    Directory of Open Access Journals (Sweden)

    Niall Binns

    2015-12-01

    Full Text Available El artículo estudia el impacto que tuvo en la obra de Nicanor Parra su estancia de dos años en la Universidad de Oxford entre 1949 y 1951, en una época marcada por las secuelas socioeconómicas de la Segunda Guerra Mundial, por la crisis de la identidad británica provocada por la pérdida de protagonismo internacional y el desmantelamiento del Imperio, y por las amenazas cada vez más notorias de la recién iniciada Guerra Fría. El análisis se centra en “Preguntas a la hora del té”, un texto de la primera sección de Poemas y antipoemas (1954 que fue escrito aparentemente en Oxford, y plantea tanto un comentario de algunas lecturas canónicas como una nueva interpretación “inglesa” del poema.

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

    Mario Rodríguez

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

    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.

  5. 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.

    Full Text Available El artículo se pregunta por la relación entre poesía y pensamiento, y propone una génesis particular de la literatura de Nicanor Parra desde ciertos recuerdos que afectan, según su propia confesión, a su creatividad y que están en el origen de una escritura antirretórica y en oposición a las formas anteriores, que con la aparición de la antipoesía pasaron a ser leídas como expresiones convencionales del quehacer poético en Chile.

    Full Text Available Marketing the inflorescences of Comanthera elegans (Bong. L.R. Parra & Giul. represents a source of income to many families from extractives communities in the portion of the Espinhaço Range located in the state of Minas Gerais, Brazil. Cultivating this species stands out by allying income generation with conservation since the species is currently endangered. This study aimed to assess aspects of the development of C. elegans in three cultivation systems: beds, rows, and whole area. Sowing took place in January 2009 and the inflorescences were harvested in May 2010, which characterized the experimental period. Emergence; plant density; rates of flowering, mortality, resprouting, and recruiting of new individuals; and production of inflorescences per plant and per area were assessed. Emergence began approximately 50 days after sowing. Plant density ranged from 130 to 350 plants.m-2 among the three cultivation systems. The highest mortality rate (18% was observed at the peak of the dry season (August and the overall mortality rate over one reproductive cycle was 49%. Of the plants that lost the aerial part, 36% resprouted. Sprouting and seed germination accounted for 30 and 3% of the recruiting of new individuals, respectively. C. elegans had two bloom (AprilMay 2009 and April-May 2010: 5.4% of the plants bloomed in the first season and 78%, in the second. Each plant produced between three and 178 inflorescences and the highest inflorescence production in terms of weight (232 g.m-2 and number (2,910 inflorescences.m-2 was observed in the cultivation in beds at 1,624 kg.ha-1.

  8. El energúmeno misógino: la réplica feminista de Erica Jong a Nicanor Parra

    Directory of Open Access Journals (Sweden)

    Oscar Sarmiento

    2016-07-01

    Full Text Available This article explores the poetic reply by Erica Jong to a poem written by Nicanor Parra. The poetic self of Jong’s poem - “Men” - adopts the satirical stance of the self in Parra’s poem - “Mujeres” - to introduce a radical alteration of perspectives. While the feminist objective of Jong is to debunk the vitriolic anti-women discourse of Parra’s neurotic character, her reply also reveals the asymmetrical gender context of cultural production and reader reception of Parra’s antipoem. Though she contests his sexism, Jong also shows a nuanced appreciation of the male writer’s nonconformist work.

    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 Throughout the independent era, one of the main trades of the village and city of Parras, in Mexico, was that of production of wines, spirits and liquors. 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. The present study does not aim to become a treaty on the problem of filoxera on a national scale, it has a purely regional scope, of the time in which Parras was the main producer of grape wine and spirits in mexicoDurante la era independiente, uno de los principales rubros de la economía de la villa y ciudad de Parras, en México, fue la producción de vinos, aguardientes y licores. Durante el último tercio del siglo XIX, la demanda nacional de bebidas alcohólicas creció, aumentando así la importancia económica de Parras. Diversos cosecheros iniciaron procesos modernizadores, y entre ellos destacó la familia Madero. Pero al intentar diversificar las variedades de vitis vinífera, introdujeron al Valle de Parras la filoxera. Las centenarias variedades parrenses fueron destruidas por la plaga, y hubo que introducir la técnica del injerto. Gracias a su opulencia y a su estratégica inserción en redes empresariales y políticas, los Madero lograron sortear la crisis y mantener productiva una de las empresas vitivinícolas más antiguas de México. El presente estudio no tiene por objetivo hacer un tratado

    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.

    Parra shows in these stories the decentering of the subject, the nonsense, the presence of the unconscious, the desire, the violence and the alienation. A postmodernity in which only the most intimate bonds become liquid and unstable; in which human contact becomes inconsistent. Three fundamental aspects will be developed in this analysis of Los límites de la noche (Era, 1996: the night as locus of violence in La noche más oscura, the nocturnal animal in the urban barbarism in Como una diosa and the nocturnal voices that transit in the world narrated in El pozo.

    Full Text Available Garcilaso de la Vega’s sonnet XXIV is, in some aspects, an erotic allegory. It shows the poet’s promise of rising the waters of his river to the heights of a lady. Some foundation myths, including several versions of the legend of the Caballero de Olmedo, and many folk songs, employ this kind of metaphors, with an erotic significance. Some other poets such as Jorge Manrique have used similar metaphors as well.

  6. Comment on 'On higher order corrections to gyrokinetic Vlasov-Poisson equations in the long wavelength limit' [Phys. Plasmas 16, 044506 (2009)

    International Nuclear Information System (INIS)

    Parra, Felix I.; Catto, Peter J.

    2009-01-01

    A recent publication [F. I. Parra and P. J. Catto, Plasma Phys. Controlled Fusion 50, 065014 (2008)] warned against the use of the lower order gyrokinetic Poisson equation at long wavelengths because the long wavelength, radial electric field must remain undetermined to the order the equation is obtained. Another reference [W. W. Lee and R. A. Kolesnikov, Phys. Plasmas 16, 044506 (2009)] criticizes these results by arguing that the higher order terms neglected in the most common gyrokinetic Poisson equation are formally smaller than the terms that are retained. This argument is flawed and ignores that the lower order terms, although formally larger, must cancel without determining the long wavelength, radial electric field. The reason for this cancellation is discussed. In addition, the origin of a nonlinear term present in the gyrokinetic Poisson equation [F. I. Parra and P. J. Catto, Plasma Phys. Controlled Fusion 50, 065014 (2008)] is explained.

