Full textSix sweet chestnut (Castanea sativa Mill) coppices were studied in Hurepoix. The sample was constituted with 3 age classes and 2 site qualities. Their volume or biomass production was evaluated by linear ponderated regression method. At stational scale, square of individual circonference at breast heigth (Cbh) is sufficient to describe stand production (P). At regional scale, introduction of dominant heigth (Hd) improves the model : P = a. Cbh. Hd + b where a and b, regression parameters vary with coppices age classes. Complementary data about volume production concerning 8 more stands, allowed to establish the following model : V = a. G. Hd + b where V is the stand volume, G its basal area and Hd its dominant heigth. Such a model could not be established for biomass because of lack of data. A production index wich allowed comparison between stations (age independant) was definied as the stand dominant heigth at age 10. Stational characteristics, mainly edaphic factors, were studied. Macroelement foliar analysis were made. Mineral characteristics vary a lot between the different stations. A reduced nitrogen disponibility was observed for two of the less productive stations. Luminous climate index explains either a part of production variations. On the sample studied, soil aeration seems important

Full textPseudomonas aeruginosa (Pa) is a Gram-negative bacteria frequently involved in healthcare-associated pneumonia and considered as a « problem-pathogen ». To face the announced post-antibiotic era due to increasing resistance and lack of new antibiotics, new treatment strategies have to be developed. During pneumonia, lung injury results from both bacterial-mediated virulence and host response. Modulation of an overreacting host response could be an alternative therapeutic target in Pa-induced lung infection. Kynurenines are small molecules resulting from tryptophan degradation with reported immunomodulatory properties. Pa is known to produce kynurenine, but the functional enzymes, types and amounts of secreted metabolites are poorly known. Interestingly, many host cells also possess the kynurenine pathway, whose metabolites are known to control immune system homeostasis. The following experiments aim to determine whether bacterial metabolites can interfere with the host’s immune response, leading to a possible immunomodulatory interplay between bacteria and host kynurenine pathways, impacting on the pathophysiology of P. aeruginosa infection. To that goal, we use a murin model of acute lung injury. Mice were infected with WT strain of Pa, compared to mutant strains unable to produce kynurenine (ΔkynA), and mutant strains overproducing them (ΔkynU). Moreover, we studied the interactions between bacterial and host kynurenine pathways by inhibiting the first enzyme of the host pathway called indoleamine-2,3-dioxygenase (IDO). Finally, we assessed the role of the arylhydrocarbon receptor (AhR), a known receptor to kynurenine involved in lung immunity, using AhR KO mice. First, we assess types and levels of metabolites produced by Pa in an in vitro model, and the relevance of this production in vivo. We show for the first time that Pa is able to secrete kynurenine at clinically relevant levels, and other metabolites such as kynurenic acid and 3 OHkynurenine, what was unknown to date. Second, we show that bacterial metabolites were able to modulate the host innate immune response, by increasing alveolar recruitment of neutrophils, associated with decreased inflammatory cytokines levels and impairment of antigen-presenting cells activation. Finally, we report that IDO and AhR are involved in this kynurenine-mediated immunomodulation. These data suggest that pulmonary infection with a bacteria highly expressing the kynurenine pathway enzymes could lead to an imbalance in the immune response to infection, thus constituting a potential therapeutic target to improve Pa-induced pneumonia outcome
Kazic, Dusan. "Plantes animées. De la production aux relations avec les plantes." Thesis, Université Paris-Saclay (ComUE), 2019. http://www.theses.fr/2019SACLA027.
Full textThis thesis deals with animated relationships between peasants and their plants in French fields. For some, plants are sentient and intelligent beings, for others they are working beings, accompanying beings, game beings, suffering beings. Some peasants speak to their plants, others weave loving relationships, and let their plants teach them how to cultivate them in the fields. In describing these relationships, the thesis shows that, thanks to the sensitive relations that these peasants weave with their plants, they animate them by leaving naturalist epistemologies aside. By taking these words seriously, literally, the thesis defends the hypothesis that, in order to prevent the agricultural world from becoming ruins, we must no longer seek to "produce differently", but we must break with the paradigm of production to anchor peasants and their plants in co-evolutionary relationships. By plunging into the history of modernity, that is to say by revisiting the conflict between the peasant world on one side and the modern world on the other, with the arrival of the physiocrats among the French intellectual and policy-making bodies, this thesis shows that the concept of production is based on a universalist and naturalized approach that has been imposed without any empirical basis in the agricultural world and in the modern world more widely

