Full textBakgrund: Företag är beroende av en mängd olika intressenter som alla har ett behov av att de tillgångar som redovisas är korrekt värderade Detta gäller inte minst fastighetsbolag vars tillgångsmassa till största del består av fastigheter vilka ligger till grund för värderingen av bolaget. RR 17 innebär att företagen inför varje rapporttillfälle måste göra en bedömning av sina tillgångar och när det redovisade värdet överstiger återvinningsvärdet ska det skrivas ned. Rekommendationen är mycket omfattande och innehåller bland annat riktlinjer för hur beräkning av återvinningsvärdet ska ske.
Syfte: Syftet med uppsatsen är att utifrån ett redovisningsperspektiv genomföra en kritisk granskning av RR 17.
Tillvägagångssätt: Här redogör vi för varför vi valt fastigheter. Vi beskriver hur vi har sökt information, gjort urval bland bolag och personer samt hur vi har lagt upp och genomfört våra intervjuer. Vi avslutar kapitlet med kritik mot det sätt vi valt att utföra granskningen på.
Resultat: Vi anser att det är bra när ett värde har hög relevans men att det inte får ökas på bekostnad av lägre objektivitet. Vår egen åsikt som externa bedömare är att tillförlitligheten inte har ökat. Införandet av RR 17 har inte medfört att bolagen har fått ökade kostnader. Vi tycker att det råder brist på precision i underlaget för nedskrivning.

The assignment is to compare two different PLC development tools and determine how a transition toa new PLC development tool would be. The programs that will be compared is the current toolAutoCAD with the extension ACG and CoDeSys.
A transition from AutoCAD to CoDeSys is realizable but will take considerable time and effort. Theeasiest way to achieve this is to during the transition generate an export file from the existing drawingsin AutoCAD which then can be imported to CoDeSys. By this CoDeSys can be used as a platform fordeveloping. This is fully realizable because ACG which generates the C code can be modified togenerate almost any export file.

The actually dissertation has as object the negotiations identity of peruvians who migrated to the city of Boa Vista between the years 1990 to 2010. To investigate this phenomenon started from the hypothesis that relations of friendship and kinship influence the migratory process of peruvians and impact negotiations identity experienced by them. In this sense, one of the concerns of this work is understand the motivations and meanings of different personal trajectories of men and women of peruvian nationality who left their country of origin and they integrated in another sociocultural reality. So, to verify the proximity between brazilians and peruvians and the different levels of changes made between them, to reveal the identity aspects that determine and characterize the insertion of peruvian migrants in Boa Vista´s society, was used the qualitative methodology, with an emphasis in the open interviews and informal conversation. The interlocutors of the study were men and women of peruvian nationality, between 18 and 72 years old, who came at different periods and they exert different professional activities, as merchants, doctors and teachers. The light of the theories of migration studies and identity was possible to understand how the peruvian migrants negotiate their identities, according to their migration experiences, although they are away from their place of origin, they do not lose the native culture and identity like a reference. However, they also incorporate elements of culture, and the identity of the destination enabling the negotiation of their identities through their survival strategies, from their representations, the dilemmas of their own migrant status and through of mediation wherein feel understood by Boa Vista´s society. In this context, the families networks and friendships of peruvian migrants, they strengthen the referential significant of place of origin, well as the condition of migrant subject.
A presente dissertação tem como objeto as negociações identitárias dos peruanos que migraram para a cidade de Boa Vista entre os anos de 1990 a 2010. Para investigar esse fenômeno partiu-se da hipótese de que as relações de amizades e de parentesco influenciam o processo migratório de peruanos e impactam as negociações identitárias vivenciadas por eles. Neste sentido, uma das preocupações deste trabalho é entender as motivações e os diferentes significados das trajetórias pessoais de homens e mulheres de nacionalidade peruana que deixaram seu país de origem e se integraram em outra realidade sociocultural. Desta forma, para verificar a proximidade entre brasileiros e peruanos e os diferentes níveis de trocas realizadas entre eles, de modo a revelar os aspectos identitários que condicionam e caracterizam a inserção dos migrantes peruanos na sociedade boa-vistense, utilizou-se a metodologia qualitativa, com ênfase nas entrevistas abertas e conversas informais. Os interlocutores da pesquisa foram homens e mulheres de nacionalidade peruana, entre 18 e 72 anos, que se deslocaram em períodos diversos e que exercem distintas atividades profissionais, como comerciantes, médicos e professores. A luz das teorias dos estudos migratórios e identitários foi possível compreender como os migrantes peruanos negociam suas identidades, segundo suas experiências migratórias. Embora estes estejam afastados de seu local de origem, não perderam a cultura e a identidade nativa como referência. Contudo, eles também incorporam os elementos da cultura e da identidade do local de destino, possibilitando a negociação de suas identidades por meio de suas estratégias de sobrevivência, de suas representações, dos dilemas próprios à sua condição de migrante e por meio de uma mediação em que se sintam compreendidos pela sociedade boa-vistense. Nesse contexto, as redes familiares e de amizades dos migrantes peruanos fortalecem os referenciais significativos do lugar de origem, bem como a condição de sujeito migrante.

The objective of this dissertation was to investigate the genesis and evolution of the lateritic lithotypes, resulting from the weathering in savannah areas in the region of Tucano ridge. The structural and textual characteristics were studied and the mineralogy, the chemical composition of the chemical elements Al, Ca, Si, Fe, K, Mg, Na, P, Ti, PF, trace elements (As, Au, B, Ba, Be, Bi, Cd, Co, Cr, Cu, Cs, Ga, Ge, Hf, Hg, Li, Mn, Mo, Nb, Ni, Pb, Pd, Rb, Re, Sb, S, Se,Sc, Sn, Sr, Ta, Te, Th, Tl, U, V, W, Y, Zn, Zr and ETR) and Pb isotopes was analyzed. In the region there are from thin, thick sandstones to rusty conglomeratic (Fe oxidation), vermiform crusts, protopisolitic, pisolitic, loosed concretionary material and clay and sandy soils consisting primarily of quartz, goethite-hematite, kaolinite, anatase, rutile and gibbsite. In the southwestern (SW) of Tucano ridge there is Redondo Hill constituted of diabase. The Si is high in the diabase, in the sandstones and in the soils while Fe is higher in the crusts and in the concretionary whereas Al and Ti are high in the soils. The alkalis and P are below the limit of the lateritic lithotypes detection and they are higher in the diabase. The Ba, Co, Cr, Cu, Ni, Rb, Sc, Sr, W and Zn are more concentrated in the diabase. The Ag, As, Au, Bi, Ga, Hg, Sb, Se, Sn, Pb, Tl, Th and V are in the crusts and concretionary. The Hf, Nb and Zr are in the soils and the Mn in the conglomeratic and thick sandstones, in the pisolitic crust, in the concretionary and in the clay soils. The REE are more concentrated in the conglomeratic sandstone, in the pisolitic crust, in the concretionary 2 and in the soils where there are positive anomalies of Ce/Ce* and soft and negative ones of Eu. In the isotopic studies, higher rations of 207Pb/206Pb in the sandstones conglomeratic and clay soils and the rations of 208Pb/206Pb are higher especially in the diabase, in the thick sandstones to rusty conglomeratic, in the concretionary and in the clay soils. No estudo isotópico as razões do 207Pb/206Pb são elevadas no arenito conglomerático e solos argilosos e as razões do 208Pb/206Pb são mais altas no diabásio, arenitos conglomerático e grosso, no concrecionário e nos solo argiloso. The geochemistry allowed three associations that define the lithotypes signatures: 1) Fe and PF representing the crusts; 2) P, Ba, Co, Mn, V and Zn represent the diabase; and the 3) Al, Si, Ti, Cs, Hf, Nb, Ta, Y, Zr and REE represent the soils. The lateritic crusts found in the region of Tucano ridge possibly had their development after the Miocene, with the individualization of the vermiform facies, protopisolitic and pisolitic towards the quaternary in similar conditions to the present climate.
Esta dissertação teve como objetivo investigar a gênese e a evolução dos litotipos lateríticos resultante do intemperismo em áreas de savana na região da Serra do Tucano. Foram estudadas as características estruturais, texturais e analisados a mineralogia, a composição química do Al, Ca, Si, Fe, K, Mg, Na, P, Ti, PF, elementos traços (As, Au, B, Ba, Be, Bi, Cd,Co, Cr, Cu, Cs, Ga, Ge, Hf, Hg, Li, Mn, Mo, Nb, Ni, Pb, Pd, Rb, Re, Sb, S, Se, Sc, Sn, Sr, Ta, Te, Th, Tl, U, V, W, Y, Zn, Zr e ETR) e isótopos de Pb. Na região ocorrem arenitos finos, grossos a conglomeráticos ferruginisados agrupados na Formação Serra do Tucano e diabásio do Complexo Vulcânico Apoteri, crostas vermiformes, protopisolíticas, pisolíticas, material concrecionário solto e solos argilosos e arenosos, constituídos basicamente de quartzo, goethita+hematita, caulinita, anatásio/rutilo e gibbsita. A Si é elevada no diabásio, nos arenitos e solos, enquanto o Fe é mais alto nas crostas e no concrecionário, enquanto o Al e Ti os são nos solos. Os álcalis e P estão abaixo do limite de detecção nos litotipos lateríticos. O Ba, Co Cr, Cu, Ni, Rb, Sc, Sr, W, Zn estão mais concentrados no diabásio, Ag, As, Au, Bi, Ga, Hg, Sb, Se, Sn, Pb, Tl e Th, V nas crostas e concrecionário, Hf, Nb e Zr nos solos e o Mn nos arenitos conglomerático e grosso, na crosta pisolítica, no concrecionário e nos solos argilosos. Os ETR estão mais concentrados no arenito conglomerático, na crosta pisolítica, no concrecionário 2 e nos solos, onde há ocorrência de anomalias positivas de Ce/Ce* e suaves e negativas de Eu. No estudo isotópico as razões do 207Pb/206Pb são elevadas no arenito conglomerático e solos argilosos e as razões do 208Pb/206Pb são mais altas no diabásio, arenitos conglomerático e grosso, no concrecionário e nos solo argiloso. A geoquímica permitiu diferenciar três associações que definem a assinatura dos litotipos: 1) Fe e PF representando as crostas; 2) P, Ba, Co, Mn, V e Zn representam o diabásio, e a 3) Al, Si, Ti Cs, Hf, Nb, Ta, Y Zr e ETR representando os solos. As crostas lateríticas encontradas na região da Serra do Tucano possivelmente tiveram seu desenvolvimento após o Mioceno, com individualização dos fácies vermiforme, protopisolítico e pisolítico ao longo do Quaternário, em condições similares ao clima atual.

