BACKGROUND Question order might affect self-reported regular physical activity (PA) measured with items from the Behavioral Risk Factor Surveillance System (BRFSS) PA module. METHODS A telephone survey was conducted using 2 forms (N = 1004, N = 212) with varying PA question order. The standard form presented moderate-PA, vigorous-PA, and walking questions, in that order, whereas the alternate...

BACKGROUND Retrospective and cross-sectional data suggest that vigorous exertion can trigger cardiac arrest or sudden death and that habitual exercise may diminish this risk. However, the role of physical activity in precipitating or preventing sudden death has not been assessed prospectively in a large number of subjects. METHODS We used a prospective, nested case-crossover design within the...

The bioreduction of solid TNT by a Pseudomonas fluorescens strain was investigated in a stirred tank reactor. Experiments in which TNT beads were the only solids present indicated that the biodegradation mechanism is dissolution followed by degradation in bulk solution. Dissolution may limit the overall rate, in which case degradation can be enhanced through increased agitation. Since soil slur...

Alien invasive species (AIS) and non-native are a prominent extended problem in wide range of areas Europe around the world. Centered Umia’s riparian forest, Galicia, we found at least three main AIS needing to be controlled harvested preserve biodiversity area. Previous studies probed that leaves bark selected species—Tradescantia fluminensis, Arundo donax, Eucalyptus globulus—have important a...

BACKGROUND Limited data exist directly comparing the relative benefits of moderate- and vigorous-intensity activities with all-cause and cardiovascular (CV) disease mortality rates when controlling for physical activity volume. METHODS AND RESULTS We followed 7979 men (Harvard Alumni Health Study, 1988-2008) and 38 671 women (Women's Health Study, 1992-2012), assessing their physical activity...

OBJECTIVES Vigorous physical activity is a well-known method to promote people s health. This research aims to investigate whether perceived neighborhood characteristics affect vigorous physical activity among adult Seoul residents (aged 19 to 64). METHODS Utilizing the 2005 Seoul Citizens Health Indicators Survey data, this study estimates the probability of vigorous physical activity. Parti...
