description Publicationkeyboard_double_arrow_right Article 2011 ColombiaPublisher:Universidad de Medellín Authors: Anaya Acevedo, Jesús Adolfo; Chuvieco Salinero, Emilio; Palacios-Orueta, Alicia;La quema de biomasa es una fuente importante de gases efecto invernadero en países en vías de desarrollo. En Colombia, el cambio de uso del suelo, la silvicultura y el sector agropecuario superan el 50% de las emisiones totales de efecto invernadero.El fuego se utiliza con frecuencia como un mecanismo para cambiar el uso del suelo. Los Llanos orientales y la Amazonía colombiana están sometidos todos los años a la quema de biomasa, especialmente entre enero y marzo. Los estudios en la distribución espacial y temporal de las emisiones son importantes de cara a los informes en el ámbito nacional. Este artículo de revisión describe el método para hacer estas estimaciones utilizando teledetección y algunos de los resultados disponibles para Colombia.ABSTRACTBiomass burning is a major source of greenhouse gas emissions in developing countries. In Colombia, land use change, forestry, and agriculture are responsible for more than 50% of the total greenhouse gas emissions. Fire is commonly used as a mechanism for land use change. In Colombia the Llanos Orientales and the Amazonia are subject to biomass burning every year during the dry season, specially from January to March. Studies of the spatial and temporal distribution of emissions are required for emissions report at a national level. The goal of this state of the art article is to describe a method to estimate emissions with a remote sensing approach and to present some of the variables already measured in Colombia.Key words: emissions, remote sensing, biomass, burned area.

Mientras la región se vincula cada vez más con la sociedad nacional de Honduras, varios procesos socioeconómicos están transformando las comunidadesde la reserva. Esta investigación se enfoca en tres comunidades ubicadas a lo largo del límite oriental de la biosfera. Pocas casas todavía están orientadas totalmente en la subsistencia. La mayoría combina la subsistencia con varias otras actividades que rinden el dinero. Este estudio demuestra que la sostenibilidad de la agricultura itinerante no es una cuestión solamente de sus límites ambientales, sino su valor en comparación a otras actividades económicas que existen ahora en la Mosquitia hondureña, así como en otras regiones fronteras de la América Central.Palabras claves: Mosquitia hondureña, río Plátano, sostenibilidad, agricultura itinerante, cambio socioeconómico.AbstractThis article examines the process in which shifting cultivation is becoming marginalized in the Río Plátano Biosphere of the Honduran Mosquitia. As the region becomes increasingly tied to the national society of Honduras, various socioeconomic processes are transforming communities in the reserve.This investigation focuses on three communities located along the eastern boundary of the biosphere.Few houses are still oriented solely on subsistence. The majority combine subsistence with various other money-making activities. This research demonstrates that the sustainability of shifting cultivation is not solely a question of its environmental limits, but also its value in comparison to other economic activities that are now present in the Honduran Mosquitia, as well as in other frontier regions of Central America.Keywords: Honduran Mosquitia, Río Plátano, sustainability, shifting cultivation, socioeconomic change

El argumento principal sugiere que la descripción de este espacio crucial para la modernidad, dada la retórica de los escritores de viajes y ficción, transforma el área insular para concebir formas alternativas del proyecto de construcción nacional en América Latina. Como resultado de las empresas coloniales, excursiones científicas, crónicas periodísticas o expediciones, la escritura de viaje de las Galápagos condiciona la formación del estado y su imaginario nacional. Esto ocurre por el capital simbólico que posee archipiélago y por el deseo de los intelectuales latinoamericanos de pertenecer a un territorio cosmopolita. El espacio insular funciona como un significante vacío donde los viajeros pueden comunicar su propio significado al narrar las experiencias de sus viajes. Este fenómeno crea una división conceptual y política entre la identidad de las islas y la nación ecuatoriana. Dichas ambigüedades narrativas crearon una ruptura que condujo a variaciones fundamentales en la forma en que los habitantes locales y entidades extranjeras interpretan las Galápagos hoy en día, ya que su literatura refleja una tensión particular de cara a las tendencias migratorias en las islas, así como los intereses globales que prevalecen en la apropiación del espacio. This book, written in Spanish, takes a literary and cultural studies model to explain the textual representation of the Galápagos Islands since their discovery until present day. The main argument suggests that the depiction of this crucial space for modernity in Western thought, given the rhetoric of travel and fiction writers, transforms the insular area with the intention of conceiving disparate forms of political displacement. Specifically, these depictions show several conflicts that arose from the seeking of identity in Ecuador during the nation-building project that took place at the time. As a result of colonial enterprises (scientific excursions, exile, tourism, journalistic pieces, expeditions, etc.), travel writings of the Galápagos condition the formation of the state and its national imagery because of the extreme symbolic capital of the archipelago and the desire of Latin American intellectuals to belong to a cosmopolitan territory. https://docs.lib.purdue.edu/psrl/1008/thumbnail.jpg

