Texte intégralOur aim is to show that the principle of the axiological neutrality of judges and therefore of their judgment, of revolutionary origin, has had the effect of reducing the law to the rank of a pure and simple instrument of political power; a power whose existence – and therefore that of its law (its "positivity") – fundamentally depends on the effective possession of force. That situation is the consequence of an ideological choice which positivism, de facto the dominant theory in law faculties, has endorsed with a pseudo “scientific” validity. As a result, the vast majority of jurists have long since ceased to wonder about "the Legal being". According to jurists, such a question can only be of interest to theoreticians or philosophers whose speculations have in fact nothing to do with the only true law: that produced by the competent political authorities (according to their law), the application of which can be effectively ensured. And for judges, "to interpret the law" can have no other meaning than to apply as faithfully as possible that law which, in passing from its place of political production into their hands, has purportedly been shed of all moral or ethical content. A law which, for those who implement it, is therefore an object void of any mystery, in accordance with what they have been taught, of "immediate evidence". How indeed can we doubt what the law is, whether one is a specialist in law or even a simple litigant, when State standards are omnipresent and followed by indisputable effects on our minds and bodies? That evidence is in fact misleading and prejudicial in that it hinders any critical reflection. For what professional jurists as a whole believe they know, and what judges "hold" in "interpreting the law" is nothing other, under that name, than a political will in its normative form. For it to be otherwise, for the Law to exist as an autonomous object and discipline, judges, who are the only other possible source of normative legitimacy in the citystate, must open up the law and its function to another dimension than its purely political basis, which is necessary but insufficient. And it is in search of this openness to which legal thought leads with Camus, the philosopher of the meaning of human existence with which the law, created by the people for the people in order to regulate their social behavior, sanely can do no more than integrate. With the author of The Rebel, that openness must be seen as a certain form of confrontation with political power, and as a constant concern for balance; necessarily under strain, but which does not exclude the pursuit of a certain harmony, of a vision of the Law as an art of living together. An issue which Camus, philosopher and artist, in the last chapter of his essay, addresses with "Mediterranean Thought"

Texte intégralENGLISH ABSTRACT: The use of toxicity tests to evaluate the quality of streams affected by mixtures such as acid mine drainage (AMD), adds value to assessments whereby site-specific toxicological data may identify toxicants that pose a threat to humans. To successfully evaluate the risk of combined mixtures, an improved understanding of the individual components, their uptake, metabolism, excretion and mode of action is required. This study aimed to identify the extent of AMD toxicity in a dose dependant manner on the MCF-7 cell line. The first study site associated with gold mining was chosen as the Tweelopies Stream situated in the Gauteng province of South Africa. The AMD effluent (un-neutralised) contaminating the Tweelopies Stream had undergone pH-neutralisation using a reactor-bed limestone technology incorporating the use of both calcium carbonate (CaCO3) powder and limestone beds. The second study site, the Kromdraai River, is situated in the eMalahleni region of South Africa where a predominance of coal mining exists. The pH -neutralisation of the AMD (un-neutralised) contaminated Kromdraai River was performed using a caustic soda (NaOH) precipitation technique. This study demonstrated the rapid and effective application of the comet assay as a screening tool for AMD-associated DNA breakages in the human cell line, MCF-7. Moreover, the study analysed parameters of cellular survival, DNA fragmentation and variations in morphologies indicative of cellular death. Collectively, the cyto-genetic aberrations observed in the MCF-7 cells as a result of exposure to gold and coal mining associated AMD, confirms the urgency of incorporating high-throughput screening in ecological toxicity assessment to evaluate cellular damage at genetic levels in low dose exposures where detection might be missed.
AFRIKAANSE OPSOMMING: Die gebruik van toksisiteitstoetse om die gehalte van strome te evalueer wat geraak word deur mengsels soos suur mynwater (SM), gee waarde aan spesifieke toksikologiese data van gifstowwe wat 'n bedreiging vir die mens kan identifiseer. Om die risiko van gekombineerde mengsels en hul individuele komponente beter te begrip en suksesvol evalueer, is hul opname, metabolisme, uitskeiding en modus van aksie nodig. Hierdie studie het gepoog om die omvang van SM-toksisiteit in 'n dosis afhanklike wyse op die MCF-7-sellyn te identifiseer. Die eerste studie-area wat gekies is, hou verband met goudmyn-ontginning, en is die Tweelopiesspruit, geleë in die Gauteng-provinsie van Suid-Afrika. Die SM-uitvloeisel (on-geneutraliseerde) wat die Tweelopiesspruit besoedel, het pH-neutralisasie ondergaan met behulp van die integrasie van 'n reaktor-bed kalksorpsietegnologie wat gebruik maak van beide kalsiumkarbonaat (CaCO3) poeier en kalksteenbeddens. Die tweede studie-area, is die Kromdraairivier geleë in die eMalahleni-streek van Suid-Afrika, waar steenkoolontginning die oorheersende aktiwiteit is. Die pH-neutralisasie van die SM (on-geneutraliseerde) in die geval van die Kromdraairivier word met behulp van 'n bytsoda (NaOH) neerslag tegniek, uitgevoer. Hierdie studie het die komeet-toets getoon as 'n vinnige en doeltreffende toepassing vir SM-geassosieerde DNA-breekskade in die menslike sel lyn, MCF-7. Verder het die studie parameters van sellulêre oorlewing, DNA-fragmentasie en variasies in sel morfologieë wat ‘n aanduiding van sellulêre dood is, ontleed. Gesamentlik dui die resultate daarop dat die sitogenetiese afwykings wat in die MCF-7-selle waargeneem is, as 'n gevolg van blootstelling aan goud- en steenkool-geassosieerde SM is. Die studie het verder die dringendheid van die integrasie van hoë-deurset tegnologieë in ekologiese toksisiteitstoetse in selle wat genetiese skade mag ondergaan, na 'n lae dosis blootstelling waar opsporing dalk gemis word, ondersteun.

