L’urbanisation profuse saisie par la longue durée. Le cas de la Bretagne
Authors: Le Couédic Daniel , Prigent Lionel 
Published: September 2015

L’acculturation en France du concept américain d’urban sprawladvint tardivement, au terme d’un cheminement cahoteux qui a fait de l’expression – comme de sa cadette, la périurbanisation – un épouvantail visant à bannir toute pratique considérée comme indûment centrifuge eu égard à la conception dominante de la ville durable. Cette culpabilisation fait généralement litière de la longue durée de l’occupation et du façonnage des territoires, qui leur confère pourtant de fortes particularités imposant la nuance. Le trajet et les raisons de cette dérive sont exposés, en préalable à une démonstration appuyée sur le cas singulier de la Bretagne, prouvant que l’usage inapproprié de l’expression comme du concept fait porter un opprobre largement injustifié sur « les villes invisibles » qui caractérisent désormais cette région.

Published: September 2015

AbstractThe notion of sediment‐transport capacity has been engrained in geomorphological and related literature for over 50 years, although its earliest roots date back explicitly to Gilbert in fluvial geomorphology in the 1870s and implicitly to eighteenth to nineteenth century developments in engineering. Despite cross fertilization between different process domains, there seem to have been independent inventions of the idea in aeolian geomorphology by Bagnold in the 1930s and in hillslope studies by Ellison in the 1940s. Here we review the invention and development of the idea of transport capacity in the fluvial, aeolian, coastal, hillslope, débris flow, and glacial process domains. As these various developments have occurred, different definitions have been used, which makes it both a difficult concept to test, and one that may lead to poor communications between those working in different domains of geomorphology. We argue that the original relation between the power of a flow and its ability to transport sediment can be challenged for three reasons. First, as sediment becomes entrained in a flow, the nature of the flow changes and so it is unreasonable to link the capacity of the water or wind only to the ability of the fluid to move sediment. Secondly, environmental sediment transport is complicated, and the range of processes involved in most movements means that simple relationships are unlikely to hold, not least because the movement of sediment often changes the substrate, which in turn affects the flow conditions. Thirdly, the inherently stochastic nature of sediment transport means that any capacity relationships do not scale either in time or in space. Consequently, new theories of sediment transport are needed to improve understanding and prediction and to guide measurement and management of all geomorphic systems.
Seismotectonics of southern Haiti: A new faulting model for the 12 January 2010M7.0 earthquake

Published: September 2015

AbstractThe prevailing consensus is that the 2010Mw7.0 Haiti earthquake left the Enriquillo‐Plantain Garden strike‐slip fault (EPGF) unruptured but broke unmapped blind north dipping thrusts. Using high‐resolution topography, aerial images, bathymetry, and geology, we identified previously unrecognized south dipping NW‐SE striking active thrusts in southern Haiti. One of them, Lamentin thrust, cuts across the crowded city of Carrefour, extends offshore into Port‐au‐Prince Bay, and connects at depth with the EPGF. We propose that both faults broke in 2010. The rupture likely initiated on the thrust and propagated further along the EPGF due to unclamping. This scenario is consistent with geodetic, seismological, and field data. The 2010 earthquake increased the stress toward failure on the unruptured segments of the EPGF and on neighboring thrusts, significantly increasing the seismic hazard in the Port‐au‐Prince urban area. The numerous active thrusts recognized in that area must be considered for future evaluation of the seismic hazard.
Noise‐driven cooperative dynamics between vegetation and topography in riparian zones
Authors: Vesipa R. , Camporeale C. , Ridolfi L. 
Published: September 2015

AbstractRiparian ecosystems exhibit complex biotic and abiotic dynamics, where the triad vegetation‐sediments‐stream determines the ecogeomorphological features of the river landscape. Random fluctuations of the water stage are a key trait of this triad, and a number of behaviors of the fluvial environment can be understood only taking into consideration the role of noise. In order to elucidate how randomness shape riparian transects, a stochastic model that takes into account the main links between vegetation, sediments, and the stream is adopted, emphasizing the capability of vegetation to alter the plot topography. A minimalistic approach is pursued, and the probability density function of vegetation biomass is analytically evaluated in any transect plot. This probability density function strongly depends on the vegetation‐topography feedback. We demonstrate how the vegetation‐induced modifications of the bed topography create more suitable conditions for the survival of vegetation in a stochastically dominated environment.
Experimental and Theoretical Investigations of the Existence of CuII, CuIII, and CuIV in Copper Corrolato Complexes

