Disclosing elements of disclosure: a test of legitimacy theory and company ethics
Authors: Lightstone Karen , Driscoll Cathy 
Published: March 2008

AbstractThis paper focuses on some of the ethical issues related to voluntary disclosure of qualitative information by Canadian public companies. Drawing on various organizational theories, we examine some of the ways that companies can symbolically manage legitimacy through disclosure. Press releases of a sample of companies that received cease‐trading orders were analysed for their use of language. We found that high‐risk companies attempted to manage legitimacy by selectively releasing information and by using ambiguous language. Moreover, some companies behaved unethically by using language that suggested a positive future despite the imminent release of a cease‐trading order. These findings have implications for organizational and accounting theorists and stakeholders in the corporate, fiduciary, and investment communities. Copyright © 2008 ASAC.

Copper(II) and Cobalt(II) Dinuclear Complexes with Oxime‐based Ligand as Catalysts for the Hydrolysis of Phosphate Diester
Authors: DU Juan , MENG Xiang‐Guang , ZENG Xian‐Cheng 
Published: March 2008

AbstractDinuclear copper(II) and cobalt(II) complexes were prepared and investigated with respect to their effects on hydrolysis of bis(4‐nitrophenyl) phosphate (BNPP). The kinetic data indicated that the mono‐deprotonated oxime group could act as an effective intramolecular nucleophile in the reaction. The higher reactivity of dinuclear copper(II) complex than that of its mononuclear analogues illustrated the probability of double Lewis acid activation by two metal centers in the former complex.

Published: March 2008

AbstractA novel energetic salt 1,5‐diamino‐4‐hydro‐1,2,3,4‐tetrazolium 3,5‐dihydroxy‐2,4,6‐trinitrophenolate was synthesized by the reaction of 1,5‐diamino‐1,2,3,4‐tetrazole (DAT) with 2,4,6‐trinitro‐1,3,5‐trihydroxybenzene (trinitrophloroglucinol, TNPG). It was characterized by X‐ray single crystal diffraction, elemental analysis, FT‐IR spectroscopy and 1H NMR. The title compound crystallizes in monoclinic system, P2(1)/c space group with crystal parameters of a=1.3399(3) nm, b=0.47088(9) nm, c=2.0127(4) nm, β=92.83(3)°, V=1.2684(4) nm3, Z=4. Hydrogen bonds, electrostatic interactions, and weak van der Waals′ forces make the molecules form a stable three‐ dimensional net structure. Mulliken charge distribution and overlap population of DAT and DATH+TNPG− in bulk state have been obtained from the density functional theory (DFT) with the B3LYP method employing the 6‐31G∗︁ ∗︁ basis sets to interpret the reason why the protonation site of DAT is N(4) atom of the tetrazole ring. Thermal decomposition of the title compound was studied by using differential scanning calorimetry (DSC) and thermogravimetric analysis (TG) techniques. The high enthalpy change and leaving no solid residue after thermal decomposition indicate that the title compound can be used as a promising energetic material or gas‐generating composition. The kinetic parameters of the exothermic process of DATH+TNPG− were studied by using Kissinger′s and Ozawa‐Doyle′s methods and the Arrhenius equation of this process was obtained.

Authors: UMMATHUR Muhammed Basheer , KRISHNANKUTTY Krishnannair 
Published: March 2008

AbstractA new series of β‐ketoanilides, in which the keto group attached to an olefinic linkage, have been synthesized by the reaction of acetoacetanilide with p‐substituted benzaldehydes (4‐methoxybenzaldehyde, 4‐ethoxybenzaldehyde, 4‐dimethylaminobenzaldehyde and 4‐nitrobenzaldehyde) under specified conditions. The existence of these β‐ketoanilides predominantly in the intramolecularly hydrogen bonded enol forms has been well demonstrated from their IR, 1H NMR and mass spectral data. Details on the formation of [ML2] complexes of these compounds with Ni(II), Cu(II) and Zn(II) and their nature of bonding were discussed on the basis of analytical, IR, 1H NMR and mass spectral data.
Morphology‐controlled Synthesis of SiO2 Hierarchical Structures Using Pollen Grains as Templates
Authors: GUAN Zi‐Sheng , ZHANG Yu , LU Chun‐Hua , XU Zhong‐Zi 
Published: March 2008

AbstractRape‐, sweet potato‐ and camellia‐pollen‐templated SiO2 hierarchical structures with species‐specific surface morphologies were prepared through a facile surface sol‐gel and succedent calcination process. Various‐morphology SiO2 replicas with complex structures, such as about 50‐µm‐length and 20‐µm‐width high‐fidelity ellipsoidal replicas with about 5‐µm uniform meshes, about 40‐µm spheres with 2‐µm taper‐like protuberances and 15‐µm spheres with troughs, were obtained from using rape‐, sweet potato‐ and camellia pollen grains as templates, respectively. The results of N2 adsorption‐desorption isotherms indicate that both rape‐ and camellia‐pollen‐ templated SiO2 replicas show type IV‐like isotherm with the characteristics of mesoporosity and corresponding Brunauer‐Emmett‐Teller (BET) surface areas are 10.5 and 5.2 m2·g−1, respectively. The Barrett‐Joyner‐Halenda (BJH) pore size distribution of the rape‐pollen‐templated SiO2 replicas presents smaller pores centered at 3.6 nm and bigger pores centered at 8.6 nm with a broad distribution whereas the camelliapollen‐templated SiO2 replicas display narrow BJH pore size distribution centered at 20 nm. The biofabrication procedure using ubiquitous, inexpensive and environment‐friendly pollen grains as a biotemplate holds a promise as a simple route to construct controlled complex porous oxides via simple chemical methods.

