Mars exploration Orbiter Status

The High Resolution Imaging Science Experiment (HiRISE) camera on the orbiter has now taken more than 3,000 images of Mars, resolving features as small as a desk in targeted areas covering thousands of square miles of the Martian surface. Already, this is the largest Mars data set ever acquired by a single experiment. The camera is one of six instruments on the orbiter.

During the first three months after the orbiter's primary science phase began in November, researchers saw an increase in noise and pixel dropouts in data from seven of the camera's 14 detectors. The effects on image quality were small in all but two detectors, but the trend raised concerns noted in a Feb. 7 news release.

Tests have yielded an explanation for the earlier pattern, and the camera's performance record shows the noise stopped getting worse after about three to four months of the science phase. Alfred McEwen of the University of Arizona, Tucson, principal investigator for the camera, said, "I'm happy to report that there has been no detectable degradation over the past five months."

A team at Ball Aerospace & Technologies Corp., Boulder, Colo., designer and builder of the instrument, has used an engineering model of the camera's focal-plane system to successfully duplicate the problem. This has helped in understanding causes and in testing a procedure for warming the focal-plane electronics prior to each image. One cause is that an electrical interface lacked extra capability beyond minimum requirements. Another cause is an unexpected change in performance of another electronic component over the course of the first thousand or so large images. With pre-warming, the camera acquires good data from all detectors, though minor noise remains an issue in data from one of two channels of one detector collecting infrared imagery.

Google to offer content from European news agencies

Content from eight of the national news agencies that own the European Pressphoto Agency (EPA) is to be made available on the Internet via Google News, under a new accord announced here.

Users of Google News will be able to access both text and photos from the participating agencies, EPA and Google said in a joint statement Tuesday.

"This new approach not only enhances the experience for users, it also gives proper recognition to journalists and publishers who work hard to break the news," Josh Cohen, Google News' business product manager, said of the initiative.

Jörg Schierenbeck, EPA's managing director, hailed the accord as "good for all".

"EPA, the participating agencies and Google will benefit from the monetisation of our original articles and photos hosted by Google, and users will benefit from the user-friendly approach to this type of display of news agency content," he said.

"Previously, Google News would often display multiple copies of the same news agency articles and photos, with separate links to various sites," Google's Cohen said. "Thanks to the agreement with EPA, Google News will now be able to link directly to the original article, on a page hosted by Google."

The EPA stories will also include links to other websites where the items appear.

"The importance of this agreement is that the news agencies are recognised for the original content they create, and can generate new revenue through the advertising revenue share split with Google for all hosted articles on Google News," according to the chairman of EPA's supervisory board, Walter Grolimund.

Frankfurt-based EPA- is a consortium of 11 European news agencies, including Spain's Efe, which is the entity's second-biggest shareholder.

The consortium distributes more than 1,000 photos per day to hundreds of media outlets worldwide.

Google, headquartered in Mountain View, California, is the leading search engine the Internet.

How to Defrost the microwave ovan

* Remove food from packaging before defrosting. Do not use foam trays and plastic wraps because they are not heat stable at high temperatures. Melting or warping may cause harmful chemicals to migrate into food.
* Cook meat, poultry, egg casseroles, and fish immediately after defrosting in the microwave oven because some areas of the frozen food may begin to cook during the defrosting time. Do not hold partially cooked food to use later.
* Cover foods with a lid or a microwave-safe plastic wrap to hold in moisture and provide safe, even heating.
* Heat ready-to-eat foods such as hot dogs, luncheon meats, fully cooked ham, and leftovers until steaming hot.
* After reheating foods in the microwave oven, allow standing time. Then, use a clean food thermometer to check that food has reached 165 °F.

Diagnosis on Cancer

Although the DRE and PSA tests cannot diagnose prostate cancer, they can signal the require for a biopsy to examine the prostate cells and decide whether they are cancerous. In some men, changes in urinary or sexual function lead to a full evaluation by the doctor, and, if prostate cancer is assumed, a biopsy will be performed.

The Biopsy
During a biopsy, needles are inserted into the prostate to take small samples of tissue, often under the guidance of ultrasound imaging. The biopsy procedure may cause some discomfort or pain, but the procedure is short, and can usually be performed without an overnight hospital stay.

Gleason Grading and Gleason Scores
Under normal conditions, prostate cells, just like all other cells in the body, are constantly reproducing and dying, and each new prostate cell has the same shape and facade as all of the other prostate cells. But cancer cells look different, and the degree to which they look different from normal cells is what determines the cancer grade. "Low-grade" tumor cells tend to look very similar to normal cells, whereas "high-grade" tumor cells have mutated so much that they often barely resemble the normal cells.

