Abstract Cutting fluid is crucial in ensuring surface quality and machining accuracy during machining. However, traditional mineral oil-based cutting fluids no longer meet modern machining’s health environmental protection requirements. As a renewable, pollution-free alternative with excellent processing characteristics, vegetable oil has become an inevitable replacement. lacks oxidation stability, extreme pressure, antiwear properties, which are essential for The physicochemical...
Abstract Micro-grinding with a spherical grinding head has been deemed an indispensable method in high-risk surgeries, such as neurosurgery and spine surgery, where bone long plagued by the technical bottleneck of mechanical stress-induced crack damage. In response to this challenge, ultrasound-assisted biological micro-grinding novel process proposed researchers. Force modeling is prerequisite for parameter determination orthopedic difficulty establishing accurately predicting force...
Minimizing the negative effects of manufacturing process on environment, employees, and costs while maintaining machining accuracy has long been a pursuit industry. Currently, nanofluid minimum quantity lubrication (NMQL) used in cutting grinding studied as useful technique for enhancing machinability empowering sustainability. Previous reviews have concluded beneficial NMQL factors affecting them, including volume fraction nanoparticle species. Nevertheless, summary mechanism performance...
Nitrogen (N) loss rates were determined in permeable sediments of the Wadden Sea using a combination stable N isotope incubation experiments and model simulation approaches during three seasons. Three different methods that employed pairing technique used: intact core incubations simulating either (1) diffusive or (2) advective transport conditions (3) slurry incubations. from under simulated exceeded those measured by 1–2 orders magnitude, but comparable to observed generally showed little...
Abstract Eddy correlation (EC) measurements in the benthic boundary layer (BBL) allow estimating O 2 uptake from a point distant to sediment surface. This noninvasive approach has clear advantages as it does not disturb natural hydrodynamic conditions, integrates flux over large foot‐print area and allows many repetitive measurements. A drawback is, however, that measured bottom water is necessarily equal across sediment‐water interface. fundamental assumption of EC technique mean current...
Abstract. In natural coastal wetlands, high supplies of marine sulfate suppress methanogenesis. Coastal wetlands are, however, often subject to disturbance by diking and drainage for agricultural use can turn potent methane sources when rewetted remediation. This suggests that preceding land measures suspend the sulfate-related suppressing mechanisms. Here, we unravel hydrological relocation biogeochemical S C transformation processes induced emissions in a disturbed peatland despite former...
Within Kirkwood theory, we study the translational diffusion coefficient of a single polymer chain in dilute solution, and focus on small difference between short-time value D(K) asymptotic long-time D. We calculate this correction term by highly accurate large-scale Brownian dynamics simulations, show that it is perfect agreement with rigorous variational result D<D(K), Fixman’s Green–Kubo formula, which re-derived. This resolves puzzle posed earlier numerical results [Rey et al.,...
The coupling of subseafloor microbial life to oceanographic and atmospheric conditions is poorly understood. We examined diagenetic imprints lipid biomarkers past activity evaluate its response glacial-interglacial cycles in a sedimentary section drilled on the Peruvian shelf (Ocean Drilling Program Leg 201, Site 1229). Multiple distinct layers barite dolomite, i.e., minerals that typically form at sulfate-methane transition (SMT), occur much shallower burial depth than present SMT around 30...
A numerical reaction-transport model was developed to simulate the effects of microbial activity and mineral reactions on composition porewater in a 230-m-thick Pleistocene interval drilled Peru-Chile Trench (Ocean Drilling Program, Site 1230). This site has profiles similar those along many continental margins, where intense methanogenesis occurs alkalinity surpasses 100 mmol/L. Simulations show that sulphate reduction, anaerobic oxidation methane, ammonium release from organic matter...
