description: The accurate quantification of blood flow in aortoiliac arteries is challenging but clinically relevant because local flow patterns can influence atherosclerotic disease. To investigate the feasibility and clinical application of two-dimensional blood flow quantification using high-frame-rate contrast-enhanced US (HFR-CEUS) and particle image velocimetry (PIV), or US velocimetry, in participants with aortoiliac stenosis. In this prospective study, participants with a recently diagnosed aortoiliac stenosis underwent HFR-CEUS measurements of the pre- and poststenotic vessel segments. Two-dimensional quantification of blood flow was achieved by performing PIV analysis, which was based on pairwise cross-correlation of the HFR-CEUS images. Visual inspection of the entire data set was performed by five observers to evaluate the ability of the technique to enable adequate visualization of blood flow. The contrast-to-background ratio and average vector correlation were calculated. In two participants who showed flow disturbances, the flow complexity and vorticity were calculated. Results: 35 participants were included. Visual scoring showed that flow quantification was achieved in 41 of 42 locations. In 25 locations, one or multiple issues occurred that limited optimal flow quantification, including loss of correlation during systole, shadow regions, a short vessel segment in the image plane, and loss of contrast during diastole. In the remaining 16 locations, optimal quantification was achieved. The contrast-to-background ratio was higher during systole than during diastole, whereas the vector correlation was lower. Flow complexity and vorticity were high in regions with disturbed flow. Blood flow quantification with US velocimetry is feasible in patients with an aortoiliac stenosis, but several challenges must be overcome before implementation into clinical practice.
Geochemistry of shield basalts from Kaua‘i, Hawai‘i : exploring the emergence of the Hawaiian geochemical trends
Creators: name: Williamson, Nicole
Publisher: name: University of British Columbia
Year: 2023

description: Ocean island basalts are indirect records of Earth’s mantle chemistry and are fundamental for constraining its evolution through geological time. Volcanoes of the ~6000 km-long Hawaiian-Emperor chain represent an extraordinary record of Pacific mantle chemistry over the past ~80 Ma, formed as the Pacific tectonic plate passed over the deeply sourced Hawaiian mantle plume. Hawaiian volcanoes are divided into southwestern (Loa) and northeastern (Kea) geographic and geochemical trends that reflect the chemical structure of the underlying plume and its deep mantle sources. This dissertation addresses a change in the chemistry of erupted lavas between the Northwest Hawaiian Ridge and the younger Hawaiian volcanoes using a new database from the northernmost island of Kaua‘i that includes high-precision radiogenic isotopes (Pb, Sr, Nd, Hf), major element oxides, trace element concentrations, and ⁴⁰Ar/³⁹Ar geochronology. Western and eastern Kaua‘i erupted at different times and from distinct mantle sources. The distribution of Loa and Kea compositions on Kaua‘i is opposite to the younger Hawaiian Islands and is explained by a more westward trend of plate motion relative to the Loa- Kea compositional boundary in the plume. Loa compositions dominated the geochemistry of erupted lavas for over 2 Ma before the onset of the bilateral Loa and Kea geochemical trends. Loa compositions are isotopically enriched and may be influenced by subducted materials recycled in the deep mantle source of the Hawaiian plume that were stored within the thermally and chemically distinct Pacific large low shear wave velocity province (LLSVP). Thallium isotopes were used to test whether these materials originally consisted of pelagic sediment and were measured in 33 samples from the entire geochemical range of Hawaiian lavas. Results show evidence of recycled materials on the Kea side of the plume, implying that the lower mantle is heterogeneous both within and outside of the LLSVP. This dissertation provides important insight into the timing and source of two major geochemical components along the most active hotspot system on Earth and expands our knowledge on the chemical structure of the Hawaiian plume, its evolution in space and time, and the nature of its deep mantle sources.

