Joints on the Jos Plateau  

Science.gov (United States)

Supplementary to an earlier study of joint orientations in Nigeria, a detailed study was made of the area around Jos in Plateau State. The results show that throughout this area the joint orientations do not correlate with any of the obvious geological structures (such as ring dykes), but correspond solely to the regional neotectonic stress field.

Genomic and antigenic characterization of Jos virus  

OpenAIRE

Jos virus (JOSV), originally isolated in Jos, Nigeria in 1967, has remained unclassified despite cultivation in tissue culture, development of animal models of infection and implementation of seroprevalence surveys for infection. Here, we report genetic, ultrastructural and serological evidence that JOSV is an orthomyxovirus distinct from but phylogenetically related to viruses of the genus Thogotovirus.

Entrevista con Juan Marichal.  

Directory of Open Access Journals (Sweden)

Full Text Available Juan Marichal nació en Santa Cruz de Tenerife, en 1922, en el seno de una familia ligada al partido republicano insular. Muy joven, en 1935, se trasladó a Madrid, ciudad en la que vive el estallido de la guerra civil. En 1937, pasa a Valencia y luego a Barcelona; tras su exilio en 1938, prosigue sus estudios secundarios en un liceo de París, concluyéndolos en Casablanca. En 1941 emigra a México, formándose en la UNAM: fue alumno de los exiliados José Gaos y Joaquín Xirau así como del mexicano Edmundo O 'Gorman. Luego, becado en Princeton desde 1946, lo fue de América Castro, donde preparó una tesis sobre Feijoo. Apoyado en las vastas perspectivas de sus maestros, fue orientándose hada nuestra historia intelectual, desde el siglo XV hasta hoy. Su carrera profesional se ha desarrollado en los Estados Unidos (coincidiendo con Amado Alonso y con Ferrater Mora: ha sido profesor de estudios hispánicos en la Universidad de Harvard, desde 1948 hasta 1988, año en que se jubiló voluntariamente como numerario (aunque había permanecido en el Bryn Mawr College, entre 1953 y 1957. A este trabajo se suman, con todo, sus conferencias en América Latina y en España. Ha colaborado en las revistas más importantes, en este campo, de México, Nueva York, Puerto Rico, La Habana, Buenos Aires o París así como de las españolas, desde los sesenta. Juan Marichal -hoy, miembro de la Junta Directiva de los Amigos de la Residencia de Estudiantes, director del Boletín de la Institución Libre de Enseñanza y asociado al Instituto Universitario Ortega y Gasset-, reside en España desde otoño de 1989: se considera a sí mismo «voluntario en Madrid», como había dicho Alfonso Reyes en su estancia madrileña (1914-1924.

Un San Juan Bautista firmado por Juan Simón Gutiérrez  

Directory of Open Access Journals (Sweden)

Full Text Available El conocimiento de la pintura sevillana de la segunda mitad del siglo XVII supone uno de los grandes retos de nuestra historiografía artística. Efectivamente, el amplio abanico de discípulos e imitadores del arte de Murillo necesita una profunda revisión metodológica que sepa clarificar la nada fácil tarea de aislar las distintas personalidades que constituyen este importante grupo de artistas. En este sentido la personalidad de Juan Simón Gutiérrez (h. 1634-1724 continua siendo bastante confusa si bien con algunos interrogantes se le van atribuyendo ciertas obras que puedan responder al todavía escaso conocimiento de su estilo frente al amplio grupo de pintores pertenecientes a la escuela de Murillo.

Marketing San Juan Basin gas  

International Nuclear Information System (INIS)

Marketing natural gas produced in the San Juan Basin of New Mexico and Colorado principally involves four gas pipeline companies with significant facilities in the basin. The system capacity, transportation rates, regulatory status, and market access of each of these companies is evaluated. Because of excess gas supplies available to these pipeline companies, producers can expect improved take levels and prices by selling gas directly to end users and utilities as opposed to selling gas to the pipelines for system supply. The complexities of transporting gas today suggest that the services of an independent gas marketing company may be beneficial to smaller producers with gas supplies in the San Juan Basin

Seroprevalence of Canine Brucellosis in Jos, Plateau State, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Serological screening of dogs for brucellosis is not a routine practice in veterinary clinics in Jos. Hence, this study was conducted to determine the prevalence of brucellosis in dogs in Jos North and South Local Government Areas (LGA of Plateau State. A total of 350 sera samples were collected from dogs presented to the clinics. The samples were analysed using Rose Bengal Plate Test (RBPT which gave a prevalence of 113 (32.3%. The RBPT positive samples were then subjected to Competitive Enzyme-linked Immunosorbent Assay (c-ELISA and 33 (29.2% of them were positive. Sero-prevalence increased with age using the c-ELISA as 1 (20.0% of the 5 dogs between 0-6 months, 2 (22.2% of the 9 dogs between 6-11 months and 30 (30.3% of the 99 dogs above 11 months were positive. Based on sex, 6 (28.6% of the 21 male dogs and 27 (29.3% of the 92 female dogs were positive for c-ELISA. Breed-based prevalence recorded 27 (31.0% of 87 exotic breeds, 1 (16.7% of 6 cross-breeds a nd 5 (25.0% of 20 indigenous breeds of dogs assayed. Dogs in Jos South had a higher prevalence of 29 (29.6% of the 98 dogs tested than those in Jos North which had 4 (26.7% of the 15 dogs tested. However, there was no statistical significance between brucella infection and age, sex, breed or location of dogs sampled (p>0.05. This study indicates that canine brucellosis is prevalent in Jos thus, enlightenment and awareness programmes to educate the dog owners should be carried out by the relevant authorities.

¿Hay humor en Juan Montalvo?

Full Text Available Este ensayo analiza la prosa panfletaria de Juan Montalvo desde el punto de vista del humor. Montalvo, además de dedicar muchas páginas a disertar sobre la risa, buscó con frecuencia insertar efectos humorísticos en su estilo, encaminados a ridiculizar a sus enemigos políticos. ¿Hasta qué punto un autor eminentemente moralista, un libelista cáustico como Montalvo, que echa mano del insulto, la burla y el sarcasmo, puede considerarse un humorista? Para comprender esta ambigüedad entre un Montalvo solemne y otro burlón, entre un Montalvo austero y otro irónico se analizan aquí ciertos recursos literarios que utiliza este autor y con los que provoca efectos que lindan con lo humorístico.This work analyses Juan Montalvo's pamphlet prose from a humorous perspective. To what extent can an eminently caustic moralist author as Montalvo, who uses insult, mockery and sarcasm, be considered a humorist?

Fray Juan Rizi en Italia  

Directory of Open Access Journals (Sweden)

Full Text Available Since Tormo, Gusi and Lafuente wrote fray Juan Rizi's monograph in 1930, and Ángulo & Pérez Sánchez revised years later this study in their book Pintura madrileña del segundo tercio del siglo XVII, very little has been published about the life and work of the Benedictine painter. Furthermore, the Italian journey of Rizi, that involved the last 20 years of his life, has always been an enigma, resolved only in certain aspects, thanks to few news supplied by his biographers and the manuscripts the monk wrote during his staying in the Montecassino abbey. Our recent discovery of 8 new canvases painted by Rizi to decorate the Saints Cosme and Damian's chapel in the main church of Trevi nel Lazio (Frosinone, Italy, as well as the location of several new drawings in the Montecassino and Vatican libraries, will allow us to study his activity as painter in Italy and also to profile, with more accuracy, the history of the last years of his life.No disponible

Isolation and molecular characterization of Candida africana from Jos, Nigeria.  

Science.gov (United States)

During a survey of the prevalence of Candida spp. in Jos, Plateau State, Nigeria, two atypical C. albicans isolates were recovered. These two yeasts were germ tube positive, chlamydospore-negative and gave a green color on CHROMagar Candida. Molecular analysis performed by amplification of the hwp1 gene showed that these two isolates belonged to C. africana, a newly proposed Candida species closely related to C. albicans. Based on the presence or absence of an intron in DNA sequences encoding rRNA, the two C. africana, including all C. albicans isolates examined, were found to belong to genotype A and no other genotypes or species such as C. dubliniensis were found. To our knowledge, this is the first isolation of C. africana in Nigeria. PMID:22380533

Histopathologic diagnoses of lymphadenopathy in children in Jos, Nigeria.  

Science.gov (United States)

Histopatholgical findings in 242 lymph node biopsies received in Jos University Teaching Hospital over a 10-year period (1988-1997) were reviewed. Tuberculosis is the most predominant lesion (33.05%), followed closely by the non-Hodgkin's lymphoma (31.4%). Burkitt's lymphoma accounting for one-quarter of all the cases of non-Hodgkin's lymphoma had a peak age range of 8-10 years. Hodgkin's lymphoma, chronic non-specific lymphadenitis, sinus histiocytosis, reactive hyperplasia, metastatic carcinoma, dermatopathic lymphadenitis, Kaposis sarcoma and sarcoidosis accounted for 2.9%, 14.46%, 9.9%, 4.96%, 1.7%, 0.4%, 0.8% and 0.4% respectively. The cervical region was the commonest site affected (54.1%), followed by mesenteric (22.3%), axillary (13.2%) and inguinal (10.3%). BCG immunization was carried out only on 121(50%) of cases, out of which 60 had tuberculosis and 54(22.3%) received no BCG immunization, while 67(27.7%) had no records of BCG immunization. Only 5(2%) had HIV screening done, out of which one was positive. PMID:14692059

Juan Preciado: viaje, ilusión y esperanza Juan Preciado: Journey, Illusion, and Hope  

Directory of Open Access Journals (Sweden)

Full Text Available Pedro Páramo es quizás uno de los textos que más ha influido en las letras hispanoamericanas. Muchos son los estudios que se han realizado a esta obra, algunos de ellos insisten en el tono pesimista de la misma. La novela inicia con un viaje, el del hijo que sale en busca de su padre para cumplir la promesa hecha a la madre en el lecho de muerte. Esta ha sido la interpretación más difundida por la crítica. Sin embargo, si se lee detenidamente el discurso del protagonista se cae en la cuenta de que no es ése el motivo principal de su viaje a Comala. En realidad, Juan Preciado es movido por la esperanza que era "aquel señor" llamado Pedro Páramo, no por la promesa hecha a Dolores, de la que él mismo dice que no pensaba cumplir hasta que comenzó a llenarse de sueños, de ilusiones y de esperanza. El viaje de Juan va de la esperanza a la ilusión para terminar en la muerte. La acción se arraiga en ese sentimiento que mueve a todo ser humano y se convierte así en una extensa metáfora del sentido (o sin sentido de la vida. Este escrito reflexiona sobre la presencia de la esperanza y de la ilusión en la novela de Juan Rulfo.Pedro Paramo is perhaps one of the literary texts that has had the greatest influence on Spanish American letters. Many studies have been done related to this work, and some of them insist on its pessimistic tone. The novel begins with the journey of a son who sets out to look for his father in order to fulfill the promise made to his mother as she lay dying. This has been the most widely diffused interpretation given by critics. Nevertheless, if one reads carefully the discourse of the protagonist, one comes to understand the principle motive for his journey to Comala. In reality, Juan Preciado is motivated by the hope that it was "that man" named Pedro Paramo that prompted the journey, not the promise made to Dolores, something that he himself says that he was not planning to fulfill until he started to be filled with dreams, illusions, and hope. Juan's journey goes from hope to illusion, culminating in death. The action is rooted in that sentiment that moves every human being and thus changes in an extensive metaphor for the meaning (or without meaning of life. This manuscript reflects on the presence of hope and illusion in the novel of Juan Rulfo.

JosD1, a membrane-targeted deubiquitinating enzyme, is activated by ubiquitination and regulates membrane dynamics, cell motility, and endocytosis.  

Science.gov (United States)

The functional diversity of deubiquitinating enzymes (DUBs) is not well understood. The MJD family of DUBs consists of four cysteine proteases that share a catalytic "Josephin" domain. The family is named after the DUB ATXN3, which causes the neurodegenerative disease Machado-Joseph disease. The two closely related Josephin domain-containing (JosD) proteins 1 and 2 consist of little more than the Josephin domain. To gain insight into the properties of Josephin domains, we investigated JosD1 and JosD2. JosD1 and JosD2 were found to differ fundamentally in many respects. In vitro, only JosD2 can cleave ubiquitin chains. In contrast, JosD1 cleaves ubiquitin chains only after it is monoubiquitinated, a form of posttranslational-dependent regulation shared with ATXN3. A significant fraction of JosD1 is monoubiquitinated in diverse mouse tissues. In cell-based studies, JosD2 localizes to the cytoplasm whereas JosD1 preferentially localizes to the plasma membrane, particularly when ubiquitinated. The membrane occupancy by JosD1 suggests that it could participate in membrane-dependent events such as cell motility and endocytosis. Indeed, time-lapse imaging revealed that JosD1 enhances membrane dynamics and cell motility. JosD1 also influences endocytosis in cultured cells by increasing the uptake of endocytic markers of macropinocytosis while decreasing those for clathrin- and caveolae-mediated endocytosis. Our results establish that two closely related DUBs differ markedly in activity and function and that JosD1, a membrane-associated DUB whose activity is regulated by ubiquitination, helps regulate membrane dynamics, cell motility, and endocytosis.

Full Text Available Al Occidente de Cundinamarca, hay un gran Sinclinal de dirección Norte-Sur cuya estratigrafía es completamente diferente a la del centro y Oriente de dicho departamento. El Cretáceo de dicha estructura, presenta características similares a las de la Formación Yaví descrita en el Sur del Tolima y el Hulla.  En san Juan de Ríoseco parece presentarse un Paleoalto, con sedimentación continental, ilimitado por grandes fallas de rumbo al Este y oeste de la estructura mencionada. In the Western part of Cundlnamarca there is a large North-South synclinal structure with a completely different stratigraphy than that of the Central and Eastern portions of Cundinamarca.  The Cretaceous of this structure has characteristics similar to those of the Yaví Formation of Southern Tolima and Huila.  There seems to be a paleo-high in San Juan de Ríoseco, with continental sedimentation, limited by great faults on both the Eastern and Western extremes of the structure.

Model Simulations of Waves in Hurricane Juan  

Science.gov (United States)

Hurricane Juan made landfall at 0300 UTC near Halifax Nova Scotia. This was a category 2 hurricane with winds of 44 m/s, the largest storm to pass over these coastal areas in several decades. Associated high ocean waves were experienced in coastal waters, from Peggy's Cove to Sheet Harbour, growing to epic proportions on the Scotian Shelf, and exceeding the 100-year return wave based on the present climatology. As part of the GoMOOS program (Gulf of Maine Ocean Observing System, www.gomoos.org), winds from the USA Navy COAMPS (Coupled Ocean Atmosphere Model Prediction System) were used to evaluate and compare three widely-used third generation numerical wave models, SWAN, WAM and WaveWatch-III (hereafter WW3) for accuracy, with in situ measurements. Model comparisons consist of a set of composite model systems, respectively nesting WAM, WW3 and SWAN in WAM and WW3. We report results from the intermediate-resolution grid for Hurricane Juan. Wave measurements were made using four operational deep-water buoys (C44258, C44142, C44137, 44005), by a conventional directional wave rider (DWR) moored offshore from Lunenburg Bay, and also by two acoustic Doppler current profiler (ADCP) located (1) near an oil rig on Sable Island Bank, in relatively shallow water, and (2) near the outer boundary of Lunenburg Bay. We discuss the reliability of DWR wave data compared to ADCP wave data. We show that all models provide reliable hindcasts for significant wave height (Hs) and for peak period (Tp) for Juan, although a clear under-estimation of Hs at the peak of the storm is evident, compared to observations. A feature in the COAMPS storm simulation is that the storm track appears to be slightly to the east of that of Quikscat scatterometer data. Comparisons between models and 2-dimensional wave spectra are presented. Preliminary results suggest that the recently released upgrade to the WW3 model shows slightly enhanced skill compared to the other models.

Depression among medical outpatients with diabetes: A cross-sectional study at Jos University Teaching Hospital, Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Clinical depression is a common problem among patients who seek medical care, and diabetic patients with comorbid depression tend to have higher health care cost. A dearth of literature exists on depression among diabetics in Nigeria. The objectives of the study were to determine the prevalence of depression among diabetic patients and to determine the sociodemographic correlates of depression among diabetics. Methods: A cross-sectional descriptive study was conducted between December 2005 and April 2006 among patients who attend the diabetes clinic of Jos University Teaching Hospital (JUTH with a laboratory and clinical evidence of diabetes mellitus. A semi-structured questionnaire was used to record the sociodemographic data of each consecutive patient followed by an interview by psychiatrists using the depression module of the Structured Clinical Interview for DSM-I V axis I disorder (SCID. Subsequently, the Hamilton Rating Scale for Depression (HDRS was used to determine the severity of symptoms among subjects diagnosed with depression according to DSM-I V criteria. Results: Thirty-one of the 160 subjects fulfilled the DSM-IV criteria for the diagnosis of a major depressive episode giving a 1-year prevalence rate of 19.4%. Depression was significantly correlated with sex (P=0.001 with a female-to-male ratio of 3:1 and was also significantly associated with unmarried diabetics (P=0.002 and those who had a poor relationship with their partners (P=0.04. No significant association was found between depression and the respondents? age (P=0.216, educational qualifications (P=0.268, employment status (P=0.84, place of residence (P=0.80, household composition (P=0.77, and monthly income (P=0.110. Conclusion: Depression is a common psychiatric disorder among diabetic subjects in this environment. It was suggested that diabetic patients be screened for depression to allow for early detection and treatment.

Su obra ha sido estudiada por diferentes autores, intentando explicar su filiación con modelos caravaggiescos en fechas tan tempranas, y sobre todo su modernidad, pues anticipa en el Madrid de los primeros decenios del XVII una manera de entender el arte completamente nueva. Precisamente en su producción el gusto por la sensualidad y la desnudez no pasa inadvertida en sus modelos y este aspecto también presente en la pintura de Anibale Carracci y Guido Reni, no permaneció ajeno en la historiografía artística, pues el propio Jusepe Martínez cuenta que Maíno era discípulo de Carracci y compañero de Guido Reni.

Roller-bearing tectonic evolution of the Juan Fernandez microplate  

Science.gov (United States)

A combined GLORIA sidescan and Hydrosweep multi-narrow-beam sonar survey shows striking evidence for fan-shaped spreading systems, bounding pseudofaults and compression ridges associated with 90° of clockwise rotation of the Juan Fernandez microplate in the past 4 Myr. A quantitative analysis of this evolution suggests that the microplate has rotated as a rigid 'roller bearing' for most of its history, driven at its edges by shear between the surrounding major plates. The remarkable similarity between the Juan Fernandez and Easter microplates, despite their different tectonic settings, suggests that this is a general model for microplate tectonics.

Umbrales: La escritura cinemática de Juan Emar / The Cinematic Writing of Juan Emar  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish Este trabajo desarrollará la idea de que la escritura crítica, metaficcional y autorreferente de Juan Emar -desde las "Notas de Arte" (1924-1927) hasta el proyecto monumental de Umbral (1940-1964)- puede comprenderse, por un lado, como espacio de resonancia de una estructura cinemática de percepción [...] que se perfila como fundamental experiencia de vida durante la primera mitad del siglo XX. Por otro lado, sus textos, en diferentes niveles enunciativos, son parte de la conceptualización de esta misma experiencia. En este sentido, lo cinemático es un imaginario multiforme de la percepción del movimiento que culmina en el cine de vanguardia de los años veinte; mientras que lo cinematográfico se relaciona con el fenómeno del cine propiamente tal, sus posibilidades tecnológicas y los elementos que lo convierten en espectáculo. Estos polos tensionan la escritura de Emar en el nivel referencial, reflexivo, y estético-formal. Abstract in english This article will develop the notion that the critical, metafictional and self-referential writings of Chilean author Juan Emar - from his "Notas de arte" (1924-1927) to his monumental project Umbral (1940-1964) - can be understood as a space for the resonance of a cinematic structure of perception [...] that emerged as an essential experience during the first half of the 20th century. On the other hand, his texts, in diverse levels of enunciation, are part of the conceptualization of the same experience. In this sense, the cinematic is a polymorphic imaginary of movement perception which culminates in the avant-garde cinema of the 1920s; whereas the cinematographic is related more strictly to the phenomenon of cinema, the technological possibilities and the elements that transform it into spectacle. These poles create tension on various levels of Emarís writing: the referential, the reflexive, the formal-esthetic.

The green areas of San Juan, Puerto Rico  

Directory of Open Access Journals (Sweden)

Full Text Available Green areas, also known as green infrastructure or urban vegetation, are vital to urbanites for their critical roles in mitigating urban heat island effects and climate change and for their provision of multiple ecosystem services and aesthetics. Here, I provide a high spatial resolution snapshot of the green cover distribution of the city of San Juan, Puerto Rico, by incorporating the use of morphological spatial pattern analysis (MSPA as a tool to describe the spatial pattern and connectivity of the city’s urban green areas. Analysis of a previously developed IKONOS 4-m spatial resolution classification of the city of San Juan from 2002 revealed a larger area of vegetation (green areas or green infrastructure than previously estimated by moderate spatial resolution imagery. The city as a whole had approximately 42% green cover and 55% impervious surfaces. Although the city appeared greener in its southern upland sector compared to the northern coastal section, where most built-up urban areas occurred (66% impervious surfaces, northern San Juan had 677 ha more green area cover dispersed across the city than the southern component. MSPA revealed that most forest cover occurred as edges and cores, and green areas were most commonly forest cores, with larger predominance in the southern sector of the municipality. In dense, built-up, urban land, most of the green areas occurred in private yards as islets. When compared to other cities across the United States, San Juan was most similar in green cover features to Boston, Massachusetts, and Miami, Florida. Per capita green space for San Juan (122.2 m²/inhabitant was also comparable to these two U.S. cities. This study explores the intra-urban vegetation variation in the city of San Juan, which is generally overlooked by moderate spatial resolution classifications in Puerto Rico. It serves as a starting point for green infrastructure mapping and landscape pattern analysis of the urban green spaces within the city of San Juan. The effectiveness of research and city planning will be further enhanced as a result of this type of finer-scale urban cover exploration.

Factors associated with antiretroviral treatment interruption in human immunodeficiency virus (HIV)-1-infected children attending the Jos University Teaching Hospital, Jos, Nigeria  

Science.gov (United States)

Background: Interrupting anti-retroviral therapy (ART) for any number of reasons is an indication of a compromised adherence to ART. Several factors, including the pill burden from other drugs used in treating co-infections in children with human immunodeficiency virus (HIV), may influence ART adherence. The aim of this study was to identify the factors associated with ART interruption in HIV-1-infected children. Materials and Methods: A retrospective cohort study analysing data on 580 children consecutively enrolled on ART between February 2006 and December 2010 at the paediatric HIV clinic of Jos University Teaching Hospital (JUTH), Jos. Subjects were children aged 2 months — 15 years diagnosed with HIV-1 infection and on first-line ART. Cotrimoxazole prophylaxis was usually commenced at diagnosis while awaiting ART commencement. Children diagnosed with tuberculosis (TB) were also placed on multiple individual anti-TB drugs. Statistical analysis used: A comparison of the data on children with and without ART interruption was made. Variables associated with ART interruption in a univariate analysis were fit in a multivariate logistic model to determine the factors that were associated with ART interruption. Results: Children on anti-TB drugs were twice more likely to interrupt ART compared to those who were not, (adjusted odds ratio, AOR = 1.84 (1.03-3.28); P = 0.04). But children on cotrimoxazole prophylaxis had a 57% reduction in the odds of interrupting ART compared to those who were not, (AOR = 0.43 (0.20-0.93); P = 0.03). Conclusion: Children on ART and also taking multiple individual anti-TB drugs should be monitored closely for ART adherence. Cotrimoxazole prophylaxis should be encouraged in children diagnosed with HIV while awaiting ART commencement as this may prime them for a better ART adherence. PMID:25657493

Los relatos policiales de Víctor Juan Guillot / Victor Juan Guillot’s Detective Stories  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish Los relatos policiales de Víctor Juan Guillot han sido hasta aquí completamente ignorados por la crítica literaria y la historiografía del género policial en la Argentina. Sostenemos que en estos relatos de Guillot puede advertirse el pasaje desde un modelo de relato policial -aquel que sería el fun [...] damental desde fines de la década de 1870 hasta aproximadamente 1930, con claros aspectos folletinescos y vínculos estrechos con la realidad política y social- hacia una narración detectivesca más cercana al modelo de la Edad de Oro del policial en lengua inglesa y más alejado de la vida empírica nacional. Este último tipo de policial se desarrollará con vigor durante las décadas de 1930 y 1940. En este sentido, mostramos en qué medida los relatos policiales de los libros Historias sin importancia (1920) y El alma en el pozo (1925) consuenan con la tradición temprana del género en la Argentina, mientras que los cuentos incluidos en Terror: cuentos rojos y negros (circa 1935) se hallan en sintonía con los policiales de la década de 1930. Asimismo, exhibimos de qué manera las concepciones de Guillot -expresadas en la poética de sus relatos y también en reflexiones sobre la novela policial- anticipan ya desde 1925 las ideas de Jorge Luis Borges sobre lo policial durante los años 30. Abstract in english This paper studies Victor Juan Guillot’s detective stories, hitherto, completely ignored by the literary criticism and the historiography of the detective genre in Argentina. We assert that in these stories it is possible to see the transition from a certain detective narrative -which was clearly pr [...] edominant from late 1870s to 1930s, having melodramatic features and close links with the political and social reality- into a new kind of tale much closer to the English detective story of the Golden Age, and further from empirical national life. In Argentina, this new type of detective tale will be developed vigorously during the 1930s and the 1940s. Thus, we attempt to show that the detective stories included in Historias sin importancia (1920) and El alma en el pozo (1925) are in the same line with the early tradition of the genre in Argentina, while the stories included in Terror: cuentos de crimen y misterio (circa 1935) have mostly the same features as those of the 1930s. We also seek to put on view how Guillot’s conception of the detective story in 1925 anticipated Jorge Luis Borges’s conception of the genre in the 30s.

Implication of Intangible Location Attributes on Residential Segregation in Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Residential segregation could be regarded as a process whereby two or more distinct communities who formerly lived together separate from one another due to many factors. Residential segregation is not only applicable to small communities but rather to a larger region. As a result of the ongoing civil unrest that engulfed the city of Jos, there has been a process of residential mobility and relocation among people of different faith. The paper is aimed at examining the implication of intangible location attributes on residential mobility, segregation and relocation in Jos town. Stratified random sampling technique was employed in order to come up with the sample needed to conduct the research. The data needed for the research were retrieved through structured, semi-structured and unstructured interview method of data collection. A qualitative method and approach of data analysis through the use of a thematic network analysis was incorporated in order to analyse the data gotten from the interview survey. The results uncovered that residential segregation in the study area leads to change in the residential pattern of Jos town. The variations and trends in the sales and rental value of residential properties were greatly affected as a result of the persisting residential segregation. The research concludes that residential segregation has a great implication on land and landed property value as variations in the values of residential properties is noticeable. There is a need for those in authority to take a decisive action in order to overcome and halt the persisting mobility and relocation in the study area.

Radiological measurement of some nuclides in processed mine tailings in Jos  

International Nuclear Information System (INIS)

The Jos plateau is situated in the central part of northern Nigeria; on a rugged terrain of low lands at the edge of the plateau surface. It is the principal centre of tin and columbite mineralization, which forms the focal area of younger granites. The mine tailings are associated with radioactive minerals as impurities such as monazite, zircon among others. These minerals are very radioactive and cause hazards to human health during mining and milling. A total of thirty-one tailings (31) samples from a mining and processing site in Jos were collected at different directions and distance and analyzed for ''4''0K, ''2''2''6Ra and ''2''3''2Th concentrations using NaI(TI) detector, in order to estimate the level of their radiological impact to the public. Samples D8 of ''2''3''2Th, B2 of ''2''2''6Ra D8 of ''4''0K show high concentrations in the composite tailings. D6 of ''2''3''2Th, D5 of ''2''2''6Ra and C7 of ''4''0K show low concentrations in the composite tailings. The highest and lowest concentrations are in D8 of ''2''3''2Th (27930.0 Bq/kg) and D5 of ''2''2''6Ra (364.9 Bq/kg). All concentrations range from (364.9 Bq/kg - 27930.0 Bq/kg) in the tailings. Considering ''2''2''6Ra, ''4''0K and ''2''3''2Th concentrations, it could be said that the major source of radiation in Jos, Plateau State is thorite

Chemical Water Quality Assessment in Selected Location in Jos, Plateau State, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available The study examined well water quality (chemical in Jos metropolis which it collected a total of twenty water samples that were taken for laboratory analysis. The stratified systematic random method was used in the selection of sample area/location. A total of (10 out of the existing (20 wards were systematically selected, while in each of the wards, two wells with one each from higher and lower elevations were randomly selected in which water samples were collected. The samples collected were analyses at UNICEF (WATSAN Laboratory Bauchi. USEPA method of water analysis was used to test for the chemical parameters. Pearson product moment correlation co-efficient was used test for the relationship between high and low elevation in the sample elements, as well as mean and standard deviation. The results indicates that pH, E.C, TDS, Pb, As and Cyanide appears within NSDWQMPL, while NO2, Cl, F, Mn, Mg, Ca, Cu, Zn, CaCo3 and Cr marginally falls within acceptable standard for drinking water quality maximum permitted limit. Consequently, NO3, SO4, Fe and CaCo3 in some parts of Jos metropolis fall outside acceptable standard of NSDWQMPL. Moreover, pH, E.C, TDS, Pb, NO2, NO3, Cl, F, Mn, Cr, As, Cu, Zn, showed that there is no significant relationship within the individual elements in regards to elevation (high and low in the study area whereas, SO4, Fe, Mg, Ca, CaCo 3 and CaCo3 showed that there is significant relationship in elevation (high and low among the individual sample elements. The study concludes that well water quality through chemical assessment in Jos metropolis is not fit for drinking.

Aquifer transmissivity and basement structure determination using resistivity sounding at Jos Plateau State Nigeria.  

