    Full Text Available El crepúsculo de enero del año de 1935 vio extinguirse la vida de Jaime Barrera Parra, uno de los espíritus más selectos que ilustraron el periodismo colombiano. Fue elemento de selección original dentro del común trajinar de las máquinas y las rotativas que esparcen el pensamiento a través de los periódicos por todos los ámbitos voraces del país.

  2. La pintura de flores de Miguel Parra (1780-1846

    Directory of Open Access Journals (Sweden)

    López Terrada, María José

    2013-06-01

    Full Text Available Although Miguel Parra Abril (Valencia, 1780-Madrid, 1846 is one of the most important Valencian School painters of floral still lifes, this aspect of his work remains little known. The present article addresses this oversight in two ways. First, by offering an overview of his oeuvre as a painter of floral subjects from his student days at the Fine Arts Academy of Valencia through his mature works. Second, by analyzing two heretofore-unpublished floral compositions in relation to his more familiar works, particularly those located in private collections until recent years.Aunque Miguel Parra Abril (Valencia, 1780-Madrid, 1846 es uno de los pintores de flores más importantes de la Escuela valenciana, esta faceta pictórica de su producción es todavía poco conocida. El presente artículo trata de paliar esta situación ofreciendo, en primer lugar, una visión general de su obra como pintor de flores desde su proceso de aprendizaje en la Academia de Bellas Artes valenciana hasta sus composiciones de madurez. En segundo lugar, se presenta el análisis de dos composiciones florales inéditas y su relación con las obras conocidas hasta el momento, especialmente con aquellas que hasta hace pocos años se encontraban en colecciones particulares.

  3. DOS METONIMIAS DE NERUDA Y PARRA: EL BOLERO Y LA CUECA

    2011-09-01

    Full Text Available Bolero y cueca se proponen como metonimias de una prosodia y sintaxis poética empleada por Neruda en Veinte poemas de amor y una canción desesperada y por Parra en La cueca larga y Artefactos. Trabajo fundamentalmente con el ritmo y la melodía de los versos superando la división entre lengua y música."La cueca" and "el bolero" are musical forms proposed as metonymies of a poetic prosody and syntax in Neruda's Veinte poemas de amor y una canción desesperada, and in Parra's La cueca larga and Artefactos. This work focuses mainly on the rhythmic and melodic substance of the verses, thus surpassing a division between language and music.

  4. El poeta Ernesto López-Parra excomulgado del ultraísmo

    Directory of Open Access Journals (Sweden)

    Rojas Sánchez, Pablo

    2009-06-01

    Full Text Available Spanish Ultraism had as a main goal to leave behind Modernism. Many poets that take part in that movement had been previously modernists, and that infects many of their poems. Ultraism, like Futurism, hates tradition. In spite of all that there are some heterodox ultraists: Gerardo Diego, for example, didn’t repudiate the past. Neither does Ernesto López-Parra. Both collaborate in Vltra, a magazine which tries to purge Ultraism of indecisive writers. The release of Paisaje de abanico provokes the expulsion of Lopez-Parra from its pages. That gesture relates Spanish Ultraism with International avant-garde. The end of Vltra is the end of Ultraism. After that, new and more plural magazines appear, promoted in many occasions by all those who were especially fierce in the persecution of dilettante poets.El ultraísmo español quiso superar al modernismo precedente. Muchos poetas ultraístas procedían de él, y eso se aprecia en sus composiciones. El ultraísmo, como el futurismo, era poco complaciente con la tradición. Sin embargo, no faltaron ultraístas heterodoxos: Gerardo Diego, por ejemplo, no despreció la voz del pasado. Tampoco Ernesto López-Parra. Ambos colaboran en Ultra, una revista nacida para depurar al ultraísmo de elementos vacilantes. El estreno de Paisaje de abanico provoca la expulsión de López-Parra de sus páginas. Este gesto enlaza el ultraísmo con parecidas actitudes sectarias propias de la vanguardia internacional. La desaparición de Ultra marca el fin del movimiento. Tras ella nacen revistas más plurales paradójicamente promocionadas por los vanguardistas más ortodoxos.

  5. Disparates religiosos y políticos en la poesía de Nicanor Parra

    Directory of Open Access Journals (Sweden)

    José Alberto de la Fuente

    2007-01-01

    Full Text Available El poeta chileno Nicanor Parra (1914, autodenominado antipoeta y por ende su discurso de antipoesía, desde hace más de medio siglo, su poesía y su persona, suscitan controvertidos juicios: indignación, indiferencia, entusiasmo, aplausos, abucheos, negación, etc. El propósito de este trabajo es hacer una lectura -a modo de anticipo- en clave religiosa y política de su obra reunida en el primer volumen de sus Obras Completas (2006, y de otros libros difundidos después de 1972. La dimensión religiosa y la política del antipoeta se estructura con una lógica bipolar y con un sustrato de cultura popular en el contexto de una modernidad en franca crisis de paradigmas. Algunos críticos han llegado a afirmar que Nicanor Parra es el mejor poeta vivo de Occidente, de lo cual debería inferirse que es un fiel representante de la historia fenomenológica del siglo XX. ¿Es sostenible esta consideración?.The Chilean poet Nicanor Parra (1914, his poetry and his person, provoke controversial judgments in the reader and critics. The purpose of this work is to make an interpretation -as a preview- from the religious and political point of view of his work compiled in the first volume of his Complete Works (2006 and from other books published after 1972. The religious and political dimension of this anti-poet is structured with a bipolar logic with a popular culture in the context of a modernity which goes through a paradigm crisis. Some critics have come to claim that Parra is the best living poet of the western world, from which we should infer that he is the loyal representative of the phenomenological history of the XX century. Is this claim sensible?.

  6. Chistes par(ra reordenar el canon: Roberto Bolaño, Nicanor Parra y la poesía chilena

    Directory of Open Access Journals (Sweden)

    Benjamin Loy

    2014-12-01

    Full Text Available “Todo se lo debo a Parra” – con estas y semejantes palabras de elogio Roberto Bolaño le asignó un lugar central al antipoeta chileno dentro de su amplio canon personal. No obstante, la amplia crítica bolañiana hasta el momento no pareciera haber estudiado a fondo las múltiples dimensiones de esta relación entre los dos autores chilenos. El presente estudio pretende analizar, por lo tanto, de qué manera los postulados ético-estéticos de Parra y de su antipoesía le sirven a Bolaño como punto de referencia clave para reordenar el canon de la literatura chilena contemporánea. Además, se discutirá el papel clave que desempeña Bolaño en el renovado interés de la crítica en la obra de Nicanor Parra durante los últimos años.

  8. Ironía y descentramiento en los Artefactos de Nicanor Parra y Guillermo Tejeda

    Directory of Open Access Journals (Sweden)

    Gabriel Villaroel

    2014-01-01

    Full Text Available En este artículo se desarrollará la heterogénea pluralidad de pensamiento que reina en las frases de los Artefactos en relación con las imágenes de Guillermo Tejera y la necesidad de estudiarlas como parte de un mismo proyecto. Nicanor Parra utiliza una distancia irónica de su “yo” para esgrimir en su obra una amplia y contradictoria gama de ideas que encuentran un nuevo desarrollo en el diseño visual que las enmarca. Las imágenes permiten abrir nuevos significantes dentro de la subversión del discurso poético operada por el chileno. Para desarrollar este tema, se utilizará como principal ejemplo la irreverencia del poeta frente a la política de izquierda y derecha durante los álgidos y comprometidos años setenta.

    Directory of Open Access Journals (Sweden)

    Carla Pinochet Cobos

    2010-06-01

    Full Text Available La obra artística de Violeta Parra presenta, en diversos niveles, una compleja problematización de los esquemas sociales de la primera mitad del siglo XX. Este trabajo busca examinar los modos en los que esta folclorista transita por los esquemas de género que recaían sobre los hombres y mujeres de la época, dando lugar a una mirada crítica e irreverente en la que la tradición cultural y la innovación confluyen, tanto en lo que respecta al contenido de sus textos como en el plano expresivo de su musicalidad.Violeta Parra's artistic work presents on different levels the complex problem of unraveling the social schemes of the first half of the twentieth century. This article examines the ways in which this "folclorista" moved through the gender schemes corresponding to men and women of that epoch. This movement opened a space for a both critical and irreverent view in which cultural tradition and innovation converge, both regarding the contents other texts as well as the expression of their musicality.

    Full Text Available El presente estudio muestra las evidencias de deformación neotectónica en la región del noroeste argentino de lomas de Olmedo, provincia de Salta. Esta región ubicada en el frente orogénico a los 24°S de latitud comprende la zona de transición entre las Sierras Subandinas al norte, de tipo epidérmico con vergencia al este, o Sistema Subandino sensu stricto, y un segmento austral correspondiente al Sistema de Santa Bárbara producido por inversión tectónica de fallas normales con vergencia al oeste. Entre estos dos segmentos con diferente comportamiento se ubican las lomas de Olmedo, que muestran un complejo diseño de fallas activas. Depósitos de edad paleógena que constituyen las facies de hundimiento térmico de las fases finales del rift del Grupo Salta y los depósitos sinorogénicos neógenos de la cuenca de antepaís subandina, se hallan plegados y corridos sobre depósitos cuaternarios en el anticlinal de lomas de Olmedo. Los sedimentos terciarios están corridos sobre los depósitos lacustres de la Formación El Chorro de edad cuaternaria. Las edades 14C en conchillas de gasterópodos de esta unidad pertenecientes a Pomacea canaliculata arrojaron una edad de 7.962 ± 45 BP años para estos depósitos. Las fallas inversas con vergencia al este indican para la mayor parte del Holoceno una tasa de acortamiento orogénico de 2,34 mm/a para el frente tectónico en la zona de transición entre los dos sistemas de la faja plegada y corrida subandina.

