    Hernandez, Lorena; Ciccio, Jose F.; Chaverri, Carlos

    2007-01-01

    The chemical composition was determined of the essential oils extracted from twigs, bark and leaves of the tree Ocotea sinuata (Mez) Rohwer (Lauraceae), which grows in wild form in Costa Rica. The analyses were effected by means of the technology of gas chromatography in capillary column, using detectors of ionization at flame (FID) and spectrometry of masses (GC/MS). Eighty eight (88) compounds were identified. The oils were found to be of nature terpenic. The major constituents of the twigs were β-caryophyllene (18,4%), viridiflorol (11,3%), caryophyllene oxide (8,7%), germacrene D (7,7%), camphene (4,5%), and α-pinene (4,4%). The main constituents from bark oil were germacrene D (14.8%), β- caryophyllene(10,5%), camphene (10,3%), α-pinene (10,1%), viridiflorol (8,7%), β-pinene (4,7%) and α-copaene (4,6%). The main constituents from leaf oil were germacrene D (30,6%), β- caryophyllene (30,1%) and viridiflorol (8,9%). (author) [es

    Full Text Available Ocotea gardneri (Meisn. Mez é uma espécie arbórea, encontrada no nordeste brasileiro, principalmente nos estados da Paraíba e Pernambuco, conhecida por "louro-branco" e "louro-babão". Neste trabalho realizou-se morfodiagnoses (macroscópica e microscópica de folhas de O. gardneri, com o objetivo de fornecer subsídios à sua caracterização e identificação. Para a morfologia externa, analisaram-se amostras frescas e conservadas em álcool (70º, com auxílio de estereomicroscópio, e observações de campo. Realizaram-se secções transversais em lâminas foliares e pecíolos, e seções paradérmicas nas duas faces de lâminas foliares. Ocotea gardneri possui folhas elípticas a oval-elípticas, margem inteira, levemente ondeada, ápice agudo e base arredondada. A lâmina foliar é hipoestomática com estômatos do tipo paracítico; a epiderme é uniestratificada, com células de paredes retas e espessadas; o mesofilo é isobilateral, aqui referido pela primeira vez para uma espécie de Lauraceae, com células e ductos secretores evidentes e feixes vasculares colaterais envolvidos pela bainha esclerenquimática. Este conjunto de caracteres aliado à morfologia foliar, permitiram o estabelecimento de parâmetros que possibilitarão a caracterização de folhas de Ocotea gardneri em testes de autenticidade, bem como auxiliarão em estudos da taxonomia da espécie estudada.

    Full Text Available The germination response of Ocotea pulchella (Nees Mez seeds to light, temperature, water level and pulp presence is introduced. The laboratory assays were carried out in germination chambers and thermal-gradient apparatus, whereas the field assays were performed in environments with distinct light, temperature and soil moisture conditions within a permanent parcel of Restinga forest of the Parque Estadual da Ilha do Cardoso, Cananéia, São Paulo. The seeds do not exhibit dormancy, they are non photoblastic, and a loss of viability in dry stored seeds can be related to a decrease in water content of the seed. The presence of the pulp and the flooded substratum influenced negatively the germination of O. pulchella seeds tested in the laboratory. Otherwise, light and temperature probably are not limiting factors of the germination of O. pulchella seeds in the natural environment of Restinga. The optimum temperature range for germination of Ocotea pulchella seeds was 20 to 32 ºC, the minimum or base temperature estimated was 11 ºC and the maximum ranged between 33 and 42 ºC. The isotherms exhibited a sigmoidal pattern well described by the Weibull model in the sub-optimal temperature range. The germinability of O. pulchella seeds in the understorey, both in wet and dry soil, was higher than in gaps. Germination was not affected by fluctuations in soil moisture content in the understorey environment, whereas in gaps, germination was higher in wet soils. Thus, the germination of this species involves the interaction of two or more factors and it cannot be explained by a single factor.

    2009-01-01

    A greenhouse experiment was carried out to determine the mycorrhizal dependency of laurel (>Ocotea sp.). In order to do this, a completely randomized experimental design was used, with six treatments in a factorial array of 3 x 2 and five repetitions. The treatments involved a combination of three Phosphorus (P) levels in soil solution (0.002, 0.02 and 0.2 mg L-1) and two levels of mycorrhizal inoculation, either inoculated or non-inoculated with Glomus aggregatum Schenck and Smith. The leaf P content as a function of time was used as an output variable. Shoot dry matter, shoot P content, mycorrhizal colonization of roots, and mycorrhizal dependence were measured at harvest. The results indicated that the leaf P content increased significantly when using the mycorrhizal inoculation in laurel at P level 0.2 mg L -1, but not in the other P levels, on some of the sampling days. Shoot dry weight and total plant P content did not increase at all levels of soil available P. Mycorrhizal dependency of laurel reached 28%, which allows this species to be classified as moderately dependent on mycorrhiza.

    Por deferencia de la Junta Directiva de la Academia Nacional de Medicina y en especial de su Presidente el doctor Efraím Otero-Ruiz, tengo hoy el privilegio de dirigirme ante ustedes para hacer el elogio póstumo del Profesor Gonzalo Esguerra Gómez, y resaltar las virtudes que adornaron su personalidad atractiva y marcaron el rumbo de una vida dedicada por entero al servicio de sus semejantes.

    Son múltiples las distintas facetas que con el nombre de virtud pueden caracterizar a los seres humanos. Sin embargo, si nos remontamos a la concepción antigua de la Grecia clásica, es la virtud la calidad que hace a un hombre bueno, tanto en su carácter como en su mente. De allí la división explícita que hace Aristóteles de las excelencias de carácter o virtudes morales y las de la mente o virtudes intelectuales, entre las cuales incluye la sabiduría, la prudencia y la razón intuitiva que Santo Tomás llamó más tarde el entendimiento. De estas últimas, es la virtud de la prudencia, por corresponder a la conducta, las más relacionada con las morales de justicia, de valor y de temperancia.

    La implicación de estos conceptos es sencilla: un hombre puede alcanzar la excelencia y ser llamado bueno como científico o artista, pero la adquisición de estas virtudes no lo hace bueno como hombre, a menos que la prudencia, se agregue a las virtudes morales.

    Gonzalo Esguerra Gómez fué un hombre bueno y un hombre prudente. Se trazó como una directriz de su vida, la ética en sus pensamientos y en sus acciones y jamás se desvió del camino que se había trazado. De allí que su vida mirada con la perspectiva de lo ancho y de lo profundo se nos presente como un cuadro renacentista de Benozzo Gozzoli: todo está allí, sus aspiraciones, sus ilusiones, sus desencantos y sus realizaciones, todo nítidamente dibujado, sin sombras, sin vacíos, con los claros colores propios de su sensibilidad y los perfiles precisos de su

    Full Text Available Ocotea porosa seeds have strong tegument dormancy, recalcitrant behavior, low and irregular germination and that makes its natural propagation difficult. The aim of this study was to establish a protocol of regeneration of Ocotea porosa from somatic embryogenesis. Immature embryonic axes were inoculated on WPM culture medium supplemented with 2.4-D (200 μM combined or not with hydrolyzed casein or glutamine (0.5 or 1 g l-1, during 90 days. The repetitive embryogenesis was induced on medium with 2.4-D (22.62 μM combined with 2-iP (2.46 μM followed by transfer to culture medium with hydrolyzed casein or glutamine (1 g l-1 during 90 days. The maturation of somatic embryos was tested in culture medium containing NAA (0.5 μM and 2-iP (5; 10 and 20 μM. The highest percentage of somatic embryos induction (8.3% was observed in WPM culture medium containing 200 μM 2.4-D and 1 g L-1 hydrolyzed casein and the development of somatic embryos occurred indirectly. Repetitive somatic embryogenesis was promoted in WPM medium containing hydrolyzed casein or glutamine. However, the culture medium containing hydrolyzed casein promoted the maintenance of embryogenic capacity for more than two years. During the maturity phase, there was a low progression of globular embryos to cordiform and torpedo stages. The different ontogenetic stages of somatic embryos of Ocotea porosa were characterized by histological studies.

    This work describes the occurrence and contents of aporphinoids alkaloids in seedlings of Ocotea puberula from germination until 12 months old and in leaves from adult plants. Seedling leaves showed an alkaloids profile similar to leaves of adult plant. However, leaves in seedlings showed higher contents of the alkaloids boldine, dicentrine, leucoxine and isodomesticine when compared to adult plants. The alkaloids concentration in stems and leaves increased during the development of the seedlings, followed by a remarkable decrease of these compounds in roots. Cultivation in a seedling-nursery method is also described. (author)

    Full Text Available This article is based on the author’s research which presents and discusses for the first time, the work of three Uruguayan architects who worked with Le Corbusier. In the case of Carlos Gómez Gavazzo, the article comes to the conclusion that his training and previous interests prevailed over his exploration of Le Corbusier’s work. Gómez Gavazzo worked with Le Corbusier on the design for the quartier de la Marine in Algiers. When he returned to Uruguay he won second prize in the Diagonal Agraciada town planning competition. In this article the relationship between modern masks and traditional structures are discussed in the designs of the “Uruguayan Corbusier”.

    The genus Ocotea (Lauraceae) is distributed mainly in tropical and subtropical regions. Some species of this genus as O. puberula and O. quixos have been described in the literature, showing antibacterial activity. And Ocotea macrophylla showed anti-inflammatory activity with inhibition of COX-1, COX-2, and LOX-5. The purpose of this study was the phytochemical investigation of the plant species Ocotea notata from Restinga Jurubatiba National Park, Macaé, RJ, Brazil, and the search for antimycobacterial fractions and compounds. The crude extract was evaluated for antimycobacterial activity and presented 95.75 ± 2.53% of growth inhibition at 100 µg/mL. Then, it was subjected to a liquid-liquid partition and subsequently was chemically investigated by HPLC, revealing the major presence of flavonoids. In this process the partition fractions hexane, ethyl acetate, and butanol are shown to be promising in the antimycobacterial assay. In addition, ethyl acetate fraction was chromatographed and afforded two flavonoids identified by MS and NMR as afzelin and isoquercitrin. The isolated flavonoids afzelin and isoquercitrin were evaluated for their antimycobacterial activity and for their ability to inhibit NO production by macrophages stimulated by LPS; both flavonoids isoquercitrin (Acet22) and afzelin (Acet32) were able to inhibit the production of NO by macrophages. The calculated IC50 of Acet22 and Acet32 was 1.03 and 0.85 µg/mL, respectively.

    Várias espécies da família Lauraceae encontram-se em risco de extinção, devido ao alto valor comercial de suas madeiras e a consequente exploração das reservas naturais. Dentre elas, Ocotea porosa (imbuia, O. odorifera (canela-sassafras e O. catharinensis (canela-preta são de grande importância no Sul do Brasil, de onde são originárias. Estas espécies apresentam sementes recalcitrantes, o que dificulta sua regeneração natural. Alem disso, a propagação por meio de estaquia e enxertia apresenta limitações. Este trabalho teve por objetivo avaliar a germinação e multiplicação in vitro das canelas preta e sassafrás na presença de BAP e carvão ativado e a germinação e multiplicação in vitro de imbuia sob diferentes concentrações de sacarose no meio de cultura. Para as canelas preta e sassafrás foram avaliadas duas concentrações de NaClO na desinfestação de embriões (0,1 % e 0,5 %. Na fase de multiplicação, foi avaliado o efeito de BAP e carvão ativado. Para a imbuia, foi avaliada a influência da concentração de sacarose (30, 60, 90 ou 120 g.L-1 na introdução e multiplicação in vitro. A porcentagem de germinação foi superior a 85 % para as três espécies. Para a canela sassafrás, as melhores taxas de multiplicação foram obtidas na presença de 5 μmol.L-1 de BAP. Para a imbuia, a concentração de 60 g.L-1 de sacarose no meio proporcionou as maiores taxas de multiplicação.

    Mc ha conferido la Junta Directiva de la Academia el alto honor de tomar la palabra en esta noche, distinción que he aceptado con agrado ya que se me concede la oportunidad de hablar ante ustedes sobre la personalidad particularmente atractiva del profesor Esguerra Gómez quien fuera mi maestro de medicina y me distinguiera a través de muchos años con el valioso don de su amistad.

    Ya el académico Rueda Pérez se ha referido a los pormenores del descubrimiento de los rayos X en esa noche del 8 de Noviembre de 1895, en el salón 119A del Colegio Técnico de Wurzburg en donde funcionaba el laboratorio de Física cuyos ventanales dan hacia los jardines botánicos y al hoy llamado Círculo de Roentgen.

    Roentgen tenía en ese entonces 43 años y un bien cimentado prestigio científico. Había hecho estudios cuidadosos sobre el comportamiento de la materia y había sido por ejemplo el primero en demostrar, utilizando un termómetro de fabricación casera, que era más fácil calentar el aire húmedo que el aire seco. Otros aspectos de su trabajo dieron fuerte apoyo a la teoría unificada del magnetismo y la electricidad que había sido formulada hacia los años de 1870, por el físico matemático escocés James Maxwell.

  11. The Mexican Assimilation: Colombia in the 1930s - The case of Ignacio Gómez Jaramillo

    Full Text Available During the 1930s in Colombia, artists such as Ignacio Gómez Jaramillo, took Mexican muralism as an important part of their careers thus engaging with public art for the irst time in the country. In 1936, Gómez Jaramillo travelled to Mexico for two years in order to study muralism, to learn the fresco technique and to transmit the Mexican experience of the open-air-schools. Gómez Jaramillo returned to Colombia in 1938 and in 1939 painted the murals of the National Capitol. Although Gómez Jaramillo’s work after 1939 is well known, his time in Mexico has been barely studied and very few scholars have analyzed the artist’s work in light of his Mexican experience. While in Mexico, Gómez Jaramillo joined the LEAR (La Liga de Escritores y Artistas Revolucionarios with whom he crated the murals of the Centro Escolar Revolución. These murals depict politically engaged images that, apparently, little had to do with his more historical work back in Colombia. This text proposes a careful reading of the artist’s work at the CER and a rereading of the National Capitol murals in light of a more politicized vision.

    Comenzaba el año de 1928 cuando una tarde se presentó al Consejo de la Facultad de Medicina de la Universidad Nacional el Profesor Julio Aparicio para anunciar su retiro de la cátedra de Fisiología y candidatizar para ese cargo, al joven médico Dr. Alfonso Esguerra Gómez, quien lo había asesorado en París en la adquisición de un laboratorio para su
    cátedra; consideraba el dimitente que no había nadie en el país tan preparado como su candidato para dar un vuelco en la enseñanza de las ciencias básicas, sacándolas de la enseñanza netamente teórica y dándole un carácter más moderno, pragmático y experimental a la docencia.

    Muy afortunada fue la designación porque el novel profesor resultó que había heredado la facilidad de dicción y las dotes pedagógicas de su ilustre padre el Prof. Carlos Esguerra. Además de ello exhibió desde el primer momento un dinamismo realmente asombroso: en muy corto tiempo instaló, superando dificultades de toda índole, el laboratorio por él escogido y logró la colaboración de un grupo selecto de médicos jóvenes entre los cuales se destacaban Ramón Atalaya, Juan Pablo Llinás, Daniel Brigard Herrera, Ernesto asomo,

    Rhipicephalus (Boophilus) microplus is responsible for reducing animal welfare, causing a drop in productive performance and transmitting hemoparasites. The main strategy of tick control is application of synthetic acaricides. However, parasite resistance to these compounds is a major concern. Therefore, the acaricidal and repellent in vitro effect of the Ocotea elegans essential oil on larvae and adult females of R. (B.) microplus were evaluated. The larval packet test (LPT), larval repellency test (RT) and adult immersion test (AIT) were performed. The essential oil was analyzed by gas chromatography (GC/FID) and the structure of the oil's major constituent (92.2% sesquirosefuran) was elucidated by nuclear magnetic resonance. In the AIT, efficacy higher than 90% was detected from the concentration 25 mg/mL upward. In both LPTs performed after 48 h, only the 100 mg/mL concentration resulted in mortalities above 70%. On the other hand, the essential oil caused an average of 95.8% repellency from 0.78 to 100 mg/mL. The LC 50 in the two LPT (48 h) tests were 59.68 and 25.59 mg/mL, respectively. The LC 50 and LC 90 in the AIT were 4.96 and 17.37 mg/mL, and in the RT they were 0.04 and 1.24 mg/mL respectively. We conclude that the essential oil of O. elegans leaves has a significant acaricidal effect on engorged females and on larval repellency of R. (B.) microplus ticks, and can be a promising alternative for the control of this ectoparasite. Copyright © 2018. Published by Elsevier B.V.

  18. Enrique Gómez Carrillo a la defensa de Clarín

    Kronik, John W.

    2003-06-01

    Full Text Available Enrique Gómez Carrillo at the age of seventeen published in the Guatemalan newspaper El Imparcial in February 1890 a two-part article entitled «El último folleto de Clarín.» It is a review of the sixth of Leopoldo Alas's Folletos literarios, Rafael Calvo y el teatro español, in which the freshly minted critic defends Clarín in the most laudatory terms against the attacks of the Salvadorean writer Francisco Gavidia, a close friend of Rubén Darío, both of whom Clarín's apparently anti-American stance had offended deeply. With this forgotten article Gómez Carrillo unleashed a lively polemic, both for his impassioned praise of Clarín as a critic and as a fiction writer and for his acerbic, burlesque tone. In this respect, he echoed Clarín himself, who by this time had become one of the most widely read and hotly debated peninsular writers in Spanish America. Critics have documented the literary relations between Clarín and Gómez Carrillo after the latter's arrival in Madrid and after Clarín reviewed Gómez Carrillo's first book in 1892, but this obscure article, which is reprinted here, pushes the contact back two years and is a demonstration of the sincere and disinterested admiration that Gómez Carrillo felt for Clarín at a time when he owed him no debts.Se reproduce aquí un artículo desconocido, publicado en dos partes por Enrique Gómez Carrillo, a la edad de diecisiete años, en el periódico El Imparcial de Guatemala en febrero de 1890.

    1. An expedition to Salas y Gómez and Easter islands was conducted to develop a comprehensive baseline of the nearshore marine ecosystem, to survey seamounts of the recently created Motu Motiro Hiva Marine Park (MMHMP) – a no-take marine reserve of 150 000 km2 – and to compare these results with Easter Island where the marine ecosystem is similar but has no marine protection. 2. Live coral cover was surprisingly high at both Easter Island (53%) and Salas y Gómez (44%), especially considering their sub-tropical location, high wave energy environments, and geographic isolation. 3. Endemic and regionally-endemic species comprised 77% of the fish abundance at Easter Island and 73% at Salas y Gómez. Fish biomass at Salas y Gómez was relatively high (1.2 t ha-1) and included a large proportion of apex predators (43%), whereas at Easter Island it was almost three times lower (0.45 t ha-1) with large predators accounting for less than 2% of the biomass, despite good habitat quality. 4. The large cohort of small sharks and the absence of larger sharks at Salas y Gómez suggest mesopredator release consistent with recent shark fishing. The fish fauna at the seamounts between Easter Island and Salas y Gómez, outside of MMHMP, harboured 46% endemic species, including a new species of damselfish (Chromis sp. nov.) and probably a new species of Chimaera (Hydrolagus). Numerous seamounts adjacent to Salas y Gómez are currently not included in the MMHMP. 5. This expedition highlights the high biodiversity value of this remote part of the Pacific owing to the uniqueness (endemicity) of the fauna, large apex predator biomass, and geographic isolation.

    Woods, as other materials, are susceptible to alterations in their internal structure because of physical, chemical or biological agents. Wood can be considered a natural composite with high strength capacity provided by cellulose and hemicellulose agglutinated by lignin, substances with very distinct structures. In several applications, the use of radiation can be interesting, once it turns wood more resistant to biological demand. The application of gamma radiation in work of arts and archaeological artifacts preservation began in 1970, in France.

    Woods, as other materials, are susceptible to alterations in their internal structure because of physical, chemical or biological agents. Wood can be considered a natural composite with high strength capacity provided by cellulose and hemicellulose agglutinated by lignin, substances with very distinct structures. In several applications, the use of radiation can be interesting, once it turns wood more resistant to biological demand. The application of gamma radiation in work of arts and archaeological artifacts preservation began in 1970, in France. By other side, no changes in wood properties and no remaining radioactive waste were desirable.

