A simplified analytical solution for steel plate strengthened circular tunnel concrete linings is presented, considering various interface slip modes. The full derivation the introduced in detail, from which explicit expressions stress and displacement fields throughout system are obtained. distribution of lining deformation, internal force, interaction between were investigated by tunnel-steel...

Recent experiments have shown that flux through the fusion pore is sensitive to manipulations of the side-chain size of certain residues in the syntaxin (syx) membrane anchor. These residues were proposed to line the wall of the fusion pore of Ca(2+)-triggered exocytosis. Here we continued this line of experimentation to examine possible electrostatic interactions between the pore lining residu...

Abstract Stability of large underground structures depends on not only rock mass conditions but also excavation stages and support systems. In addition, complexity geological interaction with in situ affect the performance design. The Akyazı tunnel (Trabzon, Turkey) is 2478 m long was designed as 3 lanes double tubes, number at junction part increases to 5. Tunnel cross-sectional area from reac...

there are several methods for analysing the behaviour of underground structures under different loading conditions. most of these methods have many simplifications; therefore, in some cases, the results are too conservative and a very high safety factor, usually of more than 2 is needed. on the other hand, for stability analysis and the designing of support systems, these methods consider segme...

concrete is the most common material used to line irrigation canals and must maintain its durability for the lifetime of the canal. compressive strength has been used as an index to control the quality of concrete; concrete that remains durable under freeze-thaw conditions is that with high compressive strength. research has shown that concrete linings can show suitable compressive strength in ...

  The distribution and localization of acid and neutral mucins in various cells lining the olfactory epithelium of Cyprinus carpio have been studied histochemically by employing the PAS-AB technique. Variations in the localization of protein in different cells lining the olfactory epithelium have been correlated with the functional significance of the region concerned. Intense localization of t...

An increasing demand for improving neuronal imaging technologies in spatial-temporal resolution has emphasized in literature. Here we report a nanostructured memrisor/memcapacitor device is able to biocommunicate with the brain cancer cells without using tracers, antibodies and reagent. A “normal neuron” with a biomimetic acetylcholinesterase (ACHE) active gorge was made by cross-linked multipl...
