    OBJECTIVE: This paper has the purpose of evaluate the elbow carrying angle by clinic and radiographic examination in normal children and determine the range of normality according to age from childhood to skeletal maturity and also check if there is a statistically significant difference between the clinical and radiographic measurements. METHODS: We evaluated 510 persons with ages varying from 1 to 18 years distributed in groups with 30 subjects according to the age group with 1-year interval. We performed radiographic examination of the elbow and measured the angle formed by the long axis of the humerus and ulna. The data were statistically analyzed using the student t-test. RESULTS: We determined a normal curve of the study population where there was an increase of this parameter with the progression of age. No statistically significant difference between the clinical and radiographic measures. CONCLUSION: The average of the elbow carrying angle was 12,78 ± 5,35 degrees for females and 11,20 ± 4,45 degrees for males. This values increase progressively from childhood until 16 years when we notice stabilization. There was no statistical difference between the clinical and radiographic measurements.OBJETIVO: Avaliar clínica e radiograficamente o ângulo de carregamento do cotovelo (ACC) determinando uma curva de normalidade de acordo com faixas etárias (da infância à maturidade esquelética) e comparar as medidas clínicas e radiográficas. MÉTODOS: Avaliamos 510 indivíduos (1020 cotovelos), com idades entre 1 e 18 anos, distribuídos em grupos de 30 conforme faixas etárias, com intervalo de 1 ano. Excluímos os portadores de: fraturas do cotovelo, sequelas, malformações, doenças genéticas, afecções inflamatórias e frouxidão ligamentar. Mensuramos clinicamente o ACC bilateralmente com goniômetro, onde obtivemos duas medidas por dois examinadores onde média destas foi considerada. Realizamos radiografias ântero-posteriores dos cotovelos e aferimos os ângulos formados pelos eixos do úmero e da ulna. Todos os dados foram analisados estatisticamente pelo teste t student. RESULTADOS: Determinamos uma curva de normalidade onde observamos aumento deste parâmetro conforme a progressão da idade. Não observamos diferença significante entre as medidas clínicas e radiográficas. CONCLUSÃO: A média do ângulo de carregamento para o sexo feminino foi 12,78º ± 5,35 e para o masculino 11,20º ± 4,45. Este valor aumenta progressivamente da infância até os 16 anos quando observamos estabilização. Não houve diferença estatística significante das medidas clínicas e radiográficas.Universidade Federal de São Paulo (UNIFESP)UNIFESPSciEL

    The objective of this work was to compare the performance of the nonlinear Gompertz, logistic, and von Bertalanffy equations, to describe the growth curve of immunocastrated male pigs from birth until reaching 140 kg body weight. Standard error, number of iterations, mean square of the error, and coefficient of determination were compared between the models. The logistic and von Bertalanffy equations do not accurately estimate the initial and slaughter weights. The Gompertz equation shows the highest reliability and is, therefore, the most suitable one to describe the growth curve of immunocastrated pigs from birth until 140 kg body weight is reached.O objetivo deste trabalho foi comparar o desempenho das equações não lineares de Gompertz, logística e a de von Bertalanffy, para descrever a curva de crescimento de suínos machos imunocastrados, desde o nascimento até atingirem 140 kg de massa corporal. O erro-padrão, o número de iterações, o quadrado médio do erro e o coeficiente de determinação foram comparados entre os modelos. A equação logística e a de von Bertalanffy não estimam com precisão as massas inicial e de abate. A equação de Gompertz apresenta maior confiabilidade e é, portanto, a mais adequada para descrever a curva de crescimento de suínos imunocastrados, desde o nascimento até a obtenção de140 kg de massa corporal

    The present work aims at the preliminary evaluation of the Paspalun repens macrophyte dry biomass adsorbent material of zinc (Zn) and copper (Cu) metals from water. The diversity of Species is due to the extensive aquatic environment where it is inserted. The Paspalun repens species comes from the Buiuçu lake located in the region of Parintins-Amazonas- Brazil. The macrophyte was dried in a mill and then a digestion through biomass microwaves was done before and after its exposure to the solutions containing different concentrations of zinc and copper (1.00, 1.50, 2.00, 3.00 mg mL-1 of metals) for a period of 48 hours. As a source of the metals, zinc sulfate (ZnSO4 7H2O) for zinc, and copper sulfate (CuSO4 5H2O) for copper were used as the source. As a result, the efficiency of Paspalun repens was observed in the metals removal, the highest removal percentage, of 29.67 and 37.07% in the leaves, whereas in the root it was 25.25 and 32.84% (at the concentration 1.0 and 2.0 mg/mL consequently), was of zinc, therefore the dry biomass of this species can be considered as a low cost alternative material in the removal of these heavy metals, contributing to the improvement of water quality. © 2017 Universidade Federal de Sao Carlos.

