Videophone calls (also: videocalls, video chat as well as Skype and Skyping in verb form), differ from videoconferencing in that they expect to serve individuals, not groups. However that distinction has become increasingly blurred with technology improvements such as increased bandwidth and sophisticated software clients that can allow for multiple parties on a call. In general everyday usage the term videoconferencing is now frequently used instead of videocall for point-to-point calls between two units. Both videophone calls and videoconferencing are also now commonly referred to as a video link.

Ah, so.. Skype

The House of Representatives, whose members are elected to serve five-year terms, specialises in legislation. Elections were last held between November 2011 and January 2012 which was later dissolved. The next parliamentary election will be held within 6 months of the constitution's ratification on 18 January 2014. Originally, the parliament was to be formed before the president was elected, but interim president Adly Mansour pushed the date. The Egyptian presidential election, 2014, took place on 26–28 May 2014. Official figures showed a turnout of 25,578,233 or 47.5%, with Abdel Fattah el-Sisi winning with 23.78 million votes, or 96.91% compared to 757,511 (3.09%) for Hamdeen Sabahi.

There are both practical and theoretical difficulties in determining h. The practical difficulties can be illustrated by the fact that the two most accurate methods, the watt balance and the X-ray crystal density method, do not appear to agree with one another. The most likely reason is that the measurement uncertainty for one (or both) of the methods has been estimated too low – it is (or they are) not as precise as is currently believed – but for the time being there is no indication which method is at fault.
