeguards are staffed daily year round at the main lifeguard station at the foot of Avalon Court. In summer, additional lifeguards are staffed along the beach in seasonal lifeguard towers. Lifeguards are generally on duty from 9:00 a.m. to dusk; but check with lifeguards for specific staff hours.

Tornado

0 comments
Although tornadoes occur in many parts of the world, these destructive forces of nature are found most frequently in the United States east of the Rocky Mountains during the spring and summer months. In an average year, 800 tornadoes are reported nationwide, resulting in 80 deaths and over 1,500 injuries. A tornado is defined as a violently rotating column of air extending from a thunderstorm to the ground. The most violent tornadoes are capable of tremendous destruction with wind speeds of 250 mph or more. Damage paths can be in excess of one mile wide and 50 miles long. Once a tornado in Broken Bow, Oklahoma, carried a motel sign 30 miles and dropped it in Arkansas!

Angel Falls

0 comments
Angel Falls (indigenous name: Parakupa-vena or Kerepakupai merú) is the world's uppermost waterfall at 979 m (3,212 ft), with a clear drop of 807 m (2,647 ft). It is situated in the Canaima National Park, in the Gran Sabana region of Bolivar State, Venezuela at 5°58′03″N 62°32′08″W. The height of the falls is so great that previous to getting wherever near the ground, the water is vaporized by the strong winds and turned into fog. The base of the falls feeds into the Kerep River (alternately known as the Rio Gauya) which flows into the Churun River, a tributary of the Carrao River. In the indigenous Pemon language Angel Falls is called Kerepakupai merú meaning "waterfall of the deepest place".

The falls are occasionally referred to as Churun-meru, an error, because that name corresponds to another waterfall in the Canaima National Park. Churun in the Pemon language means "thunder".

Arizona Bison

0 comments
Buffalo, or Bison, are the largest living member in the cow family. Live adult weights range from 1,400 to 2,500 pounds for males and 750 to 1,600 pounds for females. Male buffalo have massive appearing front quarters with a large hump above the shoulders; these are covered with woolly hair up to 1.5 inches long that also covers the head and forelegs. This hair will turn tan with age and is two to five times thicker than hind quarter hair. The head has a broad triangular appearance with a beard. Calves are reddish-tan at birth and change to brown or black at three months. The hump and horns begin developing at six months age. Both males and females exhibit horns. Male horns can reach 20" long. Female horns are always smaller. Smell and hearing is acute, while eyesight is poor. Adult buffalo can run sprints of 35 mph for up to 1/4 of a mile and they can run longer distances at slower speeds. Buffalo are also capable of jumping over 6 foot high fences without touching the fence. While buffalo may live as long as 28 years, few attain the age of 12 to 15 years. They are gregarious and can form large herd groups. Herd groups are unstable and group composition changes constantly. Herd groups are dominated by a matriarchal female, except during breeding.

Adult buffalo eat approximately 35 pounds per day. Although local variations in forage availability and preferences occur, they will shift toward the most abundant forage; eating grasses, forbs, and browse.

Autobiography

0 comments
An autobiography, from the Greek αὐτός autos "self", βίος bios "life" and γράφειν graphein "to write",, is a biography written by the predicate or composed conjointly with a joint writer (styled "as told to" or "with"). The term was first used by the poet Robert Southey in 1809 in the English journal Quarterly Review, but the form goes back to ancient times. Biographers usually rely on a wide variety of documents and viewpoints; an autobiography however may be based completely on the writer's memory. Closely associated with autobiography (and sometimes difficult to exactly differentiate from it) is the form of memoir.

Toner-based printers

0 comments
Toner-based printers work by the Xerographic principle that is used in most photocopiers: by adhering toner to a light-sensitive print drum, then using still electricity to move the toner to the printing medium to which it is compound with heat and pressure.

The most ordinary type of toner-based printer is the laser printer, which uses accuracy lasers to reason toner adherence. Laser printers are known for high excellence prints, good print speed, and a low (Black and White) cost-per-copy. They are the most common printer for many general-purpose office applications, but are much less common as consumer printers due to their high first cost - though this cost is dropping.

Laser printers are obtainable in both color and monochrome varieties.

Another toner based printer is the LED printer which uses an array of LEDs in its place of a laser to cause toner bond to the turn out drum.

Recent research has also indicated that Laser printers emit potentially dangerous ultrafine particles, possibly causing health problems associated with respiration and reason pollution equal to cigarettes. The degree of particle emissions varies with age, model and design of each printer but is usually proportional to the amount of toner required. Furthermore, a well ventilated workspace would allow such ultrafine particles to scatter thus reducing the health side effect

Chinese New Year

0 comments
Chinese New Year is the longest and most important celebration in the Chinese calendar. The new year begins on the first day of the Chinese calendar, which usually falls in February, and the festivities continue for 15 days. During Chinese New Year celebrations, people wear red clothes, give children 'lucky money' in red envelopes and set off firecrackers. Chinese New Year ends with the lantern festival, where people hang decorated lanterns in temples and carry lanterns to an evening parade under the light of the full moon. The highlight of the lantern festival is often the dragon dance. The dragon can stretch over 30 metres long and is typically made of silk, paper and bamboo. In Sydney, more than 500,000 people crowd the streets to celebrate the Lunar New Year and all things Chinese.

Foundation of Designer Perfumes

1 comments

As with industry and the arts, perfume was to go through profound change in the nineteenth century. Changing tastes and the growth of modern chemistry laid the foundations of perfumery as we know it today. Alchemy gave way to chemistry and new fragrances were produced. The French Revolution had in no way diminished the flavor for perfume, there was even a fragrance called "Parfum a la Guillotine." Under the post-revolutionary government, people once again dared to convey a penchant for luxury goods, including perfume. A large amount of vanity boxes containing perfumes appeared in the 19th century.

