The iatromagical papyri, subgenus of the magical papyri, come from Egypt. From the 1st BC to AD the 7th, they appear in the form of formularies, spells copied from them, amulets and a private letter. For many years, the study of these texts has been part of a research program of the Centre de Documentation de Papyrologie Littéraire (CeDoPaL) of the University of Liège. We will present here the results from the analysis of the content of the prescriptions with plants attested in the Greek iatromagical formularies. [less ▲]

Agricultural management practices influence soil structure, but the characterization of these modifications and consequences are still not completely understood. In this study, we aim at improving water retention and hydraulic conductivity curves using both classical soil techniques and X-ray microtomography in the context of tillage simplification. We show a good match for retention and conductivity functions between macroscopic measurements and microtomographic information. Microtomography highlights the presence of a secondary pore system. Analysis of structural parameters for these pores appears to be significant and offers additional clues for objects differentiation. We show that relatively fast scans supply not only good results, but also enhance near saturation characterization, making microtomography a highly competitive instrument for routine soil characterization.

Fatéma Hal, ethnologue et restauratrice marocaine, décrit la nourriture, ainsi que la parole, comme ultime possession dont on ne peut jamais se défaire. On est ce qu’on mange, où qu’on soit. Mais on peut pousser l’analyse au-delà de cela, en affirmant que c’est encore à travers le goût qu’on connait l’autre. Qu’il s’agisse d’ « exotisme culinaire » (Régnier 2004) ou de ce que l’on pourrait définir comme un « cannibalisme exogène », la dégustation des cuisines ainsi dites « ethniques » est une pratique à la mode. Manger l’Autre, pour le connaître ou pour le contrôler ; se faire manger par l’Autre, pour raconter de soi ou pour satisfaire les discours sur l’intégration, témoignent du rôle complexe de la nourriture dans les rapports humains à travers les cultures. L’étude ethnographique que je présente dans cet article vise à illustrer comment certaines femmes marocaines vivant en Italie construisent un savoir culinaire commun, fait de pratiques et de saveurs mobiles, et de quelle façon ce même savoir est acteur du domaine publique.

Clustering procedures allowing for general covariance structures of the obtained clusters need some constraints on the solutions. With this in mind, several proposals have been introduced in the literature. The TCLUST procedure works with a restriction on the "eigenvalues-ratio" of the clusters scatter matrices. In order to try to achieve robustness with respect to outliers, the procedure allows to trim off a proportion of the most outlying observations. The resistance to infinitesimal contamination of the TCLUST has already been studied. This paper aims to look at its resistance to a higher amount of contamination by means of the study of its breakdown behavior. The rather new concept of restricted breakdown point will demonstrate that the TCLUST procedure resists to a proportion of contamination equal to the trimming rate as soon as the data set is sufficiently "well clustered".

Chronic kidney disease (CKD) is a major issue in public health. Its prevalence has been calculated using estimation of glomerular filtration rate (GFR) by the creatinine-based equations developed in the Modified Diet in Renal Disease (MDRD) and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) study. Recently, new equations based either on cystatin C (CKD-EPI Cys) or both cystatin and creatinine (CKD-EPI mix) have been proposed by the CKD-EPI consortium. The aim of this study was to measure the difference in the prevalence of stage 3 CKD, defined as an estimated GFR less than 60 mL/min/1.73 m2, in a population using these four equations. METHODS: CKD screening was performed in the Province of Liege, Belgium. On a voluntary basis, people aged over 50 years have been screened. GFR was estimated by the four equations. Stage 3 CKD was defined as a GFR less than 60 mL/min/1.73 m2. RESULTS: The population screened consisted of 4189 people (47% were men, mean age 63 +/- 7y). Their mean serum creatinine and plasma cystatin C levels were 0.88 +/- 0.21 mg/dL and 0.85 +/- 0.17 mg/L, respectively. The prevalence of CKD in this population using the MDRD, the CKD-EPI, the CKD-EPI Cys and the CKD-EPI mix equations was 13%, 9.8%, 4.7% and 5%, respectively. The prevalence of CKD was significantly higher with the creatinine-based (MDRD and the CKD-EPI) equations compared to the new cystatin C-based equations. CONCLUSIONS: Prevalence of CKD varies strongly depending on the method used to estimate GFR. Such discrepancies are of importance and must be confirmed and explained by additional studies, notably by studies using GFR measured with a reference method [less ▲]

