ENERGÍA ALTERNATIVA: PRODUCCIÓN DE ENERGÍA EÓLICA, OPCIÓN DE DESARROLLO EN LA VENTA, JUCHITÁN, OAXACA, MÉXICO

This study was carried out in the ejido of La Venta, Juchitán de Zaragoza, Oaxaca, México, in order to document a case of success related to the higher number of wind energy producers. La Venta is producing an important amount of megawatts through the transformation of wind energy; however, an option of development as such does not exist because payment for land rental is not proportional to the energy produced, in addition to the unequal distribution of contracts negotiated with the companies, adding that the lands are ejido property, and consequently, not all inhabitants are benefitted, the payments are different depending on the company that rents from them and the type of installation that they carry out in their properties. The main objective of this study was to analyze the social impact that there is in La Venta, Juchitán de Zaragoza, Oaxaca, in face of land rental for the generation of wind energy. The transnational companies purchase the energy obtained and the ejido only rents the lands, the electricity fees in the ejido continue being the same they paid before the installation of wind parks, when they should decrease. Obtaining income from land rental has modified the social panorama of the population.La presente investigación se realizó en el ejido de La Venta, Juchitán de Zaragoza, Oaxaca, México, para documentar un caso de éxito relacionado con la mayor cantidad de productores de energía eólica. La Venta, está produciendo una cantidad importante de megawatts a través de transformar la energía eólica, sin embargo, una opción de desarrollo como tal no existe, debido a que el pago por la renta de las tierras no es proporcional con la energía que se produce, además de la distribución desigual de los contratos pactados con las empresas, agregando que las tierras son de propiedad ejidal, y en consecuencia, no todos los habitantes son beneficiados, los pagos son diferentes dependiendo de la empresa que les arrende y el tipo de instalación que realicen en sus propiedades. El objetivo principal de la investigación fue analizar el impacto social que existe en La Venta, Juchitán de Zaragoza, Oaxaca, ante el arrendamiento de tierras para la generación de energía eléctrica. Las transnacionales compran la energía obtenida y el ejido solo renta las tierras, las tarifas de electricidad en el ejido siguen siendo las mismas que pagaban antes de la instalación de los parques eólicos, cuando deberían disminuir. La obtención de ingreso por arrendar las tierras, ha modificado el panorama social de la población

Rheological Behaviour of an Insoluble Lemon Fibre as Affected by Stirring, Temperature, Time and Storage

The final publication is available at link.springer.comIn this work, the effect the preparation method (two different stirring systems at two temperatures and times), fibre concentration (between 2% and 3%), temperature (between 10 °C and 50 °C) and storage time (between 24 h and 50 days at 5 °C) had on the flow properties of a suspension of dietary lemon fibre prepared with a 45° Brix sucrose solution were evaluated. This information will be helpful in order to discover the best possibilities of using fibre to increase the viscosity of certain kinds of products, depending on the processing, storage and consumption conditions. The obtained results indicate that all the aspects which contribute to increase component solubilisation and the interaction of the insoluble fraction with the aqueous phase when preparing the suspension, such as a decrease in particle size, a rise in temperature or a longer homogenization time, entail a higher apparent viscosity. Moreover, favoring the solubilisation in the preparation process leads to a more stable rheological behaviour of the suspension during storage. As expected, the apparent viscosity of suspensions was dependent on the shear rate, concentration and temperature. A thixotropic behaviour of fibre suspension was only observed at a very low shear rate (5 s -1). © 2010 Springer Science + Business Media, LLC.Córdoba Sequeira, A.; Camacho Vidal, MM.; Martínez Navarrete, N.

The Antares Collaboration : Contributions to the 34th International Cosmic Ray Conference (ICRC 2015, The Hague)

The ANTARES detector, completed in 2008, is the largest neutrino telescope in the Northern hemisphere. Located at a depth of 2.5 km in the Mediterranean Sea, 40 km off the Toulon shore, its main goal is the search for astrophysical high energy neutrinos. In this paper we collect the 21 contributions of the ANTARES collaboration to the 34th International Cosmic Ray Conference (ICRC 2015). The scientific output is very rich and the contributions included in these proceedings cover the main physics results, ranging from steady point sources, diffuse searches, multi-messenger analyses to exotic physics

All-sky Search for High-Energy Neutrinos from Gravitational Wave Event GW170104 with the ANTARES Neutrino Telescope

Advanced LIGO detected a significant gravitational wave signal (GW170104) originating from the coalescence of two black holes during the second observation run on January 4$^{\textrm{th}}$, 2017. An all-sky high-energy neutrino follow-up search has been made using data from the ANTARES neutrino telescope, including both upgoing and downgoing events in two separate analyses. No neutrino candidates were found within $\pm500$ s around the GW event time nor any time clustering of events over an extended time window of $\pm3$ months. The non-detection is used to constrain isotropic-equivalent high-energy neutrino emission from GW170104 to less than $\sim4\times 10^{54}$ erg for a $E^{-2}$ spectrum

All-sky Search for High-Energy Neutrinos from Gravitational Wave Event GW170104 with the ANTARES Neutrino Telescope

[EN] Advanced LIGO detected a significant gravitational wave signal (GW170104) originating from the coalescence of two black holes during the second observation run on January 4th, 2017. Anall-sky high-energy neutrino follow-up search has been made using data from the Antares neutrino telescope, including both upgoing and downgoing events in two separate analyses. No neutrino candidates were found within +/- 500 s around the GW event time nor any time clustering of events over an extended time window of +/- 3 months. The non-detection is used to constrain isotropic-equivalent high-energy neutrino emission from GW170104 to less than similar to 1.2 x 10(55) erg for a E-2 spectrum. This constraint is valid in the energy range corresponding to the 5-95% quantiles of the neutrino flux [3.2 TeV; 3.6 PeV], if the GW emitter was below the Antares horizon at the alert time.The ANTARES Collaboration is grateful to the LIGO Scientific Collaboration and the Virgo Collaboration for the setting up of an impressive follow-up observation program, and for sharing invaluable scientific information for the benefit of the emerging multi-messenger astronomy.
