Abstract:
Com o passar do tempo, a importância da formação inicial de professores tem sido cada vez mais reconhecida e valorizada. O Programa Institucional de Bolsa de Iniciação a Docência (PIBID), um programa onde os licenciandos tem a oportunidade de vivenciar a rotina escolar, tem importantes contribuições para essa formação. Neste trabalho faremos uma análise de própria prática numa escola do município de Lavras, onde, durante o estágio supervisionado, foram ministradas aulas de um bimestre letivo aos alunos do 2º ano do Ensino Médio. As atividades foram desenvolvidas a partir das experiências e conhecimentos adquiridos no PIBID de Biologia da UFLA. Cada aula foi relatada e, posteriormente analisada. Como resultados, encontramos temas considerados pela literatura como de uma formação de qualidade. Sendo assim, consideramos que as experiências do PIBID foram significativas para a formação da bolsista.Palavras-chave: Formação Inicial. PIBID. Estágio Supervisionado.

Abstract:
Com o surgimento de novas tecnologias notou-se que o perfil dos alunos vem se modificando. Sendo assim, torna-se fundamental ir além do método expositivo tradicional pautado no ensino que utiliza somente a sala de aula teórica. Acredita-se que a experimentação quando atrelada às aulas expositivas pode ser uma ferramenta de grande utilidade para o aumento do interesse dos alunos na disciplina de Química. Sendo assim, o presente trabalho teve como objetivo o desenvolvimento de uma prática experimental onde utilizou-se o sulfato de cobre (CuSO4.5H2O) para crescimento de cristais por nucleação. Tal prática abordou conceitos como os de cristalização, saturação, nucleação, e estrutura do cristal. O trabalho foi desenvolvido em duas turmas de segundo ano do curso técnico em química integrado ao ensino médio do Ifes - Vila Velha-ES, onde aplicou-se um questionário pré e pós-intervenção, utilizando a escala Likert, a fim de verificar se houve evolução na aprendizagem dos conteúdos envolvidos na experimentação.

Abstract:
O processo educacional brasileiro, vem desde a chegada dos portugueses ao Brasil, sofrendo mudanças, e sobretudo, a partir de 1985, com o processo de redemocratização, onde a educação sempre esteve como ponto de discussão nos grandes debates nacionais. Historicamente, a educação brasileira sempre esteve a serviço das elites, pois sempre esteve em seus objetivos formar mão de obra para os meios de produção capitalista, principalmente no que concerne a classe trabalhadora, houve e ainda há um grande investimento em cursos técnicos. Neste aspecto, desenvolveu-se ao longo dos tempos uma educação de cunho tecnicista que visa a domesticação do sujeito, ou seja, adestrá-lo ao Mercado. Este processo torna-se muito claro, se olharmos atentamente as propagandas do Ministério da Educação (MEC), veiculadas nos meios de comunicação, a questão dos cursos técnicos, por exemplo, onde os estudantes envolvidos no processo são treinados ou domesticados para produzir e não para pensar. O presente trabalho acadêmico visa demonstrar que ainda somos um país carente de uma educação que promova o sujeito em sua totalidade, isto é, a necessidade de se pensar o processo de ensino-aprendizagem a partir do contexto, da realidade na qual se encontra inserido, possibilitando-lhe o desenvolvimento de um pensamento crítico, assim como seu posicionamento frente as demandas apresentadas por este contexto. Nesta perspectiva e a partir de uma revisão bibliográfica, e tendo como referencial teórico, Paulo Freire, o presente artigo propõe a discussão de alguns elementos que perpassa a promoção de uma educação fundamentada na liberdade, na autonomia e na promoção da consciência crítica dos sujeitos envolvidos neste processo de ensino-aprendizagem, onde a escola possa ser um lugar, e não um instrumento de alienação, que promova a liberdade tendo em vista as transformações individuais, coletivas e sociais.

