Diante do debate historiográfico que a atuação do PCB suscita, a pergunta que norteia nossa pesquisa é a seguinte: teria mesmo o partido buscado aliança tácita com a burguesia nacional? E isto o teria levado a ficar a reboque do trabalhismo? Diante disso, pareceu-nos muito mais a defesa tática da ordem para o fortalecimento da organização partidária do que propriamente uma “aliança”. Daí nossa hipótese de trabalho: a Teoria da Revolução Brasileira propugnada pelo PCB oscilou entre posições reformistas e revolucionárias e não obteve êxito, na prática, para levar adiante uma política autônoma, tanto nas fileiras internas como no seio da classe trabalhadora, ficando, indiretamente, a reboque do trabalhismo desenvolvimentista. Nossa conclusão é a de que, verifica-se, no entanto, que a política de alianças do PCB não era propositadamente de “reboquismo”. Os comunistas, ao longo do percurso histórico estudado, tiveram importantes êxitos táticos e lograram proeminência no seio da esquerda brasileira nos anos 1950. Defendemos também nesta pesquisa que a política de alianças dos comunistas teve como mote a via para o socialismo, em que pesem as enormes dificuldades de atuação dos seus membros, principalmente no período de clandestinidade. / The goal of this work is the PCB’s — Brazilian Communist Party — acting in the temporal hiatus of 1942 to 1958, i.e., from the Party’s reorganization during the New State of Getúlio Vargas to the XX Congress of the Communist Party of the Soviet Union (CPSU). Faced with the historiographical debate that emerges from the PCB’s acting, the question that guides our research is as follows: did the Party really intended to achieve a tacit alliance with the national bourgeoisie? And did this, if true, resulted in Party trailing behind Labourism? In light of this, it seemed to us much more a tactical defense of the order, to the strengthening of the Party’s organization, than strictly an “alliance”. From this emerges our hypothesis: that the Theory of the Brazilian Revolution put forward by PCB oscillated between reformist and revolutionary positions, failing to succeed, in practice, at realizing an autonomous policy, both in the internal ranks and in the core of the working class, staying, as result, indirectly trailed behind the developmental Laborism. We verify in our conclusion that, however, the alliances’ policy of the PCB wasn’t one intentionally “traillist”. The communists, over the studied historical period, had important tactical victories, achieving prominence inside the Brazilian Left in the 50’s. We also defend in this research that the communists’ policy of alliances had as motto the path to Socialism, a route side by side with the enormous difficulties in the acting of its members, especially when they were forced to go underground.

