After 22 years of eruption at Kilauea Volcano, Hawai'i, an environmental, epidemiological, and ethnographic study was conducted to assess for adverse health effects from chronic exposure to volcanogernc air pollution. Environmental data from 2003 indicated that Kau District, from 37 to 74 km downwind from the eruption, was being exposed...
Given image data of a fluid flow, the flow field, < u, v >, governing the evolution of the system can be estimated using a variational approach to optical flow. Assuming that the flow field governing the advection is the symplectic gradient of a stream function or the gradient of...
The purpose of this study was to investigate the distribution
and magnitude of scattered radiation from a typical
mobile radiographic examination as an aid in evaluating
the potential health hazards of the scattered radiation.
Also discussed are current radiation protection standards and
recommendations for mobile radiography.
A Manonite phantom represented...
Increasing numbers of individuals aspire to, seek out, and need a college degree in order to be competitive in the job market (Goyette, 2008; U.S. Department of Education, 2013). College degrees provide access to economic, social, and health benefits (Abel & Deitz, 2014; Autor, 2014). The United States also needs...
In many regions of the world, a significant portion of the surface water originates in mountain headwaters where the timing and magnitude of streamflow is largely dictated by the seasonal storage of precipitation as snowpack and long-term storage as glaciers. Accumulation, persistence, and melt of snow and ice are functions...
Converting CO2 to valuable materials is attractive.Herein, we report using simple metallothermic reactions to reduce atmospheric CO2 to dense nanoporous graphene. By using a Zn/Mg mixture as a reductant, the resulted nanoporous graphene exhibits highly desirable properties: high specific surface area of 1900 m2/g, a great conductivity of 1050 S/m...