During the last third of the nineteenth century, the national demand for alcoholic beverages increased, augmenting Parras' economical importance. Several harvesters embarked on modernizing processes, and among them the Madero family stood out. However, upon attempting to diversify the varieties of vitis vinifera, they brought the filoxera to the Valley. The centuries-old Parras varieties were destroyed by the pest, and the technique of grafting had to be introduced. Thanks to their opulence and strategic position in political and business networks, the Maderos managed to overcome the crisis and allowed one of the most ancient wine-producing enterprises in Mexico to remain productive.

    Full Text Available The native tree Schinus molle (Anacardiacae is reported for the first time as a host plant for larvae of the little known geometrid moth Eupithecia yubitzae Vargas & Parra (Lepidoptera, Geometridae in the Atacama Desert of northern Chile, based on morphology and DNA barcodes. This discovery importantly expands the host range of E. yubitzae, as previous records were restricted to Fabaceae trees. Larvae were previously known as florivorous, while these were found to be folivorous on S. molle. Furthermore, host-associated cryptic larval polychromatism was detected, as larvae collected on S. molle were found to be mostly pale green, contrasting with the dark yellow ground color of the larvae typically collected on fabaceous host plants.

    Full Text Available El objetivo del presente artículo es aportar algunas reflexiones sobre la obra Canto para una semilla del compositor chileno Luis Advis (1972, fundamentalmente a partir de sus dimensiones culturales e históricas. El significado de esta obra es observado en relación con los debates y cuestionamientos a los que se ve enfrentado el compositor en la sociedad chilena durante las décadas de 1960 y 1970, los cuales se constituyen como expresión de las transformaciones provocadas por la modernización en nuestro país. Esta experiencia concreta de la modernidad se ve reflejada en el contenido poético de las décimas de Violeta Parra, que constituyen el soporte dramático de la obra de Luis Advis, así como también en las vinculaciones entre música culta y música popular, que darán origen posteriormente a la Nueva Canción Chilena y, con ello, redefinirán también el lugar que la música popular posee en nuestra sociedadThis article is a study of the piece Canto para una semilla (Song for a Seed by the Chilean composer Luis Advis (1972, primarily in its cultural and historical dimensions. The meaning of the work is sought in its interrelations with the problems and debates within the Chilean society of the 1960s and 1970s, which were related to the transformations brought about by modernization in Chile. This is mirrored in the poetic content of the décimas written by Violeta Parra, which constitute the dramatic support for Luis Advis's work. This is further related to the connections between art music and popular music which will later originate the Nueva Canción Chilena (New Chilean Song this redefining the place of popular music in our society

Teatro y escenificación de la memoria, no es sino la puesta en el drama de una gran metáfora epistemológica, en la terminología de Umberto Eco, pues nos da una imagen de discontinuidad, que permite confirmar la apreciación de un mundo que se experimenta fragmentado, pero que se intenta recomponer en una imagen totalizadora.The development of this work, show us the memory and the remenbrance breaking, when the History is experimented like a breach and oscillation, mouving between its possible and its failure, with characters whose imaginery try to remain in the reality, that has been permeated and displaced for the dynamic of social events.

    2013-03-01

    Full Text Available El libro, en términos generales, aborda el contexto social, cultural y político en el que se realizó la II Conferencia General de Episcopado Latinoamericano en Medellín, Colombia. Esta conferencia, que se celebró entre el 26 de agosto y el 6 de septiembre de 1968, reunió a invitados, comitivas, periodistas y numerosos turistas de todo el mundo. Como exponen los autores, la Conferencia constituye un acontecimiento de indudable importancia tanto para la historia política latinoamericana, como para la historia eclesiástica y para la historia de la ciudad pese a lo cual, en nuestro medio, ha sido tratada tangencialmente por pocas personas, como Javier Darío Restrepo, Hernán Parada y Clara Aramburo. La obra es de carácter historiográfico, pero logra incorporar aspectos narrativos de la memoria biográfica colectiva y de la crónica. Es decir, contiene el rigor argumentativo de un texto académico, pero está expuesto de una manera sencilla, clara, que además resulta agradable visualmente, al alcance tanto del público especializado como de lectores interesados en una época convulsa y conflictiva para Medellín y para buena parte del mundo occidental.

    Viscous flow analysis in a radial impulse turbine for OWC wave energy systems

    2007-07-01

    The Oscillating Water Column system (OWC) is considered as interesting concept for ocean wave energy extraction. Several kinds of air turbines have been envisaged for pneumatic energy conversion to mechanical energy. The Wells turbine has been used widely in OWC plants. However an alternative self-rectifying turbine called Impulse turbine has gained more attention last years. In the present study, we are interested in the radial version of the Impulse turbine, which was initially proposed by McCormick. This numerical study is aimed to improve the understanding of the local flow behaviour inside a radial version of the Impulse turbine and the prediction of its performances. The research work has been carried out using FLUENT(reg sign) code. Model validation has been conducted through a comparison with experimental results available in the literature. It is planed that this model will be exploited next in the design and the optimisation stages of a high performances radial Impulse turbine project for an OWC of 250 kW.

    2006-10-01

    Berry, Trimble, and Olmedo's (1986) acculturation model was used to investigate the relationship among adolescents' acculturation strategies, personal self-esteem, and collective self-esteem. Using data from 427 high school students, factor analysis results distinguished Collective Self-esteem Scale constructs (Luhtanen & Crocker, 1992) from both ethnic identity and outgroup orientation subscales of the Multigroup Ethnic Identity Measure (Phinney, 1992). Subsequent results showed that: 1) both acculturation dimensions were correlated with personal and collective self-esteems, 2) integrationists shared similar levels of personal and collective self-esteems with assimilationists and/or separationists, and 3) marginalizationists generally had the lowest levels of personal and collective self-esteems. Implications are drawn for understanding acculturation among adolescents and for the utility of group-level measures of self-esteem.

  14. Differences on soil organic carbon stock estimation according to sampling type in Mediterranean areas

    Science.gov (United States)

    Parras-Alcántara, Luis; Lozano-García, Beatriz

    2016-04-01

    Soil organic carbon (SOC) is an important part of the global carbon (C) cycle. In addition, SOC is a soil property subject to changes and highly variable in space and time. Consequently, the scientific community is researching the fate of the organic carbon in the ecosystems. In this line, soil organic matter configuration plays an important role in the Soil System (Parras-Alcántara and Lozano García, 2014). Internationally it is known that soil C sequestration is a strategy to mitigate climate change. In this sense, many soil researchers have studied this parameter (SOC). However, many of these studies were carried out arbitrarily using entire soil profiles (ESP) by pedogenetic horizons or soil control sections (SCS) (edaphic controls to different thickness). As a result, the indiscriminate use of both methodologies implies differences with respect to SOC stock (SOCS) quantification. This scenario has been indicated and warned for different researchers (Parras-Alcántara et al., 2015a; Parras-Alcántara et al., 2015b). This research sought to analyze the SOC stock (SOCS) variability using both methods (ESP and SCS) in the Cardeña and Montoro Natural Park (Spain). This nature reserve is a forested area with 385 km2 in southern Spain. Thirty-seven sampling points were selected in the study zone. Each sampling point was analyzed in two different ways, as ESP (by horizons) and as SCS with different depth increments (0-25, 25-50, 50-75 and 75-100 cm). The major goal of this research was to study the SOCS variability at regional scale. The studied soils were classified as Phaeozems, Cambisols, Regosols and Leptosols. The results obtained show an overestimation of SOCS when SCS sampling approach is used compared to ESP. This supports that methodology selection is very important to SOCS quantification. This research is an assessment for modeling SOCS at the regional level in Mediterranean natural areas. References Parras-Alcántara, L., Lozano-García, B., 2014

Mediante la investigación basada en la imagen, subyace como principal conclusión que a pesar de los esfuerzos realizados en la institución universitaria por cambiar hacia un modelo de aprendizaje constructivista, aún no está asumido completamente por los y las estudiantes, puesto que las modalidades de aprendizaje menos representadas son propias a este. El género no se ha incluido como orientador en las nuevas teorías y metodologías universitarias; las mujeres tratan de adaptar y reconfigurar el espacio a las necesidades demandadas por las nuevas acciones, haciéndolos más versátiles, y los hombres más conservadores y reafirmados en modalidades de carácter prioritariamente individuales, situadas en entornos tradicionales de aprendizaje como es un aula o su habitación de estudio.

    Soil organic carbon (SOC) is extremely important in the global carbon (C) cycle; also, SOC is a soil property subject to changes, inasmuch as SOC is highly variable in space and time. The scientific community is researching the fate of the organic carbon in the ecosystems and this is why there is a blooming interest on this topic (Oliveira et al., 2014; Kukal et al., 2015). Soil organic matter play a key role in the Soil System (Fernández-Romero et al., 2014; Parras-Alcántara and Lozano García, 2014; Lozano-García and Parras-Alcántara; Parras-Alcántara et al., 2015).Globally it is known that soil C sequestration is a strategy to mitigate climate change. Over time, some researchers have analyzed entire soil profiles (ESP) by pedogenetic horizons and other researchers have analyzed soil control sections (SCS) (edaphic controls to different thickness), and in each case the benefits of the methodology established was justified. However, very few studies compare both methods (ESP versus SCS). This research sought to analyze the SOC stock (SOCS) variability using both methods (ESP and SCS) in The Despeñaperros Natural Park, a nature reserve that consists of a 76.8 km2 forested area in southern Spain. The park is in a Mediterranean environment and is a natural area (free of human disturbance). Thirty-four sampling points were selected in the study zone. Each sampling point was analyzed in two different ways, as ESP (by horizons) and as SCS with different depth increments (0-25, 25-50, 50-75 and 75-100 cm). The major goal of this research was to study the SOCS variability at regional scale. The studied soils were classified as Phaeozems, Cambisols, Regosols and Leptosols. The total SOCS in the Despeñaperros Natural Park was over 28.2% greater when SCS were used compared to ESP, ranging from 0.8144 Tg C to 0.6353 Tg C respectively (1 Tg = 10E12 g). However, when the top soil (surface horizon and superficial section control) was analyzed, this difference increased to

    Full Text Available El presente estudio correlacional forma parte de una investigación sobre el constructo de “estar quemado” tal y como lo entendieron inicialmente Maslach y Jackson. En este trabajo nos centramos en la relación que el constructo tiene con el afrontamiento. Se aplicó el Cuestionario de Burnout para enfermería (CBE de Hernández, Olmedo y Fernández y el Ways of Coping Questionnaire (WOCQ de Folkman y Lazarus a una muestra de personal sanitario de 222 participantes, de los cuales 187 son mujeres y 35 son varones. Los resultados de los análisis correlacionales, de regresión múltiples y los efectuados para grupos criterio (“altos” frente a “bajos” en los factores de “estar quemado” indican pocas relaciones y de escasa magnitud entre los dos constructos, si bien estos van en la línea de trabajos previos planteándose la necesidad de recurrir a otras variables de tipo personal para explicar el fenómeno del “estar quemado”.

