    Full Text Available En el presente artículo son reportados ejemplares de diversos taxones de reptiles escamados fósiles procedentes de la base de la Formación Luján (Pleistoceno Superior, en la localidad fosilífera de Merlo, provincia de Buenos Aires, Argentina. Entre los ejemplares registrados se reconoce el primer registro fósil para el género y especie Anops kingii (Amphisbaenidae; asimismo se reporta la presencia de especies indeterminadas de los géneros Homonota (Gekkonidae y Liolaemus (Liolaemidae. La asociación conjunta de estos tres taxones hoy en día no se encuentra representada en el norte de la provincia de Buenos Aires, siendo la región geográficamente más cercana en donde encuentran una superposición en su distribución el Partido de Balcarce, ubicado en el extremo Sureste de la provincia y alejado unos 600 kilómetros al sur de la localidad fosilífera de Merlo. La presencia conjunta de estos tres reptiles se encuentra de acuerdo con la posible existencia de un pulso árido y frío, tal como ha sido propuesto con anterioridad para porción más inferior del Pleistoceno Superior en la provincia de Buenos Aires.

    Full Text Available Eight formations are identified in carbonate platform series of upper Cretaceous age (upper Albian-lower Campanian in Yecla region (Prebetic palaeogeographic setting, Murcia province, SE Spain. Their stratigraphical and sedimentological analysis allows to differenciate two depositional megasequences with their internal divisions and evolutionary trends, and then to compare them with those of the Iberian Cordillera. The major patterns of both basin evolutions are suprabasinal. In prebetic pasive margin, the first megasequence (of upper Albian-upper Cenomanian pro parte age is controlled by eustatism, great subsidence and sinsedimentary tectonics. The second (uppermost Cenomanian-lower Campanian, characterized by a greater stability, is strongly controlled by Iberian Plate geodinamics. On the other hand, biostratigraphic data permits, by once, to date upper Cenomanian platform sediments in Prebetic area, and to questionate about Turonian existence.En las series carbonáticas del Cretácico superior (Albiense sup.-Campaniense inf. del sector septentrional de Yecla (Prebético, Murcia se delimitan, sobre la fm.

Contrario a lo sugerido previamente, la morfología dental de UC posee un sorprendente parecido con el patrón sundadonte típico del sudeste de Asia. Gráficos de dispersión usando un análisis de componentes principales (ACP ubican a UC cerca de otras poblaciones relacionadas con el sudeste de Asia indicando una afinidad sundadonte. Un análisis de distancias biológicas usando la distancia euclidiana al cuadrado (DE seguida de una prueba de escalamiento multidimensional (MDS produjo resultados muy similares. Una comparación entre UC y varias muestras sinodontes de las Américas no soporta el concepto de una afinidad cercana, producto de un supuesto origen común. Previos estudios sobre una posible relación entre el Asia Sudoriental y Sudamérica se ven corroborados en este estudio, debido a la notable afinidad existente entre diferentes muestras dentales de Sudamérica, Asia Sudoriental y los homínidos de UC. La afinidad sundadonte de la muestra de Zhoukoudian detectada en este análisis sugiere que las siguientes hipótesis deben reevaluarse: 1 UC se derivan de una antigua población sinodonte en el noreste de Asia. 2 Hace poco más de 30 Ka sundadonte evolucionó hacia sinodonte en el norte de China, Mongolia y/o el sur de Siberia. 3 Existe una continuidad sinodonte desde Zhoukoudian (34. Ka hasta Dawenkou (6. Ka en el norte de China. 4 Dado que UC posee características dentales sinodontes, debe presentar una estrecha relación con poblaciones recientes del noreste de Asia y todos los nativos americanos pasados y presentes. Finalmente estos hallazgos contradicen el modelo de evolución local o de continuidad morfológico-regional para la historia poblacional del este de Asia y además sugieren que al menos una parte de los nativos

  10. The Medical Vocabulario terminológico of Manuel Hurtado de Mendoza

    Directory of Open Access Journals (Sweden)

    Bertha M. Gutiérrez Rodilla

    2012-12-01

    Full Text Available From the early nineteenth century, Spanish physicians started to sense a «threat» to the language of medicine which they used, due in part to the large number of foreign terms they were forced to import from other languages, particularly French. Many voices emerged to denounce this situation and propose potential solutions such as those which would be derived from the creation of a terminological dictionary which would fix precise meanings for medical terms. It was Manuel Hurtado de Mendoza who eventually dared to take on this task and develop the first modern terminological dictionary of medicine in Spanish. The intention of this paper is to present from a philological viewpoint the process by which a lexicographical work that deserves to be better known and used in studies on historical lexicography came to be constructed.

    The figure of Manuel Hurtado de Mendoza has been sufficiently analyzed in connection with his contributions to Spanish anatomy during the first half of the 19th century or to the introduction of some European innovations in Spain. However, there is still much of his work to be studied, such as the medical dictionaries he wrote, two encyclopedic and one terminological. We deal with the first two in this essay, where we will speak highly of his significance in an age in which specialized lexico...

    2005-01-01

    Full Text Available Cuando a fines de 1941 el Padre Alberto Hurtado publicó su libro "¿Es Chile un País Católico?", invitaba especialmente a los jóvenes de la Acción Católica a conocer el país real: ¿cómo era de verdad Chile y su Iglesia? Alberto Hurtado con su mirada de apóstol miró a Chile desde la mirada de Jesús y remeció conciencias e incomodó a muchos con su denuncia de los males que corroían el alma nacional: miseria, injusticias, vicios, salarios miserables, falta de educación del pueblo, viviendas indignas, y junto con esto, la lejanía de los pobres de la Iglesia y la escasez de sacerdotes. Para él había una tarea pendiente que muchos esquivaban: conquistar Chile para Cristo. El libro y la invitación fueron acogidos con gran entusiasmo, por los jóvenes especialmente; pero las cr��ticas arreciaron de parte del clero y laicado conservadores. Para ellos, la visión de Hurtado era peligrosamente amarga y desconocía la labor que la Iglesia, desde la Colonia, hacía en el país formando el "alma de Chile". La polémica de fondo era una sorda crítica a Hurtado, asesor nacional de los jóvenes de la Acción Católica. El artículo muestra la polémica en torno al libro y a su autor, los diferentes actores que intervinieron y la significación eclesial de todo el proceso: ¿Era Chile un país católico?When at the end of 1941 Father Alberto Hurtado Publisher his book, "¿Es Chile un País Católico?" ("Is Chile a Catholic Country?", he especially invited the youth of Catholic Action (Acción Católica to become acquainted with the real country: What was Chile and its Church really like? Alberto Hurtado, with his characteristic view of an apostle, looked upon Chile with the gaze of Jesus and shook consciences, making many people uncomfortable with his condemnation of the evils corroding the national soul: the misery, injustices, vices, paltry salaries, lack of education, undignified living conditions and, together with all this, the

    Full Text Available : La teología del Cuerpo Místico de Cristo ocupó un lugar central en el pensamiento de san Alberto Hurtado. En las distintas etapas de su vida desarrolló una antropología a partir del Cuerpo Místico: el hombre está llamado a ser hijo de Dios, basta ser hombre para poder pertenecer al Cuerpo Místico, Cristo está presente en los pobres y la unidad de todos los hombres en Cristo. Este estudio muestra la influencia de Columba Marmión en nuestro autor. Esta antropología teológica es el fundamento de su moral social: la dignidad de la persona humana está fundamentada en la encarnación del Verbo. La opción por los pobres y la solidaridad social son parte de la ética social que el padre Hurtado ha fundamento con su teología del Cuerpo Místico de Cristo.The theology of the Christ Mystical Body has occupied a principal place in St. Alberto Hurtado's thought. He developed an anthropology from the Mystical Body in the different moments of his life: the man is called to be a children of God, that is enough to be a man to be able to belong at de Mystical Body, that Christ is present in the poors, and the unity of all men in Christ. This investigation shows the influence of Columba Marmión in our author. The theological anthropology is the foundation of his social morality: the dignity of human person is based in the incarnation of the Word. The option for the poors and social solidarity are part of the social ethics that padre Hurtado has based with his theology of the Christ Mystical Body.

El viaje le permite, además, tomar contacto con diversas obras sociales de la Iglesia de EE. UU y de Canadá, profundizar su estudio en la doctrina social de la Iglesia y sus aplicaciones prácticas, y proyectar dos de sus obras sociales más conocidas: el Hogar de Cristo y la ASICH. Finalmente, el contacto con uno de los países más desarrollados del mundo, le inspira en su ministerio sacerdotal a predicar que «la materia no basta» y la centralidad de «la visión de fe».This article shows the impact and the consequences of St. Alberto Hurta-do's trip to the United States in 1945. Access to new documents has shed further light on the reasons for the trip: after he renounced the Catholic Action, Mons.

The trip also allows him to get involved in several social works of the U.S. and Canadian Church, deepen his study of the Church's social doctrine and its practical applications, and plan two of his best-known social works: Hogar de Cristo and ASICH. Finally, contact with one of the world's most developed countries inspires him in his priestly ministry to preach that «what is material is not enough» and the centrality of the «vision of faith».

Una de las variables importantes a considerar en el análisis de los perfiles de los estudiantes universitarios son sus expectativas académicas, ya que están asociadas a diferentes niveles de implicación, permanencia y éxito académico. Tomando una muestra de 717 estudiantes de 1º año, portugueses y españoles, se aplicó un cuestionario de expectativas que contempla siete dimensiones: i Formación empleo/carrera; ii Desarrollo personal y social; iii Movilidad internacional; iv Implicación política y ciudadanía; v Presión social; vi Calidad de formación; e vii Interacción social. Los resultados fueron analizados en función del país, sexo y de ser o no estudiante de 1º generación (si ninguno de los padres tiene estudios de ES. Los análisis muestran que, de forma general, los estudiantes españoles presentan expectativas más bajas que los estudiantes portugueses. Por otro lado, se observa un efecto en sentido inverso entre ser o no estudiante de primera generación, de modo que los estudiantes portugueses cuyos padres tienen estudios de Enseñanza Superior presentan expectativas más elevadas, produciéndose una situación inversa en los estudiantes españoles.

    Full Text Available En la línea de las investigaciones desarrolladas sobre la contabilidad de las instituciones eclesiásticas en España, este trabajo estudia la que en el siglo XVI fue considerada la sede más rica de la Cristiandad después de Roma, la Catedral de Toledo. Su elevado estatus pudo ser una cuestión significativa para influir en el proceso de desarrollo de su sistema de gestión y en la adopción de prácticas contables novedosas. Además, dentro de la catedral existían beneficiados con aptitudes para dar solución a cualquier cuestión económica. Más concretamente, uno de ellos, el racionero Gutierre Hurtado, fue el autor de la primera muestra de contabilidad por partida doble en la catedral de Toledo y la primera muestra conocida, hoy por hoy, en el mundo para una entidad eclesiástica. En este trabajo se muestran algunos fragmentos sobre su vida y cometido; y los aspectos generales y especiales que caracterizan el método contable usado por este racionero. Para ello, examinaremos los documentos que se conservan en el Archivo de la Catedral de Toledo Palabras clave: Contabilidad eclesiástica, partida doble, catedral de Toledo.Through an approach close to the research of the studies on accounting of the religious organizations in Spain, this paper intends to study an entity that was considered the richest see of Christendom after Rome in the 16th century, the Cathedral of Toledo.

    Full Text Available El trabajo ref lexiona sobre el abasto de agua potable en los municipios fronterizos del norte de Tamaulipas, a partir de la perspectiva del derecho humano al agua ( DHA . Se responde la pregunta: ¿cómo se ha desarrollado la cobertura de agua potable en esos municipios? Se revisan estadísticas del Inegi de 1990 a 2010, ejemplares del Periódico o f icial del estado y diversas fuen - tes secundarias. Se encuentra que hay coberturas altas, tanto en agua potable como en drenaje, superiores a los promedios nacional y regional. Sin embargo, aún existe población sin acceso a estos servicios en sus viviendas y que, utilizando el DHA como una herramienta de gestión, puede demandar la dotación de esos servicios.

Secuencias de un paleomargen pasivo septentrional (PPS; 2. El cinturón ofiolítico septentrional (COS; 3. El terreno de arcos volcánicos cretácicos (TAVK, y 4. Secuencias metamorfizadas de un paleomargen pasivo meridional (PPM. Tres tipos de cortes de secuencias de margen pasivo, geográficamente bien diferenciados, afloran en el norte de Cuba: A-Cortes de Guaniguanico, divisibles a su vez en tres subtipos: Sierra del Rosario, Sierra de los Órganos y Cinturón Cangre; B-Cortes del norte de Cuba Central, caracterizados por una manifiesta zonalidad estratigráfica y estructural, y C-Cortes de Maisí, caracterizados poe el metamorfismo de bajo grado de sus rocas. En estas tres regiones los cortes más jóvenes, comenzando en el Jurásico Superior, son casi exclusivamente carbonatados, mientras que su parte inferior (Oxfordiano y más antiguo es terrígena, exceptuando los más septentrionales, en Cuba central, donde están presentes evaporitas. Los cortes A y B presentan una discordancia qie se correlaciona estrechamente con el Mid-Cretaceous Sequence Boundary, detectado en el sur del golfo de México y el estrecho de La Florida. Las similitudes, en particular entre las regiones A y B, indican una misma identidad geológica. Su posición actual, yuxtapuestos a las plataformas de Bahamas y Yucatán de la placa norteamericana, y su bien confirmado tránsito a los cortes de Bahamas en el norte de Cuba central, indican que los cortes del PPS deben formar parte del margen pasivo mesozoico de la América del Norte. La continuación al este de los cortes de Guaniguanico es visible en varios afloramientos y registrada por numerosos pozos de prospección desde el oeste de La Habana hasta Matanzas. Por tanto, no hay razón para considerar los cortes de Guaniguanico como parte de los "terrenos sudoccidentales". Siguiendo esta

La problemática de la investigación indaga la movilidad estudiantil que por múltiples factores, afecta y vulnera el derecho a la educación en esta área geográfica. El objetivo propuesto busca comprender la dinámica de la movilidad estudiantil en el eje Táchira-Norte de Santander, para generar propuestas que fortalezcan una política educativa fundamentada en la condición de frontera y de integración binacional. La investigación muestra un diagnóstico, a partir de una metodología cuanticualitativa, con fuentes estadísticas, institucionales y trabajo de campo. Entre los hallazgos está, el uso consuetudinario de la doble identidad, como medio para saltar los requerimientos oficiales de inmigración, y acceder así a la educación, hecho que posteriormente se convierte en obstáculo de la misma movilidad estudiantil.

    Full Text Available Los miembros del equipo de cooperación internacional "Territorio Andaluz, Desarrollo e Innovación" se han implicado durante más de una década en proyectos de desarrollo sobre zonas colindantes con el Estrecho de Gibraltar. En este artículo se resume el perfil y las conclusiones obtenidas en los proyectos de cooperación desarrollados por el grupo, así como otros hechos relacionados con las transformaciones territoriales del Norte de Marruecos. En la actualidad, las acciones se basan en la construcción de grandes puertos y carreteras cercanas a los nuevos centros turísticos de la costa. Los impactos son evidentes en el medio ambiente y en el contexto social. La transformación radical ha aumentado el atractivo en las zonas urbanas, incrementando el éxodo rural que ya era de por sí considerable. Por otra, la pérdida de calidad de vida la asociamos a la merma de suelo cultivable y el deterioro del medio al poner en cultivo tierras forestales. La agricultura es de subsistencia y como tal está sometida a la supervivencia de las familias en un medio cada vez más desfavorable. Las intervenciones en este medio podrían tomar como ejemplo los patrones que se han aplicado en el entorno rural español en el pasado, cuyo deterioro siguió pautas similares en un período de tiempo más largo.

    Full Text Available Las brechas tecnológicas entre países y regiones son la pieza clave en la diferenciación económica y en las tasas de crecimiento resultantes. Los países y regiones menos desarrollados pueden fomentar competencias tecnológicas con estrategias diferentes. El mejor momento para que este tipo de países ingrese en la competencia por el control tecnológico es cuando las tecnologías y los conocimientos relacionados con ellas están en una etapa inicial, a lo que se le conoce como ventana de oportunidad tecnológica y locacional. En este artículo, se argumenta que la ventana de oportunidad de la biotecnología aún está abierta, y que México todavía puede entrar en la competencia mundial por su desarrollo. No obstante lo anterior, se documenta que Canadá y Estados Unidos están generando ventajas absolutas con rapidez, por lo que las ventanas de oportunidad en algunas áreas pronto estarán "cerradas". Se presentan las regiones que dominan la creación de aplicaciones comerciales en biotecnología en la región de América del Norte. En particular, se subraya el papel destacado que algunas ciudades canadienses están jugando en el desarrollo de esta industria, pese a la competencia estadounidense.

  4. Superiorization with level control

    The convex feasibility problem is to find a common point of a finite family of closed convex subsets. In many applications one requires something more, namely finding a common point of closed convex subsets which minimizes a continuous convex function. The latter requirement leads to an application of the superiorization methodology which is actually settled between methods for convex feasibility problem and the convex constrained minimization. Inspired by the superiorization idea we introduce a method which sequentially applies a long-step algorithm for a sequence of convex feasibility problems; the method employs quasi-nonexpansive operators as well as subgradient projections with level control and does not require evaluation of the metric projection. We replace a perturbation of the iterations (applied in the superiorization methodology) by a perturbation of the current level in minimizing the objective function. We consider the method in the Euclidean space in order to guarantee the strong convergence, although the method is well defined in a Hilbert space.

    Evaporation is a critical component of the water balance of each of the Laurentian Great Lakes, and understanding the magnitude and physical controls of evaporative water losses are important for several reasons. Recently, low water levels in Lakes Superior and Michigan/Huron have had socioeconomic, ecological, and even meteorological impacts (e.g. water quality and quantity, transportation, invasive species, recreation, etc.). The recent low water levels may be due to increased evaporation, but this is not known as operational evaporation estimates are currently calculated as the residual of water or heat budgets. Perhaps surprisingly, almost nothing is known about evaporation dynamics from Lake Superior and few direct measurements of evaporation have been made from any of the Laurentian Great Lakes. This research is the first to attempt to directly measure evaporation from Lake Superior by deploying eddy covariance instrumentation. Results of evaporation rates, their patterns and controlling mechanisms will be presented. The direct measurements of evaporation are used with concurrent satellite and climate model data to extrapolate evaporation measurements across the entire lake. This knowledge could improve predictions of how climate change may impact the lake's water budget and subsequently how the water in the lake is managed.

    The Lake Superior fish community has changed substantially since the early 1960s, when control of the sea lamprey (Petromyzon marinus) became effective. Self-reproducing stocks of lake trout (Salvelinus namaycush) have been reestablished in many inshore areas, although they have not yet reached pre-sea lamprey abundance; offshore lake trout are probably at or near pre-sea lamprey abundance. Stocks of lake whitefish (Coregonus clupeaformis) appear to have fully recovered; commercial catches are at or above historical levels. Lake herring (Coregonus artedii) are recovering rapidly in U.S. waters and are abundant in western Canadian waters. The population of rainbow smelt (Osmerus mordax), which declined in the 1970s, is recovering. Pacific salmon (Oncorhynchus) are becoming more abundant as a result of increased stocking in U.S. waters and are reproducing in most suitable tributaries; they have become significant in anglers' creels.

    Full Text Available La construcción de la frontera política administrativa, a mediados del siglo diecinueve, entre Arizona (Estados Unidos y Sonora (México provocó una dispersión entre los pápagos que quedaron al lado mexicano y los que se ubicaron al norte de la línea fronteriza. Durante años esta división generó un alejamiento en los estilos de vida y en la forma de habitar un ambiente desértico; en la actualidad, la frontera política se expresa en las esferas de la vida social, económica y cultural. En este artículo se hace referencia a la situación de los pápagos, la "gente del desierto" que habita el desierto de Altar, al norte de Sonora, quienes actualizan sus referentes comunes para identificarse como etnia y como grupo.

    Full Text Available En este trabajo se realiza una discusión sobre la aplicabilidad de la propuesta de la denominada corriente regulacionista en torno a la espacialidad de los procesos recientes de industrialización, para un caso dentro de los países no centrales, en particular sobre el proceso de industrialización ocurrido en la Frontera Norte mexicana, desde mediados de la década pasada. Lo que se cuestiona, primeramente, a nivel teórico, es la utilidad de esta propuesta para parte de los estados no-centrales del Sistema Mundial. También se desarrollan, en el mismo plano, las objeciones principales en relación a sus supuestos generales al aplicarse esta teoría tanto al centro del Sistema Mundial como también al resto de ésta. Las características principales de este reciente proceso de industrialización en el territorio del norte mexicano son esbozadas para luego ser confrontadas a los supuestos subyacentes a la teoría regulacionista. Desde la crítica formulada a esta escuela de pensamiento, se genera una propuesta interpretativa, basada primeramente sobre el concepto de espacio de flujos, y después sobre la flexibilidad en el uso de la región fronteriza del norte mexicanoA debate is proposed in this paper on the suitability of the regulationist proposal to explain the spatial implications of recent industrial processes. This suitability is questioned for a particular territory in a non-central Nation-State, the Mexican Northern Border, from the mid-dle 1980´s. At a theoretical level, the usefulness of this for parts of the non-central nations of the World-System. On the same level the main objections on its general assumptions when this theory is applied to the center of the World-System as well as to the rest of it.