The aim of this study is to compare the effect of different homogenization treat- 12 ments on the physicochemical properties and the hydrolysis rate of a pure bleached 13 cellulose. Results obtained show that homogenization treatments improve the enzymatic 14 hydrolysis rate of the cellulose fibers by 25 to 100 %, depending of the homogenization 15 treatment applied. Characterization of the samples showed also that homogenization had an 16 impact on some physicochemical properties of the cellulose. For moderate treatment inten- 17 sities (pressure below 500 b and degree of homogenization below 25), an increase of water 18 retention values (WRV) that correlated to the increase of the hydrolysis rate was highlighted. 19 Result also showed that the overall crystallinity of the cellulose properties appeared not to be 20 impacted by the homogenization treatment. For higher treatment intensities, homogenized 21 cellulose samples developed a stable tridimentional network that contributes to decrease 22 cellulase mobility and slowdown the hydrolysis process.

Flowering pattern, reproductive stage period (flowering, peg production, pod production and seed maturation) and efficiency of each stage for mature fruit production of two Arachis pintoi ecotypes (CIAT 17434 and CIAT 18744) were investigated in West Africa. Plants were sown in a randomized complete block design with four replicates per ecotype. Data collected over 3 years were analyzed with ANOVA. First flowers appeared on average 26 and 45 d after sowing for CIAT 17434 and CIAT 18744, respectively. Pegs began to extend about 8 and 18 d after anthesis; pod initiation about 22 and 40 d after anthesis and seed fully matured about 85 and 120 d after anthesis, respectively. CIAT 17434 produced (2269 flowers/plant) significantly (p≤0.05) more flower than CIAT 18744 (761 flowers/plant) during 7 months flowering. Conversely, flower efficiency for peg production was significantly (p≤0.05) higher for CIAT 18744 (8.14%) than for CIAT 17434 (4.02%). From 85 to 97% of pegs produced pods for both ecotypes. This research showed clearly that the principal constraint for effective seed production in particular ecological conditions of West Africa was the quite low efficiency of flowers for pegs production.

BACKGROUND: Ferulic acid esterified with poly(ethylene glycol) with three different average molecular weights (200, 400 and 1000 g/mol) was studied in breadmaking. The effects of these antioxidants on the properties of wheat flour dough and bread were analyzed and compared with those obtained with ferulic acid and two commercial surfactants, diacetyl tartaric acid ester of mono- and diglycerides and sodium stearoyl lactylate. Farinographic and alveographic methods as well as weight, volume and bread firmness measurements were used for this purpose. <br /> <br />RESULTS: Such as ferulic acid, when the PEGylated derivatives were implemented in the dough (5000 ppm), it accelerated its breakdown and decreased its rheological properties. However, it allowed to avoid the important diminution of loaf volume observed when dough supplemented with ferulic acid was baked. That decrease in volume was related to the inhibition of the yeast (Saccharomyces cerevisae) by the unesterified ferulic acid. Moreover, two of the PEGylated ferulic acids even contributed to an increase of loaf volumes (5-6%) and demonstrated crumb softener properties. <br /> <br />CONCLUSION: The addition of ferulic acid in wheat flour dough caused the inhibition of the yeast, which resulted in decreased bread volume. That effect could be avoid by the esterification of ferulic acid with poly(ethylene glycol). [less ▲]

Context. HD 150136 is a triple hierarchical system and a non-thermal radio emitter. It is formed by an O3-3.5 V + O5.5-6 V close binary and a more distant O6.5-7 V tertiary. So far, only the inner orbital properties have been reliably constrained. Aims. To quantitatively understand the non-thermal emission process, accurate knowledge of the physical and orbital properties of the object is crucial. Here, we aim to investigate the orbital properties of the wide system and to constrain the inclinations of the inner and outer binaries, and with these the absolute masses of the system components. Methods. We used the PIONIER combiner at the Very Large Telescope Interferometer to obtain the very first interferometric measurements of HD 150136. We combined the interferometric observations with new and existing high resolution spectroscopic data to derive the orbital solution of the outer companion in the three-dimensional space. Results. The wide system is clearly resolved by PIONIER, with a projected separation on the plane of the sky of about 9 milli-arcsec. The best-fit orbital period, eccentricity, and inclination are 8.2 yr, 0.73 and 108 degr. We constrain the masses of the three stars of the system to 63 +/- 10, 40 +/- 6, and 33 +/- 12 Msun for the O3-3.5 V, O5.5-6 V and O6.5-7 V components. Conclusions. The dynamical masses agree within errors with the evolutionary masses of the components. Future interferometric and spectroscopic monitoring of HD 150136 should allow one to reduce the uncertainties to a few per cent only and to accurately constrain the distance to the system. This makes HD 150136 an ideal system to quantitatively test evolutionary models of high-mass stars as well as the physics of non-thermal processes occurring in O-type systems. [less ▲]