  7. Problems and agricultural solutions in olive groves

    Science.gov (United States)

    Lozano-García, Beatriz; Parras-Alcántara, Luis

    2017-04-01

    The most important and extensive crops in the Mediterranean area are olive groves. Within the last 50 years, the surface occupied by olive groves has progressively increased in Spain including more complex topographies, poorer soils and worse climatic conditions. This situation has caused serious problems based on the losses of soil, nutrients and soil quality among others (Lozano-García and Parras-Alcántara, 2014). Therefore, alternative practices that avoid soil erosion and soil degradation must be considered. As a consequence, farmers together with scientist are innovating by the development of different practices in olive groves in order to avoid these problems and to improve soil conditions. There is a huge range of new practices. Some of them are: i. alternative management techniques such as organic farming, no tillage and minimum tillage. These techniques have a positive impact in soils (Parras-Alcántara and Lozano-García, 2014; Fernández-Romero et al., 2016). ii. the addition of different substances on the soil. For example, oil mill by-products that are thus potentially useful as soil amendments since they are effective sources of organic matter and nitrogen, improve soil quality and alleviate the environmental and agronomic limitations of Mediterranean agricultural soils, even those under using conventional tillage (Lozano-García et al., 2011; Lozano-García and Parras-Alcántara, 2013). iii. the use of covers as secondary crops inside the olive grove. These offer secondary benefits derived from alternative crops and soil protection due to fact that in olive groves the main problem is the high quantity of bare surface. With this contribution we want to show the current situation in olive groves and how better results could be obtained when both trustworthy information is available and farmers and scientist work together.

    1997-10-01

    The aim of the present study was to show relationship between acculturation attitudes and mental health of international students in their first year in Japan. Of 53 new international students at a university, 50 (36 male and 14 female), 19.2 years old on average, completed a questionnaire in May (one month after the arrival), October (six months later), and March of the following year (the last month of the first academic year). The questionnaire consisted of two parts: Acculturation Attitude Scale and SCL-90-R Mental Health Scale. The former was based on Kim (1988) and measured four types of acculturation attitudes: Integration, Assimilation, Separation, and Marginalization (Berry, 1990, 1992; Berry, Trimble, & Olmedo, 1986). Results indicated that effects of acculturation attitudes on mental health of international students became clear in the last month of their first year. It is argued that helping students' integration attitude has beneficial effects on their mental health.

    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. (c) 2006 APA, all rights reserved.

En 1933, la compañía experimenta un cambio sustancial en su acercamiento a la puesta en escena con la adición de Fuenteovejuna al repertorio. La Barraca responde con esta obra al mandato de hacer de intermediario de la tradición teatral del Siglo de Oro y educar a sus nuevos espectadores, pero al mismo tiempo politiza sus prácticas, que se significan como proyecto de extensión cultural de la República.

  19. 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

    We investigate the femtosecond explosive dynamics of intense laser-heated argon clusters by measuring the cluster complex transient polarizability. The time evolution of the polarizability is characteristic of competition in the optical response between supercritical and subcritical density regions of the expanding cluster. The results are consistent with time-resolved Rayleigh scattering measurements, and bear out the predictions of a recent laser-cluster interaction model [H. M. Milchberg, S. J. McNaught, and E.

    We compare two different derivations of the gyrokinetic equation: the Hamiltonian approach in Dubin D H E et al (1983 Phys. Fluids 26 3524) and the recursive methodology in Parra F I and Catto P J (2008 Plasma Phys. Control. Fusion 50 065014). We prove that both approaches yield the same result at least to second order in a Larmor radius over macroscopic length expansion. There are subtle differences in the definitions of some of the functions that need to be taken into account to prove the equivalence.

    Some previous archaeological studies developed by the investigation group are based in the application of Artificial Neural Networks to detect special items in aerial or remote sensing[1] scenes[2], [3]. As Artificial Neural Networks have been widely used to solve problems related with pattern recognition and classification, a good performance is expected in the detection of certain image zones susceptible to contain archaeological remains, such as buildings, ruins, roads or ways. In this paper we present the study carried in on the area of Cáparra archaeological site.

    The author has identified the following significant results. The ERTS-1 imagery was utilized to study major fault and tectonic lines and their intersections in southwestern North America. A system of transverse shear faults was recognized in the California Coast Ranges, the Sierra Nevada, the Great Basin, and Mexico. They are interpreted as expressions of a major left-lateral shear which predated the San Andreas system, the opening of the Gulf of California and Basin and Range rift development. Tectonic models for Basin and Range, Coast Ranges, and Texas-Parras shears were developed. Geological structures and Precambrian metamorphic trend lines of schistosity were studied across the Red Sea rift.

    INTRODUCTION Rangelands in the Iberian Peninsula occupy more than 90,000 km2. These rangelands were created from the former Mediterranean oak forests, mainly composed of holm oak and cork oak (Quercus ilex rotundifolia and Quercus suber), by clear-cutting shrubs, removing selected trees and cultivating. These man-made landscapes are called 'dehesas' in Spain and 'montados' in Portugal. Between 1955 and 1981, more than 5,000 km2 of dehesas was converted from pastureland to cultivated land. This process has been accelerated since 1986 owing to subsidies from the European Common Agricultural Policy (Parras-Alcántara et al., 2015a). The role that natural rangelands play in the global carbon cycle is extremely important, accounting for 10-30% of the world's total soil organic carbon (SOC), in addition, SOC concentration is closely related to soil quality and vegetation productivity (Brevik, 2012). Therefore, to study the land use and management changes is important, particularly in Mediterranean soils, as they are characterized by low organic carbon content, furthermore, the continuous use of ploughing for grain production is the principal cause of soil degradation. Therefore, land use decisions and management systems can increase or decrease SOC content and stock (Corral-Fernández et al., 2013; Parras-Alcántara et al., 2014, 2015a and 2015b; Parras-Alcántara and Lozano-García, 2014) MATERIAL AND METHODS A field study was conducted to determine the land use change (Mediterranean evergreen oak woodland to olive grove and cereal, all of them managed under conventional tillage and under conservationist practices) effects on SOC stocks and the soil quality (Stratification Ratio) in Los Pedroches valley, southern Spain. RESULTS Results for the present study indicate that management practices had little effect on SOC storage in dehesas. The stratification ratio was >2 both under conventional tillage and under organic farming, so, soils under dehesa had high quality

    A new genus and species of the Mathildellidae Prebranchioplax cretacica (Crustacea: Decapoda: Goneplacoidea) is reported from shallow marine sediments of the upper Campanian Parras Shale and Cerro del Pueblo Formation (Parras Basin), Coahuila, NE Mexico. Prebranchioplax cretacica was collected from siliceous concretions associated with more abundant specimens of the retroplumid Costacopluma mexicana Vega and Perrilliat, 1989. P. cretacica bears similarities to Eocene species of Branchioplax from Japan, USA (Alaska and Washington), England, Hungary and Tajikistan as well as with Eogeryonidae (Portunoidea) species from the Upper Cretaceous of Spain and Marocarcinidae (Styracocarcinus) from Morocco. However, clear differences in the carapace frontal shape places P. cretacica in the Mathildellidae. This record represents the oldest known Mathildellidae, and along with the Retroplumidae, appear to have originated during the Late Cretaceous in ancient seas of Mexico, with a wide distribution during Paleogene times becoming restricted today to deep waters of the Indo-Pacific region and Atlantic Ocean. Comments on preservation and morphology of Costacopluma mexicana are also included. Crab specimens preserved in siliceous concretions from one locality (Entronque) show peculiar desiccation marks, and a possible model of taphonomy.

