    2012-06-01

    This work analyzes the trajectory of the history course at the Faculdade Nacional de Filosofia of the Universidade do Brasil between 1939 and 1964/1965. Special emphasis is placed on the period between 1955 and 1965, when there was the separation of the history and geography courses, through to the onset of the reorganization of the schools and institutes of the university. The Faculdade Nacional de Filosofia was a benchmark for the other schools of philosophy in the country, as well as being a reference in the development of the history of education in Brazil. The approach adopted is geared to the field of the history of the historiography, with a focus on the study of the trajectories, institutions and relationship networks.

    PubMed

    Arakaki, Jorge

    2013-08-01

    This work looks into the meanings of nursing from the point of view of the students in an undergraduate nursing degree program. The research took place at the Universidad Nacional de Lanús using semistructured interviews - eleven individual and seven group interviews - carried out between 2008 and 2010. A content analysis was then undertaken and the most relevant meanings in relation to four themes were selected: reasons for studying nursing, what nursing is, nursing as a profession, and working in nursing. Multiple and diverse ways of defining nursing were uncovered. Utilizing some conceptual developments from the sociology of the professions, the meanings were organized into four conceptualizations that represent ways of understanding nursing: as a vocation, as a profession, with a utilitarian perspective and with a community perspective. The conclusions reached indicate the need to broaden the debate regarding the types of nurses that are being trained.

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

    NASA Astrophysics Data System (ADS)

    Orlov, V.

    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 λ/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.

  13. Teaching Global Change to Undergraduates at Universidad Nacional de Colombia for 15 years

    NASA Astrophysics Data System (ADS)

    Mesa, O. J.

    2015-12-01

    First let's describe the context. Approximately 80% of our students in Medellin major in engineering. In the National University system students can choose freely twenty percent of the credits. Their decisions are made taking into account various reasons. As far as we know the amount of work and the expected grades are factors besides the interest in the topics. Statistics show that there is an even distribution among complementary professional, cross-disciplinary and general interest courses. Plan B took the name from Lexter Brown book, which was the original inspiration and text. The program expanded with more in depth consideration to a general understanding of climate and climate change science, and to water and energy crises because they are close to my research area. But we consider other global change uses as well, including recycling, loss of biodiversity, food crises, economics of climate change and demographic and social issues. We developed a textbook whose title would translate as "Where is the Globe heading?" that refers to a usual saying during Christmas time in relation to candle balloons popular at that time of the year that children and teen-agers try to catch. The expression reflects the need for predictions, call for action, but also acknowledges that chance is a factor to consider. I believe it summarizes well the content of the course. The class meets in a large auditorium with 250 sits. We moved from the usual size room of about 50 because of the large demand during registration. This forced us to adjust the methodology, but our evaluation is that such a large audience is worthwhile. Student's feedbacks at the end of the semester confirm this with very good rating and general comments. Besides crude diagnostics of the problems based on data and science we always make an effort to present solutions. For instance there is ample consideration to renewal energy technologies. Globalization is also a theme of the course, there are local actions but in particular curbing of greenhouse gas emissions needs global actions. We need that this kind of efforts spread to many campuses around the world and need to share experiences to take advantage of globalization.

    Since 1983, the Engineering Institute at the Universidad Autonoma de Baja California (UABC) has offered a Geothermal Diploma Program. Sixty three students coming from different disciplines, have successfully completed the Program . This Program was offered by the UABC in collaboration with the Instituto de Investigaciones Electricas (IIE) and the Consejo Nacional de Ciencia y Tecnologia. A year later (1984), the Comision Federal de Electricidad joined in strengthening the program. Many trainees were sponsored by IIE and CONACYT. Since 1993, the program is not supported by them. They now only support Master and Ph.D. programs. This paper presents a review of the geothermal program from 1983 to 1994.

    We have analysed the meals for lunch and dinner at the University cafeteria, during one Winter week (June through September); in this season the menus are repeated every week round. A percentage analysis (humidity, ashes, lipids, protein, raw fiber, and nitrogen-free extract) was carried out on the sample, which were appropriately processed, thus allowing us to know the nutrients amount and caloric value of each meal. When examining both the formulas ingredients and the technique applied to the preparation of the meals, it was found that they have the best cooking quality, and also that their amount is sufficient (see tables). As to the meals nutrients, the results allow us to conclude that the diets are hypercaloric as well as hypoproteic, with a preponderance of proteins of animal origin.

    The Atlantic Forest is considered one of the world's biological diversity hotspots, and is increasingly threatened by the rapid destruction and fragmentation of its natural areas. The caddisflies (Trichoptera) of Itatiaia massif, an Atlantic Forest highland area, are inventoried and cataloged here. The catalog is based on examination of bibliographies, field work on many localities of Itatiaia massif (including Parque Nacional do Itatiaia — PNI), and the entomological collection Professor José Alfredo Pinheiro Dutra (DZRJ), Universidade Federal do Rio de Janeiro. A total of 92 species are recorded, representing about 17% of the known Brazilian Trichoptera fauna. Leptoceridae, Hydropsychidae, and Philopotamidae are the families most represented. The high species richness, as well as the remarkable patterns of species distribution, may be related to the characteristics of Mantiqueira mountain range. PMID:22958122

    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.

    In Peru, the industry's development has made economic improvements but at the same time, it has had a major impact on the health of the workers; for that reason, it was necessary to generate control mechanisms. So, in 1940 it was created the Departmento de Higiene Industrial, which in 1956 was changed to Instituto de Salud Ocupacional, but it was deactivated in 1994. However, in 2001 it reappeared into the Ministerio de Salud organizational structure with the name of Instituto de Salud Ocupacional "Alberto Hurtado Abadía". Actually, it is the Centro Nacional de Salud Ocupacional y Protección del Ambiente para la Salud (CENSOPAS), organ of the Instituto Nacional de Salud which continues working in synergy with other institutions and sectors, making research to protect the health of exposed persons (workers and community) to contamination and risks associated with economic activities.

    The productive character of the scientific thought points out a methodological means that include the demand of the students' job about the information and not his mere reception and reproduction. It is essential to give the students the opportunity of discovering the cognitive processes used in the production of the scientific knowledge. In this work, we present the result of the starting of a workshop dynamic in a basic subject, the students' answers, and the analysis of the subject. In the Chair of Medical Bacteriology and Virology of the School of Medical Sciences, the National University of Córdoba, 1700 students attended classes in 1997. The subject was developed with the activities that worked the same contents from two different learning conceptions: (I) workshop activity, non obligatory, constructive, and (II) theorico-practical activity, obligatory and traditional. Two voluntary and anonymous interviews were done about the valuation that the student gave to these two activities and their basis, one in the middle and the other at the end of the course. 90.55% classified the traditional activity as positive, and 9.45% as negative. Regarding the workshop activity, the 60.5% classified it as positive and the 39.5% as negative. The same developed content with two activities made possible the analysis of the impact that the two different methodologies produced on the students. The student's answer to the traditional activity was better than the workshop activity (p < 0.001). The differences in the student's acceptance between the two option revealed the major difficulty of an alternative methodological strategy in the current educational model.

    At the recently created Astronomical Museum ``Pte. Sarmiento - Dr. Benjamin Gould", the task of preventive conservation of historic documents has been faced. These materials include: 1) letters exchanged between national authorities and the directors of the Observatory, during the first decades (1870-1880-1890); b) original observation logs from these very first times, containing astrometrical and photometrical data; c) a variety of ancient books and papers; d) administrative documents. The state of conservation of this patrimony was varied: since well-conserved books and letters, to highly degraded logs. The observation logs written by B. Gould and the astronomers who followed him had been stocked in a safe with a permanent humidity of about 70 %, without any ventilation and exposed to the attack of insects of the family ``dermestidae." These conditions could not be worse for the conservation of paper. In order to stop the proccess of degradation and create a healthy environment for written-paper conservation, a team was formed with personnel belonging to the Cultural Area of the Municipality. The tasks being performed on the observation logs are: 1) an initial, mechanical cleaning, performed once the material is extracted from the contaminated safe: by these means, adult insects and pupas are removed 2) a stage of about two weeks of duration, in which the logs are mantained in a vacuum chamber, in orden to completely eliminate the adult, pupa and egg stage insects by anoxia 3) the final mechanical cleaning 4) storage in a clean location. In order to perform these tasks, we work in collaboration with the Environmental Observatory of the City, and the group of Material-Science Research of Fa.M.A.F. Regarding the letters, a mechanical cleaning was performed. After that, the letters were digitized by means of a scanner, inventoried, put inside acid-free polipropylene envelops and filed for conservation, protected from intense light and external sources of contamination. Copies of these letters will be included as exhibits.

    Higher-quality Touriga Nacional (TN) wines are characterized by a fruity-citric aroma described as sweet and fresh citrus evoking the bergamot fruit (Citrus bergamia). In fact, "bergamot-like" descriptor is currently employed to rate higher quality TN wines. The aim of this work was to identify among volatile compounds present in bergamot fruit extracts (mainly terpenes) which of them contributes the most to the bergamot overall perception, and relate these data with the volatile composition of TN wines. The identification of the most important descriptors was done by sensory analysis. Among 18 descriptors 3 were selected: bergamot-like aroma, orange like, and violet. A GCO of a typical TN wine extract allows the identification of 3 related odorant zones ZO1, ZO2, and ZO3 related with bergamot-like aroma. Using AEDA, ZO2 was confirmed to be one of the most important odorant zones. Using AEDA the presence of linalool and linalyl acetate was confirmed. A similarity test was performed with a non-TN wine added with linalool and linalyl acetate alone or in combinations. The highest similarity value was observed when linalool (SV = 5.9) was added. In fact, results obtained from the analysis of several red wines from different varieties show that terpenols are present in higher amounts in wines coming from TN variety, which proves that these compounds can be the clue to the varietal aroma of TN wines.

    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.

    The Universidad Complutense of Madrid (UCM) has recently installed a high sensitivity video system to detect meteors. It is intended to study the entry in our atmosphere of interplanetary particles of mass greater than a gram. The station, not fully equipped yet, is a node of the national Spanish Fireball Network (SPMN) and includes cameras located at the Astronomical Observatory (Physics building) and others distributed around. The system has been automated to detect and record meteors only when the atmospheric conditions are good enough. Undergraduate and graduate physics students have collaborated to develop, install and test the system. Detections which are bright enough to drop a meteorite are analyzed using double station observations with the cameras of the SPMN nodes around Spain to determine their atmospheric paths, origin and landing area.

    Developing countries suffer from brain drain for many decades. Industrialized countries have raised their barriers against immigrants, but have created mechanisms to attract foreign professionals, with aggressive policies to capture talents, in an effort to increase their competitiveness. To mitigate the effects of the migration of scientists, the Universidad Peruana Cayetano Heredia has created its own "return scholarship" about 12 years ago, and has repatriated 12 scientists through it. The funds invested in attracting the scholars total U.S. $333,540.00 and they have secured U.S. $9,249,828.42 in research funds during the same period, a figure over 27 times higher. They have published 8 articles in national journals, 68 internationally, and trained 29 undergraduate and 20 graduate students as Thesis Tutors. Other universities and institutions of our countries can emulate this successful experience, which is still evolving.

From its beginning, it incorporated anthropological and the public health contents to medical curriculum. Moreover, the formal teaching formation was reduced to 5 years, increasing the internship cycle to 2 years, with an important practice on primary health care in regional hospitals, that included a research project on health administration. A revision of the School curriculum showed the need of a better horizontal and vertical integration of medical education. Consequently, global courses were organized to gather knowledge that, until now, was delivered in a fragmented form. Our Medical School has a major impact in the southern region of the country and over 60% of its graduates have settled in this zone, improving its physician/inhabitant relationship and the number of specialists.

    Universidad de los Andes School of Medicine started in 1991 with a new medical curriculum aimed at providing a medical education for its students, that is, it attempts to give, together with technical proficiency in medical matters, formation of character and a strong ethical attitude. The curriculum lasts for seven years: five of basic, pre-clinical and clinical theoretical and practical courses, followed by two years of internships in Internal Medicine, Surgery, Obstetrics and Pediatrics, plus a four month period of an elective internship. The courses have an integrated design, in which each matter is presented from multiple perspectives, e.g. in Internal Medicine together with the clinical aspects of disease, the pathophysiology and the pharmacology of the drugs used are presented. Also the Pathology of each disease is given in coordination in the Pathology course. General educational matters such as Anthropology, Psychology, Origin of Living Beings, Theology and Medical Ethics are interspersed in the curriculum. An important feature is the personal counselling system, in which each student may choose an academic counsellor and discuss with him (her) the subjects of his choosing. Clinical practice is given in a system that includes five hospitals and five private clinics that range from general medical practice to Psychiatry or Ophthalmology.

    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.

    A CCD test-bench has been built at the Universidad Complutensés LICA laboratory. It is initially intended for commissioning of the MEGARA1 (Multi-Espectrógrafo en GTC de Alta Resolución para Astronomía) instrument but can be considered as a general purpose scientific CCD test-bench. The test-bench uses an incandescent broad-band light source in combination with a monochromator and two filter wheels to provide programmable narrow-band illumination across the visible band. Light from the monochromator can be directed to an integrating sphere for flat-field measurements or sent via a small aperture directly onto the CCD under test for high accuracy diode-mode quantum efficiency measurements. Point spread function measurements can also be performed by interposing additional optics between sphere and the CCD under test. The whole system is under LabView control via a clickable GUI. Automated measurement scans of quantum efficiency can be performed requiring only that the user replace the CCD under test with a calibrated photodiode after each measurement run. A 20cm diameter cryostat with a 10cm window and Brooks Polycold PCC closed-cycle cooler also form part of the test-bench. This cryostat is large enough to accommodate almost all scientific CCD formats has initially been used to house an E2V CCD230 in order to fully prove the test-bench functionality. This device is read-out using an Astronomical Research Camera controller connected to the UKATC's UCAM data acquisition system.

    Ecuador’s economic history has been closely linked to Theobroma cacao L cultivation, and specifically to the native fine flavour Nacional cocoa variety. The original Nacional cocoa trees are presently in danger of extinction due to foreign germplasm introductions. In a previous work, a few non-introgressed Nacional types were identified as potential founders of the modern Ecuadorian cocoa population, but so far their origin could not be formally identified. In order to determine the putative centre of origin of Nacional and trace its domestication history, we used 80 simple sequence repeat (SSR) markers to analyse the relationships between these potential Nacional founders and 169 wild and cultivated cocoa accessions from South and Central America. The highest genetic similarity was observed between the Nacional pool and some wild genotypes from the southern Amazonian region of Ecuador, sampled along the Yacuambi, Nangaritza and Zamora rivers in Zamora Chinchipe province. This result was confirmed by a parentage analysis. Based on our results and on data about pre-Columbian civilization and Spanish colonization history of Ecuador, we determined, for the first time, the possible centre of origin and migration events of the Nacional variety from the Amazonian area until its arrival in the coastal provinces. As large unexplored forest areas still exist in the southern part of the Ecuadorian Amazonian region, our findings could provide clues as to where precious new genetic resources could be collected, and subsequently used to improve the flavour and disease resistance of modern Ecuadorian cocoa varieties.

The first stage started at the end of the third decade of the twentieth century and ended in 1961, it corresponded to the conception, planning and construction of what was to be the Centro Médico del Distrito Federal (Centro Médico of the Distrito Federal) belonging to the Secretaría de Salubridad y Asistencia (Ministry of Health and Assistance). The second stage began when the Center was acquired by the Institute, then was known like Centro Médico Nacional (Centro Médico Nacional ), being put into full operation in 1963, more than twenty-two years later, in 1985, an earthquake virtually ended it, immediately began its reconstruction, finishing the second stage. In 1989 began the third stage, different and new buildings complemented or replaced the structures damaged or destroyed by the earthquake which formed the now Centro Médico Nacional Siglo XXI (Centro Médico Nacional XXI Century). In 2004 the fourth stage opened when the four hospitals of the Center were categorized like Unidades Médicas de Alta Especialidad (High Specialized Medical Units).

    GNSS navigation satellites are currently being developed by all major players in the science and technology scene, to compete with the GPS system. Because their applications span many different areas, from traffic and cargo control, to geodesy and seismic monitoring, it is required to assess the coherence between the different constellations. BDS is the GNSS system currently developed in China. Its first generation of satellites consisted of 3 geostationnary satellites allowing geolocalisation in China only. In addition to these satellites, other satellites have been launched in geostationnary and geosynchronous orbits, as well as satellites orbiting with a classical GNSS semi-major axis. With these additions, the BDS system possesses 19 operating satellites, and though the system is mostly efficient for geolocalisation in Asia, the satellites are also visible in other parts of the globe. In parallel to the development of the BDS constellation, China has launched the iGMAS (International GNSS Monitoring and Assessment Service) project to develop a global tracking network of multi-GNSS geodetic receivers. One of the goals of this project is to evaluate the efficiency of the BDS constellation as well as the efficiency of the receivers developed by the Chinese laboratories. As part of the Brazilian program COSBAN leaded by the Foreign Affairs Ministry to foster up the science and technology partnership with China, materialized by the collaboration between the Shanghai Astronomical Observatory/CAS and the Observatório Nacional/MCTI, in Rio de Janeiro. Through it the RIOS-iGMAS station was installed at Observatório Nacional, where the RJEP GNSS station already operates as part of the Brazilian reference system. Thus at the Observatório Nacional can be observed satellites from any constellation with both systems of reception, leading to a direct, efficient way to compare the results obtained for each network. In this communication we focus on the determination of the

    In 1998, stem cell research became a subject of heightened controversy. In Brazil, the polemic came to a head in 2008 when the Federal Supreme Court commenced a judicial review of the new Biosecurity Law because it permitted the use of human embryos in research. This study analyzes the coverage of human embryonic stem cell research on the national daily evening news show, Jornal Nacional . A positive tone is observed, marked by a focus on the potential benefits of the research and omission of its limitations and risks. The limited success rate thus far obtained from embryonic stem cell research and the risks of inducing the formation of tumors were omitted, intimating that the only barrier to new treatments and cures was the legislation.

    Ambient dose equivalent values were determined in several sites at the Instituto Nacional de Cancerologia, 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 {sup 137}Cs brachytherapy. Dosemeter calibration was performed at the Instituto Nacional de Investigaciones Nucleares, Laboratorio de Metrologia, to known {sup 137}Cs gamma radiation air kerma. Radionuclides considered for this study are {sup 131}I, {sup 18}F, {sup 67}Ga, {sup 99m}Tc, {sup 111}In, {sup 201}Tl and {sup 137}Cs, 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 {sup 131}I and {sup 137}Cs. High dose values were found at the waste storage room, outside corridor of {sup 137}Cs brachytherapy patients and PET/CT area. Ambient dose equivalent rate obtained for the {sup 137}Cs brachytherapy corridor is equal to (18.51{+-}0.02)x10{sup -3} mSv/h. Sites with minimum doses are the gamma camera rooms, having ambient dose equivalent rates equal to (0.05{+-}0.03)x10{sup -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).

    In 1988, the Instituto Geofisico (IG) began a permanent surveillance of Ecuadorian volcanoes, and due to activity on Guagua Pichincha, SP seismic stations and EDM control lines were then installed. Later, with the UNDRO and OAS projects, telemetered seismic monitoring was expanded to Tungurahua, Cotopaxi, Cuicocha, Chimborazo, Antisana, Cayambe, Cerro Negro, and Quilotoa volcanoes. In 1992 an agreement with the Instituto Ecuatoriano de Electrificacion strengthened the monitoring of Tungurahua and Cotopaxi volcanoes with real-time SP seismic networks and EDM lines. Thus, background activity levels became established, which was helpful because of the onset of the 1999 eruptive activity at Tungurahua and Guagua Pichincha. These eruptions had a notable impact on Baños and Quito. Unrest at Cotopaxi volcano was detected in 2001-2002, but waned. In 2002 Reventador began its eruptive period which continues to the present and is closely monitored by the IG. In 2006 permanent seismic BB stations and infrasound sensors were installed at Tungurahua and Cotopaxi under a cooperative program supported by JICA, which allowed us to follow Tungurahua's climatic eruptions of 2006 and subsequent eruptions up to the present. Programs supported by the Ecuadorian Secretaria Nacional de Ciencia y Tecnologia and the Secretaria Nacional de Planificacion resulted in further expansion of the IG's monitoring infrastructure. Thermal and video imagery, SO2 emission monitoring, geochemical analyses, continuous GPS and tiltmeters, and micro-barometric surveillance have been incorporated. Sangay, Soche, Ninahuilca, Pululahua, and Fernandina, Cerro Azul, Sierra Negra, and Alcedo in the Galapagos Islands are now monitored in real-time.

    Pontificia Universidad Católica de Chile's medical school was founded in 1929. An interest in neurosurgical development arose in the minds of the Dean, Dr. Cristobal Espíldora, and the Chief of Surgery, Dr. Rodolfo Rencoret, in 1946. They encouraged and supported Dr. J. Ricardo Olivares to specialize in Neurosurgery with Professor H. Olivecrona in Stockholm, Sweden. The first neurosurgical procedure in the Hospital Clínico de la Universidad Católica was performed in 1950. Since then, intensive efforts have been made to develop neurosurgery and its science. As a result, it is now a center capable of achieving high-quality standards in vascular, oncologic, and endoscopic neurosurgery; stereotactic and radiosurgery; complex spine surgery; pediatric neurosurgery; and epilepsy surgery. This article tells the story of a university hospital neurosurgery service in a country at the southern end of the world and how it became one of the most important neurosurgical centers in Chile and South America.

    The Centro Nacional de Aceleradores (CNA) hosts a 1 MV accelerator mass spectrometry (AMS) apparatus since September 2005. In order to improve its overall performance, several updates have been made on the existing facility during the last 10 years of operation. In this paper, two modifications conducted in 2015 will be described. To increase the transmission of the ions through the accelerator, the stripping gas on the 1 MV CNA machine was changed from Ar to He. The measured maximum transmission for almost every isotope results to be higher, especially for heavy masses: for instance, in the case of uranium in the 3+ charge state, the transmission increased from 11% with Ar gas to about 38% with He gas. The second advance consisted of the substitution of the existing gas ionization chamber with a new one provided by ETH Zurich. The ETH detector features with its miniaturized design and is optimized for low energy AMS (i.e. very low electronic noise and efficient charge collection). As the electronic noise is the most important contribution to the resolution for light ions, the total energy resolution has been reduced by 15% in the case of 10Be, allowing a better discrimination against its isobar, 10B. For the heaviest radionuclides where the quality of the spectra is determined by the charge carrier production in the gas, the resolution for 2.7 MeV uranium ions was improved by 30%, probably due to a more efficient charge collection.

    The Instituto Nacional de Enfermedades Neoplásicas was established by the government of Peru as an institution for the treatment of cancer patients in 1939; it has existed under different names until the current title was adopted in 1952. Between 1980 and 1987, attendance increased by 70% and a new and larger facility came into use at the beginning of 1988. This institution has national responsibility for cancer prevention, detection, treatment, education, and research and is currently organizing satellite treatment centers in other parts of the country. More than 80% of the medical staff has been trained in the institute's residency program, the majority of whom received additional postgraduate training in the United States and Europe; 90% of the medical staff hold academic appointments in medical schools. In 1952 the Institute became the first hospital in Peru with a formal postgraduate training system for various medical disciplines, including surgical oncology and medical oncology. So far we have trained about 500 surgical oncologists who are working in all parts of Peru. The Maes-Heller Institute for Cancer Research forms part of the National Cancer Institute complex. Research will be directed mainly toward new diagnostic and therapeutic approaches, multidisciplinary tumor therapy, and large-scale cancer screening. The Institute focuses on early detection and prevention of cancer and is active in breast self-examination education and antismoking campaigns. It enjoys community support evidenced in the women's organization, Adainen, involved in fundraising; 460 women volunteers give at least 4 hr service per week to the Institute. The Institute has grown from 9,000 patients seen per year in its early days to 215,000 attendances in 1986.

    We report first-year survival rates of 49 captive-reared Hispaniolan Parrots (Amazona ventralis) released in Parque Nacional del Este, Dominican Republic. Our goal was to learn about factors affecting postrelease survival. Specifically, we tested if survival was related to movements and whether modifying prerelease protocols influenced survival rates. We also estimated survival in the aftermath of Hurricane Georges (22 September 1998). Twenty-four parrots, fitted with radio-transmitters, were released between 14 September and 12 December 1997. Twenty-five more were released between 29 June and 16 September 1998. First-year survival rates were 30% in 1997 and 29% in 1998. Survival probability was related to bird mobility. In contrast to birds released in 1997, none of the 25 parrots released in 1998 suffered early postrelease mortality (i.e., 3-5 days after release). Two adjustments to prerelease protocols (increased exercise and reduced blood sampling) made in 1998 may have contributed to differences in mobility and survival between years. The reduction of early postrelease mortality in 1998 was encouraging, as was the prospect for higher first-year survival (e.g., 30% to 65%). Only one death was attributed to the immediate impact of the hurricane. Loss of foraging resources was likely a major contributor to ensuing mortality. Birds increased their mobility, presumably in search of food. Survival rates dropped 23% in only eight weeks posthurricane. This study underscores the value of standardized prerelease protocols, and of estimating survival and testing for factors that might influence it. Inferences from such tests will provide the best basis to make adjustments to a release program.

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

    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 highlands of northeastern Honduras remain under-characterized in terms of biological diversity, as exemplified by the regularity of new amphibian and reptile taxa discoveries. Following the recent description of a new species of Nototriton from the Sierra de Agalta in northeastern Honduras, we report the discovery of a second new species of Nototriton from the nearby Parque Nacional Montaña de Botaderos. This new taxon, Nototriton mime sp. nov., is distinguished from other Nototriton by its distinctive pale brown dorsal coloration in adult males, relatively large nares, a relatively broad head, mitochondrial sequence divergence, and phylogenetic relationships, and is geographically isolated from other populations of Nototriton.

