Self-adaptive isogeometric discretisations of the second-order forms of the neutron transport equation with dual weighted residual or goal-based error measures
Creators: name: Latimer, Charles
Publisher: name: Imperial College London
Year: 2019

description: In this thesis several second-order forms of the neutron transport equation (NTE) are spatially discretised with isogeometric analysis (IGA). IGA allows for the exact representation of geometries that are produced using computer aided design (CAD) software. Finite element (FE) spatial discretisation methods are incapable of exactly representing all the geometries that are produced by CAD software. Furthermore, the NURBS basis functions allow for high-order continuity within a NURBS patch, whereas FE basis functions are typically C0 continuous between adjacent FEs. The advantages and disadvantages of NURBS based IGA will be investigated by comparisons to FE based spatial discretisations. The second-order forms of the NTE investigated in this thesis are: the self-adjoint angular flux (SAAF) equation, the least-squares (LS) equation, and the weighted least-squares (WLS) equation. The discrete ordinate (SN) method will be used to angularly discretise these equations. A number of verification benchmark problems will be used to determine the numerical accuracy, convergence, and computational efficiency of both the second-order forms of the NTE, and the IGA spatial discretisation method. One major challenge associated with continuous IGA spatial discretisations is performing local refinement of the IGA discretisation. Therefore, a constraint based local adaptive mesh refinement (AMR) algorithm is developed to overcome this challenge. Both heuristic and dual weighted residual (DWR) or goal-based error measures are developed in order to determine where local refinement needs to be performed. The DWR error measures enable the numerical error in both global (Keff) and local (reaction rate) quantities of interest to be determined rigorously. Once again a number of verification benchmark problems are used to analyse the numerical accuracy, convergence and computational efficiency of the IGA AMR algorithm.

description: Au cours de ces dernières années, la capacité de cicatrisation autogène du béton a été étudiée dans diverses conditions qui influencent la quantité et la qualité des produits de cicatrisation. L’addition des liants minéraux permet d’améliorer ce phénomène en favorisant les regains des propriétés mécaniques. Dans cette étude expérimentale, nous avons confronté six formules de mortiers avec des dosages différents en minéraux. Les résultats montrent que le meilleur regain mécanique est attribué au mélange incluant 15% de métakaolin et 15% de laitier en substitution volumique au ciment. L’origine de ce regain a été caractérisée par une observation microscopique au MEB et à l’aide d’un modèle micromécanique.

Making meaning of Laurence Olivier : reading queer sensibilities in his Hollywood performances, 1939-1960

subject: Motion picture acting

description: Between 1939 and 1940, British actor Laurence Olivier broke new ground as a film actor and star in a sequence of landmark performances in classical Hollywood cinema: as a tortured Heathcliff in ‘Wuthering Heights’ (William Wyler, 1939), a brooding Maxim de Winter in ‘Rebecca’ (Alfred Hitchcock, 1940), and a charming Darcy in ‘Pride and Prejudice’ (Robert Z. Leonard, 1940). This thesis argues that Olivier’s performances in these and subsequent Hollywood films depended on not only his much-vaunted abilities as an actor, but, more fundamentally, on an erotically mysterious and ultimately queer masculinity singular among male stars in the classical Hollywood era. It identifies this queerness as crucial to the Hollywood oeuvre Olivier established by these initial, star-making roles, particularly his performances as George Hurstwood in ‘Carrie’ (William Wyler, 1952), the Prince in ‘The Prince and the Showgirl’ (Laurence Olivier, 1957), Gen. Burgoyne in ‘The Devil’s Disciple’ (Guy Hamilton, 1959) and Crassus in ‘Spartacus’ (Stanley Kubrick, 1960). Existing scholarship on Olivier offers a myopic understanding of the actor, as it neglects his other Hollywood projects in favour of his Shakespearean works on stage or screen. Against such neglect, the thesis is comprised of seven case studies, which, taken together, reveal a continuous, if varied, trajectory of a subversive sexual presence central to his Hollywood career. This thesis deploys Eve Kosofsky Sedgwick’s foundational concept of the closet to identify and decode a closetedness in each of Olivier’s performances, to argue for their queer sensibilities. Each case study textually analyses Olivier’s performance by bringing various accounts of gender and desire in dialogue with central concepts in queer theory as well as biographical material and archival resources. In exploring the queerness underlying Olivier’s Hollywood performances, this thesis offers a fundamental reassessment of the cultural, social, and aesthetic impact of a figure central to modern conceptions of acting.
An investigation into the interplay between MutSβ and SLX4 complexes in DNA recombination and repair
Creators: name: Young, Sarah Jane
Publisher: name: Imperial College London
Year: 2019

