In a liquid due to the structural correlation the total entropy is less than the corresponding ideal gas entropy. Thus, the excess entropy has a negative.

  3. 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.

  13. A short history of nuclear activities in Mendoza province

    International Nuclear Information System (INIS)

    Lardone, Leo E.

    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

  16. On understanding projective identification in the treatment of psychotic states of mind: the publishing cohort of H. Rosenfeld, H. Segal and W. Bion (1946-1957).

    Science.gov (United States)

    Aguayo, Joseph

    2009-02-01

    A publishing cohort of Kleinian analysts - Rosenfeld, Segal and Bion - implemented Klein's (1946) notions of projective identification and the 'paranoid ' and 'schizoid ' positions in the understanding of a group of psychotic disorders. The author differentiates Klein's (1946)Notes on some schizoid mechanisms paper from its revised version of 1952, maintaining that it was Rosenfeld's clinical work during this period that helped to centralize Klein's redefinition of projective identification. The stage was set for Segal 's contribution in terms of 'symbolic equations,' where the psychotic's attack on the breast left him incarcerated in internal torment and persecution, where things-in-themselves were confused with what they symbolically represented. Segal in turn linked psychotic to normal, paranoid-schizoid to depressive positions, where by means of projective identification and symbolic imagination, the patient could arouse feelings in the analyst related to sadness, guilt and loss. Bion assumed that psychotic pathology reflected disordered thinking, when the severely disturbed used language as a mode of action. The psychotic was profoundly confused between the use of thought and action in the natural world - where thought was required, he preferred action and vice versa. Bion also drew upon projective identification in a new, broader way, so that analysis could now become more of an intersubjective, bi-directional field of projective and communicational influence between patient and analyst. The paper concludes with the impact of the work of Rosenfeld, Segal and Bion and variations on the technique of analyzing psychotic states in terms of the patient's early history, transference and countertransference.

  17. Multivariable modeling of J-R data

    International Nuclear Information System (INIS)

    Eason, E.D.; Wright, J.E.; Nelson, E.E.

    1991-01-01

    Current methods for evaluating safety and remaining life issues for reactor pressure vessels (RPV's) and piping are based on the J-R curve. Unfortunately, field-aged J-specimens are not always available for the specific weld or heat in service or at the radiation conditions which match the case to be analyzed. In order to best evaluate plant safety, therefore, it is necessary to reliably estimate a J-R curve from available data, such as material chemistry, radiation exposure, tensile properties, and Charpy data. A multivariable model for predicting J-R curves from available data, such as material chemistry, radiation exposure, and Charpy data, is being developed. This is an interim report on a project to collect public test data, apply advanced pattern recognition tools, and fit an improved model. A four-parameter model for the dependence of J d on crack extension, Charpy energy, temperature, and specimen thickness is presented

    Full Text Available The objectives of the present study were the analysis of cell counts, the comparison between different methods for counting cells and the quantification of different types of cells observed in the milk of Lacaune sheep, using automatic somatic cell counts (SCC and direct microscopic SCC. Milk smears were stained with methyl green-pyronin-Y and Rosenfeld stain. Mean of  automatic cell counts was 0.145 x106 cells/mL of milk, and mean of direct microscopic counts using methyl green-pyronin-Y and Rosenfeld were respectively 0.157 and 0.193 x106 cells /mL of milk. Samples used in direct microscopic counts were evaluated according to the different types of cells and the following results were recorded: 0.094 and 0.14 x106 mononuclear cells /mL, 0.063 and 0.051 x106 polymorphonuclear cells /mL of milk using methyl green-pyronin-Y and Rosenfeld stain, respectively. It may be concluded that there were differences in the methods used for counting cells. The number of cells recorded was lower when methyl green-pyronin-Y and automatic counts were used, compared with direct microscopy using Rosenfeld stain.

    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)

  1. Urban mobility regulation in metropolitan area of Mendoza

    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.

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

    International Nuclear Information System (INIS)

    Rodrigo, F.; Belluco, A.E.

    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

    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)

    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.

    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

    Full Text Available El análisis de la evolución de Mendoza en el siglo XVII permite diferenciar las características de un asentamiento en la periferia de aquellas características que corresponden a una sociedad de frontera. Fundada en 1561 en la periferia imperio español en América a principios del siglo XVII, Mendoza era una comunidad con escasa población, con reducido comercio y de lento desarrollo urbano; todas características de las colonias periféricas. A lo largo de la primera parte del siglo XVII, sin embargo, Mendoza se fue configurando como una sociedad de frontera. Las causas de este devenir frontera se relacionan con la revuelta araucana y con las consecuencias del establecimiento de la frontera geográfico-militar en el río Biobio. El trabajo comienza con una revisión de los términos frontera y periferia tal como se encuentran empleados en los análisis de algunos autores representativos de la historiografía sobre fronteras para las Américas. Luego se reconstruye la evolución de periferia a frontera en Mendoza; un proceso que comenzó varias décadas después de su fundación en 1561. Tal fundación no estuvo guiada por la necesidad de consolidar o de proteger una zona de frontera, de modo que no fue fundada ni como presidio ni como misión, que son las típicas instituciones de frontera y que encontramos en numerosas fronteras del imperio español, como ser en la Florida y en el norte de México. A fines del siglo XVI Mendoza fue fundada como uno de los tantos asentamientos que permitirían a los españoles seguir avanzando en la conquista y colonización de nuevos territorios. Sin embargo, la revuelta araucana de 1598-1599 provocó el quiebre de tal desenvolvimiento de la conquista porque truncó la esperanza de una futura expansión española hacia el sur. Más allá del fiasco militar de la derrota de Curalaba, la rebelión nativa obligó a la coronaa establecer un ejército profesional de alrededor de 2.000 hombres, cuya permanencia

    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.

    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.

    Full Text Available The cacicazgo, or indigenous lordship, was a pivotal institution in colonial Mexican Indian pueblos. Caciques, or Indian nobles, played a role, both in the largely indigenous world of the pueblo and in the regional economy that was dominated by Spaniards. This subject of this essay is the analysis of the evolution and daily operation and of a cacicazgo from the Indian settlement of Tepexí de la Seda near the city of Puebla de los Ángeles and the life of its caciques in the sixteenth and seventeenth centuries. In the sixteenth century the cacicazgo was in upheaval because of discord between the cacicazgos and their dependent Indians. A number of long-running accounts from the 1620s record in detail the daily operations of the cacicazgo of Doña Ana de Santa Bárbara of the Mendoza family, thus illustrating how caciques negotiated their positions and coped with their lives and the changes in it.   Resumen: Un cacicazgo colonial: los Mendoza de Tepexí de la Seda en el siglo 17 El cacicazgo, o señorío indígena, fue una institución fundamental en los pueblos indios de México colonial. Los caciques, o nobles indígenas, desempeñaron un papel tanto en el mundo en gran parte indígena del pueblo y en la economía regional dominada entonces por los españoles. El tema de este ensayo es el análisis de la evolución y operación cotidianas de un cacicazgo del asentamiento indígena de Tepexí de la Seda cerca de la ciudad de Puebla de los Ángeles y la vida de sus caciques en los siglos 16 y 17. En el siglo 16, el cacicazgo vivió tiempos convulsos debido a los conflictos entre los caciques y sus dependientes indios. Varias extensas cuentas de los años veinte del siglo 17 registran en detalle las operaciones diarias del cacicazgo de doña Ana de Santa Bárbara, de la familia Mendoza, mostrando así cómo negociaban los caciques sus posiciones y se adaptaban a los cambios en sus vidas.

    Due to the importance of the winemaking sector in Mendoza, Argentina, the assessment of future scenarios for viticulture is of foremost relevance. In this context, it is important to understand how temperature increase and precipitation changes will impact on grapes, because of changes in grapevine phenology and suitability wine-growing regions must be understood as an indicator of climate change. The general objective is to classify the suitable areas of viticulture in Argentina for the current and future climate using the MM5 regional climate change simulations. The spatial distribution of annual mean temperature, annual rainfall, and some bioclimatic indices has been analyzed for the present (1970-1989) and future (2080-2099) climate under SRES A2 emission scenario. In general, according to projected average growing season temperature and Winkler index classification, the regional model estimates (i) a reduction of cool areas, (ii) a westward and southward displacement of intermediate and warm suitability areas, and (iii) the arise of new suitability regions (hot and very hot areas) over Argentina. In addition, an increase of annual accumulated precipitation is projected over the center-west of Argentina. Similar pattern of change is modeled for growing season, but with lower intensity. Furthermore, the evaluation of projected seasonal precipitation shows a little precipitation increase over Cuyo and center of Argentina in summer and a little precipitation decrease over Cuyo and northern Patagonia in winter. Results show that Argentina has a great potential for expansion into new suitable vineyard areas by the end of twenty-first century, particularly due to projected displacement to higher latitudes for most present suitability winegrowing regions. Even though main conclusions are based on one global-regional model downscaling, this approach provides valuable information for implementing proper and diverse adaptation measures in the Argentinean viticultural

    This work focuses on two main objectives. One of them is to provide information to discern the genesis of the circular structures present in Bajada del Diablo (Chubut, Argentina) considered as impact craters, and the other one is to contribute to a better knowledge of the circular structures located in the volcanic fields of Llancanelo and Payunia (Mendoza, Argentina). Chubut circular structures have been attributed to the collision of an extraterrestrial body, possibly an asteroid. However, doubts persist about their genesis because of the lack of direct geological evidences. Since detailed geomorphological studies have ruled out an origin by wind deflation, the prevailing alternative hypothesis attributes these circular structures to a volcanic process. On the other hand, the study of the volcanic fields of Payunia and Llancanelo (Mendoza) will contribute to the knowledge of the mechanics of hydromagmatic processes in the area, and the origin of circular structures morphologically similar to those located in Chubut. In the Payunia volcanic field at least 27 cones with evidences of hydromagmatism, in a field of more than 800 pure magmatic cones, have been recognized. This study tries to determine if a relationship between the observed volcanic circular structures and participation of water during the eruption exists. Magnetic and gravity field surveys of the circular volcanic structures in Llancanelo and Payunia volcanic fields were performed in order to determine their relationship with the type of eruption. Electromagnetic, magnetic and gravity field surveys were also carried out in Chubut circular structures. The comparative analysis of geological and geophysical results obtained in the circular structures of Chubut and those obtained in the circular structures in the volcanic areas of Llancanelo and Payunia suggest an impact origin for the circular structures of Chubut.

    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 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.

    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. Wide sectors of the Mendoza population saw their life conditions and social interactions change as a result of the absorption of a significant amount of immigrants by the end of 19 th century, together with a restructuring of production connected to the development of the wine industry. Shortly after the turn of the century, wine had become the main productive activity of that

    Although large historical earthquakes occurred in the Andean back-arc region between 28° and 34°S - for instance Mendoza was destroyed by an earthquake of magnitude MS = 7.0 in 1861 - the slip rates of active faults remain unknown. We report a slip rate for the 50-km-long Las Penas thrust, which constitutes the frontal thrust of the Precordillera. In its southern part, a well preserved fluvial terrace along La Escondida Creek (Costa et al., 2000) is displaced vertically by 10.6 ± 0.7 m as documented by several fault scarp profiles. Apart from radiocarbon dating of plant remnants, three different approaches for 10Be exposure dating have been applied to constrain the age of the terrace. Amalgamated sandstone pebbles (corrected for an inherited 10Be component using similar pebbles from the active creek) and a depth profile obtained from four sand samples yield 10Be exposure ages of 12.2 ± 1.5 and 11.3 ± 2.0 kyr, respectively. Both ages are in excellent agreement with the 14C age of 12.61 ± 0.20 cal kyr BP. In contrast, 10Be ages of five sandstone boulders vary significantly and exceed the age of the terrace by 10 to 70 kyr, which demonstrates that the widely used assumption of a negligible inherited component is not valid here. The age of the river terrace combined with the vertical fault offset yields an uplift rate of ~0.8 mm/yr for the Las Penas thrust. Combined with the fault dip of 25°, we determine a Late Quaternary horizontal shortening rate of ~1.8 mm/yr, which is about 40% of the GPS derived shortening rate of 4.5 ± 1.7 mm/yr in the back-arc region of the Andes (Brooks et al., 2003).

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.

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.

