For the comprehensive characteristics of hydro-turbine, it is generally grasped through full characteristic curve map hydro-turbine obtained from experiment. However, due to factors such as time cost, fund experimental difficulty and safety, results cannot hold onto each working condition hydro-turbine. And for specific conditions unknown conditions, linear interpolation needs be carried out ex...

Prasugrel {systematic name: 5-[(2-cyclo-propyl-carbon-yl)(2-fluoro-phen-yl)meth-yl]-4,5,6,7-tetra-hydro-thieno[3,2-c]pyridin-2-yl acetate}, C(20)H(20)FNO(3)S, is a new third-generation thienopyridine which was recently approved for clinical use as a more potent blocker of the platelet P2Y(12) receptor than clopidogrel, which was previously used for this purpose. The mol-ecule features a tetra-h...

A hydrogenerator’s cost price is considerably influenced by the used and computed design values. The most important parameters in the design of micro hydro power plants synchronous generators are the power blanket, the current density in the statoric winding and the air gap size. In this work we analyze the impact of these parameters on the cost price for a family of hydro power plant synchrono...

In the title complex, [PdBr(2)(C(13)H(18)N(2))(2)], the Pd(II) atom is situated on an inversion center. The tetra-hydro-pyrimidine group of the N-(2,4,6-trimethyl-phen-yl)-1,4,5,6-tetra-hydro-pyrimidine ligand is twisted from the square (PdN(2)Br(2)) coordination plane with a C-N-Pd-Br torsion angle of 81.8 (4)°; this is different from the angle of 43.47 (14)°, reported in a closely related str...

Iron-peroxide intermediates are central in the reaction cycle of many iron-containing biomolecules. We trapped iron(III)-(hydro)peroxo species in crystals of superoxide reductase (SOR), a nonheme mononuclear iron enzyme that scavenges superoxide radicals. X-ray diffraction data at 1.95 angstrom resolution and Raman spectra recorded in crystallo revealed iron-(hydro)peroxo intermediates with the...

The title compound, C28H34ClNO2 {systematic name: (E)-1-(4-chloro-phen-yl)ethanone O-[(1R,4aS,10aR)-7-isopropyl-1,4a-di-methyl-1,2,3,4,4a,9,10,10a-octa-hydro-phenanthrene-1-carbonyl]oxime}, was synthesized from de-hydro-abietic acid. In the de-hydro-abietyl moiety, the central and terminal cyclo-hexane rings display chair and half-chair conformations, respectively, and a trans-ring junction. Th...

In the title mol-ecule, C(25)H(19)N(3)O(3)S(3), the tetra-hydro-pyridine ring adopts a half-chair conformation. The dihedral angle between the least-squares plane through the tetra-hydro-pyridine ring and two thio-phene and two benzene rings are 6.25 (9), 89.49 (9), 76.43 (9) and 84.93 (8)°, respectively, while the dihedral angle between the 1,3,4-oxadiazole and tetra-hydro-pyridine rings is 81...

The hydro-chloride salt of isonicotinamide, C6H7N2O(+)·Cl(-), has been synthesized from a dilute solution of hydro-chloric acid in aceto-nitrile. The compound displays monoclinic symmetry (space group C2/c) at 150 K, similar to the related hydro-chloride salt of nicotinamide. The asymmetric unit contains one protonated isonicotinamide mol-ecule and a chloride anion. An array of hydrogen-bonding...
