    1997-02-01

    Magda Mateus Cardenas, trained as an anthropologist, is currently director of Centro Amauta, a feminist organization in Peru that addresses issues of gender, class, and culture. In this interview, Mateus Cardenas describes her long involvement with development organizations and grass-roots campaigns to improve women's status. She notes that, although many organizations have adopted a gender perspective, few comprehend its highly political, transformational aspects. Women's rights tend to be viewed by development agencies as just one more factor to be incorporated into development projects rather than as a perspective that changes views of development itself. A genuine gender perspective entails changes in the organizational, social, and political aspects of the themes of autonomy and empowerment, with adaptations of content and methods to local conditions. A precondition to women's emancipation is access to and control of financial and economic resources. This, in turn, requires training in technical skills and access to the marketplace on more competitive terms.

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

    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

    The orchid-bee faunas (Hymenoptera: Apidae: Euglossina) of the three largest forest remnants in the "Centro de Endemismo Pernambuco", northeastern Brazil, namely Estação Ecológica de Murici (ESEC Murici), RPPN Frei Caneca, and a forest preserve belonging to Usina Serra Grande, in the states of Alagoas and Pernambuco, were surveyed using seventeen different scents as baits to attract orchid-bee males. Eight sites were established in the three preserves, where samplings were carried out using two protocols: insect netting and bait trapping. We collected 3,479 orchid-bee males belonging to 29 species during 160 hours in early October, 2012. Seven species were collected in the "Centro de Endemismo Pernambuco" for the first time. Richness proved to be one of the highest of the entire Atlantic Forest domain, and diversity in some sites, especially at ESEC Murici, revealed to be one of the highest in the Neotropics. Eulaema felipei Nemésio, 2010, a species previously recorded only at ESEC Murici, was found in no other preserve in the region and its conservation status is discussed.

    We report the development and the construction of an Interface to Control a robotized Astronomical Observatory (ICOA), which allows to control the operation of an observatory based on a Meade LX200 telescope. The interface operates together with a computer to control and supervise all the local variables of the observatory, and can take the control of it in risky situations. It serves as a link among the control computer and all the necessary devices for the astronomical observation such as the telescope, the dome, the weather station, the CCD camera, the calibration devices and the security devices. The computer receives orders from an operator who can be or not at the site of observation. The goal of this robotized observatory is the operation in a secure, autonomous and unattended way, with the purpose of to be used remotely by the students of the "Facultad de Ciencias Exactas, Físicas y Naturales" of the UNSJ.

    Advanced disease is a risk factor for eye loss in patients with retinoblastoma (RB). We still record critical rates of enucleation, especially for unilateral RB due to advanced stages of disease at diagnosis. This retrospective study of 223 RB patient records referred to treatment at Centro Infantil Boldrini, Brazil, between 1978 and 2008, showed that 176 patients (79%) presented intraocular tumors while 47 (21%) already had extraocular involvement. At the time of diagnosis, the age of patients was 26.2 months in the group that had enucleated eyes and 13.7 months in the group that preserved both eyes. Under a multiple logistic regression model, familial history (OR = 0.195; p = .01) and age at diagnosis in months (OR = 1.047; p = .04) were significantly correlated with enucleation. Strategies to early detect RB must be changed in order to offer better chances of ocular preservation with visual function. Authors propose a systematic referral of all children to the ophthalmologist for an indirect ophthalmoscopy once a year in the first two years of life, as a measure to be adopted by all pediatricians in daily routine to early detect the tumor.

    Data on occupational diseases of seafarers and of causes of death during their career are sparse. The causes of deaths on board ships assisted by Centro Internazionale Radio Medico (CIRM), the Italian Telemedical Maritime Assistance Service (TMAS) were reviewed by examining 29,146 files of patients treated from 1986 to 2010. In the 25 years, 383 deaths occurred (1.31%). Diseases of the circulation were the most frequent, followed by external causes such as accidents and violence, infectious and parasitic diseases, alcohol and drug addiction, respiratory system diseases. Cardiovascular and external causes were the principal causes of deaths among seafarers. This investigation is the first study on the causes of death on board ships obtained from data of a maritime telemedical centre, that has assisted seafarers when they were alive or immediately after their death. The fact that diseases of the circulatory system are the first cause of death of sailing seafarers deserves specific initiatives. They should include campaigns for adequate lifestyles and the availability on ships of medical devices useful for diagnostic purposes, resuscitation as well as for verification of death.

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

    This paper explains the procedure used in the design of a heliostat to be installed at the headquarters of the Centro de Investigaciones de Astronomía, located in the city of Mérida, Venezuela. The heliostat will be used mainly for educational and public outreach programs, so the design specifications did not require compensation for rotation of the Sun's image at the focal point. The engineering computational tools CAD-CAE were used in order to allow a seamless interaction between the two disciplines involved, Mechanical Engineering and Astronomy. It has also been taken into consideration, as a starting requirement, that all materials be easily available and that all parts, excluding the optics, could be manufactured with the equipment available at the CIDA workshop. These considerations were intended to reduce the cost of the device and to increase the feasibility of construction with limited technological facilities and financial resources. The results obtained by means of the computing tools used were validated through comparison against the analytical calculations. As a result, a robust but low cost heliostat was designed which in the near future will be used to project the Sun's image on a screen for public viewing and student research projects.

    RIASSUNTO. Scopo. Nella riabilitazione psichiatrica il piano di trattamento individuale può essere formulato a partire da strumenti che offrano una valutazione multidimensionale del paziente. Il lavoro si propone di analizzare il rapporto tra gravosità (distress degli operatori) e stile di recupero (integration e sealing over) dalla patologia psicotica. Ipotizzando che esso influenzi il carico gestionale, lo studio si pone l'ulteriore obiettivo di acquisire maggiori elementi che indirizzino la formulazione di piani terapeutico-riabilitativi più efficaci. Metodi. Lo studio è stato condotto presso un centro diurno psichiatrico, struttura semi-residenziale dei servizi psichiatrici del Sistema Sanitario Nazionale in Italia. 45 pazienti reclutati sono stati valutati mediante la Neuropsychiatric Inventory (NPI - versione italiana) e la Integration/Sealing Over Scale (ISOS - versione italiana), nell'arco di tre mesi (marzo-giugno 2014). Risultati. Nel campione esaminato è emerso che la disinibizione, l'irritabilità e l'apatia sono i sintomi che provocano maggiore distress negli operatori, in senso assoluto. Inoltre, i risultati indicano che depressione e ansia recano un grado maggiore di distress nei pazienti sealer. Discussione e conclusione. Gli aspetti della disinibizione, dell'irritabilità e dell'apatia sono risultati più gravosi per gli operatori in quanto richiedono maggiore coinvolgimento nella relazione terapeutica. Sintomi ansiosi e depressivi risultano più gravosi nel gruppo dei sealer, segnalando minore tenuta della negazione della psicosi. I dati osservati sembrano provare che conoscere, differenziare e approfondire i diversi aspetti dello stile di recupero di ciascun paziente consente di stimare l'impegno gestionale fin dalla presa in carico e di ridurre il distress e il rischio di burnout degli operatori.

  19. Maintenance of blood flow rate on dialysis with self-centering CentrosFLO catheter: A multicenter prospective study.

    PubMed

    Agarwal, Anil K; Ash, Stephen R

    2016-10-01

    Introduction Chronic central venous catheters (CVC) for dialysis lose patency and deliver lower blood flow over time, often due to fibrous sheathing that covers the lumen tips. The CentrosFLO central venous catheter has a shape that directs the arterial and venous tips away from the walls of the vena cava and right atrium, making sheathing of the tips less likely. Methods A prospective, multicenter, single arm, non-controlled, observational study was conducted at eight sites in the United States. All consenting dialysis patients receiving CentrosFLO catheters through the right or left internal jugular veins were accepted in the study, as long as the catheter was expected to be used for 45 days and was not an over-the-wire replacement for a previous CVC. Data were automatically collected on initial and average dialysis blood flow rate and initial arterial and venous pressures, for up to 26 weeks of dialysis therapy. Findings 75 patients were enrolled. Kaplan-Meier analysis indicated that 87% of patients maintained blood flow rate over 300 mL/min throughout 26 weeks of follow-up. There was no decline in average dialysis blood flow rate and no significant change in hydraulic resistance of the arterial or venous lumens of the catheters during the study. Discussion The CentrosFLO catheter demonstrates long term patency with good flow rates on dialysis, which, by comparison with previous studies, shows a clinically significant improvement in blood flow rate vs. other catheters. Stable hydraulic resistance of the catheter lumens showed no evidence of tip encroachment by fibrous sheaths.

    Antecedentes y Objetivo: En México, el 64% de los pacientes hospitalizados sufren de desnutrición hospitalaria y hasta un 100% en adultos mayores, se han estudiado las causas, entre ellas se destacan: la sub-alimentación, el tiempo de hospitalización, el catabolismo presente en diversas patologías, falta de interés o tiempo del personal que labora en los hospitales entre otras. El objetivo del presente trabajo fue obtener la prevalencia de sub-alimentación en los pacientes hospitalizados con soporte enteral, en el Centro Médico “Lic. Adolfo López Mateos” (CMLALM) durante el periodo Agosto – Octubre 2014. Metodología: Se diseñó un estudio observacional, transversal, descriptivo; con una población de 52 pacientes con soporte enteral en el que se analizó la prevalencia de pacientes con sub-alimentación a partir de la ministración de la dieta enteral y la prescripción nutricional calórica establecida, durante el periodo de Agosto – Octubre 2014. Resultados: Se realizaron medidas de tendencia central para obtener el porcentaje de pacientes con sub-alimentación calórica. La prevalencia de pacientes con sub-alimentación fue del 71%, con mayor predominio el sexo masculino (70%) y en un rango de edad entre 51 años y 61 años (43%). El servicio médico de hospitalización donde se encontró la mayor prevalencia de pacientes con sub-alimentación fue medicina interna afectando a 14 pacientes (38%), seguido de neurocirugía con 7 pacientes (19%) y unidad de cuidados intensivos (UCI) con 7 pacientes (19%); siendo el turno nocturno donde se presentó en mayor predominio la sub-alimentación. Conclusiones: La sub-alimentación afectó a 37 pacientes con soporte enteral los cuales representan el 71% de la población estudiada, esta cifra coincide con otros estudios similares. La causa principal de la sub-alimentación fue el incumplimiento en la ministración de la dieta enteral.

    Benign childhood epilepsy with centro-temporal spikes (BCECTS) is a unique form of non-lesional age-dependent epilepsy with rare seizures, focal electroencepalographic abnormalities affecting the same well delineated cortical region in most patients, and frequent mild to moderate cognitive dysfunctions. In this condition, it is hypothesized that interictal electroencepalographic discharges might interfere with local brain maturation, resulting in altered cognition. Diffusion tensor imaging allows testing of this hypothesis by investigating the white matter microstructure, and has previously proved sensitive to epilepsy-related alterations of fractional anisotropy and diffusivity. However, no diffusion tensor imaging study has yet been performed with a focus on BCECTS. We investigated 25 children suffering from BCECTS and 25 age-matched control subjects using diffusion tensor imaging, 3D-T1 magnetic resonance imaging, and a battery of neuropsychological tests including Conner's scale and Wechsler Intelligence Scale for Children (fourth revision). Electroencephalography was also performed in all patients within 2 months of the magnetic resonance imaging assessment. Parametric maps of fractional anisotropy, mean-, radial-, and axial diffusivity were extracted from diffusion tensor imaging data. Patients were compared with control subjects using voxel-based statistics and family-wise error correction for multiple comparisons. Each patient was also compared to control subjects. Fractional anisotropy and diffusivity images were correlated to neuropsychological and clinical variables. Group analysis showed significantly reduced fractional anisotropy and increased diffusivity in patients compared with control subjects, predominantly over the left pre- and postcentral gyri and ipsilateral to the electroencephalographic focus. At the individual level, regions of significant differences were observed in 10 patients (40%) for anisotropy (eight reduced fractional anisotropy

    Benign Epilepsy with Centro-Temporal Spikes (BECTS) is a common childhood epilepsy associated with deficits in several neurocognitive domains. Neurophysiological studies in BECTS often focus on centro-temporal spikes, but these correlate poorly with morphology and cognitive impairments. To better understand the neural profile of BECTS, we studied background brain oscillations, thought to be integrally involved in neural network communication, in sensorimotor areas. We used independent component analysis of temporally correlated sources on magnetoencephalography recordings to assess sensorimotor resting-state network activity in BECTS patients and typically developing controls. We also investigated the variability of oscillatory characteristics within focal primary motor cortex (M1), localized with a separate finger abduction task. We hypothesized that background oscillations would differ between patients and controls in the sensorimotor network but not elsewhere, especially in the beta band (13-30 Hz) because of its role in network communication and motor processing. The results support our hypothesis: in the sensorimotor network, patients had a greater variability in oscillatory amplitude compared to controls, whereas there was no difference in the visual network. Network measures did not correlate with age. The coefficient of variation of resting M1 peak frequency correlated negatively with age in the beta band only, and was greater than average for a number of patients. Our results point toward a "disorganized" functional sensorimotor network in BECTS, supporting a neurodevelopmental delay in sensorimotor cortex. Our findings further suggest that investigating the variability of oscillatory peak frequency may be a useful tool to investigate deficits of disorganization in neurodevelopmental disorders.

    The City of El Centro was awarded a contract in late 1978 to cost share the development of a low to moderate temperature geothermal resource in the City. The resource would be utilized to heat, cool and provide hot water to the nearby Community Center. In December 1981, Thermal 1 (injector) was drilled to 3970 feet. In January 1982, Thermal 2 (producer) was drilled to 8510 feet. Before testing began, fill migrated into both wells. Both wells were cleaned out. A pump was installed in the producer, but migration of fill again into the injector precluded injection of produced fluid. A short term production test was undertaken and results analyzed. Based upon the analysis, DOE decided that the well was not useful for commercial production due to a low flow rate, the potential problems of continued sanding and gasing, and the requirement to lower the pump setting depth and the associated costs of pumping. There was no commercial user found to take over the wells. Therefore, the wells were plugged and abandoned. The site was restored to its original condition.

    An investigation was conducted at the Naval Air Facility located in El Centro (NAFEC), to determine the vertical and horizontal extent of hydrocarbon contamination at the facilities fuel farm. The fuel products are the result of tank and pipeline leakage, past tank cleaning, and past disposal of fuel dispensing and filter cleaning practices. Subsurface soil and groundwater data was collected via soil borings, monitoring wells, and CPT probes. Soil, groundwater, and analytical data were integrated using the LYNX geoscience modeling system (GMS). Interactive sessions with the data visualizer helped guide the modeling and identify data gaps. Modeling results indicate a continuous surface confining clay layer to a depth of about 12 to 15 ft. Groundwater is confined beneath this clay layer and monitoring wells indicate about 3 to 5 ft of artesian head. Hydrocarbon contamination is concentrated within this clay layer from about 5 to 12 ft below the ground surface. Residual fuel products located in the groundwater are attributed to slow leakage through the confirming clay layer. LYNX was also used to compute volumes of contaminated soil to aid in remediation cost analysis. Preliminary figures indicate about 60,000 yards[sup 3] of contaminated soil. Since the contamination is primarily confined to relatively impermeable clayey soils, site remediation will likely be ex-situ land farming.

    More than 20 hadrontherapy centres are active in the world and about 40,000 patients have been treated, almost 4000 with ions. Physical selectivity and high relative biologic efficiency (RBE) represent the rationale for using ions in the treatment of tumours. The clinical results are very promising and justify the construction of new centres. We present the main characteristics of CNAO (Centro Nazionale Adroterapia Oncologica) and its possible integration in a nationwide network. The Italian project started in 1991 thanks to the activity of the TERA Foundation and was financed by the Italian Government in 2002. The CNAO will be built in Pavia to start clinical activity in 2007. The equipment will include a synchrotron and 3 treatment rooms mainly devoted to carbon ions but able to deliver also protons. The Centre should be able to deliver up to 20,000 fractions / year. The realization of CNAO is part of a more ambitious project to set up an integrated national network. The need of hadrontherapy centres is defined by epidemiological studies based on Italian tumour registries showing that almost 900 patients can be electively treated with protontherapy and about 10,000 could be included in clinical trials. Considering that ions could be used for radioresistant tumours that affect about 25,000 new patients/year, we estimate that 10-15%, i.e. 3000-4000 patients would benefit from ion therapy. The realization of a nationwide network possibly linked to a larger European network will be very helpful in making available hadrontherapy for a large part of the population.

    Introdução: O vírus do papiloma humano é responsável pela infeção sexualmente transmissível mais comum, podendo manifestar--se por um conjunto amplo de doenças, nomeadamente condilomas anogenitais, papilomatose laríngea recorrente, e neoplasias da região anogenital, colo do útero e orofaringe. Estima-se que os condilomas anogenitais afetem 1% da população sexualmente ativa, causados em cerca de 90% pelos genótipos 6 e 11. Material e Métodos: Identificámos os doentes com primeiro diagnóstico de condilomas anogenitais da consulta de doenças sexualmente transmissíveis do Centro de Saúde da Lapa, entre janeiro de 2008 e dezembro de 2014, e caracterizámos os doentes por sexo, orientação sexual, idade, localização das lesões, e número de parceiros nos últimos seis meses. Resultados: Foram identificados 902 indivíduos com primeiro diagnóstico de condilomas anogenitais. Observámos uma diminuição significativa de novos casos nas mulheres com < 19 anos (r = -0,848; p = 0,016), e uma diminuição sem significado estatístico nos homens com < 19 anos e nas mulheres entre os 20 - 24 anos. Discussão: Em outubro de 2008, a vacina quadrivalente (genótipos 6, 11, 16, 18) foi introduzida no plano nacional de vacinação de Portugal, abrangendo as adolescentes com 13 anos, com um catch-up para as de 17 anos. A diminuição de primeiros diagnósticos de condilomas anogenitais nas mulheres, deve-se provavelmente à sua vacinação antes de iniciarem a vida sexual. Conclusão: Este estudo reforça a import'ncia do programa nacional de vacinação para o vírus do papiloma humano.

    The recently established CAT (Centro di Allerta Tsunami) at Istituto Nazionale di Geofisica e Vulcanologia (INGV) will be part of the Italian National Tsunami Warning Center (It-NTWC) and it is a candidate Tsunami Watch Provider (cTWP) for the Mediterranean Sea in the framework of the Tsunami Early Warning and Mitigation System in the North-eastern Atlantic, the Mediterranean and connected seas (NEAMTWS). It-NTWC is a partnership of three Italian institutions: INGV, the Italian Department of Civil Protection (Dipartimento di Protezione Civile, DPC) and the Institute for Environmental Protection and Research (Istituto Superiore per la Protezione e la Ricerca Ambientale, ISPRA) which provides the sea-level data of the Italian mareographic network (Rete Mareografica Nazionale, RMN) in quasi-real-time. CAT is the operational part of the It-NTWC based at the INGV 24/7 seismic monitoring centre in Rome. CAT will be committed to deliver tsunami warning messages to DPC and, when it will enter its operational cTWP phase, to any IOC/UNESCO member state that will subscribe for the service. The current implementation of CAT is based on the NEAMTWS Decision Matrix (DM). Earthquake parameters are determined automatically by the Early-Est (EE) software, and used as an input to DM and tsunami travel times calculation to provide warning messages, including earthquake parameters, plus level of alert and estimated tsunami arrival time at pre-defined forecast points along threatened coasts. Basing on updated automatic EE solutions, seismologist's revision, and sea-level readings subsequent messages can be delivered until warning status ends. The use of the DM allows a rapid implementation of a tsunami warning system, but it does not consider some important features to better characterize a tsunami forecast, such as the earthquake's focal mechanism, the directivity of tsunami propagation and the morphology of the coast. More sophisticated procedures are currently under development: a

    The Serra do Moradal-Fajão syncline is a major NNW-SSE Variscan structure developed in the SW sector of the Centro-Iberian Zone, one of the main geodynamical structures of the Iberian Variscides. This tight syncline with a 1.5 km wavelength, could be followed for more than 80 km and represents one of the most important regional structures. Its complex structure has been possible to characterize, not only due to excellent outcrop condition (mostly induced by the competent behaviour of the Lower Ordovician Armorican Quartzite Formation), but also to the detailed lithostratigraphic control of the Ordovician-Silurian lithologies. These units are present in a homogeneous regional distribution, unconformably overlain the Cambrian Beiras Group. Concerning the Variscan structures, their geometry and kinematics show that they could be ascribed to progressive deformation induced by the first and main D1 tectonic event. During this event, a complex NNW-SSE aggregation of fold and thrust arrays have been developed. At the macroscale, this pattern is mainly characterized by the Serra de Moradal-Fajão syncline. Both limbs of this major D1 Variscan fold, which present a slightly ENE facing, have been disrupted by convergent thrust systems, leading to the superposition of the Cambrian Beiras metasediments on top of the Ordovician-Silurian succession. Concerning its SW limb, a major single overthrust has been developed, the Vilar Barroco-Fajão one, although in some very localized sectors, some minor thrusts could be emphasized; as they present a ENE facing, they are interpreted as duplex style forethrusts in relation to the main overthrust. Regarding the NE limb, a different behaviour is found. Indeed, in this sector, an imbricated thrust system has been mapped; due to their WSW facing it should be considered as backthrusts. Concerning the temporal relations between the previously described structures, although in some rare cases backthrusts cut forethrusts, the scarcity of

    Here we report the first demonstration for centro-apical self-organization of organic semiconductors in a line-printed organic semiconductor: polymer blend. Key feature of this work is that organic semiconductor molecules were vertically segregated on top of the polymer phase and simultaneously crystallized at the center of the printed line pattern after solvent evaporation without an additive process. The thickness and width of the centro-apically segregated organic semiconductor crystalline stripe in the printed blend pattern were controlled by varying the relative content of the organic semiconductors, printing speed, and solution concentrations. The centro-apical self-organization of organic semiconductor molecules in a printed polymer blend may be attributed to the combination of an energetically favorable vertical phase-separation and hydrodynamic fluids inside the droplet during solvent evaporation. Finally, a centro-apically phase-separated bilayer structure of organic semiconductor: polymer blend was successfully demonstrated as a facile method to form the semiconductor and dielectric layer for OFETs in one- step.

