An outstanding challenge in protein folding is understanding the origin of "internal friction" in folding dynamics, experimentally identified from the dependence of folding rates on solvent viscosity. A possible origin suggested by simulation is the crossing of local torsion barriers. However, it was unclear why internal friction varied from protein to protein or for different folding barriers ...

This study aims to analyze the groundwater flow changes caused by rainfall and its influence on slope stability. Taking in Dingjiafen, Chuxiong, Yunnan, China as area, monitored data of drew upon calculation module ArcGIS predict change water level fluctuation soil. In this way, visual simulation distribution was realized; seepage slope’s stability also analyzed. The results indicate that: (1) ...

In order to study the strength characteristics of alluvial silt in lower Yellow River Channel at Luokou, Jinan, by varying moisture content five times, direct shear tests were conducted and soil–water curves obtained explore relationships between matric suction as well bishop coefficient strength. The curve test shows that water retention samples can be fitted VG (Van Genuchten) model with appr...

The applications and studies of gravity anchors in the ocean are becoming more extensive. Most research, however, has been directed toward bearing properties sand. Relatively less attention paid to clay. Clay is widely distributed on seabed. research capacity clay great significance for offshore oil exploitation. Therefore, anchor was investigated by conducting reduced-scale model tests, proces...

Railways are one of the largest transportation networks in world. One key subgrade problems railway track is associated with progressive shear failure (PSF). To-date, limited number studies have addressed mechanism PSF, especially extending mechanics unsaturated soils. In this paper, PSF studied aid computer program that was developed using a Visual Basic AutoCAD, Mohr-Coulomb criteria within s...

Adding a type of municipal solid waste (incinerator slag) into ultrafine tailings can effectively enhance the mechanical properties tailings. With an aim to study macro- and micro-mechanical slag mixture (TSM), strength parameters (internal friction angle, cohesion) with different contents were analyzed by geotechnical experiments particle flow simulations, respectively. The macroscale experime...

In order to study the influence of creep soft soil and corrosion damage reinforced concrete on horizontal bearing behavior piles, novel p-y curve model was established considering time-varying characteristics parameters. The attenuation law bending stiffness piles under chloride erosion analyzed by introducing reduction factor. limit state function pile reliability analysis then characteristics...

Introduction: Although the theory of Roche [1] for the tidal disruption limits of orbiting satellites assumes a fluid body, a length to diameter of exactly 2.07:1, and a particular body orientation, the theory is commonly applied to the satellites of the solar system and to small asteroids and comets passing nearby a planet. Clearly these bodies are neither fluid nor generally that elongated, s...
