Quand le piéton défie la ville : traverser la chaussée à Mexico
Authors: Pérez López Ruth 
Published: May 2016

À Mexico, la configuration de l’espace urbain ne répond pas aux besoins des piétons. Lors de son parcours en ville, le piéton doit surmonter différentes barrières physiques. Au moment de traverser la chaussée, il doit, en plus, se protéger des véhicules. Dans ce sens, la traversée incarne un obstacle majeur pour le piéton et représente le lieu par excellence où s’expriment et matérialisent les relations entre piétons et conducteurs. À travers une approche socio-anthropologique basée sur une étude empirique, il s’agit d’appréhender les formes d’occupation d’un espace public souvent disputé, en rendant compte d’une dimension de la vie urbaine peu analysée à Mexico.
Environnement urbain et marchabilité : l’exemple du quartier des Aubiers à Bordeaux
Authors: Pagnac-Baudry Héloïse 
Published: May 2016

Le quartier des Aubiers, pôle multimodal de la métropole bordelaise, est articulé autour du tramway et anime l’espace public. Notre recherche montre que l’arrivée du tramway dans le quartier des Aubiers a contribué au développement d’une mobilité piétonne importante vers l’ensemble de la métropole bordelaise. La mise en relation entre l’environnement urbain et la marchabilité permet de mettre en exergue combien la configuration des espaces entraîne une pluralité des pratiques de la marche. Les itinéraires empruntés dans le quartier se révèlent être fort différents selon l’identité du marcheur : passant ou résident. En mutation constante, le site des Aubiers témoigne des nouvelles perspectives qu’apporte la prise en compte de la marche pour repenser l’espace public.
Apprendre à regarder la ville dans l’obscurité : les « entre-deux » du paysage urbain nocturne
Authors: Bertin Sylvain , Paquette Sylvain 
Published: May 2016

Entre deux univers, de lumière et de ténèbres, l’éclaireur décide de ce que l’on éclaire ou de ce qu’on laisse dans l’ombre. Souvent opposée au jour, la nuit est ancrée dans une opposition qui nous a longtemps fait nier son existence. Dans un contexte d’expansion de la lumière artificielle et d’interrogation de la qualité des cadres de vie urbains, peut-on encore fermer les yeux sur la nuit ? Dans le cadre d’une plus vaste recherche sur le paysage montréalais nocturne, nous présentons une recension des approches et des questionnements sur la manière dont nous regardons et planifions la ville la nuit pour dévoiler les enjeux de paysages encore méconnus.
Enhancement of photoelectrochemical activity of SnS thin-film photoelectrodes using TiO2, Nb2O5, and Ta2O5 metal oxide layers
Authors: Vequizo Junie Jhon M. , Yokoyama Masanori , Ichimura Masaya , Yamakata Akira 
Published: May 2016

Abstract
Tin sulfide (SnS) fine photoelectrodes fabricated by three-step pulsed electrodeposition were active for H2 evolution. The incident-photon-conversion-efficiency increases from 900 nm and offers a good fit with the absorption spectrum. The activity was enhanced by 3.4, 3.0, and 1.8 times compared to bare SnS by loading Nb2O5, TiO2, and Ta2O5, respectively. Nb2O5 was most efficient because its conduction band is low enough to facilitate effective electron transfer from SnS; it also has sufficiently high potential for H2 evolution. The overall activity is determined by the competitive interfacial electron transfer between SnS/metal-oxide and metal-oxide/water. Therefore, constructing appropriate heterojunctions is necessary for further improving photoelectrochemical systems.

Authors: Chee Chin Soon , Chang Khai Meng , Loke Mun Fai , Angela Loo Voon Pei , Subrayan Visvaraja 
Published: May 2016

