[more ▼] L'article envisage de façon conjointe la correspondance de Francesco Guicciardini et les journaux de Marino Sanudo pour la période qui précède immédiatement le sac de Rome de mai 1527, moment critique où se noue un nouvel équilibre entre les forces en présence en Italie. Issus de patries ennemies que la Ligue de Cognac a assemblées autour d’un objectif commun - la défense des intérêts italiens mis à mal - la mise en perspective de leurs écrits offre un éclairage nouveau sur l’entreprise portée par Guicciardini et la perception immédiate de l’événement par les contemporains puisque cette prise rapide, qui suscita stupeur et étonnement, rendit pendant un certain temps les hommes du temps, dont Sanudo, incapables de trancher de la véracité des faits qui leur étaient rapportés. La confrontation de ces deux corpus à caractère «privé» permet en outre de mettre en évidence les disparités de jugement qui peuvent émerger, que l’on soit acteur ou spectateur de l’histoire.

[more ▼] Background. The role of cholecalciferol supplementation in end-stage renal disease (ESRD) patients has been questioned. The objective of this randomized double-blinded study is to assess whether cholecalciferol therapy can increase serum 25-hydroxyvitamin D [25(OH)D] levels in haemodialysed patients and the safety implications of this therapy on certain biological parameters and vascular calcifications score. Methods. Forty-three haemodialysis patients were randomized to receive placebo or cholecalciferol (25 000 IU) therapy every 2 weeks. The biological parameters, serum calcium, phosphorus, 25(OH)D and parathormone (PTH) levels, were monitored monthly for 12 consecutive months. Vascular calcifications were assessed by lateral X-ray radiography. Results. At baseline, the mean serum 25(OH)D levels were low and similar in both groups. Thirty patients (16 treated and 14 placebo) completed the study: 11 patients died (5 placebo and 6 treated), 1 patient dropped out and 1 patient was transplanted (both from the placebo group). After 1 year, the percentage of 25(OH)D deficient patients was significantly lower in the treated group. None of the patients developed hypercalcaemia. The PTH levels tended to increase over the study period under placebo and to decrease in the cholecalciferol group. The median changes in PTH levels from baseline to 1 year were statistically different between the two groups [+80 (−58 to 153) and −115 (−192 to 81) under placebo and cholecalciferol treatment, respectively, P = 0.02].The calcification scores increased equivalently in both groups (+2.3 per year). Conclusions. Cholecalciferol is effective and safe, and does not negatively affect calcium, phosphorus, PTH levels and vascular calcifications. Additional studies are needed to compare the impacts of nutritional and active vitamin D agents on vascular calcification and mortality. [less ▲] Detailed reference viewed: 20 (4 ULg) Blattmasken.

[more ▼] Fixité et mouvement coexistent fréquemment dans l’imagerie antique. Les Blattmasken en sont la parfaite illustration, car ils se caractérisent à la fois par une frontalité presque exemplaire et par un dynamisme végétal insufflé par les feuilles dont ils sont composés. Les quatre exemples choisis pour illustrer ce propos correspondent chacun à une formule particulière d’intégration des têtes végétalisées dans leur environnement immédiat. Celles-ci peuvent en effet être isolées de tout contexte végétal, intégrées dans un décor de rinceaux, ou encore structurellement liées à celui-ci en lui donnant naissance ou en émergeant de l’une de ses volutes. Cette forme de végétalisation de la figure humaine semble se rattacher à une hybridation plutôt qu’à une métamorphose. Cette fusion des règnes humain et végétal révèle une symbolique complexe qu’il conviendra de préciser. [less ▲] Detailed reference viewed: 13 (0 ULg) Des Blattmasken dans la Rome carolingienne.

[more ▼] La Blattmaske ou tête végétalisée est un motif romain apparu au Ier siècle apr. J.-C. Elle ne cessa d’être utilisée dans l’univers des formes , et donc de se renouveler. Mais il est un milieu qui constitue un jalon important dans l’histoire de son utilisation : la Rome de l’époque carolingienne. Après une rupture de près de quatre siècles dans la mise en oeuvre italique du motif, le remploi de fragments du temple de Sol Invictus semble en effet être à l’origine d’un certain regain d’intérêt pour le sujet dans des églises romaines du IXe siècle. Bien qu’il ne soit pas toujours aisé de distinguer des originaux antiques spoliés, parfois retravaillés, de créations médiévales, l’examen des fragments et de leur contexte permet de préciser leur origine et leur signification.

