Background: Severe combined immunodeficiency (SCID) can be caused by loss-of-function mutations in genes involved in the DNA recombination machinery, such as RAG1, RAG2 or DCLRE1C. Defective DNA recombination causes a developmental block in T cells and B cells, resulting in high susceptibility to infections. Hypomorphic mutations in the same genes can also give a partial loss of T cells, in a spectrum including leaky SCID (LS) and Omenn syndrome (OS). These patients not only develop life-threatening infections due to immunodeficiency, but also develop inflammatory/autoimmune conditions due to the presence of autoreactive T cells. Objective: We sought to develop a preclinical model that fully recapitulates the symptoms of LS/OS patients including a model for testing therapeutic intervention. Methods: We generated a novel mutant mouse (Dclre1c leaky) that develops a LS phenotype. Mice were monitored for diseases and immune phenotype and immune function were evaluated using flow cytometry, ELISA and histology. Results: Dclre1c leaky mice present with a complete blockade of B cell differentiation, with a leaky block in T cell differentiation resulting in an oligoclonal TCR repertoire and enhanced cytokine secretion. Dclre1c leaky mice also developed inflammatory symptoms including wasting, dermatitis, colitis, hypereosinophilia and high IgE levels. Development of a preclinical murine model for LS allowed the testing of potential treatment, with administration of CTLA4-Ig reducing disease symptoms and immunological disturbance, resulting in increased survival. Conclusion: These data suggest that CTLA4-Ig should be evaluated as a potential treatment of inflammatory symptoms in LS and OS patients. [less ▲]

How can new players seeking to serve nonstandard worker categories (such as project-based workers) establish themselves into labour markets that are highly institutionalized? This paper explores the case of SMart, a Belgian community-based labour market intermediary that successfully developed solutions to better represent the interests of project-based workers and secure their discontinuous careers. Using an organizational legitimacy approach, we find that labour market entry and growth involve different types of boundary-crossing when addressing the needs of workers that do not fit into established categories. However, to justify boundary-crossing, the new player must complement its pragmatic work on delivering new services and tools with conceptual (cognitive) and structural (moral) legitimation work.

This work presents a biased random-key genetic algorithm (BRKGA) to solve the electric distribution network reconfiguration problem (DNR). The DNR is one of the most studied combinatorial optimization problems in power system analysis. Given a set of switches of an electric network that can be opened or closed, the objective is to select the best configuration of the switches to optimize a given network objective while at the same time satisfying a set of operational constraints. The good performance of BRKGAs on many combinatorial optimization problems and the fact that it has never been applied to solve DNR problems are the main motivation for this research. A BRKGA is a variant of random-key genetic algorithms, where one of the parents used for mating is biased to be of higher fitness than the other parent. Solutions are encoded by using random keys, which are represented as vectors of real numbers in the interval (0,1), thus enabling an indirect search of the solution inside a proprietary search space. The genetic operators do not need to be modified to generate only feasible solutions, which is an exclusive task of the decoder of the problem. Tests were performed on standard distribution systems used in DNR studies found in the technical literature and the performance and robustness of the BRKGA were compared with other GA implementations.

Au fil des siècles, le corpus latin des vitae sanctorum et des passiones martyrum s’est enrichi par l’introduction de nouveaux textes, par la réécriture et l’adaptation d’anciens remis au goût du jour, ainsi que par la traduction d’oeuvres issues du monde byzantin. Le phénomène de la réécriture hagiographique est bien connu et a fait l’objet de nombreux travaux. Celui de la traduction dans ce domaine reste en revanche peu exploité, tant il existe d’obstacles à son étude (absence de répertoire, manque d’éditions critiques, difficultés à identifier les traductions et les modèles grecs, etc.). Le présent travail propose une approche originale du phénomène, basée sur l’utilisation de la statistique linguistique. Cette approche consiste à étudier le latin utilisé par les traducteurs hagiographes pour rendre leur modèle grec et les techniques qu’ils ont adoptées pour le traduire en considérant les traductions non pas une à une, mais d’une manière comparative au moyen de l’analyse quantitative, dans le but de caractériser et de classer les traductions sur base de critères linguistiques, d’identifier et de qualifier des pratiques, des traditions localisées, des spécificités d’école ou de traducteur. La pratique de la traduction est examinée à travers un corpus de 35 textes représentatif des différentes phases de l’histoire de la traduction hagiographique latine au Moyen Âge et des différents foyers de traduction en Italie. Les analyses sont menées sur divers paramètres lexicaux et syntaxiques, en comparant d’abord le corpus, pris dans son ensemble, à un corpus de textes non traduits, puis en comparant entre eux les différents sous-corpus de traductions. Le premier type de comparaison (externe) a pour objectif de mettre en évidence les caractéristiques des traductions en général, le second (interne) de dégager les spécificités de chaque groupe de traductions.

Plant rennets hold an important position amongst various coagulants used in cheese technology. The selection of a suitable plant coagulant is important due to the increasing global demands of cheese alongside reduced supply of calf rennet. Thus, a literature synthesis is presented to investigate recent achievements on their functional properties and enzymatic role in cheese making. Efforts have also been done to compare certain rheological and sensory properties of final products, arising from some plant and animal based rennets. In fact, some coagulants such as actinidin or dubiumin produce cheeses with sensory qualities similar to those produced by animal rennet. Others, like ginger, cucumisin or hieronymain proteases contribute to develop very different textures and flavors, due to excessive proteolytic activity and production of bitter peptides. For milk-clotting enzymes with high non-specific action, several improvement strategies have been developed to produce cheeses with sensory properties close to those of animal rennet. For example, the mixture of coagulants (cardosins/chymosin), the selection of appropriate milk or its ultrafiltration, as well as the increase of salting time of cheese during ripening could be efficient ways to improve texture and reduce bitterness. Concerning cheeses with high yield loss, the whey could be used for a traditional production of whey cheese. To conclude, the selection of appropriate plant rennet with high MCA/PA ratio and the optimization of all coagulation parameters play a central role in manufacturing cheese with superior rheological and sensory properties.