Durante seus 70 anos de existência, o PCB protagonizou uma luta pela democracia e pela própria sobrevivência, sofrendo diversas transformações que culminaram no seu X Congresso. Esta pesquisa pretende investigar qual a contribuição dessas transformações para a construção da democracia brasileira que por diversas vezes foi ameaçada, principalmente na ditadura de Vargas e na ditadura militar de 1964 a 1985. A luta pela democracia foi caracterizada por dois paradoxos: a autonomia versus a heteronomia em relação à URSS (adaptação do comunismo à cultura brasileira) e o paradoxo da luta insurreta versus a luta democrática, pacífica, por um governo socialista. Em razão desses paradoxos, o PCB foi enfraquecendo com o tempo, tendo basicamente dois causadores: 1º) as críticas que a teoria marxista-leninista vinha sofrendo no âmbito internacional e o próprio enfraquecimento do comunismo no mundo, que culminou com a queda do Muro de Berlim, em 1989, e com o fim da URSS, em 1991; 2º) os conflitos internos no partido decorrentes dos dois paradoxos citados, que fizeram diversos militantes importantes largarem a vida política ou o trocarem por outros partidos, além dos conflitos do Partidão com outros partidos. Concluiu-se que os conflitos internos e externos enfraqueceram o PCB, por um lado, mas, por outro, serviram como substrato para fortalecer a democracia no partido – tão defendida pelo PPS, um dos partidos que surgiram como resultado do X Congresso do PCB – e do país. Além disso, percebeu-se que faltou ao PCB uma análise aprofundada da realidade brasileira antes de tentar qualquer iniciativa em direção a uma revolução social que aumentasse a participação da sociedade civil na sociedade política. Para esse aprofundamento, sugere-se a utilização dos pensamentos de Gramsci, não necessariamente como método, mas pelo menos como referência de um estudo aprofundado de uma sociedade. ______________________________________________________________________________ ABSTRACT / After the Russian Revolution of October 1917, in 1922, was created in Brazil, the Partido Comunista Brasileiro (PCB), which, based on the dictatorship of the proletariat, has become an important component of Brazilian political history until 1992, when its X Congress decreed its end. During its 70 years existence of the PCB staged a fight for democracy and survival facing changes that culminated in its Tenth Congress. This study intends to investigate the contribution of these transformations for the construction of Brazilian democracy that was threatened several times. Especially in the Vargas dictatorship and the military dictatorship from 1964 to 1985. The struggle for democracy was characterized by two paradoxes: 1º) internationalism (influence of the URSS) versus nationalism (adaptation to Brazilian culture of communism); 2º) the paradox insurgent fighting the fight versus democratic, peaceful, for a socialist government. Because of these paradoxes PCB was fading with time, for basically two causes, the first criticism that the marxist-leninist theory was suffering at the international and own specific weakening of communism in the world which culminated in the fall of the Berlin Wall, in 1989, and the end of the USSR in 1991. The second were the conflicts within the party by the two paradoxes mentioned, who made several important people step out of politics life or go for other parties, besides the “Partidão” (the big party) conflicts with other parties. It was concluded that the internal and external conflicts that have weakened the PCB, on the other side served as a substrate for strengthening democracy in the party – as advocated by PPS, one of the parties that arise how result the X Congress of the PCB – and country. In addition it was felt that it lacked the PCB depth analysis of the Brazilian reality before attempting any move toward a social revolution that would increase civil society participation in political society. For further suggests that the use of Gramsci, not necessarily as a method, but as a reference for a study of a society. ______________________________________________________________________________ RÉSUMÉ / Après la Révolution russe d'Octobre 1917, en 1922, a été créé au Brésil, le Partido Comunista Brasileiro (PCB), qui, a fondé sur la dictature du prolétariat, est devenue une composante important de l'histoire politique brésilienne jusqua 1992, lorsque son dixième Congrès a décrétée sa fin. Au cours de ses 70 ans d'existence le PCB a organisé une lutte pour la démocratie et pour sa propre et metre une changements qui pandent sa dixième Congrès. Cette étude but à étudier la contribution de ces transformations pour la construction de la démocratie brésilienne qui a été menacé à plusieurs reprises. Principalment pendent la dictature de Vargas et la dictature militaire de 1964 à 1985. La lutte pour la démocratie a été caractérisé par deux paradoxes: 1º) internationalisme (influence de l'URSS) versus nationalisme (adaptation du communisme à la culture brésilienne); 2º) le paradoxe de la lutte insurgés versus lutte démocratique, pacifique, par un gouvernement socialiste. Principalement à cause de ces paradoxes le PCB a été affaibli pendent le temp, avec deux causes. La première la critique de la théorie marxiste-léniniste dans tout le monde et le affaiblissement du communisme dans le monde qui a été sa fin avec la chute du mur de Berlin, en 1989, et la fin de l'URSS en 1991. Les seconds motif sont les conflits au sein du parti par les deux paradoxes mentionnés, qui a fait plusieurs militant important changer de parti au abandonner la vie politique et les conflit du “Partidão” (le grand parti) avec les autres parties. Il a été conclu que les conflits internes et externes qui dun coté ont affaibli le PCB et d’outre côté est a été un substrat pour le renforcement de la démocratie dans le parti – a défendu pour le PPS, un des partis qui résultent du Dixiéme Congrès du PCB – et du pays. Il a a été conclu aussi que le PCB ne fait pas une analyse approfondie de la réalité brésilienne avant de tenter une révolution sociale qui augment la participation de la société civile dans la société politique. Pour sa analyse de la société, nous suggèrons l'utilisation de Gramsci, pas nécessairement comme une méthode, mais comme une référence.

Many factors affect membrane composition in ectotherms, including allometry, temperature, toxins such as PCB-153, and osmotic stress. This thesis seeks to describe the relationship between membrane composition, size, and phylogeny in twelve species of cypriniform fish; to describe interactions between the homeoviscous responses to temperature and to PCB-153 in goldfish and rainbow trout; and to describe the membrane response to hypoosmotic stress in goldfish. Commonalities in these patterns provide insight into shared mechanisms of phospholipid modulation. In particular, such similarities indicate whether the membrane pacemaker theory of metabolism, which connects allometric relationships between body size, membrane phospholipids, and metabolic rate, can serve as a general framework for understanding membrane composition. Chapter 2 investigates how cypriniform membrane unsaturation decreases with mass through different fatty acid substitutions than in endotherms, but these fatty acids are in turn shown to be due to the species’ relatedness to one another rather than to purely physiological causes. In Chapter 3, PCB-153 is shown to increase cholesterol in liver and brain, while high temperature primarily reduces phospholipid unsaturation. In Chapter 4, these patterns are further explored in trout. As in goldfish, cholesterol modulation is the primary response to PCB-153, whereas temperature primarily reduces phospholipid unsaturation. Trout show more pervasive fatty acid changes than goldfish in all tissues except the liver, which does not respond to PCB exposure, suggesting that PCB-153 pushes trout’s homeoviscous response to a limit that similarly-exposed goldfish do not face. Chapter 5 shows that goldfish intestines decrease membrane saturation; kidneys decrease membrane cholesterol; gills decrease neither; and muscles decrease both in response to long-term exposure to hypoosmotic conditions. The intestine and kidney are both involved in recovering ions from body fluids, but gills suppress ion loss and muscle concentrates ions from the bloodstream. Temperature, osmotic stress, PCB-153, and increasing body size are all addressed via a similar set of membrane responses in fish, which fits with the membrane pacemaker theory’s predictions regarding membrane composition, metabolic rate, and size.

