Ascogrammitis lehnertii (Polypodiaceae): a new and dominant understory-species from a diverse community of grammitid ferns in the Andes of Ecuador

In the scope of pantropical studies aimed at understanding how the diversity of grammitid ferns (Polypodiaceae) has evolved and is maintained, we studied a diverse grammitid community in treeline elfin forests in eight study plots of 400 m2 each at 3200 m on Cerro Toledo, Loja, southern Ecuador.Werecorded a total of 7986 individuals of 16 grammitid species. Ascogrammitis lehnertii is here described as a newspecies.We also recorded Mycopteris leucosticta, a species previously believed to be restricted to the Choc´o region of Ecuador. We found that the grammitid species were segregated by habitat into trunk-base and trunk specialists, which suggests that species coexistence in these diverse epiphytic communities is at least partly linked to habitat segregation. Ascogrammitis lehnertii and M. leucosticta were the second and third most abundant species, respectively, and both were mostly trunk-base species. The new species A. lehnertii differs from its congeners by the combination of its relatively broad lamina, (2–)3–4 cmwide, fertile leaves bearing 2mmlong reddish setae in and near the sori, and by bearing proliferous roots from which new plants emerge. Phylogenetic analyses of atpß, rbcL, rps4, trnG-trnR, andtrnL-trnFDNAmolecular sequences, usingmaximum likelihood, place A. lehnertii as sister to A. cuencana with strong support. Despite previous intensive collection efforts in Loja for the past 30 yr, all but one of the collections of this new species were made in the last three years. The discovery of A. lehnertii and the new record of M. leucosticta highlight the patchy distribution of some species in the Andes and the value of surveying

Calidad en el sector retail farmacéutico en la ciudad de Lima

La calidad así como su gestión han evolucionado en el mundo. En Perú no es ajeno a ello, y en lo que respecta a la gestión de la calidad de las empresas en Perú, se ha podido observar que existe una mejora significativa en su implementación. A partir de este contexto, se buscó medir el nivel de implementación de la gestión de la calidad en nueve factores de las empresas del Sector Retail Farmacéutico en la Ciudad de Lima, tomando como base a las cinco principales empresas que operan en el medio, siendo estas: (a) Inkafarma, (b) Mifarma, (c) Boticas Torres de Limatambo (BTL), (d) Farmacias Peruanas (FASA), y (e) Boticas Arcángel. La presente tesis buscó ampliar el conocimiento de la calidad en las cinco principales empresas del Sector Retail Farmacéutico mediante una investigación con un enfoque cuantitativo y un alcance descriptivo. Para la investigación se utilizó una herramienta de medición de la implementación de la gestión de la calidad basada en nueve factores: (a) Alta Gerencia, (b) Planeamiento de la Calidad, (c) Auditoría y Evaluación de la Calidad, (d) Diseño del Producto, (e) Gestión de la Calidad del Proveedor, (f) Control y Mejoramiento del Proceso, (g) Educación y Entrenamiento, (h) Círculos de Calidad, y (i) Enfoque hacia la Satisfacción del Cliente; utilizando para ello información de campo recopilada a través de una encuesta realizada en diversos establecimientos de las empresas indicadas. Los resultados han demostrado que no se han implementado factores de la administración de la calidad total en las empresas investigadas, sus actividades operativas se basan en: (a) cumplimiento de requisitos legales y regulatorios, (b) las buenas prácticas de distribución, y (c) las buenas prácticas de almacenamiento, impuestos por la DIGEMID interpretando estos requisitos como un sistema de gestión de calidad cuando en realidad no lo son.Quality and its management have evolved throughout the years and around the world. As a result, we are taking part in this process as the quality management of peruvian companies have improved in their implementation. Thus, I will measure the levels of quality management implementation of pharmaceutical retail sector companies based on five main ones that are currently operating: (a) Inkafarma, (b) Mifarma, (c) Boticas Torres de Limatambo (BTL), (d) Farmacias Peruanas (FASA), and (e) Boticas Arcángel. This thesis tried to extend the knowledge of quality in five pharmaceutical retail companies through an investigation with a quantitative approach and a descriptive scope. For this investigation it was used a measuring instrument for the quality management considering nine factors: (a) Senior Management, (b) Quality Planning, (c) Audit and Evaluation, (d) Product Design, (e) Supplier Quality Management, (f) Control and Improvement of the Process, (g) Education and Training, (h) Quality Circles, and (i) Approaches for Customer’s Satisfaction. All these were gathered by a field data that was compiled thanks to a survey made in different locations of the companies. The results have shown that the researched companies have not used the total quality management implementation. Their activities have their basis on: (a) the regulatory and legal requirements, (b) the good practices of distribution and storage imposed by the General Bureau for Medicines, Drugs, and Inputs (DIGEMID) as if they were a system of quality management implementation when they are not. This study represents a first approach of the reality in the pharmaceutical retail sector concerning systems of quality management as there is no previous information about this topic. Thus, it will be the basis for future studies and measure its evolution in time.Tesi