Diamonds formed in cratons

0 comments
The conditions for diamond formation to happen in the lithospheric mantle occur at large depth corresponding to the aforementioned requirements of temperature and pressure. These depths are estimated to be in between 140–190 kilometers (90–120 miles) though rarely diamonds have crystallized at depths of 300-400 km (180-250 miles) as well. The rate at which temperature changes with rising depth into the Earth varies greatly in different parts of the Earth. In particular, under oceanic plates the temperature rises more rapidly with depth, beyond the range required for diamond formation at the depth required. The correct mixture of temperature and pressure is only found in the thick, ancient, and stable parts of continental plates where regions of lithosphere known as cratons exist. Long residence in the cratonic lithosphere allows diamond crystals to develop larger.

What does Integration generally mean by its word?

0 comments
Integration is a core model of advanced mathematics, particularly in the fields of calculus and mathematical analysis. Given a function f(x) of a actual variable x and an interval [a, b] of the real line, the integral is equal to the area of a region in the xy-plane bounded by graph of f, the x-axis, and the vertical lines x = a and x = b, by way of areas below the x-axis being subtracted.

The word "integral" may as well refer to the notion of antiderivative, a function F whose derivative is the given function f. In this casing it is called an indefinite integral, while the integrals discussed in this article are named definite integrals. Few authors maintain a distinction between antiderivatives and indefinite integrals.

Thunderbolt:

0 comments
A thunderbolt is a conventional expression for a release of lightning or a emblematic representation thereof. As a heavenly manifestation it has been a powerful symbol throughout history, and has appeared in many mythologies. Drawing from this influential association, the thunderbolt is often found in military symbolism and semiotic representations of electricity.
Lightning plays a role in many mythologies, often as the stick of a sky and storm god. As such, it is an unsurpassed method of dramatic instantaneous retributive devastation: thunderbolts as divine weapons can be found in most mythologies. The most well-known thunderbolt weapon in the West was that of Zeus or Jupiter. His thunderbolts were manufactured by Hephaestus/Vulcan Jupiter used his thunderbolts to strike down impious criminals and divine opponents.

Socialism

0 comments
Socialism refers to any of various economic and political concepts of collective ownership and administration of the means of production and sharing of goods and services some of which have been developed as more or less highly articulated and developed theory and/or praxis. In a Marxist or labor-movement definition of the term, socialism is a phase of society in Marxist theory transitional between capitalism and communism and distinguished by unequal distribution of goods and pay according to work done with the goal of creating a socio-economic system in which property and the distribution of wealth are subject to control by the community. This power may be exercised on behalf of the state, through a market, or through popular collectives such as workers' councils and cooperatives. As an economic system, socialism is often characterized by state, cooperative, or worker ownership of the means of production, goals which have been qualified to, and claimed by, a number of political parties and governments

An allergen is one substance that the body perceives as a risk, triggering a specific chain of events called an allergic cascade. The resistant system protects the body and at times incorrectly identifies a harmless allergen as a threat. The ensuing allergic effect causes symptoms, such as sneezing, coughing, runny nose, irritated throat, diarrhea, nausea, itching and pimples.

Power

0 comments

Mobile phones are generally obtaining power from batteries which can be recharged from mains power source. previously, the most common form of mobile phone batteries were nickel metal-hydride, as they have a low size and weight. Sometimes lithium-Ion batteries are used, as they are lighter and do not have the voltage depression that nickel metal-hydride batteries do. Many mobile phone manufacturers have now changed to using lithium-Polymer batteries as to oppose the older Lithium-Ion, the main advantages of this being even lower weight and the possibility to make the battery a shape other than strict cuboid. Mobile phone manufacturers have been experimenting with alternate power sources, including solar cells etc….

In addition to the battery, most cellphones require a small microchip, called a SIM Card, to operate.. Approximately the size of a one-cent postage stamp, the SIM Card is installed underneath the battery in the rear of the unit, and stores the phone's configuration data, and information about the phone itself, such as which calling plan the subscriber is using. When the subscriber removes the SIM Card, it can be re-inserted into another phone and used as normal this can be done easily..

Each SIM Card is activated by a unique numerical identifier ; once activated, that identifier is locked down and the card is permanently locked in to the activating network. Sim cards plays a major role in the mobile phones….

Banksia

0 comments

Banksia is a genus of approximately 80 species in the plant family Proteaceae. They are native to Australia, taking place in all but the most arid areas. Simply recognized by their characteristic flower spikes and fruiting "cones", Banksia are a well-known Australian wildflower and a well-liked garden plant. They grow up in forms varying from prostrate woody bushes to trees up to 25 metres tall. They are normally known as Banksias or Australian Honeysuckle Trees.

Banksias develop as trees or woody shrubs. The biggest trees, the Coast Banksia, B. integrifolia, and the River Banksia, B. seminuda, often grow over 15 metres tall, and may be up to 25 metres tall. Banksia species that raise as shrubs are usually erect, but there are several species that are prostrate, with branches that grow on or below the soil.

Aberrations

0 comments

A lens is a device for either concentrating or diverging light, usually produced from a piece of shaped glass. Lenses do not form perfect images, and there is always some degree of distortion or aberration introduced by the lens which causes the image to be an defective replica of the object. Careful design of the lens system for a exacting application ensures that the aberration is minimized. There are several different types of aberration which can influence image quality.

Sugarcane or Sugar cane (Saccharum) is a genre of between 6–37 species (depending on taxonomic interpretation) of tall grasses (family Poaceae, tribe Andropogoneae), native to warm temperate to steamy regions of the Old World. They have heavy, jointed fibrous stalks 2–6 m tall and sap rich in sugar. All the species interbreed, and the major commercial cultivars are complex hybrids.

Saccharum officinarum grown-up in Hawaii.There are 13 million hectares (32 million acres) of sugar cane plantations worldwide, with over 100 countries growing the crop. The peak twenty producing countries harvested 1200 million metric tons of sugar cane in 2002 , more than 6 times the amount of sugar beet produced. The major producers are Brazil, India, and China..

Solar System

0 comments

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 sort of their distances from the Sun, the planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Six of the eight planets are in turn orbited by natural satellites, usually termed "moons" after Earth's Moon, and each of the outer planets is encircled by planetary rings of dust and other particles. All the planets apart from Earth are named after gods and goddesses from Greco-Roman mythology. The three dwarf planets are Pluto, the largest known Kuiper belt object; Ceres, the largest object in the asteroid belt; and Eris, which lies in the scattered disc.

