Ranges of movement

Supply Air When designing workbenches, it is essential that the supply air face area be large enough to cover the contained area. Therefore it is important to have some indication of the operator s range of movements for all intended operations. Moreover, for efficient protection the supply airflow must be adequate to get a stable flow field that will not be affected by ambient disturbances. In industrial applications the suitable mean supply air velocities are typically between 0.2 and 0.45 m s h Low velocities should be used when the distance between the supply air unit and the operator is small or for cool supply air. High velocities are applicable at greater distances and in hot environments, with thermal comfort being considered. [Pg.977]

ADP. The hinge regions of myosin (referred to as flexible points at each end of S-2 in the legend to Figure 49-7) permit the large range of movement of S-1 and also allow S-1 to find actin filaments. [Pg.562]

In addition to finding the minima for each intermediate in a synthesis, it is also necessary to be able to analyse reactivity. This is a more difficult problem than conformation searching, because it is now possible for bonds to break. The range of movements available to the molecule is far larger, and it is also necessary to consider which bond will break most easily, and what factors are present which will drive the reaction forwards. If there are many competing reactions, then these calculations may have to be very precise in order to distinguish between them. [Pg.50]

In contrast with fast, strong predators, organisms with a limited range of movement, or limited control over their movements—those that cannot run away from potential predators—are well represented among the chemically defended (Table 1). Sessile marine invertebrates are particularly accomplished chemists these include in their ranks sponges, antho-zoan corals, crinoid echinoderms, polychaetes, bryozoans, brachiopods,... [Pg.14]

One of the first applications of ultrasound in medicine was the so-called ultrasonic massage introduced in Germany before the Second World War. This was introduced as a substitute for the hands of the masseur in patients who had suffered from fractures and similar injuries. Rubbing movements are capable of improving the circulation very considerably and help also to break down adhesions between muscles and their sheaths that limit the range of movement. The use of ultrasound for the treatment of sporting injuries, particularly strains and tennis elbow is now commonplace as equipment for this purpose is readily commercially available to the physiotherapist. This is one of the first uses of ultrasound in the treatment of medical problems and is part of a new field of medicine called therapeutic ultrasound [15]. [Pg.10]

Amygdala An anatomically coherent subsystem within the basal forebrain. Verbal and non-verbal expressions of fear and anger are interpreted by the amygdala. Cerebellum One of the seven parts of the brain that is responsible for muscle co-ordination and modulation of the force and range of movement. It is involved in the learning of motor skills. [Pg.3]

In many respects, the linker LI can be likened to a flexible hinge, a role consistent with a swinging head model proposed for IFs. In this model, segment 1A can (under appropriate conditions) split into two separate Q-helical strands, thereby maximizing the range of movement of the head domains and hence increasing their capacity to interact with various other cellular entities (Parry et al, 2002). [Pg.125]

Spasticity, if moderate to severe, may impede rehabilitation after stroke. Botulinum toxin has been shown in small studies to reduce tone and improve range of movement but robust evidence for improvement in function is lacking (van Kuijk et al. 2002). [Pg.277]

Horn The steady state is shifted, but I would say that in order for the inactivation to occur efficiently or in the right voltage range, you need the full range of movement of that S4 segment. Whether that is due to the inactivation gate binding inefficiently without that S4 movement, I don t know. [Pg.26]

Saturation can also occur mechanically within the g-cell if the moving element strikes a mechanical overtravel stop and can no longer move. While this is mechanically possible with all silicon micromachined g-cells, it is usually the least likely source of saturation. In order to provide good linearity the range of movement of the g-cell sensing elements is usually less than 2% of the total range and mechanical stops may be used to limit the movement to less than 2/3 of the total... [Pg.281]

By their very nature, tasks which enable one to measure spatiotemporal accuracy are complex or higher-level sensory-motor tasks. These place demands on a large number of lower-level PRs such as visual acuity, dynamic visual perception, range of movement, strength, simple reaction times, acceler-ation/deacceleration, static steadiness, dynamic steadiness, prediction, memory, open-loop movements, concentration span, attention switching, that is, central executive function or supervisory attentional system (multitask abilities), utilization of preview, and learning. [Pg.1265]

A well-fitted sport garment must not interfere, impede or restrict the body movement relative to the end use, sport activity and range of movement expected this is the ergonomic and utility wear comfort of clothing. When the garment impedes or restricts the body movement, it causes discomfort as well as increased metabolic cost (Ashdown, 2011). [Pg.101]