Texte intégralThe annihilation of weakly interacting massive particles (WIMPs), accumulated in gravitational potentials (e.g., the core of the Earth, the Sun or the Galactic halo) would lead to neutrino production. This thesis investigates the possibility of searching for WIMPs in the form of the lightest supersymmetric particle (neutralino) trapped in the Sun using the AMANDA-II neutrino telescope. AMANDA-II is a large Cherenkov detector located deep in the ice at the geographical South Pole. The presented work is based on data taken during the year 2001. An analysis optimized to search for the neutralino-induced flux from the Sun has been developed. The observation of no excess with respect to the expected atmospheric neutrino background has been interpreted as an upper limit on the neutralino annihilation rate in the Sun and on the neutralino-induced muon flux in the vicinity of the detector.

Texte intégralAcid mine drainage (AMD) is the most serious environmental problem facing the mining industry. AMD is formed when sulfide minerals in waste rock or tailings are oxidized in the presence of water and oxygen to form highly acidic, sulfate and metals-rich drainage. Some methods exist to reduce the formation of AMD in a waste rock pile: layered co-mingling, cover, liner and co-disposal of waste rock with fine materials to limit oxygen fluxes. These methods are based on the use of mine tailings. The aims are to limit the transfer of oxygen and water in a waste rock pile during its construction and reduce thermal gas convection. However, mine tailings can themselves generate AMD and need to be neutralized by the addition of alkaline material. The purpose of this study is to evaluate the capacity of alkaline industrial wastes to neutralize tailings. Alkaline industrial wastes which were selected are cement kiln dust (CKD) and red mud bauxite (RMB). These alkaline materials are used to keep neutral conditions even if water saturation is disrupted. A series of batch leaching tests and column leaching tests were conducted in order to investigate the long-term neutralization potential of alkaline materials and the quality of the drainage water. The batch leaching tests have indicated the minimum percentage (10%) of alkaline material required to keep neutral pH conditions, and to discern whether mineral solubility controls exist for particular elements. Column leaching tests have shown the hydrogeochemical behaviour of different dispositions of materials. When the fine-grained layer overlays reactive waste rock, a delay was observed before obtaining near neutral pH. In the cases where the fine-grained layer is below or mixed with the waste rock, the near neutral pH values are directly reached. The co-disposition offers short-term neutralisation only. Finally, a sequential extraction method was used to determine the degree of fixation of metals.

Texte intégralDuring the LHC 8 TeV Run1, many searches were dedicated to the supersymmetric models. Among those, the search for the chargino-neutralino (C1, N2) pair production in final states with 1 lepton, 2 b-jets consistent with a Higgs boson and missing transverse energy. This search had negative outcome resulting in excluding C1, N2 masses up to 250 GeV for a massless lightest neutralino (N1) at 95% C.L.. The Run1 search used the 8 TeV ATLAS data collected in 2012. In this thesis, this search with ATLAS at LHC 13 TeV Run2 is presented, it uses 36.1 fb$^{-1}$ ATLAS data collected in 2015 and 2016. This Run 2 search provides an unprecedented sensitivity to high mass C1, N2 production. However, no evidence of new physics is observed and tighter new limits are placed on the C1, N2 production, with significant improvements over previous searches: C1, N2 masses up to 680 GeV for a massless N1 are excluded at 95% C.L. The identification of b-jets plays a significant role in this analysis. In this thesis, we present studies of the robustness of b-tagging performance with various conditions of the pixel detector, being the most important sub-detector for b-tagging. As most SUSY searches at the LHC, this analysis is carried out using Simplified Model of SUSY, i.e. the mass spectrum is chosen by hand and the considered SUSY decays are forced. Suspect3 is one of the theory tools utilized to map the search result into realistic SUSY models. This thesis presents the post Higgs discovery SuSpect3 version we have been working on. This version takes advantage of the very important new Higgs boson mass input to constrain other basic model parameter currently given as an input

