Full textThe epizootic hemorrhagic disease (EHD) is an arthropod-borne virus that is on the OIE’s list (World Animal Health Organisation, formerly Office international des épizooties), this disease is mainly transmitted to wild (mainly deer) as well as domestic (primarily cattle) ruminants, by the bites of minute size midges, the culicoides (Diptera: Ceratopogonidae) also known as biting midges. In the beginning of the 21st century, EHD was emerged in Maghreb (North Africa) and in the Middle East (Turkey, Israel, Jordan), causing severe losses for the farmers and ranchers.The unexpected emergency of EHDV in Tunisia in 2006, simultaneously with the observation of EHDV-6 cases in Morocco and Algeria, has aroused great concern in the Tunisian agricultural sector, which had already to face the occurrence of other animal diseases orbivirus: African horse sickness in 1966 and bluetongue in 1999 giving examples of the possibility that deemed exotic disease could emerge and become endemic (case bluetongue).This project was carried out to raise the knowledge on the EHDV virus causing the infection in Tunisia in 2006, which led to the appearance of clinical signs similar to those of BTV.First, we prepared a sampling of various samples of cattle, Culicoides type imicola collected in 2006 and stored at the serum bank of IRVT. So, we searched therefore the genome of the EHDV by RT-PCR in order to characterize and isolate the virus. Results showed that EHDV-6 was actually the serotype circulating in Tunisia in 2006. This part of the job was published in Acta Veterinaria Hungarica.The second working paper concerned the potential presence of the EHDV-6 in Tunisia before and after the epidemic of 2006 in two animal species: cattle and camels. For this we looked for antibodies or viral genome from field samples collected from 2000 to 2014 cattle and camels. Following this study, we detected a possible circulation of EHDV-6 at a very low level of intensity among the cattle. The found results were discussed and made the subject of a publication to be in the newspaper Veterinaria iItaliana.Regarding the study on the dromedary species sensitive to BTV, we wanted to examine its potential role as a reservoir species for EHD virus. All serological and virological results of our study indicate that this species does not seem to play a role in the epidemiology of EHD.Finally, alongside these researches on EHD virus, we have investigated the presence of Bluetongue Virus in Tunisian samples from camels and cattle. The results were discussed.All these studies contribute to a better knowledge of EHDV-6 present in Tunisia and allows taking into account some species that are potentially reservoir. Some presented researches could be pursued to assess the role of the camel as a reservoir for Orbivirus and better identify species of the faunal inventory of Culicoides involved in transmission of orbivirus

Nous montrerons dans une introduction bibliographique comment l'utilisation de ces
hétéroéléments a permis l'isolation du premier diradical localisé singulet stable basé sur un
squelette formé uniquement des hétéroéléments bore et phosphore.
Dans un deuxième chapitre, nous nous intéresserons aux isomères de ce diradical, en
particulier ses isomères de valence. Après un bref retour sur le concept, nous étudierons les
facteurs qui permettent de stabiliser les différents isomères déjà connus. Nous montrerons
ensuite comment il a été possible d'isoler de nouveaux isomères.
Dans un troisième chapitre, nous nous arrêterons sur deux isomères de valence
particuliers et étudierons l'isomérie d'élongation (bond-stretch isomerism). Dans notre cas,
deux isomères qui ne diffèrent que par la longueur d'une liaison sont en équilibre. Grâce à
des études de RMN à température variable, nous mettrons en évidence l'influence des
facteurs électroniques dans cet équilibre.
Ce travail nous a amenés à nous interroger sur la possibilité de préparer un diradical
purement organique formé uniquement d'éléments de la seconde ligne : carbone et azote.
Cette réflexion nous a conduits à mettre au point une nouvelle méthode de synthèse de sels

Full textThe main purpose of this study is to investigate the syntactic constraints on anaphoric binding in korean which has a non reflexive pronouns and three reflexive pronouns. My description draws on the basic representational assumptions of lexical-functional grammar (lfg) and the theory of anaphoric binding of mary dalrymple (1993 : the syntax of anaphoric binding). By analyzing the facts, i first show that korean pronouns differ from each other both with respect to the domain in which they must be bound (or free) and with regard to the elements which can be their antecedents. Then i argue against the traditional approaches that the distribution patterns and antecedency conditions of korean pronouns can be determined by a unique and universal principle such as the binding principles of the generative theory. Basing on the ideas developed by mary dalrymple (1993) and anne zribi-hertz (1992 : de la deixis a l'anaphore : quelques jalons), i propose instead that binding requirements must be lexically associated with each pronoun. I take the theory of lexical-functional grammar as a framework for formalizing the syntactic constraints on anaphoric binding in korean. It should be noted, however, that my analysis is in large part theory-independent, and could be translated into any lexically-based theory

Full textThe evolution of the power semiconductors and the increase in the requirements on the performances of the systemslead to use variable speed also for power generation. Accordingly, the study concerns the association of a turbogenerator and a static frequency converter ; the frequency is adjusted by convenient commutations of the thyristors. The system imposes many constraints on the generator and on the converter, if the performances have to exceed thus of the current systems. Therefore, the system at variable frequency must take care of the exchanges of reactive power, to preserve a high efficiency and to limit the disturbances transmitted on the generator and on the network. The usual structures of converter are not well adapted for an association with a turbogenerator. A new approach considering the system converter-machine has been chosen. An original and effective converter is proposed which will be directly integrated into the machine. Its concept is based on the following rules : the generator and the converter work in cooperation and not like two independent entities ; the transfer of energy is used to get natural commutations of the thyristors ; the normal running of the generator is respected as well as possible. This approach of the system requires after preliminary studies, a demonstration of the principle of commutation and the definition of the rules, then a checking through numerical modelling. The principle was finally validated on a test bench under a weak voltage. By its simplicity and its efficiency, this new concept opens new prospects for variable speed application in the energy production