Essa pesquisa tem como objetivo analisar como as imagens foram empregadas, desde o início da Idade Média até os tempos do capitalismo tardio, por diferentes instâncias de poder com a intenção de atender a fins de caráter propriamente político, e consequentemente ideológico. Nossa intenção é mostrar em que medida as imagens foram pensadas para serem implementadas em diferentes épocas como se pudessem supor uma neutralidade visual acerca da realidade, sem que fossem notadas como uma das formas de ferramenta de controle. Isto é, uma ferramenta de controle político pelo qual uma cultura dominante representa o mundo, torna-o presente e age sobre ele. Da crítica a respeito da construção do mito sobre a imagem na história, compreendemos que ela tendeu a negar sua origem real e sua natureza de objeto fabricado para se afirmar como um artefato quase consubstancial a seu protótipo sagrado. Longe de uma neutralidade, é preciso afirmar a noção de que as imagens exercem um controle social sofisticado a partir de seu uso em razão de uma política voltada para um posicionamento ideológico específico da cultura dominante de uma determinada época. Por esse motivo acreditamos que as imagens foram e continuam a ser utilizadas como arma propagandística na legitimação da cultura hegemônica. Lembramos que a luta política é uma luta pelo poder de representação, pelo reconhecimento das formas de representação legítima e pelo controle simbólico. E o poder simbólico é o poder econômico, político e cultural que está em condição de se fazer reconhecer e de obter reconhecimento. Portanto, nossa proposição se localiza na discussão do sentido simbólico da imagem gráfica enquanto código fundamental, que é operado pelas instâncias de dominação para o controle das massas em função da ideologia particular de seu tempo histórico. E por instâncias de dominação supomos o Campo do Design, que através de princípios e esquemas específicos consagram as imagens que atendem a sociedade como um todo. Nesse sentido, a pesquisa chama atenção para a forma como se organizam as representações de conhecimento sobre a sociedade, mostrando que isso implica em incorporar à análise todos os aspectos das organizações das quais elas são feitas, incluindo: estruturas burocráticas, poder financeiro, a cultura visual, os códigos profissionais, enfim, todas as condições econômicas, culturais e políticas de desenvolvimento e acesso que determinam o que, e de que maneira uma imagem será representada para a sociedade.
This research is aimed at analyzing how images have been used by different instances of power with the intention of attending purposes of political and, consequently, ideological character since the beginning of the Middle Ages until the times of late capitalism. Our intention is to show to what extent images have been planned to be implemented at different moments as if they could assume a visual impartiality on reality, without them being noticed as instruments of control. That is, an instrument of political control through which a dominant culture represents the world, makes it present and acts upon it. From the critics on the construction of the myth about image in history we understand that the image has tended to deny its real inception and its nature as an object which has been fabricated to affirm itself almost as an artifact which is consubstantial to its sacred prototype. Far from what we may call impartiality, we must take into consideration that images exercise a sophisticated form of social control from its usage on account of politics directed to a particular ideological stance of the dominant culture in a certain time. For this reason we believe that images have been and continue to be used as a propagandistic tool in the process of legitimating the hegemonic culture. We point out that the political struggle is an effort over the power of representation, over the acknowledgement of the forms of legitimate representation and symbolic control. Symbolic power is the economic, political, and cultural power that is in position of making itself recognized and obtaining recognition. Therefore, our proposition stands on the discussion of the symbolic meaning of the graphic image as a fundamental code that is run by the domination instances aimed at controlling the masses according to the particular ideology of their historical time. By domination instances we suppose the Field of Design, which, through principles and specific patterns, consolidates images that attend society as a whole. In this sense, our research highlights the manner through which representations of knowledge are organized on society,demonstrating that this implies incorporating to our analysis all aspects of the organizations of which they are made including bureaucratic structures, financial power, visual culture, and professional codes: that is, all economical, cultural and political conditions of development and access which determine what and in which manner an image will be represented to society.

