BACKGROUND Enhancing community environments to support walking and bicycling serves as a promising approach to increase population levels of physical activity. However, few studies have simultaneously assessed perceptions and objectively measured environmental factors and their relative association with transportation or recreational physical activity. METHODS For this cross-sectional study, ...

OBJECTIVE Dependence on motorized forms of transportation may contribute to the worldwide obesity epidemic. Shifts in transportation patterns occurring in China provide an ideal opportunity to study the association between vehicle ownership and obesity. Our objective was to determine whether motorized forms of transportation promote obesity. RESEARCH METHODS AND PROCEDURES A multistage random...

This investigation described the effects of exercise, walking, and cycling for transportation, as well as the effect of overall nonexercise physical activity, on mortality in the Shanghai Women's Health Study (1997-2004). Women without heart disease, stroke, or cancer were followed for an average of 5.7 years (n = 67,143), and there were 1,091 deaths from all causes, 537 deaths from cancer, and...

The present paper gives an overview on actual developments of the application of piezoelectric components in transportation industry. During the last decades, piezoelectric materials made huge progress in entering commercial mass markets throughout all branches, where piezoelectrics are used as the basis materials for actuators as well as sensors. Especially in transportation industry, they fou...

In this paper, we deal with the production and transportation planning of a household appliances manufacturer that has production facilities and central stores for resellers in several sites in Europe. Each store can receive products from all production plants and it is not necessary that all products are produced in all production units. The transport between any two bases is done by trucks. F...

Exposure to traffic and traffic-related air pollution is associated with a wide array of health effects. Time spent in a vehicle, in active transportation, along roadsides, and in close proximity to traffic can substantially contribute to daily exposure to air pollutants. For this study, we evaluated daily time spent in transportation and traffic-influenced microenvironments by urban Canadians ...

Most studies of active aeolian processes on Mars have focused on dust [1], i.e., particles -1 [tm in diameter that are transported in suspension by wind. The presence of sand dunes on Mars [2-8] indicates that larger grains ( >60 _tm, transported primarily in saltation) are also present. Although indirect evidence suggests that some dunes may be active [9], definitive evidence is lacking. Nonet...

When I think of theword niche, phrases such as a “specialized place” or a “distinct segment” come to mind. When it was time to identify the theme for the 2014 Active Living Research (ALR) Conference, we thought about how some people consider the field of active living a niche area. Because of this, it is not entirely surprisingly that around the world, communities still lack sidewalks, pedestri...
