Yet even in New York City and other U.S. urban areas, variation in particulate matter levels from week to week and from neighborhood to neighborhood makes many communities subject to serious health threats with every breath.
Eibich, P. and N. R. Ziebarth (2014): "Analyzing Regional Variation in Health Care Utilization Using (Rich Household Microdataa," Health Policy, (Special Issue: Geographic Variation in Health Care: 40 Years of Small-Area Variations), 114(11441143.
Therefore, the strain-dependent friction was attributed to the atomic scale contact area variations under the applied strain.
Mapping and statistical analysis revealed substantial clustering and small-area variations in the prevalence of DM in the City of Winnipeg.
This research indicates that a mobile saturation sampling network, when combined with proper modeling techniques, can uncover small area variations (e.g., 10 m) in particulate matter concentrations.
The originality of this study is to determine the indentation size effect and contact area variations on mechanical properties of HVOF sprayed WC-based coatings.
Pellet porosity and specific surface area variations caused both by sintering and chemical reaction have been determined for the manganese oxide-manganese sulfide system.
The eigenfrequencies of rods with certain area variations, subjected to classical boundary conditions, are obtained and the parametric space of the solutions obtained is studied.
A general approximate analytical solution is presented for transmission of plane sound waves in subsonic low Mach number ducts with axial ambient gradients and cross-sectional area variations.
