In this paper I discuss the dossier of cults for Arsinoe II Philadelphos to investigate how the worship of a sovereign could concretely become a constitutive part of the religious life of the communities composing a kingdom. I argue that in order to let the worship of a sovereign survive the political context in which it was first conceived, a certain degree of freedom and of individual initiative must have been encouraged among potential worshippers, so that the cults could become part of a durable shared religious and political identity connecting the individual with the collective sphere.

Our paper reconsiders the religious and social significance of a corpus of statuettes representing crouching children with jewels and amulets, principally dedicated in shrines on Cyprus from about the mid–fifth century BC down to the Hellenistic period. The most plausible interpretation of these statues, that of votive dedications aiming to evoke divine protection on small children, will be substantiated by discussion of discovery contexts and of the significance of amulets and other objects decorating these statues, as well as by broader considerations on the place of small children in temples. The variety of configurations of these statues will also be taken into account in order to discuss the possibility of various interpretations instead of one single interpretative paradigm. [less ▲]

The calcium-sensing receptor (CaSR) has been implicated in the ischemia/ reperfusion (I/R) cascade in heart, liver and brain. Renal I/R occurs at the time of transplantation (Tx), with a deleterious impact on early graft function. Here, we retrospectively investigated if the use of cinacalcet, a CaSR agonist, in kidney transplant recipients (KTR) influences early graft recovery. All KTR from 2007 to 2012 in our Academic Hospital were prospectively included in a database. Patients actively treated with cinacalcet on the day of Tx were retrospectively identified from this database and matched with controls on (i) type of donor (living [LD], deceased after brain or circulatory death [DCD]); (ii) cold ischemic time (CIT) ` 1 h; (iii) residual diuresis (` 500 ml); and (iv) donor age (` 5 years). Delayed graft function (DGF) was defined as dialysis requirement after Tx. Baseline characteristics were compared between groups with student’s t-test or Chi-2 as appropriate. The endpoint was the percentage of DGF in both groups. Among 337 KTR, 36 (10.7%) were treated with cinacalcet at Tx. Control group included 61 patients. Characteristics of patients and donors are summarized in the table. DGF occurred in 42 and 23% of cinacalcet-treated and control groups, respectively (p = 0.05). These retro- spective observations suggest that CaSR activation at the time of Tx impairs early graft recovery. [less ▲]

This paper proposes a study of the accuracy of a guitar amplifier loudspeaker simulation. The simulation is based on a non-linear convolution of a signal using Volterra kernels, which are measured in anechoic conditions with a sine-sweep technique. In this paper, we propose an evaluation of the method to minimise the cost in CPU load, while keeping the best performance in the sound reproduction. To assess the performance of the method, we measure errors between the simulated and real sounds. Human listening tests are moreover proposed in order to determine the minimum level of accuracy leading to unaudible differences with the real loudspeaker.. [less ▲]

Objectives Clearly associated to neonatal meningitis, Group B streptococci (GBS) classified as sequence type-17 (ST-17) are defined as the “highly virulent” clone amongst GBS. The aim of this study was to evaluate an easy and rapid method, recently described to detect ST-17 and ST-1 GBS, based on distinguishing peak-shifts present on the protein spectrum of these 2 sequence types, using a Microflex (Bruker) matrix-assisted laser desorption/ionization time of flight mass spectrometer (MALDI-TOF MS). Methods This study was performed on 67 multi locus sequence typed (MLST) GBS originated from the Belgian and Czech National Reference Centers, including 18 ST-17 and 16 ST-1. After culture on blood agar, an ethanol/formic acid extraction was performed on each strain. Each extract was spotted once on a target plate, overlaid with 1 µl alpha-cyano-4-hydroxycinnamic acid matrix and further analysed by a Microflex MALDI-TOF MS. One spectrum per isolate was recorded, 240 laser shots being recorded for each spectrum. The spectra were further analysed using a Bruker prototype software, and 2 logarithmic values, one for ST-17 and one for ST-1, calculated from the intensities of the present and absent peaks, were obtained for each strain. If >0, this value indicated the presence of the specific sequence type. In a second step, the test was repeated on each strain with discordant result when compared with MLST. Results Compared with MLST method, the first analysis of the strains gave poor results, leading to very low sensitivities (77.8% for ST-17 and 50% for ST-1) but rather good specificities (85.7% for ST-17 and 98.0% for ST-1). After repeating the analysis on the strains with discordant result, sensitivity, 100% and 93.8%, and specificity, 87.8% and 98.0%, for ST-17 and ST-1 respectively were highly improved. Conclusion Since ST-17 and ST-1 GBS both show distinguishing peak-shifts on their protein spectrum, as described by Lartigue et al., the distinction of these 2 sequence types is now possible by MALDI-TOF MS. To our knowledge, this study is the first describing this application on a Microflex MS using a software to classify the strains. The observed results are promising but, given to the variability of the logarithmic value given by the software, the need to perform several measures on a same strain seems to be essential. After optimization of the analysis procedure, this rapid, easy and cheap method could be used to precociously detect ST-17 among GBS isolated from prenatal screenings, allowing a better follow up of the colonized mothers and a closer monitoring of their newborns. We would like to thank the Bruker Company which allowed us to evaluate the prototype software they have developed. [less ▲]