Science.gov (United States)

A geoelectric investigation involving twenty-six vertical electrical soundings was carried out at Jos, Plateau State, North Central Nigeria. The survey was aimed at determining the structure of the underlying bedrock, as well as computing the transmissivity for the aquifer in the area. The basement geometrymapproduced from the results of the survey indicates that the bedrock is undulating lying at depths between 30 m to 6.5 m. There is evidence of faulting and fracturing within the area. Computation of aquifer transmissivity values based on the results obtained made it possible to demarcate regions with good ground water potential in the area. PMID:16570227

Serological Survey Of Salmonella gallinarum Antibody In Chickens Around Jos, Plateau State, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available A serological survey of the prevalence of antibodies to Salmonella gallinarum among chickens under two different management systems around Jos, Plateau State, Nigeria was carried out using the standard plate agglutination test. The objective of this study was to determine serologically the prevalence of antibodies against Salmonella gallinarum among apparently healthy chickens around Jos. A total of 700 serum samples made up of 450 exotic and 250 local breed of chickens were used for this study with 37.9% seropositvity. In the free range system (19.3% of the flocks sampled were seropositive for Salmonella gallinarium antibodies while in the semi intensive, 18.6% of the flock tested positive. The serum agglutination test (SAT was adapted to the microtitre format used to determine somatic and flagella titres. The antigen used for this study was specific for S. gallinarum, hence differentiation between species infection was assessed in this study. Perhaps the most feasible way to eradicate the disease is to encourage farmers (both small and large scale to break the disease cycle at their levels by embarking on prompt and regular vaccination programmes. It is thus concluded that Salmonella gallinarum (fowl typhoid is present in the area investigated. Fowl typhoid may continue to have a negative effect on the economy of poultry production in Nigeria if not controlled. A statistical analysis was precluded due to inadequate data sets.

Knowledge and attitude of secondary school students in Jos, Nigeria on sickle cell disease  

Science.gov (United States)

Introduction Knowledge about sickle cell disease among youths could constitute an important variable that influences their premarital attitude and behaviour. The study is to determine the knowledge and attitude on Sickle Cell Disease among selected secondary school students in Jos metropolis, Nigeria. Methods A cross sectional descriptive study involving 137 Secondary School Students within Jos metropolis selected by a multistage stratified sampling technique, using self administered structured questionnaire. Data were analyzed using SPSS version 17. Results A total of 137 students were interviewed, Christians 88%, modal age range 15-20 years (72%) and males (51%). Majority (83.2%) of the respondents were aware of SCDs, as an inherited disorder (80.0%), affecting the red blood cells (83.0%) but only half (54%) knew that the disease can only be diagnosed through blood test. Also, only 59% knew their genotype and 11. 1% claimed AS genotype. More than one fourth (25.5%) had wrong belief that SCD is caused by evil spirit while 76% showed wrong attitude involving stigmatization towards individuals with sickle cell disease. Conclusion Comprehensive knowledge about SCD was found to be low despite good awareness among respondents, but only few knew their haemoglobin genotype. If sickle cell disease control strategies must yield any significant results, there is a need to raise awareness about SCD, especially among students in secondary institutions in Nigeria is recommended.

Aetiological significance of alcohol in liver cirrhosis on the Jos Plateau.  

Science.gov (United States)

Fifty-one patients with histologically diagnosed cirrhosis were studied prospectively over one year period. There were forty-one males and ten females. The majority of patients (75.59%) took alcohol in significant quantity and it was thought to be the most likely cause of the cirrhosis in them. Eighty percent of them had micronodular cirrhosis and 51.3% of them drank only "burukutu" a local alcoholic brew brewed mostly in iron pots and contains two other hepatotoxic agents--aflatoxin and iron. Eight (5.7%) of the patients and five (9.8%) of controls were positive for hepatitis B surface antigen (HBs.Ag). It is likely that alcohol is very important cause of cirrhosis of the liver seen in Jos. PMID:12081334

Profile of clients requesting for removal of intrauterine devices in Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Background : Intrauterine contraceptive devices are commonly used reversible methods of contraception in Jos, Nigeria. There is dearth of information on the effect of the IUD on client weight during the period of use. It is expected that the increased bleeding disorder associated with the intrauterine device may predispose to anaemia and some degree of weight loss. Method :A retrospective study of all patients having their previously inserted IUDs removed at the Jos University Teaching Hospital, Northern Nigeria, between January 1999 and December 2004. Results : The mean (± SD age and parity of the clients was 32.9 ± 6.9 years and 4.0 ± 2.2 respectively. All the women were married and none of them was a nullipara. The TCu-380A IUD was used in 99.3% of the cases. The women were using the method for a mean of 51.5 ± 51.0 months or 4.3 years, and the commonest indication for removal was the desire for another pregnancy in 30.7% of the clients, followed by back pain in 12.6%. The mean weight (± SD of the women at the insertion of the IUD was 66.67 ± 13.95 kg and the mean weight at the removal of the device was 69.3 ± 14.9 kg. The average weight gain with IUD use was therefore 2.6 kg. Conclusion : The observed weight increase in IUD users is probably occasioned by the annulment of the fear of pregnancy, and the tendency of women to gain weight with increasing age.

The 5.5 mile-long segment of a seismic line illustrated in the report is part of a seismic survey near Crownpoint, New Mexico. It may be used as a reference line for future uranium-related seismic studies, as it crosses two uranium orebodies and is in an area that has been extensively drilled and studied. It also demonstrates the seismic character of the uranium-bearing Upper Jurassic Morrison Formation in the southern San Juan Basin. Seismic techniques may be used to locate the drilling targets and thus provide a more efficient means for uranium exploration.

Methods and materials: Individuals who were confirmed healthy and not on any form of medication were enrolled in the study after the administration of a questionnaire which ruled out any form of aliment such as fever, gastroenteritis, and malaria. The serum glucose level was quantified using the glucose oxidase reagent. Data generated were analyzed using Excel 2007 (Microsoft®, Redmond, WA and Student’s t-test for an established normal range. Results: The age distribution showed that those aged 14–16 years had a mean serum glucose level of 4.8 ± 1.11 mmol/L, while in those aged 17–19 years it was 4.9 ± 1.115 mmol/L, with a standard error of the mean of 0.17 and 0.15, respectively. The mean glucose level, weight, and height of the enrollees were 4.8 ± 1.12 mmol/L, 56.6 ± 6.20 kg, and 1.6 ± 0.009 m, respectively. The mean serum glucose of those from the Berom tribe and other tribes was 4.9 ± 1.21 mmol/L and 4.8 ± 1.15 mmol/L, respectively. Analysis of the mean glucose level with respect to sex, age, tribe, weight, and height of the established normal mean resulted in a P value of < 0.05, which was not significant. Conclusion: There was no significant difference in the serum glucose level of enrolled subjects. It was also observed that there was no significant difference between the glucose level based on the different tribes, sex, weight, and height of all enrolled subjects. Since glucose is involved with various body metabolic processes and is also an analyte of interest in diabetes mellitus, screening of adolescents would reduce the incidence of the disease. Keywords: Blood glucose, adolescents, diabetes mellitus

Characterizing Dynamic Bedforms Using Multibeam Bathymetry in the Haro Strait and San Juan Channel Areas of British Columbia, Canada, and the San Juan Islands, Washington, USA  

Science.gov (United States)

The San Juan Islands in the U.S. and British Columbia, Canada, are an archipelago located in Northwestern Washington, between the Northern Cascades Mountain Range and the Olympic Peninsula and are the result of tectonic compressional processes. This region has experienced a complex tectonic history of convergence, thrust faulting, uplift, subsidence, glaciation, tidal scour and sediment transport (deposition and erosion) that in turn have produced diverse marine benthic habitats. There are a variety of habitats including dynamic bedforms, moraines, and glacially scoured fractured and faulted bedrock outcrops. Multibeam bathymetric and backscatter data image the bedforms in detail and show they are concentrated within the waterways of the San Juan Islands, including Haro Strait, the Strait of Juan de Fuca and San Juan Channel. These bedforms may provide habitat for marine species, including migrating salmon. An interpreted map will be presented that focuses on the characterization of marine benthic habitats based on high-resolution (Simrad EM 1002 95 kHz) multibeam bathymetry and backscatter data. This study will assist in a better understanding of the physical and biological characteristics of the San Juan Islands Archipelago, especially near established Marine Protected Areas and will benefit effective implementation of resource management objectives.

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Sero-survey of rubella IgM antibodies was carried out among children aged 0-10 years in Jos, Nigeria. Blood samples were collected from the subjects and sera extracted. Of the 93(100% assayed for the rubella IgM antibody, 42(45.2% were seropositive for rubella IgM antibody while 51(54.8% were seronegative. A breakdown of the seropositive subjects reveals that 14(15.1% of the infected children were males while 28(30.1% were females. Those subjects within the age groups of 1-2, 3-4 and 5-6 years had the highest prevalence of 8(8.6% followed by those within the age groups of 7-8, 9-10 years with 7(7.5%. Blood transfusion as a risk factor did not show any significant influence on the status of the subjects. The demographic data of the mothers of the subjects were also linked with the seropositivity of the children.

Incidence of rotavirus infection in children with gastroenteritis attending Jos university teaching hospital, Nigeria.  

Science.gov (United States)

This study was conducted to determine the incidence of rotavirus infection in children with gastroenteritis attending Jos university teaching hospital, Plateau State. A total of 160 children with acute diarrhea were selected by random sampling. Stool samples were obtained and assayed for rotavirus antigens by enzyme linked immunosorbent assay technique using standard diagnostic BIOLINE Rotavirus kit. Demographic data of parents were also recorded. Rotavirus were detected in faeces of 22(13.8%) children with acute diarrhea, 90.9% of positive cases of rotavirus gastroenteritis were under 2 years of age with highest prevalence in children 7-12 months of age. Males excreted rotavirus at a significant higher rate than females (P<0.05). Rotavirus excretion was highest when all three symptoms (diarrhea, fever and vomiting) occurred in the same child (7.5%) and lower when 2 symptoms occurred together (diarrhea and vomiting) with 3.8%, diarrhea and fever with 1.3% and lowest when diarrhea occurred alone with 1.3%. Playing with toys, attending day care, distance of source of water from toilet, eating of food not requiring cooking and playing with other children may serve as predisposing factors of rotavirus disease in these children.

Flagellar mitochondrial association of the male-specific Don Juan protein in Drosophila spermatozoa.  

Science.gov (United States)

The Drosophila don juan gene encodes a basic protein (Don Juan protein), which is solely expressed postmeiotically during spermiogenesis in elongated spermatids and in mature sperm. Transgenic expression of a GFP-tagged Don Juan protein (DJ-GFP) in the male germ line showed an association of the fusion protein with the sperm tail. Detailed examination of DJ-GFP localization revealed novel insights into its distinct temporal and spatial distribution along the sperm tail during the last phase of spermatid maturation. Co-localization of DJ-GFP with actin-labeled cysts demonstrated its emergence in elongated spermatids during individualization. Additionally, the endogenous Don Juan protein was detected with epitope-specific antibodies in finally elongated nuclei of spermatids. After completion of nuclear shaping Don Juan is no longer detectable in the sperm heads with the onset of individualization. Mislocalization of the DJ-GFP protein in flagella of a mutant with defective mitochondrial differentiation provides evidence of mitochondrial association of the fusion protein with flagellar mitochondrial arrays. Ectopically expressed DJ-GFP in premeiotic germ cells as well as salivary gland cells confirmed the capability of the fusion protein to associate with mitochondria. Therefore we suppose that Don Juan is a nuclear-encoded, germ-cell specifically expressed mitochondrial protein, which might be involved in the final steps of mitochondrial differentiation within the flagellum.

Siendo el material abundante, en esta primera parte se presentan y examinan los textos relacionados a la parte narrativa (Jn 6,1-21), y se inician a presentar los textos relacionados al discurso de Jesús (Jn 6,35-59). En efecto, está claro que el interés de Orígenes se ha dirigido particularmente al discurso en el que Jesús se declara "pan de la vida". Aquí se verán los textos contenidos en el De Oratione, en el Comentario a Juan, y en el Comentario a Mateo. En la segunda parte del estudio se terminará de presentar los textos relacionados al tema del "pan de la vida" y que están contenidos en las Homilías al Génesis, Homilías al Éxodo, Homilías al Levítico, Homilías a los Números y Homilías a Josué.

Given that the material is abundant, this first part presents and examines only the texts related to the narrative part (Jn 6, 1-21) and starts introducing the texts related to Jesus' words (Jn 6, 35-59). In fact, it clear that Origen's interest focuses particularly on Jesus' speech in which He calls himself "bread of life". This paper presents the texts comprised in De Oratione, Comment on John, and Comment on Mathew. The second part of this study presents the remaining texts related to the "bread of life" speech, which are contained in the Homilies on the Genesis, Homilies on Exodus; Homilies on Leviticus, Homilies on Numbers and Homilies on Joshua. The author also makes a balance of the presence of this issue in the other works by Origen which have to come to our days, to end up emphasising the train of thought of Origen's exegesis about Jn 6

Full Text Available Antibacterial activity of ethanolic extract of Acalypha wilkesiana leaves growing in Vom, Jos, Plateau state, Nigeria was carried out to verify claims by the locals of its medicinal properties. We tested the extract for activity against Staphylococcus aureus (G+, Yersinia enterocolitica, Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa and Klebsiella aerogenes (G-. The extract exhibited activity against the organisms in varying degrees. In the agar diffusion test, Y. enterocolitica showed the highest zone of inhibition (18 mm at the highest concentration of extract tested (20 mg/mL while E. coli, S. aureus, S. typhi, P. aeruginosa and K. aerogenes showed zones of inhibition of 17, 16, 15, 14 and 16 mm respectively. At extract concentration of 2.5 mg/mL, Y. enterocolitica and P. aeruginosa did not show any zones of inhibition while E.coli, S. aureus, S. typhi, and K. aerogenes showed zones of inhibition of 7, 6, 6 and 7 mm respectively. Below extract concentration of 2.5 mg/mL, there was no zone of inhibition observed with any organism. The MIC of the extract against the organisms was 5 mg/mL except on S. aureus where the MIC was 2.5 mg/mL. The MBC of the extract was 10 mg/mL against Y. enterocolitica, S. typhi, P. aeruginosa and K. aerogenes, 5 mg/mL against E. coli and S. aureus. Preliminary phytochemical testing revealed the presence of tannins, steroids, flavonoids and cardiac glycosides while saponins, alkaloids and anthraquinones were not present. The result gives scientific backing to the use of the leaves by the local people in the treatment of conditions usually associated with the organisms tested.

Utilization of modern contraceptives among female traders in Jos South LGA of Plateau state, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Background: Contraceptive use is seen as pivotal to protecting women’s health and rights, contraception when accepted and used by majority of women in any given community has been shown to reduce unwanted pregnancy, high parity and consequently maternal mortality. Aim: The study aimed at determining the level of awareness, utilization, preferred methods of contraceptives and factors affecting contraceptive use among female traders of Jos south Local government area of Plateau state. Materials and methods: The study was a cross sectional descriptive study that was carried out among female traders within reproductive age group who were not pregnant and consented for the study. Data was generated using a semi-structured interviewer’s administered questionnaire. Result: Two hundred and twelve women were interviewed, their ages ranged from 15-49 years with a mean age of 30+ 3.72. Majority (69.3% were married. The level of awareness of modern contraceptives was high (93.4% and the most popular contraceptive methods were male condom (95.5%, injectable (87.4% and oral contraceptives pills (85.9% while the unpopular methods were female condom (40.4%, cervical diaphragm (17.5%, cervical cap (12.1% and spermicides (12.6%. The prevalence of modern contraceptive utilization was 51.9% while 102 (48.1% were not using any form of contraceptives. Factors found to be associated with contraceptive use among the female traders included marital status (p<0.0001, religion (p<0.0001, education (p=0.048 and parity (p=0.0003. Conclusion: The use of modern contraceptives has remained low despite the high level of awareness of the modern contraceptives among the female traders. Health education on the importance of the use of modern contraceptives should be given to female traders to encourage the use among them.

Juan Carlos Rodríguez y la renovación de marxismo althusseriano  

Directory of Open Access Journals (Sweden)

Full Text Available In the immediate aftermath of 1968, a number of works on Marxist literary theory appeared that were destined to command the attention not only of writers who were re- cognizably ‘Marxist’ or ‘Marxian’ but of others who boasted little in the way of allegiance to the Marxist tradition, however broadly defined. Two such works were Terry Eagleton’s Criticism and Ideology (1976 and Fredric Jameson’s The Political Unconscious (1981. While deeply and confessedly indebted to Louis Althusser for kick-starting their careers, inspirationally speaking, both Eagleton and Jameson were subsequently to reveal an ambiguous, even troubled relation to the French Marxist: Eagleton, through a series of texts that, their unquestionable distinction notwithstanding, run hot and cold in their commitment to ‘Althusserianism’; Jameson, through a brand of Hegelianizing Marxism that finally proved unable to take on board the full complexity of the Althusserian legacy. Preceding both these scholars chronologically, and bearing comparison with them in terms of intellectual range, ambition, and productivity, was Juan Carlos Rodríguez, whose Teoría e historia de la producción ideológica appeared in 1974. Except that there the similarities end, for whereas Eagleton and Jameson were destined to achieve star status within their profession, a rather different career trajectory awaited Rodríguez.

Gamma ray spectroscopy of soil samples from apple orchards in Lamingo dam and Vom area in Jos, Plateau State, Nigeria  

International Nuclear Information System (INIS)

Five samples each were collected from the apple orchards in Lamingo dam and Vom area of Jos East and Jos South local government areas respectively. The samples were allowed to decay for three weeks to ensure efficiency in acquiring the radionuclides. The samples were analyzed using Gamma Ray spectroscopy. Barium- 204 with gamma activity energy level 1765.50keV was used to check the presence of Uranium-235 in the samples. The results showed that samples Lams 2,3,4 and Voms 1,4,5 had high gamma activity energy levels of 2436.356keV, l837.24keV 2928.37 keV and 1656.32keV, 1635.48keV, 2351.87keV respectively as compared to (204B). While Lams 1,5 and Voms 2,3 had relatively lower gamma activity energy levels of 1325.23KeV, 1272.73keV and 1462.61KeV, 1183.24keV respectively. The samples with high gamma activity energy levels imply that radionuclide in the form of 235U is present in trace amounts in the sampled areas. This can affect the output of apples cultivated in such areas as the chemical composition or structure of plants will be altered.

An Assessment of Mining Activities Impact on Vegetation in Bukuru Jos Plateau State Nigeria Using Normalized Differential Vegetation Index (NDVI  

Directory of Open Access Journals (Sweden)

Full Text Available The study area has a pathetic and deplorable condition of landuse/ landcover. The vegetal cover in the area has to be removed from the activities of tin mining which consequently resulted into adverse environmental effect such as erosion. Different forms of human induced stress such as tin mining and heavy rainfall have severely degraded soils on the Jos Plateau. Such degradation problems are also caused by deforestation, inappropriate farming system, bush burning and over-grazing which are hostile to the environment. The impact of tin mining has greatly affected the natural ecology of the study area Bukuru. Micro and macro organisms and plants have been stripped off their natural habitat due to tin mining activities. This paper therefore, assesses the mining activities impact on the vegetation in Bukuru area of Jos plateau in Nigeria. Normalized Differential Vegetation Index (NDVI techniques was adopted to Maps effect of tin mining on the vegetation for the period between 1975 and 2007 using LandSat satellite data. The result of the differential vegetation index analysis reveals a decline in vegetated surfaces in 1986 ranging from 0.04 to 0.58 indicating 0.05 and continuous loss in vegetation over the study area in 2007 (vegetated surface decrease by 0.08 between 1986 and 2007. The decrease in vegetated surface is due to intensive mining and cultivation.

Seroprevalence of fowl pox antibody in indigenous chickens in jos north and South council areas of plateau state, Nigeria: implication for vector vaccine.  

Science.gov (United States)

Fowl pox is a viral disease of domestic and wild birds. The large size of the genome makes it a useful vector for recombinant DNA technology. Although the disease has been described in both commercial and indigenous chickens in Nigeria, data are limited on seroprevalence in free range chickens. Such data are, however, important in the design and implementation of fowl pox virus vector vaccine. We surveyed current antibody status to fowl pox virus in free range chickens by testing 229 sera collected from 10 villages in Jos North and Jos South LGA of Plateau State Nigeria. Sera were analyzed by AGID against standard fowl pox antigen. Fifty-two of the 229 (23%) tested sera were positive for fowl pox virus antibody, and the log titre in all positive specimen was >2. Thirty (21%) and twenty-two (27%) of the samples from Jos South and Jos North, respectively, tested positive. This was, however, not statistically significant (P = 0.30). Generally the study showed a significant level of antibody to fowl pox virus in the study area. This observation may hinder effective use of fowl pox vectored viral vaccine. Fowl pox control is recommended to reduce natural burden of the disease. PMID:23762578

The Juan non-LTR retrotransposon in mosquitoes: genomic impact, vertical transmission and indications of recent and widespread activity  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background In contrast to DNA-mediated transposable elements (TEs, retrotransposons, particularly non-long terminal repeat retrotransposons (non-LTRs, are generally considered to have a much lower propensity towards horizontal transfer. Detailed studies on site-specific non-LTR families have demonstrated strict vertical transmission. More studies are needed with non-site-specific non-LTR families to determine whether strict vertical transmission is a phenomenon related to site specificity or a more general characteristic of all non-LTRs. Juan is a Jockey clade non-LTR retrotransposon first discovered in mosquitoes that is widely distributed in the mosquito family Culicidae. Being a non-site specific non-LTR, Juan offers an opportunity to further investigate the hypothesis that non-LTRs are genomic elements that are primarily vertically transmitted. Results Systematic analysis of the ~1.3 Gbp Aedes aegypti (Ae. aegypti genome sequence suggests that Juan-A is the only Juan-type non-LTR in Aedes aegypti. Juan-A is highly reiterated and comprises approximately 3% of the genome. Using minimum cutoffs of 90% length and 70% nucleotide (nt identity, 663 copies were found by BLAST using the published Juan-A sequence as the query. All 663 copies are at least 95% identical to Juan-A, while 378 of these copies are 99% identical to Juan-A, indicating that the Juan-A family has been transposing recently in evolutionary history. Using the 0.34 Kb 5' UTR as the query, over 2000 copies were identified that may contain internal promoters, leading to questions on the genomic impact of Juan-A. Juan sequences were obtained by PCR, library screening, and database searches for 18 mosquito species of six genera including Aedes, Ochlerotatus, Psorophora, Culex, Deinocerites, and Wyeomyia. Comparison of host and Juan phylogenies shows overall congruence with few exceptions. Conclusion Juan-A is a major genomic component in Ae. aegypti and it has been retrotransposing recently in evolutionary history. There are also indications that Juan has been recently active in a wide range of mosquito species. Furthermore, our research demonstrates that a Jockey clade non-LTR without target site-specificity has been sustained by vertical transmission in the mosquito family. These results strengthen the argument that non-LTRs tend to be genomic elements capable of persistence by vertical descent over a long evolutionary time.

Geochemistry and mineralogy of the Lower Tertiary in situ laterites on the Jos Plateau, Nigeria  

Science.gov (United States)

A geochemical investigation was initated on 24 samples from four different weathering profiles—inselbergs—of the Jos Plateau, Nigeria. Results are presented on field-occurrence, macro- and micro-textures, normative mineralogical composition, kaolinite crystallinity, porosity and density measurements and major and trace element compositions. The polygenetic overprinted profiles, up to 80 m thick, show vertical zonation in soil horizons with very strong Fe- or Al-accumulation in the B ox-horizon that classify them as fossil oxisols whose derivation is related to coastal plains during Lower Tertiary times. The fabriques of the in situ weathering profiles show relic textures according to basaltic or magmatic parent rocks in the lower parts. The upper parts of the sections, where relic textures also partly occur, are mainly characterized by neoformed textures like vesicular, concretionary and spongy textures. In the B ox-horizons, which are in all sections of basaltic origin, lateral facies change is developed. In profiles 9 and 10, this horizon is developed as an iron crust (B ox, fe) and in profiles 12 and 13 as bauxite (B ox, al). Partly or completely maintained relictic minerals in the lower parts of the sections are quartz, zircon, monazite, rutile and opaque heavy minerals. Later eolian transport led to infiltration by illuviation in the upper parts of the profiles with some of these minerals. The mineral composition of the profiles is mainly determined by newly formed minerals like kaolinite, gibbsite, hematite, geothite and anatase. Kaolinte crystallinity values are mostly high except for the B/C-horizons of profiles 9 and 10 as well as for the upper part of the B r-horizon in profile 9. Porosity and density in the B/C- and B r-horizons are relatively monotonous. In the B ox-horizons porosity is reduced and density is mainly in relation to Al- or Fe-minerals. Chemical analysis shows enrichment of elements like Al, Fe, Cr, V and Hf in the B ox-horizons, whereas soluble elements like alkalis and earth-alkalis have been leached out. Beside the preserved relic textures of the parent rocks, the origin of the weathering products is determined geochemically by the discrimination diagram 'Zr/TiO 2: Nb/Y' after Floyd and Winchester (1978, Chem. Geol.21, 291-306).

Assessment of radiological hazards of tin mining and ore processing in Jos, Nigeria  

International Nuclear Information System (INIS)

On the Jos Plateau were found uncontrolled tailing heaps generated from Tin Mining Activities. To assess the associated radiological hazards, an abandoned tailing dump ground was investigated with the residents as the critical population. The mean activity concentrations of 40K, 226Ra and 232Th in the 60 analyzed soil samples were 1251.7±478.4, 3867.5±1282.7 and 8301.9±2862.6 Bqkg-1, respectively with a mean computed dose rate of 7.2±1.6 ?Gyh-1. An annual mean outdoor effective dose of 8.9±0.9mSvy-1 was estimated. Also the activity concentrations of 40K, 226Ra and 232Th in the 60 control soil samples were 447.0±68.0, 37.4±7.4 and 115.4±16.7 Bqkg-1, respectively with a mean dose rate of 0.11±0.01 ?Gyh-1. To account for the internal exposure, vegetables and root crops commonly grown and consumed in the area were assayed. Six varieties of vegetables and five varieties of root crops were analyzed. An internal annual mean effective dose of 148.98±8.14?Svy-1 was estimated. The verification of dose limit compliance for members of the public demands that: External Dose/Dose Limit + Intake (ingested)/ALI (ingestion) + Intake (inhaled)/ALI (inhalation) ? 1. Based on obtained data above, there is non-compliance with the dose limit, since the first term of the compliance formula is much greater than unity. There is therefore a need for an intervention to prevent radiation over exposure of the members of the public. The calculated cancer mortality risk for external and internal exposure scenarios for 226Ra and 232Th were (1.67±0.33) x 10-6(0.00017%) and (3.41±0.14) x 10-6(0.00034%), respectively. The 226Ra radionuclide contributed about 96.09% of the risk in the external scenario with only 3.09% from the 232Th while in the internal, the 226Ra contributed only 70.38%. The combined external and internal (ingestion) risk is (5.08±0.36) x 10-6/year. (author)

Isotopic evidence for the different origins of the Tulum Valley groundwaters (San Juan, Argentina)  

International Nuclear Information System (INIS)

Stable isotope and tritium analyses were used to improve knowledge of the origin of groundwater in the Tulum valley, San Juan province, Argentina. Groundwater is mainly recharged by the San Juan river, which originates in the high Cordillera of the Andes, and is consequently depleted in isotopic content. However, this study led to the conclusion that precipitation over the surrounding hills (altitudes between 1500 and 3000 m), which is isotopically more enriched than the San Juan river source, must be taken into account in evaluating the groundwater inventory in different areas of the valley. About 80 wells covering the whole area, especially the piedmont of the hills, were sampled and analysed to study the regional influence of the different inputs. The interpretation of the results obtained suggests that the San Juan river has recharged most of the groundwater stored in the valley. Tritium levels provide evidence for the present area of recharge, not only limited to the alluvial fan, but also through the river bed in places where particular structural patterns and permeable deposits permit infiltration. The influence of water from Sierra Chica de Zonda, on the eastern border of the valley, is not significant, at least under present conditions. An important contribution of water from Sierra de Pie de Palo is evidenced in the southeast, i.e. groundwater in this area shows isotopic values that are interpreted as a mixture of water from the San Juan river with samples fter from the San Juan river with samples from the Sierra de Pie de Palo springs.

Intrathermocline eddies at the Juan Fernández Archipelago, southeastern Pacific / Remolinos intratermoclina en el Archipiélago Juan Fernández, Océano Pacífico suroriental  

Scientific Electronic Library Online (English)

Full Text Available Se analizaron los resultados de un modelo oceánico regional (ROMS), combinado con información de clorofila-? (Clo-?) y altimetría satelital, además de información proveniente de cruceros oceanográficos, para identificar la interacción entre los remolinos intratermoclina (ITEs) y el Archipiélago Juan [...] Fernández (AJF), y discutir su potencial impacto sobre las concentraciones de Clo-? superficial. El AJF se encuentra ubicado frente a la costa central de Chile (33°S), y está conformado por las islas Robinson Crusoe, Santa Clara y Alejandro Selkirk. Los resultados indican que los remolinos anticiclónicos superficiales y subsuperficiales que interactúan con el AJF se forman principalmente en la zona de transición costera entre 33° y 39°S. Los ITEs se presentan en la región del AJF con una frecuencia semianual, principalmente durante el período de otoño austral, y poseen una débil expresión superficial respecto de los remolinos superficiales adyacentes, un lento desplazamiento (1,16-1,4 km d-1) con dirección noroeste y una estructura coherente por períodos ? 1 año. Durante la interacción de los ITEs con las islas RC-SC y el monte submarino adyacente, se observó una leve (prominente) deflexión del límite superior (inferior) de la termoclina. La escala horizontal (~70-100 km) fue mayor que el radio interno de deformación de Rossby y la escala vertical promedio fue de ~400 m. La interacción entre el ITE de débil expresión superficial identificada con altimetría satelital durante el período de otoño y el AJF perduró durante nueve semanas alcanzando el período invierno. Aproximadamente un mes después del comienzo de la interacción entre el ITE y las islas, se observaron incrementos de Clo-? superficial asociados al remolino con valores hasta tres veces mayores, respecto de las aguas oceánicas adyacentes. Abstract in english Regional Ocean Modeling System (ROMS) results, combined with chlorophyll-? (Chl-?) and satellite altimetry information as well as information from oceanographic cruises were analyzed to identify interactions between intrathermocline eddies (ITEs) and the Juan Fernández Archipelago (JFA), and discuss [...] their potential impact on surface Chl-? concentrations. The JFA is located off the coast of central Chile (33°S), and is composed of three main islands: Robinson Crusoe (RC), Alejandro Selkirk (AS) and Santa Clara (SC). Results indicate that the surface and subsurface anticyclonic eddies that interact with the JFA are formed primarily within the coastal transition zone between 33° and 39°S. ITEs are present within the JFA region with a semiannual frequency, mainly during the austral autumn, and have a weak surface expression in relation to the adjacent surface eddies, with a slow displacement (1.16 to 1.4 km d-1) in a northwest direction and a coherent structure for periods of ? 1 year. During the ITEs' interaction with RC-SC islands and an adjacent seamount, a slight (prominent) thermocline deflection of the upper limit (lower) was observed. The horizontal extent (~70-100 km) was greater than the internal Rossby deformation radius and the average vertical extent was ~400 m. The interaction between the weak surface expression of ITEs, identified with satellite altimetry, and the JFA persisted during autumn for nine weeks until reaching the winter period. Approximately one month after the beginning of the interaction between ITEs and the islands, increases in surface Chl-? associated with the eddy were observed, with values up to three times higher than adjacent oceanic waters.

