    The LaRa experiment consists of a transponder onboard the ExoMars mission that has been designed to obtain two-way Doppler shift measurements from a X-band radiolink between the lander on Mars and the ground stations on Earth. LaRa is planned to last at least one Earth year and should begin to operate from January 2021. RISE is another transponder onboard the InSight mission. This NASA experiment should last at least one Martian year starting from November 2018. The Doppler measurements are used to obtain the Mars' orientation and rotation parameters (MOP) i.e. the length-of-day (LOD) variations, the precession rate and the nutations of the rotation axis, and the polar motion. One of the major objectives of LaRa is to improve our knowledge of the deep interior of Mars by precisely measuring the signature of the liquid core in the nutations. In this study, we performed numerical simulations of these Doppler measurements in order to evaluate the impact on the determination of the MOP and the gain in precision provided by the synergy between both LaRa and RISE experiments. We used the GINS (Géodésie par Intégrations Numériques Simultanées) software implemented by the CNES and further developed at ROB for planetary geodesy applications. We assess the advantage of having the LaRa experiment in a row or at the same time as RISE experiment by considering the following scenarios for comparison: RISE and LaRa alone, RISE followed by LaRa, LaRa together with RISE. In this way, we study the impact of an improved Doppler geometry induced by the involvement of two landers instead of one. The Doppler geometry is a fundamental aspect of radioscience experiments. It affects the measurement sensitivity to the MOP and is thereby an important factor in their determination. The variety of the geometry (especially the azimuth) provided by its omnidirectional patch antenna is a strength of LaRa compared to RISE (two directional horn antennas) that allows to improve the MOP

    The LaRa (Lander Radioscience) experiment is designed to obtain coherent two-way Doppler measurements from the radio link between the ExoMars lander and Earth over at least one Martian year. The instrument life time is thus almost twice the one Earth year of nominal mission duration. The Doppler measurements will be used to observe the orientation and rotation of Mars in space (precession, nutations, and length-of-day variations), as well as polar motion. The ultimate objective is to obtain information / constraints on the Martian interior, and on the sublimation / condensation cycle of atmospheric CO2. Rotational variations will allow us to constrain the moment of inertia of the entire planet, including its mantle and core, the moment of inertia of the core, and seasonal mass transfer between the atmosphere and the ice caps. The LaRa experiment will be combined with other ExoMars experiments, in order to retrieve a maximum amount of information on the interior of Mars. Specifically, combining LaRa's Doppler measurements with similar data from the Viking landers, Mars Pathfinder, Mars Exploration Rovers landers, and the forthcoming InSight-RISE lander missions, will allow us to improve our knowledge on the interior of Mars with unprecedented accuracy, hereby providing crucial information on the formation and evolution of the red planet.

    Helicobacter pylori, one of the most prevalent human pathogens, is associated with chronic gastritis, peptic ulcer disease, and possibly gastric cancer and primary gastric lymphoma. The need to treat these patients has necessitated the development of improved methods to diagnose H. pylori infection. We present the preliminary assessment of a 13C-urea breath test (UBT) in which the expired 13CO2 is detected in a rapid, simple, inexpensive way by the LARA (Laser Assisted Ratio Analyzer) System (Alimenterics, Inc., Morris Plains, NJ). Eighty-seven consecutive patients, examined for upper gastrointestinal symptoms, underwent endoscopy. H. pylori infection was established by antral biopsies and a rapid urease test (CLOtest). The UBT was performed between 2 and 24 hours after endoscopy. Of the 84 analyzable patients, 70 were found to be H. pylori-positive either by histology or by CLOtest. All 70 were positive by the LARA UBT, yielding a sensitivity of 100%. Fourteen patients were negative for H. pylori by histology and the CLOtest. Of these, 12 were negative by the LARA UBT and 2 were positive, yielding a specificity of 85.7%; because of the limitations of H. pylori detection by histology or urease assays, however, the specificity of the UBT may have been underestimated. Our study demonstrates the feasibility of a nonradioactive, rapid UBT based on the LARA system and suggests the need for its more detailed evaluation.

    The LaRa (Lander Radioscience) experiment is designed to obtain coherent two-way Doppler measurements from the radio link between the 2020 ExoMars lander and Earth over at least one Martian year. The LaRa instrument consists of a coherent transponder with up- and downlinks at X-band radio frequencies. The signal received from Earth is a pure carrier at 7.178 GHz; it is transponded back to Earth at a frequency of 8.434 GHz. The transponder is designed to maintain its lock and coherency over its planed one-hour observation sessions. The transponder mass is at the one-kg level. There are one uplink antenna and two downlink antennas. They are small patch antennas covered by a radome of 130gr for the downlink ones and of 200gr for the uplink. The signals will be generated and received by Earth-based radio antennas belonging to the NASA deep space network (DSN), the ESA tracking station network, or the Russian ground stations network. The instrument lifetime is more than twice the nominal mission duration of one Earth year. The Doppler measurements will be used to observe the orientation and rotation of Mars in space (precession, nutations, and length-of-day variations), as well as polar motion. The ultimate objective is to obtain information/constraints on the Martian interior, and on the sublimation/condensation cycle of atmospheric CO2. Orientation and rotational variations will allow us to constrain the moment of inertia of the entire planet, the moment of inertia of the core, and seasonal mass transfer between the atmosphere and the ice caps. The LaRa experiment will be combined with other previous radio science experiments such as the InSight (Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) RISE experiment (Rotation and Interior Structure Experiment) with radio science data of the NASA Viking landers, Mars Pathfinder and Mars Exploration Rovers. In addition, other ExoMars2020 and TGO (Trace Gas Orbiter) experiments providing

    2011-01-01

    Background Violence by young people is one of the most visible forms of violence and contributes greatly to the global burden of premature death, injury and disability. Methods The Global School-based Student Health Survey (GSHS), State of Lara, Venezuela (GSHS-Lara) is a school-based surveillance system. It comprises a repeated, cross-sectional, self-administered survey drawn from a representative sample of 7th to 9th grade students, performed in the school years 2003-2004 (GSHS-Lara 2004) and 2007-2008 (GSHS-Lara 2008). It explores, among other things, a general violence indicator such as school absenteeism due to feeling unsafe at school or on the way to or from school for any reason; and more specific indicators of violence such as robbery, bullying, physical fights and use of weapons, as well as exposure to lectures on how to prevent violence. Results are given in terms of prevalence percentage. Results Absenteeism doubled between the two study periods (10.8% to 20.8%). The number of students that were a victim of robbery remained high and without change both outside (14.2% and 14.8%) and inside school (21.7% and 22.0%). The number of victims of bullying was high and increasing (33.4% and 43.6%). Bullying associated with being physically attacked decreased (18.5% to 14.3%). Physical attacks without active participation and not associated with bullying were frequent (21.5%). Physical fighting with active participation prevalence remained high and without change (27.5% and 28.2%). Carrying a weapon almost doubled (4.3% to 7.1%). Less than 65% reported classes for violence prevention. Conclusions The GSHS-Lara shows that violence is an important public health problem that needs to be addressed by the community and its authorities. PMID:22958602

  12. Conversation with Lara about the Earth and Land. (Spanish Title: Conversando con Lara sobre la Tierra y la Teirra.) Conversando com Lara sobre a Terra e a Terra

    The present article is the analysis of a conversation between the author and Lara, a four-yearold- girl, enrolled in nursery school, while she makes a drawing of the Earth. It took place outside school environment and without any other person around to avoid interference during the interview. According to Ferreira & Silva (2004), a researcher can only comprehend a child's drawing, or form, by listening to him/her while he/she is creating it. Lara presented the traditional flat drawing, picturing the sky parallel to the ground, as reported by Nardi & Carvalho (1996). However, when asked to draw the World - term used by Butterworth et al. (2002), in order to avoid unnecessary confusion - she represented it by a circle, with herself on the surface. Her drawings led to the conclusion that such girl does not know yet the World in which she lives is the Earth, and probably because of that, within her age and consequent maturity, she accurately differentiates the concepts of land and Earth. El presente artículo analiza una entrevista libre, mientras una niña de 4 años y 4 meses, matriculada en el pregrado, dibuja la Tierra. Esta entrevista se realizó fuera del ambiente escolar y sin otra persona alrededor que pudiera interferir. De acuerdo con Ferreira Silva (2004), para quien investiga es posible conocer realmente lo que un niño o una niña pone en el papel a través de grafismos y/o dibujos si se lo escucha durante el proceso de creación de la escritura con imágenes. La niña, en este caso, representa la Tierra con el tradicional dibujo plano y el "cielo" paralelo al suelo, conforme analizaron Nardi & Carvalho (1996). Pero, cuando se Le solicita dibujar el "Mundo" - palabra empleada en un trabajo de Butterworth et al. (2002), con intención de no provocar "confusiones" innecesarias a sus sujetos de investigación- lo representa de forma circular, poniéndose sobre su superficie. Sus dibujos llevan a concluir que esta niña aún no tiene conocimiento que el mundo

    This study was carried out to compare the measurements and the diagnostic accuracy of the traditional expensive IRMS and the new economical LARA system using two doses of [13C]urea + two different test meals in patients undergoing upper gastrointestinal endoscopy, both before and after anti-Helicobacter treatment. A total of 354 dyspeptic patients underwent endoscopy with gastric biopsies to diagnose H. pylori infection by CLO-test and histology. No patients had taken antibiotics, bismuth, or antisecretory drugs in the 4 weeks before testing. After overnight fasting, breath samples were collected simultaneously in both plastic and glass tubes at baseline and at 30 and 60 min after urea ingestion. In 237 patients 100 mg [13C]urea + Ensure and in 117 patients 75 mg [13C]urea + citric acid were given. The test was also performed with the two urea dosages and meals in 67 and 64 infected patients, respectively, four weeks after anti-Helicobacter therapy. H. pylori was considered eradicated when both biopsy-based tests were negative. A delta value >5 per thousand was considered positive. Breath samples with insufficient CO2 levels at both 30 and 60 min were excluded from final analysis (N = 37 in pre- and N = 8 in posttreatment). There was excellent agreement between overall delta values of the two machines with both [13C]urea 100 mg + Ensure and [13C]urea 75 mg + citric acid. The 95% CI of the difference against the mean was wider with the former (mean -1.3, +6.3, and -9.4) than with the latter urea dosage and test meal (mean -1.2, +5.2 and -8.1). LARA and IRMS were equally effective (P = NS) in distinguishing infected from uninfected patients before therapy using both doses of [13C]urea and test meals (sensitivity ranged from 95% to 99% and specificity from 95% to 97%). This good performance was maintained in the posttreatment phase (sensitivity ranged from 90% to 100% and specificity from 90% to 97%), without any statistical difference among the various combinations

    The increasing interest for the environmental problems and the study of the impact on the environment due to antropic activity produced an enhancement of remote sensing applications. The Italian National Research Council (CNR) established a new laboratory for airborne hyperspectral imaging, the LARA Project (Laboratorio Aero per Ricerche Ambientali - Airborne Laboratory for Environmental Research), equipping its airborne laboratory, a CASA-212, mainly with the Daedalus AA5000 MIVIS (Multispectral Infrared and Visible Imaging Spectrometer) instrument. MIVIS's channels, spectral bandwidths, and locations are chosen to meet the needs of scientific research for advanced applications of remote sensing data. MIVIS can make significant contributions to solving problems in many diverse areas such as geologic exploration, land use studies, mineralogy, agricultural crop studies, energy loss analysis, pollution assessment, volcanology, forest fire management and others. The broad spectral range and the many discrete narrow channels of MIVIS provide a fine quantization of spectral information that permits accurate definition of absorption features from a variety of materials, allowing the extraction of chemical and physical information of our environment. The availability of such a hyperspectral imager, that will operate mainly in the Mediterranean area, at the present represents a unique opportunity for those who are involved in environmental studies and land-management to collect systematically large-scale and high spectral-spatial resolution data of this part of the world. Nevertheless, MIVIS deployments will touch other parts of the world, where a major interest from the international scientific community is present.

    An animated film has been created to provide information to women requesting early medical abortion (EMA). The 9 min film, Lara's Story , was created using one woman's personal account of her experience. This study evaluated the views of women who had recently undergone EMA on the film and its potential usefulness in providing experiential information to women requesting EMA. Women who had undergone EMA within the past month were recruited. They were shown the film and interviewed in a semi-structured style. Interviews were recorded and transcribed verbatim. They were analysed using cross-sectional indexing and thematic analysis with an inductive approach. 13 women were interviewed. All reported that the film gave a realistic account of EMA and most agreed that they would have wanted to watch it before EMA had it been available. Some said that it might help women who were struggling with decision-making with regard to EMA and all said that there should be unrestricted access to the film from the website of the abortion service. The women commented that the animated style of the film allowed all groups of women to relate to the story. Some commented that Lara's experience of pain, bleeding and side effects such as nausea differed from their own and therefore felt that it would be useful to make more than one woman's account available. The availability of animated audiovisual films recounting women's experiences of EMA might be a valuable adjunct to clinical information for women seeking EMA. © Faculty of Sexual and Reproductive Healthcare of the Royal College of Obstetricians and Gynaecologists (unless otherwise stated in the text of the article) 2017.

    A molecular epidemiological study was performed using FTA card materials directly sampled from lesions of patients with cutaneous leishmaniasis (CL) in the state of Lara, Venezuela, where causative agents have been identified as Leishmania (Viannia) braziliensis and L. (Leishmania) venezuelensis in previous studies. Of the 17 patients diagnosed with CL, Leishmania spp. were successfully identified in 16 patients based on analysis of the cytochrome b gene and rRNA internal transcribed spacer sequences. Consistent with previous findings, seven of the patients were infected with L. (V.) braziliensis. However, parasites from the other nine patients were genetically identified as L. (L.) mexicana, which differed from results of previous enzymatic and antigenic analyses. These results strongly suggest that L. (L.) venezuelensis is a variant of L. (L.) mexicana and that the classification of L. (L.) venezuelensis should be reconsidered. Copyright © 2011 Royal Society of Tropical Medicine and Hygiene. Published by Elsevier Ltd.

    This report summarizes the data available on radioactive source materials in Los Estados Unidos de Venezuela accumulated by geologists of the Direccions Tecnica de Geolgia and antecedent agencies prior to June 1951, and the writers from June to November 1951. The investigation comprised preliminary study, field examination, office studies, and the preparation of this report, in which the areas and localities examined are described in detail, the uranium potentialities of Venezuela are summarized, and recommendations are made. Preliminary study was made to select areas and rock types that were known or reported to be radioactive or that geologic experience suggests would be favorable host for uranium deposits, In the office, a study of gamma-ray well logs was started as one means of amassing general radiometric data and of rapidly scanning many of ye rocks in northern Venezuela; gamma-ray logs from about 140 representative wells were examined and their peaks of gamma intensity evaluated; in addition samples were analyzed radiometrically, and petrographically. Radiometic reconnaissance was made in the field during about 3 months of 1951, or about 12 areas, including over 100 localities in the State of Miranda, Carabobo, Yaracuy, Falcon, Lara, Trujillo, Zulia, Merida, Tachira, Bolivar, and Territory Delta Amacuro. During the course of the investigation, both in the filed and office, information was given about geology of uranium deposits, and in techniques used in prospecting and analysis. All studies and this report are designed to supplement and to strengthen the Direccion Tecnica de Geologias's program of investigation of radioactive source in Venezuela now in progress. The uranium potentialities of Los Estados de Venezuela are excellent for large, low-grade deposits of uraniferous phospahtic shales containing from 0.002 to 0.027 percent uranium; fair, for small or moderate-sized, low-grade placer deposits of thorium, rare-earth, and uranium minerals; poor, for

    Suicidal behavior among adolescents is not a well-explored public health problem. Health policy decision-making on suicidal behavior needs reliable information on the prevalence of suicidal ideation (SI) and its associated risk factors to produce health promotion and prevention programs. The Global School Health Survey is a self-administered survey done on a random probabilistic sample among students of the 7th, 8th, and 9th grades in the Lara State, Venezuela, school period 2003 to 2004. Point prevalence of SI and associated factors were included and the odds (OR) of having SI was calculated given selected factors. Two-thousand seventy (2070) respondents, of which 13.5 % reported having SI in the last 12 months, and in females more than males (14.6% vs. 11.7%). The OR for SI, according to an associated risk factor, were among (a) females: age > or = 14 years (2.2), worries (3.42), loneliness (8.8), ever had sexual intercourse (5.58), alcohol (8.43) and (b) males: having only one or non close friends (3.69), alcohol (12.36), ever had sexual intercourse (2.73). Behavioral risk factors are relatively new in the field of surveillance systems; therefore, results on SI should be cautiously taken into consideration and a wide discussion should be encouraged as we learn how to best use the results for health promotion and disease prevention.

    Effective sexual health promotion programs need to be based on evidence; this study describes a set of sexual behavioral patterns, education and other subjects related to sexual life among 71th, 8th and 9th grade students in the State of Lara, Venezuela. During 2003 to 2004 school period, 2070 students filled out the Global School Health Survey (GSHS)--a school based cross-sectional self-administered survey that explores, among other areas, sexual behavior. Students who responded that ever had intercourse, males 27% and females 3.8%; by grade, males 18.2% (7th) and 37.6 % (9th), and females 1.9% (7th) and 6.2% (9th). The group who had intercourse, 54.9% males and 25.3% females had it by age 12; 59% males and 78.6% females were sexually active in the past 12 months; 59.2% males and 43.2% females used condom in the last intercourse; and 48.3% males and 21.5% females has 2 or more sexual partners in their life. A disparity is present in school-based information, >63% for AIDS and <32% for sexual abuse. This study shows that a substantial number of students had sexual intercourse initiation at early age (<12), history of multiple sexual partners and low prevalence of condom use. An unbalanced coverage of information on AIDS and sexual abuse is highly prevalent in the school. However, the implementation and evaluation of comprehensive programs on healthy sexual life must take into account that still a majority of students report abstinence from sexual intercourse.

The LaRA Group undertook to assess whether the law fully safeguards the health and safety of both workers and third parties, without impinging upon the civil rights of workers. A written document expressing agreement was produced following discussions between doctors, lawyers, bioethicists and social partners. There are gaps and inconsistencies in current laws; the differences in local and regional provisions prevent authorities from applying a single strategy at national level. There should be a change in existing rules under which the employer's obligation to enforce the ban on consumption alcohol in the workplace is enacted solely by the "competent" physician whose institutional role is to safeguard and promote health. Some occupational categories that are subject to a ban on alcohol consumption do not currently under-go health surveillance. For example, if road transport drivers are not exposed to a specific occupational risk foreseen under another law, they can be placed under health surveillance only in those regions where the local laws contemplate this type of control. In other cases, the practice of assessing the risk to third parties and providing for compulsory health surveillance in the Risk Assessment Document, is considered by some jurists to be a "consuetudo praeter legem" and therefore acceptable in a field not yet covered by a specific law, but to be "contra legem" or unlawful by other jurists. Moreover, the competent physician who uses a breathanalyser or tests for alcohol addiction faces an ethical dilemma, since by communicating the results to an employer or authorities responsible for the issuing of licenses, he may be violating his professional oath of secrecy. Furthermore, the emphasis placed on testing has induced companies and inspectors to

    Stroke, the 5th. cause of death in Venezuela, has been associated to cerebral infarction. However, there is little information concerning lethality factors. 33 atherothrombotic subtype stroke patients, 31 (96%) Latino and 2(4%) white, were admitted into a prospective study to analyze the role of 11 mortality risk factors for those patients. A mortality relative risk (RR) > 1.5 or < 1 (protective) was considered clinically important if 1 was excluded from the 95% confidence interval (95%CI). The Mantel-Haenszel Chi-square procedure was use to test statistical significance (p < 0.05). Mortality RR for patients age 65 and over (RR = 2.95) and 4 year mortality RR for male patients (RR = 2.04) were clinically and statistically significant. History of high blood pressure was protective (RR = 0.62) probably due to good medical control. Cumulative mortality was higher than that of comparable studies, even from the first week of follow-up, reaching 67% at the 4th year.

    Resumen A finales de la década de los cincuenta, Estados Unidos permitía la entrada de aproximadamente medio millón de inmigrantes mexicanos al año, de los cuales 450.000 entraban con visados de trabajo temporal y 50.000 llegaban con visados de residentes permanentes. A mediados de los años sesenta, los cambios en la política migratoria de Estados Unidos realizados en nombre de los derechos civiles redujeron drásticamente las oportunidades de entrada legal a Estados Unidos. Se eliminaron los visados de trabajo temporal y se limitaron los visados de residentes a 20.000 por año. Con las oportunidades de entrada legal restringidas, los flujos migratorios ya establecidos simplemente continuaron, fuera de los límites legales, dando comienzo a una inesperada reacción en cadena de eventos que culminaron en una guerra total contra los inmigrantes y el rápido crecimiento -sin precedentes- de población residente no autorizada en Estados Unidos. El presente artículo demuestra que el aumento de inmigración indocumentada en los Estados Unidos y el crecimiento de la población sin papeles son un producto de políticas migratorias y fronterizas mal concebidas.

    The expedition in November-December 2005 to Isla de los Estados (Staten Island) off the southeastern tip of South America was a cooperative venture between Lund University (LU) and Stockholm University (SU) in Sweden and the CADIC-CONICET Institute in Ushuaia, Argentina. The aim of the expedition was threefold: (1) to extend the Swedish paleoclimatic "ATLANTIS"-project (Greenland, Iceland, Faroe Islands, Azores, Grenada, Tristan da Cunha; PI S Björck) to the southern part of the South American continent, (2) to connect earlier glacial and climate history reconstructions from the Antarctic Peninsula to equivalents north of the Drake Passage in southernmost South America, and (3) to complement paleo-information available from the Tierra del Fuego mainland with information from Isla de los Estados. Focus was on two areas in the northern and north-western part of the island, Bahía Colnett and Bahia Crossley. Detailed geomorphologic and stratigraphic mapping of glacial deposits were combined with sampling sediments for OSL dating. To reconstruct the paleoclimatic development of Isla de los Estados since the last ice retreat, four main peat bog/lake sites were cored and sampled. In addition, living trees of Nothofagus and old logs preserved in the peat were sampled for dendrochronological and dendroclimatological studies. Preliminary results show that the deglaciation of the study area occurred before 16500 cal yr BP. Detailed multi- proxy analyses of the four sequences are under way and first results will be presented.

    Chagas disease is a neglected public health problem in Mexico; however, detailed studies to determine the seroprevalence in some states have not been performed. A total 1,504 human serum from thirteen communities in Estado de Mexico, were analyzed with three diagnostics techniques. The overall seroprevalence was 9.1%, with high prevalence among people aged 51-60 years, while people aged 0-29 years were seronegative against T. cruzi. Our data demonstrated the seroprevalence of T. cruzi in the North of the Estado de Mexico, an area considered as non-endemic; however, epidemiological conditions necessary for natural transmission were found.

    There is a continuous and increasing demand for solutions, both software and hardware-based, that are able to productively handle underground utilities geospatial data. Innovative approaches that are based on the use of the European GNSS, Galileo and EGNOS, sensor technologies and LBS, are able to monitor, document and manage utility infrastructures' data with an intuitive 3D augmented visualisation and navigation/positioning technology. A software and hardware-based system called LARA, currently under develop- ment through a H2020 co-funded project, aims at meeting that demand. The concept of LARA is to integrate the different innovative components of existing technologies in order to design and develop an integrated navigation/positioning and information system which coordinates GNSS, AR, 3D GIS and geodatabases on a mobile platform for monitoring, documenting and managing utility infrastruc- tures on-site. The LARA system will guide utility field workers to locate the working area by helping them see beneath the ground, rendering the complexity of the 3D models of the underground grid such as water, gas and electricity. The capacity and benefits of LARA are scheduled to be tested in two case studies located in Greece and the United Kingdom with various underground utilities. The paper aspires to present the first results from this initiative. The project leading to this application has received funding from the European GNSS Agency under the European Union's Horizon 2020 research and innovation programme under grant agreement No 641460.

  12. Petrogenesis of fertile mantle peridotites from the Monte del Estado massif (southwest Puerto Rico): a preserved section of Proto-Caribbean oceanic lithospheric mantle?

    The Monte del Estado massif is the largest and northernmost serpentinized peridotite belt in southwest Puerto Rico. It is mainly composed of spinel lherzolite and minor harzburgite with variable clinopyroxene modal abundances. Mineral and whole rock major and trace element compositions of peridotites coincide with those of fertile abyssal peridotites from mid ocean ridges. Peridotites lost 2-14 wt% of relative MgO and variable amounts of CaO by serpentinization and seafloor weathering. HREE contents in whole rock indicate that the Monte del Estado peridotites are residues after low to moderate degrees (2-15%) of fractional partial melting in the spinel stability field. However, very low LREE/HREE and MREE/HREE in clinopyroxene cannot be explained by melting models of a spinel lherzolite source and support that the Monte del Estado peridotites experienced initial low fractional melting degrees (~ 4%) in the garnet stability field. The relative enrichment of LREE in whole rock is not due to secondary processes but probably reflects the capture of percolating melt fractions along grain boundaries or as microinclusions in minerals, or the presence of exotic micro-phases in the mineral assemblage. We propose that the Monte del Estado peridotite belt represents a section of ancient Proto-Caribbean (Atlantic) lithospheric mantle originated by seafloor spreading between North and South America in the Late Jurassic-Early Cretaceous. This portion of oceanic lithospheric mantle was subsequently trapped in the forearc region of the Greater Antilles paleo-island arc generated by the northward subduction of the Caribbean plate beneath the Proto-Caribbean ocean. Finally, the Monte del Estado peridotites belt was emplaced in the Early Cretaceous probably as result of the change in subduction polarity of the Greater Antilles paleo-island arc without having been significantly modified by subduction processes.

    ABSTRACT The yucca moths (Tegeticula and Parategeticula; Lepidoptera, Prodoxidae) are well-known for their obligate relationship as exclusive pollinators of yuccas. Revisionary work in recent years has revealed far higher species diversity than historically recognized, increasing the number of described species from four to 21. Based on field surveys in Mexico and examination of collections, we describe five additional species: T. californica Pellmyr sp. nov., T. tehuacana Pellmyr & Balcázar-Lara sp. nov., T. tambasi Pellmyr & Balcázar-Lara sp. nov., T. baja Pellmyr & Balcázar-Lara sp. nov., and P. californica Pellmyr & Balcázar-Lara sp. nov. Tegeticula treculeanella Pellmyr is identified as amore » junior synonym of T. mexicana Bastida. A diagnostic key to the adults of all species of the T. yuccasella complex is provided. A phylogeny based on a 2104-bp segment of mitochondrial DNA (mtDNA) in the cytochrome oxidase I and II region supported monophyly of the two pollinator genera, and strongly supported monophyly of the 17 recognized species of the T. yuccasella complex. Most relationships are well-supported, but some relationships within a recent and rapidly diversified group of 11 taxa are less robust, and in one case conflicts with a whole-genome data set (AFLP). The current mtDNA-based analyses, together with previously published AFLP data, provide a robust phylogenetic foundation for future studies of life history evolution and host interactions in one of the classical models of coevolution and obligate mutualism.

  15. Lactate Racemase Nickel-Pincer Cofactor Operates by a Proton-Coupled Hydride Transfer Mechanism.

    Lactate racemase (LarA) of Lactobacillus plantarum contains a novel organometallic cofactor with nickel coordinated to a covalently tethered pincer ligand, pyridinium-3-thioamide-5-thiocarboxylic acid mononucleotide, but its function in the enzyme mechanism has not been elucidated. This study presents direct evidence that the nickel-pincer cofactor facilitates a proton-coupled hydride transfer (PCHT) mechanism during LarA-catalyzed lactate racemization. No signal was detected by electron paramagnetic resonance spectroscopy for LarA in the absence or presence of substrate, consistent with a +2 metal oxidation state and inconsistent with a previously proposed proton-coupled electron transfer mechanism. Pyruvate, the predicted intermediate for a PCHT mechanism, was observed in quenched solutions of LarA. A normal substrate kinetic isotope effect ( k H / k D of 3.11 ± 0.17) was established using 2-α- 2 H-lactate, further supporting a PCHT mechanism. UV-visible spectroscopy revealed a lactate-induced perturbation of the cofactor spectrum, notably increasing the absorbance at 340 nm, and demonstrated an interaction of the cofactor with the inhibitor sulfite. A crystal structure of LarA provided greater resolution (2.4 Å) than previously reported and revealed sulfite binding to the pyridinium C4 atom of the reduced pincer cofactor, mimicking hydride reduction during a PCHT catalytic cycle. Finally, computational modeling supports hydride transfer to the cofactor at the C4 position or to the nickel atom, but with formation of a nickel-hydride species requiring dissociation of the His200 metal ligand. In aggregate, these studies provide compelling evidence that the nickel-pincer cofactor acts by a PCHT mechanism.

    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.

    Potato is an important vegetable; however, salt stress drastically affects its growth and yield. A pot experiment was therefore conducted to assess salicylic acid efficacy in improving performance of potato cultivars, grown under salt stress (50 mmol L -1 ). Salicylic acid at 0.5 mmol L -1 was sprayed on to potato plants after 1 week of salinity application. Salt stress effects were ameliorated by salicylic acid effectively in both the studied cultivars. N-Y LARA proved more responsive to salicylic acid application than 720-110 NARC, which confirmed genetic variation between cultivars. Salicylic acid scavenged reactive oxygen species by improving antioxidant enzyme activities (superoxide dismutase, catalase, peroxidases) and regulating osmotic adjustment (proline, phenolic contents), which led to enhanced water relation and gaseous exchange attributes, and thereby increased potassium availability and reduced sodium content in potato leaves. Moreover, potato tuber yield showed a positive correlation with potassium content, photosynthesis and antioxidant enzyme activities. Salt tolerance efficacy of salicylic acid is authenticated in improving potato crop performance under salt stress. Salicylic acid effect was more pronounced in N-Y LARA, reflecting greater tolerance than 720-110 NARC, which was confirmed as a susceptible cultivar. Hence salicylic acid at 0.5 mmol L -1 and cultivation of N-Y LARA may be recommended in saline soil. © 2016 Society of Chemical Industry. © 2016 Society of Chemical Industry.

    La historia de la migración México-Estados Unidos se caracteriza por una serie de periodos durante los cuales los patrones migratorios se transforman y evolucionan como respuesta a los cambios en la política migratoria de Estados Unidos. En la década de 1990 se dio uno de estos cambios, lo que provocó el paso de la ‘era de la contradicción’ a la ‘era de la marginalización’. Actualmente, un gran número de migrantes indocumentados permanecen al margen de la ley, precisamente en un periodo en el que las penas se han incrementado y la persecución ha alcanzado niveles récord. De manera cada vez más notoria, los migrantes indocumentados, por la represión interna y fronteriza, quedan obligados a romper los lazos que los vinculaban con sus lugares de destino, pero al mismo tiempo se sienten cada vez más extraños en una tierra donde la aplicación de políticas antiinmigrantes es cosa de todos los días, lo que los sitúa en una posición de marginalización y gran vulnerabilidad.

    In volcanic terrains, dormant stratovolcanoes are very common and can trigger landslides and debris flows continually along stream systems, thereby affecting human settlements and economic activities. It is important to assess their potential impact and damage through the use of landslide inventory maps and landslide models. This poster provides an overview of the on-going research project (Grant SEP-CONACYT no 167495) from the Institute of Geography at the National Autonomous University of Mexico (UNAM) that seeks to conduct a multi-temporal landslide inventory and produce a landslide susceptibility map by using Geographic Information Systems (GIS). The Río El Estado watershed on the southwestern flank of Pico de Orizaba volcano, the highest mountain in Mexico, is selected as a study area. The catchment covers 5.2 km2 with elevations ranging from 2676.79 to 4248.2 m a.s.l. and hillslopes between 5° and 56°. The stream system of Río El Estado catchment erodes Tertiary and Quaternary lavas, pyroclastic flows, and fall deposits. The geologic and geomorphologic factors in combination with high seasonal precipitation, high degree of weathering, and steep slopes predispose the study area to landslides. The method encompasses two main levels of analysis to assess landslide susceptibility. The first level builds a historic landslide inventory. In the study area, an inventory of more than 100 landslides was mapped from interpretation of multi-temporal aerial orthophotographs and local field surveys to assess and describe landslide distribution. All landslides were digitized into a GIS, and the spatial geo-database of landslides was constructed from standardized GIS datasets. The second level calculates the susceptibility for the watershed. Multiple Logistic Regression (MLR) was used to examine the relationship between landsliding and several independent variables (elevation, slope, terrain curvature, flow direction, saturation, contributing area, land use, and geology

    The article explores the emergence of an architectural heritage in the realm of healthcare assistance for workers in the sugarcane agroindustry in Brazil following enactment of the law known as the Estatuto da Lavoura Canavieira (1941), under the auspices of the Instituto do Açúcar e do Álcool and as part of Estado Novo policies (1937-1945). The institute proposed solutions based on surveys conducted at sugarcane mills in cane-producing states and on the medical and hospital system adopted by the institute's enlightened bureaucracy in the 1940s, which took the U.S. system as its model. Special focus is given to the central hospitals in Pernambuco and especially in Alagoas, which opposed institute guidelines.

    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.

    Rosado Olivieri, Wilda Y.

    Gran parte de la investigacion acerca de la ensenanza de las ciencias se dedica a estudiar la forma o manera en que los estudiantes visualizan los conceptos cientificos. Para Driver (1983) esas ideas o concepciones se conocen como concepciones alternativas; las cuales pueden ocasionar dificultad para comprender los conceptos de las diferentes areas del conocimiento. El proposito de este estudio fue: (a) indagar como las distintas etapas del ABP permiten explorar las concepciones alternativas que poseen los estudiantes de nivel elemental acerca de los estados de agregacion de la materia y, (b) explorar en que medida el ABP permite identificar e incorporar las concepciones alternativas que poseen los estudiantes de nivel elemental con relacion al concepto de estados de agregacion de la materia para facilitar su aprendizaje. Con el fin de explorar las concepciones alternativas en el tema de los estados agregados de la materia se implanto la estrategia de Aprendizaje Basado en Problemas (ABP) con estudiantes de quinto grado de nivel elemental. Se utilizo la metodologia mixta con varias estrategias de recopilacion de datos, como una pre y pos prueba para elucidar el conocimiento previo y al mismo tiempo las concepciones alternativas sobre el tema bajo estudio y luego verificar el aprendizaje en los estudiantes. Asimismo, el uso de mapas conceptuales para determinar la profundidad del tema estudiado y el entrelazamiento de los conceptos Una tercera estrategia fue el grupo focal para tomar en cuenta la impresion de los estudiantes acerca del proyecto ABP. El aspecto colaborativo y cooperativo fue un factor fundamental, ya que el aprendizaje ocurrio en ese contexto educativo. Para los hallazgos de esta investigacion fue tan importante el conocimiento previo como los procesos que se generaban para que la adquisicion del mismo fuera de forma significativa y funcional (Escribano & Del Valle, 2010). La estrategia de ABP constituyo en este estudio una forma para indagar las

    Los procesos de fotoionización son de una importancia fundamental [1] y encuentran aplicación en un gran número de contextos científicos: Astrofísica [2], química de las radiaciones, biología. Los investigadores de dichos campos, necesitan de valores de fiables de secciones eficaces para la fotoionización parcial, la Fotoabsorción, así como para los procesos de fotofragmentación en amplios intervalos espectrales, particularmente en estudios de modelización [3-5]. En este trabajo se ha centrado la atención sobre el oxido nítrico, que se ha considerado apropiado y relevante por varios motivos: por el trascendental papel que representa en la física y química de la alta atmosfera [6], aparte de por estar íntimamente relacionado con los problemas de contaminación. Los procesos de recombinación disociativa [7] del NO, donde los estados Rydberg se encuentran directamente implicados, son relevantes, por ejemplo, en las regiones E y F de la ionosfera [7]. En este trabajo se estudia la fotoionización del NO desde el estado fundamental con la versión molecular del método del orbital de defecto cuántico (MQDO). Para ello se calcula el diferencial de las fuerzas de oscilador parciales que constituyen los canales de fotoionización del NO desde el estado fundamental. La continuidad del diferencial de fuerza de oscilador calculada a través del umbral de fotoionización, esto es, en las regiones del espectro discreta y del continua, se adopta como criterio de calidad la escasez de datos comparativos [8].