Texte intégralThe Standard Model of particle physics has been strengthened by the recent discovery of the long-awaited Higgs boson. The standard cosmological model has met the challenge of the high precision observations in comology and astroparticle physics. However these two standard models face both several theoretical issues, such as the naturalness problem in the Higgs sector of the Standard Model, as well as observational issues, in particular the fact that an unknown kind of matter called Dark Matter accounts for the majority of the matter content in our Universe. Attempts to solve such problems have led to the development of New Physics models during the last decades. Supersymmetry is one such model which addresses the fine-tuning problem in the Higgs sector and provides viable Dark Matter candidates. Current high energy and high precision experiments give many new opportunities to probe the supersymmetric models. It is in this context that this thesis is written. Considering the Minimal Supersymmetric Standard Model (MSSM), the simplest supersymmetric extension of the Standard Model of particle physics, and its conventional Dark Matter candidate, the neutralino, it is shown that collider constraints could provide informations on the very early Universe at the inflation area. It is also demonstrated that the Indirect Detection of Dark Matter, despite several drawbacks, can be a powerful technique to probe supersymmetric Dark Matter models. Beyond the MSSM it is shown that unique characteristics of the Dark Matter candidate in the NMSSM could be probed at colliders. The study of a supersymmetric model with an extended gauge symmetry, the UMSSM, is also developed. The features of another Dark Matter candidate of this model, the Right-Handed sneutrino, are analysed. More general constraints such as those coming from low energy observables are finally considered in this model

Debove, Jonathan. « QCD resummations for gaugino-pair hadroproduction ». Grenoble, 2010. http://www.theses.fr/2010GRENY030.
Texte intégralWeak-scale Supersymmetry (SUSY) is a very well motivated extension of the Standard Model of particle physics. Linking bosons and fermions in an elegant formalism, SUSY allows for a natural solution of the hierarchy problem and for accurate unification of the three Standard Model gauge couplings at a high unification scale. Furthermore, if R-parityis conserved, it provides a convincing candidate for the large amount of cold dark matter observed in the Universe. In the Minimal Supersymmetric Standard Model, this is generally the lightest neutralino, one of the spin-1/2 supersymmetric partners of the electroweak gauge bosons (gauginos) and of the Higgs bosons (Higgsinos), which mix to form four neutral (neutralino) and two charged (chargino) mass eigenstates. After an introduction to supersymmetry, we present the transverse-momentum and threshold resummation formalisms. We then consider the gaugino-pair production at current hadron colliders, i. E. At RHIC, Tevatron and LHC. We study the corresponding effects of polarised initial hadrons and full SUSY-QCD corrections. We finally apply transverse-momentum and threshold re-summations to gaugino-pair production, and show that they have important impact on the transverse-momentum and invariant-mass distributions. Throughout these studies, we also investigate the theoretical uncertainties coming from scale and parton-density function variations

Texte intégralThe nature of the dark matter in the Universe is one of the greatest mysteries in modern astronomy. The neutralino is a nonbaryonic dark matter candidate in minimal supersymmetric extensions to the standard model of particle physics. If the dark matter halo of our galaxy is made up of neutralinos some would become gravitationally trapped inside massive bodies like the Earth. Their pair-wise annihilation produces neutrinos that can be detected by neutrino experiments looking in the direction of the centre of the Earth.
The AMANDA neutrino telescope, currently the largest in the world, consists of an array of light detectors buried deep in the Antarctic glacier at the geographical South Pole. The extremely transparent ice acts as a Cherenkov medium for muons passing the array and using the timing information of detected photons it is possible to reconstruct the muon direction.
A search has been performed for nearly vertically upgoing neutrino induced muons with AMANDA-B10 data taken over the three year period 1997-99. No excess above the atmospheric neutrino background expectation was found. Upper limits at the 90 % confidence level has been set on the annihilation rate of neutralinos at the centre of the Earth and on the muon flux induced by neutrinos created by the annihilation products.

