abstract in aggregate, active forms of reactive silica with mineral names are sometimes associated with sand and gravel in concrete mixture. alkali hydroxides originated from alkalis in the cement or other resources form an alkaline silica gel with this reactive silica which becomes swallowed and expanded during time causing damage to concrete. there have been growing researches on alkaline r...

The endodermal cells of the shoot are thought to be the gravity-sensing cells in Arabidopsis. The amyloplasts in the endodermis that sediment in the direction of gravity may act as statoliths. Endodermis-specific expression of SGR2 and ZIG using the SCR promoter could complement the abnormal shoot gravitropism of the sgr2 and zig mutants, respectively. The abnormalities in amyloplast sedimentat...

An alternative description of the layer structure of SmC* devices is used to consider the cause for wide variations in the zig-zag defect density in such devices using the same alignment layer material. In this paper, we show how the topography of the surface layer due to imperfect coating techniques and materials promotes the formation of zig-zag defects. We show that if the alignment surface ...

Arabidopsis thaliana zigzag (zig) is a loss-of-function mutant of Qb-SNARE VTI11, which is involved in membrane trafficking between the trans-Golgi network and the vacuole. zig-1 exhibits abnormalities in shoot gravitropism and morphology. Here, we report that loss-of-function mutants of the retromer large subunit partially suppress the zig-1 phenotype. Moreover, we demonstrate that three paral...

Power-aware operating systems/processor controllers ensure that the system temperature does not exceed a threshold by utilizing system-throttling, where the clock speed is scaled to an equilibrium load. We denote this as the Constant policy, and compare against Zig-Zag policies that alternate between phases of cooling and heating. In this paper, we characterize and calculate the best possible Z...

2014 The magnetoelastic problem of a zig-zag 90° Bloch wall in iron is studied, either for a (110) or (001) wall. The elastic strains, due to magnetostriction, are calculated in both cases. The total energy of a zig-zag wall is obtained by adding, to the usual anisotropy and exchange contributions, the elastic term. Thus we find the equilibrium values for the periodicity and the angle of the zi...

The structure of single walled armchair and zig-zag carbon nanotubes having 70 atoms and two carbons replaced by boron or nitrogen is obtained at minium energy using HF/6-31G* molecular orbital theory. The calculations show that the ground state of the zig-zag tubes is a triplet state while for the armchair tubes it is a singlet. In the zig-zag tubes the density of states at the Fermi level is ...

The effect of defect complexes on the stability, structural and electronic properties of single-walled carbon nanotubes and boron nitride nanotubes is investigated using the ab initio pseudopotential density functional method implemented in the Castep code. We found more substantial atomic relaxations in the zig-zag carbon nanotube than the armchair one. We find that the B(C)B(c) defect introdu...

A convenient integral representation for zig-zag four-point and two-point planar Feynman diagrams relevant to the bi-scalar D-dimensional fishnet field theory is obtained. This gives a possibility evaluate exactly of series in special cases. In particular, we give fairly simple proof Broadhurst-Kreimer conjecture about values multi-loop which make significant contribution renormalization group ...
