10+ hour, 38+ min ago   (347+ words) The delineation of mineralized zones within deposits is inherently associated with geological uncertainty, directly impacting resource-reserve estimation and eventual extraction. This study presents a comparative analysis of three geological modeling techniques, including Indicator Kriging (IK), Nearest Neighbor (NN), and Multilayer…...

11+ hour, 33+ min ago   (409+ words) Wall thinning caused by corrosion changes the circumferential strain response of storage tanks, but nonlinear coupling among structural parameters, loading conditions, strain characteristics, and defect geometry makes direct inversion difficult. This paper develops a strain-based, finite element (FE)-based machine…...

11+ hour, 50+ min ago   (495+ words) Steel storage tanks are erected on site by multi-cylinder hydraulic lifting, conventionally from one power unit feeding all cylinders through a flow divider. Decentralized alternatives have not been evaluated for this task, and modularity in fluid power is rarely quantified....

13+ hour, 37+ min ago   (543+ words) The Northeastern Donkey represents an important animal genetic resource adapted to the semi-arid conditions of Brazil, being recognized for its hardiness and ability to survive under challenging environmental conditions. However, the progressive reduction in the use of these animals in…...

14+ hour, 25+ min ago   (443+ words) Spearmint is a medicinal and aromatic crop vulnerable to several diseases, and its cultivation relies heavily on chemical inputs, which can alter phytonutrient quality and raise environmental and health concerns. To address this, the current study focused on developing a…...

14+ hour, 58+ min ago   (596+ words) Multi-station global navigation satellite system (GNSS) displacement-residual forecasting may benefit from neighbouring stations, yet unrestricted spatial aggregation can obscure station-local temporal dynamics and the independent value of spatial information. Whether neighbouring stations provide additional predictive information after a strong station-local…...

14+ hour, 58+ min ago   (447+ words) Post-activation performance enhancement (PAPE) is often attributed to elevated neural drive, yet neuromuscular and mechanical responses are rarely tracked concurrently. This study examined whether the two scale proportionally over the 1–4 min following a conditioning activity, with a maximal countermovement jump…...

15+ hour, 11+ min ago   (296+ words) Museums face a conflict between energy-efficient gallery lighting and protecting light-sensitive collections from photochemical damage: increasing the luminous efficacy of white LEDs requires shifting spectral power toward the high-energy blue band, accelerating degradation of organic materials. Prior work treated these…...

15+ hour, 36+ min ago   (591+ words) During the frequent charging, discharging, and storage processes of underground compressed air energy storage systems, the damage and degradation of sealing plugs directly affect the long-term stability of gas storage caverns. Using a self-developed cyclic charging–storage–discharging–restorage gas…...

15+ hour, 58+ min ago   (421+ words) Proton-exchange membrane fuel cell degradation is one of the factors that limit the deployment of this technology in the automotive market. Accelerated Stress Tests (ASTs) are the standard tool for assessing durability during design and development phases, thanks to their…...
