Strategies, Programs and Projects 2008 of the Astrophysical Group "SPACE-Universidad Nacional Mayor De San Marcos, Peru" - Preparing for the IYA2009  

NASA Astrophysics Data System (ADS)

We present a review of our efforts to introduce astronomy as scientific career in Peru, showing how our astronomy outreach programs have been one of the most important keys to reach our national astronomical scientific goals, remarking the crucial role that the celebration of the IYA2009 must play, in order to promote PhD programmes in astronomy in developing countries. We show the importance of the creation of the Seminario Permanente de Astronomía y Ciencias Espaciales (SPACE) in the Universidad Nacional Mayor de San Marcos, as an academic scientific and cultural center in Peru, to support our 26 years-old "Astronomical Fridays” which are addressed to wide range of public, from schoolchildren to scientists. We also show how important was to rediscover our ancient astronomical cultural past of Incas in order to promote the construction of a Astronomical Center located near Cusco city over 4000 meters above sea level, which includes a tourist-educational observatory, a scientific optical observatory and a solar radio observatory.

The vibrational modes of a C molecule irradiated with ultrafast laser pulses are studied, using a tight binding approach with variable occupations. It is shown that for the same level of electronic excitation, measured through the electronic temperature, each mode suffers a distinct softening. Excited trajectories below and above the damage threshold, are examined. It is shown that the bond breaking processes and the ulterior fragmentation might be described in terms of the activation of softened vibrational modes; and that the changes in frequency can be dramatically larger than those estimated with the isothermal model.

Speckle Interferometry and Speckle Photometry of Binary Stars at Telescopes of Observatorio Astronomico Nacional  

NASA Astrophysics Data System (ADS)

The Observatorio Astronomico Nacional (OAN) is a facility of the Instituto de Astronomía of the Universidad Nacional Autónoma de México (IA-UNAM). There are two astronomical sites where the four telescopes are mounted: one site is located at San Pedro Mártir (OAN-SPM), Baja California, and the second one at Tonantzintla (OAN-T), near Puebla, Mexico. These telescopes can be effectively used for speckle interferometric and for speckle photometric measurements of binary and multiple stars with the Rayleigh resolution limit R = 1.22 ?/D. Regular speckle interferometric measurements of binary stars have been made with telescopes of the OAN since 2008. In 2011 we start speckle photometric measurements in three colors (V,R,I). In 2012 two more spectral bands (U,B) were added.

Exoplanet Surveys at Universidad de Chile  

NASA Astrophysics Data System (ADS)

We present and highlight the first results of the three main exoplanet surveys we are currently conducting at Universidad de Chile: CHEPS, Red Giant Exoplanets (radial velocity), and TraMoS (transit lightcurves). We have several interesting candidates at the Calan-Hertfordshire Extrasolar Planet Search (CHEPS) project, which is aimed at searching for the currently missing southern bright transiting planets at a few m/s radial velocity precision. Using the same technique, we are also characterizing the planetary population in a constrained sample of Red Giant stars. The Transit Monitoring from the South (TraMoS) project is aimed both at improving transit parameters and at detecting any kind of lightcurve variability from several known southern exoplanet systems.

The Observatorio Astronómico Nacional - Tonantzintla: Site Evaluation  

NASA Astrophysics Data System (ADS)

The objective of this contribution is to present some results of an evaluation on the local conditions at the site that were considered in order to propose that the Observatorio Astronómico Nacional, Tonantzintla, (OAN-Tonantzintla) become a National Facility for Astronomy Education. The evaluation included a quantitative diagnostic (CCD photometry) on the quality of the local sky. The attributes of the 1-m telescope, the current instrumentation and a well planned upgrading that includes new instrumentation is considered at the basis for a successful transition maintaining the attractiveness of the site for astronomy education. A 3-year upgrading program actually in progress at UNAM is providing funding for that purpose. Physics and astronomy programs at college and graduated levels at UNAM will benefit from this, yielding clear connections among astronomy researchers and educators and students at various levels. Although the OAN-Tonantzintla faces the danger of deteriorating its sky conditions, we are maintaining awareness of the night sky characteristics in long-term monitoring campaigns and encouraging the local authorities to find alternative solutions to this problem.

[Description of assessment processes at the Medical School of the Pontificia Universidad Católica de Chile: a ten year experience].  


Globalization of health care seems to be irreversible and beyond cultural differences and local realities; consequently, medical education needs to have a common set of core principles or standards that may be applied worldwide. The aim of participating in assessment processes is to guarantee that medical education takes place in a sufficiently rich environment to promote extensive academic purposes. The Medical School of the Pontificia Universidad Católica de Chile (PUC) participated in three assessment processes that included three stages: internal assessment, external assessment, and accreditation judgment. Two of these assessments were voluntarily carried out following the standards set by the Liaison Committee on Medical Education-LCME, and they took place in 1997 and 2007. The other assessment was based on standards set by the Chilean accrediting organism, the National Committee for Undergraduate Program Accreditation (Comité Nacional de Acreditación de Pregrado-CNAP) and took place in the year 2001. In all three experiences, internal assessment was the most enriching stage, stimulating refections among students and teachers in order to recognize areas of strengths and weaknesses. External assessment processes, especially those based on international standards, are very important for the institutional and program development of Medical Schools. The PUC Medical School on its whole learnt how to carry out an assessment process and was able to improve several weaknesses without pressure, moving from quality assurance to quality enhancement. The present paper analyzes the major challenges involved in an external assessment process. PMID:21140066

Speckle Interferometry at the Observatorio Astronómico Nacional. IV  

NASA Astrophysics Data System (ADS)

We present speckle interferometric measurements of binary stars performed during September and October of 2009 with the 2.1 m telescope of the Observatorio Astronómico Nacional at SPM (Mexico). We report here the results of 200 measurements of 196 pairs with a primary limiting magnitude of V = 12.3. The measured angular separations range from 0".115 to 5".26. Ninety seven pairs have separations less than 1". The mean error in separation is 0".03 and 1°.5 in position angle. The usual 180° ambiguity was corrected for a majority of position angles by comparison with observations performed by other observers.

The development of the Heliometer of the Observatório Nacional  

NASA Astrophysics Data System (ADS)

The Observatório Nacional at Rio de Janeiro has developed a new heliometer to perform accurate measurements of the solar diameter. The equipment makes use of split parabolic mirrors, rather than split achromatic lenses as objective. In its first campaign this reflector heliometer generated a few thousands of images of the Sun through which we evaluate the precision of the solar diameter measurements as been 5 mas. The mechanical and thermal stability of the instrument is guaranteed by the use of a telescope tube manufactured in carbon fiber. The tube firmly holds the heliometric mirrors and the CCD camera that collects the images. The perfect lodging between the two half-mirrors over its supporting plate defines the angular instrumental separation between the two images of the sun. The heliometric mirrors and supporting plate have been made in ceramic material in order to ensure the stability of the optical configuration and to maintain the two images of the solar disk displaced by a fixed angle in relation to each other. To verify the stability of the instrument we designed the procedures of collimation and comparison. The collimation consists of using the heliometer for measuring the diameter of an artificial solar image specifically created for this purpose. The comparison is performed by measuring the residual unfold of a punctual image after been unfold by two opposed heliometers. The heliometric approach allows the measurement of the solar diameter at any heliolatitude and can be undertaken as often as desired. Computer programs have been developed for automated image acquisition and analysis. The optical and mechanical design has been performed by using 3D computer aided design software.

The orchid-bee faunas (Hymenoptera: Apidae) of 'Parque Nacional do Monte Pascoal', 'Parque Nacional do Descobrimento' and three other Atlantic Forest remnants in southern Bahia, eastern Brazil.  


The orchid-bee faunas of 'Parque Nacional do Monte Pascoal', 'Parque Nacional do Descobrimento' and three other Atlantic Forest remnants ranging from 1 to 300 ha in southern Bahia, eastern Brazil, were surveyed. Baits with seventeen different scents were used to attract orchid-bee males. Four thousand seven hundred and sixty-four males belonging to 36 species were actively collected with insect nets during 300 hours from November, 2008 to November, 2009. Richness and diversity of orchid bees found in this study are the highest ever recorded in the Atlantic Forest domain. Eufriesea dentilabris (Mocsáry, 1897) and Eufriesea violacea (Blanchard, 1840) were collected at the 'Parque Nacional do Monte Pascoal', the first record of these species for the state of Bahia and the northernmost record for both species. Females Exaerete dentata (Linnaeus, 1758) were also collected at 'Parque Nacional do Monte Pascoal' and old records of Eufriesea aeneiventris (Mocsáry, 1896) in this area makes this site the richest and most diverse concerning its orchid-bee fauna in the entire Atlantic Forest and similar to areas in the Amazon Basin.

Experience the magic of light and color: outreach activity by Universidad del Valle student chapter  

NASA Astrophysics Data System (ADS)

During 2007, the Universidad del Valle Student Chapter presented a proposal for developing an educational outreach activity for children from an underprivileged zone to the Optical Society of America Foundation (OSAF) and to SPIE. The activity was carried out jointly by OSA and SPIE Universidad del Valle Student Chapters in the hillsides of Santiago de Cali, in a zone known as "Pueblo Joven" during 2008. It was aimed to boys and girls with ages between 8 and 13 years and was called "Experience the magic of light and color". The main purpose was to bring the children some basic concepts on optics and to encourage them to explore science through optics. The Universidad del Valle Student Chapters designed a series of talks and practical workshops where children participated in hands-on experiments that easily explain the fundamental concepts of light phenomena. Afterwards the children presented their achievements in a small science fair offered to the community and tried to explain in their own words what they learned and built. In this work, we present the most successful experimental designs and the educational standards we tried to develop with this activity.

[The Bernardino Álvarez Farm Hospital and Farm School: antecedents to Instituto Nacional de Neurología y Neurocirugía].  


By 1960, México's Manicomio General (General Asylum) could no longer fulfill the functions for which it was created so implementation of the so-called Castañeda Operation began, an initiative designed to close down and relocate psychiatric patients to other institutions. At that time, Dr. Manuel Velasco-Suárez was in charge of the General Direction of Neurology, Mental Health and Rehabilitation, and planned to create the Institute of Neurology on a site he already possessed for its construction. The Asylum was a dependency of the aforementioned Direction and Velasco- Suárez decided that some patients at the Castañeda could be moved to the old hacienda house that stood on that terrain. Thus was born the Bernardino Álvarez Farm Hospital. A year later, in 1961, the Farm School for the Weak-Minded, also named Bernardino Álvarez was established there as well. This paper examines the history of these two institutions as antecedents to the Instituto Nacional de Neurología y Neurocirugía. PMID:24687360

Ambient Dose Equivalent measured at the Instituto Nacional de Cancerología Department of Nuclear Medicine  

NASA Astrophysics Data System (ADS)

Ambient dose equivalent values were determined in several sites at the Instituto Nacional de Cancerología, Departmento de Medicina Nuclear, using TLD-100 and TLD-900 thermoluminescent dosemeters. Additionally, ambient dose equivalent was measured at a corridor outside the hospitalization room for patients treated with 137Cs brachytherapy. Dosemeter calibration was performed at the Instituto Nacional de Investigaciones Nucleares, Laboratorio de Metrología, to known 137Cs gamma radiation air kerma. Radionuclides considered for this study are 131I, 18F, 67Ga, 99mTc, 111In, 201Tl and 137Cs, with main gamma energies between 93 and 662 keV. Dosemeters were placed during a five month period in the nuclear medicine rooms (containing gamma-cameras), injection corridor, patient waiting areas, PET/CT study room, hot lab, waste storage room and corridors next to the hospitalization rooms for patients treated with 131I and 137Cs. High dose values were found at the waste storage room, outside corridor of 137Cs brachytherapy patients and PET/CT area. Ambient dose equivalent rate obtained for the 137Cs brachytherapy corridor is equal to (18.51+/-0.02)×10-3 mSv/h. Sites with minimum doses are the gamma camera rooms, having ambient dose equivalent rates equal to (0.05+/-0.03)×10-3 mSv/h. Recommendations have been given to the Department authorities so that further actions are taken to reduce doses at high dose sites in order to comply with the ALARA principle (as low as reasonably achievable).

Development and first year of results from the Heliometer of Observatório Nacional  

NASA Astrophysics Data System (ADS)

Recent research on global climate changes points to three distinct sources of climate disturbance: anthropogenic; natural changes in the oceans and atmosphere; and irregularities in the solar cycles. One of the most direct ways to survey an exogenous component of the climatic variability is through the measurement of variations in the diameter and shape of the solar disk. At Observatório Nacional/MCTI, Rio de Janeiro, after several years of diameter observation using a CCD Solar Astrolabe, these measurements are now performed by a state-of-the-art Solar Heliometer. The heliometric method is one of the most successful techniques to measure small variations of angles. Its principle has been used for the latest space borne astrometric missions, aiming to milli-arcsecond precision. The success of this method relies in the fact that it minimizes the dependence of angular measurements to the thermal and mechanical stability of the instrument. However in the classic heliometer the objective is split into two halves to which is applied a linear displacement along the cut, thus still leaving room for a residual dependence with the focus, due to non-concentricity of the beams of the two images. The focus variation, as well as the effects brought by the large temperature variations during solar observations, was tackled in the Solar Heliometer by having all optical elements and their niches made on CCZ, and the telescope tube on carbon fiber, both materials of negligible thermal coefficient. Additionally, the measures are made perpendicular to the separation direction and the plate scale can be known at every time from the solar motion itself. We present the results from the first year of measurements, in special exploring the upheaval of solar activity on late 2011.

The origin of oriented lakes in the Andean foreland, Parque Nacional Torres del Paine (Chilean Patagonia)  

NASA Astrophysics Data System (ADS)

The Parque Nacional Torres Del Paine and surrounding area in the Magallanes foreland basin in Chilean Patagonia is the site for numerous lakes fed by glaciers and rivers in the Andean highlands to the west. The lakes are elongate and have conspicuously systematic orientations. We hypothesize that the origin of the oriented lakes lies in the fault system, composed of a right-lateral strike-slip fault set oriented 58° from north, a left-lateral strike-slip set oriented 87°, and a thrust fault set oriented 167°, that exists within the underlying rocks. To test this hypothesis quantitatively, we determined the shape and orientation of the lakes by fitting each lake with an ellipse of appropriate aspect ratio, and later with multiple ellipses consistent with the composite geometry of some lakes. We then examined the faults in the area in terms of their kinematics, orientation and distribution. The distribution of lake orientations showed three distinct groups which appear to correspond to the three main fault groups. For lakes fitted with multiple ellipses, the difference in means between the right-lateral, left-lateral, and thrust faults and their corresponding groups of lakes are 3.05°, 1.57°, and 5.17°. Using a Kolmogorov-Smirnov (K-S) statistical test to compare the orientations of faults with respect to the lakes suggests that there is not a strongly significant difference between the fault orientations and the corresponding lake groups. These results indicate that the faults have a profound control on the orientation, shape, and distribution of the lakes. We attribute this to faults and their damage zones being weaker and therefore prone to a faster rate of erosion, and to stress perturbations associated with discontinuous faults resulting in localized high density fracturing and surface subsidence. These results have implications for lake and drainage system morphologies in other foreland basins along the Andes and other similar settings.

[The Universidad de Buenos Aires in the 1970s: analysis of the press release expressing solidarity with Rodolfo Puiggrós].  


This article reconstructs the historical context surrounding the emission of a press release by authorities of the Universidad de Buenos Aires, expressing their solidarity with historian and university rector Rodolfo Puiggrós after his resignation. In his term, Puiggrós attempted to fuse the institution's scientific and technological plans with the new development model initiated by Héctor Cámpora and the Peronist movement in 1973. The article makes reference to the project of university transformation promoted by Puiggrós, combining the ideological traditions of Marxism, reformism, and nationalism. A few key points, useful for analyzing the reasons behind Puiggrós's resignation, are presented, and the arguments highlighted within this press release, published by Office of Media and Communications on October 5, 1973, are discussed.

[Theses on hepatitis at the Faculdade de Medicina of the Universidade Federal do Rio de Janeiro, 1837-2000].  


An inventory of the theses on hepatitis of the Faculdade de Medicina of the Universidade Federal do Rio de Janeiro between 1837 and 2000 is presented. The analysis indicates the potential and limits for discussion of the evolutionary framework of scientific knowledge on these health problems in Brazil. The theories are also discussed in light of their scientific reference points and the technological and social changes that influenced them. The landmarks in medical education and knowledge about hepatitis are identified and categorized, considering that the theses reveal at the very least the state of the art on the subject. The study makes it possible to explore the foundations upon which the scientific knowledge on hepatitis were built and indicate possibilities for research in the reconstruction of scientific knowledge of other health problems.

[Voice disorder clinic in the speech therapy outpatient unit at "Hospital das Clínicas da Universidade Federal de Minas Gerais"].  


This study set out to describe the profile of the patients with voice complaints and/or alterations who were attended between July 2003 and December 2006 at the speech therapy outpatient unit of "Hospital das Clínicas da Universidade Federal de Minas Gerais." This was analyzed according to age, sex, profession, schooling, origin, treatment performed and factors that interfere in medical care evolution. This was a retrospective study based on the analysis of the recorded data of the individuals according to a specifically prepared Protocol. The results showed that the individuals included in this study were predominantly young women, referred by a specialist from Belo Horizonte, who do not work and also have incomplete elementary school education. Attendance of those patients was on an individual basis, and almost half of them were discharged by the speech therapist. The elderly patients, who have functional or psychogenic dysphonia and a neutral or wheezy type of voice, showed a close correlation with the discharge rate by speech therapist. The younger individuals with organo-functional dysphonia bore a statistical correlation with abandoning treatment. The individuals who eventually abandoned treatment did not bear any correlation with the crossed variables. PMID:21808900

The Museum of History "Hospital Nacional de Clínicas", from the National University of Cordoba, República Argentina, it's charged with the knowledge continuity of the Health Science, in time and space. Its guiding motto says: "I'll be a shield to stop the wind that wants to erase the imprint of men that shaped the history of the School of Medical Sciences by their work." To accomplish the tasks, general and particular objectives were settled. The Museum has a Library divided in three sections: Classical, Contemporary and Virtual. It counts with a specialized Information and Documentation Centre. Courses about different topics are given as well as the course of History of Medicine for Grade and post grade careers, completing with humanistic contents, the students education exclusively scientific and technical. For high school and Bachelor students there is a program called: "Education - Apprenticeship strategies at the Museum". These strategies are arranged to fit the programmes and levels of formal education for educational institutions. The heritage of the Museum consists of more than a thousand apparatus and tools that served the research and instruction at the different professorships of the School of Medical Sciences. Many of them obsolete they allow us to understand the evolution of science and technique, within the broad field of Health Science, since the creation of the School of Medical Sciences in 1877.

[Eccrine Porocarcinoma: clinical-pathological study of 19 cases in the Instituto Nacional de Enfermedades Neoplásicas, Lima - Peru].  


In order to describe the clinical-pathological characteristics of the cases of Eccrine Porocarcinoma (EP) found in the Instituto Nacional de Enfermedades Neoplásicas (INEN), a cross-sectional study was carried out, including all EP cases recorded between 1998 and 2009. A revision of the clinical-pathological records indentified and a new reading of the pathology slides of the cases found were performed. 19 EP cases were found, the median age of which was 64 years (range: 37-98). EP was primarily found on male patients (57.9%) and was most commonly located on the foot (21.1%), followed by the head, thorax and thigh (15.8%, respectively). In one case, EP was located on the gluteal region, and showed an unusually invasive behavior and rectal involvement. We conclude that EP is a rather uncommon entity in Peru. Its most common location is on the foot and it affects mostly male patients for the most part. PMID:24100819

Teaching Planetary Sciences at the Universidad del País Vasco in Spain: The Aula Espazio Gela and its Master in Space Science and Technology  

NASA Astrophysics Data System (ADS)

Planetary science is a highly multidisciplinary field traditionally associated to Astronomy, Physics or Earth Sciences Departments. Spanish universities do not generally offer planetary sciences courses but some departments give courses associated to studies on Astronomy or Geology. We show a different perspective obtained at the Engeneering School at the Universidad del País Vasco in Bilbao, Spain, which offers a Master in Space Science and Technology to graduates in Engineering or Physics. Here we detail the experience acquired in two years of this master which offers several planetary science courses: Solar System Physics, Astronomy, Planetary Atmospheres & Space Weather together with more technical courses. The university also owns an urban observatory in the Engineering School which is used for practical exercises and student projects. The planetary science courses have also resulted in motivating part of the students to do their master thesis in scientific subjects in planetary sciences. Since the students have very different backgrounds their master theses have been quite different: From writing open software tools to detect bolides in video observations of Jupiter atmosphere to the photometric calibration and scientific use or their own Jupiter and Saturn images or the study of atmospheric motions of the Venus' South Polar Vortex using data from the Venus Express spacecraft. As a result of this interaction with the students some of them have been engaged to initiate Ph.D.s in planetary sciences enlarging a relative small field in Spain.

URJC GB dataset: Community-based seed bank of Mediterranean high-mountain and semi-arid plant species at Universidad Rey Juan Carlos (Spain).  


The Germplasm Bank of Universidad Rey Juan Carlos was created in 2008 and currently holds 235 accessions and 96 species. This bank focuses on the conservation of wild-plant communities and aims to conserve ex situ a representative sample of the plant biodiversity present in a habitat, emphasizing priority ecosystems identified by the Habitats Directive. It is also used to store plant material for research and teaching purposes. The collection consists of three subcollections, two representative of typical habitats in the center of the Iberian Peninsula: high-mountain pastures (psicroxerophylous pastures) and semi-arid habitats (gypsophylic steppes), and a third representative of the genus Lupinus. The high-mountain subcollection currently holds 153 accessions (63 species), the semi-arid subcollection has 76 accessions (29 species,) and the Lupinus subcollection has 6 accessions (4 species). All accessions are stored in a freezer at -18 °C in Kilner jars with silica gel. The Germplasm Bank of Universidad Rey Juan Carlos follows a quality control protocol which describes the workflow performed with seeds from seed collection to storage. All collectors are members of research groups with great experience in species identification. Herbarium specimens associated with seed accessions are preserved and 63% of the records have been georreferenced with GPS and radio points. The dataset provides unique information concerning the location of populations of plant species that form part of the psicroxerophylous pastures and gypsophylic steppes of Central Spain as well as populations of genus Lupinus in the Iberian Peninsula. It also provides relevant information concerning mean seed weight and seed germination values under specific incubation conditions. This dataset has already been used by researchers of the Area of Biodiversity and Conservation of URJC as a source of information for the design and implementation of experimental designs in these plant communities. Since they are all active subcollections in continuous growth, data is updated regularly every six months and the latest version can be accessed through the GBIF data portal at This paper describes the URJC Germplasm Bank and its associated dataset with the aim of disseminating the dataset and explaining how it was derived.

