    Full Text Available La Convergencia Europea de Educación Superior supone unos cambios estructurales, metodológicos y técnicos muy importantes para la vida universitaria. La acción tutorial del profesorado universitario va a ser uno de los aspectos que será preciso readaptar y revitalizar. En el presente trabajo se define y justifica la tutoría como un quehacer relevante del profesor universitario. Se analizan, justifican y proponen las contribuciones y modelos de la tutoría en la Universidad, tomando como referencia y contextualizándolo en el espacio y el tiempo en el que se halla inmersa la Universidad actual, que no son otros que el Espacio Europeo de Educación Superior y la Sociedad del Conocimiento y de la Información. El rol tutorial que, de una u otra forma, siempre ha estado presente en la Universidad, es hoy especialmente demandado para responder a las nuevas necesidades y características del actual alumnado. Parece oportuno reflexionar sobre él subrayando toda su riqueza y significado en el actual contexto de la Educación Superior.

  4. Comparison of actual oxygen delivery kinetics to those predicted by mathematical modeling following stage 1 palliation just prior to superior cavopulmonary anastomosis.

    2015-02-01

    Optimizing systemic oxygen delivery (DO2) and hemodynamics in children with hypoplastic left heart syndrome (HLHS) is a clinical challenge. Mathematical modeling of the HLHS circulation has been used to determine the relationship between oxygen kinetic parameters and DO2 and to determine how DO2 might be optimized. The model demonstrates that neither arterial oxygen saturation (SaO2) nor mixed venous oxygen saturation (SvO2) alone accurately predicts DO2. Oxygen delivery kinetics predicted by previously described mathematical modeling were compared with actual patients' hemodynamic data. We sought to determine which patient derived parameters correlated best with DO2. Patients with HLHS who underwent cardiac catheterization prior to surgery to create a superior cavopulmonary anastomosis from 2007 to 2011 were identified. Hemodynamic data obtained were compared with the data derived from the mathematical model. Correlations between SaO2, SvO2, SaO2-SvO2, SaO2/(SaO2-SvO2), pulmonary-to-systemic blood flow ratio (Qp/Qs), and DO2 were evaluated using both linear and nonlinear analyses, and R(2) was calculated. Patients' data fit most aspects of the mathematical model. DO2 had the best correlation with SaO2/(SaO2-SvO2; R(2) = 0.8755) followed by SaO2 -SvO2 (R(2) = 0.8063), while SaO2 or SvO2 alone did not demonstrate a significant correlation as predicated by the mathematical model (R(2) = 0.09564 and 0.4831, respectively). SaO2/(SaO2 -SvO2) would be useful clinically to track changes in DO2 that occur with changes in patient condition or with interventions. © 2014 John Wiley & Sons Ltd.

    La experiencia clínica está demostrando que las indicaciones y las contraindicaciones del trasplante cardíaco están en constante cambio, debido principalmente a los avances en los cuidados pre, per y postoperatorios, a los nuevos fármacos y otras novedosas alternativas terapéuticas. La clase funcional (NY HA del paciente es poco precisa para indicar el trasplante cardíaco, por lo que se precisa de otras determinaciones, como el consumo máximo de oxígeno: VO2 máx < 10 ml/kg/min conlleva un mortalidad hospitalaria elevada. Asimismo, la fracción de eyección ventricular izquierda disminuida (FEVI < 20% no debe considerarse como el indicador principal para establecer la indicación de trasplante, siendo necesario valorar otros factores de riesgo preoperatorios. En la última década, la experiencia ha puesto de manifiesto que algunas de las contraindicaciones absolutas, antes vigentes, no siempre deben desaconsejar el trasplante cardíaco.

The fecal immunohistochemical tests (FIT) to detect blood in the stool have been more specific that guaiac fecal occult blood tests (gFOBT), because of they react only with human hemoglobin. Reasonable evidence has existed that the FIT has been superior than gFOBT with respect to acceptance of the population, the detection rate and positive predictive value of adenomas and CRC. Mortality by CRC has decreased with the screening of FIT screening. The double contrast barium enema has been a valid cost-effective technique in the programs of early detection and diagnostic of colonic pathologies [Spanish] Una revision de la evidencia disponible es realizada en torno a las indicaciones apropiadas y criterios de calidad en colonoscopia. Esta revision ha servido como instrumento a los programas de deteccion temprana, diagnostico y tratamiento de las enfermedades colonicas en las unidades de endoscopia y endoscopistas que han efectuado colonoscopia. El cancer colorrectal (CCR) ha sido una enfermedad prevenible basada en los efectos de factores de riesgo manipulables y tamizaje para la deteccion temprana del mismo. La historia familiar, edad avanzada, el sexo masculino, el numero de tamano de los adenomas, la presencia de un componente velloso, la displasia de alto grado y la localizacion proximal son asociados con un aumento significativo del riesgo para CCR. La indicacion inapropiada/innecesaria del procedimiento y la falta de uniformidad de criterios, ignorando las guias clinicas internacionales de indicacion de colonoscopia, ha causado un colapso de las unidades de endoscopia en el mundo en perjuicio de la calidad. Los indicadores de calidad aplicables son definidos localmente para establecer con base en la evidencia disponible, los requisitos minimos que deben cumplir las unidades de endoscopia y endoscopistas que han participado en los programas de cribado de CCR.

    Full Text Available RESUMEN El uso de medicamentos en indicaciones no registradas (INR, conocido como uso “off-label”, es una práctica que genera problemas de uso racional y de acceso cuando no existen alternativas disponibles. Los sistemas de salud deben gestionar esta realidad, sobre todo cuando se trata de decisiones de cobertura, buscando minimizar los riesgos para la salud y estableciendo de forma clara los papeles y las responsabilidades de los agentes involucrados. El Ministerio de Salud y Protección Social de Colombia (MinSalud, junto con con la Universidad Nacional de Colombia y expertos nacionales, diseñaron una propuesta de modelo de gestión del uso de medicamentos en indicaciones no registradas (off-label y su potencial reembolso con recursos públicos, teniendo en cuenta prácticas internacionales y la realidad nacional. El modelo de gestión es no punitivo y está orientado a la promoción del uso racional de estos medicamentos, de forma que se reduzcan las barreras al acceso cuando su uso está respaldado por pruebas cientificas de calidad. El modelo incorpora elementos de garantías bioéticas del paciente, los papeles y las responsabilidades del prescriptor y de las entidades de gobierno.

    Full Text Available Los potenciales evocados (PE son procedimientos neurofisiológicos más sensibles que específicos, objetivos, fidedignos, reproducibles y seguros que se emplean para evaluar la integridad de las vías sensoriales y motoras periféricas y centrales. La integridad de estas vías se determina midiendo la latencia de los eventos eléctricos producidos por estímulos adecuados y registrados después de ser promediados digitalmente. Las indicaciones médicas y quirúrgicas incluyen condiciones en las cuales el diagnóstico, la determinación del riesgo de secuelas neurológicas en pacientes comatosos y anestesiados y la determinación del curso de la enfermedad y respuesta al tratamiento no se pueden definir con el examen neurológico y otras pruebas neurodiagnósticas.Evoked potentials (EP are more sensitive than specific, safe, objective and reproducible neurophysiologic techniques to assess integrity of peripheral and central sensory and motor pathways.

    Full Text Available Las indicaciones para realizar episiotomía en los partos vaginales es un tema controvertido que requere revisión en todas partes del mundo. En 1995, en la provincia de Neuquén, Argentina, se elaboraron normas para la atención del parto de bajo riesgo, una de las cuales recomendaba reservar la episiotomía para los casos de alto riesgo de desgarro. Este estudio de cohortes retrospectivo se diseñó con objeto de comparar los criterios que se utilizaron en 1996 como indicación de episiotomía en los centros de maternidad del subsector público de esa provincia así como el efecto de la paridad y otras variables en la frecuencia de esa intervención. Se examinaron 7 513 registros del Sistema Informático Perinatal, que representan 70% del total de partos atendidos ese año. Se excluyeron 830 correspondientes a partos por cesárea. Los 6683 registros restantes se dividieron en ocho grupos según la institución donde se atendió el parto. Se calcularon las tasas de incidencia de episiotomía en esos grupos y se realizó una regresión de Poisson a fin de ajustar las tasas por peso al nacer de los niños, paridad y edad de la madre, y forma de presentación y de terminación del parto. Tomando al Hospital Neuquén como base por ser el más complejo y atenderse allí el mayor número de partos, dos hospitales tuvieron incidencias de episiotomía correspondientes a 70% (IC95%, 62 a 79 y 67% (IC95%, 57 a 78 de las de ese hospital. Otros dos hospitales tuvieron incidencias más altas que el Neuquén por 28% (IC95%, 13 a 45 y 17% (IC95%, 2 a 35, mientras que en los hospitales restantes no se observaron diferencias significativas. Mediante regresión estratificada según el número de partos vaginales previos, se observó que la variable con mayor efecto en la indicación de episiotomía fue la paridad. En las nulíparas, las tasas no mostraron diferencias según el lugar donde se atendió el parto, pero en las primíparas sí hubo diferencia, aun m

La comprensión de ciertas reglas de evidencia, es necesaria para la correcta interpretación de la literatura sobre causas, pruebas diagnósticas, y estrategias de tratamiento. El objetivo primordial de esta búsqueda es hacer un protocolo para las indicaciones de un ecocardiograma en la práctica médica, y la educación de ésta en la conducta de los médicos generales en Colombia. Las buenas prácticas son ejemplos de iniciativas, actividades o modelos de funcionamiento que están en marcha en todo el mundo como lo corrobora la evidencia. Objetivo: la ecocardiografía es, en la actualidad, el método de diagnóstico de elección para el estudio de la anatomía y la función cardiaca. Desde su introducción en la práctica clínica hospitalaria hace más de tres décadas, la difusión de esta técnica ha sido tal, que hoy se considera como una herramienta importante en la cardiología asistencial porque proporciona información anatomofuncional fidedigna y diagnósticos, y decide el tratamiento para la resolución de la enfermedad cardiovascular. Su progresivo desarrollo ha permitido extender su uso en todos los campos que afectan las enfermedades cardiovasculares. El objetivo siempre busca ayudar a los clínicos a tomar decisiones en situaciones concretas, garantizándoles que se tome la mejor en cada caso y la que más se fundamente en las pruebas aportadas por los estudios científicos más válidos. Con base en lo anterior, se recopilaron diferentes estudios, task force y guías de manejos representativos de la literatura mundial.Introduction: clinical practice based on evidence takes off emphasis in intuition; clinical experience and rational

    Full Text Available http://dx.doi.org/10.5007/1808-1711.2016v20n1p61 In what follows, I present only part of a program that consists in developing a version of actualism as an adequate framework for the metaphysics of intentionality. I will try to accommodate in that framework suggestions found in Kripke’s works and some positions developed by Amie Thomasson. What should we change if we accept “fictional entities” in the domain of the actual world? Actualism is the thesis that everything that exists belongs to the domain of the actual world and that there are no possibilia. I shall defend that there are abstract artefacts, like fictional characters, and institutions. My argument could be seen as a version of Moore’s paradox: it is paradoxical to say: “I made (created it, but I do not believe it exists”. Moreover, there are true sentences about them. I will examine what it means to include abstract artefacts in the domain of the actual world. I favour a use of “exist” that includes beings with no concrete occupation of tri-dimensional space; to exist, it is enough to have been introduced at some moment in history. Abstract artefacts, like fictional characters, exist in that sense. I argue that it is important to distinguish two perspectives (internal and external in order to clarify the kind of knowledge we have of fictional characters. However, their existence presupposes a relation of dependence to a material basis and the mental activities of many people.

En primer lugar, se describe la comunidad de usuarios a nivel global, focalizando en el uso actual que el software ha alcanzado en Argentina: la cantidad de implementaciones disponibles, su evolución, el tipo, tamaño y variedad de los desarrollos existentes, así como su aplicación a la gestión de repositorios digitales de ciencia y tecnología en el ámbito de las instituciones científicas, tecnológicas y de educación superior en Argentina. En segundo lugar, se detallan las acciones llevadas a cabo a partir de la creación del Centro Nacional de Promoción de Greenstone en Argentina en 2009. Datos recabados en encuestas realizadas permitieron observar que las razones predominantes para elegir esta plataforma fueron, entre otras, su facilidad de instalación y configuración, su bajo nivel de requerimiento tecnológico, la generalizada escasez de recursos humanos dedicados a esta actividad, y la complejidad que presentaban los softwares alternativos existentes en ese momento. A lo largo de estos 8 años, tanto los repositorios digitales como los sistemas que los soportan evolucionaron drásticamente, modificando el escenario actual. Paralelamente, en 2016 la nueva versión mayor de Greenstone implementó una reingeniería completa del software para su adaptación a las tecnologías en uso: XML, XSLT, Web-services y Java. Como consecuencia de esto, la comunidad de desarrollo local se plantea nuevos desafíos para la migración de las bibliotecas digitales y repositorios implementados con versiones anteriores.

  9. Estimations of actual availability

    2001-01-01

    Adaptation of working environment (social, organizational, physical and physical) should assure higher level of workers' availability and consequently higher level of workers' performance. A special theoretical model for description of connections between environmental factors, human availability and performance was developed and validated. The central part of the model is evaluations of human actual availability in the real working situation or fitness for duties self-estimation. The model was tested in different working environments. On the numerous (2000) workers, standardized values and critical limits for an availability questionnaire were defined. Standardized method was used in identification of the most important impact of environmental factors. Identified problems were eliminated by investments in the organization in modification of selection and training procedures in humanization of working .environment. For workers with behavioural and health problems individual consultancy was offered. The described method is a tool for identification of impacts. In combination with behavioural analyses and mathematical analyses of connections, it offers possibilities to keep adequate level of human availability and fitness for duty in each real working situation. The model should be a tool for achieving adequate level of nuclear safety by keeping the adequate level of workers' availability and fitness for duty. For each individual worker possibility for estimation of level of actual fitness for duty is possible. Effects of prolonged work and additional tasks should be evaluated. Evaluations of health status effects and ageing are possible on the individual level. (author)

    1985-01-01

    Sciatica caused by root entrapment in the lateral recess was named superior facet syndrome by Epstein in 1972. Few reports on this subject based on large numbers of cases have been documented to date. Of the patients with sciatica, 32 patients were diagnosed to have root entrapment at the lateral recess L 5 or/and S 1 lumbar spine. Out of 32 patients, 20 patients were operated on and the lateral entrapment was recognized in all of surgical cases. Neuroradiological findings, especially of metrizamide CT (met. CT), were documented in detail. Thirty two patients were classified in three types according to radiological findings. They were congenital or developmental, degenerative, and combined type, respectively, Fourteen cases belonged to the congenital type, 13 to the degenerative and 5 to the combined type. Each group had the mean ages of 23.4, 53.8, and 36.8 years old, respectively. Of 32 cases the entrapment occured in 47 L 5 roots and 11 S 1 roots. There was no remarkable laterality. In operation the unroofing of the lateral recess were done and the sciatica subsided postoperatively in all of surgical cases. Met. CT revealed extreme medial protrusion of the superior articular joint in 18 of 24 cases(75%) and none filling of the root in the lateral recess in 21 of 24 cases (87.5%). In the degenerative type, met. CT showed some degenerative changes that were hypertrophy or deformity of the articular joints and spur formation of the vertebral body. In contrast to met. CT, metrizamide myelography revealed only slight changes, which were poor filling of the root before it turned out the pedicle of lateral compression of the root. In plain films or lumbar spine articular joints at Lsub(4/5) were formed in coronal plane in 69% of cases of the L 5 root entrapment. Met. CT using ReView technique was of great diagnostic value in superior facet syndrome. (author)

  9. Hypochondria as an actual neurosis.

    Science.gov (United States)

    Nissen, Bernd

    2017-09-27

    Freud defined hypochondria as an actual neurosis. In this paper the actual neurosis will be interpreted as unbound traumatic elements which threaten the self. In severe hypochondria, breakdowns have occurred, as outlined by Winnicott. The nameless traumatic elements of the breakdown have been encapsulated. The moment these encapsulated elements are liberated, an actual dynamic takes place which threatens the self with annihilation. Projective identification is not possible because no idea of containment exists. The self tries to evacuate these elements projectively, thus triggering a disintegrative regression. However, the object of this projection, which becomes a malign introject, is felt to remove the remaining psychical elements, forcing the worthless residue back into the self. In a final re-introjection, the self is threatened by unintegration. To save the self, these elements are displaced into an organ which becomes hypochondriacal, an autistoid object, protecting itself against unintegration and decomposition. An autistoid dynamic develops between the hypochondriac organ, the ego and the introject. Two short clinical vignettes illustrate the regressive dynamical and metapsychological considerations.

    Residential thermostats have been a key element in controlling heating and cooling systems for over sixty years. However, today's modern programmable thermostats (PTs) are complicated and difficult for users to understand, leading to errors in operation and wasted energy. Four separate tests of usability were conducted in preparation for a larger study. These tests included personal interviews, an on-line survey, photographing actual thermostat settings, and measurements of ability to accomplish four tasks related to effective use of a PT. The interviews revealed that many occupants used the PT as an on-off switch and most demonstrated little knowledge of how to operate it. The on-line survey found that 89% of the respondents rarely or never used the PT to set a weekday or weekend program. The photographic survey (in low income homes) found that only 30% of the PTs were actually programmed. In the usability test, we found that we could quantify the difference in usability of two PTs as measured in time to accomplish tasks. Users accomplished the tasks in consistently shorter times with the touchscreen unit than with buttons. None of these studies are representative of the entire population of users but, together, they illustrate the importance of improving user interfaces in PTs.

    2014-05-01

    The most actual goals of geoethics have been formulated as results of the International Conference on Geoethics (October 2013) held at the geoethics birth-place Pribram (Czech Republic): In the sphere of education and public enlightenment an appropriate needed minimum know how of Earth sciences should be intensively promoted together with cultivating ethical way of thinking and acting for the sustainable well-being of the society. The actual activities of the Intergovernmental Panel of Climate Changes are not sustainable with the existing knowledge of the Earth sciences (as presented in the results of the 33rd and 34th International Geological Congresses). This knowledge should be incorporated into any further work of the IPCC. In the sphere of legislation in a large international co-operation following steps are needed: - to re-formulate the term of a "false alarm" and its legal consequences, - to demand very consequently the needed evaluation of existing risks, - to solve problems of rights of individuals and minorities in cases of the optimum use of mineral resources and of the optimum protection of the local population against emergency dangers and disasters; common good (well-being) must be considered as the priority when solving ethical dilemmas. The precaution principle should be applied in any decision making process. Earth scientists presenting their expert opinions are not exempted from civil, administrative or even criminal liabilities. Details must be established by national law and jurisprudence. The well known case of the L'Aquila earthquake (2009) should serve as a serious warning because of the proven misuse of geoethics for protecting top Italian seismologists responsible and sentenced for their inadequate superficial behaviour causing lot of human victims. Another recent scandal with the Himalayan fossil fraud will be also documented. A support is needed for any effort to analyze and to disclose the problems of the deformation of the contemporary

  17. Writing superiority in cued recall

    2013-10-01

    Full Text Available In list learning paradigms with free recall, written recall has been found to be less susceptible to intrusions of related concepts than spoken recall when the list items had been visually presented. This effect has been ascribed to the use of stored orthographic representations from the study phase during written recall (Kellogg, 2001. In other memory retrieval paradigms, either better recall for modality-congruent items or an input-independent writing superiority effect have been found (Grabowski, 2005. In a series of four experiments using a paired associate (PA learning paradigm we tested (a whether output modality effects on verbal recall can be replicated in a paradigm that does not involve the rejection of semantically related intrusion words, (b whether a possible superiority for written recall was due to a slower response onset for writing as compared to speaking in immediate recall, and (c whether the performance in PA word recall was correlated with performance in an additional episodic memory task. We found better written recall in the first half of the recall phase, irrespective of the modality in which the material was presented upon encoding. An explanation based on longer response latencies for writing and hence more time for retrieval could be ruled out by showing that the effect persisted in delayed response versions of the task. Although there was some evidence that stored additional episodic information may contribute to the successful retrieval of associate words, this evidence was only found in the immediate response experiments and hence is most likely independent from the observed output modality effect. In sum, our results from a PA learning paradigm suggest that superior performance for written versus spoken recall cannot be (solely explained in terms of additional access to stored orthographic representations from the encoding phase. Our findings rather suggest a general writing-superiority effect at the time of memory

  18. Prosopomorphic vessels from Moesia Superior

    2008-01-01

    Full Text Available The prosopomorphic vessels from Moesia Superior had the form of beakers varying in outline but similar in size. They were wheel-thrown, mould-made or manufactured by using a combination of wheel-throwing and mould-made appliqués. Given that face vessels are considerably scarcer than other kinds of pottery, more than fifty finds from Moesia Superior make an enviable collection. In this and other provinces face vessels have been recovered from military camps, civilian settlements and necropolises, which suggests that they served more than one purpose. It is generally accepted that the faces-masks gave a protective role to the vessels, be it to protect the deceased or the family, their house and possessions. More than forty of all known finds from Moesia Superior come from Viminacium, a half of that number from necropolises. Although tangible evidence is lacking, there must have been several local workshops producing face vessels. The number and technological characteristics of the discovered vessels suggest that one of the workshops is likely to have been at Viminacium, an important pottery-making centre in the second and third centuries.

  19. Double elevator weakening for unilateral congenital superior oblique palsy with ipsilateral superior rectus contracture and lax superior oblique tendon.

    Science.gov (United States)

    Khan, Arif O

    2012-06-01

    In unilateral congenital superior oblique palsy, a large hypertropia is sometimes associated with ipsilateral contracture of the superior rectus muscle and apparent overaction of the contralateral superior oblique. Ipsilateral double elevator weakening is one surgical approach; however, this procedure could compromise supraduction. We report a series of three consecutive patients who underwent ipsilateral superior rectus and inferior oblique recessions for unilateral superior oblique palsy. Intraoperatively, all three patients were found to have a lax ipsilateral superior oblique tendon. Postoperatively, all three patients had satisfactory correction of the hypertropia and abnormal head position with minimal supraduction defect. This procedure seems to be an acceptable initial surgical option for treating congenital superior oblique muscle palsy with ipsilateral contracture of the superior rectus muscle, even when the ipsilateral superior oblique tendon is lax.

Tampoco la indicación quirúrgica de la IT está bien definida. Hay consenso en intervenir la IT grave durante la cirugía de valvulopatías izquierdas. Sin embargo, existe controversia cuando el grado de insuficiencia es menor o el anillo tricuspídeo está dilatado. La reparación valvular es la técnica de elección en la IT funcional. La implantación de un anillo tricuspídeo parece ofrecer los mejores resultados quirúrgicos. En la valvulopatía tricuspídea primaria la sustitución valvular con prótesis biológica o metálica es a menudo necesaria. Ésta se asocia a un alto riesgo quirúrgico, determinado por la alta tasa de reoperaciones y por la disfunción ventricular derecha. En esta revisión abordaremos los métodos ecocardiográficos para la evaluación de la VT, las indicaciones quirúrgicas de la valvulopatía tricuspídea y los resultados de las series publicadas más importantes.

    2010-01-01

    The actual nuclear R and D issues require new technologies and continuous progress in order to find adequate and effective solutions in sustained and increasing energy demand. The current tendency in energy consumption and occurring of large consumers, especially from Asian countries, imposes finding new means for energy clean, large scale and sustained production. NPPs reliability and availability were permanently monitored and improved; in the mean time the safety of the nuclear energy production was under surveillance. Corresponding development of the new technologies and discovery of improved materials and adequate technological processes offers the possibilities for appropriate implementation and use of them in the NPPs systems configuration and functioning/operation. The modern technologies and scientific discoveries, also the international cooperation, offer the opportunities to brake the actual barriers in order to cumulate and use advanced energy production processes in finding new energy sources and to build improved, reliable and safety power plants. The monitoring systems, intelligent sensors and intelligent SSCs, nanotechnologies and and modern and intelligent materials constitute the main reasons in improvement of the NPPs systems configuration and processes. The paper presents: - The state of the art in the level of actual and useful technologies for nuclear power systems development; - The actual technological limits that need to be over passed for NPPs systems improvements; - The main systems that need improvement and reconfiguration for actual NPPs development and increase in efficient operation, appropriate availability and total safety; - The actual energy production issues; - The key arguments in sustaining the R and D new NPPs systems development; - Future trends in NPPs development; - The limitations in industrial processes knowledge and use.

    Full Text Available Before initiating the building operations for the «Palos Verdes» School, the site was divided into two large horizontal surfaces, at different levels. The lower one served to accommodate the playing fields, a car park, the physical training building, and shop and ancillary buildings. On the higher of these two surfaces, and to the West of the access road, there is a car park and also the building and plot of ground devoted to agricultural technology, as well as the literary studies and general purpose buildings. As a complement to these, there is a series of blocks, arranged in parallel rows, which house the administrative offices, the art school, the craft's school, the general classrooms, and those devoted to higher education. The fascinating aspect of this school is the outstanding penetration of the architect's mind into the essential function of the project. Its most evident merit is the sense of comradeship and harmony that permeates the whole architectural manifold.Antes de construir el complejo escolar «Palos Verdes» se comenzó por crear, en el terreno, dos grandes mesetas a niveles diferentes. Sobre el inferior se organizaron: los campos de juegos, de deportes, un aparcamiento, el edificio para educación física y los destinados a tiendas y servicios. Sobre la meseta superior, al oeste de la vía de acceso, se dispuso un aparcamiento y el edificio y campo para adiestramiento agrícola; al este, otro aparcamiento, el edificio dedicado a materias literarias, y el destinado a usos múltiples. Completan las instalaciones de la escuela una serie de bloques paralelos: la administración, la escuela de arte, las clases de trabajos manuales, las aulas de enseñanzas generales, y las de los cursos superiores. Lo fascinante de este complejo escolar es la perfecta y magistral compenetración del arquitecto con el tema proyectado, y su mayor mérito, la sensación de cordialidad y armonía con el ambiente.

