This paper presents a plastic mechanism analysis for circular hollow section (CHS) tubes strengthened using carbon fiber reinforced polymer (CFRP) deforming in an axi-symmetric (elephant foot) collapse mode under large deformation axial loading.The collapse proceeded progressively by folding about three concentrated hinge lines and hoop extension A
Glomalin is a glycoprotein identified in and extracted from cell walls of hyphae and spores of Glomeral fungi.It deposites on soil particles and acts as a glue which leads Toners to the formation and stabilization of soil aggregates.Water deficit stress by affecting mycorrizal symbiosis can alter glomalin production.This study was conducted as a fa
With global climate change, atmospheric nitrogen (N) deposition and drought have been well documented to cause substantial challenges for tropical and subtropical evergreen broad-leaved forests.Here, we conducted an experiment that measured the physiological responses of the seedlings of three dominant tree species (Tabebuia chrysantha, Elaeocarpus
A simple model was developed to describe the dependence Rocking of net CO2 exchange in a sphagnum peat bog as a function of incoming solar radiation, air temperature, and soil moisture.It was parameterized using the field measurement data from two neighboring sites in an undisturbed peat bog (the pine mire with shrub and sphagnum and the shrub-spha
