Território, cidade e rede: o papel de Rondonópolis na expansão da soja no Cerrado Mato-Grossense / Territory, city and net expansion: the role of Rondonopolis in soil development in Mato Grosso\'s Cerrado

Silva, Elias da 14 January 2010 (has links)
A presente pesquisa tem como objetivo analisar o papel da cidade de Rondonópolis no processo em rede de expansão territorial da soja no cerrado mato-grossense, particularmente no sudeste do estado, desde suas pré-condições à atualidade, buscando como pressupostos dos processos constituidores a herança histórico/territorial, econômica e localizacional que vem se estruturando ao longo de mais de 3 décadas, iniciado no período de 1970, mais especificamente, a partir de meados deste, qual ocorreram as mudanças político/territorial/local/global mediadas pelas mudanças socioeconômicas brasileiras. Assim, a tese está fundada no período em que se deu a divisão do estado, cuja situação colocou Rondonópolis e região em posição privilegiada, passando de área secundária a prioritária para a soja, situação cujas bases podem ser atribuídas à herança histórica de apropriação territorial e produção agropecuária iniciada no período 1950/1960. Nesse sentido, justifica-se nosso caminho teórico-metodológico que nos permitiu ver e compreender melhor a realidade atual, qual seja, o da busca da herança histórico/geográfica na produção da localização, visando os processos localmente (re)construídos em suas especificidades. Deve-se considerar o papel do Estado como imprescindível no processo de desenvolvimento da soja: sua introdução, consolidação e diversificação, seja produzindo o território e/ou como parceiro no processo de construção das infraestruturas e constituição desse ambiente produtivo. O impulso modernizador e urbanizador inaugurado com chegada da soja, a partir de suas pré-condições, ao atribuir posição de destaque a Rondonópolis no contexto da modernização agrária do cerrado mato-grossense, a partir da sua região, fez surgir cidades a partir da soja, especialmente Primavera do Leste e Campo Verde, como dois fortes e característicos exemplos que representam seu surto modernizador cidade/campo, resultando no processo de valorização territorial, cuja paisagem, sobretudo a urbana, demonstra de forma característica as contradições socioespaciais da lógica da acumulação capitalista com base na propriedade da terra, concomitantemente à exclusão de grande parte da população do direito desta. O processo, assim, é marcado pela (re) estruturação desta cidade no âmbito de atendimento da demanda de produção e expansão da soja numa atribuição de progressiva importância local, regional e até extra-regional, destacando como situações inerentes ao seu papel: o mercado de trabalho, a pesquisa e tecnologia, a indústria, comércio e serviços especializados, o marketing como discurso, as atribuições em perspectivas e a gestão política da localização, esta última, perpassando as demais, uma vez que significa a força da elite local, de forma que Rondonópolis está sendo promovida cabeça de rede urbana desse modelo econômico implantado no cerrado mato-grossense conhecido como complexo da soja. A gestão política da localização, na atualidade e, em perspectiva, é exercida no sentido do adensamento da logística dos transportes rodo/ferroviário com todo o incremento de investimentos que já são vislumbrados. Palavras-Chaves / The intent of the present research is to analyze Rondonopolis citys role in the soil territorial net expansion in Mato Grossos brazilian cerrado, particularly in the southeast of the state, since its pre-conditions to nowadays, establishing as assumptions for the constitutional processes the historical-territorial, economical and locational heritage, that has been structured over the last three decades, since 1970 more specifically, with the political/territorial/local/global changes, mediated by brazilian socioeconomical changes. Thence, the thesis is founded in the period when the state´s division happened, situation that raised Rondonopolis and region to a privileged position, going from a secondary area to soil priority, whose bases are possibly originated in the historical heritage of territorial appropriation and agropecuarial production initiated in the 1950/1960 period. In this way, our theoretical-methodological means are justified, what allowed us to better see and comprehend the present reality, which is the search for the historical-geographical heritage in localization production, looking for the locally reconstructed processes, in its specificities. It is necessary to consider as essential the States role in soil developments process: its introduction, consolidation and diversification, rather producing the territory and/or as partner in infrastructures construction and constitution of this productive environment process. The modernizing and urbanizing impulse initiated with the soil arrival, since its pre-conditions, when attributed marked position to Rondonopolis in Mato Grossos brazilian cerrados agrarian modernization context from its region, originated soil based cities, remarkably Primavera do Leste e Campo Verde, two strong and characteristic examples, that represent the modernizing city/field burst, resulting in the territorial valorization process, whose landscape, specially urban, demonstrates, in a characteristic way, the capitalist accumulation logics sociospacial contradictions, based in ground property, simultaneously to the exclusion of the major part of population from its rights. The process, thence, is marked by the (re)structuring of this city in the production demand supplement and soil expansion scope, in an attribution of progressive local, regional and even extra regional importance, having, to its role, the following inherent elements: the work market, research and technology, the industry, business and specialized services, the marketing as speech, the attributions in perspectives and localizations political management. This last one surpasses the others, once it represents the local elite strength, in a way that Rondonopolis is being promoted to head of the urban net of this economical model implanted in Mato Grossos brazilian cerrado, known as the soil complex. The localizations political management, these days and in perspective, is applied in the sense of road and railroad transportation logistic thickening, with the increment of all the investments already foreseen.