Full textOs minerais estão presentes no cotidiano humano sob as mais variadas formas, seja no campo da metalurgia, da indústria química, da construção civil ou do cultivo da terra. De uma maneira geral, constata-se que o caminho trilhado pelo desenvolvimento da humanidade foi e é alcançado mediante a busca e utilização de bens minerais. Dada a extensão territorial e a diversidade geológica encontrada no solo e subsolo, o Brasil apresenta como detentor de importante potencial minerário no cenário mundial. Nesse contexto, Roraima constitui-se numa região que foi tradicionalmente voltada à exploração de bens minerais, sobretudo ouro e diamante. Principal porto fluvial do estado de Roraima, muito importante em passado recente, o município de Caracaraí RR perdeu sua função axial com a construção da rodovia BR-174. O desenvolvimento de sua zona rural está baseado na pecuária, o núcleo urbano no comércio e serviços e o setor minerário ainda incipiente. Este estudo enfoca um levantamento dos recursos minerais de importância econômica, inclusive os que estão em fase de exploração no município, utilizando como meios auxiliares produtos de sensoriamento remoto e dados de campo. Foram pesquisados 19 pontos amostrais, sendo oito nas proximidades da BR-174 e 11 em bibliografias consultadas. Foram confeccionadas cartas imagens de ocorrências minerais, substâncias minerais e de mineração em atividade. Caracaraí possui áreas de potencial mineral, tais como areia, seixo, argila, granito e laterita, com ocorrências de ouro. Outros minerais têm sido descobertos na forma de pequenos depósitos ainda pouco investigados, porém as áreas destinadas às terras indígenas e conservação ambiental, conduzem à redução da exploração dos mesmos, além de criar barreiras impedindo os avanços no conhecimento geológico e nas descobertas de novas ocorrências minerais no município.
The minerals are present in everyday human under the most varied forms, whether in the field of metallurgy, chemical industry, construction or farming. In general, it appears that the path followed by the development of humanity was and is achieved by seeking and use of mineral commodities. Given the territorial extension and geological diversity found in soil and subsoil, Brazil has great potential as a holder of mining on the world stage. In this context, Roraima is in a region that has traditionally focused on the exploitation of minerals, especially gold and diamonds. Main river port in the state of Roraima, very important in the recent past, the city of Caracaraí - RR lost its axial with the construction of highway BR-174. The development of their rural area is based on farming, the urban core in trade and services and the mining industry still in its infancy. This study focuses on a survey of economically important mineral resources, including those in the exploration stage in the city, using as auxiliary products of remote sensing and field data. We surveyed 19 sampling points, eight near the BR-174 and 11 in bibliography. Images were prepared letters of mineral occurrences, mineral and mining activity. Caracaraí has areas of mineral potential, such as sand, gravel, clay, granite and laterite, with gold occurrences. Other minerals have been discovered in the form of small deposits still poorly investigated, but the areas allocated to indigenous lands and conservation, leading to reduce the exploitation of them and create barriers impeding progress in geological knowledge and discoveries of new mineral occurrences in the city.

The lateritic crusts, which represent the relict of paleoclimatic changes especially between the Cenozoic and the Recent, allow inferring the conditions and the evolution of weathering in the intertropical region of the Earth. At the edge of the Guianas Shield, in the central region of Roraima, where occur lateritic crusts outcropping, has developed the Graben of the Tacutu. It`s reactivation in the Pliocene caused severe erosion what the region tectonically unstable. With the objective to determine the implications of that environment in the weathering of the basement rocks from the Guiana Shield, the region of Mucajai was selected to where it is situated the Serra da Prata and to a less extent the Serra da Moça. These relief features are inserted in the Piedmont Rio Branco-Rio Negro, and its surroundings lowered portion on the Dissected Plateau North of the Amazonas. Rocks, crusts and soils of the region were studied on basis of field survey of the lithotypes and their textural, mineralogical and geochemical characterization. The major oxides, the trace elements (Mn, Zr, V, Ni, Cu, Zn, Sc, Co, Ga, Cr, Y, Th, Hf, Nb, Ta, Ba, Mo, Sr, Rb, Cs, U, W, As, Au, Ag, Hg, Ge, In, Li, Sb, Se, Te, Tl and ETR) and the Pb isotopes were analyzed. The lateritic lithotypes developed from charnockites, gabbro, granites and gneisses. Crusts of protopisoliticas and pisoliticas types were formed at the top of the Serra da Prata and vermiform in the lower portions of the landscape which are cover by clay-sandy reddish brown soils. The crusts are immature, friables with abundant clay matrix, composed mainly of goethite and hematite, and low content of gibbsite. The rocks are distinguished by SiO2, Na2O, K2O, Ba, Rb, Tl, Y, Mo, REE (La-and Eu) association, while the lateritic rocks by Fe2O3, PF, Co, Cr, Ga, Zn, Mn, W . There is a greater geochemical affinity between the crusts and soils with granite, charnockite and gneiss than with the gabbro, as they are the most abundant rocks and also because they have little chemical variation; however, the Pb isotopic ratios indicate provenance from the charnockite. The development of these crusts marks the Quaternary landscape evolution of the central portion of Roraima after the tectonic reactivation in the Miocene.
As crostas lateríticas, que representam os relictos das transformações paleoclimáticas especialmente entre o Cenozóico e o Recente, permitem inferir as condições e a evolução do intemperismo na região intertropical da Terra. Na borda do Cráton das Guianas, região central de Roraima, se desenvolveu o Grabén do Tacutu, onde afloram crostas lateríticas. Essa área cratônica foi reativada no Plioceno o que propiciou intensa erosão ao tornar a região tectonicamente instável. Com o objetivo de determinar as implicações desse ambiente no intemperismo das rochas do embasamento do Cráton das Guianas, foi selecionada a região de Mucajaí onde ocorrem a Serra da Prata e com menor expressão a Serra da Moça. Essas feições de relevo fazem parte do Pediplano Rio Branco-Rio Negro, e seu entorno rebaixado, do Planalto Dissecado Norte da Amazônia. Foram estudadas as rochas, as crostas e os solos da região com base em levantamento de campo dos litotipos e na caracterização dos aspectos texturais, mineralógicos e geoquímicos. Foram analisados os óxidos maiores e menores (SiO2, Fe2O3, Al2O3, K2O, Na2O, CaO, MgO,TiO2, P2O5, PF) os elementos traços (Mn, Zr, V, Ni, Cu, Zn, Sc, Co, Ga, Cr, Y, Th, Hf, Nb, Ta, Ba, Mo, Sr, Rb, Cs, U, W, As, Au, Ag, Hg, Ge, In, Li, Sb, Se, Te, Tl e ETR) e isótopos de Pb. As crostas lateríticas desenvolveram-se a partir de charnockítos, gabros, granitos e gnaisses. São do tipo protopisolíticas a pisolíticas no topo da Serra da Prata e vermiformes nas porções rebaixadas, ambas recobertas por solos argiloarenosos marrom avermelhados. As crostas lateríticas são friáveis com abundante matriz argilosa, com predominância de goethita sobre hematita, e baixo conteúdo de gibbsita, portanto são pouco evoluídas, destacando-se apenas por seus conteúdos de Fe2O3, PF, Co, Cr, Ga, Zn, Mn e W, enquanto as rochas se diferenciam pela associação SiO2, Na2O, K2O, Ba, Rb, Tl, Y, Mo, ETR (-La e Eu). Apesar das razões isotópicas de Pb indicarem que as crostas lateríticas tiveram proveniência a partir do charnoquito, os dados geoquímicos mostraram maior afinidade entre essas e as rochas mais abundantes (granito, charnoquito e gnaisse), devido suas similaridades químicas. O desenvolvimento destas crostas marca a evolução quaternária da paisagem após a reativação tectônica da região no Mioceno.

