Avaliação da auto-suficiência energética de reatores anaeróbios no tratamento de esgoto sanitário e água cinza

The anaerobic treatment of sewage is widely employed in Brazil and it is an appreciated way for the treatment of effluents, helping to reduce the environmental impact in rivers. The methane gas obtained from the process can be applied to improve the energetic efficiency of the system, reducing the amount of waste and the cost of the treatment process. This work presents the net energy balance of anaerobic reactors applied to the treatment of sewage. The analysis was performed considering full-scale and laboratory-scale treatment systems. In laboratory scale, the results from three kinds of systems were compared regarding the biological treatment of greywater. Two of them (UASB7 and UASB12) were anaerobic and the other one was a combined anaerobic-aerobic system (UASB7/SBR6). Greywater methanization (compared to theoretical maximum) was calculated considering 100% removal (g BOD/day), the literature percentage removal and the anionic surfactant presence in the effluentt. For each of these three cases, the efficiencies were, respectively, 16.9%, 43.6% and 51.3% in UASB7 reactor, 25.6%, 50.3% and 59.2% in UASB12 reactor and 30.6%, 61.2% and 71.9% in UASB7/SBR6 reactor. The energetic potential was found to be 4.66x10-4, 7.77x10-4 and 5.12x10-4 kWh/L for the UASB7, UASB12 and UASB7/SBR6 reactors, respectively. The pumping system, the aeration (in the anaerobic-aerobic system) and the temperature controlled heating system were considered to calculate the energetic consumption. However, the third one was not employed since tropical regions like Brazil do not need heating systems and also because of its high energetic consumption. The calculated net energy balance in the reactors was negative in the case of greywater, respectively -0.16, -0.28 and -0.18 kWh/L for the reactors UASB7, UASB12 and UASB7/SRB6. In full scale (ETE Jardim das Flores - Rio Claro, SP), the average energy... (Complete abstract click electronic access below)

Os conflitos escolares na Escola Estadual Joaquim Ribeiro entre os anos de 1968 e 1999

A preocupação com a problemática da violência no âmbito escolar e as relações entre seus sujeitos, despertou a necessidade de debater sua produção e reprodução. Esse projeto visa discorrer sobre os conflitos ocorridos dentro da escola pesquisada durante um determinado período histórico (1968-1999) e tem por objetivo apresentar uma síntese das discussões sobre este tema, revelando o conceito de violência e indisciplina para essa instituição de ensino e como a legislação vigente (LDB e regimentos comuns) influenciava no cotidiano de seus principais atores. Para isso, foram utilizados documentos (atas, cadernos e outros) do período de 1968 a 1999, da E.E “Joaquim Ribeiro”, no Município de Rio Claro, São Paulo. Foi empregada a metodologia qualitativa, através da análise documental e análise de conteúdo

Escola e heterogeneidade: contribuições para pensar práticas pedagógicas diferenciadas

In 2011, I had the opportunity to be inserted in two elementary schools in the city of Rio Claro - SP: a) as a researcher student, participating in the research project “Pedagogical Practice and Collective work in School: The Rescue of the Narrative and the Teacher’s Knowledge”; b) as a intern, developing the Required Stage as established in the curriculum of the Full Degree Pedagogy Course (UNESP). These two experiences have made me think about the configuration of the school and its relationship with the homogenizing practices: What are the possibilities and conditions to be taken into consideration of the multiculturalism in school? The teacher’s graduation fits the plural characteristic in the classroom? Therefore, the goal of the research is to understand the concept of the multiculturalism within the school and in the processes of teacher graduation. I intend with that, to list in which grade the school organization favors or not the practices that fit the plural characteristics of the students. For the achievement of the goal, I intend to develop a bibliographic search, from the selected articles of the ANPEd (National Association of Graduate Studies and Research in Education) in the Working Groups (GT): GT04 – Didactic, GT12 – Curriculum e GT13 – Elementary School. I have dialogued with authors who have allowed me to broaden the understanding of school organization and authors who have allowed me to look at multiculturalism both within school and in teacher graduation. And yet, in the search to know practices that fit multiculturalism in school, I did the analysis of the dissertation prepared by an elementary school teacher who went to live with a group of teens, promoting the meeting of the school culture with street culture as a strategy to rescue the humanization of students. The students are singular subjects and, therefore, the interest in knowing different works that attemp to recognize the importance of diversity

