    This work provides a first assessment of the possible barrier effect of the Pyrenees on the atmospheric transport of airborne pollen from Europe to the North of the Iberian Peninsula. Aerobiological data recorded in three Spanish stations located at the eastern, central and western base of the Pyrenees in the period 2004–2014 have been used to identify the possible long range transport episodes of Betula pollen. The atmospheric transport routes and the origin regions have been established by means of trajectory analysis and a source receptor model. Betula pollen outbreaks were associated with the meteorological scenario characterized by the presence of a high-pressure system overm over Morocco and Southern Iberian Peninsula. France and Central Europe have been identified as the probable source areas of Betula pollen that arrives to Northern Spain. However, the specific source areas are mainly determined by the particular prevailing atmospheric circulation of each location. Finally, the Weather Research and Forecasting model highlighted the effect of the orography on the atmospheric transport patterns, showing paths through the western and easternmost lowlands for Vitoria-Gasteiz and Bellaterra respectively, and the direct impact of air flows over Vielha through the Garona valley.Peer ReviewedPreprin

    Hourly measurements of pollen near-surface concentration and lidar-derived profiles of particle backscatter coefficients and of volume and particle depolarization ratios during a 5-day pollination event observed in Barcelona, Spain, between 27 – 31 March, 2015, are presented. Maximum hourly pollen concentrations of 4700 and 1200 m-3 h-1 were found for Platanus and Pinus, respectively, which represented together more than 80 % of the total pollen. Everyday a clear diurnal cycle caused by the vertical transport of the airborne pollen was visible on the lidar-derived profiles of the backscatter coefficient with maxima usually reached between 12 and 15 UT. A method based on the lidar polarization capabilities was used to retrieve the contribution of the pollen to the total signal. On average the diurnal (9 – 17 UT) pollen aerosol optical depth (AOD) was 0.05 which represented 29 % of the total AOD, the volume and particle depolarization ratios in the pollen plume were 0.08 and 0.14, respectively, and the diurnal mean of the height of the pollen plume was found at 1.24 km. The dispersion of the Platanus and Pinus in the atmosphere was simulated with the Nonhydrostatic Multiscale Meteorological Model on the B grid at the Barcelona Supercomputing Center with a newly developed Chemical Transport Model (NMMB/BSC-CTM). Model near-surface daily concentrations were compared to our observations at two sites: in Barcelona and Bellaterra (12 km NE of Barcelona). Model hourly concentrations were compared to our observations in Barcelona.Peer ReviewedPostprint (author's final draft

    The micro and small business sector, an economic basis of popular levels, contributes about 40% of national GDP, which is why Peru is said to be a country of entrepreneurs, and is considered among the largest in Latin America. Until a few years ago MYPEs were only led by men, female participation in leadership roles was not widely perceived. They were known to be a fundamental pillar in the design, implementation and development of entrepreneurship, but always taking a step aside in labor leadership activities. Today, however, women are actively involved in this economic sector. According to (INEI, 2015), figures, seven out of ten women work in micro-enterprises. Jobs are distributed in the services sector (40.5%), in the trade sector (25.6%), in the agriculture sector (22.3%), in the manufacturing sector (8.6%), in the transport and communications sector (1.99%). The fact that in order to know something factual about this economic sector in terms of women's participation in the conduct of these organizations, is that this article is formulated, in order to observe MYPES representative of different economic sectors of the Cusco District in 2019, and develop a set of ideas that can help answer the question of how can we build labor leadership with gender equity in this economic sector? , exploratorily identify the profile of people who already exercise the leadership position and know their expectations of personal and business development within a conceptual framework of gender focus, in organizations that are led by women. To this end, non-experimental research of a descriptive and analytical level and non-probabilistic sampling was designed, which had the case method to analyze information from primary sources. And as a propositional contribution we include a model of female leadership for MYPES in the geographical field chosen.  El sector de la micro y pequeña empresa, base económica de los niveles populares, contribuye con cerca del 40% del PBI nacional, y por ello se dice que el Perú es un país de emprendedores, y está considerado entre los mayores en Latinoamérica. Hasta hace unos años atrás las MYPEs solo eran liderados por los hombres, la participación femenina en roles de liderazgo no se percibía mucho. Se sabía que eran pilar fundamental en la concepción, implementación y desenvolvimiento del emprendimiento, pero siempre dando un paso al costado en actividades de liderazgo laboral. Sin embargo, en la actualidad las mujeres participan activamente en ese sector económico. Según cifras del  (INEI, 2015)siete de cada diez mujeres trabajan en microempresas. Los empleos se distribuyen en el sector servicios (40.5%), en el sector comercio (25.6%), en el sector agricultura (22.3%), en el sector manufactura (8.6%), en el sector transporte y comunicaciones (1.99%). De allí que en aras de conocer algo factual de este sector económico en cuanto a la participación de la mujer en la conducción de estas organizaciones, es que se formula este artículo, con la finalidad de observar MYPES representativas de diferentes sectores económicos del Distrito del Cusco el 2019, y desarrollar un conjunto de ideas que puedan contribuir a responder a la pregunta de ¿cómo se puede construir liderazgo laboral con equidad de género en este sector económico?, identificar exploratoriamente el perfil de las personas que ya ejercen la posición de liderazgo y conocer sus expectativas de desarrollo personal y empresarial dentro de un marco conceptual de enfoque de género, en las organizaciones que se hallan dirigidas por mujeres. Para ello se diseñó una investigación no experimental de nivel descriptivo y analítico y muestreo no probabilístico, que contó con el método de casos para analizar la información de fuentes primarias. Y como aporte propositivo incluimos un modelo de liderazgo femenino para las MYPES del ámbito geográfico elegido

