O Corpo do grupo corpo: os movimentos das obras Benguelê, Lecuona e Onqotô

In this research, we invite to reflection by a phenomenological gaze on the body, through the description of some works of contemporary Brazilian dance company Grupo Corpo. This Company was chosen intentionally to give us elements in their creations to interrogate the understanding of the body and sensitive. Thus, as we launch issues in this dissertation: that body dance in Grupo Corpo? And as we can see, a phenomenological approach, an understanding of the body and sensitive works in that company? Building on this, the works are to be questioned Benguelê (1998/2003), Lecuona (2004) and Onqotô (2005). It is intended, through these works, coreological approaching the discourse of philosophical discourse and give movement to phenomenological thought of Maurice Merleau-Ponty, in special the sensitive, flesh of the body, the investment in the sensory world as a merger, calling the know body and its power to take chances, to incorporate the world, language, culture, create and choose. Thus, these openings is where thought enters this research. This consistency, we used the phenomenological attitude of Maurice Merleau-Ponty as a methodological approach, since in their study the philosopher takes a look expressive on the body, forming a sensitive language that is expressed in the movements, which deepens the arguments of the Phenomenology a new arrangement for knowledge as a result of our experience in the lived world. The reflections presented here aim to take us to the amazement, the unthinking, whom many still impose epistemological challenges, including understanding the body of knowledge and sensitive

Acúmulo de metais pesados em cana-de-açúcar mediante a aplicação de lodo de esgoto e vinhaça

O uso de resíduos agroindustriais pode acumular metais pesados no solo e na planta. O objetivo deste trabalho foi avaliar os efeitos do lodo de esgoto e/ou vinhaça, aplicados no solo, disponibilizando Cd, Cr, Ni e Pb ao solo e quantificar as respectivas concentrações em plantas de cana-de-açúcar, após três aplicações anuais sucessivas. O experimento foi conduzido em condições de campo, com parcelas experimentais de cinco linhas espaçadas de 1,5 m e 10 m de comprimento. O delineamento experimental adotado foi o de blocos casualizados, com três repetições. Os tratamentos avaliados foram: 1. Lodo de esgoto com 100% de N; 2. Lodo de esgoto com 200% de N; 3. Vinhaça com 100% de K; 4. Vinhaça com 200% de K; 5. Lodo de esgoto+vinhaça com 100% de N e K; 6. Lodo de esgoto+vinhaça com 200% de N e K; 7. Testemunha (fertilização mineral). Os baixos teores de metais pesados (Cd, Cr, Ni e Pb) disponíveis no solo e nas partes das plantas de cana-de-açúcar indicam que o lodo de esgoto e a vinhaça, empregados nas doses mencionadas, não apresentaram, após três aplicações anuais sucessivas, potencial de contaminação do sistema solo-planta.

Razão e Fé: estudo do grupo de oração como prática complementar na promoção à saúde

The World Health Organization (WHO) has given special attention to therapeutic procedures other than those practiced in conventional therapy, including homeopathy, phytotherapy, spiritual therapies and prayers, making possible the transition from a mere medicalizating model to a holistic view of the human being. This trend, earmarked in 1978 at the Alma-Ata Conference, questions the ability of technological and specialized medicine to solve the health problems of humankind. In Brazil, the onset of the Brazilian unified health system in 1988, introduced changes in the population s health care model where, within the scope of basic care, emphasis has been given to the Family Health Program since 1994. In this scenery, there is a broad area of complementary practices used in promoting health and preventing and treating diseases to support an understanding of the habits and beliefs underpinning popular practices. The purpose of this study was to analyze the perception users participating in the Peace and Balance group of the Family Health Unit of Nova Cidade, in Natal, Rio Grande do Norte, started in 1999, have of the relationship between the experience of prayer and the changes that may have taken place in their lives after joining the group. It is a case study of descriptive nature and qualitative approach. The data were collected during focus group interviews between January and February 2007, using as tools a questionnaire to describe the research participants and a discussion outline. The theoretical support approached the following: religion and the evolution of thought; complementary health practices; and religion as a complementary health practice. Those interviewed reported, as results of such experience, a reduction in stress and depression, an increase in socialization and self-esteem, improved family interaction, comfort, safety, assurance, improved blood pressure levels and a decrease in the use of antihypertension medication and psychopharmacs. Although most professionals do not consider attention to the religious and spiritual aspects an effective therapeutical complement in health care, its understanding and practice may democratize knowledge and relationships, out of which they can learn how to make health production more effective, strengthening assurance and confidence, and developing and expanding soft technologies aimed at health care promotion and wholeness

