The first demonstration of a BEC in weightlessness was achieved in 2008 at a drop tower in Bremen, Germany by a consortium of researchers led by Ernst M. Rasel from Leibniz University Hannover. [69] The same team demonstrated in 2017 the first creation of a Bose–Einstein condensate in space [ 70 ] and it is also the subject of two upcoming ...
An ecclesial base community is a relatively autonomous Christian religious group that operates according to a particular model of community, worship, and Bible study.The 1968 Medellín, Colombia, meeting of Latin American Council of Bishops played a major role in popularizing them under the name basic ecclesial communities (BECs; also base communities; Spanish: comunidades eclesiales de base).

[3] [4] BEC is termed an ecosystem classification as the approach integrates site, soil, and vegetation characteristics to develop and characterize all units. BEC has a strong application focus [ 5 ] and guides to classification and management of forests , grasslands and wetlands are available for much of the province to aid in identification ...
The manipulation of a Bose–Einstein condensate (BEC) using a standing light wave is an important technique in the field of atomic physics. A Bose-Einstein condensate is a state of matter that emerges when a group of atoms is cooled to extremely low temperatures, approaching absolute zero.
This can be achieved by cooling and magnetic or optical control of the system. Spectroscopy can detect shifts in peaks indicating thermodynamic phases with condensation. Quasiparticle BEC can be superfluids. Signs of such states include spatial and temporal coherence and polarization changes.
Superfluid vacuum theory (SVT), sometimes known as the BEC vacuum theory, is an approach in theoretical physics and quantum mechanics where the fundamental physical vacuum (non-removable background) is considered as a superfluid or as a Bose–Einstein condensate (BEC).
In battery-powered equipment, a battery eliminator circuit (BEC) is an electronic voltage regulator used to power a subsystem at a different voltage without the need for a supplemental battery. BECs are commonly used in radio-controlled models , which need separate voltages to power the motor and the RC equipment.
The BEC system is defined in terms of the Standard International Trade Classification system. The original BEC was published in 1971, and revised in 1976, 1986 and most recently in 1988. The top level categories of the BEC are as follows: BEC-1: Food and beverages; BEC-2: Industrial supplies not elsewhere specified; BEC-3: Fuels and lubricants