Spanning the US-Mexico border; the coalition includes stakeholders from El Paso, Texas; Ciudad Juarez, Mexico; and Las Cruces, New Mexico. PDNCCC developed a comprehensive plan to jump-start its program place, alternative fuel vehicles (AFVs) on the road, and eliminate barriers inhibiting alternative fuel market growth. PDNCC raised more than $2.3 million for alternative fuel activities and clean air initiatives in less than 26 months. In 1998, the US Department of Energy (DOE) recognized that PDNCCC accomplishment with its Rainmaker Award for leveraging the most funds from outside sources. PDNCCC is proud of its efforts to drive the alternative fuels and AFV market in the El Paso/Juarez region.

  7. Ozone studies in the Paso del Norte region

    Science.gov (United States)

    Becerra-Davila, Fernando

    The Paso del Norte region forms the largest contiguous bi-national conglomerate on the US-Mexico border. With a combined population of around 2 million inhabitants, the Paso del Norte region is isolated, more than 500 km away from the nearest urban area of comparable size, thus making it an ideal location for air quality studies of an isolated urban environment. The meteorological conditions leading to a high ozone episode in this region, such as the historical ozone episode of June 2006, are analyzed. It is well known that stagnation and minimal winds, high temperatures, and pressure ridges over the region are conducive to high ozone episodes. In addition, the planetary boundary height is studied to understand its impact on high ozone episodes. Several studies report that ground level ozone non-attainment regulations could be caused not only by local emissions, but also by atmospheric transport. In this work the atmospheric advection of pollutants into the region is analyzed using HYSPLIT backward trajectories. Furthermore, a novel backward trajectory clustering technique is implemented for the summer of 2006. The "ozone weekend effect" (OWE) is a phenomenon by which in some geographical regions ambient ozone concentrations tend to be higher on weekends than on weekdays, despite the lower emissions of ozone precursors during those days. The observed local OWE has never previously been studied in terms of the photolysis rates of four of the main ozone precursors. In this research a novel method that allows the calculation of actinic fluxes, photolysis frequencies and photolysis rates with a high degree of accuracy and reliability has been developed. This method utilizes a combination of the experimental data available for this region in conjunction with a radiative transfer model (TUV model). Three weekend-weekday cases during summers 2006, 2009 and 2010 are studied in this work. In this research, the photolysis impact on the local OWE is studied. The results

    Emission inventories of ozone precursors are routinely used as input to comprehensive photochemical air quality models. Photochemical model performance and the development of effective control strategies rely on the accuracy and representativeness of an underlying emission inventory. This paper describes the tasks undertaken to compile and evaluate an ozone precursor emission inventory for the El Paso/Ciudad Juarez/Southern Dona Ana region. Point, area and mobile source emission data were obtained from local government agencies and were spatially and temporally allocated to a gridded domain using region-specific demographic and land-cover information. The inventory was then processed using the US Environmental Protection Agency (EPA) recommended Emissions Preprocessor System 2.0 (UAM-EPS 2.0) which generates emissions files compatible with the Urban Airshed Model (UAM). A top-down evaluation of the emission inventory was performed to examine how well the inventory represented ambient pollutant compositions. The top-down evaluation methodology employed in this study compares emission inventory ratios of non-methane hydrocarbon (NMHC)/nitrogen oxide (NO{sub x}) and carbon monoxide (CO)/NO{sub x} ratios to corresponding ambient ratios. Detailed NMHC species comparisons were made in order to investigate the relative composition of individual hydrocarbon species in the emission inventory and in the ambient data. The emission inventory compiled during this effort has since been used to model ozone in the Paso del Norte airshed (Emery et al., CAMx modeling of ozone and carbon monoxide in the Paso del Norte airshed.

    Full Text Available El artículo analiza tres movimientos laborales en las maquiladoras de la frontera norte, acontecidos entre 1997 y 1998, señalando que más que eventos coyunturales, tales manifestaciones son parte de la reestructuración sindical iniciada en estas empresas durante los años setenta y ochenta. El comienzo de este proceso estuvo caracterizado por una definición de la función y los objetivos que estas organizaciones deberían desempeñar en estas industrias; así se conformaron dos comportamientos: el sindicalismo tradicional, vinculado a los trabajadores, y el sindicalismo subordinado, enlazado a los inversionistas. La segunda fase, iniciada a principios de los noventa, se ha caracterizado por un reacomodo en las estructuras internas de las organizaciones sindicales locales. En este reacomodo, la fragilidad de algunas organizaciones conformadas ex-profeso para las maquiladoras, como lo muestran los conflictos analizados, ha sido evidente.

    Full Text Available The Ecological Solid Waste Management Act of 2000 or RA 9003 mandates the local government units to take initiatives in managing their daunting problems on ecological solid waste disposal. Consequently, compliance of Camarines Norte, Philippines on this mandate needs assessment to determine the existing solid waste management (SWM strategies, the effectiveness and the possibility of adoption in each municipality. This study utilized the descriptive method using questionnaire as the main tool supplemented by interview. Results showed that the existing SWM strategies with the highest percentages of existence in the twelve (12 municipalities were provision of number of trucks in transporting solid wastes and knowledge on waste segregation conducted at every household/establishment. Varying levels were observed. However, high level of effectiveness is still required for significant impact, seeing that from the six areas assessed only four municipalities were identified to have more and highly effective SWM strategies. Generally, only availability of technology for composting was considered more effective and can be adopted in all municipalities. Better solid waste management may be fully attained through the involvement, political will and commitment of the implementers in the implementation of politically passed resolutions and undertaking of their initiatives that will stimulate active participation of the community. All these measures may bring change in health and environment in the province.

    Full Text Available The prosopomorphic vessels from Moesia Superior had the form of beakers varying in outline but similar in size. They were wheel-thrown, mould-made or manufactured by using a combination of wheel-throwing and mould-made appliqués. Given that face vessels are considerably scarcer than other kinds of pottery, more than fifty finds from Moesia Superior make an enviable collection. In this and other provinces face vessels have been recovered from military camps, civilian settlements and necropolises, which suggests that they served more than one purpose. It is generally accepted that the faces-masks gave a protective role to the vessels, be it to protect the deceased or the family, their house and possessions. More than forty of all known finds from Moesia Superior come from Viminacium, a half of that number from necropolises. Although tangible evidence is lacking, there must have been several local workshops producing face vessels. The number and technological characteristics of the discovered vessels suggest that one of the workshops is likely to have been at Viminacium, an important pottery-making centre in the second and third centuries.

  11. The sentence superiority effect revisited.

    Snell, Joshua; Grainger, Jonathan

    2017-11-01

    A sentence superiority effect was investigated using post-cued word-in-sequence identification with the rapid parallel visual presentation (RPVP) of four horizontally aligned words. The four words were presented for 200ms followed by a post-mask and cue for partial report. They could form a grammatically correct sentence or were formed of the same words in a scrambled agrammatical sequence. Word identification was higher in the syntactically correct sequences, and crucially, this sentence superiority effect did not vary as a function of the target's position in the sequence. Cloze probability measures for words at the final, arguably most predictable position, revealed overall low values that did not interact with the effects of sentence context, suggesting that these effects were not driven by word predictability. The results point to a level of parallel processing across multiple words that enables rapid extraction of their syntactic categories. These generate a sentence-level representation that constrains the recognition process for individual words, thus facilitating parallel word processing when the sequence is grammatically sound.

  13. HISTOPATOLOGIA DA ADENOMIOSE EM VACAS ABATIDAS NO NORTE FLUMINENSE

    2006-10-01

    Full Text Available O presente experimento relata a ocorrência de adenomiose em vacas destinadas ao abate, na região do Norte Fluminense do Estado do Rio de Janeiro. O crescimento excessivo de glândulas e estroma endometriais por entre as fibras do miométrio é denominado adenomiose. A literatura cita que sua ocorrência não é muito comum nas fêmeas domésticas, contudo é observada em cadelas com hiperplasia endometrial cística. Muitos estudos sugerem que a adenomiose seja causada primariamente pela desorganização da membrana basal endométrio-miometral por estrógenos, progestágenos e prolactina, desencadeando uma invasão do miométrio pelos componentes endometriais. Atribui-se a esta enfermidade interferência na implantação do embrião, em função de alterações em nível vascular e estresse oxidativo, com conseqüente fibrose, subfertilidade e infertilidade. Amostras de 27 úteros de vacas, vazias, azebuadas, foram colhidas e protocoladas no Setor de Morfologia e Anatomia Patológica/LSA/CCTA/UENF, submetidas a histotécnica por inclusão em parafina e coloração pela hematoxilina e eosina e Van-Gieson. Idealizou-se um escore foi idealizado para lesões adenomióticas. Das 27 amostras, 18 (66,67% apresentaram adenomiose, contra 9 (33,33% sem o achado. Dez (55,56% apresentaram adenomiose superficial discreta; 2(11,12% profunda discreta; 1 (5,56% a do tipo moderada superficial; 3 (16,67% profunda moderada; e finalmente 2 (11,12% a do tipo acentuada profunda. É admissível que a exigüidade de descrições desta distrofia nas demais fêmeas domésticas não signifique uma negligência, e sim uma não-percepção da lesão, por se tratar de víscera de pouco valor comercial, de não ser demonstrada em biópsias endometriais e por estarem, em muitos casos, associadas a processos mais expressivos clinicamente, como hiperplasia endometrial cística, ovários policísticos, tumor de células da granulosa etc. Faz-se imprescindível o registro desta

    In this modern world, Solid Waste Management is very important in maintaining a high quality of life so humans must manage and store waste efficiently and safely. Almost every day each household generates garbage or wastes. People throw things improperly without knowing the consequences. The main objective of the study was to assess the residents' Solid Waste Management. Specifically, it aimed to answer the following questions: What is the profile of the respondents in terms of age, gender, educational attainment, occupation, monthly income, no. of household member; What is the knowledge of the respondents about Natural Environment?; How do respondents disposed garbage from the household?; What is the level of the respondents concern about proper waste management?; What is the willingness of the respondents to participate in proper Solid Waste Management?; What is the attitude of the respondents towards the Solid Waste Management? The said study was conducted at the Municipality of Linamon, which is a 5th class municipality located at the Eastern Gateway to Lanao del Norte, a south western Province of Northern Mindanao in the Philippines. The study was conducted in the 8 barangays of the Municipality of Linamon, namely: Bosque, Larapan, Mago-ong, Napo, Poblacion, Purakan, Robocon, and Samburon. The Municipality has 3 urban barangays and 4 rural barangays. The study revealed that most of the respondents interviewed were housewives. Out of 313 respondents, 67.10 % did not understand the term natural environment, with major issue currently affecting natural environment as "household garbage'. The respondents dispose the yard trimmings and papers through burning. The plastic and glass is disposed through the garbage truck. The metals and damaged home appliances were disposed by selling it to the junk shop. The respondents disposed their garbage into an open container specifically in a sack, collected by garbage trucks.

    Full Text Available Before initiating the building operations for the «Palos Verdes» School, the site was divided into two large horizontal surfaces, at different levels. The lower one served to accommodate the playing fields, a car park, the physical training building, and shop and ancillary buildings. On the higher of these two surfaces, and to the West of the access road, there is a car park and also the building and plot of ground devoted to agricultural technology, as well as the literary studies and general purpose buildings. As a complement to these, there is a series of blocks, arranged in parallel rows, which house the administrative offices, the art school, the craft's school, the general classrooms, and those devoted to higher education. The fascinating aspect of this school is the outstanding penetration of the architect's mind into the essential function of the project. Its most evident merit is the sense of comradeship and harmony that permeates the whole architectural manifold.Antes de construir el complejo escolar «Palos Verdes» se comenzó por crear, en el terreno, dos grandes mesetas a niveles diferentes. Sobre el inferior se organizaron: los campos de juegos, de deportes, un aparcamiento, el edificio para educación física y los destinados a tiendas y servicios. Sobre la meseta superior, al oeste de la vía de acceso, se dispuso un aparcamiento y el edificio y campo para adiestramiento agrícola; al este, otro aparcamiento, el edificio dedicado a materias literarias, y el destinado a usos múltiples. Completan las instalaciones de la escuela una serie de bloques paralelos: la administración, la escuela de arte, las clases de trabajos manuales, las aulas de enseñanzas generales, y las de los cursos superiores. Lo fascinante de este complejo escolar es la perfecta y magistral compenetración del arquitecto con el tema proyectado, y su mayor mérito, la sensación de cordialidad y armonía con el ambiente.

    Full Text Available No século XX diversos movimentos focalizaram a formação de professores em suas múltiplas possibilidades e o século XXI, como herança, precisa superar muitos desafios, dentre eles a formação dos docentes no/do Ensino Superior. A educação superior brasileira e portuguesa recebem professores formados, prioritariamente, para atuação em pesquisa, e submetem-se aos modelos alemão e norte-americano que alicerçam os cursos de pós-graduação stricto sensu, pautando-se na cisão entre ensino e pesquisa. O presente artigo trata dos processos formativos para a docência no Ensino Superior nos contextos brasileiro e português, a partir do olhar para duas pesquisas realizadas: a primeira retrata as ações desenvolvidas na implantação de um Programa de formação docente para professores ingressantes numa universidade pública brasileira e a segunda investigação traz dados de uma pesquisa desenvolvida em três universidades portuguesas sobre ações institucionais voltadas à docência no Ensino Superior. No primeiro caso, o estudo aponta que os professores consideram a formação continuada proveitosa, sugerindo continuidade, embora questionem a obrigatoriedade e algumas atividades realizadas à distância. No segundo, evidenciam-se a ausência de um Programa institucional e a capilaridade das ações formativas, trazendo algumas inovações; a não obrigatoriedade e seus desdobramentos e a carência de formação para a cultura digital.

    Full Text Available The Redwood highway, through the Californian forest, runs on a viaduct, as it crosses a mountain slope of about 45° inclination. The firm ground is fairly deep, and as an additional constructional difficulty, it was necessary to respect the natural beauty of the countryside. A structure of portal frames were built, forming a number of short spans. These spans were bridged with metal girders, on which a 19 m wide deck was placed. The columns are hollow and have a transversal cross beam, to join each pair. There was difficulty in excavating the foundations for the columns, as it was necessary to dig through the soft top soil, and also prevent this soil from hurting the trunks of the forest trees. Another significant difficulty in the construction of this viaduct was the access to the working site, since there were no suitable platforms from which to operate the appropriate machinery. This made it necessary to do a lot of the work by manual operation. As one of the edges of the deck is very close to the mountain side, a supporting beam was erected on this side. It was made of concrete, on metal piles. The formwork for the deck structure was placed on the concrete stems of the supporting piles.La autopista denominada Redwood (California salva, con un paso superior, la ladera de un bosque cuya pendiente es del 1/1.

    Pulmonary tuberculosis (PTB) and paragonimiasis remain as health problems in certain areas in the Philippines. Both share similar clinical manifestations, which include chronic productive cough, hemoptysis, dyspnea, fever, weight loss, and night sweats. This study aimed to determine the prevalence of PTB, paragonimiasis, and co-infections in Zamboanga del Norte, Philippines. This study was conducted in selected villages in two municipalities in Zamboanga del Norte. Patients with chronic cough were interviewed, examined, and requested to submit two sputum samples which were processed using Ziehl-Neelsen method to detect acid-fast bacilli (AFB), and NaOH concentration technique for the detection of Paragonimus ova. A total of 836 patients submitted sputum samples for examination. Prevalence was 6·7% (2·5-12·7%) for paragonimiasis and 1·9% (0·9-6·3%) for PTB. Co-infection rate was 0·3%, with two identified cases. Positivity rates for males and females were 9·6 and 5·8% for paragonimiasis and 3·4 and 1·2% for PTB. Pulmonary tuberculosis and paragonimiasis are co-endemic in Zamboanga del Norte, suggesting the need to integrate surveillance and control efforts. Strengthening local health systems through collaboration between different sectors is recommended for effective disease control. Development of more sensitive diagnostic tests is important for more accurate disease surveillance.

    Full Text Available The mesquite (Prosopis juliflora (Sw DC was established as a successful action of xerophilous introduction in Brazilian Northeast dry region. Its fruits are used in animal feed and the wood may be used as piles, firewood and charcoal. The species was introduced in 1942, spreading in "low areas" in Rio Grande do Norte, Paraiba, Pernambuco, Bahia and Piauí States. This article aims to elucidate how mesquite was introduced in Rio Grande do Norte State and to understand how it was spread. It was first introduced in Rio Grande do Norte State by the introduction experiments installed at São Miguel farm in the municipality of Angicos. The enthusiasm of technicians and researchers promoted the distribution of pods and seedlings on farms and cities in the state. In addition, there were government incentives to production, distribution and planting the species. This work aims to establish considerations to be used as historical basis on studies about this species and to consider aspects regarding current situation of this culture in Brazilian Northeast.

    Full Text Available Superior mesenteric artery syndrome is a rare and lifethreateningclinical condition caused by the compressionof the third portion of the duodenum between the aortaand the superior mesenteric artery’s proximal part. Thiscompression may lead to chronic intermittent, acute totalor partial obstruction. Sudden weight-loss and the relateddecrease in the fat tissue are considered to be the etiologicalreason of acute stenosis. Weight-loss accompaniedby nausea, vomiting, anorexia, epigastric pain, andbloating are the leading complaints.

  10. Superiorization: an optimization heuristic for medical physics.

    Herman, Gabor T; Garduno, Edgar; Davidi, Ran; Censor, Yair

    2012-09-01

    To describe and mathematically validate the superiorization methodology, which is a recently developed heuristic approach to optimization, and to discuss its applicability to medical physics problem formulations that specify the desired solution (of physically given or otherwise obtained constraints) by an optimization criterion. The superiorization methodology is presented as a heuristic solver for a large class of constrained optimization problems. The constraints come from the desire to produce a solution that is constraints-compatible, in the sense of meeting requirements provided by physically or otherwise obtained constraints. The underlying idea is that many iterative algorithms for finding such a solution are perturbation resilient in the sense that, even if certain kinds of changes are made at the end of each iterative step, the algorithm still produces a constraints-compatible solution. This property is exploited by using permitted changes to steer the algorithm to a solution that is not only constraints-compatible, but is also desirable according to a specified optimization criterion. The approach is very general, it is applicable to many iterative procedures and optimization criteria used in medical physics. The main practical contribution is a procedure for automatically producing from any given iterative algorithm its superiorized version, which will supply solutions that are superior according to a given optimization criterion. It is shown that if the original iterative algorithm satisfies certain mathematical conditions, then the output of its superiorized version is guaranteed to be as constraints-compatible as the output of the original algorithm, but it is superior to the latter according to the optimization criterion. This intuitive description is made precise in the paper and the stated claims are rigorously proved. Superiorization is illustrated on simulated computerized tomography data of a head cross section and, in spite of its generality

    To compare the efficacy and safety of Ahmed glaucoma valve (AGV) (New World Medical Inc., Rancho Cucamonga, CA) implantation in the superior versus inferior quadrants. Prospective parallel cohort study. A total of 106 eyes of 106 patients with refractory glaucoma. Consecutive patients with refractory glaucoma underwent AGV implantation in the superior or inferior quadrants. Main outcome measures included intraocular pressure (IOP) and rate of complications. Other outcome measures included best corrected visual acuity (BCVA), number of glaucoma medications, and success rate (defined as at least 30% IOP reduction and 5AGV implantation in the superior and inferior quadrants, respectively. Baseline characteristics were comparable in the study groups, except for preoperative IOP, which was higher in the superior group (P = 0.01). Patients were followed for a mean period of 10.6+/-8.49 months and 10.58+/-6.75 months in the superior and inferior groups, respectively (P = 0.477). BCVA was comparable between the groups at all postoperative visits (P>0.122). After 1 year, statistically significant but comparable IOP reduction from baseline (PAGV implants have similar intermediate efficacy in terms of IOP reduction, decrease in number of glaucoma medications, and preservation of vision. However, the inferior quadrants entail significantly more complications. It may be prudent to avoid AGV implantation in the inferior quadrants if the superior quadrants have no contraindications to surgery.

    Hockley, William E

    2008-10-01

    The picture superiority effect has been well documented in tests of item recognition and recall. The present study shows that the picture superiority effect extends to associative recognition. In three experiments, students studied lists consisting of random pairs of concrete words and pairs of line drawings; then they discriminated between intact (old) and rearranged (new) pairs of words and pictures at test. The discrimination advantage for pictures over words was seen in a greater hit rate for intact picture pairs, but there was no difference in the false alarm rates for the two types of stimuli. That is, there was no mirror effect. The same pattern of results was found when the test pairs consisted of the verbal labels of the pictures shown at study (Experiment 4), indicating that the hit rate advantage for picture pairs represents an encoding benefit. The results have implications for theories of the picture superiority effect and models of associative recognition.

