Lessons Learned During Testing Through Commissioning of the Joint Brazil-US SPORT Mission

SPORT is an international partnership mission between Brazil and the United States to study ionospheric space weather processes that occur at low latitudes. Operating a CubeSat on orbit is certainly one of the most exciting milestones of a CubeSat project, but it is only a part of the mission. To be able to achieve this milestone the efforts of the engineering team were focused late in the project on the integration, testing, and delivery followed by the on-orbit commissioning of the observatory. This paper details the major events and lessons learned by the SPORT team during these phases of the project. SPORT experienced a failure of the battery subsystem during environmental testing followed by physical damage during shipping from Brazil to the United States for Launch. However, more than pointing out these problems, solutions, and lessons learned, this paper explains how the international team worked to overcome the issues and finalize the observatory for delivery and launch. After release from the ISS the SPORT team looked forward to the on-orbit observatory operations, first contacts, and the commissioning phase of the observatory, that is also described on this paper

Morphological study of the male genital organs of Gracilinanus microtarsus

Gracilinanus microtarsus is one of the smallest marsupials on earth. Since it spreads seeds, it has great ecological relevance. However, its reproduction data, especially those related to the anatomy of its reproduction apparatus, are scarce in the literature. Current analysis describes the male genital organs of six adult specimens of G. microtarsus. Macroscopic studies were undertaken on dissected organs, whereas histological studies were performed by inclusion technique in paraffin and by hematoxylin and eosin and Masson trichrome staining. The male genital organs of G. microtarsus consist of a penis with bifid glans, two testicles within a pendular scrotum, placed cranially to the penis, featuring a histology consisting of seminiferous tubules with spermatogonic cells, spermatozoa and Sertoli cells, and a peritubular region with Leydig cells. Testicles are closely associated with epididymis with head, body and tail, with histological differences between the different regions. Deferent ducts, spermatic funicles and annexed glands were reported. The latter were composed of prostate glands divided into three distinct segments and bulbourethral glands. Results show that the male reproduction system of G. Microtarsus is anatomically similar to that of Didelphis sp. and other marsupials groups, with slight details such as the site of each organ.

Importância do cirurgião-dentista no diagnóstico de manifestações orofaciais de violência sexual infantil – revisão de literatura

ABSTRACT Dentists must be able to identify orofacial manifestations resulting from child sexual violence, since most injuries affect their area of ​​expertise, in the head and neck regions. The present work aims, through a literature review, to point out the importance and conduct of this professional in the face of sexual violence against children, related legal aspects, dental findings suggestive of these aggressions, ranging from bite marks with suction ecchymoses on the neck to laceration of the labial and/or lingual frenulum or presence of palatine petechiae, as well as describing the manifestations of Sexually Transmitted Infections in sexually violated minors, the main ones being Syphilis, HPV, Gonorrhea, Herpes, Candidiasis and HIV/AIDS. The information comes from current legislation and national and international specialized literature on the subject, searched in SciELO, PubMed and LILACS databases. Since, in their graduation, the Dentist receives little or no basis regarding the main physical orofacial and psychological manifestations of sexual violence against this public, the vast majority cannot correctly diagnose and, consequently, do not fulfill their role of notifying suspected cases, either out of insecurity, fear or not knowing their legal obligation. It is necessary that the theme is addressed more deeply during undergraduate and graduate studies to train dentistry professionals on how to manage these cases and so that there are no omissions either. KEYWORDS: Child Abuse, Sexual. Mandatory Reporting. Forensic Dentistry.O Cirurgião-Dentista deve ser capaz de identificar manifestações orofaciais provenientes de violência sexual infantil, uma vez que a maioria das lesões acometem sua área de atuação, nas regiões de cabeço e pescoço. O presente trabalho objetiva, por meio de revisão da literatura, apontar a importância e conduta deste profissional frente a violência sexual contra crianças, aspectos legais relacionados, achados odontológicos sugestivos dessas agressões que variam desde marcas de mordidas com equimoses de sucção no pescoço até laceração dos freios labial e/ou lingual ou presença de petéquias palatinas, assim como, descrever a manifestações de Infecções Sexualmente Transmissíveis em menores violentados sexualmente, sendo as principais Sífilis, HPV, Gonorreia, Herpes, Candidíase e HIV/AIDS. As informações são oriundas da legislação vigente e literatura especializada nacional e internacional relativas ao tema, pesquisadas nas bases de dados SciELO, PubMed e LILACS. Visto que, em sua graduação, o Odontólogo recebe pouca ou nenhuma base referente às principais manifestações físicas orofaciais e psicológicas de violência sexual contra este público, a grande maioria não consegue diagnosticar corretamente e, consequentemente, não cumpre seu papel de notificar casos suspeitos, seja por insegurança, medo ou por desconhecer sua obrigação legal. É necessário que a temática seja abordada mais profundamente durante a graduação e pós-graduação para capacitar o profissional da odontologia a como conduzir esses casos e para que também não existam omissões.

