Atualmente existe duas principais abordagens para resolver este problema: pela introdu??o nas equa??es de Einstein de um termo o qual representa um novo tipo de fluido (a chamada energia escura) possuindo caracter?sticas ex?ticas ou pela modifica??o da teoria de gravita??o. Nesta tese n?s focamos na segunda abordagem, particularmente, as teorias conhecidas como teorias f(R) de gravidade as quais t?m recebido muita aten??o nos ?ltimos anos. Neste contexto, a equa??o de Raychaudhuri permite examinar a estrutura do espa?o-tempo como um todo sem solu??es espec?ficas das equa??es de Einstein, desempenhando assim um papel central para a compreens?o da atra??o gravitacional em Astrof?sica e Cosmologia. Na teoria da Relatividade Geral sem uma constante cosmol?gica, uma contribui??o n?o-positiva da geometria do espa?o-tempo a equa??o de Raychaudhuri ? usualmente interpretada como a manifesta??o do car?ter atrativo da gravidade. Neste caso, condi??es de energia espec?ficas - de fato a condi??o de energia forte - deve ser assumida, a fim de garantir o car?cter atrativo. No contexto das teorias f(R) de gravidade, no entanto, mesmo assumindo as condi??es de energia usuais pode-se ter uma contribui??o positiva para a equa??o de Raychaudhuri. Al?m de nos fornecer uma maneira simples de explicar a observada expans?o acelerada do Universo, este fato abre a possibilidade de um car?ter repulsivo deste tipo de gravidade. Nesta tese n?s abordamos o car?cter atrativo/n?o-atrativo da gravidade f(R) ? luz da equa??o de Raychaudhuri e fazemos uso da condi??o de energia forte, juntamente com estimativas recentes dos par?metros cosmogr?ficos, para colocar limites em uma classe paradigm?tica de teorias f(R) de gravidade. / The observational evidence of the accelerated expansion of the Universe has been the main reason for a revision of the cosmological evolution as predicted by General Relativity (GR). Currently there are two main approaches to solving this problem: by introducing in the Einstein?s equations a term which represent a new kind of fluid (the so-called dark energy possessing exotic features) or by the modification of the gravitation theory. In this thesis we focus on the second approach, particularly the theories know as f(R) theories of gravity, which have received many attention in the last years. In this framework, the Raychaudhuri equation makes possible to examine the whole of spacetime structures without specific solutions of Einstein?s equations, playing so a central role to the understanding of gravitational attraction in Astrophysics and Cosmology. In the general relativity theory of gravity without a cosmological constant, a non-positive contribution from the spacetime to Raychaudhuri?s equation is usually interpreted as manifestation of the attractive character of gravity. In this case, particular energy conditions - indeed the strong energy condition - must be assumed in order to guarantee this attractive character. In the context of f(R) theories of gravity however, even assuming the usual energy conditions we may have a positive contribution to Raychaudhuri?s equation. Besides giving us a simple way to explain the observed accelerated expansion of the Universe, this fact opens the possibility of a repulsive character of this kind of gravity. In this thesis we address the attractive/non-attractive character of f(R) theories of gravity at the light of Raychaudhuri?s equation and make use of the strong energy condition, jointly with recent estimated values for the cosmographic parameters, in order to put bounds on a paradigmatic class of f(R) theories of gravity.