Responsabilité civile et neutralité de l'internet. Essai de conciliation / Civil liability and net neutrality. Conciliation proposal

Tourette, Alexandre 07 December 2015 (has links)
Il est bien connu que la responsabilité civile appliquée aux intermédiaires techniques de l’internet gouverne bien au-delà de ses destinataires directs. Par le biais de sa fonction normative, elle peut inciter les fournisseurs d’accès et les hébergeurs à restreindre la liberté des utilisateurs du réseau. Pour cette raison, la loi a limité leur responsabilité dès le début des années 2000. Alors que le régime de responsabilité qui en découle est régulièrement au cœur de l’actualité juridique, la neutralité de l’internet fait aujourd’hui l’objet de toutes les attentions. Ce concept émergeant est présenté, tour à tour, comme la condition de la liberté sur le réseau et comme le complice des pires excès. À l’heure où sa consécration légale est proposée avec insistance, il apparaît indispensable de s’enquérir de ses interactions avec une responsabilité civile qui s’inscrit, depuis les origines, au cœur du « droit de l’internet ». La présente recherche illustre, qu’au-delà d’une opposition apparente, les deux concepts peuvent s’enrichir l’un l’autre, pour peu que l’on en fasse une lecture raisonnable. Dans cette optique, les limitations de responsabilité dont bénéficient les intermédiaires techniques épousent les contours de la neutralité. La responsabilité civile appliquée à l’internet s’en trouve éclairée d’un nouveau jour. En retour, la neutralité acquiert une considération pour les dommages qu’elle cause. Elle y gagne un caractère raisonnable qui lui était, jusqu’ici, inconnu. L’espoir est alors permis que, loin du concept destructeur parfois dénoncé, la neutralité de l’internet contribue à équilibrer les relations tumultueuses entre libertés et responsabilité sur le réseau. / It is widely known that the civil liability applied to internet intermediaries governs well beyond its direct recipients. Through its normative function, it can encourage hosters and internet service providers to restrict freedom of network users. For this reason, the law limited their liability in the early 2000s. While this system of liability is regularly at the heart of legal news, the net neutrality is now the subject of all attention. This emerging concept is presented, alternately, as the condition of freedom on the network and as an accomplice of the worst excesses. At the time when its legal consecration is suggested with insistence, it is essential to inquire about its interactions with civil liability recorded at the heart of the "internet law". This study demonstrates that, beyond an apparent opposition, the two concepts can be enriched each other, as long as we make a reasonable reading. In this context, the limitations of liability of the technical intermediaries are close to fit with neutrality. It sheds a new light on the civil liability applied to the internet. In return, neutrality becomes a consideration for the damage it causes. It earns a reasonable characteristic that was unknown so far. Far from a destructive concept often denounced, we can hope that the neutrality of the internet helps balance the tumultuous relationship between freedom and responsibility in the network.

Modifications of perineuronal nets to regulate plasticity

van't Spijker, Heleen Merel January 2019 (has links)
Modifications of perineuronal nets to regulate plasticity Heleen Merel van 't Spijker Perineuronal nets (PNNs) are macromolecular structures formed by neurons after closure of critical periods of plasticity. During development, the central nervous system (CNS) goes through critical periods of plasticity; a period when substantial changes occur to adapt to the environment, during which many synapses are formed and also discarded. When a region of the CNS has finished its development and reached an efficient neuronal circuit, the capacity for plasticity needs to be reduced to preserve the formed circuit. PNNs are formed around neurons during this period of reduced plasticity. PNNs consist of a backbone of hyaluronan, bound by chondroitin sulfate proteoglycans (CSPGs). Here, I present my studies on the possible modifications of PNNs to regulate plasticity. Firstly, I have investigated the potential use of 4-methylumbelliferone (4-MU) to reduce PNN formation in vivo. 4-MU reduces the formation of hyaluronan. Since hyaluronan is the backbone of PNNs, I hypothesized 4-MU treatment would reduce PNN formation. For this study, I developed a method to orally administer 4-MU to rats. Subsequently, I investigated whether 4-MU treatment can improve recovery of rats after spinal cord injury, both with behavioural tests and with immunohistochemistry. Secondly, I have investigated a new binding partner of PNNs, neuronal pentraxin 2 (Nptx2). Nptx2 is secreted by neurons and regulates AMPA receptor diffusion. Nptx2 knockout mice show a prolonged critical period of plasticity in the visual cortex. Here, I have identified Nptx2 as a new binding partner of PNNs. Nptx2 is found in isolated PNN protein preparations and is removed from the surface of neurons by digestion of PNNs with chondroitinase ABC. I also determined Nptx2 facilitates PNN formation in vitro. Addition of Nptx2 to the medium of cortical neurons leads to an increase of neurons that start to form PNNs, as well as an increase in size and density of PNNs. These findings indicate Nptx2 may be used as a modulator of PNNs. Thirdly, I investigated the interaction between Nptx2 and PNNs. I developed a sandwich ELISA to determine which glycan chains from PNNs bind to Nptx2. Nptx2 binds to chondroitin sulfate E and hyaluronan. To investigate the binding properties of Nptx2, I performed quartz crystal microbalance with dissipation monitoring for Nptx2 films. Furthermore, I developed crystals of purified Nptx2 and hyaluronan for x-ray crystallography. The here presented results provide new insights in potential approaches to modulate PNN formation. Both lines of research provide a further understanding of the factors which regulate PNNs and may allow for the development of treatments for PNN related disorders.

