Abstract This study aimed to evaluate the agronomic and structural characteristics of massai grass under grazing by sheep supplemented in the dry season. The treatments were supplements offered to sheep in massai grass pastures: multiple mixture, leucaena hay, gliricidia hay and soybean meal. The pastures were evaluated regarding: canopy height; forage accumulation and mass; accumulation, mass and percentage of morphological constituents; leaf:stem and green mass:dead material ratio; and pre‐ and ...

Abstract The reaction of tellurium(IV) tetrahalides with hydrochloric and hydrobromic acid leads to the formation of (H 3 O) 2 [TeX 6 ], which reacts subsequently with (2‐Br‐C 5 NH 5 ) + X ‐ to afford (2‐Br‐C 5 NH 5 ) 2 [TeCl 6 ] ( 1 ) and (2‐Br‐C 5 NH 5 ) 2 [TeBr 6 ] ( 2 ). The structure of the complex salts were analysed by X‐ray diffractometry affording the centrosymmetric space groups P2 1 /n (monoclinic, 1 ) and P1¯ (triclinic, 2 ). Interionic hydrogen bondings hold their lattices in bidimensional supramolecular arrays not yet described ...

The objective was to evaluate the productive and structural characteristics of tropical grasses and the performance of sheep supplemented during the dry season. The treatments consisted of Marandu, Piatã, Massai and Aruana cultivars managed under intermittent stocking with seven occupation days and 35 d of rest, with a variable stocking rate. The evaluated variables were the forage masses, the morphological components, the chemical composition of the pasture and sheep performance. The forage mass ...

The reaction of diphenylditelluride with 2-bromopyridine in hydrobromide or hydroiodide acid affords the tetrahalophenyltellurate(IV) [2-Br–C5NH5][PhTeX4] (X=Br and I). The structures of the two salts were characterised by single crystal X-ray diffractometry. The anionic units show a square pyramidal geometry about the tellurium atoms with the phenyl rings in the apical positions. Secondary, interanionic Te⋯X bonds as well as cation–anion H–X interactions hold the moieties in polymeric chains with ...

Cs[PhTeBr 4 ] was prepared by refluxing [2‐Br‐C 5 NH 5 ][PhTeBr 4 ] and CsCl in ethanol in the presence of an excess of HBr. In {Cs[PhTeCl 4 ]·CH 3 OH} the [PhTeCl 4 ] — units form dimers by secondary Te···Cl bonds with methanol molecules bridging adjacent Cs + cations. In both compounds, the alkali metal cation interacts secondarily with the chlorine and bromine Te‐ligands, achieving singular coordination polyhedrons ...

These parts are exposed, from the oil extraction to refining processes, to an environment that includes strong acids or bases, under high pressures, and high temperatures, up to 760 °C. Waspaloy (UNS N07001) is a material currently applied to manufacture components exposed to hot corrosion. This study evaluates the high temperature corrosion behavior of CrN, AlCrN, and TiAlN ...

Commercially pure titanium grades 1 (Ti), 2 (TiG2) and Ti–6Al–4V alloy grade 5 (TiG5) are used for many different types of biomaterials because of their excellent biocompatibility. Most of the biocompatibility of titanium is due to the formation of a passive thin oxide film (TiO2) in the presence of oxidant environments; it is basically found in two of its allotropic forms; rutile and anatase. The aim of this investigation was to evaluate the effect of thermal oxidation on effective thermal diffusivity ...

CpCr(NO)2Cl reacts in THF under reflux with the Na salt of 4,6-dimethyl-pyrimidin-2-thiol to give CpCr(NO)(DMPYS)·1/4 toluene (Cp=π-C5H5; DMPYS=4,6-dimethylpyrimidine-2-thiolato) and NaCl. The ligand substitution in CpCr(NO)2Cl probably occurs over displacement of NO followed by Cl− elimination. CpCr(NO)‘DMPYS’ crystallizes in the triclinic space group P1̄, formally with 25% of a toluene solvate molecule for each CpCr(NO)(DMPYS)-unity. In the new complex, the chromium atom shows a ‘tetrahedral’ coordination ...