    Full Text Available This article forms part of research in progress that aims to examine the intellectual climate prevailing in Mexico in the post-revolutionary period, from 1920 to 1930. The essay explores how the influence of nationalist ideology gradually shifted the role of Mexican women, identifying them as the educators of the nation. The study focuses on Baja California since educators, such as Josefina Rendón Parra (1885-1977, were an important example illustrating how nationalist ideology engineered women´s role in Mexico´s reconstruction. Education with a spiritual dimension was the key doorway through which women gained access to the modern era. In a society that had yet to grant them the right to vote, education was also the doorway through which women gained acceptance as citizens. Finally, this study proposes the remaking of history through the mythological discourses, such as the legends that were fashionable in that period.

    We show in this Response that the nonlinear Poisson's equation in our original paper derived from the drift kinetic approach can be verified by using the nonlinear gyrokinetic Poisson's equation of Dubin et al. [Phys. Fluids 26, 3524 (1983)]. This nonlinear contribution in φ2 is indeed of the order of k4⊥ in the long wavelength limit and remains finite for zero ion temperature, in contrast to the nonlinear term by Parra and Catto [Plasma Phys. Control. Fusion 50, 065014 (2008)], which is of the order of k2⊥ and diverges for Ti → 0. For comparison, the leading term for the gyrokinetic Poisson's equation in this limit is of the order of k2⊥φ,

  15. Effects of inhomogeneities and drift on the dynamics of temporal solitons in fiber cavities and microresonators

    2014-01-01

    In Ref. [Parra-Rivas at al., 2013], using the Swift-Hohenberg equation, we introduced a mechanism that allows to generate oscillatory and excitable soliton dynamics. This mechanism was based on a competition between a pinning force at inhomogeneities and a pulling force due to drift. Here, we study the effect of such inhomogeneities and drift on temporal solitons and Kerr frequency combs in fiber cavities and microresonators, described by the Lugiato-Lefever equation with periodic boundary conditions. We demonstrate that for low values of the frequency detuning the competition between inhomogeneities and drift leads to similar dynamics at the defect location, confirming the generality of the mechanism. The intrinsic periodic nature of ring cavities and microresonators introduces, however, some interesting differences in the final global states. For higher values of the detuning we observe that the dynamics is no longer described by the same mechanism and it is considerably more complex.

    Full Text Available This work analyzes the transformations that exist in the representation of the individual identity in the Mexican narrative works published between 1995 and 2010 by the writers: Guillermo Fadanelli, Carlos Fuentes, Patricia Laurent Kullick, Héctor Manjarrez, Eduardo Antonio Parra, Aline Pettersson, Pedro Ángel Palou, Xavier Velasco y Socorro Venegas. The article has a general perception with the aim of emphasizing, from the individual poetics, the process of symbolization of the “I” in the Mexican narrative from the beginnings of the 21st century, that as cultural phenomenon unfolds in the borders of literariness and society. The theoretical perspective that encourages the analysis starts off, mainly, from the proposal of the North American psychologist Kenneth Gergen, the sociologist Zigmunt Bauman and the mythocritic proposal of Gilbert Durand.

    Soil organic carbon (SOC) is formed through the decomposition processes of plant, animal and microbial residues, root exudates, living and dead microorganism and soil biota; and is the main energy source for soil microorganism. Consequently, a strong feedback is stablished among a large number of components in the complex biota-abiota network. Likewise, SOC influences in physical, chemical and biological soil properties such as temperature, cationic exchange capacity and plant growth (Parras-Alcántara et al., 2015). Therefore, to improve our knowledge about what soil variables are more responsible of SOC content would be extremely useful in soils characterization. In many studies, independent variables were related to SOC, however, the possible combined effects of different independent variables and their ability to model SOC have not been considered. On the other hand, over the last few decades interest in soil organic carbon (SOC) has increased due to its role in C sequestration in terrestrial ecosystems, which could contribute to decreasing atmospheric CO2 levels (Lozano-García et al., 2016; Fernández-Romero et al., 2016; Parras-Alcántara and Lozano-García 2014). Then, attempts to model SOC content have multiplied over this time. In this study, 612 soil profiles obtained from the Natura 2000 network of protected areas in the Sierra Morena mountains, (Spain) were used with the following objectives: i) To quantify SOC content according to different variables (analytical, morphological, genetic and climatic) in order to define the variables that are most closely related to SOC content; ii) To model the Current SOC content for a geographic area (Sierra Morena - Spain); iii) To model SOC suitability-habitat under a climate change scenario; iv) To extrapolate the SOC content and distribution model to the wider Andalusia region, showing the areas that have a high probability to experience an increase in their SOC content in coming years; and v) To propose

    To assess the impact of climate change on soil organic C (SOC) stocks in agro-silvo-pastoral environments, different models have been applied worldwide at local or regional scales, such as as RothC (Francaviglia et al., 2012) or CENTURY (Alvaro-Fuentes et al., 2012). However, some of these models may require a high number of input parameters or can underestimate the effect of soil depth. CarboSOIL (Muñoz-Rojas et al., 2013) is an empirical model based on regression techniques and developed to predict SOC contents at standard soil depths (0-25, 25-50 and 50-75 cm) under a range of climate and/or land use change scenarios. CarboSOIL has been successfully applied in different Mediterranean areas ,e.g. Southern Spain (Muñoz-Rojas et al., 2013; Abd-Elmabod et al., 2014), Northern Egypt (Muñoz-Rojas et al., 2014) and Italy (Muñoz-Rojas et al., 2015). In this study, CarboSOIL was applied in the Cardeña and Montoro mountain range Natural Park. This area covers 385 km2 and is located within Sierra Morena (Córdoba, South Spain) and has a semiarid Mediterranean climate. It is characterized by agro-silvo-pastoral systems. The Mediterranean evergreen oak woodland (MEOW-dehesa) is savanna-like open woodland ecosystem characterized by silvopastoral uses, being an ancient human modified Mediterranean landscape (Corral-Fernández et al., 2013; Lozano-García and Parras-Alcántara 2013). The most representative soils in the Cardeña and Montoro mountain range Natural Park are Cambisols, Regosols, Leptosols and Fluvisols. These soils are characterized by low fertility, poor physical conditions and marginal capacity for agricultural use, together with low organic matter (OM) content due to climate conditions (semiarid Mediterranean climate) and soil texture (sandy). The model was applied at different soil depths: 0-25, 25-50 and 50-75 cm (Parras-Alcántara et al., 2015) considering land use and climate changes scenarios based on available global climate models (IPPC, 2007).

    Soils play a key role in the carbon geochemical cycle because they can either emit large quantities of CO2 or on the contrary they can act as a store for carbon. Agriculture and forestry are the only activities that can achieve this effect through photosynthesis and the carbon incorporation into carbohydrates (Parras-Alcántara et al., 2013). The Mediterranean evergreen oak Woodland (MEOW - dehesa) is a type of pasture with scattered evergreen and deciduous oak stands in which cereals are often grown under the tree cover. It is a system dedicated to the combined production of Iberian swine, sheep, fuel wood, coal and cork as well as to hunting. These semi-natural areas still preserve some of the primitive vegetation of the Mediterranean oak forests. The dehesa is a pasture where the herbaceous layer is comprised of either cultivated cereals such as oat, barley and wheat or native vegetation dominated by annual species, which are used as grazing resources. These Iberian open woodland rangelands (dehesas) have been studied from different points of view: hydrologically, with respect to soil organic matter content, as well as in relation to gully erosion, topographical thresholds, soil erosion and runoff production, soil degradation and management practices…etc, among others. The soil organic carbon stock capacity depends not only on abiotic factors such as the mineralogical composition and the climate, but also on soil use and management (Parras et al., 2014 and 2015). In Spanish soils, climate, use and management strongly affect the carbon variability, mainly in soils in dry Mediterranean climates characterized by low organic carbon content, weak structure and readily degradable soils. Hontoria et al. (2004) emphasized that the climate and soil use are two factors that greatly influence carbon content in the Mediterranean climate. This research sought to analyze the SOC stock (SOCS) variability in MEOW - dehesa with cereals, olive grove and Mediterranean oak forest

    Full Text Available The dialogical relation that the Spanish Vanguard settled with tradition —a usual phenomenon also in Latinamerica— has given place to parceled interpretations of the art and literature of the early XXth century, and, specially, of the poetry of the so-called «Generación del 27». During the last two decades, critical approaches has shown that the alliance between the past and «the new» is far from being an obstacle that condemns the Spanish «ismos» to be seen as inauthentic ones, and therefore to be accused of not having the transformative impulse that characterized the artistic projects of the early modernized European countries. Based on the recent works that have reviewed these premises (Soria, Olmedo, Geist, Bosi, García Montero, Wilson..., the purpose of this article is to analyze the well known (and many times cited Rafael Alberti’s poem «Madrigal al billete de tranvía», with the aim to explore, in a creative text, the manifestations of a vanguardist aesthetic that re-elaborated the lyric models inherited from the tradition. In addition to this, this article aims to show that, below the hermeticism of the «neo-Gongorian» madrigal discourse, lies the brief manifesto of a poetics whose decipherment enriches the interpretations of Alberti’s works during the 20s.El diálogo que la vanguardia española entabló con la tradición —fenómeno común también a Latinoamérica— ha dado lugar a interpretaciones parceladas del arte y de la literatura del temprano siglo XX, y muy especialmente, de la poesía de la llamada Generación del 27.

