Escolaridade de professores atuantes na educação infantil da cidade de Irati Estado do Paraná

The present study had as the main purpose to verify the teacher’s formation who update in the child education institutions of the Irati city (Parana State – Brazil), throughout the years of 2005, 2006 and 2007, and their implications for the pedagogical actions. Seven institutions they had participated of the study. The data collection was made by means of documents of the institutions. A predominance of secondary school in the formation of the teachers was verified, even so had still one high index of professionals with formation level below of this requirement to the legislation. We conclude that it has urgency to the implementation of public politics directed toward the child education, with focus for the formation’s teachers.

Gestão democrática na Universidade Tecnológica Federal do Paraná

This article is the result of one ampler researching project that discusses about the limits and possibilities of the democratic management at Federal Technological University of Paraná (UTFPR). The main purpose of this text is to demonstrate that the elections to the choosing of directors of campus, recently presented, and the structuring and functioning of the collegiate counsels with deliberative forces of this institution, are elements that contribute to a relative democratization in the form of management of UTFPR.

Atitudes sociais de professoras de um município de médio porte do Paraná em relação à inclusão

The social attitudes of teachers are considered highly relevant variables in the process of construction of school inclusion. The aim of the study was to describe the elementary school teachers’ social attitudes towards the inclusion and to identify the variables related to them. The sample consisted of 172 female teachers with ages ranging from 18 to 57, mean age of 37 and standard deviation of 7,9 years of age. A questionnaire was used to describe the participants. A Likert Scale of social attitudes towards inclusion was used. The results show that the chronological age, the level of basic training, the area of specialization, and the time of teaching experience have no significant effect on the social attitudes. The teachers with experience in teaching disabled students were more favorable towards the inclusion than those without such experience. It was concluded that the social attitudes towards inclusion may be complexly determined by different variables, demanding further studies for its enlightenment.

Taxonomia molecular e filogeografia de Hypostomus strigaticeps (Teleostei: loricariidae) na bacia do alto rio Paraná

Buscando identificar marcadores populacionais que indiquem supostos mecanismos de isolamento entre as populações, no presente trabalho foram realizadas análises filogenéticas e filogeográficas em populações de Hypostomus strigaticeps, com base em sequências de DNA mitocondrial do gene ATPase 8/6. Um total de 32 exemplares provenientes de 11 populações de quatro sub-bacias: rio Mogi-Guaçu (duas), rio Paranapanema (cinco), rio Tietê (três) e Rio do Peixe (um), tiveram DNA extraído e o gene ATPase 8/6 completamente amplificado (840 pares de base) e sequenciado. As sequências obtidas foram alinhadas com o programa Bioedit, as análises filogenéticas foram realizadas no programa MEGA 5.0 através do método de Neighbor-Joining, Máxima Parcimônia e Minimun-Evolution, com 1000 réplicas de boostrap. Para as análises filogeográficas as sequências foram analisadas no programa TCS. As análises filogenéticas mostraram que a espécie forma uma unidade monofilética composta por duas linhagens: “TG” com representantes das populações dos rios Tietê, Mogi-Guaçu e Rio do Peixe, e “PC” com representantes dos rios Paranapanema e reservatório de Chavantes. A divergência genética da linhagem “TG” é de 0,1% e da linhagem “PP” é de 0,2%, enquanto a divergência genética entre as duas linhagens é de cerca de 1%. Na análise filogeográfica observou-se a existência de seis haplótipos (A-H), sendo o haplótipo A considerado ancestral para as populações analisadas. Apenas os representantes da bacia do Tietê possuem o haplótipo ancestral. Os haplótipos A, B e F possuem a maior frequência (18,51%). Os resultados obtidos para uma população do Mogi-guaçu (Cachoeira de Emas), mostram que estes peixes são muito distantes das demais populações de H. strigaticeps, tanto no ponto de vista filogenético quanto no ponto de vista fitogeográfico...

