    The main purpose of this paper is to analyse the earliest work of Léon Rosenfeld, one of the pioneers in the search of Quantum Gravity, the supposed theory unifying quantum theory and general relativity. We describe how and why Rosenfeld tried to face this problem in 1927, analysing the role of his mentors: Oskar Klein, Louis de Broglie and Théophile De Donder. Rosenfeld asked himself how quantum mechanics should concretely modify general relativity. In the context of a five-dimensional theory, Rosenfeld tried to construct a unifying framework for the gravitational and electromagnetic interaction and wave mechanics. Using a sort of "general relativistic quantum mechanics" Rosenfeld introduced a wave equation on a curved background. He investigated the metric created by what he called `quantum phenomena', represented by wave functions. Rosenfeld integrated Einstein equations in the weak field limit, with wave functions as source of the gravitational field. The author performed a sort of semi-classical approximation obtaining at the first order the Reissner-Nordström metric. We analyse how Rosenfeld's work is part of the history of Quantum Mechanics, because in his investigation Rosenfeld was guided by Bohr's correspondence principle. Finally we briefly discuss how his contribution is connected with the task of finding out which metric can be generated by a quantum field, a problem that quantum field theory on curved backgrounds will start to address 35 years later.

  4. Léon Rosenfeld physics, philosophy, and politics in the twentieth century

    CERN Document Server

    Jacobsen, Anja Skaar

    2012-01-01

    This book is a social-intellectual biography of the Belgian physicist Léon Rosenfeld (1904-1974). Rosenfeld was at the center of modern theoretical physics and he became the Danish physicist Niels Bohr's right-hand man. Rosenfeld was a perceptive, polyglot cosmopolitan, whose life crossed those of many important people in many countries. He was also a strong integrated personality capable of performing exotic calculations at one moment, while disentangling subtle philosophical questions or intervening in a political discussion the next — all at the highest level. This book aims at a broad audience interested in contextual history of twentieth century physics. No specialized knowledge of physics is required to read it.

    2005-01-01

    Uranium was found in Mendoza in 1946 in 'Soberania' and 'Independencia' mines. After its creation in 1950 CNEA, together with Cuyo National University (UNC), developed the mining industry starting with the 'Papagayos' mine. It can be considered the beginning of the systematic exploitation of uranium in the country. In course of time the province of Mendoza passed to get one of the most uraniferous reserve of Argentina and it has accumulated the major production till now. However, in the last years there has been opposition to resume the production in the Sierra Pintada Uranium Manufacturing Complex. There was also a powerful land continuous progress in the field of no energetic applications of nuclear techniques in the province. The most outstanding example is the 'School of Nuclear Medicine Foundation', with installations in Mendoza city and in San Rafael. Besides, there is a research and development group in Cuyo National University devoted to the Nuclear Safety. Finally, we can not fail to mention the Auger Pierre Project, which is building in Malargue an observatory for the study of the cosmic rays. (author) [es

    Full Text Available The landscape is a perception of the agroecosystem valued as aesthetic, cultural, recreational and touristic, for conservation, among others. It is considered an environmental service and cultural heritage according to the International UN Conference 1972 (Paris, France. The agroecosystem of Mendoza's Northern Oasis creates a landscape with the presence of vineyards framed by the Andes, which is a scenic resource characterized as an environmental cultural service. The disordered process of urban growth in North of Mendoza, threatens the provision of the mentioned service. In this paper, a qualitative and a quantitative assessment aim to characterize the perceptions of urban residents on the vineyards landscape. Two methodologies were applied: expert opinion through focus groups and survey data collection. By working with focus groups, positive impacts of this kind of landscape were recognized. In the 638 surveys made in the urban area of Mendoza, a six landscape images valuation was requested (with a score of 1 to 10, where 10 is the maximum. The highest average scores were for the view of Aconcagua, secondly the agricultural landscape with vineyards and mountains and thirdly another view of vineyards in the North Oasis.

    Full Text Available Achieving the paradigm of sustainable urban mobility requires institutional capacities, appropriate policies and a regulatory framework that contains them. This work aims to contribute to the knowledge of the regulation of urban mobility in the metropolitan area of Mendoza. To this end, the current mobility regulations are assessed through indicators that are classified into three key areas: institutional and political organization, urban system and financial setup. The purpose is to account for the existence, or not, of regulatory capacities contained in the paradigm of sustainable mobility. Among the results, the absence of a policy of sustainable urban mobility is noteworthy, as well as the lack of sectorial coordination. Also of note is the absence of coordination between the urban planning system and the public transport provision. Lastly, in the financial sector, the results point to a promotion of sustainable transport modes but without such an explicit purpose.

    El Infiernillo porphyry copper and Mo deposit, in southern Mendoza, Argentina is hosted by ignimbrites of the Cochico Group (lower Permian). The alteration zone consists of a small central quartz neck with appreciable hematite surrounded by an intense quartz-injected zone with local pervasive potassic alteration. Outwards, there is a well-developed phyllic halo with intense bleaching which consists of pervasive and vein-type silicification, sericitization and pyritization. In the outer part of the alteration zone, small polymetallic veins with pyrite, arsenopyrite, galena and minor, chalcopyrite, sphalerite and electrum in quartz gangue crop out. New field, petro-mineralogic and geochemical data confirmed that the host rocks are equivalent to the dacitic and rhyodacitic ignimbrites of the Toba Vieja Gorda Member (Yacimiento Los Reyunos Formation, Cochico Group)

    Full Text Available Viticulture holdings of Mendoza Argentina, were classified by the allocation and the stratum size according to their total acreage based on the data of the last three National Agricultural Censuses (1988, 2002 and 2008. There are different behaviors in each stratum according to each growing zone. It has been observed that in all “oasis” smaller is the holding, higher is the rate of shrinkage. On the other hand the bigger sizes grow and the acreage concentration of these units has increased significantly. Behaviors were clustered according to their path: taking into account its relationship with both zonal and provincial level stratum averages. Areas like the Oasis Sur have suffered a major a regressive process that has involved almost all the strata. The Uco Valley has shown a significant dynamism in units of more than 25 ha, while the small holdings have moved back, but with lower rates than the average of these strata. The Oasis Norte has also been subject to a bipolar process where a significant loss of small vineyards with the rise of new big holdings. Oasis Este is the only one that remains with lower regression rates.

  4. Discovery of the Sierra Pintada uranium district, Mendoza Province, Argentina

    1981-01-01

    Since 1956, uranium-bearing minerals have been known to exist in Sierra Pintada, Mendoza Province, Argentina. Based on paragenetic considerations, a first radiometric prospection was carried out, leading to the discovery of two groups of anomalies (Puesto Agua del Toro and Cuesta de los Terneros), such as vein-type deposits, with uraninite and 'yellow minerals' and one sandstone-type deposit (Puesto La Josefa), related to sediments with carbon trash. Some recent geological research and surveys in the area, and a reduced drilling programme carried out on selected anomalies, led to reinterpretation of the potential of the area. Furthermore, and as a result of an airborne radiometric prospection performed in mid-1968, numerous anomalies have been discovered. The main constellation of anomalies, along the flanks of the El Tigre Brachyanticline, occurs in sandstones of Permian age. Explored by 80 000 m of drilling, they have shown the existence of several peneconcordant lens-shaped ore bodies of economic size, with uranophane on the surface and prevailing uraninite and some brannerite, coffinite and davidite below the water table. Reserves exceed 20 000 tonnes of U 3 O 8 . A new regional programme with a 4-km drill-grid initiated in 1978 led to the discovery of new ore bodies which are at present being evaluated. The alternatives and discontinuities during the development of the district, the prospecting and exploration techniques employed, and the results achieved in the different stages of the operation are discussed in detail. This case history attempts to illustrate the developing philosophy which was successfully applied in Sierra Pintada, with emphasis on the following points: (a) the need for adequate geological knowledge of the area; (b) the advantage of a massive survey (in this case, air survey); (c) the necessity for exploration (drilling) in order to define the anomalies and make their evaluation possible; and (d) the convenience of extending exploration

    Goldstone, J.A.

    1994-01-01

    High in the northcentral mountains of Los Alamos, New Mexico, is the Manuel Lujan Jr. Neutron Scattering Center (LANSCE), a pulsed-spallation neutron source located at Los Alamos National Laboratory. At LANSCE, neutrons are produced by spallation when a pulsed 800-MeV proton beam impinges on a tungsten target. The proton pulses are provided by a linear accelerator and an associated Proton Storage Ring (PSR), which alters the intensity, time structure, and repetition rate of the pulses. In October 1986, LANSCE was designated a national user facility, with a formal user program initiated in 1988. In July 1989, the LANSCE facility was dedicated as the Manuel Lujan Jr. Neutron Scattering Center in honor of the long-term Congressman from New Mexico. At present, the PSR operates with a proton pulse width of 0.27 μs at 20 Hz and 80 μA, attaining the highest peak neutron flux in the world and close to its goal of 100 μA, which would yield a peak thermal neutron flux of 10 16 n/cm -2 s -1 . This paper discusses the target/moderator/reflector shield system, the LANSCE instruments, the facility improvement projects, and user programs

    Presents an obituary for Herbert L. Pick Jr. For 49 years at the University of Minnesota's Institute of Child Development, new students were often greeted by an unassuming guy who rode to work on his bike, helped them carry boxes of books to their offices, and turned out to be a famous professor. Herbert L. Pick Jr. was a fabulous mentor, teacher, and developmental scientist. His work on perception and perceptual development spanned basic and applied science, laboratory and real-world settings. He was honored with the Division 7 (Developmental Psychology) Mentor Award from the American Psychological Association in 1998. He was honored again in 2002, jointly with his wife Anne D. Pick, with a volume of the Minnesota Symposium on Child Psychology based on a central theme of their work and titled "Action as an Organizer of Learning and Development." Two weeks before his death he was honored yet again with a Festschrift titled "Realism to Relevance: An Ecological Approach to Perception, Action and Cognition." Former students and academic admirers gave talks focused on the scientific themes Herb championed, namely, effects of experience on learning and development, organism-environment fit, environmental structure, and societal applications of research about basic psychological processes. He gave the final talk, and after thanking everyone in his typically humble way, he discussed his new research on visual-locomotor coordination. Herb died on June 18, 2012. He is greatly missed by Anne, his wife of 50 years; his sister Barbara; his daughters (and their husbands) Cindy (Jon), Karen (John), and Gretchen (Michael); and his grandchildren Alex, Ted, Katy, Joe, Eva, Sam, Rowan, and Culley. He is also missed by his many students, colleagues, friends, and admirers.

    As a part of the jet lift V/STOL research by National Aerospace Laboratory, a study of trial manufacture of ultra light weight jet engine JR 100 started in FY 1964. The study was aimed at obtaining a lift engine for VTOL and founding the base for the future jet lift VTOL, and at taking in the results of the jet engine element study accumulated so far and manufacturing an advanced engine. Decided on the use of domestic materials for JR 100, the materials to be used are almost iron-based ones. Through the efforts for weight reduction in structure and processing, a thrust/weight ratio of 10 was realized. At the same time, the production/processing of light weight materials such as titanium alloys was proceeded with, and by adopting the materials to JR 200 system, a thrust/weight ratio of 15 was realized. Together with these, for the purpose of reducing the fuel consumption rate, studies started on fan for lift fan engine and high temperature turbine (an inlet temperature of 1250 degrees C was achieved), to get low noise/high efficiency fan. By the research results, the basis for jet lift VTOL was established, and it became the basis for the development of turbo fan engine FJR 710. (NEDO)

    With the objective of to get to forecast and operative determinations tool to seeding of hailstorm in the damage mitigations job that produces its precipitation in Mendoza (Argentina), we developed to software based in on surface and 500 mb. level atmospherics variable. We had used on surface dates because in this level exist to big amount of information, practically it is possible to get its measures continuously; in addition it is the level that data of damages are registered that the hail precipitation produces. The decision to use the level of 500 mb, it must to that it is the height in which the upset one of the air circulation takes place from the Pacific to Mendoza, who produces important changes and instability in the atmosphere of Mendoza, these data were obtained from the radiosonde of Santo Domingo in Santiago (Chile) and El Plumerillo (Mendoza). In the program is integrated the different indices and models obtained in ours works from investigation on the subject of last the five years. Since the October of 2004 to April of 2009 the values have been taken from the variables mentioned every day, hourly during the fight campaigns antihail (October-April). The results have integrated in the program INCAS, whom it is due to enter the surface variables: Temperature in °C, the dew point in °C, the atmospheric pressure in mb., the index of ultraviolet solar radiation, the direction and wind speed; whereas the variables of the level of 500 are due to introduce mb: height of the level of 500 mb in meters, temperature of the level in °C, the direction and wind speed to that height. From the process of these variables the type of convective process is obtained like exit of the program , that is more probable that it appears in Mendoza for these atmospheric conditions; the thresholds that trigger to the stormy processes and their possible severity. This year software was validated in his first version, obtaining itself very good results.

    WALTER R. COURTENAY, JR., ichthyologist and retired professor, Florida Atlantic University, Boca Raton, Florida, died in Gainesville, Florida, on 30 January 2014 at age 80. Walt was born in Neenah, Wisconsin, on 6 November 1933, son of Walter and Emily Courtenay. Walt's interest in fish began at a young age as evidenced by a childhood diary in which at 13 years of age he wrote about his first catch—a two-and-a-half pound “pike” from Lake Winnebago. When Walt turned ten, the family moved from Wisconsin to Nashville, Tennessee, the move precipitated by his father accepting a position as pastor of the First Presbyterian Church. During those early days in Nashville, Walt's father would take summers off and travel to Michigan to teach at Camp Miniwanca along the shore of Lake Michigan where father and son honed their angling skills. It was also at that time Walt's father had definite views on what his son should be doing in adult life—in Walt's case it was to become a medical doctor. However, his Woods Hole internship in marine biology and oceanography toward the end of his undergraduate years was a transformative experience for him so much so that he abandoned all ideas of becoming a medical doctor and instead specialized in ichthyology and oceanography. Apart from the inherent interest and opportunities Woods Hole opened to him, being back at the shore of a large body of water, in this case the Atlantic Ocean, was far more interesting than sitting in lectures on organic chemistry. With that, Walt completed his B.A. degree at Vanderbilt University in 1956. In 1960 while in graduate school in Miami, Walt met and married Francine Saporito, and over the next several years had two children, Walter III and Catherine. He went on to receive his M.S. in 1961 from The Rosenstiel School of Marine and Atmospheric Science at the University of Miami on the systematics of the genus Haemulon (grunts) and his Ph.D. degree in 1965 working under his advisor C.

It explores in a preliminary and descriptive form some of the categories presented in the framework proposed for the specific case of Mendoza, Argentina. It identifies a double working dynamic in the hydrologic regime: one between the hydrologic authorities and large-scale and powerful stakeholders of the wine industry and another dynamic between a series of non-hydrologic satellite entities and small-scale producers. This leads to a hydrologic policy that reproduces a production model that clearly benefits one sector at the expense of another.

    2004-12-01

    Professor Leverett Davis Jr., Professor of theoretical physics at the California Institute of Technology, died on June 15, 2003 after a long illness. He was 89 years old. He contributed many important ideas and concepts to theoretical astrophysics and was a pioneer in the in situ scientific exploration of space using observations from spacecraft. Davis was born in Elgin, Illinois on March 3, 1914, the eldest of four children of Louis Leverett Davis and Susan Gulick Davis. His parents moved several times as he grew up because his father, a mining engineer, became involved in different mining operations in the American West. Leverett married Victoria Stocker in June 1943. They had two children who died in childhood and subsequently adopted a son, Jeffrey. His wife and son survive him. Davis's early education was rather fractured and uneven because of the many family moves, with periods of home schooling alternating with regular school. His high school education was, on the other hand, reasonably normal. It was while in high school that he decided that he wanted to do physics or mathematics. He went on to earn his Bachelor of Science degree at Oregon State College in 1936, after which he started graduate studies at the California Institute of Technology, to pursue a graduate degree in physics. His advisor was William V. Houston and Davis received his PhD in 1941 for a thesis on electrical properties in nerves. He briefly entertained the idea of changing to work in biophysics. During World War II, Davis became an integral member of the Caltech project for rockets, which developed a number of different types of rockets used in the war. As a result of this war work, Davis wrote a book on Exterior Ballistics, published by Van Nostrand in 1958. He joined the faculty at the California Institute of Technology in 1946, after several years on campus as an instructor. In all, he taught there for nearly four decades before retiring as Professor of Theoretical Physics in 1981

  4. Paleozoogeography of the Wine Mouse (Akodon oenos & Late Holocene Paleoenvironments in South-Central Mendoza, Argentina

    Directory of Open Access Journals (Sweden)

    Fernando Julián Fernández

    2011-02-01

    Full Text Available Cranial remains of the wine mouse (Akodon oenos are documented from an archaeological site in south-central Mendoza, Argentina (Agua de La Mula, 35º22' S, 68º15' W, which dates to the end of the late Holocene (1610 ± 60; 1260 ± 60; 1000 ± 50 C14 yr B.P.. The taxonomic status of this small rodent is currently being assessed, but these remains represent the first fossil record for the morphotaxon A. oenos. The species’ present distribution is restricted to a few records from Mendoza province. Analysis of the remains supports paleoenvironmental reconstruction using the small mammal assemblage recovered from this site. From the late Holocene into modernity temperature decreased and winter precipitation increased, resulting in advance of Patagonian steppe grading with altitude into Monte desert. Holocene climatic conditions may explain the relatively late human occupation of ecologically marginal environments in this region, which probably favored effective human occupation of the Payunia region at sites such as Agua de La Mula between 1600 and 1000 years B.P.

    Knowledge of the chemical composition of wine and its association with the grape variety/cultivar is of paramount importance in oenology and a necessary tool for marketing. Phenolic compounds are very important quality parameters of wines because of their impact on colour, taste and health properties. The aim of the present work was to study and describe the non-flavonoid and flavonoid composition of wines from the principal red grape varieties cultivated in Mendoza (Argentina). Sixty phenolic compounds, including phenolic acids/derivatives, stilbenes, anthocyanins, flavanols, flavonols and dihydroflavonols, were identified and quantified using high-performance liquid chromatography with diode array detection coupled with electrospray ionisation mass spectrometry (HPLC-DAD/ESI-MS). Marked quantitative differences could be seen in the phenolic profile among varieties, especially in stilbenes, acylated anthocyanins and other flavonoids. The polyphenolic content of Malbec wines was higher compared with the other red varieties. Dihydroflavonols represent a significant finding from the chemotaxonomic point of view, especially for Malbec variety. This is the first report on the individual phenolic composition of red wines from Mendoza (Argentina) and suggests that anthocyanins, flavanols and phenolic acids exert a great influence on cultivar-based differentiation.

  6. Water in the Mendoza, Argentina, food processing industry: water requirements and reuse potential of industrial effluents in agriculture

    Directory of Open Access Journals (Sweden)

    Alicia Elena Duek

    2016-04-01

    Full Text Available This paper estimates the volume of water used by the Mendoza food processing industry considering different water efficiency scenarios. The potential for using food processing industry effluents for irrigation is also assessed. The methodology relies upon information collected from interviews with qualified informants from different organizations and food-processing plants in Mendoza selected from a targeted sample. Scenarios were developed using local and international secondary information sources. The results show that food processing plants in Mendoza use 19.65 hm3 of water per year; efficient water management practices would make it possible to reduce water use by 64%, i.e., to 7.11 hm3. At present, 70% of the water is used by the fruit and vegetable processing industry, 16% by wineries, 8% by mineral water bottling plants, and the remaining 6% by olive oil, beer and soft drink plants. The volume of effluents from the food processing plants in Mendoza has been estimated at 16.27 hm3 per year. Despite the seasonal variations of these effluents, and the high sodium concentration and electrical conductivity of some of them, it is possible to use them for irrigation purposes. However, because of these variables and their environmental impact, land treatment is required.

    The strontium, carbon and oxygen isotopic signal of the past oceans is accurately recorded by authigenic marine minerals such as carbonates, sulfates and phosphates. The variation of these isotope ratios through the geological time is used as a tool in correlating and dating marine sedimentary rocks. Many works have been done concerning to the changes in carbon, oxygen and strontium isotope ratios of different marine successions in the world. These allow the construction of curves of secular variations of the isotope signals with geological time (Jones et al., 1994a, 1994b; Veizer et al., 1999; Jacobsen and Kaufman, 1999). This work presents strontium, carbon and oxygen isotope ratios of Early Jurassic biogenic marine carbonates of Cuenca Neuquina in southwestern Mendoza (au)

  12. The Medical Vocabulario terminológico of Manuel Hurtado de Mendoza

    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.

    Full Text Available Lately, several authors have been analyzing the changes in rural areas triggered by globalization. The concepts of new rurality and pluriactivity have allowed progress along these lines, highlighting the new difficulties facing the most vulnerable sectors. This study explores the transformation of peripheral rural territories in Mendoza (Argentina, particularly those that have been thought of as isolated and traditional. This research develops from a case study, combines quantitative and qualitative methods, and takes the production undertakings happening in those lands as units of analysis. Production and economic situations of the past are compared to those in the present. The tendency toward pluriactivity is here considered as a response to the new conditions, and also as an expression of the process of articulation with the capitalist system.

    Full Text Available La provincia de Mendoza posee una rica fauna de lagartos pertenecientes a las familias Leiosauridae, Liolaemidae, Teiidae, Scincidae y Gekkonidae. Algunos son propios del Monte, Puna, Payunia o región andina, mientras que otros poseen una amplia distribución, ocupando dos o más ecosistemas. El objetivo de este trabajo fue actualizar la lista lacertofaunística de la provincia y determinar las áreas de mayor riqueza de especies en relación a estos cuatro tipos de ecosistemas. Se utilizaron datos de procedencia de 43 especies de lagartos a partir de colecciones herpetológicas y de bibliografía. Las localidades fueron georreferenciadas y mapeadas. Una primera estimación de las áreas de mayor riqueza fue realizada sobre la base de las distribuciones de acuerdo a los puntos de colecta. En un segundo análisis, se generaron modelos predictivos de distribución utilizan-do 26 variables ambientales. Estas áreas potenciales fueron superpuestas a fin de obtener el número de especies en cuadrículas de 4,6 km x 4,6 km. Los resultados de ambos métodos indican que la mayor riqueza de especies se encuentra en la Payunia, probablemente en relación a la mayor heterogeneidad ambiental de la zona, ya que es considerada un área ecotonal entre la región fitogeográfica de la Patagonia y el Monte. Un análisis de similitud (Índice de Morisita demuestra que la similitud entre ecosistemas en cuanto a la composición de especies es baja, conformándose dos grupos: el Monte y Patagonia por un lado, y el ecosistema Andino y Puneño por otro.

    Full Text Available El propósito del presente trabajo es analizar los cambios y las continuidades en el proceso de formación del mercado de trabajo en la provincia de Mendoza a comienzos del siglo XX. La incorporación de un número significativo de inmigrantes a finales del siglo XIX junto a un proceso de reorganización productiva asociado al desarrollo de la industria vitivinícola, implicó cambios en las relaciones sociales y en las condiciones de vida de amplios sectores de la población mendocina. Iniciado el siglo XX, la vitivinicultura se convirtió en la principal actividad productiva de la provincia y la más importante en su rubro a nivel nacional. Los viñateros, productores agroindustriales, industriales bodegueros, contratistas de viñas , etc., fueron constituyéndose en parte de una sociedad cada vez más heterogénea y diversa, producto del desarrollo capitalista que experimentó la región desde el último tercio del siglo XIX y que se insertó en el proceso de incorporación de la economía Argentina al mercado mundial. Este período resulta de suma importancia porque se determinó un sistema productivo en torno a la actividad vitivinícola de la provincia que dio forma al mercado de trabajo regional. En este contexto, la inserción de los trabajadores se dio de una manera muy dispar en el proceso productivo, caracterizado por una alta estacionalidad y una escasa especialización de la mano de obra requerida.The aim of this work is to analyze the changes and continuities during the process of formation of the labor market in the province of Mendoza in the early 1900s.

    Full Text Available Se estudió la bionomía de Diaspidiotus perniciosus Comstock (“escama de San José”, en manzanos de la variedad “Red delicious” de San Carlos, Mendoza, Argentina, durante los ciclos productivos 2007-2008 y 2008-2009. Se determinó el número de generaciones anuales y se estudiaron las fluctuaciones poblacionales asociadas a la integral térmica para la especie en esta región. D. perniciosus presenta dos generaciones superpuestas al ciclo del cultivo, mientras que las ninfas (N1 y N2 de la tercera generación se desarrollan solamente hasta el final de la temporada estival y pasan al estado de quiescencia, en el que permanecen durante el invierno. El desarrollo de D. perniciosus en esta zona coincide con el de esta especie en la zona frutícola del centro de Chile en cuanto al número de generaciones y al periodo de quiescencia invernal. La población quiescente en Chile está integrada predominantemente por ninfas del primer estadio (N1, mientras que en San Carlos, Mendoza, la población quiescente está integrada principalmente por ninfas del segundo estadio (N2. La similitudes entre ambas poblaciones se deben, probablemente, a las coincidencias en latitud, clima y especie hospedera. El impacto económico de D. perniciosus en la zona de estudio tiene mayor relevancia durante los meses de diciembre y enero, cuando se observa una alta incidencia de daños en los frutos y las hojas; este es el momento decisivo para implementar medidas de control fitosanitario. Estas deberán aplicarse en función de los máximos poblacionales de N1 que se producen con 600-650 Grados-Día (oD en diciembre y con 1.170-1.270oD en enero. En las temporadas en las que la densidad poblacional de la plaga es especialmente alta, podrían incorporarse medidas adicionales de control con 1.800-2.000oD durante el mes de abril. Los resultados de estos estudios representan una herramienta predictiva, que permitirá elaborar estrategias para el control de poblaciones de

    1973-07-01

    Community involvement is not just one facet of the new Martin Luther King, Jr., General Hospital's existence. It is the mainstream from which all other activities flow. In addition to meeting the conventional needs of a conventional hospital staff with the core collection of texts and journals, this library goes one step further. It acts as a resource for its community health workers, dietitians, and nurses in their various outreach programs. It serves as a stimulus for the high school or community college student who may be curious about a health career. It also finds time to provide reading material for its patients.

  6. Solar radiation in forested urban environments with dry climate. Case: Metropolitan Area of Mendoza, Argentina

    Full Text Available The aim of this work is to advance the understanding of the solar potential of urban residential environments which, by their morphology, and the impact of urban trees, present values of irradiance very different from full solar collection. Morphological variables of urban settings and urban trees, a very distinctive feature of the Mendoza Metropolitan Area (MMA, have a fundamental impact on the feasibility of implementing strategies for solar energy utilization in urban environments. The results achieved will contribute to modify and gradually update urban and building legislation to implement higher levels of energy efficiency and minimum environmental impacts.This work proposes to study the potential of solar collection in urban environments, analyzing eleven urban configurations selected according to their building and urban morphological characteristics.Methodologically, we have monitored the global solar irradiance on vertical plane on northern facades, completely sunny and partly sunny, affected by solid masking and arboreal masking. Results obtained so far indicate that solar masking is critical for vertical surfaces, with a reduction of the available solar energy between 2% and 66% in the winter season. However, these drawbacks caused by urban trees are compensated by benefits in the warm season: controlling the intensity of the urban heat island, absorption of pollutants, cooling and humidifying the air through evapotranspiration, reducing thermal loads of buildings, occupancy of public open spaces, and an invaluable contribution to the urban aesthetic.

    Full Text Available Este trabajo propone trazar un panorama general del desarrollo de la Arquitectura Moderna en Mendoza entre 1930 y 1970, a través de los autores y obras más significativos. La producción arquitectónica lograda en el período, en el presente de valor patrimonial, no cuenta con acciones gubernamentales ni legislación de protección. Esto se debe a dos razones concurrentes: La primera, desde el imaginario social el recorte temporal de lo patrimonial finaliza con la arquitectura de los años ’20 del siglo pasado. La segunda razón, la estética y la vigencia funcional de estas obras impiden poner la distancia crítica que requiere toda mirada histórica, aún más desde lo cultural. Vamos a revisar algunos autores a partir de sus trayectorias y su producción arquitectónica, con el objetivo de descubrir las singularidades de la producción local, haciendo aportes para la valoración de estos bienes y por ende para su patrimonialización.