    NASA Administrator Charles Bolden (left) presents the Ambassador of Exploration Award (an encased moon rock) to Biloxi native and Apollo 13 astronaut Fred Haise Jr. (right) for his contributions to space exploration. During a Dec. 2 ceremony at Gorenflo elementary School in Biloxi, Miss., Bolden praised Haise for his overall space career and his performance on the Apollo 13 mission that was crippled two days after launch. Haise and fellow crewmembers nursed the spacecraft on a perilous trip back to Earth. 'The historic Apollo 13 mission was as dramatic as any Hollywood production,' Bolden said. 'When an explosion crippled his command module, Fred and his crewmates, Jim Lovell and Jack Swigert, guided their spacecraft around the moon and back to a successful splashdown in the Pacific Ocean - all while the world held its breath. While Fred didn't have the chance to walk on the moon, the cool courage and concentration in the face of crisis is among NASA's most enduring legacies.'

    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.

    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.

    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 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.

    Point-of-care testing (POC, POCT) laboratory devices are being introduced into operating suites and critical care units in ever increasing numbers. The small, portable devices have gained in popularity because of their ease of use and the rapid availability of test results. POCT is an integral part of extracorporeal technology (ECT). A challenge associated with the growth of POC technology is related to management of the data generated by these devices. In the field of ECT, storing, retrieving, analyzing, viewing and charting quality control (QC) and patient test data generated with POC coagulation instruments is essential. We evaluated a premarket version of data management software developed for the Hemochron Jr. Signature coagulation analyzer, a PC-based software capable of fulfilling our objective. A database comprised of greater than 50 plasma and electronic QC results and greater than 140 patient sample results for ACT, PT, and aPTT tests was transferred from a Hemochron Jr. Signature device to two different PCs, each equipped with Hemochron ReportMaker software supplied by the manufacturer. Data files were transferred directly from the coagulation test unit to the PCs via an RS-232 cable. A variety of charts, reports, and file listings were created from the datasets using the software menus. Transfer of the complete database required less than 5 min. The relative speed and simplicity of the data interface promotes frequent charting of QC data, permitting real-time monitoring and early identification of data trends or values requiring intervention. If a subset of QC data is found to be incomplete, altered, or unacceptable, all patient samples tested during that period can be promptly identified. The software also includes data query tools useful for sorting and selecting specific subsets of patient and QC data. Electronic data management can facilitate compliance with quality control requirements and assist clinicians and laboratory personnel in the

    Dr. Basil A. Pruitt Jr., a consummate clinical and translational surgeon-scientist, has been spent over half a century at the forefront of an advancing standard of burn care. Commanding the US Army Institute for Surgical Research in San Antonio, he trained generations of leading burn clinicians and allied scientists. At his direction, there were forged discoveries in resuscitation from shock, treatment of inhalation injury, control of burn-related infections, prevention of iatrogenic complications, and understanding the sympathetic, endocrine, and immune responses to burn injury. Most consequentially, this team was among the first recognize and define alterations in the basal metabolic rate and thermoregulation consequent to burn injury. These investigations prompted groundbreaking insights into the coordinated nervous, autonomic, endocrine, immune, and metabolic outflows that a severely-burned patient uses to remain alive and restore homeostasis. Marking his scientific consequence, many of his reports continue bear fruit when viewed through a contemporary lens. This paper summarizes some of the major findings of his career thus far, and is intended to complement a Festschrift recently held in his honor. Not applicable.

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.

    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.

    Full Text Available El artículo estudia los controles del Estado nacional y provincial a la agroindustria mendocina del vino entre la década de 1890 y 1914. En este período se detectan dos momentos. En el primero, entre 1890 y 1904, se analiza el mercado de vinos y cómo el Estado nacional utilizó los impuestos (aduaneros e internos para proteger a la naciente industria. También se reconstruye la legislación nacional y provincial que reguló la producción, la comercialización y el cobro de los impuestos al vino; y los mecanismos utilizados por ambas jurisdicciones para el cumplimiento de dichas leyes. En el segundo, se examinan los cambios ocurridos en la vitivinicultura durante los años de auge, entre 1904 y 1912, cuando los Estados provincial y nacional desplegaron estrictas normativas para evitar el fraude vínico y el pago del impuesto; y las primeras medidas tomadas con la llegada de una nueva crisis, entre 1913 y 1914. Abstract The article examines the controls of the national and provincial state to agribusiness Mendoza wine between the 1890 and 1914. In this period two points are detected.

    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.

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

    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.

    This paper describes different ways of reducing urban air temperature and their results in two cities: Campinas, Brazil—a warm temperate climate with a dry winter and hot summer (Cwa), and Mendoza, Argentina—a desert climate with cold steppe (BWk). A high-resolution microclimate modeling system—ENVI-met 3.1—was used to evaluate the thermal performance of an urban canyon in each city. A total of 18 scenarios were simulated including changes in the surface albedo, vegetation percentage, and the H/W aspect ratio of the urban canyons. These results revealed the same trend in behavior for each of the combinations of strategies evaluated in both cities. Nevertheless, these strategies produce a greater temperature reduction in the warm temperate climate (Cwa). Increasing the vegetation percentage reduces air temperatures and mean radiant temperatures in all scenarios. In addition, there is a greater decrease of urban temperature with the vegetation increase when the H/W aspect ratio is lower. Also, applying low albedo on vertical surfaces and high albedo on horizontal surfaces is successful in reducing air temperatures without raising the mean radiant temperature. The best combination of strategies—60 % of vegetation, low albedos on walls and high albedos on pavements and roofs, and 1.5 H/W—could reduce air temperatures up to 6.4 °C in Campinas and 3.5 °C in Mendoza.

    Rotavirus is one of the most common etiologic agents of acute diarrhea in childhood. Understanding the immunologic mechanisms involved in rotavirus diseases, including knowledge on seasonal and geographic antigenic variations may be crucial for vaccine development. A monoclonal antibody based ELISA specific for antigenic domains on the outer capsid protein VP7 has been developed and used widely in the past years. We studied the rotavirus VP7-serotype epidemiology causing diarrhea in children who consulted at two main hospitals of Mendoza, Argentina over a 20 month period. A total of 227 cases of diarrhea were identified, 45 of which (20%) were rotavirus positive. We're able to serotype 43 viruses (96%), 42 VP7-type 1 and one VP7-type 3. The VP7-type 3 was detected towards the end of the second year, possibly representing a new incoming VP7-type. Three electropherotype patterns were identified, two corresponding to VP7-type epidemiology in Mendoza, Argentina seems to be characterized by a relatively homogeneous pattern of circulation with a strong predominance of VP7-type 1 viruses, at least during the 20 month period studied, in contrast to what has been reported in larger, more cosmopolitan cities like Buenos Aires.

    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.

    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

    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

    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

    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

    2008-01-01

    Trained as an engineer and a chiropractor, William D. Harper, Jr. made his career in the healing arts as instructor, writer and president of the Texas Chiropractic College (TCC). A native of Texas who grew up in various locales in the Lone Star State, in Mexico and in the Boston area, he took his bachelor’s and master’s degree in engineering in 1933 and 1934 from the Massachusetts Institute of Technology, and his chiropractic degree at TCC in 1942. Dissatisfied with the “foot-on-the-hose” concept of subluxation syndrome (D.D. Palmer’s second theory), Dr. Harper studied and wrote about aberrant neural irritation as an alternative explanation for disease and for the broad clinical value he perceived in the chiropractic art. In this he paralleled much of D.D. Palmer’s third theory of chiropractic. His often reprinted textbook, Anything Can Cause Anything, brought together much of what he had lectured and written about in numerous published articles. He was well prepared for the defense of chiropractic that he offered in 1965 in the trial of the England case in federal district court in Louisiana. The case was lost when the court ruled that the legislature rather than the judiciary should decide whether to permit chiropractors to practice, but Harper’s performance was considered excellent. He went on to guide the TCC as president from 1965 through 1976, its first 11 years after relocating from San Antonio to Pasadena, Texas. Harper built the school – its faculty, staff and facilities – from very meager beginnings to a small but financially viable institution when he departed. Along the way he found fault with both chiropractic political camps that vied for federal recognition as the accrediting agency for chiropractic colleges in the United States. Dr. Bill Harper was a maverick determined to do things his way, and in many respects he was successful. He left a mark on the profession that merits critical analysis. PMID:18327301

    Ernest H. Cherrington, Jr., a long-time member of the AAS, died in San Jose, California on 13 July 1996, following a long illness. 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

    Three magnetotelluric soundings were carried out in the Triassic sedimentary basin in the northern part of province of Mendoza, Argentina (33{sup 0} C S - 69{sup 0} C W). The results show strata thickness and resistivity of the basement where underground water deposits (Quaternary) could be exploited; beneath these underground water deposits, there`s the Tertiary stratum, at about 2000 mt and with low resistivity. The presence of a conductive layer at an average depth of 9.5 km, would indicate the overthrust zone between the geologic provinces of Precordillera and Sierras Pampeanas. This contact has been determined near the working sites by deep reflection seismic. This result allows the search of this conductive layer intercalated along the orogenic front of the Precordillera towards both directions (North and South) from the sites under study.

    Full Text Available This paper outlines the development process of the capitalist viticulture in Mendoza. Using different primary and secondary sources, this study determines the composition of the viticulture labor and its quantitative and qualitative evolution. The introduction of up to date technology forced the training of manual labor with visible improvements in the workers' pay checks. This market became more complex through time showing multiple hierarchies in every rank of the work force, from peasants to wine makers. Several workers ascended the social ladder becoming managers due to diverse strategies traced through our various sources. Finally the workers' labor conditions indicate the vulnerability in which they were involved and their helplessness due to the lack of unions that could represent themEste artículo traza un breve panorama del proceso de desarrollo de la vitivinicultura capitalista en Mendoza y luego, utilizando diversas fuentes primarias y secundarias, determina la composición del mercado de trabajo vitivinícola y su evolución cuantitativa y cualitativa. La introducción de equipamiento técnico de avanzada obligó a la capacitación de la mano de obra con mejoras en los ingresos de los asalariados. Este mercado se complejizó con el tiempo y aparecieron múltiples jerarquías, desde el peón al enólogo o director técnico de las bodegas, pasando por los contratistas de viñas o los capataces. Muchos trabajadores ascendieron socialmente y se convirtieron en empresarios, en itinerarios que respondieron a diversas estrategias rastreables en las fuentes. Finalmente, las condiciones laborales que tuvieron los trabajadores muestran la precariedad en la que se desenvolvían y la indefensión en la que estaban inmersos por la ausencia de colectivos gremiales que asumieran la representación del trabajo frente al capital

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.

    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)

    Full Text Available This paper aims to unravel the formation of an eco-technocratic device behind the "techno-ecological practices" of some integrated agro-food producers. 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.

  18. A probability index for surface zonda wind occurrence at Mendoza city through vertical sounding principal components analysis

    Otero, Federico; Norte, Federico; Araneo, Diego

    2018-01-01

    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.

    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

    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

    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

    In this work, the partial results of the potential production of energy, starting from the biomass and the development of the crops, directed to the production of bio-fuels (Colza and Topinamur) in the North irrigation oasis of Mendoza, Argentina within the National Program of Bio-energy developed by INTA is presented. 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.

  11. John F. Kennedy, Jr. and the Torn Self: A Psychological Portrait.

    Ponterotto, Joseph G

    2017-01-01

    John F. Kennedy, Jr., (1960-1999) was one of the most recognizable figures of the 2nd half of the 20th century. He died tragically in an airplane he was piloting on route to Hyannis Port, Massachusetts to attend the wedding of his cousin, Rory Kennedy. Though much has been written about the life of J.F.K., Jr., this article represents the first psychobiographical portrait of the iconic personality. Employing a multi-theoretical approach to psychobiography, this profile integrates psychodynamic theory (James 1902/1982, Winnicott 1965), psychosocial development theory (Erikson 1950, 1980), and a modern theory of emerging adulthood (Arnett 2004) to develop a deep psychological portrait of the beloved son of President John F. Kennedy and Jacqueline Kennedy Onassis. J.F.K., Jr.’s life is traced along the four developmental periods of infancy and childhood, high school and college, emerging adulthood, and young adulthood. Psychobiography often focuses on unsolved mysteries in the lives of historic figures, and this profile of J.F.K., Jr., explores his search for his unique identity, whether he would have entered political life, and the likely future of his life with Carolyn Bessette Kennedy had they lived.

  17. Late Quaternary slip rates of two active thrust faults at the front of the Andean Precordillera, Mendoza, Argentina

    Science.gov (United States)

    Hetzel, R.; Schmidt, S.; Ramos, V. A.; Mingorance, F.