The present paper focuses on the development steps of heat exchangers dedicated to single room ventilation unit with heat recovery (SRVHR) by proposing a numerical approach. A methodology is suggested in order to determine the best trade-off between hydraulic and thermal performance given a specific geometry. The methodology consists in a mapping of the coefficient of performance (COP) of the unit. The latter is defined as the ratio between recovered heat and the fan energy use, given a specific indoor/outdoor temperature difference. However, the energy performance should not be the only criterion to be taken into account in the frame of the design steps of a heat recovery exchanger: technical, economic and acoustic aspects should also be considered. This numerical methodology is illustrated by means of a real example of a newly developed heat exchanger dedicated to a SRVHR. The optimization is first performed while using a semi-empirical model (based on the use of correlations and on a spatial division of the studied heat exchanger). The semi-empirical model allows for the creation of a COP map in order to identify the most effective geometry parameters for the heat exchanger. The decision concerning the final geometry is made accounting for the so-called technical, economic and acoustic considerations. A discussion on some parameters needed for the COP establishment is also proposed. [less ▲]

Climate change is widely accepted to be one of the most critical problems faced by the Huang-Huai-Hai Plain (3H Plain), which is a region in which there is an over-exploitation of groundwater region and where future warmer and drought conditions might intensify crop water demand. In this study, the spatiotemporal patterns of ET0 and primary driving meteorological variables were investigated based on a historical and RCP 8.5 scenario daily data set from 40 weather stations over the 3H Plain using linear regression, spline interpolation method, a partial derivative analysis and multivariate regression. The results indicated a negative trend in all the analysis periods (except spring) of the past 54 years of which only summer and the entire year were statistically significant (p < 0.01) with slopes of -1.09 and -1.30 mm·a-1 respectively. In contrast, a positive trend was observed in all four seasons and the entire year under the RCP 8.5 scenario, with the biggest increment equal to 1.36 mm·a-1 in summer and an annual increment of 3.37 mm·a-1. The spatial patterns of the seasonal and annual ET0 exhibited the lowest values in southeastern regions and the highest values in northeastern parts of Shandong Province, probably because of the combined effects of various meteorological variables over the past 54 years. Relative humidity (RH) together with solar radiation (RS) were detected to be the main climatic factors controlling the reduction of ET0 in summer, autumn, and the entire year on the 3H Plain. ET0 in spring was mainly sensitive to changes in RS and RH, whereas ET0 in winter was most sensitive to changes in wind speed (WS) and decreased due to declining RH. Under the future RCP 8.5 scenario, the annual ET0 distribution displays a rich spatial structure with a clear northeast-west gradient and anarea with low values in the southern regions, which is similarly detected in spring and summer. The most sensitive and primary controlling variables with respect to the increment of future ET0 are in the first place RS and then mean temperature in spring, while turn to be mean temperature and then RS in summer. In autumn, future ET0 is most sensitive to RH changes. WS and RH are the controlling variables for ET0 in winter. Annual future ET0 is most sensitive to RH changes and accordingly RS is responsible for the predicted increment of the annual ET0. Better understanding of current and future spatiotemporal patterns of ET0 and of the regional response of ET0 to climate change can contribute to the establishment of a policy to realize a more efficient use of water resources and a sustainable agricultural production in the 3H Plain.

Northern Morocco has an important local ceramic industry. Twenty-three Craterous and Pliocene clays from Tangier area (Northern Morocco) were studied to test their suitability as raw material for fired brick production. To assess their behaviour, the chemical composition, specific surface area (SSA), cation exchange capacity (CEC), and apparent density of clays were determined. The chemical composition consisted mainly of SiO2 (32 – 60%), Al2O3 (7 – 30%), and CaO (0.5 – 32%). SSA and CEC values of all the samples were low. The apparent density, pore volume, and micropore values were almost similar. Clay bricks were prepared by forming and shaping, and then fired in the range of 800 – 1100°C. Firing shrinkage, loss on mass and water absorption capacity were done in order to characterize clays after firing. Most of the clay samples have the necessary properties for the manufacturing of brick products. However, some clay samples were above the norm of loss on weight, due mainly to their high amount of carbonates. Furthermore, some kaolinitic samples from Pliocene blue marls and Cretaceous marls are inappropriate for building-related brick fabrication, because of the development of portlandite in brick, when in contact with moisture of the air. However, it will be necessary to mix them with other clays with little or no carbonate to dilute their carbonates content and then enhance their workability. [less ▲]

This paper offers a reconstruction of Külpe’s theory of cognitive attitudes from the perspective of contemporary debates about cognitive phenomenology. I argue that Külpe’s view constrasts with analytic mainstream approaches to the same phenomena in at least two respects. First, Külpe claims, cognitive experiences are best described in terms of occurrent cognitive acts or attitudes toward sensory, imagistic or intellectual contents. Second, occurrent cognitive attitudes are intransitively conscious in the sense that they are experienced by, or phenomenally manifest to, the subject. I call the combination of those two claims the conscious cognitive attitudes theory. I suggest that, despite some difficulties, this theory offers a worth-considering alternative to contentual and/or nonphenomenological theories of cognitive phenomena. [less ▲]