The Gleason grading system accounts for the five distinct patterns that prostate tumor cells tend to go during as they change from normal cells. The scale runs from 1 to 5, where 1 represents cells that are very nearly normal, and 5 represents cells that don’t look much like prostate cells at all.

After examining the cells under a microscope, the pathologist looking at the biopsy sample assigns one Gleason grade to the most common pattern, and a second Gleason grade to the next most common pattern. The two grades are added, and the Gleason score, or sum, is determined.

Generally speaking, the Gleason score tends to predict the assertiveness of the disease and how it will behave. The higher the Gleason score, the less the cells behave like normal cells, and the more aggressive the tumor tends to be.

Staging the Disease
Staging determines the extent of prostate cancer. Localized prostate cancer means that the cancer is confined within the prostate. Locally advanced prostate cancer means that most of the cancer is confined within the prostate, but some has started to escape to the immediate surrounding tissues. In metastatic disease, the prostate cancer is growing outside the prostate and its immediate environs, possibly to more distant organs.

A number of tests can be used to help determine the stage of disease. For example, cancers growing outside of the prostate can often be detected through traditional imaging studies, such as CT scans, MRIs, or x-rays, or through more specialized imaging tests such as bone scans. Note that because these tests cannot detect very small groups of cancer cells, results of these tests cannot be used alone to determine the stage of the disease, to guide treatment options, or to predict outcomes.

Metastatic disease can also be detected through imaging studies, and often can be detected in the lymph nodes. Cancers that spread to more distant organs tend to travel through the lymph system, a circulatory system similar to the blood surgery, lymph nodes will be removed and examined for the presence of cancer cells.

Knowing the stage of disease can help to determine how aggressively the disease needs to be treated, and how likely it is to be eradicated by the available treatment options.

The Kindle Swindle?

BEING president of too many well-meaning organizations put my father into an early grave. The lesson in this was not lost on me. But now I am president of the Authors Guild, whose mission is to sustain book-writing as a viable occupation. This borders on quixotic, given all the new ways of not getting paid that new technology affords authors. A case in point: Amazon’s Kindle 2, which was released yesterday.

The Kindle 2 is a portable, wireless, paperback-size device onto which people can download a virtual library of digitalized titles. Amazon sells these downloads, and where the books are under copyright, it pays royalties to the authors and publishers.

Serves readers, pays writers: so far, so good. But there’s another thing about Kindle 2 — its heavily marketed text-to-speech function. Kindle 2 can read books aloud. And Kindle 2 is not paying anyone for audio rights.

True, you can already get software that will read aloud whatever is on your computer. But Kindle 2 is being sold specifically as a new, improved, multimedia version of books — every title is an e-book and an audio book rolled into one. And whereas e-books have yet to win mainstream enthusiasm, audio books are a billion-dollar market, and growing. Audio rights are not generally packaged with e-book rights. They are more valuable than e-book rights. Income from audio books helps not inconsiderably to keep authors, and publishers, afloat.

You may be thinking that no automated read-aloud function can compete with the dulcet resonance of Jim Dale reading “Harry Potter” or of authors, ahem, reading themselves. But the voices of Kindle 2 are quite listenable. There’s even a male version and a female version. (A book by, say, Norman Mailer on Kindle 2 might do a brisk business among people wondering how his prose would sound in measured feminine tones.)

And that sort of technology is improving all the time. I.B.M. has patented a computerized voice that is said to be almost indistinguishable from human ones. This voice is programmed to include “ums,” “ers” and sighs, to cough for attention, even to “shhh” when interrupted. According to Andy Aaron, of I.B.M.’s Thomas J. Watson research group speech team: “These sounds can be incredibly subtle, even unnoticeable, but have a profound psychological effect. It can be extremely reassuring to have a more attentive-sounding voice.”

When I read that quotation, it hit me: Hey, I know Andy Aaron. Years ago, he said he was working on some sort of voice simulation, and asked to work my Southern accent into the mix. I don’t remember whether we got around to that or not, and this new I.B.M. software is designed, at any rate, not for audio books but for computer help lines. So no part of my voice is competing with my own audio books yet. But people who want to keep on doing creative things for a living must be duly vigilant about any new means of transmitting their work.

What the guild is asserting is that authors have a right to a fair share of the value that audio adds to Kindle 2’s version of books. For this, the guild is being assailed. On the National Federation of the Blind’s Web site, the guild is accused of arguing that it is illegal for blind people to use “readers, either human or machine, to access books that are not available in alternative formats like Braille or audio.”

