Estudo comparativo entre MDF e MDP utilizados na indústria moveleira

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 ...

Avaliação do potencial de sistemas nanoestruturados inovadores para incorporação de cacau orgânico: estudo da estabilidade físico-química e atividade antioxidante

Ultimamente várias áreas da ciência vêm se unindo a fim de compreender, elucidar, retardar e reverter o processo do envelhecimento da pele. Tal processo deve ser estudado, pois as mudanças no aspecto exterior podem revelar disfunções que ocorrem internamente, além de trazer conseqüências psíquicas sobre o comportamento da pessoa, tanto diante de si mesma como diante das outras. A utilização de matérias-primas naturais orgânicas em formulações farmacêuticas e cosméticas segue uma tendência de mercado, haja vista o grande impulso que o mercado orgânico tem ocasionado na economia. Dentre estas matérias-primas, destaca-se a utilização do cacau orgânico que, pelo fato de ser rico em compostos polifenólicos e taninos condensados, acredita-se apresentar potencial ação antioxidante. Associados a sistemas nanoestruturados inovadores, como os sistemas líquido-cristalinos constituídos por silicones formadores de filme, a ação antioxidante do cacau orgânico pode, dessa forma, ser potencializada. Este trabalho tem como objetivos desenvolver e caracterizar sistemas líquido-cristalinos acrescidos de extrato de semente de cacau orgânico, avaliar a estabilidade físico-química e a atividade antioxidante das formulações obtidas. Realizou-se a caracterização do pó de cacau por microscopia óptica. A partir do pó do cacau, obteve-se extratos hidroalcóolicos do pó, a partir do qual foram quantificados compostos fenólicos utilizando o reagente Folin-Ciocalteu e determinada a atividade antioxidante com base na ação seqüestrante do radical 1,1-difenil-2-picrilhidrazila (DPPH). Posteriormente, o extrato foi incorporado em um sistema constituído por acido oléico e polioxietileno 20 cetil éter, o qual foi caracterizado estruturalmente empregando análises de microscopia de luz polarizada, espalhamento de raios-X a baixo ângulo (SAXS) e comportamento reológico...

Ciência da carne: a linguagem gráfica da anatomia humana

This monograph seeks to provide an exposition and theoretical examination of Ciência da Carne (“Science of the Flesh”), a series of artworks in woodcut printing executed after research into the artistic aspects of Human Anatomy, done throughout the Graduate Course in Visual Arts at UNESP’s Art Institute. Traditional procedures of naturalistic representation of the human figure often adopt the scientific basis of Anatomy as a means of interpreting the surface contours of the body from its inside out. The historical connection between Anatomy and Art, however, is not merely accidental, for it is integral to the development of both disciplines, which find themselves deeply related in the human impulse for self-discovery and reinvention of its own likeness. The series of artworks collected in Ciência da Carne explores, through the particular graphical language provided by woodcut printing, abstract arrangements of isolated anatomical elements, at once removed from the context of traditional figurative representation and from the didactic goals of medical illustration.

Uma proposta de intervenção com atividade física individualizada na deficiência intelectual: um estudo de caso

The practice of regular physical activity has been considered a protective factor against the degenerative processes of the body, acting as a promoter of health, especially for risk groups such as obese and resistant groups exercise adherence as among the intellectually disabled (ID) . This study involved the administration of a training protocol and the physical parameters of longitudinal health in a subject about 43 years, intellectually deficient, hypertensive, obese and with a strong predisposition to develop diabetes and heart disease. The main objective of long-term program was to reduce body weight and normalize blood pressure (BP) after the student's physical activity and preferentially interfere with BP values at rest (ie before the daily schedule). The other objective was to improve general physical fitness. The protocol involved four meetings per week lasting one hour, in addition to participation in the program PROEFA (twice a week with sessions of one hour each), totaling 57 sessions spread over five months. The evaluation protocol included in each session the following tests: blood pressure measurements and heart rate, and amount of physical activity recorded via pedometer. Tests applied before and after the training included: anthropometric assessment, agility test, flexibility test, test drive through vertical and horizontal jumps and endurance to the test bench. The mass (kg) and BMI corresponded to the initial values of 127.7 kg and 42.05 kg m-2, and 5 months after 113.2 kg and 37.48 kg m-2, respectively. The waist-hip ratio was close to 1 after the intervention and this value corresponded to 0.98. For the test of agility (shuttle run) was not found improvement in performance. To test the values of the horizontal jump in pre-test were 52 cm and 56 cm post-test, vertical jump has been improved and...(Complete abstract click electronic access below)

Validação dos parâmetros aeróbio e anaeróbio a partir de protocolo não invasivo aplicado ao exercício resistido - supino reto

