Abstract:
Electromagnetism is expressed from two basic postulates. They are light invarianceand charge conservation. At this work one extends the Maxwell scenario from macroscopic to microscopic electromagnetism by following the elementary particles electric charge microscopic behavior. It yields a triune electric charge interrelationship. Three charges {+, 0, −} be exchanged through a vector bosons quadruplet. It is called Four Bosons Electromagnetism. A systemic EM physics appears to be understood. Maxwell photon is not enough for describing the microscopic electric charge physics. An extension for electromagnetic energy is obtained. The fields quadruplet {Aµ, Uµ, Vµ±} are the porters of electromagnetic energy. They are the usual photon Aµ, massive photon Uµ and two charged photons Vµ±, A new understanding on EM phenomena has to be considered. A set determinism based on granular and collective fields is developed. A space-time evolution associated to a whole.Conservation laws are studied. The EM phenomena is enlarged to three charges interchanges to {+, 0, −}. Two novelties appear. New features on nonlinear fields acting as own sources and on electric charge physics. Properties as conservation, conduction, transmission, interaction are extended to a systemic electromagnetism. A whole conservation law for electric charge emerges from three charges interwoven. Electric charge has a systemic behavior. Although there is no Coulomb law for zero electric charge, the Four Bosons Electromagnetism contains an EM energy which provides a neutral electromagnetism. Particles with zero charge {Aµ, Uµ} are carrying EM energy. Another consideration is on EM energy being transported by four nonlinear fields. A new physicality appears. The abelian nonlinearity generates fields charges. Fields are working as own sources through mass terms, trilinear and quadrilinear interactions, spin couplings. Consequently the photon is more than being a consequence from electric charge oscillations. It is able to generate its own charge. Introduce the meaning of photonics.Thus, electric charge is no more the isolate electromagnetic source. There are another conservation laws. Fields sources appear through corresponding equations of motion, Bianchi identities, energy-momentum, Noether laws and angular momentum conservation laws. They move EM to a fields charges dependence. Together with electric charge they carrythe electromagnetic flux. Supporting the Ahranov-Bohm experiment of potential fields as primitive entities.

Abstract:
Based on light invariance and electric conservation a four bosons electromagnetism is proposed. It enlarges the electric charge conservation beyond displacement current and Dirac charge to a new physical situation where the electromagnetic phenomena is mediated by the usual photon plus a massive photon and two additional charged vector bosons.Considering the enlarged abelian gauge symmetry U(1) SO(2) transforming under a same gauge parameter a non-linear electromagnetism involving four bosons is introduced. It deploys a Lagrangian containing massless, massive and charged elds with three and four vector bosons interactions. The corresponding Noether's relations and classical equations of motion are studied. They provide a whole dynamics involving granular, collective terms through antisymmetric and symmetric sectors. It develops a new photon equation which extends the Maxwell's one. Self interacting photons are obtained.A four boson electromagnetic ux is derived. It expresses an electromagnetism transfering 4Q = 0 and j4Qj = 1, not more limited to just a massless photon. There is a new electromagnetic owing to be understood, where aside of electric charge conservation, it appears a neutral electromagnetism. There are six neutral electromagnetic charges beyond electric charge as consequences from non-linearity. Two are derived from the second Noether identity and four from variational continuity equations. An electromagnetic ux being conducted by a whole physics is generated. Based on elds set, it develops a determinism under the meaning of directive and circumstance. Interpreting that, light invariance concises the photon as directive, the photon becomes a whole maker. It assumes the symmetry command which will control the conservations laws and opportunities. Consequently, one combines the symmetry equation derived fromNoether theorem with the four equations derived from variational principle, and an effective photon equation is obtained. A kind of Navier-Stokes electromagnetic ow is derived. It yields a four bosons electromagnetism preserving electric charge conservation plus introducting the meaning of chance through symmetry management.

