What can immigrants do for non-migrant relatives in their home country who need healthcare they cannot afford? To answer this question, we first examine four existing methods that can be found in the existing literature: mobility, remittances, workers’ health insurance and diasporic health insurance. In the second part of the paper, we discuss an innovative strategy called “transnational health insurance” (THI). These insurance schemes are set up by immigrants in cooperation with a multitude of actors including health insurance companies in destination countries and healthcare providers in countries origin. THIs offer health coverage to non-migrant relatives in the home country based on a premium paid directly by immigrants to the insurance company in their country of residence. Analyzing the creation and implementation of Belgian-Congolese THIs, we discuss the strengths and weaknesses of these schemes in responding to the needs of both immigrants and their non-migrant relatives. The article concludes with a discussion on the specificities of THIs as hybrid forms of remittances. [less ▲]

Landscape infrastructures are numerous. They can be hedgerows, woodlands or wildflower strips. They are known to provide ecosystem services such as reducing soil erosion and nutrient leaching or support biodiversity conservation. They may also help to biologically control pests. But conclusions of research papers are not unanimous about the positive effect of wildflower strips to control pests in fields. The cause may be the type of flower mixes sown in fields. In this context, the concept of functional diversity may be useful to constitute flower mixes that better enhance biological control. [less ▲]

In 2001, an interdisciplinary team, composed of 22 scientists, developed a methodology aiming at analyzing problems of water resources in Vallée du Draa (Morocco). The issue was studied through 4 points of view: (i) disponibility of water, according to a hydrogeological evaluation of the region, (ii) mechanic, technic and physic access to water, taking into account political, cultural and financial sovereign, allowing to guarantee access to water at the levels of nation, region, locality, family and individual, (iii) quality of water and its evolution – rainy, superficial, underground, residual water, water for agriculture and breeding, (IV) efficiency and profitability of water. Water needs appeared to be higher that available resources. Rainy and superficial water supplies appeared to be weak and poorly distributed in time. Strong seasonal change in the level of phreatic layer suggested an overexploitation of aquifers. Valleys were characterized by sedimentation of irrigation canals, exploitation of underground water, remoteness and dispersion of agricultural areas. Social and gender equitability in water distribution and access were poor, leading to desertion and emigration. Water quality was considered as poor. It can be concluded that palm groves allows populations to maintain in an area. Sustainability of the system depend on water access, water quality and profitability. Survival of the system depends on irrigation, rights to water access, and presence of water of quality. [less ▲]

Afin de mesurer au mieux un paramètre, il faut préalablement connaître son identité. Concernant la métrologie de la pollution olfactive, toute la difficulté réside dans la particularité de cette pollution. En effet, bien qu’associée à la pollution de l’air par les molécules volatiles qui la génèrent, elle en diffère par son effet sensoriel. Il va de soi que la pollution olfactive n’a de sens que par son odeur. Chaque individu a son propre odorat et dès lors sa propre interprétation de l’odeur. C’est cette subjectivité qui rend cette pollution si délicate à qualifier et à quantifier et qui la distingue de la pollution de l’air. De plus, contrairement à d’autres pollutions sensorielles de type sonore ou visuel, l’élément porteur ’est pas dans ce cas une grandeur physique telle que la longueur d’onde électromagnétique ou la variation de pression mais une grandeur physico-chimique particulière dont la mesure est beaucoup plus complexe. Un dictionnaire de langue française définit l’odeur comme « une émanation volatile, caractéristique de certains corps et susceptible de provoquer chez l’homme ou chez un animal des sensations dues à l’excitation d’organes spécialisés ». Cette définition de l’odeur met notamment en jeu deux disciplines : la chimie et la physiologie. En effet un chimiste pourrait présenter l’odeur comme un ensemble de molécules aux propriétés spécifiques qui inhalées par un individu génère une réaction, il s’intéresserait dès lors aux odorants alors qu’un physiologiste parlerait plutôt du stimulus induit par ces odorants et des mécanismes qui le provoquent au niveau des organes. Le traitement de l’information olfactive par le cerveau, la perception olfactive, conduit à plusieurs types de sensation. En effet, l’odeur perçue a trois grandes particularités : l’intensité, la qualité (ou la nature de l’odeur) et la tonalité hédonique ou affective (agrément/désagrément). A ces trois dimensions, il faut ajouter le caractère temporel du stimulus, dimension très utilisée dans le cadre de la pollution olfactive. [less ▲]

