[more ▼]Aims: The X-ray emission of massive stars has been studied when these objects are in their main-sequence phase, as well as in their Wolf-Rayet phase. However, the X-ray properties of the transitional Luminous Blue Variable (LBV) phase remain unknown. Methods: Using a dedicated but limited XMM survey as well as archival XMM and Chandra observations, we performed the first X-ray survey of LBVs: about half of the known LBVs or candidate LBVs are studied. Results: Apart from the well known X-ray sources eta Car and Cyg OB2 #12, four additional LBVs are detected in this survey, though some doubt remains on the association with the X-ray source for two of these. For the other LBVs, upper limits on the flux were derived, down to $\log[L_{\rm X}/L_{\rm BOL}]-9.4$ for PCyg. This variety in the strength of the X-ray emission is discussed, with particular emphasis on the potential influence of binarity.

[more ▼]Studies on nationalism were often interested with the city, especially the city centers. The politics of heritage, the architecture of public buildings and the design and use of central public spaces are often studied in relation to national identity politics. Municipal politics of the historical city in the face of central authorities’ urban politics is also frequently approached in the light of Nation-State building issues. If no doubt the consideration of city centers as a vantage point for understanding the relation between nationalism and the city is an interesting one that bore many fruits, we believe that a vantage point concentrating on the peripheries can highly contribute in unveiling other aspects of this relation. This paper aims at investigating the potentialities of this contribution. As the place where urbanization is taking place, the periphery is: - Where the national identity construction logic is put to test. First because, historically, it is here where the confrontation between the urban and the rural did first take place. Second, because rural exodus and migration, usually more important in the periphery, will continue to challenge it. - Where the city and the hinterland get connected through different national territory building networks. - Where the Nation-State central authorities will find the largest land reserves to develop their large emblematic projects. - Where urban fragmentation poses the strongest challenge to the unitarian message of nationalism, but also is where some nationalist movements might best develop In fact, the periphery represents equally a fertile ground for nationalism and for resistances to it. This paper will rely on the city of Beirut as a case study.

[more ▼]Single Point Incremental Forming (SPIF) is a recent sheet forming process which can give a symmetrical or asymmetrical shape by using a small tool. Without the need of dies, the SPIF is capable to deal with rapid prototyping and small batch productions at low cost. Extensive research from both experimental and numerical sides has been carried out in the last years. Recent developments in the finite element simulations for sheet metal forming have allowed new modeling techniques, such as the Solid Shell elements, which combine the main features of shell hypothesis with a solid-brick element. In this article, two recently developed elements -SSH3D element [1, 2] and RESS3 element [3]- implemented in Lagamine (finite element code developed by the ArGEnCo department of the University of Liège) are explained and evaluated using the SPIF line test. To avoid locking problems, the well-known Enhanced Assumed Strain (EAS) and Assumed Natural Strain (ANS) techniques are used. The influence of the different EAS and ANS parameters are analysed comparing the predicted tool forces and the shape of a transversal cut, at the end of the process. The results show a strong influence of the EAS in the forces prediction, proving that a correct choice is fundamental for an accurate simulation of the SPIF using Solid Shell elements.

[more ▼]Urban sprawl is a major issue for sustainable development. It represents a significant contribution to energy consumption of a territory especially due to transportation requirements. However, transport energy consumption is rarely taken into account when the sustainability of suburban structures is studied. In this context, the paper presents a method to estimate transport energy consumption in residential suburban areas. The study aimed, on this basis, at highlighting the most efficient strategies needed to promote awareness and to give practical hints on how to reduce transport energy consumption linked to urban sprawl in existing and future suburban neighborhoods. The method uses data collected by using empirical surveys and GIS. An application of this method is presented concerning the comparison of four suburban districts located in Belgium to demonstrate the advantages of the approach. The influence of several parameters, such as distance to work places and services, use of public transport and performance of the vehicles, are then discussed to allow a range of different development situations to be explored. The results of the case studies highlight that travelled distances, and thus a good mix between activities at the living area scale, are of primordial importance for the energy performance, whereas means of transport used is only of little impact. Improving the performance of the vehicles and favoring home-work give also significant energy savings. The method can be used when planning new areas or retrofitting existing ones, as well as promoting more sustainable life styles regarding transport habits.

Fossil fuels-fired ... [more ▼]One of the biggest upcoming challenges concerning both environmental and energy systems engineering is the control and limitation of greenhouse gas emissions due to human activity. Fossil fuels-fired power plants are in this context one of the main contributors due to the large amounts of CO2 emitted. Different technologies have been developed for capturing CO2 from such power plants. This work focuses on post-combustion CO2 capture by reactive absorption into amine solvents like monoethanolamine (MEA). The main drawback of this technology is actually the high energy requirement of the process, especially for solvent regeneration. It is then highly interesting to model the capture process so that optimal operating conditions could be approached by simulation thus reducing the number of expensive experimental tests. Thanks to the simulation, it has been possible to identify the most influent process variables and to optimize their value. It was also possible to study the impact of process modifications on the global capture efficiency. The improvements studied allowed for a reduction by up to 14% of the process exergy consumption. Another major drawback of the post-combustion CO2 capture is solvent degradation, which can be due to thermal as well as oxidative mechanisms. Degradation affects the CO2 capture process since it may cause corrosion, foaming and fouling, possibly inducing a decrease of the solvent efficiency and high additional operating costs due to solvent replacement. In order to study degradation of conventional amine solvents as well as degradation of novel solvents, a degradation test rig has been built at the University of Liège in collaboration with the company Laborelec, member of the GDF SUEZ group. First results show that degradation obtained on this lab installation can be compared to degradation results observed on CO2 capture pilot installation. The final objective of this thesis is to make a link between degradation and simulation. Experimental data obtained on the degradation test rig will be implemented into the existing simulation model so that optimal operating conditions considering both process energy efficiency and solvent degradation can be determined.

[more ▼]Although Bharati Mukherjee is famous, or rather infamous, for her shameless embrace of America and its melting-pot ideology, in Desirable Daughters India, the homeland, is unexpectedly made to re-enter the stage of immigrant identity construction. In many respects it would seem that it has now become untenable to represent immigrant identity in terms of a one-directional movement from “India” to “America.” In Desirable Daughters the rise of India, the accelerated time/space compression of late capitalism, the post-90s paradigm shift in matters of transnational migration, the emphasis on return migrations and the emergence of a new global interaction indeed dramatically outflank Mukherjee’s previous narrative of American “exceptionalism” – which suddenly seems dated by comparison. By portraying the complex transnational network of connections operating between RIs (Resident Indians) and NRIs (Non Resident Indians), Mukherjee’s book gestures towards the “de-spatialization” of immigrant identity construction and its consequent “re-metaphorization” in terms of “time zones.” What is more, the increasingly compelling influence of contemporary India on the Indo-American diasporic subjectivity marks a “back to the future” return of the repressed which temporally repositions migrant identity between a ghostly time of repetition and a “hauntology” of new becomings. What Mukherjee suggests, I will contend, is that immigrant agency and self-fashioning cannot be associated anymore with the “pioneering spirit” of forward-looking characters that discard their “Indianness” upon (geographical) entry into the West. In my reading of Desirable Daughters the protagonist’s zigzagging path to self-transformation will be emphasized, so that it will become apparent that time has become the fourth space through which new spaces for diasporic identity can be renegotiated.