    Dancers are highly susceptible to musculoskeletal injuries and frequently require interaction with medical professionals. While many dancers have a finely tuned awareness of their bodies, their knowledge of the fundamentals of human anatomy is not uniform. There is a paucity of literature on the benefits of human anatomy education in dancers, though it seems intuitive that there should be a relationship. The purpose of this study was to assess dancers' perceived and actual knowledge of basic musculoskeletal anatomy and its relationship to function. Adult dancers at the undergraduate, pre-professional, and professional levels were surveyed through an anonymous online questionnaire. Questions included demographic information, dance techniques studied, anatomy training, and injury history. Subjects rated their perceived knowledge of anatomy and were tested with 15 multiple-choice questions on basic musculoskeletal anatomy. Four hundred seventy-five surveys were completed. Ordinal regression showed a correlation of perceived to actual knowledge of anatomy (p < 0.001). Factors that correlated with increases in both perceived and actual knowledge of anatomy included having taken an anatomy course of any type (p < 0.001) and increased age (p ≤ 0.001). Years of dance training and professional dancer status both significantly correlated with increased knowledge of anatomy (p < 0.001) but not perceived knowledge. Chi-square analysis showed that dancers with training in either modern or jazz dance had a significantly higher perceived, but not actual, knowledge when compared to those without training in those styles of dance (p < 0.001 and p = 0.011, respectively). In conclusion, dancers generally scored well on questions pertaining to basic musculoskeletal anatomy, and their perception correlated with their actual knowledge of anatomy. Factors that contribute to dancers' knowledge of anatomy include age, years of experience, professional dancer status, and anatomy training.

  13. Actual imaging time in fetal MRI

    Brugger, Peter C.; Prayer, Daniela

    2012-01-01

    Objective: Safety issues in magnetic resonance imaging (MRI) are important, especially in fetal MRI. However, since basic data with respect of the effective exposure time in fetal MRI are not available, this study aimed to determine the actual imaging time during a fetal MRI study. Methods: 100 fetal MRI studies of singleton pregnancies performed on a 1.5 T system were analysed with respect to study duration (from starting the survey scan until the end of study), the number of sequences acquired, and the actual imaging time, which was calculated by adding up scan time of each sequence. Furthermore, each sequence type was analysed regarding the number of acquisitions, specific absorption rates (SAR), and duration. Results: Mean study duration was 34.6 min (range: 14–58 min; standard deviation (SD): 9.7 min), the average number of sequences acquired was 26.6 (range: 11–44, SD: 6.6). Actual scan time averaged 11.4 min (range: 4–19 min, SD: 4.0 min). Ultrafast T2-weighted and steady-state free-precession sequences accounted for 62.3% of actual scan time, and were distributed over the whole duration of the study. Conclusion: Actual imaging time only accounts for 33% of total study time and is not continuous. The remaining time is consumed by the preparation phases of the scanner, and is spent with planning sequences and the eventual repositioning of the coil and/or pregnant woman. These data may help to more accurately estimate the exposure to radiofrequency deposition and noise during fetal MRI studies.

    Full Text Available The Redwood highway, through the Californian forest, runs on a viaduct, as it crosses a mountain slope of about 45° inclination. The firm ground is fairly deep, and as an additional constructional difficulty, it was necessary to respect the natural beauty of the countryside. A structure of portal frames were built, forming a number of short spans. These spans were bridged with metal girders, on which a 19 m wide deck was placed. The columns are hollow and have a transversal cross beam, to join each pair. There was difficulty in excavating the foundations for the columns, as it was necessary to dig through the soft top soil, and also prevent this soil from hurting the trunks of the forest trees. Another significant difficulty in the construction of this viaduct was the access to the working site, since there were no suitable platforms from which to operate the appropriate machinery. This made it necessary to do a lot of the work by manual operation. As one of the edges of the deck is very close to the mountain side, a supporting beam was erected on this side. It was made of concrete, on metal piles. The formwork for the deck structure was placed on the concrete stems of the supporting piles.La autopista denominada Redwood (California salva, con un paso superior, la ladera de un bosque cuya pendiente es del 1/1.

    To compare the efficacy and safety of Ahmed glaucoma valve (AGV) (New World Medical Inc., Rancho Cucamonga, CA) implantation in the superior versus inferior quadrants. Prospective parallel cohort study. A total of 106 eyes of 106 patients with refractory glaucoma. Consecutive patients with refractory glaucoma underwent AGV implantation in the superior or inferior quadrants. Main outcome measures included intraocular pressure (IOP) and rate of complications. Other outcome measures included best corrected visual acuity (BCVA), number of glaucoma medications, and success rate (defined as at least 30% IOP reduction and 5glaucoma surgery, phthisis bulbi, or loss of light perception. Of a total of 106 eyes, 58 and 48 eyes underwent AGV implantation in the superior and inferior quadrants, respectively. Baseline characteristics were comparable in the study groups, except for preoperative IOP, which was higher in the superior group (P = 0.01). Patients were followed for a mean period of 10.6+/-8.49 months and 10.58+/-6.75 months in the superior and inferior groups, respectively (P = 0.477). BCVA was comparable between the groups at all postoperative visits (P>0.122). After 1 year, statistically significant but comparable IOP reduction from baseline (Pglaucoma medications was comparable after 1 year (1.3+/-1.2 vs. 1.9+/-0.8 for superior and inferior implants, respectively, P = 0.256). Success rates were also similar at 1 year: 27 eyes (81.8%) versus 20 eyes (95.2%) for superior and inferior implants, respectively (P = 0.227). However, the overall rate of complications, such as implant exposure necessitating removal, cosmetically unappealing appearance, and endophthalmitis, was higher in the inferior group: 12 eyes (25%) versus 3 eyes (5.2%) for superior and inferior groups, respectively, (P = 0.004).

  12. Radiation safety actuality in Republic of Moldova

    International Nuclear Information System (INIS)

    Kuharuk, E.S.

    2011-01-01

    Radioecological monitoring issues and radiation safety are actual in the Republic of Moldova. Japan events show us the possibility of natural disasters. Republic of Moldova is surrounded by 8 NPPs, the closest being at the distance of 160 km. Moldovas territory is in seismic zone where underground earthquake shocks reaches 7 points or more. Thatis why radiation safety and radioecological monitoring is actual in our republic. Traces of Chernobyl were left in Moldovas soils. The fallouts of radio nuclides formed on the soil surfaces in the Republic of Moldova following the Chernobyl Nuclear Power Station Accident have been continuously affected by attacks of both natural and technicaly generated agents since the time of fallout. During the past decade a shift in emphasis has taken place regarding the need for more complete and accurate information on reservoir sedimentation. Classical sedimentation surveys involve repeated field measurement and, therefore, this is probably the most costly and time consuming method. The application of radio nuclides, particularly Cs 137, for water erosion and sedimentation studies in Republic of Moldova has not been attempted so far. This paper presents the results obtained on reservoir sedimentation rates in an area subjected to wide range in land degradation dy sheet-rill erosion. The profil characteristics support the assumption that in most undisturbed sites there is a sharp decline in Cs 137 activity with increasing dept. Such an asymmetrical distribution of the Cs 137 would suggest a standard pattern in the form of a cantilever. If the validity of this assamption is accepted it is possible to define two major types of Cs 137 cantilever distribution: shallow and deep buried cantilever. The main criterion in classifying these pattents lies generally in the shape of Cs 137 depth profile and particularly in burial magnitude of Cs 137 peak derived from Chernobyl. Hills area has been impacted by greatest sendimentation. This regional

    This report presents the work that followed the CSSX model development completed in FY2002. The developed cesium and potassium extraction model was based on extraction data obtained from simple aqueous media. It was tested to ensure the validity of the prediction for the cesium extraction from actual waste. Compositions of the actual tank waste were obtained from the Savannah River Site personnel and were used to prepare defined simulants and to predict cesium distribution ratios using the model. It was therefore possible to compare the cesium distribution ratios obtained from the actual waste, the simulant, and the predicted values. It was determined that the predicted values agree with the measured values for the simulants. Predicted values also agreed, with three exceptions, with measured values for the tank wastes. Discrepancies were attributed in part to the uncertainty in the cation/anion balance in the actual waste composition, but likely more so to the uncertainty in the potassium concentration in the waste, given the demonstrated large competing effect of this metal on cesium extraction. It was demonstrated that the upper limit for the potassium concentration in the feed ought to not exceed 0.05 M in order to maintain suitable cesium distribution ratios

    Persistent left superior vena cava absent right superior vena cava is a rare anomaly, with less than 150 cases reported in the literature. Congenitally persistent left superior vena cava is the most common variant of systemic venous return to the heart, resulting embryologically from failure of the left anterior cardinal vein to become obliterated. Its incidence varies from 0.3% in patients with otherwise normal heart to 4.3% in patients with congenital heart disease. In the majority of the patients, a right superior vena cava is present as well, but rarely the right anterior cardinal vein degenerates resulting in the absence of the normal right superior vena cava. The blood from the right side is carried by the persistent left superior vena cava to the right atrium through the coronary sinus. We report the case of a patient with a persistent left superior vena cava and absence of right superior vena cava identified by chance during a chest radiograph and computed tomography examination for investigation of chronic pulmonary obstructive disease. The patient had no congenital heart disease and the blood from the right side was drained by the persistent left superior vena cava into the right atrium through the coronary sinus. (author)

  15. Nanomaterials environmental risks and recycling: Actual issues

    2014-01-01

    Full Text Available Nanotechnologies are being spoken of as the driving force behind a new industrial revolution. Nanoscience has matured significantly during the last decade as it has transitioned from bench top science to applied technology. Presently, nanomaterials are used in a wide variety of commercial products such as electronic components, sports equipment, sun creams and biomedical applications. The size of nanoparticles allows them to interact strongly with biological structures, so they present potential human and environmental health risk. Nanometer size presents also a problem for separation, recovery, and reuse of the particulate matter. Therefore, industrial-scale manufacturing and use of nanomaterials could have strong impact on human health and the environment or the problematic of nanomaterials recycling. The catch-all term ''nanotechnology' is not sufficiently precise for risk governance and risk management purposes. The estimation of possible risks depends on a consideration of the life cycle of the material being produced, which involves understanding the processes and materials used in manufacture, the likely interactions between the product and individuals or the environment during its manufacture and useful life, and the methods used in its eventual disposal. From a risk-control point of view it will be necessary to systematically identify those critical issues, which should be looked at in more detail. Brief review of actual trends in nanomaterials environmental risks and recycling is given in this paper.

  17. The picture superiority effect in associative recognition.

    Hockley, William E

    2008-10-01

    The picture superiority effect has been well documented in tests of item recognition and recall. The present study shows that the picture superiority effect extends to associative recognition. In three experiments, students studied lists consisting of random pairs of concrete words and pairs of line drawings; then they discriminated between intact (old) and rearranged (new) pairs of words and pictures at test. The discrimination advantage for pictures over words was seen in a greater hit rate for intact picture pairs, but there was no difference in the false alarm rates for the two types of stimuli. That is, there was no mirror effect. The same pattern of results was found when the test pairs consisted of the verbal labels of the pictures shown at study (Experiment 4), indicating that the hit rate advantage for picture pairs represents an encoding benefit. The results have implications for theories of the picture superiority effect and models of associative recognition.

  18. Consequences of Predicted or Actual Asteroid Impacts

    Chapman, C. R.

    2003-12-01

    Earth impact by an asteroid could have enormous physical and environmental consequences. Impactors larger than 2 km diameter could be so destructive as to threaten civilization. Since such events greatly exceed any other natural or man-made catastrophe, much extrapolation is necessary just to understand environmental implications (e.g. sudden global cooling, tsunami magnitude, toxic effects). Responses of vital elements of the ecosystem (e.g. agriculture) and of human society to such an impact are conjectural. For instance, response to the Blackout of 2003 was restrained, but response to 9/11 terrorism was arguably exaggerated and dysfunctional; would society be fragile or robust in the face of global catastrophe? Even small impacts, or predictions of impacts (accurate or faulty), could generate disproportionate responses, especially if news media reports are hyped or inaccurate or if responsible entities (e.g. military organizations in regions of conflict) are inadequately aware of the phenomenology of small impacts. Asteroid impact is the one geophysical hazard of high potential consequence with which we, fortunately, have essentially no historical experience. It is thus important that decision makers familiarize themselves with the hazard and that society (perhaps using a formal procedure, like a National Academy of Sciences study) evaluate the priority of addressing the hazard by (a) further telescopic searches for dangerous but still-undiscovered asteroids and (b) development of mitigation strategies (including deflection of an oncoming asteroid and on- Earth civil defense). I exemplify these issues by discussing several representative cases that span the range of parameters. Many of the specific physical consequences of impact involve effects like those of other geophysical disasters (flood, fire, earthquake, etc.), but the psychological and sociological aspects of predicted and actual impacts are distinctive. Standard economic cost/benefit analyses may not

    Full Text Available El objetivo de este ensayo es redimensionar dos elementos de la herencia teórica de R. Hilferding que no se enfatizan mucho en la literatura, aunque son de gran valor teórico y metodológico para el estudio del capitalismo actual. Se trata del análisis de la naturaleza económica de los precios de los monopolios, realizado en "El capital financiero", y a la metodología que aplica el autor en su obra maestra para investigar una nueva etapa en la evolución del capitalismo. La importancia del primer tema es evidente porque vivimos en el mundo donde las grandes corporación transnacionales determinan los precios de sus productos en la medida mucho mayor que lo hacían los cárteles y los trusts del inicio del siglo XX. Y en lo que se refiere al segundo elemento, su actualidad esta dada por el hecho de que, al parecer, de nuevo vivimos en el período de grandes cambios del sistema económico del capitalismo que se manifiestan en: el creciente papel del capital ficticio en la reproducción del capital global; el paso en las políticas económicas de la lógica de Bretton Woods a la de neoconservadurismo y de Consenso de Washington; y, en las modificaciones de la forma y del mecanismo del ciclo económico.

La confianza en que el comercio y la vinculación internacional procuraría el umbral máximo de bienestar a sus poblaciones, impulsó reformas estructurales que desmantelarían el carácter autárquico de sus aparatos productivos; proceso que caló profundamente en Argentina. Pero en este camino, en mayor o menor medida, las economías latinoamericanas no lograron un crecimiento económico sostenido, a pesar de haber recreado sus capacidades productivas y practicado su reestructuración política, salvo algunas economías regionales, o el dinamismo que exhibieron algunas ciudades y comunidades locales. El presente trabajo está dirigido a explorar los elementos que deben ser atendidos a partir de la caracterización del esquema global de producción e intercambio, el cual destaca la relevancia de la actuación de las políticas públicas y la gestión de las ciudades y regiones, espacios dinámicos de la economía global. La búsqueda de competitividad en las ciudades y regiones, como una exigencia de la actual agenda pública, deberá guiar los esfuerzos, por un lado, hacia el desarrollo de competencias en los ambientes locales, y por el otro, al fomento de las exportaciones para ganar competitividad internacional. Se hace presente la relevancia de atender a la construcción de la marca de sus productos, como herramientas para la proyección internacional, y el impulso de las ventas en los mercados externos.

    1988-01-01

    We report the first observation of clinical manifestations of vena cava superior syndrome (VCSS) associated with sarcoidosis. Twenty-four years after the first signs of the disease had been noted, mediastinal lymphomas penetrating the wall of the vena cava superior caused complete obstruction. It is most unusual for the vessel wall to be destroyed in this way, which explains why VCSS is often missed in sarcoidosis. The obstructed vessel was resected and successfully replaced by a Gore-Tex prosthesis. The importance of VCSS for the differential diagnosis is pointed out. Two further peculiarities are the simultaneous occurrence of elevated intraocular pressure and VCSS, and the familial incidence. (orig.) [de

    Full Text Available Although literature advocates the advantages of work force diversification, studies based on the Similarity- Attraction Paradigm indicate that people are more disposed to feel attraction to those who are similar to them. A field study with the comparative data of 89 dyads investigated the effect of the actual and perceived similarity in the quality of the relationship between superiors and subordinates within the Leader-Member Exchange [LMX] perspective. The investigated characteristics were: gender, age and work-family conflict. The data indicate the influence only of perceived similarity in the quality of the relationship between superiors and subordinates. This effect broadens when the subordinate feels satisfied with the quality and frequency of contact with his/her superior. The methodological procedures included factorial analysis and validation of two scales (EIFT and LMX-7, the correlations analysis and hierarchic regressions. Finally, the implications of some results and directions for future research in diversity are discussed.

    Full Text Available Abstract Objective: The objective of this study was to determine the incidence of a "meniscoid" superior labrum. Materials and Methods: This was a retrospective analysis of 582 magnetic resonance imaging examinations of shoulders. Of those 582 examinations, 110 were excluded, for a variety of reasons, and the final analysis therefore included 472 cases. Consensus readings were performed by three musculoskeletal radiologists using specific criteria to diagnose meniscoid labra. Results: A meniscoid superior labrum was identified in 48 (10.2% of the 472 cases evaluated. Arthroscopic proof was available in 21 cases (43.8%. In 10 (47.6% of those 21 cases, the operative report did not include the mention a superior labral tear, thus suggesting the presence of a meniscoid labrum. In only one of those cases were there specific comments about a mobile superior labrum (i.e., meniscoid labrum. In the remaining 11 (52.4%, surgical correlation demonstrated superior labral tears. Conclusion: A meniscoid superior labrum is not an infrequent finding. Depending upon assumptions and the requirement of surgical proof, the prevalence of a meniscoid superior labrum in this study was between 2.1% (surgically proven and 4.8% (projected. However, superior labral tears are just as common and are often confused with meniscoid labra.

    It has been suggested that neurocognitive impairment is a core deficit in schizophrenia. However, it appears that some patients with schizophrenia have intelligence quotients (IQs) in the superior range. In this study, we sought out schizophrenia patients with an estimated premorbid Intelligence Quotient (IQ) of at least 115 and studied their neuropsychological profile. Thirty-four patients meeting diagnostic criteria for schizophrenia or schizoaffective disorder, as defined by the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV), with mean estimated premorbid IQ of 120, were recruited and divided into two subgroups, according to whether or not their IQ had declined by at least 10 points from their premorbid estimate. Their performance on an extensive neuropsychological battery was compared with that of 19 IQ-matched healthy controls and a group of 16 "typical" schizophrenia patients with estimated premorbid IQ Schizophrenia patients whose estimated premorbid and current IQ both lay in the superior range were statistically indistinguishable from IQ-matched healthy controls on all neurocognitive tests. However, their profile of relative performance in subtests was similar to that of typical schizophrenia patients. Patients with superior premorbid IQ and evidence of intellectual deterioration had intermediate scores. Our results confirm the existence of patients meeting DSM-IV diagnostic criteria for schizophrenia who have markedly superior premorbid intellectual level and appear to be free of gross neuropsychological deficits. We discuss the implications of these findings for the primacy of cognitive deficits in schizophrenia.

  9. Perturbation resilience and superiorization of iterative algorithms

    International Nuclear Information System (INIS)

    Censor, Y; Davidi, R; Herman, G T

    2010-01-01

    Iterative algorithms aimed at solving some problems are discussed. For certain problems, such as finding a common point in the intersection of a finite number of convex sets, there often exist iterative algorithms that impose very little demand on computer resources. For other problems, such as finding that point in the intersection at which the value of a given function is optimal, algorithms tend to need more computer memory and longer execution time. A methodology is presented whose aim is to produce automatically for an iterative algorithm of the first kind a 'superiorized version' of it that retains its computational efficiency but nevertheless goes a long way toward solving an optimization problem. This is possible to do if the original algorithm is 'perturbation resilient', which is shown to be the case for various projection algorithms for solving the consistent convex feasibility problem. The superiorized versions of such algorithms use perturbations that steer the process in the direction of a superior feasible point, which is not necessarily optimal, with respect to the given function. After presenting these intuitive ideas in a precise mathematical form, they are illustrated in image reconstruction from projections for two different projection algorithms superiorized for the function whose value is the total variation of the image

    Full Text Available The main characteristics of the land and the supporting rock are given, and the pattern of present performance of Chicago's deep foundations is briefly described. This city probably has some of the highest skyscrapers in the world with deep foundations resting on rock, and possibly as well, the highest building with foundations resting on soil. The construction of piles of large diameter, resting on rock and concreted dry, as prescribed by the City Code, is the weak point which sometimes makes it necessary to insert a permanent lining tube deep into the rock in order to obtain the required leaktightness, or to pump out significant quantities of water from the bottom of the excavations. The latter can cause the dragging away of earth from adjacent foundations resting on soil at a higher level, as with the drift of the phreatic level, with the consequent risk of producing appreciable subsidence, and even undermining. To overcome this problem we carried out for the first time in Chicago, a pre-sealing, by means of chemical injections, of the supporting rock of the periphery piles of some deep foundations, by drilling into the centre of each pile, which has also been useful as a means of examining the subsoil before proceeding to the perforation of each pile. This operation was carried out on the large diameter piles of the foundations of the Northern Trust Bank skyscraper, at present under construction, with very satisfactory results. The method of pre-sealing the rock used and the results obtained are described.Se presentan las características principales del terreno y de la roca de apoyo y se describe someramente la forma de ejecución actual de las cimentaciones profundas de Chicago.

Arteriography is the method of choice even though a diagnosis may be possible by sonography or CT in special cases. Even though an aneurysm of the superior mesenteric artery is rare, it has to be considered in the differential diagnosis of persisting abdominal problems of unknown origin. This is especially true for patients with a predisposing history such as previous or existing endocarditis, sepsis, arteriosclerosis and hypertension. Because of the possibility of rupture followed by life threating bleeding an adequate diagnostic step such as arteriography has to be considered finally.

    2014-01-01

    The majority of individuals evaluate themselves as above average. This is a cognitive bias called "the superiority illusion". This illusory self-evaluation helps us to have hopes for the future, and has been central to the process of human evolution. Possessing this illusion is also important for mental health, as depressed people appear to have a more realistic perception of themselves, dubbed "depressive realism". Our recent study revealed the spontaneous brain activity and central dopaminergic neurotransmission that generate this illusion, using resting-state fMRI and PET. A functional connectivity between the frontal cortex and striatum, regulated by inhibitory dopaminergic neurotransmission, determines individual levels of the superiority illusion. We further revealed that blocking the dopamine transporter, which enhanced the level of dopamine, increased the degree of the superiority illusion. These findings suggest that dopamine acts on striatal dopamine receptors to suppress fronto-striatal functional connectivity, leading to disinhibited, heuristic, approaches to positive self-evaluation. These findings help us to understand how this key aspect of the human mind is biologically determined, and will suggest treatments for depressive symptoms by targeting specific molecules and neural circuits.

  17. Eutrophication monitoring for Lake Superior's Chequamegon ...

    Science.gov (United States)

    A priority for the Lake Superior CSMI was to identify susceptible nearshore eutrophication areas. We developed an integrated sampling design to collect baseline data for Lake Superior’s Chequamegon Bay to understand how nearshore physical processes and tributary loading relate to observed chlorophyll concentrations. Sampling included ship-based water samples combined with vertical CTD casts, continuous in situ towing and data collected from an autonomous underwater glider. Sampling was conducted during June, July and September. The glider collected regional data as part of three extended missions in Lake Superior over the same periods. During the study, two significant storm events impacted the western end of Lake Superior; the first occurred during July 11-12, with 8-10 inches of rain in 24hrs, and the second on July 21 with winds in excess of 161 km/h. Using GIS software, we organized these diverse temporal data sets along a continuous time line with temporally coincident Modis Satellite data to visualize surface sediment plumes in relation to water quality measurements. Preliminary results suggest that both events impacted regional water quality, and that nearshore physical forces (upwelling and currents) influenced the spatial variability. Results comparing in situ measures with remotely sensed images will be discussed. not applicable

    Full Text Available Purpose: We present the first reported case of Waldenstrom macroglobulinemia in the right superior rectus causing diplopia. Observations: A 72-year-old man with a 6-month history of untreated asymptomatic Waldenstrom macroglobulinemia presented with 2 years of diagonal binocular diplopia that was previously thought to be due to ocular myasthenia gravis. Examination showed mild right proptosis and right hypotropia, and MRI revealed a focal lesion of the right superior rectus muscle. Orbital biopsy was performed, and histopathology showed lymphoplasmacytic infiltration among the skeletal muscle fibers of the rectus muscle. Immunostaining confirmed a B-cell preponderance, along with more extensive staining for IgM than IgG, and in situ hybridization confirmed lambda restriction. These findings corresponded with those of his previous bone marrow biopsy, confirming Waldenstrom macroglobulinemia as the etiology for the extraocular muscle mass. Conclusions and Importance: Lymphoma of an extraocular muscle is a rare manifestation of orbital lymphoma, and the tumors are usually mucosa-associated lymphoid tissue (MALT lymphomas (i.e. extranodal marginal zone lymphomas. There are 4 previous reports of lymphoplasmacytic lymphoma of an extraocular muscle; however this is the first reported case of such a lesion in a patient with concurrent Waldenstrom macroglobulinemia at the time of diagnosis.