    A distinctive new species of Atelopus is described from Parque Nacional Chirrip6 Grande, Cordillera de Talamanca (3,400-3,500 m). It closely resembles populations of the Atelopus ignescens complex from the Andes of northern Ecuador and southern Colombia. It differs most significantly from these frogs in the pattern of spiculae and coni development on the throat, chest, hands and feet. The Costa Rican species appears to be an outlier of the complex inexplicably separated geographically from its nearest allies by an over land distance of about 1,600 km.

    The career of Medicine at the Pontificia Universidad Católica de Chile was established from the beginning (1929), with a classical Flexner curriculum design. In seven years, the career is divided in three cycles: basic sciences, clinics and internship. It obtained Chilean accreditation and fulfilled American Association of Medical Colleges accreditation requirements. Changes in the Chilean epidemiological profile and health system, and new teaching methods in medicine, stimulated a process of deep curricular analysis, identifying strengths and weaknesses of the medical career. The curricular strengths were well-developed scientific and clinical components, fully committed students and faculties, well defined learning objectives and excellent clinical campuses. Curricular weaknesses included a poor vertical and horizontal integration, few student centered methodologies and a weak emphasis concerning doctor’s professionalism. Subsequently, the whole community of teachers, students and medical educators worked on the design of a new curriculum, establishing a new graduate profile and designed it oriented by learning objectives, of six years of duration, with an optimized course sequence that melds basic science and clinical concepts, with strong emphasis on humanities and professionalism. It prioritizes an early contact with patients from the first year and expands teaching methods. The main objective of this process was to achieve a new curriculum with an integrative structure. This was implemented in 2015 with an approved protocol to evaluate the outcomes.

  7. Characterizing Extrasolar Planets from Transit Light Curves obtained at the Universidad de Monterrey Observatory - Part 2

    2017-01-01

    At the Universidad de Monterrey Observatory (MPC 720) we have maintained a program for observing extrasolar planet transit light curves with telescopes of modest size and standard photometric filters since 2005. In our archives we have over 325 transits of over 70 known systems. Our goal is to combine individual transit light curves of the same system to increase the S/N of the data. We then analyze it together with the radial velocity information from the literature in order to confirm, improve or revise the main parameters that characterize the transiting system. It is important to continue observing these systems not only to improve and refine our understanding of them, but also to record any possible transient phenomenon and monitor for possible period changes, as reflected in the mid-transit times, due to the gravitational influence of additional planets in the system.In this second presentation we report our observations of 42 individual exoplanet transit light curves and the results from successfully combining six light curves for HAT-P-3 (Ic), twenty-one for TrES-3 (6 in V, 5 in Rc, 6 in Ic and 4 in z’), seven for XO-2 (Ic), four for XO-3 (Ic), and four for XO-4 (Ic). From these we then derive planet sizes (Rp/R*), orbital distances (a/R*) and orbital inclinations (i) for these systems. In most cases we confirm the parameters reported in the literature with similar uncertainties, validating our methodology. From our mid-transit times and those of the literature we do not find any statistically significant deviations from a fixed orbital period for these systems.

    A cross-sectional study that included 100 units of umbilical cord blood (UCB) was conducted to evaluate the minimum criteria of cellularity in UCB units, according to NetCord standards at Instituto Nacional Materno Perinatal in Lima, Peru. The volume, total count of nucleated cells by hematological tests and total number of CD34+ as well as cell viability by flow cytometry were determined. The study revealed that 56% of UCB units do not fulfill the minimum criteria of cellularity to be cryopreserved in an umbilical cord blood bank. Furthermore, the UCB units of newborns who weighed more and were female had a higher volume and cell count. In conclusion, these variables must undoubtedly be considered to optimize the collection of UCB units and obtain greater cell counts that enable the storage of high-quality units in a future umbilical cord blood bank in Peru.

    Radiated seismic energy is a valuable parameter in assessing the size and source characteristics of an earthquake. We study aftershocks of the 20 March 2012 earthquake (Mw7.5) in Ometepec-Pinotepa Nacional,located in the subduction zone of the Pacific coast of Mexico, with the purpose of examining the distribution of the scaled seismic energy (Es) with seismic moment (Mo), Es/Mo, over the main event's rupture area. We estimate Es from regional velocity and acceleration records. For some, larger, aftershocks we also estimate Es from teleseismic data. Preliminary energy estimations suggest that aftershocks closer to the trench have a smaller Es/Mo ratio. In contrast, Es/Mo is larger for events closer to the coast (near the epicenter of the mainshock).

    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).

It is important to continue observing these systems not only to improve and refine our understanding of them, but also to record any possible transient phenomenon (e.g. star spots) and monitor for possible period changes, as reflected in the mid-transit times, due to the gravitational influence of additional planets in the system. In this presentation we report our first results from this project. We have successfully combined light curves for HAT-P-12 (5), HAT-P-13 (7), HAT-P-16 (4), HAT-P-23 (6), and WASP-10 (8) and have derived planet sizes (Rp/R*), orbital distances (a/R*) and orbital inclinations (i) for these systems. In most cases we confirm the parameters reported in the literature with similar uncertainties, validating our methodology. However, for HAT-P-12 we have decreased the uncertainties and derived a smaller inclination for the orbit (87.9o ± 0.3o vs 89.0o ± 0.4o). Also, for HAT-P-23, the only planet in our sample with a distinct non-circular orbit, we improved the uncertainties for the eccentricity ( e ) and the argument of periastron (ω) while deriving a ~4% ± 1% smaller planet size. From our mid-transit times and those of the literature we do not find any statistically significant deviations from a fixed orbital period for these systems, although it is known that HAT-P-13 has at least a second planet.

    The present study determined through analytic techniques the quantification of some biomarkers that have been useful to detect early ethanol consumption in a college population. A group of 117 students of recent entry to the Universidad Autónoma del Estado de Morelos was analyzed. The enzyme determination of aspartate aminotransferase, alanine aminotransferase, and gamma glutamyltransferase as metabolic markers of ethanol, as well as the carbohydrate-deficient transferrin (CDT) detected by high chromatographic liquid (up to 1.8% of CDT), allowed us to identify that 6% of the college population presented a potential risk of alcohol consumption. The use of the biochemical-analytical method overall with the psychological drug and a risk factor instrument established by the Universidad Autónoma del Estado de Morelos permit us to identify students whose substance abuse consumption puts their terminal efficiency at risk as well as their academic level. The timely detection on admission to college can monitor and support a student consumer's substance abuse.

    Sponges constitute one of the most diverse and abundant animal groups in the marine tropical benthos especially in coral reefs, though poorly studied to species level. The aim of this study is to characterize the sponge community along a depth gradient at Isla Larga (Parque Nacional San Esteban, Venezuela) fringe reef. Net and total sedimentation, roughness index, sponge species richness, density and proportion of the bottom covered by sponges, were evaluated at seven depths (1, 3, 6, 9, 12, 15, 18 m), 17 species were identified grouped in 10 demosponges families. The highest densities and coverage corresponded to 6 m of depth (6.03ind/m2; 11%), that coincides with the lowest net sedimentation and highest substrate heterogeneity. Most abundant species were Desmapsamma anchorata, Amphimedon erina and Scopalina rueztleri. Principal component analysis divided this community in three zones according to depth. The shallow zone of the reef (1 and 3 m), where wave force and high irradiance exert a constant stress sponges, shows the lowest density and coverage by sponges. In contrast, medium depth (6, 9 y 12 m) and deep zone (15 y 18 m) with lower light and sedimentation levels seem to enhance sponge growth and survival that are reflected on the higher densities and coverage of sponges.

    Annular pancreas (AP) is a rare congenital anomaly due to malrotation of the pancreatic ventral yolk. Although it has been described in young and middle age adults it predominates in children. Its clinical picture is that of duodenal obstruction or acute pancreatitis episodes. In this paper we report four cases of AP that were seen at the Instituto Nacional de la Nutricion Salvador Zubiran in Mexico City. Three were females and three were less than twenty years old. In one case the diagnosis was established at birth and the operation done in another hospital. In another patient a diagnosis of pyloric hypertrophy was made and a pyloroplasty was performed. This young man was admitted in our hospital because of abdominal pain and hyperamylasemia. An eighty four year old woman was seen due to abdominal pain, nausea and vomit. In all cases the diagnosis of AP was carried out with radiological studies and confirmed by laparotomy. Surgical procedures consisted of duodenal-duodenal anastomosis in two, sphincteroplasty in one, and gastrojejunoanastomosis in the other. Two patients are asymptomatic, one died in the postoperative period, and one was lost for follow up. These four cases represent all the experience of our institute and correspond to one case in 36,735 admissions.

    We evaluated 500 endoscopic retrograde cholangiopancreatographies (ERCP) performed on 422 patients during a 5-year period in the Gastrointestinal Endoscopy Department, Instituto Nacional de la Nutrición Salvador Zubirán, México, D.F. ERCP combines endoscopic and radiologic techniques in order to obtain high quality opacification of pancreatic and biliary ducts. The rate of success for cannulation was 90%; desired duct opacification was possible in 89%. The most frequent indication for ERCP was to establish the differential diagnosis for jaundice; biliary stones in the common bile duct was the most frequent diagnosis, followed by normal biliary ducts. Pancreatography was normal in 74% of patients. ERCP complications were detected in 5.6%; fever and transient pain was the most common complaint in 1.6%. Mortality attributable to the procedure was 0.8%. From histological corroboration of cases by surgery or postmortem studies, diagnostic sensitivity was 92%, specificity 76%, positive predictive value 96% and a prevalence of 89%. We conclude that ERCP is highly sensitive and specific in diagnosing bilio-pancreatic-duodenal disease. Our results are comparable to other's experiences published throughout the world.

    ABSTRACT OBJECTIVE Our main objective was to analyse how the evolution of household assets ownership affected the Indicador Econômico Nacional (IEN – National Wealth index) and to point out the most stable assets and which lost importance more quickly. METHODS We analysed the trend of the ownership of each IEN variable and the distribution of the households’ scores. We calculated the correlation coefficients of each variable separately with the IEN score and the household income. We also evaluated how the changes of the score distribution over time affected the validity of the published reference cut-points. We used data from consortium surveys conducted every two years from 2002 to 2014 in the city of Pelotas, Brazil. RESULTS An increase in the educational level of household heads and in the ownership of all IEN assets, except radio and telephone, was observed in the study period. In general, the correlation of the assets with the IEN scores decreased over time. There was an increase in the score, with a consequent increase in the quintiles cut-points, but the distance between these cut-points had no significant variation. Thus, the reference cut-points for Pelotas, quickly became outdated. CONCLUSIONS Some assets showed greatly reduction on its importance for the indicator, and the reference cut-points became obsolete very quickly. It is essential for a standardized wealth (or asset) index with research purposes to be updated frequently, especially the cut-points of reference distribution. PMID:28273231

    This article investigates the relationships between ceroplastics and the institutionalization of forensic medicine as a discipline at the Faculty of Medicine, Universidade de São Paulo, Brazil. The wax models, representing diseases or body parts that were the subject of medical forensic investigation, were produced by Augusto Esteves between 1936 and 1960. It is believed that the ceroplastic production represented the program devised by Flamínio Fávero, full professor of forensic medicine between 1923 and 1955. The comparison between the wax pieces at Museu Técnico-Científico (a science and technology museum) at Instituto Oscar Freire and the treatise on forensic medicine by Fávero, first published in 1938, indicates that such a supposition is plausible.

    This study presents the results of a research that examined the use and attitudes about alcohol, tobacco, coca leaves, tranquilizers and amphetamines among nursing students at the Universidad Mayor de San Andrés who had not used these substances over the last 12 months. Data were collected in August 2002 by means of a self-administered and distributed questionnaire, which guaranteed anonymity. The following results were obtained: Attitudes related to drugs approve of coca leaf and tranquilizer use and disapprove of cocaine. Personal use of drugs during the last 12 months corresponds to: daily use of coca leaves, alcohol less than once per week and tobacco every day. The main reason for using these drugs is related to religious practice; the students' first contact with drugs occurs through family members and (girl or boy) friends.

    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.

    Introducción: en apoyo a la problemática de sobrepeso y obesidad en México, en el 2010 se publicó el Acuerdo Nacional para la Salud Alimentaria. A nivel escolar, los comodatarios se consideraron fundamentales para cumplir con ciertos compromisos. El objetivo de esta intervención fue capacitar a comodatarios de los Establecimientos de Consumo Escolar (ECE) en cuanto a los criterios establecidos en los “Lineamientos Generales para el Expendio y Distribución de Alimentos en Planteles de Educación Básica.” Métodos: participaron 13 ECE en San Luis Potosí. Con base en un diagnóstico inicial, se diseñó un curso-taller de 5 sesiones. Se evaluaron conocimientos en materia alimentaria al inicio y al final de las sesiones. Se obtuvo el porcentaje de apego en cuanto a higiene general, preparación y distribución de alimentos, al inicio, al mes y a los dos meses postintervención. Resultados: los comodatarios presentaron pocos conocimientos en los objetivos que persigue el “Acuerdo” en grupos y combinación de alimentos así como en lectura de etiquetas; con cambios significativos en los dos últimos tras la intervención. El porcentaje inicial de cumplimiento en higiene general fue del 60 %, con un incremento de casi 20 % postcapacitación. La preparación y distribución de alimentos no presentaron cambios significativos. Conclusiones: los comodatarios adquirieron conocimientos sobre los lineamientos que debe cubrir un ECE, sin ponerlos en práctica, dado el impacto que ello implica en su economía.

    The superficial mycoses are very common infectious diseases and therefore are a frequent reason for medical consultation. The aim of this study was to determine the diagnostic frequency of superficial mycoses in the Mycology Department of the Instituto Nacional de Higiene "Rafael Rangel" during 14 years (2001-2014). A retrospective cross-sectional study was performed to review the mycological records of patients with presumptive diagnosis of superficial mycosis. Nails, hairs and epidermal scales were the processed samples. The identification of fungi was performed by macro and microscopic observation of colonies and biochemical and physiological tests, as required of the isolated agent. For the investigation of Malassezia spp. only direct examination was performed. Of the 3 228 samples processed, 1 098 (34%) were positive and their distribution according to the etiological agent was: dermatophytes 79.5%; 10.9% yeasts; non-dermatophytes fungi 5.1% and 4.5% Malassezia spp. The most frequently isolated dermatophyte was Trichophyton rubrum Complex (70.1%), followed by T mentagrophytes complex (15.1%), Microsporum canis (9.4%) and Epidermophyton floccosum (4%). The most frequent ringworms Were: Tinea unguium (66.8%), followed by Tineapedis (16.4%) and Tinea capitis (8.1%). Candida parapsilosis complex (37.5%) was the most frequently isolated yeast and Fusarium spp. (53.6%) was the most isolated among non-dermatophyte fungi, followed by Aspergillus spp. (19.6%) and Acremonium spp. (10.7%). The identification of the etiological agent is essential to guide appropriate treatment. This study constitutes an important contribution to the knowledge of the epidemiology of superficial mycoses in our country.

  7. Differential physiological response of the grapevine varieties Touriga Nacional and Trincadeira to combined heat, drought and light stresses.

    Worldwide, extensive agricultural losses are attributed to drought, often in combination with heat in Mediterranean climate regions, where grapevine traditionally grows. The available scenarios for climate change suggest increases in aridity in these regions. Under natural conditions plants are affected by a combination of stresses, triggering synergistic or antagonistic physiological, metabolic or transcriptomic responses unique to the combination. However the study of such stresses in a controlled environment can elucidate important mechanisms by allowing the separation of the effects of individual stresses. To gather those effects, cuttings of two grapevine varieties, Touriga Nacional (TN) and Trincadeira (TR), were grown under controlled conditions and subjected to three abiotic stresses (drought - WS, heat - HS and high light - LS) individually and in combination two-by-two (WSHS, WSLS, HSLS) or all three (WSHSLS). Photosynthesis, water status, contents of H2 O2 , abscisic acid and metabolites of the ascorbate-glutathione cycle were measured in the leaves. Common and distinct response features were identified in the different stress combinations. Photosynthesis was not hindered in TN by LS, while even individual stresses severely affect photosynthesis in TR. Abscisic acid may be implicated in grapevine osmotic responses since it is correlated with tolerance parameters, especially in combined stresses involving drought. Overall, the responses to drought-including treatments were clearly distinct to those without drought. From the specific behaviours of the varieties, it can be concluded that TN shows a higher capacity for heat dissipation and for withstanding high light intensities, indicating better adjustment to warm conditions, provided that water supply is plentiful.

    We describe the fourth species of nurse-frog genus Allobates occurring in the southeastern Brazilian Amazonia. The new species is sympatric with Allobates femoralis, Allobates masniger and Allobates magnussoni, and inhabits the margins of streams in forested areas within Parque Nacional da Amazônia, on the western bank of the Tapajós River. Snout-to-vent length ranges between 14.9-16.1 mm among males and 15.6-16.5 mm among females. The species is distinguished by the light brown background color of dorsum, with irregular dark brown blotches appearing from eye level to the urostyle region. In life, ventral surfaces of males are golden yellow on throat and chest, and white to yellow on abdomen. Ventral surfaces of females are predominantly white, except for light yellow on chin. The dark brown lateral band has a diffuse lower edge ventrolaterally. Dorsal surface of thigh is cream, with a longitudinal dark brown band extending dorsally from vent to knee. Tail musculature of tadpoles is robust, bifurcating dorsally over the body and reaching about two-thirds of the body length. Advertisement calls consist predominantly of continuous pairs of notes, but other note arrangements are also emitted. Notes have ascending frequency modulation and average peak frequency ranging between 5.3-5.9 kHz. First and second notes of the same note pair are similar in amplitude, duration and frequency spectrum. Successive note pairs are split by approximately regular silent intervals (0.30-0.49 s). The species lays its eggs inside rolled or folded dead leaves on the leaf litter. Egg capsules and jelly nests are opaque.

    The Bologna process is to improve the quality of education, mobility, diversity and the competitiveness and involves three fundamental changes: transform of the structure of titles, changing in methods of teaching and implementation of the systems of quality assurance. Engineer Agronomist at the Universidad Politécnica de Madrid (UPM) has been offered as a degree of five years with a total of 400 credits and seven optional orientations: Crop Production, Plant and Breeding Protection, Environment, Agricultural Economics, Animal Production, Rural Engineering and Food Technology. Actually, the Bologna plan creates three new degrees: Engineering and Science Agronomic, Food Engineering and Agro-Environmental Engineering, with 240 ECTS each one of them and with specific professional characteristics. The changes that involve the introduction of these new degrees is perhaps the largest occurred never at the Spanish university system, not only by the drastic transformation in the structure of titles, but also by the new changes that lie ahead in teaching methods. Among others we will comment the following ones: -A year decreased duration of studies and therefore incorporation into the market. - Elimination of the seven current guidelines to create three specific qualifications of degree. -Decrease of optional subjects and increase in credits for the basic subjects. - Inclusion of business practices. - Increase in the number of credits of final project. - Changes in methodologies and a higher involvement of teachers and students in the education.

    Objective To analyze the Educational Project of the undergraduate medical course to verify what is taught regarding Patient Safety and to enable reflections on the educational practice. Methods A descriptive study, using document research as strategy. The document of investigation was the Educational Project of the medical course, in 2006, at the Escola Paulista de Medicina of the Universidade Federal de São Paulo. The theoretical framework adopted was the Multi-Professional Patient Safety Curriculum Guide of the World Health Organization, which led to the preparation of a list with 153 tracking terms. Results We identified 65 syllabus units in the Educational Project of the course, in which 40 (61.5%) addressed topics related to Patient Safety. Themes on the topic “Infection prevention and control” were found in 19 (47.5%) units and teaching of “Interaction with patients and caregivers” in 12 (32.5%); however content related to “Learning from errors to prevent harm” were not found. None of the framework topics had their proposed themes entirely taught during the period of education of the future physicians. Conclusion Patient safety is taught in a fragmented manner, which values clinical skills such as the diagnosis and treatment of diseases, post-treatment, surgical procedures, and follow-up. Since it is a recent movement, the teaching of patient safety confronts informative proposals based on traditional structures centered on subjects and on specific education, and it is still poorly valued.

    Ongoing changes in the social, economic, technological and scientific realms have generated new needs and led various organizations to suggest that educational institutions should reorient their educational strategies toward developing effective professionals with the skills to meet these needs. These "modern" strategies include problem-based learning, in which the student seeks and selects information, analyzes the data obtained, integrates both prior and newly acquired knowledge, and, finally, offers diagnostic and therapeutic options to resolve the problem posed, as would occur in professional practice. With this approach, prior skills and practical experience form the foundation of learning. Problem-based learning incorporates some aspects of cognitive psychology, a model that mainly centers on the nature of the knowledge structures found in active memory, the processes involved in information storage and retrieval and the various factors that activate these processes. At the Faculty of Medicine of the Universidad de Castilla-La Mancha, urology is part of a core subject (Medical and Surgical Pathology II) taught in the fifth year of coursework together with nephrology. Each course includes approximately 75 students, divided into five groups. The rotation lasts six weeks, with students spending a mean of two hours a day on theory (nephrology and/or urology) and the remaining time on rotations in the various activities: three weeks in nephrology and three weeks in urology. Upon completion of the rotation, the students write a combined theoretical examination with 100 multiple-choice questions (50 on urology) and take a practical skills examination. At the end of the course, another practical test consisting of an objective, structured clinical examination is taken, in which standard patients are used and the professor directly assesses the level of skills acquired with a "real" case.

    Reported associations between the consumption of fried foods and the incidence of obesity or weight gain make it likely that fried food consumption might also be associated with the development of hypertension. However, evidence from long-term prospective studies is scarce. Therefore, the aim of the present study was to longitudinally evaluate this association in a prospective cohort. The SUN (Seguimiento Universidad de Navarra) project is a Mediterranean cohort study of university graduates conducted in Spain, which started in December 1999 and is still ongoing. In the present study, we included 13,679 participants (5059 men and 8620 women), free of hypertension at baseline with a mean age of 36·5 (SD 10·8) years. Total fried food consumption was estimated at baseline. The outcome was the incidence of a medical diagnosis of self-reported hypertension during the follow-up period. To assess the association between the consumption of fried foods and the subsequent risk of developing incident hypertension during the follow-up period, Cox regression models were used. During a median follow-up period of 6·3 years, 1232 incident cases of hypertension were identified. After adjusting for potential confounders, the adjusted hazard ratios for developing hypertension were 1·18 (95% CI 1·03, 1·36) and 1·21 (95% CI 1·04, 1·41) for those consuming fried foods 2-4 and >4 times/week, respectively, compared with those consuming fried foods < 2 times/week (P for trend = 0·009). In conclusion, frequent consumption of fried foods at baseline was found to be associated with a higher risk of hypertension during the follow-up period in a Mediterranean cohort of university graduates.

    In a study conducted in the gallery forest of the Vale doVeu de Noiva in the Parque Nacional da Chapada dos Guimarães, Mato Grosso state, chemical baits were used to attract and sample male orchid bees. From September 2003 to July 2005, male euglossine bees were captured monthly, from 8:00 a.m. to 4:00 p.m. as they arrived at the baits. Of the 264 males captured, eight males belonged to Aglae caerulea Lepeletier & Serville, a cleptoparasitic euglossine species that presumably occurred only in the Amazon basin. Therefore, the occurrence of A. caerulea in this study area extends its geographical distribution range by approximately 2,400 km southwards in South America, as it is now recorded in both the Amazon and Platina basins.

    The development of scientific health research requires a sustained and articulated research system that is consistent with the research priorities, as well as both internal and external funding, and availability of competent human resources. The Mining Canon, a constitutional right, has been partly used to foster applied scientific research in public universities (PU). In addition, the National Health Institute (INSTITUTO NACIONAL DE SALUD - INS) is devoted, among others, to promoting, managing and disseminating health research development at a national level. As part of these activities, a technical team was created to provide technical assistance to PU for research development using Mining Canon funds by making local adjustments to research protocols promoted by the INS and assumed by the professors-researchers at the Universities. This article aims at describing the reality of research at Peruvian public universities that have access to Mining Canon funds, as well as to elaborate on the work the INS is carrying out in order to strengthen research capabilities, starting with the development of research proposals that could potentially be funded by the Mining Canon.

    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.

    The purpose of this study was to determine the frequency of different Central Nervous System Tumors (CNST) diagnosed at the Instituto Nacional de Neurología y Neurocirugía (National Institute of Neurology and Neurosurgery) from Mexico City over a 10-year period (1990 to 1999) by means of a hospital survey. This institute is a reference hospital that provides medical attention to a very high number of adult neurological patients every year (approximately 6,000 new patients per year besides emergency cases). From a total number of 2,041 CNST cases, we found that the most frequent tumors were those affecting the neuroepithelial tissue (32.8 %), followed by tumors of the anterior pituitary gland (26.2 %) and tumors of the meninges and similar tissues (24.1 %). In both, male and female patients the higher frequency of CNST was found in patients whose age ranged from 25 to 44 years, and CNST were slightly more frequent in women than in men. Most of the CNST patients lived in the southern districts of Mexico City, it could be because of the great number of people living in the southern districts of the city, or perhaps due to the presence of certain yet unidentified environmental carcinogenic substance in this area. Since CNST are among the more frequent malignant neoplasms, it is necessary to improve the registration system to include frequency, prevalence, incidence and mortality of these diseases in Mexico, in order to plan health policies like in developed countries.

    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.

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.

    The quality of care has always been a subject of interest to the Instituto Nacional de la Nutrición "Salvador Zubirán", in order to improve its services. This interest led to the present survey which aims to evaluate the patient's global satisfaction and to identify specific problems susceptible of improvement. One hundred and seventy-one patients or relatives attending eight different services of the Institute were interviewed. Opinions about the following aspects were explored by means of service-specific questionnaires: sociodemographic characteristics, satisfaction with care, waiting periods, patient-personnel relationship, hospital environment, food quality, drug availability and costs. Results of the survey show a high level of satisfaction with the services provided, i.e. 33% of the patients considered it good, and 64% excellent. However, and in agreement with other reports, this high level of satisfaction does not necessarily reflect an absence of problems, i.e. long waiting periods, insufficient restrooms, failures in getting information about their health status, and occasional absence of drugs in the pharmacy were identified. Continuation of this kind of surveys in our setting leads not only to the identification of problems, but also to the evaluation of the impact that resulting measures may have on the patient's satisfaction.

