Design of a multispectral plenoptic camera and its application for pyrometry.

A multispectral imaging system, based on a modified plenoptic camera, is presented. By adding a color filter in the aperture plane of the imaging system, it is possible to simultaneously image multiple discrete colors of light-seven in this design. To develop a measurement system that does not rely on in situ calibrations, each of the optical elements was characterized a priori.

Novel insights into serodiagnosis and epidemiology of Erysipelothrix rhusiopathiae, a newly recognized pathogen in muskoxen (Ovibos moschatus).

Background: Muskoxen are a key species of Arctic ecosystems and are important for food security and socio-economic well-being of many Indigenous communities in the Arctic and Subarctic. Between 2009 and 2014, the bacterium Erysipelothrix rhusiopathiae was isolated for the first time in this species in association with multiple mortality events in Canada and Alaska, raising questions regarding the spatiotemporal occurrence of the pathogen and its potential impact on muskox populations.

Materials And Methods: We adapted a commercial porcine E.

Survey of pathogenic bacteria of biofilms in a metropolitan drinking water distribution system.

Bacteria, especially pathogenic bacteria, were detected in order to estimate the safety of drinking water distribution systems (DWDSs). Sixteen biofilms and 12 water samples (six retained and six flowing) were collected from a city DWDS in eastern China. Biofilms were observed using scanning electron microscopy.
