Anthropometric measures as predictive indicators of metabolic risk in a population of “holy week costaleros”

Preventive measures are a priority in those groups that perform intense physical efforts without physical preparation and that can also be overweight or obese. One of the groups that reflect these characteristics is the costaleros of the Holy Week of Andalusia, Spain. This paper aims to describe the effect of obesity on blood pressure. A descriptive cross-sectional study was conducted on 101 costaleros. The anthropometric measures were determined through segmental impedance. Cardiac recovery and anaerobic power were measured through the Ruffier–Dickson test and the Abalakov test, respectively. Blood pressure was measured when the individuals were at rest. The Kruskal–Wallis test was applied for of continuous parameters and the X2 test for dichotomous measures. Binary logistic regression models were used for the subsequent analysis with R-square and Receiver Operating Characteristic (ROC) curves. The average population was 28 years of age, 173.7 cm tall, and 82.59 Kg weigh. The excess of body fat was 11.27 Kg and Body Mass Index was 27.33 Kg/m2. 72.3% showed abnormal blood pressure and 68.2% were overweight. 32.7% had a waist-hip ratio higher than 0.94. The probability of presenting abnormal blood pressure was higher among the subjects whose fat content was higher and muscle content was lower

The validity of Rhetorical categories in audiovisual culture

Los ámbitos de la comunicación, la sociedad y el arte han evolucionado como consecuencia de los cambios culturales y del progreso de las nuevas tecnologías. Sin embargo, en la cultura audiovisual dominante hoy, la Retórica clásica sigue vigente y ha sabido adaptarse a los nuevos modelos de comunicación que integran elementos visuales, lingüísticos y acústicos que pueden ser analizados y entendidos a través de la Retórica CulturalCommunication, Society, and Art evolve as a consequence of cultural change and new technologies’ development. However, in current audiovisual mainstream Culture, Classical Rhetoric is still useful. It adapts itself to new communicative models incorporating visual, linguistic, and acoustic elements, which can be studied and understood through Cultural RhetoricEste trabajo es resultado de la investigación realizada en el proyecto METAPHORA (Referencia FFI2014-53391-P), proyecto de investigación financiado por la Secretaría de Estado de Investigación, Desarrollo e Innovació

SCHC includes acknowledgment (ACK)-based mechanisms for reliable fragmented packet transmission. For the latter, SCHC defines a Receiver-Feedback Technique (RFT), called Compressed Bitmap (CB), by which a receiver reports to the sender whether the fragments carrying a packet have been received or not. Such information is carried as ACK payload. Considering the extraordinary frame size and message rate constraints of LPWANs, ACK payload size becomes crucial. In this paper, we compare the performance of CB with that of several alternative RFTs, namely List of Lost Fragments (LLF), List of Deltas (LoD), and Uncompressed Bitmap (UB), where the latter is used as a benchmark. We evaluate the considered RFTs in terms of ACK size, number of Layer 2 (L2) frames needed to carry an ACK, and ACK Time on Air. Our analysis shows that the use of RFTs different from CB offers significant performance improvement in many scenarios. Furthermore, we provide guidance on which RFT should be used for different packet sizes, error rates and error patterns.This research is funded in part by the ERDF and the Spanish Government through project TEC2016-79988-P and project PID2019-106808RA-I00, AEI/FEDER, EU.Peer ReviewedPostprint (author's final draft

Basket-Handle Arch and Its Optimum Symmetry Generation as a Structural Element and Keeping the Aesthetic Point of View

The arches were a great advance in construction with respect to the rigid Greek linteled architecture. Its development came from the hand of the great Roman constructions, especially with the semicircular arch. In successive historical periods, different types of arches have been emerging, which in addition to their structural function was taking aesthetic characteristics that are used today to define the architectural style. When, in the construction of a bow, the rise is less than half the springing line, the semicircular arch is no longer used and the segmental arch is used, and then on to another more efficient and aesthetic arch, the basket-handle arch. This study examines the classic geometry of the basket-handle arch also called the three-centered arch. A solution is proposed from a constructive and aesthetic point of view, and this is approached both geometrically and analytically, where the relationship between the radius of the central arch and the radius of the lateral arch is minimized. The solution achieved allows the maximum springing line or clear span to be saved with the minimum rise that preserves the aesthetic point of view, since the horizontal thrust of a bow is greater than the relationship between the springing line of the arch and the rise. This solution has been programmed and the resulting software has made it possible to analyse existing arches in historic buildings or constructions to check if their solutions were close or not from both points of view. Thus, it has been possible to verify that in most of the existing arches analyzed, the proposed solution is reached

Atrium impact on a school-building: thermal performance in a hot climate

The process of climate change has increased the planet’s mean temperature. An example of this are the 44.3 °C registered in July in the cities of Córdoba and Seville (Spain). In this scenario, the educational centers in Andalusia, mostly built during the 20th century, are unable to reach the thermal comfort inside the classrooms throughout the year, without resorting to mechanical air conditioning procedures. This study simultaneously monitors indoors, outdoors and transitional spaces of a case study to verify the effectiveness of the passive cooling systems and the Atrium thermal effect of the building. Our results demonstrate that temperatures inside classrooms are influenced by the orientation and their air circulation (atrium or outdoor) and as expected, the higher temperature in the building are registered in the classrooms in the last floor