description: L'impression 3D du béton par extrusion/dépôt est un processus complexe en plusieurs étapes qui doit être bien décrit et optimisé. Les propriétés des matériaux cimentaires à l’état frais (et leurs évolutions) doivent être optimisées aussi bien pour l'extrusion que pour les procédés d'impression 3D. Par conséquent, les matériaux doivent présenter des propriétés spécifiques telles que la stabilité pendant l'extrusion, la stabilité de la forme lorsque le matériau coule de l'extrudeuse, le jointoiement entre les couches et un raidissement rapide afin de supporter le poids des couches subséquentes. Ces propriétés spécifiques du procédé doivent être décrites en termes de propriétés intrinsèques des matériaux telles que la perméabilité, la viscosité, la contrainte seuil et la vitesse de structuration afin de saisir la physique sous-jacente. Par exemple, la vitesse de structuration sera utile afin de minimiser l'intervalle de temps entre deux placements superposés consécutifs. Ce travail vise à décrire le lien entre les caractéristiques intrinsèques des matériaux et la technique d'impression 3D par extrusion afin d'optimiser la méthode de traitement.

description: L’utilisation des matériaux à changement de phase comme substitut au agrégat fins est d’un intérêt grandissant dans l’industrie de la construction. Cependant l’intégration des matériaux à changement de phase dans les matrices cimentaires peut entrainer de sévères dégradations de leurs caractéristiques mécaniques. Dans la présente étude, un mortier modifié intégrant différent taux de mcp (5wt %, 10wt%, 15wt %) a été préparé. Des tests de résistance à la compression et de flexion ont été effectués sur les différents composites à des températures inferieurs et supérieur à la température de changement de phase (≈25°). Les différentes matrices mortier –mcp ont été renforcées par 3 couches de textile verre Alkali résistant. Les composites TRCMCP ont été testés en traction suivant les recommandations du Rilem [1]. Il a pu être conclu que le renfort textile peut scientifiquement améliorer les performances mécaniques en traction des matrices en mortier –mcp, cependant un taux critique de mcp (≈15wt%) existe et peut entrainer une rupture soudaine par délaminage entre les différentes couches de renfort.

description: The increasing use of teams within organizational contexts has led to a significant stream of literature examining the impact and consequences of intra-group conflicts on team outcomes. The purpose of this review is to identify and analyze process factors and emergent states in conflict research in terms of their impact on the relationship between conflict types (task, relationship, process and interest-based) and team effectiveness. A systematic literature search was conducted resulting in 182 articles included in the second screening. The preliminary results indicate different process factors and emergent states like conflict management styles and team cohesion. The results of the review give an overview of the process variables in conflicts and can be used to identify key factors for managing conflicts within teams. Furthermore, it can guide the development of interventions and training programs.

description: Ce travail s’inscrit dans le cadre du projet national à Fond Unique Interministériel, nommé ERGOFORM (ERGOnomic FORMwork - Système de coffrage auto-stable diminuant la pénibilité de chantier), qui vise à mettre au point un procédé de coffrage innovant. Quatre pâtes de ciment ont été élaborées avec des rapports Eau sur Ciment (E/C) de respectivement 0,30, 0,35, 0,40 et 0,45. L’évolution des propriétés physiques et mécaniques des pâtes de ciment ont été mesurées : la porosité accessible à l’eau sous vide, les résistances à la compression et en flexion trois points. L’évolution des paramètres de rugosité en fonction du temps de cure a été analysée par microscopie interférométrique et microscopie électronique à balayage environnemental (MEB-E). Les résultats expérimentaux montrent que l’augmentation du dosage en ciment diminue la porosité accessible à l’eau et améliore les propriétés mécaniques à 24h (après décoffrage nommé T0). L’évolution de la porosité en fonction du temps de cure montre une augmentation se stabilisant après 4 jours d’immersion dans l’eau pour les pâtes cimentaires de rapports E/C de 0,40 et de 0,45 (Groupe 2). En revanche, cette augmentation se prolonge légèrement pour les pâtes de ciment 0,30 et 0,35 (Groupe 1). Par ailleurs, l’évolution des paramètres de rugosité est fonction du dosage en ciment. En effet, les analyses microscopiques et par diffraction des rayons X mettent en évidence une diminution de la quantité des pores en surface, mais aussi l’évolution des paramètres de rugosité par un changement de sa morphologie et la formation de portlandite même après 2 heures de cure normalisée.

description: The dynamics of chiral nuclei is investigated for the first time with the time-dependent and tilted axis cranking covariant density functional theories on a three-dimensional space lattice in a microscopic and self-consistent way. The experimental energies of the two pairs of the chiral doublet bands in $^{135}$Nd are well reproduced without any adjustable parameters beyond the well-defined density functional. A novel mechanism, i.e., chiral precession, is revealed from the microscopic dynamics of the total angular momentum in the body-fixed frame, whose harmonicity is associated with a transition from the planar into aplanar rotations with the increasing spin. This provides a fully microscopic and dynamical view to understand the chiral excitations in nuclei.