Tree species can influence nutrient return to the forest floor and nutrient cycling through the amount and chemical composition of throughfall and litter. We compared foliar nutrient concentrations, litter production, nutrient return and soil chemistry under 7 tree species planted on the same site after two generations of a Norway spruce (Picea abies (L.) Karst.) monoculture. Common alder (Alnus glutinosa (L.) Gaertn.), european beech (Fagus sylvatica L.), pedunculate oak (Quercus robur L.), silver birch (Betula pendula Roth.), goat willow (Salix caprea L.) and rowan (Sorbus aucuparia L.) were planted within an experimental catchment on poor acid soil in south-eastern Belgium. Measurements were performed during one year, 11 years after planting. This study demonstrated that Ca, Mg, K and N concentrations in foliage and leaf litter are tree-species specific. Fresh foliage and foliar litter N concentrations were highest in alder and willow, while Ca, Mg and K concentrations were highest in rowan. Litter Ca concentrations were approximately twice in rowan than those of all other species. Differences in nutrient concentrations between foliage and leaf litter depended both on the element concerned and on tree species. The total average litterfall biomass ranged from 615 kg ha−1 year−1 under oak to 3122 kg ha−1 year−1 under rowan. Foliar litterfall represented above 85% for beech, spruce and oak, 70% for alder and willow and ca. 55% for birch and rowan. Reproductive parts formed 44% of total litterfall biomass under rowan. Ca, Mg, K and N return via throughfall, foliar litter and reproductive parts were higher under accompanying tree species (alder, birch, willow, rowan) than under the main commercial tree species (oak, beech, spruce). Total N return was in the order of 50 kg ha−1 year−1 under accompanying species, 33 kg ha−1 year−1 under spruce and near 20 kg ha−1 year−1 under beech and oak. Under rowan, total Ca, Mg, and K return to the forest floor through throughfall deposition, litterfall of leaves and reproductive parts amounted to 47, 9 and 66 kg ha−1 year−1, respectively. Compared to spruce, forest floor pHH20 has increased by 0.4 unit under birch and rowan, and exchangeable Ca2+, Mg2+, K+ have increased about threefold under rowan. Planting rowan as accompanying species may therefore represent an interesting management option for improving forest floor chemistry on nutrient poor sites through Ca, Mg, and K nutrient return.

In the last three decades, the development of the artisanal and small-scale mining (ASM) sector has been increasing in the Democratic Republic of Congo (DRC), bringing more and more urban families into this flourishing business sector, and among them, children. At first glance, one could see children in the mining sector mainly as victims entangled in the flows of raw materials of unbridled capitalism. But this paper aims to look at the often unconceivable, and as a result neglected, social agency of children even when they are involved in stigmatized and prohibited types of child labour. To do so, it relies on the results of a socio-anthropological collective research project on children’s mining activities which was carried out in a small locality called La Ruashi in the city of Lubumbashi (Province of Katanga). The article aims to provide a more comprehensive understanding of what is often normatively only labelled as ‘child labour’ by looking at different spheres of social relations within which children are embedded. Examining the set of social interactions that children have with their families, the broader community and their ‘peers’, several ‘family portraits’ are offered, highlighting a heterogeneity of social interpretations regarding this ‘new’ form of child work. It will be shown that for families from middle-class background, this kind of work is often socially disruptive, at the forefront of inter-generational conflict. As for families from lower classes, social changes induced by children’s mining activities are often better incorporated into the family habitus. Common social changes encountered in all families irrespective of class belonging will also be portrayed, showing the transversal societal impact these ‘new’ forms of child economic activities can provoke at a micro level.

This article presents a study of the use of the Dutch cardinal posture verbs staan (‘stand’), liggen (‘lie) and zitten (‘sit’) by French-speaking learners of Dutch; the data is drawn from a corpus of semi-spontaneous oral picture descriptions. Due to the typological differences between French and Dutch in the spatial domain (see Talmy 2000; Lemmens & Slobin 2008), the use of posture verbs is a highly problematic subject for French-speaking learners of Dutch. As a result, their interlanguage is typically characterized by an overall underuse of posture verbs as well as a confusion of the different posture verbs. Our study evaluates how the use of the posture verbs by the learners aligns with their level of proficiency. Strikingly, the statistical tendencies in our data show that a higher proficiency does not correspond to a more accurate use of posture verbs. At first sight, this seems to suggest that advanced learners have become worse at the use of posture verbs. A more refined analysis, however, shows that despite the increase of errors, the learners adopt more native-like strategies as their level of foreign language proficiency increases, suggesting that they gradually become more aware of the strong locative character of Dutch.