The life goal of constructing Transnational Artistic Careers might open up opportunities for some migrant women who wish to participate in today’s global cities’ cultural domains. In this context, this contribution is based on my first observations in the city of Brussels in which, I encountered complex dynamics of Latin American and Gender identities constructions, both among my participants and myself. Drawing from Transnational (Glick-Schiller and Levitt 2004) and Cosmopolitan Perspectives (Glick-Schiller, Tsypylma et al. 2011) I traced in a life-course fashion, the Transnational Artistic Careers (Martiniello and Rea 2011) that served the women invoked in my analysis, to develop cosmopolitan competencies. Such competencies, I argue became their tool to find recognition as well as to express, a sense of belonging that extended beyond ethnic categorizations deployed by more hegemonic perspectives. They described themselves as the entrepreneurs of their artistic careers while they developed through them alternative representations of how they wanted to be known by “others”. Concluding, by aiming to discover different forms of Transnational Artistic Careers this paper focused on the agency by which these women resisted and empowered themselves against racialized, and ethnicized global hierarchies of power.

Sludges collected from Oupeye WWTP (MS=80%), Grosses Battes WWTP (MS=85.5%), and Embourg WWTP (MS=88%) in Belgium and presenting different properties were used. The influence of the sawdust/sludge ratio on convective drying was investigated in a fixed bed. X-ray tomography was used to assess changes in volume, exchange surface and void fraction. Results showed that the average drying rates were 0.062 (Oupeye), 0.079 g/s (Grosses Battes) and 0.042 g/s (Embourg) respectively, using raw sludges. For sawdust/sludge mixtures with the mass ratio of 4/6, the average drying rates of sludges were improved (Oupeye: 0.092 g/s, Grosses Battes: 0.106 g/s, Embourg: 0.049 g/s). [less ▲]

The aurora at Saturn represents a direct manifestation of the interaction between the planet’s surrounding space environment and its upper atmosphere. Our understanding of this interaction has greatly improved over the past decade, as a result of both in-situ and remote sensing of the aurora by Cassini, as well as through Earth-based observations. On Earth, the interaction is dominated by the connection between the magnetosphere and the Solar Wind, with opening and closing of magnetic field lines leading to sporadic aurora that are strongly controlled by changes in the solar wind. On Jupiter, internal plasma sources combine with a rotationally-dominated magnetosphere to produce intense currents associated with the breakdown in co-rotation in the magnetosphere, producing powerful and continuous aurora. Investigations into Saturn’s aurora have shown that the overall morphology changes dramatically with the arrival of compressions in the solar wind, suggesting a strong interaction with the solar wind at Earth. However, the varying rotation rate of Saturn’s magnetosphere, first identified by measurements of Saturn’s radio emission, can also be measured in many aspects of the auroral emission. This in turn suggests a degree of rotational control within the aurora. As such, the better we understanding the relative strength of these influences on the aurora of Saturn, the more we can understand how the magnetosphere interacts the planet and how, in turn, the planet drives changes in the magnetosphere. Here, we will present observations of the auroral emission directly produced by particles precipitating into Saturn’s atmosphere (radio emission), the resultant atmospheric auroral excitation this produces within of atomic hydrogen (UV and visible emission) and molecular hydrogen (UV emission), as well as thermal emission from both ions produced through auroral ionization and neutral species heated within the auroral region (IR emission). These observations show a wide variety of different auroral features ranging from the rotational pole, though the main auroral emission and down to latitudes where Saturn’s atmosphere interacts with Enceladus. Observations at these different wavelength, when compared and contrasted, reveal details about the particle precipitation process that drive them, as well as the affect these currents have on the surrounding neutral atmosphere. In-situ measurements by Cassini of the particles and magnetic field above the polar region allow us to measure and understand the field-aligned currents that produce the aurora. In comparing these currents with the auroral emission at the foot of these field lines, it is possible to understand the magnetospheric origin for Saturn’s auroral emission, as well as understanding the two-way interaction between the atmosphere and magnetosphere that is driven though the currents that produce this aurora.

