Ferroelectric ceramics with perovskite structure (ABO3) are widely used in solid state memories (FeRAM’s and DRAM's) as well as multilayered capacitors, especially as a thin films. When doped with zirconium ions, BaTiO3-based materials form a solid solution known as barium zirconate titanate (BaTi1-xZrxO3). Also called BZT, this material can undergo significant changes in their electrical properties for a small variation of zirconium content in the crystal lattice. The present work is the study of the effects of deposition parameters of BaTi0,75Zr0,25O3 thin films by spin-coating method on their morphology and physical properties, through an experimental design of the Box-Behnken type. The resin used in the process has been synthesized by the polymeric precursor method (Pechini) and subsequently split into three portions each of which has its viscosity adjusted to 10, 20 and 30 mPa∙s by means of a rotary viscometer. The resins were then deposited on Pt/Ti/SiO2/Si substrates by spin-coating method on 15 different combinations of viscosity, spin speed (3000, 5500 and 8000 rpm) and the number of deposited layers (5, 8 and 11 layers) and then calcined at 800 ° C for 1 h. The phase composition of the films was analyzed by X-ray diffraction (XRD) and indexed with the JCPDS 36-0019. Surface morphology and grain size were observed by atomic force microscopy (AFM) indicating uniform films and average grain size around 40 nm. Images of the cross section of the films were obtained by scanning electron microscopy field emission (SEM-FEG), indicating very uniform thicknesses ranging from 140-700 nm between samples. Capacitance measurements were performed at room temperature using an impedance analyzer. The films presented dielectric constant values of 55-305 at 100kHz and low dielectric loss. The design indicated no significant interaction effects between the deposition parameters on the thickness of the films. The response surface methodology enabled better observes the simultaneous effect of variables.

We present the results of electrical resistivity, magnetic susceptibility, specific heat and x-ray absorption spectroscopy measurements in Tb1−xYxRhIn5 (x = 0.00, 0.15, 0.4.0, 0.50 e 0.70) single crystals. Tb1−xYxRhIn5 is an antiferromagnetic AFM compound with ordering temperature TN ≈ 46 K, the higher TN within the RRhIn5 serie (R : rare earth). We evaluate the physical properties evolution and the supression of the AFM state considering doping and Crystalline Electric Field (CEF) effects on magnetic exchange interaction between Tb3+ magnetic ions. CEF acts like a perturbation potential, breaking the (2J + 1) multiplet s degeneracy. Also, we studied linear-polarization-dependent soft x-ray absorption at Tb M4 and M5 edges to validate X-ray Absorption Spectroscopy as a complementary technique in determining the rare earth CEF ground state. Samples were grown by the indium excess flux and the experimental data (magnetic susceptibility and specific heat) were adjusted with a mean field model that takes account magnetic exchange interaction between first neighbors and CEF effects. XAS experiments were carried on Total Electron Yield mode at Laborat´onio Nacional de Luz S´ıncrotron, Campinas. We measured X-ray absorption at Tb M4,5 edges with incident polarized X-ray beam parallel and perpendicular to c-axis (E || c e E ⊥ c). The mean field model simulates the mean behavior of the whole system and, due to many independent parameters, gives a non unique CEF scheme. XAS is site- and elemental- specific technique and gained the scientific community s attention as complementary technique in determining CEF ground state in rare earth based compounds. In this work we wil discuss the non conclusive results of XAS technique in TbRhIn5 compounds.

The number of overweight people has increased in the last few years. Factors such as attention to diet and changes in lifestyle are crucial in the prevention and control of obesity and diseases related to it. Experts believe that such actions are most effective when initiated during childhood, and that children raised in an environment that encourages physical activity ultimately become healthier adults. However, to arouse and maintain interest in such activities represent a major challenge, which are initially perceived as repetitive and boring, and, thus, soon abandoned. Computer games, traditionally seen as stimulants to a sedentary lifestyle are changing this perception using non-conventional controls that require constant movement of the player. Applications that combine the playfulness of such games to physical activity through devices, like Microsoft Kinect, might become interesting tools in this scenario, by using the familiarity of Natural User Interfaces along with the challenge and the fun of video games, in order to make attractive exercise routines for schoolchildren. The project carried out consists of an exergame composed of several activities designed and implemented with the participation of a Physical Educator, aimed at children between eight and ten years old, whose performance and progress can be remotely monitored by a professional via web interface. The application arising from this work was accompanied by tests with a group of graduating Physical Education students from the University of Rio Verde GO, and subsequently validated through questionnaires whose results are shown on this work.