Variabilidade genética e filogeografia de populações de Prochilodus lineatus (Pisces: prochilodontidae) das bacias dos rios Paraguai-Paraná e da bacia Amazônica: bases para programas de conservação e de psicultura

A espécie Prochilodus lineatus, considerada um migrador por excelência, possui intensa ocorrência durante a migração reprodutiva. São peixes de elevado valor econômico e a sua adaptação em cativeiro os tornam altamente interessantes para desenvolvimento de programas de piscicultura. O monitoramento regular das variações genéticas nos estoques é importante em programas de conservação, evitando o declínio da variabilidade genética, essencial para a conservação das espécies. No entanto, os poucos dados moleculares populacionais para Prochilodus lineatus justificam a presente proposta. Nesse sentido, tivemos como objetivo caracterizar a variabilidade genética e estabelecer as relações filogeográficas entre 6 populações de P. lineatus das bacias dos rios Paraguai (2 do rio Paraguai e 3 do rio Cuiabá, MT) e Paraná (1 do rio Mogi-Guaçu, SP), num total de 34 indivíduos. Outros 16 indivíduos dos rios: da Prata, Uruguai, Paraná, Bermejo, Paraguai, Amazonas e Madeira, cujas sequências foram obtidas do National Center for Biotechnology Information (Genbank), foram analisados, totalizando assim, 50 indivíduos. Como grupo externo foi utilizado Salminus brasiliensis. O estudo foi realizado através das análises das sequências do gene mitocondrial ATPase 8/6. O interesse do uso de um gene mitocondrial está na vasta literatura que esse possui em análises filogenéticas e na confiança que existe nos dados gerados de tais análises. O gene citado foi completamente sequenciado (842pb), as análises filogenéticas foram conduzidas pelos métodos “Neighbor Joining (NJ)”, “Minimum Evolution (ME)” e “Máxima Parcimônia (MP)”, com 1000 réplicas de bootstrap no programa MEGA 5.0. Para análises filogeográficas as sequências foram analisadas no programa TCS e no programa Arlequin. Os resultados auxiliarão em uma melhor compreensão da história evolutiva, migração...

Litofácies e relações estratigráficas da formação Aquidauana no nordeste da Bacia do Paraná - São Sebastião do Paraíso (MG)

The Aquidauana Formation is characterized by sandstones of variable granulation, mudstones and diamectites abundant in clay, typical colors like brick red (vermelho tijolo) of glacial, fluvial and lacustrine origin. It’s chronostratigraphic equivalent to the Itarará group from the Neo Carboniferous age, that under the exploratory view, such units represent important intervals in the basin, occurring together with them minerals as well as energy resources as petroleum, underground water and coal – what requires a great paleogeography and stratigraphy knowledge for its exploration. By gathering information from the columnar sections of the area, it was possible to characterize the sedimentary facies, the stacking pattern as well as the association. It was also made an attempt of stratigraphic correlation, which showed great difficulties since glacial environments present a great lateral discontinuity of the facies besides the complex relationship process of formation. As a result, it was obtained 8 sedimentary facies, the lateral and vertical relations and genesis process. It is proposed that the sedimentary environment in the study area is the fluvio glacial, characterized by alluvial systems formed by defrosted water which transport the sediments that are deposited in plains in front of the glacier (distal outwash). Petrographic thin section analysis showed that the transportation process was ineffective. The grains present punctual to lobular contacts, characterizing good porosity and permeability to the rock, varying these qualities according to more or less existence of matrix. The presence of Iron Oxide deposited between the recrystallization border and feldspathic mineral indicates that this rock has possibly presented a primary rubefaction, intensified by alkaline fluid percolation

Análise de microclima e cobertura de dossel em áreas refloestadas nas estações de chuva e seca no Reservatório de Capivara, Paraná

O estudo das analises microclimáticas foi desenvolvido no Laboratório de Biodiversidade e Restauração de Ecossistemas da Universidade Estadual de Londrina, Paraná, e foramselecionados cinco talhões de reflorestamento de diferentes idades ao longo do Reservatório de Capivara, Paraná. Em cada talhãoforam registrados dados de temperatura, umidade do ar e cobertura de dossel,nos meses de março e agosto, período de chuva (verão) e de seca (inverno), respectivamente.Os dados foram comparados em busca de uma relação entre cobertura de dossel e microclima nos talhões de diferentes idades e nas diferentes estações. As amostragens demonstram que há uma diferença significativa entre as estações considerando as variáveis estudadas e que as variações estruturais do reflorestamento e a arquitetura das diferentes espécies que a compõem resultam em variações na cobertura do dossel, que por sua vez implicam em variações microclimáticas importantes para o processo de regeneração