In fact, publishers, authors and American copyright laws have long provided for free audio availability to the blind and the guild is all for technologies that expand that availability. (The federation, though, points out that blind readers can’t independently use the Kindle 2’s visual, on-screen controls.) But that doesn’t mean Amazon should be able, without copyright-holders’ participation, to pass that service on to everyone.

The guild is also accused of wanting to profiteer off family bedtime rituals. A lawyer at the Electronic Frontier Foundation sarcastically warned that “parents everywhere should be on the lookout for legal papers haling them into court for reading to their kids.”

For the record: no, the Authors Guild does not expect royalties from anybody doing non-commercial performances of “Goodnight Moon.” If parents want to send their children off to bed with the voice of Kindle 2, however, it’s another matter.

Roy Blount Jr. is the author, most recently, of “Alphabet Juice.”

Internet

The Internet is a worldwide system of interconnected computer networks that interchange data by small package switching using the standardized Internet Protocol Suite (TCP/IP). It is a "network of networks" that consists of millions of private and public, academic, business, and government networks of restricted to global scope that are linked by copper wires, fiber-optic cables, wireless connections, and additional technologies.

The Internet carries a variety of information resources and services, such as electronic mail, online chat, file transfer and file sharing, online gaming, and the inter-linked hypertext documents and other resources of the World Wide Web (WWW).

What is pointing device?

A pointing device is an input interface (particularly a human interface device) that allows a user to input spatial (i.e., continuous and multi-dimensional) data to a computer. CAD systems and graphical user interfaces (GUI) let the user to control and give data to the computer using physical gestures — point, click, and drag — for instance by moving a hand-held mouse across the surface of the physical desktop and activating switches on the mouse. Movements of the pointing device are echoed on the screen by movements of the pointer (or cursor) and added visual changes.

While the nearly all common pointing device by far is the mouse, a lot of more devices have been developed. But, mouse is normally used as a metaphor for devices that move the cursor.

What is called The Sandbox in search engine?

It's thought that Google has implemented a time penalty for new links and web sites before completely marking the index, based on the presumption that 100,000-page websites can't be created in overnight. Certain web sites, or links to them, are "sandboxed" for a period of time previous to they are given full rank in the index. Speculation is that only a set of competitive keywords (the ones that are manipulated the most) are sandboxed. A drifting legend in the search engine world, the way of life of the Sandbox has been debated, and is yet to be long-established by Google.

Instant messaging

Instant messaging (IM) and chat are technologies that make the possibility of real-time text-based communication between two or more participants over the internet or some form of internal network/intranet. It is important to understand that what separates chat and instant messaging from technologies such as e-mail is the apparent synchronicity of the communication by the user - Chat happens in real-time previous to your eyes. Some systems allow the sending of messages to people not at present logged on (offline messages), thus removing much of the difference between Instant Messaging and e-mail.

As many services have additional features such as: the instant receipt of acknowledgment or reply, group chatting, conference services (including voice and video), conversation logging and file transfer, those functions are further than the scope of this article.

IM allows effectual and efficient communication, featuring immediate receiving of acknowledgment or reply. In certain cases Instant Messaging involves extra features, which make it still more popular, i.e. to observe the other party, e.g. by using web-cams, or to talk directly for free over the Internet.

SEO tunnel vision can carry various symptoms, and symptoms may differ from person to person. On the other hand, there are some symptoms that occur in the greater part of cases:

1. You can list your website's correct search engine position in Google and Yahoo, however you're not definite how many web-driven sales you've had this month.

2. You give keyword density a higher precedence than readability.

3. You didn't see your sales falling last quarter for the reason that you were too busy tweaking your page titles.

4. You act in response to customer complaints by saying things like, "Jeez, what's wrong with his algorithm?"

5. You think about your best customer to be a math-loving spider named "bot."

What is the SEO Tunnel Vision mean by its word?

The SEO Tunnel Vision condition affects thousands of search engine marketers, webmasters and business owners. Luckily, it's simple to treat. SEO tunnel vision occurs when a person concentrates so much of their interest on search engine ranking that they lose website of the bigger picture of website achievement.

Slowly, over an age of weeks or months, victims of SEO tunnel vision not remember that search engine visibility is only a beginning, not an end. In other words, they start to take care of search engine ranking as the definitive form of online success.

If left untreated, SEO tunnel vision can lead to a drop in website conversions, a cut in overall sales, and many missed opportunities. This situation is as well referred to as website blindness, hyper-search syndrome, spider vision and Google-itis.

Scratchpad RAM

Scratchpad memory (SPM), as well known as scratchpad, scatchpad RAM or neighboring store in computer terminology, is a high-speed inner memory used for temporary storage of calculations, data, and other work in progress. In situation to a microprocessor ("CPU"), scratchpad refers to a particular high-speed memory circuit used to hold small items of data for quick retrieval.

