The aim of this study was to evaluate the physico-chemical stability of Belgian Blue beef packaged under high-oxygen atmosphere as a function of a previous aging technique (wet-aging in vacuum conditions vs. carcass-aging). Two muscles (longissimus dorsi vs. rectus femoris) were studied. After a seven-day wet- or carcass-aging step, muscle cuts from 4 Belgian Blue cows were vacuum packaged and stored at −1 °C for up to 28 days. Each 14 days, part of these samples was repackaged under modified atmosphere (70 % O2:30 % CO2), and stored during 7 days at +4 °C. The following parameters were evaluated: color, metmyoglobin %, metmyoglobin reducing activity, fat content, fatty acid profile, lipid oxidation, antioxidant enzyme activities and alpha-tocopherol content. The sensitivity of modified atmosphere repacked meat cuts to oxidation was influenced by the conditions of the previous aging period (wet > carcass conditions), muscle (rectus femoris > longissimus dorsi) and length of the vacuum storage.

Many countries and regions in Europe are nowadays setting up biobased economy strategies and action plans. For Belgium, the case of the Walloon region is discussed in this talk through a SWOT analysis. Even if a large part of the territory is covered by agricultural and forestry productions, the feedstock supply and availability are rather restricted. However, in order to stimulate the development of biorefineries in the Walloon region, it is important to support a reliable upstream supply chain. Therefore, several options are currently evaluated by the government, the industrial sectors and academic/research centers and presented herein through several pilot, R&D or industrial initiatives.

Dans la plupart des familles de Cotonou, l’héritage est source de conflits. Qu’il s’agisse de frères et sœurs et de la gestion du patrimoine commun, d’un administrateur qui accapare l’ensemble des ressources, d’une veuve chassée par les enfants de ses coépouses, chaque famille fait l’objet d’une anecdote, de tensions latentes ou de conflits ouverts. Si certains n’hésitent pas à saisir les tribunaux, la justice constitue la plupart du temps le dernier recours. En cas de désaccord, quelles sont les démarches entreprises avant le tribunal? Il existe une série d’instances de médiation en matière familiale, depuis les sages de la famille ou du village, jusqu’aux tribunaux de conciliation ou aux ONG d’assistance juridique. Comment les héritiers choisissent-ils le forum auquel s’adresser ? Je m’intéresserai également au fonctionnement de ces institutions parajudiciaires, à la manière dont le droit y est mobilisé, dont les conflits y sont résolus ou renvoyés vers les tribunaux.

Measurements of the atmospheric HDO/H2O ratio help us to better understand the hydrological cycle and improve models to correctly simulate tropospheric humidity and therefore climate change. We present an updated version of the column-averaged HDO/H2O ratio dataset from the SCanning Imaging Absorption spectroMeter for Atmospheric CHartographY (SCIAMACHY). The dataset is extended with two additional years, now covering 2003–2007, and is validated against co-located ground-based total column delta-D measurements from Fourier-Transform Spectrometers (FTS) of the Total Carbon Column Observing Network (TCCON) and the Network for the Detection of Atmospheric Composition Change (NDACC, produced within the framework of the MUSICA project). Even though the time overlap between the available data is not yet ideal, we determined a mean negative bias in SCIAMACHY delta-D of -35±30‰ compared to TCCON and -69±15‰ compared to MUSICA (the uncertainty indicating the station-to-station standard deviation). The bias shows a latitudinal dependency, being largest (about -60 to -80‰) at the highest latitudes and smallest (about -20 to -30‰) at the lowest latitudes. We have tested the impact of an offset correction to the SCIAMACHY HDO and H2O columns. This correction leads to a humidity and latitude dependent shift in delta-D and an improvement of the bias by 27 ‰, although it does not lead to an improved correlation with the FTS measurements nor to a strong reduction of the latitudinal dependency of the bias. The correction might be an improvement for dry, high-altitude areas, such as the Tibetan Plateau and the Andes region. For these areas, however, validation is currently impossible due to a lack of ground stations. The mean standard deviation of single-sounding SCIAMACHY–FTS differences is ~115 ‰, which is reduced by a factor ~2 when we consider monthly means. When we relax the strict matching of individual measurements and focus on the mean seasonalities using all available FTS data, we find that the correlation coefficients between SCIAMACHY and the FTS networks improve from 0.2 to 0.7–0.8. Certain ground stations show a clear asymmetry in delta-D during the transition from the dry to the wet season and back, which is also detected by SCIAMACHY. This asymmetry points to a transition in the source region temperature or location of the water vapor, and shows the added information that HDO/H2O measurements provide, if used in combination with variations in humidity.

