Variação linguística e ensino

This monograph analyzes, based on the collected data, some aspects of the teaching of the linguistic variation in schools: if the linguistic studies have been incorporated in teaching in some way in order to promote a less conservative and prejudiced perception of language, providing students the opportunity to recognize the different language varieties and judge the situations in which each of them is the most appropriate one

Análise da variação da vazão e da concentração do metano presentes nos gases gerados no aterro sanitário de Rio Claro - SP

The study of the generation of landfill gas contributes to the understanding of the relationship between gas production and other parameters, such as time of disposal of waste and moisture (rainfall) and, thus, can subsidize the viability study for energy. This study aims to evaluate the interference of the time of disposal of waste and moisture (rainfall) in the production and composition of biogas generated at the landfill in Rio Claro - SP. As a result it was observed that for the landfill studied, the average percentage of methane in biogas ranged from 49.9% to 54.7%. It was found that moisture (rainfall) and the time of waste disposal are parameters which do not cause significant changes in methane concentration in biogas. However, when analyzed the flow of biogas, which had the maximum average value of 152.86m3/h and minimum average value of 15.47m3/h was observed great interference of moisture (rainfall) and the time of disposal of waste, because well of gas located in newer areas of the landfill showed higher values of flow rate than the areas where the landfill was the beginning of the arrangement. The same way, it was observed that in the dry season flow of biogas decreased in all drains gas analyzed

Variação fenotípica nas espécies de Rhinella do grupo crucifer (Anura: bufonidae) na Mata Atlântica do Brasil

A Mata Atlântica Brasileira apresenta ampla distribuição e diferenças regionais na composição de suas paisagens, favorecendo alta diversidade e endemismo. O grupo de espécies de Rhinella crucifer é endêmico a este bioma, e distribui-se através de todo seu domínio. O grupo é composto por cinco morfoespécies, definidas com o auxilio da morfometria tradicional. Recentemente foi encontrado que apenas três destas morfoespécies correspondem a linhagens genéticas exclusivas. Neste trabalho é proposta uma releitura da variação fenotípica das espécies de Rhinella do grupo crucifer com base na morfometria geométrica, uma técnica moderna capaz de detectar padrões de variação mais refinados. Tanto em análise realizada com peso igual para variações de forma globais e locais, quanto em análise que valoriza apenas variações localizadas houve a formação de dois grupos; um contendo morfoespécie Rhinella henseli e outro formado pelo restante das morfoespécies. A alta sobreposição encontrada neste segundo grupo evidencia grande semelhança na forma craniana, sendo R henseli a morfoespécie mais diferente do grupo. Este resultado é condizente com os achados genéticos recentes, podendo- se concluir que a variação fenotípica no grupo é acompanhada pela a variação genética. Um estudo futuro com amostragem mais representativa e aprimoramento na metodologia poderá contribuir para uma melhor compreensão da diversificação morfológica nesse grupo de espécies em escala mais fina.

Estudo da variação da porcentagem e da estimativa de geração de gás metano para o aterro sanitário do município de Rio Claro - SP

Increased demand for energy and the search for alternative energy sources are remarkable and current facts. The management of domestic solid waste is also part of the issue in view of the possibility of power generation in existing landfills, which could provide financial autonomy to the system of waste management and improve the environmental balance of landfills in Brazil, currently only used for final solids disposal. Landfill gas is a viable alternative energy source has been tested in landfills in the World and in Brazil. Thus, the research aimed to evaluate the percentage of methane (CH4) present in three sinks of gases from a landfill in the municipality of Rio Claro – SP (Brazil), and to estimate the potential methane generation over its life through the application of a mathematical model. As a result it was found that in general the percentage of methane present in the gases is significant, between 50 and 62%. It was also noted that waste with disposal time between 8 and 12 months already are in the methanogenic stage. Finally, there was a tendency to increase the generation of methane in the transition periods of rain and drought

Variação na curva de crescimento e tamanho de asa de Zaprionus indianus (Gupta, 1970) (Diptera: Drosophilidae) de acordo com diferentes temperaturas

Insetos são estudados como modelos biológicos e evolutivos devido, principalmente, ao tamanho reduzido e ciclo de vida curto, tendo importância ecológica pelo fato de gerarem diversos benefícios em todos os ecossistemas e estarem presentes em todos os níveis tróficos. A espécie Zaprionus indianus pertence à família Drosophilidae, é nativa da África Tropical e foi recentemente introduzida no Brasil, causando grande preocupação devido aos danos causados na produção de figo roxo (Ficus carica). A temperatura é um dos fatores abióticos que influencia a velocidade de desenvolvimento, fecundidade e dispersão dos insetos, provocando alterações em aspectos morfológicos e relativos ao ciclo de vida de drosofilídeos. Estudos sobre a influência da temperatura no desenvolvimento de Z. indianus são importantes para um futuro programa de controle dessa praga, de acordo com as características climáticas de cada região. Este trabalho teve como objetivo avaliar o efeito de diferentes temperaturas, em diferentes densidades larvais, sobre a espécie Z. indianus, visando analisar sua curva de crescimento e tamanho de asa. Adultos de Z. indianus foram coletados nas dependências da Universidade Estadual Paulista (Rio Claro - SP), com auxílio de puçá entomológico. Da amostra de drosofilídeos coletados, os espécimes de Z. indianus foram identificados e mantidos em potes plásticos redondos, estes acondicionados em câmaras climáticas sob condições controladas de temperatura e umidade e fotoperíodo. Foi oferecida como alimento dieta artificial comum de drosofilídeos feita à base de banana. Os ovos obtidos foram contados e separados em densidades de 100 e 500 indivíduos, em duplicata para cada densidade e temperatura testadas; os imaturos foram mantidos sob as mesmas condições que os parentais, exceto pela temperatura que foi estipulada de forma a se estudar os efeitos de três...

