Abstract (sommario):
In the “Star Wars” movies, Jedi knights engage in dazzling duels with lightsabers that confine light and push it against each other. However, confining photons or enabling their interaction in reality, especially in free space, is extremely challenging. Photon-photon interactions, which are only possible through optical nonlinearity, are difficult to achieve with conventional materials. The quest to confine photons in a specific space for as long as possible, and to allow individual photons to interact with each other, is a major challenge for researchers in physics and optics. Since the invention of the laser, the study of optical nonlinearity has been the foundation of various modern scientific and technological advances that contribute significantly to our daily lives. Recently, optical nonlinearity has become a central platform for quantum information, computing, and sensing research, highlighting its growing importance. This article discusses a new turning point in optical nonlinearity based on micro-resonators, and presents efforts and future perspectives to realize photon-photon interactions.

Abstract (sommario):
Smart hydrogels are soft materials which can be applied in sensors and actuators especially in microfluidics in which the fluid–structure interaction is important. In this work, first, the behavior of a one-way hydrogel micro-valve is investigated by considering the fluid–structure interaction effect for a specified geometry of the micro-valve. Second, both the fluid–structure interaction and non-fluid–structure interaction simulations are conducted to study the fluid flow effect on the operational parameters of the micro-valve. The obtained results show that the fluid–structure interaction effects are important and have a considerable influence on the micro-valve parameters especially on its closing temperature. Thereafter, a precise study on the micro-valve is executed by considering the micro-valve operational parameters such as inlet pressure, head size, crosslinking density, and breaking pressure at different temperatures. The results show the importance of considering the fluid–structure interaction effect in the design of these devices.

Abstract (sommario):
The thesis explores the sources of energy inefficiency in asymmetric multi- core architectures where energy efficiency is measured by the energy-delay squared product. The insights gathered from this study drive the development of optimized thread scheduling and coordinated cache management strategies in an important class of asymmetric shared memory architectures. The proposed techniques are founded on well known mathematical optimization techniques yet are lightweight enough to be implemented in practical systems.

Abstract (sommario):
Ce travail s'inscrit dans le cadre du Projet National de Recherche français "Microtunnels". Le rnicrotunnelage est une technique de pose de canalisations sans tranchée. Elle consiste à foncer la canalisation à l'arrière d'un microtunnelier ayant les fonctions d'excavation, de marinage et de guidage. Cette méthode récente, permettant de réduire les nuisances liées à la pose des réseaux en tranchée, se développe principalement dans le cadre du génie civil urbain. Cette étude essentiellement expérimentale concerne principalement les problèmes liés au frottement à l'interface sol-canalisation, à la stabilité du front de taille, et enfin aux mouvements induits au sein du massif de sol traversé. Une première phase d'observations de terrain, basée sur le sui vi complet de chantiers de rnicrotunnelage dans des conditions de sol diverses, comportait la caractérisation des terrains traversés ainsi que l'enregistrement des principaux paramètres de fonçage et de pilotage. L'interprétation de ces données a permis de mettre en évidence l'incidence de la nature des terrains, de la surcoupe, de la lubrification et des problèmes de guidage sur les frottements mobilisent, sans permettre toutefois de toujours faire la part de chacun de ces paramètres. Les problèmes de stabilité du front et leur incidence sur les mouvements du sol ont pu également être observés et analysés. A partir de ces résultats, une étude complémentaire, dans des conditions bien contrôlées, a été entreprise dans une chambre de calibration adaptée à la modélisation du fonçage de canalisations. Les essais réalisés ont permis de cerner plus précisément l'incidence de la surcoupe et de l'injection de lubrifiant sur les frottements mobilisés et sur les mouvements engendrés dans le massif. L'incidence de la surcoupe a été modélisée à l'aide de simulations numériques bidimensionnelles en vue de l'extension aux conditions institue
This work comes within the scope of the « Microtunnels » French National Project. The micro-tunneling technique is a trenchless process for installing small diameter pipes. It consists in jacking pipe elements behind the boring machine performing excavation, spoil removal and steering operations. The main advantage of this recent method is a reduction in disturbances compared to traditional open-trench techniques. Therefore, it is especially useful and adapted in urban areas. This experimental study principally focuses on the main aspects of the technique:. / soil/pipe interface friction,. / face stability. / ground movements induced by microtunneling technique. In the first part, the complete monitoring at several microtunneling sites is reported. In particular, encountered soils are characterized (through in-situ and laboratory tests) and the main jacking and steering data are monitored. The in depth analysis of these data shows the great influence of ground nature, overcut, lubrication and pipe misalignments on mobilized friction. However, the respective contribution of each of the aforementioned parameters is not clearly identified. Face stability and ground \. 10vements are also observed and analyzed. Based on these in-situ results, a complementary experimentation has been designed and set up. Pipe jacking has been reproduced in a calibration chamber with a detailed and precise procedure and a full monitoring of ground displacements in the vicinity of the pipe and the pipe’s displacements and stresses. The influence of overcut, lubricant injection on the mobilized friction and the associated ground movements is precisely evaluated. In addition. The overcut effect has been simulated by numerical 2D calculations in order to use them to in-situ conditions