    Satellite image such as Landsat 5 TM scene provides excellent representation of Earth and synoptic view of large geographic areas in different band combination. Landsat TM images allow automatic and semi-automatic classification of land cover, nevertheless the software frequently may some difficulties in distinguishing between similar radiometric surfaces. In this case, the use of Digital Elevation Model (DEM) can be an important tool to identify different surface covers. In this study, several False Color Composite (FCC) of Landsat 5 TM Image, DEM and the respective draped image of them, were used to delineate lithological boundaries and tectonic features of regional significance of the Paven Volcanic Field (PVF). PFV is a Quaternary fissural structure belonging to the black-arc extensional areas of the Andes in the Mendoza Province (Argentina) characterized by many composite basaltic lava flow fields. The necessity to identify different lava flows with the same composition, and then with same spectral features, allows to highlight the improvement of synergic use of TM images and shaded DEM in the visual interpretation. Information obtained from Satellite data and DEM have been compared with previous geological maps and transferred into a topographical base map. Based on these data a new lithological map at 1:100.000 scale has been presented [it

    Full Text Available Due to its geographical location, the community of Motozintla de Mendoza (Motozintla in the State of Chiapas, Mexico, is continuously exposed to the impact of natural hazards. In this work, we assessed the flood risk of Motozintla considering the structural, socioeconomic, organizational, and global (structural, socioeconomic, and organizational vulnerabilities. In addition, we also measured the local risk perception. Spatial maps were generated to determine the most vulnerable and risk areas of this community. Our results indicate that the population has a high level of risk to flooding mainly because (1 the majority of the local houses has high structural vulnerability; (2 a high percentage of the families has a daily income less than the official Mexican minimum wage and lacks of basic public services as well as of proper social security services; (3 most of the community does not know any existing Civil Protection Plan; and (4 the community organization for disaster mitigation and response is practically non-existent. For these reasons, we believe that it is necessary for local authorities to establish in the short-term, preparedness, mitigation and response plans as well as land-use measures to reduce the risk to floods in Motozintla.

    1998-01-01

    The metamorphic rocks of the Cordillera Frontal exposed in the Cordon del Portillo, Mendoza were examined by Rb/Sr geochronology and Nd/Sm isotopic analysis. The Rb/Sr data defined a Devonian age for the last metamorphic episode, similar to the previous K/Ar and Ar/Ar ages obtained in this region and western Precordillera. The isotopic analysis identified three sets of model ages: 1.- The oldest corresponds to a set of meta sedimentary rocks with a model age of 1,400 to 1,700 Ma; 2.- A monzogranodiorite with a model age of 1,000 Ma; and 3.- Metabasites with model ages between 577 and 330 Ma. These rocks are interpreted as 1.- A typical Grenvillian derived basement; 2.- Late Paleozoic granitoids derived from a different Proterozoic basement; and 3.- Some Eopaleozoic metabasites tectonically inter fingered with the Grenvillian basement. These new data are coherent with the existence of a Laurentia derived terrane, Chilenia, that was separated by oceanic rocks from the basement of Pre cordillera during Eopaleozoic times. This last basement known as the Cuyania terrane, was also derived from Laurentia. (author)

    Full Text Available For a century, Citizens & Southern Bank was a fixture in Georgia. In 1991, the C&S brand name disappeared in a merger with North Carolina National Bank. This was one of the bittersweet consequences of the slow, confusing swirl of bank deregulation after 1970, when institutions such as C&S simply disappeared, swallowed by the “winners” in the new competitive environment of interstate banking in the 1980s and 1990s. Even earlier, however, the Lane family had ceased to control the bank started by Mills Lane, Sr. in 1891. Mills B. Lane, Jr. was the last member of the Lane family to run C&S. After his retirement in 1973, Mills handpicked his successor and tried to retain some influence, but the bank began slipping away from the Lanes. By the early 80s, a decade before Hugh McColl’s NCNB acquired C&S, Mills Lane, Jr. was deeply alienated from the institution that had been, according to many, “Georgia’s cornerstone bank.”

    Hip-Hop to Health Jr. was a diet/physical activity intervention designed to reduce gains in BMI (kilograms per meter squared) in preschool minority children. Twelve predominantly Latino Head Start centers participated in a group-randomized trial conducted between Fall 2001 and Winter 2003. Six centers were randomized to a culturally proficient 14-week (three times weekly) diet/physical activity intervention. Parents participated by completing weekly homework assignments. The children in the other six centers received a general health intervention that did not address either diet or physical activity. The primary outcome was change in BMI, and secondary outcomes were changes in dietary intake and physical activity. Measures were collected at baseline, post-intervention, and at Years 1 and 2 follow-up. There were no significant differences between intervention and control schools in either primary or secondary outcomes at post-intervention, Year 1, or Year 2 follow-ups. When Hip-Hop to Health Jr. was conducted in predominantly black Head Start centers, it was effective in reducing subsequent increases in BMI in preschool children. In contrast, when the program was conducted in Latino centers, it was not effective. Although the intervention did not prevent excessive weight gain in Latino children, it was very well received. Future interventions with this population may require further cultural tailoring and a more robust parent intervention.

    Full Text Available A comparative study of elements deposited on tree bark was carried out for urban and periurban areas of two of the most important cities in Argentina. The content of Fe, Mg, Al, Mn, Zn, Pb, Ba, Cr, Hg, Cu, Ni, Cd and Sb was determined by inductively coupled plasma atomic emission spectrometry (ICP-OES in Morus alba tree bark collected in the cities of Buenos Aires and Mendoza. The main air pollutants detected in the Buenos Aires urban area were Ba, Cr, Cu and Ni and indicate significative difference from the Mendoza urban and periurban areas. Significantly, higher concentrations of Zn, Ba, Cr and Cu were recorded in the periurban area of the city of Buenos Aires than in Mendoza. Bark samples were strongly influenced by dust and show Al, Fe, Mg and other element accumulations that indicate that soil particles were carried out by wind. Elements like Ba and Zn, commonly linked to traffic emissions, showed the highest concentrations in the Buenos Aires metropolitan area, possibly due to more intensive vehicular traffic. Our results indicated that intensity of vehicular traffic and not city structure is responsible for air pollution.Um estudo comparativo dos elementos depositados nas cascas das árvores foi realizado nas áreas urbanas e na periferia de duas cidades das mais importantes da Argentina.

    2015-08-01

    Full Text Available In this essay I reassess the complexity of the convergence between electronic music and media practices in Rome in the 1950s and 1960s, through the reconstruction of the experience of composer Gino Marinuzzi Jr (1920-96. His engagement with technology as a structuring device of compositional processes is fundamental and inescapable, and brings to the fore crucial issues of ‘applied’ music’s troublesome reputation in the Italian cultural discourse. In reviewing Marinuzzi’s biography over the period 1949-75, my goal is to exemplify the key phases of this transitional period in Italian music history, in which technology, through the spreading of media and their increasing importance in cultural representations, came to constitute a new value of musical activity and at the same time renewed old questions concerning music’s aesthetic autonomy.

  20. Permo-triassic volcanism in the San Rafael Block (Mendoza province) and its uraniferous potential

    International Nuclear Information System (INIS)

    Kleiman, L.E.

    1993-01-01

    This paper describes the Permo-triassic volcanism in the San Rafael Block, Mendoza, Argentina, which forms part of the Choiyoi province and it represents by large volumes of intermediate to silicic ignimbrites with minor sub volcanic bodies of rhyolites, andesites and basandesites. Three different suites can be distinguished: the first one (Lower Section) of Early Permian age, is composed of dacites and rhyolites (SiO 2 up to 71 %) with minor andesites, the second one (Upper Section) of Late Permian-Early Triassic age is made up of rhyolites (SiO 2 up to 77 %) with some basandesites and andesites, and the third one, of Triassic age is composed of rhyolites (SiO 2 > 75 %) and basandecites. These suites are easily distinguished by means of trace element data and are believed to represent the transition between a subduction-related magmatic arc and an extensional tectonic regime. This tectonic setting is similar to the prevalent during the Cenozoic in the Sierra Occidental of Mexico and is favourable for the development of long-lived hydrothermal systems which lead to economic U concentrations (i.e. Sierra de Pena Blanca). In the San Rafael Block, the Dr. Baulies-Los Reyunos U deposit, which is hosted in volcanic sediments, is associated to the first suite (Lower Section). Although minor U concentrations are known, up to date, to be related to the second and third suites, these rocks are fertile and seen to be potential source for the formation of uranium deposits within a volcanic caldera environment.

    The Plio-Pleistocene Llancanelo volcanic field is located in the south-eastern region of the province of Mendoza, Argentina. This wide back-arc lava plateau, with hundreds of monogenetic pyroclastic cones, covers a large area behind the active Andean volcanic arc. Here we focus on the northern Llancanelo volcanic field, particularly in Las Bombas volcano. Las Bombas volcano is an eroded, but still recognizable, scoria cone located in a circular depression surrounded by a basaltic lava flow, suggesting that Las Bombas volcano was there when the lava flow field formed and, therefore, the lava flow engulfed it completely. While this explanation seems reasonable, the common presence of similar landforms in this part of the field justifies the need to establish correctly the stratigraphic relationship between lava flow fields and these circular depressions. The main purpose of this research is to investigate Las Bombas volcano 3D subsurface architecture by means of geophysical methods. We carried out a paleomagnetic study and detailed topographic, magnetic and gravimetric land surveys. Magnetic anomalies of normal and reverse polarity and paleomagnetic results point to the occurrence of two different volcanic episodes. A circular low Bouguer anomaly was detected beneath Las Bombas scoria cone indicating the existence of a mass deficit. A 3D forward gravity model was constructed, which suggests that the mass deficit would be related to the presence of fracture zones below Las Bombas volcano cone, due to sudden degassing of younger magma beneath it, or to a single phreatomagmatic explosion. Our results provide new and detailed information about Las Bombas volcano subsurface architecture.

    Full Text Available RESUMEN: Alfonso Hojeda fue un notable canonista sevillano que en 1576 publicó en Venecia un libro acerca de los beneficios eclesiásticos. La obra se divide en dos partes: la primera está dedicada a argumentar en contra de la pluralidad de beneficios en una misma persona, de acuerdo con los decretos tridentinos de reforma, mientras la segunda trata en cambio de la compatibilidad de beneficios mediante dispensa papal. Los propios términos en que se manifiestan las dos partes ya están indicando las contradicciones en que ha de moverse el autor, difíciles de salvar. La doctrina de la causa es, además de la distinción entre órdenes normativos, la principal herramienta conciliatoria para Hojeda. El papa está desligado del derecho positivo o humano, pues de otro modo no podría dispensar, o privilegiar, mas sólo puede hacerlo con justa causa.ABSTRACT: Alfonso Hojeda de Mendoza was an outstanding canonist that in 1576 published a book in Venice on the eclesiástica benefits. The book is divided into two parts: the first one is devoted to argue against the plurality of benefits in the same person, according to Trento's decrees, while the second one deals, however, with the compatibility of benefits by the Pope's dispense. The own terms in which both parts are expressed reveal the contradictions, in which the author must move, always difficult to avoid. The doctrine of the cause, as well as the distinction among normative orders, is the main conciliatory tool for Hojeda. The Pope is unlinked to human or positive right, otherwise he could not dispense or privilege, however he can only do it for a just cause.

    Jr(a) is a high-prevalence red cell (RBC) antigen. The clinical significance of anti-Jr(a) is controversial. When hemolytic disease of the fetus and newborn (HDFN) occurred, most reported cases were clinically mild. We report the first case of fatal HDFN due to anti-Jr(a). A 28-year-old Caucasian woman with transfusion history was monitored at the 29th week of pregnancy (G4P1). An ultrasound scan showed fetal cardiomegaly and hepatomegaly. An antibody directed against a high-prevalence antigen was detected, but without conclusive identification. An emergency cesarean section was performed at the 36th week. The newborn was hydropic and showed severe anemia. Death occurred 30 hours after birth. Serologic methods were performed to investigate the mother's RBCs and serum. An in vitro functional cellular assay and semiquantitative measurement of anti-Jr(a) were used to determine the clinical significance of the antibody. Anti-Jr(a) was identified in the serum and Jr(a-) phenotype was confirmed. The anti-Jr(a) titer was 1024, with predominant immunoglobulin (Ig)G1 and minor IgG4 subclasses. The functional cellular assay was consistent with an antibody unlikely to cause HDFN. Semiquantitative measurement of anti-Jr(a) showed a reactivity equivalent to a 25 IU per mL (5 microg/mL) concentration of anti-D, a value associated with a significant risk of HDFN. This is the first documented case of fatal HDFN due to anti-Jr(a). Therefore, we recommend close monitoring of pregnant women with a high-titer anti-Jr(a), especially those with an incompatible transfusion history and/or multiple pregnancies. This case report provides new arguments about the clinical significance of anti-Jr(a) in the transfusion setting.

    Mansilla, M.; Dieguez, S.

    2014-01-01

    The Sierra Pintada uranium district in Mendoza Province, Argentina, was discovered by airborne survey. This deposit is associated with a volcanic caldera and occurs in the Lower Permian volcaniclastic sediments of the Cochico Group, in which aeolian and fluvial sandstones, inter-bedded with ignimbrites, were reworked by pyroclastic flows. The origin of the mineralization is interpreted as a product of the leaching of the inter-bedded rhyolitic tuff. The mineralization is lenticular and nearly concordant with the bedding. The deposit has been affected by a complex fault system, which is responsible for mineralization and disposition via spatial displacement. The primary uranium minerals are uraninite, brannerite and coffinite. Uranophane and low liebigite uranium are the products of the oxidative alteration of primary minerals. This study involves the technical and economical evaluation of the open pit uranium mining project Tigre I – La Terraza in Mendoza, Argentina, at prefeasibility level. Its development includes geological modeling through economic evaluation, and the incorporation of different mining-specific software.

    The origin of the International Center for Earth Sciences (ICES) dates back to 2002 when the Acoustic Emission Station on Volcano Peteroa was installed. Up to now, it represents the first of its kind in the entire Andean Cordillera. This scientific activity is jointly coordinated by scientists from Italy and Argentina. At the First Conference on Acoustic Emission held on 2004, a letter of intent for the establishment of ICES was signed. Presently, ICES is composed by 4 departments: Environment and Climate; Anthropology; Environmental and Territorial Environmental Risk; Resources and Exploration Geophysics. One of the primary objectives of ICES is to promoting applied research and development in the broad field of Earth Sciences. The experimental work consists of main 4 steps listed below: The 'Helianthus annus' (sunflower) has proven its ability to raise Uranium (U) in hydroponic systems and was widely used in the model U rizophyiltration extraction of groundwater in Ashtabula, Ohio, USA. Hydroponic trial design consists of 6 treatments and 4 repetitions plants witnesses without minimum level of U, U witnesses plants without and 4 with various levels of U (Stage 1). The Glomus intraradices is a mycorrhizal fungus used in strategies of U phyto-stabilization. Test consists in the cultivation of sunflower with roots inoculated with Glomus intraradices to determine their uptake and translocation of U (Stage 2). The inoculation of 'Glomus intraradices' in 'Helianthus annus' produces an effective symbiosis with the type of strain and its genetic diversity, some genotypes are highly suitable for this. There have been experiences of this kind in the basic research in several countries. In this work, we use the system in 'Helianthus-Glomus' phyto-stabilization or rizophyiltration soil as a strategy for bioremediation of U at the Malargue area, Province of Mendoza (Stage 3). It will launch a pilot test of the transfer plan, which involves creating a garden for the growth of

    Full Text Available Information regarding the echinoids in this dataset is based on the Agassiz Trawl (AGT and epibenthic sledge (EBS samples collected during the British Antarctic Survey cruise JR275 on the RRS James Clark Ross in the austral summer 2012. A total of 56 (1 at the South Orkneys and 55 in the Eastern Weddell Sea Agassiz Trawl and 18 (2 at the South Orkneys and 16 in the Eastern Weddell Sea epibenthic sledge deployments were performed at depths ranging from ~280 to ~2060 m. This presents a unique collection for the Antarctic benthic biodiversity assessment of an important group of benthic invertebrates. In total 487 specimens belonging to six families, 15 genera, and 22 morphospecies were collected. The species richness per station varied between one and six. Total species richness represents 27% of the 82 echinoid species ever recorded in the Southern Ocean (David et al. 2005b, Pierrat et al. 2012, Saucède et al. 2014. The Cidaridae (sub-family Ctenocidarinae and Schizasteridae are the two most speciose families in the dataset. They comprise seven and nine species respectively. This is illustrative of the overall pattern of echinoid diversity in the Southern Ocean where 65% of Antarctic species belong to the families Schizasteridae and Cidaridae (Pierrat et al. 2012.

Se determinó el número de generaciones anuales y se estudiaron las fluctuaciones poblacionales asociadas a la integral térmica para la especie en esta región. D. perniciosus presenta dos generaciones superpuestas al ciclo del cultivo, mientras que las ninfas (N1 y N2 de la tercera generación se desarrollan solamente hasta el final de la temporada estival y pasan al estado de quiescencia, en el que permanecen durante el invierno. El desarrollo de D. perniciosus en esta zona coincide con el de esta especie en la zona frutícola del centro de Chile en cuanto al número de generaciones y al periodo de quiescencia invernal. La población quiescente en Chile está integrada predominantemente por ninfas del primer estadio (N1, mientras que en San Carlos, Mendoza, la población quiescente está integrada principalmente por ninfas del segundo estadio (N2. La similitudes entre ambas poblaciones se deben, probablemente, a las coincidencias en latitud, clima y especie hospedera. El impacto económico de D. perniciosus en la zona de estudio tiene mayor relevancia durante los meses de diciembre y enero, cuando se observa una alta incidencia de daños en los frutos y las hojas; este es el momento decisivo para implementar medidas de control fitosanitario.

    Lynn White Jr.'s "The Historical Roots of Our Ecologic Crisis," which was published in Science in 1967, has played a critical role in precipitating interdisciplinary environmental studies. Although White advances a multifaceted argument, most respondents focus on his claim that the Judeo-Christian tradition, especially Christianity, has promoted anthropocentric attitudes and environmentally destructive behaviors. Decades later, some scholars argue contrarily that Christianity in particular and the world's predominant religions in general are becoming more environmentally friendly, known as the greening-of-religion hypothesis. To test these claims, we conducted a comprehensive review of over 700 articles-historical, qualitative, and quantitative-that are pertinent to them. Although definitive conclusions are difficult, we identified many themes and dynamics that hinder environmental understanding and mobilization, including conservative theological orientations and beliefs about the role of divine agency in preventing or promoting natural events, whether the religion is an Abrahamic tradition or originated in Asia. On balance, we found the thrust of White's thesis is supported, whereas the greening-of-religion hypothesis is not. We also found that indigenous traditions often foster proenvironmental perceptions. This finding suggests that indigenous traditions may be more likely to be proenvironmental than other religious systems and that some nature-based cosmologies and value systems function similarly. Although we conclude White's thesis and subsequent claims are largely born out, additional research is needed to better understand under what circumstances and communication strategies religious or other individuals and groups may be more effectively mobilized to respond to contemporary environmental challenges. © 2016 Society for Conservation Biology.

    Dr. Edward W. Burke Jr. passed away on June 15, 2011, after suffering a heart attack. Dr. Burke devoted his professional life to the research and teaching of physics and astronomy at King College in Bristol, Tennessee. Edward W. Burke, Jr., was born in Macon, Georgia, on September 16, 1924. He was a Navy veteran, having been commissioned as an ensign in 1944. He served in the Pacific near the end of World War II. He proceeded to complete his undergraduate degree in mathematics from Presbyterian College in 1947 and pursued the M.S. and Ph.D. in physics (1949 and 1954, respectively) at the University of Wisconsin. Under the direction of Professor Julian Mack, his thesis was titled "Isotope Shift in the Spectra of Boron." Although he did research in atomic spectra in the early part of his career, his interest in astronomy and variable stars in particular were his primary interests during his long academic career. Dr. Burke began his illustrious career at King College in 1949. He initiated the astronomy program there in 1950, included constructing a 12.5 inch Newtonian telescope, homemade as was most everything in those days. Many of his students learned about photometry at the Burke Observatory on the college campus. Burke was known for his trips to the Kitt Peak and Lowell observatories accompanied by undergraduate students on his trips, all of which were made by automobile which he preferred over flying. His initial interest in Ap stars later broadened into variable and especially eclipsing binary stars. His motivation was maintained by his desire to have his students experience basic research and to spark their interest in advanced degrees. Numerous students achieved advanced science and medical degrees because of Burke's encouragement and mentoring. In 1959, Dr. Burke was awarded a Fulbright professorship and traveled to Chile where he taught physics for a year in the Engineering School at the University of Chile in Santiago. He worked to establish a physics

    Raymond E. White, Jr., died unexpectedly at his home, in the early morning hours of October 12, 2004. Death appears to have been caused by severe diabetic shock. He retired from the Department of Astronomy/Steward Observatory in July 1999 with the title of University Distinguished Professor, after serving on the faculty of this institution for over 35 years. He was born in Freeport, Illinois, on 6 May 1933, to Beatrice and Raymond E, Sr. -the latter being a career soldier in the US Army. Ray's early schooling took place in Illinois, New Jersey, Germany and Switzerland, following his father's assignments. He obtained a bachelors degree from the University of Illinois in 1955. Next Ray enlisted in the US Army, but quickly was enrolled in Officer Candidate School. He then served as lst Lt. in the US Army Corps of Engineers. Although military affairs remained a lifelong interest, and he was a member of the Company of Military Historians, Ray decided after three years to return to academia. He entered the astronomy PhD program at the University of Illinois in 1958. His PhD dissertation was supervised by Ivan R. King. Ray accepted a faculty position at the University of Arizona in 1964. First and foremost, Ray White was known at Arizona as an excellent teacher, revered by a large number of former students. When the astronomy major program was begun in 1967, Ray was one of three, original, major advisors. Over the next three decades, he was a leader at the University level in reforming the undergraduate program and courses. He was selected Outstanding University Faculty Member in April 1989 and he served as one of a handful of professors who are Faculty Fellows. These Fellows devote untold hundreds of hours as part-time residents at student dormitories, to give students a friendly face to address their problems. In 1995, Ray was among the first group of faculty to be recognized as University Distinguished Professors. In the year of his retirement, 1999, University

These practices are based on technologies that operate articulating power relations of these actors in connection to world agro-foods markets. The article has an interpretive emphasis and is based on analysis of information generated from in-depth interviews to businessmen of the wine, canning, oil and livestock industries with international commercial links and located in the oasis of the Mendoza river in Argentina. Throughout the paper we analyze certain "techno-ecological practices" and how they are embedded into a specific device that locates and differentiates these entrepreneurs not only in international markets, but also before State and society.

    Facial / microfacial studies and geochemical isotopic analyses on marine jurassic carbonates of the Calabozo Formation (Dessanti, 1973) were carried out to reconstruct the palaeoenvironment and postdepositional history of the unit. This study is part of a project which purpose is the sedimentological and geochemical characterization of the Jurassic carbonate sequences of Cuenca Neuquina, in the southwestern Mendoza, Argentina. A detailed description about this basin can be found in Legarreta and Uliana (1999) and Riccardi et al. (2000). During the Late Bathonian and Early Callovian, the basin showed a reduction of the sedimentation area and a marked marginal facies progradation. West of Malargue, in areas with low detritic contribution, limestones of the Calabozo Formation were deposited. At the end of the Early Callovian, the basin was isolated, prevailing hypersaline conditions which caused the accumulation of the evaporites of the Tabanos Formation (Stipanicic, 1966) (au)

    The aim of this work is to obtain an index for predicting the probability of occurrence of zonda event at surface level from sounding data at Mendoza city, Argentine. To accomplish this goal, surface zonda wind events were previously found with an objective classification method (OCM) only considering the surface station values. Once obtained the dates and the onset time of each event, the prior closest sounding for each event was taken to realize a principal component analysis (PCA) that is used to identify the leading patterns of the vertical structure of the atmosphere previously to a zonda wind event. These components were used to construct the index model. For the PCA an entry matrix of temperature ( T) and dew point temperature (Td) anomalies for the standard levels between 850 and 300 hPa was build. The analysis yielded six significant components with a 94 % of the variance explained and the leading patterns of favorable weather conditions for the development of the phenomenon were obtained. A zonda/non-zonda indicator c can be estimated by a logistic multiple regressions depending on the PCA component loadings, determining a zonda probability index \\widehat{c} calculable from T and Td profiles and it depends on the climatological features of the region. The index showed 74.7 % efficiency. The same analysis was performed by adding surface values of T and Td from Mendoza Aero station increasing the index efficiency to 87.8 %. The results revealed four significantly correlated PCs with a major improvement in differentiating zonda cases and a reducing of the uncertainty interval.

  5. Alkaline lavas from southern Mendoza, Argentina, extend the Patagonian DUPAL mantle field to the north

    The lavas sampled around Río Colorado ~37°S at the border of Mendoza and Neuquén provinces, Argentina, define an OIB-like end-member composition for the Pleistocene and Holocene activity in the Payún Matrú volcanic field. Although positioned in the far back-arc of the Andes, only a few lavas show signs of involvement of slab fluids or crustal contamination such as relatively high LILEs relative to Nb. The very low La/Nb (~0.66) and Zr/Nb (~5) and high U/Pb (0.3-0.4) of the end-member composition clearly distinguish the source from normal MORB mantle, while high Ba/Nb (~10) and K/Nb (370-400) compared to FOZO and HIMU type OIBs suggest an EM type of mantle. Overall, the trace element patterns of the Río Colorado lavas are similar to the central and north Patagonian intraplate basalts and to South Atlantic E-MORB affected by the Discovery plume and the LOMU component (le Roux et al., 2002, EPSL 203). The isotopic composition of the Río Colorado component has a 206Pb/204Pb = 18.4, 207Pb/204Pb = 15.58, 208Pb/204Pb = 38.3, 87Sr/86Sr = 0.70353 and 143Nd/144Nd = 0.51285. This composition overlaps the central and north Patagonian intraplate basalts in Pb-isotopic space but is slightly less enriched in Sr and Nd-isotopes. It is distinctly different from the FOZO like composition of the south Patagonian intraplate basalts and the nearby Juan Fernandéz plume but similar to the South Atlantic N-MORB and MORB from the southern Chile Ridge segment 4 (Sturm et al., 1999, JGR 104) described as DUPAL type. The DUPAL-MORB type isotopic composition and the plume-like trace element patterns of the Río Colorado lavas suggest the presence of a weak plume beneath the area. The eruption of the large Payún Matrú volcano and the gigantic Pleistocene flood basalts also calls for a thermal anomaly to produce these melts during a weakly compressive tectonic regime with no significant addition of slab fluids.

    Jr(a) is a high-prevalence antigen. The rare Jr(a-) individuals can form anti-Jr(a) after exposure to the Jr(a) antigen through transfusion or pregnancy. The clinical significance of anti-Jr(a) is not well established. This study reports a case of a 31-year-old woman with a previously identified anti-Jr(a) who required massive transfusion of RBCs after developing life-threatening postpartum disseminated intravascular coagulopathy. Despite the emergent transfusion of 15 units of Jr(a) untested RBCs, she did not develop laboratory or clinical evidence of acute hemolysis. The patient's anti-Jr(a) had a pretransfusion titer of 4 and a monocyte monolayer assay (MMA) reactivity of 68.5% (reactivity > 5% is considered capable of shortening the survival of incompatible RBCs). The titer increased fourfold to 64 and the MMA reactivity was 72.5% on Day 10 posttransfusion. Review of laboratory data showed evidence of a mild delayed hemolytic transfusion reaction by Day 10 posttransfusion. Despite rare reports of hemolytic transfusion reactions due to anti-Jr(a) in the literature, most cases, including this one, report that this antibody is clinically insignificant or causes only mild delayed hemolysis. Clinicians should be advised to balance the risks of withholding transfusion with the small chance of significant hemolysis after transfusion of Jr(a+) RBCs in the presence of anti-Jr(a).

