Design and construction of a device for obtaining three-dimensional coordinates in different topographic surfaces through the use of wireless networks, GPS and altimeter

The present investigation is done through processes that permit to find the value of the unknown term “R”. The procedure for data collection disposed the transmitter and the receptor two meters apart, measuring the value of the parameter RSSI a total of twenty times; repeating this process every two meters, until the forty meters. The procedure for data collection disposed the transmitter and the receptor two meters apart, measuring the value of the parameter RSSI a total of twenty times; repeating this process every two meters, until the forty meters. In relation to the statistical treatment of the data, there were applied dispersion measurements or variability of the sample, such as the sample’s variation, the standard deviation of the sample and the error. The results established the existence of the relation between the two principal variables involved in the study. Potency (dBm) as independent variable and the distance as dependent variable, in conclusion, this is prove that the bigger the distance between the transmitter and the receptor is, the less power it expresses

Life-Threatening Acute Pulmonary Thromboembolism Following Severe Carbon Monoxide Poisoning

A 57-year-old man admitted with severe carbon monoxide (CO) poisoning suffered life-threatening pulmonary embolism (PE) after hyperbaric oxygen therapy, in the absence of other risk factors for thromboembolism, and was successfully treated with thrombolysis. CO is a thrombophilic condition predisposing to PE and active surveillance is advisable. (Level of Difficulty: Advanced.

Optimización Difusa Multiobjetiva en la Planificación de un Sistema de Generación de Energía Eólica

En este trabajo se formula un modelo de optimización multiobjetiva para la planificación de un centro de generación eólica que maximiza el ingreso y minimiza los desequilibrios de los costos de oferta. La estrategia de la solución que se utiliza está basada en la teoría de optimización difusa, en la que se utiliza la función de pertenencia linea

Evaluación de riesgo por sismo en el centro histórico de Huaraz, distrito de Huaraz, Huaraz - Ancash

El objetivo es identificar el peligro, la vulnerabilidad y el riesgo del centro histórico de Huaraz debido a la ocurrencia de un sismo. Mediante el uso del manual para la evaluación de riesgos originados por fenómenos naturales en su segunda versión elaborada por el Centro Nacional de Estimación, Prevención y Reducción del Riesgo de Desastre (CENEPRED) se pudo determinar los niveles y mapas de peligro, vulnerabilidad y riesgo. Realizado el trabajo de campo se pudo obtener información de los factores, condicionantes y desencadenantes que fueron relacionados mediante el método multicriterio para un análisis semi cuantitativo, que influirán en los 152 lotes evaluados, fue así que se encontró que 70 lotes presentan un nivel de peligro muy alto y 82 lotes presentan un nivel de peligro alto. Además, se determinó que 55 lotes presentan vulnerabilidad muy alta, 84 lotes vulnerabilidad alta y 13 lotes vulnerabilidad media. La superposición del mapa de peligro y el mapa de vulnerabilidad determinó el riesgo sísmico, encontrándose que el 37% de lotes están en riesgo muy alto y el 63% de lotes están en riesgo alto

Antimicrobial resistance among migrants in Europe: a systematic review and meta-analysis

BACKGROUND: Rates of antimicrobial resistance (AMR) are rising globally and there is concern that increased migration is contributing to the burden of antibiotic resistance in Europe. However, the effect of migration on the burden of AMR in Europe has not yet been comprehensively examined. Therefore, we did a systematic review and meta-analysis to identify and synthesise data for AMR carriage or infection in migrants to Europe to examine differences in patterns of AMR across migrant groups and in different settings. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, PubMed, and Scopus with no language restrictions from Jan 1, 2000, to Jan 18, 2017, for primary data from observational studies reporting antibacterial resistance in common bacterial pathogens among migrants to 21 European Union-15 and European Economic Area countries. To be eligible for inclusion, studies had to report data on carriage or infection with laboratory-confirmed antibiotic-resistant organisms in migrant populations. We extracted data from eligible studies and assessed quality using piloted, standardised forms. We did not examine drug resistance in tuberculosis and excluded articles solely reporting on this parameter. We also excluded articles in which migrant status was determined by ethnicity, country of birth of participants' parents, or was not defined, and articles in which data were not disaggregated by migrant status. Outcomes were carriage of or infection with antibiotic-resistant organisms. We used random-effects models to calculate the pooled prevalence of each outcome. The study protocol is registered with PROSPERO, number CRD42016043681. FINDINGS: We identified 2274 articles, of which 23 observational studies reporting on antibiotic resistance in 2319 migrants were included. The pooled prevalence of any AMR carriage or AMR infection in migrants was 25·4% (95% CI 19·1-31·8; I2 =98%), including meticillin-resistant Staphylococcus aureus (7·8%, 4·8-10·7; I2 =92%) and antibiotic-resistant Gram-negative bacteria (27·2%, 17·6-36·8; I2 =94%). The pooled prevalence of any AMR carriage or infection was higher in refugees and asylum seekers (33·0%, 18·3-47·6; I2 =98%) than in other migrant groups (6·6%, 1·8-11·3; I2 =92%). The pooled prevalence of antibiotic-resistant organisms was slightly higher in high-migrant community settings (33·1%, 11·1-55·1; I2 =96%) than in migrants in hospitals (24·3%, 16·1-32·6; I2 =98%). We did not find evidence of high rates of transmission of AMR from migrant to host populations. INTERPRETATION: Migrants are exposed to conditions favouring the emergence of drug resistance during transit and in host countries in Europe. Increased antibiotic resistance among refugees and asylum seekers and in high-migrant community settings (such as refugee camps and detention facilities) highlights the need for improved living conditions, access to health care, and initiatives to facilitate detection of and appropriate high-quality treatment for antibiotic-resistant infections during transit and in host countries. Protocols for the prevention and control of infection and for antibiotic surveillance need to be integrated in all aspects of health care, which should be accessible for all migrant groups, and should target determinants of AMR before, during, and after migration.
