BACKGROUND Influences of prenatal and early-life exposures to air pollution on cognition are not well understood. OBJECTIVES We examined associations of gestational and childhood exposure to traffic-related pollution with childhood cognition. METHODS We studied 1,109 mother-child pairs in Project Viva, a prospective birth cohort study in eastern Massachusetts (USA). In mid-childhood (mean a...
Abstract Light pollution is a phenomenon that affects both humans and the environment negatively. Currently there are no established means to calculate light pollution. This work proposes method for calculating levels of on facades buildings, specifically historical which most difficult light, using simulation techniques. The proposed methodology tested different grid densities concluded highes...
a r t i c l e i n f o This paper investigates image processing and pattern recognition techniques to estimate atmospheric visibility based on the visual content of images from off-the-shelf cameras. We propose a prediction model that first relates image contrast measured through standard image processing techniques to atmospheric transmission. This is then related to the most common measure of ...
This research deals with measuring the levels of visual pollution in Al-Kazimiya district and its surroundings, which differ from other regions terms intensity impact. Then addresses several solutions that will address problem reduce environmental effects on urban environment residents area. The researchers note there is a discrepancy manifestations between areas it also varies impact regions, ...

Linear improvement is to apply to the mean visibil...

Noisiness is an important experience in the product domain, because everyday products may contribute to noise pollution. Some products, such as a vacuum cleaner or a washing machine, make harsh and unpleasant sounds. Other products may be less noisy, but working together may be quite distracting and annoying for their users. In a broad context, noise refers to irrelevant or superfluous informat...
PURPOSE To investigate the association between exposure to traffic-related air pollution and use of spectacles (as a surrogate measure for myopia) in schoolchildren. METHODS We analyzed the impact of exposure to NO2 and PM2.5 light absorbance at home (predicted by land-use regression models) and exposure to NO2 and black carbon (BC) at school (measured by monitoring campaigns) on the use of s...