    Comparison of clinical and autopsy findings of the cases studied between 1984 and 1988, were made at the Department of Pathology of the Instituto Nacional de la Nutricion Salvador Zubiran in Mexico City. The goal was to determine the accuracy of clinical diagnoses. The total number of cases was 429. A decreasing number of autopsies as a function of time was observed. Thus, in 1985, 34.65% of the deaths was autopsied, whereas in 1988, the number dropped to 21.16%, overall mean of 27.31%. In 229 autopsies (53.8%), 353 findings of clinical significance were found; of these, 86 were in the main diagnoses and 267 in the causes of death. There were 171 overdiagnoses with therapeutic implications, 38 in the main diagnoses and 133 in the causes of death. Overdiagnoses and underdiagnoses were most common in infectious diseases, followed by respiratory and digestive diseases, while endocrinologic and rheumatologic diseases had the highest diagnostic concordance. It was also found that the diagnostic accuracy did not improve with time of hospitalization. A brief analyses of the probable causes of the decrease in the number of autopsies is made. It is concluded that, in spite of the great advances in clinical and technological knowledge, the high frequency of disagreements between clinical and anatomical diagnoses, indicate that autopsy continues playing a key role in the quality control of medical practice. This justifies by itself the performance of necropsies.

    We use near-field accelerograms recorded by the very broadband seismographic station of PNIG to locate the Pinotepa Nacional earthquake of 27 March, 1996 (Mw = 5.4) and to determine its source parameters. The data from PNIG on P and S arrival times, the azimuth of the arrival of P wave, and the angle of incidence of the P wave at the free surface permit the determination of the location (16.365° N, 98.303° W, depth = 18 km) and the origin time (12:34;48.35) of the earthquake.The displacement seismograms of the earthquake clearly shows contribution from the near-field terms. We compute a suite of synthetic seismograms for local mechanisms in the vicinity of the mechanism reported by the U.S. Geological Survey (USGS) and compare them with the observed seismograms at PNIG. The point whose synthetics fit the observed records well has the following parameters: seismic moment, M0 = 1.2 × 1024 dyne-cm; source time function: a triangular pulse of 0.9 sec duration; fault plane: strike = 291°, dip = 10°, and rake = 80°. The location and the source parameters obtained from the analysis of PNIG records differ significantly from those reported by the USGS. This demonstrates again, what has been shown by some previous researchers, that high-quality recordings from a single near-field station can considerably improve the estimation of the source parameters of an earthquake.

    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.

    The spectral classifiers allow a good estimate for the mapping of the materials from the similarity between the reference curve and the image. Initially the spectral classifiers had been developed for hyperspectral images analysis. However, some works demonstrate good results for the application of these techniques in multispectral images. The present work aims to evaluate the spectral classifier Spectral Identification Method (SIM) in ASTER image. The Spectral Identification Method (SIM) is proposed to establish a new similarity index and three estimates according to the significance of regression (5%, 10% and 15%) of the materials. This method is based on two statistical procedures: ANOVA and Spectral Correlation Mapper (SCM) coefficient. This information can be used to evaluate the degree of correlation among the materials in analysis. The advantage of this method is to validate according to significance of regression most probable areas of the sought material. The method was applied to ASTER image at the Parque Nacional (DF - Brazil). The images were acquired with atmosphere correction. The pixels size from the SWIR image was duplicated in order to join the VNIR and SWIR images. Endmembers were detected in three steps: a) spectral reduction by the Minimum Noise Fraction (MNF), b) spatial reduction by the Pixel Purity Index (PPI) and c) manual identification of the endmembers using the N-dimensional visualizer. The classification was made from the endmembers of nonphotosynthetic vegetation (NPV), photosynthetic vegetation (PV) and soil. These procedures allowed identifying the main scenarios in the study area.

    The goal of this study was to identify the degree of knowledge of students and health educators on licit and illicit drugs, related to the type, classification, action, mechanisms damages, consequences and adverse effects, besides use and consumption. A cross-sectional methodological design was used, with a sample of 172 students, professors and residents in medicine and nursing at Universidad Mayor de San Andrés (UMSA), Bolivia. The results reveal weak knowledge on the classification of psychotropic substances according to structure, chemical property and effects for health, highlighting significant difference with knowledge on licit and illicit drugs use, with high percentages. In conclusion, there is lack of knowledge in all groups studied on licit and illicit drugs regarding the consequences and adverse effects. This confirms the need to improve teaching on this content in health schools.

    Research is a main element for human and social development. Under this point of view, it involves particular challenges and opportunities for the so-called "developing countries". An approach for those challenges and opportunities comes from the analysis of two interrelated activities; the training of new researchers and the research development with institutions or researchers which are external to the institution ("collaborative research"). Both activities are essential for the consolidation, widening and updating of the institutional capabilities for scientific production. We present here the experiences of the Instituto de Medicina Tropical "Alexander von Humboldt" of the Universidad Peruana Cayetano Heredia, in relation to the training of new researchers, we discuss the four elements we consider key for this process; the promotion of stimulating environments for research, the proactive identification of fellows, the complementary advice and networks consolidation; and we analyze three successful models of international collaboration for the training of new researchers under different institutional approaches.

    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.

    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.

    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 {λ}/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.

    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.

  8. A atuação do Observatório Nacional registrada nos relatórios ministeriais 1889 a 1930

    Rodrigues, T.

    2003-08-01

    O período republicano até 1930 foi marcante na história do Observatório Nacional. Diversas reformas levaram a instituição a três ministérios diferentes e mudaram a ênfase do seu trabalho. A tão aguardada mudança para uma nova sede, em São Cristóvão, em 1920, não foi suficiente para que a instituição acompanhasse o ritmo tomado pela astronomia no mundo e se firmasse como ambiente de pesquisa. Uma análise simplificada poderia caracterizar um período de produção científica insignificante, dado o distanciamento da instituição dos novos rumos da astrofísica e da rápida inovação dos instrumentos, além do pequeno volume de publicações. Era uma época em que ainda não existiam os mecanismos formais de apoio e avaliação da atividade científica. Esse trabalho procura identificar a real atividade do Observatório no conteúdo dos Relatórios Ministeriais que, ao final de cada ano, apresentava as atividades, sucessos e problemas enfrentados pela instituição. Questões como instrumental e recursos humanos necessários; entraves burocráticos e financeiros; e articulações com outros observatórios se complementaram entre si ao longo desses anos para definir o perfil institucional e alguns aspectos fundamentais para a construção da astronomia no país. É possível concluir que a ênfase em serviços geográficos e de meteorologia, ao lado da inadequação dos instrumentos e do local, quase fizeram desaparecer a pesquisa em astronomia. Porém, vale destacar a sobrevivência de alguns trabalhos, como, por exemplo, variação de latitude e observação de estrelas duplas que mantiveram importante intercâmbio com outros grupos de pesquisa, demonstrando o constante esforço dos astrônomos e das diretorias em defesa da atividade científica.

    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

    As part of an institutional program sponsored by the Centre for Teaching Excellence at the Universidad del Norte, Barranquilla, Colombia, we developed an educational research study on two sessions of human anatomy in which we combined team-based learning (TBL) and the use of iPads. Study data included the TBL, assessments applied during the course, student's grades on mid-term examinations and students' perceptions of their experiences. Students reported a positive attitude toward the use of the TBL sessions, and the results showed a significant improvement in their learning between the first and second sessions. Significantly positive correlations (P < 0.05) were obtained between (a) the individual students' readiness test performance 1 and mid-term examination 1, (b) the individual readiness test performances from Session 1 to Session 2, and (c) the group readiness test performances from the first and second sessions. These results point to positive learning experiences for these students. Analyses of the students' reflections on their activities also pointed toward future challenges.

    An analysis of scientific bibliographic productivity using the Hirsch h-index, information from the Institute of Scientific Information database and the Curriculum Lattes (CNPq, Brazil) was performed at the Faculdade de Filosofia, Ciências e Letras de Ribeirão Preto, Universidade de São Paulo (FFCLRP-USP) that has four departments in natural, biological and social sciences. Bibliometric evaluations of undergraduate programs showed a better performance of the departments of Chemistry (P < 0.001) and Biology (P < 0.001) when compared to the departments of Physics and Mathematics and Psychology and Education. We also analyzed the scientific output of the six graduate programs of FFCLRP: Psychology, Psychobiology, Chemistry, Physics Applied to Medicine and Biology, Comparative Biology, and Entomology. The graduate program in Psychology presented a lower h-index (P < 0.001) and had fewer papers indexed by the ISI web of science (P < 0.001) when compared to the other graduate programs. The poorer performance of the Psychology program may be associated with the limited coverage by the Thompson Institute of Scientific Information database.

    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.

    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.

    Since 1974, the Bachelor of Biomedical Engineering Program (BBME) is offered at Universidad Autónoma Metropolitana-Iztapalapa, in Mexico City. By design, it must be completed in four years (12 trimesters) and, in the latter three, the senior students work on a BME project, which is done by completing three modules: Project Seminar (PS), Project on BME I and Project on BME II. In the PS module, the student must find a problem of interest in the BME field and suggest a solution through the development of an Engineering Project Proposal (EPP). Currently, the module is being taught by two faculty members of the BBME, who instruct students on how to develop their EPPs and evaluate their progress by reviewing a number of EPPs during the trimester. This generates a huge workload for the module instructors, which makes it necessary to involve more faculty members trimester-to-trimester (i.e. every 12 weeks) and, therefore, to create a set of systematic guidelines that ease the evaluation process for new instructors. Hence, the purpose of this paper is to present an assessment strategy (in the form of an assessment matrix) for the PS module as well as some preliminary results after two trimesters of its implementation.

    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.

    Epidemiological research confirms that the prevalence of suboptimal micronutrient intakes across Europe is an emerging concern in terms of public health. The aim of the present study was to investigate the association between a new index of carbohydrate (CHO) quality and micronutrient intake adequacy in the 'Seguimiento Universidad de Navarra (SUN)' cohort. The baseline assessment extended from 1999 to March 2012. We assessed 16,841 participants who completed a validated 136-item semi-quantitative FFQ at baseline. We created a new index to evaluate CHO quality for the following four criteria: dietary fibre intake; glycaemic index; whole grains:total grains ratio; solid CHO:total CHO ratio. The subjects were classified into quintiles according to this index. We evaluated the intakes of Zn, I, Se, Fe, Ca, K, P, Mg, Cr and vitamins B1, B2, B3, B6, B12, C, A, D, E and folic acid. The probability of intake adequacy was evaluated using the estimated average requirement cut-point approach and the probabilistic approach. Logistic regression analysis was used to assess the nutritional adequacy according to the CHO quality index (CQI). Participants in the highest quintile of CQI were found to have the lowest prevalence of inadequacy. A higher quality of CHO intake was found to be associated with a lower risk of nutritional inadequacy in comparison with the lowest quintile of CQI (adjusted OR 0·06, 95 % CI 0·02, 0·16; P for trend < 0·001). A higher CQI was found to be strongly associated with better micronutrient intake adequacy in the young Mediterranean cohort, stressing the importance of focusing nutritional education not only on CHO quantity, but also on quality.

    There is evidence that a diet rich in fruit and vegetables reduces blood pressure (BP). Characteristically, the Mediterranean diet is rich in plant-derived foods and also in fat, but studies conducted in Mediterranean countries to relate diet to BP are scarce. We studied the association between fruit and vegetable consumption and BP in a cross-sectional analysis of 4393 participants in the Seguimiento Universidad de Navarra (SUN) Study, an ongoing dynamic cohort study in Spain. Diet was measured using a food-frequency questionnaire previously validated in Spain. Fat represented more than 37 % total energy intake. Subjects were considered to have undiagnosed hypertension if they reported systolic BP > or = 140 mmHg or diastolic BP > or = 90 mmHg, and not a medical diagnosis of hypertension. The adjusted prevalence odds ratio of undiagnosed hypertension (upper v. lowest quintile) was 0.58 (95 % CI 0.36, 0.91; P for trend 0.01) for vegetable consumption and 0.68 (95 % CI 0.43, 1.09; P for trend 0.10) for fruit consumption. Comparing those in the highest quintile of both fruit and vegetable consumption with those in the lowest quintile of both food groups, the prevalence odds ratio was 0.23 (95 % CI 0.10, 0.55; P = 0.001), after adjusting for risk factors for hypertension and other dietary exposures. In a Mediterranean population with an elevated fat consumption, a high fruit and vegetable intake is inversely associated with BP levels.

    Polychlorinated biphenyls are persistent organic pollutants that are consumed because of their bioaccumulation through the food chain. Evidence from different sources suggests a positive association between polychlorinated biphenyls exposure and the incidence of hypertension. However, no previous prospective study has investigated this potential relationship in adults. We prospectively assessed the association between dietary intake of polychlorinated biphenyls and the incidence of hypertension in a large cohort. The Seguimiento Universidad de Navarra project is a Spanish cohort of university graduates, most of them health professionals. We included 14521 participants, initially free of hypertension, who were followed-up for a median of 8.3 years. Dietary intake of polychlorinated biphenyls was assessed at baseline through a previously validated 136-item semiquantitative food frequency questionnaire. The published concentration levels of polychlorinated biphenyls measured in samples of food consumed in Spain were used to estimate dietary intake. Multivariable Cox regression models were fitted to estimate hazard ratios and 95% confidence interval for incident hypertension. During follow-up, 1497 incident cases of medically diagnosed hypertension were identified. After adjusting for total energy intake and for potential confounders, participants in the fifth quintile of total polychlorinated biphenyls intake were at higher risk of developing hypertension (adjusted hazard ratio, 1.43 [95% confidence interval, 1.09-1.88; P for trend 0.017]) compared with those in the first quintile. In this Mediterranean cohort, dietary intake of polychlorinated biphenyls, estimated using a food frequency questionnaire, was associated with a higher risk of developing hypertension during follow-up. Nevertheless, further longitudinal studies are needed to confirm our results.

    The Master in Space Science and Technology is a postgraduate course at the Universidad del País Vasco in Spain (http://www.ehu.es/aula-espazio/master.html). 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.

    INTRODUCTION The scientific production of institutions of higher education, as well as the dissemination and use of this published work by peer institutions, can be assessed by means of quantitative and qualitative measurements. This type of analysis can also serve as the basis of further academic actions. Variables such as the type of evaluation, the number of faculty members and the decision to include or exclude researchers who are not professors are difficult to measure when comparing different schools and institutions. OBJECTIVES The purpose of this study was to assess the scientific production of tenured faculty from the Universidade de São Paulo, Faculdade de Medicina performed from 2001 to 2006. METHODS Medline/PubMed database was considered and the Impact factors (IFs - Journal Citation Report, 2006) and the number of generated citations (Web of Science/ISI Thomson) were also evaluated. RESULTS The analysis of the scientific production of 66 full professors (level MS-6) revealed 1,960 scientific articles published in 630 scientific journals, of which 31.3% were Brazilian and 68.7% were from international sources. Among these, 47% of the articles were published in 62.9% of the journals with IFs above 10, although 16.4% of the journals did not have assigned IF values. We verified that 45% of the published articles received 9,335 citations (average of 11 + 17), with the majority of these (8,968 citations) appearing in international scientific journals. CONCLUSIONS Our results indicate that it is possible to analyze the scientific production of a learning institution by the number of papers published by full professors, taking into account not only their academic position and influence, but also the fact that publication is an opportunity to stimulate joint projects with other members of the same institution.

    Herein we catalogue all geckos (Gekkonidae, Phyllodactylidae and Sphaerodactylidae) collected by Roberto Donoso-Barros in Venezuela between 1963 and 1964, deposited in the Universidad de Concepción in Chile. Donoso-Barros did not provide detailed descriptions of two species of Gonatodes named by him, despite both being valid species. We take the opportunity to do so and the type series of Gonatodes ligiae and G. petersi are described for the first time. We also present images in life of all species collected by Donoso-Barros in Venezuela.

    Ramos Pastrana, Nilsa

    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?

    This consensus document was prepared by an expert panel of the Grupo de Estudio de Sida (GESIDA [Spanish AIDS Study Group]) and the Plan Nacional sobre el Sida (PNS [Spanish National AIDS Plan]). The document updates current guidelines on the treatment of tuberculosis (TB) in HIV-infected individuals contained in the guidelines on the treatment of opportunistic infections published by GESIDA and PNS in 2008. The document aims to facilitate the management and treatment of HIV-infected patients with TB in Spain, and includes specific sections and recommendations on the treatment of drug-sensitive TB, multidrug-resistant TB, and extensively drug-resistant TB, in this population. The consensus guidelines also make recommendations on the treatment of HIV-infected patients with TB in special situations, such as chronic liver disease, pregnancy, kidney failure, and transplantation. Recommendations are made on the timing and initial regimens of antiretroviral therapy in patients with TB, and on immune reconstitution syndrome in HIV-infected patients with TB who are receiving antiretroviral therapy. The document does not cover the diagnosis of TB, diagnosis/treatment of latent TB, or treatment of TB in children. The quality of the evidence was evaluated and the recommendations graded using the approach of the Grading of Recommendations Assessment, Development and Evaluation Working Group.

    Historians of science have yet to study the process by which the oceanographic sciences emerged and became firmly established in Brazil. The main goal of this article is to offer a preliminary analysis of this process by focusing on the contribution of the Instituto Paulista de Oceanografia (Paulista Institute of Oceanography), Brazil's first institution for oceanographic research; it was founded in 1946 and became part of the University of São Paulo in 1951, at which time it was renamed the Instituto Oceanográfico da Universidade de São Paulo (Oceanographic Institute of the University of São Paulo). The analysis centers on the role of three scientists who were on the facility's early research staff: Wladimir Besnard, Ingvar Emilsson, and Marta Vannucci.

    This article is the result of a research on basic training in Astronomy in physics degrees that performed the ENADE 2011 national examination. The objective was to identify whether there are disciplines of Astronomy in these courses, whether are mandatory or optional, its workload and when it is offered. The relationship between astronomers, physics degrees and disciplines of Astronomy was investigated. To perform this research we examined the results of ENADE 2011 and also the census of Brazilian Astronomical Society. As a result it is observed that in only 15% of the courses there is a mandatory subject of Astronomy, and therefore there is a high probability that 85% of physics teachers trained in 2011 have not had any discipline of Astronomy during their graduation. In addition, the data collected in this study shows a low number of members of SAB (Sociedade Astronômica Brasileira) among the surveyed courses. We have verified that the presence of astronomers in a given university does not imply to have a mandatory discipline of Astronomy in physics degrees at the same university. Este artículo es el resultado de una investigación sobre la formación básica en Astronomía en los cursos de Profesorado en Física que hicieron el examen nacional ENADE 2011.

Se investigó también la correlación entre astrónomos, los cursos de licenciatura en Física y las disciplinas de Astronomía. Para realizar esta investigación se utilizaron los datos del ENADE 2011 y también del censo de la Astronomía brasileña. Como resultado, se observó que en solo 15% de los cursos existe una disciplina obligatoria de Astronomía y que existe una grande probabilidad de que 85% de los profesores de Física formados en el año de 2011 no hayan cursado ninguna disciplina de Astronomía durante su

    In this article, we describe the content, sources, and history of the Archivo Histórico de la Facultad de Psicología (the Historical Archive for the History of Psychology) at the Universidad Autónoma de Madrid (UAM, Spain). This archive is the result of the task carried out by some professors of the Faculty of Psychology at UAM for the preservation and increase of sources for a history of psychology in Spain. Collections from the 19th to the 20th century were recovered because of the UAM effort and some other contributions. Most of the sources for a history of psychology in the Spanish context were unknown and nearly lost before Faculty of Psychology's task. Among other projects, UAM archive is acquiring classical texts of psychology by buying facsimiles from different publishing houses and, what is more relevant, they guarantee access to the sources for research purposes.

  18. Exoplanet Transits Registered at the Universidad de Monterrey Observatory. I. HAT-P-12b, HAT-P-13b, HAT-P-16b, HAT-P-23b, and WASP-10b

    Forty transits of the exoplanets HAT-P-12b, HAT-P-13b, HAT-P-16b, HAT-P-23b, and WASP-10b were recorded with the 0.36 m telescope at the Universidad de Monterrey Observatory. The images were captured with a standard Johnson-Cousins Rc and Ic and Sloan z’ filters and processed to obtain individual light curves of the events. These light curves were successfully combined for each system to obtain a resulting one of higher quality, but with a slightly larger time sampling rate. A reduction by a factor of about four in per-point scatter was typically achieved, resulting in combined light curves with a scatter of ∼1 mmag. The noise characteristics of the combined light curves were verified by comparing Allan variance plots of the residuals. The combined light curves for each system, along with radial velocity measurements from the literature when available, were modeled using a Monte Carlo method to obtain the essential parameters that characterize the systems. Our results for all these systems confirm the derived transit parameters (the planet-to-star radius ratio, {R}{{p}}/{R}*; the scaled semimajor axis, a/{R}*; the orbital inclination, i; in some cases the eccentricity, e; and argument of periastron of the orbit, ω), validating the methodology. This technique can be used by small college observatories equipped with modest-sized telescopes to help characterize known extrasolar planet systems. In some instances, the uncertainties of the essential transit parameters are also reduced. For HAT-P-23b, in particular, we derive a planet size 4.5 ± 1.0% smaller. We also derive improved linear periods for each system, useful for scheduling observations.

Este estudio se guio por un diseno tipo encuesta transversal que permitio conocer de manera consistente las conceptuaciones de los estudiantes encuestados acerca de la Ciencia y la Pseudociencia. Ademas, permitio desarrollar inferencias estadisticas relacionadas a la poblacion de estudio, sus conceptuaciones y su inclinacion teorica en torno al Realismo y al Racionalismo cientifico moderados. El instrumento utilizado fue el Cuestionario acerca de las concepciones de la ciencia y la pseudocienca en estudiantes universitarios, Reyes (2015). Este cuestionario fue validado mediante la recopilacion de diversas fuentes de evidencias, entre estas se encuentran las evidencias basadas en el contenido, el proceso de respuesta, la estructura interna y de constructo. Tambien, se calculo el Alfa de Crombach para la escala total y para cada componente y se realizo un analisis de factores que demostro la presencia de seis componentes claramente definidos de acuerdo a lo esperado sobre las caracteristicas originales del instrumento. Las estadisticas utilizadas fueron descriptivas. Participaron 302 alumnos, de las facultades de educacion y ciencias naturales. Se encontro que las conceptuaciones de los estudiantes de ambas facultades se inclinan en un 66.2% a favor con lo establecido en el modelo teorico en torno al Realismo y al Racionalismo cientifico moderados. Sin embargo, aun hay un 33.8% de los estudiantes de ambas facultades que poseen conceptuaciones distintas al modelo teorico propuesto.

    A medical compendium of 'Melleus liquor physicae artis' has survived under the name Alexander Hispanus, possibly a medical scholar of the 13th or early 14th century, in codex Ms 8769 of the Biblioteca nacional in Madrid. But we don't know verifiable facts about Alexander Hispanus. There are more indications, that Alexander was a fictitious person and he never lived. The compendium tells about the maintaining of health as a matter of concern with strong temporal regulations. Therefore a bavarian tract about critical days was enclosed afterwards. This is very interesting, because the tract is dated to 1350 and it's written by a younger hand. Compared with that other parts of the handwriting are dated roughly to the 14th century and are written by an older hand. This tract was now edited (look to the appendix). At the same time a structural analysis of the organisation of knowledge clarified, that the Melleus liquor must be sawn as a well thought-out text altogether. The parts are connected within of three levels of structure: human, medicine, deseases and their recognition. But time is of overriding importance and it's superordinated to these factors of structure. All in all the handwriting monument is certainly written in the 14th century, but it documents medical doctrines of an older age. The late medieval writer probably used much older scripts, that don't exsist any longer. But so they were copied and came down to us fortunately.

    The association between cytomegalovirus and ulcerative colitis has been reported by many authors, but the exact pathogenesis of this relationship remains unclear. We reviewed all ulcerative colitis cases whose diagnosis were made in Hospital dos de Mayo, during period 2000-2005, these cases were evaluated for Cytomegalovirus using inmunohistochemistry, also we described histological features of our cases. CMV was identified in 22.2% of all cases, none of them had been treated with inmunosuppressants previously, histological activity was reported in all positive cases and 42.8% negative cases for CMV; Crypt architectural abnormality was the most often histological finding, and the frequency of ulcerative colitis was 1.5 per year. Our findings are similar to those reported by foreign authors and is consistent with theory which maintains inflammatory changes of UC would help CMV's activation without using inmunosuppressants.

    Four expeditions were made to Coiba National Park between 1996 and 1998 to characterize this part of the poorly known Panamian Pacific polychaete fauna. The samples were collected by SCUBA diving, either by removing 4 kg blocks of dead coral (Pocillopora sp.) or scraping off 25 x 25 cm quadrats of Telesto multiflora or algae (Dyctiota cf. flavellata, Padina cf. durvillaei and another currently unidentified species). This paper deals with the Syllinae from hard substrates. Twenty-two species belonging to six genera of the subfamily Syllinae Grube, 1850 (Syllidae: Polychaeta) are reported. A new species, Syllis castroviejoi, is described. Four species are newly reported for the Eastern Pacific: Syllis beneliahuae (Campoy & Alquézar, 1982), S. botosaneanui (Hartmann-Schröder, 1973), S. corallicola Verrill, 1900 and S. garciai (Campoy, 1982), and, likewise, two species are first reports for the Central American Pacific coast: Branchiosyllis pacifica Rioja, 1941 and Syllis truncata Haswell, 1920. Two species, Syllis magna (Westheide, 1974) and S. pigmentata (Chamberlin, 1919), are newly reported for Panama.