Estudo da tratabilidade de água pluvial utilizando coagulante natural a base de tanino visando fins não potáveis

This paper aimed to study the treatability of rainwater collected in Rio Claro, SP, using natural coagulant tannin based. The tannin was compared with other too primary coagulants, namely ferric chloride and corn starch. Assays were performed in laboratory scale using equipment known as Jarteste and aimed to study the conditions most suitable dosage and coagulation pH. First tests were conducted to compare the coagulating and determination of the conditions to be used in the following tests, taking as a criterion the greatest efficiency for water treatment. Also performed were performed tests to construct the tannin coagulation diagram, using the optimal concentration found in the previous phase, by varying the dosage of coagulant and the pH of clotting in order to determine the isoefficiency regions for apparent color and turbidity. Finally, tests were performed cyclically filtration with filter paper. Preliminary tests indicated that the vegetable tannin concentration 3% (m/m) from the commercial solution was presented the best set of results (84.3% removal of apparent color and 82.51% removal of turbidity) compared to ferric chloride (66.25% removal efficiency and apparent color of turbidity 67.82%) and starch (73.68% removal efficiency apparent color and turbidity to 67.19%). The coagulation diagrams indicate that the best region to work with vegetable tannin 3% is where the coagulant dosage ranges from 15 mg/L to about 37.5 mg/L and coagulation pH ranging from about 6.5 to 7.5. The cyclic filtration showed to be not efficient for the best dosage of coagulant, due to the process of clogging of the filter paper, but proved to be efficient for other dosages. Thus, for the waters studied, the results indicate that the natural coagulant based tannin is an alternative to conventional coagulants, possessing benefits of technical and environmental

População e áreas de risco: o caso das inundações na área central de São José do Rio Preto-SP

The problem of flooding in urban areas exist in many cities and their causes are as varied as the areas of occupancy or Valley weatherproofing Fund areas of infiltration in the drainage basin. The anthropic activity come triggering changes and impacts on the environment for a long time, and there is a growing need to come up with solutions and strategies that minimize and reverse the effects caused these risk areas. Thus, the present work will address the case study in São José do Rio Preto-SP that is an exception, since the area that is considered of risk lies in the Centre, unlike most lying on the outskirts. This will also analyze the processes of urban expansion and the situations of social and environmental vulnerability, including their interrelations in urban scale. The physical study of the area will serve as an important basis for the work, but it will focus mainly on the population and the problems which this is being in hazardous areas. We will not join a single methodology, wharever, we will follow our knowledge to adapt what we feel that fits better, every time. The importance of this study is that in addition to identifying the problems which the local population suffers with floods, lists measures that minimize the environmental impacts arising through the fostering of public policies

Variação inter-sexual na frequência de cromossomos Bs em Corydoras aeneus (Siluriformes: Callichthyidae)

The genus Corydoras, the highest among the Siluriformes, Callichthyidae is owned by the family, consisting of 177 valid species and widely distributed in cis-Andean portion of South America How striking feature has two longitudinal series of dermal plates covering almost the entire body. Cytogenetic studies in Callichthyidae show many chromosomal rearrangements, including events of polyploidy in their evolutionary history, particularly the genus Corydoras, in which the variation is the diploid number of 2n = 40 to 2n = 134 chromosomes. The absence of information on the frequency of chromosomes in the group Bs motivated this work with the species Corydoras aeneus. A population from the Tietê River basin in Ribeirão Claro (subbasin Corumbataí - Rio Claro, SP) was sampled a total of 20 subjects (10 males and 10 females) and 30 metaphases per individual were analyzed cytogenetically. Were carried out by impregnation techniques silver (Ag-NOR). The observed modal diploid number was 2n = 60 (26m +26 sm +8 st), with the variable occurrence of 1 or 2 Bs chromosomes in males and a B chromosome in females, both acrocentric. Regarding the variation in the frequency of chromosome Bs, the occurrence of two B chromosomes is directly linked to males, because there were no female sampled with the occurrence of two chromosomes Bs The low frequency of Bs in females suggests that this event can be sporadic this sex, different from males in which this appears to be set supernumerary chromosome showing a higher frequency of 2 Bs than the actual modal number of 2n = 60. Further studies will be performed to understand the dynamics of the B chromosome in the population

As práticas disciplinares aplicadas aos alunos da 4ª série de uma escola municipal de Rio Claro: um estudo de caso