Aim/hypothesis:The aim of our study was to characterize the human salivary proteome and determine the changes in protein expression in two different stages of diabetic retinopathy with type-2 diabetes mellitus: (1) with non-proliferative diabetic retinopathy (NPDR) and (2) with proliferative diabetic retinopathy (PDR). Type-2 diabetes mellitus without diabetic retinopathy (XDR) was designated as control.Method:In this study, 45 saliva samples were collected (15 samples from XDR control group, 15 samples from NPDR disease group and 15 samples from PDR disease group). Salivary proteins were extracted, reduced, alkylated, trypsin digested and labeled with an isobaric tag for relative and absolute quantitation (iTRAQ) before being analyzed by an Orbitrap fusion tribrid mass spectrometer. Protein annotation, fold change calculation and statistical analysis were interrogated by Proteome Discoverer. Biological pathway analysis was performed by Ingenuity Pathway Analysis. Data are available via ProteomeXchange with identifiersPXD003723–PX003725.Results:A total of 315 proteins were identified from the salivary proteome and 119 proteins were found to be differentially expressed. The differentially expressed proteins from the NPDR disease group and the PDR disease group were assigned to respective canonical pathways indicating increased Liver X receptor/Retinoid X receptor (LXR/RXR) activation, Farnesoid X receptor/Retinoid X receptor (FXR/RXR) activation, acute phase response signaling, sucrose degradation V and regulation of actin-based motility by Rho in the PDR disease group compared to the NPDR disease group.Conclusions/Interpretation:Progression from non-proliferative to proliferative retinopathy in type-2 diabetic patients is a complex multi-mechanism and systemic process. Furthermore, saliva was shown to be a feasible alternative sample source for diabetic retinopathy biomarkers.

Correlation of Teacher Education Graduates’ Academic Performance, Licensure Examination Performance, Type of Work and Waiting Time for Job Search
Authors: Dangan Shirley D. 
Published: May 2016

Graduates’ performance in licensure examination and their employability are key performance indicators in quality assurance. The quality of teacher education curriculum offered by universities is measured by the graduates’ performance in the licensure examination for teachers and their employability in teaching. A teacher education graduate must have a valid professional license to be employed as teacher. This study determined the relationships of the teacher education graduates’ academic performance, rating in the licensure examination for teachers, type of work and waiting time for job search. A descriptive-correlational research design was used to study the direction and magnitude of the relationship between the variables involved in the study. One hundred sixty-four teacher education graduates of Palawan State University Cuyo Campus were involved as respondents. Descriptive survey and documentary analysis technique were employed in gathering data. The statistical analysis of data revealed significant relationships between the teacher education graduates’ academic performance, rating in the licensure examination for teachers, type of work and waiting time for job search. Licensure tests increase the costs of entering an occupation and a failure rate lengthens the waiting time for job search and creates uncertainty about obtaining employment.

Heat flow along the Costa Rica Seismogenesis Project drilling transect: Implications for hydrothermal and seismic processes
Authors: Hass Bridget , Harris Robert N. 
Published: May 2016

AbstractHeat flow analysis of the Costa Rica convergent margin is carried out for seven sites drilled during Integrated Ocean Drilling Program (IODP) Expeditions 334 and 344 as part of the Costa Rica Seismogenesis Project (CRISP). These expeditions are designed to better understand erosional subduction zones. Heat flow measurements were made to improve estimates of the thermal structure of this erosive margin and are located on the incoming plate, toe, lower, middle, and upper slopes of the margin. Heat flow values corrected for the effects of seafloor bathymetry and sedimentation are on average 15% higher than uncorrected values and range from approximately 158–200 mW/m2 on the incoming plate to values of approximately 50 mW/m2 on the middle and upper slopes of the margin. These values are consistent with previous estimates of heat flow showing a landward decrease in heat flow consistent with subduction of the Cocos plate. Preferred thermal models of the shallow subduction zone successfully predicting observed values of heat flow incorporate fluid flow within the upper oceanic aquifer have an uppermost permeability of 10−9.5 m2 and a plate boundary effective coefficient of friction of 0.06. These models suggest that temperatures on the subduction thrust reach 100°C at distances between 30 and 35 km landward of the deformation front. The updip limit of seismicity, as defined by aftershocks events of ML 1–4 recorded following the Mw 6.9 Quepos earthquake, occurs at 25 km landward of the deformation front at temperatures cooler than the 100–150°C typically predicted.
Parallele chemische Proteinsynthese auf der Oberfläche zur schnellen Analyse der Phosphoregulierung von SH3‐Domänen
Authors: Zitterbart Robert , Seitz Oliver 
Published: May 2016