Determinantes de estrutura de capital no mercado brasileiro: análise de regressão com painel de dados no período 1999-2003

Este artigo apresenta os resultados de uma investigação sobre os fatores determinantes da estrutura de capital das companhias abertas que atuam no mercado brasileiro. Foi utilizada uma amostra de 91 empresas cobrindo o período de 1999 a 2003. Na realização deste trabalho foi utilizada uma técnica de estimativa mais forte, conjugando Panel Data Dinâmico, que combina dados de corte transversal com séries temporais, com um instrumento de método de momento generalizado. Como proxies de estrutura de capital e alavancagem, foram usados os conceitos contábil e de mercado e seus resultados foram comparados. Em consonância com a literatura da área, foram selecionadas as seguintes variáveis: liquidez corrente, tamanho da empresa, rentabilidade, oportunidade de crescimento, risco de negócio, economia fiscal e crescimento de vendas, tangibilidade, coeficiente de variação e risco de falência. Para os testes, foram utilizados os instrumentos econométricos de GMM e AH. Os resultados econométricos demonstraram-se robustos pelas técnicas utilizadas. Os resultados de análise obtidos foram bastante consistentes com as teorias de Pecking Order e de Trade-off. Esses resultados, também, estão em linha com os observados em estudos similares realizados em diversos países.This article presents the results of an investigation about the determinant factors of the capital structure of publicly held companies that operate in the Brazilian market. The sample group consisted of 91 companies, covering the period from 1999 to 2003. A stronger estimation technique conjugating Dynamic Panel Data, which combines cross-section data with time-series, with a generalized method of moments (GMM) tool was used in the performance of this study. The accounting and market concepts were used as capital structure and leverage proxies, and their results were compared. In conformity with literature from the area, the following variables were selected: current ratio, company size, return, growth opportunity, business risk, fiscal economy and sales growth, tangibility, coefficient of variation and bankruptcy risk. The GMM and AH econometric tools were used for the tests. The econometric results proved robust due to the techniques used. The analysis results obtained were largely consistent with the Pecking Order and Trade-off theories. These results are also in line with the results observed in similar studies carried out in several countries

Estudo comparativo das amplitudes de movimento da coluna cervical em idosos com diferentes níveis de aptidão física

Este estudo tem como objetivo analisar e comparar as amplitudes de movimento (ADM) da coluna cervical em dois grupos de idosos com níveis diferentes de aptidão física. Métodos: Foram selecionados 40 voluntários assintomáticos com idade entre 60-75 anos e subdivididos pelo seu respectivo nível de aptidão física. Os voluntários então foram submetidos a mensuração de suas respectivas ADM pelo inclinômetro Cervical Range of Motion – CROM por um examinador que não tinha conhecimento prévio dos pacientes e seus respectivos grupos. Um teste de confiabilidade intra examinador foi realizado para avaliar a reprodutibilidade do examinador. Resultados: Foi observado que nos movimentos de flexão e extensão não houveram diferenças significativas entre os grupos avaliados. Os movimentos de inclinação lateral direita e esquerda e rotação direita e esquerda apresentaram valores de ADM estatisticamente significantes no grupo de voluntários ativos quando comparados com os sedentários. Conclusão: Conclui-se através deste estudo que o nível de atividade física pode ser um fator benéfico na preservação da ADM em idosos.The aim of this study was to analyze and compare the cervical range of motion (ROM) in elderly people with different fitness levels. Methods: Forty asymptomatic volunteers aged between 60-75 years old were recruited and classified based on their respective fitness level. The volunteers were then submitted to the measurement of cervical ROM with the Cervical Range of Motion (CROM) inclinometer by a blinded examiner. An intrarater reliability test was also performed to evaluate the examiner's reproducibility. Results: There were no significant differences regarding flexion and extension movements in both groups. The lateral right and left flexion and right and left rotation were statistically higher in the fitness group compared to the sedentary individuals. Conclusion: We concluded that the fitness level can be beneficial to preserve cervical ROM in elderly people

Skin color and severe maternal outcomes: evidence from the brazilian network for surveillance of severe maternal morbidity