In this study, we developed an optical hyperthermia method capable of inducing in vitro death of glioblastoma cells.Methods: The procedure used was based on irradiation of gold nanorods with a continuous wave laser. This kind of nanoparticle converts absorbed light into localized heat within a short period of time due to the surface plasmon resonance effect. The effectiveness of the method was determined by measuring changes in cell viability after laser irradiation of glioblastoma cells in the presence of gold nanorods.Results: Laser irradiation in the presence of gold nanorods induced a significant decrease in cell viability, while no decrease in cell viability was observed with laser irradiation or incubation with gold nanorods alone. The mechanism of cell death mediated by gold nanorods during photothermal ablation was analyzed, indicating that treatment compromised the integrity of the cell membrane instead of initiating the process of programmed cell death.Conclusion: The use of gold nanorods in hyperthermal therapies is very effective in eliminating glioblastoma cells, and therefore represents an important area of research for therapeutic development.Keywords: laser irradiation, photothermal therapy, surface plasmon resonance, cancer

    Vaccines against rabbit haemorrhagic disease virus (RHDV) are commercially produced in experimentally infected rabbits. A genetically engineered and manufactured version of the major structural protein of RHDV (VP60) is considered to be an alternative approach for vaccine production. Plants have the potential to become an excellent recombinant production system, but the low expression level and insufficient immunogenic potency of plant-derived VP60 still hamper its practical use. In this study, we analysed the expression of a novel multimeric VP60-based antigen in four different plant species, including Nicotiana tabacum L., Solanum tuberosum L., Brassica napus L. and Pisum sativum L. Significant differences were detected in the expression patterns of the novel fusion antigen cholera toxin B subunit (CTB)::VP60 (ctbvp60(SEKDEL)) at the mRNA and protein levels. Pentameric CTB::VP60 molecules were only detected in N. tabacum and P. sativum, and displayed equal levels of CTB, at approximately 0.01% of total soluble protein (TSP), and traces of detectable VP60. However, strong enhancement of the CTB protein content via self-fertilization was only observed in P. sativum, where it reached up to 0.7% of TSP. In rabbits, a strong decrease in the protective vaccine dose required from 48-400 microg potato-derived VP60 [Castanon, S., Marin, M.S., Martin-Alonso, J.M., Boga, J.A., Casais, R., Humara, J.M., Ordas, R.J. and Parra, F.

    Full Text Available The exact names attributed to Ginés Pérez were never at all clear. His first appointment to the Cathedral in Valencia complicated matters even more when he was referred to with the Christian name of what appeared to be "Juan", which only added to the confusion as it lead us to believe that he was the only candidate to apply for that position. Today, however, we now know his true and full names: he was called Ginés Pérez de la Parra. We also know, for the first time, the exact date of his death. The quality of his compositions not only contributed to their popularity but gave rise to the works of other composers being attributed to him. The authorship of the majority of his compositions are considered anonymous, though they can be located in diverse archives. Even so, we cannot find a single copy of the O Crux attributed to his name, despite the numerous copies and their variants that abound in Region of Valencia.El nombre de Ginés Pérez nunca ha tenido la claridad de debía. Su primer nombramiento en la catedral de Valencia ya lo confunde añadiéndole el “Juan” lo que ya siembra confusión, además de sugerirnos que, posiblemente, fue llamado para ocupar el puesto sin oposición.

La valía de sus composiciones motivó, además de la difusión de su obra, la atribución de composiciones de otros autores. La mayor parte de sus composiciones constan como "anónimos", si bien pueden encontrarse en distintos archivos.

To increase the water pressure on the drainage surface, a small reservoir has been constructed, with moveable Taintor sluice gates and with two lateral spillways. The volume of 1 m3/s of additional water is an important increase in the water supply of Madrid, especially taking into account the short time taken to complete this project and its low cost. The water is of very pure quality, owing to the filtration that it undergoes, both along the river bed and at the collecting wells.El objeto del dispositivo que se describe es aprovechar el caudal subálveo de la confluencia de los ríos Lozoya y Jarama, para incorporarlo al abastecimiento de agua a Madrid. La captación se realiza con dos pozos Ranney, con drenes radiales de palastro ranurados longitudinalmente y con una longitud total de unos 500 m para cada pozo. El agua filtrada es impulsada al Canal de La Parra por una tubería de acero electrosoldada con capacidad de 1 m3/s. Para aumentar la carga de agua sobre los drenes se ha construido un azud con dos vanos móviles provistos de compuertas Taintor, y dos aliviaderos laterales. El rendimiento obtenido de 1 m3/s constituye una importante mejora en el abastecimiento de aguas a la capital, habida cuenta del reducido plazo de ejecución y la economía de esta obra. El agua obtenida resulta de inmejorables condiciones a causa del filtrado a que se encuentra sometida, tanto por los acarreos del río como por los drenes de captación.

    Full Text Available The Rosso Ammonitico of the Montagna Grande area is very interesting because of the great diversification in facies and thickness in three very closely situated sections. The Jurassic succession in this area is that typical of the Trapanese Domain. It starts with a thick pile of platform limestones (Inici Formation: Hettangian - Sinemurian that are overlain by typically condensed and commonly nodular pelagic limestones (Rosso Ammonitico: Middle Jurassic - lowermost Cretaceous. The good exposure of this succession in active quarries allows observation of sedimentological and palaeontological details and to improve the understanding of the Jurassic tectono-sedimentary evolution. The Rocca chi Parra quarry shows a stepped surface, with a relief of some metres, incised in the Inici Formation. It is covered by lenticular or wedge-shaped lithosomes a few metres-thick of highly condensed Rosso Ammonitico. It is interpreted as a slide scar along which a thin but extensive block of lithified platform limestones was detached and slid downslope. The Poggio Roccione quarry shows neptunian sills and collapse structures in the middle part of the Rosso Ammonitico that on the whole is thicker (about 12 m than at Rocca chi Parra. They indicate sea-floor instability probably due to seismic shocks with brittle to plastic behaviour of sediments depending on their coherence. The Montagna Grande outcrop shows an even thicker succession which includes a wedge of cherty limestones about 10 m thick intercalated between a lower and an upper Rosso Ammonitico calcareous unit. The features described in these three sections document a highly irregular sea-floor topography which in turn was controlled by several phases of extensional tectonics during Mid and Late Jurassic pelagic sedimentation. Structurally higher sectors closer to fault scarps were affected by a very condensed sedimentation, the opening of subvertical dykes and the triggering of large slides. Structurally

    Full Text Available Egg laying site selection by a host plant specialist leaf miner moth at two intra-plant levels in the northern Chilean Atacama Desert. The spatial distribution of the immature stages of the leaf miner Angelabella tecomae Vargas & Parra, 2005 was determined at two intra-plant levels (shoot and leaflet on the shrub Tecoma fulva fulva (Cav. D. Don (Bignoniaceae in the Azapa valley, northern Chilean Atacama Desert. An aggregated spatial pattern was detected for all the immature stages along the shoot, with an age dependent relative position: eggs and first instar larvae were clumped at apex; second, third and fourth instar larvae were mostly found at intermediate positions; meanwhile the spinning larva and pupa were clumped at basis. This pattern suggests that the females select new, actively growing leaflets for egg laying. At the leaflet level, the immature stages were found more frequently at underside. Furthermore, survivorship was higher for larvae from underside mines. All these results highlight the importance of an accurate selection of egg laying site in the life history of this highly specialized leaf miner. By contrast, eventual wrong choices in the egg laying site selection may be associated with diminished larval survivorship. The importance of the continuous availability of new plant tissue in this highly human modified arid environment is discussed in relation with the observed patterns.

  18. Representations of Eros: From Modernismo to Posmodernismo

    Alicia Rita Rueda-Acedo

    2014-12-01

    Full Text Available In this paper I explore eroticism as a key element in the evolution from modernismo to posmodernismo. If eroticism is a crucial component to understand the binary concept of the world and the universe present in modernist poetry, postmodernist poets distance themselves from this outlook towards a “critic system”. In order to explore this shift, I analyze the works of postmodernist poets such as Baldomero Fernández Moreno, Ramón López Velarde and Regino E. Boti, and vanguardist poet Nicanor Parra, comparing their writing to Rubén Darío’s. I emphasize the evolution from Darío’s conception of the universe where women play an integral role to Parra’s conception of the woman as a viper and how this change is related to a substantial change of the conception of poetry. I also study eroticism in the work of Alfonsina Storni, Delmira Agustini and Gabriela Mistral as an instrument to critic and review the patriarchal cannon imposed by modernism. These poets eliminate the connection between eroticism and beauty, and they claim eroticism as a differentiating tool in their feminist writing and agenda. Sex and eroticism are elements that define and differentiate modernism from postmodernism, and can be considered as a crucial turning point for this shift.

