    Actualmente el diseño urbano de la ciudad no está pensado como un modelo de ciudad incluyente, en el que las personas con movilidad reducida tengan las mismas oportunidades de desenvolverse, tanto en el espacio público como al interior de las edificaciones. Esto evidencia un importante desconocimiento y descuido de la proyección y diseño de la ciudad, cohibiéndolos de participar activamente en la sociedad y del desarrollo integral de la persona. Por esto mismo se busca desarrollar una modelación que mejore y organice las condiciones y componentes del espacio público en cada una de las escalas: metropolitana, urbana y local. El modelo buscará intervenir el espacio a partir del flujo y de las actividades urbanas para aumentar la participación y autonomía de las personas con movilidad reducida.At present the urban design of the city is not intended as an inclusive city model, in which people with reduced mobility have the same opportunities to develop, both in the public space and inside the buildings. This shows an important ignorance and neglect of the projection and design of the city, inhibiting them from actively participating in society and the integral development of the person. For this reason, it seeks to develop a model that improves and organizes the conditions and components of public space in each of the scales: metropolitan, urban and local. The model will seek to intervene space from the flow and urban activities to increase the participation and autonomy of people with reduced mobility.Arquitecto (a)Pregrad

    Haemoglobin and haematocrit: the threefold conversion is also non valid for assessing anaemia in Plasmodium vivax malaria-endemic settings

    Get PDF
    It has been recently reported that the standard threefold conversion from haematocrit to haemoglobin underestimates the prevalence of anaemia and low levels of haemoglobin in children living in areas endemic for Plasmodium falciparum malaria. The data presented herein describes the experience in a malaria-endemic zone in northeastern Venezuela (state of Sucre), where a similar bias between haematocrit and haemoglobin in patients with Plasmodium vivax infection was found. In summary, the relationship between haematocrit and haemoglobin needs to be specifically evaluated according to each particular region or epidemiological setting

    Food practices in schoolchildren show a high prevalence of sugar consumption. The objective of the study was to describe the prevalence of cavities, nutritional habits in preschoolers and first and to promote healthy eating practices at the school Ciudadela Nuevo Occidente. Materials and methods: A descriptive study was carried out with the participation of 61 boys and girls of the preschool, first and second grade, 80 parents or representatives and a non-participant observation was made to schoolchildren, school store and innkeepers, to explore the habits of food consumption in the Institution. Finally, a playful educational strategy was implemented that promoted healthy eating practices. A descriptive analysis of the information collected, and a bivariate analysis were carried out to compare the findings within the study period. The development study during the period 2017-II and 2019-II. Results: 60% of the respondents belonged to a level 1 socioeconomic stratum, 61% of parents had complete and incomplete secondary schooling. 58.8% have a daily consumption of sweets and soft drinks. The frequency of caries was 47.5% and white spots was 49.1%. Cariogenic foods are in the environment of children. 18 educational activities were carried out with 160 preschool and first school children and their teachers. Conclusions: practices such as high sugar intake, poor brushing, not packing children’s toothbrush for school,are risk factors that expose schoolchildren to cavities.Las prácticas alimentarias en escolares, muestran una alta prevalencia del consumo azucares.

El proceso de la catedra se orientó con la metodología MARDIC, la cual propicio la participación activa de grupos organizados denominados grupos focales.Universidad Libre Seccional Pereir

    Sloan Digital Sky Survey IV: mapping the Milky Way, nearby galaxies, and the distant universe

    Get PDF
    We describe the Sloan Digital Sky Survey IV (SDSS-IV), a project encompassing three major spectroscopic programs. The Apache Point Observatory Galactic Evolution Experiment 2 (APOGEE-2) is observing hundreds of thousands of Milky Way stars at high resolution and high signal-to-noise ratios in the near-infrared. The Mapping Nearby Galaxies at Apache Point Observatory (MaNGA) survey is obtaining spatially resolved spectroscopy for thousands of nearby galaxies (median ). The extended Baryon Oscillation Spectroscopic Survey (eBOSS) is mapping the galaxy, quasar, and neutral gas distributions between and 3.5 to constrain cosmology using baryon acoustic oscillations, redshift space distortions, and the shape of the power spectrum. Within eBOSS, we are conducting two major subprograms: the SPectroscopic IDentification of eROSITA Sources (SPIDERS), investigating X-ray AGNs and galaxies in X-ray clusters, and the Time Domain Spectroscopic Survey (TDSS), obtaining spectra of variable sources. All programs use the 2.5 m Sloan Foundation Telescope at the Apache Point Observatory; observations there began in Summer 2014. APOGEE-2 also operates a second near-infrared spectrograph at the 2.5 m du Pont Telescope at Las Campanas Observatory, with observations beginning in early 2017. Observations at both facilities are scheduled to continue through 2020. In keeping with previous SDSS policy, SDSS-IV provides regularly scheduled public data releases; the first one, Data Release 13, was made available in 2016 July

    Search for new particles in events with energetic jets and large missing transverse momentum in proton-proton collisions at root s=13 TeV

    Get PDF
    A search is presented for new particles produced at the LHC in proton-proton collisions at root s = 13 TeV, using events with energetic jets and large missing transverse momentum. The analysis is based on a data sample corresponding to an integrated luminosity of 101 fb(-1), collected in 2017-2018 with the CMS detector. Machine learning techniques are used to define separate categories for events with narrow jets from initial-state radiation and events with large-radius jets consistent with a hadronic decay of a W or Z boson. A statistical combination is made with an earlier search based on a data sample of 36 fb(-1), collected in 2016. No significant excess of events is observed with respect to the standard model background expectation determined from control samples in data. The results are interpreted in terms of limits on the branching fraction of an invisible decay of the Higgs boson, as well as constraints on simplified models of dark matter, on first-generation scalar leptoquarks decaying to quarks and neutrinos, and on models with large extra dimensions. Several of the new limits, specifically for spin-1 dark matter mediators, pseudoscalar mediators, colored mediators, and leptoquarks, are the most restrictive to date.Peer reviewe

    Measurement of prompt open-charm production cross sections in proton-proton collisions at root s=13 TeV

    Get PDF
    The production cross sections for prompt open-charm mesons in proton-proton collisions at a center-of-mass energy of 13TeV are reported. The measurement is performed using a data sample collected by the CMS experiment corresponding to an integrated luminosity of 29 nb(-1). The differential production cross sections of the D*(+/-), D-+/-, and D-0 ((D) over bar (0)) mesons are presented in ranges of transverse momentum and pseudorapidity 4 < p(T) < 100 GeV and vertical bar eta vertical bar < 2.1, respectively. The results are compared to several theoretical calculations and to previous measurements.Peer reviewe