    Carbon flux data are reported as Net Ecosystem Exchange (NEE), Gross Ecosystem Exchange (GEE), Ecosystem Respiration (ER), and Methane (CH4) flux. Measurements were made at 82 plots across various polygon geomorphic classes at research sites on the Barrow Environmental Observatory (BEO), the Biocomplexity Experiment site on the BEO, and the International Biological Program (IBP) site a little west of the BEO. This product is a compilation of data from 27 plots as presented in Lara et al. (2012), data from six plots presented in Olivas et al. (2010); and from 49 plots described in (Lara et al. 2014). Measurements were made during the peak of the growing seasons during 2006 to 2010. At each of the measurement plots (except Olivas et al., 2010) four different thicknesses of shade cloth were used to generate CO2 light response curves. Light response curves were used to normalize photosynthetically active radiation that is diurnally variable to a peak growing season average ~400 umolm-2sec-1. At the Olivas et al. (2010) plots, diurnal patterns were characterized by repeated sampling. CO2 measurements were made using a closed-chamber photosynthesis system and CH4 measurements were made using a photo-acoustic multi-gas analyzer. In addition, plot-level measurements for thaw depth (TD), water table depth (WTD), leaf area index (LAI), and normalized difference vegetation index (NDVI) are summarized by geomorphic polygon type.

    We performed low-dispersion spectroscopic observations of Comet 103P/Hartley 2 in optical wavelengths using the LOSA/F2 mounted on the 1.3 m-Araki telescope at Koyama Astronomical Observatory on UT 2010 November 4 during the close approach of the Deep Impact spacecraft to the nucleus of Comet 103P/Hartley 2 in the EPOXI mission flyby. Our observations have revealed the chemistry of the coma at optical wavelengths; including CN, C3, C2 and NH2 along with H2O from [OI] emission at 6300 Å. Resultant mixing ratios of these radicals put the comet into the normal group in chemical composition. The mixing ratios with respect to H2O obtained in our observations are basically consistent with the previous optical spectro-photometric observations of Comet 103P/Hartley 2 in 1991 by A'Hearn et al. (A'Hearn, M.F., Millis, R.L., Schleicher, D.G., Osip, D.J., Birch, P.V. [1995]. Icarus 118, 223-270), the optical spectroscopic observations in 1998 by Fink (Fink, U. [2009]. Icarus 201, 311-334) and also consistent with the observations on UT 2010 October 27 and 29 by Lara et al. (Lara, L.M., Lin, Z.-Y., Meech, K. [2011]. Astron. Astrophys. 532, A87) (but only for the ratio relative to CN).

    Resumen El objetivo de este estudio fue desarrollar fotonovelas, un tipo de novela gráfica popular en la población latina, para crear conciencia y educar sobre los trastornos de la conducta alimentaria (TCA). Cuatro caricaturas ilustradas y guiones adaptados para adultos y adolescentes de ambos sexos fueron presentados en discusiones focales y en una entrevista de profundidad. Diecisiete latinos adultos (14 mujeres; 3 hombres) y 10 adolescentes (9 féminas; 1 varón) participaron en el estudio. Los participantes encontraron las fotonovelas interesantes y que captaban más la atención que los folletos tradicionales. El uso del espanglish y la clarificación de las diferencias entre los TCA fueron sugeridos por las adolescentes femeninas. Los adultos varones sugirieron cambiar el título, que se enfocara en las consecuencias en la salud de los TCA para que llame la atención en los hombres a leer la historia. Basado en la aceptación encontrada en este estudio, la fotonovela pudiera ser una avenida prometedora para crear conciencia y educar a la comunidad latina sobre los TCA en los Estados Unidos.

    Santa María Tixmadejé (SMT), Estado de México, Mexico is a town located very close to the Acambay-Tixmadejé fault. This fault is located in the middle of the Trans Volcanic Belt in the center of the Mexican territory and generated a large seismic event in 1912 with magnitude 6.9 which combined with the local vulnerability, caused a disaster. In this work we measure the different vulnerabilities of the SMT community: structural, economical, social and educational. In addition, we determinate the total vulnerability, by summing all estimated vulnerabilities, for the critical facilities identified in this town. Vulnerability was determined using the methodology proposed by National Oceanic Atmospheric Administration (NOAA) and by Disaster Prevention National Center (CENAPRED). Besides, we considered a minimum sample statistically significant of the total houses with a random sampling for our survey. Our results indicate that 50% of the critical facilities have high and very high and the other 50% between low and moderate level of total vulnerability. The results for independent vulnerabilities are as follows: (1) Near to 75% of the community has high and very high level of social vulnerability and the range for the another 25% is between low and moderate; (2) About 43% of the community has high and very high economical vulnerability and 57% low and moderate; (3) Approximately 38% of the population has high and very high educational vulnerability. The 62% present low and moderate vulnerability; and (4) About 42% of the community has very high structural vulnerability and 58% between low and moderate.

    We demonstrate that the space formed by the star formation rate (SFR), gas-phase metallicity (Z), and stellar mass (M {sub *}) can be reduced to a plane, as first proposed by Lara-Lopez et al. We study three different approaches to find the best representation of this 3D space, using a principal component analysis (PCA), a regression fit, and binning of the data. The PCA shows that this 3D space can be adequately represented in only two dimensions, i.e., a plane. We find that the plane that minimizes the {chi}{sup 2} for all variables, and hence provides the best representation ofmore » the data, corresponds to a regression fit to the stellar mass as a function of SFR and Z, M {sub *}= f(Z, SFR). We find that the distribution resulting from the median values in bins for our data gives the highest {chi}{sup 2}. We also show that the empirical calibrations to the oxygen abundance used to derive the Fundamental Metallicity Relation have important limitations, which contribute to the apparent inconsistencies. The main problem is that these empirical calibrations do not consider the ionization degree of the gas. Furthermore, the use of the N2 index to estimate oxygen abundances cannot be applied for 12 + log(O/H) {approx}> 8.8 because of the saturation of the [N II] {lambda}6584 line in the high-metallicity regime. Finally, we provide an update of the Fundamental Plane derived by Lara-Lopez et al.« less

    Landscape ecology research relies on frameworks based on geographical information systems (GIS), geostatistics and spatial-feature relationships. With regard to health, the approach consists of systems analysis using a set of powerful tools aimed at the reduction of community vulnerability through improved public policies. The north-oriental malaria focus, one of five such foci in Venezuela, situated in the north-eastern part of the Estado Sucre state, unites several social and environmental features and functions as an epidemiological corridor, i.e. an endemic zone characterised by permanent interaction between the mosquito vector and the human host allowing a continuous persistence of the malaria lifecycle. A GIS was developed based on official cartography with thematic overlays depicting malaria distribution, socio-economic conditions, basic environmental information and specific features associated with the natural wetlands present in the area. Generally, malaria foci are continuously active but when the malaria situation was modelled in the north-oriental focus, a differential, spatio-temporal distribution pattern situation was found, i.e. a situation oscillating between very active and dormant transmission. This pattern was displayed by spatial and statistical analysis based on the model generated in this study and the results were confirmed by municipal and county malaria records. Control of malaria, keeping the incidence at a permanently low level within the regional population, should be possible if these results are taken into account when designing and implementing epidemiological surveillance policies.

    The last decade has seen an unprecedented, worldwide acceleration of environmental and climate changes. These processes impact the dynamics of natural systems, which include components associated with human communities such as vector-borne diseases. The dynamics of environmental and climate variables, altered by global change as reported by the Intergovernmental Panel on Climate Change, affect the distribution of many tropical diseases. Complex systems, e.g. the El Niño/La Niña-Southern Oscillation (ENSO), in which environmental variables operate synergistically, can provoke the reemergence and emergence of vector-borne diseases at new sites. This research investigated the influence of ENSO events on malaria incidence by determining the relationship between climate variations, expressed as warm, cold and neutral phases, and their relation to the number of malaria cases in some north-eastern municipalities of Venezuela (Estado Sucre) during the period 1990-2000. Significant differences in malaria incidence were found, particularly in the La Niña ENSO phases (cold) of moderate intensity. These findings should be taken into account for surveillance and control in the future as they shed light on important indicators that can lead to reduced vulnerability to malaria.

    This poster provides an overview of the on-going research project (Grant SEP-CONACYT no 167495) from the Institute of Geography at the National Autonomous University of Mexico (UNAM) that seeks to conduct a multi-temporal landslide inventory, produce a landslide susceptibility map, and estimate sediment production by using Geographic Information Systems (GIS). The Río El Estado watershed on the southwestern flank of Pico de Orizaba volcano, the highest mountain in Mexico, is selected as a study area. The catchment covers 5.2 km2 with elevations ranging from 2676.79 to 4248.2 m a.s.l. and hillslopes between 0° and 56°. The stream system of Río El Estado catchment erodes Tertiary and Quaternary lavas, pyroclastic flows, and fall deposits. The geologic and geomorphologic factors in combination with high seasonal precipitation, high degree of weathering, and steep slopes predispose the study area to landslides. The methodology encompasses three main stages of analysis to assess landslide hazards: Stage 1 builds a historic landslide inventory. In the study area, an inventory of more than 170 landslides is created from multi-temporal aerial-photo-interpretation and local field surveys to assess landslide distribution. All landslides were digitized into a geographic information system (GIS), and a spatial geo-database of landslides was constructed from standardized GIS datasets. Stage 2 Calculates the susceptibility for the watershed. During this stage, Multiple Logistic Regression and SINMAP) will be evaluated to select the one that provides scientific accuracy, technical accessibility, and applicability. Stage 3 Estimate the potential total material delivered to the main stream drainage channel by all landslides in the catchment. Detailed geometric measurements of individual landslides visited during the field work will be carried out to obtain the landslide area and volume. These measurements revealed an empirical relationship between area and volume that took the

    In order to identify the genetic characteristics of the strains of mycobacteria circulating in the Estado de México, one of the states with the lowest prevalence of tuberculosis in Mexico, spoligotyping and 12-loci MIRU-VNTR typing were used to genotype tuberculosis clinical isolates. The average age of the 183 patients analyzed was 50 (± 17) years, drug resistance was noted in 57 (31%) and multidrug resistance in 22 (12%) individuals. The results from the isolates recovered showed that 80% were located in four major Euro-American lineages: Haarlem (17%), LAM (15%), T (20%) and X (29%). Other lineages found in lower proportions were: EAI, S, Beijing, West African, Turkey, Vole and Bovis. Eighteen isolates were orphans. Only 57 isolates were grouped in nine clusters and the SIT119 (X1) showed the highest number of members (23). The LAM lineage showed an increased risk for development of drug resistance (RR=4, IC: 95%: 1.05-14.2, p = 0.03). Despite the important prevalence of four major lineages found and the diversity of strains circulating in the population, we found the presence of one of the largest populations of isolates clustered to the X lineage in a setting from a Latin American country. © 2014 APMIS.

    Autonomous NanoTechnology Swarm (ANTS) Architecture is based on Addressable Reconfigurable Technology (ART) adaptable for the full spectrum of activities in space. ART systems based on currently available electromechanical (EMS) technology could support human crews on the lunar surface within the next 10 to 15 years. Two or more decades from now, NEMS (Super Miniaturized ART or SMART) technology could perform fully autonomous surveys and operations beyond the reach of human crews. Power system requirements would range from 1 kg to generate tens of Watts for near term ART applications, such as a lunar or Mars Lander Amorphous Rover Antenna (LARA), to <0.1 kg to generate hundreds of mWatts for more advanced SMART applications.

    We re-examine the problem of calculating the positions and widths of the lowest-lying resonances in the Ps + H scattering system which consists of two electrons, one positron and one proton. The first of these resonances, for L=0, was found by the methods of complex rotation and stabilization, and later described as a Feshbach resonance lying close to a bound state in the closed-channel e (+) + H (-) system. Recently, results for the L=1 and 2 scattering states were published, and it was found, surprisingly, that there is a larae shift in the positions of these resonances. In this work we repeat the analysis for L=1 and find an unexpected explanation for the shift.

    A new epiphytic moss, Zygodon catarinoi C. Garcia, F. Lara, Sérgio and Sim-Sim, was recorded from Libya for the first time. The new species is characterized by ovate to elliptic gemmae, narrowly lanceolate, loosely erect leaves, the abaxial surface of the costae in the distal 1/3-1/2 of the leaf covered with forked papillae, leaf lamina bistratose, rudimentary peristome and with cucullate smooth calyptra. This study is to collected the genus Zygodon growing on trunks of some trees in Al-Jebel Al-Akhdar (Libya) throughout the winter season (January-March, 2007) and May 2008, in order to revision the genus in Libya. The taxa moss flora of Libya after this record became 108.

    Motivated by the proposal to simulate para-Bose oscillators in a trapped-ion setup [C. Huerta Alderete and B. M. Rodríguez-Lara, Phys. Rev. A 95, 013820 (2017), 10.1103/PhysRevA.95.013820], we introduce an overcomplete, nonorthogonal basis for para-Bose Hilbert spaces. The states spanning these bases can be experimentally realized in the trapped-ion simulation via time evolution. The para-Bose states show both nonclassical and semiclassical statistics on their Fock state distribution, asymmetric field quadrature variances, and do not minimize the uncertainty relation for the field quadratures. These properties are analytically controlled by the para-Bose order and the evolution time; both parameters might be feasible for fine tuning in the trapped-ion quantum simulation.

    The indigenous Mazahua and Otomi have inhabited the same localities in Estado de México since pre-Columbian times. Their languages, Mazahua and Otomi, belong to the Oto-Manguean linguistic family, and although they share cultural traditions and a regional history that suggest close genetic relationships and common ancestry, the historical records concerning their origin are confusing. To understand the biological relationships between Mazahua and Otomi, we analyzed mitochondrial DNA (mtDNA) genetic variation. We identified the mtDNA haplogroups by restriction fragment length polymorphism typing and sequenced hypervariable region 1 of the mtDNA control region in 141 Mazahua and 100 Otomi. These results showed that Otomi exhibit a higher frequency of haplogroup A than B, whereas Mazahua exhibit the opposite pattern. In the Otomi EM population the most frequent subhaplogroups are, in order of frequency, A2, B2, and C1, whereas in the Mazahua 1 population they are B2, D1, and A2. The most frequent haplotypes (Ht) of haplogroups A and B are Ht2 (A) and Ht58 (B2g1) in Mazahua 1 and Ht8 (A2), Ht22 (A2ao1), and Ht53 (B2c2b) in Otomi EM. The genetic differences between the Mazahua 1 and Otomi EM suggest a distant shared ancestry and a moderate degree of maternal admixture that has not obscured the difference of their mtDNA patterns. These unexpected results suggest the Mazahua and Otomi probably descend from the same group but separated very early and admixed with other Mesoamerican populations before their arrival in Central Mexico. The historical evidence of conflicting relations between the Mazahua and Otomi and the almost nonexistence of marriage between them could be responsible for maintaining only a moderate degree of maternal admixture.

  5. Changes in Nitrogen Tropical Deposition Driven by Biomass Burning and Industrialization

    Until few years ago, N deposition studies and the consequences for ecosystems were focused on North Hemisphere, where most of the modern N deposition occurs. Nowadays, the pattern of N deposition has changed over the globe, calling attention to other geographical areas, including tropical regions which were the important pre-industrially(Matson et al., 1999). Substantial increases of NOx and SO2 emissions have been observed in Asia and in some regions of the tropics due to the rapid industrialization, urbanization, and deforestation (Ayers et al., 2000; Lara et al., 2001). Nevertheless,little information is available for developing regions of tropical and sub-tropical areas, where land-use changes are intense and followed by rapid urbanization, associated with a large industrial expansion. Such information is relevant, since recent estimates show that in a near future more than half of N inputs related to energy consumption in the Earth will take place in tropical and subtropical regions (Galloway et al., 1994). In addition, tropical terrestrial and aquatic systems appear to function differently from temperate systems, where N limitation is more severe than in the tropics (Matson et al, 1999). Conclusions based only in studies conducted in temperate regions may not be valid for tropical and sub-tropical regions. In the tropics the annual nitrogen wet deposition range from 2 to 10 kg N/ha/yr (Williams et al., 1997; Lara et al., 2001; IGAC 2003), according to the land cover. Brazil is largely tropical. It is considered a developing country, where developed areas with large urban centers, a large number of industries, and a high-technology agricultural system coexists with developing areas with low-technology and frontier-type agricultural systems and remote regions such as Amazon Basin. These anthropogenic activities are increasing the N wet deposition from an annual rate of 3.0 kg N/ha/yr in remote areas to an annual rate of 5.6 kg N/ha/yr in disturbed regions. If

    This work provides an overview of the on-going research project (Grant SEP-CONACYT # 167495) from the Institute of Geography at the National Autonomous University of Mexico (UNAM) that seeks to conduct a multi-temporal landslide inventory, analyze the distribution of landslides, and characterize landforms that are prone to slope instability by using Geographic Information Systems (GIS). The study area is the Río El Estado watershed that covers 5.2 km2 and lies on the southwestern flank of Pico de Orizaba volcano.The watershed was studied by using aerial photographs, fieldwork, and adaptation of the Landslide Hazard Zonation Protocol of the Washington State Department of Natural Resources, USA. 107 gravitational slope failures of six types were recognized: shallow landslides, debris-avalanches, deep-seated landslides, debris flows, earthflows, and rock falls. This analysis divided the watershed into 12 mass-wasting landforms on which gravitational processes occur: inner gorges, headwalls, active scarps of deep-seated landslides, meanders, plains, rockfalls, non-rule-identified inner gorges, non-rule-identified headwalls, non-rule-identified converging hillslopes and three types of hillslopes classified by their gradient: low, moderate, and high. For each landform the landslide area rate and the landslide frequency rate were calculated as well as the overall hazard rating. The slope-stability hazard rating has a range that goes from low to very high. The overall hazard rating for this watershed was very high. The shallow slide type landslide was selected and area and volume of individual landslides were retrieved from the watershed landslide inventory geo-database, to establish an empirical relationship between area and volume that takes the form of a power law. The relationship was used to estimate the total volume of landslides in the study area. The findings are important to understand the long-term evolution of the southwestern flank stream system of Pico de

Os resultados do estudo indicam que nas ftalocianias com caracter nao magneticas H2Pc e ZnPc se da a formacao de tres radicais muonicos paramagneticos distintos. A estrutura hiperfina destes radicais, referidos como estados I, II e III, foi caracterizada atraves da medida dos parametros de acoplamento hipefino em conjunto com a parameterizacao da sua dependencia com a temperatura. Uma quarta componente paramagnetica do sinal µSR foi tambem identificada, mas sobre a qual nao foi possivel retirar conclusoes definitivas quanto a sua origem. Verificou-se que os parametros de acoplamento hiperfino isotropicos dos tres estados identificados se encontram numa regiao de valores entre os 100 e os 150MHz para os estados I e II, enquanto que para o estado III esta quantidade toma valores em torno de 10 MHz. A estrutura electronica de todos os estados possui simetria axial, caracterizada por parametros dipolares de cerca de 15MHz para os estados I e II, e 20MHz para o estado III. A origem dos estados I e II foi determinada como sendo devida a adicao de muonio a uma das ligacoes duplas existentes nos aneis benzenicos da periferia das moleculas de ftalocianina recorrendo a calculos de estrutura electronica, tendo-se verificado a existencia de um acoplamento entre a interaccao hiperfina desses estados e modos vibracionais desses aneis. A problematica da localizacao do estado III tambem foi abordada, tomando-se como hipotese mais provavel uma posicao intersticial entre duas moleculas de ftalocianina. O estudo das interaccoes dinamicas de spin destes tres estados revelou que o estado III esta

    Automatic traffic light detection and mapping is an open research problem. The traffic lights vary in color, shape, geolocation, activation pattern, and installation which complicate their automated detection. In addition, the image of the traffic lights may be noisy, overexposed, underexposed, or occluded. In order to address this problem, we propose a Bayesian inference framework to detect and map traffic lights. In addition to the spatio-temporal consistency constraint, traffic light characteristics such as color, shape and height is shown to further improve the accuracy of the proposed approach. The proposed approach has been evaluated on two benchmark datasets and has been shown to outperform earlier studies. The results show that the precision and recall rates for the KITTI benchmark are 95.78 % and 92.95 % respectively and the precision and recall rates for the LARA benchmark are 98.66 % and 94.65 % .

    Since Rosetta spacecraft’s arrival to the comet 67P, the OSIRIS scientific imager (Optical, Spectroscopic, and Infrared Remote Imaging System, Keller et al. 2007) is successfully observing the nucleus with high spatial resolution in the 250-1000 nm range thanks to set of 26 dedicated filters.While 67P has a typical red spectral slope, the active areas tend to display bluer spectra (Sierks et al. 2015, Fornasier et al. 2015). We performed a spectral analysis of the active areas and derived spectral characteristics of them, possibly indicating the presence of material enriched in volatiles.The ‘activity thresholds’ spectral method (Oklay et al, 2015) is used for the identification of the active areas. In most cases, areas detected with this technique have been later on confirmed as active sources (Lara et al. 2015, Lin et al. 2015, Vincent et al. 2015) by direct detection of dust jets. This technique is therefore able to identify currently active areas, but also predicts which regions of the surface are likely to become activated once they receive enough insolation.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 Astrofi­sica de Andalucia, CSIC, Granada, Spain, the Scientific Support Office of the European Space Agency, Noordwijk, The Netherlands, the Instituto Nacional de Tecnica Aeroespacial, Madrid, Spain, the Universidad Politechnica 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.

    We investigated a galactosyltransferase (GalT) involved in the synthesis of the carbohydrate portion of arabinogalactan-proteins (AGPs), which consist of a beta-(1-->3)-galactan backbone from which consecutive (1-->6)-linked beta-Gal p residues branch off. A membrane preparation from 6-day-old primary roots of radish ( Raphanus sativus L.) transferred [(14)C]Gal from UDP-[(14)C]Gal onto a beta-(1-->3)-galactan exogenous acceptor. The reaction occurred maximally at pH 5.9-6.3 and 30 degrees C in the presence of 15 mM Mn(2+) and 0.75% Triton X-100. The apparent K(m) and V(max) values for UDP-Gal were 0.41 mM and 1,000 pmol min(-1) (mg protein)(-1), respectively. The reaction with beta-(1-->3)-galactan showed a bi-phasic kinetic character with K(m) values of 0.43 and 2.8 mg ml(-1). beta-(1-->3)-Galactooligomers were good acceptors and enzyme activity increased with increasing polymerization of Gal residues. In contrast, the enzyme was less efficient on beta-(1-->6)-oligomers. The transfer reaction for an AGP from radish mature roots was negligible but could be increased by prior enzymatic or chemical removal of alpha- l-arabinofuranose (alpha- l-Ara f) residues or both alpha- l-Ara f residues and (1-->6)-linked beta-Gal side chains. Digestion of radiolabeled products formed from beta-(1-->3)-galactan and the modified AGP with exo-beta-(1-->3)-galactanase released mainly radioactive beta-(1-->6)-galactobiose, indicating that the transfer of [(14)C]Gal occurred preferentially onto consecutive (1-->3)-linked beta-Gal chains through beta-(1-->6)-linkages, resulting in the formation of single branching points. The enzyme produced mainly a branched tetrasaccharide, Galbeta(1-->3)[Galbeta(1-->6)] Galbeta(1-->3)Gal, from beta-(1-->3)-galactotriose by incubation with UDP-Gal, confirming the preferential formation of the branching linkage. Localization of the GalT in the Golgi apparatus was revealed on a sucrose density gradient. The membrane preparation also incorporated [(14

    High-silica rhyolite magma fuels Earth's largest and most explosive eruptions. Recurrence intervals for such highly explosive eruptions are in the 100- to 100,000-year time range, and there have been few direct observations of such eruptions and their immediate impacts. Consequently, there was keen interest within the volcanology community when the first large eruption of high-silica rhyolite since that of Alaska's Novarupta volcano in 1912 began on 1 May 2008 at Chaitén volcano, southern Chile, a 3-kilometer-diameter caldera volcano with a prehistoric record of rhyolite eruptions [Naranjo and Stern, 2004semi; Servicio Nacional de Geología y Minería (SERNAGEOMIN), 2008semi; Carn et al., 2009; Castro and Dingwell, 2009; Lara, 2009; Muñoz et al., 2009]. Vigorous explosions occurred through 8 May 2008, after which explosive activity waned and a new lava dome was extruded.

    Nesse trabalho é apresentado um estudo do conteúdo de massa do aglomerado de galáxias A586 (z = 0.171) bem como sua distribuição espacial. Isso foi feito a partir de dados de espectroscopia multi-objeto e imageamento obtidos com o instrumento GMOS acoplado ao telescópio Gemini-Norte. A massa desse aglomerado foi estudada a partir da posição dos seus arcos gravitacionais (lentes fortes), da medida estatística da distorção na forma das galáxias de fundo (lentes fracas) e através da dispersão de velocidades de uma amostra de cerca de 30 galáxias pertencentes ao aglomerado (teorema do virial). Os dois primeiros métodos não dependem do estado dinâmico do aglomerado, enquanto que o terceiro sim. Desse modo, comparando seus resultados pode-se estimar o grau de relaxamento desse sistema. Dados de raios X presentes na literatura também serão incluídos nessa análise. Nossos resultados preliminares a partir das técnicas de lentes fracas, mostram que, supondo que a distribuição de massa desse aglomerado seja a de uma esfera isotérmica, espera-se que ele apresente uma dispersão de velocidades de 1330+/-78 km s-1, em contradicao com medidas similares feitas por Dahle et al. 2002 que encontram valores tão altos quanto 1680 km s-1. Já o estudo dinâmico resultou numa dispersão de velocidades de ~950 km s-1.

    Temephos is an insecticide widely used in Venezuela to control the proliferation of the larvae of Aedes aegypti (L.), the principal vector of dengue virus. The aim of this study was to identify the susceptibility to temephos of Ae. aegypti in four locations in western Venezuela: Lara, Tres Esquinas, Ureña and Pampanito. Larval bioassays were conducted on samples collected in 2008 and 2010, and the levels of α- and β-esterases, mixed-function oxidases, glutathione-S-transferase and insensitive acethyl cholinesterase were determined. Larval populations from western Venezuela obtained during 2008 and 2010 were found to be susceptible to temephos, with low resistance ratios and without overexpression of enzymes. The low RR values reveal the effectiveness of temephos in controlling the larval populations of Ae. aegypti. Control strategies must be vigorously monitored to maintain the susceptibility to temephos of these populations of Ae. aegypti. © 2013 Society of Chemical Industry.

    This study investigated risk factors associated with positive serological status for Trypanosoma cruzi antibodies in 26 rural communities including 905 households, 2,156 humans, and 333 dogs in Lara State, Venezuela. Serology was performed with ELISA and MABA. Data were obtained from entomological, demographic, and clinical surveys. Risk factors were determined through binary logistic regression. Seroprevalence was 7.24% in humans and 6.9% in canines. Positive serological status was positively associated with the Rhodnius prolixus vector, age, maternal history of Chagas disease, tobacco chewing, presence of mammals and birds in the household, household disarray, mud-and-wattle outbuildings, and animal nests and burrows in the peridomicile, and negatively associated with tobacco and alcohol consumption, history of cancer, and storage deposits in the peridomile. In conclusion, Chagas disease in this rural area is an old phenomenon transmitted by R. prolixus or by the transplacental route, associated with socio-cultural habits related to poverty, sylvatic surroundings, and the host's medical history.

    A rare walnut variant with a red seed coat (pellicle) was examined for alterations in its phenolic profile during development. The red-walnut (RW) pellicle was compared with two commonly colored walnut varieties: 'Lara' (brown) and 'Fernor' (light brown). Furthermore, the activities of selected enzymes of the phenylpropanoid- and flavonoid-related pathways and the relative expressions of the structural genes phenylalanine ammonia lyase ( PAL) and anthocyanidin synthase ( ANS) were examined in the pellicles of the three varieties. In the pellicles of the RWs, phenylalanine ammonia lyase (PAL) activity and related PAL expression was most pronounced in August, about one month before commercial maturity, suggesting a high synthesis rate of phenolic compounds at this development stage. The most pronounced differences between the red and light- and dark-brown varieties were the increased PAL activity, PAL expression, and ANS expression in RWs in August. The vibrant color of the RW pellicle is based on the presence of four derivatives of cyanidin- and delphinidin-hexosides.

    2007-07-27

    The discovery of functional non-coding RNA sequences has led to an increasing interest in algorithms related to RNA analysis. Traditional sequence alignment algorithms, however, fail at computing reliable alignments of low-homology RNA sequences. The spatial conformation of RNA sequences largely determines their function, and therefore RNA alignment algorithms have to take structural information into account. We present a graph-based representation for sequence-structure alignments, which we model as an integer linear program (ILP). We sketch how we compute an optimal or near-optimal solution to the ILP using methods from combinatorial optimization, and present results on a recently published benchmark set for RNA alignments. The implementation of our algorithm yields better alignments in terms of two published scores than the other programs that we tested: This is especially the case with an increasing number of input sequences.

    On 2 May 2008, a large eruption began unexpectedly at the inconspicuous Chaitén volcano in Chile's southern volcanic zone. Ash columns abruptly jetted from the volcano into the stratosphere, followed by lava dome effusion and continuous low-altitude ash plumes [Lara, 2009]. Apocalyptic photographs of eruption plumes suffused with lightning were circulated globally. Effects of the eruption were extensive. Floods and lahars inundated the town of Chaitén, and its 4625 residents were evacuated. Widespread ashfall and drifting ash clouds closed regional airports and cancelled hundreds of domestic flights in Argentina and Chile and numerous international flights [Guffanti et al., 2008]. Ash heavily affected the aquaculture industry in the nearby Gulf of Corcovado, curtailed ecotourism, and closed regional nature preserves. To better prepare for future eruptions, the Chilean government has boosted support for monitoring and hazard mitigation at Chaitén and at 42 other highly hazardous, active volcanoes in Chile.

    Purpose: Advanced, time-resolved, Compton-suppressed gamma-ray spectroscopy with germanium detectors is implemented for assaying medical isotopes to study the radioactive decay process leading to a more accurate appraisal of the received dose and treatment planning. Lowell’s Array for Radiological Assay (LARA), a detector array that is comprised of six Compton-suppressed high-purity germanium detectors, is currently under development at UMass-Lowell which combines Compton-suppression and time-and-angle correlations to allow for highly efficient and highly sensitive measurements. Methods: Two isotopes produced Brookhaven Linac Isotope Producer (BLIP) were investigated. {sup 82}Sr which is the parent isotope for producing {sup 82}Rb is often used in cardiacmore » PET. {sup 82}Sr gamma-ray spectrum is dominated by the 511keV photons from positron annihilation which prevent precise measurement of co-produced contaminant isotopes. A second project was to investigate the production of platinum isotopes. Natural platinum was bombarded with protons from 53MeV to 200MeV. The resulting spectrum was complicated due to the large number of stable platinum isotopes in the target, the variety of open reaction channels (p,xn), (p,pxn), (p,axn). Results: By using face-to-face NaI(Tl) counters 90-degrees to the Compton-suppressed germaniums to detect the 511keV photons, a much cleaner and more sensitive measurement of {sup 85}Sr and other contaminants was obtained. For the platinum target, we identified the production of {sup 188–189–191–195}Pt, {sup 191–192–193–194–195–196}Au and {sup 186–188–189–190–192–194–189–190–192–194}Ir. For example, at the lower energies (53 and 65MeV), we measured {sup 191}Pt production cross-sections of 144mb and 157mb. Considerable care was needed in following the process of dissolving and diluting the samples to get consistent results. The new LARA array will help us better ascertain the absolute efficiency of the

    Se discute la validez de diversas metodologías y su aplicación al estudio de procesos de intercambio de carga electrónico entre iones y blancos atómicos y moleculares. Para energías de impacto entre 0.05 y 5 eV / amu se emplea el método cuántico de la Coordenada de Reacción Común (CRC). A mayores energías, se utiliza el método semiclásico iconal con un desarrollo de la función de onda dinámica en estados moleculares adiabáticos, modificados con un factor de traslación común (FTC). Estos estados pueden obtenerse con cálculos ab initio o empleando potenciales modelo. Cuando la ionización compite con la transferencia de carga, la inclusión de pseudoestados en estos desarrollos permite calcular simultáneamente las secciones eficaces de ambos procesos. Otra técnica utilizada es el método estadístico CTMC. En el tratamiento de colisiones ión-molécula (diatómica) contrastamos la aplicabilidad de distintos métodos, desde la llamada aproximación Franck-Condon hasta un desarrollo en estados vibrónicos, pasando por la aproximación súbita vibro-rotacional, obteniéndose secciones eficaces de captura electrónica total y a estados individuales, así como secciones de excitación vibracional a estados ligados y del continuo (disociación). En todos los casos es necesario calcular superficies de energía y los correspondientes acoplamientos dinámicos entre los estados. La aplicación de estos métodos permite determinar el grado de contaminación de los haces por estados metaestables en un experimento dado, el cambio en los resultados con diferentes isótopos, la importancia de procesos de doble captura, seguida de explosión culombiana, todo ello con precisión comparable a la de medidas experimentales, para sistemas de interés en distintos tipos de plasmas.

    A polysaccharide with a molecular weight of 13,029Da was isolated from Momordica charantia (MCP) fruit and purified by ion-exchange and size-exclusion chromatography. The isolated polysaccharide MCPIIa contained L-Rha, D-GalA, D-Gal, D-Xyl, L-Ara in a molar ratio of 12:3.05:19.89:5.95:56. IR spectrum and NMR studies indicated that the MCPIIa sugar units were linked, via β-glycosidic bonds, to a large number of arabinofuranose, glucuronic acid, and xylopyranosyl residues. In addition, the hypoglycemic effect of MCPIIa was investigated in streptozotocin (STZ)-induced diabetic mice. After STZ-induction, MCPIIa (100, 200, or 300mg/kg body weight) was administered orally, once daily, for 28days. Glycemia in STZ-diabetogenic mice was significantly reduced, and compared with diabetes mellitus (DM) mice, serum insulin concentration increased significantly, following MCPIIa administration. Transmission electron microscopy showed an alleviation of STZ-lesions in pancreatic tissue from mice treated with MCPIIa. These results indicate that MCPIIa may be useful as an anti-diabetic agent.

    The presence of a liquid core inside Mars changes the nutations: the nutation amplitudes can be resonantly amplified because of a free mode, called the free core nutation (FCN).We quantify how the internal structure, in particular the size of the core, affects the nutation amplifications and the Doppler observable between a Martian lander and the Earth.Present day core size estimates suggest that the effect is the largest on the prograde semi-annual and retrograde ter-annual nutation.We solve the inverse problem assuming a given precision on the nutation amplifications provided by an extensive set of geodesy measurements and we estimate the precision on the core properties. Such measurements will be available in the near future thanks to the geodesy experiments RISE (InSight mission) and LaRa (ExoMars mission).We find that the precision on the core properties is very dependent on the proximity of the FCN period to the ter-annual forcing (-229 days) and the assumed a priori precision on the nutations.

    Farmers could perform their farming if they have sovereignty on their farming production inputs and marketing. Suboptimal land, such as dry land and swamps areas have good prospect if applying appropriate technologies. A research in 2015, on status of farmers’ sovereignty, had been conducted in Piani and North Candi Laras Subdistricts, Tapin District, South Borneo Province, representing swamp land and dry land respectively. Data and information were obtained through interviewing related agencies at provincial and district levels and 30 units of farmer’s households. The primary and secondary data were analyzed descriptively. The research results showed that farmers in swamps and dry land were categorized as large farmers and had sovereignty over the land and production. Water shortage and excessive in both land types could be overcome by giving access on appropriate technology such as programs making farmers improve their farming techniques and providing levees. In addition, land certification program, farming expansion and constructing new irrigated lowland were also some efforts to improve farmers’ sovereignty. It was crucial to identify and improve farmer’s sovereignty indicators through research in larger sites and samples.