    In the past few years several gene mutations have been identified as causative of the most frequent neurodegenerative dementias (Alzheimer disease and frontotemporal dementia). These advances, along with the complex phenotype-genotype relationships and the costs associated with genetic testing, have often made it difficult for clinicians to decide with regard to a rational plan for the investigation of the genetic etiology of the degenerative dementias. The Centro Hospitalar São João Neurogenetics Group, a multidisciplinary team of Neurologists and Geneticists with special interest in neurogenetic disorders, devised consensus recommendations for the investigation of the genetic etiology of Alzheimer disease and frontotemporal dementia in clinical practice, based on international consensus documents (currently containing partly outdated information) and published scientific evidence on this topic. Alzheimer disease may be caused by mutations in PSEN1, PSEN2 and APP. APOE genotyping is not recommended for the diagnostic or genetic counseling purposes in Alzheimer disease. Frontotemporal dementia may be caused by mutations in several genes such as c9orf72, PGRN, MAPT, TBK1, VCP, SQSTM1, and UBQLN2. This paper pragmatically approaches the process of genetic diagnosis in Alzheimer disease and frontotemporal dementia, with specific recommendations for both disorders.

    The main aim of this work is the development and testing of a method for the astrometric measurement of photographic plates using a CCD camera as a digitizing device. This method is useful for the measurement of first epoch positions from more than 3000 plates in the vault of the Observatorio Astronómico de Córdoba, most of them more than 80 years old, in order to determine accurate proper motions. The developed method is applied to a Carte du Ciel plate in order to obtain positions of 4172 stars at epoch 1917.13 with errors about 0.20arcsec. By combining these positions with USNO-B1.0 and UCAC2 proper motions with accuracies around 2mas/year were determined for 4061 stars in a square field 2deg sided contaning the open clustes NGC 2587. Projected stellar density is studied in order to locate the cluster. Membership probabilities were determined from the proper motions by means of a non-parametric method and Monte Carlo simulations. 31 probable members were identified within 15arcmin around the projected overdensity asumed as the cluster, 22 of them within 10arcmin.

    We present the first determination of proper motions on Carte du Ciel plates from Córdoba Observatory as source of first epoch positions. The plate selected for this work was the one numbered 6448 that corresponds to a field close to the galactic center, containing the open cluster NGC 2587. In order to measure the 2° photographic plate a mosaic of 8×8 CCD images with 50% overlap was taken with a 1024×1024 square pixels camera, each frame covering an area of approximately 30'. The detection and centering of stellar images was performed with the software SExtactor and our own software that identifies the triple exposures. The reduction to celestial coordinates was performed by means of the block-adjustment technique, using Tycho-2 as reference catalog. The errors of first epoch positions were found between 0.20" and 0.25". Second epoch positions provided by the UCAC2 catalog with an accuracy of 0.02" to 0.07". From the errors of positions it was estimated that the accuracy of the derived proper motions is approximately 3mas/yr for stars brighter than 12.5mag and 4mas/yr for the fainter ones that can reach up to 15mag.

    Preliminary proper motions were determined from the combination mainly of first epoch positions from Carte du Ciel Plates from Córdoba Observatory and recent observations performed with the CCD Meridian Circle of the Intitute of Astronomy and Geophysics, São Paulo University (Brazil). Positions from USNO- A2.0 and AC2000 were taken into account for some stars. The fields correspond to two low-extinction windows in the galactic bulge. The photographic plates were digitized with MAMA (Machine Automatique á Mesurer pour l'Astronomie) at the Paris Observatory. Software SExtractor was employed for the detection of `objects' in the digital images. Specific software was developed for the rejection of spurious detections taking advantage of the geometry of CdC triple exposures and for the reduction of positions using ACT Reference Catalog. The observations with the IAG-USP meridian circle are part of an astro-photometric study of the galactic bulge. Preliminary proper motions for 135 stars were determined within window BE and 34 in window LR. They are nearly all the stars detected over those areas on the plates. Median errors of these preliminary proper motions are about 4 mas/yr, being below 6 mas/yr in all cases.

    Land plants rely mainly on gravitropism and phototropism to control their posture and spatial orientation. In natural conditions, these two major tropisms act concurrently to create a photogravitropic equilibrium in the responsive organ. Recently, a parsimonious model was developed that accurately predicted the complete gravitropic and proprioceptive control over the movement of different organs in different species in response to gravitational stimuli. Here we show that the framework of this unifying graviproprioceptive model can be readily extended to include phototropism. The interaction between gravitropism and phototropism results in an alignment of the apical part of the organ toward a photogravitropic set-point angle. This angle is determined by a combination of the two directional stimuli, gravity and light, weighted by the ratio between the gravi- and photo-sensitivities of the plant organ. In the model, two dimensionless numbers, the graviproprioceptive number B and the photograviceptive number M, control the dynamics and the shapes of the movement. The extended model agrees well with two sets of detailed quantitative data on photogravitropic equilibrium in oat coleoptiles. It is demonstrated that the influence of light intensity I can be included in the model in a power-law-dependent relationship M(I). The numbers B and M and the related photograviceptive number D are all quantitative genetic traits that can be measured in a straightforward manner, opening the way to the phenotyping of molecular and mechanical aspects of shoot tropism.

    Introduction. Our objective was to determine the trend of the antimicrobial susceptibility of the most common bacterial pathogens isolated in La Mancha Centro Hospital (MCH) between 2010-2012. Material and methods. Isolates of Staphylococcus aureus, Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa from patients admitted to MCH were studied. These data and their antibiotic susceptibility were obtained from the database OBSERVA (BioMérieux). Results. The percentages of susceptibility for S. aureus were: 50% methicillin-resistant-S. aureus (MRSA) (higher co-resistance to erythromycin and levofloxacin), 46% erythromycin, 73% clindamycin, 45% levofloxacin, 99% rifampin and 100% cotrimoxazole, glycopeptides, linezolid and daptomycin. Increased resistance in ICU was observed (63% MRSA), with 50% of S. aureus (susceptible and methicillin-resistant strains) with vancomycin MIC values ≥ 0.5 mg/L. E. coli susceptibility: 62% amoxicillin-clavulanate, 55% ciprofloxacin, 60% cotrimoxazole, 84% gentamicin and 95% fosfomycin. K. pneumoniae susceptibility: 74% amoxicillin-clavulanate, 71% ciprofloxacin, 78% cotrimoxazole, 94% gentamicin and 87% fosfomycin. The percentage of BLEE strains was 17% and 21% for E. coli and K. pneumoniae, respectively, without detection of resistance to carbapenems. P. aeruginosa susceptibility: 80% ceftazidime and carbapenems, 63% ciprofloxacin and higher than 90% aminoglycosides. A decreasing trend of susceptibility to ceftazidime and carbapenems was observed in ICU and increasing trend to ciprofloxacin. Conclusions. Resistance percentages were higher in ICU than in the rest of the hospital, highlighting 63% of MRSA strains. Our percentage of BLEE and MRSA strains were higher than the Spanish media. Rifampicin and cotrimoxazole maintain good susceptibility to S. aureus, fosfomycin and aminoglycosides to Enterobacteriaceae and carbapenems to P. aeruginosa.

    The Centro Nazionale Terremoti (CNT - National Earthquake Center), departement of Istituto Nazionale di Geofisica e Vulcanologia (INGV), has designed and setup a rapid response emergency structure to face the occurrence of strong earthquakes. This structure is composed by a real time satellite telemetered temporary seismic network (see Abruzzese et al., 2009 Fall AGU) used to improve the hypocentral locations of the INGV National Seismic Network, a stand alone temporary seismic network whose goal is primarily the high dynamic/high resolution data acquisition in the epicentral area and a mobile operational center, the COES (Centro Operativo Emergenza Sismica, Seismological Emergency Operational Center). The COES structure is a sort of mobile office equipped with satellite internet communication that can be rapidly installed in the disaster area to support all the INGV staff operative needs and to cooperate with the Civil Protection department (DPC) aggregating all the scientific information available on the seismic sequence and providing updated information to Civil Protection for the decision making stage during the emergency. The structure is equipped with a heavy load trolley that carries a 6x6 inflatable tent, a satellite router, an UPS, computers, monitors and furniture. The facility can be installed in a couple of hours in the epicentral area and provides a full featured office with dedicated internet connection and VPN access to the INGV data management center in Rome. Just after the April 6 2009 Mw 6.3 earthquake in L’Aquila (Central Italy) the COES has been installed upon request of the Italian Civil Protection (DPC) in the DICOMAC (Directorate of Command and Control - which is the central structure of the DPC that coordinates the emergency activities in the areas affected by the earthquake) located in the Guardia di Finanza headquarters in Coppito nearby L'Aquila (the same location that hosted the G8 meeting).

    SUMMARY The frequency of anti-Toxocara spp. antibodies in individuals attended by the Centro de Salud Familiar in the coastal Niebla town, Chile, was related to the host and to environmental factors. IgG anti- Toxocara antibodies were detected with a commercial ELISA kit (SCIMEDX Corporation, USA). Samples with undetermined absorbance values were subjected to an additional ELISA standardized by the Instituto de Salud Pública, Chilean Health Ministry, a commercial ELISA (NOVATEC, Germany), and a commercial Western blot kit (LDBio Diagnostics, France). Hematological exams were performed using an automated blood counter and blood smears. Dog feces were collected from the ground along the main road in Niebla, including rural and urban locations. Ninety (25.4%) of the 355 examined individuals were positive by the ELISA test. The frequency of anti-Toxocara antibodies and the infection risk were significantly higher (p < 0.05) among those individuals ≥ 40 years old with respect to the 20-39 years old group, in individuals from rural locations, those who did not have a safe drinking water supply in the house or who presented blood eosinophilia. The proportion of positive samples of dog feces and the mean number of Toxocara canis eggs/g of feces in urban and rural areas were similar (p > 0.05). PMID:27680167

    Bridging the survival gap for children with cancer, between those (the great majority) in low and middle income countries (LMIC) and their economically advantaged counterparts, is a challenge that has been addressed by twinning institutions in high income countries with centers in LMIC. The long-established partnership between a Central American consortium--Asociación de Hemato-Oncología Pediátrica de Centro América (AHOPCA)--and institutions in Europe and North America provides a striking example of such a twinning program. The demonstrable success of this endeavor offers a model for improving the health outcomes of children with cancer worldwide. As this remarkable enterprise celebrates its 15th anniversary, it is appropriate to reflect on its origin, subsequent growth and development, and the lessons it provides for others embarking on or already engaged in similar journeys. Many challenges have been encountered and not all yet overcome. Commitment to the endeavor, collaboration in its achievements and determination to overcome obstacles collectively are the hallmarks that stamp AHOPCA as a particularly successful partnership in advancing pediatric oncology in the developing world.

    The Centers for High Cost Medication (Centros de Medicação de Alto Custo, CEDMAC), Health Department, São Paulo were instituted by project in partnership with the Clinical Hospital of the Faculty of Medicine, USP, sponsored by the Foundation for Research Support of the State of São Paulo (Fundação de Amparo à Pesquisa do Estado de São Paulo, FAPESP) aimed at the formation of a statewide network for comprehensive care of patients referred for use of immunobiological agents in rheumatological diseases. The CEDMAC of Hospital de Clínicas, Universidade Estadual de Campinas (HC-Unicamp), implemented by the Division of Rheumatology, Faculty of Medical Sciences, identified the need for standardization of the multidisciplinary team conducts, in face of the specificity of care conducts, verifying the importance of describing, in manual format, their operational and technical processes. The aim of this study is to present the methodology applied to the elaboration of the CEDMAC/HC-Unicamp Manual as an institutional tool, with the aim of offering the best assistance and administrative quality. In the methodology for preparing the manuals at HC-Unicamp since 2008, the premise was to obtain a document that is participatory, multidisciplinary, focused on work processes integrated with institutional rules, with objective and didactic descriptions, in a standardized format and with electronic dissemination. The CEDMAC/HC-Unicamp Manual was elaborated in 10 months, with involvement of the entire multidisciplinary team, with 19 chapters on work processes and techniques, in addition to those concerning the organizational structure and its annexes. Published in the electronic portal of HC Manuals in July 2012 as an e-Book (ISBN 978-85-63274-17-5), the manual has been a valuable instrument in guiding professionals in healthcare, teaching and research activities.

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

    Mexico's peasant sector is undergoing great change as a result of the insertion of capitalist relations into areas that were previously remote. The traditional peasant subsistence economy has been displaced, and peasants have been forced to adopt a series of new strategies for survival, entailing proletarianization or selling of labor. Women in the community of San Nicolas Zoyapetlayoca, in the municipio of Tepeaca, have lived in a situation of poverty and precariousness for some time. Most of the population historically depended on the neighboring haciendas for their livelihood. Women and children also worked there, mistreated and without social protection. The lands that were distributed after the Revolution are insufficient to support the community, and most families must look elsewhere for employment. Incomes are insufficient to cover all the necessities of education, health, nutrition, and other aspects of life. Most women are educated no farther than the primary level. They spend most of their time preparing food, carrying water, washing clothes, caring for their children, and in other domestic chores. Some women work for wages as laborers, factory workers, or domestics. Rural women are disadvantaged by poor working conditions, insufficient education, low levels of health and nutrition, limited participation in social and political life, poor housing and lack of services, and frequently by their own attitudes of traditionalism or fatalism.

    An abbreviated primer on the sociology of the family is presented. The work defines family, describes different types of family structure, outlines the family life cycle, and discusses the functioning of families. Human beings in all societies require membership in a family of some type for reproduction and socialization. One of the most basic human needs is for a mother who will feed, protect, and instruct her offspring. Families have always changed in response to societal changes. The functions of a family are devoted to two different sets of objectives, the internal ones of psychosocial protection of the members and the external ones of accommodation to and transmission of a culture. Families in all cultures provide their members with a sense of identity. Families must respond to internal and external changes and should be capable of transforming themselves to adjust to new circumstances without losing continuity. Family systems differentiate themselves to carry out their functions through their subsystems. Individuals and dyads such as maternal-child or husband-wife are the subsystems. The family life cycle entails a series of stages: courtship, marriage, the birth and growth of children, separation of the children, retirement, old age. Each stage has its own pitfalls and challenges. Each family has a hierarchy of status and power, although in some cases the proper hierarchies are inverted, and the children carry out functions that should be completed by the parents. A series of explicit and implicit, rigid and flexible rules guide the functioning of the family. Various roles are carried out, including parental, marital, and sibling roles, as well as roles of authority, administration, and messenger.

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

    El cúmulo abierto NGC 2516 (α = 7h 58m y δ = -60o 45') tiene una edad de, aproximadamente, 150 Myr. El análisis de este sistema es particularmente importante en el Hemisferio Sur debido a su abundancia de estrellas peculiares y muy estudiado aplicando técnicas fotométricas, pero muy poco analizado desde el punto de vista astrométrico. A partir de una placa obtenida en el Observatorio Astronómico de La Plata y observaciones más actuales, nos hemos abocado al estudio de los movimientos propios de este cúmulo con el fin de determinar la pertenencia al mismo de las estrellas del campo de dicho cúmulo. Luego de llevar a cabo la determinación de los movimientos propios de todas las estrellas a partir de las posiciones obtenidas de la placa existente en el Observatorio de La Plata de 1914 y leídas con la MAMA en París, las observaciones realizadas con el círculo meridiano de San Fernando que se encuentra en el Observatorio Félix Aguilar de San Juan y las posiciones existentes en los catálogos AC 2000, Tycho, USNO y UCAC, programamos el método de Vasilevsky y Sanders para determinar la pertenencia de las estrellas de la región al cúmulo en cuestión. En un paso posterior, se realizó una modificación al método anterior para la determinación de los miembros. En esta modificación se consideró la densidad de las estrellas del cúmulo y la densidad de estrellas de campo. Esto permitió evaluar la pertenencia, no sólo a partir del movimiento propio de las estrellas, sino también a partir de la posición de las mismas con respecto al centro del cúmulo. También se consideró la dependencia de los parámetros con la magnitud. Los resultados así obtenidos fueron comparados con otras investigaciones de movimientos propios de la región del cúmulo. El movimiento propio absoluto del cúmulo fue comparado con el obtenido a partir de los catálogos estelares. Se encontró que los resultados coincidían para estrellas brillantes (magnitud más brillante que

    Introduccion. El correo electronico puede facilitar la comunicacion entre niveles. Nuestros medicos de atencion primaria disponen del correo de la consulta monografica de cefaleas (CMC) desde noviembre de 2009, por lo que se pretende analizar la utilizacion del correo electronico durante cinco años. Pacientes y metodos. Recogimos prospectivamente datos de los correos enviados hasta octubre de 2014. Las preguntas se clasificaron en necesidad de derivacion a la CMC (grupo 1), evolucion de casos atendidos en la CMC (grupo 2), formacion en cefaleas (grupo 3) o tratamiento de la cefalea padecida por el propio medico de atencion primaria como paciente (grupo 4). Resultados. Analizamos 274 correos. Las consultas mensuales se han incrementado (de 1,5 al mes durante el primer año a 7,5 al mes durante el quinto). El 10,2% de los correos provenia de centros de salud rurales y el 89,8% de centros de salud urbanos. Se contestaron en 2 ± 2,8 dias (rango: 0-24 dias). En el grupo 1 se encuadraron 130 consultas (47,4%), y en 60 se recomendo (46,2%) la derivacion por via normal, en 47 (36,2%) la preferente y en 23 (17,6%) la no derivacion. En el grupo 2 se incluyeron 125 correos (45,7%), y en 80 no fue necesaria nueva cita o adelanto de la prevista (64%). Trece consultas (4,7%) se clasificaron en el grupo 3 y seis (2,2%) en el grupo 4. Conclusiones. Nuestros medicos de atencion primaria manejan cada vez mas el correo electronico de la CMC. Permite detectar pacientes en los que procede un adelanto de cita, bien primera visita o revision, o resolver cuestiones sin necesidad de derivacion. Es eficaz para la atencion del medico con cefalea y como herramienta de formacion continuada.

