Un logement foncièrement solidaire : le modèle des community land trusts
Authors: Attard Jean-Philippe 
Published: June 2013

Inéquitables, parce qu’elles absorbent une partie de la richesse socialement produite, les plus-values foncières induisent aussi une ségrégation spatiale dans les zones tendues, en verrouillant l’accès du marché immobilier aux catégories de la population à revenu modeste. La taxation des plus-values demeure la réponse privilégiée par les pouvoirs publics, bien que ses résultats ne paraissent pas à la mesure de l’enjeu. Les organismes américains connus sous le nom de community land trusts ont opté pour une autre solution : une démarchandisation du foncier couplée à une restriction conventionnelle des droits du propriétaire sur son logement. Selon ce modèle, une limitation librement consentie des plus-values au moment des reventes garantit l’accessibilité permanente des unités de logements aux ménages à faible revenu. Avec près de trente ans d’exercice, leur bilan démontre l’efficacité d’un usage du foncier comme patrimoine social, vecteur de solidarité dans l’accès au logement.
« Intégration, piège à cons ! »

Published: June 2013

Fils d’un ouvrier algérien membre du FLN, Abdelaziz Gharbi est l’héritier, à sa manière, d’une histoire ouvrière profondément intriquée à celle du colonialisme. Sa trajectoire nous éclaire sur le racisme du monde scolaire, et sur les points aveugles d’une gauche et d’une extrême gauche trop longtemps indifférentes aux combats contre les violences policières et contre les discriminations de toutes sortes. Ancien militant du Mouvement immigration banlieue (MIB), aujourd’hui directeur d’une régie de quartier à Aubervilliers, il ne cesse de rappeler la violence des inégalités économiques alors que la longue histoire des trahisons du Parti socialiste se poursuit. Sa voix précieuse tranche avec celle, bruyante, des experts et des politiques qui se pressent au chevet du « problème des banlieues » depuis plus de vingt ans.

Abstract
An emerging body of evidence suggests a pivotal role of CD3+ T cells in mediating early ischemia reperfusion injury (IRI). However, the precise phenotype of T cells involved and the mechanisms underlying such T cell–mediated immune responses in IRI, as well as their clinical relevance, are poorly understood. In this study, we investigated early immunological events in a model of partial warm hepatic IRI in genetically targeted mice to study the precise pathomechanistic role of RORγt+ T cells. We found that unconventional CD27−γδTCR+ and CD4−CD8− double-negative T cells are the major RORγt-expressing effector cells in hepatic IRI that play a mechanistic role by being the main source of IRI-mediating IL-17A. We further show that unconventional IRI-mediating T cells are contingent on RORγt, as highlighted by the fact that a genetic deficiency for RORγt, or its therapeutic antagonization via digoxin, is protective against hepatic IRI. Therefore, identification of CD27−γδTCR+ and CD4−CD8− double-negative T cells as the major source of IL-17A via RORγt in hepatic IRI opens new therapeutic options to improve liver transplantation outcomes.

Abstract
Abs that bind the functional envelope glycoprotein (Env) spike are considered critical for a broadly effective prophylactic HIV-1 vaccine. The difficulty in eliciting such Abs by vaccination is partially attributed to the immunodominance of hydrophilic, surface-exposed variable protein regions of Env. However, little is known about the potential for competition between B cells that recognize distinct and distal epitopes on Env during protein subunit vaccination. In this study, we address this basic question at the level of Ab-secreting cells and serum IgG using a pair of isogenic soluble Env trimers, designated wildtype and gV3, which differ only in their potential to activate B cell responses against the highly immunogenic V3 region of Env. Immunization of mice with gV3 resulted in a markedly lower Ag-specific response compared with that induced by wildtype Env and could be explained by a loss of V3-directed reactivities. There was no redistribution of the response to other regions of Env in gV3-inoculated mice, suggesting that the epitope-specific Ab-secreting cell responses measured after boost are independently regulated rather than dictated by direct or indirect competition between B cells recognizing different structural elements of Env. This information is relevant for ongoing efforts in Env immunogen design to focus responses on conserved neutralizing determinants and for our general understanding of B cell responses to large-protein Ags that display numerous B cell epitopes.
Diagnostic Efficacy of Panoramic Radiography in Detection of Osteoporosis in Post-Menopausal Women with Low Bone Mineral Density
Authors: Bhatnagar Sunanda , Krishnamurthy Vasavi , Pagare Sandeep S. 
Published: June 2013

Objective:
The aim of the study was to evaluate panoramic radiograph, a commonly taken dental radiograph as a screening tool to detect early osseous changes (normal, mildly or severely eroded) of the mandibular inferior cortex and measure the mandibular cortical width (CW) in post-menopausal women and correlate it with the bone mineral density (BMD) measured by the ultrasound bone sonometer at the mid-shaft tibia region.

