Lergjord is a thesis that puts emphasis on the possibility of innovation by using local biobased material in the building industry of Skåne in Sweden. The thesis examines if rammed earth can be used in the implementation of LFM30 (Translated into English: Local Sustainable Goals in Malmö by 2030). By use of qualitative research methods, views on rammed earth as a building technique was explored by three stakeholders. This research has concluded if rammed earth is possible in Skåne as a conventional material in the future. We (Ludvig Dovberg and Tobias Löfgren) have examined the practical aspect of rammed earth on Urban Living Lab in the municipality of Lund by the use of local clay material from excavation for an expansion of a new railway between Malmö and Lund in collaboration with Trafikverket. This thesis concludes that rammed earth is feasible with clay from the excavation masses through project LERGJORD. Also, due to the vast quantity of it the resource might be useful for future rammed earth projects in Skåne. However, the building technique itself has some major drawbacks such as time-consumption and the knowledge gap is easily addressed. Although, there has been a development of a pre-fabrication concept of the building technique in Germany since the late 1990s, that could be a solution to the problem. The thesis also concludes that  higher education and research is compulsory to establish a knowledge base for architects to work by. The case study showcased that a standardization of the material is needed to prevent vast material testing before being accepted for construction, like the Lehmbau-praxis in Germany. According to the material’s low impact in CO₂-emission and circularity this resourceful extraction could be of interest by the members of LFM30 to implement in the building industry of Skåne. / Lergjord är ett arbete som undersöker möjligheten till innovation genom att utnyttja lokala biobaserade material i Skåne i Sverige. Arbetet undersöker om stampad jordbyggnad kan användas för att genomföra de Lokala Färdplansmålen som Malmö Stad sätter fram till år 2030 (förk. LFM30). Genom kvalitativa forskningsmetoder undersöktes stampad lerjord som byggnadsteknik hos tre intressenter. Studien har sammanfattat möjligheten om hur stampad lerjord i Skåne kan bli ett konventionellt byggmaterial i framtiden. Vi (Ludvig Dovberg och Tobias Löfgren) har utvärderat den praktiska aspekten i stampad lerjord på Urban Living Lab i Lund med användandet av lokal lerjord från utgrävningar av tillbyggnation för järnvägsspår mellan Malmö och Lund i samarbete med Trafikverket. Arbetet visar att stampjordstekniken är möjlig med utvunnen lera från schaktmassorna mellan Lund och Malmö med hänvisning till projekt LERGJORD. Med tanke på den stora kvantitet av lera som finns kan denna utvinning vara användbar för andra projekt i Skåne. Hursomhelst, byggtekniken besitter på utmaningar såsom tidskrav och kunskapsluckan är tämligen lätt att adressera. Trots det, har ett prefabriceringskoncept inom byggtekniken utvecklats sedan slutet på 1990-talet i Tyskland, som kan vara en lösning på problemet. Arbetet tyder också på att högre utbildning och forskning krävs för att etablera en kunskapsbas som arkitekter kan arbeta vidare på. Fallstudien visar på att en standardisering av materialet krävs för att undvika långa och omständliga materialtester innan godkännande för konstruktion, likt Lehmbau-lagstiftningen i Tyskland. Materialets låga klimatpåverkan och cirkularitet gör det relevant för LMF30’s medlemmar att se vidare på alternativet för implementering i den skånska byggindustrin.

When skeletal fractures are too extensive for fixation with plates and screws, autografts are the most used technique for treating this. Within the biomedical field the interest in biodegradable implants made from additive manufacturing have increased. Magnesium alloys has also gained interest because of its favorable mechanical properties.. The objective of this project is to report on new knowledge, possibilities and limitations of powder bed fusion-laser beam (PBF-LB) printed magnesium-based alloys for biomedical applications, specifically the mechanical properties of WE43. Before the practical work was carried through, a gathering of literature from scientific papers was put together to a background with information regarding Magnesium, additive manufacturing, microscopic observation methods and mechanical testing.  The practical elements were divided into 4 different categories: printing, sample preparation for observation and testing, microscopic observation, and mechanical testing. All the collected data was observed and discussed, and lastly compiled in to a result with microscopic images, stress-strain curves and data tables. It was discovered that the mechanical properties differed between the two build orientations. The specimen most appropriate for load bearing implants was the horizontal build direction. The differences between 67° and 90° scan strategy were that the 90° scan strategy with horizontal build orientation showed the lowest Young´s modulus which is favorable, whereas the 67° scan strategy showed higher tensile strength and ductility which also is favorable. Thereby no conclusion could be drawn on whether a 67° or 90° scan strategy was preferable. The conclusion was made that a horizontal build orientation had the most optimal mechanical properties, and that more research needs to be conducted on this topic before it can be used for biomedical applications.

