A cross-sectional survey of musculoskeletal disorder hazard exposures and self-reported discomfort among on-shore wind turbine service technicians.

Background: Servicing and maintaining wind turbines may expose wind turbine technicians (wind techs) to musculoskeletal disorder (MSD) hazards. We aimed to characterise MSD hazard exposures and identify work elements that should be prioritised for MSD prevention efforts.

Methods: A cross-sectional online survey methodology gathered data from 144 wind techs based on a convenience, non-probability sampling approach.

Growth in Tobacco Control publications by authors from low- and middle-income countries.

Background: Research has contributed significantly to tobacco control in high-income nations, but has not yet played a comparable role in low- and middle-income countries (LMIC). In recent years, efforts have been devoted to building research capacity in LMICs. Using publication in Tobacco Control as a proxy for all tobacco control research, we examine whether research articles authored by scholars from LMICs and about LMIC issues have increased over the Journal's history.

Millimeter-wave effects on electric activity of crayfish stretch receptors.

The effects of super high frequency (SHF) microwaves (34-78 GHz) on rates of spontaneous firing of the slowly adapting, stretch-receptor neurons of crayfish were studied. Initially, irradiation of continuously perfused, fluid-cooled preparations at power densities to 250 mW/cm2 caused a transient decrease in the rate of spontaneous firing (the dynamic response). Subsequently, with extinction of the SHF field, the rate of firing increased, finally stabilizing at pre-exposure levels (stationary phase).

[Effect of electromagnetic SHF-radiation on the morphofunctional status of early mouse embryos].

A differential effect of 915 MHz microwave radiation with 500 Hz amplitude modulation of 1 ms pulses on the morphofunctional state of mouse 8-cell embryos has been shown. Then development is not disturbed by irradiation for 15 to 20 min. This effect is suggested to correlate with some changes in the properties of cell membranes as a result of possible local increases of temperature.
