In Sweden the use of daytime running lights (DRL) was made mandatory on 1 October 1977 for all motor vehicles at once, during all seasons and for all areas. According to a study conducted by Andersson and Nilsson (1981) [Andersson and Nilsson. VTI Swedish Road and Transport Research Institute, Report No. 208A; 1981] the introduction of DRL resulted in a reduction of 11% of multiple accidents du...

Circadian phase resetting is sensitive to visual short wavelengths (450-480 nm). Selectively filtering this range of wavelengths may reduce circadian misalignment and sleep impairment during irregular light-dark schedules associated with shiftwork. We examined the effects of filtering short wavelengths (<480 nm) during night shifts on sleep and performance in nine nurses (five females and four ...

Long-term exercise training selectively alters serum cytokines involved in fever. Chronic exercise training has a number of effects on the immune system that may mimic the physiological response to fever. Female rats that voluntarily exercise on running wheels develop an elevated daytime core temperature after several weeks of training. It remains to be seen whether the elevation in daytime tem...

Chemical mutagenesis has provided an opportunity to develop and expand the repertoire of behavioural mutants for gene function studies. With this in mind, we have established a screen in mice for mutations affecting circadian rhythms, entrainment to light and other wheel-running parameters. The screen consists of an assessment of mouse wheel-running activity in a 12:12 h light/dark cycle for 7-...

To clarify the influence of yellow, green, and proportional yellow-green light on capture effect, western flower thrips, Frankliniella occidentalis (Pergande), were captured using different self-made sources in a greenhouse. The bio-activity effect thrips was regulated by analyzed to determine reasons for changes their light. results showed that thrips’ induced with same brightness positively c...

globally excessive consumption of hydrocarbon fuel in transport sector is a serious threat to the civilization due to paucity of fuel in future. also this growing use of vehicles for transport is contributing about 70% of total air pollution and causing environmental and ecological imbalances. thus the worldwide fast depletion of conventional energy resources and impact of emissions on environm...

The high frequency of red-light running and complex driving behaviors at the yellow onset at intersections cannot be explained solely by the dilemma zone and vehicle kinematics. In this paper, the author presented a red-light running prevention system which was based on artificial neural networks (ANNs) to approximate the complex driver behaviors during yellow and all-red clearance and serve as...