    Introduction The preschool years provide a unique window of opportunity to intervene on obesity-related lifestyle risk factors during the formative years of a child’s life. The purpose of this study was to assess the impact of a preschool-based obesity prevention effectiveness trial at 1-year follow-up. Design RCT. Settings/participants Primarily African American children (aged 3–5 years, N=618) attending Head Start preschool programs administered by Chicago Public Schools. Methods Eighteen preschools were randomly assigned in 2007–2008 to receive either: (1) a 14-week teacher-delivered intervention focused on healthy lifestyle behaviors; or (2) a 14-week teacher-delivered general health curriculum (control group). Main outcome measures The primary outcome, BMI, was measured at baseline, post-intervention, and 1-year follow-up. Diet and screen time behaviors were also assessed at these time points. Multilevel mixed effects models were used to test for between-group differences. Data were analyzed in 2014. Results Significant between-group differences were observed in diet, but not in BMI z-score or screen time at 1-year follow-up. Diet differences favored the intervention arm over controls in overall diet quality (p=0.02) and in subcomponents of diet quality, as measured by the Healthy Eating Index-2005, and in fruit intake (servings/day, excludes juice) (p=0.02). Diet quality worsened more among controls than the intervention group at 1-year follow-up. Conclusions The adaptation of Hip-Hop to Health Jr. produced modest benefits in diet quality, but did not significantly impact weight gain trajectory. Not unlike other effectiveness trials, this real-world version delivered by Head Start teachers produced fewer benefits than the more rigorous efficacy trial. It is important to understand and build upon the lessons learned from these types of trials so that we can design, implement, and disseminate successful evidence-based programs more widely and effectively

He had a short but active career as a research astronomer at Perkins Observatory at Ohio Wesleyan University in Delaware, Ohio before World War II, in which he served as an officer in the Army Air Force. After the war ended he turned to full-time teaching and administration at the University of Akron, and then at Hood College in Frederick, Maryland. Ernest was born on 10 September 1909 in Westerville, Ohio, where his father, Ernest H. Cherrington, Sr., was a leader in the temperance movement and publisher of "American Issue", a Prohibitionist magazine. Ernest Jr.'s mother, Betty Clifford (née Denny) Cherrington, was a homemaker. He was an outstanding student in high school and at Ohio Wesleyan University, which he entered in 1927. The little university's Perkins Observatory with its 69-inch reflector, briefly the second largest telescope in the United States, had just been built and gone into operation. After graduating with a BA magna cum laude in astronomy in 1931, Ernest stayed on one more year and earned his MS with a thesis on the motion of material in the tail of Comet Morehouse, supervised by Nicholas T. Bobrovnikoff. In 1932 Ernest entered the University of California at Berkeley as a graduate student, with a one-year teaching assistantship in the Astronomical Department. This was followed by a two-year Lick Observatory Fellowship. In June 1933 he married Ann McAfee Naylor, who had been a classmate at Delaware High School and Ohio Wesleyan. Ernest did his PhD thesis on spectrophotometry of the Mg I b lines in the solar spectrum, using a high-resolution grating spectrograph on the Berkeley campus, designed by C. Donald Shane, his adviser. In this thesis, Ernest tested and improved the then current theory of strong absorption lines in stellar atmospheres. He also spent several short periods at Lick Observatory on Mount Hamilton

For the evaluation of the bio-energetic potential, derived from the biomass, the WISDOM methodology developed by FAO and implemented by INTA in Argentina was applied with the collaboration of national and provincial governmental entities that contribute local information The study of the potential production and the development of the bio-energetic crops have been carried out with the advising and participation of the experts of INTA of the studied crops. The province of Mendoza has semi-deserted agro-climatic characteristics. The type of soil and type of weather allows the production of great quality fruits and vegetables in the irrigated areas. The four great currents of water conform three oasis; Northeast, Center and South, which occupy the 3.67% of the surface of Mendoza. Today, Mendoza has 267,889 irrigated hectares, but the surface that was farmed by irrigation was near to the 400,000 ha. The climate contingencies, froze and hailstorm precipitations, plus the price instability cause great losses in the productive sector, taking it to the forlornness of the exploitations. The crop setting of these forlornness lands with crops directed to the production of bio-fuels and the utilization of the biomass coming from the agriculture activities and the agro industry (pruning of fruit trees, refuses of olive and vine, remnants of the peach industry, etc.) could assist the access to the energy in the rural areas, stimulating the economical improvement and the development in these communities.

  13. Elastic-plastic fracture assessment using a J-R curve by direct method

    1996-01-01

    In the elastic-plastic evaluation methods, based on J integral and tearing modulus procedures, an essential input is the material fracture resistance (J-R) curve. In order to simplify J-R determination direct, a method from load-load point displacement records of the single specimen tests may be employed. This procedure has advantages such as avoiding accuracy problems of the crack growth measuring devices and reducing testing time. This paper presents a structural integrity assessment approach, for ductile fracture, using the J-R obtained by a direct method from small single specimen fracture tests. The J-R direct method was carried out by means of a developed computational program based on theoretical elastic-plastic expressions. A comparative evaluation between the direct method J resistance curves and those obtained by the standard testing methodology on typical pressure vessel steels has been made. The J-R curves estimated from the direct method give an acceptable agreement with the approach proposed in this study which is reliable to use for engineering determinations. (orig.)

    Willson, Lee Anne; Struck, Curtis

    2011-12-01

    Our colleague and collaborator George Hamilton Bowen, Jr., passed away November 1, 2009 in Ames, Iowa. George was born June 20, 1925 in Tulsa, Oklahoma to George and Dorothy (Huntington) Bowen. He married Marjorie Brown June 19, 1948 in Redondo Beach, California; they had five children, with eight grandchildren and five great-grandchildren at the time of his death. George H. Bowen's third or perhaps his fourth career was in astronomy. He was drafted into the navy in 1944, at the end of his first year as a student at Caltech, and ended his war-time service as an electronic technician on the aircraft carrier Shangri-La. He later said "In just nine months, starting from scratch (Ohm's law!), we learned an amazing amount - not by memorization, of course, but by study and real understanding of the basic function of the most advanced AC circuits then being used for instrumentation, measurements, communications, control systems, and much more." He gained a confidence that he could quickly and accurately diagnose and solve technical problems that stood him well in future work. One accomplishment he took particular pride in was figuring out how the radar control used cams and gears to solve the trigonometry for accurate pointing. He also described how the captain was alarmed when weather conditions changed so that refraction no longer showed them distant, small boats around the curvature of Earth. After the war, George Bowen returned to undergraduate and eventually graduate study at Caltech, where he was recruited to the biophysics research group headed by future Nobel Laureate Max Delbrück. George often described his joy in working with these first-rate scientists and finding himself accepted as a part of the effort. He finished his BS with honors in 1949 and his PhD in 1953 with a thesis on "Kinetic Studies on the Mechanism of Photoreactivation of Bacteriophase T2 Inactivated by Ultraviolet Light" involving work with E Coli. This work was supported by grants from the U

    Cowley, Charles

    2011-12-01

    Professor Benjamin F. Peery, Jr. died at his home in Silver Spring, MD of natural causes on 30 November 2010. His full life began in St. Joseph, MO (home of the Pony Express) on 4 March 1922. His father was a railway mail clerk, so his family moved frequently. Most of his childhood was spent in southeastern Minnesota. He enlisted in the army in 1942, and served in campaigns in North Africa and Italy. After his discharge in 1945, he enrolled in the University of Minnesota, earning a BS in Physics in 1949. One of his early hobbies was to build and fly model airplanes. His intention to pursue aeronautical engineering changed to physics, but after receiving a MS in physics from Fisk University in 1955, he decided on a career in astronomy. He told the editors of the PBS series The Astronomers (1991, in which his career is highlighted) he thought it was shamefully absurd not to know what made the stars shine. So he began PhD studies in astronomy at the University of Michigan (Ann Arbor). His dissertation was on the complex eclipsing binary VV Cephei, where a compact hot star passes behind a cool giant star, revealing the structure of that giant's atmosphere. This task was especially demanding because of the complexity of the system's spectrum and the formidable array of observations assembled by Ben's advisor, Dean McLaughlin. Fortunately, Ben's strong physics background enabled him to design and construct one of the first oscilloscope measuring engines, which his fellow students called the PeeryScope. The final (1961) dissertation is an impressive combination of observational and astrophysical analysis. His degree was obtained in 1962; he had already begun a career at the University of Indiana, where he taught and did research (1959--1976). The Indiana years were highly productive. In addition to his own research, he was advisor on six PhD dissertations, and a master's thesis. Several of his students have also had productive careers. An ADS search on his students' names

    Ralph Robert Robbins, Jr., died on 2 December 2005, in Kyle, Texas. His wife, Maria Elena Robbins, his daughters Julia Robbins Kelso and Stephanie Juarez Balles, his son Matthew Juarez, and five grandchildren survive him. Bob was on the faculty at the University of Texas from 1968 until his retirement in 2003. Bob was born in Wichita, Kansas, on 2 September 1938, the only son of Mildred and Ralph Robert Robbins, Sr. Guided by his high school's policy to provide a practical education to children of working-class parents, Bob began high school with a heavy dose of vocational courses until the results of a test indicated his special talent in mathematics. He was awarded a full scholarship to Yale University, graduating magna cum laude in mathematics in 1960. He won the Warner Prize in Mathematics at Yale that year. He received his Ph.D. in 1966 with a dissertation entitled "The Triplet Spectrum of Neutral Helium in Expanding Nebulae" from the University of California at Berkeley. His interest in college teaching was ignited at this time through summer teaching positions at San Mateo California Junior College and the Ohio State University. Following a year at Texas as a McDonald Observatory Post-doctoral Fellow, Bob taught for a year in the physics department of the University of Houston before returning to the University of Texas at Austin as an Assistant Professor of Astronomy in 1968. He was promoted to Associate Professor in 1972. Bob's research in the early 1970s on theoretical studies of helium was of vital importance to astronomers for over three decades. These pioneering calculations became vital to observational astronomers in the mid-1990s as interest grew in the primordial helium produced by the Big Bang. Bob's interest and influence in education was international in scope. In the summers 1968-1970, he was a government consultant in Mathematics in East Pakistan (now Bangladesh). He consulted with the government that was preparing a master plan for technical

    2003-01-01

    The cause of the difference in J-R fracture resistances of AISI Type 347 GTAW welds which had almost same amounts of chromium carbides were investigated by the microstructural observations. As a result, the difference in the fracture resistances with the morphologies of the retained δ-ferrites in Type 347 welds were observed. The fracture resistance of the weld which had mostly vermicular type δ-ferrites was inferior to the weld which has lacy and acicular mixed type δ-ferrites. Therefore, it was deduced that the morphology of δ-ferrites affected the J-R fracture resistances of Type 347 welds

    2016-01-01

    With the objective of analyzing aspects related to the perception of working conditions and their impact on health in the teachers and professors who work for the Universidad Nacional de Cuyo (UNCuyo) in Mendoza, Argentina, this work analyzes the results of the Primer Censo de Condiciones y Salud Laboral [First Census on Health and Working Conditions]. The census was conducted in late 2013 in two academic units (one at the high school level and the other at the university level), including 193 educators. The exploration set out to characterize the teaching staff and the conditions affecting their health, primarily with respect to psycho-social health. In order to do, so a self-administered questionnaire was applied, the dimensions of which were discussed in sensitivity workshops with educators who helped to formulate the data collection instrument. Among the primary results emerge the physical and emotional burnout of these highly skilled workers, owing to the combined effect of their committed response to the demands of their work and the deterioration (both material and symbolic) of the conditions in which they carry out that work.

  2. Genesis of sandstone-type uranium deposits in the Sierra Pintada district, Mendoza, Argentina: a Moessbauer study

    Labenski, F.; Saragovi-Badler, C.

    1982-01-01

    The genesis of sandstone-type uranium deposits in the Cochico Group (Permo-Triassic) of the Sierra Pintada district, San Rafael, Mendoza, has been studied. This is the most important uranium district in Argentina. Uranium sources, uranium transport and precipitation are discussed. Uraninite and brannerite, the main uranium minerals, occur within the matrix of sandstone. Several phenomena can be deduced regarding the depositional environment. Where oxygen was available, precipitation of hydrated ferric oxides occurred; γFe 2 O 3 .nH 2 O varieties (identified by Moessbauer spectroscopy) precipitated in the upper levels of the aquifer, where CO 2 partial pressure was lower, giving reddish or reddish-brown beds. The CO 2 partial pressure also determines the distribution of biogenic agents such as bacteria. Bacteria thus find a more favourable environment for their development and action in upper levels of an aquifer. In the corresponding horizons local reduction occurred where UO 2 precipitated; therefore the highest uranium concentrations correspond to sandstone levels with reddish or reddish-brown pigment. These pigments have been identified by Moessbauer spectroscopy. (Auth.)

    Full Text Available During the last decade of the XIX century and the first two decades of the XX, the argentine province of Mendoza underwent substantial territorial, economical and society changes due to the advance of the capitalism, that formed one of the first regional economy of the country: the viticulture industry. The capitalist development produced an unknown economic expansion in which all the indicators increased in number: extent of the agrarian cultivation, wine vault installment, raise of the capacity of wine elaboration, technological improvement. Pertaining to society land subdivision, enterprise class arising and enlargement of the middle class. However, the majority of the popular sectors, enlarged by the overseas immigration, suffered life conditions characterized by low incomes which were maintained in face values during the studied period, and home and health problems that derived in the propagation of serious contagious disease and high children death rate.

    The increasing demand for fresh fruits has led to the development of new techniques in farming and in harvest and postharvest areas. Special care has been taken to ensure that the use of pesticides reconciles pest control with a low impact on the environment and human health. The presence of pests of economic importance, among them, the Medfly (Ceratitis capitata Weid.), led to the search for alternative techniques of control. The Medfly was first recorded in the United States in 1901, and in Argentina in 1934. The use of the sterile insect technique (SIT) began to develop around 1950. Improvement in the technique has produced promising results world-wide, especially in the breeding of sexing strains, which allows the release of sterile males only. The National Service of Agrifood Quality and Protection (SENASA) of Argentina, coordinates the National Program of Control and Eradication of Fruit Flies (PROCEM). PROCEM has divided Argentina into five different regions. This is according to quarantine regulations, and control and eradication activities to be undertaken. Actually, the Mendoza and San Juan provinces, and the Patagonia Region, have adhered to PROCEM. They have ongoing regional programmes in their respective areas. Mendoza and the Central Valleys of San Juan (Tulum, Ullum and Zonda) are included in the New Cuyo Region, Phase I, where the main objectives are: eradication of the Medfly; verification of the quarantine status; creation of a Medfly free area and exports to Medfly free markets. SIT is the main technique used in Mendoza for Medfly eradication. The Institute of Quality and Protection of Mendoza (ISCAMen) is in charge of the programme in the Province of Mendoza. Mendoza policies for Medfly eradication and the use of SIT, are based on: a growing area of 290,000 ha of vegetable and fruits (vineyards, stone, pome and nut orchards) of high quality, with favourable agroecological conditions and geographical isolation, exports of fresh fruits for the

    The aim of the present study was to analyze the nutritional status and body composition of children from San Rafael, Mendoza, avoiding urban and rural categorization by generating subpopulations as a function of their socio-environmental characteristics. A cross-sectional study was performed in 3,596 schoolchildren from 4.0 to 13.9 years of age. Body weight, height, upper arm circumference, and triceps skinfold were measured. Body mass index, total muscle, and fat areas of the arm were calculated. To estimate nutritional status and body composition, the NHANES III reference was used. The socio-environmental variables were surveyed using a structured questionnaire. These variables were processed by categorical principal-component analysis (catPCA). The catPCA allowed the differentiation of four groups, three with urban characteristics (high urban, medium urban, impoverished urban), and a rural group. Stunting occurred at a higher rate in the impoverished urban group, and the occurrence of underweight children was higher in the rural group. The prevalence of excess weight varied in the range of 20-26%. The latter value corresponded to children of the high urban group, who also did not show reduced muscle mass. Children from San Rafael presented differences in nutritional condition and body composition associated with pronounced socio-environmental heterogeneity. Thus, we could observe a gradient from the "high urban" group, with better social, economic, and sanitation conditions and at the same time a more obesogenic environment to the "impoverished urban" and "rural" groups, whose vulnerability reflected a higher prevalence of child undernutrition and the association with excess weight and reduced muscle mass.

    Full Text Available Crustal seismicity in northwestern Mendoza Province in Argentina, corresponding to the transition zone between the Chilean-Pampean flat subduction zone (26.5–33.5°S and the Southern Central Andes normal subduction zone to the south, is studied in order to i identify its relationship with the mapped structure, ii determine deformational mechanisms and iii constrain the geometry of the fold and thrust belt in the lower crust. Through this, we aim to determine which are the structures that contribute to Andean construction, east of the Frontal Cordillera in Argentina and at the western Principal Cordillera in Chile. Data from a temporary local seismic network are reprocessed in order to achieve a precise location of hypocenters and, whenever possible, to build focal mechanisms. Results are interpreted and compared with previous seismic studies and structural models. Analyzed seismicity is grouped around the eastern front of Frontal Cordillera, with hypocenters mainly at depths of 25–40 km. Contrastingly, earthquakes in the Principal Cordillera to the west are located at the axial Andean sector and Chilean slope, with depths shallower than 15 km. Obtained focal mechanisms indicate mainly strike-slip displacements, left lateral at Frontal Cordillera and right lateral at Principal Cordillera. Based on these observations, new possible structural models are proposed, where seismogenic sources could be either associated with inherited basement structures from the Cuyania-Chilenia suture; or correspond to deep-blind thrusts linked with a deeper-than-previously-assumed decollement that could be shared between Frontal Cordillera and western Precordillera. This deeper decollement would coincide in turn with the one determined from receiver function analysis for the eastern Sierras Pampeanas in previous works, potentially implying a common decollement all through the fold and thrust belt configuration. Apart from this, a new interpretation of

    Full Text Available En el presente artículo analizamos cómo funcionarios de la Municipalidad de Lavalle representan e interpelan a las comunidades indígenas huarpe situadas en el área no irrigada del noreste de Mendoza, área situada en el departamento de Lavalle. Éste se encuentra dividido socioterritorialmente en dos espacios. Uno irrigado, caracterizado como área de progreso, de producción agrícola y de herencia europea y el otro no irrigado, representado como área de atraso, de producción ganadera y de herencia precolonial. A partir de un análisis etnográfico, analizamos cómo el municipio gestiona local y cotidianamente la diversidad étnica, cultural, económica y política. Concluimos que las formas con que los funcionarios interpelan a las comunidades indígenas y a sus integrantes son en base a un doble movimiento, uno de reconocimiento explícito y el otro de individualización, invisibilización y deslegitimación hacia las mismas. Al invisibilizar a las comunidades como sujetos colectivos, funcionarios municipales intentan dar una identidad común que incorpore a los espacios irrigados y no irrigados y a sus poblaciones como pertenecientes a un mismo territorio, el departamental, a la vez que mantenga la jerarquización entre ambos. Al realizar este movimiento, el municipio se erige como el unificador y contenedor de ambos espacios y de los distintos grupos socio-étnicos que los integran.

    Spontaneous fermentations are still conducted by several wineries in different regions of Argentina as a common practice. Native Saccharomyces strains associated with winery equipment, grape and spontaneous fermentations of Malbec musts from "Zona Alta del Río Mendoza" region (Argentina) were investigated during 2001 and 2002 in the same cellar. Low occurrence of Saccharomyces on grapes and their limited participation during fermentation were confirmed. Strain sequential substitution during fermentation was observed. Between 30% and 60% of yeast population at the end of fermentation was coming from yeasts already present in the winery. A stable and resident Saccharomyces micro-flora in the winery was confirmed. It exhibited a dynamic behaviour during season and between years. Commercial strains were found during fermentation in different percentages, but their presence on winery equipment was low. The present work represents a first approach to winery yeast and spontaneous fermentation Saccharomyces population dynamics in an important viticultural region from Argentina that has never been characterized before. The results obtained have an important significance for the local industry, showing for the first time the real situation of the microbial ecology of alcoholic fermentation in an industrial winery from Mendoza, Argentina.

Les glaciers du massif de l’Aconcagua ont amorcé un important retrait depuis la fin du Petit Âge de Glace. Or la disparition de ces glaciers risque d’entraîner une modification des régimes hydrologiques qui, jusqu’à présent, se caractérisaient par de hautes eaux estivales. Ce pic estival pourrait à l’avenir être atténué et remettre en cause les stratégies de gestion de la ressource en eau. Nous faisons ici le point sur les variations récentes de l’englacement et tentons de dessiner un scénario prospectif.Mendoza area is highly vulnerable to the global warming. The glaciers of the Aconcagua massif are currently shrinking, this trend of retreat began at the end of the Little Ice Age. The disappearance of glaciers may modify hydrological regimes. The discharge is currently at maximum during summer (related to glacier melt, but the peak discharge may occur during spring (related to snow melt in the next future. In this paper we synthesize the recent variations of the glaciers and propose a pattern of future variations.

This contribution shows the main characteristics of the talc mineralization related to the Río de Las Tunas ultramafic bodies in the Salamanca Mining District, Frontal Cordillera of Mendoza province. According to the parageneses defined on the studied samples, three generations of talc were established: 1º crystallized in metaperidotites and related to the prograde stage of the regional metamorphism; 2º crystallized inreaction zones (mostly in the talc zone developed at the boundary between metaperidotites and their country-rocks.These reaction zones evidence a metasomatic process due to geochemical gradient between the ultramafic body and their country-rocks. This process was developed during the retrogression of the regional metamorphic cycle. 3º Talc present in shear-zones that cut across the ultramafic bodies. The extreme serpentinization of the ultramaficbodies is concentrated in shear-zones where the serpentine is subsequently replaced by talc ± carbonates related with a hydrothermal stage. Aqueous fluids relatively enriched in CO2 flowed through these shear-zones causing the cease of serpentine formation favoring the talc and/or carbonates. Mined talc deposits are those in shear zones and reaction zones. They are mostly industrial-, asbestine- or talcschist-type. The talc related to the hydrothermal stage can locally reach first and extra qualities.

    Full text.S235JR carbon steel is one of the most popular steels used in Lebanon. It is imported by steel dealers and is widely used by all fabricators and manufacturers of steels for many structural purposes and applications. This kind of steel has good ductile properties as well as excellent weldability. It is still known by its previous designation St 37-2 or E 24-2. S235JR is produced in many shapes and thicknesses such as steel plates, sheets, angles and different other geometric shapes. Standard chemical and mechanical tests were conducted and reported on S235JR hot-rolled structural low-carbon mild steel specimens collected from Lebanese steel market. The main objective of this work is to assure the compliance of these properties with those set by the steel manufacturer. The above mentioned tests were performed at the laboratories of the Industrial Research Institute (IR) in Lebanon to assure the quality and credibility of the results. related European and American standards were presented as references and compared with the achieved results. Discussion was presented to show the similarities and differences between S235JR steel samples and standard requirements. Some of the reasons for such differences were discussed. Sufficient data was furnished through this work for the public and mainly for the Lebanese Standard Organization LIBNOR to easily adopt and implement the EN 10025:1993 European standard that can be applied in Lebanon concerning the most commonly used hot rolled low carbon structural steel. A follow up concerning adopting and implementing EN 10025:1993 will be briefed

Los materiales recuperados, la mayoría de ellos termoalterados y muy fragmentados, incluyen macrorrestos arqueobotánicos (principalmente Zea mays y Phaseulus vulgaris, restos óseos (algunos elementos identificados como Lama sp., fragmentos de distintos recipientes cerámicos y de artefactos de molienda.  Finalmente, se discuten prácticas asociadas con la alimentación y la subsistencia, con especial referencia a la producción y consumo de maíz en el área.   Palabras clave: alimentación, subsistencia, maíz, Mendoza   Abstract We present the study of a refuse deposit associated with feeding activities in the archaeological site Agua Amarga (Tupungato department, Middle West of Mendoza province. This is a residencial site of multiple activities located in the foothill in Valle de Uco, to 1000 masl. We dated ceramics and vegetal remains that locate the context in the late period and during regional inca domination. Our goal is to study strategies of processing, consumption and discarding of foods that also contribute in the discussion on the prehispanic strategies of subsistence in the North and Center of Mendoza province.

    Full Text Available In this article we propose to undertake a reconstruction of the development of the 'Estación Enológica', next to 'Escuela Nacional de Vitivinicultura', between 1904 to 1920 in Mendoza province. This study is of vital importance as we consider this place was a pioneer center in the achievement of scientific and technical studies. These were the basis for the consolidation of quality wine industry , which had many shortcomings by then, and they triggered changes in Mendoza's agroindustry. Besides, Estación Enológica became a meeting place for people who graduated from that school to share experiences and concerns. Apart from carrying out the reconstruction of the development, we will also investigate possibilities of applying these studies to vineyardsEn el presente artículo nos proponemos realizar una reconstrucción de la trayectoria de la Estación Enológica de Mendoza, anexa a la Escuela Nacional de Vitivinicultura, desde 1904 a 1920. El mismo cobra vital importancia en tanto la consideramos un centro pionero en la realización de estudios científicos y técnicos que sirvieron de base a la consolidación de una vitivinicultura de calidad -y que por entonces contaba con múltiples deficiencias- y un impulsor de cambios técnicos en la agroindustria local. A su vez, su importancia radicaría en que fue un espacio aglutinador de las experiencias e inquietudes de los enólogos graduados de la mencionada Escuela. Por último, nos referiremos a las posibilidades de recepción y divulgación de los estudios entre los vitivinicultores

    Full Text Available En Mendoza las aguas subterráneas son un recurso natural indispensable para la subsistencia y de gran importancia para el desarrollo provincial, ya que tienen un valor no solo económico y estratégico, sino también social y ambiental. La prevención de la sobreexplotación de los acuíferos y de la contaminación de estas aguas constituye una de las preocupaciones más serias a la que se enfrentan los encargados de gestionar su uso eficiente. Para ello resulta necesario aplicar políticas de ahorro y conservación, contar con un moderno Derecho de aguas preciso, claro, coherente y conservacionista, encaminado a dar soluciones eficaces a los problemas que hoy se nos presentan y que la gestión se realice con rectitud, transparencia y respetando la Constitución y la leyes.

  7. Determination of J-R curve from only one experimental test on one sample

    Lebey, J.; Roche, R.L.

    1983-01-01

    Increasing attention has been given in fracture mechanics to the use of the J concept not only as a criterion of the onset of crack propagation, but also as an aid in the study of propagation stability. As a consequence, there is a need to determine the variation of J with crack extension, this being usually presented in curves known as J-R curves. Earlier methods for determining such curves used several specimens. The present paper describes a procedure avoiding any direct measurement of the crack length and giving a correct value of J when crack propagation occurs. (author)

    In order to face the challenges in healthcare this century, it is essential that surgeons understand modern leadership principles. One of the greatest leaders in history was Dr. Martin Luther King, Jr., who provides a shining example of level-5 leadership for us to study. The study of leadership principles of great leaders can provide us with practical methods of conflict resolution as well as inspiration to keep us engaged and focused. As leaders of the medical community, we face numerous challenges, including discovering and implementing new treatments for disease, providing care for the indigent, overcoming educational challenges such as incorporating the ACGME Core Competencies into our surgical training and promoting diversity in education. Achieving these goals is often hindered by the environment in which we labor-nearly 50 million are uninsured, the rising cost of medical care is currently at 16% of the GNP, and reimbursement rates are falling-which makes the practice of surgery a significant challenge. Effective leadership will be paramount in achieving these goals. In this editorial, which summarizes a presentation given to the Surgical Section of the annual National Medical Association meeting, five important leadership principles that are important for surgeons have been selected and related to the outstanding leadership of Dr. Martin Luther King, Jr.

