Introduction In Europe, about 400,000 people have a sudden cardiac arrest every year, with a survival rate of 5-10% (ERC, 2015). Bystander cardiopulmonary resuscitation (CPR) could increase this survival rate by 2-3 times. Unfortunately, less than 20% of the general population is able to perform it effectively (Plant & Taylor, 2013). Besides, most of the public facilities are now equipped with automated external defibrillators (AEDs). In a physical literacy perspective (Whitehead, 2013), PE teachers are ideally placed to teach basic life support (BLS) to their students (Colquhoun, 2012). Methods In this pilot study, a female PE teacher was trained to a BLS cycle adapted to the PE curriculum. The BLS cycle, including 6 sessions of PE, was developed in a participatory approach by a team of BLS specialists, PE teacher educators and by the PE teacher herself. During this BLS cycle, students learned the CPR & AED protocols, taught by different teaching styles (practice, reciprocal, self-check) with hands-on application on training manikin and AED. A process analysis was performed from the video recording of the sessions and from satisfactory questionnaires. Students’ knowledge of the BLS protocol was assessed by a 14 open-ended questionnaire at baseline (T0) and after the intervention (T1). Practical application of the BLS protocol was assessed on a manikin measuring CPR performance at T1. Results and conclusions The BLS program was taught to two classes of high school female students (n=52), aged 17.1 ± 0.3 years. At T0, if students were mostly aware of the emergency number (71.4%), very few were able to localise the chest compression (14.3%) and AEDs’ electrodes (2%) areas. Most of them did not feel able to perform BLS (89.8%) and would agree to learn it during PE lessons (97.9%). Results at T1 are expected to highlight improvements of the theoretical and practical BLS’ competencies of the students. [less ▲]

This work provides a framework to evaluate the response of buildings in a community to fire following earthquake. As part of the framework, the paper discusses two methodologies: (1) how to develop fire fragility functions; (2) how the fire fragility functions can be used in conjunction with an original fire ignition model to estimate the potential losses in a community from fire following earthquake. The paper focuses in particular on the development of fire fragility functions for an entire building to measure the probability of reaching a damage state given a fire scenario. Next, the paper proposes an ignition model to evaluate the probability of fire ignition after an earthquake. The ignition model together with fragility functions measure the probability of damage from fire following earthquake given an earthquake scenario. [less ▲]

At Koksijde in Belgium a severe fire took place in an apartment building in 2015, resulting in the death of a young man and visible structural damage to four balconies. Following the fire, experts were mandated to assess the damage and the need for structural repair. They estimated that the balconies had to be refurbished but that there were no other structural elements affected, in particular the slab inside the apartment could be left in place with only a surface treatment and new plaster finishing. However, the floor slab in the apartment located above the fire apartment exhibited several visual indications that the fire could have had a structural impact, such as residual deformations and cracks in the tiles. This paper presents a methodology to infer the fire severity based on post-fire measurements and non-linear thermo-plastic numerical simulations. Finally, knowing the fire severity, its effect on the structure is evaluated and a reliability-based assessment is made of the residual load bearing capacity of the slab. [less ▲]

Fire fragility functions can be used to characterize the probabilistic vulnerability of buildings to fire in the context of urban resilience assessment. A methodology has been proposed to develop such functions for multi-story steel buildings. However, a large number of parameters with uncertainties play a role in the process of constructing the fragility functions. The goal of this research is to identify the critical parameters that most affect the global fire safety by investigating the sensitivity of the fragility functions to different input parameters. Sensitivity in parameters affecting the fire model, the heat transfer process and the thermo-mechanical response is examined. The effects of different design assumptions at the system level are also studied. The presented approach is useful for selecting the prevailing parameters in a fire reliability analysis and it provides important information for modeling tools that can be used to evaluate resilience for fire scenarios.

