The increasing price and diminishing reserves of construction sand encourage a need to develop its sustainable cost-effective replacement, helping the transition towards circular economy. Waste glass is derivative natural could potentially show similar geotechnical behaviour. Using crushed waste (CWG) as an alternative traditional would offer double-duty benefit by address geo-environmental cha...

• Smooth and irregular particles have different wetting behaviour when hydrophobic. Sharp particle edges produce increasing apparent contact angles with drop volume. Concave convex liquid bridges can co-exist between hydrophobic particles. Liquid form over micron-scale distances particle. Attraction repulsion occur on bridge formation. Hydrophobic soils, which naturally in arid regions or after...

Introduction: In the search for life on Mars, investigating fluvial deposits will be a high priority for future landers. Although there is abundant evidence that fluvial processes worked with great intensity in the past (e.g., outflow channels, valley networks, and modified impact craters), aeolian processes dominate under the current environmental conditions. In fact there is evidence that ext...

The objective of this study was to estimate genetic parameters predicted N use efficiency (PNUE) and losses (PNL) as proxies loss for Holstein cows. Furthermore, we have assessed approximate correlations between PNUE, PNL, dairy production, health, longevity, conformation traits. These traits are considered important in many countries currently evaluated by the International Bull Evaluation Ser...

Keywords: Rockfill creep Particle mechanics method Water weakening Wetting–drying cycles Particle breakage Abrasion a b s t r a c t Rockfill is an important construction material for infrastructure engineering, such as dams, railways and airport foundations, which display a long-term post-construction settlement. However, the main mechanisms for rockfill creep and weathering influence still rem...

The objective of this study was to investigate genetic merit of return over feed (ROF), which is a herd profit index defined by CanWest Dairy Herd Improvement as a difference between milk income and feed cost. A multiple-trait (MT) model and random regression model (RRM) were used. The traits analyzed in MT were rearing cost and ROF of the first three lactations. In RRM, a cumulative ROF was fi...

Ballast, typically comprising large sized aggregate particles with uniform gradation, is an essential layer in the railroad track substructure. Functions of ballast include facilitating load distribution and drainage, maintaining track geometry and track stability, and providing track resilience and noise absorption. Throughout its service life, ballast goes through changes in gradation and par...

Background. Much of the sedimentary transport and depositional history of Mars may be recorded in the morphologic characteristics of the individual rocks or particles that make up its sedimentary clast population (defined as a rock fragment or grain resulting from the breakdown of larger rocks or bedrock). Measuring morphology is crucial; it retains the best record of sorting and abrasive effec...

Pressure on the coastline is escalating due to impacts of climate change, this leading a rise in sea-levels and intensifying storminess. Consequently, many regions coast are at increased risk erosion flooding. Therefore coastal protection schemes will increase cost scale. In response there growing use nature-based which aim be sustainable, effective adaptable. An example solution dynamic cobble...