Texte intégralLes mammifères alpins sont vulnérables aux changements climatiques car ils sont confinés à une certaine altitude. Toutefois, des adaptations physiologiques et comportementales chez certaines espèces d’animaux fouisseurs pourraient, en partie, atténuer les impacts négatifs des changements climatiques. En effet, chez les animaux fouisseurs qui hibernent, le fait d’avoir recours à la torpeur en hiver en plus d’avoir accès à des terriers souterrains permet aux individus de réduire leur exposition aux conditions extérieures lorsqu’elles sont défavorables. J’ai étudié les liens entre les facteurs environnementaux et les variations interannuelles de la masse corporelle et de la survie chez les adultes d’une population de marmottes des Rocheuses. Mon étude utilise des données qui ont été récoltées pendant 14 ans à Caw Ridge en Alberta. J’ai émis l’hypothèse que la variation interannuelle dans les conditions environnementales au printemps, à l’été et en hiver déterminerait la masse corporelle des individus pendant l’été en plus de la survie annuelle via des effets directs sur la qualité et la disponibilité des ressources alimentaires. J’ai aussi prédit que la masse à la fin de la saison d’activité serait l’un des principaux déterminant de la survie annuelle. Mes résultats démontrent un effet positif des printemps hâtifs sur le gain de masse estival et la survie annuelle. J’observe aussi que la masse à l’émergence des marmottes qui ont connu des hivers froids et rigoureux est 47% inférieure à celle des marmottes qui ont connu des hivers plus doux. Toutefois, les marmottes qui émergent avec une masse plus faible aux printemps suivants des hivers plus rigoureux ont un gain de masse plus important pendant l’été. Ainsi, à la fin de l’été, elles atteignent une masse similaire à celles qui ont une masse plus élevée à l’émergence suivant un hiver plus doux. Cela suggère que les individus adoptent une stratégie d’allocation des ressources qui leur permet de maximiser leur gain de masse estival afin de survivre pendant la prochaine période d’hibernation. Cette capacité des marmottes à maximiser leur gain de masse estival contribue probablement à expliquer le fait que je n’ai pas observé d’effets de la masse à la fin de la saison active sur la survie annuelle. Bien que les adultes devraient avoir des réponses tamponnées aux changements environnementaux comparés aux juvéniles, notre étude suggère que la masse corporelle et la survie des adultes peuvent être considérablement affectées par les conditions environnementales et que les changements prévus dans les conditions climatiques pourraient avoir des effets sur les espèces d’animaux fouisseurs qui hibernent en milieux alpins

The alignment between all layers of the tracker, the sub-detector of CMS allowing the reconstruction and the measurement of the momentum of charged particles, is made by using tracks of particles created during collisions and tracks created by the passage of cosmic muons through this sub-detector. A first part of the presentation will be dedicated to the reconstruction of the tracks of these cosmic muons during collisions. A new method, called regional cosmic reconstruction, was developed and implemented. The 69 % efficiency and the fake rate around 1 % allow to use these tracks for the alignment. The second part, dedicated to the analysis of collision data, will concern the search of particles predicted by a model of extension of the Standard Model, the Supersymmetry, in a particular scenario, the light Stop scenario. In the case of a strong mixing in the third generation of squarks, the stop, supersymmetric partner of the top quark, could be light. In the analysis developped during this thesis, we were interested in the case where the mstop < mtop. In the MSSM with R-parity conservation, the gluino would be created by pair and would decay in a stop squark and a top quark. Stop would decays in a c quark and a neutralino, the lightest supereymmetric particle of the model, stable and interacting weakly. No excess with regards to Standard Model predictions was observed in 40pb-1 of data recorded by CMS in 2010. The limits obtained at 95 % confidence level allow to exclude masses of stop until 175 GeV for masses of gluinos going up to 350 GeV and low differences of masses between stop and neutralino

Texte intégralL'étude de la production de paires de squarks bottom se désintégrant dans le canal $\tilde b \rightarrow b+ \tilde \chi^0_1$ a été réalisé à partir des premières données du Run II utilisables pour la physique. L'échantillon utilisé correspond à une luminosité intégrée de 4.1 +- 0.4 pb-1. Cette étude se place dans le cadre de modèles supersymétriques avec conservation de la R-parité, et dans le cas où le $\tilde b$ est suffisamment léger pour limiter ses désintégrations au canal $\tilde b \rightarrow b+ \tilde \chi^0_1$ (BF ~ 100%). L'impossibilité d'utiliser l'étiquetage des jets b a conduit à considérer l'état final "jets et énergie transverse manquante (E_T barré)".
Cette étude préliminaire a abouti à deux résultats importants. Tout d'abord, à l'issue des coupures d'analyse la distribution de E_T barré ne présente pas de queues anormales. Ceci montre que les effets instrumentaux qui perturbent la mesure de E_T barré sont bien compris. C'est une étape importante puisqu'un grand nombre de canaux de physique du Modèle Standard et de ses extensions, i.e. la supersymétrie, présentent une quantité significative de E_T barré.
Aucun excès d'événements par rapport aux prédictions du Modèle Standard n'a été observé. Des limites à 95% C.L. sur la section efficace de production d'événements au delà du MS dans l'état final "jets et E_T barré" ont été posées.