It can be considered as alike to an L1 cache in that it is the memory subsequently closest to the ALU's after the internal registers, with explicit instructions to move data from and to major memory, often by means of DMA-based data transfer.

Normally, a cache is used to temporarily store copies of data that resides on slower major memory. On the other hand, the CPU can use scratchpad RAM for any purpose, like storing instructions or intermediate values.

Abstract art
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 nonfigurative 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 easy 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' absolute intrinsic qualities rather than its external appearance. The more precise terms, "non-figurative art," "non-objective art," and "non-representational art" keep away from any possible ambiguity.

Camera
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.

Bluetooth

Bluetooth is an industrial requirement for wireless personal area networks (PANs). Bluetooth provides a way to connect and swap information between devices such as mobile phones, laptops, PCs, printers, digital cameras, and video game consoles over a secure, globally unlicensed short-range radio frequency. The Bluetooth specifications are licensed and developed by the Bluetooth Special Interest Group.

Bluetooth is a radio standard and communications protocol mostly designed for low power consumption, with a short range based on low-cost transceiver microchips in each device. The devices use a radio communications system, so they do not have to be in line of view of each other, and can even be in other rooms, as long as the conservative transmission is powerful enough.

Sandstones

Sandstone is an arenaceous sedimentary rock composed mostly of feldspar and quartz and varies in colour (in a similar way to sand), through grey, yellow, red, and white. Since sandstones often form extremely visible cliffs and other rock formations, certain colors of sandstone may be strongly identified with certain regions. For instance, much of the North American West is familiar for its red sandstones.

Trailers

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.

Scientific Methods

The scientific method seeks to explain the complexities of nature in a replicable way, and to use these explanations to construct useful predictions. It provides an objective method to find solutions to problems in a number of scientific and technological fields. Often scientists have a predilection for one outcome over another, and scientists are conscientious that it is vital that this preference does not bias their interpretation. A strict following of the scientific method attempts to minimize the pressure of a scientist's bias on the outcome of an experiment. This can be achieved by correct experimental design, and a thorough peer assessment of the experimental results as well as conclusions of a study.

Scientists use models to refer to a explanation or depiction of something, specifically one which can be used to construct predictions that can be tested by experiment or observation. A hypothesis is a disputation that has been neither well supported nor yet ruled out by experiment. A theory, in the context of science, is a logically self-consistent model or framework for recitation the behavior of certain natural phenomena. A theory typically describes the behavior of much broader sets of phenomena than a hypothesis — commonly, a large number of hypotheses may be logically bound together by a single theory. A physical law or law of nature is a scientific generalization based on a adequately large number of empirical observations that it is taken as fully verified.

Railway

A railroad or railway is a guided means of land transport, designed to be used by trains, for transporting both passengers and goods. It consists of two parallel rails, usually made of steel, and wooden or concrete sleepers or ties that hold the rails accurately at the proper distance from each other. Rail transport is one of the most energy well-organized means of mechanised land transport known. The rails offer very smooth and hard surfaces on which the wheels of the train may roll with a minimum of friction. This is added comfortable and saves energy. Trains also have a tiny frontal area in relation to the load they are carrying, which cuts down on air resistance and thus energy usage. In all, under the right situation, a train needs 50-70% less energy to transport a given tonnage of freight (or given number of passengers), than by road.

Pollutants in water

Pollutants in water consist of a huge spectrum of chemicals, pathogens, and physical chemistry or sensory changes.Various chemical substances are toxic. Pathogens can actually create waterborne diseases in either human or animal hosts. Alteration of water’s physical chemistry contains acidity, conductivity, temperature, and eutrophication. Eutrophication is the fertilization of surface water by nutrients that were before scarce. Even a lot of the municipal water supplies in developed countries can present health risks.

Operating System

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

Nanotechnology

Nanotechnology is a pasture of applied science and technology covering a wide range of topics. The main unifying premise is the control of matter on a scale smaller than 1 micrometer, normally between 1-100 nanometers, as well as the manufacture of devices on this same length scale. It is a highly multidisciplinary field, drawing from fields such as colloidal science, device physics, and supramolecular chemistry. Much hypothesis exists as to what new science and technology might result from these lines of research. Some view nanotechnology as a marketing term that describes pre-existing lines of research applied to the sub-micron size scale.