  20. Soil organic carbon stocks quantification in Mediterranean natural areas, a trade-off between entire soil profiles and soil control sections

    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

    Rock sequences of Cenomanian-Turonian age commonly assigned to the Indidura Formation in northeastern Mexico, Coahuila State, are shown to include distinct facies indicative of significant spatial variability over the carbonate platform of that region. The type section at Las Delicias is characterized by very-pale orange (10YR8/2) bedded biocalcirudites (10-30 cm thick), without internal structures, and comprises fossil assemblages rich in epifaunal groups, as well as nektonic and planktic taxa. Total inorganic carbon (TIC) varies between 48 % and 94 %, with fluctuation in total organic carbon (TOC) between 0.73 % and 1.58 %. The section at la Casita Canyon, farther southeast, consists of pale yellowish brown (10YR6/2) interbedded biocalcilutites and olive gray (5Y3/2) shales between 3 and 30 cm thick. They also show no apparent original internal structures, and allochems consist essentially of sparse fragments of planktonic foraminifera and radiolarian. TIC content varies between 0.84 % and 59.3 %, whereas TOC changes between 0.17 % and 5.85 %. In contrast, in the Parras Mountains, located south of La Delicias and northwest of la Casita, the succession occurs under a characteristic sequence showing interbeds of light olive gray (5Y6/1) and brownish black to olive black (5YR2/1 - 5Y2/1) shales and marly biocalcilutites 30 to 100 cm thick. They display distinct internal structures arranged in nearly even parallel varve-like dual lamina (TIC content varies from 43 % to 78.3 %, while TOC content remains relatively high with values between 7.35 % and 24.39 %, but more consistently higher than 20 %. Assuming that these facies are coeval, microfacies studies of these rocks as well as acid etched polished rocks, and scanning electron microscope examination (secondary and backscatter imaging) further substantiate these spatial differences. TOC-rich black shales in the Parras region further document unique paleoceanographic conditions, which was also characterized by

    The steady state properties of a many-body Wannier-Stark system coupled to an effective reservoir is studied within the non-Hermitian approach in the presence of periodic time-dependent driving. We show how the interplay between dissipation and shaking dynamics reveals a hidden symmetries yielding the occurrence of a (quasi-) loss- and interaction-free subspace. We numerically probe the geometric structure of the asymptotic state and its robustness to imperfections in the preparation of the initial conditions, dissipation and the size of system.

    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 φ 2 is indeed of the order of k # perpendicular# 4 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 k # perpendicular# 2 and diverges for T i → 0. For comparison, the leading term for the gyrokinetic Poisson's equation in this limit is of the order of k # perpendicular# 2 φ.

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.

    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.

    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

    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

  18. Impact of vegetation types on soil organic carbon stocks SOC-S in Mediterranean natural areas

    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

  19. Modelling global change impacts on soil carbon contents of agro-silvo-pastoral Mediterranean systems

    2016-04-01

    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).

  1. The Cretaceous-Paleogene boundary in the shallow northeastern Mexican foreland basins: Evidence for paleoseismic liquefaction, tsunami deposition, and Chicxulub ejecta

    Understanding the depositional sequence and composition of impact ejecta is critical for the interpretation of timing and effects of the Chicxulub impact regarding the mass extinction at the Cretaceous-Paleogene (K-Pg) boundary. Preliminary investigations have shown that the shallow La Popa and Parras foreland basins in northeastern Mexico both feature outstanding and continuous 3D exposures of the Chicxulub ejecta-rich, K-Pg boundary event deposit (Lawton et al., 2005). The m-thick sand-siltstone interval directly underlying the ejecta-rich mass flows shows evidence of slumping and liquefaction, locally leading to complete disorganization and disruption of the pre-impact late Cretaceous sedimentary sequence. The subsequent ejecta-rich sequence consists of an up to one m-thick basal carbonate-rich bed that discontinuously fills a valley-like topography. Besides abundant silicic and carbonate ejecta spherules (up to 50%) that are excellently preserved, this bed includes abundant mollusks and gastropod shells, as well as vertebrate bones and teeth. The conglomeratic bed is overlain by a series of alternating fine- to medium grained calcareous sandstones with shell debris and ejecta that were deposited by repeated currents / mass flow events incorporating varying source areas. Hummocky-cross-stratified strata that mark the return to a normal out-shelf depositional regime conformably overly these sandstones. We interpret this sequence as evidence for presumably seismic-induced sediment liquefaction followed by a series of impact-related tsunami deposits. The specific depositional sequence and Fe-Mg-rich ejecta composition as well as the petrography of the sandstones all closely link the K-Pg boundary sequence in the La Popa and Parras basin to the well-known deep-water K-Pg sites in the Gulf of Mexico (e.g. El Mimbral; Smit et al., 1996; Schulte and Kontny, 2005).

    Full Text Available The purpose of the arrangement described in this article is to take advantage of the unground water available at the junction of the Lozoya and Jarama rivers, to collect it for the Madrid water supply system. The water is collected by means of two Ranney wells, with radial drainages in metal plates with longitudinal slits. The total length of these slits, for each well, is 500 m. The filtered water is pumped to La Parra Canal, along a steel welded tube, with a capacity of 1 m3/sec. 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 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. Hoy conocemos toda su filiación: Ginés Pérez de la Parra, así como la fecha de su muerte, totalmente equivocada hasta ahora. 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. Del presente O crux, sin embargo, no hemos podido encontrar ninguna copia con su nombre, pese a las múltiples copias, con sus variantes, existentes en la Comunidad Valenciana.