Hybrid testing is an appealing technique to observe the behavior of an element in an experimental test while taking into account the interaction with the rest of the structure which is modelled numerically. Being widely used in the seismic field, this technique has been recently proposed in the fire field. The purpose of this paper is to demonstrate that the loading control process may be unstable during the hybrid testing when using the methodology applied in former tests presented in the literature. The stability in the latter method depends on the stiffness ratio between the two substructures. For the purpose of discussion, a one degree-of-freedom elastic system is studied. To overcome the stability issues, a new method is presented, independent on the stiffness ratio. Finally, the hybrid testing of a 2D beam being part of a moment resisting frame is analyzed in a virtual environment (both parts being modeled numerically) using the “first generation method” and the new proposed method.

This contribution aims to present and discuss my thesis project. I plan to study the concrete conditions of production, diffusion and reception of knowledges on digital scholarly platforms in Humanities. This work will especially focus on the four plateforms of the portal OpenEdition: OpenEdition Books, Calenda, Hypothèses and Revues.org. The main problematic is: what are the uses of those platforms, and in what concrete way are they influencing the modes of scientific communication? To start with, I need to highlight the frameworks that structure the digital scholarly texts, that Jeanneret named ‘architexts’ (Davallon & al. 2003, Jeanneret 2014). Such frameworks contribute to configure the digital texts (e. g. with hypertext, flows aggregation), and their uses. Three aspects will then be taken into consideration in my analysis: (I) the articulation of temporal stratums within the plateform: how do archival materials deal with actualities (scientific monitoring, work in progress as grey literature)? What means of contextualization (Treleani 2013) or editorialization (Vitali Rosati 2016) could be given when an old document is used again (e.g. in “epi-revues” that collect scientific papers) ? (II) What are the genres and formats conveyed on the plateform, proper to the Web as blog post, commentary, etc., or still used in other medias as scientific article, advert, etc. (Maingueneau 2013)? (III) Who are the users of those plateforms (researchers, groups, professionals, etc.)? How do they deal with their digital identities? How can they appropriate and diffusing knowledges, by citing, reusing and discussing? How are emerging new ways for research in Humanities, through collective negociation or evaluation, interdisciplinarity – such actions that could be promoted by the technical device of the plateform? This last point will be treated by a philological approach concerning paratexts and quotations (Genette 1982, Compagnon 1979). Other indicators (users’ itineraries, interactions between members, etc.) could also be used, and treated with network’s visualization tool. In summary, this research project aims to explore the means of a digital philology (Crane, Bamann and Jonesin Schreibman 2008; Rastier 2011), not only based on making traditional philology with digital tools (i.e. semantic enrichment of antics or medieval texts), but also on a critical approach of the digital textuality and on an active as well as reflexive contribution from the users in building knowledges.

Large-scale atmospheric circulation controls the mass and energy balance of the Greenland ice sheet through its impact on radiative budget, runoff and accumulation. Here, using reanalysis data and the outputs of a regional climate model, we show that the persistence of an exceptional atmospheric ridge, centred over the Arctic Ocean, was responsible for a poleward shift of runoff, albedo and surface temperature records over the Greenland during the summer of 2015. New records of monthly mean zonal winds at 500 hPa and of the maximum latitude of ridge peaks of the 5,700±50 m isohypse over the Arctic were associated with the formation and persistency of a cutoff high. The unprecedented (1948–2015) and sustained atmospheric conditions promoted enhanced runoff, increased the surface temperatures and decreased the albedo in northern Greenland, while inhibiting melting in the south, where new melting records were set over the past decade.