Abstract:
Inovação significa fazer algo novo, seu processo acontece quando simples possibilidades se tornam novas ideias reais e práticas. Embora esse processo já esteja incorporado há muito tempo na cultura organizacional, este continuamente se renova. Assim, interpretar a inovação e, sobretudo, condicioná-la às necessidades das empresas se torna uma grande necessidade para que estas se tornem competitivas nacional ou globalmente diante de qualquer cenário. O Marketing, por sua definição regular e mais abrangente, é uma técnica por onde se entrega valor para a satisfação de necessidades mercadológicas que possam interessar e atender demandas de consumidores gerais ou específicos por meio de produtos ou serviços criados, explorados e desenvolvidos. Uma de suas recentes ramificações se multiplica rapidamente e cada vez mais ganha a confiança de empresários e empreendedores, o Marketing Digital, cujas ações se voltam para atividades executadas de forma “computacional”, interligando pessoas e empresas, atraindo novos e potenciais negócios, criando relacionamentos e desenvolvendo identidades de marca em ambientes digitais. Este artigo propõe informar as possibilidades e potencialidades do Marketing Digital neste crítico período em que se vive uma pandemia. Assim, o principal objetivo dos autores foi analisar sua importância, inclusive, comparando diferenças do comércio eletrônico antes e durante a pandemia do COVID-19. A pesquisa se justifica pelo diferencial incorporado a esse tipo de marketing no enfrentamento da pandemia como uma poderosa ferramenta de “resistência” para as empresas e demais instituições que o utilizam. Adotou-se como metodologia as pesquisas explicativa, exploratória, bibliográfica e documental, onde excelentes resultados já foram percebidos e, dentre eles, já foi possível estabelecer que muitas empresas utilizadoras dos recursos do Marketing Digital sobreviveram, consolidaram atividades e ainda prestam excelentes serviços aos seus clientes.

O tema em questão diz respeito à análise da religião como meio de ressocialização dos presidiários, verificaremos se é um método eficaz, tendo em vista que, muitos presos ao deixarem a cadeia, se deparam com a mesma realidade de antes, onde não veem outra saída, a não ser a volta a criminalidade, diante disso, acredita-se que a religião tem se tornando um meio plausível para uma perspectiva de vida diferente a esses apenados. Em virtude da falha do sistema prisional, poucos são métodos realizados para ressocializar o indivíduo, visa-se com o presente estudo, reverter de maneira positiva a situação, e apresentar uma maneira satisfatória para uma nova percepção a estes encarcerados, concluímos que o sistema é falho a partir do momento que se encontra pouquíssimas obras sobre o respetivo tema em análise.

Abstract:
Le travail presente dans ce memoire porte sur une source d'ions micro-onde a effet de resonance ecr, multi-antenne, pour le traitement des grandes surfaces. Dans ce dispositif original un plasma micro-onde est cree a l'interieur d'une chambre de 20 cm. Le faisceau extrait est de 15 cm de diametre et la densite est de l'ordre du ma/cm 2. L'applicateur est un diviseur de puissance coaxial a n voies dans lequel les n = 20 antennes sont individuellement alimentees pour produire l'effet ecr au voisinage de leur extremite. Par ailleurs le confinement magnetique du plasma est realise par des aimants exterieurs. La separation de ces deux fonctions effet ecr et confinement donne la possibilite d'optimiser l'homogeneite du plasma et de realiser des sources de tres grand diametre (>50 cm). L'application du concept multi-antenne a une structure prototype de petit diametre a montre, dans un premiers temps, la validite de ce principe. Le choix de la structure finale a ete guide par des etudes a la fois, de simulation du champ electromagnetique a l'aide de la methode des elements finis (hfss) et egalement du champ magnetique statique par un code mis au point dans notre laboratoire. L'analyse du plasma est conduite en utilisant deux methodes de diagnostic : la sonde de langmuir et la spectroscopie d'emission. L'analyse du faisceau est realisee a l'aide d'un profilometre et d'un analyseur en energie mobile sur un diametre du faisceau. La comparaison de tous ces resultats nous a permis d'avoir une meilleure comprehension des phenomenes mis en jeu dans la decharge et de proposer un modele simple du fonctionnement de la source. Afin de neutraliser le faisceau d'ions, nous avons realise un canon a electrons egalement alimente par une micro-onde, mais sans utiliser l'effet ecr. Nous avons presente les differentes etapes de sa realisation. Le canon a ions et le neutraliseur forment donc un ensemble alimente exclusivement par une micro-onde a 2,45 ghz. Ce canon delivre un courant de 300 ma.