[more ▼] Depuis les travaux de Jean-Louis FOURNEL et Jean-Claude ZANCARINI, notamment, il est établi que les auteurs florentins qui vécurent à l’époque des guerres d’Italie identifièrent immédiatement la nouveauté et le caractère extraordinaire des faits qui bouleversèrent leur époque. Parmi ceux-ci, le célèbre Nicolas Machiavel mais aussi son ami et contemporain, Francesco Guicciardini, qui, si l’histoire littéraire ne lui a pas toujours fait la part belle, retrouve ces dernières années la place qui lui revient dans celle des idées. Auteur, historiographe mais aussi lieutenant des troupes pontificales lors de la Ligue de Cognac et, donc, acteur de l’histoire en train de se jouer, Francesco Guicciardini est en prise directe avec les événements ; dans sa volumineuse correspondance se mêlent petite et grande Histoire. Or, si le substantif et l’adjectif « contemporaneo » existent en italien depuis Dante au moins, Guicciardini n’en fait l’usage ni dans ses œuvres, ni dans ses lettres qui ne comptent aucune occurrence du terme. Partant de ce constat, je me propose, dans mon article, de relever et d’analyser le langage utilisé par Guicciardini pour nommer le moment auquel il vit, en cerner les contours et la façon dont celui-ci se distingue de ce qui précède pour former un moment à part : les expressions qui disent le présent (tempo presente/tempi presenti, questi tempi, medesimi tempi) et celles qui le caractérisent (conditione de' tempi, extraordinario, tempi strani) ou qui expriment le moyen de l’affronter (remedii conformi a’ tempi) seront, dès lors, au centre de mon attention.

[more ▼] Blattmasken belong to vegetalized human figures used in parietal decoration of nymphaei and domestic ponds. Their use depends on the process of iconographic forms’ transmission already highlighted between the parietal mosaic, the italic mural painting of Ist century a.C. and the African ground mosaic. This transfer is discussed in the light of two cases : the House of Neptune and Amphitrite at Herculanum and the House of the Nymphs at Neapolis. The study is based on their iconographical environments and on their typology. It highlights two different symbolic conceptions of the motive.

[more ▼] This paper deals with a two-part system integrity protection scheme to be installed in distribution networks, to counteract fault-induced delayed voltage recovery or even short-term voltage instability due to induction motors. The first part consists of a fast triggered but temporary reduction of some loads to facilitate motor re-acceleration after fault clearing. The second part resorts to load shedding, as a back-up. The scheme relies on purely distributed controllers; each of them measures a bus voltage and interrupts/disconnects load at the same bus. Tests have been performed on a generic MV/LV system. They illustrate the benefit of load interruption and the selectivity of the proposed scheme.

[more ▼] The lack of consideration for Ecosystem Services (ES) values in current decision-making is recognised as one of the main reasons leading to an intense competition and arguably unsustainable use of well-located available land. In this paper, we present a framework for the Valuation Of Terrestrial Ecosystem Services (VOTES), aiming at structuring a methodology that is applicable for valuing ES in a given area through a set of indicators that are both meaningful for local actors and scientifically constructed. Examples from a case study area in central Belgium are used to illustrate the methodology: a stepwise procedure starting with the valuation of ES at present. The valuation of the social, biophysical and economic dimensions of ES are based on current land-use patterns. Subsequently, scenarios of land-use change are used to explore potential losses (and/or gains) of ES in the future of the study area. With the VOTES framework, we aim at [1] incorporating stakeholders inputs to widen the valuation process and increase trust in policy-oriented approach; [2] integrating valuation of ES with a sustainable development stance accounting for land-use change; and [3] developing suggestions to policy-makers for integrating ES monitoring in policy developments.

[more ▼] Vitamin D (VTD) treatment is recommended in patients presenting different causes of diseases. To treat these patients, physicians rely on the different available pharmaceutical forms present in their country. Unfortunately, even in a given country, there is no consensus on the best way to treat the patients. In Belgium, VTD is mostly prescribed as ampoules containing 25,000 IU of VTD. In this randomised controlled study, we evaluated whether four therapeutic schemes using multiples of 25,000 IU of VTD according to basal vitamin D concentration were able to increase or maintain the 25(OH)D serum level above 30 ng/mL. We randomized 175 subjects who received the drug () or placebo (). Total duration of the study was 12 weeks. Doses ranged from 4167 to 1667 IU/day. Blood sampling was performed at baseline and each 4 visits. In the treated (placebo) subjects, mean 25(OH)D serum concentration was 18.7 (19.1) ng/mL at baseline and 31.5 (20.7) ng/mL at w-12. At the end of the study, 57.1% of the subjects treated with VTD presented 25(OH)D serum concentration ≥30 ng/mL, whereas 94.3% were ≥20 ng/mL. In conclusion, the doses administered were safe and increased or maintained the 25(OH)D concentration ≥20 ng/mL. However, concentrations ≥30 ng/mL were only achieved in 57.1% of the subjects.

