Abstract Titanium (Ti) and its alloys as bio-implants have excellent biocompatibilities and osteogenic properties after modification of chemical composition and topography via various methods.The corrosion resistance of these modified materials is of great importance for changing oral system, while few researches have reported this point.Recently,
The heterogeneous oxidation of olefins to vicinal diols was investigated using an Os-Zn-Al hydrotalcite-like catalyst (HTlc).The Os-Zn-Al HTlc was synthesised by the co-precipitation method and characterised fully using XRD, Aluminum TIG Rod FT-IR, TEM, SEM, ICP-OES and BET surface area measurements.The ability of the synthesised Os-Zn-Al HTlc to c
A hybrid algorithm and regularization method are proposed, for the first time, to solve the one-dimensional degenerate inverse heat conduction problem to estimate the initial temperature distribution from point measurements.The evolution of the heat is given by a degenerate parabolic equation with singular potential.This problem can be formulated i
Infection with echinococcus has a world-wide distribution.This parasite hand pulse set affection almost all body organs (such as brain, lungs, spleen, billiary tract, liver, thyroid, parotid, tongue, bone, prostate, bladder, tonsile, pulmonary arteries and inferior vena cava).The other important body organ which also is infected by this parasite is
Based on the static analysis, dynamic model of C80 heavy haul train was built to investigate the influence of partial load on running safety of Brushes heavy haul train.Under the different partial load condition, the derailment coefficient and the wheel load reduction rate were calculated when the train passed the curve.The analysis results show th