Abstract (sommario):
Cette thèse traite de l'action des ondes acoustiques sur des bulles micrométriques excitées à leur fréquence de résonance. En effet, les bulles peuvent être considérées comme des oscillateurs mécaniques et les forces acoustiques à leur résonance, appelées forces de Bjerknes, ont des propriétés non triviales. De plus, les bulles interagissent entre elles par l'émission d'un champ secondaire, menant à leur auto-organisation sur un motif périodique. Ici, les bulles sont confinées dans des microcanaux, elles ne sont pas sphériques et frottent fortement sur les parois. L'étude expérimentale des forces acoustiques (primaire et secondaire) est alors précédée par la modélisation de l'écoulement des bulles, liant la friction sur les parois aux forces externes appliquées. Plusieurs applications aux laboratoires sur puce sont développées, dont le tri en taille, la division asymétrique contrôlée, l'aiguillage automatique à une bifurcation, et la manipulation de goutte.

Abstract (sommario):
Cette thèse de doctorat présente une recherche expérimentale innovante sur la réponse mécanique du sable à la croissance des racines des plantes. L'interaction entre les racines et le sol est étudiée pour deux systèmes racinaires différents -- correspondant au maïs et au pois chiche -- et deux granulométries différentes du sable d’Hostun, dans deux états de porosité initiale.Un protocole est mis au point afin de créer des échantillons présentant une bonne répétabilité de leurs propriétés initiales, et représentatifs des interactions naturelles entre racines et sol. Deux campagnes expérimentales ont été conduites sur la base de séries d’échantillons comportant différentes plantes et différents états initiaux de sable. Une analyse 4D (3D + temps) de l'interaction est effectuée grâce à la tomographie à rayons X.Chaque échantillon est scanné en moyenne 7 fois, depuis le jour du semis jusqu'au 7e jour de développement du système racinaire. Un traitement d’image spécifique a été développé et appliqué aux images 3D reconstruites à partir des radiographies à rayons x. Ce traitement d’image permet entre autres d’identifier le système racinaire ainsi que les grains de sable, mais aussi de déterminer la teneur en eau locale du sol. Ainsi, un volume comportant quatre phases, représentatif du système sol-racines, est défini pour chaque état auquel un échantillon est imagé. Par ailleurs, en s’appuyant sur les images 3D en niveaux de gris, la cinématique du système est mesurée par application de corrélations d’images dites locales et discrètes.Les mesures de porosité locale (déduites des volumes à 4 phases) et les champs de déformation du sable (déduits des corrélations d’images) sont détaillés pour chaque configuration initiale du système sable-plante.Concernant l’impact de l’état initial du sable sur le développement des systèmes racinaires : la comparaison des différentes configurations montre, entre autres, que la densité du sable joue un rôle clef sur l’expansion du système racinaire, ceci pour les deux plantes considérées.Concernant la réponse du sable à la croissance des racines : le tenseur des déformations montre un cisaillement du sol lors de la croissance d’une racine. La zone cisaillée autour de la racine est plus large pour une plus faible densité initiale du sable. La détermination de la réponse volumique du sable à la croissance d’une racine, et sa dépendance à la densité du sol a aussi fait l’objet d’une attention particulière. Ainsi, dans la zone cisaillée, la sable présente une réponse purement dilatante pour les états initiaux les plus denses, alors que les états les plus lâches montrent un comportement contractant, particulièrement à distance de la racine. De telles réponses sont observées à la fois pour le maïs et le pois chiche. De plus, le comportement contractant, induit par le cisaillement à distance de la racine, est aussi confirmé pour les deux granulométries du sable pris dans l’état le plus lâche
This PhD thesis presents an innovative experimental investigation on the mechanical response of sand to plant root growth.Root-soil interaction is investigated for two different root systems -- Maize and Chickpea -- and two different gradings of Hostun sand with two initial porosities.An original protocol is developed aiming to create samples with repetitive initial nominal properties and representative of the natural interaction.Two experimental campaigns were run on a series of samples with different sands and plants.A 4D (3D+time) analysis of the interaction is carried out by using x-ray Computed Tomography.For each sample, an average of 7 x-rays scans is performed, from the day of the seed sowing up to 7-days-old root system.An image processing technique has been developed and it is applied to the 3D images resulting from the reconstruction of the x-ray scans. Through this image processing, the root system is identified, together with the sand grains and the water present in the system. Finally, a four-phased volume representative of the soil-root system can be defined for each state of the observed samples.Besides, from the 3D greyscale images of the samples, measurements of the kinematics of the system are obtained through local and discrete approaches of image correlation.Local sand porosity and deformations resulting from the four-phased volumes and the image correlations are detailed for one sample of each root-sand configuration.Regarding the impact of the initial sand state on the root system development, the comparison of the different configurations shows, among other things, that the sand density plays a key role on the expansion of the root system, for both plant species.Concerning the sand response to the root growth, the strain tensor computed with image correlation shows that a root shears the soil while growing and the sheared zone is wider when the initial bulk density is lower.This work focuses also on the determination of the sand volumetric response to root growth in the sheared zone and its dependency on the soil density.Sand response is purely dilatant for denser initial states, while the looser sand exhibits a contractant behaviour far from the root surface. Such a response is obtained in the case of both maize and chickpea. Moreover, the contractant behaviour induced by the shearing away from the root is confirmed also for both sand granulometries in a looser state

