No disks around low-mass stars and brown dwarfs in the young sigma Orionis cluster? [PDF]
, 2001 We report on the analysis of 2MASS near-infrared data of a sample of low-mass stars and brown dwarfs in the sigma Orionis cluster. Youth and cluster membership have been spectroscopically confirmed using the Li I spectral line. We find little evidence in

Effect of Hairiness on Fabric Colour Characteristics [PDF]
Tekstilec, 2020 Designing the colour appearance of textiles requires taking into account their surface properties, hairiness among others. The villi protruding on the surface not only affect the quality of textile dyeing, but also largely determine its optical ...

Analysis of pathogenic bacteria using exogenous volatile organic compound metabolites and optical sensor detection [PDF]
, 2015 A novel, low-cost and simple method for the detection of pathogenic bacteria is proposed. The approach is based on the generation of an exogenous volatile organic compound (VOC) produced by the addition of an enzyme substrate to the bacterial sample. The

Colour analysis of degraded parchment [PDF]
, 2013 Multispectral imaging was employed to collect data on the degradation of an 18th century parchment by a series of physical and chemical treatments. Each sample was photographed before and after treatment by a monochrome digital camera with 21 narrow-band
