WVO Quine questions the « myth » of an ideal realm of shared meanings which every national language would express in its own way. Against the hope of transparent translations, he insists on the necessity for building equivalences from one language to another through a strategy of reducing the differences in rationality among nations as much as possible. According to Quine, otherness is not insuperable impediment to meeting/encounter and mutual understanding ; by throwing our conceptual schemes on the other communities’ uses/practices – which of course involves some symbolic violence – gaps can always been narrowed. Similarly E. Laclau questions the traditional conception of political representation, which is seen as the transparent process of transmitting someone’s will or interests on another level. For this ideal conception of representation, Laclau substitutes a pragmatic conception which takes in account the irreducible gap between the actors as well as the constitutive opacity of the process of representation : the subject’s will is constituted within the process of representation and through the representative’s productive role. In order to be transposed at the decision-making level, the subject’s interests must be translated by the representative as well as be negotiated with the other represented interests. This implies that the initial will undergoes some identity transformations. [less ▲]

In this letter, we show how a simple motion-guided nonlinear filter can drastically improve the accuracy of several pedestrian detectors. More specifically, we address the problem of how to pre-filter an image so almost any pedestrian detector will see its false detection rate decrease. First, we roughly identify moving pixels by cumulating their temporal gradient into a motion history image (MHI). The MHI is then used in conjunction with a nonlinear filter to filter out background details while leaving untouched foreground moving objects. We also show how a feedback loop as well as a merging procedure between the filtered and the unfiltered frames can further improve results. We tested our method on 26 videos from 6 categories. The results show that for a given miss rate, filtering out background details reduces the false detection rate by a factor of up to 69.6 times. Our method is simple, computationally light, and can be implemented with any pedestrian detector. Code is made publicly available at: https://bitbucket.org/wany1601/pedestriandetection. [less ▲]

Applications of timelapse inversion of electrical resistivity tomography (ERT) allows monitoring variations in the subsurface that play a key role in a variety of contexts. The inversion of timelapse data provides successive images of the subsurface properties showing the medium evolution. Images quality is highly dependent on the data weighting determined from the data error estimates. However, the quantification of errors in the inversion of timelapse data has not yet been addressed. We propose a methodology for the quantification of timelapse data error based on the analysis of the discrepancy between normal and reciprocal readings acquired at different times. We apply the method to field monitoring data sets collected during the injection of heated water in a shallow aquifer. We tested different error models to show that the use of an appropriate time-lapse data error estimate yields significant improvements in terms of imaging. An adapted inversion weighting for time-lapse data implies that the procedure does not allow an over-fitting of the data, so the presence of artifacts in the resulting images is greatly reduced. Our results demonstrate that a proper estimate of time-lapse data error is mandatory for weighting optimally the inversion in order to obtain images that best reflect the medium properties evolution through time.

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 ▲]

Resolving population genetic structure is challenging, especially when dealing with closely related populations. Although Principal Component Analysis (PCA)-based methods and genomic var- iation with single nucleotide polymorphisms (SNPs) are widely used to describe shared genetic an- cestry, improvements can be made targeting fine-level population structure. This work presents an R package called IPCAPS, which uses SNP information for resolving possibly fine-level population structure. The IPCAPS routines are built on the iterative pruning Principal Component Analysis (ipP- CA) framework to systematically assign individuals to genetically similar subgroups. Our tool is able to detect and eliminate outliers in each iteration to avoid misclassification. It can be extended to de- tect subtle subgrouping in patients as well. In addition, IPCAPS supports different measurement scales for variables used to identify substructure. Hence, panels of gene expression and methylation data can be accommodated. [less ▲]

We introduce the concept of constant 2-labelling of a vertex-weighted graph and show how it can be used to obtain perfect weighted coverings. Roughly speaking, a constant 2-labelling of a vertex-weighted graph is a black and white colouring of its vertex set which preserves the sum of the weights of black vertices under some automorphisms. We study constant 2-labellings on four types of vertex-weighted cycles. Our results on cycles allow us to determine (r, a, b)-codes in Z^2 whenever |a−b|>4, r>1 and we give the precise values of a and b. This is a refinement of Axenovich’s theorem proved in 2003.

