Villes en transition : imaginer des relocalisations en urgence
Authors: Semal Luc , Szuba Mathilde 
Published: September 2010

Résumé Changer le système ou changer les pratiques ? Selon Luc Semal et Mathilde Szuba, les promoteurs des Villes en transition renouvellent les réponses apportées à cette question en mêlant systématiquement à leur approche de la justice climatique l’échéance du pic pétrolier, peut-être déjà là. Ainsi, il ne suffirait pas de « revendiquer » mais il faudrait « s’y préparer » matériellement et psychologiquement. Mobilisant les concepts de résilience et de relocalisation, les « transitionneurs », souvent proches du mouvement altermondialiste, seraient porteurs d’un nouveau projet « d’émancipation sous contrainte ».

Jardinières du commun
Authors: Petrescu Doina 
Published: September 2010

Résumé L’article aborde la question de la réinvention du commun comme un travail relationnel et différencié dans lequel la subjectivité féminine a un rôle actif à jouer. Elle montre que ce travail de reconquête, de réappropriation et de reconstruction a besoin de situations spécifiques où il puisse s’agencer, d’espaces actifs, mais aussi de personnes actives, d’agents, de sujets porteurs de cette réinvention. Fondé sur des observations puisées de l’expérience de l’auteur comme membre de l’atelier d’architecture autogérée, l’article parle de ce processus de réinvention du commun qui est aussi un processus de résubjectivation collective dont les agents sont pour la plupart des femmes.

Effects of dispersion and arrangement of clay on thermal diffusivity of polyimide‐clay nanocomposite film
Authors: Kakiage Masaki , Ando Shinji 
Published: September 2010

AbstractPolymer‐clay nanocomposites are well‐known high‐performance materials with a superior tensile modulus. However, in the case of composites with polyimide (PI), additional functions require study because PI is a high‐performance material in itself. Significant enhancement of thermal conductivity, which is closely related to the state of clay dispersion, is expected for a polymer‐clay nanocomposite. In this study, variations in the thermal diffusivity of PI‐clay nanocomposite films prepared by different methods were investigated. The thermal diffusivity of PI‐clay nanocomposite film increased at low clay content only when unmodified clay was used, where the clay morphology was a layered structure dispersed on a nanometer scale. Moreover, the thermal diffusivity could be enhanced by controlling the tensile stress induced by spontaneous shrinkage of the film during thermal imidization. These results demonstrated that the thermal diffusivity of PI‐clay nanocomposite films is significantly affected by the dispersion and/or arrangement states of the clay. © 2010 Wiley Periodicals, Inc.

Preparation and characterization of mono‐ and di‐d‐α‐tocopheryl polyethylene glycol 1000 succinate
Authors: Wang Jingyuan , Su Baogen , Xing Huabin , Yang Yiwen , Ren Qilong 
Published: September 2010

AbstractMono‐d‐α‐tocopheryl polyethylene glycol 1000 (TPGS 1000) and di‐TPGS 1000 were prepared from the synthesized TPGS 1000 mixture. The key separation step was performed by a Simulating Moving Bed chromatographic process. The chemical structures and molecular weight distrubution were characterized by 1H‐NMR and MALDI‐TOF mass spectroscopy. NMR and MALDI‐TOF MS data confirmed the occurrence of di‐TPGS. Both NMR and MALDI‐TOF MS results showed the degree of polymerization of the two esters and the molecular mass. The melting temperatures of the two polymers were investigated by DSC and the thermal decomposition temperatures have been determined by TGA. The melting temperatures of the two esters were 33 and 15°C, separately. And the two separated TPGS esters exhibited different thermal decomposition courses. © 2010 Wiley Periodicals, Inc.

Preparation and application of glycidyl methacrylate and methacrylic acid monomer mixture‐grafted poly(ethylene terephthalate) fibers for removal of methylene blue from aqueous solution
Authors: Arslan Metin 
Published: September 2010

AbstractA novel fibrous adsorbent that grafts glycidyl methacrylate (GMA) and methacrylic acid (MAA) monomer mixture onto poly(ethylene terephthalate) (PET) fibers was used for removal of methylene blue (MB) in aqueous solutions by a batch equilibration technique. The operation parameters investigated included, pH of solution, removal time, graft yield, dye concentration, and reaction temperature. The adsorption rate of MB is much higher on the MAA/GMA‐grafted PET fibers than on the ungrafted PET fibers. MB was removed 99% the initial dye concentration at 10 mg L−1 and 93% at 200 mg L−1 by monomers mixture‐grafted PET fibers. Pseudofirst order and pseudosecond order kinetic equations were used to examine the experimental data of different graft yield. It was found that the pseudosecond order kinetic equation described the data of dye adsorption on fibrous adsorbent very well. The experimental isotherms data were analyzed using Langmuir and Freundlich isotherm models. The data was that Freundlich isotherm model fits the data very well for the dyes on the fibers adsorbent. The dye adsorbed was easily desorbed by treating with acetic acid/methanol mixture (50% V/V) at room temperature. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010