Rapid rate of digitalization, emerging financial technology and changes in consumer behaviour have begun to transform the existing paradigm in the financial industry. Incumbent banks have found it difficult to keep up with this change however and are now faced with the challenge of deciding on what digital financial services build internally, buy externally or develop through partnerships. This study attempts to get a general overview of what factors traditional Swedish retail banks need to consider before deciding on a build, buy or partner strategy in order to digitize their financial services offering. This is done through a case study, where the empirical data consists of interviews with the retail division of a Swedish bank looking to digitize their securities trading offering as a response to a transforming industry. A few interviews were also conducted with people outside of the bank to increase the generalizability somewhat. The findings of the study identified 16 factors to be considered by traditional banks when faced with the challenge of deciding on whether to build, buy or partner in order to digitize their securities trading offering. Out of these, 9 factors were deemed to be especially important; Sustainable Competitive Advantage, Flexibility, Uncertainty, Supplier/Partner Relationship, Economies of Scale, Specialized Resources, Integration, Asset Specificity and Regulation. Several of the factors identified were shown to influence the build, buy or partner decision both positively and negatively and their impact should therefore be carefully evaluated and weighed against each other by managers before making a final decision on a build, buy or partner strategy. / Ökad digitaliseringstakt, ny finansiell teknologi och förändringar i kundbeteenden driver på en transformering inom finansindustrin. Traditionella banker har haft svårt att följa med i denna utveckling, och ställs nu inför utmaningen att bestämma vilka digital finansiella tjänster de bör bygga internt, köpa in externt eller utveckla tillsammans med en extern aktör genom ett partnerskap. Denna studie syftar till att få en generell överblick över vilka faktorer som svenska storbanker behöver överväga innan de beslutar sig för en bygg-, köp- eller partnerstrategi för att digitalisera sitt erbjudande av finansiella tjänster. Detta görs i form av en case studie, där den empiriska datan till största del består av intervjuer med nyckelpersonal från en svensk bank som ingår i ett projekt att försöka digitalisera deras värdepappershandelserbjudande som ett svar på en industri i förändring. Ett fåtal intervjuer genomfördes också med personer utanför banken för att öka generaliserbarheten av studien något. Resultatet av studien identifierade 16 faktorer som bör övervägas av traditionella banker som ställs inför beslutet om att bygga, köpa eller ingå i ett partnerskap för att digitalisera sitt värdepappershandelserbjudande. Av dessa anses 9 faktorer vara särskilt viktiga; Långsiktiga Konkurrensfördelar, Flexibilitet, Osäkerhet, Leverantörs-/Partnerrelation, Stordriftsfördelar, Specialiserade Resurser, Integration, Funktionsspecificitet och Regelverk. Resultatet indikerar också att flera av de identifierade faktorer kan påverka beslutet om en bygg-, köp- eller partnerstrategi både positivt och negativt. Deras påverkan bör därför utvärderas noggrant och jämföras mot varandra innan ett slutligt beslut tas gällande en bygg, köp eller partnerstrategi.