    Introdução/Objectivo: A monitorização do risco residual infeccioso pela transfusão, é importante pois permite avaliar a melhoria alcançada na segurança das dádivas de sangue e adoptar políticas adequadas de redução dos riscos. Este estudo calcula as estimativas da taxa de incidência e do risco residual infeccioso para as infecções pelo vírus da imunodeficiência humana (VIH), vírus da hepatite B (VHB) e vírus da hepatite C (VHC), entre 1999 e 2010. Os dados foram analisados em períodos de quatro anos (1999-2002, 2003-2006 e 2007-2010) e as estimativas foram comparadas com as obtidas previamente, para dádivas ocorridas entre 1991 e 1998.Material e Métodos: O estudo incluiu 209 640 colheitas de sangue, provenientes de 42 634 dadores regulares, voluntários e não remunerados. Para o cálculo do risco residual infeccioso, utilizamos o modelo matemático taxa de incidência-período de janela, descrito por Schreiber et al. Todas as dádivas foram rastreadas de acordo com a legislação portuguesa. Em Janeiro de 2001 foi implementado, em todas as dádivas de sangue, o teste de ácidos nucleicos em minipool, para o rastreio simultâneo de ácido ribonucleico (ARN) VIH-1 e VHC (Cobas Amplicor Ampliscreen-Roche©) o qual foi substituído, em Janeiro de 2007, pelo rastreio simultâneo de ácido desoxirribonucleico VHB e de ácido ribonucleico VHC e VIH-1/VIH-2, em minipool (Cobas TaqScreen MPX Test-Roche©).Resultados: O risco residual infeccioso de uma dádiva em período de janela é muito reduzido e tem diminuído ao longo dos anos. Após a implementação de teste de ácidos nucleicos em minipool para os três vírus, a probabilidade de colhermos uma dádiva infecciosa e não detectada pelos testes de rastreio foi de 1/1,67 milhões de dádivas para o vírus da imunodeficiência humana, de 1/3,33 milhões para o vírus da hepatite C e de 1/526 000 para o vírus da hepatite B.Conclusões: Durante os 12 anos em estudo verificamos uma diminuição do risco residual infeccioso de cinco vezes para o vírus da imunodeficiência humana e vírus da hepatite B, e de 32 vezes para o vírus da hepatite C. Se compararmos o período 1991-1998 com o último período do estudo, 2007-2010, ou seja, durante 20 anos, a diminuição é relevante, verificando-se uma diminuição do risco para vírus da imunodeficiência humana, vírus da hepatite B e vírus da hepatite C, na ordem de 19, seis e 54 vezes respectivamente.

    The C3P &. NASA International Workshop on Environment and Alternative Energy was held on November 15-18, 2011 at the European Space Agency (ESA)'s Research and Technology Centre (ESTEC) in Noordwijk, The Netherlands. The theme of the workshop was "Global Collaboration in Environmental and Alternative Energy Strategies". The workshop was held at ESTEC's conference center. More than 110 individuals from eleven countries attended the workshop. For the first time since the inception of NASA-C3P workshops, a full day was dedicated to a student session. Fifteen students from around the globe gave oral presentations along with poster displays relating to the latest technologies in environmental and alternative energy strategies. Judges from NASA, C3P and ESA awarded plaques to the top three students. In addition to the students, thirty eight U.S. and international subject matter experts presented on the following general environmental-related topics: (1) Hazardous materials management and substitution in support of space operations (2) Emerging renewable and alternative energy technologies (3) Sustainable development and redevelopment (4) Remediation technologies and strategies The workshop also included a panel discussion on the topic of the challenges of operating installations across borders. Throughout the workshop, attendees heard about the scope of environmental and energy challenges that industry and governments face. They heard about technologies for increasing energy efficiency and increasing use of renewable energy. They learned about ways companies and government agencies are using materials, processes, goods and services in a manner more respectful with the environment and in compliance with health and safety rules. The concept of partnerships and their inherent benefits was evidenced throughout the workshop. Partnering is a key aspect of sustainability because sustainable development is complicated. Through formal presentations and side discussions, attendees commented on the need for continued exploration of joint projects of mutual interest.

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

    CCD BVI Johnson-Cousins observations obtained for 1759 stars in 4'×4' regions around the unstudied southern stellar aggregates Ruprecht 103, 124, 129, 146 and 166 are presented. The objects are described as open clusters in the catalogues of star clusters and associations of Alter et al. (1970) and LyngÅ (1987), as well as, in the ESO/Uppsala Survey of the ESO (B) Atlas (Lauberts 1982). Our analysis shows that none of these objects are genuine open clusters, except perhaps Ruprecht 166, since no clear main sequences (MSs) or other meaningful features can be seen in the extracted (V,B-V) and (V,V-I) colour-magnitude diagrams (CMDs). The star sequences seen in the distinct CMDs, specially for Ruprecht 124 and 129, are apparently formed by the superimposition of MS field stars affected by varying amounts of interstellar absorption and/or placed at different distances from the Sun. The CMDs of Ruprecht 166 present a pronounced variation in the luminosity function along the apparent MS, a fact from which we can infer the notion of these stars had a different origin. Star counts carried out within and outside the cluster candidate fields not only support the results that the objects do not present a significant number density contrast with respect to the Galactic disk, but also show that they do not appear to be candidate late stages of star cluster dynamical evolution. Several other stellar aggregates included in open cluster catalogues have previously been disproved as genuine physical systems (see, e.g., Carraro & Patat 1995, MNRAS, 276, 563; Carraro 2000, A&A, 357, 145; Piatti & Clariá 2001, A&A, 370, 931). Thus, the present work implies the potential likelihood of other wrongly classified open clusters.

    El Salvador has 20 potentially active volcanoes, four of which have erupted in the last 100 years. Since San Vicente Volcano has had no historic eruptions, monitoring is not a high priority; especially given the current eruptive crisis at San Miguel Volcano. Though probability of eruptive hazards remains low at San Vicente, it is arguably one of the most hazardous volcanoes in the country due to rainfall-induced landslides and debris-flow risk. At least 250 deaths occurred in November 2009 from landslides and debris flows triggered by Hurricane Ida. This disaster caused the Universidad de El Salvador - Facultad Multidisciplinaria Paracentral (UES-FMP, San Vicente, El Salvador) to partner with governmental and nongovernmental organizations (including the U.S. Peace Corps, U.S. Fulbright Program, Korean International Cooperation Agency, Protección Civil and the Centro de Protección para Desastres (CEPRODE)) to focus its faculty and student research toward hazard monitoring and risk studies. Newly established monitoring efforts include: measurement of surface cracks and localized rainfall by Protección Civil and local residents using crude extensometers and rain gauges; installation of six weather stations that operate within the most at-risk municipalities; seismic refraction surveys to better characterize stratigraphy and seasonal water table changes; and most recently, a USAID/NSF-funded initiative partnered with the UES-FMP to monitor seasonal hydrologic conditions related to flooding and groundwater recharge. The information from these initiatives is now used to communicate current conditions and warnings through a network of two-way radios established by CEPRODE and Protección Civil. Representatives from the multi-institutional team also communicate the data to authorities who make better-informed decisions regarding warnings and evacuations, as well as determine suitable areas for population relocation in the event of a crisis. Data will eventually be used

    Introducción: los cambios fisiológicos propios del envejecimiento, junto con distintos procesos patológicos, predisponen a los ancianos a la aparición de complicaciones nutricionales, siendo el estado nutricional un factor pronóstico importante. El objetivo del estudio es conocer la prevalencia de desnutrición en los mayores de 65 años en nuestro centro, tanto al ingreso como al alta. Métodos: realizamos un estudio transversal, observacional. Para ello evaluamos 174 pacientes mayores de 65 años que ingresaron de forma consecutiva, mediante la aplicación del Nutritional Risk Screening 2002 (NRS- 2002) y el Mini Nutritional Assessment Short Form (MNA-SF) en las primeras 48 horas de ingreso. Los pacientes oncológicos también se evaluaron mediante la Valoración Global Subjetiva Generada por el Paciente (VGS-GP). Al alta se realizó de nuevo el NRS-2002. Resultados: el 29,31% de los pacientes estaban en situación de riesgo nutricional según los resultados del NRS-2002 al ingreso. Este porcentaje aumentaba hasta el 57,89% al alta. El MNA-SF objetivó alteración nutricional en el 70,35% (54,65% riesgo de desnutrición, 15,7% desnutrición). Según el NRS-2002 el 34,14% de los pacientes con cáncer presentaban riesgo nutricional; sin embargo, la VGS-GP mostraba deterioro nutricional en el 56,41% de los casos (46,15% desnutrición moderada y 10,26% desnutrición grave). Existen grupos de pacientes (los de mayor edad, los ingresados de forma urgente, los que presentan insuficiencia cardíaca) con mayor riesgo de deterioro nutricional durante el ingreso (p < 0,05). Conclusiones: el porcentaje de pacientes mayores de 65 años en riesgo nutricional en nuestro centro es muy alto, tanto al ingreso como al alta. Se hace necesario el cribado nutricional sistemático.

    Pioneering scientific information in underdeveloped areas poses several problems, such as (1) lack of understanding on the part of key functionaries as to the why, what, and when of information services; (2) lack of trained personnel to assume the responsibility for such services; (3) lack of economic resources; and (4) lack of information pertaining to available bibliographical sources in the particular area or region. The Bibliographic and Documentation Service of the Institute of Nutrition of Central America and Panama (INCAP) provides, in addition to the customary services, technical assistance for the organization or reorganization of biomedical libraries and makes INCAP library materials available to member countries, either by loan or photocopy. Although the program was designed for the member countries, INCAP tries to make its services available to other Latin American nations, Africa, and Asia, where similar nutritional problems are being studied.

    Objetivos: Los objetivos de este estudio fueron evaluar el estado nutricional e índice de resistencia insulínica mediante HOMA en una población de adolescentes, así como establecer correlaciones entre el estado nutricional de los sujetos, la existencia o no de resistencia a la acción insulínica y el riesgo de padecer hipertensión arterial. Muestra y metodología: Una población de 1001 adolescentes de entre 9 y 17 años de edad, pertenecientes a 18 centros educativos de las provincias de Granada y Almería. Se realizó una valoración completa del estado nutricional de los alumnos mediante antropometría. Para el estudio metabólico, se practicó una extracción sanguínea mediante punción venosa a cada alumno, analizando glucosa basal, insulina basal, índice HOMAIR. Además, se valoró hemoglobina glicosilada (HBA1c), niveles séricos de lipoproteína (a) y ácidos grasos de cadena larga (NEFA). Para el cálculo del índice de resistencia a la insulina, se utilizó el modelo matemático propuesto por Matthews (Homeostasis Model Assessment - HOMAIR), aplicando la fórmula HOMAIR = (insulina x glucosa)/22,5. Resultados: La valoración del estado nutricional reveló un progresivo incremento en los valores de las variables antropométricas a medida que el estado nutricional de los sujetos empeoraba, describiéndose una prevalencia de normopeso del 85,01%, frente a una tasa de sobrepeso del 9,99% y de obesidad del 4,99% para ambos sexos y con independencia de la edad. El estudio metabólico evidenció niveles séricos significativamente más elevados (p < 0,0001) de HBA1c, insulina basal, glucemia basal, NEFA basal, lipoproteína (a) y HOMA IR entre adolescentes con obesidad frente a aquellos otros en situación de normopeso o sobrepeso. Conclusiones: La obesidad constituye un grave problema de salud entre la población de adolescentes estudiada, determinado el desarrollo precoz de trastornos metabólicos, hasta ahora propios de la etapa adulta circunstancia

    The main focus of this article is to present some impressions about the way some teachers appropriated of the tools from the ASTRONOMY TEACHING KIT (KITPEA). The subjects of this research were teachers that took part in the astronomy teaching specialization course offered by the Continuing Education Project (FOCO) at Math and Science Teaching Center (CECIMIG) from the School of Education of Federal University of Minas Gerais (FaE/UFMG). The data was collected with the use of a questionnaire and of an interview applied to these teachers. The analysis of the data was structured with the aid of the Activity Theory and the Mediated Action Theory. We interpret the teachers' speech using the constitutive aspects of the activity system and the concepts of appropriation and domain as an analytical device. It was possible to recognize the appropriation of the tools in 7 narratives among the 11 individuals who took part in the research. El objetivo principal de ese artículo es presentar indicaciones sobre la manera como algunos maestros se apropiaron de las herramientas del KIT PARA LA ENSEÑANZA DE LA ASTRONOMÍA (KITPEA). Los sujetos de esa investigación son docentes que participaron del curso de especialización en enseñanza de astronomía ofrecido por el Proyecto de Formación Continua (Foco) en el Centro de Enseñanza de Ciencias y Matemática (CECIMIG) de la Facultad de Educación de la Universidad Federal de Minas Gerais (FaE/UFMG). Recogimos las informaciones a través de un cuestionario y de una encuesta, aplicados a esos docentes. Estructuramos el análisis de esas informaciones con la ayuda de la Teoría de la Actividad y de la Teoría de la Acción Mediada. Interpretamos os discursos de los docentes usando como dispositivo analítico los elementos constitutivos del sistema de actividad y los conceptos apropiación y dominio. Entre los 11 sujetos que participaron de la investigación, fue posible interpretar con claridad la apropiación de las herramientas en

    This work examines the relationship between population growth and economic development in Latin America and assesses progress in the 10 years since the Bucharest World Population Conference. The Latin American population increased from about 159 million in 1950 to 275 million in 1970 and around 325 million in 1980. The rate of growth reached a maximum of 2.8%/year in the early 1970s and has now declined to about 2.3%/year. The regional growth rate is a product of population dynamics that differ greatly in individual countries. Crude birth rates declined in every country of Latin America between 1975-80, but still exceeded 40/1000 in 1980-85 in Bolivia, Ecuador, El Salvador, Haiti, Honduras, and Nicaragua. Current fertility is the result of the different trajectories of the demographic transition in different countries. While fertility in Argentina, Cuba, and Uruguay underwent a slow but sustained decline that began prior to 1960, other countries including Colombia, Costa Rica, Chile, and Venezuela began an accelerated fertility decline in the 1960s that diffused rapidly through all age and social groups. Other countries have still not entered a definite phase of fertility decline. Mortality rates have declined appreciably in Latin America in the past few decades although they remain high in some countries. After the end of World War II and until the mid-1970s, most countries of the region experienced rapid economic growth coupled with profound changes in the productive structure. The industrial labor force grew in almost all countries along with urbanization, the decline of agricultural employment, and the increase of the tertiary sector. These and other important economic advances through the mid-1970s occurred despite rapid population growth, and the beginning of the fertility decline coincided with slowing economic growth that saw negative rates in 1981-82. Various studies have shown that not all population sectors were incorporated in the process of economic and social development. The proportion of the population in active age groups has increased dramatically, but no corresponding increase in employment opportunities has occurred. The informal sector has absorbed most of the excess growth, a trend reflected in the exclusion of a large segment of the population from the fruits of economic progress. Population growth and increased life expectancy have created demands for more retirement benefits, health and educational services, transportation, recreation, and housing. Nevertheless, it cannot be concluded that rapid population growth necessarily has negative consequences for economic development or social welfare. There are indications that the problem of poverty in Latin America could be solved if the political will to do so existed; obstacles to overcoming poverty are not primarily material or population-related. Urbanization, settlement of marginal areas, and relative decline of agricultural areas are 3 trends in spatial distribution of varying intensity and repercussions in different countries.

    The Rhéouis and Boudinar Eocene outcrops located along the Tunisian 'north-south axis' show continental deposits similar to those already described in the west-central and meridional Atlas in the Jebel Chaambi and Chebket Bouloufa. The field investigations of these levels conduct to the discovery of Bulimes' terrestrial Gastropods known in the Mediterranean domain. The presence of palygorskite in the clay minerals confirms the emerged tendency of these deposits. The continental palaeogeography might have been induced by the Triassic halokinetic movements along the Atlasic anticlines.

    Atmospheric aerosol particles were collected from January to December 2007 at two sites in the City of Guadalajara. The first site (Centro) is located in the downtown, which is characterized by high vehicular traffic, and the second site (Miravalle) is in the southern part of the city, characterized by emissions from high industrial and vehicular activity. Sulfates, nitrates, and ammonium were the most abundant ions at both sites. Similar concentrations of sulfates, nitrates, and ammonium were observed throughout the year at Centro while only sulfates and nitrates were similar at Miravalle. From the balance of anions and cations at the two sites, Centro was determined to have acidic particles, while at Miravalle, the particles were alkaline. Based on the analysis of the ammonium/sulfate molar ratios, it was determined that in Centro, there was not enough ammonium to neutralize the sulfate, while at Miravalle, ammonium practically neutralized all sulfate.

    Introducción: La rehabilitación respiratoria es un pilar fundamental en el tratamiento del paciente con Enfermedad Pulmonar Obstructiva Crónica. Reduce importantemente los costos para el sistema de salud, el uso de recursos sanitarios, disminuyendo la estadía hospitalaria y las consultas a servicios de urgencia. Objetivo: Describir la condición actual de la rehabilitación respiratoria en los centros de atención primaria ubicados en la región de Valparaíso. Método: Se aplicó una encuesta cerrada a cada profesional a cargo del área respiratoria en los centros de atención primaria de salud. La muestra estuvo conformada por 32 centros de salud correspondientes a las comunas de Valparaíso, Viña del Mar, Quilpué y Villa Alemana. Resultados: 9 centros (28%) del total de la muestra realizan rehabilitación respiratoria y el mismo número tiene un programa de rehabilitación estructurado. En 15 (47%) de los centros existe un Nutricionista dentro del equipo de salud. En el 100% de los centros se evalúa a los pacientes mediante espirometría y escalas de disnea. La mayoría de los centros (89%) realiza entrenamiento de extremidades superiores e inferiores. Dentro de los factores que limitan la realización de la rehabilitación respiratoria, 20 (63%) centros refieren que el horario de atención es uno de los factores más limitantes, mientras que 23 (72%) centros refieren que no cuentan con espacio físico adecuado y 22 (69%) centros relatan no contar con los implementos mínimos necesarios. Discusión: Los datos obtenidos indican que en la mayoría de los centros encuestados no se realiza rehabilitación respiratoria como parte del tratamiento del paciente con Enfermedad Pulmonar Obstructiva Crónica, principalmente por problemas de recursos humanos, materiales e infraestructura.

    Using the properties of quantum parametric oscillators, two quantities are identified which increase monotonically in time in the process of parametric amplification. The use of these quantities as possible measures of entropy generation in vacuum cosmological particle creation is suggested. These quantities which are of complementary nature are both related to the number of particles spontaneously created.

    We consider a generalization to branes of the old action for the strings without reparamentrization invariance. These actions admit natural supplementary mass-shell conditions. By regularizing the Casimir energies we calculate the special dimensions at which these toy branes show vector massless states in its spectrum. They all turn out to be non-integers.

    Este trabajo de investigacion supone un modelo teorico de caracter aplicado, que proporciona la oportunidad de evaluar la produccion cientifica de los investigadores. Se encuadra dentro de la tradiccion de la estadistica aplicada y la sociologia del conocimiento. Atiende especialmente a dos conjuntos de temas de interes, por una parte, las caracteristicas principales que determinan el nivel y tipo de produccion academica producida por las unidades de investigacion y por los propios investigadores; por otra, la utilizacion que se hace de los metodos y tecnicas de investigacion puesto que de ello tambien depende el modo de produccion cientifica. Los puntos novedosos de esta tesis son: la medicion cuantitativa del objeto de estudio, la suma de los productos y las condiciones externas a la produccion del conocimiento mas otros elementos internos como las caracteristicas de los investigadores y la metodologia utilizada para desarrollar sus trabajos; y, finalmente, el uso de las nuevas tecnologias. El aprovechamiento de los recursos estadisticos y las fuentes de informacion secundarias se complementan con el diseno propio de una encuesta donde se implementa las caracteristicas descritas en un capitulo anterior sobre los metodos cientificos mas idoneos descritos en los principales manuales y articulos cientificos desde distintas disciplinas de conocimiento. Dicha encuesta ha sido desarrollada como un programa propio y en base a los mas innovadores usos de la tecnologia en la metodologia de encuestas.