Full textI den här uppsatsen undersöks en gård i Ljusdalsbygden i Hälsingland som kallas Utigården. På gården finns idag en byggnad som kallas mangelstugan där måleri och tapeter från 1806-1807 finns bevarat. Frågeställningen är när, hur och varför den inreddes samt vem eller vilka som kan ha utfört arbetet. Syftet är att frångå generella förklaringar, lägga ett mer individuellt perspektiv på en interiör och på så vis ge den ett mervärde. Arkivariska källor och litteratur tolkas tillsammans med den fysiska byggnadens interiör för att i viss mån kartlägga den sociala och ekonomiska kontexten som omgav interiören. Mangelstugan interiör visar också prov på hur måleri och tapeter verkade sida vid sida. Ur deras estetiska uttryck samt rumsplacering tolkas statusskillnader mellan de båda samt att mangelstugan bör ha varit en representativ byggnad. Stilinfluenser belyses också. Bland annat lyfter uppsatsen fram en fransk tapet som högst sannolikt varit förlaga till mellankammarens måleri i mangelstugan. Här säkerställs att allmogemålarna använde sig av förlagor, men att slutresultatet var unikt och personligt. Mangelstugans interiör visar prov på hur en sådan interiör kunde se ut på början av 1800-talet i en gård i ljusdal och ett möjligt scenario rörande upphovsmännen, där Ljusdalsmålarna Arve och HindriksOlle lyfts fram som potentiella upphovsmän, bidrar till att knyta fler värden till interiören vilket förhoppningsvis leder till ökade möjligheter att bevaras. I uppsatsen klargörs att gården bör ha flyttats till dagens gårdsläge troligen mellan 1802-1806 samt att mangelstugan uppförts efter flytten och av dateringarna att döma år 1806. Olof Jonsson brukade hemmanet när mangelstugan byggdes och inreddes. Hans bouppteckning visar att gården bör ha varit välställd. Utifrån detta diskuteras hur mangelstugan fyllde många funktioner. Representativitet, manifestation, exkluderande och inkluderande samt estetiska kvalitéer är exempel på sådana.
The focus of this essay is a building belonging to a farmhouse in Ljusdal, Hälsingland, called Utigården. The building has wallpaper and mural paintings preserved from the beginning of the 19th century. The aim of this essay is to investigate when, how and why the interior was made as well as by whom. This serves to put a more individual perspective on one certain interior instead of using more general explanations. This knowledge will lead to more knowledge and values being ascribed to this interior and hopefully an increased will to preserve it in the future. It gives us an example of how an interior from this time might look like, how traditional paintings are mixed with modern motives and wallpapers and how all of this together is symbolic and guides us through the rooms. Their aesthetic qualities shows that it was most probably a representative building. Different theories about influnces and inspiration are also illustrated. The mapping of certain social and economical factors serves to show the circumstances for when the interior was made as well as why. Probably the farm was moved between 1802-1806 and this might explain the new building. Different theories of why it was important to invest in these representative building and what different values they might have fulfilled are also discussed in this essay. Representatation, including and excluding factors and aesthetic values are some of them. Two potential painters are discussed as having painted the interior. They are called Arve and HindriksOlle. A possible scenario is created around their connections to Utigården.

Full textOur thesis offers to analyze the transformation of wage earner relations through a cross reading of the productive models dynamics and the growth of the service relation. We venture the hypothesis that the relationship with the customer becomes a source of profit achieved by paid work at different level, which leads to a transformation of productive models characterized by a stronger division in work and employment. The analysis of this hypothesis is made for the specific case of call centers on the basis of a purely practical analysis carried through sectorial interviews and eight case studies. With regard to abundant sources about this study, our research offers to adopt an original angle of analysis consisting in taking into account call centers regarding their base within productive organization. We start by assuming that call centers activity isn’t entirely new and that it ensues from a transformation of former situation. Thus we have to study the activity with regard to its integration within a work division process. The implementation of the frame of reference of a productive model allows us to underline in this context a reconstruction and a division of the various dimensions of service relation through the whole industry. It leads to a flexible segmentation of jobs and a common rationalization of works borrowing an industrial and professional reasoning but which highly uses employees subjective commitment

Full textUsing a mode of organization alternative to the market, armaments production allows the firms to obtain a rent through an information asymmetry (bilateral monopolies). However this aspect is not essential to understand the specificity of that production. What makes the difference is the importance that the armed forces give to technological performances of armaments. This "technophile bias" arises from the necessity to get or maintain a technological superiority; it engenders a research program permitting to organize armaments as a system and develop innovating research fields. Operating within this mechanism, the armaments production represents more than a mesosystem. The conjugation of industrial, political, financial, budgetary, and also strategic and technological variables gives birth to a "hypersystem" which functioning is ruled by an organizing principle called "syzygy", i. E. A set of relations stemming from a technological fund common to several mesosystems. This original configuration explains the peculiar place of armament in the dynamics of the productive system. The syzygy engenders a scientific and technique potential which overshoots its military objectives and could result in commercial applications. Nevertheless the commercial valorisation of these new technologies calls a voluntary behaviour from the firms. The economic growth or depression explain that the connection between armaments production and commercial activities varies in accordance with the evolution of economic activities and investment opportunities. The armaments firms play an important role in that transfer process, as well as the commercial ones-especially thanks to the creation of interfaces by public centres of military research & development

