Gregarious settlement in barnacle larvae (cyprids) is induced by a contact pheromone, the settlement-inducing protein complex (SIPC). The SIPC has been identified both in the cuticle of adult barnacles and in the temporary adhesive secretion (footprint) of cyprids. Besides acting as a settlement inducer, the presence of the SIPC in footprints points to its additional involvement in the adhesion...

The barnacle Balanus ( = Amphibalanus) amphitrite is a major marine fouling animal. Understanding the molecular mechanism of larval settlement in this species is critical for anti-fouling research. In this study, we cloned one isoform of p38 MAPK (Bar-p38 MAPK) from this species, which shares the significant characteristic of containing a TGY motif with other species such as yeast, Drosophila a...

The pile–beam–arch method (PBA) is increasingly being used in the construction of metro stations with complex traffic conditions. rise–span ratio arch not only affects height station, but also rationality design subway and safety construction. mechanical response steel pipe piles different ratios effect controlled surface settlement have been investigated interactions involved pile–soil system....

The artificial freezing method can effectively improve the stability of strata and provide favorable conditions for construction safety shield tunnel in water-rich strata. Based on frozen tunneling project a metro station, which is close to important buildings, reasonable parameters are proposed this paper. simulation model was established by using Plaxis 3D finite element software (Version 201...

An automatic process for estimating ground stability and settlement of circular tunnels is developed practitioners in this paper using finite difference method FLAC code. The numerical model aims to simulate the movement relaxation soil around shield lining annulus that occurs due overcutting grouting tunnel void by a boring machine. To achieve this, uses pressure technique progressively reduce...
