LA IMAGEN TURÍSTICA DE LAS REGIONES INSULARES: LAS ISLAS COMO PARAÍSOS
The problems of the islands constitute a theoretical solid body analyzed from different disciplines, economy, geography, ecology, etc. One of the main problems of the islands is the shortage of economic resources that not only allow a development economic, but a sustainable development. In this context the tourism is constituted in an economic agent and of vital development for these regions. Now then this relationship island-tourism presents characteristic own and complex. In this article we seek to explore the tourist image of the islands, how they are built and that consequences are derived. Los problemas de las islas constituyen un sólido cuerpo teórico analizado desde diferentes disciplinas, economía, geografía, ecología, etc. Uno de los problemas principales de estas regiones es la escasez de recursos económicos que permitan un desarrollo, no sólo en términos de economía, sino un desarrollo sostenible1. El turismo se constituye por tanto como un agente económico y de desarrollo que las regiones insulares no pueden permitirse desaprovechar. Ahora bien, esta vinculación turismo-islas, presenta características propias y complejas. En este artículo pretendemos explorar la importancia de la imagen turística de las regiones insulares, cómo se construye y cuáles son la consecuencias derivadas de este tipo de imagen turística y no de otra
Turismo y gestión cultural en las Islas Canarias: apuntes para una reflexión
Las Islas Canarias constituyen un claro ejemplo de región que debe su nivel de desarrollo a la
actividad turística. La andadura turística se inicia en la década de los sesenta, vinculada al modelo turístico
de la época, el turismo de masas asociado a sol y playa (materias primas abundantes). Desde entonces
hasta ahora han transcurrido bastantes cambios. En la actualidad intenta complementar su oferta
turística ofreciendo turismo rural (por utilizar un nombre genérico) y también, aunque menos desarrollado,
turismo cultural. Plantear algunas reflexiones sobre el turismo cultural en Canarias, en especial las
dificultades derivadas de su gestión, es el objetivo de este artículo.Canary Islands are an example of developed region and clerk of the tourism, from the sixty
(tourism of sun and beach). From then on until the present time they have happened enough changes. At
the moment it is tried to supplement their offer with the rural tourism and the cultural tourism. To outline
some reflections about the cultural tourism, especially the difficulties of their management, it is the objective
of this article
Nuevos turistas en busca de un nuevo producto: El patrimonio cultural
La actividad turística experimenta cambios. En la actualidad los turistas demandan naturaleza
y cultura, no sólo sol y playa. Nuevos turistas y por tanto nuevos productos turísticos, aparecen en escena.
Analizar algunas de las consecuencias asociadas con la proliferación del turismo cultural es el objetivo
de este artículo.The tourism is dynamic. At the present time, the tourists want nature and culture, not only sun
and beach. New tourists and new products (Cultural tourism) appear. To analyze some of these consequences
is objetive of this article

HCV-coinfection is related to an increased HIV-1 reservoir size in cART-treated HIV patients: a cross-sectional study
In HIV-1/HCV-coinfected patients, chronic HCV infection leads to an increased T-lymphocyte immune activation compared to HIV-monoinfected patients, thereby likely contributing to increase HIV-1 reservoir that is the major barrier for its eradication. Our objective was to evaluate the influence of HCV coinfection in HIV-1 viral reservoir size in resting (r) CD4+ T-cells (CD25-CD69-HLADR-). Multicenter cross-sectional study of 97 cART-treated HIV-1 patients, including 36 patients with HIV and HCV-chronic co-infection without anti-HCV treatment, 32 HIV patients with HCV spontaneous clearance and 29 HIV-monoinfected patients. rCD4+ T-cells were isolated and total DNA was extracted. HIV viral reservoir was measured by Alu-LTR qPCR. Differences between groups were calculated with a generalized linear model. Overall, 63.9% were men, median age of 41 years and Caucasian. Median CD4+ and CD8+ T-lymphocytes were 725 and 858 cells/mm3, respectively. CD4+ T nadir cells was 305 cells/mm3. Proviral HIV-1 DNA size was significantly increased in chronic HIV/HCV-coinfected compared to HIV-monoinfected patients (206.21 ± 47.38 vs. 87.34 ± 22.46, respectively; P = 0.009), as well as in spontaneously clarified HCV co-infected patients when compared to HIV-monoinfected individuals (136.20 ± 33.20; P = 0.009). HIV-1/HCV co-infected patients showed a larger HIV-1 reservoir size in comparison to HIV-monoinfected individuals. This increase could lead to a greater complexity in the elimination of HIV-1 reservoir in HIV-1/HCV-coinfected individuals, which should be considered in the current strategies for the elimination of HIV-1 reservoir.The authors thank all the patients for their participation.