    Full Text Available Ocotea porosa (Ness Barroso (Lauraceae, a typical tree of the southern Atlantic Forest in Brazil, was heavily exploited for timber in the last century. With the aim of examining the status of the remaining populations, we surveyed five forest fragments in the state of Paraná, in southern Brazil, and evaluated whether disturbances caused by selective logging and fragmentation were related to population structure of O. porosa. We assessed demographic aspects related to tree density, size hierarchy and individual allometry, correlating those parameters with fragment structure variables (fragment size, isolation and logging level. We found that, although all populations occurred in low densities (60-440 individuals ha−¹, the number of adults was significantly lower in the smaller and most disturbed fragments (13 and 35 individuals ha−¹, respectively. We did not detect changes in allometric relationships among individuals in the five populations studied. However, we found that populations in more heavily disturbed areas presented lower size hierarchy (i.e., less dominance of larger trees than did those in undisturbed areas, suggesting that selective logging affects the population structure of O. porosa, possibly affecting the rates of reproduction and fecundity, which may ultimately increase the probability of local extinction.

    Romero, Cira

    2014-12-01

    Full Text Available The literary work of Gertrudis Gómez de Avellaneda was devoted mostly to three genres: poetry, narrative and drama. Nevertheless, there remain some important but less considered facets of her writing interests, such as her remarkable work as a columnist —where we can find texts later judged real essays— and as a literary critic. Among the latter I highlight her brief, but no less important, role as a prologue writer, dedicated absolutely to Cuban authors of varying significance: the Countess of Merlín, Luisa Pérez de Zambrana, Teodoro Guerrero and Ángel Mestre. Our contribution analyses the diverse foundations that support these texts, written in different moments between 1844 and 1865, where her literary and civic obsessions, and the theme of the “gender mark” that pervades her works, are exposed.La obra literaria de Gertrudis Gómez de Avellaneda se cumplió fundamentalmente en tres géneros: poesía, narrativa y teatro. Quedan a su favor otros flancos importantes y poco estudiados de su labor, tales como su apreciable quehacer como articulista en trabajos devenidos, a veces, en verdaderos ensayos, y como crítica literaria. En esta última coloco su breve, pero no menos relevante servicio como prologuista, ejercido siempre sobre obras de autores cubanos de mayor o menor relevancia: la condesa de Merlín, Luisa Pérez de Zambrana, Teodoro Guerrero y Ángel Mestre. Nuestra propuesta valora los presupuestos de diverso carácter expuestos en esos trabajos, escritos en diferentes momentos entre 1844 y 1865, donde quedan reveladas sus propias inquietudes literarias, cívicas y también la marca de género, tan presente en el conjunto de su obra.

    Full Text Available The potential economic and environmental benefits brought by bromeliads production are significant. It is noteworthy that the high degree of degradation of some ecosystems as the Atlantic forest involve reduction of these species. This factor has been worsened by the elevated degree of endemism of these plants, e.g. Aechmea costantinii (Mez L. B. Sm., which is a high ornamental potential bromeliad but understudied. Thus, the present research aimed to characterize physical and morphological features of A. costantinii fruit and seeds, describing the different stages of post - seminal development, as well as evaluating seed germination behavior with respect to temperature and light. For this purpose, we used fruit and seeds freshly harvested from an Atlantic Forest fragment, located in the city of Maceió, Alagoas State, Brazil. Tests were carried out under a completely randomized design, in a 6x4 factorial scheme (temperature x light with four replications of 25 seeds. The polyspermic fruit are of tricarpellate/triloculate type and originated from inferior ovary, containing an average of 73 elliptical and mucilaginous seeds with basal embryo. The germination is epigeal - type and occurs in a great intensity and high speed at 35 °C, regardless light presence or quality.

  1. A new interpretation of «El cacique de Turmequé» by Gertrudis Gómez de Avellaneda

    María Luisa Pérez Bernardo

    2014-12-01

    Full Text Available Gertrudis Gómez de Avellaneda is remembered for her controversial and progressive beliefs. She established a reputation early in her career as a talented writer whose unconventional behavior was as well known as her works. During her lifetime, Avellaneda enjoyed literary and commercial success in several genres, including poetry, drama, essays, and lengends. In the legend «El cacique de Tumequé» written in 1860 and published in 1871, Gertrudis Gómez de Avellaneda re-interpretes Juan Rodríguez Freyle‘s El carnero o conquista y descubrimiento del Nuevo Reino de Granada (1636-1638. Through this essay it will be displayed how Avellaneda with «The cacique of Turmequé» presents a vision of Nueva Granada distinct to that of the chronicler Juan Rodríguez Freyle. In this way, the female writer manipulates historical time, to propose to the Spanish public of the 19th century another version of the conquest, one that was not that of the victors, but of the vanquished; distancing herself from the dominant discourse of her time. In «El cacique de Tumequé», Avellaneda challenges the political power of the colonial era that positioned women as inferior human beings. In her narrative, she breaks away from the established order, especially against the misogynist remarks from El carnero, a chronicle that consistently criticized and ridiculed women. Gómez de Avellaneda‘s work deconstructs the social and political institutions that emphasized the idea that women were intellectually subordinate. Moreover, in «El cacique de Turmequé» she defendes the dignity of the indigenous population, by reaffirming their integrity and liberty in the colonial society.

    2015-01-01

    Full Text Available Commercial plantations of Ocotea porosa available for studying are scarce and therefore should be used as a source of information to establish the potential for management of the species in plantations, even if these evaluations were not been held along the stand development. The recovery of the historical growth of these stands to optimize the management plans is possible by dendrochronology and by the analysis of morphometric and dendrometric data. The aim of this study was to use stand analysis tools, combined with the dendrochronological studies, to recover and to systematize the development of unmanaged stands. The study was conducted in an unmanaged stand of Ocotea porosa , with with 44 years of age in Rio Negro, PR state, in a UFPR research station. Growth inferences recovered by dendrochronology and the competition by the application of methodologies such as rate of coverage and crown cover rate showed consistent results in the analysis of population, indicating the need for a first thinning near 12 years old. Due to the small number of sampled trees, the results do not allow any definitive generalization. However, they are consistent to establish an analysis protocol for unmanaged stands of Ocotea porosa or other species.

    Full Text Available The aim of the study was to establish a DNA isolation protocol Nectandra megapotamica (Spreng. Mez., able to obtain samples of high yield and quality for use in genomic analysis. A commercial kit and four classical methods of DNA extraction were tested, including three cetyltrimethylammonium bromide (CTAB-based and one sodium dodecyl sulfate (SDS-based methods. Three drying methods for leaves samples were also evaluated including drying at room temperature (RT, in an oven at 40ºC (S40, and in a microwave oven (FMO. The DNA solutions obtained from different types of leaves samples using the five protocols were assessed in terms of cost, execution time, and quality and yield of extracted DNA. The commercial kit did not extract DNA with sufficient quantity or quality for successful PCR reactions. Among the classic methods, only the protocols of Dellaporta and of Khanuja yielded DNA extractions for all three types of foliar samples that resulted in successful PCR reactions and subsequent enzyme restriction assays. Based on the evaluated variables, the most appropriate DNA extraction method for Nectandra megapotamica (Spreng. Mez. was that of Dellaporta, regardless of the method used to dry the samples. The selected method has a relatively low cost and total execution time. Moreover, the quality and quantity of DNA extracted using this method was sufficient for DNA sequence amplification using PCR reactions and to get restriction fragments.

The growth data were tested with three mathematical equations, for the adjustment of diameter and commercial volume without bark. The quadratic equation resulted as a more efficient model, for the CV and DBH estimate, adjusted in function of the age of the trees. The Backman equation was selected for the CAI and for the f estimate. The values were determined in function of the DBH to facilitate practical application. The commercial form factor varied from 0,40 for a DBH of 5 cm to a maximum value of 0,85 for a DBH from 22 to 32 cm, decreasing up to 0,78 at 51 cm of DBH, between the ages of 10 and 100 years. The average annual increment in percentage of the commercial volume varied from 17,48% for 10 years to 1,33% for 100 years of age. The species presented a good growth potential, that associated with management practices can increase its productivity.

    2006-10-04

    The chemical composition of the essential oil obtained by steam distillation of the floral calyces of Ocotea bofo Kunth (Lauraceae) was studied by means of GC, GC-MS, and 1H, 13C, and bidimensional NMR (COSY, HSQC, HMBC). Twenty-five constituents were identified, and estragole (48.7%), alpha-phellandrene (19.6%) and sabinene (10.4%) were found to be the major components. Antimicrobial activity against six aerobic bacteria and five yeasts and antioxidant activity performed by photochemiluminescence (PCL), 1,1-diphenyl-2-picrylhydrazyl (DPPH), and beta-carotene bleaching assays are reported. The oil showed fair inhibiting properties against bacteria and a good inhibition against most yeasts. Its radical scavenging and chain-breaking antioxidant properties were comparable to or better than those provided by synthetic controls. Particular emphasis has been given to the use of NMR as a fast and reliable tool to discriminate O. bofo essential oil from other commercial anethole- and estragole-rich oils, namely, Illicium verum, Foeniculum vulgare, and Artemisia dracunculus.

  13. Authority, Power and Reason of State in the Theater of Antonio Enríquez Gómez

    Manuel Calderón Calderón

    2017-06-01

    Full Text Available Comedies of political content written by Antonio Enríquez Gómez reflect, through the analysis of its four recurring themes —the dichotomy between law and power, the reason of state, the law enforcement from a political point of view and forgiveness—, the outlines of the nascent Leviathan or modern state. Although the patriarchal relationship between the Monarch and his people is based on a iusnaturalist conception, love should be subject to the effectiveness in the exercise of power. The characters in this theatre sometimes hesitate between Aristotelian-Thomistic rationalism and Machiavellian-Hobbesian reason of state and, on other occasions, they oppose the people’s strength, risk and will to the divine reason of Law. In the context of the Hispanic Monarchy crisis, Enríquez Gómez’s critics are not limited to Government representatives and civil servants, but also include the Church and common people (Third State.

    Aun cuando transcurrió algún tiempo, el órgano de publicidad de nuestra corporación registra en esta entrega tan lamentable suceso que afecta a la sociedad bogotana y a la ciencia médica, no sólo del país sino también de América, en donde su nombre brilló en la ciencia médica de la radiología.

    A continuación complacemos a muchos médicos quienes desean conocer parte de la biografía del ilustre médico.

    El profesor Esguerra nació en Bogotá el 24 de enero del año de 1902 y falleció el 21 de diciembre de 1989; obtuvo el título de médico cirujano de la Facultad de Medicina de la Universidad Nacional en el año de 1927, Y a continuación emprendió estudios de postgrado en radiología, ciencia a la cual dedicó todo su saber y actividad profesional.

    El profesor Esguerra, tanto por la línea paterna como materna, tuvo progenitores vinculados por la familia a los. más destacados médicos de la capital del país: los doctores Carlos Esguerra y Proto Gómez. En 1934 fue nombrado por concurso de méritos y títulos, profesor de electro-radiografía de la Facultad de Medicina de la Universidad Nacional.

    Durante el período 1937-1947 fue director de la Clínica Marly; su padre, el doctor Carlos Esguerra, a su regreso de Europa en el año de 1903, puso en ejecución la peligrosa idea, por aquella época, de fundar una clínica, lo cual realizó al adquirir para tal fin una quinta situada por el camino de Chapinero, la que perteneció a un ciudadano francés que la había bautizado con el nombre de Marly, en recuerdo de la pintoresca casa de recreo de los Reyes de Francia, cerca de Versalles.

    El profesor Gonzalo Esguerra durante todo el tiempo de su eficaz y ético ejercicio profesional lo hizo en la Clínica de Marly, hasta su fallecimiento, dándole prestigio a la institución.

    Se puede considerar al profesor Esguerra como el fundador de la radiología en Colombia. Estableció en la capital la

    énez importaron educadores y científicos europeos para establecer un moderno sistema educativo nacional. Henri Pittier reside en Costa Rica durante 17 años en los que enseña en el Liceo de Costa Rica, establece el Instituto Meteorológico Nacional, dirige el Instituto Físico Geográfico y el Herbario Nacional e impulsa el establecimiento del Museo Nacional como centro de investigación y exhibición de la historia natural del país. Pittier deja Costa Rica en 1905 para recorrer las Américas como botánico del Ministerio de Agricultura de los Estados Unidos durante 14 años. Se establece finalmente en Venezuela como funcionario del Ministerio de Relaciones Exteriores en 1919 y allí dirige y funda varias instituciones públicas y privadas, entre ellas el Parque Nacional que más tarde llevaría su nombre y el Herbario Nacional, hoy Instituto Botánico. En las décadas finales de su vida lleva a cabo la monumental obra de estudiar y clasificar más de 30.000 plantas en Venezuela.Pittier viajó ampliamente por Costa Rica y las observaciones de sus viajes, publicadas en diversos medios, incrementaron sustancialmente el conocimiento de la geografía y biología de Costa Rica. El ensayo que aquí reproducimos recoge observaciones de uno de esos viajes. En particular, captura los recuerdos de un centenario nicoyano, José Silverio Gómez, fallecido en 1904 a la edad de 103 años. Aunque esos recuerdos aportan valiosa información sobre la vida y el entorno natural de Nicoya del Siglo XIX, nuestro interés fundamental en esta crónica es la observación del sabio Pittier de que los moradores de la zona disfrutan del privilegio de una larga vida: “…en todas mis peregrinaciones por estas tierras no he encontrado otro rincón cuyos habitantes estén bendecidos con tal abundancia de años” escribe el sabio. Aunque la percepción de Pittier es puramente anecdótica no deja de tener interés como antecedente de los estudios que, basándose en datos puros y duros, han mostrado que

    Full Text Available In 1928, José Royo Gómez mentioned the find of “two teeth similar to those of theropod dinosaurs from the Secondary” in the Eocene of Llamaquique (Oviedo Basin, Asturias. Royo Gómez was aware of the interest of the discovery, “because they would be the youngest remains found of these gigantic reptiles”. According to the hitherto unpublished documents preserved in the Archives of the Museo Nacional de Ciencias Naturales in Madrid, Royo Gómez photographed five teeth from Llamaquique in April 1932, which he regarded as belonging to theropods. The whereabouts of this material is currently unknown. However, the revision of the Llamaquique collection in the above mentioned museum has allowed to recover one labiolingually compressed and serrated tooth (ziphodont condition. We reject here that the tooth belongs to a theropod, and we assign it to a Mesoeucrocodylia indet. This is the first mention of the discovery of ziphodont crocodyliforms in the Paleogene of Asturias.

    En 1928, José Royo Gómez informó del hallazgo de “dos dientes idénticos a los de los Dinosaurios terópodos del Secundario” en el Eoceno de Llamaquique (Cuenca de Oviedo, Asturias. Royo Gómez era consciente del interés de este descubrimiento, “pues serían los restos más modernos que se conocerían de estos gigantescos reptiles”. Según la documentación conservada en el Archivo del Museo Nacional de Ciencias Naturales en Madrid, hasta ahora inédita, Royo Gómez fotografió en abril de 1932 cinco dientes de Llamaquique que él consideraba pertenecientes a terópodos. Este material se encuentra actualmente en paradero desconocido. No obstante, la revisión de la colección paleontológica de Llamaquique en el mencionado museo ha permitido recuperar un diente comprimido lateralmente y provisto de carenas denticuladas (condición zifodonta. Se descarta que el diente pertenezca a un terópodo, asignándose a un Mesoeucrocodylia indeterminado. Se trata de la

    Laura Scarano

    2014-06-01

    Ramón Gómez de la Serna wrote a peculiar autobiography called Automoribundia, which embraces sixty years (1888-1948. From Spain to his exile in Argentina, and confronting the ambiguities of his political posture toward the franquista regime, this controversial avant-garde work distorts the conventions of the autobiographical genre to show instead an ars moriendi. We will focus on the singularity of this “automoribundia” machine, that settles the basis of his heterodox reading pact.

    2016-12-01

    Full Text Available Entre 1934 y 1952 el Arquitecto Carlos Gómez Gavazzo desarrolla un enfoque de las problemáticas rurales de Latinoamérica y en particular de nuestro país. Ampliando la escala de las preocupaciones, pasa de problematizar la unidad de hábitat familiar del campo a una completa teoría sobre el modo de ordenar la totalidad del territorio productivo rural. Este decurso va acompañado de una formulación precisa de un imaginario radicalmente alternativo al habitual de los trabajadores rurales. Esta tesis busca probar que las condiciones del hábitat propuestas para el ámbito conformarían una red de localizaciones de pequeña escala, de alta densidad y equipada con buen nivel de servicios, es decir, un imaginario netamente urbano para la vida en el campo. Para ello se analizará el proceso de construcción de la problemática rural y se tomará por caso el proyecto para el centro colónico de Chapicuy de 1953

    Full Text Available This study aims to determine the floral visitors and potential pollinators of Aechmea constantinii (Mez L. B. Sm. (Bromeliaceae, a bromeliad endemic to the Brazilian Northeast Atlantic Rainforest. Reproductively-active individuals were observed systematically and their visitors were recorded and determined. The main recorded fl oral visitors were Glaucis hirsutus, Phaethornis ruber and Phaethornis pretrei (hummingbirds which executed frontal functional floral visits in which they touched the parts of the fl owers. Visits of Plebeia flavocincta, Plebeia sp., Trigona spinipes and Euglossa cordata (bees and Talides sergestu and Strymon ziba (butterflies were also recorded. In addition, two ants (Hymenoptera, Insecta, Formicidae were identifi ed in activity on the fl oral scapes and flowers of the studied bromeliad. The suggestion is made in the study that the A. constantinii is pollinated by hummingbirds since these birds executed direct frontal visits to the fl owers, touching reproductive structures. The identification of pollen on the bodies of bees and butterflies, as well as the contact executed by visitors, with the stigma of the visited flowers, offered an indication that these species may exert an influence as secondary pollinators of Aechmea constantinii.

As miniestacas foram obtidas de mudas de regeneração natural com aproximadamente um ano de idade e modeladas com 5 cm de comprimento e 0,4 - 0,6 mm de diâmetro. O experimento foi conduzido em casa de vegetação, com sistema de nebulização intermitente regulada em 20 segundos para aspersões com intervalos de 20 minutos. Como substrato foi utilizado areia lavada. Semanalmente foram feitas aplicações de fertilizante foliar e fungicida. O experimento foi delineado em cinco blocos inteiramente ao acaso, com cinco tratamentos (0, 300 ppm, 600 ppm, 1200 ppm e 2000 ppm de AIB com 25 miniestacas/tratamento, totalizando 125 miniestacas no experimento.

    Mauricio Galindo Hurtado.

    2000-06-01

    Full Text Available Sobresaliente en el panorama intelectual colombiano es la figura de Nicolás Gómez Dávila. Este escritor sabanero es tal vez la única voz que, en forma explicita y magistral, se propuso desmenuzar el pensamiento occidental asumiendo la postura del reaccionario. Gómez Dávila deja, al morir, un libro en cinco etapas, colección de aforismos qúe insiste en llamar escolios, en los cuales discurre sobre la filosofía, la moral, la estética, la historia y la literatura de más de dos mil años de civilización grecolatina. La obra de Gómez Dávila posee la convicción dogmática del reaccionario que condena con juicios enfáticos las glorias del hombre "moderno". Hay allí ecos de una visión hispánica de Contra Reforma que influyó no poco en buena parte de las elites colombianas. Mas es también un llamado a la sensibilidad y a la belleza, un recordatorio que más allá de un conocimiento racional y científico, está la dimensión de la persona humana que ningún sistema puede abarcar. Férreo defensor de un libre albedrío enmarcado en un exigente universo moral, su voz incita al despliegue máximo de la inteligencia, inigualable herramienta para alzar vuelo sobre realidades pedestres.

The paper presents hypotheses on this puzzling and perhaps erroneous fact.Se realiza la presentación y análisis de unas breves notas inéditas del humanista Alvar Gómez de Castro, conservadas en el manuscrito 7896 de la BN, sobre cinco conocidas inscripciones. Su interés reside en que constituyen las primeras referencias de cada una de ellas y aportan datos útiles para la historia de las piezas. Pero lo más llamativo es que se presenta una inscripción en S. Román de Hornija con idéntico texto al de la inscripción de S. Juan de Baños. En este trabajo se apuntan algunas hipótesis sobre tan desconcertante y quizás errónea noticia.

  16. «Dios hará inquisición de vuestros juicios»: Antonio Enriquez Gómez' Search for Justice

    Rose, Constance H.

    Full Text Available One theme uniting the work of Antonio Enríquez Gómez (1600-1663, a Spanish Marrano who resided in France for many years, was his search for justice— personal, earthly and divine. By examining two of his plays and two treatises, above all the comically sardonic Inquisición de Lucifer y Visita de todos los diablos (n.d., a text recently discovered in Amsterdam, it is possible to see that this author bases his thesis, in part, on two geographical locations: «Peralvillo», which symbolizes the miscarriage of earthly justice, and «el valle de Josafá», where divine justice will prevail.