A previous study highlighted the effect of vocal technique on the singing voice accuracy of trained singers (1). The intervals' precision between the notes of the tune was altered when the singers used Western operatic singing technique. In order to better understand these results, we have recorded two different melodies sung with two different vocal techniques. A large panel of trained singers (N = 50) participated in the study. The analytical method described in the reference paper (1) has been applied. The results confirm the effect of vocal technique on the vocal accuracy of trained singers. In addition, these results provide an answer about the melodic effect and guide future work on the perception process of operatic voices. [less ▲]

In bilinear R-parity violation (BRpV), in which the superpotential includes a bilinear term between the lepton doublet and the up-type Higgs superfields, a sneutrino LSP can decay into pairs of heavy standard model states: W's, Z's, tops or Higgs bosons. These finals states can dominate over the traditionally considered bottom pair final state. This would lead to unique and novel supersymmetric signals with each supersymmetric event possibly producing two pairs of these heavy standard model fields. We investigate this possibility and find that the branching ratio into heavier states dominates when the bilinear term is much smaller than the sneutrino vacuum expectation value for a given sneutrino flavor. When BRpV is the only source of neutrino masses these decays can only dominate for one of the sneutrino generations. Relaxing this constraint opens these channels for all three generations. [less ▲]

Objective: Alcohol dependent patients (ADs) are known to encounter severe interpersonal problems. Nonverbal communication skills are important for the development of healthy relationships. The present study aimed to explore emotional facial expression (EFE) recognition and posed and spontaneous EFE expressivity in male ADs divided into two groups according to Cloninger’s typology and the impact of their interpersonal relationship quality on the potential nonverbal deficits. Method: Twenty type I ADs, twenty-one type II ADs, and twenty control participants took part in an EFE recognition task and an EFE expressivity task that considered personal emotional events (spontaneous expressivity) and EFE in response to a photo or word cue (posed expressivity). Coding was based on judges’ ratings of participants’ emotional facial expressions. Participants additionally completed a questionnaire on interpersonal relationship quality. Results: No difference between the three groups emerged in the EFE recognition task. Type II ADs showed heightened deficits compared with type I ADs in EFE expressivity: Judges perceived less accurate posed EFE in response to a cue word and less intense and positive spontaneous EFE in type II ADs compared to control participants. In addition, type II ADs reported more relationship difficulties compared to both type I ADs and control participants. These interpersonal relationship difficulties were related to some of the EFE expressivity deficits of AD-IIs. Conclusions: This study underlines the important differences between the interpersonal functioning of AD subtypes. [less ▲]

Many previous works involving physical models, excised and in vivo larynges have pointed out nonlinear vibration in vocal folds during voice production. Moreover, theoretical studies involving mechanical modeling of these folds have tried to gain a profound understanding of the observed nonlinear phenomena. In this context, the present work uses the nonlinear normal mode theory to investigate the nonlinear modal behavior of 16 subjects using a two-mass mechanical modeling of the vocal folds. The free response of the conservative system at different energy levels is considered to assess the impact of the structural nonlinearity of the vocal fold tissues. [less ▲]

This paper presents a method to compute accurate bounds on Jacobian determinants of high-order (curvilinear) triangular nite elements. This method can be used to guarantee that a curvilinear triangle is geometrically valid, i.e., that its Jacobian determinant is strictly positive everywhere in its reference domain. It also provides an e cient way to measure the quality the triangles. The key feature of the method is to expand the Jacobian determinant using a polynomial basis, built using B ezier functions, that has both properties of boundedness and positivity. Numerical results show the sharpness of our estimates. [less ▲]

A two-scale model predicting the mechanical behavior of nanocrystalline solids

Polycrystalline materials, with nanosized grains (<100 nm), exhibit superior strength exceeding those of their coarse-grained counterparts. With such small grains, the deformation mechanisms taking place at grain boundaries (GBs) become dominant compared to the intragranular crystal plasticity. Recent studies have revealed that the deformation mechanisms are influenced by the GB network. For instance, a high yield stress in nanostructured metals can be obtained by choosing the relevant grain boundary character distribution (GBCD). In this paper we present an original numerical multiscale approach to predict the mechanical behavior of nanostructured metals according to their GBCD composed of either high angle (HA) GBs (HAB) or low angle (LA) GBs (LAB). Molecular simulations using the quasicontinuum method (QC) are performed to obtain the mechanical response at the nanoscale of GB undergoing simple shear (GB sliding behavior) and tensile loads (GB opening behavior). To simulate the grain behavior, a mechanical model of dislocation motions through a forest dislocation is calibrated using a nanoindentation simulation performed with QC. These QC results are then used in a finite element code (direct numerical simulation-DNS) as a GB constitutive model and as a grain constitutive model. This two-scale framework does not suffer from length scale limitations conventionally encountered when considering the two scales separately. [less ▲]

