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

Aproveitamento de resíduos de laminação da madeira para a produção de painel estrutural

Products derived from wood or engineered products are becoming interesting alternatives to the replacement of solid wood in various applications, from structural components to the furniture industry and packaging. Among these products, there are panels built by strands, particles and fibers, each one having their particular characteristics and potential of use. Since the different types of panels are produced, waste generation is part of the process, and that more technological it is, it still generates losses of raw materials. Based on the need for rational use of raw materials and using almost full of industrially processed wood, It arises the proposal of this work, which seeks to use waste from the lamination, like pieces of strands, broken strands, strands rough, cracked strands to produce panels with structural characteristics of the OSL panel (Oriented Strand Lumber), LSL (Laminated Strand Lumber) and OSB (Oriented Strand Lumber). Besides the use of waste, this paper seeks an alternative to the use of the adhesive, because the industry uses formaldehyde-based adhesives, which over the press, they emit large amounts of formaldehyde, which is very aggressive to humans and environment. The panels made with polyurethane resin based on castor oil and hot-pressed were characterized by physical and mechanical tests according to specifications of European Standard (EN). High values of tensile strength, elastic modulus and density were found in the results of tests. Adding to stable values of swelling and moisture content, the panel studied adds attractive features to the panel market, especially in the civil construction

Desenvolvimento de metodologia para a obtenção da cubicagem de madeira em toras empilhadas através de imagens digitais

Obtaining accurate estimates of the volume of stacked wood is important in view of the increasing value of wood as raw material. Therefore, the forest companies have become increasingly concerned about the methods currently used to convert cubic meters for stereo. In this context, emerged the need of optimizing the measurement process and accuracy of the volume of stacked wood. For this, companies have been testing methods with greater efficiency, speed and low operating cost. Existing methods made through approximate equations, and also by determining the conversion factor, called the stacking factor (Fe), are questioned, due to errors and inaccuracies. The use of digital photographs is an alternative method that would minimize operator intervention, allowing greater control and speed the process, thus eliminating part of the imprecision of the traditional method. The use of the method is viable, due to present an error of about 10% while traditional methods showed an error of 17%

Caracterização físico-mecânica de painel de MDP produzido com madeira de Eucalipto e Bracatinga

This work is the production of particleboard of particles reconstituted from MDP (Medium Density Particleboard) adding particles in the inner layer of Mimosa Scarelli, popularly known as bracatinga, the ratios of 0%, 25%, 50%, 75% and 100%. The panel produced is composed of three layers, two external particles with smaller particle size and an inner layer composed of particles of larger particle sizes. Assays were performed based on physical and mechanical NBR 14.810/2006 for the determination of the board density, thickness swelling, water absorption, moisture content, bending strength, shear strength and residual moisture, and testing of particle size not existing in the standard cited. The results were analyzed and compared the results of the commercial boards made from 100% eucalyptus, based on the limits specified by the ABNT NBR 14.810/2006. The values of the tests were close to the normative specifications indicating positively the production of MDP with wood decay.

The present study begins with the cultural, economic and social changes that were triggered by the new communicational reality e how these changes affected the ways of acting and thinking of society. In this context, we look at how modern organizations are adapting to this new demand and how the public relations may participate in the development and management of communications strategies to relate to the new publics arising through the consolidation of digital media

Proposição de um checklist de acompanhamento de processos construtivos habitacionais em wood-frame

The need for housing in Brazil is very large, and despite government efforts to address this issue, the housing deficit is too large. When analyzing markets without this problem, it is concluded that one of the factors that influence this model is the construction adopted by Brazilian society that is in masonry. Alternatively, the system can be used in constructive Wood-frame. To apply this system in Brazil, one can say that the workmanship and the materials available to meet the demand would be created in a short period of adjustments and capabilities, but identifies himself as one of the biggest problems the planning and management of works. And one of the tools for solving this problem is to use a checklist of the activities of constructive process, avoiding forgetting or not aware of the activities necessary to complete the project

Conflitos e conciliações: a relação da personagem Blanche DuBois, de Streetcar Named Desire, com a sociedade americana moderna

This paper presents a reflection on the relationship of the character Blanche DuBois, the protagonist of Tennessee Williams’s play A Streetcar Named Desire, with the society in which she is inserted. There is also a brief analysis of the construction of this character. To do this, the historical context of both the play and the author were studied, as well as his biography, which has great relevance in his work, and also a concise analysis of the elements presented in the literary work itself. In order to have an overview of Blanche, a few lines of this character were collected, as well as the lines of other characters that refer to her and some opposing viewpoints. The aim of this paper is to confront the character’s psychological and social conflicts, setting them in the context of modern American society

