Educação artística para o desenvolvimento de bem-estar subjetivo: A experiência chilena

Chile se encuentra en una transformación profunda de su sistema educativo, revisando y resignificando el concepto de calidad de la educación, cuestionando la competitividad como motor de ésta y preguntándose por el rol de la diversidad y la equidad en la formación integral de los estudiantes. El sistema educacional presenta altos índices de desigualdad, reflejo de una sociedad inequitativa. La escuela contribuye hoy a mantener las diferencias sociales, impacta negativamente en la percepción del bienestar subjetivo y las expectativas de desarrollo de muchos estudiantes. Los programas públicos de educación artística ofrecen una oportunidad estratégica al desarrollo de habilidades diversas para una educación integralChile is undergoing a process of deep transformation to its educational system, revising and reframing the concept of quality of education, questioning competitiveness as its driver and wondering about the role of diversity and equity in comprehensive education of students. The educational system shows high levels of inequality, as reflection of an inequitable society. Today, schools contribute to preserve social differences, negatively impacting on the perception of subjective well-being and on the expectations of development of many students.

Kinematic study of planetary nebulae in NGC 6822

By measuring precise radial velocities of planetary nebulae (which belong to the intermediate age population), H II regions, and A-type supergiant stars (which are members of the young population) in NGC 6822, we aim to determine if both types of population share the kinematics of the disk of H I found in this galaxy. Spectroscopic data for four planetary nebulae were obtained with the high spectral resolution spectrograph Magellan Inamori Kyocera Echelle (MIKE) on the Magellan telescope at Las Campanas Observatory. Data for other three PNe and one H II region were obtained from the SPM Catalog of Extragalactic Planetary Nebulae which employed the Manchester Echelle Spectrometer attached to the 2.1m telescope at the Observatorio Astron\'omico Nacional, M\'exico. In the wavelength calibrated spectra, the heliocentric radial velocities were measured with a precision better than 5-6 km s$^{-1}$. Data for three additional H II regions and a couple of A-type supergiant stars were collected from the literature. The heliocentric radial velocities of the different objects were compared to the velocities of the H i disk at the same position. From the analysis of radial velocities it is found that H II regions and A-type supergiants do share the kinematics of the H I disk at the same position, as expected for these young objects. On the contrary, planetary nebula velocities differ significantly from that of the H I at the same position. The kinematics of planetary nebulae is independent from the young population kinematics and it is closer to the behavior shown by carbon stars, which are intermediate-age members of the stellar spheroid existing in this galaxy. Our results are confirming that there are at least two very different kinematical systems in NGC 6822

Implementación de control diversor de carga automático para microcentral hidroeléctrica

Proyecto de Graduación (Licenciatura en Ingeniería Electrónica) Instituto Tecnológico de Costa Rica, 2018The present graduation project report was developed in the SME Interdinámica Energía, a Costa Rican company dedicated to the development of projects with renewable energies. The aim of the project was to implement an automatic load diversifier controller for the control of battery charge states in small hydroelectric plants. The installations of hydroelectric power plants without connection to the electric network require the use of a battery bank, as an energy storage element, and a charge controller. These controllers are safety systems for the turbine, as it keeps the plant operating under nominal conditions, maximizing system performance in general and extending the life of the equipment. The charge controllers available on the market are expensive and often have difficulty adapting to the characteristics of the installation. The project consists of the implementation of an automatic load diversifier controller, capable of varying up to 2kW of power for battery banks with nominal voltage of 12V and 24V

Motivación hacia programas de ejercicio, deporte y actividad física de los empleados de UNE Telefónica de Pereira 2012