Watershed management and hydrological modeling require data related to the very important matter of precipitation, often measured using raingages or weather stations. Hydrological models often require a preliminary spatial interpolation as part of the modeling process. The success of spatial interpolation varies according to the type of model chosen, its mode of geographical management and the resolution used. The quality of a result is determined by the quality of the continuous spatial rainfall which ensues from the interpolation method used. The objective of this article is to review the existing methods for interpolation of rainfall data that are usually required in hydrological modeling. We review the basis for the application of certain common methods and geostatistical approaches used in interpolation of rainfall. Previous studies have highlighted the need for new research to investigate ways of improving the quality of rainfall data and ultimately, the quality of hydrological modeling. [less ▲]

The foraging behaviour of a parasitoid insect species includes the host’s habitat and subsequent location of the host. Habitats-substrate, substrate moisture and light levels can affect the host location made by different species of parasitoids. However, the depth at which parasitoids concentrate their search effort is an another important ecological characteristic and play an important role on the host location. Here, we have investigated the ability of a pupal parasitoid, Nasonia vitripennis Walker, to penetrate and kill fly pupae located at different depth of the substrate. Three different types of substrate were tested: loam soil, compost and vermiculite substrate. In both loam soil and compost, all of the parasitism activity was restricted to pupae placed directly on the surface. Parasitism activity in vermiculite showed that the average number of pupae parasitized was decreased with depth. These results suggest that fly pupae situated deeper in the substrate are less subjected to parasitism by N. vitripennis. [less ▲]

In this paper, we examine how subjectivity helps to bridge the gap between grammatical description and textual analysis. Since Benveniste, subjectivity has become a central issue in linguistic investigation: while the French linguist set the ground from which subjectivity could emerge as a linguistic issue, he also opened a wide and non-systematic range of terminological possibilities, between philosophy and grammar. From this ground, followers such as Kerbrat-Orecchioni, Coquet, Langacker and Traugott have designed peculiar approaches and — significantly divergent — avenues for future research. The present study investigates these five theoretical frameworks in which, between text and grammar, the term subjectivity holds a place of paramount significance. [less ▲]

The last two decades have witnessed a growing interest in theorizing literary narratives that address the South Asian diasporic experience. By and large, however, what has emerged is an academic consensus which accords an ever-greater visibility to mainstream diasporic voices from North America, U.K., some parts of Africa and of the Caribbean, at the expense of narratives dealing with South Asian diasporic communities that are based in other locations. Also, such critical consensus valorizes certain class-streamed patterns of migration over others, with the result of homogenizing the diversity of today’s South Asian diaspora. This special issue explores literary representations of the migrant experiences of those underrepresented South Asian communities based in locations such as South America, East Europe, the Gulf, West Africa and East Asia.

Many contaminants can attach to suspended particles. Their transport differs therefore from the transport of dissolved substances, especially in highly turbid environment like estuaries. In this paper, we show how the Constituent Age and Residence time Theory (CART — www.climate.be/CART) can be adapted to quantify in a rigorous manner the transport rate of contaminants that are present in both the dissolved and adsorbed phases. On the basis of numerical experiment using a 1D model of the Scheldt estuary, it is shown that the interaction with suspended particles significantly affects the transport of contaminants with partition coefficients larger than 1000 ml/g. The mean transit time from Ghent to Vlissingen of such contaminants can reach 160 days while it is only 60 days for water and dissolved constituents. This increase of the transit time is mainly due to the fact that adsorbed constituents spend long periods of time on the bottom. Surprisingly, the downstream transport of adsorbed constituents in the water column appears more effective than that of dissolved constituents. This transport affects however a small fraction of the adsorbed constituent and is therefore not sufficient to compensate for the long resting phase on the bottom of the bulk of the constituent. The concept and methodology introduced in this paper are easily applicable to most model studies and provide powerful and flexible tools for the detailed understanding of the transport of contaminants in estuaries. In particular, the concept of age and modified ages taking into account specifically the time spent in the water column or in the bottom provide new diagnostic tools to understand and quantify the dynamics of contaminants.