Abstract:
The idea to exploit the dispersive mechanism of surface waves as a probing tool for investigating subsurface structure was introduced about 30 years ago, and afterwards a very intense research field has developed. Currently many methods known generally as Surface Wave Methods exist, and are well established, most of them assuming layered or depth dependent ground models. In most cases the parallel layer assumption is correct because the soil structure is expected to negligibly depart from a layered structure at a typical surface testing scale for engineering and geotechnical purposes however to exploit the amount of information achievable, it is necessary to extend the research, relaxing at least one of the underlying model assumptions. Indeed in classical SWM’s, surface waves are assumed to be Rayleigh waves, this means that a parallel layered model has been implicitly assumed. As a consequence search for a soil model geometry other than the assumed one can only result in slight perturbations. The only possible deduction is that overcoming limitations of layered models requires to exploit P and S waves which are indeed general solutions of the elastodynamic problem. Geometry can then be retrived by a complete waveform inversion based on a forward model capable of successfully reproducing all of the features of the displacement field in presence of complex scattering phenomena. In this research effort an inversion approach has been introduced which exploits the Boundary Element Method as forward model. Such approach is appealing from a theoretical point of view and is computationally efficient. Although in the present work a monochromatic signal traveling in a system constituted by a layer over an half space was investigated, this method is suitable for any number of layers, and multi-frequency environments. The boundary element approach can be easily generalized to three-dimensional modeling; moreover viscoelasticity can be introduced by the elasticviscoelastic principle of correspondence. Finally BEM can be easily implemented for parallel computing architecture. Synthetic cases of high and low impedance Jump were investigated for typical SWM setups and a first example of application on real data was performed. Finally an elegant analytic form of the minimization flow named Adjoint Active Surfaces was obtained combining Computer Vision technique of Active surfaces and the Adjoint Field method.