Subdivide-se em quatro sub-bacias (Lomas de Olmedo a leste; Sey a oeste; Tres Cruces a norte; e Metán-Alemania a sul que foram preenchidas por sedimentos dos Subgrupos Pirgua (fase sin-rifte, Balbuena e Santa Bárbara (fase sag . O Subgrupo ou Supersequência Balbuena é dividido em quatro sequências: Balbuena I, II, III e IV, da base para o topo. O presente estudo identificou filamentos microbianos em imagens geradas pelo microscópio eletrônico de varredura em amostras de estromatólitos e laminitos da Sequência Balbuena III (Maastrichtiano/Daniano da Formação Yacoraite, na Sub-bacia Metán-Alemania, região do dique Cabra Corral, distrito de Coronel Moldes, Argentina. A ocorrência desses filamentos, identificados em calcários formados em períodos de clima árido e depositados no intervalo de lago fechado da sequência em estudo, indica a influência de atividade biológica na formação dessas rochas. A identificação dos filamentos microbianos, preservados a partir de estruturas de cianobactérias, auxilia a interpretação paleoambiental, uma vez que a ocorrência desses microorganismos é limitada à zona fótica e é comum a ambientes estressantes. Os laminitos da área de estudo foram interpretados como formados em planícies lamosas supralitorâneas na zona vadosa, enquanto os estromatólitos se formaram em ambiente sublitorâneo, estando constantemente submersos. Além dos microbialitos, ocorrem na Sequência Balbuena III fácies carbonáticas, siliciclásticas e mistas, depositadas em ambiente lacustre.

En esa revista se reunieron quienes, posteriormente, construyeron sus peculiares, y en algunos casos truncos, caminos creativos: Ricardo Rendón, León de Greiff, Teodomiro Isaza, Libardo Parra, Rafael Jaramillo, Jesús Restrepo Olarte, Eduardo Vasco, Jorge Villa, Félix Mejía, Bernardo Martínez, Fernando González, José Manuel Mora y José Gaviria. La revista reunió poetas, pintores, músicos, filósofos, que constituyeron el núcleo germinal de la generación de Los Nuevos. En sus diez números -murió el 20 de junio de 1915- logró expresar la intención de revaluar la tradición artística decimonónica y dio las puntadas iniciales de lo que sería el tímido contacto de nuestros intelectuales de comienzos de siglo con el vigoroso movimiento vanguardista.

    Parra Murillo, Carlos Alberto; Muã+/-Oz Arias, Manuel Humberto; Madroã+/-Ero, Javier

    A unit filling Bose-Hubbard Hamiltonian embedded in a strong Stark field is studied in the off-resonant regime inhibiting single- and many-particle first-order tunneling resonances. We investigate the occurrence of coherent dipole wavelike propagation along an optical lattice by means of an effective Hamiltonian accounting for second-order tunneling processes. It is shown that dipole wave function evolution in the short-time limit is ballistic and that finite-size effects induce dynamical self-interference patterns known as quantum carpets. We also present the effects of the border right after the first reflection, showing that the wave function diffuses normally with the variance changing linearly in time. This work extends the rich physical phenomenology of tilted one-dimensional lattice systems in a scenario of many interacting quantum particles, the so-called many-body Wannier-Stark system.

    Effects of different soil types in natural Mediterranean areas on soil organic carbon (SOC) Ana Requejo1, Beatriz Lozano-García1, Luis Parras Alcántara1 1 Department of Agricultural Chemistry and Soil Science, Faculty of Science, Agrifood Campus of International Excellence - ceiA3, University of Córdoba, Spain. The carbon content of the atmosphere can be influenced by soils, since they can store carbon or emit large quantities of CO2. C sequestration into soils is one of the most important ecosystems services because of its role in climate regulation (IPPC, 2007). Thereof, agriculture and forestry are the only activities that can contribute to C sequestration through photosynthesis and its carbon incorporation into carbohydrates (Parras Alcántara et al., 2013). Dehesa is a multifunctional agro-sylvo-pastoral system and typical landscape of southern and central Spain and southern Portugal. It is an anthropogenic system dedicated to the combined production of black iberian pigs, a variety of foods, fuel, coal, and cork. Besides, it acts as well in the production of endangered species as wildlife habitat and as sustainable hunting areas. These dehesa areas are defined by a relationship between productivity and conservation of forest oaks, providing environmental benefits such as carbon capture and storage. The area focused in this study is the Cardeña-Montoro Nature Reserve, located within the Sierra Morena (Córdoba, South Spain). The most representative soils in Cardeña-Montoro Nature Reserve are Cambisols, Regosols, Leptosols and Fluvisols according to IUSS Working Group WRB (2006). They are characterized by a low fertility, poor physical conditions and marginal capacity for agricultural use, along with low organic matter content due to climate conditions (semiarid Mediterranean climate) and soil texture (sandy). Several studies have shown that land use affects the SOC concentration (Lozano-García et al., 2016; Khaledian et al., 2016). Based on this

    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

    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.

    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.

    The Compton camera is used for imaging the distributions of γ ray direction in a γ ray telescope for astrophysics and for imaging radioisotope distributions in nuclear medicine without the need for collimators. The integration of γ rays on a cone is measured with the camera, so that some sort of inversion method is needed. Parra found an analytical inversion algorithm based on spherical harmonics expansion of projection data. His algorithm is applicable to the full set of projection data. In this paper, six possible reconstruction algorithms that allow image reconstruction from projections with a finite range of scattering angles are investigated. Four algorithms have instability problems and two others are practical. However, the variance of the reconstructed image diverges in these two cases, so that window functions are introduced with which the variance becomes finite at a cost of spatial resolution. These two algorithms are compared in terms of variance. The algorithm based on the inversion of the summed back-projection is superior to the algorithm based on the inversion of the summed projection. (author)

    Fan-deltas from Loreto Bay show recent evidences of sedimentary gravity flows as a result from catastrophic events during hurricane rainfalls. The knowledge of hydrological characteristics of these flows is important for understanding the effects of storms on fan-deltas geomorphology in this region, as well as for the urban developing planning of the city of Loreto in order to avoid hazardous zones. The analysis of precipitation and hurricane tracks data for the period 1945 to 2009 indicates that hurricanes have caused catastrophic floods every 20 years. Stratigraphy from the channel incision shows a sequence of stream flow and debris flow controlled by changes in the competence and capacity of the stream, which are associated to the gentle slope (<2 °) of the fan-deltas. However fans from the north of the bay (Arce and Gúa) show deposits of debris flows associated to catastrophic floods, which have caused the incision channel to drift towards the southern part of the fans, while flows from Las Parras fan-delta, from the middle of the bay, are dominated by stream flows. These differences in the type of the flows are controlled by lithology, shape and size of the drainage basin, and slope of the transit zone in the feeder channel.

