Citizens Band Radio
Citizens band radio (CB radio) is a land mobile radio system, a system allowing short-distance one-to-many bidirectional voice communication among individuals, using two-way radios operating near 27 MHz (or the 11-m wavelength) in the high frequency or 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 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 communicate they press a "push to talk" button on their radio, which turns on their transmitter. Users on a channel must take turns transmitting. In the US and Canada, and in the EU and th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cannabinoids
Cannabinoids () are several structural classes of compounds found primarily in the ''Cannabis'' plant or as synthetic compounds. The most notable cannabinoid is the phytocannabinoid tetrahydrocannabinol (THC) (delta-9-THC), the primary psychoactive compound in cannabis. Cannabidiol (CBD) is also a major constituent of temperate cannabis plants and a minor constituent in tropical varieties. At least 100 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 aminoalkylindoles, 1,5-diarylpyrazoles, quinolines, a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
CB-class Midget Submarine
The CB class was a group of midget submarines built for the Regia Marina, Italian Navy during World War II.

Cell Broadcast
Cell Broadcast (CB) is a method of simultaneously sending Short Message Service, short messages to multiple mobile telephone users in a defined area. It is defined by the ETSI's GSM committee and 3GPP and is part of the 2G, 3G, 4G 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 Point-to-multipoint communication, one-to-many geo-targeted and geo-fenced messaging service. Cell Broadcast technology is widely used for Emergency population warning, public warning systems. 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 service, location-based news, etc. Cell broadcast has been widely deployed since 2008 by major Asian, US, Ca ...

Circuit Breaker
A circuit breaker is an electrical safety device designed to protect an Electrical network, electrical circuit from damage caused by current in excess of that which the equipment can safely carry (overcurrent). Its basic function is to interrupt current flow to protect equipment and to prevent fire. Unlike a fuse (electrical), 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 commonly installed in distribution boards. Apart from its safety purpose, a circuit breaker is also often used as a main switch to manually disconnect ("rack out") and connect ("rack in") electrical power to a whole electrical sub-network. Circuit breakers are made in varying current ratings, from devices that protect low-current circuits or individual household appliances, to switchgear designed to protect high voltage, high-voltage circuits feeding an entire city. Any device which pr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Carte Bancaire
The 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. Brand design The CB logo was initially designed in 1967 by the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

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 Development Assistance Committee, 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 "Socioeconomics, social and economic development" in national and subnational plans. The United Nations Development Programme defines itself by "capacity development" in the sense of "'how United Nations Development Programme, 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 Develo ...
