    Klinefelter syndrome is the most common chromosomal aneuploidy in men (XXY karyotype, 1 in 600 live births) and results in testicular (infertility and androgen deficiency) and nontesticular (cognitive impairment and osteoporosis) deficits. The extent to which skeletal changes are due to testosterone deficiency or arise directly from gene overdosage cannot be determined easily in humans. To answer this, we generated XXY mice through a four-generation breeding scheme. Eight intact XXY and 9 XY littermate controls and 8 castrated XXY mice and 8 castrated XY littermate controls were euthanized at 1 year of age. Castration occurred 6 months prior to killing. A third group of 9 XXY and 11 XY littermates were castrated and simultaneously implanted with a 1-cm Silastic testosterone capsule 8 weeks prior to sacrifice. Tibias were harvested from all three groups and examined by micro-computed tomography and histomorphometry. Blood testosterone concentration was assayed by radioimmunoassay. Compared with intact XY controls, intact androgen-deficient XXY mice had lower bone volume (6.8% +/- 1.2% versus 8.8% +/- 1.7%, mean +/- SD, p = .01) and thinner trabeculae (50 +/- 4 µm versus 57 +/- 5 µm, p = .007). Trabecular separation (270 +/- 20 µm versus 270 +/- 20 µm) or osteoclast number relative to bone surface (2.4 +/- 1.0/mm2 versus 2.7 +/- 1.5/mm2) did not differ significantly. Testosterone-replaced XXY mice continued to show lower bone volume (5.5% +/- 2.4% versus 8.1% +/- 3.5%, p = .026). They also exhibited greater trabecular separation (380 +/- 69 µm versus 324 +/- 62 µm, p = .040) but equivalent blood testosterone concentrations (6.3 +/- 1.8 ng/mL versus 8.2 +/- 4.2 ng/mL, p = .28) compared with testosterone-replaced XY littermates. In contrast, castration alone drastically decreased bone volume (p < .001), trabecular thickness (p = .05), and trabecular separation (p

    The purpose of the “Microhydropower Handbook, Volume 1, Part 2” is to provide a mechanically proficient lay person with sufficient information to evaluate microhydropower site potential, lay out a site, select and install equipment, and finally, operate and maintain the completed system. The actual construction details of the site are not included; rather, pointers are given as to what help an individual should expect from a construction contractor, and general guidelines on construction details are provided. In addition, information about obtaining financing and permits is provided. To help offset cost, the person performing the work, referred to as the “developer,” is encouraged to do as much of the work as possible. However, developers with major areas of uncertainty should consider professional assistance.

    The first part of our work has focused on the relationship bet men tumor Volume and tumor control. Indeed, it is well known that the importance of irradiated volume could be a main parameter of radiation-induced complications. Numerous mathematical models have described the correlation between the irradiated volume and the risk of adverse effects. These models should predict the complication rate of each treatment planning. At the present time late effects have been the most studied. In this report we firstly propose a review of different mathematical models described for volume effect. Secondly, we will discuss whether these theoretical considerations can influence our view of radiation treatment planning optimization. (authors)

    The excess of 47,XXX and 47,XXY karyotypes found in cytogenetic screening studies of individuals with schizophrenia has given support for an increased risk of psychiatric illness among men and women with sex chromosomal aneuploidy (SCA). Mesial temporal lobe structures, including the amygdala and hippocampus, are thought to be associated with abnormalities of mood and behavior in humans and in the neurobiology of schizophrenia. This study focuses on variations in volumes of mesial temporal lobe structures in men and women with SCA. Utilizing an unselected birth cohort of subjects with SCA and high-resolution magnetic resonance imaging (MRI), we investigated the neuroanatomical consequences of a supernumerary X chromosome on the morphology of the amygdala and hippocampus. Regional and total brain volumes were measured in 10 subjects with 47,XXY, 10 subjects with 47,XXX, and 20 euploid controls. Amygdala volumes were significantly reduced in men with 47,XXY, compared to control men, while the decrease in women with 47,XXX was not as pronounced. Hippocampus volumes were preserved in both groups, compared to same-gender controls. Longitudinal studies of SCA individuals have shown an increased incidence of mild psychopathology and behavioral dysfunction in men with 47,XXY and more overt psychiatric illness in women with 47,XXX, compared to control populations. The alteration in amygdala volumes in individuals with a supernumerary X chromosome may provide a neuroanatomic basis for these findings.

    Lia Cigarini

    2013-07-01

    Full Text Available Este texto discute cuestiones de políticas, prácticas y discursos feministas. Habla de la ambigüedad en el feminismo que busca la normalidad, y, a la vez, una ruptura con ésta. Expone el hecho de que los que intentan "exportar" la democracia usan las mujeres para objetivos políticos. Por otra parte, el capitalismo, predicando el goce sin límite, en lugar de proporcionarlo a las mujeres, las ha convertido incluso más en objetos de deseo. Muraro y Cigarini explican cómo el miedo de las mujeres a sufrir la violencia de género ha permitido a la sociedad patriarcal controlar más a las mujeres. No se logrará un cambio de verdad hasta que los hombres no sean capaces de cuestionar su propia sexualidad e imaginario. Opinan que el feminismo "exportado" siempre es incompatible con las tradiciones culturales, religiosas o nacionalistas, ya que las feministas son mujeres que no aceptan ni la subordinación ni la asimilación a los hombres. Finalmente, afirman que no creen que se haya hecho una lectura demasiado positiva de la tradición femenina.

    Full Text Available Yaratullah Monturiol propone un diálogo basado en la acción, en la lucha de las mujeres musulmana que paso a paso llegará a transformar la realidad. Define el feminismo musulmán como plural y expone la necesidad del conocimiento de las fuentes textuales para su desarrollo y construcción identitaria. También expone los obstáculos que se han encontrado para avanzar, como la instrumentalización de la causa femenina por parte de los hombres, convirtiéndola en una plataforma personal y desvalorizándola como si fuera objeto de propaganda. Además, el posible temor de la disolución dl patriarcado ha provocado el rechazo el feminismo, y la división del mismo. Así, Monturiol presenta un feminismo islámico que lucha para cambiar, desde dentro, la forma de ver y de percibir de los musulmanes y del islam.

  2. Is it all the X: familial learning dysfunction and the impact of behavioral aspects of the phenotypic presentation of XXY?

    Science.gov (United States)

    2013-02-15

    The behavioral phenotype of children with XXY has not been extensively studied until recently and this research has been confounded by insufficient study populations and ascertainment biases. The aim of the study was to expand the behavioral aspect of the XXY phenotype as well as investigate the role of existing familial learning disabilities (FLD) on behavioral problems. Behavioral phenotype of XXY includes social anxiety, ADHD, social communication, and atypical peer interactions. The Child Behavior Checklist (CBCL), Social Responsiveness Scale (SRS), and Gilliam Autism Rating Scale (GARS) were completed by the parents of 54 boys with XXY who had not received hormonal replacement prior to participation. Our findings suggest fewer behavioral deficits and lower severity in the general 47,XXY population than previously published and found significant differences between the groups with a positive FLD on the behavioral assessments. Findings demonstrate that boys with FLD exhibit an increased incidence and severity of behavioral problems. Our study expands on the findings of Samango-Sprouse et al. [Samango-Sprouse et al. (2012b) J Intellect Disabil Res] and the significant influence that FLD has on not only neurodevelopment, but also behavioral deficits. Our study suggests that part of the XXY phenotypic profile may be modulated by FLD. Further study is underway to examine the interaction between the many salient factors effecting behavioral and neurodevelopmental progression in XXY and variant forms. © 2013 Wiley Periodicals, Inc.

    Increased acid precipitation is the main cause of extensive losses of salmonid fish stocks and other fish populations in southern Scandinavia, northeastern United States, and southeastern Canada. In addition, airborne transport of sulfur compounds are a threat to forest ecosystems and productivity, and to human health. Extensive surveys conducted in Sweden and Norway have documented adverse effects of the transport of pollutants through the atmosphere, and research has indicated that the major source of acid precipitation in Scandinavia is the combustion of fossil fuels in the heavily industrialized parts of Europe. Highly acid precipitation in a central area of Europe as early as the 1960s had a pH of 3-4, and the area is growing steadily larger. All governments should reduce emissions of pollutants to the air. The governments of Norway and Sweden have prohibited use of heavy oil containing over 1% sulfur. World efforts to monitor and evaluate long-range transmissions of air pollutants across national frontiers must be intensified, and data collection should be integrated in the United Nation's global environmental monitoring system. The present policy in some countries of dispersing harmful pollutants by means of tall stacks is no longer acceptable. International cooperation in reducing air pollutant emissions is needed.

    Volume is an important parameter of radiation therapy. Local control is inversely related to tumor size and the complication rate increases with the importance of the irradiated volume. Although the effect of irradiated volume has been widely reported since the beginning of radiotherapy, it has been less studied than other radiation parameters such as dose, fractionation, or treatment duration. One of the first organ system in which the adverse effect of increased volume was well defined is the skin. Over the last twenty years, numerous mathematical models have been developed for different organs. In this report we will discuss the relation between irradiated volume and tumor control. In a second article we will study the impact of irradiated volume on radiation adverse effects. (authors)

  14. Alemania siglo XXI: un balance

    Martha Lucía Quiroga Riviere

    2009-11-01

    Full Text Available Veinte años han pasado desde que se dieron los sucesos en la República Democrática Alemana (RDA que llevarían, en noviembre de 1989, a la caída del muro de Berlín y a la reunificación de Alemania el 3 de octubre de 1990. El proceso de unificación alemana dio pie en sus comienzos a una optimista visión que, sin embargo, con el paso del tiempo ha cambiado de tal forma que hoy se habla del ‘messogiorno alemán’ para designar a la zona oriental comparándola con la zona deprimida del sur de Italia. Pero la Alemania unificada en el contexto internacional supuso también cambios para la zona occidental que, entre otros, se han traducido en la crisis del sector industrial tradicional y en el desempleo estructural. Así, a la difícil constelación de la situación interna de la Alemania reunificada, se ha adicionado la realidad internacional con una decreciente producción industrial como fenómeno global en todas las viejas naciones industriales y con un proceso de desregularización que significó en Alemania oriental la ‘privatización de toda la sociedad’. En Alemania se han llevado y se están llevando cambios sociales profundos, que no tienen comparación con ningún otro país de las potencias occidentales ni, en el caso de la ex RDA con ningún país del este. Evaluar el proceso de unificación alemana, primera potencia europea y motor del proceso de integración en ese continente, se hace imperante. El presente artículo intenta hacer un diagnóstico parcial de la nueva realidad en la Alemania unificadaa comienzos del siglo XXI.

    Full Text Available Este escrito hace un análisis crítico de una de las fuentes del socialismo del siglo XXI. Los regímenes socialistas del siglo XX distorsionaron el modelo teórico marxista, en parte debido a la imposibilidad del cálculo económico en el sistema socialista centralizado. Allin Cottrell y Paul Cockshott sostienen que esta imposibilidad se puede superar con el uso de computadores y la tecnología de Internet. El artículo critica algunos aspectos económicos y políticos de su propuesta. La crítica de los aspectos económicos se inspira en el socialismo de mercado, mientras que la de los aspectos políticos se desarrolla a partir de los debates sobre el liberalismo político o igualitario.

    The Lasershot Marking System uses laser pulses to safely and permanently impress identification markings on metal components. This process does not remove material or change surface chemistry and actually increases the marked area's resistance to fatigue and corrosion failure. Lasershot marking is ideally suited for marking parts used in situations where safety is critical--from hip-joint replacements to commercial airliner components. The minimum size of the mark is limited only by the resolution of the reading system, allowing manufacturers to mark parts which, up to now, have been too small to label with mechanical peening techniques. The high resolution of the Lasershot marks makes them difficult to reproduce, providing a solution to the ongoing problem of inferior, counterfeited parts. The high marking rate of up to six marks per second makes this system practical and cost-effective for marking high-volume components.

  1. Oak Ridge National Laboratory Technology Logic Diagram. Volume 2, Technology Logic Diagram: Part B, Remedial Action

    Energy Technology Data Exchange (ETDEWEB)

    1993-09-01

    The Oak Ridge National Laboratory Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates environmental restoration (ER) and waste management (WM) problems at Oak Ridge National Laboratory (ORNL) to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration, testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to decontamination and decommissioning (D&D), remedial action (RA), and WM activities. The TLD consists of three fundamentally separate volumes: Vol. 1 (Technology Evaluation), Vol. 2 (Technology Logic Diagram), and Vol. 3 (Technology Evaluation Data Sheets). Part A of Vols. 1. and 2 focuses on D&D. Part B of Vols. 1 and 2 focuses on the RA of contaminated facilities. Part C of Vols. 1 and 2 focuses on WM. Each part of Vol. 1 contains an overview of the TLD, an explanation of the program-specific responsibilities, a review of identified technologies, and the rankings of remedial technologies. Volume 2 (Pts. A, B, and C) contains the logic linkages among EM goals, environmental problems, and the various technologies that have the potential to solve these problems. Volume 3 (Pts. A, B, and C) contains the TLD data sheets. Remedial action is the focus of Vol. 2, Pt. B, which has been divided into the three necessary subelements of the RA: characterization, RA, and robotics and automation. Each of these sections address general ORNL problems, which are then broken down by problem area/constituents and linked to potential remedial technologies. The diagrams also contain summary information about a technology`s status, its science and technology needs, and its implementation needs.

  10. [Fertility in patients with Klinefelter syndrome (47,XXY)].

    Science.gov (United States)

    Kliesch, S; Zitzmann, M; Behre, H M

    2011-01-01

    In the past 10 years, our knowledge about fertility chances of patients with Klinefelter syndrome (KS, 47,XXY) has changed considerably, especially when regarding the possibility of IVF ICSI treatment (in vitro fertilisation, intracytoplasmic sperm injection) with single testicular spermatozoa. Thus, it is important to take this knowledge into consideration when counselling Klinefelter patients.Germ cell degeneration in the testicles of Klinefelter patients due to their additional X chromosome is an important phenomenon in this disease which is not yet fully understood. When entering puberty, the testicular volume of KS patients increases for a short time with rising testosterone and inhibin B levels at the same time. These decrease, however, and FSH increases during puberty. This seems to indicate a critical point in time when spermatogenetic function of the testicles could still be existent. Thus, in early puberty there could possibly be a time slot when spermatozoa could be detected in the ejaculate or-if not-at least in the testicular tissue. These could be extracted by testicular sperm extraction, cryopreserved and used for intracytoplasmic sperm injection therapy later on. In the literature, a total of 133 births of children from Klinefelter fathers have been reported. This early specific procedure could lead to a better acceptance of their diagnosis and also offer the option of not being incurably infertile.

    Full Text Available En este trabajo se aborda la dinámica de la aplicación del modelo neoliberal en Venezuela y sus consecuencias económicas, políticas y sociales hasta llegar a la propuesta de construir el socialismo del siglo XXI. Para ello hacemos una breve retrospectiva de lo que ha sido la sociedad venezolana desde la década de 1970, del auge rentístico hasta llegar a la crisis de la década de 1980 y la inserción del programa neoliberal. La aplicación del modelo neoliberal en Venezuela, como en buen parte de América Latina, no fue un proceso fácil, por el contrario produjo fuertes conflictos y contradicciones. Asimismo, el periodo iniciado en 1999 con la llegada de Hugo Chávez al poder está cargado de dificultades y obstáculos, pero sin lugar a duda ha sido un proyecto contra el neoliberalismo. Por ello el objetivo de este trabajo es revisar el proceso venezolano hacia el socialismo.

    2011-10-01

    Nonnegative matrix factorization (NMF) with minimum-volume-constraint (MVC) is exploited in this paper. Our results show that MVC can actually improve the sparseness of the results of NMF. This sparseness is L(0)-norm oriented and can give desirable results even in very weak sparseness situations, thereby leading to the significantly enhanced ability of learning parts of NMF. The close relation between NMF, sparse NMF, and the MVC_NMF is discussed first. Then two algorithms are proposed to solve the MVC_NMF model. One is called quadratic programming_MVC_NMF (QP_MVC_NMF) which is based on quadratic programming and the other is called negative glow_MVC_NMF (NG_MVC_NMF) because it uses multiplicative updates incorporating natural gradient ingeniously. The QP_MVC_NMF algorithm is quite efficient for small-scale problems and the NG_MVC_NMF algorithm is more suitable for large-scale problems. Simulations show the efficiency and validity of the proposed methods in applications of blind source separation and human face images analysis.

El texto valora una serie de cuestiones clave: ¿responde la vivienda a la diversidad de la sociedad? ¿Contribuye a mejorar la calidad de la ciudad y el territorio? ¿Se hace un uso razonable de las tecnologías disponibles? ¿Responde a unos objetivos de sostenibilidad? Los parámetros para el diseño de la vivienda en la propuesta planteada parten de la definición de unos criterios básicos que se complementan con una serie de diagramas sobre las relaciones idóneas entre ámbitos de la vivienda y espacios del edificio. Se genera un sistema de valoración integral, formado por 14 + 1 variables imprescindibles, que permite proyectar y evaluar proyectos. En conclusión, la calidad de la vivienda se resuelve tanto en la correcta resolución de su interior, como en su contacto con el espacio público del barrio, mediante una diversidad de gradientes que pasen de lo urbano a lo privado.

    The XXI Century Academy was a 6-year state-initiated intervention program that served as an alternative to basketball clubs for players in the u-14 and u-18 age groups in Spain, under guidelines established by the Spanish Basketball Federation. It was an important and unique project on talent development in basketball. To the best of the authors' knowledge, no evidence has been reported on long-term athlete development programs in basketball worldwide. The main aim of this report is to describe the design and evaluation methods used for the XXI Century Academy as a long-term intervention program in the elite Spanish Basketball Academy, aiming to prepare basketball players to compete at the elite level. The monitoring time lasted from 1996 to 2001. A total of 55 players were assigned to the intervention groups based on age, position, maturation level, and country of origin. During this process, participants competed in up to two categories in addition to playing competitive official matches worldwide in international tournaments in their categories and with the national team in the European and World Championships (u-14 - u-18). Participants included 1 NBA player, 3 national A Team players, 10 ACB (First Spanish League) players, 5 LEB (second League) players and 39 LEB-2 EBA (third League) players. Assessments took place in a High-Performance Sports Center (CPT FADURA-GETXO- Basque Government, Getxo, Vizcaya, Spain) and consisted of health questionnaires, anthropometric measures, blood parameters, maturation level, birth age, fitness tests, training volume and intensity, physical activity, technical and tactical training, dietary intake, supplementation and injuries. Each player was assessed 4 times per year (September, December, April, June) for 4 years (16 data points). This is a purely methodological paper describing the design and evaluation methods used in the XXI Century Project, which will be used as a basis for future reporting of results. Therefore, the

  13. Oak Ridge National Laboratory Technology Logic Diagram. Volume 3, Technology evaluation data sheets: Part B, Dismantlement, Remedial action

    Energy Technology Data Exchange (ETDEWEB)

    1993-09-01

    The Oak Ridge National Laboratory Technology Logic Diagram (TLD) was developed to provide a decision support tool that relates environmental restoration (ER) and waste management (WM) problems at Oak Ridge National Laboratory (ORNL) to potential technologies that can remediate these problems. The TLD identifies the research, development, demonstration testing, and evaluation needed to develop these technologies to a state that allows technology transfer and application to decontamination and decommissioning (D&D), remedial action (RA), and WM activities. The TLD consists of three fundamentally separate volumes: Vol. 1, Technology Evaluation; Vol. 2, Technology Logic Diagram and Vol. 3, Technology EvaLuation Data Sheets. Part A of Vols. 1 and 2 focuses on RA. Part B of Vols. 1 and 2 focuses on the D&D of contaminated facilities. Part C of Vols. 1 and 2 focuses on WM. Each part of Vol. 1 contains an overview of the TM, an explanation of the problems facing the volume-specific program, a review of identified technologies, and rankings of technologies applicable to the site. Volume 2 (Pts. A. B. and C) contains the logic linkages among EM goals, environmental problems, and the various technologies that have the potential to solve these problems. Volume 3 (Pts. A. B, and C) contains the TLD data sheets. This volume provides the technology evaluation data sheets (TEDS) for ER/WM activities (D&D, RA and WM) that are referenced by a TEDS code number in Vol. 2 of the TLD. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than is given for the technologies in Vol. 2.

Lo que tendríamos que conseguir es constituir escuelas que sean demo- cráticas y que preparen a los individuos para actuar como auténticos ciudadanos, y no como súbditos. ¿Cómo se hace?, ¿cómo podemos llegar hacia una escuela que cumpla esas funciones?, ¿qué tendríamos que hacer en las escuelas para poder encaminarnos hacia la formación de individuos que tengan este tipo de características? Si optamos por fomentar la existencia de individuos felices y au- tónomos hay que comenzar por emprender una serie de reformas.

    Full Text Available El frenético y paradójico movimiento que marca la convivencia de los individuos en el siglo XXI, produce cambios en las formas de representación de la realidad, pues al cambiar nuestra percepción del mundo y la forma en que habitamos en él, cambian las maneras de representarlo. Aquí surge y se hace útil la noción de intermedialidad, porque nos permite dar cuenta de los espacios de diálogo entre las prácticas significantes -o procesos artístico-culturales- y los medios tecnológicos o digitales. Cuando se habla de intermedialidades surgen varias preguntas fundamentales: ¿qué sucede cuando dialogan diversas manifestaciones artísticas ontológicamente tradicionales con las formas de expresión propias de las tecnologías digitales? ¿Cuáles son las implicaciones del concepto de intermedialidad? y, en el contexto de la academia, ¿qué nuevos campos de estudio surgen al partir de esta noción? ¿Qué impacto tienen los estudios desde la intermedialidad sobre el proceso de enseñanza-aprendizaje y sobre la investigación que efectuamos desde las diversas disciplinas, sobre el mundo de la industria cultural y sobre el patrimonio cultural de  nuestros países? Algunas de estas preguntas procuran ser contestadas en este trabajo, otras solamente se plantean para generar un debate necesario.

No século XXI o conflito que se apresenta com maior evidência se relaciona ao uso e preservação (e ou conservação dos recursos naturais, denominado conflitos socioambientais, são fundamentais por conter nas suas análises a discussão da permanência da humanidade no planeta. A natureza faz parte dos interesses difusos, isto é, cada indivíduo gostaria que os recursos naturais fossem preservados/conservados, porém, poucos adotam estas ações como preponderantes em suas atividades socioeconômicas, aumentando a pressão sobre a natureza e a escassez de bens naturais se torna iminente. Neste contexto é imprescindível avaliar a possibilidade de inversão do processo e ponderar sobre a comunalização de alguns recursos naturais e isto significa transformar em bens comuns, recursos anteriormente privatizados, atitude que intensificará os conflitos relacionados à natureza. Objetivando avaliar as teorias relacionadas aos conflitos envolvendo os recursos naturais em países desenvolvidos e em desenvolvimento foi realizada pesquisa bibliográfica sobre as principais teorias e metodologias aplicadas na resolução de conflitos socioambientais.

