Filtragem de sinais de interferência em espectros dinâmicos solares através de suas componentes de Fourier

Through the data acquisition system of the instrument Brazilian Solar Spectroscope (BSS) at INPE, solar observations in the decimetric radio wave band (1000-2500 MHz) are regularly made. This data is showed as dynamic spectra using the software BSSView created for this purpose. The process of data acquisition can be influenced by various sources, dificulting the resulting dynamic spectrum analysis. The objective of this work is to create a computational routine that eliminates dynamic components of the spectrum attributed to interfering signals and integrate it into BSSView. It was done a preliminary study on the programming language Interactive Data Language (IDL), in which the BSSView was developed, and the Fourier transform, that is required for the application of the filter

A interferência do estado de humor na melhora dos componentes da capacidade funcional em idosos

Mood States are feelings auto regulation deliver to individual better quality of life and healthy aging. The declines of the aging process can be minimized with the regular practice of physical activity and systematized. The objective of this study was to evaluate the effects of a dance program in mood states, depressive symptoms and functional capacity in elderly participants of PROFIT. METHOD: The sample was composed of 20 elderly people. The Training Group was formed by 15 elders who participated in a protocol of dance with duration of 1 hour, three times per week, for 12 weeks and the Control Group, composed of 5 elderly, did not attend any program of physical activity. The participants were evaluated by the List of States of Mind Reduced and Illustrated, Geriatric Depression Scale and the battery of tests of AAHPERD. For the mood states was used non-parametric analysis, according to the technique of Binomial Analysis. To compare the components of functional capacity between the groups was used analysis of variance for repeated measures two-way ANOVA and the level of significance was set at 5 %. RESULTS: The functional components remained favorable, highlighting Agility (pre = 21.03 ± 1.64 sec./ post = 18.63 ± 2.26 sec.) And aerobic endurance (pre = 495.94 ± 46.48 sec. / post = 448.01 ± 12.27 sec.). In the comparison between positive and negative functional levels and mood states showed no relationship between these variables, dealing with different aspects and has influence one another. The state post-dancing sessions mood in GT were more positive even for elderly patients with depressive symptoms even unproven statistically, depressive symptoms were maintained or reduced mostly. CONCLUSION: The dance practice maintains the functionality of components; modifies mood states to positive levels and reduces or prevents the onset of depressive symptoms and complications in elderly

Comunidades componentes de helmintos de anfíbios: análise comparativa entre duas localidades sob ação antrópica no município de São Luiz do Paraitinga, SP

With the degradation of Atlantic Forest over the years, the area that this ecosystem has occupied before decreased and in a lot of cases it was separated in little fragments, each one isolated in a different way depending of the local antropic action. In this context, this study compares the helminth fauna of anurans from two different fragments of Atlantic Forest, one inset in a matrix of eucalyptus (Eucaliptus sp.) reforestation and the other in a matrix of pasture (Brachiaria sp.), verifying if there is any difference between the structure of helminth communities. There were collected 155 anurans in both fragments, being 77 Hypsiboas albopunctatus, 18 Hypsiboas faber, 27 Hypsiboas polytaenius e 33 Dendropsophus minutus. These were weighted and their snout-vent lengths were measured. After the animals were euthanatized and their internal organs and coelomatic cavity were evaluated for helminth infection. There were identified one trematode species (Haematoloechus fuelleborni) and 14 nematode species (Aplectana sp., Cosmocerca parva, Cosmocerca sp1., Cosmocerca sp2., Cosmocercoides sp., Falcaustra mascula, Cosmocercidae larvae, nematode larvae, Physaloptera sp. larvae, Ochoterenella sp., Oswaldocruzia subauricularis, Raillietnema simples, Rhabdias sp. e Schrankiana sp.). The hylids' helminth fauna studied in São Luiz do Paraitinga fragments were relatively rich, being registered 15 helminth species in the captured anurans. The comparison between the fragments did not show differences in relation of the composition and abundance of helminth fauna in spite of the individualities of each environment

Concentração de tensões em peças e componentes estruturais - uma abordagem através do método dos elementos finitos

Any failure process that may occur in a part probably is located where the stress exceeded the level of resistance. When a part or component has a sharp change in geometry, such as slots, holes, grooves, bumps or other irregularities, there is an increased concentration of stress at a specific location of the part. The objective of this study is to determine the maximum stresses in structural parts and components using the equations of elasticity theory in conjunction with the stress concentration factor experiment and compare them with results obtained by finite element method

Avaliação das características físico-químicas e microbiológicas dos componentes fibrosos obtidos da moagem úmida de grãos de milho

Fibers are non-digestible materials by human organism, and they are insoluble in specific conditions. The corn fiber has been used as an alternative to enrich the food products for human consumption, in order to add nutritious value to this co-product. This study aimed at determining the chemical and fractions components of corn fiber, extracted by semi-wet milling in laboratory (LabF), and by semi-humid milling in industrial process (IndF); and microbiological analyses were perform in the last fraction. The fiber composition differed significantly among these two products as to moisture, ash, lipids, proteins, insoluble dietary fiber, neutral detergent fiber (NDF), acid detergent fiber (ADF), cellulose and lignin contents. The sample IndF showed microbiological parameters in compliance with the specifications for consumption. The investigated corn fiber may effectively contribute to increase the fiber intake in the diet. As the industrially processed fiber (IndF) showed compliant microbiological parameters with the specifications for food, this component might be incorporated into the food products formulation.