I detta examensarbete utförs en jämförande analys av metoder och verktyg för hantering och analys av data inom datalager. Med den snabbt ökande mängden data och utvecklingen av molnteknologier står företag inför utmaningen att navigera bland olika metoder för att välja den mest lämpliga för sin specifika datahantering och analysbehov. Rapporten belyser metoden One Big Table (OBT) samt verktyget Data Build Tool (dbt) och undersöker deras för- och nackdelar i datalagermiljöer. För att få en djupare förståelse för deras funktion och effektivitet jämförs de i olika användarfall genom prestandatester på latens och samtidighet med hjälp av verktyget Hyperfine. OBT implementeras med hjälp av Google BigQuery såväl som Google Cloud SQL för PostgreSQL där latens och samtidighet för analytiska målsättningar utvärderas genom användning av Python-skript med SQL-frågor respektive med dbt-modeller. Skripten och dbt-modellerna körs mot BigQuery samt PostgreSQL och de båda implementerar OBT. Resultatet visar att SQL-skripten uppvisade lägre latens än dbt-modeller när de exekverades mot både BigQuery och PostgreSQL. Ett annat fynd är att latensen för SQL-skripten var lägre i PostgreSQL jämfört med BigQuery, medan dbt-modellerna istället uppvisade högre latens i PostgreSQL jämfört med BigQuery. I båda datalagermiljöer visas det även att SQL-skripten presterar bättre än dbt-modeller vid samtidiga körningar. / This bachelor’s thesis presents a comparative analysis of methods and tools for data management and analysis within data warehouses. With the rapidly increasing volume of data and the development of cloud technologies, companies face the challenge of navigating various methods to choose the most suitable one for their specific data management and analysis needs. The report highlights the One Big Table (OBT) method and the Data Build Tool (dbt), examining their advantages and disadvantages in data warehouse environments. To gain a deeper understanding of their functionality and efficiency, they are compared in different use cases through performance tests on latency and concurrency using the Hyperfine tool. OBT is implemented using Google BigQuery as well as Google Cloud SQL for PostgreSQL, where latency and concurrency for analytical purposes are evaluated using Python scripts with SQL queries and dbt models. The scripts and dbt models are run against BigQuery and PostgreSQL, both implementing OBT. The results show that the SQL scripts exhibited lower latency than the dbt models when executed against both BigQuery and PostgreSQL. Another finding is that the latency for SQL scripts was lower when run against PostgreSQL compared to BigQuery, while dbt models showed higher latency when run against PostgreSQL compared to BigQuery. The SQL scripts also performed better than the dbt models in concurrent executions in both BigQuery and PostgreSQL.

Vid nybyggnation eller modernisering av fartyg installeras ofta avancerade integrerade övervakningssystem i maskinkontrollrum. Det är därför viktigt att de maskinbefäl som ansvarar för driften av fartyget innehar en utbildning och kunskap om hantering och felsökning av övervakningssystemen. Syftet med studien är att undersöka om maskinbefäl får tillräckligt med utbildning på nya integrerade övervakningssystemen för att utföra sina arbetsuppgifter på ett säkert och tryggt sätt. I den här studien har en enkät skickats ut till maskinbefäl ombord nybyggda fartyg där individerna får möjlighet att svara på hur de upplever möjlighet att genomgå utbildning och få kunskap över hur systemen fungerar. Studien visar att majoriteten av de tillfrågade befälen upplever att de innehar tillräcklig kunskap om övervakningssystemen för att kunna utföra sina arbetsuppgifter på ett säkert och tryggt sätt. Studien visar att majoriteten av befälen inte har blivit erbjudna en utbildning på systemen och att de som inte blivit erbjudna hade önskat få en utbildning. Studien visade att utbildningarna som erbjudits ofta är produktspecifika och inte installationsspecifika vilket gör att de inte upplevs som optimala då konstruktion och lösningar ofta avviker emellan installationer med samma produkter. Utbildning erbjuds av tillverkaren men ofta är det bara en liten del av maskinbefälen som erbjuds en plats. Studien visade också att de befäl som inte fick utbildning behövde tillskansa kunskaperna genom att själv utbilda sig ombord antingen i samband med avlämning eller under ordinarie drift. Slutsatsen är att maskinbefälen bör genomgå en utbildning innan de mönstrar på första gången och att det bör ges möjlighet till en uppföljande utbildning efter att besättningen arbetat med systemen en tid. För att avlösande besättningar ska kunna få möjlighet att sätta sig in och tillgodogöra sig kunskap om systemen bör mer tid ges vid avlösning. / During construction of new ships or modernization of ships, integrated automation systems is often installed in the engine control room. It is of importance that the responsible engine officers are familiar with how the system works and that they can perform troubleshooting if eventual faults occur. The aim of the present study is to investigate whether the engineer officer get enough training on new integrated surveillance systems to perform their duties in a safe and secure manner. In this study a questionnaire was sent to engine officers signed on new ships where they got the opportunity to give their answer how they experience the possibility to be trained and acquire knowledge how the systems work. The majority of the engine officers who answered the questionnaires felt comfortable to operate the ship safely. The study showed that the training courses offered often were product specific instead of installation specific, which was not optimal because there can be differences between construction and handling after installations of the same products. The survey showed that a majority of the officers had not been offered training on the monitoring system. The officers who were not offered training expressed a wish to be able to participate in training. Training on the system is offered by the manufacturer but often only a few of the engine officers is offered training by the shipping company. Earlier studies show that crews that participates in the building and delivery process on the shipyard or during installation of a new system receives training on site, the officers that come onboard as reliever after trial run, maiden voyage or during normal operation often have to learn by doing. The conclusion is that the officers should be given the opportunity to participate in training before signing on and also a follow up training course after working with the system for a while. To give the relieving officers a chance to familiarize themselves and assimilate knowledge of the system, there have to be more time available in conjunction with leave.