    Full Text Available Mesophotic coral ecosystems (MCEs; reefs 30-150m depth are of increased research interest because of their potential role as depth refuges from many shallow reef threats. Yet few studies have identified patterns in fish species composition and trophic group structure between MCEs and their shallow counterparts. Here we explore reef fish species and biomass distributions across shallow to upper-MCE Caribbean reef gradients (5-40m around Utila, Honduras, using a diver-operated stereo-video system. Broadly, we found reef fish species richness, abundance and biomass declining with depth. At the trophic group level we identified declines in herbivores (both total and relative community biomass with depth, mostly driven by declines in parrotfish (Scaridae. Piscivores increased as a proportion of the community with increased depth while, in contrast to previous studies, we found no change in relative planktivorous reef fish biomass across the depth gradient. In addition, we also found evidence of ontogenetic migrations in the blue tang (Acanthurus coeruleus, striped parrotfish (Scarus iserti, blue chromis (Chromis cyanea, creole wrasse (Clepticus parrae, bluehead wrasse (Thalassoma bifasciatum and yellowtail snapper (Ocyurus chrysurus, with a higher proportion of larger individuals at mesophotic and near-mesophotic depths than on shallow reefs. Our results highlight the importance of using biomass measures when considering fish community changes across depth gradients, with biomass generating different results to simple abundance counts.

    Brain computer interface applications, developed for both healthy and clinical populations, critically depend on decoding brain activity in single trials. The goal of the present study was to detect distinctive spatiotemporal brain patterns within a set of event related responses. We introduce a novel classification algorithm, the spatially weighted FLD-PCA (SWFP), which is based on a two-step linear classification of event-related responses, using fisher linear discriminant (FLD) classifier and principal component analysis (PCA) for dimensionality reduction. As a benchmark algorithm, we consider the hierarchical discriminant component Analysis (HDCA), introduced by Parra, et al. 2007. We also consider a modified version of the HDCA, namely the hierarchical discriminant principal component analysis algorithm (HDPCA). We compare single-trial classification accuracies of all the three algorithms, each applied to detect target images within a rapid serial visual presentation (RSVP, 10 Hz) of images from five different object categories, based on single-trial brain responses. We find a systematic superiority of our classification algorithm in the tested paradigm. Additionally, HDPCA significantly increases classification accuracies compared to the HDCA. Finally, we show that presenting several repetitions of the same image exemplars improve accuracy, and thus may be important in cases where high accuracy is crucial.

    Different approaches of soil sampling can provide significantly different estimates of soil organic carbon stocks (SOCs) (Parras-Alcántara et al., 2015a). Many studies have focused on SOC distribution only in the biologically active layers of topsoil, the IPCC carbon accounting method estimates the change in SOC storage for the top 30 cm of a soil profile, and indeed limited data are available for SOCs below this depth. Moreover, SOC estimates are more uncertain in areas with heterogeneous land uses and pedoclimatic conditions such as Mediterranean environments, which are more prone to land degradation due to SOC degradation and depletion and erosive processes (Muñoz-Rojas et al., 2015). Anyhow, the open question is whether soil should be sampled following the pedogenetic horizons with soil entire soil approach (ESP), or along fixed depth increments using the soil control section method (SCS) (Parras-Alcántara et al., 2015b). In addition, SOCs are often not adjusted for the soil volume occupied by coarse fragments as recommended by the IPCC Good Practice Guidance for LULUCF (IPCC, 2003) accordingly to the equation: SOCs = SOC (g kg-1) × bulk density (Mg m-3) × depth (m) × (1 - coarse fragment) × 10. The work deals with the comparison of SOCs using the ESP and SCS approaches, applied to a study area of northeastern Sardinia (Italy) under typical agro-silvo-pastoral systems (Francaviglia et al., 2014). The area lies within a hilly basin where elevation is in the range 275-340 m a.s.l., and slope ranges from 2-6% to 16-30%. The local climate is warm temperate with dry and hot summers, mean annual rainfall is 623 mm (range 367-811mm) and mean annual temperature is 15.0° C (13.8-16.4° C). The area has the same soil type (Haplic Endoleptic Cambisols, Dystric) according to IUSS Working Group WRB (2006), and the following land uses with different levels of cropping intensification were compared: Tilled vineyards (Tv), No-tilled grassed vineyards (Ntgv), Hay crop

In both methods of producing maps, increases of probable number of coffee leaf miner cycles were observed in the future. Although, using fixed increases in the average temperature caused a substimation of the number of cycles in the future, comparing to adopting increases of temperatures varying spatially. Besides the sazonal differences, regional differents were observed to the number of cycles of the leaf miner coffee.

    Ideal magnetohydrodynamic (MHD) instabilities such as the kink [1] and torus [2] instabilities are believed to play an important role in driving "storage-and-release" eruptions in the solar corona. These instabilities act on long-lived, arched magnetic flux ropes that are "line-tied" to the solar surface. In spite of numerous observational and computational studies, the conditions under which these instabilities produce an eruption remain a subject of intense debate. In this paper, we use a line-tied, arched flux rope experiment to study storage-and-release eruptions in the laboratory [3]. An in situ array of miniature magnetic probes is used to assess the equilibrium and stability of the laboratory flux ropes. Two major results are reported here: First, a new stability regime is identified where torus-unstable flux ropes fail to erupt. In this "failed torus" regime, the flux rope is torus-unstable but kink-stable. Under these conditions, a dynamic "toroidal field tension force" surges in magnitude and causes the flux rope to contract. This tension force, which is missing from existing eruption models, is the J×B force between self-generated poloidal currents in the flux rope and the toroidal (guide) component of the vacuum field. Secondly, a clear torus instability threshold is observed in the kink-unstable regime. This latter result, which is consistent with existing theoretical [4] and numerical [5] findings, verifies the key role of the torus instability in driving some solar eruptions.

Within the last 50 years, the surface occupied by olive groves has progressively increased in Spain including more complex topographies, with steeper slopes and higher altitudes. This situation has caused serious erosion problems; there is a huge range of studies assessing possible solutions to this problem and new tillage and management techniques have been developed (Lozano-García and Parras-Alcántara, 2013). However, topography has influence in soil properties too. The impact of the topographical position on soil properties, including soil organic carbon (SOC) and Nitrogen (N) stocks, and soil quality (expressed as Stratification Ratios-SRs) was evaluated in a Mediterranean olive grove with traditional tillage. MATERIAL AND METHODS The study was carried out in a rain-fed olive grove in Jaén managed with traditional tillage (with disc harrow 25 cm) and receiving mineral fertilization. Three topographical positions with the same aspect: summit, backslope and toeslope were chosen for evaluation. The soil samples were taken from four soil sections of 0.25 m (0-1 m) in order to establish a good comparison. Soil properties determined were: soil particle size, SOC and total Nitrogen (N). SOC and N stock, expressed for a specific depth in Mg ha-1. Stratification ratios (that can be used as an indicator of dynamic soil quality) for SOC and N at three different depths were calculated. The effect of topographical position on SOC and N stocks and other soil properties was analyzed using a ANOVA, followed by a Tuckey test. RESULTS SOC decreased with depth, in addition, the SOC and N content increased along the downslope direction (5.5, 6.5 and 7.1 g C kg-1; and 0.3, 0.8 and 0.9 g N kg-1 in the surface layer in the summit, backslope and toeslope respectively) as well as SOC stock considering the two first soil sections. The N stock varied significantly along the topographical

    Full Text Available The leaf area index (LAI of a vineyard (Vitis vinifera L. cv. Cabernet Sauvignon located in the commune of Cauquenes, Maule Region in Chile, was estimated from digital images obtained with a commercial camera using two indirect methods: Leaf Area Gap and Brightness (LAGB and -Photogrammetric Leaf Area Quantification System (PLAQS. The latter requires deleafing of the grapevine. In a normalized difference vegetation index (NDVI map, three points of vine vigor were selected: high, medium, and low for which horizontal and vertical images were obtained. Images were filtered with the Arc View GIS 3.1 program to provide only leaf images and corresponding pixel numbers. Image area and square meters per linear meter were calculated. The best models were selected from  three linear regression adjustments: i LAI of LAGB vertical images of with LAI of PLAQS, ii LAI of PLAQS horizontal images with and, iii LAI of both types of images with PLAQS. The parameters in all models were significant. Adjustment between the LAGB and PLAQS vertical images provides greater simplicity and easy calculation since it requires only a vertical image to estimate LAI. Images thus obtained can accurately estimate LAI in this type of cultivar.En un viñedo (Vitis vinifera L. cv.

    Anderson-Darling test at each horizon or a combination of horizons for each soil type. RESULTS The LUC had a negative impact in the soil, reducing the SOC and TN stocks. The conversion from AC to V and OG involved the loss of the SOC stock (52.7% and 64.9% to V and OG respectively) and the loss of the TN stock (42.6% and 38.1% to V and OG respectively). The reduction of SOC by LUC, can be explained by a degraded process (due to vegetation losses and unsustainable soil management, which result in progressive impoverishment in the soil organic matter (OM) content, causing low productivity, which derived in unsuitable chemical properties) and by the reduced input of OM in cultivated soils, which reduced physical protection of soil and increased water erosion. However, 46 years of LUC had a positive effect in the soil, increasing the SR (in V and OG) of SOC, TN and C:N ratio (Parras-Alcántara et al., 2013).

Aunque se reconocen como degradadores de restos orgánicos, otros datos sugieren una participación más activa en procesos comunitarios, pero la información disponible es escasa. Con objeto de determinar los taxa de insectos presentes en el litoral de Concepción, sur de Chile (ca. 36°40' S, y su importancia ecológica potencial en el sistema, realizamos un estudio exploratorio en cuatro localidades: Caleta Tumbes, Cocholgüe, área norte de la desembocadura del río Bío-Bío y Punta de Parra. En cada localidad evaluamos la diversidad de insectos en la zona intermareal baja, media y alta, registrando el hábitat o tipo de substrato al que se encontraban asociados. Detectamos 24 taxa de insectos distribuidos en cuatro órdenes y 18 familias, incluyendo especies nativas e introducidas, parte de ellas ocasionales o casuales. La diversidad fue mayor en la zona intermareal media, particularmente en el intermareal rocoso donde hay mayor abundancia de algas. Además detectamos asociaciones recurrentes entre insectos y las especies de algas intermareales más comunes (in situ o varadas, vivas o en descomposición, usadas aparentemente como alimento o hábitat, sugiriendo un papel fundamental en el reciclamiento e intercambio de nutrientes entre el intermareal y el submareal.

    determined were: soil particle size, bulk density, SOC, TN, C:N ratio, stocks and SR. The statistical significance of the differences in the variables between management practices was tested using the Anderson-Darling test at each horizon or a combination of horizons for each soil type. RESULTS The SOC-S was greater in CM (75.64 Mg ha-1) than in LP (44.01 Mg ha-1). SOC-S was very similar in OF and CT (CM [74.90 Mg ha-1-CT; 76.39 Mg ha-1-OF] and LP [44.77 Mg ha-1-CT; 43.25 Mg ha-1-OF]). Data analysis showed that management practices had little effect on SOC storage. Significant differences between soil types and management practices were found in SOC content for different horizons. The SR index was >2 in both soils types (CM and LP) and management systems (OF and CT). These results indicate that the soil is of high quality and that management practices have little influence on SOC-S (Parras-Alcántara et al., 2014) and do not affect SOC storage.