    Introducción. El contexto escolar destaca como uno de los factores influyentes en las prácticas alimentarias de los-las adolescentes. Las prácticas de consumo alimentario durante la jornada escolar, la oferta de las cafeterías y las actividades de promoción propuestas desde los centros son objetos de atención creciente para la salud comunitaria. Objetivos. Describir las prácticas alimentarias del alumnado durante la jornada escolar; conocer la oferta de las cafeterías escolares y establecimientos periféricos; y valorar si los centros de secundaria son entornos favorecedores de una alimentación saludable. Diseño y muestra. Estudio descriptivo transversal durante los cursos 2010-2012. Unidades de muestreo: centros de secundaria públicos (95) y alumnado (8.068). Muestreo polietápico por conglomerados: selección aleatoria y estratificada por provincia y tamaño de hábitat. Elección del alumnado: muestreo sistemático de aulas. Resultados. El 77,5% del alumnado desayuna en casa: lácteo con cereal (40,9%) o ingesta líquida (29,2%); el 70,3% come algo en el centro y eligen el bocadillo de embutidos mayoritariamente. La fruta, anecdótica (2,5%) y, el zumo comercial, my frecuente (63,3%). El 75% consume chucherías siendo significativamente superior en centros con cafeterías. Las cafeterías ofertan multitud de productos desaconsejados: refrescos (97,3%), embutidos (91,8%), golosinas y fritos envasados (89%). Ausencia de control de la oferta en los centros (68,42%); solo el 28,4% de directivos conocen la ley que la regula. El 72,5% de los centros realiza promoción de la alimentación con rasgos de efemérides. El 71,5% de los centros tienen en sus alrededores comercios que abastecen al alumnado. Discusión. Encontramos una baja protección de la salud alimentaria del alumnado debido a: déficits alimentarios del alumnado; baja calidad de la oferta en cafeterías escolares y locales externos e inexistencia de actividades de promoción en los centros

    PM2.5 samples were collected at two locations in Guadalajara: Centro and Miravalle, during 2007. The first site (Centro) is located downtown and characterized by high vehicular traffic. Miravalle is in the southern part of the city, and influenced by emissions from high industrial and vehicular activity. Samples were collected for 24 h and the annual median concentrations of PM2.5 observed were 44.1 and 52.8 microg m(-3) at Centro and Miravalle, respectively. The concentration of PM2.5 observed at the Miravalle site was significantly higher (p < 0.002). Ca, Fe, Zn, Mg and Pb were the most abundant elements found at both sites. Miravalle showed higher annual concentrations of Ca, Pb, Cu, Cr, Sr, Ni, Mo, Fe, Mn, and Sb with levels of 1013.9, 74.9, 28.2, 9.4, 6.3, 4.4, 1.0, 628.0, 23.7 and 4.6 ng m(-3), respectively. At Centro and Miravalle quarterly and annual concentrations of Pb did not exceed 290 ng m(-3) and all values are well below those specified by air quality standards. The Principal Component Analysis (PCA), Cluster Analysis and the enrichment factor (EF) based on the concentrations of each element indicated that the main source of particulates at Centro was of geological origin, while Miravalle receives emissions from natural and anthropogenic sources. Both contribute to the chemical composition of PM2.5 in Guadalajara.

    Ambient PM2.5 samples were taken at 24 h intervals at two sites (Centro and Miravalle) in the city of Guadalajara from January to June 2008. The Centro site is located in the downtown, while the Miravalle site is located in an industrial zone south of the downtown. For both sites the higher concentrations of PM2.5 were between January and May. High correlation coefficients between sulfate, nitrate and ammonium of 0.95, 0.92 and 0.91, respectively, showed low variations in the concentrations of these species in the city. It was estimated that sulfate, nitrate and ammonium represented almost 47% of the PM2.5 mass in June at the Centro site, but in general the contributions in the other months were less than 21%, while at Miravalle this percentage was between 7.7% and 27.6%.

    During many years of teaching Physics at the Facultad de Ingeniería-Universidad de Buenos Aires (FIUBA) and at the Teachers School IES N°1, we have found that students usually have problems in understanding various items of Optics. In this work, we present the difficulties that appear during the teaching and learning processes and some of its causes. We propose a teaching method to make processes easier, to enable a better understanding and a long lasting retention of these topics in the cognitive structure of our students.

    For the last 15 years we have promoted experimental work even in the theoretical courses. Fluids appear in the Physics curriculum of the National University of Mexico in two courses: Collective Phenomena in their sophomore year and Continuum Mechanics in their senior year. In both, students are asked for a final project. Surprisingly, at least 85% choose an experimental subject even though this means working extra hours every week. Some of the experiments were shown in this congress two years ago. This time we present some new results and the methodology we use in the classroom.

    This paper shows four residential projects, carried out by the third year MGL + P Unit, at the Facultad de Arquitectura Universidad del Zulia, Maracaibo, Venezuela. The projects are adapted to a hot-humid climate, and assume bioclimatical responsibilities, according to an urban concept. This is how the Cinetic house, the Fissure house, the Infinite house and the Free house developed. In these projects, climatic and ecological variables like sunning, ventilation, illumination, thermal comfort, materials and bioclimatic landscape were given special consideration. The models have been tested in a heliodom and a wind tunnel looking for an architecture that conciliates space, climate and ecology in tropical regions of the Third World.

    Ramos Pastrana, Nilsa

    El Senado Academico del Recinto de Rio Piedras de la Universidad de Puerto Rico aprobo en el ano academico 2005-2006 la Certificacion 46, que contiene los lineamientos de un nuevo bachillerato. Este nuevo bachillerato introdujo cambios significativos en el curriculo tradicional. Entre ellos se encuentra la reduccion del componente de educacion general y el de Ciencias Biologicas en particular. La reduccion de creditos en el componente de Ciencias Biologicas ha obligado a reevaluar el concepto de cultura cientifica que desarrollan esos cursos. El proposito del estudio consistio en auscultar las percepciones de los profesores de las Facultades de Administracion de Empresas, Humanidades, Ciencias Sociales, Ciencias Naturales, Educacion y Estudios Generales del Recinto de Rio Piedras de la Universidad de Puerto Rico en torno al concepto de cultura cientifica, los contenidos disciplinares del curso de Ciencias Biologicas y la reduccion de creditos en el nuevo bachillerato. Las preguntas que guiaron la investigacion fueron: ¿cuales son las percepciones que tienen los profesores de las Facultades de Administracion de Empresas, Ciencias Sociales, Estudios Generales, Ciencias Naturales, Humanidades y Educacion, en torno al concepto de cultura cientifica y los contenidos disciplinares del curso de Ciencias Biologicas? ¿cuales son las percepciones que tienen los profesores de Ciencias Biologicas en torno al concepto cultura cientifica y los contenidos disciplinares del curso de Ciencias Biologicas? ¿existen diferencias significativas por facultad, genero, experiencia, rango y nombramiento en las percepciones que tienen los profesores del Recinto de Rio Piedras de la Universidad de Puerto Rico sobre los elementos que caracterizan la cultura cientifica y los contenidos biologicos que deben tener los egresados del Recinto? ¿que implicaciones curriculares tienen estos testimonios en el desarrollo del concepto de cultura cientifica en el nuevo bachillerato?

    The museums of Botany, Mineralogy and Zoology of the Facultad de Ciencias Físico-Matemáticas were created along with a world wide phenomenon, defined by some authors as the "museum movement," in a time the basics of this movement were being restructured. Thus, this work intends to go over the building stage of the natural history museums in a peripheral domain --- Cordoba by the end of the 19th century --- in order to partially understand this transition process. The strategy is to analyze the collections and find out how and why they were gathered. Two other aspects are also relevant: the human resources and the funds these institutions were granted.

  3. On the width of Σ hypernuclei and Σ- atoms

    NASA Astrophysics Data System (ADS)

    Brockmann, R.; Oset, E.

    1982-12-01

    The self-energy of a Σ particle in symmetric nuclear matter is investigated by using a boson exchange model for the ΣN interaction. The imaginary part of the self-energy is shown to be strongly density dependent and has saturation properties around ϱ ≌ 0.7 ϱo. This peculiar feature allows our results to be in good agreement with the Σ atom data while simultaneously providing a width of about 5 Mev or smaller for all nuclei and different states.

    Lasers and high speed cameras are a wonderful tool to visualize the very complex behavior of fluids, and to help students grasp concepts like turbulence, surface tension and vorticity. In this work we present experiments done by physics students in their senior year at the School of Science of the National University of Mexico as a final project in the continuum mechanics course. Every semester, the students make an oral presentation of their work and videos and images are kept in the web page ``Pasión por los Fluidos''.

    PubMed

    Graue-Wiechers, Enrique

    2011-01-01

    Nowadays surgery cannot be conceived as independent from medicine; consequently, surgical education cannot be far from the main principles of medical education. This review underlines the characteristics of medical training in the field of surgery. General physicians should be trained to perform surgical procedures under particular situations. A new lesson plan was implemented at the Facultad de Medicina in Mexico City (UNAM), comprised of eight fundamental surgical skills. A well-structured surgical program implies clear and exact definitions of the skills to be acquired during training as well as an appropriate follow-up, knowledge reinforcement, continuing educational skills, application of medical tests for patient care and evaluation of the learning process.

    Cáceres, Manuel O.; Diaz, Mario C.; Pullin, Jorge A.

    1987-08-01

    The behavior of a radiation filled de Sitter universe in which the equation of state is perturbed by a stochastic term is studied. The corresponding two-dimensional Fokker-Planck equation is solved. The finiteness of the cosmological constant appears to be a necessary condition for the stability of the model which undergoes an exponentially expanding state.

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

    Introducción: la desnutrición relacionada con la enfermedad (DRE) es un problema sociosanitario frecuente que afecta preferentemente a los mayores de 65 años, que aumenta la morbimortalidad y disminuye la calidad de vida.  Objetivo: estudiar la prevalencia de DRE en mayores de 65 años en diferentes centros sociosanitarios del Servicio Regional de Bienestar Social de la Comunidad de Madrid. Métodos: estudio transversal en 33 centros sociosanitarios de Madrid (6 centros de atención primaria [AP], 9 centros de mayores [CM], 9 hospitales [H] y 9 residencias [R]) seleccionados mediante muestreo polietápico. Las variables estudiadas fueron edad, sexo, nivel de dependencia según la escala de incapacidad de la Cruz Roja, motivo de ingreso y enfermedad de base, hábitat (urbano-periurbano-rural) y distribución geográfica (norte centro-sur). Como herramienta de cribado nutricional se utilizó el Mini Nutritional Assessment (MNA-cribaje) en todos los centros. En los pacientes con cribado positivo (en riesgo-desnutrición) se realizó el MNA-evaluación. El estudio estadístico se realizó con el paquete SSS 21.0 e incluyó estadística descriptiva, test de Chi-cuadrado y prueba exacta de Fisher, ANOVA de un factor, Kruskal-Wallis y análisis de regresión logística (RL) binaria univariante y multivariante. Se consideró significación estadística p < 0,05. Resultados: se reclutaron 1.103 sujetos (275 AP, 278 CM, 281 H, 269 R), edad media de 79,5 ± 8,4 años (41,2% varones, 58,8% mujeres). Los sujetos procedentes de H y R tuvieron un mayor grado de incapacidad (p < 0,001). La prevalencia global de DRE fue del 10%, encontrándose un 23,3% en riesgo de desnutrición, con diferencias entre los cuatro tipos de centros sociosanitarios (p < 0,001). El análisis univariante de RL mostró diferencia significativas en la prevalencia de desnutrición según la edad, sexo, grado de dependencia, tipo de centro sociosanitario, hábitat y zona geográfica.

    2016-04-01

    Iterative phase retrieval of complex valued objects (phase objects) suffers from twin image problem due to the presence of features of image and its complex conjugate in the recovered solution. The twin-image problem becomes more severe when object support is centro-symmetric. In this paper, we demonstrate that by modifying standard Hybrid-Input output (HIO) algorithm using an adaptive sparsity enhancement step, the twin-image problem can be addressed successfully even when the object support is centro-symmetric. Adaptive sparsity enhanced algorithm and numerical simulation for binary as well as gray scale phase objects are presented. The high quality phase recovery results presented here show the effectiveness of adaptive sparsity enhanced algorithm.

    In March 2004 was accepted in the site of Gran Telescopio Canarias (GTC) in La Palma Island, Spain, the Commissioning Instrument (CI) for the GTC. During the GTC integration phase, the CI will be a diagnostic tool for performance verification. The CI features four operation modes-imaging, pupil imaging, Curvature Wave-front sensing (WFS), and high resolution Shack-Hartmann WFS. This instrument was built by the Instituto de Astronomia UNAM in Mexico City and the Centro de Ingenieria y Desarrollo Industrial (CIDESI) in Queretaro, Qro under a GRANTECAN contract after an international public bid. Some optical components were built by Centro de Investigaciones en Optica (CIO) in Leon Gto and the biggest mechanical parts were manufactured by Vatech in Morelia Mich. In this paper we made a general description of the CI and we relate how this instrument, build under international standards, was entirely made in Mexico.

    The Law that led to the foundation of the Seguro Social was enacted on December 31st 1942, and later it was amended in 1945 to give rise to the Instituto Mexicano del Seguro Social. The first 10 years were characterized by the integration and acceptance of healthcare services from the social security point of view. In the 50s, with the construction of the Hospital La Raza, and in the 60s, with the construction of the Centro Medico Nacional, an expansion took place with the creation of several specialty units. The Hospital de Pediatría from the Centro Médico Nacional was one of them. A brief historical description of its origins is presented, and most importantly, of the impact it had on Mexican medicine.

    An international comparison on semi-standard Platinum Resistance Thermometers (PRTs) among the National Metrology Institutes (NMIs) of Spain, Mexico and the Andean Countries (Bolivia, Colombia, Ecuador, Peru and Venezuela) began in 2004 and was successfully completed in 2005. Two PRTs were circulated (hand carried) and compared from -40 °C up to 250 °C. The Centro Español de Metrología (Spanish NMI), CEM, was the pilot laboratory and the Centro Nacional de Metrología (Mexican NMI), CENAM, was the co-pilot laboratory. This paper shows the details of the comparison and the final results as they were presented in the approved final report of the comparison in September of 2005.

  6. Heavy metal contamination in little owl (Athene noctua) and common buzzard (Buteo buteo) from northern Italy.

    2005-01-01

    In this study, two raptor species, the common buzzard (Buteo buteo) and the little owl (Athene noctua), were investigated for lead and cadmium concentrations, using liver, kidneys, pectoral muscle, sternum bone, and feathers. All the collected birds died at the Centro Recupero Rapaci of Lega Italiana Protezione Uccelli in Sala Baganza (Parma, Italy). They arrived alive at the Centro between November 1998 and November 1999 but died or were put to death as a consequence of injuries or other ailments. The results of the investigation do not show an excessive exposure to cadmium, whereas some interesting data have emerged in the case of lead. The concentration of the latter in the liver and in the bone of two little owls seem to suggest the possibility of chronic exposure. The high values found in one common buzzard, on the other hand, suggest an acute exposure and, probably, a case of lead shot ingestion.

  7. Influence of thermal light correlations on photosynthetic structures

    The thermal light from the sun is characterized by both classical and quantum mechanical correlations. These correlations have left a fingerprint on the natural harvesting structures developed through five billion years of evolutionary pressure, specially in photosynthetic organisms. In this work, based upon previous extensive studies of spatio-temporal correlations of light fields, we hypothesize that structures involving photosensitive pigments like those present in purple bacteria vesicles emerge as an evolutionary response to the different properties of incident light. By using burstiness and memory as measures that quantify higher moments of the photon arrival statistics, we generate photon-time traces. They are used to simulate absorption on detectors spatially extended over regions comparable to these light fields coherence length. Finally, we provide some insights into the connection between these photo-statistical features with the photosynthetic membrane architecture and the lights' spatial correlation.

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

    This work shows the results obtained from the "O4K" Project supported by International Society for Optics and Photonis (SPIE) and the Universidad Autonoma de Nuevo Leon (UANL) through its SPIE Student Chapter and the Dr. Juan Carlos Ruiz-Mendoza, outreach coordinator of the Facultad de Ciencias Fisico Matematicas of the UANL. Undergraduate and graduate students designed Optics representative activities using easy-access materials that allow the interaction of children with optics over the exploration, observation and experimentation, taking as premise that the best way to learn Science is the interaction with it. Several activities were realized through the 2011-2013 events with 1,600 kids with ages from 10 to 12; the results were analyzed using surveys. One of the principal conclusions is that in most of the cases the children changed their opinions about Sciences in a positive way.

    2015-12-01

    San Antonio College is the oldest, largest and centrally-located campus of Alamo Colleges, a network of five community colleges based around San Antonio, Texas with a headcount enrollment of approximately 20,000 students. The student population is diverse in ethnicity, age and income; and the Colleges understand that they play a salient role in educating its students on the foreseen impacts of climate change. This presentation will discuss the key investment Alamo Colleges has adopted to incorporate sustainability and climate science into non-traditional classrooms. The established courses that cover climate-related course material have historically had low enrollments. One of the most significant challenges is informing the student population of the value of this class both in their academic career and in their personal lives. By hosting these lessons in hands-on simulations and demonstrations that are accessible and understandable to students of any age, and pursuing any major, we have found an exciting way to teach all students about climate change and identify solutions. San Antonio College (SAC) hosts the Bill R. Sinkin Eco Centro Community Center, completed in early 2014, that serves as an environmental hub for Alamo Colleges' staff and students as well as the San Antonio community. The center actively engages staff and faculty during training days in sustainability by presenting information on Eco Centro, personal sustainability habits, and inviting faculty to bring their classes for a tour and sustainability primer for students. The Centro has hosted professors from diverse disciplines that include Architecture, Psychology, Engineering, Science, English, Fine Arts, and International Studies to bring their classes to center to learn about energy, water conservation, landscaping, and green building. Additionally, Eco Centro encourages and assists students with research projects, including a solar-hydroponic project currently under development with the support

    The long-distant earthquake loading from Sumatra and Java Island had caused some slight damages to precast and reinforced concrete buildings in West Malaysia such as cracks on wall panels, columns and beams. Subsequently, the safety of existing precast concrete building is needed to be analyzed because these buildings were designed using BS 8110 which did not include the seismic loading in the design. Thus, this paper emphasizes on the seismic performance and dynamic behavior of precast school building constructed in Malaysia under three selected past earthquakes excitations ; El Centro 1940 North-South, El Centro East-West components and San Fernando 1971 using RUAUMOKO 2D program. This program is fully utilized by using prototype precast school model and dynamic non-linear time history analysis. From the results, it can be concluded that two-storey precast school building has experienced severe damage and partial collapse especially at beam-column joint under San Fernando and El Centro North-South Earthquake as its exceeds the allowable inter-storey drift and displacement as specified in Eurocode 8. The San Fernando earthquake has produced a massive destruction to the precast building under viscous damping, ξ = 5% and this building has generated maximum building displacement of 435mm, maximum building drift of 0.68% and maximum bending moment at 8458kNm.

  18. Centrosymmetry enhances quantum transport in disordered molecular networks

    For more than 50 years we have known that photosynthetic systems harvest solar energy with almost unit quantum efficiency. However, recent experimental evidence of quantum coherence during the excitonic energy transport in photosynthetic organisms challenges our understanding of this fundamental biological function. Currently, and despite numerous efforts, the causal connection between coherence and efficiency is still a matter of debate. We show, through extensive simulations of quantum coherent transport on networks, that three dimensional structures characterized by centro-symmetric Hamiltonians are statistically more efficient than random arrangements. Moreover, a strong correlation of centro-symmetry with quantum efficiency is also observed under the coherent transport dynamics induced by experimentally estimated electronic Hamiltonians of the Fenna-Mathew-Olson complex of sulfur bacteria and of the cryptophyte PC645 complex of marine algae. The application of a genetic algorithm results in a set of optimized Hamiltonians only when seeded from the experimentally estimated Hamiltonian. These results suggest that what appears to be geometrically disordered complexes may well exhibit an inherent hidden symmetry which enhances the energy transport between chromophores. We are confident that our results will motivate research to explore the properties of nearly centro-symmetric Hamiltonians in realistic environments, and to unveil the role of symmetries for quantum effects in biology. The unravelling of such symmetries may open novel perspectives and suggest new design principles in the development of artificial devices.

    Los modelos de Heggie y Ramamani de satélites galácticos en órbitas circulares se basan en una teoría aproximada, por lo que es importante verificar su estabilidad mediante simulaciones numéricas. En esta forma, hemos logrado mostrar que son estables sobre intervalos de tiempo mucho mayores que los que lograron los propios autores de los modelos. Por otra parte, dado que hemos mostrado que el caos es significativo en estos modelos, son un sistema ideal para investigar si, pese a ello, se mantienen estacionarios. Nuestras simulaciones numéricas muestran que, pese al caos, la estacionariedad se mantiene sobre intervalos de centenares de tiempos de cruce del sistema, mucho mayores que los tiempos de Liapunov característicos de sus movimientos caóticos.

    En un trabajo anterior mostramos que el caos podía ser significativo en satélites galácticos. Ahora hemos clasificado órbitas en modelos de Heggie-Ramamani que tienen la ventaja de ser autoconsistentes y de que se conoce su función de distribución. Hemos podido así determinar porcentajes de órbitas caóticas, que resultan ser de entre 25% y 65%, según el modelo considerado. La dependencia de la caoticidad con la energía orbital es complicada y sugiere que el origen de la caoticidad se halla en la acción combinada de la fuerza de atracción del propio satélite con la fuerza de Coriolis y la fuerza centrifuga.

  1. Proyecto para la medición sistemática de seeing en CASLEO

    Fernández Lajus, E.; Forte, J. C.

    La calidad del seeing astronómico es ciertamente uno de los parámetros mas importantes que caracterizan el sitio de un observatorio. Por tanto se desea determinar si el alto valor de seeing observado con el telescopio de 2.15 m se debe a efectos internos y/o del entorno a la cupula o si se debe simplemente al seeing propio del lugar. El actual mecanismo de refrigeración del espejo primario del 2.15, parece haber mejorado notablemente la calidad del seeing. Sin embargo se hace necesario saber hasta que punto el valor del seeing puede ser mejorado. La primera etapa del proyecto consistió en la puesta a punto del telescopio emplazado para este propósito y la adquisición de las primeras medidas tentativas de seeing.

