Impact of Secondary Prevention on Mortality in the Building Trades National Medical Screening Program: Effectiveness of Occupational High-Risk Management. [PDF]
Am J Ind MedABSTRACT Background Since 1997 the Building Trades National Medical Screening Program (BTMed) has offered medical exams to construction workers employed in US nuclear weapons facilities. The process consists of two steps: (1) a detailed work history interview; and (2) a medical exam.

Do Snow-Adapted Prey Facilitate Coexistence of the Sierra Nevada Red Fox With Sympatric Carnivores? [PDF]
Mol EcolABSTRACT Specialist species in alpine ecosystems may be increasingly threatened by climate‐driven habitat loss and encroachment by generalist competitors. Ecological theory predicts that niche differentiation through dietary specialisation can facilitate coexistence with generalist competitors.

Branching Out: Rabbit Models Provide Evidence for the Use of a Willow Cultivar (Salix miyabeana) as a Suitable Forage Material for Monogastric Herbivores in Zoos. [PDF]
J Anim Physiol Anim Nutr (Berl)ABSTRACT We assessed the suitability of a willow cultivar for monogastric herbivores in zoos using a rabbit model. Thirty‐six male New Zealand White × Californian rabbits at 5 weeks of age were provided with bark and leaf material from a willow cultivar, Salix miyabeana (SX61), in one of four treatments for 6 weeks: UC (unrestricted control of pelleted

Spermatophyta Molecular Clock: Time Drift and Recent Acceleration. [PDF]
Plant Environ InteractExponential increase in the base substitution rate in recent geologic time. ABSTRACT Angiospermae radiation is widely recognized as a mid‐Cretaceous event, but the adaptive radiation of Asarum and Viola as spring ephemerals also occurred during the Quaternary. To better understand the evolution of Angiospermae through geological time, a robust and well‐

Geologic environments for nuclear waste repositories
MATEC Web of Conferences, 2017 High-level radioactive waste (HLW) results from spent reactor fuel and reprocessed nuclear material. Since 1957 the scientific consensus is that deep geologic disposal constitutes the safest means for isolating HLW for long timescales.

Effect of reducing groundwater on the retardation of redox-sensitive radionuclides
Geochemical Transactions, 2008 Laboratory batch sorption experiments were used to investigate variations in the retardation behavior of redox-sensitive radionuclides. Water-rock compositions were designed to simulate subsurface conditions at the Nevada Test Site (NTS), where a suite ...

Cavity-based secondary mineralization in volcanic tuffs of Yucca Mountain, Nevada: a new type of the polymineral vadose speleothem, or a hydrothermal deposit? [PDF]
International Journal of Speleology, 2005 Secondary minerals (calcite, chalcedony, quartz, opal, fluorite, heulandite, strontianite) residing in open cavities in the Miocenerhyolite tuffs of Yucca Mountain, Nevada have been interpreted by some researchers as "speleothemic" formations, deposited ...