Taking into account the probable role that race/skin color may have for determining outcomes in maternal health, the objective of this study was to assess whether maternal race/skin color is a predictor of severe maternal morbidity. This is a secondary analysis of the Brazilian Network for Surveillance of Severe Maternal Morbidity, a national multicenter cross-sectional study of 27 Brazilian referral maternity hospitals. A prospective surveillance was performed to identify cases of maternal death (MD), maternal near miss (MNM) events, and potentially life-threatening conditions (PLTC), according to standard WHO definition and criteria. Among 9,555 women with severe maternal morbidity, data on race/skin color was available for 7,139 women, who were further divided into two groups: 4,108 nonwhite women (2,253 black and 1,855 from other races/skin color) and 3,031 white women. Indicators of severe maternal morbidity according to WHO definition are shown by skin color group. Adjusted Prevalence Ratios (PRadj - 95%CI) for Severe Maternal Outcome (SMO=MNM+MD) were estimated according to sociodemographic/obstetric characteristics, pregnancy outcomes, and perinatal results considering race. Results. Among 7,139 women with severe maternal morbidity evaluated, 90.5% were classified as PLTC, 8.5% as MNM, and 1.6% as MD. There was a significantly higher prevalence of MNM and MD among white women. MNMR (maternal near miss ratio) was 9.37 per thousand live births (LB). SMOR (severe maternal outcome ratio) was 11.08 per 1000 LB, and MMR (maternal mortality ratio) was 170.4 per 100,000 LB. Maternal mortality to maternal near miss ratio was 1 to 5.2, irrespective of maternal skin color. Hypertension, the main cause of maternal complications, affected mostly nonwhite women. Hemorrhage, the second more common cause of maternal complication, predominated among white women. Nonwhite skin color was associated with a reduced risk of SMO in multivariate analysis. Nonwhite skin color was associated with a lower risk for severe maternal outcomes. This result could be due to confounding factors linked to a high rate of Brazilian miscegenation.2019CNPQ - Conselho Nacional de Desenvolvimento Científico e Tecnológico402702/2008-

Jet energy measurement with the ATLAS detector in proton-proton collisions at root s=7 TeV

The jet energy scale and its systematic uncertainty are determined for jets measured with the ATLAS detector at the LHC in proton-proton collision data at a centre-of-mass energy of √s = 7TeV corresponding to an integrated luminosity of 38 pb-1. Jets are reconstructed with the anti-kt algorithm with distance parameters R=0. 4 or R=0. 6. Jet energy and angle corrections are determined from Monte Carlo simulations to calibrate jets with transverse momenta pT≥20 GeV and pseudorapidities {pipe}η{pipe}<4. 5. The jet energy systematic uncertainty is estimated using the single isolated hadron response measured in situ and in test-beams, exploiting the transverse momentum balance between central and forward jets in events with dijet topologies and studying systematic variations in Monte Carlo simulations. The jet energy uncertainty is less than 2. 5 % in the central calorimeter region ({pipe}η{pipe}<0. 8) for jets with 60≤pT<800 GeV, and is maximally 14 % for pT<30 GeV in the most forward region 3. 2≤{pipe}η{pipe}<4. 5. The jet energy is validated for jet transverse momenta up to 1 TeV to the level of a few percent using several in situ techniques by comparing a well-known reference such as the recoiling photon pT, the sum of the transverse momenta of tracks associated to the jet, or a system of low-pT jets recoiling against a high-pT jet. More sophisticated jet calibration schemes are presented based on calorimeter cell energy density weighting or hadronic properties of jets, aiming for an improved jet energy resolution and a reduced flavour dependence of the jet response. The systematic uncertainty of the jet energy determined from a combination of in situ techniques is consistent with the one derived from single hadron response measurements over a wide kinematic range. The nominal corrections and uncertainties are derived for isolated jets in an inclusive sample of high-pT jets. Special cases such as event topologies with close-by jets, or selections of samples with an enhanced content of jets originating from light quarks, heavy quarks or gluons are also discussed and the corresponding uncertainties are determined. © 2013 CERN for the benefit of the ATLAS collaboration

Observation of associated near-side and away-side long-range correlations in √sNN=5.02 TeV proton-lead collisions with the ATLAS detector

Two-particle correlations in relative azimuthal angle (Δϕ) and pseudorapidity (Δη) are measured in √sNN=5.02  TeV p+Pb collisions using the ATLAS detector at the LHC. The measurements are performed using approximately 1  μb-1 of data as a function of transverse momentum (pT) and the transverse energy (ΣETPb) summed over 3.1<η<4.9 in the direction of the Pb beam. The correlation function, constructed from charged particles, exhibits a long-range (2<|Δη|<5) “near-side” (Δϕ∼0) correlation that grows rapidly with increasing ΣETPb. A long-range “away-side” (Δϕ∼π) correlation, obtained by subtracting the expected contributions from recoiling dijets and other sources estimated using events with small ΣETPb, is found to match the near-side correlation in magnitude, shape (in Δη and Δϕ) and ΣETPb dependence. The resultant Δϕ correlation is approximately symmetric about π/2, and is consistent with a dominant cos⁡2Δϕ modulation for all ΣETPb ranges and particle pT

Search for squarks and gluinos in events with isolated leptons, jets and missing transverse momentum at s√=8 TeV with the ATLAS detector

The results of a search for supersymmetry in final states containing at least one isolated lepton (electron or muon), jets and large missing transverse momentum with the ATLAS detector at the Large Hadron Collider are reported. The search is based on proton-proton collision data at a centre-of-mass energy s√=8 TeV collected in 2012, corresponding to an integrated luminosity of 20 fb−1. No significant excess above the Standard Model expectation is observed. Limits are set on supersymmetric particle masses for various supersymmetric models. Depending on the model, the search excludes gluino masses up to 1.32 TeV and squark masses up to 840 GeV. Limits are also set on the parameters of a minimal universal extra dimension model, excluding a compactification radius of 1/R c = 950 GeV for a cut-off scale times radius (ΛR c) of approximately 30