    Objetivos: Valorar el estado nutricional en adultos mayores autónomos, no institucionalizados, en centros sociales, mediante la escala MNA y analizar su distribución según las variables sociodemográficas: sexo, edad, estado civil, convivencia, estudios y ámbito rural o urbano. Métodos: Estudio transversal realizado en 660 adultos mayores autónomos, no institucionalizados en centros sociales de la provincia de Valencia. Los sujetos fueron evaluados en 12 centros sociales seleccionados mediante un muestreo estratificado por bloques. Los criterios de inclusión en el estudio fueron: tener 65 años o más, vivir en el domicilio, tener autonomía funcional, residir más de un año en la provincia de Valencia, acudir periódicamente a centros sociales y querer colaborar. Se usó el MNA para la valoración nutricional. Resultados: De los 660 sujetos incluidos en el estudio, el 48,33% son hombres y el 51,6% mujeres, la edad media es de 74,3 ± 6,57 años. El 23,3% de los encuestados presenta riesgo de malnutrición. El odds de prevalencia del riesgo de malnutrición es mayor en: mujeres respecto a hombres (OR = 1,43), personas ≥?85 años respecto al grupo de 65-69 años (OR = 2,27), personas viudas respecto a casadas o con pareja estable (OR = 1,82) y en personas sin estudios respecto a las que disponen de algún nivel de estudios (OR = 1,73). Conclusiones: La prevalencia de riesgo nutricional en adultos mayores autónomos, no institucionalizados en centros sociales de la provincia de Valencia alcanza a una de cada cuatro personas, siendo más elevada en personas viudas (en su mayor parte mujeres mayores, que viven solas) y en personas sin estudios.

    This volume of Journal of Physics: Conference Series contains selected articles by the participants at the International Conference on Control and Synchronization of Dynamical Systems (CSDS-2005) organized by Centro de Investigaciones en Optica (CIO) in cooperation with the Society for Industrial and Applied Mathematics (SIAM), which was held in Leon, Guanajuato, Mexico on 4-7 October 2005. CSDS-2005 featured the latest research in nonlinear dynamics concentrating on the theory of control and synchronization of complex systems and its applications in different areas of science and engineering, including optics, electronics, mechanics, chemistry, medicine, economy, communication, etc. The conference brought together leading researchers, both theoreticians and experimentalists, from different fields of science and provided an excellent opportunity for sharing ideas and problems among specialists in controlling dynamical systems and synchronization. The meeting served a dual purpose: to expose the scientific community to the cutting edge of forefront research done by leaders in this area from as many as 25 countries and to attract the attention of Mexican researchers to this field of science. These proceedings are intended to be a record of this conference and to serve as a reference for future research which the conference hopes to have initiated. After the pioneering work on controlling chaos of E Ott, C Grebogi and J Yorke appeared in Physical Review Letters in 1990, the number of works on this topic grew tremendously. Our extensive bibliographic search among 110 peer reviewed journals yielded more than 1500 papers on controlling chaos and more than 2500 on synchronization of chaotic systems published during the last decade. The numbers of publications are still at their peaks that began to saturate, in 1998 and 2003, respectively. It is my pleasure to acknowledge the contribution of the program and organizing committees, the funding agencies and cooperating

    Introducción: la nutrición parenteral (NP) es una mezcla que cubre las necesidades nutricionales cuando no es posible lograr esta tarea por la vía enteral en el paciente; sin embargo, no está exenta de complicaciones. El objetivo del estudio fue conocer la indicación y la frecuencia de complicaciones de la NP en pacientes pediátricos atendidos en un centro de tercer nivel. Métodos: se incluyeron niños que recibieron NP en el Hospital de Pediatría del Centro Médico Nacional Siglo XXI del Instituto Mexicano del Seguro Social. Se registraron las características demográficas, antropométricas, la causa de la indicación de la NP, su tiempo de administración y las complicaciones asociadas a este tipo de nutrición. Resultados: se incluyeron 69 pacientes pediátricos: 33 recién nacidos (RN) y 18 lactantes entre uno y 11 meses de edad; nueve preescolares entre uno y cinco años, y nueve niños mayores de cinco años. Las enfermedades del tracto digestivo tratadas quirúrgicamente constituyeron el 71 % de las indicaciones para el inicio de NP. Se presentaron complicaciones en el 87 % de los pacientes y 76.7% tuvieron más de una complicación. Las complicaciones metabólicas representaron 98 %, las mecánicas 1 % y las infecciosas 1 %. Conclusión: la NP en este centro de tercer nivel se indicó principalmente a pacientes sometidos a cirugía del tracto digestivo.

    Action words referring to face, arm or leg actions activate areas along the motor strip that also control the planning and execution of the actions specified by the words. This electroencephalogram (EEG) study aimed to test the learning profile of this language-induced motor activity. Participants were trained to associate novel verbal stimuli to videos of object-oriented hand and arm movements or animated visual images on two consecutive days. Each training session was preceded and followed by a test-session with isolated videos and verbal stimuli. We measured motor-related brain activity (reflected by a desynchronization in the μ frequency bands; 8-12 Hz range) localized at centro-parietal and fronto-central electrodes. We compared activity from viewing the videos to activity resulting from processing the language stimuli only. At centro-parietal electrodes, stable action-related μ suppression was observed during viewing of videos in each test-session of the two days. For processing of verbal stimuli associated with motor actions, a similar pattern of activity was evident only in the second test-session of Day 1. Over the fronto-central regions, μ suppression was observed in the second test-session of Day 2 for the videos and in the second test-session of Day 1 for the verbal stimuli. Whereas the centro-parietal μ suppression can be attributed to motor events actually experienced during training, the fronto-central μ suppression seems to serve as a convergence zone that mediates underspecified motor information. Consequently, sensory-motor reactivations through which concepts are comprehended seem to differ in neural dynamics from those implicated in their acquisition.

  7. Temporospatial dissociation of Pe subcomponents for perceived and unperceived errors.

    2012-01-01

    Previous research on performance monitoring revealed that errors are followed by an initial fronto-central negative deflection (error-related negativity, ERN or Ne) and a subsequent centro-parietal positivity (error positivity, Pe). It has been shown that error awareness mainly influences the Pe, whereas the ERN seems unaffected by conscious awareness of an error. The aim of the present study was to investigate the relation of ERN and Pe to error awareness in a visual size discrimination task in which errors are not elicited by impulsive responding but by perceptual difficulty. Further, we applied a temporospatial principal component analysis (PCA) to examine whether the temporospatial subcomponents of the Pe would differentially relate to error awareness. Event-related potential (ERP) results were in accordance with earlier studies: a significant error awareness effect was found for the Pe, but not for the ERN. Interestingly, a modulation with error perception on correct trials was found: correct responses considered as incorrect had larger correct-related negativity (CRN) and lager Pe amplitudes than correct responses considered as correct. The PCA yielded two relevant spatial factors accounting for the Pe (latency 300 ms). A temporospatial factor characterized by a centro-parietal positivity varied significantly with error awareness. Of the two temporospatial factors corresponding to ERN and CRN, one factor with central topography varied with response correctness and subjective error perception on correct responses. The PCA results indicate that the error awareness effect is specifically related to the centro-parietal subcomponent of the Pe. Since this component has also been shown to be related to the importance of an error, the present variation with error awareness indicates that this component is sensitive to the salience of an error and that salience secondarily may trigger error awareness.

    Introduccion. El ictus es una emergencia medica dependiente del tiempo. La rapidez en su reconocimiento y en la atencion que reciben los pacientes es clave en el pronostico. Objetivos. Analizar los tiempos de actuacion medica, evaluar posibles areas de mejora y estudiar la dotacion de recursos de los centros. Pacientes y metodos. Registro prospectivo de pacientes atendidos en ocho unidades de ictus experimentadas españolas con sospecha de ictus y activacion del codigo ictus. Se recogieron los tiempos inicio-puerta, puerta-tomografia computarizada (TC), puerta-aguja, TC-aguja e inicio-aguja. Tambien se recogieron el metodo de trasporte al hospital, el tipo de ictus y las terapias de reperfusion. En cuanto a la dotacion estructural de los centros, se recogieron la ratio de enfermeria, la monitorizacion de camas, la disponibilidad de TC multimodal y resonancia magnetica, y la realizacion de cursos de informacion o formacion. Resultados. Se incluyeron 197 pacientes, de los cuales fueron validos 181 (151 infartos y 30 hemorragias cerebrales). Las medianas (p25-p75) en minutos fueron: inicio-puerta, 104 (70-188); puerta-TC, 27 (19-41); TC-aguja, 30 (21-43); puerta-aguja, 64 (49-83); e inicio-aguja, 156 (129-202). Se aplicaron terapias de reperfusion en 68 pacientes (el 45% de los infartos cerebrales), de los cuales el 81% fueron trombolisis intravenosas; el 7%, tratamientos endovasculares; y el 12%, una combinacion de ambos. Los recursos de los centros estuvieron de acuerdo con lo recomendado por las guias clinicas. Hubo un bajo porcentaje de pacientes estudiados con resonancia magnetica. Conclusion. El porcentaje de pacientes tratados con trombolisis fue muy elevado y los tiempos de los circuitos intrahospitalarios, aunque buenos, tienen margen de mejora.

    Introducción: el fosfuro de zinc es usado para exterminar roedores; es un producto altamente tóxico, no crea resistencias y es de uso popular. Debido a que es un plaguicida altamente comercializado de elevada toxicidad que no cuenta con un antídoto disponible, es imperativo precisar e identificar con oportunidad las manifestaciones clínicas de la intoxicación. El objetivo fue describir el perfil epidemiológico y clínico de los niños intoxicados con fosfuro de zinc atendidos en un centro toxicológico de tercer nivel de atención. Métodos: estudio retrospectivo, observacional y trasversal del 2005 al 2015, con 36 registros de pacientes pediátricos atendidos en el Centro de Información y Atención Toxicológica del Hospital General “Dr. Gaudencio González Garza” del Centro Médico Nacional La Raza del Instituto Mexicano del Seguro Social. Resultados: el estudio no demostró predominio de algún género. El 66% de los pacientes se encontraba entre 1 y 2 años de edad. El 96% de los pacientes eran sanos y tres adolescentes utilizaron el producto con fines suicidas. La exposición ocurrió en el hogar. La toxicidad se caracterizó por hipotensión arterial, hipoglucemia, acidosis metabólica, dolor abdominal, náuseas, vómitos; ninguno de los pacientes falleció ni requirió de asistencia ventilatoria ni de hemodiálisis. Conclusión: la falta de conocimiento del potencial tóxico y la accesibilidad al producto en el interior del domicilio de los pacientes facilita su exposición; se trata de un riesgo 100% prevenible.

    Introducción: Un estado nutricional deficitario tiene importantes consecuencias en la salud de los colectivos en situación de especial vulnerabilidad, como las personas con enfermedades crónicas o personas mayores en situación de dependencia. Objetivo: Conocer el estado nutricional al ingreso de usuarios en centros SARquavitae. Material y Método: Se estudió el estado de salud, cognitivo y funcional de las personas que ingresaron durante el año 2012 en algún centro de la compañía. El estado nutricional fue evaluado mediante la versión corta del Mini Nutritional Assessment. Asimismo, se realizó un análisis para conocer las variables con mayor influencia en el estado nutricional de la muestra objeto de estudio. Resultados: Se analizaron las historias clínicas de 4.297 ingresos. La edad media fue de 82,08 años. Un 66,1% eran mujeres con una alta pluripatología. Al ingreso, un 30,4% de la muestra se encuentra en situación de desnutrición y un 49,4% en riesgo de desnutrición. Se observa una mayor prevalencia de desnutrición en mujeres, en aquellas personas que son derivadas por un hospital de agudos o por sus consultas externas, con peor estado funcional y cognitivo y en aquellas con procesos patológicos como demencia, enfermedades cerebrovasculares o disfagia. Conclusiones: Los resultados de este estudio ponen de manifiesto la alta complejidad clínica de las personas que ingresan en los centros residenciales estudiados, evidenciando la necesidad de realizar valoraciones integrales que permitan establecer planes de cuidados específicos para los perfiles atendidos.

    Objetivo: identificar mediante una encuesta los tratamientos fuera de la ficha tecnica (FFT) que mas frecuentemente se utilizan en el area de oncohematologia. Conocer los procedimientos y criterios que se han establecido para autorizar estos tratamientos. Método: se diseno una encuesta con cuatro secciones: 1) datos demograficos y de actividad del hospital, 2) procedimiento de utilizacion de medicamentos FFT, 3) criterios de aprobacion y 4) tratamientos oncologicos FFT tramitados durante el ano anterior. Resultados: en el 42,1% de los centros la proporcion en la que es necesaria autorizacion previa a la dispensacion es mayor del 80%. El factor mas importante que influye en el circuito de autorizacion-dispensacion de estos farmacos es la evidencia disponible. El procedimiento de autorizacion mas habitual es la autorizacion de la direccion del hospital previo informe del servicio de farmacia. En un 55,3% de los hospitales se han establecido criterios especificos del paciente que ayudan a la toma de decisiones, junto con los aspectos de eficacia y seguridad de los farmacos en la indicacion solicitada. En la mayoria de los centros se acepta un menor nivel de evidencia en el caso de que no existan alternativas terapeuticas, asi como en los tumores de baja prevalencia. La mayor parte de los centros no tienen claramente establecido un criterio de eficacia para considerar un beneficio como clinicamente relevante, y tampoco el umbral coste-eficacia para aprobar un FFT. Conclusiones: existe una gran variabilidad en el procedimiento de utilizacion de los FFT y en los criterios que se utilizan para su aprobacion.

  12. New solutions of the hamiltonian and diffeomorphism constraints of quantum gravity from a highest weight loop representation

    NASA Astrophysics Data System (ADS)

    Aldaya, V.; Navarro-Salas, J.

    1991-04-01

    We introduce a highest weight type representation of the Rovelli-Smolin algebra of loop observables for quantum gravity. In terms of this representation, new solutions of the hamiltonian and diffeomorphism constraints are given. Assuming the locality of the quantum hamiltonian constraint we show that any functional depending on the generalized link class of the disjoint union of arbitrary simple loops is a solution. Finally we argue that this is the general solution in the irreducible representation space.

    Argentina's Centro-Oeste (Central-West) Gas Pipeline is now a reality, carrying gas from the extensive Loma de la Lata (Hill of Tin) field in Neuquen State to cities which had been relying on bottled gas. The project is impressive, but hardly seems unique. A pipeline consisting of 697 miles of 30-in. line and 451 miles of smaller diameter gathering and distribution lines is a big project but nothing that has not been done before. Sometimes figures and statistics hide more than they reveal. A discussion is provided of project financing, logistics, pipeline outlets, treatment plants, route, construction, other lines, compressor stations, and suppliers.

    The experimental and theoretical bases for a synchronous or concerted double-proton transfer in centro-symmetric H-bonded electronically excited molecular dimers are presented. The prototype model is the 7-azaindole dimer. New research offers confirmation of a concerted mechanism for excited-state biprotonic transfer. Recent femtosecond photoionization and coulombic explosion techniques have given rise to time-of-flight MS observations suggesting sequential two-step biprotonic transfer for the same dimer. We interpret the overall species observed in the time-of-flight experiments as explicable without conflict with the concerted mechanism of proton transfer. PMID:10411876

    This work presents results obtained from a study of case for H-55 Helicopter System Identification which was carried out by an implementation of Quad-M Methodology purposed for Jategaonkar. The implementation performed was based on Cruz et al whose works were developed in Centro Técnico Aeroespacial (CTA). A comparison between Stability and Control Derivatives tables from these results and those from literature is performed for some important flight conditions. This comparison allows us to conclude about the reliability of the method, to present preliminary SCD tables for the studied aircraft and point to possible future works.

  20. Topologically-driven valley polarization in twisted graphene/hexagonal boron nitride heterostructures

    NASA Astrophysics Data System (ADS)

    Basile, Leonardo; Idrobo, Juan Carlos

    Valley polarization, that is, selective electronic localization in a momentum valley, has been proposed on materials presenting either a strong spin-orbit coupling (SOC) or with a weak SOC but in the presence of electric and magnetic fields. In this talk, we identify a non-centro symmetric system which can also present valley polarization purely by topological means without the necessity of SOC. We find that twisted bilayers of graphene/hexagonal boron nitride heterostructures have different absorption for right- and left- circular polarized light, indicating valley polarization. This induced polarization occurs due to band folding of the electronic bands, i.e., it has a topological origin.

    An edge detection algorithm has been applied to estimate left ventricular (LV) mass from single photon emission computed tomography (SPECT) thallium-201 images. The algorithm was validated using SPECT images of a phantom. The algorithm was applied to 20 patient studies from the Hospital de Cardiologia, Centro Médico Nacional Siglo XXI. Left ventricular masses derived from the stress and redistribution studies were highly correlated (r=0.96). The average LV masses obtained were 162±37 g and 169±34 g in the redistribution and stress studies, respectively.

    The case of a patient diagnosed with uterine cervix cancer is presented as an example of the clinical application of the radiobiological compensation method implemented at Centro Estatal de Cancerologia de Durango. Radiotherapy treatment was initially modified to compensate for the chemotherapy component and, as medical complications arose during treatment delivery resulting in an 18 days gap, new compensation followed. All physical and radiobiological assumptions to calculate the Biologically Effective Dose in the external beam and brachytherapy parts of the treatment are presented. Good local control of the tumor was achieved, the theoretical tolerance limits for the organs at risk were not surpassed and the patient manifested no extensive morbidity.

    In many applications, for example cryptography and Monte Carlo simulation, there is need for random numbers. Any procedure, algorithm or device which is intended to produce such is called a random number generator (RNG). What makes a good RNG? This paper gives an overview on empirical testing of the statistical properties of the sequences produced by RNGs and special software packages designed for that purpose. We also present the results of applying a particular test suite--TestU01-- to a family of RNGs currently being developed at the Centro Interdipartimentale Vito Volterra (CIVV), Roma, Italy.

O CEPROSOM contava com dois projetos: Projeto Centro de Convivência Infantil (CCI) e Programa Criança e Adolescente (PCA), que atendiam crianças e adolescentes em Centros Comunitários de diversas áreas da cidade. Esses projetos têm como prioridades estabelecer atividades prazerosas para as crianças no sentido de retirá-las das ruas. Assim sendo, as crianças passaram a ter mais um tipo de atividade - as visitas ao observatório. Este painel descreve as várias fases do projeto, que envolveu: reuniões de planejamento, curso de Astronomia para as orientadoras dos CCIs e PCAs, atividades relacionadas a visitas das crianças ao Observatório, proposta de construção de gnômons e relógios de Sol nos diversos Centros Comunitários de Limeira e divulgação do projeto na imprensa. O painel inclui discussões sobre a aprendizagem de crianças carentes, relatos que mostram a postura das orientadoras sobre a pertinência do ensino de Astronomia, relatos do monitor que fez o atendimento no Observatório e o que o número de crianças atendidas representou para as atividades da instituição desde o início de suas atividades e, em particular, em 2001. Os resultados são baseados na análise de relatos das orientadoras e do monitor do Observatório, registros de visitas e matérias da imprensa local.

    Rosacea is a common chronic inflammatory skin disease with a variety of clinical manifestations such as centro-facial erythema, papules and pustules, as well as ocular involvement. Based on these manifestations, rosacea is clinically divided into four subtypes necessitating distinct therapies. Despite recent scientific advances, the pathomechanisms underlying rosacea in general and the different subtypes in particular are still elusive. Accordingly, current treatment options remain mostly broad and symptomatic. In this review we discuss the clinic of rosacea, its impact on the patient, and the pathophysiological mechanisms involved, describe treatment options and highlight differential diagnoses relevant for treating physicians.

    and Thermohaline Structure of the Brazil Current Confluence System (BCCS) are stud-ied from climatic data, "Marathon Exp. Leg.8, 1984"data, and two Sea surface temperature (SST) data bases: "Meteor satellite"(1989-1994) and "ds277-Reynolds" (1981-2000).The South Atlantic Central Water (SACW) is divided in two main types: tropical (TW) and subtropical water (ST). Water masses, fronts, inter-frontal and frontal zones are analysed and classified: a) the water masses: Tropical Low-Salinity Water, Tropical Surface Water, Tropical Tropospheric Water, Subtropical Low-Salinity Water, Subtropical Surface Water, Subtropical Tropospheric Water. T,S characteristics of intermediate, deep and bottom water defined by different authors are confirmed and completed; b) the Inter-frontal Zones: Tropical/Brazil Current Zone, Sub-tropical Zone and Subantarctic Zone; c) the Frontal Zones: Subtropical, Subantarctic and Polar, and d) the Fronts: Subtropical Front of the Brazil Current, Principal Subtropical Front, North Subtropical Front, Subtropical Surface Front, South Subtropical Front, Subantarctic Surface Front, Subantarctic Front and Polar Front. Several stable T-S relationships are found below the friction layer and at the Fronts. The maximum gradient of the oceanographic characteris-tics occurs at the Brazil Current Front, which can be any of the subtropical fronts, depending on season.

