Epidemiological study of patients treated at the outpatient clinic of the Burn Treatment Center of the Hospital Municipal do Tatuapé between January 2019 and January 2020

Introduction: Burns are in fourth place as the most common type of trauma globally, generating a challenge due to the severity of patients' injuries. This study investigates the epidemiological profile of patients treated at the Burn Treatment Center (BTC) outpatient clinic of the Hospital Municipal do Tatuapé (HMT/SP). Methods: Data obtained from the outpatient records of the BTC outpatient clinic of the HMT/SP were analyzed from January 2019 to January 2020, using the following variables: gender, age, causal agent, burn extension, and affected region. Results: Higher predominance of burns in males (55.3%). There was a higher percentage in the population between 21 and 30 years (15.9%), followed closely by children under 10 years of age (15.8%). The leading causative agent was scalded/heated liquids (56.8%); followed by contact burn (14.7%), the vast majority of patients were affected by medium-sized burn (90.1%), i.e., between 11 and 20% of the burned body surface and the thorax/abdomen the most affected region. Conclusion: The epidemiological profile demonstrated in this study was compatible, in most data, with the profile found in other centers specialized in treating burns

Optimasi Portofolio Resiko Menggunakan Model Markowitz MVO Dikaitkan dengan Keterbatasan Manusia dalam Memprediksi Masa Depan dalam Perspektif Al-Qur`an

Risk portfolio on modern finance has become increasingly technical, requiring the use of sophisticated mathematical tools in both research and practice. Since companies cannot insure themselves completely against risk, as human incompetence in predicting the future precisely that written in Al-Quran surah Luqman verse 34, they have to manage it to yield an optimal portfolio. The objective here is to minimize the variance among all portfolios, or alternatively, to maximize expected return among all portfolios that has at least a certain expected return. Furthermore, this study focuses on optimizing risk portfolio so called Markowitz MVO (Mean-Variance Optimization). Some theoretical frameworks for analysis are arithmetic mean, geometric mean, variance, covariance, linear programming, and quadratic programming. Moreover, finding a minimum variance portfolio produces a convex quadratic programming, that is minimizing the objective function ðð¥with constraintsð ð 𥠥 ðandð´ð¥ = ð. The outcome of this research is the solution of optimal risk portofolio in some investments that could be finished smoothly using MATLAB R2007b software together with its graphic analysis

Search for heavy resonances decaying to two Higgs bosons in final states containing four b quarks

A search is presented for narrow heavy resonances X decaying into pairs of Higgs bosons (H) in proton-proton collisions collected by the CMS experiment at the LHC at root s = 8 TeV. The data correspond to an integrated luminosity of 19.7 fb(-1). The search considers HH resonances with masses between 1 and 3 TeV, having final states of two b quark pairs. Each Higgs boson is produced with large momentum, and the hadronization products of the pair of b quarks can usually be reconstructed as single large jets. The background from multijet and t (t) over bar events is significantly reduced by applying requirements related to the flavor of the jet, its mass, and its substructure. The signal would be identified as a peak on top of the dijet invariant mass spectrum of the remaining background events. No evidence is observed for such a signal. Upper limits obtained at 95 confidence level for the product of the production cross section and branching fraction sigma(gg -> X) B(X -> HH -> b (b) over barb (b) over bar) range from 10 to 1.5 fb for the mass of X from 1.15 to 2.0 TeV, significantly extending previous searches. For a warped extra dimension theory with amass scale Lambda(R) = 1 TeV, the data exclude radion scalar masses between 1.15 and 1.55 TeV

Um breve balanço da pesquisa sobre violência escolar no Brasil A brief survey of the research on school violence in Brazil

O artigo realiza balanço da pesquisa sobre as relações entre violência e escola no Brasil, após 1980. Examina os raros diagnósticos quantitativos em torno do tema e a produção discente (dissertações e teses) na pós-graduação em Educação, no mesmo período. Apesar de ainda ser incipiente, a produção já traça um quadro importante do fenômeno no Brasil, mostrando as principais modalidades: ações contra o patrimônio - depredações, pichações - e formas de agressão interpessoal, sobretudo entre os próprios alunos. Durante esse período a violência em meio escolar tanto foi examinada como decorrência de um conjunto significativo de práticas escolares inadequadas, quanto foi investigada como um dos aspectos que caracterizam a violência na sociedade contemporânea. Nesse último enfoque, parte dos trabalhos pesquisou a dinâmica de funcionamento de escolas situadas em áreas sob a influência do tráfico de drogas ou do crime organizado e um pequeno conjunto buscou entender o comportamento dos alunos como uma forma de sociabilidade marcada pelas agressões e pequenos delitos, caracterizada como incivilidade, que se origina na crise do processo civilizatório da sociedade contemporânea.<br>The article surveys the research on the relationships between violence and school in Brazil after 1980. It examines the rare quantitative diagnostics about the issue, and the theses and dissertations produced in graduate programs in Education in the same period. Although still incipient those studies already draw an important picture of the phenomenon in Brazil, displaying the leading modes of violence: acts against property - vandalism, graffiti - and interpersonal aggression, mainly among the pupils. During this period, violence at school has been examined both as a consequence of a significant set of inadequate school practices, and as one of the aspects that characterizes the violence of contemporary society. Under the latter viewpoint, some of the works have investigated the dynamics of the workings of schools located in areas influenced by drug traffic or organized crime, and a small subset tried to understand the behavior of pupils as a socialization marked by aggressions and petty crime, characterized as incivility originated in the crisis of civilizatory process of contemporary society

Measurement of the ZZZZ production cross section and Z→ℓ+ℓ−ℓ′+ℓ′−Z \to \ell^+ \ell^- \ell^{\prime +} \ell^{\prime -} branching fraction in pppp collisions at s=13\sqrt{s} = 13 TeV

Four-lepton production in proton-proton collisions, $pp \to (Z/\gamma*)(Z/\gamma*) \to Z \to \ell^+ \ell^- \ell^{\prime +} \ell^{\prime -}$, where $\ell,\ell^\prime$ = e or $\mu$, is studied at a center-of-mass energy of 13 TeV with the CMS detector at the LHC. The data sample corresponds to an integrated luminosity of 2.6 inverse femtobarns. The ZZ production cross section, $\sigma(pp \to ZZ) = 14.6^{+1.9}_{-1.8}$ (stat)$^{+0.5}_{-0.3}$(syst)$\pm$ 0.2 (theo) $\pm$ 0.4 (lumi) pb, is measured for events with two opposite-sign, same-flavor lepton pairs produced in the mass region 60 $$ 4 GeV for all opposite-sign lepton pairs. The results are in agreement with standard model predictions