O uso das mídias sociais digitais como meio de divulgação de produtos, serviços e conteúdos organizacionais tem crescido nas últimas décadas e ganhou especial atenção nos planejamentos de comunicação organizacional e nos estudos acadêmicos sobre o tema. Nesse sentido, o segmento de empresas esportivas atua com destaque, despertando o interesse e a empatia do consumidor. Por meio de análise bibliográfica e estudo empírico, esta pesquisa teve como objetivo investigar as ações de comunicação mercadológica do segmento esportivo no ambiente digital conectado, através de um estudo de caso múltiplo das empresas Nike e Adidas. Para a obtenção dos dados, foram realizadas entrevistas em profundidade com profissionais do mercado e aplicado um protocolo de investigação de redes sociais digitais nos perfis das duas empresas. Após a coleta dos dados, estes foram analisados à luz das teorias estudadas nos capítulos iniciais (que abordaram temas como comunicação organizacional, comunicação digital, esporte e comunicação esportiva), e foi possível concluir, entre outros pontos, que, no universo do segmento esportivo, a comunicação digital conectada não prioriza o diálogo com seus públicos de interesse, sendo essencialmente baseada na divulgação unilateral de conteúdos, nem tampouco explora a potencialidade de cada uma das plataformas digitais disponíveis, replicando conteúdos em diferentes ambientes. Ficou evidente, também, o uso dos elementos constituintes do universo esportivo como argumentos estratégicos de comunicação das empresas, decorrente de sua capacidade de estreitar os laços relacionais com os públicos de interesse, por meio de seus apelos simbólicos de fácil identificação social.

Advances related to information technology are visible and inherent to the management of contemporary organizations, regardless of industrial action. Synchronized with this dynamic, educational institutions are incorporating technological tools that assist its management and academic support to teachers in teaching and interaction with the students. Given that technological innovations are not always taken homogeneously and with the same degree of coverage, remain current and relevant studies on how these technologies are being used in academia. The objective of this research is to identify the usage profile of the functionality of a virtual learning environment related to teaching (undergraduate or postgraduate), demographic variables (age and gender) and institutional (time of admission and academic center of origin.) The methodology applied to the study is descriptive and quantitative. The research is characterized as census, covering all 2152 teachers of undergraduate and graduate students of the Federal University of Rio Grande do Norte, Brazil, who accessed the virtual classes of the Integrated Management of Academic Activities. The study findings revealed that there is a statistically significant difference regarding the use of these tools to teachers who work with undergraduate (49.3%) compared to graduate (6.6%). Regarding gender, women (40.1%) use the system more than men (38.5%). It was also observed that the younger teachers, aged 37 years, are the most active users (42.5%) of the Virtual Class with respect to their elders. For teachers with up to three years time of admission to the UFRN, the pattern of use is more advanced than those with more seniority, as well as the faculty of the Center for Science and Technology are the least likely to use the tools available in relation to other academic centers. It is hoped that with this study managers can direct actions to improve and expand the use of this environment by teachers