Historical Study of Net Migration for Utah, 1870-1960

Huntsman, Rulon J 01 May 1968 (has links)
This is an historical study of the volume and direction of intercensal net migration for Utah, from 1870 to 1960. Some of the demographic characteristics of net migrants are also estimated and some inferences of the impact of net migration on Utah's socio-economic development is considered. Of necessity, indirect methods of migration estimation are used. Those used are: (1) Place-of-birth method, (2) Census survival ratio method and (3) Place-of-birth census survival ratio method. The results of this study reveal, for the first time, detailed demographic characteristics as to the age, sex and origin of the net migrants for Utah from 1870 to 1960. Such knowledge can prove useful in intrepretations of Utah's history and in extrapolating future trends.

Optimering av prestanda och utnyttjande av flertrådsteknik / Optimization of performance and utilization of multithreading

Gustafsson, Daniel, Öberg, Christoffer January 2009 (has links)
<p>The purpose of this thesis was to help the company Medius AB with optimization of selected parts in an existing system to minimize the execution time by implementing multithreading. The idea was to manipulate the code so that calculations could be executed at the same time. The main work in this thesis consisted of three optimizations. The first one was to reconstruct a big “for-loop” so it would execute every loop's work in an own thread. The second optimization also was a reconstruct of a “for-loop” so it could execute the work in different threads. The third and last optimization consisted of reconstructing a stored procedure on the database, so different parts of it each could be executed in an own thread to create data at the same time. To implement the optimizations Visual Basic .NET and its support for multithreading and connection-pools was used. The result of the optimizations meant that one of the modules could be executed more efficiently and it was 12 % faster. The other modules execution time was more efficient by 25 % faster. The meanings and requirements for this thesis are fulfilled by now letting the system make use of its resources in a better way.</p>

Towards Formal Verification in a Component-based Reuse Methodology

Karlsson, Daniel January 2003 (has links)
<p>Embedded systems are becoming increasingly common in our everyday lives. As techonology progresses, these systems become more and more complex. Designers handle this increasing complexity by reusing existing components (Intellectual Property blocks). At the same time, the systems must still fulfill strict requirements on reliability and correctness.</p><p>This thesis proposes a formal verification methodology which smoothly integrates with component-based system-level design using a divide and conquer approach. The methodology assumes that the system consists of several reusable components. Each of these components are already formally verified by their designers and are considered correct given that the environment satisfies certain properties imposed by the component. What remains to be verified is the glue logic inserted between the components. Each such glue logic is verified one at a time using model checking techniques.</p><p>The verification methodology as well as the underlying theoretical framework and algorithms are presented in the thesis.</p><p>Experimental results have shown the efficiency of the proposed methodology and demonstrated that it is feasible to apply it on real-life examples.</p> / Report code: LiU-Tek-Lic-2003:57.

Utveckling av design till mötesplats på Internet

Nordstrand, Victor, Eklöf, Johan January 2007 (has links)
<p>Ett community är en mötesplats på Internet där människor kan hålla kontakt, lära känna nya människor, diskutera osv. Det finns idag en mängd olika communities med många olika inriktningar. Communityn är idag mycket populära sidor på nätet och vissa har enormt mycket besökare och tjänar stora pengar. Det kan därför vara svårt att locka medlemmar om inte communityt innehåller nyheter som inte redan finns. Målet med det här arbetet har varit att skapa en tilltalande och användarvänlig design till ett community med ett sommar, fest och rese- tema. Delvis används en enkätundersökning för att ta reda på hur viktig det är med en design som sticker ut för att locka medlemmar. Resultatet av arbetet har blivit att en design med ett tema till sommar, fest och resor har skapats. Designen går i huvudsak i färgerna gul, blå och vit. Designen är till största del uppbyggd av CSS, ASP.NET och HTML.</p>