Published: September 2015

AbstractThe most common oxidation states of copper in stable complexes are +I and +II. CuIII complexes are often considered as intermediates in biological and homogeneous catalysis. More recently, CuIV species have been postulated as possible intermediates in oxidation catalysis. Despite the importance of these higher oxidation states of copper, spectroscopic data for these oxidation states remain scarce, with such information on CuIV complexes being non‐existent. We herein present the synthesis and characterization of three copper corrolato complexes. A combination of electrochemistry, UV/Vis/NIR/EPR spectroelectrochemistry, XANES measurements, and DFT calculations points to existence of three distinct redox states in these molecules for which the oxidation states +II, +III, and +IV can be invoked for the copper centers. The present results thus represent the first spectroscopic and theoretical investigation of a CuIV species, and describe a redox series where CuII, CuIII, and CuIV are discussed within the same molecular platform.

Published: September 2015

AbstractDespite significant progress in the clinical application of antibody drug conjugates (ADCs), novel cleavage strategies that provide improved selectivity are still needed. Herein is reported the first approach that uses near‐IR light to cleave a small molecule from a biomacromolecule, and its application to the problem of ADC linkage. The preparation of cyanine antibody conjugates, drug cleavage mediated by 690 nm light, and initial in vitro and in vivo evaluation is described. These studies provide the critical chemical underpinning from which to develop this near‐IR light cleavable linker strategy.

Comparison of the performance of masterbatch and liquid color concentrates for mass coloration of polypropylene
Authors: Haastrup Sonja , Yu Donghong , Broch Thomas , Larsen Kim Lambertsen 
Published: September 2015

AbstractThe properties of polypropylene (PP) mixed with masterbatch (MB) and liquid color concentrates (LCC), respectively, were compared by preparing samples of PP with MB and PP with LCC and neat PP as a reference material using 1–4 extrusion cycles. Two colors were examined, i.e., a white color consisting of pigment white 6, and a green color consisting of pigment white 6, pigment blue 15:3, and pigment green 7. The color difference between PP prepared with MB and LCC was determined and the mechanical, rheological, and crystalline properties of PP prepared with MB and LCC were found to be generic. The color of PP obtained from MB and LCC were comparable. Further, it was found that the tensile strength, the viscosity, and the crystal structure obtained were similar when using LCC instead of MB. The viscosity of the treated PP generally decreased with increasing extruder retention time due to thermal degradation. The tensile strength and the crystal structure were independent of increased extruder retention time. © 2015 Wiley Periodicals, Inc. Col Res Appl, 41, 484–492, 2016

Published: September 2015

AbstractMesoporous Co3O4 was prepared using a dual templating approach whereby mesopores inside SiO2 nanospheres, as well as the void spaces between the nanospheres, were used as templates. The effect of calcination temperature on the crystallinity, morphology, and textural parameters of the Co3O4 replica was investigated. The catalytic activity of Co3O4 for photochemical water oxidation in a [Ru(bpy)3]2+[S2O8]2− system was evaluated. The Co3O4 replica calcined at the lowest temperature (150 °C) exhibited the best performance as a result of the unique nanostructure and high surface area arising from the dual templating. The performance of Co3O4 with highest surface area was further examined in electrochemical water oxidation. Superior activity over high temperature counterpart and decent stability was observed. Furthermore, CoO with identical morphology was prepared from Co3O4 using an ethanol reduction method and a higher turnover‐frequency number for photochemical water oxidation was obtained.
Effect of Dopants on the Adsorption of Carbon Dioxide on Ceria Surfaces
Authors: Li Meijun , Tumuluri Uma , Wu Zili , Dai Sheng 
Published: September 2015

AbstractHigh‐surface‐area nanosized CeO2 and M‐doped CeO2 (M=Cu, La, Zr, and Mg) prepared by a surfactant‐templated method were tested for CO2 adsorption. Cu, La, and Zr are doped into the lattice of CeO2, whereas Mg is dispersed on the CeO2 surface. The doping of Cu and La into CeO2 leads to an increase of the CO2 adsorption capacity, whereas the doping of Zr has little or no effect. The addition of Mg causes a decrease of the CO2 adsorption capacity at a low Mg content and a gradual increase at a higher content. The CO2 adsorption capacity follows the sequence Cu‐CeO2>La‐CeO2>Zr‐CeO2≈CeO2>Mg‐CeO2 at low dopant contents, in line with the relative amount of defect sites in the samples. It is the defect sites on the surface, not in the bulk of CeO2, modified by the dopants that play the vital role in CO2 chemisorption. The role of surface oxygen vacancies is further supported by an in situ IR spectroscopic study of the surface chemistry during CO2 adsorption on the doped CeO2.