O presente trabalho sobre o fenômeno ecoturismo no Lago Caracaranã, localizado no estado de Roraima, caracteriza-se como uma pesquisa pioneira na área de estudo e que reflete o contexto de crescente produção científica sobre turismo sustentável, ecoturismo e etnoturismo no Brasil e no mundo. O trabalho tem como objetivo analisar a evolução do ciclo de vida dos serviços de ecoturismo no Lago Caracaranã, no período entre as décadas de 1970 e 2010, sendo elaborada com base em uma lógica dedutiva que se fundamentou nos procedimentos metodológicos de revisão bibliográfica e documental e estudo de caso. Os resultados da pesquisa demonstram que há um ciclo de vida na exploração do turismo no Lago Caracaranã inflexionado pela demarcação da Terra Indígena Raposa Serra do Sol (TIRSS) pelo Supremo Tribunal Federal (STF). Conclui-se na pesquisa que o território do Lago Caracaranã apresenta uma dinâmica formação territorial na curta duração, permeada pela mudança nos direitos de propriedade da terra em razão da demarcação da TIRSS, o que repercutiu em negativas inflexões abruptas no ciclo de vida do ecoturismo.
This work about the ecotourism phenomenon in the Caracaranã Lake located in the state of Roraima is characterized as a pioneer research in the study area and also reflects the context of growing scientific production on sustainable tourism, ecotourism and etnotourism in Brazil and worldwide. This dissertation aims to analyze the evolution of the life cycle of ecotourism services in the Caracaranã Lake from the 1970s up to the 2010s. It has been prepared on a deductive logic based on the methodological procedures of bibliographic and documentary review and case study. The results of this research demonstrate the existence of a lifecycle in the exploration of the tourism in the Caracaranã Lake that has passed by an inflection since the demarcation of the Raposa Serra do Sol Indigenous Land (TIRSS) due to the final decision of the Federal Supreme Court (STF). Conclusions of this research in the area of the Caracaranã Lake have pointed out a dynamic territorial formation in short run permeated by the change in ownership rights of the land since the demarcation of the TIRSS that reflected negative sharp inflections in the ecotourism lifecycle.

Full textO presente estudo procurou analisar o discurso dos professores de língua portuguesa do município de Bonfim, na divisa entre o Brasil e a Guiana, para verificar como esses profissionais lidam com o bilinguismo de seus alunos em suas práticas docentes. Esta pesquisa qualitativa de cunho etnográfico procurou entender como numa região onde há prevalência de grande diversidade linguística e cultural perpassam as questões referentes a pluralidade linguística ali existente, e saber como está arraigado nas práticas discursivas dos professores a ideia de hegemonia cultural, currículo monocultural e monolinguístico. Para responder essa problemática, empregou-se, como aporte teórico e metodológico, a Análise do Discurso, por ser a construção de um outro olhar sobre as práticas linguageiras e o redimensionamento do objeto de análise: o discurso de professores. Procurou-se compreender os processos discursivos sobre as práticas educacionais desses docentes buscando analisar sua formação discursiva, social e ideológica dentro de um contexto de fronteira. Esses profissionais atuam em uma realidade bilíngue na qual a maioria de seus alunos são oriundos de Lethem ou de comunidades indígenas, sendo estes falantes do inglês ou de uma língua indígena Wapixana e/ou Macuxi, além do português. Como resultado deste estudo, verificou-se que nesse ambiente, o professor se diz não preparado para lidar com tal realidade, pois não há programas educacionais no município que valorizem essa diversidade linguística e tampouco ele se diz preparado para atuar nesse contexto em decorrência das instituições superiores não lhe prepararem adequadamente para lidar com tal situação.
The present study sought to analyze the speech teachers of Portuguese language of the municipality of Bonfim, on the border between Brazil, Guyana to check how these professionals deal with the bilingualism of your students in their teaching practices. This qualitative ethnographic research sought to understand how nature in a region where there is high prevalence of linguistic and cultural diversity permeate the questions concerning linguistic plurality existing there, and know how is ingrained in the discursive practices of the teachers the idea of cultural hegemony, monocultural curriculum and monolinguistico. To answer this question as theoretical and methodological contribution to discourse analysis is the construction of another look on language practices and resizing the object of analysis: the discourse of teachers.Tried to understand the discursive processes on educational practices of these teachers looking to analyze their ideological, social and discursive formation within a context of border. These professionals work in a bilingual reality where most of his students come from Lethem or indigenous communities, these being English speakers or an Indian language Macuxi indigenous, Wapixana and/or in addition to Portuguese. As a result of this study, it was found that in this nvironment, the teacher says not ready to cope with such reality, since there are educational programs in the municipality that endear this linguistic diversity and so little he says it is ready to act in this context as a result of higher institutions prepare it properly to deal with such a situation.

Full textEste trabalho tem por objetivo investigar como um contexto sócio-linguístico-cultural fronteiriço influencia na constituição do sujeito que ali mora e estuda. Esta é uma pesquisa orientada à luz da Linguística Aplicada, uma área de pesquisa que se interessa por novas teorizações e que dialoga com outras áreas do conhecimento, como Estudos Culturais e Sociolinguística. Esta pesquisa mostra-se pertinente à comunidade acadêmica e aos colegas professores atuantes no cenário educacional, por suscitar questionamentos acerca de sujeitos de minorias linguísticas, moradores na fronteira que convivem e interagem em um meio de dimensões culturais que se movimentam bidirecionalmente e, também se complementam, na perspectiva da transculturalidade. Trata-se de um estudo de cunho etnográfico com abordagem de pesquisa predominantemente qualitativa. Os registros foram coletados através da observação participante, do diário de campo e das entrevistas semiestruturadas gravadas apenas em áudio mediante a autorização dos sujeitos ou de seus responsáveis. Um total de 10 sujeitos foram entrevistados, sendo 8 alunos, 1 professor e 1 secretária da escola. As análises empreendidas indicaram a marcação da diferença e da identidade dos alunos pela língua.
This study aims to investigate how a socio-cultural-linguistic border context influences the constitution of the individual that lives and study there. This work is oriented under the bias of Applied Linguistics, a mixed area of research that is interested in new theories and dialogues with other areas of knowledge such as Cultural Studies and Sociolinguistics. This research is relevant to the academic community and to all the teachers that work in this educational system, by raising questions about linguistic minorities individuals, residents on the border who live and interact in an environment of cultural dimensions that moves bidirectionally and also complement each other, in the perspective of transculturality. This is an ethnographic study with predominantly qualitative research approach. The records were collected through participant observation, field diary and semi-structured interviews recorded in audio only with the permission of the individuals or their legal guardians. A total of 10 individuals were interviewed, 8 students, 1 teacher and 1 secretary of the school. The analysis undertaken indicated the marking of difference and identity of students by language.

Full textEconomic development was a key instrument in one of the crucial issues to the whole population and formulators of public policy: the improvement of living conditions of people and reducing poverty. The economic science teaches that the best way to achieve this condition is through political and economic settings. The urbanization of indigenous peoples is a growing phenomenon and this process has been giving with serious economic and social problems. In this context expresses the need to implement policies that meet differentiated according to their specific, given the cultural context that places them in a situation of vulnerability to economic and political pressures. To address this focus, this paper investigates the socioeconomic situation of indigenous people who live in Boa Vista, trying to relate and explain this situation from the point of view of economic science with the contribution of other social sciences. Thus, a search was described, along with a sample of 384 people living in Boa Vista who self-identify as indigenous, investigating issues related to marginalization, poverty and state of the labor market. The interdisciplinary approach that identifies the relationship between indigenous and non-indigenous in Boa Vista is mediated by specific values of inter-ethnic contact, leading to a syncretic elaboration of their knowledge and creating a cultural hybridization. Given this reality, it was possible to see that become victims from failures in the market due to lack of knowledge and information about its dynamics, living in extreme poverty, often located in remote areas of the city. Also discussed are policies that can promote the equating of this.