    2010-12-01

    Several destructive earthquakes occurred in the last several hundred years along the active mountain front of the Andean Precordillera between 30°S and 33°S (Siame et al., 2002). However, slip rates of active reverse faults remain largely unknown and the seismic hazard related to these faults is still poorly constrained. Here we report slip rates for two active thrusts located north of Mendoza, the Penas and Cal thrusts, which offset Late Pleistocene to Holocene terraces and form well preserved fault scarps. At the Penas thrust three terraces (T1, T2 and T3) are displaced vertically by 0.9, 2 and 11 m, respectively. 10Be and 14C age constraints yield a vertical slip rate of ~0.9 mm/a for the Penas thrust fault. Combined with the dip angle of the fault of ~25°, this leads to a horizontal shortening rate of about 2 mm/a. At the Cal thrust the highest terrace, which has a maximum 10Be age of 12 ka, is displaced by ~7.5 m. This translates into a minimum horizontal shortening rate of about 1 mm/a. Comparison with short-term GPS data (Brooks et al., 2003) suggests that both the Penas and Cal thrusts accomodate a significant portion of the present-day E-W shortening rate in the eastern Andes. The vertical surface displacements derived from the smallest scarps is 0.9 m for both thrusts. Hence, given their length (Penas thrust: 40 km, Cal thrust: 31 km), these faults are capable of producing magnitude 7 earthquakes (Wells & Coppersmith, 1994), which is confirmed by a Ms = 7.0 earthquake on the Cal thrust that destroyed the city of Mendoza in 1861. Assuming characteristic earthquakes for both faults suggests average reccurence intervals of 1000 to 1500 years during the Holocene.

    Full Text Available Existe acuerdo entre los expertos en transporte, planificación y urbanismo que la movilidad urbana es consecuencia de la organización espacial que adopta la ciudad y viceversa. Es decir, existe una estrecha relación entre las políticas de transporte y el ordenamiento del territorio. El objetivo de este trabajo es caracterizar la relación existente en la actualidad entre la organización territorial urbana de la zona del Gran Mendoza y el sistema de transporte masivo que opera en ella. Se estudia, particularmente, la existencia o no de las condiciones urbanas que propenden al uso del transporte masivo, ya que se considera que éste es de fundamental importancia para el desarrollo sustentable de las ciudades. Con este fin se utiliza el modelo conceptual de ciudades orientadas al transporte masivo, propuesto por Julio Pozueta (2000, y se aplica al caso en estudio. Se revisan también trabajos de otros autores tanto los referidos a la zona analizada, como aquellos de carácter más general que dan luz sobre las tendencias urbanas en el mundo y en particular en las ciudades de Latinoamérica.

    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.

    The feasibility of the application of chemometric techniques associated with multi-element analysis for the classification of grape seeds according to their provenance vineyard soil was investigated. Grape seed samples from different localities of Mendoza province (Argentina) were evaluated. Inductively coupled plasma mass spectrometry (ICP-MS) was used for the determination of twenty-nine elements (Ag, As, Ce, Co, Cs, Cu, Eu, Fe, Ga, Gd, La, Lu, Mn, Mo, Nb, Nd, Ni, Pr, Rb, Sm, Te, Ti, Tl, Tm, U, V, Y, Zn and Zr). Once the analytical data were collected, supervised pattern recognition techniques such as linear discriminant analysis (LDA), partial least square discriminant analysis (PLS-DA), k-nearest neighbors (k-NN), support vector machine (SVM) and Random Forest (RF) were applied to construct classification/discrimination rules. The results indicated that nonlinear methods, RF and SVM, perform best with up to 98% and 93% accuracy rate, respectively, and therefore are excellent tools for classification of grapes.

    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. This article shows the contrast between a powerful productive forces development and the miserable conditions of population life.

Le principal objectif de ce travail est d’analyser les effets hydrométéorologiques causés par ENSO dans la province de Mendoza, Argentine. Ensuite on étudiera les conditions météorologiques prédominantes (situations synoptiques les plus fréquentes et les phénomènes de méso-échelle associés pendant l’hiver, en plaine et dans la cordillère. On caractérise la zone étudiée hydrologiquement et climatologiquement. On utilise pour cela les données de débits mensuels des principales rivières de la région ainsi que les données climatiques, synoptiques et des images de satellite. Notre étude couvre les événements ENSO de ce siècle et plus particulièrement ceux de 1982-1983, 1986-1987, 1991-1993 et les premières manifestations de celui de 1997-1998. Les principaux résultats montrent, pour les années ENSO, une forte augmentation des débits des rivières à la fin du printemps et pendant l’été provoqué par l’excès de précipitation de l’hiver antérieur. Les plus forts débits ont été observés au cours de l'événement chaud de 1982-1983, considéré jusqu'à 1997 comme le plus fort de ce siècle. L’impact principal sur le régime hydrique est dû à l’anomalie positive de précipitations dans la partie de la cordillère qui a un régime hivernal. On en conclut que les plus fortes précipitations de la cordillère sont reliées à une augmentation de la fréquence des passages de zones de basse pression et d’incursions d’onde longue à des latitudes plus basses que la normale. Ceci provoque une anomalie négative dans le champ de pression de surface et des couches moyennes de l’atmosphère. El objetivo principal del trabajo es analizar los efectos hidrometeorológicos que ocasiona el evento cálido ENOS en la provincia de Mendoza, Argentina.

    Full Text Available During the last decade, the Deseadan (late Oligocene Quebrada Fiera locality, Mendoza Province, Argentina, has provided a large amount of mammal remains. Taxonomic studies have shown the presence of faunal elements common with other Deseadan associations from Patagonia and lower latitudes (Salla, Bolivia, as well as endemic taxa of different groups of mammals (Notohippidae, Leontiniidae, Homalodotheriidae, Hegetotheriidae, and Metatheria and even a gastropod. In this work, we present a taxonomic and phylogenetic analysis of a set of postcranial fossils of three families of the suborder Toxodontia (Notoungulata. The postcranial elements are assigned to taxa previously recognized at Quebrada Fiera, such as the leontiniid Gualta cuyana and the homalodotheriid Asmodeus petrasnerus, but also to the family Toxodontidae that is represented by Proadinotherium sp. and another larger toxodontid; a few dental remains of Proadinotherium are also included as this is the first time that toxodontids from Quebrada Fiera are described. In the case of A. petrasnerus, an almost complete calcaneum allows us to expand the diagnosis of this taxon. The bones assigned to G. cuyana enlarge the anatomical knowledge of this species. In turn, the presence of the genus Proadinotherium extends its geographic distribution in Argentina and adds to the extra-Patagonian record of P. saltoni from Salla, Bolivia. Phylogenetic results do not differ much from previous analyses using postcranial characters, and the obtained consensus trees show low node supports. The various phylogenetic analyses performed here provide a more robust framework to interpret the relationships of the studied taxa.

    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

    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

    La escasez de agua constituye un problema de Estado en las tierras secas de la provincia de Mendoza, Argentina. Sin embargo, mientras el gobierno local naturaliza y difunde la escasez como un problema “de todos”, los contrastes en el acceso al agua plantean interrogantes respecto de su universalidad. Por ello, este trabajo busca repensar la escasez hídrica desde una perspectiva multidimensional que amplíe el abordaje biofísico. Específicamente, se busca analizar la mirada oficial respecto de ...

    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

    About 2'230 vehicles per day pass through the National Road 7 that link Buenos Aires to Santiago de Chile, crossing Andes Cordillera. This extremely important corridor, being the most important land pass between Argentina and Chile, is exposed to numerous natural hazards, such as snow avalanches, rockfalls and debris flows and remains closed by natural hazards several days per year. This goal of this study is to perform a regional mapping of geohazard susceptibilities along the Road 7 corridor, as started by Baumann et al. (2005), using modern remote sensing and numerical approaches with field checking. The area of interest is located in the Mendoza Province, between the villages Potrerillos and Las Cuevas near the Chilean border. The diversity of soil and rock conditions, the active geomorphological processes associated to post-glacial decompression, seasonal freeze and thaw and severe storms along the road corridor, increase the risk to natural hazard. With the support of the European Space Agency (ESA Category-1 Project 7154), we have in this study processed a large number of ERS and Envisat ASAR scenes, covering the period from 1995 to 2000. We applied both the small-baseline (SB) and the persistent scatterer (PSI) multi-temporal interferometric SAR (InSAR) techniques. The study area contains sparse vegetation, and the SB InSAR method is therefore well suited to map the area containing mainly distributed scatterers. Furthermore, PSI algorithms are also used for comparison for selected landslides in the inventory. Both approaches show a relatively good coherence within mountain areas, which is a good point for the landslide detections along the road. Indeed, the authors identified several large slope instabilities even active scree deposits. This inventory is finally compared with field observations and with existing susceptibility maps regarding snow avalanches, debris-flows and rockfalls. The final objective of this project is to develop a risk strategy that

    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.

    In this study, the effect of shape parameters on the J-R curves of curved CT specimens was evaluated using the limit load method. Fracture toughness tests considering the shape factors L/W and Rm/t of the specimens were also performed. Thereafter, the J-R curves of the curved CT specimens were compared using the J-integral equation proposed in the ASTM (American Society for Testing and Materials) and limit load solution. The J-R curves of the curved CT specimens were also compared with those of the CWP (curved wide plate), which is regarded to be similar to real pipe and standard specimens.. Finally, the effectiveness of the J-R curve of each curved CT specimen was evaluated. The results of this study can be used for assessing the applicability of curved CT specimens in the accurate evaluation of the fracture toughness of real pipes.

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.

    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)

  1. Radial patterns of bitumen dykes around Quaternary volcanoes, provinces of northern Neuquén and southernmost Mendoza, Argentina

    Where the Neuquén Basin of Argentina abuts the Andes, hundreds of veins of solid hydrocarbon (bitumen) are visible at the surface. Many of these veins became mines, especially in the last century. By consensus, the bitumen has resulted from maturation of organic-rich shales, especially the Vaca Muerta Fm of Late Jurassic age, but also the Agrio Fm of Early Cretaceous age. To account for their maturation, recent authors have invoked regional subsidence, whereas early geologists invoked magmatic activity. During 12 field seasons (since 1998), we have tracked down the bitumen localities, mapped the veins and host rocks, sampled them, studied their compositions, and dated some of them. In the provinces of northern Neuquén and southernmost Mendoza, the bitumen veins are mostly sub-vertical dykes. They tend to be straight and continuous, crosscutting regional structures and strata of all ages, from Jurassic to Palaeocene. Most of the localities lie within 70 km of Tromen volcano, although four are along the Rio Colorado fault zone and another two are at the base of Auca Mahuida volcano. On both volcanic edifices, lavas are of late Pliocene to Pleistocene age. Although regionally many of the bitumen dykes tend to track the current direction of maximum horizontal tectonic stress (ENE), others do not. However, most of the dykes radiate outward from the volcanoes, especially Tromen. Thicknesses of dykes tend to be greatest close to Tromen and where the host rocks are the most resistant to fracturing. Many of the dykes occur in the exhumed hanging walls of deep thrusts, especially at the foot of Tromen. Here the bitumen is in places of high grade (impsonite), whereas further out it tends to be of medium grade (grahamite). A few bitumen dykes contain fragments of Vaca Muerta shale, so that we infer forceful expulsion of source rock. At Curacó Mine, some shale fragments contain bedding-parallel veins of fibrous calcite (beef) and these contain some bitumen, which is

    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.

