Is level of neighbourhood green space associated with physical activity in green space?

Background There is accumulating evidence that greater availability of green space in a neighbourhood is associated with health benefits for the local population. One mechanism proposed for this association is that green space provides a venue for, and therefore encourages, physical activity. It has also been suggested that socio-economic health inequalities may be narrower in greener areas because of the equalised opportunity for physical activity green spaces provide. However, research exploring associations between the availability of green space and physical activity has produced mixed results. Limits to the assessment of the type and amount of physical activity which occurs specifically in green space may account for these mixed findings. This observational study was therefore concerned with the extent to which green space is a venue for physical activity and whether this could account for narrower socio-economic health inequalities in greener neighbourhoods.<p></p> Method Secondary analysis of cross sectional data on 3679 adults (16+) living in urban areas across Scotland matched with a neighbourhood level measure of green space availability. Associations between green space availability and both total physical activity, and activity specifically within green space, were explored using logistic regression models. Interactions between socio-economic position and physical activity were assessed. All models adjusted for age, sex and household income.<p></p> Results The availability of green space in a neighbourhood was not associated with total physical activity or that specifically in green space. There was no evidence that income-related inequalities in physical activity within green space were narrower in greener areas of Scotland.<p></p> Conclusion Physical activity may not be the main mechanism explaining the association between green space and health in Scotland. The direct effect of perceiving a natural environment on physiological and psychological health may offer an alternative explanation.<p></p&gt

Ice nucleus activity measurements of solid rocket motor exhaust particles

The ice Nucleus activity of exhaust particles generated from combustion of Space Shuttle propellant in small rocket motors has been measured. The activity at -20 C was substantially lower than that of aerosols generated by unpressurized combustion of propellant samples in previous studies. The activity decays rapidly with time and is decreased further in the presence of moist air. These tests corroborate the low effectivity ice nucleus measurement results obtained in the exhaust ground cloud of the Space Shuttle. Such low ice nucleus activity implies that Space Shuttle induced inadvertent weather modification via an ice phase process is extremely unlikely

THE INFLUENCE OF ‘GANG BARU’ TRADITIONAL MARKET ACTIVITIES IN THE USE OF PUBLIC SPACE IN SEMARANG CHINATOWN

Chinatown is one of the commercial district in Semarang city, which continues to grow in the city center. It’s a 'generator' that drives a wide variety of economic activities, also self-actualization and disclosure of aspiration, expression of the people. One landmark Semarang's Chinatown is the traditional markets Gang Baru. Activities in Gang Baru includes selling/trading, the parking, loading and unloading on public space. The purpose of this study to analyze the traditional market activity in the public space by taking the characteristics of the cultural space. There is a relationship and influence between the market activity with the condition of public spaces in Gang Baru traditional markets and surroundings. Market activity effects change the social society condition in the field of the economic activities, using the dwelling house to shophouse, social interaction takes place between merchants and owner shophouse. The majority of Chinese societies ethnic are receiving the traditional market activity Gang Baru because it is a cultural heritage activities that has historical value, they continue the family business in this market. The trade time for the activities of buying and selling traditional market in the Gang Baru street give a strong influence on public space. Market activity give effects the disruption of the circulation, use of the road and pedestrian areas to the activities of hawkers, parking and unloading of goods

Low-energy particle radiation environment at synchronous altitude

The degradation of thermal control coatings of satellites due to the effects of low energy charged particles in the space environment is discussed. Data obtained from ATS-5 satellite measurement of proton and electron fluxes are presented. The variations in electron density, proton density, and magnetic activity are presented to show correlations which exist between these space factors

M101: The Pinwheel Galaxy

This Hubble Space Telescope image of M101 showcases a spiral galaxy's well-known features. The text describes the features that are common to all spiral galaxies. In the accompanying educational activity, In Search of...Spiral Galaxies, students investigate the structure of spiral galaxies through a level 1 inquiry activity using the images and text from the lithograph and other resources. A level 1 inquiry activity can help prepare students to become independent thinkers. Educational levels: Middle school, High school

Suited for spacewalking: A teacher's guide with activities

This publication is an activity guide for teachers on spacesuits and spacewalking. It uses the intensive interest many children have in space exploration as a launching point for hands-on-opportunities. The guide begins with brief discussions of the space environment, the history of space walking, the Space Shuttle spacesuit, and working in space. These are followed by a series of activities that enable children to explore the space environment as well as the science and technology behind the functions of spacesuits. The activities are not rated for specific grade levels because they can be adapted for students of many ages. The guide concludes with a brief glossary as well as references and resources
