In this work, a novel method is put forward to quantitatively simulate the subsurface damages microstructural alteration of titanium alloy components subjected to microscale cutting. A trans-scale numerical framework is conducted with the purpose of revealing the underlying influence mechanism of tool structure parameters on subsurface dislocation configurations using a dislocation dynamics-bas...

Reactions associated with the geochemical process of serpentinization can generate copious quantities of hydrogen and low-molecular-weight organic carbon compounds, which may provide energy and nutrients to sustain subsurface microbial communities independently of the photosynthetically supported surface biosphere. Previous microbial ecology studies have tested this hypothesis in deep sea hydro...

Predictions in subsurface formations consists of two steps: characterization and prediction using the characterization. In the characterization, we reconstruct the subsurface properties, such as distributions of permeability and porosity, with a set of limited data. A Bayesian approach using Markov Chain Monte Carlo (MCMC) methods is well suited for reconstructing permeability and porosity fiel...

In this paper, we investigate the penetration capabilities of microwaves, particularly at L-band, for the mapping of subsurface heterogeneities such as lithology variations, moisture or sedimentary structures. The experiment site, the Pyla Dune, is a bare sandy area allowing high signal penetration and presenting large subsurface structures (paleosoils) at varying depths. Several radar data set...

In this paper, details of a conjunctive surface–subsurface numerical model for the simulation of overland flow are presented. In this model, the complete onedimensional Saint-Venant equations for the surface flow are solved by a simple, explicit, essentially non-oscillating (ENO) scheme. The two-dimensional Richards equation in the mixed form for the subsurface flow is solved using an efficient...

The OBJECTIVE was to demonstrate an original minimally invasive way restore the continuity of lobar duct after its complete intersection. METHODS AND MATERIALS. study included 3 patients aged 38, 56 and 69 years who underwent laparoscopic cholecystectomy for cholelithiasis, cholecystolithiasis in various medical institutions city. In all patients, intersection right with formation external bili...

Plecoptera, an environmentally sensitive order of aquatic insects commonly used in water quality monitoring is experiencing decline across the globe. This study addresses landscape factors that impact species richness stoneflies using US Geological Survey Hierarchical Unit Code 8 drainage scale (HUC8) state Indiana. Over 6300 specimen records from regional museums, literature, and recent effort...

Population level response to hypoxia has become an issue of global significance because of increased frequency and intensity of hypoxic events worldwide, and the potential for global warming to exacerbate hypoxic stress. In this study, we sequenced two nuclear intronic regions and a single mitochondrial region across seven populations of the African cyprinid, Barbus neumayeri from two river dra...

It is well appreciated that historical and ecological processes are important determinates of freshwater biogeographic assemblages. Phylogeography can potentially lend important insights into the relative contribution of historical processes in biogeography. However, the extent that phylogeography reflects historical patterns of drainage connection may depend in large part on the dispersal capa...