RAM

0 comments

Random access memory (usually known by its acronym, RAM) is a kind of data storage used in computers. It takes the form of integrated circuits that permit the stored data to be accessed in any order — that is, at random and without the physical movement of the storage medium or a physical reading head.

The key benefit of RAM over types of storage which need physical movement is that retrieval times are short and consistent. Short because no physical movement is required, and consistent because the time taken to retrieve a piece of data does not depend on its current distance from a physical head; it requires practically the equal amount of time to access any piece of data stored in a RAM chip.

Because of this speed and consistency, RAM is used as 'main memory' or primary storage: the working area used for loading, displaying and manipulate applications and data. In most personal computers, the RAM is not an essential part of the motherboard or CPU—it comes in the easily upgraded form of modules called memory sticks or RAM sticks about the size of a few sticks of chewing gum, which can be quickly detached and replaced when they become damaged or too small for current purposes. A smaller amount of random-access memory is also integrated with the CPU, but this is usually referred to as "cache" memory, rather than RAM.

The disadvantage of RAM over physically moving media is cost, and the loss of data when power is turned off. For these reasons, almost all PCs have disc storage as "secondary storage". Small PDAs and music players (up to 8 GiB in Jan 2007) may allot with disks, but rely on flash memory, to retain data between sessions of use.

An operating system (OS) is a colection of computer programs that manage the hardware and software resources of a computer.An operating system processes unprocessed system and user input and responds by allocating and managing tasks and interior system resources as a service to users and programs of the system. At the establishment of all system software, an operating system performs basic tasks such as controlling and allocating memory, prioritizing system requests, controlling input and output devices, facilitating networking and managing file systems. mainly operating systems come with an application that provides an interface to the OS managed resources. These applications have been command line interpreter as a basic user interface, but more recently have been implemented as a graphical user interface (GUI) for easiness of operation. Operating Systems themselves have no user interfaces, and the user of an OS is an application, not a person. The operating system forms a platform for other system software and for application software. Microsoft Windows, Linux, and Mac OS are some of the most popular OS's

Network Monitoring

0 comments
The term network monitoring describes the use of a system that always monitors a computer network for slow or failing systems and that notifies the network administrator in case of outages via email, pager or other alarms. It is a subset of the functions occupied in network management.

While an interruption detection system monitors a network for threats from the outside, a network monitoring system monitors the network for troubles due to overloaded and/or crashed servers, network connections or other devices.

usually measured metrics are response time and availability (or uptime), although both consistency and reliability metrics are starting to increase popularity.Status request failures, such as when a connection cannot be established, it times-out, or the document or message cannot be retrieved, usually produce an action from the monitoring system. These actions vary: an alarm may be sent out to the resident (SMS, email,...) sysadmin, automatic failover systems may be activated to remove the disturbed server from duty until it can be repaired, etcetera.Monitoring the performance of a network uplink is also known as network traffic measurement, and more software is listed there.

Landscape Archaeology

0 comments

Landscape archaeology refers to a method of studying past people and their material culture in the context of the wider environment. The landscape may be large, such as a wide marshy river delta or small, like a back garden. It is often employed in cultural resources management to recognize exposed sites. Landscape archeology addresses the difficult issues of the behavior that people intentionally and deliberately shaped the land around them.

The inquiry of what exactly constitutes a site has been discussed at length by generations of archaeologists.. Areas of examination are not restricted to the boundaries of an excavation but can instead stretch for many miles. Excavation is typically impractical on such a scale and landscape archaeologists hub on the visible features that can be recognized and recorded on the ground surface to create a picture of human activity across a region.

Archaeological features covered just below the surface often leave tell-tale 'lumps and bumps', plough action in fields can lift archaeological material to the surface, in areas of restricted human activity, worked flint scatters can survive untouched for many centuries and standing buildings and field boundaries can be of great antiquity yet archaeologically unexamined.

Information Technology

0 comments

Information technology (IT), is the study, design, development, implementation, support or administration of computer-based information systems, particularly software applications and computer hardware.In short, IT deals with the use of electronic computers and computer software to transfer, store, protect, process, transmit and get back information, securely.

In this definition, the term "information" can frequently be replaced by "data" without loss of meaning. Recently it has become popular to widen the term to explicitly consist of the field of electronic communication so that people tend to use the abbreviation ICT (Information and Communication Technology). Strictly speaking, this name contains some redundancy.

Today, the term Information Technology has distended to encompass many aspects of computing and technology, and the term is more identifiable than ever before. The Information Technology umbrella can be quite large, covering many fields. IT professionals achieve a variety of duties that range from installing applications to designing complex computer networks and information databases.

Hard Disk

0 comments

A hard disk is a non-volatile storage device which stores digitally programmed data on rapidly rotating platters with magnetic surfaces. Strictly speaking, "drive" refers to a device that drives (removable) media, such as a tape drive or (floppy) disk drive, although a hard disk contains fixed (non-removable) media. Recently the hard disk has become more commonly known as the "hard drive".

Hard disks were initially developed for use with computers. In the 21st century, applications for hard disks have extended beyond computers to consist of digital video recorders, digital audio players, personal digital assistants, digital cameras, and video game consoles. In 2005 the first mobile phones to contain hard disks were introduced by Samsung Group and Nokia. The need for large-scale, reliable storage, independent of a particular device, led to the beginning of configurations such as RAID, hardware such as network attached storage (NAS) devices, and systems such as storage area networks (SANs) for efficient access to large volumes of data.

Geography

0 comments

Geography is the study of the earth and its features and of the circulation of life on the Earth. A literal transformation would be "to describe the Earth". The first person to use the word "geography" was Eratosthenes (275-195 B.C.). Four historical civilization in geographical research are the spatial analysis of natural and human phenomena, area studies, study of man-land relationship, and investigate in earth sciences. Nonetheless, modern geography is an all-inclusive discipline that foremost seeks to understand the world and all of its human and natural complexities-- not merely where things are, but how they have changed and come to be. It is said to be the "mother of all math" and "the synthesizer of information." Geography is mainly divided into two main branches - human geography and physical geography.

