Various aspects of whistle-blowing in engineering are discussed. Firstly, information is given on the terms related to the subject, and necessary conditions for whistle-blowing are considered. Then, the problems usually encountered by whistle-blowers and precautionary measures to be taken by them are presented. Finally, the approaches that can be followed by the organizations to remedy the difficulties caused by whistle-blowing are mentioned.
Let F be a free group of rank d ? 2. Consider the quotient F/[?4 (F'), F]F?. A peculiar feature of this group is the occurence of torsion in its centre. In this article, we describe an elementary abelian 2-group of rank in F /[?4(F'), F]F? in terms of generators of F. We solve this purely group theoretic problem using homological methods namely computing certain connecting homomorphisms.
The investigation of pressureless sintering of Si3N4 ceramics with oxide additives in different packing powder was presented. Si 3N4-5% MgO mixtures were densified in different packing powders in the carbon furnace for 30 min under a nitrogen atmosphere, to determine an optimum packing powder and to show the effect of packing powder. The weight losses inevitably occur due to the volatility of MgO, when MgO-containing silicon nitride mixes are pressureless sintered. The maximum density was obtained at sintering temperatures of 1650°C, from the samples that were pressureless sintered with additional silica.
The chemical analysis of coniferous wood species occuring in Turkey was presented. Three trees were chosen from each species of coniferous woods and three discs were taken from each tree, the first from the bottom of the stem, the second from the middle, and the third from the upper part. The samples taken from each disc were divided into sapwoods and heartwoods and chipped into matchstick size splinters. The chemical analysis of Turkish coniferous wood species were found useful to present comparative results with regards to both technical utilization and scientific purposes.
The title compound, [NiCl2(C11H14N2O)(2)], was synthesized from 1-(2-ethoxyethyl)benzimidazole and nickel dichloride in ethanol and is isostructural with its cobalt analogue. It shows a distorted tetrahedral geometry about Ni-II, involving two Cl atoms and two benzimidazole N atoms. The crystal structure is stabilized by C-H...Cl and C-H...O interactions.