AbstractMangelnde Verfügbarkeit erschwert die Analyse posttranslational modifizierter Proteindomänen, denn rekombinante Methoden vermitteln nur selten die gewünschte Ortsspezifität. Die Totalsynthese ermöglicht zwar eine nahezu vollkommene Kontrolle über posttranslationale und andere Modifikationen, jedoch bleiben chemische Methoden auf kürzere Peptide beschränkt. Zur Lösung dieses Problems präsentieren wir hier eine Methode, die a) Immobilisierung N‐terminaler Thio‐Peptidhydrazide über Hydrazonverknüpfung, b) native chemische Ligation auf der Oberfläche mit selbstgereinigten Peptidthioestern c) radikalisch induzierte Entschwefelung und d) einen oberflächenbasierten Fluoreszenzbindungs‐Assay zur funktionellen Charakterisierung kombiniert. Die Methode wurde zur schnellen Untersuchung von 20 SH3‐Domänen verwendet. Die Analyse lässt schließen, dass Tyrosinphosphorylierung der SH3‐Domänen in Abl‐Kinasen als Schalter fungiert, der sowohl einen Verlust als auch einen Gewinn an Affinität für prolinreiche Liganden induzieren kann.
The Role of Dynamics and Allostery in the Inhibition of the eIF4E/eIF4G Translation Initiation Factor Complex
Authors: Salvi Nicola , Papadopoulos Evangelos , Blackledge Martin , Wagner Gerhard 
Published: May 2016

AbstractLack of regulation of the interaction between the eIF4E/eIF4G subunits of the translation initiation factor complex eIF4F is a hallmark of cancer. The inhibitor 4EGI‐1 binds to eIF4E, thereby preventing association with eIF4G through an allosteric mechanism. NMR spectroscopy and MD simulations were used to obtain a mechanistic description of the role of correlated dynamics in this allosteric regulation. We show that binding of 4EGI‐1 perturbs native correlated motions and increases correlated fluctuations in part of the eIF4G binding site.
A Formal Enantiospecific Synthesis of 7,20‐Diisocyanoadociane
Authors: Roosen Philipp C. , Vanderwal Christopher D. 
Published: May 2016

Abstract7,20‐Diisocyanoadociane (DICA) is a potent antimalarial isocyanoterpene endowed with a fascinating tetracyclic structure composed of fused chair cyclohexanes. We report a highly stereocontrolled synthesis of a late‐stage intermediate, the “Corey dione”, from which DICA has been made previously. This formal synthesis features a rapid buildup of much of the complexity of the target through a sequence of enone tandem vicinal difunctionalization, Friedel–Crafts cyclodehydration, and sequential stereocontrolled reductions. Most importantly, this success establishes the broader feasibility of our previously developed general synthesis approach to the isocyanoterpene family and provides a blueprint for a very direct synthesis of DICA and related natural products.
Model‐based optimization of the feeding policy of a fluidized bed bioreactor for mercury uptake by immobilized Pseudomonas putida cells
Authors: Şcoban Andreea Georgiana , Maria Gheorghe 
Published: May 2016

AbstractA model‐based analysis of a three‐phase continuously operated fluidized bed bioreactor is developed in order to determine the multi‐objective optimal feeding policy of the immobilized biomass used for removing mercury ions from wastewater. The analysis is focus on finding the optimal feeding policy of alginate porous beads of known particle size containing immobilized biomass (Pseudomonas putida bacteria) to minimize the biomass consumption, while keeping a quasi‐constant high conversion. The extended bioreactor model is accounting for the biomass growth, biodegradation, and its partial leakage and washout. Bioreactor dynamics prediction has been generated by using a simple Michaelis–Menten kinetic model adopted from literature. The resulted optimal feeding policy of the bioreactor points out the importance of the adoption of an extended and adequate process/reactor model able to solve engineering operation problems by quickly adjusting the feeding conditions according to the time‐varying characteristics of the biomass culture and to the limited possibilities to control the process during the wastewater residence time in the bioreactor. © 2016 Curtin University of Technology and John Wiley & Sons, Ltd.
Decomposition of Fluorinated Graphene under Heat Treatment
Authors: Plšek Jan , Drogowska Karolina Anna , Valeš Václav , Ek Weis Johan , Kalbac Martin 
Published: May 2016

AbstractFluorination modifies the electronic properties of graphene, and thus it can be used to provide material with on‐demand properties. However, the thermal stability of fluorinated graphene is crucial for any application in electronic devices. Herein, X‐ray photoelectron spectroscopy (XPS), temperature‐programmed desorption (TPD), and Raman spectroscopy were used to address the impact of the thermal treatment on fluorinated graphene. The annealing, at up to 700 K, caused gradual loss of fluorine and carbon, as was demonstrated by XPS. This loss was associated with broad desorption of CO and HF species, as monitored by TPD. The minor single desorption peak of CF species at 670 K is suggested to rationalize defect formation in the fluorinated graphene layer during the heating. However, fluorine removal from graphene was not complete, as some fraction of strongly bonded fluorine can persist despite heating to 1000 K. The role of intercalated H2O and OH species in the defluorination process is emphasised.