    Un tema que une la obra de Antonio Enriquez Gómez (1600-1663, un marrano español que vivió un largo exilio en Francia, es la búsqueda de la justicia: personal, terrestre y divina. Al examinar dos comedias y dos tratados suyos, sobre todo su Inquisición de Lucifer y Visita de todos los diablos (s. f., un texto recién descubierto en Amsterdam, se puede ver cómo el autor desarrolla su tesis empleando dos topónimos antitéticos: «Peralvillo», que muestra la falta de justicia en este mundo, y «el valle de Josafá», donde Jehová dispensará la justicia divina y castigará a los enemigos de su pueblo, el pueblo judío.

    Full Text Available From the beginning of the 19th century on, several small sampling trips as well as large national and international scientific expeditions have been carried out to Easter Island (EI and Salas y Gómez Island (SGI. The objective of this study is to compile, synthesize and analyze published information about the biodiversity of macroalgae, macroinvertebrates and fishes associated with EI-SGI, updating the state of knowledge and making it available for the development of conservation plans. We searched all the available sources of information, such as scientific publications, scientific expeditions, fisheries data, technical reports, books, databases and online sources. We found 964 species reported within EI-SGI (143 species of macroalgae, 605 macroinvertebrates and 216 fishes, the majority for EI (923; for SGI 171 species have been reported. Species richness has increased over time, without leveling off, as sampling effort increases. However, seamounts and hydrothermal vents have been poorly studied in Chile's Exclusive Economic Zone (EEZ. A high percentage of endemism has been determined for the majority of the taxonomic groups, with mollusks and poriferans exhibiting the highest levels of endemism (33 -34%. Thus, the Rapanuian biogeographic province can be clearly identified, but information to differentiate between EI and SGI, and direct island-specific conservation efforts, is lacking. Nevertheless, the most vulnerable yet unprotected habitats (hydrothermal vents, higher diversity of seamounts size are located towards the western limit of the EEZ.

    En esta sesión solemne de la Academia Nacional de Medicina, para recordar al ilustre académico Gonzalo Esguerra Gómez sólo me referiré en estos 15 minutos a algunas facetas de su prodigiosa personalidad, en especial su aspecto humano y su labor como gran docente y escritor médico. Su característica principal fué su gran caballerosidad, siempre afable, cordial, listo a prestar cualquier servicio y todo lo hacía con entusiasmo y optimismo.

    Su orden era proverbial y esa cualidad fue uno de los motivos para su éxito profesional; exacto en sus compromisos y si se presentaba algún inconveniente lo informaba con anterioridad, todo esto renejaba su pulcritud y educación exquisita.

    Mi primer recuerdo del académico Gonzalo Esguerra Gómez se remonta a mi niñez: era yo estudiante de primaria en el Colegio de la Presentación de Bogotá en los finales del año 20. Por alguna novedad dental, con sospecha de compromiso maxilar, mi tío el médico doctor Guillermo A1bornoz-López, famoso anestesiólogo de la Casa de Salud de Peña y más tarde de la Clínica del gran cirujano Pompilio Martínez, resolvió en asocio del doctor Tiberio Rojas, (antiguo académico clínico de gran renombre, solicitar al doctor Esguerra Gómez una radiografía de su pequeño paciente; grande fue mi asombro verme rodeado de máquinas muy extrañas que producían leve ruido de tipo ventilador y todo este examen fue sin dolor alguno.

    Nos unía a las dos familias, Albornoz-Plata y Esguerra Gómez un lazo familiar lejano pero de marcado sabor emocional y siempre de adm iración por el joven radiólogo recién llegado de Europa y que había instalado su consultorio en la Clínica de Marly; sus parientes muy cercanos, la familia Esguerra Plata (Domingo, Lola de Dupuy, Cristina y Josefina, eran las primas de mi madre, María Plata-Arroyo de Albornoz, que con frecuencia se visitaban y se comentaba con entusiasmo sobre este notable y exitoso radi

    2012-10-01

    Full Text Available La obra de Pedro Gómez Valderrama (Bucaramanga, 1923 – Bogotá, 1992 es uno de los más notables ejemplos de recreación de la estética visual y de la imagen en la literatura colombiana del siglo XX. Este artículo explora el problema de las relaciones interartísticas en sus obras a través de estrategias de intertextualidad y de extrapolación. Se presenta, además del problema retórico de la descripción de la imagen artística en la obra literaria, una revisión del tópico artístico en la obra del escritor y su evolución a través de su carrera. Tal planteamiento se vincula con una hipótesis: la preponderancia de la obra de arte como hecho presente en las obras literarias enfocadas en lo visual.

  2. Determinants of scientific output: an in-depth view of the productivity of tropical botanist and conservationist, Luis Diego Gómez Pignataro

    Julián Monge-Nájera

    2010-12-01

    Full Text Available Bibliometric studies have found that male researchers have their greatest productivity around the age of 40, that female researchers produce less than their male colleagues, that incentives for collaboration are slow to affect productivity and that, just like humans, research institutes become larger, less productive, more expensive to maintain and less able to raise money as they grow old. Almost invariably, these conclusions come from statistical studies of large numbers of European and American scientists, and there are practically no studies about tropical researchers. We present an in-depth analysis of the productivity of an internationally recognized tropical botanist and conservationist, Luis Diego Gómez Pignataro, based on the totality of his published work and on our own knowledge, as co-workers and friends, of the life frame in which that scientific output was produced. His life output departs from the expected pattern in that he had the highest productivity before reaching the expected peak productivity age, and that when he reached it his productivity fell and never recovered. Furthermore, marriage did not produce the expected fall in productivity. A close analysis of his life indicates that in the middle of his career he switched to intense teaching and conservation activities, and this better explains why his output of scientific research articles was low afterwards. This switch may occur in other tropical scientists. Rev. Biol. Trop. 58 (4: 1093-1114. Epub 2010 December 01.

    Full Text Available The Chilean oceanic islands Easter Island (Rapa Nui and Salas y Gómez Island (Motu Motiro Hiva have received little attention with regards to basic marine mammal investigations. Here we review and update available information on the status of marine mammals in this area from different sources, including published accounts, local interviews and two recent expeditions. We also provide detailed accounts for each confirmed family or species, including historical data from published archaeological studies and whalers' logbooks from the 18th to the 20th centuries. Results indicate that a total of five marine mammal families (Balaenopteridae, Physeteridae, Ziphiidae, Delphinidae and Phocidae have been confirmed within the study area, representing two mammalian orders (Cetartiodactyla and Carnivora. Within these, twelve species are known to occur: blue whale (Balaenoptera musculus, unidentified minke whale (Balaenoptera bonaerensis or B. acutorostrata, humpback whale (Megaptera novaeangliae, sperm whale (Physeter macrocephalus, Cuvier's beaked whale (Ziphius cavirostris, Blainville's beaked whale (Mesoplodon densirostris, false killer whale (Pseudorca crassidens, unidentified pilot whale (Globicephala sp., bottlenose dolphin (Tursiops truncatus, common dolphin (Delphinus sp., southern elephant seal (Mirounga leonina and leopard seal (Hydrurga leptonyx. We discuss the implications of some of most noteworthy records and make a plea for further studies to improve our knowledge of these top predators in one of the most isolated places in the world.

  6. En los muros del Palacio: Pedro Nel Gómez en el imaginario social en Medellín, 1930-1950

    Juan Carlos Gómez

    2013-07-01

    Full Text Available Durante la década de 1920 apareció en Latinoamérica una serie de vanguardias culturales que cuestionaron la realidad nacional de sus países buscando cambios en la estructura social y política. Los políticos liberales colombianos, en su intento por llegar al poder, reconocieron en ellas diferentes ideas que influyeron en su desarrollo político. Con las reformas de Alfonso López Pumarejo se buscó un acercamiento con los artistas para que estos desarrollaran una tipología de arte en la que se involucrara a la sociedad y así ésta tomara conciencia de su historia e idiosincrasia. Bajo estos lineamientos Pedro Nel Gómez fue contratado para decorar el Palacio Municipal de Medellín con diferentes murales al fresco que cumplieran este propósito. El artista presentó nueve frescos que despertaron polémica debido al llamado de conciencia social que realizó al retratar los principales problemas de su país, situación que no solo le ganó el apelativo de socialista sino que años más tarde lo llevó a la censura. Con este texto se pretende interpretar esos murales como fuente de conocimiento histórico y ver en ellos los problemas sociales de la Colombia de los años treinta expresados por el artista desde su pensamiento socialista e influencia marxista.

  7. Biological oceanography, biogeochemical cycles, and pelagic ecosystem functioning of the east-central South Pacific Gyre: focus on Easter Island and Salas y Gómez Island

    Peter von Dassow

    2014-10-01

    Full Text Available The Exclusive Economic Zone of Chile defined by Easter Island and Salas y Gómez Island is in the South Pacific Sub-tropical Gyre (SPSG, putting it at the center of the most oligotrophic and biomass poor waters in the world. Only 10 biological oceanographic expeditions have entered this zone in 105 years (19052010. We review key aspects of the plankton ecosystem and biogeochemical function relevant for the understanding of and conservation planning for marine environments. Plankton production is limited by lack of dissolved inorganic fixed nitrogen, not phosphorous. Higher organic nitrogen levels might be biologically unavailable. Short-term experiments suggested iron is not limiting, yet iron still likely limits nitrogen fixation, and thus production, at longer time scales, as the presence of nitrogen-fixers is exceptionally low compared to other ocean gyres. Plankton function is dominated by the smallest unicellular organisms, picoplankton (<3 μm in diameter. The SPSG represents a center of high biodiversity for picoplankton, as well as heterotrophic organisms such as tinntinids, siphonophores, and possibly amphipods, although data for key zooplankton, such as copepods, are lacking. Many groups exhibit negative relationships between diversity and total plankton biomass. High diversity might result from dispersal from a very large metacommunity and minimal competition within functional groups. Whether an island-mass effect causes a real or apparent increase in plankton biomass around Easter Island must be confirmed by high-resolution sampling in situ. Long-term threats to the planktonic ecosystem may include climate change-enhanced ocean stratification and plastic marine debris accumulation. Finally, priorities for future research are highlighted.

Cette attitude paradoxale, de la part de quelqu'un qui, par esprit imprégné d'humanisme et par souci de réformer la mentalité du clergé à travers ses lectures, a pour but le retour le plus fidèle aux texte-sources de la foi, s'explique par l'influence de l'érasmisme, et par la souscription, tout à fait compatible, de notre auteur à une certaine sacralisation de la poésie.

The main recorded fl oral visitors were Glaucis hirsutus, Phaethornis ruber and Phaethornis pretrei (hummingbirds which executed frontal functional fl oral visits in which they touched the reproductive parts of the fl owers. Visits of Plebeia fl avocincta, Plebeia sp., Trigona spinipes and Euglossa cordata (bees and Talides sergestu and Strymon ziba (butterfl ies were also recorded. In addition, two ants (Hymenoptera, Insecta, Formicidae were identifi ed in activity on the fl oral scapes and fl owers of the studied bromeliad. The suggestion is made in the study that the A. constantinii is pollinated by hummingbirds since these birds executed direct frontal visits to the fl owers, touching reproductive structures. The identifi cation of pollen on the bodies of bees and butterfl ies, as well as the contact executed by visitors, with the stigma of the visited fl owers, offered an indication that these species may exert an infl uence as secondary pollinators of Aechmea constantinii.

    Full Text Available The article by Manuel Gómez-López et al., 2010 was read with interest by student members of Cardiff University's newly formed Sports and Exercise Medicine Society. As medical students we, more than most, are aware of the long term effects that a sedentary lifestyle may bring and its impact on a healthcare system such as ours in the United Kingdom (UK.We found the results of the study intriguing, particularly regarding the 'external barriers-lack of time' category as an important factor in not participating in sports. In the UK there is one afternoon every week which is set aside purely for sporting activities, providing the time to train and compete against other universities. Furthermore, UK universities on the whole offer more advanced and diverse facilities than those available to people at school, whilst there is also a greater number of sporting and exercise opportunities for people to partake in. University is potentially one of the best times in life to expand one's horizons and spend time enjoying the various extra-curricular activities that there is on offer, hence it is crucial that any perceived barriers to this are broken down to allow implementation of a healthy routine. Physical activity has been shown to decrease psychosocial stress and cardiovascular mortality (Milani and Lavie, 2009, something that would surely be considered positive if a sedentary individual were contemplating regular exercise.As future doctors we are concerned about an obesity epidemic that is only becoming more severe. Much of adult obesity has its roots in childhood (Sinha and Kling, 2009 and in modern times many children progress to university and further education. With students as the next generation of parents and working people, there should be a clear focus, especially across the developed world, on improving involvement in physical activities in the hope of decreasing prospective morbidity and the strain this brings to each nation's health service

  4. Topos města v románech Gómeze de la Serny. Mezi kosmopolitismem a tradicí // The topos of the city in Ramón Gómez de la Serna. Between cosmopolitism and tradition

    Marcela Vrzalová Hejsková

    2015-04-01

    Full Text Available This article deals with the role of the literary topos of the city and its importance in the Ramón Gómez de la Serna’s novels. According to the Daniela Hodrová’s typology we attempt to demonstrate, through the analysis of some novels, that the Serna’s city is specified as “the city-subjec”. The author personifies the city and he fuses the soul of novel’s heroes with the local atmosphere. The protagonists are united themselves with the place and ambient, that are influenced by its attitude and the personality. We distinguished two main conceptions of the city in Serna’s works: “a modern city” and “a city-refugium” and their modalities. The modern city is characterized by its ambivalence: it offers an attractive and adventurous modern lifestyle, on the other hand it shows an existential chaos and dehumanization. As opposed to the topos of “the modern city” appears the topos of “the city-refugium” characterized by the historical memory and mythical tradition.

Fresh young (YL and old leaves (OL obtained from three trees in each season (Nov/2010 to Sep/2011 collected in Santa Maria-RS were hydrodistilled in triplicate. The chemical composition was determined by the gas chromatography coupled to mass spectrometry (GC-MS and the yield on dry basis was evaluated by two-way ANOVA (seasons, development stage. Spring (Sp and summer (Su showed higher average incomes (0.45 and 0.33%, which occurred when flowering, fruiting, and growth of YL and senescence of OL took place, while autumn (Au presented the lowest yield (0.25% during the rustification of OL. The highest yield was obtained for the YL in Sp (0.59% and the lowest for the OL in Au (0.21%. The major constituents of the EO were independent from the season and were identified as α-pinene, bicyclogermacrene, β-pinene, germacrene D, and limonene. Seasonality and phenology influenced the production of EO probably due to morphological and metabolic alterations in the leaves as well as due to the needs of the tree, such as attraction and/or protection.

    2016-01-01

    Full Text Available Rapanea melanophloeos is a tropical tree that is extensively utilized in African traditional medicine to treat helminthiases, tuberculosis, and heart-water. As with many other medicinal plants, there is insufficient information regarding the safety of therapeutic R. melanophloeos extracts. An aqueous extract of R. melanophloeos stem bark was administered to Sprague Dawley rats at doses of 100 mg/kg, 300 mg/kg, and 1000 mg/kg for 56 days to characterize its potential toxicity after prolonged dosing. Blood samples were obtained fortnightly for serum chemistry and hematology, while organs were collected at the end of the study. The extract caused an increase in organ weight indices of the kidneys and testis at 300 mg/kg and 1000 mg/kg. Hematological and biochemical examination revealed a drop in leukocyte counts and the hematocrit at 1000 mg/kg dose level, while there was a general but nondose-related elevation in alkaline phosphatase activity. There were time-associated variations in the hematological and clinical chemistry parameters at days 28, 42, and 56 in all dose levels, but most values remained within physiological limits. No pathological lesions were evident at histopathology after treatment with the extract. Our data shows that the aqueous extract of R. melanophloeos is not likely to be toxic at the doses tested and provides support to its medicinal use.

    1997-06-01

    Full Text Available One of the advantages of land cover monitoring by means of satellite images is to have several observations of a specific place. That gives us the possibility of detecting land changes. This paper exemplifies the use of change detection techniques and illustrates how the combination of digital image information and ancillary data in a geographic information system can give us a much clear idea of the ecological importance of transformations. A semiarid zone, in the Tamaulipas and Nuevo León States was selected. This area, south of the US border, is part of the San Juan River basin. The change image was obtained from the vegetation index difference of 3 Landsat MSS images. This change image was combined with digital land use maps to produce the change distribution. This procedure flags a marked decrease in the extent of the water bodies, an increase in vegetation cover in areas of temporal agriculture and grassland, and the little variation of the forested areas. With the aid of the elevation model it was possible to discriminate the change in areas of high water erosion risk. The loss of the vegetation cover in areas of high slope is not frequent.

    Full Text Available A imbuia apresenta sementes recalcitrantes, com forte dormência tegumentar, irregularidade e baixa germinação, dificultando sua propagação natural. O objetivo deste trabalho foi avaliar a germinação in vitro de eixos embrionários de imbuia, testando o efeito de diferentes concentrações de sacarose, de carvão ativado e de formulações salinas para acelerar a produção de mudas. Eixos embrionários zigóticos foram inoculados em meio de cultura MS/2 contendo diferentes concentrações de sacarose (15, 30, 60 ou 90 g L-1, de carvão ativado (0, 1, 2 ou 3 g L-1 e diferentes formulações salinas (MS, WPM, MS/2 ou WPM/2. Os resultados indicaram que a adição de 15 g L-1 de sacarose foi insuficiente para promover a germinação dos eixos embrionários e as demais concentrações promoveram entre 45,5 e 59,4% de germinação. Com relação às formulações salinas, os melhores resultados foram obtidos com os meios de cultura MS e MS/2 obtendo-se 67,7 e 74,2% de germinação, respectivamente. A adição de carvão ativado favoreceu a germinação in vitro dos eixos embrionários, enquanto que na ausência de carvão ativado não ocorreu germinação e houve elevada porcentagem de oxidação. A germinação in vitro de imbuia é viável e pode ser obtida com eixos embrionários zigóticos maduros com a formulação salina MS/2, suplementada com 30 g L-1 de sacarose e 1g L-1 de carvão ativado.Imbuia has recalcitrant seeds with strong tegumental dormancy, irregular and low germination, which impair natural propagation. The objective of this study was to evaluate the in vitro germination of imbuia embryonic axes by testing the effect of different concentrations of sucrose, activated charcoal and salt formulations in order to accelerate the production of plants. Zygotic embryonic axes were inoculated in MS/2 culture medium with different concentrations of sucrose (15, 30, 60 or 90 g L-1, of activated charcoal (0, 1, 2 or 3 gL-1 and in different salt formulations (MS, WPM, MS/2 or WPM/2. The results indicated that the addition of 15 g L-1 sucrose was not enough to promote germination of embryonic axes and the other concentrations promoted between 45.5 and 59.4% germination. The best results were observed with MS and MS/2 salt formulations obtained 67.7 and 74.2% of germination respectively. The addition of activated charcoal to the media favored the in vitro germination of zygotic embryonic axes, while oxidation of the embryo tissues occurred in media without activated charcoal and germination did not happen. The in vitro germination of imbuia can be achieved with the MS/2 salt formulation supplemented with 30 g L-1 sucrose and 1 g L-1 of activated charcoal.

  5. Spatial distribution by Canistropsis microps (E. Morren ex Mez Leme (Bromeliaceae: Bromelioideae in the Atlantic rain forest in Ilha Grande, Southeastern Brazil

    AF. Nunes-Freitas

    Full Text Available Canistropsis microps (Bromeliaceae: Bromelioideae is an endemic species of Atlantic rain forest areas in Rio de Janeiro State, which are very abundant in not very disturbed forests in Ilha Grande, on the southern coast of the State. In this study, we analyzed the vertical and horizontal distribution patterns of the species in an area of rain forest with little evidence of disturbance at Vila Dois Rios, Ilha Grande, relating the patterns to sunlight in the microhabitat. We also identified the types of substrate used by the species and the rate of asexual reproduction. Canistropsis microps had high densities (estimated at 84,425 rosettes/ha, and has an aggregated distribution (Id = 2.86. About 80% of the rosettes were generated by clonal growth, whereas less than 20% were produced from seedlings. Most of the rosettes were found on straight tree trunks (DBH > 50 cm. There was a significant inverse correlation between the incidence of sunlight in the habitat and the abundance of individuals. Rosettes were found up to a maximum height of 9.5 m, but most occured between 1.5 and 5.5 m, where light varied from 25 to 50 µmol.s-1.m-2. We conclude that vertical and horizontal distribution patterns in C. microps may be partially explained by the occurrence of appropriate substrate, an intensity of sunlight favorable to the development of the species and to a high rate of vegetative reproduction.