Diploma thesis deals with the issue of constructions on the land of another. At first the thesis focuses on definition of basic terms, i.e. the construction and the building plot. In the following text is concerned about permission to build. Attention is focused on three types of titles of use - lease, easement and of peripheral importance, loan of land, which is not given a full explanation, but only focusing on issues related to the topic of work. To the previous issues link two institutes which deal with third and fourth chapter - authorized and unauthorized construction. Authorized construction is current problem in the future and therefore it is very noticeable lack of explicit rules that must be compensated for general rules of unjust enrichment. The chapter on unauthorized construction is divided into sections according to the character of each "type", i.e. whether the construction is movable thing or realty and whether the authorization to construction lacked from outset or dropped out after the construction was built. Last but not least the work deals with public-law issues and also the role of public law in the formation of conditions for the rise of construction - in the chapter devoted to building plot, and also issues permission to build as a public-law act, which makes possible to...

Companies have put much focus on production systems to generate and maintain competitiveness which has contributed in less focus to logistics. The material flow is the process after the main processes and has therefore been regarded as “unimportant”. If the material flow fails, there can be consequences such as inventory-build ups or undersupply of material. Lean thinking is one strategy that may be applied to analyze and identify wastes, but the identification of problems has been harder to detect, while the ability to solve them has not improved at the same rate. Following two research questions has been asked to identify how companies should proceed to improve their inventory management but also what factors contribute to the inventory build-ups.  ·        What may cause excess inventory in manufacturing companies? <ul type="disc">How can a manufacturing company reduce WIP´s? The research method is based on a qualitative approach with an interpretivist research methodology to help answer the questions. A case study was done at a manufacturing company to help answer the research questions. The data has been collected by observations trough section B1 and unstructured interviews with both management and operators. The collected data was later compared to the literature according to the inductive reasoning to be able to make suggestions for improvements. The DMAIC tool has been a central point of this research regarding the mapping of the current state and suggestion of a future state. The case study was conducted at Company X AB in the middle of Sweden which is a company that manufactures components and complete solutions. The focus on production has resulted in less focus on the internal logistics. With the low focus on the internal logistics, inventory build-ups have occurred. The results point to the OEE being a contributing factor to the inventory build-up. The availability of both machines was low and therefore caused the OEE to be low. The low availability was caused by long changeovers, staff shortages, and emergency reparations. The conclusions are that Company X must make improvements so that the factors of the low availability decrease in frequency and severity to reduce the work-in-process (WIP). The improvements should be approached with different lean-tools such as SMED, KANBAN, FIFO and 5S.