We describe a robust platform for the synthesis of a large diversity of novel functional CO2 -sourced polymers by exploiting the regio-controlled and site selective ring-opening of α- alkylidene carbonates by various nucleophiles. The remarkable reactivity of α-alkylidene carbonates is dictated by the exocyclic olefinic group that selectively orients the cyclic carbonate ring- opening with the formation of an enol species. The polyaddition of CO2 -sourced bis-α-alkylidene carbonates (bis-αCCs) with primary and secondary diamines provides novel regioregular functional poly(urethane)s. The reactivity of bis-αCCs is also exploited for producing new poly(β-oxo-carbonate)s by organocatalyzed polyaddition with a diol. All polyadditions were feasible under ambient conditions. This synthesis platform provides new functional variants of world-class leading polymers families (polyurethanes, polycarbonates) and valorises CO2 as a chemical feedstock. [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.

A nitrogen (N) balance digestion trial was conducted to determine the protein requirement of collared peccaries (Pecari tajacu). In a 4 × 4 Latin square design, four captive adult male peccaries were fed four isoenergy diets containing four different levels of N (11.7, 16.3, 22.8, and 26.7 g N/kg of dry matter—DM). After 15 days of adaptation, a total collection of feces and urine was carried out for five consecutive days. Regression analyses between N intake and N in feces and urine allowed to calculate the metabolic fecal nitrogen (MFN = 2.3 g N/kg of dry matter intake—DMI) and daily endogenous urinary N (EUN = 185 mg N/kg0.75). Likewise, by regression analyses between consumption of nitrogen and the nitrogen balance (NB = N ingested − N excreted, mg N/kg0.75), a daily requirement of 514 mg N/kg0.75 was calculated. Therefore, if food intake is unrestricted, collared peccaries require a minimumin their diet of about 5.4% crude protein on DM basis. These values are almost as low as those found for browsing and frugivorous wild ruminants, which reinforce the proposition that peccaries’ digestive physiology is nearer to that of domestic and wild ruminants than domestic pigs. This relatively low protein requirement of collared peccary and its great ability to digest protein reveal the relevance of the forestomach for the species on nitrogen/protein metabolism and allow the use of diets with lower crude protein levels than the commercial ones used for the domestic pig, which reduces feed costs.

Proteomic approach was applied to identify total proteins, particularly the enzymatic content, from wild cardoon flowers. As the selection of an appropriate sample preparation method is the key for getting reliable results, two different extraction/precipitation methods (trichloroacetic acid and phenol/ammonium acetate) were tested on fresh and lyophilized flowers. After two-dimensional electrophoresis (2D–E) separations, a better protein pattern was obtained after phenol extraction from lyophilized flowers. Only 46 % of the total analyzed spots resulted in a protein identification by mass spectrometry MALDI-TOF. Four proteases (cardosins A, E, G, and H), which have become a subject of great interest in dairy technology, were identified. They presented molecular weights and isoelectric points very close and high levels of homology between matched peptides sequences. The absence of the other cardosins (B, C, D, and F) could be an advantage, as it reduces the excessive proteolytic activity that causes bitter flavors and texture defects, during cheese making.

Aphids are frequently engaged in mutualistic associations with endosymbionts. Symbionts are bacterial or fungal microorganisms that can be obligate or facultative to aphids. Research showed facultative (or secondary) symbionts have numerous effects on their host aphids such as resistance to heat shock, parasitoids and fungus etc., which may consequently promote a co-evolution between symbionts and hosts. However, this symbiotic relation may be affected by several factors, such as the ability of symbionts to spread from aphids to others within and across populations, and the cost of infections for hosts. Moreover, aphid-symbionts interactions may be affected by aphid living environment such as its host plant, the presence of natural enemies or the temperature. Here we firstly described the functions of nine facultative symbionts (Serratia symbiotica, Hamiltonella defensa, Regiella insecticola, Rickettsia, Rickettsiella, PAXS (pea aphid X-type symbiont), Spiroplasma, Wolbachia and Arsenophonus) studied in aphids one by one, and discussed the associations between these symbionts and aphids, plants and environment. We aim to have a better knowledge of the roles the facultative symbionts play in aphid biology, ecology and evolution, which we believe can provide new inspirations for aphid control. [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 ▲]