Este artigo tem como objetivo mostrar que é possível incentivar a aprendizagem em museus através da construção de comunidades virtuais, com base em repositórios de objetos de aprendizagem (OA), ferramentas comunicacionais e produção de OA por parte dos visitantes. O enfoque é incentivar a aprendizagem no sentido de motivar a participação/envolvimento do visitante nas atividades da comunidade virtual. Nesta perspectiva, partimos do pressuposto de que a informação, a comunicação, a interação e a colaboração são essenciais para o processo de aprender no contexto informal dos museus. Acreditamos que a interação e a colaboração são partes integrantes do processo de aprendizagem proporcionado por comunidades virtuais e que o principal recurso de aprendizagem oferecido nessas comunidades são os objetos de aprendizagem. Assim sendo, por meio de um entendimento do aprender baseado na comunicação e na linguagem, percebemos os museus interativos como espaços discursivos em que os visitantes mergulham e por eles são modificados. Neste sentido, argumentamos que as comunidades virtuais de aprendizagem, com a possibilidade de virtualizar a linguagem, são excelentes mecanismos para ampliar o poder comunicacional dos museus, criando novas estratégias comunicativas. Para atingir o objetivo, foi necessário reunir quatro conceitos técnicos da área de informática, são eles: comunidades virtuais de aprendizagem; objetos de aprendizagem; metadados e mapas de tópicos. A junção destes conceitos permitiu a construção do ambiente de comunidade virtual, denominada CV-Muzar. Diante do exposto, de modo a identificar os meios pelos quais se podem motivar os visitantes a realmente produzirem novos conhecimentos durante sua visita informal ao museu, examinando essa questão tanto do ponto de vista quantitativo, como também qualitativamente, foi realizada uma experimentação do ambiente com um grupo de pessoas convidadas segundo suas áreas de formação.

Introdução: No contexto dos avanços tecnológicos incorporados ao ensino, os objetos e os ambientes virtuais de aprendizagem constituem ferramentas de apoio ao ensino colaborativo e interativo cada vez mais desenvolvidas (Aguiar, 2011; Alencar, 2012). A fim de nortear o desenvolvimento e validação destes relevantes instrumentos educacionais, verifica-se a necessidade de conhecer os conceitos que nortearam o seu desenvolvimento e identificar suas origens e aplicações, o que pode favorecer a uniformização do uso e significado pelos pesquisadores nas diversas áreas do conhecimento. Objetivos: Analisar o conceito de objeto e de ambiente virtual de aprendizagem na perspetiva evolucionária de Rodgers. Metodologia: Estudo descritivo, de abordagem mista, realizado a partir das etapas propostas por Rodgers (2000) em seu modelo de análise conceitual. A coleta de dados ocorreu em agosto de 2015 com a busca de dissertações e teses no Banco de Teses e Dissertações da Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), Brasil. Os dados quantitativos foram analisados a partir de estatística descritiva simples e os conceitos através de análise lexicográfica com suporte do software Interface de R pour Analyses Multidimensionnelles de Textes et de Questionneires (IRAMUTEQ). Resultados: A amostra é constituída por 161 estudos, onde predominaram os decorrentes de mestrado acadêmico (67,1%). O conceito "ambiente virtual de aprendizagem" (AVA) foi apresentado em 99 (61,5%) estudos, enquanto "objeto virtual de aprendizagem" (OVA) em apenas 15 (9,3%). Em relação aos atributos dos conceitos, destacaram-se o incentivo à participação, colaboração e interação de discentes (77; 47,8%) e a integração de diversas mídias nos processos de ensino e aprendizagem (74; 46,0%). Quanto aos antecedentes, o mais citado foi a popularização da internet (52; 32,3%). Como consequentes, destacam-se a exigência de uma aprendizagem colaborativa (30; 18,6%) e a necessidade de incorporação de tecnologias à luz de abordagens pedagógicas (28; 17,4%). O conceito AVA teve 12 termos substitutos, com destaque para ambiente virtual de ensino e aprendizagem (12; 7,5%). Já o termo OVA apresentou 5 substitutos, com predomínio de Objeto de Aprendizagem (11; 6,8%). Enquanto conceito relacionado, destacou-se Educação à Distância, discutido em todos os trabalhos analisados. Conclusões: Ambiente virtual de aprendizagem foi compreendido enquanto um sistema computacional que integra funcionalidades e ferramentas que possibilitam a construção de um processo de ensino aprendizagem interativo, online, acessado por navegadores na internet ou em redes locais. Em contrapartida, objeto virtual de aprendizagem foi conceituado enquanto um recurso digital de tamanho limitado que pode ser reutilizado dentro de várias atividades e estratégias pedagógicas. Em síntese, pode-se afirmar que um ambiente virtual de aprendizagem reúne vários e diferentes tipos de objetos virtuais de aprendizagem em um contexto pedagógico comum.