Full textSome photoautotrophic cyanobacteria species are able to fix dinitrogen thanks to specialized cells, the heterocyts. Moreover, these cells are known to secrete ammonia when the glutamine synthase activity is partially inhibited under aerobic conditions. They are considered as potential cell factories for fertilizer. The present study uses a mutant strain of Anabaena variabilis PCC 7937-C9, a fast-growing heterocytous cyanobacterium, to investigate the potential use of diazotrophic cyanobacteria in photobioreactors for ammonium production. The growth characteristics of this strain cultivated in chemostat cultures are not significantly different from those of the wild strain, with a maximal specific growth rate of 3.0 d–1 at 30°C. A part of the combined nitrogen excreted in the culture medium is shown to be stripped through the aeration of the cultures as NH3, indicating previous underestimation of NH4 +/NH3 excretion. This process is shown to be affected by parameters such as temperature, irradiance, gas flow rate and MSX concentrations. Kinetics study reveals that the dissolved NH4 +/NH3 as well as the gaseous NH3 productions are correlated to pH variations production; a pulse regulation of pH is used to increase the NH3 production. Chemostat cultures with pH regulation are used to confirm that maximal gaseous NH3 is produced at pH 8.8. A cyclic variation of dissolved NH4 +/NH3 seems to regulate the NH4 +/NH3 concentrations under a threshold level of 1.5 mmol L–1; uptake of NH4 + by vegetative cells seems to be involved. These physiological features are discussed in view of operative conditions for efficient nitrogen supply for production by oleaginous microalgae

Full textI ljuset av världens miljöproblem måste varje samhällsinstans, och i sin tur våra industrier, ta sitt ansvar för att nå de mål som ställts för att säkerställa en hållbar framtid. Stålindustrin står globalt för nästan 10% av alla koldioxidutsläpp och är en stor aktör i detta problem. Det är viktigt att förändra dess processer om vi ska nå våra uppsatta mål. Den svenska stål- och energiindustrin har börjat samarbeta för att lösa detta och förbli konkurrenskraftig på en framtida marknad som värderar hållbarhet högre än någonsin. Detta är bakgrunden till HYBRIT-projektet som arbetar på ett nytt sätt att producera stål med hjälp av väte istället för kol, i en process som kallas hydrering. Vätgas kan produceras på många sätt, men elektrolys påvisar en god hållbara potentialen och är därför i fokus för HYBRIT. Fokus för detta projekt är att undersöka den ekonomiska potentialen för väteproduktion genom elektrolys i samband med havsbaserad vindkraft. Olika systemstorlekar, typer och designer utvärderades för att förstå hur och om detta kan anses ekonomiskt genomförbart. Under studien blev det klart att dessa typer av projekt påvisar stor potential för att minska koldioxidutsläppen och en ekonomisk potential kunde observeras. Bekymmer uppstår när man försöker nå de lägsta vätgaspriserna på marknaden idag, men även vid dessa kan systemet värderas positiva när man tillämpar låga interna avkastningsräntor. De viktigaste slutsatserna är att det finns en ekonomisk potential för ett elektrolyssystem i förhållande till havsbaserad vindkraft. Vilket värde systemet tar, beror framförallt på investeringskostnader, el priser och avtal mellan berörda parter. Grön vätgas skulle dessutom kunna värderas högre än industrins lägsta pris och därmed öka värdet ytterligare. Man kan också dra slutsatsen att tillgängligheten av kraftproduktion och vätgasförvaring kraftigt påverkar mängden grön energi som utnyttjas i processen.

