    ABSTRACTA case report of a 19-year-old female patient who attended the Orthodontics Department, Faculty of Dentistry, National Autonomous University of Mexico without any apparent pathological data is hereby presented. Upon interrogation, the patient referred to have had a previous surgical replacement of the left ear lobe. Physical examination revealed a severe facial asymmetry with mandibular deviation to the left side, straight profile, upper lip retrusion and gibbous nose. Intraorally the patient showed crowding, non-coincident dental midlines, squared arches and class III molar and canine relationship with left crossbite. Radiographically all dental organs were present and mandibular asymmetry could be observed. Cephalometric analysis showed skeletal a class III due to maxillary retrusion, vertical growth pattern, left laterognathia, proclination of upper incisors and upper lip retrusion. Treatment consisted of three phases: 1 presurgical orthodontics with 0.018” slot Alexander appliances and an archwire sequence suitable to the problem that the patient presented. Subsequently, surgical phase 2 was initiated with a sagittal osteotomy for bilateral laterognathia correction. During phase 3, postsurgical orthodontics, the case was detailed, muscular patterns were corrected and the occlusion was settled. Treatment was completed in 36 months. The profile and facial harmony were improved, the positive smile was maintained and the crossbite corrected. Bilateral canine and molar class I was obtained, the dental midlines were centered and arch form was improved as were the overbite and overjet

    Valoración económica de humedales: casos Capellanía y La Conejera

    Los humedales son indispensables en la sostenibilidad de sus territorios circundantes. Como resultado de las presiones urbanas, Bogotá ha experimentado un rápido deterioro y desaparición tidisciplinar los servicios ecosistémicos de los humedales Capellanía y La Conejera en las localidades de Fontibón y Suba respectivamente. Los resultados muestran que, a pesar del deterioro, estos dos ecosistemas siguen generando externalidades positivas a las comunidades vecinas, las cuales muestran una disposición a pagar positiva para su recuperación y protección. En términos de la calidad del agua, los análisis indican niveles preocupantes de contaminación especialmente en las áreas de influencia de actividades industriales en ambos casos. Frente a la avifauna, el trabajo de campo indica que las actividades de recuperación realizadas por la comunidad de los ecosistemas han hecho posible el retorno de algunas especies y la estabilidad de especies endémicas como el rascón bogotano.

    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

    Measurement of the Splitting Function in &ITpp &ITand Pb-Pb Collisions at root&ITsNN&IT=5.02 TeV

    Get PDF
    Data from heavy ion collisions suggest that the evolution of a parton shower is modified by interactions with the color charges in the dense partonic medium created in these collisions, but it is not known where in the shower evolution the modifications occur. The momentum ratio of the two leading partons, resolved as subjets, provides information about the parton shower evolution. This substructure observable, known as the splitting function, reflects the process of a parton splitting into two other partons and has been measured for jets with transverse momentum between 140 and 500 GeV, in pp and PbPb collisions at a center-of-mass energy of 5.02 TeV per nucleon pair. In central PbPb collisions, the splitting function indicates a more unbalanced momentum ratio, compared to peripheral PbPb and pp collisions.. The measurements are compared to various predictions from event generators and analytical calculations.Peer reviewe

    Measurement of nuclear modification factors of gamma(1S)), gamma(2S), and gamma(3S) mesons in PbPb collisions at root s(NN)=5.02 TeV

    The cross sections for ϒ(1S), ϒ(2S), and ϒ(3S) production in lead-lead (PbPb) and proton-proton (pp) collisions at √sNN = 5.02 TeV have been measured using the CMS detector at the LHC. The nuclear modification factors, RAA, derived from the PbPb-to-pp ratio of yields for each state, are studied as functions of meson rapidity and transverse momentum, as well as PbPb collision centrality. The yields of all three states are found to be significantly suppressed, and compatible with a sequential ordering of the suppression, RAA(ϒ(1S)) > RAA(ϒ(2S)) > RAA(ϒ(3S)). The suppression of ϒ(1S) is larger than that seen at √sNN = 2.76 TeV, although the two are compatible within uncertainties. The upper limit on the RAA of ϒ(3S) integrated over pT, rapidity and centrality is 0.096 at 95% confidence level, which is the strongest suppression observed for a quarkonium state in heavy ion collisions to date. © 2019 The Author(s).
