With the accelerated urbanization process of Brazil from the 50s, there was a disorderly occupation of spaces and consequent soil sealing. Unlike this growth, the support capacity of urban environments has not evolved in the same way, generating negative environmental impacts to the citizens. Among these impacts are the effects of flooding. In order to minimize the negative effects of extreme precipitation over cities, the government invests in corrective measures, like compensatory techniques on urban drainage, which have as a basic principle the retention and infiltration of the rainfall, dampening the peak flow and runoff. An example of applying these techniques in urban areas are the detention basins, commonly called large pools. The hydraulic design of these structures is dependent of complex data and variables, and projects involving small areas generally use simplified methods for defining the reservoirs volume of the storage (Tassi, 2005). One of these methods is presented in this study, which relates to the percentage of soil sealing to the specific storage volume (m³/ha) in combination by applying the hydrological model of the Rational Method and analyzing regional rainfall and soil occupation over the basin. Within this context, the basin of the Wenzel stream, which is located amidst the urban area of Rio Claro/SP, also presents the problems related to human occupation in its valley. Thus, by the method presented has been adjusted a curve correlating the percentage of impermeable area and the specific volume of a detention basin. For the current situation of Wenzel Basin with 82% of impermeable area, and return period of 10 years, the specific volume is 262.1 m³/ha. The presented method is consistent with the results of other studies in the area, and the expression obtained allows estimating the volume of storage required to match hydrograph pre and post-occupancy. It presents itself as a useful tool in the planning stage of...

Swamp forests, are laid down in the lowlands, with almost permanent presence of water on the soil surface and generally occupy portions fairly flat. In 2003 a phytosociological survey was conducted of the tree and shrub component of a swamp forest established on a steep slope in Rio Claro - SP, through the use of 45 permanent plots of 10 mx 10 m (0.45 ha) divided into three blocks: 1, 2 and 3. The present study aimed to review these plots and discuss the dynamics of vegetation in the swamp forest in question period of eight years. Altogether 1529 individuals were found alive, belonging to 29 families and 47 species. It can be observed that there was a decrease of one family (Flacourtiaceae) and two species (Xylosma tweediana, Inga marginata) in relation to 2003. In general there was a loss not only in number of individuals, but basal area and species diversity. The Block 1 was the only one to show a positive balance in terms of numbers of individuals (2.75%); in Block 2, there was little variation (1.72%) which is negative; whereas Block 3 had the largest decrease, 19.18%. The mortality rate (2.74% / year) for the community remained higher than the recruitment (1.81% / year). There was a decrease (3.19%) of total basal area of the sample relative to 2003, with the highest relative dominance by Calophyllum brasiliense. The decline in diversity of species could be evidenced by the Shannon index, which was 2.0 nats.individual-1 and evenness of 0.52. The most important species (IVI) were Euterpe edulis, Calophyllum brasiliense and Magnolia ovata, together accounting for 59% of IVI community. High mortality and low recruitment rates indicate disturbances in the community, some factors such as proximity to roads, the different soil types associated with a high rate of water saturation and the declivity are crucial to the balance within the community

A number of 170 individuals of the species Pimelodus maculatus, a Neotropical fish known as mandi was collected in three distinct locations of the Piracicaba river (Piracicaba, Santa Maria da Serra and Americana – SP0 from April 2009 to February 2010. A common species of catfish whose individuals exist in many neotropical basins was observed to get more information about a possible influence of the water conditions in distant parts of a same river to its condition and also to verify whether the stomach contents of fish collected in these distinct places may distinguish as a possible consequence of food availability. The species were studied by collecting biological data such as standard length (SL) in cm, their total weights (TW ) in grams and sexes to see the composition of fish present in the samples. Length-weight relationships are important means to investigate facts related to the condition of the species in these systems. The analysis was made by using covariance to observe if individuals of similar lengths collected in distinct places may be compared to this purpose. Usual methods to investigate relationships of stomach food contents were applied. By analyzing the condition factor, one may conclude that the mandis collected in the region of Santa Maria da Serra presented similar characteristics to those obtained in Piracicaba, but they differ in this aspect for individuals collected in Americana. This fact is not conclusive about the reasons of this situation, but it may be a first step to other studies in order to get more information about. The degree of stomach repletion may be a first approach to this possible explanation, as individuals of Piracicaba presented usually full stomachs and differed in this way to individuals collected in the two other places