Natural radionuclides concentrations for soil samples from old mine spoil dumps in Jos and environs, Plateau state Nigeria  

International Nuclear Information System (INIS)

The concentrations of natural radionuclides in soils from around the mining sites in Jos and Bukuru in Plateau State were investigated with an aim of evaluating the environmental radioactivity and radiological health hazards. Concentrations of the primordial radionuclides in the samples were determined by solar MB3 Atomic Absorption Spectrometry (AAS). In the soil types generally, the concentration of ''4''0K is higher than than that of ''2''3''8U and ''2''3''2Th. This could be attributed to natural potassium, which is an essential constituent of soil. The mean values of the concentrations of the primordial radionuclides were found to be ''4''0K (15.50±0.70) ppm, ''2''3''8U (8.55±0.45) ppm and ''2''3''2Th (2.10±0.40) ppm respectively

En el presente trabajo, se definen algunas características hidroquímicas de este sistema hidrográfico, vinculadas a las actividades mineras enunciadas. El desarrollo deltrabajo consistió en un muestreo sistemático del agua del río Castaño para conocer particularmente los niveles de concentración de metales pesados, como cadmio, cinc, cobre, cromo, plomo y aluminio, y determinar su incidencia en la composición y calidad del agua.También se determinaron en laboratorio y campo parámetros tales como: pH, conductividad eléctrica y sólidos disueltos en el agua. Los resultados obtenidos indican que algunos parámetros químicos del agua de río, están vinculados a las variaciones de caudales provocadas por las diferentes estaciones del año y por el régimen de alimentación nival del río Castaño. El agua de este sistema hidrogr áfico no presenta sustancias tóxicas en niveles de contaminación y algunos de los tenores más altos de elementos pesados estarían relacionados con las áreas de afloramientos mineralizados por donde drena el río. Se concluye entonces, que la calidad de este recurso hídrico andino no ha sido afectada por la explotación minera realizada. Abstract in english The province of San Juan, in arid centralwest Argentina, is irrigated by two fluvial systems: the Jachal and San Juan River basins. The Castaño River is one of the two main tributaries to the latter. It crosses the Castaño Viejo mining district, which was a producer of lead, zinc and copper. To inve [...] stigate the water quality and the possible hydrochemical variations given rise by the mining activity, a sampling net was devised along the river course for determining concentrations of calcium, magnesium, sodium, carbonates, bicarbonates, sulphates, cadmium, copper, chrome, lead, zinc, aluminium, pH, dissolved solids and electric conductivity. The results obtained indicate that some chemical parameter of the river water vary in the different seasons of the year. The salinity, dissolved oxygen and biochemical demand of oxygen were found to be low, no toxic substances were detected in significant amounts, and the water quality has not been affected by the mining activity.

Geochemical and Isotopic Estimates of Eolian Dust in Soils of the San Juan Mountains, USA.  

Science.gov (United States)

Eolian dust deposition in the San Juan Mountain Range in southern Colorado has increased 5-7 fold in the past two centuries. This dust deposition contributes an exogenous supply of biologically relevant elements such as Ca, K, Mg, and P to these alpine ecosystems in the form of fine textured mineral particulates. The deposition of eolian dust may be an underestimated factor of soil formation and soil chemistry in these alpine settings. The importance of eolian dust relative to the weathering of local bedrock likely varies across bedrock types. The San Juan Range is geologically diverse with distinct regions of Meso-proterozic crystalline granites in the Weminuche Wilderness, Mesozoic sedimentary layers near Molas Pass in the San Juan National Forest, and Tertiary volcanic geology found on Red Mountain Pass in the Uncompahgre National Forest. Principle component analysis of element chemistry shows that bedrock and soils from these sites cluster by geology. In addition, these groups are chemically distinct from eolian dust collected from snow in the San Juan Range. Several elements seem to drive the difference of dust from soils and bedrock including Ca, Sr, Cu and Cd. The purpose of this research was to estimate the relative contribution of eolian dust to alpine soil element pools in the San Juan Mountains across a range of local geologic parent material. A calculation of element mass- balance shows that Cu and Cd are enriched in the surface soils of both volcanic and sedimentary soils relative to concentrations in local bedrock. However, Ca is enriched only in volcanic soils. These observations support the notion that eolian dust contributes to soil formation and that the relative contribution of dust across the landscape varies with geology. In addition to element mass-balance estimates we utilize Sr and Nd isotope measurements of soil, bedrock, and dust to further constrain the importance of eolian dust to these alpine soils.

Trabalho e bem-estar na polícia da Nigéria a partir dos anos 1980: foco nas divisões de polícia de Jos / Work and welfare in the Nigeria police since the 1980s: focus on Jos police divisions  

Scientific Electronic Library Online (English)

Full Text Available A polícia é uma metáfora para a crise sistêmica enfrentada pela Nigéria, especialmente desde o início da década de 1980. A crise foi anunciada pelo colapso econômico ocasionado pela má gestão e corrupção na indústria do petróleo. A intervenção do Fundo Monetário Internacional exigiu cortes em vários [...] setores, inclusive no de segurança. Ironicamente, este foi também o período em que a necessidade de intervenção do setor de segurança foi mais urgente. Aliado ao tipo de governança - com regras militares -, a polícia foi imensamente negligenciada como a principal força para a defesa da lei e o controle da crise. As condições de trabalho e de bem estar, determinantes fundamentais da produtividade, deterioraram-se junto com a expectativa crescente dos nigerianos em relação à polícia em meio à criminalidade crescente e ao colapso da ordem. Por meio de entrevistas, observações e anedotas, contadas principalmente pelos funcionários trabalhando em Jos, este artigo examina as condições de trabalho e de bem estar da polícia. Ele argumenta que a piora das condições de trabalho da polícia ocorre em função do declínio econômico, da corrupção e da preferência por um tipo de regime. Conclui-se apelando pela melhora das condições de trabalho e de bem estar como peças fundamentais para o bom desempenho da polícia.

Work and welfare conditions, key determinants of productivity, deteriorated as the expectation of Nigerians of the police heightened amidst growing crime and breakdown of order. Using interviews, observations and anecdotes particularly in Jos from serving personnel, the paper examines work and welfare conditions of the police. It argues that the worsening working conditions of the police is a function of economic decline, corruption and regime type preference. It concludes by calling for improve working and welfare condition as cornerstone for police performance.

Ästhetisches Bild und Christliche Mystik im Cántico espiritual des San Juans de la Cruz  

DEFF Research Database (Denmark)

  In diesem Zusammenhang werde ich, von dem Cántico espiritual des San Juans de la Cruz (1577) ausgehend und zentrale rezeptionsgeschichtliche Probleme einbeziehend, den mystischen Bildbegriff untersuchen. Auf der einen Seite bildet San Juans selbstständige Interpretation des biblischen Hoheliedes mit ihrem farbigen Bilderreichtum einen ausgezeichneten Ausgangspunkt für die Diskussion des komplizierten Verhältnisses zwischen dem Profanen und dem Heiligen, das sich in dem grundlegenden Schisma der San Juan-Rezeption spiegelt; auf der anderen Seite ist das Problem der Funktion des ästhetischen Bildes im Fall Cántico besonders aktuell, weil San Juan sich bewußt in eine lange christliche Tradition, Hohelied-Auslegung mit bildtheoretischer Diskussion zu verbinden, einschreibt. Eine Untersuchung der Anatomie und Funktion des ästhetischen Bildes in der mystichen Dichtung des San Juans de la Cruz macht somit den übergeordneten Rahmen meiner Interpretation und Diskussion des Cántico espiritual mit dazugehörigen Prosakommentaren aus. Weil der Cántico espiritual als mysticher Text behauptet, er beschreibt eine paranormale Erfahrung (die unio mystica als intenses Gotteserlebnis), ist es relevant, die literarische Repräsentation genauer zu untersuchen und u.a. einzuschätzen, ob man die mystische Liebesdichtung des San Juans notwendigerweise im Rahmen einer Symbolästhetik verstehen muß, so wie die Majorität der profanen Interpreten behauptet. Der mystiche Text treibt irgendwie die Frage der Repräsentation auf die Spitze, und fordert eine Reflexion der Bild- oder Repräsentationsproblematik, die meiner Meinung nach ganz zentral für das Verständnis des komplizierten Verhältnisses zwischen dem Profanen und dem Heiligen als thematischen Problems und der Emblem-artigen Dualität von Bild und Schrift als formalen Problems ist.

Neotectónica de la provincia de San Juan, centro-oeste de Argentina / Neotectonics in the San Juan province, central-western Argentina  

Scientific Electronic Library Online (English)

Full Text Available SciELO Mexico | Language: Spanish Abstract in spanish La provincia de San Juan, en el centro-oeste de Argentina, posee numerosas evidencias de fallas con actividad tectónica cuaternaria. Las discontinuidades estructurales a lo largo de Cordillera Frontal, Precordillera y Sierras Pampeanas, determinan las diferentes características superficiales de las [...] deformaciones cuaternarias, que a la vez producen distintos escenarios paleosísmicos. La mayor parte de estas deformaciones y estructuras sismogénicas, actualmente conocidas en el territorio argentino, se ubican dentro de un cinturón sísmico definido entre Cordillera Frontal y Sierras Pampeanas Occidentales (27º ? 33º de latitud sur). Esta región también constituye un área con interacciones complejas entre estilos estructurales de piel fina y gruesa. Los sismos más destructivos en los últimos 120 años (M 7.5, en octubre de 1894; M 7.0, en enero de 1944; 6.8, en junio de 1952; y M 7.4 en noviembre de 1977) se han ubicado en esta zona. En este trabajo se presenta una síntesis del estado del conocimiento neotectónico de la provincia de San Juan, con los resultados de los últimos estudios sobre fallas con actividad tectónica cuaternaria en la región. Abstract in english San Juan province in central-western Argentina shows evidence of active faulting affecting Quaternary sediments. The structural discontinuities along the Frontal Cordillera, Precordillera and Sierras Pampeanas foothills determine the different superficial characteristics of the Quaternary deformatio [...] ns, which in turn produce different paleoseismic scenarios. Most the Quaternary deformations and seismogenic structures currently known in Argentina are located within a seismic belt including the Precordillera and the Western Pampean Ranges (27º ? 33º south latitude). This area also constitutes a setting with complex interactions between thin-skinned and thick-skinned structural styles. The most destructive earthquakes of the last 120 years (M 7.5, October 1894; M 7.0, January 1944; 6.8, June 1952; and M 7.4, November 1977) were located in this region. This paper presents an overview of the state of knowledge on the neotectonics of the San Juan province, with the results from recent studies on faults with Quaternary tectonic activity in the region.

Paleoenvironmental interpretation using fossil record: San Juan Raya Formation, Zapotitlán basin, Puebla, Mexico / Interpretación paleoambiental empleando el registro fósil: Formación San Juan Raya, cuenca de Zapotitlán, Puebla, México  

Scientific Electronic Library Online (English)

Full Text Available La Formación San Juan Raya es mundialmente reconocida debido a su alta diversidad y abundancia fosilífera. En este estudio se reconocieron e interpretaron nueve biofacies y tres icnofacies tomando como base la influencia de diversos factores como los cambios relativos en el nivel del mar, la tasa de [...] sedimentación, la salinidad del agua y la consistencia del substrato. Entre estos factores, al parecer las variaciones en la salinidad del agua fueron muy importantes en el desarrollo y remplazo de las asociaciones de organismos. La mayor parte de los organismos que conformaron las distintas biofacies e icnofacies, habitaron en ambientes de zona de rompiente y de plataforma interna. El objetivo de este trabajo es el de proveer una reconstrucción de las diferentes comunidades bentónicas y de los ambientes de depósito de un sector de la Formación San Juan Raya durante el Cretácico Temprano. Los resultados indican que el modelo paleoambiental del área de estudio corresponde a un sistema clástico marino somero dominado por tormentas. Finalmente, a lo largo de los 765.5 m de la columna estratigráfica compuesta, se identificaron nueve ciclos transgresivos-regresivos, en los cuales las etapas de somerización se encuentran en los niveles de 200 y 500 m, mientras que las condiciones de mayor profundidad están ubicadas en los 300, 400 y 765.5 m respectivamente. Abstract in english The San Juan Raya Formation is world-wide recognized because of the high diversity and abundance of fossils. In this study nine biofacies, three ichnofacies and ten lithofacies were recognized and interpreted on the basis of the influence of several environmental factors such as water depth change, [...] sedimentation rate, water salinity and substrate consistency. Among these factors, salinity variations were apparently crucial for developing and replacement of the different biofacies. Most of biofacies and ichnofacies inhabited in subtidal, shoreface and inner shelf zones. The aim of this investigation is to provide a comprehensive reconstruction of the different faunal benthonic assemblages and paleoenvironments in a sector of the San Juan Raya Formation during Early Cretaceous time. The results indicate that the paleoenvironmental model for the study area corresponds to a shallow marine, open-coast, storm-dominated clastic system, characterized by several variations in subenvironments, from foreshore to offshore. Along a measured composite column of about 765.5 m in length, nine cycles of transgression-regression were identified, with the shallowest stage at the 200 and 500 m levels and the deepest conditions at 300, 400 and 765.5 m in the column.

Impacts of Urbanization in the Coastal Tropical City of San Juan, Puerto Rico  

Science.gov (United States)

Urban sprawl in tropical locations is rapidly accelerating and it is more evident in islands where a large percentage of the population resides along the coasts. This paper focuses on the analysis of the impacts of land use and land cover for urbanization in the tropical coastal city of San Juan, in the Caribbean island of Puerto Rico. A mesoscale numerical model, the Regional Atmospheric Modeling System (RAMS), is used to study the impacts of land use for urbanization in the environment including specific characteristics of the urban heat island in the San Juan Metropolitan Area (SJMA), one of the most noticeable urban cores of the Caribbean. The research also makes use of the observations obtained during the airborne San Juan Atlas Mission. Surface and raw insonde data from the mission are used to validate the atmospheric model yielding satisfactory results. Airborne high resolution remote sensing data are used to update the model's surface characteristics in order to obtain a more accurate and detailed configuration of the SJMA and perform a climate impact analysis based on land cover/land use (LCLU) changes. The impact analysis showed that the presence of the urban landscape of San Juan has an impact reflected in higher air temperatures over the area occupied by the city, with positive values of up to 2.5 degrees C, for the simulations that have specified urban LCLU indexes in the model's bottom boundary. One interesting result of the impact analysis was the finding of a precipitation disturbance shown as a difference in total accumulated rainfall between the present urban landscape and with a potential natural vegetation, apparently induced by the presence of the urban area. Results indicate that the urban-enhanced cloud formation and precipitation development occur mainly downwind of the city, including the accumulated precipitation. This spatial pattern can be explained by the presence of a larger urbanized area in the southwest sector of the city, and of the approaching northeasterly trade winds.

The paradigm of paraglacial megafans of the San Juan river basin, Central Andes, Argentina  

Science.gov (United States)

The spatial distribution and several morphometric characteristics of the Quaternary alluvial fans of the San Juan River, in the province of San Juan, at the Central and Western part of Argentina, have been studied to classify them as paraglacial megafans, as well to ratify its depositional environmental conditions. The high sedimentary load exported by San Juan river from the Central Andes to the foreland depressions is estimated about 3,682,200 hm3. The large alluvial fans of Ullum-Zonda and Tulum valleys were deposited into deep tectonic depressions, during the Upper Pleistocene deglaciation stages. The outcome of collecting remotely sensed data, map and DEM data, geophysical data and much fieldwork gave access to morphometric, morphographic and morphogenetic data of these alluvial fans. The main drainage network was mapped on processed images using QGis (vers.2.0.1). Several fan morphometric parameters were measured, such as the size, the shape, the thickness, the surface areas and the sedimentary volume of exported load. The analyzed fans were accumulated in deep tectonic depressions, where the alluvium fill reaches 700 to 1200 m thick. Such fans do not reach the large size that other world megafans have, and this is due to tectonic obstacles, although the sedimentary fill average volume surpasses 514,000 hm3. The author proposes to consider Ullum-Zonda and Tulum alluvial fans as paraglacial megafans. According to the stratigraphic relationships of the tropical South American Rivers, the author considers that the San Juan paraglacial megafans would have occurred in the period before 24 ka BP , possibly corresponding to Middle Pleniglacial (ca 65-24ka BP). They record colder and more humid conditions compared with the present arid and dry conditions.

Assessing Climate Variability Effects on Dengue Incidence in San Juan, Puerto Rico  

Directory of Open Access Journals (Sweden)

Full Text Available We test the hypothesis that climate and environmental conditions are becoming favorable for dengue transmission in San Juan, Puerto Rico. Sea Level Pressure (SLP, Mean Sea Level (MSL, Wind, Sea Surface Temperature (SST, Air Surface Temperature (AST, Rainfall, and confirmed dengue cases were analyzed. We evaluated the dengue incidence and environmental data with Principal Component Analysis, Pearson correlation coefficient, Mann-Kendall trend test and logistic regressions. Results indicated that dry days are increasing and wet days are decreasing. MSL is increasing, posing higher risk of dengue as the perimeter of the San Juan Bay estuary expands and shorelines move inland. Warming is evident with both SST and AST. Maximum and minimum air surface temperature extremes have increased. Between 1992 and 2011, dengue transmission increased by a factor of 3.4 (95% CI: 1.9–6.1 for each 1 °C increase in SST. For the period 2007–2011 alone, dengue incidence reached a factor of 5.2 (95% CI: 1.9–13.9 for each 1 °C increase in SST. Teenagers are consistently the age group that suffers the most infections in San Juan. Results help understand possible impacts of different climate change scenarios in planning for social adaptation and public health interventions.

Upper Cretaceous - lowermost Miocene lithostratigraphic units exposed in Alba Iulia-Sebes-Vintu de Jos area (SW Transylvanian Basin  

Directory of Open Access Journals (Sweden)

Full Text Available A main area where several Uppermost Cretaceous-Lower Cenozoic formations are exposed in the SW Transylvanian Depression is the region outlined by the localities Alba Iulia, Sebe?, Vin?u de Jos (Alba district. In Maastrichtian, continental formations belonging to the post-Laramian cover began their deposition. In Early Cenozoic, the dominance of continental formations continued, but some short marine transgress events occur too, with specific marine and brackish deposits interbedded into the continental successions. Some new lithostratigraphic units are proposed: Vurp?r (Maastrichtian, ?ard (Maastrichtian-Late Eocene, B?r?ban? (Oligocene and Sântimbru (Aquitanian formations. Ighiu Fm. (Late Eocene-Early Oligocene is also reinterpreted. This region is an outstanding one for the fossil vertebrate heritage too due to the Uppermost Cretaceous (Maastrichtian dinosaur fauna discovered into Vurp?r and ?ard formations, very similar with the famous faunas described by Nopcsa from Ha?eg Basin. The autochthony of these fossils is obvious. In this context, some corrections should be done on several older geological maps, where these deposits correspond to erroneous geological ages.

Measurement of radionuclides concentration of some commonly consumed vegetables and the soil samples in Jos and Bukuru metropolis, Plateau state  

International Nuclear Information System (INIS)

Studies of radiation level and radionuclide distribution in soil and vegetables of Bukuru and Jos metropolis in Plateau State, Nigeria, were undertaken to provide baseline data for the assessment of the impact of radionuclides which occur as a result of the tin mining activity that was set up in the region and to understand the behaviour of the radionuclides in the soil as well as the uptake of these radionuclides by the vegetables which are commonly consumed in the area. As part of this project the concentration of three important natural radionuclides namely: ''4''0K, ''2''3''2Th and ''2''3''8U have been measured in a number of geological samples and biological samples using the Atomic Absorption Spectrometry (AAS). The measurement showed that ''4''0K activity concentration is mostly high in the leafy vegetables with an average value of (17.04±0.04) ppm possibly as a result of its double intake both from the root uptake and from the atmosphere. While the ''2''3''8U and ''2''3''2Th are minimal in the leafy vegetables with an average value of (2.06±0.01) ppm and (0.29±0.02) as well as in the root vegetables. Though these could be higher relative to their expected values in normal soil due to fertilizer applications and washed tailings into the streams where the vegetables are mostly farmed

Marine Geology of the Southwestern San Juan Islands: New Insights From Multibeam Imagery and Processed Aeromagnetic Data  

Science.gov (United States)

The San Juan Islands, located in the seismically active northern Puget Sound, have a complicated and not yet fully understood geologic history. This study is among the first marine geologic mapping efforts within the San Juan Islands, filling an important gap in an otherwise well-studied region. Existing geologic and geophysical data were combined with interpretations of new multibeam bathymetry and backscatter seafloor imagery to construct a seamless onshore - offshore geologic map of the southwestern San Juan Islands. Simrad EM1002 (95 kHz) and Reson 8101 (240 kHz) multibeam bathymetry and backscatter data were collected between October 2000 and November 2003 within Haro Strait, northeastern Strait of Juan de Fuca, and San Juan Channel. Sun-shaded images of the processed data reveal a complex network of faulted and fractured bedrock exposures, deep glaciated channels, Pleistocene glacial sediments, and dynamic bedforms. Distinct slump morphologies in multibeam and backscatter imagery suggest active slumping of recent sediments at the mouth of San Juan Channel. A number of previously inferred offshore geologic structures were extended and constrained based on distinct linear bedrock features visible in the multibeam imagery. Aeromagnetic data collected by the U.S. Geological Survey in 1997 were processed to accentuate short-wavelength, presumably shallow, magnetic sources. The resultant derivative aeromagnetic map reveals a number of areas with distinctive anomaly patterns. Gradients in magnetic anomalies often corresponded with fault traces identified in high-resolution multibeam imagery and may reflect slight magnetic susceptibility contrasts across fault contacts. Aeromagnetic data also constrain two tectonostratigraphic terrane boundaries not identified in multibeam imagery: 1) the Buck Bay fault, which separates the Lopez Structural Complex and Decatur terrane from the underlying Constitution Formation, and 2) the Haro fault separating the Deadman Bay terrane of the San Juan Thrust system from the Wrangellia terrane on Vancouver Island.

"Donde tu hermosura se ensombra": problemas morfosemánticos en el "Comentario VII", de Juan Gelman / "Donde tu hermosura se ensombra": Morpho Semantic Problems on "Comentario VII", of Juan Gelman  

Scientific Electronic Library Online (English)

Full Text Available SciELO Mexico | Language: Spanish Abstract in spanish Con las herramientas que brinda la descripción morfológica, en el presente trabajo se describen formal y semánticamente las licencias poéticas y arcaísmos que se encuentran en el poema "Comentario VII", de Juan Gelman; esto es, aquellas palabras ocasionales que el poeta acuña con una finalidad emoti [...] va y poética, así como las palabras que han caído en desuso y se han revitalizado en su poesía. El análisis toma como punto de partida el concepto de transparencia y opacidad morfológica, en virtud de que la formación de palabras en este poema estará condicionada, entre otras cosas, por el hecho de que el lector pueda identificar la palabra base de la licencia poética, situación que le permitirá determinar el significado de la misma. Además, algunas de estas licencia poéticas rivalizarán con palabras establecidas de la lengua, de manera que la licencia poética no será bloqueada, porque a partir de la transparencia Juan Gelman logrará restituir los significados básicos o prototípicos que las palabras establecidas han dejado de expresar. Finalmente, se muestra cómo se favorece la argumentación literaria con el empleo de herramientas propias de la descripción lingüística. Abstract in english In this paper, the author uses the tools of linguistics and morphology to describe formally and semantically the poetic licenses and archaisms found in the poem "Comentario VII" by Juan Gelman: that is, those occasional words coined by Gelman with emotional and poetic purpose, as well as words that [...] have become obsolete but have found themselves revitalized in his poetry. The analysis takes as its starting point the concept of morphological transparency and opacity, through which the formation of words in the poem is conditioned, among other things, by the fact that the reader can identify the base word of poetic license, an identification that allows him to determine the base word's meaning. Similarly, some of these words will contend with both formally and semantically established words in such a way that poetic license will not be blocked, as through transparency Gelman will succeed in restoring basic or prototypical meanings that words no longer express. Finally, the author shows how literary argument is supported by the use of tools of linguistic description.

Taxonomy and biogeography of the coastal fishes of Juan Fernández Archipelago and Desventuradas Islands, Chile / Taxonomía y biogeografía de los peces costeros del Archipiélago de Juan Fernández y de las islas Desventuradas, Chile  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: English Abstract in spanish Las islas Desventuradas (San Félix y San Ambrosio) y del Archipiélago de Juan Fernández (Robinson Crusoe y Alejandro Selkirk) son islas oceánicas de origen volcánico ubicadas en el Pacífico Sudeste, frente a Chile. Sobre la base de material recolectado desde 1997 hasta la fecha, revisiones de colecc [...] iones de las expediciones del R/V Anton Bruun y actualizaciones taxonómicas, la fauna de peces litorales del Archipélago de Juan Fernández y las islas Desventuradas tienen un total de 52 especies, con 41 y 43 especies, respectivamente. Los peces costeros endémicos de Juan Fernández son solamente cinco (12,2%) y tres son las especies registradas aquí como nuevas para las islas (Gymnothorax cf. obesus, Gnathophis sp., Suezichthys sp.). Las Desventuradas tienen solamente dos especies endémicas (4,6%) y cuatro son los nuevos registros (Scorpaenodes englerti, Maxillicosta reticulata, Suezichthys sp., Aseraggodes bahamondei). El reducido número de especies endémicas para Juan Fernández comparado con trabajos previos (15 especies) se debe a que muchas resultaron ser endémicas de ambos grupos de islas (22 especies = 42,3% total peces litorales), apoyando la propuesta que ambos grupos de islas debieran formar una sola unidad biogeográfica. La extensión oriental de la región Indo Pacífico Oeste para incluir la cordillera de Nazca, las islas Desventuradas y Juan Fernández encuentra apoyo en este trabajo. La afinidad zoogeográfica entre las Desventuradas y las islas del Pacífico Oeste (Isla de Pascua hasta Australia) incluye 16 especies, agregando cinco nuevos registros a listas anteriores. Filogenias de tres géneros señalan un centro de origen en el Pacífico Oeste, con uno o más eventos de dispersión hacia las islas Desventuradas y Juan Fernández. Este patrón de dispersión puede repetirse en otros siete géneros de pocas especies y relativamente restringidas en distribución. Solo una filogenia (Odontesthes) propone un origen continental con una dispersión hacia el Oeste, sin embargo otros tres géneros parecen tener este mismo patrón de dispersión. Abstract in english The Desventuradas Islands (San Félix and San Ambrosio) and Juan Fernández Archipelago (Robinson Crusoe and Alejandro Selkirk) are oceanic islands of volcanic origin located in the southeastern Pacific off Chile. Based on new material collected since 1997, revision of the R/V Anton Bruun expeditions [...] collections, and a taxonomic update, the coastal fish fauna of Juan Fernández Archipelago and Desventuradas Islands found a total of 52 species, with 41 and 43 species, respectively. The number of coastal fish species recorded herein as endemic for Juan Fernández is only five (12,2%) and three species are new records (Gymnothorax cf. obesus, Gnathophis sp., Suezichthys sp). The Desventuradas Islands have only two endemic species (4,6%) and four species are new records (Scorpaenodes englerti, Maxillicosta reticulata, Suezichthys sp., Aseraggodes bahamondei). The reduced number of endemic species for the Juan Fernández Islands as compared with previous accounts (15 species) is the result that more species were found to be endemic to both islands groups (22 species = 42,3% all coastal fishes), suggesting these two island groups should be considered a single biogeographic unit. The eastern extension of the Indo West Pacific Region to include the Nazca Ridge, Desventuradas and Juan Fernández Islands is supported herein. The zoogeographical affinities between Desventuradas and western Pacific Islands (Easter Island to Australia), includes 16 species, adding five new species to previous lists. Relationships of three genera indicate a Western Pacific origin with one or more dispersal events to the Desventuradas and Juan Fernández Islands. Another seven genera, with relatively few species and restricted distribution, may have this same pattern. Only one phylogenetic study indicates a continental origin with a westward dispersal (Odontesthes), however another thr

Contaminants of antropic origin in groundwater San Juan (Argentina). Vulnerability and hydro chemical indicators; Contaminantes de origen antropico en aguas subterraneas San Juan (Argentina)  

Energy Technology Data Exchange (ETDEWEB)

The Tulum Valley aquifer vulnerability and its correlation with the behavior of hydro chemical parameters related to new urban neighborhoods and uncontrolled waste disposal are discussed. A high vulnerability to contamination by substances solved in the recharge water at the San Juan river shore is estimated. A fast transport rate due to the high permeability is foreseen, as well as the existence of contamination sources related to waste disposals and populations without a sewer system. The results show that the mentioned populations and waste disposal sites are located at vulnerable zones of the area. A higher concentration of nitrates and nitrites is observed at the Southeast, due to the short permanency period of the water in the system, and to the reconcentration in zones with less permeable levels.

Darriwilian bryozoans from the San Juan Formation (Ordovician), Argentine Precordillera / Briozoos darriwilianos de la Formación San Juan (Ordovícico) de la precordillera argentina  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: English Abstract in spanish Se ha realizado un estudio taxonómico detallado de la fauna de briozoos de los niveles superiores (Darriwiliano) de la Formación San Juan en las secciones de Talacasto y Cerro Viejo, Precordillera Argentina. Se describen tres géneros y se definen dos nuevas especies: Lamottopora multispinosa sp. nov [...] ., Aostipora sanjuanensis sp. nov. y Phylloporinidae sp. indet. Se discute el significado paleoecológico de la fauna de briozoos. Los briozoos ramosos como Lamottopora y Aoistopora dominan en la sección de Talacasto. Algunas colonias vivieron fijadas directamente sobre el sustrato, aunque también aparecen como epibiontes sobre la superficie de esponjas, que son muy abundantes en este intervalo. En la sección de Cerro Viejo los briozoos se encuentran mayoritariamente adheridos a la superficie de las esponjas, mientras que algunos fragmentos de briozoos ramosos, incluyendo dos colonias del briozoo reticulado Phylloporinidae sp. indet, aparecen en el sedimento. La presencia de estas formas delicadas en el Cerro Viejo es una nueva evidencia de la baja energía del agua como fue sugerido para estos niveles. En las calizas de la Formación San Juan sólo el género laminar Nicholsonella aparece en niveles algo más antiguos (Floiano). Esta baja diversidad muestra un desajuste con las curvas globales de diversidad del grupo. La primera radiación local (géneros), descripta en esta contribución, es también significativamente menor y muestra un desacople con la diversificación que experimenta el grupo para este mismo intervalo temporal en otras regiones. Abstract in english A detailed study is carried out on the taxonomy of the bryozoan fauna from the upper levels of the San Juan Formation (Darriwilian) in the Talacasto and Cerro Viejo sections, Argentinean Precordillera. Three bryozoan genera are described and two new species are erected: Lamottopora multispinosa sp. [...] nov., Aostipora sanjuanensis sp. nov., and Phylloporinidae sp. indet. The paleoecological significance of the bryozoan fauna is discussed. The ramose bryozoans Lamottopora and Aostipora dominate in the Talacasto section. Some colonies probably lived attached directly to the substrate, while others occur attached to the surface of the abundant sponge fauna in the section. The majority of bryozoans at the Cerro Viejo section occur as epibionts, with bases attached to the surface of sponges. Bryozoans collected in the matrix are scarce compared to the Talacasto section, and comprise a few fragments of ramose bryozoans and two small fragments of the reticulate Phylloporinidae sp. indet were recorded exclusively in this locality. The presence of this delicate form in Cerro Viejo is further evidence of the quiet water conditions suggested for these levels. Only the laminar form Nicholsonella occurs in slightly older levels (Floian) of the San Juan Formation. The low diversity recorded here shows a slight decoupling with the global pattern. The first local radiation (three genera) is minor compared with the important radiation that the phylum experienced elsewhere.