Abstract:
L'objectif de cette thèse consiste en une modélisation numérique de l'interaction entre une onde électromagnétique émanant d'un radar d'observation aéroporté et une scène marine, c'est-à-dire une étendue d'eau de mer de caractéristiques physiques déterminées, portant éventuellement un ou plusieurs objets de composition métallique en surface, et d'évolution temporelle donnée. À cette fin, l'étude que nous avons menée fait appel à différentes techniques de modélisation numérique de la propagation ondulatoire électromagnétique : on s'est dans un premier temps penché sur l'utilisation de la technique des différences finies, puis sur le principe TLM (Transmission-Line Matrix), hérité du domaine des micro-ondes. Chacune des deux méthodes est appliquée au comportement de l'onde électromagnétique de manière locale, à proximité de la surface de mer uniquement, la simulation de la propagation en espace libre étant assurée par des moyens géométriques. Nous proposons dans un premier temps une brève étude critique de l'opportunité des méthodes numériques et de leur faisabilité en termes de demande en ressources de calcul notamment. Après cette évaluation théorique, un suivi du développement de l'implantation de la solution retenue est proposé. Nous présentons par la suite diverses applications de notre méthode de simulation : évaluation de la surface équivalente radar d'un patch de mer, dérivation de cartes de réflectivité, extension de l'évaluation de la surface équivalente radar à une grande zone de mer, mise en évidence de l'effet de la rugosité sur la puissance rétrodiffusée, simulation de l'observation par radar à synthèse d'ouverture d'un objet manufacturé sur une scène de mer, et comparaison de l'observation de scènes marines statiques et mouvantes. Le champ d'application des travaux présentés est large. Le travail de thèse s'inscrit dans le cadre du projet de développement MODENA, mené à l'échelle régionale bretonne, dont l'objectif est le développement d'outils de simulation d'acquisition radar au dessus de la surface de l'océan. À cet égard, les avancées théoriques et pratiques détaillées dans ce rapport de thèse offrent des perspectives intéressantes quant à la modélisation de telles observations
The aim of this thesis consists in numerically modelling the interaction between an electromagnetic wave emitted by an airborne observation radar and a maritime scene, i. E. An expanse of sea water of determined physical characteristics, possibly bearing one or several objects of metallic constitution on its surface, with a given temporal evolution. To this end, the study we carried out draws on different numerical modelling techniques for electromagnetic wave propagation: to begin with, the Finite-Differences Time-Domain (FDTD) technique was investigated, then the Transmission-Line Matrix method, inherited from the microwave domain, was studied. Each of the two methods is applied to the behaviour of the electromagnetic wave locally, in the vicinity of the sea surface only, the free space propagation simulation being undertaken through geometrical means. We propose a brief critical survey of the appropriateness of numerical methods and of their feasibility, particularly in terms of computation resources. After this theoretical study, we follow the development and implementation of the solution retained. We subsequently present several applications of our simulation method: radar cross section evaluation for small sea patches, derivation of reflectivity maps, extension of the radar cross section estimation to a large sea zone, yielding of the sea surface roughness influence upon the backscattered power, simulation of the synthetic aperture radar observation of a manufactured object in a sea scene, and comparison of the observation of static and moving sea scenes. The area of application of the work presented here is wide. The frame for the thesis is the MODENA development project, led at the Breton regional level, and whose objective is the development of radar acquisition simulation tools above the ocean's surface. In that respect, the theoretical and practical advances detailed in this thesis report widen the scope of the

Des melanges o#2/sih#4 et n#2o/sih#4 ont ete utilises pour deposer sio#2 dans une post-decharge micro-onde a basse temperature (<450c) et forte vitesse de depot. Dans un premier temps, une procedure de nettoyage in situ de la chambre de depot a ete mise au point. Il s'agit de graver l'oxyde depose sur les parois par un plasma radio-frequence de nf#3. Cette procedure n'influe pas sur les proprietes des films pourvu qu'une sequence de passivation de la chambre suive l'etape de nettoyage. Ensuite, la reactivite des deux gaz oxydants a ete comparee grace a l'etude des cinetiques de croissance et des proprietes des films (composition, contraintes. . . ) en faisant varier les parametres de depot (temperature, pression, rapport r des debits des gaz reactifs). L'etude cinetique a revele que le mecanisme de croissance est independant de la nature du melange gazeux utilise (o#2/sih#4 et n#2o/sih#4). La vitesse de depot est controlee par la diffusion d'une espece oxygenee dont la nature n'a pas ete determinee. En ce qui concerne les proprietes des films, les deux parametres principaux sont la temperature et le rapport r. Des couches denses, exemptes de liaisons si-h (ir), deposees a 7000 a/min, peuvent etre obtenues des 300c si r excede 20. Une etude detaillee de la composition (xps, rbs, nra, erda) a mis en evidence une influence significative de la nature du gaz oxydant (incorporation d'azote avec le melange n#2o/sih#4) et une relative independance de la stchiometrie vis-a-vis du rapport r. Enfin, le comportement electrique des oxydes a ete etudie en analysant les caracteristiques c(v) de capacites mos. Les films obtenus a partir de n#2o possedent des densites de charge elevees. Ce phenomene est relie a la presence d'azote et/ou a l'irradiation uv qui peut intervenir lors de la croissance.