Full textThe subject of this thesis consists of an analysis of the relationship between electricity consumption and Gross Domestic Product from the perspective of Competitive Intelligence. More specifically, it analyzes the evolution of the electrical intensity of economic activity from 2003 to 2012 in the developed countries of the G7, and then estimates their electricity needs from 2013 to 2022. Part one attempt to explore theoretical and practical aspects of Competitive Intelligence to understand and apply them, while part two is devoted to the empirical analysis itself.Concerning the latter, our results are as follows:First, the electrical intensity curves of two countries—Canada and the United States—dominate those of other developed countries; thus, the economies of these two North American countries are more energy-hungry than those of Japan and the countries of the European Union. The overall temporal evolution of electricity consumption per GDP unit over a ten-year period (2003-1012) has gone down in five countries: Canada (-12%), the United Kingdom (-5.3%), the United States (-5%), France (-4%), and Germany (-3%). On the other hand, this evolution has gone the other direction in Japan (+5%) and Italy (+6%). The effect of “structure” is negative across all analyzed data, suggesting general “tertiarisation”. However, the effect of “electricity efficiency” is mixed: it is negative in the United States and Canada, but positive for the rest of group.Second, estimations indicate an overall growth in electricity demand across all G7 countries from 2013 to 2022. Additionally, electrical elasticity coefficients/GDP units are down in all countries except Italy. This tells us that the average annual demand for electricity in these countries should increase at a slower rate than their respective GDPs.Lastly, the primary research perspectives that appear at the beginning of this thesis concern the transposition of our model of analysis (energetic intelligence) onto other forms of energy such as oil, natural gas, coal, and renewable energy sources. In the end, this model could be useful to economic and political authorities (governments, private companies, NGOs, IGOs, etc.) as an instrument of economic, energy, and environmental policy

Full textIdag används biogas till stor del som drivmedel för bussar inom kollektivtrafik i Sverige. Denna studie undersöker möjligheter och hinder för en fortsatt nationell användning och produktion av biogas, i samband med att bussar inom kollektivtrafiken nu elektrifieras. Analysen är baserad på intervjuer med aktörer inom kollektivtrafiken och biogassektorn, sakkunniga inom biogas, och alternativa användare av biogas. Tre regioner, Stockholm, Västra Götaland och Skåne, valdes som fallstudier för analys av möjligheter för fortsatt användning inom kollektivtrafiken. Alternativa användningar studerades istället ur ett nationellt perspektiv, och inkluderade vägtransporter, sjöfart, industri och el- och värmeproduktion. Studien visar att det råder enighet mellan intervjupersoner att förnybara resurser över lag ska användas där de medför störst samhällsnytta sett till samhället i stort. Inom kollektivtrafiken beskrivs elbussar därför som fördelaktiga i stadsmiljöer, medan biogas ses som lämpligt i regional trafik. Biogas framställs dessutom som miljömässigt fördelaktigt i alla alternativa användningsområden utom kontinuerlig el- och värmeproduktion, eftersom då främst förnybara och inte fossila resurser ersätts. Med hänsyn till kostnader och konkurrenskraft ses lätta och tunga transporter tillsammans med kundnära industrier, t.ex. livsmedelsindustrin, som troliga framtida användningsområden för biogas. Ekonomiskt stöd från styrmedel bedöms vara nödvändigt för en fortsatt utveckling av biogassektorn i Sverige, även om dagens styrmedel, t.ex. skattebefrielsen, beskrivs som kortsiktiga och oförutsägbara. Betalningsviljan för biogasens samlade samhällsnyttor minskar också vid en övergång från offentliga till privata kunder. Eftersom biogas därtill har en begränsad eller osäker konkurrenskraft jämtemot andra alternativ i de privata segmenten, identifierar denna studie risker för stagnation eller nedgång i användning och produktion av biogas vid en eventuell utfasning från den offentliga sektorn, givet dagens situation.

Full textThe objective of this study is to analyse the law relating to exploration and production of oil and gas in Tanzania in relation to the protection of FDI. The analysis will be based on the international standards for the protection of FDI. Some of these standards are contained in international instruments and some of them have attained the status of customary international law. Examples of such standards include: Fair and Equitable Treatment (FET), Full Protection and Security (FPS), non-arbitrariness and non-discrimination, among others. Some international instruments to be referred to include the 1992 World Bank Guidelines on Treatment of FDI and the CERDS.