The whitemouth croaker, Micropogonias furnieri, is a long-lived fish of high commercial importance in the Western Atlantic Ocean. Here, we used stable isotope ratios of carbon, sulfur and nitrogen and isotopic niche metrics (SIBER) to study feeding habits and track habitat use by whitemouth croakers in Guanabara Bay, an estuary in Rio de Janeiro state, Brazil. Our results highlighted size-related habitat segregation, with small juvenile (< 30 cm) fishes residing mostly inside estuaries, while large adult (> 60 cm) fishes feed mainly in Continental Shelf (CS) waters. Medium adult fishes (30-60 cm) appear to feed in multiple coastal and CS habitats. Moreover, their feeding ecology showed strong temporal differences, linked with seasonal and, to a lesser extent, inter-annual variation in oceanographic features of the ecosystem in which they live. Overall, these differences in ecological features suggest that (1) adult and juvenile whitemouth croakers should be treated as different components of the food web and (2) the conservation of these habitats should be prioritized to better manage and sustain the coastal fisheries in Guanabara Bay.

In section 2 I present Brentano’s mereological solution and in section 3 I review his main pro-arguments. Eventually, in section 4 I consider some Jamesian objections to the mereological approach. I argue the notion of ‘mental parts’ can be given a rather innocuous meaning by being conceived of as the expression of conceptual distinctions grounded in similarity and contrast relations between total mental phenomena.

Elderspeak is often used when talking to older individuals and is characterized by a slower and/or louder speech, a patronizing tone, etc. A part of the reason of such communication can be found in the actual context of negative view of aging. However, the link between view of aging and elderspeak has never been objectively studied in oncology. Therefore, 40 healthcare professionals (physicians and medical students) record a podcast where they have to explain an endocrine therapy to two fictional patients (40 vs 70 years old). Results show that when participants explained the treatment to the older patient, they used shorter utterances and made more repetitions. They also evoked fewer side effects such as sexual issues. Moreover, reduction of length of utterances and of word-per-minute rate was observed for older patient when participants have a positive view of aging but for both patients when they have a negative view of aging. In conclusion, physicians and medical students used elderspeak when they explained a treatment to older patients. Participants with a more negative view of aging also unconsciously talked slower and made shorter utterances to a 40 year-old patient. [less ▲]

Introduction: Given that recent research has shown that functional connectivity is not a static phenomenon, we aim to investigate the dynamic properties of the default mode network’s (DMN) connectivity in patients with disorders of consciousness. Methods: Resting-state fMRI volumes of a convenience sample of 17 patients in unresponsive wakefulness syndrome (UWS) and controls were reduced to a spatiotemporal point process by selecting critical time points in the posterior cingulate cortex (PCC). Spatial clustering was performed on the extracted PCC time frames to obtain 8 different co-activation patterns (CAPs). We investigated spatial connectivity patterns positively and negatively correlated with PCC using both CAPs and standard stationary method. We calculated CAPs occurrences and the total number of frames. Results: Compared to controls, patients showed (i) decreased within-network positive correlations and between-network negative correlations, (ii) emergence of “pathological” within-network negative correlations and between-network positive correlations (better defined with CAPs), and (iii) “pathological” increases in within-network positive correlations and between-network negative correlations (only detectable using CAPs). Patients showed decreased occurrence of DMN-like CAPs (1–2) compared to controls. No between-group differences were observed in the total number of frames Conclusion: CAPs reveal at a more fine-grained level the multifaceted spatial connectivity reconfiguration following the DMN disruption in UWS patients, which is more complex than previously thought and suggests alternative anatomical substrates for consciousness. BOLD fluctuations do not seem to differ between patients and controls, suggesting that BOLD response represents an intrinsic feature of the signal, and therefore that spatial configuration is more important for consciousness than BOLD activation itself.

Despite the common conception of the dorsal premotor cortex (PMd) as a single brain region, its diverse connectivity profiles and behavioral heterogeneity argue for a differentiated organization of the PMd. A previous study revealed that the right PMd is characterized by a rostro-caudal and a ventro-dorsal distinction dividing it into five subregions: rostral, central, caudal, ventral and dorsal. The present study assessed whether a similar organization is present in the left hemisphere, by capitalizing on a multimodal data-driven approach combining connectivity-based parcellation (CBP) based on meta-analytic modeling, resting- state functional connectivity, and probabilistic diffusion tractography. The resulting PMd modules were then characterized based on multimodal functional connectivity and a quantitative analysis of associated behavioral functions. Analyzing the clusters consistent across all modalities revealed an organization of the left PMd that mirrored its right counterpart to a large degree. Again, caudal, central and rostral modules reflected a cognitive- motor gradient and a premotor eye-field was found in the ventral part of the left PMd. In addition, a distinct module linked to abstract cognitive functions was observed in the rostro- ventral left PMd across all CBP modalities, implying greater differentiation of higher cognitive functions for the left than the right PMd.

While it goes undisputed that international criminal tribunals (ICTs) are, in general terms, bound to respect human rights standards, there is no consensus on whether their obligations should be identical in scope to those of national criminal tribunals. Most commentators seem to value the idea of equality in protection for international and domestic defendants alike. Yet, according to others, the human rights obligations of ICTs should be contextualised, that is, adapted to the specificities of international justice – and most critically to the gravity of international crimes. This article seeks to shed some light on this debate. It does so, in particular, by pointing out the intrinsic flexibility of human rights, and by drawing on the practice of the European Court of Human Rights with respect to gravity-based contextualism.

