The issue network: reshaping the stakeholder model
Authors: Frooman Jeff 
Published: July 2010

AbstractWho is a stakeholder? In this paper, stakeholders are defined in terms of who has a stake in an issue instead of who has a stake in a firm, and in so doing introduces the idea of an “issue network.” Drawing on concepts familiar to the social movements (sociology) and interest groups (political science) literatures, I argue that members of an issue network can be identified as those with grievances, resources, or opportunities. To illustrate this argument, I consider the issue of land use in the western United States, showing how various environmental organizations might fit into such a land use network. I conclude with the INSPIRE model, which locates my argument in this larger model of stakeholder management currently being constructed in the stakeholder literature. Copyright © 2010 ASAC.

Authors: Ghosh Prabir , Samanta A. N. , Ray Subhabrata 
Published: July 2010

AbstractReduction of chemical oxygen demand (COD) value of petrochemical industry wastewater (COD ∼11 500 mg/L) by Fenton's oxidation has been investigated. Batch tests were conducted on the effluent samples to determine the optimum process conditions. Fenton's oxidation process was found to effectively reduce the COD by 97.5% in 100 min. Effects of different process parameters: pH, H2O2 dosage, Fe2+ dosage, H2O2/Fe2+ ratio, temperature were investigated. The optimum conditions were at pH 3, H2O2 concentration 3 M, Fe2+ concentration 0.06 M and temperature 30°C. Optimum molar ratio [H2O2/Fe2+] was 50:1. At optimum conditions, 97.5% COD reduction was achieved for the typical effluent sample from nearby industry manufacturing mainly PET resins.On a analysé la réduction de la valeur demande chimique en oxygène (DCO) des eaux usées de l'industrie pétrochimique (DCO ∼11 500 mg/L) par oxydation de Fenton. Des essais par lots ont été réalisés sur les échantillons d'effluent dans le but de déterminer les conditions de processus optimales. On a découvert que le processus d'oxydation de Fenton a réduit efficacement la DCO de 97,5% en 100 min. Les effets de différents paramètres de processus, soit pH, dose de H2O2, dose de Fe2+, rapport H2O2/Fe2+ et température ont été analysés. Les conditions optimales étaient pH 3, concentration de H2O2 3 M, concentration de Fe2+ 0,06 M et température 30°C. Le rapport molaire optimal [H2O2/Fe2+] était de 50:1. À des conditions optimales, on est parvenu à une réduction de DCO de 97,5% pour l'échantillon d'effluent typique de l'industrie à proximité qui fabrique principalement des résines de PET. Can. J.

High Sensibility of Quantum Dots to Metal Ions Inspired by Hydroxyapatite Microbeads
Authors: Wang Xiang , Fang Zheng , Liu Jinku , Zhong Xinhua , Ye Bangce 
Published: July 2010

AbstractAn approach for the sensitive and selective determination of Ag+, Cu2+ and Hg2+ ions was developed based on the fluorescence quenching of mercaptopropionic acid (MPA) capped CdTe quantum dots in the existence of hydroxyapatite (HAP) nanoribbon spherulites. Among various metal ions investigated, it was found that the fluorescence of CdTe QDs was only sensitive to Ag+, Cu2+ and Hg2+ ions. The addition of HAP into the CdTe system could bring forward a sensitivity improvement of about 1 to 2 orders of magnitude in the detection of Ag+ and Cu2+ compared with the plain CdTe system without the existence of HAP; while there was no sensitization effect for Hg2+. Under optimal conditions, the detection limits for Ag+, Cu2+ and Hg2+ were 20, 56 and 3.0 nmol·L−1, respectively, and the linear ranges were 0.02–50, 0.056–54 and 0.003–2.4 µmol·L−1, respectively. Mechanisms of both QDs fluorescence quenching by metal ions and the sensitization effect by HAP were also discussed.

Published: July 2010

AbstractThe synthesis and characterization of dimeric lanthanide amides stabilized by a dianionic N‐aryloxo functionalized β‐ketoiminate ligand are described in this paper. Reactions of 4‐(2‐hydroxy‐5‐tert‐butyl‐phenyl)imino‐2‐pentanone (LH2) with Ln[N(SiMe3)2]3(µ‐Cl)Li(THF)3 in a 1:1 molar ratio in THF gave the dimeric lanthanide amido complexes [LLn{N(SiMe3)2}(THF)]2 [Ln=Nd (1), Sm (2), Yb (3), Y (4)] in good isolated yields. These complexes were characterized by IR spectroscopy, elemental analysis, and 1H NMR spectroscopy in the case of complex 4. The definitive molecular structures of complexes 1, 3, and 4 were determined. It was found that complexes 1 to 4 can initiate the ring‐opening polymerization of L‐lactide.