In this paper I want to create a presumption in favor of a nonreductive analysis of emotional phenomenology. The presumption relies on the claim that none of the nonemotional elements which are usually regarded as constitutive of emotional phenomenology may reasonably be considered responsible for the evaluative character of the latter. In section 1 I suggest this is true of cognitive elements, arguing that so-called ‘evaluative’ judgments usually result from emotional, evaluative attitudes, and should not be conflated with them. In section 2 I argue the same holds true for conative attitudes (desires and acts of the will). And in section 3 I briefly mention some salient aspects of the version of nonreductive analysis I lean toward. [less ▲]

The famous Doignon-Bell-Scarf theorem is a Helly-type result about the existence of integer solutions to systems of linear inequalities. The purpose of this paper is to present the following quantitative generalization: Given an integer k, we prove that there exists a constant c(n,k), depending only on the dimension n and on the number k, such that if a bounded polyhedron {x in R^n : Ax <= b} contains exactly k integer points, then there exists a subset of the rows, of cardinality no more than c(n,k), defining a polyhedron that contains exactly the same k integer points. In this case c(n,0)=2^n as in the original case of Doignon-Bell-Scarf for infeasible systems of inequalities. We work on both upper and lower bounds for the constant c(n,k) and discuss some consequences, including a Clarkson-style algorithm to find the l-th best solution of an integer program with respect to the ordering induced by the objective function.

This paper focuses on the interpolation of the kinematic fields describing the configuration of geometrically exact beams, namely, the position and rotation fields. Two kinematic representations are investigated: the classical approach that treats the displacement and rotation fields separately and the motion approach that treats those two fields as a unit. The latter approach is found to be more consistent with the kinematic description of beams. Then, two finite element interpolation strategies are presented and contrasted. The first interpolates the displacement and rotation fields separately, whereas the second interpolates both fields as a unit, in a manner consistent with the motion approach. The performance of both strategies is evaluated in light of the fundamental requirements for the convergence of the finite element method: the ability to represent rigid-body motions and constant strain states. It is shown that the traditional uncoupled interpolation scheme for the position field approximates that based on the motion approach and that the coupling induced by the interpolation of motion yields superior convergence rates for the representation of constant strain states. This property is known to lead to finite elements that are less prone to the locking phenomenon. [less ▲]

In this paper, numerical and experimental investigations devoted to the evaluation of the bearing resistance of tubular members with gusset plates and through-all long bolts are presented. Unlike lap shear joints, the analysed connection evidences a reduced confinement of the bearing area associated to the use of long bolts and the presence of a gap in the member, which can lead, consequently, to a reduction of the bearing resistance. In order to investigate the behaviour of shear connections made up of thin and thick SHS (Square Hollow Section) profiles and long bolts, an experimental test campaign including 24 specimens and FE simulations have been conducted. Both experimental and FE results have confirmed the influence of local instability on the hole in bearing resistance of thin profiles and the poor accuracy of the available standards for this particular joint typology. In particular, the performed comparisons have shown that, for thin profiles, EC3 model is likely to overestimate the resistance, while for higher thickness of the SHS conservative predictions are obtained. The present paper presents the conducted experimental and numerical investigations, highlighting at the end the need for a proper formulation able to account for the local instability effect on the bearing resistance.

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.

Objectives: To describe the mean voice changes of 22 female teachers during a typical workday, examine the inter- and intra-subject variability, and establish a typology of different voice patterns during the workday. Methods: For each participant, fundamental frequency (F0), harmonics-to-noise ratio (HNR), jitter, and shimmer were measured on sustained vowels at the beginning and at the end of the workday, at three different times during the school year. Results: The group mean pattern showed significant increases in F0 and HNR during the workday and significant decreases in jitter and shimmer. However, considerable inter- and intra-subject variability was observed. Based on the variation in the acoustic parameters during the workday, three different voice patterns were identified. The first is characterized by a greater F0 increase during the day, interpreted as a common, appropriate adaptation to vocal load. The second is characterized by a greater increase in HNR during the day and greater decreases in jitter and shimmer, interpreted as hyperfunctional voice production. The third is characterized by greater decreases in F0 and HNR and greater increases in jitter and shimmer, suggesting acute inflammation or muscle fatigue following the workday. Conclusions: The observed variety of vocal patterns during the workday emphasizes the need to study this phenomenon individually and target different types of behaviors in order to develop tailored prevention and treatment methods.