    Full Text Available El texto nos acerca a una realidad declarada ignorada, que suscita la fantasía y la especulación morbosa de lo desconocido, de aquello que situamos entre la leyenda, lo esotérico y la realidad. Aleccionados en el prejuicio contra la masonería, hemos crecido en los temores, malentendidos, estereotipos e incluso una cierta estigmatización de masones y logias, presentes en el recorrido de nuestra historia, teñida por las luchas políticas y fratricidas de las diversas Españas y el, recordado en el libro, “contubernio judeo masónico”.

    Full Text Available Allelopathic substances can be used to develop weed control alternatives based on natural products. The objective of this study was to compare the phytotoxic activity of aqueous leaf extracts of Rapanea umbellata with the toxicity of a synthetic herbicide on the germination and growth of weed species. The weeds species barnyard grass (Echinochloa crus-galli, wild poinsettia (Euphorbia heterophylla and morning glory (Ipomoea grandifolia were used. The effects of the aqueous leaf extract of R. umbellata at concentrations of 10% and 5% (g mL-1 were compared to the control (distilled water and to the synthetic herbicide oxyfluorfen. The average weed germination time was significantly lower (p < 0.05 in control than in extract and herbicide treatments. The herbicide had more significant effects than the extract on the initial growth of the aerial part. However, the initial growth of the root part was significantly more affected by the leaf extract than by the herbicide. The extract also caused many disorders in weed root anatomy. Therefore, the leaf aqueous extract of R. umbellata showed important results that indicate that it should be bioprospected and that its allelochemicals should be purified for the discovery of natural-origin herbicides.

  9. The typification of Cordia flavescens Aubl., the transfer of Firensia Scop. from Cordia L. (Cordiaceae; Boraginales) to the synonymy of Ocotea Aubl. (Lauraceae), and the identity of the species of Firensia

    Abstract Firensia Scop. was based on Cordia flavescens Aubl., a species described and illustrated from a mixed collection that Scopoli never transferred to Firensia . The genus included three additional species formally named by Rafinesque. Currently the four species are placed in three different families and none retained the epithet accepted by Scopoli or given by Rafinesque for reason of priority. A lectotype is designated for Cordia flavescens that places Firensia in the synonymy of Ocote...

    Full Text Available Na medicina natural pouco se sabe sobre a importância curativa da maior parte das espécies pertencentes à Bromeliaceae. Tal fato evidencia a necessidade da realização de investigações para a comprovação de possíveis potenciais fitoterápicos em espécies dessa família. Guzmania lingulata é caracterizada como sendo uma das espécies de bromélia mais comercializada e conhecida popularmente, a qual é amplamente propagada no Brasil. O presente trabalho objetivou a caracterização anatômica e a identificação de classes de metabólitos secundários presentes em G. lingulata, por meio de análises anatômicas, histoquímicas e químicas. As folhas foram fixadas em FAA 50 e transferidas para etanol 50%. Para o estudo anatômico, secções transversais da porção mediana das lâminas foliares foram obtidas à mão livre e submetidas ao processo de dupla coloração com safranina e azul de astra, sendo, logo após, montadas em gelatina glicerinada. Para a triagem das classes de metabólitos secundários foram coletadas 10 folhas frescas que passaram pelo processo de maceração em solução hidroalcoólica 70% por sete dias, à temperatura ambiente. O filtrado resultante da filtração a vácuo foi evaporado sob vácuo a temperatura de 50ºC até a remoção total do etanol, sendo obtido desta forma o extrato bruto hidroalcoólico a frio (EBHF. Os resultados das secções histológicas permitiram a caracterização anatômico-foliar baseada na qualidade das secções manuais obtidas. Os testes em relação às classes de metabólitos secundários revelaram a presença de antocianinas e taninos e ausência de flavonóides e saponinas. Esses resultados estimulam a realização de estudos mais aprofundados para identificar e quantificar os compostos dessas e de outras classes de metabólitos.

    The source of the Río Tinto (SW Spain) is currently located close to the Peña de Hierro mine, where it receives the first acidic waters. A few kilometers south, the river crosses the Río Tinto mines, a supergiant massive sulfide deposit that is much more important than those of Peña de Hierro, and the acid pollutant contributions to the river increase by orders of magnitude.

    Heraclio Bonilla Mayta

    2012-01-01

    Full Text Available El libro reciente de Katherine Bonil, historiadora de la Universidad de los Andes, es una importante contribución al conocimiento de la formación de las identidades étnicas, en este caso en el contexto de Mariquita en el siglo XVIII. El papel que tuvieron los grupos de poder local en esa definición es sin duda central, como lo reconoce, con razón la autora.; aunque no es menos importante saber que esas identidades no se construyeron solo de manera vertical, sino en la interacción cotidiana de grupos que compartieron una misma posición, aunque separados y opuestos por razones raciales y culturales. Pese a que Mariquita tuvo una población india originaria relativamente pequeña, no hay que olvidar que durante el auge de la actividad minera en el siglo XVII fue el centro de movilización compulsiva, la así llamada “mita” neogranadina, de cientos de nativos procedentes de Santafé de Bogotá y de Tunja para extraer el metal de sus socavones.

  18. Pollen morphology of the family crassulaceae from pakistan and kashmir and its taxonomic implications

    Qasir, M.; Perveen, A.; Sarwar, G.R.

    2015-01-01

    Pollen morphology of 28 species representing 9 genera viz., Bryophyllum, Kalanchoe, Pseudosedum, Rhodiola, Rosularia, Hylotelephium, Sedum, Tillaea and Orostachys of the family Crassulaceae from Pakistan has been studied by light and scanning electron microscope. Pollen grains are usually free, radially symmetrical, isopolar, sub-oblate to oblate-spheroidal, or prolate-spheroidal to subprolate often prolate and tricolporate. Tectum mostly striate-rugulate or sub-psilate rarely reticulate-rugulate. Significant variation is found in shape and exine ornamentation and on the basis these characters family has been divided into three pollen types' viz., Rhodiola sinuata-type, Rosularia viguieri-type and Sedum hispanicum-type. Numerical analysis of based on pollen characters of 28 species was also carried out to determine the phylogenetic relationships of various genera and the species of the family Crassulaceae. (author)

    Full Text Available The Lauraceae, a characteristic family of Peru’s eastern montane forests are represented in Peru by 16 genera and 247 species (Brako & Zarucchi, 1993; Ulloa Ulloa et al., 2004. Here we recognize 55 endemic species included in 11 genera. Nectandra and Ocotea are the genera with the largest number of endemic species. These endemic taxa, mostly trees and shrubs, are found mainly in the Humid Lowland Amazonian Forest and Very Humid Montane Forest regions, between 125 and 3100 m elevation. Nine of these species have been recorded to date in the Peruvian protected areas system.

  1. Identification of Four Wood Species by an Electronic Nose and by LIBS

    Full Text Available This paper presents two complementary methods capable of identifying four wood species (Cedrela fissilis, Ocotea porosa, Hymenolobium petraeum, and Aspidosperma subincanum both by their volatile organic compounds and by the presence of 10 chemical elements: Al, B, Ca, Mg, Zn, Cu, Mn, Fe, Na, and Si. The volatile compounds were detected by an electronic nose formed by an array of three different conductive polymer gas sensors. The elemental determination was made by laser-induced breakdown spectrometry (LIBS. The emissions measured were treated by principal component analysis (PCA. Leave-one-out analysis showed a rate of hits of 100%.

    In a rapidly changing world understanding of natural ecosystems response to human perturbations such as land use and climate changes as well as habitat destruction is crucial with respect to sustainability of ecosystem services. This is particularily true for tropical forest ecosystems which have significant effects on the major biogeochemical cycles and global climate. Here we present a comprehensive dataset of nitrogen cycling and GHG emissions of natural and managed ecosystems along land use and climate gradients at Mt. Kilimanjaro, Tanzania including different forest ecosystems, homegardens, and coffee plantations. Soil N turnover rates were highest in the Ocotea forest and progressively decreased with decreasing annual rainfall and increasing land use intensity. Nitrogen production and immobilization rates positively correlated with soil organic C and total N concentrations as well as substrate availability of dissolved organic C and N, but correlated less with soil ammonium and nitrate concentrations. By using indicators of N retention and characteristics of soil nutrient status, we observed a grouping of faster, but tighter N cycling in the (semi-) natural savanna, Helychrysum and Ocotea forest. This contrasted with a more open N cycle in managed systems (homegarden and coffee plantation) where N was more prone to leaching or gaseous losses due to high nitrate production rates. The partly disturbed lower montane forest ranged in between these two groups. These finding could be supported by differences in natural 15N abundance of litter and soil across all sites. Comparing GHG emissions at the land use gradient showed, that with increasing intensification (lower montane forest - homegarden - coffee plantation) N2O emissions increased but at the same time the soil sink for atmospheric CH4 decreased. GHG emission measurements at the climate gradient (savanna, lower montane, Ocotea and Podocarpus forest, Helychrysum) revealed that differences in soil moisture

    Full Text Available Os tipos de placentação e de pré-floração têm sido utilizados para a distinção dos gêneros Ardisia Swartz, ao qual tem sido atribuído placentação plurisseriada e pré-floração imbricada ou quincuncial, e Stylogyne A.DC., ao qual tem sido atribuído placentação unisseriada e pré-floração contorta. Entretanto, a análise de dez espécies destes gêneros revelou a inconsistência destes caracteres. Também foi constatada a impossibilidade de observar diferenças no tipo de placentação em espécimes com poucos óvulos. Propõe-se, portanto, o restabelecimento da circunscrição de Ardisia, incluindo o gênero Stylogyne, conforme adotado por Miquel, em 1856 e Handro, em 1969. Desta forma, Ardisia ambigua Mart. é o nome válido para S. ambigua (Mart. Mez e Ardisia martiana Miq. o é para S. laevigata (Mart. Mez. Duas novas combinações são necessárias: Ardisia depauperata (Mez Bernacci & Jung-Mendaçolli e Ardisia warmingii (Mez Bernacci & Jung-Mendaçolli.Placentation and aestivation have traditionally been used as diagnostic features to separate the genera Ardisia Swartz and Stylogyne A.DC. While Ardisia has pluriseriate placentation and imbricate or quincuncial aestivation, Stylogyne has uniseriate placentation and contorted aestivation. However, careful examination of ten species of these genera revealed the inconsistency of these characters in the distinction of the two genera. Also, we noticed the impossibility of observation of placentation types in few-ovuled specimens. Therefore, we propose the re-establishment of the circumscription of Ardisia adopted by Miquel, in 1856, and Handro, in 1969 which includes the genus Stylogyne. In this way Ardisia ambigua Mart. is the valid name for S. ambigua (Mart. Mez as Ardisia martiana Miq. is for S. laevigata (Mart. Mez. Two new combinations are necessary: Ardisia depauperata (Mez Bernacci & Jung-Mendaçolli and Ardisia warmingii (Mez Bernacci & Jung-Mendaçolli.

    2014-09-01

    Full Text Available Wood wastes are potential material for second generation ethanol production within the concept of residual forest bio-refinery. Current paper reports on ethanol production employing an HPLC method for monitoring the chemical content dispersed in the hydrolysate liquor after fermented. The proton-exchange technique was the analytical method employed. Twelve types of wood chips were used as biomass, including Hymenolobium petraeum, Tabebuia cassinoides, Myroxylon peruiferum, Nectandra lanceolata, Ocotea catharinensis, Cedrelinga catenaeformis, Cedrela fissilis Vell, Ocotea porosa, Laurus nobilis, Balfourodendron riedelianum, Pinus Elliotti and Brosimum spp. The influence of diluted sulfuric hydrolysis on the yeast Saccharomyces cerevisiae during the fermentation assay was also investigated. Standard compounds mapped in the analysis comprised fructose, lactic acid, acetic acid, glycerol, glucose and ethanol. The yeast showed ethanol productivity between 0.75 and 1.91 g L-1 h-1, respectively, without the addition of supplementary nutrients or detoxification. The use of these materials for the bioconversion of cellulose into ethanol has been proved. Current analysis contributes towards the production of biofuels by wastes recovery and by process monitoring and optimization.

    Full Text Available Chagas disease is one of the main public health problems in Latin America. Since the available treatments for this disease are not effective in providing cure, the screening of potential antiprotozoal agents is essential, mainly of those obtained from natural sources. This study aimed to provide an evaluation of the trypanocidal activity of 92 ethanol extracts from species belonging to the families Annonaceae, Apiaceae, Cucurbitaceae, Lamiaceae, Lauraceae, Moraceae, Nyctaginaceae, and Verbenaceae against the Y and Bolivia strains of Trypanosoma cruzi. Additionally, cytotoxic activity on LLCMK2 fibroblasts was evaluated. Both the trypanocidal activity and cytotoxicity were evaluated using the MTT method, in the following concentrations: 500, 350, 250, and 100 µg/mL. Benznidazole was used for positive control. The best results among the 92 samples evaluated were obtained with ethanol extracts of Ocotea paranapiacabensis (Am93 and Aegiphila lhotzkiana (Am160. Am93 showed trypanocidal activity against epimastigote forms of the Bolivia strain and was moderately toxic to LLCMK2 cells, its Selectivity Index (SI being 14.56, while Am160 showed moderate trypanocidal activity against the Bolivia strain and moderate toxicicity, its SI being equal to 1.15. The screening of Brazilian plants has indicated the potential effect of ethanol extracts obtained from Ocotea paranapiacabensis and Aegiphila lhotzkiana against Chagas disease.

    2015-06-01

    Full Text Available Floristic composition and structure of the tree component were analyzed in a coastal peat forest of the Toto Beach, located in the southern region of Lagoa dos Patos (31º43’39”S e 52º12’04”W. The phytosociological sampling was conducted on a sample area of 0.1 ha. All trees with DBH ≥ 4.8 cm were included. The species richness found was equivalent to 23 species distributed in 20 genera and 15 families. Two endangered species were sampled. The total tree density estimated for one hectare was equivalent to 3,480 trees. The most important species in the forest structure were Ocotea sp., Myrcia multiflora, Psidium cattleyanum, Ocotea pulchella, Myrsine lorentziana, Citharexyllum myrianthum, Ilex dumosa, Syagrus romanzoffiana, Guapira opposita and Sebastiania brasiliensis. The species diversity estimated by the Shannon index was 2,174 nats.ind.-1 and evenness (J was 0.684. The forest structure, number of taxa and diversity are similar to other surveys carried out in swamp forests of southern and southeastern Brazil. These parameters must be considered in the environmental licensing and ecological restoration projects of this forest type.

    2002-01-01

    Full Text Available This study investigated the regeneration variation of five commercially valuable tree species in relation to different intensities of felling in fourteen 4-ha plots in an area under experimental forest management. This experiment was carried out in a typical Amazonian tropical forest sample on "terra-firme," in Manaus (AM. Plots were logged 7 and 8 years (1987 and 1988, or 3 years (1993 before the study. All trees with height greater than 2 m, and diameter at breast height (DBH smaller than 10 cm were measured. Only Aniba hostmanniana, Ocotea aciphylla, Licaria pachycarpa, Eschweilera coriacea and Goupia glabra were sufficiently common for individual analyses. These species have high timber values in the local market. Eight years after logging, the species responded differently to logging intensities. The numbers of individuals of Goupia glabra and Aniba hostmanniana were positively related to the intensity of logging, while Ocotea aciphylla, Licaria pachycarpa, and Eschweilera coriacea showed no statistically significant response. In the most recently (1993 logged areas, Goupia glabra and Aniba hostmanniana had higher numbers of individuals than the control plots.

    Full Text Available The central focus of this study was to determine the overall perceptions of school administrators, and the district bilingual coordinator on transferring theory to classroom practice, implementation, as viewed by those involved in the implementation process of the Gómez and Gómez Model of Dual Language Education. Responses were solicited from administrative personnel involved in the implementation of the Gómez and Gómez Model of Dual Language. Results revealed overall administrative attitudes were positive to the theoretical ideology and mixed as related to the actual implementation of the dual language program. The greatest areas of concern were; what to do when students enter the program who are either not Spanish dominant or who have not been in a dual language program. The second area of concern was with how to effectively evaluate teachers as they are observed for implementation of the dual langue program. Lastly, most administrators felt there was a lack of faculty proficient in Spanish.

We define a new species group: the amazonica species-group, to accommodate the following five species: X. amazonica Gómez, Sääksjärvi & Veijalainen, X. guianensis Gómez & Sääksjärvi sp. n., X. jussilai Veijalainen, Sääksjärvi & Broad, X. pucallpensis Gómez & Sääksjärvi sp. n. and X. vidali Gómez sp. n. The aurita species-group, which had hitherto been regarded as the only species-group in the Neotropical region, is currently represented by five species: X. allpahuaya Gómez & Sääksjärvi sp. n., X. aurita Krieger, X. craspedoptera Krieger, X. rhabdomera Townes and X. spiloptera Krieger. The Andean species X. peruana Krieger is established as an unplaced species outside of the amazonica and aurita species-groups. A key to Neotropical species-groups and species of Xanthopimpla is provided. Xanthopimpla aurita is recorded for the first time from Ecuador and Colombia and its extensive distribution is discussed. Xanthopimpla amazonica, X. craspedoptera and X. jussilai are recorded for the first time from Brazil; X. amazonica is recorded for the first time from French Guiana; X. spiloptera is recorded for the first time from French Guiana and Peru, and X. rhabdomera is recorded for the first time from Peru.

    Full Text Available The Sergipe-Alagoas Basin has one of the most complete, exposed lithological successions of the Cretaceous period in the continental margin of Brazil. It captures several phases of the evolution of the South Atlantic Ocean, including rift, gulf and drift. The upper Aptian–Albian Riachuelo Formation corresponds to the first stages of the southern proto-Atlantic Ocean invasion in that basin. The present study reviews the taxonomic identification and ecology of 39 ostracod species of this formation, proposing a new genus – Gabonorygma gen. nov. – and three new species – Praebythoceratina deltalata sp. nov., Gabonorygma sergipana gen. et sp. nov. and Brachycythere smithsoniana sp. nov.

  2. Interspecific Plant Interactions Reflected in Soil Bacterial Community Structure and Nitrogen Cycling in Primary Succession

    Joseph E. Knelman

    2018-02-01

    Full Text Available Past research demonstrating the importance plant–microbe interactions as drivers of ecosystem succession has focused on how plants condition soil microbial communities, impacting subsequent plant performance and plant community assembly. These studies, however, largely treat microbial communities as a black box. In this study, we sought to examine how emblematic shifts from early successional Alnus viridus ssp. sinuata (Sitka alder to late successional Picea sitchensis (Sitka spruce in primary succession may be reflected in specific belowground changes in bacterial community structure and nitrogen cycling related to the interaction of these two plants. We examined early successional alder-conditioned soils in a glacial forefield to delineate how alders alter the soil microbial community with increasing dominance. Further, we assessed the impact of late-successional spruce plants on these early successional alder-conditioned microbiomes and related nitrogen cycling through a leachate addition microcosm experiment. We show how increasingly abundant alder select for particular bacterial taxa. Additionally, we found that spruce leachate significantly alters the composition of these microbial communities in large part by driving declines in taxa that are enriched by alder, including bacterial symbionts. We found these effects to be spruce specific, beyond a general leachate effect. Our work also demonstrates a unique influence of spruce on ammonium availability. Such insights bolster theory relating the importance of plant–microbe interactions with late-successional plants and interspecific plant interactions more generally.

  4. Diet composition of nestlings and adults of the threatened Bolivian Swallow-tailed Cotinga Phibalura flavirostris boliviana (Aves: Passeriformes: Cotingidae in Bolivia

    Verónica del Rosario Avalos

    2015-08-01

    Full Text Available The qualitative and quantitative composition of the nestling and adult diet of the threatened Swallow-tailed Cotinga Phibalura flavirostris boliviana was studied through the analysis of fecal samples.  Nestling diet consisted of 62% fruit and 38% insects but varied according to the nestling age. The diet of adults was made up of 89% fruit and 11% insects.  The fruit eaten came primarily from the trees Schefflera morototoni, Hyeronima moritziana and Ocotea cuprea.  Most insects in the fecal samples were winged-species of the orders Hymenoptera and Coleoptera.  This species relied mostly on fruiting trees from semi-humid forest fragments and isolated trees on mountain savannas.  Thus, management plans for this bird should consider the conservation of these habitats. 

  5. Digging up food: excavation stone tool use by wild capuchin monkeys.

    Falótico, Tiago; Siqueira, José O; Ottoni, Eduardo B

    2017-07-24

    Capuchin monkeys at Serra da Capivara National Park (SCNP) usually forage on the ground for roots and fossorial arthropods, digging primarily with their hands but also using stone tools to loosen the soil and aid the digging process. Here we describe the stone tools used for digging by two groups of capuchins on SCNP. Both groups used tools while digging three main food resources: Thiloa glaucocarpa tubers, Ocotea sp roots, and trapdoor spiders. One explanation for the occurrence of tool use in primates is the "necessity hypothesis", which states that the main function of tool use is to obtain fallback food. We tested for this, but only found a positive correlation between plant food availability and the frequency of stone tools' use. Thus, our data do not support the fallback food hypothesis for the use of tools to access burrowed resources.