In spite of the apparent ease of this definition, nanotechnology actually encompasses diverse lines of inquiry. Nanotechnology cuts across many disciplines, together with colloidal science, chemistry, applied physics, materials science, and even mechanical and electrical engineering. It could variously be seen as an extension of existing sciences into the nanoscale, or as a recasting of existing sciences using a newer, more recent term. Two major approaches are used in nanotechnology: one is a "bottom-up" approach where materials and devices are built from molecular components which gather themselves chemically using principles of molecular gratitude; the other being a "top-down" approach where nano-objects are constructed from larger entities without atomic-level control.

Information Technology

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.

Health

Health is the altitude of functional and/or metabolic effectiveness of an organism at both the micro(cellular) and macro(social) level. In the medical field, health is commonly defined as an organism's capability to efficiently respond to challenges (stressors) and effectively restore and sustain a "state of balance," known as homeostasis.

Another widely conventional definition of health is that of the World Health Organization (WHO), which states that "health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity". In more current years, this statement has been modified to include the ability to lead a "socially and economically industrious life." The WHO definition is not without criticism, as some argue that health cannot be defined as a state at all, but must be seen as a process of unremitting adjustment to the varying demands of living and of the changing meanings we give to life. The WHO definition is therefore considered by many as an idealistic goal rather than a realistic proposition.

An increasing measure of the health of populations is tallness, which is strongly synchronized by nutrition and health care, among other standard of living and quality of life matters. The study of human growth, its regulators and its implications is known as auxology.

Geography

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.

Fresh skin-care tips

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.

Coin

A coin is normally a piece of hard material, generally metal, usually in the shape of a disc, and most often issued by a government, to be used as a form of money in transactions of various kinds,from the everyday circulation of the US quarter, to the storage of vast amounts of bullion coins.In modern times coins along with banknotes, coins construct the cash forms of all modern money systems. Coins made for circulation (general monetized use) are usually used for lower-valued units, and banknotes are usually used for the higher values; also, in most money systems, the highest value coin is worth less than the lowest-value note. The face value of circulation coins is usually higher than the gross value of the metal used in manufacturing them.

Exceptions to these rules take place for non-monetized "bullion coins" made of silver or gold (and, rarely, other metals, such as platinum or palladium), intended for collectors or investors in precious metals.Historically, a enormous number of coinage metals (including alloys) and other materials have been used practically, impractically (i.e., rarely), artistically, and experimentally in the construction of coins for both circulation, assortment, and metal investment

Dot matrix printer

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.

Transportation

Transportation is the movement of people and goods from one place to another. The term is derived from the portare ("to carry") and Latin trans ("across") . Industries which have the business of providing equipment, actual transport, transport of people or goods and services used in transport of goods or people make up a huge broad and important segment of most national economies, and are collectively referred to as transport industries.

The field of transport has several aspects: loosely they can be divided into a triad of infrastructure, vehicles, and operations. Infrastructure includes the transport networks (roads, railways, airways, waterways, canals, pipelines, etc.) that are used, as well as the nodes or terminals (such as airports, railway stations, bus stations and seaports). The vehicles generally traverse on the networks, such as automobiles, bicycles, buses, trains, and aircrafts.

Escalator

An escalator is a transport machine for transporting people, consisting of a staircase whose steps move up or down on tracks that stay the surfaces of the individual steps horizontal.A moving walkway, moving sidewalk, revelator, or moderator is a slow conveyor belt that transports people straightly or on a bigotry in a similar manner to an escalator. In both cases, riders can wander or stand. The walkways are often whole in pairs, one for each direction. Modern escalators have metal steps in a stable loop that moves on tracks. Escalators are typically used in pairs with one going up and the other going down.

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.

Automobile

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.

Business

In economic business is the social science of managing people to systematize and maintain collective productivity toward accomplishing particular imaginative and productive goals, usually to make profit.The etymology of "business" refers to the state of being busy, in the circumstance of the individual as well as the community or society. In other words, to be busy is to be doing commercially viable and profitable work.

The term "business" has at least three usages, depending on the scope — the general usage (above), the particular usage to refer to a particular company or corporation, and the comprehensive usage to refer to a particular market sector, such as "the record business," "the computer business," or "the business community" -- the community of suppliers of goods and services.

The singular "business" can be a legally-recognized entity within an economically free society, wherein individuals systematize based on expertise and skill bring about social and technological expansion.

However, the exact definition of business is disputable as is business philosophy; for example, most Marxist use "means of production" as a rough synonym for "business." Socialist advocate either government, public, or worker ownership of most sizable businesses.

Nature

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.