description: The efficient cleavage of branched DNA intermediates that arise during DNA replication, recombination or repair is essential for the maintenance of genomic stability. Human SLX4 is a scaffold protein for the assembly and activation of three structure selective endonucleases (SSEs) that cleave branched DNA structures - SLX1, MUS81-EME1 and XPF-ERCC1 (collectively known as the SMX complex). These endonucleases have diverse substrate specificities and play multiple individual and combined roles in DNA metabolism. SLX4 interacts with MutSβ (MSH2-MSH3), a heterodimeric ATPase that binds to heteroduplex DNA loops and other branched DNA structures. MutSβ is required for the mismatch repair (MMR) of small loops that arise erroneously during replication. MutSβ also has a pathogenic role in promoting the instability of trinucleotide repeat tracts, a process causative of numerous degenerative disorders such as Huntington’s disease and myotonic dystrophy. However, little is known about the function of SLX4-MutSβ complexes or how they contribute to genomic stability. Here we show that SLX4 interacts with MutSβ in human cells in the absence of exogenous DNA damage. In vitro, purified MutSβ stimulates the SLX1-SLX4 and SMX-mediated cleavage of branched DNA structures similar to those associated with trinucleotide repeat instability and homologous recombination. Moreover, MutSβ is required for the efficient processing of late recombination intermediates in cells to allow accurate sister chromatid separation. We propose that MutSβ is an important component of the SLX4-repair complex, and depending on the DNA context, SLX4-MutSβ interactions can function to either protect genome integrity, or promote genomic instability.

description: Tensile-strained pseudomorphic Ge1–x–ySnxCy was grown on GaAs substrates by molecular beam epitaxy using carbon tetrabromide (CBr4) at low temperatures (171–258 °C). High resolution x-ray diffraction reveals good crystallinity in all samples. Atomic force microscopy showed atomically smooth surfaces with a maximum roughness of 1.9 nm. The presence of the 530.5 cm−1 local vibrational mode of carbon in the Raman spectrum verifies substitutional C incorporation in Ge1–x–ySnxCy samples. X-ray photoelectron spectroscopy confirms carbon bonding with Sn and Ge without evidence of sp2 or sp3 carbon formation. The commonly observed Raman features corresponding to alternative carbon phases were not detected. Furthermore, no Sn droplets were visible in scanning electron microscopy, illustrating the synergy in C and Sn incorporation and the potential of Ge1–x–ySnxCy active regions for silicon-based lasers.
Understanding the interface chemistry of TiO2/Fe2O3 composite photocatalyst-sorbent materials for the treatment of arsenic(III) contaminated waters
Creators: name: Bullen, Jay
Publisher: name: Imperial College London
Year: 2020

description: Over one hundred million people worldwide are exposed to arsenic contaminated groundwaters. In oxygenated environments arsenic is found in the +5 oxidation state and is readily removed through adsorption onto iron oxides. However, in South Asia, where arsenic exposure is most severe, arsenic is found in the +3 oxidation state. This species is both more toxic and more difficult to remove than As(V). The current generation of arsenic treatment plants often fail to meet the World Health Organisation’s 10 μg L-1 guideline limit, and the oxidation of As(III) to As(V) is therefore necessary to achieve effective removal of arsenic in South Asia. Multifunctional photocatalyst-sorbents are an attractive solution, as a single material can be used to both oxidise As(III) and adsorb As(V). Whilst multifunctional behaviour is often achieved by coupling different materials into new composite forms, our understanding of how material coupling influences the behaviour of each component (i.e. photocatalytic oxidation and adsorption) remains limited. This thesis investigated a mesoporous TiO2/Fe2O3 composite. This work found that monolayer adsorption of As(V) is component additive, with TiO2 and Fe2O3 surface components behaving independently of one another. Multilayer adsorption of As(III) is not component additive, due to differences between the surface morphology of meso-TiO2/Fe2O3 and single-phase reference samples. Coupling TiO2 with Fe2O3 significantly reduced photocatalytic activity, due to parasitic absorption of ultraviolet light by the Fe2O3 phase. The kinetic mechanism also changed after coupling, from a reactive oxygen species (ROS) mediated pathway to direct surface oxidation. This work considered the balance between the high sorbent concentrations needed for long filter device life-times, and the low photocatalyst concentrations needed to achieve effective light penetration through TiO2 suspensions. Kinetic adsorption modelling predicted that at least 10 g L-1 material is required for effective arsenic removal, presenting constraints on how this technology can be engineered.