Materials and Methods:
The study included females between 45 years and 65 years of age in their post-menopausal stage (no menstruation for at least 6-12 months). Mandibular indices (mandibular CW and mandibular cortical shape) were evaluated from panoramic radiographs. The BMD assessment was carried out at the mid-shaft tibia region, exactly half-way between the heel and the knee joint perpendicular to the direction of the bone, using an ultrasound bone sonometer. It is a non-invasive device designed for quantitative measurement of the velocity of ultrasound waves as speed of sound in m/s, capable of measuring bone density at one or more skeletal sites. Using 1994 WHO criteria the study subjects were categorized as Group 1: Normal, Group 2: Osteopenia, Group 3: Osteoporosis. (WHO T score for tibia BMD can be used as a standard).

Results:
The diagnostic efficacy of the panoramic radiograph in detecting osseous changes in post-menopausal women with low BMD was shown to have 96% specificity and 60% sensitivity with mandibular cortical shape and 58% specificity and 73% sensitivity with mandibular CW measurement. Factorial ANOVA analysis carried out indicated a significant correlation of BMD classification with mandibular cortical shape (F = 29.0, P < 0.001, partial eta squared [η2] =0.85), a non-significant correlation with mandibular CW, (F = 1.6, P = 0.23, η2 = 0.86), and a more significant correlation with combined cortical shape and width (F = 3.3, P < 0.05, η2 = 0.70).

Conclusion:
The study concludes that the combined mandibular cortical findings (P < 0.05) and mandibular cortical shape erosion alone (P < 0.001) on panoramic radiograph are effective indicators of osteoporosis in post-menopausal women.

Published: June 2013

AbstractLi2MnO3 is the parent compound of the well‐studied Li‐rich Mn‐based cathode materials xLi2MnO3·(1‐x)LiMO2 for high‐energy‐density Li‐ion batteries. Li2MnO3 has a very high theoretical capacity of 458 mA h g−1 for extracting 2 Li. However, the delithiation and lithiation behaviors and the corresponding structure evolution mechanism in both Li2MnO3 and Li‐rich Mn‐based cathode materials are still not very clear. In this research, the atomic structures of Li2MnO3 before and after partial delithiation and re‐lithiation are observed with spherical aberration‐corrected scanning transmission electron microscopy (STEM). All atoms in Li2MnO3 can be visualized directly in annular bright‐field images. It is confirmed accordingly that the lithium can be extracted from the LiMn2 planes and some manganese atoms can migrate into the Li layer after electrochemical delithiation. In addition, the manganese atoms can move reversibly in the (001) plane when ca. 18.6% lithium is extracted and 12.4% lithium is re‐inserted. LiMnO2 domains are also observed in some areas in Li1.63MnO3 at the first cycle. As for the position and occupancy of oxygen, no significant difference is found between Li1.63MnO3 and Li2MnO3.
Exploring tire crumb as activator for sulfur vulcanization

Published: June 2013

ABSTRACTIn this study, a new approach to reduce the environmental effects of end of life and waste rubber and, at the same time, to minimize the ZnO levels in rubber compounds is presented. The use of tire crumb as activator for sulfur vulcanization is investigated. To give an insight into the reaction mechanism, the approach is tested using model compound vulcanization (MCV) with squalene as a model molecule. The results showed that the use of the new recipe does not alter the kinetics of the vulcanization and that the cross‐link degree achieved is nearly equivalent to using ZnO. However, in real rubber mixtures [natural rubber (NR), butadiene rubber (BR), and styrene–butadiene rubber (SBR)], there is not a correlation between the promising characteristics seen in MCV and the actual performance of tire crumb. The extent of cross‐linking is significantly lower and the mechanical properties are worst in most of the cases. In spite of that, the results found in MCV suggest that further research should be carried out in order to take advantage of the features observed by improving or facilitating the interaction between the chemicals present in the tire crumb and the ingredients added to the rubber matrix. © 2013 Wiley Periodicals, Inc.