Abstract:
Ce manuscrit est consacré à l’étude d’une torche plasma micro-onde fonctionnant à la pression atmosphérique pour la préparation de surfaces métalliques, plus particulièrement le dégraissage et l’oxydation de surface d’alliage aluminium Al2024 avant revêtement peinture d’une part et le décapage de TA6V avant soudage d’autre part. Des conditions optimales de fonctionnement sont dégagées grâce à une étude du comportement du plasma par spectroscopie d’émission optique et modélisation électromagnétique : le plasma généré par la torche est un gaz ionisant de température électronique Te = 7500 K et dont la densité d’espèces actives est favorisée par une puissance micro-onde l’ordre de 600 W, un débit de gaz plasmagène élevé et un positionnement proche de la base du jet. L’application de la torche aux cas particuliers du dégraissage et de l’oxydation de surface sont ensuite étudiés en terme d’énergie de surface et de profil de composition chimique en profondeur. Les résultats sont encourageants puisque le traitement plasma permet d’améliorer l’énergie de surface (elle passe de 32 mN/m à 72 mN/m) et de doubler l’épaisseur de la couche d’oxyde natif
This project is aimed at applying an atmospheric pressure microwave plasma torch to the treatment of metallic substrates. More precisely the applications are, on one hand, the oil removal from Al2024 samples and their surface oxidation before painting and on the other hand, cleaning TA6V substrates before welding. First of all optimal working conditions are defined thanks to investigations about the plasma behaviour by optical emission spectroscopy and electromagnetic calculations. This study puts the light on the fact that the plasma is ionizing, its electronic temperature is about 16500 K and the density of active species is favoured by a 600 W feeding power, a high plasma gas flow rate and a substrate location as close to the basis of the plasma jet as possible. The torch is quite efficient to remove oil from substrates and oxidise them in so far as the surface energy is improved (it increases from de 32 mN/m to 72 mN/m) and the native oxide layer thickness is doubled

Abstract:
Le collage direct est un procédé par lequel deux surfaces suffisamment planes et propres peuvent se coller sans ajout d'un adhésif. Le collage direct de surfaces structurées est souvent utilisé pour la fabrication de système mécanique microélectronique (MEMS), où une plaque de silicium avec des cavités est collée à une autre plaque de silicium. La fabrication de ces dispositifs est chère et il serait utile d'avoir une ligne directrice lors du dessin de structures afin de savoir à l'avance si le collage direct sera possible.Un modèle de simulation 2D pour le collage direct de deux substrats est développéet utilisé pour étudier l'influence des cavités sur la vitesse de propagation de l'ondede collage. Les prédications données par des simulations avec Comsol® sont en bonnecohérence avec les mesures expérimentales et une loi en 2 dimensions de la vitesse de collage est obtenue. Le collage de plaques parfaitement planes avec des cavités serait toujours possible. Les limitations lors du collage de vraies plaques sont dues au coût de l'énergie élastique pour déformer les plaques non parfaitement planes. Cette limite est atteinte facilement quand l'onde de collage doit traverser une tranchée, dans ce cas un dessin avec un petit guide de collage pour aider à traverser la cavité fonctionnera mieux. La taille de ce guide d'onde doit être choisis en considèrent la flèche de la plaque. En effet la seconde règle importante du dessin est de garder une surface de collage suffisante pour avoir plus d'énergie d'adhésion que le coût en énergie élastique dû à la déformation des plaques non parfaitement planes.L'énergie d'adhésion est un important paramètre du collage direct, car c'est l'énergie qui permet l'adhésion. Cette énergie d'adhésion est différente de l'énergie de collage la plus répandues qui est l'énergie requise pour séparer deux plaques précédemment collées. Dans cet ouvrage une méthode simple de mesure d'adhésion est proposée. Une mesure de l'évolution de l'énergie d'adhésion sur un temps long nous mène à proposer un mécanisme d'évolution lié à la formation de ponts capillaires entre des surfaces rugueuses
Direct bonding is a process by which two sufficiently flat and clean surfaces can bond to each other without any added adhesive layer. Direct bonding of patterned surfaces is often used for the fabrication of Micro-Electro-Mechanical Systems (MEMS), where a silicon wafer with cavities is bonded to a plain wafer. The fabrication of these devices is expensive and it would be useful to have guidelines when designing knew devices to know in advance if direct bonding will be possible.A 2D simulation model of the direct bonding of two substrates is developed and usedto study the influence of the cavities on the bonding wave velocity. The prediction of the simulation run with Comsol® are in good coherence with the experimental measures and a 2D law of the bonding velocity is obtained. The bonding of perfectly flat wafers with cavities should always be possible. Limitations to the bonding of real wafers are due to the elastic energy cost of deforming the non perfectly flat wafers. This limit is reached easily when the bonding wave must cross a trench, so a design with a small bonding guide to help cross the cavity will work best. The width of this wave guide should be chosen by considering the bow of the wafer. Indeed the second important design rule is to keep a bonding area big enough to have more adhesion energy than the elastic energy cost due to non flat wafers deformation.The adhesion energy is an important parameter of the direct bonding, as it is theenergy that drives the adhesion. This adhesion energy is different from the more widely known bonding energy which is the energy needed to separate two previously bonded wafers. In this work a simple method to measure the adhesion is proposed. Long time measurement of the evolution of the adhesion energy lead us to propose a mechanism for its evolution linked to the formation of capillary bridges between rough surfaces