Argamassas do grupo escolar Augusto Severo/RN: caracterização e incidência de manifestações patológicas

The search for cultural heritage preservation should be a constant, in order to minimize the lost of historical and cultural identity of a country. As part of this cultural heritage, highlights the importance of historical buildings. For the principles of restoration are met its important to know the state of conservation and the existing materials. Given the above, this work aims to study the pathological manifestations of the mortar coating from the Grupo Escolar Augusto Severo. For this, was conducted historical survey of the building, on-site visits with visual observation, collecting samples of mortar coating and characterization through visual and laboratory analysis, XRF, XRD, TG/DTG, OM and SEM-EDS. From the observations, pathological manifestations were found as: cracks, detachment of the coating, dirt, use of inappropriate material basis of cement, efflorescence, mold and mildew and also incompatible material base of cement. It was found that the pathological manifestations were intensified due to lack of coverage in some spots and especially the abandonment of the building, that many years does not have restoration or any other type of preventive and corrective maintenance. The results of laboratory tests indicated that the mortars studied are based on lime, with calcitic nature, and siliceous aggregate, with the presence of clay in two samples. From the samples collected, two are composed of lime, sand and clay and two by lime and sand. In this regard, it is important to conduct periodic inspections and maintenance, as well as carrying out restoration with use of material compatible with the original

Desenvolvimento de nanocompósito (hidroxiapatita/ poliuretano) pela gelação (gelling) de poli ( álcool vinílico) (PVA) para remoção de metais pesados

Removing microcontaminants from effluents is a challenge today, because of its high cost and low efficiency, especially in the treatment of effluents containing heavy metals. An alternative that has emerged is the use of biodegradable nanocomposites, which exhibit good removal and recovery performances, in addition to its low cost. With this in mind, the present study aimed to develop and characterize a nanocomposite based on hydroxyapatite (HAP), polyurethane (PU) and polyvinyl alcohol (PVA) for removing heavy metals. Thus, the research was conducted in several steps: i)- Physico-chemical and microbiological hospital effluent characterization; ii)- Production of hydroxyapatite by aqueous precipitation technique, and their characterization; iii)- Production of the nanocomposite in which the hydroxyapatite was added to the polyurethane prepolymers and then the polyvinyl alcohol/hydroxyapatite film was produced; iv)- Polyvinyl composite without film PU/HAp was also produced in the proportions of 20 and 40% HAp; v)- The composites was characterized by the techniques of XRD, FTIR, SEM / EDS, BET, Zeta Potential and TGA; vi)- The sisal and coconut fibres were washed and dried for comparative tests of adsorption; vii)- Adsorption tests for evaluating the removal of heavy metals (nickel and cadmium). Initial screening adsorption capacity (HAp; PU/HAp - 20 and 40%; PU / HAp / PVA), kinetic studies of adsorption of Cd (II) by HAp; multifactorial design analysis (factorial design) for identifying the most important variables in the adsorption of Cd (II) by composite PU/HAp. Also comparative analysis of adsorption of Cd and Ni by composite PU/HAp were conducted, as well as comparative tests of adsorption of Cd (coconut fibre) and Ni (sisal fibre). It was possible to verify that the composite PU/HAp 40% showed better effectiveness for the removal of Cd (II) and Ni (II), above 80%, equivalent to the lignocellulosic fibre used and HAp produced. As main conclusion, it can be referred that the composite PU/HAp 40% is an effective adsorvent to wastewater treatment for heavy metal removal, with low cost and high efficiency

