Valuation effects of recent corporate dividend and income trust distribution tax changes
Authors: Amoako‐Adu Ben , Smith Brian F. 
Published: March 2008

AbstractWe analyze the valuation effects of the Canadian federal government's announcement on November 23, 2005 of a reduction in the taxation of corporate dividends and the announcement on October 31, 2006 of a plan to eliminate the tax‐deductibility of income trust distributions. Though high dividend stocks and income trusts reacted positively to the 2005 announcement, the abnormal returns were greater for income trusts. Conversely, both securities reacted negatively to the 2006 announcement with the decline bigger for income trusts. The larger price reactions of income trusts and the lack of statistical significance in the cross‐sectional tests of the abnormal returns suggest that the popularity of income trusts in Canada was mostly driven by their favourable income tax status. The implications of these findings for scholarship and for practice are discussed. Copyright © 2008 ASAC. Published by John Wiley & Sons, Ltd.
Precipitation Pattern Formation in the Presence of Imposed Concentration Gradients
Authors: ZHENG Ju‐Hua , WANG Qun , WANG Hai , GAO Qing‐Yu 
Published: March 2008

AbstractThis study explored precipitation pattern formation under conditions where the inner electrolyte was inhomogeneously distributed. Depending on the imposed concentration gradient, various new precipitation structures such as bifurcated segments, budding patterns, and Liesegang rings segregated with broken circles have been observed. The analysis illustrates that, despite the presence of an imposed concentration gradient, the location of Xn of the nth band and its time of formation tn still satisfy a simple law, but the spacing (Xn+1/Xn) of the precipitation bands departs from a linear relationship once broken rings are developed in the medium.
Amperometric Immunosensor for Prostate Specific Antigen Based on Co‐adsorption of Labeled Antibody and Mediator in Nano‐Au Modified Chitosan Membrane
Authors: LIN Jie‐Hua , ZHANG Li‐Juan , ZHANG Hui , ZHANG Shu‐Sheng 
Published: March 2008

AbstractA quasi‐reagentless amperometric immunosensor for prostate specific antigen (PSA) has been developed based on co‐adsorption of horseradish peroxidase (HRP) labeled PSA antibody (anti‐PSA) and tetramethyl benzidine (TMB) in nano‐Au modified chitosan membrane (Au‐chitosan). The immobilized TMB was used as an electron transfer mediator, which displayed a surface‐controlled process at scan rates less than 45 mV/s, and a diffusion‐controlled process at scan rates higher than 45 mV/s. The immunosensor with the co‐immobilized anti‐PSA and TMB was incubated with sample PSA antigen, and the formed immunoconjugate in the immunosensor was detected by a TMB‐H2O2‐HRP electrochemical system. Under the optimal experimental conditions, PSA could be determined in the linear range from 5.0 to 30 ng·mL−1 with a detection limit of 1.0 ng·mL−1. The prepared PSA immunosensor is not only economic due to the low‐cost ITO electrode obtained from industrial mass production, but also capable of batch fabrication with acceptable detection and storage stability.
Synthesis, Characterization and Antibacterial Activity of New 5‐(o‐Chlorophenyl)‐3‐(o,p‐dichlorophenyl)‐4,5‐dihydropyrazol‐1‐yl Oxime Ester Derivatives
Authors: LIU Xin‐Hua , SONG Bao‐An , ZHU Hai‐Liang , ZUO Ren‐Bing 
Published: March 2008

AbstractTen new 1‐(5‐(2‐chlorophenyl)‐3‐(2,4‐dichlorophenyl)‐4,5‐dihydropyrazol‐1‐yl) oxime ester derivatives were synthesized and characterized by elemental analysis, HRMS and 1H NMR data. All the compounds have been screened for their antibacterial potential in vitro against Bacillus subtilis, Staphylococcus aureus, Escherichia coli and Pseudomonas aeruginosa. The results show that 7c and 7f possess significant activity with the minimum inhibitory concentrations (MIC) value of 1.562 µg/mL against all the four bacteria. Compounds 7c, 7d and 7f show moderate inhibition against the DNA gyrase (IC50=1.6–2.5 µg/mL). On the basis of the biological result, the structure‐activity relationship was discussed.
Photobleaching of Hypocrellin B and 2‐Taurine Substituted Hypocrellin B in Plasma Solution
Authors: DING Hui‐Ying , ZHANG Yang , GU Ying , ZHAO Jing‐Quan 
Published: March 2008

AbstractPhotodynamic therapy (PDT) is a new methodology to utilize jointly a photosensitizer and light to destroy the target tissues of diseases via some photochemical reactions. On the other hand, the photosensitizer molecules may also be photo‐bleached during PDT, furthermore, their interaction with biomolecules and the photobleaching properties in blood vessels are critical to treatments of microvascular diseases. In consideration of these, the photobleaching processes of HB and its analogue THB in plasma solutions were investigated in the current work. It was observed that the photobleaching was predominately mediated by singlet oxygen reactions in well‐oxygenated aqueous solution in the presence of plasma substrate which not only greatly enhanced the photobleaching rate but also led to different photoproducts due to distinctly different reaction mechanisms. The relative photobleaching mechanisms were proposed based on the structural information and the redox potentials of the photosensitizers.