    2011-12-01

    Full Text Available Superior mesenteric artery syndrome is an entity generally caused by the loss of the intervening mesenteric fat pad, resulting in compression of the third portion of the duodenum by the superior mesenteric artery. This article reports the case of a patient with irremovable metastatic adenocarcinoma in the sigmoid colon, that evolved with intense vomiting. Intestinal transit was carried out, which showed important gastric dilation extended until the third portion of the duodenum, compatible with superior mesenteric artery syndrome. Considering the patient's nutritional condition, the medical team opted for the conservative treatment. Four months after the surgery and conservative measures, the patient did not present vomiting after eating, maintaining previous weight. Superior mesenteric artery syndrome is uncommon and can have unspecific symptoms. Thus, high suspicion is required for the appropriate clinical adjustment. A barium examination is required to make the diagnosis. The treatment can initially require gastric decompression and hydration, besides reversal of weight loss through adequate nutrition. Surgery should be adopted only in case of clinical treatment failure.A síndrome da artéria mesentérica superior é uma entidade clínica causada geralmente pela perda do tecido adiposo mesentérico, resultando na compressão da terceira porção do duodeno pela artéria mesentérica superior.

However, his symptoms did not improve and he was unable to return to his preinjury activity levels, so he sought the services of another physical therapist for a second opinion. Due to concern for a labrum tear, the physical therapist referred the patient to an orthopaedic surgeon. Magnetic resonance arthrography revealed findings consistent with a superior labrum anterior-to-posterior tear.

    Full Text Available Superior vena cava (SVC syndrome is most commonly the insidious result of decreased vascular flow through the SVC due to malignancy, spontaneous thrombus, infections, and iatrogenic etiologies. Clinical suspicion usually leads to computed tomography to confirm the diagnosis. However, when a patient in respiratory distress requires emergent airway management, travel outside the emergency department is not ideal. With the growing implementation of point-of-care ultrasound (POCUS, clinicians may make critical diagnoses rapidly and safely. We present a case of SVC syndrome due to extensive thrombosis of the deep venous system cephalad to the SVC diagnosed by POCUS. [West J Emerg Med. 2014;15(6:715-718

    Full Text Available Superior venacava (SVC thrombus is a condition requiring immediate diagnosis and treatment. SVC thrombus causes obstruction of blood flow through the SVC resulting in severe decrease in venous return from the head, neck and upper extremity to the heart. The presenting symptoms of SVC obstruction include headache, hoarseness of voice, dyspnea, and laryngeal edema, dizziness, swelling of face, neck, and upper extremity. We hereby present a case of SVC thrombus who presented to the casualty department of COMS-TH with features of SVC syndrome which was diagnosed and managed promptly.JCMS Nepal. 2016;12(1:33-5.

    Spontaneous dissection of the superior mesenteric artery (SMA) is a rare occurrence, especially when not associated with aortic dissection. Currently, only 28 cases appear to have been reported. Due to the scarcity of cases in the literature, the natural history of isolated, spontaneous SMA dissection is unclear. CT has been reported to be useful for the initial diagnosis of SMA dissection [2-5]. We present two recent cases of spontaneous SMA dissection in which enhanced spiral CT was instrumental in following the disease process and guiding clinical decision making

    Full Text Available The rapid onset of a bilateral vestibular hypofunction (BVH is often attributed to vestibular ototoxicity. However, without any prior exposure to ototoxins, the idiopathic form of BVH is most common. Although sequential bilateral vestibular neuritis (VN is described as a cause of BVH, clinical evidence for simultaneous and acute onset bilateral VN is unknown. We describe a patient with an acute onset of severe gait ataxia and oscillopsia with features compatible with acute BVH putatively due to a bilateral VN, which we serially evaluated with clinical and laboratory vestibular function testing over the course of 1 year. Initially, bilateral superior and horizontal semicircular canals and bilateral utricles were impaired, consistent with damage to both superior branches of each vestibular nerve. Hearing was spared. Only modest results were obtained following 6 months of vestibular rehabilitation. At a 1-year follow-up, only the utricular function of one side recovered. This case is the first evidence supporting an acute presentation of bilateral VN as a cause for BVH, which would not have been observed without critical assessment of each of the 10 vestibular end organs.

    Full Text Available A veia cava superior é formada pela união das duas veias inominadas, direita e esquerda, e localiza-se no mediastino médio, à direita da artéria aorta e anteriormente à traquéia. A síndrome da veia cava superior representa um conjunto de sinais (dilatação das veias do pescoço, pletora facial, edema de membros superiores, cianose e sintomas (cefaléia, dispnéia, tosse, edema de membro superior, ortopnéia e disfagia decorrentes da obstrução do fluxo sanguíneo através da veia cava superior em direção ao átrio direito. A obstrução pode ser causada por compressão extrínseca, invasão tumoral, trombose ou por dificuldade do retorno venoso ao coração secundária a doenças intra-atriais ou intraluminais. Aproximadamente 73% a 97% dos casos de síndrome da veia cava superior ocorrem durante a evolução de processos malignos intratorácicos. A maioria dos pacientes com a síndrome secundária a neoplasias malignas é tratada sem necessidade de cirurgia, através de radioterapia ou quimioterapia, ou através da colocação de stents endoluminais. Quando a síndrome é de etiologia benigna, o tratamento é feito através de medidas clínicas (anticoagulação, elevação da cabeça, etc. ou, em casos refratários, através de angioplastia, colocação de stents endoluminais e cirurgia.The superior vena cava is formed by the union of the right and left brachiocephalic veins.

    Superior canal dehiscence syndrome (SCDS) is an increasingly recognized cause of hearing loss and vestibular symptoms, but the etiology of this condition remains unknown. To describe 7 cases of SCDS across 3 families. This retrospective case series included 7 patients from 3 different families treated at a neurotology clinic at a tertiary academic medical center from 2010 to 2014. Patients were referred by other otolaryngologists or were self-referred. Each patient demonstrated unilateral or bilateral SCDS or near dehiscence. Clinical evaluation involved body mass index calculation, audiometry, cervical vestibular evoked myogenic potential testing, electrocochleography, and multiplanar computed tomographic (CT) scan of the temporal bones. Zygosity testing was performed on twin siblings. The diagnosis of SCDS was made if bone was absent over the superior semicircular canal on 2 consecutive CT images, in addition to 1 physiologic sign consistent with labyrinthine dehiscence. Near dehiscence was defined as absent bone on only 1 CT image but with symptoms and at least 1 physiologic sign of labyrinthine dehiscence. A total of 7 patients (5 female and 2 male; age range, 8-49 years) from 3 families underwent evaluation. Family A consisted of 3 adult first-degree relatives, of whom 2 were diagnosed with SCDS and 1 with near dehiscence. Family B included a mother and her child, both of whom were diagnosed with unilateral SCDS. Family C consisted of adult monozygotic twins, each of whom was diagnosed with unilateral SCDS. For all cases, dehiscence was located at the arcuate eminence. Obesity alone did not explain the occurrence of SCDS because 5 of the 7 cases had a body mass index (calculated as weight in kilograms divided by height in meters squared) less than 30.0. Superior canal dehiscence syndrome is a rare, often unrecognized condition. This report of 3 multiplex families with SCDS provides evidence in support of a potential genetic contribution to the etiology

    1996-01-01

    The records of 38 patients with superior vena cava syndrome (SVC syndrome) due to malignancy and who received radiation therapy were retrospectively reviewed. The majority were lung cancers, constituting 28 of the 38 cases (73.7%). All patients were treated with conventional radiation doses ranging from 20 to 70 Gy and good symptomatic response was observed in 31 cases (81.6% ). The response appeared within 1.7±0.9 weeks on average (3 days-4 weeks;, and performance status also improved in 50% of the patients. The median survival was 6.6 months. Long term survivors were seen mostly in patients with thymoma, and only one patient ever showed a recurrence of SVC syndrome. We conclude that radiotherapy can be an effective therapeutic modality for SVC syndrome and that it improves the quality of life in most patients. (author)

    The market share between China Mobile and China Unicom has stabilized since 2002.It is found that China Mobile has the superiority in the competition, for example, the scissors movement between its revenue and cost indicates that it has a strong profit generating ability and there is enough room for it to reduce the price.The ratio between its price (marginal income) and marginal cost indicates that there is a very distant limit for it to reduce the price.Its demand is obviously flexible with the price, but it does not use the price weapon abundantly.The reason for the stabilization of the market is that China Mobile withdrew from the competition.

    2009-01-01

    We described three cases of superior mesenteric artery (SMA) syndrome, also known as Wilkie's syndrome, chronic duodenal ileus, or cast syndrome. This syndrome occurs when the third portion of the duodenum is compressed between the SMA and the aorta. The major risk factors for development of SMA syndrome are rapid weight loss and surgical correction of spinal deformities. The clinical presentation of SMA syndrome is variable and nonspecific, including nausea, vomiting, abdominal pain, and weight loss. The diagnosis is based on endoscopic, radiographic and tomographic findings of duodenal compression by the SMA. The treatment of SMA syndrome is aimed at the precipitating factor, which usually is related to weight loss. Therefore, conservative therapy with nutritional supplementation is the initial approach, and surgery is reserved for those who do not respond to nutritional therapy.

    Full Text Available Obstruction of blood flow in the superior vena cava (SVC results in symptoms and signs of SVC syndrome. SVC obstruction can be caused either by invasion or external compression of the SVC by contagious pathologic processes involving the right lung, lymph nodes, and other mediastinal structures, or by thrombosis of blood within the SVC. Occasionally, both mechanisms co-exist. We hereby report a case of a 28-year-old male, Saudi patient who was diagnosed with end-stage renal disease and was maintained on regular hemodiaysis via right jugular vein dual lumen catheter for ten months. Three years later, the patient presented with signs and symptoms suggestive of SVC obstruction that was successfully managed with SVC stenting.

    2002-12-01

    On 4 July 1999, a severe convective windstorm, known as a derecho, caused extensive damage to forested regions along the United States/Canada border, west of Lake Superior. There were 665,000 acres of forest destroyed in the Boundary Waters Canoe Area Wilderness (BWCAW) in Minnesota and Quetico Provincial Park in Canada, with approximately 12.5 million trees blown down. This storm resulted in additional severe weather before and after the occurrence of the derecho, with continuous cloud-to-ground (CG) lightning occurring for more than 34 hours during its path across North America. At the time of the derecho the percentage of positive cloud-to-ground (+CG) lightning measured by the Canadian Lightning Detection Network (CLDN) was greater than 70% for more than three hours, with peak values reaching 97% positive CG lightning. Such high ratios of +CG are rare, and may be useful indicators of severe weather.

    The objectives of this study were to determine whether glenoid inclination (1) could be measured accurately on magnetic resonance imaging (MRI) using computed tomography (CT) as a gold standard, (2) could be measured reliably on MRI, and (3) whether it differed between patients with rotator cuff tears and age-matched controls without evidence of rotator cuff tears or glenohumeral osteoarthritis. In this comparative retrospective radiographic study, we measured glenoid inclination on T1 coronal MRI corrected into the plane of the scapula. We determined accuracy by comparison with CT and inter-rater reliability. We compared glenoid inclination between patients with full-thickness rotator cuff tears and patients aged >50 years without evidence of a rotator cuff tear or glenohumeral arthritis. An a priori power analysis determined adequate power to detect a 2° difference in glenoid inclination. (1) In a validation cohort of 37 patients with MRI and CT, the intraclass correlation coefficient was 0.877, with a mean difference of 0° (95% confidence interval, -1° to 1°). (2) For MRI inclination, the inter-rater intraclass correlation coefficient was 0.911. (3) Superior glenoid inclination was 2° higher (range, 1°-4°, P rotator cuff tear group of 192 patients than in the control cohort of 107 patients. Glenoid inclination can be accurately and reliably measured on MRI. Although superior glenoid inclination is statistically greater in those with rotator cuff tears than in patients of similar age without rotator cuff tears or glenohumeral arthritis, the difference is likely below clinical significance.

    Full Text Available This study is meant to examine the relationships of several antecedents of actual purchase of herbal product in Malaysia. Actual purchase is considered to have a vital link to a business success. The study identified eight antecedents of consumer actual purchase such as intention, attitude, social influence, product safety and culture belief. A total of 473 respondents (about 82% completed and returned the questionnaire. A seven point Likert scale was used to measure responses. The data were analyzed using Partial Least Squares (PLS path modeling. The path coefficient results supported the direct influence of intention, attitude, social influence and product safety on actual buying. Moreover, the findings reveal that attitude, social influence, product safety, and culture belief also influenced buying intention.

    1998-01-01

    The electrodermal response (EDR) of children watching a violent show was measured. Particular attention was paid to the type of violence (actual or implied) that prompted an EDR. In addition, the impact of the auditory component (sounds associated with violence) of the show was evaluated. Implied violent stimuli, such as the villain's face, elicited the strongest EDR. The elements that elicited the weakest responses were the actual violent stimuli, such as stabbing. The background noise and voices of the sound track enhanced the total number of EDRs. The results suggest that implied violence may elicit more fear (as measured by EDRs) than actual violence does and that sounds alone contribute significantly to the emotional response to television violence. One should not, therefore, categorically assume that a show with mostly actual violence evokes less fear than one with mostly implied violence.

    2009-02-01

    To evaluate the effects of liquid nitrogen cryotherapy on superior limbic keratoconjunctivitis (SLK). Interventional case series. In this clinical practice case series, the effects of liquid nitrogen cryotherapy on SLK were observed. Liquid nitrogen cryotherapy was performed using a Brymill E tip spray (0.013-inch aperture) with a double freeze-thaw technique. All subjects were outpatients who had local anesthesia with a single drop of topical proparacaine. The main outcome measure was the resolution of the disease process after treatment. Four female patients (average age, 64 +/- 13 years) and seven eyes with SLK were treated with liquid nitrogen cryotherapy. Resolution of signs and symptoms occurred within two weeks. Disease recurred in two patients and three of seven eyes, although repeat cryotherapy eradicated SLK in all cases. The repeat cryotherapy was performed at three months postoperatively. There were no adverse ocular events. Liquid nitrogen cryotherapy appears to be an effective alternative treatment for SLK as all subjects studied achieved long-term cures. Repeat cryotherapy may be necessary in some instances and may be performed three months after the first treatment.

  13. Lake Superior Coastal Wetland Fish Assemblages and ...

    Science.gov (United States)

    The role of the coastal margin and the watershed context in defining the ecology of even very large lakes is increasingly being recognized and examined. Coastal wetlands are both important contributors to the biodiversity and productivity of large lakes and important mediators of the lake-basin connection. We explored wetland-watershed connections and their relationship to wetland function and condition using data collected from 37 Lake Superior wetlands spanning a substantial geographic and geomorphic gradient. While none of these wetlands are particularly disturbed, there were nevertheless clear relationships between watershed landuse and wetland habitat and biota, and these varied consistently across wetland type categories that reflected the strength of connection to the watershed. For example, water clarity and vegetation structure complexity declined with decreasing percent natural land cover, and these effects were strongest in riverine wetlands (having generally large watersheds and tributary-dominated hydrology) and weakest in lagoon wetlands (having generally small watersheds and lake-dominate hydrology). Fish abundance and species richness both increased with decreasing percent natural land cover while species diversity decreased, and again the effect was strongest in riverine wetlands. Lagoonal wetlands, which lack any substantial tributary, consistently harbored the fewest species of fish and a composition different from the more watershed-lin

    The register of the Dutch social housing stock was analysed, containing 300.000 dwellings, renovated between 2010 and 2013. The main objective was twofold: to evaluate the performance gap in these dwellings before and after the renovation and to establish what renovation measures achieve the highest reduction of consumption, particularly in practice (actual savings). The results showed large performance gaps in dwellings with low R and high U values, local heating systems, changes from a non-condensing into a condensing boiler and upgrades to a natural ventilation system. Regarding the actual effectiveness of renovation measures, replacement of old gas boilers with more efficient ones yields the highest energy reduction, followed by deep improvements of windows. Installing mechanical ventilation yields a small reduction compared to other measures, but still much larger than theoretically expected. The paper shows once more that the calculation method currently in use cannot be considered accurate if compared to actual consumption. The study demonstrated that unrealistic theoretical efficiencies of heating systems and insulation values are causing a part of the performance gap. Nowadays, large datasets of buildings thermal performance and actual consumption offer an opportunity to improve these misconceptions. - Highlights: • Performance gap is lower in more efficient buildings. • Replacements of gas boilers – the most energy reduction among renovation measures. • Replacing the ventilation system yields a much larger reduction than expected. • How well are the standard values of the calculation methods defined? • Provide large public building performance databases including actual use data.

  15. The Business Value of Superior Energy Performance

    Industrial facilities participating in the U.S. Department of Energy’s (US DOE) Superior Energy Performance (SEP) program are finding that it provides them with significant business value. This value starts with the implementation of ISO 50001-Energy management system standard, which provides an internationally-relevant framework for integration of energy management into an organization’s business processes. The resulting structure emphasizes effective use of available data and supports continual improvement of energy performance. International relevance is particularly important for companies with a global presence or trading interests, providing them with access to supporting ISO standards and a growing body of certified companies representing the collective knowledge of communities of practice. This paper examines the business value of SEP, a voluntary program that builds on ISO 50001, inviting industry to demonstrate an even greater commitment through third-party verification of energy performance improvement to a specified level of achievement. Information from 28 facilities that have already achieved SEP certification will illustrate key findings concerning both the value and the challenges from SEP/ISO 50001 implementation. These include the facilities’ experience with implementation, internal and external value of third-party verification of energy performance improvement; attractive payback periods and the importance of SEP tools and guidance. US DOE is working to bring the program to scale, including the Enterprise-Wide Accelerator (SEP for multiple facilities in a company), the Ratepayer-Funded Program Accelerator (supporting tools for utilities and program administrators to include SEP in their program offerings), and expansion of the program to other sectors and industry supply chains.

  16. Physiological models of the lateral superior olive.

    Full Text Available In computational biology, modeling is a fundamental tool for formulating, analyzing and predicting complex phenomena. Most neuron models, however, are designed to reproduce certain small sets of empirical data. Hence their outcome is usually not compatible or comparable with other models or datasets, making it unclear how widely applicable such models are. In this study, we investigate these aspects of modeling, namely credibility and generalizability, with a specific focus on auditory neurons involved in the localization of sound sources. The primary cues for binaural sound localization are comprised of interaural time and level differences (ITD/ILD, which are the timing and intensity differences of the sound waves arriving at the two ears. The lateral superior olive (LSO in the auditory brainstem is one of the locations where such acoustic information is first computed. An LSO neuron receives temporally structured excitatory and inhibitory synaptic inputs that are driven by ipsi- and contralateral sound stimuli, respectively, and changes its spike rate according to binaural acoustic differences. Here we examine seven contemporary models of LSO neurons with different levels of biophysical complexity, from predominantly functional ones ('shot-noise' models to those with more detailed physiological components (variations of integrate-and-fire and Hodgkin-Huxley-type. These models, calibrated to reproduce known monaural and binaural characteristics of LSO, generate largely similar results to each other in simulating ITD and ILD coding. Our comparisons of physiological detail, computational efficiency, predictive performances, and further expandability of the models demonstrate (1 that the simplistic, functional LSO models are suitable for applications where low computational costs and mathematical transparency are needed, (2 that more complex models with detailed membrane potential dynamics are necessary for simulation studies where sub

  18. Exaggerating Accessible Differences: When Gender Stereotypes Overestimate Actual Group Differences.

    Science.gov (United States)

    Eyal, Tal; Epley, Nicholas

    2017-09-01

    Stereotypes are often presumed to exaggerate group differences, but empirical evidence is mixed. We suggest exaggeration is moderated by the accessibility of specific stereotype content. In particular, because the most accessible stereotype contents are attributes perceived to differ between groups, those attributes are most likely to exaggerate actual group differences due to regression to the mean. We tested this hypothesis using a highly accessible gender stereotype: that women are more socially sensitive than men. We confirmed that the most accessible stereotype content involves attributes perceived to differ between groups (pretest), and that these stereotypes contain some accuracy but significantly exaggerate actual gender differences (Experiment 1). We observe less exaggeration when judging less accessible stereotype content (Experiment 2), or when judging individual men and women (Experiment 3). Considering the accessibility of specific stereotype content may explain when stereotypes exaggerate actual group differences and when they do not.

    Full Text Available The present studies address two criticisms of the theory of evolved sex differences in jealousy: (a that the sex difference in jealousy emerges only in response to hypothetical infidelity scenarios, and (b that the sex difference emerges only using forced-choice measures. In two separate studies, one a paper-and-pencil survey with a student sample and the other a web-based survey targeting a non-student sample, men and women showed significant sex differences in jealousy in response to actual infidelity experiences; men experienced more jealousy in response to the sexual aspects of an actual infidelity, whereas women experienced more jealousy in response to the emotional aspects of the infidelity. Sex differences emerged using both continuous measures of jealousy as well as the traditional forced-choice measure. Overall, our results demonstrate that sex differences in jealousy are not limited to responses to hypothetical infidelity scenarios; they also emerge in response to actual infidelity experiences.

    The standard model for cosmology which is now strongly favored is a flat model, dominated by a vacuum density term. However, the actual direct evidences for such term are limited, essentially based on the supernova probe, i.e. based on a standard candle hypothesis. Here I would like to point out that contrary to the general belief there is room for an Einstein de Sitter universe. Actually several independent measurements, not based on stellar reference, pointed towards a high matter density Universe, weakening the need for a cosmological constant

    2014-01-01

    Full Text Available Superior mesenteric artery syndrome is a rare condition that causes a proximal small intestinal obstruction due to contraction of the angle between the superior mesenteric artery and the aorta. Scoliosis surgery is one of the 15 reasons for superior mesenteric artery syndrome, which can present with acute or chronic manifestations. Although conservative treatment is usually possible, surgical treatment is required in certain cases that cannot be treated using conservative methods. In this paper, we describe a patient who developed superior mesenteric artery syndrome after scoliosis surgery and was treated with duodenojejunostomy due to failure and complications of conservative treatment.

    Full Text Available The aim of this study was to know and understand the re-actualization of bale banjar function in Denpasar City. This study was conducted due to the imbalance between the assumptions and current reality. The data sources of this study were some bale banjar-s in Denpasar City, related informants, and previous research findings. All data were collected using observation, interviews, and literature studies techniques and were analyzed using sociocultural evolution, community rationalization, and commodification theories. The research findings showed that re-actualization of bale banjar function in Denpasar City happened due to the high demand of economic space of capitalist economy and the changes of local society’s way of thinking; re-actualization of bale banjar’s form in Denpasar City could be seen from the changes in style and appearance of the spaces that are now widely designed into two floors. The society used the upper floors as a gathering place and the lower floors are rented as a center of economic activity; re-actualization of bale banjar function in Denpasar City had the implications on the way of thinking, the conception of bale banjar form and function and material culture such as the weakening of social relations among krama banjar.

    Full Text Available The Five-Factor Model of personality, which includes dimensions energy, agreeableness, conscientiousness, emotional stability, and openness, gained a growing acceptance by personality researchers. In the present study the actual personality characteristics of physical educators and the personality profile of an ideal (according to subjective evaluations of experts physical educator were investigated. The aim of the study was to examine differences between profiles of actual and preferred personality characteristics and to present differences in personality characteristics between male and female physical educators of different ages. The study included 76 (40 male, 36 female 24 to 58 year-old physical educators (mean age 39.7 years. 34 experts from the field of sport, physical education, and kinesiology evaluated the preferred personality structure of an ideal physical educator. The Big Five Observer (BFO was used to assess actual and preferred personality structures. These results show that the actual personality profile of physical educators is described with all five moderately high dimensions, which is relatively congruent with the social type from Holland's typology, characteristic of educators. In comparison with participants, an ideal physical educator should have equally expressed agreeableness, while other four dimensions should be highly expressed. Gender differences in energy and agreeableness (women have higher results in both dimensions were found significant. No significant age differences in the personality structure were obtained by a cross-sectional comparison.

    2014-02-01

    An examination of actual HIV vaccine trials can contribute to an understanding of motivators for participation in these studies. Analysis of these motivators reveals that they can be categorized as social and personal benefits. Social benefits are generally altruistic, whereas personal benefits are psychological, physical, and financial. In this systematic review, the authors performed a literature search for actual preventive HIV vaccine trials reporting motivators to participation. Of studies conducted in the Organization for Economic Co-operation and Development (OECD) countries, the authors retrieved 12 studies reporting on social benefits and seven reporting on personal benefits. From the non-OECD countries, nine studies reported on social benefits and eight studies on personal benefits. Social benefits were most frequently described on macroscopic, altruistic levels. Personal benefits were most frequently psychological in nature. Rates of participation were compared between the OECD and the non-OECD countries. Knowledge of actual motivators in specific countries and regions can help target recruitment in various types of actual HIV vaccine trials.

  8. Cesium ion exchange using actual waste: Column size considerations

    International Nuclear Information System (INIS)

    Brooks, K.P.