    Introduction: The incidence of thyroid cancer has increased worldwide. Peru has few reports describing the national and regional epidemiology of thyroid cancer. Objective: The incidence of thyroid cancer has increased worldwide. Peru has few reports describing the national and regional epidemiology of thyroid cancer. Methods: A descriptive study of trends was conducted with secondary data obtained from a public information source in Peru. The ICD 10: C73.0 coding record was evaluated, by age group, year and region. The age-standardized prevalence (period 2005 to 2016) and mortality (period 2005 to 2015) were calculated by region and year of study. Results: In the 2005-2016 period, 19 513 cases of thyroid cancer were recorded. The age group with the highest frequency was 30 to 59 years (57.7%). The prevalence increased from 4.7 to 15.2 cases per 100 000 inhabitants in the period 2005-2016, with the coastal region showing the greatest increase. Likewise, 1596 deaths from thyroid cancer (period 2005 to 2015) were recorded, more frequently in those older than 60 years (75.5%). The age-standardized mortality rate increased from 0.67 in 2005 to 0.72 in 2015, being the highlands the one with the greatest increase. Conclusions: The prevalence of thyroid cancer increased and mortality remained constant in the period studied. These results suggest exploring social and population factors that may have influenced these results. Likewise, population records of this and other neoplasms in Peru should be improved

    Resumen Introducción La incidencia de cáncer de tiroides se ha incrementado en el mundo. En Perú existen limitados informes que describan la epidemiología nacional y regional de esta neoplasia. Objetivo Describir la tendencia de la prevalencia y mortalidad de cáncer de tiroides registrada en el Ministerio de Salud de Perú. Métodos Se realizó un estudio descriptivo de tendencias con datos secundarios, obtenidos de una fuente de información pública de Perú. Se evaluó el registro de codificación CIE 10: C73.0, por grupo de edad, año y región. Se calcularon las tasas estandarizadas de la prevalencia (periodo 2005 a 2016) y mortalidad (periodo 2005 a 2015) por regiones y año de estudio. Resultados Durante el periodo 2005-2016 se registraron 19 513 casos de cáncer de tiroides. El grupo etario con mayor frecuencia fue de 30 a 59 años (57,7%). La prevalencia incrementó de 4,7 a 15,2 casos por 100 000 habitantes en el periodo 2005-2016 y la región de la costa fue la que presentó mayor ascenso. Asimismo, se registraron 1596 muertes por cáncer de tiroides (periodo 2005 a 2015) con mayor frecuencia en mayores de 60 años (75,5%). La tasa estandarizada de mortalidad por 100 000 habitantes aumentó de 0,67 en 2005 a 0,72 en 2015, siendo la región de la sierra la de mayor incremento. Conclusiones La prevalencia por cáncer de tiroides aumentó y la mortalidad se mantuvo constante en el periodo estudiado. Estos resultados animan a explorar factores sociales y de la población que hayan podido influir en ello; además de mejorar los registros poblacionales de esta y otras neoplasias en Perú