Full textOur Lady Consolata Church is the holly place made by Saint Vincents community in Boa Vista city, State of Roraima. This temple, built in 1983, by Consolatas missionaries helped by catholic folk who lives in the district where the church is situated, is the result of the many social cultural and religious processes for what this catholic community has passed by. This temple, considered the holly place, suffered actually a reform and reorganizational process of its space. Such process, besides modifying the ancient architecture of the temple, added new elements and symbols and redimensioned its space by giving to it a new architecture. This work has as objective to analyse this process of reform but mainly to reflect about the meaning of the symbols and icons which were added by the reform process. In this analyses we start from the principle which the temple is the most holly place into the Christian catholic experience and because this such place must have symbol elements for helping the communication between prayer believer and theirs worshipped the divine be. Therefore this reflection will be done by trying to understand the meaning of the geometrycal shapes of the temple and all icons in its interior side such as: Cristo Pantokrator, the cross, the mosaics of the altar and Virgin Consolata icon. To come true the analyses we used the qualitative search methodology by taking as investigative tools such elements: searches in archives and bibliographies, talking groups and interviews. All this search work made us to realize that the composition process of the social group of Saint Vincent Pauls district and of Our Lady Consolata Community were the result from several rights and wrongs that is also the result from exodus process which the people was submited (or submited themselves), printind this way, a particular character in that religious group. Understand itself, therefore, that to create a worship space, was the motivation for fighting for a life space too. And in these experiences the folk was descovering itself , it was raising roots and it was growing up as cultural social and religious group by conquering its territory, identity and suverving. Followed in this perspective, we can say that , in this case, the worship space become itself an essential factor, such as conquests expression as important tool in this historic process, result from their creativity and frequent re-meaning required by the life, maily, for a people which knew re-invent own culture and their symbols.

Full textIn 2005 a new recommendation was implemented, IAS 36 "Impairment of intangible assets". The Swedish translation of the recommendation is RR 17. The previous treatment of impairment of goodwill was to amortize it over a certain amount of years. In order for a company to make impairment, they had to estimate the decrease in value of goodwill to be permanent. The new recommendation RR 17 on the other hand states that goodwill should be impaired as soon as an indication of impairment loss is revealed. This implies that the new recommendation shows the fair value of goodwill. Our problem description is; how does the impairment procedure of goodwill in companies applying RR 17 look like?
In order to reach the purpose of this study, which is to understand the impairment procedure of goodwill, we used four sub questions; (1) How does goodwill arise? (2) How is goodwill divided between cash generating units? (3) How do stock listed business combinations in accordance with RR 17 estimate whether an impairment loss of goodwill exist or not, in cases where goodwill exist, how is it impaired? (4) How is goodwill revalued and how often?
The study has mainly taken a hermeneutic approach because we strive to understand the impairment procedure of goodwill. We conducted a qualitative study, with semi- structured interviews. Four companies, which operate in somewhat different branches, were chosen in order to get a diversified illustration of different business areas and see if there were any differences between them.
Our central concepts present general accounting principles as well as accounting principles handling impairment of goodwill, which helps the reader to receive a better understanding of the essential concepts concerning the impairment procedure of goodwill. In the analysis we connect our empirical findings with the central concepts in order to discover more dimensions of the impairment procedure of goodwill.
The result from our interviews showed that the companies follow the recommendation RR 17. However we could identify some differences between the companies, which we believe are due to the fact that the companies operate in different business areas and are therefore faced with somewhat diverse risks. Further we could link the differences to be correlated to the mindsets and demands of the companies’ auditors.
Finally we want to make the reader aware of the fact that the recommendation RR 17 has so far only been applied in an economic boom and therefore when we conducted this study the need to impair goodwill was very small.

Full textThe pension audit has been a hot topic for the listed companies for the last years. New rules have been applied which have caused discussions and difficulties for the companies. EU’s ministry of council accepted the so called IAS 2005 Regulation on the 7th June 2002. This means that all companies listed on the stock market must follow IAS regulations in their consolidated accounts latest 2005. RR 29 / IAS 19, grounds for our study, came into place already 1st January 2005. Svenska Redovisningsrådets Recommendation No 29, “Reimbursements to employees”, essentially corresponds to International Accounting Standard No 19, “Employee Benefits”.
The purpose with this graduate paper is to see what effects the transformation to RR 29 / IAS 19 has had on the companies capitalistic structure, i.e. how liabilities, equity and certain business ratio have changed for the researched companies on the A-list at Stockholm Stock Exchange.
We have chosen to use a quantitative method by studying annual reports and analyzing certain figures. The research strategy we use is a total investigative survey. This creates a portrayal in the form of descriptive statistics.
The total lump sum of RR 29 / IAS 19 is -11972,8m SEK .This amount is of course the same for equity as for liabilities, but viewed across the entire survey population the equity was a lesser amount than the net amount due. The majority of the researched companies had a negative lump sum, although a few had a positive lump sum. Two out of three ratios have increased in value.
Det senaste året har pensionsredovisning varit ett hett ämne för börsbolagen. Nya regler har tillkommit vilka har skapat diskussioner och svårigheter för företagen.
Den 7 juni 2002 godtog EU:s ministerråd den så kallade IAS 2005 förordningen. Denna innebär att alla börsnoterade bolag senast 2005 skall följa IAS anvisningar i sin koncernredovisning. Redan från och med 1 januari 2004 började RR 29/ IAS 19, underlaget för vår studie, att gälla. Svenska Redovisningsrådets Rekommendation nr 29 ”Ersättningar till anställda” överensstämmer i all väsentligt med International Accounting Standard nr 19 ”Employee benefits”.
Syftet med denna kandidatuppsats är att se vilka effekter övergången till RR 29 / IAS 19 har haft på företagens kapitalstruktur, alltså hur skulder, eget kapital och särskilda nyckeltal har förändrats för de undersöka företagen på A-listan.
Vi har valt att använda oss av en kvantitativ metod genom att studera årsredovisningar och analysera viss sifferdata. Forskningsstrategin vi använder oss av är en surveyundersökning i totalundersökningsformat. Detta skapar sedan en framställning i form av deskriptiv statistik.
Den totala engångseffekten av RR 29 / IAS 19 blev -11972,8 miljoner kronor. Summan var självklart densamma för eget kapital som för skulder, men totalt sett över hela undersökningspopulationen var det egna kapitalet en mindre summa än nettoskulden. Majoriteten av de undersökta företagen fick en negativ engångseffekt, dock var det ett fåtal som fick en positiv engångseffekt. Två av tre nyckeltal har fått ett mer positivt värde.