This work was originated through the results of the analysis of the services for the needs of people with disabilities that were permitted by the physical space of two schools of the municipality of Natal/RN. The general objective/goal was to subsidize the elaboration of alternatives for the planning of environments that could be used by any person. The study used the empirical research through the adoption of a multimethod approach including: (i) technical visits oriented by the NBR 9050, (ii) contact with users that have reduced mobility (visually impaired and wheelchair or crutch users) through escorted travels and interviews, and (iii) interview with school managers. The evidence from the research, even though with significant development of laws that guarantee people with disabilities their right to citizenship, the physical environment of our schools still present with many obstacles that prevent the mobility of people with disabilities which proves their lack of readiness to accommodate them. Therefore, the actions taken to address the accessibility has been the adoption of temporary solutions that makes the adaptation more difficult, adds obstacles and reinforces the undesirable segregation, however still very present in our society. Finally, there is the indication that in order to achieve the spatial configuration that promotes social contact and integration in between the persons with different physical status, it is necessary to completely comprehend the activities developed in each space, from the conception of the equipment to the individual learning needs, having in mind creating environments that stimulates the execution of the tasks in an independent manner without the assistance of others. The inclusion regarding attention to accessibility in the decision making process, directed to the arquitectural and urban project, would decrease the constant need to redevelop and adapt spaces, and should be definitely incorporated as an important component in the production of space

This work aimed to study the structure and dynamic of Phytoplankton and Bacterioplankton in a complete cycle of shrimp cultivation (Litopenaeus vannamei) and determine the environmental factors responsible for the structural changes of these communities. The study was realized in a saltwater shrimp farm (Macaíba, RN), between September/2005 and February/2006, and in a freshwater shrimp farm (Ceará Mirim, RN), between May/2007 and September 2007. The samplings were collected weekly in saltwater farm and every fifteen days in freshwater farm. Total phosphorus, chlorophyll a and environmental parameters (pH, dissolved oxygen, salinity, temperature, depth and water transparency) were measured. Qualitative and quantitative analysis of the phytoplankton and bacterioplankton were carried out. The Shannon-Wiener ecologic indexes of diversity and the Pielou equitability indexes were calculated to the phytoplankton. Bacterial density was determined by epifluorescence microscopy. The data were statistically analyzed by Pearson correlation and t-Test. Chlorophycea were predominat in salt water and in the captation/drainage point (24 to 99%). Diatoms had higher wealth. The species Choricystis minor had the highest occurrence (100%) and dominance (90-100%), thus showing its adaptation to the high temperatures, salinity and low water transparency conditions. Filamentous Cyanobacteria like Oscillatoria sp., Pseudoanabaena sp. and Phormidium sp. had constant levels. The negative correlation between chlorophycea and water transparency, and the positive correlation between chlorophyll a and salinity, showed that the phytoplankton was well adapted to the low transparency and to the high salinity. The bacterioplankton was negatively correlated with the total phosphorus and salinity. In freshwater, Cyanobacteria were predominant (>80%), presenting some producers of toxins species like Microcystis sp., Aphanizomenon sp., Cylindrospermopsis raciborskii e Anabaena circinalis. Cyanobacterial density and total phosphorus and chlorophyll a concentrations exceeded the maximum value allowed by legislation. The means of total phosphorus varied from 264 to 627 Wg.L-1 and the means of chlorophyll a oscillated between 22 and 182 Wg.L-1. The phytoplankton species were selected by low availability of the light, high pH, temperature and high availability of total phosphorus. The bacterioplankton showed high densities (5,13 x 107 to 8,50 x107 Bac.mL-1). The studied environments (ponds and rivers) presented a high level of trophic state based on the high concentrations of chlorophyll a and total phosphorus and cyanobacteria dominance. The composition of species in the ponds and rivers was similar, as well as high concentrations of total phosphorus and chlorophyll a, highlighting the pollution caused by the discharges of the farms in natural environment