    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

The tartaric acid, elaborated from wine making remainders, is essential to correct the low acidity of musts obtained in the wine argentine region. The aim is to tackle the conditions that led to the regional manufacture of this product, the tasks of regional and extra-regional businessmen and some of the problems they have faced. The hypothesis is that, besides the "induced" industries (metallurgy, cooperage, the modern viticulture and wine making have caused the birth and development of "derivative" industries, as that it is analyzedEl trabajo se refiere a las primeras experiencias para producir ácido tartárico en Mendoza, al comenzar el siglo XX. El ácido tartárico, elaborado a partir de los propios residuos de la vinificación, es esencial para corregir la baja acidez de los mostos obtenidos en la región vitivinícola argentina. El objetivo es abordar las condiciones que condujeron a la producción regional del insumo, el desempeño de actores sociales regionales y extra-regionales y algunos de los problemas que debió enfrentar la iniciativa empresarial. Se parte de la hipótesis de que, además de las industrias "inducidas" (metalurgia, tonelería, la vitivinicultura moderna provocó en Mendoza la puesta en marcha y el desarrollo de industrias "derivadas", como la que se analiza

El tema es relevante porque Argentina es actualmente la mayor potencia vitivinícola de América Latina y la quinta del mundo. El trabajo se ha realizado a partir de fuentes originales de los archivos de las ciudades de Mendoza, San Juan y Santiago de Chile, con el procesamiento de más de 400 mil datos sobre viñas, parrales y cepas. En el estudio se detectó que el 97% de las cepas se cultivaban en viñas y el solo 3% en parrales encatrados. Dentro de las primeras, el cultivo de las tres cuartas partes se hacía mediante el sistema en vaso, gobelet o cepas de cabeza (como se llamaba en América, mientras que el cuarto restante era embracerado: los sarmientos se conducían con varillas de sauce y álamo. Por lo general, las variedades de uva negra se cultivaban en cepas de cabeza y los moscateles en bracero o parrales encatrados.Parrales, braceros and gobelet were the three most utilized methods to cultivate grapevines in Mendoza and San Juan, since the founding of the capital of Cuyo Province in Chile´s Reign. These methods prevailed from the Spanish conquest of the area, in 1561, until the impact of French-like methods in Argentina’s vine-growing in the 1870s. This topic is relevant because Argentina is today the main wine producer in Latin America and the fifth largest producer in the world. This work has been prepared based on original sources from archives located in Mendoza, San Juan and Santiago, with the processing of more than 400,000 data regarding vineyards, vines and stocks of wine.

    Diverse datasets, including genomic, transcriptomic, proteomic and metabolomic data, are becoming readily available for specific organisms. There is currently a need to integrate these datasets within an in silico modeling framework. Constraint-based models of Escherichia coli K-12 MG1655 have been developed and used to study the bacterium's metabolism and phenotypic behavior. The most comprehensive E. coli model to date (E. coli iJE660a GSM) accounts for 660 genes and includes 627 unique biochemical reactions. An expanded genome-scale metabolic model of E. coli (iJR904 GSM/GPR) has been reconstructed which includes 904 genes and 931 unique biochemical reactions. The reactions in the expanded model are both elementally and charge balanced. Network gap analysis led to putative assignments for 55 open reading frames (ORFs). Gene to protein to reaction associations (GPR) are now directly included in the model. Comparisons between predictions made by iJR904 and iJE660a models show that they are generally similar but differ under certain circumstances. Analysis of genome-scale proton balancing shows how the flux of protons into and out of the medium is important for maximizing cellular growth. E. coli iJR904 has improved capabilities over iJE660a. iJR904 is a more complete and chemically accurate description of E. coli metabolism than iJE660a. Perhaps most importantly, iJR904 can be used for analyzing and integrating the diverse datasets. iJR904 will help to outline the genotype-phenotype relationship for E. coli K-12, as it can account for genomic, transcriptomic, proteomic and fluxomic data simultaneously.

    Full Text Available The definition of a town´s identity is a contemporary problematic. The process of economic globalization, far from devastating with the regional or national particularities seems to have exacerbated them. For that reason, to look for the bases of the national or regional identity in the present forces to be dig in our own history to try to find out the real or mythical origins of the same one. But the identity is not an easy or univocal concept or of an immediate apprehension. It was neither in the past nor in the present. For that reason, this article aims to introduce the problematic of the identity form the theory of the social representations and as a case applied to the City of Mendoza, Argentina.//La definición de la identidad de los pueblos es una problemática de absoluta vigencia contemporánea. El proceso de globalización económica vigente, lejos de arrasar con las particularidades regionales o nacionales parece que, en cambio, las ha exacerbado.Por ello, buscar las bases de la identidad nacional o regional en el presente, obliga a remitirse a la propia historia para tratar de escudriñar los orígenes reales o míticos de la misma.

    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.

    After the civil war and the Hurricane-Mitch disaster, cattlemen in Nicaragua were forced to transport their cattle from lowland areas to higher, dryer areas of the country. These areas are natural ecological niches for the cattle grub Dermatobia hominis (L. Jr.) (Diptera: Cuterebridae). To determine the importance of this infestation, the Agricultural and Livestock-Forestry Ministry selected a central area of Nicaragua to run a pioneer survey program to acquire information about hosts involved, number of cases, treatments applied and general knowledge of 42 farmers about the life cycle of the parasite. The subjects were either farm owners or farm managers. Ninety-five percentage of the farms indicated cases of D. hominis infestation in their animals, with cattle being the most affected host (100% of the affected farms). There was poor understanding of the D. hominis life cycle, vectors and control methods. A misuse of insecticides for the treatment of larval infestation by D. hominis was indicated.

    The crystallization and preliminary X-ray crystallographic analysis of a plant PPO exhibiting monophenolase activity from J. regia (jrPPO1) in its active form (Asp{sup 101}–Arg{sup 445}) are reported. Tyrosinase is a type 3 copper enzyme that catalyzes the ortho-hydroxylation of monophenols to diphenols as well as their subsequent oxidation to quinones, which are precursors for the biosynthesis of melanins. The first plant tyrosinase from walnut leaves (Juglans regia) was purified to homogeneity and crystallized. During the purification, two forms of the enzyme differing only in their C-termini [jrPPO1(Asp{sup 101}–Pro{sup 444}) and jrPPO1(Asp{sup 101}–Arg{sup 445})] were obtained. The most abundant form jrPPO1(Asp{sup 101}–Arg{sup 445}), as described in Zekiri et al. [Phytochemistry (2014 ▶), 101, 5–15], was crystallized, resulting in crystals that belonged to space group C121, with unit-cell parameters a = 115.56, b = 91.90, c = 86.87 Å, α = 90, β = 130.186, γ = 90°, and diffracted to 2.39 Å resolution. Crystals were only obtained from solutions containing at least 30% polyethylene glycol 5000 monomethyl ether in a close-to-neutral pH range.

    1991-05-01

    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

    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.

Also, children in the intervention group had less total screen time (-27.8 min/day, P = 0.05). 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 on 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.

    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...

    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

    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 Some isolated acanthomorph remains and a new taxon of perciform fishes, Saldenioichthys remotus gen. et sp. nov., from the Maastrichtian Saldeño Formation of Mendoza province, Argentina, are described and their systematic affinities are discussed. The new taxon is represented by a single incomplete, but well preserved postcranial skeleton. With the exception of a fully developed neural spine on the second preural centrum, it agrees with the generalized skeletal features of basal percoids, in particular the generalized perciform caudal skeleton. The only other Mesozoic perciform skeletal remains known so far are Nardoichthys, from the upper Campanian-lower Maastrichtian of Nardo (Italy and Eoserranus from the Upper Cretaceous Lameta Formation (India. Therefore, the new perciform taxon from the Saldeño Formation represents one of the oldest members of this group, and due to its peculiar combination of primitive and derived characters, it raises several questions regarding character evolution on this lineage. Es werden einige isolierte Reste acanthomorpher Fische sowie ein neues Taxon der Perciformes, Saldenioichthys remotus gen. et sp. nov., aus dem Maastricht der Saldeño Formation in der Provinz Mendoza, Argentinien, werden beschrieben und ihre systematische Stellung wird diskutiert. Das neue Taxon ist durch ein einziges, unvollständiges, aber gut erhaltenes postkraniales Skelett repräsentiert. Mit Ausnahme eines vollstandig ausgebildeten Dornfortsatzes auf dem ersten präuralen Zentrum stimmt es mit der generalisierten Skelettmorphologie basaler Percoiden überein, insbesondere mit dem generalisierten perciformen Caudal-Skelett. Die einzigen anderen Skelettreste von Perciformen aus dem Mesozoikum sind Nardoichthys aus dem Ober-Campan/Unter-Maastricht von Nardo, Italien, und Eoserranus aus der Oberkreide der Lameta Formation, Indien, und die Gruppe ist ansonsten praktisch nur aus känozoischen Sedimenten bekannt.

    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.

    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.

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...

    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.

O experimento foi delineado com os objetivos de avaliar: a a flutuação de larvas de Dermatobia hominis (Linnaeus Jr., 1781 em bovinos da raça Holandesa Preto e Branco criados no município de Palotina, e a distribuição desses ectoparasitos na superfície corporal de bovinos; e b a sazonalidade dos principais dípteros vetores de ovos de D. hominis. Para a captura dos insetos vetores, foram utilizados dois tipos de armadilhas: MAGOON e orientada pelo vento (wind oriented trap = WOT. Um total de 346 larvas foram expulsas por meio de compressão manual, sendo que a intensidade de larvas foi maior no lado esquerdo do animal, onde foi constatado um total de 240 nódulos (69,36%. Analisadas as freqüências de nódulos de berne nos animais, ficou demonstrado que houve diferença significativa (p>0,001 na tendência parasitária. Três regiões corpóreas foram mais parasitadas. A primeira é formada pelos membros torácicos, paletas e costelas; a segunda é formada pelo pescoço e flancos, e a terceira, formada pelas regiões dos membros pélvicos, barbela, ventre, cauda e tórax. Durante o período experimental foram capturados, nas armadilhas WOT e de MAGOON, 5.887 dípteros pertencentes a diferentes famílias. Verificou-se que as famílias Calliphoridae, Sarcophagidae e Muscidae foram as mais prevalentes.

    Emil Godlewski, Jr. (1875-1944) lived and worked in Krakow. He graduated from the Faculty of Medicine of the Jagiellonian University with the title of Doctor of Medical Science. He worked at the Faculty of Medicine, first in the Institute of Descriptive Anatomy and later as Professor of Biology and Embryology in the Department of Biology and Embryology, which he founded and led for many years. After early research on the development and histogenesis of muscles, professor Godlewski's scientific interests focused on regeneration and mechanisms regulating the process of fertilization, as well as early embryo development, blastulation and gastrulation. He was also interested in the origin of the primary differentiating cells in regenerates. He postulated the importance of epithelial tissue in this process and was the first to point out the change in the function, organization and role of the cells under the influence of external stimuli. Investigating fertilization and early development, he focused on the cooperation between the nucleus and the cytoplasm in the regulation of the early stages of development. Godlewski was also the author of the theory of migration of the inherited substances from the nucleus to the cytoplasm and, after their processing, from the cytoplasm to the nucleus. His works were never fragmentary, but always synthetical attempts at explaining important issues relating to the mechanisms of development. In 1936 Professor Godlewski was awarded the title of Member of the Pontifica Accademia delle Scienze. Apart from doing research and teaching, Emil Godlewski devoted a lot of time to social issues, especially those connected to medicine. When Poland regained independence after World War I, he actively participated in the reopening of the Jagiellonian University.

    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.

    Although large historical earthquakes occurred in the Andean back-arc region between 28° and 34°S, the slip rates of active reverse faults remain unknown; hence the seismic hazard related to these faults is poorly constrained. Here we report long-term slip rates for two faults - the Peñas and the Cal thrust - which define the front of the Andean Precordillera north of Mendoza. Both thrusts displace several Late Pleistocene to Holocene river terraces and form well-preserved fault scarps. At the Peñas thrust three terraces (T1, T2, and T3) are displaced vertically by ~0.9, ~1.9 and ~11 m, respectively. 10Be exposure dating constrains the age of T2 and T3 as 2.9 ± 0.8 ka and 11.1 ± 1.7 ka, which yields an uplift rate of 0.9 ± 0.1 mm/a. The horizontal shortening rate of the Peñas thrust - calculated by using the age of T3 and the dip angle of 25° - is 1.9 ± 0.2 mm/a. At the Cal thrust a fault scarp has displaced a terrace with a maximum age of 12 ka by 7 m. As the Cal thrust dips ~25°, this yields a shortening rate of ≥ 1.3 mm/a. Our results demonstrate that the two thrusts accomodate about half of the present-day shortening rate in the back-arc region of the Andes, which is constrained as 4.5 ± 1.7 mm/a (Brooks et al., 2003). Using the compilation of Well & Coppersmith (1994), the 50-km-long Peñas and the 31-km-long Cal thrusts are capable of producing earthquakes with a magnitude of Mw 6.7 to 7.0. This is supported by a magnitude Ms ~ 7.0 earthquake on the Cal fault, which devastated Mendoza in 1861 and killed two thirds of its population. Earthquakes of this magnitude have presumably generated the smallest fault scarps (~0.9 m vertical offset) present at both thrusts. The higher scarps are interpreted to record multiple offsets generated during several Holocene earthquakes.

