    O objetivo deste trabalho foi avaliar a diversidade fenotípica da Campomanesia adamantium, com base nas características morfológicas dos frutos e emergência das sementes. Foram avaliadas dez populações em área de Cerrado Sentido Restrito, em Dourados-MS. A marcação das coordenadas de cada população foi obtida em função das diferenças fenotípicas apresentadas entre elas, distribuídas numa área de 32 ha. A coleta dos frutos foi realizada na segunda quinzena de dezembro de 2009, época de frutificação da espécie. Para o estudo da biometria, utilizou-se o delineamento experimental inteiramente casualizado, com dez tratamentos, correspondentes ás populações e dez repetições de dez frutos, correspondentes ás unidades experimentais. O estudo do comportamento germinativo das sementes foi desenvolvido em condições de casa de vegetação utilizando o delineamento blocos casualizados, com quatro repetições de dezesseis sementes, como unidade experimental, para cada população. No estudo biométrico dos frutos e no comportamento germinativo das sementes, observou-se a existência de grupos estatisticamente diferentes para cada característica avaliada. As populações de C. adamantium, em área nativa, apresentaram frutos com alta variabilidade fenotípica. Na casa de vegetação, as plântulas obtidas por propagação de sementes apresentaram uma menor proporção de diversidade fenotípica. Considerando-se as características dos frutos e propagativas, as populações 4, 9 e 10 destacam-se se como de maior potencial para estudos genéticos e de melhoramento.The aim of this work was to evaluate the phenotypic diversity of Campomanesia adamantium based on the morphological characteristics and seed emergence in ten populations from Cerrado (sensu stricto) area, in Dourados-MS. The establishment of coordinates of every population was obtained as a function of phenotypic difference showed among them, distributed in an area of 32 ha. Collect of fruits were done in the second period of fifteen days of December, 2009, fruitful period of the specie. For biometry study, a complete randomized experimental design was used, with ten treatments, which corresponded to populations and ten replications of ten fruits, which corresponded to experimental units. Germinative behavior study of seeds was carried out in green house conditions and use randomized block design, with four replications of sixteen seeds, as experimental unit, for every population. In biometry study of fruits and in germinative behavior of seeds, it was observed the presence of groups statistically different for every evaluated characteristic. Populations of C. adamantium, in native area, showed fruits with high phenotypic variability. In green house, seedlings by seed propagation showed a small proportion of phenotypic diversity. Considering characteristics of fruits and propagatives, populations 4, 9 and 10 are outstanding as the highest potential for genetic studies and for improvement.Facultad de Ciencias Agrarias y Forestale

    Background and aims Primary dyslipidemias are a heterogeneous group of disorders characterized by abnormal levels of circulating lipoproteins. Among them, familial hypercholesterolemia is the most common lipid disorder that predisposes for premature cardiovascular disease. We set up an Italian nationwide network aimed at facilitating the clinical and genetic diagnosis of genetic dyslipidemias named LIPIGEN (LIpid TransPort Disorders Italian GEnetic Network). Methods Observational, multicenter, retrospective and prospective study involving about 40 Italian clinical centers. Genetic testing of the appropriate candidate genes at one of six molecular diagnostic laboratories serving as nationwide DNA diagnostic centers. Results and conclusions From 2012 to October 2016, available biochemical and clinical information of 3480 subjects with familial hypercholesterolemia identified according to the Dutch Lipid Clinic Network (DLCN) score were included in the database and genetic analysis was performed in 97.8% of subjects, with a mutation detection rate of 92.0% in patients with DLCN score \ue2\u89\ua56. The establishment of the LIPIGEN network will have important effects on clinical management and it will improve the overall identification and treatment of primary dyslipidemias in Italy

    We evaluated the effect of DMTs on Covid-19 severity in patients with MS, with a pooled-analysis of two large cohorts from Italy and France. The association of baseline characteristics and DMTs with Covid-19 severity was assessed by multivariate ordinal-logistic models and pooled by a fixed-effect meta-analysis. 1066 patients with MS from Italy and 721 from France were included. In the multivariate model, anti-CD20 therapies were significantly associated (OR = 2.05, 95%CI = 1.39–3.02, p < 0.001) with Covid-19 severity, whereas interferon indicated a decreased risk (OR = 0.42, 95%CI = 0.18–0.99, p = 0.047). This pooled-analysis confirms an increased risk of severe Covid-19 in patients on anti-CD20 therapies and supports the protective role of interferon

    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

    Differential cross section measurements for the production of a W boson in association with jets in proton–proton collisions at √s = 7 TeV

    Get PDF
    Measurements are reported of differential cross sections for the production of a W boson, which decays into a muon and a neutrino, in association with jets, as a function of several variables, including the transverse momenta (pT) and pseudorapidities of the four leading jets, the scalar sum of jet transverse momenta (HT), and the difference in azimuthal angle between the directions of each jet and the muon. The data sample of pp collisions at a centre-of-mass energy of 7 TeV was collected with the CMS detector at the LHC and corresponds to an integrated luminosity of 5.0 fb[superscript −1]. The measured cross sections are compared to predictions from Monte Carlo generators, MadGraph + pythia and sherpa, and to next-to-leading-order calculations from BlackHat + sherpa. The differential cross sections are found to be in agreement with the predictions, apart from the pT distributions of the leading jets at high pT values, the distributions of the HT at high-HT and low jet multiplicity, and the distribution of the difference in azimuthal angle between the leading jet and the muon at low values.United States.

Method in this stady use performance measuring of productivity, efficiency, growth, liquidity, and solvability of cooperative. Productivity of cooperative in Pelalawan was highly but efficiency still low. Profit and income were highly, even liquidity of cooperative very high, and solvability was good

    Search for stop and higgsino production using diphoton Higgs boson decays

    Get PDF
    Results are presented of a search for a "natural" supersymmetry scenario with gauge mediated symmetry breaking. It is assumed that only the supersymmetric partners of the top-quark (stop) and the Higgs boson (higgsino) are accessible. Events are examined in which there are two photons forming a Higgs boson candidate, and at least two b-quark jets. In 19.7 inverse femtobarns of proton-proton collision data at sqrt(s) = 8 TeV, recorded in the CMS experiment, no evidence of a signal is found and lower limits at the 95% confidence level are set, excluding the stop mass below 360 to 410 GeV, depending on the higgsino mass