    2013-12-01

    Full Text Available The research was conducted in the Jeringa site of the Turquino National Park in order to characterize the vegetation of a mountain forest fragment with Juglans jamaicensis. Floristic composition, vegetation structure, and the index value of importance were evaluated. Diameter at 1.30 m above the ground and height of all trees greater than 5 cm in diameter was measured. Data were analyzed using canonical correspondence analysis. 776 individuals of 43 species and 41 genera belonging to 30 families, reporting the Rubiaceae family as the richest in species, followed by Amigdalaceae, Araliaceae, Cyatheaceae, Euphorbiaceae, Flacourtiaceae, Meliaceae, Moraceae, Sapindaceae and Poaceae. The tree species with more IVI were the Pseudolmedia spuria, Oxandra laurifolia, Trophis racemosa, Ocotea leucoxylon, Guarea guara, Dendropanax arboreus and Juglans jamaicensis, mainly due to its abundance in the vegetation, but it was found that the main contributor to the organic weight parameter species was the relative frequency.

  7. Seed predation by mammals in forest fragments in Monteverde, Costa Rica

    Federico A Chinchilla

    2009-09-01

    Full Text Available Few studies have evaluated seed predation in fragmented landscapes, in which lower species diversity is expected to modifying ecological interactions. The rates of seed removal by mammals were investigated in a continuous forest and two fragmented patches of Premontane Tropical Moist Forest, in Monteverde, Costa Rica. The composition of mammalian seed-predators in each site was recorded during 16 months. The removal of four native tree species of experimental seeds: Ocotea valeriana and Ocotea whitei (Lauraceae, Panopsis costaricensis (Proteaceae and Billia colombiana (Hippocastanaceae in forest understories was followed during two annual fruiting seasons for each species. Results indicated similar species composition of seed-predators between continuous forest, the largest fragment (350 ha. However the smaller fragment (20 ha, had fewer seed predators. In this fragment, the specialized seed predator Heteromys desmarestianus (Rodentia was more abundant. Unexpectedly, seed-predation in the two forest fragments and the continuous forest did not differ statistically for any of the seed species. Apparently, the higher abundance of small seed-predators in the fragments was compensated by the absence of medium and large seed-predators, like Agouti paca, Dasyprocta punctata (both Rodentia and Pecari tajacu (Artiodactyla recorded in continuous forest. Removal of experimentally-placed seeds was higher when the number of naturally occurring seeds in the sites was lower. This result could best be attributed to differential satiation of seed predators rather than differences in richness or abundance of seed predators. Rev. Biol. Trop. 57 (3: 865-877. Epub 2009 September 30.Pocos estudios han evaluado la depredación de semillas en ambientes fragmentados, en éstos la menor diversidad de especies debe estar modificando las interacciones ecológicas.

  16. Soil microbial metabolic quotient (qCO2) of twelve ecosystems of Mt. Kilimanjaro

    Pabst, Holger; Gerschlauer, Friederike; Kiese, Ralf; Kuzyakov, Yakov

    2014-05-01

    Soil organic carbon, microbial biomass carbon (MBC) and the metabolic quotient qCO2 - as sensitive and important parameters for soil fertility and C turnover - are strongly affected by land-use changes all over the world. These effects are particularly distinct upon conversion of natural to agricultural ecosystems due to very fast carbon (C) and nutrient cycles and high vulnerability, especially in the tropics. In this study, we used an elevational gradient on Mt. Kilimanjaro to investigate the effects of land-use change and elevation on Corg, MBC and qCO2. Down to a soil depth of 18 cm we compared 4 natural (Helichrysum, Erica forest, Podocarpus forest, Ocotea forest), 5 seminatural (disturbed Podocarpus forest, disturbed Ocotea forest, lower montane forest, grassland, savannah), 1 sustainably used (homegarden) and 2 intensively used ecosystems (coffee plantation, maize field) on an elevation gradient from 950 to 3880 m a.s.l.. Using an incubation device, soil CO2-efflux of 18 cm deep soil cores was measured under field moist conditions and mean annual temperature. MBC to Corg ratios varied between 0.7 and 2.3%. qCO2 increased with magnitude of the disturbance, albeit this effect decreased with elevation. Following the annual precipitation of the ecosystems, both, Corg and MBC showed a hum-shaped distribution with elevation, whereas their maxima were between 2500 and 3000 m a.s.l.. Additionaly, Corg and MBC contents were significantly reduced in intensively used agricultural systems. We conclude that the soil microbial biomass and its activity in Mt. Kilimanjaro ecosystems are strongly altered by land-use. This effect is more distinct in lower than in higher elevated ecosystems and strongly dependent on the magnitude of disturbance.

  18. Phyllosphere Metaproteomes of Trees from the Brazilian Atlantic Forest Show High Levels of Functional Redundancy.

    Lambais, M R; Barrera, S E; Santos, E C; Crowley, D E; Jumpponen, A

    2017-01-01

    The phyllosphere of the Brazilian Atlantic Forest has been estimated to contain several million bacterial species that are associated with approximately 20000 plant species. Despite the high bacterial diversity in the phyllosphere, the function of these microorganisms and the mechanisms driving their community assembly are largely unknown. In this study, we characterized the bacterial communities in the phyllospheres of four tree species of the Atlantic Forest (Mollinedia schottiana, Ocotea dispersa, Ocotea teleiandra, and Tabebuia serratifolia) and their metaproteomes to examine the basic protein functional groups expressed in the phyllosphere. Bacterial community analyses using 16S rRNA gene sequencing confirmed prior observations that plant species harbor distinct bacterial communities and that plants of the same taxon have more similar communities than more distantly related taxa. Using LC-ESI-Q-TOF, we identified 216 nonredundant proteins, based on 3503 peptide mass spectra. Most protein families were shared among the phyllosphere communities, suggesting functional redundancy despite differences in the species compositions of the bacterial communities. Proteins involved in glycolysis and anaerobic carbohydrate metabolism, solute transport, protein metabolism, cell motility, stress and antioxidant responses, nitrogen metabolism, and iron homeostasis were among the most frequently detected. In contrast to prior studies on crop plants and Arabidopsis, a low abundance of OTUs related to Methylobacterium and no proteins associated with the metabolism of one-carbon molecules were detected in the phyllospheres of the tree species studied here. Our data suggest that even though the phyllosphere bacterial communities of different tree species are phylogenetically diverse, their metaproteomes are functionally convergent with respect to traits required for survival on leaf surfaces.

    Summary The trunk wood of Aniba kappleri Mez (family Lauraceae) contains besides sitosterol, octacosanoic acid and rhamnocitrin (7-O-methylkaempferol), three esters, namely benzyl benzoate, benzyl 2-hydroxybenzoate and benzyl 2,6-dihydroxybenzoate, and two α-pyrones, namely 4-methoxy-6- (E) -(3',4'-methy!enedioxystyryl)-2-pyrone and 4-methoxy-6-{E)-(3',4'-dimethoxystyryl]-2pyrone. A dimer of the latter compound, which was obtained additionally, is considered to be an artifact.

  2. Effective degree Markov-chain approach for discrete-time epidemic processes on uncorrelated networks.

    Cai, Chao-Ran; Wu, Zhi-Xi; Guan, Jian-Yue

    2014-11-01

    Recently, Gómez et al. proposed a microscopic Markov-chain approach (MMCA) [S. Gómez, J. Gómez-Gardeñes, Y. Moreno, and A. Arenas, Phys. Rev. E 84, 036105 (2011)PLEEE81539-375510.1103/PhysRevE.84.036105] to the discrete-time susceptible-infected-susceptible (SIS) epidemic process and found that the epidemic prevalence obtained by this approach agrees well with that by simulations. However, we found that the approach cannot be straightforwardly extended to a susceptible-infected-recovered (SIR) epidemic process (due to its irreversible property), and the epidemic prevalences obtained by MMCA and Monte Carlo simulations do not match well when the infection probability is just slightly above the epidemic threshold. In this contribution we extend the effective degree Markov-chain approach, proposed for analyzing continuous-time epidemic processes [J. Lindquist, J. Ma, P. Driessche, and F. Willeboordse, J. Math. Biol. 62, 143 (2011)JMBLAJ0303-681210.1007/s00285-010-0331-2], to address discrete-time binary-state (SIS) or three-state (SIR) epidemic processes on uncorrelated complex networks. It is shown that the final epidemic size as well as the time series of infected individuals obtained from this approach agree very well with those by Monte Carlo simulations. Our results are robust to the change of different parameters, including the total population size, the infection probability, the recovery probability, the average degree, and the degree distribution of the underlying networks.

  5. Repeated exposure to enhanced UV-B radiation in successive generations increases developmental instability (leaf fluctuating asymmetry) in a desert annual

    Midgley, G.F.; Wand, S.J.E.; Musil, C.F.

    1998-01-01

    Populations of the desert annual Dimorphotheca sinuata, derived from a common seed stock, were exposed concurrently over four successive generations to either ambient (representing no stratospheric ozone depletion) or elevated (representing 20% stratospheric ozone depletion) UV-B levels during their complete life cycle. Leaf fluctuating asymmetry (FA) was measured in populations of plants grown from seeds of selected generations which had experienced different UV-B exposure histories, and from seeds collected from a wild population of this species which grows in a naturally enhanced UV-B environment. These measured plants had been grown in a greenhouse under essentially UV-B-free conditions. Leaf FA was significantly increased by greater numbers of enhanced UV-B exposures in the parentage of the seed. There was a linear to exponential dose–response relationship between number of UV-B exposure iterations in seed parentage and leaf FA, suggesting that damage to DNA caused by UV-B exposure during plant development may not be fully repaired, and thus be inherited by offspring and accumulated over successive generations in this species. Leaf FA of plants grown from seed from the wild population was not significantly greater than that of control plants whose parentage experienced only ambient UV-B exposures, although this negative result may have been due to low sampling intensity and measurement resolution, and the relatively low UV-B enhancement experienced by the wild population. We conclude that leaf FA may constitute a relatively sensitive yet inexpensive means of quantifying UV-B damage to plants. (author)

  6. Effects of copper on species composition of periphyton in a Sierra Nevada, California, stream

    Leland, H.V.; Carter, J.L.

    1984-06-01

    Changes in species composition of the periphyton of an oliotrophic, Sierra Nevada stream continuously dosed for 1 year at three concentrations of copper (2.5, 5 and 10..mu..g 1/sup -1/ Cu/sub T/; approximately 12, 25 and 50 ng 1/sup -1/ Cu/sup 2 +/) were determined. The numerically most abundant taxa were Bacillariophyceae (Achnanthes minutissima, Cocconeis placentula, Cymbella microcephala, C. sinuata, Fragilaria construens, F. crotonensis, Navicula spp., Synedra acus and S. rumpens), and the Cyanophyta Lynbya spp., a co-dominant during spring and summer. Population densities of Lyngbya spp. were markedly reduced at all test concentrations of copper. Population densities of the principal Chlorophyta (Spirogyra spp. and Cladophora spp.) and the diatom Amphipleura pellucida were reduced at 5 ..mu..g 1/sup -1/ Cu/sub T/. Of the twenty-two most abundant taxa, sixteen were reduced in abundance by continuous exposure to 10 ..mu..g 1/sup -1/ Cu/sub T/. There was no commensurate reduction in standing crop (total number of individuals of all taxa). Achnanthes minutissima, a co-dominant in the control, was the primary replacement species. Other taxa that were more abundant at 5 ..mu..g 1/sup -1/ Cu/sub T/ than in the control were Ceratoneis arcus, Cocconeis placentula, Navicula spp. and Synedra rumpens. Only A. minutissima and Calothrix spp. were more abundant at l10 ..mu..g 1/sup -1/ than in the control. Three resemblance measures (Canberra metric, Bray-Curtis and Dice) and diversity (Brillouin's) were evaluated for detecting differences in species composition among experimental stream sections. The Canberra metric, an index sensitive to proportional rather than absolute differences, was the most informative of these indices.

  7. DISEÑO DE UN SISTEMA DE BIOFILTRACIÓN PARA LA REMOCIÓN DE ESTIRENO

    Esteban Jiménez

    Full Text Available El presente trabajo se enfocó en desarrollar un proceso para la eliminación del gas estireno, un contaminante orgánico generador de malos olores en el aire. Se construyó un sistema de biofiltración en el cual se emplearon bacterias del tipo Pseudomona aeruginosa y Escherichia coli adheridas a un soporte de piedra pómez. Se contaminó aire con estireno en concentraciones por encima del estándar norteamericano (TLV 40 ppm, ACGIH 2002, para simular una atmósfera laboral de alto riesgo a la salud. A fin de evaluar la eficiencia del sistema, se midieron directamente las concentraciones de estireno a la entrada y a la salida, utilizando un medidor de vapores orgánicos. Durante los primeros días se obtuvieron remociones por encima del 55%, para un promedio de 5 mediciones diarias, durante un periodo de 10 días. El sistema se fue estabilizando progresivamente durante la fase inicial, por lo que la remoción no fue la óptima. A partir del día 8 se alcanzaron remociones promedio por encima del 70% y remociones específicas superiores al 90%. El soporte de piedra pómez demostró ser una buena alternativa, facilitando la formación de una biopelícula; la rápida saturación de sus microporos permitió garantizar la baja adsorción del compuesto orgánico en el medio (piedra pómez + microorganismos, confirmando un auténtico proceso de biodegradación.

    Full Text Available The floristic and structure alterations were studied in an Ombrophyllous Mixed Forest located in São João do Triunfo (Paraná State - Brazil. Nine plots of 1ha, first evaluated in 1979, were recovered and, measured in 2000. In 1979, all the trees with dbh ≥ 20 cm were identified and tagged, and they had their commercial height and diameter measured. In 2000, based on the same criteria described before, the trees which had not been counted in 1979 were considered as ingrowth, and the missing ones were considered mortality. In 1979, 2133 individuals, 51 species and 29 families were found and in the 2000 survey, 2202 individuals, 55 species and 31 families ware journal. In both surveys, the families Araucariaceae, Aquifoliaceae, Lauraceae, Sapindaceae, Myrtaceae and Canellaceae were the most represented in terms of quantity of individuals. Although in both times more than 50 species were counted, in 1979 only 7 species (Araucaria angustifolia, Ilex dumosa, Matayba elaeagnoides, Ocotea porous, Capsicodendron dinisii, Nectandra grandiflora and Campomanesia xanthocarpa represented 80.4% of the individuals and, in 2000, the same 7 species plus Ocotea corymbosa covered 80.9% of the total number of individuals. Hovenia dulcis, exotic specie, based on the number of adult and regeneration individuals, became to be seen as a threat to the autocnons species. All the structural indicators which were analyzed showed that the community has become more mature during the studied period and that the Araucaria angustifolia increased its dominance. There was a sensible increase of the occupancy grade, indicated by the absolutely dominance that changes from 23.52 m2/ha in 1979, to 28.53 m2/ha, in 2000, an increase of 21.3%. These results indicate that this community is still in development, and has not yet found its equilibrium. It also demonstrates that the Araucaria dominance increased in this period, suggesting that this profile can even increase future in the

    The control and treatment of Leishmaniasis, a neglected and infectious disease affecting approximately 12 million people worldwide, are challenging. Leishmania parasites multiply intracellularly within macrophages located in deep skin and in visceral tissues, and the currently employed treatments for this disease are subject to significant drawbacks, such as resistance and toxicity. Thus, the search for new Leishmaniasis treatments is compulsory, and Ocotea duckei Vattimo, a plant-derived product from the biodiverse Brazilian flora, may be a promising new treatment for this disease. In this regard, the aim of this work was to develop and characterize a delivery system based on solid lipid nanoparticles (SLN) that contain the liposoluble lignan fraction (LF) of Ocotea duckei Vattimo, which targets the Leishmania phagolysosome of infected macrophages. LF-loaded SLNs were obtained via the hot microemulsion method, and their physical and chemical properties were comprehensively assessed using PCS, AFM, SEM, FT-IR, DSC, HPLC, kinetic drug release studies, and biological assays. The size of the developed delivery system was 218.85±14.2 nm, its zeta potential was -30 mV and its entrapment efficiency (EE%) was high (the EEs% of YAN [yangambin] and EPI-YAN [epi-yangambin] markers were 94.21±0.40% and 94.20±0.00%, respectively). Microscopy, FT-IR and DSC assays confirmed that the delivery system was nanosized and indicated a core-shell encapsulation model, which corroborated the measured kinetics of drug release. The total in vitro release rates of YAN and EPI-YAN in buffer (with sink conditions attained) were 29.6±8.3% and 34.3±8.9%, respectively, via diffusion through the cellulose acetate membrane of the SLN over a period of 4 h. After 24 h, the release rates of both markers reached approximately 45%, suggesting a sustained pattern of release. Mathematical modeling indicated that both markers, YAN and EPI-YAN, followed matrix diffusion-based release kinetics (Higuchi

    Air pollution can be defined as: "the introduction into the atmosphere by man, directly or indirectly, of substances or energy with have effects deleterious of such a nature that endangers human health, causing damage to biological resources and to ecosystems, which impair material goods and to harm or interfere with amenities and other legitimate uses of the environment". One of the main pollutants in air is the particulate matter. This material particulate includes settleable, particles larger than 10 μm that remain airborne for relatively short periods of time. For what its effects are most pronounced in the vicinity of the emitting sources. The study area is located in the city of Alcora. This population is located in the region eastern of the province of Castellon (Spain). The municipality of Alcora has a high industrial density, highlighting framed companies in chemical industry and non-metallic mineral products. The area has a high traffic density due to the proximity of population to various roads. These two factors point peaks rise high concentration of atmospheric particulate pollutants. The purpose of this paper is conducting a retrospective view of the evolution of settleable particulate concentrations. Settleable particulate samples were collected with a sensor BRITISH STANDARD PS particles during the period between January 2000 and December 2005.

    fluido obtenido involuntariamente por su paciente: su orina. Un pequeño frasco de vidrio bastaba
    para preparar la prueba. El valor diagnóstico de la orina fue sustentándose con la experiencia médica

    2013-12-01

    Full Text Available What are relativistic jets like within a million Schwarzschild radii of the accreting black hole that powers them? A meeting in Granada, Spain in June 2013, organized by José L. Gómez and his conspirators brought together observers and theorists to survey the current state of observational data and efforts to interpret them. This conference summary reviews the results, insights, arguments, conflicts, and agreements that occurred during five sunny days spent in a windowless room in a hotel at the bottom of the hill that holds the heart of the beautiful city.

    Full Text Available Our study links science, ethics and literature on the subject of animal abuse after the peak surgical period of the 16th and 17th centuries, with advocates of vivisection (Physicians like Gómez Pereira or Descartes and detractors who denounced these practices (Montaigne, Gassendi, Cureau de la Chambre, using the rationality of animals as an argument to respect them. In 18th-century Spain, the response of B. J. Feijoo to this controversy will be compassion, an approach that will mark the way for philosophers, scientists and writers who, after him, will support his proposal to unite scientific progress, ethical consideration and respect for animals.

  1. Anti-quorum sensing activity of essential oils from Colombian plants.

    Jaramillo-Colorado, Beatriz; Olivero-Verbel, Jesus; Stashenko, Elena E; Wagner-Döbler, Irene; Kunze, Brigitte

    2012-01-01

    Essential oils from Colombian plants were characterised by GC-MS, and assayed for anti-quorum sensing activity in bacteria sensor strains. Two major chemotypes were found for Lippia alba, the limonene-carvone and the citral (geranial-neral). For other species, the main components included α-pinene (Ocotea sp.), β-pinene (Swinglea glutinosa), cineol (Elettaria cardamomun), α-zingiberene (Zingiber officinale) and pulegone (Minthostachys mollis). Several essential oils presented promising inhibitory properties for the short chain AHL quorum sensing (QS) system, in Escherichia coli containing the biosensor plasmid pJBA132, in particular Lippia alba. Moderate activity as anti-QS using the same plasmid, were also found for selected constituents of essential oils studied here, such as citral, carvone and α-pinene, although solely at the highest tested concentration (250 µg mL(-1)). Only citral presented some activity for the long chain AHL QS system, in Pseudomonas putida containing the plasmid pRK-C12. In short, essential oils from Colombian flora have promising properties as QS modulators.

