Analysis of the mobilization of an unsaturated infinite natural slope due to strength reduction

This work analyses the mobilization of infinite natural slopes that are initially partially saturated. Starting from dry conditions (the water table is assumed to be deep, far from the slope surface), the soil shear strength will decrease when the wetting front advances from the surface. First, the geometry of the failure mechanism that can develop because of such strength reduction is determined. Second, after the mobilization causes the progressive reduction in the soil strength, the slide speed reached the minimum strength is determined, obtaining an indicator of the risk derived from failure.Peer ReviewedPostprint (published version

Estudio exploratorio sobre la cadena de suministros “verde” y el capital humano “verde” en organizaciones del área metropolitana de Monterrey (Exploratory study on the "green" supply chain and "green" human capital in organizations in the metropolitan area of ​​Monterrey)

La cadena de suministros “verde” (CSV) busca implementar un enfoque sostenible a las operaciones de una organización, de manera que esta pueda reducir su impacto ambiental, no obstante, para llevar a cabo una exitosa implementación de la CSV es necesario que el capital humano de la organización entienda y aprecie la cultura “verde”. Existe una falta de estudios relacionados con la CSV en México, por lo que, se busca aportar una perspectiva exploratoria. El presente estudio tiene la siguiente pregunta de investigación: ¿cuáles son los factores que están relacionados con el desempeño organizacional?, de la cual se derivan dos objetivos, por un lado, conocer la percepción que los empleados mexicanos tienen sobre la CSV y el capital humano “verde” (CHV) en sus organizaciones, y, por el otro lado, verificar si existe relación entre la CSV y el CHV con el desempeño de las organizaciones mexicanas. Los resultados arrojan que los empleados consideran que la implementación de estos dos elementos es deficiente, debido a que la mayoría de las preguntas tuvieron una media baja, además, se lograron comprobar, parcialmente, las hipótesis planteadas, en cuanto a la relación de la CSV y Alta dirección con el desempeño organizacional, y las relaciones entre el desempeño ambiental y las variables de CHV e Involucramiento

Conocimientos que tienen las madres sobre signos de alarma de diarrea para llevar un Niño de un mes a 5 anos de edad a consultar la Unidad Comunitaria de Salud Familiar Jucuapa Usulután, y los equipos Comunitarios de Salud Familiar Guajiniquil, Lislique La Unión, La Ermita Morazán año 2019

RESUMEN: Las enfermedades diarreicas constituyen la segunda causa de morbimortalidad en niños menores de 5 años a nivel mundial, debido principalmente a la falta de atención temprana, por el desconocimiento de los padres o factores culturales y económicos que no permiten recibir la atención oportuna. Objetivo: Determinar los conocimientos que tienen las madres sobre signos de alarma de diarrea para llevar a un niño de un mes a 5 años de edad a consultar a la unidad comunitaria de salud familiar Jucuapa y los equipos comunitarios de salud familiar Guajiniquil, Lislique, La Unión, la Ermita Morazán en el año 2019. Metodología: Fue un estudio descriptivo, transversal; se toma como población a 300 madres de niños de un mes a menor de cinco años que consultaron por control infantil o morbilidad a las unidades de salud en estudio y que cumplieron con los criterios de inclusión. Se usó una cedula de entrevista de 31 preguntas que hicieron referencias a las variables de interés. Resultados: El 100% de las madres sabe que es diarrea y signos de gravedad, el 68.3% conoce cuando consultar de inmediato, el 77.67% acude al hospital cuando hay diarrea y mollera hundida. Conclusión: a pesar de que las madres tienen conocimientos de los signos de alarma de diarrea, no todas llegan a consultar de inmediato al niño para que reciba la atención necesaria pues los patrones culturales siguen influyendo en gran parte de la población. ABSTRACT: Diarrheal diseases are the second cause of morbidity and mortality in children under 5 years of age worldwide, mainly due to the lack of early care, the lack of knowledge of parents or cultural and economic factors that do not allow timely care. Objective: To determine the knowledge that mothers have about the warning signs of diarrhea to take a child from one month to 5 years of age to consult the Jucuapa family health community unit and the Guajiniquil, Lislique, La Guajiniquil community family health teams. Unión, the Ermita Morazán in 2019. Methodology: It was a descriptive, cross-sectional study; 300 mothers of children from one month to less than five years old who consulted the health units under study for child control or morbidity and who met the inclusion criteria were taken as a population. An interview form with 31 questions that made references to the variables of interest was used. Results: 100% of the mothers know that it is diarrhea and signs of seriousness, 68.3% know when to consult immediately, 77.67% go to the hospital when there is diarrhea and sunken head. Conclusion: despite the fact that mothers are aware of the warning signs of diarrhea, not all of them come to consult the child immediately so that he receives the necessary care, since cultural patterns continue to influence a large part of the populatio