This article is a testimonial written by the first author regarding the research work performed with Drosophila between 1943 and 1959, at the Departamento de Biologia Geral of the Universidade de São Paulo (USP), which permitted the building of a nucleus of excellence. This research work, focused on the systematics and population genetics of the Neotropical species, began during the first of Dobzhansky's six visits to USP. Special attention was given to the multinational megaprojects conducted during his longer stays, from August 1948 to July 1949 and from June 1955 to July 1956. The role played by the Rockefeller Foundation is duly remembered, and so is the undeniable contribution brought by Dobzhansky, to the establishment of several laboratories dedicated to research in the field of natural population genetics and to the qualification of human resources. On the other hand, important "backstage" episodes are retrieved which were omitted in the official history and occurred from the planning to the execution of the project, carried out on the Angra dos Reis islands. Special attention was given to the relationship problems which resulted from Dobzhansky's, the leader's, difficult personality and contributed to the failure of the second and last multinational project.

Birds of Antioquia: Georeferenced database of specimens from the Colecci?n de Ciencias Naturales del Museo Universitario de la Universidad de Antioquia (MUA)  

PubMed Central

Abstract The department of Antioquia, Colombia, lies in the northwestern corner of South America and provides a biogeographical link among divergent faunas, including Caribbean, Andean, Pacific and Amazonian. Information about the distribution of biodiversity in this area is of relevance for academic, practical and social purposes. This data paper describes the dataset containing all bird specimens deposited in the Colección de Ciencias Naturales del Museo Universitario de la Universidad de Antioquia (MUA). We curated all the information associated with the bird specimens, including the georeferences and taxonomy, and published the database through the Global Biodiversity Information Facility network. During this process we checked the species identification and existing georeferences and completed the information when possible. The collection holds 663 bird specimens collected between 1940 and 2011. Even though most specimens are from Antioquia (70%), the collection includes material from several other departments and one specimen from the United States. The collection holds specimens from three endemic and endangered species (Coeligena orina, Diglossa gloriossisima, and Hypopirrhus pyrohipogaster), and includes localities poorly represented in other collections. The information contained in the collection has been used for biodiversity modeling, conservation planning and management, and we expect to further facilitate these activities by making it publicly available.

The Dasypodidae (Mammalia, Xenarthra) from the Urso Fóssil Cave (Quaternary), Parque Nacional de Ubajara, State of Ceará, Brazil: paleoecological and taxonomic aspects.  


This paper deals with xenarthrans osteoderms assigned to Dasypus aff. D. novemcinctus, Euphractus sexcinctus and Cabassous sp. The material was collected in subsurface, from 0.10 to 0.60 m in the Urso Fóssil Cave, Parque Nacional de Ubajara, State of Ceará, northeastern Brazil. The ages of sediment samples from levels 4 and 5 (depths of 0.40 and 0.50 m) were determined by thermoluminescence technique, and indicated ages of 8,000 and 8,200 years BP for each layer respectively. The presence in these layers of early Holocene xenarthrans taxa can contribute to the understanding of the biotic evolution of the northwest region of Ceará during the last 10,000 years. Two of the three identified taxa still occur in the region: Dasypus novemcinctus and Euphractus sexcinctus. The Dasypodidae fauna here reported includes animals with generalist feeding habits and current wide geographical distribution. It is suggested, therefore, that the climatic and environmental conditions in the early Holocene were very similar the actual ones, and that the absence of Cabassous may be conditioned to other factors, such as anthropogenic action and loss of habitat by fragmentation of the vegetation.

La Oficina del Estudio Geologico de los Estados Unidos (U.S. Geological Survey, 0 USGS) ha monitoreado la calidad del agua de la cuenca del Rio Grande (Rio Bravo del Norte) desde 1995 como parte de la rediseiiada Red Nacional para Contabilizar la Calidad del Agua de los Rios (National Stream Quality Accounting Network, o NASOAN) (Hooper and others, 1997). EI programa NASOAN fue diseiiado para caracterizar las concentraciones y el transporte de sedimento y constituyentes quimicos seleccionados, encontrados en los grandes rios de los Estados Unidos - incluyendo el Misisipi, el Colorado y el Columbia, ademas del Rio Grande. En estas cuatro cuencas, el USGS opera actualmente (1998) una red de 40 puntos de muestreo pertenecientes a NASOAN, con un enfasis en cuantificar el flujo en masa (la cantidad de material que pasa por la estacion, expresado en toneladas por dial para cada constituyente. Aplicacando un enfoque consistente, basado en la cuantificacion de flujos en la cuenca del Rio Grande, el programa NASOAN esta generando la informacion necesaria para identificar fuentes regionales de diversos contaminantes, incluyendo sustancias qui micas agricolas y trazas elementos en la cuenca. EI efecto de las grandes reservas en el Rio Grande se puede observar segun los flujos de constituyentes discurren a 10 largo del rio. EI analisis de los flujos de constituyentes a escala de la cuenca proveera los medios para evaluar la influencia de la actividad humana sobre las condiciones de calidad del agua del Rio Grande.

The Tutorial Education Program on the Formation of the New Milenium's Meteorologist: 20 Years of Project Experience at Universidade Federal de Pelotas - Brazil  

NASA Astrophysics Data System (ADS)

The Programa de Educação Tutorial (Tutorial Education Program), also known as "PET", has the objective to finance students with potential, encouraging and providing extracurricular activities in order to promote the integration with the academic market and the development of study programs in graduate school, preparing a professional that in the future will operate in a global market, transforming and fighting for the professional interests of their class. The design of the program dates back to 1970 and is based on the model of learning and guidance to form the student. The groups are composed gradually, through an annual selection. The deployment and implementation of the groups consider the inclusion of new members in different stages of their school program, working in an integrated manner. To apply, students must submit satisfactory academic performance, without failures on any course and commit to devote a minimum of twenty hours per week to the program activities. Deployed at Universidade Federal de Pelotas - Brazil, in 1991, the group has contributed to the training of students of Meteorology through the concept of teaching-research-extension activities. We believe that PET has been of utmost importance in the training of the new millennium's professional, given that the objectives of this program seek to provide an excellent level of academic training to undergraduates, encouraging their entry into the graduate studies; stimulating the improvement of the quality of teaching degree through the development of new practices and teaching experience; multiplying the activities developed by scholars and increase their interactions with program's faculty and other students of the institution. With the highly competitive market requiring specialized professionals, the high investment in students with potential can be reversed for the benefit of the profession.

Teaching Planetary Sciences with the Master in Space Science and Technology at Universidad del País Vasco UPV/EHU: Theory and Practice works  

NASA Astrophysics Data System (ADS)

The Master in Space Science and Technology is a postgraduate course at the Universidad del País Vasco in Spain ( It has two elective itineraries on space studies: scientific and technological. The scientific branch is intended for students aiming to access the PhD doctorate program in different areas of space science, among them the research of the solar system bodies. The theoretical foundations for the solar system studies are basically treated in four related matters: Astronomy and Astrophysics, Physics of the Solar System, Planetary Atmospheres, and Image Processing and Data Analysis. The practical part is developed on the one hand by analyzing planetary images obtained by different spacecrafts from public archives (e. g. PDS), and on the other hand from observations obtained by the students employing the 50 cm aperture telescope and other smaller telescopes from the Aula EspaZio Gela Observatory at the Engineering Faculty. We present the scheme of the practice works realized at the telescope to get images of the planets in different wavelengths pursuing to study the following aspects of Planetary Atmospheres: (1) Data acquisition; (2) Measurements of cloud motions to derive winds; (3) Measurement of the upper cloud reflectivity at the different wavelengths and position in the disk to retrieve the upper cloud properties and vertical structure. The theoretical foundations accompanying these practices are then introduced: atmospheric dynamics and thermodynamics, and the radiative transfer problem. Acknowledgments: This work was supported by Departamento de Promoción Económica of Diputación Foral Bizkaia through a grant to Aula EspaZio Gela at E.T.S. Ingeniería (Bilbao, Spain).

The development of the Heliometer of the Observatorio Nacional of Rio de Janeiro and application to the study of the Sun-Earth system  

NASA Astrophysics Data System (ADS)

This work presents the development and construction of the Heliometer of the Observatório Nacional/MCTI. This instrument is designed to monitor changes on the solar diameter with the accuracy of the next-generation solar satellites. A review of the heliometric method is made and the building and testing of 4 prototypes is described. The instrument has a mirror objective split in dihedral, formed by the hemi-sections of a parabolic mirror. The materials that form the instrument have thermal and mechanical stability to 10^(-7). The number of optical parts is minimized and their quality is greater than {?}/12. An original software for the automated collection and analysis of the images was developed. With its latest version fully developed, we conducted an observational campaign of 9 days, deriving more than 70000 heliometric images of the Sun. The measured solar diameter has a standard deviation of 0.5 arcseconds, with no instrumental bias, and limited only by the provisional atmospheric modeling. Therefore, by improving the statistics, an accuracy at milliarcseconds can be achieved. A study of the correlation between the solar diameter and the geomagnetic field intensity was made. A correspondence between the peaks of the series related to solar activity, namely, the semidiameter variation, the flares index, and the sunspots counts, and the number of negative peaks on the intensity of the geomagnetic field is found. It must be cautioned though that it is a complex correspondence, requiring different modes of response and phase dependence on the stage of the cycle of solar activity. The straightforward interpretation of observational evidence indicates that the semidiameter of the Sun seems to vary significantly prior to the corresponding variations of the geomagnetic field. The effect is most evident in the downward phase of the solar cycle.

First steps of vulagarization of science in the late ninetheen century: The Yearbook of the Observatorio Astronomico Nacional de Chapultepec, Mexico during the period of Mr. Angel Anguiano (1878-1889)  

NASA Astrophysics Data System (ADS)

Since the founding of the Observatorio Astronomico Nacional de Chapultepec in 1878 during the presidential term of General Porfirio Diaz, begins the publication of the Yearbook of the Observatorio Astronomico Nacional de Chapultepec (from now on OAN) in a period when the positivist paradigm based on will boost science as a means of national progress. Here we describe the actions taken by the observatory's director and editor of the publication, the engineer Angel Anguiano, to initiate and successfully carry out the exchange of scientific publications and / or dissemination through the exchange of the Yearbook of the OAN, both nationally and internationally. The importance of conferences to which he attended started the sharing printed information relating to subjects such as astronomy, meteorology, cartography and geography. The Yearbook was intended to publish two or three months before the beginning of each year and according to the editor would serve to popularize science, making its contents available to anyone with basic knowledge of geometry or for amateur astronomers. I find that the yearbook was the publication that was released to the observatory in the country and abroad, but was sent to distant places where no one speaks or reads Spanish. I think that the content of articles published in, did not respond and objective and informative to the public as mentioned by, because at the late 1800s, 90% of the inhabitants of the Mexican Republic were illiterate and lived in rural areas. The access to the Bulletin was the Mexican intellectual elite grouped into societies, astronomical or meteorological observatories and another wealthy person individually. The same happened abroad. The collection of data from reports to the Secretaria de Fomento, that was the government agency that funds money destined to different scientific institutions founded during this period were published in the Yearbook, the oficios that sent the OAN over a hundred sites in the world responding to the exchange of scientific publications of the mentioned areas through the Library. These documents are available on the Fund of National Astronomical Observatory Historical Archive of the UNAM. The importance of this publication is reflected in the fact that it has continued publishing without interruption since 1881 and gave rise to the Bulletin of the OAN which later became the Boletin del Observatorio Astronomico Nacional de Tacubaya in and finally to the Boletin del Observatorio Astronomico Nacional de Tonantzintla y Tacubaya.

Percepcion de los profesores universitarios acerca del concepto cultura cientifica y de sus implicaciones en el nuevo bachillerato del Recinto de Rio Piedras de la Universidad de Puerto Rico  

NASA Astrophysics Data System (ADS)

El Senado Academico del Recinto de Rio Piedras de la Universidad de Puerto Rico aprobo en el ano academico 2005-2006 la Certificacion 46, que contiene los lineamientos de un nuevo bachillerato. Este nuevo bachillerato introdujo cambios significativos en el curriculo tradicional. Entre ellos se encuentra la reduccion del componente de educacion general y el de Ciencias Biologicas en particular. La reduccion de creditos en el componente de Ciencias Biologicas ha obligado a reevaluar el concepto de cultura cientifica que desarrollan esos cursos. El proposito del estudio consistio en auscultar las percepciones de los profesores de las Facultades de Administracion de Empresas, Humanidades, Ciencias Sociales, Ciencias Naturales, Educacion y Estudios Generales del Recinto de Rio Piedras de la Universidad de Puerto Rico en torno al concepto de cultura cientifica, los contenidos disciplinares del curso de Ciencias Biologicas y la reduccion de creditos en el nuevo bachillerato. Las preguntas que guiaron la investigacion fueron: ¿cuales son las percepciones que tienen los profesores de las Facultades de Administracion de Empresas, Ciencias Sociales, Estudios Generales, Ciencias Naturales, Humanidades y Educacion, en torno al concepto de cultura cientifica y los contenidos disciplinares del curso de Ciencias Biologicas? ¿cuales son las percepciones que tienen los profesores de Ciencias Biologicas en torno al concepto cultura cientifica y los contenidos disciplinares del curso de Ciencias Biologicas? ¿existen diferencias significativas por facultad, genero, experiencia, rango y nombramiento en las percepciones que tienen los profesores del Recinto de Rio Piedras de la Universidad de Puerto Rico sobre los elementos que caracterizan la cultura cientifica y los contenidos biologicos que deben tener los egresados del Recinto? ¿que implicaciones curriculares tienen estos testimonios en el desarrollo del concepto de cultura cientifica en el nuevo bachillerato? Para realizar la investigacion se utilizo una metodologia cuantitativa y la herramienta para lograrlo fue una encuesta. La encuesta se analizo estadisticamente mediante analisis de frecuencias y por cientos, prueba ANOVA, prueba t, pruebas Post Hoc de Tukey y de Levene. Tambien se realizo nuevamente una prueba de confiabilidad mediante el alfa de Cronbach. Los resultados reflejaron que los profesores de las Facultades de Administracion de Empresas, Ciencias Sociales, Ciencias Naturales, Educacion, Humanidades, Estudios Generales y el Departamento de Ciencias Biologicas tienen una percepcion muy positiva del concepto de cultura cientifica, los contenidos curriculares de Ciencias Biologicas y del nuevo bachillerato.

PREFACE: 21st Latin American Symposium on Solid State Physics (SLAFES XXI)  

NASA Astrophysics Data System (ADS)

The Latin American Symposium on Solid State Physics (SLAFES) started in Caracas-Venezuela, and over time the symposia have taken place in 9 different Latin American countries. The last five events took place in Mérida-Venezuela (2002), Havana-Cuba (2004), Puebla-Mexico (2006), Puerto Iguazú-Argentina (2008) and Maragogi-Brazil (2011). During the last years, in the different SLAFES editions, the aim has been to bring together researches from Latina America and invite renowned scientists from around the world to a unique forum to discuss the latest developments regarding Solid state Physics. The 21st Latin American Symposium on Solid State Physics (SLAFES XXI) was held in Villa de Leyva-Colombia, from September 30 to October 04, 2013. The 21st SLAFES version featured the participation of experts in various areas of Solid State Physics from countries such as Belgium, Germany, United States, Spain, Ireland, Chile, Argentina and Brazil, had 270 submitted works and was attended by 140 researchers. The development of this event was made possible by financial support from the Universidad Pedagógica y Tecnológica de Colombia, Universidad Nacional de Colombia, Universidad del Norte-CO, Universidad de Magdalena-CO, Universidade Federal de Pernambuco-BR and the Academia Colombiana de Ciencias Exatas, Naturales y Física.

Acoustics: A branch of engineering at the Universidad Austral de Chile (UACh)  

NASA Astrophysics Data System (ADS)

At the end of the 1960s, the first acousticians graduating at UACh had acquired an education in applied physics and musical arts, since there was no College of Engineering at that time. Initially, they had a (rather modest) four-year undergraduate program, and most of the faculty were not specialized teachers. The graduates from such a program received a sound engineering degree and they were skilled for jobs in the musical industry and sound reinforcement companies. In addition, they worked as sound engineers and producers. Later, because of the scientific, industrial and educational changes in Chile during the 1980s, the higher education system had massive changes that affected all of the undergraduate and graduate programs of the 61 universities in Chile. The UACh College of Engineering was officially founded in 1989. Then, acoustics as an area of expertise was included, widened and developed as an interdisciplinary subject. Currently, the undergraduate program in acoustics at UACh offers a degree in engineering sciences and a 6-year professional studies in Civil Engineering (Acoustics), having two main fields: Sound and Image, and Environment and Industry.

Survey of emission-line galaxies: Universidad Complutense de Madrid list  

NASA Technical Reports Server (NTRS)

A low-dispersion objective-prism survey for low-redshift emission-line galaxies (ELGs) is being carried out by the University Complutense de Madrid with the Schmidt telescope at the German-Spanish Observatory of Calar Alto (Almeria, Spain). A 4 deg full aperture prism, which provides a dispersion of 1950 A/mm, and IIIaF emulsion combination has been used to search for ELGs selected by the presence of H-alpha emission in their spectra. Our survey has proved to be able to recover objects already found by similar surveys with different techniques and, what is more important, to discover new objects not previously cataloged. A compilation of descriptions and positions, along with finding charts when necessary, is presented for 160 extragalactic emission-line objects. This is the first list, which contains objects located in a region of the sky covering 270 sq deg in 10 fields near alpha = 0(sup h) and delta = 20 deg.

[Cutaneous myiasis by Cochliomyia hominivorax (Coquerel) (Diptera Calliphoridae) in Hospital Universidad del Norte, Soledad, Atlántico].  


Human myiasis is the parasitism of human tissues by fly larvae. Diagnoses are based on clinical pattern of tissue damage and presence of insect stages. Herein, a case myiasis is described in a seven-year-old female child. She presented with fever associated with abscessed scalp lesions containing exposed larvae. Severe pediculosis was also observed. The patient was hospitalized and treated with clindamycin, gentamicin (for bacterial secondary infections) and ivermectin (treatment for lice) after which the patient showed clinical improvement and was discharged four days later. Since human myiasis can be caused by a number of different species, larvae were collected from the patient and identified as those of Cochliomyia hominivorax (Diptera: Calliphoridae). Because other cases of coinfestation of flies and lice are on record, health workers are to be alerted about the possible pediculosis-myasis risk. PMID:19753834

Short-period cataclysmic variables at Observatorio Astronomico Nacional IA UNAM.  

NASA Astrophysics Data System (ADS)

We present results of time-resolved spectroscopy and photometry of faint (∼17-19 mag) Cataclysmic Variable stars with periods around the minimum orbital period (∼80 min). In this work we concentrated to our results of study of CVs systems which have evolved beyond the period minimum (so-called bounce-back systems). Using various instruments attached to 2.1m, 1.5m and 0.84m telescopes of OAN SPM of IA UNAM we explored conditions and structure of accretion disks in those short-period Cataclysmic Variables. We showed that the accretion disk in a system with an extremely low mass ratio (≤0.05) grows in the size reaching 2:1 resonance radius and is relatively cool. The disk in such systems also becomes largely optically thin in the continuum, contributing to the total flux less than the stellar components of the system. In contrast, the viscosity and the temperature in spiral arms formed at the outer edge of the disk are higher and their contribution in continuum plays an increasingly important role. We model such disks and generate light curves which successfully simulate the observed double-humped light curves in the quiescence. Thanks to support of our programs by the Time Allocation Commission of OAN SPM, the perfect astroclimate in the observatory, and the phase-locked method of spectroscopic observations, the significant progress in the study of bounce-back systems using a small size telescope was reached.

In this paper, we analyze Juan de la Fuente's life and work. De la Fuente was a medical doctor with medical studies in Sigüenza and Sevilla, minor Spanish universities at that time. Born in Mallorca, he came to New Spain in 1563 and later, he was the first professor in the new Faculty of Medicine in the Royal and Pontifical University of Mexico. His life could be considered as an example of a brilliant professional career developed by a Spanish Medical Doctor coming to the New World, in his case to Mexico. Being a doctor in the main Mexican hospitals, and caring for numerous and select patients. Also was selected as visitador and protomédico, important responsibilities in the regulation of medical practice and quality of medicaments. As a cultivated man, he was a typical case of a humanist. He not only was interested in medicine, but also in natural history, dialectics and philosophy, with a good knowledge of Latin, classical literature and so on. He won the first Medicine Cathedral in 1578 and continued in this place until his death. PMID:21982197

Mediterranean alcohol-drinking pattern and mortality in the SUN (Seguimiento Universidad de Navarra) Project: a prospective cohort study.  


Moderate alcohol intake has been related to lower mortality. However, alcohol use includes other dimensions beyond the amount of alcohol consumed. These aspects have not been sufficiently studied as a comprehensive entity. We aimed to test the relationship between an overall alcohol-drinking pattern and all-cause mortality. In a Mediterranean cohort study, we followed 18 394 Spanish participants up to 12 years. A validated 136-item FFQ was used to assess baseline alcohol intake. We developed a score assessing simultaneously seven aspects of alcohol consumption to capture the conformity to a traditional Mediterranean alcohol-drinking pattern (MADP). It positively scored moderate alcohol intake, alcohol intake spread out over the week, low spirit consumption, wine preference, red wine consumption, wine consumed during meals and avoidance of binge drinking. During the follow-up, 206 deaths were identified. For each 2-point increment in a 0-9 score of adherence to the MADP, we observed a 25 % relative risk reduction in mortality (95 % CI 11, 38 %). Within each category of alcohol intake, a higher adherence to the MADP was associated with lower mortality. Abstainers (excluded from the calculations of the MADP) exhibited higher mortality (hazard ratio 1·82, 95 % CI 1·14, 2·90) than participants highly adherent to the MADP. In conclusion, better adherence to an overall healthy alcohol-drinking pattern was associated with reduced mortality when compared with abstention or departure from this pattern. This reduction goes beyond the inverse association usually observed for moderate alcohol drinking. Even moderate drinkers can benefit from the advice to follow a traditional MADP. PMID:24480368

Bioenergetics and diving activity of internesting leatherback turtles Dermochelys coriacea at Parque Nacional Marino Las Baulas, Costa Rica.  