Determinação da crítica razão esforço-pausa em Uchi-Komi no judô, com a utilização de deltas de variação de lactato sanguíneo e da escala subjetiva de esforço de Borg

In the competitive judo, the form as a trainer organizes the process of his/her athlete's training is a very important task for a good acting and a better use of the technical procedures. There is great importance in determining the exercise intensity for the judocas training due to the interest for the high income in several competitions, and few studies returned for this research area, involving those athletes' different physiologic conditions. Therefore, it is necessary to improve protocols of physical evaluation for this modality, increasing his/her applicability. The present study aimed at to verify the validity of a protocol of specific aerobic test of the judo (technique ipon-seoi-nague), no exhausting, adapted of the method of CHASSAIN (1986), using deltas of variations of the lactacidemia and of the Scale of Perception of Effort of Borg, in athletes well. The test adapted to the judo constituted of four exercise series with two efforts similar (double) of 180 seconds with one interval of 90 seconds among them. The series of exercises were accomplished in consecutive days. The intensities of the double tests were of 85%, 95%, 105% and 115% of the minimum lactato for each participant. This work used the technique ipon-seoi-nague, obeying the reasons effort-pause individualized for each athlete, that you/they correspond to the intensities of exercises proposed by the protocol of CHASSAIN (1986). In that way, the athletes applied a blow (maximum speed) and they rested some seconds, depending on the regime effort-pause of the session. At the end of each collection collection of blood (25NL) of each participant's earlobe was accomplished, seeking to measure the concentration of sanguine lactato. The collections were accomplished at the end of the first and of the second efforts, in each one of the series. For the analysis of the Perception of the athletes' Effort, the Scale of Perception...

Reação à variação ambiental em lebistes: o sexo importa?

Aqui mostramos que lebistes percebem modificações estruturais ambientais, mas que reagem a elas diferentemente quanto ao sexo. Vimos também que essas reações associam-se aos traços de personalidade de ousadia e hesitação. Os machos se locomoveram mais que as fêmeas e interagiram mais com objetos familiares. Porém, a introdução de objeto novo aumentou a interação das fêmeas com os objetos familiares. Além disso, machos e fêmeas interagiram mais com objeto familiar estruturalmente mais complexo comparado ao mais simples. No conjunto, esses dados indicam um perfil mais ousado dos machos e um perfil hesitante das fêmeas. Em todos os casos, as diferentes respostas de machos e fêmeas foram explicadas num contexto evolutivo adaptativo

Variação histórica dos preços e das reservas de petróleo brasileiras e internacionais no período 1992-2011

The oil market is not a common market, and its complexity increases dramatically when considering the strategic and geopolitical involved, thus resulting in large uncertainties and concerns. The attempt to control prices has always been a challenge for the major world powers, since the increase in oil prices benefits the exporting countries, but harms importers, especially those regarded as less developed. Understand and try to predict some strategies adopted up the oil crises is one of the main points of the research, in order to demonstrate how economics can be used as an instrument of power and domination between nations, and how plans and strategies and rearrangements of supply and demand favor the growth of this economy, especially in the current period, with the new Brazilian oil era, beginning with the discovery of pre-salt, amid a context of growing need for the use of oil and its derivatives

Análise da percepção da variação do campo térmico na cidade de São Paulo-SP: o exemplo da subprefeitura Sé

This research aimed to analyze the spatial area for the design of the Heat Island of Subprefecture Sé, in São Paulo-SP, with the support of geotecnology and based on the study of environmental perception. We used remote sensing products such as maps ofland use and soil temperature and apparent surface to evaluate the thermal conditions considered critical points in the central area of the municipality. The methodology used was qualitative analysis, based on interviews with the people, allowing rescue geoecology the conditioning aspects of the city, with an emphasis on environmental perception. This study aimed toanalyze the perception of the variation of the thermal field in São Paulo. The results indicated that (95%) of respondents feel that the temperature of the central area has increased each year, and the district that stood out was the Sé, due to intense use and occupation of land and contribute one of the largest shopping centers. Districts with points given for having better thermal comfort were Santa Cecília, the República and Bela Vista, due to their larger amount of green areas by fiscal court, which act as local refrigerators. It was found that the respondents have the perception and awareness of their spa directly related to the quality of life. Through analysis of several variables involved, proposals and strategies may support public policies and urban planning

Moçada, moçaiada, moçarada: um caso de variação?

