In the 1960s, the French changed direction – but neither did they adopt the more educative, journalistic Anglophone documentary tradition nor the Direct Cinema revision of it, although the turn also made much of synchronous sound. Instead, French documentary, against a background of considerable theoretical debate on the cinema in general, turned back to Vertov and Kino-Pravda. [less ▲]

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. [less ▲]

La présente communication a pour objectif d’étudier le rôle de la dynastie belge dans le développement scientifique en Belgique sous le règne d’Albert Ier. Sont ici concernés le Roi, mais aussi la reine Elisabeth et leurs enfants, au premier rang desquels figure le prince Léopold, ainsi que l’entourage du souverain, à savoir la Maison du Roi (Grand Maréchal, Liste civile, Cabinet, Maison militaire) et les personnalités proches (issues des milieux académiques, industriels et politiques notamment). La première partie de l’exposé concernera la personne du roi. Si la Constitution belge limite son action, celui-ci exerce une « magistrature d’influence » qui se marque par le colloque singulier, les relations ou le patronage, notamment en matière de science. Il s’agira ici de déconstruire et d’analyser les origines du mythe du « roi-savant ». L’étude portera ensuite sur la reconstitution des milieux, des cultures, des climats intellectuels dans l’entourage d’Albert et Elisabeth ; par corollaire les projets initiés ou soutenus à la cour. Plusieurs pistes de réflexion seront dès lors abordées: conception par les personnes précitées du rôle de la science dans la société ; influence de celles-ci dans le développement de la science (institutions, initiatives, projets) ; rapports entre la dynastie et les institutions scientifiques ; étude des relations entre la dynastie et le Congo dans le domaine de la science. L’objectif sera de voir dans quelle mesure les réseaux constitués ont pu constituer les prémisses d’une « politique scientifique ». Cette communication, basée en grande partie sur les archives conservées au Palais royal de Bruxelles, s’intègre dans le cadre, plus large, d’une thèse de doctorat entamée à l’Université de Liège en octobre 2011, laquelle est consacrée aux relations science-dynastie depuis Albert Ier jusqu’au début du règne de Baudouin et la « Commission nationale des sciences » de 1959.

In the framework of instrument calibration, straylight issues are a critical aspect that can deteriorate the optical performances of instrument. To cope with this, a new facility is designed dedicated for in-field and far field straylight characterization: up to 10-8 for in-field and up to 10-10 for far field straylight in the visible to NIR spectral ranges. Moreover, from previous straylight test performed at CSL, vacuum conditions are needed for reaching the 10-10 rejection requirement mainly to avoid air/dust diffusion. The major constrains are to design a straylight facility either for in-field and out-field straylight measurements. That requires high dynamic range at source level and a high radiance point source allowing small diverging collimated beam. Moreover, the straylight facility has to be implemented into a limited envelope and has to be built with vacuum compatible materials and black coating. As checking the facility performance requires an instrument better than the facility itself, that is no easy to find, so that the performances have been estimated through a modelisation into a non sequential optical software. This modelisation is based on CAD importation of mechanical design, on BRDF characteristics of black coating and on statistical averaging of ray tracing at instrument entrance. [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.

A supposer que le concept de valeur soit un concept empirique, qui a sa source dans l'expérience, de quel type est l'expérience de la valeur? Dans les pages suivantes, je suggère qu’Ehrenfels et Meinong ont apporté certaines améliorations substantielles à la position de Brentano. Ces améliorations résident essentiellement dans les deux points suivants : (1) les volitions se caractérisent par une dimension « active » ou conative qui fait défaut aux sentiments, ce qui interdit de les ranger dans une seule et même « classe » de phénomènes psychiques ; (2) le concept de valeur trouve son origine empirique dans les volitions ou les phénomènes conatifs, non dans les sentiments ou phénomènes affectifs.

This volume presents the complete collection of complete pots and profiles (ca. 1800 vessels) dating to the 3rd millennium BC, recovered during the excavations carried out at Tell Beydar during sixteen seasons (from 1992 to 2010). Tell Beydar, located in the syrian Jezirah region was a second rank urban center during the second part of the 3rd millennium BC. The EJZ 3b city has been widely explored by extensive excavations and offered large assemblages of archaeological material. This monograph offers a clear vision of the material culture of the site and allows us to insert it in the cultural landscape of Upper-Mesopotamia during the 3rd millennium BC. [less ▲]

The well-studied semigroup Sg(A) = {b : b = Ax; x in Z^n; x >= 0} can be stratified by the sizes of the polyhedral fibers IPA(b) = {x : Ax = b; x >= 0; x in Z^n}. The key theme of this paper is a structure theory that characterizes precisely the set Sg_k(A) of all vectors b in Sg(A) such that their fiber IPA(b) has at least k-solutions. We demonstrate that this set is finitely generated, a union of translated copies of a semigroup which can be computed explicitly via Hilbert bases computations. Related results can be derived for those right-hand-side vectors b for which IPA(b) has exactly k solutions or fewer than k solutions. We also show that, when n, k are fixed natural numbers, one can compute in polynomial time an encoding of Sg_k(A) as a generating function, using a short sum of rational functions. As a consequence, one can identify all right-hand-side vectors that have at least k solutions. Using this tool we prove that for fixed n; k the k-Frobenius number can be computed in polynomial time, generalizing a well-known result of R. Kannan. [less ▲]

The strength of respiratory muscles is crucial for quality of life, especially for patients with lung or neurological disorders. Several methods can be used to assess them: i.e direct or indirect, voluntary or involuntary. The conventional spirometry method assesses indirectly the respiratory function by measuring maximum inspiratory and expiratory pressure, which reflects the coordination of all respiratory muscles. Techniques of magnetic and electrical stimulation can detect a specific muscle dysfunction, independently of the patient's motivation, however they are invasive methods as measurements are made in the esophagus and stomach. The voluntary techniques are generally non-invasive and require patient's cooperation. Measures of respiratory muscle strength, coupled to a conventional spirometry, can predict the development of ventilatory support in patients at risk, and may be useful during weaning from mechanical ventilation in intensive care units.

Palaeoecological and archaeological studies have demonstrated that human populations have long inhabited the moist forests of central Africa. However, spatial and temporal patterns of human activities have hardly been investigated with satisfactory accuracy. In this study, we propose to characterize past human activities at local scale by using a systematic quantitative and qualitative methodology based on soil charcoal and charred botanical remains. A total of 88 equidistant test-pits were excavated along six transects in two contrasting forest types in southern Cameroon. Charred botanical remains were collected by water-sieving and sorted by type (wood charcoals, oil palm endocarps, and unidentified seeds). A total of 50 Accelerator Mass Spectrometry 14C dates were also obtained. Results showed that charred macroremains were found at multiple places in the forest, suggesting scattered human activities, which were distributed into two main periods (Phase A: 2300-1300 BP – Phase B: 580 BP to the present). Charred botanical remains indicated two types of land use: (i) domestic, with oil palm endocarps most often associated with potsherds (villages) and (ii) agricultural, with charcoal as probable remnant of slash-and-burn cultivation (fields). Oil palm endocarp abundance decreased with distance from the identified human settlements. Our methodology allowed documenting, at high resolution, the spatial and temporal patterns of human activities in central African moist forests and could be applied to other tropical contexts.