  10. Evaluation of J-R curve testing of nuclear piping materials using the direct current potential drop technique

    1986-08-01

    A method is described for developing J-R curves for nuclear piping materials using the DC Potential Drop (DCPD) technique. Experimental calibration curves were developed for both three point bend and compact specimen geometries using ASTM A106 steel, a type 304 stainless steel and a high strength aluminum alloy. These curves were fit with a power law expression over the range of crack extension encountered during J-R curve tests (0.6 a/W to 0.8 a/W). The calibration curves were insensitive to both material and sidegrooving and depended solely on specimen geometry and lead attachment points. Crack initiation in J-R curve tests using DCPD was determined by a deviation from a linear region on a plot of COD vs. DCPD. The validity of this criterion for ASTM A106 steel was determined by a series of multispecimen tests that bracketed the initiation region. A statistical differential slope procedure for determination of the crack initiation point is presented and discussed. J-R curve tests were performed on ASTM A106 steel and type 304 stainless steel using both the elastic compliance and DCPD techniques to assess R-curve comparability. J-R curves determined using the two approaches were found to be in good agreement for ASTM A106 steel. The applicability of the DCPD technique to type 304 stainless steel and high rate loading of ferromagnetic materials is discussed. 15 refs., 33 figs

El primero, de ganadería comercial con agricultura subordinada, estaba centrado en el negocio de compra de ganado en el este del país, su engorde en los oasis mendocinos y su exportación a Chile. La modernización capitalista impuso el modelo agroindustrial vitivinícola orientado al mercado interno formando una de las primeras economías regionales de Argentina. El análisis de los modelos muestra las características centrales de cada uno y el proceso de grandes transformaciones económicas, sociales, políticas y territoriales que experimentó la provincia.This paper studies the two economical and social models that were in vogue in Mendoza between 1870 and 1915 which was oudined by the author's research. The commercial livestock with subordinate agriculture was centered on the buying of cattle in the eastern part of the country, its fattening in the oasis of Mendoza and its export to Chile. The capitalist modernization imposed the viticulture agro industrial model directed to the internal market. This model developed one of the regional economy of Argentine. The analysis of these two models shows the principal characteristics of each and the process of great economical, social, politics and territorial transformations of the province.

  12. A new methodology for the evaluation of the J-R curve

    International Nuclear Information System (INIS)

    Donoso, J. R.; Zahr, J.; Landes, J. D.

    2005-01-01

    A new methodology for the construction of J-R curves for ductile materials, based upon the analytical integration of the P-ν relation, is presented. This method is based on the Common and Concise Formats, and on a postulated crack growth law, that relates the amount of stable crack growth with plastic displacement. The model developed, denoted asnC and C, reproduces quite well the experimentally obtained P-ν, Δa-ν and J-Δa curves. The results suggest that the amount of stable crack growth in a ductile material follows a power-law behaviour in its dependence with plastic displacement. This methodology may be used to evaluate instability conditions, through the adequate analytical treatment of the P-ν and J-Δa relations. (Author) 35 refs

  13. The Son's Fault: Martin Luther King, Jr.'s Search for and Recovery of Sonship.

    Hinds, Jay-Paul

    2018-04-01

    This article examines the role of sonship in the psychological and spiritual development of men. In using the methodology of psychobiography, I explore the life history of Martin Luther King, Jr. to analyze his search for and recovery of sonship. I propose that sonship helps men rebel against and, in the end, overcome the feelings of inadequacy that are experienced in their struggles to achieve manhood, particularly within the father-son dyad. The scholarship of pastoral theologian Donald Capps is instructive in this regard, in that he suggests that sons should be allowed to search for a male figure, a father-substitute, who can affirm, not disdain or reject, this state of sonship. In the end, what is often viewed as a negative act of regression-i.e., the recovery of and return to sonship-is recognized instead as a positive one that assists a man in his journey toward wholeness.

    This article is a retrospective review of patients who presented to Martin Luther King, Jr./Drew Medical Center with gunshot wounds and had either isolated or associated injuries to the hand. The following is an account of those injuries noting the location, soft-tissue or bony involvement, and interventional methods that were implemented in the treatment of these patients who resided primarily in South Central Los Angeles. Prompt evaluation and initiation of treatment is essential in the management of both high- and low-velocity gunshot wounds so as to decrease the potential morbidity that often follows. Society must also look at the prevalence of these injuries and address the underlying issues that often are the root of the acts of violence.

    Full Text Available El deshielo de la nieve acumulada durante el invierno en la cuenca alta del río Mendoza constituye el principal suministro de agua para la agricultura, la industria y el consumo humano en los sectores bajos adyacentes. Sin embargo, a pesar de su gran importancia, hay muy pocos estudios que permitan conocer y entender la variabilidad espacial y temporal de la nieve en este sector de los Andes Centrales de Argentina. En este trabajo presentamos una técnica para cuantificar la evolución diaria de la cobertura nival en esta cuenca basada en la integración de imágenes de los sensores MODIS Aqua y Terra para el período 2000 y 2014. La técnica muestra disminución en la pérdida de información por presencia de nubosidad y fue realizada utilizando herramientas y funciones de los lenguajes de programación Libres R y BASH. Las series de cobertura de nieve obtenidas muestran importantes variaciones estacionales con aumentos de la cobertura nival en invierno (58% de cobertura máxima en promedio y reducciones significativas en verano. Asimismo, se observa una importante variabilidad interanual con claras diferencias entre años secos (ej. 2010, con 12% de cobertura promedio y nevadores (ej. 2005, 32% de cobertura anual promedio. Los mapas de cobertura nival muestran además que los sectores con mayor persistencia de nieve coinciden con la ubicación de glaciares, en los sectores más elevados, protegidos y de menor insolación de la cuenca. Los resultados brindan información novedosa y relevante para conocer y entender de forma más completa la distribución y variabilidad de la cobertura nival en este sector de la cordillera. Los mismos pueden servir de base para múltiples aplicaciones incluyendo el modelado hidrológico de la cuenca del río Mendoza contribuyendo al manejo racional de sus recursos hídricos.

    Full Text Available La agricultura de regadío en zonas áridas favorece la degradación de la Materia Orgánica del suelo (MO, por lo que suelen aplicarse enmiendas orgánicas con la finalidad de restaurar el contenido de MO y mejorar la disponibilidad de nutrientes para los cultivos, aunque no siempre con resultados concluyentes. En este trabajo se analizan, de manera comparativa, cuatro ensayos con diferentes sistemas de aplicación de enmiendas orgánicas (prácticas agrícolas, tipo de enmienda, dosis, frecuencia y forma de aplicación y combinación con fertilizantes químicos en oasis de regadío de Mendoza (Argentina, con la finalidad de establecer las prácticas de manejo más adecuadas para restaurar las diferentes fracciones de MO del suelo (ácidos húmicos y fúlvicos y sustancias no húmicas. El contenido de MO aumentó en el 40% de los casos analizados (n=92 y no sufrió modificaciones en el resto, mientras que los ácidos fúlvicos también aumentaron en el 40% de los casos, pero disminuyeron en el 30%. Contrariamente, los ácidos húmicos sufrieron más disminuciones que aumentos (39% vs. 26% de los casos. Estas diferencias se explican por las prácticas de manejo agrícola y las técnicas de aplicación de las enmiendas, concluyendo que: a todas las prácticas de aplicación de enmiendas aumentan en el corto plazo la MO; b la fracción humificada aumenta en el corto plazo, con la aplicación superficial sin laboreo; y c el agua de riego con alto contenido de desechos orgánicos disminuye el efecto positivo de las enmiendas sobre la MO. Por tales motivos, las prácticas de manejo recomendadas para lograr la restauración de la MO del suelo en los oasis de regadío de Mendoza son: aumentar la dosis y la frecuencia en la aplicación de enmiendas, y reducir el laboreo y el uso de aguas de reuso.

    2018-01-01

    Full Text Available This paper provides some theses to enrich studies on the conformation and characterization of nineteenth century Argentinean ruling groups. For this purpose, the article takes as its object of study the political teams of the Mendoza province that emerged during the second half of the 19th century, and presents solid empirical evidence to identify a set of 725 political actors responsible of embodying and activating the dynamics of the provincial state. This information has been analyzed with quantitative methods and qualitative tools such as prosopography, sociological interpretations and sociability analyses, allowing us to distinguish several features of the local leadership. A wide variety of documents—official records, departmental dispatches, press of the time— was used to investigate these questions, in order to explore the variables related to the unfolding of these actors’ political careers: their socio-professional profile, their continuity or permanence in public service positions, and the projection of their itineraries. As a whole, the article constitutes a contribution to current historiographical debates about the relative complexity of the nineteenth century political system and the role of provincial and local political groups in the process of shaping the Argentine national state. This study also represents a substantive advance in regard to literature about elites and ruling teams, which has been based on meager and unsystematic data, producing hasty generalizations that have nevertheless been taken as valid indicators to define a broad political spectrum.

    Energy use in the built environment is globally recognized as a key issue for sustainable urban development. In tempered-cold arid regions with a generous solar resource, adequate design and technology can substantially reduce the energy demand for space and water heating in urban buildings. This study assessed the solar potential of low-density urban environments in the city of Mendoza, Argentina. The results of the study will be used to develop technical guidelines for urban and energy planning agencies and professionals involved in the production of habitat. The study included the following successive steps: (i) selection of a representative sample of analysis units (city blocks); (ii) selection of a series of urban and building variables; (iii) definition of indicators accounting for solar masking, building's potential use of the solar radiation on the whole urban area, and availability of adequate collecting areas to satisfy high percentages of the energy demand in low-density urban environments; and (iv) insolation of potential collectors simulated by a graphic-computational model developed in the R and D unit. Only the results for solar space heating are presented in this paper. The results, direct and statistical, indicate that it is technically feasible to meet the target solar fractions. At the same time, by means of the solar recycling of existing building stocks, it is possible to considerably reduce the environmental impacts due to the extraction of materials from, and the disposal of solid wastes into, the ecosystem.

    Energy use in the built environment is globally recognized as a key issue for sustainable urban development. In temperate-cold arid regions with a generous solar resource, such as those of western Argentina, adequate design and technology can substantially reduce the energy demand for space and water heating in urban buildings. The solar potential of low-density residential urban areas in the city of Mendoza's Metropolitan Area (MMA), has been studied earlier in this research. Several indicators of the solar potential were elaborated. They provide necessary information when planning and designing new urban structures or refurbishing existing ones. However, a more direct indicator, relating the available solar radiation during a heating season to the space volume to be heated, the Volumetric Insolation Factor (VIF), seems to be of most practical use as far as contributing a helpful evaluation indicator, to the above mentioned design processes. The present study follows the methodological steps used in the former research, evaluating comparatively the results of a Graphic-Computational Model and a Multiple Linear Regression Statistical Model. As in the earlier study, the good fit of both models' results clearly point at the reliability of the statistical procedure and its valuable contribution of a simplified calculation tool as its by-product.

    Full Text Available This study described a group of strains obtained from a slaughter house in Mendoza, in terms of their pathogenic factors, serotype, antibiotype and molecular profile. Ninety one rectal swabs and one hundred eight plating samples taken from carcasses of healthy cattle intended for meat consumption were analyzed. Both the swab and the plate samples were processed to analyze the samples for the presence of virulence genes by PCR: stx1, stx2, eae and astA. The Stx positive strains were confirmed by citotoxicity assay in Vero cells. The isolates were subsequently investigated for their O:H serotype, antimicrobial susceptibility and molecular profile by Random Amplification of Polymorphic DNA (RAPD. Twelve E.coli strains were identified by their pathogenicity. Nine were from fecal origin and three from carcasses. Three strains carried the stx1 gene, three the stx2 gene, two carried eae and four the astA gene. The detected serotypes were: O172:H-; O150:H8; O91:H21; O178:H19 and O2:H5. The strains showed a similarity around 70% by RAPD. Some of the E.coli strains belonged to serogroups known for certain life-threatening diseases in humans. Their presence in carcasses indicates the high probability of bacterial spread during slaughter and processing.

    Back-arc volcanism in the western Argentinian provinces of Mendoza and Neuquén has been widespread from the Miocene to historic times. We present a detailed investigation of profiles through two of the major Miocene volcanic areas of the region, the neighboring Huantraico and LaMatancilla plateaus......, including new 40Ar/39Ar age results of major and trace elements as well as Nd, Sr and Pb isotopic data. Four million years of eruptions from 24.4 ± 0.3 Ma (2σ) of alkali olivine basalts with OIB-type incompatible trace element enrichments at La Matancilla (~36.50°S) provide evidence for the presence of back......-arc mantle devoid of subduction-related components. In contrast, the lower Huantraico lavas (~37.30°S) require an atypical back-arc mantle, almost devoid of arc-like components (e.g. low La/Ta = 15–18 and Ba/La = 12–18), but with a more depleted isotopic signature (e.g. 87Sr/86Sr, 0.7033–0.7037) than...

    The paper presents the test results of the S235JR steel susceptibility to damage under the influence of hydrogen. The test of mechanical properties was performed on the basis of a static stretch test of non-hydrogenated samples and after cathodic polarization. Electrochemical measurements for the assessment of corrosion resistance of non-hydrogenated and hydrogenated steels were carried out using open circuit potential measurement and registering of potentiodynamic polarization curves in a three-electrode measuring system. Hydrogenation was carried out for between 3 and 24 hours in a solution of 0.1 N sulfuric acid (VI) with the addition of 2 mg/dm 3 of arsenic oxide (III) at an electric current density of 10 mA/cm2. The hydrogen content in the steel before and after saturation with hydrogen was determined using the analyzer. Fracture samples after tensile test were observed using scanning electron microscope. The results of the research showed that as the hydrogen concentration in the examined steel increased (the lengthening of the saturation time), the deterioration of its mechanical and electrochemical properties occurred.

    This year the Manuel Lujan Jr. Neutron Scattering Center (LANSCE) ran an informal user program because the US Department of Energy planned to close LANSCE in FY1994. As a result, an advisory committee recommended that LANSCE scientists and their collaborators complete work in progress. At LANSCE, neutrons are produced by spallation when a pulsed, 800-MeV proton beam impinges on a tungsten target. The proton pulses are provided by the Clinton P. Anderson Meson Physics Facility (LAMPF) accelerator and a associated Proton Storage Ring (PSR), which can Iter the intensity, time structure, and repetition rate of the pulses. The LAMPF protons of Line D are shared between the LANSCE target and the Weapons Neutron Research (WNR) facility, which results in LANSCE spectrometers being available to external users for unclassified research about 80% of each annual LAMPF run cycle. Measurements of interest to the Los Alamos National Laboratory (LANL) may also be performed and may occupy up to an additional 20% of the available beam time. These experiments are reviewed by an internal program advisory committee. This year, a total of 127 proposals were submitted. The proposed experiments involved 229 scientists, 57 of whom visited LANSCE to participate in measurements. In addition, 3 (nuclear physics) participating research teams, comprising 44 scientists, carried out experiments at LANSCE. Instrument beam time was again oversubscribed, with 552 total days requested an 473 available for allocation.

    Thursday 23 June, CERN saw an unlikely and much savoured meeting between two old colleagues and friends: General Charles F. Bolden, Jr. and Professor Claude Nicollier.   Bolden and Nicollier were separately invited to CERN for different reasons - Charles Bolden had been invited by Professor Samuel Ting to visit the newly built and now fully operational Payload Operation and Control Centre of the AMS collaboration and Claude Nicollier had been invited by the Theory Department to give a colloquium. They were delightfully surprised when they met at the entrance of the main building. Bolden and Nicollier served together in the Space Shuttle Program and were trained by NASA during the 1980’s where they became close friends. On 24 April, 1990, Bolden piloted the Space Shuttle Discovery into orbit with the Hubble telescope in the payload bay. Though Nicollier did not accompany Bolden during the Hubble launch, he did return to the telescope 3 years later on board the Space Shuttle Ende...

    Multivariable models were developed for predicting J-R curves from available data, such as material chemistry, radiation exposure, temperature, and Charpy V-notch energy. The present work involved collection of public test data, application of advanced pattern recognition tools, and calibration of improved multivariable models. Separate models were fitted for different material groups, including RPV welds, Linde 80 welds, RPV base metals, piping welds, piping base metals, and the combined database. Three different types of models were developed, involving different combinations of variables that might be available for applications: a Charpy model, a preirradiation Charpy model, and a copper-fluence model. In general, the best results were obtained with the preirradiation Charpy model. The copper-fluence model is recommended only if Charpy data are unavailable, and then only for Linde 80 welds. Relatively good fits were obtained, capable of predicting the values of J for pressure vessel steels to with a standard deviation of 13--18% over the range of test data. The models were qualified for predictive purposes by demonstrating their ability to predict validation data not used for fitting. 20 refs., 45 figs., 16 tabs

    Alberto Urrets-Zavalía Jr was born in Córdoba (Argentina) in 1920. Chairman of the Department of Ophthalmology of the National University of Córdoba and founder of the Cornea and Glaucoma Surgical Center in the same city, in 1956 he created the first residency programme in Ophthalmology in his country. He founded the first Eye Bank and introduced one of the first argon laser photocoagulators in South America. He authored around 200 scientific presentations and publications, describing new findings and clinical entities. Thus, his individualisation of the cyclovertical component in strabismus contributed to important evolution of ideas concerning pathogenesis and therapy in oculomotor disorders of infancy. He was the first to propose the dehydration of the vitreous body in glaucoma patients before ocular surgery and developed a fixation pick and scleral depressor for retinal detachment surgery. He also described a new technique, the V-Z procedures for the correction of senile ectropion. In 1968, he published his Décollement de la rétine, considered a masterpiece in retinal detachment literature for many years. Urrets-Zavalía died in his native city at the age of 89. His prolific scientific and educational contributions make him one of the most brilliant and influential ophthalmologists of the 20th-century. © The Author(s) 2014.

    The preschool years offer an opportunity to interrupt the trajectory toward obesity in black children. The Hip-Hop to Health Jr. Obesity Prevention Effectiveness Trial was a group-randomized controlled trial assessing the feasibility and effectiveness of a teacher-delivered weight control intervention for black preschool children. The 618 participating children were enrolled in 18 schools administered by the Chicago Public Schools. Children enrolled in the 9 schools randomized to the intervention group received a 14-week weight control intervention delivered by their classroom teachers. Children in the 9 control schools received a general health intervention. Height and weight, physical activity, screen time, and diet data were collected at baseline and post-intervention. At post-intervention, children in the intervention schools engaged in more moderate-to vigorous physical activity than children in the control schools (difference between adjusted group means=7.46 min/day, p=.02). Also, children in the intervention group had less total screen time (−27.8 min/day, p=.05). There were no significant differences in BMI, BMI Z score, or dietary intake. It is feasible to adapt an obesity prevention program to be taught by classroom teachers. The intervention showed positive influences on physical activity and screen time, but not diet. Measuring diet and physical activity in preschool children remains a challenge, and interventions delivered by classroom teachers require both intensive initial training and ongoing individualized supervision.

    Cyclic J-R behaviour of a reactor pressure vessel steel using different methods available in literature has been examined to identify the best suitable method for cyclic fracture problems. Crack opening point was determined by moving average method. The η factor was experimentally determined for cyclic loading conditions and found to be similar to that of ASTM value. Analyses showed that adopting a procedure analogous to the ASTM standard for monotonic fracture is reasonable for cyclic fracture problems, and makes the comparison to monotonic fracture results straightforward. - Highlights: • Different methods of cyclic J-R evaluation compared. • A moving average method for closure point proposed. • η factor for cyclic J experimentally validated. • Method 1 is easier, provides a lower bound and direct comparison to monotonic fracture.

This study was conducted during two consecutive vintages to assess its influence on the general composition, sensory attributes and preference of Vitis vinifera L. cv Malbec wines. Batches of 120 kg of grapes harvested from vines with different degrees of (visual symptoms of the disease were separately vinified. Grapes were grouped in three treatments: T1, grapes from vines with no symptoms; T2, grapes from vines with 10%–50% symptoms; and T3, grapes from vines with 50%–100% symptoms. Basic analyses of the grapes prior to crushing, and basic wine analysis were undertaken, together with spectrophotometric analyses of the wines after three months of bottle aging. The kinetics of alcoholic fermentation (AF was followed daily and additionally the wines were assessed by a sensory panel. T3 grapes were characterized by comparatively lower initial sugar contents and higher titratable acidity. The AF kinetics were unaffected in the wines arising from the diseased grapes. There was no clear-cut effect of the disease on the wines’ pH, volatile acidity, and total acidity; however, the later spectrophotometric analyses showed that the total phenolic index was the highest in T2 wines for both vintages. In 2005, the color index (CI was higher in T3 and showed the lowest value in 2006. The sensory properties of the wines were different in the two vintages. In 2005, T2 and T3 wines were perceived as having higher color intensity, violet hue and spicy notes, T2 being the most preferred wine. In 2006, T1 and T2 showed a much better sensory

Más allá de explicar la incidencia que tuvieron en la refracción de otras corrientes de pensamiento, las tesis interpretativas que ven a Mayo como un momento de reafirmación de la hispanidad y que niegan su sentido emancipatorio, así como los recorridos biográficos de sus autores, revelan redes de sociabilidad intelectual que bajo la nominación de nacionalismo encubrían no pocas especificidades, al mismo tiempo que revelaban las vinculaciones existentes con la escuela historiográfica sevillana, por entonces usina intelectual del franquismo y nutriente del pensamiento nacionalista conservador y autoritario de los años sesenta.Research on the nationalism present in post- Peronism in Mendoza has allowed us to retrieve a number of intellectual itineraries that exemplify the complexity of a period in which the circulation and traffi c of ideas show not only strong identity mutation processes, but also the crystallization of undoubtedly anachronistic positions.

    Full Text Available Uno de los retos actuales a nivel de diseño y planificación urbana consiste en la trasformación de las urbes actuales en modelos de ciudades que contemplen el cuidado del medio ambiente y la mejora de la calidad de vida de los habitantes. Los estudios realizados denotan que los conglomerados de baja densidad poblacional son los más contaminantes (Cepeda y Mardaras, 2004; Norman, Maclean, Asce & Kennedy, 2006 en consecuencia una de las mejoras urbanas a fomentar es la densificación de las ciudades. No obstante, los niveles poblacionales no son únicos y estándares, sino que deben encontrarse en relación con las características propias de cada sector. Este trabajo tiene como objetivo principal desarrollar una metodología de cálculo que permita determinar niveles poblacionales máximos contemplando los requerimientos bioclimáticos de la ciudad y garantizando el acceso al sol más igualitario para todos los habitantes de la urbe. La misma es aplicada en el Área Metropolita de Mendoza y denota que las dimensiones de las manzanas y el ancho de las calles limitan la capacidad constructiva del sector y, en consecuencia, la cantidad de personas albergable. Los resultados obtenidos dan cuenta de las densidades poblaciones máximas para los distintos sectores, las que varían entre los 49 y 400 habitantes por hectárea, siendo las manzanas angostas con calles estrechas las de menor capacidad.

    Full Text Available La temperatura es la variable que más incide en el desarrollo de Lobesia botrana (Den & Schiff, cuya relación ha sido estudiada mediante modelos matemáticos, como el de Touzeau. En Mendoza, en 2010 se registró la aparición de L. botrana. El objetivo de este trabajo es ajustar el modelo de Touzeau para predecir el comportamiento de la polilla. El estudio se realizó en un viñedo cv. Malbec desde 2012. Se emplearon trampas de feromonas. La temperatura se registró con un sensor datalogger. Se calculó la integral térmica con la fórmula de Touzeau con un umbral de 10ºC desde el 1 de julio de cada año. Los resultados indicaron que el primer vuelo se desarrolló el 18 y el 20 de octubre con 204,05 ± 10,73 grados día, el segundo en la primera decena de diciembre con 728,34 ± 41,95 grados día, el tercero durante la última quincena de enero con 1329,08 ± 151,35 grados día y el cuarto a mediados de febrero de 2012 y 2013, respectivamente con 1721,84 ± 116,63 grados día. Estos resultados son útiles para predecir la aparición de la plaga y como herramienta para establecer un sistema de alarma para los productores.

    Full Text Available El control en el intercambio de flujos energéticos interior-exterior y la inercia térmica de los materiales constructivos son características claves de la envolvente de los edificios de bodegas. Esta situación es particularmente importante en el caso de los edificios construidos sobresuelo en climas con temperaturas diarias y estacionales muy variables. En el caso de que la arquitectura no provea la respuesta adecuada, indefectiblemente se recurre al consumo de energía auxiliar. La bodega S.A., ubicada en Mendoza, Argentina, consume energía auxiliar equivalente a 2.500 kW por año. Dicha bodega sobresuelo presenta dos tipos de envolvente vertical: una tradicional en adobe (λ = 0.81W/mK y otra contemporánea en chapa galvanizada sin aislación (λ = 45 W/mK. El objetivo de este trabajo es analizar los aspectos de materialidad, inercia térmica e intercambio de flujos energéticos de envolventes tradicionales y contemporáneas y, comparar los resultados obtenidos con un caso teórico de bodega subterránea. Entre los resultados obtenidos se observa que la envolvente tradicional mantiene las temperaturas interiores entre 8,5 ºC y 10 ºC por debajo de las temperaturas exteriores, mientras que los nuevos espacios con envolventes contemporáneas lo hacen solamente 3 ºC a 5 ºC por debajo de las temperaturas exteriores. En el caso de una bodega subterránea, las temperaturas estarían estables durante el año en 16,5 ºC; esto es, en verano, 20 ºC por debajo de las temperaturas exteriores.

    A tectonically affected Middle Ordovician succession crops out at the Los Guanacos quarry in the sierra de Las Higueras, in the Precordillera of Mendoza, western Argentina. This is represented by the San Juan Formation which is transitionally covered by a mixed carbonate-shaly unit of dark colours, 1.5 metres thick (transfacies) which can be interpreted as the base of the Los Azules Formation. A 5-cm thick intra-bioclastic pack/grainstone bed interbedded in the lower part of this unit has been interpreted as a tempestite. It is characterized both by a millimetre-thick erosional boundary, just above the dark mudstone layer and strong mechanical distribution of bioclasts and intraclasts, suggesting sedimentary structures associated with a storm event of high energy possibly occurring in the middle part of the platform. Towards the bottom, a hummocky structure thin interval, under the dark mudstone, is interpreted as the record of another tempestite event. The mudstone represents the post-storm event reflecting the low energy of the marine water environment. The lenticular layer contains predominantly lingulid shells, trilobites and graptolites, all highly fragmented, which suggests they have been reworked and subsequently mixed and quickly redeposited during a storm event that caused the mortality of these faunas. The trilobites Mendolaspis salagastensis and indeterminate species of Matagnostidae, Illaenidae, Leiostegiidae, Encrinuridae, Telephinidae and Trinucleidae have been recorded for the first time at this locality. The conodont fauna allows the identification of the Yangtzeplacognathus crassus Zone, which indicates the lower Darriwilian (Middle Ordovician). Graptolites assignable to evisograptus cf. Levisograptus austrodentatus and Levisograptus sp. are described for the first time in the studied area and biostratigraphic implications validate the early Darriwilian age for the bearing levels. Finally, based on the studied records, correlation with different

    The preschool years provide a unique window of opportunity to intervene on obesity-related lifestyle risk factors during the formative years of a child's life. The purpose of this study was to assess the impact of a preschool-based obesity prevention effectiveness trial at 1-year follow-up. RCT. Primarily African American children (aged 3-5 years, N=618) attending Head Start preschool programs administered by Chicago Public Schools. Eighteen preschools were randomly assigned in 2007-2008 to receive either (1) a 14-week teacher-delivered intervention focused on healthy lifestyle behaviors or (2) a 14-week teacher-delivered general health curriculum (control group). The primary outcome, BMI, was measured at baseline, postintervention, and 1-year follow-up. Diet and screen time behaviors were also assessed at these time points. Multilevel mixed effects models were used to test for between-group differences. Data were analyzed in 2014. Significant between-group differences were observed in diet, but not in BMI z-score or screen time at 1-year follow-up. Diet differences favored the intervention arm over controls in overall diet quality (p=0.02) and in subcomponents of diet quality, as measured by the Healthy Eating Index-2005, and in fruit intake (servings/day, excludes juice) (p=0.02). Diet quality worsened more among controls than the intervention group at 1-year follow-up. The adaptation of Hip-Hop to Health Jr. produced modest benefits in diet quality but did not significantly impact weight gain trajectory. Not unlike other effectiveness trials, this real-world version delivered by Head Start teachers produced fewer benefits than the more rigorous efficacy trial. It is important to understand and build upon the lessons learned from these types of trials so that we can design, implement, and disseminate successful evidence-based programs more widely and effectively.