Análise de dados pedogeoquímicos de multielementos visando o refinamento de mapeamento geológico de detalhe em alvos de Pb-Zn nos municípios de Adrianópolis, Cerro Azul e Tunas do Paraná (Vale do Ribeira, PR)

In order to to research, the region of Perau, base metal mineralization, Grupo Votorantim Metals conducted a soil sampling on targets predetermined holding its chemical analysis. These reviews have been provided by the company for this work was to evaluate the potential use of these data pedogeochemical multi-element for refinement of the work of geological mapping. We selected six targets: Varginha, Salvador, Guararema Taquara Lisa and Coffin of Mendes, in the municipalities of Adrianople, Cerro Azul and Tunas do Paraná, located in Vale do Ribeira (PR). Both have about 10 km2 and situated in the geological context of the Fold Belt Terrane and the Massif de Joinville. The main rock types are present metasedimentary rocks of low to medium grade metamorphic, interspersed the amphibolites ortoderivados, both belonging to the Complex Perau, gneisses and migmatitic Complex. Applied to the geochemical data descriptive statistical techniques (variogram, kriging and histogram). From the correlation between the distributions of elements with the geological data, we could assess the potential of the proposed methodology.

Proposta de traçado de alcoolduto ligando a hidrovia Tietê Paraná à refinaria do planalto paulista com uso de avaliação multicritérios e geotecnologias

From the beginning of the century, with the advent of the flex fuel car, successor fluctuations in oil prices and the rise of awareness of the impending shortage of fossil fuels, the alcohol sector begins to reappear in the panorama of national economy making Brasill reaches the point of becoming a leading exporter of this product. Ethanol assumed the role of such importance in Brazilian exports, which Petrobras through the Growth Acceleration Program (PAC) has made investments in the Brazilian pipeline network to better ensure the production of ethanol to major ports. The means of transport in pipelines are safe and inexpensive, but require careful evaluation in its implementation, they may lead to negative social and environmental impacts. Thus, the purpose of this project is to propose the best route for an ethanol pipeline connectin the Tietê-Paraná, leaving the municipality of Santa Maria da Serra (SP), to the Planalto Paulista Refinery (REPLAN), located in Paulinia (SP), belonging to the passage of ethanol export corridor, currently under revelopment. The technique used for the development of the stroke is the association of multicriteria evaluation, the geographical information system (SIG) and geotechnologies. This study presented three possible layouts for the ethanol pipeline, highlighting the best option, in addition, demonstrated the suitability of the area to receive projects of similar nature to a pipeline

Assembleias fitoplanctônicas no gradiente longitudinal barragem-jusante do reservatório de Itaipu, rio Paraná (Brasil/Paraguai)

The freshwater phytoplankton, responsible for a significant part of primary production in rivers and lakes, is of great importance for matter and energy available to other trophic levels of structuring aquatic food chains. In recent decades, the construction of dams, especially for the generation of electricity, produced changes not only in physical and chemical characteristics of rivers, but also in biocoenosis of these ecosystems. Thus, research is needed to expand the basic knowledge about these environments and subsidize actions appropriate conservation and management. Considering that lotic environments are relatively little studied, and the river-reservoir interaction, the work aims to analyze the limnological conditions and assemblies phytoplankton along the gradient established by the Itaipu reservoir and downstream stretch of the Paraná River. During two periods of the year, winter and summer, we analyzed nine sampling stations: one in lentic environment (the dam), six on the Parana River (each 5 km), at the mouth of a river Monday and another at the mouth of the Iguazu river. The phytoplankton community was composed of 315 taxa, with the class Bacillariophyceae most specious. At every point the richness was higher in summer and with a longitudinal trend in the increasing points after falling after the dam and the contribution of the tributaries. The number of taxa common to the three rivers was low in both study periods. The higher taxa can be explained by the variety of environments sampled, different residence times of water and nutrient concentrations, whereas the rivers Iguazu and Monday suffer high human influence. The greater abundance of organisms in the dam, in both periods, it should be the class Cryptophyceae contributing over 75% of total phytoplankton in point.