Abstract (sommario):
The ability of pathogens and their surrogate host cells to exchange molecules is at the core of all host-pathogen interaction processes. Small chemical molecule signals provide a rich vocabulary for cellular communication, and pathogens have evolved the capacity to modulate, mimic or hijack these signals in a defensive, exponentially increasing the scope and complexity of this chemical language between host cells and pathogens. The objective of this work is to use Raman microscopy (RMS) to analyze molecular changes during infection of human cells by intra- (Toxoplasma gondii) and extra-cellular (Acanthamoeba castellanii) protozoan parasites. The work is divided into two parts. Firstly, we studied host-pathogen biomolecular interaction by using RMS. Secondly, we employed stable isotopes substitution technique to induce spectral changes that are specific to the labelled molecules. In this approach mammalian cells are selectively grown in culture medium in which only certain molecules are substituted with stable-isotope counterparts, and the exchange of these molecules are monitored between individual mammalian cells and parasites in real-time. Our results show that Raman spectroscopy can be a great tool to understand the molecular processes that mediate the interaction between the pathogens and host cell by providing quantitative spatially- and temporally-resolved information regarding molecular trafficking and exchanges. A better understanding of these complex interactions will advance our understanding of microbial pathogenesis and potentially identify new therapeutic targets.

Abstract (sommario):
Dans ce manuscrit nous présentons une expérience de mesure optique ultrasensible des vibrations mécaniques d'un micro-miroir dans une cavité Fabry-Perot de grande finesse. Le micro-miroir est constitué d'un résonateur de taille micrométrique en silicium, de fréquence de résonance de l'ordre du mégahertz, sur lequel est déposé un traitement optique de haute réflectivité. La sensibilité très élevée des mesures interférométriques est en principe suffisante pour observer les fluctuations quantiques de point zéro du résonateur. Pour atteindre le régime où l'énergie d'agitation thermique du micro-résonateur devient négligeable devant celle de l'état quantique fondamental, sa température doit être inférieure à 30 microKelvin. Afin d'approcher cette température, nous avons utilisé à la fois des méthodes cryogéniques traditionnelles et une technique de refroidissement laser basée sur les effets dynamiques de la pression de radiation dans une cavité désaccordée. Nous avons ainsi étudié la possibilité de combiner mesures optiques de haute sensibilité et cryogénie en plaçant le micro-résonateur et la cavité dans un cryostat à circulation d'hélium liquide. Nous avons mesuré le spectre de bruit thermique à température cryogénique et réalisé un refroidissement par pression de radiation du micro-résonateur. Nous avons également étudié un nouveau mécanisme de couplage optomécanique à trois modes, à bandes latérales résolues, plus efficace pour refroidir un micro-résonateur. Nous avons mis en évidence à la fois un effet de réduction et d'augmentation de la température effective du micro-miroir selon le couplage des modes optiques. Cette technique permet également d'étudier le phénomène des instabilités paramétriques pouvant apparaître dans les interféromètres gravitationnels de seconde génération.