Even if insect pest populations can be reduced by increasing plant diversity through intercropping, natural enemies are not always favored in such systems. Alternatively, semiochemical substances have been tested to enhance biological control, with inconsistent results. Combining both strategies can be an interesting way to maximize pest control. In this work, a 2-year setup involving wheat–pea strip intercropping combined with the release of E-b-farnesene (EBF) or methyl salicylate (MeSA) was tested as a push–pull strategy to simultaneously repel aphids and attract beneficials. Two types of slow-release formulation (i.e., oil and alginate beads) containing EBF or MeSA were deployed with the intercropping. The abundance of aphids was significantly decreased, while hoverfly larvae and mummified aphids increased on both pea plants and wheat tillers by the release of oil-formulated EBF and MeSA. The proportion parasitism of the aphid-parasitism rate [mummies/(aphids + mummies)] was also increased by treating both crops in both years. Releasing EBF through oil rather than alginate beads proved significantly better for attracting natural enemies and reducing aphids. Aphids were negatively correlated with the density of hoverflies (both adults and larvae) and numbers of mummies. All these results showed that combining intercropping with the release of EBF or MeSA formulated in oil can significantly reduce aphid density and attract their natural enemies. Therefore, the combination of both strategies could help farmers reduce the use of insecticides. [less ▲]

A coupled Electro-Thermo-Mechanical Discontinuous Galerkin (DG) method is developed considering the non-linear interactions of electrical, thermal, and mechanical fields. In order to develop a stable discontinuous Galerkin formulation the governing equations are expressed in terms of energetically conjugated fields gradients and fluxes. Moreover, the DG method is formulated in finite deformations and finite fields variations. The multi-physics DG formulation is shown to satisfy the consistency condition, and the uniqueness and optimal convergence rate properties are derived under the assumption of small deformation. First the numerical properties are verified on a simple numerical example, and then the framework is applied to simulate the response of smart composite materials in which the shape memory effect of the matrix is triggered by the Joule effect.

We study retirement incentives with an augmented reduced form option value model à la Stock and Wise (1990). We propose methodological extensions to better reflect the respective incentives faced by singles and couples. Our results show that a more comprehensive modelling of couples’ incentives leads to very different patterns of retirement incentives – particularly for women. We apply the new indicators to data from the Survey of Health, Ageing and retirement in Europe (SHARE) in Belgium and find two key results. First, contrary to several previous studies, we obtain a positive signed income effects. Second, we find very different retirement incentives for men and women, with little flexibility in the retirement decision for men and substantially more flexibility for women as a function of financial incentive and household composition.

Shallow reservoirs are often used as sediment traps or storage basins, in which sedimentation depends on the flow pattern: Short rectangular reservoirs reveal a straight jet from inlet to outlet with on both sides identical recirculation zones. In longer reservoirs, the main jet reattaches to the side of the reservoir leading to a small and a large recirculation zone. Previous studies found an empirical geometric relation describing the switch between these two flow patterns. In this study, we demonstrate, with a simple analytical model, that this switch coincides with a maximization of energy dissipation in the shear layer between the main jet and recirculation zones: Short reservoirs dissipate more energy when the flow pattern is symmetric, while longer reservoirs dissipate more energy with an asymmetric pattern. This approach enables to predict the flow patterns without detailed knowledge of small scale processes, potentially useful in the early phase of reservoir design. [less ▲]

INTRODUCTION: Vitamin D insufficiency, defined by a 25-hydroxyvitamin D (25OHD) serum concentration<20ng/mL, is highly frequent in the French general population, especially between November and April. The aim of this study was to evaluate whether 80,000 IU vitamin D3 every month during this period of the year was able to maintain a 25OHD level between 20 and 60ng/mL in apparently healthy subjects whatever their basal vitamin D status. METHODS: Ninety-eight subjects volunteered to receive an 80,000 IU vitamin D3 dose every month between November 2014 and April 2015. Serum 25OHD, calcemia and calciuria were measured just before the first dose (Month 0), just before the 4th dose (M4), and one month after the 6th dose (M7). RESULTS: At M0, 25OHD was 17.5+/-9.5ng/mL. Sixty subjects (61.2%) had a 25OHD<20ng/mL and 25 (25.5%) had a 25OHD<10ng/mL. 25OHD increased significantly at M4 (35.3+/-8.0ng/mL) and M7 (40.1+/-8.5) without change in calcemia and calciuria. At M4, 2 subjects had a 25OHD slightly below 20ng/mL (17.6 and 19.7ng/mL), and none had a concentration>60ng/mL. At M7, all had a serum 25OHD>20ng/mL and 2 subjects had a value slightly above 60ng/mL (62.1 and 63.2ng/mL). CONCLUSION: A monthly supplementation with 80,000 IU vitamin D3 between November and April corrected vitamin D insufficiency in subjects in whom it was initially very frequent, without overdosing. This protocol is simple, safe and costless, and can be easily implemented when physicians detect risk factors for hypovitaminosis D in patients for whom a 25OHD measurement is not indicated.

Surface-enhanced Raman spectroscopy (SERS) is a sensitive analytical tool used in the pharmaceutical field in recent years. SERS keeps all the advantages of classical Raman spectroscopy while being is more sensitive allowing its use for the detection and the quantification of low-dose substances contained in pharmaceutical samples. However, the analytical performance of SERS is limited due to the difficulty to implement a quantitative methodology correctly validated. Nevertheless, some studies reported the development of SERS quantitative methods especially in pharmaceutical approaches. In this context, this review presents the main concepts of the SERS technique. The different steps that need to be applied to develop a SERS quantitative method are also deeply described. The last part of the present manuscript gives a critical overview of the different SERS pharmaceutical applications that were developed for a non-exhaustive list of pharmaceutical compounds with the aim to highlights the validation criteria for each application.

