Les recherches archéologiques conduites au sud-est du forum de la ville romaine de Baelo claudia ont permis de mettre au jour au-dessus du secteur monumental, plusieurs phases de transformation, d’abandon et de réoccupation entre les IIIe et VIe s. Les structures découvertes ainsi que le nombreux mobilier qui leur était associé (monnaies, céramique, verre, métal, faune, etc.) fournissent un éclairage nouveau sur l’histoire et la nature de l’agglomération dans l’antiquité tardive, qui entre la fin du IVe s. et son abandon définitif au VIe s. ressemble moins à une ville qu’à un gros village.

En 2006, l’écrivain et essayiste allemand Hans Magnus Enzensberger publie Le perdant radical, un « essai sur les hommes de la terreur », conformément au sous-titre de cet ouvrage d’une soixantaine de pages dans lequel l’auteur décrit les multiples facettes d’un ensemble de figures meurtrières. Du tireur fou dans un lycée américain au combattant islamiste ceinturé d’explosifs, isolé ou organisé en groupe, tout perdant radical répond au même mécanisme : c’est « lorsqu’il aura repris à son compte le jugement des autres, ceux qu’il tient pour les gagnants (…) qu’il pète les plombs. » L’indistinction est frappante : pour Enzensberger, le perdant radical peut sévir seul ou en groupe ; son moteur profond, irréductible à un engagement politique ou religieux, reste le même dans les deux cas. Car pour l’essayiste, rien, pas même une théorie critique de la société, ne permet de rendre compte de la nature du perdant radical, si ce n’est la suppression de l’instinct de conservation. Dans plusieurs textes littéraires – on songe notamment à son poème Zur Frage der Bedürfnisse (1991) et à son entretien autobiographique fictif avec lui-même Erinnerungen an einen Tumult (2014) –, Hans Magnus Enzensberger crée ou recrée des figures de terroristes qui réalisent parfaitement le profil type du perdant radical. Andreas Baader, les jeunes bourgeois d’une secte marxiste en Suède, un terroriste islamiste en fuite, un guérillero sud-américain qui a perdu tout sens de la réalité, autant de figures fictionnelles ou refictionnalisées qui, partant d’une même position d’échec apparemment imposée de l’extérieur et assumée en tant que telle, superposent destruction et autodestruction. L’hypothèse générale à laquelle nous voudrions soumettre ces personnages de terroristes est qu’ils sont les héritiers d’une figure essentielle pour la littérature allemande et anglo-saxonne : l’amok.

Tillage is a common agricultural practice affecting soil structure and biogeochemistry. Pore network geometries are crucial to oxygen concentration, gas diffusivity, water location and water movement. Soil aggregates, 4–6 mm in diameter and collected from silty loam in Belgium and sandy loam in China, were scanned using a micro-computed tomography scanner. Images with a pixel size of 6.9 μm were then processed with ImageJ software for pore network analysis. The treatments were no tillage (C-NT) and conventional tillage (C-CT) in China, and shallow tillage (G-ST) and conventional tillage (G-CT) in Belgium. The results showed that aggregates in conservational tillage (G-ST and C-NT) had numerous connected pores compared with conventional tillage (G-CT and C-CT). The Euler number (Ev) was significantly lower and visible total porosity and surface area (SA) were significantly higher in conservational tillage (G-ST and C-NT) than in conventional tillage (G-CT and C-CT) in both studied locations. The predominant size of pores was significantly higher in conservational tillage (G-ST and C-NT) than in conventional tillage (G-CT and C-CT) (> 150 μm vs 90–120 μm). Pore location within the aggregates also showed differences, with porosity being evenly distributed in the aggregates under conventional tillage (G-CT and C-CT). Under conservational tillage (G-ST and C-NT), the aggregates were heterogeneous, showing higher porosity at the center of the aggregates. There was a higher soil organic carbon (SOC) content in the external layer than in the internal layer in conservational tillage in Belgium (G-ST). In no tillage in China (C-NT), the SOC in the external and internal layers, however, showed similar results. Overall, conventional tillage (G-CT and C-CT) reduced the proportion of the largest pores within soil aggregates, whereas there was no significant relationship between pore morphologies and SOC content. Further investigation is required to measure the active and slow carbon pool distribution in the different layers and under different tillage practices. [less ▲]