Physiology, environment and life history demands interact to influence marine turtle bioenergetics and activity. However, metabolism and diving behavior of free-swimming marine turtles have not been measured simultaneously. Using doubly labeled water, we obtained the first field metabolic rates (FMRs; 0.20-0.74 W kg(-1)) and water fluxes (16-30% TBW day(-1), where TBW=total body water) for free-ranging marine turtles and combined these data with dive information from electronic archival tags to investigate the bioenergetics and diving activity of reproductive adult female leatherback turtles Dermochelys coriacea. Mean dive durations (7.8+/-2.4 min (+/-1 s.d.), bottom times (2.7+/-0.8 min), and percentage of time spent in water temperatures (Tw) < or =24 degrees C (9.5+/-5.7%) increased with increasing mean maximum dive depths (22.6+/-7.1 m; all P< or =0.001). The FMRs increased with longer mean dive durations, bottom times and surface intervals and increased time spent in Tw< or =24 degrees C (all r2> or =0.99). This suggests that low FMRs and activity levels, combined with shuttling between different water temperatures, could allow leatherbacks to avoid overheating while in warm tropical waters. Additionally, internesting leatherback dive durations were consistently shorter than aerobic dive limits calculated from our FMRs (11.7-44.3 min). Our results indicate that internesting female leatherbacks maintained low FMRs and activity levels, thereby spending relatively little energy while active at sea. Future studies should incorporate data on metabolic rate, dive patterns, water temperatures, and body temperatures to develop further the relationship between physiological and life history demands and marine turtle bioenergetics and activity.

[Consensus report for the clinical care of smoking cessation in Spain. Comité Nacional para la Prevención del Tabaquismo].  


Tobacco use presents an odd confluence of circumstances: it is a significant and high threat to health, and there is a lack of motivation among health workers to act accordingly. Yet we have effective interventions. It is really hard to identify any other determinant of health presenting this mixture of lethality, prevalence, and lack of care, despite having effective treatments readily available. On the other hand, smoking cessation interventions are considered as the gold standard of preventive interventions, far above other preventive measures commonly used. This has prompted the National Committee for Smoking Prevention to develop a consensus document for the Clinical Care of Smoking Cessation in Spain. The purpose of this technical and scientific document is to agree on a basic proposal of quality of care to tackle smokers to quit. This document would serve as a guideline in the clinical practice in our country. The aims of this agreement are to review the effectiveness of the existing therapies for smoking cessation, to synthesize their available evidence, and to set the basic minimum standards of care in the clinical practice of patients who smoke. The consensus sets the strategies, and the evidences that support them, in order to assist both the smokers who want to quit, and the smokers who do not, setting out the steps to intervene in the most adequate.

PREFACE: XIV Mexican School on Particles and Fields  

NASA Astrophysics Data System (ADS)

The XIV Mexican School on Particles and Fields took place from 8-12 November, 2010, in the colonial city of Morelia, Michoacan, Mexico. The format of the school was such that the morning sessions were devoted to theoretical and experimental reviews, whereas parallel thematic sessions were held in the afternoons. All the reviews and seminars were delivered by experts of international prestige on subjects which are of current interest to the global scientific community and are also actively pursued within Mexico. In order to equip the attending graduate students and post docs with the necessary introductory tools to allow them to benefit substantially from the specialized seminars, a series of mini-courses were offered prior to the event from 4-7 November 2010, in the Auditorium of the Faculty of Science of the University of Michoacan (UMSNH). The length of each course was about 5 hours, English being the language of instruction. An informal and friendly atmosphere was encouraged during the courses so that the students could overcome their inhibitions and actively participate in the discussions. A novel feature of this event was a colloquium aimed at the general public and younger students of pre-undergraduate level, which allowed the expert scientists to reach out to a wider community and raise their awareness and interest in one of the most fascinating and vital fields of knowledge. The XIV-MSPF was organized by the Division of Particles and Fields of the Mexican Physical Society. It was generously sponsored by several institutions: Consejo Estatal de Ciencia y Tecnológico (COECyT) del Estado de Michoacán, Universidad Michoacana de San Nicolás de Hidalgo, Universidad de Sonora, Universidad Nacional Autónoma de México, Universidad de Guanajuato, Universidad de Sinaloa, Centro de Investigaciones de Estudios Avanzados del IPN (CINVESTAV), Consejo Nacional de Ciencia y Tecnología (CONACyT), la Academia Mexicana de Ciencias and, most importantly, the Red Nacional de Física de Altas Energías. At a personal level, we are very grateful to Dr Juan Carlos D'Olivo (President of the Red Nacional de Física de Altas Energías), Dr Pedro Mata Vázquez (Director of COECyT), Dr Ricardo Becerril Bárcenas (Director of the Institute of Physics and Mathematics, UMSNH), Dr Rigoberto Vera Mendoza (Director of the Faculty of Science, UMSNH) and Dr José Napoleón Guzmán Ávila (Coordinator of Scientific Research, UMSNH) for their invaluable support in all organizational matters, which enabled the school to become a reality. We gratefully acknowledge the help of our colleagues in the organizing committee: Alexis Aguilar, Alejandro Ayala, Wolfgang Bietenholz, Alberto Güijosa, Gabriela Murguía, Sarira Sahu (UNAM), Eduard de la Cruz Burelo, Abdel Pérez-Lorenzana (CINVESTAV), Elena Cáceres (UCOL), David Delepine (UG), Mariana Kirchbach (UASLP), Ildefonso León (UAS), Juan Carlos Arteaga-Velázquez (for his impeccable work in managing the web page of the school) and Víctor Villanueva (UMSNH). Most of them contributed to the extra work involved in refereeing the contributions submitted for this publication. Many thanks also go to all the student volunteers for the efficiency and dedication with which they carried out their duties. At the registration desk, we relied on the hard work of Xiomara Gutiérrez, Enif Gutiérrez (UMSNH) and Mara Diaz Pancardo. Several post docs and PhD students provided invaluable support in all organizational matters: Adolfo Huet, Cliffor Compeán, Rocío Bermúdez, Saúl Sánchez, Anabel Trejo, Iraís Rubalcava, Khépani Raya, José Juan González, Saúl Hernández Ortiz (UMSNH), Alfredo Galaviz, and Alan Aganza (USON). Their help in carrying out the organization of the school was essential and without their collaboration, this school would not have been the same. We also acknowledge the help of the administrative secretary Maria Esperanza Jaramillo of IFM (UMSNH). We would like to take this opportunity to thank all the speakers for delivering excellent lectures and seminars which made this event a success.

[Speech by Carlos Matus in the presentation of Adiós, Señor Presidente].  


The text of this article was written by Carlos Matus and read aloud by him at the first presentation of his book Adiós, Señor Presidente [Goodbye, Mr. President] in Venezuela in 1987. Matus describes the problems of the governments of Latin America of that day, in order to address the growing gap between the capacity of governments to govern and the complexity of social systems. For Matus, bridging this gap requires theories, techniques, systems and methods so as to develop government projects in which the governability of the system is not less than the magnitude of its problems. This document was recovered from the Mario Testa fund, in the Center for Documentation and Research Pensar en Salud (CEDOPS) of the Institute of Collective Health in the Universidad Nacional de Lanús.

[Reflexions about the curricula at the faculty of medicine in the XXI century].  


In this paper we review the main medical programs from the Universidad Nacional Autonoma de Mexico (UNAM) faculty of medicine in the first seventy-five years of twentieth century. We have selected those instances that are representative of special moments in the development of Mexican medical knowledge, and also corresponding to the need to prepare medical students in view of social demands. The first programs are those of Ignacio Chavez in 1934, concerned mainly with the introduction into the curricula of medical specialties such as cardiology or neurology. After those, the 1956 and 1960 programs are mentioned and briefly analyzed; both were founded on the concern to develop a clinical reasoning in the student. Finally, the 1974 Integral General Medicine Program directed its interest to social and environmental themes. PMID:21527967

Statistical panorama of female physics graduate students for 2000-2010 in Peru  

NASA Astrophysics Data System (ADS)

We report the results of a statistical study on the number of women entering the undergraduate and master's programs of physics at Universidad Nacional Mayor de San Marcos in Peru. From 2006 through 2010, 13 female students entered the master's degree program but no females graduated with the degree. Considering that Peru is a developing country, a career in physics is not considered an attractive professional choice even for male students because it is thought that there are no work centers to practice this profession. We recommend that the causes preventing female physics students from completing their studies and research work be analyzed, and that strategies be planned to help women complete their academic work. We are considering getting help from the Peruvian Physics Society (SOPERFI) in order to draw more attention for our plan.

Education and public outreach during the spring equinox, 2012  

NASA Astrophysics Data System (ADS)

We organized for third occasion a solar physics activities during the spring equinox of 2012. On March 20 a group of researchers and their graduate students, amateur astronomers and educators all of them members of the Universidad Nacional Autónoma de México (UNAM) went to a beautiful village named Tepoztlan, Morelos, located 30 minutes from the City and Mexico. We give lectures and install solar telescopes in the garden of the former convent of Tepoztlan near a mountain considered sacred. During the equinox day the mountain is climbed by thousands of individuals to catch solar energy that they consider vital, specially during a year that many of them consider the end of a era. Through media and advertisements we invite visitors to our free event. We expected to hear different assumptions about our closest star, the Sun, and interact with different socio-cultural views at the same time that we presented our concepts of science in a every day language.

HAMC2 Astrometry and Photometry calibration and comparison of its data with those of other modern CCD catalogues  

NASA Astrophysics Data System (ADS)

The second Hispano-Argentinian Meridian Catalogue (HAMC2) contains more than 12.500.000 positions and magnitudes of stars brighter than V=16.5 and with declinations between -30° and 0°. It has been computed from the CCD observations of the San Fernando Automatic Meridian Circle (CMASF) installed at present at the Carlos U. Cesco Observatory (CUC) in San Juan (Argentina). The CMASF is operated jointly by the Real Instituto y Observatorio de la Armada (ROA) of Spain, owner of the instrument, and the Observatorio Astronómico Félix Aguilar (OAFA) of the Universidad Nacional de San Juan (Argentina), owner of the CUC. The catalogue will be published in the first half of 2008. In this paper we present the work carried out to implement the HAMC2, the CCD camera sensor calibration and finally the comparison of its astrometric and photometric results with other modern CCD catalogues in order to detect and to remove possible systematic errors.

Evaluation of a solar intermittent refrigeration system for ice production operating with ammonia/lithium nitrate  

SciTech Connect

A novel solar intermittent refrigeration system for ice production developed in the Centro de Investigacion en Energia of the Universidad Nacional Autonoma de Mexico is presented. The system operates with the ammonia/lithium nitrate mixture. The system developed has a nominal capacity of 8 kg of ice/day. It consists of a cylindrical parabolic collector acting as generator-absorber. Evaporator temperatures as low as -11 C were obtained for several hours with solar coefficients of performance up to 0.08. It was found that the coefficient of performance increases with the increment of solar radiation and the solution concentration. A dependency of the coefficient of performance was not founded against the cooling water temperature. Also it was found that the maximum operating pressure increases meanwhile the generation temperature decreases with an increase of the solution concentration. (author)

Gene frequencies and admixture estimates in a Mexico City population.  


Five hundred and ten students of the Universidad Nacional Autónoma de México were tested to determine the distribution of ABO, MN, Rr-Hr blood groups, and serum haptoglobin, albumin, and Factor Bf types. Based on the results we found that the proportion of Indian and White genes are of 56.16 and 43.84%, respectively in the dihybrid model and 2.93, 56.22, and 40.85% for Blacks, Indians, and Whites in the trihybrid one. The present study reveals a higher proportion of Indian genes in the Mexico City population than estimated in previous publications. Reasons why the present results apply to a much larger group of Mexico City mestizos than the previous ones are given. PMID:3099584

RATIR: Reionization and Transients Infra-Red Camera. A New Instrument to Identify High Red-Shift GRBs  

NASA Technical Reports Server (NTRS)

We are currently constructing the cryogenic infrared portion of the RATIR instrument at NASA's Goddard Space Flight Center (GSFC) in collaboration with University of California, Berkeley (UCB) and The University of Mexico (UNAM). The infrared instrument will consist of two 2048x2048 Hawaii 2RG detectors, one on axis and one off axis using diachronic. The detectors will be operated using state-of-the-art Teledyne SIDECAR (System Image, Digitizing, Enhancing, Controlling, And Retrieving) ASICs (Application- Specific Integrated Circuits) similar to NIRSpec on JWST. The visible portion of the instrument is currently being developed at UCB consisting of two CCD imagining cameras. Once completed, the two sections will be integrated into the RATIR instrument. Mounted on a dedicated, fully-automated 1.5-m telescope, the instrument will provide rapid (<10 min) identification of VHR GRBs allowing high-resolution spectroscopic follow-up observations with large aperture telescopes possible. The hosting Observatorio Astronomico Nacional of the Universidad Nacional Autonoma de Mexico (UNAM), located on the Sierra de San Pedro Martir in Baja California, Mexico, provides great seeing (-1 aresec), good weather, dark skies, and significant sky coverage so that RATIR will detect a significant number of Swift afterglows. While not all GRBs will be at high red shifts, the resulting light curves, combined with X-ray/UV observations, will address several open questions, including the nature of both "dark GRBs" and the GRB emission mechanism.

NASA Astrophysics Data System (ADS)

The XVII International Conference on Strings, Particles and Cosmology, PASCOS 2012, was held in the City of Mérida, Mexico, from June 3–8, 2012. The conference series is aimed at exploring the interface and interplay between particle physics, string theory and cosmology. With the advent of new data, the emphasis of the XVIII edition of PASCOS was on phenomenology and the interpretation of recent observational and experimental results. The conference followed the format of previous conferences in this series, with plenary reviews and contributed presentations in parallel sessions. The lectures covered a wide range of subjects which included: Dark matter and dark energy, flavor physics and CP violation, neutrino physics, supersymmetry, Higgs physics, baryogenesis and EDMs, supergravity, high energy cosmic rays, string and F–theory GUTs, and string phenomenology. This is the first time that PASCOS was held in Latin America. The aim to do it in Mexico was to engage the Latin American community and thus to bring the conference to a wider and different audience, a goal which was thoroughly achieved. The venue was held at the Hotel Fiesta Americana in the beautiful city of Mérida. The social events included a reception with typical local food at the Katun restaurant, conference dinner at the historical Quinta Montes Molina, and an excursion to the archeological site of Dzibilchaltún including a swim at the famous cenote. PASCOS 2012 was possible thanks to the generous support of the following sponsors: CONACyT (Consejo Nacional de Ciencia y Tecnología), UNAM (Universidad Nacional Autónoma de México: Consejo Técnico de la Investigación Científica, Instituto de Ciencias Nucleares, Instituto de Física), Cinvestav, (Centro de Estudios Avanzados del IPN: U.

NASA Astrophysics Data System (ADS)

The IX Mexican Workshop on Particles and Fields was held in the beautiful city of Colima, in the South-West of Mexico, from 17-22 November 2003. The proceedings of the Workshop were delayed due to problems with a previous publisher, we are very grateful that Journal of Physics: Conference Series kindly agreed to publish the proceedings rapidly at this late stage. The Workshop aimed to cover, through invited lectures delivered by internationally known experts, the most recent developments in the field. There was also a series of short seminars as well as a poster session, which allowed the whole community to participate with their most recent research results. A special session was dedicated to awarding the Division Medal to Professor Benjamin Grinstein, from The University of California, San Diego, for his outstanding contributions to the field. This volume contains the written version of the material presented at the Workshop. The Workshop was attended by more than 100 participants, including faculty members, postdocs and graduate students. It was organized by the Particles and Fields Division of the Mexican Physical Society, and generously sponsored by several institutions: Universidad de Colima, Universidad Nacional Autónoma de México, Universidad Michoacana de San Nicolás Hidalgo, Centro de Investigaciones y Estudios Avanzados del IPN (CINVESTAV), Consejo Nacional de Ciencia y Tecnología (Conacyt).

Umbilical cord blood transplantation in hematologic diseases in patients over 15 years old: long-term experience at the Pontificia Universidad Católica de Chile.  


Most patients who require a sibling stem cell transplantation do not have a matched donor. In our experience, only 1/3 patients have a matched unrelated donor (MUD); therefore, the majority of the patients will require umbilical cord blood (UCB). Patients treated for hematologic diseases with UCB transplants were included. UCB selection and conditioning regimens were performed according to the Minnesota group. Graft-versus-host disease (GVHD) prophylaxis, infection prevention, and patient care were performed according to institutional guidelines. We analyzed patients and graft demography, neutrophil and platelet recovery, chimerism kinetics, GVHD incidence, overall (OS), progression-free survival (PFS) and transplant-related mortality (TRM). We included 29 patients with a median age of 34.8 years (range 15-55). Eighteen were male and the median weight was 72.6 kg (range 54-100). Nineteen patients had acute leukemia. Myeloablative (MA) conditioning was used in 27 patients. Seventeen received double UCB (DUCB) grafts. Median total nucleated cell (10(7)/kg) was 4.2 (range 3.9-4.9) and 4.4 (range 2.8-6.3) for single UCB (SUCB) and DUCB transplants, respectively. Median time for neutrophil engraftment was 24.7 (range 14-43) and 25.8 days (range 14-52) after SUCB and DUCB transplants, respectively. Median time for platelet engraftment was 147 (range 30-516) and 81 days (range 37-200) after SUCB and DUCB transplants, respectively. All the patients receiving MA conditioning had >95% chimerism shortly after transplant. Cumulative incidence of grades II-IV and III-IV acute GVHD was 41% and 20%, respectively. Localized chronic GVHD was seen in 14% of the patients. Median follow-up was 16.7 months (range 1-63). Five-year OS and PFS were 38% and 39%, respectively. One-year TRM was 42%. UCB transplantation is associated with potential cure of hematologic malignancies and our results are similar to other series. Studies are needed to decrease mortality and improve immune reconstitution. PMID:24315012

We describe a computational procedure to encrypt a message, provided that the transmitter and the receiver dispose of identical, but otherwise not synchronized, chaotic dynamical systems. The technique is based upon the fact that the symbolic dynamics of these two systems can be used in order to sequentially construct data blocks which reproduce those from the input file.

A workshop titled: Environmental Remote Sensing for Natural Resources Management was held from June 12 23, 2006 at Eduardo Mondlane University in Maputo Mozambique. The workshop was initiated through an invitation and pre-course evaluation form to interested NGOs, universities, and government organizations. The purpose of the workshop was to provide training to interested professionals, graduate students, faculty and researchers at Mozambican institutions on the research and practical uses of remote sensing for natural resource management. The course had 24 participants who were predominantly professionals in remote sensing and GIS from various NGOs, governmental and academic institutions in Mozambique. The course taught remote sensing from an ecological perspective, specifically the course focused on the application of new remote sensing technology [the Shuttle Radar Topography Mission (SRTM) C-band radar data] to carbon accounting research in Miombo woodlands and Mangrove forests. The 2-week course was free to participants and consisted of lectures, laboratories, and a field trip to the mangrove forests of Inhaca Island, Maputo. The field trip consisted of training in the use of forest inventory techniques in support of remote sensing studies. Specifically, the field workshop centered on use of Global Positioning Systems (GPS) and collection of forest inventory data on tree height, structure [leaf area index (LAI)], and productivity. Productivity studies were enhanced with the teaching of introductory dendrochronology including sample collection of tree rings from four different mangrove species. Students were provided with all course materials including a DVD that contained satellite data (e.g., Landsat and SRTM imagery), ancillary data, lectures, exercises, and remote sensing publications used in the course including a CD from the Environmental Protection Agency's Environmental Photographic Interpretation Center's (EPA-EPIC) program to teach remote sensing and data CDs from NASA's SAFARI 2000 field campaign. Nineteen participants evaluated the effectiveness of the course in regards to the course lectures, instructors, and the field trip. Future workshops should focus more on the individual projects that students are engaged with in their jobs, replace the laboratories computers with workstations geared towards computer intensive image processing software, and the purchase of field remote sensing instrumentation for practical exercises.

Smoking status, changes in smoking status and health-related quality of life: findings from the SUN ("Seguimiento Universidad de Navarra") cohort.  


We aimed to evaluate the association between smoking, changes in smoking, and quality of life in a cohort of Spanish university graduates. Smoking habits were self-reported at baseline and four years later. Quality of life was assessed using the Short Form-36 (SF-36) at year 4. Statistical differences in SF-36 scores between groups were determined using ANCOVA with age and sex as covariates. Out of 5,234 eligible participants over 2000-2006, there were 2,639 non-smoker participants, 1,419 ex-smokers, and 1,048 smokers. Within the previous four years, 435 participants became recent quitters and 205 starters. Comparing smoking and health status in year 4, non-smokers showed better scores than the other categories of ever smoking in all dimensions except in the vitality scale value, which was similar in non-smokers and in those smoking less than 15 cigarettes/day. Comparing changes in smoking and health in year 4, continuing smokers had statistically significant worse scores than non-smokers in general health, social functioning, role-emotional and mental health, whereas recent quitters showed statistically significant improvements in role-emotional and mental health over those who had continued smoking or those who became smokers. Our findings support a dose-response relationship between cigarette consumption and a worse quality of life in general and mental health in particular. They also support that changes in smoking have an impact on health. PMID:19440285

[Diversity of wild and domestic mammal's intestinal helminths from the Caatinga of the Parque Nacional Serra da Capivara, Southeast of Piauí, Brazil].  


Biodiversity studies allow ecosystem assessment and monitoring of environmental changes and impacts. Parasite diversity could reflect the host/ parasite coevolutionary process and the environment changes that permit the loss, gain or maintenance of species. This survey used species/morphotypes of helminths eggs found in feces from seven wild mammal species (the groups Dasypodidae and Large Cats, and Tamandua tetradactyla, Cebus apella, Alouatta caraya, Cerdocyon thous, Pecari tajacu) and from two domestic species (Canis familiaris and Sus scrofa), which occur within the Serra da Capivara National Park (PNSC) and surrounding areas in order to analise the diversity of mammal intestinal helminths. This work used the helminthological fauna findings of wild and domestic mammals, to consider a possible helminth flux between these two host groups using Unweighted Pair Group Method with Arithmetic Mean (UPGMA) of the hosts based on helminthological fauna composition. The results indicate that the region of the PNSC still maintains environmental conditions that still keep wild mammal helminthological fauna composition different from the one found for domestic mammals.

