Improvement on bacteria-induced calcium mineralization ability of Bacillus pseudofirmus by an integrated high-throughput screening strategy

The CaCO3-mineralizing bacteria from different taxonomic groups have shown potential in restoration of construction material such as concretes, cements and stony materials. However, these strains are far from the demand of practical application due to some shortages, including the low mineralizing capacity. In this work, an integrated high...

Influences of characteristic size of contact bodies on rolling contact

The rolling contact of elastic bodies (upper body and lower body) can be analyzed with the Hertz theory and the Kalker’s model. It is generally believed that the width of the contact area should be much smaller than the characteristic size of each elastic body, to ensure that the half-space assumption is valid. However the definition of “much...

Residual fatigue life evaluation of rail at squats seeds using 3D explicit finite element analysis

A modeling procedure to predict the residual fatigue life of rail at squats seeds is developed in this article. Two models are involved: a 3D explicit Finite Element (FE) model to compute the stress and strain at squats in rail, and the J-S fatigue damage model to determine the residual fatigue life on the basis of the computed stress and strain...

Interconnecting Urban Planning with Multi-Scale Urban Quality: Review of Macro Scale Urban Redevelopment Project on Micro Scale Urban Quality in Shenzhen

The Shenzhen planning system has been effective in promoting economic growth through the prodigious urbanization of land. It has given priority to the ‘macro-level’ planning goals of economic growth through physical development. Questions can be raised about the physical and social outcomes from the development process at the ‘micro-level’, not...