In addition, both oil mill wastes contributed to delay runoff generation and erosion, enhancing the infiltration of rainwater. Furthermore, application of the wastes improved soil quality (SRs of SOC were greater than 2). So the addition of these oil mill wastes to agricultural soils has become a viable solution to their disposal; not only do they enrich deficient soils with organic matter, but also improve their physical and chemical properties, even decrease soil erosion, especially olive leaves.

  19. Impact of heterogeneous activity and community structure on the evolutionary success of cooperators in social networks.

    Recent empirical studies suggest that heavy-tailed distributions of human activities are universal in real social dynamics [L. Muchnik, S. Pei, L. C. Parra, S. D. S. Reis, J. S. Andrade Jr., S. Havlin, and H. A. Makse, Sci. Rep. 3, 1783 (2013)]. On the other hand, community structure is ubiquitous in biological and social networks [M. E. J. Newman, Nat. Phys. 8, 25 (2012)]. Motivated by these facts, we here consider the evolutionary prisoner's dilemma game taking place on top of a real social network to investigate how the community structure and the heterogeneity in activity of individuals affect the evolution of cooperation. In particular, we account for a variation of the birth-death process (which can also be regarded as a proportional imitation rule from a social point of view) for the strategy updating under both weak and strong selection (meaning the payoffs harvested from games contribute either slightly or heavily to the individuals' performance). By implementing comparative studies, where the players are selected either randomly or in terms of their actual activities to play games with their immediate neighbors, we figure out that heterogeneous activity benefits the emergence of collective cooperation in a harsh environment (the action for cooperation is costly) under strong selection, whereas it impairs the formation of altruism under weak selection. Moreover, we find that the abundance of communities in the social network can evidently foster the formation of cooperation under strong selection, in contrast to the games evolving on randomized counterparts. Our results are therefore helpful for us to better understand the evolution of cooperation in real social systems.

    We explore, numerically, the evolution of localisation due to plastic collapse in both coaxial shortening and simple shearing deformations. These localisation features arise from plastic behaviour and hence differ from the formation of anticracks modelled by linear elastic behaviour (Fletcher and Pollard, 1990). The behaviour is close to that discussed by Rudnicki (2004) and Chemenda (2009) in that localisation consists of zones of plastic collapse separated by elastically unloaded regions. The constitutive behaviour assumed here comprises a Tresca yield with both strain-softening of the yield stress and of a cap that models plastic volumetric collapse during phase transformations, such as the olivine-spinel transition, with ΔVI., 2009.

  2. A very general electromagnetic gyrokinetic formalism

    McMillan, B. F.; Sharma, A.

    2016-09-01

    We derive a gyrokinetic formalism which is very generally valid: the ordering allows both large inhomogeneities in plasma flow and magnetic field at long wavelength, such as typical drift-kinetic theories, as well as fluctuations at the gyro-scale. The underlying approach is to order the vorticity to be small, and to assert that the timescales in the local plasma frame are long compared to the gyrofrequency. Unlike most other derivations, we do not treat the long and short wavelength components of the fluctuating fields separately; the single-field description defines the particle motion and their interaction with the electromagnetic field at small-scale, the system-scale, and intermediate length scales in a unified fashion. As in earlier literature, the work consists of identifying a coordinate system where the gyroangle-dependent terms are small, and using a near-unity transform to systematically find a set of coordinates where the gyroangle dependence vanishes. We derive a gyrokinetic Lagrangian which is valid where the vorticity | ∇ × ( E × B / B ) | is small compared to the gyrofrequency Ω, and the magnetic field scale length is long compared to the gyroradius; we also require that time variation be slow in an appropriately chosen reference frame. This appears to be a minimum set of constraints on a gyrokinetic theory and is substantially more general than earlier approaches. It is the general-geometry electromagnetic extension of Dimits, Phys. Plasmas 17, 055901 (2010) (which is an electrostatic formalism with a homogeneous background magnetic field). This approach also does not require a separate treatment of fluctuating and background components of the magnetic field, unlike much of the previous literature. As a consequence, the "cross terms" due to a combination of long- and short-wavelength variation, which were ignored in the earlier work (but derived in a more restrictive ordering in Parra and Calvo, Plasma Phys.

  4. Timing and Style of Deformation in the Floresta Massif, Axial Eastern Cordillera, Colombia

    Saylor, J.; Stockli, D. F.; Mora, A.

    2009-12-01

    The Floresta Massif is one of the largest exposures of Paleozoic and Pre-Cambrian rocks in the Eastern Cordillera. Estimates for the age of onset of shortening-related deformation in the Eastern Cordillera range from late Cretaceous to late Miocene (e.g., Hoorn et al., 1995; Bayona et al., 2008; Parra et al., 2009). The massif is typically interpreted as being exhumed along a high-angle reverse fault (the Soapaga fault) that reactivated Mesozoic extensional structures (e.g., Kammer and Sanchez, 2006). We examined these dual linked issued with new zircon U/Th-He (ZHe) data, new geological mapping and previously published apatite fission track (AFT) data from the Floresta Massif and the associated footwall strata. Previously, an overturned Paleozoic - Cretaceous sequence was mapped emplaced on Tertiary strata along the Soapaga fault. However, new geologic mapping identifies two previously unrecognized thrusts which place, from west to east, Paleozoic strata on Jurassic strata (Fault 3), Jurassic strata on Cretaceous strata (Fault 2) and Cretaceous strata on Tertiary strata (along the previously identified Fault 1). These results are confirmed by AFT and ZHe data. ZHe ages show no resetting in the Tertiary footwall strata, but show partial resetting in the Cretaceous strata and full resetting in the Jurassic and Paleozoic strata. Similarly, AFT data show older ages in the Cretaceous strata than in the Jurassic or Paleozoic strata. Fully reset ZHe ages from Jurassic strata show that exhumation of the Floresta Massif was ongoing by at least the early Oligocene (~ 30 Ma). However, this deformation post-dates an older episode of deformation associated with partially reset ZHe ages in the Cretaceous strata. Based on a decrease in lag time in detrital ZHe data, we infer that the earlier episode of deformation occurred in the mid - late Eocene (45 - 35 Ma).

In the present study, we show that bozepinib also has antitumor activity in colon cancer cells, showing 50% inhibitory concentration (IC50 values lower than those described for breast cancer cells and suggesting great potential of this synthetic drug in the treatment of cancer. We identified that the double-stranded RNA-dependent protein kinase (PKR is a target of bozepinib, being upregulated and activated by the drug. However, p53 was not affected by bozepinib, and was not necessary for induction of apoptosis in either breast or colon cancer cells. In addition, the efficacy of bozepinib was improved when combined with the interferon-alpha (IFNα cytokine, which enhanced bozepinib-induced apoptosis with involvement of protein kinase PKR. Moreover, we report here, for the first time, that in combined therapy, IFNα induces a clear process of autophagosome formation, and prior treatment with chloroquine, an autophagy inhibitor, is able to

This study capitalized on the mechanisms suppressing vacuolar H(+)-ATPase (V-ATPase) in pfk2Δ to gain new knowledge of the mechanisms underlying glucose-dependent V-ATPase regulation. Because V-ATPase is fully assembled in pfk2Δ, and glycolysis partially suppressed at steady state, we manipulated glycolysis and assessed its direct involvement on V-ATPase function. At steady state, the ratio of proton transport to ATP hydrolysis increased 24% after increasing the glucose concentration from 2% to 4% to enhance the glycolysis flow in pfk2Δ. Tighter coupling restored vacuolar pH when glucose was abundant and glycolysis operated below capacity. After readdition of glucose to glucose-deprived cells, glucose-dependent V1Vo reassembly was proportional to the glycolysis flow. Readdition of 2% glucose to pfk2Δ cells, which restored 62% of ethanol concentration, led to equivalent 60% V1Vo reassembly levels. Steady-state level of assembly (100% reassembly) was reached at 4% glucose when glycolysis reached a threshold in pfk2Δ (≥40% the wild-type flow). At 4% glucose, the level of Pfk1p co-immunoprecipitated with V-ATPase decreased 58% in pfk2Δ, suggesting that Pfk1p binding to V-ATPase may be inhibitory in the mutant. We concluded that V-ATPase activity at steady state and V-ATPase reassembly after readdition of glucose to glucose-deprived cells are controlled by the glycolysis flow. We propose a new mechanism by which glucose regulates V-ATPase catalytic activity that occurs at steady state without changing V1Vo assembly.

