TECHNOLOGIES: MOBILE OS ( OPERATING SYSTEMS )

Android 

is an operating system based on the Linux kernel with a user interface based on direct manipulation, designed primarily fortouchscreen mobile devices such as smartphones and tablet computers, using touch inputs, that loosely correspond to real-world actions, like swiping, tapping, pinching, and reverse pinching to manipulate on-screen objects, and a virtual keyboard. Despite being primarily designed for touchscreen input, it also has been used in televisions, games consoles, digital cameras, and other electronics

IOS.

OS (previously iPhone OS) is a mobile operating system developed by Apple Inc. and distributed exclusively for Apple hardware. It is the operating system that powers iPhone, iPad, iPod Touch, and Apple TV.

Originally unveiled in 2007 for the iPhone, it has been extended to support other Apple devices such as the iPod Touch(September 2007), iPad (January 2010), iPad Mini (November 2012) and second-generation Apple TV onward (September 2010). As of October 2013, Apple's App Store contained more than 1 million iOS applications, 500,000 of which were optimized for iPad.

WINDOWS PHONE.

Windows Phone (abbreviated as WP) is a proprietary smartphone operating system developed by Microsoft. It is the successor to Windows Mobile, although it is incompatible with the earlier platform.design language named "Modern" (which was formerly known as "Metro"). Unlike its predecessor, it is primarily aimed at the consumer market rather than the enterprise market. It was first launched in October 2010 with Windows Phone 7.

                               BLACKBERRY 10.

BlackBerry 10 is a proprietary mobile operating system developed by BlackBerry Limited for its BlackBerry line ofsmartphone and tablet handheld devices. Devices running BlackBerry 10 are the Q5, Q10, Z3, Z10, Z30 and the P'9982 smartphones. BlackBerry 10 is based on the QNX operating system, which is popular in industrial computers and used in many car computers,

 which was acquired by BlackBerry in April 2010.

TECHNOLOGIES: INTERNET SAFETY.

Social networking through sites like Facebook, Twitter, and LinkedIn is flourishing like never before, and many of us have now become comfortable with communicating online. These tips will include how to set up a profile, what to consider before you share, what to do when you meet people face to face, and how to practice good netiquette.

Most social networking sites require you to set up a profile to join. Some profiles are simple and may only include a screen name and image, like when you join a website's discussion board.

Technology:EFECTS OF RADIOACTIVE WASTES

Radioactive wastes are wastes that contain radioactive material. Radioactive wastes are usually by-products of nuclear power generation and other applications of nuclear fission or nuclear technology, such as research and medicine. Radioactive waste is hazardous to most forms of life and the environment, and is regulated by government agencies in order to protect human health and the environment.

Radioactivity naturally decays over time, so radioactive waste has to be isolated and confined in appropriate disposal facilities for a sufficient period of time until it no longer poses a hazard. The period of time waste must be stored depends on the type of waste and radioactive isotopes. It can range from a few days for very short-lived isotopes to millions of years for spent nuclear fuel. Current major approaches to managing radioactive waste have been segregation and storage for short-lived waste, near-surface disposal for low and some intermediate level waste, and deep burial or partitioning / transmutationfor the high-level waste.

A summary of the amounts of radioactive waste and management approaches for most developed countries are presented and reviewed periodically as part of the International Atomic Energy Agency (IAEA) Joint Convention on the Safety of Spent Fuel Management and on the Safety of Radioactive Waste Management.

FOOTBALL: FIFA WORLD CUP. BRASIL 2014.

The FIFA World Cup, often simply the World Cup, is an international association football competition contested by the senior men's national teams of the members of Fédération Internationale de Football Association (FIFA), the sport's global governing body. The championship has been awarded every four years since the inaugural tournament in 1930, except in 1942 and 1946 when it was not held because of the Second World War. The current champions are Spain, who won the 2010 tournament in South Africa.

The current format of the tournament involves 32 teams competing for the title at venues within the host nation(s) over a period of about a month; this phase is often called the World Cup Finals. A qualification phase, which currently takes place over the preceding three years, is used to determine which teams qualify for the tournament together with the host nation(s).

The 19 World Cup tournaments have been won by eight different national teams. Brazil have won five times, and they are the only team to have played in every tournament. The other World Cup winners are Italy, with four titles; West Germany, with three titles;Argentina and inaugural winners Uruguay, with two titles each; and England, France, and Spain, with one title each.

The World Cup is among the world's most widely viewed sporting events; an estimated 715.1 million people watched the final match of the 2006 FIFA World Cup held in Germany.

The next three World Cups will be hosted by Brazil in 2014, Russia in 2018, and Qatar in 2022.

BIOLOGY: GMO´S (GENETICALY MODIFIED ORGANISM)

A genetically modified organism (GMO) is an organism whose genetic material has been altered using genetic engineering techniques. Organisms that have been genetically modified include micro-organisms such as bacteria and yeast, insects, plants, fish, and mammals. GMOs are the source of genetically modified foods, and are also widely used in scientific research and to produce goods other than food. The term GMO is very close to the technical legal term, 'living modified organism' defined in the Cartagena Protocol on Biosafety, which regulates international trade in living GMOs (specifically, "any living organism that possesses a novel combination of genetic material obtained through the use of modern biotechnology").

This article focuses on what organisms have been genetically engineered, and for what purposes. The article on genetic engineering focuses on the history and methods of genetic engineering, and on applications of genetic engineering and of GMOs. Both articles cover much of the same ground but with different organizations (sorted by organism in this article; sorted by application in the other). There are separate articles ongenetically modified crops, genetically modified food, regulation of the release of genetic modified organisms, and controversies.

GEOGRAPHY: AXIS

In astronomy, axial tilt, known to astronomers as obliquity, is the angle between an object's rotational axisand its orbital axis, or, equivalently, the angle between its equatorial plane and orbital plane. It differs fromorbital inclination. In the Earth, the axis causes in summer 24- hour days and in winter 24-hour nights. Example countries: Sweden, Norway and Finland.