  19. Representations of Eros: From Modernismo to Posmodernismo

    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.

    Worldwide, the technological revolution is taking place, but the human aspect of health care demonstrates that medical personnel often avoid the responsibility for the emotional care of their patients. This is not a recent point of view. In many ways, during the 19th century, Mexican physicians were outspoken about the problems in regard to the manner in which care of sick persons was carried out. They were certain that scientific progress was the origin of medical dehumanization, frequently forgetting that physicians were treating sensitive and intelligent persons and, therefore, must adjust their behavior in accordance with their patients. Because of this situation, 19th century physicians were invited to share a list of responsibilities and duties to patients, among their professional colleagues as well as among government authorities. In particular, the philosophies of three health professionals were analyzed, Francisco Flores (1855-1931), Porfirio Parra (1854-1912) and Adrián de Garay (1860-192?), in regard to how the practice of medicine should be exercised and that the underlying ethical and moral principles must always be present.

    We present two-dimensional particle-in-cell (PIC) simulations that investigate the role of background pressure on the acceleration of electrons from ultra intense laser interaction at normal incidence with liquid density ethylene glycol targets. The interaction was simulated at ten different pressures varying from 7.8 mTorr to 26 Torr. We calculated conversion efficiencies from the simulation results and plotted the efficiencies with respect to the background pressure. The results revealed that the laser to > 100 keV electron conversion efficiency remained flat around 0.35% from 7.8 mTorr to 1.2 Torr and increased exponentially from 1.2 Torr onward to about 1.47% at 26 Torr. Increasing the background pressure clearly has a dramatic effect on the acceleration of electrons from the target. We explain how electrostatic effects, in particular the neutralization of the target by the background plasma, allows electrons to escape more easily and that this effect is strengthened with higher densities. This work could facilitate the design of future experiments in increasing laser to electron conversion efficiency and generating substantial bursts of electrons with relativistic energies.

    Full Text Available Dentro de la reciente historia del teatro chileno hay un acontecimiento que no puede dejar de ser advertido como una de las señales más claras del cambio de perspectiva que empieza a gestarse en lo que llamaremos aquí el nuevo teatro chileno. Nos referimos a los hechos que rodearon al frustrado estreno de Lo crudo, lo cocido y lo podrido, del médico psiquiatra y dramaturgo Marco Antonio de la Parra en 1978. Al margen de la imagen no realista del mundo que entregaba la obra y, por lo mismo, ajena a los códigos artísticos dominantes, la dimensión grotesca de las diferentes escenas de Lo crudo, lo cocido y lo podrido aparecía ante los ojos de espectadores y lectores poco avisados como una burla que atentaba contra las venerables instituciones tradicionales del país y sus hombres.

    New decapod specimens from mid-Paleocene shallow marine deposits of NE Mexico represents an important addition to the diversity, paleobiogeography and evolution of the Crustacea record. In this work, we describe additions to the decapod assemblage from the Paleocene (Selandian) Rancho Nuevo Formation (Difunta Group, Parras Basin, Coahuila). Due to the evident size differences with other decapod assemblages, we compare the new assemblage with those from the Lower Paleocene (Danian) Mexia Clay Member of the Wills Point Formation, Texas, and the Lower Eocene (Ypresian) El Bosque Formation in Chiapas. Species reported from the mid-Paleocene (Selandian) assemblage of the Porters Creek Formation (Alabama), are correlatable to the decapod species from NE Mexico in age, size and systematic composition. The erymid lobster Enoploclytia gardnerae (Rathbun, 1935) is represented by several carapaces and chelae remains. One isolated palm of Callianassidae is included. Numerous carapaces of Linuparus wilcoxensis Rathbun, 1935 are described, representing the most abundant lobster. A new record for the raninid Notopoides sp., and presence of Quasilaeviranina sp. cf. arzignagnensis and Quasilaeviranina ovalis are here reported. New raninids, Claudioranina latacantha sp. nov. and Claudioranina sp. (Cyrtorhininae) are also part of this assemblage. Paraverrucoides alabamensis (Rathbun, 1935), and Tehuacana americana (Rathbun, 1935) are represented by several carapaces exhibiting intraspecific morphological variation. Different sizes among the Early and Middle Paleocene and Early Eocene decapod populations suggests a possible effect of variation in seawater temperatures and/or a Lilliput effect after the K/Pg event.

    Dressler (2001:456) characterizes medical anthropology as divided between two poles: the constructivist, which focuses on the "meaning and significance that events have for people," and the structuralist, which emphasizes socioeconomic processes and relationships. This study synthesizes structuralist and constructivist perspectives by investigating how structural processes impact explanatory models of Chagas disease in a highly endemic area. The research took place from March-June 2013 through the Centro Medico Humberto Parra, a non-profit clinic servicing low income populations in Palacios, Bolivia and surrounding communities. Semistructured interviews (n = 68) and consensus analysis questionnaires (n = 48) were administered to people dealing with Chagas disease. In the interview narratives, respondents link Chagas disease with experiences of marginalization and rural poverty, and describe multilayered impediments to accessing treatment. They often view the disease as incurable, but this reflects inconsistent messages from the biomedical system. The consensus analysis results show strong agreement on knowledge of the vector, ethnomedical treatment, and structural factors related to Chagas disease. In interpreting Chagas disease, respondents account for the structural factors which place them at risk and impede access to care. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Understanding the factors driving the diet breadth of phytophagous insects remains one of the main questions in ecological research. In this study we explored the diet breadth and plant-insect associations in the plume moth Lioptilodes friasi Vargas & Parra (Lepidoptera: Pterophoridae). This phytophagous insect was originally described in association with a single host species, Haplopappus foliosus (Asteraceae), a native shrub of the Chilean Mediterranean matorral. In order to address the breadth of host plant choice, we surveyed other Haplopappus species growing along the elevation gradient of central Chile from sea level to 2600 m. We were able to obtain L. friasi adults from five additional Haplopappus species: Haplopappus chrysantemifolius and Haplopappus decurrens from the coastal zone, Haplopappus multifolius and Haplopappus schumanii from the mid-elevation zone, and Haplopappus scrobiculatus at high elevation. Our results demonstrate that the genus-specialized endophagous herbivore L. friasi has a wider distribution and climatic tolerance than previously described. Its biogeographical range extends from the lowland coastal habitats up to the Andean subnival level. We propose that shared flower phenotypic traits such as morphology and chemical composition may have allowed the colonization of closely related Haplopappus species in central Chile, the expansion of which is limited by the harsh high elevation conditions.