Project "Conservation, Restoration, and Development of the Juan Fernández islands, Chile" / Proyecto conservación, restauración y desarrollo de las islas Juan Fernández, Chile  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: English Abstract in spanish Las islas Juan Fernández albergan una de las floras más interesantes del planeta desde el punto de vista científico. Aunque están protegidas como Parque Nacional y Reserva Mundial de la Biosfera, más de 400 años de intervención humana han dejado una profunda huella en sus comunidades de plantas nati [...] vas. Los repetidos incendios, sobreexplotación de especies y la introducción de plagas animales y vegetales, han colocado al 75 % de la flora vascular endémica bajo amenaza de extinción. En 1997, la Corporación Nacional Forestal de Chile (CONAF) dio inicio a un ambicioso proyecto, cuyo propósito es recuperar este ecosistema de alta complejidad a través de un enfoque socio-ecológico. Juan Fernández constituye un caso interesante, debido a que la población local (600 personas) prácticamente vive dentro del parque, por lo que no es posible excluir al humano de los programas de conservación. Segundo, el relativamente pequeño tamaño del archipiélago (100 km²) permite la observación de los efectos de cualquier modificación en el ecosistema en pequeñas escalas en el tiempo y el espacio. Tercero, la biota nativa e introducida se relaciona de tal manera que la modificación de la abundancia de una especie por acción humana puede provocar resultados inesperados en otras especies no consideradas blanco. El proyecto comprende principalmente programas que buscan controlar o erradicar algunas de las plagas animales y vegetales, adopta medidas activas para conservar y restaurar la flora, así como también inserta al humano en los planes de conservación. En este trabajo se da a conocer la problemática general del parque, la estrategia que se ha seguido para resolver estos problemas, así como también se informan los primeros resultados. Este proyecto ilustra la complejidad para realizar labores de conservación en una situación práctica, con variadas y complejas interrelaciones, y con vacíos en el conocimiento ecológico. Por lo tanto, puede servir como modelo para realizar programas similares en otros lugares Abstract in english From a scientific point of view, the Juan Fernández islands contain one of the most interesting floras of the planet. Although protected as a National Park and a World Biosphere Reserve, 400 years of human interference have left deep traces in the native plant communities. Repeated burning, overexpl [...] oitation of species, and the introduction of animal and plant plagues have taken 75 % of the endemic vascular flora to the verge of extinction. In 1997, Chile's national forest service (Corporación Nacional Forestal, CONAF) started an ambitious project, whose objective is the recovery of this highly complex ecosystem with a socio-ecological focus. Juan Fernández makes an interesting case, as the local people (600 persons) practically live within the park, therefore impeding the exclusion of the people from any conservation program. Secondly, the relatively small size of the archipelago (100 km²) permits the observation of the effects of whatever modification in the ecosystem on small scales in time and space. Thirdly, the native and introduced biota are interrelated in such a way that human-caused changes in one species population may provoke unexpected results amongst other, non-target species. The project mainly deals with the eradication or control of some animal and plant plagues, the active conservation and restoration of the flora and the inclusion of the local people in conservation planning. This article presents the park's general problems, the strategy proposed to resolve them as well as some preliminary results. This project shows the complexity of the conservation activities in practice, with diverse and complex interrelations and gaps in ecological knowledge. In this respect, the project may well serve as a model for similar programs in other places

Subtidal reef fish and macrobenthic community structure at the temperate Juan Fernández Archipelago, Chile / Estructura comunitaria del macrobentos y peces costeros submareales del archipiélago Juan Fernández, Chile  

Scientific Electronic Library Online (English)

Full Text Available El archipiélago Juan Fernández (33°37'S, 78°51'W), es un grupo de islas situadas a 650 km al oeste de Chile continental, con alto grado de endemismo en su biota marina. A pesar de numerosas expediciones científicas a estas islas que han identificado este alto endemismo, pocos estudios han tratado de [...] identificar los patrones de estructura de la comunidad en hábitats submareales. Mediante censos visuales, se registraron los peces y su asociación con el hábitat en cinco sitios de estudio, en dos de las tres islas del archipiélago. Dado el aislamiento del archipiélago nos preguntamos: ¿Cuál es la composición de la fauna de peces de arrecife en estas aisladas islas? ¿Qué hábitats dominan los ambientes submareales? ¿Qué influye en la abundancia de peces de arrecife? Los análisis realizados sugieren que la comunidad de peces en el archipiélago está dominada por especies endémicas. La ictiofauna se compone de una mezcla de taxa de origen subtropical y templado, con una mayor similitud a las especies del Pacífico occidental que a las del Pacífico suroriental. Se identificaron diferentes ensambles de peces en sitios expuestos y protegidos. Las macroalgas pardas y rojas limitaron la abundancia de algunos peces de arrecife. Cuatro categorías tróficas de peces de arrecife, estuvieron presentes en el archipiélago, siendo los invertívoros los consumidores dominantes. Hasta donde se sabe, este es el primer intento en identificar los patrones de la estructura comunitaria en ambientes submareales en el archipiélago de Juan Fernández. Abstract in english The Juan Fernández Archipelago (33°37'S, 78°51'W), an isolated group of islands 650 km west of continental Chile, has a high degree of endemism in its marine biota. Despite numerous scientific expeditions to these islands that have identified this high endemism, few studies have attempted to identif [...] y patterns of community structure in subtidal habitats. Using visual census, we surveyed fish and habitat associations at five sites located at two of the three islands of the archipelago. Given the isolation of the archipelago we asked: What is the composition of the reef fish fauna at these isolated islands? What habitats dominate subtidal environments? What influences the abundances of reef fishes? Our analysis confirms that fish communities at the archipielago are dominated by endemic species. The ichthyofauna is comprised of a mixture of subtropical and temperate taxa, with greater similarity to western than eastern South Pacific fauna. We identified different fish assemblages at wave-exposed and wave-sheltered sites. Brown and red macroalgae were correlated with the abundances of some reef fishes. Four broad trophic categories of reef fishes were present at the archipelago, with invertebrate consumers dominating abundance. To our knowledge, this is the first attempt to quantify patterns of community structure in subtidal environments at the Juan Fernández Archipelago.

Diagnóstico y caracterización del arbolado del bosque de San Juan de Aragón / Diagnosis and characterization of the trees of the San Juan de Aragón forest  

Scientific Electronic Library Online (English)

Full Text Available SciELO Mexico | Language: Spanish Abstract in spanish Las ciudades son consideradas los ecosistemas más artificiales sostenidos por el hombre y se ha demostrado que en ellas se generan serios problemas ambientales. Por otra parte, la dasonomía urbana permite el estudio, manejo y mantenimiento de las especies arbóreas que se han establecido en áreas urb [...] anas; por ello, se realizó un diagnóstico general del Bosque de San Juan de Aragón, mediante un inventario completo de su arbolado, en el que se incluyeron variables cuantitativas y cualitativas. Se contabilizaron 88 especies, de las cuales siete representan 73.67% de los árboles; la etapa de desarrollo más común corresponde a árboles maduros (58.33%), seguida por la etapa juvenil (41.18%); en cuanto a la condición de vigor, 59.95% corresponde a los individuos vigorosos y 28.72% a declinaciones incipientes, mientras que el estado físico y sanitario del tronco y copa están dominados por las categorías bueno y regular. Se registraron 5 252 ejemplares que requieren, al menos, algún tipo de poda: las de restauración y limpieza son las más necesarias. El arbolado con riesgo asociado fue de 7.9% y solo 3.14% presentó algún tipo de fauna. En general, los bosques urbanos muestran baja diversidad de especies; sin embargo, la condición general del Bosque de San Juan de Aragón se admite como buena. Abstract in english Cities are considered the most artificial man-made ecosystems and have been shown to be the cause of serious environmental hazards. It is therefore crucial to preserve the urban green areas. On the other hand, urban forest science allows the study, management and maintenance of the tree species that [...] have been established in the cities. For this reason, a general diagnosis of the San Juan de Aragón Forest (Bosque San Juan de Aragón, BSJA) was carried out by means of a complete inventory of its trees, in which both quantitative and qualitative variables were included. 88 species were identified, of which seven account for 73.67% of the trees. The most common stage of development of the trees is maturity (58.33%), followed by youth (41.18%). As for their vigor, 59.95% are vigorous trees, while 28.72% show an incipient decline; the physical and sanitary condition of the stem and crown are dominated by the "good" and "fair" categories. 5 252 specimens were found to require at least some type of pruning; restorative and hygienic pruning are the most needed. The proportion of trees with an associated risk was 7.9%, and only 3.14% had some type of fauna. Overall, urban forests show a low diversity of species; however, their general condition is considered to be good.

Estructura del paleozoico inferior en las nacientes del río Jachal, provincia de San Juan / Lower Paleozoic structure in the headwaters of Río Jachal, San Juan Province

Full Text Available Se describen e interpretan las estructuras desarrolladas en unidades ordovícicas, (Formaciones Yerba Loca y Los Sombreros) y paleógenas-neógenas (Formaciones Vallecito y Rodeo) aflorantes en la quebrada del río Jáchal entre el embalse Cuesta del Viento y Los Túneles. Las primeras forman las sierras [...] Negra y de los Túneles, limitadas en sus bordes orientales por los sobrecorrimientos de la Tranca y los Blanquitos respectivamente y cubiertas en discordancia angular por la Formación Rodeo en los occidentales. El conjunto exhibe grandes pliegues asimétricos, de longitud de onda comparable con el ancho de las sierras, afectados por estructuras de escala hectométrica a métrica, más frecuentes en los limbos orientales, que son también los más tendidos. La orientación general de los ejes de los pliegues es variable desde Az 315 a Az 360, y la vergencia general de las estructuras pre-carboníferas y terciarias es hacia el este, lo que hace imposible el uso de su orientación para diferenciar su edad. La comparación de esta zona con los afloramientos de unidades coetáneas en las nacientes del río San Juan arroja semejanzas sedimentológicas y estructurales, pero también diferencias importantes. Entre las primeras se señalan las identidades litológicas y la presencia de unidades plegadas con ejes N-S sobre el sector oriental de los afloramientos y orientaciones al N-NO en el sector occidental. Entre las diferencias más importantes debe mencionarse la ausencia, en el área de Rodeo, de unidades silúricas equivalentes a la Formación Calingasta y de los conglomerados y ritmitas de la Formación El Planchón, aflorantes en el área del río San Juan. Abstract in english Structures cropping out in the Jachal Valley from the Cuesta del Viento dam to the locality of Los Tuneles are described and analyzed.

The oldest units form the he [...] ights, Sierra Negra de Rodeo and Sierra de los Túneles, which are limited in their eastern flanks by the La Tranca and Los Blanquitos overthrusts, and by the angular unconformity underlying Rodeo Formation in their western ones. The regional folds show asymmetrical shapes and a wavelength comparable to the width of the Sierras, but minor structures ranging from meters to tens of meters are very common in their eastern limbs. Regional folds axis trend varies from Az 315 to Az 360 and the vergence of pre-carboniferous and andean structures point to the east, what makes very difficult to use orientation as a criterion to discriminate the differentiated deformational episodes. The comparison of sedimentological and structural features in the Rodeo area with those at the San Juan River evidences strong similarities but also important differences. Among the first ones, it can be mentioned the lithological and structural resemblance of the Ordovician units, which show NS trending axis in the eastern outcrops and point N-NW in the western ones. Main differences are the absence -in the Rodeo area- of the metapelites of the Silurian Calingasta Formation. and that of the conglomerates and rhythmites of the Devonian (?) El Planchón Formation. present in the San Juan River section.

LA CAÍDA DE UNA ARTESANÍA: CESTERÍA EN SAN JUAN GUELAVIA, OAXACA THE COLLAPSE OF A CRAFT: BASKETMAKING IN SAN JUAN GUELAVIA, OAXACA  

Directory of Open Access Journals (Sweden)

Full Text Available Los artesanos oaxaqueños son célebres por la calidad de sus trabajos, el éxito de sus negocios y la capacidad de sus productos para trascender en el espacio y el tiempo. Los tejedores de algodón y textiles de lana, los fabricantes de cerámica de barro y más recientemente talladores de madera, que hacen alebrijes (animales de madera pintada, producen artículos que son comprados y vendidos en el mercado internacional y son exhibidos mundialmente en las colecciones de museos. Sin embargo, hay artesanías en Oaxaca que no son viables en el mercado y no aparecen en colecciones internacionales. En este documento examinamos la producción de canastas en la comunidad de San Juan Guelavia. Argumentamos que la caída en el mercado refleja tres cambios críticos: primero, una disminución en el uso local; segundo, un alza en los costos de producción; y tercero, una falta de apoyo de exportadores y una incapacidad para involucrarse en el mercado de exportación.Oaxacan artisans are celebrated for the quality of their work, their business success, and the ability of their goods to transcend space and time. Weavers of cotton and woolen textiles, potters, and most recently wood carvers who make alebrijes (painted wooden animals produce goods that are bought and sold on the international market and appear in museum collections world-wide. Nevertheless, there are crafts in Oaxaca that are not viable in the current market and that do not show up in international collections. In this paper, we examine one such craft: basket making in the community of San Juan Guelavia. We argue that the decline in the market for these goods reflects several changes: first, a decline in local use; second, a rise in the costs of production; and third, a lack of support by exporters and an inability to engage the export or tourist markets. In response, local producers have moved into wage labor (locally and through migration to secure their incomes.

Occurrence of Hepatitis C Virus infection in type 2 diabetic patients attending Plateau state specialist hospital Jos Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Abstract Background Glucose intolerance is observed more in patients with HCV infection compared with control subjects with liver disease, Initial studies suggested that Hepatitis C virus infection may be an additional risk factor for the development of diabetes mellitus. This study was therefore carried out to determine the correlation of HCV infection and diabetes. Methods Three hundred (300 confirmed type 2 diabetic patients were screened for hepatitis C virus antibodies at the Plateau state specialist hospital, Jos, using Grand diagnostic test strip. Questionnaire comprising of age, sex, family history on diabetes, duration of disease and marital status were issued to subjects. Results Overall result showed that the prevalence rate of HCV infection was 33(11%. In response to diabetic status, females subjects had a higher prevalence of 178(59.3% compared to males 122(40.7%. Those aged 47–57 recorded the highest seroprevalence 10(30.3% to the Hepatitis C Virus, while Patients without family history of diabetes showed a higher seroprevalence of 13(39.4%. Subjects who never had any blood transfusion recorded a prevalence rate of 6(18.2%. Marital status showed no significant difference [(P = 0.275; P.0.05]. Considering duration of developing diabetes, patients within the range of 1–10 years diabetic status recorded the highest prevalence rate 25(75.8% compared to other ranges considered. Conclusion This study hence, suggests a relatively strong association between HCV infection and diabetes, this therefore call for an urgent approach strategy in the control and management of this disease of the endocrine system.

Prevalence of Escherichia coli among uropathogens in asymptomatic bacteriuria in a Nigerian Tertiary school in Jos, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: This study was carried out to determine the prevalence of Escherichia coli in asymptomatic bacteriuria among the students of Federal School of Medical Laboratory Technology, Jos.Methods: Mid-stream urine samples from 213 students who consented were collected, cultured, isolates identified and antibiotic susceptibility test was carried out according to standard microbiological protocols.Results: Of the 213 test samples screened, 9(4.2% had asymptomatic bacteriuria. The study indicates that 9(4.2% of the samples showed a significant count growth, 4(1.9% had a non significant growth, while 199(93.4% showed no growth. Of the 114 samples screened from female students, 9(7.9% had significant bacteriuria, while of the 99 samples screened from the male counterparts non 0(0.0% had significant bacteriuria. The bacterial isolates recovered in this study were Escherichia coli which had the highest with 6(66.7% while Klebsiella species had the lowest with 3(33.3%.The distribution of microbial isolates recovered from the study shows that Escherichia coli had the highest prevalence of 6(60.0%, followed by Klebsiella species with 3(30.0%, while Candida species had 1(10.0%.The antibiotic susceptibility pattern for the Escherichia coli isolates reveals that all the 6(100% isolates were susceptible to Nalidixic acid, Nitrofurantoin and Gentamycin, while Colistin Phosphate, Tetracycline and Streptomycin had 5(83.3%, 4(66.7% and 1(16.7% respectively. Ampicillin and Cotrimoxazole were resistant to all the Escherichia coli isolates.Conclusion: Asymptomatic bacteriuria was recorded among the females, therefore this call for the need to create more awareness on prevention and control measures for UTIs among females. The antibiogram profile suggested possibilities of drug abuse.

Community-based enterprises and the commons: The case of San Juan Nuevo Parangaricutiro, Mexico  

Directory of Open Access Journals (Sweden)

Full Text Available Commons scholarship has tended to focus on the administration and use of commons by individuals and households and less so on collective enterprises that extract, transform and market what they harvest from the commons. In this paper, we consider Nuevo San Juan, a Mexican case that is well known in the community forestry and commons literature. In San Juan, indigenous community members who hold the rights for the commons are also the members of the enterprise that transforms and markets goods from the commons. We argue that such a strategy is one way to confront internal and external pressures on a commons. We draw upon the transcripts of 40 interviews undertaken during 2006 which are analyzed using a framework developed from the social, community-based and indigenous enterprise literature. Our goal was to utilize this framework to analyze the San Juan Forest Enterprise and understand its emergence and formation as a long-standing community-based enterprise that intersects with a commons, and thereby identify factors that increase chances of success for community enterprises. We found that by starting from the community-based and indigenous enterprise literature and using that literature to engage with thinking on commons, it was possible to consider the enterprise from the perspective of a regulatory framework rather than from the poles of dependency and modernization theories in which much commons work has been based. Enterprise and commons intersect when both are guided by core cultural values and the enterprise can become a new site for the creation of social and cultural cohesion. We also found that there were a number of necessary conditions for commons-based community-enterprises to retain internal and external legitimacy, namely: (1 leadership representative of the broad social mission rooted in the customary institutions, values and norms of the community; (2 accountability of enterprise leaders to the memberships they represent; and (3 a close adherence to the political goals of the community as a whole.

The Crownpoint and Churchrock uranium deposits, San Juan Basin, New Mexico: An ISL mining perspective  

International Nuclear Information System (INIS)

The Crownpoint and Churchrock uranium deposits, San Juan Basin, New Mexico are currently being developed by Uranium Resources, Inc. (URI) and its subsidiary Hydro Resources, Inc. (HRI) with an anticipated start-up in 1998. Both deposits will be developed using advanced in situ leach (ISL) mining techniques. URI/HRI currently has about 14,583 t U (37.834 million pounds U3O8) of estimated recoverable reserves at Crownpoint and Churchrock. at a cost less than $39/kg U ($15/lb U3O8). The uranium endowment of the San Juan Basin is the largest of any province in the USA. In March, 1997, a Final Environmental Impact Statement (FEIS) for the Crownpoint and Churchrock sites was completed by the Nuclear Regulatory Commission which recommends the issuance of an operating license. The FEIS is the culmination of a 9 year effort to license and develop the deposits. The Westwater Canyon Member of the Jurassic Morrison Formation is an arkosic, fine to coarse grained sandstone bounded by near basinwide confining clays deposited in a wet alluvial fan environment within the San Juan Basin. The primary, trend-ore deposits are hosted by the Westwater Canyon Member as humate-rich, syngenetic tabular deposits which were subsequently remobilized into roll fronts. Since deposition in the Jurassic, two phases of remobilization have occurred in the basin causing the formation of in situ leach amenable monometallic uranium rolls free of organic debris. Following in situ mining, ground water restoration of the Crownpoint and Churchrock mines is required to provide a water quality consistent with pre-mining baseline conditions. The development of in situ mining offers an environmentally sound and cost-effective method for uranium extraction. URI/HRI anticipates a production of 385-1,156 Tonnes U/year (1-3 million pounds U3O8) from the New Mexico properties. (author)

Colecistectomía abierta versus laparoscópica: experiencia en el Hospital San Juan de Dios  

Scientific Electronic Library Online (English)

Full Text Available SciELO Costa Rica | Language: Spanish Abstract in spanish La cirugía laparoscópica es una técnica mínimamente invasiva de uso cotidiano en el ámbito mundial. Desde hace quince años, la colecistectomía laparoscópica es un procedimiento seguro y muy valioso a disposición del cirujano. Este estudio tiene como fin comparar los resultados de la colecistectomía [...] laparoscópica en el Hospital San Juan de Dios con la técnica de la colecistectomía abierta ó tradicional. Métodos: Se realizó un estudio retrospectivo de todos los pacientes colecistectomizados desde julio de 1996 a junio de 1999, en el Hospital San Juan de Dios en Costa Rica. Al comparar las dos técnicas quirúrgicas (clásica y laparoscópica), se consideró la evolución posoperatoria y las posibles complicaciones que aparecen posteriores al acto quirúrgico. Además se buscaron las contraindicaciones que dicha técnica pudiese tener. Resultados : Fueron revisados un total de 3193 pacientes colecistectomizados, de los cuales 476 fueron operados por laparoscopia. Se tuvo en éstas menos complicaciones posquirúrgicas y menor estancia posoperatoria que en las colecistectomías abiertas. También se notó una disminución paulatina del tiempo quirúrgico en los actos por laparoscopia. Conclusión: Se comprueban las ventajas de la cirugía invasiva mínima y se documenta que este tipo de abordaje es más seguro y beneficioso para el paciente y para el médico mismo. Abstract in english Justification: Today, laparoscopic surgery as a least invasive technique is widely used in the world. Laparoscopic cholecystectomy is a valuable and safe technique and is has been available to the general surgeon for the last 15 years. In Costa Rica it has become a pretty common procedure with great [...] results but they have not been well studied and documented. This study aims to expose part of the work that takes place at the Hospital San Juan de Dios with laparoscopic cholecystectomy and highlights the results in contrast with those of traditional cholecystectomy. Methodology: Aretrospective study was conducted of all the cholecystectomies performed at the Hospital San Juan de Dios in Costa Rica from July 1996 to June 1999. A comparative analysis between the classic and the laparoscopic approach was completed considering post-operative evolution and postoperative complications. Results: A total of 3193 cholecystectomies, were reviewed, 476 were laparoscopic cholecystectomies, they had less post-operative complications and less post-operative recovery time as opposed to the open cholecystectomies. The study showed further a progressive diminution of the operative time in the laparoscopic group. Conclusions : Laparoscopic cholecystectomy is a safe procedure and it carries several advantages both for thepatient and the surgeon.

Colecistectomía abierta versus laparoscópica: experiencia en el Hospital San Juan de Dios  

Directory of Open Access Journals (Sweden)

Full Text Available La cirugía laparoscópica es una técnica mínimamente invasiva de uso cotidiano en el ámbito mundial. Desde hace quince años, la colecistectomía laparoscópica es un procedimiento seguro y muy valioso a disposición del cirujano. Este estudio tiene como fin comparar los resultados de la colecistectomía laparoscópica en el Hospital San Juan de Dios con la técnica de la colecistectomía abierta ó tradicional. Métodos: Se realizó un estudio retrospectivo de todos los pacientes colecistectomizados desde julio de 1996 a junio de 1999, en el Hospital San Juan de Dios en Costa Rica. Al comparar las dos técnicas quirúrgicas (clásica y laparoscópica, se consideró la evolución posoperatoria y las posibles complicaciones que aparecen posteriores al acto quirúrgico. Además se buscaron las contraindicaciones que dicha técnica pudiese tener. Resultados : Fueron revisados un total de 3193 pacientes colecistectomizados, de los cuales 476 fueron operados por laparoscopia. Se tuvo en éstas menos complicaciones posquirúrgicas y menor estancia posoperatoria que en las colecistectomías abiertas. También se notó una disminución paulatina del tiempo quirúrgico en los actos por laparoscopia. Conclusión: Se comprueban las ventajas de la cirugía invasiva mínima y se documenta que este tipo de abordaje es más seguro y beneficioso para el paciente y para el médico mismo.Justification: Today, laparoscopic surgery as a least invasive technique is widely used in the world. Laparoscopic cholecystectomy is a valuable and safe technique and is has been available to the general surgeon for the last 15 years.

Geochemical variability of natural soils and reclaimed minespoil soils in the San Juan Basin, New Mexico  

Science.gov (United States)

An inventory of total-and extractable-element concentrations in soils was made for three areas of the San Juan Basin in New Mexico: (1) the broad area likely to be affected by energy-related development. (2) an area of soils considered to have potential for use as topsoil in mined-land reclamation. and (3) an area of the San Juan coal mine that has been regraded. topsoiled, and revegetated. Maps made of concentrations of 16 elements in area 1 soils show no gradational pattern across the region. Further. these maps do not correspond to those showing geology or soil types. Sodic or saline problems, and a possible but unproven deficiency of zinc available to plants. may make some of the soils in this area undesirable for use as topsoil in mined-land reclamation. Taxonomic great groups of soil in this area cannot be distinguished because each great group tends to have a large within-group variability if compared to the between-group variability. In area 2 the major soils sampled were of the Sheppard. Shiprock. and Doak association. These soils are quite uniform in chemical composition and are not greatly saline or sodic. As in area 1 soils. zinc deficiency may cause a problem in revegetating most of these soils. It is difficult to distinguish soil taxonomic families by using their respective chemical compositions. because of small between-family variability. Topsoil from a reclaimed area of the San Juan mine (area 3) most closely resembles the chemical composition of natural C horizons of soil from area 1. Spoil material that has not been topsoiled is likely to cause sodic-and saline-related problems in revegetation and may cause boron toxicity in plants. Topsoiling has apparently ameliorated these potential problems for plant growth on mine spoil. Total and extractable concentrations for elements and other parameters for each area of the San Juan Basin provide background information for the evaluation of the chemical quality of soils in each area.

Full Text Available El artículo estudia las estrategias ideológico-discursivas desplegadas por Juan María Gutiérrez en su ensayo sobre la vida y obra de sor Juana Inés de la Cruz. Se analiza la lectura que hace un crítico decimonónico de la más grande poeta novohispana, un defensor del credo independentista (y, por lo mismo, profundamente antihispánico de una escritora colonial. En última instancia, lo que se pretende dilucidar es cómo el romanticismo rioplatense asume la conflictiva herencia del virreinato y cómo el ensayo de Gutiérrez se inscribe en el debate en torno a la incorporación de América en el concierto de la cultura occidental.

PRELIMINARY GEOID MODEL IN SAN JUAN PROVINCE: A CASE STUDY IN THE ANDES  

DEFF Research Database (Denmark)

A high-resolution and high-precision detailed gravimetric geoid has been computed for San Juan province in Argentina, ranging from 27 degrees S to 34 degrees S in latitude and 72 degrees W to 65 degrees W in longitude. The gravimetric geoid was calculated using the RTM method, a multiband spherical Stokes Fast Fourier Transformation, and the removerestore technique for the spherical harmonic reference field and the terrain. As an external evaluation, the gravimetric quasigeoid/geoid was compared to the geoid heights obtained from 90 GPS/levelling points available for the province. Finally, a GPS-tailored local geoid, which fits the GPS observations, was computed.

Pyroclastic eruptions from Axial caldera, Juan de Fuca Ridge, NE Pacific Ocean  

International Nuclear Information System (INIS)

Unconsolidated volcaniclastic glass deposits on the flanks of Axial Seamount, a caldera system situated on the Juan de Fuca Ridge in the NE Pacific Ocean, demonstrate the occurrence of explosive events, in addition to effusive activity. The variety of produced glass fragments ranges from various angular forms to thin deep-sea limu o Pele, with dominantly moderately fractionated to occasionally primitive MOR basalt composition. A model involving the collapse of a magmatic foam layer may account for the observed spectrum of glass fragments.

Regional Studies Program. Biological aspects of surface coal mine reclamation, Black Mesa and San Juan Basin  

Energy Technology Data Exchange (ETDEWEB)

This report discusses case study data on surface mine reclamation accumulated at selected mines in the Southwest, specifically the Black Mesa Mine in Arizona and the Navajo Mine located south of Fruitland, New Mexico, in the San Juan Basin. Experimental results have made it apparent that reclamation of disturbed lands cannot begin and end with planting seed. The report therefore considers hydrologic, edaphic, and biotic factors, as well as land use and management, as important aspects of land reclamation. Recommendations are made to initiate, broaden, and intensify research studies in plant succession, productivity, species selection, and attendant soil characteristics, along with grazing practices and land use potential.

Ilustración y liberalismo en la obra de Juan Sempere y Guarinos (1754-1830  

Directory of Open Access Journals (Sweden)

Full Text Available RESUMEN: Juan Sempere y Guarinos fue un miembro notable del elenco ilustrado español. Su ideario es el resultado de la confluencia de diversas corrientes modernizadoras: el humanismo y el arbitrismo españoles, la Ilustración italiana, la Ilustración francesa y la Ilustración inglesa. Su interés por la historia legal e institucional de España y no menos por el liberalismo económico, filtrados por un regalismo a ultranza y una sólida creencia en la bondad política del Estado centralista encarnado en la monarquía borbónica, hacen de él un representante típico del pensamiento de crisis y transición, en este caso, el que une, no sin contradicciones, la Ilustración con el primer Liberalismo moderado o conservador.ABSTRACT: Juan Sempere y Guarinos was an outstanding member of the elite of the Spanish Enlightenment. His ideas were the outcome of the mingling of various modernist-oriented crosscurrents: Spanish humanism and «arbitrismo» and the Italian, French and English Enlightenments. Given his interest in Spanish legal and institutional history, as well as in economic liberalism, as shaped by his unconditional «regalismo» and his solid belief in the political virtues of the centralized state embobied in the Bourbon monarchy, he is a typical representative of the thinking thrown up by periods of crisis and transition. In his particular case this involves the somewhat strained merging of Enlightenment thought with early moderate and conservative Liberalism.