Conventionally, geography as well as geographers has been viewed as the same as cartography and people who study place names. Although many geographers are capable in toponymy and cartography, this is not their main preoccupation. Geographers study the spatial and temporal allotment of phenomena, processes and feature as well as the interaction of humans and their environment. As space and place persuade a variety of topics such as economics, health, climate, plants and animals, geography is highly interdisciplinary.

Education System

0 comments

Schooling occurs when group or a society or an individual sets up a curriculum to educate people, usually the young. Schooling can become systematic. Sometimes education systems can be used to promote doctrine or ethics as well as knowledge, and this can lead to abuse of the system.

Life-long or adult education have become extensive in many countries. However, education is still seen by many as something aimed at children, and adult education is often branded as adult learning or ultimate learning.

Adult education takes on several forms, from formal class-based learning to self-directed learning. Lending libraries provide cheap informal access to books and other self-instructional materials. Many adults have also taken advantage of the rise in computer ownership and internet access to further their casual education.

Dot matrix printer

0 comments

Unlike a typewriter or daisy wheel printer, letters are tired out of a dot matrix, and thus, varied fonts and random graphics can be produced. Because the printing involves mechanical pressure, these printers can create carbon copies and carbonless copies. A dot matrix printer or impact matrix printer refers to a type of computer printer with a print head that runs back and forth on the page and prints by impact, outstanding an ink-soaked cloth ribbon beside the paper, much like a typewriter.

Each dot is formed by a tiny metal rod, also called a "wire" or "pin", which uses the power of a tiny electromagnet or solenoid to drive it forward, either directly or through small levers .Facing the ribbon and the paper is a small guide plate (often made of an artificial jewel such as sapphire or garnet) pierced with hole to provide as guides for the pins. The moving portion of the printer is called the print head, and prints one line of text at a time.The majority dot matrix printers have a single vertical line of dot-making apparatus on their print heads; others have a few interleaved rows in order to improve dot density.

These machines can be highly durable, but eventually wear out. Ink invades the direct plate of the print head, causing grit to adhere to it; this grit slowly causes the channels in the guide plate to wear from circles into ovals or slots, providing less and less correct guidance to the printing wires. After about a million characters, even with tungsten blocks and titanium pawls, the printing becomes too unclear to read.

Biography

0 comments
Biography (from the Greek words bios meaning "life", and graphein meaning "write") is a type of literature and further forms of media such as film, based on the written accounts of individual lives. While a biography may focus on a subject of fiction or non-fiction, the term is frequently in reference to non-fiction. Pat Shipman however, says "I think a good biographer has to write fiction some of the time to make apparent a significant event in someone's life." This is sometimes debated. As opposed to a profile or curriculum vitae, a biography develops a complex analysis of personality, highlighting different aspects of it and including intimate details of experiences. A biography is more than a list of distant facts like birth, education, work, relationships and death. It also delves into the emotions of experiencing such events.

Ancient Greeks developed the biographical tradition which we have inherited, although until the 5th century AD, when the word 'biographia' first appears, in Damascius' Life of Isodorus, biographical pieces were called simply "lives" ("bioi"). It is quite likely that the Greeks were drawing on a pre-existing eastern tradition; certainly Herodotus' Histories contains more exhaustive biographical information on Persian kings and subjects than on anyone else, implying he had a Persian source for it.

Automobile

0 comments
An automobile (also motor car or simply car) is a wheeled traveler vehicle that carries its own motor. Most definitions of the term specify that automobiles are designed to run mostly on roads, to have seating for one to eight people, to typically have four wheels, and to be constructed principally for the transport of people rather than goods.However, the term is far from precise.

The economics of personal automobile ownership go away from the initial cost of the vehicle and includes repairs, maintenance, fuel, depreciation, the cost of borrowing, parking fees, tire replacement, taxes and insurance.The capability for humans to travel rapidly from place to place has far reaching implications for the nature of our society. People can now live faraway from their workplaces, the design of our cities is determined as much by the need to get vehicles into and out of the city as the nature of the buildings and public spaces within the city.

Multimedia

0 comments
Multimedia is media that uses multiple forms of information content and information processing to inform or amuse the audience. Multimedia referd to the use of electronic media to store and experience multimedia content. Multimedia is similar to traditional mixed media in fine art, but with a broader scope. The term rich media is identical for interactive multimedia. Multimedia means that computer info can be represented through audio, graphics, image, video and animation in addition to traditional media (text and graphics). Hypermedia can be considered one particular multimedia application.

Multimedia may be generally divided into linear and non-linear categories. Linear dynamic content progresses without any navigation control for the observer such as a cinema presentation. Non-linear content offers user interactivity to control progress as used with a computer game or used in self-paced computer based training. Non-linear content is also known as hypermedia content.

Multimedia presentations can be exist or recorded. A recorded presentation may allocate interactivity via a navigation system. A live multimedia presentation may allow interactivity via interaction with the presenter or performer.

A ferry is a form of transport, characteristically a boat or ship, but also other forms, carrying passengers and sometimes their vehicles. Ferries are also used to carry shipment(in Lorries and sometimes empowered freight containers) and even railroad cars. Most ferries manage on regular, everyday, return services. A foot-passenger ferry with a lot of stops, such as in Venice, is also known as waterbus or water taxi .
Ferries form a part of the public transport systems of many water's edge cities, allow direct transit between points at a capital cost much lower than bridges or tunnels.

Trailers

0 comments
A Trailer is normally an unpowered vehicle pulled by a powered vehicle, because powered trailers are more explicitly called potrailers. Commonly, the term trailer refers to such vehicles used for transport of goods and materials.

Trailer winches are intended to load (or unload) boats and other cargo to and from a trailer. The are invented a ratchet mechanism and cable. The handle on the ratchet mechanism is twisted to tighten or loosen the tension on the winch cable. There are both manual and motorized trailer winches

Popup campers are trivial, aerodynamic trailers that can be towed by a small car, such as the BMW Air Camper and the Coleman Bayside. They are built to be shorter than the tow vehicle, minimizing drag.

Others range from two-axle campers that can be pulled by most mid-sized pickups to trailers that are as long as the host country's law allows for drivers without individual permits. Larger campers tend to be fully integrated leisure vehicles, which often are used to tow single-axle dolly trailers to allow the driver to bring small cars on their travels.

