Abstract:
Geotechnical accidents often occur during road operation. To eliminate their consequences, various measures are required, taking into account the geological features of the site. Three cases of geotechnical accidents of road structures are considered: landslide damage to the bridge cone and the slope of the road embankment; the formation of a local landslide, plastic deformation and loss of stability of the roadbed, settlement of the culvert links; suffusion from the side of the railway cut under the cone of the bridge structure due to damage to the anti-filtration clay screen. In the first case, the reasons for the intensification of the landslide were periodic rises in the level of groundwater, the presence of areas not protected by vegetation, and areas of loose soil. The accident was eliminated by installing an anti-landslide structure made of bored piles, embedded with their lower ends into rocky ground. In the second case, the reasons were waterlogging due to heavy summer rains and melting snow next spring. To eliminate the accident, drainage was arranged in the adjacent territory; the soil was partially replaced, reinforcement with geotextiles was carried out, slopes with a berm were laid, the base of the subgrade was strengthened. In the third case, the removal of soil particles (suffusion) from the side of the railway excavation under the cone of the bridge structure occurred due to damage to the anti-filtration clay screen during the creation of the construction site. After the restoration of the screen and the drainage device, the suffusion was eliminated. The above examples show the importance of engineering and geological substantiation in the design of transport construction facilities.

The electronic of S-doped and N-doped anatase TiO2(001) surfaces were investigated using the density functional theory (DFT). Substitutional and interstitial configurations of N and S atoms doped in anatase TiO2(001) surface and sub-surface at different sites were considered and all the formation energies were obtained. The perfect strutures of atoms doping were obstained by formation energies comparisions. The electronic structures of the results indicated that the elemental doping has much more efficient and stable photocatalyst than the pristine one, which narrowed the band gap of TiO2and improved its visible-light response activity.

Abstract:
The crystal and molecular strutures of two solvated forms of [K(18c6)]OAc (18c6 = 18-crown-6 = 1,4,7,10,13,16-hexaoxacyclooctadecane and OAc = acetate) were determined by single-crystal X-ray diffraction, namely (acetato-κ2O,O′)(1,4,7,10,13,16-hexaoxacyclooctadecane-κ6O)potassium dihydrate, [K(CH3COO)(C12H24O6)]·2H2O (1) and (acetato-κ2O,O′)aqua(1,4,7,10,13,16-hexaoxacyclooctadecane-κ6O)potassium acetic acid monosolvate [K(CH3COO)(C12H24O6)(H2O)]·CH3COOH (2). In both compounds, the acetate anion is bonded to the potassium ion in a chelating fashion and the metal atom is consequently slightly displaced from the O6plane of the crown ether. In the crystals, O—H...O hydrogen bonds lead to a polymeric ladder structure in the dihydrate1, while the acetic acid hydrate2features inversion dimers.

Abstract:
Porous poly (1-naphthylamine) were synthesized by interfacial polymerization method. The effects of several reaction conditions including oxidant/monomer molar ratio, polymerization temperature and reaction time on the polymerization yield have been investigated. The highest yield of poly (1-naphthylamine) was up to 73% at oxidant/monomer molar ratio of 3 and polymerization temperature of 25 °C for over 20h. Using FT-IR and XRD to analyze the structure of the obtained polymer, the results show that the main mode of connection for 1-naphthylamine units was linking N to para-C and it formed amorphous polymer with some ordered strutures. The micro-morphology of the polymer observed by SEM was found to have irregular porous structure with pore size less than 5μm, which may be related to the “self-emulsion effect” during polymerization.

Abstract:
Le développement industriel des Alliages à Mémoire de Forme est étroitement lié au processus de conception exigeant la mise au point d'outils numériques performants permettant la simulation de leurs comportements complexes. Le modèle phénoménologique tridimensionnel de la superélasticité des AMF ainsi développé dérive de la théorie des matériaux standards généralisés et des modèles classiques de la plasticité. Son extension au cas des transformations finies s'appuie sur les notions de configuration intermédiaire déformée et de vecteurs directeurs. L'intégration numérique des lois de comportement du modèle au moyen d'une méthode implicite a permis l'implantation dans le code éléments finis Castem 2000Ò. Enfin, l'intégration du modèle dans un contexte d'élément fini de coque spécifique, a été validée par comparaison avec des essais expérimentaux. Ceci permet d'envisager des calculs sur des structures très minces en transformations finies pour des trajets de chargement proportionnels
The Shape Memory Alloys industrial development is narrowly connected to the design process requiring the perfecting of efficient numerical tools which allow to simulate their complex behaviours. The SMA superelasticity tridimensional phenomenological model so developed comes from the generalized standard materials theory and the classical plasticity models. The expansion to the finite transformations case relies on the deformed intermediate configuration and the director vectors concepts. The model constitutive laws numerical integration with an implicit method allowed then the implementation in the finite element code Castem 2000Ò. At last, the comparison with experimental tests allowed the validation of the model integration in a specific shell finite element context. Thus, it permits to consider the finite transformations computations for very thin structures under proportional loadings

