Purpose: This paper describes the theoretical background and main hypotheses at the basis of SAFIR®, a nonlinear finite element software for modeling structures in fire. The paper also explains how to use the software at its full extent. The discussed numerical modeling principles can be applied with other similar software. Approach: Following a general overview of the organization of the software, the thermal analysis part is explained, with the basic equations and the different possibilities to apply thermal boundary conditions (compartment fire, localized fire, etc.). Next, the mechanical analysis part is detailed, including the time integration procedures and the different types of finite elements: beam, truss, shell, spring and solid. Finally, the material laws are described. The software capabilities and limitations are discussed throughout the paper. Findings: By accommodating multiple types of finite elements and materials, by allowing the user to consider virtually any section type and to input the fire attack in multiple forms, the software SAFIR® is a comprehensive tool for investigating the behavior of structures in the fire situation. Meanwhile, being developed exclusively for its well-defined field of application, it remains relatively easy to use. Value: The paper will improve the knowledge of readers (researchers, designers and authorities) about numerical modeling used in structural fire engineering in general and the capabilities of a particular software largely used in the fire engineering community.

From both a scientific and a practical point of view, two major trends seem to presently rule the adult training field: the psychosociological trend and the ergonomic trend. Though each one has widely contributed in developing training in organizational human resources development, we fail to see any significant level of understanding between the two trends or any dialogue based on scientific objectivity. The aim of this present paper is to hopefully initiate a dialogue with an eye towards development in training practices. A better understanding of these main approaches would bring help to those who seek to train personnel and to better orientate their choice of training. [less ▲]

Science and technology require an intervention by the law, and law is called upon to intervene in front of their evolution, and to look for proper solutions of governance and rational responses to their risks. One of the main issues to be investigated from the legal viewpoint is represented by the ‘dual-use dilemma’ that arises both in ‘traditional’ and new areas of techno-sciences. Indeed, any kind of research has the potential to be used both for bad as well as for good purposes. Therefore, it is important to reflect upon the ways to control possibly dangerous research without preventing the progress from going further. Such ‘dual-use dilemma’, then, entails the study of one of the fundamental freedoms in the biolaw area: the freedom of scientific research, its limits, and relationship with other rights/needs/freedoms (such the need of security). This work focuses on two areas of the techno-scientific world. One is more ‘traditional’, i.e. nuclear science, in whose context the reflections on ‘dual-use’ were born and developed, and the other one is a new emerging technology, which is synthetic biology. The aim is to understand how the freedom of scientific research could be shaped in relationship with other rights/needs/interests for dealing with ‘dual-use’ issues in the aforementioned areas of science and technology.

Well-validated reference values are necessary for a correct interpretation of a serum PTH concentration. Establishing PTH reference values needs recruiting a large reference population. Exclusion criteria for this population can be defined as any situation possibly inducing an increase or a decrease in PTH concentration. As recommended in the recent guidelines on the diagnosis and management of asymptomatic primary hyperparathyroidism, PTH reference values should be established in vitamin D-replete subjects with a normal renal function with possible stratification according to various factors such as age, gender, menopausal status, body mass index, and race. A consensus about analytical/pre-analytical aspects of PTH measurement is also needed with special emphasis on the nature of the sample (plasma or serum), the time and the fasting/non-fasting status of the blood sample. Our opinion is that blood sample for PTH measurement should be obtained in the morning after an overnight fast. Furthermore, despite longer stability of the PTH molecule in EDTA plasma, we prefer serum as it allows to measure calcium, a prerequisite for a correct interpretation of a PTH concentration, on the same sample. Once a consensus is reached, we believe an important international multicentre work should be performed to recruit a very extensive reference population of apparently healthy vitamin D-replete subjects with a normal renal function in order to establish the PTH normative data. Due to the huge inter-method variability in PTH measurement, a sufficient quantity of blood sample should be obtained to allow measurement with as many PTH kits as possible. [less ▲]

In this paper, I study the workers’ speeches (“Reden and Rufe”) in the 19th-Dynasty tombs of Deir el-Medina and its surroundings. For this period, only three tombs in Deir el-Medina (TT 212, TT 217, and TT 266) and one in the Theban necropolis (TT 16) preserve such texts. The goal of this paper is twofold. First, it aims at showing that, after falling into disuse in elite tombs, workers’ speeches appear in the tombs of craftsmen and the upper middle class, further evidence of the “democratisation” phenomenon during the 19th Dynasty. A wall relief fragment of the craftsman Meryptah from Saqqara (18th-19th Dynasty) indicates that this phenomenon was not restricted to the Theban area. The second goal of this paper is to determine what kind of language is used in 19th-Dynasty workers’ speeches, since this literary genre is sometimes thought to be written in the vernacular. I argue that it is a mimetic language, “à-la-manière-de,” more than an actual colloquial language. Regarding this question, the tombs of Ipuy (TT 217) and Amennakht (TT 266) lead to a dead-end because of their fragmentary state. The tomb of Ramose (TT 212) and the tomb of Panehsy and his wife Tarenu (TT 16), on the other hand, reveal Late Egyptian linguistic features. But, because their owners belong to a lower social class than the elite, it might suggest a reinterpretation of the rules specific to the literary genre of the workers’speeches (possible diastratic/diaphasic variation).