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

En este trabajo pretendemos relevar a propósito de la celebración del sesquicentenario de Mayo la producción historiográfica mendocina que circuló en espacios de divulgación, constituyéndose en una fuerte tradición que perduró en los espacios académicos locales. 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.

    The type A of neurotoxin produced by Clostridium botulinum is the prevalent serotype in strains of Mendoza. The soil is the main reservoir for C.botulinum and is possibly one of the infection sources in infant botulism. In this study, we characterized and compared autochthonous C. botulinum strains and their neurotoxins. Bacterial samples were obtained from the soil and from fecal samples collected from children with infant botulism. We first observed differences in the appearance of the colonies between strains from each source and with the A Hall control strain. In addition, purified neurotoxins of both strains were found to be enriched in a band of 300 kDa, whereas the A-Hall strain was mainly made up of a band of ∼600 kDa. This finding is in line with the lack of hemagglutinating activity of the neurotoxins under study. Moreover, the proteolytic activity of C. botulinum neurotoxins was evaluated against SNARE (soluble N-ethylmaleimide-sensitive factor-attachment protein receptor) proteins from rat brain. It was observed that both, SNAP 25 (synaptosomal-associated protein 25) and VAMP 2 (vesicle-associated membrane protein) were cleaved by the neurotoxins isolated from the soil strains, whereas the neurotoxins from infant botulism strains only induced a partial cleavage of VAMP 2. On the other hand, the neurotoxin from the A-Hall strain was able to cleave both proteins, though at a lesser extent. Our data indicate that the C.botulinum strain isolated from the soil, and its BoNT, exhibit different properties compared to the strain obtained from infant botulism patients, and from the A-Hall archetype.

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.

    Full Text Available A partir de los años setenta y especialmente luego de los noventa, los territorios rurales de Argentina surcan profundas transformaciones estructurales. El nuevo modelo de acumulación asociado al auge del neoliberalismo traducirá en la implantación de un modelo financiero de agricultura fuertemente apoyado en la producción de commodities destinadas a la exportación. La producción sojera, considerada en Argentina un caso paradigmático de avance del capitalismo sobre la ruralidad, tendrá hondas repercusiones primero en territorios pampeanos y, luego, en territorios extrapampeanos que constituyeron su segundo frente de expansión. Sobre el oeste nacional, los territorios mendocinos y cada una de las actividades productivas que componen su ruralidad, experimentarán procesos de transformación y reconversión productiva de distinta envergadura. En este contexto, se analizan las transformaciones que se registran en la actividad ganadera de Mendoza en función del análisis exhaustivo de datos estadísticos y considerando prioritariamente una prolongación temporal de 20 años (1988-2008. La hipótesis señala que la ganadería mendocina acusa cambios que se corresponden con tendencias a la concentración de la producción, la introducción de tecnologías y el ingreso de capitales extranjeros, de lo que se desprende la desaparición de aquellos actores sociales que no computan como agentes competitivos en el sistema económico vigente.

    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 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 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. JR1 foi capaz de utilizar acetonitrila, em concentrações de 0,5 a 2M, como única fonte de carbono e de nitrogênio. A geração de amônia durante o crescimento do microrganismo indica a presença de sistema enzimático capaz de degradar acetonitrila. Durante os ensaios enzimáticos, com células cultivadas em acetonitrila, foram detectados ácido acético e acetamida como produtos indicando a presença de sistema enzimático capaz de degradar acetonitrila e acetamida.

    This special issue of the "Cardiovascular Drug Reviews" is dedicated in memory of Dr. Edward H. Ahrens, Jr., who died on Dec. 9th, 2000 at the Princeton Medical Center in New Jersey at the age of 85. Dr. Ahrens was the Director of the Lipid Metabolism Laboratory at the Rockefeller University. Dr. Alexander Scriabine conceived the idea for the issue at the special memorial symposium held at the Rockefeller University on Feb. 05, 2002 under the auspices of The New York Lipid and Vascular Biology Research Club. Dr. Ahrens was the first president of the club. He started this club with Drs. Howard Eder and DeWitt Goodman. Dr. Eder thought that it would be a fitting attribute to honor one of the founding fathers of the club by hosting a memorial symposium. I, as the President of the club for that academic year, had no hesitation in accepting the proposal. This year will be the 40th anniversary of the club and its continued success provides a glimpse of the fine legacy left behind by Dr. Ahrens. Dr. Ahrens also played a pivotal role in the establishment of the Journal of Lipid Research. This is the 43rd year of the journal and in this commemorative issue we are reproducing a review he wrote for the 25th anniversary of the journal. I was never personally acquainted with Dr. Ahrens. However, I am honored that I got this opportunity to pay tribute to a great scientist whose work has contributed immensely to the progress of lipid research. He was a person who touched many lives and still continues to do so. My involvement in the remembrance of Dr. Ahrens shows that science not only impacts your contemporaries but also generations that follow you. Scientific research is a journey where you can leave your trails behind and be remembered for your work long after your departure from this world. Dr. Ahrens contributed immensely to the understanding of cholesterol metabolism. In the early stages of his career he showed that phospholipids solubilize fat in the blood. Now we know

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.

  15. The Microcosm within: An interview with William B. Miller, Jr., on the Extended Hologenome theory of evolution.

    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.

    Parent artery occlusion (PAO) is an alternative to surgical clipping or endovascular endosaccular coil embolization for the management of cerebral aneurysms. Most giant and fusiform aneurysms are not amenable to endosaccular coil embolization due to anatomical considerations, such as a broad-neck. However, majority of reports regarding the safety of PAO are based on case series involving a relatively small number of patients. In the present study, a total of 381 consecutive patients with unruptured cerebral aneurysms who were treated with PAO were extracted from the Japanese Registry of Neuroendovascular Therapy (JR-NET) 1 and JR-NET2 database, which are nationwide surveys conducted by the Japanese Society of Neuroendovascular Therapy. The mean age of the 381 patients was 58.1 years, and 59.3% were female. The aneurysmal location included the vertebral artery (42%) and the cavernous portion of internal carotid artery (32%). The aneurysm size and shape consisted of fusiform (45%), giant (25%), and large (22%). Symptomatic lesions were present in 59.8% of the population. Technical success was achieved in 98.4%. The 30-day morbidity and mortality rates were 3.1% and 1.0%, respectively. The most frequent procedure-related complication was ischemic stroke, which occurred in 12.9% (distal embolism, 6.0%; branch occlusion, 3.9%). The 30-day morbidity and mortality rates related to ischemic strokes were 2.1% and 0.3%, respectively. PAO for unruptured aneurysms is feasible with a high technical success rate. Peri-procedural management of ischemic stroke is the key to enhance the safety of this treatment option.

Se tomaron 326 casos, construyendo una matriz de anomalías de temperatura (T y temperatura de punto de rocío (Td de los niveles estándar entre 850 y 300 hPa. El análisis arrojó 6 componentes significativas que explican más del 91% de varianza. Así se obtuvieron 12 patrones que representan condiciones atmosféricas diferenciadas. Las mayores correlaciones entre patrones y casos de convección (C y no convección (NC, se obtuvieron para las componentes 6, 2, 4 y 3. La convección se favorecería en entornos relativamente húmedos con un marcado gradiente de T en niveles medios y altos, mientras se inhibiría con capas secas en niveles medios y altos, y débiles gradientes de T en capas bajas. El indicador de C/NC puede estimarse por regresión múltiple logística dependiente de las componentes de carga, con una correlación conjunta de 0,5, determinando un índice de estabilidad/inestabilidad calculable a partir de los perfiles de T y Td y dependiente de las características climatológicas de la región.

El tipo de diseño de la investigación es no experimental retrospectiva porque no se manipulan las variables y se buscan datos del pasado. Fue evaluada una población de N=40 conformada por 28 nadadores, 8 entrenadores y 4 dirigentes de distintas épocas, con una encuesta para recolectar datos de los orígenes y evolución de la natación de competencia en Mendoza. 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. By using a mixed methodology, the paper analyse three dimensions: 1- The environmental resource supply, which is the basis of production activities, 2- The income attained by goat production units, and 3- The expenditures they face in terms of

    Full Text Available El objetivo del trabajo es generar conocimientos que permitan realizar propuestas conducentes a una mayor sostenibilidad energético-ambiental de los sistemas urbanos regionales, en función de sus características morfológicas y del recurso solar disponible. En una primera etapa se ha realizado un análisis de las zonas de alta densidad edilicia a partir de los resultados de indicadores relevantes y su análisis estadístico. Los indicadores expresan relaciones entre morfología urbana y acceso al recurso solar en el Área Metropolitana de Mendoza (AMM, e incluyen: Factor de Asoleamiento Efectivo (FAE y el Factor de Asoleamiento Volumétrico (FAV. Los resultados del análisis estadístico han permitido evaluar las correlaciones de cada variable morfológica sobre cada indicador, según distintas alternativas morfológicas y combinaciones de las mismas, lo que constituye la parte sustancial de este trabajo. En una segunda etapa se presentan los resultados parciales de un estudio que tiene como objetivo determinar los impactos energéticos ambientales de las recientes reformas del Código Urbano y de Edificación de la ciudad en estudio, en función del FAV y estimar la reducción del acceso al recurso solar respecto a la situación de referencia (actual, sin cambios y situación futura, en una ciudad con el carácter único de Mendoza como “ciudad-oasis”. Los resultados obtenidos hasta el momento indican que la reducción de la energía solar disponible por unidad de volumen construido sería sustancial: 46,32% para muros al norte y 60,38% techos.

    The La Peña alkaline igneous complex (LPC) is located in the Precordillera (32°41‧34″ S - 68°59‧48″ W) of Mendoza province, Argentina, above the southern boundary of the present-day flat-slab segment. It is a 19 km2 and 5 km diameter subcircular massif emplaced during the Miocene (19 Ma) in the Silurian-Devonian Villavicencio Fm. The LPC is composed of several plutonic and subvolcanic intrusions represented by: a cumulate of clinopyroxenite intruded by mafic dikes and pegmatitic gabbroic dikes, isolated bodies of malignite, a central intrusive syenite that develops a wide magmatic breccia in the contact with clinopyroxenite, syenitic and trachytic porphyries, a system of radial and ring dikes of different compositions (trachyte, syenite, phonolite, alkaline lamprophyre, tephrite), and late mafic breccias. The main minerals that form the LPC, ordered according to their abundance, are: pyroxene (diopside, hedenbergite), calcium amphibole (pargasite, ferro-pargasite, potassic-ferro-pargasite, potassic-hastingsite, magnesio-hastingsite, hastingsite, potassic-ferro-ferri-sadanagaite), trioctahedral micas (annite-phlogopite series), plagioclase (bytownite to oligoclase), K-feldspar (sanidine and orthoclase), nepheline, sodalite, apatite group minerals (fluorapatite, hydroxylapatite), andradite, titanite, magnetite, spinel, ilmenite, and several Cu-Fe sulfides. Late hydrothermal minerals are represented by zeolites (scolecite, thomsonite-Ca), epidote, calcite and chlorite. The trace element patterns, coupled with published data on Sr-Nd-Pb isotopes, suggest that the primary magma of the LPC was generated in an initially depleted but later enriched lithospheric mantle formed mainly by a metasomatized spinel lherzolite, and that this magmatism has a subduction-related signature. The trace elements pattern of these alkaline rocks is similar to other Miocene calc-alkaline occurrences from the magmatic arc of the Southern Central Andes. Mineral and whole

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.

    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.

    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.

    The surfaces of the body segments and appendages of male and female Dermatobia hominis (L. Jr., 1781) were studied by scanning electron microscopy with the objective of contributing to the current knowledge of the morphology of this insect. The image analyses were done with consideration of the scientific literature on morphology, ultrastructure, and insect sensory structures. A new criterion for distinguishing the sexes of this fly was observed as well as a new setiform empodium type associated with other smaller setae. Different types of trichoid sensilla were observed, as well as spinules, a type of cuticular setiform projection and a scale-like structure. The possible function of the sensilla was discussed, and sensilla with mechanosensory and chemosensory functions were found. Pilose regions that could be involved in the production and/or liberation of pheromones were encountered in the intersegmental spaces of the female abdomen. The current study of the ultrastructure of the body surface of D. hominis contributes to current knowledge of morphology, taxonomy, and sensory structures of this species.

