In the title compound, C(12)H(12)N(6)·4H(2)O, the two triazole rings adopt a cis configuration with a crystallographic twofold axis passing through the central benzene group. The benzene and triazole rings are almost coplanar with a dihedral angle of 5.5 (1)°. In the crystal, water mol-ecules are joined together by OW-H⋯OW hydrogen bonds to form a one-dimensional zigzag chain. These water chain...

An important aspect of evacuation planning is to save human population by sending the people in dangerous areas (sources) safe places (sinks). Optimization models for focus on regulating tra_c ow urban road networks so as maximize number evacuees reaching or minimize time evacuees. Recent studies show that reversing direction usual necessary segments increases and decreases signi_cantly. Howeve...

Betula platyphylla Suk (Asian white birch) is an economically important tree species in the paper-pulping and biofuel industries. To investigate mechanism of wood formation at metabolic level, we evaluated responses associated with tension-wood formation. Four-year-old trees were subjected to artificial bending treatment for 6 weeks. The xylem growth rate tension (TW) was significantly faster t...

In the title compound, C20H20Cl2N2O2·H2O, the piperidine ring adopts a chair conformation with the two substituent benzene rings inclined to one another [dihedral angle 84.63 (9)°]. In the crystal, the components are linked by Ow-H⋯O, N-H⋯Ow (w = water) and C-H⋯O hydrogen bonds, generating a sheet structure lying parallel to (101).

The asymmetric unit of the title compound, (C(12)H(12)N(2))(3)[V(10)O(28)]·2H(2)O, contains one half of a deca-vanadate anion, one and a half trans-1,2-bis-(4-pyridinio)ethene cations and one water mol-ecule. The V(10)O(28) groups are involved in a three-dimensional hydrogen-bonding network through Ow-H⋯O, N-H⋯O and C-H⋯O inter-actions.

by means of he's homotopy perturbation method (hpm) an approximate solution of velocity eld is derived for the ow in straight pipes of non-newtonian uid obeying the sisko model. the nonlinear equations governing the ow in pipe are for- mulated and analyzed, using homotopy perturbation method due to he. furthermore, the obtained solutions for velocity eld is graphically sketched and compared w...

Stems, skins, seeds, and pulp are grape pomace (GP) components formed as by-products during wine production. The GP share represents about 25% of the total amount processed grapes, which is a significant organic waste (OW) that can be treated in composting process. purpose paper to consider possibility their use by presenting basic characteristics potentials other available fractions OW agricul...