Abstract:
De nos jours une numérisation en masse de documents permet une large diffusion de ceux-ci. Pour faciliter l’accès aux informations contenues dans certains de ces documents, nous nous intéressons à la reconnaissance d’une classe de documents structurés, les tableaux. Cette thèse présente un langage de description de tableaux associé à un système de reconnaissance. Ce langage simple et intuitif permet de décrire des descriptions de structures tabulaires complexes et variables ainsi que des descriptions plus précises. Celles-ci permettent à l’analyseur de compenser les informations manquantes et d’absorber le bruit Pour concevoir l’analyseur et l’utilisation des informations des descriptions, nous proposons une représentation interne et introduisons le concept d’intersections finales. Celles-ci aident à caractériser la structure des tableaux. Pour valider notre système, nous présentons des résultats sur des structures de tableaux très variées et sur plus de 50 000 documents d’archives
ANowadays, a mass digitization of documents gives access to a large quantity of documents. To give better access to the information in some of these documents, we focus on the recognition of a structured document class, tables. This dissertation presents a table description language linked to a recognition system This simple and intuitive language enables to describe complex and variable table structures as well as more precise descriptions to allow the analyzer compensate for lacking information, and to better absorb noise. To design this analyzer and the use of information from the descriptions, we propose an internal representation and introduce the concept of final intersections. These intersections help to characterize table structures. To validate our system, we present results on very variable table structures and on over 50,000 old documents

Abstract:
Nous étudions expérimentalement le transport dépendant du spin d’électrons chauds dans des multicouches (MC) magnétiques, qui contiennent des couches uniques magnétiques, ou des tricouches de type « vannes de spin » (VS). Pour cela, nous avons mis en œuvre la microscopie à émission d’électrons balistiques (BEEM), une extension à trois contacts de la microscopie à effet tunnel sur des structures métal/semiconducteur. La méthode mise au point pour satisfaire les nombreuses contraintes imposées par le BEEM sur les échantillons est décrite en détail. La transmission des électrons chauds dans des MC a été systématiquement mesurée dans la gamme d’énergie 1-2 eV au dessus du niveau de Fermi. De l’étude en fonction des épaisseurs des couches magnétiques nous avons déduit les longueurs d’atténuation des électrons chauds en fonction du spin et de l’énergie. Ces mesures, sur le cobalt et l’alliage doux NiFe, sont comparées à des calculs et résultats expérimentaux de la littérature. Pour des épaisseurs inférieures à la monocouche atomique, une organisation spatialement hétérogène a été observée, avec un effet très important sur la transmission BEEM, variant sur une échelle sub-nanométrique. En mode imagerie, nous avons étudié les configurations magnétiques de VS, en particulier des parois à 360° dans des couches de cobalt. Les effets de l’intensité et la direction du champ appliqué sur la structure de ces parois ont été observés. Ces résultats ont été comparés quantitativement à des calculs micromagnétiques, avec un accord excellent. Ceci a permis de montrer que la résolution magnétique de BEEM est meilleure que 50 nm
In this work, we experimentally study spin-dependent hot electron transport through metallic multilayers (ML), containing single magnetic layers or “spin-valve” (SV) trilayers. For this purpose, we have set up a ballistic electron emission microscope (BEEM), a three terminal extension of scanning tunnelling microscopy on metal/semiconductor structures. The implementation of the BEEM requirements into the sample fabrication is described in detail. Using BEEM, the hot electron transmission through the ML’s was systematically measured in the energy range 1-2 eV above the Fermi level. By varying the magnetic layer thickness, the spin-dependent hot electron attenuation lengths were deduced. For the materials studied (Co and NiFe), they were compared to calculations and other determinations in the literature. For sub-monolayer thickness, a non uniform morphology was observed, with large transmission variations over sub-nanometric distances. This effect is not yet fully understood. In the imaging mode, the magnetic configurations of SV’s were studied under field, focussing on 360° domain walls in Co layers. The effects of the applied field intensity and direction on the DW structure were studied. The results were compared quantitatively to micromagnetic calculations, with an excellent agreement. From this, it can be shown that the BEEM magnetic resolution is better than 50 mn