Abstract:
We argue that the charge fractionalization in quarks has a hidden topological character related to a broken [Formula: see text] symmetry between integer-charged bare quarks and leptons. The mechanism is a tunneling process occurring in time between standard field configurations of a pure gauge form with different topological winding numbers associated with integer-charged bare quarks in the far past and future. This transition, which nonperturbatively normalizes local bare charges with a universal accumulated value, corresponds to a specific topologically nontrivial configuration of the weak gauge fields in Euclidean spacetime. The outcome is an effective topological charge equal to the ratio between baryon number and the number of fermion generations associated with baryonic matter. The observed conservation of baryon number is then related to the conservation of this bookkeeping charge on quarks. Baryon number violation may only arise through topological effects as in decays induced by electroweak instantons. However, stability of a free proton is expected.

Ren, Bo. "Who was in charge of the water conservation? : investigation of water conservation and management in the upper reaches of the Huai, 1912-1949." Thesis, University of Nottingham, 2017. http://eprints.nottingham.ac.uk/41089/.

Full text
Abstract:
This thesis examines water conservation in the upper valley of the Huai River in Anhui Province, close to the border between north and south China, during the Republic of China (ROC) era (1912-1949). Two main flood relief and water conservation projects are studied in detail. In order to gain a deeper and broader understanding of water conservation policies and practices in China during that period, additional comparative studies were undertaken of two water conservation projects in the lower areas of the Yangtze River in south and northwest China. The main question addressed in the thesis is: What are the key factors affecting the conservation and management of water in China during the ROC era? A further aim of the thesis is to reveal the inter-relationships between water conservation and ROC government policies, and the influence of grass roots actors and international powers in that period. This thesis includes a review of the literature on environmental history, in particular the history of water conservation. For the empirical investigation, a multi-disciplinary, mixed method was adopted, combining the study of historical documents and fieldwork in a series of detailed case studies. Firstly, this study investigates the relief work project in the upper area of the Huai River. The work and the lives of peasant labourers in a water conservation project, including their cooperation and conflicts with upper class engineers and officials are considered in order to provide a vivid and thorough exploration of the worksite. Secondly, the thesis describes and analyses the relationships between various groups (including engineers, the gentry, residents and officials of the Anfengtang Pond community), through a series of stories that highlight their activities, roles and priorities within water conservation and management initiatives. Thirdly, the thesis considers the history of the Lotus Polder and the story of the Jinghui Channel. Fourth, it explores the relationship between international politics and water conservation in the ROC to explain how modern culture and industry penetrated an old water conservation community. The interplay and influence of a wide variety of factors that affected water conservation in the ROC era, such as land policies, economic situation, national finance, wars, traditions and western factors, are addressed and analysed in this thesis.

Abstract:
Wireless sensor networks suffer from limited power resources. Therefore, managing the energy constraints and exploring new ways to minimize the power consumption during the operation of the nodes are critical issues. Conventional MAC protocols deal with this problem without considering the internal properties of the sensor nodes’ batteries. However, recent studies about battery modeling and behaviour showed that the pulsed discharge mechanism and the charge recovery effect may have a significant impact on wireless communication in terms of power saving. In this thesis we propose two battery-aware MAC protocols that take benefit of these factors to save more energy and to prolong the lifetime of the nodes/network without affecting the throughput. In both protocols we measure the remaining battery capacity of the node and use that measurement in the back-off scheme. The first protocol gives the nodes with higher remaining battery capacity more priority to access the medium, while the other one provides more medium access priority to the nodes with lower remaining battery capacity. The objective is to investigate, through simulations, which protocol reduces the power consumption of the nodes, improve the lifetime of the network, and compare the results with the CSMA-CA protocol.

