    A cliché that no one could deny today is one that sound as the following; “Knowledge is power”.We need to understand the fact that managing organizational knowledge recourses is as important as managing conventional organization resources.Knowledge management is a method, which aims to help organizations to effectively use knowledge.A knowledge audit is often the initial step of a knowledge management activity. Henczel (2000) highlighted that the low regard of knowledge audit has been a contributing factor to the top-heavy high knowledge management failures over the years. Though there are knowledge audit models proposed in the past by other researches, these models still have many drawbacks. This paper aims to address these drawbacks by proposing a 6-stage Knowledge Audit Model; derived from a comparative study on knowledge audit methodologies.These 6-stages are centered on core processes and integrates the development of appropriate knowledge management strategies.The practical implementation of this knowledge audit model for knowledge auditing allows for the investigation and analysis of the current knowledge environment, the measurement of the risk and opportunities faced by the organization with respect to its “knowledge health” and finally the recommendation of appropriate knowledge management strategies to be undertaken

    A binary hybrid replication strategy for improving availability and maintaining consistency of data in large scale mobile environments

    Data Management in mobile computing environments poses great challenges to the database researchers. One of the important challenges is to provide a data replication solution that maintains the consistency and improves the availability of replicated data. This paper addresses this problem for large scale distributed information systems that operate in mobile environments. Our solution represents a new binary hybrid replication strategy, in terms of its components and approach. The new strategy encompasses two components: replication architecture to provide a solid infrastructure for improving data availability and replication method to transfer data updates in a manner that achieves the consistency of data. The new strategy is a hybrid of both pessimistic and optimistic replication approaches, in order to exploit the features of each. The proposed strategy supports higher data availability and lower rate of inconsistencies as well as supports the mobility of users

    Chemical Characterisation of Bulk and Melt-spun Ribbons of NiMnIn alloy using Inductively Coupled Plasma Optical Emission Spectrometry

    Method development for the analysis of NiMnIn, a new magnetocaloric effect (MCE) material using inductively coupled plasma optical emission spectrometry (ICPOES) is discussed. Spectral interference of Ni and Mn on the analysis of In were studied. The process of method validation was carried out using various analytical techniques like conventional wet chemical techniques and instrumental techniques such as atomic absorption spectrometry. All the techniques show a close agreement in values, thus this method could be applied for regular analysis of NiMnIn alloys. A comparative chemical analysis of bulk and melt-spun ribbons of this alloy is also discussed.Defence Science Journal, 2011, 61(3), pp.270-274, DOI:http://dx.doi.org/10.14429/dsj.61.39

    Tetra­aqua­bis[3-(2-pyridylsulfan­yl)propionato N-oxide]nickel(II)

    In the centrosymmetric title compound, [Ni(C8H8NO3S)2(H2O)4], the NiII ion, which lies on an inversion centre, is six coordinated by four water mol­ecules and two propionate O atoms from two 2-pyridylsulfanylpropionate N-oxide ligands, forming a slightly distorted octa­hedral geometry. An intra­molecular O—H⋯O hydrogen bond stabilizes the mol­ecular conformation. The crystal packing is consolidated by inter­molecular O—H⋯O and C—H⋯O hydrogen bonding

    Effect of Ag+ ion Concentration on the Reaction Kinetics and Shape of Nanoparticles Synthesised by Green Chemical Approach

    The effect of varying Ag+ ion concentration on the green chemical reaction with a fixed tea aliquot concentration has been studied in detail with the help of UV-visible absorption spectra. With increase in the concentration of Ag+ solution the position of surface plasmon band systematically increased from 435 nm – 450 nm. The reaction followed first order kinetics and the rate of reaction increased in a linear fashion with k = 3.54 x 10-4 min-1 for 0.5 mL to k = 1.86 x 10-3 min-1 for 3.0 mL Ag+ solution. X-ray diffraction patterns showed an enhanced (200) reflection for 3.0 mL Ag sample. The shape of Ag nanoparticles could be effectively tuned from spherical to cuboid with increase in silver content as evidenced from scanning electron and transmission electron micrographs. The average particle size of Ag NPs increased from 25 nm to 55 nm with increase in the Ag+ content of the reaction

    In the crystal structure of the title compound, 4C21H22N2O2S2·0.5C3H6O·11.5H2O, there are four crystallographically independent mol­ecules (A, B, C, D) with similar geometries, 11 water mol­ecules and a solvent acetone mol­ecule which is disordered with a water mol­ecule with occupancy factors of 0.5:0.5. The dihedral angles formed by the mesitylene ring with the two pyridyl rings are 82.07 (3) and 78.39 (3)° in mol­ecule A, 86.20 (3) and 82.29 (3)° in mol­ecule B, 81.05 (3) and 76.0 (4)° in mol­ecule C, 86.0 (3) and 80.9 (3)° in moleule D. The two pyridyl rings form dihedral angles of 41.17 (4), 64.01 (3), 81.9 (3) and 82.25 (3)° in mol­ecules A, B, C and D, respectively. The crystal structure is stabilized by inter­molecular O—H⋯O hydrogen bonds and possible weak C—H⋯π inter­actions. Some short intra­molecular S⋯O contacts are apparent [2.684 (4)–2.702 (4) Å]