Allogeneic hematopoietic stem cell transplantation (SCT) contributes to improved outcome in childhood acute leukemia (AL). However, therapeutic options are poorly defined in case of post-transplantation relapse. We aimed to compare treatment strategies in 334 consecutive children with acute leukemia relapse or progression after SCT in a recent ten-year period. Data could be analyzed in 288 patients (157 ALL, 123 AML and 8 biphenotypic AL) with a median age of 8.16 years at transplantation. The median delay from first SCT to relapse or progression was 182 days. The treatment consisted in chemotherapy alone (n=108), chemotherapy followed by second SCT (n=70), supportive/palliative care (n=67), combination of chemotherapy and DLI (n=30), or isolated reinfusion of donor lymphocytes (DLI) (n=13). The median OS duration after relapse was 164 days and differed according to therapy: DLI after chemotherapy = 385 d, second allograft = 391d, chemotherapy = 174d, DLI alone = 140d, palliative care = 43d. A second SCT or a combination of chemotherapy and donor lymphocytes infusion yielded similar outcome (HR=0.85, p=0.53) unlike chemotherapy alone (HR 1.43 p=0.04), palliative care (HR=4.24, p<0.0001) or isolated DLI (HR=1,94, p<0.04). Despite limitations in this retrospective setting, strategies including immunointervention appear superior to other approaches, mostly in AML. [less ▲]

Cabbage (Brassica oleracea L.) is a common vegetable whose production is severely limited by insect pest pressure in Western Africa. This study was conducted during the dry and rainy season in the south Benin to evaluate the potential of tropical basil (Ocimum gratissimum L.) for repelling cabbage pests (Hellula undalis Fabricius, Plutella xylostella L. and Spodoptera litto-ralis Boisduval). In a complete randomized block design with four replicates, the insect infestation were compared between three association modalities: (i) cabbage intercropped with tropical basil, (ii) cabbage plots surrounded by tropical basil and (iii) control (no basil in the cabbage area). The presence of tropical basil near cabbage plots significantly reduced insect pest abundance on cabbage. Damages were also less important on cabbage intercropped with tropical basil. Among both intercropping modalities, alternate rows showed the best results in terms of reducing pest populations and damages than compared to cabbage plots surrounded by tropical basil. [less ▲]

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.

Allogeneic stem cell transplantation (allo-SCT) following a non-myeloablative (NMA) or reduced-intensity conditioning (RIC) is considered a valid approach to treat patients with refractory/relapsed Hodgkin lymphoma (HL). When an HLA-matched donor is lacking a graft from a familial haploidentical (HAPLO) donor, a mismatched unrelated donor (MMUD) or cord blood (CB) might be considered. In this retrospective study, we compared the outcome of patients with HL undergoing a RIC or NMA allo-SCT from HAPLO, MMUD or CB. Ninety-eight patients were included. Median follow-up was 31 months for the whole cohort. All patients in the HAPLO group (N = 34) received a T-cell replete allo-SCT after a NMA (FLU-CY-TBI, N = 31, 91%) or a RIC (N = 3, 9%) followed by post-transplant cyclophosphamide. After adjustment for significant covariates, MMUD and CB were associated with significantly lower GvHD-free relapse-free survival (GRFS; hazard ratio (HR) = 2.02, P = 0.03 and HR = 2.43, P = 0.009, respectively) compared with HAPLO donors. In conclusion, higher GRFS was observed in Hodgkin lymphoma patients receiving a RIC or NMA allo-SCT with posttransplant cyclophosphamide from HAPLO donors. Our findings suggest they should be favoured over MMUD and CB in this setting. [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.

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.

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 ▲]

Familial pituitary adenomas accounts for approximately 5-8 % of all pituitary adenomas. Besides the adenomas occurring as part of syndromic entities that bring together several endocrine or other systems disorders, 2-3% of the familial pituitary adenomas fit into the familial isolated pituitary adenomas (FIPA) syndrome. 20% of FIPA syndromes have shown mutations in the AIP gene and have distinct clinical characteristics. Recent findings have isolated a new non-AIP FIPA syndrome called X-LAG, resulting from duplication in GPR-101 gene. These new advances in the field of pituitary disease are opening up a new challenging domain to both clinician and researcher. This review will focus on these last findings and their contribution to the diagnosis and the management of familial pituitary adenomas. [less ▲]

This paper presents a novel equivalent, which is suitable for simulation of inertial and primary frequency control effects. In the model reduction procedure, dynamic power injectors are used to replace the external system and to mimic its dynamic behavior. The parameters of the equivalents are tuned with a simple approach presented in this paper. The effectiveness of the proposed method is demonstrated on a modified version of the ENTSO-E Dynamic Study Model. The results show that the system frequency response of the unreduced system is retained and a speedup of the simulations of around 4.0 is achieved. [less ▲]

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.