Framer Framed in "A Tendency to Forget"

Publisher: name: artciencia.com, Revista de Arte, Ciência e Comunicação
Year: 2017

description: Evoking Trinh T. Min-ha’s book tittle, this paper focuses on how, in the artwork ‘A tendency to forget’ Ângela Ferreira reverses the gaze, transforming the ethnographic work of Jorge and Margot Dias into her research study. Not completely acritical to Anthropology and its primitivisms, modern Ethnography as seen by Clifford and its methodologies seemed increasingly suitable to artists after the 1960’s to work and respond to the fragmented world, and participant observation, fieldwork and the archive were adopted as methodological tools to experience, interpret and represent different cultures. The archival impulse has become central to many contemporary art practices since the 1980’s and the retrieval of lost historical information and the will to establish links between different events are some of the strands of this practice as defined by Foster in his seminal essay. For the critic Mark Godfrey the working with ruins and fragments of the past and the appropriation of the archive are important research tools for the 'artists as historians' who, through their work, propose an ' alternative ' knowledge of history. Intrigued by the absence of a critical discourse about the country’s colonial past, but at the same time conscious of the need to question the histories and representations of the past in order to get a different understanding of the present, the artist Ângela Ferreira has consistently engaged with episodes of Portuguese Colonial history to point to its lacunae or inconsistencies. The work ‘A tendency to forget’ is part of her practice based PhD research, in which by focusing on the Dias’, the artist points to the hidden political agenda of their ethnographic fieldwork in Mozambique, in an invitation to think about the past, to establish connections between events, characters and objects and to assemble these into an ‘alternative’ narrative of the colonial past and memory, different from the version disseminated in the wider cultural field.

description: En discutant avec mes collègues à la salle des maîtres, j’ai remarqué que les rencontres entre parents et enseignante semblaient susciter chez tout le monde de vives réactions. Pour la plupart comme pour moi-même, rencontrer les parents paraît être un moment particulièrement stressant. Je me suis donc intéressée à ce qui pouvait transformer une simple interaction en une « épreuve » aussi préoccupante. Pour interpréter ce phénomène, huit enseignantes du cycles 1 et 2 ont participé à un entretien afin de répondre à mes questions. Il a donc en premier lieu été question de s’intéresser aux perceptions de chacun des acteurs de l’interaction dans le cadre théorique. Il s’agissait de mettre en avant la relation qui les unit, dans le but de comprendre les raisons qui rendent nécessaires ces rencontres. Par la suite, la recherche a permis de démontrer que les enseignantes appréhendent le fait d’être confrontées par les parents, mais également l’idée de devoir leur annoncer que leur enfant rencontre des difficultés scolaires. Cependant, la majorité des entretiens servent à annoncer ce genre de bilan. Les enseignantes redouteraient particulièrement cette étape, car elles savent que les parents sont susceptibles de se « braquer » et d’aller à l’encontre de ce qu’elles préconisent. Si tel est le cas, elles doivent alors s’affairer dans un grand travail de conviction dans le but de voir les parents finir par accepter la situation et les démarches qui en résultent. Ce travail de conviction peut prendre des mesures exceptionnelles, au point que l’on pourrait se demander s’il n’est pas finalement question d’imposer une solution au détriment de la relation « partenariale » initialement souhaitée. Dès lors, il paraît plus évident que les rencontres entre enseignante et parents n’ont plus rien de quelconque et qu’elles suscitent une telle préoccupation.
Etude d’impact de la forme des granulats sur les paramètres du modèle d’empilement compressible