description: We report enhanced interlayer tunneling with reduced linewidth at zero interlayer bias in a twist- controlled double monolayer graphene heterostructure in the quantum Hall regime, when the top (νT) and bottom (νB) layer ﬁlling factors are near νT = ±1/2, ±3/2 and νB = ±1/2, ±3/2, and the total ﬁlling factor ν = ±1 or ±3. The zero-bias interlayer conductance peaks are stable against variations of layer ﬁlling factor, and signal the emergence of interlayer phase coherence. Our results highlight twist-control as a key attribute in revealing interlayer coherence using tunneling.

Les propriétés du béton ont été étudiées à partir de dix compositions dans la classe de résistance C35/45 avec une même ouvrabilité plastique S2 et de classe d’environnement EA2. Seulement, les graviers recyclés ont subi une pré-saturation pendant 24 h, Ils sont incorporés à l’état saturé à surface sèche. Les résultats obtenus montrent que les résistances caractéristiques des différents bétons ordinaires recyclés sont généralement satisfaisantes. La substitution des granulats naturels par les recyclés à un pourcentage de 30%, limite trouvée dans la littérature, n’a pas influencée les propriétés de ces béton que ce soient mécaniques ou de durabilité ; Particulièrement avec celui du gravier recyclé dont son taux de substitution peut atteindre les 50%.

description: The world astronomical image archives represent huge opportunities to time-domain astronomy sciences and other hot topics such as space defense, and astronomical observatories should improve this wealth and make it more accessible in the big data era. In 2010 we introduced the Mega-Archive database and the Mega-Precovery server for data mining images containing Solar system bodies, with focus on near Earth asteroids (NEAs). This paper presents the improvements and introduces some new related data mining tools developed during the last five years. Currently, the Mega-Archive has indexed 15 million images available from six major collections (CADC, ESO, ING, LCOGT, NVO and SMOKA) and other instrument archives and surveys. This meta-data index collection is daily updated (since 2014) by a crawler which performs automated query of five major collections. Since 2016, these data mining tools run to the new dedicated EURONEAR server, and the database migrated to SQL engine which supports robust and fast queries. To constrain the area to search moving or fixed objects in images taken by large mosaic cameras, we built the graphical tools FindCCD and FindCCD for Fixed Objects which overlay the targets across one of seven mosaic cameras (Subaru-SuprimeCam, VST-OmegaCam, INT-WFC, VISTA-VIRCAM, CFHT-MegaCam, Blanco-DECam and Subaru-HSC), also plotting the uncertainty ellipse for poorly observed NEAs. In 2017 we improved Mega-Precovery, which offers now two options for calculus of the ephemerides and three options for the input (objects defined by designation, orbit or observations). Additionally, we developed Mega-Archive for Fixed Objects (MASFO) and Mega-Archive Search for Double Stars (MASDS). We believe that the huge potential of science imaging archives is still insufficiently exploited.

description: Les matériaux composites à matrice cimentaire et renfort textile sont l’une des solutions à fort potentiel de réparation et renforcement des structures de génie civil. Ce type de composite est caractérisé par des propriétés mécaniques adéquates et une facilité de mise en œuvre exceptionnelle. Son comportement mécanique a fait l’objet de plusieurs études dans le but de le caractériser et de comprendre les paramètres régissant son comportement. Cependant, ces études sont limitées généralement à des techniques de mesure focalisées sur la surface des éprouvettes, puis le comportement interne est déduit par des approches de la mécanique des milieux continus et de la rupture. Ce travail consiste à mesurer localement la déformation interne d’un composite à matrice cimentaire, en utilisant des fibres optiques comme capteur de déformation répartie, et d’en déduire le comportement interne de la matrice et du renfort textile au cours d’un essai de traction. Les résultats obtenus sont confrontés avec les approches théoriques utilisées pour la modélisation du comportement de ce type de composite.