  3. Efficacy of extracts from plants of the Brazilian Pantanal against Rhipicephalus (Boophilusmicroplus

    Larissa Bezerra dos Santos

    Full Text Available This research evaluated the in vitro acaricidal activity of extracts from 21 plant species from the Pantanal of Mato Grosso do Sul. During stage I, a larval immersion test was performed using three extract concentrations (5%, 20%, and 40%. During stage II, we used only plants that showed over 95% efficiency at the 40% concentration in stage I in an amount sufficient for the adult immersion test. Aeschynomene denticulata, Angelonia hirta, Aspilia latissima, Caperonia castaneifolia, Centratherum punctatum, Crotalaria micans, Diodia kuntzei, Echinodorus paniculatus, Hyptis mutabilis, Lantana canescens, Melanthera latifolia, Ocotea diospyrifolia, Richardia grandiflora, Sebastiana hispida, Tocoyena formosa, Zanthoxylum rigidum, and Sesbania virgata (fruit extract showed acaricidal activity against the larval stage ofRhipicephalus (Boophilusmicroplus higher than 95% at a 40% (w/v concentration, while Hippocratea volubilis and Randia armatashowed moderate efficacy and Croton glandulosus andSenna obtusifolia had no effect. The M. latifolia, A. hirta, R. grandiflora, and A. latissima raw extracts were evaluated for their activity against adults, and only A. hirta showed an efficacy close to 90%. Eighteen extracts had an efficacy of up to 95% against larvae at a 40% concentration, seven extracts were effective at 20%, and only one (Sebastiana hispida was effective at a 5% concentration.

  4. Plants used traditionally to treat malaria in Brazil: the archives of Flora Medicinal

    Botsaris Alexandros S

    2007-05-01

    Full Text Available Abstract The archives of Flora Medicinal, an ancient pharmaceutical laboratory that supported ethnomedical research in Brazil for more than 30 years, were searched for plants with antimalarial use. Forty plant species indicated to treat malaria were described by Dr. J. Monteiro da Silva (Flora Medicinal leader and his co-workers. Eight species, Bathysa cuspidata, Cosmos sulphureus, Cecropia hololeuca, Erisma calcaratum, Gomphrena arborescens, Musa paradisiaca, Ocotea odorifera, and Pradosia lactescens, are related as antimalarial for the first time in ethnobotanical studies. Some species, including Mikania glomerata, Melampodium divaricatum, Galipea multiflora, Aspidosperma polyneuron, and Coutarea hexandra, were reported to have activity in malaria patients under clinical observation. In the information obtained, also, there were many details about the appropriate indication of each plant. For example, some plants are indicated to increase others' potency. There are also plants that are traditionally employed for specific symptoms or conditions that often accompany malaria, such as weakness, renal failure or cerebral malaria. Many plants that have been considered to lack activity against malaria due to absence of in vitro activity against Plasmodium can have other mechanisms of action. Thus researchers should observe ethnomedical information before deciding which kind of screening should be used in the search of antimalarial drugs.

  5. Destruction and management of Mount Kenya`s forests

    Bussmann, R.W. [Bayreuth Univ. (Germany). Fakultaet fuer Biologie, Chemie und Geowissenschaften

    1996-08-01

    This article presents data on the destruction of the montane forests on Mount Kenya. The material was obtained during field-work for a phytosociological study in 1992-1994. Special emphasis was given to the observation of regeneration patterns and succession cycles within the different forest communities, with regard to the impact of humans and big game. Although private tree planting is reducing the fuelwood deficit in Kenya, large parts of the 200 000 ha of Mount Kenya`s forests - the largest natural-forest area in the country - are heavily impacted by among other things illegal activities. The wet camphor forests of the south and southeast mountain slopes are being destroyed at an alarming speed, by large-scale selective logging of Ocotea usambarensis and marihuana cultivation. The drier Juniperus procera are also logged, but are even more endangered by the new settlement schemes. The large elephant population does not affect forest regeneration; whereas browsing and chaffing by buffaloes inhibits regeneration of the dry forests, and damages many trees. Suggestions are presented for better management of the forest resources. 12 refs, 1 fig

  6. Ethnopharmacological studies of antimicrobial remedies in the south of Brazil.

    de Souza, G Coelho; Haas, A P S; von Poser, G L; Schapoval, E E S; Elisabetsky, E

    2004-01-01

    This study reports the antimicrobial evaluation of the species most commonly used in Rio Grande do Sul (RS), the southernmost state of Brazil, for treating conditions likely to be associated with microorganisms. A four-stage process of documentation and evaluation was conducted: (a). review of RS ethnobotanical studies; (b). analysis of traditional uses; (c). literature survey on phytochemical and pharmacological data; (d). microbiological screening of selected plants. From the 149 species initially identified, 49 were cited as being used for microbial associated conditions in at least two other regions in RS, and 18 were further selected for screening. The crude methanol extract of these 18 plants were evaluated against seven microorganisms using the diffusion agar test. Extracts from Chaptalia nutans, Cordia monosperma, Echinodorus grandiflorus, Eugenia uniflora, Leonurus sibiricus, Luehea divaricata, Malva sylvestris, Ocotea odorifera, Parapiptadenia rigida, Pluchea sagittalis, Psidium cattleyanum and Senna neglecta were active against at least one microorganism. Although preliminary, these results are useful for rationalizing the use of medicinal plants in established systems of traditional medicine in primary health care.

  7. Coanatomical, developing and comparative analysis of 40 wood species belonging to two associations in colombian Andes highland forest

    Polanco Tapia Cesar; Grande Pulido Diana Carolina

    2009-01-01

    In this paper we conducted a relationship of the timber found with ecological aspects arising from an earlier study of the characterization, structure and floral composition practiced in the Carpatos Forest Reserve, bordering the site from which wood samples were obtained. This comparison shows a strong link between the microscopic anatomical characteristics of vegetal species with the type of association to which they belong. For example, characters such as the grouping form, the type of perforated and intervessel pits, height, number of cells wide, stratification and type of cells that make up the radio and type fiber, show a greater degree of change in the exclusive species of Ocotea callophylla-Weinmannietum pinnatae (OW) association, while the same characters show minor changes in the exclusive species of Clusia multiflorae - Weinmannietum balbisianae(CW) association. The evolution of the timber was identified through an index that suggests the research based on references like Carlquist (2001) and Leon (2001), and its relationship with the plant associations found in the study area is argued.

    Full Text Available This study was conducted at the campus of the Federal University of Lavras, Minas Gerais state, in an area of 7.56ha which in earlier times was planted with Anadenanthera peregrina. It aimed to describe the floristic composition of the site so asto provide a theoretical basis to assist future local management interventions. A total of 81 plots, each measuring 10x10m, wereallocated and arranged in such way as to cover as much apparent variation in the physiognomic gradient of the vegetation as possible.All individuals with DBH (diameter at breast height > 5.0 cm were recorded. Each individual had their DBH and height recorded.Diversity was assessed using Shannon, Pielou and Jentsen indices and compared to adjacent areas and to other areas with similarhistory of land use. The sampling procedure recorded 1,180 individuals, distributed among 25 families and 66 species. The familypresenting the largest number of recorded species was Fabaceae, with 16 species (24.24%. The genera presenting the greatest floristicrichness were Casearia, with four species, Machaerium and Rollinia, each with three species, and Anadenanthera, Tapirira, Cordia,Protium, Inga, Ocotea, Miconia, Cedrela and Myrcia, each with two species.

  10. Do variations in the composition and structure of vegetation allow floristic groups to be detected in a subtropical moist forest in southern Brazil?

    João Paulo de Maçaneiro

    2016-12-01

    Full Text Available Variations in vegetation based on topographic location have become an interest of researchers. However, few studies have verified floristic associations related to the topographic position of a slope. In this work, we analyzed if variations in vegetation allow floristic groups to be detected in a subtropical moist forest. The vegetation was sampled in 25 plots of 400 m² distributed systematically, where individuals with a DBH ≥ 5.0 cm were measured. We sampled 1,727 individuals and 144 species. The NMDS ordination segregated three groups based on the topographic position of the slope (Monte Carlo, P ≥ 0.05; ANOSIM, P < 0.001. Euterpe edulis and Sloanea guianensis were notable in the lower and middle sections of the slope, whereas Ocotea aciphylla and Alchornea triplinervia were notable in the upper section. Some species were indicators of the analyzed sectors, such as Actinostemon concolor and Alsophila setosa in the lower section, Cyathea corcovadensis and Rudgea recurva in the middle section, and Myrcia pulchra and Podocarpus sellowii in the upper section. Our results indicate that the floristic and structural variations observed by Veloso and Klein (1959 and Klein (1980; 1984 for Vale do Itajaí in Santa Catarina are statistically valid today, because we verified the formation of different groups according to the topographic position of the slope.

    Full Text Available Species identification and their market value and price evolution since the colonization time of the remnants of the Brazilian Semi-Evergreen Forest (Floresta Estacional Decidual do Rio Uruguai for potential timber production was assessed through 41 questionnaires, applied to timbermen and settlers from the surrounding region. The diversity of species for timber production commonly known by the people reached 63. From the 15 predominant species is relevant to mention Apuleia leiocarpa, Parapiptadenia rigida, Balfourodendron riedelianum, Nectandra megapotamica, Patagonula americana, Luehea divaricata, Cedrela fissilis, Ocotea diospyrifolia, Holocalyx balansae, Myrocarpus frondosus, Cabralea canjerana and Peltophorum dubium. The species with the highest commercial value were: Cordia trichotoma, Cedrela fissilis, Myrocarpus frondosus and Balfourodendron riedelianum. Data from the interviews suggest that several species from the Lauraceae family and Schefflera morototoni, Aralia warmingiana, Machaerium stipitatum, Chrysophyllum marginatum had an increment in use and commercial value during the last 15 years. Changing in the commercial value of a species was pointed out as due not only to the timber quality but also to the amount of the timber availability. Overall, it was detected that the species values changed across time and that the timber industry found several ways to adapt to the demands of forest products.

    Full Text Available This study aimed to characterize the influence of the soil and topography in the tree component of the fragments, in around the Divisa Reservoir, in the region of the Campos de Cima da Serra, Southern Brazil. The vegetation survey was conducted in four fragments, with each plot (10 x 20 m performed the identification and measurement of the circumference at breast height (CAP of subjects with CAP ≥ 30 cm. The vegetation data were subjected to cluster analysis. In addition, environmental variables were obtained as an average slope of plots and soil samples at 0-20 cm depth. The correlation between vegetation data and environmental data was performed by means of Canonical Correspondence Analysis. The soil physical characteristics showed no influence on the groups formed and species. In the geldings, the constant presence of cattle influenced negatively the structure of the understory, as well as the chemical characteristics of the soil. Aluminium and aluminum saturation have higher influenced on the predominant species of riparian vegetation as influenced copper and sulfur species present in geldings. Species such as Araucaria angustifolia, Eugenia uruguayensis, Blepharocalyx salicifolius, Calyptranthes concinna, Lithraea brasiliensis, Myrsine coriacea, Ocotea pulchella and Sebastiania commersoniana are adapted to riparian and can be used in the recovery and enrichment of these environments.

The objective of this study was to describe the diversity and structure of a forest remnant of Seasonal Submontane Deciduous Forest located in the municipality of São João do Oeste, Santa Catarina state. For the inventory, we demarcated 102 sampling units of 10 × 10 m, continuously arranged in a grid of 6 × 17 plots, in which all plants of the arborescent-arboreal sinusiae with perimeter at breast height (PBH ≥ 15 cm were sampled. We surveyed 1441.18 living trees and 93.14 standing dead plants per ha. The 79 species found belong to 61 genera and 33 families. Sorocea bonplandii , Nectandra megapotamica , Inga marginata , Ocotea diospyrifolia and Trichilia claussenii presented the highest importance value indexes. The Shannon diversity index (H’ was 3.21 and the Pielou equability (J’ was 0.735. The vertical structure of the vegetation sampled was divided into treelets (2-11 m, canopy (12-17 m and emerging trees (18-25 m. The studied forest fragment is an important reference ecosystem for the implementation of strategies for preservation, management and restoration of seasonal forests.

    Natural products, including those derived from plants, have largely contributed to the development of therapeutic drugs. Glutamate is the main excitatory neurotransmitter in the central nervous system and it is also considered a nociceptive neurotransmitter, by acting on peripheral nervous system. For this reason, in this study we investigated the effects of the hydroalcoholic extracts from Drymis winteri (polygodial and drimanial), Phyllanthus (rutin and quercetine), Jathopha elliptica (jatrophone), Hedyosmum brasiliense (13HDS), Ocotea suaveolens (Tormentic acid), Protium kleinii (alphabeta-amyrin), Citrus paradise (naringin), soybean (genistein) and Crataeva nurvala (lupeol), described as having antinociceptive effects, on glutamatergic transmission parameters, such as [(3)H]glutamate binding, [(3)H]glutamate uptake by synaptic vesicles and astrocyte cultures, and synaptosomal [(3)H]glutamate release. All the glutamatergic parameters were affected by one or more of these compounds. Specifically, drimanial and polygodial presented more broad and profound effects, requiring more investigation on their mechanisms. The putative central side effects of these compounds, via the glutamatergic system, are discussed.

  15. Anesthetic activity of Brazilian native plants in silver catfish (Rhamdia quelen

    Lenise de Lima Silva

    Full Text Available There is an increasing demand for inexpensive and safe anesthetics that can reduce fish stress caused by some procedures such as capture and handling. In this context, the present study evaluated the potential of essential oils (EO of three Brazilian native plants (Hesperozygis ringens, Lippia sidoides and Ocotea acutifolia as anesthetics for the silver catfish - Rhamdia quelen. Moreover, an analysis was made of the chemical composition of these oils and their influence on stress parameter. EO of H. ringens and O. acutifolia were effective as anesthetics, without behavioral side effects. EO of O. acutifolia (150 µL L-1 promoted an increase in blood glucose level. Regarding to the composition, pulegone accounts for 96.63% of the EO of H. ringens, and caryophyllene oxide amounts to 56.90% of the EO of O. acutifolia. Two chemotypes, thymol and carvacrol (68.40% and 67.89%, respectively were verified for EO of L. sidoides. Both samples of EO of L. sidoides showed anesthetic activity in silver catfish, but exposure also caused loss of mucus and mortality. Thus, only the EO of H. ringens and O. acutifolia are advised for anesthetic use

  16. Categorizing words using 'frequent frames': what cross-linguistic analyses reveal about distributional acquisition strategies.

    Chemla, Emmanuel; Mintz, Toben H; Bernal, Savita; Christophe, Anne

    2009-04-01

    Mintz (2003) described a distributional environment called a frame, defined as the co-occurrence of two context words with one intervening target word. Analyses of English child-directed speech showed that words that fell within any frequently occurring frame consistently belonged to the same grammatical category (e.g. noun, verb, adjective, etc.). In this paper, we first generalize this result to French, a language in which the function word system allows patterns that are potentially detrimental to a frame-based analysis procedure. Second, we show that the discontinuity of the chosen environments (i.e. the fact that target words are framed by the context words) is crucial for the mechanism to be efficient. This property might be relevant for any computational approach to grammatical categorization. Finally, we investigate a recursive application of the procedure and observe that the categorization is paradoxically worse when context elements are categories rather than actual lexical items. Item-specificity is thus also a core computational principle for this type of algorithm. Our analysis, along with results from behavioural studies (Gómez, 2002; Gómez and Maye, 2005; Mintz, 2006), provides strong support for frames as a basis for the acquisition of grammatical categories by infants. Discontinuity and item-specificity appear to be crucial features.

    2016-01-01

    A continuous stirred microbial electrochemical reactor (CSMER), comprising of a complete mixing zone (CMZ) and microbial electrochemical zone (MEZ), was used for brewery wastewater treatment. The system realized 75.4 ± 5.7% of TCOD and 64.9 ± 4.9% of TSS when fed with brewery wastewater concomitantly achieving an average maximum power density of 304 ± 31 m W m−2. Cascade utilization of organic matters made the CSMER remove a wider range of substrates compared with a continuous stirred tank reactor (CSTR), in which process 79.1 ± 5.6% of soluble protein and 86.6 ± 2.2% of soluble carbohydrates were degraded by anaerobic digestion in the CMZ and short-chain volatile fatty acids were further decomposed and generated current in the MEZ. Co-existence of fermentative bacteria (Clostridium and Bacteroides, 19.7% and 5.0%), acetogenic bacteria (Syntrophobacter, 20.8%), methanogenic archaea (Methanosaeta and Methanobacterium, 40.3% and 38.4%) and exoelectrogens (Geobacter, 12.4%) as well as a clear spatial distribution and syntrophic interaction among them contributed to the cascade degradation process in CSMER. The CSMER shows great promise for practical wastewater treatment application due to high pre-hydrolysis and acidification rate, high energy recovery and low capital cost. PMID:27270788

Diez días antes, Humberto Gómez, a la cabeza de una banda armada, se había tomado la población de Arauca. Por lo común, acontecimientos de esta índole poco conmocionaban a la capital. Arauca, aldea situada en la frontera con Venezuela, en medio de extensas llanuras tropicales y carente inclusive de comunicación telegráfica con Bogotá, era refugio favorito de los malhechores, que habitualmente desafia bancon impunidad las leyes de ambos países.

Indispensable para todos los que deseen entender la nueva lengua revolucionaria ["New Philosophical-Democratic Vocabulary. Indispensable for All Those Who Wish to Understand the New Revolutionary Language"], by the Jesuit Lorenzo Ignazio Thjulen (Gothenburg, 1746-Bologna, 1833, as well as the impact it had on the press and pamphlet-writing of the time. 1834 was a crucial year in the political history of the First Federal Republic, for it saw the confrontation between Valentín Gómez Farías' reform project and the anti-liberal reaction against it. Thjulen's dictionary, conceived and written within the Catholic counter-Enlightenment tradition, provided rationales for those challenging Gómez Farías' disentitling and anti-corporate project. Thjulen countered the language of revolution with the language of counter-Enlightenment, so the dissemination of his ideas in 1834 Mexico allows us to further understand the doctrinal and political tensions between liberals, conservatives, and Catholics during the first post-viceregal decades.

  6. Ethnomedicines used in Trinidad and Tobago for reproductive problems.

    2007-03-15

    Throughout history women have tried to control or enhance their fertility using herbal remedies, with various levels of societal support. Caribbean folk medicine has been influenced by European folk medicine, either through the early Spanish and French settlers or through the continuous immigration of Spanish-speaking peoples from Venezuela. Some folk uses are ancient and were documented by Galen and Pliny the Elder. Thirty respondents, ten of whom were male were interviewed from September 1996 to September 2000. The respondents were obtained by snowball sampling, and were found in thirteen different sites, 12 in Trinidad (Paramin, Talparo, Sangre Grande, Mayaro, Carapichaima, Kernahan, Newlands, Todd's Road, Arima, Guayaguayare, Santa Cruz, Port of Spain and Siparia) and one in Tobago (Mason Hall). Snowball sampling was used because there was no other means of identifying respondents and to cover the entire islands. The validation of the remedies was conducted with a non-experimental method. Plants are used for specific problems of both genders. Clusea rosea, Urena sinuata and Catharanthus roseus are used for unspecified male problems. Richeria grandis and Parinari campestris are used for erectile dysfunction. Ageratum conyzoides, Scoparia dulcis, Cucurbita pepo, Cucurbita maxima, Gomphrena globosa and Justicia pectoralis are used for prostate problems.

    Full Text Available É grande a demanda por estudos ecológicos em florestas que possam embasar trabalhos de recuperação, conservação da biodiversidade e apoio à legislação ambiental. Entre esses estudos, primordialmente está o levantamento da flora. Nesse sentido, este trabalho teve como objetivo determinar a composição florística de um trecho da Reserva da Biologia, em Viçosa, MG, em regeneração natural há 80 anos, bem como realizar uma análise comparativa com outros trabalhos conduzidos na região, fornecendo, assim, informações que poderão embasar estudos sobre recuperação e conservação da biodiversidade dos fragmentos de Floresta Estacional Semidecidual. Os dados florísticos foram obtidos mediante a amostragem fitossociológica em 1 ha, pelo método de parcelas contíguas, em que todos os indivíduos arbóreos com circunferência de tronco >15 cm a 1,30 m do solo foram amostrados. Registraram-se 130 espécies, distribuídas em 94 gêneros, pertencentes a 38 famílias botânicas. A análise desses dados conjuntamente com de outros levantamentos realizados em trechos distintos da Reserva da Biologia, no campus da UFV, denota a marcante influência de variáveis ambientais locais (topografia, declividade, face de exposição solar e disponibilidade hídrica na distribuição da riqueza florística desse fragmento. Casearia decandra, Guapira opposita, Apuleia leiocarpa, Dalbergia nigra, Jacaranda macratha, Matayba elaeagnoides, Piptadenia gonoacantha, Bathysa nicholsonii, Carpotroche brasiliensis, Luehea grandiflora, Mabea fistulifera, Ocotea odorifera, Sorocea bonplandii e Zanthoxylum rhoifolium foram as espécies de maior ocorrência nos fragmentos estudados na região de Viçosa e adjacências, apresentando potencial para uso na recuperação florestal de áreas degradadas.There is a great demand for ecological studies on forests focusing on biodiversity conservation and establishment of environmental laws.

