Citizens Band Radio
Citizens band radio (also known as CB radio), used in many countries, is a land mobile radio system, a system allowing short-distance person-to-many persons bidirectional voice communication among individuals, using two way radios operating on 40 channels near 27  MHz (11 m) in the high frequency (a.k.a. shortwave) band. Citizens band is distinct from other personal radio service allocations such as FRS, GMRS, MURS, UHF CB and the Amateur Radio Service ( "ham" radio). In many countries, CB operation does not require a license, and (unlike amateur radio) it may be used for business or personal communications. Like many other land mobile radio services, multiple radios in a local area share a single frequency channel, but only one can transmit at a time. The radio is normally in receive mode to receive transmissions of other radios on the channel; when users want to talk they press a " push to talk" button on their radio, which turns on their transmitter. Users ...

Cannabinoids
Cannabinoids () are several structural classes of compounds found in the cannabis plant primarily and most animal organisms (although insects lack such receptors) or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary intoxicating compound in cannabis. Cannabidiol (CBD) is a major constituent of temperate Cannabis plants and a minor constituent in tropical varieties. At least 113 distinct phytocannabinoids have been isolated from cannabis, although only four (i.e., THCA, CBDA, CBCA and their common precursor CBGA) have been demonstrated to have a biogenetic origin. It was reported in 2020 that phytocannabinoids can be found in other plants such as rhododendron, licorice and liverwort, and earlier in Echinacea. Phytocannabinoids are multi-ring phenolic compounds structurally related to THC, but endocannabinoids are fatty acid derivatives. Nonclassical synthetic cannabinoids (cannabimimetics) include ...

CB-class Midget Submarine
The CB class was a group of midget submarines built for the Italian Navy during World War II. However, they were also used by several other navies, seeing action in the Mediterranean and in the Black Sea. Construction and specifications The submarines were designed and built by Caproni. They were used as coastal defence units, being a significant improvement of the previous . Each unit had a standard (surfaced) displacement of 35.4 tons and a submerged displacement of 44.3 tons. They measured in length, had a beam of and a draught of . Power plant consisted of one Isotta Fraschini diesel engine and one Brown Boveri electric motor, both generating a total of powering a single shaft, resulting in a surfaced top speed of and a submerged top speed of . Each boat was armed with two externally-mounted torpedoes, each tube could be reloaded without removing the vessel from water. The two torpedoes could also be replaced by two mines. Each boat had a crew of four, aided in navig ...

Cell Broadcast
Cell Broadcast (CB) is a method of sending messages to multiple mobile telephone users in a defined area at the same time. It is defined by the ETSI’s GSM committee and 3GPP and is part of the 2G, 3G, 4G LTE (telecommunication) and 5G standards. It is also known as Short Message Service-Cell Broadcast (SMS-CB) or CB SMS. Unlike Short Message Service-Point to Point (SMS-PP), Cell Broadcast is a one-to-many geo-targeted and geo-fenced messaging service. History Cell Broadcast messaging was first demonstrated in Paris in 1997. Some mobile operators used Cell Broadcast for communicating the area code of the antenna cell to the mobile user (via channel 050), for nationwide or citywide alerting, weather reports, mass messaging, location-based news, etc. Cell broadcast has been widely deployed since 2008 by major Asian, US, Canadian, South American and European network operators. Not all operators have the Cell Broadcast messaging function activated in their network yet, bu ...

Circuit Breaker
A circuit breaker is an electrical safety device designed to protect an electrical circuit from damage caused by an overcurrent or short circuit. Its basic function is to interrupt current flow to protect equipment and to prevent the risk of fire. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset (either manually or automatically) to resume normal operation. Circuit breakers are made in varying sizes, from small devices that protect low-current circuits or individual household appliances, to large switchgear designed to protect high voltage circuits feeding an entire city. The generic function of a circuit breaker, or fuse, as an automatic means of removing power from a faulty system, is often abbreviated as OCPD (Over Current Protection Device). Origins An early form of circuit breaker was described by Thomas Edison in an 1879 patent application, although his commercial power distribution system used fuses. Its purpose was ...