The research aims to propose grants for development of Municipal Plan for the Management of Organic Solid Waste generated in the municipality of Rio Claro. The research universe was composed of organic waste generators establishments (markets and grocers). From the registry of commercial establishments provided by the municipal government were identified who presented this typology, which totaled 38 establishments. In this universe the interview was conducted in 15 establishments obtained by directed sampling based on the characteristics of size, type and location. The data collected were the amount generated, disposal of waste, waste separation, collection frequency, reasons for the disposal of waste, frequency of purchase of products. From the data obtained in the field, we estimated the total generation of organic waste in this segment for the municipality. Then, the estimated costs for implementation and operation of a composting center, a way to subsidize the implementation of the management plan was carried out. We opted for the aerobic composting process by the simplicity of operation and because it is a technique already known. The average waste generation was established by tracks (size) with: stores up to 4 boxes (classified as small) generate on average 1511 kg / month, 40% of organic waste, the 5-9 boxes (small/midsize) generate on average 4338 kg / month, 35% organic and the 10 to 19 boxes (midsize) generate on average 7647 kg / month with 32% organic. In total establishments generate 105 t/ month of waste, with 35t / month of organics. 94% of establishments are in font segregation of waste into recyclable, organic and waste, indicating that the proposed management of organic waste is amenable to application without many changes in existing routine in stores. Recyclables are sent for recycling through selective collection held by the cooperative, while the organics are destined for the landfill and feed. The results indicate...

O presente trabalho teve por objetivo analisar e quantificar o banco de plântulas em trechos de Mata Ciliar do Rio Moji-Guaçu situados na Academia da Força Aérea (AFA) em Pirassununga-SP. Os trechos definidos para a amostragem foram relacionados com as condições do entorno e com a estrutura da comunidade local. Foi realizada uma avaliação da diversidade e da dominância de guildas que se encontram presentes nesse compartimento da regeneração natural, o que forneceu informações das espécies que contribuem de forma mais expressiva para a manutenção da comunidade florestal, bem como aquelas respectivas a grupos funcionais que caracterizam as condições sucessionais da estrutura atual dos segmentos de mata analisados. Na análise dos parâmetros fitossociológicos encontrou-se um Índice de Shannon-Wiener (H’) de diversidade de 3,843 nits/ind, índice de equabilidade de Pielou (J’) de 0,84, e índice de dominância de Simpson de 0,034. A síndrome de dispersão zoocórica correspondeu a quase 60% das espécies, no trecho ciliar estudado. A classe sucessional das espécies não pioneiras recebeu maior destaque, representada por 50% das espécies amostradas, mas também as lianas ocorreram com expressão no banco de plântulas analisado. Embora os padrões aqui observados possam ser generalizados, no entanto com cautela, o presente trabalho traz resultados importantes, apesar de primários, pois medidas visando à preservação e à restauração florestal dependem, primeiramente, do conhecimento sobre as espécies com ocorrência na área, sua biologia e histórico de abrangência na paisagem

The issue of solid waste disposal and urban growth are conflictive, since the areas where old uncontrolled refuse disposal were away from the city today are incorporated to the urban area population. Thus, now population is closer to the degradation of contaminants coming from waste disposal, and, in some cases, these areas become housing subdivisions. This work aims to support the diagnosis of a former landfill in the municipality of Rio Claro (SP), using geophysical methods through resistivity anomalies. In order to develop the diagnostic, it was utilized water and soil analysis of a preliminary report and techniques of vertical electrical sounding and electrical profiling. The areas influenced by the garbage presented less resistivity than the one of the natural subsoil. Through the interpretation of results, the local potentiometric map was elaborated, as well as a map of calculated resistivity. The interpretation of these products indicated a disagreement between the groundwater flow and the current topography, leading to an identification of a preferential direction of the contamination plume in the NE-SW. These observations prove the applicability of geoelectrical methods in areas of former waste disposal with little information.