Planet

0 comments
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.

Fresh skin-care tips

0 comments

Select fresh, organically grown fruit and vegetables for the highest benefits. Avoid making more than you require for a single application.Clean and sanitize all countertops and mixing utensils ahead of making any of the recipes. Clean all fruit and vegetables before using as ingredients. Leave all ingredients out of the fridge for up to an hour before integration. Don't let fruit acquire any warmer than room temperature.

Fresh fruit and vegetables are especially high in acids. If you apply anything to your skin and encounter a burning sensation, take out immediately and apply cool water.If you are in the care of a dermatologist and on acne medications, please consult with your physician first.

Camera

0 comments

A camera is a device used to take pictures, either alone or in sequence, with or without sound, such as with video cameras. The name is consequent from camera obscura, Latin for "dark chamber", an early mechanism for projecting images in which an whole room functioned much as the internal workings of a modern photographic camera, except there was no way at this time to record the image little of manually tracing it. Cameras may work with the visual spectrum or other portions of the electromagnetic spectrum.

Every camera consists of some kind of enclosed chamber, with an opening or aperture at one end for light to enter, and a recording or viewing surface for capturing the light at the other end. This diameter of the aperture is often controlled by an diaphragm mechanism, but some cameras have a fixed-size opening.

Video and digital cameras use electronics, usually a charge coupled device or sometimes a CMOS sensor to detain images which can be transferred or stored in tape or computer memory within the camera for later playback or processing.Traditional cameras capture light onto photographic film or photographic plate.

A video camera is a group of movie camera which stores images onto magnetic tape.Cameras that capture many images in sequence are known as movie cameras or as ciné cameras in Europe; those designed for distinct images are still cameras. However these categories overlap, as still cameras are often used to capture moving images in special belongings work and modern digital cameras are often able to trivially switch between still and motion recording modes.

Linux

Linux is a computer operating system like unix,windows etc.. Linux is one of the most famous examples of free software and open source development; its underlying source code can be freely modified, used, and redistributed by anyone.The Linux kernel was first released to the community on 17 September 1991, for the Intel x86 PC architecture. The kernel was enlarged with system utilities and libraries from the GNU project to create a usable operating system, which later led to the alternate term GNU/Linux.Linux is now packaged for different uses in Linux distributions, which contain the sometimes customized kernel along with a variety of other software packages tailored to different requirements.

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.

The Bay of Bengal is a bay that forms the northeastern ingredient of the Indian Ocean. It resembles a triangle in form, and is bordered on the east by Malay Peninsula, and on the west by India. On the northern pour of the "bay" lies the Bengal region, comprising the Indian state of West Bengal and the country of Bangladesh, thus the name. The southern extremes arrive at the island country of Sri Lanka, and the Indian Union Territory of Andaman and Nicobar Islands.

The Bay of Bengal occupies an region of 2,172,000 km². It is bounded by India and Sri Lanka to the West, Bangladesh to the North, and Myanmar and the southern part of Thailand to the East. Its southern border extends as an imaginary line from Dondra Head at the southern end of Sri Lanka to the northern tip of Sumatra. A number of huge rivers – Ganges, Brahmaputra, Irrawaddy, Godavari, Mahanadi, Krishna and Cauvery – flow into the Bay of Bengal. Among the vital ports are Yangon, Kolkata/Calcutta, Chittagong, Cuddalore, Kakinada, Machlipatnam, Madras, Paradip and Vishakapatnam.

In medicine, prevention is any action which reduces the burden of humanity or morbidity from illness. This takes place at primary, secondary and tertiary prevention levels.

Primary prevention avoids the growth of a disease. Most population-based health support actions are primary preventive measures.Secondary prevention activities are intended at early disease detection, thereby increasing opportunities for interventions to prevent progression of the disease and emergence of symptoms.Tertiary prevention reduces the negative impact of an already recognized disease by restoring function and dipping disease-related complications.

Abstract art

0 comments
Abstract art is now usually understood to mean art that does not depict objects in the natural world, but instead uses colour and form in a non-representational way.In the very early 20th century, the term was more often used to describe art, such as Cubist and Futurist art, that depicts real forms in a simplified or rather reduced way—keeping only an allusion of the original natural subject. Such paintings were often claimed to capture amazing of the depicted objects' immutable intrinsic qualities rather than its external appearance. The more precise terms, "non-figurative art," "non-objective art," and "non-representational art" avoid any possible ambiguity.

USB Drives

0 comments
USB drives means Universal Serial Bus.USB flash drives also known as USB drives, key drives, pen drives or thumb drives.USB drives are NAND-type flash memory data storage devices incorporated with a USB interface. They are typically small, lightweight, detachable and rewritable. As of April 2007, memory capacities for USB Flash Drives currently are sold from 32 megabytes up to 64 gigabytes .Capacity is limited only by current flash memory densities, although cost per megabyte may increase quickly at higher capacities due to the expensive components.

USB flash drives offer possible advantages over other portable storage devices, particularly the floppy disk. They are more compact, generally faster, hold more data, and are more consistent than floppy disks. These types of drives use the USB mass storage standard, supported natively by recent operating systems such as Linux, Mac OS X, Unix, and Windows.

Wi-Fi

0 comments
Wi-Fi is a product originally licensed by the Wi-Fi Alliance to illustrate the embedded technology of wireless local area networks (WLAN) based on the IEEE 802.11 specifications. Wi-Fi was developed to be used for mobile computing devices, such as laptops in LANs, but is now increasingly used for more services, together with Internet and VoIP phone access, gaming, and basic connectivity of consumer electronics such as televisions, DVD players, and digital cameras. More standards are in advance that will allow Wi-Fi to be used by cars on highways in support of an intellectual Transportation System to increase safety, gather statistics, and enable mobile commerce.

A person with a Wi-Fi enabled mechanism such as a pc, cell phone or PDA can connect to the Internet when in proximity of an access point. The region enclosed by one or several access points is called a hotspot. Hotspots can range from a single room to many square miles of overlapping hotspots. Wi-Fi can also be used to create a mesh network. Both architectures are used in community networks.