Agrarian Reform has been implemented in Brazil through the National Institute of Colonization and Agrarian Reform - INCRA, since 1970, through the establishments of families in areas of the Union. In the specific case of the rural establishments which are located in tropical forest, the INCRA has been adopting the same procedure used in other areas of Brazil that it consists of motivating the subsistence agriculture on short scale. However, specifically in the Amazon region, the procedure requests cutting and burning of forest that generates a considerable environmental impact. Evidence is the Report of Deforestation in Amazon region by Brazilian Environmental Institute - IBAMA of October of 2008, which identifies INCRA as most responsible by the increasing deforestation in Amazon forest. In this case, the research has intended to value, economically, the environmental impacts of productive activities in two rural establishments, which are located in the km 460 on the Federal Highway, BR-174, district of Rorainópolis (RR). Both places have been chosen because they have rainforest characteristics, they are located close to city and the rural establishments began to operate at the same time. The Contingent Valuation Method (MVC) has been used on the research. The MVC is based on the willingness to pay (WTP) and the willingness to accept (WTA) of people on respect to value the environmental assets and liabilities generated by the enterprises. The research has been consisted of 55 questionnaire applications on the family units to value the WTP, which is associated to environmental impacts of their production activities. In accordance with the obtained data, it can identify the subsistence agriculture with corn, rice and cassava; as the main production activities in both rural establishments. The mapping of productive processes of those activities has shown that they request the cutting and the burning of forest. In accordance with the obtained results, it could be concluded that after the inclusion of the costs and environmental benefits in the analysis of the local one presented a monthly WTP of R$ 79,08, and total WTP of R$ 1.977,00. The local two presented a monthly WTP of R$ 87,84, and total WTP of R$ 2.635,20. Those results are reflex of the low level of income observed in the area, on average of R$ 380,00 associate at a low level of information of the local population regarding the profitability obtained with alternatives of maintainable exploration of the forest in foot. In that sense it suggests that after the establishment of the families in forest areas done an information work and should be given a technician and financial support. That could be made possible in the area through a partnership among INCRA, EMBRAPA and BASA. It is a challenge does not to leave the population alone, which wrapped up in an integral and conscious way, it is necessary to give continuity to do not lose the hopes in real actions to build the local environmental citizenship.
A Reforma Agrária tem sido realizada no Brasil através do Instituto Nacional de Colonização e Reforma Agrária – INCRA, desde 1970, por meio do assentamento de famílias em áreas da União. No caso específico de assentamentos localizados em áreas de floresta tropical, o INCRA tem adotado o mesmo procedimento usado em outras regiões do Brasil, que é o de incentivar a agricultura de subsistência em escala familiar. Porém, especificamente na Amazônia, esse procedimento requer o desmatamento e a queima da floresta, o que gera considerável impacto ambiental. Uma constatação disso é o Relatório de Desmatamento na Amazônia do Instituto Brasileiro do Meio Ambiente - IBAMA, de outubro de 2008, que identifica o INCRA como o maior responsável no aumento do desmatamento da floresta Amazônica para o período analisado. Neste sentido, a pesquisa se propôs a valorar economicamente os impactos ambientais decorrentes das atividades produtivas em dois assentamentos rurais localizados nas proximidades do km 460 da rodovia BR-174, no município de Rorainópolis (RR), propositalmente escolhidas por terem características distintas de floresta tropical, situadas próximas ao núcleo urbano e terem o mesmo tempo de existência. Na pesquisa utilizou-se o Método de Valoração Contingente que se baseia na disposição a pagar (DAP) e a receber (DAR) dos indivíduos no que diz respeito a valorar os ativos e passivos ambientais gerados nos empreendimentos. A pesquisa constituiu-se da aplicação de 55 questionários nas unidades familiares para valorar a DAP decorrente dos impactos ambientais relacionados às atividades da agricultura familiar de subsistência praticada na região, como por exemplo, cultivo de milho, arroz e mandioca. De acordo com os dados obtidos, a Área um contou com 25 entrevistados e apresentou uma DAP de 79,08/família/ano e total de R$ 1.977,00/ano; a Área dois contou com 30 entrevistados e apresentou uma DAP R$ 87,84/família/ano e total de R$ 2.635,20/ano. Esses resultados refletem o baixo nível de renda observado na região, em média de um salário mínimo associado a um baixo nível de informação atualizada sobre a população local, a respeito da rentabilidade obtida com alternativas de exploração sustentável da floresta ainda intacta. Nesse sentido, sugere-se que seja realizado um trabalho informação, apoio técnico e financeiro desde o início do assentamento das famílias. Isso poderia ser viabilizado na região através de uma parceria entre o INCRA, IBAMA, a EMBRAPA e o BASA. É um desafio para a gestão pública dar continuidade ao processo de fixação das famílias e não deixar a população, que se envolveu de forma tão integral e consciente, perder as esperanças diante das dificuldades enfrentadas.

Full textO Estado de Roraima apresenta uma heterogeneidade de feições geomorfológicas, que corroboram na constituição de uma paisagem singular na região amazônica. Notam-se, feições geomorfológicas constituídas por planaltos dissecados, ladeados por pediplanos intramontanos, assim como, relevos residuais que apontam nas extensas áreas planas. Essa notável variedade de unidades de relevo é reflexo da interação de fatores endógenos e exógenos atuantes nas eras geológicas dentro dos domínios litoestruturais. Dentro deste panorama, encontra-se a região da Serra da Lua, cujas feições geomorfológicas se destacam no cenário paisagístico regional, por constituir um planalto residual inserido na unidade denominada de Planaltos Residuais de Roraima, ladeado a uma morfologia colinosa pertencente a unidade do Planalto Dissecado Norte da Amazônia e áreas aplainadas do Pediplano Rio Branco Rio Negro. Nota-se, portanto, a importância dos estudos geomorfológicos diante de toda essa dinâmica morfoestrutural das formas terrestres, principalmente diante do poder das alterações ocasionadas pela ação do homem na paisagem amazônica que tem sido motivo de preocupação no que diz respeito às transformações das paisagens naturais. O uso do geoprocessamento vem como aporte neste trabalho, pelo qual proporcionará o conhecimento da distribuição e comportamento da unidade geomorfológica. As geotecnologias proporcionam uma análise mais detalhadas dos objetos estudados. A geomorfologia aliada às geotecnologias surge como um poderoso campo de estudo, visto que proporciona um papel fundamental na análise da paisagem.Esta pesquisa objetivou a análise das feições morfoestruturais da Serra da Lua, com o auxílio de fotointerpretação em imagens de sensores remotos complementado com análises in loco, de forma a mapear e classificar as feições geomorfológicas que compõe esta paisagem. No qual pode-se identificar as formas de relevo associados aos patamares estruturais identificados em modelados de acumulação e dissecação classificados de acordo com a nomenclatura proposta do IBGE em: Patamar em Crista Estruturado (PCRE); Maciço Somital Convexa (MSC); Morros e colinas escalonados com vales abertos (MEVA) e Serranias em vales encaixados (SVE), caracterizados como modelados de dissecação. Os modelados de acumulação foram identificados na região sendo caracterizados como Superfícies aplainadas (SAP) e Superfícies Aluvionares (SA).
The State of Roraima presents heterogeneity of geomorphological features, which support the creation of a unique landscape in the Amazon region. Note the, geomorphological features consist of plateaus dissected, flanked by pediplanos intramountains as well as residual relief that point in the extensive flat areas. This remarkable variety of relief units reflects the interaction of endogenous and exogenous factors working in the geological ages within the lithostructural areas. Within this panorama, is located the region of Serra da Lua, whose geomorphological features stand out in the regional landscaped setting, for being the residual plateau inserted into the unit called the Residual Plateaus of Roraima, flanked a hilly morphology belonging to unit Plateau Dissected northern Amazon and flattened areas of pediplano Rio Branco - Rio Negro. Note, therefore, the importance of geomorphological studies before all this morphostructural dynamics of landforms, especially at the power of the changes caused by human activities in the Amazon landscape that has been of concern with respect to the transformations of natural landscapes. The use of geoprocessing comes as contribution in this work, for which will provide the knowledge of the distribution and behavior of the geomorphological unit. Geotechnologies provide a more detailed analysis of the studied objects. The geomorphology combined with the geotechnologies emerges as a powerful field of study as it provides a key role in landscape analysis. This study aimed to analyze the morphostructural features of the Serra da Lua, with the aid of photo-interpretation in remote sensing complemented by in loco analysis in order to map and classify the geomorphological features that make up this landscape. In which one can identify the landforms associated with structural levels identified in modeled accumulation and dissection classified according to the IBGE proposed nomenclature: Porch in Structured Crest (PCRE); Massive Somital Convex (MSC); Hills and hills staggered with open valleys (MEVA) and mountainous areas in enclosed valleys (EVS), characterized as modeled dissection. The modeled accumulation were identified in the region being characterized as planed surfaces (SAP) and Surface Alluvial (SA).

Full textThis dissertation wants to assess the meaning and value of liberating education from the concept of community experience, an experience that is democratic and, therefore, inform a spirit citizen in students. We leave the theoretical contributions of Paulo Freire and Moacir Gadotti. Evaluate the influence of reading that Anísio Teixeira makes the work of John Dewey, and its consequent influence on the construction of democratic education postulated by Freire. Similarly, we will build the text considering the experiences of Anísio Teixeira and Centro Educacional Carneiro Ribeiro: Escola Parque, in Bahia, in 1950; consequently this historical experience, listed the proposal for a project of contemporary community education, a project developed in municipal schools in Boa Vista, Roraima.

