Background: Being a cameraman is one of those occupations that expose people to musculoskeletal disorders (MSDs). Therefore, control measures should be taken to protect cameramen’s health. To solve the given problem, a vest was designed for cameramen to prevent MSDs by reducing the pressure and contact stress while carrying the camera on their shoulder. However, the usability of vest had ...

This model study addresses the change in pelagic calcium carbonate production (CaCO3, as calcite in the model) and dissolution in response to rising atmospheric CO2. The parameterization of CaCO3 production includes a dependency on the saturation state of seawater with respect to calcite. It was derived from laboratory and mesocosm studies on particulate organic and inorganic carbon production ...

We present dye visualizations of the wake behind a flexible plate flow when its leading edge is forced into harmonic heave motion. We show that, when the forcing amplitude is sufficiently large, a reverse Bénard-von Kármán vortex street is formed in the wake, indicative of the production of positive thrust.

The use of the 'PEP' mask with forced expiratory coughing was compared with conventional physiotherapy over a one month period. No difference was shown in symptom scores, sputum production, or simple lung function tests. The mask was well accepted and allowed independent treatment by older patients.

A study was carried out to examine the effects of forced running exercise in the growing stage in male ICR mice and of Astragalus membranaceus (As) on their immune functions. The mice were divided at 4 weeks of age into 4 groups. The first group of mice received forced running exercise (E-group), the second group was given As (As-group), the third group received the forced running exercise and ...
