Improvements in the sustainability of industrial hemp plantations by remote sensing and modelling of agro-biochemical parameters
(2024-06-13)
Research report
Open AccessRecent technological advances allow remote sensing (RS) to be applied affordably to extensive crops, improving agriculture efficiency and sustainability. In precision agriculture, multispectral imaging (MI) is used to apply ... -
Framboidal and spherulitic pyrite in sediment-hosted ore deposits of Iran
(2024)
Article
Open AccessFramboidal pyrite is common in marine sediments and organic matter-bearing sedimentary rocks. It has also been reported in many ‘sediment-hosted ore deposits’, such as shale-hosted massive sulfide (SHMS) or clastic-dominated ... -
Strongly different adhesion reduction for 1D or 2D random fractal roughness, and an extension of the BAM model to anisotropic surfaces
(2024-09-19)
Article
Open AccessThe infuence of roughness on adhesion has been studied since the time of Fuller and Tabor, but recently there has been debate about how roughness exactly seems to kill (but sometimes enhance!) adhesion, particularly with ... -
Evaluating the impact of rail surface roughness post-grinding: an experimental and elastoplastic modelling approach
(2025-01-01)
Article
Open AccessGrinding is regularly conducted on railway tracks to prevent crack propagation and surface deterioration. However, grinding can introduce roughness on rail surfaces, potentially leading to stress and strain concentration ... -
Neural network approaches for leakage flow quantification in masonry dam
(2024-10-22)
Article
Restricted access - publisher's policyHistorically, one of the most common causes of dam failure has been overtopping, primarily in earthfill dam, accounting for approximately 34% in the United States, according to the Association of State Dam Safety Officials. ... -
Roughness induced variation as a new mechanism for hydrodynamic lubrication between parallel surfaces
(2024-10-09)
Article
Open AccessThis work proposes a new lift mechanism capable of explaining the hydrodynamic lift observed in real mechanical face seals with parallel surfaces. While it is well established that roughness is a key factor inducing such ... -
Uso de redes neuronales en la detección de filtraciones en el cuerpo de las presas de mamposteria
(Comité Nacional Español de Grandes Presas (SPANCOLD), 2024)
Conference report
Restricted access - publisher's policyHistóricamente, una de las causas más comunes de rotura de las presas, principalmente en presas de materiales sueltos, se debe a vertido por coronación, alrededor del 34% en EEUU, según la Association of State Dam Safety ... -
Modeling copper leaching from non-pulverized printed circuit boards at high concentrations of bioregenerated ferric sulfate
(2024-10-01)
Article
Open AccessThis work studies the leaching of copper contained in waste printed circuit boards (PCB) with ferric sulfate, with the aim of improving the results found in the literature for an industrial application of the process. For ... -
Analysis of the mining equipment replacement time. A case study focused on drilling rig
(Elsevier, 2024-10-10)
Article
Open AccessMining equipment is subjected to degradation throughout its operation lifetime, being the definition of the replacement time for mining equipment a vital question. Requiring accurate information about the performance of ... -
Improving the transfer of dissolved oxygen in a biological Fe2+ oxidation process using a venturi jet as an intensive aeration system
(Elsevier, 2024-07-31)
Article
Restricted access - publisher's policyThe low bio-production of Fe3+ as a leaching agent is one of the main limitations to implementing industrial bio-processes at feasibility conditions. The main limitation of the bio-oxidation process of Fe2+ is the low ... -
Analysis of physical properties of coarse aggregates recovered from demolished concrete with a two-stage water jigs process for reuse as aggregates in concrete
(Multidisciplinary Digital Publishing Institute (MDPI), 2024-07-19)
Article
Open AccessThe present work analyses the physical characteristics of aggregates recovered with the waterjigging process from comminuted concrete. In this work, conventional concrete (C16/20) was crushed to a top size of 20 mm with a ...