AbstractA copper coordination compound ZZF51(A) named bis(5‐butyl‐2‐pyridinecarboxylato‐N1,O2)‐copper, the first time found in the nature, was isolated from a marine endophytic fungus Fusarium sp. ZZF51 from the South China Sea coast. Its structure was elucidated using spectroscopic methods and single crystal X‐ray diffraction analysis. The antimicrobial cytotoxicity experiments exhibited that ZZF51(A) had mutagenicity activities against four aerobic reference strains Staphylococcus aureus, Bacillus subtilis, Escherichia coli, and Salmonella enteritidis with respective MIC values of 12.5, 25, 12.5, and 50 µg/mL. The anti‐cancer tests showed that the compound had strong inhibitory activities against three human cancer lines KB, KBv200, and HepG2 with IC50 values of 3.54, 3.68 and 25.12 µg/mL respectively. In the course of investigating the source of ZZF51(A) in biomass, it was found that the output of ZZF51(A) was largely influenced by the amount of CuCl2 in the liquid medium, and the fungus (No. ZZF51) had two notable characteristics:endurance of high concentration Cu(II) ions and biosorption of Cu(II) ions.

The Role of Zinc(II) in the Absorption–Desorption of CO2 by Aqueous NH3, a Potentially Cost‐Effective Method for CO2 Capture and Recycling
Authors: Mani Fabrizio , Peruzzini Maurizio , Barzagli Francesco 
Published: March 2008

AbstractThe absorption of CO2 by aqueous NH3 solutions has been investigated at atmospheric pressure and 0 °C. The CO2 absorption is fast and occurs with high efficiency (88–99 %). The maximum CO2‐removal efficiency increases slightly with the NH3 concentration. Addition of zinc(II) salts (as chloride, nitrate or sulfate) to the NH3 absorbent solution increases the overall CO2‐absorption capacity without appreciably affecting the removal efficiency. Stripping of pure CO2 from HCO3− solutions is achieved by adding the calculated amount of ZnII salts, which under ambient conditions lead to rapid release of about 30–35 % of the initially captured CO2. At the same time, about 65–70 % of the captured CO2 is transformed into solid basic zinc carbonates. The recovery of these valuable solid products and the release of only 1/3 of free CO2 at room temperature and pressure reduces the cost of the overall process of CO2 capture, making it a potentially attractive method for CO2 capture on a larger scale.
Disparate Scale Nonlinear Interactions in Edge Turbulence

Published: March 2008

AbstractIn this topical review, we explain the recent achievement in the study of nonlinear interactions, putting an emphasis on the relevance to edge turbulence. First, we start from the survey of the essence in the nonlinear theory of drift wave ‐zonal flows systems, and visit the experimental observations of the nonlinear interactions of tokamak edge turbulence. Secondly, the universality of intermittent convective transport in the SOL of different magnetic devices are shown. Then, we discuss evolution of collisional drift wave instability in the linear plasma configuration, which is bounded by end plates having analogy to SOL plasmas. By introducing the Numerical Linear Device, the intermittent evolution of large‐amplitude instabilities, generation mechanism of the poloidal flow and other nonlinear process are examined.

Suite of Verification Test Problems for Edge Turbulence Simulations
Authors: Umansky M. V. , Cohen R. H. , LoDestro L. L. , Xu X. Q. 
Published: March 2008

AbstractWe present a suite of test problems that are used for verification of the edge turbulence code BOUT. BOUT is an electromagnetic fluid turbulence code for tokamak edge plasma that performs time integration of reduced Braginskii plasma fluid equations, using spatial discretization in realistic geometry and employing a standard ODE integration package PVODE. Recently the code underwent a substantial redesign and extensive verification testing. In the verification process, a series of linear and nonlinear test problems was applied to BOUT targeting different subgroups of physical terms. The tests include reproducing basic electrostatic and electromagnetic plasma modes in simplified geometry, axisymmetric benchmarks against the 2D edge code UEDGE in the actual DIII‐D tokamak divertor geometry. Successful passing of these tests by BOUT gives strong evidence that equations in the code are solved correctly. Although the tests were developed specifically for the BOUT code they can well be applied for verification of other codes used for simulations of edge turbulence. (© 2008 WILEY‐VCH Verlag GmbH & Co.

Published: March 2008

AbstractDrift‐wave turbulence in the linear VINETA [1] device was studied using the adapted version [2] of the threedimensional gyrofluid code GEM3 [3]. The density and parallel velocity gyrofluid equations of electrons and ions for the cylindrical annulus are solved. It is shown that the code is able to reproduce the main experimental signatures of intermittency. The influence of the interaction of the plasma with neutrals – the so‐called ‘neutral wind’ – on the intermittent turbulence in VINETA is discussed. (© 2008 WILEY‐VCH Verlag GmbH & Co.