Los llanos Orientales de Colombia u Orinoquia colombiana tienen 17 millones de hectáreas y contienen tres sistemas de tierras o paisajes: el piedemonte, las llanuras aluviales y las altillanuras (los bienes drenados y las inundables). Pertenecen a un microsistema de importancia global (las sabanas tropicales) cuya topografía permite la mecanización agrícola y cuyos suelos exigen un manejo cuidadoso. Su población escasa comprende etnias indígenas y colonos inmigrantes. sus suelos (Oxisoles y Ultisoles) son ácidos y poco fértiles, están sometidos a temperaturas altas durante el año y a excesos de humedad, y se caracterizan por la lixiviación de minerales y por la formación de laterita (gleyzación). Desde hace años, esta sabana herbácea y poco arbustiva se ha destinado a una ganadería extensiva de carga baja. Actualmente manifiesta estos suelos un alto potencial agrícola comercial y han permitido la introducción de especies forrajeras mejoradas. el subsuelo es muy rico en hidrocarburos.

A lo largo de la película, Herzog y sus personajes dan un rol a la Antártida como lugar de deseo y como lugar incomprensible en las narrativas que los personajes cuentan ellos mismos sobre sus propias vidas. Su habilidad para hacer esto es consecuencia del mito popular que muestra la Antártida como un páramo estático y vacío, así como de los modos de gobierno nacionalista que promueven la ciencia pero apartan otras formas de saber hacia la periferia. Los personajes de la película de Herzog están condenados a un ciclo de repetición interminable: forzados por un mito a revivir constantemente el momento del descubrimiento, y restringidos por los modos de gobierno que niegan la expresión formal de la sensibilidad exacerbada que experimentan al encontrarse en el espacio de la Antártida. Por último, este ciclo genera desesperanza y la película lleva a los espectadores hacia una inmersión en los tropos de las fronteras: En lugar del héroe hombre blanco yendo a rescatar a la naturaleza en peligro, encontramos al heroico hombre blanco angustiado con la mirada fija contemplando el vacío imposible. De esta manera, la película de Herzog se convierte en una parábola sobre la historia limitando y refrenando nuevas formas de saber. En una era de cada vez más incertidumbre medioambiental, y con la Antártida actuando como un test de tornasol para el impacto de los humanos en el planeta, así como una evaluación del futuro de la raza humana. "Encounters" nos pide que rechacemos la historia que no nos enseña nada nuevo, y nos pide que encontremos maneras de renovar el gran experimento de vivir en el mundo. Werner Herzog’s 2007 documentary Encounters at the End of the World concerns human ideals of exploration in the extreme environment of the Antarctic. Throughout the film, Herzog and his characters enrol the Antarctic variously as a site of desire and as a site of incomprehensibility in self-told narratives about their own lives. Their ability to do so is a consequence of both popular myth that casts the Antarctic as a static and empty wasteland, and nationalistic modes of governance that promote science but squeeze other modes of knowing to the fringe. The characters in Herzog’s film are thus doomed to a cycle of endless repetition: forced by myth to constantly revisit the moment of discovery, and constrained by modes of governance that deny formal expression of the heightened sensibility they experience when engaging with Antarctic space. Ultimately, this cycle generates despair and so the film bears witness to an inversion of frontier tropes: Instead of heroic white male coming to the aid of nature in distress we instead find the heroic white male in distress staring into an utterly hopeless void. In this way, Herzog’s film becomes a parable about history constraining new forms of knowing. In an age of increasing environmental uncertainty, and with the Antarctic enrolled as both a litmus test for human impacts on the planet, and for gauging the future of the human race, Encounters asks us to reject history where history teaches us nothing new, and it asks us to find ways to renew the great experiment of living in the world.