description: Le béton hydraulique est, depuis son invention, le matériau de construction le plus utilisé au monde. Parmi ses constituants, les granulats occupent jusqu’à 75% du volume. Le volume restant étant constitué d’une pâte de ciment, cela engendre des quantités de ciment colossales et un bilan carbone lourd. Les mélanges granulaires incorporés dans le béton peuvent se présenter sous une forme dense (cas d’un Béton à Haute Performance) à lâche. Des études récentes sur la compacité des granulats [1] ont conduit au développement du modèle d’empilement compressible (MEC) qui permet de calculer la compacité d’un mélange de deux ou plusieurs fractions granulaires à partir des compacités individuelles de ces fractions. L’optimisation de la compacité des mélanges granulaires permet non seulement de minimiser la quantité de ciment incorporée dans le béton, mais aussi d’améliorer sa performance et sa durabilité.

description: This architectural thesis can be understood as the report of an exploration of sustainability, participation and the building life cycle. Against the background of changing societies and our planet’s changing climate, the project presented deals with the various aspects of sustainability, and tries to envision a democratic and sustainable design process supported by technology. To identify the goal and purpose for the project, a participatory design process with a co-housing group in Austria was performed to detect the group’s common vision and requirements towards a residential project. Through several workshops these were elaborated and shaped into first conceptual designs. To assess and improve the environmental performance of these concepts and support fact-based design decisions, a variety of scenarios for building materialisation, energy standard and energy supply mix were compared using the method of Life Cycle Assessment (LCA). Working towards the integration of LCA into the architectural design and planning process, a prototypical workflow to combine LCA with the planning method of Building Information Modelling (BIM) was developed. Through the application of visual scripting, essential steps of LCA could be integrated into a BIM workflow and novel methods of communicating assessment results using the digital building model could be shown.
The targum (1936:Dec. 5 - 1936:Dec. 16)
Creators: name: No Name Supplied
Publisher: name: Targum Association
Year: 1936

description: Some University historians indicate that the Targum was first published as an annual in 1867, but of this we have no extant evidence. In January 1869, the Targum as we now know it, made its appearance as a monthly paper that concerned itself with student “literary contributions” and college news as well as serving as a vehicle for bringing news to alumni and the general public. The newspaper, which originally was for sale, varied in frequency over the years as did its title (The Targum, Rutgers Targum, Rutgers Daily Targum, and Daily Targum). The newspaper has continuously been published since 1869 with the exception of 19 months during the second world war, between February 1944 and October 1945. The Targum was published by the students of Rutgers College, and later Rutgers University—New Brunswick represented through the years as the Targum Association, Rutgers Targum Association, and Rutgers College Targum. As a student organization, the Targum operated under the oversight of the dean of students and student government but in October 1980, the Targum became an independent college paper.

description: Les sols latéritiques sont les matériaux les plus répandus dans les régions tropicales et utilisés en technique routière pour la réalisation des assisses de chaussées. Cependant, dans de nombreux pays, la qualité des routes et pistes latéritiques laisse à désirer. Ce niveau de qualité peut s’expliquer par des problèmes de mise en œuvre mais également par des insuffisances des méthodes de conception. En effet, la démarche actuelle de dimensionnement s’opère par le choix de structures de chaussées en fonction de la classe de trafic et de portance du sol caractérisée par l’indice CBR. La validation de ces structures est effectuée à l’aide de modèles numériques nécessitant l’utilisation de module élastique en donnée d’entrée. Cette donnée est obtenue le plus souvent par des corrélations empiriques avec l’indice de portance CBR proposé par le guide CEBTP. L’objectif de cette étude est de comprendre les insuffisances de cette démarche et de proposer une approche permettant d’améliorer la corrélation entre les mesures des caractéristiques in situ de ces matériaux et leurs caractéristiques mécaniques (module et indice CBR).

description: Users around the world rely on software-intensive systems in their day-to-day activities. These systems regularly contain bugs and security vulnerabilities. To facilitate bug fixing, data-driven models of automatic program repair use pairs of buggy and fixed code to learn transformations that fix errors in code. However, automatic repair of security vulnerabilities remains under-explored. In this work, we propose ways to improve code representations for vulnerability repair from three perspectives: input data type, data-driven models, and downstream tasks. The expected results of this work are improved code representations for automatic program repair and, specifically, fixing security vulnerabilities.

