Diagnostic technologies for neuroblastoma
No full textNeuroblastoma is an aggressive childhood cancer characterised by high relapse rates and heterogenicity. Current medical diagnostic methods involve an array of techniques, from blood tests to tumour biopsies. This process is associated with long-term physical and psychological trauma. Moreover, current technologies do not identify neuroblastoma at an early stage while tumours are easily resectable. In recent decades, many advancements have been made for neuroblastoma diagnosis, including liquid biopsy platforms, radiomics, artificial intelligence (AI) integration and biosensor technologies. These innovations support the trend towards rapid, non-invasive and cost-effective diagnostic methods which can be utilised for accurate risk stratification. Point-of-care (POC) diagnostic devices enable rapid and accurate detection of disease biomarkers and can be performed at the location of the patient. Whilst POC diagnostics has been well-researched within the oncological landscape, few devices have been reported for neuroblastoma, and these remain in the early research phase and as such are limited by lack of clinical validation. Recent research has revealed several potential biomarkers which have great translational potential for POC diagnosis, including proteomic, metabolic and epigenetic markers such as MYCN amplification and microRNAs (miRNAs). Using POC devices to detect high-risk biomarkers in biofluids such as blood and urine, offers a non-invasive approach to diagnosis of neuroblastoma, enabling early screening at a population level as well as real-time health monitoring at home. This is critical to mitigating long-term morbidity associated with late diagnosis and unnecessary treatment, in turn improving outcomes for neuroblastoma patients.</p

Parameterization of the Effect of Bench Terraces on Runoff and Sediment Yield by Swat Modeling in a Small Semi‐arid Watershed in Northern Tunisia
No full textIn Tunisia, soil and water conservation interventions are among the most practicable strategies to prevent and mitigate rainwater losses through surface runoff and consequential erosion of fertile soils. In this study, a small and terraced agricultural catchment (Sbaihia) was used as an experimental site to analyze and parameterize the effects of bench terraces on water and sediment yield using the Soil and Water Assessment Tool. Model calibration and validation was performed, taking advantage from high-quality daily runoff data from 1994 to 2000 and a high-resolution bathymetric survey of the hill lake at the watershed outlet. Soil and Water Assessment Tool indicated that the local terraces, established on approximately 50% of the watershed area, reduced surface runoff by around 19% and sediment yield by around 22%, decelerating the siltation of the hill lake. Targeted model calibration delivered concise parameter set describing bench terrace impacts on runoff (Soil Conservation Service curve number method) and sediment yield (Modified Universal Soil Loss Equation) crucial for outscaling of soil and water conservation impacts and suitable watershed management
New Computational Model Based on Finite Element Method to Quantify Damage Evolution Due to External Sulfate Attack on Self-Compacting Concretes
No full textAbstract: This work combines experimental and numerical investigations to study the mechanical degradation of self-compacting concrete under accelerated aging conditions. Four different experimental treatments are tested among them constant immersion and immersion-drying protocols allow an efficient external sulfate attack of the material. Significant damage is observed due to interfacial ettringite. A predictive analysis is then adopted to quantify the relationship between ettringite growth and mechanical damage evolution during aging. Typical 3D microstructures representing the cement paste-aggregate structures are generated using Monte Carlo scheme. These images are converted into a finite element model to predict the mechanical performance under different criteria of damage kinetics. The effect of ettringite is then associated to the development of an interphase of lower mechanical properties. Our results show that the observed time evolution of Young's modulus is best described by a linear increase of the interphase content. Our model results indicate also that the interphase regions grow at maximum stress regions rather than exclusively at interfaces. Finally, constant immersion predicts a rate of damage growth five times lower than that of immersion-drying protocol. © 2012 Computer-Aided Civil and Infrastructure Engineering
Effet de l'attaque sulfatique externe sur la durabilité des bétons autoplaçants
No full textThe aim of the presented research in this thesis focuses on the effect of external sulfate attack on the durability of self-compacting concrete. For that, four types of concretes based on Aigerian cement, crushed aggregates and plasticizers have been made. Each type of concrete has undergone four different protocols of external sulfate attack which are the total immersion, the immersion 1drying at 105 CC, the immersion 1drying at 60 CC and the exposure of specimens to a salt spray. These environments are designed to reproduce the different accelerated sources of pollution that can generate external sulfate attack. A term of six months of exposure of the samples in concrete and mortar, it was possible to draw the main conclusions based on macroscopic and microscopie studies of the sam pies tested. Three different behaviors of concrete have been distinguished: concrete resistant to external sulfate attack, concrete damaged after tis attack and concrete damaged by salt precipitation and not by external sulfate reaction.Les bétons autoplaçants (BAP) se distinguent des bétons ordinaires (BO) ou vibrés, par leurs propriétés à l’état frais. Ils sont capables de s’écouler sous leur propre poids, quelque soit le confinement du milieu, et restent homogènes au cours de l’écoulement. Pour parvenir à ce cahier de charge, les BAP sont formulés différemment des BO. En général, ils possèdent un même dosage en ciment et en eau que les BO ainsi qu’un volume de sable assez proche. L’apport de la pâte (ciment + eau + adition) est privilégié au détriment des gravillons. L’objectif du travail de recherche présenté dans cette thèse porte sur l’effet de l’attaque sulfatique externe sur les bétons autoplaçants. Pour cela quatre types de bétons autoplaçants à base de ciments, de granulats concassés et d’adjuvants ont été confectionnés. Chaque béton a subit quatre protocoles différents d’attaque sulfatique externe à savoir l’immersion totale, l’immersion-séchage à 105°C, l’immersion-séchage à 60°C et l’exposition des éprouvettes à un brouillard salin. Ces ambiances visent à reproduire de manière accélérée les différentes sources de pollutions capables de générer des attaques sulfatiques externes. A terme de six mois d’exposition des échantillons en béton et en mortier, il a été possible de dresser les principales conclusions reposant sur des études macroscopiques et microscopiques des échantillons testés. Trois comportements différents des bétons ont pu êtres distingués : bétons résistent à l’attaque sulfatique externe, bétons endommagés suite à cette attaque et bétons endommagés par la précipitation des sels et non par une réaction sulfatique externe. En conclusion, cette recherche a permis d’identifier les protocoles accélérés les plus adaptés aux études de la durabilité des bétons et de classer les bétons autoplaçants confectionnés avec des granulats concassés selon leurs résistants aux attaques sulfatiques externes (pollutions industrielles ou construction sur des sols gypseux)

Entretien avec Mohamed Miloud Gharrafi
No full textMohamed Miloud Gharrafi, auteur de plusieurs recueils de poèmes en arabe, a signé, en 2014, une anthologie bilingue de ses poèmes autotraduits, augmentée d’inédits, intitulée Échos lointains. Il a accepté de s’entretenir avec nous sur sa pratique d’écrivain et de traducteur, et de présenter sa vision de l’acte de traduction et de ses relations avec la création, aussi bien dans le cas de l’autotraduction que dans celui de la traduction d’autres poètes, dont il a fait l’expérience à plusieurs reprises. Cette réflexion l’amène à poser la question des liens complexes, dans la poésie et sa traduction, entre la forme et le sens. Elle l’amène également à décrire son rapport, à la fois de filiation et de rupture, avec la tradition poétique arabe, ainsi que ses appartenances multiples à divers univers culturels et littéraires.Mohamed Miloud Gharrafi, author of several collections of poems in Arabic, signed a bilingual anthology of his self-translated poems in 2014, supplemented by unpublished ones, entitled Échos lointains.
