Digital subscriber line DSL redirects here. For other uses, see DSL (disambiguation) . Digital subscriber line (DSL; originally digital subscriber loop) is a family of technologies that are used to transmit digital data over telephone lines.his is possible because DSL uses higher frequency bands for data. On the customer premises, a DSL filter on each non-DSL outlet blocks any high-frequency interference to enable simultaneous use of the voice and DSL services.

xDSL Refers collectively to all types of digital subscriber lines, the two main categories being ADSL and SDSL. Two other types of xDSL technologies are High-data-rate DSL (HDSL) and Very high DSL (VDSL) .DSL is similar to ISDN inasmuch as both operate over existing copper telephone lines (POTS) and both require the short runs to a central telephone office (usually less than 20,000 feet).

- Total Photons, A Measure of Radioactivity One method used to measure the radioactivity of a sample is to count the photons that are emitted. Then, with proper calibration factors, the counts per minute (CPM) can be converted into units of radioactivity, curies or becquerels.

Radionuclide A radionuclide (radioactive nuclide, radioisotope or radioactive isotope) is an atom that has excess nuclear energy, making it unstable.adionuclides with suitable half-lives are used in nuclear medicine for both diagnosis and treatment. An imaging tracer made with radionuclides is called a radioactive tracer. A pharmaceutical drug made with radionuclides is called a radiopharmaceutical.

- The reflection of the beam creates some comet-tail reverberation artifacts, called B-lines or ultrasound lung comets. A B-line is a discrete, laser-like, vertical, hyperechoic image, that arises from the pleural line, extends to the bottom of the screen without fading, and moves synchronously with respiration.

Radiation therapy It is not to be confused with Radiation (pain) or Radiology. Radiation therapy or radiotherapy, often abbreviated RT, RTx, or XRT, is therapy using ionizing radiation, generally as part of cancer treatment to control or kill malignant cells and normally delivered by a linear accelerator. Radiation therapy may be curative in a number of types of cancer if they are localized to one area of the body.

How Much Money Do Top Bodybuilders Make? You can see a list of IFBB competitions for a better idea, and to see location differences. There are entry fees for competition participants, for example $150 for the 2012 GNC IFBB North American Championships, so with such small money on offer and a fair cost of entry, competitors are not there for the prize money.

Definition of 'radiocarbon' Definition of 'radiocarbon'. Word Frequency. radiocarbon (reɪdioʊkɑːʳbən ) also radio carbon. uncountable noun. Radiocarbon is a type of carbon which is radioactive, and which therefore breaks up slowly at a regular rate. Its presence in an object can be measured in order to find out how old the object is.

Digital subscriber line access multiplexer 1 The DSLAM port where the subscriber local loop is connected converts analog electrical signals to data traffic (upstream traffic for data upload) and data traffic to analog electrical signals (downstream for data download).ustomers connect to the DSLAM through ADSL modems or DSL routers, which are connected to the PSTN network via typical unshielded twisted pair telephone lines. Each DSLAM has multiple aggregation cards, and each such card can have multiple ports to which the customers' lines are connected.

Becquerel The becquerel (English: / b ɛ k ə ˈ r ɛ l /; symbol: Bq) is the SI derived unit of radioactivity. One becquerel is defined as the activity of a quantity of radioactive material in which one nucleus decays per second. The becquerel is therefore equivalent to an inverse second, s −1.

Radioactivity Radioactivity is the emission of radiation by unstable nuclei. That radiation may exist in the form of subatomic particles (primarily alpha and beta particles) or in the form of energy (primarily gamma rays). Radioactivity was discovered accidentally in 1896 by French physicist Henri Becquerel (1852–1908).
