Viabilidade da geração de eletricidade a partir de fonte eólica on-shore: dificuldades e vantagens de expansão na matriz elétrica brasileira

The renewable energy sources presents an important role on the world's current context, its growing is essentially connected to the environmental issues and the energetic security, guided by the search for alternatives of energy. Among the alternative energy sources, the wind energy shows great importance in the brazilian territory, it has a great potential still unexplored and constant growth in the national electric matrix. The specific factor of generation, the conjuncture and the incentive politics influence on the expansion of wind energy in Brazil. Thus, the brazilian wind sector shows features which can be evaluated enable its developing. Keeping that in mind, the present work aims identify which are the advantages and the difficulties for the expansion of this energy source in the brazilian electric matrix. For that, the work studies the different parameters: features of electric generation of the different energy sources, incentive politics, generation costs, CO2 emission, evolution of wind energy in Brazil, the brazilian wind potential, and the regime of complementarily hydro-wind

Concepções sobre escola e gênero na perspectiva de crianças abrigadas

School and family are critical contexts to the development of concepts in childhood and few studies are conducted from the report of children when they live in rest-home. The aim of this study was to investigate concepts that children in rest-homes have about school and gender. There were 22 participants, including boys and girls, between 4 and 6 years, who were interviewed with open questions for content analysis. For these children the school was associated with an area of study opportunities, favorable to themselves, although by necessity or obligation, and possibly with the presence of conflicts. The gender was described from biological and psychosocial aspects and children attributed their gender identity at destination, learning and social advantages. Children feel they belong to a gender in a positive way, although by attributing disadvantages to the opposite gender, for example, relating male aggression to violence. Children reproduce some patterns and social characteristics of gender that probably were learned in different contexts. We conclude that studies in this area are important to identify children´s conceptions about school and sexuality, their roles and representations, especially when they live in an environment with such specific features as a rest-home.

Preparação e caracterização óptica de filmes híbridos dopados com o azocorante Disperse Red 1

The Sol-gel process has facilitated the processing of Organic-Inorganic Hybrid Materials with several scientific applications and technologies. The hybrid combine the advantages of the Sol-gel process with specific characteristics of organic polymers, allowing processing of thin films without fractures or fissures. The incorporation of azo dyes in polymer matrices has been widely used in the investigation of optical properties. The azo dye Disperse Red (DR1) presents optical alterations when exposed to visible or ultraviolet light. The alterations occur due to transitions of their isomers, trans and cis, caused by photoisomerization, due to electronic transitions of azo group (-N=N-), presenting photochromic and/or photorefractive effects. The hybrid system used in this work is the precursor 3- Glycidoxypropyl-Trimethoxi-silane (GPTS), the Tetraethylorthosilicate (TEOS) and DR1 as a dopant. The characterizations were performed using absorption spectroscopy UV-Vis which allowed the identification of the absorption bands and its variations when the samples were treated thermally and/or illuminated by ultraviolet light

Storage media for avulsed teeth: a literature review

Dental avulsion is the most severe type of traumatic tooth injuries because it causes damageto several structures and results in the complete displacement of the tooth from its socketin the alveolar bone. The ideal situation is to replant an exarticulated tooth immediatelyafter avulsion because the extraoral time is a determinant factor for treatment successand for a good prognosis. However, it is not always possible. The success of replantationdepends on a number of factors that may contribute to accelerate or minimize theoccurrence of root resorption or ankylosis, among which is the type and characteristicsof the medium used for temporary storage during the time elapsed between avulsionand replantation. Maintaining the tooth in an adequate wet medium that can preserve,as longer as possible, the vitality of the periodontal ligament cells that remain on rootsurface is the key to success of replantation. Recent research has led to the developmentof storage media that produce conditions that closely resemble the original socketenvironment, with adequate osmolality (cell pressure), pH, nutritional metabolites andglucose, and thus create the best possible conditions for storage. Although these storagemedia can now be purchased in the form of retail products, the most common scenariois that such a product will not be readily available at the moment of the accident Thispaper reviews the literature on the different storage media that have been investigatedfor avulsed teeth based on full-length papers retrieved from PubMed/Medline, Lilacs, BBOand SciELO electronic databases using the key words storage medium , transportationmedium , avulsion , tooth avulsion , replantation , tooth replantation , milk and propolis .After application of inclusion and exclusion criteria, 39 papers were selected and criticallyreviewed with respect to the characteristics, efficacy and ease of access of the storagemedium.