    2002-11-01

    From the beginning of the acoustics program at UACh in 1968, the studies of Acoustic Engineering have been modified and developed according to the vision and human resources of its developers. Three different stages of growth can be seen. When the program began, it was totally aimed at forming skilled professionals in audio and recording. In this way, the professional title given was Sound Engineer. At that time, each applicant was required to have ''good musical hearing,'' which had to be demonstrated through a special musical audition test. The second stage was characterized by the incorporation of acoustics subjects which allowed students, with no musical abilities, to competently work on acoustic engineering activities not related to music. Then, the professional title was changed to Acoustic Engineer. Thus, job opportunities were diversified and access was allowed by all types of students. In the last stage, the study plan was modified as a response to the new vision and requirements of the globalized world in which the environmental component has a great importance. In this work the development of a program that dates from 35 years ago is presented and justified.

    November 22, 1910. During the celebrations of the first one-hundred anniversary of Mexico's Independence War, the solemn reopening of the Universidad Nacional de México takes place. July 22, 1937. Mexico's president general L. Cárdenas and the rector of the Universidad Nacional Autónoma de México, L. Chico Goerne, established an agreement by which the University would extend its function and complete its field of activity through teaching, research, and cultural services. Seventy-five years after the start of the Social Service, its regulations must be reformed to have a better law framework for his important activity. Hence, it is necessary to create a new National System of Social Service or a National Commission of Social Service which, based on general, uniform, equal and fair principles, coordinates, supervises, promotes, and structures students' Social Service for the benefit of the society and the State.

    We describe the Mid-resolution InfRAreD Astronomical Spectrograph (MIRADAS) being developed by the MIRADAS Consortium institutions (including the University of Florida, Universidad de Barcelona, Universidad Complutense de Madrid, Instituto Astrofísica de Canarias, Institut de Física d' Altes Energies, Institut d' Estudis Espacials de Catalunya and Universidad Nacional Autonoma de México) for the Gran Telescopio Canarias. MIRADAS is the most powerful astronomical instrument of its kind ever envisioned. The combination of the collecting area of GTC and the multi-object mid-resolution near-infrared spectra provided by MIRADAS make its capabilities unparalleled for addressing some of the leading scientific challenges of the coming decades, with an observing efficiency more than an order of magnitude greater than current capabilities for 10-meter-class telescopes. We briefly review the science drivers for the instrument, the basic design features, and the current status of the instrument development.

    Any population policy aimed at influencing population growth, or spacial distribution of population must take into consideration social policies, such as education and health, and also demographic policies, such as reduction of mortality. Such policy must be global in its outlook, and must plan for long term results. Economic and social development carries with it the almost irreversible phenomena of demographic transition and urbanization, and its implementation must never violate the fundamental rights and the dignity of the individual citizen. Designing a strategy to achieve certain demographic objectives implies the coordinated action of different sectorial policies, and a very precise knowledge of existing circumstances.

Immunosuppressive protocols have changing with time: from 1968 to 1984 azathioprine + prednisone plus total radiation in some cases; from 1985 to 1998 cyclosporine + azathioprine + prednisone; in 1998 tacrolimus is used for first time; Mofetil micofenolate was available at 2005 and practically has displaced to azathioprine. As far as possible we use some induction therapy. Primary ESRD etiologies were: unknown (74.9%), glomerulonephritis (9.7%) and diabetic nephropathy (4.2%). Recipient's mean age was 29.9 +/- 11.6 years (12-70) and 35 +/- 9.8 years (18-62) in donors. Analysis group for graft and patient survival included 292 transplants (censured for death with functional graft) with a follow-up of 103 months (CI 95%: 99-108). Survival at 1, 5 and 10 years were: 95, 85 and 60% for graft as well as 100, 94 and 90% for patient. In year 2000 we started to perform renal biopsies at transplant (time zero biopsies), those results have been published and at present are a worldwide reference. In September, 2005 laparoscopic donor nephrectomy is initiated, 180 procedures have been done with excellent results. In year 2006, training in renal transplant acquires the endorsement as a Medicine Posgrade recognized by the UNAM School of Medicine. We have participated in 9 national clinical trials and 6 international multicentric ones. Our renal transplant program offers a good choice for patients with low resources with similar results reported in the literature using current immunosuppressive schemes and surgical procedures. Institutional authorities and humanitarian associations support in addition to participation on investigation studies have been of vital importance.

    The essential role of the National Parks is to protect nature, in order to prevent the deterioration and loss of the ecosystem under protection. Very few records about the diversity of arthropods are known from Los Cardones National Park, where three eco-regions are protected: Puna and Monte eco-regions and the High Andean Grassland of the Yungas. Here, we aimed to compare the alpha and beta diversity of arthropods in these eco-regions, and to prove if sites from the same ecoregion, show greater similarity between them in their assemblages, than with sites of the other eco-regions. We also identified arthropod orders with higher species richness, and indicated the families that contribute the most to the registered beta diversity. Three sampling sites were established on each eco-region and the arthropods were sampled using pitfall traps and suction samples. We evaluated the obtained inventory through nonparametric estimators of species richness, and compared diversity among eco-regions through "diversity profiles" and "effective number of species". Beta diversity was assessed by different methods such as the Morisita Index, nonmetric multidimentional scaling analysis, a multiple permutation procedure, and a Similarity Percentage analysis. We recorded 469 spp/morphospecies and recognized three arthropod orders (spiders, dipterans and hymenopterans) that are diverse and abundant in the Park. Besides, the diversity in Los Cardones National Park was found to be high, but it was observed higher in the High Andean Grassland of the Yungas, and lower in the Puna. The inventory obtained was good, reached up to the 81% of the species richness estimated by nonparametric estimators. Each eco-region of the park showed a very particular arthropod community that was tested by a multi-response permutation procedure. The species turnover between eco-regions was high, so that the different environments of the protected area are contributing to the maintenance of the regional diversity of arthropods in the park. The assemblages of arthropods belonging to the same eco-region sites showed greater similarity among themselves than with those of more distant sites. This represents the first attempt for biodiversity studies in these areas, but more evaluations are required to detail on the possible climate change and human impacts in the ecosystem.

    Thirty patients with Burkitt's lymphoma sporadic type are presented. All of these cases fulfilled the histologic criteria of Burkitt's tumor. The age ranged from 2 to 12 years, with a median of 4 years. Fever and chills were the most common symptoms. The abdomen was the site of initial presentation in more than half of these cases. Close to one-third of the patients had involvement of the central nervous system. Fifty percent of the patients presented with lactic dehydrogenase elevation. Uric acid was elevated in close to one-fourth of these patients. The sonogram was the most useful technique in those instances of abdominal presentation. All patients were staged according to Ziegler criteria after an initial surgical diagnostic procedure was performed. None of the patients received radiotherapy to the primary tumor. All were submitted to a chemotherapy program for 12 months. Only 26 fitted the criteria of being evaluable. The duration of remission was from 1 to 144 months, with a median of 18.2 months. The actuarial survival was 84% at 3 years. Most of the responders corresponded to Stages A, B, and AR, while Stages C and D had a high mortality rate with elevated lactic dehydrogenase and uric acid levels.

    Objectives: The purpose of this study was to review the epidemiological aspects of displacement fractures of the acetabulum that had been treated surgically at the National Institute of Traumatology and Orthopedics (INTO). Methods: We retrospectively analyzed 126 acetabulum fractures that had been treated surgically at INTO between March 2006 and November 2008. The following factors were taken into account: age, sex, trauma mechanism, injury classification, time elapsed between trauma and surgery, affected side and associated bone injuries. Results: 76.8% were male; the mean age was 39.6 years. The trauma mechanism was traffic accidents in 59%; the time that elapsed between injury and surgery was on average 16.4 days; 55% of the cases were on the right side; 30% of the patients presented associated fractures. Conclusion: Most of the patients were male, in an economically active age group, and were victims of traffic accidents. Edge and/or posterior column fractures were the most frequent types. Associated injuries were common and most of the fractures operated in our service came to us late. PMID:27022597

    Neotropical puma (Puma concolor) diet is scarcely known, in particular that of mountain dwelling individuals from Northern South America. This is the first study on pumas from the paramo and the first puma diet analysis for Colombia. The puma diet was studied from 2007 to 2009 in the Puracé National Park in the South Colombian Andes. Paramos are unique neotropical high altitude ecosystems which store and regulate water, and are currently threatened by agricultural expansion and climate change. Seven latrines were monitored for three years and scat collected, washed and dried. Items in scat such as hair, bones, claws and others were separated. Hairs were inspected by microscopy and compared to voucher hair museum specimens. Bone fragments, claws and teeth were also compared to museum collections and identified wherever possible. Additionally, six cameras were set along game trails to document puma and potential prey presence in the area. Food items from five species were identified in 60 puma scats; Northern Pudu (Pudu mephistophiles) was the most important prey in their diet. A total of 354 camera trap-nights photographed a male and female puma, Northern pudu and Spectacled bear (Tremarctos ornatus). The main conclusion suggests a strong dependence of puma on the threatened and mysterious Northern Pudu in paramo habitats. This behavior might reflect restricted prey availability in the high Andes mountains of Colombia, and highlights the plasticity in the puma diet. Conservation actions in the paramo should thus, focus on focal wild species, and in particularly those that show a relationship, such as the one evidenced here with the dependence of puma on Northern Pudu. These findings contribute to increase the little known ecology of Andean puma populations and the species as a whole in Colombia. Baseline data on puma prey populations in different ecosystems throughout their range, is critical to understand the regional requirements for survival, and design conservation actions, to follow and evaluate the need for particular protected areas along their geographical gradients.

    The benthic fauna and diel variation in a shallow seagrass bed (Thalassia testudinum) were studied in Playa Mero, Venezuela. Samples of organisms and sediments were taken using PVC cylinders, 5cm in diameter, along a transect perpendicular to the coast. Seagrass cover, shoot density and biomass were estimated. The seagrass cover was homogeneous along the transect. The intermediate zone had the highest number of shoots and of above-ground and rhizome biomass. Composition and abundance of benthic organisms were related with seagrass and sediment characteristics. Sediment organic matter content and organism abundance were highest near the shore Molluscs, polychaetes, oligochaetes and nematodes were the most abundant groups. Species richness was higher in daytime (40 versus 28 at night). Gastropods were the most abundant organisms both at day and night while polychaetes and crustaceans increased during the day, and holoturids were more numerous at night.

    The coral reef fish community was studied in Playa Mero, Morrocoy National Park, after the mass mortality of January, 1996 with a systematic sampling design. Transects and quadrates were used for corals, and a visual census for fishes. The coral community is highly disturbed with extensive areas of dead coral covered by algae, and low coverage and richness of coral species, gorgonians, sponges and briozooans. These factors have generated a relatively homogeneous environment with respect to the fish community, which was dominated by Scaridae and Pomacentridae that represented 75% of fish. Dominant fishes were mainly herbivorous (75.4% of all fish) apparently because of the disturbance that caused the settling of algae.

    The year 1996 had a high pluviosity in Morrocoy National Park (western coastal zone, Venezuela) and low salinity in December 1996 affected the seagrass beds, dominated by Thalassia testudinum. Patches without T. testudinum were observed in localities of the park that used to have very dense populations of this plant. Sampling was done at Las Luisas to determine leaf productivity, turnover rate, short shoot density and relative biomass of plant sections, in order to compare with data obtained in September 1996, previous to the event. Green leaves, roots and rhizomes were the most affected parts. Mean green leaf biomass decreased in January and February 1997 to 5% of the plant's total biomass; mean root biomass decreased in March to 40% and mean rhi zome biomass decreased in February to 30%. The density of the active short shoots decreased to a minimum in February, but in April it reached a value similar to that of September 1996. The density of the inactive short shoots decreased to a minimum in March, and they dissappeared in April, matching the increasing density of the active short shoots between these two months. In February 1997, 56% of the inactive short shoots showed evidence of leaf initiation. In January 1997 the leaf productivity and turnover rate values (2.72 +/- 0.35 g/m2/d and 2.15% leaf DW/d) were similar to the annual mean previously determined from Las Luisas (2.35 +/- 0.72 g/m2/d and 1.96% leaf DW/d). Nevertheless, the values of productivity and turnover rate detected at Las Luisas in April 1997 (4.88 +/- 2.14 g/m2/d and 4.66% leaf DW/d) were higher than those values previously reported for this location. In response to the mortality episode, the leaf productivity and turnover rate of T. testudinum increased and the leaf initiation was activated in the inactive short shoots.

    Many columnar cacti are bat pollinated. It has been suggested that this kind of pollination would be more important in tropical than in temperate regions where flowers are open only one night. Thrichocereus pasacana produces big and resistant white flowers. We analyzed flower characteristics, floral cycle, stigmatic receptivity, nectar production, pollen presence and floral visitors in a T. pasacana population at National Park Los Cardones (Salta, Argentina) in November 1997. Flower features were constant between individuals of the population. Flowers start opening at evening and anthesis time is from 18 to 40 hs. The estigma was receptive throughout the floral cycle. Anther dehiscence occurs with flower opening. Nectar production was highest between 18 to 24 hs. Although T. pasacana are open during the night, floral visitors are diurnal. The most frequent was Xylocopa sp. In the study area, nectarivorous bats were not detected. The morphological features of T. pasacana flowers were similar but bigger compared to other columnar cacti. Anthesis time was also longer while nectar production was lower. T. pasacana pollination at National Park Los Cardones is done by bees.

    We created a model elliptical galaxy through the cold collapse of 100,000 particles using a quadrupolar N-body code. The potential was then freezed and smoothed and 3,472 orbits, selected at random, were investigated using two different methods: 1) Lyapunov exponents; 2) The frequency analysis of Carpintero and Aguilar (1998, MNRAS 298, 1). The results of both methods are compared and the spatial distributions of the different kinds of orbits are presented. Chaotic orbits with only one and with two non-zero Lyapunov exponents are shown to have different spatial distributions, the former behaving in a way more akin to that of regular orbits. This work was supported by grants from the Universidad Nacional de La Plata (UNLP) and from the Consejo Nacional de Investigaciones Científicas y Técnicas de la República Argentina (CONICET).

    Only one prospective study has analysed the relationship between the inflammatory properties of diet and risk of depression thus far. The aim of this study was to assess the association between the dietary inflammatory index (DII) and the incidence of depression. In a cohort study of 15 093 university graduates, participants completed a validated FFQ at baseline and after 10 years of follow-up. The DII was calculated based on the FFQ. Each of the twenty-eight nutrients or foods received a score based on findings from the peer-reviewed literature reporting on the relationships between diet and inflammatory biomarkers (IL-1β, IL-4, IL-6, IL-10, TNF-α and C-reactive protein). Participants were classified as having depression if they reported a new clinical diagnosis of depression by a physician, antidepressant drugs, or both. Multivariable Cox regression models were used to estimate hazard ratios (HR) of depression according to quintiles of the DII. After a median 8·5 years of follow-up, we observed 1051 incident cases of depression. The HR for participants in the highest quintile of DII (strongly pro-inflammatory) was 1·47 (95% CI 1·17, 1·85) compared with those in the bottom quintile, with a significant dose-response relationship (P trend=0·01). In the subgroup analyses, the association between DII and depression was stronger among participants >55 years and among those with cardiometabolic comorbidities (HR 2·70; 95% CI 1·22, 5·97 and HR 1·80; 95% CI 1·27, 2·57, respectively). A pro-inflammatory diet was associated with a significantly higher risk of depression in a Mediterranean population. This association was stronger among older subjects and subjects with cardiometabolic diseases.

    The Mediterranean diet is receiving increasing attention in cardiovascular epidemiology. The association of adherence to the Mediterranean diet with the incidence of hypertension was evaluated among 9,408 men and women enrolled in a dynamic Spanish prospective cohort study during 1999-2005. Dietary intake was assessed at baseline with a validated semiquantitative food frequency questionnaire, and a 9-point Mediterranean diet score was constructed. During a median follow-up period of 4.2 years (range, 1.9-7.9), 501 incident cases of hypertension were identified. After adjustment for major hypertension risk factors and nutritional covariates, adherence to the Mediterranean diet was not associated with hypertension (the hazard ratio was 1.10 (95% confidence interval (CI): 0.81, 1.41) for moderate adherence and 1.12 (95% CI: 0.79, 1.60) for high adherence). However, it was associated with reduced changes in mean levels of systolic blood pressure (moderate adherence, -2.4 mm Hg (95% CI: -4.0, -0.8); high adherence, -3.1 mm Hg (95% CI: -5.4, -0.8)) and diastolic blood pressure (moderate adherence, -1.3 mm Hg (95% CI: -2.5, -0.1); high adherence, -1.9 mm Hg (95% CI: -3.6, -0.1)) after 6 years of follow-up. These results suggest that adhering to a Mediterranean-type diet could contribute to the prevention of age-related changes in blood pressure.

    We describe the operation of an Extensive Air Shower Array located at the campus of the FCFM-BUAP. The array consists of 8 liquid scintillation detectors with a surface of 1 m2 each and a detector spacing of 20 m in a square grid. The array was designed to measure the energy and arrival direction of primary particles that generate extensive air showers (EAS) in the region of 1013 eV - 1016 eV. The angular distribution measured with this array, Cos8(Theta) xSin(Theta), agrees very well with the literature. We also present the measured energies of a number of vertical showers in the range of 5 x1012 eV to 5 x1013 eV.

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.

    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.

    The principles and concepts of the profession of urbanism are presented, and the experience of the University Simon Bolivar in the field is summarized. The perspective of urbanism is that the chaos and poor quality of life in many Latin American metropolitan areas are problems that can be solved through creation of an urban authority that would reconcile urban growth with quality of space and rationality of process. The field of urbanism was dominated for its first century by architects, engineers, and hygienists. In the 1960s, undergraduate programs were designed in town planning, city planning, and urban planning in Great Britain and the US to offer interdisciplinary training, with greater emphasis on the social sciences, mathematical methods of modeling, and distinctness from architecture. The university Simon Bolivar created an urbanism program in 1975, which like other Latin American programs gave somewhat greater emphasis to training in spatial design than did the US and British programs. The program has continued to be based on a systemic focus and the union of design and management in urban planning practice. The object of study has been redefined to encompass not just the city but the general environment. The program in its first 20 years has had internal problems such as the tendency of some professors to over-emphasize their own disciplines and insufficient training in management techniques, and external problems such as the negative societal image of urbanism and urbanization. Reinforcement of the computer capabilities and faculty should enable the program to meet future challenges.

    BACKGROUND Some research indicates that physicians do not dominate the expected dermatological content for the proper exercise of the profession. This fact compromises their diagnostic and therapeutic performance, generating unnecessary costs. OBJECTIVE The aim of this study was to evaluate the relevance of Dermatology and the knowledge acquired in the specialty during the undergraduate course in clinical practice of graduates at the State University of Campinas Medical School (FCM/UNICAMP). METHOD A questionnaire with 22 closed questions and two open ones was electronically sent to physicians who had graduated more than 10 years ago and others for less than 10 years. In the first group, physicians were trained by the same curriculum and in the second group there were subjects trained by the old and the new curriculum. RESULTS Of the 126 respondents, 83% had completed a specialization course. Among all, 82% did not study dermatology after graduation. The majority considered that Dermatology has high relevance in clinical practice, regardless of the group. There was a statistically significant difference between non-dermatologist doctors graduated for more than 10 years and those graduated for less than 10 years regarding confidence about lesion diagnosis, diagnostic investigation and treatment of skin diseases. Physicians who have graduated for a longer time feel more insecure in relation to patients with dermatoses. Concerning contributions offered by graduation program completion they prioritized outpatient care, ability to diagnose, knowledge of pathology, research and knowledge of lesions. CONCLUSION This study has shown that Dermatology is relevant in medical practice and more recent graduates from the FCM/UNICAMP feel less insecure when treating a patient with dermatoses.

    Graduate students in volcanology need a wide variety of scientific and cultural perspectives to become proficient at understanding volcanoes and their moods. With this in mind, a six-university consortium in Earth hazards organized an advanced graduate class on supereruptions during the 2006 winter semester. The Earth Hazards (EHaz) university consortium consists of Michigan Technological University (Houghton, Mich.), the University at Buffalo (N.Y.), McGill University (Montreal, Quebec, Canada), the University of Waterloo (Waterloo, Ontario, Canada), Universidad Nacional Autónoma de México (UNAM; Mexico City), and the Universidad de Colima (Colima, Mexico), and it is funded by the U.S. Department of Education and couterpart agencies in Mexico and Canada as part of the North American Free Trade Agreement.

    Agromyza Fallén (Diptera, Agromyzidae) is a genus of leaf mining flies, including species with high economic importance. The knowledge of this genus is very poor in the neotropics, with 12 known species, only six of them recorded from Brazil. This paper describes two new Agromyza species from "Cerrado" and "Pantanal" biomes and records three other species represented only by females that could not be identified to species level. We also present a taxonomic key to segregate the 14 Neotropical species. The specimens were collected in Mato Grosso and Mato Grosso do Sul states and are deposited at Museu de Zoologia, Universidade de São Paulo (São Paulo, Brazil) and Museu Nacional, Universidade Federal do Rio de Janeiro (Rio de Janeiro, Brazil) collections. The adults were photographed and the male terminalia were dissected and illustrated.

    A survey was carried out to determine the perception and knowledge about biotechnology and genetically modified organisms (GMOs) in a sample (n=750) of university students from three public universities in Costa Rica: Universidad de Costa Rica, Universidad Nacional and Instituto Tecnológico de Costa Rica. The study revealed that 88% of the students showed a satisfactory level of knowledge about modem biotechnology and 79% of them reported a favorable opinion and good acceptance of this technology. Students would accept some risks associated to biotechnology if it represents an improvement to the competitiveness of Costa Rica. Some differences were detected in the opinions from students of the three universities that can be associated to the area of study. Students from social disciplines showed a higher percentage of negative acceptances to biotechnology and GMOs when their opinions were compared with those of students from life sciences and technologies.

    The Institute of Astronomy at the Universidad Nacional Autonoma de México have developed and tested a CCD controller based on Texas Instruments Digital Signal Processor (DSP) TMS30C31@50MHz. Images are temporally stored in a 2MB static RAM attached to the DSP and transferred to the host computer running under Linux. Both tasks, acquisition and timing, are programmable so it can be conditioned to control any bidimensional detector. Analog voltage for bias, offsets and gains are fully programmable also. The system has been tested on an infrared Hawaii detector and fast Marconi 80x80 pixels CCD.

    The tectonic setting, produced by the interaction between the Cocos and North American plates, follows complex geometries along the Pacific coast. Previous studies in central Mexico showed that the slab dips nearly horizontally before steeply subducting into the continental mantle; in contrast, in southern Mexico, the slabs dips under the continental plate at a constant angle. Receiver functions from four seismic networks: GECO (Geometry of Cocos), SSN (Servicio Sismológico Nacional), OxNet (Oaxaca Network) and UV (Universidad Veracruzana) are used to study the crustal structure underneath the stations, and image the subducting Cocos plate in order to define the geometry and the transition angle in central-southern Mexico.

    "Biomoléculas" is a software that deals with topics such as the digestion, cellular metabolism and excretion of nutrients. It is a pleasant, simple and didactic guide, made by and for students. In this program, each biomolecule (carbohydrates, lipids and proteins) is accompanied until its degradation and assimilation by crossing and interrelating the different metabolic channels to finally show the destination of the different metabolites formed and the way in which these are excreted. It is used at present as a teaching-learning process tool by the chair of Physiology and Biophysics at the Facultad de Ingeniería - Universidad Nacional de Entre Ríos.

    Mesenteric cysts are rare abdominal tumors. About 60% of these cysts occurs before 5 years of age and can be located anywhere in the gastrointestinal tract, but are most often found in the small bowel mesentery. The clinical presentation depends on the location and size of the cyst and many cases are asymptomatic and are diagnosed incidentally. The most common symptoms are abdominal pain, bloating, abdominal mass, nausea, vomiting, constipation, diarrhea, weight loss, fever and peritonitis. Complications include torsion, infarction, volvulus formation, perforation, infection, anemia, intracystic hemorrhage, intestinal obstruction and obstructive uropathy. They are typically treated by simple excision, marsupialization or segmental bowel resection and have excellent long-term prognosis.

    The AMS system at CNA has been the first 1MV compact AMS system designed and manufactured by HVE. In this paper we present the experimental set-up for (129)I measurements in this facility. Charge state +3 has been selected at high-energy side and an optimum stripper pressure of 6×10(-3)mbar of argon (mass thickness of about 0.15μgcm(-2)) has been reached to obtain lowest blank values ((129)I/(127)I≅3×10(-13)). The measurements of the reference materials provided by the IAEA have demonstrated the viability of this facility to make routine measurements of (129)I at environmental levels. This blank value obtained is enough for the measurement of most environmental samples and comparable with other reported backgrounds obtained in facilities working at higher energies and higher charge states.

    The diagnosis and treatment of thyroid disease has significantly changed with time. With the aim of analysing changes in thyroid surgery in our institution, a representative sample of patients from the first three years in four decades (1960-1992) were comparatively analysed. In the sixties, the diagnosis of thyroid cancer was made during surgery; by contrast, this diagnosis was correctly done by fine needle aspiration (FNA) in most patients of the last decade. Thyroid lobectomy, infrequently used in the treatment of differentiated thyroid carcinoma in earlier times, has now been abandoned and currently most patients undergo total or near-total thyroidectomy. Complications such as hypoparathyroidism and recurrent laryngeal nerve paralysis have importantly decreased with time and were not seen in the last decade. A trend toward an earlier diagnosis of thyroid carcinoma was also observed. In summary, the number of thyroidectomies for benign diseases has been importantly reduced by the use of FNA with the proportional increment of surgery for malignant disease.