PREFACE: Introduction to the proceedings of Dynamics Days South America 2010  

NASA Astrophysics Data System (ADS)

This proceedings presents selected contributions from the participants of South America Dynamics Days 2011, which was hosted by the National Institute for Space Research (INPE), Brazil, in July 2010. Dynamics Days was founded in 1980 and is the longest standing and most respected international series of meetings devoted to the field of dynamics and nonlinearity. Traditionally it has brought together researchers from a wide range of backgrounds - including physics, biology, engineering, chemistry and mathematics - for interdisciplinary research into nonlinear science. Dynamics Days South America 2010 marked the beginning of the South American branch of Dynamics Days. It brought together, for the first time in South America, researchers from a wide range of backgrounds who share a common interest in the theory and applications of nonlinear dynamics. Thus, South American researchers had a forum to promote regional as well as international scientific and technological exchange and collaboration especially, but not exclusively, on problems that are particularly relevant for the development of science and technology in the South American region. Furthermore, the conference also brought together prominent scientists from around the world to review recent developments in nonlinear science. This conference comprised plenary invited talks, minisymposia, contributed talks and poster sessions. The articles that are compiled here were chosen from among the works that were presented as contributed talks and posters. They represent a good selection which allows one to put issues that were discussed during the conference into perspective. It is possible to evaluate the success of an initiative by using several indices. In relation to attendees, the conference had 311 participants from 22 countries, who presented 341 works. About 86% of the participants came from South American countries. These figures allow one to classify this Dynamics Days conference as that with the greatest number of attendees ever. Finally, we would like to express our gratitude to all the participants for their presentations, discussions, and remarkable interactions with one another. The tireless work undertaken by all the members of the International Advisory Committee and the Organizing Committee must also be recognized. We also wish to express our deep appreciation for the Scientific Societies and Research Support Agencies which supported the conference and provided all the resources which were necessary to make this idea of a South American Dynamics Days come true.

Astroclimate at San Pedro Mártir - I. Seeing statistics between 2004 and 2008 from the Thirty Meter Telescope site-testing data  

NASA Astrophysics Data System (ADS)

We present comprehensive seeing statistics for the San Pedro Mártir site derived from the Thirty Meter Telescope site-selection data. The observations were obtained between 2004 and 2008 with a Differential Image Motion Monitor (DIMM) and a Multi-Aperture Scintillation Sensor (MASS) combined instrument (MASS-DIMM). The parameters that are statistically analysed here are the whole atmosphere seeing (measured by the DIMM), the free atmosphere seeing (measured by the MASS) and the ground-layer (GL) seeing, which is the difference between the total seeing and the free atmosphere seeing. We have made a careful data coverage study, along with statistical distributions of simultaneous MASS-DIMM seeing measurements, in order to investigate the nightly, monthly, seasonal, annual and global behaviour, as well as possible hourly seeing trends. Although this campaign covers five years, the sampling is uneven, with 2006 and 2007 being the best sampled years in terms of seasonal coverage. The overall results yield a median seeing of 0.78 arcsec (DIMM), 0.37 arcsec (MASS) and 0.59 arcsec (GL). Therefore, the strongest contribution to the whole atmosphere seeing comes from a strong ground layer. We find that the best season is summer, while the worst season is winter, in accordance with previous studies. It is worth noting that the best yearly results are correlated with the best sampled years. The hourly analysis shows that there is no statistically significant tendency for seeing degradation towards dawn. The seeing values are slightly larger than those reported previously, which might be the result of climate changes. Based on observations obtained at the Observatorio Astronómico Nacional at San Pedro Mártir, Baja California, México, operated by the Instituto de Astronomía, Universidad Nacional Autónoma de México.

[Bibliometry of biological systematics in Latin America during the twentieth century in three global databases].  


We present a review of the biological systematic research in Latin America during the twentieth century, applying a bibliometric analysis to the information contained in international databases with the largest number of biological records: Biosis (since 1969), CAB (since 1910) and Science Citation Index (since 1900), to recognize certain patterns and trends regarding the document production. We obtained 19079 documents and 1387 journals for Biosis, 14326 and 2537 for CAB, 3257 and 1636 for SCI. Of the documents, 54.6% related to new species, 15.3% dealt with morphology, 14.9% keys, 12.5% descriptions, 10.6% cases of synonymies, 6% new genera, 4.9% new geographical records, 23.6% geographical distribution, 4.2% redescriptions, and 3.6% with new nomenclatural combinations. The regions mentioned were South America with 11.9%, Central America with 4% and America (all) with 2.56%. Nineteen Latin American countries appear, whereas outside this region we found the United States of America with 12.6% of representation and Canada with 3%. Animals (65.6%) were the most studied taxa, which was 1.7 times higher than what was published for plants (37%), 11 times higher than fungi (6%) and nearly 30 times higher than microorganisms (2.3%). Out of the 155 journals that produced 66% of the papers, 76.5% were better represented in Biosis, 21.4% in CAB and 2% in SCI. Twenty-nine journals published 33% of the articles, the maximum number of records obtained was 69% for Biosis, CAB 24% and 6.9% for SCI, three (10.3%) are in biology, 11 (37.9%) in botany, 13 (44.8%) zoology, and two (6.9%) paleontology; eight of these journals (27.5%) were published in Latin America and twenty were indexed in the Science Citation Index. In the last two years more journals of the region that publish on taxonomy have been indexed, but their impact factor is still low. However, the impact factor of a number of Latin American journals that published biodiversity increased with time. Countries that are more interested in studying the Latin American biota from the taxonomic point of view are Brazil, the United States, Argentina and Mexico. The most active institutions in this discipline were the Universidade de São Paulo, Universidad Nacional Autónoma de México, and the Universidade Federal do Rio de Janeiro; together they produced 24% of the documents.

[Distance learning in the nursing area: report of an experience].  


This study aims at reporting an experience of offering a course in the master program of the Universidad Nacional de Rosário. The purpose is to offer elements for a reflection on a conception of long-distance education, as an adequate and efficient modality of education, aiming at enabling a teaching with quality to a determined clientele. The course was developed in three moments: video-conference, long-distance didactic activities and a seminar. The tutoring was shared by establishing the challenge of having a dialogic relation with the students. Authors believe that long-distance education is an adequate pedagogical tool to qualify nurses who have no access to traditional graduate studies. Therefore it enables the qualification of a greater number of nurses, geographically dispersed, who are unable to scape from the routine of their personal and professional lives. Facing the need to form the country's nursing workers and qualify nurses to act as teachers, long-distance learning is an effective and possible pedagogical strategy. PMID:14978575

Mexican national pyronometer network calibration  

NASA Astrophysics Data System (ADS)

In order to take advantage of the solar radiation as an alternate energy source it is necessary to evaluate the spatial and temporal availability. The Mexican National Meterological Service (SMN) has a network with 136 meteorological stations, each coupled with a pyronometer for measuring the global solar radiation. Some of these stations had not been calibrated in several years. The Mexican Department of Energy (SENER) in order to count on a reliable evaluation of the solar resource funded this project to calibrate the SMN pyrometer network and validate the data. The calibration of the 136 pyronometers by the intercomparison method recommended by the World Meterological Organization (WMO) requires lengthy observations and specific environmental conditions such as clear skies and a stable atmosphere, circumstances that determine the site and season of the calibration. The Solar Radiation Section of the Instituto de Geofísica of the Universidad Nacional Autónoma de México is a Regional Center of the WMO and is certified to carry out the calibration procedures and emit certificates. We are responsible for the recalibration of the pyronometer network of the SMN. A continuous emission solar simulator with exposed areas with 30cm diameters was acquired to reduce the calibration time and not depend on atmospheric conditions. We present the results of the calibration of 10 thermopile pyronometers and one photovoltaic cell by the intercomparison method with more than 10000 observations each and those obtained with the solar simulator.

Array of CCD's for the 1m. Schmidt telescope  

NASA Astrophysics Data System (ADS)

We describe the array of CCDs (YIC Camera) attached to the Schmidt Telescope located in the Observatorio Nacional de Llano del Hato, Merida, Venezuela. Currently the camera has 16 CCDs (2048×2048) cooled to below -80C. The camera can be used in drift-scan mode (within 7deg of equator) or guided mode. Two filter mosaics (UBUV and BVRI) and a low-pass filter with a 7000 AA cutoff are available. An objective prism of dispersion 500 AA/mm is also available. This prototype camera was designed for the QUEST project., a collaboration of Yale and Indiana Universities (USA) with the Universidad de los Andes and CIDA (Venezuela). A second phase camera will have 96 CCDs (4096 by 1024). The system has been working since early 1997. Even thought it is still under commisioning, an important quantity of astronomical data have been acquired. Half of the dark time is assigned to the QUEST project, observing in drift-scan mode with the UBUV filter set, or with the objective prism and no filters. The rest of the time is open to projects like the Survey for low luminosity Hx emission-line galaxies (UCM - CIDA), Variability Survey near the Galactic Plane (Yale, CFA, CIDA, Indiana), Catalogo Astrometrico y movimientos para el area de la "Carte du Ciel" zona San Fernando (CIDA - ROA), Solar System Science (ULA - Yale).

An undergraduate program for astronomy in México  

NASA Astrophysics Data System (ADS)

Astronomy in Mexico has an ancient tradition, reinforced during the XXth century by groups working in theoretical and observational astronomy. During the 90s, the Great Millimeter Telescope (a single 50-m antenna) has been approved, and a 6-m infrared telescope is under study. Graduate and undergraduate programs must be improved to prepare future Mexican and Latin American astronomers to take advantage of these facilities. To meet the challenge, two traditional Mexican programs (Instituto de Astronomia-UNAM and Instituto Nacional de Astrofisica, Optica y Electronica-INAOE) are updating their graduate programs for. Similarly, the Departamento de Astronomia de la Universidad de Guanajuato is joining physicists in the first undergraduate program in Mexico in Physics and Engineering with an option in Astrophysics. This will prepare students so that they can choose between industry, academia or national laboratories, either in Physics or Astronomy. Jobs in academia have been scarce; many students had to give up their goals after one or two postdoctoral positions. Graduate and undergraduate programs must adjust, by broadening the scope of present programs so that students are better prepared for other job opportunities. We present a BSc program designed by astronomers and physicists to try to address some of these concerns and prepare the students for either continuing with graduate studies or finding employment in an ever-changing job market.

Virtual reality and project management for astronomy  

NASA Astrophysics Data System (ADS)

Over the years astronomical instrumentation projects are becoming increasingly complex making necessary to find efficient ways for project communication management. While all projects share the need to communicate project information, the required information and the methods of distribution vary widely between projects and project staff. A particular problem experienced on many projects regardless of their size, is related to the amount of design, planning information and how that is distributed among the project stakeholders. One way to improve project communications management is to use a workflow that offers a predefined way to share information in a project. Virtual Reality (VR) offers the possibility to get a visual feedback of designed components without the expenses of prototype building, giving an experience that mimics real life situations using a computer. In this contribution we explore VR as a communication technology that helps to manage instrumentation projects by means of a workflow implemented on a software package called Discut designed at Universidad Nacional Autónoma de Mexico (UNAM). The workflow can integrate VR environments generated as CAD models.

Radiocarbon dating and compositional analysis of pre-Columbian human bones  

NASA Astrophysics Data System (ADS)

Analysis of ancient human bones found in "El Cóporo", an archaeological site in Guanajuato, Mexico; were performed using a multi techniques scheme: 14C radiocarbon dating, IBA (Ion Beam Analysis), SEM-EDS (Scanning Electron Microscope Energy Dispersive X-ray Spectroscopy). We measured the elemental composition of the bones, especially some with a superficial black pigmentation. Soil samples collected from the burial place were also analyzed. The 14C dating was performed with a new High Voltage Europe 1 MV Tandentron Accelerator Mass Spectrometer (AMS) recently installed in the IFUNAM (Instituto de Física, Universidad Nacional Autónoma de México). The radiocarbon dating allowed us to determine the date of death of the individual in a period between the year 890 and 975 AD, which is consistent with the late period of the Cóporo civilization. The element sample analysis of bones with the surface black pigmentation show higher levels of Fe, Mn and Ba compared when bone's black surface was mechanically removed. These three elements were found in soil samples from the skeleton burial place. These results indicate more likely that the bone black coloration is due to a postmortem alteration occurring in the burial environment.

Technology for communicational development and learning in psychomotor disability  

NASA Astrophysics Data System (ADS)

The applied investigation and experimental development project described in this paper has been carried out by Grupo Ingeniería Clínica of the Universidad Tecnológica Nacional together with two Special Education Schools dependent on the Ministry of Education of Córdoba Province. Its aim is the development of computer access assistive tools for students with mobility limitations, and with or without intellectual problems that need adaptations to access to a computer in order to learn, communicate, work, etc. On the other hand, it demonstrates the benefits that the use of a computer gives to these students. The evaluation of their performance was made trough Dr. Marianne Frostig's Developmental Test of Visual Perception and reading and writing graphic tests, comparing the results of the tests made on paper with those made on computer. Thus, an interdisciplinary team was formed by Engineering, Psychology and Special Education professionals, and 40 students were evaluated. The design of the mouse and keyboard had some adaptations. At present, the rating test stage is being achieved, and the preliminary results allow us to anticipate that pupils with psychomotor disabilities may manifest their perceptual ripeness and reach education in a more efficient way through the use of informatics tools according to their needs and possibilities.

Radioinhibition process in Argentinian garlic and onion bulbs  

NASA Astrophysics Data System (ADS)

Technological aspects of garlic and onion bulbs subjected to the radioinhibition process and extended storage under warehouse conditions were studied. Garlic and onion of the "Colorado" and "Valenciana sintética 14" varieties respectively, were irradiated in dormancy period with an average dose of 50.0 Gy of 60Co gamma rays and kept in storage up to ten months post-harvest. Throughout the control period (180-300 days post-harvest) obvious benefits were attained as to reducing the weight loss and increasing the percentage of marketable bulbs. In general, the irradiated bulbs were superior to the non-irradiated ones with regard to the external aspect, firmness and internal aspect, while the odor of the bulbs was not affected by the process. The radioinhibition process does not seem to affect adversely the levels of dry matter, carbohydrates and ascorbic acid as well as the acidity in onion bulbs. In two marketing trials a very favourable reception was perceived in the consumer public regarding the quality of the products. These studies have promoted the construction of a multipurpose irradiation facility in the Universidad Nacional del Sur for the development of the radiation processing technology.

PREFACE: The XI Mexican School on Particles and Fields  

NASA Astrophysics Data System (ADS)

The XI Mexican School on Particles and Fields took place on 2-13 August 2004, in the city of Xalapa, Veracruz, México. The School continued with the tradition of promoting High Energy Physics among the younger generation in Mexico. Thus, it was aimed specifically at graduate students and postdocs. The School consisted of several courses delivered by international experts on subjects of current interest to the scientific community. The length of each course was of six to eight hours, English being the language of instruction. A novelty in this edition of the School was its total duration (two weeks as opposed to one), the number of hours assigned to one subject, and the addition of some experimental courses for the students to overcome their inhibitions of a direct encounter with the equipment and its usage. There were also a few overview talks delivered by local experts on the current status of some of the research fields actively pursued in Mexico. The XI-MSPF was organized by the Particles and Fields Division of the Mexican Physical Society. It was generously sponsored by several institutions: Universidad de Veracruz, Universidad Nacional Autónoma de México, Universidad Michoacana de San Nicolás de Hidalgo, Centro de Investigaciones y Estudios Avanzados del IPN (CINVESTAV) and Consejo Nacional de Ciencia y Tecnología (CONACyT). We are very grateful to Dr Raúl Arias Lovillo, Dr Víctor Manuel Alcaráz Romero, Dr Asdrúbal Flóres López and Mtro Walter Saiz González, head of the Academic Secretariat, Director and Subdirector of the Office of Scientific Research and Director of the Division of Exact Sciences of the University of Veracruz, respectively, for their invaluable support in all senses to our Summer School. We also appreciate the important and useful assistance provided by Dr Rubén Bernardo Morante López, Director of the Museum of Anthropology of Xalapa, and Dr Héctor Coronel Brizio of the Secretariat of Education and Culture of the state of Veracruz. We acknowledge the help of our colleagues in the Organizing Committee: Norma Bagatella Flores (FFIA-U. Veracruzana), Heriberto Castilla Valdés (CINVESTAV-U. Zacatenco), Lorenzo Díz Cruz (FCFM-BUAP), Juan José Godina Nava (CINVESTAV-U. Zacatenco), Gerardo Herrera Corral (CINVESTAV-U. Zacatenco), German Mandujano Vallejo (FFIA-U. Veracruzana), Miguel Ángel Pérez Angón (CINVESTAV-U. Zacatenco), Efraín Rojas Marcial (FFIA-U. Veracruzana) and Carlos Vargas Madrazo (FFIA-U Veracruzana). Many thanks also to our Conference Secretaries Patricia Carranza and Soledad López for the efficiency with which they carried out their job and their dedication. Special thanks go to María Guadalupe Colorado Hernández and Javier Ignacio Fragoso Tizapan, whose help in carrying out the School was essential, without their collaboration this School would not have been the same. We take this opportunity to thank most warmly all the speakers for delivering excellent lectures which made this event a success. Moreover, to our utmost delight, the students participated very enthusiastically and we hope that this school will contribute considerably towards their academic development. The future of scientific endeavour always depends upon the students. Adnan Bashir (IFM-UMSNH) Jens Erler (IF-UNAM) Rául Hernández (FFIA-UV) Myriam Mondragón (IF-UNAM) Luis Villaseñor (IFM-UMSNH)

Metronidazole and clarithromycin resistance in Helicobacter pylori determined by measuring MICs of antimicrobial agents in color indicator egg yolk agar in a miniwell format. The Gastrointestinal Physiology Working Group of Universidad Peruana Cayetano Heredia and the Johns Hopkins University.  

PubMed Central

Resistance of Helicobacter pylori to metronidazole often causes failure of commonly used combination drug treatment regimens. We determined the MICs of metronidazole and clarithromycin against 18 H. pylori strains from Peru using tetrazolium egg yolk (TEY) agar. The MIC results obtained by agar dilution with petri dishes were compared with the results found through a miniwell format. The results of the two protocols for measuring drug susceptibility differed by no more than 1 dilution in all cases. On TEY agar, bright-red H. pylori colonies were easy to identify against a yellow background. Sixty-one percent (11 of 18) of the strains were resistant to metronidazole (MIC, > or = 4 micrograms/ml) and 50% (9 of 18) were resistant to clarithromycin (MIC, > or = 0.125 micrograms/ml), whereas none (0 of 5) of the strains tested were resistant to tetracycline (MIC, > or = 1 micrograms/ml). Thus, the prevalence of metronidazole and clarithromycin resistance in Peru is higher than that in developed regions of the world. The miniwell plate with TEY agar allows easy H. pylori colony identification, requires about one-third less of the costly medium necessary for petri dish assaying, conserves space, and yields MICs equivalent to those with agar dilution in petri dishes.

[Distribution of financial resources according to the productivity (determined by bibliometry) in the Medical Research Laboratories of the Hospital das Clínicas da Faculdade de Medicina da Universidad de São Paulo (Brazil)].  


A challenge that research managers have to face is how to "reallocate" agency budgets in order to bring them in line with the results of performance reviews. Research policies must develop a strategic plan describing their goals, devise yardsticks to measure their progress, and tie that performance to allocate research funds with some degree of priority. Though Brazil already has a substantial presence in world's science, scientific enterprise must be used to strengthen it. The first step should be to raise standards in Brazilian science by concentrating the resources on supporting excellence. A strategy to judge biomedical research productivity should include tactics to disclose whether the resulting publications have appeared in the field's most respected, peer-reviewed journals. A pilot project to road-test the above-discussed ideas on performance measurements was conducted at the Laboratories of Medical Research (Clinical Hospital, University of São Paulo School of Medicine). These Laboratories perform a vast proportion of biomedical research at the country's largest University. This article illustrates that confidence in fairness and consistency with which funds are now being allocated has helped to improve productivity, thus showing that this strategy is fruitful.

Present Status of Historical Seismicity Studies in Colombia and Venezuela  

NASA Astrophysics Data System (ADS)

After the publication of the SISRA (CERESIS-1985) regional project, a unified catalog of seismic parameters and intensities for South America, researchers in historical seismicity have continued advancing on different scales in the area of this study of seismic hazard. The most important initiatives carried out in this area in Colombia and Venezuela can be grouped as follows: a) Reviews of destructive earthquakes in national and international historic archives, principally by Altez and FUNVISIS in Venezuela and Espinosa, Salcedo, and Sarabia et al in Colombia, leading to the preparation of seismologic catalogues, scientific and dissemination articles, reports, books, among others. b) Organization and systematization of historic information to develop public domain data bases and information, specifically the Historic Seismologic Teleinformation System in Venezuela, carried out between 2004 and 2008 under the coordination of Christl Palme and accessible on-line: As well, the "Historia Sísmica de Colombia 1550-1830" (Seismic History in Colombia 1550-1830) data base, in CD-ROM, by Espinosa Baquero (2003) and the historic seismicity information system of Colombia (Servicio Geológico Colombiano-Universidad Nacional de Colombia), published on the internet in 2012: c) Macroseismic studies for the development of intensity attenuation equations and the quantification and revaluation of basic historic earthquake parameters using isoseismal maps (Rengifo et al., Palme et al., Salcedo et al., among others) and procedures such as Boxer and Bakun & Wentworth (Palme et al., Dimaté, among others), which have produced significant changes in the parameters of some of the large earthquakes. d) Symposiums of researchers to promote interest and development in the discipline, including Jornadas Venezolanas de Sismología Histórica (Venezuelan Congress of Historical Seismology), held periodically between 1997 and 2012, the year of the sixth edition. As well, national and international research groups have been formed to work actively on global projects, such as the Geophysics Laboratory of Universidad de Los Andes in Venezuela. In the future, international groups will be formed to jointly treat issues including localization and size of destructive events along borders, common scales for the evaluation of intensities, integrated data bases, etc. Additionally the methods employed will be validated by paleoseismology, neotectonics and instrumental seismicity, among others.