    1996-04-01

    It is presently planned to remove cesium from Hanford tank waste supernates and sludge wash solutions using ion exchange. To support the development of a cesium ion exchange process, laboratory experiments produced column breakthrough curves using wastes simulants in 200 mL columns. To verify the validity of the simulant tests, column runs with actual supernatants are being planned. The purpose of these actual waste tests is two-fold. First, the tests will verify that use of the simulant accurately reflects the equilibrium and rate behavior of the resin compared to actual wastes. Batch tests and column tests will be used to compare equilibrium behaviors and rate behaviors, respectively. Second, the tests will assist in clarifying the negative interactions between the actual waste and the ion exchange resin, which cannot be effectively tested with simulant. Such interactions include organic fouling of the resin and salt precipitation in the column. These effects may affect the shape of the column breakthrough curve. The reduction in column size also may change the shape of the curve, making the individual effects even more difficult to sort out. To simplify the evaluation, the changes due to column size must be either understood or eliminated. This report describes the determination of the column size for actual waste testing that best minimizes the effect of scale-down. This evaluation will provide a theoretical basis for the dimensions of the column. Experimental testing is still required before the final decision can be made. This evaluation will be confined to the study of CS-100 and R-F resins with NCAW simulant and to a limited extent DSSF waste simulant. Only the cesium loading phase has been considered

    Ulrich Teichler

    2006-01-01

    Full Text Available Apoyando la afirmación de que la investigación sobre la educación superior debería buscar más bien explicaciones y hacerlo, además, con una actitud escéptica, el autor argumenta y documenta que, a principios del siglo XXI, la mayoría de europeos están convencidos de que la educación superior se ve mucho más fuertemente afectada que antes por el hecho de hallarse estrechamente incrustada en ambientes europeos y mundiales. En este orden de cosas, el panorama trazado de la situación actual de la educación superior y las políticas relacionadas con la misma en Europa se articula en torno a cinco propuestas de análisis que abundan en aspectos tales como: en las políticas nacionales de educación superior desde hace cincuenta años se ha prestado una atención cada vez mayor a los temas europeos e internacionales pero partir de la década de 1990 las políticas nacionales de este nivel son, al mismo tiempo, políticas europeas e internacionales y las políticas europeas e internacionales de educación superior en Europa son, al mismo tiempo, políticas nacionales. En la actualidad se tiende a configurar un sistema europeo de educación superior en un mundo globalizado aunque las viejas políticas no desaparecen por ello, con lo que las políticas europeas e internacionales de educación superior se vuelven crecientemente complejas. Con todo, la europeización de las políticas de educación superior de los países europeos o de los cuerpos europeos supranacionales en ningún momento contradijeron sustancialmente las políticas internacionales. Finalmente, las políticas de investigación de los países europeos occidentales y de las organizaciones supranacionales activas en Europa siempre fueron impulsadas por otras justificaciones racionales, aparte de las políticas de educación superior.

    Purpose : Authors tried to enhance the safety and accuracy of radiosurgery by verifying stereotactic target point in actual treatment position prior to irradiation. Materials and Methods : Before the actual treatment, several sections of anthropomorphic head phantom were used to create a condition of unknown coordinated of the target point. A film was sand witched between the phantom sections and punctured by sharp needle tip. The tip of the needle represented the target point. The head phantom was fixed to the stereotactic ring and CT scan was done with CT localizer attached to the ring. After the CT scanning, the stereotactic coordinates of the target point were determined. The head phantom was secured to accelerator's treatment couch and the movement of laser isocenter to the stereotactic coordinates determined by CT scanning was performed using target positioner. Accelerator's anteroposterior and lateral portal films were taken using angiographic localizers. The stereotactic coordinates determined by analysis of portal films were compared with the stereotactic coordinates previously determined by CT scanning. Following the correction of discrepancy, the head phantom was irradiated using a stereotactic technique of several arcs. After the irradiation, the film which was sand witched between the phantom sections was developed and the degree of coincidence between the center of the radiation distribution with the target point represented by the hole in the film was measured. In the treatment of actual patients, the way of determining the stereotactic coordinates with CT localizers and angiographic localizers between two sets of coordinates, we proceeded to the irradiation of the actual patient. Results : In the phantom study, the agreement between the center of the radiation distribution and the localized target point was very good. By measuring optical density profiles of the sand witched film along axes that intersected the target point, authors could confirm

    Full Text Available A Síndrome de Deiscência de Canal Semicircular Superior (SDCSS, primeiramente descrita em 1998 por Minor et al., caracteriza-se por vertigem associada à presença de nistagmo, relacionados à exposição a estímulos sonoros intensos ou a modificações de pressão dentro da orelha média ou intracraniana. Disacusia, em sua maioria de padrão condutivo à audiometria tonal, também pode estar presente. Nesta revisão da literatura objetivou-se abordar a SDCSS, com seus principais sinais e sintomas, achados diagnósticos e tratamento, assim como enfatizar a importância de sua inclusão dentre as causas de vertigem, visto tratar-se de acometimento ainda pouco conhecido até mesmo entre especialistas. O diagnóstico correto, além de possibilitar seu tratamento, impede que abordagens diagnósticas e terapêuticas inapropriadas sejam realizadas.The Superior Canal Dehiscence Syndrome (SCDS was first reported by Minor at. Al. (1998, and has been characterized by vertigo and vertical-torsional eye movements related to loud sounds or stimuli that change middle ear or intracranial pressure. Hearing loss, for the most part with conductive patterns on audiometry, may be present in this syndrome. We performed a literature survey in order to to present symptoms, signs, diagnostic and therapeutic approaches to the SCDS, also aiming at stressing the great importance of including this syndrome among the tractable cause of vertigo. We should emphasize that this is a recent issue, still unknown by some specialists. The Correct SCDS diagnosis, besides enabling patient treatment, precludes misdiagnosis and inadequate therapeutic approaches.

    Full Text Available This study reviews the potential of tablet technology for teaching and learning. In autumn 2012, we conducted a focused survey comprising quantitative and qualitative questions with Finnish teachers (N = 171, from 54 schools. We focused on perceived pedagogical opportunities and the actualized pedagogical potential of tablets at schools. The survey results indicate that the actual usefulness of tablets in schools was significantly less than what teachers perceived as the pedagogical potential. However, the results demonstrate the positive impact these devices are having on teaching and learning, as well as prompting changes in pedagogical perspectives. Teachers stated that tablets can diversify and enhance teaching and learning in many ways, particularly in supporting learners’ motivation and independent learning, and promoting engaging teaching methods. Nevertheless, teachers voiced concern that the student-to-device ratio at the moment is too low, thus serving as a barrier to widespread use of tablets.

    The emergence of advanced IT and cloud services has beneficially supported the information-intensive tourism industry, simultaneously caused extreme competitions in attracting customers through building efficient service platforms. On response, numerous nations have implemented cloud platforms to provide value-added sightseeing information and personal intelligent service experiences. Despite these efforts, customers' actual perspectives have yet been sufficiently understood. To bridge the gap, this study attempts to investigate what aspects of tourism cloud services actually delight customers' satisfaction and loyalty. 336 valid survey questionnaire answers were analyzed using structural equation modeling method. The results prove positive impacts of function quality, enjoyment, multiple visual aids, and information quality on customers' satisfaction as well as of enjoyment and satisfaction on use loyalty. The findings hope to provide helpful references of customer use behaviors for enhancing cloud service quality in order to achieve better organizational competitiveness.

    Two types of methods for potential and actual evapotranspiration determining were compared. The first type includes neutron gauge, tensiometers, gypsum blocks and lysimeters. The actual and potential evapotranspiration were calculated by water balance equation. The second type of methods used a simulation model for all calculation. The aim of this study was not only to compare and estimate the methods using. It was mainly pointed on calculations of water use efficiency and transpiration coefficient in potential production situation. This makes possible to choose the best way for water consumption optimization for a given crop. The final results find with the best of the methods could be used for applying the principles of sustainable agriculture in random region of Bulgarian territory. (author)

    PP and L has been monitoring temperatures in the Susquehanna SES reactor building with digital temperature recorders since 1986. In early 1990, data from four representative areas was analyzed to determine the temperature in each area which would produce the same rate of degradation as the distribution of actual temperatures recorded over about 40 months. From these effective average temperatures, qualified life multipliers were determined for activation energies in the range of 0.5 to 1.5 and those multipliers were used to estimate new qualified lives and the number of replacements which might be saved during the life of the plant. The results indicate that pursuing a program of determining EQ qualified lives from actual temperatures, rather than maximum design basis temperatures, will provide a substantial payback in reduced EQ driven maintenance

    Constantinides (1990) describes a simple model of intrinsic habit formation that appears to resolve the "equity premium puzzle" of Mehra and Prescott (1985). This finding is particularly important, since it has motivated a broader consideration of the implications of habit formation preferences in dynamic equilibrium models. However, consumption growth actually behaves very differently pre- and post-1948, and the explanatory power of the habit formation model is driven by the pre-1948 data. U...

    This research describes a new method for the solution of the thermal radiative transfer (TRT) equations that is implicit in time which will be called Actually Implicit Monte Carlo (AIMC). This section aims to introduce the TRT equations, as well as the current workhorse method which is known as Implicit Monte Carlo (IMC). As the name of the method proposed here indicates, IMC is a misnomer in that it is only semi-implicit, which will be shown in this section as well.

    Job satisfaction is essential for physicians' well-being and patient care. The work ethic of long days and hard work that has been advocated for decades is acknowledged as a threat for physicians' job satisfaction, well-being, and patient safety. Our aim was to determine the actual and preferred job size of physicians and to investigate how these and the differences between them influence physicians' job satisfaction. Data were retrieved from a larger, longitudinal study among physicians starting medical training at Groningen University in 1982/83/92/93 (N = 597). Data from 506 participants (85%) were available for this study. We used regression analysis to investigate the influence of job size on physicians' job satisfaction (13 aspects) and ANOVA to examine differences in job satisfaction between physicians wishing to retain, reduce or increase job size. The majority of the respondents (57%) had an actual job size less than 1.0 FTE. More than 80% of all respondents preferred not to work full-time in the future. Respondents' average actual and preferred job sizes were .85 FTE and .81 FTE, respectively. On average, respondents who wished to work less (35% of respondents) preferred a job size reduction of 0.18 FTE and those who wished to work more (12%) preferred an increase in job size of 0.16 FTE. Job size influenced satisfaction with balance work-private hours most (β = -.351). Physicians who preferred larger job sizes were - compared to the other groups of physicians - least satisfied with professional accomplishments. A considerable group of physicians reported a gap between actual and preferred job size. Realizing physicians' preferences as to job size will hardly affect total workforce, but may greatly benefit individual physicians as well as their patients and society. Therefore, it seems time for a shift in work ethic.

    The observed NMR signal size depends on the receiver gain parameter. We propose a receiver gain function to characterize how much the raw FID is amplified by the receiver as a function of the receiver gain setting. Although the receiver is linear for a fixed gain setting, the actual gain of the receiver may differ from what the gain setting suggests. Nevertheless, for a given receiver, we demonstrate that the receiver gain function can be calibrated. Such a calibration enables accurate compar...

    Wong, Voon-Kean; Ho, Jee-Hou; Chai, Ai-Bao

    2017-01-01

    When raindrops impact on the surface of a piezoelectric beam, strain energy produced by the impinging raindrop will be converted to harvestable electrical energy by the piezoelectric layers in a cantilever beam. The novelty of this study is to investigate the performance of the harvester in actual rain and provide practical insights on implementation. The influences of rain parameters such as rain rate, rainfall depth, raindrop count, and drop size distribution (DSD) are discussed in this study. The raindrops accumulated on the surface of the piezoelectric beam will form a water layer. It is described using added mass coefficient in this study. In an actual rain experiment, a piezoelectric beam with surface area of 0.0018 m 2 is able to produce 2076 μJ of energy over a duration of 301 min. The energy generation of a raindrop impact piezoelectric energy harvester is highly dependent on the rain rate. Due to the inconsistency of the energy generation, the piezoelectric energy harvester would require an integration of suitable energy storage device for continuous operation. Nevertheless, this work shows the feasibility of harvesting raindrop energy using a piezoelectric beam. - Highlights: • The performance of a piezoelectric rain energy harvester is tested in actual rain. • The energy generation is highly dependent on the rain rate. • Practical insights on the implementation of the harvester are discussed. • A total energy of 2076 μJ is generated over a duration of 301 min.

  19. "The Actualized Neurosurgeon": A Proposed Model of Surgical Resident Development.

    Science.gov (United States)

    Lipsman, Nir; Khan, Osaama; Kulkarni, Abhaya V

    2017-03-01

    Modern neurosurgical training is both physically and emotionally demanding, posing significant challenges, new and old, to residents as well as programs attempting to train safe, competent surgeons. Models to describe resident development, such as the Accreditation Council for Graduate Medical Education competencies and milestones, address the acquisition of specific skills but largely ignore the stresses and pressures unique to each stage of resident training. We propose an alternative model of resident development adapted from the developmental psychology literature. Our model identifies the challenges that must be met at each stage of junior, intermediate, and senior and chief residency, leading ultimately to an "actualized" neurosurgeon (i.e., one who has maximized his or her potential). Failure to overcome any 1 of these challenges can lead to specific long-lasting consequences, including regret, identity crisis, incompetence, and bitterness. In contrast, the actualized surgeon is one who has successfully acquired the virtues of hope, will, purpose, fidelity, productivity, leadership, competence, and wisdom. The actualized surgeon not only functions safely, confidently, and professionally, but also successfully navigates the challenges of residency and emerges from them having fulfilled his or her maximal potential. This developmental perspective provides an individualized description of healthy surgical development. Our model allows programs to identify the basis for residents who fail to progress, counsel residents during their training, and perhaps help identify resident candidates who are better prepared to meet the developmental challenges of residency training.

    Full Text Available The main goal of the research is to present a way of organising the managerial accounting of totally and semi finished product obtained in chemical fertilizer industry entities. For this study, we analyzed the current principle of managerial accounting to an entity in the studied area, in order to emphasize the need of organizing and implementing a modern accounting management to control the cost and increase the performance of the entities in this area, starting from the premise that there are sufficient similarities between entities in the field. The research has highlighted the fact that, nowadays, the cost calculation is organized using traditional methods, which focus on the monthly determination of the actual unit cost per product (semi-fabric and that it is necessary to organize and implement a managerial accounting, based on the use of a modern method, namely the standard cost method combined with cost centre method. The major implications of the proposed system for the researched field are the monthly calculation of actual costs per cost centres, the calculation of the actual cost per product, as the final cost carrier, to be performed over longer periods of time, usually, quarterly.

  1. The actual citation impact of European oncological research.

    López-Illescas, Carmen; de Moya-Anegón, Félix; Moed, Henk F

    2008-01-01

    This study provides an overview of the research performance of major European countries in the field Oncology, the most important journals in which they published their research articles, and the most important academic institutions publishing them. The analysis was based on Thomson Scientific's Web of Science (WoS) and calculated bibliometric indicators of publication activity and actual citation impact. Studying the time period 2000-2006, it gives an update of earlier studies, but at the same time it expands their methodologies, using a broader definition of the field, calculating indicators of actual citation impact, and analysing new and policy relevant aspects. Findings suggest that the emergence of Asian countries in the field Oncology has displaced European articles more strongly than articles from the USA; that oncologists who have published their articles in important, more general journals or in journals covering other specialties, rather than in their own specialist journals, have generated a relatively high actual citation impact; and that universities from Germany, and--to a lesser extent--those from Italy, the Netherlands, UK, and Sweden, dominate a ranking of European universities based on number of articles in oncology. The outcomes illustrate that different bibliometric methodologies may lead to different outcomes, and that outcomes should be interpreted with care.

    The right superior vena cava draining into the left atrium is a rare malformation causing cyanosis and clubbing in patients in whom no other signs of congenital heart defect are present. Diagnosis may be difficult as cyanosis may be mild and the anomaly is not always easily detectable by echocardiography. For this reason we report a 13-month-old male in whom we confirmed the clinical and echocardiographic suspicion of anomalous drainage of the right superior vena cava using multidetector CT. This allowed successful surgical reconnection of the right superior vena cava to the right atrium. (orig.)

    Nemoto, Kae; Devitt, Simon; Munro, William J.

    2017-06-01

    Quantum information systems are expected to exhibit superiority compared with their classical counterparts. This superiority arises from the quantum coherences present in these quantum systems, which are obviously absent in classical ones. To exploit such quantum coherences, it is essential to control the phase information in the quantum state. The phase is analogue in nature, rather than binary. This makes quantum information technology fundamentally different from our classical digital information technology. In this paper, we analyse error sources and illustrate how these errors must be managed for the system to achieve the required fidelity and a quantum superiority. This article is part of the themed issue 'Quantum technology for the 21st century'.

    Medical students have to process a large amount of information during the first years of their study, which has to be retained over long periods of nonuse. Therefore, it would be beneficial when knowledge is gained in a way that promotes long-term retention. Paper-and-pencil drawings for the uptake of form-function relationships of basic tissues has been a teaching tool for a long time, but now seems to be redundant with virtual microscopy on computer-screens and printers everywhere. Several studies claimed that, apart from learning from pictures, actual drawing of images significantly improved knowledge retention. However, these studies applied only immediate post-tests. We investigated the effects of actual drawing of histological images, using randomized cross-over design and different retention periods. The first part of the study concerned esophageal and tracheal epithelium, with 384 medical and biomedical sciences students randomly assigned to either the drawing or the nondrawing group. For the second part of the study, concerning heart muscle cells, students from the previous drawing group were now assigned to the nondrawing group and vice versa. One, four, and six weeks after the experimental intervention, the students were given a free recall test and a questionnaire or drawing exercise, to determine the amount of knowledge retention. The data from this study showed that knowledge retention was significantly improved in the drawing groups compared with the nondrawing groups, even after four or six weeks. This suggests that actual drawing of histological images can be used as a tool to improve long-term knowledge retention. © 2015 American Association of Anatomists.

    Starting point of the German Mobile Phone Research Project (DMF) were reported health effects from low level exposure. In mostly interdisciplinary projects, these effects were followed up. In addition the actual everyday exposure was evaluated and the risk perception within the society and possibilities for risk communication were investigated. Although there are still scientific questions unsolved, the DMF contributed significantly to an improvement of the risk assessment and the public communication. Overall, the results from DMF and other research projects do not give reason to doubt the effectiveness of the radiation protection limits. (orig.)

    In recent years, many infrastructures have been deteriorating. In order to maintain sustainability of those infrastructures which have significant influence on social lifelines, economical and rational maintenance management should be carried out to evaluate the life cycle cost (LCC). The development of structural health monitoring systems, such as deriving evaluation techniques for the field structural condition of existing structures and identification techniques for the significant engineering properties of new structures, can be considered as the first step in resolving the above problem. New innovative evaluation methods need to be devised to identify the deterioration of infrastructures, e.g. steel tendons, cables in cable-stayed bridges and strands embedded in pre- or post-tensioned concrete structures. One of the possible solutions that show 'AtoE' characteristics, i.e., (a)ccuracy, (b)enefit, (c)ompendiousness, (d)urability and (e)ase of operation, elasto-magnetic (EM) actual stress sensory technology utilizing the sensitivity of incremental magnetic permeability to stress change, has been developed. Numerous verification tests on various steel materials have been conducted. By comparing with load cell, strain gage and other sensory technology measurement results, the actual stresses of steel tendons in a pre-stressed concrete structure at the following stages have been thoroughly investigated: (i) pre-stress change due to set-loss (anchorage slippage) at the tendon fixation stage; (ii) pre-stress change due to the tendon relaxation stage; (iii) concrete creep and shrinkage at the long term pre-stressing stage; (iv) pre-stress change in the cyclic fatigue loading stage; and (v) pre-stress change due to the re-pre-stress setting stage. As the result of this testing, it is confirmed that EM sensory technology enables one to measure actual stress in steel wire, strands and steel bars precisely without destroying the polyethylene covering sheath and enables

    The research presented in this paper is conducted in Ethiopia, which is located in the horn of Africa. Ethiopian economy largely depends on rainfed agriculture, which employs 80% of the labor force. The rainfed agriculture is frequently affected by droughts and dry spells. Small scale irrigation is considered as the lifeline for the livelihoods of smallholder farmers in Ethiopia. Biophysical models are highly used to determine the agricultural production, environmental sustainability, and socio-economic outcomes of small scale irrigation in Ethiopia. However, detailed spatially explicit data is not adequately available to calibrate and validate simulations from biophysical models. The Soil and Water Assessment Tool (SWAT) model was setup using finer resolution spatial and temporal data. The actual evapotranspiration (AET) estimation from the SWAT model was compared with two remotely sensed data, namely the Advanced Very High Resolution Radiometer (AVHRR) and Moderate Resolution Imaging Spectrometer (MODIS). The performance of the monthly satellite data was evaluated with correlation coefficient (R2) over the different land use groups. The result indicated that over the long term and monthly the AVHRR AET captures the pattern of SWAT simulated AET reasonably well, especially on agricultural dominated landscapes. A comparison between SWAT simulated AET and AVHRR AET provided mixed results on grassland dominated landscapes and poor agreement on forest dominated landscapes. Results showed that the AVHRR AET products showed superior agreement with the SWAT simulated AET than MODIS AET. This suggests that remotely sensed products can be used as valuable tool in properly modeling small scale irrigation.

    The field marketing practices of Superior Propane in rural Ontario are illustrated. In the Smithville area, Superior's customer base consists of agricultural, industrial, commercial, and residential customers, plus a large market for auto propane. A 6,900 ft 2 showroom presents a representative selection of the wide range of appliances using propane. Superior's Smithville branch is one of the top five in Canada, in terms of volume. To expand business beyond its traditional branch structures, Superior has an Independent Partners Program which is aimed at all phases of business including independent sales agents, conversions, propane fuel stops, appliance installations, and building contractors. In Keswick, located in the summer resort region on the south shore of Lake Simcoe, Superior's base load is 40% commercial and 20% each agricultural, residential, and automotive. A new 4,100 ft 2 showroom was recently constructed with separate display units for each appliance. The new building has brought increases in auto propane and appliance sales. The different branches of Superior Propane are able to tailor their marketing programs according to local needs by choosing the appropriate programs from those available at head office. 5 figs

  11. Actual conditions of radiation control in radioisotope utilization field

    1980-01-01

    It may be said that the actual conditions on radiation safety are being improved in utilizing radioisotopes or radiation in Japan. It depends greatly on the results of the voluntary effort of users and the regulations by the ''radiation injury prevention law'' and its relevant ordinances. However, the actual conditions of the strict observation of the law are much insufficient. According to the results of official inspection in 1978, 60% of whole enterprises concerned and 73% of educational and medical organizations were judged as incomplete. Such tendency should not be left as it is, but it should also be noticed that there are realities that critical accidents or injuries have not occurred even in such conditions as many violations mentioned above. Since the existing law has not been subjected to essential revision in the past two decades, it might be said that the law does not properly fit to the present conditions because the progress of related techniques was made during this period. Meanwhile, difficulties exist in measuring the low level concentration in the use of low energy radioisotopes or tracer experiments such as in the process analysis in factories or in the analysis of the movement of trace constituent in soil. Further, there is a problem on the necessity of securing the chief technicians handling radiation, and there is the contradiction that the chief technicians are useless in normal condition but are powerless in case of accidents. This situation should be improved as soon as possible. (Wakatsuki, Y.)

    Full Text Available This paper aims at to present the essence and the role of economic education related to the natural movement of a functioning market economy in the Romanian actuality. We understand education as an important form of social consciousness in the sense of bipolarity, namely as the premise and the effect at a dynamic microeconomic and macroeconomic level. In this dynamic movement, economic education appears more and more visibly as a new factor of production or as a new dimension of human capital. In our approach we consider several theoretical and methodological axes that allow us to reveal the interdependence of education to the economic and social development, from an emulative or frantic perspective. In this way we treat the evolution of complex phenomena of economic education in terms of public policy, highlighting the need to intensify the decision-making efforts of management and execution, consistent pursuing to link the causes with the effects of economic education in the Romanian actuality.

    This study proposed a new approach of downscaling ETWATCH 1km actual evapotranspiration (ET) product to a spatial resolution of 30m using land surface resistance that simulated mainly from monthly Landsat8 data and Jarvis method, which combined the benefits of both high temporal resolution of ETWATCH product and fine spatial resolution of Landsat8. The driving factor, surface resistance (Rs), was chosen for the reason that could reflect the transfer ability of vapor flow over canopy. Combined resistance Rs both upon canopy conditions, atmospheric factors and available water content of soil, which remains stable inside one ETWATCH pixel (1km). In this research, we used ETWATCH 1km ten-day actual ET product from April to October in a total of twenty-one images and monthly 30 meters cloud-free NDVI of 2013 (two images from HJ as a substitute due to cloud contamination) combined meteorological indicators for downscaling. A good agreement and correlation were obtained between the downscaled data and three flux sites observation in the middle reach of Heihe basin. The downscaling results show good consistency with the original ETWATCH 1km data both temporal and spatial scale over different land cover types with R2 ranged from 0.8 to 0.98. Besides, downscaled result captured the progression of vegetation transpiration well. This study proved the practicability of new downscaling method in the water resource management.

    2000-10-01

    To assess public attitude, actual working commitment and the respective influence of demographic, psychological and sociological variables on voluntary help in psychiatry. Multiple logistic regression analysis of the results of a representative population survey in Switzerland. Public attitude is mostly positive, but the respective working commitment is small. Attitude depends on gender, psychological factors (social distance, stereotypes), and on attitude to community psychiatry. For the working commitment, clearly distinct predictors are found: age, emotions, participation, and perceived discrimination to the mentally ill. For both attitude and commitment, having a social profession and interest in mass media are predictors. Internationally compared, Switzerland has a positive attitude and a big commitment in lay helping in psychiatry. But attitude is different from actual commitment. Lay helpers' work must be limited to realizable tasks and they need professional recruitment, instruction, and supervision otherwise they tend to be over-burden. The unused potential of voluntary helpers has to be opened specifically, e.g. by involving mass media and opinion-makers.