Abstract:
La diffraction d'une onde électromagnétique par des surfaces diélectriques ou conductrices rugueuses est étudiée par une méthode différentielle. Le formalisme utilisé repose essentiellement sur la forme covariante des équations de Maxwell écrites dans un système de coordonnées non orthogonales adapté a la géométrie du problème. A partir de ce formalisme deux méthodes sont proposées : dans la première on considère la déformation comme une fonction perturbatrice et les solutions sont données sous une forme analytique simple. Dans la seconde, le traitement est plus rigoureux. Le problème est ramené à la résolution d'un système intégro-différentiel linéaire à coefficients constants. Par suite on est conduit à la recherche de valeurs et de vecteurs propres d'une matrice caractéristique a la fois du milieu et de la forme de la surface diffractante

Abstract:
L'estimation et le suivi des ressources en eau des surfaces continentales aux niveaux régional et global est essentielle pour la gestion du bilan hydrique, particulièrement dans le contexte des changements climatiques et anthropiques. Ils couvrent un large éventail de thèmes et de domaines, incluant la caractérisation des ressources en eau à l'échelle du bassin, la modélisation hydrologique ainsi que la prévision et la cartographie des inondations. Dans ce contexte, la caractérisation des états de surface, en tant que paramètres d'entrée dans les modèles hydrologiques, est essentielle pour obtenir une meilleure précision de la simulation, qui est liée à la précision prévisionnelle des débits des cours d'eau et le suivi des sécheresses et des inondations. L'estimation de la teneur en eau des surfaces continentales, incluant l'état hydrique du sol et les niveaux des surfaces couvertes d'eau, est particulièrement nécessaire pour une description précise des processus hydrologiques et plus généralement du cycle de l'eau sur les surfaces continentales. Afin de mieux comprendre les processus hydrologiques, l'influence humaine (l'effet anthropique) sur le cycle de l'eau nécessite une évaluation fine. Elle est particulièrement liée à la gestion de l'irrigation et la construction de barrages. L'objectif de la thèse était d'améliorer l'estimation des ressources en eau et une meilleure caractérisation des interventions anthropiques à travers l'utilisation de nouveaux capteurs satellitaires multi-configurations du programme européen Copernicus. Avec le développement de la technologie de télédétection spatiale, et plus particulièrement avec l'arrivée des constellations Sentinel (Sentinel-1, 2, 3) à haute résolution spatiale et temporelle, il existe un meilleur outil pour estimer les états des surfaces continentales. Ce travail de thèse comprend principalement deux priorités liées à des interventions humaines dans le cycle hydrologique:la cartographie de l'irrigation en tant que action humaine liée directement à l'humidité du sol et le forçage des barrages dans un modèle de simulation de rivière en tant qu'application liée à l'estimation du niveau de l'eau libre. Un premier axe de recherche a été basé sur une analyse statistique des données SAR Sentinel-1 pour caractériser l'état hydrique du sol. Deux méthodes ont été développées pour estimer ce paramètre avec une résolution spatiale de 100 m. Elles sont basées sur des approches de détection de changement à partir des données Sentinel-1 acquises en polarisation VV (verticale-verticale), combinées aux données optiques Sentinel-2 pour corriger les effets de la végétation