    The paper is concerned with the nucleation, growth and coalescence of microdefects in the form of voids in S235JR steel. The material is known to be one of the basic steel grades commonly used in the construction industry. The theory and methods of damage mechanics were applied to determine and describe the failure mechanisms that occur when the material undergoes deformation. Until now, engineers have generally employed the Gurson-Tvergaard- Needleman model. This material model based on damage mechanics is well suited to define and analyze failure processes taking place in the microstructure of S235JR steel. It is particularly important to determine the critical void volume fraction fc , which is one of the basic parameters of the Gurson-Tvergaard-Needleman material model. As the critical void volume fraction fc refers to the failure stage, it is determined from the data collected for the void coalescence phase. A case of multi-axial stresses is considered taking into account the effects of spatial stress state. In this study, the parameter of stress triaxiality η was used to describe the failure phenomena. Cylindrical tensile specimens with a circumferential notch were analysed to obtain low values of initial stress triaxiality (η = 0.556 of the range) in order to determine the critical void volume fraction fc . It is essential to emphasize how unique the method applied is and how different it is from the other more common methods involving parameter calibration, i.e. curve-fitting methods. The critical void volume fraction fc at void coalescence was established through digital image analysis of surfaces of S235JR steel, which involved studying real, physical results obtained directly from the material tested.

    Full Text Available Las plazas concebidas bajo el concepto de “plaza jardín” -modelo dominante en las ciudades de Latinoamérica- generan efectos microclimáticos a escala urbana y edilicia dado que actúan como fuente de enfriamiento nocturno. En contextos de baja y media densidad, dicho efecto está asociado fundamentalmente al diseño de la plaza: núcleo central predominantemente semi-sellado alrededor del cual se distribuyen áreas verdes a modo de bosques y prados. Sin embargo, en el caso de la ciudad de Mendoza-Argentina, la tendencia a la redensificación del tejido urbano, como estrategia de control del crecimiento urbano, limita los beneficios que proporcionan las configuraciones actuales de plazas. Es por ello que este trabajo evalúa el impacto de incrementar la dimensión de la plaza en el comportamiento térmico de la misma y su influencia sobre el microclima del entorno mediato, como alternativa para potenciar sus beneficios en áreas urbanas de alta densidad. Con tal fin, se seleccionaron tres casos de estudio, dos de ellos de una superficie equivalente a una manzana urbana –10000m2–, emplazados en entornos de media y alta densidad, y un caso de mayor superficie -40000m2-, inserto en un contexto de alta densidad. Tales casos fueron monitoreados térmicamente en la estación verano, durante un periodo de 21 días, mediante el uso de microadquisidores de datos del tipo HOBO H08-003-02. Se caracterizaron las condiciones radiativas a partir de la determinación del factor de visión de cielo (SVF. Los resultados obtenidos muestran que, al incrementar las dimensiones de la “plaza jardín”, sus diferentes estructuras -núcleo central, bosque, prado- presentan menores temperaturas respecto a su entorno durante todo el día. En consecuencia, constituye una estrategia eficiente para mejorar las prestaciones del espacio abierto respecto a sus efectos microclimáticos en entornos urbanos de alta densidad. Si bien dicha

Se expone el proceso llevado a cabo para la constitución de la Mesa de Educación Ambiental en la provincia de Mendoza, Argentina. A partir de la discusión sobre la problemática local del Cambio Climático y los requerimientos de  medidas de adaptación, se propone el espacio en el año 2013 mediante la firma de una declaración de interés entre 4 instituciones. En el año 2014 toma fuerza la iniciativa mediante la definición de objetivos y metas concretas, con la participación activa más de 10 instituciones de diversos ámbitos: educativas, científicas, técnicas, órganos de gobierno, organizaciones no gubernamentales, municipios y privados.  En el año 2015 se consolida mediante la firma de un Acta Constitutiva. Su objetivo principal es articular acciones que permitan a la comunidad tener mejores herramientas para enfrentar la complejidad de la problemática y el cuidado de nuestro ecosistema.  Se considera un espacio proactivo y participativo, abierto a la incorporación de nuevos actores. Procura establecer lineamientos de políticas públicas sobre Educación Ambiental, orientadas a la promoción de comunidades sustentables. Asimismo, aspira a ser un  órgano de articulación reconocido por ley. En su corto recorrido, ha avanzado en su organización interna, capacitaciones a docentes, sugerencias al Proyecto de Ley de Educación de la Provincia como la inclusión de la obligatoriedad de la enseñanza de la Educación Ambiental y la creación de la figura de referente ambiental en los establecimientos educativos, como así también organiza jornadas, concursos y eventos educativos a nivel provincial.

El objetivo del trabajo fue analizar las prevalencias de sobrepeso y obesidad en niños urbanos y rurales del Departamento de San Rafael, Mendoza, en relación a las condiciones socio-ambientales. Se realizó un estudio antropométrico transversal en 1176 individuos de 6 a 12 años. Se relevaron peso corporal, talla y pliegues subcutáneos tricipital y subescapular. El sobrepeso y la obesidad fueron determinados utilizando los criterios del International Obesity Task Force. El patrón de distribución adiposa se analizó mediante el índice Subescapular/Tricipital (IST. Un valor de IST>1 indicó centralización adiposa. El relevamiento socio-ambiental se realizó mediante encuesta autoadministrada. Los datos fueron procesados por análisis de componentes principales categórico (catACP. El catACP discriminó cuatro grupos según su condición socio-ambiental: Urbano: (Alto, Medio y Empobrecido y Rural. Las prevalencias para sobrepeso fueron de 14,4% y para obesidad de 7,6%, siendo las diferencias sexuales no significativas. La población con sobrepeso presentó en ambos sexos, valores de IST<1. En los varones obesos el IST fue >1 a partir de los 9 años y en las mujeres a los 9 y 12 años. El sobrepeso se distribuyó homogéneamente en los cuatro grupos, en tanto que la obesidad fue mayor en el grupo con características rurales. Los resultados dan cuenta del creciente aumento del sobrepeso con distribución homogénea e independiente de la condición socioeconómica. La obesidad en cambio, se concentra principalmente en la zona rural.

    Full Text Available A yeast strain identified as Geotrichum sp. JR1 was able to use acetonitrile as the sole carbon and nitrogen source. The strain grew in 0.5 to 2M acetonitrile. Ammonia generation as enzymatic product during the strain growth indicates the presence of an acetonitrile degrading enzyme. Acetic acid and acetamide were detected during assays with the resting cells cultivated in acetonitrile, indicating the presence of nitrile and amide degrading enzymes. This paper is the first to describe the use of acetonitrile as the sole carbon and nitrogen source by a yeast.Uma linhagem de levedura identificada como Geotrichum sp.

Asimismo se evaluó la evolución de los records de las pruebas de 100 metros en los cuatro estilos, los 400, 800 y 1500 metros libres ambos sexos en pileta de 25 y 50 metros. Se consideró la cantidad de clubes participantes, los nadadores con licencia nacional en los distintos años y las nominaciones para Seleccionados Nacionales en las distintas décadas. No se obtuvo diferencias estadísticamente significativas entre la evolución de los records realizados en pileta de 25 con la de 50 metros. Se comprobó que disminuyó tanto la cantidad de clubes participantes en los torneos desde 1950 hasta el año 2000 como la de nadadores federados. El estudio nos revela que el nivel competitivo de los nadadores se ha elevado por el aumento en las nominaciones a Seleccionados Nacionales. Como conclusión obtuvimos que posiblemente estos valores obtenidos se deban a la evolución en las técnicas de nado y en los métodos de entrenamiento, interrogante que puede servir para próximos estudios y que, en este caso, la cantidad de deportistas no es directamente proporcional a los logros deportivos.------------------------------------------------------------------------------The investigation that we carried out sustains in an exploratory and descriptive study.

    Full Text Available This work analyses the conflict situation present in the province's drylands between goat producers and programmes to combat desertification regarding production practices and the use producers make of natural resources. The case study tackled comprises the north-eastern extreme of Mendoza province. The , which is the hyperarid spot of the region, severely affected by desertification processes, covering an extent of 10,007 km2, and with 3015 inhabitants, where small goat breeding farms predominate. Previous studies indicate that the major causes of desertification in the area are logging of the native woodland and overgrazing which have led to improper livestock production practices. In response to this, the actions to combat desertification commonly point out the need to "raise awareness" and "build capacities" of the producers by initiating processes of change in the production systems. The proposals insist that, if the current level of pressure on resources is maintained, the already serious poverty conditions will grow worse in the future. Nevertheless, despite the efforts and funds invested, the producers seem to stubbornly persist in their present production strategies and in the dynamics of natural resource use derived from them. How to explain their refusal to consider other production options likely to result in higher profit and better environmental balance? How to explain that they act, at least apparently, against their own benefits? Against the explanations that place the producers' "culture" is the most important problem, the present work seeks to cooperate in clarifying these questions through an analysis of the different rationalities that, held by different actors, converge in the area.

Se ha escogido la vendimia (febrero-marzo como período a analizar debido a que la demanda de refrigeración es entonces mayor: toneladas de materia prima (a alrededor de 26-30ºC deben ser procesadas a 8ºC, mientras que las temperaturas exteriores se encuentran alrededor de los 38ºC. Las bodegas seleccionadas tienen la misma cantidad y calidad de producción y similar tamaño edilicio, pero diferente manejo y materialidad en la envolvente. La bodega “P” fue construida con paredes de ladrillos tradicionales, con techo metálico con aislamiento térmico y simple vidrio en ventanas; mientras que la bodega “H” se construyó parcialmente con paneles de hormigón armado con aislamiento térmico, techos metálicos con aislamiento y doble vidrio hermético en sus aberturas. Se tomaron mediciones in situ de temperatura del aire, temperatura superficial en la envolvente, humedad relativa y radiación solar, y se estudiaron en relación a los registros de consumos energéticos de cada bodega. Luego, con los datos obtenidos se ajustó un modelo generado con el software Energy Plus, el cual se utilizó para simular alternativas de mejora de la envolvente. Como resultado, ambas bodegas presentaron mejoras. Las temperaturas medidas en bodega P fueron igualadas en un promedio de 18.89°C sin el uso de energía auxiliar. En el caso de la bodega H las temperaturas medidas se optimizaron, logrando un promedio de 21.77°C, otra vez, sin el uso de energía auxiliar. Existe la posibilidad de agregar estrategias de ventilación nocturna usando las temperaturas exteriores las cuales disminuyen en 9,78°C en el período analizado.

    A rolled plate might show different mechanical behaviors from a forging, even though they contain same chemical compositions. Furthermore, it is known that the fracture behavior of a rolled plate is very sensitive to material orientation comparing to a forging. In this study, the J-R fracture resistances of SA533 Gr.B-Cl.1 plate were measured at reactor operating temperature and the material orientation sensitivity was discussed. The decrease of fracture resistance of this kind of low alloy steel at an elevated temperature is known as the effect of dynamic strain aging (DSA). It was attributed to that the carbides and grains elongated to primary rolling direction, so that the aspect ratio of carbides and grains in the specimen with T-L orientation is larger. Generally, the hard second phase could take a roll of trigger point of unstable fracture. It is needed that the fracture surfaces of the tested specimens to be examined profoundly.

    There is a singular unifying reality underlying every biologic interaction on our planet. In immunology, that which does not kill you makes you different. -William B. Miller, Jr. We are experiencing a revolution in our understanding of inner space on a par with our exponentially increasing understanding of outer space. In biology, we are learning that the genetic and epigenetic complexity within organisms is far deeper than suspected. This is a key theme in William B. Miller Jr.'s book, The Microcosm Within: Evolution and Extinction in the Hologenome. We are learning also that a focus on the human genome alone is misleading when it comes to who we really are as biological entities, and in terms of how we and other creatures have evolved. Rather than being defined by the human genome alone, we are instead defined by the "hologenome," the sum of the human genome and the far larger genetic endowment of the microbiome and symbiotic communities that reside within and around us. Miller is a medical doctor previously in private practice in Pennsylvania and Phoenix, Arizona. This book is his first foray into evolutionary theory. His book could have been titled "The Origin of Variation" because this is his primary focus. He accepts that natural selection plays a role in evolution, but he demotes this mechanism to a less important role than the Modern Synthesis suggests. His main gripe, however, concerns random variation. He argues that random variation is unable to explain the origin and evolution of biological forms that we see in the world around us and in the historical record. Miller suggests that, rather than random variation as the engine of novelty, there is a creative impulse at the heart of cellular life, and even at the level of the genetic aggregate, that generates novelty on a regular basis. I probe this assertion in the interview below. He also highlights the strong role of "exogenous genetic assault" in variation and in his immunological model of evolution.

    In 2008, during my participation in the NSF-sponsored Texas Earth & Space Science (TXESS) Revolution professional development program, I was awarded an AS-1 seismograph through IRIS's Seismographs in Schools Program. This program serves to create an international educational seismic network that allows teachers across the country and around the world to share seismic data in real-time using online tools, classroom activities, and technical support documents for seismic instruments. Soon after receiving my AS-1, I founded and began sponsoring the Eagle Pass Jr. High Seismology Team which consists of selected 7th and 8th grade students. Eagle Pass Jr. High is a Title 1 school that serves a predominantly "at-risk" Hispanic population. We meet after school once a week to learn about earthquakes, seismic waves, analyze recorded seismic event data using computer software programming, and correspond with other students from schools around the country. This team approach has been well received by fellow TXESS Revolution teachers with AS-1 seismographs and will be implemented by David Boyd, STEM coordinator for Williams Preparatory Academy in Dallas, Texas this fall 2011. All earthquakes recorded by our seismograph station (EPTX), which has remained online and actively recording seismic data since 2008, are catalogued and then plotted on a large world map displayed on my classroom wall. A real-time seismogram image updates every five minutes and along with all earthquakes recorded since installation can be viewed on our webpage http://www.iris.edu/hq/ssn/schools/view/eptx. During the 2010-2011 school year, my seismology team and I participated in an earthquake research study led by Dr. Cliff Frohlich at the Institute for Geophysics. The study examined seismograms and felt reports for the 25 April 2010 Alice, Texas, earthquake, in order to investigate its possible connection to oil and gas production in the Stratton oil and gas field.

    Full Text Available Foregut in D. hominis (Linnaeus Jr., 1781 as the majority of the larval Diptera somatic tissue, is made up of polytenic cells, and grows at the expenses of the polytenization of its nuclei followed by the increase in size of each cell. The oesophagus, of ectodermic origem, is interiorly covered by a chitinous squamous epithelium that rests upon a very thin basal lamina. This sheet is surrounded by thick muscle bundles. The oesophagus intussuscepts the midgut forming the cardia. The cardia, with three epithelial layers: two internal ones, of ectodermal origin and one external of endodermic origin. At the anterior portion of the cardia, between these two types of epithelium, there is a cluster of small, non polytenic cells, forming the imaginal disk of the foregut. Metamoiphosis begins at the end of the larval period with signs of nuclear degeneration of all the polytenic cells, as well as the increase in number of the imaginal disk ones. The oesophagic portion intussuscepted into the cardia, everts; its cells suffer apoptosis and are replaced by the new cells growing from the imaginal disk. The external layer cells also degenerate and are pinched off into the lumen of the very anterior portion of the midgut. The newly formed oesophagus intussuscepts "de novo" to form the two internal layers of the adult cardia. At the same time the midgut regenerative cells grow anteriorly to form the new external layer of the adult cardia.

    Automatic typewriters, transistor radios, microfiche, black and white television…while considered high-tech in the 1950s, these technologies seem limited when viewed from the 21st century. The same is true for cardiovascular medicine, which back then relied on electrocardiograms and X-rays for most diagnoses. In the 60 years since, advances in medical capabilities have progressed at a staggering pace. Patient research that once required months poring over paper charts is now reduced to hours using electronic medical record databases. Diagnostic images that once took days to process can now be accessed instantly through ultrasound and magnetic resonance imaging. While a half-century ago no one would have imagined accessing any and all information with a 5-second Google search, so too would noninvasive heart surgery been considered unimaginable. Since the 1950s when he graduated from medical school, William L. Winters, Jr., has been a first-hand witness to breathtaking innovations in cardiovascular medicine-both globally and in Houston. Author of Houston Hearts: A History of Cardiovascular Surgery and Medicine at Houston Methodist DeBakey Heart & Vascular Center and long-time medical editor of the Methodist DeBakey Cardiovascular Journal, Dr. Winters sat down with the journal editors this past April to share his insights from the last half-century of medical practice.

    The prevalence of obesity in the United States is a significant public health problem. Many obesity-related risk factors are more prevalent in minority populations. Given the recalcitrant nature of weight loss interventions for adults, prevention of overweight and obesity has become a high priority. The present study reports baseline data from an obesity prevention intervention developed for minority preschool children. Hip-Hop to Health Jr. is a 5-year randomized controlled intervention that targets 3- to 5-year-old minority children enrolled in 24 Head Start programs. Our primary aim is to test the effect of the intervention on change in body mass index. Data were collected on sociodemographic, anthropometric, behavioral, and cognitive variables for the children and parents at baseline. Participants included 416 black children, 337 black parents, 362 Latino children, and 309 Latino parents. Using body mass index for age and sex > or = the 95th percentile as the definition of overweight, 15% of the black children and 28% of the Latino children were overweight. More than 75% of the parents were either overweight or obese. The development of interventions to effectively prevent or control obesity early in life is crucial. These data highlight the escalating problem of weight control in minority populations.

    Copper-64 is an attractive radionuclide for PET imaging and is frequently used in clinical applications. The aim of this study was to perform a side-by-side comparison of the in vitro and in vivo performance of 64Cu-NODAGA-JR11 (NODAGA = 1,4,7-triazacyclononane,1-glutaric acid,4,7-acetic acid, JR11 = p-Cl-Phe-cyclo(D-Cys-Aph(Hor)-D-Aph(cbm)-Lys-Thr-Cys)D-Tyr-NH2), a somatostatin receptor 2 antagonist, with the clinically used sst2 agonist 64Cu-DOTA-TATE ((TATE = D-Phe-cyclo(Cys-Tyr-D-Trp-Lys-Thr-Cys)Thr). In vitro studies demonstrated Kd values of 5.7±0.95 nM (Bmax = 4.1±0.18 nM) for the antagonist 64/natCu-NODAGA-JR11 and 20.1±4.4. nM (Bmax = 0.48±0.18 nM) for the agonist 64/natCu-DOTA-TATE. Cell uptake studies showed the expected differences between agonists and antagonists. Whereas 64Cu-DOTA-TATE (the agonist) showed very effective internalization in the cell culture assay (with 50% internalized at 4 hours post-peptide addition under the given experimental conditions), 64Cu-NODAGA-JR11 (the antagonist) showed little internalization but strong receptor-mediated uptake at the cell membrane. Biodistribution studies of 64Cu-NODAGA-JR11 showed rapid blood clearance and tumor uptake with increasing tumor-to-relevant organ ratios within the first 4 hours and in some cases, 24 hours, respectively. The tumor washout was slow or non-existent in the first 4 hours, whereas the kidney washout was very efficient, leading to high and increasing tumor-to-kidney ratios over time. Specificity of tumor uptake was proven by co-injection of high excess of non-radiolabeled peptide, which led to >80% tumor blocking. 64Cu-DOTA-TATE showed less favorable pharmacokinetics, with the exception of lower kidney uptake. Blood clearance was distinctly slower and persistent higher blood values were found at 24 hours. Uptake in the liver and lung was relatively high and also persistent. The tumor uptake was specific and similar to that of 64Cu-NODAGA-JR11 at 1 h, but release from the tumor

    Full Text Available A search for extremophile enzymes from ancient volcanic soils in El Hierro Island (Canary Islands, Spain allowed isolation of a microbial sporulated strain collection from which several enzymatic activities were tested. Isolates were obtained after sample cultivation under several conditions of nutrient contents and temperature. Among the bacterial isolates, supernatants from the strain designated JR3 displayed high esterase activity at temperatures ranging from 30 to 100°C, suggesting the presence of at least a hyper-thermophilic extracellular lipase. Sequence alignment of known thermophilic lipases allowed design of degenerated consensus primers for amplification and cloning of the corresponding lipase, named LipJ. However, the cloned enzyme displayed maximum activity at 30°C and pH 7, showing a different profile from that observed in supernatants of the parental strain. Sequence analysis of the cloned protein showed a pentapeptide motif -GHSMG- distinct from that of thermophilic lipases, and much closer to that of esterases. Nevertheless, the 3D structural model of LipJ displayed the same folding as that of thermophilic lipases, suggesting a common evolutionary origin. A phylogenetic study confirmed this possibility, positioning LipJ as a new member of the thermophilic family of bacterial lipases I.5. However, LipJ clusters in a clade close but separated from that of Geobacillus sp. thermophilic lipases. Comprehensive analysis of the cloned enzyme suggests a common origin of LipJ and other bacterial thermophilic lipases, and highlights the most probable divergent evolutionary pathway followed by LipJ, which during the harsh past times would have probably been a thermophilic enzyme, having lost these properties when the environment changed to more benign conditions.

El propio genoma humano, la clave de aquello que nos da caracteres especiales y únicos como especie que piensa, se analiza a sí misma y se comunica con especial finura, está entregando sus secretos a los sabios que lo estudian.

    Si eso fuera todo, podríamos celebrar la llegada de nuevo poder para ayudar a nuestros semejantes en el cuidado de su salud, la mejora en su calidad de vida, el combate contra la enfermedad. Pero, al tiempo con los conocimientos científicos y las novedades tecnológicas, han aparecido cambios sociales que construyen un escenario igualmente nuevo para el ejercicio de la Medicina y, al menos en nuestro país, un intento más o menos soterrado para privarnos de nuestra condición de profesionales y ponernos a desempeñar un oficio sujeto a condiciones de actividad comercial; esto, por razones obvias, nos causa profunda preocupación.

    – Como un oficio, es decir, atendiendo sobre todo a la aplicación de conocimientos y habilidades para conseguir una “obra” que cumpla ciertas normas y llene las expectativas de quien “recibe” esa “obra”, que sería el cliente.

    – O, de otro lado, como una profesión, que se estructura alrededor de un compromiso, de base ética, que el profesional

    Full Text Available En la ciudad de Mendoza, Argentina, las viviendas presentan mayoritariamente una baja calidad constructiva en relación con la falta de aislamiento de sus envolventes. Se estima que el 95% de las viviendas existentes no están aisladas en su envolvente vertical y presentan aislamiento insuficiente en techos. En un clima templado continental, con grandes amplitudes térmicas diarias y estacionales, las viviendas presentan inercia térmica como única estrategia bioclimática. En estas circunstancias, las posibilidades de gestión que ofrezca la envolvente -a través de elementos practicables y/o móviles-, son claves para la aproximación al logro del confort interior. El presente trabajo analiza la influencia del uso y gestión de las aberturas en la envolvente a cargo del usuario en una vivienda tradicional, mediante monitoreo higrotérmico, durante 59 días en verano. Para ello, se midieron dos períodos con distintas condiciones climáticas (extremas y moderadas en los que se aplicó la estrategia de ventilación natural nocturna, gracias a la cual se obtuvo 82% de horas en confort. Asimismo, se midió un período sin gestión de las aberturas en la envolvente, es decir, manteniéndolas cerradas; de lo que resultó solo un 6% de horas en confort. Se concluye, en suma, que la intervención comprometida y consciente del usuario mediante el aprovechamiento de la ventilación nocturna, en combinación con la inercia térmica del envolvente, desempeña un papel importante en el logro de condiciones térmicas en interiores que reducen el sobrecalentamiento durante el verano.

    This paper presents the detailed characterization of a single photon counting chip, named CHASE Jr., built in a CMOS 40-nm process, operating with synchrotron radiation. The chip utilizes an on-chip implementation of the C8P1 algorithm. The algorithm eliminates the charge sharing related uncertainties, namely, the dependence of the number of registered photons on the discriminator’s threshold, set for monochromatic irradiation, and errors in the assignment of an event to a certain pixel. The article presents a short description of the algorithm as well as the architecture of the CHASE Jr., chip. The analog and digital functionalities, allowing for proper operation of the C8P1 algorithm are described, namely, an offset correction for two discriminators independently, two-stage gain correction, and different operation modes of the digital blocks. The results of tests of the C8P1 operation are presented for the chip bump bonded to a silicon sensor and exposed to the 3.5- μm -wide pencil beam of 8-keV photons of synchrotron radiation. It was studied how sensitive the algorithm performance is to the chip settings, as well as the uniformity of parameters of the analog front-end blocks. Presented results prove that the C8P1 algorithm enables counting all photons hitting the detector in between readout channels and retrieving the actual photon energy.

    To assess the impact of a culturally proficient dietary/physical activity intervention on changes in body mass index (BMI) (kg/m 2 ). Randomized controlled trial (Hip-Hop to Health Jr.) conducted between September 1999 and June 2002 in 12 Head Start preschool programs in Chicago, Illinois. Intervention children had significantly smaller increases in BMI compared with control children at 1-year follow-up, 0.06 vs 0.59 kg/m 2 ; difference -0.53 kg/m 2 (95% CI -0.91 to -0.14), P = .01; and at 2-year follow-up, 0.54 vs 1.08 kg/m 2 ; difference -0.54 kg/m 2 (95% CI -0.98 to -0.10), P = .02, with adjustment for baseline age and BMI. The only significant difference between intervention and control children in food intake/physical activity was the Year 1 difference in percent of calories from saturated fat, 11.6% vs 12.8% ( P = .002). Hip-Hop to Health Jr. was effective in reducing subsequent increases in BMI in preschool children. This represents a promising approach to prevention of overweight among minority children in the preschool years.

    The setting for this case study is the Dolph Briscoe, Jr. Library, University of Texas Health Science Center at San Antonio, a health sciences campus with medical, dental, nursing, health professions, and graduate schools. During 2008-2009, major renovations to the library building were completed including office space for a faculty development department, multipurpose classrooms, a 24/7 study area, study rooms, library staff office space, and an information commons. The impetus for changes to the library building was the decreasing need to house collections in an increasingly electronic environment, the need for office space for other departments, and growth of the student body. About 40% of the library building was remodeled or repurposed, with a loss of approximately 25% of the library's original space. Campus administration proposed changes to the library building, and librarians worked with administration, architects, and construction managers to seek renovation solutions that meshed with the library's educational mission.

    This study was aimed to assess clinical safety and efficacy of the LVIS Jr. microstent in stent-assisted coil embolization of wide-neck intracranial aneurysms. IRB approved single-center interventional clinical study in 22 patients (10 females, 12 males, mean age 55, age range 33-74 years) for the endovascular treatment of wide-neck aneurysms. After obtaining informed consent, patients were included according to the following criteria: aneurysm fundus-to-neck ratio 4 mm, and a parent vessel diameter of ≤3.5 mm. Primary end point for clinical safety was absence of death, absence of major or minor stroke, and absence of transient ischemic attack. Primary end point for treatment efficacy was complete angiographic occlusion according to the Raymond-Roy Occlusion Classification (RROC) immediately after the procedure and at follow-up after 3 and 6 months on magnetic resonance imaging (MRI). In 20/22 (91 %) of patients, the primary end point of safety was reached; in the two remaining patients, transient ischemic attack, but no permanent deficit was observed; in 16/22 (73 %), efficient occlusion (RROC1) was reached, and in 6/22 (27 %), a residual neck remained (RROC2). Single [seven with antegrade, two in crossover configuration, and four with ''first-balloon-then-stent'' (FBTS) technique] or double-stent (eight patients with Y configuration and one patient with X configuration) deployment was technically successful in all cases. Deployment of the LVIS Jr. microstent in various single- or double-stent configurations is safe and effective to assist the treatment of intracranial wide-neck aneurysms. (orig.)

  5. Structure and dynamics of the gp120 V3 loop that confers noncompetitive resistance in R5 HIV-1(JR-FL to maraviroc.

    Full Text Available Maraviroc, an (HIV-1 entry inhibitor, binds to CCR5 and efficiently prevents R5 human immunodeficiency virus type 1 (HIV-1 from using CCR5 as a coreceptor for entry into CD4(+ cells. However, HIV-1 can elude maraviroc by using the drug-bound form of CCR5 as a coreceptor. This property is known as noncompetitive resistance. HIV-1(V3-M5 derived from HIV-1(JR-FLan is a noncompetitive-resistant virus that contains five mutations (I304V/F312W/T314A/E317D/I318V in the gp120 V3 loop alone. To obtain genetic and structural insights into maraviroc resistance in HIV-1, we performed here mutagenesis and computer-assisted structural study. A series of site-directed mutagenesis experiments demonstrated that combinations of V3 mutations are required for HIV-1(JR-FLan to replicate in the presence of 1 µM maraviroc, and that a T199K mutation in the C2 region increases viral fitness in combination with V3 mutations. Molecular dynamic (MD simulations of the gp120 outer domain V3 loop with or without the five mutations showed that the V3 mutations induced (i changes in V3 configuration on the gp120 outer domain, (ii reduction of an anti-parallel β-sheet in the V3 stem region, (iii reduction in fluctuations of the V3 tip and stem regions, and (iv a shift of the fluctuation site at the V3 base region. These results suggest that the HIV-1 gp120 V3 mutations that confer maraviroc resistance alter structure and dynamics of the V3 loop on the gp120 outer domain, and enable interactions between gp120 and the drug-bound form of CCR5.