    On February 5, 2010, occurred a fracture on a wall of the artificial water channel called “La Compañía (CC)” in the section of the municipality of Valle de Chalco Solidaridad (VCS), Estado de Mexico, Mexico. The dimensions of this fracture were 70m length, 20m wide and 5m height, and cause severe wastewater flooding that affected surrounding communities. This area was also impacted by a similar event in 2000 and 2005. In this study, we assess the social, economic, structural, and physical vulnerability to floods, earthquakes, subsidence, and landslides hazards in the communities of El Triunfo, San Isidro and Avandaro of VCS. This area is located in soil of the old Chalco Lake, and in recent decades has experienced a large population growth. Due to urban development and the overexploitation of aquifers, the zone is also exposed to subsidence up to 40 cm per year. For these reasons, CC is at present, well above ground level. In this research, we applied the methodology developed by the National Oceanic and Atmospheric Administration (NOAA) to assess vulnerability. As a first step, we established the level of exposure of the communities to the four main hazards. We also analyzed the economic and social vulnerability of the area using data collected from a field survey. From the total family houses in the studied communities, we estimated a minimum sample statistically significant and the households from this sample were selected randomly. We defined five levels of vulnerability: very low, low, moderate, high, and very high. Our results indicate that San Isidro is the community with the highest level of structural vulnerability, as for the physical vulnerability it was found that the homes most affected by flooding are those located close to CC but we did not found a direct relationship between the physical vulnerability and structural vulnerability. The main hazard to which the zone of study is exposed is flooding because its period of recurrence is about five

    El proceso de formación de futuros deportistas debe ser un trabajo estructurado y planificado para poder alcanzar el máximo nivel deportivo. Es fundamental en este periodo tener presentes los ritmos de desarrollo y maduración de los jóvenes deportistas para así adecuar las cargas de entrenamientos a sus estados evolutivos. El objetivo del estudio fue determinar y analizar la edad morfológica en nadadores y triatletas adolescentes, estableciendo diferencias entre su edad cronológica, grupos y género. A través del método antropométrico se determinó el estado de maduración biológica en un grupo de 37 deportistas jóvenes tecnificados. Los resultados muestran que la mayoría de la muestra (70,8%) se encuentra en un estado avanzado de desarrollo con respecto a su edad cronológica, siendo más notorio en el caso de los nadadores este estado de madurez avanzado. Tener una edad morfológica más avanzada respecto a su edad cronológica podría favorecer a los deportistas adolescentes a la hora de conseguir mejores marcas y resultados en las competiciones y de esta manera acceder con más facilidad a los programas de tecnificación. El índice de desarrollo corporal modificado (IDCm) se presenta como un método validado, fiable y no invasivo para tener presente el grado de desarrollo y maduración en la selección de talentos deportivos y adecuar las cargas de entrenamiento al estado evolutivo de los deportistas.

    Disk averaged observations of several H2O far infrared lines in Titan’s atmosphere were performed with the Herschel Space Observatory, as part of the guaranteed time key program "Water and related chemistry in the Solar System" (HssO, see Hartogh et al 2011). Two instruments were used: (i) HIFI, a heterodyne instrument (R~ 106 ) in the sub-millimeter, which measured the H2O(110-101) rotational transition at 557 GHz on June 10 and Dec. 31, 2010 (ii) PACS, a photoconductor spectrometer (R~103) which measured three water lines at 108.1, 75.4 and 66.4 microns on June 22, 2010. Additional PACS measurements at 66.4 microns on Dec. 15 and 22, 2010 and on July 09, 2011, do not show any significant line intensity variation with time, nor between the leading/trailing sides (i.e. longitude). Spectra were analyzed with a line-by-line radiative transfer code accounting for spherical geometry (Moreno et al. 2011). This model considers the H2O molecular opacity from JPL catalog (Pickett et al. 1998) and also includes collision-induced opacities N2-N2, N2-CH4 and CH4-CH4 (Borysow and Frommhold 1986, 1987, Borysow and Tang 1993). Far infrared aerosol opacities derived by CIRS were included, following Anderson and Samuelson (2011) for their vertical distribution and spectral dependencies. Analysis of the 557 GHz narrow line (FWHM ~ 2 MHz) indicates that it originates at altitudes above 300 km, while lines measured with PACS probe mainly deeper levels (80-150 km). The HIFI and PACS observations are fitted simultaneously, considering a vertical distribution of H2O mixing ratio which follows a power law dependency q=q0(P/P0)n, where q0 is the mixing ratio at some reference pressure level P0, taken near the expected condensation level. Model fits will be presented, and compared with previously proposed H2O vertical distributions. We show in particular that both the steep profile proposed by Lara et al. (1996) (and adopted by Coustenis et al. (1998) to model the first detection of H2O

    The dissemination of health-related news through newspapers can influence the behavior of patients and of health care providers. We conducted a study to analyze the characteristics of health-related research published by two leading Brazilian newspapers. We retrospectively evaluated health-related news published in the electronic versions of the newspapers Folha de São Paulo and O Estado de São Paulo over a period of three months (July through September, 2009). Only articles mentioning medical research were included. The articles were categorized according to topic, source, study location and the nature of the headline. We also analyzed the presence of background information on the topic, citations of medical periodicals, national contextualization and references to products or companies. Scientific research articles corresponded to 57% and 20% of health-related articles published by Folha de São Paulo and O Estado de São Paulo, respectively. Folha de São Paulo published significantly more articles about national studies, and most articles were written by its own staff. In contrast, most articles in O Estado de São Paulo came from news agencies. Folha de São Paulo also better contextualized its reports for Brazilian society. O Estado de São Paulo tended to cite the name of the periodical in which the study was published more frequently, but their articles lacked national contextualization. The results showed a significant difference in the way in which the studied newspapers report on health-related research. Folha de São Paulo tends to write its own articles and more frequently publishes the results of national research, whereas O Estado de São Paulo publishes articles that originate in news agencies, most of which have little national contextualization.

    We provide a detailed report on the reproductive biology of the Red-ruffed Fruitcrow (Pyroderus scutatus granadensis). Eight nests were found between 2003 and 2007 in tropical montane cloud forest in Yacambu National Park, Lara, Venezuela. All nests were near streams in steep drainages. Nests consisted of twigs arranged in a cupped platform. Clutch size was a single egg and the average incubation period (n = 3) was 22.3 days. Nest attentiveness during incubation averaged [?? SE] 76.3 ?? 1.86% and increased only slightly across stages (early, middle, late). On-bout and off-bout durations were relatively similar across incubation stages. A nestling period of 35 days was recorded for one nest and feather pin-break was estimated to occur at day 19. Brooding attentiveness during the early nestling period averaged 62.5 ??6.41%, and the adult ceased brooding at about feather pin-break. Food delivery rates increased with nestling age. Food provisioning consisted mostly of insects (66.7%) and lizards (25%) with fruit comprising only 8.3% of the nestling diet at early stages. Provisioning changed to mostly fruit (82.4%) and some insects (17.6%) in late stages of the nestling period.

Rev. Lett. 103, 263201 (2009)] by including periodic boundary conditions while the dispersion is parametrized via the method of increments [H. Stoll, J. Chem. Phys. 97, 8449 (1992)]. Starting with the elementary cluster unit of the target surface (benzene), continuing through the realistic cluster model (coronene), andmore » ending with the periodic model of the extended system, modern ab initio methodologies for intermolecular interactions as well as state-of-the-art van der Waals-corrected density functional-based approaches are put together both to assess the accuracy of the composite scheme and to better characterize the Ag{sub 2}/graphene interaction. The present work illustrates how the combination of DFT and post-HF perspectives may be efficient to design simple and reliable ab initio-based schemes in extended systems for surface science applications.« less

    Emerging multidrug-resistant (MDR) nosocomial pathogens are a great threat. Polymyxins, an old class of cationic polypeptide antibiotic, are considered as last-resort drugs in treating infections caused by MDR Gram-negative bacteria. Increased use of polymyxins in treating critically ill patients necessitates routine polymyxin susceptibility testing. However, susceptibility testing both of colistin and polymyxin B (PMB) is challenging. In this review, currently available susceptibility testing methods are briefly discussed. The multicomponent composition of colistin and PMB significantly influences susceptibility testing. In addition, poor diffusion in the agar medium, adsorption to microtitre plates and the synergistic effect of the surfactant polysorbate 80 with polymyxins have a great impact on the performance of susceptibility testing methods This review also describes recently identified chromosomal resistance mechanisms, including modification of lipopolysaccharide (LPS) with 4-amino-4-deoxy-l-arabinose (L-Ara4-N) and phosphoethanolamine (pEtN) resulting in alteration of the negative charge, as well as the plasmid-mediated colistin resistance determinants mcr-1, mcr-1.2, mcr-2 and mcr-3.

    Objetivo: el propósito del estudio fue relacionar la etapa en el cambio en el comportamiento frente a la actividad física y el estado nutricional en escolares de Bogotá, Colombia, pertenecientes al estudio FUPRECOL.Método: se trata de un estudio transversal, realizado en 8.000 niños y adolescentes de entre 9 y 17 años, pertenecientes a 24 instituciones educativas. Se aplicó de manera autodiligenciada el cuestionario de cambio de comportamiento en función de la intención de realizar actividad física (CCC-FUPRECOL) y se midió el peso y la estatura para determinar el estado nutricional con el índice de masa corporal (IMC).Resultados: el porcentaje de respuesta fue del 82,5% y se consideraron válidos 6.606 registros, siendo el 58,3% (n = 3.850) niñas, con un promedio de edad de 12,7 ± 2,3 años. En la población general, el 5,3% de los escolares se encontraba en etapa de precontemplación, el 31,8% en contemplación, el 26,7% en acción y el 36,2% en etapa de mantenimiento. Al comparar la etapa de cambio con el estado nutricional por IMC, los escolares clasificados como obesos mostraron mayor frecuencia de respuesta en la etapa de precontemplación, mientras que los escolares con peso saludable acusaron mayores porcentajes en la etapa de mantenimiento.Conclusión: en escolares de Bogotá, Colombia, se encontró una relación estadísticamente significativa entre la intención de realizar actividad con el estado nutricional medido con el IMC. Fomentar la promoción de la actividad física y monitorizar el estado nutricional deberá ser una prioridad en las agendas y políticas públicas dentro del ámbito escolar.

    Introducción: la categorización del estado nutricional a través del índice de masa corporal (IMC) es uno de los recursos de valoración clínica más utilizados en el síndrome metabólico (SM). Sin embargo, es desconocida su capacidad para identificar las diferencias en la composición corporal.Objetivo: determinar si las variaciones en el estado nutricional se reflejan en la composición corporal en mujeres con SM e identificar la concordancia de clasificación del riesgo cardiometabólico entre el estado nutricional e índices antropométricos.Material y métodos: la muestra incluyó 136 mujeres (edad 42 ± 3,5 años) con SM. Se evaluó el estado nutricional, masa muscular, masa adiposa, perímetro de cintura (PC), índice cintura-cadera (ICC) e índice cintura-estatura (ICE). Se compararon los valores de composición corporale índices antropométricos; adicionalmente se determinó la concordancia clasificatoria del riesgo cardiometabólico entre los índices y el IMC.Resultados: solo la edad (p = 0,358), estatura (p = 0,209) y porcentaje de adiposidad (p = 0,234) no mostraron diferencias significativas entre los grupos. La mejor concordancia clasificatoria del riesgo cardiometabólico se observó en el PC > 88 cm (94,9%) e ICE ≥ 0,5 (94,1%) al categorizar el IMC en normopeso vs. exceso de peso; mientras que el PC > 88 cm obtuvo mejor concordancia separando al grupo en normopeso-sobrepesovs. obesidad (85,3%), aunque la sensibilidad y especificidad fueron más homogéneas con el ICC ≥ 0,85.Conclusión: el IMC no logra identificar las variaciones de la adiposidad corporal en mujeres con SM agrupadas según su estado nutricional. El IMC presenta mejor sensibilidad que especificidad respecto a los índices considerados para determinar riesgo cardiometabólico en mujeres con SM.

    RESUMEN EJECUTIVO El impulso para desarrollar e implementar estrategias de medicina integrativa está enraizado en el deseo de mejorar la atención al paciente. The Bravewell Collaborative, una organización sin ánimo de lucro dedicada a la mejora de la atención sanitaria, define la medicina integrativa como “un enfoque de la medicina que coloca al paciente en el centro y se dirige al conjunto completo de influencias físicas, emocionales, mentales, sociales, espirituales y ambientales que afectan a la salud de la persona. Con una estrategia personalizada que considera las condiciones, necesidades y circunstancias únicas del paciente, utiliza las intervenciones más apropiadas de una variedad de disciplinas científicas para curar la afección y la enfermedad y ayudar a las personas a recobrar y mantener una salud óptima”. En las pasadas dos décadas, se ha documentado un número creciente de centros clínicos que proporcionan medicina integrativa, el número de facultades y escuelas médicas que enseñan estrategias integrativas, el número de investigadores que estudian intervenciones integrativas, y el número de pacientes que solicitan cuidados integrativos. Pero se desconocía si la medicina integrativa se estaba ofreciendo de manera igual, similar, o dispar. Además, mientras que los estudios anteriores se centraban en la prevalencia y el uso de la medicina complementaria o alternativa (MCA) por parte de los pacientes1,2 o de los médicos en hospitales3, enumerando la utilización de terapias MCA individuales, se había recogido muy poca información con respecto a la práctica real de la medicina integrativa que, por definición, trata a la persona en su conjunto. En 2011, The Bravewell Collaborative encargó una encuesta para determinar la forma en que la medicina integrativa se estaba practicando en los Estados Unidos: (1) describiendo las poblaciones de pacientes y las afecciones sanitarias tratadas más habitualmente; (2) definiendo las pr

    El índice de masa corporal (IMC) otorga uno de los índices más usados para determinar el estado nutricional de la población a nivel mundial, donde a pesar de existir recomendaciones claras y definidas para su interpretación como el sexo, edad, raza, entre otros, normalmente se estandariza su clasificación, independiente de las variables, aumentando el error en el resultado y en la clasificación del estado nutricional.El uso de la composición corporal a través de la antropometría entrega mayor información que el IMC, siendo la masa grasa y la masa muscular los principales resultados útiles.Este artículo presenta una revisión de las ecuaciones existentes y propone aquellas más simples y con menor error de estimación para ser usadas como una herramienta que reemplace o complemente al IMC, favoreciendo una mejor comprensión e interpretación del estado nutricional y nivelde actividad física en niños y adolescentes.

    We present our experience on the design and development of a gynaecology and obstetrics graduate residency programme, developed in the Department of Obstetrics and Gynecology at the Dr Adolfo Prince Lara Hospital, Puerto Cabello, Venezuela, in which medical specialists and residents participate synergistically. From January to September 1993, curricular activities were planned and students selected. The programme started in October 1993, with six residents for a three-year programme. Courses were given by medical specialists from the Department. In addition to a Programme Coordinator, there is also a Residents' Coordinator, appointed for a two-month term of office; specific functions were assigned for residents occupying this position. All the programmed activities for three years were accomplished, including lectures and rotations, with an important record of surgical interventions. In our grade system, residents got an average of 18 over a maximum of 20 points. Residents also participated as speakers in workshops, special courses and national medicinal meetings, in which they presented a total of nine papers. Activities were evaluated bimonthly in meetings with students and each semester by the Graduate Committee. The first class graduated in September 1996. Results suggest that resident participation in graduate programmes is an important part of their education. PMID:9538482

    Desde el descubrimiento de fuertes excesos infrarrojos en β Pictoris, esta estrella ha sido muy estudiada y es considerada candidata a poseer un sistema planetario propio. β Pic está rodeada de un disco asimétrico de polvo que se observa de canto y que esta vacío a distancias <= 40 AU. Esto se considera una fuerte evidencia en favor de la presencia de (al menos) un planeta gigante. Recientemente se han observado líneas de material circunestelar que se han interpretado como consecuencia de la caída de objetos cometarios sobre esta estrella. Recientemente se ha utilizado la existencia del disco de polvo para atribuir una edad corta (pre - secuencia principal) a βPic. Sin embargo, la evaporación de estos cometas provee suficiente polvo como para explicar la presencia del disco observado sin necesidad de edades cortas. En este trabajo mostramos que la comparación entre la tasa de impactos cometarios estimada en el Sistema Solar para diferentes etapas de su evolución y los datos observados en β Pic indica edades avanzadas para β Pic. Esta estimación debe tomarse con cautela ya que depende de la estructura de los sistemas planetarios. Además mostramos que, desde el punto de vista de la evolución estelar y con las incertezas presentes en la luminosidad y la temperatura efectiva, existe un continuo de edades posible para β Pic. Sin embargo, empleando los datos provenientes de los flujos cometarios encontramos que una edad prolongada es consistente con ambos tratamientos.

    Fundamento y objetivo Determinar la asociación entre fragilidad y mortalidad, dependencia funcional, caídas y hospitalizaciones en el Estudio Nacional de Salud y Envejecimiento en México (ENASEM). Sujetos y métodos Estudio prospectivo poblacional en México en el que se seleccionaron sujetos de 60 años o más, que fueron evaluados en las variables de fragilidad durante la primera vuelta del estudio en el año 2001 y que incluyó: dificultad para levantarse de una silla después de haber estado sentado(a) durante largo tiempo, pérdida de peso de 5 kilogramos o más en los últimos dos años y falta de energía. Los sujetos fueron catalogados como robustos, prefrágiles y frágiles cuando tenían cero, una o dos de las características anteriores, respectivamente. La mortalidad, hospitalizaciones, caídas y dependencia funcional fueron evaluadas en la segunda vuelta del estudio en el año 2003. Se calculó el riesgo relativo para cada una de las complicaciones, así como análisis multivariado con regresión de Cox para el caso de mortalidad y regresión logística para el resto. Resultados Los estados de prefragilidad y fragilidad se asociaron independientemente con mortalidad, con índices de riesgo ajustados de 1,61 (intervalo de confianza del 95% [IC 95%] 1,01-2,55) y 1,94 (IC 95% 1,20-3,13), respectivamente. Sólo el estado de fragilidad se asoció independientemente con hospitalización y dependencia funcional, con una razón de momios ajustada de 1,53 (IC 95% 1,13-2,07) y 3,07 (IC 95% 1,76-5,34), respectivamente. No hubo asociación entre los estados de prefragilidad y fragilidad con caídas. Conclusión El estado de fragilidad se asocia independientemente con mortalidad, hospitalizaciones y disfuncionalidad en actividades básicas de la vida diaria en los siguientes dos años en población mexicana.

    Valle de Chalco Solidaridad is located in Mexico City Metropolitan Area in Estado de Mexico, Mexico. In this town there is a sewage canal called “La Compañía”. A wall of this canal collapsed on February 5, 2010 due to heavy rains creating the flooding of four surrounding communities. It is important to point out that this area is frequently exposed to floods. In this work, we consider a critical facility as an essential structure for performance, health care and welfare within a community or/and as a place that can be used as shelter in case of emergency or disaster. Global vulnerability (the sum of the three measured vulnerabilities) of the 25 critical facilities identified in the locations of Avándaro, San Isidro and El Triunfo was assessed using the Community Vulnerability Assessment Tool developed by the National Oceanic and Atmospheric Administration (NOAA). For each critical facility we determined its operational, structural and physical vulnerabilities. For our analysis, we considered the four main natural hazards to which Valle de Chalco is exposed: earthquakes, floods, landslides and sinking. We considered five levels of vulnerability using a scale from 1 to 5, where values range from very low to very high vulnerability, respectively. A critical facilities database was generated by collecting general information for three categories: schools, government and church. Each facility was evaluated considering its location in relation to identified high-risk areas. Our results indicate that in average, the global vulnerability of all facilities is low, however, there are particular cases in which this global vulnerability is high. The average operational vulnerability of the three communities is moderate. The global structural vulnerability (sum of the structural vulnerability for the four analyzed hazards) is moderate. In particular, the structural vulnerability to earthquakes is low, to landslides is very low, to flooding is moderate and to sinking is

    Resumen Introducción La impulsividad es un rasgo de personalidad multidimensional relacionado con el control del comportamiento y las emociones. Está presente de manera diversa en los trastornos de la conducta alimentaria, particularmente, en la bulimia nerviosa (BN). Aunque la relación entre la impulsividad y BN ha sido objeto de numerosas investigaciones, en la actualidad se desconocen los sustratos neurobiológicos de esta relación. Objetivos Discutir críticamente la evidencia que sugiere que las alteraciones en los sistemas neuronales relacio-nados con las funciones ejecutivas, con la formación de preferencias y con la regulación de los estados emocionales sirven como base para el rasgo de personalidad impulsiva, así como su estado en subgrupos de pacientes con BN. Métodos Búsqueda selectiva de la literatura relevante. Resultados y conclusiones Esta discusión ilustra la complejidad de la relación entre la impulsividad y BN, donde la impulsividad actúa como un factor de vulnerabilidad que puede sensibilizar al sujeto con BN a estados emocionales negativos, durante los cuales modifica el impacto de estímulos internos y externos sobre el comportamiento y su regulación, favoreciendo así patrones de comportamiento maladaptativos e inflexibles.

    The data of accidents caused by snakebites in Venezuela, registered at the morbidity statistics of the Direction of Epidemiology and Strategic Analysis of the Ministry of Health and Social Development were analyzed. During the years of 1996-2004, 53,792 snakebites were registered in Venezuela (5,976 cases average per year), with a higher incidence during the year 2004 (7,486 incidents). Zulia reported the highest frequency of all the states (5,975 cases); meanwhile the Midwestern region, constituted by Lara, Portuguesa, Falc6n and Yaracuy states, had a higher morbidity for snake bites. The highest incidence, distributed per states was registered in Cojedes, during the year 2001, with 228.72 cases per 100,000 inhabitants. When it was determined by regions, the highest incidence occurred during the year 2004 at los Llanos with 63.81 per 100,000 inhabitants. The median of the incidence rate for Venezuela during the period was of 21.46 accidents per 100,000 inhabitants. The classification of the endemic areas for ophidism, according to the percentiles 23, 50, 75 and 90, organized the country in: (a) states and regions of very high endemicity, (b) high endemicity, (c) middle, (d) low and (e) very low endemicity. These epidemiological data indicated that the accidents caused by snakes constitute a collective health problem in Venezuela.

    This study addresses the composition and properties of different walnut varieties (Chandler, Hartley and Lara), in particular their virgin oils and residual cakes obtained by screw pressing employing different cultivars. Among nuts, walnut (Juglans regia L.) exhibits interesting nutritional value, mainly due to their high content in linoleic acid, phenolic and tocopherol compounds, which show antioxidant and other healthy properties. Valuable results related to fatty acid profile and minor components were observed. Virgin walnut oil is a rich source in linoleic acid (60-62%) and γ-tocopherol (517-554 mg/kg). Moreover, walnuts show a very high content in total phenolic compounds (10,045-12,474 mg/kg; as gallic acid), which contribute to a great antioxidant activity (105-170 mmol/kg for DPPH, and 260-393 mmol/kg for ORAC), being the hydrolysable tannins (2132-4204 mg/kg) and flavanols (796-2433 mg/kg) their main phenolic groups. Aldehydes account for the highest contribution to aromatic volatiles in virgin walnut oil (about 35% of total). As expected, polar phenolic compounds concentrate in the residual cake, after the separation of the oily phase, reaching a content of up to 19,869 mg/kg, leading to potential added value and applications as source of bioactive compounds to this by-product.

    The inducible lysine decarboxylase LdcI is an important enterobacterial acid stress response enzyme whereas LdcC is its close paralogue thought to play mainly a metabolic role. A unique macromolecular cage formed by two decamers of the Escherichia coli LdcI and five hexamers of the AAA+ ATPase RavA was shown to counteract acid stress under starvation. Previously, we proposed a pseudoatomic model of the LdcI-RavA cage based on its cryo-electron microscopy map and crystal structures of an inactive LdcI decamer and a RavA monomer. We now present cryo-electron microscopy 3D reconstructions of the E. coli LdcI and LdcC, and an improved map of the LdcI bound to the LARA domain of RavA, at pH optimal for their enzymatic activity. Comparison with each other and with available structures uncovers differences between LdcI and LdcC explaining why only the acid stress response enzyme is capable of binding RavA. We identify interdomain movements associated with the pH-dependent enzyme activation and with the RavA binding. Multiple sequence alignment coupled to a phylogenetic analysis reveals that certain enterobacteria exert evolutionary pressure on the lysine decarboxylase towards the cage-like assembly with RavA, implying that this complex may have an important function under particular stress conditions.

    The infrared spectrum of Titan around 40 mu m was recorded in the grating mode of the Short Wavelength Spectrometer (SWS) of ISO, with a resolving power of about 1900. Two emission features appear at 43.9 and 39.4 mu m, where pure rotational water lines are expected. Line strengths are about 8 times the 1sigma statistical noise level. The H_2O vertical profile for water suggested by the photochemical model of Lara et al. (1996), rescaled by a factor of about 0.4(+0.3}_{-0.2) , is compatible with the data. The associated water mole fraction is about 8(+6}_{-4) x 10(-9) at an altitude of 400 km (column density of 2.6(+1.9}_{-1.6) x 10(14) mol cm(-2) above the surface). The inferred water influx at 700 km in Titan's atmosphere is in the range (0.8-2.8) x 10(6) mol cm(-2) s(-1) . Based on observations with ISO, an ESA project with instruments funded by ESA Member States (especially the PI countries: France, Germany, the Netherlands and the United Kingdom) with the participation of NASA and ISAS.

    This work aims at presenting the scientific results stemming from six Short-Term Scientific Missions (STSMs) funded by the COST (European COoperation in Science and Technology) Action TU1208 'Civil Engineering Applications of Ground Penetrating Radar' (Action Chair: Lara Pajewski, STSM Manager: Marian Marciniak). STSMs are important means to develop linkages and scientific collaborations between participating institutions involved in a COST Action. Scientists have the possibility to go to an institution abroad, in order to undertake joint research and share techniques/equipment/infrastructures that may not be available in their own institution. STSMs are particularly intended for Early Stage Researchers (ESRs), i.e., young scientists who obtained their PhD since no more than 8 years when they started to be involved in the Action. Duration of a standard STSM can be from 5 to 90 days and the research activities carried out during this short stay shall specifically contribute to the achievement of the scientific objectives of the supporting COST Action. The first STSM was carried out by Lara Pajewski, visiting Antonis Giannopoulos at The University of Edinburgh (United Kingdom). The research activities focused on the electromagnetic modelling of Ground Penetrating Radar (GPR) responses to complex targets. A set of test scenarios was defined, to be used by research groups participating to Working Group 3 of COST Action TU1208, to test and compare different electromagnetic forward- and inverse-scattering methods; these scenarios were modelled by using the well-known finite-difference time-domain simulator GprMax. New Matlab procedures for the processing and visualization of GprMax output data were developed. During the second STSM, Iraklis Giannakis visited Lara Pajewski at Roma Tre University (Italy). The study was concerned with the numerical modelling of horn antennas for GPR. An air-coupled horn antenna was implemented in GprMax and tested in a realistically

    Los estados Rydberg moleculares han suscitado en los últimos años un creciente interés entre los espectroscopistas experimentales, motivado en parte por el desarrollo de nuevas técnicas espectroscópicas capaces de investigar estos estados altamente excitados electrónicamente. Los procesos de fotoabsorción que implican estados Rydberg en los derivados halogenados del metano son de gran importancia, debido a su abundancia en la atmósfera y a sus implicaciones medioambientales. Por ello, la obtención de datos relativos a sus fuerzas de oscilador es de gran interés. En este trabajo se aborda el estudio de dichas propiedades para las moléculas isovalentes CF3Cl y CF3Br. Ambas moléculas presentan idéntica estructura electrónica para el estado fundamental por lo que se espera que sus espectros Rydberg presenten grandes similitudes, en ausencia de perturbaciones. Por ello y dada la escasez de datos relativos a fuerzas de oscilador, hemos establecido la corrección de nuestros resultados en base a las analogías esperadas en las intensidades espectrales correspondientes a transiciones análogas. Por otro lado, Novak y col. [1] han encontrado experimentalmente un marcado carácter atómico en el espectro correspondiente a estas moléculas, siendo muy similar a los de los átomos de Cl y Br. Por ello en el presente trabajo, además de establecer la comparación entre ambas moléculas hemos buscado las similitudes con sus respectivos halógenos. Los cálculos relativos a las especies moleculares se han realizado utilizando la Metodología Molécular de Orbítales de Defecto Cuántico (MQDO) [2], mientras que para el estudio de los átomos de Cl y Br se empleó la versión relativista del método (RQDO) [3].

    Introducción. La etapa posprandial se asocia con el incremento de marcadores relacionados con el riesgo cardiovascular, cuya intensidad depende del estado metabólico.Objetivo. Determinar el impacto de la ingestión de una comida rica en grasas saturadas sobre el perfil metabólico e inflamatorio y su relación con la obesidad abdominal.Materiales y métodos. Se hizo un ensayo clínico en 42 individuos (21 con obesidad abdominal). Se midieron, en sangre, la glucosa, la insulina, el perfil lipídico, la proteína C reactiva, los lipopolisacáridos y la interleucina 6, en ayunas y después de la ingestión.Resultados. Además de la obesidad, se registró la presencia de resistencia a la insulina y de niveles elevados de triacilglicéridos y proteína C reactiva en ayunas. Asimismo, se detectaron niveles posprandiales más elevados de glucosa, insulina y triacilglicéridos. La interleucina 6 disminuyó en el grupo de personas sin obesidad y los lipopolisacáridos aumentaron en ambos grupos.Conclusión. La ingestión de una comida rica en grasas saturadas produjo un mayor impacto en las variables glucémicas en el grupo con obesidad y, aunque afectó de forma similar los lípidos en ambos grupos, el incremento de triacilglicéridos fue mayor en presencia de una concentración basal elevada y promovió el aumento de lipopolisacáridos. El estado inflamatorio basal y posprandial afectó en mayor medida al grupo con obesidad. El momento posprandial reflejó el estado más frecuente de los individuos en un día normal y permitió evidenciar la capacidad de respuesta metabólica frente a la ingestión de alimentos, así como los estados tempranos de riesgo metabólico.

    Basándonos en extensos y precisos cómputos de funciones de partición realizados por nosotros para distintos átomos, se muestra que en el cálculo u obtención de ciertas magnitudes (notablemente la presión electrónica, la abundancia de un elemento deducida a partir de un estado fuertemente ionizado, etc.) el error porcentual que se comete es pequeño (inferior a 1 %) si se adopta, como valor de la función de partición, el peso estadístico del término correspondiente al estado fundamental del átomo. Esta notable simplificación acelera el cálculo, por ejemplo, de un modelo de atmósfera estelar, sin disminuir la precisión de los resultados.

    Background The prevalence of dyslipidemia in multiple regions of Venezuela is unknown. The Venezuelan Metabolic Syndrome, Obesity and Lifestyle Study (VEMSOLS) was undertaken to evaluate cardiometabolic risk factors in Venezuela. Objective To determine the prevalence of dyslipidemia in five populations from three regions of Venezuela. Methods During the years 2006 to 2010, 1320 subjects aged 20 years or older were selected by multistage stratified random sampling from all households in five municipalities from 3 regions of Venezuela: Lara State (Western region), Merida State (Andean region), and Capital District (Capital region). Anthropometric measurements and biochemical analysis were obtained from each participant. Dyslipidemia was defined according to the NCEP/ATPIII definitions. Results Mean age was 44.8 ± 0.39 years and 68.5% were females. The prevalence of lipids abnormalities related to the metabolic syndrome (low HDL-c [58.6%; 95% CI 54.9 - 62.1] and elevated triglycerides [39.7%; 36.1 - 43.2]) were the most prevalent lipid alterations, followed by atherogenic dyslipidemia (25.9%; 22.7 - 29.1), elevated LDL-c (23.3%; 20.2 - 26.4), hypercholesterolemia (22.2%; 19.2 - 25.2), and mix dyslipidemia (8.9%; 6.8 - 11.0). Dyslipidemia was more prevalent with increasing body mass index. Conclusion Dyslipidemias are prevalent cardiometabolic risk factors in Venezuela. Among these, a higher prevalence of low HDL is a condition also consistently reported in Latin America. PMID:29538522

    1994-12-01

    The Italian National Research Council (CNR) in the framework of its `Strategic Project for Climate and Environment in Southern Italy' established a new laboratory for airborne hyperspectral imaging devoted to environmental problems. Since the end of June 1994, the LARA (Laboratorio Aereo per Ricerche Ambientali -- Airborne Laboratory for Environmental Studies) Project is fully operative to provide hyperspectral data to the national and international scientific community by means of deployments of its CASA-212 aircraft carrying the Daedalus AA5000 MIVIS (multispectral infrared and visible imaging spectrometer) system. MIVIS is a modular instrument consisting of 102 spectral channels that use independent optical sensors simultaneously sampled and recorded onto a compact computer compatible magnetic tape medium with a data capacity of 10.2 Gbytes. To support the preprocessing and production pipeline of the large hyperspectral data sets CNR housed in Pomezia, a town close to Rome, a ground based computer system with a software designed to handle MIVIS data. The software (MIDAS-Multispectral Interactive Data Analysis System), besides the data production management, gives to users a powerful and highly extensible hyperspectral analysis system. The Pomezia's ground station is designed to maintain and check the MIVIS instrument performance through the evaluation of data quality (like spectral accuracy, signal to noise performance, signal variations, etc.), and to produce, archive, and diffuse MIVIS data in the form of geometrically and radiometrically corrected data sets on low cost and easy access CC media.

    Adverse drug reactions (ADRs) represent the first cause of change of the first-line highly active antiretroviral therapy (HAART) regimen, therefore, they constitute the main limiting factor in the long-term follow up of HIV patients in treatment. A retrospective study was carried out in a specialized center in Lara State, Venezuela, including 99 patients over 18 years of age who had change of first-line HAART regimen due to ADRs, between 2010 and 2013. The aims of this research were to describe the sociodemographic and clinical variables, frequency of ADRs related to change of HAART, duration of the first-line HAART regimen, to determine the drugs associated with ARVs and to identify the risk factors. The ADRs constituted 47.5% of all causes of change of first-line HAART regimen, the median duration was 1.08±0.28 years. The most frequent ADRs were anemia (34.3%), hypersensitivity reactions (20.2%) and gastrointestinal intolerance (13.1%). The most frequent ARV regimen type was the protease inhibitors-based regimen (59.6%), but zidovudine was the ARV most linked to ADRs (41.4%). The regression analysis showed increased risk of ADRs in singles and students in the univariate analysis and heterosexuals and homosexuals in multivariate analysis; and decreased risk in active workers. The present work shows the high prevalence of ADRs in the studied population and represents the first case-based study that describes the pharmacoepidemiology of a cohort of HIV-positive patients treated in Venezuela.