    Full Text Available Introducción: En Colombia, las enfermeras cuentan con el código deontológico, creado por la Ley 911 del 2004, el cual define las disposiciones legales sobre ética para el ejercicio de la enfermería y conceptualiza el acto de cuidado. Materiales y Métodos: Estudio de corte transversal, en enfermeras de instituciones públicas y privadas de la ciudad de Bucaramanga y su área metropolitana. Se diseñó un instrumento de 19 ítems. Se realizó análisis descriptivo. Resultados: 251 enfermeras fueron analizadas, mediana de edad 31 años; 87.6% mujeres; 27.0% tenían formación de posgrado; experiencia laboral mediana de 6 años. La mayoría refirieron que siempre aplicaban lo establecido en los Capítulos I y II, pero, no ocurrió así para el caso del ítem: “Cuando existen normas institucionales que limitan el acceso a los servicios de salud usted aboga por los pacientes”. En relación al Capítulo II del Título II, los aspectos de infraestructura, procedimientos técnicos administrativos, objeción de conciencia y la distribución del cuidado de acuerdo a la complejidad del paciente, se cumple a veces. Discusión: Los hallazgos de este estudio son similares con otros estudios, especialmente lo relacionado con los principios éticos definidos en el título I. Conclusiones: Los resultados, revelan que las enfermeras perciben que un porcentaje significativo de lo dispuesto en estos títulos se cumple a veces, lo cual sugiere un mayor análisis de estos aspectos.

The formulations were stabilized with poloxamer 188 (1.66% and 3.5% and submitted individually for freeze-drying and γ-irradiation with polyethylene glycol 3350 (PEG3350 and d-(+-trehalose (TRE. Both formulations satisfied criteria according to all physicochemical parameters required for ocular pharmaceuticals. The FB-PεCL-NP formulations showed non-Newtonian behavior and sustained drug release. Ex vivo permeation analysis using isolated ocular pig tissues suggested that the presence of PEG3350 results in a reduction of FB transcorneal permeation. Moreover, TRE improved the penetration of FB across the cornea, especially after γ-irradiation. In addition, both formulations did not show a significant affinity in increasing FB transscleral permeation. Both formulations were classified as nonirritating, safe products for ophthalmic administration according to hen’s egg test-chorioallantoic membrane and Draize eye test. Furthermore, an in vivo anti-inflammatory efficacy test showed that irradiated FB-PεCL-NPs prepared with PEG3350 (IR-NPsPEG have longer anti-inflammatory effects than those presented with irradiated FB-PεCL-NPs prepared with TRE (IR-NPsTRE. IR-NPsPEG showed a suitable physical stability after an aqueous reconstitution over .30 days.

    Background: Personal care products are a source of exposure to potentially endocrine-disrupting chemicals such as phthalates, parabens, triclosan, and benzophenone-3 (BP-3) for adolescent girls. Methods: We enrolled 100 Latina girls in a youth-led, community-based participatory research intervention study to determine whether using personal care products whose labels stated they did not contain these chemicals for 3 days could lower urinary concentrations. Pre- and postintervention urine samples were analyzed for phthalate metabolites, parabens, triclosan, and BP-3 using high-performance liquid chromatography/tandem mass spectrometry. Results: Urinary concentrations of mono-ethyl phthalate (MEP) decreased by 27.4% (95% CI: –39.3, –13.2) on average over the 3-day intervention; no significant changes were seen in urinary concentrations of mono-n-butyl phthalate (MnBP) and mono-isobutyl phthalate (MiBP). Methyl and propyl paraben concentrations decreased by 43.9% (95% CI: –61.3, –18.8) and 45.4% (95% CI: –63.7, –17.9), respectively. Unexpectedly, concentrations of ethyl and butyl paraben concentrations increased, although concentrations were low overall and not detected in almost half the samples. Triclosan concentrations decreased by 35.7% (95% CI: –53.3, –11.6), and BP-3 concentrations decreased by 36.0% (95% CI: –51.0, –16.4). Discussion: This study demonstrates that techniques available to consumers, such as choosing personal care products that are labeled to be free of phthalates, parabens, triclosan, and BP-3, can reduce personal exposure to possible endocrine-disrupting chemicals. Involving youth in the design and implementation of the study was key to recruitment, retention, compliance, and acceptability of the intervention.

    -2005, financiado por la CE, ha tratado el problema de la combadura de determinados tipos de mármol observado en fachadas situadas tanto en climas cálidos como en climas fríos. Los principales objetivos del proyecto TEAM eran los de conocer y explicar los mecanismos de la dilatación, la combadura y la pérdida de resistencia que provocaban la degradación de las fachadas revestidas de mármol y caliza, así como prevenir el uso de mármol y caliza inadecuados mediante la presentación de borradores de nuevas normas europeas. La inspección de aproximadamente 200 edificios ofreció una idea clara del alcance del problema en términos geográficos, geológicos y climáticos. El estudio detallado de 6 edificios dio como resultado una metodología para la evaluación de fachadas que incluía un sistema de seguimiento y la evaluación de riesgos. Se investigaron tanto en el laboratorio como sobre el terreno casi 100 tipos distintos de piedra procedentes de diferentes países y utilizados en distintos climas, lo que permitió explicar los mecanismos de degradación y los factores que más influyen en ella. Se prepararon dos métodos de ensayo con sus correspondientes declaraciones de precisión parra enviar al CEN TC 246: uno sobre la combadura y otro sobre la dilatación térmica irreversible en condiciones húmedas.

    2000-03-31

    The Carbon Dioxide Information Analysis Center (CDIAC), which includes the World Data Center (WDC) for Atmospheric Trace Gases, is the primary global-change data and information analysis center of the Department of Energy (DOE). More than just an archive of data sets and publications, CDIAC has--since its inception in 1982--enhanced the value of its holdings through intensive quality assurance, documentation, and integration. Whereas many traditional data centers are discipline-based (for example, meteorology or oceanography), CDIAC's scope includes potentially anything and everything that would be of value to users concerned with the greenhouse effect and global climate change, including concentrations of carbon dioxide (CO{sub 2}) and other radiatively active gases in the atmosphere; the role of the terrestrial biosphere and the oceans in the biogeochemical cycles of greenhouse gases; emissions of CO{sub 2} and other trace gases to the atmosphere; long-term climate trends; the effects of elevated CO{sub 2} on vegetation; and the vulnerability of coastal areas to rising sea level. CDIAC is located within the Environmental Sciences Division (ESD) at Oak Ridge National Laboratory (ORNL) in Oak Ridge, Tennessee. CDIAC is co-located with ESD researchers investigating global-change topics, such as the global carbon cycle and the effects of carbon dioxide on vegetation. CDIAC staff are also connected with current ORNL research on related topics, such as renewable energy and supercomputing technologies. CDIAC is supported by the Environmental Sciences Division (Jerry Elwood, Acting Director) of DOE's Office of Biological and Environmental Research. CDIAC's FY 1999 budget was 2.2M dollars. CDIAC represents the DOE in the multi-agency Global Change Data and Information System. Bobbi Parra, and Wanda Ferrell on an interim basis, is DOE's Program Manager with responsibility for CDIAC. CDIAC comprises three groups, Global Change Data, Computer Systems, and

    The Agua Nueva Formation in the vicinity of Xilitla, State of San Luis Potosí, Central Mexico, consists of interbedded brown shale (Grayish orange 10YR 7/4 to Moderate yellowish brown 10YR 5/4) and dark-gray fossiliferous limestone (Bluish gray 5B 6/1 to Dark bluish gray 5B 4/1), varying between 10 and 20 cm in thickness. The sequence also includes 2 to 4 cm- thick intermittent bentonite layers (Moderate greenish yellow 10Y 7/4, to dark greenish yellow 10Y 6/6 and Light olive 10Y 5/4). At the field scale, shaly intervals show no apparent internal structures, whereas most limestone beds show primary lamination at the millimeter scale (1-2 mm), and intermittent layers of black chert of about 5 cm thick. Pyrite is present as disseminated crystals and as 2 cm-thick layers. Bioturbation or macrobenthic organisms other than inoceramids do not occur in the Agua Nueva Formation at Xilitla. Unusual macrofossils are present only in limestone strata, and consist of well- preserved diverse genera of fishes such as sharks, Ptychodus sp. and teleosteans, Rhynchodercetis sp., Tselfatia sp., Goulmimichthys sp., and scales of Ichtyodectiformes, as well as ammonites and inoceramids (Blanco et al., 2006). The presence of Inoceramus (Mytyloides) labiatus (Maldonado-Koederll, 1956) indicates an Early Turonian age for the sequence. Total carbonate content (CaCO3 = TIC) varies between 62 and 94% in the Limestone beds, which yield Total Organic Carbon (TOC) from 0.4% to 2.5%; the shale intervals contain TIC values consistently lower than 33% and TOC lower than 0.8% Microscopically the limestone beds vary from mudstone to packstone composed essentially of coccoid cyanobacteria similar to coeval deposits in northeastern Mexico, Coahuila State, at Parras de La Fuente (Duque- Botero 2006). Similarly, the microspheroids are spherical to sub-spherical, and occur as isolated elements or aggregates forming series of chains of parallel-packed light lamina 1-2 mm thick.

Association of Brucella Meningoencephalitis with Cerebrospinal Fluid Shunt in a Child: a Case Report. Iran J Child Neurol. 2013 Winter:7(1:35-38. Brucellosis is an endemic zoonosis in Iran. It is a systemic infection that can involve any organs or systems of the body and have variable presentations. Ventriculoperitoneal (VP shunt infections due to brucellosis have been rarely reported in the literatures.This  is  the  history  of  a  four  years  old  boy  who  developed  Brucella meningoencephalitis at the age of 42 months, whilst he had a VP shunt in situ for hydrocephalus treatment. Also, he presented brucellosis as acute abdomen. This patient was treated with trimethoprim-sulfamethoxazole, gentamicin and rifampicin. The shunt was extracted and all clinical and laboratory test abnormalities subsided through this management.We propose that in a patient with Brucella meningoencephalitis, the cerebrospinal  fluid shunt  system  can  be  extracted  and  treatment  with appropriate combination of antibiotics could be successful. Moreover, it shows that brucellosis should be considered in the differential diagnosis for acute abdomen and ascites in endemic regions.References1.

    depletion times accelerating by a factor of 3 to 5 between now and 2050. For these reasons, we do question fuelwood as a sustainable future energy source in Africa. This study is based on simple models, and we must acknowledge that these initial results are most likely negatively biased for several reasons. With the main results we will discuss the possible shortcomings and relate our results to some studies with more positive assessments of the fuelwood sustainability.

