In an interview closely following on the release of The History of Love, Krauss made it clear that, contrary to what some critics had ventured, her second novel was not about Holocaust survivors. “I am the grandchild of people who survived that historical event,” Krauss pointed out. “I’m not writing their story – I couldn’t write their story […]. What interests me is the response to catastrophic loss.” Great House, Krauss’s third novel, can be seen to further investigate this “response to catastrophic loss” – in a way which makes only tangential and mediated references to the Holocaust. The novel spans eighty years, starting from the near-end of World War 2, and traces the passing-on of a desk of massive proportions. Complete with nineteen drawers, one of which remains locked until it is symbolically revealed to be empty at the close of the book, the desk operates as some kind of trans-historical fetish for most of its successive keepers (and aspiring acquirers). Narrated through a set of five characters whose lives prove overshadowed less by the Holocaust itself than by its felt resonances in the psyches of loved ones, Great House is a polyphonic work that raises questions about the anatomy of ‘Holocaust postmemory’ (Marianne Hirsch), its temporality, but also its reification in conformity with defense mechanisms that take the form of death-denying fantasies. Here, while turning to the past, some clearly unreliable first-person narrators reveal their lifelong investment in fetishizing memories of themselves and others so as to better keep all sense of temporality and mortality at bay – in a way suggesting that fantasies of un-death have helped them fill in the gap left by the unspeakable horror of the Holocaust, and were later transmitted in lieu of ‘memory proper’. This paper will thus focus on Great House’s rich imagery, and its narrative strategies, in order to investigate Krauss’ representation of the paradoxes of Holocaust postmemory. [less ▲]

As an economical and feasible intervention, reflection demands learners using critical thinking to examine presented information, questioning its validity, and drawing conclusions based on the resulting ideas during a learning process. The aim of this study is to gain insight into the effects of practicing short, frequent and structured reflective breaks that are interspersed with the reading process of a learning material. It tries to reveal whether physiological signals can be used as appropriate indicators to reveal the actual changes of cognitive states while introducing different reflective breaks during learning. The recorded physiological signals include skin temperature, blood volume pulse, pulse volume amplitude, and pulse rate. The results show that while these embedded “reflection rituals” did not affect learners’ performance they had significantly impact on time on task, perceived learning and those learners' physiological (cognitive) states. Physiological data returned significant differences between the reading and reflection activity. Measurements of temperature and pulse rate are lower when covering the course equipped with additional reflection affordances while blood volume pulse and pulse volume amplitude are higher. In addition, applying statistics analysis to the physiological data exhumes significant differences between different types of reflection activities for those measurements including skin temperature, pulse volume amplitude and pulse.

Thermography, shearography and laser ultrasonics are 3 contactless emerging techniques which allow nondestructive inspection of composite structures. Thermography and shearography are full-field techniques yielding measurement of respectively local temperature variations or deformations of a structure undergoing a stress (thermal, pressure, vibration). Laser ultrasonics allows remote ultrasound generation in the composite by thermoelastic effect followed by remote measurement of the surface displacements under the effect of the ultrasound echoes without coupling. This point-like technique requires scanning. The three techniques have been selected in our project since they allow inspection of complex shaped parts. We present compared results obtained on a variety of aeronautical industrial composite parts. [less ▲]

Recent progress in the seismic interpretation of field β Cep stars has resulted in improvements of the physical description in the stellar structure and evolution model computations of massive stars. Further asteroseismic constraints can be obtained from studying ensembles of stars in a young open cluster, which all have similar age, distance, and chemical composition. We present an observational asteroseismology study based on the discovery of numerous multi-periodic and mono-periodic B stars in the open cluster NGC 884. We describe a thorough investigation of the pulsational properties of all B-type stars in the cluster. Overall, our detailed frequency analysis resulted in 115 detected frequencies in 65 stars. We found 36 mono-periodic, 16 bi-periodic, 10 tri-periodic, and 2 quadru-periodic stars and one star with nine independent frequencies. We also derived the amplitudes and phases of all detected frequencies in the U, B, V, and I filter, if available. We achieved unambiguous identifications of the mode degree for 12 of the detected frequencies in nine of the pulsators. Imposing the identified degrees and measured frequencies of the radial, dipole, and quadrupole modes of five pulsators led to a seismic cluster age estimate of log (age/yr) = 7.12-7.28 from a comparison with stellar models. Our study is a proof-of-concept for and illustrates the current status of ensemble asteroseismology of a young open cluster. [less ▲]

Dans cette intervention, nous posons la question de la métamorphose des rapports entre citoyens et institutions suite au développement des NTIC, à travers l’exemple de la plateforme d’observation de la biodiversité Observations.be et de l’Institut Bruxellois de Gestion de l’Environnement à Bruxelles (IBGE). Nous nous intéressons surtout à voir si, comme le signale Charvolin (2009), une meilleure maîtrise des pratiques de la recherche – dans notre cas à travers les NTIC – peut réellement mettre à pied d’égalité amateur et expert. Nos réflexions ici s’appuient sur des entretiens, notamment auprès des gestionnaires du dossier biodiversité à l’IBGE et des administrateurs d’Observations.be, ainsi que sur l’analyse des fonctionnalités du site lui-même.

Hydrogen (H2) is being considered as an ideal and clean energy carrier since the utilization of hydrogen, either via combustion or via fuel cells, results in pure water. However, currently its production relies mainly (i.e. 95%) on fossil fuels. The recent advances to produce biohydrogen from renewable sources such as biomass and particularly by fermentation of carbohydrate-rich substrates from agriculture and agro-industries appear promising. Such a process called “dark fermentation” enables both organic waste treatment and renewable energy production to be coupled. The soluble metabolites, mainly acetate and butyrate, contained in the spent medium of the dark fermentation bioreactor may be efficiently converted to methane in a second anaerobic digester treating other carbon sources. The paper reviews the state-of-the art on the challenges and prospective applications of dark fermentation as a first step of anaerobic digestion of municipal solid wastes to produce H2 and CH4.