Platelet-rich plasma (PRP) is blood plasma with a high concentration of autologous platelets which constitute an immense reservoir of growth factors. The clinical use of PRP is widespread in various medical applications. Although highly popular with athletes, the use of PRP for the treatment of tendinopathies remains scientifically controversial, particularly due to the diversity of products that go by the name of “PRP.” To optimize its use, it is important to look at the various stages of obtaining PRP. In this literature review, we take a closer look at eight parameters which may influence the quality of PRP: 1) anticoagulants used to preserve the best platelet function, 2) the speed of centrifugation used to extract the platelets, 3) the platelet concentrations obtained, 4) the impact of the concentration of red and while blood cells on PRP actions, 5) platelet activators encouraging platelet degranulation and, hence, the release of growth factors, and 6) the use or nonuse of local anesthetics when carrying out infiltration. In addition to these parameters, it may be interesting to analyze other variables such as 7) the use of ultrasound guidance during the injection with a view to determining the influence they have on potential recovery.

Essential (Fe, Mo, Mn, Cr, Ni, Co) and non-essential (Ag, Pb, Sn) trace elements (TEs) were measured in liver, kidney, and brain samples of by-catch Franciscana dolphins that were living in estuarine (n = 21) and marine (n = 21) habitats (1) to assess whether TEs posed a threat and (2) to evaluate the suitability of TEs for discriminating ecological populations of this species in Argentinean waters. Essential TEs showed little variation in tissues from both groups in agreement with levels reported for other cetaceans and suggesting that these concentrations correspond to normal physiological levels. Non-essential TEs were higher in estuarine juveniles and adults dolphins than in marine specimens. These results suggest anthropogenic sources associated with estuarine area and that Franciscana dolphins are good sentinels of the impact of the environment. The difference in the concentrations of TEs beetwen ecological populations appeared to be related to distinct exposures in both geographical areas, and it is suggested that Ag and Sn concentrations in adults are good chemical tracers of anthropogenic input of TEs. These results provide additional information for improved management and regulatory policy. [less ▲]

Low-melting berry wax (BEW) has proven to be a good oil gelator with a positive contribution to the consistency and flexibility of the structured oil. Nevertheless, the properties of BEWand the corresponding oleogel have not yet been investigated in-depth. In this research, the difference in crystallization and gelling behavior between sunflower wax (SW), a high melting wax, and BEW, a low-melting wax, in rice bran oil (RBO) was investigated. The difference in melting and crystallization temperatures can be explained by the different chemical composition (long-chain wax esters in SWand shortchain fatty acids in BEW). The heterogeneity in crystal habits (unidirectional platelets versus microcrystalline particles) and polymorphism (orthorhombic versus hexagonal) are responsible for the varying gel strength and hardness of the respective SWand BEW-oleogels. The microcrystalline BEW particles aligned and reorganized during 1-month storage at 5 °C, which leaded to an increase in the gel strength and hardness of BEW-oleogel. The gelling property of SW-oleogel however did not significantly differ after 4 weeks at 5 °C, despite of the appearance of spherulitic crystalline clusters. The changes in the physical properties of wax-based oleogels during storage time were further explored using differential scanning calorimetry, polarized light microscope, powder X-ray diffraction and rheology.

¿Cómo el poeta de Las Flores del Mal paso de ser un autor proscrito, y en consecuencia sospechoso, al autor perseguido e incomprendido que ha inmortalizado la historia literaria? ¿Cómo Baudelaire pudo desviar a su favor una circunstancia que, a primera vista, era desafortunada? Baudelaire supo utilizar el escándalo que provocó la publicación de Las Flores del Mal para promover su figura pública. Un análisis de las posturas discursivas desplegadas por Baudelaire y por sus pares durante y después del proceso nos permitirá comprender mejor la inversión que el poeta hace de su condenación al transformar la sanción penal y moral, y la exclusión a la que ésta conduce, en un signo de su grandeza y de su gloria póstuma.