Wireless power transfer research has been limited to through-air applications, focusing on short distances and high efficiencies. However, complex scenarios require specific design criteria to provide the advantages of wireless power transfer for critical applications. Taking this into consideration, this work presents the extensive research towards enabling wireless power transfer systems for unconventional barriers. In the first chapter a new approach is taken towards the design of compact and embedded wireless power transfer solutions. A miniature coil is designed to transfer power through a 1 mm thick aluminum metal plate. The results are unprecedented, P_rx=100 mW, considering that through metal power transfer had only being demonstrated using large diameter coils. In addition to that, the metal barrier used is aluminum, a high conductivity material. This is important because traditional research focused on less conductive material such as stainless steel or tin. In the next chapter, we demonstrated a wireless power and data transfer system that uses a miniature coil with a size of 15 mm × 13 mm × 6 mm. Our system demonstrated that not only power but data could be transferred through an aluminum barrier using the same coil for power and data transmission. The maximum coil-to-coil power transfer efficiency is 2.4%, and the maximum harvested power is 440 mW operating at 2 kHz. Additionally, our system demonstrated that power can be harvested in variety of materials of different thicknesses. The next chapter presents a breakthrough in the field of wireless power transfer through metal by enabling long distance wireless power transfer. A large portion of the technologies for wireless power transfer are limited to short operation distances, distances around 1-10 millimeters to less than 20 cm. The operation distances are even shorter for the ...

description Publicationkeyboard_double_arrow_right Article 2011 ColombiaPublisher:Universidad de Medellín Authors: Anaya Acevedo, Jesús Adolfo; Chuvieco Salinero, Emilio; Palacios-Orueta, Alicia;La quema de biomasa es una fuente importante de gases efecto invernadero en países en vías de desarrollo. En Colombia, el cambio de uso del suelo, la silvicultura y el sector agropecuario superan el 50% de las emisiones totales de efecto invernadero.El fuego se utiliza con frecuencia como un mecanismo para cambiar el uso del suelo. Los Llanos orientales y la Amazonía colombiana están sometidos todos los años a la quema de biomasa, especialmente entre enero y marzo. Los estudios en la distribución espacial y temporal de las emisiones son importantes de cara a los informes en el ámbito nacional. Este artículo de revisión describe el método para hacer estas estimaciones utilizando teledetección y algunos de los resultados disponibles para Colombia.ABSTRACTBiomass burning is a major source of greenhouse gas emissions in developing countries. In Colombia, land use change, forestry, and agriculture are responsible for more than 50% of the total greenhouse gas emissions. Fire is commonly used as a mechanism for land use change. In Colombia the Llanos Orientales and the Amazonia are subject to biomass burning every year during the dry season, specially from January to March. Studies of the spatial and temporal distribution of emissions are required for emissions report at a national level. The goal of this state of the art article is to describe a method to estimate emissions with a remote sensing approach and to present some of the variables already measured in Colombia.Key words: emissions, remote sensing, biomass, burned area.

Mientras la región se vincula cada vez más con la sociedad nacional de Honduras, varios procesos socioeconómicos están transformando las comunidadesde la reserva. Esta investigación se enfoca en tres comunidades ubicadas a lo largo del límite oriental de la biosfera. Pocas casas todavía están orientadas totalmente en la subsistencia. La mayoría combina la subsistencia con varias otras actividades que rinden el dinero. Este estudio demuestra que la sostenibilidad de la agricultura itinerante no es una cuestión solamente de sus límites ambientales, sino su valor en comparación a otras actividades económicas que existen ahora en la Mosquitia hondureña, así como en otras regiones fronteras de la América Central.Palabras claves: Mosquitia hondureña, río Plátano, sostenibilidad, agricultura itinerante, cambio socioeconómico.AbstractThis article examines the process in which shifting cultivation is becoming marginalized in the Río Plátano Biosphere of the Honduran Mosquitia. As the region becomes increasingly tied to the national society of Honduras, various socioeconomic processes are transforming communities in the reserve.This investigation focuses on three communities located along the eastern boundary of the biosphere.Few houses are still oriented solely on subsistence. The majority combine subsistence with various other money-making activities. This research demonstrates that the sustainability of shifting cultivation is not solely a question of its environmental limits, but also its value in comparison to other economic activities that are now present in the Honduran Mosquitia, as well as in other frontier regions of Central America.Keywords: Honduran Mosquitia, Río Plátano, sustainability, shifting cultivation, socioeconomic change