Currency

A currency is a component of exchange, facilitating the transfer of supplies and services. It is a form of money, where money is an capable medium of exchange, and it is also considered by a number of people as a store of value, created through a claim to its central bank assets. A currency zone is a country in which a specific currency is the main medium of exchange. To facilitate trade between currency zones, there are exchange price at which currencies can be exchanged beside each other. Currencies can be classified as also floating currencies or fixed currencies based on their exchange rate regime.

In general usage, currency at times refers to only paper money, as in "coins and currency", but this is confusing. Coins and paper money are both forms of currency.
In most cases, each country has control over the supply and manufacture of its own currency.

CD-ROM

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.

Animals

Animals are a main set of organisms, classified as the empire Metazoa. In general they are multicellular, receptive to their surroundings, and provide for by consuming other organisms or parts of them. Their body plan becomes fixed when they develop, generally early on in their growth as embryos, though some feel a process of metamorphosis later on.

The word "animal" comes from the Latin word animal, of which Metazoa is the plural, and is resulting from anima, sense vital breath or soul. In each day colloquial usage, the word regularly refers to non-human animals. The biological meaning of the word refers to all members of the empire Animalia. Therefore, as the word "animal" is used in a biological circumstance, humans are included.

Formation of a waterfall:

Typically, a river flows over a large step in the rocks which may have been formed by a fault line. Over a period of years, the boundaries of this shelf will gradually break away and the waterfall will steadily retreat upstream, creating a gorge of depression. Often, the rock layer just below the more resistant shelf will be of a softer type, meaning undercutting, due to splashback, will occur here to form a thin cave-like formation known as a rock shelter under and behind the waterfall. Finally, the outcropping, more resistant cap rock will fall down under pressure to add blocks of rock to the base of the waterfall. These blocks of rock are then broken down into smaller boulders by attrition as they crash with each other, and they also erode the base of the waterfall by abrasion, creating a deep plunge pool.

Lavender flowers give up abundant nectar which yields a high eminence honey for beekeepers. Lavender monofloral honey is formed primarily in the nations around the Mediterranean, and marketed worldwide as a finest product. Lavender flowers can be candied and are used as cake embellishment. Lavender is also used as a herb, either alone or as an ingredient of herbes de Provence. Lavender is also used to flavour sugar, the product being called "lavender sugar", and the flowers are sometimes sold in a blend with black tea, as "lavender tea".

A statue of just a head and shoulders is a bust not to be perplexed with the anatomical part of the female body referring to the chest or the part of a dress. Many statues are built on payment to honor a historical event, or the life of an powerful person. Many statues are intended as public art, exhibited outdoors or in public buildings for the edification of passers-by, with a larger size than normal words could ever have for the common man.

Research in Psychology:

Research in psychology is conducted in broad agreement with the standards of the scientific method, encircling both qualitative ethological and quantitative statistical modalities to generate and evaluate explanatory hypotheses with regard to psychological phenomena. Where look into ethics and the state of development in a given research domain permits, investigation may be pursued by experimental protocols.

Psychology tends to be eclectic, drawing on scientific knowledge from other fields to help explain and understand psychological phenomena. Qualitative psychological research utilizes a broad spectrum of observational methods, including action research, ethnography, exploratory statistics, structured interviews, and participant observation, to facilitate the gathering of rich information unattainable by classical experimentation. Research in humanistic psychology is more typically pursued by ethnographic, historical, and historiographic methods.

Greek temple

The Greeks began to build massive temples in the first half of the 8th century BC. The temples of Hera at Samos and of Poseidon at Isthmia were among the first erected. Greek temples differed from their Roman counterparts in that the colonnade shaped a peristyle around the whole structure, rather than merely a porch at the front; and also in that the Greek temple was not raised above ground level on a high podium.

As the Greeks became more adept at massive building, regional styles of architecture solidified into what are now the classical orders of architecture: Doric, Ionic and Corinthian. The Parthenon, one of the most famous Greek temples, was devoted to Athena, goddess of wisdom. Festivals were held in and around it every year. The Parthenon powerfully influenced Roman architecture. After the Romans conquered Greece, many tourists from the victorious country came to view the temples of Greece. Among them was the Parthenon, which rapidly became one of the most popular tourist sites in Greece. Unlike modern places of worship, Greek temples were not intended for group worship, but more as a dedication to a god or goddess, explaining why the sculpture on temples was always right at the top and hard to see - it was built for the pleasure of its deity and not for people.

Cloud

A cloud is a visible mass of condensed droplets or frozen crystals suspended in the atmosphere above the surface of the Earth or another planetary body. The branch of meteorology in which clouds are studied is nephology.