MÉTODOS: Foram incluídos 358 indivíduos oriundos das consultas de especialidade que apresentavam resultados positivos para o antígeno da hepatite B durante pelo menos seis meses em dois hospitais do Norte de Portugal em 2008 e 2009. Os dados foram obtidos a partir dos processos clínicos, determinações laboratoriais feitas quando da genotipagem do vírus, ecografia e/ou ultra-sonografia e biópsia hepática. As características demográficas, marcadores víricos, carga viral e genótipos, e severidade da doença hepática foram avaliadas e comparadas entre sexos. RESULTADOS: Os genótipos A e D predominaram. A transmissão intrafamiliar ocorreu predominantemente nas mulheres. Um terço das mulheres apresentava ingestão alcoólica superior a 20 g/dia, aumentando para 58,9% nos homens. A ausência do AgHBe foi semelhante nos dois sexos (p = 0,662. Os parâmetros bioquímicos em geral apresentaram-se com valores mais altos nos homens, assim como nos estágios necro-inflamatório e de esteatose hepática (p = 0,003. CONCLUSÕES: As diferenças relativas às vias de transmissão da infecção pelo vírus da hepatite B entre homens e mulheres podem ser conseqüência de comportamentos de risco associadas ao género. A ingestão excessiva de álcool é predominante nos indivíduos do sexo masculino, assim como maior severidade da doença hepática em relação às mulheres.

    Full Text Available While Spain and other European and American countries celebrated the IV Centenario del Descubrimiento de América in 1892, the population at the northern part of México knew about the last apache incursion in Mexican territory and the rebelion of the neighbours of the Temochic little town. Both events will be used to analyze the situation of overarching violence in the North and surge of a feeling of freedom, independence and discontentedness among the authorities which would lead to the 1910 Revolution.

    Mientras España y otros países europeos y americanos celebraban el IV Centenario del Descubrimiento de América, en 1892, los habitantes del norte de México conocieron las noticias de la última incursión apache en territorio mexicano y la sublevación de los vecinos del pequeño poblado de Temochic. Ambos sucesos nos sirven para estudiar la situación de la violencia generalizada en el Norte y el nacimiento de un sentimiento de libertad, independencia y malestar entre las autoridades gubernativas que desembocaría en la revolución de 1910.

    Full Text Available La contaminación del aire en Paso del Norte es un asunto preocupante. Algunos ciudadanos y organismos no gubernamentales compelen a los gobiernos de México y Estados Unidos a buscar soluciones a este problema binacional. El Acuerdo de La Paz y las instituciones que nacieron junto con el Tratado de Libre Comercio representan esfuerzos para confrontar los problemas ambientales fronterizos; sin embargo, varios factores han impedido alcanzar resultados satisfactorios. La lección es que las instituciones han internalizado el problema a través de “programas de aire” y, por consiguiente, no han arribado a su solución. La modernización ecológica es una alternativa a la gestión ambiental tradicional. En este artículo expongo que en Paso del Norte ocurre un proceso de ecomodernización. Concluyo que aunque la modernización ecológica se presenta en la región, su éxito es limitado.

    2011-02-01

    Full Text Available Since historical times, mass movement processes have taken place in the Mexican territory as a result of its topography, heterogeneous lithology, intense rainfall and the impact of anthropic activity, particularly in mountainous areas such as the Sierra Norte de Puebla. In this region, as a result of extremely high rainfall, a large number of landslides occurred in October 1999. These were mainly slides and flows; they affected economic, structural and environmental aspects and caused the loss of dozens of human lives. Among the various approaches to analysis of this type of hazard, cartography is of considerable importance since it allows the understanding and assessment of spatial distribution, as well as of the interactions of elements of the terrain that determine slope instability. Hence, some studies of landslide hazard cartography have been carried out in Mexico; these have mainly been based on the overlaying, against a background of geographic information systems, of layers of information concerning the parameters that are involved in slope instability. However, there is a tendency for this approach to establish similar degrees of influence for all factors, regardless of specific local conditions. The present aim was to consider the influence of the five most important parameters controlling regional slope instability in the Sierra Norte de Puebla (slope, morphogenesis, relief dissection, deforestation and roads, and to validate the results by means of a recurrence index. Multicriteria analysis has allowed a map of susceptibility to mass movement processes to be produced for the municipality of Tlatlauquitepec.

    Full Text Available This study focuses on the analysis of high-resolution seismic profiles, integrated with sedimentological, echosounder, SRTM and satellite image datasets, of the Brazilian continental shelf adjacent to the Rio Grande do Norte State, NE Brazil. Located in the northeast of Brazil, the State of Rio Grande do Norte is bounded by two main coastal and shelf systems: the eastern coastal-shelf, from the Sagi River to the Touros High, and the northern coastal-shelf, extending from Touros High to Tibau. This shelf represents a modern, highly dynamic mixed carbonate-siliciclastic system characterized by reduced width and shallow depths as compared with other parts of the Brazilian shelf. It has an average width of 40 km, the shelf-break lying at a depth of ~ 60 m. This shelf is subject to the full strength of the westerly South Equatorial current combined with high winds and moderate to high tides and waves. A sharply defined stratigraphic boundary, probably between the Pleistocene and Holocene deposits, is clearly to be observed in the seismic record. Incised-valleys extending from the main river mouths (e.g.the Potengi, Açu, and Apodi to the shelf break dominate the area investigated and may indicate periods of lower sea level.Este estudo está direcionado ao conhecimento da plataforma continental brasileira adjacente ao Estado do Rio Grande do Norte, NE do Brasil, através da analise de perfis sismicos de alta resolução integrados a dados sedimentológicos, batimétricos, SRTM e imagens de satélites.

    Words are made of letters, and yet sometimes it is easier to identify a word than a single letter. This word superiority effect (WSE) has been observed when written stimuli are presented very briefly or degraded by visual noise. It is unclear, however, if this is due to a lower threshold...... for perception of words, or a higher speed of processing for words than letters. We have investigated the WSE using methods based on a Theory of Visual Attention. In an experiment using single stimuli (words or letters) presented centrally, we show that the classical WSE is specifically reflected in perceptual...... processing speed: words are simply processed faster than single letters. It is also clear from this experiment, that the word superiority effect can be observed at a large range of exposure durations, from the perceptual threshold to ceiling performance.

    Science.gov (United States)

    A priority for the Lake Superior CSMI was to identify susceptible nearshore eutrophication areas. We developed an integrated sampling design to collect baseline data for Lake Superior’s Chequamegon Bay to understand how nearshore physical processes and tributary loading relate to observed chlorophyll concentrations. Sampling included ship-based water samples combined with vertical CTD casts, continuous in situ towing and data collected from an autonomous underwater glider. Sampling was conducted during June, July and September. The glider collected regional data as part of three extended missions in Lake Superior over the same periods. During the study, two significant storm events impacted the western end of Lake Superior; the first occurred during July 11-12, with 8-10 inches of rain in 24hrs, and the second on July 21 with winds in excess of 161 km/h. Using GIS software, we organized these diverse temporal data sets along a continuous time line with temporally coincident Modis Satellite data to visualize surface sediment plumes in relation to water quality measurements. Preliminary results suggest that both events impacted regional water quality, and that nearshore physical forces (upwelling and currents) influenced the spatial variability. Results comparing in situ measures with remotely sensed images will be discussed. not applicable

    Stella Telles

    Full Text Available Este trabalho reflete o status dos traços laringais na língua Latundê, pertencente ao subgrupo Nambikwára do Norte, da família Nambikwára. Os dados foram coletados in loco pela autora entre os anos 1997-2001. Para a análise, considerou-se também a literatura disponível sobre outras línguas da família. O presente artigo está organizado em cinco seções: na primeira, são fornecidas informações sobre a família Nambikwára e os inventários segmentais de três línguas da família; na segunda, são apresentados os quadros fonológicos (consonantal e vocálico do Latundê; na terceira, encontram-se dados que evidenciam a realização dos traços laringais existentes em consoantes Latundê (glotalização e aspiração e o contraste do traço creaky voice, nas vogais; na quarta, são feitas considerações sobre a variação laringal no Latundê; finalmente, na quinta seção, são apresentadas reflexões sobre a correspondência entre segmentos com traço laringal do Latundê e do Mamaindê, outra língua Nambikwára do Norte. Os resultados do estudo evidenciaram que no Latundê as consoantes neutralizaram os traços laringais, enquanto que as vogais os mantêm contrastivamente. No interior do ramo do Norte, a correspondência entre consoantes Latundê e Mamaindê parece indicar que a primeira língua é mais inovadora no processo de mudança histórica.

    Full Text Available El eje fecundatorio norte-sur consiste en una relación ordinal entre una dimensión geográfica  (regiones de planificación Norte, Centro y Sur del Perú y el deseo de hijos de la mujer peruana, siendo el deseo mayor entre las norteñas y menor entre las sureñas. Análisis correlacionales, de covarianza, y de regresión fueron ejecutados en el banco de datos de la ENPA (N = 6,437 para determinar en las mujeres con hijos del norte, centro y sur (N = 1, 765 si variables tales como la altura/cultura (costa, sierra, urbanización, educación, ingreso, trabajo, conyugalidad, número de hijos vivos, y número de hijos muertos podrían dar cuenta del eje fecundatorio. El eje fecundatorio probó ser independiente de estas variables, aunque algunas interacciones aproximaron significación estadística. Se propuso una interpretación psicológica de  los resultados. La mujer norteña desearía más hijos debido a su mayor aceptación de un rol femenino dependiente y mayor disposición a satisfacer el machismo de su marido. La mujer sureña desearía menos hijos debido a su posición más autónoma en la vida familiar y mayores expectativas de participación activa en roles ocupacionales.

    Full Text Available A faunistic survey of the species of Callinectes Stimpson, 1871 carried out in the coastal and estuarine regions of the State of Rio Grande do Norte yielded five species: C. bocourti A. Milne Edwards, 1879; C. danae Smith, 1869; C. exasperatus (Gerstaecker, 1856; C. larvatus Ordway, 1863 and C. ornatus Ordway, 1863. Specimens examined consist of those collected on a monthly basis from three fixed stations within the estuary of Potengi, Natal during a period of two years and those obtained from other localities. Among the species occuring in the region, C. danae is more abundant and has a wider range of tolerance of salinity while C. larvatus is restricted to the marine habitat. Though C. danae sustains important artisan fishery, C. bocourti of large size also contribute to the fishery.

    Full Text Available El poblamiento arcaico del Área Centro Sur Andina, iniciado en los albores del XI milenio AP., es producido por cazadores y recolectores que ocupan progresivamente el área altiplánica, los valles fluviales y las cuencas intermedias derivados de grupos paleoindios. El proceso de dispersión que involucra la exploración, conquista y adaptación a distintos ambientes, biotopos y ecosistemas produjo la fragmentación de la población original de los cazadores holocénicos tempranos (11000-8000 AP y su progresiva divergencia genética posiblemente asociada con diferentes modelos adaptativos propuestos por la arqueología (Núñez y Santoro, 1990. Si bien los registros bioantropológicos de épocas tan tempranas son sumamente escasos, la estructura de la población antigua se proyecta en el tiempo permitiendo explicar la variación geográfica de los grupos arcaicos tardíos y formativos. En el presente informe se analizan los resultados de varios trabajos realizados con materiales bien cronometrados para explicar el poblamiento de la costa norte de Chile. Se emplearon datos métricos y no métricos obtenidos en relevamientos modernos de sitios de la costa de Arica y Valle de Azapa, Pisagua, Norte Semiárido y Zona Central de Chile.

    Full Text Available Esta investigación se llevó a cabo para determinar la distribución espacial de la densidad (captura por unidad de área - CPUA y de la estructura de tallas de Eucinostomus argenteus y su relación con las variables ambientales en la zona norte del Caribe colombiano. Los datos se tomaron durante un crucero de investigación realizado en la época seca (febrero de 2006 entre Puerto Estrella (La Guajira y Santa Marta (Magdalena. Las muestras biológicas se recolectaron con una red de arrastre (en estratos de profundidad < 50 m y 50-100 m siguiendo un diseño de muestreo sistemático. Los individuos ma- duros y de tallas mayores se encontraron distribuidos principalmente entre Manaure y Punta Gallinas (La Guajira, donde la plataforma continental es muy ancha y la oceano- grafía local está modulada por la surgencia estacional. Los peces juveniles, se distribu- yeron al sur del área de estudio, entre Boca Camarones (La Guajira y el río Buritaca (Magdalena, cerca de la costa. En este sector la plataforma es muy estrecha y con alta productividad biológica por la presencia de ríos, manglares y pastos marinos, sirviendo como zona de alimentación y refugio para E. argenteus. En general, los resultados sugieren que las variables ambientales son importantes para la distribución espacial de la abundancia y las tallas de E. argenteus en la zona norte del Caribe colombiano, siendo la temperatura y la profundidad las variables que predijeron mejor la distribución espacial de la especie.

  6. Surgical management of superior sulcus tumors.

    Dartevelle, P; Macchiarini, P

    1999-01-01

    Superior sulcus tumor refers to any primary lung cancer presenting with constant pain in the nerve distribution of the eighth cervical, first and second thoracic nerve roots and Horner's syndrome caused by invasion of the stellate ganglion. The pain is steady, severe, and unrelenting, involving the shoulder, the vertebral margin of the scapula and ulnar distribution of the arm to the elbow and finally to the ulnar surface of the forearm, and the small and ring fingers of the hand (Pancoast-Tobias syndrome). Weakness and atrophy of the hand muscles can also occur as the lesions spreads to involve the first and second ribs and vertebrae. Radiologically, there is a small shadow at the extreme apex of the lung with rib and possible vertebral body invasion. Pulmonary symptoms are less frequent because of the peripheral location of the lesions. Since Shaw and Paulson approached superior sulcus tumors in 1961 by using preoperative radiation-therapy (30 to 45 Gy in four weeks including the primary tumor, mediastinum and supraclavicular region) followed by surgical resection, this radiosurgical approach shortly became the standard treatment yielding better disease control and survival than that offered by other treatment modalities. It has now become evident that en bloc resection of the chest wall, involved adjacent structures as well as lobectomy must be considered the standard surgical approach for superior sulcus tumors combined with external radiation (preoperative, postoperative, or both). The goal of the operation is the complete and en bloc resection of the upper lobe in continuity with the invaded ribs, transverse processes, subclavian vessels, T1 nerve root, upper dorsal sympathetic chain and prevertebral muscles.

    O objetivo deste trabalho é fornecer informações sobre a composição centesimal e o valor calórico dos peixes Clupeiformes Chirocentrodon bleekerianus, Pellona harroweri e Lycengraulis grossidens. Os espécimes foram coletados entre 2007 e 2010 na costa norte do estado do Rio de Janeiro. Análises bromatológicas (proteína, lipídio e matéria mineral foram realizadas em amostras compostas, e o teor de carboidrato e a energia bruta foram calculados a partir de relações entre as variáveis. As espécies de peixes foram significativamente distintas em relação ao porte (comprimento total e peso, composição centesimal e energia bruta, e apenas o teor de carboidrato foi similar. A espécie L. grossidens foi representada por indivíduos maiores e com teor de lipídio superior, enquanto C. bleekerianus e P. harroweri apresentaram os maiores percentuais de proteína e matéria mineral, além de valores de energia bruta mais elevados. O percentual de proteína foi diretamente proporcional ao valor de energia bruta, enquanto o percentual de lipídio apresentou relação inversa com essas duas variáveis. O presente estudo servirá de base para o entendimento de a seletividade alimentar de carnívoros marinhos em regiões costeiras e para a elaboração de modelos de bioenergética.

    2013-08-01

    Full Text Available A geração de energia elétrica no Brasil é predominantemente renovável, com a geração interna hidráulica sendo superior a 74% do total de sua matriz energética. O racionamento de energia elétrica ocorrido em 2001, devido à falta de chuvas, levou o país a incrementar a participação de fontes alternativas de energia. Esta necessidade por novas fontes de energia faz com que as potencialidades regionais sejam aproveitadas, o que configura a mudança do modelo de geração, passando de geração centralizada para geração distribuída. Dentre as fontes alternativas de energia, a solar apresenta-se como uma fonte bastante promissora para o Brasil, tendo em vista que a maior parte do seu território está localizada próximo à linha do equador, o que acarreta em um dia de maior duração solar. O Rio Grande do Norte (RN tem um dos maiores índices de incidência solar do território brasileiro, o que o torna apto a receber investimentos para a instalação de usinas solares fotovoltaicas. Este artigo analisará o potencial de geração da energia solar fotovoltaica no RN através de medições solarimétricas realizadas em Natal, capital do estado.

La biomasa aérea promedio fue de 243.44±9.82tn/ha con un incremento anual promedio de 2.9ton/ha, valor superior a los reportados, lo cual sugiere que el equilibrio para este bosque no se ha alcanzado. De acuerdo con las observaciones de campo, este bosque parece estar recuperándose de una alteración pasada.

    Inspired by the structure of cancellous bone and the nutrition metabolism of articular cartilage, we present a novel concept for a synthetic articular-cartilage-like material. The bioinspired material possesses a low coefficient of friction even under ultrahigh loads and has an extremely long lifetime. Furthermore, the composite shows zero-wear behavior and causes negligible wear damage to the friction pair. The superior tribological performance is attributed to the spontaneously generated articular-cartilage-like layer, which is constantly replenished by frictional heat and pressure. Our findings open a new area for industrial scale engineering applications to improve the friction and wear properties of moving components.

    Full Text Available Superior vena cava (SVC syndrome is most commonly the insidious result of decreased vascular flow through the SVC due to malignancy, spontaneous thrombus, infections, and iatrogenic etiologies. Clinical suspicion usually leads to computed tomography to confirm the diagnosis. However, when a patient in respiratory distress requires emergent airway management, travel outside the emergency department is not ideal. With the growing implementation of point-of-care ultrasound (POCUS, clinicians may make critical diagnoses rapidly and safely. We present a case of SVC syndrome due to extensive thrombosis of the deep venous system cephalad to the SVC diagnosed by POCUS. [West J Emerg Med. 2014;15(6:715-718

    The patient was a 25-year-old male college student with a chief complaint of right shoulder pain. The patient was initially diagnosed with bicipital tendinitis by his physician and had been treated for 4 weeks by a physical therapist. However, his symptoms did not improve and he was unable to return to his preinjury activity levels, so he sought the services of another physical therapist for a second opinion. Due to concern for a labrum tear, the physical therapist referred the patient to an orthopaedic surgeon. Magnetic resonance arthrography revealed findings consistent with a superior labrum anterior-to-posterior tear.

    Full Text Available A veia cava superior é formada pela união das duas veias inominadas, direita e esquerda, e localiza-se no mediastino médio, à direita da artéria aorta e anteriormente à traquéia. A síndrome da veia cava superior representa um conjunto de sinais (dilatação das veias do pescoço, pletora facial, edema de membros superiores, cianose e sintomas (cefaléia, dispnéia, tosse, edema de membro superior, ortopnéia e disfagia decorrentes da obstrução do fluxo sanguíneo através da veia cava superior em direção ao átrio direito. A obstrução pode ser causada por compressão extrínseca, invasão tumoral, trombose ou por dificuldade do retorno venoso ao coração secundária a doenças intra-atriais ou intraluminais. Aproximadamente 73% a 97% dos casos de síndrome da veia cava superior ocorrem durante a evolução de processos malignos intratorácicos. A maioria dos pacientes com a síndrome secundária a neoplasias malignas é tratada sem necessidade de cirurgia, através de radioterapia ou quimioterapia, ou através da colocação de stents endoluminais. Quando a síndrome é de etiologia benigna, o tratamento é feito através de medidas clínicas (anticoagulação, elevação da cabeça, etc. ou, em casos refratários, através de angioplastia, colocação de stents endoluminais e cirurgia.The superior vena cava is formed by the union of the right and left brachiocephalic veins. It is located in the middle mediastinum, to the right of the aorta and anterior to the trachea. Superior vena cava syndrome consists of a group of signs (dilation of the veins in the neck, facial swelling, edema of the upper limbs, and cyanosis and symptoms (headache, dyspnea, cough, orthopnea and dysphagia caused by the obstruction of blood flow through the superior vena cava to the right atrium.

