Novas configurações de monopólios planares quase-fractais para sistemas de comunicações móveis

The characteristic properties of the fractal geometry have shown to be very useful for the construction of filters, frequency selective surfaces, synchronized circuits and antennas, enabling optimized solutions in many different commercial uses at microwaves frequency band. The fractal geometry is included in the technology of the microwave communication systems due to some interesting properties to the fabrication of compact devices, with higher performance in terms of bandwidth, as well as multiband behavior. This work describes the design, fabrication and measurement procedures for the Koch quasi-fractal monopoles, with 1 and 2 iteration levels, in order to investigate the bandwidth behavior of planar antennas, from the use of quasi-fractal elements printed on their rectangular patches. The electromagnetic effect produced by the variation of the fractal iterations and the miniaturization of the structures is analyzed. Moreover, a parametric study is performed to verify the bandwidth behavior, not only at the return loss but also in terms of SWR. Experimental results were obtained through the accomplishment of measurements with the aid of a vetorial network analyzer and compared to simulations performed using the Ansoft HFSS software. Finally, some proposals for future works are presented

Novas ferramentas para monitoramento ambiental usando SIG Web

The use of Geographic Information Systems (GIS) has becoming very important in fields where detailed and precise study of earth surface features is required. Applications in environmental protection are such an example that requires the use of GIS tools for analysis and decision by managers and enrolled community of protected areas. In this specific field, a challenge that remains is to build a GIS that can be dynamically fed with data, allowing researchers and other agents to recover actual and up to date information. In some cases, data is acquired in several ways and come from different sources. To solve this problem, some tools were implemented that includes a model for spatial data treatment on the Web. The research issues involved start with the feeding and processing of environmental control data collected in-loco as biotic and geological variables and finishes with the presentation of all information on theWeb. For this dynamic processing, it was developed some tools that make MapServer more flexible and dynamic, allowing data uploading by the proper users. Furthermore, it was also developed a module that uses interpolation to aiming spatial data analysis. A complex application that has validated this research is to feed the system with data coming from coral reef regions located in northeast of Brazil. The system was implemented using the best interactivity concept provided by the AJAX model and resulted in a substantial contribution for efficiently accessing information, being an essential mechanism for controlling events in the environmental monitoring

Novas alternativas de remoção de enxofre do óleo diesel utilizando tensoativos e microemulsões

The diesel combustion form sulfur oxides that can be discharged into the atmosphere as particulates and primary pollutants, SO2and SO3, causing great damage to the environment and to human health. These products can be transformed into acids in the combustion chamber, causing damage to the engines. The worldwide concern with a clean and healthy environment has led to more restrictive laws and regulations regulating the emission levels of pollutants in the air, establishing sulfur levels increasingly low on fuels. The conventional methods for sulfur removal from diesel are expensive and do not produce a zero-level sulfur fuel. This work aims to develop new methods of removing sulfur from commercial diesel using surfactants and microemulsion systems. Its main purpose is to create new technologies and add economic viability to the process. First, a preliminary study using as extracting agent a Winsor I microemulsion system with dodecyl ammonium chloride (DDACl) and nonyl phenol ethoxylated (RNX95) as surfactant was performed to choose the surfactant. The RNX95 was chosen to be used as surfactant in microemulsioned systems for adsorbent surface modification and as an extracting agent in liquid-liquid extraction. Vermiculite was evaluated as adsorbent. The microemulsion systems applied for vermiculite surface modification were composed by RNX95 (surfactant), n-butanol (cosurfactant), n-hexane (oil phase), and different aqueous phases, including: distilled water (aqueous phase),20ppm CaCl2solution, and 1500ppm CaCl2solution. Batch and column adsorption tests were carried out to estimate the ability of vermiculite to adsorb sulfur from diesel. It was used in the experiments a commercial diesel fuel with 1,233ppm initial sulfur concentration. The batch experiments were performed according to a factorial design (23). Two experimental sets were accomplished: the first one applying 1:2 vermiculite to diesel ratio and the second one using 1:5 vermiculite to diesel ratio. It was evaluated the effects of temperature (25°C and 60°C), concentration of CaCl2in the aqueous phase (20ppm and 1500ppm), and vermiculite granule size (65 and 100 mesh). The experimental response was the ability of vermiculite to adsorb sulfur. The best results for both 1:5 and 1:2 ratios were obtained using 60°C, 1500ppm CaCl2solution, and 65 mesh. The best adsorption capacities for 1:5 ratio and for 1:2 ratio were 4.24 mg sulfur/g adsorbent and 2.87 mg sulfur/g adsorbent, respectively. It was verified that the most significant factor was the concentration of the CaCl2 solution. Liquid-liquid extraction experiments were performed in two and six steps using the same surfactant to diesel ratio. It was obtained 46.8% sulfur removal in two-step experiment and 73.15% in six-step one. An alternative study, for comparison purposes, was made using bentonite and diatomite asadsorbents. The batch experiments were done using microemulsion systems with the same aqueous phases evaluated in vermiculite study and also 20ppm and 1500 ppm BaCl2 solutions. For bentonite, the best adsorption capacity was 7.53mg sulfur/g adsorbent with distilled water as aqueous phase of the microemulsion system and for diatomite the best result was 17.04 mg sulfur/g adsorbent using a 20ppm CaCl2solution. The accomplishment of this study allowed us to conclude that, among the alternatives tested, the adsorption process using adsorbents modified by microemulsion systems was considered the best process for sulfur removal from diesel fuel. The optimization and scale upof the process constitutes a viable alternative to achieve the needs of the market