Com base nos estudos sociolingüísticos e nos processos de formação de palavras através da sufixação, este estudo analisa algumas formações de palavras a partir dos sufixos -ADA, -ARADA e -AIADA. A pesquisa volta-se para as construções que indicam “grande quantidade”. Pretende-se relacionar o uso destes sufixos com o grau de escolaridade do falante e o contexto de uso, para, na medida do possível, analisar se estes dois fatores podem influenciar um maior ou menor uso destas palavras. Para isso utilizou-se dados provenientes da internet, assim como os resultados de dois testes de percepção aplicados em alguns colaboradores de graus de escolaridade distintos. A partir da análise dos dados obtidos na internet e nos testes, constatou-se que os sufixos -ADA, -ARADA e -AIADA, principalmente estes, estão sendo usado amplamente em conversações mais informais, sendo que nos testes, os colaboradores com maior nível de escolaridade foram os que se mostraram mais conservadores em relação às construções. Para alguns dos entrevistados, o uso das palavras formadas com os sufixos em estudo deve ser restrito a situações bastante informais, sendo “inadequado” seu uso numa situação formal

A variação sócio-cultural e o ensino de língua portuguesa no ensino fundamental: por uma pedagogia sensivelmente cultural

This study aimed to gather information about the social and linguistic reality of students 1. years of elementary school and community that came, in order to identify aspects of their lexical phonological levels, morphological and morphosyntactic and thus identify and describe the alternative variants of non-standard rule. The methodology chosen was that of variational sociolinguistics addressing quantitative and qualitative aspects in the treatment of the data collected through participant observation and audio recordings of speeches of the students. The results indicate that the level of phonological variants are the most frequent in the speech of students. Because the literacy phase, how the student speaks serves you a guide to the act of writing, so it is necessary to work with the students the difference between oral and written form and monitoring of these two modes according to the context of the discourse

Efeitos da variação do teor de umidade da madeira no processo de lixamento

The process of sanding wood is little known and industries use it in a practical way without having studied their best conditions before. There are few studies involving this type of machining. On this basis, this paper studied the effects of varying moisture content of the wood surface quality after the sanding process. It was used a sanding machine with flat horizontal cut parallel to the fibers, using: 02 different species (Pinus elliottii and Corymbia citriodora); 01 sanding abrasive (aluminum oxide) and 03 different particle size abrasives ( P80 , P100 and P120 ) . Initially, the pieces were acclimatized ( 2 ± 7% , 12% and 17% ± 2 ± 2 ) and subsequently passed by the sanding process, and therefore, the surface roughness was analyzed. For each condition, were performed 06 repetitions totaling 54 trials for each species. We analyzed the effects of wood moisture by capturing the power sanding, rougheness, acoustic emission and maximum temperature during the sanding process. The variation of moisture content produced changes in the surface quality of the finished parts, and these changes were more marked in Pinus than Corymbia. During the sanding process of the specimens with 7 % and 12 % humidity, there was a lower noise emission, power consumption and heating surface. When checking the roughness of these parts after this process, it was observed that the surface quality of them were superior in the parts sanded containing 17 % moisture

Estudo acústico da variação da frase interrogativa, com destaque para o dialeto paulista

With the new computational technology, the studies of acoustic phonetics started to have a special place. This brought a new way of seeing the phenomenon and to deal with it in the phonetics and in the phonology. Such studies have been developing even more, recently, with a facilitated use of computational programs specially developed to the acoustic analysis of speech, such as PRAAT. Programs like this have been very interesting and useful recently. The acoustic models of analysis have influenced the way the researchers came to see and to interpret the prosodic phenomenon. The current project investigates the acoustic production of declarative and interrogative sentences from the “paulista” Portuguese. This study contributes for a more detailed description of the phenomenon, also becoming inserted in the chart of “intonational” descriptions of the Brazilian Portuguese. The subject of this current project is the acoustic study of some intonation aspects from the speaking Portuguese in Brazil, with a special place to the “paulista” dialect. The current project´s purpose is to make a specific study of interrogatives sentences through the acoustic data analysis of “paulista” dialect speakers

Educação no campo e educação rural: distinção necessária para compreensão da realidade geográfica

The work’s objective is to point out the difference between rural / urban and country side / city, drawing on the historical process of formation of the terms and analyzing the current dichotomous and continuous, to clarify the concepts of education in rural and rural education, in an attempt to differentiate these types of education in accordance with the schools. Also works with the different conceptions of children, adolescents and youth of the rural that are mostly students from schools in the 1st and 2nd grade. On empirical evidences, we try to adapt the concepts studied in the School Municipal Agricultural Engenheiro Rubens Foot Guimarães, Rio Claro, SP