    Fermentative production of optically pure lactic acid (LA) has attracted great interest because of the increased demand for plant-based plastics. For cost-effective LA production, an engineered Lactobacillus plantarum NCIMB 8826 strain, which enables the production of optically pure l-LA from raw starch, is constructed. The wild-type strain produces a racemic mixture of d- and l-LA from pyruvate by the action of the respective lactate dehydrogenases (LDHs). Therefore, the gene encoding D-LDH (ldhD) is deleted. Although no decrease in d-LA formation is observed in the ΔldhD mutant, additional disruption of the operon encoding lactate racemase (larA-E), which catalyzes the interconversion between d- and l-LA, completely abolished d-LA production. From 100 g L -1 glucose, the ΔldhD ΔlarA-E mutant produces 87.0 g L -1 of l-LA with an optical purity of 99.4%. Subsequently, a plasmid is introduced into the ΔldhD ΔlarA-E mutant for the secretion of α-amylase from Streptococcus bovis 148. The resulting strain could produce 50.3 g L -1 of l-LA from raw corn starch with a yield of 0.91 (g per g of consumed sugar) and an optical purity of 98.6%. The engineered L. plantarum strain would be useful in the production of l-LA from starchy materials. © 2018 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

    It has been widely shown that nuclear fallout includes substances, which accumulate in organisms such as crustaceans, fish, mushrooms and lichens, helping to evaluate the activity concentration of contaminants accumulated on a long time. In this context, radiocaesium deposited in soil following the Chernobyl accident on 26 April 1986 is known to have remained persistently available for plant uptake in many areas of Europe. Studies on the lichen Stereocaulon vesuvianum show the plant's high capacity to retain radionuclides from the substrate and the air. After the Chernobyl accident, starting from September 1986, at the Radioactivity Laboratory (LaRa) of the University of Naples Federico II, four monitoring campaigns to evaluate the activity concentration of four isotopes of the two elements caesium and ruthenium ( 134 Cs, 137 Cs, 103 Ru and 106 Ru) were carried out until 1999. This study allowed the effective half-life of 134 Cs and 137 Cs to be estimated. Twenty-eight years after the accident, in December 2014, a further sampling was carried out; only 137 Cs was revealed beyond the detection limits, measuring activity concentrations ranging from 20 to 40 Bq/kg, while the other radionuclides were no longer observed due to their shorter half-life. The last sampling allowed more precise determination of the effective half-life of 137 Cs (6.2 ± 0.1 year), due to the larger dataset on a large time period. Copyright © 2017 Elsevier Ltd.

    One of the most common congenital disorders that affects the facial structures is the cleft lip palate (CLP). The aim of this study was to generate the clinical-epidemiological profile of CLP patients from Hospital de Especialidades del Niño y la Mujer (HENM) Dr. Felipe Nuñez Lara, from the Ministry of Health, Queretaro, Mexico, from 2011 to 2014, who received treatment from the Cleft Lip Palate Clinic in order to provide interdisciplinary treatments for CLP patients based on the information from the pediatric records. Retrospective, cross-sectional, observational study using univariate analysis frequencies for qualitative variables; central statistical and dispersion for quantitative variables and clinical profile. One hundred records were reviewed, from which 15 were discarded for being syndromic cases. Epidemiological, clinical, and socio-demographic variables were studied. The epidemiological profile (variables associated with mother's pregnancy, patient's health at birth, nutritional and psychomotor development; family medical records, addictions, and socioeconomic factors) and clinical profile (disease classification by sex, structure, and side; surgeries classification and order in which they took place) of the treated population were registered. The results showed the need to standardize the data registration on medical records to improve the monitoring and treatment of patients and emphasize actions to maintain low incidence of CLP in Queretaro.

    The author discusses the natural gas industry in Argentina. Despite a troubled past, Argentina looks toward a future brightened by the growing prominence of natural gas use. A state-run company, Gas del Estado, controls the exploration, production, transmission and distribution of natural gas. Natural gas reserves, measured in tons of oil equivalent, grew from 51 percent of oil reserves in 1970 to 187 percent in 1983. This growth is expected to continue with gas reserves predicted to nearly triple in absolute terms to 70 Tcf, by the turn of the century. This article discusses some of the problems that Argentinamore » has in using its natural gas. The immediate obstacle is one of funds. Gas del Estado has no technical limitations but may be handicapped in its growth by economic and financial problems.« less

    Chen, Shao-Guang

    In high energy physics experiments the electric charge and rest mass of particles can commonly transform into the photons, vice versa. Its reason QFT can only give a vague answer: based on the particle creation and annihilation operators. There are not more clear answers or conjecture? At least, light, electric charge and rest mass should have a collective structure component, if not, the transformation is unable understanding. An elementary answer is that neutrino and antineutrino as their collective structure component. In the paper ‘Chen Qiliang & Wang Bin, The formation and characteristics of Chen Shaoguang's formula, China Science &Technology Overview 127101-103 (2011)’, the lowest energy state vertical polarized left spin 1/2 neutrino and right spin 1/2 antineutrino are just the left, right advance unit quanta la _{0}nuυ, ra nuυ _{0} and left, right back unit quanta lb (0) nuυ, rb nuυ (0) , it again compose into spin 1 unit photon la-ra _{0}nuυnuυ _{0} and back-photon lb-rb (0) nuυnuυ (0) , spin 0 unit rest mass ra-rb nuυ _{0}nuυ (0) and anti-mass la-lb _{0}nuυ (0) nuυ, spin 0 unit positive charge la-rb _{0}nuυnuυ (0) and negative charge ra-lb nuυ _{0} (0) nuυ. The physical vacuum is the even collocation of non-combinational nuυ _{0} or _{0}nuυ. It accord to the high energy physics experimental results of the transformation among the photons, masses quanta and charges quanta. In my paper ‘Quanta turn-advance ism, China Science && Technology Overview 131 192-210 (2011)’, QFT four-dimensional uncertainty principle and momentum-energy conservation law had been generalized as a five-dimensional equations: de Broglie wavelength as a position vector \\underline{q}= (i c t, r, s), momentum \\underline{P} = (i E / c, P, U c), \\underline{q} = i h / \\underline{P}, \\underline{q} \\underline{q} = 0, \\underline{P} \\underline{P} = 0, Sigma∑ \\underline{P} = \\underline{P} (0) .

    Desde que se formuló, en 1996, la metodología Molecular de Orbitales de Defecto Cuántico (MQDO) [1], se han obtenido datos de calidad relativos a intensidades de bandas electrónicas que implican estados Rydberg para una gran variedad de sistemas moleculares [2]. Animados por los buenos resultados obtenidos, recientemente hemos abordado el estudio de transiciones vibrónicas, es decir aquellas que ocurren entre estados vibracionales que pertenecen a distintos estados Rydberg electrónicos. Como prototipo adecuado para nuestros propósitos hemos elegido la molécula de NO, importante en la química de la atmósfera, y para la cual existen en la bibliografía datos experimentales de calidad suficiente para contrastar la validez de nuestros resultados. En concreto, hemos calculado las fuerzas de oscilador y coeficientes de Einstein para transiciones electrónicas y vibrónicas de las principales bandas del NO, al igual que vidas medias radiativas de niveles vibracionales de dicha molécula. Las propiedades estudiadas son esenciales para la comprensión de los aspectos teóricos de los procesos físicos básicos relativos a la dispersión electrónica en moléculas heteronucleares con capas abiertas. Además, valores fiables de probabilidades de transición moleculares tienen importantes aplicaciones en Astrofísica, en la modelización de procesos fotodinámicos moleculares, etc., al igual que para evaluar más profundamente la validez de nuestra metodología teórica.

    2000-01-01

    In 1944, 73 women nurses were sent to Italy to serve in World War II as part of the Forca Expedicionaria Brasileira (FEB) and the Brazilian Air Force (FAB). This event is studied in the context of the Vargas policies to mobilize the civilian population and to construct an internal front. The Estado Novo and the war constituted an important period in the affirmation of 'modern' nursing, as it was likewise vital in affirming nursing as a professional model for middle-class women. Nursing allowed the State to shape one of its most persuasive images: that of motherland. This image brought maternal care right to the battle front, helping make the war a collective experience that should bring together all men and women--all Brazilians--regardless of social stratum. The drive to forge a domestic front combined war mobilization efforts with efforts to win the middle classes over to the Estado Novo.

    Castaño, F.; Fernández, J. A.; Basterretxea, A. Longarte. F.; Sánchez Rayo, M. N.; Martínez, R.

    Entre las áreas hacia donde ha evolucionado la Química en los últimos años están los estudios de sistemas con especies reactivas de alta energía y los dominados por fuerzas intermoleculares débiles, con energías de unas pocas kcal/mol. En efecto, el estudio de las propiedades de los iones, comenzando por su relación con la molécula neutra de la que procede, la energía de ionización, los estados vibracionales y rotacionales, energías de enlace de Van der Waals entre el ión y una amplia variedad de otras moléculas, sus confórmeros o isómeros y sus reacciones o semi-reacciones químicas están en la raíz de la necesidad de la espectroscopía conocida como PFI-ZEKE, Pulsed Field Ionization-Zero Electron Kinetic Energy. Entre las aplicaciones que requieren estos conocimientos se encuentran la generación de plasmas para la fabricación de semiconductores, memorias magnéticas, etc, así como los sistemas astrofísicos, la ionosfera terrestre, etc. La espectroscopía ZEKE es una evolución de las de fluorescencia inducida por láser, LIF, ionización multifotónica acrecentada por resonancia, REMPI, con uno y dos colores y acoplada a un sistema de tiempo de vuelo, REMPI-TOF-MS, y las espectroscopías de doble resonancia IR-UV y UV-UV. Sus espectros y la ayuda de cálculos ab inicio permite determinar las energías de enlace de complejos de van der Waals en estados fundamental y excitados, identificar confórmeros e isómeros, obtener energías de ionización experimentales aproximadas (100 cm-1) y otras variables de interés. Al igual que con LIF, REMPI y dobles resonancias, es posible utilizar muestras gaseosas, pero los espectros están muy saturados de bandas y su interpretación es difícil o imposible. Se evitan estas dificultades estudiando las moléculas o complejos en expansiones supersónicas, donde la T de los grados de libertad solo alcanzan unos pocos K. Para realizar experimentos de ZEKE hay que utilizar una propiedad recientemente

    Maca (Lepidium meyenii Walp) polysaccharides (MP) with purity of 99.2% were obtained to investigate their structural characteristics and antifatigue effect in vivo. The physicochemical properties of MP were analyzed through high-performance gel filtration chromatography, IR, monosaccharide composition, methylation, GC-MS, and NMR analyses. The antifatigue effect of MP was evaluated by using a mouse weight-loaded swimming model. MP is an acidic heteropolysaccharide with an average molecular weight (M w ) of 793.5 kDa. It is composed of D-GalA: D-Glc: L-Ara: D-Man: D-Gal: L-Rha = 35.07:29.98:16.98:13.01:4.21:0.75 (mol, %). The findings revealed that MP contained β-1,3-Galp(A), β-1,3-Glcp, and α-1, 3-Manp linked alternatingly to form a backbone (5:4:1). MP (above mid-dosage 50 mg/kg bw/d) could effectively elongate swimming durations and accelerate average swimming speeds (within the 1st 5 min) of mice (P < 0.05) and improve the serous biochemical parameters of mice. Compared with the control model, high-dosage (100 mg/kg bw/d) MP treatment could significantly enhance glutathione peroxidase and creatine kinase activities (P < 0.05) and decreased lactate dehydrogenase activity (P < 0.01). High-dosage MP could significantly reduce the levels of blood urea nitrogen, lactic acid, and malondialdehyde (P < 0.05). MP is an acidic polysaccharide with a high D-GalA content, which could be responsible for the antifatigue effect of maca. © 2017 Institute of Food Technologists®.

  9. Water Vapor in Titan's Stratosphere from Cassini/CIRS Far-infrared Spectra

    Since the first detection of water vapor in Titan's stratosphere by disk-average observations from the Infrared Space Observatory (Coustenis et al. 1998) we report here the successful detection of stratospheric water vapor using the Cassini Composite Infrared Spectrometer (CIRS, Flasar et al. 2004). CIRS senses water emissions in the far infrared spectral region near 50 microns, which we have modeled using two independent radiative transfer codes (NEMESIS, Irwin et al 2008 and ART, Coustenis et al. 2007, 2010). From the analysis of nadir spectra we have derived a mixing ratio of (0.14 0.05) ppb at an altitude of 97 kilometers, which corresponds to an integrated (from 0 to 600 kilometers) surface normalized column abundance of (3.7 plus or minus 1.3) x 10(exp 14) molecules per square centimeter. In the latitude range 80 S to 30 N we see no evidence for latitudinal variations in these abundances within the error bars. Using limb observations, we obtained mixing ratios of (0.13 plus or minus 0.04) ppb at an altitude of 115 kilometers and (0.45 plus or minus 0.15) ppb at an altitude of 230 kilometers, confirming that the water abundance has a positive vertical gradient as predicted by photochemical models (e.g. Lara et al. 1996, Wilson and Atreya 2004, Horst et al. 2008); retrieved scaling factors (from approximately 0.1 to approximately 0.6) to the water profile suggested by these models show that water vapor is present in Titan stratosphere with less abundance than predicted.

    In children with sepsis, fluid overload as a result of an aggressive fluid replacement or excessive fluid administration may result in kidney impairment and increased mortality. Objective. To determine the association between fluid overload and the rate of kidney failure in a group of children with severe sepsis and septic shock. This was a prospective cohort study conducted in the intensive care unit of Hospital Universitario de Pediatría “Dr. Agustín Zubillaga” (Barquisimeto, Lara State, Venezuela), between March 2013 and May 2016, in children with severe sepsis or septic shock. One hundred and forty-nine patients were included in the analysis. Sepsis predominated in 59.7% of cases; patients' average age was 6.4 ± 3.3 years old, their average weight was 17.8 ± 3.6 kg, 30.2% had fluid overload, and overall mortality was 25.5%. Kidney failure occurred in 16.1% of cases. A binary logistic regression model was used to identify fluid overload (odds ratio [OR]: 1.5; 95% confidence interval [CI]: 1.2-4.9, p = 0.028) and shock for more than 2 days (OR: 1.7; 95% CI: 1.3-6.3, p = 0.039) as independent predictors of kidney failure. In addition, a significant increase in the risk of mortality among children with kidney failure and fluid overload was observed as per the Kaplan-Meier method (p= 0.019). Fluid overload and shock for more than 2 days increase the risk for kidney failure in critically ill children with severe sepsis and septic shock.

    Phenolic acids (chlorogenic, caffeic, p-coumaric, ferulic, sinapic, ellagic, and syringic acid) as well as syringaldehyde and juglone were identified in ripe fruits of 10 walnut cultivars: Adams, Cisco, Chandler, Franquette, Lara, Fernor, Fernette, Alsoszentivani 117 (A-117), Rasna, and Elit. Analyses were done using a high-performance liquid chromatograph equipped with a diode array detector. Significant differences in the contents of identified phenolics were observed among cultivars. Phenolics were determined separately in the kernel and in the thin skin of the walnut, termed the pellicle. Not only in the kernel but also in the pellicle did syringic acid, juglone, and ellagic acid predominate (average values of 33.83, 11.75, and 5.90 mg/100 g of kernel; and 1003.24, 317.90, and 128.98 mg/100 g of pellicle, respectively), and the contents of ferulic and sinapic acid (average values of 0.06 and 0.05 mg/100 g of kernel and 2.93 and 2.17 mg/100 g of pellicle, respectively) were the lowest in all cultivars. The highest differences in the sum of all identified phenolics were observed between Rasna and Fernette fruits; in Rasna there were >2-fold higher contents of identified phenolics in both kernel and pellicle. It was found that the walnut pellicle is the most important source of walnut phenolics. The ratio between the contents in pellicle and kernel varied by at least 14.8-fold for caffeic acid (cv. Adams) and by up to 752.0-fold for p-coumaric acid (cv. Elit).

    Assessing maternal perception of their children's nutritional status and identifying associated factors. A cross-sectional study conducted in a small municipality with 342 children less than 3 years of age treated in Basic Health Units of São Paulo. Nutritional status was classified in percentiles of body mass index for age and maternal perception was assessed using the scale of verbal descriptors (very thin, thin, healthy weight, fat, very fat). Logistic regression was used to identify the associatedfactors. 44.7% of maternal perception was found to beinadequate. Mothers of overweight (OR = 11.8, 95% CI: 6.4-21.7) and underweight (OR = 5.5; 95% CI: 1.9-16.2) children had a higher chance of having inadequate perception, similar to mothers of children over 24 months of age (OR = 2.9; 95% CI: 1.4-6.0). For effective child care in primary care, healthcare professionals should consider maternal perception and helpmothers to identify the nutritional status of children in childcare consultations and growth monitoring.

    A marine campaign to compute the sea surface data along the Spanish Mediterranean coastline and Balearic Islands is being prepared for 2013. Jason-2 (period ~10 days) and Saral/AltiKa (period of 35 days and expected launch in 2012) altimetric data and on-board GPS data will be used. Many GPS Buoy sessions along the ship route will be performed.Sea height estimates (instantaneous and mean sea levels) will be compared. Recently some geodetic improvements has been made in specific coastal spanish sites in the NW Mediterranean Sea for monitoring sea level. The goal is to maintain and improve the quality of the observation of the sea level change in the three sites. The information is coming from Puertos del Estado www.puertos.es L'Estartit tide gauge has been co-located with geodetic techniques (GPS measurements of XU, Utilitary Network, and XdA, Levelling Network,) and it is tied to the SPGIC (Integrated Geodetic Positioning System of Catalonia) project of the Cartographic Institute of Catalunya (ICC). In the past three calibration campaigns for Topex/Poseidon and Jason-1 in March 1999, August 2000 and July 2002 near Cape of Begur. At Barcelona harbour there is one MIROS radar tide gauge belonging to Puertos del Estado (Spanish Harbours).The radar sensor is over the water surface, on a L-shaped structure which elevates it a few meters above the quay shelf. 1-min data are transmitted to the ENAGAS Control Center by cable and then sent each 1 min to Puertos del Estado by e-mail. The information includes wave forescast (mean period, significant wave height, sea level, etc.This sensor also measures agitation and sends wave parameters each 20 min. There is a GPS station Leica Geosystems GRX1200 GG Pro and antenna 1202. Bathymetric campaigns inside the harbour have been made. At Ibiza site new measurements and levelling between the GPS reference station and a Radar MIROS, both from Puertos del Estado, has been made recently. A calibration campaign for Jason-1 was made in

    The B[e] phenomenon is related to certain peculiar features observed in the spectrum of some B stars, which are mainly linked to the physical conditions of their circumstellar medium. As these stars are embedded in dense and optically thick circumstellar media, the determination of the spectral type and luminosity class of the central objects is quite difficult. As a consequence, their evolutionary stage and distances present huge uncertainties. In this work we study 4 B[e] stars and discuss their stellar fundamental parameters and evolutionary stages using the BCD spectrophotometric system. FULL TEXT IN SPANISH

    Objetivos: los objetivos de este estudio fueron analizar el nivel nutricional en una población de niños y adolescentes colombianos y determinar la posible relación entre el nivel nutricional y el estado nutricional según el índice de masa corporal (IMC) y la circunferencia de cintura (CC).Material y métodos: estudio transversal en 6.383 niños y adolescentes de entre 9 y 17,9 años de edad, de Bogotá, Colombia. Se aplicó de manera autodiligenciada el cuestionario Krece Plus validado en el estudio enKid como indicador del nivel nutricional con las categorías alto (test ≥ 9), medio (test 6-8) y bajo (test ≤ 5). Se tomaron medidas de peso, talla, CC, y se calculó el IMC como marcadores del estado nutricional.Resultados: de la población general, el 57,9% eran chicas (promedio de edad 12,7 ± 2,3 años). En todas las categorías del IMC, más del 50% de chicos y chicas siguen una dieta de muy baja calidad, que empeora progresivamente con el avance en edad. En ambos sexos, se observaron tendencias entre un nivel nutricional muy bajo con el desarrollo de sobrepeso. Asimismo, la obesidad abdominal por CC se relacionó con una puntuación baja en el Krece Plus en ambos sexos.Conclusiones: en escolares de Bogotá, una dieta de muy baja calidad se relacionó con alteraciones del estado nutricional (IMC y CC), especialmente entre chicas y adolescentes. Estos resultados deben alentar el desarrollo de intervenciones orientadas a mejorar los hábitos nutricionales entre los escolares colombianos.

    Resumen El VIH es un problema de salud importante dentro de la comunidad latina de los Estados Unidos. Gracias a los esfuerzos de prevención, los niveles de contagio entre los latinos se han mantenido estables por más de una década. Sin embargo, esta población sigue siendo afectada a niveles muy altos, en particular entre hombres que tienen sexo con hombres (HSH), de origen latino y que hablan principalmente el idioma español. Existen varios factores que contribuyen a la transmisión del VIH entre esta población, como son: el uso de drogas; la violencia dentro de la pareja; la presencia de infecciones de transmisión sexual; relaciones sexuales sin protección, dentro y fuera de la pareja; el evadir la búsqueda de recursos (prueba y tratamiento adecuado) por temor a ser discriminado o por su estatus migratorio; la escasez de recursos económicos o estado de pobreza y los patrones relacionados a la migración. En particular, Investigaciones Epidemiológicas de Comportamientos han determinado: cómo algunas dinámicas en parejas están directamente asociadas a los comportamientos sexuales de riesgos. En consecuencia, es necesaria mayor investigación para identificar esas dinámicas, y a su vez, realizar intervenciones dirigidas a la reducción de conductas de riesgo enfocadas en parejas de hombres del mismo sexo. En este escrito, se describe la importancia del uso de las relaciones de pareja como estrategia en la reducción de la trasmisión del VIH/SIDA en HSH de origen latino y que hablan principalmente el idioma español en los Estados Unidos.

  14. The effects of variable front persistence and intensity on mesopelagic fish communities: a comparison of three fronts in the California Current Ecosystem

    NASA Astrophysics Data System (ADS)

    Netburn, A. N.; Koslow, J. A.

    2016-02-01

    Although the strong physical gradients at fronts are primarily realized in the epipelagic, the biological impacts of frontal ecosystems can extend into mesopelagic waters. In 2008, Lara-Lopez et al. (2012) observed a significant shift in total biomass and community composition of migrating mesopelagic fishes at a strong persistent front off of the Pt. Conception area of the southern California Current Ecosystem. Through the California Current Ecosystem Long-Term Ecological Research Program, two additional intensive sampling cruises have been conducted on frontal systems in the general region. In 2011 and 2012, paired day and night midwater Matsuda-Oozeki-Hu trawls were conducted at stations located on either side of the fronts and at the fronts themselves, a suite of concurrent observations of the physical environment measured, and lower trophic levels sampled. Using satellite imagery, we estimate front duration of each of the 2008, 2011, and 2012 fronts, and investigate changes to the relative abundance and community composition across these systems, comparing the resolved patterns in 2011 and 2012 to those published from 2008. Results of this work will help address the questions: (1) What are the timescales required for front presence to impact mesopelagic fish communities? (2) Do different types of frontal systems (e.g., an eddy front vs. a "classic" front) result in different patterns of mesopelagic fish abundance and community composition? These answers will provide insight into the mechanisms of accumulation of fishes at fronts. As many mesopelagic fishes are important forage species for oceanic predators, understanding their response to the high productivity frontal systems is key to understanding ecosystem-wide impacts of fronts.

    Radial basis neural networks (RBNNs) were developed and evaluated for discrimination of specimens of 'aguardiente de Cocuy', a spirituous beverage produced in the northwestern region of Venezuela. The beverage is distilled from the must of Agave cocui Trelease in an artisanship fashion with little quality control. Forty specimens, with known concentrations of copper, iron, and zinc, were used in this study. The specimens were previously collected in various locations around Sucre Municipality (Falcón State) and Urdaneta Municipality (Lara State). The normalized concentrations of these elements served as indirect descriptors of origin (input data). They were presented to the neural networks through 1-3 input nodes in seven different combinations. In addition, two categories (two collection sites) and four categories (two collection sites+two manufacturing conditions) were designated as output data, in order to assess the impact of such selection on the discrimination performance. The overall performance of the four-category RBNNs was as follows (the input data is indicated in parentheses): (Cu-Fe)>(Cu-Zn)>(Cu)>(Zn)>(Fe-Zn)>(Cu-Fe-Zn)>(Fe). In this case, the highest percentage of correct hits was 82.5%. For the two-category RBNNs, the performance decreased as indicated below: (Cu)>(Cu-Fe)>(Cu-Zn)>(Fe-Zn)>(Zn) approximately (Cu-Fe-Zn)>(Fe). The reduction in the number of categories led to an increase in the discrimination performance of all the RBNNs, the best of which was 90.0%. The possibility of discriminating specimens of 'aguardiente de Cocuy' with such an accuracy, based on a single-element determination, is particularly attractive as it would result in a reduction of analysis' costs and laboratory's response time.

    Esta investigación tiene como objetivo investigar el efecto que la disolución de las uniones consensuales tiene en los niveles de soltería que proporciona el Censo de Población, niveles derivados de la variable estado civil. Para ello comparamos los datos censales con los de la Encuestas de Demografía y Salud (de ahora en adelante DHS) en aquellos países y años para los que disponemos de ambas fuentes en el mismo año o años adyacentes (Bolivia, Brasil, Colombia y Perú). Los resultados muestran claramente que las proporciones de nunca unidas derivadas de la variable censal ’Estado civil’ son sistemáticamente más elevadas que las estimadas a partir de las DHS. La razón de esta sobreestimación obedece al hecho de que personas que estuvieron en unión libre en el pasado se declaran solteras en el momento del Censo. La elevada proporción de mujeres solteras que tienen hijos según el Censo es una prueba de ello y a su vez una solución efectiva para corregir el sesgo. PMID:25593515

Si los eventos prodnctores de radiaci6n gravitatoria han venido ocurriendo desde Ia epoca de Ia formaci6n de las galaxias, cuando menos, sus efectos cosmol6gicos pueden ser tomados en cuenta con simplicidad y elegancia al representar la producci6n de radiaci6n y, por consiguiente, su interacci6n con materia ordinaria fenomenol6gicamente a trave's de una ecuaci6n de estado politr6pica, como lo hemos mostrado en otros trabajos. Presentamos en este articulo resultados nunericos de este modelo. ABSTRACT A common believe in cosmology is that gravitational radiation in considerable quantities is being produced within the galaxies. Ifgravitational radiation production has been running since the galaxy formation epoch, at least, its cosmological effects can be assesed with simplicity and elegance by representing the production of radiation and, therefore, its interaction with ordinary matter phenomenologically through a polytropic equation of state as shown already elsewhere. We present in this paper the numerical results of such a model. K words: COSMOLOGY - GRAVITATION

    This paper reports that like so many other countries, Argentina is in the throes of privatization and restructuring of its economic programs. This has had a direct effect on the LPG industry. Argentina is a country with many natural resources. However, natural gas and crude, while present, are not in abundance. Imports of these and their associated products are needed to satisfy the growing need of the population from time to time. This is especially true with LPGs. Production of the fuel averages about 1 million tons, not enough to satisfy internal needs in the winter but enough to permitmore » some exports in the summer to nearby Brazil. The Country's Congress approved a plan to sell-off or lease parts of the natural gas distribution network and other businesses of Gas del Estado. Subsequent new legislation has called for ten new natural gas distribution zones. Included in the sell-off is the company's propane distribution division. What is left of Gas del Estado and YPF will become a corporation in the true sense of the word. Stocks in YPF are to be sold to the public.« less

    Objetivo: identificar los hábitos alimentarios de adolescentes embarazadas en cuatro estados civiles diferentes: casada, cohabita con una pareja, soltera sin pareja y soltera con una pareja. Métodos: en estudio transversal, se incluyeron 321 adolescentes embarazadas de 13-19 años que acudieron al Hospital Civil de Guadalajara Dr. Juan I Menchaca, Guadalajara (Jalisco, México). Se encontraban sanas, en cualquier trimestre del embarazo y pertenecían a un nivel socioe-conómico bajo o medio-bajo. El estado civil se estratificó en: casadas; en unión libre; soltera con una pareja y soltera sin pareja. Se incluyeron datos socio-demográficos, económicos y de hábitos de alimentación. Se utilizaron pruebas de ANOVA, pruebas post-hoc para Chi 2 , razón de momios y modelos de regresión logística. Resultados: la frecuencia de las adolescentes casadas fue de 9,3%, 59,8% en unión libre, 15,3% eran solteras sin pareja y 15,6% solteras con pareja. La baja escolaridad (RM 2,6 [1,5-4,4]) y la ocupación en el hogar (RM 4,47 [1,99-10,0]) predominaron entre las adolescentes en unión libre; la ocupación en el hogar (RM 0,28 [0,127-0,61]) y cenar sin compañía (RM 4,12 [1,62-10,8]) fueron significativamente más frecuentes en adolescentes sin pareja. El consumo de verduras fue menor en las adolescentes casadas y en quienes cohabitaban con pareja; el consumo de frijoles y pan dulce fue menor en adolescentes embarazadas casadas. Conclusión: debido a que ciertas variables y hábitos de alimentación mostraron diferencias entre los grupos es pertinente analizar las adolescentes embarazadas de acuerdo a su estado civil.

  12. Changes in Landscape-level Carbon Balance of an Arctic Coastal Plain Tundra Ecosystem Between 1970-2100, in Response to Projected Climate Change

    Northern permafrost regions are estimated to cover 16% of the global soil area and account for approximately 50% of the global belowground organic carbon pool. However, there are considerable uncertainties regarding the fate of this soil carbon pool with projected climate warming over the next century. In northern Alaska, nearly 65% of the terrestrial surface is composed of polygonal tundra, where geomorphic land cover types such as high-, flat-, and low-center polygons influence local surface hydrology, plant community composition, nutrient and biogeochemical cycling, over small spatial scales. Due to the lack of representation of these fine-scale geomorphic types and ecosystem processes, in large-scale terrestrial ecosystem models, future uncertainties are large for this tundra region. In this study, we use a new version of the terrestrial ecosystem model (TEM), that couples a dynamic vegetation model (in which plant functional types compete for water, nitrogen, and light) with a dynamic soil organic model (in which temperature, moisture, and associated organic/inorganic carbon and nitrogen pools/fluxes vary together in vertically resolved layers) to simulate ecosystem carbon balance. We parameterized and calibrated this model using data specific to the local climate, vegetation, and soil associated with tundra geomorphic types. We extrapolate model results at a 1km2 resolution across the ~1800 km2 Barrow Peninsula using a tundra geomorphology map, describing ten dominant geomorphic tundra types (Lara et al. submitted), to estimate the likely change in landscape-level carbon balance between 1970 and 2100 in response to projected climate change. Preliminary model runs for this region indicated temporal variability in carbon and active layer dynamics, specific to tundra geomorphic type over time. Overall, results suggest that it is important to consider small-scale discrete polygonal tundra geomorphic types that control local structure and function in regional

  13. Post-Hartree-Fock studies of the He/Mg(0001) interaction: Anti-corrugation, screening, and pairwise additivity

    The adsorption of noble gases on metallic surfaces represents a paradigmatic case of van-der-Waals (vdW) interaction due to the role of screening effects on the corrugation of the interaction potential [J. L. F. Da Silva et al., Phys. Rev. Lett. 90, 066104 (2003)]. The extremely small adsorption energy of He atoms on the Mg(0001) surface (below 3 meV) and the delocalized nature and mobility of the surface electrons make the He/Mg(0001) system particularly challenging, even for state-of-the-art vdW-corrected density functional-based (vdW-DFT) approaches [M. P. de Lara-Castells et al., J. Chem. Phys. 143, 194701 (2015)]. In this work, we meet thismore » challenge by applying two different procedures. First, the dispersion-corrected second-order Möller-Plesset perturbation theory (MP2C) approach is adopted, using bare metal clusters of increasing size. Second, the method of increments [H. Stoll, J. Chem. Phys. 97, 8449 (1992)] is applied at coupled cluster singles and doubles and perturbative triples level, using embedded cluster models of the metal surface. Both approaches provide clear evidences of the anti-corrugation of the interaction potential: the He atom prefers on-top sites, instead of the expected hollow sites. This is interpreted as a signature of the screening of the He atom by the metal for the on-top configuration. The strong screening in the metal is clearly reflected in the relative contribution of successively deeper surface layers to the main dispersion contribution. Aimed to assist future dynamical simulations, a pairwise potential model for the He/surface interaction as a sum of effective He–Mg pair potentials is also presented, as an improvement of the approximation using isolated He–Mg pairs.« less

  14. Changes in Cardiac Variability after REM Sleep Deprivation in Recurrent Nightmares

    2010-01-01

    Study Objectives: To assess whether dysfunctional autonomic regulation during REM sleep as indexed by heart rate variability (HRV) is a pathophysiological factor in frequent nightmares (NMs). Design: Monitoring with polysomnography (PSG) and electrocardiography (ECG) for 3 consecutive nights: Night 1 (N1), adaptation night; N2, administration of partial REM sleep deprivation; N3, recovery night. Differences between NM and control (CTL) groups assessed for ECG measures drawn from wakefulness, REM sleep, and Stage 2 sleep on both N1 and N3. Setting: Hospital-based sleep laboratory Participants: Sixteen subjects with frequent NMs ( ≥ 1 NM/week; mean age = 26.1 ± 8.7 years) but no other medical or psychiatric disorders and 11 healthy comparison subjects ( < 1 NM/month; mean age = 27.1±5.6 years). Results: NM and CTL groups differed on 2 REM sleep measures only on N1; the NM group had longer REM latencies and REM/NREM cycle durations than did the CTL group. No differences were found on time domain and absolute frequency domain ECG measures for either N1 or N3. However, altered HRV for the NM group was suggested by significantly higher LFnu, lower HFnu, and higher LF/HF ratio than for the CTL group. Conclusions: Results are consistent with a higher than normal sympathetic drive among NM subjects which is unmasked by high REM sleep propensity. Results also support a growing literature linking anxiety disorders of several types (panic disorder, posttraumatic stress disorder (PTSD), generalized anxiety disorder) to altered HR variability.

    The postnatal period is associated with many new needs for mothers. The aim of this study was to find technological solutions that meet the needs of mothers during the year following childbirth. Two co-creation workshops were undertaken with parents and professionals. The aim of the first workshop was to create a list of all the criteria the proposed solution would have to address to meet the needs of mothers after childbirth. The aim of the second workshop was to create solutions in response to the criteria selected during the first workshop. Parents and health professionals want solutions that include empathy (ie, to help fight against the feelings of abnormality and loneliness), that help mothers in daily life, that are personalized and adapted to different situations, that are educational, and that assures some continuity in their contact with health professionals. In practice, we found that parents and professionals think the solution should be accessible to everyone and available at all times. To address these criteria, technology experts proposed different solutions, such as a forum dedicated to the postpartum period that is supervised by professionals, a centralized website, a system of videoconferencing, an online exchange group, a "gift voucher" system, a virtual reality app, or a companion robot. The human component seems to be very important during the postnatal period. Nevertheless, technology could be a great ally in helping mothers during the postpartum period. Technology can help reliably inform parents and may also give them the right tools to find supportive people. However, these technologies should be tested in clinical trials. ©Justine Slomian, Patrick Emonts, Lara Vigneron, Alessandro Acconcia, Jean-Yves Reginster, Mina Oumourgh, Olivier Bruyère.

    Here we report the measurement of water vapor in Titan's stratosphere using the Cassini Composite Infrared Spectrometer (CIRS, Flasar, F.M. et al. [2004]. Space Sci. Rev. 115, 169-297). CIRS senses water emissions in the far infrared spectral region near 50 μm, which we have modeled using two independent radiative transfer codes (NEMESIS (Irwin, P.G.J. et al. [2008]. J. Quant. Spectrosc. Radiat. Trans. 109, 1136-1150) and ART (Coustenis, A. et al. [2007]. Icarus 189, 35-62; Coustenis, A. et al. [2010]. Icarus 207, 461-476). From the analysis of nadir spectra we have derived a mixing ratio of 0.14 ± 0.05 ppb at an altitude of 97 km, which corresponds to an integrated (from 0 to 600 km) surface normalized column abundance of 3.7 ± 1.3 × 1014 molecules/cm2. In the latitude range 80°S to 30°N we see no evidence for latitudinal variations in these abundances within the error bars. Using limb observations, we obtained mixing ratios of 0.13 ± 0.04 ppb at an altitude of 115 km and 0.45 ± 0.15 ppb at an altitude of 230 km, confirming that the water abundance has a positive vertical gradient as predicted by photochemical models (e.g. Lara, L.M., Lellouch, F., Lopez-Moreno, J.J., Rodrigo, R. [1996]. J. Geophys. Res. 101(23), 261; Wilson, E.H., Atreya, S.K. [2004]. J. Geophys. Res. 109, E6; Hörst, S.M., Vuitton, V., Yelle, R.V. [2008]. J. Geophys. Res., 113, E10). We have also fitted our data using scaling factors of ˜0.1-0.6 to these photochemical model profiles, indicating that the models over-predict the water abundance in Titan's lower stratosphere.