Dans le dernier quart du XVIe siècle, Philippe II d’Espagne est à la tête de l’ensemble territorial le plus puissant d’Europe. Fils préféré de l’Église romaine et souverain reconnu d’une grande partie de l’Italie, il exerce une influence considérable sur la papauté à travers l’action de son ambassadeur espagnol résidant près le Saint-Siège. Ce dernier a pour tâche d’étendre le réseau des alliés au sein de la Curie. Il chapeaute aussi les différents services diplomatiques et ecclésiastiques des États de la monarchie présents dans la cité des papes . Si elle conserve une certaine autonomie, la légation des Pays-Bas et de la Franche-Comté près le Saint-Siège – conduite par l’agent Laurent du Blioul de 1573 à 1598 – est également soumise à la volonté de cet envoyé. Ce n’est d’ailleurs pas un hasard si l’étude de la légation à l’époque du règne de Philippe II a peu passionné les historiens . Effacée derrière la puissance de l’ambassadeur espagnol, celle-ci semble être un piètre avatar des services ecclésiastiques et diplomatiques dépêchés à Rome par les ducs de Bourgogne , Philippe le Beau ou les archiducs Albert et Isabelle . Or, si, aux temps de Laurent du Blioul, la légation, considérée en tant qu’actrice isolée dans le paysage romain, joue un rôle modeste qui se cantonne au suivi des affaires ecclésiastiques provenant des Pays-Bas et de la Franche-Comté, il faut envisager qu’elle fait partie intégrante d’une toile religieuse, diplomatique, sociale et politique plus vaste tissée à Rome par le roi Philippe II et ses agents. Dépassant les seuls intérêts des Pays-Bas, l’étude de cette institution conduit à appréhender tout un pan de la stratégie politique habsbourgeoise. L’imbrication de la légation dans le théâtre diplomatique espagnol à Rome a deux facettes : si, d’une part, elle limite les prérogatives institutionnelles de l’agent du Blioul, d’autre part, elle favorise régulièrement l’efficacité de son action.

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.

Access-based services (ABS), which grant customers limited access to goods without any transfer of ownership, are unique technology-based service innovations requiring the substantial involvement and collaboration of customers, without employees’ supervision. Although ABS offer several potential advantages, convincing customers to use them remains challenging. Combining 56 in-depth interviews with supplementary literature, the authors address this challenge by proposing an integrative framework that reflects the (1) barriers that prevent customers from using ABS and (2) practices in which customers engage to attenuate those barriers. The complex, multidimensional barriers relate not only to the service and technology features but also to other customers. Customers can engage in different practices to attenuate perceived barriers and create value, namely, “to distance,” “to manage,” “to elaborate,” “to control,” and “to relate.” Yet they regard these barrier-attenuating practices as necessary sacrifices to use ABS. Complementing suggestions that customers adopt and use ABS to escape the burdens of ownership, the current research reveals that customers actually may confront several “burdens of access.” This research suggests managers who wish to reduce rejection of their innovation could not only overcome customers’ perceived barriers, but also facilitate and reduce the number of practices in which customers engage to attenuate those barriers themselves.

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.

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 ▲]

positively correlated with floating behavior on the third test. A twoweek- long pretreatment regime with imipramine (7.5 mg/kg/day) or thiamine (200 mg/kg/day), which is known to have antidepressant properties, reduced the GSK3β over-expression and decreased floating behavior on Day 5. GSK3α mRNA levels were measured in the hippocampus and prefrontal cortex on Days 1, 2 and 5. GSK3α expression was decreased in the prefrontal cortex on Day 2 and increased on Day 5. In this model, GSK3α mRNA changes were prevented by imipramine or thiamine treatment. There was a significant correlation between the expression of the two isoforms in the prefrontal cortex on Day 2 in untreated group. These results provide the first evidence for the potential involvement of GSK3α in depressive-like behaviours and as a target of anti-depressant therapy. Furthermore, the correlations suggest some cross-talk may exist between the two GSK3 isoforms. [less ▲]