description: Molluscs forage with their radula, a chitinous membrane with teeth. Adaptations to hard or abrasive ingesta were well studied in Polyplacophora and Patellogastropoda, but for other taxa there are large gaps in knowledge. Here, we investigated the nudibranch gastropods Felimare picta and Doris pseudoargus, both of which feed on Porifera. Tooth morphologies were documented by scanning electron microscopy and mechanical properties were tested by nanoindentation. We found that these parameters are rather similar in both species, indicating that teeth are similar in their function. To study the composition, teeth were visualized using confocal laser scanning microscopy (CLSM), to determine the degree of tanning, and analysed with energy-dispersive X-ray spectroscopy, to test the elemental composition. The emitted autofluorescence signal and the inorganic content differed between the species. This was especially prominent when studying the inner and outer tooth surfaces (leading and trailing edges). In F. picta, we detected high proportions of Si, whereas teeth of D. pseudoargus contained high amounts of Ca, which influenced the autofluorescence signal in CLSM. Employing nanoindentation, we determined high Young's modulus and hardness values for the leading edges of teeth, which relate to the Si and Ca content. This highlights that teeth with a similar morphology and mechanical properties can be mechanically enhanced via different chemical pathways in Nudibranchia.
title: Using Existing School Messaging Platforms to Inform Parents about Their Child’s Attendance

description: School attendance is strongly associated with academic success and high school completion, but
approximately one in seven students miss nearly one month of school each year. To address chronic
absenteeism, we partnered with four public school districts in the metro Atlanta area and experimentally
deployed email and text messages to inform parents about their child’s attendance. Parents received
personalized monthly messages through the school districts’ existing messaging platforms that have zero
marginal cost per message. The messages informed parents about their child’s number of absences and
how that number compares to the absences of their peers (in percentile terms). We find that receiving
these messages reduced end-of-year absences by almost one day (5 percent) and reduced the probability
of chronic absenteeism by 7.8 percent. However, we also find that parents of students most in need of
improved attendance were the hardest to reach.
Control of cascading failures in dynamical models of power grids

Subjects: subject: Systems and Control (eess.SY)

description: In this paper, we introduce a distributed control strategy to prevent dynamically-induced cascading failures in power grids. We model power grids using complex networks and nonlinear dynamics to provide a coarse-grained description of the electro-mechanical phenomena taking place on them (in particular, we use coupled swing equations) and restrict our analysis to cascades of line failures, i.e., failures due to power flows exceeding the maximum capacity of a line. We formulate a distributed control protocol relying on the same topology of the physical layer and apply it to several power grid models, including a small-size illustrative example with five nodes, the Italian high-voltage (380kV) power grid, and the IEEE 118-bus system. Our results indicate that the approach is capable of preventing cascading failures, either controlling each node of the network or a suitable subset of them.

description: This paper proposes an augmented speed control scheme of dual induction motors fed by a five-leg voltage source inverter (VSI) with a common/shared-leg. An additional control loop is proposed here and based on the mutual flux angle – the difference between flux angular positions of the IMs. The main purpose of this research is to minimize the energy losses in the common inverter leg by controlling the mutual flux angle, at equal angular speeds of both motors. Simulation and experimental studies were carried out and the effectiveness of the proposed control method was proven. The PLECS software package was used for the simulation tests. The laboratory prototype was prepared for the experimental validation. All results were provided and discussed in this paper.