Published: July 2010

AbstractThe binding distances of fluorescein to bovine serum albumin (BSA) in formamide‐water andN,N‐dimethyl‐ formamide‐water mixtures were determined by fluorescence quenching method and compared with the values in urea‐water mixtures in our previous work. The results, together with the analysis of fluorescence spectra, were utilized to probe the conformational stability of protein in aqueous amides, providing a further insight into the mechanism of urea acting on protein. The spectral properties of BSA showed significant difference in the aqueous solutions of the three kinds of amide and indicated that both NH2group and C=O group could form hydrogen bond with the protein, serving as donor and acceptor, respectively. However, the results revealed that the multiple hydrogen bonds of NH2group with back bond and hydrophilic side chains of the protein played a key role in the nonspecific urea‐mediated network of intramolecular interaction due to its higher hydrogen bonding capability compared to C=O group.
Spectrophotometric Study on Kinetics of Solvatochromism of Methyl Violet in Aqueous Methanol
Authors: Saeed Rehana , Ashfaq Maria , Fahimuddin  
Published: July 2010

AbstractThe kinetics of the reaction of methyl violet with iodide in aqueous methanol system was studied by spectrophotometric method. The rate of reaction of methyl violet in different alcoholic composition in presence of potassium iodide was observed at pH 4 and 6 at various temperatures (298–318 K). Solvatochromic effect was studied in different percentages of methanol (0–50%). Bathochromic shift was observed with the decrease in polarity of solvent. The color change was attributed to molecule's structure, the delocalization of unit electrical charge causes deepening of color and decrease of delocalization causes fading of color due to reduction of dye. Increase in the rate of reaction was observed with increase in alcoholic content and also affected by potassium iodide salt and increased with increase in concentration of potassium iodide. Energy of activation (Ea) and transition energy (ET) were calculated with the help of kinetic data. Thermodynamic parameters such as enthalpy change of activation (ΔH*), Gibbs free energy change of activation (ΔG*) and entropy change of activation (ΔS*) were evaluated as a function of concentration of solvent and salt.
Photoinduced Excited State Intramolecular Proton Transfer of New Schiff Base Derivatives with Extended Conjugated Chromophores: A Comprehensive Theoretical Survey
Authors: Wang Qi , Gao Fang , Li Hongru , Zhang Shengtao 
Published: July 2010

AbstractThis paper presented comprehensive theoretical investigation of excited state intramolecular proton transfer (ESIPT) of four new large Schiff base derivatives with extended conjugated chromophores. The properties of the ground state and the excited state of phototautomers of C1 to C4 [C1: 2‐(4′‐nitro‐stilbene‐4‐ylimino)methylphenol; C2: 2‐(4′‐cyano‐stilbene‐4‐ylimino)methylphenol; C3: 2‐(4′‐methoxyl‐stilbene‐4‐ylimino)methylphenol; C4: 2‐(4′‐N,N‐diethylamino‐stilbene‐4‐ylimino)methylphenol], which included geometrical parameter, energy, rate constant, frontier orbit, Mulliken charge, dipole moment change, were studied by DFT (density functional theory), CIS (configuration interaction singles‐excitation), TDDFT (time‐dependent DFT) methods to analyze the effects of chromophore part on the occurrence of ESIPT and the role of substituent groups. The structural parameter calculation showed that the shorter RHN and larger ROH from enol to enol* form, and less twisted configuration in the excited state implied that these molecules could undergo ESIPT as excitation. Stable transition states and a low energy barrier were observed for C1 to C4. This suggested that chromophore part increased some difficulty to undergo ESIPT for these molecules, while the possibility of occurrence of ESIPT was quite high. The negative ΔE* (−9.808 and −9.163 kJ/mol) of C1 and C2 and positive ΔE* (0.599 and 1.029 kJ/mol) of C3 and C4 indicated that withdrawing substituent groups were favorable for the occurrence of ESIPT. The reaction rate constants of proton transfer of these compounds were calculated in the S0 and S1 states respectively, and the high rate constants of these compounds were observed at S1 state. C1 even reached at 1.45×1015 s−1 in the excited state, which is much closed to 2.05×1015 s−1 of the parent moiety (salicylidene methylamine). Electron‐donating and electron‐withdrawing substituent groups had different effects on the electron density distribution of frontier orbits and Mulliken charges of the atoms, resulting in different dipole moment changes in enol*→keto* process. These differences in turn suggested that C1 and C2 had more ability to undergo ESIPT than C3 and C4. The ultraviolet/visible absorption spectra, normal fluorescence emission spectra and ESIPT fluorescence emission spectra of these compounds were predicted in theory.
Highly Efficient Syntheses of β‐Cyanoketones via Conjugate Addition of Me3SiCN to Aromatic Enones
Authors: Yang Jingya , Chen Fuxue 
Published: July 2010

AbstractAn efficient 1,4‐addition of Me3SiCN to aromatic enones has been achieved with excellent yields (91% –99%) using CsF (1 mol%) as the catalyst and H2O (4 equiv.) as the additive in refluxing dioxane within 7 h. The perfect regioselectivity is proposed accounting from H2O‐facilitated reversion of the 1,2‐adduct in the presence of CsF and subsequent irreversible 1,4‐addition reaction.