« Les CoP (Communautés de Pratiques) sont des groupes de personnes qui partagent une préoccupation ou une passion pour quelque chose et qui apprennent à le faire mieux en interagissant régulièrement. ». Dans le monde hospitalier comme dans celui des entreprises, il est capital de compter des professionnels performants et efficaces. La mise en place de communautés de pratique peut aider les organisations à rencontrer cet objectif. Certaines Communautés de Pratique émergent spontanément, évoluent naturellement et se réorientent ou meurent tout simplement au terme de leurs projets. D’autres voient le jour grâce à l’intervention d’une personne extérieure. L’origine de la CoP n’interfère pas sur la qualité du travail effectué en son sein mais l’organisation et les rôles y sont répartis différemment.

Istanbul and its 12 million inhabitants borders the Marmara Sea, a submarine pull-apart basin related to the North Anatolian Fault (NAF), a major strike slip fault that ruptures in M>7 earthquakes. Constraining the recurrence rate of M>7 earthquakes that threaten the megacity is problematic because the active faults are submarine. For assessing past submarine earthquake ruptures of the Cinarcik Fault Segment located just south of Istanbul, we studied two sedimentary cores and identified seismoturbidites related to historical ruptures. Earthquake related turbidites are identified in both cores, based on their distinctive sedimentological and geochemical signatures. The seismoturbidites recorded in one of the core named Klg04 are inferred to record only mass wasting events related to the rupture on the Cinarcik Segment because of its specific geomorphological location. To constrain the seismoturbidites chronology, we combine short-lived radionuclide, radiocarbon and paleoinclination data. The first four seismoturbidites recorded match the 1894, 1509, 14th century and 989 historical earthquakes. The obtained age model allows us to discuss past historical rupture scenario across the Marmara Sea. The fact that the 1766 earthquakes are not recorded is further discussed based on new macroseismic intensity data and sedimentary records East of the Cinarcik Basin. [less ▲]

Depuis plusieurs années, des recherches sont effectuées afin de substituer une partie du clinker, composant principal du ciment Portland, dont la production libère des quantités importantes de CO2, par les laitiers de haut-fourneau, les cendres volantes et/ou les fillers calcaires. Dans le projet CEMCALC I, la possibilité de remplacer une partie de ce clinker par du laitier de haut fourneau et du filler calcaire a été étudiée. Plusieurs compositions de ciment ternaire (clinker, laitier, filler) ont été étudiées, notamment vis-à-vis des attaques sulfatiques à 5°C. Des mesures de module d’élasticité dynamique, de vitesse sonore, ainsi que des analyses DRX et des observations au MEB ont été réalisées. Les ciments montrant la meilleure résistance aux attaques sulfatiques à 5°C sont ceux qui contiennent le plus de laitier. Les phases responsables de la dégradation des éprouvettes sont les croûtes secondaires de gypse, ainsi qu’une solution solide composée d’ettringite et de thaumasite. [less ▲]

In this paper the problem of modal identification of time-varying system is investigated. To do so, a technique based on the sifting process of the Hilbert Vibration Decomposition (HVD) method is presented. The key idea is to estimate the instantaneous frequency of the dominant mode, to extract its corresponding component by demodulation of the recorded signals and then to iterate with the subsequent dominant mode. In the case of multiple recorded signals, a source separation method is used as a preprocessing step to facilitate the identification of the instantaneous frequency for the following demodulation step. To illustrate the method, an experimental set-up consisting in a beam travelled by a non negligible mass is considered. The whole structure is randomly excited during the travel of the mass and some responses on the beam are recorded. [less ▲]

This study examines the share and allocation of household expenditure in health financing, as presented by the National Health Account figures. These figures are based on a national survey carried out in 2010 among 11,000 households, 2,200 people living with HIV/AIDS, 183 institutions, 42 mutual funds, 18 companies and using the balance sheets of 1,300 companies. Total household health expenditure per capita per year amounted to U.S. $ 4.50. Routine health expenditure is covered by the households (40%) and international cooperation (45%) through direct payment without cost sharing (93.7%). A hospital stay is warranted in case of nutritional deficiencies (34%), malaria (12%) and mental disorders (10%). 82% of outpatient care is related to malaria (71%) and mental disorders (12.5 %). In conclusion, the observation that 71.58% of hospitals expenditure, 96.49% of ambulatory care centres expenditure, 98.48% of medical and diagnosis laboratories expenditure, 72.42% of pharmacies expenditures come from households’ out of pocket expenses calls for the establishment of solidarity mechanisms in the health sector. Outpatient malaria care consumes as much as 71% of household expenditure, and we therefore need to strengthen prevention, treatment and focus on monitoring progress. The fact that nutritional deficiencies are the leading cause of people seeking hospital care suggests that efforts are needed to improve their living conditions of households. Mental disorders are the third leading cause of hospital recourse and this pathology should therefore be included in the minimum and supplementary package of activities. [less ▲]

