The Buckfast bee is a breed of honey bee, a cross of many subspecies and their strains, developed by Brother Adam (born Karl Kehrle in 1898 in Germany), who was in charge of beekeeping from 1919 at Buckfast Abbey in Devon in the United Kingdom.
The Carniolan honey bee (Apis mellifera carnica, Pollmann) is a subspecies of the European honey bee. The Carniolan honey bee is native to Slovenia , southern Austria , and parts of Albania , [ 1 ] Croatia , Bosnia and Herzegovina , Montenegro , parts of Serbia [ 2 ] , Hungary , parts of Romania [ 3 ] and North-East Italy .
The bond-preventing layer decouples the casing from the core. This allows the steel core to resist the full axial force developed in the bracing, as designed. The casing – through its flexural rigidity – provides lateral support against the flexural buckling of the core. It is typically made of concrete-filled steel tubes.
Buckling-restrained braced frame (BRBF) is a structural steel frame that provides lateral resistance to buckling, particularly during seismic activity. [1] The BRBF is typically a special case of a concentrically braced frame. Tests have demonstrated BRBF systems are highly effective for energy dissipation, while being vulnerable to large ...
In structural engineering, a rigid frame is the load-resisting skeleton constructed with straight or curved members interconnected by predominantly rigid connections, which resist movements induced at the joints of members.
Frame of the Crystal Palace. Beams and girders were made of wrought iron with I-beam cross-section. The material was rarely used for the columns, as the cast was both stronger under compression and cheaper, so a typical iron frame building in the second half of the 19th century had cast iron columns and wrought iron beams.
The National frames have a long top-bar to the frame (17 in or 430 mm) giving them long lugs of 1 + 1 ⁄ 2 in (38 mm) that rest on the runners. In its original form, the National hive provides 3 ⁄ 8 in (9.5 mm) bottom beespace—that is, the top surface of the frame bar is flush with the top of the box, and the lower surface of the frame is ...
A bent in American English is a transverse rigid frame (or similar structures such as three-hinged arches).Historically, bents were a common way of making a timber frame; they are still often used for such, and are also seen in small steel-frame buildings, where the term portal frame is more commonly used.