The purpose of this study was to investigate the validity of critical force test from maximal lactate steady state (MLSS) during resistance test using straight bench press. Five healthy male volunteers aged (22.6 ± 2.88 years), weight (76.3 ± 11.49 kg) e height (182.6 ± 7.54cm), trained in resistance exercise, and performed four diferent test to determine: one maximal effort (1RM), critical force using the critical power model (force vs 1/time limit - 20, 25 and 30% 1RM). The CF was the linear coefficient and the anaerobic impulse capacity (CIA) was the angular. MLSS was determined using loads of 80, 90, 100 and 110% of critical force. Blood lactate samples were abtained at each 300sec between each stage of total 1200sec. Maximal 30s test (M30) was accomplished with load of 25% of body weight in SBP. The results showed that the 1 RM was 79.4 Kgf (± 16.98), CF 10.1N (± 2.25), CIA 1756.82 N.s (± 546.96) and the R² 0.984 (± 0,02). The MLSS occurs at 100% CF load. The lactate concentration at the MLSS was 2.2 mmol/L (± 0.77). Significant correlation was observed between MLSS and CF on SBP (r = 0.88 p = 0.05). In M30 the minimum, mean and peak power were (25.0 ± 4.9, 28.0 ± 4.9, and 30.0 ± 4.6 kgf.rps, respectively). The fatigue index was 18.0% (± 6,8). The M30 was significantly correlated with Ppeak and Pmean (r = 0.98 for both, p = 0.003). The CF means has been validated to predict the resistance training and the CIA show to be a representative anaerobic parameter in straight bench press.

As compras coletivas como estratégia do comércio na atualidade: análise do consumo e das redes geográficas na região metropolitana de Campinas

The collective purchases translate into new business strategies that so far are poorly studied, but they have modifyied considerably the forms of consumption through the consumers individualisation, which causes changes in society's routine. The analysis of the theme was performed by study cases of collective shopping places in the city of Campinas, country of the state of São Paulo, and on its influence in the metropolitan area, which intented to understand, through custumers interviews, the contradictions and peculiarities of this service that has increased each day more . For this purpose, the research methodology is focused on the consumer , that's because the process of productive change tied to forms of trade and distribution of goods have been transforming social values considerably, based increasingly on impulsive consumming . Thus, to understand how the electronic commerce and more specifically the collective shopping websites works, it's necessary to examine the forms of commerce and the consumer's behavior in order to explain the city organization and the contradictions of the geographic space

Uma discussão sobre a base metafórica das figuras de linguagem

The aim of this work is the analysis of some figures of speech, which is based on the existence of a nature of metaphorical process. The research starts from the hypothesis that these figures form themselves by this process. The study is based on the reading of the chapter “Figuras de linguagem”, which is in the work Lições de gramática de usos do português (NEVES, in the press), in which are given lessons about figures of speech, using literary texts and suggesting a metaphorical base for the general sustenance of the analyses. From these lessons, that had already directed groupings and analyses in Seves (2009), a reanalysis was done according to a theoretical orientation which basis is cognitivist, what contribute to this idea about the origin of the figurative processes. The bases of the theoretical orientation, in this sense, are: the conceptual metaphor theory (LAKOFF; JOHNSON, 1980), which considers metaphor as a cognitive (mental) process; and the current of the systematic metaphor (CAMERON, 2005 apud SARDINHA, 2007) that defends the attention to the recurring use of metaphor in real language, before doing assertions about the mind’s functioning. The analyses indicated these conclusions: a) the theory of the conceptual metaphor can be considered efficient for the foundation of the analyses, what implies a minimization of the metonymic component in the exam of these figures; b) and in the basis of the majority of the founded figures it is evident the nature of a metaphorical process

Técnicas de análise multivariada com aplicações a dados de natureza biológica

A análise estatística multivariada, extensão da análise univariada, consiste num conjunto de técnicas estatísticas, aplicadas quando há diversas variáveis relacionadas simultaneamente, sendo todas elas, em princípio, consideradas importantes no fenômeno em estudo. É de grande aplicação a conjuntos de dados das mais diversas áreas do conhecimento, principalmente da área biológica. Seu desenvolvimento teve um grande impulso na primeira metade do século passado. Entretanto, devido a complexidade dos cálculos matemáticos, principalmente envolvendo operações com matrizes de altas ordens, as aplicações somente se popularizaram nos dias atuais, com o desenvolvimento dos computadores e aplicativos computacionais. Técnicas estudadas: distâncias multivariadas, componentes principais, análise fatorial, correlações canônicas, análise de correspondência, teste t² de Hotelling, análise de variância multivariada (Manova), teste de normalidade multivariada, igualdade de matrizes de variâncias e covariâncias para populações multinormais

A luta pela terra: repressão política aos movimentos socioterritoriais no Pontal do Paranapanema de 1990 a 2009