Produção de sentidos sobre a maternidade: uma experiência no Programa Mãe Canguru

Este artigo analisa, sob a perspectiva da relação entre a família e instituições de saúde, os sentidos produzidos sobre a maternidade em um programa de saúde neonatal desenvolvido na rede pública - o Programa Mãe Canguru. A partir de entrevistas e observações feitas com usuárias durante sua participação no programa, buscamos apreender como as práticas discursivas e não discursivas sobre maternidade e maternagem, difundidas nesse processo, se articulam com as experiências concretas dessas mulheres para produzir novas configurações subjetivas. Na interpretação dos dados, realizada através de análise do discurso, os aspectos mais significativos das falas das entrevistadas foram agrupados em quatro núcleos de sentido: família e religião; o impacto do nascimento prematuro; desconfiança e resistência nas relações com instituições e profissionais de saúde; e a experiência com o Programa Mãe Canguru. Ao final, procurou-se identificar as principais estratégias e formas de singularização utilizadas por essas mulheres ao atribuírem sentidos ao papel materno.

Apropriação de novas mídias por estudantes universitárias

It is an investigation that seeks to reveal, record and analyze the process of appropriation and use of digital media by university students, aged between 40 and 60 years. Interested in studying how changes are perceived in the educational sphere for students Whois have gone through liberal/traditional school, ie, effected the first contact with technological devices media as adults, in the university. This investigation sought to contribute to the knowledge on the use of new learning strategies imposed by digital media by recording and analyzing the reports surveyed sample. Allowed to know the cultural universe of these women, revealing the context in which receive mediated messages and uses that maré these learning strategies within their daily academic life. Gathered in this work, reflexions guided by studies of media reception and role played by digital media as builders images and facilitators in knowledging acquisitions, it was chosen to work two main theorical notions: communication media and digital inclusion. As the research methodology, it was used the exploratory descriptive technical together with other appropriate tecniques. In ordem to approach the problem can be observed two phases: a quantitative one, which was used an investigative procedure, a survey data with closed questions; and a qualitative phase, which was used to collect data through a diary from situations encountered in the classroom. The main objective of analyzing how digital media are received, appropriated and used by university women has been fulfilled and it is remarkable that they access with dificulty and can not be considered included digitally. The results show that the problem of these agents is not the access, there are was of appropriation of digital media offered at IES, and it was possible to note that they seek to integrate to the technological world, and they even have devices that can insert them on this world. Insertion in cyberculture sets up the ability to find a favorable way to be aware of reality and production of knowledge and liberating and dignifying practices, in this case refers to an appropriation of citizenship through the field of technological devices offered as a perspective that they can interact