Didn’t it matter to him absolutely?: Juan Vilanova and the controversy about tertiary Man  

Directory of Open Access Journals (Sweden)

Full Text Available During the founding period of palaeoanthropology, the postulate about tertiary age of humankind was an outstanding subject. First proposals were based on supposed proofs about ancient lithical industry (eoliths. Some discoveries of human fossil remains complicated that issue, because they were dated as pliocene or oldest. This controversy about so-called «tertiary man» soon arrived to Spain. Juan Vilanova y Piera, palaeontologist and professor at Madrid, dealt with it from an antievolutionist point of view. When a human fossil skeleton, included in the Botet’s collection, with several apparently primitive traits arrived to Valencia from Argentina, Vilanova got reasserted and exposed his ideas about this question more intensely.

Un tema relevante durante el período fundacional de la paleoantropología fue el postulado de la antigüedad terciaria de la humanidad. Las primeras propuestas se basaban en supuestas evidencias de industria lítica (eolitos. La cuestión se complicó con el descubrimiento de diversos fósiles humanos que fueron datados como pliocenos o incluso de mayor antigüedad. Esta polémica sobre el llamado «hombre terciario» llegó pronto a España. El paleontólogo y catedrático de la Universidad Central, Juan Vilanova y Piera, se ocupó extensamente del asunto desde perspectivas antievolucionistas. La llegada a Valencia en 1889, formando parte de la colección paleontológica donada por José Rodrigo Botet, de un esqueleto humano fósil procedente de Argentina que mostraba rasgos aparentes de primitivismo, llevó a Vilanova a reafirmarse y exponer más intensamente sus ideas sobre esta cuestión.

Directory of Open Access Journals (Sweden)

Full Text Available Juan Solórzano Pereira was outstanding in 17th century Spain both for his vast erudition in Philosophy, Theology and Law and for his thorough knowledge of legislation concerning the American colonies. It was quite natural for Philip III to send him to Peru as Oidor of the Lima Tribunal and give him the mandate to compile and publish the materials dealing with the most fundamental problems of colonial legislation. He did so in three steps: 1.The question of justifying the Spanish takeover. 2. The rightfulness of continuing the Spanish presence in those territories. 3. The critical appraisal of the Spanish Administration and Government in the area.La inmensa erudición jurídica, filosófica y teológica de Juan Solórzano Pereira y el exhaustivo conocimiento de la legislación de Indias hacen de él una figura de primera magnitud en el campo del derecho indiano en el siglo XVII. Ello explica el mandato real que Felipe III le impuso, al ser enviado al Virreinato de Perú como Oidor de la Audiencia de Lima, de recoger y publicar las cuestiones fundamentales referentes al derecho indiano, que redujo a tres: 1. Justicia de la ocupación de las Indias por los españoles; 2. Justicia de la permanencia española en las Indias; 3. Justicia de la Administración y Gobernación españolas en las Indias.

Dinosaur Footprints in Lower Cretaceous Beds in San Juan Raya, Southern Mexico and the Paleoenvironmental Implications  

Science.gov (United States)

Dinosaur footprints were traced at San Juan Raya, an important site in Mexico, a world fossil site. This site is found at South-west of the State of Puebla, within the Biosphere Reserve of Tehuacan-Cuitcatlán, to the southwest of the Tehuacan valley. These footprints were recorded by tracing them on transparent paper at Barranca Agua Nueva, at point 18°18.56´N 97°37´W. Using Jacob´s staff a stratigraphic register was generated from 50 m ascending and descending in stratigraphically direction from the bed where footprints were founded. Bivalbes, nerineas, shell fragments, and trigonias were founded in this sequence as well as cross bedding of clays and fine grain sand, some which display ripples. Fifty two footprints were recorded and five different tracks identified, observing two different sizes. The tracks of dinosaur footprints present the common Teropode ichnites. The succession where dinosaur footprints have been found, are interpreted as a peritidal environment. This investigation contributes to an eco-tourism project of San Juan Raya.

Evolution of the western segment of Juan Fernández Ridge (Nazca Plate): plume vs. plate tectonic processes  

Science.gov (United States)

The Juan Fernandez Ridge (Eastern Pacific, Nazca Plate) is thought to be a classic hot spot trail because of the apparent age progression observed in 40Ar-39Ar data. However, geological evidence and some thermochronological data suggest a more complex pattern with a rejuvenation stage in Robinson Crusoe Island, the most eroded of the Juan Fernandez Archipelago. In fact, a postshield stage at 900-700 ka separates the underlying shield-related pile from the post-erosional alkaline succession (Ba/Yb=38.15; La/Yb=15.66; Ba/Y=20.27; Ba/Zr=2.31). Shield volcanoes grew at high effusion rate at ca. 5-4 Ma erupting mostly tholeiitic to transitional magmas (Ba/Yb=18.07-8.32; La/Yb=4.59-9.84; Ba/Y=4.24-8.18; Ba/Zr=0.73-1.09). Taken together, shield volcanoes form a continuous plateau with a base at ca. 3900 mbsl. However, a more complex structural pattern can be inferred from geophysical data, which suggest some intracrustal magma storage and a more extended area of magma ascent. A role for the Challenger Fracture Zone is hypothesized fueling the controversy between pristine plume origin and the effect of plate tectonic processes in the origin of intraplate volcanism. This research is supported by FONDECYT Project 1110966.

A tidal model for eastern Juan de Fuca Strait and the southern Strait of Georgia  

Science.gov (United States)

A three-dimensional, barotropic, finite element model is used to calculate the tidal flows in eastern Juan de Fuca Strait and the southern Strait of Georgia. The harmonics of eight constituents are computed and compared with those from previous finite difference models and those from historical tide gauge and current meter observations. Root-mean-square differences between observed and calculated sea level amplitudes are within 2.0 cm for all constituents, and the phases are within 4.0° for all constituents except K2. Horizontal currents from the model are found to reproduce the observed vertical variations in shear except in regions where stratification effects and internal tides exist. In particular, the model representation of currents at six stations in the Canadian Tide and Current Tables (volume 5) is accurate. The pattern of tidal residual currents has much more detail than previous, coarser resolution models, and numerous eddies are predicted. Computed energy flux fields reveal that over a 29-day period only 38% of the tidal power entering Juan de Fuca Strait is transmitted into the southern Strait of Georgia, and of the 39% entering Haro Strait, 36% is dissipated within the strait itself.

Creep Transients and Fault Interaction from Repeating Earthquakes Near San Juan Bautista, California  

Science.gov (United States)

Along creeping sections of the San Andreas and other faults, small asperities in the fault zone load and fail in characteristic repeating earthquake sequences which can be used as subsurface creepmeters. Here, we use these virtual creepmeters to examine and compare slip rates on both the northwestern end of the creeping section of the San Andreas Fault near San Juan Bautista and on the nearby sub-parallel Sargent Fault, previously observed to have ~3mm/year of right-lateral creep. While creep on the San Andreas increases dramatically in response to the 1989 Loma Prieta earthquake and takes about ten years to resume interseismic rates, the Sargent shows little immediate response. The Sargent rather exhibits a very gradual increase of activity after the Loma Prieta earthquake, consistent with its generally lower interseismic slip rate and with static stress change models that show only a minor increase in the stress along the Sargent. When the SAF resumes its interseismic rate, it begins creeping coherently in time with the Sargent, indicating a mutual driving force in the system. Background seismicity in gray points, newly discovered repeaters in black circles (inset). Boxes show study area. Stars show epicenters of 1989 Loma Prieta EQ, 1998 San Juan Bautista EQ, and 2004 Parkfield EQ.

Arsenic contamination of natural waters in San Juan and La Pampa, Argentina.  

Science.gov (United States)

Arsenic (As) speciation in surface and groundwater from two provinces in Argentina (San Juan and La Pampa) was investigated using solid phase extraction (SPE) cartridge methodology with comparison to total arsenic concentrations. A third province, Río Negro, was used as a control to the study. Strong cation exchange (SCX) and strong anion exchange (SAX) cartridges were utilised in series for the separation and preservation of arsenite (As(III)), arsenate (As(V)), monomethylarsonic acid (MA(V)) and dimethylarsinic acid (DMA(V)). Samples were collected from a range of water outlets (rivers/streams, wells, untreated domestic taps, well water treatment works) to assess the relationship between total arsenic and arsenic species, water type and water parameters (pH, conductivity and total dissolved solids, TDS). Analysis of the waters for arsenic (total and species) was performed by inductively coupled plasma mass spectrometry (ICP-MS) in collision cell mode. Total arsenic concentrations in the surface and groundwater from Encon and the San José de Jáchal region of San Juan (north-west Argentina within the Cuyo region) ranged from 9 to 357 ?g l(-1) As. Groundwater from Eduardo Castex (EC) and Ingeniero Luiggi (LU) in La Pampa (central Argentina within the Chaco-Pampean Plain) ranged from 3 to 1326 ?g l(-1) As. The pH range for the provinces of San Juan (7.2-9.7) and La Pampa (7.0-9.9) are in agreement with other published literature. The highest total arsenic concentrations were found in La Pampa well waters (both rural farms and pre-treated urban sources), particularly where there was high pH (typically > 8.2), conductivity (>2,600 ?S cm(-1)) and TDS (>1,400 mg l(-1)). Reverse osmosis (RO) treatment of well waters in La Pampa for domestic drinking water in EC and LU significantly reduced total arsenic concentrations from a range of 216-224 ?g l(-1) As to 0.3-0.8 ?g l(-1) As. Arsenic species for both provinces were predominantly As(III) and As(V). As(III) and As(V) concentrations in San Juan ranged from 4-138 ?g l(-1) to region) and 23-346 ?g l(-1) and 0.04-76 ?g l(-1) for groundwater, respectively. This translates to a relative As(III) abundance of 69-100% of the total arsenic in surface waters and 32-100% in groundwater. This is unexpected because it is typically thought that in oxidising conditions (surface waters), the dominant arsenic species is As(V). However, data from the SPE methodology suggests that As(III) is the prevalent species in San Juan, indicating a greater influence from reductive processes. La Pampa groundwater had As(III) and As(V) concentrations of 5-1,332 ?g l(-1) and 0.09-592 ?g l(-1) for EC and 32-242 ?g l(-1) and 30-277 ?g l(-1) As for LU, respectively. Detectable levels of MA(V) were reported in both provinces up to a concentration of 79 ?g l(-1) (equating to up to 33% of the total arsenic). Previously published literature has focused primarily on the inorganic arsenic species, however this study highlights the potentially significant concentrations of organoarsenicals present in natural waters. The potential for separating and preserving individual arsenic species in the field to avoid transformation during transport to the laboratory, enabling an accurate assessment of in situ arsenic speciation in water supplies is discussed.

Sedimentología y evolución del campo de dunas de Médanos Grandes (provincia de San Juan, Argentina) / Sedimentology and evolution of Médanos Grandes dunefield (San Juan province, Argentina)  

Scientific Electronic Library Online (English)

Full Text Available SciELO Argentina | Language: Spanish Abstract in spanish El campo eólico de Médanos Grandes, sudeste de la provincia de San Juan (Argentina), es uno de los más extensos del país y está formado por distintos tipos de dunas, principalmente transversales y longitudinales. Junto a éstas aparecen grandes megaformas eólicas o draas, de hasta 70 metros de altura [...] y 2000 metros de espaciamiento. El análisis de imágenes satelitales permitió identificar cinco unidades geomorfológicas caracterizadas por geoformas de diferente morfología, tamaño, orientación y dirección de migración. En la unidad geomórfica 1 (UG1) se incluyen draas de crestas transversales (orientadas al azimut 150º), ligeramente sinuosas, con dunas menores sobreimpuestas. La disposición de sus caras de sotavento indica que este conjunto se desarrolló a partir de paleovientos del sudoeste. En la conformación de la UG2 aparecen también draas transversales con dunas asociadas, sin embargo en este caso la orientación de los primeros evidencia paleovientos del noreste. Por otro lado, las dunas menores se disponen de forma oblicua y se habrían, por lo tanto, formado con posterioridad. En la UG3, ubicada en el centro del campo eólico, se destaca la presencia de grandes hoyos de deflación, de hasta 1000 metros de diámetro y 50 metros de desnivel con respecto a las dunas adyacentes. Así mismo, esta unidad se caracteriza por un diseño enrejado de médanos, resultado de la interferencia de las crestas de los draas pertenecientes a las unidades 1 y 2. La UG4 comprende dunas longitudinales, de hasta 40 metros de altura y 150 metros de espaciamiento, que se asocian a pequeñas dunas transversales. La disposición de las dunas longitudinales, junto con la orientación de las caras de sotavento de las formas menores, indican paleovientos del sud-sudeste. Por último, la UG5 está integrada por dunas transversales, barjanoides y longitudinales, que ocupan la periferia del campo eólico aquí estudiado. Constituye la unidad más moderna y respondería también a vientos del sud-sudeste similares a los actuales. Las geoformas eólicas de Médanos Grandes están formadas por arenas finas (X= 2,88 ø), muy bien seleccionadas (s= 0,45 ø) y con distribuciones granulométricas unimodales y simétricas (SK 1 = 0,05). El percentil del 1 % corresponde a la arena mediana (1,87 ø) y el material inferior a 53 ? conforma en promedio el 1,05 % de las muestras. En cuanto a la composición de las arenas predominan los fragmentos líticos (clastos de volcanitas, mayormente ácidas y mesosilícicas, esquistos micáceos, anfibolitas, milonitas, chert, sedimentitas y calizas), junto a moderados porcentajes de feldespatos y muy baja proporción de cuarzo y minerales pesados. La presencia de geoformas con diferente morfología y orientación indica que el sistema eólico de Médanos Grandes es policíclico ya que en su conformación se sucedieron distintos episodios de crecimiento, bajo distintos patrones de vientos. Las unidades geomórficas identificadas pueden ser tentativamente correlacionadas con los estadios climáticos propuestos por autores anteriores para la región pampeana. Finalmente, en la actualidad el campo eólico de Médanos Grandes se halla parcialmente erodado debido a la acción fluvial, constituyendo probablemente un remanente de un extenso sistema eólico que cubría gran parte del valle del Bermejo.

Sin embargo, hay artesanías en Oaxaca que no son viables en el mercado y no aparecen en colecciones internacionales. En este documento examinamos la producción de canastas en la comunidad de San Juan Guelavia. Argumentamos que la caída en el mercado refleja tres cambios críticos: primero, una disminución en el uso local; segundo, un alza en los costos de producción; y tercero, una falta de apoyo de exportadores y una incapacidad para involucrarse en el mercado de exportación. Abstract in english Oaxacan artisans are celebrated for the quality of their work, their business success, and the ability of their goods to transcend space and time. Weavers of cotton and woolen textiles, potters, and most recently wood carvers who make alebrijes (painted wooden animals) produce goods that are bought [...] and sold on the international market and appear in museum collections world-wide. Nevertheless, there are crafts in Oaxaca that are not viable in the current market and that do not show up in international collections. In this paper, we examine one such craft: basket making in the community of San Juan Guelavia. We argue that the decline in the market for these goods reflects several changes: first, a decline in local use; second, a rise in the costs of production; and third, a lack of support by exporters and an inability to engage the export or tourist markets. In response, local producers have moved into wage labor (locally and through migration) to secure their incomes.

Directory of Open Access Journals (Sweden)

Full Text Available El interés por rescatar la figura de Juan Bautista Iguíniz Vizcaíno como promotor de los estudios bibliotecológicos en México resulta de especial relevancia para el análisis de la trayectoria de las bibliotecas mexicanas en el siglo XX. Su actividad profesional abarca un vasto periodo durante el cual se le puede encontrar en todas las vertientes del quehacer que rodea a las bibliotecas: en el funcionamiento de éstas; en la integración de acervos y bibliografías; en el diseño de planes de estudio de escuelas de bibliotecarios; en la constitución de asociaciones de especialistas que generaron vínculos en el país y en el extranjero y, finalmente, en la más importante para él, la práctica docente, que constituyó la pasión de su vida. El presente proyecto de investigación abarca un largo periodo histórico en la vida de nuestro país (1915-1945, por ello nuestro personaje y su obra formarán parte inherente del mismo. Un ejercicio profesional tan rico y prolongado lleva necesariamente a ligar muchas acciones en la descripción que ahora presentamos. Los actores serán la Biblioteca Nacional, la Universidad, Nacional primero y Autónoma después, y la Secretaría de Educación Pública, y algunos otros.This research project looks at a period spanning from 1915 to 1945 and focuses on a reexamination of the life and work of Juan Bautista Iguíñiz Vizcaíno, an early promoter of Library Science in Mexico, whose legacy is singularly relevant to any analysis of the development of Mexican libraries in the twentieth century. His professional activity carried out over a broad period finds him intimately connected to a vast array of library tasks, including operational management, integration of collections and acquisitions; curriculum design for school librarians and the founding of professional associations of Library Science specialists here and abroad. He was passionately devoted to teaching, which he considered his foremost vocation. The study of this rich epoch necessarily entails gathering a broad variety of material. The main actors in this story are the National Library, The National University and subsequent UNAM, and the Ministry of Education.

Con el objetivo de identificar los aspectos clínicos epidemiológicos que caracterizan a la cardiopatía isquémica en 150 pacientes de 15 años y más, pertenecientes a tres consultorios médicos del Consejo Popular "Galope, San Juan y Martínez", en el periodo comprendido enero _ julio del año 2009, y por ser este el de mayor incidencia y prevalencia en el municipio se realizó una investigación descriptiva y transversal, que incluyó el interrogatorio, examen físico y electrocardiograma a la totalidad de la muestra, procesándose los datos a través del valor porcentual y Ji cuadrado en los casos necesarios. Se encontró un mayor número de hombres que mujeres en la muestra estudiada. En ambos grupos predominaron las edades superiores a 56 años. La cardiopatía isquémica sin angina fue la forma clínica que prevaleció, mientras que las alteraciones del segmento S-T predominaron entre los hallazgos electrocardiográficos. El hábito de fumar, el sedentarismo y la hipertensión arterial fueron los factores de riesgo más frecuentes en la serie. Los mismos se incrementaron a medida que aumento la edad, y todos predominaron de manera significativa en el grupo con cardiopatía isquémica. Se encontró una relación directamente proporcional entre los factores de riesgo asociados entre sí y la cardiopatía isquémica.Ischemic Heart Disease is a health problem that takes a great number of lives off and it is a cause of disability all over the world. The objective of this research was to identify clinical and epidemiological aspects that characterize ischemic heart disease in 150 patients (15 years or older, belonging to three doctor's offices in the Popular Council of "Galope", San Juan y Martinez, Pinar del Rio during January-July 2009. This place presents the greatest incidence and prevalence in the municipality. A descriptive and cross-sectional research was conducted including questioning, physical examination and electrocardiogram to the total of the sample chosen. Data were processed using percentage value and chi square when necessary. In the sample male sex prevailed over the female, and ages older than 56 in both groups. Ischemic heart disease without angina was the prevailing clinical manifestation; meanwhile alterations of the ST-segment were the most common electrocardiographic findings. Smoking, sedentary life and hypertension were the most frequent risk factors in the series, increasing with age and all of them prevailed in the group suffering from ischemic heart disease significantly. A direct relationship between risk factors associated and ischemic heart disease was found.

TÓPICO HISTORIA Y FICCIÓN: HETEROGENEIDAD LATINOAMERICANA EN UMBRAL DE JUAN EMAR / Topic history-fiction: Latin-American heterogeneity in Umbral of Juan Emar  

Scientific Electronic Library Online (English)

Full Text Available En el apartado Noche 3 de Umbral, Juan Emar se vale de la estrategia de la hibridez genérica al construir una novela-drama que resignifica aportes de la vanguardia metaficcional. Nuestra hipótesis es que mediante la “refuncionalización paródica” (Hutcheon) de la diferencia conceptual entre historia [...] y ficción se despliega una poética vanguardista que acoge el simultaneísmo temporal y espacial. Se trabaja con el enfoque postestructuralista foucaultiano que distingue entre una Historia Global, el metarrelato moderno y una Historia General; la que estudia las discontinuidades en las series temporales. En efecto, la poética de la simultaneidad es en la narrativa emariana un mecanismo dislocador de una serie de oposiciones binarias de la episteme moderna: obra dramática v/s representación teatral, espacio escénico v/s sala de espectadores, autor v/s obra, pasado v/s futuro, arte v/s vida, entre otros. Emar despliega así en forma magistral una propuesta vanguardista que da cuenta de la heterogeneidad de tradiciones culturales como impronta de escritura de un sujeto latinoamericano. Abstract in english In paragraph Night 3 of his novella Umbral, Juan Emar utilices hybridism as a generic strategy in the construction of a novella-drama that assign new meanings to the contributions of the metafictional Avant Garde. Our hipothesis is that throught a “parodic refunctionalization” of the distinction bet [...] ween history and fiction is conveying an Avant Garde poetics that promote the spatial and temporal simultaneity. We work with the foucaultian postestructuralism focus which make a distinction between Global History; the modern metanarrative and a General History; that studies the discontinuities in temporals series. The simultaneity poetic’s is in their narrative a mechanism that dislodges a series of binary oppositions as: dramatic work vs. theatrical representation, scenic space vs auditorium, author vs. work, past vs. future, art vs. life, among others. Emar deploys in a masterly way, his Avant Garde proposal of the heterogeneity of cultural traditions as writing impronta of a Latin-American subject.

Full Text Available Este trabajo presenta un inventario de procesos de remoción en masa, en las cuencas principales que afectan a las localidades de Colangüil, Malimán, Angualasto y Buena Esperanza, ubicadas en el departamento Iglesia, provincia de San Juan, a partir de la interpretación y análisis digital de fotografías aéreas e imágenes satelitales de diversa resolución. Se analiza en entorno de sistemas de información geográfica (SIG la ocurrencia de los procesos de remoción en masa en relación a varios factores o variables condicionantes (litología, elevación, pendiente, orientación e insolación. En la zona de estudio se reconocieron tres ambientes morfoestructurales principales, la Precordillera Occidental al este, integrada mayormente por sedimentitas paleozoicas, la Cordillera Frontal al oeste, caracterizada por el volcanismo permo-triásico, ambas separadas por el valle de Iglesia que comprende principalmente los afloramientos paleógenos-neógenos. Los resultados indican que de las 760 geoformas identificadas como procesos de remoción en masa el 45,53 % corresponden a flujos y de ellos el 75,43 % son activos, siendo el principal factor desencadenante las fuertes precipitaciones de carácter torrencial.This study shows an inventory of lanslides, starting from the interpretation and digital analysis of aerial photographs and satellite images of varied resolution, in the main basins which affect the localities of Malimán, Angualasto and Buena Esperanza, in the Iglesia Department, San Juan Province. The occurrence of landslides in relation to several determining factors or variables (lithology, elevation, slope, aspect, and insolation is analyzed in GIS environment. Three main morphostructural environments have been recognized in the study area: the Western Precordillera to the western, principally made up of paleozoic sedimentites and the Cordillera Frontal to the east, which is characterized by Permo-Triassic volcanism. Both geological provinces are separated by the Iglesia Valley which comprises mainly the paleogene-neogene outcrops. The results indicate that out of the 760 geoforms identified as landslides, 45,53 % corresponds to flows, and from these 75,43 % are active, being the the main triggering agent, the heavy rains.

Se analiza en entorno de sistemas de información geográfica (SIG) la ocurrencia de los procesos de remoción en masa en relación a varios factores o variables condicionantes (litología, elevación, pendiente, orientación e insolación). En la zona de estudio se reconocieron tres ambientes morfoestructurales principales, la Precordillera Occidental al este, integrada mayormente por sedimentitas paleozoicas, la Cordillera Frontal al oeste, caracterizada por el volcanismo permo-triásico, ambas separadas por el valle de Iglesia que comprende principalmente los afloramientos paleógenos-neógenos. Los resultados indican que de las 760 geoformas identificadas como procesos de remoción en masa el 45,53 % corresponden a flujos y de ellos el 75,43 % son activos, siendo el principal factor desencadenante las fuertes precipitaciones de carácter torrencial. Abstract in english This study shows an inventory of lanslides, starting from the interpretation and digital analysis of aerial photographs and satellite images of varied resolution, in the main basins which affect the localities of Malimán, Angualasto and Buena Esperanza, in the Iglesia Department, San Juan Province. [...] The occurrence of landslides in relation to several determining factors or variables (lithology, elevation, slope, aspect, and insolation) is analyzed in GIS environment. Three main morphostructural environments have been recognized in the study area: the Western Precordillera to the western, principally made up of paleozoic sedimentites and the Cordillera Frontal to the east, which is characterized by Permo-Triassic volcanism. Both geological provinces are separated by the Iglesia Valley which comprises mainly the paleogene-neogene outcrops. The results indicate that out of the 760 geoforms identified as landslides, 45,53 % corresponds to flows, and from these 75,43 % are active, being the the main triggering agent, the heavy rains.

Juan Bruno Zayas Alfonso: médico y general de brigada en la guerra necesaria / Juan Bruno Zayas Alfonso: Doctor and General of Brigade in the necessary war  

Scientific Electronic Library Online (English)

Full Text Available SciELO Cuba | Language: Spanish Abstract in spanish Juan Bruno Zayas Alfonso fue un brillante jefe militar y un excelente médico, que supo combinar ambas tareas de manera ejemplar y devino una de las figuras más importantes de la Guerra de Independencia de Cuba. En el presente artículo se reseñan, de forma historiográfica y documental, aspectos impor [...] tantes de su vida; se señalan sus orígenes familiares, constituidos por comerciantes y aristócratas por parte del padre, y sacarócratas y accionistas ferrocarrileros por parte de la madre, y se destaca que el tránsito de un miembro de esta familia a la posición radical de combatiente revolucionario conformó un hecho social de gran interés en la historiografía cubana. De igual manera, se describen algunos momentos de su infancia, sus estudios -- desde el bachillerato hasta su matrícula en la Facultad de Medicina y Cirugía -- y su labor como médico en diferentes localidades de la antigua provincia de Las Villas, con la puntualización de que debe ser considerado como el primer médico cubano que ejerció la medicina rural. Asimismo, se comenta el alzamiento desde Vega Alta y su meritoria labor en la lucha independentista, que le confirió en solo 14 meses el grado de general de brigada, para ser en esos momentos el brigadier más joven del Ejército Libertador. Finalmente, los autores analizaron diferentes versiones de su caída en combate el 30 de julio de 1895 Abstract in english Juan Bruno Zayas Alfonso was a brilliant military boss and an excellent doctor, who was an example of how to combine both tasks and became one of the most important personalities in the Cuban Independence War. This work compiles, historiographically and documentarily, important aspects of his life, [...] his family origins are pointed out, constituted by merchants and aristocrats on the part of the father, and sacarocrats and shareholders railwaymen on the part of the mother; and the evolution of a member of this family to revolutionary combatant's radical position conformed a social fact of great interest in the Cuban historiography. In a same way, some moments of his childhood are described, his studies -- from the high school to his registration in the Medicine and Surgery Faculty -- and his work as doctor in different towns of the old county of Las Villas, pointing out that he should be considered as the first Cuban doctor who exercised the rural medicine. Also, the raising from Vega Alta is commented and his meritorious work in the independentist fight, which conferred him in only 14 months the grade of general of brigade, to become in those moments the youngest brigadier in the Liberator Army. Finally, the authors analyzed different versions of his death in combat July 30th, 1895

A new translational repression element and unusual transcriptional control regulate expression of don juan during Drosophila spermatogenesis.  

Science.gov (United States)

The Drosophila don juan (dj) gene encodes a basic protein that is expressed solely in the male germline and shows structural similarities to the linker histone H1. Don Juan is located in two different subcellular structures: in the nucleus during the phase of chromatin condensation and later in the mitochondrial derivatives starting with spermatid individualization. The don juan gene is transcribed in primary spermatocytes under the control of 23 bp upstream in combination with downstream sequences. During meiotic stages and in early spermatid stages don juan mRNA is translationally repressed for several days. Analysis of male sterile mutants which fail to undergo meiosis shows that release of dj mRNA from translational repression is independent of meiosis. In gel retardation assays 60 nucleotides at the end of the dj leader form four major complexes with proteins that were extracted from testes but not with protein extracts from ovaries. Transformation studies prove that in vivo 35 bp within that region of the dj mRNA is essential to confer translational repression. UV cross-linking studies show that a 62 kDa protein specifically binds to the same region within the 5' untranslated region. The dj translational repression element, TRE, is distinct from the translational control element, TCE, described earlier for all members of the Mst(3)CGP gene family. Moreover, expression studies in several male sterile mutants reveal that don juan mRNA is translated in earlier developmental stages during sperm morphogenesis than the Mst(3)CGP mRNAs. This proves that translational activation of dormant mRNAs in spermatogenesis occurs at different time-points which are characteristic for each gene, an essential feature for coordinated sperm morphogenesis.

La Casa de don Juan de Austria en el gobierno de la Monarquía de Felipe IV  

Directory of Open Access Journals (Sweden)

Full Text Available La forma en que se había configurado la Monarquía Hispánica durante los reinados de Carlos V y Felipe II quebró durante la segunda mitad del reinado de Felipe IV, por lo que se hizo necesaria la búsqueda de nuevas fórmulas para que la constitución de la Monarquía volviera a ser viable. El reconocimiento de don Juan de Austria, por parte de Felipe IV, se enmarca en éste proceso mediante el intento de recomposición de las relaciones de la corte de Madrid con los territorios periféricos de la Monarquía, por lo que la trayectoria política de don Juan durante los primeros años estuvo vinculada a la coyuntura y evolución global de la Monarquía. Así lo demuestra su periplo: Portugal, Flandes, gobierno de la Armada marítima para la recuperación de los presidios toscanos y, finalmente, Nápoles. Para llevar a cabo todas esas empresas políticas, Felipe IV situó a su alrededor a una serie de asesores y ministros que conformaron sus sucesivos servicios. En estas líneas se va a proceder al estudio de las mismas, con el fin de comprender el papel político desempeñado por don Juan antes de su llegada a Nápoles en la segunda mitad de 1647.The way in which the Spanish Monarchy was organized during Charles V and Philip II reigns, broke up at the second half of Philip IV reign. So, there was necessary to find new alternatives with which the Spanish Monarchy returned to be viable. The recognition of don John of Austria by Philip IV, must be frame in this process, because it tried to recompose the relationships between the court of Madrid and the other European territories of the Monarchy. So, the earliest years of the political career of don John were connected with the political evolution of the whole Monarchy. His different political destinations prove this: Portugal, Flanders, the government of the royal navy to recover the Presidi Toscani and, finally, the reign of Naples. To obtain the success in all these territories, Philip IV situated around him different advisers and ministers whom composed his successives households. In this paper we will analyze them to understand the political role played by don John before his arrival in Naples at the second half of 1647.