Ce travail est réalisé dans le cadre du projet ECO-TERRA R&D en collaboration avec quatre laboratoires de recherches français, des producteurs de chanvre en circuit-court et des artisans spécialisés dans l’utilisation de la terre et du chanvre en construction. Ce document se concentre premièrement sur deux démarches d’observation de la variabilité : une méthode qualitative et visuelle par la réalisation d’une matrice de consistance, et une méthode quantitative par la réalisation d’essais géotechniques. Les résultats de ces essais permettent ensuite une compréhension de la mesure du seuil de cisaillement sur chantier, ainsi que sa comparaison avec une mesure de laboratoire.

description: Cet article présente une étude expérimentale des propriétés chimiques et mécaniques de l’interphase pâte de ciment / granulat. La zone d’interphase est la zone de la pâte de ciment qui se trouve à proximité immédiate du granulat sur une épaisseur d’environ 20 – 50 μm et qui possède des propriétés mécaniques et chimiques différentes de celles de la pâte de ciment pure. Des échantillons composites pâte de ciment / granulat calcaire ont été conçus et préparés afin de permettre l’étude des propriétés chimiques et mécaniques de l’interphase. La pâte de ciment est réalisée à base de ciment Portland avec un rapport E/C de 0,4. Les profils de concentration en Calcium réalisés autour la zone de l’interphase montrent une forte concentration en calcium due à la présence de la portlandite. Les essais de nano-indentation indiquent une zone de faiblesse au niveau de l’interphase.

A novel factor-dependent internal ribosome entry site and programmed frameshifting signal in the Bemisia-associated dicistrovirus 2

description: Internal ribosome entry sites (IRES) are structured RNA elements that recruit ribosomes using a subset of translation factors in a 5' cap-independent manner. The dicistrovirus IRES uses the most streamlined mechanism: the IRES recruits ribosomes directly without the use of initiation factors and directs translation from a non-AUG codon. The IRES adopts three pseudoknots, stem-loop, and unpaired regions that interact with specific domains of the ribosomal 40S and 60S subunits. Analysis of dicistrovirus-like genomes identified via metagenomic studies predicts potentially novel atypical IRES RNA structures. Specifically, the Bemisia-associated dicistrovirus 2 (BaDV-2) IRES contains an unusual RNA structure that lacks conserved elements and altered structures that do not conform to the typical dicistrovirus IRES mechanism. Moreover, the BaDV-2 genome contains a predicted -1 frameshifting signal (FSS) with an RNA stem-loop structure that would direct the translation of the RNA-dependent RNA polymerase (RdRp) motif. In this study, using a bicistronic reporter, we demonstrate that BaDV-2 IGR supports internal ribosome entry activity in in vitro insect Sf-21 and rabbit reticulocyte translation extracts. Using deletion and mutagenesis analyses, we showed that the BaDV-2 IRES activity is within a minimal 140 nucleotide element containing a predicted stem loop. Moreover, the IRES is sensitive to eIF2 and eIF4A inhibitors, NSC1198983 and hippuristanol, respectively, indicating that the BaDV-2 IRES is factor-dependent, unlike typical factor-less dicistrovirus IRESs. Preliminary data shows that a chimeric dicistrovirus infectious clone does not support virus infection in Drosophila cells. Finally, we show that the predicted stem-loop structure -1 frameshifting signal can direct programmed frameshifting in vitro using a luciferase-based bicistronic reporter. In summary, we have provided evidence of the first -1 frameshifting signal and a novel IRES mechanism in this viral family, thus highlighting the diversity of viral strategies to direct viral protein synthesis.
Cinema and Architectural Design Education

description: This research focuses on revealing the contribution of cinema movies to understanding design ideas and stimulating student cooperation in architectural design education procedure. The topic is based on the use of cinema films as a methodological tool in architectural design education leading to the comprehension of the meaning in space production and architectural design. It is suggested that the film’s “truth” coincides with the designer’s “truth” as they are both subjective and are communicated to their potential viewers or users. They both use visual and functional qualities for creating spaces that do not pre-exist. Through these paths and similarities, it can be argued that the cinema image can alter and enrich the vision of a designer.

description: Ce travail a pour but de comparer, pour une même classe de résistance mécanique (entre 47 et 52 MPa), des mortiers géopolymères à base de laitier de haut fourneau et de métakaolin avec un mortier Portland. A l’issu d’une étude préliminaire, un mortier normalisé de référence, formulé avec un ciment Portland (CEM II 42,5), ainsi que trois mortiers géopolymères ont été développés et caractérisés aux états frais et durci. La rhéologie, le temps de prise, les résistances mécaniques et le module d’élasticité dynamique ont été évalués pour chaque matériau conformément aux normes des mortiers cimentaires. Les résultats obtenus montrent qu’en termes de résistances mécaniques, les mortiers géopolymères à base d’un rapport laitier/métakaolin de 50/50 sont comparables au mortier de référence. Par ailleurs, leur temps de prise est deux fois plus rapide par rapport au mortier Portland alors que leur rigidité est 40% moins importante.