Authors: Qureshi Ziyauddin S. , Deshmukh Krishna M. , Tambade Pawan J. , Dhake Kishor P. , Bhanage Bhalchandra M. 
Published: September 2010

AbstractThe nucleophilic substitution reaction of secondary alcohols and hydroamination of alkenes with amides, sulfonamides, carbamates, and amines using Amberlyst‐15 immobilized in [Bmim][BF4] (1‐butyl‐3‐methylimidazolium tetrafluoroborate) ionic liquid as an efficient recyclable reagent is described. The solvent effect is prominent in the reaction, and the desired substitution products are obtained in good to excellent yield. The protocol is advantageous due to the ease of handling of the reagents, the simple work‐up procedure, and the environmentally benign conditions that allow effective recyclability.

Authors: Martínez R. Fernando , Ávalos Martín , Babiano Reyes , Cintas Pedro , Jiménez José L. , Light Mark E. , Palacios Juan C. , Pérez Esther M. S. 
Published: September 2010

AbstractThis paper describes the synthesis and structural elucidation of 1,3‐oxazolidines derived from tris(hydroxymethyl)aminomethane (TRIS) and pyridine‐based aldehydes. Divergent results were obtained with other formylpyridines, such aspyridoxal, in which intramolecular hydrogen‐bonding largely stabilizes the iminic structure. The oxazolidines may undergo ring‐opening under acetylating conditions to afford imines through different mechanistic pathways, which have also been evaluated by DFT calculations.

AbstractObjectiveThe present report aimed to investigate the efficacy and tolerability of venlafaxine compared to methylphenidate in children and adolescents with Attention Deficit/Hyperactivity Disorder (ADHD).MethodsThis was a 6‐week, parallel group, randomized clinical trial. Thirty‐eight patients (27 boys and 11 girls) with a DSM‐IV‐TR diagnosis of ADHD were the study population of this trial. All study subjects were randomly assigned to receive treatment using capsules of venlafaxine at doses of 50–75 mg/day depending on weight (50 mg/day for <30 kg and 75 mg/day for >30 kg (group 1) or methylphenidate at a dose of 20–30 mg/day depending on weight (group 2) for a 6‐week double blind, randomized clinical trial. The principal measure of outcome was the Teacher and Parent Attention Deficit/Hyperactivity Disorder Rating Scale‐IV.ResultsNo significant differences were observed between the two groups on the Parent and Teacher Rating Scale scores (df = 1; F = 1.77; p = 0.19 and df = 1; F = 1.64; p = 0.20, respectively). Side effects of headaches and insomnia were observed more frequently in the methylphenidate group.ConclusionsThe results suggest that venlafaxine may be useful for the treatment of ADHD. In addition, a tolerable side‐effect profile is one of the advantages of venlafaxine in the treatment of ADHD. Copyright © 2010 John Wiley & Sons, Ltd.
Incorporation of a ridge–furrow–ridge rainwater harvesting system with mulches in high‐value plant production
Authors: Gosar Borut , Baričevič Dea 
Published: September 2010

ABSTRACTA new ridge–furrow–ridge rainwater harvesting (RFRRH) system with mulches has been promoted in agricultural production to improve economic potential for high‐value plant production. In this system, plastic mulch covered two ridges and the furrow between them, which serves as the rainwater‐harvesting zone. To evaluate this system, a two‐year field study was conducted to determine the effect of the RFRRH system with impermeable and permeable polyethylene (PE) mulch on soil water content, crop yield and production cost effectiveness in purple coneflower (Echinacea purpurea Moench.) production. The results of the study in 2007 and 2008 showed that the RFRRH system with impermeable and permeable PE mulch increases soil water content in dry periods at the beginning of plant growth, which can be one of the main reasons for higher yields in the mulch‐covered RFRRH system in comparison to the control (uncovered ridges). Moreover, higher yield and a reduction of labour improved production cost effectiveness in the RFRRH system with mulches in comparison to the control. The results confirm that the RFRRH system with mulches, in view of its rainwater‐collecting efficiency, simplicity and economic potential, can be applied in agricultural production.