Full textThis thesis demonstrates that, throughout history, before the Spanish conquestuntil the 21st Century, agriculture has been an important activity of the mapuchepeople. Research conducted points out the ability of the mapuche to resist andbattle against powerful and ferocious foes, and in addition, their intelligentadaptation to foreign invasions, including that of the State of Chile. The thesisdemonstrates the changes that took place in agriculture and the ability of themapuche people to innovate, since the Inca invasion in the 15th century, theSpanish conquest through the 16 to 19th centuries, and the Chilean occupationthat extends reaching the 21st century. At the start of the Spanish conquest,mapuches constituted people that autonomously occupied a territory, were fullysedentary, communities populated clearly delimited areas, and conductedagriculture of cultural subsistence, in addition to harvesting native vegetation,fishing and hunting. Society was matricially organized by lineages, by groups,had a cosmic view, culture and social organization. During the Colony, theyadopt and appropriate European technology, develop a powerful animalhusbandry that extends through the Argentinian pampa; this activity generates astrong and diversified commercial exchange between the mapuche territory andthe Kingdom of Chile, of animal products, handicrafts and food products.Exchange was unfavorable for the mapuche and had to be regulated throughparliaments. The Chilean Republic at first recognized the mapuche territories,but later, for reasons of economic expansion, occupies them through war.Mapuches resist and are defeated by the Chilean army that had recently wonthe Pacific Ocean War against Peru and Bolivia. The mapuche enter the 20thcentury deprived of 95% of their territory, almost the total of their powerfulanimal husbandry, their capital goods, machinery, equipment, annual andperennial crops. But above all, they are excluded, segregated, faced withassimilation and extermination strategies, they die from hunger, diseases andpests. The real historical debt of the State of Chile with the mapuche generatesat that point. Agrarian reforms, in particular that of the Popular Unity (1970-73)political government faces the problem of usurped lands and initiates solutions,later reversed by the Military Government (1973-90). Concertation forDemocracy governments (1990-2010), recognizes the specificities of themapuche people and partially solves land conflicts. At present, rural mapucheface powerful strategies of assimilation and cultural extermination; however, atthe rural communities’ level, the ability of the mapuche people to adapt tochanges, adequate, resist, and impose the basic terms of the conditionsnecessary to reconstruct themselves as a Chilean original people has becomeclearly evident
Esta tesis demuestra la existencia de la agricultura como actividad importantedel pueblo mapuche a través de la historia antes de la conquista hasta el sigloXXI. La investigación demuestra la capacidad de los mapuches para resistir ycombatir a enemigos poderosos y feroces y además la inteligente adaptación atodas las irrupciones extranjeras incluidas las del Estado de Chile. La tesismuestra los cambios en la agricultura y la capacidad del pueblo mapuche parainnovar, desde la invasión de los incas en el siglo XV, la conquista de losespañoles entre los siglos XVI y XIX y la ocupación chilena hasta llegar alsiglo XXI. Los mapuches al momento de la conquista española eran un puebloque ocupaba un territorio en forma autónoma en plena sedentarización, lascomunidades poblaban terrenos delimitados y desarrollaban agricultura desubsistencia cultural, además de la recolección, la pesca y la caza. La sociedadestaba organizada por linajes matricialmente, por grupos, tenían unacosmovisión, una cultura y una organización social. Durante la colonia, adoptany se apropian de tecnologías europeas, desarrollan una poderosa ganaderíaque se extiende por la pampa Argentina; esta actividad genera un fuerte ydiversificado intercambio comercial entre el territorio mapuche y el Reino deChile, de productos animales, artesanado y productos alimentarios. Elintercambio era desfavorable a los mapuches y debió ser regulado medianteparlamentos. La República comienza reconociendo los territorios mapuche,pero luego, por razones de expansión económica los ocupa a sangre y fuego.Los mapuche resisten y son derrotados por el ejército Chileno que ganó laguerra del Pacifico. Los mapuches entran al siglo XX despojados del 95% desus tierras de casi toda su poderosa ganadería, de sus bienes de capital,maquinas, equipos, arreos, siembras y plantaciones. Pero sobre todo sonexcluidos, segregados enfrentados a estrategias de asimilación y exterminio,mueren de inanición, por enfermedades y por la peste. Allí se genera laverdadera deuda histórica del Estado de Chile con los mapuches. LasReformas Agrarias, especialmente la de la Unidad Popular, levantan elproblema de tierras usurpadas y propones y ejecuta soluciones, que ladictadura militar anula. La Concertación por la Democracia reconoce lasespecificidades del pueblo mapuche y soluciona una parte de los conflictos porla tierra. Actualmente los mapuche del campo enfrentan poderosas estrategiasde asimilación y exterminio de su cultura, sin embargo a nivel de lacomunidades rurales se pone de manifiesto la capacidad del pueblo mapuchepara adaptarse a los cambios, adecuarse, resistir e ir imponiendo los términosbásicos de las condiciones necesarias para reconstruirse como pueblooriginario de Chile