description: Les agrégats d’enrobés proviennent de la démolition des couches bitumineuses des chaussées routières et sont recyclés soit dans des enrobés chauds, soit dans des enrobés tièdes. Le projet ORRAP (Optimal Recycling of Reclaimed Asphalts in low traffic Pavements) s’intéresse au recyclage à froid des agrégats d’enrobés dans les couches d’assise des chaussées à faible trafic. Etablir les conditions requises pour leur réemploi dans les chaussées à faible trafic est l’un des principaux objectifs de ce projet, sachant que ces chaussées représentent 70% du réseau national français. D’un point de vue expérimental, l’effet de la température sur le comportement mécanique est un élément clé. En effet, l’enrobage de l’agrégat rend le matériau sensible à la température. Dans un premier temps, les conditions d’échantillonnage sont étudiées. Puis, ces matériaux granulaires cohésifs sont soumis à des essais de rupture, des essais triaxiaux à chargements répétés et à différentes températures (entre 20 et 50 degrés). Les comportements réversible et irréversible des échantillons seront observés.

description: La détermination du profil hydrique dans le bois au cours du temps permet de comprendre et de prédire les phénomènes liés au séchage, le comportement mécanique du bois, et les risques d’attaques fongiques. En effet ces quelques pourcentages d’eau situés au sein des parois cellulaires vont avoir une forte influence notamment sur les caractéristiques mécaniques de celles-ci. Aujourd’hui l’Eurocode 5 propose un abaque d’équilibre hygroscopique unique, basé sur le séchage de résineux uniquement. Nous proposons de référencer les phénomènes physiques mis en jeu lors du transfert hydrique dans un élément en bois soumis à un environnement variable en humidité et température, afin de d’identifier des propriétés de diffusion des essences de bois. De nouveaux abaques d’équilibre hygroscopique pour les essences de feuillus sont proposés en vue d’une meilleure valorisation de ces derniers dans la construction.

Abstract
Ketoconazole (Ketoconazole HRA™), an imidazole derivative, is a useful treatment option in the management of endogenous Cushing’s syndrome in adults and adolescents > 12 years of age, based on evidence from more than three decades of use of the drug in clinical practice. Originally developed as an antifungal agent, ketoconazole is a potent steroidogenesis inhibitor. Approximately 60% (range, 45–88% across key studies) of patients with Cushing’s syndrome who are treated with ketoconazole achieve control of hypercortisolism, with efficacy demonstrated in all aetiologies of the disease. Furthermore, reductions in cortisol levels in patients treated with ketoconazole are associated with improvements in clinical and biochemical features of Cushing’s syndrome and common comorbidities. Hepatotoxicity, the main safety concern with ketoconazole, can be managed effectively with careful monitoring of hepatic enzymes, with hepatic enzyme abnormalities generally being mild to moderate, asymptomatic and reversible upon dose reduction or drug withdrawal.

Year: 2015

description: O presente artigo procura lançar uma reflexão atenta sobre os persuasive games, videojogos que se distanciam dos padrões habituais fomentados pela própria indústria e que têm vindo a ser cada vez mais utilizados como ferramentas e veículos de comunicação eficazes através de mensagens codificada na sua linguagem e estimuladas através da jogabilidade. Os persuasive games são criados no sentido de fomentar o pensamento crítico de quem os joga. Embora, na sua maioria, resultem em experiências de curta duração, procuram elevar, através de mecânicas na linguagem dos videojogos, o exponencial comunicativo da mensagem gerada pelo conteúdo que apresentam. O seu grande potencial não envolve necessariamente a habilidade de mudar comportamentos mas sim de encorajar os jogadores a considerarem os prós e contras das suas acções. Com isso, acabam por persuadi-los a reflectir sobre si próprios, perante a forma como lidam e jogam a situação representada no jogo.