    Ras proteins regulate cell survival, growth, differentiation, blood pressure, and fibrosis in some organs. We have demonstrated that H- ras gene deletion produces mice hypotension via a soluble guanylate cyclase-protein kinase G (PKG)-dependent mechanism. In this study, we analyzed the consequences of H- ras deletion on cardiac remodeling induced by continuous angiotensin II (AngII) infusion and the molecular mechanisms implied. Left ventricular posterior wall thickness and mass and cardiomyocyte cross-sectional area were similar between AngII-treated H-Ras knockout (H -ras -/- ) and control wild-type (H -ras +/+ ) mice, as were extracellular matrix protein expression. Increased cardiac PKG-Iβ protein expression in H -ras -/- mice suggests the involvement of this protein in heart protection. Ex vivo experiments on cardiac explants could support this mechanism, as PKG blockade blunted protection against AngII-induced cardiac hypertrophy and fibrosis markers in H -ras -/- mice. Genetic modulation studies in cardiomyocytes and cardiac and embryonic fibroblasts revealed that the lack of H-Ras down-regulates the B-RAF/MEK/ERK pathway, which induces the glycogen synthase kinase-3β-dependent activation of the transcription factor, cAMP response element-binding protein, which is responsible for PKG-Iβ overexpression in H -ras -/- mouse embryonic fibroblasts. This study demonstrates that H- ras deletion protects against AngII-induced cardiac remodeling, possibly via a mechanism in which PKG-Iβ overexpression could play a partial role, and points to H-Ras and/or downstream proteins as potential therapeutic targets in cardiovascular disease.-Martín-Sánchez, P., Luengo, A., Griera, M., Orea, M.

    Purpose The aim was to assess atrial fibrillation (AF) and vulnerability in Wolff-Parkinson-White (WPW) syndrome patients using two-dimensional speckle tracking echocardiography (2D-STE). Methods All patients were examined via transthoracic echocardiography and 2D-STE in order to assess atrial function 7 days before and 10 days after RF catheter ablation. A postoperative 3-month follow-up was performed via outpatient visit or telephone calls. Results Results showed significant differences in both body mass index (BMI) and supraventricular tachycardia (SVT) duration between WPW patients and DAVNP patients (both P<0.05). Echocardiography revealed that the maximum left atrial volume (LAVmax) and the left ventricular mass index (LVMI) in diastole increased noticeably in patients with WPW compared to patients with DAVNP both before and after ablation (all P<0.05). Before ablation, there were obvious differences in the levels of SRs, SRe, and SRa from the 4-chamber view (LA) in the WPW patients group compared with patients in the DAVNP group (all P<0.05). In the AF group, there were significant differences in the levels of systolic strain rate (SRs), early diastolic strain rate (SRe), and late diastolic strain rate (SRa) from the 4-chamber view (LA) both before and after ablation (all P<0.05). In the non-AF group, there were decreased SRe levels from the 4-chamber view (LA/RA) pre-ablation compared to post-ablation (all P<0.05). Conclusion Our findings provide convincing evidence that WPW syndrome may result in increased atrial vulnerability and contribute to the development of AF. Further, RF catheter ablation of AAV pathway can potentially improve atrial function in WPW syndrome patients. Two-dimensional speckle tracking echocardiography imaging in WPW patients would be necessary in the evaluation and improvement of the overall function of RF catheter ablation in a long-term follow-up period.

P. de Lara-Castells et al., J. Chem. Phys. 143, 194701 (2015)]. In this work, we meet this challenge by applying two different procedures. First, the dispersion-corrected second-order Möller-Plesset perturbation theory (MP2C) approach is adopted, using bare metal clusters of increasing size. Second, the method of increments [H. Stoll, J. Chem. Phys. 97, 8449 (1992)] is applied at coupled cluster singles and doubles and perturbative triples level, using embedded cluster models of the metal surface. Both approaches provide clear evidences of the anti-corrugation of the interaction potential: the He atom prefers on-top sites, instead of the expected hollow sites. This is interpreted as a signature of the screening of the He atom by the metal for the on-top configuration. The strong screening in the metal is clearly reflected in the relative contribution of successively deeper surface layers to the main dispersion contribution. Aimed to assist future dynamical simulations, a pairwise potential model for the He/surface interaction as a sum of effective He-Mg pair potentials is also presented, as an improvement of the approximation using isolated He-Mg pairs.

    2017-01-01

    RESUMEN En México, las transferencias formales e informales destinadas al apoyo de las personas adultas mayores son diversificadas. En este documento se analizan la tendencia nacional y los resultados de un estudio centrado en la entidad federativa de Guanajuato. La distribución de los apoyos confirma que las transferencias hechas por el sistema de seguridad social tienen un sesgo urbano y que las transferencias formales del gobierno federal se orientan a las áreas menos urbanizadas, particularmente las zonas rurales. A pesar de las transferencias formales (esporádicas e insuficientes), las necesidades económicas y de salud de las personas mayores persisten y ello lleva a que sus familiares realicen transferencias informales de naturaleza ascendente. En México —y más concretamente en Guanajuato— el apoyo de quienes residen con la persona mayor tiene un significativo peso, y lo contrario sucede con el de quienes han migrado. A partir de este material, se analiza el rol que, de acuerdo a su cohorte y su condición migratoria, desempeñan los descendientes. En todo caso, queda de manifiesto que, en cada entidad nacional, las dinámicas de transferencias intergeneracionales son de diversos tipos. PMID:29375179

    2014-01-01

    Introducción: La cirugía de los trastornos del comportamiento (CTC) se está convirtiendo en un tratamiento más común desde el desarrollo de la neuromodulación. Métodos: Este artículo es una revisión no sistemática de la historia, indicaciones actuales, técnicas y blancos quirúrgicos de la CTC. Dividimos su historia en 3 eras: la primera comienza en los inicios de la psicocirugía y termina con el desarrollo de las tícnicas estereotácticas, cuando comienza la segunda era. Ésta se caracteriza por la realización de lesiones estereotácticas. Nos encontramos transitando la tercera era, que comienza cuando la estimulación cerebral profunda (ECP) comienza a ser usada en CTC. Resultados: A pesar de los errores graves cometidos en el pasado, hoy en día, la CTC está renaciendo. Los trastornos psiquiátricos que se más frecuentemente se tratan con cirugía son: depresión refractaria, trastorno obsesivo-compulsivo y síndrome de Tourette. Además, algunos pacientes con agresividad fueron tratados quirúrgicamente. Hay varios blancos estereotácticos descriptos para estos trastornos. La estimulación vagal puede ser usada también para depresión. Conclusión: Los resultados de la ECP en estos trastornos parecen alentadores. Sin embargo, se necesitan más estudios randomizados para establecer la efectividad de la CTC. Debe tenerse en cuenta que una apropiada selección de pacientes nos ayudará a realizar un procedimiento más seguro así como también a lograr mejores resultados quirúrgicos, conduciendo a la CTC a ser más aceptada por psiquiatras, pacientes y sus familias. Se necesita mayor investigación en varios temas como: fisiopatología de los trastornos del comportamiento, indicaciones de CTC y nuevos blancos quirúrgicos. PMID:25165612

    2014-08-01

    A Astronomia é um tema que sempre exerceu fascínio sobre as pessoas de um modo geral. Conhecer e estudar o que há nos “céus”, além de nossos olhos, continua sendo instigador e de grande interesse. Baseado nestas justificativas desenvolveu-se uma pesquisa de Doutorado, na qual, o objetivo principal foi investigar sobre a presença dos conteúdos de Astronomia nas Propostas Curriculares da região Sul do Brasil, a saber, os estados de Paraná, Rio Grande do Sul e Santa Catarina e, posterior comparação com os Parâmetros Curriculares Nacionais (PCN) que trazem propostas de conteúdos para toda a Educação Básica brasileira. Tal investigação pautou-se na abordagem de caráter qualitativo e utilizouse para tal da Análise de Conteúdos (Bardin, 2011), que possibilitou a construção de quatro categorias, nas quais os conteúdos astronômicos foram agrupados: Terra, Sistema Solar, Via Láctea e Universo. Após a leitura, coleta de dados, construção de categorias, observou-se a dicotomia na apresentação destes conteúdos. As propostas curriculares analisadas foram as de Geografia, Ciências e Física dos estados do Paraná (2008), Rio Grande do Sul (2009) e de Santa Catarina (1998), responsáveis pelo trabalho com Astronomia nestes estados. No Ensino Fundamental, a proposta curricular do estado do Paraná apresenta conteúdos ligados à Astronomia desde o sexto ano até o nono ano, como conteúdo do primeiro bimestre, o que também é apresentado na proposta curricular do estado do Rio Grande do Sul, porém, este, não divide os conteúdos por bimestre e nem por ano, mas por ciclos, sexto e sétimo anos como primeiro ciclo e oitavo e nono anos como segundo ciclo, deixando livre para o professor estruturar sua sequência de conteúdos. A proposta curricular de Santa Catarina não apresenta estes conteúdos de maneira explícita, não divide dos conteúdos nem por ano, nem por série, traz uma sequência de conteúdos para serem trabalhados ao longo dos

    NASA Astrophysics Data System (ADS)

    Coimbra, Artur Emanuel Cardoso

    Desde cedo que a comunidade cientifica compreendeu que gases nobres em liquido sao excelentes meios de deteccao de radiacao, combinando a sua elevada densidade, elevado grau de homogeneidade e de elevado rendimento de cintilacao. Para alem destas caracteristicas inerentes, estes tem a potencialidade de fornecer ambos sinais de ionizacao - criando electroes livres - e cintilacao em resposta a interaccao com radiacao ionizante e, tendo em vista a sua aplicacao em experiencias de eventos raros relacionados com fisica de neutrinos ou materia-escura, a capacidade de autoblindagem garante a exclusao de eventos induzidos por radiacao de fundo. O facto de nao absorverem a sua propria luz, emergente dos eventos de cintilacao, permite a expansao deste tipo de detectores ate grandes volumes, sendo que as colaboracoes mais recentes propoem detectores com dezenas de toneladas de xenon em estado liquido. As experiencias actuais que usam gases nobres em estado liquido empregam xenon ou argon numa so fase (estado liquido) ou em dupla-fase (estado liquido + gasoso) e as suas aplicacoes abrangem desde as ja referidas experiencias de procura de eventos raros, passando por imagiologia medica tais como detectores de radiacao gama para PET ou câmaras Compton "3-gamma" em combinacao com PET, passando tambem por aplicacoes de seguranca como sistemas de inspeccao para deteccao de material fissil e, finalmente, em câmaras Compton para aplicacoes de astrofisica. Em ambas as configuracoes a leitura dos sinais de cintilacao e geralmente feita atraves de um grande numero de dispendiosos fotomultiplicadores de vacuo agrupados. A presente tese de doutoramento e dedicada aos fotomultiplicadores gasosos de grande area para aplicacoes criogenicas desenvolvidos no contexto do programa doutoral, tendo em vista a sua eventual aplicacao como um dispositivo complementar aos metodos existentes de deteccao de cintilacao, para aplicacao em futuras experiencias de grande escala.

    ``Black widow'' systems are located in a well determined region of the plane (where is the mass of the pulsar companion and is the orbital period of the system). An attempt has been made to understand which are the mechanisms that lead to companions of ``black widows'' to be located in this region; since standard binary evolution does not provide a satisfactory response. From our evolutionary calculations; we study the path performed in the plane by a binary system to reach the state of ``black widow''. We also discuss whether there is a connection between ``redbacks'' and ``black widows''. FULL TEXT IN SPANISH

After the replacement of the first collimator lens; broken in 2012; a problem persisted in the optical alignment. The troubleshooting will require a new instrument refurbishing schedule; meanwhile; the available operation modes are limited to direct image and longslit spectroscopy. We found that the direct image () achieves its highest quality (0.4'') only in the inner 3' of the field and resolution drops toward the spectrum ends. The longslit mode provides for the / ranges; and for the R3k grism in the ranges ; or . We also determine the uncertainties for emission line kinematics; and study the relative flexion between the guiding system; the slit and the detector. FULL TEXT IN SPANISH

    In Argentina, the State financed, built, and ran government-own railroads based on recourse to subsidies until the first Yrigoyen administration (1916-1922), which introduced changes and shifted the direction of rail policy somewhat. The Ferrocarriles del Estado contributed to the development of science, created a demand for professionals which helped form the professional engineering field, and, by linking the capitals of central and northern provinces, facilitated both communications and scientific tasks themselves, especially research into diseases endemic to the country.

  12. An optimized full-configuration-interaction nuclear orbital approach to a ``hard-core'' interaction problem: Application to (3He)N-Cl2(B) clusters (N<=4)

    2009-11-01

    An efficient full-configuration-interaction nuclear orbital treatment has been recently developed as a benchmark quantum-chemistry-like method to calculate ground and excited "solvent" energies and wave functions in small doped ΔEest clusters (N ≤4) [M. P. de Lara-Castells, G. Delgado-Barrio, P. Villarreal, and A. O. Mitrushchenkov, J. Chem. Phys. 125, 221101 (2006)]. Additional methodological and computational details of the implementation, which uses an iterative Jacobi-Davidson diagonalization algorithm to properly address the inherent "hard-core" He-He interaction problem, are described here. The convergence of total energies, average pair He-He interaction energies, and relevant one- and two-body properties upon increasing the angular part of the one-particle basis set (expanded in spherical harmonics) has been analyzed, considering Cl2 as the dopant and a semiempirical model (T-shaped) He-Cl2(B) potential. Converged results are used to analyze global energetic and structural aspects as well as the configuration makeup of the wave functions, associated with the ground and low-lying "solvent" excited states. Our study reveals that besides the fermionic nature of H3e atoms, key roles in determining total binding energies and wave-function structures are played by the strong repulsive core of the He-He potential as well as its very weak attractive region, the most stable arrangement somehow departing from the one of N He atoms equally spaced on equatorial "ring" around the dopant. The present results for N =4 fermions indicates the structural "pairing" of two H3e atoms at opposite sides on a broad "belt" around the dopant, executing a sort of asymmetric umbrella motion. This pairing is a compromise between maximizing the H3e-H3e and the He-dopant attractions, and suppressing at the same time the "hard-core" repulsion. Although the He-He attractive interaction is rather weak, its contribution to the total energy is found to scale as a power of three and it thus

    Tláloc, Tlacotenco, Cuauhtzin, Hijo del Cuauhtzin, Teuhtli, and Ocusacayo monogenetic volcanoes located within the Sierra del Chichinautzin Volcanic Field (SCVF) at the southern margin of Mexico City were studied to further refine attendant volcanic hazards in this heavily populated region. Based on fieldwork and Landsat imagery interpretation, a geologic map was produced, morphometric parameters characterizing the cones and lava flows were determined, and the areal extent and volumes of erupted products were estimated. The longest lava flow was produced by Tlacotenco and reached 9.5 km from its source; total areas covered by lava flows from each eruption range between 12.8 km 2 (Tlacotenco) and 54.4 km 2 (Tláloc); and total erupted volumes range between 0.26 and 1.36 km 3 per volcano. Radiocarbon measurements of a paleosol underneath an ash layer from the Tláloc scoria cone yielded an age of 6200 years BP, while charcoal found within block-and-ash flow and lahar deposits from Cuauhtzin dome yielded ages of 7360 and 8225 years BP, respectively. The Tlacotenco dacite lava flow overlies Popocatépetl's Tutti Frutti Plinian pumice fall deposit dated at 14,000 years BP and is therefore younger than this prominent stratigraphic marker. On the other hand, Teuhtli and Hijo del Cuauhtzin scoria cones and the Ocusacayo andesite lava flows are overlain by the Tutti Frutti and therefore older than 14,000 years BP. These new dates together with other published dates for scoria cones in the SCVF imply that the previously determined recurrence interval during the Holocene for monogenetic eruptions in the SCVF of <1700 years [Siebe, C., Rodríguez-Lara, V., Schaaf, P., Abrams, M., 2004a. Radiocarbon ages of Holocene Pelado, Guespalapa, and Chichinautzin scoria cones, south of Mexico_City: implications for archaeology and future hazards. Bull. Volcanol. 66, 203-225.] needs to be corrected to <1250 years. This means that the time of quiescence since the last eruption of the SCVF

  15. Thermodynamics of alpha-Cyclodextrin-p-Nitrophenyl Glycoside Complexes. A Simple System To Understand the Energetics of Carbohydrate Interactions in Water.

    1996-10-04

    Thermodynamic studies of the binding of a series of p-nitrophenyl glycosides (PNPGly) of varying stereochemistry to alpha-cyclodextrin (alpha-CD) were performed at three different temperatures (25, 35, and 42 degrees C) using a microcalorimetric technique. The system p-nitrophenol (PNP) at pH = 3 and alpha-CD was also studied for the sake of comparison. All these complexes were found to be enthalpy driven with a favorable enthalpic term clearly dominant over an unfavorable entropic term. A clear enthalpy-entropy compensation effect was observed at all the temperatures, with a slope close to unity (alpha = 1.02) and an intercept TDeltaS degrees (o) = 2.91 kcal mol(-)(1). This thermodynamic pattern is in agreement with those usually found for lectin-carbohydrate associations and for the binding processes of several host-guest systems. This pattern is explained in terms of the contribution of primarily two driving forces: the van der Waals interactions between the host and the guest, and the solvation/desolvation processes which accompany the association reaction. The presence of the carbohydrate molecule in the PNP ring causes a slight destabilization of the complex at 25 degrees C with respect to the alpha-CD-PNP (pH = 3) complex, although a different behavior has been observed depending on the axial/equatorial configuration of the glycoside and the temperature. This behavior is modulated by the stereochemistry of the glycoside. Differences were observed between the deoxy-derivatives (LAra and LFuc) and those derivatives with a hydroxymethyl group (Glc, Gal, Man). DeltaC(p) degrees values were obtained from the dependency of DeltaH degrees on temperature (=( partial differentialDeltaH degrees / partial differentialT)(p)). These values are small and negative except for alphaMan complex. For the latter complex, discrepancy between the calorimetric and the calculated van't Hoff enthalpies was observed. Parallels are drawn between the thermodynamics of our model and

J Strength Cond Res XX(X): 000-000, 2017-To date, it is still unknown why some individuals develop higher levels of muscle damage than other individuals, despite participating in exercise with comparable levels of physical intensity. The aim of this investigation was to analyze 7 single-nucleotide polymorphisms (SNPs) that are candidates to explain individual variations in the level of muscle damage attained during a half-ironman competition. Using the model of Williams and Folland (2, 1, and 0 points for optimal, intermediate, and suboptimal genotype), we determined the total genotype score from the accumulated combination of 7 SNPs (ACE = 287bp Ins/Del; ACTN3 = p.R577X; creatine kinase, muscle type = NcoI; insulin-like growth factor 2 = C13790G; interleukin-6 = 174G>C; myosin light chain kinase = C37885A; and tumor necrosis factor-α = 308G>A) in 22 experienced triathletes. Before and after the race, a sample of venous blood was obtained to measure serum markers of muscle damage. Two groups of triathletes were established according to their postcompetition serum CK concentration: low CK responders (n = 10; 377 ± 86 U·L) vs. high CK responders (n = 12; 709 ± 136 U·L). At the end of the race, low CK responders had lower serum myoglobin concentrations (384 ± 243 vs. 597 ± 293 ng·ml, p = 0.04). Although the groups were similar in age, anthropometric characteristics, and training habits, total genotype score was higher in low CK responders than in high CK responders (7.7 ± 1.1 vs. 5.5 ± 1.1 point, p < 0.01). A favorable polygenic profile can contribute to reducing the level of muscle damage developed during endurance exercise.

  17. Long-Range Attractive and Repulsive Interactions between Colloidal Particles at the Air/Water Interface

    NASA Astrophysics Data System (ADS)

    Gómez-Guzmán, Oscar; Ruiz-García, Jaime

    2001-03-01

    In the last few years there has been evidence of long-range attractive interactions between colloidal particles trapped between glass plates, where the plates separation is a few particle’s diameter.[1,2,3] In these experiments it is believe that the glass walls play an important role for the observed attractions. Colloidal particles trapped at the air water interface show the formation of different 2-D colloidal patterns such as foams, clusters and chains,[4,5,6,7] whose formation can be taken as an evidence of long range attractive interaction. Here, we present measurements of the pair interaction potential between 0.5 µm colloidal particles at the air/water interface. The potential shows an attractive secondary minimum at about 1.9s, where s is the particle’s diameter, and a secondary repulsive maximum at longer distances. Surprisingly, the position of the secondary well is at a position similar to those found on the colloidal systems trapped between glass plates. It is possible that in our colloidal system the interface plays the role of a glass plate. However, we do not have a clear explanation on the origin of the attractive component of the interaction potential. 1. G. M. Kepler and S. Fraden, Phys. Rev. Lett. 73, 356 (1994) 2. M. D.

    Desde la reciente detección de planetas gigantes orbitando estrellas cercanas de tipo solar por medio de efecto Doppler, uno de los principales problemas, en cuanto al estudio de los sistemas planetarios extrasolares, se refiere a la posibilidad de obtener evidencia directa de su existencia. Esto parece ser factible gracias a que en un futuro cercano entrarán en operación algunos telescopios especialmente adecuados a estos propósitos. Por tal motivo, hemos comenzado desde hace un tiempo un esfuerzo en cuanto al estudio de la evolución planetaria. A tales efectos hemos adaptado el código de evolución estelar de nuestro Observatorio al caso planetario. Las principales diferencias entre el caso estelar y el planetario se encuentran en la ecuación de estado. A tales fines hemos incluído la reciente ecuación de estado de Saumon, Chabrier y Van Horn, las opacidades radiativas de Guillot et al., procesos de quema de Deuterio, etc. También se ha considerado la posible existencia de fases de hielo y roca en el interior planetario. Por el momento hemos despreciado los efectos de la rotación planetaria. Con este código hemos computado la evolución de planetas con masas desde 10 hasta 0.3 masas de Júpiter. Utilizando nuestros resultados numéricos discutimos la detectabilidad de estos objetos en condiciones realistas.

    The term persistent vegetative state (PVS) refers to the only circumstance in which an apparent dissociation of both components of consciousness is found, characterized by preservation of wakefulness with an apparent loss of awareness. Several authors have recently demonstrated by functional neuroimaging studies that a small subset of unresponsive "vegetative" patients may show unambiguous signs of consciousness and command following that is inaccessible to clinical examination at the bedside. The term "estado vegetativo" used in Spanish to describe the PVS syndrome by physicians came from the English-Spanish translation. The Spanish term "vegetativo" is related to unconscious vital functions, and "vegetal" is relative to plants. According to our experience, when a physician informs to patients' relatives that his/her family member's diagnosis is a "estado vegetativo", they understand the he/she is no more a human being, that there is no hope of recovery. The European Task Force on Disorders of Consciousness has recently proposed a new term, unresponsive wakefulness syndrome (UWS), to assist society in avoiding the depreciatory term vegetative state. Our group has embraced the use of the new term UWS and might suggest that we change our concept and use of the term MCS to minimally responsive wakefulness state (MRWS), or minimally aware wakefulness state (MAWS). Medical terms must be current and avoid any pejorative description of patients, which will promote our abilities to serve humankind and challenge neuroscientists to offer society new and realistic hopes for neurorehabilitation.

    The 1957/58 Capelinhos eruption on Faial Island in the Azores is well known for being an excellent example of Surtseyan hydromagmatic volcanic activity. Less well known are the responses of the Portuguese authorities to the eruption and subsequent earthquake in May 1958, and the ways in which well-thought-out and generally effective recovery programmes were put in place. At the time Portugal was ruled by a dictatorship, the Estado Novo (New State). Only superficially similar to other fascist governments in Southern Europe, the Estado Novo collected huge amounts of data on the responses of the authorities to the disaster and their programmes of recovery, but never encouraged academic evaluation of policy, although it ensured that the scientific aspects of the eruption and earthquake were meticulously recorded and published. In this paper we remedy this situation by discussing the details of the immediate response to the emergency and the ways in which the island recovered in its aftermath. The study is based not only on archival sources and demographic and economic data, but also on detailed interviews with survivors some of whom were also decision makers. We argue that response, recovery and rehabilitation were generally highly successful and assess the lessons of the 1957/58 emergency which are relevant to future geophysical disasters in Faial and the wider Azores. Since the 1974 revolution Portugal has been a democratic state. We conclude that both the legislation and the civil defence infrastructure, necessary to achieve a similarly strong and successful response, are in place today.

    Liquid hydrocarbons contained in Argentina's Pico Truncade natural gas caused a number of serious pipeline transmission and gas processing problems. Gas del Estado has installed a series of efficient liquid removal devices at the producing fields. A flow chart of the gasoline stripping process is illustrated, as are 2 types of heat exchangers. This process of gasoline stripping (gas condensate recovery) integrates various operations which normally are performed independently: separation of the poor condensate in the gas, stabilization of the same, and incorporation of the light components (products of the stabilization) in the main gas flow.

    We consider three dimensional surface water waves in the potential theory regime. The bottom topography can have a quite general profile. In the case of linear waves the Dirichlet-to-Neumann operator is formulated in a matrix decomposition form. Computational simulations illustrate the performance of the method. Two dimensional periodic bottom variations are considered in both the Bragg resonance regime as well as the rapidly varying (homogenized) regime. In the three-dimensional case we use the Luneburg lens-shaped submerged mound, which promotes the focusing of the underlying rays. FAPERJ Cientistas do Nosso Estado Grant 102917/2011 and ANP/PRH-32.

    Resumen: En este artículo presentamos el proyecto de capacitación llevado a cabo en comunidades de la sierra y costa de Oaxaca, México, desde 1991, por el Centro de Capacitación Integral para Promotores Comunitarios (CECIPROC). La decisión de hacer este trabajo en Oaxaca responde a que ese estado ocupa uno de los primeros lugares de marginación y de desnutrición en menores de 5 años. El objetivo es describir un modelo de capacitación y compartir parte de las experiencias derivadas, tanto del modelo como del trabajo realizado en las distintas áreas (nutrición y alimentación, salud comunitaria, ecología y etnobotánica, y educación y organización), por promotores mujeres y hombres en sus comunidades. La experiencia obtenida en 24 años muestra la factibilidad técnica y social del proyecto en el ámbito de la salud, el reconocimiento social del proyecto del CECIPROC como un organismo civil que ha aportado alternativas como solución a la problemática de salud, el hacer suyo el proyecto por algunos promotores y los diferentes obstáculos a los que se ha enfrentado. Enfatizamos el hecho de que la situación socioeconómica y política prevaleciente en el estado de Oaxaca es una limitante para el buen desarrollo de los programas colectivos de salud, e insistimos en la necesidad de compartir nuestras experiencias para que puedan ser utilizadas en la planificación y ejecución de otros proyectos.

  14. A new genus of pine-feeding Cochylina from the western United States and northern Mexico (Lepidoptera: Tortricidae: Euliini).

    2013-01-01

    Eupinivora, new genus, is described and illustrated from the montane regions of western United States (Nevada, Utah, Wyoming, Colorado, Arizona, New Mexico, and Texas) and Mexico (Nuevo León, Durango, and Estado de Mexico). As presently defined, the genus includes seven species: E. ponderosae, n. sp. (USA: Arizona) (type species); E angulicosta, n. sp. (Mexico: Nuevo León); E. albolineana, n. sp. (Mexico: Durango); E. thaumantias (Razowski, 1994), n. comb. (Mexico: Estado de Mexico); E. hamartopenis (Razowski, 1986), n. comb. (Mexico: Durango); E. unicolora, n. sp. (Mexico: Durango); and E. rufofascia, n. sp. (Mexico: Durango). The new genus is most closely related to Henricus Busck, 1943, from which it can be distinguished by the short upturned labial palpi, the presence of a variable cluster of long spine-like external setae from near the middle of the phallus in the male genitalia, the absence of cornuti in the vesica, the absence of the subgenital sex scales in the male, and a forewing pattern that in most of the included species is reminiscent of that of Argyrotaenia ponera Walsingham and its relatives. Four of the new species were reared from the cones of Pinus arizonica var. cooperi Blanco (Pinaceae) and one from Pinus ponderosa P. & C. Lawson; all of the species occur in habitats dominated by conifers at elevations between ca. 1700 and 2750 m. Two specimens from New Mexico were collected in traps baited with a synthetic pheromone for the bud worm Choristoneura lambertiana (Busck, 1915) (Archipini)-90% 92:8E:Z11-14AC, 10% 90:10E:Z11OH--which is consistent with that recorded for other Cochylina.

    Are there differences in the effectiveness of pelvic floor muscle training on pelvic floor muscle strength and urinary incontinence symptoms in postmenopausal women who are and are not using hormone therapy? Randomised, controlled trial with concealed allocation, blinded assessors, and intention-to-treat analysis. Ninety-nine postmenopausal women, 38 of whom were using daily systemic oestrogen/progestogen therapy. The experimental group (n=51) received an intensive supervised pelvic floor muscle training protocol, and the control group (n=48) received no intervention. The randomisation was stratified by hormone therapy use. Change in pelvic floor muscle strength assessed with manometry at 12 weeks. Prevalence and severity of urinary incontinence symptoms were assessed using questionnaires. Eighty-eight women provided data that could be included in the analysis. Pelvic floor muscle training increased pelvic floor muscle strength by 8.0 cmH 2 O (95% CI 3.4 to 12.6) in women not using hormone therapy and by -0.9 cmH 2 0 (95% CI -6.5 to 4.8) in women using hormone therapy (interaction p=0.018). A sensitivity analysis showed that the greater training effect in women who were not using hormone therapy was still apparent if the analysis was conducted on percentage change in strength rather than absolute change in strength. There was also a significantly greater effect of training in women not using hormone therapy on prevalence of urinary incontinence symptoms (ratio of odds ratios=7.4; interaction p=0.028). The difference in effects on severity of urinary incontinence symptoms was not statistically significant (interaction p=0.37). Pelvic floor muscle training increases pelvic floor muscle strength more in women who are not using hormone therapy than in women using hormone therapy. ClinicalTrials.gov NCT02549729.

  18. Exploring external time-dependent sources of H2O into Titan's atmosphere

    2014-05-01

    Recent observations (Cottini et al., 2012, and Moreno et al., 2012) and steady-state photochemical modelling (Moreno et al., 2012; Dobrijevic et al., 2014) indicate that the amounts of CO2 and H2O in Titan's stratosphere imply relatively inconsistent values of the OH/H2O input flux. Moreno et al. (2012) proposed that the oxygen source is time-variable, whereas Dobrijevic et al. (2014) arrived to the same conclusion of Moreno et al. (2012) that the HSO (Herschel Space Observatory) measured H2O profile is'inconsistent" with the CO2 abundance. Furthermore, Dobrijevic et al. (2014) also found that reconciliation was possible if abundances reported by Cottini et al. (2012) are correct instead, though in this situation and for an Enceladus source, their model tended to overpredict the thermospheric abundance of H2O , compared to the upper limit by Cui et al. (2009). We attempt to reconcile the H2O and CO2 observed profiles in Titan's atmosphere by considering several time-dependent scenarios for the infux/evolution of oxygen species. To explore this, we use a time-dependent photochemical model of Titan's atmosphere to calculate effective lifetimes and the response of Titan's oxygen compounds to changes in the oxygen input flux. We consider a time-variable Enceladus source, as well as the evolution of material delivered by a cometary impact. We will show results on effective H2O and CO2 effective lifetimes, on the feasibility of time-variable Enceladus source, and on an additional H2O loss-to-the-haze. Regarding CO2, we will analyse its production following a cometary impact. A summary on viable scenarios to explain the H2O / CO2 puzzle will be given. References Moreno, R., Lellouch, E., Lara, L.

  19. Dust Production of Comet 21P/Giacobini Zinner Using Broadband Photometry

    NASA Technical Reports Server (NTRS)

    Blaauw, Rhiannon; Suggs, Robert M.; Cooke, William

    2012-01-01

    Comet 21P/Giacobini-Zinner is a Jupiter family comet that was discovered in December of 1900 by the French astronomer Michel Giacobini, and rediscovered two orbits later by German astronomer Ernst Zinner in 1913. 21P is approximately 2 km in diameter, and is the parent of the Draconids, a meteor shower known to undergo dramatic outbursts. In 1933 and 1946, up to 10,000 meteors per hour were reported for the Draconids; and 2011 saw a minor Draconid outburst. As meteor stream modeling/ forecasting is a primary focus for the NASA Meteoroid Environment Office, it was decided to monitor 21P for three purposes: firstly to find the apparent and absolute magnitude with respect to heliocentric distance; second to calculate Af(rho), a quantity that describes the dust production rate and is used in models to predict the activity of the Draconids; thirdly to detect possible increases in cometary activity, which could correspond to future Draconid meteor outbursts. Giacobini-Zinner is unique in several ways. It was the first comet to have measurements made in situ. Comet 21P was visited by ICE (International Cometary Explorer) in 1985 to study the interaction of the cometary atmosphere with the flowing solar-wind plasma. It is a carbon-depleted comet, and most studies show that it peaks in gas and dust production pre-perihelion, specifically in two very studied passages; 1985 and 1998. A prior study was conducted by Pittichova et al (2008) for 21P during its 2004-2006 close approach to the Sun. Apparent and absolute magnitudes were measured at various heliocentric distances as well as the dust production. At 2.32 AU from the Sun, 21P exhibited an apparent magnitude of 17.05 and Af of 83 cm, and an apparent magnitude of 15.91/Af(rho) of 130.66 cm at 1.76 AU. Another such study performed by Lara et al.on 21P s 1998 apparition found values of Af(rho) of 1010 cm when 1.05 AU from the Sun, two weeks before perihelion, and 669 cm at perihelion, when 1.03 AU from the Sun

    Site effects have been recognized to play an important role in damage distribution of destructive earthquakes. These effects have been observed in Venezuela especially during the 1967 Caracas earthquake, when 4 buildings with 10 and more storeys during the Caracas 1967 earthquake collapsed, and a big number of them in the same deep sediment area have been seriously damaged. This motivated the development of studies regarding the subsurface configuration of Caracas and Barquisimeto during the last decade, with a seismic microzoning project realized in both cities from 2005 to 2009. The main results of this project were the development of design response spectra for the different microzones within the sedimentary basin, as well as estimates of landslide hazard. Implementation of the results in municipality ordinances is actually discussed with local authorities. They are aimed to address mitigation for new constructions by the application of the specific design spectra, for existing buildings via evaluation and retrofitting strategies, and for slope areas (informal, as well as formal developments) due to the identification of areas that may not be developed or require detailed studies of slope stabilities. Since then, seismic microzoning studies were started in Cumaná, Guarenas/Guatire and Lara state, and within a broader context of integrated risk management, which includes flooding, landslide and technological risks, in Mérida, Valencia, Maracay, Barcelona/Puerto La Cruz and Valle de la Pascua. The projects are coordinated by the Venezuelan Foundation for Seismological Research (FUNVISIS) in cooperation with local universities. Efforts are done to unable local researchers to apply the methodologies in other cities as Valera, Trujillo, Boconó, San Cristóbal and Tucacas. A unified seismic hazard map as input motion to these studies is actually in development. Depending on the local characteristics, building inventory and vulnerability analysis are done for risk

    In the Western world, the population developed an overweight profile. The morbidly obese generate higher cost to the health system. However, there is a gap in this approach with regard to individuals above the eutrofic pattern, who are not considered as morbidly obese. To correlate nutritional status according to BMI with the costs of laparoscopic cholecystectomy in a public hospital. Data were collected from medical records about: nutritional risk assessment, nutricional state and hospital cost in patients undergoing elective laparoscopic cholecystectomy. Were enrolled 814 procedures. Average age was 39.15 (±12.16) years; 47 subjects (78.3%) were women. The cost was on average R$ 6,167.32 (±1830.85) to 4.06 (±2.76) days of hospitalization; 41 (68.4%) presented some degree of overweight; mean BMI was 28.07 (±5.41) kg/m²; six (10%) individuals presented nutritional risk ≥3. There was a weak correlation (r=0.2) and not significant (p <0.08) between the cost of hospitalization of the sample and length of stay; however, in individuals with normal BMI, the correlation was strong (r=0,57) and significant (p<0.01). Overweight showed no correlation between cost and length of stay. However, overweight individuals had higher cost of hospitalization than those who had no complications, but with no correlation with nutritional status. Compared to those with normal BMI, there was a strong and statistically significant correlation with the cost of hospital stay, stressing that there is normal distribution involving adequate nutritional status and success of the surgical procedure with the consequent impact on the cost of hospitalization.

