The child sustained a spiral fracture resulting from a rotational injury while running or playing. A centrifugal pump is designed to move the fluid by means of transfer of the rotational energy. Muscles in the shoulder help control the front-to-back, side-to-side, and rotational movements of the humerus. Revolving, rotating and spinning around around and aroundidiom backspin birl centrifugal reel revolving rotary rotate rotation rotative spin spiral swim swing swizzle twirl twirling twirly underspin rotationaladjective (SYSTEM)relating to a system in which farmers regularly change which crops they grow in a field or which areas they keep animals in: It is usually used as a rotational crop, meaning it is planted every four to five years between other crops. They have started to adopt conservation practices such as rotational grazing systems. relating to a system in which different people do the same job at different times: The company has crews working on a rotational basis doing inspections continually. The team coach guards against burn-out by using a rotational system. They use a rotational grazing programme to better utilize seasonal grasses. Rotational assignments keep them on their toes and help them bring a fresh perspective to different parts of the business. Changing about-face about-turn alterable altered alternate churn disturb make an about-turn make something into something malleable meta metamorphose morph pervert revolutionize rollback rotation sanitization semi-domesticated transcribe Related wordsrotate rotation rotational | Business Englishrotational adjective WORKPLACE, HRuk /rəʊˈteɪʃənəl/us relating to a system in which the person who does a particular job is regularly changed: The shifts work on a rotational basis. Depending on the department, some recruits will participate in rotational placements. Examples of rotationalrotational Intensive rotational grazing is an example of a sustainable agricultural practice that takes a systems approach. The effect of cropping sequences and rotational management : an economic comparison of conventional, integrated and organic systems. A purely elastic instability apparently also occurs by a similar mechanism in other rotational shearing flows, namely concentric plate-and-plate flow and concentric cone-and-plate flow. This variation in paddle rotational velocity is monitored by an optical encoder and used to infer wind direction and velocity. The homogeneity of the plasma is guaranteed by the assumed translational and rotational invariances. To this end, rotational constants, dipole moments and infrared frequencies were calculated. As for rotational constants, calibration is necessary to obtain accurate frequencies. The main expected challenges would be the selection of rotational coordinates and derivation of the appropriate mass matrix. We notice that the assumption of rotational symmetry of the perturbations has considerably reduced the amount of algebraic work involved. A flexible jointed link is attached to its rotational joint moving perpendicular to the horizontal plane, and its other joints are fixed. The minimum radius obtained from the rotational solution is larger than obtained from the irrotational solution, even further narrowing the supersonic region of the vortex. This latter quantity cannot in general be determined analytically for waves on a rotational flow. Local shear acts in addition to global magnetic shear, the latter being a result of radial variation of the rotational transform. By supplying a winding action - rather than direct axial traction - rotational manoeuvres will achieve forward motion even without traction on the fetal head. The full threedimensional problem involving an arbitrarily given rotational symmetric external force field is considered for an arbitrary steady shear flow with vanishing axial velocity.