The estimation of the water resources of the continental surfaces at a regional and global scale is fundamental for good water resources management. This estimation covers a wide range of topics and fields, including the characterisation of soils and water resources at the basin scale, hydrological modelling and flood prediction and mapping. In this context, the characterisation of the states of the continental surface, to obtain better input parameters for hydrological models, is essential to improve the precision in the simulation of flows, droughts, and floods. The estimation of the water content in the system, including the different water bodies and the free water in the soil, is especially necessary for a precise description of the hydrological processes and, in general, of the water cycle on the continental surfaces. To better characterise hydrological processes, human interventions cannot be neglected. Humans influence the water cycle, mainly through irrigation and the construction of reservoirs, which must be correctly quantified. The objective of the thesis is the improvement of the remote estimation of water resources, including the quantification of human factors, using several sensors recently launched, taking advantage of recent developments in remote sensing technology. With the arrival of the Sentinel constellations (Sentinel-1, 2, 3), we have better tools to estimate water resources, including human impacts, with greater precision and coverage. This thesis consists mainly of two parts where human interventions in the water cycle are considered: irrigation cartography (as an application of soil moisture), and the forcing of reservoirs in hydrological simulations (as an application of altimetry). Firstly, soil moisture is estimated from the statistical analysis of Sentinel-1 SAR data. Two methodologies are developed to obtain soil moisture with a spatial resolution of 100 m based on the interpretation of Sentinel-1 data collected with the VV polarization (vertical-vertical), which is combined with optical data of Sentinel-2 for the analysis of the effects of vegetation. Secondly, irrigation is mapped under various meteorological conditions, including high spatial and temporal resolution

Abstract:
The application of aspherical surfaces in camera lens started over twenty years ago. Many people suggested and executed many ideas regarding the application of aspherical surfaces. One of the ideas is that the application decreases the value of the F No. The example of the applications is a pick-up-lens that picks up information on a disk using the optical method. In this paper, we discuss the application of aspherical surfaces in wide angle lenses with a large back focus for reflex cameras. The application mainly corrects distortion in the lens designs. An object of the present paper is to show an inverse telescopic wide angle lens capable of simplifying the lens configuration thereby reducing the dimension of lens, correcting various aberrations in satisfactory manner, and still extending the back focus.

Abstract:
By using a number of aspheric surfaces in a novel afocal arrangement a new binocular system has been designed which avoids the use of erecting prisms and provides a very wide horizontal field of view. The method uses spherical reflecting surfaces to re-fold the light path so that the field curvature is substantially corrected. This allows larger than normal eyepiece lenses giving a greater eye-relief in spite of the wide field of view.