Plate tectonic reconstructions of the Juan Fernandez microplate: Transformation from internal shear to rigid rotation  

Science.gov (United States)

Side-scan sonar, swath bathymetry and magnetic anomaly date define a detailed, three-phase history of the Juan Fernandez microplate. The ˜6 m.y. history is presented in a series of discrete time steps to document the growth and reorganization of propagating spreading centers and structural feature, and microplate kinematic evolution. Prior to the microplate, the East Pacific Rise at the Pacific-Antarctic-Nazca triple junction was offset by a long transform fault zone, likely the fastest slipping transform on Earth at anomaly 3A time. The microplate originated from an intratransform setting between anomaly 3A (5.95 Ma) and anomaly 3 (5.24 Ma) time. Its early development resembled a large propagating rift system, and microplate core structures suggest the entire offset zone may have experienced deformation. Fast propagation of the East Ridge dominated microplate growth until ˜2.6-1.9 Ma when seafloor spreading became the dominant growth process. The microplate rotation rate increased threefold (from 9 to 29° m.y.-1 average) from phase 1 (4.2-2.6 Ma) to phase 2 (2.6-1.1 Ma) of the microplate's history, then reduced fourfold (29 to 7° m.y. -1 average; phase 3, 1.1 Ma to Present). Phases 2 and 3 of the microplate's rotational history support the edge-driven model for microplate kinematics of Schouten and others to a good approximation. The Pacific-Nazca shear couple drove microplate rotation during phase 2, but development of the southeastern boundary enabled a transfer to the Nazca-Antarctic plate pair (phase 3). West Ridge propagation and reorganization of the south-western boundary may have decoupled the Pacific plate from the microplate, thus facilitating the shear couple transfer. The recent continued deceleration in microplate rotation rate and westward migration of the Pacific-Antarctic ridge axis relative to the microplate may indicate that the process of microplate "death" has begun. We speculate that the Juan Fernandez microplate will accrete to the Antarctic plate, perhaps within the next million years, like the extinct Friday microplate has done, thereby accomplishing another northward migration of the Pacific-Antarctic-Nazca triple junction. Our reconstructions illustrate that the Easter and Juan Fernandez microplates are more similar than previously thought in terms of their origin, growth, rift propagation, ridge segmentation and overall tectonic evolution.

Pesca exploratoria con trampas alrededor de las islas Robinson Crusoe y Santa Clara, archipiélago de Juan Fernández, Chile / Exploratory survey with pots around Robinson Crusoe and Santa Clara islands, Juan Fernandez archipelago, Chile  

Scientific Electronic Library Online (English)

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish Con el objeto de buscar recursos alternativos a la langosta de Juan Fernández (Jasus frontalis), que constituye el objetivo tradicional de los pescadores artesanales, se efectuó una campaña de pesca exploratoria con trampas en torno a las islas Robinson Crusoe y Santa Clara (Archipiélago de Juan Fer [...] nández, Chile). Entre el 11 de noviembre de 1996 y el 23 de marzo de 1997 se realizaron un total de 71 salidas de pesca, en las que se caló un total de 241 trampas, entre 50 y 1000 m de profundidad. En estas experiencias se utilizaron distintos diseños de trampas: troncocónico, tetragonal y piramidal, de diferente tamaño y ubicación de las entradas, y trampas langosteras con entrada en un extremo y en la parte superior. Las dos últimas, las utilizan los pescadores del archipiélago para la extracción de la langosta. Las trampas troncocónicas, tetragonales y piramidales fueron caladas con entradas circulares o rectangulares. Los únicos crustáceos capturados correspondieron a: langosta de Juan Fernández (Jasus frontalis), centolla de Juan Fernández (Paromola rathbuni), jaiba remadora (Ovalipes trimaculatus) y cangrejo dorado (Chaceon chilensis). La langosta se capturó entre 50 y 100 m; la centolla de Juan Fernández entre 100 y 300 m; el cangrejo dorado entre 200 y 1000 m; mientras que la jaiba remadora se encontró sólo en el veril de 100 m. El único recurso que presenta interés pesquero es C. chilensis, tanto por su abundancia como por la amplia distribución en profundidad y en torno a las islas analizadas Abstract in english Looking for alternative resources to the Juan Fernandez spiny rock lobster (Jasus frontalis), the traditional target species of the artisanal fishermen of the archipelago, an exploratory fishing campaign with fishing pots was conducted around Robinson Crusoe and Santa Clara islands. Between November [...] 11, 1996, and March 23, 1997, a total of 71 fishing journeys were conducted, during which 241 pots were set between 50 and 1000 m depth. In these experiences different pot designs were used: conical-trunk, tetragonal, piramidal, and lobster pots with a wicket on one extreme and lobster pot with an upper wicket. The last two, are the ones often used by the archipelago fishermen to catch lobsters. The conical-trunk, tetragonal and piramidal pots were with circular or rectangular wickets. The resources caught were: Juan Fernandez spiny rock lobster (Jasus frontalis), Juan Fernandez king crab (Paromola rathbuni), rowing crab (Ovalipes trimaculatus) and golden crab (Chaceon chilensis). The spiny rock lobster was captured between 50 and 100 m depth, while the rowing crab was found only in the 100 m isobath; Juan Fernandez king crab between 100 and 300 m and the golden crab between 200 and 1000 m. The only resource with fishing interest is C. chilensis, both by its abundance as well as for its wide distribution in depth and around these islands

“Don Juan-Fracture” as a Hint to Aortic Isthmus Rupture  

Science.gov (United States)

We report a case of thoracic aortic rupture after blunt trauma in a 23-year-old male patient. The initial investigation found no external injury or bleeding, only a slightly widened mediastinum and a broken left calcaneus. Abdominal lavage was negative, biochemistry was normal, and breathing and oxygenation were not compromised. When changing his position during diagnostics, the patient all of a sudden developed cardiac arrest and typical signs of hypovolemic shock. An immediate sternotomy was done without any further diagnostics on suspicion of aortic isthmus injury. A circular avulsion at the ligamentum arteriosum was found as assumed and repaired under cardiopulmonary bypass. The patient left the hospital for rehabilitation after 12 days in adequate health status. Biodynamics of blunt trauma after high-speed frontal impact and the relationship between calcaneus fracture, called “Don-Juan fracture,” and aortic rupture at the site of ligamentum arteriosum are discussed.

Biogeochemical variability of plants at native and altered sites, San Juan Basin, New Mexico  

Science.gov (United States)

The San Juan Basin is becoming a major energy resource region. The anticipated increase in strip mining for coal can be expected to alter the geochemical and biogeochemical environment. because such activities destroy the native vegetation communities, rearrange the rock strata, and disrupt natural soil development. This study investigated the variability in the biogeochemistry of native plant species at both undisturbed and altered sites and assessed the importance of the observed differences. Three studies are involved in this investigation: Study 1, the biogeochemical variability of native species found at sites throughout that part of the basin underlain by economically recoverable coal; Study 2, the biogeochemical variability of native species growing on soils considered favorable for use in the topsoiling of spoil areas; and Study 3, the biogeochemical variability of native species on rehabilitated sites at the San Juan coal mine. Summary statistics for concentrations of 35 elements (and ash yield) are reported in Study 1 for galleta grass, broom snakeweed, and fourwing saltbush. The concentrations of manganese, molybdenum, nickel, and uranium (and possibly iron and selenium) in galleta show regional patterns, with the highest values generally found in the south-central region and western edge of the study area. Differences in the concentration of elements between species was generally subtle (less than a factor of two) except for the following: ash yield of saltbush was two times that of the other plants; boron in snakeweed and saltbush was four times greater than in galleta; iron in galleta was two times greater than in saltbush; and, calcium, magnesium, potassium, phosphorus, and sulfur were generally highest in saltbush. Summary statistics (including the 95-percent expected range) for concentrations of 35 elements (and ash yield) are reported from Study 2 for galleta and broom snakeweed growing on the Sheppard, Shiprock, and Doak soil association. Significant regional (greater than 10 km) variation for aluminum, iron, sulfur, vanadium, and zirconium in galleta are reported; however, for most elements, a significant proportion of the variation in the data was measured locally (less than 0.1 km). This variation indicates that samples of galleta and snakeweed taken more than 10 km apart vary, in their element composition, little more than plants sampled as close together as 0.1 km. The concentrations of 35 elements (and ash yield) in alkali sacaton and fourwing saltbush, which were collected on a rehabilitation plot at the San Juan mine (Study 3), are compared with those of control samples of similar material from native sites from throughout the ,an Juan Basin. Concentrations of aluminum, arsenic, boron, cobalt, copper, fluorine, iron, lead, manganese, sodium, and uranium in samples of saltbush growing over spoil generally exceed the levels of these elements in control samples. For many elements, concentrations in mine samples are from two to five times higher 1 han concentrations in the control samples. Sodium concentrations i saltbush, however, were 100 times higher in mine samples than in control samples. This high concentration reflects a corresponding : OO-fold increase in the extractable sodium levels in spoil material s compared to C-horizon control samples. Sampled plants from the l1ine area, spaced relatively close together (5 m (meters) or less), vary greatly in their element compositions, apparently in response 1 J the heterogenous composition and element availability of the l1ine soils. Topsoiling to a depth of 20 cm (centimeters) does little to meliorate the uptake of elements from spoil by saltbush.

Structurally controlled and aligned tight gas reservoir compartmentalization in the San Juan and Piceance Basins  

Energy Technology Data Exchange (ETDEWEB)

Recurrent basement faulting is the primary controlling mechanism for aligning and compartmentalizing upper Cretaceous aged tight gas reservoirs of the San Juan and Piceance Basins. Northwest trending structural lineaments that formed in conjunction with the Uncompahgre Highlands have profoundly influenced sedimentation trends and created boundaries for gas migration; sealing and compartmentalizing sedimentary packages in both basins. Fractures which formed over the structural lineaments provide permeability pathways which allowing gas recovery from otherwise tight gas reservoirs. Structural alignments and associated reservoir compartments have been accurately targeted by integrating advanced remote sensing imagery, high resolution aeromagnetics, seismic interpretation, stratigraphic mapping and dynamic structural modelling. This unifying methodology is a powerful tool for exploration geologists and is also a systematic approach to tight gas resource assessment in frontier basins.

Biostratigraphic evidence of dramatic Holocene uplift of Robinson Crusoe Island, Juan Fernández Ridge, SE Pacific Ocean  

Directory of Open Access Journals (Sweden)

Full Text Available A study of the biostratigraphy and sedimentology of Holocene deposits on Robinson Crusoe Island (RCI on the Juan Fernández Ridge (JFR indicates that a~dramatic but localized uplift occurred since 8000 BP, at a rate of about 8.5 mm yr?1. In fact, supratidal flats and sand layers with marine gastropods (mostly Nerita sp. are now exposed ca. 70 m a.s.l., and covered by transitional dunes. The last volcanic activity on RCI occurred at ca. 0.8 Ma (active hotspot located 280 km further west and there is no sign of a compensating bulge that explains this uplift, isobaths of the sea floor instead suggesting general subsidence. However, modeling indicates that large-scale landslides followed by isostatic rebound are a viable explanation, partially reflected in the low-resolution bathymetry of the area.

Dibaxu: a comparative analysis of Clarisse Nicoïdski'?s and Juan Gelman'?s bilingual poetry  

Directory of Open Access Journals (Sweden)

Full Text Available This essay reads Argentine poet Juan Gelman'?s 1994 bilingual Ladino-­Castellano book Dibaxu in light of its intertextual relationship with Franco-­Bosnian author Clarisse Nicoïdski'?s work, especially her 1986 bilingual Ladino-­English poetry collection Lus ojus, las manus, la boca. I return to Gelman'?s text, written in a foreign, diasporic, and Jewish language in order to acknowledge Nicoïdski'?s work not only as a pre-­text, but as a fundamental intertextual source forDibaxu. In doing so, I observe the different reasons these two poets have to use the Ladino language: while Nicoïdski seeks to establish a link with her Sephardic community, Gelman uses the language to escape the limited trappings of a national identity. Both, however, work towards the maintenance, or survival, of Ladino.

Full Text Available In this paper, social protest phenomenon during Juan Manuel Santos’ first term is analyzed using political processes approach to study social movements. During Santos’ administration, free trade agreements and the “mining-energy locomotive” initiatives have spurred protests since they have brought perverse consequences to rural, education, and health sectors. Nonetheless, protests are not explained as a reaction of economic dynamics, but as a complex articulation between a favorable context —produced by the change in style between the previous administration (Uribe 2002-2010 and Santos’ one, hence, creating expectations and opportunities towards protestin —, and the active role of people mobilizing, which is expressed by the shaping of mobilization structures and the creation of novelty frameworks for collective action.

Modern Monarchs and Democracy: Thailand’s Bhumibol Adulyadej and Juan Carlos of Spain  

Directory of Open Access Journals (Sweden)

Full Text Available The history of democracy is typically a history of struggle against monarchs and other such autocrats. The elevation of one person over others by virtue of blood and birth has come to be seen as anachronistic; yet some monarchies have managed to survive to this day. This paper analyses two examples of the uneasy coalition between popular sovereignty and royal leadership that is constitutional monarchy. Whereas Juan Carlos of Spain has been described as having steered Spain away from dictatorship, Bhumibol of Thailand has come under scrutiny for allegedly lacking a principled approach to democracy. I argue that structural as much as personal factors influenced the ways in which the two monarchies were legitimised – one by positively responding to the modern aspirations of the king’s subjects, giving him a “forward legitimacy,” the other by revitalising the king’s traditional charisma and opting for “backward legitimacy.”

San Juan National Forest Land Management Planning Support System (LMPSS) requirements definition  

Science.gov (United States)

The role of remote sensing data as it relates to a three-component land management planning system (geographic information, data base management, and planning model) can be understood only when user requirements are known. Personnel at the San Juan National Forest in southwestern Colorado were interviewed to determine data needs for managing and monitoring timber, rangelands, wildlife, fisheries, soils, water, geology and recreation facilities. While all the information required for land management planning cannot be obtained using remote sensing techniques, valuable information can be provided for the geographic information system. A wide range of sensors such as small and large format cameras, synthetic aperture radar, and LANDSAT data should be utilized. Because of the detail and accuracy required, high altitude color infrared photography should serve as the baseline data base and be supplemented and updated with data from the other sensors.

Chagas urbano en San Juan. Diagnóstico, revisión y propuesta para un sistema integrado de ataque  

Directory of Open Access Journals (Sweden)

Full Text Available La ciudad de San Juan, Argentina, inserta en un oasis bajo riego, es y fue un área de fuerte prevalencia de la enfermedad de Chagas. Cambios ecológicos y socioambientales del complejo patógeno indican un avance significativo de su vector, Triatoma infestans, desde las zonas rurales, su hábitat tradicional, hacia el centro urbano. En este artículo se discuten los procedimientos empleados para medir este fenómeno, así como las técnicas de representación cartográfica. Tras un análisis geohistórico del problema, se revisa la situación actual a partir del vínculo entre vinchucas y palomas, estas últimas en su condición de reservorios, no facultados para albergar en su torrente sanguíneo el agente Trypanosoma cruzi pero sí para facilitar la movilidad del vector. Se concluye que resulta necesario atacar el problema a través de una estrategia integrada que considere el complejo patógeno con criterio transdisciplinario.REV ARGENT CARDIOL 2008;76:480-487.

Juan César García y el movimiento latinoamericano de medicina social: notas sobre una trayectoria de vida  

Directory of Open Access Journals (Sweden)

Full Text Available Este artículo analiza la trayectoria de Juan César García, uno de los referentes del movimiento latinoamericano de medicina social. La pregunta que desencadenó este trabajo buscó indagar el momento y las circunstancias en que García incorporó para sí la matriz del marxismo para pensar los problemas de salud. De esta manera, siguiendo los lineamientos metodológicos propuestos por Pierre Bourdieu, utilizamos la noción de "trayectoria de vida" para reconstruir un recorrido vital que se bifurca en varias rutas, de su Necochea natal a la ciudad de La Plata, desde allí hasta Santiago de Chile y, finalmente, sus innumerables viajes desde Washington hacia gran parte de América Latina. Para ello, realizamos entrevistas semiestructuradas con informantes clave, familiares, amigos y colegas de Argentina, Brasil, Ecuador y Cuba. Asimismo, analizamos los títulos de su biblioteca personal, donada a la fundación internacional que lleva su nombre, y documentos de distintos archivos particulares.

Sustainable development and culture - Some reflections for their search in the Alto San Juan  

International Nuclear Information System (INIS)

The economic processes in the upstream San Juan River are determined by decisions taken in cultural frames in which the traditional groups and peasants build in hybrid forms of existence according with their own history and the availability of resources in the territory. In this way, they alternate different production systems that introduce them in different social and economic groups: local, zonal, regional, national and trans national; each one with a specific rationality, impacting in a particular way, in agreement with the system of dominant production over the environment. The features of the society and culture that impact the economic decision making can be revealed and strengthened in a coherent strategy that respects the regional and group specificities and that looks for the sustainable development of the region

Submersible observations along the southern Juan de Fuca Ridge: 1984 Alvin program.  

Science.gov (United States)

In September 1984, the research submersible Alvin provided direct observations of three major hydrothermal vent areas along the southernmost segment of the Juan de Fuca Ridge (JFR). The submersible operations focuses on specific volcanologic, structural, and hydrothermal problems that had been identified during the preceding 4 years of photographic, dredging, acoustic imaging, and geophysical studies along a 12 km long section of the ridge. A continuously maintained (from 1981 to the present) net of seafloor-anchored acoustic transponders allowed the observations from Alvin to be directly tied to all previous USGS data sets and NOAA water column surveys from 1984 to the present. We review the dive program and present a brief synthesis of the geology of the vent sites together with sample and track line compilations.-from Authors

International Nuclear Information System (INIS)

In this project, measurement of x-ray radiation dose level during radiological examination in Jos university teaching hospital and Plateau State specialist hospital at different locations within the department were carried out using radiation survey meter. The results were converted from micro sievert per hour (?Sv/hr) to milisievert per year (mSv/yr). The radiation levels from the two hospitals visited ranged from 1.3m Sv/yr to 8.4m Sv/yr. This implies that all the radiology departments visited are still operating within the safety limit having less than 20 mSv/yr which is the standard permissible radiation level recommended per year

Analysis of causes for reject x-ray films as a quality assurance elements in diagnostic radiology in Jos university teaching hospital  

International Nuclear Information System (INIS)

The film reject rate and quality assessments studies were carried out at the Jos University Teaching Hospital. The rejected films collected and counted with respect to type, size and reasons for rejection were carried out for two calendar years. The observed reject rates were found to be nearly independent of the type of X-ray examination, which 68% of waste film reflected the nature and skills employed. The mechanical influence of equipment (machine fault is 11%, film rejection due to poor processing (dark room fault) was found to be 8% and for film rejection due to wrong identification, fogged film, uncooperating patient (patient movement) are 5%, 5% and 3% respectively. The deterioration in the quality of films and film processing conditions, ineffective quality assurance programs and inadequate regular staff training form a possible explanation for observed waste films which could have been avoided.

Crustal structure of the Central Precordillera of San Juan, Argentina (31°S) using teleseismic receiver functions  

Science.gov (United States)

The subduction of the Nazca plate under the South American plate around 31°S is characterized by flat slab geometry. The (Chilean) Pampean flat slab of Argentina associated with the subduction of the Juan Fernandez ridge lies in a region of a series of foreland uplifts corresponding to the thin-skinned Precordillera and basement cored Sierras Pampeanas ranges. The SIEMBRA project deployed 40 broadband stations in 2008-2009 in both the Precordillera and the Sierras Pampeanas with the aim to foster the understanding of the entire central Andean flat slab region. One of the SIEMBRA station (DOCA) located on the western flank of Sierra de la Invernada in the Central Precordillera appears particularly appropriate to study the crustal structure and eventually detect discontinuities related to terranes establishment. We thus performed a receiver function analysis using teleseismic data recorded at the DOCA station during the SIEMBRA project and from October 2011 to June 2012 using a broadband UNSJ (National University of San Juan) seismic station with the purpose to obtain crustal images with details of the intracrustal structure consistent with a mechanism that could explains both the observed earthquake depths and the uplift pattern in the Central Precordillera. Our results show that the Moho beneath the Precordillera lies at a depth of about 66 km. The Moho signal appears diminished and behaves irregularly as a function of azimuthal orientations. Although this observation could be the result of an irregular geometry it also correlates with the hypothesis of partial eclogitisation in the lower crust. Two mid-crustal discontinuities have also been revealed. The shallower one could correspond to a décollement level between the Precordilleran strata and the Cuyania basement at 21 km depth. The deeper one which the presence has been matched with a sharp decrease of the crustal seismic activity drove us to the hypothesis of a major change in crustal composition at 36 km. Finally the flat portion of the subducted slab has been imaged lying at about 100 km depth.

Adaptaciones metodológicas en la aplicación del análisis estratigráfico constructivo: el Santuario de San Juan de la Penyagolosa (Castellón y la iglesia de San Juan de los Reyes en Granada  

Directory of Open Access Journals (Sweden)

Full Text Available This text presents two cases of the application of stratigraphic wall study in which two specific adaptations, stemming from the original case of the building analysed, were developed. In the first case, the study of the Santuario de San Juan de la Peñagolosa, the notable size of the shrine meant that data collection and management were highly complex. For this reason, a methodology was tested whereby information was hierarchized, allowing it to be managed faster and more efficiently. In the second case, the study of the church of San Juan de los Reyes, a complementary study was carried out in addition to the stratigraphic wall study. The same construction technique used in the building (wall stonework with brick buttresses and limestone boulder caissons brought about the possibility of carrying out a study of the distribution of the weep holes.En este texto se presentan dos casos de aplicación del estudio estratigráfico constructivo en los cuales se desarrollaron dos adaptaciones específicas ocasionadas por el caso concreto del edificio analizado. En el primer caso, el estudio del Santuario de San Juan de la Peñagolosa, la notable dimensión del conjunto conllevaba una complejidad de recogida y gestión de la información. Por esta razón, se ensayó una metodología de jerarquización de la información que permitiera una gestión de la misma más rápida y eficaz. En el segundo caso, el estudio de la iglesia de San Juan de los Reyes, además del estudio estratigráfico se realizó un estudio complementario. La misma técnica utilizada en el edificio (fábricas de machones de ladrillo y cajones de cantos rodados y cal sugirió la posibilidad de realizar el estudio del ritmo de la distribución de los mechinales.

Aproximaciones culturales al mito de Don Juan en las obras de Tirso de Molina, Molière y Zorrilla  

Directory of Open Access Journals (Sweden)

Full Text Available This article examines how the myth of Don Juan that has been retold and heard in several countries beyond Spain – France, Italy, England, the Americas – continues to seduce and fascinate both the general public and lovers of literature alike. The influence of this myth is such that these days almost everyone is familiar with his tongue, as the way a snake does with its gaze, always after women, ever in pursuit until he conquers them. The smooth evolution of this myth over almost four centuries has suffered great changes. For this reason, an examination of the changing personality of Don Juan through time seems appropriate, in what concerns to arrogance, ostentation, and theatricality characterization not only the seventeenth century persona, but also his modern incarnations. It is this very permanence of the game, which compels us to look for what is behind the mask.

Tonos eclesiásticos versus Tonalidad Mayor-Menor. Juan Bermudo: práctica musical y hábitos de escucha en el siglo XVI  

Directory of Open Access Journals (Sweden)

Full Text Available As it is well-known, the change of the tonal system, which introduced the emergence of the harmonic tonality, lies in the 16th century. Until then, the diatonic tonal system was prevalent and based upon two theoretical pilars: firstly, upon the hexachord-system and secondly, upon the system of modes. One central aspect in Juan Bermudo’s treatise Declaración de instrumentos musicales (Osuna, 1555 is his observation that the musical practice of his time is in contradiction with these theoretical fundaments. With the aim to conciliate traditional theory and contemporary practice, he proposes some new concepts which are illustrated also by musical examples from Spanish composers.Como es sabido, en el siglo XVI se produce un paso desde el sistema tonal tradicional hacia la tonalidad armónica. Hasta entonces, dominaba el sistema diatónico, que se basaba en dos pilares teóricos: primero, en el sistema de los hexacordos; y segundo, en el sistema de los modos. Uno de los aspectos centrales en el tratado Declaración de instrumentos musicales (Osuna, 1555 de Juan Bermudo, contiene sus observaciones a propósito de la práctica musical de su tiempo, que no correspondía ya a los susodichos principios teóricos. Con la intención de conciliar la teoría tradicional y la práctica musical contemporánea, Bermudo propone algunos conceptos nuevos, sirviéndose también de ejemplos musicales de compositores españoles. [de] Kirchentöne versus Dur-Moll-Tonalität. Juan Bermudo: Aufführungspraxis und Hörgewohnheiten im 16. Jahrhundert Der Umbruch des Tonsystems, mit dem die Ausbildung der Dur-Moll-Tonalität eingeleitet wurde, ist bekanntlich im 16. Jahrhundert anzusiedeln. Bis dahin dominierte das diatonische Tonsystem, das auf zwei theoretischen Grundpfeilern basierte: erstens auf dem Schema der Klangstufen (Hexachorde und zweitens auf der Moduslehre. Dass diese theoretische Basis der zeitgenössischen Musikpraxis nicht mehr gerecht wurde, bildet einen zentralen Aspekt in Juan Bermudos Traktat Declaración de instrumentos musicales (Osuna 1555, in dem er neue Konzepte zur Aussöhnung dieses Widerspruchs vorschlägt und dafür auch Beispiele spanischer Komponisten anführt.

Low-temperature (typically 5–75°C) fluid, commonly referred to as "diffuse" hydrothermal flow, emanates from fractures over a significant portion of the Juan de Fuca Ridge seafloor in the Northeast Pacific Ocean (Kelley et al., 2012, in this issue). Although some fraction of the diffuse effluent becomes entrained relatively quickly into nearby plumes from high-temperature sources, a number of studies suggest that a significant portion flows laterally as discrete low-level plumes that remai...

Abundance, distribution, and feeding patterns of juvenile coho salmon ( Oncorhynchus kisutch) in the Juan de Fuca Eddy  

Science.gov (United States)

The Juan de Fuca Eddy is a seasonal, counter-clockwise gyre off the mouth of the Strait of Juan de Fuca between Washington, USA and British Columbia, Canada that may provide favorable feeding habitat for juvenile coho salmon ( Oncorhynchus kisutch) during their early marine existence. In late September 2002, physical and biological sampling was conducted along two transects of the eddy region. Surface rope trawling was conducted to capture juvenile salmon and other nekton, along with bongo and neuston net tows to examine potential mesozooplanktonic salmon prey. Presence of the Juan de Fuca Eddy was confirmed with vertical water profiles. In addition, nutrient and chlorophyll a concentrations collected from 3-m depth were within the range observed in previous studies within the eddy region. In the mesozooplankton community, euphausiids, chaetognaths, and decapod megalopae were common. In the diet of juvenile coho salmon, euphausiids and decapod megalopae were dominant by percent number, and larval and juvenile fish were dominant by percent weight. Feeding intensity (percent body weight) based on stomach contents was variable, but not significantly different among stations. To compare the Juan de Fuca Eddy region with an upwelling area, we sampled along a transect off La Push (LP), Washington, USA which is south of the eddy. The eddy region was found to be less productive than the LP transect. Nutrients were lower, chlorophyll a concentrations were higher, and zooplankton abundance was generally higher along the LP transect than in the eddy region. In addition, more juvenile coho salmon were captured from the LP transect than the eddy region. Prey items in stomachs of salmon from the LP transect were heterogeneous compared to those from the eddy region. Feeding intensity along the LP transect was slightly lower and more variable than in the eddy region, and differences in feeding intensity among LP stations were significant. In addition, feeding intensities among stations nested within regions were significantly different.

Rapports de parenté et de production à San Juan, haute vallée du Chancay, Pérou  

Directory of Open Access Journals (Sweden)

Full Text Available Les relations de parenté dans l'organisation des communautés andines sont particulièrement importantes, ce qui est aussi le cas à San Juan. L'utilisation et la distribution de l'eau en fonction de 'turnos' se font selon diverses combinaisons basées sur les relations de parenté. Il est vraisemblable que l'organisation des tours à l'intérieur du village et par quartiers se fasse également en fonction de la distribution des familles. L'élevage est aussi lié à ces relations de parenté, en particulier l'élaboration des fromages: les femmes ont ici une place prépondérante, tout comme pour l'irrigation. Ainsi les relations de parenté constituent un capital précieux, mais seulement dans le cas d'une société traditionnelle fonctionnant par prestations mutuelles. Or, on assiste actuellement à un développement du travail libre favorisé par les possibilités d'accumulation individuelle d'argent (vente de fruits, des produits de l'élevage. La division sexuelle du travail est envisagée en fin d'article. Las relaciones de parentesco en la organización de las comunidades andinas son particularmente importantes, lo cual también es el caso de San Juan. La utilización y distribución del agua, en función de 'turnos' se efectúa de acuerdo a diversas combinaciones basadas en las relaciones de parentesco. Es verosímil que la organización de turnos para el agua en el interior del pueblo y por barrios se efectúe igualmente en función de la distribución de las familias. La cría de ganado también estaba ligada a estas relaciones de parentesco, sobre todo la elaboración de quesos: en esto las mujeres tienen un lugar preponderante, así como para la irrigación. Así pues las relaciones de parentesco constituyen un capital precioso, pero tan solo en el caso de una sociedad tradicional que funcione por prestaciones mutuas. Ahora bien, actualmente se asiste a un desarrollo de trabajo libre favorecido por las posibilidades de acumulación individual de dinero (por venta de frutas, o productos de la crianza de ganado. La división sexual del trabajo es observada atentamente al final del artículo. Relations of relationship in the organization of andean communities are particularly important and this is also the case of San Juan. Utilization and distribution of water in function of the turnos are also related to different combinations based upon relations of relationship. It is probable that the organization of water turns in the village itself and by parts is also related to family distribution. Cattle raising is also tied to these relations of relationship, principally for the elaboration of cheese: there women play an important part as for the irrigation. So, relations of relationship settle a precious capital, but only in the case of a traditional society functioning by mutual prestatations. Now, we will see today free work development helped by possibilities of individual accumulation of money (fruit and cattle raising product selling. At the end, we will consider sexual work differentiations.