Se determinó la composición y abundancia íctica en cuatro zonas geomorfológicas: laguna, arrecife periférico de barlovento, terraza de barlovento y terraza de sotavento. En total se censaron 98 especies, de las cuales las más abundantes fueron Chromis cyanea (14%, Clepticus parra (14% y Stegastes partitus (10%. Las familias dominantes fueron Pomacentridae (37%, Labridae (28% y Scaridae (10%. El análisis de similaridad entre las zonas mostró que las diferencias entre éstas fueron mayores que las posibles diferencias geográficas entre los atolones, excepto para la laguna y la terraza de sotavento, las cuales no tuvieron diferencias significativas. Los resultados de la clasificación y ordenación confirmaron lo anterior, además en la ordenación los grupos de estaciones quedaron ubicados según un gradiente de profundidad y grado de exposición al oleaje, insinuando que estas dos variables físicas fueron las responsables del agrupamiento de las estaciones. Las diferencias en términos de equitatividad y riqueza de especies parecen ser debidas a las mismas variables. El análisis inverso dio como resultado que en cada grupo hubo pocas especies características, por ende las diferencias entre las zonas parecen ser más debidas a la dominancia de ciertas especies. Las categorías tróficas dominantes fueron planctófagos y herbívoros, los cuales fueron significativamente diferentes entre las zonas.

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.

    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.

    2014-05-01

    INTRODUCTION The most important and extensive crops in the Mediterranean area are olive groves. 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

    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).

    Basic soil management goes back to the earliest days of agricultural practices, approximately 9,000 BCE. Through time humans developed soil management techniques of ever increasing complexity, including plows, contour tillage, terracing, and irrigation. Spatial soil patterns were being recognized as early as 3,000 BCE, but the first soil maps didn't appear until the 1700s and the first soil models finally arrived in the 1880s (Brevik et al., in press). The beginning of the 20th century saw an increase in standardization in many soil science methods and wide-spread soil mapping in many parts of the world, particularly in developed countries. However, the classification systems used, mapping scale, and national coverage varied considerably from country to country. Major advances were made in pedologic modeling starting in the 1940s, and in erosion modeling starting in the 1950s. In the 1970s and 1980s advances in computing power, remote and proximal sensing, geographic information systems (GIS), global positioning systems (GPS), and statistics and spatial statistics among other numerical techniques significantly enhanced our ability to map and model soils (Brevik et al., 2016). These types of advances positioned soil science to make meaningful contributions to sustainable land use management as we moved into the 21st century.

    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.

    Betula utilis is a major constituent of alpine treeline ecotones in the western and central Himalayan region. The objective of this study is to provide first time analysis of the potential distribution of Betula utilis in the subalpine and alpine belts of the Himalayan region using species distribution modelling. Using Generalized Linear Models (GLM) we aim at examining climatic factors controlling the species distribution under current climate conditions. Furthermore we evaluate the prediction ability of climate data derived from different statistical methods. GLMs were created using least correlated bioclimatic variables derived from two different climate models: 1) interpolated climate data (i.e. Worldclim, Hijmans et al., 2005) and 2) quasi-mechanistical statistical downscaling (i.e. Chelsa; Karger et al., 2016). Model accuracy was evaluated by the ability to predict the potential species distribution range. We found that models based on variables of Chelsa climate data had higher predictive power, whereas models using Worldclim climate data consistently overpredicted the potential suitable habitat for Betula utilis. Although climatic variables of Worldclim are widely used in modelling species distribution, our results suggest to treat them with caution when remote regions like the Himalayan mountains are in focus. Unmindful usage of climatic variables for species distribution models potentially cause misleading projections and may lead to wrong implications and recommendations for nature conservation.

    INTRODUCCIÓN

    En la Nueva Granada de principios del siglo XIX solo existía una facultad o escuela de medicina, la del Colegio Mayor de Nuestra Señora del Rosario, en Bogotá. A partir de 1828 ya existían, en lo que hoy es Colombia, la Escuela de Medicina de la Universidad Central, la escuela de Medicina del Magdalena y el Istmo asentada en Cartagena, y sobrevivían las cátedras de medicina del Rosario y San Bartolomé, con sede en Bogotá; en 1864 se abrió en Bogotá la primera Escuela de Medicina, privada; en esa década de los sesenta del siglo XIX el Estado Soberano del Cauca reanudó y cerró los estudios de medicina en el Colegio del Estado, el Estado Soberano de Boyacá activó en 1869 en el Colegio de Boyacá la cátedra de medicina, de vida breve. A finales del siglo XIX solo existían las facultades de medicina de las universidades Nacional, de Antioquia y de Cartagena, y en 1920 el país seguía teniendo esas tres facultades de medicina en funcionamiento.

    Aunque se logró tener conocimiento de catorce libros, solo se exhiben 10 (uno por autor, a excepción de Nicolás Osorio y Ricaurte con dos, ambos exhibidos, y Luis Cuervo Márquez con dos, solo uno exhibido, con la ausencia de las obras de los autores Ricardo de La Parra, Juan de Dios Tavera Barriga y Gabriel D. Ujueta y el libro de Luis Cuervo Márquez titulado: La fiebre amarilla en el interior de Colombia.

    Sobre el total de los 14 libros, diez están exhibidos y de ellos, tres fueron publicados en lo que iba hasta ese momento del siglo XX: Manual de Higiene y Medicina Infantil, de Barberi; Contribución al estudio de la lepra en Colombia, de Montoya y Flórez, y Geografía Médica y patológica de Colom- bia: contribución al

    ABSTRACT Soils play a key role in the Earth System (Keesstra et al., 2012; Brevick et al., 2015). Soils are a key resource for the human societies (Mol and Keesstra, 2012) and they are relevant to achieve the sustainability such as the United Nations Goals highlight (Keesstra et al., 2016). Agriculture soils, especially those under conventional tillage, are prone to organic matter mineralization, soil erosion, compaction and increase of greenhouse gases emission (Novara et al., 2011; Bruun et al., 2015; de Moraes et al., 2015; Choudhury et al., 2016; del Mar et al., 2016). The adoption of organic farming and sustainable management practices may provide a sustainable crop productivity, and in the meanwhile mitigate the negative impact of agriculture on ecosystem services benefits (Laudicina et al., 2015; Parras-Alcantara et al., 2015; 2016). The aim of this study was to examine, under field conditions, the long-term changes of soil organic matter under organic farming management in citrus orchards in Mediterranean environment and evaluate the ecosystem service on C sequestration in terms of economic benefits. The research was carried out at the Alcoleja Experimental Station located in the Cànyoles river watershed in the Eastern Spain on 45year old citrus plantation. Soil Organic Matter (SOM) content was monitored for 20 years at 6 different soil depth. The profitability of citrus plantation was estimated under conventional and organic management. Results showed that SOM in the 0-30 cm soil depth was the double after 20 years of organic farming management, ranging from 0.8 g kg-1 in 1995 to 1.5 g kg-1 in 2006. The highest SOM increase was in the top soil layer (368% of SOM increase in comparison to the initial SOM content) and decreased with soil depth. The effect of organic farming was relevant after 5 years since land management change, indicating that in Mediterranean environment the duration of long term studies should be higher than five years and proper policy