Full textPatients diagnosed with rifampicin resistant (RR) tuberculosis (TB) in South Africa frequently fail to link to appropriate drug resistant (DR) TB treatment. The aim of this study was to explore barriers and enablers to expedited linkage to treatment following RR-TB diagnosis in the Western Cape Province, within the context of ongoing decentralisation of DRTB services and the scale-up of Xpert MTB/RIF diagnostics. Methods: An embedded case study approach, using qualitative research methods, was employed to explore barriers and enablers to expedited treatment linkage following RR-TB diagnosis. The case of investigation in this study was 'treatment linkage following RR-TB diagnosis in the Western Cape Province during the ongoing decentralisation of DR-TB services and scale-up of Xpert diagnostics'. DR-TB is used in this study as an encompassing term to refer to RR, multidrug resistant and extensively drug resistant TB. The embedded units of analysis in this study were patients' linkage outputs, defined as: (1) expedited treatment initiation, (2) delayed treatment initiation and (3) non-initiation of treatment following sputum collection on which RR-TB was diagnosed. Seventeen patient, 8 family member, 49 healthcare worker and 4 key informant open-ended, in-depth interviews were conducted and 59 patient folders were reviewed. Additionally, an extensive literature review was conducted. The tools used for data collection in this study were developed from the literature review and Coker et al.'s (201) conceptual framework for evaluation of a communicable disease intervention. A framework approach using Coker et al.'s conceptual framework was applied for analysis. Results: This study identified multiple factors that enabled and constrained expedited treatment linkage following RR-TB diagnosis. Enabling factors included: 1) the availability of clinic level DR-TB counsellors and tracers; 2) living in walking distance of decentralised services and 3) having a strong social support network. Constraining factors included: 1) low usage of Xpert diagnostics, 2) delays in acting on results and missed (or unseen) results, 3) rotation of nurses or the lack of dedicated TB nurses in clinics, 4) limited clinic-level administrative support, 5) information systems challenges and 6) waiting lists for beds and limited access to transport services in rural areas . In linking to treatment, patients commonly face challenges due to competing subsistence needs and household or employment responsibilities. Additionally, substance addiction, having a history of treatment interruption, hopelessness regarding treatment, as well as not having a stable place to stay or social support may increase patients' risks of linkage failure. Conclusion: Within the Western Cape Province, there is significant opportunity to improve linkage to treatment through strengthening the health systems mechanisms to link patients to treatment following RR-TB diagnosis. Expanding access to psychosocial services (substance abuse rehabilitation and psychosocial evaluations) following RR-TB diagnosis may assist in linking high-risk patients to treatment. Additionally, the provision of food support (in addition to social grants) should be evaluated as a tactic to improve treatment linkage and adherence.

The region of the lower Rio Branco is located south of the city of Caracaraí in the state of Roraima, where for more than a decade has been developing fishing tourism activities within the Environmental Protection Area (EPA) Xeriuini. The Vila Terra Preta is inserted in this EPA and its residents have hired to work as fishing guides in tourist activity. This study aims to: identify the profile of the residents of the Vila Terra Preta; assess what stage of development of the activity of fishing tourism practiced in the Lower Rio Branco region; identify the interference caused by the activity of fishing tourism that affect the living conditions of the residents of Vila Terra Preta; analyze the responsiveness and involvement of indigenous in relation to activities undertaken by tourism operators in the region. Made use of a questionnaire as a tool for exploratory research with quantitative and qualitative approach, achieving results that show positive interference as the generation of jobs and income supplement, even if those jobs are temporary jobs. But, on the other hand harmful interference to fish population due to the equipment used by tourists/fishermen, perceived by some locals. Also tourism has not contributed to improvements in community infrastructure and the management respondents consider themselves excluded from decision- making and participation in the organization of tourism.

Full textFor correct specification human’s physiological state, it is very important to evaluate the changes of main human organism systems. In this paper, the parameters that characterize the function of periphery, regulation and supplying systems, JT and RR interval have been studied. Interpolation of discrete data from the physical load obtained by provocative incremental bicycle ergometry stress test was made by cubic spline. The differences for various groups of person (sportsmen and patients with ischemic heart disease) were investigated. EKG parameters were applied in three methods: EKG parameters changes in speed computing and imaging in phase plane, EKG parameters smoothness level calculation, EKG parameters data grouping method. The study revealed that the JT interval’s changes in speed reliably differences between healthy and ill people. Also JT parameter’s smoothness level and JT parameter’s discriminants difference between the groups.

Full textIn corn crop, postemergence herbicides have been widely used because of its efficacy, convenience and cost feasibility. The objective of this study was to evaluate the phytotoxicity of herbicides used in post-emergence, and their interference in the productivity of corn hybrids. The experiment was conducted at the Federal Institute of Education, Science and Technology IFSULDEMINAS, campus Machado. Was used a randomized block experimental design (RBD) with 6 treatments and 4 repetitions, totaling 24 plots. For this, were used two hybrids with similar size and characteristics: Hybrid 1 VT PRO 1 and hybrid 2 VT PRO 2. The hybrid 1 presents the transgenic event of resistance to fall armyworm (Spodoptera frugiperda) and the hybrid 2 shows the same transgenic event of resistance to fall armyworm (Spodoptera frugiperda) and to roundup, called Roundup Ready (RR). Were used six different treatments in hybrids, in the hybrid VT PRO 1 with resistance to fall armyworm were applied herbicides, atrazine + tembotrione (triazines + benzoilciclohexanodiona); nicosulfuron + atrazine (triazines + sulfonylurea); mesotrione + atrazine (triazines + tricetonas) and control treatment where no herbicide was applied. For the hybrid VT PRO 2 with resistance to fall armyworm and the roundup was applied herbicide atrazine + glyphosate (triazines + substituted glycine) and control treatment without herbicide application. Treatments were weeded manually during all the experiment conduction. There was incidence of lightweight phytotoxicity with leaf lesions below 7%, which reduced up to 28 DAA. The combination of atrazine with tembotrione or nicosulfuron reduced corn productivity in 1.066 and 1.122 kg ha-1 respectively. The application of atrazine + mesotrione in hybrid VT PRO 1 and glyphosate in hybrid VT PRO 2, compare to their control treatments, did not affect production. However, the productivity in the hybrid VT PRO 1 was greater than the hybrid VT PRO 2, a result which was not expected to equal hybrids with different events. It was observed in all treatments productivity above 10 tonnes ha-1. The combination of herbicides leads to the emergence of phytotoxicity minor injuries; Atrazine in combination with tembotrione or nicosulfuron reduces corn productivity.
Na cultura do milho a utilização de herbicidas pós-emergentes tem sido muito utilizado, devido sua eficácia, conveniência e viabilidade de custos. Objetivou-se com o presente trabalho avaliar a fitotoxicidade de herbicidas usados em pós-emergência, bem como a sua interferência na produtividade em híbridos de milho. O experimento foi conduzido no Instituto Federal de Educação, Ciência e Tecnologia IFSULDEMINAS, campus Machado. Foi utilizado o delineamento de blocos ao acaso (DBC), com 6 tratamentos e 4 repetições, totalizando 24 parcelas. Para tanto, foram utilizados dois híbridos de porte e características similares: Híbrido 1 VT PRO 1 e híbrido 2 VT PRO 2. O híbrido 1 apresenta o evento de transgenia de resistência a lagarta do cartucho (Spodoptera frugiperda) e o híbrido 2 apresenta o mesmo evento de transgenia de resistência a lagarta do cartucho (Spodoptera frugiperda) e também ao roundup, denominado Roundup Ready (RR). Foram utilizados seis tratamentos diferentes nos híbridos, sendo que no híbrido VT PRO 1, com resistência a lagarta do cartucho foram aplicados os herbicidas, atrazine + tembotrione (triazinas + benzoilciclohexanodiona); atrazine + nicosulfuron (triazinas + sulfoniluréias); atrazine + mesotrione (triazinas + tricetonas) e tratamento testemunha em que não foi aplicado nenhum herbicida. Para o híbrido VT PRO 2, com resistência a lagarta do cartucho e ao roundup foi aplicado o herbicida atrazine + glyphosate (triazinas + glicina substituída) e o outro tratamento que foi a testemunha sem aplicação de herbicidas. Os tratamentos foram capinados manualmente durante toda condução do experimento. Houve incidência de fitotoxicidade denominada leve, com lesões foliares abaixo de 7%, as quais reduziram até os 28 DAA. A combinação de atrazine com tembotrione ou nicosulfuron reduziu a produtividade do milho em 1.066 e 1.122 Kg ha-1 respectivamente. A aplicação da combinação atrazine + mesotrione no híbrido VT PRO 1, bem como o glyphosate no híbrido VT PRO 2, perante suas testemunhas não afetaram a produção. Porém, a produtividade no híbrido VT PRO 1 foi maior do que o híbrido VT PRO 2, resultado este que não era esperado, para híbridos iguais com eventos diferentes. Foi observado em todos os tratamentos produtividade acima de 10 toneladas ha-1. A combinação dos herbicidas testados leva ao surgimento de lesões leves de fitotoxicidade; Atrazine em combinação com tembotrione ou nicosulfuron reduz a produtividade do milho.