One of the main consequences of the Roman conquest was the diffusion of the Latin language and of Roman culture throughout the conquered countries. According to many texts of the imperial period, Latin became a universal language during the Imperium Romanum. But what is the reality? Did Rome develop any linguistic policies? There is some evidence to show that Rome’s response regarding the sociolinguistic problems that arose under its rule was to be flexible and willing to adapt to the specific requirements of each situation. Under the Republic and the early Principate, there was, in fact, a great flexibility in language use by the Romans in their dealings with the Greek world. Even though Latin-Greek bilingualism was widespread among the Romans of the Republic and the early Principate, in the public context, Latin maintained a high-level role because it represented the language of Rome’s power. In spite of this flexible approach to language use, a natural competition developed between the language of the dominant and the language of the dominated. In the Occident, Latin became the only vehicle of communication, both oral and written, whereas in the Orient, one notes a paradoxical situation: the Hellenization of the Romans due to the high cultural position of the Greek language. However, this dichotomy did not produce a division of the Roman Empire into two impenetrable parts, closed to mutual linguistic and cultural influences, but rather, it generated a more complicated situation, especially in the Oriental part of the Empire. It is this situation that will be analyzed in the present paper. [less ▲]

District heating networks (DHN) are generally considered as a convenient, economic and environmental-friendly way to supply heat to a large amount of buildings. Some modelling methods are required to consider the dynamic behaviour of district heating networks to design them correctly, spare the investment costs and limit the heat losses related to the use of a too high operating temperatures. For the same reasons, the DHN control or retrofit of installations also requires the assessment of the DHN dynamic behaviour. To achieve this, the heat transport in DHN, which is one of the key issues in the behaviour of a whole centralized heating system, has to be correctly modelled. Previous work evidenced current limitations of one dimensional finite volume method to model heat transport in pipes and proposed an alternative method considering the thermal losses and the inertia of the pipes. The present contribution intends to experimentally validate this model on a test rig available at the Thermodynamics laboratory of the University of Liège (ULg, Belgium) and on an existing district heating network. For both experimental facilities, the current model shows good agreement between the experimental data and the simulation results for a large range of water velocities. Moreover, it is shown that the thermal inertia of the pipe has a significant influence on the outlet pipe temperature profile. [less ▲]

Common clay deposits from five localities in Foumban (West Cameroon) were investigated for their morphological, mineralogical and geochemical properties to determine their potential source rocks and suitability in ceramic product. The analytical results were obtained by X-ray diffraction, X-ray fluorescence spectrometry, Thermogravimetric Analysis, Scanning Electron Microscopy, and Fourier Transform Infrared Spectrometry. Morphologically, an homogeneous clayey layer was found in the upper part of a laterite cover on interfluves, and a clayey heterogeneous hydromorphic material in valleys. They are minerallogically composed of kaolinite (25-84%), illite (0-18%), smectite (0- 31%), and chlorite (0-8 %), associated with quartz (2-44 %), K-feldspars (0-27 %.), plagioclase (0-26%), goethite; (0-9%) with traces of rutile and hematite (≤5 %). The geochemical analysis shows a 115 relative large amount of SiO2 (45-71%), Al2O3 (14-31%), and low Fe2O3 (up to 11 %) suggesting weathering of mainly granitic and rhyolitic parent rocks. Most studied clays could be applied to building ceramic product such as bricks (refractory or not) and tiles. Illite may promote the glassy phase responsible for the densification of the final product. In addition, the relatively high proportion of alkali elements (K2O + Na2O, 6-8%) in some samples from Marom, Koutaba and is responsible for low firing temperature. However the presence of smectite (up to 5 %) limits the application of some Koutaba and Marom clays for ceramic building. The high Fe2O3 contents (> 8 %) in some Bangourain clays implied some pretreatment. [less ▲]

Understanding how the productivity of water can be increased is widely accepted to be a high priority where water resources are currently scarce and/or over-exploited in China. As the primary data source, MODIS remote sensing, statistics, meteorological data, crop growth period data and ground truth-data from Jan. 2011 to Dec. 2012 were used in actual evapotranspiration estimation, yields rasterizing, and water productivity calculation for winter wheat in the Huang-Huai-Hai Plain (3H Plain). The statistical data were synthesized to calculate district-state-level land productivity, which is then further extrapolated to pixel-level values using a MODIS NDVI image, based on a crop dominance map. Spatial variation of crop water productivity was investigated in order to reveal the key factors of crop water productivity. In addition, the relationship between water productivity and actual evapotranspiration and in subsequence yield for winter wheat was discussed in 3H Plain. The main results indicated that the SEBAL is suitable for estimating evapotranspiration in winter wheat based on the comparation between evapotranspiration measured by Yucheng (in Shandong province). The regional average value of water productivity for winter wheat was detected to be 1.21kg·m-3, with the higher value in Beijing, Tianjin, north part of Shandong province and south part of Hebei province. The pronounced relationship of spatial correlation of the yield and water productivity for winter wheat indicated that the increasing yield governed the increment of water productivity for winter wheat in the coastal land-farming-fishing area (zone1), low plain-hydropenia irrigable land and dry land zone (zone2) and basin- irrigable land and dry land (zone5). The increasing water productivity for winter wheat was recognized to be controlled by rather the increment of yield than the reduction of actual evapotranspiration for winter wheat in the piedmont plain-irrigable land (zone2). Whereas, the pronounced relationship of negative correlation of water productivity and actual evapotranspiration for winter wheat described that only the reduction of actual evapotranspiration was responsible for the increment of water productivity for winter wheat in hill-wet hot paddy-paddy field (zone6). The results is expected to provide a basis information for agricultural water management, improvement of crop water productivity and choice of adaptive mechanism under climate change in Huang-Huai-Hai plain.

