The objective of this paper is to investigate the respective influence of various urban pattern characteristics on inundation flow. A set of 2,000 synthetic urban patterns were generated using an urban procedural model providing locations and shapes of streets and buildings over a square domain of 1 x 1 km². Steady two-dimensional hydraulic computations were performed over the 2,000 urban patterns with identical hydraulic boundary conditions. To run such a large amount of simulations, the computational efficiency of the hydraulic model was improved by using an anisotropic porosity model. This model computes on relatively coarse computational cells, but preserves information from the detailed topographic data through porosity parameters. Relationships between urban characteristics and the computed inundation water depths have been based on multiple linear regressions. Finally, a simple mechanistic model based on two district-scale porosity parameters, combining several urban characteristics, is shown to capture satisfactorily the influence of urban characteristics on inundation water depths. The findings of this study give guidelines for more flood-resilient urban planning. [less ▲]

The paper explores the interaction between different kinds of social agents in the funding and management of cult foundations for the dead in the late-classical and Hellenistic period. Textual and archaeological dossiers will be discussed in order to 1) investigate the occupation of sacred space in existing sanctuaries and other public spaces as well as the creation of new sacred places, specifically meant to host ritual practice for dead individuals or groups; 2) provide a comparative analysis of the patterns of establishment, funding and management of cult foundations pertaining to civic, royal, individual or groups' initiatives; 3) explore the forms of interaction between various agents involved, e.g. between civic and private initiative in funding and management. When possible, these considerations will also be integrated with an evaluation of the religious status attributed to the honoured persons, with particular attention to the semantic fields of heroization and deification. Thus an attempt will be made at tracking down possible general trends of religious administration beyond local particularities, and at schematizing these configurations in a model taking into account four factors: the social status of ritual agents and recipients; the religious status acknowledged to cult recipients; the methods of funding and management; the degree of monumentalization and social impact of the cult foundations.

Structural fire engineering has long relied on a prescriptive approach based on isolated member behavior under continuously heating standard fire. By definition, this approach does not allow comprehending the effects of interaction between members of a complete structure nor the effects of real fire exposure. Yet, such effects can have a significant influence on the response of real buildings to fire. Notably, when a structure has survived a fully developed fire, the cooling phase that inevitably follows generates effects that may endanger the structure stability. This has been attested by real structural collapses and poses a specific threat to firefighters. However, the behavior of structures under natural fire and the causes of failure during cooling are still not well understood. This research investigates the response of steel-framed structures to natural fires with the aim to analyze the possible collapse mechanisms during cooling. Numerical simulations by nonlinear finite element method are conducted for different fire scenarios and structural designs. The simulations model the thermo-mechanical behavior of the frames accounting for the interaction between members during the entire fire duration until burnout. Different collapse mechanisms during cooling are highlighted and discussed, including connection failure and progressive collapse under localized fire. In the latter case, collapse of members not directly affected by the fire occurs during the cooling phase. These mechanisms result from a complex combination of several factors, such as the recovery of thermal elongation, the recovery of stiffness, and the prior development of permanent strains in the heated members. The results show that steel-framed structures are subject to collapse during the cooling phase of natural fires. Therefore, natural fires with heating-cooling sequences represent a loading case that should be considered in structural fire analyses and could lead to specific design provisions to prevent the occurrence of collapse during cooling.

Feed sustainability is one of the biggest challenges for the next few years. Solutions have to be found that take feed quality and safety into account. Animal by-products are one valuable source of proteins. However, since the bovine spongiform encephalopathy (BSE) crisis, their use has been strictly regulated. The objective of this study was to propose a routine, sensitive and specific method using ultra-high performance liquid chromatography coupled to tandem mass spectrometry for the detection of blood-derived products and milk powder in feed. Contaminated aquafeeds were analysed in order to evaluate the sensitivity and specificity of the method. This new method meets both selectivity and sensitivity (0.1% (w/w)) requirements imposed by the European Commission for animal proteins detection methods. It offers an innovative and complementary solution for the simultaneously identification of authorised and unauthorised animal by-products such as processed animal proteins (PAPs). [less ▲]

Charcoal production in forests is one of the oldest forms of forest exploitation. The legacy of such once widespread activity is a plethora of relic charcoal hearths (RCHs1), where soil shows a thick, black, charcoal-rich top horizon. Even where very common, such as in European forests, RCHs were rarely studied to assess their relevance as C reservoir. For this purpose, as a case study, we investigated some RCHs at Marsiliana, a typical Mediterranean oak forest from Central Italy. We found that RCHs soils, in spite of representing < 0.5% of total surface, gave a substantial contribution in terms of C, i.e. 1.1% to 4.2% of total ecosystem C, including litter, the top 30 cm of soil, deadwood, above-ground and below-ground biomass. On average, soil C content in RCHs was eight times higher than the soil outside the RCHs. The environmental significance of RCHs soils appears still greater considering that, on average, 43% of their C stock was charcoal, a form of C highly recalcitrant to mineralization. These results would stress the importance of accounting for the contribution of RCHs in terms of soil C and giving an estimation of their charcoal content in future C inventories, both as macroscopic and microscopic particles in soil. This study support the necessity of safeguarding the anthropogenic soils of RCHs as a precious C reservoir as well as a memory of past land uses. [less ▲]

