Drive Train Innovations for the Next Generation of Wind Turbines

submitted by: RASEIBoulder
Summary: As tax credits expire for wind energy, the ability to compete with established energy sources is critical. All wind turbine manufacturers are examining their next generation turbines with an eye towards reducing their cost, increasing energy production, and improving reliability. Because the drive train accounts for such a large part of the rotor nacelle assembly cost, it has become a prime target for design change. Drive train innovations which reduce cost, increase energy...

The Stanford Healthy Neighborhood Discovery Tool: A Computerized Tool to Assess Active Living Environments

submitted by: mbuman
Background: The built environment can influence physical activity, particularly among older populations with impaired mobility. Existing tools to assess environmental features associated with walkability are often cumbersome, require extensive training, and are not readily available for use by community residents. Purpose: This project aimed to develop and evaluate the utility of a computerized, tablet-based participatory tool designed to engage older residents in identifying neighborhood...

Geomapping reveals environmental influence on behaviors and cancer risk

submitted by: mdanderson

In her research, Lorraine Reitzel, Ph.D., uses geographic information systems technology, with the help of Seann Regan, to obtain information about a geographic area. This allows her to better understand why people engage in certain behaviors and how their environment impacts health and cancer risk.

Objective Assessment of Obesogenic Environments in Youth: Geographic Information System Methods and Spatial Findings from the Neighborhood Impact on Kids Study

submitted by: Lawrence Frank
Background GIS-based walkability measures designed to explain active travel fail to capture “playability” and proximity to healthy food. These constructs should be considered when measuring potential child obesogenic environments. Purpose The aim of this study was to describe the development of GIS-based multicomponent physical activity and nutrition environment indicators of child obesogenic environments in the San Diego and Seattle regions. Methods Block group–level...

The Nature Explorers Chiricahua Part 2 of 12

submitted by: thenatureexplorers

Chiricahua is a "Sky Island" region that supports a variety of wildlife, some of which are more commonly thought of as denizens of subtropical habitats in Mexico or Central America. Even in February with snow and temperatures as low as -10°F we still found a cornucopia of nature, turkeys, woodpeckers, centipedes, pines, yuccas, agaves, and more.