Componentes e dinâmicas organizacionais de uma parceria para a aprendizagem de português e alemão via teletandem

The article aims to share results of a study case of ethnographic basis which focus two foreign language learners, one is Portuguese and the other is German, and their commitment in helping each other mutually learning such languages (LUVIZARI-MURAD, 2011). We specifically propose to introduce a systemic outlook of the foreign language process via Teletandem, in terms of the elements which compound it and of how such components interact and configurea space of transformation and development for its participants.

Quando o lírico e o narrativo se encontram em Nuno Júdice

Nuno Judice’poetry has a peculiar discourse, whose devices of construction mixe poetry and prose in order to eliminate the borders between the two kinds of language. The Classical tradition is a constant reference in his poetry, by means of the imagery and the allegory in which some Greek myths are mentioned. Nevertheless, the context of modernity from which the poet Nuno Judice emerges put together the dimensions of space and time so as it is impossible to separate them. In this paper we analyse two poems extracted from the book As Regras da Perspectiva (1990) and our purpose is to discuss some literary questions as the metalanguage, the sensations, the lyric subjectivity, the narrative trends, the special meanings and the forms of the world.

Avaliação dos componentes de óleos essenciais 1,8-cineol, β-cariofileno e α-humuleno como possíveis repelentes para Aedes (Stegomyia) aegypti (Diptera: Culicidae)

Aedes aegypti, mosquito da família Culicidae responsável pela transmissão dos vírus da dengue, da febre amarela urbana e da febre chikungunya, apresenta grande proliferação em áreas urbanas das regiões tropicais e subtropicais, além de representar um fator de incômodo por causar alergias devido à inoculação dos componentes salivares durante o processo do repasto sanguíneo. Como forma de evitar os problemas causados por eles, o repelente mais usado e registrado comercialmente desde 1957 é o DEET (N,N-dietil-3-metilbenzamida ou N,N-dietil-meta-toluamida), que apesar de apresentar eficácia comprovada possui determinada toxicidade quando utilizado por crianças e por mulheres grávidas ou lactantes. Atualmente, grande parte dos estudos sobre novas substâncias repelentes envolvem óleos essenciais de plantas, principalmente por serem atóxicos, biodegradáveis, possuírem um preço mais acessível e uma ampla atividade contra diferentes espécies de mosquitos. Os terpenos 1,8-cineol, β-cariofileno e α-humuleno podem ser encontrados em óleos essenciais de uma grande variedade de plantas e apesar de dados da literatura mostrarem uma eficácia dessas substâncias como repelentes para outras espécies de insetos, até o presente momento não existem estudos que relacionam porcentagem de repelência ao longo do tempo para avaliar o potencial de repelência das mesmas para culicídeos.O presente estudo avaliou tais substâncias como possíveis repelentes para A. aegypti, utilizando o DEET como controle positivo. Para avaliar a eficácia do β-cariofileno foi utilizada a BG-cage, uma gaiola desenvolvida especificamente para testes de repelência onde o voluntário expõe um braço sob uma abertura coberta por uma tela onde os mosquitos pousam, mas não picam. Os testes foram repetidos a cada 30 minutos após a aplicação do produto por um tempo máximo de duas horas (seguindo a recomendação de reaplicação do produto comercial ...

Projeto mecânico de um modelo para túnel de vento e validação de seus componentes à partir de simulações em software de elementos finitos

The objective of this study was to develop a model that allows testing in the wind tunnel at high angles of attack and validates its most critical components by analyzing the results of simulations in finite element software. During the project this structure suffered major loads identified during the flight conditions and, from these, we calculated the stresses in critical regions defined as the parts of the model that have higher failure probabilities. All aspects associated with Load methods, mesh refining and stress analysis were taken into account in this approach. The selection of the analysis software was based on project needs, seeking greater ease of modeling and simulation. We opted for the software ANSYS® since the entire project is being developed in CAD platforms enabling a friendly integration between software's modeling and analysis

Descarte dos componentes de filmes radiográficos e aventais de chumbo utilizados nas clínicas odontológica ou radiológica

Várias resoluções e leis visam minimizar e/ou adequar os resíduos gerados, dentre outros aspectos. Nesse sentido, a Disciplina de Radiologia, funcionários que trabalham no setor e docentes ligados a biossegurança e sustentabilidade ambiental estudaram as referidas normas e leis, além de artigos científicos relacionados ao descarte dos resíduos gerados em radiologia para realizar o descarte correto desses materiais e para orientar e conscientizar os acadêmicos sobre o assunto. Verificou-se que os resíduos gerados com a radiografia convencional são considerados resíduos químicos (tipo B) e devem ser descartado separadamente dos resíduos tipo A (infectantes), C (radioativos), D (comum) e dos E (perfuro-cortantes), visto que podem ser reutilizados, recuperados ou reciclados, e em última instância, podem ser dispostos em aterro de resíduos perigosos Classe I.