Variação temporal e descrição de novas espécies de collembola (arthropoda, hexapoda) em uma área de caatinga do nordeste do Brasil

Collembola is one of the most abundant and diverse group of terrestrial arthropods, being at the base of the food chain operating in the decomposition process. They have a wide distribution in the world and can be found in practically all habitats. The knowledge of this distinctive fauna is still deficient in brazilian territory, especially in semi-arid region. The aim of this study was to investigate which climatic variables may act as predictors of species richness, abundance of individuals and compositional structure of the taxocenose of Collembola over 12 months in an area dominated by semi-arid Caatinga vegetation, northeastern Brazil and describe new species of the genus Seira found, more diverse taxon of Collembola in Brazil. Samples were collected in João Câmara, Rio Grande do Norte. Ten plots of 20 x 20 meters were established and the specimens were collected with collection effort of one hour/people using entomological aspirator. The identification and description of the species was carried out by studying the morphology and chaetotaxy. Was performed a multiple regression analysis between species richness and abundance of individuals with climatic variables. A total of 1231 individuals belonging to 15 species, 12 genera and nine families. The greatest richness and abundance of Collembola were found during the rainy season. The genus Seira was the most abundant. Rainfall explained the temporal variation in species richness and abundance of Collembola in the semi-arid region, which is consistent with the biology of these animals. The populations of Collembola showed grouped distribution. Three new species of Seira were described and illustrated and all show similarities with species already registered in the national territory

Novas formulações de fluidos de corte: otimização, propriedades e recuperação do óleo usado

Cutting fluids are lubricants used in metal-mechanical industries. Their complex composition varies according to the type of operation carried out, also depending on the metals under treatment or investigation. Due to the high amount of mineral oil produced in Northeastern Brazil, we have detected the need to better use this class of material. In this work, two novel formulations have been tested, both based on naphthenic mineral oil and additives, such as: an emulsifying agent (A), an anticorrosion agent (B), a biocide (C) and an antifoam agent (D). Each formulation was prepared by mixing the additives in the mineral oil at a 700-rpm stirring velocity for 10 min, at 25°C, employing a 24 factorial planning. The formulations were characterized by means of density, total acid number (TAN), viscosity, flash point and anticorrosion activity. In a subsequent study, oil-in-water emulsions were prepared from these novel formulations. The emulsions were analyzed in terms of stability, corrosion degree, percentage of foam formation, conductivity, accelerated stability and particle size. The samples were appropriately labeled, and, in special, two of them were selected for featuring emulsion properties which were closer to those of the standards chosen as references (commercial cutting oils). Investigations were undertaken on the ability of NaCl and CaCl2 to destabilize the emulsions, at concentrations of 2%, 5% and 10%, at an 800-rpm stirring velocity for 5 min and temperatures of 25º, 40º, 50º and 60ºC. The recovered oils were chemically altered by reincorporating the same additives used in the original formulations, followed by preparation of emulsions with the same concentrations as those of the initial ones. The purpose was to assess the possibility of reusing the recovered oil. The effluents generated during the emulsion destabilization step were characterized via turbidity index, contents of oil and grease, pH, and contents of anions and cations, observing compliance with the parameters established by the current environmental legislation (Brazil s CONAMA 357/05 resolution). It could be concluded that the formulations presented excellent physicochemical properties as compared to commercial cutting fluids, showing that the quality of the newly-prepared fluids is superior to that of the formulations available in the market, enabling technically and environmentally-safe applications

Contribuição da teoria do caos para a gestão do turismo: uma análise a partir da percepção dos gestores da hotelaria de Natal/RN