The purpose of this thesis is to conduct an analysis of whether the printed circuit boards from Ericsson can be tested using an automatic probing system or what changes in the design are required, to be a viable solution. The main instrument used for analyzing the printed circuit board was an oscilloscope. The oscilloscope was used to get the raw data for plotting the difference between the theoretical and actual signals. Connected to the oscilloscope was a 600A-AT probe from LeCroy. The programs used for interpreting the raw data extracted from the oscilloscope included Python, Matlab and Excel. For simulations on how an extra via in the signal path would affect the end results we used HFSS and ADS. The results were extracted into different Excel sheets to get an easier overview of the results. The results showed that the design of a board must almost become completely rebuilt for the changes, and it is therefore better to implement in a new circuit board rather than in an already existing one. Some of the components have to either be smaller or placed on one side of the board, where they cannot be in the way of the probe. The size of the board will become larger since the rules of via placements will be limited compared to before. The most time demanding part was the simulations of the extra via in the signal path, and the results showed that if a single-ended signal is below two gigahertz the placing of the via does not make a big difference, but if the signal has a higher frequency the placement is mostly dependent on the type of the signal. The optimal placement is generally around four millimeters away from the receiving end. / Målet med detta examensarbete är att göra en analys av huruvida Ericssons kretskort kan testas med hjälp av ett automatiskt probe system eller om det kräver stora förändringar i designdelen av kretskorten och om, vad för förändringar det i sådant fall kan vara. Till hjälp att analysera kretskorten har vi haft oscilloskop för att få ut rådata om skillnaderna mellan de teoretiska och verkliga signalerna. För att kunna tyda oscilloskopets samplade signaler har olika programmeringsspråk som Python, Matlab samt Excel använts. En extra via i signalens väg har även simulerats i HFSS och ADS med olika sorts probar för att se hur signalens beteende påverkas. Resultaten extraherades sedan in i olika Excel ark för att få en lätt överskådlig bild av resultaten. Resultatet vi fick visade att utformningen av ett kretskort med ändringarna skulle vara lättare att göra med en ny design istället för en redan existerande då större delar av kortet skulle behöva göras om. Vissa stora komponenter behöver antingen göras om, hitta mindre men likvärdiga eller sättas på ena sidan av kortet där de inte är i vägen för proben. Kretskorten som kommer använda flygande probesystem kommer antagligen bli lite större då viornas placering är mer begränsade än tidigare. Det mest tidskrävande arbetet var att simulera olika placeringar av en extra via i signalens väg. Detta visade att på en single ended signal under två gigahertz så gör det ingen större skillnad vart i signalens väg som den extra vian placeras. Då en högre frekvens används så är själva signalens karaktär det viktigaste än placeringen av en via, men om man inte vet den exakta karaktären så är fyra millimeter bort från mottagarens sida att rekommendera då närmare placering av viorna gör att signalerna börjar störa varandra.

För att testa en befintlig anodiseringsutrustning behövde Prevas Development AB en elektronisk last som kunde simulera en resistans, med en loggfil som utgångspunkt. Detta åstadkoms genom en återkopplad regulator som styr en MOSFET. Dessutom används optisk isolering för att isolera styrelektronik från den höga spänningen från anodiseringsutrustningen. I rapporten redovisas de viktigaste valen och resultatet av test och utvärdering, samt områden för framtida förrbä ttring.

Fish and wildlife were randomly sampled in Utah from pre-selected x areas and analyzed for levels of total mercury, dieldrin, DDT, and DDE. Levels were well within consumptive tolerance or guildeline limits except for mercury levels of fish in Willard Bay Reservoir. PCB's were also identified in a large proportion of samples. None of the chukars, 6 percent of the pheasants, 4 percent of the waterfowl, and none of the fish sampled, excluding Willard Bay Reservoir, were above the 0.5 ppm guideline level for mercury established by the Food and Drug Administration. Seventy-seven percent of the fish sampled from Willard Bay Reservoir were above the 0.5 ppm guideline level. Only one duck (2 percent) was above the maximum permissible concentration for dieldrin. All of the chukars, pheasants, other waterfowl, and fish were well below human consumptive tolerance limits for dieldrin and DDT + DDE. It is recommended that studies be initiated to more closely define possible sources of mercury and the health hazard involved in consumption of these fish.
