Biotraitement en réacteur de polluants organiques contenus dans les sols argileux
Authors: Hau Jean-Michel , Morin Dominique 
Published: June 2015

Static bioremediation of clayey soils polluted by contaminating organics is very difficult because, most of the time, both reagents and reaction products mass transfer between the solids particles and the aqueous or gaseous phases are limited. Dynamic treatment, by means of agitated and aerated bioreactors, applied to the remediation of sludge or soils represents an attractive alternative process route.
Les sols argileux pollués par des molécules organiques posent problème pour tout traitement de dépollution biologique en voie statique, car, par nature, les transferts des réactifs et des produits de réaction entre la phase solide et la phase liquide ou gazeuse sont fortement limités. Le concept du traitement dynamique en réacteur agité permet d'envisager de pallier ces obstacles et donc d'envisager favorablement de traiter ces sols.
Les contraintes financières pour les collectivités locales françaises dans la gestion des déchets
Authors: Cabanes Alain 
Published: June 2015

Waste precollection, collection and treatment is more and more expensive. As the quality of collection and treatment get better, its cost is increasing. ln 2002, according to the objectives of the law, a local authority will attain 20% to 25% of recycling, 20% of composting and 55% to 65% of incineration with energy recovery. The operation cost will be around 1.300 FF/ waste ton including TVA: 220 FF.
La précollecte, la collecte et le traitement des déchets coûtent de plus en plus cher. Au fur et à mesure que la qualité de la collecte et du traitement s'améliore, son coût augmente. A l'échéance 2002, une collectivité conforme aux objectifs atteindra de 20 à 25 % de recyclage, 20 % de compostage, et 55 à 60 % d'incinération avec production d'énergie. Le coût global TTC de l'opération se situera à 1 300 F environ, dont 220 F de TVA.

The BRGM group applies its know-how, inherited from mineral processing, to waste treatment and environment. As an application in association with Framatome the build up of a grinding and magnetic separation processfor a stainless/graphite waste from nuclear industry is presented. After a set-up at pilot scale this process is used at industrial scale on a contamined medium. This example shows the interest of using mechanical preparation and magnetic sorting techniques to separate wastes components.
Le groupe BRGM met au service du traitement des déchets et de l'environnement ses savoir-faire hérités du traitement des matières premières minérales. Un cas concret est présenté : la mise en oeuvre, avec la société Framatome d'un procédé de broyage et de séparation magnétique de déchets inox - graphite de l'industrie nucléaire qui, après une phase pilote de mise au point, est utilisé à l'échelle industrielle en milieu hostile. Cet exemple montre l'intérêt de l'utilisation de techniques de préparations mécaniques et de tris magnétiques pour séparer des constituants de déchets.

With the new development of the Beaulieu District in Caen (France), the city of Caen awarded to Soletanche Bachy support works for underground quarries.In place of traditional material used for this kind of works, a new mortar, based on MSWI bottom ash and specially developed by Inertec, was monitoring panel, set up by the supervisory agencies.In application of French and European normalization works on long term behavior determination (X30- 407 methodology), an assessment study has been started by Inertec, in collaboration with Ademe (French Agency for Environment). The first results of the study, presented in this paper, are indicating that bottom ash mortar in the quarries will have a negligible impact on underground water quality.These first results will have to be compared to on site results during several years, in order to have a reliable validation.
Dans le cadre de l'aménagement de la ZAC Beaulieu, la ville de Caen (France) a confié à Solétanche Bachy des travaux de confortement de carrières souterraines. En remplacement des matériaux d'extraction habituellement utilisés dans ce type de chantier, un nouveau mortier, développé tout spécialement par Inertec à partir de mâchefers d'incinération d'ordures ménagères, a été injecté en carrières par pompage.Cette opération innovante a été soumise pendant toute sa durée à des contrôles très stricts, à la fois par un plan d'assurance qualité interne et par une commission de suivi, regroupant différents organismes de surveillance (Drire, Services Municipaux,...).En application des travaux français et européens de normalisation sur la détermination du comportement à long terme (norme expérimentale X30-407), une étude d'impact a été entreprise par Inertec, en collaboration avec l'Ademe. Les premiers résultats de l'étude, présentés ici, semblent montrer que la présence du mortier de mâchefers stabilisés dans les carrières aura un impact négligeable sur la qualité des eaux souterraines.Ces premiers résultats seront à comparer aux données recueillies sur site pendant plusieurs années, de façon à établir une validation fiable.
Le logiciel Traces : un outil d'aide à la gestion des risques liés aux sites et sols pollués
Authors: Viet-Long Duong , Formisyn Pascal , Bourgois Jacques , Abadie Jean-Marie 
Published: June 2015