description: Heavy metal-based two-dimensional van der Waals materials have a large, coupled spin and valley Hall effect (SVHE) that has potential use in spintronics and valleytronics. Optical measurements of the SVHE have largely been performed below 30 K and understanding of the SVHE-induced spin/valley polarizations that can be electrically generated is limited. Here, we study the SVHE in monolayer p-type tungsten diselenide (WSe2). Kerr rotation (KR) measurements show the spatial distribution of the SVHE at different temperatures, its persistence up to 160 K, and that it can be electrically modulated via gate and drain bias. A spin/valley drift and diffusion model together with reflection spectra data is used to interpret the KR data and predict a lower-bound spin/valley lifetime of 4.1 ns below 90 K and 0.26 ns at 160 K. The excess spin and valley per unit length along the edge is calculated to be 109 per micron at 45 K, which corresponds to a spin/valley polarization on the edge of 6%. These results are important steps towards practical use of the SVHE.

description: By means of grid-based, 3D hydrodynamical simulations we study the formation of second generation (SG) stars in a young globular cluster (GC) of mass 10^7 Msun, the possible progenitor of an old GC with a present mass ~(1-5) * 10^6 Msun. The cluster accretes external gas as its first generation (FG) asymptotic giant branch (AGB) stars release their ejecta and SG stars form. We consider two models characterised by different densities of the external gas. In both cases, we find that a very compact SG subsystem with central density >10^5M sun/pc^3 forms in the innermost regions of the cluster. The low-density model forms a population of extreme SG stars with high helium enhancement, followed by the formation of another SG group out of a mix of pristine gas and AGB ejecta and characterised by a modest helium enhancement. On the other hand, the high-density model forms in prevalence SG stars with modest helium enhancement. Our simulations illustrate the dynamical processes governing the formation of SG populations in GCs and shed light on the structural properties emerging at the end of this phase. The newly born SG groups have different concentrations, with more extreme SG stars more centrally concentrated than those with less extreme chemical abundances. The very high density of the SG subsystems implies that SG massive stars, if formed, might suffer frequent close encounters, collisions and gas stripping, thus possibly contributing further gas to the SG formation.

description: In recent years, a number of purpose-built scintillator-based polarimeters have studied bright astronomical sources for the first time in the hard X-ray band (tens to hundreds of keV). The addition of polarimetry can help data interpretation by resolving model-dependent degeneracies. The typical instrument approach is that incident X-rays scatter off a plastic scintillator into an adjacent scintillator cell. In all missions to date, the scintillators are read out using traditional vacuum tube photo-multipliers (PMTs). The advent of solid-state PMTs ("silicon PM" or "MPPC") is attractive for space-based instruments since the devices are compact, robust and require a low bias voltage. We have characterised the plastic scintillator, EJ-248M, optically coupled to a multi-pixel photon counter (MPPC) and read out with the Citiroc ASIC. A light-yield of 1.6 photoelectrons/keV has been obtained, with a low energy detection threshold of $\lesssim$5 keV at room temperature. We have also constructed an MPPC-based polarimeter-demonstrator in order to investigate the feasibility of such an approach for future instruments. Incident X-rays scatter from a plastic-scintillator bar to surrounding cerium-doped GAGG (Gadolinium Aluminium Gallium Garnet) scintillators yielding time-coincident signals in the scintillators. We have determined the polarimetric response of this set-up using both unpolarised and polarised $\sim$50 keV X-rays. We observe a clear asymmetry in the GAGG counting rates for the polarised beam. The low-energy detection threshold in the plastic scintillator can be further reduced using a coincidence technique. The demonstrated polarimeter design shows promise as a space-based Compton polarimeter and we discuss ways in which our polarimeter can be adapted for such a mission.

description: Les composites TRC sont des matériaux constitués d’une matrice minérale contenant des granulats très fins et d’un renfort à base de fils multi-filaments de verre, de basalte, d’aramide ou de carbone. Grâce à leurs principaux avantages (grande résistance en traction, comportement pseudo-ductile, non toxicité, etc.), ces matériaux peuvent être appropriés pour plusieurs applications en génie civil, que ce soit pour la préfabrication des éléments de structures ou bien pour la réparation et le renforcement des anciens éléments en béton armé ou d’autre matériaux traditionnels. Cependant, l’efficacité du renfort du composite est souvent limitée par la faible pénétration des particules de la matrice dans les filaments internes du fil, ce qui entraine une rupture prématurée du matériau en raison de la faible adhérence fil-matrice. Afin d’améliorer cette adhérence, le renfort est généralement pré-imprégné par voie humide par des charges minérales ou polymères. L’objectif de ce travail est de comparer cette méthode classique de pré-imprégnation par une méthode alternative appelée pré-imprégnation par voie sèche. Elle se base sur l’application d’un champ électrostatique alternatif qui permet la pénétration de la poudre au sein du fil. Une campagne d’essai de traction sur des composites fils de verre-matrice ettringitique, a été menée. Trois configurations ont été testées : fil sec (S), fil pré-imprégné par voie humide (PIH) et fil préimprégné par voie sèche (PIS) par différents types de poudre. Cette caractérisation mécanique et microscopique a permis de mettre en lumière l’effet de la pré-imprégnation sur la résistance des composites.