Computer Networking

0 comments
Computer networking is the engineering discipline anxious with communication between computer systems. Such communicate systems comprise a computer network and these networks generally involve at least two devices able of being networked with at least one usually being a computer. The devices can be separated by a small number of meters or nearly unlimited distances. Computer networking is sometimes considered a sub-discipline of telecommunications, and sometimes of computer science, information technology and computer engineering. Computer networks rely a lot upon the abstract and practical application of these scientific and engineering disciplines.

A computer network is any set of computers connected to each other. Examples of networks are the Internet, a wide area network that is the largest to always exist, or a little home local area network (LAN) with two computers connected with standard networking cables connecting to a network interface card in each computer.

Robotics

0 comments
Robotics is the science and technology of robots, their design, manufacture, and application.Robotics requires a functioning knowledge of electronics, mechanics, and software. A person working in the field is a roboticist. The word robotics was first used in publish by Isaac Asimov, in his science fiction short story "Runaround" (1941).

Although the exterior and capabilities of robots fluctuate enormously, all robots share the features of a mechanical, movable structure under some form of control. The chain is warped of links ,actuators and joints which can allow one or more degrees of freedom. Most contemporary robots use open serial chains in which each link connects the one before to the one after it. These robots are called serial robots and often resemble the human arm. A few robots, such as the Stewart platform, exploit closed parallel kinematic chains. Other structures, such as those that mimic the mechanical structure of humans, different animals and insects, are comparatively rare. However, the development and use of such structures in robots is an dynamic area of research. Robots used as manipulators have an end effector mounted on the last link. This end effector can be anything from a welding mechanism to a mechanical hand used to manipulate the environment.

Outline business strategy
The marketing program represents the heart of a company's business strategy. The financial section of business strategy presents information about the company’s fiscal status and also specifies the amount of money is being spent to activate the company and how much money is being brought in as a result of product/service sales. You can also record the company's assets and liabilities. The suggested page lengths for a comprehensive plan are given in parenthesis after each section's heading within the outline. A small, straightforward business should work within the minimum page lengths whereas a large, complex business seeking a substantial external investment might hit the maximum page lengths. Work on the assumption that whoever reads your plan will be completely unknown with your business or project and will be seeking answers to relatively basic questions and key issues. You can also refer to other papers in this series which cover insights into business planning, financial planning, cashflow forecasting, strategic planning, devising business strategies and managing working capital for further information on business planning issues. Finally, you should review the contents of the Business Plan Guide.

Art


The term art is generally used to explain a scrupulous type of creative production generated by human beings, and the term normally implies some degrees of aesthetic values. An artist makes a work of art for various purposes, such as creating an understanding for others or as part of a sacrament. There is no general agreed-upon definition of art, since defining the boundaries of "art" is subjective, but the impetus for art is often known as human creativity.

Art is that which is made with the intention of stimulating the human senses as well as the human mind and or spirit. An artwork is normally assessed in quality by the amount of stimulation it brings about. The impact it has on people, the amount of people that can be related to it, the degree of their appreciation, and the effect or influence it has or has had in the past, and all accrue to the 'degree of art.' Most art that are widely considered to be "masterpieces" possess these attributes.

Surgery

0 comments

Surgery is done to remove cancer cells and surrounding tissue. It is often combined with radiation therapy and chemotherapy. After surgery, the body needs extra calories and protein for wound healing and recovery. At this time, many people have some pain and fatigue. In addition, they may be unable to eat a normal diet because of surgery-related side effects. The body's ability to use nutrients may also be changed by removal of any part of the mouth, esophagus, stomach, small intestine, colon, or rectum.

Nutrition suggestions for people recovering from cancer surgery: If you've had surgery, remember that many side effects will go away within a few days of the operation. Certain drugs, self-care practices, and changes in diet can help lessen any side effects you may have. If they persist, be sure to tell your doctor, nurse, dietitian, or other member of your health care team.

The Lighthouse of Alexandria

0 comments

Of the Seven Wonders of the Ancient World, only one had a practical use in addition to its architectural elegance: The Lighthouse of Alexandria. For sailors, it ensured a safe return to the Great Harbor. For architects, it meant even more: it was the tallest building on Earth. And for scientists, it was the mysterious mirror that fascinated those most. The mirror which reflection could be seen more than 50 km (35 miles) off-shore.

On the ancient island of Pharos, now a promontory within the city of Alexandria in Egypt.

Shortly after the death of Alexander the Great, his commander Ptolemy Soter assumed power in Egypt. He had witnessed the founding of Alexandria, and established his capital there. Off of the city's coast lies a small island: Pharos. Its name, legend says, is a variation of Pharaoh's Island. The island was connected to the mainland by means of a dike - the Heptastadion - which gave the city a double harbor. And because of dangerous sailing conditions and flat coastline in the region, the construction of a lighthouse was necessary.

Everybody longs for that healthy glow, for sparkling eyes and shiny hair that bounces with every step. Millions of dollars are spent every year in beauty products to make skin that much clearer, wrinkles that less visible and lips pout that much more. And while there are cosmetics that do work, you shouldn’t underestimate the value of natural beauty products. Perspiration and body odor have been of concern for many of us who wish to present a beautiful body to others. Deodorants hide the smell with fragrance. Taking care of your body means taking care of your self and for that you don’t need to put superfluous efforts or you don’t need to put extra hour in your work schedule. You need to regulate your life style, discover the ways of living, and to monitor yourself with proper care.

Home Decorations

0 comments



Art is often seen as belonging to one social class and excluding others. In this context, art is seen as a high-status activity associated with wealth, the ability to purchase art, and the leisure required to enjoy it. The palaces of Versailles or the Hermitage in St. Petersburg with their vast collections of art as home decorations, amassed by the fabulously wealthy royalty of Europe exemplify this view. Collecting such Vases is the preserve of the rich.

However, there is a tradition of artists bringing their vision down to earth, and inhabiting a mundane, even poverty stricken, world. The life of Vincent van Goth is a classic example of this starving artist tradition. It hardly needs to be mentioned, however, that few find such a state of existence desirable, and that one of the near-defining characteristics of artists is a desire to be seen universally, if not always to be understood. Picture Frames are used for home decorations.