Tomografia computadorizada Cone Beam em Ortodontia - evolução ou revolução? visão geral, aplicações, vantagens/desvantagens e dose de radiação

Introduction: The request of three-dimensional images (3D) of the dentomaxillofacial complex has increased. Hence, new possibilities for assessment, treatment as well as follow-up after treatment have increased their importance with the use of cone beam computed tomography (CBCT). The images in two dimensions (2D) have inherent problems that can be solved with treedimensional images assessment. Objectives: To clarify the main doubts about the operational mechanism of complementary diagnostic method; to explain the advantages and disadvantages, to discuss the effective radiation dose and possible applications in orthodontia. Conclusion: The information generated by 2D images from the CBCT does not show differences that may endanger the orthodontic planning when compared with the images of 2D conventional radiographs. The effective radiation dose received by the patient should not be considered as a limiting factor of the tomography exam request.

Análise da viabilidade do uso de biogás gerado a partir de dejetos bovinos em microturbinas para fins de geração, cogeração e trigeração de energia

The use of digesters has become an important alternative for the proper disposal of organic agricultural wastes, serving as a solution to some environmental and health problems. Furthermore, the process of digestion provides commercially valuable by products such as biogas and bio fertilizer. The generation of biogas from agricultural waste, and its use in power generation systems has aroused great interest in rural areas because it enables supply in whole or in large part the energy demand of ownership by reducing production costs. The advent of technology has brought new forms of energy conversion of biogas, as the use of micro turbines specifies to be fuelled with biogas derived from the decomposition of organic matter in digesters, since it has a low level of methane in its composition, and high degree of impurities such as hydrogen sulphide, which are harmful to equipment and reduce the calorific value of biogas. The use of micro turbines behind other advantages like low emissions, great fuel flexibility and low maintenance. This paper presents an analysis of the feasibility of using biogas generated from cattle manure in micro turbines to generate electricity. Behind also an assessment of the energy potential that each animal has on various uses of biogas, and forms of energy recovery from the exhaust gases of the micro turbine. Also conducts an evaluation of the energy savings that the use of biogas aggregates properties.

É possível predizer o tempo de terapia das alterações específicas no desenvolvimento da linguagem?

OBJETIVO: Explorar quais medidas poderiam predizer a persistência de alterações específicas no desenvolvimento da linguagem (AEDL) a partir da associação entre os dados do desempenho na primeira avaliação fonoaudiológica e do prognóstico terapêutico da criança. MÉTODOS: Neste estudo retrospectivo, foram analisados 42 prontuários pertencentes a crianças com diagnóstico de AEDL. As idades variavam entre 21 e 63 meses no momento da primeira avaliação fonoaudiológica, que incluiu as provas de vocabulário, fonologia, pragmática e fluência. O desempenho dos sujeitos em cada prova foi pontuado de 0 a 4, com base na gravidade das alterações, sendo a pontuação máxima a adequada para a idade. Como medida prognóstica, contabilizamos o tempo de terapia (em sessões) dos pacientes que receberam alta, foram encaminhados (o quadro havia se tornado muito leve), ou permaneceram em terapia (dificuldades persistentes de linguagem). RESULTADOS: Houve associação entre os dados da avaliação inicial (classificação normal ou levemente alterada no vocabulário e pragmática) e o prognóstico (<135 sessões terapêuticas). A variável referente ao vocabulário foi a única capaz de predizer o tempo de terapia. A classificação como grave nesta medida aumentou, em média, 112 sessões na estimativa do tratamento. CONCLUSÃO: A primeira avaliação do vocabulário pode contribuir para predizer o prognóstico terapêutico da criança. Este achado é de relevância clínica e científica para a Fonoaudiologia, visto que oferece um recurso auxiliar para a realização do prognóstico e planejamento terapêutico nos quadros de AEDL.