Recently, the wavy leading edge airfoils, inspired by the humpback whale´s flipper, have been investigated, as flow control mechanisms, at low Reynolds numbers in order to improve aerodynamic performance in this particular flow regime. The overall aim of this work is to investigate the airfoil geometric effects on wavy leading edge phenomena in the low Reynolds number regime. Experimental investigations were carried out correlating force measurements with mini-tuft and oil visualizations in order to understand the airfoil thickness effects on wavy leading edge phenomena. Three sets of airfoil thickness were tested (NACA 0012, NACA 0020 and NACA 0030), each set consisting of smooth plus three wavy configurations (A=0.11c, ?=0.40c; A=0.03c, ?=0.40c and A=0.03c, ?=0.11c); Reynolds number was varied between 50,000 and 290,000. The results present many findings that were not possible in previous studies due the fact that these investigations were constrained to specific geometries and/or flow conditions. At higher Reynolds number, the decrease in airfoil thickness leads the airfoils to leading edge stall characteristics causing the lowest aerodynamic deterioration for the thinnest wavy airfoil as compared to smooth configuration in the pre-stall regime. In addition, the results show impressive tubercle performance in the lowest Reynolds number. For any tubercle geometry and airfoil thickness, the wavy leading edge airfoils present higher maximum lift values as compared to smooth configurations showing an unprecedented increase in performance for a full-span model tested in the literature. The flow visualizations present two flow mechanisms triggered by secondary flow: three-dimensional laminar separation bubbles and vortical structures. Regarding three-dimensional laminar bubbles, the results confirm some of the few previous experimental and numerical studies, and presents for the first time these structures as a very efficient flow control mechanism in the post-stall regime justifying the impressive increase in maximum lift in the lowest Reynolds number. Besides that, two characteristics of laminar bubbles, \"tipped-bubbles\" and \"elongated-bubbles\", are identified with different effects in the pre-stall regime. This thesis presents higher tubercle performance for thinner airfoils (NACA 0012) and/or lower Reynolds number conditions (Re=50,000) showing clearly that an optimum performance lead the \"tubercles\" to operate under conditions of leading edge flow separation conditions. Therefore, a design space for tubercles conducted to leading edge stall characteristics confirming the hypothesis of Stanway (2008) eight years before. / Recentemente, aerofólios com bordo de ataque ondulados, inspirados na nadadeira da baleia jubarte, tem sido investigados como mecanismo de controle de escoamento para baixo número de Reynolds com a finalidade de se aumentar o desempenho aerodinâmico neste específico regime de escoamento. O objetivo geral deste trabalho é investigar os efeitos geométricos do aerofólio nos fenômenos do bordo de ataque ondulado na condição de baixo número de Reynolds. Investigações experimentais foram realizadas correlacionando medições de forças com visualizações de lã e óleo a fim de compreender os efeitos da espessura do aerofólio sobre os fenômenos de bordo de ataque ondulado. Três conjuntos de espessura de aerofólios foram testados (NACA 0012, NACA 0020 e NACA 0030) na faixa de número de Reynolds entre 50,000 e 290,000, onde cada conjunto tem um aerofólio liso e três ondulados (A = 0.11c, ? = 0.40c; A = 0.03c, ? = 0.40c e A = 0.03c, 0.11c ? =0.11c). O dados experimentais mostram importantes resultados que não foram possíveis em estudos anteriores devido às investigações serem restritas à geometria ou/e condição de escoamento específicas. O resultados de medida de força mostram que a diminuição da espessura do aerofólio conduz às características de separação de escoamento de bordo de ataque que causam menor deterioração aerodinâmica nos aerofólios ondulados finos quando comparados aos lisos no regime de pré-stall. Além disso, os resultados mostram um desempenho destacado do bordo de ataque ondulado para condição de menor número de Reynolds. Em quaisquer espessuras de aerofólio, os bordos ondulados apresentam valores de sustentação máxima maiores quando comparado aos aerofólios lisos mostrando assim resultado inédito na literatura para modelos ondulados bi-dimensionais. As visualizações de óleo evidenciaram dois mecanismos de controle de escoamento desencadeadas pelo escoamento secundário: bolhas de separação laminar tridimensionais e estruturas vorticais. Os resultados confirmam alguns poucos estudos experimentais e numéricos anteriores relacionadas com bolhas tridimensionais, e apresenta pela primeira vez estas estruturas como um mecanismo muito eficiente de controle de escoamento em regime de pós-stall justificando o aumento de máxima sustentação para o menor número de Reynolds. Adicionalmente, foram identificadas duas estruturas de bolhas tridimensionais nomeados aqui como \"bolhas com pontas\" e \"bolhas alongadas\" que causam distintos efeitos no regime de pré-stall. Esta tese apresenta como resultado maior desempenho para aerofólios ondulados com menor espessura (NACA 0012) e/ou para condições de menor número de Reynolds (Re=50,000)mostrando claramente que estas características levam as ondulações a operarem em condições de stall de bordo de ataque assim tendo um desempenho superior. Portanto, um espaço de projeto para tubérculos conduz às características de stall de bordo de ataque confirmando a suposição de Stanway (2008) oitos anos antes.