    Jensen, Anders Fjendbo; Haustein, Sonja; Cherchi, Elisabetta

    , as the EV market is still quite immature in most countries, lack of data on EV users is a common problem for researchers. Data on EV purchase and use have thus often been collected by means of data from intentional statements (see e.g. Bühler et al. 2014), stated preferences (see e.g. Bunch et al. 1993......; Hidrue et al. 2011; Jensen et al. 2014) and EV vehicle trials (Golob & Gould 1998; Franke & Krems 2013; Jensen et al. 2014). While such studies have provided important insight into various areas of the EV market, the fact that the results are not based on actual behaviour means that they are subject...... to a high degree of uncertainty. Being the global EV market forerunner, Norway has a better foundation for studying the EV market based on actual EV owners. On these grounds, Klöckner et al. (2013), studied differences in car use between EV and conventional vehicle (CV) users. Also in Norway, Mersky et al...

  20. Perceived and actual academic competence in maltreated children.

    2001-01-01

    The aims were twofold: 1) to determine whether maltreated and nonmaltreated children differed in the accuracy of their self-assessments of academic achievement; and 2) to determine whether discrepancies between perceived and actual academic competence were related to perceptions of social support from mothers, teachers, and peers. A sample of 195 maltreated children known to a state protective service agency was compared to a control group of 179 nonmaltreated children. The groups were matched on child's gender, age, ethnicity, and birth order; socioeconomic ranking of neighborhood; and family structure. Although maltreated children had significantly lower achievement scores than did nonmal-treated children, the two groups did not differ on perceived academic competence. With regard to discrepancies between perceived and actual competence, maltreated children were more likely than nonmaltreated children to overestimate their level of competence, particularly for reading and arithmetic. Overall, children who reported low maternal support were more likely to overestimate reading competence than were those who reported average or high maternal support. When maltreatment status was considered, maltreated children with low support seemed likely to overestimate abilities, whereas nonmaltreated children with low support seemed likely to underestimate competence. Maltreated children may overestimate their academic abilities in order to compensate for self-perceptions of low self-worth. Efforts to improve academic performance in maltreated children should focus not only on increasing academic skills but also on enhancing self-esteem.

  1. Advanced liquid waste processing technologies: Theoretical versus actual application

    Barker, Tracy A.

    1992-01-01

    This paper provides an overview of Chem-Nuclear Systems, Inc. (CNSI) experience with turn-key chromate removal at the Maine Yankee Nuclear Plant. Theoretical and actual experiences are addressed on topics such as processing duration, laboratory testing, equipment requirements, chromate removal, waste generation, and waste processing. Chromate salts are used in industrial recirculation cooling water systems as a corrosion inhibitor. However, chromates are toxic at concentrations necessary for surface inhibition. As a result, Chem-Nuclear was contracted to perform turn-key chromate removal and waste disposal by demineralization. This project was unique in that prior to on-site mobilization, a composite sample of chromated waste was shipped to CNSI laboratories for treatment through a laboratory scale system. Removal efficiency, process media requirements, and waste processing methodology were determined from this laboratory testing. Samples of the waste resulting from this testing were processed by dewatering and solidification, respectively. TCLP tests were performed on the actual processed waste, and based on the TCLP results, pre-approval for media waste disposal was obtained. (author)

    This paper is a sequel to ''Development of YAG Laser Cladding Technology to Heat Exchanger Flange'' presented in ICONE-8. A YAG Laser cladding technology is a permanent repairing and preventive maintenance method for heat exchanger's flange (channel side) seating surface which is degraded by the corrosion in long term operation. The material of this flange is carbon steel, and that of cladding wire is type 316 stainless steel so as to have high corrosion resistance. In former paper above, the soundness of cladding layers were presented to be verified. This channel side flange is bolted with tube sheet (shell side) through metal gasket. As the tube sheet side is already cladded a corrosion resistant material, it needs to apply the repairing and preventive maintenance method to only channel side. In 2000 this technology had been performed to the actual heat exchanger (Residual Heat Removal Heat Exchanger; RHR Hx) flange in domestic nuclear power plant. This paper described the outline, special equipment, and our total evaluation for this actual laser cladding work. And also several technical subjects which we should solve and/or improve for the next project was presented. (author)

    Full Text Available Ray Kurzweil and others have posited that the confluence of nanotechnology, artificial intelligence, robotics, and genetic engineering will soon produce posthuman beings that will far surpass us in power and intelligence. Just as black holes constitute a ldquo;singularityrdquo; from which no information can escape, posthumans will constitute a ldquo;singularity:rdquo; whose aims and capacities lie beyond our ken. I argue that technological posthumanists, whether wittingly or unwittingly, draw upon the long-standing Christian discourse of ldquo;theosis,rdquo; according to which humans are capable of being God or god-like. From St. Paul and Luther to Hegel and Kurzweil, the idea of human self-deification plays a prominent role. Hegel in particular emphasizes that God becomes wholly actualized only in the process by which humanity achieves absolute consciousness. Kurzweil agrees that God becomes fully actual only through historical processes that illuminate and thus transform the entire universe. The difference is that for Kurzweil and many other posthumanists, our offspringmdash;the posthumansmdash;will carry out this extraordinary process. What will happen to Home sapiens in the meantime is a daunting question.br /br /

    We surveyed the actual conditions of mammography with regard to image quality and radiation dose at 44 facilities in Kagoshima prefecture in 1999. In April 2004, guidelines for mammography newly included the standard of digital mammography. From September to October 2005, the survey was conducted at 48 facilities, and the results of the survey were compared with that in 1999. We visited 44 of the 48 facilities, and visually evaluated the image quality of mammograms for RMI156 and clinical mammograms. In addition, we measured average mammary gland dose at each facility. The number of the mammography device that satisfied the specified guideline criterion was larger than that in 1999. Image quality for the RMI156 mammograms improved. However, the results of the present survey revealed several problems. First, the number of facilities that had quality control instruments for mammography are few. Second, radiological technologists, medical doctors, and nurses did not share knowledge or information regarding mammography. Finally, there were differences in devices and image quality for mammography among the facilities. We achieved an understanding of the actual conditions of mammography in Kagoshima prefecture by visiting many facilities, evaluating image quality, and communicating with many staff members. Our results may be useful for the development of mammography examinations. (author)

  6. Fatigue life prediction of autofrettage tubes using actual material behaviour

    International Nuclear Information System (INIS)

    Jahed, Hamid; Farshi, Behrooz; Hosseini, Mohammad

    2006-01-01

    There is a profound Bauschinger effect in the behaviour of high-strength steels used in autofrettaged tubes. This has led to development of methods capable of considering experimentally obtained (actual) material behaviour in residual stress calculations. The extension of these methods to life calculations is presented here. To estimate the life of autofrettaged tubes with a longitudinal surface crack emanating from the bore more accurately, instead of using idealized models, the experimental loading-unloading stress-strain behaviour is employed. The resulting stresses are then used to calculate stress intensity factors by the weight function method as input to fatigue life determination. Fatigue lives obtained using the actual material behaviour are then compared with the results of frequently used ideal models including those considering Bauschinger effect factors and strain hardening in unloading. Using standard fatigue crack growth relationships, life of the vessel is then calculated based on recommended initial and final crack length. It is shown that the life gain due to autofrettage above 70% overstrain is considerable

    The impact of context on perception has been well documented for over a century. In some cases, the introduction of context to a set of target features may produce a unified percept, leading to a quicker and more accurate classification; a configural superiority effect (Pomerantz, Sager, & Stoever, 1977). Although this effect has been well characterized in terms of the stimulus features that produce the effect, the specific impact context has on the spatial strategies adopted by observers when making perceptual judgments remains unclear. Here, we sought to address this question by using the methods of response classification and ideal observer analysis. In our main experiment, we used a stimulus set known to produce the configural superiority effect and found that although observers were faster in the presence of context, they were actually less efficient at extracting stimulus information. This surprising result was attributable to the use of a spatial strategy in which observers relied on redundant, noninformative features in the presence of context. A control experiment ruled out the possibility that the mere presence of added context led to these strategic shifts. Our results support previous notions about the nature of the perceptual shifts that are induced by the configural superiority effect. However, they also show that configural processing is more nuanced than originally thought: Although observers may be faster at making judgments when context induces the percept of a configural whole, there appears to be a hidden cost in terms of the efficiency with which information is used.

    Full Text Available Superior semicircular canal dehiscence syndrome was first reported by Lloyd Minor and colleagues in 1998. Patients with a dehiscence in the bone overlying the superior semicircular canal experience symptoms of pressure or sound-induced vertigo, bone conduction hyperacusis, and pulsatile tinnitus. The initial series of patients were diagnosed based on common symptoms, a physical examination finding of eye movements in the plane of the superior semicircular canal when ear canal pressure or loud tones were applied to the ear, and high-resolution computed tomography imaging demonstrating a dehiscence in the bone over the superior semicircular canal. Research productivity directed at understanding better methods for diagnosing and treating this condition has substantially increased over the last two decades. We now have a sound understanding of the pathophysiology of third mobile window syndromes, higher resolution imaging protocols, and several sensitive and specific diagnostic tests. Furthermore, we have a treatment (surgical occlusion of the superior semicircular canal that has demonstrated efficacy. This review will highlight some of the fundamental insights gained in SCDS, propose diagnostic criteria, and discuss future research directions.

    Prediction of energy production is crucial to the design and installation of the building integrated photovoltaic systems. This prediction should be attainable based on the commonly available parameters such as system size, orientation and tilt angle. Several commercially available as well as free downloadable software tools exist to predict energy production. Six software models have been evaluated in this study and they are: PV Watts, PVsyst, MAUI, Clean Power Estimator, Solar Advisor Model (SAM) and RETScreen. This evaluation has been done by comparing the monthly, seasonaly and annually predicted data with the actual, field data obtained over a year period on a large number of residential PV systems ranging between 2 and 3 kWdc. All the systems are located in Arizona, within the Phoenix metropolitan area which lies at latitude 33° North, and longitude 112 West, and are all connected to the electrical grid.

    The degree to which consumers expect foods to satisfy hunger, referred to as expected satiation, has been reported to predict food intake. Yet this relationship has not been established precisely, at a quantitative level. We sought to explore this relationship in detail by determining whether expected satiation predicts the actual intake of semi-solid desserts. Two separate experiments were performed: the first used variations of a given food (eight apple purées), while the second involved a panel of different foods within a given category (eight desserts). Both experiments studied the consumption of two products assigned to volunteers based on their individual liking and expected satiation ratings, given ad libitum at the end of a standardised meal. A linear model was used to find predictors of food intake and included expected satiation scores, palatability scores, BMI, age, sex, TFEQ-R, TFEQ-D, water consumption during the meal, reported frequency of eating desserts, and reported frequency of consuming tested products as explanatory variables. Expected satiation was a significant predictor of actual food intake in both experiments (apple purée: F(1,97) = 18.60, P desserts: F(1,106) = 9.05, P desserts, on group and on individual level. Our results confirm the importance of expected satiation as a predictor of subsequent food intake, but highlight the need to study individual consumption behaviour and preferences in order to fully understand the role of expected satiation.

    2016-12-01

    Full Text Available Background: In modern linguistics E. Sepir’s-B. Warf’s theory of a language relativity attracts attention of many scientists, the essence of which some linguists negate as well as they don’t agree to a traditional system of the methodological bases of linguoculturology because this theory «approves» linguonationalism. Purpose: The purpose of the analysis is to illustrate the fact of implementation of the linguonationalism ideology concerning the Ukrainian language by the Russian Empire; the very fact is observed nowadays and the linguopatriotism of the Ukrainians is negated and disrespected by the Russian linguists. Results: Linguonationalism is the ideologization of the very language and a language as a means of a collective self-identification, as a realization of a certain language policy of totalitarian states and modelling of myths in different language forms (discourses. The status of the Ukrainian language, its functions, ontology in Ukraine is considered by modern Russian linguists untruthfully, certain facts are falsified. The system of O. Potebnya’s views represents the objective points of view on the actualized in this research notions of «linguonationalism» and «linguopatriotism». O. Potebnya singled out the task to keep to a reasonable linguopatriotism, which is mentioned in his quotation: «a gradual nationalism – is internationalism». O. Potebnya emphasizes that a nation can be understood only through its language. It is the language that gives the opportunity to see and to feel a nation’s seeing of the world. The scientist actualizes the problem of a modern culturology and the language must be considered as «a certain means of creation and thought refining». Discussion: Modern Ukrainian linguists must elaborate a certain perspective programme aimed at the explanation of the problem of linguonationalism and linguopatriotism.

  2. Noise management to achieve superiority in quantum information systems.

    Quantum information systems are expected to exhibit superiority compared with their classical counterparts. This superiority arises from the quantum coherences present in these quantum systems, which are obviously absent in classical ones. To exploit such quantum coherences, it is essential to control the phase information in the quantum state. The phase is analogue in nature, rather than binary. This makes quantum information technology fundamentally different from our classical digital information technology. In this paper, we analyse error sources and illustrate how these errors must be managed for the system to achieve the required fidelity and a quantum superiority.This article is part of the themed issue 'Quantum technology for the 21st century'. © 2017 The Author(s).

    Anthropogenic climate change has the potential to alter many facets of Earth's freshwater resources, especially lacustrine ecosystems. The effects of anthropogenic changes in Lake Superior, which is Earth's largest freshwater lake by area, are not well documented (spatially or temporally) and predicted future states in response to climate change vary. Here we show that Lake Superior experienced a slow, steady increase in production throughout the Holocene using (paleo)productivity proxies in lacustrine sediments to reconstruct past changes in primary production. Furthermore, data from the last century indicate a rapid increase in primary production, which we attribute to increasing surface water temperatures and longer seasonal stratification related to longer ice-free periods in Lake Superior due to anthropogenic climate warming. These observations demonstrate that anthropogenic effects have become a prominent influence on one of Earth's largest, most pristine lacustrine ecosystems.

    Full Text Available Pyomyositis is a primary bacterial infection of striated muscles nearly always caused by Staphylococcus aureus. Development of the intramuscular abscess involving the extra-ocular muscles (EOMs remains an extremely rare process. We herein present a case of isolated EOM pyomyositis involving superior rectus muscle in a 2-year male child who was referred with complaints of swelling in left eye (LE and inability to open LE since last 1-month. Orbital computed tomography (CT scan showed a well-defined, hypo-dense, peripheral rim-enhancing lesion in relation to left superior rectus muscle suggestive of left superior rectus abscess. The abscess was drained through skin approach. We concluded that pyomyositis of EOM should be considered in any patient presenting with acute onset of orbital inflammation and characteristic CT or magnetic resonance imaging features. Management consists of incision and drainage coupled with antibiotic therapy.

    1982-01-01

    One recurrent theme in the literature on aging and memory is that the decline of memory for nonverbal information is steeper than for verbal information. This research compares verbal and visual encoding using the picture superiority effect, the finding that pictures are remembered better than words. In the first experiment, an interaction was found between age and type of material; younger subjects recalled more pictures than words while older subjects did not. However, the overall effect was small and two further experiments were conducted. In both of these experiments, the picture superiority effect was found in both age groups with no interaction. In addition, performing a semantic orienting task had no effect on recall. The finding of a picture superiority effect in older subjects indicates that nonverbal codes can be effectively used by subjects in all age groups to facilitate memory performance.

    2014-01-01

    Full Text Available Importance. Superior semicircular canal dehiscence (SCD is a third window lesion of the inner ear causing symptoms of vertigo, autophony, tinnitus, and hearing loss. A “two-hit” hypothesis has traditionally been proposed, whereby thinly developed bone overlying the superior canal is disrupted by a sudden change in intracranial pressure. Although the symptoms of SCD may be precipitated by head injury, no previous reports have described a temporal bone fracture directly causing SCD. Observations. Two patients sustained temporal bone fractures after closed head trauma, and developed unilateral otologic symptoms consistent with SCD. In each instance, computed tomography imaging revealed fractures extending through the bony roof of the superior semicircular canal. Conclusions and Relevance. Temporal bone fractures, which are largely treated nonoperatively, have not previously been reported to cause SCD. As it is a potentially treatable entity, SCD resulting from temporal bone fracture must be recognized as a possibility and diagnosed promptly if present.

    2004-01-01

    The shortjaw cisco (Coregonus zenithicus) was historically found in Lakes Huron, Michigan, and Superior, but has been extirpated in Lakes Huron and Michigan apparently as the result of commercial overharvest. During 1999-2001, we conducted an assessment of shortjaw cisco abundance in five areas, spanning the U.S. waters of Lake Superior, and compared our results with the abundance measured at those areas in 1921-1922. The shortjaw cisco was found at four of the five areas sampled, but abundances were so low that they were not significantly different from zero. In the four areas where shortjaw ciscoes were found, abundance declined significantly by 99% from the 1920s to the present. To increase populations of this once economically and ecologically important species in Lake Superior, an interagency rehabilitation effort is needed. Population monitoring is recommended to assess population trends and to evaluate success of rehabilitation efforts.

    Full Text Available There is a tight relationship between information assurance, the intelligence cycle and information superiority within NATO operations. The intelligence cycle has a discrete architecture and provides on-time and relevant intelligence products to the joint force commanders and to other authorized users in a specifi c joint area of operations. The intelligence cycle must follow the evolution of the operation. A permanent intelligence estimate will be performed during the military decision making process and operations execution. Information superiority is one of the most powerful intelligence cycle achievements. and decisively infuences the success of NATO joint operations. Information superiority must be preserved and enhanced through information assurance. Information assurance is an information operation that must be planned by the military in charge of operation security or by non-military experts, executed by all personnel during the entire intelligence cycle life time and employed during the planning and execution of NATO joint operations.

    Full Text Available Data suggests that individuals with schizophrenia (SZ and superior intelligence can present without specific neurocognitive deficits. However, neurocognitive decrements, defined as worse cognition than expected, have been reported in practically all schizophrenia cases. This study investigated if neurocognitive decrements are present in intellectually superior SZ by comparing the neuropsychological profile of SZ cases with IQ-matched healthy controls (HC across intellectual level. Participants with SZ and HCs were stratified into three IQ-groups; intellectually low (IQ 80-95; SZ n = 65 & HC n = 13, intellectually normal (IQ = 100-115; SZ n = 111 & HC n = 115 and intellectually superior (IQ > 120; SZ n = 20 & HC n = 50. A repeated measures multivariate analysis of co-variance compared performance on eight selected neuropsychological tests across IQ-strata and diagnostic group. Differences in clinical characteristics and social functioning in SZ across IQ-strata were investigated with multivariate and univariate analyses of variance. Intellectually superior SZ participants scored within normal limits, but had neurocognitive decrements compared to superior HCs. Decrements were of the same magnitude as in the low and normal IQ-strata. Levels of functional impairments and clinical characteristics in participants with SZ did not differ significantly across IQ-strata. Results indicate that neurocognitive decrements are present in intellectually superior SZ to the same extent as in intellectually low and intellectually normal SZ, supporting the notion that SZ is a neurocognitive disorder. Similar levels of social functional deficits and clinical symptoms suggest similar disease processes in SZ across intellectual level.

In image reconstruction, the problem can be ill-posed and also contaminated by noise; due to this, approaches such as regularization should be utilized. Total variation (TV) is a useful regularization penalty, frequently utilized in image reconstruction for generating images with sharp edges. When a non-quadratic norm is selected for regularization, as is the case for TV, then it is no longer possible to use CG. Non-linear CG is an alternative, but it does not share the efficiency that CG shows with least squares and methods such as fast iterative shrinkage-thresholding algorithms (FISTA) are preferred for problems with TV norm. A different approach to including prior information is superiorization. In this paper it is shown that the conjugate gradient method can be superiorized. Five different CG variants are proposed, including preconditioned CG. The CG methods superiorized by the total variation norm are presented and their performance in image reconstruction is demonstrated. It is illustrated that some of the proposed variants of the superiorized CG method can produce reconstructions of superior quality to those produced by FISTA and in less computational time, due to the speed of the original CG for least squares problems. In the Appendix we examine the behavior of one of the superiorized CG methods (we call it S-CG); one of its input parameters is a positive number ɛ. It is proved that, for any given ɛ that is greater than the half-squared-residual for the least squares solution, S-CG terminates in a finite number of steps with an output for which the half-squared-residual is less than or equal to ɛ. Importantly, it is also the case that the output will have a lower value of TV than what would be provided by unsuperiorized CG for the same value ɛ of the half-squared residual.

    Bottom trawling by the U. S. Fish and Wildlife Service motor vessel Cisco in Lake Superior in 1952–1953 revealed a large population of a tiny whitefish, Coregonus (Prosopium) coulteri, which has been reported previously only from northwestern North America. The hiatus in range, from Lake Superior to the Columbia River basin, is the greatest known for a North American freshwater fish. Although minor structural differences characterize the disjunct populations of the pygmy whitefish, these are not deemed worthy of nomenclatorial recognition. Comparisons with related species indicate that the pygmy whitefish is distinctive in the small size, large scales, few vertebrae, few pyloric caeca, and in other characters.

    Pseudoaneurysm of the superior gluteal artery (SGA) is very rare and the most common causes are blunt or penetrating pelvic traumas. Although pseudoaneurysm can be asymptomatic at the time of initial trauma, it can be symptomatic weeks, months, even years after initial trauma. We present a case of a ruptured superior gluteal artery pseudoaneurysm with hemorrhagic shock twenty days after a bomb injury in the Syria civil war. In addition, we review the anatomy of the SGA, clinical presentation and pitfalls of pseudoaneurysm, and imaging and treatment options.

  15. Designing Pareto-superior demand-response rate options

    We explore three voluntary service options-real-time pricing, time-of-use pricing, and curtailable/interruptible service-that a local distribution company might offer its customers in order to encourage them to alter their electricity usage in response to changes in the electricity-spot-market price. These options are simple and practical, and make minimal information demands. We show that each of the options is Pareto-superior ex ante, in that it benefits both the participants and the company offering it, while not affecting the non-participants. The options are shown to be Pareto-superior ex post as well, except under certain exceptional circumstances. (author)

    Hippocampal sclerosis is the most common cause of drug-resistant epilepsy amenable for surgical treatment and seizure control. The rationale of the selective amygdalohippocampectomy is to spare cerebral tissue not included in the seizure generator. Describe the selective amygdalohippocampectomy through the trans-superior temporal gyrus keyhole approach. Selective amygdalohippocampectomy for temporal lobe epilepsy is performed when the data (semiology, neuroimaging, electroencephalography) point to the mesial temporal structures. The trans-superior temporal gyrus keyhole approach is a minimally invasive and safe technique that allows disconnection of the temporal stem and resection of temporomesial structures.

En el paradigma de pensador danés encontramos en la estructura del ser personal la necesidad de relacionarse con Dios, pasando por distintos estadios de la vida desde un primer estadio inferior “estético” a otro estadio superior “ético-religioso”. En la visión del filósofo alemán, por su parte, situamos la esencia del ser humano en la vivencia instintiva de la inmediatez propia de la exaltación de la vida sin límite y de la búsqueda del placer autonomizado, vivencias que al final se vuelven contra la vida misma.

A história relata que no século XVIII a sífilis e a tuberculose eram responsáveis por 40% dos casos conhecidos. O conhecimento das alterações hemodinâmicas compreendidas nesta síndrome assim como a apuração das técnicas de diagnóstico de imagem e de citopatologia permitem hoje que o médico possa tratar de seu paciente com mais segurança e conforto do que há 10 anos. A TC contrastada e a RM auxiliam no diagnóstico de localização da obstrução e técnicas mais antigas como a cavografia puderam ser abandonadas. O diagnóstico de obstrução da VCS e o estudo por Doppler realizado à beira do leito em muito contribuem para a realização de procedimentos de desobstrução como a angioplastia transluminal percutânea nos casos de trombose ou estenose do vaso. Também a utilização de próteses como PTFE é de importância fundamental na condução de casos de lesão traumática da VCS durante cirurgias para câncer pulmonar ou mediastinal. No campo da radioterapia, a técnica de fracionamento permite que altas doses de irradiação sejam administradas aos pacientes portadores de neoplasias malignas, com benefícios em 70% dos casos.Lung cancer is now the main cause of blood flow obstruction in the superior vena cava and of its clinical manifestations.

  19. The Cinematic Bergson: From Virtual Image to Actual Gesture

    Full Text Available Deleuze’s film-philosophy makes much of the notion of virtual images in Bergson’s Matter and Memory, but in doing so he transforms a psycho-meta-physical thesis into a (very unBergsonian ontological one. In this essay, we will offer a corrective by exploring Bergson’s own explanation of the image as an “attitude of the body”—something that projects an actual, corporeal, and postural approach, not only to cinema, but also to philosophy. Indeed, just as Renoir famously said that “a director makes only one movie in his life. Then he breaks it into pieces and makes it again,” so Bergson wrote that each philosopher only makes one “single point” throughout his or her whole career. And this one point, he then declares, is like a “vanishing image,” only one best understood as an attitude of the body. It is embodied image that underlies an alternative Bergsonian cinema of the actual and the body—one that we will examine through what Bergson’s has to say about “attitude” as well as “gesture” and “mime.” We will also look at it through a gestural concept enacted by a film, to be precise, the five remakes that comprise Lars von Trier’s and Jørgen Leth’s The Five Obstructions (2003. This will bring us back to the idea of what it is that is being remade, both by directors and philosophers, in Renoir’s “one film” and Bergson’s singular “vanishing image” respectively.  Is the “one” being remade an image understood as a representation, or is it a gesture, understood as a bodily movement? It is the latter stance that provides a wholly new and alternative view of Bergson’s philosophy of cinema.