Full textDiradicals are known to be highly unstable molecules. For example, triplet 1,3-cyclobutanediyls can only be observed in matrices at very low temperature, whilst the corresponding singlet diradicals, formally resulting from the homolytic cleavage of the bridging s-bond, are predicted only as transition states for the inversion of the corresponding bicylo[1. 0. 0]butanes. The first part of this manuscript is devoted to the study of diradicals based on main group elements. The first chapter is a literature survey, which underlines the role of heteroelements in the isolation of the first stable localized singlet diradical. The framework of the latter is formed only of boron and phosphorus atoms. The second chapter focuses on the different isomers of this diradical, and especially its valence isomers. After an introduction to the theoretical concepts, the factors allowing the stabilization of the already known isomers are discussed, and the isolation of new isomers is described. .

Full textThis thesis aims at describing the psychic development of humanity, in the long term, by identifying several datable and documentable stages. A new method, which is founded on myths, has been devised to study the past of humanity and discover the psychic structure 50, 100, 200 millenniums ago. Nine different methods for dating have been devised; the most obvious uses migrations: a myth found in Central America and in Siberia dates from before the migration that populated the Americas, in 15,000 BP. These various methods enable a dating that spans 200,000 years. The myths often describe metaphorically the ritual practices and explain their meanings. Ritual practices are symbolic acting out of repressed instincts. The overall methodology recovers the myths of the last 200,000 years in their initial form through multiple comparisons between archaic myths, dates them, recovers the rites from the myths, identifies the psychic instincts at work and reconstructs the history of human psyche. There are only three basic ritual practices, sacrifice, hierogamy and possession. These three rites, or their symbolic equivalents, are organized in six complexes, each formed of closely related ritual variants, and myths explaining the meaning of the rites. These complexes progress throughout the course of time. Each was practiced by the whole humanity during tens of millenniums, then transformed progressively into the next one. The practice of the rites seems to have caused a long term rise of the death instinct intensity

Full textThe problems concerning the evolution of suprasegmental phenomens in slavonic languages have given rise to three major hypotheses which are refuted in the first part: that of a. Vaillant, who, using a comparative method, reconstitutes six common slavonic tones, of which three are secondary, of backward displacement on intonations dissociated from intensity, that of j. Kurylowicz, who bases most metatonies and accent movements on interferences between paradigms, that of p. Garde, who, extending the accentual properties of morphemes to whole flexional forms, presumes the existence of inaccentuable full words which take a circonflex accent later, the place depending ont he language. It is opportune to confront these incompatible theories with a realistic hypothesis of two fundamental laws: 1) the law of coalescence between intensity and tonality - regrouping the laws of hirt, and meillet - fortunatov, which is in itself a special case of a general law based on the properties of binary opposition succesivity simultaneity, and 2) a law of relative stability, discovered by internal and comparative analysis, and founded on three isomorphism: 1) isomorphism of long and short tones in serbo-croatian, which explains the metatonies by the intra-syllabic movements of the accent consecutive to the phonetical or morphological displacements of the word's limits; 2) isomorphism of the plans of content and expression, which confirms the analogical mechanisms of the extension of this law by remanence, a phenomenen of stabilisation in absentia of a change in praesentia; 3) isomorphism of syntagmatic and paradigmatic axes, which explains the circonflex tone by a law of maximum opposition analogue to the laws of dissimilation which ensure maximum contrasts

Full textThis thesis studies the microplasma ignited by a MHC, the plume created by a third electrode and the microjet when the gas is constrained to flows in the microhole. The self-pulsing regime of the MHC is a breakdown on the cathode external surface. The MHC corresponds to a capacitor in an electrical equivalent circuit. The argon atomic metastables density, measured by laser absorption spectroscopy resolved in time, shows that metastables are destroyed during the current pick and created in the postdischrage. The maximal density is superior to 1014cm-3 between 60 and 150Torr. To explain this evolution a simple numerical code is shown. The plume is a positive column. The breakdown voltage for this plasma is low compared to a plan-to-plan system (between 20 and 200V). The argon metastables density, measured by absorption spectroscopy, is maximal on the axis (1011cm-3) and decreases on the radius. A comparison with a 2D simulation is shown. When all the gas flows in the microhole, a supersonic microjet is created in the downstream room. The microjet does not modify the electrical behaviour of the microplasma and the plume. But the reactivity depends on the flow. In the air, the NO and NO2 concentrations, measured by IR laser absorption spectroscopy in the downstream room are independent on the pressure and flow. The NO molecules are created in the microhole. The NO2 molecules are created in the downstream room by reaction between O3 and NO

Full textJoining is a powerful assembling technique which makes more and more possible to replace or supplement the other traditional assembling methods (welding, riveting or bolting). This assembling technique consists in the adhesion by molecular attraction between two parts and an interposed adhesive which must ensure the transmission of efforts. This assembling method distributes the stresses over the whole joining surface and removes the concentrations of stresses on the boundary of holes generated by bolting or riveting assemblies. A major element in dimensioning the adhesive assemblies is represented by the analysis of the stress field in the adhesive layer. In the present study we show several methods of analysis: an analytical and numerical analysis of the cylindrical adhesive bonded joints and an analytical, numerical and experimental analysis of the double-lap adhesive bonded joints. The analytical and numerical models enable us to determine the stress distributions and intensities in the adhesive layer and also to make an analysis of geometrical and physical parameters influence on the stress field: adhesive thickness, the length of adhesive cover, the Young's modulus of the adhesive and the relative rigidity of the joined parts