Carte Bancaire
''Groupement des cartes bancaires CB'' ("CB Bank card Group"), also known as simply CB, is France's national interbank network, with over 46,000 ATMs and over 1 million EFTPOS acceptance points. ''Carte Bleue'' Visa is a brand often associated with CB. In fact, all Carte Bleue cards are part of CB but not all CB cards are Carte Bleue (they could also be Mastercard). CB offers the ATM and EFTPOS networking infrastructure, while Carte Bleue is the debit card or mode of payment. CB GIE was created in 1984 by the six founding banks of Carte Bleue, plus Crédit Agricole and Crédit Mutuel. Since 1992, all CB cards are smart cards; France was the first country to bring into the mainstream the use of smart cards with PIN verification in lieu of magnetic stripe cards and signature verification. In an example of a genericized trademark, it is commonplace in France to refer to any payment card as a carte bleue, whether or not this is in fact the case. See also * Carte Bleue ''Ca ...

Christianssands Bryggeri
Christianssands Bryggeri (or CB, Kristiansand's Brewery) is a Norwegian brewery centred in Kristiansand. Together with Hansa Bryggeri in Bergen and Borg Bryggerier in Sarpsborg it makes up Hansa Borg Bryggerier AS, which is the second largest group of breweries in Norway, next to Ringnes (which is ownd by Carlsberg). CB was created in 1856 by consul Ole Jacob Mørch. In 1859 he had to sell the brewery, together with the rest of his enterprises, as a consequence of hard times following the Crimean War. The brewery was sold to consul Jørgen Christiansen, who finished building the brewery and started production in the autumn of 1859. Kristiansand had about 11,000 inhabitants at this time and the brewery became a successful business. The Christiansen family led the enterprise for five generations until 1964. After this the shares were sold to Tou Brewery in Stavanger. Since then CB has had several owners: a group of investors called ''Sørlandvekst'', the Swedish brewery Spendrups, ...

Henry Campbell-Bannerman
Sir Henry Campbell-Bannerman (né Campbell; 7 September 183622 April 1908) was a British statesman and Liberal politician. He served as the prime minister of the United Kingdom from 1905 to 1908 and leader of the Liberal Party from 1899 to 1908. He also served as secretary of state for war twice, in the cabinets of Gladstone and Rosebery.

Capacity Building
Capacity building (or capacity development, capacity strengthening) is the improvement in an individual's or organization's facility (or capability) "to produce, perform or deploy". The terms ''capacity building'' and ''capacity development'' have often been used interchangeably, although a publication by OECD-DAC stated in 2006 that ''capacity development'' was the preferable term. Since the 1950s, international organizations, governments, non-governmental organizations (NGOs) and communities use the concept of capacity building as part of " social and economic development" in national and subnational plans. The United Nations Development Programme defines itself by "capacity development" in the sense of "'how UNDP works" to fulfill its mission. The UN system applies it in almost every sector, including several of the Sustainable Development Goals to be achieved by 2030. For example, the Sustainable Development Goal 17 advocates for enhanced international support for capacity b ...

Block Coefficient
A hull is the watertight body of a ship, boat, or flying boat. The hull may open at the top (such as a dinghy), or it may be fully or partially covered with a deck. Atop the deck may be a deckhouse and other superstructures, such as a funnel, derrick, or mast. The line where the hull meets the water surface is called the waterline. General features There is a wide variety of hull types that are chosen for suitability for different usages, the hull shape being dependent upon the needs of the design. Shapes range from a nearly perfect box in the case of scow barges to a needle-sharp surface of revolution in the case of a racing multihull sailboat. The shape is chosen to strike a balance between cost, hydrostatic considerations (accommodation, load carrying, and stability), hydrodynamics (speed, power requirements, and motion and behavior in a seaway) and special considerations for the ship's role, such as the rounded bow of an icebreaker or the flat bottom of a landing craft.