    This report provides perspectives gained by reviewing 75 Individual Plant Examination (IPE) submittals pertaining to 108 nuclear power plant units. IPEs are probabilistic analyses that estimate the core damage frequency (CDF) and containment performance for accidents initiated by internal events. The US Nuclear Regulatory Commission (NRC) reviewed the IPE submittals with the objective of gaining perspectives in three major areas: (1) improvements made to individual plants as a result of their IPEs and the collective results of the IPE program, (2) plant-specific design and operational features and modeling assumptions that significantly affect the estimates of CDF and containment performance, and (3) strengths and weaknesses of the models and methods used in the IPEs. These perspectives are gained by assessing the core damage and containment performance results, including overall CDF, accident sequences, dominant contributions to component failure and human error, and containment failure modes. Methods, data, boundary conditions, and assumptions used in the IPEs are considered in understanding the differences and similarities observed among the various types of plants. This report is divided into three volumes containing six parts. Part 1 is a summary report of the key perspectives gained in each of the areas identified above, with a discussion of the NRC`s overall conclusions and observations. Part 2 discusses key perspectives regarding the impact of the IPE Program on reactor safety. Part 3 discusses perspectives gained from the IPE results regarding CDF, containment performance, and human actions. Part 4 discusses perspectives regarding the IPE models and methods. Part 5 discusses additional IPE perspectives. Part 6 contains Appendices A, B and C which provide the references of the information from the IPEs, updated PRA results, and public comments on draft NUREG-1560 respectively.

    decreciente se estabilizaba y a partir de 1984, comenzaba a ascender paulatinamente y, en algunas regiones del planeta en forma vertiginosa.

    Este despertar del proceso llamó naturalmente la atención de los científicos, algunos de cuyos exponentes más destacados se reunieron en Londres en abril de 1993 en la Escuela Londinense de Higiene y Medicina Tropical, para celebrar el tercer Foro sobre tuberculosis que se llamó De regreso al futuro (Back to the future con el objeto de analizar las causas productoras de este inesperado ascenso.

    Este renacer de la tuberculosis en el mundo se destacaba desde hacía algún tiempo no solamente en las revistas médicas sino que en los periódicos diarios y en los magazines semanales tanto de Europa como de los EE.UU., se observaban con gran frecuencia llamativos titulares referentes al asunto.

    El factor hallado como el más relievante en la patología actual que pudiera destacarse como el causante de esta reactivación, fue el Síndrome de Inumodeficiencia Adquirida SIDA nuevo proceso descrito clínicamente en 1981 y cuya causaetiológica es descubierta por Montagnier en Francia y Gallo en EE.UU. en 1983 -101 años después del descubrimiento de Koch-, un virus de características especiales entre ellas las mutaciones frecuentes, proceso que se propagó rápidamente primero entre los negros especialmente de Haití, luego entre los homosexuales y posteriormente cubriendo todos los estratos humanos, tanto en sexo, como en estado socioeconómico y razas, para convertirse en la epidemia más peligrosa y de más difícil control que ataca en la actualidad al hombre.

    Al coincidir la iniciación de la epidemia de SIDA con el alza en la incidencia de TBC, los estudios del Foro menciona do fueron dedicados especialmente a la simbiosis de estos dos procesos patológicos, que constituyen sin duda la llamada EPIDEMIA DEL SIGLO XXI.

    2012-09-01

    Full Text Available Abstract Background Diffuse myocardial fibrosis, and to a lesser extent global myocardial edema, are important processes in heart disease which are difficult to assess or quantify with cardiovascular magnetic resonance (CMR using conventional late gadolinium enhancement (LGE or T1-mapping. Measurement of the myocardial extracellular volume fraction (ECV circumvents factors that confound T1-weighted images or T1-maps. We hypothesized that quantitative assessment of myocardial ECV would be clinically useful for detecting both focal and diffuse myocardial abnormalities in a variety of common and uncommon heart diseases. Methods A total of 156 subjects were imaged including 62 with normal findings, 33 patients with chronic myocardial infarction (MI, 33 with hypertrophic cardiomyopathy (HCM, 15 with non-ischemic dilated cardiomyopathy (DCM, 7 with acute myocarditis, 4 with cardiac amyloidosis, and 2 with systemic capillary leak syndrome (SCLS. Motion corrected ECV maps were generated automatically from T1-maps acquired pre- and post-contrast calibrated by blood hematocrit. Abnormally-elevated ECV was defined as >2SD from the mean ECV in individuals with normal findings. In HCM the size of regions of LGE was quantified as the region >2 SD from remote. Results Mean ECV of 62 normal individuals was 25.4 ± 2.5% (m ± SD, normal range 20.4%-30.4%. Mean ECV within the core of chronic myocardial infarctions (without MVO (N = 33 measured 68.5 ± 8.6% (p  Conclusions ECV mapping appears promising to complement LGE imaging in cases of more homogenously diffuse disease. The ability to display ECV maps in units that are physiologically intuitive and may be interpreted on an absolute scale offers the potential for detection of diffuse disease and measurement of the extent and severity of abnormal regions.

    The attachments contained within this appendix provide additional details about the model development and estimation process which do not easily lend themselves to incorporation in the main body of the model documentation report. The information provided in these attachments is not integral to the understanding of the model`s operation, but provides the reader with opportunity to gain a deeper understanding of some of the model`s underlying assumptions. There will be a slight degree of replication of materials found elsewhere in the documentation, made unavoidable by the dictates of internal consistency. Each attachment is associated with a specific component of the transportation model; the presentation follows the same sequence of modules employed in Volume 1. The following attachments are contained in Appendix F: Fuel Economy Model (FEM)--provides a discussion of the FEM vehicle demand and performance by size class models; Alternative Fuel Vehicle (AFV) Model--describes data input sources and extrapolation methodologies; Light-Duty Vehicle (LDV) Stock Model--discusses the fuel economy gap estimation methodology; Light Duty Vehicle Fleet Model--presents the data development for business, utility, and government fleet vehicles; Light Commercial Truck Model--describes the stratification methodology and data sources employed in estimating the stock and performance of LCT`s; Air Travel Demand Model--presents the derivation of the demographic index, used to modify estimates of personal travel demand; and Airborne Emissions Model--describes the derivation of emissions factors used to associate transportation measures to levels of airborne emissions of several pollutants.

    This is the tenth Annual Site Environmental Report (ASER), documenting the progress of environmental programs at the U.S. Department of Energy (DOE) Waste Isolation Pilot Plant (WIPP). The most significant change affecting the WIPP facility in 1993 was the cancellation of the Test Phase. All activities pertaining to the Test Phase will now be conducted at the Idaho National Engineering laboratory. Even though the cancellation of the Test Phase was a significant change in work scope for the WIPP, there are still numerous environmental monitoring and reporting activities that must be performed as a routine part of daily operations. These activities, and the WIPP's ability to demonstrate compliance with both state and federal environmental compliance requirements, are documented in this report. This report is a compilation and summarization of environmental data collected at the WIPP site.

    Energy Technology Data Exchange (ETDEWEB)

    1981-09-01

    Statistical data on energy production and consumption and supporting information were obtained from US Bureau of Mines records supplemented by additional data obtained in Portugal. Geologic descriptions and analysis of known areas and of areas having possible future potential have been prepared by the US Geological Survey. Portugal lacks sufficient indigenous supplies of organic fuels to meet its energy demands, and so must import large quantities of petroleum and coal. Approximately 80% of Portugal's electric energy is produced by hydroelectric stations; thermal stations produce the other 20%. Portugal has produced no crude oil, natural gas, or condensate; no resources or reserves in these categories are listed for Portugal in the 1976 World Energy Conference report. Until the last year or so (1980), no significant onshore petroleum exploration had been done in Portugal since 1963. Production of coal in Portugal has declined steadily to the present annual yield of about 200,000 metric tons. On the basis of estimates in only three coal fields, resources of coal of all ranks in Portugal total at least 76 million (10/sup 6/) metric tons. Uranium is mined near Viseu and Guarda in the northern part of Portugal; the Nisa mine in east-central Portugal will begin producing uranium ore in 1985 after installation of a processing plant. Portugal produced 95 metric tons of uranium oxide (U/sub 3/O/sub 8/) from ore stocks in each year from 1972 through 1974; production is assumed to have continued at the same rate since then. Geothermal energy has not been developed in mainland Portugal; however, hot springs that may have geothermal energy potential are known in the Minho district in the northwest. Geothermal energy resources exist in the Azores and a program of evaluation and exploration with technical assistance from the USGS is presently in progress there.

    The second part of the sixth RHIC Spin Collaboration (RSC) meeting was held on November 15, 2001 at Brookhaven National Laboratory. Previous meetings have elaborated on the new generation of proton spin-structure studies (e.g. gluon polarization and flavor separation of q and {bar q} polarizations via real W{sup {+-}} production) enabled by studying polarized proton collisions at energies and momentum transfers where perturbative QCD models are expected to be applicable. The focus of this meeting was on many of the experimental issues that must be resolved to achieve these physics goals. This summary is written with the benefit of hindsight following the completion of the first-ever run of a polarized proton collider. This first run can be considered as a successfully completed milestone of the RHIC Spin Collaboration. Other milestones remain important. Long term machine items were identified in Waldo Mackay's talk, the most important being the completion of the spin rotator magnets that will be installed in 2002 to allow the flexible orientation of the proton beam polarization at the PHENM and STAR experiments. At the meeting Waldo discussed a stronger partial snake magnet for the AGS as a means of producing highly polarized proton beams to inject into RHIC. Developments subsequent to this meeting suggest that a superconducting helical dipole magnet may be feasible for the AGS, and is likely to be needed to achieve the 70% beam polarization in RHIC. Longer term items were also presented, including potential increases in luminosity by the addition of electron cooling to RHIC and the possibility of increasing the collision energy by {approx}20% by replacement of the DX magnets. These items could be considered for a second generation of RHIC spin experiments. The other topics covered at the meeting were related to polarimetry and to the absolute calibration of the proton beam polarization in RHIC. These topics were divided into short- and long-term solutions to

    The continuous sulfur dioxide detector (CSD) is a sensitive instrument for reliable measurements at high time resolution in the atmosphere. This new instrument is based on a SO2 measurement technique utilizing the sulfur chemiluminescence detector, previously validated in a rigorously blind experiment sponsored by the National Science Foundation. Simplified sample handling, dénuder separation technology, and the intrinsic sensitivity and fast response of the detector permit measurement at levels below 100 parts per trillion by volume in tens of seconds with the CSD. The CSD provides a differential measurement where response from ambient SO2 is determined by the difference between air containing SO2 and air scrubbed of SO2, where both air samples contain other detectable sulfur species. Digital signal post processing with phase-locked amplification of the detector signal enhances the precision and temporal resolution of the CSD. Oversampling of the detector signal at 10 Hz permits subsequent data retrieval to be adapted to changing ambient levels by either enhancing signal to noise when sulfur dioxide levels are low or by maximizing temporal resolution of derived data when levels are high. he instrument has advantages over existing instruments based on Chromatographie separation in that the CSD provides accurate and reliable measurements at low parts per trillion by volume sulfur dioxide with high time resolution. The CSD is compact and automated and does not require cryogenic materials, making this instrument suitable for remote field locations. The high temporal resolution, specificity for SO2, and sensitivity of the CSD make it a good candidate for installation on an aircraft. Airborne studies of SO2 with a sensitive, fast time response instrument may offer new insight into the understanding of phenomena such as gas-to-particle conversion, long-range transport of pollutants, and the oxidation of biogenically produced sulfur gases.

    Conferencia dictada en el Hospital Infantil Lorencita Villegas de Santos por la doctora Inés Durana Samper.

    Considero un honor y un privilegio compartir con ustedes algunos de los retos de Enfermería Profesional en el campo pediátrico y de salud familiar comunitaria, para su liderazgo en el Hospital Infantil.

    He dividido mi presentación en dos partes. En la primera hago una breve reflexión sobre la evolución y afloramiento de nuestros conocimientos inherentes al ejercicio de la enfermería clínica. En la segunda parte, me proyecto al futuro mostrando un nuevo perfil que confió encuentre eco en las generaciones jóvenes a quienes les corresponde hacer la transición en el siglo XXI.

    Evolución, Oportunidades y Retos

    En la actualidad y en especial al interior de enfermería hospitalaria se atravieza por una gran crisis, en valores, en asuntos económicos, en condiciones de trabajo y otros que merecen nuestra atención colegiada para su solución.

    Para explicarla me atrevo a remontarme y analizar un proceso histórico documentado durante mis estudios para obtener el doctorado. Según Fridson, (1, 1970 sociológo dedicado al análisis de las profesiones, Enfermería y Medicina escogieron rutas diferentes para su desarrollo ocupacional. Medicina en la década del 30 y bajo los efectos de la gran depresión económica, desarrolló sus especialidades clínicas en base a la práctica surgida con el comienzo del internado rotando por los servicios tradicionales de medicina, cirugía, pediatría y obstetricia.

    Esto contribuyó a que en el seno de los hospitales surgieran otras carreras como apoyo a esas especialidades, campo ocupado casi con exclusividad hasta entonces por· Enfermería; del fisiatra y neumólogo, se formaron las terapias; del patólogo las bacteriólogas. También la introducción de alta tecnología desarrolló una gama de

De hecho, el tema es realmente de actualidad puesto que en América Latina vivimos por primera vez esta situación, después de mucho tiempo, en el que pasamos de las resistencias a las alternativas, no digo que sea la alternativa definitiva, pero se trata de pasos en dirección de las alternativas. América Latina es el único continente en el mundo actual que experimenta alternativas. Si consideramos por ejemplo el Asia, allí se vive el neoliberalismo más como una oportunidad que como una agresión. Es muy claro para la opinión general en América Latina que el neoliberalismo ha sido una agresión económica, política, cultural. En cambio, en países como la India,Vietnam y China se mira el neoliberalismo o el capitalismo tal vez como una oportunidad, por eso estamos todavía en estado, no solamente de construcción de alternativas, sino aún de resistencias.

    Full Text Available Human trafficking and slavery of human labor are not a recent phenomenon in the context of world history. The Trafficking of human lives is part of a logic of domination and bargaining, in which the life of an individual is exchanged for its freedom, or reducing a person to the condition of a thing that can be appropriated by others. Not limited only to trafficking, the “thingfication” of the other, which also occurs in the analogue slave labor which produces illness, causing funeral songs and it becomes the faces of these wretched, gloomy figures against villainy in the world. As speech development method was used Navio Negreiro of Castro Alves, as a basis for criticizing the perpetuation of man’s enslavement practice. It is observed that at the time the poet has denounced the hideous and vile practice, and we find ourselves today in the XXI century, living with the banalization of life. In the same way in that century the poet urged the intellectuals and the population to embrace the abolition of slavery, we find ourselves today in such situation that require a new abolitionist consciousness. Disposing the discussion at the national level, on the history and construction of the Brazilian legal system, it is worth to observe the necessity to create a new abolitionist movement. And in this sense, we ask as the poet did: “Why do you run away like that (...? Why to run away (...?”.

    Full Text Available The phenomenon of the special relationship in BritishAmerican politics of the second part of the XX century also received intensive development in the early XXI century. In fact, according to conditions of modern processes of globalization, cooperation between the United States and Great Britain, as within framework of NATO and in other international organizations, became increasingly close. Both States played a significant role in the international policy, working on various issues of economy, politics, environment, culture, etc. Attention is drawn to the forms of cooperation between the studied States in the implementation of military initiatives in the Balkans (1998 and Iraq (2003. These events allowed characterizing the first and final stages of the development of relations between the United States and Britain in the form of «special» in the period of late XX – early XXI centuries. In the beginning of XXI century the cooperation between the U.S. and the UK in reforming NATO, taking into account national foreign policy strategy of the USA, was an example of favorable development of bilateral “special relationship”.

    2012-12-01

    Full Text Available The XXI century society is undergoing processes of economic, political, social, scientific and technological changes. There are new ways of thinking, producing and interacting. Today we talk of a "techno-scientific culture", the language of science is accepted, its production processes and its methods. It is within these guidelines, that it is essential the formation of scientifically and technologically literate citizens (Fourez, 1997, so they can reach a basic scientific culture capable of facilitating their insertion into the society of knowledge. This is the underlying reason for which, in recent times and from different perspectives, sensitive scientists and committed humanists are giving much importance to the investigation of what could be a third culture. Without scientific literacy there is no reasonable possibility of intervention in the current public debate on most issues that really matter to the community of which we are part. This is because, as it is often mentioned, science is already a substantial part of our lives. An important number of public, ethical-political or ethical-legal discussions, now relevant, assume and require some knowledge of the state of the art of one or more natural sciences.

  17. LIFE Materials: Phase Formation and Transformations in Transmutation Fuel Materials for the LIFE Engine Part I - Path Forward Volume 3

    Energy Technology Data Exchange (ETDEWEB)

    Turchi, P A; Kaufman, L; Fluss, M

    2008-12-19

    The current specifications of the LLNL fusion-fission hybrid proposal, namely LIFE, impose severe constraints on materials, and in particular on the nuclear fissile or fertile nuclear fuel and its immediate environment. This constitutes the focus of the present report with special emphasis on phase formation and phase transformations of the transmutation fuel and their consequences on particle and pebble thermal, chemical, and mechanical integrities. We first review the work that has been done in recent years to improve materials properties under the Gen-IV project, and with in particular applications to HTGR and MSR, and also under GNEP and AFCI in the USA. Our goal is to assess the nuclear fuel options that currently exist together with their issues. Among the options, it is worth mentioning TRISO, IMF, and molten salts. The later option will not be discussed in details since an entire report (Volume 8 - Molten-salt Fuels) is dedicated to it. Then, in a second part, with the specific LIFE specifications in mind, the various fuel options with their most critical issues are revisited with a path forward for each of them in terms of research, both experimental and theoretical. Since LIFE is applicable to very high burn-up of various fuels, distinctions will be made depending on the mission, i.e., energy production or incineration. Finally a few conclusions are drawn in terms of the specific needs for integrated materials modeling and the in depth knowledge on time-evolution thermo-chemistry that controls and drastically affects the performance of the nuclear materials and their immediate environment. Although LIFE demands materials that very likely have not yet been fully optimized, the challenges are not insurmountable, and a well concerted experimental-modeling effort should lead to dramatic advances that should well serve other fission programs such as Gen-IV, GNEP, AFCI as well as the international fusion program, ITER.

    Resumen. El Quijote ha cabalgado con nosotros por largo tiempo y como si no fuera suficiente la lucha contra los molinos de viento, don Quijote de la Mancha tendrá que luchar contra muchas situaciones de nuestra época actual. ¿Logrará esta hazaña el Caballero de la Triste Figura? El reto es dar la respuesta.

    Por tal motivo, la autora de este ensayo traslada al Caballero de la Triste Figura y lo inserta a la sociedad del siglo XXI. Transforma los valores, costumbres y puntos de vistas de la época en que se desarrolla la obra literaria y establece una serie de correlaciones entre el texto literario, el personaje principal y las diversas situaciones cotidianas actuales. Ciertamente, Don Quijote seguirá luchando contra las situaciones de nuestra época actual. Sin duda alguna este hidalgo está aún entre nosotros.

     

    Abstract. Don Quixote has ridden with us for a long time now, and as if his fight against windmills were not enough, Don Quixote still has many more difficult situations to combat in the present times.  Will the Knight of the Sad Figure accomplish this new deed?

    It is our challenge to find an answer to this inquiry. For this purpose, the author of this essay inserts the Knight of the Sad Figure in XXI century society. The author transforms the values, costumes and points of view of the times of the literary piece and establishes a series of relationships between the literary text, the main character and several current daily life situations. Don Quixote will certainly continue his fight against all the conditions we encounter nowadays. There is no doubt, then, that this knight still lives among us.

    2001-06-01

    The child with XXY or a variant form is a fertile ground for scientific investigation because of the homogeneity of the disorder and the increased prevalence of learning disorders associated with it. However, the research studies of boys with XXY (Klinefelter syndrome) have been plagued by a variety of factors from small sample size, methodological flaws, and ascertainment bias. In spite of these shortcomings, there remains some consistency to the neurobehavioral profile of this disorder. In general, the prenatal population of boys with XXY is less affected developmentally and is more academically successful than the boys identified through postnatal diagnosis. Boys with XXY often have decreased muscle tonus, delayed speech, and language skills with an increased incidence of reading differences and dyslexia. It does appear that social difficulties may be mediated by language processing problems and temperamental issues. The neurobehavioral and neurocognitive phenotype of boys with XXY places them at risk for school failure and secondary behavioral disturbances. Therefore, early evaluation and intervention is strongly recommended since the prognosis may be improved significantly with appropriate therapeutic intervention. The natural history of this disorder is not well defined from the neurodevelopmental, neuroimaging, and cytogenetic perspective. Further investigation into the effects and the relationships between parental origin and outcome may provide many answers regarding the variability of the disorder. Lastly, some promising theories have been postulated regarding the neurobiological etiology of this disorder, which requires more investigation if we are to understand the pathogenesis of this XXY and its effect on learning.

    Full Text Available En los últimos veinte años el extraordinario auge de la informática ha permitido desarrollos tecnológicos trascendentales al servicio de la precisión en los tratamientos radioterápicos: en la obtención de imágenes en tres dimensiones, en los sistemas de planificación y en las unidades de irradiación. De manera que en menos de dos décadas se ha pasado de la radioterapia en dos dimensiones (RT 2D a la radioterapia conformada en 3D (RTC3D y a la modulación de la intensidad de la radiación para la máxima conformación (IMRT. La alta precisión en la entrega de la radiación ajusta la dosis prescrita al volumen blanco preservando mejor los tejidos sanos adyacentes. De manera que se puede aspirar a mejorar el índice terapéutico en dos sentidos, bien disminuyendo la toxicidad tardía cuando esta es un problema de suficiente entidad o escalando la dosis en el volumen blanco para aumentar el control tumoral sin provocar más la toxicidad. Un último componente en llegar a la radioterapia del presente resulta de importancia capital: la imagen guiada, que permite dirigir los haces de irradiación adaptándolos a los posibles cambios de posición del volumen blanco antes o durante el tratamiento.In the last twenty years the extraordinary rise of information technology has made possible key technological developments at the service of precision in radiotherapy treatments: in obtaining three-dimensional images, in systems planning and in radiation units. Thus in less than two decades there progress has been made from radiotherapy in two dimensions (RT 2D to 3D conformal radiotherapy (3DCRT and to modulation of intensity modulated radiotherapy for maximum conformation (IMRT. High precision in radiation delivery adjusts the prescribed dosage to the white volume, better preserving the adjacent healthy tissue. It is thus possible to aspire to improving the therapeutic index in two respects, either reducing late toxicity when this is a problem of

    Neuroimaging studies have shown that having an extra X chromosome is associated with abnormal structure and function of brain areas in the frontal lobe, which is crucially involved in executive functioning. However, there is little of knowledge of the type and severity of executive dysfunction, and the impact on emotional and behavioral problems. The present study aims to provide in this. In total, 40 children (23 boys with 47,XXY and 17 girls with 47,XXX) with an extra X chromosome and 100 non-clinical controls (47 boys and 53 girls) participated in the study. The participants were 9-18 years old. Processing speed and executive functioning were assessed using the Amsterdam Neuropsychological Testbattery (ANT) and the Dysexecutive Questionnaire (DEX). Problems in emotional and behavioral functioning were assessed with the Childhood Behavior Checklist (CBCL). Children with an extra X chromosome showed deficits in inhibition, mental flexibility, sustained attention and visual working memory. Parental report showed high levels of everyday manifestations of executive dysfunction. More severe inhibition difficulties were associated with higher levels of thought problems, aggression and rule breaking behavior. Boys and girls with an extra X chromosome could not be differentiated based on severity of executive dysfunction, however, girls had lower information processing speed than boys. These findings suggest that executive dysfunction may be part of the phenotype of children with an extra X chromosome, impacting the ability to function adequately in everyday life. Furthermore, children with impairments in inhibition may have more problems in regulating their thinking, emotions and behavior.