Children’s and adolescents’ rising animal-source food intakes in 1990–2018 were impacted by age, region, parental education and urbanicity

Animal-source foods (ASF) provide nutrition for children and adolescents’ physical and cognitive development. Here, we use data from the Global Dietary Database and Bayesian hierarchical models to quantify global, regional and national ASF intakes between 1990 and 2018 by age group across 185 countries, representing 93% of the world’s child population. Mean ASF intake was 1.9 servings per day, representing 16% of children consuming at least three daily servings. Intake was similar between boys and girls, but higher among urban children with educated parents. Consumption varied by age from 0.6 at <1 year to 2.5 servings per day at 15–19 years. Between 1990 and 2018, mean ASF intake increased by 0.5 servings per week, with increases in all regions except sub-Saharan Africa. In 2018, total ASF consumption was highest in Russia, Brazil, Mexico and Turkey, and lowest in Uganda, India, Kenya and Bangladesh. These findings can inform policy to address malnutrition through targeted ASF consumption programmes.publishedVersio

Incident type 2 diabetes attributable to suboptimal diet in 184 countries

The global burden of diet-attributable type 2 diabetes (T2D) is not well established. This risk assessment model estimated T2D incidence among adults attributable to direct and body weight-mediated effects of 11 dietary factors in 184 countries in 1990 and 2018. In 2018, suboptimal intake of these dietary factors was estimated to be attributable to 14.1 million (95% uncertainty interval (UI), 13.8–14.4 million) incident T2D cases, representing 70.3% (68.8–71.8%) of new cases globally. Largest T2D burdens were attributable to insufficient whole-grain intake (26.1% (25.0–27.1%)), excess refined rice and wheat intake (24.6% (22.3–27.2%)) and excess processed meat intake (20.3% (18.3–23.5%)). Across regions, highest proportional burdens were in central and eastern Europe and central Asia (85.6% (83.4–87.7%)) and Latin America and the Caribbean (81.8% (80.1–83.4%)); and lowest proportional burdens were in South Asia (55.4% (52.1–60.7%)). Proportions of diet-attributable T2D were generally larger in men than in women and were inversely correlated with age. Diet-attributable T2D was generally larger among urban versus rural residents and higher versus lower educated individuals, except in high-income countries, central and eastern Europe and central Asia, where burdens were larger in rural residents and in lower educated individuals. Compared with 1990, global diet-attributable T2D increased by 2.6 absolute percentage points (8.6 million more cases) in 2018, with variation in these trends by world region and dietary factor. These findings inform nutritional priorities and clinical and public health planning to improve dietary quality and reduce T2D globally.publishedVersio

Search for dark matter produced in association with bottom or top quarks in √s = 13 TeV pp collisions with the ATLAS detector

A search for weakly interacting massive particle dark matter produced in association with bottom or top quarks is presented. Final states containing third-generation quarks and miss- ing transverse momentum are considered. The analysis uses 36.1 fb−1 of proton–proton collision data recorded by the ATLAS experiment at √s = 13 TeV in 2015 and 2016. No significant excess of events above the estimated backgrounds is observed. The results are in- terpreted in the framework of simplified models of spin-0 dark-matter mediators. For colour- neutral spin-0 mediators produced in association with top quarks and decaying into a pair of dark-matter particles, mediator masses below 50 GeV are excluded assuming a dark-matter candidate mass of 1 GeV and unitary couplings. For scalar and pseudoscalar mediators produced in association with bottom quarks, the search sets limits on the production cross- section of 300 times the predicted rate for mediators with masses between 10 and 50 GeV and assuming a dark-matter mass of 1 GeV and unitary coupling. Constraints on colour- charged scalar simplified models are also presented. Assuming a dark-matter particle mass of 35 GeV, mediator particles with mass below 1.1 TeV are excluded for couplings yielding a dark-matter relic density consistent with measurements

Search for diboson resonances with boson-tagged jets in pp collisions at √s=13 TeV with the ATLAS detector

Narrow resonances decaying into WW, WZ or ZZ boson pairs are searched for in 36.7 fb−1 of proton–proton collision data at a centre-of-mass energy of √s=13 TeV recorded with the ATLAS detector at the Large Hadron Collider in 2015 and 2016. The diboson system is reconstructed using pairs of large-radius jets with high transverse momentum and tagged as compatible with the hadronic decay of high-momentum W or Z bosons, using jet mass and substructure properties. The search is sensitive to diboson resonances with masses in the range 1.2–5.0 TeV. No significant excess is observed in any signal region. Exclusion limits are set at the 95% confidence level on the production cross section times branching ratio to dibosons for a range of theories beyond the Standard Model. Model-dependent lower limits on the mass of new gauge bosons are set, with the highest limit set at 3.5 TeV in the context of mass-degenerate resonances that couple predominantly to bosons