    ENGLISH ABSTRACT: To develop high quality products, a designer has to consider various influential factors, one of which is ergonomics. And to fashion a specific product for the user, a designer needs expert knowledge of the user’s requirements. However, expert knowledge can also be accessed through an intelligent advisory system for ergonomic design support. The effectiveness of such an expert system depends mainly on the quality of the knowledge base and on the appropriateness of the system's inference engine. Data for the system’s knowledge base can be collected in different ways. One approach is to study relevant projects to collect appropriate ergonomic solutions; another is to recognise bottlenecks in ergonomic design. This paper presents a case study of the design of an actual chainsaw – with emphasis on ergonomic design solutions – that can be transformed into ergonomic design recommendations. At the end of the paper, an application of one of the derived recommendations within the knowledge base of the intelligent advisory system is presented.

    Actual molecular strategies in therapy of lymphoma attempt to utilize the immune system to target and eliminate residual lymphoma cells after first line therapy. Therefore lymphoma-specific vaccines are used. Therapy was already successful in vitro, in vivo studies are planned for the near future. In the past two decades, prognosis of lymphoma patients has improved due to advances in staging as well as in therapy control. The introduction of duplex sonography allows the decision on dignity of suspicious lymph nodes not only by size criteria but also by different perfusion pattern. Similar advances have been made in cross sectional imaging like computed tomography and magnetic resonance imaging. The development of lymph node specific contrast agents present new tools for further investigation. In nuclear medicine, functional imaging using positron-emission tomography presents new perspectives especially in diagnosis and treatment control of malignant lymphoma. The visualization of the glucose metabolism using the radiolabeled glucose analogue fluorodeoxyglucose (FDG) allows the detection of involved lymph nodes independent of arbitrary criteria such as lesion diameter. First studies on the use of FDG-PET in staging and restaging of lymphoma patients show promising results. (orig.) [de

    In the framework of the ESA-funded project "GOCE High-level Processing Facility", an operational hardware and software system for the scientific processing (Level 1B to Level 2) of GOCE data has been set up by the European GOCE Gravity Consortium EGG-C. One key component of this software system is the processing of a spherical harmonic Earth's gravity field model and the corresponding full variance-covariance matrix from the precise GOCE orbit and calibrated and corrected satellite gravity gradiometry (SGG) data. In the framework of the time-wise approach a combination of several processing strategies for the optimum exploitation of the information content of the GOCE data has been set up: The Quick-Look Gravity Field Analysis is applied to derive a fast diagnosis of the GOCE system performance and to monitor the quality of the input data. In the Core Solver processing a rigorous high-precision solution of the very large normal equation systems is derived by applying parallel processing techniques on a PC cluster. Before the availability of real GOCE data, by means of a realistic numerical case study, which is based on the actual GOCE orbit and mission scenario and simulation data stemming from the most recent ESA end-to-end simulation, the expected GOCE gravity field performance is evaluated. Results from this simulation as well as recently developed features of the software system are presented. Additionally some aspects on data combination with complementary data sources are addressed.

    Full Text Available Although the Republic of South Africa telecommunications market is a maturing one with a large customer base to serve, it has been repeatedly been observed over the past few years that many good intentions were formulated in the regulatory sphere with sometimes poor outcomes and unclear governance. A number of surprising observations have been made on the outcomes, the delays or other process related events linked to regulatory measures. The paper thus researches first, from a governance point of view, who is actually regulating the telecommunications industry; it identifies next opportunities and bottlenecks whereby a change might happen to reach the expected outcomes. A political economy methodology is taken, backed up by extensive field work over 2010 and 2011, leading to a web of conjectures providing answers to the first question, based on an extensive analysis of key stakeholders goals, positions and interactions. Finally, a number of measures are proposed to improve the governance, regulatory impact and efficiency, and evolve the South African telecommunications eco-system.

  11. Reconciling actual and perceived rates of predation by domestic cats

    2015-01-01

    The predation of wildlife by domestic cats (Felis catus) is a complex problem: Cats are popular companion animals in modern society but are also acknowledged predators of birds, herpetofauna, invertebrates, and small mammals. A comprehensive understanding of this conservation issue demands an understanding of both the ecological consequence of owning a domestic cat and the attitudes of cat owners. Here, we determine whether cat owners are aware of the predatory behavior of their cats, using data collected from 86 cats in two UK villages. We examine whether the amount of prey their cat returns influences the attitudes of 45 cat owners toward the broader issue of domestic cat predation. We also contribute to the wider understanding of physiological, spatial, and behavioral drivers of prey returns among cats. We find an association between actual prey returns and owner predictions at the coarse scale of predatory/nonpredatory behavior, but no correlation between the observed and predicted prey-return rates among predatory cats. Cat owners generally disagreed with the statement that cats are harmful to wildlife, and disfavored all mitigation options apart from neutering. These attitudes were uncorrelated with the predatory behavior of their cats. Cat owners failed to perceive the magnitude of their cats’ impacts on wildlife and were not influenced by ecological information. Management options for the mitigation of cat predation appear unlikely to work if they focus on “predation awareness” campaigns or restrictions of cat freedom. PMID:26306163

    2001-10-01

    This study analyzed 271 actual police cases in order to address several prevalent issues in the eyewitness literature. Suspect identification (SI) rates were obtained for 289 photographic lineups, 258 field showups, 58 live lineups, and 66 lineup identifications preceded by earlier identifications. SI rates were assessed for 3 levels of extrinsic evidence: no extrinsic evidence, evidence of minimal probative value, and evidence of substantial probative value. The SI rates for the photographic lineups were assessed as a function of delay, same vs. cross-race conditions, witness type, and weapon presence. SI rates declined significantly over time; SI rates were significantly greater for the same-race condition. SI rates were much greater for field showups than photographic lineups, 76% vs. 48%. The SI rates for the field showups did not vary as a function of eyewitness conditions. The relation between confidence and suspect/foil identifications for the live lineups was significant and moderately high. The utility of archival identification studies for eyewitness testimony research is discussed.

    Full Text Available Seeking funds to finance the war against the Turks which it entered in July 1876, Serbia, ruled by Prince Milan Obrenović, passed the decision on issuing paper banknotes with no backing in precious metals. They were printed at the national printing house in Belgrade. About 1500 pieces of banknotes of the Main National Treasury of the Principality of Serbia were printed in different denominations: 1, 5, 10, 50, and 100 dinars. These banknotes were never actually in circulation, being the test prints only, used to check whether the machines and technology for their future printing were working properly. They are extremely rare and popular with collectors. The most interesting ones are the 1-dinar banknotes because they have no reverse side, the 5-dinar banknotes because they were painted by the poet and painter Đura Jakšić, and the 10-dinar ones because they feature the drawings of the painter Đorđe Krstić.

  15. How to actualize potential: a bioecological approach to talent development.

    Science.gov (United States)

    Ceci, Stephen J; Williams-Ceci, Sterling; Williams, Wendy M

    2016-08-01

    Bioecological theory posits three interacting principles to explain developmental outcomes such as fluctuating achievement levels and changing heritability coefficients. Here, we apply the theory to the domain of talent development, by reviewing short-term and long-term cognitive interventions. We argue that macro-level analyses of cultural practices (e.g., matrilineal inheritance and property ownership) and national systems of education are consistent with the bioecological theory; when the findings from these analyses are unpacked, the engines that drive them are so-called proximal processes. This finding has implications for the design and delivery of instruction and the development of talent. We argue that talent is fostered by the same three bioecological mechanisms that explain the actualization of genetic potential. We conclude by discussing several self-descriptions and personal narratives by gifted students in which they spontaneously refer to these bioecological mechanisms in their own talent-development processes. Similar testimonials have been documented by historic talent researchers such as Benjamin Bloom, noting the importance of continual adjustments in feedback. © 2016 New York Academy of Sciences.

    Full Text Available Aim: The superior gluteal nerve may be compromised during hip surgery. We retrospectively evaluated the patients who underwent proximal femoral nailing for unstable trochanteric fractures in order to investigate the presence of superior gluteal nerve injury and its clinical findings. Material and Method: Twenty five patients (14 women, 11 men were included in the study who had femoral nailing between January 2004 and March 2010 at Hamidiye Sisli Etfal Training and Research Hospital Department of Orthopaedics. Two different types of nails which have similar designs and surgical techniques were used for fracture fixation. Patients who had a history of cerebrovascular disease, electromyography findings of polyneuropathy, or degenerative vertebral disease were excluded from the study. Patients were evaluated clinically and radiologically. Findings related to acute denervation in the gluteus medius muscle and motor unit action potential changes were accepted as signs of superior gluteal nerve injury. Results: Eight patients were using support during walking and three of these patients had positive Trendelenburg sign, but only one patient had acute denervation signs of the superior gluteal nerve. Discussion: Based on the present study the incidence of iatrogenic nerve injury is a rare complication of proximal femoral nailing. Elderly patients, regardless of whether they have nerve injury, may limp and need to use a walking support.

    1995-01-01

    Over the last 5 years, refining companies have not performed well financially, generating returns below the cost of capital. Environmental regulations have caused the industry to invest significant amounts of capital, and while new regulations will cause the shutdown of between 500 thousand and 1.2 million barrels per day of capacity, the industry structure will remain poor and financial returns for the average player will likely be volatile, cyclical, and below the cost of capital. Based on this industry outlook, refining companies seeking superior performance will have to break the traditional paradigms and adopt world-class practices used in other industries. Changes required to significantly improve financial returns will include shifts in business strategy to accommodate growth, and development of nontraditional services, as well as initiates to dramatically reshape cost structure and improve profitability. Making the changes to become a superior performer in the refining business will require a clear vision and strong leadership at multiple levels in the organization. The transformation will also require changes in company culture and incentive plans that encourage managers to act as owners. In addition, superior performers will push accountability for results to low levels in the organization. Given the herd mentality of the oil industry, superior performers must take decisive, preemptive action to generate a substantial, competitive advantage

    To establish the surgical results and residual symptoms in 48 cases with unilateral congenital superior oblique muscle palsy that had surgical intervention to the vertical muscles alone. Myectomy and concomitant disinsertion of the inferior oblique (IO) muscle was performed in 38 cases and myectomy and concomitant IO disinsertion and recession of the superior rectus muscle in the ipsilateral eye was performed in 10 cases. The preoperative and postoperative vertical deviation values and surgical results were compared. Of the patients who had myectomy and concomitant IO disinsertion, 74% achieved an "excellent" result, 21% a "good" result, and 5% a "poor" result postoperatively. The difference in deviation between preoperative and postoperative values was statistically significant (P < .001). Of the patients who had myectomy and concomitant inferior oblique disinsertion and ipsilateral superior rectus recession, 50% achieved an "excellent" result, 20% a "good" result, and 30% a "poor" result postoperatively. The difference in deviation between preoperative and postoperative values was statistically significant (P < .001). Both procedures are effective and successful in patients with superior oblique muscle palsy, but a secondary surgery may be required. Copyright 2012, SLACK Incorporated.

    artículo, tuvo el objetivo de discutir las indicaciones, la técnica, las complicaciones y los motivos por los cuales algunos autores han refutado la eficacia de la mencionada técnica. CONTENIDO: Han sido revisadas las indicaciones, la técnica y las complicaciones de la maniobra de compresión del cartílago cricoides. También se analizaron los aspectos que han hecho con que algunos autores abandonen la maniobra de Sellick durante la inducción anestésica con la técnica de secuencia rápida. CONCLUSIONES: La aplicación de la maniobra de compresión del cartílago cricoides exige el conocimiento de la anatomía de la vía aérea superior y de la fuerza correcta a ser empleada. Estudios endoscópicos y radiológicos, como también pacientes que presentaron aspiración pulmonar pese al uso de la maniobra de Sellick, han colocado en tela de juicio la utilidad de la técnica. Además de eso, cuando se usa mal, puede causar deformidad de ese cartílago, el cierre de las cuerdas vocales y dificultad de ventilación. A pesar del papel de destaque representado por la maniobra de Sellick en la prevención de la aspiración pulmonar, no se garantiza la protección de las vías aéreas para todos los pacientes, principalmente cuando la técnica no está correctamente aplicada.BACKGROUND AND OBJECTIVES: Sellick described the importance of applying pressure in the cricoid cartilage during anesthesia induction to prevent regurgitation of gastric contents. Since then, the maneuver has been widely accepted by anesthesiologists as a fundamental step during induction with the rapid sequence technique. The objective of the present report was to discuss the indications, technique, complications, and reasons why some authors have refuted the efficacy of this technique. CONTENTS: The indications, technique, and complications of compression of the cricoid cartilage were reviewed. The aspects that have motivated some authors to abandon the Sellick maneuver during anesthetic induction

    Full Text Available El principal objetivo del proceso de convergencia de la enseñanza superior que estamos viviendo, en el marco del Espacio Europeo de Educación Superior (EEES, es convertir a los sistemas universitarios europeos en un referente internacional por la calidad de la enseñanza impartida. Ello exige una revisión, actualización y adaptación de las actuales metodologías docentes y de su organización, así como del establecimiento de técnicas y prácticas que permitan evaluar integralmente la enseñanza. En este contexto, el presente trabajo se analizan los tres pilares de la evaluación de la educación superior: en primer lugar, la evaluación del alumnado (o del aprendizaje según las diferentes formas alternativas de evaluación de los resultados de los alumnos, en segundo lugar, la evaluación de la actividad docente, analizando las ventajas e inconvenientes de las encuestas de opinión, y por último la evaluación institucional de la docencia

    Full Text Available La convulsión financiera iniciada en octubre de 2008 ha reavivado el debate político, social y doctrinal sobre las debilidades del sistema monetario y financiero internacional. Desde su consolidación institucional en la segunda post-guerra mundial, su legitimidad,eficiencia y justicia se han cuestionado constantemente. En estos últimos meses, su incapacidad para prever y evitar crisis como la actual se ha criticado especialmente. La crisis de la deuda de los años ochenta, el “tequilazo” mexicano de 1994 o la crisisasiática de finales de los años noventa ponen de manifiesto la existencia de elementos que dichas instituciones no han sido capaces de controlar. La cadena de infortunios financieros de los últimos meses lo corrobora y hace necesaria una profunda reflexión en términos económicos, jurídicos y también institucionales.El Fondo Monetario Internacional constituye, junto con el Banco Internacional de Reconstrucción y Fomento, el núcleo del sistema monetario y financiero internacional. Creado por los acuerdos de Bretton Woods en diciembre de 1945, el Fondo debía encargarse en su origen de favorecer la estabilidad financiera y el crecimiento económico de los Estados, poniendo a disposición de éstos sus recursos. Con el paso de los años, su cometido se ha ampliado abarcando cada vez más aspectos como la supervisión de las políticas económicas de los países miembros o la influencia en las políticas macroeconómicas nacionales. Esa extensión de sus facultades va unida, sin lugar a duda, a una creciente responsabilidad por el cumplimiento satisfactorio de su misión.Teniendo esto en cuenta, el actual debate sobre la necesidad de una nueva arquitectura financiera internacional debe ahondar en las fortalezas y debilidades del Fondo, por su papel fundamental en la misma. En este sentido, la reforma iniciada en 2005 bajo ladirección del español Rodrigo Rato se ha enfrentado a la evaluación más exigente: una crisis

    Full Text Available Se hace una revisión sobre las hipótesis actuales concernientes a la sensibilidad dentinal, centrando el análisis en las teorías acerca de la presencia de nervios en la dentina, la transmisión del impulso nervioso mediante el odontoblasto y el movimiento de fluidos dentro de la dentina. Por ser la explicación de la sensibilidad de la dentina uno de los más complejos problemas de la fisiología y la histología del diente, se exponen los hechos morfológicos y funcionales que apoyan la validez de los mecanismos mencionados. Se concluye que aunque la teoría hidrodinámica tiene una sólida base experimental y es la de mayor aceptación en la actualidad, pudieran estar involucrados en la génesis del dolor dentinal más de una de estas explicaciones probables.A review of the present hypotheses of dentinal sensitivity was carried out. The analysis was centered on the theories of the existance of nerves in dentin, the transfer of nervous impulse through odontoblast and the fluid flow in the dentin. Since the explanation of dentin sensitivity is one of the most complex problems of dental physiology and histology; the morphological and functional aspects that support the validity of the mentioned mechanisms are stated. It is concluded that although the hydrodynamic theory has a sound experimental basis and is widely accepted at present, more than one of these likely theories could be involved in the genesis of dentinal pain.

    Full Text Available The article presents the overview of linguistic research on gastronomic / gluttony communicative environment as ethnocultural phenomenon from the standpoint of conceptology, discourse study and linguosemiotics. The authors study the linguosemiotic encoding / decoding in the English gastronomic (gluttony discourse. The peculiarities of gastronomic gluttonyms "immersion" into everyday communication are studied. The anglophone ethnicities are revealed and different ways of gluttony texts (including the precedent ones formation are investigated. The linguosemiotic parameters of ethnocultural (anglophone gastronomic coded communication are established, their discursive characteristics are identified. It is determined that in English gastronomic communication, the discursive actualization of ethno-linguocultural code has a dynamic nature; the constitutive features of gastronomic discourse have symbolic (semiotic basics and are connected with such semiotic categories as code, encoding, decoding. It was found that food is semiotic in its origin and represents the cultural code. It was revealed that the semiosis of English gastronomic text is regularly filled with the codes of traditional "English-likeness" (ethnic term by Roland Barthes expressed by gluttonyms. "Nationality" code is detected through the names of products specific to certain areas; national identity of ethnic code also allows highlighting ways of dish garnishing and serving, typical characteristics of particular local preparation methods. The authors analyze the "lingualization" of food images having an ambivalent character, determined, firstly, by food signs (gluttonyms which structure the common space of gastronomic discourse and provide it with ethnic linguocultural food source; secondly, by immerging formed images into a specific ethnic code that is decoded in gastronomic discourse unfolding. The precedent texts accumulate ethnic information supplying adequate gastronomic worldview

    Aim: To examine the association between superior semicircular canal dehiscence (SSCD) and pulsatile tinnitus (PT). Materials and methods: Two SSCD groups included 408 unilateral persistent PT patients, and 511 controls undergoing head and neck dual-phase contrast-enhanced computed tomography (DP-CECT) for reasons other than PT. The prevalence of type I (no the superior petrosal sinus running through the dehiscence) and type II (superior semicircular canal dehiscence in relation to the superior petrosal sinus) SSCD was analysed using chi-square test. Results: SSCD was identified in 5.1% (21/408) of PT ears, significantly different from 2% (8/408) of non-PT ears and 0.7% (7/1022) of controls. There was no significant difference in SSCD prevalence between non-PT ears in the PT group and controls. In the PT group, 15/21 ears were type II SSCD; 6/21 ears were type I. Fifteen combined non-PT and control ears with SSCD included two type II and 13 type I SSCD. The prevalence of type II SSCD in PT ears was significantly higher than that of non-PT ears in both groups, and the prevalence of type I SSCD in PT ears was similar to that of non-PT ears in both groups. Conclusion: Compared with type I SSCD, there may be a causal relationship between type II SSCD and PT. -- Highlights: •The prevalence of type II SSCD in PT ears was significantly higher than that in non-PT ears in both the PT group and controls. •The prevalence of type I SSCD was similar among the PT ears and non-PT ears. •The superior petrosal sinus running through the dehiscence may be essential for SSCD to induce PT. •Venous phase CT images with bone window settings is the modality method to differentiate type II from type I SSCD

  20. The Penokean orogeny in the Lake Superior region

    Schulz, K.J.; Cannon, W.F.

    2007-01-01

    The Penokean orogeny began at about 1880 Ma when an oceanic arc, now the Pembine-Wausau terrane, collided with the southern margin of the Archean Superior craton marking the end of a period of south-directed subduction. The docking of the buoyant craton to the arc resulted in a subduction jump to the south and development of back-arc extension both in the initial arc and adjacent craton margin to the north. A belt of volcanogenic massive sulfide deposits formed in the extending back-arc rift within the arc. Synchronous extension and subsidence of the Superior craton resulted in a broad shallow sea characterized by volcanic grabens (Menominee Group in northern Michigan). The classic Lake Superior banded iron-formations, including those in the Marquette, Gogebic, Mesabi and Gunflint Iron Ranges, formed in that sea. The newly established subduction zone caused continued arc volcanism until about 1850 Ma when a fragment of Archean crust, now the basement of the Marshfield terrane, arrived at the subduction zone. The convergence of Archean blocks of the Superior and Marshfield cratons resulted in the major contractional phase of the Penokean orogeny. Rocks of the Pembine-Wausau arc were thrust northward onto the Superior craton causing subsidence of a foreland basin in which sedimentation began at about 1850 Ma in the south (Baraga Group rocks) and 1835 Ma in the north (Rove and Virginia Formations). A thick succession of arc-derived turbidites constitutes most of the foreland basin-fill along with lesser volcanic rocks. In the southern fold and thrust belt tectonic thickening resulted in high-grade metamorphism of the sediments by 1830 Ma. At this same time, a suite of post-tectonic plutons intruded the deformed sedimentary sequence and accreted arc terranes marking the end of the Penokean orogeny. The Penokean orogen was strongly overprinted by younger tectonic and thermal events, some of which were previously ascribed to the Penokean. Principal among these was a

    Proximal or 'downhill' esophageal varices are a rare cause of upper gastrointestinal hemorrhage. Unlike the much more common distal esophageal varices, which are most commonly a result of portal hypertension, downhill esophageal varices result from vascular obstruction of the superior vena cava (SVC). While SVC obstruction is most commonly secondary to malignant causes, our review of the literature suggests that benign causes of SVC obstruction are the most common cause actual bleeding from downhill varices. Given the alternative pathophysiology of downhill varices, they require a unique approach to management. Variceal band ligation may be used to temporize acute variceal bleeding, and should be applied on the proximal end of the varix. Relief of the underlying SVC obstruction is the cornerstone of definitive treatment of downhill varices. A young woman with a benign superior vena cava stenosis due to a tunneled internal jugular vein dialysis catheter presented with hematemesis and melena. Urgent upper endoscopy revealed multiple 'downhill' esophageal varices with stigmata of recent hemorrhage. As there was no active bleeding, no endoscopic intervention was performed. CT angiography demonstrated stenosis of the SVC surrounding the distal tip of her indwelling hemodialysis catheter. The patient underwent balloon angioplasty of the stenotic SVC segment with resolution of her bleeding and clinical stabilization. Downhill esophageal varices are a distinct entity from the more common distal esophageal varices. Endoscopic therapies have a role in temporizing active variceal bleeding, but relief of the underlying SVC obstruction is the cornerstone of treatment and should be pursued as rapidly as possible. It is unknown why benign, as opposed to malignant, causes of SVC obstruction result in bleeding from downhill varices at such a high rate, despite being a less common etiology of SVC obstruction.

Varios estudios han demostrado factores de riesgo laborales asociados a ideación suicida y altos índices de suicidio en el personal sanitario con respecto a la población general. Objetivos: Describir la situación actual del suicidio en el personal sanitario y evaluar las características demográficas, factores laborales relacionados con ideación suicida y tendencias de acuerdo a la localización geográfica y además compararlas con la población general u otras profesiones. Método: Revisión bibliográfica en diferentes bases de datos, en dos fases: búsqueda/selección de artículos y evaluación de 20 estudios seleccionados. Resultados: El personal sanitario tiene mayor riesgo de suicidio comparado con la población general y otras profesiones. Se evidenció mayor riesgo en los sectores de enfermería, farmacéutico, odontología y medicina. Las especialidades médicas con mayor riesgo son anestesiología y psiquiatría. La tasa de suicidio es mayor en mujeres. Se objetiva mayor riesgo en grupos de mayor edad. En cuanto los métodos más utilizados en EEUU son las armas de fuego, mientras que en otros países es la sobredosis de drogas. Las experiencias desagradables recientes/acoso laboral, el burnout y conflictos laborales han demostrado ser factores de riesgo en la ideación suicida en médicos. Conclusiones: Existen diferencias demográficas en las características del suicidio de acuerdo a diferentes poblaciones estudiadas. Los métodos empleados en médicos por países son diferentes, que posiblemente se deban a la influencia cultural de cada país. Se han encontrado factores asociados entre riesgo e ideación suicida. Sería importante trabajar en ellos para elaborar estrategias de prevención en esta población.

    Home is considered the preferred place of death for many, but patients with haematological malignancies (leukaemias, lymphomas and myeloma) die in hospital more often than those with other cancers and the reasons for this are not wholly understood. We examined preferred and actual place of death among people with these diseases. The study is embedded within an established population-based cohort of patients with haematological malignancies. All patients diagnosed at two of the largest hospitals in the study area between May 2005 and April 2008 with acute myeloid leukaemia, diffuse large B-cell lymphoma or myeloma, who died before May 2010 were included. Data were obtained from medical records and routine linkage to national death records. 323 deceased patients were included. A total of 142 (44%) had discussed their preferred place of death; 45.8% wanted to die at home, 28.2% in hospital, 16.9% in a hospice, 5.6% in a nursing home and 3.5% were undecided; 63.4% of these died in their preferred place. Compared to patients with evidence of a discussion, those without were twice as likely to have died within a month of diagnosis (14.8% vs 29.8%). Overall, 240 patients died in hospital; those without a discussion were significantly more likely to die in hospital than those who had (p≤0.0001). Of those dying in hospital, 90% and 75.8% received haematology clinical input in the 30 and 7 days before death, respectively, and 40.8% died in haematology areas. Many patients discussed their preferred place of death, but a substantial proportion did not and hospital deaths were common in this latter group. There is scope to improve practice, particularly among those dying soon after diagnosis. We found evidence that some people opted to die in hospital; the extent to which this compares with other cancers is of interest. Published by the BMJ Publishing Group Limited.