Evolution of the Earthquake Catalog in Central America  

NASA Astrophysics Data System (ADS)

Central America (CA) is known as a seismically active region in which several historic destructive earthquakes have occurred. This fact has promoved the development of seismic hazard studies that provide necessary estimates for decision making and risk assessment efforts, requiring a complete and standardized seismic catalog. With this aim, several authors have contributed to the study of the historical seismicity of Central America (e.g. Grases, Feldaman; White y Harlow, 1993; White et al. 2004; Ambraseys y Adams, 2001; Peraldo y Montero, 1999), who complied historical data. A first catalogue was developed by Rojas (1993) that comprises the 1522 to 1993 period. This information was integrated in 2007, together with data from the International Seismological Centre (CASC) and the national catalogs of CA countries in a new regional catalogue. Since 2007 a continuous effort has been done in order to complete and update this CA earthquake catalog. In particular, two workshops were held in 2008 and 2011 in the Universidad Politécnica de Madrid (Spain), joining experts from the different CA countries who worked each one in its own catalogue covering the entire region and the border with northwestern Colombia and southern Mexico. These national catalogues were later integrated in a common regional catalogue in SEISAN format. At this aim it was necessary to solve some problems, like to avoid duplicity of events, specially close to the boundaries, to consider the different scales of magnitude adopted by different countries, to take into account the completeness by the different national networks, etc. Some solutions were adopted for obtaining a homogenized catalogue to Mw, containing historical and instrumental events with Mw > 3.5 from 1522 up to 2011. The catalogue updated to December 2007 was the basis for the first regional hazard study carried out by Benito et al., (2011) as part of the collaborative RESIS II project under coordination of NORSAR. The ones updated to 2011 is been used in a new seismic hazard study for the entire region. The responsable institutions of each CA country are: INSIVUMEH in Guatemala; Servicio Nacional de Estudios Territoriales, (SNET) in El Salvador; Red Sismológica National-RSN and Observatorio Sismológico and Vulcanológico de Costa Rica-OVSICORI, Observatorio Sismológico de la Universidad de Panama-UPA and Centro Sismológico de America Central, CASC This catalog is a very useful tool to conduct regional or local seismic hazard studies.

Lesson's-learned from a 2003-2006 USA-Honduras NGO and University Geosciences Education Partnership in Land use Land / Land Cover Change Analysis using Remote Sensing and GPS  

NASA Astrophysics Data System (ADS)

Between 2004 and 2006 the Loma Linda University ESSE21 Mesoamerican Project (Earth System Science Education for the 21st Century) collaborated with a series of academic, NGO (nongovernmental) and government agencies, including a USAID (United States Agency for International Development) integrated environmental resource management project to: a) build the human and technical capacity of local partners in the use of geospatial technologies, e.g. GIS, GPS, Remote Sensing, b) improve their capacity to apply these tools to biodiversity, health, sustainability, protected-area management, and other NRM (Natural Resource Management) decision-making needs and problems, and c) establish long term institutional relationships for teacher/student exchange, including development of joint curricula and research projects focused on health geoinformatics as well as sustainable development. Much of this has contributed toward a new "geotourism" effort adopted by Honduras called the SAVE Honduras strategy (Scientific, Academic, Volunteer, Educational). A central element of this initiative is to increase joint collaborative research and learning together by students and faculty at US universities working with Honduran institutions (private and public). See SAVE Strategy page = In the presentation we describe our experience over the last three years collaborating with key partners such as the Central American Observatory of Suyapa based at the UNAH (Universidad Nacional Autónoma de Honduras) which has opened a new GIS/Remote Sensing Laboratory. We also collaborated closely with CURLA (Centro Universitario Regional del Litoral Atlántico) located near La Ceiba--a land grant-type institution- -to support outreach and extension activities by students and staff to local-level NGOs and community groups dealing with conservation, hazards mitigation, biodiversity, fisheries and related problems. We have also participated in joint "informal education" efforts doing environmental and ecotourism outreach with groups such as the Hugh Parkey Foundation and EarthWatch Institute in Belize and others in Honduras such as FUCSA (Fundacion Cuero y Salado), FUPNAPIB (Fundacion Parque Nacional Pico Bonito), REHDES (Red Ecologista Hondurena para el Desarrollo Sostenible), and SMBC (Sociedad Mesoamericana para la Biologia y Conservacion). See more about the projects on water resources, herpetofauna on the Pacific coast, and the West Indian manatee at: Lessons learned about designing, organizing, implementing, and financing such geosciences educational partnerships will be presented as well as describing "next steps". Suggestions about how other universities could join with us will be also proposed.

Karstic Phenomena Susceptibility Map of MÉXICO  

NASA Astrophysics Data System (ADS)

Approximately 20% of the territory of México is underlain by karstifiable rocks, mostly limestones and in lesser proportions gypsum. The majority of these rocks are distributed along the eastern and southern Sierra Madre, the state of Chiapas and the Yucatán peninsula. Differences in geological structure, climate and geomorphic history have resulted in a great variety of karstic landscapes and types of forms. Several important population centers, including large cities with several million inhabitants and numerous smaller towns are built on karstic terrains and obtain their water supplies from karstic aquifers and/or dispose of their waste products on this type of terrain. Severe problems of waste disposal and aquifer contamination have occurred. Additionally, numerous instances of catastrophic collapse and formation of karstic sinkholes have been registered in the Mexican territory, which have affected many communities, roads and other infrastructure, and have even cost several lives. Lack of knowledge of the special characteristics of karstic terrains and their distribution has compounded these problems. As a first approach to these issues, the existing map of Mexican karst (Espinasa-Pereña, 2007) was modified according to the geotechnical classification proposed by Waltham & Fookes (2003). An important consideration taken into account is the difference in speed of development of karstic features depending on lithology, which makes karst developed in gypsum much more hazardous than limestone karst, and also the degree of soil coverage and the types of sinkholes developed on the cover. Also taken in consideration are the differences between karst developed in the Sierra Madre, with rocks highly deformed and fractured, and karst developed on the Yucatán peninsula with almost negligible deformation of the rocks. The resulting map will be useful to Civil Protection authorities as a tool in prognosticating possible affectations due to karstic phenomena.

Updated Colombian Seismic Hazard Map  

NASA Astrophysics Data System (ADS)

The Colombian seismic hazard map used by the National Building Code (NSR-98) in effect until 2009 was developed in 1996. Since then, the National Seismological Network of Colombia has improved in both coverage and technology providing fifteen years of additional seismic records. These improvements have allowed a better understanding of the regional geology and tectonics which in addition to the seismic activity in Colombia with destructive effects has motivated the interest and the need to develop a new seismic hazard assessment in this country. Taking advantage of new instrumental information sources such as new broad band stations of the National Seismological Network, new historical seismicity data, standardized global databases availability, and in general, of advances in models and techniques, a new Colombian seismic hazard map was developed. A PSHA model was applied. The use of the PSHA model is because it incorporates the effects of all seismic sources that may affect a particular site solving the uncertainties caused by the parameters and assumptions defined in this kind of studies. First, the seismic sources geometry and a complete and homogeneous seismic catalog were defined; the parameters of seismic rate of each one of the seismic sources occurrence were calculated establishing a national seismotectonic model. Several of attenuation-distance relationships were selected depending on the type of seismicity considered. The seismic hazard was estimated using the CRISIS2007 software created by the Engineering Institute of the Universidad Nacional Autónoma de México -UNAM (National Autonomous University of Mexico). A uniformly spaced grid each 0.1° was used to calculate the peak ground acceleration (PGA) and response spectral values at 0.1, 0.2, 0.3, 0.5, 0.75, 1, 1.5, 2, 2.5 and 3.0 seconds with return periods of 75, 225, 475, 975 and 2475 years. For each site, a uniform hazard spectrum and exceedance rate curves were calculated. With the results, it is possible to determinate environments and scenarios where the seismic hazard is a function of distance and magnitude and also the principal seismic sources that contribute to the seismic hazard at each site (dissagregation). This project was conducted by the Servicio Geológico Colombiano (Colombian Geological Survey) and the Universidad Nacional de Colombia (National University of Colombia), with the collaboration of national and foreign experts and the National System of Prevention and Attention of Disaster (SNPAD). It is important to stand out that this new seismic hazard map was used in the updated national building code (NSR-10). A new process is ongoing in order to improve and present the Seismic Hazard Map in terms of intensity. This require new knowledge in site effects, in both local and regional scales, checking the existing and develop new acceleration to intensity relationships, in order to obtain results more understandable and useful for a wider range of users, not only in the engineering field, but also all the risk assessment and management institutions, research and general community.

Volcanic Risk Perception in Five Communities Located near the Chichón Volcano, Northern Chiapas, Mexico  

NASA Astrophysics Data System (ADS)

The Chichón volcano (17° 19’ N and 93° 15’ W) is located in the state of Chiapas, Mexico. This volcano is classified by UNESCO as one of the ten most dangerous volcanos in the world. The eruptions of March and April in 1982 affected at least 51 communities located in the surroundings of the volcano and caused the death of about 2000 people. In this work we evaluate the risk perception in five communities highly populated: Juárez, Ostuacán, Pichucalco, Reforma and Sunuapa. We selected these communities because they have a high possibility to be affected by a volcanic eruption in the future. Our survey was carried out during February and March 2006. A total of 222 families were interviewed using a questionnaire to measure risk perception. These questionnaires retrieved general information as how long people had been living there and their reasons to do so; their experiences during the 1982 events, their opinion about the authorities participation and their perception of volcanic risk; the plans of the community for disaster prevention and mitigation. Some of the most important results are: (1). People perceive a very low volcanic risk and the 70% of interviewees believe that a new eruption in the future is almost improbable because it happened in 1982. This result is particularly interesting because, according to the state government, more than 100,000 inhabitants will be directly affected in case of a new similar eruption; (2). About 95% of the population do not know the current activity of the volcano and consider that the authorities do not inform properly to their communities; (3). The response of the authorities during the events of 1982 was ranked as deficient mainly because they were unable provide shelters, storage facilities, food as well as medicine and health care access; (4). Approximately 60% of the community will accept to be re-located again in case of a new eruption; (5). About 70% of the population will not accept to be re-located because they do not know any plan, strategy, emergency schemes or shelters locations no even evacuation routes. In conclusion, during the 1982 eruption the risk perception of the population played an important role in the social impact on the region. We believe that if the population had had a proper perception of their volcanic risk, the number of casualties would have been lower. Thus, the present low volcanic risk perception of the five studied communities can be considered as an important element of vulnerability. Frances Rodríguez-VanGort1 and David A.

Sampling strategy for a core collection of Peruvian quinoa germplasm.  


Quinoa (Chenopodium quinoa) is an Andean crop with a high potential for cultivation under temperate agricultural conditions. A new quinoa cultivar for such an environment requires plant characteristics that may be available primarily largely in genetic resources held in gene banks. A core collection may simplify management and enhance the utilisation of quinoa genetic resources. This paper describes the development of a core subset of the whole quinoa gene bank (1029 accessions) of the Universidad Nacional del Altiplano (UNAP). All accessions available in this gene bank have location and altitude descriptors and a partial description for qualitative and quantitative descriptors. The core collection (103 accessions) contains chosen ecotypes or landraces that capture most of the genetic variability available in this Peruvian germplasm. The accessions were selected for the core collection based on a geographically stratified non-overlapping sampling procedure. The number of accessions that were allocated to the core subset was determined using a proportional method adjusted by the relative importance of the quinoa crop in each geographical cluster as determined by its acreage. The sampling method also considered the morphological diversity within four geographical clusters of at least 100 accessions. The multivariate pattern of morphological variation was defined within each of these clusters by independent principal component analyses. A comparison of phenotypic diversity between the entire collection and its core subset confirmed that the proper sampling strategy for this core collection of Peruvian quinoa germplasm had been applied. The most important phenotypic correlations between quantitative descriptors observed in the entire collection, which may be under the control of co-adapted gene complexes, were also preserved by the core collection. The most comprenhensive quinoa core collection should consider accessions from other gene banks in Bolivia and Ecuador, a few accessions from coastal Chile and wild sympatric cross-compatible Chenopodium species. This core collection will be a point of entry to the proper exploitation of the genetic resources available in respective quinoa gene banks. PMID:24710887

Georadar Archaeological Prospection at the Historical Center of the Merida City, Yucatan, Mexico.  

NASA Astrophysics Data System (ADS)

This paper shows the results of the georadar archaeological prospection carried out by the Laboratorio de Prospección Arqueologica from the Instituto de Investigaciones Antropologicas (IIA) of the Universidad Nacional Autonoma de Mexico (UNAM) verifing the archaeological and historical information recovered by the Departamento de Patrimonio Arqueologico y Natural del Municipio (DPANM) del Ayuntamiento de Merida en el Centro Histerico de la Ciudad de Merida under a joint project. The Historical Center of Merida has been classified as a "zone of high patrimonial value" after the topographic data and the historical documents recovered showed a long-term occupation, non interrupted since pre-Columbian times, when T Ho was the great capital of the northern region of the Maya area. For the rehabilitation program of the Historical Center of Merida has been a great priority to verify the existence of archaeological remains, pre-Columbian or colonial, under the present streets, gardens and plazas that could be damaged during the public infrastructure works. In order to prevent any damage to the patrimony a large georadar study was carried out pulling 200 and 400 MHz antennas of the GSSI SIR System 2 for 16500 m of the city streets, focusing in the areas where infrastructure works were imminent. After the analysis of the radar data it was possible to build up a map with the location of the most noticeable archaeological remains under the pavement of the streets that confirmed many of the topographic and documental proposed places. As a final result, by the first time a city government has available information to take present urban decisions, while preventing the damage to the archaeological patrimony of the same city.

The Yale/San Juan Southern Proper Motion Program  

NASA Astrophysics Data System (ADS)

The SPM is based on photographic plates taken at our observatory at El Leoncito, Argentina and will yield absolute proper motions and positions to magnitude B 19 for approximately 1 million stars south of declination -20 degrees. The SPM is a joint program between the Yale Southern Observatory and the Universidad Nacional de San Juan, Argentina. The SPM Catalog 2.0 provides positions, absolute proper motions, and photographic BV photometry for over 320,000 stars and galaxies. All objects contained in the SPM 1.0 Catalog (the South Galactic Pole region) are also included in this version. Note that SPM 1.0 has been replaced by SPM 1.1 which has slightly different astrometry (mostly proper motions) due to refinement of the magnitude equation correction in the SPM 2.0 Catalog. The Catalog covers an area of 3700 square degrees in an irregularly bounded band between declinations of -43 and -22 degrees, but excluding fields in the plane of the Milky Way. Stars cover the magnitude range 5 < V < 18.5. The standard errors for the best measured stars are as follows: 20 mas for positions in each coordinate; 2 mas/yr for absolute proper motions and 0.05 mag in B and V bandpasses. In addition to the Catalog, a list of CCD calibrating sequences in BV is provided. It contains 7783 stars. The new feature of the Catalog is an extensive list of cross-identifications with external special catalogs which include all major astrometric catalogs and a large number of astrophysically interesting objects. The Catalog is available on the WWW at Our web-site contains several useful plots showing the sky coverage, error distribution, a quick comparison with the Hipparcos proper motions, etc.

Geodiversity and geoheritage research and education in Mexico  

NASA Astrophysics Data System (ADS)

Geosites, geomorphosites, geoheritage, geodiversity and other related research and educational fields have been absent in the curricula of Mexican universities, although some efforts to consider those topics started in 2004 (Garrido, 2004). In the case of Mexico, Geographers have been the main promoters of the study of geoparks and, more recently, geomorphosites; studies on geosites have been developed by geologists although, in all cases, concrete examples are very limited in number since no systematic work has been proposed. A general educational project to promote the study and research on Geoparks (including Geodiversity, Geoconservation, Geosites and Geomorphosites) has been recently proposed atthye Universidad Nacional Autónoma de México. The main components of this project include: a) Teaching. Starting only this year, the School of Geography (undergraduate level) incorporated for the first time a subject specifically related to geoparks, geosites and geomorphosites. The subject is complemented with other, more specifically related to the land use management, cartography and (geo)tourism; b) Research. At the Institute of Geography, projects to conduct systematic research on geoparks and related items has just started; c) Natural heritage promotion and Geotourism. In a national context, where tourism has received official attention and extraordinary financial support, Geotourism plays an important part of the educational project. A proposal has been submitted to the Ministry of Tourism so that students are expected to get an official certificate to carry out activities related to the promotion of the natural heritage as a (Geo)tourist Guide. Among general goals, the creation of regional and national networks of geoparks, and participation in international efforts (geosites and geomorphosites lists), are also considered.

Event Clustering: Accuracy and Precision of Multiple Event Locations with Sparse Networks  

NASA Astrophysics Data System (ADS)

In the last 15 years passive PASSCAL experiments have been fielded on every continent. Most of these deployments were designed to record teleseismic or large local seismic events to infer crustal and mantle structure. However, the deployments inevitably record small, local seismicity. Unfortunately, the configuration of the experiments are not optimal for location (typically the stations are arranged in linear arrays), and the seismicity is recorded at a very limited number of stations. The standard location procedure (Geiger's method) is severely limited without a detailed crustal model. A number of methods have been developed to improve relative location precision, including Joint Hypocenter Determination (JHD) and Progressive Multiple Event Location (PMEL). In this study we investigate the performance of PMEL for a very sparse network where there appears to be strong event clustering. CHARGE is a passive deployment of broadband seismometers in Chile and Argentina, with a primary focus of investigating the changes in dip along the descending Nazca Plate. The CHARGE stations recorded a large number of small, local events in 2000-2002. For this study events were selected from the northern profile (approximately along 30o S) in Chile. The events look similar, and appear to be clustered southeast of the city of La Serena. We performed three sets of experiments to investigate precision: (1) iterative Master Event Corrections to measure the scale length of clusters, (2) PMEL locations, and (3) PMEL locations using a cross-correlation to determine accurate relative phase timing. The analysis shows that for the PMEL experiment clusters must occupy an area of 600 km2 for the results to be consistent. We will present a method to estimate the precision errors based on bootstrapping. Charge Team: S. Beck, G. Zandt, M. Anderson, H. Folsom, R. Fromm, T. Shearer, L. Wagner, and P.

Enhancing Diversity In The Geosciences; Intensive Field Experience In USA And Mexico For Middle And High School Teachers Serving Large Hispanic Populations.  

NASA Astrophysics Data System (ADS)

To encourage Hispanic participation and enrolment in the geosciences and ultimately enhance diversity within the discipline, we recruited ten middle and high school science teachers serving large Hispanic populations (60-97%) for a paid three-week field experience supported by an NSF Opportunities for Enhancing Diversity in the Geosciences grant. In 2006, the field experiences focused on volcanic events and the water problems of the Central part of Mexico. In 2008, the field experiences focused on karstic and hydrogeological conditions of the Yucatan Peninsula. In addition to the geological aspects of the fieldwork experience, the trip to Mexico exposed the teachers to a social environment outside of their community where they interacted with a diverse group of scientists from the Universidad National Autonoma de Mexico (UNAM), Centro de Investigacion Cientifica de Yucatan (CICY) and Centro Nacional de Desastres (CENAPRED). A key part of this project was the encounter between American and Mexican teachers that included a day of presentations, panel discussion and some class-room activities. Direct interaction between the cooperating teachers and the American and Mexican geoscientists provided actual scientific research experiences to educate and to help dispel misconceptions the teachers themselves may have had about who geoscientists really are and what they do. Teachers of the 2006 group produced educational materials from their field experiences and presented these materials at professional conferences. We measured the efficacy of these activities quantitatively via pre- and post-tests assessing confidence levels, preconceptions and biases, NIU staff observations of participants in their home institutions, and evaluations of participants' field books and pedagogical materials. We present these data here and identify specific activities that are both effective and efficient in changing teacher behaviours and attitudes enabling them to better connect with their Hispanic students in their Geoscience classrooms. Post experience activities of the 2008 group will build on these results.

Traditions of the Sun, One Model for Expanding Audience Access  

NASA Astrophysics Data System (ADS)

The Internet is a powerful tool with which to expand audience access, bringing students, teachers and the public to places and resources they might not otherwise visit or make use of. We will present Traditions of the Sun, an experiential Web site that invites exploration of the world's ancient observatories with special emphasis on Chaco Culture National Historic Park in the Four Corners region of the US and several sites in the Yucatan Peninsula in Mexico. Traditions of the Sun includes resources in English and Spanish along with a unique trilingual on-line book, "Traditions of the Sun, A Photographic Journal," containing explanatory text in Yucatec Maya as well. Traditions of the Sun offers rich opportunities for virtual visits to ancient sites used for solar observing while learning about current NASA research on the Sun and indigenous solar practices within a larger historical and cultural context. The site contains hundreds of photographs, historic images and rich multimedia to help tell the story of the Sun-Earth Connection. Visitors to the site can zoom in on the great Mayan cities of Chichen Itza, Uxmal, Dzibilchaltun, and Mayapan to learn about Mayan astronomy, history, culture, and science. They can also visit Chaco Canyon to watch sunrise over Pueblo Bonito on the summer solstice, take a virtual reality tour of the great kiva at Casa Rinconada or see panoramic vistas from Fajada Butte, an area which, for preservation purposes, is restricted to the public. Traditions of the Sun provides one model of how exploration and discovery can come to life for both formal and informal audiences via the Internet. Traditions of the Sun is a collaborative project between NASA's Sun-Earth Connection Education Forum, the National Park Service, Instituto National de Antropologia e Historia, Universidad Nacional Autonoma de Mexico, and Ideum.

Decadal changes and delayed avian species losses due to deforestation in the northern Neotropics  

PubMed Central

How avifauna respond to the long-term loss and fragmentation of tropical forests is a critical issue in biodiversity management. We use data from over 30 years to gain insights into such changes in the northernmost Neotropical rainforest in the Sierra de Los Tuxtlas of southern Veracruz, Mexico. This region has been extensively deforested over the past half-century. The Estación de Biología Tropical Los Tuxtlas, of the Universidad Nacional Autónoma de México (UNAM), protects a 640 ha tract of lowland forest. It became relatively isolated from other forested tracts between 1975 and 1985, but it retains a corridor of forest to more extensive forests at higher elevations on Volcán San Martín. Most deforestation in this area occurred during the 1970s and early 1980s. Forest birds were sampled on the station and surrounding areas using mist nets during eight non-breeding seasons from 1973 to 2004 (though in some seasons netting extended into the local breeding season for some species). Our data suggested extirpations or declines in 12 species of birds subject to capture in mist nets. Six of the eight species no longer present were captured in 1992–95, but not in 2003–2004. Presence/absence data from netting and observational data suggested that another four low-density species also disappeared since sampling began. This indicates a substantial time lag between the loss of habitat and the apparent extirpation of these species. Delayed species loss and the heterogeneous nature of the species affected will be important factors in tropical forest management and conservation.