description: Monolayer molybdenum disulﬁde has been previously discovered to exhibit non-volatile resistive switching behavior in a vertical metal-insulator-metal structure, featuring ultra-thin sub-nanometer active layer thickness. However, the reliability of these nascent 2D-based memory devices was not previously investigated for practical applications. Here, we employ an electron irradiation treatment on monolayer MoS2 ﬁlm to modify the defect properties. Raman, photoluminescence, and X-ray photoelectron spectroscopy measurements have been performed to conﬁrm the increasing amount of sulfur vacancies introduced by the e-beam irradiation process. The statistical electrical studies reveal the reliability can be improved by up to 1.5× for yield and 11× for average DC cycling endurance in the devices with a moderate radiation dose compared to unirradiated devices. Based on our previously proposed virtual conductive-point model with the metal ion substitution into sulfur vacancy, Monte Carlo simulations have been performed to illustrate the irradiation effect on device reliability, elucidating a clustering failure mechanism. This work provides an approach by electron irradiation to enhance the reliability of 2D memory devices and inspires further research in defect engineering to precisely control the switching properties for a wide range of applications from memory computing to radio- frequency switches.

description: Coronal rain is the well-known phenomenon in which hot plasma high in the Sun's corona undergoes rapid cooling (from > 10^6 K to < 10^4 K), condenses, and falls to the surface. Coronal rain appears frequently in active region coronal loops and is very common in post-flare loops. This Letter presents discovery observations, which show that coronal rain is ubiquitous in the embedded bipole very near a coronal hole boundary. Our observed structures formed when the photospheric decay of active region leading sunspots resulted in a large parasitic polarity embedded in a background unipolar region. We observe coronal rain to appear within the legs of closed loops well under the fan surface, as well as preferentially near separatrices of the resulting coronal topology: the spine lines, null point, and fan surface. We analyze 3 events using SDO Atmospheric Imaging Assembly (AIA) observations in the 304, 171, and 211 {/AA} channels, as well as SDO Helioseismic and Magnetic Imager (HMI) magnetograms. The frequency of rain formation and the ease with which it is observed strongly suggests that this phenomenon is generally present in null-point topologies of this size scale. We argue that these rain events could be explained by the classic process of thermal nonequilibrium or via interchange reconnection at the null; it is also possible that both mechanisms are present. Further studies with higher spatial resolution data and MHD simulations will be required to determine the exact mechanism(s).

description: We discuss the behavior of two point functions for Polyakov loops in a SU(3) gauge theory about the critical temperature, T_c. From a Z(3) model, in mean field theory we obtain a prediction for the ratio of masses at T_c, extracted from correlation functions for the imaginary and real parts of the Polyakov loop. This ratio is m_i/m_r = 3 if the potential only includes terms up to quartic order in the Polyakov loop; its value changes as pentic and hexatic interactions become important. The Polyakov Loop Model then predicts how m_i/m_r changes above T_c.

description: Les caractéristiques intrinsèques des granulats de bétons concassés(GBC) rendent difficile le contrôle de l’eau efficace réelle (Eeff(réelle)) lorsque ces granulats sont utilisés dans des nouveaux bétons recyclés. Le sens de migration de l'eau entre GBC et la pâte de ciment peut changer. L'eau peut entrer ou sortir des GBC, en fonction de leur niveau initial d'humidité et du mode de cette pré-humidification. Par conséquent, l’Eeff (réelle) dans le béton à base de GBC peut diminuer et/ou augmenter pendant le malaxage. Par Eeff (réelle), on entend ici la quantité d’eau réellement présente au sein de la pâte de ciment à un instant donné du malaxage, à l’exclusion de l’eau présente dans la porosité des granulats. Cette Eeff (réelle) est à opposer à l’eau efficace théorique, différence entre l’eau totale et l’eau absorbée par les granulats déterminée selon la norme EN 1097-6. L’objectif principal de ce travail est d’estimer l’évolution de l’Eeff (réelle) au cours et à la fin du malaxage des bétons de GBC. Pour ce faire un découpage pertinent des courbes de puissance consommée enregistrée lors du malaxage est proposé et basé sur des considérations physiques (étapes de l’agglomération humide). Ensuite une méthode est proposée à partir de ce découpage pour estimer l’évolution de l’Eeff (réelle) durant le malaxage ainsi que la capacité d’absorption des GBC.

