The behaviour of the progenitor species of the pig and the anatomy and physiology of the porcine eye suggest that the domesticated pig is best adapted for dim levels of natural light. This knowledge can therefore be used to specify lighting for domesticated pigs kept either indoors or outdoors. In general, English law is based on sound scientific evidence. Pigs use vision to discriminate betwee...

Research on eliminating organic pollutants in water by using heterogeneous photocatalysts such as nano-TiO2 abound. However, the question is whether metabolites, resulting from optical dispersion of environmental pollutants, are still toxic to aquatic organisms. Therefore, this study was designed to evaluate the effect of a co-exposure to paraquat and TiO2-NPs on blood biochemical indices of co...

The inherent control flexibility implied by solid-state lighting – united with the rich details offered by sensor networks – prompts us to rethink lighting control. In this research, we propose several techniques for measuring work surface illuminance and ambient light using a sensor network. The primary goal of this research is to measure work surface illuminance without distraction to the use...

aims: work proper lighting means a safe, healthy and comfort conditions for work under a lighting system that includes qualitative and quantitative features. this study aimed to evaluate the surface local lighting of works and eye fatigue among research and development staffs of an automotive industry. instrument & methods: in this descriptive study in research and development department of an ...

background: the aims of this study were to evaluate the employees' subjective assessments of different aspects of lighting condition as well as task area illuminance in manufacturing plants. methods: this field study was conducted between march and may 2013 , in three packing plants (saveh, central iran). data were collected by questionnaire and measurement of the task area illuminance levels. ...

Reduction of energy use for assimilation lighting is one of the most urgent goals of current greenhouse horticulture in the Netherlands. In recent years numerous lighting systems have been tested in greenhouses, yet their efficiency has been very difficult to measure in practice. This simulation study evaluated a number of lighting strategies using a 3D light model for natural and artificial li...