AbstractThree new prenylfuranoisoflavonoids, namely, 5‐hydroxy‐7‐(2‐hydroxyisopropyl)‐4′‐methoxy‐9‐prenylfurano [3,2‐g]isoflavone (1), 5‐hydroxy‐4′‐methoxy‐9‐prenylfurano[3,2‐g]isoflavone (2), 5‐hydroxy‐4′‐methoxy‐7‐prenyl‐furano[2,3‐h]isoflavone (3) were isolated from the roots of Hedysarum scopariu and structurally established by means of detailed spectroscopic analyses (IR, EI‐ or HR‐ESI‐MS as well as 1D‐ and 2D‐NMR), and by comparison of their spectroscopic data with those reported for structurally related compounds.
Mechanistic Investigations of Oxidation of Some Dipeptides by Sodium N‐chloro‐p‐toluenesulfonamide in Alkaline Medium:A Kinetic Study
Authors: PUTTASWAMY  , VAZ Nirmala , RAJENAHALLY VGOWDA Jagadeesh 
Published: March 2008

AbstractThe kinetics of oxidation of five dipeptides (DPP) viz., glycylglycine (Gly‐Gly), L‐alanyl‐L‐alanine (Ala‐Ala), L‐valyl‐L‐valine (Val‐Val), L‐leucyl‐L‐leucine (Leu‐Leu) and phenylglycyl‐phenylglycine (Phg‐Phg) by sodium N‐chloro‐p‐toluenesulfonamide or chloramine‐T (CAT) in NaOH medium was studied at 308 K. The reactions follow identical kinetics for all the dipeptides, being first‐order dependence each on [CAT]o, [DPP]o and fractional‐order on [OH−]. Addition of p‐toluenesulfonamide or halide ions (Cl− or Br−) has no significant effect on the rate of reaction. The reaction rate was found to increase with increase in ionic strength of the medium. The solvent isotope effect was studied using D2O. The activation parameters for the reaction were computed from Arrhenius plots. Equilibrium and decomposition constants were evaluated. The oxidation products of the dipeptides were identified as their corresponding aldehydes. An isokinetic relationship was observed with β=352 K, indicating that enthalpy factors control the reaction rate. CH3C6H4SO2NCl− of the oxidant has been postulated as the reactive oxidizing species. Under comparable experimental conditions, the rate of oxidation of the dipeptides increases in the order:Phg‐Phg>Ala‐Ala>Val‐Val>Leu‐Leu>Gly‐Gly. The kinetics of oxidation of the dipeptides have also been compared with those of their corresponding monomer amino acids. The observed results have been explained by a plausible mechanism and the related rate law has been deduced.

Authors: WU De‐Lin , JIA Zhao‐Li , SHI Jie‐Ping , SHI Zheng‐Wei , LU Guo‐Yuan 
Published: March 2008

AbstractThe new chromophore molecules with nonlinear optical (NLO) properties were prepared by Knoevenagel condensation from 4,5‐diformyl‐1,8‐dimethoxy‐9,10‐dihydroanthracene and thiobarbituric acid derivatives in the presence of piperidine and acetic acid. In these chromophores, the ring‐locked triene employed as a conjugation bridge and the thiobarbituric acid moiety was as an electron acceptor in a D‐π‐A units. The solvatochromism and UV spectra indicate that they have higher second‐order nonlinear polarizabilityμβvalues than the corresponding reference compound, without causing a large red shift of the charge transfer band.
A simplex model for layered niche networks
Authors: Fraundorf Philip 
Published: March 2008

AbstractThe standing crop of correlations in metazoan communities may be assessed by an inventory of niche structures focused inward and outward from the physical boundaries of skin (self), gene‐pool (family), and meme‐pool (culture). We consider tracking the progression from three and four correlation layers in many animal communities, to five of six layers for the shared adaptation of most humans, with an attention‐slice model that maps the niche‐layer focus of individuals onto the 6‐variable space of a 5‐simplex. The measure puts questions about the effect, on culture and species, of policy and natural events into a common context, and may help explore the impact of electronically mediated codes on community health. © 2008 Wiley Periodicals, Inc.