When studying micro-electro-mechanical systems (MEMS) made of poly-crystalline materials, as the size of the device is only one or two orders of magnitude higher than the size of the the grains, the structural properties exhibit a scatter at the macro-scale due to the existing randomness in the grain size, grain orientation, surface roughness... In order to predict the probabilistic behavior at the structural scale, the authors have recently developed a stochastic 3-scale approach [1]. In this method, stochastic volume elements (SVEs) [2] are defined by considering random grain orientations in a tessellation. For each SVE realization, a meso-scopic apparent material tensor can be obtained using the computational homogenization theory. The extracted meso-scopic apparent material tensors can then be used to defined a spatially correlated meso-scale random field, which is in turn used as input for stochastic finite element simulations. In this work we intend to study the effect of different material-related uncertainty sources on the structural behavior of vibrating micro-devices manufactured using low pressure chemical vapor deposition. First, the effect of preferred grain orientation on vibrating micro-structures is assessed. To this end, SVEs are generated so that their grain orientation distributions follow XRD measurements. Second, the effect of the roughness of the vibrating micro-structures is studied. Toward this end, SVEs, whose rough surface statistical properties follow AFM measurements, are generated. A second-order computational homogenization [3] applied on the different SVE realizations allows defining a meso-scale random field of the in-plane and out-of-plane meso-scale shell properties. Stochastic shell finite elements can then be applied to predict the MEMS probabilistic behavior. [1] V. Lucas, et al., Comp. Meth. in Appl. Mech. and Eng., 294, 141-167, 2015 [2] M.

Introduction A single tumoral tissue can bear phenotypically different cell populations. This phenomenon called intra-tumor heterogeneity can lead to differential behaviors regarding metastasis seeding and therapy resistance [Zardavas et al., Nature Rev. Clin. Onc. 2015]. MALDI imaging has proven its efficiency for revealing hidden molecular features offering an insight into distinct cellular regions based on their molecular content. Further, proteomics applied to these regions could allow depicting the molecular context associated to particular cells groups and enable the collection of qualitative, quantitative and spatial information for each protein. Methods Breast cancer Formalin Fixed and Paraffin Embedded tissues, from patients whose outcome had been recorded over a period of 10 years, were provided by the department of Pathology of University of Liège. After Citric Acid Antigen Retrieval and trypsin digestion, images were obtained by MALDI-TOF/TOF-MS (Bruker, Germany). From the obtained datasets, segmentation and analytical data analysis were applied using SCiLS (Bruker, Germany) and the cloud software Multimaging (ImaBiotech, France). Small tissue areas were obtained by laser microdissection (LEICA LMD 700, Germany), upon which a combination of chemical processes was applied to ensure optimal protein antigen retrieval, extraction and digestion. Finally, the tissue pieces obtained were analyzed by LC-MS/MS using UPLC Waters Nanoacquity and Thermo Q-Exactive instruments. Preliminary data Based on mathematical calculations for the MALDI imaging datasets of the breast cancer FFPE tissues, Regions Of Interest (ROIs) were detected in a single tumor, revealing intra-tumoral heterogeneity, which can be correlated to the level of aggressiveness of the affliction and to the final prognosis of the patient. We aimed to compare the proteomic profiles of each of the small ROIs. Until today, proteomics applied to tissues composed by a restricted number of cells is quite tedious due to possible tissue losses during their handling. Recently, Longuespée [Longuespée et al., Methods 2015] published a method in order to retrieve the identification of 1400 proteins from microdissected tissue pieces containing only 2700 cells. This whole procedure allowed us to identify a panel of protein that characterizes tissue heterogeneity within a single tumor. This proves the applicability of the combination of MALDI imaging for the discovery of intra-tumoral heterogeneity without a priori, on a mathematical basis, and classical proteomics applied on laser-microdissected tissue samples of very restricted areas. This method will now be applied to several MALDI datasets in order to retrieve commune ROIs and to associate their presence with the information of each patient, such as their prognosis. Those ROIs will then be microdissected and subjected to microproteomic methods that will allow us to retrieve the extensive molecular context associated to bad patient prognosis and/or therapy resistance. The possibility to identify protein/peptide markers will have the power to predict the outcome of the breast cancer patient at the beginning of their treatment, and thus, improve the clinical care for the benefit of the patients. Novel aspect The workflow combines the unique advantages of MALDI imaging for de novo molecular features characterization and LMD-based microproteomics. [less ▲]