    A 59-year-old man with a 4-week history of dyspnea, coughing, and chest discomfort was referred to hospital for further evaluation. Moreover, he reported fever and fatigue. There were neither cardiovascular risk factors nor drug medication. 6 months earlier, a deep vein thrombosis of his left lower limb was diagnosed followed by an anticoagulation for 4 weeks. Physical examination revealed a dilatation of the neck veins with a present Kussmaul sign and a diastolic murmur at the left lower sternal border. The findings on the rest of his physical examination were unremarkable. Electrocardiography showed normal sinus rhythm, low voltage, and anterolateral T wave inversion. Initial laboratory results were remarkable for elevated lactate dehydrogenase level. Transthoracic echocardiography revealed a small pericardial effusion with a large intracardiac mass adjacent to the right atrium. Thoracic computed tomography confirmed the tumor mass and showed enlargement of mediastinal lymph nodes. The patient underwent transesophageal echocardiography-guided transvenous biopsy of the tumor. The immunohistology of the specimen revealed non-Hodgkin's lymphoma. The patient subsequently received a chemotherapy with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisolone. His clinical response after the first cycle was remarkable with total regression of the superior vena cava syndrome. After the third cycle of therapy, both tumor and pericardial effusion had disappeared. A cardiac tumor is a rare cause of a superior vena cava syndrome. Tissue biopsy is warranted to guide diagnosis and therapy. Transvenous biopsy is generally safe when guided by echocardiography.

    Superior canal dehiscence syndrome (SCDS) is an increasingly recognized cause of hearing loss and vestibular symptoms, but the etiology of this condition remains unknown. To describe 7 cases of SCDS across 3 families. This retrospective case series included 7 patients from 3 different families treated at a neurotology clinic at a tertiary academic medical center from 2010 to 2014. Patients were referred by other otolaryngologists or were self-referred. Each patient demonstrated unilateral or bilateral SCDS or near dehiscence. Clinical evaluation involved body mass index calculation, audiometry, cervical vestibular evoked myogenic potential testing, electrocochleography, and multiplanar computed tomographic (CT) scan of the temporal bones. Zygosity testing was performed on twin siblings. The diagnosis of SCDS was made if bone was absent over the superior semicircular canal on 2 consecutive CT images, in addition to 1 physiologic sign consistent with labyrinthine dehiscence. Near dehiscence was defined as absent bone on only 1 CT image but with symptoms and at least 1 physiologic sign of labyrinthine dehiscence. A total of 7 patients (5 female and 2 male; age range, 8-49 years) from 3 families underwent evaluation. Family A consisted of 3 adult first-degree relatives, of whom 2 were diagnosed with SCDS and 1 with near dehiscence. Family B included a mother and her child, both of whom were diagnosed with unilateral SCDS. Family C consisted of adult monozygotic twins, each of whom was diagnosed with unilateral SCDS. For all cases, dehiscence was located at the arcuate eminence. Obesity alone did not explain the occurrence of SCDS because 5 of the 7 cases had a body mass index (calculated as weight in kilograms divided by height in meters squared) less than 30.0. Superior canal dehiscence syndrome is a rare, often unrecognized condition. This report of 3 multiplex families with SCDS provides evidence in support of a potential genetic contribution to the etiology

    Accusations of entrenched political partisanship have been launched against both conservatives and liberals. But is feeling superior about one's beliefs a partisan issue? Two competing hypotheses exist: the rigidity-of-the-right hypothesis (i.e., conservatives are dogmatic) and the ideological-extremism hypothesis (i.e., extreme views on both sides predict dogmatism). We measured 527 Americans' attitudes about nine contentious political issues, the degree to which they thought their beliefs were superior to other people's, and their level of dogmatism. Dogmatism was higher for people endorsing conservative views than for people endorsing liberal views, which replicates the rigidity-of-the-right hypothesis. However, curvilinear effects of ideological attitude on belief superiority (i.e., belief that one's position is more correct than another's) supported the ideological-extremism hypothesis. Furthermore, responses reflecting the greatest belief superiority were obtained on conservative attitudes for three issues and liberal attitudes for another three issues. These findings capture nuances in the relationship between political beliefs and attitude entrenchment that have not been revealed previously.

    On 4 July 1999, a severe convective windstorm, known as a derecho, caused extensive damage to forested regions along the United States/Canada border, west of Lake Superior. There were 665,000 acres of forest destroyed in the Boundary Waters Canoe Area Wilderness (BWCAW) in Minnesota and Quetico Provincial Park in Canada, with approximately 12.5 million trees blown down. This storm resulted in additional severe weather before and after the occurrence of the derecho, with continuous cloud-to-ground (CG) lightning occurring for more than 34 hours during its path across North America. At the time of the derecho the percentage of positive cloud-to-ground (+CG) lightning measured by the Canadian Lightning Detection Network (CLDN) was greater than 70% for more than three hours, with peak values reaching 97% positive CG lightning. Such high ratios of +CG are rare, and may be useful indicators of severe weather.

    With its long duration and high gain antenna (HGA) feed thermal constraint; the NASA Solar-TErestrial RElations Observatory (STEREO) solar conjunction mission phase is quite unique to deep space operations. Originally designed for a two year heliocentric orbit mission to primarily study coronal mass ejection propagation, after 8 years of continuous science data collection, the twin STEREO observatories entered the solar conjunction mission phase, for which they were not designed. Nine months before entering conjunction, an unforeseen thermal constraint threatened to stop daily communications and science data collection for 15months. With a 3.5 month long communication blackout from the superior solar conjunction, without ground commands, each observatory will reset every 3 days, resulting in 35 system resets at an Earth range of 2 AU. As the observatories will be conjoined for the first time in 8 years, a unique opportunity for calibrating the same instruments on identical spacecraft will occur. As each observatory has lost redundancy, and with only a limited fidelity hardware simulator, how can the new observatory configuration be adequately and safely tested on each spacecraft? Without ground commands, how would a 3-axis stabilized spacecraft safely manage the ever accumulating system momentum without using propellant for thrusters? Could science data still be collected for the duration of the solar conjunction mission phase? Would the observatories survive? In its second extended mission, operational resources were limited at best. This paper discusses the solutions to the STEREO superior solar conjunction operational challenges, science data impact, testing, mission operations, results, and lessons learned while implementing.

    Full Text Available As canine rabies control in Africa and Asia transitions from research-led proof-of-concept studies to government-led programs for elimination, experience and evidence of their impact and costs must be shared for the benefit of future programs. The Ilocos Norte Communities against Rabies Exposure project was implemented in April 2012 by the provincial veterinary and health offices and supported by many other partners. It delivered a comprehensive dog vaccination program and increased awareness of the need for postexposure prophylaxis (PEP, aiming to eliminate human and animal rabies cases from Ilocos Norte by 2015. Prior to the intervention, confirmed rabies cases in dogs were between 19 and 50 per year (2008–2011. The primary outcome of the project was a reduction in rabies cases in both dogs and humans to 0 in 2014 and 2015, which has subsequently been maintained. Animal bite consultations increased significantly during the project. Economic data for the dog vaccination and PEP components of the project were collated for two sites: Laoag City (an urban setting and Dingras Municipality (a rural setting between 2012 and 2014. The average programmatic cost of vaccinating each dog was $4.54 in Laoag City and $8.65 in Dingras, and costs fell as the project reached more dogs. The average costs of providing PEP were $69.72 per patient and $49.02 per patient for the two sites, respectively, again falling as the project reached more people. External donor contributions contributed less than 20% of dog vaccination costs and less than 1% of PEP costs. The project demonstrated that rabies elimination can be achieved in a short period of time, with concerted effort across multiple sectors. A lack of clear dog population estimates hampered interpretation of some aspects of the programme. From 2016, the provincial government has assumed complete responsibility for the programme and must now continue the vaccination and surveillance efforts. Although

    Full Text Available Fundamento: La anisakiasis es una zoonosis parasitaria producida por larvas vivas de nematodos de la Familia Anisakidae, que se localizan en la cavidad corporal y el sistema muscular de peces teleósteos y moluscos cefalópodos. El hombre las ingiere accidentalmente al consumir pescado infestado crudo o poco cocinado. El cuadro clínico está caracterizado por síndrome gástrico-intestinal. El objetivo del presente trabajo es conocer la frecuencia de parasitación por larvas de anisákidos en pescados frescos comercializados en el norte de la provincia de Córdoba. Métodos: Durante un período de 9 meses se tomaron muestras de las especies más comercializadas de pescados marinos en todas los establecimientos del sector. El análisis parasitológico se realizó en el Laboratorio de Salud Pública de Peñarroya mediante el método de la disección. Se analizaron un total de 1.261 muestras de 18 especies distintas. Resultados: La frecuencia total de parasitación fue del 15,8%. La especie más parasitada fue la bacaladilla (Micromesistius poutassou, con un porcentaje de parasitación del 42%, y se detectaron también larvas de Anisakidos en: pijota (Merlucius merlucius un 27,5%, pescadilla (Merlucius sp. un 26%, Caballa (Scomber scombrus un 20,6%, brótola (Phycis blennoides un 6,2%, boquerón (Engraulis encrasicolus un 5,6% y faneca (Trisopterus luscus un 5,5% de muestras parasitadas. La distribución mensual de los resultados refleja un aumento de la parasitación en los meses de primavera, descendiendo progresivamente hasta los últimos meses del año. Conclusiones: Existe una incidencia significativa de infestación por anisakidos en las especies de pescados comercializadas en el norte de Córdoba. No obstante, la dificultad para detectar el parásito, la valoración imprecisa del grado de parasitación tolerable o inaceptable que señala el marco normativo, la circunstancia de que algunos platos tradicionales elaborados con pescado crudo

El análisis de los datos polínicos de yacimientos y turberas, así como de la fauna, permiten reconstruir las características medioambientales durante el Tardiglaciar y la transición al Postglaciar, y precisar las fases de ocupación de la Meseta. La calibración de las dataciones 14C de los yacimientos de la Meseta Norte y de otros cercanos en el valle medio del Ebro y Navarra, permiten relacionar las ocupaciones con el nuevo marco crono-climático establecido a partir de los sondeos en el hielo de Groenlandia. Según estos datos, la horquilla temporal establecida es más reducida de lo que se supone habitualmente, discutiéndose la cronología tradicionalmente propuesta para los yacimientos y el Arte parietal de la Meseta Norte española.

    Full Text Available en la Sierra Norte de Oaxaca se ubican municipios que han desarrollado estrategias organizativas y producti - vas, donde los actores sociales y sus instancias de gobier - no comunal se han posicionado como agentes clave. Estas experiencias se llevan a cabo en territorios que, además de contar con recursos forestales, han “redescubierto” nue - vas formas de aprovechamiento de sus recursos hídricos y paisajísticos, entre otros. Se trata de espacios habitados principalmente por poblaciones de ascendencia indígena, que tienen regímenes comunales de tenencia de la tierra, y que mediante empresas comunitarias usan y usufructúan sus principales recursos naturales. En este trabajo se explo - ra el contexto en que surgió esta modalidad productiva, y se propone identificar y explicar los factores que intervie - nen en su funcionamiento. Sobre todo interesa destacar tres ejes: los espacios de gobernanza y gestión social de re - cursos; el trabajo cooperativo y las estrategias de reciproci -dad y la construcción de una racionalidad socioecológica, que prefigura determinadas estrategias de conservación en regiones de alto valor ambiental.

    Full Text Available En el presente trabajo se analiza el mercado laboral en Sonora y los demás estados de la frontera norte de México, a partir de la evolución de la industria maquiladora y su relación con el empleo y los salarios regionales. Para una economía de bienes comercializables y no comercializables, que utiliza un modelo en el que el comercio internacional influye sobre el empleo y los salarios de la región, y con base en una estimación con datos de panel, se estudia el efecto de la demanda del empleo y los salarios provenientes de la demanda de exportaciones de bienes manufacturados sobre el sector no maquilador, de 1997 a 2004, con énfasis en la etapa de cierre de empresas maquiladoras en 2001 y 2003. Los resultados sugieren que, para este periodo en particular, el empleo en los sectores distintos a la maquila determina el equilibrio en el mercado de trabajo, y que los salarios de las maquiladoras son influidos por el equilibrio en la oferta y demanda de dichos sectores.

    Full Text Available Temperature raise and changes in precipitation expected under climate change scenarios will impact on species distribution at regional al global level; although in Mexico few studies of plant species vulnerability exist. The objectives of this study were: a to determine plant functional types of plants based on life forms; b to determine biogeography distribution and actual climate and altitude gradients and, c to define vulnerability of plant functional types under climate change scenarios in Sierra Norte of Oaxaca (SNO. Potential response of functional groups was based on an ensemble of eight general circulation models with four emissions scenarios at global scale and, a Japanese model of very high regional resolution (20 x 20 km. To characterize groups of climate response, dominant species were defined for seven vegetation types in SNO. Climate change scenarios ensemble suggested an increment of temperature between 1.5 and 2.5º C, and a change in precipitation between +5 and –10 %. Sensitivity analysis suggested that for climate change scenarios in 2050 genera like Abies and Pinus would diminish their geographic distribution. Results of this study can help to define conservation strategies and manage of those species less tolerant to perturbation in actual and future climate at regional scales.

    Surface ozone pollution has been a persistent environmental problem in the US and Europe as well as the developing countries. A key prerequisite to find effective alternatives to meeting an ozone air quality standard is to understand the importance of local anthropogenic emissions, the significance of biogenic emissions, and the contribution of long-range transport. In this study, an air quality modeling system that includes chemistry and transport, CMAQ, an emission processing model, SMOKE, and a mesoscale numerical meteorological model, WRF, has been applied to investigate an ozone event occurring during the period of the 1996 Paso del Norte Ozone Campaign. The results show that the modeling system exhibits the capability to simulate this high ozone occurrence by providing a comparable temporal variation of surface ozone concentration at one station and to capture the spatial evolution of the event. Several sensitivity tests were also conducted to identify the contributions to high surface ozone concentration from eight VOC subspecies, biogenic VOCs, anthropogenic VOCs and long-range transportation of ozone and its precursors. It is found that the reductions of ETH, ISOP, PAR, OLE and FORM help to mitigate the surface ozone concentration, and like anthropogenic VOCs, biogenic VOC plays a nonnegligible role in ozone formation. But for this case, long-range transport of ozone and its precursors appears to produce an insignificant contribution.

    Full Text Available The stomach contents of 18 Guiana dolphins stranded or accidentally caught by fishing around Norte Bay of Santa Catarina Island between 1990 and 2006 were examined. The small population of Guiana dolphins studied showed a varied diet, and prey was caught disproportionately. The stomach contents of these dolphins consisted of 448 prey remains coming from 18 species and 10 families. Their diet primarily consisted of fish, but also shrimp and squid. The most important species were cutlass fish (Trichiurus lepturus and white mouth croaker (Micropogonias furnieri, which together comprised 75% of the total biomass. Although prey size ranged widely from 1.4 to 92.8 cm, a prevalence of prey smaller than 20 cm was observed. There was a predominance of prey living in moderate or large schools. The prey also had a wide vertical distribution in the water column. Our results support the opportunistic feeding habit of the Guiana dolphin, since its diverse diet was clearly guided by the availability and accessibility of resources in its habitat.

    Full Text Available Wind power generation has a reputation for being environmentally friendly. However, beyond its clean and renewable aspects, the exploration fields can also be assessed in its relationship with the geographical space, as the risks involved in this activity can be identified in all project phases, going from its implementation to the final moment where the actual energy generation takes place. This article provides a description of the risks related to the physical environment of the wind power generation fields of Macambira I and II, Baixa do Feijão and Aventura, all located in the state of Rio Grande do Norte, Brazil. Although the research focuses on the physical context of the generation fields, it also indicates that social relationships are affected by it. Particularly, the geology mapping demonstrates that there are risks related to the presence of caves. This morphology can be seen on the Jandaíra Formation limestone, which is marked by a subterranean tunnel network that occurs in plain terrains. Beyond the geotechnical aspect, which exposes the wind power towers to some risk, there are environmental concerns regarding the regional hidrogeology and the speleological patrimony, as well as the fossil layers that are present on the sedimentary formations. Furthermore, the regional seismic context can also offer risks to the installation of wind power generation towers.

    Full Text Available This study aimed to provide valuable information about the realities of the Queen pineapple (QP farmers in Camarines Norte, highlighting their farming practices and worldview about sustainable development. Most of the respondents are owner-operator having a mean farm size of 1.33 hectares devoted to queen pineapple farming and crop diversification with two to seven crops combined to augment income. Cropping pattern employed by most of the respondents is multiple cropping, specifically intercropping, rotational cropping, and fallowing. Soil nutrient and weed management of most respondents is conventional: inorganic fertilizers and chemical based, respectively. However, pest control management by most of the respondents is of the alternative method. Overall, QP farmer respondents were found to be practicing alternative farming methods. The problems cited by the respondents were mainly production, marketing and communication-related. The respondents showed that they have moved towards alternative farming. However, more attention should be given to soil nutrient and weed management practices. Strengthening communication-related activities, improved technology, and ensured availability of resources is necessary to have good avenue for change. These findings should make agencies concerned to promote alternative farming and sustainable agriculture. The significant attributes of the QP farmer respondents can be used as entry point for any development program to fully advocate alternative farming among the local people as a social movement.

    Full Text Available En el período que cubre los siglos xvi y xvii, los valles montañeses del norte de Navarra atestiguaron una agudizada conflictividad social entre los linajes o «parientes mayores» y las comunidades de vecinos de cada localidad o valle por la cual éstas discutieron los privilegios de los primeros en un intento —conseguido casi siempre— de cercenar cualquier proceso tendente a la señorialización. Los rasgos tipológicos de esa conflictividad muestran la presencia de una triplicidad de variantes según el ámbito concreto de lo dirimido en cada pleito: conflictos por preferencias en las iglesias, conflictos por diezmos y construcción de molinos y conflictos por alcaldías perpetuas y concesiones jurisdiccionales. No obstante, la circunstancia de que en la mayoría de los casos que se describen a continuación consten dos o tres de esas variantes prueba el carácter para nada anecdótico de esas diferencias.

    Full Text Available Las prácticas curativas de los grupos yumanoparlantes del norte de Baja California estuvieron bajo el liderazgo del kusiyai, una figura desvanecida en los modernos estudios etnográficos, pero cuyas actividades pueden ser reconstruidas a partir de los reportes de etnógrafos, geógrafos y exploradores de principios del siglo veinte. Es posible observar en esas actividades ciertos patrones similares a los que siguen las prácticas curativas del chamanismo. Más aún, esas actividades pueden ser reconstruidas en más detalle si utilizamos el paradigma chamánico para organizar los diversos tipos de material relacionado. Cabe señalar, por otra parte, que esta perspectiva ofrece en lo particular la expectativa de un posible resurgimiento futuro de esta tradición cultural. La perspectiva moderna sobre los universales del chamanismo y sobre los aspectos innatos de las actividades chamánicas es congruente con las creencias tradicionales de que los chamanes eran autodidactas en el desarrollo de sus relaciones con los poderes y lugares espirituales.

  20. Lake Superior Coastal Wetland Fish Assemblages and ...

    Science.gov (United States)

    The role of the coastal margin and the watershed context in defining the ecology of even very large lakes is increasingly being recognized and examined. Coastal wetlands are both important contributors to the biodiversity and productivity of large lakes and important mediators of the lake-basin connection. We explored wetland-watershed connections and their relationship to wetland function and condition using data collected from 37 Lake Superior wetlands spanning a substantial geographic and geomorphic gradient. While none of these wetlands are particularly disturbed, there were nevertheless clear relationships between watershed landuse and wetland habitat and biota, and these varied consistently across wetland type categories that reflected the strength of connection to the watershed. For example, water clarity and vegetation structure complexity declined with decreasing percent natural land cover, and these effects were strongest in riverine wetlands (having generally large watersheds and tributary-dominated hydrology) and weakest in lagoon wetlands (having generally small watersheds and lake-dominate hydrology). Fish abundance and species richness both increased with decreasing percent natural land cover while species diversity decreased, and again the effect was strongest in riverine wetlands. Lagoonal wetlands, which lack any substantial tributary, consistently harbored the fewest species of fish and a composition different from the more watershed-lin

    Deficits in language are a core feature of autism. The superior temporal gyrus (STG) is involved in auditory processing, including language, but also has been implicated as a critical structure in social cognition. It was hypothesized that subjects with autism would display different size-function relationships between the STG and intellectual-language-based abilities when compared to controls. Intellectual ability was assessed by either the Wechsler Intelligence Scale for Children-Third Edition (WISC-III) or Wechsler Adult Intelligence Scale-Third Edition (WAIS-III), where three intellectual quotients (IQ) were computed: verbal (VIQ), performance (PIQ), and full-scale (FSIQ). Language ability was assessed by the Clinical Evaluation of Language Fundamentals-Third Edition (CELF-3), also divided into three index scores: receptive, expressive, and total. Seven to 19-year-old rigorously diagnosed subjects with autism (n = 30) were compared to controls (n = 39; 13 of whom had a deficit in reading) of similar age who were matched on education, PIQ, and head circumference. STG volumes were computed based on 1.5 Tesla magnetic resonance imaging (MRI). IQ and CELF-3 performance were highly interrelated regardless of whether subjects had autism or were controls. Both IQ and CELF-3 ability were positively correlated with STG in controls, but a different pattern was observed in subjects with autism. In controls, left STG gray matter was significantly (r = .42, p receptive language on the CELF-3; in contrast, a zero order correlation was found with autism. When plotted by age, potential differences in growth trajectories related to language development associated with STG were observed between controls and those subjects with autism. Taken together, these findings suggest a possible failure in left hemisphere lateralization of language function involving the STG in autism.