    The aim of the study was to examine the impact of familial learning disabilities (FLD) on the phenotypic profile of 47, XXY males and the possibility that 47, XXY males with more severe cognitive deficits may be partially a consequence of familial dyslexia/reading disorder. We wondered if FLD could pose an additional risk for complex neurodevelopmental differences in 47, XXY. The neurodevelopmental profile of males with 47, XXY has been characterized by developmental dyspraxia, language-based learning disorders, executive dysfunction, reading, and attentional deficits. One hundred eighteen boys with 47, XXY diagnosed prenatally who did not receive early hormonal treatment were divided into two groups based on positive histories of FLD and given comprehensive neurodevelopmental evaluations between 36 and 108 months. The assessments included intelligence (nonverbal and verbal), neuromotor (fine and gross), speech, and language. The group with FLD performed significantly lower in multiple neurodevelopmental domains of the Wechsler of VIQ P = 0.015, FSIQ P = 0.0005, the Brief IQ P = 0.0525 of the Leiter, in Auditory Comprehension P = 0.0505, Expressive Communication P = 0.0055, and neuromotor domains of Manual Coordination P = 0.0032, Fine Motor Control P = 0.0378, and Motor Coordination P = 0.008. Our study demonstrates the influence of FLD on neurodevelopment and expands the phenotypic profile of 47, XXY, suggesting some neurodevelopmental variability is attributable to other factors than the additional X. FLD may increase the vulnerability of the 47, XXY children and anticipatory guidance should be provided to families.

    Klinefelter syndrome (47, XXY) is associated with several physical, cognitive, and behavioral consequences. In terms of social development, there is an increased risk of autism symptomatology. However, it remains unclear how social deficits are related to abnormal brain development and to what degree underlying mechanisms of social dysfunction in 47, XXY are similar to, or different from, those in idiopathic autism (ASD). This study was aimed at investigating the neural architecture of brain structures related to social information processing in boys with 47, XXY, also in comparison with boys with idiopathic ASD. MRI scans of 16 boys with 47, XXY, 16 with ASD, and 16 nonclinical, male controls were analyzed using voxel-based morphometry (VBM). A region of interest mask containing the superior temporal cortex, amygdala, orbitofrontal cortex (OFC), insular cortex, and medial frontal cortex was used. The Social Responsiveness Scale (SRS) was used to assess degree of autism spectrum symptoms. The 47, XXY group could not be distinguished from the ASD group on mean SRS scores, and their scores were significantly higher than in controls. VBM showed that boys with 47, XXY have significant gray matter volume reductions in the left and right insula, and the left OFC, compared with controls and boys with ASD. Additionally, boys with 47, XXY had significantly less gray matter in the right superior temporal gyrus than controls. These results imply social challenges associated with 47, XXY may be rooted in neural anatomy, and autism symptoms in boys with 47, XXY and boys with ASD might have, at least partially, different underlying etiologies.

    Volume II of the Solar/Hydrogen Systems Assessment contract report (2 volumes) is basically a technological source book. Relying heavily on expert contributions, it comprehensively reviews constituent technologies from which can be assembled a wide range of specific solar/hydrogen systems. Covered here are both direct and indirect solar energy conversion technologies; respectively, those that utilize solar radiant energy input directly and immediately, and those that absorb energy from a physical intermediary, previously energized by the sun. Solar-operated hydrogen energy production technologies are also covered in the report. The single most prominent of these is water electrolysis. Utilization of solar-produced hydrogen is outside the scope of the volume. However, the important hydrogen delivery step is treated under the delivery sub-steps of hydrogen transmission, distribution and storage. An exemplary use of the presented information is in the synthesis and analysis of those solar/hydrogen system candidates documented in the report's Volume I. Morever, it is intended that broad use be made of this technology information in the implementation of future solar/hydrogen systems. Such systems, configured on either a distributed or a central-plant basis, or both, may well be of major significance in effecting an ultimate transition to renewable energy systems.

    This work once again brings to attention the fundamental ideas of the long-term nuclear power development on the basis of the new generation of Fast neutron Reactors, naturally safe, economically attractive and employing the proliferation-resistant and low-waste fuel cycle. The Universal System Model (USM-1), new analytical research tool recently developed in N.A. Dollezhal Research and Design Institute of Power Engineering (Moscow, Russia) has been used to evaluate several scenarios (including traditional ones) of the World nuclear power development for electricity production within the XXI century. For scenarios comparison 3 criteria were used: the levelized cost of electricity, the fuel supply security (in terms of natural uranium total consumption and prospects for further fuel balance), and the potential hazard of radioactive wastes. The clear advantage of scenario with the most complete realization of the new Fast Reactors technology potential is revealed. The authors strongly believe that the prospects of this new technology worldwide implementation deserve the due attention of responsible governments and international organizations. 2 Tables, 13 Figures, 10 References.

    Under contract to the US Nuclear Regulatory Commission, Office of Nuclear Regulatory Research, the firms of S. Cohen & Associates, Inc. (SC&A) and Eastern Research Group (ERG) have compiled a report that describes the physical, chemical, and radiological properties of Class-A low-level radioactive waste. The report also presents information characterizing various methods and facilities used to treat and dispose non-radioactive waste. A database management program was developed for use in accessing, sorting, analyzing, and displaying the electronic data provided by EG&G. The program was used to present and aggregate data characterizing the radiological, physical, and chemical properties of the waste from descriptions contained in shipping manifests. The data thus retrieved are summarized in tables, histograms, and cumulative distribution curves presenting radionuclide concentration distributions in Class-A waste as a function of waste streams, by category of waste generators, and regions of the United States. The report also provides information characterizing methods and facilities used to treat and dispose non-radioactive waste, including industrial, municipal, and hazardous waste regulated under Subparts C and D of the Resource Conservation and Recovery Act (RCRA). The information includes a list of disposal options, the geographical locations of the processing and disposal facilities, and a description of the characteristics of such processing and disposal facilities. Volume 1 contains the Executive Summary, Volume 2 presents the Class-A waste database, Volume 3 presents the information characterizing non-radioactive waste management practices and facilities, and Volumes 4 to 7 contain Appendices A to P with supporting information.

    The behavioral phenotype of 47,XXY (Klinefelter syndrome) includes increased risks for developmental delays, language-based learning disabilities, executive dysfunction/ADHD, and socialemotional difficulties. However there is significant variability between individuals with 47,XXY, and many children and adolescents have minimal or no behavioral features while others have quite significant involvement. This paper describes behavioral features in a cohort of 57 children and adolescents with 47,XXY, including results on standardized measures of behavior (BASC-2), attention (Conner's Rating Scales), and social skills (Social Responsiveness Scale). A subset was directly assessed for autism spectrum disorders using the ADOS and ADIR. We discuss our results within the context of previous literature, including implications for genetic counseling, recommendations for care, and areas for future research.

    47, XXY occurs in up to 1 in 650 male births and is associated with androgen deficiency, neurodevelopmental delays, and atypical social-behaviors. Previously, we showed that young boys with 47, XXY who received early hormonal therapy (EHT) had significantly improved neurodevelopment. The objective of this follow-up study was to examine the effects of EHT on social behavior in boys with 47, XXY. The study consisted of boys prenatally diagnosed with 47, XXY who were referred for evaluations. Twenty-nine boys received three injections of 25 mg testosterone enanthate and 57 controls did not receive EHT. Behavioral functioning was assessed using the Behavior Rating Inventory of Executive Function, Social Responsiveness Scale, 2nd Ed., and the Child Behavior Checklist for Ages 6-18. The hypothesis that EHT may affect behavior was formulated prior to data collection. Questionnaire data was prospectively obtained and analyzed to test for significance between two groups. Significant differences were identified between group's scores over time in Social Communication (P=0.007), Social Cognition (P=0.006), and Total T-score (P=0.001) on the SRS-2; Initiation (P=0.05) on the BRIEF; and Externalizing Problems (P=0.024), Affective Problems (P=0.05), and Aggressive Behaviors (P=0.031) on the CBCL. This is the third study revealing positive effects of EHT on boys with XXY. There was a significant improvements associated with the 47, XXY genotype in boys who received EHT.

    Full Text Available What can the intersex body tell us? How does this issue get more complex if we think about its representation in the media, specially in cinema? In this article, starting from Lucia Puenzo's XXY, we pose these and other questions related to deviant bodies and desires. With a subversive and non-pathologizing discourse, XXY proposes a careful look at the subjectivities of these experiences. We argue that the film, in resonance with the queer studies, is alert to the politicization of the abject bodies.

    1972-01-01

    Major study areas treated in this volume are: 1) operations and control and 2) the telecommunication service system. The TDRS orbit selection, orbital deployment, ground station visibility, sequence of events from launch to final orbit position, and TDRS control center functions required for stationkeeping, repositioning, attitude control, and antenna pointing are briefly treated as part of the operations and control section. The last topic of this section concerns the operations required for efficiently providing the TDRSS user telecommunication services. The discussion treats functions of the GSFC control and data processing facility, ground station, and TDRS control center. The second major portion of this volume deals with the Telecommunication Service System (TSS) which consists of the ground station, TDRS communication equipment and the user transceiver. A summary of the requirements and objectives for the telecommunication services and a brief summary of the TSS capabilities is followed by communication system analysis, signal design, and equipment design. Finally, descriptions of the three TSS elements are presented.

    Como representante de 106 años ininterrumpidos de servicio a la medicina, de dedicación incondicional a los pacientes, quiero ser portador de un mensaje de unidad y de fraternidad para el cuerpo médico de Colombia y de la América Latina, condiciones que en la Academia Nacional de Medicina de Colombia consideramos imperativas para adecuar nuestras instituciones a los caleidoscópicos cambios del ejercicio de nuestra profesión, en los albores del siglo XXI, del tercer milenio.

    Quiero transmitirles las experiencias y las conclusiones emanadas, tanto de los diferentes foros que hemos tenido en Santa Fe de Bogotá como del 1 Encuentro Nacional de Academias de Medicina de Colombia, realizado en esta ciudad en marzo pasado. Cuando se inauguró dicho Encuentro nuestro Presidente, el Académico Gilberto Rueda Pérez, anotaba “La ciencia y la tecnología modernas reclaman para el futuro, más que nunca, la presencia directiva de la Academia, pero no de una Academia quieta, que descansa complacida en pretéritas épocas de oro, improductiva, órgano asesor a quien nadie consulta, sino de una Academia viva, dinámica, agresiva, capaz de aportar a través de su gran acerbo de inteligencia, de conocimientos y de experiencia y de su enorme poder de liderazgo, todo aquello que el cuerpo médico nacional espera de ella para el siglo XXI “.

    Años atrás, cuando se perfilaba el nombramiento de un nuevo Ministro de Salud, la Academia dirigió una carta al Presidente de la República que fue desatendida totalmente. En dicha carta la Academia le solicitaba que escogiera a un médico para que se encargara de la cartera de salud, por años en manos de administradores y economistas, con detrimento de los programas nacionales de salud y de las campañas contra los principales flagelos nosológicos de nuestra patria.

    In order to examine the feasibility of an intercity freight pipeline, it was necessary to develop cost equations for various competing transportation modes. This volume presents cost-estimating equations for rail carload, trailer-on-flatcar, truck, and freight pipeline. Section A presents mathematical equations that approximate the fully allocated and variable costs contained in the ICC cost tables for rail carload, trailer-on-flatcar (TOFC) and truck common-carrier intercity freight movements. These equations were developed to enable the user to approximate the ICC costs quickly and easily. They should find use in initial studies of costs where exact values are not needed, such as in consideration of rate changes, studies of profitability, and in general inter-modal comparisons. Section B discusses the development of a set of engineering cost equations for pneumo-capsule pipelines. The development was based on an analysis of system components and can readily be extended to other types of pipeline. The model was developed for the purpose of a feasibility study. It employs a limited number of generalized parameters and its use is recommended when sufficient detailed and specific engineering information is lacking. These models were used in the comparison of modes presented in Volume I and hence no conclusions regarding relative costs or service of the modes are presented here. The primary conclusion is that the estimates of costs resulting from these models is subject to considerable uncertainty.

    Magnetic helicity is a conserved quantity of ideal magneto-hydrodynamics characterized by an inverse turbulent cascade. Accordingly, it is often invoked as one of the basic physical quantities driving the generation and structuring of magnetic fields in a variety of astrophysical and laboratory plasmas. We provide here the first systematic comparison of six existing methods for the estimation of the helicity of magnetic fields known in a finite volume. All such methods are reviewed, benchmarked, and compared with each other, and specifically tested for accuracy and sensitivity to errors. To that purpose, we consider four groups of numerical tests, ranging from solutions of the three-dimensional, force-free equilibrium, to magneto-hydrodynamical numerical simulations. Almost all methods are found to produce the same value of magnetic helicity within few percent in all tests. In the more solar-relevant and realistic of the tests employed here, the simulation of an eruptive flux rope, the spread in the computed values obtained by all but one method is only 3 %, indicating the reliability and mutual consistency of such methods in appropriate parameter ranges. However, methods show differences in the sensitivity to numerical resolution and to errors in the solenoidal property of the input fields. In addition to finite volume methods, we also briefly discuss a method that estimates helicity from the field lines' twist, and one that exploits the field's value at one boundary and a coronal minimal connectivity instead of a pre-defined three-dimensional magnetic-field solution.

    47,XXY (Klinefelter syndrome) is the most frequent sex chromosomal disorder and affects approximately one in 660 newborn boys. The syndrome is characterized by varying degrees of cognitive, social, behavioral, and learning difficulties and in adulthood additionally primary testicular failure with small testes, hypergonadotropic hypogonadism, tall stature, and eunuchoid body proportions. The phenotype is variable ranging from "near-normal" to a significantly affected individual. In addition, newborns with Klinefelter syndrome generally present with a normal male phenotype and the only consistent clinical finding in KS is small testes, that are most often not identified until after puberty. Decreased awareness of this syndrome among health professionals and a general perception that all patients with 47,XXY exhibit the classic textbook phenotype results in a highly under-diagnosed condition with up to 75% of the patients left undetected. Typically, diagnosis is delayed with the majority of patients identified during fertility workup in adulthood, and only 10% of patients diagnosed prior to puberty. Early detection of this syndrome is recommended in order to offer treatment and intervention at the appropriate ages and stages of development for the purpose of preventing osteopenia/osteoporosis, metabolic syndrome, and other medical conditions related to hypogonadism and to the XXY as well as minimizing potential learning and psychosocial problems. The aim of this review is to present the clinical aspects of XXY and the age-specific recommendations for medical management. © 2013 Wiley Periodicals, Inc.

    Klinefelter syndrome (KS) is the most common sex-chromosome aneuploidy in humans. Most affected individuals carry one extra X-chromosome (47,XXY karyotype) and the condition presents with a heterogeneous mix of reproductive, physical and psychiatric phenotypes. Although the mechanism(s) by which the supernumerary X-chromosome determines these features of KS are poorly understood, skewed X-chromosome inactivation (XCI), gene-dosage dysregulation, and the parental origin of the extra X-chromosome have all been implicated, suggesting an important role for epigenetic processes. We assessed genomic, methylomic and transcriptomic variation in matched prefrontal cortex and cerebellum samples identifying an individual with a 47,XXY karyotype who was comorbid for schizophrenia and had a notably reduced cerebellum mass compared with other individuals in the study (n = 49). We examined methylomic and transcriptomic differences in this individual relative to female and male samples with 46,XX or 46,XY karyotypes, respectively, and identified numerous locus-specific differences in DNA methylation and gene expression, with many differences being autosomal and tissue-specific. Furthermore, global DNA methylation, assessed via the interrogation of LINE-1 and Alu repetitive elements, was significantly altered in the 47,XXY patient in a tissue-specific manner with extreme hypomethylation detected in the prefrontal cortex and extreme hypermethylation in the cerebellum. This study provides the first detailed molecular characterization of the prefrontal cortex and cerebellum from an individual with a 47,XXY karyotype, identifying widespread tissue-specific epigenomic and transcriptomic alterations in the brain.

    This volume documents the preliminary design developed for the Solar Total Energy System to be installed at Fort Hood, Texas. Current system, subsystem, and component designs are described and additional studies which support selection among significant design alternatives are presented. Overall system requirements which form the system design basis are presented. These include program objectives; performance and output load requirements; industrial, statutory, and regulatory standards; and site interface requirements. Material in this section will continue to be issued separately in the Systems Requirements Document and maintained current through revision throughout future phases of the project. Overall system design and detailed subsystem design descriptions are provided. Consideration of operation and maintenance is reflected in discussion of each subsystem design as well as in an integrated overall discussion. Included are the solar collector subsystem; the thermal storage subsystem, the power conversion sybsystem (including electrical generation and distribution); the heating/cooling and domestic hot water subsystems; overall instrumentation and control; and the STES building and physical plant. The design of several subsystems has progressed beyond the preliminary stage; descriptions for such subsystems are therefore provided in more detail than others to provide complete documentation of the work performed. In some cases, preliminary design parameters require specific verificaton in the definitive design phase and are identified in the text. Subsystem descriptions will continue to be issued and revised separately to maintain accuracy during future phases of the project. (WHK)

  20. Reanalysis of multi-temporal aerial images of Storglaciären, Sweden (1959–99 – Part 1: Determination of length, area, and volume changes

    Directory of Open Access Journals (Sweden)

    W. Haeberli

    2010-09-01

    Full Text Available Storglaciären, located in the Kebnekaise massif in northern Sweden, has a long history of glaciological research. Early photo documentations date back to the late 19th century. Measurements of front position variations and distributed mass balance have been carried out since 1910 and 1945/46, respectively. In addition to these in-situ measurements, aerial photographs have been taken at decadal intervals since the beginning of the mass balance monitoring program and were used to produce topographic glacier maps. Inaccuracies in the maps were a challenge to early attempts to derive glacier volume changes and resulted in major differences when compared to the direct glaciological mass balances. In this study, we reanalyzed dia-positives of the original aerial photographs of 1959, -69, -80, -90 and -99 based on consistent photogrammetric processing. From the resulting digital elevation models and orthophotos, changes in length, area, and volume of Storglaciären were computed between the survey years, including an assessment of related errors. Between 1959 and 1999, Storglaciären lost an ice volume of 19×106 m3, which corresponds to a cumulative ice thickness loss of 5.69 m and a mean annual loss of 0.14 m. This ice loss resulted largely from a strong volume loss during the period 1959–80 and was partly compensated during the period 1980–99. As a consequence, the glacier shows a strong retreat in the 1960s, a slowing in the 1970s, and pseudo-stationary conditions in the 1980s and 1990s.

    Full Text Available Analysis of movement of Goc and podgorina population in the second half of XX and on the begging of XXI century is elaborated in the paper. Parameters of natural and mechanical movement of population have showed that population number of Goc and podgorina increase because of mechanical movement. In the period between two last censuses, the greater part of immigrants has arrived. Refugees and outcast population from Ex-Yugoslav Republics represents smaller part of immigrants. Greater part of immigrants belongs to population from others municipalities of Republic of Serbia, especially to population from Kosovo and from municipalities of Raska region. According to the results of exploration, there are many differences in the movements of population between twenty six settlements of Goc and podgorina. As consequences of that, among other, there are some geographic factors. Among geographic factors, traffic-geographic position and relief are relieved. Importance of the paper is that it enriches the knowledge about West Morava valley and Goc, which is northernmost mountain of Kopaonik mountain system.

    We report a case of discordant phenotypic sex in monozygotic twins mosaic 47,XXY/46,XX: monozygotic heterokaryotypic twins. The twins presented with cognitive and comprehension delay, behavioural and language disorders, all symptoms frequently reported in Klinefelter syndrome. Molecular zygosity analysis with several markers confirmed that the twins are in effect monozygotic (MZ). Array comparative genomic hybridization found no evidence for the implication of copy number variation in the phenotypes. Ultrasound scans of the reproductive organs revealed no abnormalities. Endocrine tests showed a low testosterone level in Twin 1 (male phenotype) and a low gonadotrophin level in Twin 2 (female phenotype) which, combined with the results from ultrasound examination, provided useful information for potentially predicting the future fertility potential of the twins. Blood karyotypes revealed the presence of a normal 46,XX cell line and an aneuploïd 47,XXY cell line in both patients. Examination of the chromosome constitutions of various tissues such as blood, buccal smear and urinary sediment not surprisingly showed different proportions for the 46,XX and 47,XXY cell lines, which most likely explains the discordant phenotypic sex and mild Klinefelter features. The most plausible underlying biological mechanism is a post-zygotic loss of the Y chromosome in an initially 47,XXY zygote. This would result in an embryo with both 46,XX and 47,XXY cells lines which could subsequently divide into two monozygotic embryos through a twinning process. The two cell lines would then be distributed differently between tissues which could result in phenotypic discordances in the twins. These observations emphasize the importance of regular paediatric evaluations to determine the optimal timing for fertility preservation measures and to detect new Klinefelter features which could appear throughout childhood in the two subjects.

    Aided by its consultant, the US Geologic Survey (USGS), the Nuclear Regulatory Commission (NRC) reviewed ''Seismic Hazard Methodology for the Central and Eastern United States.'' This topical report was submitted jointly by the Seismicity Owners Group (SOG) and the Electric Power Research Institute (EPRI) in July 1986 and was revised in February 1987. The NRC staff concludes that SOG/EPRI Seismic Hazard Methodology as documented in the topical report and associated submittals, is an acceptable methodology for use in calculating seismic hazard in the Central and Eastern United States (CEUS). These calculations will be based upon the data and information documented in the material that was submitted as the SOG/EPRI topical report and ancillary submittals. However, as part of the review process the staff conditions its approval by noting areas in which problems may arise unless precautions detailed in the report are observed. 23 refs.

    The IFR-1 Test, designated as the AK-181 Test Assembly, will be the first irradiation test of wire wrapped, sodium-bonded metallic fuel elements in the Fast Flux Test Facility (FFTF). The test is part of the Integral Fast Reactor (IFR) fuels program conducted by Argonne National Laboratory (ANL) in support of the Innovative Reactor Concepts Program sponsored by the US Department of Energy (DOE). One subassembly, containing 169 fuel elements, will be irradiated for 600 full power days to achieve 10 at.% burnup. Three metal fuel alloys (U-10Zr, U-8Pu-10Zr) will be irradiated in D9 cladding tubes. The metal fuel elements have a fuel-smeared density of 75% and each contains five slugs. The enriched zone contains three slugs and is 36-in. long. One 6.5-in. long depleted uranium axial blanket slug (DU-10Zr) was loaded at each end of the enriched zone. the fuel elements were fabricated at ANL-W and delivered to Westinghouse-Hanford for wirewrapping and assembly into the test article. This Test Design Description contains relevant data on compositions, densities, dimensions and weights for the cast fuel slugs and completed fuel elements. The elements conform to the requirements in MG-22, "Users` Guide for the Irradiation of Experiments in the FTR."