Resistivity cross section through the Juan de Fuca Subduction System and its tectonic implications  

Science.gov (United States)

A resistivity cross section to depths exceeding 200 km has been derived from magnetotelluric observations along a profile near latitude 45°N from the Juan de Fuca spreading center, across the coastal subduction complex, the High Cascades volcanic arc, and into the back-arc Deschutes Basin region. In this two-dimensional interpretation, emphasis was placed on data approximating the transverse magnetic mode since these data are relatively robust to common departures from the two-dimensional assumption. The vertical magnetic field, however, has been very valuable in defining structure of the offshore sediments, of the oceanic asthenosphere and below the arc volcanics of the Western and High Cascades. The transverse electric data on land suffer a variety of three-dimensional effects, making their interpretation very difficult. In contrast, the greater uniformity of upper crustal conditions on the seafloor allowed a good fit to both modes of the impedance plus the vertical magnetic field at least down to 104 s. Important components of our model resistivity structure and their hypothesized tectonic implications are as follows. Measurements on the seafloor indicate very low resistivity in the eastward thickening sedimentary wedge of the abyssal Cascadia Basin provided its depth extent is constrained. The majority of these sediments are inferred to be off-scraped or lose most of their interstitial water before being carried more than ten or so kilometers down the trench. In the oceanic upper mantle of the Juan de Fuca plate, moderately low resistivities from about 35-215 km depth (nominal) presumably reflect up to several percent partial melt attending regional upwelling in the vicinity of the ridge. Very low resistivities below 215 km depth in the oceanic mantle are difficult to explain physically, but problems with very long-period source field effects or bias error may hamper the modeling here. Under the Oregon Coast Range, a low-resistivity layer dips inland at approximately 20°. Its conductance decreases by an order of magnitude from the coast to around 60 km inland and its position appears consistent with the Juan de Fuca plate subduction decollement. Possible causes of the low-resistivity include residual sediments, pore waters, perhaps sulfides, and dehydrating oceanic crust carried down the subduction zone. East of about 60 km inland, there is a much stronger, subhorizontal conductor with a depth to top of around 25 km. To explain it, a massive breakdown of greenschist minerals is hypothesized to liberate most of the water carried in the altered ocean crust well before the volcanic arc is reached. The resistivity manifestation of the arc magmatism itself is not strong but consists of a low-resistivity axis in the middle crust below and to the west of the arc at the surface. It presumably represents fluids released from crystallizing magmas. East of the High Cascades, both the MT and geomagnetic data detect a strong gradient in resistivity with lower values to the south. It is suggested that the Brothers fault zone signifies an electrical, thus possibly a thermal and magmatic, boundary with the northern Basin and Range.

Se intenta mostrar que esta clave de lectura permite un ac [...] ceso privilegiado a la labor de Guerrero, a la vez que ayuda a construir una imagen más compleja y matizada de la generación intelectual "antipositivista" a la que perteneció. La olvidada obra de Guerrero se compone principalmente de trabajos sobre ética, psicología y estética. Acotaremos nuestra atención a su principal trabajo, y acaso la obra sobre estética más ambiciosa jamás escrita en nuestro país: Estética Operatoria en sus Tres Direcciones. Se muestra en el artículo que la summa estética de Guerrero, si bien expresa con toda claridad las preocupaciones centrales de una generación intelectual marcada por la cultura alemana de entreguerras y por la problemática de la "crisis de la cultura", inscribe, a su vez, una anomalía -benjaminiana-, una inflexión político-materialista, que pone en cuestión la idea frecuente de que la "crisis de la cultura" una y otra vez diagnosticada en aquella época mostró siempre alternativas "espiritualistas" de resolución.

It is shown that this perspective allows a privileged access to Guerrero's work, at [...] the same time that it makes more complex the image of the "anti-positivistic" intellectual generation in Argentina. Guerrero's forgotten work includes principally contributions on ethics, psychology and aesthetics. This essay will pay attention only to his most important work, maybe the most ambitious aesthetic work ever written in Argentina: Operatory Aesthetics in its Three Directions. This aesthetic summa, although it expresses the typical features of an intellectual generation marked by German interwar culture and the concerns on the "culture crisis", it also inscribes a benjaminian anomaly, a political-materialistic inflection, that questions the frequent opinion that the "culture crisis" in those years diagnosed always showed "spiritualist" answers.

A GPR survey on degraded permafrost at Mesón San Juan, Mendonza, Argentina  

Scientific Electronic Library Online (English)

Full Text Available Este estudo apresenta alguns resultados geofisicos obtidos no Mesón San Juan localizado na Cordilheira dos Andes (6.012 m, 33°30'S e 69°49'W), na divisa entre a Argentina e o Chile. Oplatô de permafrost (4.400 m) está situado na base da geleira, limitado por morenas produzidas por fenômenos criogê [...] nicos recentes. Os resultados geofisicos mostraram variações laterais nas características dielétricas na subsurperfície devido a diferentes porcentagens de água, permitindo o zoneamento qualitativo da estrutura do permafrost . As permissividades elétricas foram comparadas de um modo semiquantitativo através do procedimento de migração "trial-and-error", tirando proveito do "clutter" do permafrost . Foi possível reconhecer uma zona confinada de baixa velocidade de fase, que indica porosidade e quantidade de água mais elevadas. Essa zona foi interpretada como sendo permafrost degradado, provavelmente resultante do impacto do aquecimento global sobre o ambiente glacial andino, possível canal de descarga de um suprapermafrost a um aqüífero subpermafrost , parte de um sistema raso e descontínuo, não mapeado neste trabalho. Abstract in english This work presents some geophysical results obtained at Mesón San Juan located in the Central Andes (6,012 m, 33°30' Sand 69°49' W), on the border of Argentina and Chile. The permafrost plateau (4,400 m) situated at the loot of the glacier is limited by recent moraines produced by cryogenic phenom [...] ena. The geophysical results revealed lateral differences in the dielectric characteristics of the subsurface due to varying water contents, allowing a zoning of the permafrost structure. We have compared the electrical permittivities in a semi-quantitative way through a trial-and-error migration procedure, taking advantage of the clutter present in the permafrost as seen in the fixed-offset data. In this way we were able to recognize a confined zone of relatively low phase velocity indicating higher porosity and water content. We interpret that zone as degraded permafrost , probably a result of the impact of global warming on the Andean cryolithozone. That zone is likely a discharge channel linking a suprapermafrost to a subpermafrost aquifer, part of a laterally discontinuous near surface system not mapped in this work.

Speaking Up / Coming Out: Regions of Authenticity in Juan Pinzás's Gay Galician Dogma Trilogy  

Directory of Open Access Journals (Sweden)

Full Text Available While Dogme 95 is often associated exclusively with Scandinavia, its manifesto and Vow of Chastity were taken up by filmmakers from across Europe as well as in North and South America. The three films made according to the format in Spain are the work of director Juan Pinzás (b. Vigo, 1955 and comprise the 'Trilogía de la vida, de amor, y de sexo': Era outra vez (2000, Días de voda (2002, and El desenlace (2005. The last film in the Spanish trilogy was also the final film to receive official certification from the Dogme 95 movement. The article argues that Pinzás exploits the strait-jacket of Dogme, in particular its rules about the use of sound, to focus attention on diglossia in Galicia and in order to portray as naturalistic the use of the Galician language on screen and between younger speakers. It also contends that the trilogy explores in parallel two coming-out processes: one which would affirm a gay man's true sexual identity and another which authenticates the Galician-speaking status of young middle class characters. The article finds that this parallel reading is complicated by the third instalment of the trilogy, in which key roles are played by new actors speaking in Spanish.

Microbial Life in Ridge Flank Crustal Fluids at Baby Bare Seamount, Juan de Fuca Ridge  

Science.gov (United States)

To determine the microbial community diversity within old oceanic crust, a novel sampling strategy was used to collect crustal fluids at Baby Bare Seamount, a 3.5 Ma old outcrop located in the northeast Pacific Ocean on the eastern flank of the Juan de Fuca Ridge. Stainless steel probes were driven directly into the igneous ocean crust to obtain samples of ridge flank crustal fluids. Genetic signatures and enrichment cultures of microorganisms demonstrate that these crustal fluids host a microbial community composed of species indigenous to the subseafloor, including anaerobic thermophiles, and species from other deep-sea habitats, such as seawater and sediments. Evidence using molecular techniques indicates the presence of a relatively small but active microbial population, dominated by bacteria. The microbial community diversity found in the crustal fluids may indicate habitat variability in old oceanic crust, with inputs of nutrients from seawater, sediment pore-water fluids and possibly hydrothermal sources. This report further supports the presence of an indigenous microbial community in ridge flank crustal fluids and advances our understanding of the potential physiological and phylogenetic diversity of this community.

Sedimentary history and economic geology of San Juan Basin, New Mexico and Colorado  

International Nuclear Information System (INIS)

The San Juan Basin contains up to 15,000 ft of sedimentary rocks ranging in age from Cambrian to Recent. The earliest development of the area as a sedimentary basin or trough apparently took place in Pennsylvanian time, and the basin was maintained, with changing rates of subsidence and filling, through the remainder of geologic time. During the Early Paleozoic, sedimentation was dominated by marine transgressions across the northwestern flank of the regional Transcontinental Arch. The Late Paleozoic history was strongly influenced by tectonism related to development of the Ancestral Rocky Mountains Uplifts and associated downwarping. The Early Mesozoic is characterized by fluvial and eolian environments, interrupted periodically by thin marine transgressive deposits of nearshore redbeds. The final Mesozoic event was the widespread Late Cretaceous marine transgression which deposited a thick cyclic sequence of marine gray shale and sandstone, with interbedded coal. Late Tertiary regional uplift and resulting volcanism were accompanied by a regional dissection of the area by stream systems that evolved into the present drainage pattern of superposed streams. The sedimentary history is directly related to the occurrence of economic deposits in the basin. Major reserves of petroleum and gas are in Cretaceous and Pennsylvanian rocks, coal in Cretaceous, and uranium in Jurassic and Cretaceous. Abstract only

The Effect of Saturation on the Slope Sliding in the San Juan de Grijalva Comunity, Chiapas  

Directory of Open Access Journals (Sweden)

Full Text Available A number of slopes that have been stable during many years may fail when an extraordinary rain period occurs. This phenomenon involves not only the lithology, the geometric and the mechanical characteristics of the slope but also the rain-evaporation-infiltration regime of the site. In this paper, the stability of a slope in the comunity of San Juan de Grijalva, Ostuacán, Chiapas (Mexico that failed during an intense raining period is analyzed. The volume of this slide was over 5 millions of cubics meters of soil and it produced the obstruction of the Grijalva river. The stratigraphic and geometric properties of the slope were determined and undisturbed samples were obtained in the site to determine the mechanical properties of the material. The stability analysis considered the variation of the cohesion of the soil caused by wetting and it was possible to observe the evolution of the safety factor with the water content of the material. Through the analysis of the rain infiltration and the stability of the slope, it has been possible to reproduce the failure process.

Hydrological response to a seafloor spreading episode on the Juan de Fuca ridge.  

Science.gov (United States)

Seafloor hydrothermal systems are known to respond to seismic and magmatic activity along mid-ocean ridges, often resulting in locally positive changes in hydrothermal discharge rate, temperature and microbial activity, and shifts in composition occurring at the time of earthquake swarms and axial crustal dike injections. Corresponding regional effects have also been observed. Here we present observations of a hydrological response to seafloor spreading activity, which resulted in a negative formation-fluid pressure transient during and after an earthquake swarm in the sediment-sealed igneous crust of the Middle Valley rift of the northernmost Juan de Fuca ridge. The observations were made with a borehole seal and hydrologic observatory originally established in 1991 to study the steady-state pressure and temperature conditions in this hydrothermally active area. The magnitude of the co-seismic response is consistent with the elastic strain that would be expected from the associated earthquakes, but the prolonged negative pressure transient after the swarm is surprising and suggests net co-seismic dilatation of the upper, permeable igneous crust. The rift valley was visited four weeks after the onset of the seismic activity, but no signature of increased hydrothermal activity was detected in the water column. It appears that water, not magma, filled the void left by this spreading episode. PMID:15254534

[Social thinking in health in Latin America: revisiting Juan César García].  

Science.gov (United States)

The article reconstitutes the social thinking in health by Argentine physician and sociologist Juan César García (1932-1984), analyzing the main publications approaching his work and activities. The article situates his thinking in the two fields that marked his production: social medicine and the social sciences from the 1960s to the late 1980s. The article highlights his work with the Pan American Health Organization and his perspective of analyzing social medicine and the social sciences by relating them not only to the Latin American historical, social, economic, and political context, but also to historical materialism: linking medicine to the social structure; the influence of the social structure on the production and distribution of diseases; internal analysis of the production of medical services; and the relationship between training of health personnel and the medical field. As demonstrated, even today his work can be a reference for the discussion of such themes as medical education, health personnel training, the role of science and technology, the social sciences in medical education, and historical aspects of public health.

Biogeography and historical demography of the Juan Fernandez Rock Lobster, Jasus frontalis (Milne Edwards, 1837).  

Science.gov (United States)

The genetic structure of present-day populations has been highly affected by glacial periods and physical oceanographic forcing, particularly with respect to species distributions and population gene-flow patterns. We assessed the current genetic composition of the Jasus frontalis population in the southeastern Pacific Islands off the coast of Chile to evaluate their connectivity modulated by contemporary and historic oceanographic processes. Population structure and demographical history for this species were assessed based on classic and Bayesian approaches using 84 sequences of cytochrome oxidase subunit I. In addition, we estimated the time of origin of J. frontalis in the different geographic zones. The analyses show a panmictic population with high gene flow between subcomponents and a lack of genetic structure (F (ST) mesoscale oceanographic factors such as eddies and meanders. In a historical spatial context, the most probable common ancestor of J. frontalis could have colonized the region around 0.258 million years before present (MYBP), first becoming established in the Juan Fernández Archipelago and then expanding toward the Desventuradas Islands. The demographic history shows a consistent increase in the effective population size (N ( e )) starting approximately 0.130 MYBP, which is highly correlated with sea-level changes during the last glacial maximum.

Immunomodulatory activity of a Chinese herbal drug Yi Shen Juan Bi in adjuvant arthritis  

Directory of Open Access Journals (Sweden)

Full Text Available Objective: To investigate the immunomodulating mechanisms of a Chinese herbal medicine Yi Shen Juan Bi (YJB in treatment of adjuvant arthritis (AA in rats. Materials and Methods: Levels of serum tumor necrosis factor alpha (TNF-? and interleukin-1? (IL-1? were measured by the Enzyme-Linked Immunosorbent Assay (ELISA. Expression of TNF-? mRNA and IL-1? mRNA in synovial cells was measured with the semi-quantitative technique of reverse transcription-polymerase chain reaction (RT-PCR, while caspase-3 was examined by western blot analysis. Results: The administration of YJB significantly decreased the production of serum TNF-? and IL-1?. It also decreased significantly the TNF-? mRNA, IL-1? mRNA, and caspase-3 expression in synoviocytes. Conclusions: YJB produces the immunomodulatory effects by downregulating the over-activated cytokines, while it activates caspase-3, which is the key executioner of apoptosis in the immune system. This may be the one of the underlying mechanisms that explains how YJB treats the rheumatoid arthritis.

Profile of prospective bioengineering students at National University of San Juan  

Energy Technology Data Exchange (ETDEWEB)

The low percentage of students (43 % of applicants) that passed the entrance exams for the bioengineering career at the National University of San Juan in 2007, plus the historical situation of desertion in first year (about 50%), motivated the application of a diagnostic test to prospective students of this career. The aim of this test was to obtain information about the competences acquired by students to solve problems in different contexts using basic mathematical tools, reading comprehension skills to understand texts, graphs and tables. Although this test was sat by the entire population of applicants of the current school year, only the results belonging to bioengineering students are the ones presented for the purpose of this work. However, students of other disciplines of the school of engineering also have similar problems. From the analysis of the answers to the different items, it can be observed that there are serious difficulties in the development of basic capacities to successfully take the courses of this career.

Restoring sedges and mosses into frost heaving iron fens, San Juan Mountains, Colorado  

Directory of Open Access Journals (Sweden)

Full Text Available Rare iron fens in the San Juan Mountains of Colorado are frequently in poor condition due to mining, roads and ditches, which have left much of the fen completely bare of vegetation. Natural revegetation is slow to occur in the bare areas because of severe frost heave in the cold mountain climate. Therefore, experimental revegetation plots were conducted in a factorial design with mulching and no mulching, crossed with moss diaspores, sedge transplants, and moss and sedge combined. Mulching influenced surface soil temperatures by reducing the midday highs and increasing the night-time lows, which decreased the frequency and amount of frost heave. Peat moisture also modified frost heave, with the greatest frost heaving occurring near 75 % peat moisture content (water table 10–20 cm below the surface and the least when soils were either wetter or drier. Moss survival was dependent on mulch, with no moss surviving in plots without mulch. Mulching also increased sedge transplant survival. In summary, mulching significantly increased the success of vegetation restoration efforts for frost heave areas in mountain fens.

Sea Breeze Juan de Fuca transmission project : combined interconnect impact and facility study : summary report  

Energy Technology Data Exchange (ETDEWEB)

The Juan de Fuca (JDF) cable is a 550 MW High Voltage Direct Current (HVDC) submarine transmission line that will link Port Angeles, in Washington State, to South Vancouver Island. The objective of this combined interconnection impact and facility study is to determine the impact of this interconnection to the BC Transmission Corporation (BCTC) system in early 2010, specifically on Vancouver Island. The study involved the following tasks: load flow study; transient stability study; EMTP study; harmonic impedance analysis; insulation coordination study; evaluation of remedial action schemes (RAS); interconnection impact study report; and facility project plan study. The steady state and dynamic performance of the BCTC system on central Vancouver Island were assessed based on both normal operation and the predefined contingency conditions. Three load condition cases were considered, notably heavy winter 2010, light summer 2010 and light summer 2011. Cost estimates were provided along with lead times for the construction of transmission, station, protection and control, and telecom facilities and their auxiliary systems. It was concluded that the JDF cable will complement the existing grid and will add needed reliability, capacity and flexibility to transmission operations in the region. The JDF cable will strengthen British Columbia's electrical reliability and will meet Vancouver Island's electricity needs. According to the study, the cable will not result in any considerable steady state problems under both normal and contingency conditions. refs., tabs., figs.

Uranium hydrogeochemical and stream sediment reconnaissance in the San Juan Mountains, Southwest Colorado  

International Nuclear Information System (INIS)

From 1995 sites in the San Juan Mountains area, 1706 water and 1982 sediment samples were collected during June--July 1976 and analyzed for uranium. The area includes the southern third of the Colorado mineral belt which has yielded rich ores of gold, silver, copper, lead, zinc, and molybdenum. The broadly domed mountains are capped by 2500 m of Tertiary volcanics, deeply eroded to expose a Precambrian crystalline core. Adjacent plateaus underlain by Mesozoic sedimentary rocks were included in the reconnaissance. Average value of uranium in water samples from mountains was less than 0.5 ppB, from plateaus was 1 to 2 ppB, from Mancos shale areas exceeded 2 ppB. Anomalous sediment samples, 40 ppM uranium, came from near Storm King Mountain and upper Vallecito Creek. Other anomalous areas, including the Lake City mining district, were well defined by 4 to 30 ppM uranium in sediment and 3 to 30 ppB uranium in water. Anomalous areas not previously reported indicate favorable areas for future exploration

From surfaces to magnetic properties: special section dedicated to Juan Rojo  

Science.gov (United States)

Surface physics and magnetism, in particular the connection between surface defects, reduced dimensionality or size, crystal structure, electronic density of states and the mechanical and magnetic properties of solids, were always at the core of Juan Rojo's scientific interest and output. Both fields seem to meet at the nanoscale, a privileged playing field which is ideal for testing theoretical concepts, exploring new physics or probing a wealth of new, stunning and unheard-of applications. Upon reducing size or dimensionality, either in bulk systems or in thin films, surfaces and surface effects are telling. Thus, for instance, an ultra-thin coating can make nanoparticles of non-magnetic materials exhibit magnetic behaviour; or atomic steps can modify the local mechanical properties of a metallic single crystal. In this special section there are eight invited papers by disciples and close collaborators of Juan Rojo, that cover an ample spectrum of the above mentioned topics. The first paper, by Palacio et al, investigates the temperature and oxygen partial pressure conditions for FeO mono- and bi-layer growth on Ru(0001). The following paper, by Cortés-Gil et al, reports on the dramatic change in the electric resistivity of the manganite perovskite (La0.5Ca0.5)z MnO3 as a function of Ca content, an effect related to the removal of a charge-ordered state and a magnetic transition. Baeza et al study biomaterials for bone cancer treatment and skeletal reinforcing, as well as targeted magnetic nanoparticles used for intracell hyperthermia in cancer therapies. In the following paper, Marcano et al, assisted by a multi-technique approach, revisit the extraordinarily rich magnetic phase diagram of the Kondo system CeNi1- x Cux down to 100 mK temperatures. The magnetic field dependence of the martensitic transition temperature of the meta-magnetic shape memory alloy Ni50Mn34.5In15.5 in a crystalline and amorphous phase, in fields up to 13 T, is the subject of the paper by Barandiarán et al. In the following paper, Crespo et al review the effect of organic and inorganic coatings on magnetic nanoparticles, showing that the coating can tune the magnetic properties of metallic and oxide nano-sized particles. Barja et al report on ordered magnetic ion structures formed by evaporation of Mn and Fe on self-assembled layers of tetracyanoquinodimethane (TCNQ) molecules on Cu(111). Finally, Rodríguez de la Fuente et al investigate the role of surface defects on the physico-chemical properties of metals and oxides in a variety of scenarios, showing how the surface controls the mechanical properties probed at the nanoscale or the chemical reactivity.

Mineralogy and chemistry of massive sulfide deposits from the Juan de Fuca Ridge.  

Science.gov (United States)

Two types of massive sulphide were dredged from one of the six vent sites located in the axial valley of the southern Juan de Fuca ridge. Type A samples are angular slabs of dark grey Zn-rich sulphide with interlayers and a thin, partly-oxidized crust of Fe-sulphide. These layered sulphide aggregates appear to be fragments of a sulphide wall enclosing an active hydrothermal vent. The outer sulphide wall is composed of colloform Fe sulphide and Fe-poor sphalerite deposited under low-T conditions when sea-water and hydrothermal fluid mix above the discharge point. Inside the wall the intensifying hydrothermal sytem deposits a higher-T assemblage of granular Fe-rich sphalerite, wurtzite, pyrite and minor Cu-Fe sulphide. Type B sulphide samples are sub-rounded, spongy-textured fragments composed almost entirely of dendritic aggregates of pale Fe-poor colloform sphalerite and opaline silica. This type of sulphide is deposited in settings peripheral to sites of focused discharge and in open spaces by moderate- to low-T fluid discharging at a slow but variable rate; the fluid becomes increasingly oxidizing, resulting in late-stage deposits of hematite, baryte and sulphur.-L.di H.

Revisión estratigráfica y litofacial de la Formación La Silla (Ordovícico Inferior en la Precordillera Oriental de San Juan, Argentina Stratigraphic revision and lithofacies of La Silla Formation (Lower Ordovician in the eastern Precordillera of San Juan, Argentina  

Directory of Open Access Journals (Sweden)

Full Text Available La Formación La Silla (Cámbrico Superior - Ordovícico Inferior fue definida en 1994 por Keller et al. a partir de los niveles inferiores de la Formación San Juan. Esta Formación consiste en una sucesión distintiva de calizas claras, con escasos fósiles y muy explotadas por su alta pureza. Basados en estudios detallados en la sección tipo cercana a Jáchal y siete secciones en el área sur cercana a la ciudad de San Juan, proponemos una subdivisión formal para la Formación La Silla en tres miembros. La división de la unidad está basada en la ubicación preferencial de bancos dolomíticos en el sector central de la Formación mientras que el sector superior e inferior son calizas monótonas. Los miembros se denominan, de base a techo: Miembro Río del Agua, Miembro Río Blanco y Miembro Río Salado (85, 140 y 81 m, respectivamente. Las dolomías en el Miembro Río Blanco son de dos tipos: macizas, potentes y generalmente asociadas a chert; y dolomías con laminación planar y/o entrecruzada, ambas fácilmente distinguibles a simple vista, otorgándole a este Miembro un aspecto bandeado debido a la alternancia entre calizas y dolomías. Esto contrasta con el aspecto macizo y monótono de los Miembros restantes con estratificación tabular y a veces suavemente ondulante. Se reconocen las facies de grainstone peloidal, grainstone oolítico, rudstone intraclástico, packstone peloidal, mudstone, microbiales laminadas y trombolíticas. Además se describen las nuevas facies de dolomías laminadas y dolomías macizas. De la misma manera que lo observado por Keller et al. (1994, la Formación La Silla representa una fase distinta en la sucesión cambro-ordovícica, con las dolomías perimareales de la Formación La Flecha por debajo y las calizas fosilíferas de plataforma abierta de la Formación San Juan por encima.The Cambro-Ordovician carbonate platform succession of the Precordillera Oriental of western Argentina is some 2000 m thick and consists of five formations, from base to top, La Laja, Zonda, La Flecha, La Silla and San Juan (Keller, 1999; Bordonaro, 2003. La Silla Formation (latest Cambrian-Early Ordovician was defined by Keller et al. (1994 from the lower part of the San Juan Formation. It reaches some 350 m in thickness and consists of a distinctive succession of dominantly light-coloured, poorly fossiliferous limestones. The upper part of La Silla Formation is extensively quarried because of the remarkable purity of the limestones. Based on a detailed study of the type section in the northern outcrop area near Jáchal and seven sections in the southern area near San Juan (Fig. 1a, we propose a formal stratigraphic subdivision of La Silla Formation into three members. These are, from base to top, the Río del Agua Member, Río Blanco Member and Río Salado Member (Fig. 1b, which are 85, 140 and 81 m in their respective type sections. This subdivision is based in the preferential occurrence of creamcoloured dolostones interbedded in the middle part of the formation, whereas the lower and upper members are essentially monotonous limestones. Keller (1999 erected an informal tripartite subdivision conforming to three putative, shallowing-upward sequences, with the boundaries recording abrupt changes in relative sealevel. We do not detect this pattern and our proposed members do not coincide with this subdivision. We recognize nine individual lithofacies types (Fig. 2a-f. These are for the most part similar to those determined by Keller (1999 and Cañas (1999, but we consider that they over-estimated the abundance of muddy facies in the form of lime mudstone, wackestone and packstone. Limestones in all three members are dominantly thick- and massively bedded peloidal grainstones exhibiting tabular and gently undulating bedding. In the lower and upper members there are subordinate ooidal grainstones, along with rare peloidal packstone, intraclastic rudstone, mudstone, microbial laminites and thrombolite patch reefs. Dolostones are of two types: thick- and massively bedded and commonly cher

Basados e [...] n estudios detallados en la sección tipo cercana a Jáchal y siete secciones en el área sur cercana a la ciudad de San Juan, proponemos una subdivisión formal para la Formación La Silla en tres miembros. La división de la unidad está basada en la ubicación preferencial de bancos dolomíticos en el sector central de la Formación mientras que el sector superior e inferior son calizas monótonas. Los miembros se denominan, de base a techo: Miembro Río del Agua, Miembro Río Blanco y Miembro Río Salado (85, 140 y 81 m, respectivamente). Las dolomías en el Miembro Río Blanco son de dos tipos: macizas, potentes y generalmente asociadas a chert; y dolomías con laminación planar y/o entrecruzada, ambas fácilmente distinguibles a simple vista, otorgándole a este Miembro un aspecto bandeado debido a la alternancia entre calizas y dolomías. Esto contrasta con el aspecto macizo y monótono de los Miembros restantes con estratificación tabular y a veces suavemente ondulante. Se reconocen las facies de grainstone peloidal, grainstone oolítico, rudstone intraclástico, packstone peloidal, mudstone, microbiales laminadas y trombolíticas. Además se describen las nuevas facies de dolomías laminadas y dolomías macizas. De la misma manera que lo observado por Keller et al. (1994), la Formación La Silla representa una fase distinta en la sucesión cambro-ordovícica, con las dolomías perimareales de la Formación La Flecha por debajo y las calizas fosilíferas de plataforma abierta de la Formación San Juan por encima. Abstract in english The Cambro-Ordovician carbonate platform succession of the Precordillera Oriental of western Argentina is some 2000 m thick and consists of five formations, from base to top, La Laja, Zonda, La Flecha, La Silla and San Juan (Keller, 1999; Bordonaro, 2003). La Silla Formation (latest Cambrian-Early O [...] rdovician) was defined by Keller et al. (1994) from the lower part of the San Juan Formation. It reaches some 350 m in thickness and consists of a distinctive succession of dominantly light-coloured, poorly fossiliferous limestones. The upper part of La Silla Formation is extensively quarried because of the remarkable purity of the limestones. Based on a detailed study of the type section in the northern outcrop area near Jáchal and seven sections in the southern area near San Juan (Fig. 1a), we propose a formal stratigraphic subdivision of La Silla Formation into three members. These are, from base to top, the Río del Agua Member, Río Blanco Member and Río Salado Member (Fig. 1b), which are 85, 140 and 81 m in their respective type sections. This subdivision is based in the preferential occurrence of creamcoloured dolostones interbedded in the middle part of the formation, whereas the lower and upper members are essentially monotonous limestones. Keller (1999) erected an informal tripartite subdivision conforming to three putative, shallowing-upward sequences, with the boundaries recording abrupt changes in relative sealevel. We do not detect this pattern and our proposed members do not coincide with this subdivision. We recognize nine individual lithofacies types (Fig. 2a-f). These are for the most part similar to those determined by Keller (1999) and Cañas (1999), but we consider that they over-estimated the abundance of muddy facies in the form of lime mudstone, wackestone and packstone. Limestones in all three members are dominantly thick- and massively bedded peloidal grainstones exhibiting tabular and gently undulating bedding. In the lower and upper members there are subordinate ooidal grainstones, along with rare peloidal packstone, intraclastic rudstone, mudstone, microbial laminites

Green area loss in San Juan’s inner-ring suburban neighborhoods: a multidisciplinary approach to analyzing green/gray area dynamics  

Directory of Open Access Journals (Sweden)

Full Text Available The loss of green areas and vegetation in suburban neighborhoods poses short- and long-term consequences associated with environmental changes and socioeconomic decline that can propel such developments to an unsustainable state. We summarize an interdisciplinary investigation aimed at identifying the drivers of green area loss, green cover loss, and quantifying the impact on three inner-ring suburban neighborhoods located along the Rio Piedras watershed in San Juan, Puerto Rico. An inductive approach to social-ecological research was undertaken because it provides a flexible platform for interdisciplinary collaboration on this complex and dynamic subject. The three developments selected for the study were constructed in the mid-20th century under paradigms of modernity that included providing conditions for a better and more dignified way of living, among which green areas played a central role. The green area change analysis was undertaken first, by way of using building footprint growth as a proxy, which represents a minimal estimate of change, and transferring the information from aerial photographs, original development plans, construction drawings, and GIS maps to AutoCAD to quantify building footprint change for each neighborhood. The period of analysis started from the time of the construction of each development to the year 2010. The second estimation was performed using orthorectified infrared aerial imagery to quantify green cover in year 2008 and contrast that information with the conditions at the time the developments were constructed. Green-gray area dynamics were thus analyzed together with longitudinal socioeconomic data to help in the assessment of effects. The investigation revealed long-term socioeconomic declining trends in two of the neighborhoods, weak governance of the built environment, substantial increase in automobile ownership, and distinct physical-spatial characteristics as drivers behind the changes observed. The complexity and variety of exogenous and endogenous factors that have been identified in this study as affecting private and public inner-ring suburban green areas reveals dynamic and spatially differentiated concomitant processes and suggests that these are conditioned by the socioeconomic trajectories of each neighborhood and by larger metropolitan scale socioeconomic and technological trends. Lower income neighborhoods reflect a tendency for socioeconomic decline and greater loss of green areas and vegetation cover in time, thus suggesting policies geared toward adaptive governance. In contrast, the upper income neighborhood exhibits a more stable socioeconomic trajectory and less significant green area loss as well as increase in vegetation cover. Three hypotheses are posited for future sampling increments and testing. The findings and literature on urban economics and the decline of inner-ring suburbs in the U.S. suggest the need for policy geared to sustainable urban redevelopment as a strategy for adaptive governance. The competing needs for land by higher density uses and by green areas in sustainable redevelopment initiatives requires a trade-off analysis in which a thorough account of costs and benefits is warranted. As such, sound data as that presented in this paper will aid urban ecological design in the process of achieving sustainable and environmentally sound land-use adaptations that seek to recuperate green areas’ environmental services in urban and suburban contexts.