    Full Text Available El asma bronquial es una de las enfermedades a las que más se enfrenta el médico cubano, y un mejor conocimiento de su fisiopatología ha provocado modificaciones en la estrategia terapéutica. Con el propósito de actualizar conocimientos referentes al tema de los antiinflamatorios esteroides y el uso de los dispositivos para la terapia inhalatoria, se realizó una revisión bibliográfica, para lo cual se consultó la información disponible en Medline, Medscape, Infomed y Doyma; se realizó además un bosquejo sobre la evolución fisiopatológica del asma y su repercusión en la terapéutica actual; se resumieron los aspectos más importantes de la terapia por vía inhalatoria, los dispositivos empleados para este fin, así como las drogas más usadas; y se concluyó que son fundamentales en el tratamiento del asma y que deben ser usados precozmente en todo asmático crónico, que los efectos adversos son mínimos usados adecuadamente, y que es de importancia capital el uso correcto de esos inhaladores.Bronchial asthma is one of the diseases that is more commonly faced by the Cuban physician, so a better knowledge of its physiopathology has brought about changes in the therapeutic strategy. With the objective of updating knowledge about steroid anti-inflammatory drugs and the use of devices for inhaling therapy, a literature review was made using data available in Medline, Medscape, Infomed and Doyma. This was accompanied by an outline of the physiopathological evolution of asthma and its effect on the present therapy. The most important aspects of inhaling therapy, the devices used as well as the most used drugs were summarized and it was concluded that inhalers are fundamental in asthma treatment, that they should be early used in chronic asthma cases, their adverse effects are minimal if adequately applied and that the correct use of these devices are of vital importance.

  9. [The institutionalization of health care in Russia: actual trends].

    Since XX century, health care is a first-rate social institution. The analysis of tendencies of functioning of institution of health care in modern Russia is presented by the article in methodological plane of the system of social structural functions (AGIL) proposed by T. Parsons. The patient is the main participant of medical organizational process. The activity of other participants of process of organization of medical care is to be focused primarily on satisfaction of needs of patient during medical care rendering. The society implements training of subjects for executing their professional roles that determines professionalization of executed functions. The most important purpose of modern training programs in medical education is determined by leading level of cognition, forecasting and achievement of socially significant aftermaths of future during structuring of educational process. In the context of integrative function the coordination of activities of participants of interaction is implemented. In conditions of actual tendencies of market economy the interaction of participants of the process of medical care rendering and the process of quality control of medical care is developed on the basis of implementation of standards of medical care. In Russia, the institutionalization of health care presupposes cooperation and interaction of subjects of system differing by degree and amount of collaborative work. The latent function (maintenance of value pattern) determines regularity, predictability, stability of functioning of social relationships. The social control supports expedient behavior of participants of process of medical care rendering. The dysfunctional practices of modern Russian health care are considered in the context of concept of effective interaction of participants of medical organizational process targeted to maintenance of rights of patients for accessible and qualitative medical care. As a result of applied analysis, the problems were

     Downscaling is one of the important ways of utilizing the combined benefits of the high temporal resolution of Moderate Resolution Imaging Spectroradiometer (MODIS) images and fine spatial resolution of Landsat images. We have evaluated the output regression with intercept method and developed the Linear with Zero Intercept (LinZI) method for downscaling MODIS-based monthly actual evapotranspiration (AET) maps to the Landsat-scale monthly AET maps for the Colorado River Basin for 2010. We used the 8-day MODIS land surface temperature product (MOD11A2) and 328 cloud-free Landsat images for computing AET maps and downscaling. The regression with intercept method does have limitations in downscaling if the slope and intercept are computed over a large area. A good agreement was obtained between downscaled monthly AET using the LinZI method and the eddy covariance measurements from seven flux sites within the Colorado River Basin. The mean bias ranged from −16 mm (underestimation) to 22 mm (overestimation) per month, and the coefficient of determination varied from 0.52 to 0.88. Some discrepancies between measured and downscaled monthly AET at two flux sites were found to be due to the prevailing flux footprint. A reasonable comparison was also obtained between downscaled monthly AET using LinZI method and the gridded FLUXNET dataset. The downscaled monthly AET nicely captured the temporal variation in sampled land cover classes. The proposed LinZI method can be used at finer temporal resolution (such as 8 days) with further evaluation. The proposed downscaling method will be very useful in advancing the application of remotely sensed images in water resources planning and management.

  12. Tullio phenomenon in superior semicircular canal dehiscence syndrome.

    2014-03-18

    Tullio phenomenon refers to eye movements induced by sound.(1) This unusual examination finding may be seen in superior semicircular canal dehiscence (SSCD) syndrome.(2) This disorder is due to absent bone over the superior semicircular canal (figure). Patients complain of dizziness triggered by loud sound, aural fullness, autophony, and pulsatile tinnitus. When Tullio phenomenon exists in SSCD syndrome, the patient develops a mixed vertical-torsional nystagmus in which the slow phase rotates up and away from the affected ear (video on the Neurology® Web site at Neurology.org). This pattern of nystagmus aligns in the plane of the dehiscent semicircular canal and is due to excitation of its afferent nerves.

    The recent identification of highly superior autobiographical memory (HSAM) raised the possibility that there may be individuals who are immune to memory distortions. We measured HSAM participants’ and age- and sex-matched controls’ susceptibility to false memories using several research paradigms. HSAM participants and controls were both susceptible to false recognition of nonpresented critical lure words in an associative word-list task. In a misinformation task, HSAM participants showed higher overall false memory compared with that of controls for details in a photographic slideshow. HSAM participants were equally as likely as controls to mistakenly report they had seen nonexistent footage of a plane crash. Finding false memories in a superior-memory group suggests that malleable reconstructive mechanisms may be fundamental to episodic remembering. Paradoxically, HSAM individuals may retrieve abundant and accurate autobiographical memories using fallible reconstructive processes. PMID:24248358

    The form change paradigm was used to explore the basis for the picture superiority effect. Recognition memory for studied pictures and words was tested in their study form or the alternate form. Form change cost was defined as the difference between recognition performance for same and different form items. Based on the results of Experiment 1 and previous studies, it was difficult to determine the relative cost for studied pictures and words due to a reversal of the mirror effect. We hypothesized that the reversed mirror effect results from subjects' basing their recognition decisions on their assumptions about the study form. Experiments 2 and 3 confirmed this hypothesis and generated a method for evaluating the relative cost for pictures and words despite the reversed mirror effect. More cost was observed for pictures than words, supporting the distinctiveness model of the picture superiority effect.

    Highly Superior Autobiographical Memory (HSAM) is characterised as the ability to accurately recall an exceptional number of experiences and their associated dates from events occurring throughout much of one's lifetime. The source of this ability has only begun to be explored. The present study explores whether other enhanced cognitive processes may be critical influences underlying HSAM abilities. We investigated whether enhanced abilities in the domains of verbal fluency, attention/inhibition, executive functioning, mnemonic discrimination, perception, visual working memory, or the processing of and memory for emotional details might contribute critically to HSAM. The results suggest that superior cognitive functioning is an unlikely basis of HSAM, as only modest advantages were found in only a few tests. In addition, we examined HSAM subjects' memory of the testing episodes. Interestingly, HSAM participants recalled details of their own experiences far better than those experiences that the experimenter shared with them. These findings provide additional evidence that HSAM involves, relatively selectively, recollection of personal, autobiographical material.

    1983-01-01

    Computed tomography (CT) of the pancreas, with its excellent display of peripancreatic anatomy, allows visualization of the major vessels entering the mesenteric root. In scans of the normal upper abdomen obtained at or just below the level of the uncinate process of the pancreas, the proximal superior mesenteric vein (SMV) easily can be identified lying on the right ventral aspect of the superior mesenteric artery (SMA). The authors have observed a characteristic abnormality in this normal vascular arrangement on CT scans of the pancreas in three adult patients with suspected chronic pancreatitis who were subsequently proved to have midgut malrotation. They called this the SMV rotation sign and believe that its detection even on CT scans limited to the level of the pancreas should alert the radiologist to the presence of a midgut malrotation that may have been unsuspected

    Carbon dots (CDs) have various applications in biomedical and environmental field, such as bio-imaging, bio-sensing and heavy metal detection. In this study, a novel class of CDs were synthesized using a one-step hydrothermal method. The fabricated CDs displayed stable photoluminescence, good water solubility, and photo stability. Moreover, the functional groups (carboxylic acid moieties and hydroxyls) on the surface of the obtained CDs enable it with superior sensing ability (e.g., very low detectable concentration for Pb2+: 5 nmol/L). With superior detection sensitivity, excellent fluorescent properties and facile fabrication method, the as-obtained CDs can find practical applications as cost-effective and sensitive chemo-sensors in water and food safety field.

    Mycotic aneurysms of the aorta and the visceral arteries are life-threatening diseases, due to potential rupture and organ or limb ischemia. They occur in endocarditis, immunodeficiency, bacteremia and fungemia, and have a poor prognosis.We report on a case of a 54-year-old male patient suffering from abdominal angina after mitral valve replacement for septic mycotic endocarditis. In presence of a mycotic-embolic occlusion of the left popliteal artery and multiple septic organ infarctions a mycotic aneurysm of the superior mesenteric artery was found in abdominal spiral-CT.Based on sequential spiral-CT examinations, this case demonstrates the development of a septic aneurysm of the superior mesenteric artery.

    MRI examinations were carried out on the defined congenital superior oblique palsy in order to distinguish the congenital and acquired palsies. Subjects were 19 patients diagnosed as congenital and their MRI images of 3 or 5 mm-thick coronary slice were taken. The volume of the oblique muscle was calculated from the images and a comparison was made between the diseased and healthy normal sides. The oblique muscle volume at the diseased side was found reduced in most of congenital superior oblique palsy patients. The reduction was observed even at childhood and was thus considered to be a malformation. Further, it is conceivable that the palsy could be caused by the abnormality in the central nervous system as well as by the present anatomical abnormality. (K.H.)

    Full Text Available : Objective/Background: This report presents a superior mesenteric artery (SMA embolism managed by percutaneous mechanical thrombectomy (PMT. Methods: A 61 year old woman diagnosed with SMA embolism was admitted. Emboli were found in the middle and distal segments of the SMA on abdominal computed tomography angiography. Under local anaesthesia, a 6 F Rotarex system was used to remove the emboli via left brachial artery access. Emboli were successfully removed and patency was restored to the SMA and its branches. Results: Post-operatively, the patient's symptoms were significantly relieved. No post-operative complications were observed and no discomfort was documented during follow-up. Conclusion: Endovascular treatment of SMA embolism using PMT is a feasible and alternative option.

Its effect on the torsion of the eye is not known. We present our data on the effect of this particular procedure on torsion. Materials and Methods: We did a study of 16 patients (32 eyes who underwent bilateral SOSL and compared the disc foveal angle (DFA preoperatively and postoperatively. The split lengthening was done from 4 mm to 7 mm depending upon the overaction of superior oblique. Results: The mean age was 15.3 ± 8.4 years. Mean preoperative DFA in the right eye (RE was −3.9° and in the left eye (LE was −2.9°. Mean postoperative DFA in RE was 0.2° and in LE was 0.9°. The mean change in the DFA for RE was 4.1° ± 1.3° and for LE was 3.8° ± 1.2°. All the patients were aligned horizontally within 6 prism diopter and no pattern and no diplopia postoperatively. The A pattern was corrected in all the patient postsurgery. For each mm of surgery, an improvement of 0.8° was seen in the DFA. Conclusion: We report the effect of SOSL on torsion. The SOSL reduces intorsion postsurgery and is, therefore, a valuable procedure in SOOA where both pattern and in torsion needs to be corrected.

  16. Information Superiority generated through proper application of Geoinformatics

    2012-04-01

    Information Superiority generated through proper application of Geoinformatics Information management and especially geoscience information delivery is a very delicate task. If it is carried out successfully, geoscientific data will provide the main foundation of Information Superiority. However, improper implementation of geodata generation, assimilation, distribution or storage will not only waste valuable resources like manpower or money, but could also give rise to crucial deficiency in knowledge and might lead to potentially extremely harmful disasters or wrong decisions. Comprehensive Approach, Effect Based Operations and Network Enabled Capabilities are the current buzz terms in the security regime. However, they also apply to various interdisciplinary tasks like catastrophe relief missions, civil task operations or even in day to day business operations where geo-science data is used. Based on experience in the application of geoscience data for defence applications the following procedure or tool box for generating geodata should lead to the desired information superiority: 1. Understand and analyse the mission, the task and the environment for which the geodata is needed 2. Carry out a Information Exchange Requirement between the user or customer and the geodata provider 3. Implementation of current interoperability standards and a coherent metadata structure 4. Execute innovative data generation, data provision, data assimilation and data storage 5. Apply a cost-effective and reasonable data life cycle 6. Implement IT security by focusing of the three pillar concepts Integrity, Availability and Confidentiality of the critical data 7. Draft and execute a service level agreement or a memorandum of understanding between the involved parties 8. Execute a Continuous Improvement Cycle These ideas from the IT world should be transferred into the geoscience community and applied in a wide set of scenarios.

  19. Superior metallic alloys through rapid solidification processing (RSP) by design

    Energy Technology Data Exchange (ETDEWEB)

    Flinn, J.E. [Idaho National Engineering Laboratory, Idaho Falls, ID (United States)

    1995-05-01

    Rapid solidification processing using powder atomization methods and the control of minor elements such as oxygen, nitrogen, and carbon can provide metallic alloys with superior properties and performance compared to conventionally processing alloys. Previous studies on nickel- and iron-base superalloys have provided the baseline information to properly couple RSP with alloy composition, and, therefore, enable alloys to be designed for performance improvements. The RSP approach produces powders, which need to be consolidated into suitable monolithic forms. This normally involves canning, consolidation, and decanning of the powders. Canning/decanning is expensive and raises the fabrication cost significantly above that of conventional, ingot metallurgy production methods. The cost differential can be offset by the superior performance of the RSP metallic alloys. However, without the performance database, it is difficult to convince potential users to adopt the RSP approach. Spray casting of the atomized molten droplets into suitable preforms for subsequent fabrication can be cost competitive with conventional processing. If the fine and stable microstructural features observed for the RSP approach are preserved during spray casing, a cost competitive product can be obtained that has superior properties and performance that cannot be obtained by conventional methods.

  20. Levels of processing and picture memory: the physical superiority effect.

    Science.gov (United States)

    Intraub, H; Nicklos, S

    1985-04-01

    Six experiments studied the effect of physical orienting questions (e.g., "Is this angular?") and semantic orienting questions (e.g., "Is this edible?") on memory for unrelated pictures at stimulus durations ranging from 125-2,000 ms. Results ran contrary to the semantic superiority "rule of thumb," which is based primarily on verbal memory experiments. Physical questions were associated with better free recall and cued recall of a diverse set of visual scenes (Experiments 1, 2, and 4). This occurred both when general and highly specific semantic questions were used (Experiments 1 and 2). Similar results were obtained when more simplistic visual stimuli--photographs of single objects--were used (Experiments 5 and 6). As in the case of the semantic superiority effect with words, the physical superiority effect for pictures was eliminated or reversed when the same physical questions were repeated throughout the session (Experiments 4 and 6). Conflicts with results of previous levels of processing experiments with words and nonverbal stimuli (e.g., faces) are explained in terms of the sensory-semantic model (Nelson, Reed, & McEvoy, 1977). Implications for picture memory research and the levels of processing viewpoint are discussed.

    Full Text Available El ritmo de vida actual, tanto sociocultural como tecnológico, ha desembocado en un aumento de enfermedades y padecimientos que afectan las capacidades físico-motrices de los individuos. Esto ha originado el desarrollo de prototipos para auxiliar al paciente a recuperar la movilidad y la fortaleza de las extremidades superiores afectadas. El presente trabajo aborda el diseño de una estructura mecánica de un exoesqueleto con 4 grados de libertad para miembro superior. La cual tiene como principales atributos la capacidad de ajustarse a la antropometría del paciente mexicano (longitud del brazo, extensión del antebrazo, condiciones geométricas de la espalda y altura del paciente. Se aplicó el método BLITZ QFD para obtener el diseño conceptual óptimo y establecer adecuadamente las condiciones de carga de servicio. Por lo que, se definieron 5 casos de estudio cuasi-estáticos e implantaron condiciones para rehabilitación de los pacientes. Asimismo, mediante el Método de Elemento Finito (MEF se analizaron los esfuerzos y deformaciones a los que la estructura está sometida durante la aplicación de los agentes externos de servicio. Los resultados presentados en éste trabajo exhiben una nueva propuesta para la rehabilitación de pacientes con problemas de movilidad en miembro superior. Donde el equipo propuesto permite la rehabilitación del miembro superior apoyado en 4 grados de libertad (tres grados de libertad en el hombro y uno en el codo, el cual es adecuado para realizar terapias activas y pasivas. Asimismo, es un dispositivo que está al alcance de un mayor porcentaje de la población por su bajo costo y fácil desarrollo en la fabricación.

    Full Text Available El tabaquismo es una afección médica de carácter crónico caracterizada por la adicción a la nicotina. El 70% de los fumadores desea dejar de fumar, aunque sólo 30% lo intenta en un año. A los fumadores motivados se les debe ofrecer alguno de los tratamientos disponibles. Dentro del tratamiento farmacológico se distinguen los compuestos sin nicotina y la terapia de reemplazo con nicotina (TRN. En el primer grupo destacan el tartrato de vareniclina y los medicamentos antidepresivos como bupropión y nortriptilina. Dentro de la TRN se encuentran los parches, goma de mascar, tabletas sublinguales y orales, dispositivo de inhalación oral y aerosol nasal. El tartrato de vareniclina es un agonista parcial de los receptores nicotínicos cerebrales alfa4beta2 que reduce los síntomas de abstinencia, así como el deseo y urgencia por fumar. Los estudios muestran que vareniclina es superior a placebo (RM 3.22, IC95% 2.43-4.27 y también el bupropión (RM 1.66, IC95% 1.28-2.16. Todas las modalidades de TRN resultan efectivas (RM 1.78, IC95% 1.60-1.99 aunque, en casos particulares, alguna presentación puede resultar más conveniente. El potencial adictivo de los sustitutos de nicotina es menor que el del cigarrillo y además carece de los efectos tóxicos del humo. El bupropión estimula la función noradrenérgica y dopaminérgica y duplica la tasa de abstinencia en comparación con el parche de nicotina (RM 1.94, IC95% 1.72-2.19. La nortriptilina también se relaciona con aumento de las tasas de abstinencia (RM 2.34, IC95% 1.61-3.41. Otros tratamientos han mostrado cierta eficacia, entre los cuales destacan los bloqueadores de los receptores endocanabinoides, como el rimonabant. De los tratamientos no farmacológicos, el consejo médico es una herramienta útil, cuyo éxito puede ser de 2 a 4%, pero sólo 35% de los médicos lo aplican (RM 1.74, IC95% 1.48-2.05.

    Full Text Available The present study examined the correspondence between perceived and actual social discrimination of overweight people. In total, 77 first-year students provided self-ratings about their height, weight, and perceived social inclusion. To capture actual social inclusion, each participant nominated those fellow students a she/he likes and dislikes and b about whom she/he is likely to hear social news. Students with lower BMI felt socially included, irrespective of their actual social inclusion. In contrast, students with higher BMI felt socially included depending on the degree of their actual social inclusion. Specifically, their felt social inclusion accurately reflected whether they were actually liked/disliked, but only when they were part of social news. When not part of social news, they also showed insensitivity to their actual social inclusion status. Thus, students with a lower BMI tended to be insensitive, while students with a higher BMI showed a differential sensitivity to actual social discrimination.

That is the contradiction: if man has to control the drives, they are not harmonics. There is incompatibility between harmony and control. In other words, the superior man is indeed the man of culture and cultivated man of Nietzsche? If the answer to this question is yes, then, in this man, reigns the drives harmony. If, on the other hand, the answer is no, then, for this man does not become a barbarian destroyer, dangerous to himself and to others it is necessary that a drive dominates the others.

    1985-02-01

    Sciatica caused by root entrapment in the lateral recess was named superior facet syndrome by Epstein in 1972. Few reports on this subject based on large numbers of cases have been documented to date. Of the patients with sciatica, 32 patients were diagnosed to have root entrapment at the lateral recess L5 or/and S1 lumbar spine. Out of 32 patients, 20 patients were operated on and the lateral entrapment was recognized in all of surgical cases. Neuroradiological findings, especially of metrizamide CT (met. CT), were documented in detail. Thirty two patients were classified in three types according to radiological findings. They were congenital or developmental, degenerative, and combined type, respectively. Fourteen cases belonged to the congenital type, 13 to the degenerative and 5 to the combined type. Each group had the mean ages of 23.4, 53.8, and 36.8 years old, respectively. Of 32 cases the entrapment occured in 47 L5 roots and 11 S1 roots. There was no remarkable laterality. In operation the unroofing of the lateral recess were done and the sciatica subsided postoperatively in all of surgical cases. Met. CT revealed extreme medial protrusion of the superior articular joint in 18 of 24 cases(75%) and none filling of the root in the lateral recess in 21 of 24 cases (87.5%). In the degenerative type, met. CT showed some degenerative changes that were hypertrophy or deformity of the articular joints and spur formation of the vertebral body. In contrast to met. CT, metrizamide myelography revealed only slight changes, which were poor filling of the root before it turned out the pedicle of lateral compression of the root. In plain films or lumbar spine articular joints at Lsub(4/5) were formed in coronal plane in 69% of cases of the L5 root entrapment. Met. CT using ReView technique was of great diagnostic value in superior facet syndrome.

  11. Characterization of the superior olivary complex of Canis lupus domesticus.

    The superior olivary complex (SOC) is a collection of brainstem auditory nuclei which play essential roles in the localization of sound sources, temporal coding of vocalizations and descending modulation of the cochlea. Notwithstanding, the SOC nuclei vary considerably between species in accordance with the auditory needs of the animal. The canine SOC was subjected to anatomical and physiological examination nearly 50 years ago and was then virtually forgotten. Herein, we aimed to characterize the nuclei of the canine SOC using quantitative morphometrics, estimation of neuronal number, histochemistry for perineuronal nets and immunofluorescence for the calcium binding proteins calbindin and calretinin. We found the principal nuclei to be extremely well developed: the lateral superior olive (LSO) contained over 20,000 neurons and the medial superior olive (MSO) contained over 15,000 neurons. In nearly all non-chiropterian terrestrial mammals, the MSO exists as a thin, vertical column of neurons. The canine MSO was folded into a U-shaped contour and had associated with the ventromedial tip a small, round collection of neurons we termed the tail nucleus of the MSO. Further, we found evidence within the LSO, MSO and medial nucleus of the trapezoid body (MNTB) for significant morphological variations along the mediolateral or rostrocaudal axes. Finally, the majority of MNTB neurons were calbindin-immunopositive and associated with calretinin-immunopositive calyceal terminals. Together, these observations suggest the canine SOC complies with the basic plan of the mammalian SOC but possesses a number of unique anatomical features. Copyright © 2017 Elsevier B.V.

  14. QUAL DEMOCRATIZAÇÃO DO ENSINO SUPERIOR?

    Directory of Open Access Journals (Sweden)

    François Dubet

    Full Text Available Esse artigo, resultante de uma conferência, discute traços do processo de democratização do ensino superior. Procura distinguir analiticamente várias dimensões da democratização, baseadas, por sua vez, em concepções diferentes da justiça: igualdade de oportunidades, meritocracia, utilidades e equidade dos procedimentos. Cada sociedade constrói modelos de democratização desse ensino. A massificação do ensino superior desempenhou papel democrático objetivo, favorável aos grupos sociais antes excluídos. Mas massificação não equivale à democratização. Todas as categorias sociais não se beneficiam da mesma forma da massificação. A democratização do acesso ao ensino superior não depende apenas das famílias. Depende também da estrutura geral do sistema educativo. A meritocracia acadêmica constrói uma hierarquia de competências que é também social, com forte impacto reprodutivo. As desigualdades de utilidade das diferentes formações têm impacto sobre o conjunto das desigualdades sociais. Os sistemas educativos implementam distintos procedimentos de seleção, de concessão de gratuidades, bolsas e auxílios, que podem ser considerados como mais ou menos equitativos segundo as normas de justiça que mobilizam.

    Full Text Available Argentina es considerada por sus habitantes como el país más europeo de América Latina. La supuesta baja densidad aborigen al momento de la conquista y las Campañas al Desierto permitieron considerar que la población de nuestro país estaba constituida por descendientes de inmigrantes europeos con mínimo componente amerindio. El empleo del ADN mitocondrial (ADNmt y la región no recombinante del Cromosoma Y como marcadores permitieron el rastreo de linajes. Ambos sistemas exhiben características específicas en las poblaciones originarias de América. Para analizar la contribución amerindia a la población actual se seleccionaron 322 muestras de individuos varones no relacionados de nueve provincias agrupadas en tres grupos regionales. Se analizaron HVR I y II de la región de control y la ins/del de Región V del ADNmt, además se investigó la presencia de la transicion C-T en el locus DYS199 asi como 9 Y-STRs (DYS19, DYS385, DYS389 I y II, DYS390, DYS391, DYS392 y DYS393. Los resultados obtenidos indican que la contribución amerindia en los linajes maternos de nuestra población es superior al 50%, en tanto que la contribución de patrilineas amerindias se restringe al 20%, además un 10% de los individuos presentan ambos linajes amerindios. La contribución no amerindia se restringe a menos del 40%. Los resultados son semejantes en las regiones Nor-Noreste, Centro y Sur-SurOeste. Esta información confirmaría investigaciones previas aportadas por el análisis de grupos sanguíneos y otros marcadores serológicos. Este trabajo junto con otros aportes permitirán replantear la composición étnica de nuestro país redefiniendo su identidad.