Morphology and properties of highly talc‐ and CaCO3‐filled poly(vinyl alcohol) composites prepared by melt processing
Authors: Wang Bin , Wang Qi , Li Li 
Published: June 2013

ABSTRACTHighly filled poly(vinyl alcohol) (PVA) composites, PVA/talc and PVA/CaCO3, were successfully prepared through melt‐processing technology without use of coupling agents or compatibilizers. Morphology analysis showed that both of the two fillers well dispersed in PVA matrix. Differently, the flaky talc obviously oriented, while the particulate CaCO3 was randomly scattered in PVA matrix. Rheological analysis showed that the two filled systems exhibited a common shear‐thinning phenomenon, confirming their pseudoplastic nature. Compared with the particulate CaCO3, the flaky talc exhibited a closer arrangement in the composite, resulting in a lower threshold filler content to form the network structure. Therefore, PVA/talc composite showed higher melt viscosity and lower extrudate‐swell ratio. The orientation of the flaky talc particles in the system also resulted in the higher melting and heat‐deflection temperatures, as well as a greater reinforcement effect on the composite, but a lower elongation at break. © 2013 Wiley Periodicals, Inc.

Published: June 2013

AbstractTwo analogous multipolar chromophores (1 and 2) that contained 2,3,8‐trisubstituted indenoquinoxaline moieties have been synthesized and characterized for their two‐photon absorption properties, both in the femtosecond and nanosecond time regimes. We demonstrated that their multi‐branched framework structures, which incorporated appropriately functionalized indenoquinoxaline units, afforded large molecular nonlinear absorptivities within the studied spectroscopic range. Effective optical‐power‐limiting and stabilization behaviors in the nanosecond regime of dye molecule (2) were also investigated and the results indicated that such a structural motif could be a useful approach to the molecular design of highly active two‐photon systems for quick‐response and related broadband optical‐suppressing applications, in particular for confronting laser pulses of a long duration.

These could represent the future of buildings in Germany: homes that generate more renewable energy than they consume, thanks to sustainable planning and construction coupled with efficient, responsible use. But legislation has been lagging behind the PlusEnergy standard. The new Energieausweis+ certificate for PlusEnergy residential buildings was designed as an add‐on to the energy performance certificate for residential buildings, given the option provided in § 17 (4) of the German Building Energy Conservation Ordinance to include additional information [18]. The Energieausweis+ certificate for PlusEnergy residential buildings is a tool which can be deployed to assess PlusEnergy designs in terms of all user‐ and planning‐dependent energy flows.

AbstractAs a part of an investigation on the potential risks of radiofrequency identification (RFID) on human health, we studied whether exposure to 915 MHz RFID in rats significantly affected the secretory function of the thyroid system. A reverberation chamber was used as a whole‐body exposure system. Male Sprague–Dawley rats were exposed for 8 h per day, 5 days per week, for a duration of 2, 4, 8, or 16 weeks. The estimated whole‐body average specific absorption rate (SAR) varied from 3.2 to 4.6 W/kg depending on the age/mass of the animals for the field of the 915 MHz RFID reader. Plasma levels of triiodothyronine (T3), thyroxine (T4), and thyroid‐stimulating hormone (TSH) were evaluated via enzyme‐linked immunosorbent assay. Morphological changes in the thyroid gland were then analyzed. No changes in T3, T4, or TSH were observed over time between the sham‐ and RFID‐exposed groups. We suggest that subchronic exposure to 915 MHz RFID at a SAR of 4 W/kg does not cause significant effects on thyroid secretory function.

Multi‐phosphorylation of the Intrinsically Disordered Unique Domain of c‐Src Studied by In‐Cell and Real‐Time NMR Spectroscopy

Published: June 2013

AbstractIntrinsically disordered regions (IDRs) are preferred sites for post‐translational modifications essential for regulating protein function. The enhanced local mobility of IDRs facilitates their observation by NMR spectroscopy in vivo. Phosphorylation events can occur at multiple sites and respond dynamically to changes in kinase–phosphatase networks. Here we used real‐time NMR spectroscopy to study the effect of kinases and phosphatases present in Xenopus oocytes and egg extracts on the phosphorylation state of the “unique domain” of c‐Src. We followed the phosphorylation of S17 in oocytes, and of S17, S69, and S75 in egg extracts by NMR spectroscopy, MS, and western blotting. Addition of specific kinase inhibitors showed that S75 and S69 are phosphorylated by CDKs (cyclin‐dependent kinases) differently from Cdk1. Moreover, although PKA (cAMP‐dependent protein kinase) can phosphorylate S17 in vitro, this was not the major S17 kinase in egg extracts. Changes in PKA activity affected the phosphorylation levels of CDK‐dependent sites, thus suggesting indirect effects of kinase–phosphatase networks. This study provides a proof‐of‐concept of the use of real‐time in vivo NMR spectroscopy to characterize kinase/phosphatase effects on intrinsically disordered regulatory domains.