Before the 13th century in Europe, artisans were considered to belong to a lower caste, since they were essentially manual laborers. After Europe was re-exposed to classical culture during the Renaissance, particularly in the nation states of what is now Italy, artists gained an association with high status. However, institutions of power as marks of their own status have always used arrangements of “fine” and expensive goods. This is seen in the 20th and 21st century by the commissioning or purchasing of art by big businesses and corporations as decoration for their offices.

Water Treatment Systems

0 comments

Reverse osmosis systems, water filters, water treatment systems and distillers all promise sparkling, clean water, but how do you know which one is really best? With a little research, you can find the ideal water treatment system for you.

Water is vital to everyday life, and throughout history people have devised systems to make getting and using it more convenient. Water is treated to achieve water quality objectives for the end uses. In the case of potable water supply, water is treated to minimize risk of infectious disease transmittal, risk of non-infectious illness, and create a palatable water flavor.

Water treatment systems are designed and built to provide adequate water pressure, and flow rates to meet various end-user needs such as fire suppression, showering, and irrigation.

yachting

0 comments
These days, yacht racing and dinghy racing are common participant sports around the developed world, particularly where favorable wind conditions and access to reasonably sized bodies of water are available. Most yachting is conducted in salt water, but smaller craft can be - and are - raced on lakes and even large rivers.

Whilst there are many different types of racing vessels, they can generally be separated into the larger yachts, which are larger and contain facilities for extended voyages, and smaller harbor racing craft such as dinghies and skiffs.

Dinghy races are conducted on sheltered water on smaller craft, usually designed for crews of between one and three people. They are almost all equipped with one mast. Some have only one triangular sail, but most have two configured as a sloop, and usually carry a spinnaker, a large, bulging sail designed for sailing "with the wind".

Taj Mahal

0 comments

Located at the city of Agra in the State of Uttar Pradesh, the Taj Mahal is one of the most beautiful masterpieces of architecture in the world. Agra, situated about 200 km south of New Delhi, was the Capital of the Mughals (Moguls), the Muslim Emperors who ruled Northern India between the sixteenth and nineteenth centuries. The Mughals were the descendents of two of the most skilled warriors in history: the Turks and the Mongols. The Mughal dynasty reached its highest strength and fame during the reign of their early Emperors, Akbar, Jehangir, and Shah Jehan.

It was Shah Jehan who ordered the building of the Taj, in honor of his wife, Arjumand Banu who later became known as Mumtaz Mahal, the Distinguished of the Palace. Mumtaz and Shah Jehan were married in 1612 and, over the next 18 years, had 14 children together. The Empress used to accompany her husband in his military campaigns, and it was in 1630, in Burhanpur, that she gave birth to her last child, for she died in childbirth. So great was the Emperor love to his wife that he ordered the building of the most beautiful mausoleum on Earth for her.

Although it is not known for sure who planned the Taj, the name of an Indian architect of Persian descent, Ustad Ahmad Lahori, has been cited in many sources. As soon as construction began in 1630, masons, craftsmen, sculptors, and calligraphers were summoned from Persia, the Ottoman Empire, and Europe to work on the masterpiece. The site was chosen near the Capital, Agra on the southwest bank of the River Yamuna. The architectural complex is comprised of five main elements: the Darwaza or main gateway, the Bageecha or garden, the Masjid or mosque, the Naqqar Khana or rest house, and the Rauza or the Taj Mahal mausoleum. The actual Tomb is situated inside the Taj.

The Great Wall of China

0 comments

The Great Wall started as earth works thrown up for protection by different States. The individual sections weren't connected until the Qin dynasty (221-206 B.C.). Qin Shihuangdi, First Emperor of Qin began conscripting peasants, enemies, and anyone else who wasn't tied to the land to go to work on the wall. He garrisoned armies at the Wall to stand guard over the workers as well as to defend the northern boundaries. The tradition lasted for centuries. Each dynasty added to the height, breadth, length, and elaborated the design mostly through forced labor.

It was during the Ming dynasty (1368-1644) that the Wall took on its present form. The brick and granite work was enlarged and sophisticated designs were added. The watch towers were redesigned and modern canon were mounted in strategic areas. The Portuguese had found a ready market for guns and canon in China, one of the few items of trade that China didn't already have in abundance. The Ming Emperors, having overthrown the Hun dominance and expelled their Mongol rulers of the North devoted large portions of available material and manpower to making sure that they didn't return.

Throughout the centuries, armies were garrisoned along the length of the Wall to provide early warning of invasion and a first line of defense. Great piles of straw and dung used to build signal fires have been found during excavations. There must have been small garrison towns spotted along the length. There weren't many farms or trade towns to provide ease, relaxation and food. The supply trails were over mountains along narrow paths. To bring supplies to the top, ropes were slung over posts set in the Chinese side of the wall and baskets were hauled up hand over hand. Supplies must have always been short and chancy, particularly in the winter.

The Wall served well. Only when a dynasty had weakened from within were invaders from the north able to advance and conquer. Both the Mongols (Yuan Dynasty, 1271-1368) and the Manchurians (Qing Dynasty,1644-1911) were able take power, not because of weakness in the Wall but because of weakness in the government and the poverty of the people. They took advantage of rebellion from within and stepped into the void of power without extended wars.

Over the past few centuries, the Great Wall has served as a source of building materials for local farms and villages. Aerial photos show that in sections, only the top battlements show -- the center of the wall has filled with sand and silt. The same brutal isolated conditions which made the Great Wall a triumph of engineering and determined planning make restoration problematic and slow.

Symptoms of dengue fever

0 comments

Dengue fever usually starts suddenly with a high fever, rash, severe headache, pain behind the eyes, and muscle and joint pain. The severity of the joint pain has given dengue the name break bone fever. Nausea, vomiting, and loss of appetite are common. A rash usually appears 3 to 4 days after the start of the fever. The illness can last up to 10 days, but complete recovery can take as long as a month. Older children and adults are usually sicker than young children.