Abstract (sommario):
The fluid-structure interaction of reacting materials requires computational models capable of resolving the wide range of scales present in both the condensed phase energetic materials and the turbulent reacting gas phase. This effort is focused on the development of a micro-scale structural model designed to simulate heterogeneous energetic materials used for solid propellants and explosives. These two applications require a model that can track moving surfaces as the material burns, handle spontaneous formation of discontinuities such as cracks, model viscoelastic and viscoplastic materials, include finite-rate kinetics, and resolve both micro-scale features and macro-scale trends. Although a large set of computational models is applied to energetic materials, none meet all of these criteria. The Micro-Scale Dynamical Model serves as the basis for this work. The model is extended to add the capabilities required for energetic materials. Heterogeneous solid propellant burning simulations match experimental burn rate data and descriptions of material surface. Simulations of realistic heterogeneous plastic-bound explosives undergoing impact predict the formation of regions of localized heating called hotspots which may lead to detonation in the material. The location and intensity of these hotspots is found to vary with the material properties of the energetic crystal and binder and with the impact velocity. A statistical model of the hotspot peak temperatures for two frequently used energetic crystals indicates a linear relationship between the hotspot intensity and the impact velocity. This statistical model may be used to generate hotspot fields in macro-scale simulations incapable of resolving the micro-scale heating that occurs in heterogeneous explosives.

