Hierarchy of hazard control is a system used in industry to prioritize possible interventions to minimize or eliminate exposure to hazards. [ a ] It is a widely accepted system promoted by numerous safety organizations.
Ascending on a decompression buoy while slightly negatively buoyant makes accurate depth and ascent rate control relatively simple, by maintaining light tension on the line as it is reeled in, at the cost of carrying the equipment, a slightly longer time at depth during deployment, a few litres of gas for inflation, and the competence to deploy ...
Decompression in the context of diving derives from the reduction in ambient pressure experienced by the diver during the ascent at the end of a dive or hyperbaric exposure and refers to both the reduction in pressure and the process of allowing dissolved inert gases to be eliminated from the tissues during this reduction in pressure.
In cognitive science and neuropsychology, executive functions (collectively referred to as executive function and cognitive control) are a set of cognitive processes that support goal-directed behavior, by regulating thoughts and actions through cognitive control, selecting and successfully monitoring actions that facilitate the attainment of chosen objectives.
A A-grade Also aid climbing grade. The technical difficulty grading system for aid climbing (both for "original" and an adapted version for "new wave"), which goes: A0, A1, A2, A3, A4, A5 and up to A6 (for "new wave"). See C-grade. Abalakov thread Abalakov thread Also V-thread. A type of anchor used in abseiling especially in winter and in ice climbing. ABD Also assisted braking device. A term ...
There are three common methods used to determine sensory thresholds: [2] Method of Limits: In the first step, the subject is stimulated by strong, easily detectable stimuli that are decreased stepwise (descending sequence) until they cannot detect the stimulus. Then another stimulation sequence is applied called ascending sequence.
The corticobulbar (or corticonuclear) tract is a two-neuron white matter motor pathway connecting the motor cortex in the cerebral cortex to the medullary pyramids, which are part of the brainstem's medulla oblongata (also called "bulbar") region, and are primarily involved in carrying the motor function of the non-oculomotor cranial nerves, like muscles of the face, head and neck.
The cerebral peduncles (In Latin, ped-means 'foot'.) are the two stalks that attach the cerebrum to the brainstem. [1] They are structures at the front of the midbrain which arise from the ventral pons and contain the large ascending (sensory) and descending (motor) tracts that run to and from the cerebrum from the pons.