ABSTRACTObjectiveStudying physiologic underpinnings of loss‐of‐control (LOC) eating may inform its etiology and contribute to intervention efforts. We therefore examined temporal relationships between autonomic indices [heart rate (HR), heart rate variability (HRV)] and LOC‐eating in the natural environment.MethodFor two days, adolescents (n = 17, 14.77 ± 1.55 years, BMI‐Z 2.17 ± 0.48) with LOC‐eating reported on LOC using an electronic device while HR and HRV were assessed continuously using Holter monitoring.ResultsHigher HR and lower HRV in the 30‐minutes before eating were significantly associated with LOC‐eating overall (p's < 0.001) and at the within‐participants level (p's < 0.001), but not at the between‐participants level (p's > 0.44). Examined categorically, HR was significantly higher, and HRV significantly lower, prior to high‐LOC compared to low‐LOC episodes (p's < 0.001).DiscussionThis pilot study suggests that LOC‐eating may involve physiologic underpinnings. Additional research with larger samples is needed to further investigate this phenomenon. © 2015 Wiley Periodicals, Inc. (Int J Eat Disord 2016; 49:197–201).
A Comparative Study of the Redox‐­Induced Linkage Isomerization of Ruthenium and Osmium Complexes
Authors: Li Huifang , Zhang Lisheng , Ye Min , Fan Xiaolin 
Published: September 2015

AbstractA dispersion‐corrected DFT study on the redox‐induced linkage isomerization of a family of [M(bpy)2AL]2+ complexes {M = Ru, Os; bpy = 2,2‐bipyridine; AL = 2‐[(isopropylsulfinyl)methyl]pyridine (pySO), 2‐[2‐(isopropylsulfinyl)ethyl]pyridine (pyESO), 2‐[3‐(isopropylsulfinyl)propyl]pyridine (pyPSO)} was undertaken. The calculated results indicated that modification of the metal center or ancillary ligand could produce distinct electronic and photophysical properties of the complexes. In good agreement with experimental absorption spectrum results, a redshift in the absorption maximum was observed if the metal center of the complex was changed from ruthenium to osmium. More importantly, the relative thermodynamic stabilities of the two linkage isomers in these complexes could also be tuned by modifications to the metal center or ancillary ligand. It was found that the relative energies between the S‐ and O‐linked ruthenium sulfoxide complexes were smaller than those between the osmium sulfoxide isomers. Intrinsic reaction pathway results demonstrated that intramolecular S→O and O→S isomerization was easier in the ruthenium complexes than in the osmium complexes with the same coordinated ligands. Moreover, intramolecular isomerization was more favorable if the number of methylene units between the sulfoxide group and the pyridine ring in the ancillary ligand was increased.

Published: September 2015

AbstractGold‐coated magnetic nanoparticles (Au@MNPs) have attracted significant interest in electrochemistry in recent years. This is especially the case with their application as dispersible electrodes where modified Au@MNPs are dispersed into a solution, selectively bind to the analyte of interest and are then brought to an electrode via application of a magnetic field for measurement. This paper characterizes four types of Au@MNPs with different sizes, shapes, and method of synthesis as dispersible electrodes. The Au@MNPs were characterized by transmission electron microscopy and X‐ray photoelectron spectroscopy and scanning electron microscopy. In addition, the electrochemical behaviour of Au@MNPs was investigated using cyclic voltammetry. The four sorts of Au@MNPs were evaluated with regards to the three main features required in the dispersible electrodes approach, well‐defined morphology, well‐defined electrochemistry and fast response to a magnetic field. The Cubic‐Au@MNPs, which presents the simplest synthetic route, showed the best electrochemical stability and performance, responding quickly to a magnet and had a well defined shape.