Introduction: Given the repercussion of the important role of physical activity in the prevention of sickness and non-communicable diseases / loss, many works have been done in order to understand the association of sociodemographic characteristics with sedentarism. The elements which influence the physical activity practice are countless. Besides the intrapersonal element, environment elements (social environment, cultural environment, public politics, information environment, natural environment etc.) are also important in the life style. Yet, the way that the person understands the environment can be considered in the planning of the strategies to change the sedentary behavior. Objective: Verify the association of the environment perception with the practice of physical activity (FA) at leisure time in adults living in Rio Claro – SP. Methodology: The sample consists of 470 adults, all residente in rio Claro-SP, aged ≥ 18 years old. The chosen participants answered to the questionnaires: Neighborhood Environmental Walkability Scale (NEWS), International Physical Activity (IPAQ) and to a specific questionnaire with personal data (age, sex, educational level, economical level, weight, height and marital status). The analysis of the connection between the variables was done through the Logistic Regression with Confidence Interval of 95%, using the software SPSS 17.0. Those who reached the recommendation of 10 minutes or more of physical activity in leisure time for week were classified as active, and those who did not reach the recommendation were classified as underactive. Results: The proportion of subjects who practiced physical activity in leisure time was 38,7%, and the male subjects, as well as those classified as better social level showed higher chances to practice at least 10 minutes weekly of physical activity during leisure. Still, walking the dog, soccer fields and gardens near the house (less than 10 walking minutes), were...

Cerca de um terço do total de doenças em adultos estão associadas a condições ou comportamentos que começaram na juventude. No Brasil, a porcentagem de Inatividade Física (IF) nos adolescentes varia entre 29% a 94%, que é um dado alarmante, pois esses adolescentes provavelmente serão adultos inativos fisicamente e com um risco maior de adquirirem uma doença de agravo não transmissível. Desse modo, o objetivo do estudo foi verificar a prevalência e os fatores associados à IF em escolares do Ensino Médio do município de Rio Claro- SP. Estudo do tipo transversal, de base populacional, realizado no primeiro semestre letivo de 2009 contou com a participação de 467 alunos (213 homens e 254 mulheres) das escolas particulares e estaduais do Ensino Médio do município de Rio Claro-SP. Para avaliar o de nível de Atividade Física (AF) dos adolescentes foi utilizado o Physical Activity Questionnarie-Children (PAQ-C). Foi aferido a circunferência de abdômen e calculado o Índice de Massa Corpórea (IMC). Os pais responderam um questionário para avaliar o nível de AF através do International Physical Activity Questionnarie (IPAQ) e o nível socioeconômico. Para verificar a associação entre as variáveis (sexo, nível socioeconômico, IMC e circunferência de abdômen) com o nível de AF dos adolescentes foi realizado a Regressão Logística e para verificar a associação entre o nível de AF dos adolescentes e dos pais foi realizado o Teste Qui-Quadrado. A prevalência de IF dos adolescentes foi de aproximadamente 83% e, dentre as variáveis analisadas, apenas sexo mostrou-se significante (p=0,00), sendo o sexo feminino com maior chance de IF.