Interpolation inequality of logarithmic type in abstract Besov spaces and an application to semilinear evolution equations
Authors: Matsumoto Toshitaka , Ogawa Takayoshi 
Published: September 2010

AbstractAn abstract version of Besov spaces is introduced by using the resolvent of nonnegative operators. Interpolation inequalities with respect to abstract Besov spaces and generalized Lorentz spaces are obtained. These inequalities provide a generalization of Sobolev inequalities of logarithmic type. Uniqueness problems to abstract semilinear evolution equations are also discussed (© 2010 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)
Indentation creep of polymers. I. Experimental
Authors: Quadrini Fabrizio , Squeo Erica Anna , Guglielmotti Alessandro 
Published: September 2010

AbstractAn experimental setup is proposed to perform creep indentation tests on thermoplastics. An infrared (IR) lamp is used to locally heat the sample, and a flat punch made of tungsten carbide is loaded on the sample surface. In order to show the capability of this test in evaluating the creep properties, creep indentation tests were carried out on PA66 and HDPE sheets at different temperatures and creep loads. Dynamic mechanical analyses (DMA) and uniaxial creep tests were also performed at different temperatures to have a comparison with the indentation test results. Master curves were built for all the test results, and time shift factors were extracted. In all cases, the logarithm values of the shift factor were linearly dependent on the temperature. Small differences were found in the shift factors of the DMA and uniaxial test results, whereas high differences were observed in the case of the indentation results due to the nonuniformity of the temperature in the sample. However, indentation creep compliance is strictly correlated with tensile creep compliance, and equivalent tensile creep properties can be extracted. POLYM. ENG.

Application of evolutionary algorithms to the definition of the optimal twin‐screw extruder configuration for starch cationization
Authors: Teixeira Cristina , Covas José A. , Berzin Françoise , Vergnes Bruno , Gaspar‐Cunha António 
Published: September 2010

AbstractThe twin‐screw configuration problem (TSCP) involves defining the location of a set of predefined screw elements of a corotating twin‐screw extruder configuration to optimize different, often conflicting, objectives. A multiobjective optimization methodology based on Evolutionary Algorithms was developed and applied to solve the TSCP. This methodology is used in starch cationization case studies, involving different screw elements and screw lengths. The results obtained, taking into consideration various conflicting objectives, such as minimizing the specific mechanical energy and maximizing output and reaction efficiency, have physical meaning and thus validate the methodology.

A fast and reliable procedure to determine the copolymer composition by GPC‐IR: Application to ethylene/propylene copolymers and comparison with 13C NMR
Authors: Suárez Inmaculada , Caballero Ma Joaquina , Coto Baudilio 
Published: September 2010

AbstractCopolymer properties depend on several parameters and one of the most important is its composition. Typically, this composition is determined by 13C nuclear magnetic resonance (13C NMR) analysis, which requires a long acquisition time and a fine adjustment of parameters to obtain the desired resolution. In this article, a method to determine the comonomer content of polymers based on the analysis from gel permeation chromatography (GPC) with an infrared (IR) detector is described. This GPC‐IR method is faster than NMR and can be carried out routinely during the GPC analysis. Three sets of ethylene/propylene copolymers synthesized using metallocene and Ziegler–Natta catalyst over a wide composition range. Linear and second order polynomial equations were checked for the relation between the ethylene percent and the IR CH3/CH ratio. Average deviation between GPC‐IR and NMR composition values was about 1% and allow conclude that this technique can be considered to be a goodalternative. POLYM. ENG.

Conformational analysis and design of cross‐strand disulfides in antiparallel β‐sheets
Authors: Indu S. , Kochat V. , Thakurela S. , Ramakrishnan C. , Varadarajan Raghavan 
Published: September 2010

AbstractCross‐strand disulfides bridge two cysteines in a registered pair of antiparallel β‐strands. A nonredundant data set comprising 5025 polypeptides containing 2311 disulfides was used to study cross‐strand disulfides. Seventy‐six cross‐strand disulfides were found of which 75 and 1 occurred at non‐hydrogen‐bonded (NHB) and hydrogen‐bonded (HB) registered pairs, respectively. Conformational analysis and modeling studies demonstrated that disulfide formation at HB pairs necessarily requires an extremely rare and positive χ1 value for at least one of the cysteine residues. Disulfides at HB positions also have more unfavorable steric repulsion with the main chain. Thirteen pairs of disulfides were introduced in NHB and HB pairs in four model proteins: leucine binding protein (LBP), leucine, isoleucine, valine binding protein (LIVBP), maltose binding protein (MBP), and Top7. All mutants LIVBP T247C V331C showed disulfide formation either on purification, or on treatment with oxidants. Protein stability in both oxidized and reduced states of all mutants was measured. Relative to wild type, LBP and MBP mutants were destabilized with respect to chemical denaturation, although the sole exposed NHB LBP mutant showed an increase of 3.1°C in T