The two last centuries of uncontrolled industrialization have produced large amounts of brownfields, wastes dumps, landfills... in most of occidental countries. These sites, having used or produced hazardous or toxic substances, are potentially contaminated sites. The last official inventory of the Ministry of Environment in France has established 896 polluted sites for an estimated 200,000 potentially contaminated sites from the professionals of this domain.The problem related to these sites is the capability of the pollution to migrate from the soil to the surface water, the groundwater, and the air and finally to have an impact on living organisms (human, fauna, flora). Questions which are to be solved are then the extent and impact of the contamination and the alternatives to remediate it.The scientific and technical complexity added to the lack of (public or private) money make it hard to correctly manage these sites.For this purpose, a decision support system was developed in order to provide a rational, standardized and easy approach of potentially contaminated sites, and was called Traces (Tool for Risk Assessment from Chemical Exposure to Soils).
Deux siècles d'industrialisation souvent incontrôlée ont apporté quantités de friches industrielles, de dépôts de déchets, de décharges, etc dans la plupart des pays industrialisés. Ces sites ayant utilisé, produit ou généré des produits dangereux ou toxiques constituent autant de lieux potentiellement pollués. Le dernier recensement du ministère de l'Environnement fait état de 896 sites pollués sur un gisement estimé par les professionnels de la dépollution des sols à plus de 200000 potentiellement pollués. Le problème lié aux sites pollués réside dans la capacité de la pollution à migrer dans le sol et à contaminer l'eau de surface par ruissellement, l'eau souterraine par infiltration, l'air par volatilisation : il y a donc un impact potentiel sur les organismes vivants (homme, faune, flore). Comment déterminer l'étendue et l'impact exacts de la contamination et comment conjurer cette contamination devient une vraie question. La complexité technique et scientifique du problème ainsi que le manque de moyens financiers (publics ou privés) rendent la gestion de ces sites difficile (traitement dans l'urgence). Afin de faciliter ce traitement, un outil d'aide à la gestion des sites potentiellement pollués a été développé permettant une approche rationnelle, standardisée et simple des sites et sols pollués. Le logiciel Traces (Tool for Risk Assessment from Chemical Exposure to Soils) a été mis au point pour répondre à cette problématique.
“PLEASE PASS THE SALT” – AN ETHNOARCHAEOLOGICAL STUDY OF SALT AND SALT FERMENTED FISH PRODUCTION, USE AND TRADE IN NORTHEAST THAILAND.
Authors: Yankowski Andrea , Kerdsap Puangtip , Chang Dr. Nigel 
Published: June 2015

Northeast Thailand is known for salt production, both today and in the past. Prehistoric salt sites are found throughout the region and ethnographic and historical data demonstrates the importance of salt as a commodity as well as for preserving and fermenting fish. This paper explores the archaeology and cultural history of salt and salt fermented fish products in Northeast Thailand and the Greater Mekong Delta region. Using archaeological, historical and ethnographic data, it addresses how the foods we eat and our preparation methods can be deeply rooted in our cultural history and identity, and discusses the ways in which they can be studied in the archaeological record to learn about the past.
Analytical Solution for Elliptical Cloaks Based on The Frequency Selective Surface
Authors: Ghasemi Mizuji E. , Abdolali A. , Derafshi I. 
Published: June 2015

In this paper the elliptical dielectric cylinder which is covered with FSS cloak is considered. Frequency selective surface cloak which Alu named it mantle cloak is one of the recent techniques for cloaking. In this method an appropriate FSS can act as cloaking device for suppressing the scattering of object in the desired frequency. With using this method the dimension of the cloaks is extremely reduced. By this proposed structure, the RCS of elliptical cylinder is reduced about 10-20 dB and designed cloak has an appropriate performance. The analytical solution for the wave in each layer is presented and with using simulation, the electric field and the scattering pattern has been drawn.
Degradation of zinc in saline solutions, plasma, and whole blood
Authors: Törne Karin , Larsson Mariann , Norlin Anna , Weissenrieder Jonas 
Published: June 2015