Abstract (sommario):
Micro lamb wave sensor is one of useful tools to study the membrane-fluid interaction, especially in interdisciplinary and not yet explored areas, such as gas sensing, aerodynamics, the multi-parameter decoupling and so on. This is because micro Lamb wave sensor holds high sensitivity, low losses and multi-modes. This thesis deals with the membrane-fluid interaction with micro lamb wave sensor is investigated, and the potential function method is used to analyze the dispersion curves, the displacements, the stress curves, etc. A model is built to analyze the modes distribution in micro Lamb wave sensor. The gase effects on lamb wave propagations are investigated. The applications of Lamb wave in aerodynamics and multi-parameters decoupling are discussed. The details are described as follows. In theory, combinations of the potential function method and the boundary conditions at all interfaces are used to analyze the membrane-fluid interaction. Compared with traditional plate shell theory, the particle movements in the membrane and fluid are taken into account in this method. Several aspects of the problem can be addressed, including the displacement, the stress, velocity dispersion curve, pointing vector, group velocity, energy velocity and so on. All of these are available to investigate the interaction at the membrane-fluid interface. In the case of micro Lamb wave sensor, the resonant modes can be excited and work simultaneously with the travelling modes, as the membrane is width limited and not large enough comparing with the wavelength of Lamb waves. The established model car reveal the mode distributions in micro Lamb wave device clearly and accurately. These works provide insight into the understandings of the modes in micro Lamb wave device, which is useful for further experiments. In literatures, little attention has been paid on the Lamb wavesۥ propagation near the membrane-gas interface, as both the density and sound velocity of gas are low. We aim to provide more studies of gases effects on the evanescent wave the leaky wave near the membrane-gas interface. It is shown that the relative frequency shifts in the low frequency range of the A0 mode (evanescent wave, EW) is rather important and the shape of the curve looks like ۥUۥ shape; in the high frequency range of this mode (leaky Lamb wave, LLW), the quality factor decreases rapidly when the Lamb wave phase velocity approaches the gas sound velocity. The Sº mode shows immune to gas loading, which is a good choice for a reference mode. This provides theoretical and experimental work for related fields in gas sensing. The application of membrane-gas interaction in aerodynamics in investigated theoretically and experimentally. The interaction between the gas flow boundary layer and the acoustic sound field (EW and LLW) at the membrane-gas interface can give out the parameter in the gas flow. The parameters in gas flow can be obtained from the measuring the interaction, which happens between the gas flow boundary layer and the acoustic sound field (EW and LLW) at the membrane gas interface. In the EW case, the thicknesss of the gas flow boundary layer and the penetration depth of the evanescent wave combined determine this interaction. When the Lamb wave phase velocity approaches the gas sound velocity, this effect is clearly observed. In the LLW case, it is shown experimentally that the gas flow has not evident effects on Lamb wave’s propagations. It suggests that Lamb wave is promising for applications in wind tunnel experiments, micro channels characterization, and can lead to multi-parameters measurements. The effects of the different physical parameters (density, sound velocity, viscosity, etc) on the modesۥ propagations at he membrane-liquid interface are studied. Combination of the relative frequency shifts of the A01 mode (he fundamental mode of low frequency A0 mode) and the A03 mode (the third harmonic wave of the A01 mode), the density and the sound velocity of liquid, but is amplitude changes with the viscosity. This work makes Lamb wave have promising applications in the investigation of the molecular thermodynamics, molecular labels free detection,etc
Cette thèse traite, théoriquement et expérimentalement, de l’interaction fluide-membrane dans un capteur a onde de Lamb. Un modèle est utilisé pour calculer les courbes de dispersion, le déplacement, les contraintes. Un autre modèle est utilisé pour analyser la distribution des modes. L’effet des gaz est étudié théoriquement et expérimentalement. Les applications des ondes de Lamb à l’aérodynamique et aux mesures multiparamétriques sont présentées. Voici quelques détails. Le premier modèle utilise les fonctions potentielles et recherche les fonctions solution des équations de propagation qui remplissent les conditions aux limites avec ou sans la présence d’un liquide. Ce modèle permet d’obtenir de nombreux paramètres, le déplacement des particules, les contraintes, le vecteur de Poynting, les vitesses de groupe et d’énergie etc. La membrane étant limitée dans le sens latéral il y a coexistence dans la membrane de modes stationnaires et d’ondes progressives. Un modèle donne la position et l’intensité relatives des modes. Le but est d’apporter des connaissances complémentaires sur l’action des gaz sur la propagation des ondes de Lamb. On montre que pour les basses fréquences de A0 (ondes évanescentes dans le gaz) l’action est principalement un changement de fréquence , tandis aux plus hautes fréquences de A0 (Ondes «fuyantes» l’action est principalement une atténuation. Le S0 mode étant très peu modifié par la présence de gaz. L’application de l’interaction gaz-membrane en aérodynamique est étudiée théoriquement et expérimentalement. Le principal effet ce produit quand la vitesse de phase de l’onde de Lamb est proche de la vitesse du son dans le gaz. Les résultats suggèrent que les applications dans ce domaine seront très prometteuses. Les effets sur l’onde de Lamb de différents paramètres (densité, vitesse du son viscosité) d’une solution liquide sont étudiés. On montre que l’utilisation conjointe de A01 mode (fondamental du A0 mode) et du A03 mode (harmonique 3 DU A0 mode) permet de mesurer la densité et la vitesse du son. La densité étant connue, le S0 mode permet d’obtenir la viscosité

Abstract (sommario):
This chapter addresses the question of the universality of specific forms of intercorporeality. This detailed microethnographic study of a Wolof village in Northwestern Senegal describes how different senses—eye-gaze, hearing, and touch—are used in embodied interaction and how, in turn, participation in cultural interaction patterns shapes people’s senses. These patterns are notably different than they are in those Western societies about whose micro-interactions which we have reliable information. The chapter first analyzes the cooperative pounding of millet by four women, then, in the second part, examines in detail social interactions in which other intercorporeal resources than gaze, notably acoustic feedback signals and touch, are used to secure intersubjectivity. The third part shows how the experience and expression of emotions as well as basic cultural concepts such as the “person” are shaped by the specific Wolof forms of intercorporeality as they are lived in concrete interactional situations.