O presente estudo tem como objetivo analisar como os gestores da hotelaria percebem a relação da teoria do caos e turismo, descrever como é pensada e concebida a gestão do turismo; mostrar as características caopléxicas do turismo e sua gestão e identificar os elementos do padrão estratégico de gestão e planejamento na visão dos gestores dos Meios de Hospedagem. Os dados foram obtidos através da observação direta intensiva e aplicação de entrevistas aplicadas junto aos hoteleiros da cidade de Natal/RN. Constata que as teorias da mudança e do caos proporcionam visão do conjunto de relações, aspectos e implicações do turismo, com base nas incertezas e instabilidades ambientais e de mercado. Mostra que a maioria dos modelos de análise, planejamento e gestão do turismo ainda é limitada, em razão do seu caráter linear e unidimensional. Destaca que o objetivo da teoria do caos é fornecer explicações dos fenômenos, não é fazer previsões, pois é impossível prever o futuro a longo prazo. Trata das estratégias de gestão como geradoras de novas fontes de incerteza, pois a realidade não pode ser completamente representada por modelos. Ter consciência desses fatos significa, entretanto, considerar o campo de múltiplas possibilidades e oportunidades da mudança e do caos na gestão do desenvolvimento do turismo. Essas idéias foram aplicadas à análise da gestão do turismo na localidade investigada. Os questionamentos levantados no estudo pautaram-se em pesquisa bibliográfica, fundamentada, principalmente, em autores como Beni, Prahalad, Mintzberg, Ritto, Senge e Hamel. Conclui-se que na era do conhecimento, as organizações que continuam presas ao paradigma mecanicista têm dificuldade de acompanhar as mudanças do mercado e sendo a hotelaria uma indústria de serviços que tem características organizacionais complexas e adaptativas, é imprescindível que os empreendimentos hoteleiros funcionem como sistemas interativos, que acompanhem as mudanças de um mercado tão turbulento e instável tendo na teoria do caos e da complexidade uma das possibilidades de compreender a realidade fora do modelo mecanicista.

Determinantes de competitividade de destinos turísticos aplicados aos roteiros regionais: uma avaliação do roteiro Seridó/RN

The tourism industry is gaining representation by move and stimulate the economy, especially by allowing the generation of employment and income, thus allowing growth opportunities for localities where tourism develops. Therefore, the present study entitled determinants of competitiveness of tourist destinations applied to regional routes: an evaluation of the Route of Seridó/RN, discusses the issue of competitiveness in tourism and tries to understand the scenery of this Route. The main objective of the study is to assess the conditions of competitiveness in the Route of Seridó/RN according to benchmarks and global determinants of competitiveness for tourist destinations. The study has also as specifics objectives: define dimensions of the reference model for use in evaluating the competitiveness of the Route of Seridó/RN; identify levels of governance and competitiveness in the municipalities that make up the sample set above the Route, and analyze to what extent the competitiveness of the Route correspond to the global reference of competitiveness of tourism destinations. Regarding the methodology, it is a search for an exploratory- descriptive and used a combination of quantitative and qualitative research method as expected and required in the implementation of the evaluation tool called Compet&enible Model. For data collection, it has been taken technical visits and also analysis of documents and materials. Data analysis was based on the records and documents and the use of simple descriptive statistics for the scores of the elements offered by Compet&enible Model. The results allowed us to know the real conditions of competitiveness of the Seridó/RN Route forward to the attributes of tourist destinations for global competitiveness: the dimension I, Governance, reached 17 points, classified as "in structuring" and dimension II, Competitiveness, reached 10 points, ranking "weak". These results highlight the need for greater involvement of the actors in the supply chain of tourism in Polo Seridó/RN for the actions, programs and projects are put into practice. It is expected that tourism is considered an important activity for the local and global development, serving as a reference for the future management of Seridó/RN Route, guiding new policy guidelines, planning and organization to better competitiveness

Ação de impugnação de mandato eletivo: análise constitucional e novas perspectivas

