Propuesta de reorganización del transporte público colectivo urbano en Tunja
El presente articulo de reflexion pretende, en primera instancia, es mostrar muy sucintamente la situación actual del sistema de transporte urbano colectivo (TPCU) en la ciudad de Tunja en un marco integral y particular en cada una de las empresas de la ciudad. Así mismo, una vez conocido el diagnóstico correspondiente proponer la creación de un operador único del transporte público colectivo organizado por las empresas existentes, a través de una unión temporal con el propósito o de racionalizar el uso del equipo automotor, buscando una mejor prestación del servicio, que se va a ver reflejada en una major organizacion coordinacion, tecnificacion y operacion integral en el sistema de transporte público para así contribuir a lograr una mayor comodidad, seguridad, disminución de los índices de contaminación ambiental, disminución de la congestión, disminución de los índices de accidentalidad y por ende un mejoramiento de la calidad de vida de sus habitantes, que es lo que en últimas se pretende.La creación tiene que ser liderada por las empresas que actualmente prestan el servicio, pues no se quiere que ocurra lo que ha pasado en algunas ciudades del país, en las que los alcaldes de turno, con intereses económicos oscuros despojen a pequeños transportadores que con esfuerzo y sacrificio han venido contribuyendo en el desarrollo y prestación del servicio de años atrás, para entregárselo a grupos económicos que tienen deseos de invertir, solamente buscando mayores utilidades. Desde luego para evitar enfrentamientos y se respeten los derechos, tiene que contarse con la anuencia del alcalde de turno, para que concertadamente se logre el objetivo propuesto.La metodología empleada fue inicialmente recopilación de información sobre indicadores deTPCU y luego construir una matriz DOFA con el proposito de definer un marco estratégico que permita desarrollar un proceso de integración en la operación del servicio y así buscar la racionalización del servicio y verificar situaciones como: reduccion de la sobreoferta, Disminución de la congestión, Disminución de los tiempos de uso del servicio, optimización de las rutas y frecuencias, mayor certidumbre en horarios y frecuencias, mejora ambiental en la ciudad de aire y ruido, aumento del índice de pasajero- kilómetro I.P.K, y sustitución del parque automotor (Unión Europea, 2003)
Patterns of alcohol consumption and use of health services in spanish university students: UniHcos Project
The aim of the study was to examine the association of alcohol consumption patterns (hazardous alcohol use and binge drinking) and the use of emergency services and primary care consultations in university students. An observational, descriptive, cross-sectional study was conducted at eleven Spanish universities collaborating within the uniHcos Project. University students completed an online questionnaire that assessed hazardous alcohol use and binge drinking using the AUDIT questionnaire and evaluated the use of emergency services and primary care. A descriptive analysis of the data was performed, as well as the chi-squared test and Student's t-test and nonconditional logistic regression models to examine this association. Results: There were 10,167 participants who completed the questionnaire. The prevalence of hazardous alcohol use was 16.9% (95% CI: 16.2?17.6), while the prevalence of binge drinking was 48.8% (95% CI: 47.9?49.8). There were significant differences in the use of emergency services in those surveyed with hazardous alcohol use (p < 0.001) or binge drinking pattern (p < 0.001). However, no significant differences were observed in terms of attendance during primary care visits in individuals with hazardous alcohol use (p = 0.367) or binge drinking pattern (p = 0.755). The current study shows the association between university students with a pattern of hazardous alcohol use or binge drinking and greater use of emergency services. However, no significant association was observed between the said consumption patterns and the use of primary care services
Role of age and comorbidities in mortality of patients with infective endocarditis
[Purpose]: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality.
[Methods]: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.The area under the receiver-operating characteristic (AUROC) curve was calculated to quantify the diagnostic accuracy of the CCI to predict mortality risk.
[Results]: A total of 3120 patients with IE (1327 < 65 years;1291 65-80 years;502 ≥ 80 years) were enrolled.Fever and heart failure were the most common presentations of IE, with no differences among age groups.Patients ≥80 years who underwent surgery were significantly lower compared with other age groups (14.3%,65 years; 20.5%,65-79 years; 31.3%,≥80 years). In-hospital mortality was lower in the <65-year group (20.3%,<65 years;30.1%,65-79 years;34.7%,≥80 years;p < 0.001) as well as 1-year mortality (3.2%, <65 years; 5.5%, 65-80 years;7.6%,≥80 years; p = 0.003).Independent predictors of mortality were age ≥ 80 years (hazard ratio [HR]:2.78;95% confidence interval [CI]:2.32–3.34), CCI ≥ 3 (HR:1.62; 95% CI:1.39–1.88),and non-performed surgery (HR:1.64;95% CI:11.16–1.58).When the three age groups were compared,the AUROC curve for CCI was significantly larger for patients aged <65 years(p < 0.001) for both in-hospital and 1-year mortality.
[Conclusion]: There were no differences in the clinical presentation of IE between the groups. Age ≥ 80 years, high comorbidity (measured by CCI),and non-performance of surgery were independent predictors of mortality in patients with IE.CCI could help to identify those patients with IE and surgical indication who present a lower risk of in-hospital and 1-year mortality after surgery, especially in the <65-year group
Post-Franco Theatre
In the multiple realms and layers that comprise the contemporary Spanish theatrical landscape, “crisis” would seem to be the word that most often lingers in the air, as though it were a common mantra, ready to roll off the tongue of so many theatre professionals with such enormous ease, and even enthusiasm, that one is prompted to wonder whether it might indeed be a miracle that the contemporary technological revolution – coupled with perpetual quandaries concerning public and private funding for the arts – had not by now brought an end to the evolution of the oldest of live arts, or, at the very least, an end to drama as we know it
Dealloying of Cobalt from CuCo Nanoparticles under Syngas Exposure
International audienceThe structure and composition of core−shell CuCo nanoparticles were found to change as a result of cleaning pretreatments and when exposed to syngas (CO + H 2) at atmospheric pressure. In situ X-ray absorption and photoelectron spectroscopies revealed the oxidation state of the particles as well as the presence of adsorbates under syngas. Transmission electron microscopy was used for ex situ analysis of the shape, elemental composition, and structure after reaction. The original core−shell structure was found to change to a hollow CuCo alloy after pretreatment by oxidation in pure O 2 and reduction in pure H 2. After 30 min of exposure to syngas, a significant fraction (5%) of the particles was strongly depleted in cobalt giving copper-rich nanoparticles. This fraction increased with duration of syngas exposure, a phenomenon that did not occur under pure CO or pure H 2. This study suggests that Co and Cu can each individually contribute to syngas conversion with CuCo catalysts