Análise granulométrica do compósito cimentício produzido com adição de resíduos de madeira e escória

Since the early twenty-first century, the construction sector has been the second largest on the rise in the Brazilian industrial sector, with a growth of 1.4% in 2012, and is likely to remain at this level for a long time. However, unlike decades ago, the industry has been seeking in its manufacturing process, sustainable materials, encompassing in their works the concept of sustainability. Thus, the timber sector seeks to satisfy a market increasingly demanding, innovating techniques and utilization being less aggressive to the environment. The purpose of this study was to produce and evaluate the mechanical strength of the composite cement with the addition of wood residues and slag low oven. Therefore, it was made 42 specimen cement-slag-wood, carried out in two steps. Since at the first, it was varied only the slag particle size, and at the second, through the best result of the previous step, it was varied the wood particles granulometry. The mechanical performance of the composite was evaluated by the results obtained in the compression test and the physical test for determining the density of the material. In the first step of the process can be concluded that the best result was achieved with the use of slag particles retained on the 60 mesh sieve. In the second phase of the study concluded that the best results were achieved with wood particles with the large particles, i.e. particles retained on the 10 mesh sieve. Both in the first and in the second step it can be seen that there has been the influence of the particle size of the waste materials. With the obtained results, could be evaluated that the use of waste for the production of cement-slag-wood composite showed lower performance when compared to the results obtained in studies without the use of waste. However, some applications are feasible to be performed with the use of composite wood-cement-slag

Diagnóstico socioambiental de um alojamento estudantil público e da comunidade do entorno: um estudo da relação entre a universidade e a sociedade

Dormitories are places offered by Brazilian public Universities to undergraduate students evaluated as socio-economically less favored aiming to guarantee the housing of the student in the locality they take a given undergraduate course, once housing is one the points which compose the tripod that supports the concept of student permanence, along with conditions of transportations and food. These places, however, present problems in their management, specially the ones related to social and environmental questions, caused by wrong attitudes and pre-concepts of their own residents, other students and the communities who live around them. So, this project aims to identify and analyze the socio-environmental conditions of a students’ dormitory located in Botucatu/SP which is supported by the Universidade Estadual Paulista “Júlio de Mesquita Filho” (Unesp) as well as the community that surrounds it. The data collecting is based on an exploratory research characterized for interviews that used semi-structured questionnaires and for the creation of a photography record of the region. The obtained data corroborated the tendency of an increasing gap between the Brazilian public universities and the society as well as to the disengagement of them and their students. This diagnosis has permitted to build proposals of educational interventions based on Permaculture, Agroecology and Critical Environmental Education to the improvement of the existing relationships among the students who live at the dormitory and among them and the local community. These interventions may be used as subsidies to the development of future research and extension projects to the local community

Tradução e análise dos artigos de Karl Kautsky acerca do imperialismo e seus desdobramentos em relação à economia e sociedade contemporânea e o Brasil

A eminência da Primeira Guerra Mundial efervesceu o debate entre teorias que buscavam explicar as causas e as conseqüências daqueles conflitos. Dentre os principais pensadores da época, Karl Kautsky, editor da revista Die Neue Zeit, era considerado o primeiro discípulo de Marx e Engels, exercendo, através de seus artigos, grande influência social. E foi no ano de 1914 que, através dos artigos O imperialismo e a Guerra, O ultraimperialismo e a Preparação para Paz, Kautsky definiu sua interpretação e expectativas em relação a aquele momento. O conteúdo desses artigos é de primordial relevância para estimar, observando o desenrolar do século XX, o quanto fez sentido suas interpretações. Assim, o objetivo é contribuir ao esclarecimento dos pensamentos deste autor, a fim de ajudar a entender a sociedade mundial contemporânea e o Brasil, quase um século depois de ter feito as publicações mencionadas

Análise das propriedades da madeira de estrutura de telhado após a ocorrência de um incêndio

The present study evaluated the mechanical properties of pieces of wood coming from the roof structure of a residence subject fire in the rural area of Itapeva/SP. The structure was built 25 years ago using wooden beams of the species Guarucaia (Peltophorum vogelianum), where the specimens were removed. The research methodology included qualitative evaluation of the samples, estimating the layer pyrolysis and carbonization of the wood, measuring of density and mechanical tests of compression parallel to grain, tension parallel to grain and shear. The mechanical properties of wood were analytically correlated with the layers carbonization and pyrolysis that are influenced by the temperature and time of fire; these values were estimated at 1000 °C and two hours for the case in question. The results indicate that the strength properties of degraded wood are different from a healthy wood. The level of thermodegradation, in general, can be measured by density, result in weight loss due to decomposition of the wooden components.