Most dengue infections result in relatively mild illness, but some can progress to dengue hemorrhagic fever. With dengue hemorrhagic fever, the blood vessels start to leak and cause bleeding from the nose, mouth, and gums. Bruising can be a sign of bleeding inside the body. Without prompt treatment, the blood vessels can collapse, causing shock. Dengue hemorrhagic fever is fatal in about 5 percent of cases, mostly among children and young adults.

The time between the bite of a mosquito carrying dengue virus and the start of symptoms averages 4 to 6 days, with a range of 3 to 14 days. An infected person cannot spread the infection to other persons but can be a source of dengue virus for mosquitoes for about 6 days.

Great Pyramid of Giza

0 comments
It is located at the city of Giza, a necropolis of ancient Memphis, and today part of Greater Cairo, Egypt.

Contrary to the common belief, only the Great Pyramid of Khufu (Cheops), not all three Great Pyramids, is on top of the list of Wonders. The monument was built by the Egyptian pharaoh Khufu of the Fourth Dynasty around the year 2560 BC to serve as a tomb when he dies. The tradition of pyramid building started in Ancient Egypt as a sophistication of the idea of a mastaba or "platform" covering the royal tomb. Later, several stacked mastabas were used. Early pyramids, such as the Step Pyramid of King Zoser (Djoser) at Saqqara by the famous Egyptian architect, Imhotep, illustrate this connection.

The great pyramid is believed to have been built over a 20 year period. The site was first prepared, and blocks of stone were transported and placed. An outer casing (which disappeared over the years) was then used to smooth the surface. Although it is not known how the blocks were put in place, several theories have been proposed. One theory involves the construction of a straight or spiral ramp that was raised as the construction proceeded. This ramp, coated with mud and water, eased the displacement of the blocks which were pushed (or pulled) into place. A second theory suggests that the blocks were placed using long levers with a short angled foot.

Throughout their history, the pyramids of Giza have stimulated human imagination. They were referred to as "The Granaries of Joseph" and "The Mountains of Pharaoh". When Napoleon invaded Egypt in 1798, his pride was expressed through his famous quote: "Soldats! Du haut de ces Pyramides, 40 siècles nous contemplent". (Soldiers! From the top of these Pyramids, 40 centuries are looking at us)

Today, the Great Pyramid is enclosed, together with the other pyramids and the Sphinx, in the touristic region of the Giza Plateau. Also in the area is the museum housing the mysterious Sun Boat, only discovered in 1954 near the south side of the pyramid. The boat is believed to have been used to carry the body of Khufu in his last journey on earth before being buried inside the pyramid. It may also serve him as a means of transportation in his afterlife journey according to Ancient Egyptian beliefs.

Nanny

0 comments
A nanny is defined as a child's nurse. The traditional nanny was a servant in a large household and reported directly to the lady of the house. Nannies were always female and this remained the case through the 20th Century. This role currently stands firmly as a sector of early childhood education.The nanny in a great house ran her own tiny domain, supported by at least one nursery maid. Because of their role in child care, they were somewhat more indulged than junior servants. Nannies may have remained in the employ of the same aristocratic family for years, looking after successive generations of children.

Today, although many families employ part-time babysitters, fulltime nannies in the classic sense can only be afforded by upper-middle to upper class families.Typically, girls and women in the 20 to 30 age bracket take up employment as nannies. Some are younger. In many poorer countries, many teenage girls also work as nannies. Nannies typically earn low salaries. Sometimes the employer requires their nanny/nannies to wear a uniform. This happened often earlier during the 20th century, but since the 1990s many nannies instead can wear clothes that are comfortable for their work. A nanny uniform can include a dress or blouse and skirt.

Philippines

0 comments
The Philippines, officially the Republic of the Philippines, is an island nation located in the Malay archipelago in Southeast Asia, with Manila as its capital. It comprises 7,107 islands called the Philippine Archipelago, with a total land area of approximately 300,000 square kilometers or 116,000 square miles.
The people of the Philippines are called Filipinos. Most Filipinos are descended from the indigenous Austronesian-speaking peoples, but there are also some Filipinos of mixed descent, known as mestizos, through intermarriage with the Chinese, Spanish or other nationalities.
The country was named "Las Islas Filipinas" by Ruy López de Villalobos after King Philip II of Spain. A Spanish colonial rule through Mexico began in 1565 and lasted for about three centuries until the Philippine Revolution of 1896. The United States gained possession of the Philippines after the Spanish-American War in 1898 and ruled the country for about five decades. Philippine culture has many affinities with the West. Roman Catholicism is the predominant religion, and English is an official language, along with Tagalog.
The Philippines is a significant source of migrant workers; there are over 9 million overseas Filipinos and their remittances exceed $12 billion a year, an amount that forms a significant portion of the Philippines' gross national product. Moreover, the country exports more than one million of its nationals abroad annually through its overseas employment program. Due to this, the Filipino diaspora has become the third largest among overseas ethnicities.

Organism

0 comments


In biology and ecology, an organism (in Greek organon = instrument) is a living complex adaptive system of organs that influence each other in such a way that they function in some way as a stable whole.
An organism is in a non-equilibrium thermodynamic state, maintaining a homeostatic internal environment, and a continuous input of energy is required to maintain this state.
The origin of life and the relationships between its major lineages are controversial. Two main grades may be distinguished, the prokaryotes and eukaryotes. The prokaryotes are generally considered to represent two separate domains, called the Bacteria and Archaea, which are not closer to one another than to the eukaryotes. The gap between prokaryotes and eukaryotes is widely considered a major missing link in evolutionary history. Two eukaryotic organelles, namely mitochondria and chloroplasts, are generally considered to be derived from endosymbiotic bacteria.
The phrase complex organism describes any organism with more than one cell.

Xerxes:

Xerxes:

When scouts initially informed Xerxes of the size of the Greek force and of the Spartans who were performing preparations which included naked calisthenics and combing their hair, Xerxes found the reports laughable. He projected the compel to part at any moment and waited four days for the Greek force to retreat and this was due to the not understanding the ritual significance of the Spartan preparations as the actions of men with the resolution to fight to the end. On the fifth day he ordered his troop to get in to the pass. Finally the Greeks deployed themselves in a phalanx, a wall of overlapping shields and layered spear points, spanning the entire width of the pass.