Abstract (sommario):
Abstract Conceptual design of a reversible micro-pump system is demonstrated by numerical simulations. Unsteady, incompressible Navier-Stokes equations in a moving boundary system are solved by ΝεκΤαr, a spectral element (high-order) algorithm employing an Arbitrary Lagrangian Eulerian (ALE) formulation on unstructured meshes. The performance of the micro-pump is evaluated as a function of the Reynolds number and the geometric parameters. The volumetric flowrate is shown to increase as a function of the Reynolds number. However, the efficiency of the micro-pump decreases with increased Reynolds number, due to the increased leakage effects.

Abstract (sommario):
The dynamics of viscous droplets near solid surfaces, especially micro-textured surfaces, and the interaction between them are of great importance in industrial applications, biochemical processes, and fundamental materials research on surface wettability. In this work, a three-dimensional spectral boundary element method has been employed to investigate the dynamics of a viscous droplet falling under gravity influence to micro-textured solid surfaces. The droplet size, in this study, is comparable to the size of the surface texture. The influences of the Bond number, relative size of the droplet with respect to the surface features, and the topological characteristics of the substrate on the droplet motion and deformation are investigated. The stress exerted on the substrate due to droplet motion is also explored.

Abstract (sommario):
Novel approaches are needed to support the creation of more open, inclusive, and self-sustaining R&I ecosystems in healthcare. This study analysed 3 European regions (Murcia ES), (Örebro SE), and (Republic of Cyprus CY), incorporating complementary approaches from Responsible Research and Innovation (RRI) and Research and Innovation Smart Specialisation Strategy (RIS3). The exercise entailed the identification of healthcare and innovation stakeholders and the characterisation of the policy landscape in each territory. Moreover, the strengths of the regional knowledge base was analysed by measuring the Revealed Comparative Advantage (RCA) indicator based on relatedness measurement, and by using micro-level fields analyses of scientific publications. This methodology allowed us to identify the fields and topics (strengths) that provide opportunities for innovation processes. Additional identification of social needs in the three territories showed profound differences regarding the alignment of the selected needs with respect to the regions’ capabilities. The results suggest that a timely direct interaction with territorial stakeholders can help in selecting the most promising innovation priorities that are based on local needs and knowledge. The process of interaction requires early engagement to support territorial ownership and is further reinforced by RRI policies in place.

Abstract (sommario):
Sliding friction on ice and snow is characteristically low at temperatures common on Earth’s surface. This slipperiness underlies efficient sleds, winter sports, and the need for specialized tires. Friction can also play micro-mechanical role affecting ice compressive and crushing strengths. Researchers have proposed several mechanisms thought to govern ice and snow friction, but directly validating the underlying mechanics has been difficult. This may be changing, as instruments capable of micro-scale measurements and imaging are now being brought to bear on friction studies. Nevertheless, given the broad regimes of practical interest (interaction length, temperature, speed, pressure, slider properties, etc.), it may be unrealistic to expect that a single mechanism accounts for why ice and snow are slippery. Because bulk ice, and the ice grains that constitute snow, are solids near their melting point at terrestrial temperatures, most research has focused on whether a lubricating water film forms at the interface with a slider. However, ice is extremely brittle, and dry-contact abrasion and wear at the front of sliders could prevent or delay a transition to lubricated contact. Also, water is a poor lubricant, and lubricating films thick enough to separate surface asperities may not form for many systems of interest. This article aims to assess our knowledge of the mechanics underlying ice and snow friction.

Abstract (sommario):
Substantial attention has been paid in recent years to the risk of maturity mismatch in emerging markets. Although this risk is microeconomic in nature, the evidence advanced thus far has taken the form of macro correlations. This paper empirically evaluates this mechanism at the micro level by using a database of over 3,000 publicly traded firms from fifteen emerging markets. The paper measures the risk of short-term exposure by estimating, at the firm level, the effect on investment of the interaction of short-term exposure and aggregate capital flows. This effect is (statistically) zero, contrary to the prediction of the maturity-mismatch hypothesis. This conclusion is robust to using a variety of different estimators, alternative measures of capital flows, and controls for devaluation effects and access to international capital. The paper finds evidence that short-term-exposed firms pay higher financing costs and liquidate assets at fire sale prices, but the paper does not find that this reduction in net worth translates into a drop in investment.