Episodic memories are typically composed of perceptual information derived from the external environment and representations of internal states (e.g., one’s thoughts during prior episodes). To date, however, research has mostly focused on the remembrance of external stimuli, such that little is known about how internal mentation is represented within episodic memory. In the present fMRI study, we examined the neural correlates of these two components of episodic memories using a novel method of cuing memories from photographs taken during real-life events. We found that, compared to corresponding semantic memory tasks, memories for internal thoughts and external elements were associated with activity in brain areas supporting episodic recollection. Most importantly, however, the two kinds of memories also showed differential activation in large-scale brain networks: the remembrance of external elements was associated with greater activity in the dorsal attention network, whereas memories of internal thoughts mainly recruited default network areas. These findings shed new light on the representation of internal and external aspects of prior experience within episodic memory. The default network may contribute to the reinstatement of thoughts experienced during past events, whereas the dorsal attention network may support the allocation of attention to visuo-spatial features within episodic memory representations.

This paper proposes a novel tracking state estimator to process both fast-rate synchronized phasor and slow rate SCADA measurements. The former are assumed to be in limited number. The latter are exploited as and when they arrive to the control center. In order to restore observability, after each execution of the tracking state estimator, forecasted SCADA measurements are used as pseudo-measurements in the next estimation. An event detection analysis allows assessing if the system is in quasi steady-state. If so, an innovation analysis is performed to identify and eliminate erroneous SCADA measurements. The system state is computed by Hachtel’s augmented matrix method. The option of exploiting time-tagged SCADA measurements is also considered. The method is illustrated through detailed dynamic simulations of a test system evolving towards voltage collapse, with and without emergency control. [less ▲]

Going back to the origins of the ‘case mémorable’ in the pages of Les Cahiers de la bande dessinée, this article revisits the debates between Pierre Sterckx and Benoît Peeters, articulated around a conceptual tension between linear and tabular, about the relationship between single panels and narrative. It proposes that the ‘remembered panel’ pinpoints important issues about the recirculation of single images, isolated from their contexts, and the discourse of memory that becomes associated with it. A close-reading of Olivier Josso Hamel’s Au travail, in which the cartoonist redraws his own set of remembered panels, further calls for a reconsideration of Sterckx’s concept in the light of a creative practice that intimately engages with the memory of such panels in a complex relationship to their original narratives.

BACKGROUND: Different clinical trials show beneficial effects of physical training offered during and / or after breast cancer treatment. However, given the variety of side effects that may be encountered, physical training could be combined with psychological, relational and social guidance. This kind of multidisciplinary program has been little studied so far. AIM: To determine the benefits of a three-month multidisciplinary rehabilitation program among women after breast cancer treatment. DESIGN: Controlled no-randomized trial. SETTING: University for outcomes, University Hospital Center for interventions. POPULATION: Two hundred and nine outpatients who have been treated for a primary breast carcinoma. METHODS: Patients were divided into a control group (n=106) and an experimental group (n=103) which has benefited from a rehabilitation program of three months including physical training and psycho-educational sessions. The assessments, performed before and after the program, included functional assessments ("Sit and Reach Test", maximal incremental exercise test and "Six-Minute Walk Test"), body composition measurements (body mass index (BMI) and body fat percentage) and a questionnaire (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire-Core 30). RESULTS: After three months, flexibility, walking distance and all parameters measured during the maximal incremental exercise, except maximal heart rate, were significantly improved in the experimental group. The body fat percentage was significantly decreased and a significant improvement was observed for perceived health status (quality of life), functional role, emotional state, physical, cognitive and social functions and for most symptoms. In the control group, most of these improvements didn't appear and a significant increase in BMI and body fat percentage was observed. CONCLUSIONS: This trial identifies the benefits of a well detailed multidisciplinary rehabilitation program, including physical re-conditioning and psycho-educational sessions, with important improvements in functional capacity, body composition and the majority of functions and symptoms among women after breast cancer treatment. CLINICAL REHABILITATION IMPACT: Through its results, this study could contribute to the development of hospital quality standards for oncologic rehabilitation. Physiotherapists can efficiently propose this kind of multidisciplinary rehabilitation program. [less ▲]

Poly(hydroxyurethane) (PHU) thermosets reinforced with (functional) nanofillers were developed to design high performance adhesives for bare aluminum. Solvent-free cyclic carbonate/amine/PDMS formulations loaded with native, epoxy- or cyclic carbonate-functionalized ZnO nanofillers were premixed before deposition and thermal curing onto Al. The results highlight that the addition of PDMS prevents PHUs from delamination of the Al surface by increasing the adhesive hydrophobicity and thus limiting the water uptake. The dispersion of functional fillers within PHUs improves their thermal and mechanical properties. Benchmarking of the adhesive performances of the reinforced PHU glues with existing PHU formulations attests for the benefits of dispersing functional fillers and PDMS within the resin and evidences a 270% increase of the shear strength of reinforced PHUs adhesives compared to formulations reported in the literature.

Background: Identifying older people affected by cancer who are more at risk of negative health outcomes is a major issue in health initiatives focusing on medical effectiveness. In this regard, psychological risk factors such as patients’ perception of their own aging and cancer could be used as indicators to improve customization of cancer care. We hypothesize that more negative self-perception of aging (SPA) and view of cancer could be linked to worse physical and mental health outcomes in cancer patients. Methods: 101 patients diagnosed with cancer (breast, gynecological, lung or hematological) were followed for one year. They were evaluated on four occasions (baseline, 3, 6 and 12 months after the baseline). Their SPA, view of cancer and health (physical and mental) were assessed at each time of evaluation. Results: Negative SPA and/or view of cancer at baseline are associated with negative evolution of patients’ physical and mental health. Moreover, when the evolution of SPA and cancer view were taken into account, these two stigmas are still linked with the evolution of mental health. In comparison, only a negative evolution of SPA was linked to worse physical health outcomes. Conclusions: Such results indicate that SPA and view of cancer could be used as markers of vulnerability in older people with cancer. [less ▲]

