Risk Factors for Seroreactivity Among Veterinary Workers in the Pacific Northwest.

Exposure to zoonotic diseases is a significant occupational risk in veterinary medicine. In this study, we characterized personal protective equipment use, injury frequency, and seroreactivity in Washington State veterinary workers. Using a risk matrix developed to reflect occupational risk factors for exposure to and multiple logistic regression, we explored determinants of risk for seroreactivity.

A light-fuelled nanoratchet shifts a coupled chemical equilibrium.

Biological molecular machines enable chemical transformations, assembly, replication and motility, but most distinctively drive chemical systems out of-equilibrium to sustain life. In such processes, nanometre-sized machines produce molecular energy carriers by driving endergonic equilibrium reactions. However, transforming the work performed by artificial nanomachines into chemical energy remains highly challenging.

Particulate matter emissions during field application of poultry manure - The influence of moisture content and treatment.

Along with industry and transportation, agriculture is one of the main sources of primary particulate matter (PM) emissions worldwide. Bioaerosol formation and PM release during livestock manure field application and the associated threats to environmental and human health are rarely investigated. In the temperate climate zone, field fertilization with manure seasonally contributes to local PM air pollution regularly twice per year (spring and autumn).