Los resultados de la búsqueda de RR Lyrae con estos datos fueron nulos. Ante estos resultados realizamos observaciones simuladas de RR Lyrae, bajo las mismas condi- ciones de los datos observados, demostrando que la cadencia utilizada en las observaciones no permite la identificación del período de las estrellas RR Lyrae. Finalmente probamos el método desarrollado con datos de HiTS (High Cadence Tran- sient Survey), una campaña dedicada a detectar transientes en el óptico, principalmente las primeras horas de las explosiones de supernovas. Luego de responder favorablemente a las observaciones simuladas, logramos identificar en los datos de HiTS 2015A un total de 106 RR Lyrae 7 de las cuales se encuentran a una distancia mayor a 100 kpc.

The source spectrum is better explained with photoionized plasma model rather than the cooling flow model. It has also been found that the neutral Hydrogen column density differs for orbital minimum and orbital maximum spectra with values 0.25 (+0.23 -0:18)*10^22 atoms/cm2 and 0.64 (+0.13 -0.14)*10^22 atoms/cm2 respectively at 3 sigma confidence level. The difference of neutral Hydrogen column density between the maximum and minimum phase spectra indicates existence of a warm absorbing region on the disc at the location of the impact zone.

Full textBakgrund: Redovisningsrådet, som utfärdar svenska redovisningsrekommendationer, publicerade i augusti 2000 rekommendation nr 17, Nedskrivningar. Syftet med rekommendationen är att visa på vilka värderingsmetoder som ska gälla för att säkerställa att tillgångar inte är redovisade till ett för högt värde. Rekommendationen trädde i kraft den 1 januari 2002. Avgivna årsredovisningar för 2002 är därmed första gången rekommendationen måste tillämpas. RR 17 är en översättning av en internationell standard, i detta fall IAS 36, vilken publicerades i juni 1998 av dåvarande IASC (International Accounting Standards Committee). Före RR 17 var det FAR:s rekommendation om redovisning av materiella anläggningstillgångar som innehöll ett avsnitt om nedskrivningar. Avsnittet i FAR 3 innehöll formuleringar liknande de i IAS 36.
Syfte och frågeställningar: Uppsatsens syfte är dels att undersöka vilka skillnader införandet av RR 17 har medfört för företagens värderingsrutiner av tillgångar, dels hur informationen i årsredovisningen förändrats. Vi avser också att undersöka om införandet inneburit förändringar i revisorernas granskningsrutiner avseende nedskrivningar. Våra tre frågeställningar är: Vilka skillnader har införandet av RR 17 medfört för svenska företag i värderingsprocessen av sina tillgångar? Hur har informationen i företagens årsredovisning förändrats efter införandet av RR 17? Hur har införandet av RR 17 påverkat revisorernas granskningsrutiner avseende nedskrivningar?
Avgränsningar: Vi har valt att avgränsa oss till nedskrivningar av immateriella tillgångar såsom goodwill och patent, samt nedskrivningar av materiella tillgångar. Finansiella tillgångar tas inte upp. Med revisorernas granskningsrutiner avses enbart den granskning som utförs på nedskrivningar av tillgångar enligt RR 17.
Genomförande: I undersökningen har tre metoder för datainsamling använts. Dessa är litteraturstudier, fyra intervjuer samt studie av fyrtio årsredovisningar, två per företag.
Resultat: Tillämpningen av RR 17 har inte medfört några principiella skillnader vare sig för företagen eller för revisorerna. Till yttermera visso kan dock vissa, mindre förändringar skönjas. Den största förändringen som vi observerar i denna uppsats är att RR 17 innebär en mer detaljerad rekommendation än tidigare, vilket ökar kraven på företagens dokumentation i samband med värderingen av tillgångarna. Det har i sin tur förändrat revisorernas granskningsrutiner i den meningen att revisorn har bättre stöd för att kräva av företagen att genomföra värderingen på ett sätt som överensstämmer med rekommendationen.

Frente a dúvida sobre a nutrição da soja com manganês influenciada pelo glyphosate e a inclusão do gene de resistência, objetivou-se estudar o acúmulo e distribuição do nutriente na planta de soja geneticamente modificada sob efeito da aplicação de glyphosate, assim como a cinética de absorção do Mn pela soja transgênica sob ação do mesmo herbicida. Foram conduzidos dois experimentos em casa de vegetação no Departamento de Produção Vegetal - Agricultura da Faculdade de Ciências Agronômicas, UNESP-Botucatu. Experimento 1: Em delineamento de blocos completos ao acaso e em esquema fatorial 5 x 3, com quatro repetições, a absorção e o acúmulo de Mn foram avaliados em duas cultivares de soja quase isogênicas (Conquista e Valiosa RR), cultivadas em solução nutritiva. Foram empregados os seguintes níveis de Mn à solução nutritiva: 0; 0,085; 0,125; 0,250; 0,500 mg L-1. Após 25 dias de cultivo as plantas de soja transgênica, destinadas ao estudo sob efeito do glyphosate, foram submetidas à aplicação do herbicida, formulado a base do sal de isopropilamina, via foliar, na dose de 720 g e.a. ha-1. Todas as plantas de soja, convencional e transgênica, com e sem a adição do herbicida, foram coletadas na mesma data (15 dias após a aplicação do herbicida). Realizaram-se divisões das plantas em raízes, hastes e folhas, para a determinação da massa de matéria seca (MMS) e os teores de Mn. Experimento 2: O estudo da cinética de absorção do Mn pela cultivar Valiosa RR foi organizado em delineamento de blocos completos ao acaso, com sete repetições.

Faced with questions about the nutrition of soybean with manganese influenced by glyphosate and the inclusion of the resistance gene, it was aimed to study the accumulation and partition of nutrient in soybean plant genetically modified under effect of glyphosate and the kinetics of Mn absorption by soybean GM under the action of the same herbicide. It was run two experiments in a greenhouse at the Department of Plant Production, Faculty of Agronomic Sciences, UNESP-Botucatu. Experiment 1: In a randomized complete block design and in a 5 x 3 factorial scheme, with four replications, the absorption and accumulation of Mn was evaluated in two cultivars of soybean near-isogenic (Conquista and Valiosa GR), that was grown in nutrient solution. The following Mn levels of the nutrient solution were utilized: 0, 0.085, 0.125, 0.250, 0.500 mg L-1. After 25 days of GR soybean plants cultivation, the leaves of soybean were sprayed with glyphosate formulations on the basis of isopropylamine salt using 720 g a.e. ha-1. All soybean plants, conventional, GR, with and without glyphosate, were collected on the same date (15 days after herbicide application). Then they were separated by roots, stems and leaves, for the determination of dry matter and Mn concentration. Experiment 2: The experiment was randomized using complete block design with seven replicates studying the kinetics of Mn uptake by GR Valiosa soybean cultivar under doses of glyphosate. After 26 days of soybean cultivation the glyphosate was applied with the same wording of the previous experiment, using doses of 0 (zero), 15 and 960 g a.e. ha-1 doses. Using the technique of Mn exhaustion from the nutrient solution after four days of herbicide application, it was carried out a study of the kinetics of Mn absorption.

Full textSince the 1960s, violence among the Yanomami has been one of the most polemical research topics in South American Ethnology, giving rise to a debate that has drawn contributions from the areas of ecological anthropology, sociobiology and genetics as well as archaeology, gender studies and political philosophy. Through an analysis of ethnographic data collected among the Yanomami of the Serra das Surucucus (Roraima, Brazil), this thesis demonstrates the ways in which the Yanomamis system of aggressions relates to their kinship system, their settlement patterns and their definition of social units. The relations between these units, for their part, are analysed through their interface with Yanomami funeral practices and cosmology, fundamental elements in the investigation of the phenomenon of Yanomami aggression and for the understanding of the dynamic of approach and withdrawal that characterizes this system.