Estimation of annual effective dose due to natural radioactive elements in ingestion of foodstuffs in tin mining area of Jos-Plateau, Nigeria  

International Nuclear Information System (INIS)

Soils and food crops from a former tin mining location in a high background radiation area on the Jos-Plateau, Nigeria were collected and analyzed by gamma spectrometry to measure their contents of 40K, 238U and 232Th. As well as collecting samples, in situ dose rates on farms were measured using a precalibrated survey meter. Activity concentrations determined in food crops were compared with the local food derivatives or diets to investigate the possible removal or addition of radionuclides during food preparation by cooking or other means. Potassium-40 was found to contribute the highest activity in all the food products. The activity concentration of 40K, 238U and 232Th in local prepared diets ranged between 60 and 494 Bq kg-1, between BDL and 48 Bq kg-1 and between BDL and 17 Bq kg-1, respectively. The internal effective dose to individuals from the consumption of the food types was estimated on the basis of the measured radionuclide contents in the food crops. It ranged between 0.2 ?Sv y-1 (beans) and 2164 ?Sv y-1 (yam) while the annual external gamma effective dose in the farms due to soil radioactivity ranged between 228 ?Sv and 4065 ?Sv

Molecular identification of Cordylobia anthropophaga Blanchard (Diptera: Calliphoridae larvae collected from dogs (Canis familiaris in Jos South, Plateau State, Nigeria  

Directory of Open Access Journals (Sweden)

Full Text Available Myiasis-causing larvae were extracted from dogs attending veterinary clinics in Plateau State, Nigeria and subjected to molecular analysis involving polymerase chain reaction amplification of the 28S rRNA gene of blowflies, cloning and sequencing techniques. All larvae were confirmed as Cordylobia anthropophaga Blanchard (Diptera: Calliphoridae after the initial morphological identification. This is the first molecular identification of any myiasis-causing fly species in Nigeria and may serve as a reliable alternative to morphological identification where samples are not well preserved or difficult to identify to species level.

El uso de productos del reino mineral en la terapéutica del siglo XVI. El libro de los Medicamentos simples de Juan Fragoso (1581 y el Antidotario de Juan Calvo (1580  

Directory of Open Access Journals (Sweden)

Full Text Available This work aims to approach us the use of "mineral products" in medicine during 16th and 17th centuries. To have an idea about the use of minerals in daily practice, we have studied Juan Fragoso's Libro de los medicamentos simples (1581, and Juan Calvo's Antidotario (1580. We have also checked the presence of these substances in Dioscorides Materia medica, version of Andres Laguna, and the Diccionario de Autoridades. In addition, but not exhaustively, we have followed the used of these products in medicine until the present. This work proves the medical application of about half a hundred of mineral products, the use of which, was coommon in metallurgy, in paintings and vernishes manufacture, in ceramics, in dying industry, etc. However, the physicians of those times, such as Fragoso and Calvo were careful when applying mineral substances due to their great toxicity.

Este trabajo pretende acercamos al uso de lo que podemos designar como productos pertenecientes al reino mineral, en la medicina científica de los siglos XVI y XVII. Con el fin de hacemos una idea de lo que realmente se utilizaba en la práctica cotidiana, se han estudiado el Libro de los medicamentos simples de Juan Fragoso y el Antidotario de Juan Calvo. Tomando como base los fármacos que en ellos se describen y comentan, hemos comprobado su presencia en la versión de la Materia médica de Dioscórides, de Andrés Laguna, y hemos completado la información con las definiciones del Diccionario de Autoridades. Además de esto, aunque no de forma exhaustiva, hemos seguido el empleo de estas sustancias en medicina hasta la actualidad. El trabajo demuestra el empleo en terapéutica de más de medio centenar de este tipo de productos cuyo uso era habitual en metalurgia, en la fabricación de pinturas y barnices, en cerámica, en tintes, etc. Los médicos de entonces fueron bastante cautelosos al aplicarlos debido a su gran toxicidad.

Contributions to the knowledge of the geological evolution of the Atrato and San Juan basins within the arc Panama-Choco  

International Nuclear Information System (INIS)

The geological, geophysical and geochemical data pertaining the previously known as Choco Basin was compiled and reinterpreted. Today, two distinct Cenozoic basins, the Atrato Basin and the San Juan Basin are identified, each with its own geological history. They are bounded by the Istmina-Condoto Structural High, in fact, a paleo-high which intermittently acts as sedimentary barrier, i.e. source area. In the San Juan Delta Basin up to 9 km (?) of mainly clastic sediments were deposited, most probably since Paleocene time. In the Atrato Fore Arc Basin a 10 km thickness of Cenozoic sediments were seismically recorded. Both basins are sufficiently structured, as to produce potential hydrocarbon traps, mainly post-Miocene in age. The tecto-sedimentary framework in the San Juan Basin is controlled by the Istmina-Condoto Fault System in the NW and the Garrapatas Fault System in the SE. In the Atrato Basin the occurrence of growth faults is an outstanding feature.

Seismic Evidence of Abundant Flank Magmatism at the Endeavour Segment, Juan de Fuca Ridge  

Science.gov (United States)

Oceanic crust forms primarily within a narrow, several-kilometer wide, neovolcanic zone at mid-ocean ridges; however, there is an increasing recognition that crustal structure at fast-spreading ridges is modified by off-axis magmatism. Here we use seismic data to show that flank magmatism is also common at an intermediate spreading-rate ridge. We detect several crustal-level, low-velocity, high-attenuation regions on the eastern and western ridge flanks, 7 to 16 km from the neovolcanic zone at the Endeavour segment of the Juan de Fuca Ridge. Seismic refraction data were collected using 64 ocean bottom seismometers (OBSs) and 5,567 airgun shots from the 6600 in3 airgun array of the R/V Marcus G. Langseth in a region extending along the entire ridge segment and out to ~30 km from the rise axis on either side. We observe amplitude anomalies for crustal phases, Pg, for a variety of source-receiver azimuths indicative of numerous anomalous seismic regions on the ridge flanks. We use finite-difference waveform forward modeling to estimate the dimensions, depth, and seismic properties of two of the inferred anomalous regions. The attenuating regions extend horizontally from 2 to 15 km beneath off-axis, ridge-parallel bathymetric highs and from 2 to 4 km below the seafloor. The velocity reduction and the attenuation anomalies suggest the presence of high temperatures and perhaps a small percentage of melt. One anomalous region is associated with a mid-crustal reflector observed in multi-channel seismic data and other mid-crustal reflectors are also present off axis in the region. We attribute the observed seismic anomalies to off-axis magmatic intrusions. Seismic tomography has shown that the upper-crustal, low-velocity layer is thickened on the outer flanks of these highs. This suggests that off-axis volcanism could contribute to the formation of the highs, with erupted lava flowing down the off-axis slopes forming the thicker upper-crustal low-velocity layer. The anomalous zones are found on both the Pacific and Juan de Fuca plates. It is unlikely that the mid-crustal anomalous seismic regions are the result of localized mantle melt delivery from either hotspots associated with the Heck and Heckle seamount chains, or from crustal penetration along lithospheric strike-slip faulting due to a broad shear associated with the Sovanco Fracture Zone, because these effects would predominate on the Pacific flank. We infer that off-axis volcanism at the Endeavour segment is the result of a combination of weak focusing of melt to the ridge axis and of the unique tectonics of this ridge segment that provides conduits for that melt to enter the crust.

/ Application of seismic refraction tomography for tunnel design in Santa Clara Mountain, San Juan, Argentina  

Scientific Electronic Library Online (English)

Full Text Available SciELO Colombia | Language: Spanish Abstract in spanish Se llevó a cabo un estudio geofísico de tomografía sísmica por refracción (SRT) con ondas compresionales en la Sierra de Santa Clara, provincia de San Juan, República Argentina en julio de 2009. El propósito del estudio geofísico fue determinar las variaciones de velocidad de ondas P en el interior [...] del macizo rocoso con el fin de inferir el grado de fracturación y rigidez del mismo, y proyectar la construcción de un túnel vial de 290 m de longitud, que atravesará la montaña de forma casi perpendicular al eje de la misma, a 100 m de profundidad desde la cumbre. Varias dificultades se presentaron desde el punto de vista operativo, que tornaron altamente compleja la realización del trabajo de campo en circunstancias normales. En primer lugar las condiciones topográficas, con pendientes de 45° y profundidades de investigación de 100 m, que implicaba el uso de explosivos para generar ondas sísmicas que alcanzaran los sensores con suficiente relación señal-ruido para distinguirlas. Restricciones legales respecto al uso de explosivos, por una parte, y la potencia insuficiente en caso de uso de golpe de maza por otra, hicieron necesario el diseño y construcción de un cañón impulsado por gas en busca de generar la energía mínima (2 kJ) necesaria para la detección de las señales sísmicas. En segundo lugar, no fue posible la utilización de los métodos convencionales de interpretación que emplean modelos de capas, inoperable en este tipo de estructuras geológicas; por ello resultó imprescindible utilizar el método de tomografìa sísmica que hace uso del concepto de gradientes de velocidades, tanto laterales como en profundidad. Ello posibilitó mapear las variaciones de velocidad en subsuelo en forma de curvas de nivel. Abstract in english A geophysical survey involving seismic refraction tomography (SRT) for mapping 'P' waves was carried out in Sierra Santa Clara, San Juan Province, Argentina in July 2009. The purpose of the geophysical survey was to determine the degree of fracturing and the rigidity of the rock mass through which i [...] t is planned to build a 290 m long road tunnel traversing the mountain almost perpendicular to the axis thereof, at around 100 m depth from the summit. Several difficulties arose from the operational point of view which made it almost impossible to conduct fieldwork in normal circumstances. Firstly, the topography had almost 45° slopes and 100 m research depths which would have involved having had to use explosives to generate seismic waves reaching sensors which had sufficient signal-to-noise ratio for distinguishing them. Legal restrictions regarding the use of explosives on the one hand and insufficient power when using hammer blows on the other made it necessary to design and build a gas-powered gun to achieve the minimum energy (2 kJ) required for detecting seismic signals. Secondly, using conventional interpretation methods involving layered models was inoperable in such geological structures; seismic tomography methods were thus used which make use of the velocity gradient concept (both lateral and in-depth). This allowed mapping subsurface velocity variations in the form of velocity contour lines. The methodology used with the new seismic waves' source generator, as well as SRT application in this type of geological structure, demonstrated that satisfactory results could be obtained for this kind of geophysical study for geotechnical purposes.

Geology and metallogeny of the volcanic complex of Rio Blanco Ullum. Province of San Juan. Republica Argentina  

International Nuclear Information System (INIS)

Preliminary results of a research carried out at the Complejo Rio Blanco de Ullum, San Juan. Argentina are summarized in the present paper. These studies are focused on geological and metallogenic features o f this unit. The study area is located 20 km. WNW of San Juan city with geographic coordinates of 31grades 30' South latitude and 68 grades 52' West longitude. The older rocks aotcroping in the area correspond to limestones of Ordovician San Juan Formation, the chronologic succession continues with sales and siltstones of Silurian Tambolar Formation, pelites and subgraywackes of Devonian Punta Negra Formation and finally a 1500 m thick package of piroclastics and sediments of Albarracin Formation of Tertiary age. Albarracin Formation is composed pf a Basal Member (sandstones and stilstones), a Tuffaceous Member (tuffs, tuffites and oligomictic breccia s with conglomerate interbed dings in the upper part) and a Conglomeratic Member (polimictic para conglomerates). According to piroclastics facies, relationships and spreading area of piroclastics deposits a colapsed dome and avalanche model is proposed to be the main process for the piroclastics package outcropping in the area.Sedimentary and piroclastics rocks are intruded by five sub volcanic units as noted by Leveratto (1968) which are composed by different lithologies such as: Altered Da cite - Rhyolite, Ullum Da cite, Cerro Blanco de Zonda Andesite, Ullum Andesite and Hybrid Andesite.Detailed work onesite and Hybrid Andesite.Detailed work on alteration assemblages and metallogenic features in the southwestern sector of the Complejo resulted in the identification of three alteration zones with characteric features of potassic, argillic and propyllitic signature.

Microbial Primary Productivity in Hydrothermal Vent Chimneys at Middle Valley, Juan de Fuca Ridge  

Science.gov (United States)

Chemosynthetic primary productivity supports hydrothermal vent ecosystems, but the extent of that productivity has not been well measured. To examine the role that environmental temperature plays in controlling carbon fixation rates, and to assess the degree to which microbial community composition, in situ geochemistry, and mineralogy influence carbon fixation, we conducted a series of shipboard incubations across a range of temperatures (4, 25, 50 and 90°C) and at environmentally relevant geochemical conditions using material recovered from three hydrothermal vent chimneys in the Middle Valley hydrothermal vent field (Juan de Fuca Ridge). Net rates of carbon fixation (CFX) were greatest at lower temperatures, and were similar among structures. Rates did not correlate with the mineralogy or the geochemical composition of the high temperature fluids at each chimney. No obvious patterns of association were observed between carbon fixation rates and microbial community composition. Abundance of selected functional genes related to different carbon fixation pathway exhibited striking differences among the three study sites, but did not correlate with rates. Natural carbon isotope ratios implicate the Calvin Benson Bassham Cycle as the dominant mechanism of primary production in these systems, despite the abundance of genes related to other pathways (and presumably some degree of activity). Together these data reveal that primary productivity by endolithic communities does not exhibit much variation among these chimneys, and further reveal that microbial activity cannot easily be related to mineralogical and geochemical assessments that are made at a coarser scale. Indeed, the relationships between carbon fixation rates and community composition/functional gene abundance were also likely obfuscated by differences in scale at which these measurements were made. Regardless, these data reveal the degree to which endolithic, anaerobic carbon fixation contributes to regional primary production, and via modeling reveal the role that this process plays in deep-sea and global carbon cycling.

Microbial diversity within basement fluids of the sediment-buried Juan de Fuca Ridge flank.  

Science.gov (United States)

Despite its immense size, logistical and methodological constraints have largely limited microbiological investigations of the subseafloor basement biosphere. In this study, a unique sampling system was used to collect fluids from the subseafloor basaltic crust via a Circulation Obviation Retrofit Kit (CORK) observatory at Integrated Ocean Drilling Program borehole 1301A, located at a depth of 2667?m in the Pacific Ocean on the eastern flank of the Juan de Fuca Ridge. Here, a fluid delivery line directly accesses a 3.5 million years old basalt-hosted basement aquifer, overlaid by 262?m of sediment, which serves as a barrier to direct exchange with bottom seawater. At an average of 1.2 × 10(4) cells ml(-1), microorganisms in borehole fluids were nearly an order of magnitude less abundant than in surrounding bottom seawater. Ribosomal RNA genes were characterized from basement fluids, providing the first snapshots of microbial community structure using a high-integrity fluid delivery line. Interestingly, microbial communities retrieved from different CORKs (1026B and 1301A) nearly a decade apart shared major community members, consistent with hydrogeological connectivity. However, over three sampling years, the dominant gene clone lineage changed from relatives of Candidatus Desulforudis audaxviator within the bacterial phylum Firmicutes in 2008 to the Miscellaneous Crenarchaeotic Group in 2009 and a lineage within the JTB35 group of Gammaproteobacteria in 2010, and statistically significant variation in microbial community structure was observed. The enumeration of different phylogenetic groups of cells within borehole 1301A fluids supported our observation that the deep subsurface microbial community was temporally dynamic. PMID:22791235

MALÓN, RACIÓN Y NACIÓN EN LAS PAMPAS: EL FACTOR JUAN MANUEL DE ROSAS (1820-1880)

The authors also discuss the historiographic antecedents that assumed a linearly relationship between malón (Indian raids) and cattle trafficking towards Chile, in order to propose the relevance of the rations for the Mapuche economy, understanding them as the governing pact which made possible the formative processes of the provinces and the national states in the pampas since Rosas' period. Documents written by the caciques, their secretaries and the Argentine and Chilean authorities during the nineteenth century will support this hypothesis.

Bathymetry, substrate and circulation in Westcott Bay, San Juan Islands, Washington  

Science.gov (United States)

Nearshore bathymetry, substrate type, and circulation patterns in Westcott Bay, San Juan Islands, Washington, were mapped using two acoustic sonar systems, video and direct sampling of seafloor sediments. The goal of the project was to characterize nearshore habitat and conditions influencing eelgrass (Z. marina) where extensive loss has occurred since 1995. A principal hypothesis for the loss of eelgrass is a recent decrease in light availability for eelgrass growth due to increase in turbidity associated with either an increase in fine sedimentation or biological productivity within the bay. To explore sources for this fine sediment and turbidity, a dual-frequency Biosonics sonar operating at 200 and 430 kHz was used to map seafloor depth, morphology and vegetation along 69 linear kilometers of the bay. The higher frequency 430 kHz system also provided information on particulate concentrations in the water column. A boat-mounted 600 kHz RDI Acoustic Doppler Current Profiler (ADCP) was used to map current velocity and direction and water column backscatter intensity along another 29 km, with select measurements made to characterize variations in circulation with tides. An underwater video camera was deployed to ground-truth acoustic data. Seventy one sediment samples were collected to quantify sediment grain size distributions across Westcott Bay. Sediment samples were analyzed for grain size at the Western Coastal and Marine Geology Team sediment laboratory in Menlo Park, Calif. These data reveal that the seafloor near the entrance to Westcott Bay is rocky with a complex morphology and covered with dense and diverse benthic vegetation. Current velocities were also measured to be highest at the entrance and along a deep channel extending 1 km into the bay. The substrate is increasingly comprised of finer sediments with distance into Westcott Bay where current velocities are lower. This report describes the data collected and preliminary findings of USGS Cruise B-6-07-PS conducted between May 31, 2007 and June 5, 2007.

Variability of fault slip behavior along the San Andreas Fault in the San Juan Bautista Region  

Science.gov (United States)

An improved understanding of the time history of fault slip at depth is an essential step toward understanding the underlying mechanics of the faulting process. Using a waveform cross-correlation approach, we document spatially and temporally varying fault slip along the northernmost creeping section of the San Andreas Fault near San Juan Bautista (SJB), California, by systematically examining spatiotemporal behaviors of characteristically repeating earthquakes (CREs). The spatial distribution of pre-1998 SJB earthquake (1984-1998) fault slip rate inferred from the CREs reveals a ~15 km long low creep or partially locked section located near the 1998 Mw 5.1 SJB earthquake rupture. A finite-fault slip inversion reveals that the rupture of the 1998 SJB earthquake is characterized by the failure of a compact ~4 km2 asperity with a maximum slip of about 90 cm and corresponding peak stress drop of up to 50 MPa, whereas the mean stress drop is about 15 MPa. Following the 1998 earthquake, the CRE activity was significantly increased in a 5-10 km deep zone extending 2-7 km northwest of the main shock, which indicates triggering of substantial aseismic slip. The postseismic slip inferred from the CRE activity primarily propagated to the northwest and released a maximum slip of 9 cm. In this 5-10 km depth range, the estimated postseismic moment release is 8.6 × 1016 N m, which is equivalent to Mw 5.22. The aseismic slip distribution following the 1998 earthquake is not consistent with coseismic stress-driven afterslip but represents a triggered, long-lasting slow earthquake.

Juan Rulfo: Antropología de la Memoria y el estable paisaje de la muerte

Full Text Available Resumen La edificación de un mundo de ficción sobre un mundo real porta algo más que la mera descripción del último, implica, opuestamente, una propuesta de superación o al menos de diferenciación. En el caso de las obras de Rulfo, posibles de ser analizadas en sus connotaciones históricas, sociológicas, políticas, la propuesta del autor parece hablarnos de un estado anterior a toda construcción de comunidad y se refiere a su componente en estado puro, al hombre en su ineludible soledad frente al destino. Recorreremos en esta lectura la dimensión antropológica en busca de especificar qué constituye la realidad del hombre, tanto en el orden natural, tiempo y espacio, como en el sobrenatural, Dios mismo. En el cruce de la horizontal de tiempo y espacio con la vertical de lo divino, intentaremos ubicar al hombre y su destino, situados en el lugar inicial de la memoria. Juan Rulfo: Anthropology of Memory and stable landscape of death Abstract The construction of a fictional world over a real world bears more than a mere description of the latter; it implies, conversely, a proposal for an overcoming or, at least, for a differentiation. In the case of Rulfo´s works, iable to be analyzed in their historical, sociological, political connotations, the author's proposal seems to speak to us of a time before all state of building a community and relates to its component in a pure state, man in his inescapable loneliness against fate. This reading will visit the anthropological dimension in search of specifying what constitutes the reality of man, both in the natural order, time and space, and in the supernatural one, God himself. At the intersection of the horizontal of space and time with the vertical of the divine; we will try to locate man and his destiny in the original memory location.

Noble gas tracing of groundwater/coalbed methane interaction in the San Juan Basin, USA  

Energy Technology Data Exchange (ETDEWEB)

The San Juan Basin natural gas field, located in northwestern New Mexico and southwestern Colorado in the USA, is a case-type coalbed methane system. Groundwater is thought to play a key role in both biogenic methane generation and the CO{sub 2} sequestration potential of coalbed systems. We show here how noble gases can be used to construct a physical model that describes the interaction between the groundwater system and the produced gas. The results conclusively show that the volume of groundwater seen by coal does not play a role in determining the volume of methane produced by secondary biodegradation of these coalbeds. There is no requirement of continuous groundwater flow for renewing the microbes or nutrient components. Strong mass related isotopic fractionation of {sup 20}Ne/{sup 22}NE and {sup 38}Ar/{sup 36} isotopic ratios was also seen. This can be explained by a noble gas concentration gradient in the groundwater during gas production, which causes diffusive partial re-equilibration of the noble gas isotopes. It is important for the study of other systems in which extensive groundwater degassing may have occurred to recognize that severe isotopic fractionation of air-derived noble gases can occur when such concentration gradients are established during gas production. Excess air-derived Xe and Kr in our samples are shown to be related to the diluting coalbed methane and can only be accounted for if Xe and Kr are preferentially and volumetrically trapped within the coal matrix and released during biodegradation to form CH{sub 4}.

Mountain system monitoring at Senator Beck Basin, San Juan Mountains, Colorado  

Science.gov (United States)

Alpine mountain systems exhibit particular sensitivity to climate change in the form of altered patterns in plant communities, snowcover and hydrologic characteristics, biogeochemical fluxes, and energy budgets. Monitoring of such systems, across elevational gradients, and using an integrative approach, could yield early evidence of long-term trends in local and regional mountain processes and the ecological and economic services they provide. Climate change and ecological modelers can also eventually benefit from field verification of their forecasts. To these ends, the Senator Beck Basin Study Area has been developed in the western San Juan Mountains, a high altitude, mid-latitude, continental mountain range located in southwest Colorado, USA. This 290 ha 'headwater' catchment spans elevations from 3353 to 4118 m, a gradient that captures alpine (arctic-like) tundra at the highest elevations, sub-alpine forest at the lowest, and the dynamic krumholz ecotone between. Seasonal snowcover dominates this landscape for up to nine months per year, and monitoring and research infrastructure has been conceived and developed to capture this (mountain) snow system's behaviors. Two extensive arrays of instrumentation monitor weather, snowpack, energy budget, and basic soil condition parameters. A stream gauge at the basin pour point monitors streamflow and basic water properties. Routine snow profiles monitor snowpack properties adjacent to the micro-met sites. And, a comprehensive inventory of the basin's plant communities was performed in 2004, at three elevational bands, and field monuments were installed to facilitate routine repeat studies. Significantly different populations and degrees of diversity were found at each elevational band. Researchers currently being hosted in the basin are exploring the effects of desert dust depositions on alpine snowpack, hydrologic, biogeochemical, and climatic processes, at multiple spatio-temporal scales. Comparable integrative research projects utilizing the Senator Beck Basin Study Area are encouraged, and collaborators are sought for the continued development of an integrated monitoring and research program supporting investigations of interactions driving, being driven by, and otherwise comprising the mountain (snow) system.

Fen Wetland Hydrology and Constraints on the Fate and Transport of Heavy Metals in the San Juan Mountains, Colorado  

Science.gov (United States)

The interactions of a variety of geomorphic processes and a complex geology have produced spectacular landscapes throughout the San Juan Mountains. This complex geology abounds in mineral deposits that were mined from the mid 1800s through the 1990s. Unfortunately, much of this early mining impacted the streams, lakes, groundwater, and fens in this environment. Today, mining is waning and interest in restoration of this alpine environment is growing. Thus, sustainable restoration requires understanding dynamic interactions in this environment, which mandates an evaluation of the geomorphic and hydrologic processes that shape the present landscape. Fen wetlands, which have developed in geologic niches produced by the intense glaciation of the San Juans, occur throughout the area. The San Juans primarily exhibit a radial drainage pattern, which continue to feed the wetlands. The hydrology of these wetlands controls the chemical and biological processes and may be the most important factor regulating fen wetland function and development. Hydrological models can be used to simulate these processes and to evaluate management scenarios for fen restoration. Five fens, located along glaciated valley floors at elevations of greater than 3,000 m, range in area from 0.4 km2 to 0.7 km2. These fens were compared to determine the influence of their morphometry on runoff and evapotranspiration. The fen hydrology is dominated by irregularly located and poorly linked pools. We are attempting to combine saturated-unsaturated groundwater flow and transport models to study each fen. Hydrological conditions within the fens, which act as a sink or filter for heavy metals, also play a major role in determining the fate of transport of contaminants associated with prior mining activities. Indeed, preliminary studies have found higher than normal concentrations of aluminum, cadmium, copper, iron, manganese, and zinc occurring throughout the San Juan wetlands. Lead is also thought to occur in high concentrations, but less is known about exact levels of lead, and how various competing contaminant sources contribute to its deposition. Mining was prevalent in this area in the late nineteenth century, thus the five fens studied here have a range in contamination history due to proximity of each fen to past mining activities. Heavy metal concentration and Pb isotope ratio profiles (~35-cm depths) were measured at high resolution (2-cm intervals). The profiles provide a history of the fate and transport of the various heavy metal contaminants and, together with the hydrologic transport model, will help guide management scenarios for future restoration.

Geochemical data from waters in Prospect Gulch, San Juan County, Colorado, that span pre- and post-Lark Mine remediation  

Science.gov (United States)

In San Juan County, Colorado, the effects of historical mining continue to contribute dissolved metals to groundwater and surface water. Water samples in Prospect Gulch near Silverton, Colorado, were collected at selected locations that span pre- and post-reclamation activities at the Lark Mine, located in the Prospect Gulch watershed. Geochemical results from those water samples are presented in this report. Water samples were analyzed for specific conductance, pH, temperature, and dissolved oxygen with handheld field meters, and metals were analyzed using inductively coupled plasma-mass spectrometry.

Full Text Available SciELO Chile | Language: Spanish Abstract in spanish Los parrales, los braceros y las cepas de cabeza fueron las tres modalidades más utilizadas para el cultivo de la vid en Mendoza y San Juan, desde la fundación de la capital de la provincia de Cuyo del Reino de Chile por los conquistadores españoles (1561) hasta la modernización y el afrancesamiento [...] de la viticultura argentina, en la década de 1870. El tema es relevante porque Argentina es actualmente la mayor potencia vitivinícola de América Latina y la quinta del mundo. El trabajo se ha realizado a partir de fuentes originales de los archivos de las ciudades de Mendoza, San Juan y Santiago de Chile, con el procesamiento de más de 400 mil datos sobre viñas, parrales y cepas. En el estudio se detectó que el 97% de las cepas se cultivaban en viñas y el solo 3% en parrales encatrados. Dentro de las primeras, el cultivo de las tres cuartas partes se hacía mediante el sistema en vaso, gobelet o cepas de cabeza (como se llamaba en América), mientras que el cuarto restante era embracerado: los sarmientos se conducían con varillas de sauce y álamo. Por lo general, las variedades de uva negra se cultivaban en cepas de cabeza y los moscateles en bracero o parrales encatrados. Abstract in english Parrales, braceros and gobelet were the three most utilized methods to cultivate grapevines in Mendoza and San Juan, since the founding of the capital of Cuyo Province in Chile´s Reign. These methods prevailed from the Spanish conquest of the area, in 1561, until the impact of French-like methods in [...] Argentina’s vine-growing in the 1870s. This topic is relevant because Argentina is today the main wine producer in Latin America and the fifth largest producer in the world. This work has been prepared based on original sources from archives located in Mendoza, San Juan and Santiago, with the processing of more than 400,000 data regarding vineyards, vines and stocks of wine. This study demonstrates that 97 percent of the stocks of wine were cultivated in vineyards and only 3 percent by using parrales encatrados. Among the former, three fourths used the sistema de vaso, gobelet or cepas de cabeza, as it was called in America; The rest used an embracerado system, where vine shoots were led with willow and poplar sticks. In general, black grapes were cultivated with cepas de cabeza and muscatel wine using the bracero or parral encatrado system.

Numerical study of the storm-induced circulation on the Scotian Shelf during Hurricane Juan using a nested-grid ocean model  

OpenAIRE

A nested-grid ocean circulation modelling system is used to assess the upper ocean response of the Scotian Shelf and adjacent slope to Hurricane Juan in September 2003. The nested-grid system consists of a fine-grid inner model covering the Scotian Shelf/slope and a coarse-grid outer model covering the northwest Atlantic Ocean. The model-calculated upper ocean response to Hurricane Juan is characterized by large divergent surface currents forced by the local wind forcing under the storm, and ...
