Background and aims Respiratory diseases are one of the more Prevalence occupational diseases in colour Production industries. Because chemical hazard that are present in such industries improving screening methods is essential. There is some kind of respiratory function evaluation methods it seems that serial peak flowmetry has found a new place. MethodS In this cross sectional study...
Colour labeling is critical to the real-time performance of colour-based vision systems and is used for low-level vision by most RoboCup 2002 physically based teams. Unfortunately, colour labeling is sensitive to changes in illumination and manual calibration is both time consuming and error prone. In this paper, we present KADC, a robust method for Knowledge-based Autonomous Dynamic Colour Cal...
reveals " blue " bias for colour constancy in real and simulated scenes. On calculating metamer sets for spectrally tunable LED illuminators. Are colour constancy mechanisms biased for typical illuminations? AIC 2013. Abstract The light reflected from object surfaces changes with the spectral content of the illumination. Despite these changes, the human visual system tends to keep the colours o...
BACKGROUND AND AIMS Speciation in angiosperms can be accompanied by changes in floral colour that may influence pollinator preference and reproductive isolation. This study investigates whether changes in floral colour can accompany polyploid and homoploid hybridization, important processes in angiosperm evolution. METHODS Spectral reflectance of corolla tissue was examined for 60 Nicotiana (...
Animals from a wide range of taxonomic groups are capable of colour change, of which camouflage is one of the main functions. A considerable amount of past work on this subject has investigated species capable of extremely rapid colour change (in seconds). However, relatively slow colour change (over hours, days, weeks and months), as well as changes arising via developmental plasticity are pro...
The authors investigated the extent to which a change to an object’s colour is overtly prioritized for fixation relative to the appearance of a new object during real-world scene viewing. Both types of scene change captured gaze (and attention) when introduced during a fixation, although colour changes captured attention less often than new objects. Neither of these scene changes captured atten...
Characterization and the antibacterial potential of gold (AuNPs) and silver nanoparticle (SNPs) biosynthesized greenly using exopolysaccharides (EPS) and Culture Free Supernatant (CFS) of Wesiella confusa against some multidrug resistance (MDR) E. coli was investigated. The biosynthesized nanoparticles were characterized by UV-visible spectra, Fourier Transfor...
Background and Objective: This study was aimed to evaluate the collagen fibers qualitatively and its correlation with microvascular density in various grades of oral submucous fibrosis (OSMF). Material and Methods: The present study comprised of total 40 cases of oral submucous fibrosis. Picrosirius red staining was done on all the specimens’ sections. ...