    Full Text Available En las ciudades actuales la presencia o no de espacios públicos de recreación (parques, plazas, espacios verdes y ramblas influye en la calidad de vida de los habitantes y en consecuencia, en los niveles de sostenibilidad de la misma. Existen numerosos estudios que describen los beneficios que los mismos producen a nivel social, económico y ambiental, a la vez que refieren lo favorable que es su uso, en la salud de los habitantes. A pesar de lo extenso de la bibliografía existente no se halla unanimidad en relación a los radios de influencia de los distintos tipos de espacios públicos de recreación. Por ello, este estudio tiene como objetivo analizar y comprender los hábitos de la población de Área Metropolitana de Mendoza y así determinar si la ciudad posee la suficiente cantidad de superficie verde y si su disposición en la trama satisface a las necesidades de todos sus habitantes.

    Full Text Available En la ciudad existen una serie de procesos que comunican determinadas "visiones de mundo" a través del ejercicio de funciones organizativas y mediadoras en la arquitectura, la disposición y función de los espacios públicos, en las relaciones entre las personas y esos espacios, o entre los actores sociales y los modos de comunicarse entre éstos. Trabajaremos en este caso, sobre la relación entre un conjunto de representaciones que el campo político despliega sobre el espacio urbano. Nos centraremos en analizar cómo la ciudad se transforma a partir de ocupaciones simbólicas del espacio urbano, en el escenario de la disputa política de dos agentes opositores dentro de ese campo en Mendoza: Emilio Civit y José Lencinas, entre 1910 y 1918 aproximadamente. Veremos cómo la ideología como una de las condicionantes de producción de representaciones sociales, incide y hace variar las relaciones entre espacio y sociedad.

    Full Text Available Actualmente las acciones realizadas por los organismos de gestión que actúan sobre la planificación vial, no son suficientes para solucionar los problemas como la congestión y consumo energético, resultantes del fenómeno de movilidad y desplazamiento en núcleos urbanos. El crecimiento expansivo y la centralidad funcional generan un marcado desequilibrio entre las distintas zonas de un área metropolitana. El centro urbano, debido a su capacidad de resiliencia, consigue responder a la constante demanda de ingreso, pero sobrecargándose a la hora de cubrir las necesidades de los usuarios. Los medios de desplazamiento son los elementos conformadores de los ejes viales que dan lugar a la circulación en la ciudad y a su vez evidencian factores de impacto ambiental. Este trabajo expone una herramienta metodológica sistémica y de simple aplicación, mediante eslabonamientos de indicadores de medios de movilidad, analizados en tres periodos de tiempo, que permiten visualizar tendencias y estimaciones de condiciones futuras en relación a la movilidad urbana. Esto contribuye al desarrollo de intervenciones óptimas para la planificación vial urbana. La metodología fue validada en el Área Metropolitana de Mendoza (AMM, Argentina, en distintas escalas espaciales y temporales, utilizando datos oficiales, que contemplan los tres horarios de mayor flujo de desplazamiento.

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.

    Al estudiar la situación en Colombia durante los últimos ocho o diez años, hemos visto que es posible enfocar la Medicina de dos modos bien distintos:

    – 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.

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.

    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.

    This instrumentation grant funded the development and installation of a state-of-the-art laser system to be used for the DOE funded research at the J.R. Macdonald Laboratory at Kansas State University. Specifically, we purchased a laser based on the KMLABs Red-Dragon design, which has a high repetition rate of 10-20 kHz crucial for multi-parameter coincidence measurements conducted in our lab. This laser system is carrier-envelope phase (CEP) locked and provides pulses as short as 21 fs directly from the amplifier (see details below). In addition, we have developed a pulse compression setup that provides sub 5 fs pulses and a CEP tagging capability that allows for long measurements of CEP dependent processes.

    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.

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.)

    Full Text Available Este artigo apresenta e discute os perfis de três personagens-títulos das histórias em quadrinhos da Turma da Mônica, de Maurício de Sousa – Pelezinho, Ronaldinho Gaúcho e Neymar Jr., craques do futebol brasileiro – para evidenciar as diferentes formas de representação simbólica do futebol no imaginário midiático. A partir de um trabalho metodológico de monitoramento semiótico-discursivo das edições impressas de fevereiro de 2013 a fevereiro de 2014, selecionaramse algumas passagens para destacar as distintas nuances do conhecimento sobre o futebol veiculado nas narrativas, por meio de determinadas ocorrências sígnicas. São elas: características das personalidades dos heróis (sujeitos históricos e suas bases parafrásticas e paródicas; figuratividades do futebol – presença da bola, aspectos sociais e pedagógicos do desporto, propaganda ideológica, estereótipos e índices morais e políticos subjacentes às narrativas. Com base nessa categorização e nas teorias da linguagem de Roland Barthes e Umberto Eco, identificamos que a revista do Pelezinho, proposta mais antiga do autor, concentra no personagem grande parte do repertório cultural do futebol brasileiro dos anos 70-80, condensando questões de linguagem e comportamento, assim como a disseminação dos saberes sobre o futebol e sua pedagogia, incluindo seus desdobramentos afetivos e sociais. Já as histórias de Ronaldinho Gaúcho e Neymar Jr. têm suas propostas encomendadas a partir de temas recorrentes da agenda midiática nacional dos anos 2000, com um menor comprometimento com os saberes acerca do futebol. Por meio de enredos pouco problematizáveis, as políticas editoriais dessas duas últimas tematizam amenidades do universo infantil, engrenam campanhas ideológicas, que reforçam estereótipos e padrões morais, geralmente extraídos da factualidade  jornalística e/ou da mitologia midiático-esportiva brasileira.

    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.

    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).

    Full Text Available Different methods are used for production of bronze bearings. In terms of technical specifications, the success of each of these methods depends on the bond’s strength and in terms of economic, the production method is important. In this study, the aim is to study the strength and microstructure of steel-bronze thrust bearing bond that has been produced through the casting using pre-mold. In this study, in order to bond, the raw metals are chemically washed with sulfuric acid solution for five minutes at first. Then, the molten bronze SAE660 is cast in a structural steel S235JR pre-mold. The bond’s strength has been measured using the shear test three times; the measurement of bond’s length has been done using field emission scanning electron microscope (FESEM. The results indicate that the strength of the bond is at least 94.8 MPa and bond’s length is 0.45 micrometers. Therefore, this method was successful for trust bearing application.

  20. Deconstructing the Rosenfeld curve: Making sense of California's low electricity intensity

    International Nuclear Information System (INIS)

    Sudarshan, Anant

    2013-01-01

    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

    This study tested the hypothesis that pre-treating cortical bone with ribose would protect the rising fracture resistance curve behavior and crack initiation fracture toughness of both bovine and human cortical bone from the degrading effects of γ-irradiation sterilization. A ribose pre-treatment (1.8 M for bovine, and 1.2 M for human, in PBS at 60 °C for 24 h) was applied to single-edge notched bending fracture specimens prior to sterilization with a 33 kGy dose of γ-irradiation. Fracture resistance curves were generated with a single specimen method using an optical crack length measurement technique. The effect of the treatment on overall fracture resistance behavior, crack initiation fracture toughness, and tearing modulus was compared with non-irradiated and conventionally irradiation sterilized controls. Hydrothermal isometric tension testing was used to examine collagen network connectivity and thermal stability to explore relationships between collagen network quality and fracture resistance. The ribose pre-treatment successfully protected the crack growth initiation fracture toughness of bovine and human bone by 32% and 63%, respectively. The rising JR-curve behavior was also partially protected. Furthermore, collagen connectivity and thermal stability followed similar patterns to those displayed by fracture toughness. This paper demonstrates that the fracture toughness of irradiation-sterilized bone tissue can be partially protected with a ribose pre-treatment. This new approach shows potential for the production and clinical application of sterilized allografts with improved mechanical performance and durability. Copyright © 2016 Elsevier Ltd.

    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.

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.

El objetivo del trabajo es evaluar la eficiencia energética y las condiciones de habitabilidad de unidades de viviendas en edificios en altura. Se seleccionaron cuatro casos en la Ciudad-Oasis de Mendoza, Argentina: dos ubicados debajo y dos sobre la copa de los árboles. Se evaluaron envolventes del tipo másica y liviana. Se realizaron durante dos años mediciones higro-térmicas in situ utilizadas para validar modelos mediante el programa de simulación Energy Plus. Se estudiaron medidas de rehabilitación energética y se analizaron comportamientos térmicos y consumos de energía para climatización. Los resultados demuestran que los departamentos debajo la copa de los árboles aprovechan en verano la protección de la arboleda urbana a la radiación incidente (diferencias térmicas del orden de 4°C, y cuentan con temperaturas más elevadas en invierno (diferencias del orden de 3°C. Con la materialidad edilicia mejorada, debajo la copa se logran consumos para climatización mínimos, cercanos a un edificio de energía cero. Asimismo, las viviendas de los edificios másicos demuestran comportamientos térmicos más cercanos al rango de confort respecto a los edificios livianos.

    Full Text Available INTRODUCCIÓN: debido a los resultados clínicos no satisfactorios con instrumentaciones posteriores en los casos de tumor vertebral y a las carencias económicas de nuestros pacientes para adquirir los sistemas disponibles en el mercado, fue diseñada una prótesis de cuerpo vertebral para estabilizar la columna después de una corpectomía. OBJETIVO: describir las características estructurales y funcionales de la prótesis JR, las pruebas biomecánicas en cadáver y la técnica quirúrgica en el paciente. MÉTODOS: primeramente fue realizado un estudio anatómico detallado de los cuerpos vertebrales. Se obtuvo el diseño de un dispositivo modular, anatómico y expandible. Sus componentes una vez ensamblados hacen un implante con función dual de jaula y placa lateral expandibles. Posteriormente se efectuó un ensayo de propiedades biomecánicas en cadáver y se implantó un dispositivo en un paciente con metástasis en cuerpo vertebral. RESULTADOS: las radiografías que le fueron tomadas al cadáver, posterior a la colocación del implante, no mostraron pérdida de la fijación. Al levantar el cadáver se generaron momentos de flexión en sentido lateral con brazos de palanca de 80 cm de largo, por lo que la prótesis fue demandada en su punto más vulnerable con una fuerza de aproximadamente 588 N. Con la rotación, flexión y extensión forzadas, la estabilidad se conservó y no se visualizó movimiento del implante. Se colocó el dispositivo en una mujer de 50 años con cáncer metastásico de tiroides que afectaba L3. El dolor mejoró en el postoperatorio inmediato, así como su función motora que le permitió caminar con una columna estable e indolora por siete años. No se observó fracaso del implante. CONCLUSIÓN: la función dual de jaula y placa integrada en la prótesis de cuerpo vertebral establece una ventaja mecánica comparada con la función de la jaula y de la placa separadamente, ya que el diseño de la prótesis permite

    Full Text Available Professor Zdzisław Żygulski Jr. (1921–2015 was one of the most prominent Polish art historians of the second half of the 20th century. He treated the history of art as a broadly understood science of mankind and his artistic achievements. His name was recognised in global research on antique weapons, and among experts on Rembrandt and Leonardo da Vinci. He studied museums and Oriental art. He wrote 35 books, about 200 articles, and numerous essays on art; he wrote for the daily press about his artistic journeys through Europe, Japan and the United States. He illustrated his publications with his own photographs, and had a large set of slides. Żygulski created many exhibitions both at home and abroad presenting Polish art in which armour and oriental elements played an important role. He spent his youth in Lvov, and was expatriated to Cracow in 1945 together with his wife, the pottery artist and painter Eva Voelpel. He studied English philology and history of art at the Jagiellonian University (UJ, and was a student under Adam Bochnak and Vojeslav Molè. He was linked to the Czartoryski Museum in Cracow for his whole life; he worked there from 1949 until 2010, for the great majority of time as curator of the Arms and Armour Section. He devoted his whole life to the world of this museum, and wrote about its history and collections. Together with Prof. Zbigniew Bocheński, he set up the Association of Lovers of Old Armour and Flags, over which he presided from 1972 to 1998. He set up the Polish school of the study of militaria. He was a renowned and charismatic member of the circle of international researchers and lovers of militaria. He wrote the key texts in this field: Broń w dawnej Polsce na tle uzbrojenia Europy i Bliskiego Wschodu [Weapons in old Poland compared to armaments in Europe and the Near East], Stara broń w polskich zbiorach [Old weapons in Polish armouries], Polski mundur wojskowy [Polish military uniforms] (together with H