  4. Physiological models of the lateral superior olive

    In computational biology, modeling is a fundamental tool for formulating, analyzing and predicting complex phenomena. Most neuron models, however, are designed to reproduce certain small sets of empirical data. Hence their outcome is usually not compatible or comparable with other models or datasets, making it unclear how widely applicable such models are. In this study, we investigate these aspects of modeling, namely credibility and generalizability, with a specific focus on auditory neurons involved in the localization of sound sources. The primary cues for binaural sound localization are comprised of interaural time and level differences (ITD/ILD), which are the timing and intensity differences of the sound waves arriving at the two ears. The lateral superior olive (LSO) in the auditory brainstem is one of the locations where such acoustic information is first computed. An LSO neuron receives temporally structured excitatory and inhibitory synaptic inputs that are driven by ipsi- and contralateral sound stimuli, respectively, and changes its spike rate according to binaural acoustic differences. Here we examine seven contemporary models of LSO neurons with different levels of biophysical complexity, from predominantly functional ones (‘shot-noise’ models) to those with more detailed physiological components (variations of integrate-and-fire and Hodgkin-Huxley-type). These models, calibrated to reproduce known monaural and binaural characteristics of LSO, generate largely similar results to each other in simulating ITD and ILD coding. Our comparisons of physiological detail, computational efficiency, predictive performances, and further expandability of the models demonstrate (1) that the simplistic, functional LSO models are suitable for applications where low computational costs and mathematical transparency are needed, (2) that more complex models with detailed membrane potential dynamics are necessary for simulation studies where sub-neuronal nonlinear

    2015-08-04

    Industrial facilities participating in the U.S. Department of Energy’s (US DOE) Superior Energy Performance (SEP) program are finding that it provides them with significant business value. This value starts with the implementation of ISO 50001-Energy management system standard, which provides an internationally-relevant framework for integration of energy management into an organization’s business processes. The resulting structure emphasizes effective use of available data and supports continual improvement of energy performance. International relevance is particularly important for companies with a global presence or trading interests, providing them with access to supporting ISO standards and a growing body of certified companies representing the collective knowledge of communities of practice. This paper examines the business value of SEP, a voluntary program that builds on ISO 50001, inviting industry to demonstrate an even greater commitment through third-party verification of energy performance improvement to a specified level of achievement. Information from 28 facilities that have already achieved SEP certification will illustrate key findings concerning both the value and the challenges from SEP/ISO 50001 implementation. These include the facilities’ experience with implementation, internal and external value of third-party verification of energy performance improvement; attractive payback periods and the importance of SEP tools and guidance. US DOE is working to bring the program to scale, including the Enterprise-Wide Accelerator (SEP for multiple facilities in a company), the Ratepayer-Funded Program Accelerator (supporting tools for utilities and program administrators to include SEP in their program offerings), and expansion of the program to other sectors and industry supply chains.

    2014-01-01

    Full Text Available Superior mesenteric artery syndrome is a rare condition that causes a proximal small intestinal obstruction due to contraction of the angle between the superior mesenteric artery and the aorta. Scoliosis surgery is one of the 15 reasons for superior mesenteric artery syndrome, which can present with acute or chronic manifestations. Although conservative treatment is usually possible, surgical treatment is required in certain cases that cannot be treated using conservative methods. In this paper, we describe a patient who developed superior mesenteric artery syndrome after scoliosis surgery and was treated with duodenojejunostomy due to failure and complications of conservative treatment.

    The 13.1-Moz high-sulfidation epithermal gold deposit of Lagunas Norte, Alto Chicama District, northern Peru, is hosted in weakly metamorphosed quartzites of the Upper Jurassic to Lower Cretaceous Chimú Formation and in overlying Miocene volcanic rocks of dacitic to rhyolitic composition. The Dafne and Josefa diatremes crosscut the quartzites and are interpreted to be sources of the pyroclastic volcanic rocks. Hydrothermal activity was centered on the diatremes and four hydrothermal stages have been defined, three of which introduced Au ± Ag mineralization. The first hydrothermal stage is restricted to the quartzites of the Chimú Formation and is characterized by silice parda, a tan-colored aggregate of quartz-auriferous pyrite-rutile ± digenite infilling fractures and faults, partially replacing silty beds and forming cement of small hydraulic breccia bodies. The δ34S values for pyrite (1.7-2.2 ‰) and digenite (2.1 ‰) indicate a magmatic source for the sulfur. The second hydrothermal stage resulted in the emplacement of diatremes and the related volcanic rocks. The Dafne diatreme features a relatively impermeable core dominated by milled slate from the Chicama Formation, whereas the Josefa diatreme only contains Chimú Formation quartzite clasts. The third hydrothermal stage introduced the bulk of the mineralization and affected the volcanic rocks, the diatremes, and the Chimú Formation. In the volcanic rocks, classic high-sulfidation epithermal alteration zonation exhibiting vuggy quartz surrounded by a quartz-alunite and a quartz-alunite-kaolinite zone is observed. Company data suggest that gold is present in solid solution or micro inclusions in pyrite. In the quartzite, the alteration is subtle and is manifested by the presence of pyrophyllite or kaolinite in the silty beds, the former resulting from relatively high silica activities in the fluid. In the quartzite, gold mineralization is hosted in a fracture network filled with coarse alunite

Se enfoca el estudio espacial jerárquico desde diferentes escalas de análisis: micro, meso y macroescala. La macroescala (macroecositema equivale a los biomas de Mendoza, (Altos Andes y Monte; la mesoescala, a los ecosistemas definidos por la diferenciación geomorfológica (mesoecosistema; y la microescala, a los sub-ecosistemas que surgen de las diferenciaciones topográficas y edáficas vinculadas con las formaciones vegetales y su ambiente (microecosistema. Para este trabajo se aplican los métodos: geográfico y el de factores de control, ambos conducen el análisis y la identificación de los ecosistemas. Las diferenciaciones jerárquicas espaciales de los ecosistemas están basadas en: el clima zonal, las unidades geomorfológicas que lo modifican; la topografía y el suelo con su disponibilidad de agua, modificadores del microclima. Los objetivos generales se basan en la identificación y localización de los ecosistemas jerárquicos y su análisis multiescalar integrado. Las hipótesis planteadas afirman que, en las escalas de ecosistemas, el clima es el denominador común que organiza la distribución de los mismos; y que existen agentes degradadores en todos los niveles de análisis. En el análisis, se aplican los métodos deductivo-inductivos vinculando las escalas jerárquicas de los ecosistemas y los estudios de casos.

    Full Text Available This paper is aimed at studying the relationship between large rural estates (haciendas and encomiendas in northern Argentina (Jujuy and the establishment of order in the countryside by te State in the second half of the nineteenth century. Even though encomiendas had been abolished in Argentina by Republican legislation at the beginning of that century, an interesting and anachronistic debate developped in Jujuy on the continuity of encomienda and the rights it bestowed upon land ownership. This debate was resolved by the Federal Justice which gave to the provincial State the chance of exerting its control on vast rural areas as well as benefitting from the eventual sale of fiscal lands. The State’s policies favoured the reconstitution of haciendas and, with few exceptions, hindered the peasants’ access to land ownership.

    El presente trabajo estudia la relación entre la hacienda y la encomienda en el norte argentino (Jujuy y el establecimiento del orden rural por parte del estado en la segunda mitad del siglo XIX. Si bien las encomiendas habían sido abolidas en Argentina por la legislación republicana a comienzos de ese siglo, en Jujuy se dio un interesante y anacrónico debate sobre la continuidad de la encomienda y los derechos que otorgaba a la propiedad de la tierra. Este debate fue resuelto por la justicia federal, que abrió la posibilidad al Estado provincial de ejercer su autoridad sobre vastas regiones rurales y, eventualmente, obtener recursos de la venta de tierras fiscales. La política estatal benefició la reconstitución de las haciendas y, con escasas excepciones, frenó el acceso de los campesinos a la propiedad de la tierra.

    Full Text Available La responsabilidad social surge en la literatura del siglo XIX y desde entonces ha ganado una mayor expresión, atención e interés de los estudiosos, empresarios y público en general, debido a su impacto en particular. Por lo tanto, la responsabi- lidad social ha tenido en las últimas décadas una fuerte expansión que ha llevado a su aplicabilidad en la estrategia empresarial. Hoy, académicos y hombres de negocios van juntos tratando nuevas estrategias que incluyen nuevas variables en un estudio propiciado por la aparición de nuevas formas de actividad empresarial y por la creación de redes sociales. Ante esta nueva situación, el propósito de este artículo es comprobar si hay un impacto en la adopción de prácticas de respon- sabilidad social de las empresas de Maia y, en caso afirmativo, si afecta positiva o negativamente a la imagen corporativa de las empresas en el litoral norte de Portugal. Este artículo se estructura en dos secciones. La primera consiste en una revisión de la literatura sobre el tema, presentando el tema principal de los marcos conceptuales para el análisis. La segunda parte consiste en un estudio empírico que utiliza un análisis multivariado factorial que permite la activación de las primeras conclusiones sobre el impacto de la responsabilidad social en Portugal, sobre todo en las empresas objeto de estudio. Se encontró en el estudio que la práctica de la responsabilidad social crea impacto en las acciones de las empresas, pero no se produce de manera significativa en sus resultados económicos.

    Full Text Available The aim of this study was to evaluate the composition and quality of raw milk that was refrigerated in tanks, according to the farm structures, bovine diet, and production levels of the dairy producers that provide milk for the Association of Small-Scale Ranchers of the Angicos Wilderness (ASRAW. Data were collected from 47 dairy farmers from different cities of the state of Rio Grande do Norte who are associated with ASRAW. Twenty-three tanks were sampled throughout the month of June 2013, with two collections per week and five samples per tank, for a total of 920 samples. The properties were characterized according to the type of tank (private or community, the food provided during milk collection (voluminous or voluminous and concentrated, the structure of the dairy producer (family producer or non-family producer, and the amounts of each component. Analyses of fat content, total protein, casein levels, lactose levels, total solids, degreased dry extract (DDE, freezing point, urea levels, somatic cell counts (SCC, and antibiotic residues were performed. Statistical analyses were conducted for each group, and the means were compared by Tukey tests, with a critical significance level of 5% probability calculated with the PROC GLM procedure of the SAS® program. Most components differed significantly for each parameter. The highest difference was noted between the urea and SCC levels, which was probably due to the wide variety of dairy producer profiles. The SCC values exhibited the largest amplitude variations. Most milk components significantly differed according to the strata, producer, food, and tank. These changes probably had little influence on the animal’s physiology and productivity. Therefore, despite the small variations in the components of the milk supplied by ASRAW, the different types of milk storage tank, milk volume produced, and type of dairy producer affected the overall milk quality.

    Superior vena cava syndrome (SVCS) is a clinical expression of obstruction of blood flow through the superior vena cava. The patterns of the Doppler flow changes of superior vena cava (SVC), especially the respiratory effects on them have not yet been fully elucidated. This study was to examine SVC Doppler flow patterns and the respiratory effects on them in healthy subjects and patients with SVCS. The SVC Doppler flow patterns of 18 normal human subjects and 22 patients with SVCS were analyzed at initial diagnosis and were followed up every 2 months for at least 11 months. Among the 22 patients, 5 patients with the tumor near the right atrium oppressing the inferior segment of the SVC had clear VR- and AR-waves, while in the other 17 patients the VR- and AR-waves disappeared or their outlines were vague. The respiratory variations of the S- and D-waves as a percentage change in inspiration compared to expiration in patient group were much lower than those in control group (S-wave: 1.67 +/- 3.32% vs. 15.65 +/- 16.15%, P = 0.0003; D-wave: 1.80 +/- 1.12% vs. 23.55 +/- 37%, P = 0.0087), which gradually became larger with treatment and showed no significant difference with those in control group after 7 months. The Doppler flows of the patients with SVCS correlate well with the images of CT scan of them. The respiratory variation of the S- and D-velocities could be used to evaluate the severity of SVC obstruction and its therapeutic effect.

    Full Text Available Los marcadores genéticos del pelaje y malformaciones óseas han permitido caracterizar el perfil genético de más de 400 poblaciones del gato doméstico alrededor del mundo. Hace 15 años se estableció dicho perfil en la ciudad de Cali (Colombia. En este estudio se determinó si el norte y sur de Cali se comportan como subpoblaciones y se comparó el perfil total con el estudio pasado. Se encontró una disminución de la frecuencia alélica de a ( no-agouti y d ( dilution , pero un aumento en cinco, especialmente en l ( longhair y c s ( siamese . Dichas diferencias pueden atribuirse a la selección humana de características más atractivas y por el flujo génico resultante del crecimiento demográfico de la ciudad, lo que explicaría también el primer reporte de los alelos inhibitor y ticked abyssinian . Se evaluó el equilibrio Hardy-Weinberg para el norte, sur y las dos zonas juntas, usando los loci white spotting y orange , encontrándose desequilibrio en este último para las tres zonas evaluadas debido a un déficit de heterocigotos. Norte y sur se dividieron en dos, y cada sub-muestra presentó equilibrio Hardy-Weinberg, aunque las diferencias en las frecuencias alélicas y heterocigosidades resaltaron microestructura geográfica y una relación entre tiempo de fundación del barrio y heterocigosidad. Norte y sur resultaron ser una población y no subpoblaciones (F ST = 0,0004, D= 0,0017, al igual que las nueve poblaciones colombianas con las que se comparó la presente ciudad. Se sugiere realizar un análisis microgeográfico de flujo génico y la definición de posibles colonias de gatos en Cali.

    Full Text Available A existência de ciclos ou periodicidades, aparentes nas séries temporais longas de variáveis meteorológicas, auxilia no entendimento dos processos físicos que controlam o clima e os ciclos identificados, eventualmente, servem como prognosticadores do clima regional. Com essa motivação, foi aplicado o filtro de Hodrick-Prescott (HP às séries dos índices de Oscilação Sul (IOS e Oscilação do Atlântico Norte (OAN no período 1900-2010. O filtro HP, aplicado a uma série temporal longa, gera duas novas séries, uma contendo os sinais da tendência e a outra, os da parte cíclica/aleatória da variável. Posteriormente, cada uma das séries foi submetida à análise das transformadas de ondeletas de Morlet para identificação dos ciclos aparentes. A série da tendência dos IOS apresentou ciclos de 6, 9, 17 e 28 anos, o primeiro associado ao Ciclo El Niño/La Niña, os dois seguintes possivelmente ao Ciclo Nodal Lunar (Ciclo Saros de 18 anos e o último, à Oscilação Decadal do Pacífico (ODP. A série da tendência de OAN apresentou ciclos de 6, 9 e 33 anos, os dois últimos possivelmente relacionados ao Ciclo Saros. Os coeficientes de correlação linear entre a série cíclica/aleatória do IOS, adiantado de 6 meses, e a precipitação no Brasil apresentaram valores altos, de até 0,72 e -0,67 para áreas do Norte e Sul do País, respectivamente, no período 1948-1999 (52 anos, com nível de significância superior a 99%. Esse período cobre as duas fases da ODP. Considerando que os modelos de clima ainda não apresentam destreza adequada para previsão regional no Brasil, sugere-se que a previsão de clima, utilizando a série cíclica/aleatória do IOS adiantado de até 6 meses, seja explorada e, eventualmente, validada.

La mezcla de CaCO3 + MgO aumentó significativamente el contenido de Mg intercam- biable, siendo el efecto más marcado con la dosis de 3 t ha-1. La respuesta de la cal se presentó en forma lineal en los 4 años de cosecha evaluados, con un incremento en el rendimiento de fruta y sólidos solubles al elevarse la dosis. El tratamiento de 3 t ha-1 de cal presentó el rendimiento más alto con los 3 materiales evaluados en las 4 cosechas, lo que indica la posibilidad de obtener respuesta a una dosis mayor. No hubo diferencias significativas entre las 3 fuentes de cal en las variables de suelo y rendimiento, lo que indica que las variaciones en calidad química y física de los materiales no afectaron los resultados. Sin embargo, la mezcla CaCO3 + MgO presentó el valor más bajo de acidez, el más alto de Mg en el suelo y en las hojas, y los rendimientos más altos de fruta y sólidos solubles.

  12. Modelling distributed ablation on Juncal Norte Glacier, dry Andes of central Chile

    In the Aconcagua River Basin, in the dry Andes of central Chile, water resources in summer originate mostly from snow and ice glacier melt. Summer seasons are dry and stable, with precipitation close to zero, low relative humidity and very intense solar radiation. The region's economic activities are dependent on these water resources, but their assessment is still incomplete and an effort is needed to evaluate present and future changes in water from glacier and seasonal snow covers in this area. The main aim of this paper is to simulate glacier melt and runoff from Juncal Norte Glacier, in the upper Aconcagua Basin, using models of various complexity and data requirement. We simulate distributed glacier ablation for two seasons using an energy-balance model (EB) and an enhanced temperature-index model (ETI). Meteorological variables measured at Automatic Weather Stations (AWSs) located on and off-glacier are extrapolated from point observations to the glacier-wide scale. Shortwave radiation is modelled with a parametric model taking into account shading, reflection from slopes and atmospheric transmittance. In the energy-balance model, the longwave radiation flux is computed from Stefan-Boltzmann relationships and turbulent fluxes are calculated using the bulk aerodynamic method. The EB model includes subsurface heat conduction and gravitational redistribution of snow. Glacier runoff is modelled using a linear reservoir approach accounting for the temporal evolution of the system. Hourly simulations of glacier melt are validated against ablation observations (ultrasonic depth gauge and ablation stakes) and runoff measured at the glacier snout is compared to a runoff record obtained from a combination of radar water level measurements and tracer experiments. Results show that extrapolation of meteorological input data, and of temperature in particular, is the largest source of model uncertainty, together with snow water equivalent initial conditions.

    Full Text Available RESUMO A antracnose é uma das principais doenças pós-colheita em bananas. O trabalho teve como objetivos avaliar, durante dez meses, a intensidade da antracnose e o efeito da lavagem e sanitização das frutas no controle da doença em pós-colheita de bananas. O experimento foi realizado de setembro de 2013 a junho de 2014. As coletas dos frutos foram realizadas, mensalmente, em cinco propriedades comerciais localizadas nos municípios de Jaíba, Janaúba e Nova Porteirinha, cultivadas com banana ‘Prata-Anã’. As pencas foram subdivididas em buquês de três frutos, o delineamento experimental foi o inteiramente casualizado em esquema fatorial e submetidos aos tratamentos: frutos sem a realização da lavagem (testemunha; frutos lavados na propriedade; frutos lavados no laboratório com hipoclorito de sódio a 2%; frutos lavados no laboratório com hipoclorito de sódio a 2% seguido de aplicação com fungicida Imazalil. As avaliações foram realizadas em 10 épocas e os tratamentos repetidos cinco vezes. Calculou-se área abaixo da curva de progresso da intensidade (AACPI e área abaixo da curva de progresso da severidade (AACPS. Os resultados obtidos foram submetidos à análise de variância e as médias comparadas através do teste de Scott-Knott, a 5% de probabilidade. A maior intensidade de antracnose em bananas no Norte de Minas ocorre nos meses de novembro de 2013 a março de 2014. A menor intensidade ocorre nos meses de setembro e outubro de 2013 e abril a junho de 2014. Nos meses de novembro a março, época de maior intensidade de doença, a lavagem dos frutos com detergente neutro e hipoclorito de sódio a 2% seguida de aplicação do fungicida Imazalil é a técnica mais eficiente de controle. A lavagem dos frutos, apenas com detergente neutro pode favorecer o aparecimento de antracnose, pela degradação da cutícula.

    Full Text Available A maioria das espécies não descritas de fungos é esperada em áreas pouco estudadas, como as florestas tropicais ou habitats pouco explorados como fungos que vivem em insetos, plantas, ou liquens. O Filo Ascomycota apresenta o maior número de espécies dentro do Reino Fungi, sendo que cerca da metade destas espécies são liquenizadas, ou seja, associam-se a algas e/ou cianobactérias e formam os liquens. Estes fungos liquenizados, de maneira geral, têm sido muito pouco estudados no Norte e Nordeste brasileiros, no que diz respeito à sua taxonomia e ecologia. Recentemente, estudos mais completos sobre a diversidade de liquens em remanescente de Mata Atlântica e em algumas áreas da Amazônia resultaram no registro de uma grande quantidade de espécies novas para a ciência, reforçando a importância de uma caracterização mais acurada da biodiversidade de uma área para favorecer à sua conservação. No âmbito do projeto Sisbiota, foi realizado um extenso inventário de espécies de liquens corticícolas crostosos e microfoliosos no estado de Rondônia, representando a Floresta Amazônia, e no estado de Sergipe, que apresenta apenas pequenos remanescentes de Mata Altântica. Os resultados obtidos evidenciam a riqueza destas duas áreas, nas suas devidas proporções, visto que em ambas foi encontrado um número significativo de novas espécies para ciência, com 75 espécies publicadas para Rondônia, e 10 espécies novas para Sergipe. Com isso, atualmente, o número de espécies conhecidas para Rondônia passou de 31 para 502, sendo apresentados aqui 104 novos registros para o estado, sendo 10 novos registros para o Brasil e sete para o hemisfério sul.