El objetivo de este documento esta dirigido a revisar el desempeno de las moscas esteriles frente a poblaciones silvestres procedentes de diferentes ambientes y para esto se realizaron comparaciones de compatibilidad y competitividad sexual de las moscas esteriles contra poblaciones silvestres de seis estados representativos de la Republica Mexicana: Nuevo Leon, Tamaulipas, Sinaloa, Nayarit, Michoacan y Chiapas. Los resultados obtenidos manifiestan diferencias en el horario de inicio de llamado y mayor actividad sexual del macho entre las moscas provenientes de cada estado. Sin embargo el indice de aislamiento (ISI) reflejo compatibilidad sexual entre la cepa de laboratorio y todas las poblaciones analizadas, indicando que los individuos esteriles pueden aparearse satisfactoriamente con las poblaciones silvestres de los seis estados. El indice de efectividad de apareamiento del macho (MRPI) reflejo de manera global que los machos esteriles son tan efectivos para copular como los silvestres. El indice de efectividad de apareamiento de la hembra (FRPI) reflejo que en la mayoria de los estados las hembras silvestres copularon en mayor proporcion que las hembras esteriles, excepto para las poblaciones de Tamaulipas y Chiapas. En general, la baja participacion de las hembras esteriles en el campo permitio al macho esteril ampliar su probabilidad de apareamiento con las hembras silvestres. En cuanto al indice de esterilidad relativa (RSI), observamos que la aceptacion de las hembras silvestres al macho esteril (25-55%) fue similar a la de los machos silvestres.

    Sea level is an environmental variable which is widely recognised as being important in many scientific disciplines as a control parameter for coastal dynamical processes or climate processes in the coupled atmosphere-ocean systems, as well as engineering applications. A major source of sea-level data are the national networks of coastal tide gauges, in Spain belonging to different institutions as the Instituto Geográfico Nacional (IGN), Puertos del Estado (PE), Instituto Hidrográfico de la Marina (IHM), etc. The tide gauge of l'Estartit is a traditional floating gauge placed 21 years ago and has an accuracy of ± 2 mm. Since 1996, l'Estartit tide gauge has been co-located with geodetic techniques (GPS measurements of XU, Utilitary Network, and XdA, Levelling Network,) and it is tied to the SPGIC (Integrated Geodetic Positioning System of Catalonia) project of the Cartographic Institute of Catalunya (ICC). In 2006, due to the work for the expansion of the harbour, the tide gauge had to be moved. Before the work started, appropiate GPS measurements were carried out in order to ensure the connection of the tide gauge data. During October 2006 and May 2008, the tide gauge was inactive and it has been moved on to a new location inside the harbour. In June 2008, new GPS and levelling measures have been done in order to tie the new location into SPGIC project and to co-locate old data respect the new one. Although l'Estartit does not have a GPS permanent station, it is possible to build a virtual one from the service "CATNET web" of the ICC. "CATNET web" is a data distribution system of a virtual GPS permanent station via web. From the coordinates where you want to place the virtual station, the time interval and the measurement rate, the system generates a RINEX file under the requested conditions. At Barcelona harbour there is one MIROS radar tide gauge belonging to Puertos del Estado (Spanish Harbours). It is placed at the dock 140 of the ENAGAS Building.The radar

    To assess the effect of a 12-hour shift on mood states and sleepiness at the beginning and end of the shift. Quantitative, cross-sectional and descriptive study.It was conducted with 70 neonatal intensive care unit nurses. The Brunel Mood Scale (BRUMS), Karolinska Sleepiness Scale (KSS), and a socio-demographic profile questionnaire were administered. When the KSS and BRUMS scores were compared at the beginning of the shift associations were found with previous sleep quality (p ≤ 0.01), and quality of life (p ≤ 0.05). Statistical significant effects on BRUMS scores were also associated with previous sleep quality, quality of life, liquid ingestion, healthy diet, marital status, and shift work stress. When the beginning and end of the shift were compared, different KSS scores were seen in the group of all nurses and in the night shift one. Significant vigor and fatigue scores were observed within shift groups. A good night's sleep has positive effects on the individual`s mood states both at the beginning and the end of the shift. The self-perception of a good quality of life also positively influenced KSS and BRUMS scores at the beginning and end of the shift. Proper liquid ingestion led to better KSS and BRUMS scores.

Our original routines for the calculation of Stokes parameters were complemented with new ones used to improve the quality of our results, and to adapt the software to different needs, in particular, to obtain polarimetric variability curves (applied to blazar studies).

     Introducción: obesidad e inactividad física son importantes factores de riesgo para el desarrollo de hipertensión en adultos. No obstante, hay poca evidencia sobre el efecto de estos factores de riesgo en el desarrollo de hipertensión en población infantil. Objetivo: investigar la asociación del estado nutricional, niveles de actividad física y etnicidad con niveles de hipertensión en escolares entre 6 y 13 años de edad. Métodos: un total de 418 escolares de ascendencia étnica europea (n = 311) y mapuche (n = 107) fueron participantes de este estudio transversal. Se midió el peso, talla, índice de masa corporal (IMC) y presión arterial, utilizando protocolos estandarizados. Resultados: no se encontraron diferencias significativas en IMC, estado nutricional y presión arterial entre niños con ascendencia europea y mapuche. No obstante, la prevalencia de prehipertensión (21,3% vs. 11,1%) e hipertensión (28,9% vs. 18,6%) fue significativamente mayor en escolares mapuches en comparación con europeos, respectivamente. Escolares con ascendencia mapuche tienen un mayor riesgo de desarrollar prehipertensión o hipertensión que escolares con ascendencia europea (OR: 1,92 [1,19 a 3,06], p < 0,01). La prevalencia de hipertensión aumenta significativamente en ambos grupos étnicos con el incremento de IMC y bajos niveles de actividad física. Conclusiones: el riesgo de desarrollar prehipertensión o hipertensión es mayor en población infantil ascendiente de mapuches que ascendiente de europeos y este riesgo se ve acentuado con el incremento de obesidad y bajos niveles de actividad física.

    Introducción: dado el incremento del sobrepeso y obesidad infantil, es relevante estudiar no solo las consecuencias metabólicas, sino también aquellas de índole musculoesqueléticas que pueden afectar la funcionalidad motriz, como es el pie plano, en esta población. Objetivo: identificar la asociación entre el estado nutricional y la prevalencia de pie plano en niños y niñas chilenos de 6 a 10 años. Métodos: el z-score del índice de masa corporal (IMC) y el registro y análisis de las huellas plantares según la metodología de Hernández-Corvo fue llevado a cabo en 388 escolares (52,3% niñas). Un test de diferencia para dos proporciones fue utilizado para evaluar las diferencias entre los grupos. Se considera una significancia estadística con p ≤ 0,05. Resultados: la prevalencia del exceso de peso fue de más del 40%. Esta prevalencia fue más alta en las niñas (47,8%) que en los niños (42,7%). La prevalencia de pie plano en todos los niños fue del 17%, presentando valores más elevados el pie derecho (18,3%) que el izquierdo (15,7%). Hay un incremento significativo de la prevalencia de pie plano en los niños obesos en relación con los niños con sobrepeso y normopeso. Conclusión: el estado nutricional está asociado con incrementos en la prevalencia de pie plano en niños. En la población infantil de 6 a 10 años de edad, la obesidad está asociada con la alteración morfológica del pie.

    2017-01-01

    To conduct a data survey on the subject of medical claims involving civil liability in ophthalmology at the São Paulo Court of Appeals. A case law research was carried out on the São Paulo Court of Appeals website searching for the keyword "ophthalmologist" for all years until 2016. Of the 65 cases found, 29 were selected. There has been an increase in the number of claims in ophthalmology, especially in surgical procedures on the anterior chamber of the eye. Most lower court judgments were for defendant. The study suggested the need for specialists to exercise the required amount of care when treating the patients, so that they may understand the risks inherent to the procedure. Despite the increase in claims, most decisions were favorable for the physician. Realizar um levantamento de dados sobre a temática dos processos envolvendo responsabilidade civil em sede da Oftalmologia no Tribunal de Justiça do Estado de São Paulo. Foi realizada uma pesquisa jurisprudencial por palavra-chave no site do Tribunal de Justiça do Estado de São Paulo com o seguinte termo de pesquisa "oftalmologista" para todos os anos até 2016. Foram encontrados 65 processos, dos quais 29 foram selecionados. Observou-se tendência ao aumento de processos na área, e predominância de processos em procedimentos oftalmológicos cirúrgicos em câmara anterior do olho. A maioria das sentenças de primeira instância foi improcedente. O estudo aponta para a necessidade de atenção dos especialistas para com o paciente, no sentido de que ele compreenda os riscos inerentes ao procedimento. Apesar do aumento de processos, a maioria permanece favorável ao médico.

    Objetivo: analizar la geografía del estado nutricional en España y su evolución entre mediados del siglo xixy comienzos del siglo xx, etapa previa a la transición nutricional con alta prevalencia de malnutrición.Métodos: se utilizan datos antropométricos agregados (promedios provinciales de estatura) del reclutamiento militar en 1858 y 1913, así como promedios provinciales de estatura y peso procedentes de una revisión realizada entre 119.571 soldados en 1903-1906. Con estos datos se elaboran cartografía y estadísticos descriptivos.Resultados: los parámetros antropométricos de los españoles se situaban entre los valores de complexión más bajos de Europa antes de la transición nutricional. Entre 1858 y 1913, la altura media creció solo 1,43 cm. En ese periodo hubo cambios significativos en la geografía antropométrica marcados por la configuración de una polaridad nutricional a las puertas de la I Guerra Mundial: las provincias del centro y del sur de país exhiben mayor incidencia de la malnutrición crónica que las provincias del arco Noreste, que disfrutan de ventaja relativa en términos nutricionales.Conclusión:las desigualdades territoriales que configuraron una geografía polarizada del estado nutricional en España pueden asociarse en parte a los cambios ambientales del periodo, caracterizados por el inicio de la modernización y la industrialización y, asimismo, por la privación derivada de las crisis agrarias, las enfermedades y el relativo atraso tecnológico. Se destaca la relevancia de la historia antropométrica para el estudio de los niveles de vida en poblaciones del pasado y del proceso de transición nutricional.

    A Supreme Decree emitted by the government of Bolivia instituted the celebration of the June solstices in view of the fact that the indigenous people, both the Andean highlands and the Amazon and Chaco, "have commemorated this event for thousands of years" (Gobierno del Estado Plurinacional de Bolivia, Decreto Supremo N° 0173, June16, 2009, La Paz). In the case of the lowlands' indigenous, particularly the Guarani people, the decree mentions the planet Venus as the argument for this celebration. In this case of study and in light of astronomical and ethnographic evidence, we analyze the relevance of this decree in the case of the Guarani people of the Bolivian Chaco region, known as "Chiriguanos".

    To identify the socioeconomic, demographic, operational, and health service-related factors associated with the occurrence of leprosy in a hyperendemic State in North Brazil. This is an ecological study based on secondary data from the Sistema de Informações de Agravos de Notificação in municipalities of the State of Tocantins from 2001 to 2012. Units of analysis were the 139 municipalities of the State. Negative binomial log linear regression models were used to estimate incidence rate ratios. In bivariate analysis, the incidence rate ratios were significantly higher for municipalities with higher income ratio of the poorest 20.0% (1.47; 95%CI 1.19-1.81) and better Municipal Human Development Index (1.53; 95%CI 1.14-2.06). In multivariate analysis, the incidence rate ratios were significantly higher in municipalities with higher proportion of immigrants (1.31; 95%CI 1.11-1.55) and higher proportion of households with waste collection (1.37; 95%CI 1.11-1.69). There was a significant reduction in the incidence rate ratio with increased coverage of the Bolsa Família Program (0.98; 95%CI 0.96-0.99). Control programs need to focus on activities in municipalities of greater social vulnerability with intersectoral investment for the improvement of the living conditions of the population.

    Redbacks belong to the family of binary systems in which one of the components is a pulsar. Recent observations show redbacks that have switched their state from pulsar - low mass companion (where the accretion of material over the pulsar has ceased) to low mass X-ray binary system (where emission is produced by the mass accretion on the pulsar), or inversely. The irradiation effect included in our models leads to cyclic mass transfer episodes, which allow close binary systems to switch between one state to other. We apply our results to the case of PSR J1723-2837, and discuss the need to include new ingredients in our code of binary evolution to describe the observed state transitions.

John Bush (MIT) and coworkers also produced laboratory experiments which were compared to theoretical predictions. Both groups discussed the pilot-wave properties previously thought to be peculiar to the microscopic, quantum realm. Of particular interest is the wavelike statistics for pilot-wave dynamics in a confined domain. We present a one dimensional water wave model for a droplet bouncing in a confined domain. The mathematical model makes use of conformal mapping which allows for the presence of submerged barriers. The computational simulations produce tunneling events.

    to estimate the prevalence of hypoalbuminemia in hospitalized elders, related to socio-demographic variables, nutritional status and length of stay. crosscutting study with 200 patients hospitalized in a large hospital in the South of Brazil during three months. Evaluations, lab tests and interviews through questionnaires were performed. the average albuminemia was 2,9 ± 0,5g/dL. Hypoalbuminemia was diagnosed in 173 subjects (87%) and was absent in 27 (13%) that have normal albuminemia (p=0,000). After six days of hospitalization, the prevalence of low levels grew significantly to 90% (p=0,002), average 2,7 ± 0,5g/dL. Using the Mini Nutritional Assessment, it was observed that 41 patients were malnourished and from those, 40 had hypoalbuminemia. the prevalence of hypoalbuminemia proved to be high, in approx. nine in ten elders, and the nutritional status and the length of stay proved to be related to the decrease of serum albumin levels. Thus, it is suggested that monitoring albumin levels should be done to evaluate the risk that the patient has to develop malnutrition and other complications during hospital stays. estimar a prevalência de hipoalbuminemia em idosos hospitalizados, em relação às variáveis sociodemográficas, estado nutricional e tempo de internação. estudo transversal, com 200 pacientes internados em hospital de grande porte do sul do Brasil, durante o período de três meses.

    Colistin has long been a reserve drug used for the treatment of carbapenem resistant Klebsiella pneumoniae. Carbapenem resistance in K. pneumoniae has been increasing and is as high as 44% in India. Although a reserve agent, with rise in rates of resistance to carbapenems, the usage of colistin has increased over the years leading to slow emergence of resistance. Colistin resistance is mainly mediated by the alteration in the LPS of bacterial outer membrane with the addition of L-Ara4-N and PEtN molecules. These alterations are mediated by mutations in several genes involved in lipidA modifications and most commonly mutations in mgrB gene has been reported. Recently there is emergence of plasmid mediated resistance due to mcr-1 and mcr-2 genes which poses a threat for the rapid global spread. This study aims at characterizing eight colistin resistant K. pneumoniae from bacteremia by whole genome sequencing. Eight K. pneumoniae were isolated from blood culture during 2013 and 2014 at the Department of Clinical Microbiology, Christian Medical College, India. Antimicrobial susceptibility testing was performed and minimum inhibitory concentration (MIC) was determined for colistin and polymyxin B by broth-micro dilution method. Whole genome sequencing was performed using Ion Torrent and the genome of all eight isolates was analyzed. The eight isolates were resistant to all the antimicrobials expect tigecycline. MIC of colistin and polymyxin B were ranged from 4 to 1024 μg/ml and 0.5 to 2048 μg/ml respectively. Multiple mutations were observed in the chromosomal genes involved in lipid A modifications. mcr-1 and mcr-2 gene was absent in all the isolates. The most significant were mutations in mgrB gene. Among the eight isolates, four, three and one were belonged to sequence types ST 231, ST14 and ST147 respectively. Seven isolates had blaOXA−48 like, one co-expressed blaNDM−1 and blaOXA−48 like genes leading to carbapenem resistance. Overall, multiple numbers of

    Khat is a green leaf with amphetamine-like effects. It is primarily used among people in Africa, the Middle East and in the diaspora communities from these countries. Prior to the prohibition of khat in the UK on 24 June 2014, there was almost no information available on key aspects of the local khat market. A cross-sectional study was conducted in 2012 using snowball sampling, Privileged Access Interviewing and area mapping in order to identify khat sale establishments. Data was collected via face-to-face interviews using mixed methods for data collection. This included information about the establishments selling khat, khat pricing and its use among different ethnic minority groups, in addition to the potential sale of khat to children and risk assessment (e.g., use of pesticides on khat). Five out of seven sellers identified agreed to participate. Sellers described their khat sale establishments as 'community centres' which included, for example, a restaurant basement. The sellers' history of selling khat ranged between 1-15 years and khat's sale took place between 2pm-10pm. Miraa (e.g., Lara) from Kenya was the most popularly used khat variety, sold in pre-wrapped bundles of approximately 250 g costing £3 each and delivered four days a week. Harari (e.g., Owdi) from Ethiopia was sold in 200 g, 400 g and 1 kg bundles, priced between £5 and £20 and delivered two days a week. The primary benefit of khat use was reported to be social interaction. The customers were predominantly adult males of Somali origin. Most sellers claimed a self-imposed ban on sales to children under 18 years old. Khat bundles had no labelling describing variety or weight and sellers had no knowledge of the use of pesticides on khat and did not advertise the risks associated with khat use. Khat selling establishments were businesses that did not adhere to trade standards regulations (e.g., labelling khat bundles). They claimed to provide a community service (facilitating social

    Introducción: la desnutrición intrahospitalaria se ha descrito hace más de 70 años como un problema frecuente. En México se reportan cifras de entre el 20% al 50%; sin embargo no se ha estudiado su prevalencia ni su asociación con la morbilidad y mortalidad hospitalaria.Objetivos: evaluar el estado nutricional y su relación con la morbimortalidad hospitalaria en pacientes mexicanos.Métodos: cohorte prospectiva de pacientes que ingresaron en un hospital de referencia para una estancia hospitalaria mayor de 5 días. Se capturó peso, talla, índice de masa corporal (IMC), estado nutricional de acuerdo con la valoración global subjetiva (VGS) a su ingreso y egreso hospitalario, así como diagnóstico médico, complicaciones y mortalidad. Los datos fueron analizados mediante la prueba T de Student, prueba Chi-cuadrado y prueba Exacta de Fisher.Resultados: se incluyeron 610 pacientes en total, con un promedio de edad de 50,8 ± 17,32 años, 267 mujeres (43,8%) y 343 hombres (56,2%). Del total, 154 fueron catalogados con sospecha de desnutrición o desnutrición (pacientes expuestos, 25,2%) y 456 bien nutridos (pacientes no expuestos, 74,8%), con una relación de 1 a 3. La morbilidad total de la cohorte tuvo un RR = 2,70, IC 95 % (2,06-3,55) y la mortalidad con un RR = 2,64, IC 95% (1,74-4,0), siendo ambas estadísticamente significativas (p = 0,001).Conclusiones: el diagnóstico de desnutrición al ingreso hospitalario constituye un factor de riesgo para el desarrollo de complicaciones y mortalidad. Este padecimiento al ingreso en comparación con el paciente que no presenta desnutrición incrementó el riesgo de mortalidad hasta en 2.64 veces.

    A description of the Eastern North Atlantic tidal dynamics (in a region spanning from 20°N to 48°N in latitude and from 34°W to 0° in longitude) is obtained by means of new in situ measurements and numerical modelling based on TOPEX/POSEIDON-derived data sets. The main source of measurements is the tide gauge network REDMAR (RED de MAReógrafos de Puertos del Estado), operative since July 1992 and managed by Clima Marítimo (Puertos del Estado). Results derived from the harmonic analysis of the first years of measurements are presented and compared with model results. In order to obtain a global picture of the tides in the region, a large compilation of harmonic constants obtained from other institutes is included. The availability of new TOPEX/POSEIDON-derived harmonic constants data sets provides a chance to include the benefits derived from satellite altimetry in high resolution regional applications of numerical models. Richard Ray's tidal model (Ray et al., 1994), based on a response type tidal analysis of TOPEX/POSEIDON data, was employed within a model of the studied area. The numerical model employed is HAMSOM, a 3-D finite difference code developed both by the Institut für Meereskunde (Hamburg University) and Clima Marítimo. Results from simulations of seven major harmonics are presented, providing a comprehensive view of tidal dynamics, including current information. The results of tidal simulations show good agreement between semidiurnal harmonic components and the values measured by both coastal and pelagic tidal gauges and by current meters. The modelled diurnal constituents show larger relative differences with measurements than semidiurnal harmonics, especially concerning the phase lags. The non-linear transfer of energy from semidiurnal to higher order harmonics, such as M 4 and M 6, was mapped. Those transfers were found to be important only in two areas: the French continental shelf in the Bay of Biscay and the widest part of the African

    To analyze the association between childhood sexual abuse (CSA) and disordered eating (DE). A probabilistic sample of 2,358 female high school students of public schools in the Estado de Mexico was used. DE was more prevalent among CSA sufferers (p < or = 0.05). Preoccupation with gaining weight, binging and restrictive behaviors were associated to CSA (p < or = 0.05). The probability of DE was 7 times higher when the CSA experience had not been revealed and 36 times when CSA happened before 14 years of age. The association between CSA and DE is clear in the sample studied, as well as with some of its specific characteristics, which highlights the need to deepen in this research field and to incorporate the evaluation of CSA and its consequences in adolescents' mental health.

    This historical-social study aimed to understand the roots of the preinstitutionalization of Professional nursing in a given organizational field. We considered the origins of nursing in the political-social context of the First Republic, Second Republic, beginning of the Estado Novo and the interwar period. The study rests on institutional theory and Bourdieu's notion of field. As an institutional environment, the Hospital do Centenário was a demarcation point for the future organizational field of professional nursing. In the period from 1922 to 1938, an emerging organizational field was evidenced, in which the presence of Public Health and the State stand out. Public Health Visitants and Sanitary Educators appear as the forerunners for the professional bases of nursing. We observed the fight of agents involved in the formation of this field, creating and developing alliances and strategies.

    Chynoweth, E.

    Buyers are lining up for Argentina's two big state-controlled petrochemical groups, Buenos Aires-based Petroquimica General Mosconi (PGM) and Petroquimica Bahia Blance (PBB). However, feedstock supply contracts with government-owned oil group Yacientos Petroliferos Fiscales (YPG) and gas group Gas del Estado hold the key to both sales. Shell Compania Argentina Petroleo SA (CAPSA), Perez Companc, and Global Petroleum have already bought PGM tender documentation.

    Kawasaki disease (KD) is an etiological illness that is relatively unknown and scarcely identified in Mexico; it affects children mainly aged 1-4 years, evolves with fever, vasculitis in diverse organs, and in the heart the disease mainly affects the coronary arteries. Our aim was to inform the clinical findings and evolution of 20 patients diagnosed with KD. We reviewed the patient clinical files retrospectively and descriptively to obtain information with regard to age, sex, clinical signs, laboratory and consultory results, echocardiography findings, complications, evolution during hospitalization, followup, and out-patient ambulatory consultations. Eighteen patients were male, two were female, six developed coronary damage, two aortic mitral-valve insufficiency, one pericardial shedding, and one, myocarditis. All patients received gamma globulin treatment with aspirin, and 16 were controlled during 6-8 months after the acute medical profile.

    Between may and july 2001, a survey was conducted in order to investigate the prevalence and symptoms of Enterobius vermicularis infection and its relationship with the socio-economic status and household crowding of 154 schoolchildren aged 6-12 years from a rural village in Falcon State, Venezuela. The Graham technique (perianal swabs with an adhesive cellulose tape) was used to perform the parasitological diagnosis. The overall prevalence was high (57.79%). There was no difference in the prevalence between sexes (X2 = 0.005; d.f. = 1) or ages (X2 = 3.63; d.f. = 6) (p > 0.05), suggesting similar risk conditions for all individuals. Anal pruritus was the most common clinical finding (53.9%). Other less frequent manifestations were the following: perianal lesions (34.8%) and vulvovaginitis (32.6%). Graffar analysis revealed that the majority of schoolchildren belong to the poorer socioeconomic strata: IV (55.9%) and V (29.87%), with overcrowded living conditions. The correlation between E. vermicularis infection and crowding rates was found to be statistically significant (r = 0.98; p < 0.001). In the light on these results, it can be concluded that poverty, overcrowding, anal pruritus, scarcity of water, inadequate personal and community hygiene play a relevant role on the transmission dynamics and endemic maintenance of enterobiasis among schoolchildren from Sabaneta.

  1. Predicting the ocurrence probability of freak waves baed on buoy data and non-stationary extreme value models

    In the last decades, freak or rogue waves have become an important topic in engineering and science. Forecasting the occurrence probability of freak waves is a challenge for oceanographers, engineers, physicists and statisticians. There are several mechanisms responsible for the formation of freak waves, and different theoretical formulations (primarily based on numerical models with simplifying assumption) have been proposed to predict the occurrence probability of freak wave in a sea state as a function of N (number of individual waves) and kurtosis (k). On the other hand, different attempts to parameterize k as a function of spectral parameters such as the Benjamin-Feir Index (BFI) and the directional spreading (Mori et al., 2011) have been proposed. The objective of this work is twofold: (1) develop a statistical model to describe the uncertainty of maxima individual wave height, Hmax, considering N and k as covariates; (2) obtain a predictive formulation to estimate k as a function of aggregated sea state spectral parameters. For both purposes, we use free surface measurements (more than 300,000 20-minutes sea states) from the Spanish deep water buoy network (Puertos del Estado, Spanish Ministry of Public Works). Non-stationary extreme value models are nowadays widely used to analyze the time-dependent or directional-dependent behavior of extreme values of geophysical variables such as significant wave height (Izaguirre et al., 2010). In this work, a Generalized Extreme Value (GEV) statistical model for the dimensionless maximum wave height (x=Hmax/Hs) in every sea state is used to assess the probability of freak waves. We allow the location, scale and shape parameters of the GEV distribution to vary as a function of k and N. The kurtosis-dependency is parameterized using third-order polynomials and the model is fitted using standard log-likelihood theory, obtaining a very good behavior to predict the occurrence probability of freak waves (x>2).

    Puerto Rico's divide bifurcates in the west into a southern higher-elevation divide and a lower-elevation northern divide. The southern divide trends along exposures of weak, low density serpentinized ocean basement of the Monte de Estado Range forming the highest elevations in western Puerto Rico. Evidence of long-term active uplift along the serpentinite-cored divide is abundant. Streams draining Monte de Estado (MdE) radiate outward from an ellipse centered on the serpentinite exposure. The Rio Anasco draining the north flank of MdE is highly asymmetric, displaying a large scale tilt to the north while the Rio Guanajibo draining its south flank is highly asymmetric with tilt to the south. Subbasins of these rivers are asymmetric, tilted away from the core of the serpentinite exposures. Hypsometric integrals of the Anasco and Guanajibo basins are higher than basins of central and eastern Puerto Rico indicating an inequilibrium condition. The concurrence of morphologic indicators of active uplift (stream patterns and basin asymmetry and hypsometry) with the distribution of topographically elevated low-density serpentinite exposures indicates that MdE is experiencing active diapiric uplift. Northwestern Puerto Rico differs morphologically from the rest of the island. Underlain by island arc crust with exposed igneous and sedimentary strata similar to that of the eastern two-thirds of the island, the Atlantic shore has sea cliffs at the base of a coastal plateau west of the Rio Manati. Rivers draining western Puerto Rico have strikingly lower ratio to valley floor widths to valley height than the rivers to the east indicating incision in response to uplift is greater to the west. Western-most rivers have closer outlet spacing, lower distances from outlets to divide and their watershed have higher hypsometric intergrals all indicating that northwest Puerto Rico is actively uplifting at a rate greater than the eastern two-thirds of the island.

    A razão para o desenvolvimento deste trabalho baseia-se no fato de que muitos professores da Educação Básica (EB) não lidam com conceitos relacionados à astronomia, e quando o fazem eles simplesmente seguem livros didáticos que podem conter erros conceituais. Como é de conhecimento geral a astronomia é um dos conteúdos a serem ensinados na EB fazendo parte dos Parâmetros Curriculares Nacionais e das Propostas Curriculares do Estado de São Paulo, mas é um fato, que vários pesquisadores apontam, a existência de muitos problemas no ensino da astronomia. Com o propósito de minimizar algumas dessas deficiências foi realizado um trabalho de pesquisa com a utilização de questionários pré e pós pesquisa, para tanto foi desenvolvido um Curso de Extensão Universitária para professores da Diretoria de Ensino Regional (DE) que abrange Mauá, Ribeirão Pires e Rio Grande da Serra (no Estado de São Paulo) com os seguintes objetivos: levantar concepções alternativas; subsidiar os professores por meio de palestras, debates e workshops, e verificar o sucesso da aprendizagem após o curso, adotando-se como referência, para a análise dos resultados, os dicionários de Língua Portuguesa (FERREIRA, 2004) e Enciclopédico de Astronomia e Astronáutica (MOURĀO, 1995). Portanto, dezesseis questões foram aplicadas antes e após o curso, assim pode-se verificar após a pesquisa que 100,0% dos professores sabiam os nomes das fases da Lua, 97,0% entenderam que o Sistema Solar é composto por oito planetas, 78,1% foram capazes de explicar como ocorre um eclipse lunar, um eclipse solar e um solstício, 72,7% sabiam como explicar a ocorrência das estações do ano; 64,5% explicaram corretamente a ocorrência do equinócio, 89,7% foram capazes de definir adequadamente o termo cometa; 63,6% definiram asteróide, 54,5% meteoro, 58,1% galáxia, e 42,4% planeta. Os resultados obtidos indicam uma aprendizagem significativa por parte dos participantes.

    The presentation is directed to the description of the actual situation and relevant information of the geodetic infrastructure of Ibiza and Barcelona sites for sea level determination and contribution to regional sea level rise. Time series are being analysed for mean sea level variations www.puertos.es. .In the framework of a Spanish Space Project, the instrumentation of sea level measurements has been improved by providing the Barcelona site with a radar tide gauge Datamar 2000C from Geonica s.l. near an acoustic tide gauge. Puertos del Estado installed in 2007 a MIROS radar tide gauge and the Barcelona Harbour Authority a GPS referente station in the roof of the new Control Tower situated in the Energy Pier. The radar sensor is over the water surface, on a L-shaped structure which elevates it a few meters above the quay shelf. 1-min data are transmitted to the ENAGAS Control Center by cable and then sent each 1 min to Puertos del Estado by e-mail. There is a GPS station Leica Geosystems GRX1200 GG Pro and antenna 1202. Precision levelling has been made several times in the last two years because the tower is founded in reclaimed land. The measured settlement rate is about 1cm/year that may be could mask the values registered by the tide gauge. A description of the actual infrastructure at Ibiza harbour at Marina de Botafoch, is presented and its applications to sea level monitoring and altimeter calibration in support of the main CGPS at Ibiza harbour. It is described the geometrical precision levelling made in June 2013 between the radar tide gauge and the GPS station. In particular, the CGPS located at Ibiza harbour is essential for its application to the marine campaign Baleares 2013, near Ibiza island. The main objective is to determine the altimeter bias for Jason-2, about 9:09 UTC September 15, 2013, and Saral/AltiKa, about 05:30 UTC September 16, UTC. These activities has been received funding of the Ministerio de Ciencia e Innovacion under Spanish

    Soil surface characteristics are subjected to changes driven by several interactions between water, air, biotic and abiotic components. One of the examples of such interactions is provided through biological soil crusts (BSC) in arid and semi-arid environments. BSC are communities composed of cyanobacteria, fungi, mosses, lichens, algae and liverworts covering the soil surface and play an important role in ecosystem functioning. The characteristics and formation of these BSC influence the soil hydrological balance, control the mass of eroded sediment, increase stability of soil surface, and influence plant productivity through the modification of nitrogen and carbon cycle. The site of this work is located at Quibor and Ojo de Agua (Lara state, Venezuela). The Quibor Depression in Venezuela is a major agricultural area being at semi-arid conditions and limited drainage favor the natural process of salinization. Additionally, the extension and intensification of agriculture has led to over-exploitation of groundwater in the past 30 years (Méndoza et al., 2013). The soil microbial crust develops initially on physical crusts which are mainly generated since wetting and drying, being a recurrent feature in the Quíbor arid zone. The microbiotic crust is organic, composed of macro organisms (bryophytes and lichens) and microorganisms (cyanobacteria, fungi algae, etc.); growing on the ground, forming a thickness no greater than 3 mm. For further details see Toledo and Florentino (2009). This study focus on characterize the development stage of the BSC based on image analysis. To this end, grayscale images of different types of biological soil crust at different stages where taken, each image corresponding to an area of 12.96 cm2 with a resolution of 1024x1024 pixels (Ospina et al., 2015). For each image lacunarity and fractal dimension through the differential box counting method were calculated. These were made with the software ImageJ/Fraclac (Karperien, 2013

    Italian Law 81/08 (so-called "Unified Text of Laws on Health and Safety at Work"), came into force on 15 May 2008 and incorporates provisions related to medical surveillance of drug and alcohol dependency at the workplace. Occupational health traditionally addresses the issue of protection of worker from occupational hazards. The issue of protection of third parties from behaviour of workers resulting from drug and alcohol dependency implies an original methodological approach, involving full cooperation of employer, employees, and health and safety consultants. A consensus development meeting was organized under the leadership of the Italian Study Group on Hazardous Workers (La.R.A. group). The meeting brought together physicians of different specialties, legal experts and bioethicists, labour and management policy-makers, to discuss the issue and define the research data available, the standards that were appropriate, and which policies were fair. The efficacy of medical surveillance, including workplace drug-testing, relies on a comprehensive policy, including written and verbal information on the use of alcohol and drugs on the job, training for supervisors and management, employee education, and employee assistance structures. Sample collection and testing should be carried out in accordance with standardized and tested procedures. Small businesses will need assistance, including development of model policies, setting up consortia for testing services and if necessary request for National Insurance benefits to reduce costs. The recently introduced Italian legislation on occupational safety and health closely resembles Finnish law since it consists of a "double channel" for workplace drug testing. At recruitment, the employer is entitled to ask a job applicant for a certificate of "Job fitness", including drug tests, that can be issued only by a public health institution, where the job applicant works on a well-defined set of tasks which require accuracy

Les résultats se sont révélés semblables à ceux des études antérieures réalisées aux États-Unis; les groupes ont fait des choix plus compétitifs que les individus. En outre, ni la magnitude de l'effet de discontinuité, ni la fréquence des choix compétitifs faits par les groupes n'étaient plus grands chez les Japonais comparativement à la majorité des études antérieures menées aux États-Unis. Ces résultats soutiennent la robustesse interculturelle de l'effet de discontinuité entre les individus et entre les groupes. Aussi, fait intéressant, ils contredisent la simple distinction entre l'individualisme et le collectivisme. Les implications pour des études sur les cultures et les processus de groupe sont discutées. El efecto de discontinuidad entre individuos y entre grupos es la tendencia a que las relaciones entre grupos sean más competitivas que las relaciones entre individuos.