Published: September 2015

AbstractPerovskite oxides have recently been proposed as promising redox intermediates for solar thermochemical splitting of H2O and CO2, offering the benefit of significantly reduced operating temperatures. We present a systematic experimental screening of doped lanthanum manganites within the composition space La1−x(Ca,Sr)xMn1−yAlyO3 and identify several promising redox materials. In particular, La0.6Sr0.4Mn0.6Al0.4O3 and La0.6Ca0.4Mn0.6Al0.4O3 boast a five‐ to thirteen‐fold improvement in the reduction extent compared to the state‐of‐the‐art material CeO2 in the temperature range 1200–1400 °C. The materials are shown to be capable of splitting CO2 into CO fuel when isothermally cycled between low‐pO2 and high‐pCO2 environments at 1240 °C and to approach full reoxidation in CO2 with temperature swings as low as 200 °C, with mass‐specific fuel yields up to ten times that of CeO2. The underlying material thermodynamics are investigated and used to explain the favorable redox behavior.

Patients and rats with cirrhosis and ascites have portal hypertension and circulatory dysfunction. Synthetic arginine vasopressin (AVP) receptor agonists able to induce systemic and mesenteric vasoconstriction have shown their usefulness in reducing portal pressure (PP) in this condition. We assessed the potential therapeutic value of a new V1
a‐AVP receptor partial agonist with a preferential splanchnic vasoconstrictor effect (FE 204038) in rats with cirrhosis and ascites. The hemodynamic effects of cumulative intravenous doses of FE 204038, terlipressin, or vehicle were investigated. Mean arterial pressure and PP were continuously recorded and cardiac output and systemic vascular resistance (SVR) assessed at 30‐minute intervals for 90 minutes. Urine volume, urine osmolality, and urinary excretion of sodium and creatinine were measured in basal conditions and following twice‐daily subcutaneous doses of FE 204038 or vehicle. PP, mean arterial pressure, cardiac output, SVR, and ascites volume were also measured after 6 days. The expression of an array of vasoactive genes was assessed in the thoracic aorta and the mesenteric circulation of control rats and rats with cirrhosis and ascites. FE 204038 dose‐dependently decreased PP, did not modify mean arterial pressure, and increased SVR. The effect of the V1a‐AVP receptor partial agonist on PP was associated with an improvement in urine volume and urinary excretion of sodium during the first day of treatment. SVR was higher and cardiac output and ascites volume were lower in rats with cirrhosis and ascites treated with FE 204038. V1a‐AVP receptor expression in rats with cirrhosis and ascites was markedly enhanced in the mesenteric circulation compared to the thoracic aorta. Conclusion: FE 204038 increases sodium excretion and reduces portal hypertension and ascites in experimental cirrhosis. V1a‐AVP receptor partial agonism could be a useful pharmacological treatment in decompensated patients with cirrhosis. (Hepatology 2016;63:207–216)
Kinetic characterization of substrate‐analogous inhibitors of tyrosinase

Published: September 2015

AbstractThe development of effective tyrosinase inhibitors has become increasingly important in the cosmetic, medicinal, and agricultural industries for application as antibrowning and depigmenting agents. The kinetic mechanisms of action of tyrosinase on monophenols and o‐diphenols are complex, particularly in the case of monophenols because of the lag period that occurs at the beginning of the reaction. When enzyme inhibitors are studied, the problem becomes more complicated because the lag period increases, which has led to erroneous identification of the type of inhibition that many compounds exert on the monophenolase activity and the inaccurate determination of their inhibition constants. When the degrees of inhibition of an inhibitor which is analogous to tyrosinase substrates are the same for both monophenolase and diphenolase activities, this means that the inhibitor binds to the same enzymatic species and so the inhibition constants should be similar for both activities. In this study, we demonstrate this typical behavior of substrate‐analogous inhibitors and propose a methodology for determining the type of inhibition and the inhibition constants for the monophenolase and diphenolase activities of the enzyme. Benzoic acid and cinnamic acid were used as inhibitors and the monophenol/o‐diphenol pairs l‐tyrosine/l‐dopa and α‐methyl‐l‐tyrosine/α‐methyl‐l‐dopa as substrates. © 2015 IUBMB Life, 67(10):757–767, 2015