In this research, we trace the sociolinguistic profile of the speakers from the state of Alagoas concerning the variation of the verbs "ter" and "haver" in existential constructions, in order to analyse how that variation occurs and verify if the alternance of those verbs, in the alagoana speech, reflects either a process of stable variation or a change in progress. For the development of this work, we appeal to the Theory of Linguistics Variation (LABOV, 2008[1972]) which deals the variation and linguistics change and includes the variable use of the language in its social context. In this way, after the delimitation of the dependent variable and of the independent variables selected as potentially relevant in the variation under analysis, namely, animacity of the internal argument, nature of the internal argument, verbal tense, gender, age and scholarity, we stratify our sample and we did the gathering and transcription of data, as well as, the analysis and codification of all existential constructions formed with the verbs present in the corpus. For the quantitative analysis, we use the software VARBRUL, which delimited the variables statically nonsignificant and the variables statically significant in variation under study, showing not only that there is variation “ter” and “haver” existentials in the community studied and that the uses of “ter” existential is greater than the uses of “haver” existential, as well as that such variation is conditionated by the factor groups scholarity, verbal tense, age and nature of internal argument, leading us to argue that, in the alagoana speech, such variation reflects a process of change in cours in the direction of “ter” existential. / Coordenação de Aperfeiçoamento de Pessoal de Nível Superior / Nesta pesquisa, traçamos o perfil sociolinguístico dos falantes alagoanos em relação à variação dos verbos ter e haver em construções existenciais, com o intuito de analisar como essa variação ocorre e de verificar se a alternância desses verbos, na fala alagoana, reflete um processo de variação estável ou de mudança em progresso. Para o desenvolvimento deste estudo, recorremos à Teoria da Variação Linguística (LABOV, 2008[1972]) que trata da variação e da mudança linguística e contempla os usos variáveis da linguagem em seu contexto social. Dessa forma, após a delimitação da variável dependente e das variáveis independentes selecionadas como potencialmente relevantes na variação em estudo, a saber, animacidade do argumento interno, natureza do argumento interno, tempo verbal, sexo, faixa etária e escolaridade, estratificamos nossa amostra e fizemos não só a coleta e a transcrição dos dados, mas também a análise e a codificação de todas as construções existenciais formadas com os verbos ter e haver presentes no corpus. Para a análise quantitativa dos dados, utilizamos o programa computacional VARBRUL, que delimitou as variáveis estatisticamente não significativas e as variáveis estatisticamente significativas na variação em estudo, mostrando não só que há variação ter e haver existenciais na comunidade estudada e que o uso de ter existencial é bem maior do que o uso de haver existencial, como também que tal variação é condicionada pelos grupos de fatores escolaridade, tempo verbal, faixa etária e natureza do argumento interno, levando-nos a argumentar que, na fala alagoana, tal variação reflete um processo de mudança em curso na direção de ter existencial.

The aim of the thesis is to study the possibilities of the electronic frequency ?lter com- posed of active elements operating in current mode. The main opportunities lie in the change control parameters, most are marginal or quality factor frequency. As the active elements are considered especially CC (Current Convejor), controllable current ampli?er DACA (Digitally Adjustable Current Ampli?er) or combination with the current tracker MO-CF (Multiple Output Current Follower). Another part will focus on the management of the above parameters using digital potentiometers and choosing the appropriate ?lter structure. The ?nal task was to digital control parameters using a PC and measuring its properties.

Entre 1999 i 2003 es va desenvolupar un projecte Life de restauració a la maresma de La Pletera, afectada per un pla urbanització, i a la llacuna del Ter Vell, amb un elevat grau d'eutròfia (aiguamolls del Baix Ter, NE Península Ibèrica). L'objectiu d'aquesta tesi és establir el funcionament d'ambdós ecosistemes, analitzar-ne la problemàtica ambiental i avaluar els efectes de la restauració. A la maresma de la Pletera, es va analitzar el paper de la hidrologia en la composició i dinàmica dels nutrients i del zooplàncton en cinc llacunes, tres de les quals havien estat creades dins el projecte de restauració com a nous refugis per una espècie de peix amenaçada (Aphanius iberus). La hidrologia es va caracteritzar per un llarg període de confinament sense entrades d'aigua, interromput de manera irregular per inundacions puntuals. La dinàmica del nitrogen inorgànic es va relacionar amb les entrades d'aigua, mentre que la del fòsfor, del nitrogen total i de la matèria orgànica es va relacionar amb els processos d'acumulació i reciclatge intern durant el confinament. El zooplàncton es va analitzar mitjançant la combinació d'aproximacions taxonòmiques i de mides. L'estructura de mides de la comunitat es va veure més afectada per les interaccions tròfiques (depredació i competència) mentre que l'estructura taxonòmica va ser més sensible a factors abiòtics (nutrients). El ràpid creixement de la població A. iberus en les noves llacunes va suggerir que aquestes havien proporcionat l'hàbitat adequat