    This section of the Radioactive Waste Management Complex (RWMC) Part B permit application describes the waste characteristics Of the transuranic (TRU) mixed wastes at the RWMC waste management units to be permitted: the Intermediate-Level Transuranic Storage Facility (ILTSF) and the Waste Storage Facility (WSF). The ILTSF is used to store radioactive remote-handled (RH) wastes. The WSF will be used to store radioactive contact-handled (CH) wastes. The Transuranic Storage Area (TSA) was established at the RWMC to provide interim storage of TRU waste. Department of Energy (DOE) Order 5820.2A defines TRU waste as waste contaminated with alpha-emitting transuranium radionuclides with half-lives greater than 20 years in concentrations greater than 100 nanocuries per gram (nCi/g) o f waste material. The TSA serves generators both on and off the Idaho National Engineering Laboratory (INEL). The ILTSF is located at the TSA, and the WSF will be located there also. Most of the wastes managed at the TSA are mixed wastes, which are radioactive wastes regulated under the Atomic Energy Act (AEA) that also contain hazardous materials regulated under the Resource Conservation and Recovery Act (RCRA) and the Idaho Hazardous Waste Management Regulations. These wastes include TRU mixed wastes and some low-level mixed wastes. Accordingly, the TSA is subject to the permitting requirements of RCRA and the Idaho Administrative Procedures Act (IDAPA). Prior to 1982, DOE orders defined TRU wastes as having transuranium radionuclides in concentrations greater than 10 nCi/g, The low-level mixed wastes managed at the TSA are those wastes with 10 to 100 nCi/g of TRU radionuclides that prior to 1982 were considered TRU waste.

    Full Text Available The twenty-first century has radically changed the concept of leisure. Leisure was conceived to happen only out of working hours. Nowadays we are looking for important experiences during all our lives. The Institute of Leisure Studies of the University of Deusto focuses on the human experience beyond the tangible products. We are witnessing a major cultural change in the developed world where most of the population has turned into a philosophy that could be summed up as “having less, enjoying more”. At the same time, the TIC’S revolution has propitiated a deep change in the field of the cultural leisure through new areas as consumer electronics –with its greatest exponent: video games– and virtual communities. Leisure, as a result, has become a significant economic sector with a brilliant future. We are trying to address in this article its impact in terms of production, employment and income.

  17. Design of an Image-Servo Mask Alignment System Using Dual CCDs with an XXY Stage

    2016-02-01

    Full Text Available Mask alignment of photolithography technology is used in many applications, such as micro electro mechanical systems’ semiconductor process, printed circuits board, and flat panel display. As the dimensions of the product are getting smaller and smaller, the automatic mask alignment of photolithography is becoming more and more important. The traditional stacked XY-Θz stage is heavy and it has cumulative flatness errors due to its stacked assembly mechanism. The XXY stage has smaller cumulative error due to its coplanar design and it can move faster than the traditional XY-Θz stage. However, the relationship between the XXY stage’s movement and the commands of the three motors is difficult to compute, because the movements of the three motors on the same plane are coupling. Therefore, an artificial neural network is studied to establish a nonlinear mapping from the desired position and orientation of the stage to three motors’ commands. Further, this paper proposes an image-servo automatic mask alignment system, which consists of a coplanar XXY stage, dual GIGA-E CCDs with lens and a programmable automatic controller (PAC. Before preforming the compensation, a self-developed visual-servo provides the positioning information which is obtained from the image processing and pattern recognition according to the specified fiducial marks. To obtain better precision, two methods including the center of gravity method and the generalize Hough Transformation are studied to correct the shift positioning error.

  18. Solar Flare Termination Shock and the Synthetic Fe XXI 1354.08 Å line

    Science.gov (United States)

    Guo, Lijia; Li, Gang; Reeves, Kathy

    2017-08-01

    Solar flares are one of the most energetic phenomena occurred in the solar system. In the standard solar flare model, a fast mode shock, which is often referred to as the flare termination shock (TS), can exist above the loop-top source of hard X-ray emissions. The existence of the termination shock has been recently related to spectral hardening of flare hard X-ray spectrum at energies > 300 keV. Observations of the Fe XXI 1354.08 Å line during solar flares by the IRIS spacecraft have found significant redshift with >100 km/s, which is consistent with a reconnection downflow. The ability to identify such a redshift by IRIS is made possible by IRIS's high time resolution, high spatial resolution, high sensitivity and cadence spectral observations. The ability to identify such a redshift by IRIS suggests that one may be able to use IRIS observations to identify flare termination shocks. Using an MHD simulation to model magnetic reconnection of a solar flare and assuming the existence of a TS in the downflow of the reconnection plasma, we model the synthetic emission of the Fe XXI 1354.08 Å line in this work. We show that the existence of the TS in the solar flare may manifest itself from the Fe XXI 1354.08 Å line.

    We report the case of a 12.4-yr-old boy who presented Klinefelter syndrome (KS) mosaicism (46,XY/47,XXY), associated with mental retardation and anorexia nervosa (AN). KS was undiagnosed before hospitalization in a psychiatric unit. The patient was referred to a child psychiatric unit for restrictive eating. The medical history showed long standing feeding difficulties and failure to thrive. The patient was pre-pubertal and other clinical characteristics were: microcephaly, short stature and dysmorphic traits. Cytogenetic analysis revealed a mosaicism, 46,XY[11] and 47,XXY[19] karyotype. The psychiatric assessment demonstrated the presence of AN and low mood. No specific pathophysiological links between the alterations of KS and the development of AN should be hypothesized on the basis of this case report. In pre-pubertal boys with mental disorders, the possibility of KS should be considered, independently of the presence of eating disorders. Nevertheless, the case shows that KS can be first detected during an assessment for eating disorders. Few cases of the association of KS with AN have been previously reported in literature. This is the first description of KS, mosaicism (46,XY/47,XXY), associated with AN and mental retardation. This case report illustrates the need, for clinicians who work with eating disorders, to investigate the possible association between AN and KS, a rare but intriguing one.

La existencia de largometrajes como el citado pone en el horizonte social un debate que desde una perspectiva feminista se vuelve trascendente si consideramos que las producciones cinematográficas son una manera del decir social, de imponer normas en relación a lo posible y lo imposible, en este caso sobre la constitución del sujeto sexuado.This work takes as a narrative excuse the Argentinean film XXY to discuss some aspects the film brings to the fore about the social and cultural construction of the sexual body, and how this construction has implications in the particular ways to experience the body and sexuality. The pivot of this analysis will be the concept of "stigma". The existence of this kind of film raises debate which, from a feminist perspective, has a vital meaning if we consider that filmic productions impose norms about what is possible and what is not, in this case about the constitution of a sexed subject.

    2015-05-01

    Full Text Available In this study, a novel laser direct synthesis and pattering technology is applied in conjunction with an A&F XXY alignment platform to rapidly fabricate flexible conductors on a polymer substrate (polyimide film with designated patterns. In the process, a focused continuous wave green laser was focused onto the polymer substrate that is mounted and directed using the XXY alignment platform. The focused laser energy absorbed by the polymer substrate is used to heat the transparent and particle-free reactive silver ink on the polymer substrate surface. With appropriate programing of the XXY alignment platform motion to control the laser scanning parameters, silver patterns with good electrical conductivity were successfully obtained. This technology can be operated directly at atmospheric pressure and room temperature. It does not require the use of vacuum chamber, oven and photo-mask, etc. Therefore, this novel technology and system offers a new approach to the cost-effective and green fabrication for flexible electronics. The compact size and excellent stability of the XXY alignment platform make the fabrication system even more competitive. In particular, the programmable small radius plane rotation function of the XXY alignment platform provides flexibility in the pattern design with turnings while keeps the uniformity of the resulted micro metal lines.

  7. Expression of selected genes escaping from X inactivation in the 41, XX(Y)* mouse model for Klinefelter's syndrome.

    We hypothesized that patients with Klinefelter's syndrome (KS) not only undergo X inactivation, but also that genes escape from inactivation. Their transcripts would constitute a significant difference, as male metabolism is not adapted to a 'female-like' gene dosage. We evaluated the expression of selected X-linked genes in our 41, XX(Y)* male mice to determine whether these genes escape inactivation and whether tissue-specific differences occur. Correct X inactivation was identified by Xist expression. Relative expression of X-linked genes was examined in liver, kidney and brain tissue by real-time PCR in adult XX(Y)* and XY* males and XX females. Expression of genes known to escape X inactivation was analysed. Relative mRNA levels of Pgk1 (control, X inactivated), and the genes Eif2s3x, Kdm5c, Ddx3x and Kdm6a escaping from X inactivation were quantified from liver, kidney and brain. Pgk1 mRNA expression showed no difference, confirming correct X inactivation. In kidney and liver, XX(Y)* males resembled the female expression pattern in all four candidate genes and were distinguishable from XY* males. Contrastingly, in brain tissue XX(Y)* males expressed all four genes higher than male and female controls. Altered expression of genes escaping X inactivation probably contributes directly to the XX(Y)* phenotype. © 2011 The Author(s)/Acta Paediatrica © 2011 Foundation Acta Paediatrica.

  13. Social Attention in 47,XXY (Klinefelter Syndrome): Visual Scanning of Facial Expressions Using Eyetracking.

    2015-05-01

    Boys and men with an extra X chromosome (47,XXY, Klinefelter syndrome) are at risk for problems in social functioning and have an increased vulnerability for autism spectrum disorders (ASD). In the search for underlying mechanisms driving this increased risk, this study focused on social attention, that is, spontaneous orientation toward facial expressions. Seventeen adults with 47,XXY and 20 non-clinical controls participated in this study. Social attention was measured using an eyetracking method that quantifies the visual scanning patterns of faces expressing different types of emotions (happy, fearful, angry, neutral) and their varying intensity levels (25%, 50%, 75%, 100%). Overall, the group with Klinefelter syndrome fixated less on the eye region of faces when compared to controls (Cohen's d 1.4), and did not show the typical tendency, as was found in the control group, to first fixate on the eyes when presented with a face (Cohen's d 1.0). There was no significant effect of type or intensity of emotion. Shorter looking times toward eyes showed a borderline significant correlation with self-reports of poorer social functioning, with 29% explained variance. These findings suggest a reduced tendency to rapidly and automatically attend to the eyes of others in individuals with 47,XXY. This may have impact on more complex social-cognitive abilities that build upon this. In addition to studies of behaviorally defined disorders such as ASD, studying individuals with Klinefelter syndrome provide insight into mechanisms underlying various "at risk" pathways of social dysfunction and the factors that mediate this risk.

    1993-02-26

    The Oak Ridge K-25 Technology Logic Diagram (TLD), a decision support tool for the K-25 Site, was developed to provide a planning document that relates environmental restoration (ER) and waste management (WN) problems at the Oak Ridge K-25 Site. The TLD technique identifies the research necessary to develop these technologies to a state that allows for technology transfer and application to waste management, remediation, decontamination, and decommissioning activities. The TLD consists of four separate volumes-Vol. 1, Vol. 2, Vol. 3A, and Vol. 3B. Volume 1 provides introductory and overview information about the TLD. Volume 2 contains logic diagrams. Volume 3 has been divided into two separate volumes to facilitate handling and use. This volume 3 B provides the Technology Evaluation Data Sheets (TEDS) for ER/WM activities (Remedial Action Robotics and Automation, Waste Management) that are referenced by a TEDS code number in Vol. 2 of the TLD. Each of these sheets represents a single logic trace across the TLD. These sheets contain more detail than each technology in Vol. 2. The TEDS are arranged alphanumerically by the TEDS code number in the upper right corner of each data sheet. Volume 3 can be used in two ways: (1) technologies that are identified from Vol. 2 can be referenced directly in Vol. 3 by using the TEDS codes, and (2) technologies and general technology areas (alternatives) can be located in the index in the front of this volume.

    Full Text Available Streamflows in five Mediterranean mountain headwaters in the central Spanish Pyrenees were projected under various climate and land use change scenarios. Streamflows were simulated using the Regional Hydro-Ecologic Simulation System (RHESSys. The results show that changes in precipitation and temperature could cause a decline of annual streamflow between 13% and 23%, depending on the considered catchment. When the effect of increased forest cover in the basins is added to climate change effects, the decrease in annual streamflow is enhanced up to 19% and 32%. The largest hydrological changes resulting from environmental change are projected mainly in early spring, summer and autumn, when the decline may exceed 40%. Winter is the least affected season by environmental change because of increased runoff as a consequence of reduced storage of water in the snowpack and an earlier onset of the snowmelt, and the lower consumption of water by vegetation during the cold season. The magnitude of hydrological change as a result of the assumed environmental change scenarios may lead to serious impacts on water management and ecology of the studied region, as well as the water availability in the Ebro basin.Se han simulado los caudales de cinco cabeceras de ríos en los Pirineos centrales españoles, considerando diferentes escenarios de cambio climático y de uso del suelo.

  11. Vision Servo Motion Control and Error Analysis of a Coplanar XXY Stage for Image Alignment Motion

    Directory of Open Access Journals (Sweden)

    Hau-Wei Lee

    2013-01-01

    Full Text Available In recent years, as there is demand for smart mobile phones with touch panels, the alignment/compensation system of alignment stage with vision servo control has also increased. Due to the fact that the traditional stacked-type XYθ stage has cumulative errors of assembly and it is heavy, it has been gradually replaced by the coplanar stage characterized by three actuators on the same plane with three degrees of freedom. The simplest image alignment mode uses two cameras as the equipments for feedback control, and the work piece is placed on the working stage. The work piece is usually engraved/marked. After the cameras capture images and when the position of the mark in the camera is obtained by image processing, the mark can be moved to the designated position in the camera by moving the stage and using alignment algorithm. This study used a coplanar XXY stage with 1 μm positioning resolution. Due to the fact that the resolution of the camera is about 3.75 μm per pixel, thus a subpixel technology is used, and the linear and angular alignment repeatability of the alignment system can achieve 1 μm and 5 arcsec, respectively. The visual servo motion control for alignment motion is completed within 1 second using the coplanar XXY stage.

    We report a 4-year-old hyperactive, mentally retarded male with 47,XXY and UPD for fra(X). Speech and motor delay were first noted at age 15 months. He has no dysmorphic features, normal ears, hyperextensible joints, small testes, and no history of seizures. His mother has prominent lowest ears, a long midface, anteverted nostrils, hyperextensible joints, malocclusion, and had learning problems in school. Routine chromosome analysis revealed the proband to be 47,XXY. Parental chromosomes were normal in number. The proband was fra(X) positive [30/160 cells, 18%]. No cells had two expressed fra(X)s; however, this may be a function of the low level of expression and the number of cells scored. Maternal cells were also fra(X) positive [19/205, 9.2%]. Southern analysis demonstrated the mother to be heterozygous for a methylated, full mutation (>220 repeats); her normal FMR-1 gene was disproportionately unmethylated. The proband had two fully expanded and methylated FMR-1 genes, one the same size as the maternal gene and the other >620 repeats. RFLP analysis revealed a maternal meiotic II error, the result of which was UPD of the X chromosome.

    . The second approach, which is more typically meteorological, relies on the calculation of the E for the time frame 2071-2100 by using the previous coefficients. On the basis of the assessment of climate units in the XXI century and with help of the established relationships, the water flow of Danube river and runoff depth were defined for this century. The results according to this model, show that the river flow of the Danube, in this part of its basin, will decrease over 50% with a great consequences to the dams Iron Gate I and II, their accumulations and ecosystems. Furthermore, if we take into account predictions made by IPCC which say that the south-east Europe will face temperature growth of 0.2 degrees in the next two decades for the range of SRES scenarios, makes the whole problem much more complicated and alarming. Results also show that precipitation's peak in the early summer months and in November, which gives more often a secondary maximum, is the typical feature of the observed climatology of the precipitation of the Danubian region. The minima of precipitation are also clustered in two periods of the year, namely February and the summer months. The latter minimum is a signature of the influence of the typical Mediterranean summer. As an output of all that, as has been mentioned above, this part of Europe will face with worse conditions (high temperatures, droughts) in a region already vulnerable to climate variability, than those of 2003 when Europe was hit by an incredible heat wave. Reductions of water availability, hydropower potential, summer tourism and general crop productivity are certainly appearances which are to be expected in this area. In turns of the results, one question has arisen: Should we adapt to the climate change, or should we mitigate it? Maybe, the answer is in mitigation while doing adaptation. According to the Danube river in this region, the works for fighting reservoir related bank erosion in order to preserve the dam and

    With an incidence of approximately 1 in 500 male newborns, the 47,XXY genotype is one the most common sex chromosome anomalies. It is also the most frequent genetic cause of human infertility. Some non-mosaic 47,XXY patients have sperm production which allows infertility treatment to be offered by ICSI. Therefore, the risk of transmitting a chromosome anomaly to the next generation is an important problem in reproductive genetic counselling of these patients. Here, we report on a twin pregnancy where two karyotypically normal neonates 46,XX and 46,XY were born after the use of ICSI in assisted reproduction of a patient with a non-mosaic 47,XXY syndrome. To date, only 38 evolving pregnancies including the present cases, have been reported after ICSI using sperm from non-mosaic 47,XXY patients. Although these data are scarce, they suggest that the risk of chromosome anomaly in the offspring of these patients is low; hence, their reproductive genetic counselling can be reassuring, and management of the pregnancy can proceed with caution.

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).

    SCALE--a modular code system for Standardized Computer Analyses Licensing Evaluation--has been developed by Oak Ridge National Laboratory at the request of the US Nuclear Regulatory Commission. The SCALE system utilizes well-established computer codes and methods within standard analysis sequences that (1) allow an input format designed for the occasional user and/or novice, (2) automate the data processing and coupling between modules, and (3) provide accurate and reliable results. System development has been directed at problem-dependent cross-section processing and analysis of criticality safety, shielding, heat transfer, and depletion/decay problems. Since the initial release of SCALE in 1980, the code system has been heavily used for evaluation of nuclear fuel facility and package designs. This revision documents Version 4.2 of the system. The manual is divided into three volumes: Volume 1--for the control module documentation, Volume 2--for functional module documentation; and Volume 3--for documentation of the data libraries and subroutine libraries. This volume discusses the following functional modules: MORSE-SGC; HEATING 7.2; KENO V.a; JUNEBUG-II; HEATPLOT-S; REGPLOT 6; PLORIGEN; and OCULAR.

    Full Text Available Se realiza una actualización de las enfermedades infecciosas emergentes y reemergentes, por la importancia que ellas revisten en el presente siglo al nivel mundial. Se señala la importancia que tienen para los estudiantes de medicina en Cuba, por lo que debe impartirse esta temática desde los primeros años de la carrera, cuando ellos entren al área clínica. De esta forma adquirirán los conocimientos necesarios para poder realizar el diagnóstico de sospecha cuando se encuentren realizando su trabajo profesional tanto en Cuba como en cualquier otro país. Se definen éstas y se hace un recuento de su aparición cronológica, bien por el descubrimiento de los agentes causales ya sean bacterias, virus o parásitos y las enfermedades que ocasionan. Posteriormente se procede a describir las causas posibles de su emergencia o reemergencia y se destaca entre ellas: los cambios ecológicos, el desarrollo de la agricultura, los cambios demográficos y su conducta, el comercio y los viajes internacionales, la tecnología y la industria, la adaptación microbiana y sus cambios y el fracaso en las medidas de salud pública. Se realiza un breve recuento de la repercusión que han tenido estas enfermedades en nuestra América y con referencia a Cuba.An updating is made on the emerging and re-emerging infectious diseases because of their importance worldwide in the present century. The importance of such diseases for medical students in Cuba is also stated since this subject should be taught in the first years of medical studies when the students begin their practice in the clinical area. In this way, they will acquire the necessary knowledge that will enable them to make a suspicion diagnosis when they carry out their professional work both in Cuba and any other part of the world. These diseases are defined along with their chronological occurrence either by the discovery of the causative agents (bacteria, virus or parasites or the diseases caused

    The overall task of this program was to provide an assessment of currently available technology for treating commercial low-level radioactive waste (LLRW), to initiate development of a methodology for choosing one technology for a given application, and to identify research needed to improve current treatment techniques and decision methodology. The resulting report is issued in four volumes. Volume 3 of this series is a collection of abstracts of most of the reference documents used for this study. Because of the large volume of literature, the abstracts have been printed in two separate parts. Volume 3, part 1 presents abstracts of the open literature relating to LLRW treatment methodologies. Some of these references pertain to treatment processes for hazardous wastes that may also be applicable to LLRW management. All abstracts have been limited to 21 lines (for brevity), but each abstract contains sufficient information to enable the reader to determine the potential usefulness of the source document and to locate each article. The abstracts are arranged alphabetically by author or organization, and indexed by keyword.

    1976-01-01

    A pyrex glass plate was fitted at the bottom of casting ring, and disk type wax pattern (thickness. 0.43 mm) was put on the plate. Five types of sprueing were applied. Pure tin was casted using holizontal centrifugal casting machine. Flow of molten metal was filmed by the motor drive camera with the method of stroboscope. The results were summarized as follows. 1) When the sprue was attached at the center of the disk type mold vertically, moten metal flowed like a concentric circle at the early stage of casting. It was affected gradually by the direction of gravity and revolution, and it filled the mold from the lower part to the upper part. 2) When the sprue gate was attached to the side edge of the mold, and the sprue gate was placed to the forward and backward direction against the revolution direction, molten metal filled from lower part to the upper part. 3) When the sprue gate was placed against upper edge, molten metal flow was affected by the direction of gravity and revolution. When the sprue gate was placed against lower edge, molten metal filled quietry from the lower part to the upper part. 4) Inflow volume per unit time (inflow rate) was small at the early stage of casting. Inflow rate increased and became constant at the next stage. At the latter stage it became small again. 5) Inflow rate increased with the increase of area of sprue. 6) The time which was necessary to fill the volume of 1 cm (about 80% of the mold volume) became short with the increase of area of sprue. It was also influenced by the type of sprueing.

    2011-01-01

    The volumes in this authoritative series present a multidisciplinary approach to modeling and simulation of flows in the cardiovascular and ventilatory systems, especially multiscale modeling and coupled simulations. The cardiovascular and respiratory systems are tightly coupled, as their primary function is to supply oxygen to and remove carbon dioxide from the body's cells. Because physiological conduits have deformable and reactive walls, macroscopic flow behavior and prediction must be coupled to nano- and microscopic events in a corrector scheme of regulated mechanisms. Therefore, investigation of flows of blood and air in physiological conduits requires an understanding of the biology, chemistry, and physics of these systems together with the mathematical tools to describe their functioning.  The present volume is devoted to cellular events that allow adaptation to environmental conditions, particularly mechanotransduction. It begins with cell organization and a survey of cell types in the vasculatur...

