A mobile phone tower in Qatif. Telephones - main lines in use: 011 463,3507 (2011 - source: ITU) . Telephones - mobile cellular: 53,705,808 (2011 - source: ITU) note: In 2004, the Saudi Telecom Company (STC) monopolization was broken by authorizing Etihad Etisalat/Mobily to compete in mobile communication, in June 2009 GO Telecom (Etihad Atheeb Telecom) or "جو" also entered the market.
A Langmuir probe is a device used to determine the electron temperature, electron density, and electric potential of a plasma. It works by inserting one or more electrodes into a plasma, with a constant or time-varying electric potential between the various electrodes or between them and the surrounding vessel.
Dual Segmented Langmuir Probe (DSLP) is an instrument developed primarily by Czech researchers and engineers to study the magnetospheric background plasma flown on board the spacecraft of the European Space Agency Proba 2. [1] Data acquired by DSLP will be used to reach these specific scientific goals: [2]

In physical oceanography, Langmuir circulation consists of a series of shallow, slow, counter-rotating vortices at the ocean's surface aligned with the wind. These circulations are developed when wind blows steadily over the sea surface.
Plasma oscillations, also known as Langmuir waves (after Irving Langmuir), are rapid oscillations of the electron density in conducting media such as plasmas or metals in the ultraviolet region. The oscillations can be described as an instability in the dielectric function of a free electron gas. The frequency depends only weakly on the ...
For ideal both phases – no lateral interactions, homogeneous surface – the composition of a surface phase for a binary liquid system in contact with solid surface is given by a classic Everett isotherm equation (being a simple analogue of Langmuir equation), where the components are interchangeable (i.e. "1" may be exchanged to "2") without ...
This is a discussion of telephone numbers in the Kingdom of Saudi Arabia. The country's calling code is +966. In addition to a numbering plan, there are also dedicated numbers or number formats for Internet services, toll-free numbers , and public or emergency services.