Ion mobility-mass spectrometry (IM-MS) has emerged as a powerful separation and identification tool to characterize synthetic polymer mixtures and topologies (linear, cyclic, star-shaped,...). Electrospray coupled to IM-MS already revealed the coexistence of several charge state-dependent conformations for a single charge state of biomolecules with strong intramolecular interactions, even when limited resolving power IM-MS instruments were used. For synthetic polymers, the sample's polydispersity allows the observation of several chain lengths. A unique collision cross-section (CCS) trend is usually observed when increasing the degree of polymerization (DP) at constant charge state, allowing the deciphering of different polymer topologies. In this paper, we report multiple coexisting CCS trends when increasing the DP at constant charge state for linear poly(acrylamide) PAAm in the gas phase. This is similar to observations on peptides and proteins. Biomolecules show in addition population changes when collisionally heating the ions. In the case of synthetic PAAm, fragmentation occurred before reaching the energy for conformation conversion. These observations, which were made on two different IM-MS instruments (SYNAPT G2 HDMS and high resolution multi-pass cyclic T-Wave prototype from Waters), limit the use of ion mobility for synthetic polymer topology interpretations to polymers where unique CCS values are observed for each DP at constant charge state.

In liberalized network industries, competitors can either compete for service using the existing infrastructure (access) or deploy their own capacity (bypass). We revisit this make-or-buy problem making two contributions to the literature. First we analyze both the profit maximizing behavior of an incumbent and the welfare maximizing behavior when the entrant chooses between access and bypass. Second, we extend the baseline model studied in the literature by allowing for fixed costs of network installation. By analogy to the literature on strategic entry deterrence, we distinguish three regimes of blockaded bypass, deterred bypass and accommodated bypass depending on the entrant's unit cost. We show that the make-or-buy decision of the entrant is not necessarily technologically efficient: when bypass is chosen, it is always the cheapest option but access may be chosen when it is not cost effective.

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 ▲]

A two-level real-time voltage control scheme is proposed to keep voltages within specified limits in distribution grids using Distributed Generation Units (DGUs). It combines a local and a centralized control of their reactive powers. The local control provides fast response after a disturbance, reducing its impact and enhancing voltage quality. The centralized control uses measurements collected throughout the network to bring the voltages inside tighter limits and balance the various DGU contributions. To this purpose, it adjusts in a coordinated way their reactive power set-points, taking into account the local controls. This discrete control solves at each time step a multi-time-step constrained optimization inspired of Model Predictive Control. The method effectiveness is demonstrated on a 75-bus test system hosting 22 DGUs. [less ▲]

This retrospectivemulticenter study in patientswith chronic myeloid leukemia in chronic phasewas undertaken to confirm the clinical relevance of imatinib plasma concentrations monitoring in daily practice. Forty-one patients, with 47 imatinib plasma measurements, were analyzed during treatment with imatinib given at a fixed 400mg daily dose. A significant inverse relationship of imatinib concentration with the patients' weight was observed (Pearson's test: p=0.02,R2=0.1). More interestingly, patientswith poor response (switched to another tyrosine kinase inhibitor because of imatinib failure, or because of disease progression after an initial response) displayed a significantly lower mean imatinib concentration as compared to patients maintained on imatinib (822 ng/mL vs 1099 ng/mL; Student's t-test, p=0.04). Failure or disease progression occurred more often in patients in the lowest quartile of imatinib concentrations compared to patients in the highest quartile (p = 0.02, logrank test). No correlation could be established with other biological or clinical parameter, including complete cytogenic response and majormolecular response. In conclusion: in patients treatedwith imatinib at a fixed daily dose of 400 mg, imatinib plasma concentrations decreased with increasing body weight and were lower in patients switched to another tyrosine kinase inhibitor due to imatinib failure. Systematic determination of imatinib plasma trough levels should be encouraged in such patients. [less ▲]

