The history and creation of the Agenda 2030: Designing the sustainable development goals.

This article analyzes and studies the history and background of the Sustainable Development Goals (SDGs). Firstly, a historical journey has been made to understand the evolution and development of education up to the arrival of the 2030 Agenda for Sustainable Development action plan. In this way, a timeline was presented that reflects the path taken by the United Nations and the international community to arrive at To reach this new international framework. In this line, the post-2015 agenda, conferences, summits and international decades have been examined, as they were decisive events for the adoption of the SDGs. A official UN documents and programmes were analysed, demonstrating the enormous volume of documentation that has been published on the subject. There is no better way to understand the international interest generated by the proposed topic than to read the "Preamble1" of Resolution A/RES/70/1, 25September 2015, Transforming our world: the United Nations 2030 Agenda for Sustainable Development. In this document you can find the new proposal for a better and higher quality future for all people on the planet.pre-print281 K

Evaluación del efecto del bypass en recuperadores de calor sobre el consumo energético de ventilación. Caso de estudio

La preocupación por la conservación del medioambiente es cada vez mayor debido al elevado impacto ambiental producido por el consumo de las fuentes de energía convencionales. Además, existen unas exigencias por la normativa vigente, de la necesidad de disponer de un buen confort térmico en interiores. Todo esto ha llevado a la búsqueda de la eficiencia energética en edificios, es decir, es primordial el uso de sistemas que permitan reducir el uso de energía y sus costes derivados, sin perder con ello calidad del ambiente esperada. El presente trabajo se enmarca dentro del ahorro energético en edificios, consistiendo en el estudio de una de las estrategias más aplicadas para mejorar la eficiencia en edificios, como es la recuperación de calor, que busca minimizar la energía empleada en sistemas de ventilación. Existen distintas estrategias de reducción de la demanda térmica de ventilación y una de ellas son los recuperadores de calor, donde los más usados suelen ser los recuperadores de placas, rotativos y los de dos baterías con bomba (en inglés, coil heat recovery runaround loop). Pero estos sistemas introducen una importante pérdida de carga en la instalación, lo que genera un aumento del consumo eléctrico asociado a los ventiladores. Por otro lado, la mayor parte de los recuperadores instalados hasta hoy en día no permiten realizar el by-pass del sistema en los períodos donde no está funcionando. El trabajo estudia el efecto que tendría dicho by-pass y así poder justificar de forma cuantitativa la instalación de sistemas que permitan evitar el paso del aire de renovación a través del intercambiador cuando este no permita alcanzar ahorros térmicos relevantes. Y con estos resultados también se podrá comparar los ahorros térmicos frente a los consumos eléctricos adicionales introducidos por el ventilador, determinando las consignas óptimas de funcionamiento del sistema.Departamento de Ingeniería Energética y FluidomecánicaMáster en Ingeniería Industria

Perfil de resistencia antimicrobiana en pacientes con infección urinaria del servicio de emergencia adulto del Hospital San Jose de Callao del 2010 – 2017

Las infecciones del tracto urinario (IU) son una de las enfermedades infecciosas más frecuentes en los entornos hospitalarios y comunitarios que son una causa considerable de morbilidad y mortalidad. Las infecciones urinarias se presentan en todos los grupos de edad, pero algunos grupos como los recién nacidos, las mujeres embarazadas o los pacientes de edad avanzada, pacientes que presentan algún grado de inmunosupresión o comorbilidad: diabetes mellitus, pacientes reumatológicos, oncológicos, son lo más vulnerable

Vascular Endothelial Growth Factor (VEGF) Prevents the Downregulation of the Cholinergic Phenotype in Axotomized Motoneurons of the Adult Rat

Vascular endothelial growth factor (VEGF) was initially characterized by its activity on the vascular system. However, there is growing evidence indicating that VEGF also acts as a neuroprotective factor, and that its administration to neurons suffering from trauma or disease is able to rescue them from cell death. We questioned whether VEGF could also maintain damaged neurons in a neurotransmissive mode by evaluating the synthesis of their neurotransmitter, and whether its action would be direct or through its well-known angiogenic activity. Adult rat extraocular motoneurons were chosen as the experimental model. Lesion was performed by monocular enucleation and immediately a gelatine sponge soaked in VEGF was implanted intraorbitally. After 7 days, abducens, trochlear, and oculomotor nuclei were examined by immunohistochemistry against choline acetyltransferase (ChAT), the biosynthetic enzyme of the motoneuronal neurotransmitter acetylcholine. Lesioned motoneurons exhibited a noticeable ChAT downregulation which was prevented by VEGF administration. To explore whether this action was mediated via an increase in blood vessels or in their permeability, we performed immunohistochemistry against laminin, glucose transporter-1 and the plasmatic protein albumin. The quantification of the immunolabeling intensity against these three proteins showed no significant differences between VEGF-treated, axotomized and control animals. Therefore, the present data indicate that VEGF is able to sustain the cholinergic phenotype in damaged motoneurons, which is a first step for adequate neuromuscular neurotransmission, and that this action seems to be mediated directly on neurons since no sign of angiogenic activity was evident. These data reinforces the therapeutical potential of VEGF in motoneuronal diseases.España, MINECO and FEDER BFU2015-64515-PJunta de Andalucía and FEDER : P10-CVI605

Complete chemical hydrolysis of cellulose into fermentable sugars via ionic liquids and antisolvent pretreatments

This work describes a relatively simple methodology for efficiently deconstructing cellulose into monomeric glucose, which is more easily transformed into a variety of platform molecules for the production of chemicals and fuels. The approach undertaken here first involves the dissolution of cellulose in an ionic liquid (IL), followed by a second reconstruction step aided by an antisolvent. The regenerated cellulose exhibited strong structural and morphological changes, as revealed by X-ray diffraction (XRD) and scanning electron microscopy (SEM) analyses. These changes dramatically affect the hydrolytic reactivity of the cellulose with dilute mineral acids. As a consequence, the glucose yield obtained from the deconstructed-reconstructed cellulose was substantially higher than that achieved via hydrolysis of the starting cellulose. Factors that affect the hydrolysis reaction include the type of cellulose substrate, the type of IL used in the pretreatment and the type of acid used in the hydrolysis step. The best results were obtained by treating the cellulose with IL and using phosphotungstic acid (0.067 mol/L) as a catalyst at 413 K. Under these conditions, the conversion of cellulose was almost complete (> 99 %), with a glucose yield of 87 % after only 5 h of reaction.Comunidad de Madrid (Spain) S2009/ENE-1743CSIC (Spain) 201180E038Peer reviewe

Laboratory 3.0: manufacturing technologies laboratory virtualization with a student-centred methodology

This paper presents a blended-learning strategy for improving the teaching method applied in the laboratory subject Manufacturing Technologies. The teaching method has been changed from a predominantly teacher-centred to an active learning system with a student-centred focus and e-learning activities. In face-to-face classes, a game-based learning platform has been used. This methodology ensured engaging classes at the same time that provided a useful live feedback for students and teachers. The virtualization of the laboratory was achieved by two different e-learning activities, self-assessment tasks and video clips. These e-learning tools have been used not only to improve the students’ learning but also to enhance their motivation. The results from academic outputs show a significant improvement after the new blended learning method is applied. Moreover, a student satisfaction survey shows the positive impact of the methodology on the students’ engagement and motivationPeer Reviewe
