    INTRODUÇÃO: Desenvolver em supervisão um projeto de intervenção que proporcione ao idoso uma melhor qualidade de vida. A Instituição escolhida foi o Centro de Referência de Assistência Social (CRAS) no município de Tiros. Foi elaborado um trabalho em grupo, da estagiaria com os idosos, contendo atividades para desenvolver a visão, a audição e coordenação motora entre outras habilidades e funções. Houve dificuldades entre os idosos, foi observado que a adaptação às mudanças acarreta sofrimento, marcada por um sentimento de solidão e isolamento. OBJETIVO: Propor psicoterapia em grupo com idosos para promover qualidade de vida significativa a eles.  MÉTODO: Diversas atividades foram contempladas, a bioenergética, relaxamento, dinâmicas de grupo, entre outras, visando melhorar a autoestima, a depressão, a socialização; além de informações e reflexões. Com isto, os participantes, ao falarem de si, puderam melhorar suas relações interpessoais e intrapessoais. Ao término das dinâmicas sempre é oferecido um lanche ao grupo de idosos. RESULTADOS: O presente estágio proporcionou a oportunidade de refletir sobre as intempéries pelas quais o idoso vivencia dentro de uma Instituição, nota-se, que o isolamento não é um problema específico da velhice, muitas vezes isso acontece por falta de estímulo, é possível perceber que o mundo está cada dia mais acelerado, logo o idoso muitas vezes não consegue acompanharas demandas da vida. Ele tem de enfrentar filas, desrespeito e até agressão por parte de quem deveria estar cuidando. Durante a sua vida, esse indivíduo pode ter sido desestimulado a aprender e agora com o raciocínio mais lento, as dificuldades aparecem e com ela o desânimo de fazer atividades diárias, como cuidar de sua própria higiene, da alimentação e até mesmo se divertir. É possível observar que além da idade cronológica, existem outros conceitos de idade, como a existencial, onde o idoso não está preso somente às condições físicas, mas também, a uma somatória de experiências vivenciadas durante sua vida, como seus desejos e frustrações. CONSIDERAÇÕES FINAIS: A partir da adesão nas atividades propostas e de suas devolutivas, conclui-se que o objetivo foi alcançado. Mesmo com as dificuldades e obstáculos enfrentados, durante o estágio, a experiência foi gratificante

    A permanent magnet hall thruster for pulsed orbit control of lunar polar satellites

    Get PDF
    Future Moon missions devoted to Lunar surface remote sensing, for example, will require very _ne and accurate orbit control. It is well known that Lunar satellites in polar orbits will su_er a high increase on the eccentricity due to the gravitational perturbation of the Earth. Without proper orbit correction the satellite lifetime will decrease and end up in a collision with the Moon surface. It is pointed out by many authors that this e_ect is a natural consequence of the Lidov-Kozai resonance. We studied di_erent arcs of active lunar satellite propulsion, centered on the orbit apoapsis or periapsis, in order to be able to introduce a correction of the eccentricity at each cycle. The proposed method is based on an approach intended to keep the orbital eccentricity of the satellite at low values

    Beyond the shortest path: the path length index as a distribution

    Full text link
    The traditional complex network approach considers only the shortest paths from one node to another, not taking into account several other possible paths. This limitation is significant, for example, in urban mobility studies. In this short report, as the first steps, we present an exhaustive approach to address that problem and show we can go beyond the shortest path, but we do not need to go so far: we present an interactive procedure and an early stop possibility. After presenting some fundamental concepts in graph theory, we presented an analytical solution for the problem of counting the number of possible paths between two nodes in complete graphs, and a depth-limited approach to get all possible paths between each pair of nodes in a general graph (an NP-hard problem). We do not collapse the distribution of path lengths between a pair of nodes into a scalar number, we look at the distribution itself - taking all paths up to a pre-defined path length (considering a truncated distribution), and show the impact of that approach on the most straightforward distance-based graph index: the walk/path length

    The test proposed by Scott Knott (1974), a procedure of means grouping, is an effective alternative to performprocedures of multiple comparisons without ambiguity. This study aimed to propose a modification related to the partitioningand means grouping in the said procedure, to obtain results without ambiguity among treatments, organized in morehomogeneous groups. In the proposed methodology, treatments that did not participate in the initial group are joined for a newanalysis, which allows for a better group distribution. In a comparative study, four experiments were simulated in a randomizedcomplete block design. The first consisted of 10 and the other 3 of 100 treatments. All experiments were performed in threereplications at a significance level of 0.05 for the means grouping test. Only in the third experiment of those of 100 treatmentsthe groups formed by Scott-Knott did not differ from the methodology proposed here. The proposed methodology is consideredeffective, aiming at the identification of elite cultivar groups for recommendation