The Mucajaí Gneiss, Serra da Prata Charnokites, San Antonio and Pratinha Gabbros units of exhibit Sn gneissic and S1 mylonitic foliation, with deformation microstructures generated under medium to high amphibolite facies temperature conditions. Despite the obliteration of primary structures, some igneous microstructures preserved in granitoids and gabbros, such as preferred orientation of feldspar phenocrysts with crystal faces due to magmatic flow, submagmatic microfractures and dike intrusion controlled by pre-existing anisotropy (Pre-S1), suggest syn-magmatic deformation processes. U-Pb SHRIMP analysis of oscillatory zones of igneous zircons provided Concordia ages of 1916.7+4.5 Ma for a mylonitized granite of Serra da Prata Charnokites, 1905+5.2 Ma for associated gabbros and 1959+5 for orthognesis of Mucajaí Gneiss. These ages are interpreted as the crystallization ages of the protoliths and understood as the age of the tectono-magmatic event that probably controlled the emplacement of most of the granitic rocks of Serra da Prata Suite and associated gabbros. Another U-Pb SHRIMP age of 1863+6.7 Ma recorded in dynamically recrystallized zones of zircons from mylonitized granite is related to the metamorphic-deformational event that generated the foliation S1 and probably related to the generation of the Sn foliation. Reworking of deformational structures is interpreted by the presence of mylonitic recrystallized bands oriented parallel to S1 and oblique to Sn foliations. Temperature conditions for this deformation event, characterized by grain size reduction of the of the crystals, is assumed equivalent to upper green schists to medium amphibolite facies and interpreted as tectonic reactivation at shallow crustal levels under a regional stress field similar to that responsible for the registration of the foliation S1 and related to K’Mudku event. Magnetic mineralogy studies indicate that the principal magnetic marker of magnetic subfabrics in granitoids and gabbros is magnetite multidomain. At Sierra da Prata Charnokites magnetic sub-fabrics display a magnetic foliation oriented preferentially NE-SW. On the other hand, the Pratinha Gabbros display a random orientation of the magnetic foliation that is related to the heterogeneous distribution of deformation, concentrated along the margins with high dip angles and high values of magnetic anisotropy Pj (high strain). Less intense deformation was found at the center of the gabbroic body that displays sub-horizontal magnetic foliation with low values of magnetic anisotropy Pj (low strain). Given the nature of the internal deformation and the arrangement of the magnetic sub-fabrics, it is interpreted that S1 and Sn rock fabrics were produced by deformation under medium to high amphibolite facies temperature conditions related to dextral transpressional regime induced by NW-SE shortening active during the Paleoproterozoic.
As rochas das Unidades Gnaisse Mucajaí e Charnockito Serra da Prata exibem uma foliação Sn gnáissica e S1 milonítica, com microestruturas de deformação geradas sob condições de temperatura da fácies anfibolito médio a alto. A despeito da obliteração das estruturas primarias em granitóides e gabros, se preservam algumas estruturas ígneas, como fenocristais de feldspato com faces cristalinas conservando a orientação herdada do fluxo magmático, microfraturas magmáticas, intrusão de diques controlados por anisotropia preexistente (Pre-S1) sugerindo processos de deformação sin-magmática. Análises U-Pb SHRIMP em zircão em áreas com zoneamento oscilatório, forneceram idades concórdia de 1.916,7 ± 4,5 Ma para a um granito milonitizado da unidade Chanockito Serra da Prata, 1905 ± 5,2 Ma em gabro associado e 1959 ± 5,2 Ma para um ortognaisse do Gnaisse Mucajaí, interpretadas como a idades de cristalização dos protólitos e entendida como idade do evento tectôno-magmático que provavelmente controlou a instalação dos granitóides da Suíte Serra da Prata e gabros associados. Outra idade U-Pb SHRIMP de 1863 ± 6,7 Ma em zonas de recristalização dinâmica em zircões extraídos de uma amostra do granito milonitizado estaria datando o evento metamórfico-deformacional responsável pelo registro da foliação S1 e provavelmente conexa à geração da foliação Sn. As petrotramas da foliação milonitica S1 e Sn gnáissica foram retrabalhadas por bandas de recristalização miloníticas orientadas paralelamente à petrotrama S1 e obliquamente à estruturação Sn. Este evento deformacional é caracterizado pela redução do tamanho dos cristais em condições de temperatura das fácies xisto-verde superior a anfibolito médio, interpretada como uma reativação tectônica em nível crustal mais raso sob um campo de esforço regional similar ao responsável pelo registro da foliação S1 e relacionado ao evento K’Mudku. Estudos de mineralogia magnética indicam que a magnetita multidominio é o marcador magnético dominante da subtrama em granitóides e gabros. A subtrama magnética do plúton Charnockito Serra da Prata determina uma foliação magnética orientada preferencialmente NE-SW. No gabro Pratinha a foliação magnética apresenta uma disposição aleatória relacionada à distribuição heterogénea da deformação, concentrada nas bordas do corpo com mergulhos altos nas bordas do corpo e valores altos de anisotropia magnética Pj (high strain) e menor intensidade da deformação no centro exibindo foliação magnetica sub-horizontal com baixos valores de anisotropia magnética Pj (low strain). Dado o caráter da deformação interna e o arranjo da subtrama magnética, se entende que as petrotramas temperatura S1 e Sn foram geradas sob condições de temperatura das fácies anfibolito médio a alto relacionado com um regime transpressivo dextral induzido pelo tensor de encurtamento NW-SE ativo no paleoproterozoico

Full textO município de Mucajaí (área foco deste estudo) está situado na região centro-oeste do Estado de Roraima. A análise da paisagem do município de Mucajaí (objeto desse estudo) teve como enfoque os aspectos geológicos e geomorfológicos e o seu potencial para o geoturismo. Para o desenvolvimento da pesquisa, fez-se necessário o levantamento de material bibliográfico, cartográfico e de sensores remotos, bem como atividades de campo com intuito de identificar e descrever os compartimentos geomorfológicos que posteriormente foram cartografados. Como resultado obteve-se a descrição da paisagem no seu contexto geológico e geomorfológico em que identificou-se os modelados de denudação e acumulação. A compartimentação estudada revelou as seguintes unidades: Relevo em Crista Estruturado, essa unidade representa um relevo de erosão diferencial, recoberto por vegetação do tipo Floresta Ombrófila Densa; sobressaíram-se feições como serras, cachoeiras; na Superfície Somital Convexa, distribui-se de forma pontual e isolada por toda superfície aplainada maciços que ocorrem isoladamente, denominados relevos residuais além do Relevo Convexo Estruturado. As áreas rebaixadas são representadas pelas Superfícies Aplainadas e Aluvionares. A paisagem da área estudada revela um grande potencial para a atividade geoturística, a exemplo de serras e morros alinhados e as belas cachoeiras. Portanto, o potencial paisagístico repleto de belezas cênicas naturais favorecem à grandes possibilidades de implantação da atividade geoturística, a partir das iniciativas existentes no município e de um planejamento direcionado a valorização do potencial para sua efetiva operacionalização.

A migração de nordestinos para Roraima é caracterizada por redes sociais resultantes de uma corrente migratória. Este trabalho teve como objetivo identificar os motivos que levaram tantos nordestinos a traçar essa longa trajetória. Para tanto, foram aplicados questionários e realizadas entrevistas na cidade de Boa Vista, cidade que se destaca pela dinamicidade da infraestrutura e pela fronteira geopolítica. Num primeiro momento, foram analisadas as correntes migratórias existentes no país, destacando os fatores responsáveis por esse movimento. Em seguida foi realizado um levantamento da historicidade da migração no Nordeste, ressaltando o papel dos nordestinos como fornecedor de mão-de-obra a nível nacional, sob a ótica dos efeitos da seca. Também foi avaliado o papel da migração como deslocamento de força de trabalho do semi-árido para abrir fronteira na região equatorial, provocando uma adaptação a um novo ambiente físico e cultural totalmente diferente. A migração se faz em trajetórias variadas, expondo o migrante a múltiplas adversidades, como o câmbio da vida de agricultor a explorador de minas ou trabalhador urbano. O papel do migrante nordestino é destacado pela sua capacidade de (re) produzir seu espaço, tanto cultural como economicamente, em terras distantes, impondo territorialidades. Verificou-se o efeito que a migração exerce sobre o crescimento do capital e da força de trabalho no Estado de Roraima, ponto extremo do norte da Amazônia Brasileira, onde o nordestino é reconhecido pelo seu trabalho, pelo crescimento do comércio na economia roraimense, recebendo em troca uma sensível melhoria na qualidade de vida, algo tão almejado pelo sertanejo.

This work aimed to identify the reasons that made such a large quantity of “nordestinos” migrate to Roraima. In order to achieve this goal, questionnaires and interviews were held in Boa Vista, city recognized by its dynamic infrastructure and geopolitical situation. At first, migratory flows occurring in the whole country and its reason, were analyzed. Then it was made a historical survey of migration in the northeast standing out the function of northeastern people as a labor fountain for the country, as a result of the dry climate effects on the region. It was also observed the whole of migration as a movement of labor force from semiarid to new frontiers in the equatorial region, provoking adaptation to new physical and cultural situations. Migration occurs in different ways, exposing the migrants to multiple adversities, like changing from agriculturist into miner explorer, urban worker. The migrants from Nordeste are known for their capacity to rebuild their space, cultural and economically in long distance lands, imposing territoriality. It was verified the effect of migration on the growth of the capital, Boa Vista, and its labor force in the state, located in the extreme north of Amazon region, where “nordestinos” are recognized for their labor activities and for the growth of commerce in Roraima economy. In change, Roraima give “nordestinos” better life quality.