Modelling the entire ductile fracture process remains a challenge. On the one hand, continuous damage models succeed in capturing the initial diffuse damage stage but are not able to represent discontinuities or cracks. On the other hand, discontinuous methods, as the cohesive zones, which model the crack propagation behaviour, are suited to represent the localised damaging process. However, they are unable to represent diffuse damage. Moreover, most of the cohesive models do not capture triaxiality effect. In this paper, the advantages of the two approaches are combined in a single damage to crack transition framework. In a small deformation setting, a non-local elastic damage model is associated with a cohesive model in a discontinuous Galerkin finite element framework. A cohesive band model is used to naturally introduce a triaxiality-dependent behaviour inside the cohesive law. Practically, a numerical thickness is introduced to recover a 3D-state, mandatory to incorporate the in-plane stretch effects. This thickness is evaluated to ensure the energy consistency of the method and is not a new numerical parameter. The traction-separation law is then built from the underlying damage model. [less ▲]

In order to investigate the relationship between desiccation and the extent of protein oxidation in desert strains of Chroococcidiopsis a selection of 10 isolates from hot and cold deserts and the terrestrial cyanobacterium Chroococcidiopsis thermalis sp.

PCC 6803 were further investigated for protein oxidation after desiccation (drying over silica gel), treatment with H2O2 up to 1M and exposure to γ-rays up to 25 kGy. Then a selection of desert strains of Chroococcidiopsis with different survival rates after prolonged desiccation, as well as Synechocystis sp. PCC 6803 and Chroococcidiopsis thermalis sp.

This work aimed to study the chemical composition of essential oils and floral waters of Cymbopogon citratus (DC.) Stapf (Poaceae) from Senegal. The plants were collected in two different localities, Dakar and Kaolack. The extracts were obtained by steam distillation from both fresh and dried plants and analyses carried out by GC/FID and GC/MS. Oils from Dakar were dominated by geranial which represented 46.0-43.9%, neral 31.8-31.0%, myrcene 10.8-11.7% and geraniol 2.7-4.2% in the fresh and dried plants, respectively. Their floral waters contained mainly 44.6-41.4% geranial, 39.7-35.6% neral and 8.8-13.2% geraniol. The oils from Kaolack were characterized by geranial which constituted 49.5-44.5%, neral 33.3-31.2%, myrcene 7.2-9.6% and geraniol 4.3-6.1% in the fresh and dried plants, respectively. In their floral waters, it is identified 42.8-33.6% geranial, 38.4-27.6% neral and 12.5-24.5% geraniol. This original study revealed that both oils and floral waters of C. citratus from Senegal are characterized by geranial and neral whose repellent properties against mosquitoes are known. [less ▲]

Shallow reservoirs are used for multiple purposes, such as storm water retention and trapping of sediments. Reliable predictions of the flow fields are necessary to inform the design and operation of these structures. Using numerical simulations, we performed a systematic analysis of the influence of the location of the inlet and outlet on the flow fields developing in rectangular shallow reservoirs of various sizes. Depending on the relative location of the inlet and outlet with respect to the reservoir centreline, contrasting flow patterns are obtained, involving either no flow reattachment, or a jet reattached on either of the reservoir sidewalls. The results reveal also the occurrence of bi-stable flow configurations, i.e. different steady state flow fields are reached depending on the flow history. This is of high relevance for the design of shallow reservoirs as such configurations should certainly be avoided to achieve a robust hydraulic sizing of the reservoir. [less ▲]

Hybrid organizational forms combine values and practices from different institutional domains, rendering them difficult to fit neatly into the structures of extant organizational forms. Since the work required to institutionalize a new hybrid organizational form may be beyond the resources and capabilities of individual organizations acting alone, we shift the focus to inter-organizational collective action. Using empirical data from a study of a European network of renewable energy cooperatives, we find that, in order to institutionalize the new hybrid organizational form, the network can contribute to overcome the legitimacy challenges inherent in organizational hybridity. In particular, the network builds field-level receptivity to institutional pluralism, collectively codifies the hybrid organizational form, and consolidates legitimation towards plural field-level audiences. In order to perform these institutionalization roles, the network itself becomes increasingly formalized and mobilizes mediating functions involving different types of resources, legitimacy and target audiences. The research advances knowledge of hybrid organizational forms and their collective institutionalization through inter-organizational networks. [less ▲]

Flowers are susceptible to many pests and diseases. Therefore, they can be sprayed several times during their growth considering that no MRL are set for flow-ers. High levels of pesticide residues potentially expose daily the florists who han-dle cut flowers and possibly could endanger their health. A study was carried out to evaluate the risk for florists exposed to fungicide residues during normal profes-sional tasks. Cotton gloves were distributed to 20 florists (two pairs to each florist) and worn during two consecutive half days during normal professional tasks (from min 2 hours to max 3 hours/day) to measure their potential dermal exposure (PDE). Samples were analyzed with a multi-residue (QuEChERS) method validated by a laboratory accredited for pesticide residues and with a combination of gas and liquid chromatography tandem mass spectrometry. It appears from the results that a total of 54 fungicides with different toxicity classes were detected on cotton gloves. An average of 15.53 mg/kg fungicide residues per glove sample was meas-ured. Six of 54 are suspected of causing cancer after prolonged or repeated expo-sure. Boscalid was both the active substance for which the highest maximum and average concentrations (26.21 and 3.47 mg/kg, respectively). Famoxadone had the most critical PDE (156% AOEL for the maximum concentration). As a consequence, this study leads to conclude that Belgian florists, who worked for several years and handled a large number of flowers contaminated by high concentrations of pesti-cide residues, are exposed daily with a potential effect on their health. This sug-gests that safety standards should be set for residue levels on cut flowers. [less ▲]