El ser humano ha sido capaz de adaptarse a estos microambientes optimizando sus asentamientos para poder aprovechar los recursos que se encuentran en cada uno de éstos. Este trabajo se enfoca en la zona costera del centro-norte de Yucatán y su trayectoria hacia el interior, donde linealmente se puede hallar una sucesión de tales nichos y donde con base en la información arqueológica obtenida mediante varios proyectos de prospección y salvamento arqueológico en la región, se pueden identificar diferencias importantes en el patrón de asentamiento y las características de las  estructuras. Dichos datos a la vez, brindan la pauta para comprender el tipo de relaciones que los habitantes de la zona mantuvieron con el entorno y la forma como se han adaptado a través del tiempo.

    Full Text Available O presente trabalho objetiva investigar o emprego do conceito de memória no processo criativo do romance Cinzas do Norte, de Milton Hatoum. São estabelecidas relações entre a vida do autor e a sua obra, a partir do conceito de “biografema” estabelecido por Roland Barthes. Relações entre vivência, memória, esquecimento e invenção serão abordadas, assim como diálogos entre literatura, memória, corpo e História contemporânea do Brasil. A estrutura do enredo de Cinzas do Norte reflete a perspectiva de trabalhos fragmentários com a memória. A mescla entre cartas, relatos e foco narrativo reconfiguram modalidades mais tradicionais do gênero memorialístico. Todavia, o discurso ainda se prende a um posicionamento ligado, em última instância, à voz do narrador, responsável este por reorganizar os diversos textos e gêneros que se alternam no livro.

    Full Text Available Molecular findings that confirmed the participation of ovine herpesvirus 2 (OVH-2 in the lesions that were consistent with those observed in malignant catarrhal fever of cattle are described. Three mixed-breed cattle from Rio Grande do Norte state demonstrated clinical manifestations that included mucopurulent nasal discharge, corneal opacity and motor incoordination. Routine necropsy examination demonstrated ulcerations and hemorrhage of the oral cavity, corneal opacity, and lymph node enlargement. Significant histopathological findings included widespread necrotizing vasculitis, non-suppurative meningoencephalitis, lymphocytic interstitial nephritis and hepatitis, and thrombosis. PCR assay performed on DNA extracted from kidney and mesenteric lymph node of one animal amplified a product of 423 base pairs corresponding to a target sequence within the ovine herpesvirus 2 (OVH-2 tegument protein gene. Direct sequencing of the PCR products, from extracted DNA of the kidney and mesenteric lymph node of one cow, amplified the partial nucleotide sequences (423 base pairs of OVH-2 tegument protein gene. Blast analysis confirmed that these sequences have 98-100% identity with similar OVH-2 sequences deposited in GenBank. Phylogenetic analyses, based on the deduced amino acid sequences, demonstrated that the strain of OVH-2 circulating in ruminants from the Brazilian states of Rio Grande do Norte and Minas Gerais are similar to that identified in other geographical locations. These findings confirmed the active participation of OVH-2 in the classical manifestations of sheep associated malignant catarrhal fever.

    Anomalies of systemic venous return are extremely heterogeneous congenital malformations with variable ranges from completely normal physiology to severe forms of right to left shunting requiring surgical treatment. Anomalous drainage of a right-sided superior vena cava (SVC) to the left atrium (LA) is one of the rarest variants of systemic venous return anomalies, characterized by right-to-left shunt physiology and cyanosis. Here we report a 2 years old girl presented with cyanosis which was observed shortly after birth by her parents but not further investigated. She is otherwise active girl and with normal growth and development. Her clinical examination was unremarkable apart from mild clubbing of the fingers and low oxygen saturation of 88-90% in room air. Her ECG and chest X-ray were unremarkable. Echocardiography showed bilateral SVC connected by a small innominate vein. The right SVC drains directly into the LA while the left SVC drains into the right atrium (RA) via a dilated coronary sinus. There is a small superior sinus venosus type atrial septum defect (ASD) with left to right shunt. Also, there is partial anomalous pulmonary venous return with right upper and right middle pulmonary veins draining directly into the right SVC, which is connected to LA. The right lower pulmonary vein and left pulmonary veins drain directly to LA. The rest of her echocardiography demonstrated normal heart structures and function. This patient was referred for surgical correction, including baffling of the right SVC to the RA and closure of the ASD. We describe this case to highlight the importance of recognizing this rare anomalous systemic venous connection as one of the very rare causes of cyanosis in the pediatric age group as well as at older age.

    Full Text Available El presente artículo es resultado de una investigación que tuvo como propósito conocer el impacto de un modelo pedagógico para el desarrollo de competencias en educación superior (DECOES en el logro de la competencia para intervenir en grupos sociales vulnerables a partir de la solución de problemas. El modelo DECOES se diseñó a partir de la reflexión crítica de profesores y alumnos al identificar problemas y sugerir soluciones. Dicho modelo consta de fundamentos psicopedagógicos y socio filosóficos; además incluye aspectos sobre cómo establecer la relación y la práctica pedagógica. Se aplicó a los alumnos del segundo semestre de la Licenciatura en Intervención Educativa en una universidad pública del norte de México con un diseño cuasiexperimental. Para ello se utilizó un grupo experimental y uno control. En el experimental se utilizó una guía didáctica en la que se concretó el modelo. En el grupo control se desarrolló la práctica pedagógica tal como el profesor del grupo la tenía planeada en la que los alumnos solo exponían proyectos de intervención ya diseñados y aplicados por diversas instituciones. La competencia se evaluó mediante un esquema de pretest - postest. Se encontró que no existen diferencias significativas entre el grupo control y el experimental en el pretest; mientras que en el postest sí existen diferencias significativas entre ambos grupos. Se infiere que el modelo pedagógico DECOES tuvo efectos en el grupo experimental al favorecer el logro de la competencia.

Del mismo modo, la implementación de estos programas en formatos virtuales es también creciente. En este trabajo se compara la satisfacción de un mismo programa de entrenamiento en estrategias de estudio y autorregulación implementado en dos formatos, presencial y virtual, con el objetivo de observar si existe alguna diferencia entre ambas metodologías. Para ello se cuenta con una muestra de 370 alumnos de una universidad del norte de España. Los resultados sugieren una mayor efectividad del programa llevado a cabo en formato virtual. Se discuten los resultados partiendo de la controversia existente entre el potencial motivador de los entornos virtuales y las dificultades que pueden añadir al proceso de aprendizaje de los alumnos.

    Quantum information systems are expected to exhibit superiority compared with their classical counterparts. This superiority arises from the quantum coherences present in these quantum systems, which are obviously absent in classical ones. To exploit such quantum coherences, it is essential to control the phase information in the quantum state. The phase is analogue in nature, rather than binary. This makes quantum information technology fundamentally different from our classical digital information technology. In this paper, we analyse error sources and illustrate how these errors must be managed for the system to achieve the required fidelity and a quantum superiority. This article is part of the themed issue 'Quantum technology for the 21st century'.

    The right superior vena cava draining into the left atrium is a rare malformation causing cyanosis and clubbing in patients in whom no other signs of congenital heart defect are present. Diagnosis may be difficult as cyanosis may be mild and the anomaly is not always easily detectable by echocardiography. For this reason we report a 13-month-old male in whom we confirmed the clinical and echocardiographic suspicion of anomalous drainage of the right superior vena cava using multidetector CT. This allowed successful surgical reconnection of the right superior vena cava to the right atrium. (orig.)

Los municipios están agrupados en nueve clases de tamaño urbano y en tres regiones: norte, centro, sur. En términos generales, se observan patrones de localización consistentes con los modelos que existen en la geografía económica. Los servicios superiores se concentran en las zonas urbanas más grandes, exhibiendo un patrón jerárquico. La industria, particularmente la de tecnología media, está relativamente más concentrada en ciudades de tamaño medio. Pero México muestra también ciertas particularidades: los servicios financieros están proporcionalmente muy concentrados en la capital; la desconcentración de la industria es aún limitada. La proximidad con los Estados Unidos genera una lógica espacial particular en el norte, diferente de la del centro y del sur.The location of employment in manufacturing and in high-order services in México is examined using location quotients. Municipalities are grouped into nine urban size classes and three regions: north, centre, and south. Location patterns are generally consistent with models in economic geography. High-order services concentrate in the largest urban areas, exhibiting a hierarchical pattern. Manufacturing, especially mid-tech manufacturing, is relatively more concentrated in medium-sized cities. México also exhibits distinctive features: financial services are proportionately very concentrated in the capital; industrial deconcentration is still limited. The proximity of the US generates a distinctive spatial logic in the North, different from that in the Centre and the South.

    A newborn boy presented within the first day of life with moaning, anemia, and thrombocytopenia. The clinical syndrome resulted from thrombosis of the posterior part of the superior sagittal sinus due to impression at birth of the tip of the occipital squama. Both computed tomography and ultrasound scans were valuable noninvasive tools for documentation of the thrombus itself and the cerebral sequelae. Color Doppler ultrasound scan confirmed the absence and reappearance of flow in the superior sagittal sinus.

    Superior memorizers often employ the method of loci (MoL) to memorize large amounts of information. The MoL, known since ancient times, relies on a complex process where information to be memorized is bound to landmarks along mental routes in a previously memorized environment. However, functional magnetic resonance imaging data on groups of trained superior memorizer are rare. Based on the memorizing strategy reported by superior memorizers, we developed a scheme of the processes successively employed during memorizing and recalling digits and relate these to brain activation that is specific for the encoding and recall period. In the examined superior memorizers several regions, suggested to be involved in mental navigation and digit-to-word processing, were specifically activated during encoding: bilateral early visual cortex, retrosplenial cortex, left parahippocampus, left visual cortex, and left superior parietal cortex. Although the scheme suggests that some steps during encoding and recall seem to be analog, none of the encoding areas were specifically activated during the recall. Instead, we found strong activation in left anterior superior temporal gyrus, which we relate to recalling the sequential order of the digits, and right motor cortex that may be related to reciting the digits.

    The superior pedicle mammaplasty is a technique frequently employed in the treatment of breast ptosis, associated or not with hypertrophy of the gland, followed by satisfactory results. This technique is normally not indicated in severe breast ptosis (pendulous breast) because of the excessive length of the pedicle supplying nipple-areola-complex (NAC), with the risk of ischemia. In these cases the standard technique is the free-nipple-graft mammaplasty. However, the deepen knowledge about vascular anatomy of the breast and the aptitude to perform superior pedicle mammaplasty, induced the authors to indicate this technique even in these cases improving the aesthetic and functional outcomes. The authors present a series of 30 patient with pendulous breasts, with sternal notch-nipple distance equal or superior to 32 cm (45 cm maximum; mean value 35.1), treated with the superior pedicle mammaplasty with inverted "T" scar. The results confirm the reliability of superior pedicle for the nipple-areolar complex blood supply, associated with satisfactory aesthetic results due especially to the good breast projection. They conclude that superior pedicle technique mammaplasty, even if normally not indicated in these cases, is instead suitable for the treatment of pendulous breasts with great sternal notch-nipple distance, permitting to take advantages of this technique.

    Full Text Available A persistência da veia cava superior esquerda com ausência da veia cava superior direita é uma anomalia rara, com menos de 150 casos descritos na literatura. A não-obliteração e regressão da veia cardinal anterior esquerda durante o desenvolvimento embriológico promove uma variação sistêmica de retorno venoso ao coração, com persistência da veia cava superior esquerda. Sua incidência varia de 0,3% em pacientes sem alterações cardíacas congênitas concomitantes a 4,3% naqueles com cardiopatias. Na maioria das vezes coexiste a veia cava superior direita, porém se houver regressão e degeneração da veia cardinal anterior direita, implicará a sua ausência e a drenagem venosa para o coração será feita pela veia cava superior esquerda ao átrio direito, através do seio coronariano. Mostramos um caso de um paciente submetido a radiografia de tórax e tomografia computadorizada para avaliação de doença pulmonar obstrutiva crônica, tendo como achado a persistência da veia cava superior esquerda com ausência da direita, sem qualquer cardiopatia associada e com a drenagem cardíaca sendo feita, através do seio coronariano, para o átrio direito.Persistent left superior vena cava with absent right superior vena cava is a rare anomaly, with less than 150 cases reported in the literature. Congenitally persistent left superior vena cava is the most common variant of systemic venous return to the heart, resulting embryologically from failure of the left anterior cardinal vein to become obliterated. Its incidence varies from 0.3% in patients with otherwise normal heart to 4.3% in patients with congenital heart disease. In the majority of the patients, a right superior vena cava is present as well, but rarely the right anterior cardinal vein degenerates resulting in the absence of the normal right superior vena cava. The blood from the right side is carried by the persistent left superior vena cava to the right atrium through the

    este se han dado en otras partes del globo terraqueo y es precisamente la intencion de este articulo mostrar como puede aplicarse en el caso de Mexico el arreglo acordado sobre el Mar del Norte. Las caracteristicas bilaterales de este arreglo conformado por incentivos y aperturas al mercado, requieren de la cooperacion de diferentes oficinas y sectores gubernamentales del gobierno federal para hacer posibles una serie de estipulaciones que regulen el trato y permitan a distintas empresas petroleras una interaccion sustanciosa que reditue para los duenos de ambas fronteras. En Mexico la responsabilidad de echar a andar proyectos de este tipo corresponde al poder legislativo en complicidad con las secretarias de asuntos externos y del trabajo. Los actuales modelos de accion y el monopolio Petroleos Mexicanos (PEMEX) en Mexico solo han logrado estancar el desarrollo del pais en este sector y mantener el desarrollo petrolifero en un nivel mediocre y deteriorado. Los beneficios de un tal arreglo se extenderian mas alla de lograr un desarrollo bilateral para los paises involucrados; sin embargo, recordemos que el gobierno de los Estados Unidos no esta al compas de los gobiernos pro-unificacion de fronteras. Para comenzar la unificacion de las regiones fronterizas Mexico debe documentar la ubicacion de los pozos fronterizos, sin embargo aun cuando se llegara a algun acuerdo deberan pasar anos antes que PEMEX desarrolle la tecnologia apropiada para explotar su parte de los yacimientos.

The present study aimed to investigate the presence of Babesia spp., Ehrlichia spp., Anaplasma spp., Hepatozoon spp. and Leishmania spp. in blood samples and ticks, collected from two dogs from Rio Grande do Norte showing suggestive tick-borne disease by using molecular techniques. DNA of E. canis, H. canis and L. infantum were detected in blood samples and R. sanguineus ticks collected from dogs. Among all samples analyzed, two showed the presence of multiple infections with E. canis, H. canis and L. infantum chagasi. Here we highlighted the need for molecular differential diagnosis in dogs showing nonspecific clinical signs.

    The first topographic and ice-motion maps of the northwestern flank of Hielo Patagonico Norte (HPN, northern Patagonia Icefield), in Chile, were produced using satellite synthetic-aperture interferometric radar data acquired by NASA's Spaceborne Imaging Radar C instrument in October 1994. The topographic map has a IO m vertical precision with a 30 m horizontal spacing, which should be sufficient to serve as a reference for monitoring future mass changes of the icefield. The ice-motion map is accurate to within 4 mm/ d (or 1/ ma). The radar-derived surface topography and ice velocity are used to estimate the ice discharge from the accumulation area of four outlet glaciers, and the calving flux and mass balance of Glaciar San Rafael. The results demonstrate the use of SAR interferometry for monitoring glaciological parameters on a spatial and temporal scale unattainable by any other means.

    Full Text Available The aim of this study is to identify factors that relate to the judgment of political parties accountability operating in the state of Rio Grande do Norte. Twenty-four political parties with directory in the state were selected considering those who have had their accounts judged between 2006 to 2013. In order to determine which factors are related to the trial of party accounts, logistic regression were considered for the analysis. Independent variables were the total revenues received by the party (in logarithm, dummy for political parties with or without the resources of the party fund and dummy for years that there were state elections, while the trial of the accounts of parties (approval / disapproval is dependent variable. The results show that only the dummy's Party Fund positively influence the judgments of the annual accounts parties. Thus, it is understood that the parties receiving public funds are more likely to provide better information and, therefore, have its accounts approved by the Unidade Técnica do Tribunal Regional Eleitoral do Rio Grande do Norte. Moreover, one can even say that the parties receiving such government help have a trend or an indication of concern with the concept of accountability, since the party fund is a public resource. It is recommended that future studies address other indicators, for example, liquidity, debt and profitability. Moreover, as also proxies related to the disclosure of financial statements, number of persons elected by party in relation to the number of candidates and party members number could become plausible indicators for future research that would use the same methodology. In addition, replicate this metodology to other states for comparative issues, and even use the same methodology at national level could be aspects of research to be worked for the future.

    Full Text Available α-Thalassemia, arising from a defect in a-globin chain synthesis, is often caused by deletions involving one or both of the a-genes on the same allele. With the aim of investigating the prevalence of α-thalassemia 3.7 kb deletion in the adult population of Rio Grande do Norte, 713 unrelated individuals, between 18 and 59 years-of-age, were analyzed. Red blood cell indices were electronically determined, and A2 and F hemoglobins evaluated by HPLC. PCR was applied to the molecular investigation of α-thalassemia 3.7 kb deletion. Eighty (11.2% of the 713 individuals investigated presented α-thalassemia, of which 79 (11.1% were heterozygous (-α3.7/αα deletions and 1 (0.1% homozy- gous (-α3.7/-α3.7. Ethnically, heterozygous deletions were higher (24.8% in Afro-Brazilians. Comparison of hemato- logical parameters between individuals with normal genotype and those with heterozygous α+-thalassemia showed a statistically significant difference in the number of erythrocytes (p < 0.001, MCV (p < 0.001, MCH (p < 0.001 and Hb A2 (p = 0.007. This study is one of the first dedicated to investigating α-thalassemia 3.7 kb deletion in the population of the State Rio Grande do Norte state. Results obtained demonstrate the importance of investigating this condition in order to elucidate the causes of microcytosis and hypochromia.

    Full Text Available Abstract Background Human communities consistently develop a detailed knowledge of the therapeutical and medicinal properties of the local flora and fauna, and these folk remedies often substitute medicines produced by the pharmaceutical industry. Animals (and their derived products are essential ingredients in the preparation of many traditional remedies. The present work prepared an inventory of the animals sold in public markets in the cities of Crato and Juazeiro do Norte, Ceará State, Brazil. Methods Information was obtained through the use of semi-structured questionnaires in interviews held with 27 merchants of medicinal animals (18 in the municipality of Juazeiro do Norte [11 men and 7 women] and 9 people in the municipality of Crato [6 men and 3 women]. We calculated the Informant Consensus Factor (ICF to determine the consensus over which species are effective for particular ailments, as well as the species Use Value (UV to determine the extent of utilization of each species. Results A total of 31 animal species, distributed among 21 families were identified as being used medicinally. The taxa most represented were: insects (8 species, mammals (7, fish (5, reptiles (5 and birds (4. The animals sold in these markets are used to treat a total of 24 ailments, with rheumatism, asthma, and inflammations having the largest numbers of citations. Three species not previously reported as having medicinal use were encountered: Leporinus steindachneri (utilized for treating cholesterol problems, Gryllus assimilis (utilized in treating urinary infections, and Phrynops tuberosus (used to treat asthma, rheumatism and bruises. Conclusion The composition of the local fauna, the popular culture, and commercial considerations are factors that maintain and drive the market for therapeutic animal products – and the lack of monitoring and regulation of this commerce is worrisome from a conservationist perspective.

Foram examinadas 365 amostras de soro sanguíneo de cães atendidos na rotina de diversas clínicas veterinárias durante o período de março a novembro de 2011. O diagnóstico sorológico da leptospirose foi realizado pela técnica de soroaglutinação microscópica (SAM, utilizando-se 24 sorovares de Leptospira spp. como antígenos. Dos 365 cães, 25 foram soropositivos para pelo menos um dos sorovares de Leptospira spp., com frequência de 6,8%. Os sorovares com reações sorológicas mais frequentes foram Shermani (40%, Sentot (36% e Copenhageni (20%. O perfil epidemiológico da leptospirose canina na região metropolitana de Natal, estado do Rio Grande do Norte, indica que a infecção ocorre com frequência baixa em comparação com outras regiões, provavelmente devido ao grande percentual de animais vacinados, bem como, sugere-se distribuição homogênea de animais soropositivos na região. Por outro lado, a presença de roedores pode ser um importante fator de risco, uma vez que sorovares mantidos por estes animais foram identificados entre os mais frequentes.