This prospective phase I/II study is the first to evaluate an sst antagonist, 68 Ga-OPS202 ( 68 Ga-NODAGA-JR11; NODAGA=1,4,7-triazacyclononane,1-glutaric acid-4,7-acetic acid and JR11=Cpa-c(DCys-Aph(Hor)-DAph(Cbm)-Lys-Thr-Cys)-DTyr-NH 2 )) for PET imaging. Here, we report results of the phase I component of the study. Methods: Patients received two single intravenous injections of 150 MBq 68 Ga-OPS202 three to 4 weeks apart (15 µg peptide at visit 1 and 50 µg at visit 2). At visit 1, a dynamic PET/CT scan was performed over the kidney during the first 30 min post-injection and static whole-body scans at 0.5, 1, 2, and 4 h p.i; at visit 2, a static whole-body scan was performed at 1 h. Blood samples and urine were collected at regular intervals to determine 68 Ga-OPS202 pharmacokinetics. Safety, biodistribution, radiation dosimetry, and the most appropriate imaging time-point for 68 Ga-OPS202 were assessed. Results: Twelve patients with well-differentiated gastroenteropancreatic (GEP) NETs took part in the study. 68 Ga-OPS202 rapidly cleared from the blood; the mean residence time in the blood was 2.4 ± 1.1 min/L. The organs with the highest mean dose coefficients were the urinary bladder wall, kidneys, and spleen. The calculated effective dose was 2.4E-02 ± 0.2E-02 mSv/MBq, corresponding to 3.6 mSv for a reference activity of 150 MBq. Based on total numbers of detected malignant lesions, the optimal time window for the scan was between 1 and 2 h. For malignant liver lesions, the time point at which most patients had the highest mean tumor contrast was 1 h. 68 Ga-OPS202 was well tolerated; adverse events were grade 1 or 2 and there were no signals of concern for laboratory blood or urinalysis tests. Conclusion: 68 Ga-OPS202 shows favorable biodistribution and imaging

    A magnetotelluric study along a NS profile, placed on a sedimentary basin East of Mendonza province was carried out. The objective of this study was the determination of total sedimentary thickness and the study of the Crust. For to do this, 8 magnetotelluric soundings were carried out. The Natural Electromagnetic field was measured in range of periods between 0,1 and 300 sec. In 3 soundings this range of periods was extended to 10.000 sec. using a flux-gate magnetometer. The results corresponding to 1 D modelling show in average 7,5 Km depth for the basin, including triassic and tertiary formations. The results also show variations in the thickness of the basin along the profile. The basement detach surface at 12,5 km depth is also visible in 2 soundings sites. (author). 11 refs., 2 figs

  20. Ornstein-Zernike formalism and entropy in lattice gasesTo the memory of Yasha Rosenfeld, a great scientist and human being.

    Lattice gas based models are usually discussed in terms of spin averages instead of distribution functions. As they are very useful in the study of adsorption phenomena, a density functional (DF) formalism, which would unify the discussion of both the liquid and the adsorbed phases, seems a most useful alternative. Here we present a first step in that direction by deriving the two essential components needed for any DF theory. The first one is a fully developed Ornstein-Zernike (OZ) formalism which we arrive at in two steps. The first one is the definition (through functional differentiation of the grand canonical partition function) of the distribution and correlation functions hierarchies. In the second step we find that the rigid neighbourhood of a lattice gas forces us, if an authentic DF theory is our goal and even in the grand canonical ensemble, to define N-modified distribution and correlation functions much in the same way as we have recently done when discussing DF theory in the canonical ensemble. These N-modified hierarchies of correlation functions are, indeed, linked by a full set of n-body OZ equations. The second ingredient for any DF theory is an expression for the entropy (in terms of the already discussed correlation functions) which we obtain by following previous work by us in fluids. We also generalize the compressibility contribution to the entropy by using the already derived lattice gas formalism in a way immediately translatable to liquids. In summary, we show how a deep and intimate relationship between lattice gases and fluids can be obtained if both are discussed in a DF framework with functional differentiation techniques and, therefore, we think that the beginnings of a DF theory of lattice gases are established.

    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.

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

    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.

  6. 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".

    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...

    This article is part of an occasional series profiling editors of the American Journal of Clinical Hypnosis (AJCH). William E. Edmonston was the second editor, succeeding Milton H. Erickson. His research focused on the use of conditioning paradigms and psychophysiological measures to explore a wide variety of hypnotic phenomena, leading to a "neo-Pavlovian" theory of neutral hypnosis as physiological relaxation (anesis). A longtime professor of psychology at Colgate University, he created an interdisciplinary undergraduate major in neuroscience, and was named New York State College Professor of the Year in 1988. He gave the Journal a new look, and a greater balance of clinical and experimental papers. The article also provides background on George Barton Cutten, George H. Estabrooks, and Frank A. Pattie, pioneers of hypnosis who were linked to Edmonston.

    2010-01-01

    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.

Los resultados obtenidos por la aplicación de la prueba estadística “t” student, significativamente inferiores entre la media del potencial atlético entre el 2000-2001, respecto de la década del 80 (prueba “t” 80/00 = 0,0423. No sucedió lo mismo al compararlos con las décadas del 70 y 90 que registraron entre sí valores similares en sus rendimientos atléticos (“t” 70/00 = 0,3995 y “t” 90/00 = 0,2013. 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 results obtained by the application of the "t" student statistic test are significantly lower for the average athletic potential between 2000 and 2001, compared with the decade of the 80s (t-test 80/00 = 0.0423. It was not the same when compared to the decades of 1970 and 1990, which showed similar values to each other in their athletic performance ("t" 70/00 = 0.3995 and t = 0.2013 90/00. 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.

  3. El sistema lacustre de la Formación Mollar en el depocentro triásico de Santa Clara (provincia de Mendoza, Argentina The lacustrine system of the Mollar Formation in the Triassic Santa Clara Depocenter (Mendoza Province, Argentina

    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.

    Full Text Available Durante el reposo invernal los frutales de clima templado deben estar expuestos a bajas temperaturas para satisfacer sus necesidades de frío. La disponibilidad de frío varía entre regiones y entre años, y puede ser insuficiente para los cerezos. Por lo tanto cuando se desea incorporar el cultivo del cerezo a nuevas regiones se debe conocer previamente la disponibilidad de frío invernal. Los objetivos del presente estudio fueron: desarrollar un pronóstico para estimar la disponibilidad de frío invernal y calcular la probabilidad de satisfacer una determinada demanda de frío del año en curso. Los modelos mostraron que el porcentaje de variabilidad explicado de las unidades de frío Utah modificado en las fechas de referencias (UFUM FR varía entre 50 y 87% para Junín y entre 50 y 86% para San Martín. La probabilidad que posee Junín de alcanzar el valor medio de 884 unidades de frío Utah Modificado (UFUM es 28%, mientras el valor medio de San Martín es 816 UFUM y su probabilidad es 16%. El pronóstico de frío invernal permitirá al productor evaluar los riesgos que posee su plantación de experimentar daños por falta de frío invernal y eventualmente ejecutar medidas correctivas.During the winter rest, fruit trees of temperate zones should be exposed to low temperatures in order to satisfy their chilling requirements. Chill availability varies through regions and years, and this may be insufficient for cherry trees. Therefore, when farmers want to incorporate new areas, they should be acquainted with winter chilling availability beforehand. The objectives of this study were: to develop a prognosis to estimate the amount of winter chilling and to calculate the probability of satisfying the amount of chilling requirement of any given year. Models showed that the proportion explained by modified Utah chill units at reference date (MUCU RD varied between 50 to 87% for Junín and 50 to 86% for San Martín. For Junín, the probability to reach an average value of 884 chill units Utah modified (MUCU is 28%, whereas the average value for San Martín is 816 MUCU and its probability correspond to 16%. The winter chill prognosis will allow the producer evaluates the risks which has its plantation suffer damage due to lack of winter chill and eventually implement corrective measures.

  5. Variaciones interanuales de la precipitación de verano y el rendimiento del cultivo de la vid en Mendoza

    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.

Se trata de explicitar las representaciones, intereses y saberes que han guiado las propuestas de intervención, recuperándolos como componentes constitutivos de un proceso social e histórico. A diferencia de las narrativas administrativas -que mediante la adopción de un lenguaje tecnicista y de nociones como la de hábitat, terminan por naturalizar, neutralizar y deshistorizar los conflictos políticos implícitos en la construcción de territorios étnicos- enfocamos los mecanismos de intervención sobre los indígenas como una forma de territorialización, revisando críticamente la pretendida mirada neutra y objetiva del aparato administrativo-judicial, apoyada en representaciones atemporales.The objective of this work is to analyze, through approach to one ethnography of the administrative processes, the plot of state devices that have operated in the allocation of earth to the adscript indigenous like Huarpes and that operate contemporarily in the definition of their territorial rights.

    2016-03-01

    Due to the low spatial and temporal resolution of the available measurements, highly variable air concentrations of several POPs have been observed in Latin American and Caribbean countries. This paper presents a high resolution spatially disaggregated atmospheric emission inventory for selected POPs in order to assess the environmental fate of some of these compounds in a finer resolution. As study case we estimated releases to air of POPs in a typical mid-size urban conglomeration in Argentina. Inventoried compounds were total polychlorinated biphenyls (PCBs, total polybrominated diphenyl ethers (PBDEs, total dichlorodiphenyltrichloroethane (DDT on a sum basis, hexachlorobenzene (HCB and dioxins and furans (PCDD/Fs, for which emissions were estimated in 0.92 kg/year, 1.65 kg/year, 4.2E−02 kg/year (total sum of congeners, 0.86 kg/year and 4.4E−02 kg/year respectively, values that are in accordance with the geographic and economic context. Although emitting sources are quite varied, there are very clear trends, particularly in relation to open burning of municipal solid waste and agrochemical use as major contributors. Overall, the inventory provides valuable data for the analysis of the heterogeneity of POP emissions and the necessary inputs for air quality modeling.

  16. 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)

    1991-10-01

    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.

    2015-06-01

    Full Text Available Pemphis acidula Forst. (Lythraceae has been reported herein with locality data after a lapse of 91 years from Andaman Islands. This re-discovery is significant as P. acidula has not been added to the mangrove flora of India in many important national and international status reports. This species is characterized by its narrowly elliptic to lanceolate leaves that are densely covered with silky hairs on both surfaces, crumpled white petals, capsule with circumscissile dehiscence and winged seeds. Further, new morphological discoveries viz., tetramerous and pentamerous flowers were reported in the present study in contrast to the perfect hexamerous flowers reported elsewhere. Since P. acidula is sparsely distributed, location-specific conservation strategies should be adapted in order to prevent its local extinction from the Islands. In addition, exploratory surveys are imperative particularly in calcareous rocky habitats for authenticating the wider distribution of such rare species.

    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.

  14. From philosopher to psychologist: the early career of Edwin Ray Guthrie, Jr.

    Science.gov (United States)

    Clark, David O

    2005-08-01

    Edwin R. Guthrie rose to prominence as a psychologist in the 1930s. His theoretical outlook was behavioristic. This approach came from his conviction that an objective method could be applied to a scientific treatment of mind. Prior to becoming a psychologist, he was a philosopher of mathematics. Guthrie was initiated into psychology by Stevenson Smith, from whom he learned a psychology of adjustment informed by comparative research, Columbia functionalism, and clinical psychology. Guthrie's first step into psychology was in collaboration with Smith on Chapters in General Psychology (S. Smith & E.R. Guthrie, 1921). To synthesize their own unique position on learning from the contemporary theory and research, they used the principle of association. This articles focuses on Guthrie's origin and his development into a learning theorist.

    Wamser, Christian A.; Wamser, Carl C.

    1996-07-01

    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.

    The ultrastructure of the mouthparts of Dermatobia hominis was studied using scanning electron microscopy. The morphological characteristics of the segments, articulations, sensory organs, and pilose covering are described. Mechanoreceptors of the long trichoid sensillum and smaller trichoid sensillum types were observed, as well as labellar gustatory receptors of the basiconic sensillum type, which differed between the sexes. These observations are discussed with reference to the current literature on the morphology and sense organs of dipteran mouthparts, and the prevailing view that the adult mouthparts of this species are non-functional is challenged.

  4. Faith 7 L. Gordon Cooper, Jr., and the final Mercury mission

    CERN Document Server

    Burgess, Colin

    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.

