However, the HOS-2 and HOS-3 values in FT semen had high correlations with NRR (r = 0.65, r = 0.66, P < 0.001 at batch level and r = 0.63, r = 0.71, P < 0.01 at bull level), which was comparable t...
Wood is a hygroscopic material that is affected by shape changes. The aim of this study was to analyse the variability of wood swelling in the individual anatomic directions. Wood swelling was examine...
The relation between the swelling of graft union and trunk girth or shear strength at graft union was investigated. The trunk girth of trees grafted onto JM7 was largest and the coefficient of varianc...
The objective of this study was to determine the volumetric swelling and shrinkage characteristics of air-dried Corsican pine in the longitudinal, tangential and radial directions. For this purpose, t...
A relationship between the planar and spatial tortuosities of a statistically isotropic crack network in a clay soil is derived from the fact that connected cracks outline peds and are their boundarie...
A model is presented for prediction of crack network geometry in clay soils. The starting point is the similarity between a crack network in rocks and that in soils, and, hence, principles of multiple...
The capping and remediation of municipal landfills require large amounts of soil material which should fulfil definite requirements with respect to hydraulic and shrinkage properties. One of such mate...
Strength regain in aggregate beds as a consequence of wetting and drying cycles was studied in two Andisols and one Mollisol from Chile, collected at two depths (0-10 and 40-60 cm). In the Mollisol, ...
The aim of this study was to investigate the soil volume changes for moorsh, willow and moss peat layers during drying-wetting cycles. The measurements of soil volume changes were made using the ‘sara...