This mining activity has been intensively developed since 2005. There are currently 7 large-scale mining projects in that area. The coal industry has strongly impacted not only the ecosystems, but also the neighboring communities around the coal mines. The main goal of the research work was to characterize spatial and temporal variations of particulate matter (total suspended particulates - TSP - and particulate matter below 10 ?m - PM10) as measured at various air quality monitoring stations in Cesar's coal industry region as well as to study the relationship between these variability and meteorological factors. The analysis of the meteorological time series of revealed a complex atmospheric circulation in the region. No clear repetitive diurnal circulation patterns were observed, i.e. statistical mean patterns do not physically represent the actual atmospheric circulation. We attribute this complexity to the interdependence between local and synoptic phenomena over a low altitude, relatively flat area. On the other hand, a comparison of air quality in the mining area with a perimeter station indicates that coal industry in central Cesar has a mayor effect on the levels of particulate matter in the region. Particulate matter concentration is highly variable throughout the year. The strong correlation between TSP and PM10 indicates that secondary aerosols are of minor importance. Furthermore, particle concentrations are the highest in January and February, being the correlation between the TSP and PM10 measurements not as strong during this time period. This could be associated with the spatial and temporal variability of wet deposition as well as a larger mechanical and eolic resuspension of particles. We found that precipitation drastically reduces the levels of particulate matter. In order to describe the effect of wet deposition, a mathematical model was developed based on a first order relaxation proportional to the precipitation rate. Daily average concentrations and daily accumulated precipitation were used in this model, which showed high concentration reductions even for low precipitation levels essentially for all stations. Monthly precipitation values showed a better correlation with TSP concentrations. Finally, we found evidence of a significant decrease in global radiation due to particulate matter, particularly during the dry season, which could potentially affect farming and agricultural activities in the region.

Complex systems represent one of the richest and more fascinating fields of current scientific research. The reason behind this is the important role that the properties of complex systems and materials play in a variety of different but overlapping areas in physics, chemistry, biology, mathematics, and social sciences, like medicine and economy. Such unusually broad research field is, therefore, of primary interest nowadays in pure science and technology. The role of statistical physics in this new field of complex systems has been present since its onset and it has been accelerating recently. Methods developed for studying ordering phenomena in simple systems have been generalized for application to more complex forms of matter (polymers, biological macromolecules, glasses, etc) and complex processes (e.g. chaos, turbulence, economy, jamming, biological processes). In particular, many different phenomena (considered in the past to belong to separate research fields) have now a common description. Pillars of such a description are the concepts of scaling and universality. The International Conference on `Scaling Concepts and Complex Systems' (a satellite meeting of STATPHYS21) was devoted to give an overview on recent developments around these two concepts. The Conference took place in Merida, Yucatan, Mexico, in July 9-14 2001. The meeting was held in the Gordon Conference style and was attended by about 100 scientists, it covered a large variety of theoretical and experimental research topics of current interest in complex systems and materials. The meeting consisted of a total number of about 40 invited and contributed talks and a poster session. The topics covered included: scaling behaviour, supra-molecular systems, aggregation, aggregation kinetics, growth mechanisms, disordered systems, soft condensed matter (polymers, biological polymers, bio-colloids, gels, colloids, membranes and interfacial phenomena), granular matter, phase separation and out-of-equilibrium dynamics, non-linear dynamics, chaos, turbulence and chaotic dynamics. The present issue contains a substantial number of the invited and contributed talks presented at the meeting. We made an effort to arrange these papers with an order similar to that of presentation during the meeting. It is our pleasure to thank the scientific committee, all the speakers, the session chairs and all participants who contributed to the success of the conference. We are grateful to the Bonino-Pulejo Foundation (Messina-Italy), and to the President On. Nino Calarco, for the Patronage and the enthusiastic support. Our thanks goes also for the Messina University, the INFM (Istituto Nazionale per la Fisica della Materia, Italy), the Consejo Nacional de Ciencia y Tecnología (CONACyT, Mexico) and the Universidad Nacional Autonoma de Mexico (UNAM). The Conference was sponsored by the INFM-Sec.C, CONACyT, UNAM, the Bonino-Pulejo Foundation which contributed financial support to participants and to the publication of the present issue. We are grateful to them for the support. Last, but not the least, we express our warmest gratitude to all the members of the local organizing committee for their assistance and for the work spent in organizing this meeting and especially to Professor~Alberto Robledo for his valuable advice.

Obituary -- Salvador González Bedolla  

NASA Astrophysics Data System (ADS)

It is with great sadness that I must communicate the passing of our colleague Salvador Félix González Bedolla. The observational astronomers of the Observatorio Astronómico Nacional owe much to his pioneering effort at San Pedro Mártir, work that formed him as an astronomer, and helped him become one of the best photometric observers in México and, at the Instituto de Astronomóa of the UNAM, the academic technician with the highest productivity of articles derived from observations at the OAN. Salvador was an excellent student. He obtained the highest achievement award (Gabino Barreda) in high school, studied physics at the Universidad Nacional Autónoma de México (UNAM) and also finished the credits for his Master's degree in Physics with only his thesis separating him from his degree, an act which was constantly put off until his death. He began his career in Astronomy in 1973 under Dr. Eugenio Mendoza. Later he worked with Josef Warman in the observation of short period stars in the Observatorio `José Arbol y Bonilla'' in Zacatecas, México. I then began working continuously with him in this field of research which, thanks to his great work capacity, produced very good results. He continued in these fields of research not only within the Institute of Astronomy, but also in other research facilities, especially two: With the variable group from the Observatory at Nice, France, beginning in 1985, specializing in the pulsation of early stars. His main interest was in the ? Cep stars and in the possibility of relating these stars to the new types of variables (such as the OB stars, the `53 Per' variables, the `ultrashort' period and the ``slow'' and Be variables) discovered near this zone. Hence, in view of this, his efforts were aimed at monitoring the stars that belong to these new groups in order to discover if they are really different from the classical ? Cep stars. Moreover, beginning in 1984, Salvador began working with a group of astronomers from the Instituto de Astronomóa de Andalucóa, Spain. His participation was active and indispensable in international campaigns which were carried out to study short period pulsators with very complex sets of frequencies using an analysis of light curves. Thanks to his observations, which were quite reliable, the pulsational and astrophysical characteristics of a great number of them have been resolved. Also, during these investigations, many new pulsators were discovered, especially Delta Scuti stars. Salvador also dedicated many years to teaching. Beginning in 1972, he taught physics and chemistry at the Colegio de Ciencias y Humanidades of the UNAM where he also developed programs, evaluated candidates for teaching posts and published books about his specialities. His loss, a product of the senseless violence of modern life in México City, is mourned by the Instituto de Astronomóa, UNAM, since he always tried to develop his activities with a high degree of professionalism and with great enthusiasm. Salvador, your colleagues and friends miss you and your memory will always remain with us.

Mapping the complex kinematics of LL objects in the Orion nebula  

NASA Astrophysics Data System (ADS)

LL Orionis-type objects (LL objects) are hyperbolic bowshocks visible around young stars in the outer Orion nebula, many of which are also associated with curved, highly collimated jets. The bowshocks are clearly due to the supersonic interaction between an outflow from the young star and an environmental flow from the core of the nebula, but the exact nature of these flows has not yet been established. We present the first high-resolution optical spectra of two of these objects, LL 1 and LL 2, together with their associated Herbig-Haro (HH) jets, HH 888 and HH 505. We combine multiple long-slit echelle spectra in the H? 6563 Å and [N ii] 6584 Å lines to produce velocity maps of the two objects at a resolution of 4text{arcsec} × 2text{arcsec} × 11 {km s^{-1}}. The gas motions within both stellar bowshocks are of rather low velocity (10-20 km s-1), but there are important differences between the two objects. LL 1 shows a high degree of symmetry, whereas LL 2 has very asymmetric kinematics that seem to follow velocity gradients in the surrounding nebula. We also measure the line-of-sight velocity for multiple knots in the HH 888 and HH 505 jets, and combine our spectroscopy with new and existing proper-motion measurements to reconstruct the three-dimensional kinematics of the jets. The knot motions in both jets are very similar: both flows are inclined at 40° to 60° from the plane of the sky, with exclusively redshifted knots to the north and exclusively blueshifted knots to the south. In both cases, one also sees a deceleration along the length of the jets, from >200 km s-1 close to the respective stars down to <100 km s-1 farther out. The marked contrasts that we find between the kinematics of the jets and the kinematics of the stellar bowshocks are evidence that the two phenomena are not causally related. Regular patterns in the dynamic ages of the HH 505 knots imply periodic ejections on three different time-scales: 50, 12 and 4 yr. We use line ratios and photometry to measure electron densities and excitation/ionization conditions in the stellar bowshocks and jet knots. The LL 1 bowshock has a bright inner shell with density ?3000 cm-3 (compared with a local nebula density of ?1000 cm-3) and line ratios that are consistent with equilibrium photoionization models. The bowshock also has a fainter outer rim, where the line ratios show evidence of shock excitation. Many of the jet knots also show evidence for a shock contribution to their excitation and have densities from 1000 to 8000 cm-3. Based on observations obtained at the Observatorio Astronómico Nacional, San Pedro Mártir, Baja California, Mexico, which is operated by the Universidad Nacional Autónoma de México. Based on observations with the NASA/ESA Hubble Space Telescope, obtained at the Space Telescope Science Institute, which is operated by the Association of Universities for Research in Astronomy, Inc., under a cooperative agreement with the National Science Foundation. iraf is distributed by the National Optical Astronomy Observatories, which is operated by the Association of Universities for Research in Astronomy, Inc., under cooperative agreement with the National Science foundation. Velocities in the frame of the local standard of rest are obtained by subtracting 18.1 km s-1 from the heliocentric values. Traditionally, [O iii] is normalized by H? rather than H? in order to minimize the effects of extinction. In our case, the extinction is known to be low (Section 6), so the main effect of using H? instead is to shift the y-axis by the intrinsic Balmer decrement of ˜0.5 dex.

Field Courses for Volcanic Hazards Mapping at Parícutinand Jorullo Volcanoes (Mexico)  

NASA Astrophysics Data System (ADS)

During the last decades, Mexico has suffered several geologic phenomena-related disasters. The eruption of El Chichón volcano in 1982 killed >2000 people and left a large number of homeless populations and severe economic damages. The best way to avoid and mitigate disasters and their effects is by making geologic hazards maps. In volcanic areas these maps should show in a simplified fashion, but based on the largest geologic background possible, the probable (or likely) distribution in time and space of the products related to a variety of volcanic processes and events, according to likely magnitude scenarios documented on actual events at a particular volcano or a different one with similar features to the volcano used for calibration and weighing geologic background. Construction of hazards maps requires compilation and acquisition of a large amount of geological data in order to obtain the physical parameters needed to calibrate and perform controlled simulation of volcanic events under different magnitude-scenarios in order to establish forecasts. These forecasts are needed by the authorities to plan human settlements, infrastructure, and economic development. The problem is that needs are overwhelmingly faster than the adjustments of university programs to include courses. At the Earth Science División of the Faculty of Engineering at the Universidad Nacional Autónoma de México, the students have a good background that permits to learn the methodologies for hazards map construction but no courses on hazards evaluations. Therefore, under the support of the university's Program to Support Innovation and Improvement of Teaching (PAPIME, Programa de Apoyo para la Innovación y Mejoramiento de la Enseñanza) a series of field-based intensive courses allow the Earth science students to learn what kind of data to acquire, how to record, and process in order to carry out hazards evaluations. This training ends with hazards maps that can be used immediately by the authorities after proper review by peers. This project has been running for two years and hazards maps for the region of Parícutin and Jorullo volcanoes have been carried out. The students have been applying their knowledge and got results in a very short time and at the same time socially very important.

NASA Technical Reports Server (NTRS)

These images of HH 30 show changes over only a five-year period in the disk and jets of this newborn star, which is about half a million years old. The pictures were taken between 1995 and 2000 with the Wide Field and Planetary Camera 2 aboard NASA's Hubble Space Telescope. Astronomers are interested in the disk because it is probably similar to the one from which the Sun and the planets in our solar system formed. Hubble reveals an edge-on disk (located at the bottom of the images), which appears as a flattened cloud of dust split into two halves by a dark lane. The disk blocks light from the central star. All that is visible is the reflection of the star's light by dust above and below the plane of the disk. The disk's diameter is 450 astronomical units (one astronomical unit equals the Earth-Sun distance). Shadows billions of miles in size can be seen moving across the disk. In 1995 and 2000, the left and right sides of the disk were about the same brightness, but in 1998 the right side was brighter. These patterns may be caused by bright spots on the star or variations in the disk near the star. The dust cloud near the top of these frames is illuminated by the star and reflects changes in its brightness. The star's magnetic field plays a major role in forming the jets (located above and below the disk), which look like streams of water from a fire hose. The powerful magnetic field creates the jets by channeling gas from the disk along the magnetic poles above and below the star. The gaps between the compact knots of gas seen in the jet above the disk indicate that this is a sporadic process. By tracking the motion of these knots over time, astronomers have measured the jet's speed at between 200,000 to 600,000 miles per hour (160,000 and 960,000 kilometers per hour). Oddly, the jet below the disk is moving twice as fast as the one above it.

Relationship Between Precipitation Chemistry and Meteorological Parameters at a Urban Site in the North of Queretaro State  

NASA Astrophysics Data System (ADS)

A total of 50 wet precipitation samples were collected per event at the Juriquilla site from mid-May 2009 to the end of May 2010. The Juriquilla sampling site was located on the roof of the Geoscience Building, Universidad Nacional Autónoma de México, at the Juriquilla Campus in the city of Querétaro located at 20°41'58"N and 100°27'28" W, at 1920 meters above sea level (masl). Sampling was done in passive collectors that consisted of a high density polyethylene funnel connected to a 2-liter polyethylene bottle, supported by a rod 1.5 m above the roof. One of the collectors was used to take samples for trace metals. The analysis was done in soluble and insoluble fractions. Al, Ag, As, Cd, Cr, Cu, Hg, Mn, Ni, Pb, V and Zn were analyzed by atomic absorption spectroscopy with a graphite furnace accessory. The other collector was used to measure pH and major ions (SO4-2, Cl-, NO3-, Ca2+, Mg2+, Na+, K+ and NH4+) in the soluble fractions, because it was assumed that these ions are completely soluble in rainwater. The major ions SO4-2, Cl-, and NO3-, were analyzed by a Varian Model 2010 ion chromatograph; Ca2+, Mg2+, Na+ and K+ were determined by flame atomic absorption spectrometry and NH4+ by a UV spectrophotometer. In this study, synoptic maps were used to analyze the transport of air masses before rainfall, enabling back trajectories to be used to estimate the source region of pollutants. To understand the variety of synoptic weather conditions, data were associated with the corresponding air mass back trajectories calculated by the NOAA HYSPLIT model (Hybrid Single-Particle Lagrangian Integrated Trajectory Model). Back trajectory models have very simple advection schemes to calculate the previous position of an air parcel by using estimated wind speed and direction for the time period prior to arrival at the selected site. In this study, the origin of the air mass for an event was evaluated by a three-day back-trajectory before arrival to Queretaro. Mass back trajectories were calculated for 1000 and 2000 meters above ground level (MAGL), because winds at these levels should be a good approximation to the mean transport wind, since this pressure level frequently lies near the center of the transport layer. Finally, trajectories were classified by eight different directions according to the directions of the air masses before rainfall.

The Seismic Strong Motion Array Project (SSMAP) and the September 5, 2012 Mw=7.6 Nicoya, Costa Rica Earthquake  

NASA Astrophysics Data System (ADS)

Seismic gaps along the subduction zones are locations where large earthquakes have not occurred in a long time. The Cocos plate is subducting beneath the Caribbean plate in Costa Rica, and the Nicoya Peninsula, located in northwestern Costa Rica, has been identified as a seismic gap. The previous major earthquakes in Nicoya occurred on 1853, 1900 and 1950, which indicates about a 50-year recurrence interval for the characteristic earthquake cycle. Since 2006, the seismic strong motion array project (SSMAP) for the Nicoya Peninsula in northwestern Costa Rica has been composed of 10 sites with Geotech A900/A800 accelerographs (three-component) and GPS timing. Our digital accelerographs array has been deployed as part of our ongoing research on large earthquakes, including the potential Nicoya event, in conjunction with the Earthquake and Volcano Observatory (OVSICORI) at the Universidad Nacional in Costa Rica. From 2006 to 2012, 28 events were relocated using the SSMAP and OVSICORI data with moderate magnitudes (4 < Mw< 6.5), and were mainly located in Nicoya Peninsula region. On September 5, 2012, a Mw=7.6 earthquake occurred in the seismic gap and appears to be the expected event based on the 50 years recurrence interval, but was instead 62 years later. The main shock focal mechanism was thrust faulting, propagating downdip, of the Cocos plate in the Middle America trench with strike N54W and dip 20 degrees NE. The mainshock and 15 early aftershocks were relocated by using SSMAP, OVSICORI, and UCSC networks. The final location of the mainshock is 9.671 N and 85.878 W with a depth of 18 km. The maximum accelerations from two A900 stations perpendicular to the trench, Fortuna (distance 112km) and Pedernal (distance 128 km) are: 13.8% and 8.9 % g, respectively. In addition, the October 10 (MW 5.3) and 24(Mw 6.6) aftershocks recorded at Tamarindo (distances 40 km and 70 km, respectively) showed accelerations of 2.4% and 8.2% g; respectively. The mainshock acceleration data from SSMAP, University of Costa Rica, and National Electricity Institute networks were analyzed for a new attenuation relationship: Acceleration = -203 ln(R) + 1110 with M=7.6 and R = hypocentral distance.

Initiatives of Application of the Bakun-Wentworth's Method for the Estimation of Macroseismic Parameters in the Northern South America and the Caribbean Region  

NASA Astrophysics Data System (ADS)

The assessment of location, magnitude and uncertainties of great historical earthquakes is a key issue for understanding the seismic potential and PSHA of a region. In the last years independent techniques using only macrosesismic data points have been developed as, for example, the approach of Bakun and Wentworth (1997) or BW. This method has been largely applied in different tectonic contexts (Bindi et al., 2013), in different UE international projects and in estimations of location, magnitude and epistemic uncertainties (Bakun et al., 2011). We focus on some regional calibration initiatives in Northern South America and areas of the Caribbean Region. BW has been calibrated by Palme et al. (2005) and Choy et al. (2012) for earthquakes of the Mérida Andes and the Venezuela Central Regions. As well, BW calibrations have been proposed for the interandean Valley in Ecuador (Beauval et al., 2010), in the Hispaniola (Bakun et al, 2012) and for the northeastern Caribbean region (ten Brink et al., 2011). Preliminary BW calibration for the southeastern region of Cuba has been proposed by Gómez-Capera et al. (2012). Applications to historical earthquakes in Cuba have given encouraging results mainly for offshore events and are presented in the present study. We also present preliminary results for some earthquakes that have been recently studied in literature as for example the historical earthquakes of 1743 (Salcedo Hurtado and Gómez-Capera in press) and 1785 (Salcedo Hurtado and Castaño Castaño, 2011) which occurred close to Bogotá, BW method and intensity relationship of the literature were used. We present comparisons and sensibility analysis of the different relationships obtained in the region as well as uncertainty assessment. We also note that the magnitude parameter depends strongly on the regional calibration. Because of the availability of new macroseismic studies in Colombia (Servicio Geológico Colombiano y Universidad Nacional de Colombia, 2013; available online inórica/), Venezuela ( and Caribbean Region, in the future it is expected to propose models for macroseismic intensity attenuations of regional character especially in Colombia and in Venezuela in the Cumaná region. This region has a rich earthquake history. In this topic of the regional calibration of intensity attenuation relationships, the situation is challenging because several historical and recent earthquakes in this region are attributed to subduction zones. It is therefore necessary to involve focal depth. This is still an open problem.

Prevalence of dementia in Latin America, India, and China: a population-based cross-sectional survey  

PubMed Central

Summary Background Studies have suggested that the prevalence of dementia is lower in developing than in developed regions. We investigated the prevalence and severity of dementia in sites in low-income and middle-income countries according to two definitions of dementia diagnosis. Methods We undertook one-phase cross-sectional surveys of all residents aged 65 years and older (n=14?960) in 11 sites in seven low-income and middle-income countries (China, India, Cuba, Dominican Republic, Venezuela, Mexico, and Peru). Dementia diagnosis was made according to the culturally and educationally sensitive 10/66 dementia diagnostic algorithm, which had been prevalidated in 25 Latin American, Asian, and African centres; and by computerised application of the dementia criterion from the Diagnostic and Statistical Manual of Mental Disorders (DSM IV). We also compared prevalence of DSM-IV dementia in each of the study sites with that from estimates in European studies. Findings The prevalence of DSM-IV dementia varied widely, from 0·3% (95% CI 0·1–0·5) in rural India to 6·3% (5·0–7·7) in Cuba. After standardisation for age and sex, DSM-IV prevalence in urban Latin American sites was four-fifths of that in Europe (standardised morbidity ratio 80 [95% CI 70–91]), but in China the prevalence was only half (56 [32–91] in rural China), and in India and rural Latin America a quarter or less of the European prevalence (18 [5–34] in rural India). 10/66 dementia prevalence was higher than that of DSM-IV dementia, and more consistent across sites, varying between 5·6% (95% CI 4·2–7·0) in rural China and 11·7% (10·3–13·1) in the Dominican Republic. The validity of the 847 of 1345 cases of 10/66 dementia not confirmed by DSM-IV was supported by high levels of associated disability (mean WHO Disability Assessment Schedule II score 33·7 [SD 28·6]).