Comparam-se também o volume desses recursos para Roraima com os destinados outros Estados da Região Norte. Foram analisados os recursos disponibilizados para o Estado e a efetividade do seu emprego, ante as potencialidades sinalizadas para os 15 municípios de Roraima. Investigou-se o baixo nível de absorção desses recursos destinados para investimentos ao longo dos cinco anos abrangidos pela pesquisa. O suporte teórico do estudo envolveu as idéias sobre círculo vicioso da pobreza e teoria da base econômica. No período, apenas R$ 163 milhões foram utilizados, dos R$ 666 milhões disponibilizados (25% do total. Entre as causas dessa baixa absorção estão: ausência física da presença do Banco em 87% dos municípios; falta de regularização fundiária; centralização do poder decisório das operações fora do Estado; excesso de burocracia na apreciação dos pleitos; carência de bons projetos; deficiência no gerenciamento dos projetos; falta de iniciativa e desconhecimento da existência desses recursos. Mesmo assim, em 2008, cada real do fundo aplicado em Roraima expandiu o PIM em R$ 1,25, gerando 0,14 novos empregos.

    Full Text Available Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone conduction hyperacusis, and pulsatile tinnitus. The initial series of patients were diagnosed based on common symptoms, a physical examination finding of eye movements in the plane of the superior semicircular canal when ear canal pressure or loud tones were applied to the ear, and high-resolution computed tomography imaging demonstrating a dehiscence in the bone over the superior semicircular canal. Research productivity directed at understanding better methods for diagnosing and treating this condition has substantially increased over the last two decades. We now have a sound understanding of the pathophysiology of third mobile window syndromes, higher resolution imaging protocols, and several sensitive and specific diagnostic tests. Furthermore, we have a treatment (surgical occlusion of the superior semicircular canal that has demonstrated efficacy. This review will highlight some of the fundamental insights gained in SCDS, propose diagnostic criteria, and discuss future research directions.

    2014-01-01

    Full Text Available Importance. Superior semicircular canal dehiscence (SCD is a third window lesion of the inner ear causing symptoms of vertigo, autophony, tinnitus, and hearing loss. A “two-hit” hypothesis has traditionally been proposed, whereby thinly developed bone overlying the superior canal is disrupted by a sudden change in intracranial pressure. Although the symptoms of SCD may be precipitated by head injury, no previous reports have described a temporal bone fracture directly causing SCD. Observations. Two patients sustained temporal bone fractures after closed head trauma, and developed unilateral otologic symptoms consistent with SCD. In each instance, computed tomography imaging revealed fractures extending through the bony roof of the superior semicircular canal. Conclusions and Relevance. Temporal bone fractures, which are largely treated nonoperatively, have not previously been reported to cause SCD. As it is a potentially treatable entity, SCD resulting from temporal bone fracture must be recognized as a possibility and diagnosed promptly if present.

    Recent research indicates that some elderly persons experience an age-related visual processing deficit, for which they may attempt to compensate through the use of relational information. This hypothesis was tested, using the category superiority effect as a model system. In studies of young adults, the category superiority effect has been shown to be confined to relatively abstract stimulus materials such as verbal items, and to be absent for more concrete representations such as photographs of actual objects. However, it was predicted that, contrary to the data from young adults, a category superiority effect would be present in elderly adults for both verbal and pictorial stimuli, because elderly people would be expected to use category information to compensate for imageric deficits. This prediction was confirmed, consistent with the hypothesis.

    Quantum information systems are expected to exhibit superiority compared with their classical counterparts. This superiority arises from the quantum coherences present in these quantum systems, which are obviously absent in classical ones. To exploit such quantum coherences, it is essential to control the phase information in the quantum state. The phase is analogue in nature, rather than binary. This makes quantum information technology fundamentally different from our classical digital information technology. In this paper, we analyse error sources and illustrate how these errors must be managed for the system to achieve the required fidelity and a quantum superiority.This article is part of the themed issue 'Quantum technology for the 21st century'. © 2017 The Author(s).

    2004-01-01

    The shortjaw cisco (Coregonus zenithicus) was historically found in Lakes Huron, Michigan, and Superior, but has been extirpated in Lakes Huron and Michigan apparently as the result of commercial overharvest. During 1999-2001, we conducted an assessment of shortjaw cisco abundance in five areas, spanning the U.S. waters of Lake Superior, and compared our results with the abundance measured at those areas in 1921-1922. The shortjaw cisco was found at four of the five areas sampled, but abundances were so low that they were not significantly different from zero. In the four areas where shortjaw ciscoes were found, abundance declined significantly by 99% from the 1920s to the present. To increase populations of this once economically and ecologically important species in Lake Superior, an interagency rehabilitation effort is needed. Population monitoring is recommended to assess population trends and to evaluate success of rehabilitation efforts.

    Full Text Available Pyomyositis is a primary bacterial infection of striated muscles nearly always caused by Staphylococcus aureus. Development of the intramuscular abscess involving the extra-ocular muscles (EOMs remains an extremely rare process. We herein present a case of isolated EOM pyomyositis involving superior rectus muscle in a 2-year male child who was referred with complaints of swelling in left eye (LE and inability to open LE since last 1-month. Orbital computed tomography (CT scan showed a well-defined, hypo-dense, peripheral rim-enhancing lesion in relation to left superior rectus muscle suggestive of left superior rectus abscess. The abscess was drained through skin approach. We concluded that pyomyositis of EOM should be considered in any patient presenting with acute onset of orbital inflammation and characteristic CT or magnetic resonance imaging features. Management consists of incision and drainage coupled with antibiotic therapy.

    Full Text Available There is a tight relationship between information assurance, the intelligence cycle and information superiority within NATO operations. The intelligence cycle has a discrete architecture and provides on-time and relevant intelligence products to the joint force commanders and to other authorized users in a specifi c joint area of operations. The intelligence cycle must follow the evolution of the operation. A permanent intelligence estimate will be performed during the military decision making process and operations execution. Information superiority is one of the most powerful intelligence cycle achievements. and decisively infuences the success of NATO joint operations. Information superiority must be preserved and enhanced through information assurance. Information assurance is an information operation that must be planned by the military in charge of operation security or by non-military experts, executed by all personnel during the entire intelligence cycle life time and employed during the planning and execution of NATO joint operations.

    Full Text Available Data suggests that individuals with schizophrenia (SZ and superior intelligence can present without specific neurocognitive deficits. However, neurocognitive decrements, defined as worse cognition than expected, have been reported in practically all schizophrenia cases. This study investigated if neurocognitive decrements are present in intellectually superior SZ by comparing the neuropsychological profile of SZ cases with IQ-matched healthy controls (HC across intellectual level. Participants with SZ and HCs were stratified into three IQ-groups; intellectually low (IQ 80-95; SZ n = 65 & HC n = 13, intellectually normal (IQ = 100-115; SZ n = 111 & HC n = 115 and intellectually superior (IQ > 120; SZ n = 20 & HC n = 50. A repeated measures multivariate analysis of co-variance compared performance on eight selected neuropsychological tests across IQ-strata and diagnostic group. Differences in clinical characteristics and social functioning in SZ across IQ-strata were investigated with multivariate and univariate analyses of variance. Intellectually superior SZ participants scored within normal limits, but had neurocognitive decrements compared to superior HCs. Decrements were of the same magnitude as in the low and normal IQ-strata. Levels of functional impairments and clinical characteristics in participants with SZ did not differ significantly across IQ-strata. Results indicate that neurocognitive decrements are present in intellectually superior SZ to the same extent as in intellectually low and intellectually normal SZ, supporting the notion that SZ is a neurocognitive disorder. Similar levels of social functional deficits and clinical symptoms suggest similar disease processes in SZ across intellectual level.

We will describe the case of a 34-year-old with cerebral palsy who presented with abdominal pain, nausea, vomiting, and weight loss and was diagnosed with SMA syndrome via CT-imaging. With failure of conservative measures, our patient underwent a duodenojejunostomy after which improvement in her weight as well as relief of her abdominal symptoms was noted. Given the rarity of this syndrome, physicians need to keep a high index of suspicion in order to prevent the damaging consequences.

    2017-05-01

    Superior sulcus tumors have posed a formidable therapeutic challenge since their original description by Pancoast and Tobias in the early twentieth century. Initial therapeutic efforts with radiotherapy were associated with high rates of relapse and mortality. Bimodality therapy with complete surgical resection in the 1960s paved the way for trimodality therapy as the current standard of care in the treatment of superior sulcus tumors. The evolution of treatment approaches over time has provided outcomes that come increasingly closer to rivaling those of similarly staged nonapical lung cancer. Copyright © 2017 Elsevier Inc.

  16. The superiorly based bilobed flap for nasal reconstruction.

    2018-02-01

    The laterally based bilobed flap is commonly used for the reconstruction of small- to medium-sized defects of the distal portion of the nose; However, when this flap is used to repair defects that are larger, more cephalic, or more lateral on the nose, there is a risk for lower nasal distortion. Reorienting the base superiorly preserves the advantages of the traditional design while minimizing this risk. To demonstrate the design, execution, and efficacy of the superiorly based bilobed flap. A retrospective review examined all superiorly based bilobed flaps performed by 1 surgeon (J.C.) in 2000-2016 after tumor extirpation by Mohs micrographic surgery at a single institution. A total of 41 surgical defects were closed with 40 flaps between June 2000 and August 2016 (1 patient had 2 defects closed with a single flap). Of the tumors, 55% were located on the nasal dorsum, and the median of the longest postoperative tumor axis was 1.4 cm. Follow-up was available for 40 flaps, and no infections, hematomas, or episodes of full-thickness necrosis were observed. Data were collected retrospectively from a single institution without a standardized assessment tool for aesthetic outcomes. The superiorly based bilobed flap is useful for nasal reconstruction.

    The aim of this study is trying to describe more details of superior mesenteric artery margin in pancreaticoduodenectomy for pancreatic ductal adenocarcinoma, to evaluate biological and prognostic implications of tumor budding in this margin, and to provide more evidence for evaluation of R0 surgery in pancreaticoduodenectomy. 46 patients in 5-years period are included in this study. Immunochemistry and immunofluorescence are used to analyze tumor budding and epithelial-mesenchymal transition. Superior mesenteric artery margin might be described from four aspects including location, gross appearance, microscopic appearance and tumor budding. We find that 1mm rule for R1 surgery is more appropriate to predict prognosis (P = 0.009) than 0mm rule (P = 0.141). Expression of cytokeratin in tumor budding is significantly lower than primary tumor (P = 0.001), and it suggests that tumor budding may participate the procedure of epithelial-mesenchymal transition. High-grade tumor budding and decreasing cytokeratin of tumor budding correlate with distant metastasis and has negative influence on prognosis. So superior mesenteric artery margin might be not only an area that tumor cells may invade, but also a pathway for distant metastasis. It is necessary to evaluate superior mesenteric artery margin in pancreaticoduodenectomy for pancreatic cancer.

    Full Text Available Corea del Norte supone una amenaza para la paz y seguridad internacionales no sólo como consecuencia de sus programas de armas nucleares y de misiles sino también y sobre todo de la transferencia de tales ingenios. En el marco de tal transferencia la relación del estado del nordeste de Asia con Pakistán merece ser objeto de especial atención. El artículo, en ese sentido, analiza los intercambios en materia nuclear y de misiles entre Pakistán y Corea del Norte y la situación a corto-medio plazo en relación con las transferencias norcoreanas.

  15. [Examination of the hypothesis 'the factors and mechanisms of superiority'].

    Science.gov (United States)

    Sierra-Fitzgerald, O; Quevedo-Caicedo, J; López-Calderón, M G

    INTRODUCTION. The hypothesis of Geschwind and Galaburda suggests that specific cognitive superiority arises as a result of an alteration in development of the nervous system. In this article we review the co existence of superiority and inferiority . PATIENTS AND METHODS. A study was made of six children aged between 6 and 8 years old at the Instituto de Belles Artes Antonio Maria Valencia in Cali,Columbia with an educational level between second and third grade at a primary school and of medium low socio economic status. The children were considered to have superior musical ability by music experts, which is the way in which the concept of superiority was to be tested. The concept of inferiority was tested by neuropsychological tests = 1.5 DE below normal for the same age. We estimated the perinatal neurological risk in each case. Subsequently the children s general intelligence and specific cognitive abilities were evaluated. In the first case the WISC R and MSCA were used. The neuropsychological profiles were obtained by broad evaluation using a verbal fluency test, a test using counters, Boston vocabulary test, the Wechster memory scale, sequential verbal memory test, super imposed figures test, Piaget Head battery, Rey Osterrieth complex figure and the Wisconsin card classification test. The RESULTS showed slight/moderate deficits in practical construction ability and mild defects of memory and concept abilities. In general the results supported the hypothesis tested. The mechanisms of superiority proposed in the classical hypothesis mainly involve the contralateral hemisphere: in this study the ipsilateral mechanism was more important.

    To investigate neuropathological changes in the superior colliculus in chronic traumatic encephalopathy. The densities of the tau-immunoreactive neurofibrillary tangles, neuropil threads, dot-like grains, astrocytic tangles, and neuritic plaques, together with abnormally enlarged neurons, typical neurons, vacuolation, and frequency of contacts with blood vessels, were studied across the superior colliculus from pia mater to the periaqueductal gray in eight chronic traumatic encephalopathy and six control cases. Tau-immunoreactive pathology was absent in the superior colliculus of controls but present in varying degrees in all chronic traumatic encephalopathy cases, significant densities of tau-immunoreactive neurofibrillary tangles, NT, or dot-like grains being present in three cases. No significant differences in overall density of the tau-immunoreactive neurofibrillary tangles, neuropil threads, dot-like grains, enlarged neurons, vacuoles, or contacts with blood vessels were observed in control and chronic traumatic encephalopathy cases, but chronic traumatic encephalopathy cases had significantly lower mean densities of neurons. The distribution of surviving neurons across the superior colliculus suggested greater neuronal loss in intermediate and lower laminae in chronic traumatic encephalopathy. Changes in density of the tau-immunoreactive pathology across the laminae were variable, but in six chronic traumatic encephalopathy cases, densities of tau-immunoreactive neurofibrillary tangles, neuropil threads, or dot-like grains were significantly greater in intermediate and lower laminae. Pathological changes were not correlated with the distribution of blood vessels. The data suggest significant pathology affecting the superior colliculus in a proportion of chronic traumatic encephalopathy cases with a laminar distribution which could compromise motor function rather than sensory analysis.

    Full Text Available INTRODUÇÃO: Em virtude de sua fácil acessibilidade, o cinema parece influenciar bastante a imagem que a sociedade faz da Psiquiatria. OBJETIVO: Realizar uma revisão sistemática da literatura sobre o retrato da Psiquiatria pelos cinemas norte-americano e brasileiro. MÉTODOS: Sem limite de data, fez-se uma busca bibliográfica manual e nos seguintes bancos de dados: LILACS, MedLine, PsychLit, PsycINFO e SciELO. Usaram-se as seguintes combinações de descritores em inglês e, nas bases LILACS e SciELO, os correspondentes em português: "psychiatry" E/OU "motion pictures as topic". Estipularam-se critérios precisos de inclusão e exclusão. RESULTADOS: Vinte artigos indexados e dois livros. No cinema norte-americano, tais fontes evidenciaram um constante retrato estereotipado de diferentes aspectos da Psiquiatria, cuja imagem se mostrou ambivalente e com cinco fases distintas de sua representação. No cinema brasileiro, os escassos estudos se limitaram praticamente à fase de "Retomada" e mostraram que a maioria dos filmes apresentava algum conteúdo psicopatológico. DISCUSSÃO: Apesar da dificuldade de comparação entre as fontes encontradas, uma vez que quase todas eram descritivas, foi possível traçar um paralelo do retrato da Psiquiatria entre as películas dos Estados Unidos e as nacionais. CONCLUSÃO: A representação da Psiquiatria difere bastante entre os cinemas norte-americano e brasileiro, sobretudo pela amostra de os filmes analisados abrangerem períodos bem distintos.INTRODUCTION: As cinema has an easy accessibility, it seems to influence society's image of psychiatry.

    Full Text Available O presente trabalho traz uma discussão sobre o ensino experimental da disciplina de Física no estado do Rio Grande do Norte. A Física é, em sua essência, uma ciência experimental, embora a realidade das salas de aula brasileiras tende a demonstrar o contrario, pautando a disciplina em conceitos estanques e um formalismo matemático excessivo. Felizmente, têm-se observado uma mudança desse cenário em âmbito nacional, e verificou-se nesse trabalho se o Rio Grande do Norte acompanha essa tendência. Para isso, foram elaborados dois momentos de análise distintos. No primeiro, Verificou-se a existência da prática experimental nas escolas de ensino médio. Para esse quesito, analisaram-se as escolas com os melhores indicadores IDEB. Por fim, um questionário foi elaborado e levado aos alunos de cursos de Licenciatura em Física, em diferentes cidades do Estado. Nesse momento, a aplicação do questionário distinguiu alunos da licenciatura em Física em ingressantes, concluintes e alunos cursando alguma disciplina de Física Experimental. Por fim, os resultados foram analisados e discutidos, mostrando uma evolução do ensino no Rio Grande do Norte, e uma prática experimental crescente e motivadora

    2012-02-01

    To compare the surgical results in patients with congenital superior oblique palsy treated with inferior oblique recession (IOR) versus those treated additionally with superior oblique tendon tuck (IOR+SOT). A consecutive, nonrandomized series of patients with congenital superior oblique palsy with vertical deviations in adduction between 10° and 20° were retrospectively reviewed. In the first series, patients were treated with IOR; in the second series, patients were treated with IOR+SOT. We examined the effects of surgery on binocular alignment and on the field of binocular single vision. Each group consisted of 20 patients. Preoperative ocular deviations were similar in both groups. Postoperative residual vertical deviations were not different in the primary position or in downgaze; however, significantly better alignment was achieved in the IOR+SOT group in adduction and downgaze in adduction. Consecutive Brown pattern occurred in 18 of 20 patients who underwent IOR+SOT versus 5 of 20 who underwent IOR. Residual torsion was not statistically different. The field of binocular single vision improved to 92% (range, 28%-100%) after IOR and to 96% (range, 64%-100%) after IOR+SOT (P = 0.20). IOR alone is a suitable procedure for most congenital superior oblique palsies with a moderate-to-large vertical deviation in adduction, resulting in a lower incidence of consecutive Brown pattern than with IOR+SOT.

Nesse contexto, as agências de proteção ambiental vêm despendendo esforços para o estabelecimento de índices que possam identificar áreas suspeitas de contaminação. Valores de Referência de Qualidade para Solos (VRQs refletem a concentração natural de determinada substância no solo, sem interferência antrópica. O trabalho objetivou estabelecer os VRQs para os metais Ag, Ba, Cd, Co, Cr, Cu, Ni, Pb, Sb, V e Zn exigidos pelo Conama, para composição da legislação direcionada ao monitoramento desses elementos nos solos do Estado do Rio Grande do Norte. Foram coletadas 416 amostras de solo em áreas de mata nativa ou com mínima influência antrópica. A abertura das amostras foi efetuada pelo método EPA-3051A, sendo os metais determinados por espectrometria de emissão ótica (ICP-OES e absorção atômica (AA. Os resultados do trabalho comprovaram que estudos regionalizados são essenciais para definição de VRQs. Os VRQs calculados para o Rio Grande do Norte foram mais restritivos que os de outros estados do país. A análise fatorial de confirmação dos dados foi útil para obtenção de VRQs mais confiáveis e demonstrou que para o Estado esses valores podem ser estabelecidos com apenas duas repetições por local de coleta. Nesse sentido, é primordial um planejamento prévio, de distribuição dos locais de amostragem, de maneira que os diversos compartimentos geomorfológicos, pedológicos e geológicos do Estado sejam representados.

Using a new type of marking and by focal sampling, one colony was observed from September 2007 to September 2008. It was determined that the social structure in the colony is integrated by four groups, which did not vary in structure over time. It was established that females were more faithful to the shelter than males. We assessed time budget day and there was that individuals have a 73.9 % time without any activity, followed by grooming with a 26.6 %, and females had higher activity than males, especially in dry season. We found that C. brevicauda  has differences with records of C. perspicillata such as the fidelity of females and non-influence of lunar light over the hour of emergence from the refuge. ORGANIZACIÓN SOCIAL DE UNA COLONIA DEL MURCIÉLAGO EN UN REFUGIO ARTIFICIAL, BOCHALEMA, NORTE DE SANTANDER, COLOMBIASe estudió la organización social de una colonia del murciélago frugívoro Carollia brevicauda en un refugio artificial en Bochalema, Norte de Santander, Colombia.