Esta pesquisa busca identificar qual é a compreensão que alunos, professores e equipe gestora da escola tem sobre o conceito de indisciplina e, como este foi se construindo ao longo dos anos. Dessa forma mediante as observações das relações existentes dentro de uma unidade educacional do município de Rio Claro foram analisadas as práticas punitivas aplicadas para os alunos considerados indisciplinados. A indisciplina atualmente tornou-se objeto de muita preocupação devido à transformação de suas causas e efeitos na sociedade. A escola, atualmente, apresenta um número considerável de grupos que a frequentam com propósitos e ideais diferentes e isso pode motivar a criação de conflitos em que se torna necessário a mudança de atitude no tratamento desses comportamentos considerados como indisciplinados.

Estrutura populacional de Oeceoclades maculata Lindl. (Orchidaceae), em um mosaico vegetacional (FEENA) da Floresta Estadual Edmundo Navarro de Andrade, Rio Claro, São Paulo

O objetivo do presente estudo foi avaliar a estrutura de população de O. maculata, através de sua distribuição espacial e estrutura de habitat, comparando características físicas e biológicas em diferentes fisionomias de Pinus spp. e Eucalyptus spp.. Foram montadas 86 parcelas de 5m por 10m, distribuídas uniformemente entre 4 áreas pré-estabelecidas de fisionomias distintas. Os indivíduos levantados foram separados em duas classes etárias, jovens e adultos, e contabilizou-se a taxa de predação, número de pseudobulbos e número de folhas. Os parâmetros ambientais avaliados foram cobertura herbácea, densidade de dossel, luminosidade e umidade de serrapilheira. A espécie apresentou densidades bastante elevadas nas áreas de plantios de eucalipto (1224 e 1733 indivíduos por hectare) e baixas nos plantios de pinus (88 e 26 individuos por hectare) o que levou as análises a se concentrarem nas fisionomias compostas por eucaliptos. O padrão de distribuição da espécie foi o agregado em todos os ambientes. Indivíduos adultos apresentaram significativamente um número médio de pseudobulbos maior que indivíduos jovens (Mann-Whitney; U = 24248.500; p<0,001), porém a diferença no número de folhas não foi significativa. A taxa de predação foliar em O. maculata entre as áreas de eucaliptos apresentou variação significativa. A variação do total de folhas predadas foi confirmada pelo teste Qui-quadrado de Pearson (X²=115.487; gl=1; p<0.001). A comparação de médias, com base no teste de Kruskal-Wallis, para cobertura de dossel (H(3,N=102)=28,534 p<0,001) e cobertura herbácea H(3,N=94)=28,246, p<0,001, mostrou taxas menores nas áreas de eucalipto. A umidade da serrapilheira foi menor (36,5%) nos locais onde a espécie apresentou agrupamentos, quando comparada aos locais de ausência (47,5%). Oeceoclades maculata Lindl. possui grande capacidade para colonizar ambientes... (Resumo completo, clicar acesso eletrônico abaixo)

Mapeamento geoestatístico da permeabilidade superficial no entorno do Ribeirão Claro: e simulação da possibilidade de sua contaminação

The evaluation of soil permeability throughout the weathering profile is one of the most important features to be considered in environmental studies. This study, developed from field testing and analysis of data obtained by geostatistical methods, aims at mapping the permeability around the Ribeirão Claro river. The intent is to simulate an accident with toxic liquids where soil permeability is of fundamental importance. Another purpose of the research was to determine the minimum time that, in the event of an accident, a possible contaminant to reach the water table level and be routed to the nearest drain, in this case, the Ribeirao V Claro river constitutes fundamental information. The studied area of approximately 4 km² is located within the UNESP-Rio Claro campus, consisting of colluvial soil from Fm. Rio Claro superimposed on residual soil of Fm. Corumbataí. The method used to determine the permeability is the concentric cylinders performed on a sampling grid with 64 points containing spacing of 5 meters EW and 10 meters NS. In the places of permeability tests were collected samples for laboratory determination of the percentage of fines. From particle size analysis was performed and analysis statistical and geostatistical on this data. The histogram was based on the statistical studies, and the semivariograms were based on geostatistical estimation methods. Based on the comparison between the maps and the data obtained, it was determined that the percentage of fines in colluvial surface soil has little influence on permeability, which the proximity to the Ribeirao Claro river, the eastern portion, a factor that influences the distribution of permeability values