    2016-01-01

    Colin Burgess offers a comprehensive yet personal look at the 1962 orbital mission of Wally Schirra aboard the spacecraft Sigma 7, the first book about this popular pioneering astronaut which explores his entire life and accomplishments. This continues the author's attempt to fully document the record of Project Mercury's pioneering early phase of the Space Age.   Schirra’s pre-NASA life is examined, as well as his training as a NASA astronaut and for his Mercury MA-8 flight. The 6-orbit flight of Sigma 7 is fully covered from its origins through to the spacecraft’s safe recovery from the ocean after a highly successful Mercury mission. Schirra’s participation on the Gemini 6 and Apollo 7 missions is also told, but in brief, and the book also relates his post-NASA life and activities through to his passing in 2007. The Mercury Seven occupy a unique spot in the history of human spaceflight, and Schirra is at last given his due as one of the contributing astronauts in this painstakingly researched...

    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.

    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

    This year was the fifth 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 (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 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 sixty-seven proposals were submitted for unclassified research and twelve proposals for research of a programmatic interest to the Laboratory; six experiments in support of the LANSCE research program were accomplished during the discretionary periods.

    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.

    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.

  18. The impact of tree species selection on the thermal comfort of urban canyons in arid zones: The case of Mendoza, Argentina

    Full Text Available Increasing urban vegetation is known worldwide to be a strategy for mitigating urban heat islands. This study evaluates how the energy balance of an urban canyon is affected by different combinations of urban morphology, tree species features, and building density. The thermal behaviors of 16 urban canyons, 16, 20 and 30m in width, located in areas of high and low building density, with three predominant types of tree species in the city were monitored in summer, in addition to one tree-free case. The COMFA energy balance model was used to assess the degree of habitability of open spaces. The results show that the appropriate selection of tree species is the key to maximizing the energy efficiency and habitability of urban spaces in areas of low building density in the city.

    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.

    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 El paisaje rural del departamento de Maipú se caracteriza por una heterogeneidad integradora y un dinamismo activo, propio de la actividad productiva agrícola. e ste posee elementos que clarifican su carácter, pero otros que contribuyen a su banalización. 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.

    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.

  10. 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.

    2005-12-01

    Full Text Available A new methodology for the construction of J-R curves for ductile materials, based upon the analytical integration of the P-v 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 as C&C, reproduces quite well the experimentally obtained P-ν, Δa-νand J-Δa curves. The results suggest that the amount of stable crack growth in a ductile material follows a power law behavior 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-Δarelations.

    Se presenta una nueva metodología de construcción de la curva J-R para materiales dúctiles, obtenida por integración analítica de la relación P-v. Esta metodología está basada en los "Formatos" "Común" y "Conciso", y en el postulado de una ley de crecimiento de grieta, que relaciona el monto de avance estable con el desplazamiento plástico. El modelo desarrollado, denominado C&C, reproduce muy bien las curvas obtenidas experimentalmente de los tipos P-ν, Δa-ν y J-Δa. Los resultados generados permiten sugerir que el crecimiento estable de grieta en un material dúctil obedece una relación de tipo potencial en su dependencia con el desplazamiento plástico. Esta metodología, puede utilizarse para evaluar las condiciones de inestabilidad, mediante el adecuado tratamiento analítico de las relaciones P-ν y J-Δa.

    International Nuclear Information System (INIS)

    Aurich, D.; Wobst, K.; Krafka, H.

    1989-01-01

    This paper is concerned with experimental tests on the transferability of the J-values for the crack initiation and the stable crack growth from specimens to structures. To this purpose, tests were made on CT25 specimens, on centre cracked or centre notched panels (CCT, CNT), on double edge cracked panels (DECT) as well as on a pressure vessel with different axial through wall flaws. The aims of the tests were to determine the J-values for the initiation of stable cracks J i and the crack growth resistance curves for the specimens and the pressure vessel. The intention was to clarify which kind of specimen and which specimen geometry - in relation to the structure behaviour - would result in conservative J R -curves. The material to be tested was a high strength steel of the German standard type StE 460. The random tests were carried out at 25±2 0 C. A comparison of the J R -curves shows that the evaluation of the crack growth resistance behaviour of the pressure vessel compared with the results of the CCT and CNT specimens, is non-conservative. The corresponding results of the CT25 and DECT specimens differ only slightly in the investigated crack growth range; they are in the scattering range of the results of the pressure vessel.

    The high energy physics group at the University of South Carolina, under the leadership of Profs. S.R. Mishra, R. Petti, M.V. Purohit, J.R. Wilson (co-PI's), and C. Rosenfeld (PI), engaged in studies in "Experimental Particle Physics." The group collaborated with similar groups at other universities and at national laboratories to conduct experimental studies of elementary particle properties. 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. Purohit and Wilson participated in the Ba

    The book is substantially free of errors and I found only a handful of grammatical oversights (pages 152, 165, 479). Most problematic are a confusion between a and [a] (page 198), a definition of mass spectrometry involving fragmentation by radiation (glossary G4), a typo in a model-building exercise on the construction of 2,3-dibromobutane (page 218), and the implication that multiphoton processes do not occur (page 516). A carbon NMR spectrum (page 534) is drawn so as to suggest that J is not constant and, while described in words, the phrase "n+1" is surprisingly absent. Lastly, I do not agree that the sawhorse diagram (page 54) is entirely self-evident to students. But, in proper perspective, these are all minor points. This latest edition, as those before it, ably and enthusiastically illustrates the wide range, deep uniformity, and undeniable centrality of organic chemistry in a molecular understanding of the architecture and applicability of topics ranging from buckyballs to biochemistry. Considerable thought has gone into illuminating the essentials of organic structural change and in presenting these concepts and connections clearly and simply. This text has much to recommend it as an excellent choice for the short or even the not-so-short course.

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.

    Throughout the centuries, anatomists attempting to denominate the new structures they discovered have found inspiration in the civilization of ancient Rome and the clothing worn by its citizens. This aricle presents the origins of seven neuroanatomical terms, fimbria, velum, funiculus, lemniscus, corona, splenium, and cingulum, inspired by the clothing and jewellery of Roman women and the military attire of Roman soldiers. Thus, through their apparel, the Romans influenced the Terminologia Anatomica and "clothed" the structures of the brain and spinal cord, making them immortal. Clin.

    In response to limitations in access to subspecialty care, I present personal observations and suggestions related to education of future pediatricians regarding development of critical thinking skills, care of complex and chronically ill patients, development of empathy, and restoration of responsibility that may help ameliorate this serious problem. Toward this end, I also offer 1 approach, a 24/7 telephone consultation network, for enriching interaction of primary care providers (PCPs) and subspecialists who can potentially provide rapid access to needed advice, reduce demand for subspecialty appointments, bolster decision-making and expertise, and realign resources with need. Data were obtained from 579 requests by PCPs for telephone consultation by subspecialists in 8 areas (including child psychiatry). Of calls, 27% took <5 minutes and 79% took 5 to 15 minutes. Of calls, 28% resulted in a clinic visit; 8% prompted hospital transfer, hospital admission, or referral to an emergency department; and the remaining 64% resulted in continued management by PCP with reinforcement of the plan. Assuming most inquiries would have resulted in referral to a subspecialist were there no telephone consultation, we estimated that 70% (8+64%) of consultations realigned resources with need, resulting in large saving of unnecessary clinic visits, travel, expense to families, lost days at work, or missed school. Development of rapid telephone consultation networks could provide increased access to care for those children in greatest need, use limited resources more efficiently, foster collegial and productive relationships between medical providers, and increase expertise of PCPs and subspecialists.

    Full Text Available Nodules of the tropical warble-fly (Dermatobia hominis in Canchim cattle breed ranging from24 to 36 months of age were counted in males and females, to study its epidemiology in the São Carlos region. The nodules of the warble-fly were counted in groups of 15 animals in the left side every 14 days. The counts started in January, 1982 and ended in December, 1983. The heaviest warble-fly infestations were observed in February, September, October and December which represent the frequencies of 14.5%, 17.5%, 17.5% and 9.7%, respectively. The lowest warble-fly infestations were observed in July and August with 1.2% and 0.9% respectively. During the months of January, March, April, May, June and November, the animals showed an intermediary warble fly count being of 5.8%, 4.5%, 7.5%, 7.4% and 7.7%, respectively. The highest frequencies of warble-fly nodules were observed during the warm and humid period, while the lowest frequencies were found during the cold and dry seasons.

    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.

    2010-12-01

    Full Text Available We report an interspecific combat involving the tree frog Hypsiboas faber and the toad Rhinella pombali in southeastern Brazil. Since the observation occurred after the beginning of the interaction, either one of the species may have started the fight. In general, intra-specific combats are more common for species in which the male is as large, as or larger than, the female, as observed in Hypsiboas faber. Thus, the male tree frog might have confused the toad with a conspecific opponent. On the other hand, bufonid males can use active searching for females, sometimes clasping other males or objects. Therefore, the toad might have clasped the male tree frog and it was this that provoked the subsequent wrestling.

    Our study was conducted to further investigate the single-dose approach of hepatitis A vaccination, while providing supportive data on the flexibility of booster administration. Participants received at least one dose of Avaxim 80U Pediatric at 11-23 months of age, and they will be followed for 10 years. We report here the fourth and fifth years after the first vaccination. Group assignment was based on whether the children received 1 dose and no booster during the study (Group 1) or 2 doses and no further booster (Group 2). Anti-HAV antibody concentrations were assessed at each annual visit. Of the 546 initial participants, 441 (80.8%) and 412 (75.5%) were followed up 4 and 5 years after vaccination, respectively. Of the 411 subjects evaluable at Year 5, 318 had received one vaccine dose and 85 had received two. Seroprotection rates were still high in Group 1 (99.7%) and in Group 2 (100%) 5 years after one or two doses of Avaxim 80U Pediatric, correspondingly. Anti-HAV geometric mean concentrations decreased in both groups compared to what they were 3 years after vaccination, while remaining well above the 10 mIU/mL threshold 5 years after vaccination. The highest concentrations were found in the children who received 2 vaccine doses. Hepatitis A humoral immunity induced by a single dose of inactivated hepatitis A vaccine can persist for at least 5 years in a paediatric population. The study results also support recommendations in favour of a flexible time window for booster vaccination. © 2014 The Authors. Journal of Viral Hepatitis Published by John Wiley & Sons Ltd.

    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 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.

    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.

    The field notes of J. R. Slevin written during the expedition of the California Academy of Sciences to the Galapagos Islands in 1905-1096 contain previously unavailable data on the marine turtles of the eastern Pacific. 'Land basking' by green turtles in Galapagos was predominately, if not exclusively, a female behavior. These terrestrial emergences were not concentrated in the major reproductive season of Galapagos turtles. Female Chelonia were also collected on shore during daylight hours on Socorro Island southwest of Baja California, Mexico. Chelonia, green turtles, were observed to feed on seaweed, the leaves and shoots of mangrove trees, and the leaves of another unidentified shoreline shrub. Comparative data on the gonads of dark and yellow turtles indicated that the latter did not breed in Galapagos during Slevin's stay. Lepidochelys olivacea, the olive ridley, was recorded in Galapagos waters and fed on fish eggs

    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.

    This paper presents a detailed theoretical discussion of destructive narcissism in relation to Freud and Rosenfeld and later theorists. In destructive narcissism, the destructiveness is itself idealised and overrides "the vital functions which serve the purpose of self-preservation" (Freud, S., 1914, "On narcissism" S.E. 14: 87)--a feature which…

  13. Water-like anomalies in the core-softened systems: Dependence on the trajectory in density-temperature plane

    International Nuclear Information System (INIS)

    Fomin, Yu.D.; Ryzhov, V.N.

    2011-01-01

    We show that the existence of the water-like anomalies in kinetic coefficients in the core-softened systems depends on the trajectory in ρ-T plane along which the kinetic coefficients are calculated. In particular, it is shown that the diffusion anomaly does exist along the isotherms, but disappears along the isochors. We analyze the applicability of the Rosenfeld entropy scaling relations to the systems with the core-softened potentials demonstrating the water-like anomalies. It is shown that the validity of the Rosenfeld scaling relation for the diffusion coefficient also depends on the trajectory in the ρ-T plane along which the kinetic coefficients and the excess entropy are calculated. In particular, it is valid along isochors, but it breaks down along isotherms. -- Highlights: → We analyze the anomalies in kinetic coefficients in the core-softened systems. → We show that the anomalies depend on the trajectory in density-temperature plane. → The applicability of the Rosenfeld entropy scaling to these systems is analyzed. → The validity of the Rosenfeld scaling relation also depends on the trajectory.

    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.

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.
