Dentina humana e bovina: estudo comparativo das propriedades físicas e características da hibridização de sistemas adesivos convencionais ou grander modificados: análise em mev

A adesão longitudinal continua a representar um dos maiores desafios da Odontologia moderna. Uma nova proposta para o estabelecimento do equilíbrio da adesão aos tecidos dentários surge, baseada na observação dos resultados obtidos com a tecnologia Grander para revitalização da água. Objetiva-se com o estudo verificar a influência dessa tecnologia nas propriedades físicas de dois sistemas adesivos (convencional e autocondicionante) à partir da medição da tensão superficial e do ângulo de contato; e avaliar a formação e a qualidade da camada híbrida em dentina humana e bovina. A tensão superficial de quatro diferentes líquidos (água, Single Bond- 3M, Primer do Clearfil SE Bond -Kuraray, e Bond do Clearfil SE-Kuraray), foi medida antes e após a modificação pelo procedimento Grander em aparelho goniômetro (Ramé-hart). O ângulo de contato com três substratos distintos (placa de titânio, dentina humana e dentina bovina), foi medido para os quatro líquidos também antes e após a modificação pelo procedimento Grander, também em goniômetro. A formação e qualidade da camada híbrida, foi avaliada em MEV, a partir da confecção de corpos de prova dos substratos humano e bovino, devidamente embutidos, preparados em lixas de variada granulação até a exposição de dentina, submetidos ao procedimento adesivo (SB ou CSEB) normal ou grander modificado, recebendo ao final dupla camada de resina composta Z250-3M, fotopolimerizada por 40s. Após armazenamento em estufa bacteriológica por 24h, os procedimentos para análise ao MEV foram realizados (fixação, desidratação, secagem e metalização). A estatística de Análise de Variância ANOVA e Teste de Tukey 5% revelou que: houve redução estatisticamente significante da tensão superficial para todos os líquidos Grander modificados; houve redução estatisticamente...

Análise do comportamento térmico de paredes de madeira

This study consists in the observation and evaluation of the thermal behavior and distribution of wood composite walls, MDF – Medium Density Fiberboard, HDF – High Density Fiberboard, OSB – Oriented Strand Board and EGP – Edge Glued Panel. This study had the objective to present the experimental thermal behavior and to verify which one fit the thermal comfort standards for human labor For this work, was developed a thermal chamber, with one interchangeable side, so the wall prototypes would fit for each experiment. We studied walls made of MDF, HDF, OSB and EGP, which one had its own distinct behavior due to the panel construction. The EGP wall had shown the most reliable material for this usage at high temperatures. With this work, it was demonstrated the importance of choice for the right material and construction method for wooden composite walls, because if they were scaled poorly, the people exposed to them would be uncomfortable by the proportionate environment, and the costs for a resizing would be too high

Análise ambiental simplificada no entorno de águas superficiais na bacia do rio Corumbataí (SP)

The basin of the Corumbataí river is of vital importance to over 600 thousand people, who depend on its waters for consumption. The Simplified Analisys of Environmental Impacts in the Areas Surrounding the Surface Waters of the Drainage Basin of the Corumbataí River (SP) is aimed at defining the areas which are most susceptible to degradation or already damaged and propose engineering solutions according to the environmental problems identified. Using a questionnaire to indicate possible impacts in the surroundings, I related human actions to these damage and quantified them. Having studied the basin extensively and selected 42 areas - generically identified as points and grouped as sub-basins and according to the soil usage -, I was able to identify the main environmental impacts in the basin as: sugar cane monoculture, lack of riparian forest, damaged areas due to mining, the bad state of rural roads and bridges, rubbish disposal alongside roads or directly into the river, accelerated and unplanned expansion of residential and industrial areas into the rural areas and river sources, and Rio Claro's untreated city wastewater

Infância, família e escola: análise dos significados da Infância e dos Direitos da Criança

This study aimed at analyzing the meanings of Children and Child Rights awarded by the kindergarten children and their educators, parents and teacher. Interest in the subject arose from the participation of the University Extension Project, conducted at the Department of Education, UNESP, Bauru, called The Rights of the Child: ECA in school. Since then, the question arose: to what extent we have visibility of meanings that educators and the child has on the Rights of the Child relating to the specifics of childhood? The research followed the tenets of qualitative research, methodological procedures and adopting the observation in a classroom from kindergarten (K II), semi-structured interview through leisure moments, with the class of aged five years and a questionnaire for family and teacher. The research adopted as reference material, studies of the area of Sociology of Childhood, History of Childhood, Public Policy, Legislation Related to the theme, and an overview of psychogenic to talk about the morality of children. The results showed that parents and caregivers understand childhood as a stage of child development, marked by jokes and fancies, in which the family and the school has an important role in this process. In what concerns the children's rights, there are contradictions in the legal aspects and the situation of children today. The results showed that children's childhood is characterized by recreational activities, and adults are responsible for caring for them. And it comes on the Rights of the Child noted that there is a confusion between rights and duties because they are in a phase of moral heteronomy. The findings indicate the need for wide dissemination on the Statute of Children and Adolescents, especially in preschools in line with families to practice it a new look at childhood, conceiving children as subjects...