In the last years, supercritical fluid chromatography has largely been acknowledged as a singular and performing technique in the field of separation sciences. Recent studies highlighted the interest of SFC for the quality control of pharmaceuticals, especially in the case of the determination of the active pharmaceutical ingredient (API).Nevertheless, quality control requires also the determination of impurities. The objectives of the present work were to i) demonstrate the interest of SFC as a reference technique for the determination of impurities in salbutamol sulfate API and ii) to propose an alternative to a reference HPLC method from the European Pharmacopeia (EP) involving ionpairing reagent. Firstly, a screening was carried out to select the most adequate and selective stationary phase. Secondly, in the context of robust optimization strategy, the method was developed using design space methodology. The separation of salbutamol sulfate and related impurities was achieved in 7 minutes, which is seven times faster than the LC-UV method proposed by European Pharmacopeia (total run time of 50 minutes). Finally, full validation using accuracy profile approach was successfully achieved for the determination of impurities B, D, F and G in salbutamol sulfate raw material. The validated dosing range covered 50 to 150 % of the targeted concentration (corresponding to 0.3 % concentration level), LODs close to 0.5 μg/mL were estimated. The SFC method proposed in this study could be presented as a suitable fast alternative to EP LC method for the quantitative determination of salbutamol impurities. [less ▲]

This paper addresses the problem of an aggregator controlling residential heat pumps to offer a direct control flexibility service. The service consists of a power modulation, upward or downward, that is activated at a given time period over a fixed number of periods. The service modulation is relative to an optimized baseline that minimizes the energy costs. The load modulation is directly followed by a constrained rebound effect, consisting of a delay time with no deviations from the baseline consumption and a payback time to return to the baseline state. The potential amount of modulation and the constrained rebound effect are computed by solving mixed integer linear problems. Within these problems, the thermal behavior of the building is modeled by an equivalent thermal network made of resistances and lumped capacitances. Simulations are performed for different sets of buildings typical of the Belgian residential building stock and are presented in terms of achievable modulation amplitude, deviations from the baseline and associated costs. A cluster of one hundred ideal buildings, corresponding to retrofitted freestanding houses, is then chosen to investigate the influence of each parameter defined within the service. Results show that with a set of one hundred heat pumps, a load aggregator could expect to harvest mean modulation amplitudes of up to 138 kW for an upward modulation and up to 51 kW for a downward modulation. The obtained values strongly depend on the proposed flexibility service. For example, they can decrease down to 2.6 kW and 0.4 kW, respectively, if no rebound effect is allowed. [less ▲]

En 1975, la notion de conservation intégrée est consacrée par la Charte européenne du Patrimoine architectural, adoptée par le Comité des Ministres du Conseil de l’Europe avant d’être solennellement proclamée et développée au Congrès d’Amsterdam (21-25 octobre 1975). Renouvelant fondamentalement les pratiques de rénovation des centres anciens avec l’ambition de créer un dialogue entre aménageurs et conservateurs, cette approche résulte de dix années de réflexions nourries par des échanges entre experts principalement européens, initiés non seulement par le Conseil de l’Europe (Confrontations de Barcelone (1965), Bath (1966), La Haye (1967) et Avignon (1968)), mais également par l’ICOMOS, dès sa fondation en 1965 (Colloques de Cacérès (1965), Tunis (1966), Leningrad et Graz (1969), Lausanne (1973), Rothenburg et Bruges (1975)). Si un regard macroscopique révèle le rôle central joué par Piero Gazzola et Raymond Lemaire, respectivement président et secrétaire général de l’ICOMOS et auteurs, avec François Sorlin, d’une étude de synthèse préalable à la Charte européenne, cette contribution se propose d’augmenter la focale afin de révéler, à travers l’étude des actes des colloques, le rôle des réseaux d’acteurs en présence dans l’élaboration de la nouvelle politique.