Abstract:
Les progrès technologiques réalisés ces dernières années ont permis le développement de nouveaux types de capteurs dotés de moyens de communication sans fil, peu onéreux et pouvant être configurés pour former des réseaux autonomes. Les domaines d'application sont nombreux : domotique, santé, domaine militaire ou bien encore surveillance de phénomènes environnementaux. Les limites imposées sont la limitation des capacités de traitement, de stockage et surtout d'énergie. La liberté laissée à l'implantation est forte et impose de concevoir complètement l'infrastructure, les mécanismes et les protocoles en fonction de l'application visée. Dans cette thèse, nous nous sommes tout d'abord focalisés sur des réseaux de petites tailles. Nous avons conçu une solution protocolaire "Placide" pour le suivi de la chaîne du froid proposée dans le cadre du projet ANR-CAPTEURS. L'originalité première de la solution repose sur l'absence d'infrastructure et de Station de Base. Elle est composée de protocoles performants fondés sur la formation d'un anneau virtuel entre les noeuds, auto-organisants et très économes en énergie. Le second axe est dédié à une étude expérimentale de la qualité du lien.L'objectif est double. Nous souhaitions tout d'abord étayer certaines hypothèses effectuées dans la première partie du travail. Il s'agissait ensuite de proposer des protocoles et des algorithmes fondés sur la qualité du lien. Nous nous sommes focalisés sur la variation de la qualité du lien en fonction de la distance entre les noeuds et de la puissance de transmission. Par la suite, l'impact de la qualité du lien sur la topologie du réseau a été étudiée. Les retours d'expérience sont importants quant à la compréhension des facteurs affectant la durée de vie du réseau. La dernière contribution concerne l'exploitation de ces observations en proposant des stratégies de partage decharge. Notre idée est que des protocoles très réduits et des mécanismes simples peuvent être mis en oeuvre pour le routage. Nous illustrons ces principes au travers d'exemples pour lesquels nous montrons la supériorité de ces solutions par rapport à des routages de type plus court chemin
Technological advances during the last few years allowed the development of new and cheap sensors equiped with wireless communication which can be configured to form autonomous networks. The application areas for wireless sensor networks (WSN) are various: home automations, health care services, military domain, and environment monitoring. The imposed constraints are limited capacity of processing, storage, and especially energy. In addition, implementing WSN solutions is highly open and requires that the infrastructure, the mechanisms and the protocols should be completely designed based on each specific application.In this thesis, we first focused on small networks. We designed « Placide », a protocol stack solution for cold chain monitoring proposed within the ANR-CAPTEURS project. The first originality of this solution is based on the absence of infrastructure and base stations. « Placide » is composed of self-organizing and energy-efficient protocols based on a virtual ring construction between nodes. The second topic is devoted to an experimental study on Link Quality Indicator (LQI). There are two main objectives. Firstly, we want to endorse our precise assumptions of the first part of the work. Secondly, our poposed link quality based protocols and algorithms willbe described. We focused on LQI variations according to distance between nodes and transmission power.Thereafter, the impact of LQI on the network topology has been studied. Feedbacks are important to understand which factors affect the network lifetime. The last contribution relates to the use of these observations by proposing load balancing strategies. Our idea is that very reduced protocols and simple mechanisms can be used in routing protocols. We illustrate these principles through simple examples where we show the superiority of these solutions compared to standard routing like shortest path for example

Abstract:
L'anthropisation croissante et les changements globaux entrainent de nombreuses perturbations dans l'environnement conduisant à la dégradation, et même à la destruction d'habitat. Le modèle allostatique proposé par McEwen et Wingfield en 2003 permet de mieux appréhender les relations entre physiologie et réponses démographique dans le cadre de la physiologie de la conservation. A travers des approches expérimentales en milieux controlé et semi-naturel nous avons testé l'effet de d'un stress chronique sur les changements des traits d'histoires de vie et les paramétres physiologique chez le lézard vivipare (Zootoca vivipara). Nous discutons de la caractérisation de la charge allostatique et des effets à court terme et long terme d'un stress chronique et l'utilisation de la charge allostatique comme indicateur de la dégradation de l'habitat. Ce travail pourra être utilisé afin de mieux comprendre et prédire la dynamique des populations naturelles soumises aux changements globaux
Increasing anthropogenic and global changes are causing many disturbances in the environment leading to degradation and even destruction of habitat. The allostatic model proposed by McEwen and Wingfield in 2003 provides a better understanding of the relationships between physiology and demographic responses within the framework of conservation physiology. Experimental approaches in controlled and semi-natural environments have tested the effect of chronic stress on changes in life histories and physiological parameters in the viviparous lizard (Zootoca vivipara). We discuss the characterization of allostatic charge and the short-term and long-term effects of chronic stress and the use of allostatic charge as an indicator of habitat degradation. This work can be used to better understand and predict the dynamics of natural populations subjected to global changes