    The purpose of this retrospective study was to study the incidence of idiopathic and secondary forms of membranous nephropathy in our institution, its clinical course and progression to chronic renal failure, and the risk factors associated with it. Two hundred fourteen (16%) of the 1,287 renal biopsies obtained between 1962 and 1988 were primary glomerular diseases and 28 of this 214 (13%) were idiopathic membranous nephropathy. On the other hand 59 of 1,287 biopsies were membranous nephropathy of whom 28 were idiopathic, 27 secondary to systemic lupus erythematosus, 2 due to drugs, one associated with rheumatoid arthritis, and one more with breast cancer. The clinical picture was: nephrotic syndrome in 84%, hypertension in 15%, non-nephrotic proteinuria in 14%, chronic renal failure in 8.4%, and renal vein thrombosis in 6.3%. In the idiopathic group 75% of the patients were male while in the lupus group 85% were female. For the analysis of progression to chronic renal failure we excluded 5 patients with renal failure when the biopsy was taken, 2 because the nephropathy was due to drugs, one associated with breast cancer, and nine were within the first year of follow-up. Thus, for this analysis the group consisted of 22 patients with idiopathic form and 20 with systemic lupus erythematosus. The idiopathic and lupus groups were similar except for a lower serum albumin in the former. The progression to renal failure was seen in 9 patients: six in the idiopathic group and the other 3 in the lupus group; this difference was not significant.(ABSTRACT TRUNCATED AT 250 WORDS)

    2000-12-01

    This paper is the second part of a base line study carried out in the coastal region near a marine service station located in Morrocoy National Park, Venezuela. Results from a physical and chemical characterization of the water and sediments of four sites located around the service station are presented. The physical and chemical factors measured in water included: temperature, salinity, specific conductance, dissolved oxygen, saturation percentage of dissolved oxygen, pH, total suspended solids, transparency, oil and grease, total residual petroleum hydrocarbon, vanadium and lead, total coliform bacteria, and the presence of coliform bacteria. The factors measured in sediments include: granulometry, organic material, total carbonates, vanadium, lead, oil and grease, and total hydrocarbons. In addition, the amount of vanadium and lead in sample tissue from three species which are abundant and widely distributed in each site was measured in order to evaluate the potential of these species as bio-indicators. The water in the area where this study was conducted is shallow, warm, and thermally homogeneous, with high salinity and normal pH and dissolved oxygen, and supersaturated with oxygen in certain hours in sites adjacent to abundant underwater vegetation. The water is moderately turbid with a tendency towards less dissolved oxygen with increased depth. The estimated values of NMP/100 ml of the coliform fecal organisms is within legal limits even though the total number of water coliforms measured in Site 2 was ten times higher than in Site 1. This increase is associated with the proximity of Site 2 to an outflow of pre-treated sewage. The values of TRPH in the water collected from each site were low and very close to the detection limit (0.8/ml). Vanadium was not found, while lead was detected in 11 of the 12 samples. Compared to the values measured for Site 1, which was the local reference, only one sample had a concentration of three times the maximum baseline. The amount of lead found in all analyzed samples was acceptable, according to the standards set by the State of Washington (maximum value: 292 mg/kg), while the concentration of lead in the sediments around the supply dock were 1.5 to 3.4 times greater than the Dutch norm. It can be concluded that there is no evidence of an accumulation of Va or Pb in the species selected as bioindicators. An observation program is proposed in which variables similar to those measured for this characterization will be studied with some modifications. A more intense sampling of some variables is recommended (lead in water and sediments, total coliform and fecal matter in consecutive samples and in days following a high concentration of visitors) as is the elimination or minimization of other variables.

    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.

The button batteries are the most common, in which case is important early diagnosis and removal. The cylindrical battery ingestion is very rare, are typically alkaline manganese or nickel-cadmium (rechargeable) and when ingested they can cause toxic and corrosive damage. Such damage may occur as a result of the effect of acid gastric contents sustained over a period of days or weeks. We report the case of a patient who accidentally ingested a cylindrical battery, which was removed from the stomach endoscopically without complications.

    The impact of Mexican gastrointestinal research worldwide is limited and the outcome of the best research papers awarded by the Asociación Mexicana de Gastroenterología (AMG) is unknown. The objective of this study was to analyze the publication pattern of the research work, awarded by the AMG and their impact in international journals. The abstracts accepted for the annual meeting of the AMG from 1998 to 2006 were reviewed. Those presented in a plenary session or awarded were included. Their abstracts were searched in electronic databases. When not found, the main author was contacted by e-mail. In those papers published in a journal with an impact factor, the times it was cited were assessed. 35 abstracts were identified, mainly in gastroenterology (57.1%) and hepatology (34.3). Only in 5.7% (n=2) some of the authors were members of the governing board of AMG. The awarded institutions were Instituto Nacional de Ciencias Médicas y Nutrición Salvador Zubirán (48.6%), Universities (Universidad Autónoma de Nuevo León, Universidad Nacional Autónoma de México and the Benemérita Universidad Autónoma de Puebla) (31.4%), Instituto Mexicano del Seguro Social (8.6%), Fundación Clínica Médica Sur (5.7%), Hospital Juárez (2.9%), Private hospital (2.9%). Most of the papers were published within a year (73.7%). Only 2 papers had more than 10 citations in another international journal with impact factor, with a median for all paper of 5 citations (0-45). Considering all institutions, the rate of publication is 48%. Only half of the awarded works were published and mainly in journals of local distribution. The impact of these studies worldwide is limited.

    The Mid-resolution InfRAreD Astronomical Spectrograph (MIRADAS, a near-infrared multi-object echelle spectrograph operating at spectral resolution R=20,000 over the 1-2.5μm bandpass) was selected in 2010 by the Gran Telescopio Canarias (GTC) partnership as the next-generation near-infrared spectrograph for the world's largest optical/infrared telescope, and is being developed by an international consortium. The MIRADAS consortium includes the University of Florida, Universidad de Barcelona, Universidad Complutense de Madrid, Instituto de Astrofísica de Canarias, Institut de Física d'Altes Energies, Institut d'Estudis Espacials de Catalunya and Universidad Nacional Autónoma de México. This paper shows an overview of the MIRADAS control software, which follows the standards defined by the telescope to permit the integration of this software on the GTC Control System (GCS). The MIRADAS Control System is based on a distributed architecture according to a component model where every subsystem is selfcontained. The GCS is a distributed environment written in object oriented C++, which runs components in different computers, using CORBA middleware for communications. Each MIRADAS observing mode, including engineering, monitoring and calibration modes, will have its own predefined sequence, which are executed in the GCS Sequencer. These sequences will have the ability of communicating with other telescope subsystems.

  1. Social identity, passion and well-being in university students, the mediating effect of passion.

    Research on positive emotions associated with the performance of an activity, such as work or study, has increased exponentially in recent years. Passion is understood as an attitude and intense emotion in the performance of an activity, and it has shown both positive and negative consequences for well-being. A link between social identity and positive emotions through social category membership has been described. The aim of this work is to study the relationship between social identity, the dimensions of passion and the positive impact on university responses. A quasi-experimental design was used on a sample of 266 university students from different Spanish universities (Universidad Nacional de Educación a Distancia, Universidad Miguel Hernández and Universidad de Alicante). Descriptive analyzes were performed on the study's variables using SPSS 18. Structural equation modeling was carried out with AMOS 18 and the mediational analysis with MODMED macro developed by Preacher, Rucker, and Hayes (2007). The results show that the identity of the studies had an indirect effect on positive responses mediated by passion for the studies (RMSEA = .07; CFI = .97; NFI = .96; TLI = .92). It is observed that the harmonious and obsessive dimensions of passion differ in the mediating effect on happiness and satisfaction with studies. Practical and theoretical implications for well-being are discussed.

    Introducción: el síndrome metabólico es un conjunto de alteraciones metabólicas que incrementan el riesgo de desarrollar diabetes tipo 2 y enfermedades cardiovasculares. Existen varios criterios para su diagnóstico, entre ellos los más utilizados son el de la Federación Internacional de Diabetes (IDF) y el del Panel de Tratamiento de Adultos III (ATP III). Un tratamiento oportuno puede evitar las complicaciones asociadas y mejorar la calidad y esperanza de vida del paciente, que debe ser enfocado a realizar modificaciones en el estilo de vida, como una alimentación saludable y actividad física regular. Objetivo: determinar la prevalencia de síndrome metabólico según los criterios de diagnóstico de la Federación Internacional de Diabetes (IDF) y del Panel de Tratamiento de Adultos III (ATP III). Metodología: es un estudio de corte transversal en el cual participaron 128 personas (55 mujeres y 73 hombres) de entre 18 y 75 años de edad, a quienes se les realizó una historia nutricional, medidas antropométricas y exámenes bioquímicos. Resultados: la prevalencia de exceso de peso fue del 63% (sobrepeso 48% y obesidad 15%). La prevalencia de síndrome metabólico según IDF fue 15,6% y según ATPIII 14,8%. Conclusiones: en el personal evaluado, es evidente la alta prevalencia de exceso de peso y síndrome metabólico, por lo que es prioritario trabajar en la implementación de medidas preventivas para detener su progresión y el desarrollo de complicaciones cardiometabólicas.

    Ultimately, medical education is oriented world wide towards the promotion and improvement of people's health and the promotion of welfare, along with other organisations. The development of science, technology and instructional resources, the concerns of the community and nations about health matters and their health care policies, require a new approach towards medical education. Universities must be aware of these new demands, that must be taken into account in medical education. New medical curricula should consider the new scenarios in which the process of health and disease takes place and the new participants in such process, the need for technological offices with trained and committed personnel devoted to its design and the need to be permanently evaluated.

    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.

    The Prenatal Diagnosis Program of the Medical Genetic Unit of University of Zulia has the following objectives: Identification of Genetic Risk Factors (GRF) in those couples who attend to the Prenatal Genetic Clinic, application of different prenatal diagnostic procedures (PDP), and providing adequate genetic counseling. The goal of this paper is to show preliminary results obtained between January 1993 and December 1996. Three hundred and twenty one pregnant women were analyzed by determining the GRF and taking into account the genetic clinical history. The GRF analyzed were: Advanced maternal age (AMA), congenital malformation history (CMH), previous child with chromosomic anomalies (PCCA), defects of neural tube history (DNTH), congenital heart disease history (CHDH), any parent carrier of chromosomic anomaly (PCA), habitual abortion (HA), abnormal fetal echography (AFE), altered maternal serum levels of alpha-feto-protein (AMSAFP) and OTHERS: exposure to teratogenic agents, history of Mendelian diseases, maternal systemic diseases and anxiety in the mother or in her partner. The PDP was designed according to the GRF, which included fetal echography (FE), fetal echocardiography (FEc), amniocentesis (AMN), chordocentesis (CCT) and AMSAFP. Results showed that 58.4% of the expectant mothers asked for counseling during the 2nd trimester, 70% of the total showed only one GRF, and AMA was the most frequent GRF found (40.3%), followed by PCCA, AFE, CHDH, HA, DNTH, PCA, and OTHERS in that order. The specific PDP applied to the identified GRF allowed a health evaluation of the fetus. The GRF identification gave the opportunity of establishing a Prenatal Diagnostic Program producing a response to the couple's needs and showed the utility of an integral and multidisciplinary management directed to any expecting mother in order to identify any high GRF.

    Listeria monocytogenes is Gram-positive facultative intracellular pathogen often foodborne and found elsewhere. It is an uncommon cause of illness in the general population. However, it is an important cause of severe infection in neonates, pregnant women, elderly and immunosuppressed patients. Listeriosis has unique preference for pregnant women. Maternal listeriosis is a diagnostic challenge, and intrauterine infection can lead to severe complications such as amnionitis, preterm labor, spontaneous abortion, stillbirth and neonatal sepsis. From 2001 to 2005, 16 patients with L. monocytogenes were identified in this hospital; four (25%) were pregnant women. Clinical and laboratory findings are described. There were 3 preterm deliveries and 1 spontaneous second trimester abortion. Three women with listeriosis had no predisposing factors other than pregnancy. One patient was on immunosupressive drugs for ulcerative colitis. Fever was the most common symptom. Infected neonates were most commonly diagnosed with early-onset listeriosis (two cases) or fetal demise (one case). Pregnancy can be the only risk factor for listeriosis. Listeriosis should be considered during the evaluation of febrile syndrome in pregnancy as this condition can be the only risk factor. Blood and amniotic fluid cultures are useful diagnostic tests. Perinatal complications remains high.

    Background The role of alcohol as a risk factor for motor vehicle crashes is long known. Yet, reports on the prevalence of drinking and driving suggest values between 20%–30% when the adult driving population is interviewed. We wondered whether these values hold true among European educated citizens and whether there are any significant differences in prevalence by age, gender, type of profession and other lifestyle indicators. Methods Cross-sectional analyses of baseline data from a cohort of university graduates in Spain (SUN study). Answered questionnaires contained items on current drinking and driving practices, together with data on socio-demographic characteristics and lifestyle habits. Chi square, Fisher test, and multivariate logistic regression were used to investigate the impact of several variables on drinking and driving practices. Analyses were stratified by gender. Results Almost 30% of the participants reported "sometimes" drinking and driving. This percent increased to 47% when "almost never" was also included as a positive answer to the drinking and driving practice question. These percentages varied significantly by gender, with up to 64% of men reporting "sometimes" or "almost never" vs. 36% of women doing so. Drinking and driving practices also differed by overall alcohol consumption habits, smoking, use of safety belts, and notably, type of profession. Conclusion Our findings are amongst the first on the high prevalence of drinking and driving among Spanish. Particularly worrisome is the fact that health professionals reported this habit even at higher rates. Multidisciplinary interventions (e.g., legal, educational, economic) are needed to reduce this serious health risk. PMID:17430581

    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.

    Antecedentes: La colecistectomía por video-laparoscópica es considerada como el gold-standard del tratamiento de la colecistolitiasis. No obstante, en la literatura internacional sigue teniendo presencia las incisiones pequeñas adaptadas como procedimiento alternativo. Objetivos: El objetivo de este estudio es evaluar los resultados obtenidos con la video-laparoscopia (CVL) y las incisiones pequeñas adaptadas (IPA) en el tratamiento de la colecistolitiasis. Diseño: Prospectivo y comparativo protocolizado. Lugar de aplicación: Servicio de Cirugía General “Pablo Luis Mirizzi” del Hospital Nacional de Clínicas. Material y Métodos: Entre enero del 1994 y diciembre del 2011, hemos tratado quirúrgicamente 3822 pacientes con colélitiasis. En 1735 pacientes se práctico una CVL y en 2087 por IPA, configurando dos grupos, que en lo relacionado a la edad, sexo, operaciones previas y diagnóstico preoperatorio constituyen dos grupos comparables. Resultados: Ninguno de los procedimientos tuvo mortalidad. 115 casos (6,62%) fueron convertidos a cirugía abierta en la CVL. Las complicaciones postoperatorias quirúrgicas fueron del 2,40 % para la CVL y del 6,37 % para las IPA. Las causas de bilirragias fueron superiores y de mayor gravedad en la CVL, cuya incidencia fue del 0,55 % en contraposición del 0,23 % de los operados por IPA. Conclusiones: Sin duda en manos experimentadas la CVL constituye el procedimiento de elección o gold standard en el tratamiento de la colecistolitiasis. No obstante, sobretodo en ambientes o regiones con restricciones presupuestarias las IPA representa una excelente gold estándar alternativo, por ser un procedimiento seguro, muy económico y complejidad razonable con menor índice de lesiones quirúrgicas graves.

    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)

    Pelvic ring fractures are associated with high rates of mortality and thus can provide key information about circumstances surrounding death. These injuries can be particularly informative in skeletonized remains, yet difficult to diagnose and interpret. This study adapted a clinical system of classifying pelvic ring fractures according to their resultant degree of pelvic stability for application to gross human skeletal remains. The modified Tile criteria were applied to the skeletal remains of 22 individuals from the Cleveland Museum of Natural History and Universidad Nacional Autónoma de México that displayed evidence of pelvic injury. Because these categories are tied directly to clinical assessments concerning the severity and treatment of injuries, this approach can aid in the identification of manner and cause of death, as well as interpretations of possible mechanisms of injury, such as those typical in car-to-pedestrian and motor vehicle accidents.

    Nine anostracan biogeographical regions are defined for North America: Appalachia/Ozark, Southwest Arid, Great Plains, Coastal Plain, Neotropical, California, Cold Deserts, Beringia/Canadian Shield, and Transmontane. These regions are quantitatively defined using species distributions compared through Jaccard's Coefficient of Community Similarity, and qualitatively defined using climate data, following the ecoregions protocol of the US Environmental Protection Agency for North America and the Universidad Nacional Autónoma de México for Mexico. Community assemblages are quantified using Fager's Index of Recurring Species Groups. The average Fager's Index for each bioregion, as well as the percentage of taxa co-occurring, generally decreases with the length of time the region has been available for colonisation. The strong Fager's Index/colonisation time availability relationship suggests that the Monopolization Hypothesis of De Meester et al. may function at larger landscape scales.

    The conventional educational environment imposes barriers to education for people with disabilities, limiting their rights, which is a non-discriminative education. In turn, hampers their access to other rights and creates huge obstacles to realize their potential and participate effectively in their communities. In this sense Assistive Technology provides alternative solutions, in order to compensate for a lost or diminished ability. Thus the necessary assistance is provided to perform tasks, including those related to education, improving the inclusion. In this paper some researches had been made in the Gabinete de TecnologiaMedica, in the Facultad de Ingenieria of the Universidad Nacional de San Juan in order to solve this problem. The researchers are classified by type of disability; sensory (visual and auditory) or motor. They have been designed, developed and experienced through various prototypes that have given satisfactory results. It had been published in national and international congresses of high relevance.

    Cerón Loayza, María Luisa; Bravo Cabrejos, Jorge Aurelio

    2013-03-01

    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.

    The aim of this research study was to describe the perceived level of food security in the households of the city of Santa Fe, Argentina, in 2011. A descriptive, cross-sectional study was performed, incorporating 592 homes included in the Panel of Households of the Social Observatory of the Universidad Nacional del Litoral. Households were characterized sociodemographically and classified according to the level of food security by applying the Latin American and Caribbean Food Security Scale. Association with sociodemographical factors was determined by odds ratios and logistic regression. It was found that 31.5% of households in Santa Fe show food insecurity: 21.7% is mild, 7.4% is moderate and 2.4% is severe, and insecurity is greater when children live in the household. Food insecurity is positively associated with lack of health coverage, lack of economic activity, inability to save, incomplete secondary level education and four or more people living in the household.

    In order to evaluate the frequency of depressive symptomatology (DS) and alcohol-related problems (ARP) during the academic training of medical students from Universidad Nacional Mayor de San Marcos, a cross-sectional study was conducted among students from first to sixth year of career. The Zung Self-Rating depression scale was used to evaluate DS and the CAGE questionnaire to evaluate ARP. 23.3% of participants had DS, and 7.3% had ARP. We found that the frequency of DS and ARP was higher among students in the first years of career. We recommend it is necessary to take action in the prevention and detection of these disorders from the first years of training of medical students.

    TAOS II is a next generation occultation survey with the goal of measuring the size distribution of the small objects (diameters between 0.5 and 30 km) in the Kuiper Belt. The project is a collaboration between the Academia Sinica Institute of Astronomy and Astrophysics, the Universidad Nacional Autonoma de Mexico, and the Harvard-Smithsonian Center for Astrophysics, The survey will operate three 1.3 m telescopes at San Pedro Martir Observatory in Baja California, Mexico. Each telescope will be equipped with a custom camera comprising a focal plane array of CMOS imagers. Each camera will be capable of reading out image data from 10,000 stars at a cadence of 20 Hz. All telescopes will monitor the same set of stars simultaneously to search for coincident occultation events while minimizing the false positive rate. This poster describes the project and reports on the progress of the development of the survey infrastructure.

    Pictures of facial expressions of emotion are used in a wide range of experiments. The last decade has seen an increase in the number of studies presenting local sets of emotion stimuli. However, only a few existing sets contain pictures of Latin Americans, despite the growing attention emotion research is receiving in this region. Here we present the development and validation of the Universidad Nacional de Cordoba, Expresiones de Emociones Faciales (UNCEEF), a Facial Action Coding System (FACS)-verified set of pictures of Argentineans expressing the six basic emotions, plus neutral expressions. FACS scores, recognition rates, Hu scores, and discrimination indices are reported. Evidence of convergent validity was obtained using the Pictures of Facial Affect in an Argentine sample. However, recognition accuracy was greater for UNCEEF. The importance of local sets of emotion pictures is discussed.

    The aim of the project is to have a multipurpose facility which will enable us to show the techno-economic viability of the irradiation process applied to regional products, important from the economic point of view. The topics will fundamentally be connected with regional themes such as food preservation and the modification of polymer structures. This project will make it possible to carry out basic and applied studies related to radiation chemistry, dosimetry and engineering irradiation processes. The facility will operate in the Universidad Nacional del Sur (UNS) with a maximum activity of 18.5 PBq of Co-60. The viability and design of the irradiation facility is supported by the Government of the Buenos Aires Province since it is interested in the socio-economic benefit of this technology at the regional level.

    The challenge in achieving an ideal state of justice is that each "proof" has the highest degree of reliability. This is the main responsibility of the forensic scientist. Up to now, criminal investigations in Mexico have been supported by forensic work from a wide variety of disciplinary backgrounds that give testimony in a particular area, even though they may have become forensic witnesses in a complementary and experiential manner. In January 2013, the Universidad Nacional Autónoma de México (UNAM) approved the "Forensic Science" undergraduate program that, in collaboration with various academic entities and government institutions, will develop forensic scientists trained in science, law, and criminology. This is focused on contributing to the national demand that the justice system has more elements to procure and administer justice in dealing with crime.

    2007-11-01

    The challenges in Bioengineering are not only the application of engineering knowledge to the measurement of physiological variables, but also the simulation of biological systems. Experience has shown that the physiology of the respiratory system involves a set of concepts that cannot be effectively taught without the help of a group of didactic tools that contribute to the measurement of characteristic specific variables and to the simulation of the system itself. This article describes a series of tools designed to optimize the teaching of the respiratory system, including the use of spirometers and software developed entirely by undergraduate Bioengineering students from Universidad Nacional de Entre Rios (UNER). The impact these resources have caused on the understanding of the topic and how each of them has facilitated the interpretation of the concepts by the students is also discussed.

    In this article we discuss the role that medical schools play in the creation of a particular profile of health professionals. To this end, we analyze the impact of two field experiences carried out in 2006 and 2009 with students in the Epidemiology course of the Faculty of Medical Sciences in the Universidad Nacional de La Plata (in the province of Buenos Aires, Argentina). Using individual semistructured questionnaires applied to students as well as focus group strategies, the study sought to obtain information about the ideas and representations of the students before and after these educational experiences. The ability of students to reconsider the explicative models of the health-disease-care process and the weight of social problems in the phenomena of sickness and health is highlighted as one of the study's primary results.

    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.

    The aim of our study is to calculate the dielectric function for a system formed with a graphene layer doped with barium titanate. Density functional theory, within the local density approximation, plane-waves and pseudopotentials scheme as implemented in Quantum Espresso suite of programs was used. We considered 128 carbon atoms with a barium titanate cluster of 11 molecules as unit cell with periodic conditions. The geometry optimization is achieved. Optimization of structural configuration is performed by relaxation of all atomic positions to minimize their total energies. Band structure, density of states and linear optical response (the imaginary part of dielectric tensor) were calculated.

Actualmente há uma grande dificuldade na integração dos doentes no domicílio ou em estruturas de retaguarda. Pretende-se comparar o impacto da referenciação para a Rede Nacional de Cuidados Continuados Integrados versus alta para domicílio, no tempo de internamento dos doentes com Acidente Vascular Cerebral, entre 2010 e 2011.Material e Métodos: Estudo retrospectivo envolvendo os doentes internados na Neurologia A e Unidade de Acidente Vascular Cerebral dos Hospitais da Universidade de Coimbra, naquele anos. Analisaram-se 1 209 processos, incluídos 819, caracterizados demograficamente, tempo de internamento, Score de Rankin modificado e destino pós-alta. Compararam-se os dados, relativamente ao tempo de internamento dos doentes com Acidente Vascular Cerebral, referenciados para a Rede Nacional de Cuidados Continuados Integrados e os com alta para domicílio, atendendo ao Score de Rankin final.Resultados: Em 2011, aumentaram os doentes referenciados para a Rede Nacional de Cuidados Continuados Integrados, 23,5% comparativamente 21,4%. Em 2011 o tempo de internamento, para um mesmo Score de Rankin, da população referenciada manteve-se superior: para um Rankin de 1: 11 dias para domicílio, 26 dias para os doentes referenciados; para um Rankin de 2: 13 dias para domicílio, 29 dias para a rede; para Rankin de 3: 13 dias para domicílio, 23 dias para referenciados; para um Rankin de 4: 17 dias para domicílio, 33 dias para Rede; e para um Rankin de 5: 27 dias para domicílio, 39 dias para Rede. Comparando com os tempos de internamento da população com alta para domicílio, estima-se que tenha representado mais 1 718 dias de internamento, em 2010 e1 198 dias, em 2011.Conclusão: A Rede Nacional de Cuidados Continuados Integrados é incapaz de responder às necessidades actuais

    This work has two main purposes: (i) introducing the basic concepts of molecular dynamics analysis to material scientists and engineers, and (ii) providing a better understanding of instrumented indentation measurements, presenting an example of nanoindentation and scratch test simulations. To reach these purposes, three-dimensional molecular dynamics (MD) simulations of nanoindentation and scratch test technique were carried out for generic thin films that present BCC crystalline structures. Structures were oriented in the plane (100) and placed on FCC diamond substrates. A pair wise potential was employed to simulate the interaction between atoms of each layer and a repulsive radial potential was used to represent a spherical tip indenting the sample. Mechanical properties of this generic material were obtained by varying the indentation depth and dissociation energy. The load-unload curves and coefficient of friction were found for each test; on the other hand, dissociation energy was varied showing a better mechanical response for films that present grater dissociation energy. Structural change evolution was observed presenting vacancies and slips as the depth was varied.

    2011-12-01

    The Servicio Sismológico Nacional (SSN) is Mexico's official organism in charge of the observation of seismicity in the country. Operated by the Universidad Nacional Autonoma de Mexico, it counts with 32 broadband stations deployed throughout the country. The coverage includes most of the geologic provinces of the territory, which vary widely in their geologic characteristics. The availability of records from teleseisms at those stations makes feasible to obtain sound and homogeneous estimates of the structure of the crust in the Mexican territory through the analysis of receiver functions (RF). In this work we present the results of the analysis of RF obtained from events registered from 1998 to 2009 in the 32 stations of the SSN. The RF technique, which uses converted phases at major velocity discontinuities, is a well established technique to infer the velocity contrasts and thickness of the underlying crust. Using this method we were able to infer the depth of the Moho, a major intracrustal discontinuity and in some cases the depth to the base of the subducting plate. We present maps of crustal thickness in Mexico, which varies between about 29 km in the Yucatan peninsula to more than 40 km in central Mexico. Poisson's coefficient varies between 0.19 and 0.30. The position of the descending slab shows a large variation in the subduction angle (from about 6° in the SE margin of the Pacific coast to about 60° in the NW ) as has been found from other techniques.

