Environmental Health: Action Needed to Sustain Agencies' Collaboration on Pharmaceuticals in Drinking Water

Description: A letter report issued by the Government Accountability Office with an abstract that begins "Drinking water in some metropolitan areas contains concentrations of pharmaceuticals, raising concerns about their potential impact on human health. The Safe Drinking Water Act (SDWA) authorizes the Environmental Protection Agency (EPA) to regulate contaminants, including pharmaceuticals, in public drinking water systems if they may adversely affect human health among other criteria. Pharmaceuticals may… more

Itinerant and localized magnetic moments in ferrimagnetic Mn{sub 2}CoGa thin films identified with x-ray magnetic linear dichroism: experiment and ab initio theory

Description: Epitaxial thin films of the half-metallic X{sub a}-compound Mn{sub 2}CoGa (Hg{sub 2}CuTi prototype) were prepared by dc magnetron co-sputtering with different heat treatments on MgO (001) substrates. High-quality #12;lms with a bulk magnetization of 1.95(5) {mu}{sub #22;}B per unit cell were obtained. The average Mn magnetic moment and the Co moment are parallel, in agreement with theory. The x-ray magnetic circular dichroism spectra agree with calculations based on density functional theory an… more

The influence of working gas pressure on interlayer mixing in magnetron-deposited Mo/Si multilayers

Description: Impact of Ar gas pressure (1-4 mTorr) on the growth of amorphous interlayers in Mo/Si multilayers deposited by magnetron sputtering was investigated by small-angle x-ray scattering ({lambda} = 0.154 nm) and methods of cross-sectional transmission electron microscopy. Some reduction of thickness of the amorphous inter-layers with Ar pressure increase was found, while composition of the layers was enriched with molybdenum. The interface modification resulted in raise of EUV reflectance of the Mo/… more

Engineering Glass Passivation Layers -Model Results

Description: The immobilization of radioactive waste into glass waste forms is a baseline process of nuclear waste management not only in the United States, but worldwide. The rate of radionuclide release from these glasses is a critical measure of the quality of the waste form. Over long-term tests and using extrapolations of ancient analogues, it has been shown that well designed glasses exhibit a dissolution rate that quickly decreases to a slow residual rate for the lifetime of the glass. The mechanisti… more

Disability Benefits Available Under the Social Security Disability Insurance (SSDI) and Veterans Disability Compensation (VDC) Programs

Description: Social Security Disability Insurance and Veterans Disability Compensation- administered by the Social Security Administration and the Department of Veterans Affairs respectively- are two of the largest federal disability programs, but strongly differ along several dimensions, including the populations served, how each program defines a "disability," as well as varying eligibility requirements. This report provides a description and comparative analysis of the Social Security Disability Administ… more