Remoção conjugada de metais e óleo de água produzida

Petroleum can be associated or not with natural gas, but in both cases water is always present in its formation. The presence of water causes several problems, such as the difficulty of removing the petroleum from the reservoir rock and the formation of waterin-oil and oil-in-water emulsions. The produced water causes environmental problems, which should be solved to reduce the effect of petroleum industry in the environment. The main objective of this work is to remove simultaneously from the produced water the dispersed petroleum and dissolved metals. The process is made possible through the use of anionic surfactants that with its hydrophilic heads interacts with ionized metals and with its lipophilic tails interacts with the oil. The studied metals were: calcium, magnesium, barium, and cadmium. The surfactants used in this research were derived from: soy oil, sunflower oil, coconut oil, and a soap obtained from a mixture of 5wt.% coconut oil and 95wt.% animal fat. It was used a sample of produced water from Terminal de São Sebastião, São Paulo. As the concentration of the studied metals in produced water presented values close to 300 mg/L, it was decided to use this concentration as reference for the development of this research. Molecular absorption and atomic absorption spectroscopy were used to determine petroleum and metals concentrations in the water sample, respectively. A constant pressure filtration system was used to promote the separation of solid and liquid phases. To represent the behavior of the studied systems it was developed an equilibrium model and a mathematical one. The obtained results showed that all used surfactants presented similar behavior with relation to metals extraction, being selected the surfactant derived from soy oil for this purpose. The values of the partition coefficients between the solid and liquid phases " D " for the studied metals varied from 0.2 to 1.1, while the coefficients for equilibrium model " K " varied from 0.0002 and 0.0009. The removal percentile for oil with all metals associated was near 100%, showing the efficiency of the process

Disponibilidade de metais pesados em Latossolo com aplicação superficial de escória, lama cal, lodos de esgoto e calcário

O objetivo deste trabalho foi avaliar alguns atributos químicos do solo e a disponibilidade de cádmio (Cd), cromo (Cr), níquel (Ni), mercúrio (Hg), chumbo (Pb) e arsênio (As), por meio da extração pelo DTPA, em conseqüência da aplicação superficial de escória de aciaria, lama cal e lodos de esgoto centrifugados e de biodigestores, nas doses 0 (testemunha), 2, 4 e 8 Mg ha-1 e um tratamento adicional composto pela calagem superficial na dose 2 Mg ha-1. O experimento foi conduzido em delineamento de blocos ao acaso, em condições de campo, em área sob sistema plantio direto, durante 2003 e 2004. A aplicação superficial de escória de aciaria, lama cal, lodo de esgoto centrifugado e de biodigestor, até a dose 8 Mg ha-1, assim como o calcário na dose 2 Mg ha-1, não trazem problemas de disponibilidade ao ambiente, com relação aos metais pesados Cd, Cr, Hg, Pb, Ni e As, quando aplicados sobre a superfície em Latossolo Vermelho distrófico, no sistema plantio direto. A fitodisponibilidade de metais pesados às culturas da soja e aveia-preta foi nula, quando foram aplicadas doses de até 8 Mg ha-1 de lodo de esgoto, escória e lama cal sobre a superfície do solo, no sistema plantio direto.

Extração de metais pesados de efluentes da indústria do petróleo utilizando derivados de óleos vegetais como extratantes

The study of a promising alternative for the treatment of produced water from the oil industry envisaging its reuse was the focus of this work. Millions of liters of water are generated per day, containing heavy metals in low concentrations (< 0,15 mg/L for Pb, <0,04 mg/L for Cd, <0,04 mg/L for Ni). The technology applied to extract these metals from aqueous phase was the solvent extraction and the extratants used were vegetable oils originated from coconut oil. They can be used in natural form or as derivatives, known as MAC - Mixture of Carboxílics Acids. The determination of the heavy metal con¬centrations in a complex matrix was made by using the atomic absorption spectrometry technique (AAS). On the bench tests using synthetics aqueous solutions containing metals, vegetable oils showed no power to extract the metals studied. The extractant MAC was selective for the Pb> Cd> Ni, in the concentration of 8% in the same organic phase. In this condition, the lower efficiency of extraction obtained was 92% for the Pb, 69% for the Cd, in the range of pH ranging from 6 to 8. An experimental planning was conducted for continuous tests. The device used was called MDIF Misturador-Decantador à Inversão de Fases and the aqueous phase was produced water from Pólo Indutrial de Guamaré/RN . No correlation between the studied variables (concentration of metal, concentration of extratant and agitation in the mixing chamer) could be obtained, because of possible factors which occurred as: variation in the composition of the studied sample, phenomena of precipitation and complexation of metals in the reservoir of feed, solubility of extratant
