The technical symposium, Nanomaterials: Implications for Environmental and Occupational Health, was developed to address the issue of nanotechnology safety and to acknowledge and assess environmental health implications of the growing number of consum . . .

The technical symposium, Community Exposures to Environmental Hazards, was developed to address the issue of community exposures to chemical hazards and to physical hazards (such as radiation and noise) created by local industrial activities. The symp . . .

The technical symposium, Regulating Environmental Pollutants: Perchlorates and other Thyroid-active Chemicals, was developed to address the issue of the increasing exposure of humans in industrialized nations to a class of chemicals called endocrine d . . .

The technical symposium, Drinking Water Policy in California: Environmental & Occupational Health Aspects, was developed to address the issue of increasing drought in California and the impact drought is having on water and wastewater policy. The symp . . .

Large scale anticyclonic vortices concentrate solid material in disks and may thus behave as a route for fast planet formation. The debate over their 3D stability in recent years has lead to the conclusion that they are stable to 3D perturbations prov . . .

Using a novel concurrent multiscale approach we demonstrate that the local environment of transition-metal solutes in refractory bcc metals has a large effect on the mobility and slip paths of dislocation. The results reveal that solid solutes or nano . . .

We analyze a unique 9 hr sequence of near simultaneous, high resolution and high cadence G-band and K-line SVST solar filtergrams together with magnetograms of lower cadence and resolution. We focus on a region of the solar surface that includes both . . .

Hydrogen adsorption in nanotubes has aroused tremendous interest recently due its potential impact for hydrogen storage in carbon nanotubes. Theoretical calculations based on density functional theory can offer unique insight for the atomic structures . . .

We study properties of intensity fluctuations in NOAA Active Region 11250 observed on 13 July 2011 starting at UT 13:32. Included are data obtained in the EUV bands of the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory (SDO/AIA) . . .
