Arte e resistência: Vincent Willem Van Gogh

Esta tese apresenta uma proposta interdisciplinar para abordar o objeto artístico, almejando demonstrar como a Psicologia pode enfocar a leitura e a interpretação das produções artísticas visuais. Foram aplicados métodos psicológicos considerados eficazes para entender o fenômeno artístico e, assim, interpretar o trabalho do artista. O instrumental teórico foi o da apreensão fenomenológica e o conhecimento psicanalítoco. Trinta e nove telas de Van Gogh (produzidas em Arles, 1888; no asilo de Saint Rémy, Provence, 1889; e em Auvers Sur Oise, 1890) foram selecionadas para análise. Foram Observados os aspectos da visualidade da obra, segundo a ótica fenomenológica, e as imagens foram investigadas em sua disposição em um espaço simbólico do espaço pessoal do artista, dos elementos configurados que compõem a foma, da iluminação e cor empregadas no trabalho e da dinâmica e expressão dos conteúdos manifestos. A tese constitui-se de quatro capítulos. O primeiro apresenta a história do artista; o segundo, a teoria para abordar a percepção fenomenológica, definindo elementos utilizados para interpretar o objeto artístico; o terceiro analisa as imagens produzidas por Van Gogh no período estudado; o quarto diagnostica, analisa e interpreta a expressão das imagens. Foi também analisada a temática explorada pelo artista, de acordo com sua manifestação simbólica. A trajetória deste trabalho assemelhase ao psicodiagnóstico, que levanta hipóteses e verifica se elas são verdadeiras ou falsas. Assim foi levantada a hipótese de que a arte atuava na existência do artista como um procedimento terapêutico e mantenedor do seu equilibrio. A maior êncase da literatura recai na loucura de Van Gogh como propulsora de sua obra, visão oposta à desta tese... (Resumo completo, clicar acesso eletrônico abaixo)

Anatomia de folhas, brácteas e escapos de Paepalanthus Sect. Diphyomene Ruhland (Eriocaulaceae, Poales)

As Eriocaulaceae brasileiras encontram-se distribuídas principalmente nos campos rupestres que se estendem de Minas Gerais à Bahia, na Cadeia do Espinhaço. Paepalanthus Mart. é o maior gênero da família e apresenta cerca de 450 espécies, sendo que Paepalanthus sect. Diphyomene Ruhl. possui cerca de 20 espécies que já pertenceram a diversas categorias taxonômicas. Com o objetivo de correlacionar a anatomia e a taxonomia desta seção, além de levantar caracteres diagnósticos para suas espécies, foi estudada a anatomia de folhas, brácteas e escapos. Folhas e brácteas de Paepalanthus sect. Diphyomene apresentam diferenças na forma e no espessamento das células epidérmicas; no espessamento do mesofilo; na disposição dos feixes vasculares; presença ou ausência de hipoderme; diferente forma e composição de parede das células da extensão de bainha do feixe vascular; forma e constituição da margem e presença ou ausência de parênquima aqüífero na face adaxial. No escapo, foram observadas diferenças quanto ao número e contorno de costelas e extensão da medula. Assim, a proposta de divisão de P. sect. Diphyomene em duas categorias é corroborada. São caracteres diagnósticos para as espécies: presença de parênquima aquífero na face adaxial e ausência de extensão de bainha do feixe vascular em folhas de Paepalanthus urbanianus; presença de feixes vasculares distribuídos em ordem decrescente de tamanho em direção à margem em folhas e brácteas e contorno triangular do escapo em P. flaccidus, presença de nove costelas em escapos de P. acanthophyllus e dez em P. macer. Foi elaborada uma chave de identificação das espécies de Paepalanthus sect. Diphyomene com base nas características anatômicas levantadas

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

Gerenciamento dos resíduos de serviços de saúde da Unidade de Terapia Intensiva do Pronto Socorro do Hospital das Clínicas da Faculdade de Medicina de Botucatu – UNESP

Health care waste (HCW) is the type of waste that results from activities performed in health care services during care provision to humans or animals. Presently, according to RDC 306/04, issued in 2004 by Anvisa, and Resolution no. 358/05, by CONAMA, waste groups have the following classification: Group A (biological waste), Group B (chemical waste), Group C (waste containing radionucleotides), Group D (common waste) and Group E (piercing and cutting waste). In Brazil, 149 tons of wastes are collected every day, and HCW corresponds to approximately 1% to 3 % of that total. An efficient way to adequately manage HCW is through the Health Care Waste Management Plan (HCWMP), and it is possible to reduce the risk posed by certain materials in addition to ensuring disposal in an ecologically correct and economical fashion. According to the Pan-American Health Organization (PAHO), the management process enables health care establishments to adequately manage waste. Hence, there is greater control and reduction in the health risks caused by infectious or special waste, in addition to facilitated recycling, treatment, storage, transport and final disposal of solid hospital waste in an environmentally safe fashion. To evaluate the management of HCW of Groups A and D from the Intensive Care Unit of the University Emergency Hospital - FMB - UNESP in the city of Botucatu according to the guidelines presently in force. The waste flow was followed up, and during four random days in the month of September 2011, waste was quantified by estimating daily and monthly values, according to its classification. : In 2011, the University hospital has produced an average of 57,676.8 kg/month of biological and common waste. By adding Groups A and D, during the four days, approximately 209.8 Kg of waste (202.2 Kg of Group A and 7.6 Kg of Group D) were produced in the establishment under study, which...