The prevalence of valvular heart diseases reaches 2.5% in the overall population. Aortic valve replacement is one of the most common surgical procedures. We report the story of a female patient whose aortic mechanical valve, implanted at the age of 54 years at the time of a mitral valve repair surgery, had to be replaced 14 years later, due to the development of a subvalvular pannus narrowing the valvular orifice. We use this clinical story to compare the advantages and disadvantages of repair surgery and valve replacement with a biological or mechanical prosthesis, and summarize the latest evidence for the choice of the most adequate prosthesis for a particular patient’s profile.

The documentation of the cultural heritage is a concern since 1885, with the first application of photogrammetry techniques by Albrecht Meydenbauer. In 1987, The International Council of Monuments and sites has recommended the creation of photogrammetry records of monuments and archaeological sites. Since then, the close range photogrammetry has been the most used technique to survey cultural heritage. This technique has become faster and more accessible with the advancement of digital cameras. Despite the recommendations of International Council of Monuments and sites, the advent of new technologies and the importance of a quality evaluation and documentation, there are few studies with a rigorous analysis of the requirements for the cultural heritage documentation, with focus on the geometry of the models generated by digital photogrammetry process. The aim of this work is to propose discussions and analysis of requirements for the evaluation of planimetric quality of photogrammetric projects applied to the cultural heritage documentation.

When one wants to compare the homogeneity of a characteristic in several popula- tions that have di erent means, the advocated statistic is the univariate coe cient of variation. However, in the multivariate setting, comparing marginal coe cients may be inconclusive. Therefore, several extensions that summarize multivariate relative dispersion in one single in- dex have been proposed in the literature (see Albert & Zhang, 2010, for a review). In this poster, focus is on a particular extension, due to Voinov & Nikulin (1996), based on the Mahalanobis distance between the mean and the origin of the design space. Some arguments are outlined for justifying this choice. Then, properties of its sample version under elliptical symmetry are discussed. Under normality, this estimator is shown to be biased at nite samples. In order to overcome this drawback, two bias corrections are proposed. Moreover, the empirical estimator also su ers from a lack of robustness, which is illustrated by means of in uence functions. A robust counterpart based on the Minimum Covariance Determinant estimator is advocated. [less ▲]

The effects of urban sprawl have been well documented, particularly regarding energy consumption. Suburban neighbourhoods are known to be energy inefficient and urban sprawl is considered as a major issue for sustainable development. To improve the energy efficiency of existing suburban urban fabrics is a major challenge that must be addressed to favour a sustainability transition of our built environment. In this context, this paper aims at investigating several scenarios that could be developed to improve the sustainability of existing suburban neighbourhoods: three main types of scenarios (building insulation, density, and urban form) and twelve sub-scenarios, which are focused on the possible evolution of the existing suburban building stocks, are proposed. Quantitative methods developed in previous research are used to assess and compare building and transportation energy consumption of a representative suburban case study. This application aims at investigating two main research questions: (1) "how to intervene in suburban neighbourhoods?" and (2) «where to intervene?" The main results of this application, which are focused on energy efficiency, are then studied in a larger framework to highlight their opportunities and constraints. The main findings of the paper are that, beyond the traditional polarisation of the debates on the energy efficiency of our built environment between the “compact” and the “sprawled” city, a new pragmatic paradigm, which is focused on the smooth densification of existing suburban neighbourhoods, can make them evolve towards greater sustainability.