    Beekeeping in Brazil: A Bibliographic Review

    Get PDF
    Brazil presents favorable conditions for beekeeping, having a suitable climate; native flowering plants with great potential for the production of honey, pollen, propolis, and royal jelly; and bees adapted to our conditions, tolerant to the main apicultural diseases and highly productive. Through the meliponiculture, the conservation of mainly native forest areas is allowed; therefore, they are the best environments for the creation of native bees and production of by-products of the beehive with quality. The stingless bees are very sensitive to any disturbance due to anthropogenic action. A systematic bibliographical review was carried out in different electronic databases, through descriptors referring to beekeeping in Brazil. The identification of articles and their inclusion occurred between January 2018 and April 2018. The bibliographic research was conducted in the following electronic databases: (1) Scientific Electronic Library Online (SciELO), (2) Public Library of Science (PLOS) Biology, and (3) ScienceDirect. In order to help in the process of standardization of bee products and traceability of the production chain, it was possible to draw a profile of the main bioactive substances of the beehive products of Brazil. It was also possible to relate the benefits of an adequate management of beekeeping and meliponiculture in Brazil

    Get PDF
    On 1 April 2022, the AlfaCrux CubeSat was launched by the Falcon 9 Transporter-4 mission, the fourth SpaceX dedicated smallsat rideshare program mission, from Space Launch Complex 40 at Cape Canaveral Space Force Station in Florida into a Sun-synchronous orbit at 500 km. AlfaCrux is an amateur radio and educational mission to provide learning and scientific benefits in the context of small satellite missions. It is an opportunity for theoretical and practical learning about the technical management, systems design, communication, orbital mechanics, development, integration, and operation of small satellites. The AlfaCrux payload, a software-defined radio hardware, is responsible for two main services, which are a digital packet repeater and a store-and-forward system. In the ground segment, a cloud-computing-based command and control station has been developed, together with an open access online platform to access and visualize the main information of the AlfaCrux telemetry and user data and experiments. It also becomes an in-orbit database reference to be used for different studies concerned with, for instance, radio propagation, attitude reconstruction, data-driven calibration algorithms for satellite sensors, among others. In this context, this paper describes the AlfaCrux mission, its main subsystems, and the achievements obtained in the early orbit phase. Scientific and engineering assessments conducted with the spacecraft operations to tackle unexpected behaviors in the ground station and also to better understand the space environment are also presented and discussed.Fundação de Apoio à Pesquisa del Distrito Federal (FAPDF), Brasil | Ref.

    It is a pilot study, involving 15 children that were commited at the Hospital da Criança: Obras Sociais de Irmã Dulce, Salvador, Bahia. The objective of this study is the investigation of family’s perception about the pediatric patient with chronic illness. The responsible for the patient answered a questionnaire that approached subjects regarding the partner demographic profile, family  knowledge degree about the disease, behavior alterations in child and its family, besides the impression of prognostic and  the medical services that were offered to the researched population. The results evidenced that some kind of behavior alteration were presented by all evaluated population, being more frequent symptoms of: sadness; anxiety; isolation and sleepness. The parents referred that after the appearance of the disease, the more common manifestations were: increase of the familiar union, feeling of fear, anxiety and concern with physical sequels. Regarding the model of hospital care, it was revealed that they were satisfied with the quality and efficiency of the medical service. However, they consider insufficient the psychological support to the child and the family throughout the confrontation of the chronic disease. The next phase of this study should make possible a more consistent and inclusive analysis concerning the proposed theme.Trata-se de um estudo piloto que envolve 15 crianças internadas no Hospital da Criança: Obras Sociais de Irmã Dulce, Salvador, Bahia, realizado com o objetivo de investigar a percepção da família perante o paciente pediátrico, portador de enfermidade crônica. Para tanto, o responsável pelo paciente respondeu a um questionário que abordou questões referentes a perfil sociodemográfico, grau de conhecimento da família em relação à doença, percepção quanto a alterações comportamentais ocorridas na criança e na família, além da impressão quanto ao prognóstico e serviços médicos prestados à população pesquisada. Os resultados desta pesquisa evidenciaram que toda a população avaliada apresentou algum tipo de alteração comportamental, sendo mais freqüentes os sintomas: tristeza, ansiedade, isolamento e sonolência. Os pais referiram como manifestações mais comuns, após o surgimento da doença: maior união familiar, sentimento de medo, ansiedade e preocupação com seqüelas físicas. No que diz respeito ao padrão de assistência hospitalar, revelaram-se satisfeitos com a qualidade e eficiência do serviço médico prestado. Entretanto, consideram insuficiente o suporte psicológico à criança e à família no enfrentamento da doença crônica. A próxima fase deste estudo deverá possibilitar uma análise mais consistente e abrangente acerca do tema proposto
