Environmental Life Cycle Assessment of a U.S. Hospital-based Radiology Practice.

Background Climate change, driven primarily by human-induced greenhouse gas (GHG) emissions, poses major risks to human health. Health care contributes 8.5% of GHG emissions in the United States.

Remote Density Measurements of Molten Salts via Neutron Radiography.

With an increased interest in the use of molten salts in both nuclear and non-nuclear systems, measuring important thermophysical properties of specific salt mixtures becomes critical in understanding salt performance and behavior. One of the more basic and significant thermophysical properties of a given salt system is density as a function of temperature. With this in mind, this work aims to present and layout a novel approach to measuring densities of molten salt systems using neutron radiography.

Crop wild relatives of the United States require urgent conservation action.

The contributions of crop wild relatives (CWR) to food security depend on their conservation and accessibility for use. The United States contains a diverse native flora of CWR, including those of important cereal, fruit, nut, oil, pulse, root and tuber, and vegetable crops, which may be threatened in their natural habitats and underrepresented in plant conservation repositories. To determine conservation priorities for these plants, we developed a national inventory, compiled occurrence information, modeled potential distributions, and conducted threat assessments and conservation gap analyses for 600 native taxa.

Crop Wild Relatives as Germplasm Resource for Cultivar Improvement in Mint ( L.).

is a strongly scented herb of the (formerly ) and includes about 30 species and hybrid species that are distributed or introduced throughout the globe. These fragrant plants have been selected throughout millennia for use by humans as herbs, spices, and pharmaceutical needs. The distilling of essential oils from mint began in Japan and England but has become a significant industrial product for the US, China, India, and other countries.

Strain-Specific Differences in Survival of spp. in Naturally Contaminated Turkey Feces and Water.

and are leading causes of human foodborne illness, with poultry as a major vehicle. Turkeys are frequently colonized with , but little is known about survival in turkey feces, even though fecal droppings are major vehicles for within-flock transmission as well as for environmental dissemination. Our objective was to examine survival of , including different strains, in freshly excreted feces from naturally colonized commercial turkey flocks and in suspensions of turkey feces in water from the turkey house.
