Análisis del uso de audios de mindfulness en la atención y la concentración de estudiantes de formación profesional : Analysis of the use of mindfulness audios in the attention and concentration of vocational training students

Resumen: El objetivo de la investigación fue analizar la influencia de los audios de Mindfulness sobre las capacidades disposicionales de una población adolescente para estar atentos y conscientes de la experiencia del momento presente. El ejercicio se implementó en un centro de Formación Profesional contando con 13 participantes y 18 estudiantes en el grupo de control. Se utilizaron como instrumentos de análisis los cuestionarios validados CAMM, EAP y MAAS-A. Se realizó un análisis de varianza que mostró que quienes recibieron la intervención presentaron pequeñas diferencias en las puntuaciones promedio de ítems concretos para los respectivos cuestionarios trabajados en el proyecto, no encontrándose resultados entre las puntuaciones globales de los cuestionarios entre clases. Palabras Clave: mindfulness, educación profesional, adolescencia.   Abstract The aim of the research was to analyze the impact of the use of exercise audios in mindfulness to verify an increase in the levels of full attention and academic concentration in an adolescent population. The exercise was implemented in a Vocational Training center, with 13 participants and 18 students in the control group. CAMM, EAP and MAAS-A validated questionnaires were used as analysis instruments. An analysis of variance was performed that showed that those who received the intervention presented small differences in the average scores of specific items for the respective questionnaires worked on in the project, with no results being found among the overall scores of the questionnaires between classes. Keywords: mindfulness, professional education, adolescence

Moisturizing body milk as a reservoir of Burkholderia cepacia: outbreak of nosocomial infection in a multidisciplinary intensive care unit

Background: An outbreak of severe nosocomial Burkholderia cepacia infections in patients admitted to intensive care unit (ICU), including investigation of the reservoir, is described. Methods: Over a period of 18 days, isolates of Burkholderia cepacia were recovered from different biological samples from five patients who were admitted to a multidisciplinary 18-bed intensive care unit. Isolation of B. cepacia was associated with bacteraemia in three cases, lower respiratory tract infection in one and urinary tract infection in one. Contact isolation measures were instituted; new samples from the index patients and adjacent patients were collected; and samples of antiseptics, eau de Cologne and moisturizing body milk available in treatment carts at that time were collected and cultured. Results: B. cepacia was isolated from three samples of the moisturizing body milk that had been applied to the patients. Three new hermetically closed units, from three different batches, were sent for culture; two of these were positive as well. All strains recovered from environmental and biological samples were identified as belonging to the same clone by pulsed-field gel electrophoresis. The cream was withdrawn from all hospitalization units and no new cases of B. cepacia infection developed. Conclusion: Moisturizing body milk is a potential source of infection. In severely ill patients, the presence of bacteria in cosmetic products, even within accepted limits, may lead to severe life-threatening infections

Effect of alkyl chain length on the properties of triphenylamine-based hole transport materials and their performance in perovskite solar cells

A new series of diacetylide-triphenylamine (DATPA) derivatives with five different alkyl chains in the para position, MeO, EtO, nPrO, iPrO and BuO, were synthesised, fully characterised and their function as hole-transport materials in perovskite solar cells (PSC) studied. Their thermal, optical and electrochemical properties were investigated along with their molecular packing and charge transport properties to analyse the influence of different alkyl chains in the solar cell parameters. The shorter alkyl chain facilitates more compact packing structures which enhanced the hole mobilities and reduced recombination. This work suggests that the molecule with the methoxy substituent (MeO) exhibits the best semiconductive properties with a power conversion efficiency of up to 5.63%, an open circuit voltage (Voc) of 0.83 V, a photocurrent density (Jsc) of 10.84 mA cm−2 and a fill factor of 62.3% in perovskite solar cells. Upon replacing the methoxy group with longer alkyl chain substituents without changing the energy levels, there is a decrease in the charge mobility as well as PCE (e.g. 3.29% for BuO-DATPA). The alkyl chain length of semiconductive molecules plays an important role in achieving high performance perovskite solar cells

Motores alternativos de combustión interna

Motores alternativos de combustión interna ha sido concebido para proporcionar al lector una visión general de las diferentes partes y subsistemas de los motores alternativos de combustión interna, tanto de aplicación a plantas de tracción motriz para vehículos como a plantas estacionarias para generación de energía eléctrica. Su objetivo básico es cubrir las necesidades bibliográficas para el seguimiento de las asignaturas Ingeniería y Máquinas Térmicas y Ampliación de Motores Térmicos, que se imparten en las escuelas de ingeniería industrial. Asimismo, pretende ofrecer una visión horizontal de las diferentes partes y subsistemas que conforman la máquina alternativa de combustión interna. Los tres primeros capítulos introducen al lector en la problemática de la transformación de energía desde una fuente primaria hasta su forma final en trabajo mecánico en un eje de rotación. En los capítulos siguientes, se analizan los aspectos concretos de la máquina alternativa que nos ocupa, que, dado su funcionamiento pulsante, se estructuran en una fase cerrada, en la que el volumen del cilindro está cerrado al exterior y se desarrollan los procesos para la generación de trabajo (compresión, aportación de calor y expansión), y una fase abierta, en la que el volumen del cilindro está abierto al exterior para realizar los procesos de renovación de la carga; ambas fases se dan tanto en los motores de encendido por compresión (MEC) como en los de encendido por chispa (MEP). Los capítulos finales ofrecen una visión mecánica del mecanismo transformador utilizado en los que se describe su arquitectura mecánica y el detalle de su funcionamiento

Coincideixen els errors més freqüents en dels estudiants de llengua anglesa amb les diferències bàsiques entre la llengua materna i la segona llengua? Anàlisi d'errors com a eina per a millorar la metodologia aplicada a les aules

[cat] El següent treball es fa un anàlisi dels errors més freqüents dels alumnes de 4t de la ESO a l'hora de redactar en llengua anglesa per tal de comprovar si aconsegueixen bons resultats o si mostren massa influència de la llengua materna. Es considera l'existència d'una Gramàtica Universal seguint el model de gramàtica generativista de Chomsky i es té en compte la diferència que mostren diversos autors com White (2000) , Hurtado (1992) o Llopis (2009) entre ensenyament i aprenentatge. Així, després de l'anàlisi s'arriben a les conclusions que els alumnes efectivament estan condicionats per la primera llengua, cosa que demostra que no han adquirit bé la segona llegua. Finalment es fa una reflexió sobre la metodologia empleada a l'aula i es parla de les possibles aplicacions per a la pràctica fent ús de l'error com a eina per a millorar

Prognostic value of severity by various visceral proteins in critically ill patients with SIRS during 7 days of stay

Introduction: Critically ill patients typically develop a catabolic stress state as a result of a systemic inflammatory response (SIRS) that alters clinical-nutritional biomarkers, increasing energy demands and nutritional requirements.Objective: To evaluate the status of albumin, prealbumin and transferrin in critically ill patients and the association between these clinical-nutritional parameters with the severity during a seven day stay in intensive care unit (ICU).Method: Multicenter, prospective, observational and analytical follow-up study. A total of 115 subjects in critical condition were included in this study. Clinical and nutritional parameters and severity were monitored at admission and at the seventh day of the ICU stay.Results: A significant decrease in APACHE II and SOFA (