ASCOT Modelling of Ripple Effects on Toroidal Torque
Authors: Salmi A. , Johnson T. , Parail V. , Heikkinen J. , Hynönen V. , Kiviniemi T. P. , Kurki‐Suonio T. , JET EFDA Contributors  
Published: March 2008

AbstractToroidal field ripple, δ =(Bmax ‐Bmin )/(Bmax +Bmin ), in ITER will be relatively large, about 0.5% at the outer midplane. Due to the importance of toroidal rotation on plasma stability and confinement it is important to understand the consequences of a non‐negligible ripple field on rotation. Guiding centre following Monte Carlo code ASCOT is used to evaluate the torque on plasma from co‐current NBI in presence of toroidal magnetic field ripple. Simulations are made for a JET discharge from 2007 Ripple Campaign aimed to clarify the effect of ripple on fusion plasmas in preparation for ITER. ASCOT results show large reduction of torque from co‐NBI and negative torque from thermal ions, which together could create a counter rotating edge plasma. (© 2008 WILEY‐VCH Verlag GmbH & Co.

Ion Particle Transport in the Tokamak Edge Plasma
Authors: Stacey W. M. 
Published: March 2008

AbstractA generalized pinch‐diffusion transport relation previously derived from momentum conservation is combined with the continuity equation to derive a “generalized diffusion theory” for ion particle transport in the tokamak plasma edge inside the separatrix. The resulting generalized diffusion coefficients are evaluated for a representative experiment. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
3D Edge Transport Studies with EMC3‐EIRENE for the Dynamic Ergodic Divertor (DED) at TEXTOR
Authors: Harting D. , Reiter D. , Feng Y. , Schmitz O. , Reiser D. , Frerichs H. 
Published: March 2008

AbstractIn this paper we introduce some model extensions to the energy balances of the 3D fluid Monte‐Carlo code EMC3 and study their influence on the simulation results for TEXTOR‐DED. We implemented local kinetic corrections to the classical parallel heat conductivity of electrons (heat flux limit). Depending on the DED configuration, a cooling effect in the outermost SOL region, resulting from the heat flux limit, can be observed. In addition, also the adiabatic cooling term $1 \over 2$mnV2$\vec V$, which was neglected before, was implemented into the energy iterations. This term causes a localized cooling of the ions in front of the wall, where the plasma is accelerated towards the first wall. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Self‐Consistent Simulations of the Plasma‐Wall Transition Layer

Published: March 2008

AbstractIn the present work we develop a 1d3v (1D in space and 3D in velocity) kinetic Particle‐in‐cell model of the magnetised plasma‐wall transition layer, where the charged and neutral particle dynamics and interaction between them is included in a fully self‐consistent way. The plasma‐surface interactions are described via fixed emission coefficients for the secondary particles. We obtained different profiles of plasma and neutral particles and cross‐checked classical boundary conditions, which are usually formulated inside the PWT. (© 2008 WILEY‐VCH Verlag GmbH & Co.

Modeling of Hydrogen Lyman Line Profiles for Radiation Transport Studies in Edge Plasmas
Authors: Rosato J. , Capes H. , Godbert‐Mouret L. , Koubiti M. , Marandet Y. , Rosmej F. , Stamm R. 
Published: March 2008

AbstractAn analytical expression for the Lyman α line profile is proposed, for the purpose of radiation transport studies in divertor plasmas. It is shown that the coupling between Zeeman and Stark broadening has to be retained so as to describe accurately the line shape. This is confirmed by comparison to numerical simulations. The latter furthermore allow to quantify the accuracy of the Stark broadening model for the whole range of conditions encountered in divertors. Lyman α and Lyman β lines are investigated in details.

Integrated Modelling of Nitrogen Seeded JET Discharges
Authors: Zagórski R. , Telesca G. , Rapp J. , JET‐EFDA Contributors  
Published: March 2008

AbstractIn this paper we present results of numerical simulations of nitrogen seeded JET discharges. In particular, we have benchmarked the code against the type III ELMy JET pulses. In addition to recovering the main discharge parameters, the interplay between seeded nitrogen and intrinsic carbon is also reproduced. Predictions for the JET discharges with higher plasma current Ip = 3.5 MA and different input powers (14 < Paux < 23 MW) demonstrate that it is possible to achieve high radiation fractions (> 80%) and simultaneously reduce both the plasma collisionality and Zeff. Extrapolation to ITER shows compatibility of strongly radiative plasmas with the power amplification in excess of 10. (© 2008 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