Aims: SNOT-22 was initially designed for rhinosinusitis, but was recenty validated in various nose conditions. Nose or sinus complaint is a common cause of consultation in primary care or ENT clinic. Therefore we sought to optimize the simple and versatile instrument SNOT-22. Our aim was to determine the outcome of patients and healthy volunteers solely based on the pattern of the baseline SNOT-22 in a multi-centre study. Methods: Sixty-six healthy volunteers and 383 patients presenting to the rhinology clinic of the ENT academic departments of Godinne, Liege and Brussels participated in this study. SNOT-22 from all participants were collected blindly prior to diagnosis. Participants were then categorized in 5 groups according to their outcome: control, medical rhinologic condition, sinus surgery, functional nose surgery. SNOT-22 items relevant to each group were determined by multinomial logistic regression. Results: Control subjects showed the lowest SNOT-22 scores for all items. Medical rhinologic patients had lower scores than surgical patients. Patients requiring sinus surgery and those listed for nose surgery exhibited a specific pattern of SNOT-22 score. Most relevant items were #1 need to blow nose, #5 post-nasal discharge, #6 thick nasal discharge, #10 facial pain and #21 sense of smell. Conclusions: Distinct SNOT-22 patterns were correlated to subjects outcome. SNOT-22 was able to differentiate patients from controls, to score severity, and could further provide an accurate description of pathology. Baseline SNOT-22 could localize pathology in the sinus or in the nose and predict the need for surgical treatment. [less ▲]

Aims: Increasing pressure to reduce healthcare cost threatens the provision of acute ENT coverage round the clock. Our goal was to audit our emergency rhinologic activity over a one-month period. Methods: A prospective audit for all emergency ENT referrals was carried out from May 1st to May 31th 2017. Descriptive statistics were produced for age, sex, origin, time of arrival, diagnosis and outcome. A specific subgroup analysis was performed for rhinologic emergencies. A basic cost analysis was ran. Results: Over the study period, 190 patients were referred to the ENT emergency service. Twenty percent patients presented with nose or sinus complaint (36.8% with otological or neuro-vestibular primary complaint, 43.2% with laryngeal or neck complaint). Nose and throat complaints were more likely to present at night or on weekends. Ear complaints were more likely to present during business hours. Rhinologic complaint was more likely to require technical or surgical management than ear or throat complaint. Patients with nose complaint required minor procedure in 43.2% cases (35.6% of the total minor procedures), and required surgical procedure in 13.5% cases. Among the total ENT emergency surgical procedures, 62.5% were rhinologic ones, involving the nose (50%) or the sinus (12.5%). Ear or throat initial complaint were more likely to require no treatment or ambulatory management. Conclusion: The emergency rhinologic activity is justified in our hospital. An initial rhinological complaint was more likely to require specific ENT management than other complaints. ENT cover is an efficient service provision, especially for rhinologic emergencies.

Les études consacrées aux interventions de Sartre dans les médias dressent le portrait d’un philosophe frileux à l’égard de la radio, un médium réputé « à sens unique » conformément aux commentaires qu’il en aurait livré dans sa Critique de la raison dialectique. Il n’est pas étonnant dès lors que ces études se satisfont d’une approche essentiellement textuelle de ces interventions et manquent ainsi les usages singuliers que Sartre a fait de ses passages en radio. Partant d’extraits d’interventions enregistrées entre 1946 et 1973, la conférence et projection sonore Réagir à l’archive. Sartre et la radio entend contester l’image d’un philosophe rétif au médium radiophonique tout en dépassant la réduction de ses interventions sonores à leur seule retranscription textuelle. Le rythme des réponses du penseur, leur longueur, le jeu avec l’interviewer dont elles portent les traces, mais aussi les multiples références au direct de l’entretien radiophonique et à la réalité du moment de la diffusion témoignent en effet d’un usage extrêmement lucide d’un médium dont Sartre a tenté d’exploiter toutes les potentialités intellectuelles et politiques propres. On découvrira ainsi qu’avant d’être un matériau d’archive effacé par le texte, les interventions radiodiffusées du philosophe ont été autant de tentatives de (se) jouer de la spécificité radiophonique pour inscrire la pensée critique au cœur même du dispositif médiatique.

Background and objective of the work. Ghrh-/- mice with a severe deficiency of their somatotrope GHRH/GH/IGF1 axis (1) are resistant to experimental allergic encephalomyelitis (2). In basal conditions, thymus and T-cell development are not severely affected but a marked spleen atrophy and B-cell lymphopenia were constantly observed (3). Therefore, we investigated vaccinal and anti-infectious responses of Ghrh-/- mice against S.pneumoniae, a T-independent pathogen. Results. Transgenic mice were unable to trigger production of specific IgM after vaccination with either native pneumococcal polysaccharides (PPS, Pnx23) or protein-PPS conjugate (Prev13). GH treatment of Ghrh-/- mice restored IgM response to Pnx23 vaccine but not to Prev13 suggesting that GH exerts a significant impact on the spleen marginal zone that is strongly implicated in T-independent immunological response to pneumococcal polysaccharides. After intranasal instillation of a non-lethal dose of S.pneumoniae, Ghrh-/- mice exhibited a dramatic susceptibility with a time-dependent increase in lung bacterial load, a bacteremia already after 24h, and a survival limit of 48-72h. In marked contrast, WT and heterozygote mice completely cleared S.pneumoniae infection after 24h. Lungs of infected Ghrh-/- mice were massively infiltrated by inflammatory macrophages, while lung B cells were markedly decreased. Transcription of Ifng, Il10, Cd40, and Cxcl9 was highly increased in the lungs of infected Ghrh-/- mice, whereas Tgfb and Iggj transcripts were unchanged. Resistance of Ghrh-/- mice to infection by influenzavirus H1N1 (a T-dependent antigen) was normal or slightly decreased. Conclusion. This animal model shows that the somatotrope GHRH/GH/IGF1 axis plays a vital and unsuspected role in the vaccine and immunological defense against S.pneumoniae. [less ▲]