Promoting light hydrocarbons yield by catalytic hydrodechlorination of residual chloromethanes using palladium supported on zeolite catalysts

Gas catalytic hydrodechlorination (HDC) of trichloromethane (TCM) and dichloromethane (DCM) was analyzed using Pd (1 wt.%) on different zeolites as catalysts. The aim of this study was to know the surface properties of the catalysts and reaction conditions that promote the yield to light hydrocarbons in this reaction. Five different zeolite supports were used from three commercial zeolites (KL, L-type; NaY, Faujasite; H-MOR, Mordenite). KL and NaY were submitted to ionic exchange treatments in order to increase their acidity and analyze the effect of the acidity in the activity and selectivity of the HDC reaction. Exchanged zeolites (HL and HY) showed the highest Pd dispersion due to their higher surface acidity. The best TCM/DCM conversion and selectivity to light hydrocarbons was obtained using the two non-exchanged zeolite-catalysts, KL and NaY. Low surface acidity seems to be the key aspect to promote the formation of light hydrocarbons. The formation of these products is favored at high reaction temperatures and low H2: chloromethane ratios. KL showed the highest selectivity to olefins (60%), although with a lower dechlorination degree. Non-exchanged NaY catalyst showed high selectivity to paraffins (70% and 95% for the HDC of DCM and TCM, respectively)Authors gratefully acknowledge financial support from FEDER/Ministerio de Ciencia, Innovación y Universidades—Agencia Estatal de Investigación/ CTM2017-85498-R.

The logarithmic spiral, autoisoptic curve

In the Line of Investigation that in the department of “Technical Drawing” in the School of Agriculture Engineering of Madrid, we carry out on the study of The Technical Curves and his singularities, we demonstrate an interesting property of the Logarithmic Spiral. The demonstrated property consists of which the logarithmic spiral is a autoisoptic curve, that is to say that if from a point P anyone of the spiral tangent straight lines draw up to the previous arc, these form a constant angle α. This demonstration is novel and in addition we get to contribute a method to calculate the angle α given the equation of the spiral

Creación de un departamento de mercadotecnia para mejorar la imagen corporativa y atraer financiamiento en la “Fundación Campo”, ubicada en el departamento de San Miguel.

Fundación Campo es una organización sin fines de lucro fundada en el año de 1995; es de nacionalidad salvadoreña, de utilidad pública, sin fines de lucro, sin posición políticopartidaria, ni religiosa, que tiene como finalidad desarrollar programas, proyectos y actividades que beneficien y mejoren la situación socio económica de las familias rurales. Actualmente la organización se encuentra en una posición de constante crecimiento en cuanto a desarrollo de proyectos de beneficio comunitario en toda la zona oriental, principalmente en el departamento de San Miguel, en aquellos municipios que se ven más afectados por la desigualdad social, por la falta de oportunidades, por la pobreza en general. La investigación realizada con el objetivo de diseñar un departamento de mercadotecnia se debe a la importancia que tiene hoy en día el diseñar e innovar constantemente la forma en la que las empresas se dan a conocer en el mercado, ya sean estas con o sin fines de lucro. Fundación Campo no es la excepción ya que al ser una institución que destina sus esfuerzos y emplea la totalidad de sus recursos en contribuir al desarrollo auto sostenible de cada una de las comunidades en las que interviene, debe de venderse para con cada una de las organizaciones ya sean estas estatales, privadas, nacionales o extranjeras que brindan apoyo tanto económico como técnico para el desarrollo de programas como los que ejecuta la fundación. En ese sentido, la Fundación necesita crear programas de diseño de estrategias que le permitan darse a conocer por cada institución de la cual esta pueda recibir apoyo económico y técnico que le facilite el desarrollo de cada uno de sus programas. 105 Por lo anterior, se hace de vital importancia el desarrollar una investigación que ayude a determinar factores que podrían servir como desarrollo del Departamento de Mercadotecnia, los mismo servirán de guía para desarrollar métodos que le permitan conseguir un posicionamiento firme delante de sus competidores para la obtención de recursos. Para concretar la consecución de la información necesaria para el desarrollo de este proyecto será necesaria la utilización de métodos de recolección de datos, los cuales servirán como base para conocer los principales factores de incidencia tanto positiva como negativamente en la organización. No obstante a lo anterior, antes de tomar cualquier decisión estratégica es imprescindible realizar un diagnóstico de la organización, con el fin de conocer la situación actual de la misma, esto tanto en forma interna como externa, lo cual servirá de base para conocer el mejor rumbo que esta debe tomar para la consecución de sus objetivos estratégicos. La creación de un departamento de mercadotecnia generará los medios necesarios para lograr que la organización cuente con estrategias de marketing que le permitan hacerle frente a las distintas adversidades que dentro del mercado puedan ocasionar dificultades tanto económicas como de cualquier otra índole