per a l'espècie, almenys a curt termini. Les actuacions de restauració a la llacuna del Ter Vell es van centrar en la millora de la qualitat de l'aigua mitjançant (1) la construcció d'uns aiguamolls per depurar l'aigua d'entrada i (2) el dragat del sediment en diversos punts. Simultàniament a la restauració, però de forma independent, la gestió agrícola de l'aigua va reduir dràsticament el cabal d'entrada d'aigua dolça a la llacuna, provocant un canvi en el règim hídric. Es van analitzar els efectes a curt termini d'aquest canvi sobre la limnologia i el zooplàncton de la llacuna. Abans del canvi, la hidrologia era artificial ja que s'havia prolongat l'entrada d'aigua dolça d'acord amb la demanda agrícola, i per tant la llacuna presentava una elevada taxa de renovació de l'aigua i majors concentracions de nutrients. Després del canvi, la hidrologia va dependre més del clima, es van reduir les entrades d'aigua i es va allargar el període de confinament. La composició y dinàmica dels nutrients va tendir a assemblar-se a l'observada a les llacunes de la maresma, mentre que la comunitat del zooplàncton no ho va fer. L'estat ecològic de la llacuna va millorar després del canvi en el règim hídric. / Between 1999 and 2003, a restoration Life project was developed in La Pletera salt marshes, affected by an urbanisation plan, and in the Ter Vell lagoon, a highly eutrophic lagoon (Baix Ter Wetlands, NE Iberian Peninsula). The aim of this thesis is to establish the natural functioning of both ecosystems, analyze their environmental problematic and also to evaluate the effects of the restoration measures.In La Pletera salt marshes, the role of the hydrological regime in the nutrient and zooplankton composition and dynamics was analysed in five brackish lagoons. Three of them were created in the framework of the restoration project as new refuges for an endangered fish species (A. iberus). The hydrology was determined by a prolonged period of confinement without water inputs, irregularly interrupted by sudden flooding events. While the dynamics of inorganic nitrogen depended on the water inputs variability, dynamics of phosphorus, total nitrogen and organic matter was related more to the cumulative mechanisms and internal recycling during the confinement periods. The zooplankton community structure was analysed by means of the combination of taxon- and size-based approaches. Whereas the community size structure was more affected by trophic interactions (predation and competition), the taxonomic structure appeared to be more sensitive to abiotic factors (nutrients). The fast growth of the size population of A. iberus in the new lagoons suggested that they had provided a suitable refuge for this species, at least in the short-term.Restoration actions in the Ter Vell lagoon were focused on the improvement of the water quality by means of (1) wetlands construction to reduce nutrient inputs and (2) sediment dredging. Simultaneously, but independent of the restoration activities, water management in agriculture drastically reduced the freshwater inflow to the lagoon and, therefore, changed the hydrological regime. The short-term effects of this hydrological change on the limnological characteristics and the zooplankton of the lagoon were analysed. Before the change, the hydrology was artificial since the freshwater flooding period was prolonged due to the high agricultural demand. As a result, the lagoon showed a high water turnover rate and high nutrient concentrations. After the change, hydrology was climate-dependent, with scarce water inputs and prolonged confinement periods. Then, the nutrient composition and dynamics tended to be more similar to those observed in the salt marsh lagoons. However, zooplankton did not tend to resemble to that of the salt marsh lagoons. The ecological status of the Ter Vell lagoon was improved after the hydrological change.

Cette thèse, qui s’inscrit dans le questionnement économique général sur la recherche d’outils de régulation des industries de réseaux, questionne la pertinence du choix français de régionalisation ferroviaire. Ce dernier, depuis la réforme introduite par la loi SRU, associe le maintien du monopole d'exploitation de la SNCF pour le Transport Express Régional (TER) avec la décentralisation aux Régions d'une prérogative jusqu'alors assurée de manière bureaucratique et centralisée. Dans cet environnement institutionnel, original au regard du mouvement européen, les Régions françaises ont-elles réussi à écrire et à gouverner le "système SNCF-TER" ?Pour répondre à cette double interrogation, l’auteur mobilise la théorie néo-institutionnelle, à partir de laquelle il propose une matrice interprétative de l’architecture économique des conventions TER et présente une transposition de la méthode des comptes de surplus (MCS), pour l’étude de la performance économique de ces contrats.Les résultats obtenus, sur l’échantillon des sept régions qui ont expérimenté la régionalisation, ne confirment que partiellement les déductions habituelles obtenues à partir de la théorie standard du monopole et de la capture du réglementateur par la firme régulée. Si la contractualisation SNCF / Régions, très éloignée du modèle « net cost » (présent dans de nombreux pays en Europe), exprime l’acceptation par le Législateur d’une large couverture des risques industriels, commerciaux, et plus encore sur investissements, par la Collectivité, la régionalisation s’est traduite par une grande diversité contractuelle. Une analyse fine montre le caractère hybride des modes de gouvernance que l’auteur qualifie de « fiduciaro-autoritaires ». La MCS révèle que si l’effet du monopole