  6. Communication Strategy of Transboundary Air Pollution Findings in a US-Mexico Border XXI Program Project

    Mukerjee, Shaibal

    2002-01-01

    From 1996 to 1997, the US Environmental Protection Agency (EPA) and the Texas Natural Resource Conservation Commission (TNRCC) conducted an air quality study known as the Lower Rio Grande Valley Transboundary Air Pollution Project (TAPP). The study was a US-Mexico Border XXI program project and was developed in response to local community requests on a need for more air quality measurements and concerns about the health impact of local air pollutants; this included concerns about emissions from border-dependent industries in Mexico, known as maquiladoras. The TAPP was a follow-up study to environmental monitoring done by EPA in this area in 1993 and incorporated scientific and community participation in development, review of results, and public presentation of findings. In spite of this, critical remarks were leveled by community activists against the study's preliminary "good news" findings regarding local air quality and the influence of transboundary air pollution. To resolve these criticisms and to refine the findings to address these concerns, analyses included comparisons of daily and near real-time measurements to TNRCC effects screening levels and data from other studies along with wind sector analyses. Reassessment of the data suggested that although regional source emissions occurred and outliers of elevated pollutant levels were found, movement of air pollution across the border did not appear to cause noticeable deterioration of air quality. In spite of limitations stated to the community, the TAPP was presented as establishing a benchmark to assess current and future transboundary air quality in the Valley. The study has application in Border XXI Program or other air quality studies where transboundary transport is a concern since it involved interagency coordination, public involvement, and communication of scientifically sound results for local environmental protection efforts.

    This data manual contains a hard copy of the information in the Nuclear Computerized Library for Assessing Reactor Reliability (NUCLARR) Version 3.5 database, which is sponsored by the US Nuclear Regulatory Commission. NUCLARR was designed as a tool for risk analysis. Many of the nuclear reactors in the US and several outside the US are represented in the NUCLARR database. NUCLARR includes both human error probability estimates for workers at the plants and hardware failure data for nuclear reactor equipment. Aggregations of these data yield valuable reliability estimates for probabilistic risk assessments and human reliability analyses. The data manual is organized to permit manual searches of the information if the computerized version is not available. Originally, the manual was published in three parts. In this revision the introductory material located in the original Part 1 has been incorporated into the text of Parts 2 and 3. The user can now find introductory material either in the original Part 1, or in Parts 2 and 3 as revised. Part 2 contains the human error probability data, and Part 3, the hardware component reliability data.

    Full Text Available People have always built temples. Their diversity is infinite. Majestic cathedrals and mosques made of eternal stones neighbor a cardboard cathedral built by Pritzker laureate Shigeru Ban after the earthquake in New Zealand. Avantgarde experiments of new religions emerging in front of our eyes and no less surprising experiences of Catholic temples are side by side with an age-long strong tradition of Orthodox churches.After seventy years of gap thousands of temples of different confessions have been built and restored in the post-Soviet area. This issue includes projects of new religious buildings in Buryatia and Zabaikalie, Irkutsk and Angarsk, Krasnoyarsk, Kuzbass and Altai.The rise of construction of temples raises a lot of questions. Debates on a new appearance of churches develop simultaneously with discussions on the necessity of a new translation of the Bible into the modern language. The Union of Architects of Russia with the support of the Moscow Patriarchate of the Russian Orthodox Church launched a competition inviting ideas for a modern image of an Orthodox temple. The dogmata are unchanged, but the canons can be changed in time, as clergy members say. But how deep can such changes be? In what direction should the temple architecture develop? What is the best way for it to meet the challenges of our time, the changing lifestyle, the new rhythms and means of world perception?Again we fill our journal with questions to think them over together with our clever and nonindifferent reader.

Fe XXI appears at all of the chromospheric ribbon sites, although typically with a delay of one raster (75 s) and sometimes offset by up to 1''. 100-200 km s{sup –1} blue-shifts are found at the brightest ribbons, suggesting hot plasma upflow into the corona. The Fe XXI ribbon emission is compact with a spatial extent of <2'', and can extend beyond the chromospheric ribbon locations. Examples are found of both decreasing and increasing blue-shift in the direction away from the ribbon locations, and blue-shifts were present for at least six minutes after the flare peak. The post-flare loop arcade, seen in Atmospheric Imaging Assembly 131 Å filtergram images that are dominated by Fe XXI, exhibited bright loop-tops with an asymmetric intensity distribution. The sizes of the loop-tops are resolved by IRIS at ≥1'', and line widths in the loop-tops are not broader than in the loop-legs suggesting the loop-tops are not sites of enhanced turbulence. Line-of-sight speeds in the loop arcade are typically <10 km s{sup –1}, and mean non-thermal motions fall from 43 km s{sup –1} at the flare peak to 26 km s{sup –1} six minutes later. If the average velocity in the loop arcade is assumed to be at rest, then it implies a new reference wavelength for the Fe XXI line of 1354.106 ± 0.023 Å.

Todo el quehacer museal se orienta a satisfacer los gustos y necesidades del sujeto-visitante para así atraerlo al Museo. Este nuevo enfoque museológico tiene el riesgo de olvidar el objeto en el proceso educativo y centrarse en el sujeto. Se propone la promoción del diálogo sujeto-objeto para que la función educativa del Museo contribuya a la conformación de una sociedad con conciencia histórica-cultural clara. Se concluye que, en las primeras décadas del Siglo XXI los diferentes enfoques de la sociomuselogía, la museografía interactiva, la museología crítica y dialógica, así como los ejes de cambio generados por las innovaciones tecnológicas, las dinámicas de consumo y las comunidades de aprendizaje, apuntan a que la audiencia es el centro de atención, y no el objeto y la forma de ser expuesto como lo fue en el Siglo XX.Abstract: This paper presents an allegory between the muses of Greek mythology as the inspiration of memory, knowledge and the arts and the role of muses in inspiring current museum's tasks in the twenty-first century on the worldwide stage, in order to systematize the emerging museological XXI century currents and the central axes of change that are developing in this period. It concludes that in this century different museological approaches to sociomuseology, interactive museography and critical dialogical museology as well as the axes of change generated by technological innovations, the dynamics of consumption and learning communities, suggest that the individual visitor is the main target, and not the object and how it is exhibited (as in the last century.

    Two types of spruing methods were used in the casting of the denture type model pattern (thickness, 0.43 mm). Flow of molten metal in the mold was filmed by the improved system of Part 1. When three sprues were attached to the pattern vertically, molten metal passed through each sprue gate flowed being affected by the direction of gravity and revolution of casting machine, and gathered at the lower part of the mold. Next molten metal filled the mold from the lower part to the upper part. In this spruing type, molten metal turned its direction of flow several times. At the middle stage of casting, the inflow volume per unit time (inflow rate), v (mm3/10-2)s)was evaluated as v = 12.36 + 5.16A-0.16 A2 (A: total cross-sectional areas of sprues). The inflow rate increased with increase of the area of the sprues, but it saturated. When the main sprue and the subsprues were attached at the posterior border, the molten metal filled the mold from the lower part to the upper part quietly. In this spruing type, the casting mold was set facing its sprue gates downwards. The inflow rate at the middle stage of casting was evaluated as v = 21.05 + 1.79 C (C: the cross-sectional area of the main sprue). The inflow rate increased linearly with increase of the area of the main sprue.

    Traditionally, probabilistic risk assessments (PRA) of severe accidents in nuclear power plants have considered initiating events potentially occurring only during full power operation. Some previous screening analyses that were performed for other modes of operation suggested that risks during those modes were small relative to full power operation. However, more recent studies and operational experience have implied that accidents during low power and shutdown could be significant contributors to risk. Two plants, Surry (pressurized water reactor) and Grand Gulf (boiling water reactor), were selected as the plants to be studied. The objectives of the program are to assess the risks of severe accidents initiated during plant operational states other than full power operation and to compare the estimated core damage frequencies, important accident sequences and other qualitative and quantitative results with those accidents initiated during full power operation as assessed in NUREG-1150. The scope of the program includes that of a level-3 PRA. In phase 2, mid-loop operation was selected as the plant configuration to be analyzed based on the results of the phase 1 study. The objective of the phase 2 study is to perform a detailed analysis of the potential accident scenarios that may occur during mid-loop operation, and compare the results with those of NUREG-1150. The scope of the level-1 study includes plant damage state analysis, and uncertainty analysis. Volume 1 summarizes the results of the study. Internal events analysis is documented in Volume 2. It also contains an appendix that documents the part of the phase 1 study that has to do with POSs other than mid-loop operation. Internal fire and internal flood analyses are documented in Volumes 3 and 4. A separate study on seismic analysis, documented in Volume 5, was performed for the NRC by Future Resources Associates, Inc. Volume 6 documents the accident progression, source terms, and consequence analysis.

El tratamiento metodológico parte del planteamiento de la premisa: el Nuevo Modelo de Educación Universitaria que está por construirse, se debe a la crisis del modelo cognitivo instrumental instituido en la Constitución de la República de Venezuela (1961, sus Leyes y Reglamentos. Al triangular las tres categorías se plantea, como valor agregado, concebir la educación a través de un proceso transdisciplinario, sustentado en una primera instancia por el ordenamiento jurídico que le dé concreción y sincronización en el tiempo y el movimiento. En el caso de la educación venezolana, se concluye que no se han producidos cambios significativos que nos indiquen que estamos en presencia de un nuevo modelo de educación. La educación universitaria sigue atada al modelo cognitivo instrumental, impidiendo cualquier cambio que desde su seno se pretenda impulsar, de manera que la nueva Ley de Educación Universitaria y el nuevo modelo de educación siguen diferido.

    Adult sagittal posture is established during childhood and adolescence. A flattened or hypercurved spine is associated with poorer musculoskeletal health in adulthood. Although anthropometry from birth onwards is expected to be a key influence on sagittal posture design, this has never been assessed during childhood. Our aim was to estimate the association between body size throughout childhood with sagittal postural patterns at age 7. Prospective cohort study. A subsample of 1029 girls and 1101 boys taking part in the 7-year-old follow-up of the birth cohort Generation XXI (Porto, Portugal) was included. We assessed the associations between anthropometric measurements (weight, height and body mass index) at birth, 4 and 7 years of age and postural patterns at age 7. Postural patterns were defined using latent profile analysis, a probabilistic model-based technique which allows for simultaneously including anthropometrics as predictors of latent profiles by means of logistic regression. Postural patterns identified were sway, flat and "neutral to hyperlordotic"in girls, and "sway to neutral", flat and hyperlordotic in boys; with flat and hyperlordotic postures representing a straightened and a rounded spine, respectively. In both girls and boys, higher weight was associated with lower odds of a flat pattern compared with a sway/"sway to neutral"pattern, with stronger associations at older ages: for example, ORs were 0.68 (95% CI 0.53 to 0.88) per SD increase in birth weight and 0.36 (95% CI 0.19 to 0.68) per SD increase in weight at age 7 in girls, with similar findings in boys. Boys with higher ponderal index at birth were more frequently assigned to the hyperlordotic pattern (OR=1.44 per SD; p=0.043). Our findings support a prospective sculpting role of body size and therefore of load on musculoskeletal spinopelvic structures, with stronger associations as children get older. © Article author(s) (or their employer(s) unless otherwise stated in the text of the

    Jorge Raúl Jorrat

    2013-01-01

    Full Text Available La abstención electoral ha sido un tema de preocupación tanto en la vida política argentina como en los estudios internacionales sobre el tema. Para etapas tempranas la prensa y la dirigencia política local se preocupaba por la posibilidad de que “la mejor gente” –supuestamente alejada de la vida cívica- no concurriera a las urnas. Respecto de tales etapas, Canton y Jorrat rechazaron empíricamente la visión impresionista de que en la ciudad de Buenos Aires la “mejor gente” no votaba. Lijphart exhibía preocupaciones de este tipo, señalando luego que la evidencia empírica mostraba correlaciones positivas entre nivel socioeconómico y concurrencia a las urnas. Parte de esas preocupaciones habrían conducido a la obligatoriedad del voto en el país. En el presente trabajo extendemos nuestra indagación a datos de nivel individual, a partir de una encuesta nacional de 3300 casos en 2007. Vía ecuaciones de regresión logística, se explora la vinculación del no voto en las elecciones presidenciales de 1995, 1999 y 2003 con variables sociodemográficas clásicas (sexo, edad, educación, explorando la importancia explicativa comparada de variables consideradas estratégicas en la literatura: tradición electoral, identificación ideológica, valores sociales (materialismo, clase social, etc. Una mirada adicional final se ofrece para datos agregados de las elecciones de diputados de 2009 en la ciudad de Buenos Aires. Los resultados, tanto descriptivos como de regresiones logísticas de la encuesta nacional, o de correlaciones simples y regresiones lineales múltiples para los datos agregados de la ciudad de Buenos Aires, mostrarían la ausencia de clivajes sociales marcados y sistemáticos tanto para fines del siglo XX como comienzos del XXI. Lo que apoyaría la posición de Lijphart, cuando sostiene que el voto obligatorio podría ser un mecanismo para promover el uso casi universal del derecho del voto.

    Attentional problems, hyperactivity, and impulsivity have been described as behavioral features associated with sex chromosome aneuploidy (SCA). In this study, the authors compare attention-deficit hyperactivity disorder (ADHD) symptoms in 167 participants aged 6 to 20 years with 4 types of SCA (XXY n = 56, XYY n = 33, XXX n = 25, and XXYY n = 53). They also evaluate factors associated with ADHD symptomatology (cognitive and adaptive scores, prenatal vs postnatal ascertainment) and describe the clinical response to psychopharmacologic medications in a subset of patients treated for ADHD. Evaluation included medical and developmental history, cognitive and adaptive functioning assessment, and parent and teacher ADHD questionnaires containing DSM-IV criteria. In the total study group, 58% (96/167) met DSM-IV criteria for ADHD on parent-report questionnaires (36% in XXY, 52% in XXX, 76% in XYY, and 72% in XXYY). The Inattentive subtype was most common in XXY and XXX, whereas the XYY and XXYY groups were more likely to also have hyperactive/impulsive symptoms. There were no significant differences in Verbal, Performance, or Full Scale IQ between children with symptom scores in the ADHD range compared with those below the ADHD range. However, adaptive functioning scores were significantly lower in the group whose scores in the ADHD range were compared with those of the group who did not meet ADHD DSM-IV criteria. Those with a prenatal diagnosis of XXY were less likely to meet criteria for ADHD compared with the postnatally diagnosed group. Psychopharmacologic treatment with stimulants was effective in 78.6% (66/84). Children and adolescents with SCA are at increased risk for ADHD symptoms. Recommendations for ADHD evaluation and treatment in consideration of other aspects of the SCA medical and behavioral phenotype are provided.

    2014-11-01

    Full Text Available The collision fault detection of a XXY stage is proposed for the first time in this paper. The stage characteristic signals are extracted and imported into the master and slave chaos error systems by signal filtering from the vibratory magnitude of the stage. The trajectory diagram is made from the chaos synchronization dynamic error signals E1 and E2. The distance between characteristic positive and negative centers of gravity, as well as the maximum and minimum distances of trajectory diagram, are captured as the characteristics of fault recognition by observing the variation in various signal trajectory diagrams. The matter-element model of normal status and collision status is built by an extension neural network. The correlation grade of various fault statuses of the XXY stage was calculated for diagnosis. The dSPACE is used for real-time analysis of stage fault status with an accelerometer sensor. Three stage fault statuses are detected in this study, including normal status, Y collision fault and X collision fault. It is shown that the scheme can have at least 75% diagnosis rate for collision faults of the XXY stage. As a result, the fault diagnosis system can be implemented using just one sensor, and consequently the hardware cost is significantly reduced.

  7. Solar Flare Termination Shock and Synthetic Emission Line Profiles of the Fe xxi 1354.08 Å Line

    2017-09-01

    Solar flares are among the most energetic phenomena that occur in the solar system. In the standard solar flare model, a fast mode shock, often referred to as the flare termination shock (TS), can exist above the loop-top source of hard X-ray emissions. The existence of the TS has been recently related to spectral hardening of a flare’s hard X-ray spectra at energies >300 keV. Observations of the Fe xxi 1354.08 Å line during solar flares by the Interface Region Imaging Spectrograph (IRIS) spacecraft have found significant redshifts with >100 km s‑1, which is consistent with a reconnection downflow. The ability to detect such a redshift with IRIS suggests that one may be able to use IRIS observations to identify flare TSs. Using a magnetohydrodynamic simulation to model magnetic reconnection of a solar flare and assuming the existence of a TS in the downflow of the reconnection plasma, we model the synthetic emission of the Fe xxi 1354.08 line in this work. We show that the existence of the TS in the solar flare may manifest itself in the Fe xxi 1354.08 Å line.

    Full Text Available Os conflitos que inauguram o século XXI dão a impressão de que a paz é um objetivo quase inatingível. Diante das novas ameaças, nada faz crer que o terror provocado pela guerra fria encontre-se superado. Ao lado das formas tradicionais de luta, uma guerra quase surda eclode no seio das sociedades. A fome, por exemplo, é uma arma que mata em silêncio, e a violência e a miséria revelam que o estado de natureza persiste. A questão que se coloca, então é a seguinte: é possível falar em paz pensando apenas em critérios éticos? Os problemas no Oriente Médio, o desrespeito às resoluções da ONU por parte de alguns Estados, tudo isso mostra a pouca eficácia do discurso quando não acompanhada da força. O objetivo deste trabalho é apontar os limites da ética pura para combater a violência e mostrar que a normatização do mundo não pode, ainda, prescindir da “crítica das armas”.

    2009-04-01

    The paper has intercompared and verified Regional Climate Model (RCM) EBU-POM in its representation of the hydrological balance over the Danube river basin along Iron Gate gorge, for the time frame 1961-1990 and 2071-2100 according to the IPCC SRES scenario A1B. The Danube has been chosen as a case study because of its multiple relevance for socioeconomical, as well as environmental and climatic level. This part of the Danube river basin has a direct relevance to the Mediterranean region, since it provides a relevant input of freshwater to the sea, as well as being fuelled mostly by precipitations due to the water of Mediterranean origin. On the other, the Dinaric-Balkan mountain chains in the west and the Carpathian mountain bow in the north and east, present distinctive morphological and climatic regions and barriers. Having been aware of the climatic-hydrologic and hydrographic homogeneity of regions, the whole territory of Serbia is divided into 20 units basins. The part of Danube basin in its eastern part present one of them, and was subject of the research. For this balance unit, the main components of the balance equation of the water that included into the calculation are: precipitation P (mm), flow Q (m3/s), runoff depth h (mm), evaporation E (mm) and annual air temperature T (0C). The hydrological balance has been computed in two different, but in principle equivalent ways. The first approach, which has a more hydrological nuance, relies on establishing relationships between annual averages of the hydrological balance parameters (E, P, T) in order to get relevant coefficients. The second approach, which is more typically meteorological, relies on the calculation of the E for the time frame 2071-2100 by using the previous coefficients. On the basis of the assessment of climate parameters in the XXI century and with help of the established relationships, the water flow of Danube river and runoff depth were defined for this century. The outcomes are very

    Full Text Available Whilst many studies show sex differences in cerebral asymmetry, their mechanisms are still unknown. This report describes the potential impact of sex hormones and sex chromosomes by comparing MR data from 39 male and 47 female controls and 33 men with an extra X-chromosome (47,XXY Methods: Regional asymmetry in grey and white matter volumes (GMV and WMV was calculated using voxel based moprhometry (SPM5, by contrasting the unflipped and flipped individual GMV and WMV images. In addition, structural volumes were calculated for the thalamus, caudate, putamen, amygdala, and hippocampus, using the FreeSurfer software. Effects of plasma testosterone and estrogen on the GMV and WMV, as well on the right/left ratios of the subcortical volumes were tested by multi-regression analysis.Results: All three groups showed a leftward asymmetry in the motor cortex and the planum temporale, and a rightward asymmetry of the middle occipital cortex. Both asymmetries were more pronounced in 46,XY males than 46,XX females and 47,XXY males, and were positively correlated with testosterone levels. There was also a rightward asymmetry of the vermis and leftward asymmetry in the cerebellar hemispheres in all groups. Notably, cerebellar asymmetries were larger in 46,XX females and 47,XXY males, but were not related to sex hormone levels. No asymmetry differences between 46,XX females and 47,XXY males, and no overall effects of brain size were detected.Conclusion: The asymmetry in the planum temporale area and the occipital cortex seem related to processes associated with testosterone, whereas the observed cerebellar asymmetries suggest a link with X-chromosome escapee genes. Sex differences in cerebral asymmetry are moderated by sex hormones and X-chromosome genes, in a regionally differentiated manner.

  17. DebrisInterMixing-2.3: a finite volume solver for three-dimensional debris-flow simulations with two calibration parameters - Part 1: Model description

    Here, we present a three-dimensional fluid dynamic solver that simulates debris flows as a mixture of two fluids (a Coulomb viscoplastic model of the gravel mixed with a Herschel-Bulkley representation of the fine material suspension) in combination with an additional unmixed phase representing the air and the free surface. We link all rheological parameters to the material composition, i.e., to water content, clay content, and mineral composition, content of sand and gravel, and the gravel's friction angle; the user must specify only two free model parameters. The volume-of-fluid (VoF) approach is used to combine the mixed phase and the air phase into a single cell-averaged Navier-Stokes equation for incompressible flow, based on code adapted from standard solvers of the open-source CFD software OpenFOAM. This effectively single-phase mixture VoF method saves computational costs compared to the more sophisticated drag-force-based multiphase models. Thus, complex three-dimensional flow structures can be simulated while accounting for the pressure- and shear-rate-dependent rheology.

    Building on a technical result by Brunnemann and Rideout on the spectrum of the Volume operator in Loop Quantum Gravity, we show that the dimension of the space of the quadrivalent states --with finite-volume individual nodes-- describing a region with total volume smaller than $V$, has \\emph{finite} dimension, bounded by $V \\log V$. This allows us to introduce the notion of "volume entropy": the von Neumann entropy associated to the measurement of volume.

    2016-12-06

    Here I briefly delineate my view about the main question of this International Seminar, namely, what should we expecting from the XXI Century regarding the advancements in intelligence research. This view can be summarized as 'The Brain Connection' (TBC), meaning that neuroscience will be of paramount relevance for increasing our current knowledge related to the key question: why are some people smarter than others? We need answers to the issue of what happens in our brains when the genotype and the environment are integrated. The scientific community has devoted great research efforts, ranging from observable behavior to hidden genetics, but we are still far from having a clear general picture of what it means to be more or less intelligent. After the discussion held with the panel of experts participating in the seminar, it is concluded that advancements will be more solid and safe increasing the collaboration of scientists with shared research interests worldwide. Paralleling current sophisticated analyses of how the brain computes, nowadays science may embrace a network approach.

Todo el quehacer museal se orienta a satisfacer los gustos y necesidades del sujeto visitante para así atraerlo al Museo. Este nuevo enfoque museológico tiene el riesgo de olvidar el objeto en el proceso educativo y centrarse en el sujeto. Se propone la promoción del diálogo sujeto-objeto para que la función educativa del Museo contribuya a la conformación de una sociedad con conciencia histórica-cultural clara. Se concluye que, en las primeras décadas del Siglo XXI los diferentes enfoques de la sociomuselogía, la museografía interactiva, la museología crítica y dialógica, así como los ejes de cambio generados por las innovaciones tecnológicas, las dinámicas de consumo y las comunidades de aprendizaje, apuntan a que la audiencia es el centro de atención, y no el objeto y la forma de ser expuesto como lo fue en el Siglo XX.