    , results make you think that assimilating SMOS Arctic SSS data could be beneficial for the TOPAZ Arctic Ocean Prediction system. Therefore, SMOS shows great potential to routinely monitor the extension of the surface freshwater fluxes also in the Arctic Ocean. The new SMOS Arctic products can therefore substantially contribute to increase our knowledge of the critical processes that are taking place in the Arctic. [1] Haine, T. et al.

    Yeast 6-phosphofructo-1-kinase (PFK-1) has two subunits, Pfk1p and Pfk2p. Deletion of Pfk2p alters glucose-dependent V-ATPase reassembly and vacuolar acidification (Chan, C. Y., and Parra, K. J. (2014) Yeast phosphofructokinase-1 subunit Pfk2p is necessary for pH homeostasis and glucose-dependent vacuolar ATPase reassembly. J. Biol. Chem. 289, 19448–19457). 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. PMID:27226568

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. This study concludes that both formulations meet the Goldman’s criteria and demonstrate how irradiated nanoparticles, with innovative permeation characteristics

This study aimed to evaluate the influence of exercise in iron levels, the total iron and transferrin saturation in race horses. One hundred and eleven samples of blood serum were collected from Thoroughbred horses, from the Jockey Club of São Paulo, aged between 3 and 4 years old, male and female, clinically healthy, practitioners turf competition, in sand or grass. The samples were obtained before exercise (control time and 30 minutes after exercise (post exercise. These animals were submitted to gallop training, of high intensity and short duration for this research. As a result, it was observed that the serum concentration of iron (Fe showed a statistically significant lowering post-exercise, due to organic re-balance of iron, while TIBC (total iron binding capacity showed a clear and significant increase in their serum levels due to increased needs of iron during and after exercise. The percentage of transferrin saturation in serum was shown to be lower post-exercise, probably due to the recruitment of

    Soils are recognized as one of the most important components characterizing a terroir (Vaudour et al., 2015). However, the soils of vineyards are one of the most degraded in comparison to other cultivated context due to traditional tillage management (Prosdocimi et al., 2016). The key factor to understand the connectivity between topsoil redistribution and overland flow is the human activity as the management, who can reduce or increase these geomorphological interchanges (sediment and runoff) and changes the soil properties such it was found in different regions and under different crops (Parras-Alcántara et al., 2016). In order to assess this topsoil redistribution in vineyards, the Stock Unearthing Method (SUM) has been accepted to be a reliable method to assess erosion rates and spatial evolution and interchanging of the topsoil, sediments and water flux directions at long-term time scales in vineyards (Brenot et al., 2008; Paroissien et al., 2010; Rodrigo Comino et al., 2016). The SUM is based on the measurement of the distance from the topsoil to the grafted vine stock, confirmed as a passive indicator of topsoil movements since the initial planting of vine stocks. Therefore, the aims of this work are: i) to quantify the soil erosion rates by means of Stock Unearthing Method; ii) to measure the impact of plantation of new vineyards; iii) to compare sediment transport, water flux directions and topsoil redistributions between different soil types, land management (bare soil, amendments, straw mulch…) and soil tillage practices; iv) to assess sediment budgets and water flux direction conditioned by the micro-topographical variations; and, v) to detect key factors and impact on the surface features within the detected connectivity processes (rills and inter-rills…) using cartography.

    Soil degradation affects more than 52 million ha of land in countries of the European Union (Hueso-González et al., 2016). This problema is particularly serious in Mediterranean areas, where the effects of anthropogenic activities (tillage on slopes, deforestation, and pasture production) add to problems caused by prolonged periods of drought and intense and irregular rainfall (Martínez-Murillo et al., 2016). Depending on the scale of study, soil organic carbón (SOC) dynamics in Mediterranean forests have been found to be particularly sensitive to factors related to seasonal changes in temperature and soil moisture (Casals et al., 2000; Eaton et al., 2008; Hueso-González et al., 2014). During dry periods in theMediterranean area, the lack of water entering the soil matrix reduces organic contributions to the soil (Parras-Alcántara et al., 2016). These processes lead to reduced soil fertility and soil loss (García-Orenes et al., 2010). Restoring the native vegetation is one of the most effective ways to control soil degradation in Mediterranean areas, especially in very degraded areas. In the initial months after afforestation, vegetation cover establishment and soil quality could be better sustained if the soil was amended with an external extra source of organic matter (Hueso-González et al., 2016). The goal of this study was to test the effect of various organic amendments on select soil properties over a 54-month period. Five amendments were applied in an experimental set of plots: straw mulching (SM), mulch with chipped branches of Aleppo Pine (Pinus halepensis L.; PM), sheep manure compost (SH), hydroabsorbent polymers (HP) and sewage sludge (RU). Plots were afforested following the same spatial pattern, and amendments were mixed with the soil at the rate 10Mg ha-1. Soil from the afforested plots was sampled in the following: (i) spring 2012 (6 months postafforestation); (ii) spring 2013(18 months postafforestation); (iii) spring 2014 (30 months

    The main factor controlling soil erosion is vegetation cover (Cerdà and Doerr, 2005; Van Eck et al., 2016; van Hall et al., 2017). However, due to the removal of the vegetation in agricultural fields and the increase in soil erosion rates other factors arise as keys to control soil erosion rates and mechanisms (Ochoa-Cueva et al., 2016; Rodrigo Comino et al., 2016). Soil erosion rates in olive plantations are high due to the lack of vegetation cover as a consequence of intensive tillage and herbicides abuse (Taguas et al., 2015; Parras-Alcantara et al., 2016; Zema et al., 2016). This is also found in vineyards and other orchards around the world (Prosdocimi et al., 2016; Rodrígo Comino et al., 2016), and the reason to look for sustainable management techniques such as geotextiles, mulches or catch crops that will stop the accelerated soil erosion (Giménez Morera et al., 2010; Mwango et al., 2016; Nawaz et al., 2016a; 2016b; Nishigaki et al., 2016). All these management techniques are difficult to apply and have high costs. Natural solutions such as weeds to provide cover are very efficient and have no cost (Cerdà et al., 2016; Keesstra et al., 2016) and they can be adapted to the management of the farmers. In olive orchards under herbicide treatment there is a natural growth of mosses and the development of a litter layer composed of olive leaves. There is also burrowing by wild boars that "ploughs" the soil. This research evaluates the impact of the three items above on soil erosion. The measurements were carried out using simulated rainfall experiments over an area of 0.25 m2 at a rainfall rate of 55 mm h-1 during one hour (Cerdà, 1996; Prosdocimi et al., 2017) on 15 plots of mosses, 15 wild boar burrowed surfaces and 15 leaf covered surfaces during the winter of 2015. The soil erosion rates were 34 times greater in the wild boar burrowed soils, meanwhile the litter and mosses covered soils showed similar erosional responses and the soil erosion rates were