Abstract:
Une nouvelle méthode est proposée pour la simulation des plasmas utilisant le modèle cinétique qui couple les équations de Vlasov pour la distribution des particules et de Maxwell pour la contribution des champs électromagnétiques. Cette méthode est semi-Lagrangienne, elle utilise une grille de l'espace des phases et se sert des caractéristiques de l'équation de Vlasov. Ces caractéristiques sont suivies en avançant dans le temps, ce qui permet plusieurs avantages par rapport à la méthode classique. Déjà, cette méthode est explicite, ce qui permet une montée en ordre facilitée qui peut offrir davantage de stabilité, et la possibilité de construire des schémas qui conservent la charge en utilisant ses similitudes avec les méthodes PIC. Ceci est fondamental pour s'assurer que les solutions calculées sont bien physiques.

Abstract:
Un certain nombre d'applications électrostatiques, notamment les dépoussiéreurs électrostatiques, mettent en oeuvre le phénomène de décharge couronne dans les gaz à partir d'électrodes ayant une forte courbure. Ces électrodes injectent des charges dans le gaz et la charge d'espace qui en résulte modifie la distribution du champ électrique. Le but de notre travail a été de développer un code numérique pour déterminer les distributions de champ électrique et de densité de charge dans la configuration lame-plan, la création de charge se faisant par effet couronne sur le bord de la lame.
Nous utilisons la méthode des éléments finis MEF pour résoudre l'équation de Poisson et la méthode des caractéristiques MC pour résoudre l'équation de conservation de la charge. Les deux équations couplées sont résolues par approximations successives en redéfinissant le maillage structuré à chaque itération pour éliminer la diffusion numérique. La redéfinition du maillage structuré est la partie la plus importante du travail. L'algorithme converge bien pour différentes distributions de la charge définies sur la lame injectrice. Les solutions numériques obtenues pour une loi d'injection imposée sur la lame plate donnent des résultats en très bon accord avec les mesures de densité de courant sur l'électrode plane d'un dispositif lame-plan.

Abstract:
Alors que nous faisons face à une crise biologique majeure, acteurs institutionnel et ONGs exhortent les entreprises à s’engager pour enrayer cette érosion écologique. L’objectif de la thèse est d’analyser, évaluer et faire évoluer la contribution potentielle des entreprises à la conservation de la biodiversité dans le cadre de leur responsabilité sociétale (RSE).Un cadre d’analyse est développé pour évaluer la prise en charge par une entreprise de ses responsabilités écologiques en termes de moyens – les initiatives RSE a priori favorables à la biodiversité mises en œuvre – et de résultats – la compatibilité des activités de l’entreprise avec la conservation de la biodiversité. Après avoir caractérisé les initiatives RSE à partir de l’étude d’engagements d’entreprises endossés comme contributions à la Stratégie nationale pour la biodiversité, une méthode est proposée pour détecter si les activités d’une entreprise sont écologiquement non-durables. Le postulat est que le respect des capacités de charge des écosystèmes est un prérequis à la conservation effective de la biodiversité. Cette méthode, adaptée de l’évaluation environnementale absolue de la durabilité, est appliquée, dans le cadre de deux projets de recherche-intervention, au portfolio alimentaire du Groupe Casino et au cycle de vie de deux installations de stockage de déchets dangereux de SARP Industries. Des orientations stratégiques visant à éviter-réduire-compenser les pressions non durables sont proposées. Soulignant l’importance de renforcer la prise en charge des pressions étendues, cette thèse ouvre plus largement des perspectives pour les secteurs d’activité et les politiques publiques
As we are experiencing a major biological crisis, institutional actors and NGOs are calling on businesses to engage efforts aiming at halting biodiversity loss. The objective of the thesis is to analyze and evaluate the potential contribution of corporate social responsibility (CSR) to biodiversity conservation.A framework is developed to analyze to which extent a company takes in charge its ecological responsibilities. After characterizing CSR initiatives based on the case study of business commitments to contribute to the French National Biodiversity Strategy, a method is proposed to test whether business activities exert unsustainable pressures on ecosystems. It is assumed that compatibility with ecosystems’ carrying capacities is a prerequisite for effective biodiversity conservation. This method, adapted from the “absolute environmental sustainability assessment” (AESA) approach, is applied in the context of research-intervention projects to the food portfolio of the mass-market retailer Groupe Casino and to the life cycle of two facilities of SARP Industrie specialized in the disposal and storage of hazardous waste. The comparison of the company’s environmental footprints with the ecological constraints is used to draw a comprehensive strategy based on the mitigation hierarchy. As our results highlight the opportunity to strengthen the management of extended pressures through CSR, possible implications for sectors and public policies are discussed