    Aim To review systematically the neurodevelopmental characteristics of individuals with sex chromosome trisomies (SCTs). Method A bibliographic search identified English-language articles on SCTs. The focus was on studies unbiased by clinical referral, with power of at least 0.69 to detect an effect size of 1.0. Results We identified 35 articles on five neonatally identified samples that had adequate power for our review. An additional 11 studies were included where cases had been identified for reasons other than neurodevelopmental concerns. Individuals with an additional X chromosome had mean IQs that were within broadly normal limits but lower than the respective comparison groups, with verbal IQ most affected. Cognitive outcomes were poorest for females with XXX. Males with XYY had normal-range IQs, but all three SCT groups (XXX, XXY, and XYY) had marked difficulties in speech and language, motor skills, and educational achievement. Nevertheless, most adults with SCTs lived independently. Less evidence was available for brain structure and for attention, social, and psychiatric outcomes. Within each group there was much variation. Interpretation Individuals with SCTs are at risk of cognitive and behavioural difficulties. However, the evidence base is slender, and further research is needed to ascertain the nature, severity, and causes of these difficulties in unselected samples. PMID:20059514

    2011-01-01

    Full Text Available Este trabajo analiza tres textos creativos de distintos géneros que recrean en el siglo xxi la imagen de Manuela Sáenz, la famosa amante del Libertador suramericano Simón Bolívar. Se arguye que en la ópera, la novela y la película examinadas se invita al lector/espectador a repensar el papel que jugó la heroína quiteña en la política grancolombiana de su época. Este trabajo discute cómo el esfuerzo por actualizar la imagen de Manuela Sáenz implica negociar la creación de una nueva imagen que surge de la mezcla de la idea fosilizada en el imaginario colectivo latinoamericano de la quiteña como una sacrificada amante, y una versión más contemporánea de Manuela como un agente político que tuvo una injerencia determinante en los asuntos de estado durante los años de la Gran Colombia.

    Full Text Available The paper discusses an approach to a long-term forecast of river runoff changes for Russian large river basins in the first third of the XXI century caused by climate warming and social-economic changes. The approach considers runoff changes under a range of possible climate warming effects. This range is chosen by generalizing the calculation results obtained by using an ensemble of global climate models within CMIP 3 and CMIP 5 experiments for twocontrasting scenarios (A2/RCP 8.5 and B1/RCP 2.6 of globally averaged air temperature rises. The approach also utilizes a method for alternative scenario for water consumption related to socio-economic changes. The obtained scenario estimates show that expected changes in the Volga and Don annual river runoff and its intra-annual distribution in the first third of this century can be relatively small, while changes in water use characteristics may be extremely negative in some scenarios, especially in the Don River basin.

    Full Text Available En esta entrevista, el profesor Edgar Morin introduce sus nuevos debates, reflexiones y preocupaciones sobre lo que significa formar en la universidad del siglo xxi. Hay una honda preocupación por dar fin al modelo universitario del siglo xix, que favorece a la fragmentación del conocimiento, los saberes y las disciplinas, desde estructuras académico-administrativas que niegan la integración, la complejidad y la interdisciplinariedad del conocimiento contemporáneo. Morin insiste en que la universidad de hoy deberá centrase en la formación de un "ciudadano planetario", concentrado en pensar e interactuar con los nuevos problemas y epistemologías que plantea la sociedad actual. También insiste en que la universidad deberá formar para la vida, el sentido, la pasión y la transformación del mundo. Eso implica formar en tres dimensiones analíticas y transversales: a los nuevos problemas universales/locales; b las nuevas epistemologías que produce y entrega la sociedad contemporánea; y c los "saberes civilizatorios" que constituyen las sociedades modernas, planetarias, integradas y complejas.

    A number of patients with both sex chromosome aneuploidy and the fragile X syndrome have been reported and this has led to the hypothesis that females heterozygous for the fragile X mutation have an increased rate of meiotic nondisjunction. Furthermore the suggestion has frequently been made that a predisposition to meiotic nondisjunction is associated with an increase in mitotic nondisjunction. We have tested these two hypotheses by examining the chromosomes of a series of 47,XXY males and their parents. In the majority the parental origin of the additional sex chromosome was known. The cells were cultured under conditions suitable for demonstrating the fragile X and 100 cells were scored 'blind' from the patients and both parents. No fragile X individual was seen and there was no difference in the proportion of aneuploid cells between the parents in whom the nondisjunction event occurred and the control parents. Therefore, our results lend no support to the suggestions that the fragile X is associated with an increase in sex chromosome aneuploidy or that individuals in whom meiotic nondisjunction occurs have an increased level of mitotic nondisjunction.

    Documentation of the preliminary software developed as a framework for a generalized integrated robotic system simulation is presented. The program structure is composed of three major functions controlled by a program executive. The three major functions are: system definition, analysis tools, and post processing. The system definition function handles user input of system parameters and definition of the manipulator configuration. The analysis tools function handles the computational requirements of the program. The post processing function allows for more detailed study of the results of analysis tool function executions. Also documented is the manipulator joint model software to be used as the basis of the manipulator simulation which will be part of the analysis tools capability.

    The purpose of the study was to determine the distribution and abundance of cetaceans in areas potentially affected by future oil and gas activities along the continental slope of the north-central and western Gulf of Mexico. This 3.75 year project commenced 1 October 1991 and finished 15 July 1995. The study area was bounded by the Florida-Alabama border, the Texas-Mexico border, and the 100 m and 2,000 m isobaths. Cetacean distribution and abundance were determined from seasonal aerial and shipboard visual surveys and shipboard acoustic surveys. In addition, hydrographic data were collected in situ and by satellite remote sensing to characterize cetacean habitat. Finally, tagging and tracking of sperm whales using satellite telemetry was attempted. Appendix C Part 2 contains the hydrogrpahic data collected during TIO Cruises 5-7. Cetaceans were observed throughout the study area during all four seasons. Nineteen species were identified, including two species (melon-headed whales and Fraser`s dolphins) previously thought to be rare in the Gulf. Pantropical spotted dolphins, bottlenose dolphins, clymene dolphins, striped dolphins, Atlantic spotted dolphins, and melon-headed whales were the most common small cetaceans and the sperm whale was the most common large cetacean. The mean annual abundance for all cetaceans was estimated to be 19,198. Although the study area had complex and dynamic oceanography, bottom depth was the only environmental variable which correlated to cetacean distribution.

    Full Text Available A política sul-americana transformou-se na primeira década do século XXI. Presenciamos um conjunto de processos insurrecionais que fizeram das novas formas de movimentos sociais os protagonistas das lutas na região. Na Bolívia, no Equador e na Venezuela o recrudescimento da luta de classes propiciou a ascensão de governos que expressaram esse novo momento. Evo Morales, Rafael Corrêa e Hugo Chávez simbolizaram a emergência de um novo momento político na América do Sul. Diferentemente de períodos anteriores de luta, nessa nova fase, presenciamos o abandono da luta armada, por meio da utilização da via institucional. Presenciamos, também, a realização das Assembleias Constituintes e o fomento à democracia participativa como instrumentos para as mudanças sociopolíticas. Além disso, assistimos à reivindicação de um novo tipo de socialismo, o Socialismo do Século XXI. Essa proposta começou a ser difundida na Venezuela entre os anos de 2004 e de 2006, com a radicalização da revolução bolivariana. A consolidação do chavismo e o êxito das outras insurreições populares sul-americanas também possibilitaram essa difusão. Realizamos neste artigo uma comparação da construção do Socialismo do Século XXI na Bolívia, Equador e Venezuela, por meio dos discursos políticos e programas de governos ocorridos nesses três processos políticos

    In hospitalized and chronically ill children, the prevalence of psychopathology is very high. It is necessary that in its prevention, diagnosis and treatment not only professionals of the mental health disciplines intervene but also that the pediatricians, nurses and the family of the patient himself participate actively. Consultation Liaison Child Psychiatry activities at the Pediatric Hospital of the National Medical Center "Siglo XXI" are described. Its goal is to incorporate the mental health professional to the team of hospital care and promote that pediatricians gain a greater conscience of psychological and social factors that are crucial for the sick child.

    1994-10-01

    This volume, the second of two such volumes, contains sector-specific guidance in support of the General Guidelines for the voluntary reporting of greenhouse gas emissions and carbon sequestration. This voluntary reporting program was authorized by Congress in Section 1605(b) of the Energy Policy Act of 1992. The General Guidelines, bound separately from this volume, provide the overall rationale for the program, discuss in general how to analyze emissions and emission reduction/carbon sequestration projects, and address programmatic issues such as minimum reporting requirements, time parameters, international projects, confidentiality, and certification. Together, the General Guidelines and the guidance in these supporting documents will provide concepts and approaches needed to prepare the reporting forms. This second volume of sector-specific guidance covers the transportation sector, the forestry sector, and the agricultural sector.

    Full Text Available Studying genetically defined syndromes associated with increased risk for psychopathology may help in understanding neurodevelopmental mechanisms related to risk for psychopathology. Klinefelter syndrome (47,XXY is one of the most common sex chromosomal aneuploidies (1 in 650 male births and associated with increased vulnerability for psychopathology, including psychotic symptoms. Yet, it remains unknown whether this increased risk is associated with underlying psychophysiological mechanisms that are typically deficient in individuals with psychotic disorders. The present study assessed three "classic" psychophysiological markers of psychosis in Klinefelter syndrome (KS: smooth pursuit eye movements (SPEM, prepulse inhibition (PPI and P50 suppression. Fourteen adults with KS and 15 non-clinical adults participated in the study. Data on SPEM (reflecting visuo-motor control as well as PPI and P50 suppression (reflecting sensory gating were collected. Dysfunctions in SPEM were observed in individuals with KS, with less smooth pursuit as expressed in lower position gain. Also, reduced sensory gating in individuals with KS was suggested by significantly reduced prepulse inhibition of the startle response (PPI (effect size 1.6. No abnormalities were found in suppression of the P50 (effect size 0.6. We speculate that impairments in these psychophysiological mechanisms may reflect core brain dysfunctions that may also mediate the described increased vulnerability for psychotic symptoms in KS. Although speculative, such deficit specific, rather than disorder specific, psychophysiological dysfunctions in KS might convey vulnerability to other types of psychopathology as well. As KS already can be diagnosed prenatally, the predictive value of childhood impairments in prepulse inhibition and smooth pursuit for development of psychopathology later in life could be assessed. In sum, studying individuals with KS may prove to be an avenue of research leading to

    Full Text Available Purpose of the article is to analyze the philosophical and cultural ideas about television, which is a leading visual practice of XX century. It does not lose its relevance in the beginning of the XXI. The role of television lies in visual presentation and formation of the basic norms of taste and traditions of different social groups. Television is the leading communicative practice, which consideration is represented differently in modern science. Research methodology involves an appeal to the philosophical and cultural concepts, representing different approaches to the understanding of television. The paper considers the views of Western scholars, such as R. Arnheim, M. Wolff, A. Kroker, G. Lipovetsky, M. McLuhan, D. Mulvin, J. Mittell, N. Postman, L. Saffhil, J. Sterne, E. Thompson, J. Fiske, S. Shapiro. During analysis of the issue of the specific nature of television content the works of Russian scientists – T. Savitskaya, N. Samutina and Polish contemporary author – R. Sapenko were used. Originality lies in the depiction of the main approaches to the study of television as a visual communicative practice. Deployment of the author's position within the designated issues is presented as a historical digression – from the first attempts at understanding the phenomenon of television to the newest scientific theories that have found expression in contemporary American philosophical and cultural thought. Results of the study can be used in the training course "Visual communication and practices." Conclusions indicated that the majority of contemporary visual practices based on certain patterns, embedded TV. Despite the emergence of new media practices, TV does not lose relevance, everywhere present in the culture, which means that his research will allow a better understanding of the specificity of cultural creativity process.

    Full Text Available The theory of law, after the first decade of this century, needs to approach the new features assimilated by legal dogmatics whether to remain a space of observation and constructive thinking. The dogmatic is still linked to the language paradigm that forces the lawyers to review their semantics. For both, there is the realization of Humberto Maturana and Niklas Luhmann’s epistemological projections in law to build social networks focused on society as autopoietic. This paper attempts to show the different perspectives on the theory of autopoietic social systems and their relationship with the production of meaning and paradox, the search for a concept that can be operatonalized by law.Resumo: A teoria do Direito, passada a primeira década do século XXI, precisa se aproximar das novas feições assimiladas pela dogmática jurídica se pretende continuar a ser um espaço de observação e de reflexão construtiva.

Para tanto, observa-se a realização das projeções epistemológicas de Humberto Maturana Romesín e de Niklas Luhmann, noDireito, para a construção de redes sociais voltadas à sociedade como autopoiese. Nessa linha de ideias, este ensaio pretende abordar as diferentes perspectivas existentes sobre a Teoria dos SistemasSociais Autopoiéticos e sua relação com a produção do sentido, e o paradoxo à procura de um conceito que possa ser operacionalizado peloDireito.

Sus conclusiones se condensaron en un documento denominado “Retos del montañismo en el siglo xxi”, dirigido fundamentalmente a las organizaciones de montañismo. En España, una sola federación, la Federación Española de Deportes de Montaña y Escalada, sostenida por las federaciones autonómicas integradas en ella, aglutina diferentes modalidades deportivas. Sin embargo, las organizaciones de montañismo, reglamentadas y gestionadas desde la administración deportiva, se verán obligadas a tender puentes de comunicación con administraciones turísticas, medioambientales, de interior, educativas, etc., para dar cumplimiento a los retos del siglo xxi. Además, empresas y organizaciones de muy diverso signo, coinciden en el mismo terreno de juego: el medio natural. Para dar respuesta a esos “retos”, las federaciones y clubes deportivos parten de la legislación que existe en estos momentos. En el artículo se expone la panorámica legislativa actual y se reflexiona sobre las fortalezas, debilidades y conexiones que les permitirán cumplir con los “Retos del montañismo en el siglo XXI”.

  13. Climate Change of Franz Josef Land in the XX-XXI Centuries

    The results of climatic observations on the most northern land of Eurasia - Franz Josef Land, that was discovered in 1874, are presented. The gaps in the observations of the observatory named after Ernst Krenkel (Hayes's Island) were supplemented by calculations using reanalysis ERA Interim. It was received the positive trend in surface air temperature during 1958-2013. It is mainly achieved by increasing of the air temperature in winter but the summer trend is not statistically significant. Data of observation and reanalysis are perfectly correlated in cold period when underlying surface is uniform (correlation coefficient of more than 0.95). In summer, the correlation coefficients between the calculated and the real data are significantly lower (up to 0.68). This fact may be a consequence of the small values of the mean air temperatures of summer months (for example, during the July they varied in the interval -1-+2 degrees C.). Furthermore, it may be caused by the difficulty of model reproduction of the real state of the underlying surface, where land, ice, snow and water are chaotically combined. The analysis of circulation types by B.L. Dzerdzeevsky has shown that in the mid-XX Century, the northern meridional and western zonal types of circulation were replaced by southern meridional one, which prevailed during the first decade of the XXI too. This causes a reduction of the ice cover period, which resulted in a strengthening of the beach erosion and of slope processes. But short-term flows of warm air from the south, causing a catastrophic melting of glaciers, were also repeatedly marked in the past.

    In view of growing public attention to modern ecological and climatic problems, one of the most important problems of meteorology and climatology is to develop realistic scenarios of future climatic changes. The modern general circulation (GCM) and regional atmospheric (RM) models allow to reproduce meteorological fields with the spatial grid resolution about 50×50 and 5x5 km, respectively. Such model resolution is, unfortunately, not allow to enough adequately describing the climatic condition of the cities. Taking into account big differences of meteorological conditions in- and outside of the cities the prediction uncertainties provided by GCM and RM models for cities may be relatively large. Within the framework of this study the simple model allowing to reproduce climatic conditions of the city was developed. It was applied to predict temperature regime in Moscow region in Russia for the middle and the end of XXI century. It based on the data provided by GCM and RM models and allows to predict meteorological condition with spatial resolution about 0,5 km×0,5 km. In the study it was shown that the thermal regime of Moscow area as well as Moscow surrounding areas are well reproduced by developed model. The model allows to describe realistically a spatial heterogeneity of temperature in July both under modern and future climatic conditions. It was also shown, that the area of "warm islands" in Moscow is characterized by very high probability of extreme event occurrency. In July 2050 the probability of this occurrency of will be significantly higher than at present The same thing we can say about the climate of 2100. Thus, in the near future the climate of Moscow during the summer period will be hotter, and it will result in different environmental problems and increased energy demand.

De este modo se verá que los dioses, sus aspectos y funciones, han recibido un tratamiento prioritario al ser el objeto principal de las fuentes, dejándose de lado a los ancianos reales y los temas prosaicos. Las más desfavorecidas han sido las mujeres, de las que sólo se destaca su labor como parteras, curanderas, etc. y su faceta sobrenatural. Finalmente, el conocimiento que se tiene de unos y de otras se desprende de la comparación con sus homólogas divinas.In the following text I will explain the studies done in relation to eldery mesoamerican people, particularly prehispanic Mayan women, all through the 20th century to the beginning of the 21st century in the fields of History, Archaeology, Anthropology, Epigraphy, and Iconography, seen from the point of view of age and gender, and parting from the general to specifics. In this manner, we will see that the gods, their appearance, and their functions have received privileged treatment in these sources, leaving aside the real elders, and prosaic topics. Women have received the least favourable treatment, being only their work as midwives and healers, and their link to the supernatural what has been noticed. Finally, the knowlege that we have about women and men is the result of the comparison with their gods.

La ciencia ficción, en el cine y la literatura, siempre ha sido el género de la anticipación, de la predicción, y no se ha estructurado sólo desde la imaginación, pues sus relaciones con la ciencia son estrechas, a tal punto que ha hecho que se desdibujen muchas veces sus límites. La ciencia ficción es el folclor del hombre contemporáneo y entenderla es entender un poco lo que los hombres piensan de sí mismos y de su futuro.

    Full Text Available Ovotesticular disorder of sex development (OT-DSD is a rare disorder of sexual differentiation characterized by the presence of both ovarian and testicular tissues in the same individual. It's incidence ranges from 3% to 10% of all disorder of DSD's, and the most common presentation is 46, XX followed by 46, XX/46, XY mosaicism and 46, XY. Klinefelter syndrome (KS mosaicism 46, XX/47, XXY is extremely rare, and its association with the ovotesticular disorder is even rarer. We report an unusual case of 16-year-old with male habitus who presented with complains of cyclic hematuria. On examination, he had bilateral gynecomastia, unilateral left cryptorchidism, absent facial hair, sparse axillary hair growth, and pubic hair distribution of feminine type. The right testis was of normal size located normally in hemiscrotum and was confirmed by radio imaging. Ultrasonography and magnetic resonance imaging revealed a cystic area behind posterior half of urinary bladder. Chromosomal analysis revealed 46, XX/47, XXY mosaicism of female karyotype and KS. Histopathological report of this left side excised specimen confirmed the structures to be ovary, uterus, and fallopian tube, thus confirming our diagnosis of the lateral ovotesticular disorder. Meticulous workup combined interdisciplinary approach will lead to early diagnosis and resolve timely sex reassignment issues and also prevent consequences arising due to gonadal insufficiency.

    Full Text Available Individuals with an extra X chromosome (Klinefelter syndrome are at risk for problems in social functioning and have an increased vulnerability for autism traits. In the search for underlying mechanisms driving this increased risk, this study focused on social attention, affective arousal and empathy. Seventeen adults with XXY and 20 non-clinical controls participated in this study. Eyetracking was used to investigate social attention, as expressed in visual scanning patterns in response to the viewing of empathy evoking video clips. Skin conductance levels, reflecting affective arousal, were recorded continuously during the clips as well. Empathic skills, i.e. participants' understanding of own and others' emotions in response to the clips was also assessed. Results showed reduced empathic understanding, decreased visual fixation to the eye region, but increased affective arousal in individuals with Klinefelter syndrome. We conclude that individuals with XXY tend to avoid the eye region. Considering the increased affective arousal, we speculate that this attentional deployment strategy may not be sufficient to successfully downregulate affective hyper-responsivity. As increased affective arousal was related to reduced empathic ability, we hypothesize that own affective responses to social cues play an important role in difficulties in understanding the feelings and intentions of others. This knowledge may help in the identification of risk factors for psychopathology and targets for treatment.

    Full Text Available Direct forms of confrontation represent one of the main features of the social conflict in Argentina in the xxI century. Particularly, the hostile outbursts have constituted a dynamic that is present throughout the decade. The public system of railway transportation of passengers in the metropolitan area of Buenos Aires was one of the social spaces with the most recurrence of this kind of collective action. Between 2003 and 2009 a cycle of hostile outbursts took place, in which groups of passengers attacked goods and employees of the concessionary enterprise –and in some cases security forces involved– showing its social dissatisfaction with the quality of service. In this paper, we expose a hypothetical frame in order to explain these events while promoting a conceptual debate about this kind of action.Las formas directas de confrontación representan una de las características salientes de la conflictividad social en la Argentina del siglo XXI. En particular, los estallidos de hostilidad constituyen una dinámica presente a lo largo de toda la década. El transporte ferroviario de pasajeros del área metropolitana de Buenos Aires se erigió en uno de los espacios sociales con gran recurrencia de este tipo de acciones. Entre 2003 y 2009 se desarrollaron una serie de estallidos en los cuales grupos de pasajeros atacaban bienes y trabajadores de las empresas prestatarias –y en ocasiones a las fuerzas de seguridad que intervenían– con el objeto de expresar su disconformidad con la forma de prestación del servicio. En este artículo exponemos los resultados de nuestra investigación sobre dichos episodios, presentando un marco hipotético-conceptual que da cuenta de los mismos y promueve en simultáneo un debate conceptual sobre esta forma de acción directa.

    Full Text Available Based on Foucault’s concept of the body as the surface of inscription of history, and on the work of Judith Butler, this article questions the way that binary and normative conceptions of gender operate in the constitution of a field of intelligibility for subjects and their bodies. We analyse the film XXY (2007 that tells the story of Alex, an intersexual adolescent. We use the main character's story to see how gender norms act to shape bodies and limit their pleasures. We argue that subjects and bodies that do not correspond to the normative ideal are seen as “abject bodies”, following Butler’s definition. The argument is that gender norms operate on all bodies: the normal and the abject.

    Full Text Available In XX and XXI centuries in connection with the radical social changes researchers have at-tempted to analyze the current transformation and to show their influence on the political, economic, social and cultural development of the country. The most important institutions of culture, i.e. theater, has passed a long way of reforming. The goals and objectives have always reflected the needs of society, the level of cultural development, profound moral needs of different social groups, as well as state policy concerning culture. Modernization of Russian theater took place in difficult historical conditions. Historical retrospective allows us to consider the development of theatrical business in Russia at the turn of XX – XXI centuries, to identify the positive aspects and shortcomings in the work of theaters in the new reality, to identify trends in the further development. Of particular importance for the study of Russian theater period of radical change is the study of theatrical business in the south of the Far East. The border location of the region, the special composition of the population, remoteness from the center of the country determined its specific development. At present, despite the attention of the Russian government paid at the development of the Far East, the region remains being the area with the lack of the necessary infrastructure. The problem of human resources and staff turnover is much sharper than in the central regions of the Russian Federation. Therefore, the study and compilation of the historical experience gained by researchers of the Far East, is important.