The SWNT sample shows a lower Qst due to its relatively wide PSD [2], and the non-porous carbon black is characterized by the lowest Qst values. The Qst values calculated from H 2 adsorption isotherms measured at cryogenic temperatures below 1 atmosphere can be used to predict/estimate H 2 adsorption at ambient temperatures under high pressures. Fig 3 shows the H 2 adsorption isotherm on the SWNT sample calculated for 298 K from the low pressure and low temperature (77, 87 K) data using the Clausius-Clapeyron equation and assuming the temperature independence of the Qst values. A good agreement with high-pressure experimental data [3] is observed. Predictions using DFT model will also be discussed during presentation. [1] J. Jagiello, M. Thommes, Carbon 42, 1227, 2004.

  8. 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

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.

    -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.

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

    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

    for correlations with attachment security. The stability of the theory-consistent features across three different stimuli sets was explored using repeated measures analysis of variances (ANOVAs). In total, 46 theory-consistent correlations were found during the exploration (out of 65 total significant correlations). For example, attachment security as measured by the AAP was correlated with positive facial expressions (r=.36, P=.01). AMMI's security with the father was inversely correlated with the low frequency (LF) of HRV (r=-.87, P=.03). Attachment security to partners as measured by the AAQ was inversely correlated with anger facial expression (r=-.43, P=.001). The confirmatory analysis showed that the composite effects index was significantly correlated to security in the AAP (r=.26, P=.05) and the AAQ (r=.30, P=.04) but not in the AMMI. Repeated measures ANOVAs conducted individually on each of the theory-consistent features revealed that only 7 of the 46 (15%) features had significantly different values among responses to three different stimuli sets. We were able to validate two of the instrument's core assumptions: its capacity to measure attachment security and the viability of using themes as placeholders for rotating stimuli. Future validation of other of its dimensions, as well as the ongoing development of its scoring and classification algorithms is discussed. ©Federico Parra, Raphaële Miljkovitch, Gwenaelle Persiaux, Michelle Morales, Stefan Scherer.

    Soil system determines the fluxes of energy and matter in the Earth and is the source of goods, services and resources to the humankind (Keesstra et al., 2012; Brevik et al., 2015; Keesstra et al., 2016). To restore and rehabilitate the soil system is a key strategy to recover the services the soils offers (Celentano et al., 2016; Galati et al., 2016; Parras-Alcantara et al., 2016). Transformation of degraded sodic lands in biodiversity rich productive forest ecosystem is a challenging task before the researchers all over the world. The soils of the degraded sites remain almost unfavorable for the normal growth, development and multiplication of organisms; all our attempts tend to alleviate the soil constraints. Land degradation due to presence of salts in the soil is an alarming threat to agricultural productivity and sustainability, particularly in arid and semiarid regions of the world (Tanji, 1990; Qadir et al., 2006). According to the FAO Land and Nutrition Management Service (2008), over 6% of the world's lands are affected by salinity, which accounts for more than 800 million ha in 100 countries. This is due to natural causes, extensive utilization of land (Egamberdieva et al., 2008), poor drainage systems and limited availability of irrigation water which causes salinization in many irrigated soils (Town et al., 2008).In India, about 6.73 million ha are salt affected which spread in 194 districts out of 584 districts in India and represents 2.1% of the geographical area of the country (Mandal et al., 2009).Out of these, 2.8 million ha are sodic in nature and primarily occurring in the Indo-Gangetic alluvial plains. These lands are degraded in structural, chemical, nutritional, hydrological and microbiological characteristics. The reclamation of salt affected soils with chemical amendments like gypsum and phospho-gypsum are in practice for the cultivation field crops under agricultural production. Forest development on such lands although takes considerable

    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.

    Hasta ese momento los enfermos capitalinos eran tratados e intervenidos quirúrgicamente bajo el denominador común de la caridad pública en el vetusto hospital de San Juan de Dios, el cual ocupaba un deteriorado caserón colonial, carente de las indispensables

    escritos de Carrasquilla refutando las espeluznantes descripciones de la enfermedad que hacían Emilia Pardo Bazan en Europa y el doctor Ricardo de la Parra entre nosotros. Sus artículos sobre las manifestaciones clínicas de la lepra, publicados en 1905 en los Anales de la Academia de Medellín, son “clásicos por la excelencia de su estilo y la sobriedad y precisión de los conceptos expresados en ellos”, escribe De Francisco.

    La vida de Carrasquilla estuvo marcada por triunfos, pero también sinsabores. El gobierno del Presidente Caro creó en 1895 el Instituto Carrasquilla para el estudio y el tratamiento de la enfermedad bajo la dirección de Juan de Dios Carrasquilla. Allí se desarrolló una importante labor científica no sólo en lepra sino en otros campos. Pero a finales de 1897, cuando Carrasquilla presentaba sus estudios en la Conferencia Internacional de Berlín, el gobierno de Caro clausuró el Instituto.

    El doctor Juan de Dios Carrasquilla falleció a los 75 años de edad, el 14 de julio de 1908. En medio de la consternación de la ciudadanía, sus exequias se realizaron el día siguiente. El doctor Luis Zea Uribe pronunció la oración fúnebre. Adolfo De Francisco Zea reproduce las palabras de Zea Uribe que “retratan de manera admirable la noble figura del sabio”. También transcribe De Francisco la conferencia pronunciada en 1923 en el Teatro Colón de Bogotá, por el doctor Luis Zea Uribe en favor de los leprosos de Agua de Dios: “Juan de Dios Carrasquilla es una de las más limpias glorias de la patria… La patria colombiana teje la más pura corona de su gratitud y de su admiración sobre las sienes del modesto sabio, que fue un gran patriota y un corazón excelente”...