Published: March 2008

AbstractMeso‐scale structures, driven by curvature and gradB effects, like blobs and ELMs play a very important role in edge and SOL plasma transport in tokamaks. Here we discuss rather simple model describing the formation of blobs. The model is based on coupled drift‐wave and ballooning effects. Both analytic and preliminary numerical results are reported.

Published: March 2008

AbstractThe radial eigenmode of the geodesic acoustic mode (GAM) is investigated, taking into account the finite ion Larmor radius effect. The radial eigenfunction and the eigenfrequency (real frequency and damping rate) are obtained numerically. The eigenfrequency is found to be not continuous, but discrete. In addition, we obtain an analytic expression for the real eigenfrequency, which shows good agreement with numerical results. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Modelling of the Radial Electric Field in the ASDEX Upgrade Ohmic Shots
Authors: Rozhansky V. , Kaveeva E. , Voskoboynikov S. , Coster D. P. , ASDEX Upgrade Team  
Published: March 2008

AbstractSeveral ASDEX‐Upgrade Ohmic shots with different densities and temperatures corresponding to different collisionality regimes at the separatrix were simulated with transport code B2SOLPS5.0. The expression for the parallel viscosity was extended to be consistent with the neoclassical electric field in all collisionality regimes including plateau and banana regimes. It is demonstrated that for all shots in the core region deeper than the viscous layer (of the order of 1cm inside the separatrix) the relation between the radial electric field, parallel velocity, density and temperature gradients is close to the neoclassical one. This is consistent with the results of many simulations performed earlier for the collisional regimes. The contribution from the toroidal velocity, which is generated in the SOL and transported further to the core, to the radial electric field profile is found to be modest and comparable with density and temperature gradient contribution. The simulation results do not reproduce the dependence of the poloidal velocity of the turbulence on the collisionality measured in [1] deep inside the core. On the other hand, the shape of the radial electric field in the separatrix vicinity both inside and outside the separatrix is consistent with the measured poloidal rotation velocity of the turbulence.

Published: March 2008

AbstractNeutral particle behavior in the linear divertor simulator material and plasma(MAP)‐II is studied with Monte Carlo simulation code DEGAS. Various model cases are simulated to compare the results with the attached and detached plasma condition. Neutral particle distribution depends upon the location of particle sources/sinks. H alpha spectra shape depends also upon plasma temperature and density and there exist a few dominant pathways to produce excited H atoms. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Benchmarking Kinetic and Fluid Neutral Models with Drift Effects
Authors: Hoshino K. , Toma M. , Hatayama A. , Coster D. P. , Bonnin X. , Schneider R. , Kawashima H. , Asakura N. , Suzuki Y. 
Published: March 2008

AbstractA kinetic neutral model and a fluid neutral model have been benchmarked under the detachment condition. The upstream radial profiles of basic plasma and neutral parameters with the fluid neutral model are carefully fitted to that with the kinetic model, while no such an attempt has been made in the divertor region as a first step of the benchmark study with the effects of drifts. At the mid‐plane, no significant effects of the drifts on the radial profile of the basic plasma parameters are seen. However, in the divertor region, large differences of the benchmark result are seen even without the effects of drift. Effects of drift tend to enlarge the difference. Therefore, improvement of the fluid neutral model or optimizations of the free parameters are needed to analyze the effects of drifts in the divertor region, especially for the detached state. Otherwise, the kinetic model should be used to analyze the divertor characteristics even without the effects of drifts. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)

AbstractThe coupled dynamics and kinetics between gas and plasma in the sheath region in the divertor is studied by means of a one‐dimensional Particle in Cell‐Direct Simulation Monte Carlo (PIC‐DSMC) model. In particular, the electron‐induced vibrational excitation/relaxation of H2 molecules and particle‐surface interaction (vibrational relaxation, atom recombination, ion neutralization, direct negative ion production) have been considered in detail in view to estimate the importance of plasma volumetric recombination by molecular assisted reactions (MAR) and the possible electron heating near the wall.

Simulation Study of Radiative Cooling in the Divertor on JT‐60 Super Advanced (JT‐60SA)
Authors: Suzuki Y. , Kawashima H. , Coster D. P. , Sakurai S. , Shimizu K. , Takizuka T. 
Published: March 2008

AbstractA simulation study of the divertor for JT‐60SA is discussed in both double‐null (DN) and single‐null (SN) configurations. In the DN case, the transition of peak heat load on the targets and divertor plasma states from CDN (connected double‐null) to DDN (disconnected double‐null) are shown in the simulation. The radiative cooling power in the divertor plasma is discussed in this study. The carbon impurity generated by the sputtering on the divertor target is included in the simulation. In the gas puffing cases of fueling gas (D2) and impurity gas (Ne), the reduction of heat load is confirmed consistently with increasing the radiative cooling loss power in the diverter plasma. The loss power and the distribution of radiative cooling in the divertor plasma are studied in this paper. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