    To gain a better understanding of the risk significance of low power and shutdown modes of operation, the Office of Nuclear Regulatory Research at the NRC established programs to investigate the likelihood and severity of postulated accidents that could occur during low power and shutdown (LP&S) modes of operation at commercial nuclear power plants. To investigate the likelihood of severe core damage accidents during off power conditions, probabilistic risk assessments (PRAs) were performed for two nuclear plants: Unit 1 of the Grand Gulf Nuclear Station, which is a BWR-6 Mark III boiling water reactor (BWR), and Unit 1 of the Surry Power Station, which is a three-loop, subatmospheric, pressurized water reactor (PWR). The analysis of the BWR was conducted at Sandia National Laboratories while the analysis of the PWR was performed at Brookhaven National Laboratory. This multi-volume report presents and discusses the results of the BWR analysis. The subject of this part presents the deterministic code calculations, performed with the MELCOR code, that were used to support the development and quantification of the PRA models. The background for the work documented in this report is summarized, including how deterministic codes are used in PRAS, why the MELCOR code is used, what the capabilities and features of MELCOR are, and how the code has been used by others in the past. Brief descriptions of the Grand Gulf plant and its configuration during LP&S operation and of the MELCOR input model developed for the Grand Gulf plant in its LP&S configuration are given.

Los hallazgos plantean que la información del comunicador social no puede estar alejada de los cambios que la tecnología de la información y la comunicación impone en este siglo XXI. Tampoco se debe sobredimensionar sus características y potencialidades, pero sí reconocer los impactos que tiene sobre la profesión y la manera cómo se ha introducido aceleradamente dentro de este campo, en este sentido, muchas de las escuelas de comunicación social no han planificado la introducción de las tecnologías de la comunicación y la información en sus pensum de estudio y, por lo tanto, no hay una combinación de saberes fundamentales y aplicados y diferenciados en el proceso instruccional y en el modelo curricular, que le da organicidad de criterios y responda a las exigencias del mercado laboral, a las expectativas de los estudiantes, de los egresados y a la función misma de la universidad orientada al desarrollo completo de los individuos en sus relaciones con la sociedad, el mundo y la vida.

    We develop a universal distributional calculus for regulated volumes of metrics that are suitably singular along hypersurfaces. When the hypersurface is a conformal infinity we give simple integrated distribution expressions for the divergences and anomaly of the regulated volume functional valid for any choice of regulator. For closed hypersurfaces or conformally compact geometries, methods from a previously developed boundary calculus for conformally compact manifolds can be applied to give explicit holographic formulæ for the divergences and anomaly expressed as hypersurface integrals over local quantities (the method also extends to non-closed hypersurfaces). The resulting anomaly does not depend on any particular choice of regulator, while the regulator dependence of the divergences is precisely captured by these formulæ. Conformal hypersurface invariants can be studied by demanding that the singular metric obey, smoothly and formally to a suitable order, a Yamabe type problem with boundary data along the conformal infinity. We prove that the volume anomaly for these singular Yamabe solutions is a conformally invariant integral of a local Q-curvature that generalizes the Branson Q-curvature by including data of the embedding. In each dimension this canonically defines a higher dimensional generalization of the Willmore energy/rigid string action. Recently, Graham proved that the first variation of the volume anomaly recovers the density obstructing smooth solutions to this singular Yamabe problem; we give a new proof of this result employing our boundary calculus. Physical applications of our results include studies of quantum corrections to entanglement entropies.

Destaca-se que os últimos dez anos foram marcados por modificações nas políticas sociais, porém estas mudanças seguem o caminho da continuidade do período anterior. Isto fez com que essas permanecessem subordinadas às políticas macroeconômicas do país, as quais atuam em perfeita sintonia com a lógica do grande capital. Neste cenário, as políticas sociais atuam apenas para conter os malefícios do capital, não tendo papel mais efetivo no sentido de impor limites a esta lógica perversa. Por isso, concluiu-se que a ampla coesão social que dá suporte ao Governo Lula acaba sendo também um fator limitante das ações das políticas sociais na luta pela efetiva democratização do país. This article analyze the social policy during the first decade of XXI Century, period of time that we can see some progress, but at the same time we see also huge limits to built a global social protection system. The last ten years were marking by changes in the social policies, but these alterations following the way of continuity of the last period. This option let the social policy subordinated to the macroeconomics policies, which one are following the logic of the international capital. In this scenario, the function of social policies is to hold the bad situation promoted by the capitalism system. In this sense, the article concludes that the social coalition that is supporting the Lula‟s Government has been worked like a limit to the social policy in its function to build a democratic system in the country.

    Full Text Available Este artículo surge de la necesidad de discutir los diversos impactos generados por el proceso de globalización en la medida que interfiere en las relaciones políticas, económicas, sociales, culturales, que se expresan en degradación ambiental y constituyen fuertes amenazas para la salud de individuos y comunidades a nivel local y global. Se propone estimular la reflexión a partir del análisis interdisciplinar del conocimiento producido sobre macro categorías como globalización, medio ambiente y salud y su articulación con el ejercicio profesional del enfermero. Metodológicamente se trata de una sistematización a partir de fuentes bibliográficas primarias y secundarias disponibles inclusive en bases indexadas. Podemos concluir que el ejercicio profesional de enfermería en el siglo XXI exige enfrentar el desafío de (redimensionar el cuidado, que debe ser entendido no como un acto y si como una actitud cuidadora y un compromiso con la defensa de la vida de ésta y las futuras generaciones.This article is a result of the necessity of discussing the many impacts that the globalization process, since it affects way the political, economical and social relations, that are expressed in the environmental degradation and becomes a strong threat to the health of individuals and communities in the local and global levels. Intends to stimulate a reflection from the interdisciplinary analysis of the developed knowledge about categories like globalization, environment and health, and their articulation with the professional nursing practice. In a methodological point of view, it is systematization from primary and secondary bibliographic sources including indexed ones. We conclude that the professional nursing practice in the XXI century demands confronting the challenge of resize the concept of nursing care, must be understood not as an act but as a caring actitude and a commitment to the protection of life of this and future's generations.

    Full Text Available RESUMO Introdução O Relatório Flexner é considerado o ponto de partida para a discussão do ensino da medicina no século XX. Após amplas discussões, em 2001, o Ministério da Educação homologa as Diretrizes Curriculares Nacionais do Curso de Graduação em Medicina (DCN. Tais diretrizes objetivam a formação de um médico generalista, humanista, reflexivo, crítico, que atue como promotor da saúde integral do ser humano. A Pediatria é a área da medicina onde a promoção da saúde integral é de extrema importância, pois a criança é o adulto do futuro. Objetivo Discutir as questões: O que se espera do médico geral, em relação à Pediatria, no século XXI? E a questão dela derivada: Mudanças nas diretrizes para o ensino de Pediatria são necessárias a partir das DCN? Métodos Ensaio reflexivo com base em dois documentos: Diretrizes Curriculares Nacionais do Curso de Graduação em Medicina (DCN e Diretrizes para o Ensino de Pediatria (DEP propostas por Eduardo Marcondes. Discussão Este artigo discorre a respeito das percepções de Marcondes acerca do ensino de Pediatria, correlacionando-as com as DCN e discutindo aspectos importantes na formação do médico, tais como: promoção, prevenção, proteção e reabilitação em saúde e educação médica em Pediatria. Considerações finais As Diretrizes para o Ensino de Pediatria propostas por Marcondes em 1993 parecem se manter extremamente atuais no contexto brasileiro do século XXI, ressalvando-se apenas diferenças de mortalidade e morbidade infantil.

El panorama de la última década se reconstruyó con base en análisis de aerofotografías, cuantificación de datos censales y análisis de datos de las entidades de planificación y control a la urbanización informal. Los resultados sugieren que debido al agotamiento relativo del suelo en Bogotá, entre otros aspectos, las dinámicas a partir de las cuales opera el mercado informal han experimentado cambios frente a décadas anteriores, pues el crecimiento en densificación de asentamientos en la ciudad consolidada cobra mayor importancia relativa frente al desarrollo informal en las periferias, pero a la vez se intuye una expansión de la informalidad que trasciende el perímetro distrital.

    Full Text Available Abstract Background The association of achondroplasia and Klinefelter syndrome is extremely rare. To date, five cases have been previously reported, all of them diagnosed beyond the postnatal period, and only one was molecularly characterized. We describe the first case of this unusual association diagnosed in the neonatal period, the clinical findings and the molecular studies undertaken. Case presentation The boy was born at term with clinical and radiological features indicating the diagnosis of achondroplasia or hypochondroplasia combined with the prenatal karyotype of Klinefelter syndrome (47,XXY. Neonatal FGFR3 mutation screening showed that the newborn was heterozygous for the classic achondroplasia G340R mutation. Microsatellite marker analysis showed that the sex chromosome aneuploidy had arisen from a non-disjunction error in paternal meiosis I, with a recombination event in the pseudoautosomal region 1 (PAR1. Conclusion Specific mutation analysis is appropriate to confirm the clinical diagnosis of achondroplasia for appropriate diagnosis, prognosis, and genetic counseling, especially when the karyotype does not explain the abnormal prenatal sonographic findings. In the present case, a recombination event was observed in the PAR1 region, although recombinational events in paternally derived Klinefelter syndrome cases are much rarer than expected.

    Full Text Available The article describes the process and results of the geopolitical and geoeconomic changes in the Baltic Sea region at the turn of the XX and XXI centuries. The authors assess the political, economic and military potential of individual countries and groups of countries. Ranking the selected countries and grouping them according to the similarity of their characteristics requires a variety of methods — the economic, statistical, cartographic, graphic-analytical methods, to name just a few. In the late 1980s — early 1990s, there were three socialist countries in the Baltic Sea region. They were signatories of the Warsaw Pact and members of the Council for Mutual Economic Assistance (the Soviet Union, Poland and East Germany. The Baltic Sea region housed four market economies (Sweden, Finland, Denmark and Germany. Only two of them were members of NATO and the EU (Germany and Denmark. At present, there are eight EU countries in the region; six of them are NATO members (Germany, Sweden, Denmark, Poland, Lithuania, Latvia and Estonia, and the same two countries, Sweden and Finland, remain outside the bloc. Russia, the legal successor of the USSR, is neither a NATO, nor an EU member. The authors explore similarities and differences between countries of the Baltic Sea region in terms of their territory, population, GDP, foreign trade turnover and the number of regular armed forces. The article stresses the importance of international cooperation in increasing the growth rates of economic development of all countries of the Baltic Sea region.

    Full Text Available In the literary contemporary production of Bolivia, it takes place a phenomenon in which the works decouple of the literary tradition of the XX century and then, they leave the genres that, during at least the first half of the last century, were characterizing the Bolivian narrative. This way the indigenismo and the costumbrism are set aside to pass, in the first decade of the XXI century, to other genres that convey better the worries and the inquiries that the youngest writers face at the beginning of the present century. In the work La Toma del Manuscrito (2008, Sebastián Antezana checks and retakes the literary universal tradition to overcome the literary Bolivian tradition. Meanwhile, in La fotografía y la traducción, there is personified a process of unfolding and concealment of the artist – behind a camera, behind a language - contributing to the Bolivian narrative with a novel written from places hardly visited in this narrative of the XX century.

    Full Text Available Disintegration and integration processes of German culture of the end of XX and beginning of XXI are analyzed by giving examples of stage interpretations of mythological plots in theatres of present-day Germany. It is stated that pluralism and multidimensionality of the spiritual experience of modern cultural workers, both writers (such as V. Braun, S. Schutz, B. Strauss etc. and leading producers (D. Dorn, S. Nubling and others contribute to the drawing up of a special syncretic style of theatre staging, first of all with the use of the ancient material which is appropriate for it. Ancient myth, as one of the steadiest constants of the European literature, gives a universal key to the interpretation of various cultural and ethic-aesthetic phenomena that are irredundant to nothing else. There is a sociocultural context in which German spectators nowadays try to comprehend these dramaturgy phenomena; and there is a genuine stage director interpretations of them (in Aachen City Theatre, Dramatic Theatre of Hannover, Munich Chamber Theatre etc. that not only lead to the decanonization of the classic model, but also pinpoint problematique of these performances.

La formulación e implementación de la Doctrina Bush, la proyección unipolar de Estados Unidos, el reemerger de las capacidades rusas, la formación de nuevas redes de alianzas y la evolución de política exterior rusa de la era Putin pusieron a las dos potencias en curso de colisión. Como resultado se generó un conflicto que se ha expresado en espacios muy importantes del Medio Oriente, el Cáucaso y Europa oriental. La política exterior de la administración Obama representa un proceso de ajuste al nuevo contexto, priorizando la combinación pragmática de instrumentos del poder duro y el poder blando, y un multipolarismo guiado. La configuración resultante del sistema internacional tiene matices muy fuertes de una guerra fría.

A partir de un conjunto de referencias y reflexiones sobre la educación superior (particularmente en Venezuela se discute la necesidad de cambio en la praxis educativa universitaria. Se observan deficiencias en la ejecución actual de los estudiantes universitarios de pregrado, tanto al inicio como al final de sus estudios, deficiencias que el autor atribuye a la prevalencia del modelo asociacionista del aprendizaje. Si bien se considera que existen cambios en el campo teórico-reflexivo orientados por los aportes cognitivos y constructivistas, creemos que falta mucho trabajo y reflexión para llevar estos aportes al aula universitaria. Finalmente en función de lo expuesto, se presentan algunas reflexiones orientadas a un modelo de aula universitaria en el cual se pase del énfasis en los productos al énfasis en los procesos. Esto se considera como un reto para el siglo XXI.

    2016-01-01

    For any conformally compact manifold with hypersurface boundary we define a canonical renormalized volume functional and compute an explicit, holographic formula for the corresponding anomaly. For the special case of asymptotically Einstein manifolds, our method recovers the known results. The anomaly does not depend on any particular choice of regulator, but the coefficients of divergences do. We give explicit formulae for these divergences valid for any choice of regulating hypersurface; these should be relevant to recent studies of quantum corrections to entanglement entropies. The anomaly is expressed as a conformally invariant integral of a local Q-curvature that generalizes the Branson Q-curvature by including data of the embedding. In each dimension this canonically defines a higher dimensional generalization of the Willmore energy/rigid string action. We show that the variation of these energy functionals is exactly the obstruction to solving a singular Yamabe type problem with boundary data along the...

A las tradicionales guardas de un solo color y cuya única función era la de unir el libro a las cubiertas o tapas (función original de las guardas de todo libro, se les ha ido añadiendo otro tipo de guardas, en este caso, ilustradas y con una novedosa función: la de formar parte de la historia. Son pues, en algunos álbumes, y sorprendentemente también en algunos libros ilustrados, elementos fundamentales para que el lector pueda inferir significados y actualizar el texto. Nuestros objetivos estaban claros: nos propusimos analizar estas guardas, redefinirlas, categorizarlas. A su vez, se vislumbraba un nuevo lector modelo considerado «estrategia textual» en un mundo editorial que se hace eco de estos cambios y que forma parte de esta revolución en el concepto de libro como objeto.

Sin embargo, esa inversión económica no parece haber impactado en la mejora de la calidad de la educación básica. Se ha afirmado que los docentes son, simultáneamente, parte del problema y de la solución. Son parte del problema en virtud de su falta de preparación, del corporativismo, de la resistencia a las reformas. Pero deben ser parte de la solución porque sin la participación, compromiso y dedicación de los profesores será imposible superar los problemas de inequidad y calidad. Un sistema educativo nunca será mejor que los maestros con que cuenta. En este artículo describimos, desde Argentina, la historia de la formación docente, las políticas educativas recientemente diseñadas y la propuesta de una escuela futura que debe ser la custodia de los valores humanos en el futuro.

    Resumen. En el presente artículo se desarrollan algunas ideas y propuestas para el ejercicio de un liderazgo educativo que pueda asumir los principales retos de la educación superior en el siglo XXI. Se retoman en esta reflexión los compromisos de las universidades en la construcción de sociedades más justas y equitativas acordes a las necesidades y exigencias de un momento histórico caracterizado por los escenarios de la globalización y el desarrollo científico tecnológico. Se destacan por lo tanto, los vínculos permanentes entre la educación y el desarrollo social y económico; se retoman los planteamientos formulados en la Conferencia Mundial sobre la Educación Superior en 1998, los cuales evidencian los alcances e implicaciones de los principales desafíos que enfrenta la educación en el siglo XXI, por lo cual es de vital importancia un tipo de liderazgo que responda efectivamente a estos retos mediante acciones beligerantes, oportunas, participativas y concertadas.

     

    Abstract. In this article, we are developing some ideas and proposals for an educational leadership exercise in order to assume higher education´s main challenges in the XXI century. In this reflection we are taking into consideration the universities´commitments in the construction of more fair and equitable societies according to its necessities and demands in a historical moment distinguished by globalization and scientific technological development. Therefore, we have to emphasize the permanent links between education and economic and social development; besides, we take back some of the ideas presented at the higher education world conference in 1998, which evidenced the implications of the main challenges that education faces in the XXI century. For that reason it is of vital importance, a type of leadership that responds effectively to those challenges through belligerent, participative and precise actions.

Especialmente, nos referimos al uso de las estrategias de persuasión (ethos, pathos, logos así como al abundante uso de figuras retóricas. Tales parámetros unidos a los recursos que ofertan las tecnologías emergentes otorgan una enorme creatividad y aportan aspectos humanistas a la comunicación en red, claves de la fuerza persuasiva que caracteriza a estas plataformas online. De esta forma podemos hablar del usuario de redes como el nuevo «rétor» del siglo XXI.

    Full Text Available As novas tecnologias e a globalização vêm trazendo a possibilidade de estruturas mais democráticas de comunicação, produção e consumo, assim como de novos padrões de sociabilidade e de novas formas de atuação política. Na área da  mídia, a internet tende a minar o poder da indústria cultural, bem como seus efeitos  alienantes. Essa parece ser a tendência no Ocidente, no século XXI. No Brasil, no  entanto, o tipo de oligopolização do setor de comunicações existente tem mantido  um predomínio da mídia televisiva tradicional (aberta e paga não encontradiço  em países avançados. Não se trata de mera sobrevida de um padrão antigo em um  mundo em transição. Há uma articulação perversa dessa mídia com as exigências  do capitalismo pós-industrial, que se expressa sobremaneira nos momentos do lazer  e do consumo dos jovens e das crianças. Ocorre, pois, um paradoxo, talvez típico da  pós-modernidade brasileira, que, em um extremo, abriga um consumidor – cidadão  muito crítico, e no outro, técnicas de indução ao  consumismo, especialmente o infantil; ele é o tema de nossa reflexão.

    Full Text Available RESUMO: Interrogando-se sobre o lugar da filosofia de Theodor W. Adorno no âmbito do pensamento crítico contemporâneo, o presente artigo procura dar conta dos revezes da recepção político-filosófica da dialéctica negativa (das posturas críticas de Habermas, Lyotard ou Agamben às mais favoráveis de Jameson e Holloway e discutir a sua relevância actual. Defender-se-á que a politização do pensamento adorniano é possível, muito embora as suas valências críticas não se restrinjam a essa possibilidade. Hoje, a dialéctica negativa funcionaria também como antídoto contra os atalhos tomados pelas correntes "voluntarista" (Peter Hallward, "messiânica" (Agamben e "ontológica" (realismo especulativo da filosofia, à entrada do século XXI. Contudo, atendendo a que a relação entre teoria e prática é complexa em Adorno, a sua relevância actual ressaltaria em relação com as reacções críticas que o movimento do "realismo especulativo" tem suscitado. Em diálogo com alguns dos seus interlocutores (Markus Gabriel e Adrian Johnston, sugere-se que o desenvolvimento de uma "dialéctica constelar" depende da introdução de um elemento destotalizador no seio do diagnóstico radical - a um só tempo materialista e transcendental - da dialéctica negativa.

    Full Text Available O artigo discute a produção do conhecimento no século XXI, a partir da crise entre o paradigma clássico e o emergente. Destaca a incompetência da ciência para a solução dos principais problemas decorrentes do avanço científico, em especial o fenômeno da exclusão social. Analisa o princípio da complexidade e a sua relação com a construção de uma nova ética para o futuro. Mostra a incapacidade da disciplinaridade para dar conta dos problemas decorrentes do avanço científico deste século. Enfatiza a interdisciplinaridade para um primeiro passo na solução dos mesmos e, como transposição paradigmática, valoriza o princípio da transdisciplinaridade. Propõe os conceitos de permacultura, desenvolvimento sustentável, biologia do conhecimento e ecologia social como ferramentas para concretizar a interdisciplinaridade na produção do conhecimento. Conclui que a expansão de formas de democracia participativa é uma alternativa de gestão pública útil para equacionar o problema da exclusão social. E que se trata de um mecanismo de participação popular que permite às comunidades atuarem no controle público do Estado e do governo, e podem criar novas perspectivas de vida pública.

The basic types of casting alloys were taken into account. Changes in the production volume and structure over the period of the analysed 15 years were pointed out with respect to countries leading in foundry production. The topmost position in the world foundry industry is held by China for several years (with almost 45% share in the foundry market, the second place is taken by India (with almost 9% share. A distinct reduction in the shares of the once significant producers of castings, such as USA, Japan, Germany, Russia, Italy, or France, was observed over the 2000-2014 period. Poland had a share of 1.16% in 2000, and of 1.02% in 2014. Comparing the detailed data concerning the years 2000 and 2014, one can see that the fractions of castings made of ductile iron, cast steel, aluminium alloys, or magnesium alloys increase on a global scale, while such alloys as grey cast iron or malleable are in decline.

    Full Text Available El acuerdo de paz que puso fin a principios de los noventa al largo conflicto armado de El Salvador supone el inicio de un proceso de transformación institucional, legal y social cuyo eje central es la construcción de un Estado democrático de derecho. Aunque cabe afirmar que tanto la administración de justicia como la defensa de los derechos humanos han mejorado sustancialmente desde entonces, la situación actual del país a este respecto dista de ser satisfactoria. Así, de una parte, persisten en la sociedad salvadoreña, asolada por una persistente conflictividad social que padecen sobre todo los sectores de la población menos favorecidos, hábitos incompatibles con los propios de una cultura democrática. Y, de otra parte, se ha producido una cierta apropiación de las incipientes estructuras democráticas y también del nuevo lenguaje técnico-jurídico por una clase dirigente, en el ámbito profesional y político, no precisamente sensibilizada con los derechos e intereses de los más desprotegidos. La consecuencia lógica de tales circunstancias es el desapego, cuando no la desconfianza, de buena parte de la ciudadanía, y especialmente de las clases populares, hacia las instituciones democráticas, en general, y la Administración de Justicia, en particular.

  9. Does mathematical crystallography still have a role in the XXI century?

    Science.gov (United States)

    Nespolo, Massimo

    2008-01-01

    Mathematical crystallography is the branch of crystallography dealing specifically with the fundamental properties of symmetry and periodicity of crystals, topological properties of crystal structures, twins, modular and modulated structures, polytypes and OD structures, as well as the symmetry aspects of phase transitions and physical properties of crystals. Mathematical crystallography has had its most evident success with the development of the theory of space groups at the end of the XIX century; since then, it has greatly enlarged its applications, but crystallographers are not always familiar with the developments that followed, partly because the applications sometimes require some additional background that the structural crystallographer does not always possess (as is the case, for example, in graph theory). The knowledge offered by mathematical crystallography is at present only partly mirrored in International Tables for Crystallography and is sometimes still enshrined in more specialist texts and publications. To cover this communication gap is one of the tasks of the IUCr Commission on Mathematical and Theoretical Crystallography (MaThCryst).