    Introducción: La obesidad y el síndrome metabólico afectan a un segmento considerable de la población mundial, incluyendo a los profesionales de la salud. De hecho, diversos estudios han reportado que los médicos tienden a presentar más factores de riesgo cardiovascular que sus propios pacientes. El presente estudio transversal evaluó si los estudiantes del área de la salud tenían un estilo de vida más saludable y, por tanto, una mejor actitud en cuanto a la prevención de las enfermedades crónico-degenerativas, que el resto de la población. Materiales y métodos: Se encuestaron estudiantes del área medico-biológica a través de un cuestionario sobre antecedentes heredo-familiares de riesgo cardiovascular, consumo actual de tabaco y alcohol, así como hábitos alimentarios y de ejercicio físico. Se midió la presión arterial, el peos, la talla y la circunferencia abdominal. Resultados: 23.4% de los participantes presentaban sobrepeso y 10% obesidad. La obesidad paterna fue el factor de riesgo más frecuente, seguido de consumo social de alcohol y tabaquismo. Se encontró un alto consume de alimentos de origen animal, cereales industrializados y refrescos; por otra parte, se reportó un bajo consumo de verduras y frutas. Más de la mitad de la muestra refirió ser sedentario. Discusión y conclusiones: Se encontraron datos muy similares a aquéllos reportados sobre la población general, que eventualmente conducirán al desarrollo de enfermedades cardiometabólicas. Por tanto, es posible inferir que la educación biomédica no es eficiente en la inducción de un estilo de vida saludable entre los estudiantes de ciencias de la salud. Tal fenómeno podría impactar su práctica futura ya que probablemente se convertirán en profesionistas obesos, con la consecuente falla en la prevención primaria y secundaria de sus propios pacientes.

    Passive isolator, active vibration absorber, and an integrated passive/active (hybrid) control are studied for their effectiveness in reducing structural vibration under seismic excitations. For the passive isolator, a laminated rubber bearing base isolator which has been studied and used extensively by researchers and seismic designers is considered. An active vibration absorber concept, which can provide guaranteed closed-loop stability with minimum knowledge of the controlled system, is used to reduce the passive isolator displacement and to suppress the top floor vibration. A three-story building model is used for the numerical simulation. The performance of an active vibration absorber and a hybrid vibration controller in reducing peak structural responses is compared with the passively isolated structural response and with absence of vibration control systems under the N00W component of El Centro 1940 and N90W component of the Mexico City earthquake excitation records. The results show that the integrated passive/active vibration control system is most effective in suppressing the peak structural acceleration for the El Centro 1940 earthquake when compared with the passive or active vibration absorber alone. The active vibration absorber, however, is the only system that suppresses the peak acceleration of the structure for the Mexico City 1985 earthquake.

    Ritual use of ayahuasca, an amazonian Amerindian medicine turned sacrament in syncretic religions in Brazil, is rapidly growing around the world. Because of this internationalization, a comprehensive understanding of the pharmacological mechanisms of action of the brew and the neural correlates of the modified states of consciousness it induces is important. Employing a combination of electroencephalogram (EEG) recordings and quantification of ayahuasca's compounds and their metabolites in the systemic circulation we found ayahuasca to induce a biphasic effect in the brain. This effect was composed of reduced power in the alpha band (8-13 Hz) after 50 minutes from ingestion of the brew and increased slow- and fast-gamma power (30-50 and 50-100 Hz, respectively) between 75 and 125 minutes. Alpha power reductions were mostly located at left parieto-occipital cortex, slow-gamma power increase was observed at left centro-parieto-occipital, left fronto-temporal and right frontal cortices while fast-gamma increases were significant at left centro-parieto-occipital, left fronto-temporal, right frontal and right parieto-occipital cortices. These effects were significantly associated with circulating levels of ayahuasca's chemical compounds, mostly N,N-dimethyltryptamine (DMT), harmine, harmaline and tetrahydroharmine and some of their metabolites. An interpretation based on a cognitive and emotional framework relevant to the ritual use of ayahuasca, as well as it's potential therapeutic effects is offered.

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

    This text reproduces a speech given by Dr. Mario Testa on June 28, 1973 in the main hall of the Faculty of Medicine of the Universidad de Buenos Aires. The words of introduction preceding the text, written by Testa himself, provide the context of not only the historical moment the university was experiencing, just days after Rodolfo Puiggrós took office as the rector within the university's political overhaul, but also the meaning given to the project of pedagogical renovation. This project proposed redefining the relationship between the university and society, originating such projects such as the Instituto de Medicina del Trabajo (Institute of Occupational Medicine), the Instituto de la Madre y el Niño (Mother and Child Institute) and the Instituto de Patología Regional (Regional Pathology Institute) in the Faculty of Medicine; the Centro de Producción de Medicamentos de Base (the Center for Basic Drug Production) in the Faculty of Pharmacy and Biochemistry; and the Centro de Erradicación de Villas de Emergencia (Center for the Eradication of Shantytowns) in the Faculty of Architecture, among many others. Republishing these words, spoken almost 40 years ago, is a way of continuing to put into discussion the type of education and training health professionals receive with public funds.

    The aim of this study was to perform a survey on the prevalence of anti-Toxoplasma gondii antibodies in horses from Rio de Janeiro State, Brazil. From 2012 to 2013, a total of 624 blood samples were collected from horses from the eight regions comprising Rio de Janeiro State (Baixadas Litorâneas, Serrana, Norte Fluminense, Noroeste Fluminense, Centro-Sul, Metropolitana, Médio Paraíba, and Costa Verde). All sera samples were tested for anti-T. gondii antibodies by performing the modified agglutination test with a cut-off of 1:25. Positive serology for T. gondii was detected in 22.8% (142/624) of the horses studied. Seropositivity was detected in all regions sampled; furthermore, statistical significance was observed when all locations were compared at once. The Médio Paraíba region had the highest number of positive animals 54.76% (23/42) in the Bonferroni correction among Costa Verde, Centro Sul, Metropolitana, and Serrana (p<0.001). Seropositivity was 39.58% (38/96) in Norte Fluminense, which was the second most prevalent region. The results indicated that the T. gondii parasite is widely distributed in horses in Rio de Janeiro State and represents a risk to public and animal health. These findings emphasize the need to increase control and prevention of this disease in horses.

    Like many other countries and organizations, Spain has been developing a program to investigate the economic viability of new sources of energy. Among these, it should be pointed out, is included the large solar power systems. Within this investigation program, ''Centro de Estudios de la Energia'', an organization dependent on ''Ministerio de Industria y Energia'', is carrying out the CESA-1 Project, which consists of design, construction, start-up, and operation of a 1.2-MW Pilot Solar Power Plant. If the current technical uncertainties are removed and the power tower concept demonstrates its economical viability, Spain will be one of the most appropriate countries in the world for a full-scale implementation of this technology. For this reason, the ''Ministerio de Industria y Energia'' reached the conclusion in mid-1977 that it would be of interest to explore this technology using the domestic industrial potential. The project was approved by the Council of Ministers in June 1977 and the project begun in early 1978. The management of the Project is the direct responsibility of ''El Centro de Estudios de la Energia'' and was helped by the engineering firms Initec and Sener to attain the adequate organization to carry out the project.

    Diabetes is a widespread disease and its control is dependent upon the patient. Although there is no permanent cure for diabetes, there are several available treatments which, when followed regularly, allow the patient to have a good quality of life. Patient education, especially about eating habits, is key to keep glucose levels stable both in the short and in the long term. This should include nutritional counselling, physical exercise, and the self monitoring of glucose levels. The University of Coimbra and the Serviço de Endocrinologia, Diabetes e Metabolismo of Centro Hospitalar e Universitário de Coimbra started a collaboration to develop interactive tools for the learning and improvement of carbohydrate counting by patients. The approach presented in this paper is an interactive multimedia tool, available to patients through either the web or a smartphone. It helps them to learn how to maintain a healthy diet and how to monitor their insulin levels correctly by measuring the carbo-hidrate “equivalents” in meals. This application will create a more dynamic and interactive way of educating patients, improving solutions currently used in the Serviço de Endocrinologia, Diabetes e Metabolismo of the Centro Hospitalar e Universitário de Coimbra.

    Introduccion. La epilepsia es una enfermedad cronica que afecta al 0,5-1% de la poblacion, mayormente de inicio durante la infancia. Un tercio de los pacientes evoluciona hacia una forma refractaria al tratamiento con farmacos antiepilepticos, lo que plantea al equipo de salud un desafio terapeutico. La dieta cetogenica (DC) es un tratamiento no farmacologico efectivo utilizado como un metodo alternativo para el tratamiento de la epilepsia refractaria. Objetivos. Es necesario establecer directrices para utilizar la DC adecuadamente y asi expandir su conocimiento y utilizacion en paises hispanoparlantes. El Comite Nacional de Dieta Cetogenica, dependiente de la Sociedad Argentina de Neurologia Infantil, elaboro este consenso para estandarizar el uso de la DC basandose en la bibliografia publicada y la experiencia clinica. El grupo esta formado por neuropediatras, medicos nutricionistas y licenciadas en nutricion de cinco provincias de Argentina pertenecientes a 10 centros que aplican la DC como tratamiento de la epilepsia refractaria. Desarrollo. Se exponen temas tales como la seleccion del paciente, el asesoramiento a la familia antes del tratamiento, las interacciones de la DC con la medicacion anticonvulsionante, los suplementos, el control de efectos adversos y la retirada de dicha dieta. Conclusiones. La DC es un tratamiento util para los pacientes pediatricos con epilepsia intratable. Es fundamental la educacion y colaboracion del paciente y la familia. El tratamiento debe llevarlo a cabo un equipo interdisciplinar experimentado, siguiendo un protocolo. La formacion de un grupo nacional interdisciplinar, y la publicacion de este consenso, ofrece la posibilidad de orientar a nuevos centros en su implantacion.

    We prospectively analyzed EEGs from participants in the ongoing NIH Rare Diseases Clinical Research Network Angelman Syndrome Natural History Study. Of the one-hundred-sixty enrolled patients (2006-2010), 115 had complete data (58 boys, median age 3.6 years). Distinct EEG findings were intermittent rhythmic delta waves (83.5%), interictal epileptiform discharges (74.2%), intermittent rhythmic theta waves (43.5%), and posterior rhythm slowing (43.5%). Centro-occipital and centro-temporal delta waves decreased with age (p=0.01, p=0.03). There were no specific correlations between EEG patterns and genotypes. A classification tree allowed the prediction of deletions class-1 (5.9 Mb) in patients with intermittent theta waves in <50% of EEG and interictal epileptiform abnormalities; UPD, UBE3A mutation or imprinting defects in patients with intermittent theta in <50% of EEG without interictal epileptiform abnormalities; deletions class-2 (5.0 Mb) in patients with >50% theta and normal posterior rhythm; atypical deletions in patients with >50% theta but abnormal posterior rhythm. EEG patterns are important biomarkers in Angelman syndrome and may suggest the underlying genetic etiology.

    Assessing telomere length is of vital importance since telomere length is closely related with several fatal diseases such as atherosclerosis and cancer. Here, we present a strategy to assess/measure telomere length, that is, surface enhanced Raman scattering (SERS) based in situ hybridization (SISH). The SISH method uses two kinds of SERS nanoprobes to hybridize in situ with telomeres and centromeres, respectively. The telomere specific SERS nanoprobe is called the Telo-probe, while the centromere specific SERS nanoprobe is called the Centro-probe. They are composed of metal nanoparticles (NPs), Raman reporter molecules and specially designed DNA strands. With longer telomeres, more Telo-probes will hybridize with them, resulting in a stronger SERS signal. To exclude possible influence of the SERS intensity by external factors (such as the nanoprobe concentration, the cell number or different batches of nanoprobes), centromeres are used as the inner control, which can be recognized by Centro-probes. Telomere length is evaluated using a redefined telomere-to-centromere ratio (T/C ratio). The calculation method for T/C ratio in SISH method is more reliable than that in fluorescent in situ hybridization (FISH). In addition, unlike FISH method, the SISH method is insensitive to autofluorescence. Moreover, SISH method can be used to analyze single telomeres. These features make SISH an excellent alternative strategy for telomere length measurement.

    The Mexican Seismic Network (Red Sísmica Mexicana) was created to give sufficient information and opportune to make decisions in order to mitigate seismic and tsunami risk. This was a Mexican government initiative headed by CENAPRED (National Disaster Prevention Center) who made an effort to integrated academic institutions and civil agencies to work together through a collaboration agreement. This network is supported by Universidad National Autónoma de México (UNAM) and its seismic networks (Broad Band and Strong Motion), the Centro de Instrumentación y Registro Sismico (CIRES) with its Earthquake Early Warning System that covers the Guerrero Gap and Oaxaca earthquakes, The Centro de Investigación Científica y de Educación Superior de Ensenada (CICESE) with the support of its expertise in tsunami observation and the Secretaria de Marina (SEMAR) to monitor the sea level and operate the Mexican Tsunami Warning Center. The institutions involved in this scope have the compromise to interchange and share the data and advice to the Civil Protection authorities.

    The emotions people feel can be simulated internally based on emotional situational contexts. In the present study, we assessed the behavioral and neuroelectric effects of seeing an unexpected emotional facial expression. We investigated the correct answer rate, response times and Event-Related Potential (ERP) effects during an incongruence paradigm between emotional faces and sentential contexts allowing emotional inferences. Most of the 36 healthy participants were recruited from a larger population (1 463 subjects), based on their scores on the Empathy Questionnaire (EQ). Regression analyses were conducted on these ratings using EQ factors as predictors (cognitive empathy, emotional reactivity and social skills). Recognition of pragmatic emotional incongruence was less accurate (P < .05) and slower (P < .05) than recognition of congruence. The incongruence effect on response times was inversely predicted by social skills. A significant N400 incongruence effect was found at the centro-parietal (P < .001) and centro-posterior midline (P < .01) electrodes. Cognitive empathy predicted the incongruence effect in the left occipital region, in the N400 time window. Finally, incongruence effects were also found on the LPP wave, in frontal midline and dorso-frontal regions, (P < .05), with no modulation by empathy. Processing pragmatic emotional incongruence is more cognitively demanding than congruence (as reflected by both behavioral and ERP data). This processing shows modulation by personality factors at the behavioral (through self-reported social skills) and neuroelectric levels (through self-reported cognitive empathy).

  8. Second order nonlinearity in Si by inhomogeneous strain and electric fields

    NASA Astrophysics Data System (ADS)

    2015-08-01

    The lack of a dipolar second order susceptibility (χ(2)) in silicon due to its centro-symmetric diamond lattice usually inhibits efficient second order nonlinear optical processes in the silicon bulk. Depositing stressed silicon nitride layers or growing a thermal oxide layer introduces an inhomogeneous strain into the silicon lattice and breaks the centro-symmetry of its crystal structure thereby creating a χ(2). This causes enhanced second harmonic generation and was observed in reflection and transmission measurements for wavelengths in the infrared. However strain is not the only means to break the structures symmetry. Fixed charges at the silicon nitride/silicon interface cause a high electric field close to the silicon interface which causes electric-field-induced-second-harmonic (EFISH) contributions too. The combination of both effects leads to χ(2) values which are estimated to be of the order as classic χ(2) materials like KDP or LiNiO3. This paves the way for the exploitation of other second order nonlinear processes in the area of silicon photonics and is an example how fundamental optical properties of materials can be altered by strain.

    Introducción: Los tratamientos antineoplasicos orales presentan ventajas en cuanto a coste, comodidad y mejora potencial en la calidad de vida respecto al tratamiento endovenoso, pero es mas dificil controlar la adherencia y monitorizar los efectos adversos. El objetivo de este estudio fue conocer la adherencia real en pacientes con antineoplasicos orales en nuestro centro, analizar la influencia de las caracteristicas del paciente y del tratamiento, identificar motivos de no adherencia, oportunidades de mejora en la atencion farmaceutica y evaluar la posible relacion adherencia y respuesta al tratamiento. Método: estudio prospectivo observacional de cuatro meses de duracion, en los pacientes con tratamiento antineoplasico oral dispensado desde la consulta de farmacia oncologica. Para la recogida de datos se utilizaron: orden medica, historia clinica y visita con entrevistas al paciente. Resultados: Se evaluaron un total de 141 pacientes. Un 72% se considero totalmente adherente, mientras que en un 28% se detecto algun tipo de no adherencia. El tiempo desde el diagnostico y la presencia de efectos adversos fueron las variables que afectaron a la adherencia. No se pudo demostrar relacion entre adherencia y respuesta al tratamiento. Conclusiones: La adherencia al tratamiento antineoplasico oral en nuestro centro fue del 72%, identificando oportunidades de mejora en la atencion farmaceutica dirigidas a prevenir los efectos adversos y a potenciar la adherencia de nuestros pacientes.

    We used event-related brain potentials to explore the impact of mental perspective taking on processes of aesthetic appreciation of visual art. Participants (non-experts) were first presented with information about the life and attitudes of a fictitious artist. Subsequently, they were cued trial-wise to make an aesthetic judgment regarding an image depicting a piece of abstract art either from their own perspective or from the imagined perspective of the fictitious artist [i.e., theory of mind (ToM) condition]. Positive self-referential judgments were made more quickly and negative self-referential judgments were made more slowly than the corresponding judgments from the imagined perspective. Event-related potential analyses revealed significant differences between the two tasks both within the preparation period (i.e., during the cue-stimulus interval) and within the stimulus presentation period. For the ToM condition we observed a relative centro-parietal negativity during the preparation period (700–330 ms preceding picture onset) and a relative centro-parietal positivity during the stimulus presentation period (700–1100 ms after stimulus onset). These findings suggest that different subprocesses are involved in aesthetic appreciation and judgment of visual abstract art from one’s own vs. from another person’s perspective. PMID:26617506

    The brain activity associated with processing numerical end values has received limited research attention. The present study explored the neural correlates associated with processing semantic end values under conditions of automatic number processing. Event-related potentials (ERPs) were recorded while participants performed the numerical Stroop task, in which they were asked to compare the physical size of pairs of numbers, while ignoring their numerical values. The smallest end value in the set, which is a task irrelevant factor, was manipulated between participant groups. We focused on the processing of the lower end values of 0 and 1 because these numbers were found to be automatically tagged as the “smallest.” Behavioral results showed that the size congruity effect was modulated by the presence of the smallest end value in the pair. ERP data revealed a spatially extended centro-parieto-occipital P3 that was enhanced for congruent versus incongruent trials. Importantly, over centro-parietal sites, the P3 congruity effect (congruent minus incongruent) was larger for pairs containing the smallest end value than for pairs containing non-smallest values. These differences in the congruency effect were localized to the precuneus. The presence of an end value within the pair also modulated P3 latency. Our results provide the first neural evidence for the encoding of numerical end values. They further demonstrate that the use of end values as anchors is a primary aspect of processing symbolic numerical information. PMID:26640436

    It is thought that the proposed new family of multi-functional materials, namely, the ferroelectric thermoelectrics may exhibit enhanced functionalities due to the coupling of the thermoelectric parameters with ferroelectric polarization in solids. Therefore, the ferroelectric thermoelectrics are expected to be of immense technological and fundamental significance. As a first step towards this direction, it is most important to identify the existing high performance thermoelectric materials exhibiting ferroelectricity. Herein, through the direct measurement of local polarization switching, we show that the recently discovered thermoelectric semiconductor AgSbSe{sub 2} has local ferroelectric ordering. Using piezo-response force microscopy, we demonstrate the existence of nanometer scale ferroelectric domains that can be switched by external electric field. These observations are intriguing as AgSbSe{sub 2} crystalizes in cubic rock-salt structure with centro-symmetric space group (Fm–3m), and therefore, no ferroelectricity is expected. However, from high resolution transmission electron microscopy measurement, we found the evidence of local superstructure formation which, we believe, leads to local distortion of the centro-symmetric arrangement in AgSbSe{sub 2} and gives rise to the observed ferroelectricity. Stereochemically active 5S{sup 2} lone-pair of Sb may also give rise to local structural distortion thereby creating ferroelectricity in AgSbSe{sub 2}.