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

    Full Text Available The city of Londrina (north of Paraná State emancipated politically on December 10, 1934, five years after the arrival of the pioneers of the Companhia de Terras Norte do Paraná (CTNP - mostly English owned company that began colonization in 1929. In October 1934, two months before being elevated to the status of municipality, was born the first communication vehicle in the city, the newspaper Paraná-Norte. Present from the beginning, the press reported on its pages the transformations that city suffered through the years, being a document of important historical value. This study therefore aims to analyze the beginning of the trajectory ofLondrina's press from the place occupied by the image in the pages of the city's first newspaper, Paraná-Norte (1934-1953 and the magazine A Pioneira (1948-1954. To understand the importance of photography published in such vehicles as trace for writing the history ofLondrina, it employed some research methodologies. The first was the literature, followed by the documentary analysis (MOREIRA, 2009 for all editions of the newspaper and magazine available to the public consultation, which allowed to write about the history of the two media pioneers. Already a comparative study of photography in Paraná-Norte and A Pioneira was done by iconographic analysis, proposed by Kossoy (2001. Faced with the impossibility of studying the universe of photographs published by two journals, we chose to select, via random draw, one copy per year of circulation newspaper and magazine. Thus, the study focused on 18 editions of Paraná-Norte (for the years 1951 and 1952 there are no copies available and 7 of the magazine A Pioneira. Drawing on theoretical frameworks that deal with interfaces between story and image, press photography and memory, portraits and family albums, we conclude that, although the use of imagery has been explored differently by the two vehicles, even because of difficulties technical and financial, in

    Coastlines around the world are under ever-increasing pressure due to population trends, commerce, and geophysical processes like tropical storms and erosion. This multi-institutional field campaign was conducted to improve our understanding of complex nearshore processes under varying forcing conditions on a microtidal, sandy beach located in Sisal, Yucatan from 3/27 to 4/12/2014. Hydrodynamics, morphodynamics, and textural variability were investigated during: (1) a cold front event (referred to as El-Norte); (2) land breeze (LB); and (3) sea breeze (SB). The instrumentation layout included three surf/swash zone cross-shore transects where water elevation, suspended sediment concentration, bed load, and current velocities were measured, as well as several offshore ADCP for hydrodynamic measurements. TKE, τb, ɛ and were estimated using the data obtained from surf zone ADV. In addition, Hs and Tsin the surf zone were computed using measurements from ADV pressure sensors, while a separate pressure transducer was used to obtain water free-surface elevation within the swash zone. During SB cycles the study area experienced wind velocities reaching up to 12ms-1, and 15ms-1 during El-Norte. Elevated wind stress during El-Norte resulted in Hs of 1.5m and 0.6m in water depths of 10m and 0.4m, respectively. Surface sediment grab samples during SB/LB cycles showed that the swash zone had a moderately well sorted distribution with a mean grain size of 0.5mm, while poor sorting and a mean grain size of 0.7mm were found during El-Norte. Additionally, measured bathymetry data showed evidence for offshore sandbar migration during strong offshore currents (0.4ms-1) during El-Norte, while onshore sandbar migration was evident during SB/LB periods (0.3ms-1 and 0.1ms-1, respectively). This study highlights how different weather forcing conditions affect hydrodynamics, morphodynamics, and textural variability on a sandy beach. Aside from furthering our knowledge on these complex

Una de ellas es Eucalyptus cladocalyx, que además está siendo considerada en programas de hibridación interespecífica para mejorar características como la tolerancia al déficit hídrico. 49 genotipos (familias de medio hermanos, provenientes de seis poblaciones, fueron evaluadas a los 30 meses después de la plantación, en dos localidades del semiárido Chileno: Caracas y Tunga. Cada uno de los ensayos tuvo un diseño de bloques completos al azar, con parcelas de un árbol, con 30 bloques. Se estimaron componentes de varianza por el método de máxima verosimilitud restringida (REML en un modelo lineal mixto. Se obtuvieron los valores genéticos a través de la mejor predicción lineal no sesgada (BLUP del efecto aleatorio debido al origen (poblaciones. A pesar de que el cálculo de la heredabilidad fue conservador al considerar un coeficiente k = 2,5, las heredabilidades de la altura fueron moderadas y altas, con valores desde 0,48 en Caracas, a 0,76 en Tunga. Los valores de la heredabilidad para el diámetro basal fueron moderados, variando desde 0,26 a 0,39 en Caracas y Tunga, respectivamente. Los orígenes de Cowell, Remarkable e Illapel, mostraron valores genéticos negativos en ambos sitios. Por otro lado, la procedencia de Wirrabara obtuvo siempre valores genéticos superiores al resto, mostrando ser una procedencia interesante para el programa de mejoramiento de la especie. Si los valores de heredabilidad permanecen en el tiempo, permitiría obtener importantes ganancias genéticas, y con ello mejorar significativamente la productividad de las futuras plantaciones de Eucalyptus cladocalyx.

    The recent identification of highly superior autobiographical memory (HSAM) raised the possibility that there may be individuals who are immune to memory distortions. We measured HSAM participants’ and age- and sex-matched controls’ susceptibility to false memories using several research paradigms. HSAM participants and controls were both susceptible to false recognition of nonpresented critical lure words in an associative word-list task. In a misinformation task, HSAM participants showed higher overall false memory compared with that of controls for details in a photographic slideshow. HSAM participants were equally as likely as controls to mistakenly report they had seen nonexistent footage of a plane crash. Finding false memories in a superior-memory group suggests that malleable reconstructive mechanisms may be fundamental to episodic remembering. Paradoxically, HSAM individuals may retrieve abundant and accurate autobiographical memories using fallible reconstructive processes. PMID:24248358

    Full Text Available A double belly composition of piriformis muscle with superior gluteal nerve entrapment between the two muscle masses was detected. Piriformis muscle and its relation to sciatic nerve has been suggested as a cause of piriformis syndrome. Patients suffering from buttock pain are most often diagnosed as having piriformis syndrome, where anatomical variation of the piriformis is an important contributor. The present variation showed two distinct bellies of piriformis muscle. Interestingly the superior gluteal nerve was interposed between the two bellies. Such incidental findings on cadavers may help the clinicians to establish a rare yet important cause of piriformis syndrome. Furthermore, such observations are also relevant to the radiologists while interpreting MRI scans in cases of undiagnosed chronic gluteal pain.

    Tullio phenomenon refers to eye movements induced by sound.(1) This unusual examination finding may be seen in superior semicircular canal dehiscence (SSCD) syndrome.(2) This disorder is due to absent bone over the superior semicircular canal (figure). Patients complain of dizziness triggered by loud sound, aural fullness, autophony, and pulsatile tinnitus. When Tullio phenomenon exists in SSCD syndrome, the patient develops a mixed vertical-torsional nystagmus in which the slow phase rotates up and away from the affected ear (video on the Neurology® Web site at Neurology.org). This pattern of nystagmus aligns in the plane of the dehiscent semicircular canal and is due to excitation of its afferent nerves.

    The form change paradigm was used to explore the basis for the picture superiority effect. Recognition memory for studied pictures and words was tested in their study form or the alternate form. Form change cost was defined as the difference between recognition performance for same and different form items. Based on the results of Experiment 1 and previous studies, it was difficult to determine the relative cost for studied pictures and words due to a reversal of the mirror effect. We hypothesized that the reversed mirror effect results from subjects' basing their recognition decisions on their assumptions about the study form. Experiments 2 and 3 confirmed this hypothesis and generated a method for evaluating the relative cost for pictures and words despite the reversed mirror effect. More cost was observed for pictures than words, supporting the distinctiveness model of the picture superiority effect.

    Highly Superior Autobiographical Memory (HSAM) is characterised as the ability to accurately recall an exceptional number of experiences and their associated dates from events occurring throughout much of one's lifetime. The source of this ability has only begun to be explored. The present study explores whether other enhanced cognitive processes may be critical influences underlying HSAM abilities. We investigated whether enhanced abilities in the domains of verbal fluency, attention/inhibition, executive functioning, mnemonic discrimination, perception, visual working memory, or the processing of and memory for emotional details might contribute critically to HSAM. The results suggest that superior cognitive functioning is an unlikely basis of HSAM, as only modest advantages were found in only a few tests. In addition, we examined HSAM subjects' memory of the testing episodes. Interestingly, HSAM participants recalled details of their own experiences far better than those experiences that the experimenter shared with them. These findings provide additional evidence that HSAM involves, relatively selectively, recollection of personal, autobiographical material.

    Full Text Available Toxoplasmosis is caused by Toxoplasma gondii, which is the main causative agent of abortion in small ruminants. Goats are among the animals that are most susceptible to this protozoon, and the disease that it causes leads to significant economic losses and has implications for public health, since presence of the parasite in products of goat origin is one of the main sources of human infection. Because of the significant economic impact, there is an urgent need to study the prevalence of T. gondii infection among goats in Sertão do Cabugi, which is the largest goat-producing region in Rio Grande do Norte. In the present study, the ELISA assay was used to test 244 serum samples from nine farms, located in four different municipalities in the Sertão do Cabugi region, which is an important goat-rearing region. The results showed that the prevalence of anti-T. gondii antibodies was 47.1% and that there was a significant association between positivity and the variables of age (≥ 34 months, location (Lajes, Angicos and Afonso Bezerra and farm (all the farms. The avidity test was applied to all the 115 ELISA-positive samples to distinguish between acute and chronic infection. One hundred and three samples (89.6% displayed high-avidity antibodies, thus indicating that most of the animals presented chronic infection, with a consequent great impact on the development of the goat production system and a risk to human health.

    Full Text Available Potato late blight (Phytophthora infestans, is this crop's most important disease in Colombia. An alternative in reducing the high dependence on fungicides to control the potato late blight includes developing resistant plant varieties, such as the ones recently delivered in Colombia (Pastusa Suprema and Esmeralda, which show high acceptance levels among growers. However, maintenance of resistance in these materials, as well as the effectiveness of systemic fungicides used to control this disease depends on management practices and evolutionary dynamics of P. infestans in each of the potato-growing regions. This research evaluated such a condition through a population structure study of isolates obtained from the departments of Antioquia, Boyaca, Cundinamarca, and Norte de Santander, using AFLP (Amplified Fragment Length Polymorphism molecular markers. Results indicated the occurrence of low levels of genetic variability within each of the four populations and an important population differentiation among them, especially regarding the population of P. infestans from Antioquia against the middle-east populations. This suggests that besides the tests usually made in Cundinamarca and Boyaca to evaluate resistant materials for P. infestans, different tests in Antioquia should also be included.

    Full Text Available Objectives: To assess maternal mortality in Rio Grande do Norte, in the series 2003-2008, data from the Mortality Information System (SIM and the Committee on Maternal Mortality (MMR of the state. Methods: A descriptive study of population-based data on maternal mortality secondary collected by the SIM state through the program Tabwin, version 3.2, and CMM-RN, through the records and file reports. Results: We found that the percentage of maternal deaths investigated and confirmed by the Committee in relation to the registered on SIM ranged from 3% in 2003, decreasing to 1% in 2007, which is very small compared to total deaths of women in childbearing age in the period studied. Conclusions: It is possible to perceive weaknesses of the epidemiological surveillance of maternal deaths in the screening and a performance of the Committee in investigating these deaths far below those recorded in the on SIM, showing underreporting, data incompleteness and lack of consistency in the flow of information between these banks, making it impossible to compare the existing information. It is suggested that the Ordinances No. 1172/2004 and No 1119/2008 of the Ministry of Healthcare have to be complied, that surveillance supervises the registration of maternal death as an event of compulsory notification and that a punitive effect for municipalities that fail to comply with this protocol is established . These measures will help to reduce maternal mortality

    Frederico S. da Silva

    2010-01-01

    Full Text Available The aim of this study was to identify possible zonation patterns and assess the environmental impact on the Potengi River Estuary, Rio Grande do Norte State, through the distribution of benthic foraminifera associated to bacterial activity and abiotic parameters. Six sediment samples were collected from locations that presented clear signs of pollution. The environment was predominantly anaerobic and fermentation occurred at all sites. Forty-two species of foraminifera were identified. The dominant species were Ammonia tepida and Arenoparrella mexicana, which are known to be opportunistic, and able to adapt to rapidly changing conditions. CCA analyses showed that salinity and organic matter, followed by bacterial carbon, were more strongly linked to organism distribution in the Potengi River Estuary. Dissolved oxygen concentration, temperature and total organic matter were higher at the estuary mouth than at the other sites, creating favorable conditions for foraminiferal growth and allowing the faunistic succession on the upper estuary. As foraminifera assemblages when associated to environmental parameters can be used as efficient proxies for environmental diagnosis, these results suggest that the Potengi Estuary is under great stress from the surrounding urban development.

    Serra da Borborema, in Northeast Brazil, along the border of the states of Rio Grande do Norte and Paraiba, is known for comprising thousands of pegmatitic bodies and it is called Borborema Pegmatite Province. The pegmatites are exploited for gems and non-metallic ores and also for metallic by-products. Many of these bodies are mined for radiominerals and radioactive minerals in so-called garimpos, illegal mines, with dangerous and insalubrious working conditions. In order to locate the sources of commercial batches of columbite-tantalite (coltan) ores, exported between 2000 and 2004, were made radiometric surveys in these mines in the region of the city of Parelhas and radioactive samples collected from the batches were analyzed for uranium, thorium, niobium, and tantalum. The gamma radiation was measured in the pegmatites, also from their enclosing rocks and from the surrounding soil. The results indicate that uraninite has been mixed with coltan ores, but these minerals themselves show considerable contents of uranium and thorium. Chemical analyses indicate four distinct trends for uranium, possibly correlated with previously and already observed four structural features which control the pegmatites, and also evidencing four magmatic-metasomatic events of their emplacement. Regarding the working conditions in the mines, the sparsely presence of uranium minerals does not necessarily represent a hazard for the workers. Laboring risks are much higher than any kind of radioactive risk. (author)

    A study on the distribution patterns of enteropathogenic bacteria polluting the shoreline in Natal, Rio Grande do Norte, Brazil, was carried out based on 72 samples obtained from three storm sewers and adjoining beach locations, Praia do Meio (PM), Areia Preta (AP) and Ponta Negra (PN). From each location, 12 water samples were taken and analyzed for fecal coliforms (FC) and Escherichia coli. In AP, two (16.7%) of the seawater samples and five (41.7%) of the storm sewer samples yielded values above 1.1 x 107 FC/100 ml, whereas only one (8.3%) of the samples from PM reached this level. There was no correlation (p > 0.05) between rainfall indices and FC values. A total of 64 E. coli isolates were obtained: 37 from the storm sewer samples and 27 from the seawater samples. Of these isolates, four (O143, two O112ac, and O124) were enteroinvasive and two (O111 and O125) were enteropathogenic. Resistance to antibiotics and to heavy metals was also analyzed. Almost 36% of the E. coli strains isolated were resistant to more than one antibiotic. All strains were resistant to zinc and copper at the highest concentration tested (250 microg/ml), and several (23.4%) were resistant to mercury at 50 microg/ml. Our results agreed with previous reports that antibiotic resistance is commonly associated with heavy-metal resistance in pathogens.

    Full Text Available Las expectativas mexicanas de inserción en los mercados globales, han sido puestas en las ciudades. Aunque frente a limitaciones de fondo, emerge el mercado de la imagen, uno de los renglones de mayor agresividad competitiva. En el escenario urbano, las interrogantes en torno al qué y cómo vender se anteponen por regla a políticas orientadas al bienestar social. En el ámbito particular de la Frontera Norte, formada por ciudades de crecimiento acelerado con ritmo sostenido a lo largo del siglo, tales preguntas parecen plantearse con mayor intensidad, a la par que el incremento de migrantes de paso. Así, los ambientes fronterizos se configuran mediante la proliferación obsesiva de toda oferta posible, para captar todo consumidor existente. Ante un consumidor en tránsito, de actitud compulsiva, el atractivo visual ha de ser único y contundente. Este empleo del espacio físico es una experiencia que tiende a ser trasladada territorio adentro, mediante un instrumento de intervención convincente: los megaproyectos urbanísticos. Las realizaciones en Tijuana, y luego las tentativas en Hermosillo y Culiacán, muestran operativos eficientes en el trastocamiento de formas urbanas.

    The presence of natural radioactive anomalies in rocks and soils of the state of Rio Grande do Norte may contribute to an increased exposure of the local population to natural radiation sources. From this region, there is a lack of information on the levels of natural radioactivity in drinking water supplies. Hence, this work focused on the characterization of the radiological and chemical aspects of the drinking water consumed in several municipalities of the Seridó Oriental region. Samples of surface water and groundwater were analysed for gross alpha and beta radioactivity and for the content of {sup 226}Ra. The most important physical and chemical parameters of the water are reported. Most of the monitored water parameter showed values higher than those recommended for a good organoleptic quality of the water. Gross alpha activity, ranging from <0.05 to 1.61 Bq/L, showed values higher than de permissible ones in two samples. Gross beta activity, corrected for {sup 40}K contribution, ranged from 0.22 to 1.67 Bq/L. The activity concentration of {sup 226}Ra ranged from <0.01 to 0.53 Bq/L. Water quality can be considered poor, taking into the high levels of dissolved solids, affecting mainly the organoleptic characteristics of the water. Further investigation is needed to assess the behavior of the radiometric parameter in those samples with values higher than the permissible ones and to extent the study to other municipalities of the region.

    The dengue viral infection is one of the most relevant vector-borne diseases in the world. The disease can manifest in a variety of forms, from asymptomatic to a condition of dengue hemorrhagic fever (DHF). The last reported cases in Brazil correspond to 80% of the cases reported in the Americas, which emphasizes the magnitude of the problem. This study was conducted using Geographic Information System (GIS) techniques, in order to evaluate the spatial distribution of the disease in the urban area of Mossoró, Rio Grande do Norte. In the period between 2001 and 2007, 867 new cases were listed. About 85.7% of the addresses were georeferenced, with a larger number of cases, 14.8%, in the neighborhoods of Santo Antônio and Santa Delmira (north region), and 11.7% in the neighborhoods of Conjunto Vingt-Rosado and Alto de São Manoel (east region). There were 18 confirmed cases of dengue hemorrhagic fever associated with regions with the highest incidence of classic cases of the disease. The use of Geographic Information System (GIS) proved a great benefit for better visualization of the endemic, especially in elucidating the actual distribution of dengue cases in the county and providing an effective tool for planning the monitoring of the disease at a local level.

    The ability of some plants to take up metal contaminants in the soil has been of increasing interest as an environmental approach to pollution clean-up. This study aimed to assess the ability of Pteris melanocaulon for copper(Cu) uptake by determining the Cu levels in the fern vis-à-vis surrounding soil and the location of Cu accumulation within its biomass. It also aimed to add information to existing literature as P. melanocaulon are found to be less documented compared to other fern metal accumulators, such as P. vittata. The P. melanocaulon found in the Suyoc Pit of a Copper-Gold mine in Placer, Surigao del Norte, Philippines exhibited a high Bioaccumulation Factor(BF) of 4.04 and a low Translocation Factor(TF) of 0.01, suggesting more Cu accumulation in the roots (4590.22 ± 385.66 µg g(-1) Cu). Noteworthy was the Cu concentration in the rhizome which was also high (3539.44 ± 1696.35 µg g(-1) Cu). SEM/EDX analyses of the Cu content in the roots indicated high elemental %Cu in the xylem (6.95%) than in the cortex (2.68%). The high Cu content in the roots and rhizomes and the localization of Cu in the xylem manifested a potential utilization of the fern as a metallophyte for rhizofiltration and phytostabilization.

    Gaucher's disease (GD) is caused by a β-glucocerebrosidase deficiency, leading to the accumulation of glucocerebroside in the reticuloendothelial system. The prevalence of GD in Tabuleiro do Norte (TN) (1:4000) is the highest in Brazil. The purpose of this study was to present evidence of consanguinity and founder effect for the G377S mutation (c.1246G>A) among GD patients in TN based on enzyme, molecular and genealogical studies. Between March 2009 and December 2010, 131 subjects at risk for GD (GC in dried blood ≤2.19 nmol/h/ml) and 5 confirmed GD patients from the same community were submitted for molecular analysis to characterize the genetic profile of the population. Based on the enzymatic and molecular analysis, the subjects were classified into three categories: affected (n = 5), carrier (n = 20) and non-carrier (n = 111). All carriers were (G377S/wt). Affected subjects were homozygous (G377S/G377S). The identification of a single mutation in carriers and homozygotes from different generations, the history of the community and the genealogy study suggest that the high prevalence of GD in this population may be due to a combination of consanguinity and founder effect for the G377S mutation. © 2014 John Wiley & Sons A/S.

Los trabajadores transfronterizos o commuters son los individuos que residen en alguna ciudad de la frontera norte de México, pero cotidianamente cruzan la línea fronteriza para trabajar en la ciudad estadounidense contigua. La información que se utiliza para realizar este estudio es la obtenida por el Censo de Población y Vivienda mexicano del año 2010; sin embargo, el análisis sobre el perfil de los commuters se complementa con información de carácter etnográfico producto de diversas entrevistas realizadas a los trabajadores transfronterizos, principalmente en las ciudades de Tijuana y Mexicali. Consideramos que esta población tiene una imagen individual y cotidiana más completa de la compleja relación que se da en la frontera México-Estados Unidos, dada su característica principal de interacción continua entre ambos lados de la frontera. Ello al mismo tiempo nos permite contar con una visión más profunda de una realidad fronteriza que se basa en la dependencia creada y recreada en las sociedades tanto mexicana como estadounidense.