Laboratory of Chemical Waste Management programs are being implemented in various universities of the country and the world, in recognition of the urgent need to change the reality of disregard for the environment, together with objective responsibility of the generator, and especially the awareness of sustainability. Analysis and research laboratories involve a range of waste in developing their studies with intrinsic characteristics related to their form of generation. The amount of waste generated in this segment is negligible compared to industrial activities, but the environmental issue is that these residues do not have a standard technique for treatment due to the potential variation of its composition. This research project, aiming their suitability and continuous improvement, aims to diagnose and analyze the current situation of the management and disposal of chemical waste generated by the laboratories IGCE UNESP, Campus Rio Claro / SP. Universities, through their research, teaching and extension, end up generating potentially hazardous chemicals that may contaminate the environment when they are disposed of improperly, with no concern for the environment and / or public health. Aiming to assist in improvements with respect to this issue, the purpose of this study is to understand the management and disposal of chemical waste from the IGCE, laboratories UNESP - Rio Claro / SP, in order to discuss the situation of such waste, and present proposals to reduce generation of the same and minimizing the environmental impact, thereby increasing the local hygiene through proper disposal. The research instrument used interviews, questionnaires, review of recent literature and observations were made in order to develop proposals for the management and disposal of waste. These proposals based on prevention and corrective control, where the preventive approach aims at lifting techniques and actions to reduce the generating sources and...

The Urbanization is a notable process in our society, being part of it since around 3500 BC in Mesopotamia, currently Iraq area. Since the Industrial Revolution, cities had a significant increase in their growth and began to concentrate increasingly labor and capital. Brazil, despite having had a late industrialization, also had a high population growth in cities, especially in the XVIII century, which were not provided with any kind of planning that targets the ordering and implementation of the urban essential apparatus. Therefore, Brazilian cities started to exhibit countless structural and environmental problems. Associated with inadequate infrastructure, the modifications in the urban atmosphere, like increased heat, air pollution and increased rainfall and storm frequency, cause different types of impacts in cities. Among the most worrisome are those from the intense rain, which cause human and material damage. The city of Rio Claro (SP) can be considered an example of this reality. Thereby, the objective of this study was to analyze the impacts on the population originated from rainfall in the urban area during the period 2005-2010, by the mapping of events and analysis of the active atmospheric systems. The information of the events were collected in the Fire Department and the Press and the synoptic maps were obtained in the library of INPE, in Cachoeira Paulista (SP) and in the site of the Navy of Brazil. The data showed that among 247 occurrences, during the six years, 233 occurred in the spring-summer period. Moreover, after finalizing the maps, it was found the locations considered critical regarding the frequency of occurrences, as: Visconde do Rio Claro Avenue and central area of the city, both with a total of 23 occurrences; Jardim Inocoop, with 20; Tancredo Neves Avenue, with 12 and Vila Paulista, with 10 occurrences. Through the graphs, it was found that the most recurrent atmospheric system, during the studied period, is...

Diante do desenfreado uso da terra, gerando impactos muitas vezes irreversíveis, o planejamento ambiental insere-se como uma ferramenta atualmente necessária. Visto que é sob o relevo que se consolidam as atividades antrópicas, a cartografia do relevo surge como um importante instrumento, indicando setores cujas características naturais impõem limites ao uso da terra. Assim, o objetivo desta pesquisa é analisar as características geomorfológicas da alta bacia do Rio Itanhaém, com ênfase à questão morfográfica e morfométrica do relevo, avaliando também as modificações impostas a este em decorrência do uso da terra, contribuindo, portanto, com a gestão ambiental desta área. Para tanto, foram elaborados documentos cartográficos capazes de evidenciar as características do relevo que impõem limites ao uso antrópico, a saber: as cartas morfométricas (carta de declividade, carta de dissecação vertical, carta de dissecação horizontal e carta de energia do relevo), que são documentos que evidenciam a suscetibilidade potencial do relevo sob a influência da ação das águas e gravitacional; a carta geomorfológica (cenário de 1962), que possibilita a espacialização das formas do relevo, contribuindo para a análise da morfodinâmica; e as cartas de uso da terra (cenário de 1962 e 2000), que, em conjunto com os documentos já especificados, possibilitam a análise da influência da atuação antrópica sob o sistema relevo. De maneira geral, pôde-se detectar problemas na morfodinâmica da área de estudo, evidenciados pela presença de feições denudacionais localizadas, tais como sulcos erosivos, voçorocas, ravina e cicatrizes de escorregamentos, os quais vinculam-se ao potencial natural que o relevo da área de estudo possui ao desencadeamento de processos morfogenéticos; à dinamização de processos naturais pela atuação antrópica...