    Plastics Polymers Degradation by Fungi

    The studies on plastic degradation are very important for the development of biodegradable plastics, and for reduction of pollution, since plastic waste can remain in the environment for decades or centuries. We have showed the degradation of oxo-biodegradable plastic bags and green polyethylene by Pleurotus ostreatus. This fungus can also produce mushrooms using these plastics. The plastic degradation was possibly by three reasons: (a) presence of pro-oxidant ions or plant polymer, (b) low specificity of the lignocellulolytic enzymes, and (c) the presence of endomycotic nitrogen-fixing microorganisms. In this chapter, the plastic bags’ degradation by abiotic and microbial process using the exposure to sunlight and the use of a white-rot fungus will described. The physical, chemical, and biological alterations of plastic were analyzed after each process of degradation. The degradation of plastic bags was more effective when the abiotic and biotic degradations were combined

    An additional brain endocast of the ictidosaur riograndia guaibensis (Eucynodontia: Probainognathia): Intraspecific variation of endocranial traits

    Get PDF
    Recently, the morphology and encephalization of the brain endocast of the Triassic non-mammaliaform probainognathian cynodont Riograndia guaibensis were studied. Here, we analyzed the brain endocast of an additional specimen of this species. The new endocast shows well-defined olfactory bulbs and a median sulcus dividing the hemispheres, traits that were not clearly observed in the first studied specimen. Encephalization quotients were also calculated, revealing similar values to other non-mammaliaform cynodonts and lower than those of the first analyzed specimen. The analyzed cranium is slightly larger than the first studied one and may represent an advanced ontogenetic stage. Hence, these differences may be related to the intraspecific variation of this cynodont or alternatively, to the preservation of each specimen.Fil: Kerber, Leonardo.

    O objetivo deste trabalho foi avaliar a influência da intensidade de amostragem, do tamanho da coleção de germoplasma inicial e da variância da amostragem sobre a qualidade das respectivas coleções nucleares, quanto à representatividade das coleções iniciais. Foram simulados sete tamanhos de coleções iniciais e utilizadas seis intensidades de amostragem para estabelecimento de coleções nucleares, utilizando caracteres morfoagronômicos. Determinaram-se o número de grupos formados, o coeficiente de coincidência entre a coleção nuclear e a coleção inicial e o coeficiente de determinação dos acessos amostrados para comporem a coleção nuclear. Também foi proposto o uso de uma estratégia alternativa para estabelecer coleções nucleares, de forma a maximizar a diversidade entre os acessos. O tamanho da coleção inicial influencia a intensidade de amostragem empregada na obtenção da coleção nuclear. A amostragem de acessos pelo método de Tocher, com critério de aglomeração inverso, mostrou-se eficiente na obtenção de coleções nucleares. As diferentes magnitudes de variância das coleções iniciais não influenciaram os coeficientes de determinação (R2) nem os coeficientes de coincidência entre a coleção inicial e as respectivas coleções nucleares.The objective of this work was to evaluate the effect of sampling intensity, initial collection's size and its variance over the quality of the respective core collections, in terms of representation of the initial collections. Therefore, simulations were performed for seven sizes of the initial collections and six sampling intensities for the establishment of core collections were used, comprising morpho-agronomic traits. Groups formed were determined, as well as the coincidence coefficient between the core and the initial collection, and the determination coefficient of the accessions sampling to compose the core collection. The use of an alternative strategy was proposed to establish core collections, this strategy maximizes the diversity among the accessions. The size of initial collections affects the sampling intensity to be used to obtain a core collection. The selection of accessions with the method of Tocher, comprising criteria of inverse grouping, was efficient for the formation of the core collections. The different magnitudes of variance of the initial collections did not affect either the coefficient of determination (R2) or the coincidence rate between initial collections and respective core collection

    Repeatability and application of tethered swimming tests for recreational swimmers

    Get PDF
    Tethered swimming tests are applied to evaluate propulsive forces in crawl stroke and may also be used to evaluate force applied by the movement of lower (leg kicking) and upper limbs (arm stroke). Considering the large number of recreational swimmers, this tool may be useful for coaches to evaluate the technique and force production by swimmers. As little attention has been paid to the application of these tests with recreational swimmers, the aims of this study were to verify the repeatability of the tethered swimming test for arm stroke, leg kicking and crawl stroke and to verify the relationship between performance in a 50-m test and in the tethered test with recreational swimmers. In this case, repeatability was defined as the agreement between the results of two successive evaluations. Ten male swimmers performed two 30-s maximal intensity tethered swimming tests with leg kicking, arm stroke and crawl stroke and three 50-m crawl stroke tests. Repeatability was found for mean force of all tests and for impulse evaluated in crawl stroke. Inverse relationship of the time to complete 50 m with the maximum and mean forces and with the impulse in the crawl stroke and an inverse relationship between time to complete 50 m and the mean force in the leg kicking were observed. Therefore, results from full tethered swimming tests applied with recreational swimmers may help swimming coaches
