In this work, the Liquid Impingement Erosion (LIE) performances of deep-rolling (DR) treated and non-treated Ti64 were investigated. Various erosion stages, from the incubation to the terminal erosion stages, could be observed. A full factorial design of experiments was used to study the effect of DR process parameters (Feed Rate, Spindle Velocity, Number of Passes, Pressure) on the residual st...

Sediment yield is a key factor in river basins management due to the various and adverse consequences that erosion and sediment transport in rivers may have on the environment. Although various contributions can be found in the literature about sediment yield modeling and bank erosion monitoring, the link between weather conditions, river flow rate and bank erosion remains scarcely known. Thus,...

The decision of where, when, and how to apply the most effective postfire erosion mitigation treatments requires land managers to assess the risk of damaging runoff and erosion events occurring after a fire. To meet this challenge, the Erosion Risk Management Tool (ERMiT) was developed. ERMiT is a web-based application that uses the Water Erosion Prediction Project (WEPP) technology to estimate...

The evaporation of inertial confinement fusion first wall materials from unattenuated pellet X-rays and from radiation emitted by a cavit.y buffer qas is examined. The low vapor pressure and low X-ray attenuation coefficient of carbon give it a lower erosion rate than stainless steel, despite the larger thermal conductivity of Type 316 stainless steel. For the argon buffer gas containing 0.2% N...

The aim of this study was to investigate whether the accelerated replicative senescence seen in Werner syndrome (WS) fibroblasts is due to accelerated telomere loss per cell division. Using single telomere length analysis (STELA) we show that the mean rate of telomere shortening in WS bulk cultures ranges between that of normal fibroblasts [99 bp/population doubling (PD)] and four times that of...

Background: Bone erosion is a common manifestation of sinus fungus ball (SFB) on CT imaging, however, the relationship between CT imaging and clinical features of SFB with bone erosion were not clear. Purpose: To evaluate the CT imaging and clinical features of sinus fungus ball with bone erosion and to explore the possible factors underlying its formation. Material and methods: The clinical da...

As elicitors of terrestrial system change (e.g., land use transformation) through the introduction of anthropogenic causes, the spatial patterns and levels of roads might be more detrimental to the long-term health of ecosystems at a large scale than the road paving itself. This paper reveals the relationship between soil erosion and roads from a large-scale perspective in Jiangxi Province, Chi...

We report on numerical simulations of acid erosion in a fractured specimen of Carrara marble. The simulations combine two recent advances in lattice-Boltzmann methodology to accurately and efficiently calculate the velocity field in the pore space. A tracer diffusion algorithm was then used to calculate the distribution of reactants in the fracture, and the local erosion rate was obtained from ...