Full text
Abstract:
The localization of classical waves, like electromagnetic or acoustic ones, has been widely studied for a few years [1]. For one- or two-dimensional systems, the localization of propagating modes is theoretically predicted at any non vanishing disorder. For instance, surface plasmon polaritons (SPP), which are extended modes of flat metallic surfaces, become localized in the presence of random roughness [2,3]. Localization of SPP on rough surfaces has important contributions to surface-enhanced phenomena [2] and gives birth to the phenomenon of enhanced backscattering for shallow surfaces [3]. But it seems that no experimental confirmation exists yet [1]. To my knowledge, no direct numerical evidence of localization has neither been published, since only backscattering peaks, considered as a signature of localization, are exhibited. Thanks to the model achieved in our laboratory [4], it is now possible.

Abstract:
A Clegg Impact Tester, also known as a Clegg Hammer, is a portable device invented by Dr. Baden Clegg to assess surface shock absorption and bearing capacity. It measures the strength of soils, aggregates, and synthetic materials for roads and sports surfaces. The tester consists of a compaction hammer, guiding tube, and piezoelectric accelerometer. It quantifies a surface's ability to withstand structural load and offers insights into strength, stiffness, and stability. The hammer is dropped from a specific height, and its impact is measured. Clegg Impact Testers are used for various applications, including road quality, turf safety, athletic tracks, and stall surfaces. Factors to consider when choosing one include hammer weight, readout range, power source, and additional features.

Abstract:
Review question / Objective: Does the bioactive surface of titanium dental implants, based on biomolecules, influence osseointegration?. The aim of our study was to evaluate the role and efficacy of bioactive surfaces in osseointegration. Our review study limited the research interest to titanium dental implants coated with a biomolecule, i.e., an organic molecule produced by a living organism. Condition being studied: In recent years, much attention has been paid to topographical modifications of dental implant surfaces, as well as to their coating with biologically active substances.a bioactive surface is one capable of achieving faster and higher quality osseointegration, shortening waiting times and solving situations of poor bone quality. Molecules that can be applied for bioactive purposes include bioceramics, ions and biomolecules. Collagen and bone morphogenetic protein have been suggested as bone stimulating agents. Biofunctionalization of the implant surface with a biomimetic active peptide has also been shown to result in a significant increase in bone-to-implant ratios and an increase in peri-implant bone density.

Full text
Abstract:
People with food allergy must avoid eating the foods they are allergic to as they may react to very small amounts of such foods. Allergenic food left on surfaces or equipment could contaminate another food that is also prepared using the same surface or equipment. Cleaning of surfaces and equipment is therefore one way that businesses try to prevent contamination with food allergens. Food businesses let people know that food could be contaminated with allergens using Precautionary Allergen Labelling (PAL) such as ‘may contain’ statements. Evidence gathered from previous food industry consultations shows that there is uncertainty around the effectiveness of allergen cleaning which is a barrier to effective use of PAL.

Full text
Abstract:
Canada 1 Water is a 3-year governmental multi-department-private-sector-academic collaboration to model the groundwater-surface-water of Canada coupled with historic climate and climate scenario input. To address this challenge continental Canada has been allocated to one of 6 large watershed basins of approximately two million km2. The model domains are based on natural watershed boundaries and include approximately 1 million km2 of the United States. In year one (2020-2021) data assembly and validation of some 20 datasets (layers) is the focus of work along with conceptual model development. To support analysis of the entire water balance the modelling framework consists of three distinct components and modelling software. Land Surface modelling with the Community Land Model will support information needed for both the regional climate modelling using the Weather Research &amp; Forecasting model (WRF), and input to HydroGeoSphere for groundwater-surface-water modelling. The inclusion of the transboundary watersheds will provide a first time assessment of water resources in this critical international domain. Modelling is also being integrated with Remote Sensing datasets, notably the Gravity Recovery and Climate Experiment (GRACE). GRACE supports regional scale watershed analysis of total water flux. GRACE along with terrestrial time-series data will serve provide validation datasets for model results to ensure that the final project outputs are representative and reliable. The project has an active engagement and collaborative effort underway to try and maximize the long-term benefit of the framework. Much of the supporting model datasets will be published under open access licence to support broad usage and integration.