El argumento principal sugiere que la descripción de este espacio crucial para la modernidad, dada la retórica de los escritores de viajes y ficción, transforma el área insular para concebir formas alternativas del proyecto de construcción nacional en América Latina. Como resultado de las empresas coloniales, excursiones científicas, crónicas periodísticas o expediciones, la escritura de viaje de las Galápagos condiciona la formación del estado y su imaginario nacional. Esto ocurre por el capital simbólico que posee archipiélago y por el deseo de los intelectuales latinoamericanos de pertenecer a un territorio cosmopolita. El espacio insular funciona como un significante vacío donde los viajeros pueden comunicar su propio significado al narrar las experiencias de sus viajes. Este fenómeno crea una división conceptual y política entre la identidad de las islas y la nación ecuatoriana. Dichas ambigüedades narrativas crearon una ruptura que condujo a variaciones fundamentales en la forma en que los habitantes locales y entidades extranjeras interpretan las Galápagos hoy en día, ya que su literatura refleja una tensión particular de cara a las tendencias migratorias en las islas, así como los intereses globales que prevalecen en la apropiación del espacio. This book, written in Spanish, takes a literary and cultural studies model to explain the textual representation of the Galápagos Islands since their discovery until present day. The main argument suggests that the depiction of this crucial space for modernity in Western thought, given the rhetoric of travel and fiction writers, transforms the insular area with the intention of conceiving disparate forms of political displacement. Specifically, these depictions show several conflicts that arose from the seeking of identity in Ecuador during the nation-building project that took place at the time. As a result of colonial enterprises (scientific excursions, exile, tourism, journalistic pieces, expeditions, etc.), travel writings of the Galápagos condition the formation of the state and its national imagery because of the extreme symbolic capital of the archipelago and the desire of Latin American intellectuals to belong to a cosmopolitan territory. https://docs.lib.purdue.edu/psrl/1008/thumbnail.jpg