Estrogens derived from brain testosterone aromatization (neuro-estrogens) are critical for the activation of male sexual behavior. Their effects on this behavior are typically associated with long-term changes in circulating levels of testosterone and the transcriptional activity of their liganded nuclear receptors. According to this view, neuro-estrogens would prime the neural circuits controlling the long-term expression of behavior, which would then be acutely regulated by neurotransmitter systems conveying information from the social environment. In parallel, neuro-estrogens are also able to produce much faster effects than previously anticipated. Our recent investigations in Japanese quail revealed an interesting dichotomy in the regulation of male sexual behavior by membrane- and nuclear-initiated estrogen signaling providing respectively an acute modulation of sexual motivation and a long-term control of the capacity to display the copulatory sequence. In parallel, a similar dichotomy applies to the regulation of brain aromatase whose expression depends on the transcriptional activity of testosterone metabolites while its enzymatic activity is rapidly regulated in a region- and context-dependent manner. Recent evidences suggest that rapid changes in sexual motivation result from rapid changes in local estrogen production. Together, these data support the idea that the acute regulation of some aspects of male sexual behavior depends not only on classical neurotransmitter systems, but also on rapid and spatially restricted changes in local estrogen availability. The existing literature suggests that this acute regulation by neuro-estrogens of the motivational aspects of behavior could be generalized to other systems such as singing behavior in songbirds.

The Typus Melancholicus (TM) is a pre-melancholic personality structure, defined by Tellenbach and Kraus and characterized by the orderliness, conscientiousness, norm orientation and intolerance of ambiguity. This study aims to discriminate the existence of a subgroup TM, among a unipolar depressive population. In order to prove the existence of this subgroup, we translated and administrated the Criteria for Typus Melancholicus (CTM) to a sample of 20 unipolar patients and 20 control participants. The research hypothesis was to find a similar proportion to the one observed in the literature (50% of TM in the unipolar sample). The results demonstrate, as expected, that half of the unipolar sample belongs to a homogeneous subgroup that displays the TM features. Furthermore, no control subjects displays the TM features. Those results suggest that the TM features design a coherent and typical psychopathological structure that can be found in an important proportion of unipolar depressive population. Our study identifies and confirms the existence of a distinct heterogeneity (TM/noTM) inside the unipolar group. This distinction opens the door to some important perspectives in terms of therapy.

In half the cases, bipolar disorder begins before adulthood. The usual long delay between its onset and the establishment of proper treatment has adverse effects on the developing brain. The prognosis of the disease could be improved by early diagnosis and treatment. From the case of a manic episode in a 16 year old teenager, we discuss the characteristics of manic prodromes, their diagnostic criteria and therapeutic means. We then criticize the concept of diagnosis in the stage of prodromal symptoms. We propose to dispense with the need for diagnosis and promote access to mental health care to any person with mental suffering. [less ▲]

This paper aims at validating pressure and velocity measurements conducted in two physical scale models of an ogee spillway crest operating at heads largely greater than the design head. The design head of the second model is 50% smaller than the one of the first model. No pier effect or air venting is considered in the study. The velocity field is measured by Bubbles Image Velocimetry. The relative pressure along the spillway crest is measured using pressure sensors. Comparison of measured velocities between both spillways indicates low scale effects, the scaled-profiles collapsing in most parts of the flow. By contrast, measurements of relative pressure along the spillway crest differ for large heads. A theoretical velocity profile based on potential flow theory and expressed in a curvilinear reference frame is fitted to the velocity measurements, considered as reference, for extrapolating the velocity at the spillway crest. Comparing the extrapolated velocity at the spillway crest and the velocity calculated from the relative pressure considering a potential flow finally emphasizes that bottom pressure amplitudes seem overestimated for the larger spillway, while an averaging effect might operate for the pressure measurements on the smaller spillway.

Well-defined poly(lactide)-based block copolymers were synthesized by a heterogeneous solvent and metal-free green approach by using organocatalysts in supercritical carbon dioxide (scCO2). We first report on the homopolymerization of both L- and D,L- lactide by organocatalyzed Ring-Opening Polymerization (o-ROP) by using a bicomponent organocatalyst composed of a thiourea derivative and various tertiary amines as cocatalysts. Control over the molar mass and dispersity is achieved until high monomer conversion although the polylactides are insoluble in the polymerization medium. The precision synthesis of PLA-based block copolymers from various CO2-phobic hydroxyl end-capped macroinitiators such as polyethylene glycol, polycaprolactone, polybutylene succinate and polyphosphoester was then reported. Merging scCO2 with this organocatalytic system provides therefore a unique tool for the design under solvent-free conditions of poly(lactide)-based block copolymers that are insoluble in scCO2.

This paper reviews the state-of-the-art methods to perform structural optimization of flexible mechanisms. These methods are based on a system-based approach, i.e. the formulation of the design problem incorporates the time response of the mechanism that is obtained from a dynamic simulation of the flexible multibody system. The system-based approach aims at considering as precisely as possible the effects of nonlinear dynamic loading under various operating conditions. Also, the optimization process enhances most existing studies which are limited to (quasi-) static or frequency domain loading conditions. This paper briefly introduces flexible multibody system dynamics and structural optimization techniques. Afterwards, the two main methods, named the weakly and the fully coupled methods, that couple both disciplines are presented in details and the influence of the multibody system formalism is analyzed. The advantages and drawbacks of both methods are discussed and future possible research areas are mentioned. [less ▲]