A produção mundial de nanomateriais tem aumentado nos últimos anos, em função de suas variadas aplicações tecnológicas e, como consequência do seu crescente uso e demanda, poderão existir riscos ambientais sendo a água o ambiente onde muitas destas substâncias podem exercer efeitos deletérios. Um dos nanomaterias de carbono mais utilizados é o fulereno, um composto orgânico lipofílico que pode se comportar como carreador de moléculas tóxicas, potencializando a entrada de contaminantes ambientais em órgãos específicos, fenômeno conhecido como “cavalo de Troia”. As microcistinas (MC) são cianotoxinas produzidas por cianobactérias durante episódios de floração, afetando aos organismos aquáticos e ao ser humano. Diversos estudos demonstram que organismos expostos tanto às MCs quanto ao fulereno podem causar produção excessiva de espécies ativas de oxigênio e alterar os níveis de antioxidantes. Além disso, outro fator que pode vir a intensificar o potencial tóxico de ambos é a incidência de radiação UVA. Sendo assim, procurou-se avaliar os efeitos em parâmetros de estresse oxidativo da co-exposição ex vivo da cianotoxina microcistina-LR (MC-LR) e o nanomaterial de carbono fulereno em brânquias do peixe Cyprinus carpio sob incidência de radiação UVA. Os resultados mostraram que: (a) houve uma perda da capacidade antioxidante no tratamento com MC-LR (baixa concentração) quando coexposta com fulereno no UVA em relação com o tratamento realizado sem co-exposição com fulereno; (b) o fulereno no UV diminuiu a atividade da enzima glutationa-Stransferase (GST) quando comparado com o controle no UV; (c) a MC-LR (alta concentração) co-exposta com fulereno foi capaz de diminuir as concentrações do antioxidante glutationa (GSH) quando comparado com o mesmo tratamento tanto no UVA quanto no escuro sem a co-exposição ao fulereno; (d) o tratamento MC-LR (baixa concentração) com UVA aumentou o dano oxidativo lipídico quando comparado com o controle UVA; (e) o fulereno não causou uma maior bioacumulação da microcistina no tecido. Sendo assim, pode-se concluir que o fulereno não apresentou o potencial de carregador de moléculas nessas concentrações de microcistina, porém, a co-exposição dos compostos diminuem tanto capacidade antioxidante total, como a concentração da GSH, podendo gerar problemas a longo prazo na detoxificação da toxina.

A presença de plantas daninhas em plantios de eucalipto, especialmente nos dois primeiros anos, pode acarretar grandes prejuízos à produtividade, pois reduz a eficiência de aproveitamento dos recursos de crescimento pela cultura. Assim, objetivou-se com este trabalho avaliar os efeitos da interferência de plantas daninhas sobre o crescimento inicial de dois clones de Eucalyptus urophylla x Eucalyptus grandis e a concentração foliar de nutrientes na cultura e nas plantas daninhas. O experimento foi instalado em esquema fatorial 2 x 5 + 7, sendo dois clones de híbridos de Eucalyptus urophylla x Eucalyptus grandis, identificados como CNB001 e CNB016, em competição com cinco plantas daninhas Urochloa decumbens (capim-braquiária), Ipomoea nil (corda-de-viola), Commelina diffusa (trapoeraba), Spermacoce latifolia (erva-quente) e Panicum maximum (capim-colonião). Adicionalmente, foram cultivados os dois clones de eucalipto e as cinco plantas daninhas em monocultivo como padrão de comparação, no delineamento inteiramente casualizado, com quatro repetições. Foram avaliados eucalipto através da altura de plantas, o diâmetro do coleto, o número de ramos, a área foliar, a matéria seca e, o teor foliar de nutrientes do eucalipto, bem como o teor de nutrientes nas folhas das plantas daninhas. O clone CNB001 apresentou crescimento inicial superior ao clone CNB016, no entanto, livre da interferência de plantas daninhas, verificaram-se teores foliares semelhantes para a maioria dos nutrientes em ambos os genótipos. O clone CNB016 mostrou maior sensibilidade à interferência negativa das plantas daninhas que o clone CNB001, sendo seu crescimento inicial mais afetado por Ipomoea nil e a concentração de nutrientes reduzida pelas espécies Panicum maximum, Urochloa decumbens e Commelina diffusa. Panicum maximum apresentou maior interferência com o clone CNB001, enquanto Ipomoea nil pouco influenciou o crescimento e o teor de nutrientes deste híbrido. As plantas daninhas apresentaram elevada capacidade de extrair nutrientes do solo, mesmo em convivência com os clones de Eucalyptus urophylla x Eucalyptus grandis. A interferência imposta à cultura é dependente da espécie infestante e do genótipo de eucalipto.