En raison de leur caractère violent et/ou de leur illégalité, certaines luttes ouvrières font l’objet d’un traitement médiatique et politique stéréotypé les maintenant à un niveau que l’on pourrait qualifier d’infrapolitique (« colère », « coup de sang », etc.). Un terme qualifie, très précisément, jusqu'à l'inflation rhétorique ces actions : « radicalité ». Ce dossier analyse les usages de la notion par divers acteurs (journalistes, juristes, politiques…), les liens entre radicalisation des registres d’action et luttes sociales, ainsi que les déterminants politiques, idéologiques et socio-culturels des discours fixant la frontière entre ce qui, dans une société donnée, relève de l'acceptable et de l'inacceptable.

Some soil Bacilli living in association with plant roots can protect their host from infection by pathogenic microbes and are therefore being developed as biological agents to control plant diseases. The plant protective activity of these bacteria has been correlated with the potential to secrete a wide array of antibiotic compounds upon growth as planktonic cells in isolated cultures under laboratory conditions. However, in situ expression of these antibiotics in the rhizosphere where bacterial cells naturally colonize root tissues is still poorly understood. In this work, we used Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry Imaging (MALDI MSI) to examine spatio-temporal changes in the secreted antibiome of B. amyloliquefaciens developing as biofilms on roots. Non-ribosomal lipopeptides such as the plant immunity elicitor surfactin or the highly fungitoxic iturins and fengycins were readily produced albeit in different time-frames and quantities in the surrounding medium. Interestingly, MS/MS experiments performed directly from the gelified culture medium, also allowed to identify a new variant of surfactins released at later time points. However, no other bioactive compounds such as polyketides were detected at any time, strongly suggesting that the antibiome expressed in planta by B. amyloliquefaciens does not reflect the vast genetic arsenal devoted to the formation of such compounds. This first dynamic study reveals the power of MALDI MSI as tool to identify and map antibiotics synthesized by root-associated bacteria and more generally, to investigate plant-microbe interactions at the molecular level.

X-ray microtomography, through quantification of soil structure at the microscale, could greatly facilitate the current understanding of soil hydrodynamic behaviour. However, binarisation method and processing choices are subjective and can have a strong impact on results and conclusions. In this study, we test a new method based on the porosity detectable by X-ray microtomography, while validation is achieved through comparison of soil microtomogram information with soil physical measurements. These measurements consist of water retention and unsaturated hydraulic conductivity using two different soil populations with only structural differences. To assess the porosity-based method performances, we compare it to four other methods, namely the global method of Otsu and three recent soil-dedicated local methods. The robustness of the porosity-based method is also tested in regard to different pre-processing procedures. In this paper we demonstrate that soil segmentation through a porosity-based method is an interesting issue. Indeed, it is less demanding in terms of time and computational requirements than its alternatives, and combines robustness and performances broadly comparable with the recent local methods.

Ce terme d’origine grecque désigne dans son acception générale l’imitation de la nature et, par extension, les modes et les moyens de l’imitation dans les arts. Dans son acception spécifique, il concerne l’ensemble des ressources poétiques et esthétiques employées à la représentation du réel en littérature. À l’époque contemporaine, la notion est utilisée dans les études littéraires soit pour qualifier globalement la vraisemblance de la fiction, principalement dans ses modalités romanesque et réaliste, soit pour désigner les interférences entre les procédés formels de l’œuvre (narration, description, dialogue) et les capacités plus ou moins mimétiques dont dispose cette dernière pour signifier le réel.

Cette communication porte sur la traduction, en Belgique, d’une politique européenne de l’emploi – la flexicurité – par différents acteurs institutionnels. À partir d’une analyse documentaire et d’une vingtaine d’entretiens semi-directifs, nous étudierons la manière dont ces acteurs s’approprient et interprètent la flexicurité. Nous nous appuierons principalement sur les apports récents de la sociologie de l’action publique, en particulier l’approche cognitive des politiques publiques (Surel, 2000 ; Muller et Surel, 1998) et l’européanisation des politiques d’emploi (Palier et Surel, 2007 ; 2010). Nous montrerons que cette appropriation a donné lieu, en Belgique, à une transformation de sens conféré à la sécurité, celle-ci étant dorénavant substitué à celui de la flexibilité. [less ▲]

In this paper, different formulations of Maxwell equations are combined for computing the shielding effectiveness of enclosures made from heterogeneous periodic materials. The validity of the homogenized parameters given by Maxwell-Garnett rules in the frequency domain are tested in the time domain using a nodal discontinuous Galerkin method, which uses an interface condition based on analytical solution in the frequency domain to replace a conductive sheet. This interface condition allows to avoid meshing the thin sheet, thus reducing the computational cost. Results of scattering by composite enclosures are presented in the frequency domain thanks to a Fast Fourier Transform. [less ▲]