Objectives: This paper aims to summarize the hypothesis, which originates in the field of phenomenological psychopathology, of schizophrenic hyperreflexivity, and to discuss the methodological context enabling these highly subjective manifestations to emerge. Starting from the seminal hypothesis developed by contemporary psychopathology, that the schizophrenic patients appear to experience a consciousness that finds itself being forced to question phenomena which should be intuitively self-evident, the idea of this present paper is to complete the usual interpretation of schizophrenia as deficit by the hypothesis of an excess functioning of consciousness. Methods: First-person perspective is a qualitative approach completing third-person interpretation, traditional in the field of psychiatry – which consists in the attribution, from an external position, of clinical signs noted independently of the perception expressed by the patient. This first-person perspective focuses on the subjective experience expressed by the individual. To understand schizophrenia according to this perspective, the words of several schizophrenic patients have been collected as part of a clinical device. We used the EASE scale (Examination of Anomalous Self-Experience) with this aim in mind. This scale offers a phenomenologically oriented semi-structured exploration of a set of difficulties revealing anomalies of subjective experience, considered as troubles of self-awareness. EASE has been developed on the basis of self-descriptions by patients suffering from schizophrenic spectrum troubles. This tool allows the co-construction of a language between patient and clinician, focused on the patient’s particular experience and the unique phenomena he endures. Results: Besides the hyperreflexivity phenomena, the qualitative analysis of collected descriptions highlight two important features of schizophrenic being-in-the-world. First a problem of common sense, which addresses the issue of intersubjectivity and the opportunity, for schizophrenic patients, to share a social world. Then the existence of an intercorporeality trouble, since the schizophrenic hyperreflexivity experiences are accompanied by a loss of “common body”, body being the scene where intersubjectivity is performed. Employing EASE, and the ensuing first-person perspective, is relevant in a psychotherapeutic approach; on one hand in the process of acknowledgement of the disease (which has to be made by the patient as well as by the clinician), on the other hand in the communication with families of schizophrenic patients. Conclusions: The phenomenological interpretation offered by the application of a first-person perspective in the understanding of schizophrenic patients experience, as well as the interest showed in the hyperreflexivity phenomenon, suggest an outlook of schizophrenia which isn’t reduced to a deficit interpretation anymore (without denying the latter), and which uncovers not a weakening, but a surprising intensification of consciousness.

Objectives: (1) To investigate music theory teachers’ professional and extra-professional vocal loading and background noise exposure, (2) to determine the correlation between vocal loading and background noise, and (3) to determine the correlation between vocal loading and self-evaluation data. Methods: Using voice dosimetry, 13 music theory teachers were monitored for one workweek. Parameters analysed were voice SPL, F0, phonation time, vocal loading index (VLI) and noise SPL. Spearman’s correlation was used to correlate vocal loading parameters (voice SPL, F0 and phonation time) and noise SPL. Each day, subjects self-assessed their voice using visual analogue scales. VLI and self-evaluation data were correlated using Spearman’s correlation. Results: Vocal loading parameters and noise SPL were significantly higher in the professional than in the extra-professional environment. Voice SPL, phonation time and females’ F0 correlated positively with noise SPL. VLI correlated with self-assessed voice quality, vocal fatigue and amount of singing and speaking voice produced. Conclusions: Teaching music theory is a profession with high vocal demands. More background noise is associated with increased vocal loading and may indirectly increase the risk for voice disorders. Correlations between VLI and self-assessments suggest that these teachers are well-aware of their vocal demands and feel their effect on voice quality and vocal fatigue. Visual analogue scales seem to represent a useful tool for subjective vocal loading assessment and associated symptoms in these professional voice users. [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 ▲]

However, while memory for the times of past events has been much investigated, little is known about how imagined future events are temporally located. Using a think-aloud protocol, we found that the temporal location of past and future events is rarely directly accessed, but instead mostly relies on reconstructive and inferential strategies. References to lifetime periods and factual knowledge (about the self, others, and the world) were most frequently used to determine the temporal location of both past and future events. Event details (e.g., places, persons, or weather conditions) were also used, but mainly for past events. Finally, the results showed that events whose temporal location was directly accessed were judged more important for personal goals. Together, these findings shed new light on the mechanisms involved in locating personal events in past and future times. [less ▲]

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 ▲]

This paper presents a Discontinuous Galerkin scheme in order to solve the nonlinear elliptic partial differential equations of coupled electro-thermal problems. In this paper we discuss the fundamental equations for the transport of electricity and heat, in terms of macroscopic variables such as temperature and electric potential. A fully coupled nonlinear weak formulation for electro-thermal problems is developed based on continuum mechanics equations expressed in terms of energetically conjugated pair of fluxes and fields gradients. The weak form can thus be formulated as a Discontinuous Galerkin method. The existence and uniqueness of the weak form solution are proved. The numerical properties of the nonlinear elliptic problems i.e., consistency and stability, are demonstrated under specific conditions, i.e. use of high enough stabilization parameter and at least quadratic polynomial approximations. Moreover the prior error estimates in the H1-norm and in the L2-norm are shown to be optimal in the mesh size with the polynomial approximation degree. [less ▲]