    The case of a patient with dystrophic epidermolysis bullosa treated with radiosterilised amniotic membranes is presented. The disorder is a congenital disease characterised by a poor desmosomal junction in the keratinocyte membrane. After proper donor screening, amnios were collected at Hospital Central Sur de Alta Especialidad (HCSAE), PEMEX and microbiological analysis was performed at Universidad Nacional Autónoma de México, FQUNAM, (Biology Dept. of the Chemistry Faculty, National Autonomous University of Mexico), before and after radiation sterilisation. Processing, packaging and sterilisation were performed at Instituto Nacional de Investigaciones Nucleares, ININ, (National Nuclear Research Institute). The patient, a ten-year-old boy with severe malnutrition, extensive loss of skin and pseudomonad infection in the whole body, was treated with gentle debridement in a Hubbard bath. Later amnion application was performed with sterilised amnios by using two different processes, in one of which the amnion was sterilised with paracetic acid, preserved in glycerol, kindly donated by the German Institute for Tissue and Cell Replacement and applied by Dr. Johannes C. Bruck, IAEA visiting expert, and the other amnion was processed at ININ: air dried and sterilised by gamma radiation at dose of 30 kGy. After spontaneous epithelisation was successfully promoted for seven days, the pain was alleviated and mobility was improved in a few hours and the patient's general condition was so improved that in a month he was discharged. Unfortunately, because this disease is revertive and has malignant degeneration, the prognosis is not good.

    The aim of this paper is to describe the early stages of Mexican nuclearization that took place in contact with radioisotopes. This history requires a multilayered narrative with an emphasis in North-South asymmetric relations, and in the value of education and training in the creation of international asymmetrical networks. Radioisotopes were involved in exchanges with the United States since the late 1940s, but also with Canada. We also describe the context of implementation of Eisenhower's Atoms for Peace initiative in Mexico that opened the door to training programs at both the Comisión Nacional de Energía Nuclear and the Universidad Nacional Autónoma de México. Radioisotopes became the best example of the peaceful applications of atomic energy, and as such they fitted the Mexican nuclearization process that was and still is defined by its commitment to pacifism. In 1955 Mexico became one of the 16 members of the atomic fallout network established by the United Nations. As part of this network, the first generation of Mexican (women) radio-chemists was trained. By the end of the 1960s, radioisotopes and biological markers were being produced in a research reactor, prepared and distributed by the CNEN within Mexico. We end up this paper with a brief reflection on North-South nuclear exchanges and the particularities of the Mexican case.

    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.

    Collections of mammals were made during more than three years of biological investigations in Chile sponsored by the Corporación Nacional Forestal under the aegis of the Peace Corps (Smithsonian Environmental Program). Genera and species hitherto unreported for that country were taken and many useful data concerning distributional patterns of other (mostly little-known) species were gathered. These collections have also proved valuable in better understanding Chilean mammals from a taxonomic point of view and contribute knowledge of the species' natural history. Specimens are to be deposited in the (United States) National Museum of Natural History (USNM) or are to be retained by the Corporación Nacional Forestal, Avda, Bulnes 285, Depto. 401, Santiago. Numbers provided below are field numbers. A final division of specimens between the two institutions has not yet been made. A number of specimens reported here were not taken by Peace Corps personnel but have been obtained by the National Museum of Natural History from other sources. Specimens in the Field Museum of Natural History (FMNH) were used in making comparisons. Some of Fulk's (GWF) specimens are at Texas Tech University. Other are at the Servicio Agricola y Ganadero in Santiago (as are specimens of some introduced species taken by Schamberger). Reise's (DF) are at the Universidad de Chile-Concepción and in his personal collection.

    The IBA conference has taken place in different countries from all over the world. It started in the United States in 1973, and since then has been held biennially without interruption, becoming the reference meeting on ion beam analysis and related methods and techniques. In its 17th edition, two Spanish laboratories, one from the Universidad de Sevilla and one from the Universidad Autónoma de Madrid had the honour and responsibility of organizing the conference. These two laboratories are, so far, the only ones in the country equipped with accelerators dedicated to ion beam analysis; the Centro Nacional de Aceleradores (CNA) in Seville and the Centro de Micro-Análisis de Materiales (CMAM) in Madrid. We took up this task enthusiastically, conscious that Spain has only very recently been equipped with IBA techniques and that this event would highlight to the scientific community of our country the importance and involvement of IBA techniques in new scientific and technological developments. The conference was held at the Melia Sevilla Hotel in Seville, Spain from 26 June-1 July 2005. This special issue of Nuclear Instruments and Methods in Physics Research B contains the published proceedings of the conference.

    MEGARA (Multi-Espectrógrafo en GTC de Alta Resolución para Astronomía) is the future intermediate-resolution optical Integral-Field Unit (IFU) and Multi-Object Spectrograph (MOS) of the 10.4m GTC telescope. The instrument can be used to observe either a contiguous (100% filling factor) field-of-view of 12.5×11.3 arcsec^{2} or 92 objects anywhere in a 3.5×3.5 arcmin^{2} field patrolled by robotic actuactors attached to optical-fiber minibundles, respectively in its IFU and MOS modes. The MEGARA Consortium is led by the Universidad Complutense de Madrid (UCM, Spain) and also includes the Instituto Nacional de Astrofísica, óptica y Electrónica (INAOE, Mexico), the Instituto de Astrofísica de Andalucía (IAA-CSIC, Spain) and the Universidad Politécnica de Madrid (UPM, Spain). The instrument passed its Critical Design Review (CDR) on late 2014 and is currently in construction phase with a planned date for the start of operations at GTC on early 2017. In this paper we summarize the main characteristics of the instrument and the status of the project.

    Bertha Lutz was one of the women of her generation who enjoyed indisputable political and scientific authority. She wrote much and even more was written about her, especially during her day. The newspaper chronicles by Lima Barreto, countless letters, scientific papers, and unpublished texts by Bertha herself that are surveyed in this article indicate how much her feminism--inseparable from other dimensions of her life--fostered her professional career. Her feminism earned her a carefully constructed renown and visibility that interlocked with her professional performance. Science lent her social prestige and guaranteed legitimacy for her causes. During a period when the scientific community itself was engaged in publicizing its own activities, Bertha's feminist prominence in the media helped her make a name in the sciences.

    Objetivos. Nos propusimos determinar el grado de preparación frente a los desastres naturales de los adultos mayores en los Estados Unidos y evaluar los factores que pueden afectar negativamente la salud y la seguridad durante este tipo de incidentes. Métodos. Obtuvimos una muestra de adultos de 50 años en adelante (n = 1 304) de la encuesta del 2010 del Estudio de la Salud y la Jubilación (HRS por su sigla en inglés). La encuesta recogió datos sobre las características demográficas generales, el estado de discapacidad o las limitaciones funcionales, y también sobre factores y comportamientos relacionados con la preparación frente a los desastres. Calculamos una puntuación global de preparación mediante indicadores individuales a fin de evaluar el grado de preparación general. Resultados. La media de la edad de los participantes (n = 1 304) fue de 70 años (desviación estándar [DE] = 9,3). Solo 34,3% informaron que habían participado en un programa formativo o que habían leído materiales sobre la preparación para los desastres. Casi 15% indicaron que usaban dispositivos médicos eléctricos que podían correr riesgo de no funcionar si se interrumpiera el suministro eléctrico. La puntuación de preparación indicó que la edad más avanzada, la discapacidad física y el menor nivel de escolaridad y de ingresos se asociaban independiente y significativamente a un grado de preparación general inferior. Conclusiones. A pesar de la mayor vulnerabilidad ante los desastres y del número cada vez mayor de adultos mayores en los Estados Unidos, muchos de los problemas sustanciales que encontramos son remediables y requieren atención en los sectores de la sociedad dedicados a la atención clínica, a la salud pública y al manejo de situaciones de emergencia.

    Up to now, the best treatment for patients with acute myelogenous leukemia (AML) is the induction of bone marrow hypoplasia by ablative combined chemotherapy; the prototype of these schedules is the so-called 7 + 3 (seven days of continuous infusion of cytarabine and three days of one-hour infusion of any anthracycline); these schedules require the support of both platelet transfusions and antibiotics. Other non-ablative schedules have also been tried in the treatment of such patients. Here we analyze the results of the treatment of 76 adult patients with AML; 43 were treated with the classical 7 + 3 schedule, whereas 33 were treated with a combination of chemotherapy used in non-ablative doses (TADOP: thioguanine, arabinosyl-citosine, doxorrubicin, vincristine and prednisone). The results were as follows, respectively, for 7 + 3 and TADOP: complete remission (CR) was achieved in 60 and 48% of patients (p NS); the number of cycles to achieve CR had a median of 1 and 5 months (p less than 0.001); the median duration of the CR was 21 and 10 months (p less than 0.05); fatal myelotoxicity was 30 and 42% (p NS), one-year disease free survival (DFS) was 45 and 46% (p NS) and three-year survival was 22% and 15% (p NS). Additionally, patients treated with 7 + 3 were divided into two groups according to the type of platelet transfusion support; those supported with apheresis equipment and those with centrifugation-derived platelets.(ABSTRACT TRUNCATED AT 250 WORDS)

    The purpose of this work was to study the volatile composition of vine leaves and vine leaf infusion prepared from vine leaves collected at 30 and 60 days after grape harvest of two Vitis vinifera L. species. Eighteen volatile compounds were identified by gas chromatography-mass spectrometry in vine leaves and in vine leaf infusions. It was observed that the volatile compounds present in vine leaves are dependent on the time of harvest, with benzaldehyde being the major volatile present in vine leaves collected at 30 days after harvesting. There are significant differences in the volatile composition of the leaves from the two grape cultivars, especially in the sample collected at 60 days after grape harvest. This is not reflected in the volatile composition of the vine leaf infusion made from this two cultivars, the more important being the harvesting date for the volatile profile of vine leaf infusion than the vine leaves grape cultivar.

    Neuroblastoma (NB) is the most frequent extracranial solid tumor in children according to the literature. In Mexico it is less frequent, fallen to 8th place. Our objective was to analyze our experience and compare it with the one reported in other countries. We included all patients admitted to our hospital during the previous five years and who had not received any treatment. Patients with stages I, II, and IV received cyclophosphamide and epirrubicin. Patients with stages were III and IV received the same chemotherapy alternating with cisplatinum., ifosfamide and etoposide during 12 months as well as massive doses of 131-MIBG and surgical ablation of the remaining tumor when possible. We included 30 patients, 25 with initial presentation in the abdomen. Five were in early stages and 20 (70%) were advanced with an overall survival of 100% and 27% at 5 years respectively. When analyzed by age, 40% were 12 months of age and 60% older, with survival of 100% and 27% in the same period, respectively. According to histology there was 91% survival for differentiated and 23% for undifferentiated tumors. The chemotherapeutic regimen reported is effective but not better than that reported by other authors, in which some benefits are seen with use of transplant and immunotherapy. The most important prognostic factors are still considered to be age, stage and histology.

    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.

    At low angles the scattering of X-rays in the diagnostic energy range (low-momentum transfer), it is probable that the scattering interaction will be coherent. This coherence gives rise to interference effects resulting in X-ray diffraction patterns that are characteristic of the scattering material. The usefulness of coherent scattering is not limited to crystallography. It can provide information about biological material as well. The interatomic and intermolecular co-operative effects which modify the free-atom coherent scattering process are well known for highly ordered structures such as crystalline materials but are important for amorphous solids and liquids where short-range ordering occurs. X-ray diffraction using synchrotron radiation has became a well established technique. This work introduces a non-destructive synchrotron radiation X-ray diffraction imaging technique. The feasibility of the X-ray diffraction computed microtomography using synchrotron radiation has been investigated. This research was carried out at the X-ray diffraction beam line of the National Synchrotron Light Laboratory supported by the National Council for Scientific and Technological Development (LNLS/CNPq) in Brazil. These experimental patterns were carried out with a 500 microm slit in front of the detector and an 11.101 keV beam (lambda = 1.117 A) monochromatic beam from the double crystal monochromator. The diffracted beam was detected by a fast scintillation detector (10(6) counts s(-1)) designed specifically to meet the needs of high quality X-ray diffraction and synchrotron radiation experiments. The data were recorded at rates of one second per degree of 2theta (angular steps equal to 0.05 +/- 0.01 degrees) and registered by a multichannel analyzer. These experimental data could be used to evaluate the scattering properties of different tissue-substitute (water, lucite, nylon, plastic and polystyrene) and bone-substitute (hydroxyapatite and aluminum) materials. The data are in good agreement with those obtained by other authors, indicating the feasibility of the imaging technique.

    During two full years--from October 1980 to September 1982--we captured sandflies in the National Park of Serra dos Orgãos, State of Rio de Janeiro, Brazil. The captures, with human bait, were carried out weekly, each with a duration of two hours, and at three different times (6 to 8 a.m., 5 to 7 a.m. and 7:30 to 9:30 p.m.). In every capture, we recorded the phase of the moon and, at each hour, the temperature, relative humidity, wind and rain. In 586 hours 4,834 sandflies of ten species were captured, all belonging to genus Lutzomyia França, 1924. L. ayrozai and L. hirsuta represented 92% of the total species captured. However, they were dominant at different times, the former being more frequent in the warm and wet months, and considerably declining in the cold and dry months, in which the latter gradually prevailed. L. fischeri and L. shannoni were shown to be the most resistant to unfavourable weather conditions. Whenever there was any rain or wind, they were, in general, the only species captured. With regard to lunar cycle, we observed that new moon was the most favourable phase for the capture of sandflies and full moon the one with the smallest yield, except for L. shannoni which occurred more frequently during this period.

    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.

    The collection of papers in this volume was presented during the X Mexican School on Gravitation and Mathematical Physics, which was held in Playa del Carmen, Quintana Roo, México, December 1-5, 2014. The Mexican School on Gravitation and Mathematical Physics is a series of conferences sponsored by the Mexican Physical Society that started in 1994 with the purposes of discussing and exchanging current ideas in gravitational physics. Each Mexican School has been devoted to a particular subject, and these have included supergravity, branes, black holes, the early Universe, observational cosmology, quantum gravity and numerical relativity. In this ocasion the theme of the school was Reaching a Century: Classical and Modified General Relativity's Attempts to explain the evolution of the Universe, which focused on the discussion of classical and modified aspects of general relativity. Following our previous Schools, world leaders in the field were invited to give courses and plenary lectures. More specialized talks were also presented in parallel sessions, and some of them have been included in these proceedings. The contributions in this volume have been reviewed and represent some of the courses, plenary talks and contributed talks presented during our X School. We are indebted to the contributors of these proceedings as well as to the rest of the participants in our Mexican School all for making of it a complete success. As for financial support we should mention the Mexican National Science and Technology Council (CONACyT), the Royal Society of London (UK), the Mexican Physical Society (SMF), as well as several Institutions including: Centro de Investigación y Estudios Avanzados (CINVESTAV), Universidad Autónoma Metropolitana Iztapalapa (UAM-I), Universidad de Guanajuato (UG), and Universidad Nacional Autónoma de México (UNAM).

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.

    The objective of this paper is to present our experience in the commissioning and quality assurance (QA) for intensity modulated radiotherapy (IMRT) using dynamic multileaf collimator (dMLC), sliding window technique. Using Varian equipment solution, the connectivity and operation between all IMRT chain components was checked. Then the following test were done: stability of leaf positioning and leaf speed, sensitivity to treatment interruptions (acceleration and deceleration), evaluation of standard field patterns, stability of dMLC output, segmental dose accuracy check, average leaf transmission, dosimetric leaf separation, effects of lateral disequilibrium between adjacent leaves in dose profiles and multiple carriage field verification. Standard patterns were generated for verification: uniform field, pyramid, hole, wedge, peaks and chair. Weekly QA Protocol include: sweeping gap output, Garden Fence Test (narrow bands, 2 mm wide, of exposure spaced at 2-cm intervals) and segmental dose accuracy check. Monthly QA include: sweeping gap output at multiple gantry and collimator angle, sweeping gap output off-axis, Picket Fence Test (eight consecutive movements of a 5-cm wide rectangular field spaced at 5-cm intervals), stability of leaf speed and leaf motor current test (PWM test). Patient QA procedure consists of an absolute dose measurement for all treatments fields in the treatment condition, analysis of actual leaf position versus planned leaf position (dynalog files) for each treatment field, film relative dose determination for each field, film relative dose determination for the plan (all treatment fields) in two axial planes and patient positioning verification with orthogonal films. The tests performed showed acceptable result. After more than one year of IMRT treatment the routine QA machine checks confirm the precision and stability of the IMRT system.

    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.

    Helicobacter pylori is associated with gastritis, peptic ulcer disease, and gastric cancer. Since gastric cancer is common in Peru, eradication of H. pylori may help to reduce the occurrence of gastric cancer. This study involved three randomized trials to determine the efficacy of four different triple-drug therapy regimens. The most successful regimen was furazolidone combined with bismuth subsalicylate and amoxicillin, which eradicated infection in 82% of patients. Patients successfully treated were followed every 2-3 months to determine the recurrence rate of H. pylori infection. Of 105 patients with H. pylori eradication documented by pathology and culture, 52% (55) returned for follow-up endoscopy, and in 73% (40) of these 55 the infection recurred during the 8-month follow-up period. Thirty-five patients from whom H. pylori was eradicated and who were tested for antibodies to H. pylori remained consistently seropositive. Rapid recurrence of H. pylori infection after successful eradication suggests that measures other than antimicrobial therapy are needed to fight H. pylori in developing countries.

    Patients undergoing hematopoietic cell transplantation (HCT) can have complications that require management in the intensive care unit (ICU). We conducted a retrospective study of patients undergoing HCT between 2007 and 2011 with admission to the ICU. We analyzed 97 patients, with an average age of 37 (range, 15 to 68). The main indications for HCT were hematologic malignancies (84%, n = 82). Ninety percent (n = 87) received myeloablative conditioning. Thirty-one percent were admitted (autologous transplant recipients 15%, allogeneic transplant recipients 34%, and umbilical cord blood [UCB] transplant recipients 48%) with an average length of stay of 19 days (range, 1 to 73 days). The average time between transplantation and transfer was 15 days. The main causes of admission were acute respiratory failure (63%) and septic shock (20%). ICU mortality was 20% for autologous transplantations and 64% for allogeneic transplantations (adult donor and UCB combined). On average, patients died 108 days after the transplantation (range, 4 to 320 days). One-year overall survival, comparing patients entering the ICU with those never admitted, was 16% versus 82% (P < .0001) for allogeneic transplantations (adult donor and UCB combined) and 80% versus 89% (P = not significant) for autologous transplantations. Acute graft-versus-host disease was significantly associated with death in ICU after UCB HCT. ICU support is satisfactory in about one half of patients admitted, characterized by a short and medium term prognosis not as unfavorable as has been previously reported.

    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.

    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.

The ore deposit is a lead-zinc, garnet-rich skarn developed at the contact between granite porphyry dikes (Eocene) and well-laminated limestones with interbedded chert (Albian-Cenomanian). A study of sulfur isotopes has been carried out in various sulfide minerals of the ores of Velardeña, in order to: (a) constrain the possible sources of sulfur and, therefore, better understand the sulfide mineralizing processes, and (b) to estimate the temperature of the ore-forming stage of the skarn. Sulfur isotope analyses were performed in 21 pure fractions of sulfide minerals of the ore mineralization (pyrite, chalcopyrite, sphalerite and galena). The mineral separation was performed using a series of sieves, and the purity of the samples was verified under a binocular microscope. Isotopic analyses were done on a Finnigan MAT Delta C flow elemental analyzer coupled to a TC-EA, according with the method of Giesemann et al. (1974). The δ34S values of the analyzed sulfides range mostly between -0.6 and +2.6 ‰ (relative to the CDT standard). These values are indicative of a magmatic source of sulfur. A single analysis falls

    sedimentation rates in different areas showing that in most of them sedimentation has increased significantly during the last century (by about one order of magnitude in most cases) and that such increase does not seem to be related to climate but rather to human activity. If a global geomorphic change is indeed taking place, an increase in the frequency/intensity of related hazards, such as landslides or floods, should be expected. Data are presented indicating that it could be so. If what the data presented suggest is confirmed by further and deeper analyses, existing hazard and risk assessments for those processes should be reconsidered, because they would likely represent underestimates.

    The Centro de Geociencias, at the Universidad Nacional Autonoma de Mexico, has published a series of booklets for children, entitled "Simple experiments to understand a complex Earth". It is part of the activities of the Mexican committee of the International Year of the Planet Earth. Each booklet contains experiments related with an Earth Sciences topic and includes the procedure to do one of the "Ten most beautiful experiments in physics" (Crease, P., Physics World May 2002 p17 and September 2002 pp19-20). In Mexico, as in other developing countries, there is very little information about Science in general and Earth Sciences in particular, in the basic education programs. Also, there is poor bibliography in Spanish about science experiments. For this reason, we try to fill the vacuum by distributing free the booklets in Science Museums and rural basic schools in paper, and by Internet in the Centro de Geociencias web site (http://www.geociencias.unam.mx/geociencias/difusion/indice.html). At present, we have been distributed 100,000 copies of 5 issues: 1."Atmospheric pressure and the falling bodies", it deals with the Galileo experiment of falling bodies, he proposed that all the bodies fall down at the same velocity. We discuss the properties of the atmosphere air (temperature, pressure and volume) and concluded that Galileo is right but when the bodies are very light. 2. "The light and the colors" is based in the Newton's decomposition of sunlight with a prism experiment. This booklet contains nine experiments to explain the colors that we find in Earth like the blue of the sky, the orange of the sunset, the rainbow and the mirage. 3. "¿Eureka! oceans and continents float". This booklet presents seven experiments related with density and buoyancy to explain the principles of the Plate tectonics theory. 4.

    Recent results in ionization collisions with positrons and protons showed that just above the two-body threshold, for electron velocities close to the final projectile's velocity, the electron-projectile continuum dipole is narrowly oriented along the direction of motion of its centre-of-mass, with the negative charge pointing towards the residual target. Although a forward-backward asymmetry in the vicinity of the two-body threshold has been studied many year ago in ion impact ionization collisions, that was by far a much milder effect that left no fingerprint on the cusp position. Our results show that the phenomena is present for ionization by impact of both protons and positrons. In this communication, through measurements on H+ + He and calculations we analyze in detail this effect that can be linked to a dynamical alignment of the two-body subsystem in the continuum.

    Several factors make observational astronomy difficult for astronomers; one of them is the atmosphere. The light that a star emits is refracted when it goes through the earth's atmosphere; the result of this is that the image of a punctual star is not what the physics would lead us to expect. At the Instituto de Astronomia of the Universidad Nacional Autonoma de México (IA-UNAM) an instrument has been developed called "Berkut", which uses a high resolution technique to improve these effects and obtain interesting and valuable scientific studies. In this paper we present the mechanical reengineering and acceptance test of Berkut. This instrument was design for taking images of high resolution. Essentially, it is composed by a set basic optics which is aligned and in focus with a 1- meter class telescope. It has its own electronic components for controlling remotely a filter wheel; that allows the exchange of the filters according to the requirements of the observer, a couple of objectives mounted in a translation stage, and a CCD camera for acquiring several images per second that are used in the speckle interferometry technique. A project like Berkut needs to be multidisciplinary; astronomy, engineering, optics, mechanics, electronics, and image processing are some of the areas of knowledge used. Berkut will be used in the telescope of the Observatorio Astronomico Nacional in Tonantzintla, located in the state of Puebla, Mexico, but it can be used in any telescope 1 meter class. It is pretended to build another Berkuts for being used simultaneously in different telescopes, so it is important to keep the costs as low as possible. With this instrument we pretend to confirm the Hipparcos catalogue of binary stars besides finding exoplanets.

    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

    We use acceleration data from the Observatorio Vulcanologico y Sismologico, Universidad Nacional de Costa Rica (OVSICORI-UNA) and Laboratorio de Ingenieria Sismica, Universidad de Costa Rica (LIS-UCR) seismic network for the relocation and moment-tensor solution of the September 5, 2012, 14:42:03.35 UTC, Nicoya, Costa Rica earthquake (Mw 7.6 GCMT). Using different relocation methods we found a stable earthquake hypocenter, near the original OVSICORI-UNA location in the Nicoya Peninsula, NW Costa Rica at Lat 9.6943°N, Lon 85.5689°W, depth 15.3 km, associated with the subduction of the Cocos plate under Caribbean plate. Acceleration records at OVSICORI-UNA and LIS-UCR stations (94-171 km), at 0.03 < f < 0.06 Hz were used in the waveform inversion for a single-point centroid moment tensor (CMT). Using spatial grid search the centroid position was found at the depth of 30 km, situated at Lat 10.0559°N, Lon 85.4778°W, i.e. of about 41 km NNE from the epicenter. The centroid time is 14:42:18.89 UTC, i.e. 15.54 s later relative to the location-based origin time. The nodal plane (strike 318°, dip 27° and rake 115°) is the fault plane that agrees with the geometry of the subducted slab at Nicoya, NNW Costa Rica. Increasing the maximum studied frequency from 0.06 to 0.15 Hz, the multiple point source inversion model leads to two subevents. The first one was located near the centroid and the second subevent was situated 20 km along strike and 10 km down dip from the first subevent and 6 s later. The uncertainty of the source model was carefully examined using complementary inversion methods, viz the iterative deconvolution and non-negative least squares.

