The task's priority is set to the priority ceiling of the resource, thus no task that may lock the resource is able to get scheduled. This ensures the OCPP property that "A task can only lock a resource if its dynamic priority is higher than the priority ceilings of all resources locked by other tasks".
Stretcher course (Stretching course): This is a course made up of a row of stretchers. [1] This is the simplest arrangement of masonry units. If the wall is two wythes thick, one header is used to bind the two wythes together. [3] Header course: This is a course made up of a row of headers. [1]
A bunghole is a hole bored in a liquid-tight barrel to remove contents. The hole is capped with a cork or cork-like stopper called a bung. Acceptable usage includes other access points that may be capped with alternate materials providing an air- or water-tight access to other vessels.
Fire blocking or firestopping is a system of supplemental components in a wood-framed wall or ceiling, which prevents the rapid propagation of fire within a combustible framing cavity to other areas. Description and function
A ceiling can also be the upper limit of a tunnel. The most common type of ceiling is the dropped ceiling, [citation needed] which is suspended from structural elements above. Panels of drywall are fastened either directly to the ceiling joists or to a few layers of moisture-proof plywood which are then attached to the joists. Pipework or ducts ...
An older, less common type of dropped ceiling is the concealed grid system, which uses a method of interlocking panels into one another and the grid with the use of small strips of metal called 'splines', thus making it difficult to remove panels to gain access above the ceiling without damaging the installation or the panels. Normally, they ...
A gypsum block is made of gypsum plaster and water. The manufacturing process [1] is automated at production plants where raw gypsum (CaSO 4 ·2H 2 O) is ground and dried, then heated to remove three-quarters of the bound water and thus transformed into calcium sulfate hemihydrate (CaSO 4 ·½H 2 O), also known as gypsum plaster, stucco, calcined gypsum or plaster of Paris.
The findings clearly demonstrated that moisture absorption during the rainy season is confined to the surface layers and has no effect on the cork's thermal insulation performance. Other research has focused on cork-based composites. The insulation used in the studies by Cherki et al. [12] and Monir et al., [13] is a cork-gypsum composite ...