Los llanos Orientales de Colombia u Orinoquia colombiana tienen 17 millones de hectáreas y contienen tres sistemas de tierras o paisajes: el piedemonte, las llanuras aluviales y las altillanuras (los bienes drenados y las inundables). Pertenecen a un microsistema de importancia global (las sabanas tropicales) cuya topografía permite la mecanización agrícola y cuyos suelos exigen un manejo cuidadoso. Su población escasa comprende etnias indígenas y colonos inmigrantes. sus suelos (Oxisoles y Ultisoles) son ácidos y poco fértiles, están sometidos a temperaturas altas durante el año y a excesos de humedad, y se caracterizan por la lixiviación de minerales y por la formación de laterita (gleyzación). Desde hace años, esta sabana herbácea y poco arbustiva se ha destinado a una ganadería extensiva de carga baja. Actualmente manifiesta estos suelos un alto potencial agrícola comercial y han permitido la introducción de especies forrajeras mejoradas. el subsuelo es muy rico en hidrocarburos.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Article 2015 SpainPublisher:Universidad de Alcalá Authors: Barber, Jacob;El documental "Encounters at the End of the World" (2007) de Werner Herzog reflexiona sobre los ideales humanos de exploración en el medioambiente extremo de la Antártida. A lo largo de la película, Herzog y sus personajes dan un rol a la Antártida como lugar de deseo y como lugar incomprensible en las narrativas que los personajes cuentan ellos mismos sobre sus propias vidas. Su habilidad para hacer esto es consecuencia del mito popular que muestra la Antártida como un páramo estático y vacío, así como de los modos de gobierno nacionalista que promueven la ciencia pero apartan otras formas de saber hacia la periferia. Los personajes de la película de Herzog están condenados a un ciclo de repetición interminable: forzados por un mito a revivir constantemente el momento del descubrimiento, y restringidos por los modos de gobierno que niegan la expresión formal de la sensibilidad exacerbada que experimentan al encontrarse en el espacio de la Antártida. Por último, este ciclo genera desesperanza y la película lleva a los espectadores hacia una inmersión en los tropos de las fronteras: En lugar del héroe hombre blanco yendo a rescatar a la naturaleza en peligro, encontramos al heroico hombre blanco angustiado con la mirada fija contemplando el vacío imposible. De esta manera, la película de Herzog se convierte en una parábola sobre la historia limitando y refrenando nuevas formas de saber. En una era de cada vez más incertidumbre medioambiental, y con la Antártida actuando como un test de tornasol para el impacto de los humanos en el planeta, así como una evaluación del futuro de la raza humana. "Encounters" nos pide que rechacemos la historia que no nos enseña nada nuevo, y nos pide que encontremos maneras de renovar el gran experimento de vivir en el mundo. Werner Herzog’s 2007 documentary Encounters at the End of the World concerns human ideals of exploration in the extreme environment of the Antarctic. Throughout the film, Herzog and his characters enrol the Antarctic variously as a site of desire and as a site of incomprehensibility in self-told narratives about their own lives. Their ability to do so is a consequence of both popular myth that casts the Antarctic as a static and empty wasteland, and nationalistic modes of governance that promote science but squeeze other modes of knowing to the fringe. The characters in Herzog’s film are thus doomed to a cycle of endless repetition: forced by myth to constantly revisit the moment of discovery, and constrained by modes of governance that deny formal expression of the heightened sensibility they experience when engaging with Antarctic space. Ultimately, this cycle generates despair and so the film bears witness to an inversion of frontier tropes: Instead of heroic white male coming to the aid of nature in distress we instead find the heroic white male in distress staring into an utterly hopeless void. In this way, Herzog’s film becomes a parable about history constraining new forms of knowing. In an age of increasing environmental uncertainty, and with the Antarctic enrolled as both a litmus test for human impacts on the planet, and for gauging the future of the human race, Encounters asks us to reject history where history teaches us nothing new, and it asks us to find ways to renew the great experiment of living in the world.

For further information contact us at helpdesk@openaire.eudescription Publicationkeyboard_double_arrow_right Thesis 2023 United StatesPublisher:eScholarship, University of California Authors: Romero Arguello, Juan Manuel;This works presents the design of wireless power transfer systems that can transfer power through materials such as stainless steel, aluminum, carbon fiber, and fiberglass. Wireless power transfer research has been limited to through-air applications, focusing on short distances and high efficiencies. However, complex scenarios require specific design criteria to provide the advantages of wireless power transfer for critical applications. Taking this into consideration, this work presents the extensive research towards enabling wireless power transfer systems for unconventional barriers. In the first chapter a new approach is taken towards the design of compact and embedded wireless power transfer solutions. A miniature coil is designed to transfer power through a 1 mm thick aluminum metal plate. The results are unprecedented, P_rx=100 mW, considering that through metal power transfer had only being demonstrated using large diameter coils. In addition to that, the metal barrier used is aluminum, a high conductivity material. This is important because traditional research focused on less conductive material such as stainless steel or tin. In the next chapter, we demonstrated a wireless power and data transfer system that uses a miniature coil with a size of 15 mm × 13 mm × 6 mm. Our system demonstrated that not only power but data could be transferred through an aluminum barrier using the same coil for power and data transmission. The maximum coil-to-coil power transfer efficiency is 2.4%, and the maximum harvested power is 440 mW operating at 2 kHz. Additionally, our system demonstrated that power can be harvested in variety of materials of different thicknesses. The next chapter presents a breakthrough in the field of wireless power transfer through metal by enabling long distance wireless power transfer. A large portion of the technologies for wireless power transfer are limited to short operation distances, distances around 1-10 millimeters to less than 20 cm. The operation distances are even shorter for the ...