m
. All Top7 mutants were characterized for stability through guanidinium thiocyanate chemical denaturation. Both exposed and two of the three buried NHB mutants were appreciably stabilized. All four HB Top7 mutants were destabilized (ΔΔG
0 = −3.3 to −6.7 kcal/mol). The data demonstrate that introduction of cross‐strand disulfides at exposed NHB pairs is a robust method of improving protein stability. All four exposed Top7 disulfide mutants showed mild redox activity. Proteins 2010. © 2010 Wiley‐Liss, Inc.
Computational chemistry and molecular simulations of phosphoric acid
Authors: Li Shuo , Fried J. R. , Sauer Jeremy , Colebrook John , Dudis Douglas S. 
Published: September 2010

AbstractQuantum mechanics (QM) calculations, molecular dynamics (MD) simulations using the condensed‐phase optimized molecular potentials for atomistic simulation studies (COMPASS) force field, and the atom‐centered density matrix propagation (ADMP) approach have been used to investigate properties of phosphoric acid (PA). QM using B3LYP/6‐31++G(d,p) density functional theory were used to calculate gas‐phase proton affinities and interaction energies of PA and its derivatives. Detailed single coordinate driving, followed by quadratic synchronous transit optimization was used to determine energy barriers for different proton transfer (PT) pathways. Determined energy barrier heights in ascending order are (unit: kJ/mol): H3O+→H3PO4 (0); H4P2O7→H3PO4 (2.61); H3PO4→H2PO (5.31); H4PO→H3PO4 (∼7.33); H3PO4→H4P2O7/H3PO4→H3PO4 (15.99); H4P2O7→H2O (28.61); H3PO4→H2O (47.14). The COMPASS force field was used to study condensed‐phase properties of PA. Good agreement between experimental data and MD results including density, radial distribution functions, and self‐diffusion coefficient at different temperatures provides validation of the COMPASS force field for PA. Finally, preliminary ADMP studies on a cluster of three PA molecules shows that the ADMP approach can reasonably describe the PT and self‐dissociation processes in PA. © 2010 Wiley Periodicals, Inc.

Accurate mass measurement by matrix‐assisted laser desorption/ionisation time‐of‐flight mass spectrometry. II. Measurement of negative radical ions using porphyrin and fullerene standard reference materials
Authors: Shao Zhecheng , Wyatt Mark F. , Stein Bridget K. , Brenton A. Gareth 
Published: September 2010

AbstractA method for the accurate mass measurement of negative radical ions by matrix‐assisted laser desorption/ionisation time‐of‐flight mass spectrometry (MALDI‐TOFMS) is described. This is an extension to our previously described method for the accurate mass measurement of positive radical ions (Griffiths NW, Wyatt MF, Kean SD, Graham AE, Stein BK, Brenton AG. Rapid Commun. Mass Spectrom. 2010; 24: 1629). The porphyrin standard reference materials (SRMs) developed for positive mode measurements cannot be observed in negative ion mode, so fullerene and fluorinated porphyrin compounds were identified as effective SRMs. The method is of immediate practical use for the accurate mass measurement of functionalised fullerenes, for which negative ion MALDI‐TOFMS is the principal mass spectrometry characterisation technique. This was demonstrated by the accurate mass measurement of six functionalised C60 compounds. Copyright © 2010 John Wiley & Sons, Ltd.

Published: September 2010

AbstractPeptide tagging is a useful tool to improve matrix‐assisted laser desorption/ionization tandem mass spectrometric (MALDI‐MS/MS) analysis. We present a new application of the use of the dansyl chloride (DNS‐Cl). DNS‐Cl is a specific primary amine reagent widely used in protein biochemistry. It adds a fluorescent dimethylaminonaphthalene moiety to the molecule. The evaluation of MALDI‐MS and MS/MS analyses of dansylated peptides shows that dansylation raises the ionization efficiency of the most hydrophilic species compared with the most hydrophobic ones. Consequently, higher Mascot scores and protein sequence coverage are obtained by combining MS and MS/MS data of native and tagged samples. The N‐terminal DNS‐Cl sulfonation improves the peptide fragmentation and promotes the generation of b‐fragments allowing better peptide sequencing. In addition, we set up a labeling protocol based on the microwave chemistry. Peptide dansylation proved to be a rapid and cheap method to improve the performance of liquid chromatography (LC)/MALDI‐MS/MS analysis at the proteomic scale in terms of peptide detection and sequence coverage.
