Lessons learned from the field analysis of PV installations in the Saharawi refugee camps after 10 years of operation

Energy access at refugee camps is one of the main challenges to address in humanitarian response actions, especially on long-term situations. The lack of access to electricity depends, among other factors, on the local natural resources and available technologies. In this sense, solar photovoltaic is one of the most appropriate technologies, especially now with the decrease of the photovoltaic costs. But long-term performance, reliability and social acceptance must be ensured to facilitate the introduction of the technology and its rapid widespread in these humanitarian context. This work presents the results of a field study conducted at the Saharawi refugee camps, inspecting the photovoltaic systems installed in the health institutions after 10 years of use. Results show how despite the good initial system design and high quality of the PV components, the lack of training on operation and maintenance of the PV installations have led to a dramatic reduction of the lifetime of the systems. Strong training programs on basic photovoltaic concepts and operation and maintenance of systems are required to solve this problem and guarantee the long-term functioning of the installations.The authors acknowledge funding from the ‘Agencia Andaluza de Cooperación Internacional para el Desarrollo’ (AACID), project number 2014DEC008

Use of crowdfunding in Chile: an exploratory approach

The FinTech industry includes crowdfunding companies, which consist of collaborative financing platforms. The potential use of crowdfunding among Chilean undergraduate students is empirically analyzed. An ordered probit model is used to test the determinants of the probability that a student will use a crowdfunding platform in the future. Also, a qualitative analysis containing arguments by which students would or would not use crowdfunding in the future is presented. The results indicate that trust in financial institutions and prior crowdfunding knowledge have a positive and significant effect on the probability of using these platforms. This paper constitutes one of the first to explore the growing crowdfunding market in Chile from the demand perspective

Efectos de un plan de entrenamiento de ocho semanas en la capacidad de autovalencia en adultos mayores

Tesis (Profesor de Educación Física para la Enseñanza Básica, Licenciado en Educación)Tanto en Chile como en el mundo entero la población de adultos mayores va aumentando de manera exponencial y el paso del tiempo trae consigo de manera indeclinable e indefectible la aparición de ciertas enfermedades por el respectivo deterioro generalizado en las funciones orgánicas; además existen ciertos factores que determinan el ritmo de envejecimiento como los de carácter genético, metabólico, hormonal, ambiental y por supuesto el estilo de vida que lleva la persona. Un estilo de vida sedentario repercute de manera negativa en el adulto mayor, acelerando su proceso de envejecimiento y trascendiendo invariablemente en su nivel de autovalencia, es ahí donde yace el foco principal de este estudio, ya que se pretende determinar los efectos de un plan de entrenamiento de ocho semanas de duración en la capacidad de auto valencia en adultos mayores, mediante la aplicación de los exámenes de medicina preventiva del adulto mayor (EMPAM); teniendo como base que el ejercicio físico constituye el medio más seguro para mantener la autonomía, asegurar las capacidades motrices y cognitivas, además de potenciar la sociabilidad y educar sobre el uso del tiempo libre, evitando el sedentarism

Modeling GHG emissions, N and C dynamics in Spanish agricultural soils.

To date, only few initiatives have been carried out in Spain in order to use mathematical models (e.g. DNDC, DayCent, FASSET y SIMSNIC) to estimate nitrogen (N) and carbon (C) dynamics as well as greenhouse gases (GHG) in Spanish agrosystems. Modeling at this level may allow to gain insight on both the complex relationships between biological and physicochemical processes, controlling the processes leading to GHG production and consumption in soils (e.g. nitrification, denitrification, decomposing, etc.), and the interactions between C and N cycles within the different components of the continuum plant-soil-environment. Additionally, these models can simulate the processes behind production, consumition and transport of GHG (e.g. nitrous oxide, N2O, and carbon dioxide, CO2) in the short and medium term and at different scales. Other sources of potential pollution from soils can be identified and quantified using these process-based models (e.g. NO3 y NH3)

Aspecto socio-cultural de la transferencia de tecnología de energías renovables en la comunidad terapéutica de Tekové-Rogá

La experiencia realizada en la Comunidad Terapéutica de Tekové-Rogá se encuadra en el Proyecto de Ejecución Práctica y Educación en Energías Renovables y Agua Potable, su implementación depende del Ministerio de Desarrollo Social de la Nación, la Secretaría Nacional de Niñez, Adolescencia y Familia (SENNAF) y la Universidad Tecnológica Nacional (UTN). El objetivo del trabajo es analizar el impacto social que este tipo de experiencias genera, para lograrlo el abordaje metodológico utilizado fue cuanti-cualitativo, en tanto se recolectaron datos estadísticos de la institución que permitieron relevar información sobre su plantel profesional, y cualitativa en tanto indagamos las percepciones que los actores de la institución tienen en relación al proyecto de ejecución en energías renovables. Las conclusiones principales dan cuenta del impacto social en tres ejes diferentes: el impacto a nivel institucional de la comunidad terapéutica, el impacto a nivel socio-cultural y el impacto a nivel académico.The experience realized in Tekové-Rogá's Therapeutic Community is fitted in the Project of Practical Execution and Education in Renewable Energies and Water, his implementation depends on the Department of Social Development of the Nation, the National Secretariat of Childhood, Adolescence and Family (SENNAF) and the Technological National University (UTN). The work analyze the social impact that this type of experiences. The principal conclusions are in three different axes: the first one is related to the impact to institutional level of the therapeutic community, the second one links itself with the impact to socio-cultural level, which can be indirect ó directly. Finally the third axis in which the social impact is identified is to academic level, in which they receive relevancy the innovation in the development of new devices, the role of the university and the impact in the professional identities involved in the project.Asociación Argentina de Energías Renovables y Medio Ambiente (ASADES

Evaluation of Adipose Tissue Zinc-Alpha 2-Glycoprotein Gene Expression and Its Relationship with Metabolic Status and Bariatric Surgery Outcomes in Patients with Class III Obesity

Zinc-α2 glycoprotein (ZAG) is an adipokine involved in adipocyte metabolism with potential implications in the pathogenesis of metabolic disorders. Our aim was to evaluate the relationship between visceral (VAT) and subcutaneous adipose tissue (SAT) ZAG expression and metabolic parameters in patients with class III obesity, along with the impact of basal ZAG expression on short- and medium-term outcomes related to bariatric surgery. 41 patients with class III obesity who underwent bariatric surgery were included in this study. ZAG gene expression was quantified in SAT and VAT. Patients were classified into two groups according to SAT and VAT ZAG percentile. Anthropometric and biochemical variables were obtained before and 15 days, 45 days, and 1 year after surgery. The lower basal SAT ZAG expression percentile was associated with higher weight and waist circumference, while the lower basal VAT ZAG expression percentile was associated with higher weight, waist circumference, insulin, insulin resistance, and the presence of metabolic syndrome. Basal SAT ZAG expression was inversely related to weight loss at 45 days after surgery, whereas no associations were found between basal VAT ZAG expression and weight loss after surgery. Additionally, a negative association was observed between basal SAT and VAT ZAG expression and the decrease of gamma-glutamyl transferase after bariatric surgery. Therefore, lower SAT and VAT ZAG expression levels were associated with an adverse metabolic profile. However, this fact did not seem to confer worse bariatric surgery-related outcomes. Further research is needed to assess the clinical significance of the role of ZAG expression levels in the dynamics of hepatic enzymes after bariatric surgeryThis study has been co-funded by FEDER funds (“A way to make Europe”).