    2016-02-01

    Full Text Available This paper’s main objective is to analyze the importance of strategic intelligence as a tool for decision making, applied to the operation of the State. In this sense, we highlight some elements related to the conceptual understanding of strategic intelligence, the problems that arise in the process of decision making, as well as the context in which this activity is presented as necessary to reduce uncertainty in the modern state, in an environment linked to the agency-structure dichotomy. Also, the distortion of the role of state intelligence stands out, especially considering the context of Latin American countries, and the need to link this task to the modernization of the State, as an essential part in the decision making process. We conclude that despite diagnosing some of the problems of decision-making in intelligence, and product demands through state actors in that task, there are a number of problems to ponder, among which stand out as a priority the legitimization of Intelligence as an integral and necessary part of the State, and the actions to improve the development of society as a whole.

    Full Text Available Knowledge is the most valuable asset of any organization in the Information Society, which allows the combination of the Knowledge Society and the Knowledge Economy. An advance in basic tools for the expansion of knowledge is like a rocket in the combustion stage, ready to launch the creation of wealth from knowledge. Historically, according to Del Moral (2007, the global economy has experienced a few years to this part, a major change, namely each time the assets are not physical or financial, but intellectual, to the extent that growth economic is driven by knowledge and ideas rather than traditional resources of land, raw materials, labor and capital. Once something is known, anyone can use it, and someone uses it does not prevent others from doing so. The challenge is, therefore, the development and effective management of knowledge, recognizing the nature of public good.

They represent channels inside the unipolar large-scale magnetic fields, formed by the rows of magnetic arcs directed to the neighboring fields of opposite polarity. The most important characteristics of the partings are revealed. It is found that--from the evolutionary and spatial point of view--the partings can transform to the coronal holes and visa versa. The classes of global, intersecting, and complex partings are identified.

    La recherche est axée sur la conception d’un modèle qui permettrait un développement de compétences génériques de l’enseignement à distance basé sur l’apprentissage autonome ce qui pourrait constituer un modèle de formation des ressources humaines de l’organisation du XXI ème siècle. L’étude réalisée est de caractère exploratoire et la proposition en première instance est l’identification des variables du modèle et, en deuxième instance, la construction de celui-ci. La méthodologie utilisée est un Delphi ayant rassemblé 30 experts en enseignement á distance. Le questionnaire a été proposé deux fois au même groupe. Une analyse factorielle a ainsi pu être réalisée. Les résultats de la recherche ont rendu possible un Modèle pour la Génération de Compétences Génériques de l’Enseignement á Distance basé sur l’apprentissage autonome grâce à la combinaison de neuf catégories de variables, dont l’importance a été démontrée. Toutefois, il est également apparu que cette relation devrait être maximisée par le biais de stratégies de contrôle dirigées vers les objectifs que l’on souhaite atteindre car il existe des facteurs inhérents aux catégories qui dépendent de conditions personnelles ainsi que du processus d’apprentissage personnel, ce qui pourrait devenir des obstacles au modèle.

    Ursula Elin Huws

    Full Text Available Costuma-se argumentar que a teoria do valor-trabalho de Marx não mais se aplica ao mundo contemporâneo, em que partes crescentes da população estão envolvidas em trabalho "imaterial" ou trabalho "digital". Este ensaio argumenta que essa teoria ainda é relevante, mas que, a fim de entender como ela pode ser aplicada ao trabalho imaterial e ao trabalho de modo mais geral, é necessário analisar criticamente os três principais componentes da teoria: a natureza particular de qualquer forma de trabalho, o valor que é criado por esse trabalho e os meios de subsistência do trabalhador. Essa análise nos permite não apenas distinguir entre "tempo de trabalho necessário" e mais-valia, mas também identificar o local de produção. Em um mundo em que novas atividades estão sendo constantemente trazidas para dentro da esfera das relações sociais capitalistas e novas mercadorias sendo produzidas, é importante identificar esses locais de produção e os trabalhadores que estão diretamente envolvidos na produção de mais-valia, porque são esses trabalhadores que têm o potencial, ao retirar seu consentimento, de se organizar de forma eficaz junto aos interesses comuns da classe trabalhadora global.

    Full Text Available La naturaleza ha sido fuente de fármacos desde el inicio de la historia y en muchas culturas lo sigue siendo hoy en día, como en la medicina tradicional china o la ayurveda. Por otra parte, un 50% de los fármacos actualmente usados en la medicina del mundo occidental derivan directa o indirectamente de la naturaleza, como la Aspirina® o el Taxol®. El camino que una sustancia recorre desde la naturaleza hasta convertirse en un nuevo fármaco es largo, laborioso y, en general, muy costoso. Los pasos más importantes a lo largo de este camino son el aislamiento de la fuente natural, elucidación estructural de los metabolitos aislados, sus ensayos en diferentes sistemas biológicos, hasta llegar a las fases clínicas y, finalmente - si todo va bien - la aprobación por la FDA o EMEA. La aparición de nuevas enfermedades infecciosas, la persistencia de enfermedades que aún no tienen tratamiento o la aparición de resistencia, amenazan la eficacia de los medicamentos actualmente en uso. La naturaleza nos puede proporcionar nuevas sustancias más eficaces y quizá con menos efectos secundarios para enfrentarnos a las enfermedades más impactantes de nuestro tiempo y del futuro.

    Traditionally, probabilistic risk assessments (PRAS) of severe accidents in nuclear power plants have considered initiating events potentially occurring only during full power operation. Recent studies and operational experience have, however, implied that accidents during low power and shutdown could be significant contributors to risk. In response to this concern, in 1989 the Nuclear Regulatory Commission (NRC) initiated an extensive program to carefully examine the potential risks during low power and shutdown operations. Two plants, Surry (pressurized water reactor) and Grand Gulf (boiling water reactor), were selected as the plants to be studied. The program consists of two parallel projects being performed by Brookhaven National Laboratory (Surry) and Sandia National Laboratories (Grand Gulf). The program objectives include assessing the risks of severe accidents initiated during plant operational states other than full power operation and comparing the estimated risks with the risk associated with accidents initiated during full power operation as assessed in NUREG-1150. The scope of the program is that of a Level-3 PRA. The subject of this report is the PRA of the Grand Gulf Nuclear Station, Unit 1. The Grand Gulf plant utilizes a 3833 MWt BUR-6 boiling water reactor housed in a Mark III containment. The Grand Gulf plant is located near Port Gibson, Mississippi. The regime of shutdown analyzed in this study was plant operational state (POS) 5 during a refueling outage, which is approximately Cold Shutdown as defined by Grand Gulf Technical Specifications. The entire PRA of POS 5 is documented in a multi-volume NUREG report (NUREG/CR-6143). The internal events accident sequence analysis (Level 1) is documented in Volume 2. The Level 1 internal fire and internal flood analyses are documented in Vols 3 and 4, respectively.

    During 1989, the Nuclear Regulatory Commission (NRC) initiated an extensive program to carefully examine the potential risks during low power and shutdown operations. The program includes two parallel projects being performed by Brookhaven National Laboratory (BNL) and Sandia National Laboratories (SNL). Two plants, Surry (pressurized water reactor) and Grand Gulf (boiling water reactor), were selected as the plants to be studied. The objectives of the program are to assess the risks of severe accidents initiated during plant operational states other than full power operation and to compare the estimated core damage frequencies, important accident sequences and other qualitative and quantitative results with those accidents initiated during full power operation as assessed in NUREG-1150. The scope of the program includes that of a level-3 PRA. A phased approach was used in the level-1 program. In phase 1 which was completed in Fall 1991, a coarse screening analysis including internal fire and flood was performed for all plant operational states (POSs). The objective of the phase 1 study was to identify potential vulnerable plant configurations, to characterize (on a high, medium, or low basis) the potential core damage accident scenarios, and to provide a foundation for a detailed phase 2 analysis. In phase 2, mid-loop operation was selected as the plant configuration to be analyzed based on the results of the phase 1 study. The objective of the phase 2 study is to perform a detailed analysis of the potential accident scenarios that may occur during mid-loop operation, and compare the results with those of NUREG-1150. The results of the phase 2 level 2/3 study are the subject of this volume of NUREG/CR-6144, Volume 6.

    To date, more than a quarter of tropical coral reefs of the World Ocean are believed to be totally de- stroyed. Given the present rates of reefs degradation, this value may be doubled in the nearest 30 years. For the essential part of coastal community, the destruction of coral ecosystems implies the loss of the major food sources, natural protection from storms, and significant (if not the only) revenue from exploi- tation of reefs especially in tourism industry. Finally, the disappearance of low-laying coral islands may threat the local communities by deprivation of living space. Global negative effects include temperature anomalies of sea surface waters and an increase of atmospheric CO2 concentration leading to ocean acidification. Local negative effects are related to in- crease of sedimentation and eutrophication, cyclone and storm passes, coral diseases, chemical pollution, mechanical destruction of corals by humans, anthropogenic depletion of functional groups of fish and invertebrates. An entire set of responses of coral ecosystems to stressful factors on the levels of both separate taxa and ecosystem is discussed. An analysis of published data suggests that with high probability the tropical coral communities will come to collapse stage by the middle of the current century at more than 50% of the area of their biogeographic range, especially in the regions of dense human population. At the most optimistic scenario, complex effect of reviewed negative factors will result in coral ecosystems main- taining in some areas. However, after global transformations, these ecosystems will be dominated by the most resistant taxa, mainly massive and encrusting forms of long-lived species with low growth rates and high competitive ability. Among such taxa, Poritidae demonstrates the highest adaptive capability. At the most pessimistic scenario, scleractinian communities will be replaced by alternative communities of macroalgae and non-calcareous anthozoans.

This fact contributed to the problem of violent crime against children has been actively developed in American criminology. The following article is devoted to mortality from homicides among children under the age of 5 years old in the United States of America. Statistical reports of the Federal Bureau of Investigation during the period of 1980-2013 have been used as an empirical base for research. Carried out a critical analysis of a wide range of research of American specialists in various branches of science (criminologists, sociologists, psychiatrists, physicians, devoted to the problems of infanticide in the United States. The basic parameters of infanticide, the dynamics and characteristics of this type of crime. Revealed a rather complicated dynamics of infanticide in the United States for a designated length of chronological period’s ups and downs in the development of this type of crime. Victimization characteristics of children died of homicides as per sex, age and race have been presented. It is found that among American children under the age of 5 years, the greatest risk of becoming a victim of premeditated murder was in children under the age of 1 year. Generalized characteristics of criminals having committed infanticide during this period of time as per sex, kinship of the victim, means used to murder have been revealed. This study found that during the period under review the chronological development of the United States of persons detained by the police for the murder of a child under the age of 5 years, which is numerically dominated by men. These statistics can be traced in all age groups of persons who have committed infanticide in the United States in the 1980-2013 periods

    The Caspian Sea - the unique largest enclosed inland body of water on Earth. Significant periodic sea level fluctuations are a typical feature of the sea. In the XIX-XX centuries a number of comprehensive studies of the Caspian Sea was carried out. The results are published in the papers, monographs and climatic atlases. But a number of fundamental questions about the features of the hydrological regime of the Caspian Sea is still open: 1. How does the water circulation change during the level variations? 2. What is the effect of heterogeneity of evaporation from the water surface on the formation of the flow field in the conditions of long-term level changes? 3. How does the water salinity regime change depending on the sea level position, water circulation, river flow and different climatic influences? 4. What is the effect of extreme events (multi-hazards) (ice, storms, destruction of the coasts) on coastal infrastructure? In 2016, the project aims to study hydrological regime extreme effects of the Caspian Sea was supported by the Russian Foundation for Basic Research. Within this project all of the above problems will be solved. Geographic information system "Caspian Sea" for the storage and data processing, including a database of primary oceanographic information for the period of instrumental observations (1897-2013), cartographic database (1921-2011) and tools for multidimensional analysis of spatio-temporal information is the basis of the study. The scheme of interconnected hydrodynamic models (Caspian Sea MODel - Ocean Model - Wind wave model) was developed. The important factors are taken into account in the structure of the models: long-term and seasonal dynamics of the sea waves parameters, new long-term values of evaporation from the shallow waters areas of the Caspian Sea, water circulation.

Este trabajo propone ilustrar el desarrollo del pensamiento humanista en América Latina y Cuba través de sus máximos exponentes y plantear dicha proyección en la Salud Pública cubana. Con el marxismo el humanismo adquirió un perfil proletario, se desentrañaron científicamente los mecanismos subhumanizadores del capitalismo y se indicaron las posibles vías de su superación. El humanismo es una concepción filosófica en al cual el hombre es su centro, la dignidad de las personas, las capacidades y potencialidades del hombre. En el pensamiento marxista latinoamericano ha habido pujantes manifestaciones de autenticidad cuando hombres de distintas generaciones como Mella, Mariátegui, el Che o Fidel han utilizado el instrumental de análisis que ofrece la concepción dialéctico- materialista de la historia para interpretar sus respectivas circunstancias y tratar de transformarlas. El humanismo está indisolublemente ligado a la libertad, solidaridad e internacionalismo como valores humanos. La proyección humanística de la Salud Pública tiene el propósito de elevar gradualmente la salud de la población, de modo que contribuya a la elevación de su calidad de vida; al incremento de la calidad de los servicios, la satisfacción de la población y de los trabajadores de la salud; al perfeccionamiento de la gestión y la elevación de la eficiencia del sistema nacional de SaludThe term Humanism has been used to name all theories that hold, as main principle, the respect to the human being. This word has an undisputable

    There is no doubt that women education and attendance to university have facilitated their access to almost all the working sectors. At the same time, it has point out a break point between the traditional scenario and the actual reality, how achievements have been obtained thanks to day by day fight, little steps and advances give impulse to women to a full participation in the working area, diversifying her role in different fields and occupying in work market different roles that recently were exclusive for men. For example: army, truck drivers, miners and airplane pilots among others. However, not everything are lights in this reflection with an optimistic touch, there are shadows too, opposition, obstacles, impediments and difficulties in the society or in women herself that have to be avoided when they incorporate in different labour markets. The difficulties that women have been overcome and the gender inequality that still can be found, even in occidental societies, are something that concerns to all of us. We believe that it is necessary centuries to overcome certain aspects that, in some way, are impregnated in the society, life style, rules of conduct, culture, or simply learned by the people that are really difficult not only to elude them as to avoid them. Throughout this work some examples will be shown that corroborate this comment. This subject is wide, complex and difficult. For this reason, we will put a limit on it and we will focus on the Spanish society as a part of the western advanced societies. With regard to the working area, we will delimited this study to the engineering careers showing some allusive numbers, actual university studies in this field and related them to earlier decades. In this way, a comparative analysis on the evolution of this scenario can be established. There are many papers and manuscripts that talk about different aspects in female success, such as women in sport, highly gifted and women, etc. For this reason we are

    Aigner, M.; Heinrich, C.; Jüttler, B.; Pilgerstorfer, E.; Simeon, B.; Vuong, A.-V.

    Isogeometric Analysis uses NURBS representations of the domain for performing numerical simulations. The first part of this paper presents a variational framework for generating NURBS parameterizations of swept volumes. The class of these volumes covers a number of interesting free-form shapes, such as blades of turbines and propellers, ship hulls or wings of airplanes. The second part of the paper reports the results of isogeometric analysis which were obtained with the help of the generated NURBS volume parameterizations. In particular we discuss the influence of the chosen parameterization and the incorporation of boundary conditions.

    Volume 1 to the Department of Energy`s Programmatic Spent Nuclear Fuel Management and Idaho National Engineering Laboratory Environmental Management Programs Environmental Impact Statement evaluates a range of alternatives for managing naval spent nuclear fuel expected to be removed from US Navy nuclear-powered vessels and prototype reactors through the year 2035. The Environmental Impact Statement (EIS) considers a range of alternatives for examining and storing naval spent nuclear fuel, including alternatives that terminate examination and involve storage close to the refueling or defueling site. The EIS covers the potential environmental impacts of each alternative, as well as cost impacts and impacts to the Naval Nuclear Propulsion Program mission. This Appendix covers aspects of the alternatives that involve managing naval spent nuclear fuel at four naval shipyards and the Naval Nuclear Propulsion Program Kesselring Site in West Milton, New York. This Appendix also covers the impacts of alternatives that involve examining naval spent nuclear fuel at the Expended Core Facility in Idaho and the potential impacts of constructing and operating an inspection facility at any of the Department of Energy (DOE) facilities considered in the EIS. This Appendix also considers the impacts of the alternative involving limited spent nuclear fuel examinations at Puget Sound Naval Shipyard. This Appendix does not address the impacts associated with storing naval spent nuclear fuel after it has been inspected and transferred to DOE facilities. These impacts are addressed in separate appendices for each DOE site.

    During 1989, the Nuclear Regulatory Commission (NRC) initiated an extensive program to carefully examine the Potential risks during low Power and shutdown operations. The program includes two parallel projects being performed by Brookhaven National Laboratory (BNL) and Sandia National Laboratories (SNL). Two plants, Surry (pressurized water reactor) and Grand Gulf (boiling water reactor), were selected as the Plants to be studied. The objectives of the program are to assess the risks of severe accidents initiated during plant operational states other than full power operation and to compare the estimated core damage frequencies, important accident sequences and other qualitative and quantitative results with those accidents initiated during full power operation as assessed in NUREG-1150. The objective of this report is to document the approach utilized in the Surry plant and discuss the results obtained. A parallel report for the Grand Gulf plant is prepared by SNL. This study shows that the core-damage frequency during mid-loop operation at the Surry plant is comparable to that of power operation. We recognize that there is very large uncertainty in the human error probabilities in this study. This study identified that only a few procedures are available for mitigating accidents that may occur during shutdown. Procedures written specifically for shutdown accidents would be useful. This document, Volume 2, Pt. 2 provides appendices A through D of this report.

    The T-F and S/DOE Gladys McCall No. 1 well was the fourth in a series of wells in the DOE Design Wells Program that were drilled into deep, large geopressured-geothermal brine aquifers in order to provide basic data with which to determine the technological and economic viability of producing energy from these unconventional resources. This brine production well was spudded on May 27, 1981 and drilling operations were completed on November 2, 1981 after using 160 days of rig time. The well was drilled to a total depth of 16,510 feet. The target sands lie at a depth of 14,412 to 15,860 feet in the Fleming Formation of the lower Miocene. This report covers well production testing operations and necessary well workover operations during the February 1982 to October 1985 period. The primary goals of the well testing program were: (1) to determine reservoir size, shape, volume, drive mechanisms, and other reservoir parameters, (2) to determine and demonstrate the technological and economic viability of producing energy from a geopressured-geothermal brine aquifer through long-term production testing, and (3) to determine problem areas associated with such long-term production, and to develop solutions therefor.

    Se hace una revisión de lo que ha sido la evolución del sistema ocular en la especie humana desde las formas más primitivas de visión. Se observa que los ojos han venido sufriendo un proceso de maduración y excelencia, en gran parte ligado a las necesidades de cada especie. La percepción de colores y ondas electromagnéticas, por ejemplo, varía en ciertos animales según los propósitos alimenticios.

    El tamaño del ojo parece ir ligado al desarrollo del cerebro. La miopía que consiste en la presencia de un ojo más alargado, ha venido incrementándose en el último siglo. Aparentemente hay una asociación muy fuerte entre la presencia de miopía y el grado de culturización e inteligencia. Los pueblos más desarrollados presentan mayor incidencia de miopía, y ésta a su vez se incrementa con la escolaridad. Basados en estudios filogenéticos y epidemiológicos se esboza la hipótesis: «que el hombre del futuro será cada vez más miope y a su vez más inteligente».

    EVOLUCIÓN DEL SISTEMA OCULAR.

    El primer ser multicelular con «ojos» rudimentarios aparece en la mitad de la era proterozoica, es decir, hace 1500 millones de años y sólo hasta el mesozoico, hace apenas 248 millones de años, se desarrollan los primeros animales con cerebro y ojos**. En los últimos 40 millones emergen los primates predecesores de los humanoides

    Al igual que para muchas especies animales, a lo largo de la historia de la evolución, la exposición a la luz marcó un cambio dramático en el ciclo vital. El hombre salió de las cavernas, para acostumbrarse a la luz: sin luz no hay visión. La tierra ha sido bombardeada por ondas electromagnéticas desde su creación.

    La luz, entre otros fenómenos, es la responsable de uno de las manifestaciones más primitivas de vida y se traduce en las escalas inferiores como un simple fototropismo. El anterior mecanismo da origen a los primeros esbozos

    Full Text Available Resumo ----- Objetiva-se com este trabalho aprofundar o conhecimento sobre as parcerias intersetoriais entre Estado, mercado e sociedade civil, a partir da análise argumentativa de um caso, o projeto Geração XXI, a primeira ação afirmativa para jovens negros no Brasil. Este trabalho utiliza as teorias da argumentação, sobretudo a teoria da ação comunicativa de Habermas, para avaliar a validade dos discursos manifestados pelos diferentes parceiros e a capacidade destes de criar “situações dialógicas” que busquem possíveis soluções por vias argumentativas. O trabalho baseia-se numa pesquisa qualitativa que combinou a observação participante com entrevistas semiestruturadas. A conclusão apontará que, apesar de o projeto ter sido bem gerenciado desde o ponto de vista da racionalidade instrumental, houve falhas na construção de um significado aceitável por todos os colaboradores de conceitos-chave - ação afirmativa, gestão da diversidade e responsabilidade social, bem como nos procedimentos de comunicação institucionalizados, que afetaram negativamente os processos e resultados finais do projeto. ----- Articulating Affirmative Action Policies for Afro-descendants through Cross-Sector Partnerships: an argumentative analysis of the Geração XXI case ----- Abstract ----- The goal of this article is to deepen the knowledge on cross-sector partnerships that are articulated among the State, the market, and civil society, taking as the main focus the argumentative analysis of one case, Geração XXI, the first affirmative action program for black youngsters in Brazil.

    Traditionally, probabilistic risk assessments (PRA) of severe accidents in nuclear power plants have considered initiating events potentially occurring only during full power operation. Some previous screening analyses that were performed for other modes of operation suggested that risks during those modes were small relative to full power operation. However, more recent studies and operational experience have implied that accidents during low power and shutdown could be significant contributors to risk. During 1989, the Nuclear Regulatory Commission (NRC) initiated an extensive program to carefully examine the potential risks during low power and shutdown operations. The program includes two parallel projects being performed by Brookhaven National Lab. (BNL) and Sandia National Labs. (SNL). Two plants, Surry (pressurized water reactor) and Grand Gulf (boiling water reactor), were selected as the plants to be studied. The objectives of the program are to assess the risks of severe accidents initiated during plant operational states other than full power operation and to compare the estimated core damage frequencies, important accident sequences and other qualitative and quantitative results with those accidents initiated during full power operation as assessed in NUREG-1150. The objective of this volume of the report is to document the approach utilized in the level-1 internal events PRA for the Surry plant, and discuss the results obtained. A phased approach was used in the level-1 program. In phase 1, which was completed in Fall 1991, a coarse screening analysis examining accidents initiated by internal events (including internal fire and flood) was performed for all plant operational states (POSs). The objective of the phase 1 study was to identify potential vulnerable plant configurations, to characterize (on a high, medium, or low basis) the potential core damage accident scenarios, and to provide a foundation for a detailed phase 2 analysis.