District heating networks (DHN) are generally considered as a convenient, economic and environmental-friendly way to supply heat to a large amount of buildings. Some modelling methods are required to consider the dynamic behaviour of district heating networks to design them correctly, spare the investment costs and limit the heat losses related to the use of a too high operating temperatures. For the same reasons, the DHN control or retrofit of installations also requires the assessment of the DHN dynamic behaviour. To achieve this, the heat transport in DHN, which is one of the key issues in the behaviour of a whole centralized heating system, has to be correctly modelled. Previous work evidenced current limitations of one dimensional finite volume method to model heat transport in pipes and proposed an alternative method considering the thermal losses and the inertia of the pipes. The present contribution intends to experimentally validate this model on a test rig available at the Thermodynamics laboratory of the University of Liège (ULg, Belgium) and on an existing district heating network. For both experimental facilities, the current model shows good agreement between the experimental data and the simulation results for a large range of water velocities. Moreover, it is shown that the thermal inertia of the pipe has a significant influence on the outlet pipe temperature profile. [less ▲]

Cette monographie est issue de ma thèse de doctorat qui constituait la première étude globale de la modalité en néo-égyptien. Le chapitre introductif [§1] est consacré à la définition du corpus néo-égyptien et intègre une discussion des différentes formes de variation (diachronique, diatopique, diaphasique et diastratique) au sein du corpus néo-égyptien. Cet effort définitoire conforte l’assise empirique de l’étude : la ventilation du corpus en fonction de critères chronologiques et géographiques, de la nature du support et des genres littéraires permet d’objectiver les analyses proposées pour chaque expression de la modalité. Le corps du travail se divise en trois parties consacrées, respectivement, [§2] à une définition générale de la notion de modalité (devant permettre de déterminer les media expressifs qui relèvent de son étude en néo-égyptien) ainsi qu’à l’établissement d’un modèle sémantique de cette notion qui réponde aux impératifs d’économie ainsi que de cohérence et qui rende justice aux données typologiques ; [§3] à l’étude des modalités radicales (i.e. les modalités déontiques et bouliques), en envisageant les relations qu’elles entretiennent avec le domaine axiologique ; [§4] à l’examen des modalités assertives ([§4.a] analyse des formes de complémentation, en ce compris les liens entre intégration syntaxique, variation de l’assertivité et degrés de manipulation ; [§4.b] étude de l’impact des auxiliaires d’énonciation sur le degré d’assertivité d’une proposition ; [§4.c] critique des théories existantes concernant les moyens expressifs du discours indirect en néo-égyptien). Les conclusions [§5] sont accompagnées de propositions prospectives devant permettre [§5.a] de rendre le modèle défendu applicable pour l’étude des complexes conditionnels, [§5.b] d’intégrer la dimension énonciative dans l’analyse des relations interpersonnelles, [§5.c] de décrire adéquatement les expressions de la causalité et de la finalité.

In cold rolling of thin metal strip, contact conditions between the work rolls and the strip are of great importance: roll deformations and their effect on strip thickness variation may lead to strip flatness defects and thickness inhomogeneity. To control the process, several online measurements are usually carried out such as the rolling load, forward slip and strip tensions at each stand. Shape defects of the strip are usually evaluated after the last stand of a rolling mill thanks to a flatness measuring roll. However, none of these measurements is made within the roll bite itself due to the harsh conditions taking place in that area. This paper presents a sensor capable of monitoring roll deformations as well as roll radial stresses in situ and in real time. The sensor emits ultrasonic pulses that reflect from the roll surface. The time-of-flight (ToF) of the pulses is recorded during the testing. The sensor system was incorporated into a work roll and tested on a pilot rolling mill. Measurements were taken as steel strips were rolled under different strip elongation. Roll deformation and radial stresses obtained from the experimental data are in good agreement with numerical results computed with a cold rolling model developed in non-linear Finite Element software.

La problématique du passage de l’administration fixe (de type papier-crayon) à une administration adaptative d’un test est étudiée. Une méthode en deux étapes est présentée. Dans un premier temps, des patrons de réponses sont générés selon une administration fixe, dans le but de déterminer des valeurs admissibles de l’erreur-type d’estimation du niveau d’habileté. Ensuite, ces valeurs sont utilisées comme critères d’arrêt lors d’une administration adaptative du même test. La longueur du test est alors considérée pour évaluer la qualité du test par rapport à sa version fixe. Le test de classement en anglais, langue seconde, au collégial (TCALS-II) est utilisé en guise d’illustration. Il est établi qu’une administration adaptative du TCALS-II permettrait de réduire sensiblement la longueur du test, sans perte de qualité de l’estimation des niveaux d’habileté. Toutefois, cette amélioration est limitée aux sujets ne présentant pas un niveau d’habileté trop faible ou trop important. [less ▲]