Magnetometry and archaeological prospection in Mexico  

NASA Astrophysics Data System (ADS)

Luis Barba Laboratorio de Prospección Arqueológica Instituto de Investigaciones Antropológicas Universidad Nacional Autonoma de México The first magnetic survey in archaeological prospection was published in 1958 in the first number of Archaeometry, in Oxford. That article marked the beginning of this applications to archaeology. After that, magnetic field measurements have become one of the most important and popular prospection tools. Its most outstanding characteristic is the speed of survey that allows to cover large areas in short time. As a consequence, it is usually the first approach to study a buried archaeological site. The first attempts in Mexico were carried out in 196. Castillo and Urrutia, among other geophysical techniques, used a magnetometer to study the northern part of the main plaza, zocalo, in Mexico City to locate some stone Aztec sculptures. About the same time Morrison et al. in La Venta pyramid used a magnetometer to measure total magnetic field trying to find a substructure. Some years later Brainer and Coe made a magnetic survey to locate large stone Olmec heads in San Lorenzo Tenochtitlan, Veracruz. Technology development has provided everyday more portable and accurate instruments to measure the magnetic field. The first total magnetic field proton magnetometers were followed by differential magnetometers and more recently gradiometers. Presently, multiple sensor magnetometers are widely used in European archaeology. The trend has been to remove the environmental and modern interference and to make more sensitive the instruments to the superficial anomalies related to most of the archaeological sites. There is a close relationship between the geology of the region and the way magnetometry works in archaeological sites. Archaeological prospection in Europe usually needs very sensitive instruments to detect slight magnetic contrast of ditches in old sediments. In contrast, volcanic conditions in Mexico produce large magnetic contrast between the igneous rocks and the sediments in archaeological context, thus the use of less sensitive instruments works fine for these conditions. Surveys in archaeological sites in Mexico during last 30 years have provided enough evidence that the best conditions to apply magnetic prospection is in lacustrine environment where the ancient inhabitants used igneous rocks as building material. These conditions has been more common than expected in the Trans volcanic Belt where most of the lakes were densely occupied in ancient times. Because most lakes were surrounded by quite recent volcanos, it was pretty common to use the basaltic and andesitic rocks to build the archaeological structures. In this contribution some of the most successful applications of the magnetic technique in archaeology will be shown to illustrate the possibilities of the magnetometry in archaeological prospection.

PREFACE: X Meeting on Recent Advances in the Physics of Fluids and their Applications  

NASA Astrophysics Data System (ADS)

The X Meeting on Recent Advances in Physics of Fluids and Related Applications (Fluids 2008) was held in Santa Fe, Argentina, on 19-21 November 2008. It belongs to a series of meetings that started in 1989 and has continued - except for just one occasion - every other year. Thus, the first meeting took place in the city of Tandil in 1989 followed by three events in the city of La Plata (1991-93-95), Tunuyán (Mendoza) in 1997, Paraná (Entre Rios) in 1999, Buenos Aires in 2001, Tandil in 2003 and Mendoza in 2006. These meetings gather together most of the people working in Fluid Mechanics and related problems in Argentina. The objective of the meetings is to provide a forum to facilitate the interactions between participants in a friendly academic atmosphere. This goal is achieved by means of lectures and technical presentations on different subjects and from different points of view, the only constraint being the current academic/technical interest. Applications usually deal with problems of local interest. In the present meeting a variety of lecture topics were presented, among them we might mention Capillary Hydrodynamics, Wetting, Density Currents, Instabilities, Elastic-Dynamics, Flows in Porous Media, Sediment Transport, Plasma Dynamics, etc. In particular, we would like to highlight the specially invited lectures given by Dr Ramon Cerro (Chemical and Material Engineering Department University of Alabama in Huntsville, USA), Dr David Quéré (Physique et Mécanique des Milieux Hétérogènes ESPCI, FRANCE), Dr Marcelo García (College of Engineering University of Illinois at Urbana-Champaign) and Dr Víctor Calo (Earth and Environmental Science and Engineering, King Abdullah University of Science and Technology (KAUST) and Institute for Computational Engineering and Sciences (ICES), University of Texas at Austin). In addition, we had 18 invited talks and more than fifty contributions that were presented in poster sessions. On behalf of both the Honorary Committee and the Local Committee, we would like to thank the Institutions that sponsored the Meeting, namely: the National Scientific Research Council of Argentina (CONICET) and the National Agency for Scientific and Technology Promotion (ANPCyT), who supported the meeting with grants-in-aid; and the Universidad Nacional del Litoral, who provided all the logistic support needed to achieve a successful and enjoyable Conference. All the papers constituting this volume of Journal of Physics: Conference Series have been reviewed by experts in the field; though they are just a limited number of the works presented at the Meeting the volume provides a scientific record of the topics discussed. We hope that the readers will enjoy the reading. Fernando Adolfo Saita and María Delia Giavedoni

Pick-Up Ion Instabilities at Planetary Magnetospheres  

NASA Technical Reports Server (NTRS)

This effort involved the analysis of low frequency waves as observed by the Galileo spacecraft near the Galilean moon, Io. Io is a significant source of material, especially SO2, and various products of dissociation, and further these atoms and molecules are readily ionized. The initial velocity of the ions is essentially that of the neutral species, i.e., the Keplerian velocity. The plasma, on the other hand is co-rotating, and there is a differential flow of the order 57 km/s between the plasma and the neutral particles. Thus pick-up ion instabilities are Rely to occur within the Jovian magnetosphere. Indeed, magnetometer observations from the Galileo spacecraft clearly show ion cyclotron waves that have been identified with a large variety of plasma species, such as O+, S++ (which has the same gyro-frequency as O+), S+, and SO2+. Typically, however, the dominant frequency is near the SO2+ gyro-frequency. The research effort was originally planned to be a team effort between Robert J. Strangeway as the Principal Investigator, and Debbie Huddleston, who was an Assistant Research Geophysicist at UCLA. Unfortunately, Dr. Huddleston took a position within Industry. The effort was therefore descoped, and Dr. Strangeway instead pursued a collaboration with Dr. Xochitl Blanco-Cano, of the Instituto de Geofisica, Universidad Nacional Autonoma de Mexico. This has proved to be a productive collaboration, with several papers and publications arising out of the effort. The magnetic field oscillations near lo generally fall into two types: ion cyclotron waves, with frequencies near an ion gyro-frequency, and lower frequency mirror-mode waves. The ion cyclotron waves are mainly transverse, and frequently propagate along the ambient magnetic field. The mirror-mode waves are compressional waves, and they have essentially zero frequency in the plasma rest frame. One of the purposes of our investigation is to understand what controls the types of wave modes that occur, since both wave modes can be drive unstable by the pressure anisotropy associated with the pick up ions. The pick ion velocity is perpendicular to the ambient magnetic field, and is generally much larger than the thermal velocity, at least initially. At its simplest, we found that the ion cyclotron waves are controlled by the parameters of the species in gyro-resonance with the wave. Thus, while the growth rates for the lower mass (higher gyro-frequency) pick-up ions are generally larger, we found that the heavier SO2+ ion cyclotron waves are generally preferred. This is because one of the effects of the wave instability is to diffuse the ions in pitch angle and energy. The lower mass ions therefore consist of both a ring of recently created pick-up ions, and a thermal background. This thermal background quenches the ion cyclotron instability. SO2+ is different, however. Being a molecule, the species can also dissociate. Our analysis suggests that the dissociation acts on a time scale comparable to or faster than the velocity space diffusion time scale. There are consequently no thermal SO2+ ions to quench the instability. We have also investigated the mirror-mode. This mode can at times grow more rapidly than the individual ion cyclotron waves. This is mainly because the mirror-mode can grow off the pressure anisotropy of the individual species with which the waves are in resonance. Lastly, as part of this effort we have begun to investigate the instability for obliquely propagating modes. Galileo observations show that at times the ion cyclotron waves are significantly elliptically polarized, and further the wave vector is at a large angle to the field, significant growth can occur for oblique propagation. Depending on the group velocity of the waves, it is possible that obliquely propagating modes have higher advective growth rate, but this has yet to be determined.

Use of Physio-Hydrological Units for SMOS Validation at the Valencia Anchor Station Study Area  

NASA Astrophysics Data System (ADS)

The SMOS space mission will soil moisture over the continents and ocean surface salinity with the sufficient resolution to be used in global climate change studies. With the aim of validating SMOS land data and products at the Valencia Anchor Station site (VAS) in a Mediterranean Ecosystem area of Spain, we have designed a sample methodology using a subdivision of the landscape in environmental units related to the spatial variability of soil moisture (Millán-Scheiding, 2006; Lopez-Baeza, et al. 2008). These physio-hydrological units are heterogeneously structured entities which present a certain degree of internal uniformity of hydrological parameters. The units are delimited by integrating areas with the same physio-morphology, soil type, vegetation, geology and topography (Flugel, et al 2003; Millán-Scheiding et al, 2007). Each of these units presented over the same pedological characteristics, vegetation cover, and landscape position should have a certain degree of internal uniformity in its hydrological parameters and therefore similar soil moisture (SM). The main assumption for each unit is that the dynamical variation of the hydrological parameters within one unit should be minimum compared to the dynamics of another unit. This methodology will hopefully provide an effective sampling design consisting of a reduced number of measuring points, sparsely distributed over the area, or alternatively, using SM validation networks where each sampling point is located where it is representative of the mean soil moisture of a complete unit area. The Experimental Plan for the SMOS Validation Rehearsal Campaign at the VAS area of April-May 2008 used this environmental subdivision in the selection and sampling of over 21.000 soil moisture points in a control area of 10 x 10 km2. The ground measurements were carried out during 4 nights corresponding to a drying out period of the soil. The sampling consisted of 700 plots with 4 volumetric SM cylinders and 7 Delta-T Theta Probe measurements (with 3 repetitions each), covering the whole area. This experimental campaign permits the characterization of the soil moisture distribution within each physio-hydrological unit and results in a soil moisture map of the VAS site. All of it used for the validation of the aircraft observations done throughout the campaign. The ground measurement results obtained indicate that soil properties and vegetation cover are the parameters of the physio-hydrological units that most influence the moisture of the soil. This relationship will permit a more simple delimitation of the physio-hydrological Units and a reduction of the number of sample points for the calibration/validation of SMOS products.

Usage and Effectiveness of a Fully Automated, Open-Access, Spanish Web-Based Smoking Cessation Program: Randomized Controlled Trial  

PubMed Central

Background The Internet is an optimal setting to provide massive access to tobacco treatments. To evaluate open-access Web-based smoking cessation programs in a real-world setting, adherence and retention data should be taken into account as much as abstinence rate. Objective The objective was to analyze the usage and effectiveness of a fully automated, open-access, Web-based smoking cessation program by comparing interactive versus noninteractive versions. Methods Participants were randomly assigned either to the interactive or noninteractive version of the program, both with identical content divided into 4 interdependent modules. At baseline, we collected demographic, psychological, and smoking characteristics of the smokers self-enrolled in the Web-based program of Universidad Nacional de Educación a Distancia (National Distance Education University; UNED) in Madrid, Spain. The following questionnaires were administered: the anxiety and depression subscales from the Symptom Checklist-90-Revised, the 4-item Perceived Stress Scale, and the Heaviness of Smoking Index. At 3 months, we analyzed dropout rates, module completion, user satisfaction, follow-up response rate, and self-assessed smoking abstinence. Results A total of 23,213 smokers were registered, 50.06% (11,620/23,213) women and 49.94% (11,593/23,213) men, with a mean age of 39.5 years (SD 10.3). Of these, 46.10% (10,701/23,213) were married and 34.43% (7992/23,213) were single, 46.03% (10,686/23,213) had university education, and 78.73% (18,275/23,213) were employed. Participants smoked an average of 19.4 cigarettes per day (SD 10.3). Of the 11,861 smokers randomly assigned to the interactive version, 2720 (22.93%) completed the first module, 1052 (8.87%) the second, 624 (5.26%) the third, and 355 (2.99%) the fourth. Completion data was not available for the noninteractive version (no way to record it automatically). The 3-month follow-up questionnaire was completed by 1085 of 23,213 enrolled smokers (4.67%). Among them, 406 (37.42%) self-reported not smoking. No difference between groups was found. Assuming missing respondents continued to smoke, the abstinence rate was 1.74% (406/23,213), in which 22,678 were missing respondents. Among follow-up respondents, completing the 4 modules of the intervention increased the chances of smoking cessation (OR 1.95, 95% CI 1.27-2.97, P<.001), as did smoking 30 minutes (OR 1.58, 95% CI 1.04-2.39, P=.003) or 1 hour after waking (OR 1.93, 95% CI 1.27-2.93, P<.001) compared to smoking within the first 5 minutes after waking. Conclusions The findings suggest that the UNED Web-based smoking cessation program was very accessible, but a high level of attrition was confirmed. This could be related to the ease of enrollment, its free character, and the absence of direct contact with professionals. It is concluded that, in practice, the greater the accessibility to the program, the lower the adherence and retention. Professional support from health services and the payment of a reimbursable fee could prevent high rates of attrition.



The Red de Monitoreo de BosquesAndinos: A communication platform for science and policy in the Andean countries  

NASA Astrophysics Data System (ADS)

A workshop held in October 2012 in Lima, Peru, brought together more than 40 scientists and policy makers working in Andean forest ecosystems, one of the richer and most threatened ecosystems of the world. Among the various results of the workshop, there is the formation of the network "Red de Bosques Andinos". The goals of the network include to stimulate scientific research in Andean forest ecosystems by promoting collaboration among scientists, and to serve as a platform to facilitate applied research and communication between scientists and policy makers. Current members of the network include scientists of Argentina, Colombia, Ecuador, Germany, Peru, USA, and representatives of Ministries of Environment and the National Climate Change Adaptation Programs of Colombia, Bolivia, Ecuador, and Peru. The network has started to work in two critical documents for the region. The first one is an extended protocol to monitor diversity and carbon in Andean forests. This protocol, partly based on unpublished efforts, has been developed by the Instituto de Ecología Regional, Universidad de Tucuman, Argentina, and has been revised and improved by experts working in the Andes. The document describe methods to document ecological changes that take place over mid- and long periods of time. It focuses on monitoring changes on the diversity and growth of trees, shrubs and lianas, cover of herbaceous species, and carbon content in forests. This extended protocol will be a useful tool for students and researchers interested in conducting long-term ecological research. Moreover, the use of this tool will produce standardized data needed to understand ecological processes that take place at large spatial scales. The document will be freely available at The second document consists of an analysis of the dynamics of trees and carbon in the Andean region. The members of the network have contributed with data of more than 70 permanent forest plots located from Colombia to Argentina, some of them monitored since 1990. The initial results indicate that warmer, wetter, and more seasonal forests had higher rates of turnover of individuals, and biomass. Most of these patterns held for both, tropical and subtropical forest plots. The study will be completed in 2013, and will be the first study of forest dynamics and carbon content for the countries in the region. Finally, it is the aim of the Andean Forest Network to bring together scientists and policy-makers interested in research, management and conservation of the Andean forest. The creation of the network and the development of its first two products have been possible thanks to the financial support of the Swiss Agency of International Cooperation (COSUDE) through the CIMA project, the Dutch Technical Agency (GIZ), and the endorsement of the Secretaría General de Naciones (SG-CAN). The coordination of the network is currently held by Selene Báez, at CONDESAN ( Please contact us if you need more information or if you are interested in becoming part of the network.

[Interventional study in the natural evolution of Chagas disease. Evaluation of specific antiparasitic treatment. Retrospective-prospective study of antiparasitic therapy].  


In this study is presented the comparative therapeutical experience comparing the Allopurinol, Benznidazol y Nifurtimox, in a prospective following in a long term, considering the responses to the parasitemia, specific serology and evolution of the clinic manifestations and complementaries in the 535 chronic chagasic cases (44.5%), instead of 668 patients who did not get any treatment (1203 chagasic cases followed for more than 5 years average). This study was done between April 1984 and April 1994 in patients with and without cardiopathy, in the Córdoba Hospital and the Salud Estudiantil Direccion, Universidad Nacional de Córdoba (U.N.C.); from them, 309 patients were given Allopurinol, 130 were given Benznidazol, and 96 were given Nifurtimox, with usual doses of Benznidazol and Nifurtimox, but with Allopurinol it was made an study evaluating the answering-doses, with a following time of post-therapeutic average of 55.6 months (D.S. = + -57 m.) The comparative parameters were the starting clinic characteristics, the qualitative and quantitative for Chagas, the pre-treatment xerodiagnostic, the treatment fulfillment, the treatment duration, the adverse effects, the treatment abandon, the time of postreatment longitudinal following till the last clinic-complementary evaluation, the clinic characteristics at the end of the following period; quantitative and qualitative serology for Chagas after the treatment, and post-treatment xerodiagnostic. It was observe a prevalence of Electrocardiographic Changes in the ECG in rest, in the first complementary evaluation in 76 of the 535 "Treated" and in the 225 "No-treated" patients, being Electrocardiographic abnormality proportion much more in the "No-treated" patients (P = 0.000000). After the end of the following period it was thought to have been found Miocardic Damage Progression in 120 patients "No-treated" and in 31 "Treated" patients (17.9% and 5.8% respectively) (P = 0.0000000). The complications in the evolution course were proved in 113 of the "No-treated" and in 19 of the "Treated" patients (16.9% and 3.5%, being this a statistically significant difference (P = 0.0000000). The mortality along the evolution was proved in 37 of the "No-Treated:" patients and in 7 of the "Treated" patients (5.5% and 1.3%), being this a statistically significant difference (P = 0.00019). The most tolerated drug and the one with the least incidence of therapeutic abandons was the Allopurinol. The xerodiagnostic negativization percentages were 72.5% for Allopurinol, 76.4% for Benznidazol and 76.5% for Nifurtimox (non-significant differences). A year and two years after the end of the treatment was made a titled serology with the Inmunofluorescence and Indirect Hemoaglutination Tests, getting significant statistical differences between the three drugs, resulting lower the values obtain after the treatment with Benznidazol and Nifurtimox than with Allopurinol (P = 0.0042 and P = 0.00039), respectively). The biggest proportion of Progression in the Cardiopathies, Complications, General Mortality and Attributed Mortality in "No Treated" (specially in older than 30 years) significant both for infected patient and slight cardiopathy, stabilises the possibility of stopping or reducing the morbid course of the Chronic Chagasic Cardiopathy, specially relevant in the formers, where the pathogenic process seems to be accelerated related to the latters. The negativation of the parasitemia and the parasitemia and the title disminution of the specific serology like effectiveness treatment parameters, and the stopping in the progression or dissemination of the incidence in new cases of Chronic Chagasic Cardiopathies were considered to be the real benefit of the antiparasitaric therapeutic in the Chagas Disease. As a conclusion, it is thought that the further the instauration of the specific antiparasitaric treatment the more the possibilities of effectiveness, as well as the increase in the probabilities of

Variations of the Geomagnetic Field During the Holocene-Pleistocene: Relative Paleointensity Records From South-Western Argentina  

NASA Astrophysics Data System (ADS)

I present a review of the research carried out by the Group of Geomagnetism at Universidad Nacional del Centro (Argentina) on paleointensity records from bottom sediments from three lakes: Escondido (Gogorza et al., 2004), Moreno (Gogorza et al., 2006) and El Trébol (Gogorza et al., 2007; Irurzun et al., 2008) (South-Western Argentina, 41° S, 71° 30'W). Based on these studies, we construct a first relative (RPI) stack for South-Western Argentina covering the last 21,000 14C years BP. The degree of down-core homogeneity of magnetic mineral content as well as magnetic mineral concentration and grain sizes vary between all lakes and are quantified by high-resolution rock magnetic measurements. Rock magnetic studies suggest that the main carriers of magnetization are ferrimagnetic minerals, predominantly pseudo-single domain magnetite The remanent magnetization at 20 mT (NRM20mT) was normalized using the anhysteric remanent magnetization at 20mT (ARM20mT), the saturation of the isothermal remanent at 20 mT (SIRM20mT) and the low field magnetic susceptibility {k}. Coherence function analysis indicates that the normalised records are free of environmental influences. Our paleointensity (NRM20mT/ ARM20mT) versus age curve shows a good agreement with published records from other parts of the world suggesting that, in suitable sediments, paleointensity of the geomagnetic field can give a globally coherent, dominantly dipolar signal.

Accelerations from the September 5, 2012 (Mw=7.6) Nicoya, Costa Rica Earthquake  

NASA Astrophysics Data System (ADS)

Since 1984, the Seismic Network of the Volcanological and Seismological Observatory of Costa Rica, Universidad Nacional (OVSICORI-UNA) has been recording and registering the seismicity in Costa Rica. Before September 2012, the earthquakes registered by this seismic network in northwestern Costa Rica were moderate to small, except the Cóbano earthquake of March 25, 1990, 13:23, Mw 7.3, lat. 9.648, long. 84.913, depth 20 km; a subduction quake at the entrance of the Gulf of Nicoya and generated peak intensities in the range of MM = VIII near the epicentral area and VI-VII in the Central Valley of Costa Rica. Six years before the installation of the seismic network, OVSICORI-UNA registered two subduction earthquakes in northwestern Costa Rica, specifically on August 23, 1978, at 00:38:32 and 00:50:29 with magnitudes Mw 7.0 (HRVD), Ms 7.0 (ISC) and depths of 58 and 69 km, respectively (EHB Bulletin). On September 5, 2012, at 14:42:02.8 UTC, the seismic network OVSICORI-UNA registered another large subduction earthquake in Nicoya peninsula, northwestern Costa Rica, located 29 km south of Samara, with a depth of 21 km and magnitude Mw 7.6, lat. 9.6392, long. 85.6167. This earthquake was caused by the subduction of the Cocos plate under the Caribbean plate in northwestern Costa Rica. This earthquake was felt throughout the country and also in much of Nicaragua. The instrumental intensity map for the Nicoya earthquake indicates that the earthquake was felt with an intensity of VII-VIII in the Puntarenas and Nicoya Peninsulas, in an area between Liberia, Cañas, Puntarenas, Cabo Blanco, Carrillo, Garza, Sardinal, and Tamarindo in Guanacaste; Nicoya city being the place where the maximum reported intensity of VIII is most notable. An intensity of VIII indicates that damage estimates are moderate to severe, and intensity VII indicates that damage estimates are moderate. According to the National Emergency Commission of Costa Rica, 371 affected communities were reported; most reports were of damage to homes, bridges, roads, aqueducts, schools and public buildings. There were 12 structures reported with damages in hospitals and health care sites, specifically in Hojancha, Nandayure, Nicoya, Santa Cruz and Puntarenas. There are no reports of deaths from the earthquake and only 78 injured and a total of 1474 people mobilized, which includes hospital evacuations and preventive transfers. 223 schools were reported with various damages, mostly in Santa Cruz, Nicoya, Carrillo, Nandayure, and Puntarenas. A total of 98 homes were reported with severe damage, 805 with moderate damage and 87 with minor damage. In general, the buildings in the Nicoya Peninsula (where the highest intensities were reported) endured the Nicoya Earthquake. Also, acceleration data from OVSICORI, UCR, LIS-UCR, and the Seismic Strong Motion Array Project (SSMAP) show a range of accelerations (500 - 10 cm/sec2) for distance range of 30-250 km, respectively.