    The La Peña alkaline complex (LPC) of Miocene age (18-19 Ma) lies on the eastern front of the Precordillera (32°41ʹ34ʺS, 68°59ʹ48″W, 1400-2900 m a.s.l.), 30 km northwest of Mendoza city, Argentina. It is a subcircular massif of 19 km2 and 5 km in diameter, intruded in the metasedimentary sequence of the Villavicencio Formation of Silurian-Devonian age. It is the result of integration of multiple pulses derived from one or more deep magma chambers, which form a suite of silicate rocks grouped into: a clinopyroxenite body, a central syenite facies with a large breccia zone at the contact with the clinopyroxenite, bodies of malignite, trachyte and syenite porphyry necks, and a system of radial and annular dikes of different compositions. Its subcircular geometry and dike system distribution are frequent features of intraplate plutons or plutons emplaced in post-orogenic settings. These morphostructural features characterize numerous alkaline complexes worldwide and denote the importance of magmatic pressures that cause doming with radial and annular fracturing, in a brittle country rock. However, in the LPC, the attitude of the internal fabric of plutonic and subvolcanic units and the preferential layout of dikes match the NW-SE extensional fractures widely distributed in the host rock. This feature indicates a strong tectonic control linked to the structure that facilitate space for emplacement, corresponding to the brittle shear zone parallel to the N-S stratigraphy of the country rock. Shearing produced a system of discontinuities, with a K fractal fracture pattern, given by the combination of Riedel (R), anti-Riedel (R‧), (P) and extensional (T) fracture systems, responsible for the control of melt migration by the opening of various fracture branches, but particularly through the NW-SE (T) fractures. Five different pulses would have ascent, (1) an initial one from which cumulate clinopyroxenite was formed, (2) a phase of mafic composition represented by

    Full Text Available As well as being a civil rights advocate, Dr. Martin Luther King Jr consistently called for human rights for all. He opposed poverty, racism, imperialism and political disfranchisement as part of an analysis, which viewed inequality not only in American but also in global terms. In order to address poverty and related human rights issues, King proposed a Poor People’s Campaign (PPC. In May 1968, only weeks after King’s assassination, the PPC saw thousands of poor people travel to Washington DC to protest against poverty. The demonstrators occupied sacred space in the nation’s capital by building a temporary community, known as Resurrection City. During preparations for the PPC and in Washington, the activists drew on a rich legacy of adult education from previous civil rights campaigns. The approaches adopted by PPC participants were innovative and represented alternatives to conventional educational practices. These included Freedom Schools, a Poor People’s University, workshops, marches and demonstrations, which assisted the protesters to come together in coalition to challenge dominant hegemonic narratives concerning the causes, nature and scope of poverty. Although ultimately unsuccessful in its aspiration to end economic injustice in America, the PPC undoubtedly laid the seeds for future anti-poverty activism. The article draws on primary source documents and oral testimonies from five archives.

    2002-02-01

    BACKGROUND; The increasing prevalence of overweight among children in the United States presents a national health priority. Higher rates of overweight/obesity among minority women place their children at increased risk. Although increased rates of overweight are observed in 4- to 5-year-old children, they are not observed in 2- to 3-year-old children. Therefore, early prevention efforts incorporating families are critical. The primary aim of Hip-Hop to Health Jr. is to alter the trajectory toward overweight/obesity among preschool African-American and Latino children. This 5-year randomized intervention is conducted in 24 Head Start programs, where each site is randomized to either a 14-week dietary/physical activity intervention or a general health intervention. This paper presents the rationale and design of the study. Efficacy of the intervention will be determined by weight change for the children and parent/caretaker. Secondary measures include reductions in dietary fat and increases in fiber, fruit/vegetable intake, and physical activity. Baseline data will be presented in future papers. The problem of overweight/obesity is epidemic in the United States. Behaviors related to diet and physical activity are established early in life and modeled by family members. Early intervention efforts addressing the child and family are needed to prevent obesity later in life. This paper describes a comprehensive, family-oriented obesity prevention program for minority preschool children. Copyright 2002 American Health Foundation and Elsevier Science (USA).

    International Nuclear Information System (INIS)

    Regulatory regimes that have increased household energy efficiency are of widespread interest to policymakers today. A prominent example is the state of California where electricity intensities in the residential sector have stayed near constant since the 1970s in sharp contrast to nationwide trends in the United States. A structural model of residential energy consumption is used to show that the use of energy intensities alone to evaluate the success of California efficiency programs is misleading and glosses over important policy independent factors. We quantify important effects of price, climate conditions and demographic characteristics on energy consumption in California. We also provide evidence of split incentive considerations in residential energy consumption patterns. We conclude that while state policy may have had some effect on efficiency, caution needs to be exercised in using the California example to inform expectations from similar measures in other regions. - Highlights: • We model electricity and heating fuel consumption in US households. • We use the structural model to estimate price elasticities. • California energy intensities are strongly influenced by policy independent factors. • The role of energy efficiency policy in lowering intensities is limited. • Evidence of split incentive considerations in energy demand

    Full Text Available JJP Valeton Jnr was one of the main founders of the theological current in nineteenth century Holland called 'the ethical theology'. Some of the most prominent members of this current were, like Valeton, Old Testament specialists. One of the main characteristics of the ethicals was their distinction between scientific knowledge and the knowledge of faith. This enabled them to adopt a critical approach to the Bible while at the same time remaining active in the service of the church. In this article it is shown how Valeton applied this principle in his work on the history of Israelite religion. An attempt is made to demonstrate how his insight was more penetrating than that of even the great Abraham Kuenen.

    Full Text Available Aquí se presenta un detallado estado de las investigaciones arqueológicas desarrolladas en el noreste de la provincia argentina de Mendoza. Esta zona es objeto de estudios desde principios del siglo XX. Sin embargo los pulsos de la investigación han registrado etapas de abandono total y de intervenciones selectivas. Los investigadores han partido de los trabajos precedentes para explicar por extensión las modalidades de asentamiento en la totalidad del territorio norte y, sobre todo, del occidente montañoso, que era donde concentraban sus campañas. Esto acabó generando un cuadro de antecedentes desequilibrado y superficial en el conocimiento de dicha área, con implicaciones en el cuadro interpretativo general de la prehistoria local. En este caso, indagamos las posibles causas que dieron lugar a tal proceso, sus vínculos con los enfoques teóricos y metodologías dominantes a lo largo del siglo XX y su relación con la selección de zonas para llevar a cabo estudios de campo en el norte de la provincia. Reflexionamos críticamente sobre los alcances, límites y posibilidades que ofrece la región para profundizar los análisis arqueológicos del poblamiento prehispánico en relación con las condiciones del ambiente y los procesos históricos documentados, proponiendo discutir los enfoques que basan sus explicaciones en hechos dados por sentados y que merecerían antes una discusión en base a la evidencia disponible.

    An analysis of Chandra ACIS data for two relatively bright and narrow portions of the northwestern rim of G266.2–1.2 (a.k.a. RX J0852.0-4622 or Vela Jr.) reveal evidence of a radial displacement of 2.40 ± 0.56 arcsec between 2003 and 2008. The corresponding expansion rate (0.42 ± 0.10 arcsec yr{sup –1} or 13.6% ± 4.2% kyr{sup –1}) is about half the rate reported for an analysis of XMM-Newton data from a similar, but not identical, portion of the rim over a similar, but not identical, time interval (0.84 ± 0.23 arcsec yr{sup –1}). If the Chandra rate is representative of the remnant as a whole, then the results of a hydrodynamic analysis suggest that G266.2–1.2 is between 2.4 and 5.1 kyr old if it is expanding into a uniform ambient medium (whether or not it was produced by a Type Ia or Type II event). If the remnant is expanding into the material shed by a steady stellar wind, then the age could be as much as 50% higher. The Chandra expansion rate and a requirement that the shock speed be greater than or equal to 1000 km s{sup –1} yields a lower limit on the distance of 0.5 kpc. An analysis of previously published distance estimates and constraints suggests G266.2–1.2 is no further than 1.0 kpc. This range of distances is consistent with the distance to the nearer of two groups of material in the Vela Molecular Ridge (0.7 ± 0.2 kpc) and to the Vel OB1 association (0.8 kpc)

  3. ¿Cómo fue que el viñedo adquirió importancia? Significados de las vides, calidades de las uvas, y cambio socio-técnico en la producción vinícola de Mendoza

    over the past few decades. Limiting itself to the Mendoza region, this paper wants to analyze some of the changes observed in vineyards from a socio-technical perspective. Following the way that the definition of quality is (reconstructed, a relationship is sought between vines and wine and the use of certain technologies. The paper shows how the dynamics between social groups and artifacts create different conceptions of quality, which in turn lead to a different role of grapes in the wine making process. It also shows that the changes observed do not necessarily imply a ‘new way’ has taken over an ‘old way’. It rather seems that different social groups are relevant in different technological frames, displacing others.

    Según los diferentes actores implicados en el proceso de producción, el vino argentino ha vivido cambios radicales en las últimas décadas. Limitándose a la región de Mendoza, esta investigación intenta analizar algunos de los cambios observados en los viñedos desde una perspectiva socio-técnica. Siguiendo la forma como la definición de calidad es (reconstruida, se busca comprender la relación existente entre la interpretación de la vid y el uso de ciertas tecnologías. El artículo muestra cómo las dinámicas entre grupos sociales y artefactos crean significados diferentes de calidad, lo que a su vez otorga diferentes papeles a las uvas en el proceso de producción de vinos. También muestra que los cambios descriptos no necesariamente implican que una ‘nueva tradición’ haya reemplazado a una ‘vieja tradición’, sino que diferentes grupos sociales son relevantes en diferentes marcos tecnológicos, desplazando a otros.

    In connection with the problem of the applicability of the characteristic specimen date - i.e. the initiation and stable crack propagation under maximal loads, together with the elastic-plastic material behaviour - to that of actual components, spot-check type beside tests were conducted using wide-plate central crack, central notch (CCT, CNT) and double external crack (DECT) samples. The material in question was an StE 460 steel. A comparison between the determined values shows that the assessed pressure vessel behaviour differs extensively to the values derived from the CCT and CNT specimens. The corresponding results obtained from the CT25 and DECT specimens vary only slightly in the region of interest and correspond to real vessel values. (orig./DG) [de

  12. Obituary: Norman Hodgson Baker, Jr., 1931-2005

    Science.gov (United States)

    Helfand, David J.

    2005-12-01

    Norman H. Baker, a key contributor to the foundation of modern stellar pulsation theory and former editor of the "Astronomical Journal", died on 11 October 2005 in Watertown, New York near his beloved summer home in Natural Bridge. He succumbed to complications of Waldenstrom's macroglobulinemia, a bone marrow lymphoma that he had successfully surmounted for twenty-two years. Norm, as he was known to all, was born 23 October 1931 in Fergus Falls, Minnesota to Norman Hodgson and Jeannette (née Lieber) Baker. He attended the University of Minnesota where he met the first of many lifelong astronomical friends, Bill Erickson. He received his BA in 1952. He went on to do his PhD, "Radiation from Particle Interactions which Create Current," at Cornell University under Phil Morrison. He then moved to a postdoctoral position at the Max Planck Institut für Physik und Astrophysik in München with the intent of pursuing his work in plasma physics with Ludwig Biermann and Arnulf Schlüter. However, Rudolf (Rudi) Kippenhan snatched him away to pursue what became his lifelong interest, stellar physics. This was the dawn of the era in which electronic computers were becoming practical for scientific calculations, and Norm immediately adopted this new tool. Indeed, he remained at the forefront of computing technology throughout his life: He was certainly the first member of the Astronomy Department at Columbia to buy a Mac, and was undoubtedly one of the few emeritus professors in the world known by all the administrative staff as the first person to turn to when stumped by a computer problem. Following his first paper with Kippenhan on stellar rotation, Norm turned his attention to stellar pulsations, a topic he would pursue throughout his career. His 1962 paper in "Zeitschrift für Astrophysik" on pulsational models of Cepheids (Baker and Kippenhan 1962, 54, 155) is a classic in the field. The first figure displays the three dimensional model of the atmospheric absorption coefficient as a function of log P and log T. Sophisticated three-dimensional computer images being many years in the future, it was contructed from a folded and bent sheet of grid paper which was subsequently photographed. Using extensive numerical analysis, the paper showed that stars in the δ Cephei region of the H-R diagram were ``pulsationally unstable due to the destabilizing effect of the He+ region.'' This paper, along with those of Zhevakin, Cox, and Christy, established our modern understanding of pulsational instability in horizontal branch stars. His second paper with Kippenhan the following year brought convection into the problem; this topic became another lifelong theme of Norm's research that he subsequently pursued with Douglas Gough. His most cited work, carried out a decade later with van Albada, was an attempt to understand the properties of horizontal branch stars. It synthesized for the first time stellar evolution theory and the insights gained from studies of stellar pulsations. Between 1961 and 1965, Norm held no fewer than five positions. After a year on the west coast at the Convair Science Research Lab in San Diego, he landed in the New York area to pursue pulsations, oscillating among the Goddard Institute for Space Studies, the Institute for Advanced Study in Princeton, Yale, and New York University. In 1965, he was hired as an Assistant Professor in the Department of Astronomy at Columbia University by Lo Woltjer, and remained at Columbia until he retired in 2003. As a teacher, he was deeply appreciated by undergraduate and graduate students alike for lectures that were models of clarity, for his out-of-class assistance which was generous and unstinting, and for incorporating into his courses modern numerical techniques which served the students well throughout their careers. In 1975 when Woltjer returned to Europe, Norm took over the editorship of the "Astronomical Journal", a position he held (shared in the last few years with Leon Lucy) for a decade. His scrupulous integrity and forthright honesty served him, and the Society, well. Despite his scathing intolerance for administrative stupidity, he also managed to complete successfully a term as Chair of the Department of Astronomy. (This author, who currently holds the Chair and shares the intolerance, has yet to fathom the gracious equanimity Norm displayed.) His early interest in brewing beer during graduate school at Cornell (where he co-founded the Old Undershirt Brewing Company) was transformed in later life into an expertise in German wines. The precision that marked his research extended to every aspect of his private life. I had the distinct pleasure of subletting his apartment during my first year on the faculty at Columbia while he was on leave in Europe. We spent most of the year trying to imagine how we could ever restore it to the state of perfect organization in which we found it. Norm is survived by his wife and constant companion of thirty years, psychiatrist Doris Blum Nagel, by his sister Dr. Jean Trousdale, and brother Dr. Richard C. Baker, two nieces, three nephews, and by several generations of undergraduates, graduate students, postdocs, and colleagues who hold fond memories of his patience, kindness, humor, and quiet "joie de vivre".

  13. Obituary: Harding Eugene (Gene) Smith, Jr., 1947-2007

    Science.gov (United States)

    Lonsdale, Carol; Soifer, Tom

    2009-01-01

    Harding Eugene Smith Junior, or Gene, as he was known to family, friends, and colleagues, passed away after an automobile accident in Encinitas, California, on 16 August 2007. He was 60 years old. Gene had recently retired from UCSD after thirty years of service. A memorial service was held at Quail Botanical Gardens in Encinitas, California, on 23 August 2007. A web page is dedicated to his memory at http://harding.smith.muchloved.com, where contributions of memories are invited. Gene was born in San Jose, California in 1947, to Harding Eugene Smith Senior, and Bernice Smith (nee Smith). Harding Smith Senior was an air-force navigator; therefore Gene spent his childhood moving from one air-force base to another. Although an only child, Gene was very close to his cousin Meg, whom he lived nearby to in Gilroy for a time, and the two were like brother and sister. The elder Harding Smith was lost in action over Cambodia in the mid-sixties. Gene was a dedicated student, a boy scout, and a Presidential Scholar. He majored in Physics at Caltech, where he also took a lively interest in the football team and the Glee Club, and was elected a House Officer. To his close friends, he was known at Caltech as Smitty, and the closest of them was Rob Drew, who gave a glimpse into that period of Gene's life at the memorial: "Gene arrived early at campus his first year, in response to an invitation to join the football team. Gene's size and features reminded the head coach of a long-forgotten player named 'Johnson.' After a few days of confusion, Gene simply replaced the name on his helmet. 'Johnson!' coach would yell, 'get in there!' If Johnson was going to get to play, Gene was going to be the best Johnson available!" Gene spent the summer of 1966 working at Kitt Peak, where his lifetime love of observing with ground-based telescopes began, though he learned some things the hard way, such as the fact that trying to squeeze 40,000 numbers onto a computer that stored only 32,000 resulted in blown fuses. In a final letter of that summer back to Drew he wrote: "My summer is now complete. I have achieved the highest pinnacle in my quest for fulfillment. Striking a blow for humanity I just blew the whole Kitt Peak CDC3200 computer system. Those fuses were nothing compared to this!" Gene's graduate work, on the metal abundances in HII regions of nearby galaxies, was done at Berkeley, where Hyron Spinrad was his thesis advisor. He loved observing and spent numerous fun nights at Lick, Kitt Peak, Cerro Tololo, Keck, and many other observatories. He joined Margaret Burbidge at UCSD for a postdoctoral fellowship, and joined the teaching faculty there in 1978. Gene spent his entire professional career at UCSD. His research ranged from the study of quasar absorptions lines to the astrophysics of Ultra-luminous Infrared Galaxies. He was a key participant in UC-wide astronomy support, including being the chair of the science-advisory committee for the Ten Meter Telescope project, which later "morphed" into the Keck Observatory. His contributions to enabling that project were both essential and unheralded. Gene was a dedicated and enthusiastic teacher. One of his favorite undergraduate classes gave him the opportunity to dress up in Renaissance garb and pretend to be Galileo, while the experiment most loved by his students was when they got to attempt to drop an egg on his head from several stories high. Gene was also an outstanding advisor and mentor, and both his first post-doc, Rick Puetter, and his last graduate student, Brian Siana, were able to attend his memorial service and provide some special memories of their experiences with him. Rick recalled a memorable trip to Cerro Tololo when they packed up two infrared spectrometers for the trip, and everything conceivable went wrong, from inspections at the airport to spectrometer parts broken on the plane and instrument failures at the observatory, to finally being completely clouded out. Brian recounted: "I spent countless cloudy nights listening to Gene's stories that began with "When men were men and giants roamed the Earth . . . ". I still don't know what that means, but it always preceded some sage advice." Besides astrophysics, Gene's passions included horse riding (the faster the better), sailing, hiking, the northern California coast and mountains, black-and-white photography, extremely strong coffee, travel (especially European castles and cathedrals, and any road-less-traveled that he came across), cooking and fine restaurants, Native American pottery, basketware and kachinas, and classical music. He also loved to sing, and friends would say he had a song for every occasion. He was a dedicated and enthusiastic supporter of all causes environmental and conservationist, and among figures he greatly admired were John Muir and Ansel Adams. Gene is survived by his wife of eighteen years, Dr. Carol Jean Lonsdale; step-daughter Kimberley; daughter Tamsyn; cousins Meg and Chris Bailey; in-laws Colin and Marilou Lonsdale, and Graham Lonsdale; niece Joanna; and two nephews Greg and Wes. He is also greatly missed by his many friends and colleagues, his golden retriever, Jasper, and his palomino horse, Sundance.

    2014-01-01

    Inevitably, there are times in a nation’s history when its hopes, fears and confidence in its own destiny appear to hinge on the fate of a single person. One of these pivotal moments occurred on the early morning of May 5, 1961, when a 37-year-old test pilot squeezed himself into the confines of the tiny Mercury spacecraft that he had named Freedom 7. On that historic day, U.S. Navy Commander Alan Shepard carried with him the hopes, prayers, and anxieties of a nation as his Redstone rocket blasted free of the launch pad at Cape Canaveral, hurling him upwards on a 15-minute suborbital flight that also propelled the United States into the bold new frontier of human space exploration. This book tells the enthralling story of that pioeering flight as recalled by many of the participants in the Freedom 7 story, including Shepard himself, with anecdotal details and tales never before revealed in print. Although beaten into space just three weeks earlier by the Soviet cosmonaut Yuri Gagarin, Alan Shepard’s h...

    In 1851, John Russell Hind announced that a star previously observed by him to be very red had become bluish white in colour. We show that this star, HD 38451, is a ninth magnitude shell star which presumably was ejecting a shell when Hind first observed it. From high dispersion coude spectra, low dispersion IUE spectra and ground-based photometry we find HD 38451 to be a normal A2IV shell star. Its current value of E(B-V) approx. ident to 0.14 is probably caused by interstellar rather than circumstellar reddening. There remains a problem to reconcile the large amount of reddening present when Hind first observed the star with its evidently small diminution in visual brightness at that time. (author)

  1. Aiming at Targets: The Autobiography of Robert C. Seamans, Jr.

    Seamans, Robert C., Jr.

    1996-01-01

    Bob Seamans originally was inspired to write this book for his family and friends. That is a large audience. By his own count his immediate family numbers twenty-four, not counting brothers and cousins and their families. His friends are uncounted but surely run to hundreds. As one of them and as a colleague at NASA, I am pleased and honored that he asked me to write this foreword. While written in Bob's unique and informal style, this autobiography has significance for many readers beyond his large circles of family and friends. Leaders and students of large, complex technological endeavors should be able to learn much from reading how Bob faced the daunting technical and management challenges in his career. As the title of this book implies, Bob has always set high goals for himself and then kept his eyes focused on both the necessary details and the broader picture. His ability to shift smoothly among jobs that required seemingly disparate abilities and skills speaks volumes about his insight, dedication, and enthusiasm for achievement. The book spans a truly remarkable life story. Bob first takes us through his growing up, education, and early professional and family life. Next he focuses on the crucial years when he was the general manager of NASA. Then he moves on to his career in the top jobs at the Air Force, the National Academy of Engineering, and the Energy Research and Development Administration. Finally, he touches on his later leadership activities in the academic and business worlds. Aiming at Targets is a series of fascinating topical vignettes covering his professional life. Taken together, like broad brushstrokes in an impressionist painting, they give a better picture of Bob Seamans and his work than a detailed recitation of facts and dates could hope to do. This is a cheerful account of an interesting and successful career. The book is full of good stories, with many memorable characters. Like the proverbial sundial, it counts the sunny hours. It is a good read. But it has its serious side. Bob's career wasn't all fun. The Apollo 204 fire, which killed three astronauts, was a terrible climax to his time at NASA. As one who lived through those days with him, I can recall the trauma and special sense of responsibility he felt. His account of this period and of the sad deterioration of his relationship with his boss, Jim Webb, is both fair and generous. Those were not happy times, but they should not be allowed to overshadow the fact that in his seven years at NASA, Bob Seamans led the agency to its first successes and laid the groundwork for the great successes that came later.

Adicionalmente, se exploraron diferencias y similitudes espacio-temporales en la composición cualitativa de los ensambles de invertebrados. Se realizaron muestreos estacionales en cinco tramos del Bañado Carilauquen, desde la cabecera hasta la desembocadura. Se identificaron 47 taxa; 37 fueron insectos, principalmente Coleoptera, Diptera y Hemiptera, en ese orden. La composición de macroinvertebrados estuvo mejor condicionada por la variable espacial que por la temporal, en los extremos del gradiente espacial estudiado. Fueron detectados tres grupos faunísticos: cabecera, tramo medio y desembocadura. La mayor riqueza detectada en la cabecera se correspondió con los valores más bajos de conductividad del Bañado Carilauquen. La menor diversidad y la mayor diferencia en la composición faunística fueron observadas en la desembocadura (mayores niveles de conductividad. En el tramo medio, la riqueza fue mayor a la esperada según niveles de conductividad, debido posiblemente, a la presencia de especies transitorias.

    In southern South America the acquisition of high-quality Holocene paleoclimate data is a priority due to the paucity of complete, continuous and well dated records. Here we report preliminary results from a combined sedimentological and palynological study of an alluvial fan sequence and the laterally connected sedimentary deposits of the Vega de la Cueva profile at Agua Buena east of the Andes in central Argentina. The main geomorphological units of the area were identified and mapped based on satellite image analysis and multiple field surveys. The sedimentological and pollen results allowed us to reconstruct the development of some environments. The Agua Buena record corresponds to the distal facies of the Arroyo Bayo alluvial fan starting the aggradation process prior to ca. 4100 cal yr BP. The organic-rich levels found were formed during the development of wetlands (vegas) dominated by Cyperaceae, Juncaceae and Poaceae. These highly productive environments with almost permanent water saturation were important between 4100 and 2800 cal yr BP, indicating more stable conditions. After 2800 cal yr BP, the organic content was comparatively lower with increasing sedimentation rates that are indicative of higher fluvial discharges. This information is fundamental to interpret both the pollen and charcoal records of the area and to evaluate their representativeness and potential to reconstruct past local and/or regional vegetation.

    Radiolabeled somatostatin receptor (sst) agonists are integral to the diagnosis of gastroenteropancreatic neuroendocrine tumors (GEP-NETs), but detection rates, especially of liver metastases, remain disappointing even with PET/CT. 68 Ga-OPS202 ( 68 Ga-NODAGA-JR11), a novel radiolabeled sst antagonist with a high affinity for sst 2 , has the potential to perform better than sst agonists. Here we present the results of the Phase II component of a Phase I/II study, which evaluated the sensitivity of 68 Ga-OPS202 PET/CT compared with the reference compound, 68 Ga-DOTATOC (sst agonist). Methods: Patients received a single intravenous administration of 68 Ga-DOTATOC (15 µg peptide) and 68 Ga-OPS202 (15 µg peptide at visit 1; 50 µg peptide at visit 2) with an activity of 150 MBq. Whole-body PET/CT acquisitions were performed 1 h post injection on the same calibrated PET/CT scanner. Diagnostic efficacy measures were compared against contrast medium-enhanced CT or MRI as gold standard. Two independent blinded experts read the scans and both outcomes were combined for analysis. Results: Twelve consecutive patients with G1 or G2 GEP-NETs took part in this prospective study. Image contrast for matched malignant liver lesions was significantly higher for 68 Ga-OPS202 scans than for the 68 Ga-DOTATOC scan: median of the mean [interquartile] tumor-to-normal-liver SUV max ratios for 15 µg and 50 µg 68 Ga-OPS202 (5.3 [2.9 - 5.7] and 4.3 [3.4 - 6.3], respectively) were significantly higher than for 68 Ga-DOTATOC (1.9 [1.4 - 2.9]; P = 0.004 and P = 0.008, respectively). The higher tumor-to-background ratio of 68 Ga-OPS202 resulted not only in a higher detection rate of liver metastases, but also in a significantly higher lesion-based overall sensitivity with the antagonist than with 68 Ga-DOTATOC PET/CT: 94% and 88% for 50 µg and 15 µg 68 Ga-OPS202 and 59% for 15 µg 68 Ga-DOTATOC, respectively (pPET/CT and 68 Ga DOTATOC PET/CT were similar (approximately 98%).

