Introduction: In the Web environment, there is a need for greater care with regard to the processing of descriptive and thematic information. The concern with the recovery of information in computer systems precedes the development of the first personal computers. Models of information retrieval have been and are today widely used in databases specific to a field whose scope is known. Objectives: Verify how the issue of relevance is treated in the main computer models of information retrieval and, especially, as the issue is addressed in the future of the Web, the called Semantic Web. Methodology: Bibliographical research. Results: In the classical models studied here, it was realized that the main concern is retrieving documents whose description is closest to the search expression used by the user, which does not necessarily imply that this really needs. In semantic retrieval is the use of ontologies, feature that extends the user's search for a wider range of possible relevant options. Conclusions: The relevance is a subjective judgment and inherent to the user, it will depend on the interaction with the system and especially the fact that he expects to recover in your search. Systems that are based on a model of relevance are not popular, because it requires greater interaction and depend on the user's disposal. The Semantic Web is so far the initiative more efficient in the case of information retrieval in the digital environment.

The Assistive Technology makes the lives of people without disabilities more practical, but for people with disabilities it can make things possible. For these individuals can provide the conditions, making their limitations are not obstacles to their social and personal empowerment, and may contribute to their effective participation in tasks that were previously impossible, such as remaining seated correctly. A segment on which the necessary assistive technology works, is the adaptation of furniture such as chairs, tables, chairs-to-wheels for individuals with disabilities, as well as cerebral palsy. The study aimed to conduct a survey and brief description of theses and dissertations produced in Brazil on furniture adapted for students with cerebral palsy. We made searching in databases of libraries of major universities and federal state national banks, theses and dissertations. Nine studies were selected for description. It was concluded that there is a considerable array of professionals, both in engineering as the field of rehabilitation, to contribute in the adaptation, creation and even the manufacture of furniture for children with cerebral palsy and that the securities most studied are the chairs and their components.

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)

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

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

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...

Increasingly, the furniture market is competitive. The construction industry presents itself in growth, mainly due to the lines of existing incentives and tax credits established by the government, assisting the impulse to purchase real estate, building materials and furniture. Factors that promote and strengthen the sector's growth. With high demand from the furniture market, demand for higher quality and increasing technological advances, research is often undertaken in search of solutions for process improvement and product features, focusing on the production of materials less harmful to the environment, provision of raw press to lower cost, improve the production process and product development of cost-effective. This research focuses on the comparative study between two materials widely used in furniture manufacturing. MDF (Medium Density Fiberboard) and MDP (Medium Density Particleboard). The subject provides the focus in furniture production, presenting and comparing data collected from three companies producing panels between physical and mechanical characteristics of the materials, also presenting some of the main factors of influence on the quality of the panels, their features and applications on mobile. The study shows the high potential of using the MDP (Medium Density Particleboard) in furniture designs, as well as MDF (Medium Density Particleboard), favoring the final terms of the project , resulting in better utilization of each material , avoiding waste and increase unnecessary cost . Currently, several projects are developed in MDP and MDF furniture, where there is no relevance to their characteristics regarding their limitations. Many of these furnishings are designed without a specific study of the best use and positioning of each material, with better utilization , favoring collateral design , especially furniture designed exclusively for each environment . The lack of technical ...