Imagem e comportamento do vampiro contemporâneo: uma análise semiótica

O presente trabalho propõe discutir as produções literárias contemporâneas sobre a temática do vampirismo. Este estudo se fundamenta em análises de textos por meio da observação das práticas discursivas que os constituem. Tomando como corpus os romances Crepúsculo e Lua Nova de Stephenie Meyer, as observações partem dos pressupostos teóricos da Semiótica Discursiva e da Análise do Discurso, aos quais são incorporados estudos sobre cultura, sociologia e identidade. Parte-se do princípio de que o discurso é produto da cultura e, desse modo, incorporam-se a ele fatores históricos e sociais. Por essa razão, torna-se importante examinar os elementos dialógicos e intertextuais dos textos anteriormente apontados em relação às outras produções que tratam do mesmo tema e de outros possíveis, encontrados no corpus. Assim, busca-se compreender primordialmente os mecanismos fundamentais que tornam o texto um objeto de comunicação e de significação

Análise da dinâmica do uso da terra e sua interferência em enchentes na área urbana do município de Americana (SP)

Due to an intense process of population growth and urban density in Americana (SP), mainly due to the development of the local textile industry after 1970, there was, concomitant to the occupation of the margin of rivers and streams, soil sealing that increased the level of superficial runoff, triggering frequent floods. Based on the analysis of these processes we investigate the conditions of one densely urbanized area of the county, the Córrego do Parque, in three time series, 1977, 1996 and 2008. Taking as the starting the characterization and spatial distribution of landscape physiography, we prepared thematic letters and synthetic maps digital scale 1:10,000 from photointerpretation of aeroframes. The thematic maps were produced by scanning with subsequent edition using the software Auto-Cad Map. Checking the data and of geographic coordinates with GPS (Global Positioning System). Regarding land use classes, we used the description of the Soil Conservation Service (1975) which allowed us to get the Curve Number parameter, which will be used in hydrologic modeling for verification of flooding (Tucci, 1989). For the process of hydrologic modeling, we used models based on Methodology Object Oriented Modeling Applied to Water Resource Systems, Viegas Filho (1999), using the computer program called IPHS1, which uses models of the Soil Conservation Service (SCS , 2004), for conversion of rainfall-runoff and the spread of excessive rain. The results indicate that increased waterproofing generated by the change in use and occupation over the past decades promoted the increased surface runoff and drainage system overload, increasing the intensity of floods

Suitable computacional tools allow to build applications that can link information to its physical location, and represent them into visual and interactive schemes, e ectively reaching the power of visual comunication. This leads the user to synthesize information in a simple and e cient way. These applications are linked to the de nition of Geographic Information System (GIS). GIS are comprised by many concepts and tools, which have the main purpose of collecting, storing, viewing and processing spatial data, obtaining the information needed for decision making. Within this context, this paper presents the Conception and Implementation of a Control System for Urban Forestry through Integration of Free and Open Source Software. This conception arose from the need of an Environmental Project developed by the Agriculture's House of the city of Regente Feij o, which has as main objectives cataloging and management of urban a orestation of the municipality. Due to this diversity of concepts, the challenge in building this system is the integration of platforms that are involved in all stages: collecting and storage of data, including maps and other spatial information, operations on the stored information, obtaining results and graphical visualization of the same. After implementation, it was possible to provide for the system users an improvement in the capacity of perception in the information analysis and facilitate the process of decision making

Análise de condicionantes geológico-geotécnicos para o rompimento de pequenas e médias barragens de terra: estudo de caso na bacia do rio Jaguari Mirim no município de São João da Boa Vista, SP

The act of containing water is one of the most practiced by the civilizations along history, in the will to increase the offer of water to many uses. The raise of environmental worries surround many human activities has given a big attention to dams. Indeed, the environmental consequences about dams are proporcional to their size, what gives to the big dams a more detailed Project and a bigger political concerning that increases the built, estability and maintenance of them. Then, the projects of medium and small dams are weak, limitaded to handbooks, textbooks and empirical recommendations, while the constructions of small dams are growing everytime more. With that being said, the present work intends to analise the geological and geotechnical conditionants that can cause break of small earth dams by making a case study in the Jaguari Mirim Watershed, located in the city of São João da Boa Vista (SP), and can be used to encourage the concern with small dams. In the area of study were identificaded, from satellite images, 248 dams. The map of physiographical compartmentalization defined by Pilachevsky (2013) was used to define the locations in the study área that would have bigger risk to the break of dams. Then, 9 of this dams were analised in field research, using references made by Cerri, Reis e Giordano (2011) and the risk of the analised dams were defined. A study about this type of structure is highly necessary to avoid big damages. An analysis of the geological and geotechnical conditionants that can cause break of dams guides the project in a way to avoid adverse consequences, especially when integrated with locacional conditions observed in the place of the dam’s building