Abstract:
Les matériaux possédant à la fois des propriétés optiques et électriques sont d’un grand intérêt car ils sont utilisés dans de nombreuses applications comme par exemple les cellules photovoltaïques, les LED, les phototransitors ou encore les photodétecteurs. Actuellement, les dispositifs commercialisés sont constitués soit de matériaux complètement inorganiques soit de matériaux complètement organiques. Les matériaux hybrides organiques-inorganiques sont très intéressants dans la mesure où ils sont capables de présenter une robustesse, une stabilité et un coût intermédiaire aux matériaux entièrement inorganiques ou organiques. Ce manuscrit porte sur la synthèse par électrodéposition de nouveaux films hybrides organiques-inorganiques auto-assemblés à propriétés électriques et optiques. Nous présentons dans cet ouvrage trois systèmes hybrides (ZnO/Dodécylsulfate de sodium, ZnO/Acide 2-naphtoïque et ZnO/Acide téréphtalique) incluant chacun plusieurs phases hybrides. Pour chaque système une étude préalable par synthèses en solution et hydrothermale a été menée afin d’identifier les phases formées et de les caractériser
Materials owning optical and electrical properties are interesting as they are used in many applications as solar cells, LEDs, phototransistors or photodetectors. Currently only organic or inorganic devices are commercialized. Hybrid organic-inorganic materials are attractive as much as they might have robustness, stability and cost in an intermediate state between all-organic or all-inorganic materials. This manuscript deals with the synthesis by electrodeposition of self-assembly of new hybrid organic-inorganic films with electrical and optical properties. We present here three hybrid systems (ZnO/Sodium dodecylsulfate, ZnO/2-naphthoic acid and ZnO/terephthalic acid) and the hybrid phases included in each system. A preliminary study with solution and hydrothermal synthesis is also presented for each system. Both synthesis methods were useful to identify and characterize the different synthesized phases

Abstract:
L’splicing és el mecanisme pel qual els introns són eliminats del pre-mRNA per generar un trànscrit madur. Aquest procés és dut a terme per un complex macromolecular anomenat spliceosoma i requereix el reconeixement dels senyals d’splicing al pre-mRNA. Aquests senyals no són sempre identificats correctament, el que permet la producció de trànscrits diferents a partir d’un únic pre-mRNA mitjançant un procés anomenat splicing alternatiu. Aquest procés pot ser regulat mitjançant factors proteics específics o per altres mecanismes que alteren el reconeixement dels senyals d’splicing com l’estructura secundària adoptada pels pre-mRNAs.

Splicing is the mechanism by which introns are removed from the pre-mRNA to create a mature transcript. This process is performed by a macromolecular complex, the spliceosome, and involves the recognition of the splicing signals in the premRNA. These signals are not always perfectly recognized, which allows the production of different mature transcripts from a single pre-mRNA through a process called alternative splicing. This process can be regulated by specific protein factors or by other mechanisms that affect the recognition of the splicing signals, such as the secondary structure adopted by the pre-mRNA. In this thesis we have investigated the mechanisms of splicing regulation in eukaryotes using computational approaches. Moreover, we have also studied the relationship that exists between protein factors involved in splicing regulation and splicing signals, and how they have co-evolved across species. Finally, and considering the possibilities that alternative splicing can offer from the evolutionary point of view, he have also analyzed the impact of alternative splicing in gene evolution.