This study is developed in setting in which the Federal Constitution of 1988 completed 22 years of validity, as well as in general elections (national and state) in country. From this perspective, there are multiple reflections, especially on the constitutional mechanisms of popular sovereignty consolidation, the integrity and legitimacy of elections and democracy itself. It has appeared timely, therefore, to examine the development of ensured instrument of these precepts. Thus, it is approached as an object of research to Action of Impugnation to the Elective Mandate- AIEM, under Art.14, § 10 and § 11 of the Constitution of 1988, considering its constitutional and electoral reasons. It is then aimed to review the second AIEM conceptions of scale, systematic interpretation, preservation of constitutional rights and its effectiveness. Specifically, it is analyzed the Action as to the forms of power that relate to this. then it is examined the democracy principal aspects related to the issue. Without being followed, it is the democratic situation in which it is operated. They are also examined the political rights, especially regarding restraint applied to ineligibility and the possibility of integrating the effects of an impugnatory origin. Following, it has been discussed the formation of an early panorama, consisting of constitutional principles applied to electoral constituencies and eminently procedural principles and, according to which subsidizes the operations of such Action. After that, addressing the Election Law, including its concept, its sources, the Electoral Court and its peculiarities and functions. It is also considered the elective office as to its definition, characteristics and ways of accessing and extinguishing it. Afterwards, the Action of Impugnation is studied from its historical evolution of laws, legal, concept and goals. Expanding on the theme, it s highlighted about their chances of traditional appropriateness (economic power abuse, corruption and fraud) and modern (abuse of economic power intertwined with political) business, including the suggestion of suitability in case of abuse of unique political power. It was also identified the injurious potential demand affecting these illicit to enable the Action. Subsequently, other relevant aspects were explored, such as the legitimacy ad causam, competence, secrecy, procedure, recklessness, bad faith, the purpose of the merits and manageable resources. In the end, it is demonstrated an evolution of AIEM, however, still insufficient to reach full intentions that rise it. It is proposed therefore to re-read the action from news perspectives, based on constitutional and electoral precepts, as well as wider interpretation of the appropriateness of their assumptions of suitability and effects, according to a systematic interpretation, all aimed at the preservation of constitutional rights and their own effectiveness

O ensino da língua portuguesa na televisão: uma análise através do programa afinando a língua

The present dissertation aims to an approach of the teaching of Portuguese language on television, trying to find how possible is the contribution of this communication media in the sense to give a higher classroom dynamism and to excite the students for that subject. The TV show Afinando a Língua (roughly, putting the language in tune ), a Canal Futura feature, have as one of these main purpose be shown on the classrooms as a tool that could enlarge the possibilities of a subject often took as particularly difficult. Blocked by the traditional grammatical teaching, the Portuguese lessons have been for years pictured as hermetic and far from the Brazilian speakers reality. So, people create myths around the language that earns adjectives as complicate and inaccessible and that Brazilians can t speak the Portuguese really good, because it only happens in Portugal, the original country of the language. These myths start exactly because the teaching orientation take their basis only on the standard language, in fact just one of the language variations by the way, anywhere in the world dictated by ancestral rules, once produced in Portugal. The regular school don t accept the Portuguese variation as a natural fact for a huge country as Brazil, with almost 190 million people, regarding it as a wrong way of talking. The repression that follows the students from the early school days make them repel the language supposedly learned at school. In fact, they normally face it as something unfamiliar, different from the language that they have use to learn at home, from the family and neighbors Instead of giving new possibilities for the language learning, the television, a powerful audiovisual device, only reinforces the idea that everyone, in any life situation, should talk the standard Portuguese, turning its back to the learning acquired much earlier that any person reach the school. This conservative attitude brings almost no changes, between the shows that try to teach the idiom and the traditional Portuguese lessons, wasting valuable tools that could lead to the possibility to open the classroom to the outside world, and to the wider knowledge of the differences from each Brazilian region culture, a positive attitude that could much enlarge the cultural and linguistic students universe

Saberes docentes, alfabetização, respeito à infância: a criança de 6 anos no ensino fundamental

