1) Visible region. When carried on board of space vehicles telescopes can be used with their maximum theoretical resolving power, by avoiding the effects of atmosphere turbulence. As the atmospheric scattering is suppressed, observations of very low contrast phenomena are made easier. Closer observations of the solar system objects are made possible. 2) Infra red region. Observations taken from 30 km high are freed of most of the atmospheric absorption. But some infra red observations require the use of satellites (for example scanning of the whole sky within spectral regions). Needed observations are reviewed. [less ▲]

This article proposes a new analytical framework for the study of political careers in multi-level systems. It is argued that the study of vertical movements between political arenas, which constitutes the prevalent methodological approach in the literature on political careers, should be complemented by the study of horizontal movements within political arenas. Based on a longitudinal analysis of individual political careers, the micro-approach developed in this article allows the comprehension of all territorial dynamics of political careers in multi-level systems. Based on an in-depth case study of all 419 Walloon careers in Belgium, four career patterns are identified: national careers, regional careers, multi-level careers and discrete careers. Although Belgium presents an integrated structure of opportunity, it is demonstrated that key evidences underline the prevalence of a regional and a national political class along a highly integrated political elites.

The establishment of regional Parliaments in Western Europe has renewed the study of political careers. Since the beginning of the 21st century, an increasing number of – conceptual and empirical – studies have been published on political careers in multi-level systems. Despite the richness of the novel analytical approaches proposed, I argue that the current trend in the literature that consists to label a whole region (or even a country) as illustrations of integrated, alternative, or hierarchical careers pattern (might) produce an imperfect picture of the reality – or even worse, could lead to a misleading conclusion. I rather hypothesize that, within a single region, the possibility of multiple careers patterns has to be a priori considered: distinct professional political classes might co-exist. In this respect, two methodological elements must be integrated into the research design. Firstly, from a heuristic point of view, researchers should move from the (mere) analysis of level-hopping movements between two elections and rather adopt a microscopic point of view through the study of every single individual political careers (internal validity). Secondly, the cases under investigation should be selected only if they display a critical amount of legislatures in order to observe robust and non-contingent career patterns (external validity). For the sake of parsimony and clarity of my demonstration, I recourse to an in-depth case study – Walloon political careers – but cross-sectional research are certainly determinant to (in-)valid this hypothesis.

In Belgium, a number of girder bridge deck slabs have over the past several years been displaying major degradations (delamination, disaggregation, etc.) capable, in time, of leading to slab perforation. This form of degradation, called "rotting of bridge deck slab concrete" is not uniformly distributed over the deck surface: deteriorated zones can be distinguished from intact zones and moreover are often associated with the presence of dark spots. On the lower surface of some such spots, the previously-carbonated concrete layer can sometimes once again display a pH of above 8.3. It will also be demonstrated that this anomaly may be attributed to a migration of alkaline through the concrete slab towards the lower surface, thereby causing a re-alkalinization of the carbonated layer and hence a rise in pH.

The manifestly artificial nature of film animation, the constant reinvention of the apparatus and its claims to alterity, all shape its own particular (and problematic) identity; most of all, however, these elements of animation interrogate cinema itself on historical and aesthetic levels. The study that reflects upon certain emblematic films demonstrates how the enterprise of film animation invites cinema to take stock of itself, to look back upon its history and to consider the possibilities of new developments in perspective and previously unexplored mobile arrangements in its time and space.

Three years after its start up, the building considered here is not yet providing a satisfactory comfort to its occupants. Too cold and too hot environmental conditions were too often encountered in different occupied zones, mainly in mid-season and in summertime. The execution of a re- commissioning process would support in resolving these problems. Previous verifications allowed us to confirm that almost all HVAC components considered are technically “correct” and that almost all problems are coming from mistakes committed when installing and tuning these components. The re-commissioning presented in this paper is based on both calculation and experimental data. [less ▲]

Commissioning is a unique opportunity, for all partners concerned, to learn a lot about the real behavior of a HVAC system. It has to start from comfort and health requirements in occupancy zones, and going back to the plant through the whole air conditioning system. Focus is given here to the so-called “re-commissioning” and the proposed principles are illustrated by reference to a specific case study: the “CAMET” building. The "CA-MET" is a new ministry office building, designed for an occupancy of about 1000 people and located in the city of Namur, in Belgium. The building is cooled, thanks to a VAV/CAV system. Heating is provided independently by a classical hydronic radiator system. By lack of time, here as usually, the HVAC initial commissioning was done in a hurry… And, as soon as starting his job, the manager received a fair amount of complaints from the building occupants. The building was selected as a "good" case study to illustrate the work developed in the frame of the IEA-ECBCS "annex 40" project… This paper is presenting the methodology used in the first re-commissioning phase, some examples of results and also some general recommendations.

In multinational federations, identities are a chief variable of the political life. By definition, the ethno-linguistic identities play(ed) an important role in the federal dynamics of the country. In most cases, the institutional design is in fact adapted or has been adapted to the ethno-linguistic divisions of the country. According to quite a few scholars, it is especially true for political elites who are not only shaped by this variable but also use this variable to legitimate their attitudes and actions. Therefore political elites of each ethno-linguistic group appeared to behave as monolithic blocks, standing against each other along ethno-linguistic lines. Nonetheless, this view neglects the role of party interests in explaining the behaviors of political elites. An important question for multinational federations can be raised: do identities matter more that party interests? The current reform of the Belgian state provides a fertile ground to test this hypothesis. To what extent, party interests can account for political elites’ position in the debate about the 6th Belgian constitutional reform? To explore these questions, we surveyed every representative of Belgium’s seven legislative assemblies with a standardized questionnaire (Summer 2011). This research will help us apprehend the rationale behind political elites’ attitudes – be it identities, party interests or a mix of them – negotiating the new boundaries of the state. [less ▲]

At room temperature, the local structure of crystalline group V elements (As, Sb,middotmiddotmiddot) and their IV-VI isoelectronic compounds (GeSe,middotmiddotmiddot) is governed by a Peierls distortion of the simple cubic or NaCl structure which is a symmetry breaking electronic instability. The morphology of the distortion is determined by the filling ratio of the p-band; for a half-filled p-band, the sixfold coordination becomes 3 (short, covalent) +3 (long, van der Waals). In general, at high temperature, the structure recovers its higher coordination number. Neutron diffraction experiments have been made in the liquid state at lambda=0.7 Aring. It is observed that the Peierls distortion is still present in the liquid for most IV-VI compounds. This behavior is observed and discussed for a series of Sn and Ge chalcogenides: SnS, SnSe, GeS, GeSe and GeTe and their temperature evolution is discussed. GeSe and GeTe show an interesting re-entrant phase behavior. The heaviest IV-VI compound SnTe does not show a distorted state. We demonstrate that the hardness of the repulsive potential is a key parameter in this mechanism [less ▲]

Recent electron microscopic immunolocalization studies (Scheer and Rose, 1984) indicated that RNA polymerase I is located in, and probably confined to, the fibrillar centres of the nucleoli. This conclusion appears to be in contradiction to previous autoradiographic studies reporting that transcription of rRNA genes takes place in the dense fibrillar component. Despite the fact that rRNA transcription occurs in the dense fibrillar component of Ehrlich tumour cell nucleoli, we show in the present paper that dense fibrillar component containing rapidly labelled RNA can be visualized not only around but also inside the fibrillar centres.