Potencial de reciclagem dos resíduos sólidos urbanos do Município de Salto-SP

O excessivo consumo de recursos naturais renováveis e não renováveis combinado com a ineficiência e o desperdício de seu uso geram uma problemática muito atual nos centros urbanos: a grande produção de resíduos sólidos urbanos (RSU) e sua destinação inadequada. O presente trabalho caracterizou o RSU da cidade de Salto – SP a fim de quantificar os materiais recicláveis presentes nestes sólidos, bem como mapear sua origem e o perfil social de sua fonte geradora. Foram utilizadas quinze (15) classes de recicláveis, além do lixo orgânico e rejeitos. Dentre as classes estão: latas de aço; sucatas ferrosas; papel misto; papelão ondulado; embalagens longa vida; polietileno de alta densindade – PEAD; polipropileno – PP; poliestireno (PS); PET óleo; PET refrigerante; vidro; outros plásticos – PVC, materiais compostos de mais de um tipo de plástico e PS expandido; aparas plásticas; latinhas de alumínio e outros alumínios,. Os resultados apontam para uma grande geração de materias recicláveis no RSU em bairros de maior poder aquisitivo. O porcentual total de recicláveis na cidade foi de 38,38%

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

Proposta de implementação da ISO 14001 em uma empresa química

Due to environmental concerns and the current legal requirements, companies are looking for ways to reconcile economic growth with environmental preservation. The purpose of this project is to show the stages of implementation of ISO 14001 in a chemical company and propose changes in chemical procedures creating goals to be achieved. In this paper, the study for the implementation of ISO 14001 is in Viapol ltda., where the lack of environmental management can cause enormous impact to the environment and may generate air, soil and water pollution. The project resulted in a mapping of all the processes and a broad survey of waste and emissions, generating proposals to change some of the processes and and creating programs to achieve the goals and objectives proposed in the Environmental Policy. Adopting an environmental management system (EMS), the company will reduce costs by decreasing the amount of raw material used, shooting down on waste disposal and the amount of it, and increasing productivity. By committing to the implementation of the EMS, companies will be demonstrating a proactive approach to environmental issues and enrich its image to consumers’ point of view

Diagnóstico ambiental no período frio e seco do Córrego Bandeirantes, município de Rio Claro, SP: parâmetros físicos, químicos e físico-químicos

The present study was concerned with checking the water quality, the recovery of the riparian vegetation and vegetation around the springhead of stream Bandeirantes, such as the inadequate disposal of waste along this stream, which is located in Rio Claro, SP, in the period from March to July of 2010. Aiming to propose mitigation measures to reverse the degradation processes and develop activities to help a better awareness of the population directly related to this water resource. The water quality was analyzed by performing monthly sampling in three different points along the stream. The first point of sampling is in the spring of the stream, the second at the region called estradão and the third near its mouth, when it flows into the Ribeirão Claro, a tributary of the right bank of the Corumbataí river. It was calculated from the Water Quality Index (WQI) developed by Cetesb. The results were compared with current law. The riparian vegetation, which is responsible for the protection of rivers and streams, was observed and examined during the field work. The results indicated the stream as class 2 and the WQI has been classified, in the most of the analysis, such as a water of good quality. However, some parameters showed a worrying situation and highlighted the current situation, with waste deposits, furniture and animal waste into the pit of the stream studied

Resistividade elétrica em aterro sanitário e relações com a produção de biogás

The landfill biogas can be an alternative energetic resource as a fuel to electrical energy generators, although, there are not too many techniques to prospect the gas. Usually, landfills receive home waste, which in most are constituted by organic matter whose degradation by anaerobic activity produces the biogas. Geophysics is an important tool in environmental studies and the electrorresistivity, an important method employed in contaminated areas by slurry or necroslurry, including a monitoring for each contaminator flow. The electrorresistivity has not too much application in finding biogas. For this work, two biogas drains in Rio Claro-SP landfill were selected: one whose waste disposition correspond to the initial activities in the landfill and another drain whose disposition started more recently. The result consists in a higher biogas production if compared to the biogas from the older drain. The present paper consists in a monitoring along one year, with dates collection in each fifteen days. These dates were tabled in Excel 2010 program and graphics of resistivity x depth were generated. Hereafter, most variable resistivity values depth were chosen, to further graphics pluviosity x resistivity generation in Grapher 8 program and the biogas output (m³/h) in monitoring period. The use of pluviosity parameter can be justified by its influence above resistivity. The results show that there is a horizon with possibly biogas accumulation. Lastly, the method was effective, although, for any application of geophysical methods, the knowledge about its limitations is necessary; in this case the influence of pluviosity and also that the measurements were made in one single point, it will not show any side variation