    Rangel Chávez, José de Jesús; Espinosa Martínez, Cynthia; Medina Serpa, Aldo Uzziel

    The onset of nasal breathing sets a genetically determined impulse to aerate the face cavities or paranasal sinuses, which in turn initiate its growth creating the useful trafficable space for air during the development of the midface. Considering the evidence that the upper airway obstruction has a primary role in the pathogenesis of respiratory sleep disorders, any condition that causes a permanent difficulty to the nasal airflow during breathing will cause hypo-development of the required amplitude in this airway, reducing the growth stimulation of the sinus cavities and altering the development of the midface as a whole.

Gómez de Avellaneda: Sab (the Cuban/Spanish equivalent of Uncle Tom’s Cabin), written between 1836 and 1839 and published 1841 in Spain. I will argue that the sentimentalism of Sab is of a revolutionary kind, based in a conception of natural law and that its aim is a radical transformation of social...... hierarchies. The paper will be divided into three parts: 1. First I will discuss what sentimentalism is and its relation to politics and especially abolitionism in the 19th century. 2. Then I will analyze Sab’s genre trying to establish the different functions of sentimentality, discussing the tragic modes...

  15. Audit firm tenure and qualified opinions: New evidence from Spain

    Josep García Blandón

    2013-06-01

    Full Text Available The 2010 Green Paper on Audit Policy by the European Commission has explicitly questioned the sufficiency of audit rotation rules established by European Union Members to guarantee auditor independence. In addition, the Paper clearly states that more research is needed regarding the effects of long audit tenures on independence. In this article, we have replicated the research by Ruiz-Barbadillo, Gómez-Aguilar, and Biedma (2005 about the effects of audit firm tenure on independence with more updated data. However, unlike them, we have performed panel data estimations instead of pooled regression. Our approach allows for a better control of individual unobserved heterogeneity, thus reducing potential problems caused by omitted variable bias. While Ruiz-Barbadillo et al. reported an unexpected positive effect of tenure on the likelihood of audit qualifications, we do not show any significant effect of tenure on the opinion of the audit report. Our results are robust to various sensitivity analyses.

    It has been reported in literature that self-esteem increases in patients who pass from continuous ambulatory peritoneal dialysis to renal transplantation. However, our clinical observations in the Department of Nephrology of Hospital Infantil de México Federico Gómez indicate otherwise. Therefore, we carried out this research on 60 patients, children and adolescents, male and female between the ages from 8 to 15 years old, and we applied them the Coopersmith self-esteem questionnaire, which has been validated in mexican population. These findings indicate that the social environment continuous ambulatory peritoneal dialysis patients feel more adapted than patients in renal transplant (p = 0.05). However it was also observed that these patients tried to show a better image on their situation through compensatory mechanisms (defense p = 0.03). It was concluded that it would be necessary to follow the adaptation of the transplanted patients, in order to help them achieve complete rehabilitation.

First, I will identify the context that surrounded the publication of El Nuevo Mercurio, Mundial Magazine, La Revista de América y la Revue Sud-Américaine. Second, by considering the reviews as well as the letters and memoirs of the aforementioned Latin American writers living in Paris in the early XX Century, I will focus on the common features of their publishing projects. Henceforth, I will tackle down the specifics aspects of Latin American reviews in Paris –such as their sub-continental and international mediating role–, and I will relate them to some of the cultural and social processes of the period.

    2002-06-01

    The geosciences contribution along the 50 years of the Revista de Biología Tropical had been scarcity and episodic. Until now there are 2374 papers but only 21 (0.88%) have some relation with geological sciences. It's possible to recognize two periods with geological contributions, one between 1963 and 1978. It's appropriate to underline the importance of the biologist L. D. Gómez with his contributions about Costa Rican Paleobotanic in this period. The other period includes from 1988 to the present, and it's typified by an increase of biologist and geologist participation in different topics regarding with geosciences. Foreign and national researches are in the same ratio and belong from several countries like Costa Rica, México and Dominican Republic. The subjects are concerning mainly about fossil taxonomy (Paleontology: 81%), only 19% are related with geological topics. Such distribution could be explained because the affinity between the fossil studies and the biological sciences.

  4. [Scientific reductionism and social control of mind. Part II].

    Viniegra Velázquez, Leonardo

    In the second part of this essay, the progressive subordination of scientific endeavor and knowledge of business and profit is pointed out. For instance, the way facts are prioritized over concepts and ideas in scientific knowledge can translate into technological innovation, central to enterprise competitiveness and key to social mechanisms of control (military, cybernetic, ideological). Overcoming the scientific reductionism approach indicates recognizing the need to define progress in another way, one that infuses scientific knowledge with real liberating and inquisitive power. Power is essential in the search for a more collaborative, inclusive and pluralistic society where respect for human dignity and care for the ecosystem that we live in are prioritized.

    Chikungunya fever is a tropical vector-borne disease that has been spreading rapidly around the world during the last 10 years, and which has been usually misdiagnosed as dengue. Nowadays, this disease is increasing in Mexico, mainly in the southern and central zones of the country, being significantly more common in women, children and young adults (28% in<20 years of age). The classical presentation includes fever, arthralgia, polyarthritis, back-pain, and skin rashes. Although symptoms and treatment are similar to those for dengue, there are key clinical features to differentiate these two diseases. Copyright © 2016 Hospital Infantil de México Federico Gómez.

    Pietro Pisano

    2014-01-01

    Full Text Available From the study of articles published in Colombian magazines (particularly Cromos magazine in the second half of the twentieth century, this article proposes the analysis of some representations about upward mobility of black people. Consideration is given to the stories of some characters at different times: the judge Jose Antonio Camacho, the boxer Kid Pambelé, the model Laura Mosquera and the pianist Teresa Gómez. Although they emerged in different professional contexts, narratives about their paths have in common the emphasis on how the class representations articulated with the race and gender ones and were used to show the difficulty for a black person to be inserted in a social context different from the popular sectors, showing both their alleged incompatibility with the values of the middle class as well as the inability to fully integrate into a society dominated by whites.

There was also a relatively high variability within the same soil management and soil type class, indicating farm to farm variability in conditions and history of soil management. Based on this dataset two different approaches were taken to: A) evaluate the risk of soil degradation based on a limited set of soil properties, B) assess the effect of changes in SMS on soil biodiversity by using terminal restriction profiles (TRFs) derived from T-RFLP analysis of amplified 16S rDNA as. The results indicates the potential of both approaches to assess the risk of soil degradation (A) and the impact on soil biodiversity (B) upon appropriate benchmarking to characterize the interaction between soil management and soil type References Álvarez, S., Soriano, M.A., Landa, B.B., and Gómez, J.A. 2007.

  12. Art and aesthetics in the Minutogramas of Jorge Oteiza

    José Javier Azanza López

    2018-02-01

    Full Text Available During his stay in Buenos Aires in 1939, Jorge Oteiza promoted the artistic information service The art walk, a consequence of which are his Minutogramas. They are close to the comic aesthetic, show a remarkable interest in graphic design, and display a discourse that echoes Surrealism and the “ramonismo” of Ramón Gómez de la Serna. In this way, the sculptor provides some keys to understanding his aesthetic thinking: his belief in the universal values of Geometry following in the footsteps of Leonardo; Nature as the foundation for sculptural creation which he discovers in Maillol, Zadkine, Alberto and Erzia; his admiration for El Greco, Velázquez and Goya as Hispanic models; the recognition of Cézanne as the father of Contemporary Art and the teachings of Hans Arp, constitute some of the themes found in his Minutogramas, in which he also manifests his humanistic dimension in several areas of knowledge.

  13. Omics techniques and biobanks to find new biomarkers for the early detection of acute lymphoblastic leukemia in middle-income countries: a perspective from Mexico.

    Aguirre-Guillén, William Alejandro; Angeles-Floriano, Tania; López-Martínez, Briceida; Reyes-Morales, Hortensia; Zlotnik, Albert; Valle-Rios, Ricardo

    Acute lymphoblastic leukemia (ALL) affects the quality of life of many children in the world and particularly in Mexico, where a high incidence has been reported. With a proper financial investment and with well-organized institutions caring for those patients, together with solid platforms to perform high-throughput analyses, we propose the creation of a Mexican repository system of serum and cells from bone marrow and blood samples derived from tissues of pediatric patients with ALL diagnosis. This resource, in combination with omics technologies, particularly proteomics and metabolomics, would allow longitudinal studies, offering an opportunity to design and apply personalized ALL treatments. Importantly, it would accelerate the development of translational science and will lead us to further discoveries, including the identification of new biomarkers for the early detection of leukemia.

  18. Epstein-Barr virus-associated hemophagocytic lymphohistiocytosis: response to HLH-04 treatment protocol.

    Jiménez-Hernández, Elva; Martínez-Villegas, Octavio; Sánchez-Jara, Berenice; Martínez-Martell, María Angélica; Hernández-Sánchez, Beatriz; Loza-Santiaguillo, Paloma Del Rocío; Pedro-Matías, Eduardo; Arellano-Galindo, José

    Hemophagocytic syndrome, macrophage activation syndrome, reactive histiocytosis or hemophagocytic lymphohistiocytosis (HLH) represent a group of diseases whose common thread is reactive or neoplastic mononuclear phagocytic system cells and dendritic cell proliferation. We present a case of an HLH probably associated with Epstein-Barr virus (EBV) in a 4-year-old male patient treated with HLH-04 protocol. Viral etiology in HLH is well accepted. In this case, clinical picture of HLH was assumed secondary to EBV infection because IgM serology at the time of clinical presentation was the only positive factor in the viral panel. Diagnosis of HLH is the critical first step to successful treatment. The earlier it is identified, the less the tissue damage and reduced risk of multiple organ failure, which favors treatment response. Copyright © 2016 Hospital Infantil de México Federico Gómez.

  20. Description and notes on natural history of a new species of Parosus Sharp, 1887 (Coleoptera, Staphylinidae, Oxytelinae) living in floral bracts of Columnea medicinalis L. (Gesneriaceae).

    LÓpez-garcÍa, Margarita M; MarÍn-gÓmez, Oscar H

    2018-03-16

    A new species of the recently revised genus Parosus is described, P. amayae López-García Marín-Gómez sp. nov., from adult and larval specimens collected in bracts of Columnea medicinalis in the Natural Reserve Río Ñambí (Southwestern Colombia). Observations on the interaction with the plant, subsocial behavior, and population density are presented and discussed. Adults and larvae apparently live together and feed on eggs and larvae of flies that develop inside the decomposing fruits of C. medicinalis. The new species is illustrated by color habitus photos, as well as its L1 and L3 larvae, male and female genitalia are depicted by line drawings.

  1. The atomic conflict

    Mez, L.

    1981-01-01

    This book provides a general view at the atomic programmes of several countries and makes an attempt to unmask the atomic industrial combines with their interlockings. The governments role is analysed as well as the atomic policy of the parties, union-trades and associations. Then, the anti-atomic movements in those countries, their forms of resistance, the resonance and the alternative proposals are presented. The countries concerned are Australia, the FRG, COMECON, Danmark, the EG, Finland, France, Great Britain, Ireland, Japan, the Netherlands, Norway, Austria, Sweden, Switzerland, Spain and the USA. For the pocket book version, Lutz Mez adds an updating epilogue which continues with the developments until springtime 1981. (orig./HP) [de

    Full Text Available New records are provided for three species of little-known pagurids. All the material reported was collected by the R/V “El Puma” in the central Gulf of California during the GUAYTEC II cruise. New material is reported for Iridopagurus haigae García-Gómez, 1983, Enallopagurus spinicarpus (Glassell, 1937, and Solenopagurus diomedeae (Faxon, 1893, and these two latter species are redescribed. A new species of hermit crab of the genus Pagurus Fabricius, 1775, is described and illustrated in detail. Among the eastern Pacific species of Pagurus, this new species resembles Pagurus meloi Lemaitre and Cruz Castaño, 2004, P. imarpe Haig, 1974 and P. delsolari Haig, 1974, but differs from these three species in the armature and setation of the chelipeds and second and third pereopods, the shape and armature of the telson, and the number of rows of scales on pereopodal rasp and the presence of a preungual process.

  5. El eufemismo léxico del discurso político y sus efectos cognitivos

    Nuria Barranco Flores

    2017-06-01

    Full Text Available In some studies about euphemism it has been pointed out that politicians usually resort to euphemistic expressions to conceal unpleasant facts that could damage their own image (Rodríguez González, 1991; Roldán Pérez, 2003; Crespo Fernández, 2005a. This article examines euphemism from a pragmatic-cognitive perspective (Chamizo Domínguez & Sánchez Benedito, 2000; Casas Gómez, 2009; Sytnyk, 2014 and explains some mental effects derived from a series of euphemistic expressions which have recently been used in Spanish political discourse. In particular, the paper suggests the existence of three phenomena which have an influence on the addressee’s mental representation of reality: lexical framing, blocked access to the referent and conceptual stigmatization.

  12. Silencing of voices in a Swedish science classroom

    Ramos de Robles, S. Lizette

    2018-03-01

    From a sociocultural perspective, I discuss data from a Swedish science classroom presented in María Gómez's article "Student Explanations of their Science Teachers' Assessments, Grading Practices, and How they learn Science". In this discussion, I focus on the need to change existing conceptions of assessment in the teaching and learning of science. Next, I talk about the importance of taking into consideration the dialectic between agency and passivity as filters in order to understand what student silence may signify in science classes as well as in relation to their perceptions of assessment. I conclude with the importance of the teacher's role in developing formative assessment, along with the challenges in developing assessments which transform science education into a relevant field of knowledge for both students and society at large.

  15. [Incontinentia pigmenti with defect in cellular immunity].

    Zamora-Chávez, Antonio; Escobar-Sánchez, Argelia; Sadowinski-Pine, Stanislaw; Saucedo-Ramírez, Omar Josué; Delgado-Barrera, Palmira; Enríquez-Quiñones, Claudia G

    Incontinentia pigmenti is a rare, X-linked genetic disease and affects all ectoderm-derived tissues such as skin, appendages, eyes, teeth and central nervous system as well as disorders of varying degree of cellular immunity characterized by decreasing melanin in the epidermis and increase in the dermis. When the condition occurs in males, it is lethal. We present the case of a 2-month-old infant with severe incontinentia pigmenti confirmed by histological examination of skin biopsy. The condition evolved with severe neurological disorders and seizures along with severe cellular immune deficiency, which affected the development of severe infections and caused the death of the patient. The importance of early clinical diagnosis is highlighted along with the importance of multidisciplinary management of neurological disorders and infectious complications.

    2010-04-01

    Full Text Available Rural tourism businesses have experienced a very remarkable growth in recent times, providing regions with large opportunities to develop economically and socially. Part of the success of these businesses is due to the search of quality in the services they provide. In this work the influence of various dimensions of total quality orientation on staff satisfaction, communication and commitment in this tourist sector are analysed. The sample was made up of staff from hotels and restaurants in the mountainous area of “Sierra de Aracena y Picos de Aroche” in the province of Huelva, using Gómez-Bernabeu’s Quality and Culture Questionnaire for data collection. By means of linear regressions it was observed that the dimensions of acknowledgement and continuous improvement have an influence on communication, while development and training of human resources would be the best predictor of job satisfaction. Nevertheless, no conclusive data were obtained regarding organizational commitment.

  7. Adult nest attendance and diet of nestling Resplendent Quetzals (Pharomachrus mocinno) in the Talamanca Mountains of southern Cosa Rica

    Carleton, Scott A.

    2016-01-01

    Resplendent Quetzals (Pharomachrus mocinno) inhabit mid to high elevation forests from southern Mexico to Panama. Lipid rich fruits from the Lauraceae family have been found to account for a large proportion of adult diet across their annual life cycle. To better understand the relationship between quetzals and Lauraceae during the breeding season, we studied food deliveries to nestlings in the Talamanca Mountains at San Gerardo de Dota, Costa Rica in the Rio Savegre watershed. Our study had four primary objectives: 1) determine parental contribution of males and females feeding nestling quetzals, 2) determine type of food delivered to nestling quetzals, 3) determine if deliveries of fruit items were related to their abundance and/or nutritional content and 4) determine if Lauraceae fruits made up a large proportion of nestling diets based on the high preference quetzals have displayed for fruits from this plant family. Hourly delivery rates were similar for the male and female (1.24 ± 0.68 and 1.44 ± 0.84). During the first 6 days, the largest proportion of the diet was animal prey; primarily lizards and beetles. After day 6, fruit rapidly became the dominant food item delivered to nestlings until fledging. The dominant number of fruits delivered to nestling quetzals were fruits from the Lauraceae family and included Ocotea holdrigeiana, Necatandra cufodontisii, and Aiouea costaricensis. All three had some of the highest protein and lipid content of all fruits delivered to nestlings. O. holdrigeiana had the highest protein and lipid content of all fruits delivered, had the lowest relative abundance, and was delivered more frequently than all other fruits. Conservation strategies for this species should take into account not just increasing available habitat, but also increasing habitat quality by focusing on species composition to provide abundant food plants for the Resplendent Quetzal to forage.

    The Araucaria Forests in southern Brazil are part of the Atlantic Rainforest, a key hotspot for global biodiversity. This habitat has experienced extensive losses of vegetation cover due to commercial logging and the intense use of wood resources for construction and furniture manufacturing. The absence of precise taxonomic tools for identifying Araucaria Forest tree species motivated us to test the ability of DNA barcoding to distinguish species exploited for wood resources and its suitability for use as an alternative testing technique for the inspection of illegal timber shipments. We tested three cpDNA regions (matK, trnH-psbA, and rbcL) and nrITS according to criteria determined by The Consortium for the Barcode of Life (CBOL). The efficiency of each marker and selected marker combinations were evaluated for 30 commercially valuable woody species in multiple populations, with a special focus on Lauraceae species. Inter- and intraspecific distances, species discrimination rates, and ability to recover species-specific clusters were evaluated. Among the regions and different combinations, ITS was the most efficient for identifying species based on the 'best close match' test; similarly, the trnH-psbA + ITS combination also demonstrated satisfactory results. When combining trnH-psbA + ITS, Maximum Likelihood analysis demonstrated a more resolved topology for internal branches, with 91% of species-specific clusters. DNA barcoding was found to be a practical and rapid method for identifying major threatened woody angiosperms from Araucaria Forests such as Lauraceae species, presenting a high confidence for recognizing members of Ocotea. These molecular tools can assist in screening those botanical families that are most targeted by the timber industry in southern Brazil and detecting certain species protected by Brazilian legislation and could be a useful tool for monitoring wood exploitation.

    The use of many traditional medicinal plants is often hampered by the absence of a proper biochemical characterization, essential to identify the bioactive compounds present. The leaves from five species endemic to the Macaronesian islands with recognized ethnobotanical applications were analysed: Apollonias barbujana (Cav.) Bornm., Ocotea foetens (Ainton) Baill, Prunus azorica (Mouill.) Rivas-Mart., Lousã, Fern. Prieto, E. Días, J.C. Costa & C. Aguiar, Rumex maderensis Lowe and Plantago arborescens Poir. subsp. maderensis (Dcne.) A. Hans. et Kunk.. Since oxidative stress is a common feature of most diseases traditionally treated by these plants, it is important to assess their antioxidant capacity and determine the molecules responsible for this capacity. In this study, the antioxidant capacity of these plants against two of the most important reactive species in human body (hydroxyl and peroxyl radicals) was determined. To trace the antioxidant origin total phenol and flavonoid contents as well as the polyphenolic profile and the amount of trace elements were determined. There was a wide variation among the species analysed in what concerns their total leaf phenol and flavonoid contents. From the High Performance Liquid Chromatography (HPLC) electrochemically detected peaks it was possible to attribute to flavonoids the antioxidant capacity detected in A. barbujana, O. foetens, R. maderensis and P. azorica extracts. These potential reactive flavonoids were identified for A. barbujana, R. maderensis and P. azorica. For R. maderensis a high content (7 mg g-1 dry weight) of L-ascorbic acid, an already described antioxidant phytomolecule, was found. A high content in selenomethionine (414.35 microg g-1 dry weight) was obtained for P. arborescens subsp. maderensis extract. This selenocompound is already described as a hydroxyl radical scavenger is reported in this work as also possessing peroxyl radical scavenging capacity. This work is a good illustration of

Tendo em vista a necessidade de se aprimorar conhecimentos sobre o crescimento de espécies em regiões subtropicais, o presente trabalho teve por objetivo monitorar o crescimento diamétrico intra-anual de espécies arbóreas em Colombo, Paraná. Em novembro de 2009 foram instaladas faixas dendrométricas em árvores adultas (de 15 a 25 indivíduos de 9 espécies dentre as mais frequentes em um remanescente de Floresta Ombrófila Mista. As medições de incremento diamétrico foram feitas mensalmente, até junho de 2011. Ocotea bicolor se diferenciou das outras espécies, apresentando crescimento superior e constante. Isto pode ser atribuído ao menor recobrimento da copa das árvores, favorecendo o acesso à luz pela espécie e consequentemente o seu crescimento. O maior crescimento de todas as espécies estudadas ocorreu no outono de 2011, estação antecedida por um inverno de baixa precipitação (inverno de 2010, em que a luminosidade esteve mais disponível para a produção fotossintética.