est bien présent et s’impose aux Régions, il ne profite guère à la SNCF, mais plutôt à RFF. Tendanciellement, les voyageurs sont devenus « gagnants » de la régionalisation ferroviaire. / This thesis, which fits the general economical issues on the research tools of the network industries regulation, questions the relevancy of the French railways regionalisation. The latter, since the reform introduced by the law SRU associates the maintenance of the railway service operating monopoly for the Regional Express Transport (TER) with the decentralisation to the regions, so that they benefit from a prerogative ensured hitherto in a centralised and bureaucratic way. In this institutional environment, original compared to the European movement, have the French regions managed to write and to govern the "SNCF-TER system” ?To answer both questions, the author used the neo-institutional theory from which he offers an interpretative array on the economical structure of the TER conventions and presents a transposition of this method on surplus accounts to study the economical performance of these contracts.From a panel of seven regions which have tested the regionalisation, the results can only partially confirm the usual deductions made from the standard theory of the monopoly and the capture of the regulator by the regulated firm. If the contracting SNCF/Regions, far from the “net cost” model, expresses that the legislature accepts a broad industrial and commercial insurance cover, and more on investments made by the community, then regionalisation resulted in a larger variety of employment contracts.A detailed analysis shows the hybrid character of the governance methods which the author calls “fiduciaro-authoritarian”. The method on surplus accounts reveals that, while the effect of monopoly is present and essential to the regions, then it means little benefit to the railway operator but much to RFF. Today travellers have trendily become the “winners’ of the rail regionalisation.

The topic of the diploma thesis BUT Area Kravi hora is a strategic study of the BUT area at Kravi hora from the previous semester to a scale of 1:200. The subject is the elaboration of the concept in order to bring together the interests of BUT and Brno city in this extraordinary territory for the benefit of both subjects. This work deals in detail with newly proposed objects in the BUT territory. A number of regulations have been issued in the territory limiting the subsequent use of the area, but the current area does not suit the existing potential of the site. The main concept was a creation of a set of buildings that will serve the University for representation and public activities, while allowing the access and use of the general public by the inhabitants of the city of Brno. The whole site will be set up in a newly-built city-wide park and other park areas that will create an attractive part of the now-inaccessible and unspoilt area connecting Veveri with Kravi hora. There will also be added additional features inspired by the existing features in the area, namely the Art Colony with ateliers, then Business Units and spacious Public Workshops. The entire Kravi hora area will be interwoven with a number of services serving both adults and children. The new proposal will also lead to the diversion of car traffic from the whole territory in order to ensure the safest relaxed movement of visitors. There will be numerous parking spaces located on the outskirts of the area. The main goal is to create a strong concept focusing on relaxation, health, education and sport, which should result in the overall opening and attractiveness of the territory.

An increase in international trade has resulted in an increase in the carriage of goods by sea, which has also promoted the business of marine insurance on a very huge scale. Marine insurance contracts fall within both the admiralty jurisdiction where admiralty laws apply and special contract law where the rules and principles of contract law apply. In certain circumstance this has left the courts with a dilemma in deciding in particular cases which law should apply; whether maritime law, contract law or marine insurance law. There are certain principles under the law of contract that are said to be profound and cannot be ousted easily by substantive law. The principle of party autonomy is one of these principles and it has gained international recognition through a number of cases. However, to date, courts are faced with difficulties in deciding whether to uphold the choice of law on jurisdiction and governing law exercised by parties or resort to substantive law, either by virtue of admiralty law or any other statutes in a country, which provisions may be contrary to the clause on choice of law under the contract. In South Africa practice has shown that courts are always reluctant to apply the clause on choice of law if they believe such application is against the public policy and interest in South Africa. This begs the question as to the precise meaning and effect of “public policy and interest” and how this principle influences the long-standing and well-established principle of party autonomy in admiralty jurisdiction. This dissertation is aimed at providing a legal response to this problem by analysing case law and the different viewpoints of various writers. It is imperative to investigate if their decisions and views answer all the uncertainties with regard to the meaning and the effect of the concept of “public policy and interest” on the principle of party autonomy. / LLM (Import and Export Law), North-West University, Potchefstroom Campus, 2014