    Conventional viscous fingering flow in radial Hele-Shaw cells employs a constant injection rate, resulting in the emergence of branched interfacial shapes. The search for mechanisms to prevent the development of these bifurcated morphologies is relevant to a number of areas in science and technology. A challenging problem is how best to choose the pumping rate in order to restrain growth of interfacial amplitudes. We use an analytical variational scheme to look for the precise functional form of such an optimal flow rate. We find it increases linearly with time in a specific manner so that interface disturbances are minimized. Experiments and nonlinear numerical simulations support the effectiveness of this particularly simple, but not at all obvious, pattern controlling process.

    Yeast strains capable of direct fermentation of manioc starch were developed by hybridizing strains of Saccharomyces diastaticus and Saccharomyces cerevisiae. Hybrids were evaluated for speed of alcohol production, and yields and speed of formation of glycoamylase. Up to 6% solutions of Lintner starch could be fermented directly with about 80% conversion to alcohol. Pretreatment of crude 40% manioc starch suspensions with alpha-amylase, followed by fermentations with a starch-fermenting yeast strain, permitted accumulation of 12% ethanol within three days. Starch conversion was almost 100%. A fragment of DNA was cloned from S. diastaticus using the yeast-E. coli shuttle vector, YEp13, andmore » was used to transform a strain of S. cerevisiae to a starch-fermenting state. Supported by National Science Foundation grant INT 7927328 and National Institutes of Health grant GM 27860.

    El estudio clínico del estado nutritivo de un grupo de niños en edad escolar, habitantes de un suburbio madrileño revela la existencia, relativamente rara, de signos carenciales específicos, que contrasta vivamente con el considerable retraso que se observa en su desarrollo somático. Los hechos parecen demostrar que el problema nutritivo de estos niños es sobre todo un problema cuantitativo. El retraso de la evolución está en relación con la insuficiencia global de la dieta y con el déficit de calcio que es probablemente el elemento individual con mayor grado de carencia en las dietas. La anemia que presenta el 98% de los niños no parece deberse únicamente a una deficiencia de hierro porque la dieta parece tener una cantidad adecuada; probablemente esté más en relación con el exiguo contenido de proteínas animales de la ración.

    Nowhere in Latin America has the privatization process been more aggressively pursued than in Argentina where President Carlos Menem has successfully turned over the bulk of state companies to the private sector. In the energy sector, that meant the divestiture in 1992 of Gas del Estado, the state-owned integrated gas transportation and distribution company. It was split in two transportation companies: Transportadora de Gas del Sur (TGS) and Transportadora de Gas del Norte (TGN), and eight distribution companies. TGS is the largest transporter of natural gas in Argentina, delivering more than 60 percent of that nation`s total gas consumption withmore » a capacity of 1.9 Bcf/d. This is the second in a series of Pipeline and Gas Journal special reports that discuss the evolving strategies of the natural gas industry as it continues to restructure amid deregulation.

Simultanément, un effort coordonné en vue de l'achèvement de l'enregistrement des usagers de l'eau a été fait avec l'autorité fédérale, en même temps que d'autres mesures de soutien, telles que des programmes de formation et des campagnes de surveillance. Cet article présente une vue d'ensemble des réalisations de projets et des défis. Resumen El Estado de Guanajuato, situado en el centro de México, ocupa menos del 2% de la superficie del país. Tiene casi 17.000 pozos profundos, de los cuales se extrae cerca de 4.000 hm3/a, lo que supone un exceso de 1.000 hm3/a respecto a la recarga anual. Puesto que el agua es administrada a nivel federal en México, el gobierno del Estado afronta el reto de asegurar el desarrollo de la población sin disponer de medios formales de intervención. Dadas las limitaciones para aplicar políticas y medidas reguladoras, el programa del agua en el Estado tiene como objetivo principal la implantación de una doble estrategia. Por un lado, desarrollar estudios hidrogeológicos básicos y modelos matemáticos de flujo y transporte de los acuíferos, basándose en una campaña exhaustiva de pozos existentes y en una revisión del marco geológico del Estado. Por otro lado, promover-con soporte financiero, técnico y político-una estructura de participación de los usuarios en las acciones de gesti

    The determination of global and regional mean sea level variations with accura-cies better than 1 mm/yr is a critical problem, the resolution of which is central to the current debate on climate change and its impact on the environment. Highly accurate time series from both satellite altimetry and tide gauges are needed. Measuring the sea surface height with in-situ tide gauges and GPS receivers pro-vides an efficient way to control the long term stability of the radar altimeters and other applications as the vertical land motion and studies of sea level change. L’Estartit tide gauge is a classical floating tide gauge set up in l’Estartit harbour (NE Spain) in 1990. Data are taken in graphics registers from which each two hours the mean value is recorded in an electronic support and delivered to the Permanent Service for Mean Sea level (PSMSL). Periodic surveying campaigns along the year are carried out for monitoring possible vertical movement of the geodetic benchmark adjacent to the tide gauge. Puertos del Estado (Spanish Harbours) installed the tide gauge station at Ibiza har-bour in January 2003 and a near GPS reference station. The station belongs to the REDMAR network, composed at this moment by 21 stations distributed along the whole Spanish waters, including also the Canary islands (http://www.puertos.es). The tide gauge also belongs to the ESEAS (European Sea Level) network. A description of the actual infrastructure at Ibiza, Barcelona and l’Estartit har-bours is presented.The main objective is the implementation of these harbours as a precise geodetic areas for sea level monitoring and altimeter calibration. Actually is a CGPS with a radar tide gauge from Puertos del Estado and a GPS belonging to Puerto de Barcelona. A precise levelling has been made by the Cartographic Insti-tute of Catalonia, ICC.

    Introducción: a escala mundial y nacional se reporta una alta prevalencia de sobrepeso y obesidad en menores de 5 años. La etiología es multifactorial, pero factores ambientales como sedentarismo y el progresivo deterioro de la alimentación promueven el exceso de peso y conllevan a mayor riesgo de enfermedades crónicas no transmisibles en temprana edad.Objetivo: describir la ingesta de alimentos, energía y nutrientes en los niños de 2-4 años con obesidad y eutróficos del programa "Buen Comienzo".Método: estudio de corte con 111 niños con obesidad clasificada según IMC >3 DE, que fueron pareados por sexo, edad y tipo de atención con un niño clasificado con estado nutricional normal. Personal entrenado realizó la valoración antropométrica con equipos y métodos estandarizados y se evaluó la ingesta dietética a través de recordatorio de 24 horas. Se aplicó la prueba t-student y U de Mann Whitney en el análisis bivariado y para determinar el patrón de consumo de alimentos y se efectuó un análisis de clases latentes (ACL).Resultados: los niños tienen un consumo de energía superior a su requerimiento, pero existe diferencia significativa según el estado nutricional; el consumo en los niños obesos es de 1.632 kcal (IQR: 1.475-1.801 kcal) y eutróficos de 1.798 kcal (IQR 1.702-1.632 kcal) (p = 0,00). Los niños con peso adecuado tienen mayor ingesta de macronutrientes y micronutrientes (p < 0,05); hay una mayor ingesta de proteínas y micronutrientes durante la semana (p < 0,05); el 30% de los niños no consumió ninguna verdura y el 60% ninguna fruta el día anterior a la encuesta y tuvieron, además, un alto consumo de azúcares y dulces.Conclusiones: los niños están sometidos a una dieta obesogénica caracterizada por un bajo consumo de frutas y verduras y una alta ingesta de energía, grasas saturadas y carbohidratos concentrados, lo que promueve una ganancia de peso no deseado.

Como muestra de la caracterización de los procesos fotofísicos y fotoquímicos en fotobiología teórica, hemos elegido la descripción de la conversión interna ultrarrápida que tiene lugar en los cromóforos del ADN. Los estados excitados de las moléculas de los ácidos nucleicos presentan tiempos de vida media que se encuentran en el rango de sub-picosegundos, sugiriendo la presencia de un canal ultrarrápido de conversión interna, lo que normalmente se asocia en la fotoquímica contemporánea a una intersección cónica entre el estado excitado y el fundamental[4]. De esta forma nuestro ADN previene de forma eficaz posibles reacciones en el estado excitado y se revela como un excelente protector solar.

    Soil degradation in natural ecosystem of arid and semi-arid zones of Venezuela due to livestock treading (goats) it is an important problem that affect their environment functions; increase soil erodibility, bulk density, water losses and reduce porosity, water infiltration rate and soil structural stability. The presence of biological crust (BSC) in this type of soil it is very common. The objective of this study was to evaluate the soil surface physical quality through the use of selected indicators, mainly some of that related to structural stability, infiltrability and the prediction of soil erosion risk in two zones of Lara state: 1) Quíbor (QUI) and 2) Humocaro Bajo (HB). The study was conducted on two selected plots (30 m x 20 m) in each zone, with natural vegetation and BSC cover, with areas affected by different degree of compaction due to treading in the paths where the goats are moving. Five sites per plot (50 cm x 50 cm) under vegetation cover and five sites over the path with bare soil were sampled (0-7,5 and 7,5-15 cm depth). The results showed that soil macroaggregate stability (equivalent diameter of aggregates >0,25 mm) was significantly higher (p<0,05 %) in soil with vegetation cover and BSC compared with bare soil. Sealing index, as a measure of aggregate stability, determined in laboratory under simulated rain and expressed as hydraulic conductivity of soil surface sealing (Kse), decreased with decreasing soil vegetation cover and the presence of BSC. However, Ksei (i: inicial) and Ksef (f: final) were significantly greater in soil with more than 75 % of BSC in comparison to bare soils. The sealing index it is used to for to estimate changes in soil water losses. As the sealing index increases, the susceptibility of the soil to undergo surface sealing or slaking decrease. These results suggested that soil physical properties are potential indicators of soil quality with regard to soil erodibility and showed that soils under vegetation cover had

The morphotectonic units of the central Andes from west to east, consist of the Western Cordillera, the active volcanic arc, the Altiplano, an internally drained basin (~4 km elevation), the Eastern Cordillera, the high peaks (~6 km elevation) of an older fold and thrust belt, the Subandean zone, the lower elevation active fold and thrust belt, and the foreland Beni basin. Between northwestern Bolivia and southern Peru, the Altiplano pinches out north of Lake Titicaca as the Andes narrow northward. The CAUGHT seismic instruments were deployed between 13° to 18° S latitudes to investigate the crust and mantle lithosphere of the central Andes in this transitional zone. In northwest Bolivia, perpendicular to the strike of the Andes, there is a total of 275 km of documented upper crustal shortening (15° to 17°S) (McQuarrie et al, 2008). Associated with the shortening is crustal thickening and possibly lithospheric removal as the thickening lithospheric root becomes unstable. An important first order study is to compare upper crustal shortening estimates with present day crustal thickness. To estimate crustal thickness, we have calculated receiver functions using an iterative deconvolution method and used common conversion point stacking along the same profile as the geologically based shortening estimates. In our preliminary results, we observed a strong P to S conversion corresponding to the Moho at approximately 60-65 km depth underneath the

    Medical Physics is an area that applies the principles of physics to medicine, particularly in the prevention, diagnosis and treatment of diseases using ionizing and nonionizing radiation. The main attractive of medical physics is that it has a direct impact on the quality and safety of medical care in humans; this social component with direct implications for the population is of high value for Mexico. This paper describes the concepts of medical physics, trends and the current status of this discipline as a profession, which is directly related to the efforts of clinical research. It is also described what is, in my opinion, the future of medical physics in Mexico, emphasizing the fact that this field requires a substantial boost from universities and hospitals to recruit highly qualified young medical physicists and the support from government agencies such as Secretaria de Salud, Instituto Mexicano del Seguro Social and Instituto de Seguridad y Servicios Sociales para los Trabajadores del Estado through clinical research projects that allow the necessary evolution of medical physics into the hospital setting.

    To identify the cancer incidence and mortality in Mexican Social Security Institute beneficiary (MSSI-B) children during 1996-2013. Both cancer cases (n=4 728) and deaths (n=2 378) were analyzed in MSSI-B children who were registered in five states of the Mexican Republic. The incidence and mortality trends and the incidences (rate x 1 000 000 children / year) of the type of cancer, age, sex, and place of residence were obtained. For both indicators (incidence and mortality), there was a downward trend for the period of 1996-2001 and a stable trend for 2002-2013. This occurred in the overall mortality and incidence trends of the Estado de México and Chiapas and in the leukemia and the acute lymphoid subgroups. The annual overall incidence was 128 cases per 1 000 000 children. Leukemia, lymphomas, and central nervous system tumors were the principal cancer groups. Cancer mortality for the period of 2002-2013 did not diminish. Interinstitutional and/or international research should be designed to improve the care of these children.

    Abstract Pollen types present in samples from corbiculae of Melipona capixaba (Moure and Camargo) (Hymenoptera: Apidae: Meliponina) worker bees were analyzed, as well as pollen samples from food pots inside the hives in three sites located at the bees' original habitat. The aim was to find out the sources used as a trophic resource by this species. The dominant pollen grains in the spectrum of the samples belonged to the families Myrtaceae and Melastomataceae. Eucalyptus was the most frequent pollen type in the corbiculae in Conceição do Castelo municipality; Eucalyptus, Myrcia, and Melastomatacea/Combretaceae in the Fazenda do Estado district; and Eucalyptus and Myrcia in the São Paulo de Aracê district, both in the Domingos Martins municipality. Eucalyptus and Melastomataceae/Combretaceae were the predominant pollen types in the food pots. Eucalyptus was the most prevalent type all year round or most of the year. The most common pollen types in the months that Eucalyptus was not present or dominant in the samples were of remaining native forest species, "ruderal" (field) plants, fruit-bearing plants, and introduced ornamental plants.

    The MesoAmerican Subduction Experiment is a cooperative research project that will help a lot of people to know about the behavior of the subduction of Cocos plate beneath North America, especially in rural communities where its 100 seismic stations are located. MASE is not only focused in its research results, it is also concerned about outreach to the community. To achieve this, MASE conducts an information program on the experiment and seismology, especially targetted to children, to educate them about seismic prevention. MASE field operations in Guerrero, Morelos, Distrito Federal, Estado de México, Hidalgo and Veracruz are ending this year, and our last outreach activity is providing MASE host sites with a poster informing about the experiment and its results. This poster will include pictures about the instruments, a collection of key seismograms, figures of the final seismic model obtained by the MASE research group, showing our enhanced knowledge of the interior of the Earth under each particular site, and a reminder that Mexico is a seismic country and they should be always prepared.

    To design an instrument for measuring beliefs about the social, psychological, and physiological consequences of women's climacteric stage. The study included 340 women affiliated to Instituto de Seguridad y Servicios Sociales para los Trabajadores del Estado (Institute for Social Services and Security for State Workers, ISSSTE) (age mean = 49.46, (SD 7.92). The mean number of pregnancies in the sample was 3.75 (SD 2.57), and the mean number of born children was 3.21 (SD 2.19); 48% of women were premenopausal, 10.9% perimenopausal, and 40.6% postmenopausal. The instrument consisted of 25 items. A factorial analysis with Varimax rotation was carried out. Four factors were confirmed: disadvantages (alpha = 0.769), advantages (alpha = 0.839), physiological (alpha = 0.659), and psychological (alpha = 0.711). This instrument shows good internal consistency, and measures four climacteric belief groups: a) beliefs on disadvantages, b) beliefs on advantages, c) beliefs on physiological ailments, and d) beliefs on psychological symptoms. All three confirmed dimensions of the climacteric phase have been proposed in other studies.

    To analyze the nutritional and metabolic risk factors for Cardiovascular Diseases (CVD) present in a group of people in the city of Maracaibo a study was performed with 209 volunteers (145 women and 64 men) between 20 and 89 years of age who underwent: a) Anthropometric Evaluation: Body Mass Index (BMI) and Waist-to-Hip Ratio (WHR) and Physical Examination: Systolic (SBP) and Diastolic Blood Pressure (DBP); b) Dietetic Evaluation (24 hours recall), and c) Biochemical Evaluation: Glycemia (GLYC), Triglycerides (TG), Total Cholesterol (CHOL), HDL-C, LDL-C and VLDL-C, applying enzymatic methods. It was also investigated, their Age, Family History of Metabolic Alterations (FHMA), physical activity, smoking habits and alcohol consumption. More than 50% of the individuals showed a BMI > 25; 64% of women showed a WHR value > 0.8; 34 and 28% of men and women respectively had a high fat ingestion (HFI); 36% of men had hypertriglyceridemia and high levels of VLDL-C; 41% of women and 30% of men showed decreased HDL-C. A high frequency of FHMA was found in 85% of women and 78% of men followed by sedentary life in 64% of men and 79% of women. The age significantly (p < 0.05) affected the values for WHR, SBP, DBP, GLYC, CHOL, TG, HDL-C, LDL-C and VLDL-C. The dietetic evaluation showed a diet that was low in calories, high in protein, normal in fat and low in carbohydrates. It is concluded that the population elected for this study might be considered under a high risk for CVD, since both nutritional and metabolic factors, as well as the other risk factors analyzed, were present in a high percentage of the individuals studied.

    The Galician coast (NW Iberian Peninsula coast) and mainly the Rias Baixas (southern Galician rias) are one of the most productive ecosystems in the world, supporting a very active fishing and aquiculture industry. This high productivity lives together with a high human pressure and an intense maritime traffic, which means an important environmental risk. Besides that, Harmful Algae Blooms (HAB) are common in this area, producing important economical losses in aquiculture. In this context, the development of an Operational Hydrodynamic Ocean Forecast System is the first step to the development of a more sophisticated Ocean Integrated Decision Support Tool. A regional oceanographic forecasting system in the Galician Coast has been developed by MeteoGalicia (the Galician regional meteorological agency) inside ESEOO project to provide forecasts on currents, sea level, water temperature and salinity. This system is based on hydrodynamic model MOHID, forced with the operational meteorological model WRF, supported daily at MeteoGalicia . Two grid meshes are running nested at different scales, one of ~2km at the shelf scale and the other one with a resolution of 500 m at the rias scale. ESEOAT (Puertos del Estado) model provide salinity and temperature fields which are relaxed at all depth along the open boundary of the regional model (~6km). Temperature and salinity initial fields are also obtained from this application. Freshwater input from main rivers are included as forcing in MOHID model. Monthly mean discharge data from gauge station have been provided by Aguas de Galicia. Nowadays a coupling between an hydrological model (SWAT) and the hydrodynamic one are in development with the aim to verify the impact of the rivers discharges. The system runs operationally daily, providing two days of forecast. First model verifications had been performed against Puertos del Estado buoys and Xunta de Galicia buoys network along the Galician coast. High resolution model results

    The presentation is directed to the description of the actual geodetic infrastructure of Barcelona harbour with three tide gauges of different technologies for sea level determination and contribution to regional sea level rise and understanding past and present sea level rise in the Barcelona harbour. It is intended that the overall system will constitute a CGPS Station of the ESEAS (European Sea Level) and TIGA (GPS Tide Gauge Benchmark Monitoring) networks. At Barcelona harbour there is a MIROS radar tide gauge belonging to Puertos del Estado (Spanish Harbours).The radar sensor is over the water surface, on a L-shaped structure which elevates it a few meters above the quay shelf. 1-min data are transmitted to the ENAGAS Control Center by cable and then sent each 1 min to Puertos del Estado by e-mail. The information includes wave forescast (mean period, significant wave height, sea level, etc.This sensor also measures agitation and sends wave parameters each 20 min. There is a GPS station Leica Geosystems GRX1200 GG Pro and antenna AX 1202 GG. The Control Tower of the Port of Barcelona is situated in the North dike of the so-called Energy Pier in the Barcelona harbor (Spain). This tower has different kind of antennas for navigation monitoring and a GNSS permanent station. As the tower is founded in reclaimed land, and because its metallic structure, the 50 m building is subjected to diverse movements, including periodic fluctuations due to temperature changes. In this contribution the 2009, 2011, 2012, 2013 and 2014 the necessary monitoring campaigns are described. In the framework of a Spanish Space Project, the instrumentation of sea level measurements has been improved by providing the Barcelona site with a radar tide gauge Datamar 2000C from Geonica S.L. in June 2014 near an acoustic tide gauge from the Barcelona Harbour installed in 2013. Precision levelling has been made several times in the last two years because the tower is founded in reclaimed land and

    ça de vida saudável foi estimada pelo método de Sullivan, com base nas informações da Pesquisa Nacional de Saúde, 2013. Foram adotados três critérios para definição de estado "não saudável": autoavaliação de saúde ruim, funcionalidade para realização das atividades da vida diária, e presença de doença crônica não transmissível com grau intenso de limitação. O indicador de nível socioeconômico foi construído com base no número de bens no domicílio e grau de escolaridade do responsável. Para analisar as desigualdades geográficas e por nível socioeconômico, foram calculadas medidas de desigualdade, como a razão, a diferença e o coeficiente angular. A esperança de vida saudável entre os homens variou de 13,8 (Alagoas) a 20,9 (Espírito Santo) para o critério de autoavaliação de saúde ruim. Entre as mulheres, as estimativas correspondentes foram sempre mais altas e variaram de 14,9 (Maranhão) a 22,2 (São Paulo). Quanto à razão de desigualdades por Unidade da Federação, as medianas foram sempre maiores para a esperança de vida saudável do que para a esperança de vida, independentemente da definição adotada para estado saudável. Quanto às diferenças por Unidade da Federação, a esperança de vida saudável chegou a ser sete anos maior em um estado do que em outro. Por nível socioeconômico, foram encontradas diferenças de três e quatro anos, aproximadamente, entre os últimos e primeiro quintos, para homens e mulheres, respectivamente. Além de os indicadores de mortalidade estarem associados às condições de vida, as desigualdades são ainda mais pronunciadas quando o bem-estar e as limitações nas atividades habituais são levados em consideração, mostrando a necessidade de promover ações e programas para diminuir o gradiente socioespacial.

    Chronic kidney disease in children often determines poor nutritional status. Although renal transplantation (RTx) resolves endocrine and metabolic disorders, growth continues to be suboptimal and excessive weight gain may result in obesity. Evaluating the development of height and body mass index in renal transplanted children and adolescents and identifying associated factors with final nutritional status. We reviewed the medical records of 17 patients with regular follow-ups up to 24 months after RTx. Nutritional status was assessed by height-for-age (H/A) and body mass index-for-age (BMI/A). It was considered catch-up growth the increase in z-score H/A ≥ 0.5 standard deviation. Multiple linear regression was used to estimate the influence of factors clinical and demographic variables on anthropometric indicators at 24 months after RTx. Mean age was 9.1 ± 4.1 years old. Twenty-four months after RTx the mean z-score H/A increased from -2.66 ± 1.66 to -1.93 ± 1.08 (p ≤ 0.05), 47.0% of the patients showed catch-up growth and the same proportion showed z-score H/A < -2. Mean z-score BMI/A increased from -0.48 ± 1.03 at RTx to 0.80 ± 0.94 at third month after RTx (p < 0.001) and remained unchanged up to 24 months. The frequency of weight excess increased from 5.9% at RTx to 41.2% at 24 months. Age (r = -0.66; p = 0.006) and z-score H/A (r = -0.72; p = 0.002) at RTx were inversely associated with growth. Twenty-four months after transplant it was verified inadequate growth to recovery from stunting and excessive weight gain. RTx promoted greater growth in the youngest patients and most stunted at RTx. A doença renal crônica em crianças geralmente determina o comprometimento do estado nutricional. Embora o transplante renal (TxR) resolva os distúrbios endócrinos e metabólicos, o crescimento continua a ser inadequado e o ganho de peso excessivo pode resultar em obesidade.

    is postulated that slower subsidence rates dominated during the Paleocene while greater foreland basin subsidence rates during the Eocene-Miocene resulted from the loading of nappe thrust sheets as part of the main construction phases of the Andean orogen. South-southeastward advance and emplacement of the Lara nappes during the oblique transpressive collision of the Caribbean and South American tectonic plates in the Paleocene was further removed from the sites of peat deposition, resulting in slower subsidence rates. Slower subsidence in the Paleocene may have favored the growth of raised mires, generating higher inertinite concentrations through more frequent moisture stress. Consistently low ash yield and sulfur content would be due to the protection from clastic input in raised mires, in addition to the leaching of mineral matter by rainfall and the development of acidic conditions preventing fixation of sulfur. In contrast, peat mires of Eocene-Miocene age encountered rapid subsidence due to the proximity of nappe emplacement, resulting in lower inertinite content, higher and more variable sulfur content, and higher ash yield.

    We have investigated the pinning of magnetic flux quanta by rectangular arrays of nanoscaled magnetic dots. We measured the resistivity vs. magnetic field characteristics using a high magnetic field resolution of up to 0.1 G over the full field range ( 2 kG to 2 kG). By this we the appearance of minima at half and third integer values of the matching field. It is well known that a reconfiguration of the vortex lattice from a rectangular to a square type geometry occurs in rectangular arrays of magnetic dots when the magnetic field is increased over a threshold value H_r. If we lower the magnetic field after crossing H_r, we find that some of the minima at the full integer matching field are missing. This hysteretic behavior occurs only when Hr is exceeded before the subsequent decrease of the magnetic field. We present the experimental results and discuss preliminary models for the explanation of these observations. This work was supported by the grants NSF and DOE. Two of us acknowledge postdoctoral fellowships by the DAAD (Deutscher Akademischer Austauschdienst) (O.M.S.) and the Secretaria De Estado De Educacion Y Universidades (M.I.M.) respectively.

    The diagnostics of impurity density and temperature in the plasma core in tokamak plasmas is carried out by applying the charge exchange recombination spectroscopy (CXRS) technique, where a fast beam of H atoms collides with the plasma particles leading to electron capture reactions with the impurity ions. The diagnostics is based on the emission of the excited ions formed in the electron capture. The application of the CXRS requires the knowledge of accurate state-selective cross sections, which in general are not accessible experimentally, and the calculation of cross sections for the high n capture levels, required for the diagnostics in the intermediate energy domain of the probe beam, is particularly difficult. In this work, we present a lattice numerical method to solve the time dependent Schrödinger equation. The method is based on the GridTDSE package, it is applicable in the wide energy range 1 - 500 keV/u and can be used to assess the accuracy of previous calculations. The application of the method will be illustrated with calculations for collisions of multiply charged ions with H.

    Faults and shear zones recorded in the Monte del Estado and Río Guanajibo serpentinite masses in southwestern Puerto Rico show previously unrecognized southwestward tectonic transport. The orientations of planar and linear structures and the sense of slip along faults and shear zones determined by offset rock layers, drag folds in foliations, and steps in slickensided surfaces and/or S-C fabrics from 1846 shear planes studied at more than 300 stations reveal two predominant groups of faults: 1) northwesterly-striking thrust faults and easterly-striking left-lateral faults and, 2) northwesterly-striking right-lateral faults and easterly-striking thrust faults. Shortening and extension (P and T) axes calculated for geographic domains within the serpentinite reveal early north-trending shortening followed by southwestward-directed movement during which older structures were re-activated. The SW-directed shortening is attributed to transpression that accompanied Late Eocene left-lateral shearing of the serpentinite. A third, younger, group comprising fewer faults consists of northwesterly-striking left-lateral faults and north-directed thrusts that also may be related to the latest transpressional deformation within Puerto Rico. Deformational events in Puerto Rico correlate to tectonic events along the Caribbean-North American plate boundary.

    In the frame of MedEX ("Inter-basin exchange in the changing Mediterranean Sea") Project a 20 years (1989-2008) simulation at 2km resolution covering Gulf of Cadiz and Alboran Sea, forced by 9 km winds (WRF downscaling of ERA-Interim reanalysis), is analyzed and compared with observations. Statistical methods, EOF techniques and two harmonic (including annual and semi-annual frequencies) data fit were performed for the analysis. Modeled SST fields are also compared with long-term (1996-2008) in-situ buoy observations provided by Puertos del Estado (Spain) and satellite derived Pathfinder SST database. Model SSTs generally follow observations data at annual and inter-annual scales with a global error not exceeding 0.17°C (model warmer than SST). No significant warming tendency was observed in both basins during the 20 years and the Interanual variability dominates, with the series showing a cooling period from 1991 to 1993 followed by a warming period started from 1994. In particular we show that SST cooling observed in the early 1990's in the Gulf of Cadiz - Alboran system is associated with the 1991 catastrophic eruption of Pinatubo volcano (Philippines).

    Background: Despite the development of microsurgery and cranial base techniques, the surgical management of Foramen Magnum Meningiomas (FMM) continues to be a technical challenge to neurosurgeons. Controversy concerning the utility of systematic condyle drilling for approaching FMM has been raised. Our aim was to describe the surgical technique, analyze its safety, and the postoperative outcome in 12 consecutive FMM patients. Methods: From 1986 to 2011, 12 patients with FMM underwent operations in the Department of Neurosurgery at Servidores do Estado Hospital and in a private clinic. All patients were operated using a standard suboccipital craniectomy, preserving the occipital condyle, opening of the Foramen Magnum, and ipsilateral removal of the posterior arch of C1. Results: There was no operative mortality, nine patients achieved Glasgow Outcome Scale 4 or 5. Condylar resection was not deemed necessary in any case. Gross total resection was achieved in nine patients. After surgery, four patients developed lower cranial nerve weakness. There was no significant postoperative complication in the remaining patients. The average follow-up is 8.2 years. Conclusion The vast majority of FMM can be safely removed with a retrocondylar lateral suboccipital approach without condylar resection, using meticulous microsurgical techniques. PMID:23776759

    Este artículo documenta una respuesta agregada negativa del logro educativo superior (más de 12 años de escolaridad) en México a la recesión de 1982–83 y el estancamiento que le siguió. La respuesta no fue homogénea entre géneros, regiones y entornos familiares. Los hombres experimentaron una caída en el logro mientras que las mujeres experimentaron un crecimiento más lento. En promedio, los estados con un mayor logro antes del choque experimentaron mayores caídas. La respuesta entre distintos entornos familiares no presenta un patrón claro. Sin embargo, el efecto negativo en el logro se observa incluso entre hermanos. La evidencia sugiere una historia por el lado de la demanda: la caída en el ingreso de los hogares parece ser el determinante de la caída/desaceleración del logro educativo superior. La conclusión es que la recesión y la falta de crecimiento que le siguió tuvieron un efecto negativo importante y duradero en la formación de capacidades en México. PMID:25328251

  10. Effects of correlated hybridization in the single-impurity Anderson model

    2013-03-01

    The development of new materials often dependents on the theoretical foundations which study the microscopic matter, i.e., the way atoms interact and create distinct configurations. Among the interesting materials, those with partially filled d or f orbitals immersed in nonmagnetic metals have been described by the Anderson model, which takes into account Coulomb correlation (U) when a local level (energy Ed) is doubled occupied, and an electronic hybridization between local levels and conduction band states. In addition, here we include a correlated hybridization term, which depends on the local-level occupation number involved. This term breaks particle-hole symmetry (even when U + 2Ed = 0), enhances charge fluctuations on local levels and as a consequence strongly modifies the crossover between the Hamiltonian fixed-points, even suppressing one or other. We exemplify these behaviors showing data obtained from the Numerical Renormalization Group (NRG) computation for the impurity temperature-dependent specific heat, entropy and magnetic susceptibility. The interleaving procedure is used to recover the continuum spectrum after the NRG-logarithmic discretization of the conduction band. Fundação de Amparo à Pesquisa do Estado de São Paulo - FAPESP.

    Resumen Las minorías sexuales y de identidad de género en Guatemala son afectadas de manera desproporcionada por el VIH y otras infecciones transmitidas sexualmente (ITS). Sin embargo, poco se sabe de los factores que contribuyen al riesgo de infección en estas minorías. Investigadores de Estados Unidos y Guatemala quisimos informarnos sobre las necesidades de salud sexual e identificar características de programas de prevención de VIH/ITS para estas minorías. Llevamos a cabo 8 grupos focales con hombres gay, bisexuales y personas transgénero y entrevistas en profundidad con líderes comunitarios. Utilizamos el Método Comparativo Constante para analizar las transcripciones. Identificamos 24 factores que influyen en la salud sexual y 16 características de programas para reducir el riesgo de VIH/ITS en estas poblaciones. La identificación de factores de conductas sexuales de riesgo y de características de programas potencialmente efectivos ofrece gran potencial para desarrollar intervenciones que contribuyan a reducir el riesgo de infección por VIH/ITS en estas minorías en Guatemala.

    Las investigaciones sobre la violencia entre parejas sugieren que las mujeres hispanas están siendo afectadas desproporcionadamente por la ocurrencia y consecuencias de este problema de salud pública. El objetivo del presente artículo es dar a conocer el estado del arte en relación a la epidemiologia, consecuencias y factores de riesgo para VP entre mujeres Hispanas, discutiendo las implicaciones para la investigación y la práctica. Investigaciones han demostrado una fuerte asociación del status socioeconómico, abuso de droga y el alcohol, la salud mental, aculturación, inmigración, comportamientos sexuales riesgosos e historia de abuso con la violencia entre parejas. Sin embargo, más estudios se deben llevar a cabo para identificar otros factores de riesgos y de protección a poblaciones hispanas no clínicas. Mientras que el conocimiento sobre la etiología de la VP entre mujeres Hispanas se expanda, enfermeras y otros profesionales de la salud deben desarrollar, implementar y evaluar estrategias culturalmente adecuadas para la prevención primaria y secundaria de la violencia entre pareja.

    Pollen types present in samples from corbiculae of Melipona capixaba (Moure and Camargo) (Hymenoptera: Apidae: Meliponina) worker bees were analyzed, as well as pollen samples from food pots inside the hives in three sites located at the bees’ original habitat. The aim was to find out the sources used as a trophic resource by this species. The dominant pollen grains in the spectrum of the samples belonged to the families Myrtaceae and Melastomataceae. Eucalyptus was the most frequent pollen type in the corbiculae in Conceição do Castelo municipality; Eucalyptus, Myrcia, and Melastomatacea/Combretaceae in the Fazenda do Estado district; and Eucalyptus and Myrcia in the São Paulo de Aracê district, both in the Domingos Martins municipality. Eucalyptus and Melastomataceae/Combretaceae were the predominant pollen types in the food pots. Eucalyptus was the most prevalent type all year round or most of the year. The most common pollen types in the months that Eucalyptus was not present or dominant in the samples were of remaining native forest species, “ruderal” (field) plants, fruit-bearing plants, and introduced ornamental plants.

    Brunini, A.; Yokoyama, T.

    Recientemente, se ha demostrado mediante extensas integraciones numéricas, que la rotación de Marte pasó repetidamente por estados caóticos de movimiento, debido al pasaje por zonas de resonancia spin - órbita. En dichas circunstancias, la oblicuidad marciana pudo haber sufrido grandes excursiones de varias decenas de grados. Las consecuencias de dichas variaciones son de extrema importancia en el contexto de la búsqueda de manifestaciones de vida fósil en dicho planeta. El estudio de la dinámica orbital del satélite más exterior de Marte, Deimos, nos ha permitido comprobar, en el marco de las distintas teorías sobre su orígen, que la oblicuidad de Marte dificilmente pudo haber sufrido variaciones que la aparten más de 10o respecto de actual valor. Este resultado parece ser mucho más robusto que las simulaciones numéricas de Touma y Wisdom asi como las de Laskar y Robutel, lo que permite poner cotas más severas a la evolución paleoclimática de Marte.

    This study proposes a reflection on the uses and future prospects of hospital-based health surveillance based on the account of a pioneering experience in hospital epidemiology, the epidemiology service at the Hospital Federal dos Servidores do Estado - HFSE, which served as the basis for the creation of epidemiologic surveillance units in municipal and state hospitals in Rio de Janeiro, Brazil. The epidemiology service has combined epidemiological surveillance, continuing education, in-service training, research, and health service evaluation since 1986. The service is part of the national epidemiological surveillance network and was responsible for the notification of 55,747 cases between 1986 and 2016, most of which were the result of active search. The integration of various levels of health surveillance and health care makes classical control activities more agile and provides instruments for measuring. The important role played by the service in human resources training is evident in the training of 1,835 medical interns and 78 residents up to 2016. In addition, this experience has served as the basis for the implantation of several other hospital epidemiological surveillance units. Current challenges include the promotion of effective communication and coordination among the other health surveillance committees.

