podcast

A podcast is a digital media file, or a series of such files, that is distributed over the Internet using syndication feeds for playback on portable media players and personal computers. A podcast is a specific type of webcast which, like 'radio', can mean either the content itself or the method by which it is syndicated; the latter is also termed podcasting. The host or author of a podcast is often called a podcaster. The term "podcast" is a portmanteau of the name of Apple's portable music player, the iPod, and broadcast; a "pod" refers to a container of some sort, and "cast" to the idea of broadcasting.

BULLING

Bullying is the intentional tormenting of others through verbal harassment, physical assault, or other more subtle methods of coercion such as manipulation. There is currently no legal definition of bullying.
The effects of bullying can be serious and even fatal. About 85% of bullying victims suffer long term psychological damage and stress related disease later in their lives.
There have been many examples of people dying as a result of bullying. Victims of bullying either commit suicide or are killed by their bullies. There are also cases of death occurring as an indirect result of bullying, such as bullies or other people killed by victims of bullying.


CIBER-BULLING
Cyberbullying occurs in electronic space. According to Canadian educator Bill Belsey, it:
"involves the use of information and communication technologies such as e-mail, cell phone and pager text messages, instant messaging, defamatory personal Web sites, blogs, online games and defamatory online personal polling Web sites, to support deliberate, repeated, and hostile behaviour by an individual or group, that is intended to harm others".Bullies will even create blogs to intimidate victims worldwide.

the collapsing ice sheets to the north.
The Sahara has one of the harshest climates in the world. It has many strong winds that blow from the north-east. Sometimes on the border zones of the north and south, the desert will receive about 25 cm of rain a year. The rainfall happens very rarely, but when it does it is usually torrential when it occurs after long dry periods, which can last for years. Daytime temperatures can be 58 °C.