Published: July 2010

AbstractThe COOH in fluorescein isothiocyanate (FITC) reacted with NH in piperidine (P) to form FITC‐P on the center of indentation of polyamide membrane (PAM) when drying for 2 min at (92±1)°C. Then, the FITC‐P diffused outward from the indentation center and formed the round SOR‐P‐FITC (containing the FITC‐P self‐ordered rings). Thus, multi‐FITC accumulated on SOR‐P‐FITC, leading to the enhancement of RTP signal on bio‐target, whose Ip increased 2.0 times compared with non‐generated SOR. When bovine serum albumin (BSA) was added to the center of SOR‐P‐FITC, NCS of FITC in SOR‐P‐FITC reacted with NH2 of BSA to form SOR‐P‐FITC‐BSA, which caused the RTP signal of FITC to enhance sharply. The ΔIp of the system was 3.4 times higher than that without β‐CD and 4.0 times higher than that without SOR‐P‐FITC formed. Its ΔIp was linear to the content of BSA. Therefore, a new solid substrate‐room temperature phosphorimetry (SS‐RTP) for the determination of trace protein was established using SOR‐P‐FITC as a phosphorescent probe. Under the optimum condition, the linear range of this method was 0.040–16.0 ag·spot−1 with a detection limit (LD) of 8.5 zg·spot−1 (0.40 µL sample solution per spot, the corresponding concentration was 2.1×10−17 g·mL−1), and the regression equation of working curve was ΔIp=3.848+4.240mBSA (ag·spot‐1), n=6, correlation coefficient (r) was 0.9993. This method with high sensitivity had been applied to determining the content of trace protein in the water samples, and the results coincided well with those obtained with pyrocatechol violet‐Mo(VI) method (P.V.M.M.). At the same time, the mechanism of SS‐RTP using SOR‐P‐FITC as a phosphorescent probe (SOR‐P‐FITC‐SS‐RTP) was discussed.
Determination of Cymoxanil Fungicide in Commercial Formulation and Natural Water by Square‐wave Stripping Voltammetry
Authors: Mercan Hülya , İnam Recai 
Published: July 2010

AbstractVoltammetric behavior of cymoxanil fungicide dissolved in water–acetonitrile (1:1) solution was investigated by square‐wave stripping voltammetry (SWSV) and cyclic voltammetry (CV). The cymoxanil was accumulated at −400 mV on a hanging mercury drop electrode (HMDE) and a well‐defined cathodic peak obtained at −680 mV (pH 7.0). The optimal experimental parameters for the cymoxanil assay were an accumulation potential of −400 mV (vs. Ag/AgCl/KCl), accumulation time 10 s, frequency 350 Hz, and pulse amplitude 75 mV. The cyclic voltammetric measurements showed an irreversible nature of the reduction wave at HMDE in the range of scan rates comprised between 5 and 4000 mV/s. The calibration curve obtained from SWSV was linear in the range 23.6–1950 µg/L with a detection limit of 7.1 µg/L. The method was applied to the direct determination of fungicide in water samples. Recoveries calculated for river and tap water samples spiked with 40 µg/L level were 40.2 ± 0.8 and 39.8 ± 0.9 µg/L at 95% confidence level, respectively. The method was extended to determination of cymoxanil in agrochemical formulation Tri‐Miltox Max® with recovery of 102.5%. The sufficiently good recoveries and low relative standard deviations reflect the high accuracy and precision of the proposed square‐wave voltammetric method. Influences of some interfering species were also investigated.
Optimizing Gaussian filtering of volumetric data using SSE
Authors: Vaško A. , Šrámek M. 
Published: July 2010

AbstractGaussian filtering is a basic operation commonly used in numerous image and volume processing algorithms. It is, therefore, desirable to perform it as efficiently as possible. Over the last decade CPUs have been successfully extended with several SIMD (Single Instruction Multiple Data) extensions, such as MMX, 3DNow!, and SSE series. In this paper we introduce a new technique for Gaussian filtering of volume data sets—the extended volume—together with its SIMD implementation using the SSE technology. We further introduce a SIMD optimized recursive IIR implementation of the Gaussian filter, and finally, we parallelize the SSE versions with the help of OpenMP (Open Multi‐Processing). Experimental evaluation indicates that the SIMD implementation can significantly speed up both versions of the Gaussian filtering and that the non‐recursive extended volume version is faster than the recursive IIR one for small widths of the Gaussian filter.