    Ritual use of ayahuasca, an amazonian Amerindian medicine turned sacrament in syncretic religions in Brazil, is rapidly growing around the world. Because of this internationalization, a comprehensive understanding of the pharmacological mechanisms of action of the brew and the neural correlates of the modified states of consciousness it induces is important. Employing a combination of electroencephalogram (EEG) recordings and quantification of ayahuasca's compounds and their metabolites in the systemic circulation we found ayahuasca to induce a biphasic effect in the brain. This effect was composed of reduced power in the alpha band (8–13 Hz) after 50 minutes from ingestion of the brew and increased slow- and fast-gamma power (30–50 and 50–100 Hz, respectively) between 75 and 125 minutes. Alpha power reductions were mostly located at left parieto-occipital cortex, slow-gamma power increase was observed at left centro-parieto-occipital, left fronto-temporal and right frontal cortices while fast-gamma increases were significant at left centro-parieto-occipital, left fronto-temporal, right frontal and right parieto-occipital cortices. These effects were significantly associated with circulating levels of ayahuasca’s chemical compounds, mostly N,N-dimethyltryptamine (DMT), harmine, harmaline and tetrahydroharmine and some of their metabolites. An interpretation based on a cognitive and emotional framework relevant to the ritual use of ayahuasca, as well as it's potential therapeutic effects is offered. PMID:26421727

    We studied the wood anatomy of 29 species belonging to 10 genera of the tribe Detarieae, subfamily Caesalpinioideae and compare them with tribe Caesalpinieae. Detarieae is the largest of four tribes of Caesalpinioideae, with 84 genera, only eleven occur in Venezuela with species of timber importance. The specimens were collected in Venezuela and include wood samples from the collection of the Laboratorio de Anatomía de Maderas de la Facultad de Ciencias Forestales y Ambientales de la Universidad de Los Andes, Venezuela, and of the Forest Products Laboratory of the USDA Forest Service in Madison, Wisconsin, USA. The terminology and methodology used followed the IAWA List of Microscopic Features for Hardwood Identification of the IAWA Committee, 1989. Measurements from each specimen were averaged (vessel diameters, vessel element lengths, intervessels pit size, fibre lengths and ray height). The species of Detarieae can be separated using a combination of diagnostic features. Wood characters that provide the most important diagnosis and may be used in systematics of Detarieae include: intercellular axial canals, rays heterocellular, rays exclusively or predominantly uniseriate, prismatic crystals common in ray cells, irregular storied structure and fibre wall thickness. For comparative anatomy between Detarieae and Caesalpinieae: intercellular axial canals, heterocellular rays, rays exclusively or predominantly uniseriate, prismatic crystals common in ray cells (in Detarieae) and regular storied structure, fibres septate, fibre wall thick or very thick, rays homocellular, multiseriate rays and silica bodies (in Caesalpinieae). Axial parenchyma is typically a good diagnostic feature for Leguminosae, but not for Detarieae and Caesalpinieae comparisons.

    The ovarian activity of Agouti paca was characterized by hormonal profiles and ovarian structures. Samples of blood were taken from eight females (seven adults and one juvenile) at the breeding grounds of the Facultad de Medicina Veterinaria y Zootecnia in Yucatśn, Mexico. Sampling lasted approximately two months and was done every three and six days. Blood was collected from anesthetized animals, and the levels of progesterone (P4) and 17 beta estradiol (E2) were analized by radioimmunoassay technique. Macroscopic and microscopic analyses were carried out in ovaries of dead animals. The estrous cycle lasted 29+/-8.4 days, levels of 1.61+/-0.65 ng/ml for P4 and 39+/-24 pg/ml for E2 were observed for a follicular phase, 6.18+/-3.70 ng/ml and 29+/-16 pg/ml for P4 and E2 respectively in the luteal phase. Statistically significant differences were found between phases for P4 but not for E2. The presence of extragonadal steroids with levels of P4 of 1.9+/-0.77 ng/ml and E2 of 22+/-17 pg/ml were observed, which are not produced by the effects of managing stress. The changes in the levels of P4 during the cycle are indicators of luteal activity, with the intersticial tissue acting probably as active steroids-producing gland. Follicular growth was observed during the entire cycle.

    The orthotopic rat liver transplant model is a widely used technique in transplantation research. It has many advantages over other animal transplant models because of its availability and low cost. However, it must be emphasized that success with the rat model requires thorough training. The aim of this paper is to describe the microsurgical technique involved in 60 rat liver transplants and to discuss the complications and their treatments. Forty-nine liver transplants were performed at the Experimental Laboratory of the University Hospital, Ontario, Canada (ELUH) and 11 were performed at the Laboratorio de Trasplante de Organos de la Facultad de Ciencias Médicas de La Plata, Buenos Aires. Argentina (LTO). Among the transplants performed at the ELUH, the observed complications were haemorrhage (n = 4), pneumothorax (n = 1), anastomotic failure (n = 15), bile leak (n = 3), and bile duct necrosis (n = 9). The remaining 17 rats at the ELUH were healthy at day 7 after surgery. Animal survival immediately postop, at 24 hours postop and at 7 days postop was achieved with the 9th, 20th and 21st transplants respectively. At the LTO, 3 rats died as a result of anaesthetic complications. Seven-day animal survival was achieved with the 11th transplant. We beleive that the description of the orthotopic rat liver transplantation technique, as well as the discussion regarding complications and their management, can be useful for researchers interested in performing liver transplantation in rats.

    ABSTRACT OBJECTIVE To describe the constitution and operation of a voluntary interruption of pregnancy team of a university hospital, from the outlook of the mental health team. METHODS In this case study, the following aspects were analyzed: 1) historical background; 2) implementation of Law 18,897 of October 22, 2012; and 3) functioning of the program at the Hospital de Clínicas of the Facultad de Medicina (Universidad de la República, Uruguay), taking into account three dimensions: structure, process, and results. RESULTS Between December 2012 and November 2013, a total of 6,676 voluntary interruptions of pregnancy were reported in Uruguay; out of these, 80 were conducted at the Hospital de Clínicas. The patients’ demographic data agreed with those reported at the national level: Of the total patients, 81.0% were aged over 19 years; 6.2% decided to continue with the pregnancy; and only 70.0% attended the subsequent control and received advice on contraception. CONCLUSIONS In its implementation year in Uruguay, we can assess the experience as positive from the point of view of women’s health. Our experience as a mental health team at the Hospital de Clínicas, inserted into the multidisciplinary voluntary interruption of pregnancy team, is in the process of assessment and reformulation of practices.

    Introduccion. Actualmente, cuando reflexionamos sobre cual es la estructura mas relevante del encefalo humano invariablemente pensamos en las regiones anteriores de la corteza cerebral, concretamente en la corteza prefrontal. Si bien este ha sido el dogma predominante a lo largo de mas de 150 años, investigadores de reconocido prestigio han cuestionado abiertamente tal supuesto. Desarrollo. A caballo entre los siglos XIX y XX, diversos investigadores consideraron que las regiones corticales posteriores son la sede neuroanatomica de las mas altas facultades intelectuales. Entre todos ellos destaco, por la elaboracion de sus propuestas e impacto en la comunidad cientifica, el neuroanatomista aleman Paul Emil Flechsig (1847-1929). Wilder Graves Penfield (1891-1976) fue otro detractor del dogma que considera la corteza prefrontal el sustrato anatomico de los procesos mentales mas complejos y sublimes del ser humano. A mediados del siglo XX, Penfield mantuvo la hipotesis de la existencia de lo que denomino el sistema de integracion centrencefalico, responsable del nivel mas elevado de integracion del sistema nervioso central. Conclusiones. Las concepciones corticocentricas otorgan el preciado cetro de 'estructura mas importante del encefalo' a la corteza prefrontal. Sin embargo, no han faltado propuestas alternativas que, con mayor o menor exito, han intentado arrebatarselo en favor de otras estructuras encefalicas.

    Superconductor/ferromagnet heterostructures are currently a subject of strong research due to novel phenomena resulting from the proximity effect. Among the most investigated ones are the oscillations of the critical temperature as function of the ferromagnet thickness. The oscillatory behavior of Tc is theoretically explained as to be result of the generation of the FFLO (Fulde-Ferrel-Larkin-Ovchinnikov) state of Cooper pairs under the presence of the exchange field of the ferromagnet. With the advancement of experimental techniques for S/F bilayers growth new questions regarding the effect of the interface transparency can to be addressed. For instance the influence of the interface roughness on the proximity effect. For studying this phenomenon Nb/Co and Nb/Cu/Co samples were sputtered on SiO2 substrates with different roughness. Characterization of these samples show a significant variation of Tc with the interface roughness. This results point towards a possible relationship between transparency and roughness of the interface. Proyecto Semilla Facultad de Ciencias Universidad de los Andes.

    During a study on the helminth fauna of Liophis anomalus specimens deposited in the Reptile Collection of the Secci6n Zoología Vertebrados, Facultad de Ciencias, Uruguay, a new genus of Opisthogoniminae was found. Paracotyletrema n. gen. is described from the buccal cavity and esophagus of specimens from Departamento de Flores, Uruguay. This new genus differs from the other 2 Opisthogoniminae, Opisthogonimus and Westella, by having much smaller body size; maximum width at level of posterior end of oral sucker; oral sucker length more than one-fourth of body length; oral sucker and acetabulum separated by a distance of about the diameter of pharynx; cirrus pouch length more than half of body length; and testes in completely coincident zones. The type and only species, Paracotyletrema poncedeleoni n. gen., n. sp., is defined by the following diagnostic characters: mean oral sucker length one-third to one-half of body length; cirrus pouch of about body length, contorted, mainly acetabular; large, round testes in nearly adjacent fields, and an ovary nearly adjacent to right testis. Besides the type locality, Paracotyletrema poncedeleoni has been found in L. anomalus specimens from the Departamentos of Artigas and Treinta y Tres; therefore, it has a widespread distribution in Uruguay.

    In Facultad de Ciencias Exactas y Naturales,Universidad de Buenos Aires there is a service called Servicio de Identificación de Hongos Tóxicos, directed by researchers of the Program of Medicinal Plants and Fungi Involved in Biological Degradation (PROPLAME-PRHIDEB, CONICET) that assist hospitals and other health establishments, identifying the different samples of fungi and providing information about their toxicity, so that patients can receive the correct treatment. The objective of the present study was to analyze all the cases received from 1985 to 2012. This analysis permitted the confection of a table identifying the most common toxic species. The information gathered revealed that 47% of the patients were under 18 years of age and had eaten basidiomes; the remaining 53% were adults who insisted that they were able to distinguish edible from toxic mushrooms. Chlorophyllum molybdites turned out to be the main cause of fungal intoxication in Buenos Aires, which is commonly confused with Macrolepiota procera, an edible mushroom. In the second place Amanita phalloides was registered, an agaric known to cause severe symptoms after a long period of latency (6-10 hours), and which can lead to hepatic failure even requiring a transplant to prevent severe internal injuries or even death, is not early and correctly treated.

    Merlo, D. C.

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

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

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

    Supernumerary teeth (ST) are a not uncommon developmental anomaly which appears in 0.3 to 3.8 percent of the population. We studied the corresponding radiographs from 2241 patients, both sexes who seeked dental attention at the Outpatient Clinic of the División de Estudios de Posgrado e Investigación, Facultad de Odontología, UNAM in Mexico City. Of them, we found 72 patients (3.2%) with 102 ST. Of the 72 patients, 39 were males (54.2%) and 33 females (45.8%). Mesiodens was the most common ST (48.6%), followed by supernumerary premolars (26.4%), supernumerary laterals (11.1%) and fourth molars (9.7%). This series includes cases with one, two and three ST and one case comprising 10 ST. Our results suggest that frequency of ST in the population studied differs in some aspects with previously reported series and that frequency of ST shows different rates depending the population studied. As our results demonstrate, it is encouraged the need to have panoramic radiographs of all patients attended in dental offices, clinics and schools of Dentistry in order to detect and diagnose undiscovered pathologies.

    The micronucleus (MN) assay evaluates the effects of low doses of genotoxic carcinogens and can detect structural lesions that survive mitotic cycles. The objective of this study was to determine both the genotoxicity of nickel (Ni) in buccal epithelial cells and the urinary excretion of Ni in children with metal crowns. This was a prospective longitudinal study based on 37 patients selected at the Facultad de Odontología de la Universidad Autónoma de Coahuila. MN assays were performed using buccal cells from the 37 patients, and Ni levels were determined from urine samples using inductively coupled plasma mass spectrometry at 1 (basal value), 15, and 45 days following the placement of crowns in each patient. Ni urinary excretion levels increased from 2.12 ± 1.23 to 3.86 ± 2.96 mg Ni/g creatinine (P < 0.05) and the frequency of exposed micronuclei increased from 4.67 ± 0.15 to 6.78 ± 0.167/1000 cells (P < 0.05) between 1 and 45 days post-crown placement. These results suggest that odontological exposure to metal crowns results in genotoxic damage at the cellular level of the oral mucosa and an increase in the urinary excretion of Ni within 45 days of exposure.

    Introduccion. La migraña puede cursar con sintomas autonomicos craneales propios de las cefaleas trigeminoautonomicas, lo que plantea dificultades en el diagnostico. Objetivo. Describir una serie de diez pacientes con edema palpebral asociado a la migraña. Pacientes y metodos. Diez pacientes atendidos en la consulta de cefaleas de tres hospitales (nueve mujeres, un varon; edad: 26-53 años), con edema palpebral recurrente asociado a la migraña. Resultados. Segun los criterios diagnosticos de la Clasificacion Internacional de las Cefaleas (ICHD-III, version beta), ocho pacientes presentaban migraña sin aura, una tenia migraña con aura y otra, migraña cronica. El edema palpebral aparecia durante las crisis de migraña mas intensas, y tenia mayor duracion que la cefalea. Se descartaron causas farmacologicas o sistemicas del edema en todos los casos. Otros sintomas autonomicos asociados fueron la inyeccion conjuntival (n = 3), el lagrimeo (n = 2) y la rinorrea (n = 1). Tanto el dolor como el edema asociado respondieron a los tratamientos sintomaticos y preventivos de la migraña. Conclusiones. El edema palpebral es un posible acompañante de la migraña. Aparece en algunos pacientes con los episodios de mayor intensidad, y responde al tratamiento sintomatico y preventivo de la migraña.

    Introduccion. El trastorno por deficit de atencion/hiperactividad (TDAH) tiene una prevalencia del 3-7% de la poblacion en edad escolar y cursa con problemas academicos y disfunciones ejecutivas. Objetivo. Estudiar la relacion entre el diagnostico del TDAH por medio de los criterios del Manual diagnostico y estadistico de los trastornos mentales, quinta edicion (DSM-5), y la evaluacion neuropsicologica de las funciones ejecutivas. Sujetos y metodos. Se evaluo a 50 sujetos, 12 mujeres y 38 varones, entre 8 y 10 años. Para evaluar el control inhibitorio se utilizo el Continuous Performance Test (CPT) y el test de Stroop; para la inteligencia y la memoria de trabajo, la escala de inteligencia de Wechsler para niños-IV; y para la atencion, el CPT y el Selective Attention Test. Resultados. No habia diferencias significativas entre ambos subtipos de TDAH en cuanto a la memoria de trabajo. Las niñas presentaban mejores habilidades en la tarea de flexibilidad cognitiva que los niños, y los sujetos diagnosticados de TDAH combinado presentaban mayores dificultades en el control inhibitorio. Conclusiones. Confirmamos que las definiciones del TDAH en el DSM-5 son imprecisas. Son una escasa enumeracion de sintomas clinicos del trastorno, sin definir con claridad criterios propios de el. Por lo tanto, la definicion del trastorno se realiza por la evaluacion especifica de la atencion y de los mecanismos de control inhibitorio y, por ello, es necesaria una evaluacion neuropsicologica de las funciones cerebrales superiores.

  15. Dinámica de planetas extrasolares resonantes

    NASA Astrophysics Data System (ADS)

    Beauge, C.

    Actualmente se han detectado 117 planetas alrededor de estrellas de Secuencia Principal, incluyendo 12 sistemas planetarios, cada uno con dos o tres miembros. De estos últimos, ocho poseen planetas en órbitas próximas y sus perturbaciones gravitacionales se convierten en un factor fundamental para la estabilidad orbital del sistema. Todos se encuentran en configuraciones resonantes, desde la conmensurabilidad de movimientos 2/1 de Gliese 876, hasta la resonancia secular de Ups And. En esta presentación analizamos varios aspectos de la dinámica resonante de los planetas extrasolares, incluyendo la existencia de soluciones de equilibrio, construcción de modelos analógicos y métodos para la determinación de masas individuales. También discutimos por qué las resonancias son tan frecuentes en estos sistemas, comparado con nuestro propio Sistema Solar. Por último, intentamos relacionar estos modelos con la hipótesis de migración planetaria, buscando límites en su extensión y en los posibles mecanismos que le dieron origen.

  16. El nuevo panorama de la Dinámica Galáctica

    NASA Astrophysics Data System (ADS)

    Pivovaroff, Michael James

    En general, la tendencia imperante en Dinámica Galáctica ha sido considerar que los movimientos estelares son básicamente regulares y que el caos no tiene mayor relevancia en los sistemas estelares. Sin embargo, en el último lustro se vienen acumulando pruebas de la importancia del movimiento caótico en ciertos sistemas estelares que existen en la naturaleza. Por una parte, sobre todo el grupo de David Merritt, lo ha mostrado en los casos de galaxias elípticas con concentraciones centrales de materia; por otra parte, en nuestro propio grupo, lo hemos mostrado para el caso de los satélites galácticos. Las consecuencias de estos hallazgos son tanto de tipo técnico, por la necesidad de construir modelos que contengan órbitas caóticas, como astrofísico, por los efectos del caos sobre la estacionariedad y evolución de los sistemas estelares en los que se presenta.

    Objetivo: cuantificar y analizar las causas por las que los pacientes oncológicos acuden al Servicio de Urgencias y analizar el uso de factores estimulantes de colonias para la profilaxis o el tratamiento de la neutropenia febril. Método: estudio retrospectivo de seis meses del año 2012. Se incluyeron pacientes adultos con tumor sólido y tratamiento activo atendidos por oncólogos en el Servicio de Urgencias. Resultados: se incluyeron 83 pacientes. Respecto al motivo de consulta: en el 63% es causa tumoral, 31% toxicidad postquimioterapia y 6% otras causas. En los que acuden por toxicidad, el 65% presentaron fiebre o síntomas de infección, el 50% dolor y el 42% neutropenia febril. La profilaxis y el tratamiento de la neutropenia febril con filgrastim siguieron las recomendaciones. Conclusiones: la mayor parte de los episodios oncológicos en Urgencias son debidos al propio proceso tumoral. Algunos problemas importantes son el manejo del dolor, la fiebre y la neutropenia.

    Se llevó a cabo una revisión minuciosa del cálculo de funciones de partición atómicas de átomos livianos, en estados neutro y una vez ionizados, partiendo del Hidrógeno y llegando al Sodio, incluyendo también al K I y el Ca II. Al respecto, se realizó una investigación exhaustiva de referencias bibliográficas existentes hasta el presente, las cuales fueron cotejadas con cálculos propios llevados a cabo mediante el procedimiento de depresión del contínuo (0.001 a 0.5 eV). Nuestros resultados muestran un muy buen acuerdo con las expresiones interpolatorias de Traving et al (1966), al presente, la referencia más completa en cuanto a especies atómicas consideradas. Puntualizamos, además, ciertas deficiencias de estas relaciones de ajuste para decrementos del potencial de ionización altos (Δ χ >= 0.5) eV).

    2009-01-01

    El hospital psiquiátrico se ha constituido como un lugar donde se posibilita legitimar la exclusión y la radicalidad de ese otro “que no es igual”, como es el caso del sujeto que atenta contra su propia vida. En consecuencia, el intento de suicidio desde el pensamiento foucaultiano, es una resistencia que desmantela la estructura de dominación a través de un acto de poder, el cual se ejerce sobre el propio cuerpo. Así, la intención de este texto es mostrar que la relación Otro-otro es un lugar en la estructura subjetiva, que se deposita en la institución psiquiátrica, la cual representa el poder, la ley, y es aquello a lo que se le quiere agredir, resistir, abatir con un intento de suicidio. Para demostrar como se materializan estos hechos, se exponen los testimonios de tres adolescentes atendidas en un hospital psiquiátrico por intentos suicidas, en los cuales se señalan los diferentes significados que le atribuyen a la institución psiquiátrica en tanto que representa un Otro en sus actos autoinfligidos.