The problem of designing control chart is formulated as a multi-objective optimization problem with the adjusted average time to signal as the statistical objective and the expected cost per hour as the economic objective. Then we try to find the Pareto-optimal designs in which the two objectives are minimized simultaneously by using the elitist non-dominated sorting genetic algorithm method. Through an illustrative example, the advantages of the proposed approach is shown by providing a list of viable optimal solutions and graphical representations, thereby bolding the advantage of flexibility and adaptability.

Several types of physical systems are characterized by quantum wave func- tions with multifractal properties. In the quantum chaos field, they cor- respond to pseudointegrable systems, with properties intermediate between integrability and chaos. In condensed matter, they include electrons in a disordered potential at the Anderson metal-insulator transition. This multi- fractality leads to particular transport properties and appears in conjunction with specific types of spectral statistics. In parallel, progress in experimental techniques allows to observe finer and finer properties of the wavefunctions of quantum or wave systems, as well as to perform experiments with un- precedented control on the dynamics of the systems studied. In this context, this talk will discuss the robustness of multifractality in presence of footnote- size perturbations. We expose two scenarios for the breakdown of quantum multifractality under the effect of such perturbations. In the first scenario, multifractality survives below a certain scale of the quantum fluctuations. In the other one, the fluctuations of the wave functions are changed at every scale and each multifractal dimension smoothly goes to the ergodic value. We use as generic examples a one-dimensional dynamical system and the three- dimensional Anderson model at the metal-insulator transition, and show that for different types of perturbation the destruction of multifractal properties always follows one of these two ways. Our results thus suggest that quantum multifractality breakdown is universal and obeys one of these two scenarios depending on the perturbation. We also discuss the experimental implica- tions.

A mixed integer linear programming model for a two-dimensional capacitated vehicle routing problem (2L-CVRP) with sequence based loading and axle weight restrictions is provided. To the authors’ knowledge, it is the first time that axle weight restrictions are incorporated in a VRP. Axle weight limits impose a great challenge for transportation companies. Trucks with overloaded axles represent a significant threat for traffic safety and may cause serious damage to the road surface. Transporters face high fines when violating these limits. The problem is based on a real-world problem from a Belgian logistics service provider. The demand of the customers consists of europallets. Pallets can be placed in two horizontal rows inside the vehicle. No vertical stacking is allowed. The center of gravity of the pallets inside the vehicle is calculated to determine the axle weights. Results of the model are compared to results of a 2L-CVRP with sequence based loading without axle weight restrictions. Numerical experiments demonstrate that the model performs adequately and that the integration of axle weight constraints in vehicle routing models is necessary for a feasible route planning.