El dossier copia/sur: problemas económicos, políticos, e ideológicos del copyright (derecho de autor) en el sur global
In 2005, a group of scholars and activists, mostly from the global South, created the Copy/South Research Group to analyse, criticise, and confront the oppressive nature of current global copyright regimes, such as those
defended by the World Intellectual Property Organisation, and similar ones around the globe. In May 2006, 22 of us, including 15 people from the global South, published THE COPY/SOUTH DOSSIER: Issues in the economics, politics, and ideology of copyright in the global South.
The aim of the Dossier was to open up a critical and radical debate on the real impact of copyright laws and how they affect the daily lives of people living in more than 150 developing countries of the global South. We also highlighted issues that are not unique to the Global South, but also affect both sides of the North-South divide. This publication of more than 50 articles was addressed to researchers, educators, librarians, musicians, activists, organizations concerned about access to knowledge, and all of those who want to learn more about the oppressive global role of copyright laws and, in particular, their largely negative role in the developing countries of the global South.
Given the democratic objectives of the Copy/South Research Group, the Dossier was not restricted by copyright. Therefore, it has been accessed openly and freely in both electronic and paper formats by thousands of readers from around the world in English. But English is not spoken by all citizens in the global South. With this in mind, the entire 200-page Dossier was translated into Spanish in late 2007 by an enthusiastic team of voluntary translators from Argentina, Bolivia, Cuba, Mexico, Spain, and Venezuela.
As for this Spanish version, made with the support of the Intellectual Property Automous Service (SAPI), from the Bolivarian Republic of Venezuela, we must acknowledge the prior SAPI's General Director Eduardo Samán for promoting the making of this translation. Besides the general revision of Gerardo Cárdenas and his labor as main translator, some other volunteers translated or revised important sections of the Spanish edition: María Jesús
Morillo (Spain), Oscar Pérez Peña and Gilda Gil (Cuba), Edgardo Civallero (Argentina) and Rafael Carreño (Venezuela), who coordinated the process of translation in 2007. Also it is worth to mention the additional colaboration of Ana Lía López (Bolivia), Richard Castro, Rafael Bellota and Carmen Chirinos (Venezuela), Zapopan Muela and Gonzalo Lara (Mexico), and Lilian Álvarez (Cuba).
But what is still more extraordinary about this Spanish translation is that it was completely coordinated and edited by the Servicio Autonomo de la Propiedad Intelectual (SAPI) of the democratic government of the Venezuelan Bolivarian Republic. The Dossier provides “useful material to introduce this topic to teachers and students” and does a good job of “summarizing a complex and conflicting situation” for developing countries, Jumersi La Rosa, SAPI’s new director, said last week in announcing the release of the Spanish edition. She has written a special
new introduction for the Spanish-language edition.
The Copy South Research Group is very pleased that the radical message of resistance found in the Dossier can now be read by thousands of Spanish-language speakers who are questioning the current copyright regime and who hopefully will be ignited by the ideas in the Dossier to take up
the fight against oppressive regimes based on copyright.
You can get a copy of the Dossier in Spanish and English by downloading it, free of charge, at http://www.copysouth.org . We also still have a limited number of printed and bound copies of the English-language version of the Dossier. If you would to be mailed a copy of the English-language version, which contains eight posters, send us an e-mail ([email protected]) and include your full postal details.

Aplicación de enmiendas orgánicas producidas a partir de residuos agrícolas en suelos calcáreos
Resumen de la comunicación oral presentada en RENS 2023 XXXIII Reunión Nacional de Suelos. Pamplona, del 12-15 de septiembre 2023 .- El libro de resúmenes lo puede descargar en https://www2.unavarra.es/gesadj/seccionActualidad/congresos/rens2023_libro_resumenes.pdfLa agricultura actual se enfrenta al reto de garantizar el suministro de alimentos a una población en continuo crecimiento mientras la actividad humana ya ha deteriorado sobre el 40% de los suelos cultivables del planeta, aumentando la dependencia de los fertilizantes minerales. En este contexto, la valorización de residuos agrícolas para utilizarlos como sustratos o suplementos del suelo se propone como alternativa, creando además una solución a la generación masiva de residuos orgánicos agro-ganaderos. Este trabajo muestra las propiedades físicas de interés agrnómico y la composición (macro y micronutrientes) de biochars, composts y cenizas producidas a partir de restos vegetales de las agroindustrias olivadera y des arroz, y los efectos de su aplicación a los suelos calcáreos (Xerochrept y Luvisol) bajo condiciones de clima mediterraneo. Las enmiendas mostraron atributos apropiados para mejorar las propiedades agronómicas del suelo. El biochar mostró una alta aromaticidad y abundancia de C orgánico estable. Las enmiendas ricas en ceniza mostraron altos contenidos en P y K y micronutrientes. El compost presento una elevada capacidad de retención de agua y un adecuado balance de C y N. Todas las enmiendas orgánicas redujeron la hidrofobicidad del suelo. La aplicación de biochar consiguió aunmentar la humedad del suelo en los primeros 10 cm y reducir su compactación, los que se evidencio por la reducción significativa de la resistencia del suelo a la penetrabilidad. Las plantas de las parcelas enmendadas mostraron un mejor potencial hídrico foliar. Además, los valores de la tasa de fotosíntesis neta, la eficiencia media de uso del agua intrínseca y la tasa máxima del transporte de electrones en el momento de la cosecha mejoraron significativamente en los árboles de las parcelas enmendadas con una dosis de biochar de 40 t ha-1. En relación al ciclo de C, la adición de compost incrementó de manera significativa la respiración (emisión de CO2) y la cantidad de C procedente de microorganismos. El uso de biochar por su parte, incrementó el contenido en materia orgánica estable en los primeros 5 cm de suelo y redujo la abundancia total de microorganismos 2 años después de su aplicación.Al Ministerio de Ciencia e Innovación y a la Agencia Estatal de Investigación (AEI) por la financiación del proyecto AGRORES (PID2021-1263490B-C22).N