Decision Theories used in Areas Planning around La Colacha Basin (Cordoba, Argentina) considering Natural and Human Hazards  

NASA Astrophysics Data System (ADS)

The authors of U.P.M. have had relations with Argentine Universities and Administrations, in part with J.M.Cisneros that is Professor at Universidad Nacional de Rio Cuarto in Prov. de Córdoba Arg., and have applied Decision Theories with Mathematic tools for the planning of defences and uses of soils in these areas and especially of La Colacha bassin enlarged with larger areas around it as "Cuenca de los Arroyos Menores" at West and South of Rio Cuarto. These large flat lands have loess soils brought by winds from Los Andes that are much far at West, there is a very old line of not high mountains at West near the study area from which rivers flow with little slopes to somehow lower flat areas at West with some marshes. Rivers through loess get regressive erosions with rains forming kilometres long ditches in the loess called "cárcavas" some meters deep and quite large across otherwise flat agricultural lands, and J.M. Cisneros, that has numerous publications about local soil uses, has directed diverse genie rural works to halt the regression of some of them. Part of the study is about protection against floods and "cárcavas". There are famous experiences and records of higher inundations of large areas by rivers. Latitude of Rio Cuarto is 31°25' South, that area is temperate refreshed by south winds, Zonda föhn winds from West being hotter and drier, and there are monsoons and so winter in July is dry and summer and December has rains, that average 829mm per year. Wind erosion and fires occur frequently on these loess soils in winter. This is an excellent area for agriculture but some actual uses may be not sustainable in long term such as excesses with genetically engineered soy, and the authors have studied aided with mathematical models (ELECTRE I, PROMETHEE and Expert Choice) the preferences of various alternative systems of land use (Autochthonous forest, High value forest, Traditional farms, Erosion control Crop with agriculture use, and Erosion control Crop with industrial use (biomass) ) in view of diverse Criteria (Water erosion index, Eolian erosion index, Implementation facility, Water resources, Economical Benefits, Hand power, Environmental Impacts, social Acceptance), as contribution for territorial planning, in part in relation with local official agencies. There are numerous references in local Spanish Argentine literature about the region uses of soils, some of J.M.Cisneros, and many general references, let note about Decision Theory: (1) Grau, J.

SIRGAS: ITRF densification in Latin America and the Caribbean  

NASA Astrophysics Data System (ADS)

The continental reference frame of SIRGAS (Sistema de Referencia Geocéntrico para las Américas) is at present realized by the SIRGAS Continuously Operating Network (SIRGAS-CON) composed by about 200 stations distributed over all Latin America and the Caribbean. SIRGAS member countries are qualifying their national reference frames by installing continuously operating GNSS stations, which have to be consistently integrated into the continental network. As the number of these stations is rapidly increasing, the processing strategy of the SIRGAS-CON network was redefined during the SIRGAS 2008 General Meeting in May 2008. The new strategy relies upon the definition of two hierarchy levels: a) A core network (SIRGAS-CON-C) with homogeneous continental coverage and stabile site locations ensures the long-term stability of the reference frame and provides the primary link to the ITRS. Stations belonging to this network have been selected so that each country contributes with a number of stations defined according to its surface and guarantying that the selected stations are the best in operability, continuity, reliability, and geographical coverage. b) Several densification sub-networks (SIRGAS-CON-D) improve the accessibility to the reference frame. The SIRGAS-CON-D sub-networks shall correspond to the national reference frames, i.e., as an optimum there shall be as many sub-networks as countries in the region. The goal is that each country processes its own continuously stations following the SIRGAS processing guidelines, which are defined in accordance with the IERS and IGS standards and conventions. Since at present not all of the countries are operating a processing centre, the existing stations are classified in three densification networks (a Northern, a middle, and a Southern one), which are processed by three local processing centres until new ones are installed. As SIRGAS is defined as a densification of the ITRS, stations included in the core network, as well as in the densification sub-networks match the requirements, characteristics, and processing performance of the ITRF. The SIRGAS-CON-C network is processed by DGFI (Deutsches Geodätisches Forschungsinstitut, Germany) as the IGS-RNAAC-SIR. The Local Processing Centres are for the Northern sub-network IGAC (Instituto Geográfico Augustín Codazzi, Colombia), for the middle sub-network IBGE (Instituto Brasileiro de Geografia e Estátistica, Brazil), and for the Southern sub-network IGG-CIMA (Instituto de Geodesia y Geodinámica, Universidad Nacional de Cuyo, Argentina). These four Processing Centres deliver loosely constrained weekly solutions for station coordinates (i.e., satellite orbits, satellite clock offsets, and Earth orientation parameters are fixed to the final weekly IGS solutions and coordinates for all sites are constrained to ?1 m). The individual contributions are integrated in a unified solution by the SIRGAS Combination Centres (DGFI and IBGE) according to the following strategy: 1) Individual solutions are reviewed/corrected for possible format problems, data inconsistencies, etc. 2) Constraints imposed in the delivered normal equations are removed. 3) Sub-networks are individually aligned to the IGS05 reference frame by applying the No Net Rotation (NNR) and No Net Translation (NNT) conditions. 4) Coordinates obtained in (3) for each sub-network are compared to IGS05 values and to each other in order to identify possible outliers. 5) Stations with large residuals (more than 10 mm in the N-E component, and more than 20 mm in the Up component) are reduced from the normal equations. Steps (3), (4), and (5) are done iteratively. 6) Since at present the four Analysis Centres are processing GPS observations only and all of them use the Bernese Software for computing weekly solutions, relative weighting factors are not applied in the combination. 7) Individual normal equations are accumulated and solved for computing a loosely constrained weekly solution for station coordinates (i.e., coordinates for all stations are constrained to 1 m).

EDITORIAL: Squeezed states and uncertainty relations  

NASA Astrophysics Data System (ADS)

This special issue of Journal of Optics B: Quantum and Semiclassical Optics is composed mainly of extended versions of talks and papers presented at the Eighth International Conference on Squeezed States and Uncertainty Relations held in Puebla, Mexico on 9-13 June 2003. The Conference was hosted by Instituto de Astrofísica, Óptica y Electrónica, and the Universidad Nacional Autónoma de México. This series of meetings began at the University of Maryland, College Park, USA, in March 1991. The second and third workshops were organized by the Lebedev Physical Institute in Moscow, Russia, in 1992 and by the University of Maryland Baltimore County, USA, in 1993, respectively. Afterwards, it was decided that the workshop series should be held every two years. Thus the fourth meeting took place at the University of Shanxi in China and was supported by the International Union of Pure and Applied Physics (IUPAP). The next three meetings in 1997, 1999 and 2001 were held in Lake Balatonfüred, Hungary, in Naples, Italy, and in Boston, USA, respectively. All of them were sponsored by IUPAP. The ninth workshop will take place in Besançon, France, in 2005. The conference has now become one of the major international meetings on quantum optics and the foundations of quantum mechanics, where most of the active research groups throughout the world present their new results. Accordingly this conference has been able to align itself to the current trend in quantum optics and quantum mechanics. The Puebla meeting covered most extensively the following areas: quantum measurements, quantum computing and information theory, trapped atoms and degenerate gases, and the generation and characterization of quantum states of light. The meeting also covered squeeze-like transformations in areas other than quantum optics, such as atomic physics, nuclear physics, statistical physics and relativity, as well as optical devices. There were many new participants at this meeting, particularly from Latin American countries including, of course, Mexico. There were many talks on the subjects traditionally covered in this conference series, including quantum fluctuations, different forms of squeezing, unlike kinds of nonclassical states of light, and distinct representations of the quantum superposition principle, such as even and odd coherent states. The entanglement phenomenon, frequently in the form of the EPR paradox, is responsible for the main advantages of quantum engineering compared with classical methods. Even though entanglement has been known since the early days of quantum mechanics, its properties, such as the most appropriate entanglement measures, are still under current investigation. The phenomena of dissipations and decoherence of the initial pure states are very important because the fast decoherence can destroy all the advantages of quantum processes in teleportation, quantum computing and image processing. Due to this, methods of controlling the decoherence, such as by the use of different kinds of nonlinearities and deformations, are also under study. From the very beginning of quantum mechanics, the uncertainty relations were basic inequalities distinguishing the classical and quantum worlds. Among the theoretical methods for quantum optics and quantum mechanics, this conference covered phase space and group representations, such as the Wigner and probability distribution functions, which provide an alternative approach to the Schr\\"odinger or Heisenberg picture. Different forms of probability representations of quantum states are important tools to be applied in studying various quantum phenomena, such as quantum interference, decoherence and quantum tomography. They have been established also as a very useful tool in all branches of classical optics. From the mathematical point of view, it is well known that the coherent and squeezed states are representations of the Lorentz group. It was noted throughout the conference that another form of the Lorentz group, namely, the 2 x 2 representation of the SL(2,c) group, is becoming

PREFACE: Spanish Relativity Meeting/ERE2009Gravitation in the Large  

NASA Astrophysics Data System (ADS)

Scientists working in Relativity, Gravitation and Cosmology in Spanish institutions have been organising the Spanish Relativity Meetings (ERE) for more than 30 years now, and 2009 was the turn of the group at the University of the Basque Country (UPV/EHU) to continue this well established tradition. There is no doubt these meetings have become a benchmark in the field not only because of the high scientific level reached in each edition, but also because of the almost legendary relaxed atmosphere. The support of our sponsors --Spanish Ministry of Science and Innovation, through the funding actions FIS2008-03716-E and FIS2008-04494-E, Basque Government, UPV/EHU, and Spanish Relativity and Gravitation Society (SEGRE)-- and specially the scientific and social contributions of all the participants turned the ERE2009 a memorable edition for us, and we hope this is also the impression of everyone else involved in this meeting. The organising committee was very pleased to present an excellent panel of invited speakers to dissert on four topics that are gathering enormous interest and activity: Quantum and thermodynamical effects in Gravity, Modern Cosmology, Numerical Relativity and Black holes. But the meeting also boasted a high scientific level thanks to the more than a hundred other participants from many different countries whose enthusiasm was an excellent proof of the good health of Relativity, Gravitation and Cosmology as a research area. The scientific programme started on the 7th, with an opening by a representative of the Principal of the University of the Basque Country, along with the Deputy Mayor of Bilbao, and the Chair of the conference, José M.M. Senovilla. Lectures were delivered on the 7th, 8th, 9th and 11th of September 2009 following a scheme of plenary sessions in the morning (the first lecture always being an invited one) and two parallel sessions in the afternoon. There were of course coffee-breaks to refresh bodies and spirits and encourage the interaction between the participants and promote collaborative links, as scientific interaction is one of the main purposes of the meeting. The 10th was devoted to an emotional homage to Prof. Jesús Martín, with special talks to honour his scientific and academic careers. And last but not least, there was a quite plenty programme of social events, as has become customary in the ERE meetings; the programme started on the 6th with a friendly reception at the ''Ein Prosit'' bar, on the 7th we had a reception at the ''Salón Árabe'' of the Bilbao Town Hall hosted by the Deputy Mayor, the SEGRE public lecture in the Main Library of Bilbao on the 8th, a guided visit to the ''Ría de Bilbao'' on the Txinbito boat, and a closing dinner at the Aspaldiko restaurant in Loiu. As editors of these proceedings and members of the Organizing Committee we want to take advantage of this opportunity to thank warmly everyone who made this conference possible and make the wish that in future editions to be held in Bilbao we will have again such a splendid support from the institutions and the scientific community.

Efectos difusivos en la formación de enanas blancas de Helio de baja masa en sistemas binarios cerrados  

NASA Astrophysics Data System (ADS)

In the last years, and thanks to advances in observational techniques, many astronomers have discovered in a great number of binary radio-pulsars the presence of a helium white dwarf resulting from a previous evolutionary state in which the progenitor of this star experienced one or more episodes of mass transfer to the compact component in the pair. That is the case for PSR B1855+09 (van Kerkwijk, M. H., Bell, J. F, Kaspi, V. M., & Kulkarni, S. R. 2000, ApJ 530, L37), where the mass for the white dwarf is known accurately from measurements of the Shapiro delay of the pulsar signal, MWD = 0.258+0.028-0.016 M?; for PSR J02018 + 4232 (Bassa, C. G., van Kerkwijk, M. H., & Kulkarni, S. R. 2003, A&A, 403, 1067), the spectra confirm that the companion is a helium-core white dwarf of ? 0.2 M?. On the other hand, there are several authors (Ferraro, F., Possenti, A., Sabbi, E., & D'Amico, N. 2003, ApJ, 596, L211; Bassa et al. 2003) that have identified the optical binary companion to the BMSP PSR J1911 - 5958A, located in the halo of the Galactic globular cluster NGC 6752, like a blue star whose position in the color-magnitude diagram is consistent with the cooling sequence of a low-mass, ? 0.17 - 0.20 M?, low metallicity helium white dwarf at the cluster distance. Finally, the color and magnitude of the stellar companion for B 1620-26 indicate that is a white dwarf of 0.34 ± 0.04 M? (Sigurdson, S., Richer, H. B., Hansen, B. M., Stairs, I. H. & Thorset, S. E. 2003, Science, 301, 193S). This has motivated us to study the formation of low mass helium white dwarfs in the context of binary evolution. For that purpose, using the code of binary evolution, entirely developed in the Facultad de Ciencias Astronómicas y Geofísicas of the Universidad Nacional de La Plata, Argentina, we have investigated the effects of diffusive processes on the evolution of a star member of a close binary system. A similar study was performed for Althaus, L. G., Serenelli, A. M., & Benvenuto, O. G. (2001, MNRAS, 323, 471) but in that paper the mass transfer was mimicked by subtracting mass to a progenitor of 1 M? to obtain the mass for the desired object. Actually, our binary code has a full nuclear reactions network for hydrogen and helium burning that allowed us to follow the abundances of fifteen isotopes throughout the entire evolution of the star. We have also included a detailed equation of state. The mass loss treatment is non conservative. We have modified the conditions for the beginning and end of mass transfer episodes. In our previous version, we assumed it to occur when the stellar radius was greater or smaller, respectively, that the Roche Lobe radius for the star. This introduced numerical problems, especially at the end of mass transfer phases. We adopted H. Ritter (1988, A&A, 202, 93) formulation that considers a finite scale height in the stellar atmosphere. The numerical behaviour in much more satisfactory, besides that it constitutes a more appropriate description for the physical problem. We perform the calculations for the evolution of the primary star in a close binary system of initial mass 2 M?, initial period of 1 day, initial mass ratio of 1.4142 and solar metallicity. We have done the calculations in four cases: A) with diffusion and all Roche Lobe overflows, B) with diffusion and only the first Roche Lobe overflow, C) without diffusion and all Roche Lobe overflows, D) without diffusion and only the first Roche Lobe overflow. Cases B) and D) where performed to compare with results obtained for Althaus et al. (2001). The main conclusion of this work is that the age of these objects is mainly determined by diffusive effects, and the late stages of mass transfer, not considered in Althaus et al. (2001), constituted a minor effect on the scales of cooling times.

Recent SO2 camera and OP-FTIR field measurements in Mexico and Guatemala  

NASA Astrophysics Data System (ADS)

Between 22 and 30 November 2012 a field campaign was carried out at Mexico and Guatemala with the objectives of state the volcanic gas composition and flux fingerprints of Popocatepetl, Santiaguito, Fuego and Pacaya by exploiting simultaneously UV-camera and FTIR measurements. Gases were measured remotely using instruments sensitive to ultraviolet and infrared radiation (UV spectrometer, SO2-camera and OP-FTIR). Data collection depended on the requirements of the methodology, weather condition and eruptive stage of the volcanoes. OP-FTIR measurements were carried out using the MIDAC interferometer with 0.5 cm-1 resolution. Spectra were collected in solar occultation mode in which the Sun acts as an infrared source and the volcanic plume is interposed between the Sun and the spectrometer. At Santiaguito spectra were also collected in passive mode using the lava flow as a radiation source. The SO2-camera used for this study was a dual camera system consisting of two QS Imaging 640s cameras. Each of the two cameras was outfitted with two quartz 25mm lens, coupled with two band-pass filters centred at 310nm and at 330nm. The imaging system was managed by a custom-made software developed in LabView. The UV-camera system was coupled with a USB2000+ spectrometer connected to a QP1000-2-SR 1000 micron optical fiber with a 74-UV collimating lens. For calibration of plume imagery, images of five quartz cells containing known concentration path-lengths of SO2 were taken at the end of each sampling. Between 22 and 23 November 2012 UV-camera and FTIR observations were carried out at Popocatepetl. During the time of our observation, the volcano was characterised by pulsing degassing from the summit crater forming a whitish plume that dispersed rapidly in the atmosphere according to wind direction and speed. Data were collected from the Observatorio Atmosférico Altzomoni (Universidad Nacional Autónoma de México) at 4000 metre a.s.l. and at a distance of ~12 km from the volcano summit. SO2 camera observations were made for ~30 and 130 minutes on the 22 and 23 November, respectively, with a sampling rate of ~7 seconds. FTIR measurements were carried out for 20 and 15 minutes on 22 and 23 November. At Santiaguito volcano, we carried out volcanic gas measurements on 27 and 28 November 2012. During the period of our observations the volcano activity was characterised by lava flow extrusion on the S flank of dome edifice. Occasionally, incandescent blocks detached from the lava flow front rolling onto the dome flanks. During the time of our survey the explosive activity was low frequency (every ~5 - 6 hours). We observed a persistent and sustained degassing plume was observed occasionally polluted by ash. However, on 28 November at 5:25 local time, a violent pyroclastic flow occurred generating an ash-plume that rose ~5 km passing Santa Maria's summit and spreading ~30 km south. SO2 camera and FTIR data were simultaneously collected on 27 November from El Mirador at a distance of ~2 Km from the lava-dome. Data were collected for ~75 and ~90 minutes for SO2-camera and FTIR, respectively. On 28 November, due to the pyroclastic flow event, only distal solar occultation FTIR measurements and open-path UV spectra (using a USB spectrometer) were collected from the west flank of Santa Maria volcano. Both UV and IR spectra were recorded for ~60 minutes Ash released by the pyroclastic flow was sampled from a distance of 6.5 km from the volcano collecting the fallout products along a 60 minute time interval Data from the volcanic plumes of Pacaya and Fuego were collected on 29 and 30 November 2012. During our survey the eruptive activity of Pacaya consisted of weak puffing from the summit crater, while Fuego showed a weak outgassing occasionally interrupted by explosion from its summit crater. In both days, we carried out only SO2 camera measurements due to the poor weather conditions which prevented solar FTIR measurments. At both volcanoes, UV images were taken for a period of ~45 minutes from a distance of ~ 3 km and ~ 10 km, respectively. In th

Symbolic algorithms for the computation of Moshinsky brackets and nuclear matrix elements  

NASA Astrophysics Data System (ADS)

To facilitate the use of the extended nuclear shell model (NSM), a FERMI module for calculating some of its basic quantities in the framework of MAPLE is provided. The Moshinsky brackets, the matrix elements for several central and non-central interactions between nuclear two-particle states as well as their expansion in terms of Talmi integrals are easily given within a symbolic formulation. All of these quantities are available for interactive work. Program summaryTitle of program:Fermi Catalogue identifier:ADVO Program summary URL: Program obtainable from: CPC Program Library, Queen's University of Belfast, N. Ireland Licensing provisions:None Computer for which the program is designed and others on which is has been tested:All computers with a licence for the computer algebra package MAPLE [Maple is a registered trademark of Waterloo Maple Inc., produced by MapleSoft division of Waterloo Maple Inc.] Instalations:GSI-Darmstadt; University of Kassel (Germany) Operating systems or monitors under which the program has beentested: WindowsXP, Linux 2.4 Programming language used:MAPLE 8 and 9.5 from MapleSoft division of Waterloo Maple Inc. Memory required to execute with typical data:30 MB No. of lines in distributed program including test data etc.:5742 No. of bytes in distributed program including test data etc.:288 939 Distribution program:tar.gz Nature of the physical problem:In order to perform calculations within the nuclear shell model (NSM), a quick and reliable access to the nuclear matrix elements is required. These matrix elements, which arise from various types of forces among the nucleons, can be calculated using Moshinsky's transformation brackets between relative and center-of-mass coordinates [T.A. Brody, M. Moshinsky, Tables of Transformation Brackets, Monografias del Instituto de Fisica, Universidad Nacional Autonoma de Mexico, 1960] and by the proper use of the nuclear states in different coupling notations. Method of solution:Moshinsky's transformation brackets as well as two-nucleon matrix elements are provided within the framework of MAPLE. The transformation brackets are evaluated recursively for a given number of shells and utilized for the computation of the two-particle matrix elements for different coupling schemes and interactions. Moreover, a simple notation has been introduced to handle the two-particle nuclear states in ll-, LSJ-, and jj-coupling, both in the center-of-well and the relative and center-of-mass coordinates. Restrictions onto the complexity of the problem:The program supports in principle an arbitrary number of shell states with the only limitation given by the computer resources themselves. Typically, the time requirements for the recursive computation of the Moshinsky brackets and matrix elements increase rapidly with the number of the allowed shell states but can be reduced significantly by the pre-calculation of the transformation brackets. Unusual features of the program:Moshinsky brackets are computed and provided in either numeric, algebraic or some symbolic form. In addition, the two-particle matrix elements are calculated for a scalar potential, spin-orbit coupling and tensorial forces, both in floating-point and algebraic notation. All two-particle matrix elements are expressed in terms of the Talmi integrals but can be evaluated also explicitly for several predefined types of the interaction. To simplify the handling of the program, a short but very powerful notation has been introduced which help the user to deal with the two-particle states in various coupling notations. The main commands of the current version of the program are described in detail in Appendix B. Typical running time:The computation of all Moshinsky brackets in floating-point notation, up to ?=6, takes about 5 s at a 2.26 GHz Intel Pentium IIII processor with 512 MB; in algebraic form, the same computations take about 13 s. Similarly, the computation of these brackets up to ?=10 requires in numeric and algebraic form about 5 and 15 min, respectively. Once the