    Northeast Mexico is essentially the juncture of two distinctly different tectono-stratigraphic provinces, the eastern Gulf of Mexico (Coastal Plane, Sierra Madre Oriental) province and the western Pacific Mexico (Rivera plate, Meso-American trench, Sierra Madre Occidental) province (Goldhammer & Johnson, 2001). Tectonic evolution in northeast Mexico is dominated by divergent-margin development associated with the opening of the Gulf of Mexico and overprinted by non-igneous Laramide orogenic effects (Pindell et al., 1988). The structural grain of northeast Mexico consists of Triassic to Liassic fault-controlled basement blocks, the development of which reflects in part late Paleozoic orogenic patterns of metamorphism and igneous intrusion (Wilson, 1990). There are different tectonic provinces which are recognized interpreting the basement and sediment cover of this area: Coahuila block, La Popa sub-basin, Sabinas basin, Burgos basin, Sierra Madre Oriental (Monterrey trough), and Parras basin. Mojave-Sonora megashear and San Marcos fault (Chavez-Cabello et al., 2007) are two principal fault zones crossing the northeast Mexico in NW-SE direction. This paper is presented the integral analysis of the gravity and magnetic data in the northeast Mexico. Complementing with a Digital Model of Elevations (DME) that combined with the review of previous geological studies it serves to compare the surface structures and blocks of basement in this area. Also the separation of the most important tectonic blocks was done, and 2.5D geological-geophysical model was finally developed. This model represents in a general way the principal structural characteristics of northeast Mexico. Gravity and magnetic data analysis was used with purpose to study the structure of the substrata in order to allow modeling of the basement structure and its relation with the sedimentary cover features. The Bouguer gravity and the total field aeromagnetic data were supplied by Geological Survey of Mexico

  5. Integrated geographic information systems (IGIS) analysis and definition of the tectonic framework of northern Mexico

    Martinez Pina, Carlos Manuel

    Crustal rupture structures reactivated in the course of the tectonic history of northern Mexico are the surface expressions of planes of weakness, in the form of simple or composite rectilinear features or slightly curved, defined as lineaments. Unless otherwise defined as strike-slip faults, lineaments are part of parallel and sub-parallel oblique convergent or oblique divergent tectonic zones cross cutting the Sierra Madre Occidental and northern Mexico, in a NW trend. These shear zones are the response to the oblique subduction of the Farallon plate beneath North America. Kinematic analysis of five selected sites in northern Mexico, three basins and two compressional shear zones, proved possible a combination of shear mechanism diagram and models from analogue materials, with satellite imagery and geographic information systems, as an aid to define strike-slip fault motion. This was done using a reverse engineering process by comparing geometries. One of the sites assessed, involving the Parras Basin, Coahuila Block (CB), San Marcos fault, a postulated PBF-1 fault, allowed for palinpastic reconstruction of the CB that corroborated the results of the vector motion defined, in addition to an extension of ˜25% in a northwest southeast direction. A GIS-based compilation and georeferenced regional structural studies by several researchers were used as ground control areas (GCA); their interpolation and interpretation, resulted in a tectonic framework map of northern Mexico. In addition, shaded relief models overlaid by the lineaments / fault layer allowed structural analyses of basins related to these major structures. Two important results were obtained from this study: the Tepehuanes-San Luis-fault (TSL) and the Guadalupe fault, named herein, displaces the Villa de Reyes graben, and the Aguascalientes graben, respectively, to the SE, confirming their left lateral vector motion; afterwards TSL was displaced south by the right lateral strike slip Taxco-San Miguel de

En cuanto a lo digital, presentamos un balance de los procesos de recepción de una serie de documentales etnográficos realizados con las comunidades para la transformación de la realidad social en un modelo que hemos venido en llamar etnografías de empoderamiento (Martínez y Camas, 2014, Camas y Martínez 2015; Trueba y Delgado, 1991. Esta forma de realización de documentales etnográficos desde la investigación participativa (Pereda y De Prada, 2014 nos ha ido permitiendo constituir comunidades de aprendizaje (Elboj, 2002 y conocimiento local o comunidades de práctica (Betancourt, Mertens y Parra, 2016 en la actualidad en la sociedad ecuatoriana. En el extremo de lo material traemos la reflexión previa en torno a los movimientos sociales contemporáneos en España para aplicar lo aprendido en la Escuela de sociología cualitativa de Madrid con el fin de generar unas ciencias sociales críticas y reflexivas en América Latina. Nuestra propuesta pasa por la creación de unos productos audiovisuales, la generación y apropiación de conocimiento en el modo 3 (Acosta y Carreño, 2013, la contestación a las formas de poder desde la participación y la horizontalidad y, finalmente, posibilitar el cambio desde una forma de investigación e intervención social centrada en el diseño del futuro con las comunidades.

The local climate is warm temperate with dry and hot summers, with a mean annual rainfall of 623 mm (range 367-811 mm) and mean annual temperature of 15.0?C (13.8-16.4?C). Climate change scenarios were generated from the baseline climate with two Global Climate Models: GISS (Goddard Institute of Space Studies, USA), and HadCM3 (Met Office, Hadley Centre, UK), for two of the Intergovernmental Panel on Climate Change (IPCC) emission scenarios (A2 and B2). Three time horizons were chosen for climate change projections: 2020, mean climate change for the period 2010-2039; 2050 for the period 2040-2069; and 2080 for the period 2070-2099, providing respectively a very close, an intermediate, and a fully realized climate change scenario. The agreement of model predictions with the measured values of soil organic carbon stocks was tested using the correlation coefficient R2, the root mean square error RMSE and the modelling efficiency EF. For a good model performance, RMSE should have approximately the same order of magnitude of the standard deviation, while EF should be positive and close to 1. With reference to the three soil depths (0-25, 25-50, 50-75 cm), R2, RMSE and EF are in the range 0.76-0.99, 5.07-8.42, and 0.63-0.98 respectively. CarboSOIL predictions are fully acceptable since the linear regression coefficients are always significant at p

  8. The impact of agriculture terraces on soil organic matter, aggregate stability, water repellency and bulk density. A study in abandoned and active farms in the Sierra de Enguera, Eastern Spain.

    Soil erosion, land degradation, lack of organic matter, erodible soils, rock outcrops… are a consequence of the human abuse and misuse of the soil resources. And this is a worldwide environmental issue (Novara et al., 2011; Vanlauwe et al., 2015; Musinguzi et al., 2015; Pereira et al., 2015; Mwagno et al., 2016). Agriculture terraces are a strategy to reduce the soil erosion, improve the soil fertility and allow the ploughing (Cerdà et al., 2010; Li et al., 2014). Although this idea is well accepted there are few scientific evidences that demonstrate that soils in the terraced areas are more stable, fertile and sustainable that the soil in non terraced areas. In fact, the ploughing in comparison to the abandoned or not ploughed land results in the soil degradation (Lieskovský and Kenderessy, 2014; Gao et al., 2015; Parras-Alcántara et al., 2014). This is mainly due to the lack of vegetation that increase the surface runoff (Cerdà et al., 1998; Keesstra et al., 2007). And why is necessary to develop also in terraced landscapes soil erosion control strategies (Mekonnen et al., 2015a; Mekonnen et al., 2015b; Prosdocimi et al., 2016). Our objective was to assess the soil organic matter content (Walkley and Black, 1934), the soil bulk density (ring method), the aggregate stabilility (drop impact) and the water repellency (Water Drop Penetration Time test) in four study sites in the Sierra de Enguera. Two sites were terraced: one abandoned 40 years before the measurements and the other still active with olive crops. And two control sites non-terraced. We used the paired plot strategy to compare the impact of terracing and abandonment. At each site we collected randomly 50 soil samples at 0-2 cm, 4-6 and 8-10 cm depth. At each sampling point 100 WDPT measurements where carried out, and one sample for the bulk density, and one for the organic matter, and one for the soil aggregate stability were collected. The soil surface samples shown the largest differences. The

    . Nacido en el ilustre hogar de Don Nicolás Esguerra Ortiz “El ciudadano perfecto de una era de hombres eximios” al decir del profesor Luis López de Mesa, pertenece así a la llamada generación del 70 que dio brillo sin par a nuestra patria con hombres de la altura de Manuel Murillo Toro, Santiago Pérez, Aquilea Parra, Francisco Javier Zaldúa, Eustorgio Salgar, Salvador Camacho Roldán, Rafael Núñez, Miguel Antonio Caro.

    En 1884, a los 21 años, Carlos Esguerra se gradúa de médico y cirujano para comenzar en el indómito valle del Río Magdalena su ejercicio profesional y continuar estudios de la fiebre amarilla ya iniciados por su tío el Dr. Domingo Esguerra. Pero pronto, a causa de razones políticas abandona el país en unión de su padre con destino a Caracas, donde se recibió de médico de la Universidad Central.

    Luego, cuando los dos viajeros optaron por trasladarse a París, llega a la mitad del tan fecundo decenio de 1880 a 1890, época gloriosa de la medicina francesa. Repasa allí su currículum y observa cómo la medicina hipocrática, llena de imaginación, se despedía para siempre al dar paso a la nueva etapa técnica desarrollada gracias a Luis Pasteur, Roberto Koch, Rodolfo Wirchow, Gregario Mendel, Segismundo Freud, Santiago Ramón y Cajal y Claudia Bernard. Tal vez allí, ideó establecer una casa de salud para pacientes pensionados, cercana a Bogotá y similar a las que funcionaban en las grandes naciones europeas y en los Estados Unidos.

    Por todos los aspectos, la casaquinta Marly, era el sitio ideal para establecer la casa de salud y en esto estuvieron de acuerdo los hermanos Guillermo y Carlos Esguerra, quienes confiaron en el éxito del proyecto.