Full text
Abstract:
Cette thèse propose l’étude d’une méthode numérique permettant de simuler un plasma. On considère un ensemble de particules, dont le mouvement est régi par l’équation de Vlasov, et qui est sensible aux forces électromagnétiques, qui proviennent des équations de Maxwell. La résolution numérique des équations de Vlasov-Maxwell est réalisée par une méthode Particle In Cell (PIC). La résolution des équations de Maxwell nécessite un maillage suffisamment fin afin de modéliser correctement les problémes multi-échelles que nous souhaitons traiter. Cependant, mailler finement tout le domaine de calcul a un coût. La nouveauté de cette thèse est de proposer un solveur PIC sur des maillages cartésiens localement raffinés, des maillages non conformes, afin de garantir la bonne modélisation du phénomène physique et d’éviter une trop forte pénalisation des temps de calcul.Nous utilisons une méthode Galerkin Discontinue en domaine temporelle (GDDT), qui offre l’avantage d’être d'une grande flexibilité dans le choix du maillage et qui est une méthode d’ordre élevé. Un point fondamental dans l’étude des solveurs PIC concerne le respect de la conservation de la charge. Nous proposons deux approches afin de traiter cet aspect. La première concerne les méthodes utilisant un système de Maxwell augmenté, dont la nouveauté a été de les étendre aux maillages non conformes. La seconde approche repose sur une méthode originale de pré-traitement du calcul du terme source de courant
This thesis deals with the study of a numerical method to simulate a plasma. We consider a set of particles whose displacement is governed by the Vlasov equation and which creates an electromagnetic field thanks to Maxwell equations. The numerical resolution of the Vlasov-Maxwell system is performed by a Particle In Cell (PIC) method. The resolution of Maxwell equations needs a sufficiently fine mesh to correctly simulate the multi scaled problems that we have to face. Yet, a uniform fine mesh of the whole domain has a prohibitive cost. The novelty of this thesis is a PIC solver on locally refined Cartesian meshes : non conforming meshes, to guarantee the good modeling of the physical phenomena and to avoid too large CPU time. We use the Discontinuous Galerkin in Time Domain (DGTD) method which has the advantage of a great flexibility in the choice of the mesh and which is a high order method. A fundamental point in the study of PIC solvers is the respect of the charge conserving law. We propose two approaches to tackle this point. The first one deals with augmented Maxwell systems, that we have adapted to non conforming meshes. The second one deals with an original method of preprocessing of the calculation of the current source term

These issues emerge in significant narrative pages such as Non luogo a procedere (2015), which is a lucid and disenchanted consideration of the history of the city, moved by a strong ethical charge, and Tempo curvo a Krems (2019), which is a profound synthesis of the many aspects of Magris’ fictional and critical work.

Abstract:
Elucidating the transient characteristics of a polymer electrolyte fuel cell in consideration of its applications, such as electric vehicles, is an important step in its development. In this study, we created a mathematical model to predict the transient behavior of a unit-PEFC, analyzed the model numerically, and compared the results with experimental results. Consequently, we elucidated that the transient behavior of a PEFC is summarized by two physical phenomena: (1) water redistribution in the polymer electrolyte membrane, (2) the discharge/charge of electric double layer capacitance.

Wright, Kirsten. Collecting Plant Phenology Data In Imperiled Oregon White Oak Ecosystems: Analysis and Recommendations for Metro. Portland State University, March 2020. http://dx.doi.org/10.15760/mem.64.

