Talin is an adaptor protein that couples integrins to F-actin. Structural studies show that the N-terminal talin head contains an atypical FERM domain, whereas the N- and C-terminal parts of the talin rod include a series of α-helical bundles. However, determining the structure of the central part of the rod has proved problematic. Residues 1359-1659 are homologous to the MESDc1 gene product, a...

Axial and lateral pressure loss in a 5 × rod–bundle with split-type mixing vane spacer grid was experimentally measured using differential transmitters at different sub-channel Reynolds numbers (Re) orienting angles. The geometrical parameters of the 5–rod bundle are as follows: they have same diameter (D = 9.5 mm) pitch ( p 12.6 those real fuel rods typical pressurized water reactor (PWR), hyd...

Abstract The fuel shape and flow path structure of the plate-type reactor are different from those conventional rod-bundle reactor, which leads to difference between thermal-hydraulic phenomenon thermal conduction in rod bundle assembly. Therefore, this thesis, subchannel analysis model code applied developed. calculation results compared with simulation FLUENT MATRA experimental heat transfer ...