    To evaluate the relation between diabetes-related distress and the clinical and sociodemographic characteristics of type 2 diabetes mellitus patients. A cross-sectional study based on a secondary analysis of data collected at a specialized care outpatient center in Brazil. Participants completed a questionnaire on sociodemographic and clinical characteristics and the Brazilian version of the Diabetes Distress Scale (B-DDS). About 31% of the 130 eligible patients reported diabetes distress, and the mean B-DDS score was 2.6. Multiple regression analysis showed the B-DDS score was positively correlated with marital status (p=0.0230), use of diet and physical activities for diabetes management (p=0.0180), and use of insulin therapy (p=0.0030). The "emotional burden", "regimen-related distress", and "interpersonal distress" domains from B-DDS were associated with the use of insulin therapy (p=0.0010), marital status (p=0.0110), and the presence of three or more comorbidities (p=0.0175). These findings suggest the clinical and sociodemographic variables are relatively weak predictors of diabetes-related distress. The highest scores in the B-DDS were observed in the emotional burden domain, indicating the presence of diabetes distress among the participants of the study.

    The XXXVII Brazilian Meeting on Nuclear Physics (or XXXVII RTFNB 2014) gave continuity to a long sequence of workshops held in Brazil, devoted to the study of the different aspects of nuclear physics. The meeting took place in the Maresias Beach Hotel, in the town of Maresias (state of São Paulo) from 8th to 12th September 2014. Offering gentle weather, a charming piece of green land of splendid natural beauty with beach and all amenities, the place had all the conditions for very pleasant and fruitful discussions. The meeting involved 162 participants and attracted undergraduate and graduate students, Brazilian and South American physicists and invited speakers from overseas (USA, Italy, Spain, France, England, Switzerland, Germany and South Corea). In the program we had plenary morning sessions with review talks on recent developments in theory, computational techniques, experimentation and applications of the many aspects of nuclear physics. In the parallel sessions we had a total of 58 seminars. This volume contains 60 written contributions based on these talks and on the poster sessions. Evening talks and poster sessions gave still more insight and enlarged the scope of the scientific program. The contributed papers, representing mainly the scientific activity of young physicists, were exhibited as posters and are included in the present volume.

    This work discusses the management of the work relations in the context of the new systems of public vs. private relation in health, having as reference the experience of the habilitation of Social Organizations (SO), responsible for the administration of a group of hospitals in the state of São Paulo. The urgency in this kind of management supported on the legal figure of the SO has implications in the management of Human Resources in Health (HRH) through the adoption of flexibilization mechanisms which include ways of selection, hiring and dismissal, payment rules and functional progression similar to the actions adopted by the market. The establishment of this sort of administration refers to the new paradigm proposed by the managerial administrative reform which suggests the exhaustion of the bureaucratic model to promote adjustment of the public administration to the transformations originated in the new stage of internationalization of the economy and its unfolding in the work world, as well as to the new standards of requirements of performance of the public field. Aspects related to the management of HHR are approached in the two ruling modalities in the Secretaria de Estado da Saúde de São Paulo: Direct Administration Hospitals (DAH) and units organized under the SO model (SOH).

    The shallow-to-deep convective transition over land typically refers to the growth of the convective boundary layer after sunrise, followed by the development of cumulus congestus clouds in the late morning/early afternoon and transitioning to deep convective clouds in the late afternoon and early evening. Under favorable conditions, this diurnal convection can result in organized mesoscale convective systems (MCSs) that last through the following morning. While many studies have focused on improving this process in models, the shallow-to-deep transition remains poorly represented especially over land. The recent DOE ARM mobile facility deployment in the Amazon, launched as part of GOAmazon, along with a dense GNSS network supported by Universidade do Estado do Amazonas (UEA)/Instituto Nacional de Pesquisas Espaciais (INPE) and co-located with the CHUVA Project sites for GOAmazon, are used here to examine land-based convective processes in the tropics. In particular, this aspect of a larger study of the shallow-to-deep transition explores the role of large-scale intraseasonal wave activity in supporting the growth of MCSs over the GoAmazon region. These results will be placed in the context of local forcing mechanisms for convective growth over the region in ongoing work.

    Childhood obesity is a global problem, sociodemographic and cultural factors influence its presence. An analysis of disparities in the prevalence of childhood obesity in Peru was made by sex and region in 2015. Analysis of the information reported by the Sistema de Información del Estado Nutricional of the number of obesity cases in 2,336,791 children under five years, evaluated in public health facilities during 2015. The distribution of obesity cases was analyzed by sex and region of residence, also a spatial projection of the regional prevalence of obesity and the prevalence differences between men and women was performed. Data from 2,336,791 children under five was analyzed. An obesity prevalence of 1.52% (girls: 1.3% and boys: 1.7%) was found; the highest prevalence were observed in urban areas (girls: 1.5% and boys: 1.9%) and on the Costa (girls: 1.9% and boys: 2.5%). Highest prevalence of obesity were in Tacna (girls: 3.2% y boys: 3.9%), Moquegua (girls: 2.4% y boys: 3.1%) and Callao (girls: 2.3% y boys: 2.8%). Childhood obesity predominates on the coast and in urban areas of Peru particularly among boys. The regions of higher prevalence of obesity were Tacna Moquegua and Callao.

    This study aimed to describe the influence of socio-economic status (SES) on the prevalence sedentary behaviours among Spanish adolescents. Cross-sectional data from Spanish adolescents from the Alimentación y Valoración del Estado Nutricional de los Adolescentes (AVENA) Study (2002). A national representative sample of 1776 adolescents aged 13-18.5 years provided information about time spent watching television (TV), playing with computer or videogames and studying. Parental education and occupation were assessed as SES. Participants were categorized by gender, age, parental education and occupation. Logistic regression models were used. No gender differences were found for TV viewing. For computer and videogames use (weekdays), more boys played >3 h/day (P < 0.001), whereas a higher percentage of girls reported studying >3 h/day (P < 0.001). Among boys, parental education and occupation were inversely associated with TV viewing, parental occupation directly associated with study and maternal education inversely with computer and videogames use during weekdays (all P < 0.05). For girls, parental occupation was inversely associated with TV viewing. Spanish adolescents presented different sedentary patterns according to age, gender and SES. Boys reported more time engaged in electronic games, whereas girls reported more time studying. Parental occupation had more influence than parental education on the time spent in sedentary behaviours.

    Science and technology disclosure is an integral part of our scientific work as researches; it is an induction process for children, young people and teachers of primary and secondary schools in the state of Queretaro. Education must be offered in a clear and objective way, it allows to the students apply the acquired knowledge to understand the world and improve his quality of life. Nowadays, the Centro de Investigacion en Ciencia Aplicada y Tecnologia Avanzada of the Instituto Politecnico Nacional Unidad Queretaro (CICATA-IPN Queretaro) together with the Consejo de Ciencia y Tecnologia del Estado de Queretaro (CONCYTEQ) have implemented the "Science and Technology for Children" program (Ciencia y Tecnologia para Ninos - CTN), it allows to the educative sector obtain information through the CONCYTEQ web page. The fist stage of the program was the development of two subjects: the brochure titled "Petroleum, Nonrenewable Natural Resource that Moves the World" and the manual "Experiments of Physics".

    Estuda-se as características físicas das fontes supermoles (de raios X (SSS), utilizando dados ópticos e em altas energias, no âmbito de um trabalho de IC. Trata-se de binárias que apresentam espectro X muito mole, baixas temperaturas e altas luminosidades bolométricas. Esse sistemas são compostos por uma anã branca realizando fusão em sua superfície, a partir de matéria perdida pela estrela companheira. Os resíduos de fusão se acumulam na superfície da anã branca, e essa pode ultrapassar o limite de Chadrasekhar, produzir um colapso gravitacional, sendo esse um dos cenários propostos para as explosões de SN Ia. Apresentamos nesta comunicação o estado da arte das características físicas das fontes SSS, situando-as no âmbito das VCs. Procuramos também situar esses objetos em relação às variáveis galácticas V Sge, na medida em que os dois grupos apresentam certas caracerísticas bastante semelhantes.A metodologia adotada é aquela pedagógico-cognitiva clássica de um trabalho de IC na área de ciências exatas.

Our hypothesis is that tutored theoretical-practical training is a more cost-effective option for teaching undergraduate students to detect caries lesions. If our hypothesis is confirmed, the use of laboratory training in conjunction with theoretical classes could be used as an educational strategy in Cariology to improve the development of undergraduate students' skills in the detection of caries lesions and clinical decision-making. ©Mariana Minatel Braga, Tathiane Larissa Lenzi, Fernanda Rosche Ferreira, Fausto Medeiros Mendes, Daniela Prócida Raggio, José Carlos Imparato, Marcelo Bonecker, Ana Carolina Magalhães, Linda Wang, Daniela Rios, Juliano Pelim Pessan, Cristiane Duque, Maria Augusta Bessa Rebelo, Ary Oliveira Alves Filho, Marina De Deus Moura Lima, Marcoeli Silva Moura, Alessandro Diogo De Carli, Mariane Emi Sanabe, Maximiliano Sergio Cenci, Elenara Ferreira Oliveira, Marcos Britto Correa, Rachel Oliveira Rocha, Julio Eduardo Zenkner, Pedroza Uribe Murisí, Stefania Martignon, Juan Sebastian Lara, Fatima Gabriela Aquino, Alfredo Carrillo, Chun Hung Chu, Chris Deery, David Ricketts, Paulo Melo, José Leopoldo Ferreira Antunes, Kim Rud Ekstrand, IuSTC Group.

    prevent the disease from spreading throughout the whole territory of São Paulo or to at least reducing its expansion speed. Avaliar, no espaço e espaço-tempo, a ocorrência da leishmaniose visceral em humanos no estado de São Paulo, Brasil. Considerou-se como população de estudo os casos autóctones e óbitos por leishmaniose visceral em humanos ocorridos em São Paulo entre 1999 e 2013 e, como área de estudo, a região oeste do estado. Construíram-se mapas temáticos que mostraram a disseminação da leishmaniose visceral em humanos nos municípios. Ferramentas de análise espacial Kernel e razão Kernel foram utilizadas para obter, respectivamente, a distribuição dos casos e óbitos e a distribuição da incidência e mortalidade. Utilizaram-se estatísticas de varredura para identificar aglomerados espaciais e espaço-temporais de casos e óbitos. Os casos de leishmaniose visceral em humanos, no período de estudo, ocorreram na parte ocidental de São Paulo e sua expansão territorial seguiu principalmente o curso da rodovia Marechal Rondon, no sentido oeste-leste. As incidências foram caracterizadas como duas sequências de elipses concêntricas com intensidade decrescente. A primeira, com maior intensidade, teve epicentro no município de Castilho (cruzamento da rodovia Marechal Rondon com a divisa com o estado de Mato Grosso do Sul) e a segunda, em Bauru. A mortalidade apresentou comportamento similar ao da incidência. Os aglomerados espaciais e espaço-temporais de casos coincidiram com as duas áreas de maiores incidências. Ambos os aglomerados espaço-temporais identificados, mesmo sem coincidirem temporalmente, tiveram início após três anos da detecção dos casos humanos e tiveram a mesma duração, seis anos. A expansão da leishmaniose visceral em São Paulo vem ocorrendo no sentido oeste-leste, com destaque ao papel das rodovias, especialmente a Marechal Rondon, neste processo.

    A combinacao das caracteristicas do diamante microcristalino (MCD) e nanocristalino (NCD), tais como elevada adesao do MCD e a baixa rugosidade superficial e baixo coeficiente de atrito do NCD, e ideal para aplicacoes tribologicas exigentes. Deste modo, o presente trabalho centrou-se no desenvolvimento de revestimentos em multicamada MCD/NCD. Filmes com dez camadas foram depositados em amostras de cerâmicos de Si3N4 pela tecnica de deposicao quimica em fase vapor assistida por filamento quente (HFCVD). A microestrutura, qualidade do diamante e adesao foram investigadas usando tecnicas como SEM, AFM, espectroscopia Raman, DRX, indentacao Brale e perfilometria otica 3D. Diversas geometrias para aplicacoes distintas foram revestidas: discos e esferas para testes tribologicos a escala laboratorial, e para testes em servico, aneis de empanques mecânicos e pastilhas de corte para torneamento. Nos ensaios tribologicos esfera-sobre-plano em movimento reciproco, sob 10-90% de humidade relativa (RH), os valores medios dos coeficientes de atrito maximo e em estado estacionario sao de 0,32 e 0,09, respetivamente. Em relacao aos coeficientes de desgaste, observou-se um valor minimo de cerca de 5,2x10-8 mm3N-1m-1 para valores intermedios de 20-25% de RH. A humidade relativa tem um forte efeito sobre o valor da carga critica que triplica a partir de 40 N a 10% RH para 120 N a 90% de RH.

    Resumen Durante cinco años, un torbellino cotidiano de tiroteos, apuñalamientos y asaltos afectó a la venta de drogas al aire libre en el vecindario puertorriqueño de Filadelfia, donde residíamos y conducíamos nuestro trabajo de campo. La industria de los narcóticos ha venido a llenar el vacío que dejó la desindustrialización, convirtiendo al antiguo distrito fabril de la ciudad en un mercado de narcóticos a cielo abierto que emplea en sus niveles más bajos a jóvenes puertorriqueños y cuyos clientes son principalmente heroinómanos blancos de bajos recursos. La capacidad para movilizar la furia asegura el éxito en la economía de las drogas, garantiza protección en las cárceles y le provee un ingreso mínimo a una población de bajos recursos estigmatizada cuyos miembros frecuentemente reciben diagnósticos médicos de discapacidad cognitiva. Muchos residentes buscan alianzas en redes sociales que los comprometen a participar en intercambios solidarios de violencia auxiliar. Una dinámica de acumulación primitiva corporizada mata, hiere, discapacita o encarcela a la mayoría de estos empleados de bajo nivel y a sus clientes. Los inflados márgenes de ganancia alrededor de esta dinámica dependen de la violencia y la coerción. Un habitus furibundo impulsa a los vendedores callejeros a defender violentamente el micro monopolio de poder de sus jefes en la economía subterránea como si fuese un asunto de diversión. Estos miembros de los niveles más bajos de la industria del narcotráfico se apresuran a fraguar transacciones comerciales en ausencia de un marco legal en un ambiente de escasez que sin embargo se ve inundado por enormes flujos de dinero, drogas adictivas y armas automáticas. Tras las drásticas reformas a los programas de seguridad social, la mano izquierda del Estado, en la forma de los servicios sociales, intenta prolongar los subsidios para individuos vulnerables diagnosticándolos como discapacitados cognitivos permanentes

The official data estimate an emission of 15327 million tons per year of CO2eq (60% by LDV, 38% HDV and 2% motorcycles) and 128 million tons per year of CO. The top-down estimative based on tunnel measurements resulted in values approximately 5 times higher, being the difference more attributable to the estimative of the diesel emission factor. The uncertainties are related to the deterioration of the emission factor with time and the driving pattern. The diurnal variation of CO2 atmospheric concentration is characterized by the mobile source emission pattern. CETESB. Relatório Anual de Qualidade do Ar no Estado de São Paulo 2012.

Brazil?s national football stadium, the Estado Nacional, lies near the heart of the capital city of Brasilia. The new roof appears as a brilliant white ring in this image. The stadium is one of Brasilia?s largest buildings. Renovation began in 2010 and it is now the second most expensive stadium in the world, after Wembley Stadium in London, UK. To accommodate expected World Cup fans from all over the world, renovations for all modes of transportation, particularly airports, have been put in place in Brasilia and other host cities. Brasilia?s international airport can be seen lower left on the far side of Lake Paranoa. Brasilia is widely known for its modern building designs and city layout. Space station crew members have the best view of the city?s well-known ?swept wing? city layout ? giving the sense of a flying bird ? expressed in the curves of the boulevards (top). The stadium occupies the city center between the wings. The President Juscelino Kubitschek Bridge crosses the lake at bottom right. Its 1200-meter span gives scale to the city and stadium.

  20. Periodic vortex pinning by regular structures in Nb thin films: magnetic vs. structural effects

    The defects present in a superconducting material can lead to a great variety of static and dynamic vortex phases. In particular, the interaction of the vortex lattice with regular arrays of pinning centers such as holes or magnetic dots gives rise to commensurability effects. These commensurability effects can be observed in the magnetoresistance and in the critical current dependence with the applied field. In recent years, experimental results have shown that there is a dependence of the periodic pinning effect on the properties of the vortex lattice (i.e. vortex-vortex interactions, elastic energy and vortex velocity) and also on the dots characteristics (i.e. dot size, distance between dots, magnetic character of the dot material, etc). However, there is not still a good understanding of the nature of the main pinning mechanisms by the magnetic dots. To clarify this important issue, we have studied and compared the periodic pinning effects in Nb films with rectangular arrays of Ni, Co and Fe dots, as well as the pinning effects in a Nb film deposited on a hole patterned substrate without any magnetic material. We will discuss the differences on pinning energies arising from magnetic effects as compared to structural effects of the superconducting film. This work was supported by NSF and DOE. M.I.

    ABSTRACT Objective: To evaluate the impact of atopic dermatitis on the quality of life of pediatric patients in the age group of 5-16 years, and their parents, assisted at the Dermatology Department of Universidade do Estado do Pará in 2015. Methods: A cross-sectional study including 51 patients and their guardians, to whom two questionnaires about the quality of life were applied, the Children’s Dermatology Life Quality Index (CDLQI) and the Dermatitis Family Impact (DFI). To evaluate the severity of the disease, the researchers applied the Severity Scoring of Atopic Dermatitis (SCORAD) index. The Pearson Product-Moment Correlation Coefficient (PPMCC) evaluated the correlation between CDLQI, DFI, SCORAD, and the contingency coefficient C evaluated the association between the qualitative variables, considering p<0.05 significant. Results: Of the patients, 55% were female. The average age was 9.5±3.2 years, and 41% had family income up ≤1 minimum wage. The average score was 5.4±5.1 for CDLQI, 6.6±4.5 for DFI, and 28.3±19.8 for SCORAD. The correlation among the scores CDLQI, DFI, and SCORAD was significant by the PPMCC (p<0,001). Conclusions: Atopic dermatitis affects the quality of life of both children and their guardians, and indicates the importance of including the study of quality of life as a complement to clinical evaluation.

    Background The relationship between hyperglycemia and prostate cancer remains controversial. According to current hypotheses, elevated serum glucose levels may lead to disease development or disease prevention. Our study examined the potential correlation between pre-operative glycemic levels of patients with prostate cancer and the grade of tumor aggressiveness. Method We studied the case files of patients with a diagnosis of prostate cancer who had received putatively curative cancer surgery at the Urology Department of the Servidores do Estado Federal Hospital (RJ/Brazil). We transcribed information related to glycemia - collected up to 3 months before the surgery - and the histopathological grade of tumor aggressiveness (Gleason score) of the surgically removed prostates. Results We analyzed 42 people who met the inclusion criteria. Based on Gleason scores, among the normoglycemic patients, we detected low, moderate, and highly aggressive neoplasias in 13%, 53%, and 36% of the cases, respectively. For the hyperglycemic group, these rates were 30%, 60%, and 10%, respectively. Normoglycemic patients had primary Gleason grade 3 in 40% of the cases and grade 4 in 60% of the cases. For the hyperglycemic patients, these rates were 90% and 10%, respectively (P < 0.05 vs. grade 3 group). Conclusion Both Gleason score and primary Gleason grade were lower in hyperglycemic patients with prostate cancer than in normoglycemic patients, suggesting a “protective action” of hyperglycemic states.

    Tuberculosis (TB) is an infectocontagious respiratory disease caused by members of the Mycobacterium tuberculosis complex. A 7 base pair (bp) deletion in the locus polyketide synthase (pks)15/1 is described as polymorphic among members of the M. tuberculosis complex, enabling the identification of Euro-American, Indo-Oceanic and Asian lineages. The aim of this study was to characterise this locus in TB isolates from Mexico. One hundred twenty clinical isolates were recovered from the states of Veracruz and Estado de Mexico. We determined the nucleotide sequence of a ± 400 bp fragment of the locus pks15/1, while genotypic characterisation was performed by spoligotyping. One hundred and fifty isolates contained the 7 bp deletion, while five had the wild type locus. Lineages X (22%), LAM (18%) and T (17%) were the most frequent; only three (2%) of the isolates were identified as Beijing and two (1%) EAI-Manila. The wild type pks15/1 locus was observed in all Asian lineage isolates tested. Our results confirm the utility of locus pks15/1 as a molecular marker for identifying Asian lineages of the M. tuberculosis complex. This marker could be of great value in the epidemiological surveillance of TB, especially in countries like Mexico, where the prevalence of such lineages is unknown. PMID:24037193

    Comadia redtenbacheri (Hammerschmidt) (Agave Red Worm) is the only member of the family Cossidae that has been described as a phytophagous specialist of the plant genus Agave, which is mainly distributed in México. A new extraction protocol adapted from Stewart Via (1993) has been implemented for sequencing the COI gene from samples collected in five states of the North Central (Querétaro and Zacatecas), South Central (Estado de México) and East Central (Hidalgo and Tlaxcala) regions of México with the purpose of contributing to delineation of the species. A Maximum Likelihood (ML) tree based on these COI sequences as well as COI sequences from other Cossinae species was developed to complement the existing morphological and taxonomic approaches to delineation of this species. As expected, our Comadia samples cluster together within a monophyletic clade that includes four C. redtenbacheri sequences previously reported. This group seems to be consistent with our reconstruction, which is supported by a bootstrap value of over 99%. The closely related branches associated with the latter group include organisms known to be the plant and tree borers of the Cossinae subfamily. The COI sequences from our samples were analyzed to determine the percentage of identity among the C. redtenbacheri in a first attempt to detect differences in the sequence that matches a particular region of México.

De estas 130 provincias, 23 se encuentran en Suramérica, Centroamérica, y la región del Caribe (fig. 1). El estudio comprendió desde las provincias de petróleo establecidas con un largo historial de producción, como la Cuenca de Maracaibo, hasta las provincias fronterizas de poca o ninguna producción, como la Cuenca de Guyana-Suriname. No todas las provincias con historial de producción o con potencial de producción fueron evaluadas en el Estudio Evaluativo USGS 2000. Al presente, el USGS está evaluando muchas de las provincias restantes de petróleo y gas, en Centro y Suramérica. En cada provincia hemos (1) definido geológicamente el total de los sistemas de petróleo, (2) definido las unidades evaluadas que forman parte de todos los sistemas de petróleo, y (3) evaluado el volumen potencial de petróleo y gas convencional en cada unidad evaluada.

    The occurrence of a brain tumor or intracranial vascular lesion during pregnancy is a rare event, but when it happens, it jeopardizes the lives of both the mother and infant. It also creates challenges of a neurosurgical, obstetric, and ethical nature. A multidisciplinary approach should be used for their care. Between 1986 and 2015, 12 pregnant women diagnosed with brain tumors and 17 women with intracranial vascular lesion underwent treatment at the Neurosurgery Department of the Servidores do Estado Hospital and Rede D'Or/São Luis. The Neurosurgery Department teamed up with Obstetrics Anesthesiology Departments in establishing the procedures. The patients' records, surgical descriptions, imaging studies, and histopathological material were reviewed. Among 12 patients presenting with brain tumors, there were neither operative mortality nor fetal deaths. Among the vascular lesions, aneurysm rupture was responsible for bleeding in 6 instances. Arteriovenous malformation was diagnosed in 7 patients. In this subgroup, the maternal and fetal mortality rates were 11.7% and 23.7%, respectively. We can assert that the association between a brain tumor and vascular lesions with pregnancy is a very unusual event, which jeopardizes both the lives of the mother and infant. It remains incompletely characterized due to the rare nature of these potentially devastating events. Knowing the exact mechanism responsible for the interaction of pregnancy and with these lesions will improve the treatment of these patients.

    In October 1899, the bubonic plague arrived in Brazil through the port of Santos. A city of intensive port activity, Santos was the gateway for a plague epidemic that devastated several cities in Brazil in the early 20th century and prompted joint action by several states to fight it. More importantly, given the difficulties and delays in importing anti-plague serum from Europe, it led to the creation of the Butantan Institute in Sao Paulo (in 1899) and the Municipal Serotherapeutic Institute in Rio de Janeiro (in 1900), which developed and standardized anti-plague serum and vaccines according to the particular conditions of the country. Until then, public health efforts had been isolated and had not reached the whole country. Oswaldo Cruz, newly arrived after three years of specialization at the Pasteur Institute in Paris, worked with scientists Adolfo Lutz and Vital Brazil on identifying the plague in Santos. This article analyzes the arrival of the bubonic plague epidemic in the state of Sao Paulo and the public health measures taken to combat the disease and provide patient care in the early part of the 20th century. The primary sources for this analysis were the São Paulo newspapers, especially O Estado de Sao Paulo, and reports from the Ministry of Justice and the President of the State of Sao Paulo.

    The realization of a spintronic device using topological insulators is not trivial, because there are inherent difficulties in achieving the surface transport regime. The majority of 3D topological insulators materials (3DTI) despite of support helical metallic surface states on an insulating bulk, forming topological Dirac fermions protected by the time-reversal symmetry, exhibit electronic scattering channels due to the presence of residual continuous bulk states near the Dirac-point. From ab initio calculations, we studied the microscopic origin of the continuous bulk states in rhombohedral topological insulators materials with the space group D3d 5 (R 3 m) , showing that it is possible to understand the emergence of residual continuous bulk states near the Dirac-point into a six bands effective model, where the breaking of the R3 symmetry beyond the Γ point has an important role in the hybridization of the px, py and pz atomic orbitals. Within these model, the mechanisms known to eliminate the bulk scattering, for instance: the stacking faults (SF), electric field and alloy, generated the similar effect in the effective states of the 3DTI.

    The history of the hospital of Tehuacán, the second city importance in Puebla State, began in 1744, when the Hospital de San Juan de Dios (Hospital of St. John) was founded; in 1820, it was converted into the Municipal of Civil Hospital. The medical establishement continues to provide services to the poor to this day annual also covers health public workers of services for the municipality. The Hospital de la Cruz Roja Mexicana (The Mexican Red Cross Hospital) was created in 1934 provide medical services for accident victims: The hospital services of the Mexican Institute of Social Security (IMSS) began in 1953; an earthquake destroyed the building in 1973, and a new hospital was inaugurated in 1979; at present, it readers services to 98,000 persons. The Sanatorio del Sagrado Corazón (Sacred Heart Sanatorium) is a private religious institution founded at the beginning of the second half the 20th century. In 1996, the Hospital General (General Hospital) began to provide services, takes care of the poor of the geographical region, and is financed with federal funds. The Instituto de Seguridad y Servicios Sociales para Trabajadores del Estado (Institute of Securtiy and Social Services for the Workers of the State, ISSSTE) has a small hospital with 10 beds, it was founded in 1995.

    The prevalence of serum markers of viral hepatitis in health-care workers seems to be similar to that described in the general population, even though this group would appear at increased risk because exposure to potentially infectious material. There is scarce information available in Mexico in this regard. To define the prevalence of serum markers for hepatitis C (anti-HCV antibodies) and hepatitis B (hepatitis B surface antigen, HBsAg) in health-care workers at the Instituto de Seguridad Social del Estado de Mexico y Municipios (ISSEMYM) and to establish the presence of viremia in subjects with positive serum markers. Health-care workers from ISSEMyM with unknown hepatitis serologic status participated voluntarily in this trial. They completed a written questionnaire detailing potential risk factors for viral hepatitis and provided a blood sample. A total of 374 health-care workers were included. Seven subjects (1.8%) were positive, 5 for anti-HCV antibodies (1.3%) and 2 for HBsAg (0.5%). None of these subjects had detectable serum HCV RNA or HBV DNA on further testing. The frequency of positive serum markers for viral hepatitis in this group of healthcare workers is similar to the estimated prevalence among the general population in Mexico. No case of active infection defined by positive viremia was encountered in this group of subjects.

    Atmospheric concentrations of nitrous acid, nitric acid, nitrate and sulfate particles were obtained in this study from April to June 2008 in the center of the city of Guadalajara, while concentrations of ozone, sulfur dioxide, nitrogen dioxide and meteorological parameters (temperature and relative humidity), were acquired by the Secretaría del Medio Ambiente para el Desarrollo Sustentable del Estado de Jalisco (SEMADES). The results showed that nitric acid (2.7 μg m(-3)) was 2.7 times higher than nitrous acid (1.0 μg m(-3)). The sulfur dioxide (SO(2)) concentration indicated an opposite trend to sulfate (SO(4) (2-)), with the average concentration of SO(2) (6.9 μg m(-3)) higher in almost the entire period of study. The sulfur conversion ratio (Fs, 24.9%) and nitrogen conversion ratio (Fn, 6.2%), were revealed to be similar to that reported in other urban areas during warm seasons. It is also noted that ozone is not the main oxidizer of nitrogen dioxide and sulfur dioxide. This determination was made by taking into account the slightly positively correlation determined for Fn (r(2) = 0.084) and Fs (r(2) = 0.092) with ozone that perhaps suggests there are other oxidizing species such as the radical OH, which are playing an important role in the processes of atmospheric oxidation in this area.

    Recently re-named as a sub-species of Mellinus arvensis, Mellinus arvensis obscurus Handlirsch 1888 was investigated ecologically and morphologically in Nepal, in order to underline the most important differences with the well known M. arvensis arvensis. Mellinus arvensis obscurus females nested in clumped aggregations on inclined plains at high altitudes, both on sunny bare soil and on a shaded grassy one. Beginning of monsoon season probably interfered with wasp activity, and females performed few provisioning flights during the day. Prey consisted of a broad range of Diptera, except for one case of a spider. Many females were observed not provisioning amore » nest but floating on the nesting site, and many intraspecific interactions suggested a high degree of usurpation attempts. At least one species of flies and two of ants probably acted as natural enemies of the wasp. Morphological observations on females showed that the Nepal population shares more similarities (shape of tergite I, body punctation) with the European populations than with the closer Japanese population; melanization is strong, according to west-east and altitudinal cline. The mature larva of M. arvensis obscurus Handlirsch is described, illustrated, and compared with the other mature larva of the genus. The differences between both larvae mainly lie in the presence/absence, and number or differentiation of integumental structures. We conclude that morphological traits are more important than ecological and behavioral ones in distinguishing M. arvensis obscurus from M. arvensis arvensis.

    conclusively been shown to infect people before. This unequivocal demonstration of zoonotic transmission, 50 years after the only previous report of P simium in people, leads to the possibility that this parasite has always infected people in this region, but that it has been consistently misdiagnosed as P vivax because of an absence of molecular typing techniques. Thorough screening of local non-human primates and mosquitoes (Anopheline) is required to evaluate the extent of this newly recognised zoonotic threat to public health and malaria elimination in Brazil.

    Tarjuelo, Juan Lopez

    Introduccion: En la administracion de la radioterapia intervienen profesionales y equipos de tratamiento, por lo que existe el riesgo de error y se precisa que dicho equipamiento funcione conforme a lo esperado. A los radiofisicos les corresponde participar en las actividades de garantia o aseguramiento de la calidad, incluyendo el control de calidad de los equipos, y en la evaluacion de los riesgos asociados. La radioterapia intraoperatoria (RIO) es una tecnica radioterapica de intensificacion de dosis, altamente selectiva, dirigida a volumenes anatomicos restringidos durante el tratamiento quirurgico oncologico, basada en la administracion de una dosis absorbida alta por medio de un haz de electrones tras el examen visual directo del lecho tumoral. Como incorporar los ultimos avances en el refuerzo de la seguridad en radioterapia es una tarea ambiciosa y compleja, resulta mas concreta y de inmediata aplicacion su introduccion en la RIO. El objetivo es analizar los elementos que reducen los riesgos y aumentan la seguridad en la RIO y su dosimetria, y valorar la funcion del radiofisico en esta labor. Material y metodos: Se emplearon el planificador Radiance de GMV y el acelerador lineal de los tratamientos de RIO Elekta Precise, controlado con el verificador diario de haces Daily QA Check 1090 y medido con las camaras de ionizacion PPC 40, FC65-G y FC65-P de PTW-Freiburg, a su vez verificadas con fuentes radiactivas adecuadas de estroncio-90 modelos CDP y CDC de IBA Dosimetry. Se realizo un analisis de modos de fallo y efectos (failure mode and effect analysis, FMEA) con el fin de identificar los elementos que forman la RIO y aplicar las herramientas necesarias para la minimizacion de los riesgos y la mejora de la seguridad en la tecnica. Se estudiaron las verificaciones diarias de dicho acelerador Precise con el control estadistico de procesos (statistical process control, SPC) y se simularon intervenciones para devolverlo al estado llamado en control.

    This study had the aim to verify the necessities of training and improvement of the 4th Regional Coordination in Health of Rio Grande do Sul State family health teams. The data collection was carried out through the application of questionnaires with objective questions, composed by two parts: field and competence nucleus. For data analyses, Normality, Chi-Square and G tests were used as statistical procedures for Easy and Difficult attributions indicated by the professionals. Professionals have shown less difficulty with generic attributions, related with basic methods and techniques of each health area. However, they have revealed a lot of difficulties with attributions relating to the search of new partners in health inside communities, stimulation of the people participation in the discussion of health rights, and completion of the SIA/SIAB forms, and others. Even after 12 years of the foundation of the Family Health Program (PSF), several difficulties are still observed concerning the way to work with this new health strategy in Brazil. Proposals are made for the complete understanding and improvement of the PSF strategy.

    We estimated genetic gains for popcorn varieties using selection indexes in a fourth cycle of intrapopulation recurrent selection developed in the campus of the Universidade Estadual do Norte Fluminense. Two hundred full-sib families were obtained from the popcorn population UNB-2U of the third recurrent selection cycle. The progenies were evaluated in a randomized block design with two replications at sites in two different environments: the Colégio Estadual Agrícola Antônio Sarlo, in Campos dos Goytacazes, and the Empresa de Pesquisa Agropecuária do Estado do Rio de Janeiro (PESAGRO-RIO), in Itaocara, both in the State of Rio de Janeiro. There were significant differences between families within sets in all traits, indicating genetic variability that could be exploited in future cycles. Thirty full-sib families were selected to continue the program. The selection indexes used to predict the gains were those of Mulamba and Mock, Smith and Hazel. The best results were obtained with the Mulamba and Mock index, which allowed the prediction of negative gains for the traits number of diseased ears and ears attacked by pests, number of broken plants and lodging, as well as ears with poor husk cover. It also provided higher gains for popping expansion and grain yield than with the other indexes, giving values of 10.55 and 8.50%, respectively, based on tentatively assigned random weights.

    BACKGROUND The cutaneous mycoses, mainly caused by dermatophyte fungi, are among the most common fungal infections worldwide. It is estimated that 10% to 15% of the population will be infected by a dermatophyte at some point in their lives, thus making this a group of diseases with great public health importance. OBJECTIVE To analyze the clinical, epidemiological, and therapeutic profile of dermatophytosis in patients enrolled at the Dermatology service of Universidade do Estado do Pará, Brazil, from July 2010 to September 2012. METHOD A total of 145 medical records of patients diagnosed with dermatophytosis were surveyed. Data were collected and subsequently recorded according to a protocol developed by the researchers. This protocol consisted of information regarding epidemiological and clinical aspects of the disease and the therapy employed. RESULTS The main clinical form of dermatophyte infection was onychomycosis, followed by tinea corporis, tinea pedis, and tinea capitis. Furthermore, the female population and the age group of 51 to 60 years were the most affected. Regarding therapy, there was a preference for treatments that combine topical and systemic drugs, and the most widely used drugs were fluconazole (systemic) and ciclopirox olamine (topical). CONCLUSION This study showed the importance of recurrent analysis of the epidemiological profile of dermatophytosis to enable correct therapeutic and preventive management of these conditions, which have significant clinical consequences, with chronic, difficult-totreat lesions that can decrease patient quality of life and cause disfigurement.