AbstractThe initial degradation of zinc has been investigated through exposures to simulated and real body fluids of increasing complexity: phosphate buffered saline (PBS), Ringer's saline solution, human plasma, and whole blood. Real body fluids were used to close the electrolyte gap between simulated and in vivo environment. Polarization of zinc in whole blood show a passive response not present in other electrolytes. The analysis shows a decrease in corrosion rate with time for plasma and whole blood and an increase for PBS and Ringer's. During exposure to plasma and whole blood a bi‐layered corrosion product with poor adherence was formed over a uniformly corroding surface. The corrosion products comprise a mixture of inorganic material and biomolecules. Samples degrading in PBS were prone to localized corrosion and formed thick porous corrosion products of primarily zinc phosphates while in Ringer's solution a gel like layer of zinc carbonate was formed over an interface with shallow pits. The use of whole blood or plasma as electrolytes for short term in vitro evaluation of potential biodegradable metals may provide an improved understanding of the behavior in vivo, while Ringer's solution is preferred over PBS for long term degradation studies of zinc. © 2015 Wiley Periodicals, Inc.

The task of time in retirement
Authors: EKERDT DAVID J. , KOSS CATHERYN 
Published: June 2015

ABSTRACTRetirees' encounter with time has long interested social scientists, especially the negotiation of such an open-ended status. Pursuing theoretical suggestions that daily activities anchor a narrative of self-identity, this project examined the coherence of retirees' representations of their time use. Information is drawn from interviews with 30 retirees in the Midwestern United States of America who were invited to discuss their daily lives and activities. The retirees valued time sovereignty and accounted for their time use by describing schedules of activities in some detail. Daily time was not presented as improvised but rather as structured into routines. Recurring behaviours flowed from situations and structures in which people were implicated, such as body care and living with others. Even in replies to a specific question about the preceding day, people slipped into language about what they typically do. Retirees' ready narratives about routines were also accounts of who they are not. Our findings suggest, first, that daily routines are instrumental for retirees in economising thought and behaviour. Second, the assertion of a routine is an assurance that one's life is ordered and proceeds with purpose, thus solving the task of time. Third, routines can be a means to signal conformity with ideals of active ageing.
Gelation-driven Dynamic Systemic Resolution: in situ Generation and Self-Selection of an Organogelator
Authors: Hu Lei , Zhang Yang , Ramström Olof 
Published: June 2015

AbstractAn organogelator was produced and identified from a dynamic imine system, resolved and amplified by selective gelation. The formation of the organogel was monitored in situ by 1H NMR, showing the existence of multiple reversible reactions operating simultaneously and the redistribution of the involved species during gelation. The formed organogelator proved effective with a range of organic solvents, including DMSO, toluene and longer, linear alcohols.
Intracellular microRNA profiles form in the Xenopus laevis oocyte that may contribute to asymmetric cell division

Published: June 2015

AbstractAsymmetric distribution of fate determinants within cells is an essential biological strategy to prepare them for asymmetric division. In this work we measure the intracellular distribution of 12 maternal microRNAs (miRNA) along the animal-vegetal axis of the Xenopus laevis oocyte using qPCR tomography. We find the miRNAs have distinct intracellular profiles that resemble two out of the three profiles we previously observed for mRNAs. Our results suggest that miRNAs in addition to proteins and mRNAs may have asymmetric distribution within the oocyte and may contribute to asymmetric cell division as cell fate determinants.
Glass ceiling and sticky floors: hurdles for Mauritian working women
Authors: Tandrayen-Ragoobur Verena , Pydayya Rajeev 
Published: June 2015

Purpose– The purpose of this paper is to analyse the gender wage differential at different points of the wage distribution. It investigates the existence of glass ceilings and sticky floors in the Mauritian labour market. There is no previous empirical work studying gender inequality in the labour market for the small island economy of Mauritius.Design/methodology/approach– To investigate whether wage differentials are higher at the top or bottom ends of the wage distribution, the authors examine the wage disparities across different quantiles of the wage distribution. The gender wage disparities are assessed using quantile regression and decomposition techniques at the 10th, 25th, 50th, 75th and 90th quantiles. Survey data from the Continuous Multi-Purpose Household Survey from 2006 to 2013 is used.Findings– The results reveal that sticky floors are more pronounced than glass ceilings over the years. Further, for the years 2008, 2010 and 2012, it is noted that at the 75th quantiles, the gender wage differentials started to rise showing glass ceiling effects. The combination of both sticky floors and glass ceilings are characterised by the unexplained factors providing evidence for gender discrimination in the Mauritian labour market.Originality/value– This is the first study analysing the glass ceilings or sticky floors in the Mauritian labour market. Though the research is limited to Mauritius, the latter being a small island economy can serve as a case study for other island economies and also for the African continent.
Does compliance with the German Corporate Governance Code pay off?
Authors: Kaspereit Thomas , Lopatta Kerstin , Zimmermann Jochen 
Published: June 2015

Purpose
– This paper aims to empirically investigate the relationship between the level of compliance with the German Corporate Governance Code’s (GCGC) recommendations and the implied cost of equity capital (ICC). German listed companies are required by law to annually disclose their compliance with the recommendations of the GCGC. Whether the GCGC achieves its aim to promote the trust of stakeholders in the management and supervision is still an open question.