Partiendo de condiciones secas (se supone que el nivel freático está profundo, lejos de la superficie del talud), la resistencia al cizallamiento del suelo disminuirá cuando el frente de humedecimiento avance desde la superficie. En primer lugar, se determina la geometría del mecanismo de fallo que puede desarrollarse debido a dicha reducción de la resistencia. En segundo lugar, después de que la movilización provoque la reducción progresiva de la resistencia del suelo, se determina la velocidad de deslizamiento alcanzada la resistencia mínima, obteniéndose un indicador del riesgo derivado del fallo

Comparing hysteretic energy and ductility uniform annual failure rate spectra for traditional and a spectral shape-based intensity measure

In this study, with the objective to develop a reliability-based seismic design tool, ductility and dissipated hysteretic energy uniform annual failure rate (UAFR) spectra are obtained and compared using the spectral acceleration at first mode of vibration of the structure Sa(T1) and the well-known spectral shape-based intensity measure INp. Notice that this is the first time in the literature that UAFR spectra are obtained for the advanced spectral shape intensity measure INp. For this aim, 110 simulated ground motions recorded from the soft soil of Mexico City were selected due to their large energy amount demanded to the structures; moreover, four elastoplastic hysteretic behavior models are considered for the dynamic analyses with post-yielding stiffness of 0, 3, 5, and 10%. It is observed that the use of elasto-perfectly plastic models provided similar UAFR spectra in comparison with hysteretic models with different post-yielding stiffness. This conclusion is valid for the two selected intensity measures. In addition, the lateral resistance required to achieve similar structural reliability levels is larger when the INp intensity measure is used, especially for buildings with vibration periods equal or larger than the soil period, in such a way that the traditional use of Sa(T1) could provide structures with less structural reliability levels.Peer ReviewedPostprint (published version

Update on Comprehensive Management of Cholera. Recommendations of the Expert Workshop. Cienfuegos 2014

Cholera is a reemerging disease that was reintroduced into Cuba in late 2012. A provincial workshop attended by 83 professionals from the health institutions in the territory was developed on August 27, 2014 in order to analyse the technical elements for prevention and management of cholera outbreaks and to improve the provincial prevention and control plan for this disease. Group techniques including brainstorming and focus group were applied. Finally, the groups met to present their recommendations and approve the document. Main areas for improvement are related to: keeping an intensive training program, particularly for new professionals and technicians; having safe means for disinfecting and washing contaminated clothes; developing a health promotion and prevention strategy related to “clean hands” and “safe drinking water”; improving the information flow and intra- and inter-sectoral collaboration. It is concluded that the cholera prevention and control plan comprises the technical elements for an appropriate response; however, it can be improved by means of new training and control actions, increased risk perception among health professionals and in the communities, effective control of events and improved networking and inter-sectoral work

Changes in the Viral Distribution Pattern after the Appearance of the Novel Influenza A H1N1 (pH1N1) Virus in Influenza-Like Illness Patients in Peru

Background: We describe the temporal variation in viral agents detected in influenza like illness (ILI) patients before and after the appearance of the ongoing pandemic influenza A (H1N1) (pH1N1) in Peru between 4-January and 13-July 2009. Methods: At the health centers, one oropharyngeal swab was obtained for viral isolation. From epidemiological week (EW) 1 to 18, at the US Naval Medical Research Center Detachment (NMRCD) in Lima, the specimens were inoculated into four cell lines for virus isolation. In addition, from EW 19 to 28, the specimens were also analyzed by real time-polymerase-chainreaction (rRT-PCR). Results: We enrolled 2,872 patients: 1,422 cases before the appearance of the pH1N1 virus, and 1,450 during the pandemic. Non-pH1N1 influenza A virus was the predominant viral strain circulating in Peru through (EW) 18, representing 57.8% of the confirmed cases; however, this predominance shifted to pH1N1 (51.5%) from EW 19–28. During this study period, most of pH1N1 cases were diagnosed in the capital city (Lima) followed by other cities including Cusco and Trujillo. In contrast, novel influenza cases were essentially absent in the tropical rain forest (jungle) cities during our study period. The city of Iquitos (Jungle) had the highest number of influenza B cases and only one pH1N1 case. Conclusions: The viral distribution in Peru changed upon the introduction of the pH1N1 virus compared to previous months. Although influenza A viruses continue to be the predominant viral pathogen, the pH1N1 virus predominated over the other influenza A viruses
