night work can have a significant impact on health, well-being, performance and occupational safety of workers. night workers often complain about the sleep disorder characterized by excessive sleepiness.  the aim of the study was to determine the level of sleepiness among night workers and investigate its relationship with oral temperature in a hot industry. this cross-sectional study involved...

Abstract. We investigate if the presence of meteoric smoke particles (MSPs) influences electron temperature during artificial heating in D-region. By transferring energy powerful high-frequency radio waves into thermal electrons, increases temperature. Artificial depends on height variation density. The MSPs can influence density through charging by which reduce number free electrons and even r...

Chronodisruption deteriorates the health and wellbeing of shift workers. Artificial light at night lack during day are major contributors to chronodisruption need be optimized in work scenarios. Here, we present one solution for a lighting automation system an industrial production workplace. The setting is rapidly rotating environment with morning, evening, shifts. We describe procedure specif...

Civil aviation operators have expressed an increased interest in conducting night operations with night vision imaging systems. The development of special operational concepts, hardware requirements, training requirements, and regulatory change and oversight is necessary to control for the known performance constraints associated with these devices. In 2001, the Aerospace Medical Association in...

We have measured the illuminance (brightness) of seven neonatal units during both the day and the night. When the units were lit solely by fluorescent tubes the mean illuminance was 348 lux (range 192-690). During the day the mean illuminance was 470 lux (range 236-905). The high dependency regions in four of the seven units were significantly brighter than the corresponding low dependency nurs...

The increasing use of electric lights has modified the natural light environment dramatically, posing novel challenges to both humans and wildlife. Indeed, several biomedical studies have linked artificial light at night to the disruption of circadian rhythms, with important consequences for human health, such as the increasing occurrence of metabolic syndromes, cancer and reduced immunity. In ...

The pattern of locomotion activity was studied in Triatoma infestans, in relation to the use of an artificial refuge offered to the bugs in an experimental arena. In assays performed with insects that had a post-ecdysis starvation period of 1 week, the activity was low and mainly related to refuge leaving or entering. Insects that had gone through a longer period of starvation (6 weeks) exhibit...

Research inquiries of links between the built environment and population health have largely focused onphysical activity and social connectedness, associated health risks or benefits, and resultant chronic diseases; as well as access to healthy food, exposure to green views or green space, blue space, noise abatement, air pollution and biodiversity. Artificial light at night (ALAN) is mentioned...

Each year more than 250,000 infants in the United States are exposed to artificial lighting in hospital nurseries with little consideration given to environmental lighting cycles. Essential in determining whether environmental lighting cycles need to be considered in hospital nurseries is identifying when the infant's endogenous circadian clock becomes responsive to light. Using a non-human pri...

Objective: This study aims to explore the effects of light stress on the expression of Kisspeptin/GnRH in rat hypothalamus. Methods: The rat model of chronic stress was established through artificial illumination time. The rats were divided into control group, continuous light group, interval light group and reverse day and night group randomly. The expression levels of Kisspeptin and GnRH in r...