Éste trabajo se inserta en el ámbito de los cambios en la Enseñanza Fundamental (EF) brasileño que, por la Ley Federal n.º 11.114/2005 anticipa el EF para seis años de edad, y de la Ley n.º 11.274/2006 que amplia el mismo nivel de enseñanza de ocho para nueve años Tales cambios tienen sido respaldados por el argumento de la importancia de se anticipar y promover un mayor acceso a la educación y garantizar una permanencia bien sucedida del alumno en la etapa obligatoria de la Educación Básica. La inclusión de los niños de seis años en el EF puede ser considerada una conquista en el ámbito de las políticas públicas brasileñas destinadas a la educación de niños. Sin embargo, la sencilla simples anticipación/ampliación de matrículas en el EF puede constituirse en más una forma de exclusión, si no fueren garantizadas las condiciones necesarias para se ofrecer una educación de calidad que considere las peculiaridades de una práctica pedagógica de alfabetización con niños más jóvenes. Evidentemente, muchos son los factores que pueden influenciar la calidad de la educación y el tratamiento escolar financiamiento, gestión, organización del espacio escolar pero la acción del profesor, en ése sentido, es un factor primordial entre otros determinantes. Así pensando, definimos como objetivo de éste trabajo investigar saberes docentes requeridos de el profesor para el desarollo de una práctica pedagógica que tiene por meta la apropiación de la lengua escrita, por el niño de seis años recién-ingresa en la Enseñanza Fundamental respetando su condición de ser niño . Para tanto, en el ámbito del enfoque cualitativo de la encusta, realizamos un estudio de caso en dos instituciones públicas: Escola Municipal Professora Emilia Ramos y Centro Municipal de Educação Infantil Marise Paiva, ambas ubicadas en la Zona Este en la ciudad de Natal. De la análisis del contenido de los datos, emergió la temática Saberes Docentes para la Alfabetización de Niños de seis años en la Enseñanza Fundamental que, a la vez, cubre dos categorías de saberes, con suyas respectivas subcategorías: Saberes Docentes Transversales a las Práctica Pedagógica de Alfabetización y Saberes Docentes Específicos a la Práctica Pedagógica de Alfabetización. Entre tantos aprendizaje proporcionadas por el estudio, comprendemos que, sea en la Educação Infantil, sea en la Enseñanza Fundamental, el trabajo con el niño no debe constituirse en la negación de su infancia. Sin embargo, en se tratando de el EF, el esfuerzo para no desvirtuar la voluntad política de proporcionar al niño oportunidades de alfabetización debe ser redoblado, una vez que ésa etapa de la educación podrá ser la marca de un rico y agradable proceso de alfabetización, como puede ser motivo para que el niño se torne desinteresado y acobardado para aprender a leer y a escribir, si no fueren respetadas las necesidades y especificidades propias de ése momento de su desarollo. El estudio también ratificó nuestra comprensión de que la Alfabetización es un proceso peculiar, no constituyéndose, por lo tanto, en tarea simple para el docente, ni tampoco para el niño, visto que la lengua escrita, por si misma, ya es un objeto de estudio bastante complejo. Comprendemos, sin embargo, que esa complejidad no puede tornarse obstáculo para que, también en la escuela pública, ya a los seis años, se permita al niño un trabajo de calidad que tiene por meta su alfabetización, hasta porque, mientras participantes de una sociedad letrada, antes de ingresar a la escuela, los niños ya construyeran concepciones previas sobre la lectura y la escrita, a las cuales el profesor debe estar muy atento

Da compreensão novas viagens de Gulliver

Ayant comme opérateur cognitif le livre Les Voyages de Gulliver, de Jonathan Swift, la thése, écrite au format d'un journal de bord, suit dévoilant des indices pour une archéologie de la compréhension, au-delà de problématiser les interconexions entre communication et compréhension à l'actuel procés de planétarism. En suite, réalise quelques essais qui problématisent l'éthique, la science, et la condition humaine, sous l'inspiration du Parlément des Choses, suggéreé par Bruno Latour, où sont présents, symétriquement, les sciences, les scientists, les politiques, les natures, les cultures, et les sociétés. Pour une telle aventure, sont agencées des ideas de penseurs de diverses domaines de la connaissance, comme Edgar Morin, Henri Atlan, Hans-Georg Gadamer, Isabelle Stengers, David Bohm, Maria da Conceição de Almeida, Cremilda Medina, María Zambrano, Michel Serres, Boris Cyrulnik, dentre autres. Lettres de musique, registres littéraires et cinématographiques servent de points d'appuy pour la contextualization du récit de ce voyage qui ne comporte pas seulement la compréhension de la compléxité de l'être-humain, mais aussi, la compréhension des conditions dans lequelles sont forgées les mentalités et pratiques les actions. Ainsi, toule compréhension est un voyage sans fin: arrive à quelques ports, se ré-approvisionne et part à nouveau. Toute compréhension est ponctuelle, parcielle, provisoire, lacunaire et inachevée.