    Full Text Available El depocentro triásico de Santa Clara, Cuenca Cuyana, se caracteriza por espesos depósitos generados en ambiente lacustre. Uno de ellos, con un registro de más de 345 m, corresponde a la Formación Mollar. El tramo inferior a medio está caracterizado por una monótona sucesión de lutitas bituminosas acumuladas por decantación suspensiva en el 'off shore' anóxico de un cuerpo lacustre hidrológicamente cerrado y que muestra alto contenido de materia orgánica amorfa de origen algal y de restos de plantas terrestres muy degradadas junto a sulfuros de hierro autígenos. Intercalan areniscas finas debidas a corrientes de turbidez diluidas y carbonatas estromatolíticos. En esta sucesión se definen ciclos granocrecientes de pequeña escala (PACs que se atribuyen a episodios de expansión-retracción lacustre controlados por cambios climáticos. Asociaciones de facies heterolíticas representan los depósitos de la transición entre los ambientes de 'nearshore' y 'offshore' lacustre. La sección superior de la Formación Mollar se compone de sucesiones pelíticas con profusa bioturbación que sugieren mayor oxigenación del sustrato y se asignan a ambiente de costa afuera de un sistema lacustre holomíctico hidrológicamente abierto. Intercalan areniscas producto de flujos hiperpicnales. Depósitos de areniscas con abundantes trazas fósiles y estructuras de olas y flujos unidireccionales, representan a sectores marginales del ambiente lacustre. Además de los ciclos de alta frecuencia, en la Formación Mollar se definen tres secuencias asimétricas de mayor escala atribuidas a episodios mayores de expansión-contracción lacustre debidos a la interacción entre factores climáticos y tectónicos. El diseño de superposición granocreciente de la Formación Mollar y la gradual transición a depósitos fluviales de la sobreyacente Formación Montaña refleja asimismo una constante reducción del espacio de acomodación sedimentaria en el depocentro de Santa Clara a medida que se produjo la acumulación de los depósitos estudiados.The Triassic Santa Clara depocenter, Cuyo Basin, is characterised by thick fine-grained deposits formed in lacustrine systems. One of them, represented by the Mollar Formation, exceeds the 345 m. The lower to middle section of this unit is dominated by a monotonous succession of black shales having a high content of amorphous organic matter produced by algae and highly degraded plant remains. These deposits were formed by suspensión fallout in the anoxic 'offshore' sector of a hydrologically closed lake. Thin and fine-grained turbiditic beds and stromatolitic carbonates are intercalated in the fine-grained succession. Small-scale coarsening-upward cycles (PACs are attributed to episodes of lake expansion-retraction driven by climate change. A facies association composed of an heterolithic package represents the deposits of the transition between 'nearshore' and 'offshore' settings. The upper section of the Mollar Formation essentially consists of bioturbated mudstones suggesting a greater oxygenation of the substrate. They are assigned to the 'offshore' environment of a holomictic hydrologically open lake system. Sporadic hyperpycnal flows are documented by intercalations of sandy turbidites. Bioturbated sandstone beds with primary structures indicative of both normal and storm wave action and unidirectional flows, represent the marginal deposits of the lacustrine system. In addition to the high-frequency cycles, three larger scale asymmetrical sequences are identified in the Mollar Formation. These sequences suggest episodes of major expansion-contraction of the lake system due to the interaction between climatic and tectonic factors. The overall shallowing up stacking pattern of the Mollar Formation and the gradual transition to fluvial deposits of the overlying Montaña Formation reflects a steady reduction of accommodation space in the Santa Clara depocenter during the accumulation of the studied succession.

Se concluyó que la diferencia significativa en el rendimiento atlético provincial se produjo al comparar la década del 80 con los años 2000 y 2001. Por lo tanto se rechazó la Hi y se aceptó la H alternativa. Se midieron las variables que influyeron sobre la evolución de este potencial, concluyendo que su disminución tiene relación con el estado que presentan las pistas en uso, insuficientes elementos atléticos, escasa cantidad de profesores especialistas, déficit en la administración de recursos físicos y humanos de los responsables del atletismo federado y falta de proyectos que canalicen la cantidad de jóvenes que compiten en instancias escolares y no ingresan al circuito federado.-------------------------------------------------------------------------Descriptive exploratory study with non experimental longitudinal retrospective design that analyzes the changes in the athletic potential of Mendoza’s population from 1973 to 2001.

The conclusion was that the significant difference in provincial athletic performance was obtained when comparing the decade of the 80s with the years 2000 and 2001. Thus, the Hi was rejected and the alternative H was accepted. The variables that influenced the evolution of this potential were measured, concluding that its decline is related to the state of the tracks in use, insufficient athletic items, lack of specialist teachers, a deficit in the administration of physical and human resources by those responsible for the athletics federation and a lack of projects to channel the number of young people competing at school level that fail to enter the federate circuit.

    Full Text Available La producción de vid es la fuente económica agroindustrial principal en Cuyo (28°S-36°S / 65°W-70°W, siendo la región de más elevado desarrollo vitivinícola del país. Uno de los factores climáticos de mayor impacto en la producción de vid es la destrucción del cultivo por granizo, como resultado de la convección severa desarrollada en época estival. La violencia con que se desarrollan las tormentas estivales de granizo genera un impacto importante en el rendimiento de los viñedos afectados, logrando la disminución parcial o total de parcelas enteras. Durante el período 1979-2008, la precipitación de verano presenta fluctuaciones de la escala 7-8 años al igual que la producción total de vid y ambas se encuentran inversamente correlacionadas intradecádicamente. Asimismo, veranos húmedos (secos pueden presentar mayor (menor probabilidad de ocurrencia de daños por granizo en la temporada actual que se pueden asociar a menor (mayor producción de vid en la temporada del año siguiente debido a cambios en la disponibilidad de yemas fértiles. También una fracción de la variación de la producción de vid en el verano actual puede estar asociada a cambios en la precipitación de ese verano por daño directo (intensidad de la precipitación o indirecto (anegamiento relativamente prolongado ya que la desfoliación y asfixia radicular parecen afectar el rendimiento de las plantas. La clara dependencia climática de cultivo muestra que la producción total anual de vid está modulada por las variaciones de la precipitación en escalas decádicas, la cual está vinculada a factores de escala global del sistema climático. Se derivan potenciales resultados para el pronóstico de la producción de vid bajo futuros escenarios de cambio climático para la región.The grape production is the main economic source in the agro-industry of Cuyo (28°S-36°S / 65°W- 70°W, becoming the most developed region for wine production in Argentina. One of the climate factors of major impact on the grapevine production is the destruction of the vineyards due to graze, as a result of summer deep convection. The strong graze storms affect the vineyard yields, provoking a partial or total deterioration of entire parcels. In the analyzed period 1979-2008 both, the summer precipitation and the grape production show significant oscillation at the scale 6-8 years being inversely correlated within the decade scale. Likewise, a wet (dry summer can have more (less probability of occurrence of graze harm during the actual summer being associated with lower (higher grapevine production in the following year campaign due to changes in the availability of grape buds. Also a fraction of the grape production variation in the actual summer can be associated with changes in the precipitation of the same summer due to direct harm (precipitation intensity or indirectly due to relatively prolonged floods. The clear climate dependence of the grape farming shows that the annual grapevine production is modulated by decadal 2 precipitation variations, which are linked to global features of the climate system. Potential results for the grapevine production forecast are derived under future climate change scenarios in the region.

    Based on gravimetric and magnetic data, together with isostatic and elastic thickness analyses, we modeled the crustal structure of the area. Information obtained has allowed us to understand the crust where the SRB and the Payenia volcanic province are located. Bouguer anomalies indicate that the SRB presents higher densities to the North of Cerro Nevado and Moho calculations suggest depths for this block between 40 and 50 km. Determinations of elastic thickness would indicate that the crust supporting the San Rafael Block presents values of approximately 10 km, being enough to support the block loading. However, in the Payenia region, elastic thickness values are close to zero due to the regional temperature increase.

  6. Magneto stratigraphy and 40Ar - 39Ar dating of the neogene synorogenic strata of Northern Mendoza, Argentina: Tectonic implications

    International Nuclear Information System (INIS)

    Irigoyen, Maria V.; Ramos, Victor A.; Brown, Richard L.

    1998-01-01

    Full text: At the southernmost extension of the Pre cordillera fold-and-thrust belt, 33 S latitude, about 4000 m of Cenozoic foreland-basin strata record the eastern migration of the Andean thrust from since the Neogene. These deposits accumulated in response to exhumation and deformation of the western Principal and Frontal cordilleras. The detrial clastic strata cropping out in the La Pilona-Tupungato region, comprise five formation units that record fluvial, eolian and alluvial deposition in an arid setting. To link the sequence of deformational events in the western mountain belts with the sedimentary record, all units except the youngest have been dated using magnetic polarity stratigraphy calibrated with 40 Ar - 39 Ar dates on inter bedded tephras. A precise chronology of these deposits in conjunction with a multiple data set that include rates of sedimentation in the foreland, a provenance study on these rocks, and facies and textural patterns, provide the basis for documenting details of tectonic activity, volcanism and deposition. The oldest Marinio Fm., whose deposition spans ∼15.7-12.2 Ma, is interpreted to record two phases of thrusting in the Principal Cordillera (Irigoyen 1997). The earlier phase is tied to deformation of the Mesozoic andesitic volcanic complex cropping out in the western part of the Aconcagua fold-and-thrust belt. The second phase of thrusting is linked with deformation of the Mesozoic marine sequences of the central part of the Aconcagua fold-and-thrust belt. The overlying La Pilona Fm., whose deposition spans ∼11.7-9.0 Ma, is thought to record the initiation of exhumation of the Frontal Cordillera. Provenance and paleocurrent data are consistent with clast derivation from northwestern highland sources (i.e., cordon and cuchillas del Tigre) which provided volcanic detritus from the Choiyoi Group and low-grade metamorphic and sedimentary rocks of lower Paleozoic age. Exhumation and displacement of the Frontal Cordillera overlapped in time with deformation in the Principal Cordillera in which the latest phase of deformation is known to occur at ∼8.0 Ma (e.g., Ramos 1996). The extensive ash-rich unit, the 8.9-8.7 Ma Tobas Angostura Fm., is correlated with the latest extrusive episode that included pyroclastic eruptions in the Principal Cordillera. An unconformity separates the Rio de los Pozos Fm., probably at least as young as ∼7.2 Ma, from the youngest Mogotes Fm. This unit, whose deposition spans ∼3.1 Ma, includes the large boulder conglomerates that today lie at the foot of the cordon del Plata immediately to the west of the study site. Therefore, deposition of this unit is linked with deformation in the flanking Frontal Cordillera. Neogene strata are deformed into fault-propagation folds and emergent east-verging thrusts which, in some cases, also display a sinistral strike-slip component. The timing of deformation of the Tertiary sequence is constrained by an ash-tuff layer un conformably overlying these deposits and dated at 0.39 ± 0.03 Ma. (author)

  7. Assessment of soil erosion vulnerability in the heavily populated and ecologically fragile communities in Motozintla de Mendoza, Chiapas, Mexico

    Science.gov (United States)

    González-Morales, Selene B.; Mayer, Alex; Ramírez-Marcial, Neptalí

    2018-06-01

    Variability in physical rates and local knowledge of soil erosion was assessed across six rural communities in the Sierra Madre del Sur, Chiapas, Mexico. The average erosion rate estimated using the RUSLE model is 274 t ha-1 yr-1, with the estimated erosion rates ranging from 28 to 717 t ha-1 yr-1. These very high erosion rates are associated with high rainfall erosivity (17 000 MJ mm ha-1 h-1 yr-1) and steep slopes (mean slope = 67 %). Many of the highest soil erosion rates are found in communities that are dominated by forestland, but where most of the tree cover has been removed. Conversely, lower erosion rates are often found where corn is cultivated for most of the year. According to the results of the soil erosion KAP (knowledge, attitude and practices) survey, awareness of the concept of soil erosion was reasonably high in all of the communities, but awareness of the causes of erosion was considerably lower. More than half of respondents believed that reforestation is a viable option for reducing soil erosion, but only a third of respondents were currently implementing reforestation practices. Another third of the respondents indicated that they were not following any soil conservation practices. Respondents indicated that adoption of government reforestation efforts have been hindered by the need to clear their land to sell forest products or cultivate corn. Respondents also mentioned the difficulties involved with obtaining favorable tree stocks for reforestation. The KAP results were used to assess the overall level of motivation to solve soil erosion problems by compiling negative responses. The relationship between the magnitude of the soil erosion problem and the capacity to reduce soil erosion is inconsistent across the communities. One community, Barrio Vicente Guerrero, had the highest average negative response rate and the second highest soil erosion rate, indicating that this community is particularly vulnerable.

  9. Friendship 7 the epic orbital flight of John H. Glenn, Jr.

    CERN Document Server

    Burgess, Colin

    2015-01-01

    In this spellbinding account of an historic but troubled orbital mission, noted space historian Colin Burgess takes us back to an electrifying time in American history, when intrepid pioneers were launched atop notoriously unreliable rockets at the very dawn of human space exploration.   A nation proudly and collectively came to a standstill on the day this mission flew; a day that will be forever enshrined in American spaceflight history. On the morning of February 20, 1962, following months of frustrating delays, a Marine Corps war hero and test pilot named John Glenn finally blazed a path into orbit aboard a compact capsule named Friendship 7.   The book’s tension-filled narrative faithfully unfolds through contemporary reports and the personal recollections of astronaut John Glenn, along with those closest to the Friendship 7 story, revealing previously unknown facts behind one of America’s most ambitious and memorable pioneering space missions.

    This year was the third in which LANSCE ran a formal user program. A call for proposals was issued before the scheduled run cycles, and experiment proposals were submitted by scientists from universities, industry, and other research facilities around the world. An external program advisory committee, which LANSCE shares with the Intense Pulsed Neutron Source (IPNS), Argonne National Laboratory examined the proposals and made recommendations. At LANSCE, neutrons are produced by spallation when a pulsed, 800-MeV proton beam impinges on a tungsten target. The proton pulses are provided by the Clinton P. Anderson Meson Physics Facility (LAMPF) accelerator and an associated Proton Storage Ring (PSR), which can alter the intensity, time structure, and repetition rate of the pulses. The LAMPF protons of Line D are shared between the LANSCE target and the Weapons Neutron Research facility, which results in LANSCE spectrometers being available to external users for unclassified research about 80% of each six-month LAMPF run cycle. Measurements of interest to the Los Alamos National Laboratory may also be performed and may occupy up to an additional 20% of the available beam time. These experiments are reviewed by an internal program advisory committee. One hundred thirty-four proposals were submitted for unclassified research and twelve proposals for research of a programmatic nature to the Laboratory. Our definition of beam availability is when the proton current from the PSR exceeds 50% of the planned value. The PSR ran at 65{mu}A current (average) at 20 Hz for most of 1990. All of the scheduled experiments were performed and experiments in support of the LANSCE research program were accomplished during the discretionary periods.

    Nuclear weapons make possible the ultimate epidemic. Since their use would lead to human and material damage orders of magnitude more extensive than anything ever known, and since the medical community would be impotent to respond in any meaningful way, all efforts must be directed to the prevention of nuclear war. By ensuring that the medical realities are known to decision-makers and the people of the world, the medical community can help focus attention on the critical need for an effective prescription for prevention and thereby can contribute in an important fashion to national security

    Trapa, Peter

    2015-01-01

    Over the last forty years, David Vogan has left an indelible imprint on the representation theory of reductive groups.  His groundbreaking ideas have lead to deep advances in the theory of real and p-adic groups, and have forged lasting connections with other subjects, including number theory, automorphic forms, algebraic geometry, and combinatorics. Representations of Reductive Groups is an outgrowth of the conference of the same name, dedicated to David Vogan on his 60th birthday, which took place at MIT on May 19-23, 2014.  This volume highlights the depth and breadth of Vogan's influence over the subjects mentioned above, and point to many exciting new directions that remain to be explored.  Notably, the first article by McGovern and Trapa offers an overview of Vogan's body of work, placing his ideas in a historical context.

    Fry-Revere, Sigrid

    1992-01-01

    Although Engelhardt's The Foundations of Bioethics is an impressive work, it is plagued by problems of justification, conceptual confusion, and inconsistencies....A libertarian theory can arrive at the same basic requirements of mutual respect, autonomy, nonuse of force, and tolerance for a wide range of diverse life styles without relying on a lowest-common-denominator principle and without depriving fetuses, infants, and the mentally retarded of their status as persons. This can be done by taking a deontological approach to libertarian theory that denies that all moral beliefs are worthy of respect. Some beliefs, such as Engelhardt's belief that fetuses, infants, and the mentally retarded are nonpersons, simply fall beneath the floor of acceptable moral alternatives, even in a libertarian society, because such beliefs are based on a misunderstanding of personhood and violate the principle of mutual respect.

    Full Text Available The determination of static and/or variable stress, in case of complex shaped welded structures is hard to achieve. One solution, though, is the use of finite element method, implemented by means of various specialized software. Nowadays, this method has become very popular due to its high precision of data obtained through both research and finite element analysis. Hence, the present paper deals with the modelling of the pull-out behaviour of concave and convex welded joints through finite element method.

    International Nuclear Information System (INIS)

    1981-01-01

    Operational definition of J concept is first examined. Then it is shown that conventional methods of experimental determination of J values are based on the following assumption: if the load-deflexion curve is known for one value of the crack length it is possible to know the load-deflexion curve for any value of the crack length. This assumption is generalized with the help of scale functions and formula giving J are deduced. Attention is given to the effect of crack propagation on J values. The same assumption is used to extract the crack length from the load-deflexion curve. As the real crack lengths are known before propagation occurs and at the end of the test, it is possible to achieve a good calibration of the material characteristic [fr

    2004-09-01

    This paper is a critique of certain moral perspectives that are found in the second edition of Engelhardt's Foundation of Bioethics. These views are spelled out in explicit detail in his second edition, and follow on the heels of a profound religious conversion. Engelhardt is an eminent bioethicist with strong religious convictions that overlay much of his writing. The author wishes to question some of the conclusions that Engelhardt reaches as they touch upon moral frameworks, pluralism, and a 'secular' bioethics.

    Nick Timbers took over as the first Transition Manager of the US Enrichment Corporation upon its founding last July 1st. Although USEC is not involved in negotiating the HEU deal, the fledgling company will be in charge of actually buying and selling the resulting LEU. Whenever the deal is finally signed. After the politics and haggling are over, it will be up to Nick Timbers to make the deal work on the global uranium market. The view from USEC is resolute. No matter what shape the final HEU deal takes, Nick Timbers promises that USEC will remain a competitive supplier of enrichment services. Timbers pledges that any extra costs associated with the HEU deal will not be passed on to customers. He took time out from his recent busy schedule to share his thoughts on HEU and its aftermath

    Lejaren Hiller (1924-1994) was trained in chemistry but maintained a lifelong love of music. Like Alexander Borodin, the Russian chemist-composer, but eventually dedicated his career solely to music. His early work on the chemistry of polymers with Fred Wall at the University of Illinois introduced him to the Illiac computer, with which he did Monte Carlo calculations of polymer conformations. He promptly collaborated with Leonard Isaacson, a graduate student also associated with the Wall group, to teach the Illiac to compose music. Using a modified Monte Carlo technique to select the notes and other aspects of the music, they applied increasingly complex rules to define what constituted acceptable music. The result was their String Quartet #4, produced in 1957, often called the Illiac Suite. It is generally acknowledged as the first piece of music composed by a computer. Hiller remained a pioneer in the field of copmuter composition during his distinguished career at the University of Illinois and the State University of New York at Buffalo. This paper traces Hiller's careers in chemistry and music and examines the connections between the two.

    2016-01-01

    This book celebrates the final spaceflight in the Mercury series, flown by NASA astronaut Gordon Cooper, who led an adventurous life in the cockpit of airplanes and spacecraft alike, and on his Mercury mission he became the last American ever to rocket into space alone. He flew in the Mercury and Gemini programs and served as head of flight crew operations in both the Apollo and Skylab programs. His final Mercury mission closed out a pivotal chapter in American spaceflight. Based on extensive research and first-person interviews, this is a complete history of the Faith 7 flight and its astronaut. Cooper later gained notoriety following the release of the movie, The Right Stuff, in which he was depicted by Dennis Quaid, but Burgess discovers there was even more drama to his story. This recounting of the final Mercury 7 flight completes Burgess's investigation of the early spaceflight program in thrilling fashion.

    Scinax melanodactylus is a small treefrog distributed within the Tropical Atlantic morphoclimatic domain (see Ab'Sáber 1977 for South American morphoclimatic domains), from northern Espírito Santo state to Sergipe state in Brazil (Lourenço et al. 2014). The species is usually found inhabiting herbaceous and shrubby xerophytic vegetation (e.g. terrestrial tank-bromeliads) from sandy plains of beach ridges known in Brazil as Restingas (see Rocha et al. 2007 for a Restinga definition), and also the edge of forest areas with temporary ponds and/or permanent lakes and streams near these environments (Bastazini et al. 2007, as Scinax agilis; Lourenço et al. 2014). Scinax melanodactylus is currently placed in the S. catharinae species group (Lourenço et al. 2014), which in turn is included in the S. catharinae clade (sensu Faivovich et al. 2005). The S. catharinae clade is currently comprised of 46 species, 33 placed in the catharinae group and 13 in the perpusillus group (Faivovich et al. 2010, Silva & Alves-da-Silva 2011, Lourenço et al. 2014, Frost 2015). From these, 32 species have tadpoles with external morphology and oral disc formerly described. Here, we describe the external morphology, oral disc and color patterns of the previously unknown tadpole of S. melanodactylus.

En este marco, el presente artículo plantea la reflexión sobre cuál es el límite que existe entre los nuevos elementos en los paisajes rurales producto del proceso evolutivo de adaptación a los cambios económicos, técnicos y sociales de la época y la banalización del paisaje; y también, cómo poder detectar los elementos que están transformando el carácter del paisaje al punto de la banalización en un marco paisajístico dinámico y de heterogeneidad. Ante ello, se sostiene como hipótesis que la dimensión histórica del paisaje permite detectar y enfrentar a la banalización del mismo, ya que la relación conceptual dimensión histórica versus banalización del paisaje puede ser empleada como una herramienta para su análisis.

    In southern South America the acquisition of high-quality Holocene paleoclimate data is a priority due to the paucity of complete, continuous and well dated records. Here we report preliminary results from a combined sedimentological and palynological study of an alluvial fan sequence and the laterally connected sedimentary deposits of the Vega de la Cueva profile at Agua Buena east of the Andes in central Argentina. The main geomorphological units of the area were identified and mapped based on satellite image analysis and multiple field surveys. The sedimentological and pollen results allowed us to reconstruct the development of some environments. The Agua Buena record corresponds to the distal facies of the Arroyo Bayo alluvial fan starting the aggradation process prior to ca. 4100 cal yr BP. The organic-rich levels found were formed during the development of wetlands (vegas) dominated by Cyperaceae, Juncaceae and Poaceae. These highly productive environments with almost permanent water saturation were important between 4100 and 2800 cal yr BP, indicating more stable conditions. After 2800 cal yr BP, the organic content was comparatively lower with increasing sedimentation rates that are indicative of higher fluvial discharges. This information is fundamental to interpret both the pollen and charcoal records of the area and to evaluate their representativeness and potential to reconstruct past local and/or regional vegetation.

    Full Text Available The most recent massage therapy (MT study by Hernandez-Reif et al. displays flaws persistent in this area of research that are attributable to MT researchers’ frequent mistake of using within-group analyses of dependent variables in studies that are purported to be randomized control trials. This practise violates the logic of using randomization to create treatment and control groups, and thereby fails to control for the validity threats of spontaneous remission, placebo effects, and statistical regression. The result is that a clear understanding of what MT can and cannot do is seriously hampered.

    Full Text Available In early 1917, a company that gathered all of Mendoza’s wine producers was founded. This was the last anti-cyclical strategy promoted by the State with the goal of dealing with a long lasting economical crisis. It aimed to set wine and grape prices in a monopolistic fashion, and to establish wine marketing quotas. The limited amount of bibliography on this topic is what motivated this study, based on 3 aspects: how it was created, who it benefitted and how it was dissolved. Lack of official documentation forced its story to be rebuilt with information gathered from newspapers and public and private memoirs. It was concluded that the ideas this experiment was based on were misguided, since wine is a dispensable and replaceable asset. It was also concluded that it benefitted wine growers and that its dissolution process was longer and more complex than it foreseen.

El objetivo de este artículo es analizar, en escolares de 4 y 5 años, la relación entre el nivel educativo y socioeconómico del hogar con habilidades lingüísticas precursoras de la lectura. Esta es una investigación de carácter cuantitativo y de profundidad comparativa. Se evaluaron 120 niños y niñas de salas de 4 y 5 años de Jardín de Infantes de escuelas urbanas (n= 60 y urbano-marginales (n= 60. El nivel socioeconómico del hogar y educativo de los padres se calculó a partir de datos de los registros escolares. En los niños y niñas se evaluó el nivel de vocabulario, conocimiento del nombre y sonido de la letra y conciencia fonológica. Se observó un efecto significativo de la zona sobre el nivel educativo de los padres y el socioeconómico. Se obtuvieron correlaciones positivas del nivel socioeconómico y educativo con el conocimiento del nombre y sonido de la letra. Ambas variables contextuales explicaron parte de la varianza en el conocimiento del nombre y sonido de las letras en niños y niñas de 4 años únicamente: 6% y 13% respectivamente. Los resultados sugieren que las variables contextuales influyen en el conocimiento alfabético pre-escolar que presentan los niños y las niñas y que la intervención pedagógica recibida en la escuela promueve el desarrollo de habilidades lingüísticas. Frente a contextos socioeconómicos heterogéneos, la educación escolar es una variable protectora que regula las desigualdades de orden social promoviendo el desarrollo de habilidades lingüísticas precursoras de la lectura al inicio de la escolaridad.

    Full Text Available El artículo traza un panorama de los cambios verificados en la vitivinicultura de la gran región productora de vinos de la Argentina durante los últimos 35 años, con especial mención a las innovaciones institucionales, impresariales, técnicas y laborales registradas. La mención de algunos antecedentes sobre un siglo de trayectoria vitivinícola permiten apreciar con mayor claridad las transformaciones recientes de la agroindustria y el papel de los diferentes actores sociales involucrados. Particularmente destacados son los cambios operados por el Estado, que actuó como promotor, regulador y empresario, desregulador y, nuevamente, promotor, pero siempre articulado con los sectores empresarios. El acelerado proceso de cambios desde la década de 1990 supuso una reorientación de la actividad, otrora concentrada en el mercado interno, para posicionar a la región en lugares de creciente relevancia en el mercado internacional de vinos finos. El análisis a escala regional se complementa, finalmente, con los cambios que se producen a escala de empresas y las estrategias que desarrollan para crecer y competir.

    Full Text Available Dermatobia hominis (Linnaeus, 1781 midgut is internally lined by an epithelium of polytenic cells, some low others prismatic with well developed brush border. Their apical portion are enlarged by secretory vesicles, forming button-like structures that are pinched off to the lumen, some accompained by the nucleus characterizing apocrine and holocrine secretions. This epithelium is gradually renewed by small, non polytenic regenerative cells, found scattered at its basal portion. At the end of the third instar the metamorphosis begins. The epithelial cells present signs of degeneration and at the first day of pupation the regenerative cells increase in number. By the 5th day of pupation these regenerative cells, besides being increased in number, differentiate themselves into two layers: one similar to the dense conective tissue that sustainning the larval epithelium is pinched off to the midgut lumen forming the "yellow bodies"; the other, develops right under it as the imaginal epitelium. The disorganized muscles bundles of the midgut wall, are invaded by phagocytes. At the end of pupation the midgut has a low prismatic epithelium with brush-border. In the adult, the torax portion of the midgut has prismatic homogeneously basophilic epithelium while in the abdominal portion the epithelium is made of high prismatic cells full of small vacuoles. The larval midgut epithelium suffers programmed cell death non compatible with apoptose. During the metamorphosis the midgut lenght diminishes from 31mm in the larva to 14mm in the adult.

    Aiming at achieving a maglev Shinkansen that links Tokyo with Osaka at a speed of 500 km/h, an experimental maglev line is being constructed in Yamanashi Prefecture. This paper explains a train control system as the main subject. The system mounts superconductive magnets directly on bogies to propel a train using actions of moving magnet fields generated from propulsion coils paved on ground. Because of its mechanism to levitate and guide the train using induction coils superposed on the propulsion coils, no special control device is required for the levitation and guidance. This is a difference from a normal conduction magnet levitation system. Its speed control also differs from the conventional railway systems. It uses a ground primary control system that controls supply currents from substations on the ground, including braking control. One substation controls one train only. Automatic control is made on all controls related to travelling, including a control from train movement start to stops at predetermined positions, scheduled-time operation control, and jerk control. The construction of the experimental line is under steady progress. 5 figs.