On Earth, the condensing substance is water vapor, which forms small droplets of water or ice crystals, typically 0.01 mm in diameter. When surrounded with billions of other droplets or crystals, they are visible as clouds. Dense deep clouds exhibit a high reflectance throughout the visible range of wavelengths: they thus appear white, at least from the top. Cloud droplets tend to scatter light very efficiently, so that the intensity of the solar radiation decreases with depth into the cloud, hence the grey or even sometimes dark appearance of the clouds at their base. Thin clouds may appear to have acquired the color of their environment or background, and clouds illuminated by non-white light, such as during sunrise or sunset, may be colored accordingly. In the near-infrared range, however, clouds would appear very dark because the water that constitutes the cloud droplets strongly absorb solar radiation at these wavelengths.

Sri Lankan Ayurvedic tradition

Sri Lanka, with an archeological history dating back to at least 30,000 B.C., has its own indigenous scheme of medicine. This system has been practised for many centuries in the island nation. The Sri Lankan Ayurvedic tradition is a mixture of the Ayurveda systems of North India, the Siddha system of South India, Unani medicine from the Arabs, and most importantly, the Desheeya Chikitsa, which is the indigenous medicine of Sri Lanka.

The word "Ayurveda" translates into English as the "science of life" . Considered to be the oldest healing science in the world, this ancient medicine is practiced extensively in Sri Lanka and India. Passed down through time, this system focuses on the connection between the body and the mind. Using natural cures, Ayurveda aims to maintain the body in a balanced state of health.Sri Lanka developed its own Ayurvedic system based on a series of prescriptions handed down from generation to generation over a period of 3,000 years. The ancient kings, who were also prominent physicians, sustained its survival and longevity. King Buddhadasa , the most influential of these physicians, wrote the Sarartha Sangrahaya, a comprehensive manuscript which Sri Lankan physicians still use today for reference.

History of Hanging Gardens

It is Located on the east bank of the River Euphrates, about 50 km south of Baghdad, Iraq.

The Babylonian kingdom flourished under the rule of the famous King, Hammurabi (1792-1750 BC). It was not until the reign of Naboplashar (625-605 BC) of the Neo-Babylonian dynasty that the Mesopotamian civilization reached its ultimate glory. His son, Nebuchadnezzar II (604-562 BC) is credited for building the legendary Hanging Gardens. It is said that the Gardens were built by Nebuchadnezzar to please his wife or concubine who had been "brought up in Media and had a passion for mountain surroundings".

While the most descriptive accounts of the Gardens come from Greek historians such as Berossus and Diodorus Siculus, Babylonian records stay silent on the matter. Tablets from the time of Nebuchadnezzar do not have a single reference to the Hanging Gardens, although descriptions of his palace, the city of Babylon, and the walls are found. Even the historians who give detailed descriptions of the Hanging Gardens never saw them. Modern historians argue that when Alexander's soldiers reached the fertile land of Mesopotamia and saw Babylon, they were impressed. When they later returned to their rugged homeland, they had stories to tell about the amazing gardens and palm trees at Mesopotamia... About the palace of Nebuchadnezzar. About the Tower of Babel and the ziggurats. And it was the imagination of poets and ancient historians that blended all these elements together to produce one of the World Wonders.

The Mausoleum at Halicarnassus

Similar to the Great Pyramid, we are now visiting the burial place of an ancient king. Yet the Mausoleum is different - so different from the Pyramid that it earned its reputation - and a spot within the list - for other reasons. Geographically, it is closer to the Temple of Artemis... And it was the beauty of the tomb rather than its size that fascinated its visitors for years. In the city of Bodrum on the Aegean Sea, in south-west Turkey.

The structure was rectangular in plan, with base dimensions of about 40 m (120 ft) by 30 m (100 ft). Overlying the foundation was a stepped podium which sides were decorated with statues. The burial chamber and the sarcophagus of white alabaster decorated with gold were located on the podium and surrounded by Ionic columns. The colonnade supported a pyramid roof which was in turn decorated with statues. A statue of a chariot pulled by four horses adorned the top of the tomb.

Home Decorations

A doll is a model of a human, a humanoid, an animal or a fictional character, usually made of cloth or plastic. Sometimes, intended as keepsakes or collections for older children and adults, it could be made in wood, porcelain, bisque, celluloid or wax.

Reverse Osmosis

Common use for Reverse osmosis is in purifying water where it produces water, which is in demand at all, places. One of the finest filtration under Reverse Osmosis is Hyper Filtration, where the removals of particles are as small as ions. In this Process, water gets purified and the various salts and other impurities are removed to improve the Properties of fluid, its taste as well as color.

Reverse osmosis occurs when the water is moved across the membrane against the concentration gradient, from lower concentration to higher concentration. It thus purifies water by ejecting out fluids, inorganic chemicals such as nitrates, calcium, and magnesium, other ions and contaminants.