Esse trabalho, estreitado com a linha de pesquisa do Programa de Pósgraduação em Geografia Humana, tem por objetivo maior indicar as transformações recentes ocorridas no espaço urbano da cidade de Tiradentes - MG, ou seja, a partir da década de 1980. A fim de demonstrar isso, houve um estudo sobre a formação socioespacial da cidade ao longo do tempo - desde o século XVIII até 2005, incluindo aí a influência do turismo - que resgatou o dinamismo econômico local após os anos 1960. Desse modo, Tiradentes passa a receber investimentos públicos e privados que incrementam o turismo e, assim, atraem os imigrantes; valorizam seus terrenos e imóveis; transformam o Centro Histórico cada vez mais numa região de comércio e em processo de gentrificação; expandem intensamente a cidade, desde a década de 1980, através de loteamentos nos bairros. Nesse contexto, o trabalho é finalizado com as perspectivas da expansão urbana que estão se formando em Tiradentes. / This research beside the Post-Graduation Program in Human Geography line has as a greatest proposal to indicate the most recently transformation at the urban space of Tiradentes-MG, after the eighties. In order to prove that , a study was made about the sociospace build-up of the city through the years since the eightieth century until 2005, including tourism influence that brought back its economic dynamism of the place after the sixties. By the way, Tiradentes begins to receive public and private investiments increasing the tourism in the city, absorbing migrant people, raising the value of real properties. The Historical Center becomes more and more on a trade region and in gentrification process and new plots of land at the neighborhood shows the intensity expansion of the city since the eighties. On this context, the research ends revealing the perspectives of urban expansion that are taking shape in Tiradentes.

Essa pesquisa teve como ponto de partida a ameaça de extinção de um espaço que reúne seis campos de futebol de várzea na cidade de São Paulo. Trata-se do Complexo de Campos de Futebol do Campo de Marte, instalado em um terreno que há décadas é disputado pela Aeronáutica (União) e pela Prefeitura da cidade. Inicialmente, buscou-se articular esse conflito específico a uma questão mais ampla: o que fazia com que o futebol de várzea, prática cuja trajetória é marcada pelo fim de vários de seus espaços, continuasse ocupando um papel relevante como modalidade de lazer e associativismo popular na cidade de São Paulo? Partindo da perspectiva dos varzeanos que construíram os seus campos nesse terreno a partir dos anos 1960 e que, desde então, lidam com a possibilidade de terem que deixar esse espaço, chegou-se a apreensão de uma lógica interna que rege essa prática e sua profunda conexão com o contexto social em que se inserem. O futebol de várzea, para esses varzeanos, só seria viável pela abnegação de seus personagens, uma postura necessária para a conquista e manutenção de um universo que se constrói, sobretudo, a partir de ações de autoconstrução e de constantes negociações. Tanto em sua dimensão espacial, onde a figura do abnegado ocupa um papel central por resolver, dentro de seu clube e no campo varzeano como um todo, muitas das questões impostas pela política do Estado de não proporcionar o direito ao lazer e ao esporte, assumindo, por um lado, as vezes de instância auto reguladora, e por outro, de provedor de infraestrutura e mediador de interesses. Como em sua dimensão esportiva, onde sem a presença de uma instituição ou entidade que tenha se estabelecido ao longo de sua trajetória como organizadora e reguladora dessa prática, essa tarefa foi levada a cabo pelos próprios varzeanos a partir de múltiplas alianças e referências. / This research had as a starting point the threat of extinction of a space that gathers six football fields of várzea in the city of São Paulo. It is the Complexo de Campos do Campo de Marte, installed in a land that has been disputed for decades by the Aeronautics (Union) and by the town council. Initially, we tried to articulate this specific conflict to a broader question: what made várzea football, a practice whose trajectory is marked by the end of several of its spaces, continued to play a relevant role as a leisure modality and popular associativism in Sao Paulo City? Starting from the perspective of the Varzeans who built their fields on this terrain from the 1960s onwards, and since then they have dealt with the possibility of having to leave this space, we came to the apprehension of an internal logic that governs this practice and its deep the social context in which they are inserted. Várzea football, for these Varzeans, would only be viable due to the abnegation of their characters, a posture necessary for the conquest and maintenance of a universe that is built, above all, by actions of self-construction and constant negotiations. Both in its spatial dimension, where the self-sacrificing figure occupies a central role within his club and the Varzean camp as a whole, many of the issues imposed by the State\'s policy of not providing the right to leisure and sport, , on the one hand, sometimes as a self-regulatory body, and on the other as an infrastructure provider and mediator of interests. As in its sporting dimension, where without the presence of an institution or entity that has established itself along its trajectory as organizer and regulator of this practice, this task was carried out by Varzeans themselves from multiple alliances and references.