he present model of agriculture is based on intensive use of industrial inputs, due to its rapid response, but it brings harmful consequences to the environment, and it is necessary the use of modern inputs. And an alternative is the use of rock biofertilizers in agriculture, a product easy to use, with higher residual effect and does not harm the environment. The objective of study was to evaluate the inoculation and co-inoculation of different microorganisms in the solubilization of rock phosphate and potash ground microbial evaluating the best performance in the production of biofertilizers comparing with rocks pure in soil chemical properties and, verify effect of inoculation of the bacterium Paenibacillus polymyxa in the absorption of minerals dissolved in the development of cowpea (Vigna unguiculata [L.] Walp.). The first bioassay was conducted in Laboratory (UFRN) for 72 days in Petri dishes, where the rock powder was increased by 10% and sulfur co-inoculated and inoculated with bacterial suspension of Paenibacillus polymyxa grown in medium tryptone soy broth, Ralstonia solanacearum in medium Kelman, Cromobacterium violaceum in medium Luria-Bertani and Acidithiobacillus thiooxidans in medium Tuovinen and Kelly,and fungi Trichoderma humatum and Penicillium fellutanum in malt extract. Every 12 days, samples were removed in order to build up the release curve of minerals. The second bioassay was conducted in a greenhouse of the Agricultural Research Corporation of Rio Grande do Norte in experimental delineation in randomized block designs, was used 10 kg of an Yellow Argissolo Dystrophic per pot with the addition of treatments super phosphate simple (SS), potassium chloride (KCl), pure rock, biofertilizers in doses 40, 70, 100 and 200% of the recommendation for SS and KCl, and a control, or not inoculated with bacteria P. polymyxa. Were used seeds of cowpea BRS Potiguar and co-inoculated with the bacterial suspension of Bradyrhizobium japonicum and P. polymyxa. The first crop was harvested 45 days after planting, were evaluated in the dry matter (ADM), macronutrients (N, P, K, Ca, Mg) and micronutrients (Zn, Fe, Mn) in ADM. And the second at 75 days assessing levels of macro end micronutrients in plants and soil, and the maximum adsorption capacity of P in soil. The results showed synergism in co-inoculations with P. polymyxa+R. solanacearum and, P. polymyxa+C. violaceum solubilizations providing higher P and K, respectively, and better solubilization time at 36 days. The pH was lower in biofertilizers higher doses, but there was better with their addition to P at the highest dose. Significant reduction of maximum adsorption capacity of phosphorus with increasing dose of biofertilizer. For K and Ca was better with SS+KCl, and Mg to pure rock. There was an effect of fertilization on the absorption, with better results for P, K and ADM with SS+KCL, and N, Ca and Mg for biofertilizers. Generally, the P. polymyxa not influence the absorption of the elements in the plant. In treatments with the uninoculated P. polymyxa chemical fertilizer had an average significantly higher for weight and number of grains. And in the presence of the bacteria, biofertilizers and chemical fertilizers had positive values in relation to rock and control. The data show that the rocks and biofertilizers could meet the need of nutrients the plants revealed as potential for sustainable agriculture