  20. George E. Valley, Jr. Prize Talk: Quantum Frustrated Magnetism and its Expression in the Ground State Selection of Pyrochlore Magnets

    Science.gov (United States)

    Ross, Kate

    In the search for novel quantum states of matter, such as highly entangled Quantum Spin Liquids, ``geometrically frustrated'' magnetic lattices are essential for suppressing conventional magnetic order. In three dimensions, the pyrochlore lattice is the canonical frustrated geometry. Magnetic materials with pyrochlore structures have the potential to realize unusual phases such as ``quantum spin ice'', which is predicted to host emergent magnetic monopoles, electrons, and photons as its fundamental excitations. Even in pyrochlores that form long range ordered phases, this often occurs through unusual routes such as ``order by disorder'', in which the fluctuation spectrum dictates the preferred ordered state. The rare earth-based pyrochlore series R2Ti2O7 provides a fascinating variety of magnetic ground states. I will introduce the general anisotropic interaction Hamiltonian that has been successfully used to describe several materials in this series. Using inelastic neutron scattering, the relevant anisotropic interaction strengths can be extracted quantitatively. I will discuss this approach, and its application to two rare earth pyrochlore materials, Er2Ti2O7 and Yb2Ti<2O7, whose ground state properties have long been enigmatic. From these studies, ErTi2O7 and Yb2Ti2O7 have been suggested to be realizations of "quantum order by disorder" and "quantum spin ice", respectively. This research was supported by NSERC of Canada and the National Science Foundation.

We utilized the particle accelerators at the Fermi National Accelerator Laboratory (Fermilab) in Illinois, the Stanford Linear Accelerator Center (SLAC) in California, and the European Center for Nuclear Research (CERN) in Switzerland. Mishra, Rosenfeld, and Petti worked predominantly on neutrino experiments. Experiments conducted in the last fifteen years that used cosmic rays and the core of the sun as a source of neutrinos showed conclusively that, contrary to the former conventional wisdom, the "flavor" of a neutrino is not immutable. A neutrino of flavor "e," "mu," or "tau," as determined from its provenance, may swap its identity with one of the other flavors -- in our jargon, they "oscillate." The oscillation phenomenon is extraordinarily difficult to study because neutrino interactions with our instruments are exceedingly rare -- they travel through the earth mostly unimpeded -- and because they must travel great distances before a substantial proportion have made the identity swap. Three of the experiments that we worked on, MINOS, NOvA, and LBNE utilize a beam of neutrinos from an accelerator at Fermilab to determine the parameters governing the oscillation. Two other experiments that we worked on, NOMAD and MIPP, provide measurements supportive of the oscillation experiments. Good measurements of the neutrino oscillation parameters may constitute a "low energy window" on related phenomena that are otherwise unobservable because they would occur only at energies way above the reach of conceivable accelerators.

  7. «Huarpes no tan huarpes» y «hombres modernos»: interpelaciones étnicas y disputas por las últimas tierras irrigadas en Mendoza (Argentina

    Directory of Open Access Journals (Sweden)

    Leticia Saldi

    2015-05-01

    Full Text Available A través de un estudio etnográfico en la periferia del oasis de riego más importante del centro-oeste argentino, se analiza la intervención de persistentes representaciones étnico-raciales y ambientales en la delimitación de áreas irrigadas y de grupos sociales que ostentan la tenencia del agua y la tierra. Los grupos situados a uno y otro lado de los últimos canales de riego son interpelados desde paradigmas modernistas que vinculan a la tenencia del agua, la propiedad privada y la producción vitivinícola con la herencia europea y la idea de progreso, mientras que lo no irrigado, la tenencia comunitaria de la tierra y el pastoreo trashumante se asocia a la descendencia indígena huarpe y a la idea de atraso o involución. Debido a la presencia de dos espacios y grupos socio-culturales supuestamente autónomos, opuestos y separados por los últimos canales de riego es que se los conceptualiza como frontera hídrica. Esta, a pesar de ser considerada como natural y fija, es por el contrario artificial y dinámica, producto de luchas sociales y simbólicas por el agua y por la obtención de legitimidad como grupo socio-cultural capaz de obtenerla y controlarla. Asimismo se resaltan la presencia no solo de actores liminales, ni huarpes ni de origen europeo, sino también de alianzas que pueden llevar a la reconfiguración de espacios irrigados y de grupos socioculturales capaces de dar batalla en las disputas por los recursos naturales.

    2016-06-01

    Full Text Available El presente trabajo estudia el comportamiento térmico y energético de edificios residenciales en altura, en el contexto particular de una “ciudad-oasis”. Se plantea como objetivo la definición de sistemas de control solar adecuados en la envolvente para cada tipología material de edificio -másica y liviana- y para cada estrato en altura de las viviendas: debajo y sobre de la copa de los árboles. El monitoreo de viviendas en uso permite validar modelos geométricos (software Energy Plus y simular propuestas de aplicación de elementos de protección solar. Se analizan los ahorros en los consumos para enfriamiento en departamentos en niveles bajos, medios y altos. Los resultados muestran que en el edificio másico, en las viviendas ubicadas debajo de la copa de los árboles, es posible anular las cargas energéticas para enfriamiento mediante el uso de elementos exteriores de protección solar. Mientras que en las viviendas sobre la copa de los árboles, los ahorros energéticos se encuentran entre el 32% y 42%. En el edificio liviano, la aplicación de sistemas de control en departamentos bajo la copa de los árboles alcanza ahorros del orden del 53% y en las viviendas sobre la copa, las reducciones energéticas se encuentran entre el 46% y 54%. Las dimensiones adecuadas de tales elementos pueden generar propuestas posibles de ser transferidas a las normativas locales de edificación.

    Full Text Available El incremento de vegetación urbana es una estrategia de mitigación de la isla de calor reconocida a nivel mundial. Este trabajo evalúa cómo el balance energético de un cañón urbano es afectado por combinaciones de la morfología de la trama urbana, la fisonomía forestal y la densidad de edificación del entorno construido. Se monitoreó el comportamiento térmico de verano de 16 cañones urbanos de 16, 20 y 30 m de ancho, localizados en alta y baja densidad de edificación, y forestados con tres especies predominantes en la ciudad, así como también uno de los casos sin forestar. Para evaluar el grado de habitabilidad de los espacios abiertos se utilizó el balance energético COMFA. Los resultados muestran que la adecuada selección de la especie forestal es clave para maximizar la eficiencia energética y la habitabilidad de los espacios urbanos en las áreas de baja densidad de edificación presentes en la ciudad.

    2016-12-01

    Full Text Available La trayectoria de José Pescara, labrador y hacendado mendocino que logró no sólo edificar un amplio patrimonio familiar sino ejercer una serie de funciones en la justicia menor de la campaña mendocina, sirve de mirador para reflexionar sobre, al menos, dos cuestiones. Por una parte, acerca de las diversas formas a través de las cuales ciertos advenedizos lograron integrarse exitosamente en las élites tardocoloniales y revolucionarias rioplatenses. Por otra, respecto de la experiencia de la justicia de proximidad, a la vez como reconocimiento de prominencia y recurso para la acumulación de capital simbólico. La hipótesis de trabajo sostiene que las responsabilidades judiciales ejercidas por Pescara dieron cuenta de su incorporación en una trama de relaciones privilegiadas concentradas en el cuerpo de vecinos representados por el cabildo, pero también de que la justicia de proximidad ocupó un rol relevante en su propia estrategia de reproducción de su patrimonio familiar.

    Full Text Available En Argentina, las dificultades en la adquisición de la lectura se originan en diferencias lingüísticas asociadas al nivel sociocultural donde se desarrollan los niños. El objetivo de este artículo es analizar, en escolares de 4 y 5 años, la relación entre el nivel educativo y socioeconómico del hogar con habilidades lingüísticas precursoras de la lectura. Esta es una investigación de carácter cuantitativo y de profundidad comparativa. Se evaluaron 120 niños y niñas de salas de 4 y 5 años de Jardín de Infantes de escuelas urbanas (n= 60 y urbano-marginales (n= 60. El nivel socioeconómico del hogar y educativo de los padres se calculó a partir de datos de los registros escolares. En los niños y niñas se evaluó el nivel de vocabulario, conocimiento del nombre y sonido de la letra y conciencia fonológica. Se observó un efecto significativo de la zona sobre el nivel educativo de los padres y el socioeconómico. Se obtuvieron correlaciones positivas del nivel socioeconómico y educativo con el conocimiento del nombre y sonido de la letra. Ambas variables contextuales explicaron parte de la varianza en el conocimiento del nombre y sonido de las letras en niños y niñas de 4 años únicamente: 6% y 13% respectivamente. Los resultados sugieren que las variables contextuales influyen en el conocimiento alfabético pre-escolar que presentan los niños y las niñas y que la intervención pedagógica recibida en la escuela promueve el desarrollo de habilidades lingüísticas. Frente a contextos socioeconómicos heterogéneos, la educación escolar es una variable protectora que regula las desigualdades de orden social promoviendo el desarrollo de habilidades lingüísticas precursoras de la lectura al inicio de la escolaridad.

    2004-01-01

    The above paper [Corros. Sci. 45 (2003) 2497] declares a general approach to describing stress corrosion cracking (SCC) mechanism and despite of the criticism of the so-called 'surface mobility mechanism' (SMM) e.g., [Corros. Sci. 36 (1994) 669, Corros. Sci. 45 (2003) 2105]. The paper [Corros. Sci. 45 (2003) 2497] demonstrates inner contradictions and mutually excluding statements of SMM when fitted calculated and measured values of crack propagation rate. As shown in these Comments, the crack propagation rate calculated using SMM is only the Nabarro-Herring creep deformation rate, which can never be numerically equal to the crack propagation rate. Thus, tests undertaken by the author of SMM cannot be accepted as experimental evidence of the SMM

    2012-03-01

    Rahm sought to illuminate how children and youth make meaning of science in three out-of-school time programs, and the identity work that is done through the trajectory of their youth toward their young adulthood. Through using multisited ethnography, she asserts that we can learn more about what the youth say about their science learning and science literacy development in these programs. She has revealed through her rich data the potential value of multisited ethnography for science education research. A similar theme of insider/outsider status to science emerged in each of the three sites. The nature of the data collected in Rahm's multisited ethnography allowed for the unveiling of the similarities in this theme, but also made evident the nuanced ways that this theme presented itself differently across the three sites. The additional potential came through in the varied data Rahm could have delved into and did not. A unique characteristic of ethnographic research, that is not necessarily present in other research methods, is that a wide array of varied data is collected. An analysis of documents, images, and observational field notes, which go beyond interview data, may provide deeper understandings previously untouched in science education.

  20. Database of the Geologic Map of North America - Adapted from the Map by J.C. Reed, Jr. and others (2005)

    Science.gov (United States)

    Garrity, Christopher P.; Soller, David R.

    2009-01-01

    The Geological Society of America's (GSA) Geologic Map of North America (Reed and others, 2005; 1:5,000,000) shows the geology of a significantly large area of the Earth, centered on North and Central America and including the submarine geology of parts of the Atlantic and Pacific Oceans. This map is now converted to a Geographic Information System (GIS) database that contains all geologic and base-map information shown on the two printed map sheets and the accompanying explanation sheet. We anticipate this map database will be revised at some unspecified time in the future, likely through the actions of a steering committee managed by the Geological Society of America (GSA) and staffed by scientists from agencies including, but not limited to, those responsible for the original map compilation (U.S. Geological Survey, Geological Survey of Canada, and Woods Hole Oceanographic Institute). Regarding the use of this product, as noted by the map's compilers: 'The Geologic Map of North America is an essential educational tool for teaching the geology of North America to university students and for the continuing education of professional geologists in North America and elsewhere. In addition, simplified maps derived from the Geologic Map of North America are useful for enlightening younger students and the general public about the geology of the continent.' With publication of this database, the preparation of any type of simplified map is made significantly easier. More important perhaps, the database provides a more accessible means to explore the map information and to compare and analyze it in conjunction with other types of information (for example, land use, soils, biology) to better understand the complex interrelations among factors that affect Earth resources, hazards, ecosystems, and climate.

  1. XRF analysis to identify historical photographic processes: The case of some Interguglielmi Jr.’s images from the Palermo Municipal Archive

    2017-01-01

    In the early period, even though professional photographers worked with similar techniques and products, their artistic and commercial aims determined different choices and led them to follow different, often personal, recipes. For this reason, identification of the techniques through date and name of the photographer or through some visual features like colour, tonality and surface of the image layer, often needs further investigation to be proved. Chemical characterization, carried out in a non or micro destructive way, can be crucial to provide useful information about the original composition, degradation process, realization technique, in obtaining an indirect dating of the photograph and/or to choose the most correct conservation treatment. In our case, x-ray fluorescence (XRF) analysis was used to confirm the chemical composition of eleven historical photographs dated between the end of the 19th century and the beginning of the 20th, shot in Palermo (Sicily) by a renowned photographer of the time, and pasted on their original cardboards. The elemental identification, obtained with a non destructive approach, provided important information to distinguish among different photographic techniques in terms of distribution and characterization of chemical elements markers in the photographic surface. - Highlights: • Overview of the photographic processes used in the early XX century. • X-ray fluorescence used to characterize photographs made by different techniques. • Diagnostic and conservative approach in the photographic material restoration. • Non invasive approach in studying photographic materials.

    Equal representation within higher education science, technology, engineering, and mathematics (STEM) fields and the STEM workforce in the United States across demographically diverse populations is a long-standing challenge. This study uses two-to-one nearest-neighbor matched-comparison group design to examine academic achievement, pursuit of graduate science degree, and classification of graduate institution attended by students participating in the Hopps Scholars Program (Hopps) at Morehouse College. Hopps is a highly structured enrichment program aimed at increasing participation of black males in STEM fields. Morehouse institutional records, Hopps Program records, and National Student Clearinghouse data were used to examine differences between Hopps and non-Hopps STEM graduates of Morehouse. Two-way sample t tests and chi-square tests revealed significant differences in academic achievement, likelihood of STEM degree pursuit, and the classification of graduate institutions attended by Hopps versus non-Hopps students. Hopps Scholars were significantly more likely than non-Hopps STEM graduates both to pursue STEM doctoral degrees and to attend doctoral-granting institutions with higher research activity. The Hopps Program's approach to training black male students for scientific careers is a model of success for other programs committed to increasing the number of black males pursuing advanced degrees in STEM. © 2016 R.

    In the summer of 2001 and 2004 I experienced internships at the NASA/ Goddard Space Flight Center in Greenbelt, MD. Through these internships I was introduced to Geographical Information Systems and Remote Sensing. My experiences at NASA have also helped me acquire the ability to learn how I can now best utilize my networking contacts at NASA and other connections to facilitate my future plans as an engineer working on Indian and non-Indian Reservation lands. My experiences working at a large agency such as NASA have shown me the significance how a Native American engineer can strive to improve and preserve Indian and non-Indian lands for future generations. Formulating new and inventive methodologies on how to better approach Indian Reservation research while incorporating Native American culture I feel are vital for success. My accomplishments throughout the recent past years have also allowed me conduct outreach to Indian K-12 kids and college students alike.

    The ductile tearing resistance of steels is generally characterized in terms of resistance curves giving the increase of a resistance parameter such as the crack driving force J or a crack opening displacement as a function of the crack extension {Delta}a. Welded joints are often the weakest part of structures because of greater risk of defects, heterogeneity of the microstructure of the weld, strain concentration along mismatched interfaces. This paper recalls the transferability issues common to all integrity assessments based on tearing resistance curves and points out the difficulties of characterization specific to welds. Several recommendations are proposed for the experimental determination of tearing resistance of welded joints. (authors)

    In contrast to a recent claim by Sánchez and Aldao [Phys. Rev. B 54, R11 058 (1996)] that the relaxation dynamics of attachment processes influences the equilibrium step structure we argue that the step structure in thermodynamic equilibrium is only governed by the configurational free energy

    Full Text Available As larvas da Dermatobia hominis provocam lesões ulcerativas, danificando o tecido subcutâneo e conseqüentemente a pele do hospedeiro. O couro é o subproduto que sofre maior depreciação, o que, muitas vezes, impossibilita seu aproveitamento na industrialização. Atualmente o controle químico é utilizado como forma de combate à dermatobiose, entretanto, leva ao acúmulo de substâncias tóxicas nos animais e no ambiente. No presente trabalho, foram avaliadas as respostas imune-humoral e celular de bovinos imunizados com extrato antigênico preparado com larvas de D. hominis. Três grupos de oito bezerras da raça Nelore com 10 meses de idade foram usados, tendo o primeiro grupo (A recebido aplicação de extrato imunogênico de larvas de D. hominis, com intervalos de quinze dias; o grupo (B, utilizado como controle, não recebendo nenhum tipo de tratamento; e o grupo (C recebendo o tratamento ectoparasiticida à base de Dichlorvos associado a Cypermetrina. Neste mesmo período, foram avaliados o leucograma e os níveis de IgG contra D. hominis pela técnica de enzimoimunoensaio-ELISA. Quanto à avaliação da imunidade humoral, verificou-se que os animais do grupo A apresentaram maior produção de IgG contra D. hominis, com níveis máximos de anticorpos circulantes aos 45 dias após a primeira imunização. Estes animais também apresentaram maior produção de neutrófilos, eosinófilos e monócitos que os dos grupos B e C. O número de nódulos de larvas encontrado nos animais do grupo C foi 148,3% maior que nos animais dos grupos A e B. A comprovação da resposta imune celular e humoral, parcialmente caracterizadas, bem como a redução do número de nódulos, são indicadores que a imunização contra D. hominis foi parcialmente protetora para os bovinos imunizados.Dermatobia hominis larvae cause ulcerative lesions and damage to subcutaneous tissue and skin of the host. Leather is the subproduct which undergoes major depreciation, making it difficult to industrial use. Nowadays, the chemical control is utilized against dermatobiosis, therefore it leads to rising toxic chemicals in the animals and environment. The immunological challenge with D. hominis larval extract may represent an important altervative for this parasitosis control. Humoral and cellular immune responses were tested in bovine using an antigenic extract prepared with D. hominis larvae. Three groups of 10 months old Nelore females were used. The first group (A received immunogenic larval extract of D. hominis with fifteen-days interval between injections; the group (B was the control and has not received any sort of treatment; and the group (C received an ectoparasitecide treatment based on Dichlorvos associated to Cypermetrina. Aditionally, leucogram and levels of IgG against D. hominis by immunoassay technique were evaluated. As for the humoral immunity, animals from group A presented higher IgG production against D. hominis with maximum levels of circulating antibodies at the 45th day after the first injection. These animals also showed higher production of neutrophils, eosinophils and monocytes than those from groups B and C. The number of D. hominis larvae nodules observed in animals from the group C was 148.3% larger than those from group A and B. The evidence concerning both cellular and humoral immune responses as well as the reduction on nodules number are an indication that the immunization against D. hominis was partially protective for the immunized bovines.

    Full Text Available The aim of this note was to record for the first time the finding of Hemilucilia segmentaria acting as biological vector of Dermatobia hominis, during a study of the diversity of Calliphoridae at Reserva Biológica do Tinguá, Rio de Janeiro, Brazil. The insects were captured using traps baited with chicken vicera, for a period of 28-30 h twice per month. In the period of one year, 1987 insects were collected, 7.5% of which belonged to the H. segmentaria; of these a female was captured in May 2001, carrying a mass of 20 eggs on the left side of its abdomen.

    While a recent paper by Cox in this journal uses as its motivating factor the benefits of quantitative risk assessment, its content is entirely devoted to critiquing Sneeringer's article in the American Journal of Agricultural Economics. Cox's two main critiques of Sneeringer are fundamentally flawed and misrepresent the original article. Cox posits that Sneeringer did A and B, and then argues why A and B are incorrect. However, Sneeringer in fact did C and D; thus critiques of A and B are not applicable to Sneeringer's analysis.

    Whilst the overall proportion of young people drinking alcohol in the United Kingdom has decreased in recent years, those who do drink appear to drink a larger amount, and more frequently. Early and heavy drinking by younger adolescents is a significant public health problem linked to intellectual impairment, increased risk of injuries, mental health issues, unprotected or regretted sexual experience, violence, and sometimes accidental death, which leads to high social and economic costs. This feasibility pilot trial aims to explore the feasibility of delivering brief alcohol intervention in a school setting with adolescents aged 14 and 15 and to examine the acceptability of study measures to school staff, young people and parents. Seven schools across one geographical area in the North East of England will be recruited. Schools will be randomly allocated to one of three conditions: provision of an advice leaflet (control condition, n = 2 schools); a 30-minute brief interactive session, which combines structured advice and motivational interviewing techniques delivered by the school learning mentor (level 1 condition, n = 2 schools); and a 60-minute session involving family members delivered by the school learning mentor (level 2 condition, n = 3 schools). Participants will be year 10 school pupils (aged 14 and 15) who screen positively on a single alcohol screening question and who consent to take part in the trial. Year 10 pupils in all seven schools will be followed up at 6 and 12 months. Secondary outcome measures include the ten-question Alcohol-Use Disorders Identification Test. The EQ-5D-Y and a modified short service use questionnaire will inform the health and social resource costs for any future economic evaluation.Young people recruited into the trial will also complete a 28-day timeline follow back questionnaire at 12-month follow-up. A qualitative evaluation (with young people, school staff, learning mentors, and parents) will examine facilitators and barriers to the use of screening and brief intervention approaches in the school setting in this age group. Trial reference number ISRCTN07073105.

    Full Text Available San Ignacio, en el Valle de Potrerillos, fue habitado durante los siglos III-VIII D.C. por grupos humanos que construyeron hornillos y ocuparon casas semi-subterráneas. Constituye uno de los escasos registros sistemáticos de contextos domésticos para el valle. Se presenta y caracteriza el sitio mediante el análisis osteométrico de camélidos, la organización de la tecnología lítica y el análisis tipológico y morfo-funcional cerámico. Las diversas actividades domésticas desarrolladas combinaron la explotación de camélidos silvestres y domésticos, además de cultígenos. Los rasgos arquitectónicos y los patrones materiales del interior de la unidad habitacional, se relacionan con una ocupación anticipada de tipo permanente. La cerámica analizada fue asignada al estilo Agrelo-Calingasta del período Agro-alfarero Temprano-Medio de la arqueología regional. El asentamiento podría insertarse en un circuito de movilidad para el aprovechamiento de diversos recursos en ambientes de altura. Además se sugiere la participación en redes de intercambio, evidenciada por la presencia de cerámica similar a la de los complejos culturales que se desarrollaron en la vertiente occidental de Los Andes y por la identificación de un morfotipo de camélido especialmente grande, propicio para la realización de caravanas.   Palabras clave: Valle de Potrerillos; Período Agro-alfarero regional; Contexto Doméstico; Camélidos silvestres y domésticos; Redes de Intercambio.   Abstract San Ignacio, in the Valley of Portrerillos was occupied during the third to eighth centuries A.D. by groups that constructed pit ovens and occupied semi-subterranean houses. It is one of the few systematically recorded domestic contexts in the valley. The site is presented and characterized through the osteometric analysis of camelids, the organization of lithic technology, and typological and morphofunctional analyses of ceramics. Diverse domestic activities combined the exploitation of wild and domestic camelids, as well as cultigens. Architectural features and material patterns from the interior of the habitation imply a permanent occupation. The analyzed ceramics were associated with the style Agrelo-Calingasta from the regional Early-Middle Agro-ceramic period. The settlement may be part of a mobility circuit for the utilization of diverse resources in high altitude zones. Moreover, participation in exchange networks is suggested by the presence of ceramics similar to those used by cultural complexes on the western slopes of the Andes and the identification of an especially large camelid morphotype, apt for carrying out caravans.

    This paper continues our efforts to determine which modality is best for presentation of stimuli in the P300-based concealed information test (CIT) called the Complex Trial Protocol (CTP). The first part of the CTP trial involves presentation of the key probe or irrelevant stimuli, and is followed by presentation of target (T) or non-target (NT). In Rosenfeld et al. (2015), probes and irrelevants regularly alternated modality over trials, but Ts and NTs were always visual. In the present study, (in both its experiments, EXP 1 and EXP 2), probes and irrelevants alternated modalities on successive trials, as before. In present EXP 1, Ts and NTs were always auditory, but in EXP 2, they were simultaneously auditory and visual. Probe P300 data were different in each study: In Rosenfeld et al. (2015) and EXP 2 here, the bootstrap-based detection rates based on probe-minus-irrelevant differences, significantly differed favoring visual probe and irrelevant presentation modality. In EXP 1 here, detection rates were the same for the two modalities. In Rosenfeld et al. (2015) there was no main effect of probe modality, visual vs. auditory on probe-minus-irrelevant P300 difference. There were such effects here in EXP 1 (pvisual modality. Probe P300 latencies were shorter for visual than for auditory stimuli in Rosenfeld et al. (2015), a trend specifically reversed in the present pair of studies. RT was faster for visual stimuli in the present studies. The T and NT modality appears to interact with probe/irrelevant modality, and the best protocol for detecting concealed information is with the 2015 study protocol or that of EXP 2, using visual stimulus presentation.

  13. [The relevance of junctional rhythm during neurocardiogenic reaction provoked by tilt testing].

    Science.gov (United States)

    Zyśko, Dorota; Gajek, Jacek; Agrawal, Anil Kumar; Rudnicki, Jerzy

    2012-01-01

    During neurocardiogenic reaction provoked by tilt testing (TT), different arrhythmias such as sinus bradycardia, sinus arrest, atrioventricular block or junctional rhythm or beats (JR) may occur. The characteristics of the JR during neurocardiogenic reaction have not yet been systematically assessed. It is not known whether the presence of JR during neurocardiogenic reaction is related to clinical characteristics of syncopal patients or the outcome of TT. To assess whether clinical outcome of TT and clinical data are related to the presence of JR during TT. The study group consisted of 532 patients aged 43.3 ± 18.2 years with positive TT, divided into four groups on the basis of the presence of JR and/or a ventricular pause (VP) during neurocardiogenic reaction: group VP(-)/JR(+) - JR present and VP absent, group VP(+)/JR(+) - both JR and VP present, group VP(+)/JR(-) - JR absent and VP present, and group VP(-)/JR(-) - both JR and VP absent. The control group consisted of 53 patients with no history of syncope or presyncope, including 46 patients with negative TT and seven patients with false positive TT. Total loss of consciousness during TT occurred in group VP(-)/JR(+) less frequently than in groups VP(+)/JR(+) and VP(+)/JR(-), and more frequently than in group VP(-)/JR(-) (80% vs 96% vs 94% vs 62%; p 〈 0.05 for both comparisons). Group VP(-)/JR(+) was significantly younger than group VP(-)/JR(-) (37.3 ± 16.3 years vs 45.8 ± 18.9 years; p 〈 0.05) and had a lower number of syncopal events than group VP(+)/JR(+) and VP(+)/JR(-) (median [IQ]: 2.5 (1-6) vs 4 (2-12) and 4 (2-10), respectively; p 〈 0.05) and lower rate of traumatic injuries than group VP(+)/JR(+) and VP(+)/JR(-) (22% vs 45% and 39%, respectively; p 〈 0.05). Logistic regression analysis revealed that the presence of JR was associated with younger age, male gender, history of blood-instrumentation-injection phobia and higher number of syncopal spells in medical history.

    There is limited literature on renal oncocytic neoplasms diagnosed on core biopsy. All renal oncocytic neoplasm core biopsies from 2006 to 2013 were, retrospectively, reviewed. Morphologic features and an immunohistochemical panel of CK7, c-KIT, and S100A1 were assessed. Concordance with resection diagnosis, statistical analysis including a random forest classification, and follow-up were recorded. The postimmunohistochemical diagnoses of 144 renal oncocytic core biopsies were favor oncocytoma (67%), favor renal cell carcinoma (RCC) (12%), and cannot exclude RCC (21%). Diagnosis was revised following immunohistochemistry in 7% of cases. The most common features for oncocytoma (excluding dense granular cytoplasm) were nested architecture, edematous stroma, binucleation and tubular architecture; the most common features for favor RCC were sheet-like architecture, nuclear pleomorphism, papillary architecture, and prominent cell borders. High nuclear grade, necrosis, extensive papillary architecture, raisinoid nuclei, and frequent mitoses were not seen in oncocytomas. Comparing the pathologist and random forest classification, the overall out-of-bag estimate of classification error dropped from 23% to 13% when favor RCC and cannot exclude RCC was combined into 1 category. Resection was performed in 19% (28 cases) with a 94% concordance (100% of favor RCC biopsies and 90% of cannot exclude RCC biopsies confirmed as RCC; 83% of favor oncocytomas confirmed); ablation in 23%; and surveillance in 46%. Follow-up was available in 92% (median follow-up, 33 months) with no adverse outcomes. Renal oncocytic neoplasms comprise a significant subset (16%) of all core biopsies, and the majority (78%) can be classified as favor oncocytoma or favor RCC. Copyright © 2017 Elsevier Inc.