Objective: To evaluate cow’s milk protein allergy frequency in patients sensitized to them, attended at the consultation of Immunology and Allergy in the Hospital Infantil de México Federico Gómez, and its association with other atopic diseases. Material and method: A cross-sectional, analytical and descriptive study that reviewed medical records of patients aged 0-19 years, attended at the consultation of Immunology and Allergy in the Hospital Infantil de México Federico Gómez, from January 2010 to January 2013, sensitized to the cow’s milk protein by in vitro or in vivo studies, mediated or not by IgE, to determine its association with other atopic diseases during the course of their clinical evolution. Results: We included 252 patients with symptoms suggestive of cow’s milk protein allergy, which was diagnosed only in 15.1% by oral challenge. In relation to respiratory symptoms, about two-thirds of patients had rhinorrhea, nasal obstruction and nasal itching. Regarding gastrointestinal symptoms, about a third had abdominal pain, diarrhea and abdominal distension, being statistically significant. The most common dermatologic symptom, statistically significant, was xerosis. The most frequently associated atopic diseases were food allergy (76.3%, allergic rhinitis (65.8%, asthma (47.4% and atopic dermatitis (23%. Conclusions: The cow’s milk protein allergy can be associated with other atopic diseases, such as allergy to other foods, allergic rhinitis, asthma and atopic dermatitis.

    Full Text Available El objetivo del presente trabajo es reconstruir el perfil socioeconómico de los prestamistas abulenses que aparecen en el libro del notario Gómez González entre los años 1448 a 1451. Allí consta la existencia de unas setecientas operaciones de préstamo, de las cuales más de la mitad tienen como acreedores a un pequeño número de sujetos. A su vez, los mismos aparecen involucrados en numerosas actividades económicas adicionales. Se realiza en primer lugar una presentación del conjunto de las deudas consignadas, su distribución temporal, sus montos y de las características globales de prestamistas y prestatarios. Luego, se analizan las actividades de los acreedores más prominentes, utilizando para ello documentación complementaria del concejo de Ávila. En base a ello, por último, se intenta una reconstrucción del perfil social de este segmento de la sociedad concejil bajomedieval. The objective of this paper is to reconstruct the socio-economic profile of money-lenders in Ávila which appear in the books of the public notary, Gómez González, between 1448 and 1451. From this source, it is possible to identify close to seven hundred credit records, of which more than half belong to a small group of lenders. Furthermore, these creditors also appear taking part in many additional economic activities. First, we present a comprehensive examination of these loans, their chronological distribution, the monetary quantities and the general features of the lenders and the borrowers. Secondly, we analyze the activities of the most prominent lenders using supplementary documents from Ávila. Finally and based on this collected data, we intend to reconstruct the social profile of this group within late-medieval urban society.

  11. Groundwater discharge in high-mountain watersheds: A valuable resource for downstream semi-arid zones. The case of the Bérchules River in Sierra Nevada (Southern Spain).

    Aquifers in permeable formations developed in high-mountain watersheds slow down the transfer of snowmelt to rivers, modifying rivers' flow pattern. To gain insight into the processes that control the hydrologic response of such systems the role played by groundwater in an alpine basin located at the southeastern part of the Iberian Peninsula is investigated. As data in these environments is generally scarce and its variability is high, simple lumped parameter hydrological models that consider the groundwater component and snow accumulation and melting are needed. Instead of using existing models that use many parameters, the Témez lumped hydrological model of common use in Spain and Ibero-American countries is selected and modified to consider snow to get a simplified tool to separate hydrograph components. The result is the TDD model (Témez-Degree Day) which is applied in a high mountain watershed with seasonal snow cover in Southern Spain to help in quantifying groundwater recharge and determining the groundwater contribution to the outflow. Average groundwater recharge is about 23% of the precipitation, and groundwater contribution to total outflow ranges between 70 and 97%. Direct surface runoff is 1% of precipitation. These values depend on the existence of snow. Results are consistent with those obtained with chloride atmospheric deposition mass balances by other authors. They highlight the important role of groundwater in high mountain areas, which is enhanced by seasonal snow cover. Results compare well with other areas. This effect is often neglected in water planning, but can be easily taken into account just by extending the water balance tool in use, or any other, following the procedure that has being developed.

Subsequently, the so-called «other Generation of '27», following the leadership of Ramón, offered its thoughts on the scope of a completely humorous aesthetic approach. Until the 60's, we will not again encounter books on the issue: those of Evaristo Acevedo and Santiago Vilas.

En los últimos años, José Antonio Marina ha vuelto a abrir el debate a partir de la noción de ingenio. Este artículo se presenta como una revisión crítica de todas estas teorías.

  13. Inverting Coseismic TEC Disturbances for Neutral Atmosphere Pressure Wave

    Lee, R. F.; Mikesell, D.; Rolland, L.

    2017-12-01

    Research from the past 20 years has shown that we can detect coseismic disturbances in the total electron content (TEC) using global navigation space systems (GNSS). In the near field, TEC disturbances are created by the direct wave from rupture on the surface. This pressure wave travels through the neutral atmosphere to the ionosphere within about 10 minutes. This provides the opportunity to almost immediately characterize the source of the acoustic disturbance on the surface using methods from seismology. In populated areas, this could provide valuable information to first responders. To retrieve the surface motion amplitude information we must account for changes in the waveform caused by the geomagnetic field, motion of the satellites and the geometry of the satellites and receivers. One method is to use a transfer function to invert for the neutral atmosphere pressure wave. Gómez et al (2015) first employed an analytical model to invert for acoustic waves produced by Rayleigh waves propagating along the Earth's surface. Here, we examine the same model in the near field using the TEC disturbances from the direct wave produced by rupture at the surface. We compare results from the forward model against a numerical model that has been shown to be in good agreement with observations from the 2011 Van (Turkey) earthquake. We show the forward model predictions using both methods for the Van earthquake. We then analyze results for hypothetical events at different latitudes and discuss the reliability of the analytical model in each scenario. Gómez, D., R. Jr. Smalley, C. A. Langston, T. J.

  1. A simplified Excel tool for implementation of RUSLE2 in vineyards for stakeholders with limited dataset

    Gomez, Jose Alfonso; Biddoccu, Marcella; Guzmán, Gema; Cavallo, Eugenio

    2016-04-01

    Analysis with simulation models is in many situations the only way to evaluate the impact of changes in soil management on soil erosion risk, and the Revised Universal Soil Loss Equation RUSLE (Renard et al. 1997, Dabney et al. 2012) remains as the most widely used. Even with their relative simplicity compared to other, more process based, erosion models proper RUSLE calibration for a given situation outside the modelling community can be challenging, especially in situations outside of those widely covered in the USA. An approach pursued by Gómez et al. (2003) to overcome this problems for calibrating RUSLE, specially the cover-management factor, C, was to build a summary model using the equations defined by the RUSLE manual (Renard et al. 1997) but considering that the basic information required to calibrate the subfactors, such as soil surface roughness and ground cover, soil moisture, … were calculated (or taken from available sources) elsewhere and added to the summary model instead of calculated by the RUSLE software. This strategy simplified the calibration process as well as the understanding and interpretation of the RUSLE parameters and model behavior by on-expert users for its application in olive orchards under a broad range of management conditions. Gómez et al. (2003) build this summary model in Excel and demonstrated the ability to calibrate RUSLE for a broad range of management conditions. Later on several studies (Vanwalleghem et al., 2011, Marin, 2013) demonstrated how this summary model successfully predicted soil losses at hillslope scale close to those determined experimentally. Vines are one of the most extended tree crops covering a wide range of environmental and management conditions, and conceptually present in terms of soil conservation several analogies with olives especially in relation to soil management (Gomez et al., 2011). In vine growing areas, besides topographic and rainfall characteristics, the soil management practices

  2. Evaluating grass strips trapping efficiency of sediments and herbicides

    Burguet, Maria; Guzmán, Gema; de Luna, Elena; Taguas, Encarnación V.; Gómez, José Alfonso

    2016-04-01

    Water erosion and associated offsite contamination are major environmental risks in many Mediterranean crops such as olives or vineyards (Beaufoy, 2001; Gómez et al., 2011). The use of cover crops has been prescribed as a mitigation measure for both problems because permanent cover crops have demonstrated to reduce sediment and agrochemical loads (e.g. Gómez, 2009a, b). However, large uncertainty remains about its effectiveness degree to reduce sediment and agrochemical contribution to streams due to the limited number of available studies, and the large variability observed under field conditions (Taguas et al., 2012). Furthermore, the determination of sediment and herbicide sources using suitable sediment tracing/fingerprinting properties has been noted as one tool to evaluate the effectiveness and functioning of vegetated filters at the catchment scale (Koiter et al., 2013). The objectives of the present study were twofold: [1] to explore the combined use of natural and simulated rainfall and magnetic iron oxide in understanding the performance of vegetation strips on runoff and soil and herbicide losses at plot scale and, [2] to evaluate the effectiveness degree of vegetation strips in buffering sediment and herbicide from bare soil areas under different conditions compared to a control situation with no strips. This study encompasses six rainfall simulations under four different soil managements combining the use of a magnetic iron oxide as a sediment tracer to obtain a better understanding of the vegetation strips trapping efficiency. Three runoff plots of 6 m × 14 m were established in a 20% hillslope under a Fluvisol alluvial terrace. Each of the plots contained three bare strips tagged with magnetic iron oxide and three strips with Lolium multiflorum L. The soil management simulated scenarios were: immediately after sowing the vegetation cover (June 2011cover crop), with settled vegetation cover (June 2012cover crop), after 5 cm of deep ploughing

  3. A proposal for soil cover and management factor (C) for RUSLE in vineyards with different soil management across Europe

    The Revised Universal Soil Loss Equation RUSLE (Dabney et al., 2012) is commonly used to estimate rates of soil erosion caused by rainfall and its associated overland flow on cropland and many other disturbed and undisturbed lands. Several studies have been focused on the evaluation of erosion risk in vineyards across Europe, which has four countries, France, Italy, Spain and Portugal, among the world's top ten vine growers. Other European countries, such as Romania, Greece, Austria, Serbia and Hungary, also have significant surface devoted to vineyards (FAO, 2014). However, literature shows a wide variability among C factors from different sources (Auerswald and Schwab, 1999; Kouli et al., 2009; Novara et al., 2011; Pacheco et al., 2014; Rodrigo Comino et al., 2016) that complicates their interpretation and use outside the area where they were developed. Gómez et al. (2016) presented a simplified erosion prediction model based on RUSLE, ORUSCAL, to demonstrate the possibility to calibrate RUSLE for a broad range of management conditions in vineyards with limited datasets. This approach have already been pursued successfully in olives (Gómez et al. 2003, Vanwalleghem et al., 2011). This communication reports the results of an evaluation of the calibration strategies and model predictions of ORUSCAL using a long-term experiment dataset (Bidoccu et al., 2016) in a vineyard in Northern Italy, and its implementation to develop soil cover and management factors (C) in three different soil, climate and management conditions across Europe: Southern Spain, Northern Italy and Austria. The communication, furthermore, explores and discusses of the application of the ORUSCAL model to additional vineyards areas in France and Romania in the context of the Vinedivers project (www.vinedivers.eu).

    albitization. Biotites are not or weakly chloritized. However, these "unaltered" (or primary) granites are strongly weathered into granite boulders embedded in grus by the present-day climatic conditions. The maturest paleoprofiles occur at the northern part of the Catalan Coastal Ranges (i.e. the Montseny-Guilleries High) where the Variscan basement remained exposed during Triassic times. Towards the South the profiles progressively disappear and Triassic sediments acquire their maximum thickness here. The alteration profiles are related with the Permo-Triassic paleosurface still outcroping on wide areas [Gómez-Gras and Ferrer, 1999]. They are partially covered by Triassic fluvial sandstones (Buntsandstein facies) in the South [Gómez-Gras, 1993] and by Palaeocene alluvial conglomerates in the West [Anadón et al., 1979]. The Triassic paleosurface shows a remarkable stability successively outcropping during Mesozoic and Tertiary times, the pre-Tertiary exhumation and even the present day weathering affected very little these albitized profiles. The hardness and thus preservation of the Triassic paleosurface is mainly related to the albitization. The albitized granites are entirely lacking anorthitic plagioclase, which is much more sensitive to chemo-mechanical weathering. Development of albite and additional chloritization of the primary biotite crystals render the rocks much more resistant to weathering and erosion. This stability is particularly well expressed in case of the Montseny-Guilleries High, which is limited by a high fault scarp at the south-eastern margin. The albitized top of the scarp shows remarkably hard fresh rocks, whereas the base of the scarp (formed of primary, non-albitized facies) is deeply weathered into gruss. This is causing much smother landscape reliefs in the valleys and thalwegs. Since a long time the remarkable persistence of the Triassic paleosurface expressed in the Paleozoic massifs has been highlighted by geomorphologists. Only recently we

  6. Spatial and temporal variability of grass cover in two olive grove catchments on contrasting soil types

    Aguilera, Laura; Taguas, Encarnación V.; Gimeno, Enrique; Gómez, José A.

    2013-04-01

    Mediterranean climate conditions -characterized by the concentration of the precipitation in the seasons of autumn and spring, the low temperatures in winter and extremely warm and dry summers- determine that ground cover by adventitious (or cover crop) vegetation shows significant seasonal and annual variability. In addition, its spatial variability associates also, partially, to water availability among the landscape. This is especially relevant in olive orchards, an agricultural system under high erosion risk in the region where the establishment of herbaceous cover has proved to improve soil protection reducing erosion risk, as well as the improvement of soil properties (Gómez et al., 2009). All these benefits are based on small scale studies where full ground cover by the cover crop is relatively easy to obtain. However, few information is available about the actual ground cover achieved at farm scale, although preliminary observations suggests that this might be extremely variable (Gómez and Giráldez, 2009). This study presents the preliminary results evaluating the spatial and temporal evolution of ground cover by adventitious vegetation (the preferred option by farmers to achieve a cover crop) in two commercial olive farms during 2 hydrological years (2011-2012). The study was conducted in two farms located in the province of Cordoba, Southern Spain. Both were olive orchards grown under deficit irrigation systems and present a gauge station where rainfall, runoff and sediment loads have been measured from the year 2005. The soil management in "La Conchuela" farm was based in the use of herbicide in the line of olive trees to keep the bare soil all year round, and the application of selective herbicide in the lane between the olive trees to promote the grown of graminaceae grasses . In addition, the grass is mechanically killed in June. In the another farm, "Arroyo Blanco", the grass spontaneous cover is allowed until mid-spring in which is also

Associated with this primary objective, it was also sought to identify the areas of contact between this forest type and Araucaria forest (mixed ombrophilous forest – MOF. We analyzed data from 78 sample units (AU installed in the remnants of SDF between 2008 and 2009 by professional team of Floristic and Forest Inventory of Santa Catarina project (IFFSC. The data were processed through the Detrended Correspondence Analysis (DCA and Canonical Correspondence Analysis (CCA, using a matrix of species density associated with a environmental variables matrix, that consisted of altitude and climate parameters. The proportion of variance explained by the first three axes of DCA was low, accounting for approximately 21% of the information contained in the original data set. This result provides low power of interpretation of the results. However, when DCA was applied to the data of mean density of species in each river basin, the results pointed to better explanatory eigenvectors (three first eigenvectors explain 58.1% of total variance. The first ordination axis of DCA grouped the eastern watersheds SUs at one end, and the western watersheds SUs at the other end of this axis.

    Restingas are considered stressful habitats associated with the Brazilian Atlantic forest, and their ecological interactions are poorly known. The goal of the present study was to determine the potential role of frugivorous birds as seed dispersers in a restinga habitat. Data were collected in Parque Nacional da Restinga de Jurubatiba, southeastern Brazil, where the main physiognomy (Open Clusia Formation) is characterized by the presence of patches of vegetation covering 20 to 48 % of the sandy soil and reaching a height of 5 m. Birds were captured with mist nets (12 x 2.5 m; 36 mm mesh; 1,680 net-hrs) and had their fecal and regurgitate samples inspected for seeds. Six plant species found in these bird samples were studied. The germination of seeds obtained from plants was compared to those from the birds. Both groups of seeds were set on Petri dishes at room temperature and washed when infected with fungi. In general, there was no effect on germination rate, and the effect on germination speed was negative. Germination of seeds from Pilosocereus arrabidae treated by the birds seemed to be influenced by storage of defecated seeds, while few Miconia cinnamomifolia seeds both from plants and from birds germinated. Ocotea notata presented a great variation in time to the onset of germination, perhaps an advantage against dissecation. Aechmea nudicaulis, Clusia hilariana and Erythroxylum subsessile probably take advantage of the arrival to favorable microhabitats, not by the gut effect on the seeds. All plant species studied are numerically important for the community and some of them are main actors in the succession of vegetation patches. Among the birds, Mimus gilvus is an important resident species, endemic to restingas in Brazil, while Turdus amaurochalinus is a visitor and may be important for plants that fructify during its passage by the study site. Although the effect of pulp removal was only tested for one species (Achmea nudicaulis) in the present study

    Full Text Available Pimenta dioica, allspice, is a neotropical Myrtaceae distributed in Mesoamerica and the Caribbean region. Its área of distribution in México ranges along East and Southeast parts of the country. The main use of its dried fruits is as spice, being sold in Mexican nacional markets as well as exported to Germany, the United States, Jamaica and Great Britain. Most of the harvest comes from trees growing wild in tropical forests, although lately there is a trend to domesticate and cultivate the plant. This paper describes the propagation, domestication, harvesting, processing, marketing and socioeconomic importance of allspice in the Sierra Norte de Puebla (México. The fieldwork has been focused on Totonaca indigenous communities from this area. In these communities, allspice has medicinal use, and is used as a condiment for food; other technological and cultural uses have been also recorded. A historical monograph from Casimiro Gómez Ortega is reviewed. It includes information of the history, botany, cultivation and commerce of allspice.Pimenta dioica es una miliacea neotropical de distribución mesoamericana y caribeña. En México vive hacia el este y sudeste. Sus frutos secos se utilizan como condimento, y se trata de un producto del mercado nacional mexicano que también se exporta a Alemania, Estados Unidos, Jamaica y Reino Unido. Aunque la mayoría de la cosecha proviene de la recolección de los frutos en árboles silvestres del bosque tropical, últimamente se tiende a cultivar esta especie en un proceso actual de domesticación. Se exponen datos sobre propagación, domesticación, cosecha, procesado, mercado e importancia socioeconómica de la pimienta de Jamaica en la Sierra Norte de Puebla (México, a partir de los datos de campo obtenidos principalmente en una comunidad indígena totonaca, en donde se usa como medicinal, en alimentación y en tecnología.

    Background: Exposure to inorganic arsenic (iAs) from drinking water is a global public health problem, yet much remains unknown about the extent of exposure in susceptible populations. Objectives: We aimed to establish the Biomarkers of Exposure to ARsenic (BEAR) prospective pregnancy cohort in Gómez Palacio, Mexico, to better understand the effects of iAs exposure on pregnant women and their children. Methods: Two hundred pregnant women were recruited for this study. Concentrations of iAs in drinking water (DW-iAs) and maternal urinary concentrations of iAs and its monomethylated and dimethylated metabolites (MMAs and DMAs, respectively) were determined. Birth outcomes were analyzed for their relationship to DW-iAs and to the concentrations and proportions of maternal urinary arsenicals. Results: DW-iAs for the study subjects ranged from iAs that exceeded the World Health Organization’s recommended guideline of 10 μg As/L. DW-iAs was significantly associated with the sum of the urinary arsenicals (U-tAs). Maternal urinary concentrations of MMAs were negatively associated with newborn birth weight and gestational age. Maternal urinary concentrations of iAs were associated with lower mean gestational age and newborn length. Conclusions: Biomonitoring results demonstrate that pregnant women in Gómez Palacio are exposed to potentially harmful levels of DW-iAs.
