Mobile observation improves the accuracy and coverage of environmental monitoring, can locate track pollution sources. We conducted mobile monitoring to obtain real-time atmospheric pollutants (PM2.5, PM10, SO2, NO2, CO O3) in typical areas, which included a country park tourist attraction featuring an ancient town Yangtze River Delta Eco-Green Integrated Development Demonstration Zone (Demonst...

This paper analyzes day-of-week variations in concentrations of particulate matter (PM) in California. Because volatile organic compounds (VOCs) and oxides of nitrogen (NOx) are not only precursors of ozone (O3) but also of secondary PM, it is useful to know whether the variations by day of week in these precursors are also evident in PM data. Concentrations of PM < or = 10 microm (PM10) and < ...

OBJECTIVES To examine associations between fundamental movement skills and weekday and weekend physical activity among preschool children living in deprived communities. DESIGN Cross-sectional observation study. METHODS Six locomotor skills and 6 object-control skills were video-assessed using The Children's Activity and Movement in Preschool Study Motor Skills Protocol. Physical activity w...

As cited in papers on performance measurement and profiling [14], [15], computing power of desktop workstations is available, i.e. unused 50− 70% of the time – not only on weekends and during the night but also during busiest working hours. Since computing capacity steadily increases, these numbers are likely to grow. Usual resource request patterns, however are bursty, i.e. phases of multiple ...

Afterschool programs (ASPs)—also called out-of-school time (OST) programs—include a variety of program types, structured in numerous ways, designed to affect a variety of outcomes. As the name implies, such programs generally occur outside of mandated school hours, although some programs classified as afterschool or out-of-school may be part of a larger program where elements are delivered duri...

A substantial literature examines the social and environmental correlates of walking to school but less addresses walking outside the school commute. Using travel diary data from London, we examined social and environmental correlates of walking: to school; outside the school commute during term time; and during the summer and weekends. Living in a household without a car was associated with al...

Many dedicated scientists reject the concept of maintaining a “work-life balance.” They argue that work is actually a huge part of life. In the mindset of these scientists, weekdays and weekends are equally appropriate for working on their research. While we all have encountered such people, we may wonder about how frequent this condition is in other scientists in our field. This brief communic...

We report a case of pectin-induced occupational asthma in a 35-year-old man. His job involved mixing powdered pectin into a fruit puree during the manufacture of jam. Within minutes of adding pectin, he developed coryza, rhinorrhea, coughing, and wheezing. His symptoms cleared during weekends while away from work and improved with the use of a protective face mask at work. Peak flow rates were ...
