The critical thermal maximum (CTMax) of Peucetia viridans Hentz 1832 adult spiders was determined in the laboratory. Mean temperature at death was higher for gravid spiders (49.4 C) than for postparturient females (47.2 C) and males (46.9 C). Painted copper spider models placed in the environment to examine available temperatures predicted that spider body temperatures would rarely exceed 40 C ...

Background Hypothermia has been shown to provide cardiac protection after a STEMI insult in prior animal and post-hoc human studies. However, the influence of pre-reperfusion temperature on myocardial infarct size is not fully characterized. We employed cardiac MRI to determine the impact of moderate hypothermia (32C) upon infarct size in a porcine ischemia-reperfusion injury (IR) model using a...

Models for human perception of thermal environments included in so-called thermal comfort standards are either based on principles of thermal heat balance, or on large empirical datasets that include human adaptations to different thermal environments (i.e. so-called adaptive approach). The framework for an adaptive thermal heat balance model (ATHB) combines these 2 approaches, improves the pre...

A major tenet of the recreation specialization framework is that people progress to higher stages of involvement over time. Results from recent studies suggest that involvement may actually be marked by stability or decline. Little is known about the extent to which people progress in outdoor activities where objective standards of performance exist. The purpose of this study was to examine the...

threats are one of the most fundamental problems of our modern societies that daily will affect citizens in urban spaces. this becomes more problematic when the people in their everyday living spaces encounter with behaviors that cause lack of security and should have been feel comfort and their families used these spaces freely. this causes many problems for citizens. in today cities because o...

BACKGROUND Little is known about how physical activity and various high-risk behaviors of youth are associated, particularly in disadvantaged, minority neighborhoods. PURPOSE We examine whether fear, victimization, and perceived incivilities are associated with physical activity and outdoor recreation among Latino youth and whether involvement in physical activity is associated with delinquen...

With the current proliferation of wireless networks and mobile device technologies, the management of moving object databases to facilitate queries over these domains has been extensively studied. While current systems are concerned with tracing the precise location, or paths, of these objects, in many cases it is sufficient to know that the approximate location or path of a moving object is, w...

Outdoor leisure activities are important for public health as well as family cohesiveness, yet environmental factors may easily affect someone’s ability to participate in such activities. We explored this with a focus on the social web-based treasure hunt game called Geocaching. We collected data on all US and Canadian geocaches from OpenCaching.com and conducted an online survey with twenty ge...