Partendo dal presupposto che la costruzione della soggettività individuale sia un processo composito e dinamico, questo intervento mira a metterne in evidenza i sostrati materiali, cioè quei fattori che agiscono direttamente sulla corporeità. In particolare, viene considerata la materialità delle pratiche alimentari e culinarie come luogo della definizione stratificata del sé. Tali pratiche dialogano con una pluralità di discorsi che sfumano i confini dei corpi individuali e li rendono permeabili agli effetti delle rappresentazioni collettive e delle appartenenze che queste determinano. L’intervento focalizzerà sulla storia di Bâhirah, una giovane donna di origine marocchina residente nella provincia di Milano. La sue pratiche del quotidiano, indagate con il metodo dell’osservazione partecipante e grazie ad interviste semi-strutturate, forniscono un esempio delle dinamiche enunciate sopra. L’importanza del cibo nella storia di questa donna è determinata da diversi fattori, tra i quali la malattia di una delle sue figlie, affetta da diabete mellito 1. Le disfunzioni corporee che caratterizzano questa patologia, determinano la necessità, da un lato, di un controllo minuzioso degli alimenti ingeriti (dunque incorporati) e degli elementi biologici che li compongono; dall’altro, una excorporazione di alcune funzioni fisiologiche legate all’alimentazione, delegate a strumenti esterni al corpo. Tali azioni sono finalizzate a conformare quest’ultimo ad una “normalità” definita da canoni biomedici, i quali permettono l’inclusione nella collettività “sana”. Il contesto più ampio in cui queste dinamiche si inseriscono, è costituito da una pluralità di discorsi, tra i quali in particolare quelli che riguardano il rapporto tra alimentazione e migrazione. Se da un lato si assiste ad un’ipermobilità delle gastronomie (o dei loro elementi), alla loro delocalizzazione e rilocalizzazione in culture alimentari altre, dall’altro la standardizzazione delle abitudini alimentari proprie alla diversità culturale sembra essere prerogativa essenziale della cosiddetta “integrazione” dei migranti. Tali dinamiche si ripercuotono sulla materialità delle (micro)pratiche quotidiane attorno al corpo che questo intervento si propone di analizzare. Le riflessioni saranno accompagnate da alcuni supporti visivi. [less ▲]

This work is part of a project aiming at developing a renewable fuel for gasification purposes, through the convective drying of sludge/wood mixtures. The first step consists in characterizing the drying behaviour of sludge/sawdust mixtures, in a convective fixed bed dryer. The influence of the mixing step (no mixing against 30 s at 40 rpm) and the sawdust/sludge ratio (1/9, 2/8, 3/7 and 4/6 on a dry basis) was investigated. X-ray tomography, a non-invasive imaging technique, was used to assess changes in volume and exchange surface during drying. The sawdust addition was shown to have a positive impact on the drying process from mass ratio of 2/8. Results showed that the volume and exchange surface increased with higher sawdust addition during the whole drying process. Moreover, a linear decrease of the exchange surface is observed with sludge, while a plateau is reached after a linear phase for sludge/sawdust mixtures. As expected, the drying rate of sludges or sludge/sawdust mixtures decreased nearly linearly with the exchange surface. For sawdust/sludge mixtures, the drying rate continued to decrease after the end of shrinkage, due to internal transfer limitations. These promising results open the way to new valorisation ways, especially for very pasty sludge. [less ▲]

Le Virus de la Varicelle et du zona (VZV) est un herpesvirus humain qui code pour 70 protéines parmi lesquelles 2 protéines kinases: ORF66p et ORF47p. La ser/thr kinase ORF47p, homologue de UL13 d’HSV, est conservée parmi tous les Herpesvirus et fait donc partie des “Conserved Herpesvirus encoded Protein Kinases” (CHPKs). La kinase ORF47p, n’est pas indispensable dans la plupart des cellules, mais elle est essentielle dans les cellules différenciées telles que la peau, les cellules T ou des cellules dendritiques. Elle a été montrée capable de s’autophosphoryler et de phosphoryler des protéines virales, en particulier ORF9p, IE62, IE63, et gE, régulant ainsi les différentes étapes du cycle infectieux. En outre, lors de l’infection par VZV, la protéine IRF3 (Interferon Responding Factor 3), facteur de transcription régulant de la réponse immunitaire innée antivirale apparaît phosphorylée de manière ORF47p-dépendante, empêchant ainsi la mise en place d’une réponse innée efficace. ORF47p apparaît donc comme une kinase capable de moduler à la fois des processus viraux et des processus cellulaires qu’il reste néanmoins à identifier et à caractériser. [less ▲]

The aim of present study was to determine the physicochemical properties of the oil obtained from Tenebrio molitor larvae (mealworms) and explore its potential as edible oil. Five batches of Tenebrio molitor larvae were investigated for their lipid content and physiochemical properties. Three batches were reared in lab (3 different productions) and two were purchased from a local supplier. The lipids were extracted using a cold extraction technique employing 2:1 ratio chloroform/methanol as solvent. The fatty acid profile was determined using gas chromatography and triacylglycerol profile using HPLC. The thermal properties of the lipid extracts were also analyzed using differential scanning calorimetry. All the samples contained high amount of unsaturated fatty acids. The chemical composition and the thermal properties of the samples varied with the source. With this quantity and quality of lipid content, mealworms offer potential as an important source of edible lipids. [less ▲]