A questão agrária do ponto de vista estrutural se insere nas formas combinadas, desiguais e contraditórias do capitalismo. A repressão política manifestada contra os movimentos socioterritoriais será o fundamento de elaboração de nossa argumentação e a preocupação central desta monografia. O ponto de partida de nossa proposição foi caracterizar e dimensionar espacialmente os casos de processos judiciais criminais impostos às pessoas envolvidas no processo de luta pela terra, que integram majoritariamente os movimentos socioterritoriais no Pontal do Paranapanema, dentro do período de 1990 a 2009. Outra análise foi verificar os componentes dos processos judiciais criminais, pesquisando as sentenças finais disponíveis na página digital do Tribunal de Justiça do Estado de São Paulo, bem como as matérias publicadas sobre os casos e elaborar reflexões sobre esses componentes a partir das leituras geográficas por meio dos conceitos de espaço e território. Desta forma houve o impulso de incorporar a dimensão espacial da repressão política. Consequentemente aprofundamos a análise sobre as sentenças judiciais criminais e procuramos entender a politização do judiciário e sua espacialidade. A compreensão da espacialidade da repressão política na 1ª e 2ª instância dos processos judiciais criminais movidos aos movimentos socioterritoriais constituiu outra passagem importante do trabalho. Conseguimos também ampliar nosso estudo pela comparação da repressão política a partir do estudo dos casos do Pontal do Paranapanema no Brasil e Córdoba na Argentina. Manifestamos também a necessidade de estabelecer diálogo com alguns marcos teórico-metodológico sobre a categoria geográfica território com o intuito de colaborar com o nosso esforço de explicar a repressão política aos movimentos socioterritoriais no Pontal do Paranapanema entre os anos de 1990 e 2009

Campesinato e agrohidronegócio canavieiro no Pontal do Paranapanema: os desafios para a transição agroecológica

This paper appears in order to promote a discussion on the use and ways of working with the land. For this, we present a scenario of conflict initiated in Pontal do Parananema, São Paulo, Brazil, between the peasantry and the agrohidronegócio. The Pontal is a territory marked by agrarian and land conflicts, originated by the illegal occupation of land by the squatters, the decimation / expropriation of indigenous, and deforestation and environmental devastation. This conflict is represented today by the sugarcane agro-industrial capital companies on one side, and the other peasants. The expansion occurs agrohidronegócio strongly from 2005, due mainly to the change in the energy matrix of the country and state incentives with strong momentum in the production of flex-fuel vehicles. Rural agrarian reform settlements, made possible by the state under pressure from social movements, are spatialized in 16 municipalities with a total of 112 settlements, occupying an area of 139. 682 hectares, seating 5. 892 families. These families have seen their possibilities of social reproduction increasingly suppressed by the advance of sugarcane agrohidronegócio in the region, which suffocates the living spaces and work of these peasants. Front of it, agroecology is an alternative for these workers to ensure their reproductive possibilities. Agroecology also arises as a means of confronting agribusiness model, adding elements to the environment, such as the eradication of the use of pesticides and considering the dynamics of nature to promote agriculture, and social order, contributing food sovereignty and the production of healthy food and diversity to the population...

Os jogos frutais e o poema: natureza viva; natureza-morta

The (usually rotten) fruit theme or motif is recurring in Ferreira Gullar‟s poetic work (from A luta corporal, 1954, to Em alguma parte alguma, 2010). It can be said that the semantic-metaphoric field comprises metapoetic to political and social issues –expressive aspects in the author‟s trajectory. Thus, starting from the fruit topic which is characteristic of the bucolic-pastoral poetic tradition and tracing its presence in Brazil, this paper aims, by analysing some of Gullar‟s poems, to reflect on the peculiar way the problem is subverted in his lyric.

Educação pública nas metrópoles brasileiras: impasses e novos desenlaces

O livro Educação Pública nas Metrópoles Brasileiras: impasses e novos desenlaces apresenta um conjunto de artigos sobre preconceitos que persistem nas práticas educacionais contemporâneas, sobretudo nas grandes cidades como São Paulo e Rio de Janeiro. De outra parte enfatiza como a teoria psicanalítica combinada com o método etnográfico, praticada em instituições educacionais, pode ser útil para a reconstrução de padrões de autoridade imprescindíveis ao ato educativo.

Considerações sobre a atualidade da formação cultural/educacional: novos desafios para a pesquisa

This paper aims to draw some outlines of what I understand to be background for possible investigations that examine the cultural / educational problems in Brazil from the perspective of Critical Theory. Under the light of these outlines I intend to present two directions of research which are the main objectives of the research project I develop within the Department of Educational Psychology of College of Sciences and Letters of Unesp in Araraquara. In particular, it is necessary to understand the internal deformation that education suffers as a concrete substance of the teaching process in schools, which makes an empirical investigation how the cultural industry’s schemes become present in the “didactic pedagogical scene” necessary. On the other hand, the elucidation of this problem requires a theoretical investigation about the broader process of constitution of today’s subjectivity under the impact of that industry. Both goals set forth herein are intended to provide subsidies to make readings about new educational demands possible in Brazil.