Full text
Abstract:
Highly imperiled Oregon white oak ecosystems are a regional conservation priority of numerous organizations, including Oregon Metro, a regional government serving over one million people in the Portland area. Previously dominant systems in the Pacific Northwest, upland prairie and oak woodlands are now experiencing significant threat, with only 2% remaining in the Willamette Valley in small fragments (Hulse et al. 2002). These fragments are of high conservation value because of the rich biodiversity they support, including rare and endemic species, such as Delphinium leucophaeum (Oregon Department of Agriculture, 2020). Since 2010, Metro scientists and volunteers have collected phenology data on approximately 140 species of forbs and graminoids in regional oak prairie and woodlands. Phenology is the study of life-stage events in plants and animals, such as budbreak and senescence in flowering plants, and widely acknowledged as a sensitive indicator of environmental change (Parmesan 2007). Indeed, shifts in plant phenology have been observed over the last few decades as a result of climate change (Parmesan 2006). In oak systems, these changes have profound implications for plant community composition and diversity, as well as trophic interactions and general ecosystem function (Willis 2008). While the original intent of Metro’s phenology data-collection was to track long-term phenology trends, limitations in data collection methods have made such analysis difficult. Rather, these data are currently used to inform seasonal management decisions on Metro properties, such as when to collect seed for propagation and when to spray herbicide to control invasive species. Metro is now interested in fine-tuning their data-collection methods to better capture long-term phenology trends to guide future conservation strategies. Addressing the regional and global conservation issues of our time will require unprecedented collaboration. Phenology data collected on Metro properties is not only an important asset for Metro’s conservation plan, but holds potential to support broader research on a larger scale. As a leader in urban conservation, Metro is poised to make a meaningful scientific contribution by sharing phenology data with regional and national organizations. Data-sharing will benefit the common goal of conservation and create avenues for collaboration with other scientists and conservation practitioners (Rosemartin 2013). In order to support Metro’s ongoing conservation efforts in Oregon white oak systems, I have implemented a three-part master’s project. Part one of the project examines Metro’s previously collected phenology data, providing descriptive statistics and assessing the strengths and weaknesses of the methods by which the data were collected. Part two makes recommendations for improving future phenology data-collection methods, and includes recommendations for datasharing with regional and national organizations. Part three is a collection of scientific vouchers documenting key plant species in varying phases of phenology for Metro’s teaching herbarium. The purpose of these vouchers is to provide a visual tool for Metro staff and volunteers who rely on plant identification to carry out aspects of their job in plant conservation. Each component of this project addresses specific aspects of Metro’s conservation program, from day-to-day management concerns to long-term scientific inquiry.

Assessment of Climate Change Vulnerability and Adaptation and Mitigation Strategies in the Southwest and California. USDA Southwest Climate Hub, October 2017. http://dx.doi.org/10.32747/2017.6965582.ch.

Full text
Abstract:
This report describes the potential vulnerability of specialty crops, field crops, forests, and animal agriculture to climate-driven environmental changes. Here, vulnerability is defined as a function of exposure to climate change effects, sensitivity to these effects, and adaptive capacity. The exposure of specific sectors of the agricultural and forestry industries varies across the region because the Southwest is climatically and topographically diverse. There is also variability in the sensitivity of different systems to the effects of climate change. Most significantly, there is potential within agricultural and forestry systems to adjust to climate-related effects either through inherent resilience or through conservative management practices. The purpose of this analysis is to describe regional vulnerabilities to climate change and adaptive actions that can be employed to maintain productivity of working lands in the coming decades.

Abstract:
In 2016 the government of Vanuatu introduced a National Gender Equality Policy. A second phase of the policy will be implemented in 2020–2024. Insights from key informants working on gender in Vanuatu reveal that there have been some positive developments in the first policy phase. A number of challenges remain, however, including limited capacity in a number of key institutions, and resistance to progress caused by prevailing conservative and patriarchal values and beliefs in Vanuatu. In the absence of other legal instruments for LGBTQI+/SOGI equality, perspectives vary on whether this aspect of gender equality should be included in the revised policy.