Se describieron los factores motivacionales hacia actividades recreodeportivas de los empleados de UNE Telefónica de Pereira durante el año 2012, de orden físico, social, económico y ambiental. La población de ambos géneros oscilaba entre los 18 y 60 años, pertenecían en su mayoría al estrato 3 con un nivel académico de secundaria y pregrado; desarrollaban actividades laborales de campo, oficina o mixtas. De las 431 personas, se obtuvo una muestra de 203 a través de un muestreo aleatorio simple. El instrumento utilizado se basó en el cuestionario internacional de actividad física Agita Sao Paulo (IPAQ) y fue validado al contexto local a través de una prueba piloto. El 49% y el 63% de los encuestados conocían respectivamente la existencia de los escenarios y programas recreodeportivos de la empresa. Un 51% de las personas manifestaron hacer o haber hecho ejercicio y querer seguir una disciplina, solo un 2,5% dijeron no considerar la práctica en actividades recreodeportivas. Como se ha podido determinar en otros estudios, el cuidado de la salud fue de los motivos principales para la práctica en actividades recreodeportivas, con un 80%, seguido de una buena forma física con un 70%. Sobre las razones de abandono o no participación, la mayor parte manifestaron no tener tiempo o disciplina suficiente. Para el 60% de los empleados, la empresa debería ofertar otros programas y escenarios recreodeportivos, especialmente más programas familiares, y conseguir canchas deportivas múltiples a través de convenios.Motivational factors were described to recreation-sports activities of employees of UNE Telefonica from Pereira in 2012.

Virtual Screening of Plant Volatile Compounds Reveals a High Affinity of Hylamorpha elegans (Coleoptera: Scarabaeidae) Odorant-Binding Proteins for Sesquiterpenes From Its Native Host

Indexación: Web of ScienceHylamorpha elegans (Burmeister) is a native Chilean scarab beetle considered to be a relevant agricultural pest to pasture and cereal and small fruit crops. Because of their cryptic habits, control with conventional methods is difficult; therefore, alternative and environmentally friendly control strategies are highly desirable. The study of proteins that participate in the recognition of odorants, such as odorant-binding proteins (OBPs), offers interesting opportunities to identify new compounds with the potential to modify pest behavior and computational screening of compounds, which is commonly used in drug discovery, may help to accelerate the discovery of new semiochemicals. Here, we report the discovery of four OBPs in H. elegans as well as six new volatiles released by its native host Nothofagus obliqua (Mirbel). Molecular docking performed between OBPs and new and previously reported volatiles from N. obliqua revealed the best binding energy values for sesquiterpenic compounds. Despite remarkable divergence at the amino acid level, three of the four OBPs evaluated exhibited the best interaction energy for the same ligands. Molecular dynamics investigation reinforced the importance of sesquiterpenes, showing that hydrophobic residues of the OBPs interacted most frequently with the tested ligands, and binding free energy calculations demonstrated van der Waals and hydrophobic interactions to be the most important. Altogether, the results suggest that sesquiterpenes are interesting candidates for in vitro and in vivo assays to assess their potential application in pest management strategies.http://jinsectscience.oxfordjournals.org/content/16/1/3

Biogas home-production assessment using a selective sample of organic vegetable waste. A preliminary study

Biogas generation plants using organic waste are a daily reality that can be observed in different areas of waste disposal that exist in many cities of the world. In fact, the generation of biogas through anaerobic bio-digestion of urban wastes has a high impact in terms of energy use and reduced environmental liabilities. The present study focuses on the assessment of biogas production for domestic consumption; several biodigesters were tested in order to evaluate the biogas production under standard pressure and temperature. The test estimates volume of biogas being produced, substrate pH and substrate concentration, using different types of catalysts. A test bed was designed for testing three digesters (A, B and C) within recycled bottles of polyethylene terephthalate (PET), whose maximum volume is ~0.6 liters. A 60g organic substrate compound was placed in each bottle. The organic compound consisted of peeling residues of potatoes, cabbage and carrots. Experimental characterization of the mixture allowed to observe the production of biogas for domestic use, system temperature, pH levels achieved, mass and substrate concentration, as well as concentration and volume of the catalyst. Further studies, with a larger sample and monitoring the container pressure are recommended in order to establish a more precise relation among the whole set of experimental parameters