[more ▼] 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.

[more ▼] Nowadays, microorganisms are more and more often used as biocontrol agents for crop protection against diseases. Among them, bacteria of Bacillus and Paenibacillus genders are already used as commercial biocontrol agents. Their mode of action is supposed to be related to their production of antibiotics, such as cyclic lipopeptides, which exhibit great antimicrobial activities. We chose to work with a Paenibacillus polymyxa strain (Pp56) very resistant to various microorganisms. The bacteria were grown simultaneously with Fusarium oxysporum and we applied matrix-assisted laser desorption/ionization-Fourier transform ion cyclotron resonance (MALDI-FTICR) mass spectrometry to identify the antibiotics compounds present in the fungus growth inhibition area. We, therefore, identified fusaricidins A, B, and C and numerous members of the LI-F antibiotics family. MALDIFTICR mass spectrometry imaging was then used to follow the diffusion of lipopeptides involved in the inhibitory activity over time. We analyzed the molecular content of the inhibitory area at different Pp56 and Fusarium incubation durations and concluded that some lipopeptides such as fusaricidin B and a mixture of LI-F05b/06b/08a were mainly involved in the defense mechanism of Pp56. Our study confirms that MALDI imaging may be a powerful tool to quickly determine which molecular species is involved in an antagonism with another microorganism, avoiding time-consuming steps of extraction, purification, and activity tests, which are still commonly used in microbiology.

[more ▼] The French Society of Clinical Biochemistry conducted this study to compare the accuracy and performances of the best creatinine enzymatic assays and the compensated Jaffe methods from the same manufacturers. Creatinine was measured in 3 serum pools with creatinine levels of 35.9 ± 0.9 μmol/L, 74.4 ± 1.4 μmol/L, and 97.9 ± 1.7 μmol/L (IDMS determination). The performances of the assays (total error that includes the contribution of bias and imprecision) were evaluated using Monte-Carlo simulations and compared against desirable NKDEP criteria. The enzymatic assays always fell within the desirable total Error of 7.6%. By contrast, this requirement was never obtained for the compensated Jaffe methods at the critical level of 74.4 ± 1.4 μmol/L. Only the compensated Jaffe creatinine on Olympus analyzer reached this specification at 35.9 ± 0.9 and 97.9 ± 1.7 μmol/L levels. This study demonstrates that, despite substantial improvement regarding traceability to the IDMS reference method and precision, compensated Jaffe creatinine methods, by contrast to enzymatic ones, do not reach the desirable specifications of NKDEP at normal levels of creatinine.

[more ▼] Recent technology reviews have identified the need for objective assessments of aircraft engine health management (EHM) technologies. To help address this issue, a publicly available gas path diagnostic benchmarking problem has been created and made publicly available. This software tool, referred to as the Propulsion Diagnostic Method Evaluation Strategy (ProDiMES), has been constructed based on feedback provided by individuals within the aircraft EHM community. It provides a standard benchmarking problem enabling users to develop, evaluate and compare diagnostic methods. This paper will present an overview of ProDiMES along with a description of four gas path diagnostic methods developed and applied to the problem. These methods, which include analytical and empirical diagnostic techniques, will be described and associated blind test case metric results will be presented and compared. Lessons learned along with recommendations for improving the public benchmarking processes will also be presented and discussed.

[more ▼] Au cœur de l'espace de la cour, le confesseur du Prince présente un profil singulier. La relation qu'il entretient avec son pénitent est unique : tenu à l'obéissance envers le souverain ou son représentant pour les aspects temporels, ce religieux a la faculté unique d'examiner, de conseiller et de juger la spiritualité du premier personnage de l'État. Attaché à la personne du Prince, les relations de cet ecclésiastique avec les autres courtisans ne peuvent être appréhendées au moyen d'une grille de lecture hiérarchisant les rapports sociaux : échappant à l'organisation laïque – mais pas protocolaire – de la cour et ne dépendant pas directement de la Chapelle royale, le confesseur bénéficie d'une autonomie relative. En outre, son pouvoir politique, en partie officiel grâce aux dignités et charges dont ce religieux est pourvu, est avant tout perçu comme une magistrature d'influence à la portée difficilement mesurable. Enfin, les obligations matérielles liées à l'appartenance de ce prélat à un ordre religieux achèvent de distinguer cet ecclésiastique des autres serviteurs princiers. Cette communication visera à distinguer les particularités de la charge de confesseur princier au sein de la société de cour. L'étude portera particulièrement sur la cour de Bruxelles durant la première moitié du xviie siècle.