Published: June 2013

AbstractA facile and efficient method for the synthesis of isoindoline, indane, and dihydroisobenzofuran derivatives has been developed through the application of a halogen‐bridged iridium(III) complex to the [2+2+2] cycloaddition of α,ω‐diynes with alkynes. The cycloaddition tolerates a broad range of substitution groups, such as alcohol, alkyl, ether, and halogen, and the chemistry can be extended to prepare the corresponding borylated fused arenes. The reaction shows that hindered starting materials are also good partners, which provide the desired fused arenes in good yields.

Published: June 2013

AbstractLavandin essential oil has been encapsulated in poly‐(ϵ‐caprolactone) (MW: 4000 g mol–1) by means of the particles from gas saturated solutions (PGSS) process. The influence of process conditions, i.e., pre‐expansion temperature and pressure, and oil/polymer mass ratio, on the morphology of particles and the efficiency of encapsulation has been analyzed. Spherical particles with particle sizes of 100–700 μm were obtained, with increasing particle sizes and more agglomeration as the oil/polymer ratio was increased. The efficiency of encapsulation was increased by conditions that favored a fast solidification of the polymer shell, including high pre‐expansion pressures, reaching efficiencies up to 50 % with oil loads up to 120 mg oil/g particles.

Published: June 2013

AbstractThe drying process of organic solid waste is investigated, based on an experimental study involving its drying kinetics. The experiments were conducted in a thin‐layer fixed‐bed dryer under various operational conditions. The problem of selecting the best fit for solid waste moisture content as a function of time is addressed as well, using artificial neural network (ANN) models and four well‐known drying kinetics correlations commonly applied to biological materials. According to the statistical analysis employed, the simulations showed good results for the ANN, and the Overhults model provided optimum agreement with experimental data among all other models evaluated. Empirical correlations between the Overhults model parameters and the drying operational conditions using nonlinear regression techniques were determined.
Nanocrystalline Zeolite Tetraethylammonium‐Beta Membrane for Preferential Sorption and Transport of CO2 over N2

Published: June 2013

AbstractCO2/N2 gas separation was performed over a nanocrystalline zeolite tetraethylammonium (TEA)‐beta membrane prepared on a stainless‐steel porous disc by repeated hydrothermal crystallization. Two to three consecutive hydrothermal syntheses were required to form a membrane comprised of a continuous and compact layer of zeolite beta nanocrystals on the support. The membrane TEA‐BEA3 obtained by three consecutive syntheses, in which the membrane from two consecutive syntheses was used as support, exhibited the highest structural order. When the separation experiment was performed over this membrane without applying any external applied pressure, 100 % selectivity of CO2 over N2 was observed. The separation was driven by differences in chemical potentials of the molecules generated only by the adsorption‐desorption behavior of the gases into the membrane. The novel zeolite TEA‐beta membrane provided promising results for the separation of small gas molecules due to the combined influence of diffusion and sorption selectivity.
CFD Study on the Local Mass Transfer Efficiency in the Gas Phase of Structured Packing
Authors: Zhang Y.‐L. , Zhu H.‐M. , Yin Q.‐X. 
Published: June 2013

AbstractVisualization of local mass transfer coefficients over the dry surface of corrugated‐sheet structured packing is essential for optimizing the existing geometry of structured packing and for improving mass transfer efficiency to develop new structured packing. The local flow patterns between packing sheets and the gas‐phase mass transfer coefficient at each point over the surface are illustrated by employing a wall‐surface reaction model. Different turbulence models are utilized, i.e., a standard κ‐ϵ model and three different low‐Re‐κ‐ϵ models. The numerical calculation results with the Lam‐Bremhorst low‐Re‐κ‐ϵ turbulence model is found to agree well with experimental data. There are three similar regions with enhanced mass transfer efficiency in each mass transfer unit cell of structured packing.
