Abstract The influence of block forms on the shear behaviour soil–rock mixtures with soft blocks (soft S–RMs) can be efficiently investigated by discrete element method (DEM) basis accurate 3D models accounting for breakage. This paper proposes a novel modelling approach, based spherical harmonics series, generation geometries different but same convexity and angularity. An already existing non...

According to the level of measurement scale, friction force changes its nature and is determined by different depend-encies. The paper views a procedure for determining molecular component based on evaluation specif-ic shearing resistance links un-der elastic interaction silicon nitride cantilever needle having steel sample, used scanning section sample surface in nanometer range with an atomic...

The development of tensile stress can cause desiccation cracks, further increasing infiltration and inducing instability in green infrastructure (slopes landfill liners). Recent research has promoted the use biochar (i.e., stable carbon with a life period more than 500 years) as an eco-friendly material that provide simultaneous benefits reducing stresses crack development, aiming to enhance co...

Abstract Nut shape is an important trait in determining the value of a pecan ( Carya illinoensis ) nut crop. influences attractiveness to consumers, filling, ease mechanical cracking, and distinctive enough that it primary means cultivar identification. Narrow sense heritability (h 2 fraction phenotypic variance attributed variation genes with additive effect. Estimation h key breeding programs...

Introduction: We have completed analysis of a new near-field rock count at the Mars Pathfinder landing site and determined that the previously published [1,2] rock count suggesting 16 % cumulative fractional area (CFA) covered by rocks is incorrect. The earlier value is not so much wrong (our new CFA is 20%), as right for the wrong reason: both the old and the new CFA’s are consistent with remo...

Residual gas saturation is one of the most important parameter in determining recovery factor of water-drive gas reservoir. Visual observation of processes occurring at the pore level in micromodels can give an insight to fluid displacements at the larger scale and also help the interpretation of production performance at reservoir scale. In this study experimental tests in a glass micromod...

Background: Although, different grafts are used for nasal tip plasty in cases with under projected or ill defined tip, the selection of a graft material, which provides sufficient amount of tissue with least donor site morbidity and low recipient site complication is challenging. The objectives of the present study were to examine the usefulness of cartilaginous dorsum as a proper material for ...

Binational genetic evaluation between Germany and France were performed for each type trait using a single-trait MACE (multiple across-country evaluation) model. Daughter yield deviations (DYD) of bulls having 30 equivalent daughter contributions or more were the data for parameter estimation. Full pedigree information of bulls was used via sire and dam relationships. In general, across-country...

• RCA with high CMC value, complex shape and surface leads to worse interfacial adhesion failure. GA-BP artificial neural network presented considerable capacity predict the damage behavior. The cement mortar content exhibited greatest influence on property of asphalt mortar-RCA interface. Asphalt-aggregate interface’s properties commonly affect initiation evolution within concrete materials, r...