It uses a semi-permeable membrane, allowing the fluid that is being purified to pass through it. Most of the reverse osmosis technology procedures undergoes a cross flow Process to allow the membrane to clean itself periodically. As some of the fluid gets rested in downstream, continuous cross-flow process helps or sweeps out the rejected species away from the membrane.

Taj Mahal

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.

The Great Barrier Reef

Spanning more than 2000 km along the northeastern coast of Australia, the Great Barrier Reef is home to thousands of species of plants and animals. The Reef which runs parallel to the Queensland coast has been designated by the Australian Government as a Marine Park.

Few can imagine the biological diversity of the reef. One probably has to realize first that the 2000 km long reef runs predominantly in the North-South direction, therefore spanning a wide range of climates. Rain forests and mountains are predominant in the northern islands, while the southern islands are composed mainly of Coral Cay.

Apart from its environmental value, the area offers visitors a variety of activities including scuba diving, snorkeling, water sports, and bird watching.

Symptoms of dengue fever

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

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.

Reduce the risk of acquiring dengue

There is no vaccine for preventing dengue. The best preventive measure for residents living in areas infested with Aedes aegypti is to eliminate the places where the mosquito lays her eggs, primarily artificial containers that hold water.

Items that collect rainwater or are used to store water (for example, plastic containers, 55-gallon drums, buckets, or used automobile tires) should be covered or properly discarded. Pet and animal watering containers and vases with fresh flowers should be emptied and scoured at least once a week. This will eliminate the mosquito eggs and larvae and reduce the number of mosquitoes present in these areas.

For travelers to areas with dengue, a well as people living in areas with dengue, the risk of being bitten by mosquitoes indoors is reduced by utilization of air conditioning or windows and doors that are screened. Proper application of mosquito repellents containing 20% to 30% DEET as the active ingredient on exposed skin and clothing decreases the risk of being bitten by mosquitoes. The risk of dengue infection for international travelers appears to be small, unless an epidemic is in progress.

Sound recording and reproduction

Sound recording and reproduction is the electrical or mechanical re-creation and/or amplification of sound, often as music. This involves the use of audio equipment such as microphones, recording devices and loudspeakers. From early beginnings with the invention of the phonograph using purely mechanical techniques, the field has advanced with the invention of electrical recording, the mass production of the 78 record, the magnetic wire recorder followed by the tape recorder, the vinyl LP record. The invention of the compact cassette in the 1960s, followed by Sony's Walkman, gave a major boost to the mass distribution of music recordings, and the invention of digital recording and the compact disc in 1983 brought massive improvements in ruggedness and quality. The most recent developments have been in digital audio players like the Apple iPod. New technologies such as Super Audio CD and DVD-A continue to set very hi-fi digital standards.

Cocaine is a crystalline tropane alkaloid that is obtained from the leaves of the coca plant. It is a stimulant of the central nervous system and an appetite suppressant, creating what has been described as a euphoric sense of happiness and increased energy. Though most often used recreationally for this effect, cocaine is also a topical anesthetic used in eye, throat, and nose surgery. Cocaine can be psychologically addictive, and its possession, cultivation, and distribution is illegal for non-medicinal and non-government sanctioned purposes in virtually all parts of the world. The name comes from the name of the coca plant plus the alkaloid suffix -ine.
The stimulating qualities of the coca leaf were known to the ancient peoples of Peru and other Pre-Columbian South American societies. In modern Western countries, cocaine has been a feature of the counterculture for well-over a century; there is a long-list of prominent intellectuals, artists, and musicians who have used the drug -- names ranging from Sir Arthur Conan Doyle and Sigmund Freud to United States President Ulysses S. Grant. For many decades cocaine was a key ingredient in Coca-Cola. Today, although illegal in virtually all countries, cocaine remains popular in a wide variety of social and personal settings.

Football

Football is the name given to a number of different, but related, team sports. The most popular of these worldwide is Association football, which also goes by the name of soccer. The English language word football is also applied to Rugby football Rugby union and Rugby league, North American football Australian rules football, and Gaelic football.

Some of the many different codes of football.While it is widely believed that the word football, or "foot ball", originated in reference to the action of a foot kicking a ball, there is a rival explanation about the foot ball, which has it that football originally referred to a variety of games in medieval Europe, which were played on foot.[1] These games were usually played by peasants, as opposed to the horse-riding sports often played by aristocrats. While there is no conclusive evidence for this explanation, the word football has always implied a variety of games played on foot, not just those that involved kicking a ball. In some cases, the word football has been applied to games which have specifically outlawed throwing balls.