    The use of bortezomib as a treatment modality of AHR improved and stabilized graft function (clinical response) in the majority of patients. Its use in single dose, even combined with rituximab, does not seem to be useful to obtain a sustained clinical response, or to reduce HLAabs level. The use of 4 doses of bortezomib in days 1, 4, 7, and 10 (1.3 mg/m2 BSA each) plus plasmapheresis produced both a good clinical response and a reduction in DSA. Moving forward, it will be necessary to define the long-term effectiveness of bortezomib and whether rituximab administration is indispensable to achieve this goal. Until now, it is evident that many patients needed retreatment and they were well tolerated.

    The goal of this presentation is the description of the epidemiologic evolution and changes in natural history of the human immunodeficiency virus infection (HIV) epidemic itself and its relation with the acquired immunodeficiency syndrome-related lymphoma (ARL). We have started with the description of the world's state of the HIV epidemic, its features since the first case report in the United States of America in 1981, through the peak of new diagnoses in 1993 until the event that changed the natural history of the disease: the era of the widespread use of the highly active antiretroviral therapy (HAART), introduced in 1995 in the world and in 1997 in our country. The widespread introduction of HAART led to dramatic reductions in AIDS related mortality and morbidity throughout the developed world with a marked fall in the incidence of the major opportunistic infections in AIDS. We describe the main risk factors for the development of ARL, and the prognostic factors for survival and response to treatment. There is no clear definition in the literature of the roll that has played the use of HAART in relation to survival and response to treatment in ARL, but there is evidence that the basal count of CD4 cells has increased with HAART, leading to a better survival and response in ARL. The debate regarding this issue is surely affected by factors such as degree of antiretroviral treatment compliance, antiretroviral therapy resistance and chemotherapy heterogeneity. Finally we present the preliminary results of the analysis of our experience in ARL from 1986 to 2003.

    This is a retrospective study that includes four decades of kidney transplant program at our Institute, with a total of 923 kidney transplants in 872 recipients. In this report, the effect of variables in recipient, donor, and transplant on long-term graft survival was analyzed using the Kaplan Meier method with log-rank test for survival comparisons. Global graft survival at our center-analyzed by censoring for death-with-functioning-graft-for 1, 5 and 10 years was 93%, 83% and 74%, respectively, with median survival of 24.5 years. When analyzed for all-cause graft loss, 1, 5 and 10 year survival was 90%, 76% and 61%, with 12.8-year median survival. Variables associated with lower graft survival censored for death-with-functioning-graft were transplantation in an earlier decade, less histocompatibility, younger kidney transplant recipients, no induction therapy, and double drug initial immunosuppression. After Cox's regression multivariate analysis, the risk factors that remained associated with worse survival were younger recipient, earlier transplant decade, and deceased donor.

    The introduction of exotic species is considered as one of the major causes of biodiversity loss. The National Forest of Carajás is one of the largest mineral provinces in the world. Mining activities caused changes of the natural habitats, leaving degraded areas after the mineral exploitation. One of the mining areas within FLONA Carajás was used for the extraction of gold. In the process of exploitation, a huge depression was formed by the removal of soil which was mounded up nearby. To prevent soil erosion of these mounds, an exotic grass, Urochloa decumbens (Stapf) R.D.Webster (Poaceae) was planted. The objective of this study was to compare the impact of this non-native grass on species richness and species composition of the natural regeneration in the degraded areas. Four areas were compared, two with and two without presence of U. decumbens. In each area, twenty four 1m²/plots were established. Species richness of the regeneration areas and population sizes were significantly lower in the plots where the exotic grass was present. Our study shows that U. decumbens had a negative effect on species richness and population density, and its presence changed the species composition and distribution of life forms of the natural regeneration.

    Chaitén volcano in southern Andes started a plinian to subplinian rhyolitic eruption on May 2008 following a long period of quiescence. A new dome complex grew up at high rates during 2008-2009 inside a 2 kilometers caldera like structure. Pyroclastic, laharic, block and ash flows and ash falls deposits have been affecting the surrounding populations, ground, vegetation, ocean and rivers, such as the laharic flows burying the currently evacuated Chaitén city. The geological, volcanologic and seismic knowledge produced during the eruption and the determination of evolutionary sceneries were properly transferred and consequently taken in account during complex decisions of authorities in charge of the emergency. As a result, no fatalities or major people injuries were produced during this rhyolitic eruption. Mainly as the consequence of the eruption of the Chaitén volcano but also due to the valuable technical advice during the crisis management, evacuation, hazards evolution, volcanic alerts and selection of sites for relocation of the Chaitén city provided by geologist and volcanologist from SERNAGEOMIN, the funding for the National Volcano Monitoring Network (RNVV) was approved during 2008 and it was integrated as a Bicentenary initiative. During the lapse of 5 year, RNVV need to create professional capacity and working teams, improve the current volcano observatory at Temuco and conform three new observatories at Coihaique, Talca and Antofagasta cities to implement volcano monitoring networks at the 43 hazardous volcanoes along the Chilean Andes. Monitoring net is currently conformed by seismic stations in 10 volcanoes or volcanic groups (San Pedro-San Pablo in Central Volcanic Andes and Llaima, Villlarrica, Mocho-Choshuenco, Carrán-Los Venados, Cordón Caulle, Osorno, Calbuco, Chaitén and Melimoyu in the southern volcanic Andes), in addition to gas measure and video camera stations in Llaima, Villarrica and Chaitén volcanoes. In addition, the geologic and volcanologic knowledge is currently transferred to authorities and expose communities in order to improve their preparation and capacity to mitigate effects of volcanic eruptions on people, economy and country structure.

    Institutions involved in training health professionals are permanently concerned with improving the quality of their graduates and their skills for meeting healthcare demands. Research has been conducted in the field of health education and related areas with the purpose of identifying the incidence of high-school GPAs, learning styles and demographic factors on pre-university performance of students. It has been widely assumed that performance at this stage is one of the best predictors of subsequent academic performance. In the year 2000 the School of Medicine of the Universidad Nacional de Córdoba introduced an Entrance Examination as part of a comprehensive curricular reform. Therefore, the study of the predictors of performance in the entrance examination can be a valuable contribution to pedagogical decision making. Our aim is to assess the predictive capacity of a series of indicators associated to the population of candidates attempting entrance to medical studies. The survey comprises the period 2006-2008. The variables under study are: sociodemographic characteristics, high-school specialization, and high-school grade point average (GPA). ANOVA was applied to measurable variables, whereas attribute variables were submitted to categorical data and multiple correspondence analyses. We conclude that predictors are associated to sociocultural factors related to family environment, mainly educational level of the mother, and to a high-school GPA value between 8 and 9 points.

    Paraguay has eight public universities and 45 private universities. The National University of Caaguazú (Universidad Nacional de Caaguazú or UNCA), with its main campus located in Coronel Oviedo, is one of the most recently founded public universities, being established in 2007. The UNCA has launched a project aiming at exploring the potentiality of its educational system, as well as its gaps. In particular, the UNCA wants to assess the effectiveness of preparatory courses for preparing students for admission to the degree course in medicine (Cursos Probatorios de Ingreso or CPI), in order to identify the main strong and weak points of the system, the popularity and usefulness of CPI as perceived by the students, the students’ and teachers’ opinions regarding the limits of school, and their suggestions. This paper is based on a field survey and highlights the care that must be taken in order to develop conditions respectful of the wellbeing of those participating in the educational context.

    Recent Hubble Space Telescope images have allowed the determination with unprecedented accuracy of motions and changes of shocks within the inner Orion Nebula. These originate from collimated outflows from very young stars, some within the ionized portion of the nebula and others within the host molecular cloud. We have doubled the number of Herbig-Haro objects known within the inner Orion Nebula. We find that the best-known Herbig-Haro shocks originate from relatively few stars, with the optically visible X-ray source COUP 666 driving many of them. While some isolated shocks are driven by single collimated outflows, many groups of shocks are the result of a single stellar source having jets oriented in multiple directions at similar times. This explains the feature that shocks aligned in opposite directions in the plane of the sky are usually blueshifted because the redshifted outflows pass into the optically thick photon-dominated region behind the nebula. There are two regions from which optical outflows originate for which there are no candidate sources in the SIMBAD database.

  4. Surface-deposition and distribution of the radon-decay products indoors.

    The exposure to radon-decay products is of great concern both in dwellings and workplaces. The model to estimate the lung dose refers to the deposition mechanisms and particle sizes. Unfortunately, most of the dose data available are based on the measurement of radon concentration and the concentration of radon decay products. These combined measurements are widely used in spite of the fact that accurate dose assessments require information on the particle deposition mechanisms and the spatial distribution of radon decay products indoors. Most of the airborne particles and/or radon decay products are deposited onto indoor surfaces, which deposition makes the radon decay products unavailable for inhalation. These deposition processes, if properly known, could be successfully exploited to reduce the exposure to radon decay products. In spite of the importance of the surface deposition of the radon decay products, both for the correct evaluation of the dose and for reducing the exposure; little or no efforts have been made to investigate these deposition processes. Recently, two parallel investigations have been carried out in Rome and at Universidad Nacional Autónoma de México (UNAM) in Mexico City respectively, which address the issue of the surface-deposited radon decay products. Even though these investigations have been carried independently, they complement one another. It is with these considerations in mind that it was decided to report both investigations in the same paper.

    In this paper we present the results of an analysis on a large part of the existing Image data from the OSIRIS camera system onboard the Rosetta Spacecraft, in which stars of sufficient brightness (down to a limiting magnitude of 6) have been observed through the coma of Comet 67/P Churyumov-Gerasimenko ("C-G"). Over the course of the Rosetta main mission the Coma of the comet underwent large changes in density and structure, owed to the changing insolation along the orbit of C-G. We report on the changes of the stellar signals in the wavelength ranges, covered by the filters of the OSIRIS Narrow-Angle (NAC) and Wide-Angle (WAC) cameras.Acknowledgements: OSIRIS was built by a consortium led by the Max-Planck-Institut für Sonnensystemforschung, Göttingen, Germany, in collaboration with CISAS, University of Padova, Italy, the Laboratoire d'Astrophysique de Marseille, France, the Instituto de Astrofísica de Andalucia, CSIC, Granada, Spain, the Scientific Support Office of the European Space Agency, Noordwijk, The Netherlands, the Instituto Nacional de Técnica Aeroespacial, Madrid, Spain, the Universidad Politéchnica de Madrid, Spain, the Department of Physics and Astronomy of Uppsala University, Sweden, and the Institut für Datentechnik und Kommunikationsnetze der Technischen Universität Braunschweig, Germany.

    In the year 2003, in the Faculty of Medicine of the Universidad Nacional Mayor de San Marcos, the Permanent Program of Training for the Integral Attention of the Victims of Violence was created, has been training human resources for the comprehensive health care to victims of violence. In this sense, we was considered necessary to develop a methodology for health professionals, identifying their training needs and the conditions under how they work. It is in this context, that the year 2004, a base line study was delineated in the Microrred de Salud Huaycán, in the east of Lima city; that included diverse stages with a multisectorial approach with the aim to identify the training needs of the health professionals, as well as the evaluation of the logistic and administrative support for the development of training activities to diverse levels. In this paper, the procedures and principal results are exposed, in a succinct way. There was demonstrated that the population of Huaycán were affected by the sequels of the political violence; nevertheless, the health services have severe limited resources to give appropriate health care to victims of violence. The health professionals require an intensive training on this issue. An adequate logistic and administrative conditions allowed to carry out an appropriate training program. We suggest that this methodology will facilitate to construct products and instruments for a suitable and specific training for the integral health care to the victims of the violence.

    Ongoing work in the field of Musical Acoustics (among other areas of interest) has been carried out at the Acoustics Laboratory at the Centro de Investigaciones Aplicadas y Desarrollo Tecnologico in the Universidad Nacional Autonoma de Mexico (UNAM). This research began almost 15 years ago and although there have been times when no work was made, due to the effort involved in the characterization of the chambers at this laboratory and the development of other areas, some results are worth mentioning. In this paper the main work done in the laboratory in the field of musical acoustics, in particular, that related to the guitar is summarized. The topics studied so far deal with the objective and subjective evaluation of the sound of the guitar, the role of high frequency radiation, the string-body interaction and tuning problems, and the fretboard's influence on the sound radiation, among other things. Most of this work has been published elsewhere, but the aim in this presentation is to give a general view of the work done by the Acoustics Laboratory, to the author's acknowledge, the only group in Mexico working in this area.

    Curzio, O. A.; Croci, C. A.

    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.

    OSIRIS (Optical System for Imaging and low Resolution Integrated Spectroscopy) was the optical Day One instrument for the 10.4m Spanish telescope GTC. It is installed at the Observatorio del Roque de Los Muchachos (La Palma, Spain). This instrument has been operational since March-2009 and covers from 360 to 1000 nm. OSIRIS observing modes include direct imaging with tunable and conventional filters, long slit and low resolution spectroscopy. OSIRIS wide field of view and high efficiency provide a powerful tool for the scientific exploitation of GTC. OSIRIS was developed by a Consortium formed by the Instituto de Astrofísica de Canarias (IAC) and the Instituto de Astronomía de la Universidad Nacional Autónoma de México (IA-UNAM). The latter was in charge of the optical design, the manufacture of the camera and collaboration in the assembly, integration and verification process. The IAC was responsible for the remaining design of the instrument and it was the project leader. The present paper considers the development of the instrument from its design to its present situation in which is in used by the scientific community.

    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.

    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).

    The Astronomical Resource Cross-matching for High Energy Studies (ARCHES) project is a FP7-Space funded programme started in 2013 and involving the Observatoire Astronomique de Strasbourg including the CDS (France), the Leibniz- Institut für Astrophysik Potsdam (Germany), the University of Leicester (UK), the Universidad de Cantabria (IFCA, Spain) and the Instituto Nacional de Tecnica Aeroespacial (Spain). ARCHES will provide the international astronomical community with well-characterised multi-wavelength data in the form of spectral energy distributions (SEDs) for large samples of objects extracted from the 3XMM X-ray catalogue of serendipitous sources. The project develops new tools implementing fully probabilistic simultaneous cross-correlation of several catalogues and a multi-wavelength finder for clusters of galaxies. SEDs are based on an enhanced version of the 3XMM catalogue and on a careful selection of the most relevant multi-wavelength archival catalogues. In order to ensure the largest audience, SEDs will be distributed to the international community through CDS services and through the Virtual Observatory. These enhanced resources are tested in the framework of several science cases. More information may be found at http://www.arches-fp7.eu/

    EMIR is a near-IR, multi-slit camera-spectrograph under development for the 10m GTC on La Palma. It will deliver up to 45 independent R equals 3500-4000 spectra of sources over a field of view of 6 feet by 3 feet, and allow NIR imaging over a 6 foot by 6 foot FOV, with spatial sampling of 0.175 inch/pixel. The prime science goal of the instrument is to open K-band, wide field multi-object spectroscopy on 10m class telescopes. Science applications range from the study of star-forming galaxies beyond z equals 2, to observations of substellar objects and dust-enshrouded star formation regions. Main technological challenges include the large optics, the mechanical and thermal stability and the need to implement a mask exchange mechanism that does not require warming up the spectrograph. EMIR is begin developed by the Instituto de Astrofisica de Canarias, the Instituto Nacional de Tecnica Aeroespacial, the Universidad Complutense de Madrid, the Observatoire Midi-Pyrennees, and the University of Durham. Currently in its Preliminary Design phase, EMIR is expected to start science operation in 2004.

    Over the last years, scientific interest for designing and making low dimensional electronic devices with traditional or novel materials has been increased. These experimental and theoretical researches in electronic properties at molecular scale are looking for developing efficient devices able to carry out tasks which are currently done by silicon transistors and devices. Among the new materials DNA strands are highlighted, but the experimental results have been contradictories pointing to behaviors as conductor, semiconductor or insulator. To contribute to the understanding of the origin of the disparity of the measurements, we perform a numerical calculation of the electrical conductance of DNA segments, modeled as 1D disordered finite chains. The system is described into a Tight binding model with nearest neighbor interactions and a s orbital per site. Hydration effects are included as random variations of self-energies. The electronic current as a function of applied bias is calculated using Launder formalism, where the transmission probability is determined into the transfer matrix formalism. We find a conductor-to-semiconductor-to-insulator transition as a function of the three effects taken into account: chain size, intrinsic disorder, and hydration We thank Fundación para la Promoción de la Investigación y la Tecnología, Colombia, and Dirección de Investigación de Bogotá, Universidad Nacional de Colombia, for partial financial support.

    Coccidioidin, an extract from the saprophytic mycelial form of Coccidioides spp., has been a very useful antigen preparation both for skin and serological tests for coccidioidomycosis. Unfortunately, coccidioidin is not currently available for skin testing in the United States. Coccidioidin has been produced commercially in Mexico by a vaccine and reagents laboratory of the Mexican Federal Government. It also has been produced at the Microbiology Laboratory of the Faculty of Medicine, Universidad Nacional Autónoma de México exclusively as an antigen for research projects. The objective of the study was to compare both coccidioidins in their reactivity and safety when applied in humans. One hundred and eighty-four volunteers were tested; median age was 33 (range 14-82). When the cutoff point is set in 5 mm, 88 subjects (47.8%) had a positive test for the commercial coccidioidin and 76 (41.3%; CI(95%) 0.50, 1.15; P = 0.20) were positive with the research antigen. Seventy-five subjects were positive for both antigens and 96 were negative for both. Fifty-nine subjects (31.3%) reported an adverse reaction after the application of the antigen; they were mostly very mild local reactions. Mexican research coccidioidin is a safe and reliable antigen that can be used for the detection of coccidioidomycosis infection in mammals.

    The acquisition of the two research vessels (R/V EL PUMA AND R/V JUSTO SIERRA) of the Universidad Nacional Autónoma de México represented a milestone for the development of oceanography and capacity building in Mexico. These boats were designed to conduct multi and interdisciplinary research in the Economic Exclusive Zone of Mexico in the main areas of oceanography (Physics, Geology, Chemistry and Biology). Its use, by different institutions, resulted in a substantial advancement of the knowledge of Marine ecosystems of Mexico. About 460 oceanographic campaigns, with more than 8700 participants, have been conducted since the boats arrived. These covered a wide array of topics of the marine ecosystem from the inner shelf to deep sea. Extensive research was done on current patterns, primary productivity and pollution monitoring of the Mexican Pacific, Sea of Cortez, Gulf of Mexico and Caribbean sea. Marine biodiversity studies were also carried which discovered more than 180 new species in Mexican seas. Ecological characterization and paleo-oceanographic research from continental shelf to deep sea also registered a substantial advance. The vessels are now renewed with hi-tech equipment for sea bottom, water column and navigation that increased their research capacity, representing again a new milestone in the history of oceanography in Mexico. This improved capacity is very promising and opens new and sound opportunities for carrying modern oceanographic in order to improve knowledge of the Mexican Economic Exclusive Zone.

    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.

    The combination of satellite data and ground based measurements can provide valuable information about atmospheric chemistry and air quality. In this work we present a comparison between measured ground based NO2 differential columns at the Universidad Nacional Autónoma de México (UNAM) in Mexico City, using the Differential Optical Absorption Spectroscopy (DOAS) technique and NO2 total columns measured by the Ozone Monitoring Instrument (OMI) onboard the Aura satellite using the same measurement technique. From these data, distribution maps of average NO2 above the Mexico basin were constructed and hot spots inside the city could be identified. In addition, a clear footprint was detected from the Tula industrial area, ~50 km northwest of Mexico City, where a refinery, a power plant and other industries are located. A less defined footprint was identified in the Cuernavaca basin, South of Mexico City, and the nearby cities of Toluca and Puebla do not present strong enhancements in the NO2 total columns. With this study we expect to cross-validate space and ground measurements and provide useful information for future studies.

    The phase diagram of chiral liquid crystals confined in ellipsoids is obtained, by following a theoretically informed Monte Carlo relaxation of the tensor alignment field Q. The free energy of the system is described by a functional in the framework of the Landau-de Gennes formalism. This study also includes the effect of anchoring strength, curvature, and chirality of the system. In the low chirality region of the phase diagram we found the twist bipolar (BS) phase and some cholesteric phases such as the radial spherical structure (RSS), twist cylinder (TC) and double twist cylinder (DTC) whose axis of rotation is not necessarily aligned with the major axis of the geometry. For high chirality scenarios, the disclination lines are twisted or bent near the surface preventing the formation of symmetric networks of defects, although an hexagonal pattern is formed on the surface which might serve as open sites for collocation of colloids. By analyzing the free energies of isochoric systems, prolate geometries tend to be more favorable for high chirality and low anchoring conditions.

    2008-12-01

    Anomalous behavior in commercial and pet birds in Mexico City was reported during 2002 by veterinarians at the Universidad Nacional Autonoma de Mexico. This was attributed to variations in the surrounding luminosity. The solar components, direct, diffuse, global, ultraviolet band A and B, as well as some meteorological parameters, temperature, relative humidity, and precipitation, were then analyzed at the Solar Radiation Laboratory. Although the total annual radiance of the previously mentioned radiation components did not show important changes, ultraviolet Band-B solar radiation did vary significantly. During 2001 the total annual irradiance , 61.05 Hjcm² to 58.32 Hjcm², was 1.6 standard deviations lower than one year later, in 2002 and increased above the mean total annual irradiance, to 65.75 Hjcm², 2.04 standard deviations, giving a total of 3.73 standard deviations for 2001-2002. Since these differences did not show up clearly in the other solar radiation components, daily extra-atmosphere irradiance was analyzed and used to calculate the total annual extra-atmosphere irradiance, which showed a descent for 2001. Our conclusions imply that Ultraviolet Band-B solar radiation is representative of solar activity and has an important impact on commercial activity related with birds.

    CUBES is a high-efficiency, medium-resolution (R ≃ 20, 000) spectrograph dedicated to the "ground based UV" (approximately the wavelength range from 300 to 400nm) destined for the Cassegrain focus of one of ESO's VLT unit telescopes in 2018/19. The CUBES project is a joint venture between ESO and Instituto de Astronomia, Geofísica e Ciências Atmosféricas (IAG) at the Universidade de São Paulo and the Brazilian Laboratório Nacional de Astrofísica (LNA). CUBES will provide access to a wealth of new and relevant information for stellar as well as extra-galactic sources. Principle science cases include the study of heavy elements in metal-poor stars, the direct determination of carbon, nitrogen and oxygen abundances by study of molecular bands in the UV range and the determination of the Beryllium abundance as well as the study of active galactic nuclei and the inter-galactic medium. With a streamlined modern instrument design, high efficiency dispersing elements and UV-sensitive detectors, it will enable a significant gain in sensitivity over existing ground based medium-high resolution spectrographs enabling vastly increased sample sizes accessible to the astronomical community. We present here a brief overview of the project, introducing the science cases that drive the design and discussing the design options and technological challenges.

    This paper is framed within the area of medical image processing and aims to present the process of installation, configuration and implementation of a processing server of medical images (MIPS) in the Fundación Escuela de Medicina Nuclear located in Mendoza, Argentina (FUESMEN). It has been developed in the Gabinete de Tecnologia Médica (GA.TE.ME), Facultad de Ingeniería-Universidad Nacional de San Juan. MIPS is a software that using the DICOM standard, can receive medical imaging studies of different modalities or viewing stations, then it executes algorithms and finally returns the results to other devices. To achieve the objectives previously mentioned, preliminary tests were conducted in the laboratory. More over, tools were remotely installed in clinical enviroment. The appropiate protocols for setting up and using them in different services were established once defined those suitable algorithms. Finally, it’s important to focus on the implementation and training that is provided in FUESMEN, using nuclear medicine quality control processes. Results on implementation are exposed in this work.

    Unidad de Educacion Continua y a Distancia, Universidad Nacional Autonoma de Mexico, Coyoaca 04510 Mexico, MEXICO As stated in the special session description, 21st century undergraduate education has access to resources/experiences that go beyond university classrooms. However in some cases, resources may go largely unused and a number of factors may be cited such as logistic problems, restricted internet and telecommunication service access, miss-information, etc. We present and comment on our efforts and experiences at the National University of Mexico in a new unit dedicated to teleconferences and audio-visual materials. The unit forms part of the geosciences institutes, located in the central UNAM campus and campuses in other States. The use of teleconference in formal graduate and undergraduate education allows teachers and lecturers to distribute course material as in classrooms. Course by teleconference requires learning and student and teacher effort without physical contact, but they have access to multimedia available to support their exhibition. Well selected multimedia material allows the students to identify and recognize digital information to aid understanding natural phenomena integral to Earth Sciences. Cooperation with international partnerships providing access to new materials and experiences and to field practices will greatly add to our efforts. We will present specific examples of the experiences that we have at the Earth Sciences Postgraduate Program of UNAM with the use of technology in the education in geosciences.

    The 2010 undergraduate medical degree curriculum at the faculty of medicine of the Universidad Nacional Autonoma de Mexico (UNAM) constitutes an important curricular reform of medical education in our country. It is the result of an institutional reflective process and academic dialog, which culminated in its approval by UNAM’s Academic Council for the Biology, Chemistry, and Health Sciences areas on February 2nd, 2010. Some distinguishing characteristics of the new academic curriculum are: organization by courses with a focus on outcome competencies; three curricular axes that link three knowledge areas; four educational phases with achievement profiles; new courses (biomedical informatics, basic-clinical and clinical-basic integration, among others); and core curriculum. The aforementioned curriculum was decided within a framework of effective teaching strategies, competency oriented learning assessment methods, restructuring of the training of teaching staff, and establishment of a curriculum committee follow-up and evaluation of the program. Curricular change in medical education is a complex process through which the institution can achieve its mission and vision. This change process faces challenges and opportunities, and requires strategic planning with long-term foresight to guarantee a successful dynamic transition for students, teachers, and for the institution itself.

    pepe@geo.igp.gob.pe Beginning in 1937, the Carnegie Institution of Washington made active regional observations with a spectro-helioscope at the Huancayo Observatory. In 1957, during the celebration of the International Geophysical Year Mutsumi Ishitsuka arrived at the Geophysical Institute of Peru and restarted solar observations from the Huancayo Observatory. Almost 69 years have passed and many contributions for the geophysical and solar sciences have been made. Now the Instituto Geofisico del Peru (IGP), in cooperation with the Faculty of Sciences of the Universidad Nacional San Luis Gonzaga de Ica (UNICA), and with the support of the National Astronomical Observatory of Japan, are planning to construct a solar station refurbishing a coelostat that worked for many years at the Huancayo Observatory. A 15 cm refractor telescope is already installed at the university, for the observation of sunspots. A solar Flare Monitor Telescope (FMT) from Hida Observatory of Kyoto University could be sent to Peru and installed at the solar station at UNICA. As the refurbished coelostat, FMT will become a good tool to improve education and research in sciences.