Design/methodology/approach
– ICC is regressed on a score that captures compliance with the GCGC and several control variables. The dataset covers the period of 2003-2012 with declarations of compliance from 447 companies. ICC is chosen as an outcome variable, as it captures general investment risk as well as risk arising from asymmetric information and mistrust of investors in management.

Findings
– The results of the empirical analysis demonstrate that a higher level of GCGC compliance is associated with lower ICC.

Research limitations/implications
– It is expected that the results of this study will strengthen acceptance of the GCGC and empirically support the work of the government commission that is responsible for it. It has not been analyzed yet whether the firms cite good reasons why they do not adhere to certain items.

Originality/value
– This empirical analysis is the first to provide statistically reliable evidence on how compliance with the GCGC affects ICC and whether the work of the government commission reflects good corporate governance as perceived by capital markets.
Talent and student private rented sector bottlenecks: a preliminary UK investigation
Authors: Huston Simon , Jadevicius Arvydas , Minaei Negin 
Published: June 2015

Purpose– The purpose of this paper is to sketch the UK housing backdrop, review the student private rented sector (PRS) and assess the experience of post-graduate university student tenants in the PRS.Design/methodology/approach– A literature review puts the issues of student-PRS responsiveness into context and helps to untangle some UK housing issues. The private sector’s size, growth and performance is assessed by reviewing secondary data. In-depth interviews were then conducted at a regional university campus.Findings– The study confirms accumulating evidence of an unbalanced UK housing market. The study identified four main PRS issues: first, rapid university expansion without accompanying residential construction has sparked rampant PRS growth with, second, quality issues, third, in tight letting market conditions, rented agent service levels fell and fourth, part of the problem is complex PRS management procedures.Research limitations/implications– The research has three noteworthy limitations. First, the macroeconomic analysis integrated secondary research without independent modelling. Second, the views of letting agents, university property managers, planning officers or landlords were not canvassed. Finally, the pilot interviews were geographically restricted.Practical implications– When they expand, universities, local authorities and industry players need to give due consideration to plan for, design and develop quality student accommodation. Over-reliance on the PRS without informed oversight and coordination could undermine student experience and erode long-term UK competitiveness.Social implications– The lack of quality student rented accommodation mirrors a general housing malaise around affordability, polarisation and sustainable “dwelling”. Standards and professionalism in the rented sector is part of the overall quality mix to attract global talent.Originality/value– The preliminary investigation uses mixed-methods to investigate PRS service delivery. It illustrates the interplay between professional property management and wider issues of metropolitan productivity, sustainability and resilience.
An assessment of oral cancer curricula in dental hygiene programmes: implications for cancer control
Authors: Thacker KK , Kaste LM , Homsi KD , LeHew CW 
Published: June 2015

AbstractPurposeTo assess oral cancer prevention and early detection curricula in Illinois associate‐degree dental hygiene programmes and highlight global health applications.MethodsAn email invitation was sent to each Illinois associate‐degree granting dental hygiene programme's oral cancer contact to participate in a survey via a SurveyMonkey™ link to a 21‐item questionnaire. Questions elicited background information on each programme and inquired about curriculum and methods used for teaching oral cancer prevention and early detection.ResultsEight of the 12 (67%) programmes responded. Three (37.5%) reported having a specific oral cancer curriculum. Five (62.5%) require students to perform examinations for signs and symptoms of oral cancer at each clinic visit. Variations exist across the programmes in the number of patients each student sees annually and the number of oral cancer examinations each student performs before graduation. Seven programmes (87.5%) conduct early detection screening in community settings. All programmes included risk assessment associated with tobacco. All other risk factors measured were treated inconsistently.ConclusionSignificant differences in training and experience were reported across Illinois dental hygiene programmes. Training is neither standardized nor uniformly comprehensive. Students' preparation for delivering prevention and early detection services to their patients could be strengthened to ensure competence including reflection of risk factors and behaviours in a global context. Regular review of curricular guidelines and programme content would help dental hygienists meet the expectations of the Crete Declaration on Oral Cancer Prevention.