    Introduccion. La moralidad es el conjunto de normas y valores que guian la conducta. Se mantienen en muy diferentes culturas. Permiten alcanzar logros sociales que solo se entienden bajo el desarrollo moral, con un sentido de justicia que penetra toda accion humana. Las funciones morales, fruto del desarrollo evolutivo, asientan en circuitos neuronales propios. Objetivo. Describir su aparicion, puesta en marcha y mecanismos operativos en el cerebro normal. Desarrollo. Las respuestas morales, en lo esencial homogeneas, estan muy vinculadas al desarrollo emocional, tanto basico e individual (miedo o ira) como social (compasion o justicia). Aparecen a partir de los binomios emocionales placer/dolor y recompensa/castigo, que conducen al binomio moral basico bueno/malo. En su puesta en marcha intervienen la corteza prefrontal (ventromedial y dorsolateral), la corteza cingular anterior y el sulco temporal superior, que serian evaluativos y elaborativos, utilitaristas; tambien la insula, la amigdala y el hipotalamo, ejecutivos de las respuestas morales mas emocionales puras y rapidas. Asimismo, es importante el sistema de neuronas espejo (frontoparietal), que permite el aprendizaje motor y las conductas empaticas, con las que se vincula con la teoria de la mente. Conclusiones. El desarrollo del sentido moral y sus respuestas nos han permitido alcanzar una complejidad y convivencia social que redundan en beneficio de la especie e individuos. El conocimiento del funcionamiento moral esta influyendo tambien en territorios diversos de la neurocultura.

    di Sisto, R. P.; Orellana, R.

    El Observatorio de La Plata cuenta con un gran número de placas de asteroides y cometas obtenidas con el telescopio astrográfico, que cubren gran parte del cielo del hemisferio sur. En 1996 se recopilaron y clasificaron 2187 placas (Beca para estudiantes de la AAA 1996) de las cuales 2031 corresponden a asteroides. Los datos de cada placa se volcaron en una base de datos creada para facilitar su manejo y preservar la información. A partir de este trabajo se revisaron los MPC electrónicos y se identificaron aquellas placas de asteroides pertenecientes a nuestra base de datos cuyos resultados no fueron publicados en los mismos. De un total de 400 placas que no aparecían publicadas sobresalía un paquete constituído por 40 placas obtenidas en 1977. Estas últimas fueron reducidas utilizando las posiciones y movimientos propios de las estrellas de referencia obtenidas del catálogo SAO 2000 dadas para el sistema FK5. Las posiciones calculadas fueron enviadas y publicadas en los Minor Planet Circulars (MPC).

    Introduccion. La moralidad es el conjunto de normas y valores que guian la conducta. Se mantienen en muy diferentes culturas y permiten alcanzar altos logros sociales. Asientan en circuitos neuronales propios. Su lesion o alteracion funcional generara alteraciones o cambios en la conducta moral. Objetivo. Describir las disfunciones morales, su puesta en marcha y los mecanismos operativos en diferentes lesiones y patologias neurologicas. Desarrollo. Las patologias de la moralidad se deben a la lesion estructural de diferente grado (destructiva prefrontal; microscopica en amigdala/corteza prefrontal en las psicopatias), a la disfuncion de mediadores (hiperfuncion dopaminergica en trastornos de la conducta de parkinsonianos con algunos tratamientos o en toxicomanias) o a trastornos geneticos (mutaciones de COMT o MAO en ciertas sociopatias). Actuan por mecanismo excitatorio, inhibitorio o mixto en los circuitos morales emocionales (temporales) y cognitivos (prefrontales). Las topografias y mecanismos explican la diferente expresividad clinica. Conclusiones. El conocimiento de las alteraciones de la conducta moral refuerza los conocimientos anatomicos y fisiologicos de la moralidad en la poblacion sana. Es un factor que contribuye a la elucidacion de las variaciones eticas interculturales y al pujante desarrollo reciente de la neuroetica, que, por su complejidad, se beneficia de aportaciones de diversos territorios de la neurocultura.

    Introducción: La evaluación del desarrollo fetal y del peso al nacimiento es un objetivo prioritario en el ámbito de la epidemiología nutricional y de la salud pública. En la actualidad, la Organización Mundial de la Salud (OMS) no dispone de curvas específicas de peso al nacimiento para las distintas semanas gestacionales al considerar que las características socioeconómicas, ecológicas y étnicas de los distintos grupos humanos influyen en sus propios patrones de crecimiento. Objetivo: La presente investigación desarrolla las curvas percentilares de peso por edad gestacional para las poblaciones residentes en la provincia de Catamarca. Métodos: El procesamiento de los datos se llevó a cabo con el programa SPSS y para la posterior realización de las curvas percentilares se utilizó el programa LMS Chart Maker pro, a partir de un total de 22.576 nacimientos ocurridos entre 1994 y 2003. Discusión y conclusiones: Dichas curvas posibilitarán en el futuro una mejor valoración del desarrollo intrauterino y del peso de los recién nacidos en esta región del Noroeste de Argentina.

    Introduccion. El fracaso escolar, los trastornos de aprendizaje y las alteraciones de conducta son mas frecuentes en el niño epileptico que en la poblacion general. El objetivo de este trabajo es estudiar los diversos factores que pueden afectar al rendimiento escolar del niño con epilepsia. Desarrollo. Los aspectos que condicionan el fracaso escolar y las alteraciones de aprendizaje en el niño epileptico son muy heterogeneos, e incluyen factores propios de la epilepsia, factores de indole psicosocial y factores derivados del tratamiento antiepileptico. La edad de comienzo de la epilepsia, el tipo de sindrome epileptico, la etiologia de la epilepsia y la respuesta al tratamiento antiepileptico son algunos de los factores mas importantes. Todos los farmacos antiepilepticos disponibles pueden producir efectos adversos cognitivos, que son mas frecuentes en politerapia, con dosis totales altas y niveles sericos elevados. Conclusiones. Una buena valoracion de cada uno de los posibles factores implicados es fundamental para garantizar un mejor pronostico. El desarrollo de alteraciones en el rendimiento escolar en un niño con epilepsia debe conducir a una inmediata y exhaustiva evaluacion diagnostica y terapeutica.

    Estudio realizado desde el enfoque de la salutogénesis que pretende determinar el sentido de coherencia (SOC) en jóvenes presos de la Comunidad Valenciana en España y elaborar un mapa de activos para la salud dirigido a promover la salud en esta población. Se utilizó el test "SOC-13" y un cuestionario de preguntas abiertas elaboradoad hoc, el cual autocompletaron los internos de 18 a 22 años de edad, de los tres centros penitenciarios de la región. Participaron 124 jóvenes varones (ya que no había ninguna mujer) y se recogieron variables sociodemográficas y penitenciarias. En el análisis cuantitativo, las variables categóricas se expresaron como frecuencias absolutas y relativas; y las cuantitativas, mediante medias con intervalos de confianza (IC) al 95%. Se realizó un estudio comparativo bivariante, utilizando las siguientes pruebas: Studentt-test, análisis de variación (ANOVA), Wilcoxon y Ji-cuadrado. Del cuestionario de preguntas abiertas, se realizó un análisis cualitativo descriptivo temático de los activos identificados, clasificándolos en: internos (recursos personales, en relación con los demás y capacidad para realizar comportamientos saludables) y externos (personas, grupos, instituciones y espacios físicos, situados tanto dentro como fuera de prisión). La edad media fue de 21,1 años (IC 95%: 20,8-21,3); y el SOC de 52,4 (IC 95%: 50,5-54,3), de entre un valor mínimo de 13 y máximo de 91 para la prueba. Los internos del centro penitenciario que ofrecía más actividades escolares y deportivas obtuvieron una puntuación mayor en la dimensión de significatividad del SOC (p= 0,024), y los internos inmigrantes presentaron un SOC superior (p= 0,037) a los españoles, en los tres centros. Los jóvenes identificaron los activos internos que cualitativamente se vinculan con las dimensiones de comprensibilidad, manejabilidad y significatividad del SOC; y los activos externos, sobre todo los amigos, familiares y espacios relacionados con

    Introdução: A falência hepática aguda é uma doença rara associada a elevada morbilidade e mortalidade apesar do aumento da sobrevida devido ao transplante hepático. Em 2008, decorreu em Portugal uma reunião sobre esta patologia em pediatria, resultando num consenso de atuação que salientou a importância da abordagem multidisciplinar e referenciação precoce para um centro de transplantação hepática. Objetivos: Caracterizar as admissões por falência hepática aguda no Serviço de Cuidados Intensivos Pediátricos do centro português com transplante hepático pediátrico. Comparar resultados antes (A) e depois de 2008 (B). Material e Métodos: Estudo observacional retrospetivo de 20 anos (1994-2014). Critérios de inclusão: idade < 18 anos e falência hepática aguda (INR ≥ 2 sem resposta à vitamina K e necrose hepatocelular). Excluíram-se as crianças com doença hepática crónica. Resultados: Incluíram-se 50 crianças com idade mediana de 24,5 meses. A causa mais comum de falência hepática aguda abaixo dos 2 anos foi metabólica (34,6%) e acima infeciosa (29,2%). Foram submetidos a transplante hepático 46%, tendo sobrevivido 78%. A mortalidade global foi 34%. A mediana do tempo de referenciação foi 7 dias no período A (n = 35) e 2 no B (n = 15; p = 0,006). A mediana do risco de mortalidade prevista pelo PRISM foi 14,7% no período A e 6,5% no B (p = 0,019). A mortalidade foi 37% vs 26% no período A e B respetivamente (p = 0,474).Discussão e Conclusões: A mortalidade global foi sobreponível à de outros centros europeus, sendo o transplante hepático a opção terapêutica mais eficaz. Após 2008 o tempo de referenciação e a gravidade dos casos na admissão reduziram, ainda sem tradução significativa na mortalidade.

MÉTODOS: Estudio transversal multicéntrico en trabajadores sanitarios de hospitales de agudos, centros de asistencia primaria, centros sociosanitarios, centros de salud mental y un hospital geriátrico participantes en la campaña de vacunación antigripal del 2009. Se enviaron encuestas autocumplimentadas a todos los vacunados con VGE y/o VGA. RESULTADOS: De los 1123 vacunados con VGE se obtienen 527 encuestas válidas (46,9%) y de 461 vacunados con VGA se obtienen 242 encuestas (52,5%). De los trabajadores participantes 527 estaban vacunados sólo con VGE, 117 vacunados previamente con VGE y después VGA (VGE+VGA) y 125 sólo vacunados sólo con VGA. El 18,4% (IC 95% 15,1-21,7) del grupo VGE presentaron algún efecto adverso a la vacuna VGE; en el grupo VGE+VGA el 45,3% (IC 95% 36,3-54,3) presentó una reacción adversa al recibir la VGA, y en el grupo VGA fue el 46,4% (IC 95% 37,7-55,1). En todos los participantes el problema más frecuente fue una reacción local. Las mujeres presentan mayor reacción a VGA y VGE que los hombres. Para todas las edades la VGE es menos reactógena que VGA y que la combinación de ambas vacunas, con la excepción de los trabajadores menores de 29 años. CONCLUSIONES: La VGA es más reactógena que la VGE, sin diferencias por orden de administración. Se observan variaciones por sexo y edad, pero siempre con mayor reactogenicidad para la VGA.

    Introducción: a finales del siglo xx, no se conocía con precisión si la comida del comedor escolar contribuía adecuadamente a la dieta de la población infantil. Además, este servicio complementario no se contemplaba en el proyecto educativo del centro pese a considerarse fundamental en todas sus dimensiones.Objetivo: describir el origen y desarrollo del programa de comedores escolares de la Comunidad de Madrid (CM) en 15 años desde su implantación.Métodos: se elaboró una normativa a cumplir por las empresas de restauración, y que contemplaba aspectos nutricionales y de composición y variedad de los menús, que se utilizó en los concursos para acceder a la prestación del servicio de comedor escolar, publicados en los años 2001, 2002, 2005, 2009 y 2013. Además se realizaron visitas acreditadas a los centros sin previo aviso para verifi car el cumplimiento de la documentación aportada durante el concurso.Resultados: los criterios más actuales sobre programación y elaboración de menús escolares se recogen en el Pliego de Prescripciones Técnicas del año 2013 (C-504/001-2013). Un 92% de las empresas de restauración superaron los cinco concursos habidos en los 15 años de funcionamiento. Hasta el año 2014, se han realizado 755 visitas, revisándose un total de 574 centros.Conclusiones: el programa de comedores escolares de la CM, desde su implementación pionera en España, ha contribuido a la mejora del servicio complementario de comedor. En estos años se han ido incluyendo nuevos requisitos dietéticos y nutricionales que han logrado menús cada vez más ajustados a las recomendaciones de la población escolar.

    OBJETIVOS: Elaborar una propuesta sistematizada de medidas preventivas dirigida a factores personales y laborales asociados a la ocurrencia de accidentes de trabajo mortales (ATM) de naturaleza traumática, y valorar la utilidad de dicho procedimiento. MÉTODOS: El proceso se basa en la adaptación de la matriz de Haddon (dimensiones temporal, nivel de acción y colectivos específicos), determinando sus componentes a partir de los resultados de una investigación etiológica previa sobre factores asociados a los ATM. Los contenidos de las celdas de la matriz se completan mediante la identificación de las correspondientes medidas preventivas en la literatura científica. RESULTADOS: La matriz consta de las filas pre-lesión, lesión y post-lesión (dimensión temporal); las columnas trabajador, agente, centro de trabajo y entorno social (nivel de acción); y los colectivos específicos, definidos por actividad económica, género, edad, temporalidad y trabajo o centro no habituales. Las medidas propuestas incluyen la formación y el diseño de procedimientos seguros de trabajo en el nivel del trabajador, los elementos de protección pasiva en el nivel del agente productor de la lesión, la organización del espacio y las condiciones ambientales en el centro de trabajo, y la efectividad de los sistemas de prevención y atención de urgencia en el entorno social. CONCLUSIONES: La utilización y adaptación de la matriz de Haddon, a partir de resultados previos en la investigación etiológica de los ATM permite identificar de manera sistemática medidas preventivas dirigidas a los correspondientes factores de riesgo identificados, lo que puede ayudar a priorizar y seleccionar las acciones preventivas más adecuadas.

Se valoró el aporte energético y nutricional mediante el programa Dietowin® y el método de pesada.Resultados: las frutas y verduras fueron deficitarias en la mayoría de los menús, y excesivas la carne, patatas, pasta y arroz. Se observó una escasa variedad de recetas por grupo de alimentos y no se daba una información completa del menú. Sin embargo, la variedad de procesos culinarios y la rotación de alimentos fueron adecuadas. Aunque la energía y el aporte de carbohidratos (~55%) se ajustaban a las necesidades, se observó un aporte excesivo de proteínas (~19%) y deficiente de lípidos (< 30%), sobre todo de grasas insaturadas. Respecto a los micronutrientes,solo vitamina C, E y calcio estaban por debajo de lo recomendado.Conclusiones: los centros de educación infantil están haciendo un gran esfuerzo por cumplir las recomendaciones nutricionales, pero todavía deben disminuir el aporte proteico y aumentar las grasas insaturadas de la dieta. Además, deben fomentar la oferta de frutas y verduras, ampliar la variedad de recetas, dar mayor información y disminuir el aporte de alimentos cárnicos.

    We measured changes in key soil processes and the fluxes of CO2, CH4 and N2O associated with the conversion of tropical rainforest to pasture in Rondonia, a state in the southwest Amazon that has experienced rapid deforestation, primarily for cattle ranching, since the late 1970s. These measurements provide a comprehensive quantitative picture of the nature of surface soil element stocks, C and nutrient dynamics, and trace gas fluxes between soils and the atmosphere during the entire sequence of land-use change from the initial cutting and burning of native forest, through planting and establishment of pasture grass and ending with very old continuously-pastured land. All of our work is done in cooperation with Brazilian scientists at the Centro de Energia Nuclear na Agricultura (CENA) through an extant official bi-lateral agreement between the Marine Biological Laboratory and the University of Sao Paulo, CENA's parent institution.

  12. The effect of yield strength and ductility to fatigue damage

    Yeh, H. Y.

    1973-01-01

    The cumulative damage of aluminium alloys with different yield strength and various ductility due to seismic loads was studied. The responses of an idealized beam with a centered mass at one end and fixed at the other end to El Centro's and Taft's earthquakes are computed by assuming that the alloys are perfectly elastoplastic materials and by using numerical technique. Consequently, the corresponding residual plastic strain can be obtained from the stress-strain relationship. The revised Palmgren-Miner cumulative damage theorem is utilized to calculate the fatigue damage. The numerical results show that in certain cases, the high ductility materials are more resistant to seismic loads than the high yield strength materials. The results also show that if a structure collapse during the earthquake, the collapse always occurs in the very early stage.

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

    In the last few years, the use of chromogenic and fluorogenic reactions for the identification of the most important pathogens in human urinary tract infections has became a powerful tool in clinic diagnostic. The study was carry out in two hospitals in Havana City, comparing the performance of experimental medium with the traditional one: C.L.E.D. Medium produced by Centro Nacional de Biopreparados (BIOCEN). Additional biochemical test were applied (indole, motility, citrate, H2S glucose and lactose) for the more accurate identification of different strains. During the test 119 positive samples were evaluated with 82 identified as E. coli (68.9%). As coliforms 18 samples (15.1%) were identify without any biochemical test. The diagnostic sensitivity was 100% and diagnostic specificity of new medium was of 97.4% for all assayed samples.

    To monitor 3D deformations of structural vibration response, a stereovision-based 3D deformation measurement method is proposed in paper. The world coordinate system is established on structural surface, and 3D displacement equations of structural vibration response are acquired through coordinate transformation. The algorithms of edge detection, center fitting and matching constraint are developed for circular target. A shaking table test of a masonry building model under Taft and El Centro earthquake at different acceleration peak is performed in lab, 3D displacement time histories of the model are acquired by the integrated stereovision measurement system. In-plane displacement curves obtained by two methods show good agreement, this suggests that the proposed method is reliable for monitoring structural vibration response. Out-of-plane displacement curves indicate that the proposed method is feasible and useful for monitoring 3D deformations of vibration response.

    In the light of the doublet/triplet splitting, the possibilities for an intermediate mass scale in locally supersymmetric SO(10) are analysed. It is found that the subgroup SU(4)c × SU(2)L × SU(2)R and more generally left-right symmetric models are unlikely to survive as intermediate symmetries since they imply too large values of the weak mixing angle. An alternative model using the subgroup SU(3)c × U(1)L × U(1)R is discussed. Requirements from global SUSY preservation impose an extra constraint and predictions for the grand unification and the intermediate masses are obtained at MX ~ 6 × 1015 GeV and MI ~ 1012 GeV.

    This paper reports on the occurrence of filamentous fungi found on the surface of the bees body from the specie Melipona subnitida Ducke that inhabits rocky places on the semi-arid Northeastern Brazil. Bees with cause of natural death were collected of beehives belonging to the Centro de Multiplicação de Animais Silvestres of the Universidade Federal Rural do Semi-Arido. We found the fungi: Aspergillus sp. 6 (37.5%); Aspergillus niger 2 (12.5%); Penicilium sp. 2 (12.5%); Aspergillus terreus 1 (6.3%); Curvularia sp. 1 (6.35%); Monilia sp. 1 (6.3%); Nigrospora sp. 1 (6.3%); Cladosporium sp. 1 (6.3%); Tricoderma sp. 1 (6.3%).

    Gas del Estado's giant 1074-mile Centro-Oeste pipeline project - designed to ultimately transport over 350 million CF/day of natural gas from the Neuquen basin to the Campo Duran-Buenos Aires pipeline system - is now underway. The COGASCO consortium of Dutch and Argentine companies awarded the construction project will also operate and maintain the system for 15 years after its completion. In addition to the 30-in. pipelines, the agreement calls for a major compressor station at the gas field, three intermediate compressor stations, a gas-treatment plant, liquids-recovery facilities, and the metering, control, communications, and maintenance equipment for the system. Fabricated in Holland, the internally and externally coated pipe will be double-jointed to 80-ft lengths after shipment to Argentina; welders will use conventional manual-arc techniques to weld the pipeline in the field.

    This paper describes a friction-based energy dissipation unit (EDU) that has been designed to introduce supplemental damping into a circuit breaker. The brittle porcelain insulator posts of a 330 kV SF6 breaker were thus subjected to reduced forces from a design earthquake specified to have a peak ground acceleration of 1.05 g. Pull and release tests were performed to determine the dynamic properties, i.e., natural frequency, damping ratio, and mode shapes. Calculations of response of the circuit breaker to the 1940 El Centro N-S component shows that the EDU reduces the bending moment at the base of the porcelain column by a factor of three.
