Evidence of Climatic Effects in the Annual Rings of Trees
Ecology, 1920The first substantial comparison between rings and rain with which the author is acquainted was made by the astronomer, J. C. Kapteyn of Holland, in i88o and i88i on oaks in the Rhine region. Professor Kapteyn has recently prepared and published a brief pamphlet on the subject.2 A similar comparison between the growth of the great sequoia (Sequoia ...

Distribution and Speciation of Metals in Annual Rings of Black Willow
Journal of Environmental Quality, 2005ABSTRACTInformation on the spatial distribution and speciation of metals in nonhyperaccumulator plants is lacking. This study used synchrotron X‐ray fluorescence (SXRF) compositional imaging to investigate the spatial distribution of Ni, Mn, Cu, Zn, and Fe in annual rings of black willow (Salix nigra L.) collected from a metal‐contaminated area, and ...

Enhancement of annual rings on industrial CT images of logs
Object recognition supported by user interaction for service robots, 2003Many researchers have shown the ability of X-ray computer tomography (CT) of acquiring knowledge about the internal structure of logs. Contrarily to medical CT scanners, industrial CT scanners should satisfy more extreme constraints (in terms of speed, duty cycle, radiation safety, reconstruction circle and aperture size) in order to be used in a ...
