Background: Regrettably motorcyclists frequently suffer related significant injuries. Doctors who manage trauma will encounter victims of motorcycle accidents and many aspects of care are unique to these patients due to the protective and performance enhancing equipment used by motorcyclists. This review examines the patterns of major injuries suffered by motorcyclists, the unique aspects of airway, circulatory and spine management, and suggests some interventions, which may allow primary injury prevention for the future.
Data Source: Literature searches of the PubMed, EMBASE and Cochrane library with hand searches and author's experience.
Interventions: None.
Data Synthesis And Conclusions: The airway and (cervical and thoracolumbar) spine cannot be managed effectively in the helmeted patient with a speed hump in place and intubation by direct laryngoscopy is almost impossible with a speed hump in place. Helmets should be removed and the speed hump cut from the leathers. Leathers act as fracture splints, particularly for pelvis and lower extremities. Removal or extensive cutting away of the lower portion of leathers should be considered as part of "circulation", and only take place in a medical facility and in anticipation of circulatory deterioration. Motorcyclists sustaining thoracic spinal damage more frequently than cervical and spinal fractures at multiple levels are common. Back protectors are used commonly and these may be left in situ for extrication on a spinal board, but they should be removed in-hospital to allow full assessment. Injury prevention will require coordinated research and development of a number of key pieces of equipment and design in particular helmets, speed humps and clothing/textiles. In managing the injured motorcyclist in the pre or in-hospital settings, health professionals require greater awareness of the implications of such devices, which at the present time appears largely restricted to motorcycling enthusiasts.

Exposure to excessive whole-body vibration is linked to health issues and may result in increased rates of mortality and morbidity in infants. Newborn infants requiring specialized treatment at neonatal intensive care units often require transportation by road ambulance to specialized care centers, exposing the infants to potentially harmful vibration and noise. A standardized Neonatal Patient Transport System (NPTS) has been deployed in Ontario, Canada, that provides life saving equipment to patients and safe operation for the clinical care staff.

This article describes the phenomena affecting the wear of the rotor of the working mechanism in a hydraulic satellite motor. The basic geometrical relationships that allow the calculation of the coordinates of the points of contact between the satellite and the rotor and the curvature are presented. A method for calculating the number of contacts of the satellite teeth with the rotor teeth and of the satellite teeth with the curvature teeth during one revolution of the rotor is proposed.

The radiation characteristics of rotor-beam interaction noise are studied experimentally for low Reynolds number small-scale rotors in interaction with beams of different shapes, sizes, and downstream positions. The number of blades ranges from two to four. For the two-bladed rotor, the presence of the beam has no effect on the mean aerodynamic performance.

Herbivores shape plant invasions through impacts on demography and dispersal, yet only demographic mechanisms are well understood. Although herbivores negatively impact demography by definition, they can affect dispersal either negatively (e.g.

High-speed GMAW tends to be accompanied by periodic humping defects, thereby reducing the weld bead quality. A new method was proposed to actively control the weld pool flow for eliminating humping defects. A high-melting point solid pin was designed and inserted into the weld pool to stir the liquid metal during the welding process.