    Since 2006 projects have been carried out in the Universidad Nacional de Tucuman to introduce Telemedicine in the Provincial System of Health (SIPROSA) in Tucuman, Argentina. These projects aim at improving accessibility to remote populations, providing equity and avoiding costly and unnecessary transfers as well as helping early diagnosis and treatments, timely and appropriate referrals. On the other hand, this consultation has already been set up within the SIPROSA with the application of the system of reference and counter-reference for several years. By applying Telemedicine it is possible to accelerate the times and make this more efficient. This paper presents a prototype Web application for performing consultation in dermatology. These were conducted by professionals in Ranchillos, a small town within the Province, together with specialists from the capital city. After the experience, it can be said that the teledermatological application of the platform has been well received by physicians and dermatologists of rural areas, especially because the interfaces could be adjusted to their requirements. The physicians consider it a useful tool to complete the process of referral and counter-referral.

  10. Calculation of the superconducting transition temperature of a graphene layer doped with titanium and palladium

    Vazquez, Gerardo; Magana, Fernando; Salas-Torres, Osiris

    We explore the structural interactions between graphene and transition metals such as palladium (Pd) and titanium (Ti) and the possibility of inducing superconductivity in a graphene sheet in two cases, one by doping its surface with palladium atoms sit on the center of the hexagons of the graphene layer and other by covering the graphene layer with two layers of titanium metal atoms. The results here were obtained from first-principles density functional theory in the local density approximation. The Quantum-Espresso package was used with norm conserving pseudopotentials. All of the structures considered were relaxed to their minimum energy configuration. Phonon frequencies were calculated using the linear-response technique on several phonon wave-vector mesh. The electron-phonon coupling parameter was calculated with several electron momentum k-mesh. The superconducting critical temperature was estimated using the Allen-Dynes formula with μ* = 0.1 - 0.15. We note that palladium and titanium are good candidate materials to show a metal-to-superconductor transition.

    The first vineyard or surround concert hall designed and built in the Western Hemisphere is the Sala Nezahualcoyotl in Mexico City. The Hall was completed in 1976 and is part of the Cultural Center at the Universidad Nacional Autonoma de Mexico. The hall was named after a Toltec poet, architect, and musician who lived in the 15th century and was the Renaissance man of his day. In order to provide the familiar traditional sound of the rectangular (shoebox) European Hall, the acoustic designers set the criteria for reverberation times through the frequency spectrum and the Initial Time Delay Gap at every seat in the house to match the measurements taken at the Grosser Musik vereinssaal in Vienna and Boston Symphony Hall. In this paper we discuss the techniques used to create the traditional sound in a vineyard hall and the reaction of musicians and audiences to the completed facility. The Sala was the model for Suntory Hall in Japan which in turn spawned a number of vineyard halls in Japan. Most recently, the vineyard style seems to be appealing to more and more symphonic organizations in Europe and North America.

    Hace 80 años, la Escuela de Medicina de la Universidad Nacional, en voz de su director, Gustavo Baz Prada, hizo una propuesta que pronto se convirtió en realidad y finalmente en norma, la que desde entonces se conoce como SS. Esta iniciativa se vio como una manera para que los estudiantes de medicina del último año retribuyeran a la sociedad una parte de lo que esta invirtió en su educación, consolidaran su formación mediante la exposición a las realidades de todos los días en los medios más necesitados, se pusieran a prueba sobre sus verdaderas capacidades para atender pacientes y participaran en la solución de un problema de atención sanitaria que en ese entonces era mucho más apremiante que ahora. Unos años después, los recién egresados de otras licenciaturas (pasantes) también fueron incorporados a esta estrategia y, al fin, se reconoció formalmente como una responsabilidad de las instituciones educativas. Las aportaciones del SS a la salud de las personas y a la formación de los médicos han sido incuestionables, y la experiencia humana que ha representado para quienes lo han vivido ha dejado marcas indelebles.

    Chlamydia trachomatis genital infection is nowadays considered one of the most frequent causes of sexually transmitted infections (STI) in the world, mainly affecting the group of young people under 25 years old. The aim of this study was to determine the prevalence of C. trachomatis infection in newly admitted students to Universidad Nacional del Sur, Bahía Blanca, Argentina, and to evaluate the risk factors to acquire STI. For that purpose, 204 young college students with a mean age of 19 were involved in this study. Each participant delivered a sample of first-void urine and completed a questionnaire which was then submitted anonymously. The research for C. trachomatis was done on 114 valid samples through a technique of DNA amplification, whose molecular target was the gene ompA. Four cases of infection by C. trachomatis were detected with a prevalence of 3.5%. The risks factors associated to the infection were a history of 7 or more partners since the start of sexual activity and contact with a new sexual partner in the last 4 months. The prevalence of such infection reflects a moderate circulation of this microorganism in the studied population. This fact, along with some aspects shown by the questionnaire results, would characterize a population having a low risk profile for acquiring STIs. However, some other information obtained from the questionnaires gave some opposite evidence, which would alert us on the need of keeping watch, raising awareness and implementing preventive actions in this population.

    The examination of 216 donkeys presented for treatment at the Donkey Sanctuary-World Horse Welfare-Universidad Nacional Autonoma de Mexico mobile clinics revealed a number of health and welfare problems. A general overview of the donkeys' health was made and showed that the median body condition score (BCS) in this population was 2.5. Underweight animals only accounted for 26% of the population. Females, 0-5-year-olds and >21-year-olds, were more likely to be underweight. When analysed, there was no correlation between faecal worm egg count (FEC) and BCS. The prevalence of strongyle infection as assessed by FEC was shown to be 80% with a median FEC of 600 eggs per gramme. Donkeys were assessed for body lesions and showed a high prevalence (71%), particularly in the facial region (54%). Analysis showed that mature animals (6-15 years old) were at increased risk of body lesions compared to older animals (16+ years old) as were donkeys with dental disease and those in particular villages. Risk factor analysis for lesions of the face showed that stallions and geldings are at increased risk as were donkeys wearing halters made from nylon rope. This study has identified areas for further investigation and potential areas where targeted interventions may be made to improve the health and welfare of working donkeys in Mexico.

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.

    2014-01-01

    Biphosphonate-associated maxillary bone osteonecrosis (BPMO) is a complication related to nitrogen-containing biphosphonate therapy. This adverse effect occasionally appears in patients who are administered biphosphonates through intravenous infusion for the treatment of cancer involving bone metastases. It can also present, in a lesser degree, in patients who take these drugs orally for the treatment of osteoporosis. Lately, there has been an increase in the number of cases of osteopenia and osteoporosis due to the increasing life expectancy of the world’s population. In our country, a risk group composed mainly of older women who have been diagnosed with osteopenia or osteoporosis, and submitted to the continuous action of oral biphosphonates, is emerging. In this paper we present 18 cases of BPMO associated to the use of oral biphosphonates, diagnosed and treated in the Department of Stomatology of the School or Dentistry at Universidad Nacional de Rosario, Argentina. A protocol was designed in which the following information was recorded: age and sex of the patients, the original disease which led to therapy with oral biphosphonates, the drugs used and the period in which those drugs were administered, the clinical features and location of the lesions, together with triggering factors. Key words:Maxillary osteonecrosis, mandibular osteonecrosis, oral biphosphonates, alendronate, ibandronate. PMID:25674321

  19. Algorithms and physical parameters involved in the calculation of model stellar atmospheres

    NASA Astrophysics Data System (ADS)

    Merlo, D. C.

    This contribution summarizes the Doctoral Thesis presented at Facultad de Matemática, Astronomía y Física, Universidad Nacional de Córdoba for the degree of PhD in Astronomy. We analyze some algorithms and physical parameters involved in the calculation of model stellar atmospheres, such as atomic partition functions, functional relations connecting gaseous and electronic pressure, molecular formation, temperature distribution, chemical compositions, Gaunt factors, atomic cross-sections and scattering sources, as well as computational codes for calculating models. Special attention is paid to the integration of hydrostatic equation. We compare our results with those obtained by other authors, finding reasonable agreement. We make efforts on the implementation of methods that modify the originally adopted temperature distribution in the atmosphere, in order to obtain constant energy flux throughout. We find limitations and we correct numerical instabilities. We integrate the transfer equation solving directly the integral equation involving the source function. As a by-product, we calculate updated atomic partition functions of the light elements. Also, we discuss and enumerate carefully selected formulae for the monochromatic absorption and dispersion of some atomic and molecular species. Finally, we obtain a flexible code to calculate model stellar atmospheres.

    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.

    The ferroelectric response of bismuth titanate Bi4Ti3O12 (BIT) thin film is studied through a Monte Carlo simulation of hysteresis loops. The ferroelectric system is described by using a Diffour Hamiltonian with three terms: the electric field applied in the z direction, the nearest dipole-dipole interaction in the transversal (x-y) direction, and the nearest dipole-dipole interaction in the direction perpendicular to the thin film (the z axis). In the sample construction, we take into consideration the dipole orientations of the monoclinic and orthorhombic structures that can appear in BIT at low temperature in the ferroelectric state. The effects of temperature, stress, and the concentration of pinned dipole defects are assessed by using the hysteresis loops. The results indicate the changes in the hysteresis area with temperature and stress, and the asymmetric hysteresis loops exhibit evidence of the imprint failure mechanism with the emergence of pinned dipolar defects. The simulated shift in the hysteresis loops conforms to the experimental ferroelectric response.

    The effect of the bifurcation angle on the flow pattern developed during respiratory inhalation and exhalation processes was explored numerically using a synthetic model of lower human airways featuring three generations of a dichotomous morphology as described by a Weibel model. Laminar flow simulations were performed for six bifurcation angles and four Reynolds numbers relevant to human respiratory flow. Numerical results of the inhalation process showed a peak displacement trend of the velocity profile towards the inner walls of the model. This displacement exhibited correlation with Dean-type secondary flow patterns, as well as with the onset and location of vortices. High wall shear stress regions on the inner walls were observed for a range of bifurcation angles. Noteworthy, specific bifurcation angles produced higher values of pressure drop, compared to the average behavior, as well as changes in the volumetric flow through the branches. Results of the simulations for exhalation process showed a different picture, mainly the appearance of symmetrical velocity profiles and the change of location of the regions of high wall shear stress. The use of this modelling methodology for biomedical applications is discussed considering the validity of the obtained results.

    Over the years water sources have been contaminated with many chemical agents, becoming issues that affect health of the world population. The advances of the nanoscience and nanotechnology in the development new materials constitute an alternative for design molecular filters with great efficiencies and low cost for water treatment and purification. In the nanoscale, the process of filtration or separation of inorganic and organic pollutants from water requires to study interactions of these atoms or molecules with different nano-materials. Specifically, it is necessary to understand the role of these interactions in physical and chemical properties of the nano-materials. In this work, the main interest is to do a theoretical study of interaction between water molecules and 2D graphene-like systems, such as silicene (h-Si) or germanene (h-Ge). Using Density Functional Theory we calculate total energy curves as function of separation between of water molecules and 2D systems. Different spatial configurations of water molecules relative to 2D systems are considered. Structural relaxation effects and changes of electronic charge density also are reported.

    Feces of 798 male and female patients who attended the Parasitology Laboratory of the "Facultad de Ciencias Bioquímicas y Farmacéuticas de la Universidad Nacional de Rosario (República Argentina)" were examined. Out of the total number of samples, 281 were collected after a purgative, and 517 by serial collection. The samples were examined applying the routine parasitological analysis. Those which presented Blastocysts hominis were processed for their quantification and classification in different categories according to the number of cells per microscopic field with a magnification of 400 x. B. hominis appeared in 25.2% of the patients. Practically the same percentage was detected with either collection method. B. hominis was associated with other parasites, appearing as the only parasite in only 29.4% of the cases. Both its statistical association with the patient's age and its independence from sex were determined. The most frequent symptomatology in patients with B. hominis only was: abdominal pains, pruritus, flatulence, malaise, anorexia and diarrhea. Only 14.9% did not present any symptoms at all. The search for this protozoa should be a parasitological routine analysis since it is the cause of frequent intestinal disorders.

    2016-11-01

    In this work, 3D numerical simulations of an array of three normal circular synthetic jets embedded in an attached laminar boundary layer that separates under the influence of an inclined flap are performed for flow separation control. At the beginning of the present study, three cases are used to validate the numerical simulation with data obtained from experiments. The experimental data is chosen based on the cases which presented higher repeatability and reliability. Simulations showed reasonable agreement when compared with experiments. The simulations are undertaken at three synthetic jet operating conditions, i.e. Case A: L = 2, VR = 0.32; Case B: L = 4, VR = 0.64 and Case C: L = 6, VR = 0.96. The vortical structures produced for each synthetic jet operating condition are hairpin vortices for Case A and tilted vortices for Case B and C, respectively. By examining the spatial wall shear stress variations, the effect on the boundary layer prior to separation of the middle synthetic jet is evaluated. For effective flow control, produced at a relatively low the finding from this study suggests that hairpin vortical structures are more desirable structures. Universidad Nacional Autonoma de Mexico.

    We present a study on the effect of streamwise-travelling waves of spanwise wall velocity on the growth of near-wall turbulent streaks using a linearized formulation of the Navier-Stokes equations. The changes in streak amplification due to the travelling waves induced by the wall velocity are compared to published results of direct numerical simulation (DNS) predictions of the turbulent skin-friction reduction over a range of parameters; a clear correlation between these two sets of results is observed. Additional linearized simulations but at a much higher Reynolds numbers, more relevant to aerospace applications, produce results that show no marked differences to those obtained at low Reynolds number. It is also observed that a close correlation exists between DNS data of drag reduction and a very simple characteristic of the ``generalized'' Stokes layer generated by the streamwise-travelling waves.

    Although researchers have used drawings of the human figure to evaluate body-image in adults and children, test measures of the concepts involved have not been precisely constructed, so the purpose of this study was to estimate the body-image concept relations measured on the Goodenough-Harris Draw-a-Person Test and on the Prueba para Diagnóstico de Imagen Corporal--Universidad Nacional for 90 kindergarten, first and second graders. Factor analyses (sex by grade, 2 x 3; and sex by age, 2 x 7) showed that sex was not a significant factor on either measure, but grade and age were. A Pearson correlation for the total scores on both tests was a moderate, significant value of .45. Correlations of the total with subtest scores varied from .30 to .50. Values were strongest for first grade children from 6 to 6 1/2 yr. of age (.59 to .78), at the beginning of the developmental period in which children gradually gain an awareness of the parts of the body, their functions and left-right concepts.

    A description of the successful use of a fetal membrane in the recovery of a injured patient is presented. A diabetic female patient, 63 years old, was accidentally injured with a winnowing fork, which opened the skin of the front side of her left foot. For first two weeks, she was submitted to a treatment involving antibiotics, analgesics and antiinflammatories, but the infection did not disappear and the pain was almost unbearable. At the end of the third week, the injury underwent surgical washing with epidural blockage; suitable insulin dose and oral antidiabetics controlled the high-glucose concentration. However, due to the intensity of the pain, a risky epidural blockage was administered every four hours for 12 days. Finally, a radiosterilised human fetal membrane, which was collected at HCSAE and processed at ININ, was used as a biological wound dressing. Biological control of the tissue was performed at Facultad de Química de la Universidad Nacional Autónoma de México (The Chemistry Faculty of the National Autonomous University of Mexico) (UNAM). As a result, the pain first diminished and then stopped. The healing process started in a few days and led to a complete recovery in 2 1/2 months. At present, the patient is in good condition, living a normal life.

    A descriptive study of caries prevalence in peripheral urban and rural underprivileged groups was undertaken in self-selected populations demanding basic dental therapy in seven states of Mexico. Dental therapy services were delivered as part of a mobile oral health care program in the Mexican countryside implemented by the Dental School of Universidad Nacional Autónoma de México, during 1990 and 1991. Partial examination of clinical histories of 2,596 patients (mean age 21.8 years) revealed a mean DMFT (the sum of decayed, missing and filled teeth) of 9.21. Only 6.3 per cent of patients had DMFT = 0 and 10.7 per cent were caries-free. The largest component of DMFT were decayed teeth and the smallest one filled teeth. In general, results suggested that caries prevalence was high within the study populations, highlighting the little restorative treatment previously undertaken. The convenience of implementing oral health care schemes to deal with caries morbidity is discussed from the perspective of both the traditional dental treatment approach and preventive public health policies, taking into account the background of complex treatment needs present in these population groups.

    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.

    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

    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.

    The Telescopio San Pedro Martir (TSPM) is a new ground-based optical telescope project, with a 6.5 meters honeycomb primary mirror, to be built in the Observatorio Astronomico Nacional on the Sierra San Pedro Martir (OAN-SPM) located in Baja California, Mexico. The OAN-SPM has an altitude of 2830 meters above sea level; it is among the best location for astronomical observation in the world. It is located 1830 m higher than the atmospheric inversion layer with 70% of photometric nights, 80% of spectroscopic nights and a sky brightness up to 22 mag/arcsec2. The TSPM will be suitable for general science projects intended to improve the knowledge of the universe established on the Official Mexican Program for Science, Technology and Innovation 2014-2018. The telescope efforts are headed by two Mexican institutions in name of the Mexican astronomical community: the Universidad Nacional Autonoma de Mexico and the Instituto Nacional de Astrofisica, Optica y Electronica. The telescope has been financially supported mainly by the Consejo Nacional de Ciencia y Tecnologia (CONACYT). It is under development by Mexican scientists and engineers from the Center for Engineering and Industrial Development. This development is supported by a Mexican-American scientific cooperation, through a partnership with the University of Arizona (UA), and the Smithsonian Astrophysical Observatory (SAO). M3 Engineering and Technology Corporation in charge of enclosure and building design. The TSPM will be designed to allow flexibility and possible upgrades in order to maximize resources.

    The Peruvian Andes host about 71% of all tropical glaciers. Although several studies have focused on glaciers of the largest glaciered mountain range (Cordillera Blanca), other regions have received little attention to date. In 2011, a new program has been initiated with the aim of monitoring glaciers in the centre and south of Peru. The monitoring program is managed by the Servicio Nacional de Meteorología e Hidrología del Perú (SENAMHI) and it is a joint project together with the Universidad San Antonio Abad de Cusco (UNSAAC) and the Autoridad Nacional del Agua (ANA). In Southern Peru, the Quisoquipina glacier has been selected due to its representativeness for glaciers in the Cordillera Vilcanota considering area, length and orientation. The Cordillera Vilcanota is the second largest mountain range in Peru with a glaciated area of approximately 279 km2 in 2009. Melt water from glaciers in this region is partly used for hydropower in the dry season and for animal breeding during the entire year. Using Landsat 5 images, we could estimate that the area of Quisoquipina glacier has decreased by approximately 11% from 3.66 km2 in 1990 to 3.26 km2 in 2010. This strong decrease is comparable to observations of other tropical glaciers. In 2011, a meteorological station has been installed on the glacier at 5180 m asl., measuring air temperature, wind speed, relative humidity, net short and longwave radiation and atmospheric pressure. Here, we present a first analysis of air temperature and the radiation budget at the Quisoquipina glacier for the first three years of measurements. Additionally, we compare the results from Quisoquipina glacier to results obtained by the Institut de recherche pour le développement (IRD) for Zongo glacier (Bolivia) and Antizana glacier (Ecuador). For both, Quisoquipina and Zongo glacier, net shortwave radiation may be the most important energy source, thus indicating the important role of albedo in the energy balance of the glacier

    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 = http://www.fundacionsave.com/home_eng.html 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.

    Telescopio San Pedro Mártir (TSPM) project intends to build a 6.5 meters telescope with alt-azimuth design, currently at the conceptual design. The project is an association between Instituto de Astronomía de la Universidad Nacional Autónoma de México (IA-UNAM) and the Instituto Nacional de Astrofísica, Óptica Electrónica (INAOE) in partnership with department of Astronomy and Steward Observatory of University of Arizona and Smithsonian Astrophysical Observatory of Harvard University. Conceptual design of the telescope is lead and developed by the Centro de Ingeniería y Desarrollo Industrial (CIDESI). An overview of the feasibility study and the structural conceptual design are summarized in this paper. The telescope concept is based on telescopes already commissioned such as MMT and the Baade and Clay Magellan telescopes, building up on these proven concepts. The main differences relative to the Magellan pair are; the elevation axis is located 1 meter above the primary mirror vertex, allowing for a similar field of view at the Cassegrain and both Nasmyth focal stations; instead of using a vane ends to position the secondary mirror TSPM considers an Steward platform like MMT; finally TSPM has a larger floor distance to m1 cell than Magellans and MMT. Initially TSPM will operate with an f/5 Cassegrain station, but the design considers further Nasmyth configurations from a Cassegrain f/5 up to a Gregorian f/11. The telescope design includes 7 focal stations: 1 Cassegrain; 2 Nasmyth; and 4 folded-Cassegrain. The telescope will be designed and manufactured in Mexico, will be design in Queretaro by CIDESI and built between Queretaro and Michoacán manufacturing facilities; it will be preassembled in these facilities and disassembled to send it to the San Pedro Mártir Observatory for final integration. The azimuth and altitude structure is planned to be constructed in modules and transported by truck and shipped to Ensenada and finally to the OAN where is going

    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: http://sismicidad.ciens.ula.ve. 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: http://agata.ingeominas.gov.co:9090/SismicidadHistorica/. 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

    The Earth Hazards (EHaz) consortium consists of six research-based universities in the United States (Michigan Technological University, University at Buffalo), Canada (McGill University, Simon Fraser University) and México (Universidad Nacional Autónoma de México, Universidad de Colima) funded by the U.S. Department of Education, Human Resources and Skills Development Canada, and the Secretaría de Educación Pública of México, as part of the North American Free Trade Agreement. The objective of the consortium is to expose students to a wide variety of scientific and cultural perspectives in the mitigation of geological natural hazards in North America. This four year program is multi-faceted, including student exchanges, graduate level, web-based courses in volcanology, and intensive group field trips. In 2005 to 2006, a total of 27 students were mobilized among the three countries. In this first year, the videoconferencing course focused on caldera supervolcanoes with weekly discussion leaders from various fields of volcanology. At the end of the course the students participated in a field trip to Long Valley and Yellowstone calderas. Also during the first year of the program, México hosted an International Course on Volcanic Hazards Map Construction. The course was attended by graduate students from Mexico and the United States, included lectures from noted guest speakers, and involved a field trip to Popocatepetl volcano. A student survey demonstrated that during the videoconferencing the students benefited by the weekly interaction with well- known volcanologists at the top of their field. Students who participated in the field trip benefited from an outstanding opportunity to link the theoretical concepts covered during the course with the field aspects of supervolcano systems, as well as the opportunity to network amongst their peers. Feedback from students who went abroad indicates that the program provided support for internship opportunities

    Objetivo: El deterioro de los hábitos saludables en los jóvenes, particularmente universitarios, justifica su investigación en dichas poblaciones. El objetivo del presente estudio es analizar los niveles de actividad física en estudiantes de la Universidad Nacional de La Matanza (Argentina), intentando describir grupos homogéneos según características demográficas, de hábitos de salud y de percepción de bienestar, e identificando el nivel de actividad física que mejor describa a cada uno de los grupos. Metodología: Participaron 554 estudiantes (281 varones y 273 mujeres) de distintas carreras a los que se aplicó el Cuestionario Global de Actividad Física (GPAQ) y un instrumento sobre hábitos de salud, percepción de felicidad y diversas variables demográficas. Se calcularon medidas de tendencia central y variabilidad, así como los percentiles P25 y P75, para todas las variables. Se realizó una segmentación mediante análisis de clusters jerárquico, con un análisis de factores previo. Resultados: El 79,8% de los estudiantes, y el 97,2% de aquellos que cursaban Educación Física cumplían con las recomendaciones de realización de actividad física. Los alumnos que se identificaban con un nivel de actividad física alto eran los que cursaban en turno diurno, no consumían tabaco, alcohol ni drogas, no trabajaban, no tenían hijos ni pareja estable, y poseían un nivel socio- económico medio. Conclusiones: Se sugiere la necesidad de una sólida intervención educativa por parte de las universidades para fomentar hábitos saludables y la realización regular de actividad física, ya que tienen una responsabilidad social primaria respecto a estas problemáticas.

    The Cambumbia Stock is located on the western flank of the Central Cordillera of the northern Andes. The goals of this study were to petrographic and geochemically characterize the Cambumbia igneous body and to establish its petrogenetic history. 41 samples were collected, 28 for petrographic analysis and 14 for elementary chemical determination by ICP-MS. Petrographically the samples were classified as hornblende and pyroxene-gabbros varying to diorites, gabbronorites and tonalites, the rock texture varies from medium to coarse granular grain, with local microporfiritic texture. It was concluded from the major elements analysis that the samples correspond to the sub-alkaline series with low K content, mainly in the calc-alkaline series, within the gabbros and diorites fields. By using the SiO2 vs TiO2 (Jaramillo, 1980), Th/Yb vs Ta/Yb (Pearce, 1984) (Fig. 1) and Zr/117-Th-Nb/16 (Wood, 1979) diagrams it was determined that these rocks were generated in two geotectonic environments: one type MOR (extension) and other island arc (subduction, compression). Petrographic and geochemical comparisons between the rocks of Cambumbia Stock and Diorite and Gabbro El Pueblito (Giraldo, 2009) (located about 25 km to the north-west) may postulate a possible genetic link between them. Recently, a U/Pb age was obtained by the Universidad de Caldas in zircon in 2009 (not published data), yielded an age of 233.41 ± 3.4 Ma (Middle Triassic). This age is consistent with the global event of the extension and fragmentation of Pangea supercontinent. In addition, the mantle nature of the source and the petrogenetic evolution of the magmatic system were established.

    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

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

    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.