Abstract (sommario):
The quality and utilization of wheat is largely dependent upon the exact physical/chemical properties of the doughs made from flour/water mixtures. Among the wheat seed components most correlated with dough visoelastic parameters are the high-molecular-weight (HMW) glutenin subunits whose disulfide cross-linked macropolymer is critical for dough functionality. We have used the tools of molecular biology, wheat transformation, heterologous expression of HMW-glutenin subunits in bacteria, and dough micro-mixing experiments to examine some of the molecular basis of HMW-glutenin functionality. In addition, we have developed sets of modified and synthetic gene constructs and transgenic wheat lines that will allow further examination of the role of the HMW-glutenins. Among the results from this work is evidence that the HMW-glutenin repeat domain is directly related to dough properties, the demonstration that interaction between subunits is dependent upon domain presence but not order, a novel understanding of the restrictions on intra-vs inter-chain disulfide bonds, the demonstration that HMW-glutenin genes can be transformed into wheat for simultaneously high expression of the transgene and suppression of the endogenous genes, and the construction of a set of modified HMW-glutenins capable of being epitope tagged for studying polypeptide subcellular processing and the fate of HMW-glutenins in dough mixing experiments.

Abstract (sommario):
Based on literature review it was established that the use of augmented reality as an innovative technology of student training occurs in following directions: 3D image rendering; recognition and marking of real objects; interaction of a virtual object with a person in real time. The main advantages of using AR and VR in the educational process are highlighted: clarity, ability to simulate processes and phenomena, integration of educational disciplines, building an open education system, increasing motivation for learning, etc. It has been found that in the field of physical process modelling the Proteus Physics Laboratory is a popular example of augmented reality. Using the Proteus environment allows to visualize the functioning of the functional nodes of the computing system at the micro level. This is especially important for programming systems with limited resources, such as microcontrollers in the process of training future IT professionals. Experiment took place at Borys Grinchenko Kyiv University and Sumy State Pedagogical University named after A. S. Makarenko with students majoring in Computer Science (field of knowledge is Secondary Education (Informatics)). It was found that computer modelling has a positive effect on mastering the basics of microelectronics. The ways of further scientific researches for grounding, development and experimental verification of forms, methods and augmented reality, and can be used in the professional training of future IT specialists are outlined in the article.

Abstract (sommario):
Historically, the State of California assessed the environmental impacts of proposed developments based on how it was projected to affect an area’s level of service (LOS). However, as LOS focused on traffic delays, many agencies simply widened roads, which was an ineffective way to reduce greenhouse gas emissions (GHGs). With the passage of Senate Bill (SB)743 in 2013, LOS was replaced by Vehicle Miles Traveled (VMT) as a more appropriate metric by which to gauge the environmental impacts of proposed development. Additionally, SB 743 presented an opportunity for off-site VMT mitigation strategies through banking and exchanges– allowing multiple development projects to fund a variety of strategies to reduce VMT elsewhere in the city or region. While the shift from LOS to VMT has generally been lauded, concerns remain about how to apply SB 743 effectively and equitably. This study aimed to: 1) understand how local governments are addressing this shift toward VMT while ensuring equity, including its approaches to off-site VMT mitigation; and 2) evaluate the various built environment factors that impact VMT, which should be considered by local governments, using both qualitative and quantitative research designs. The study posited that both micro and macro level aspects of the built environment needed to be considered when evaluating the impacts of proposed development on VMT, not only to ensure higher accuracy VMT models, but also because of the potential equity implications of off-site mitigation measures. Using multiple linear regression, the study shows that macroscale built environment features such as land use, density, housing, and employment access have a statistically significant impact on reducing VMT (35%), along with transit access (15%), microscale features such as sidewalks, benches, and trees (13%), and income (6%). More notably, a four-way interaction was detected, indicating that VMT is dependent on the combination of macro and micro level built environment features, public transit access, and income. Additionally, qualitative interviews indicate that transportation practitioners deal with three types of challenges in the transition to VMT impact mitigation: the lack of reliable, standardized VMT measure and evaluation tools; the lack of a strong legal foundation for VMT as a component of the California Environmental Quality Act (CEQA); and the challenge of distributing off-site VMT mitigation equitably. Overall, findings support a nuanced, multi-factor understanding of the context in which new developments are being proposed, both in terms of modeling VMT, but also when considering whether offsite mitigation would be appropriate. The results of this study can help California ensure equitable VMT mitigation that better aligns with the state’s climate goals.