Two-Dimensional Axisymmetric Collapse of Thermally Unstable Primordial Clouds

description: We have performed two-dimensional hydrodynamic simulations of the collapse of isolated axisymmetric clouds condensing via radiative cooling in a primordial background gas. In order to study the development of the so-called ``shape-instability'', we have considered two types of axisymmetric clouds, oblate and prolate clouds of various sizes and with axial ratios of $0.5 \leq {R_{\rm c,R}} /{R_{\rm c,z}} \leq 2$. We find that the degree of oblateness or prolateness is enhanced during the initial cooling phase. But it can be reversed later, if the initial contrast in cooling times between the cloud gas and the background gas is much greater than one. In such cases an oblate cloud collapses to a structure composed of an outer thin disk and a central prolate component. A prolate cloud, on the other hand, becomes a thin cigar-shape structure with a central dense oblate component. The reversal of shape in the central part of the cooled clouds is due to supersonic motions either along the disk plane in the case of oblate clouds or along the symmetry axis in the case of prolate clouds. For a background gas of $T_h=1.7\times 10^6$K and $n_h=0.1 \cm3$ in a protogalactic halo environment, the mean density of the cloud gas that has cooled to $10^4$K increases to $100 n_h$ or so, in our simulations where nonequilibrium cooling is adopted and the background gas cools too. The spherical Jeans mass of such gas is estimated to be about $M_J \sim 5\times10^{7}\Msun$. In order for cloud mass to exceed the Jeans mass and at the same time in order for the thermal instability to operate, the initial cloud size should be around $1 - 1.5 l_{\rm cool}$ where $l_{\rm cool}$ is the cooling length.

description: Galactic-scale structure is of particular interest since it provides important clues to dark matter properties and its observation is improving. Weakly interacting massive particles (WIMPs) behave as cold dark matter on galactic scales, while beyond-WIMP candidates suppress galactic-scale structure formation. Suppression in the linear matter power spectrum has been conventionally characterized by a single parameter, the thermal warm dark matter mass. On the other hand, the shape of suppression depends on the underlying mechanism. It is necessary to introduce multiple parameters to cover a wide range of beyond-WIMP models. Once multiple parameters are introduced, it becomes harder to share results from one side to the other. In this work, we propose adopting neural network technique to facilitate the communication between the two sides. To demonstrate how to work out in a concrete manner, we consider a simplified model of light feebly interacting massive particles.

description: Thiosemicarbazones which previously characterized as a new class that inhibit anti-bovine viral diarrhea virus (BVDV) prompted us for synthesizing a series of new thiosemicarbazone derivatives. Thus, in this study, we reported the synthesis and antiviral evaluation of a series of 5-(arylazo)salicylaldehyde thiosemicarbazone derivatives for their expected antiviral activity. The desired products were synthesized from the condensation of 5-(arylazo)salicylaldehyde derivatives with N-(4)-substituted thiosemicarbazide derivatives. Antiviral screening was performed to test the anti-bovine viral diarrhea virus properties. From the obtained results, compounds 5, 23 and 24 showed highly selective activity against BVDV by blocking the viral RNA synthesis in cell culture. The BVDV in antiviral drug studies is valuable surrogate for the hepatitis C virus (HCV); so, the above results provided a novel candidate for the development of anti-HCV agents.

description: Afin d'assurer un démoulage de qualité du béton, l'agent de décoffrage doit former un film homogène sur le coffrage pour résister à la friction du béton sur les parois du coffrage. Une alternative pour réduire la quantité globale d’huile sur le chantier est l’utilisation des émulsions. Pour cela, il est important de contrôler son application et sa résistance pour assurer un bon décoffrage. L'adhérence et l'affinité avec le support ont été étudiées par l'adhérence de l'énergie solide/liquide. Cette énergie a été calculée en utilisant l'équation Zisman qui utilise l'angle de goutte et la tension de surface Liquide/Vapeur. L’évolution du film d’émulsion dans le temps est observée pour confirmer la stabilité du film après 15 min. Deux formulations commercialisées d'émulsion ont été comparées. Pour corréler ces résultats, le comportement des films d’émulsions à l’interface coffrage/béton a été étudié avec un tribomètre plan/plan créé pour les milieux complexes. Les premiers résultats montrent des performances tout à fait satisfaisantes comparées aux huiles.