Abstract:
L’splicing és el mecanisme pel qual els introns són eliminats del pre-mRNA per generar un trànscrit madur. Aquest procés és dut a terme per un complex macromolecular anomenat spliceosoma i requereix el reconeixement dels senyals d’splicing al pre-mRNA. Aquests senyals no són sempre identificats correctament, el que permet la producció de trànscrits diferents a partir d’un únic pre-mRNA mitjançant un procés anomenat splicing alternatiu. Aquest procés pot ser regulat mitjançant factors proteics específics o per altres mecanismes que alteren el reconeixement dels senyals d’splicing com l’estructura secundària adoptada pels pre-mRNAs. En aquesta tesi hem investigat els mecanismes de regulació de l’splicing en eucariotes mitjançant tècniques computacionals. També hem estudiat la relació existent entre les proteïnes que intervenen en la regulació de l’splicing i els senyals d’splicing, i com han coevolucionat en diferents espècies.

Abstract:
Abstract Palms, because of their simple architecture, provide ideal objects for the study of economy and efficiency in organic construction. They have unbranched axes, each of which supports a terminal tuft of appendages (leaves), each leaf supported by a basal sheath. The palm stem represents the reinforced concrete of the structural engineer (Fig. 6.1), since its tissues can be thought of as a series of axially-orientated vascular bundles (steel rods) embedded in a parenchymatous ground tissue (concrete matrix). Unlike the engineer’s reinforced concrete, the vascular bundles of the palm stem are not necessarily uniformly distributed, but usually concentrated toward the stem periphery for maximum efficiency. The stem of many palms has an additional mechanical feature, unfamiliar to human engineers, in that it can increase its stiffness with age. This is a very efficient way of growing because it means that the palm is not excessively overbuilt. It is as if an engineer could design a struture that becomes increasingly stronger directly as increasing strength is required. If the life span of the structure is shortened accidentally by some factor other than mechanical failure, the initial investment in the aborted structure is minimized. In terms of the palm tree this ‘saved’ investment can be diverted to more appropriate ecological events, such as growing in height, or in reproduction.

Abstract The focus of this chapter is the use of Cabo Verdean Creole as a language of instruction in Baystate Public Schools. The authors discuss the development of the Cabo Verdean Heritage Language and Culture curriculum that took place during Summer and Fall 2020, designed specifically to meet the needs of Cabo Verdean learners of English currently attending Baystate Public Schools. The curriculum was implemented in 2021. This chapter provides a brief historical overview of the use of Cabo Verdean Creole in Massachusetts Bilingual Education programs and then describes the overall vision for a new policy regarding the use of mother tongues in educational systems, which is driving the Cabo Verdean Center for Applied Research (CVCAR) to conceptualize and implement this new curriculum for Cabo Verdean learners of English. The authors introduce the various components of the curriculum while demonstrating that linguistic frameworks can be used successfully when they are applied in the instruction of Cabo Verdean learners of English.

Abstract:
Abstract A general procedure for the optimization of the parameters of dynamic neutralizes is presented. It can be applied to the minimization of the vibration response and sound radiation of linear strutures subjected to excitations in a specified frequency range. Modal theory and generalized equivalent quantity concept for the neutralizers, introduced by Espíndola and Silva (1992), are applied to a non-linear optimization scheme. The proposed procedure can be applied to relaxed and time invariant structures. It is not dependent on the struture complexity and the degree of discretization adopted. In such conditions, a significant reduction in computing work is achieved, if compared with the more traditional methods.

Abstract:
Optical fiber ring resonators using directional couplers as signal tapping elements are called to play an important role in the future all-optical communication and sensor networks. The possibility of obtaining a wide range of strutures capable of performing wide-band signal processing operations in a guided-wave format has attracted the interest of several research groups. Initial effort focused on structures operating under linear regime showing and demonstrating potential applications as fiber sensors [1], all-fiber lasers [2], Fabry-Perot and Mach-Zehnder interferometers [3], [4], and optical filters for WDM and OFDM [5].

Abstract:
<p>Protection systems against impacts of vessels on bridge supports are essential to guarantee the structural integrity of bridges and the safety of users, avoiding the ruin of supports or the collapse of parts or the entire structure of the bridge, thus guaranteeing its functionality and prolonging its service life. These structures have their specificities and the definition of the type of protection to be adopted and its sizing must consider the environment conditions of the region. In the Brazilian standardizations, there are design criteria and specifications that contemplate the navigable spans considering the width of the vessels only, which has been insufficient for navigation in the region of bridges crossing navigable channels/rivers in Pará, North Region of Brazil. In evaluating the accidents that have been taking place in Pará, it appears that these criteria are insufficient to protect bridge structures from the severe accidents that have occurred in the last 10 years.</p>