    2017-10-01

    Persistent left superior vena cava (PLSVC) is a congenital anomaly, that results when there is an absence of the normal regression of the left common precardinal vein during embryogenesis. Usually, this anomaly remains asymptomatic, however, when the PLSVC drains into the left atrium this could lead to a right-to-left shunt. Additionally, this can result in inadvertent delivery of air or thrombus into the systemic circulation with potential neurologic, cardiac and renal complications. In this article, we present a case of an extreme premature Mexican newborn in which the diagnosis was made after placement of a percutaneous central venues catheter.

    The superior and inferior venae cavae may be involved in a host of disease processes. Knowledge of the normal anatomy and variants of these structures is valuable in interpreting plain films and the results of angiographic procedures and all cross-sectional modalities. The authors review the embryology of venae cavae and proceed to describe their normal anatomy and variants. An awareness of the variants can prevent mistaking variants for pathologic processes. Finally, the authors describe pathology involving these vessels and demonstrate the radiographic manifestations

  6. An auditory analog of the picture superiority effect.

    Crutcher, Robert J; Beer, Jenay M

    2011-01-01

    Previous research has found that pictures (e.g., a picture of an elephant) are remembered better than words (e.g., the word "elephant"), an empirical finding called the picture superiority effect (Paivio & Csapo. Cognitive Psychology 5(2):176-206, 1973). However, very little research has investigated such memory differences for other types of sensory stimuli (e.g. sounds or odors) and their verbal labels. Four experiments compared recall of environmental sounds (e.g., ringing) and spoken verbal labels of those sounds (e.g., "ringing"). In contrast to earlier studies that have shown no difference in recall of sounds and spoken verbal labels (Philipchalk & Rowe. Journal of Experimental Psychology 91(2):341-343, 1971; Paivio, Philipchalk, & Rowe. Memory & Cognition 3(6):586-590, 1975), the experiments reported here yielded clear evidence for an auditory analog of the picture superiority effect. Experiments 1 and 2 showed that sounds were recalled better than the verbal labels of those sounds. Experiment 2 also showed that verbal labels are recalled as well as sounds when participants imagine the sound that the word labels. Experiments 3 and 4 extended these findings to incidental-processing task paradigms and showed that the advantage of sounds over words is enhanced when participants are induced to label the sounds.

  7. Cognitive abilities and superior decision making under risk

    Directory of Open Access Journals (Sweden)

    Edward T. Cokely

    2009-02-01

    Full Text Available Individual differences in cognitive abilities and skills can predict normatively superior and logically consistent judgments and decisions. The current experiment investigates the processes that mediate individual differences in risky choices. We assessed working memory span, numeracy, and cognitive impulsivity and conducted a protocol analysis to trace variations in conscious deliberative processes. People higher in cognitive abilities made more choices consistent with expected values; however, expected-value choices rarely resulted from expected-value calculations. Instead, the cognitive ability and choice relationship was mediated by the number of simple considerations made during decision making --- e.g., transforming probabilities and considering the relative size of gains. Results imply that, even in simple lotteries, superior risky decisions associated with cognitive abilities and controlled cognition can reflect metacognitive dynamics and elaborative heuristic search processes, rather than normative calculations. Modes of cognitive control (e.g., dual process dynamics and implications for process models of risky decision-making (e.g., priority heuristic are discussed.

  8. Visual sensitivity of deepwater fishes in Lake Superior.

    Full Text Available The predator-prey interactions in the offshore food web of Lake Superior have been well documented, but the sensory systems mediating these interactions remain unknown. The deepwater sculpin, (Myoxocephalus thompsoni, siscowet (Salvelinus namaycush siscowet, and kiyi (Coregonus kiyi inhabit low light level environments. To investigate the potential role of vision in predator-prey interactions, electroretinography was used to determine visual sensitivity for each species. Spectral sensitivity curves revealed peak sensitivity at 525 nm for each species which closely corresponds to the prevalent downwelling light spectrum at depth. To determine if sufficient light was available to mediate predator-prey interactions, visual sensitivity was correlated with the intensity of downwelling light in Lake Superior to construct visual depth profiles for each species. Sufficient daytime irradiance exists for visual interactions to approximately 325 m for siscowet and kiyi and 355 m for the deepwater sculpin during summer months. Under full moon conditions, sufficient irradiance exists to elicit ERG response to light available at approximately 30 m for the siscowet and kiyi and 45 m for the deepwater sculpin. Visual interactions are therefore possible at the depths and times when these organisms overlap in the water column indicating that vision may play a far greater role at depth in deep freshwater lakes than had been previously documented.

  9. Spontaneous Superior Mesenteric Artery Branch Pseudoaneurysm: A Rare Case Report

    Directory of Open Access Journals (Sweden)

    Mina Guirgis

    Full Text Available : Background: Visceral arterial pseudoaneurysms (VAPAs are rare vascular entities with serious consequences. Traditionally, they are associated with trauma, infection, and inflammatory disease, or they can arise as a post-operative complication. Report: An 87 year old man presented with abdominal pain and was found to have a spontaneous VAPA on a computed tomography angiogram. Serial imaging 4 months previously had demonstrated no aneurysm. Between scans, warfarin was changed to apixaban for aortic valve replacement, but he had no other changes to any other medications. He required urgent endovascular coiling of the pseudoaneurysm, with satisfactory recovery and outcome. Discussion: VAPAs are extremely rare, with splenic artery VAPAs the most commonly reported. Regardless, fewer than 250 cases of splenic artery pseudoaneurysm have been reported. Superior mesenteric artery (SMA pseudoaneurysms are the rarest type of VAPAs. Early identification and urgent treatment are warranted because of the associated high mortality risk, with a 50% risk of rupture in any given VAPA. Treatment options range from open operation to endoscopic and endovascular procedures. Apixaban has been proposed to contribute to pseudoaneurysm formation by slow and continuous bleeding that results in the formation of the pseudoaneurysm. Conclusions: Spontaneous VAPAs are extremely rare and this is the first time a VAPA has been associated with the novel oral anticoagulant “apixaban”. Urgent management of any VAPAs is important because of the high risk of rupture and potential life threatening haemorrhage.

    Many nuclear power plants have been constructed in Japan and electric power generation is now highly dependent on this technology. Therefore, the needs for facilities that will enrich and reprocess nuclear fuel from nuclear power stations will be high. As there are areas with high levels of radiation, the cables which can be used in these environments are needed. We have developed a superior radiation-resistant cable which uses halogen flame-retardant materials. This radiation-resistant cable consists of Ethylene-propylene rubber (EPDM) insulation and Chlorosulfonated polyethylene (CSM) sheath can be safely used in areas with high levels of radiation. We developed this product to aid in disaster prevention. Non-halogen, flame-retardant EPDM is used for the insulation, and low-halogen, flame-retardant CSM and new non-halogen, flame-retardant materials are used for the sheath. These cables have superior flame-retardant properties and generate little smoke on corrosive gas. This products can hence reduce the danger of a secondary disaster in a fire. We expect that these cables will find application in areas with high levels of radiation. (author).

  12. Superior pre-attentive auditory processing in musicians.

    Koelsch, S; Schröger, E; Tervaniemi, M

    1999-04-26

    The present study focuses on influences of long-term experience on auditory processing, providing the first evidence for pre-attentively superior auditory processing in musicians. This was revealed by the brain's automatic change-detection response, which is reflected electrically as the mismatch negativity (MMN) and generated by the operation of sensoric (echoic) memory, the earliest cognitive memory system. Major chords and single tones were presented to both professional violinists and non-musicians under ignore and attend conditions. Slightly impure chords, presented among perfect major chords elicited a distinct MMN in professional musicians, but not in non-musicians. This demonstrates that compared to non-musicians, musicians are superior in pre-attentively extracting more information out of musically relevant stimuli. Since effects of long-term experience on pre-attentive auditory processing have so far been reported for language-specific phonemes only, results indicate that sensory memory mechanisms can be modulated by training on a more general level.

  13. A Cognitive Assessment of Highly Superior Autobiographical Memory

    Highly Superior Autobiographical Memory (HSAM) is characterized as the ability to accurately recall an exceptional number of experiences and their associated dates from events occurring throughout much of one’s lifetime. The source of this ability has only begun to be explored. The present study explores whether other enhanced cognitive processes may be critical influences underlying HSAM abilities. We investigated whether enhanced abilities in the domains of verbal fluency, attention/inhibition, executive functioning, mnemonic discrimination, perception, visual working memory, or the processing of and memory for emotional details might contribute critically to HSAM. The results suggest that superior cognitive functioning is an unlikely basis of HSAM, as only modest advantages were found in only a few tests. In addition, we examined HSAM subjects’ memory of the testing episodes. Interestingly, HSAM participants recalled details of their own experiences far better than those experiences that the experimenter shared with them. These findings provide additional evidence that HSAM involves, relatively selectively, recollection of personal, autobiographical material. PMID:26982996

    The advent of affordable Next Generation Sequencing technologies has had major impact on studies of many crop species, where access to genomic technologies and genome-scale data sets has been extremely limited until now. The recent development of genomic resources in blueberry will enable the application of high throughput gene expression approaches that should relatively quickly increase our understanding of blueberry physiology. These studies, however, require a highly accurate and robust workflow and make necessary the identification of reference genes with high expression stability for correct target gene normalization. To create a set of superior reference genes for blueberry expression analyses, we mined a publicly available transcriptome data set from blueberry for orthologs to a set of Arabidopsis genes that showed the most stable expression in a developmental series. In total, the expression stability of 13 putative reference genes was evaluated by qPCR and a set of new references with high stability values across a developmental series in fruits and floral buds of blueberry were identified. We also demonstrated the need to use at least two, preferably three, reference genes to avoid inconsistencies in results, even when superior reference genes are used. The new references identified here provide a valuable resource for accurate normalization of gene expression in Vaccinium spp. and may be useful for other members of the Ericaceae family as well.

  18. Superior and ICG - is there a good side to this?

    International Nuclear Information System (INIS)

    Jeffrey, S.

    1998-01-01

    The issue of whether the proposed merger between Superior Propane and ICG is in the best interest of the consumer was discussed. Petro-Canada, one of Canada's largest integrated oil and gas companies owns ICG. Norcen, a Canadian producer now owned by Union Pacific Resources, used to own Superior Propane. The merger of the two operations, which was driven by a rush to decrease competition, represents a total Canadian market share of 70 per cent or almost 2.5 billion litres of propane per year. Proponents of the merger argue that increased buying power will mean better prices at the plant gate, which will benefit the consumer. Opponents, on the other hand, argue that with low margins to combat, any savings realized will stay in the hands of the newly merged company. The bright side is that despite a huge market share of the newly merged company, there is still a potential to create small companies which understand their local market and which can provide customers with the kind of service they want

  19. Happy Face Superiority Effect in Change Detection Paradigm

    2013-09-01

    Full Text Available The aim of the present study was to investigate which affective component guides cognitive processing of emotional facial expressions. According to the threat hypothesis, processing of angry faces is prioritized by the human cognitive system, because rapid detection of threat has a large adaptive value. The negativity hypothesis presumes that distressing emotional experiences of other people attract attention, regardless of whether they represent danger or not. The emotionality hypothesis proposes that positive emotional facial expressions can capture attention as effective as negative ones, while the happy face superiority hypothesis predicts that happy faces are prioritized. In the present study, which was conducted on 24 participants, change detection paradigm was used, because that procedure enables insight into the later stage of information processing. The results obtained show that happy facial expressions are heavily prioritized by the human cognitive system. In explanation of these results, that clearly support the happy face superiority hypothesis, we propose that angry expressions are initially prioritized by our cognitive system, because we benefit from early detection of potential threat in the environment, but in later cognitive processing, happy expressions are given the priority, because smiling is a valuable mechanism for forming and maintaining cooperative relationships. Besides the theoretical relevance, the present study is also valuable methodologically, because we demonstrated that change detection paradigm can be efficiently used for the research of emotional facial expressions processing.

    Acromioplasty is increasingly being performed for both reparable and irreparable rotator cuff tears. However, acromioplasty may destroy the coracoacromial arch, including the coracoacromial ligament, consequently causing a deterioration in superior stability even after superior capsule reconstruction. The purpose of this study was to investigate the effects of acromioplasty on shoulder biomechanics after superior capsule reconstruction for irreparable supraspinatus tendon tears. The hypothesis was that acromioplasty with superior capsule reconstruction would decrease the area of subacromial impingement without increasing superior translation and subacromial contact pressure. Controlled laboratory study. Seven fresh-frozen cadaveric shoulders were evaluated using a custom shoulder testing system. Glenohumeral superior translation, the location of the humeral head relative to the glenoid, and subacromial contact pressure and area were compared among 4 conditions: (1) intact shoulder, (2) irreparable supraspinatus tendon tear, (3) superior capsule reconstruction without acromioplasty, and (4) superior capsule reconstruction with acromioplasty. Superior capsule reconstruction was performed using the fascia lata. Compared with the intact shoulder, the creation of an irreparable supraspinatus tear significantly shifted the humeral head superiorly in the balanced muscle loading condition (without superior force applied) (0° of abduction: 2.8-mm superior shift [P = .0005]; 30° of abduction: 1.9-mm superior shift [P = .003]) and increased both superior translation (0° of abduction: 239% of intact [P = .04]; 30° of abduction: 199% of intact [P = .02]) and subacromial peak contact pressure (0° of abduction: 308% of intact [P = .0002]; 30° of abduction: 252% of intact [P = .001]) by applying superior force. Superior capsule reconstruction without acromioplasty significantly decreased superior translation (0° of abduction: 86% of intact [P = .02]; 30° of abduction: 75

    We compared imagined versus actual affective and behavioral responses to witnessing a homophobic slur. Participants (N = 72) witnessed a confederate using a homophobic slur, imagined the same scenario, or were not exposed to the slur. Those who imagined hearing the slur reported significantly higher levels of negative affect than those who actually witnessed the slur, and nearly one half of them reported that they would confront the slur, whereas no participants who actually heard the slur confronted it. These findings reveal a discrepancy between imagined and real responses to homophobic remarks, and they have implications for the likelihood that heterosexuals will actually confront homophobic remarks.

    In psychoanalytic theory, the importance of actual neuroses-considered to be devoid of psychic content-diminished as Freud and subsequent analysts focused on unconscious intrapsychic conflict. This paper explores the relationship between actual neurotic and unrepresented states, which are believed to be best addressed through attention to countertransference, intersubjectivity, and enactments rather than interpretation of intrapsychic conflict. Models suggesting how actual neurotic states and symbolized intrapsychic conflict may interact with each other and environmental stressors are described. Symbolizing actual neurotic states and establishing meaningful linkages between somatic/affective experiences and intrapsychic conflict are viewed as necessary for effective treatment of many disorders. © 2017 The Psychoanalytic Quarterly, Inc.

    Sand Point is a small cuspate foreland located along the southeastern shore of Lake Superior within Pictured Rocks National Lakeshore near Munising, Michigan. Park managers’ concerns for the integrity of historic buildings at the northern periphery of the point during the rising lake levels in the mid-1980s greatly elevated the priority of research into the geomorphic history and age of Sand Point. To pursue this priority, we recovered sediment cores from four ponds on Sand Point, assessed subsurface stratigraphy onshore and offshore using geophysical techniques, and interpreted the chronology of events using radiocarbon and luminescence dating. Sand Point formed at the southwest edge of a subaqueous platform whose base is probably constructed of glacial diamicton and outwash. During the post-glacial Nipissing Transgression, the base was mantled with sand derived from erosion of adjacent sandstone cliffs. An aerial photograph time sequence, 1939–present, shows that the periphery of the platform has evolved considerably during historical time, infl uenced by transport of sediment into adjacent South Bay. Shallow seismic refl ections suggest slump blocks along the leading edge of the platform. Light detection and ranging (LiDAR) and shallow seismic refl ections to the northwest of the platform reveal large sand waves within a deep (12 m) channel produced by currents fl owing episodically to the northeast into Lake Superior. Ground-penetrating radar profi les show transport and deposition of sand across the upper surface of the platform. Basal radiocarbon dates from ponds between subaerial beach ridges range in age from 540 to 910 cal yr B.P., suggesting that Sand Point became emergent during the last ~1000 years, upon the separation of Lake Superior from Lakes Huron and Michigan. However, optically stimulated luminescence (OSL) ages from the beach ridges were two to three times as old as the radiocarbon ages, implying that emergence of Sand Point may have begun

    1999-01-01

    Acute dissection of the thoracic aorta is a well-recognized, often fatal condition that frequently extends to involve the abdominal aorta and iliac vessels. The ostia of the renal and mesenteric vessels may be compromised, and the resulting visceral ischemia may necessitate surgical intervention. However, visceral perfusion may be restored if blood flow from true to false lumen is re-established or if the false lumen is obliterated, either spontaneously or by surgical or interventional techniques. Isolated dissections of mesenteric, renal, and carotid vessels are rarely reported. These may be spontaneous, related to high blood pressure and underlying disease of the vessel wall, or caused by abdominal trauma or medical intervention, including angiographic procedures. They are usually associated with pain and other signs and symptoms of ischemia in the appropriate territory. We present a case of chronic superior mesenteric artery (SMA) dissection, an incidental angiographic finding, in an asymptomatic patient being evaluated for resection of an abdominal aortic aneurysm (AAA).

    Strong multiphoton absorption and harmonic generation in organic fluorescent chromophores are, respectively, significant in many fields of research. However, most of fluorescent chromophores fall short of the full potential due to the absence of the combination of such different nonlinear upconversion behaviors. Here, we demonstrate that an exceptional fluorescent stilbene dye could exhibit efficient two- and three-photon absorption under the excitation of femtosecond pulses in solution phase. Benefiting from its biocompatibility and strong excited state absorption behavior, in vitro two-photon bioimaging and superior optical limiting have been exploited, respectively. Simultaneously, the chromophore could generate efficient three-photon excited fluorescence and third-harmonic generation (THG) when dispersed into PMMA film, circumventing the limitations of classical fluorescent chromophores. Such chromophore may find application in the production of coherent light sources of higher photon energy. Moreover, the combination of three-photon excited fluorescence and THG can be used in tandem to provide complementary information in biomedical studies.

    2012-02-01

    AIM: To report a case of superior orbital fissure syndrome (SOFS) in a patient with herpes zoster ophthalmicus (HZO). MATERIALS AND METHODS: A case report. RESULTS: A 71-year-old male with HZO presented acutely to accident and emergency complaining of right vision loss, double vision and drowsiness. The right visual acuity was counting fingers. There was no relative afferent pupillary defect. He had interstitial keratitis, ptosis, proptosis and total ophthalmoplaegia. The signs indicated HZO complicated by SOFS. Brain imaging and lumbar puncture confirmed the diagnosis of varicella zoster encephalitis. Systemic acyclovir and prednisolone led to recovery of visual acuity and ocular motility in addition to resolution of his proptosis and ptosis. CONCLUSION: SOFS is a rare complication of herpes zoster infection. With the appropriate treatment and follow-up, patients may be reassured that recovery of their visual acuity and ocular motility will occur.

    Using a sample of Chinese security analysts’recommendations from 2005 to2010,we examine the source of analysts’superiority and the investment value of their recommendations.Using a calendar-time portfolio approach,we find that,on average,analysts’recommendations are valuable and that analysts are better at analyzing and transferring firm-specific information than market-wide or industry-level information.In addition,we show that the investment value of recommendations increases as firm-specific information becomes more important in stock pricing.Our empirical results are useful in guiding investors and helping brokerage houses to evaluate the output of research departments.

  3. The reproduction of lake trout in southern Lake Superior

    Science.gov (United States)

    Eschmeyer, Paul H.

    1955-01-01

    The principal spawning grounds of lake trout (Salvelinus namaycush namaycush) in United States waters of southern Lake Superior are on rocky shoals at depths of less than 20 fathoms. Most spawning occurs in October and early November. Of the mature fish collected on or near the spawning grounds, 60 to 69 percent were males. Among mature fish the average length of females was greater than that of males; few males less than 24 inches or females less than 26 inches in total length were caught. Recoveries of lake trout tagged on the spawning grounds showed that some males remained in the immediate area for a period of several weeks during the spawning season. Marked fish showed a tendency to return during later years to spawning grounds on which they had been tagged, even though many of them ranged long distances between spawning seasons.

    Human beings are social animals. This ability to live together is ensured by cognitive functions, the neuroanatomical bases of which are starting to be unraveled by MRI-based studies. The regions and network engaged in this process are known as the "social brain ". The core of this network is the superior temporal sulcus (STS), which integrates sensory and emotional inputs. Modeling studies of healthy volunteers have shown the role of the STS.in recognizing others as biological beings, as well as facial and eye-gaze recognition, intentionality and emotions. This cognitive capacity has been described as the "theory of mind ". Pathological models such as autism, in which the main clinical abnormality is altered social abilities and communication, have confirmed the role of the STS in the social brain. Conceptualisation of this empathic capacity has been described as "meta cognition ", which forms the basis of human social organizationand culture.

  5. Superior Mesenteric Vein Thrombosis Associated with Hormonal Contraceptive Use

    Full Text Available A 44-year-old woman was admitted with a 7-day history of lower abdominal pain and nausea. Physical examination demonstrated tenderness in the lower abdomen without signs of peritonitis. There were no specific findings in the laboratory evaluation. She had a history of dysmenorrhea for 15 years and was taking a combined hormonal contraceptive containing 0.02 mg ethinyl estradiol and 3 mg drospirenone for 19 months. Contrast-enhanced computed tomography showed superior mesenteric vein thrombosis (SMVT. Systemic anticoagulant infusion was immediately administered and the symptoms disappeared within 2 days. The thrombus disappeared after 3 months. This case report suggests that early diagnosis of SMVT and immediate systemic anticoagulant therapy may reduce the rate of intestinal infarction.

    Full Text Available O texto propõe retomar a universidade democrática como referência ética, em face dos desafios do mundo globalizado. Discute a situação atual das universidades, caracterizada como uma crise mundial no Ensino Superior, tendo como referência as IES dos Estados Unidos da América e do Canadá. São destacados três aspectos nessa questão-problema: 1- as consequências do movimento de globalização, que atinge todas as esferas da vida humana, entre elas a educação, e demandam do Ensino Superior o exercício da função de educar as gerações futuras para enfrentar os desafios de uma democracia global, evitando adotar a prática da indução dos professores e alunos à instrumentalização e ao imediatismo, subvalorizando o conhecimento crítico. 2- a retomada pelas universidades de seus objetivos de conhecimento e autonomia, posicionando-se contra a instrumentalização, a mercantilização e a militarização, essa última, como monitoramento de diferentes sujeitos sociais, e do Estado, exercidos sobre as IES. Para isso, propõe a colaboração inclusiva como uma das principais formas de divulgação da universidade e da importância da liberdade e da autonomia da Instituição Superior em suas decisões e ações. 3- a universidade acessível a todos que, além de possibilitar o desenvolvimento de uma educação crítica e de uma cultura intelectual verdadeira, adota metodologias prazerosas, estimulantes e capacitadoras, e valoriza os professores extinguindo os "contratos alternativos de trabalho" que têm contribuído para o empobrecimento da qualidade do Ensino Superior.The text proposes to reinstitute the democratic university as an ethic reference, given the challenges of the globalized world. It discusses the universities' current situation, which is characterized as a global crisis in higher education, taking as reference American and Canadian higher education institutions.

    The first synthesis of 131 I-19-iodocholesterol had a 10 to 25 percent radiochemical impurity that was not iodide ion. This impurity has been identified as 6β- 131 I-iodomethyl-19-nor cholest-5(10)-en-3β-ol (NP-59) and has been synthesized. Tissue distribution studies with 131 I-NP-59 in rats and dogs revealed a higher adrenal uptake and adrenal-to-tissue ratios compared to 131 I 19-iodocholesterol, probably less in vivo deiodination, and superior adrenal images. A high uptake was seen in the adrenal medulla in addition to that in the cortex. Iodine-131-NP-59 is being evaluated for the early detection of adrenal--cortical disorders and as a potential scanning agent for detecting structural abnormalities of the adrenal medulla

    1987-05-01

    A new immunoradiometric assay based on dual monoclonal antibody reaction system (Hybritech-TANDEM/sup R/) was used to measure serum levels of prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP) in 39 patients with prostatic carcinoma (CaP), in 57 with benign prostatic hyperplasia (BPH) and in 14 without prostatic disease. Serum PSA was elevated in 82% of patients with CaP while PAP was elevated in only 54%. In this and other studies, PSA is superior to conventional serum markers in sensitivity, prediction of CaP stage and in longitudinal monitoring of disease. A 16% false positive rate precludes PSA as a screening test. The assay used was found to be simple and reliable.

    2003-01-01

    For the LHC upgrade (fluences up to 10**1**6 p/cm**2) epi-Si devices are shown to be a viable solution. No type inversion was measured up to 1.3 multiplied by 10**1**524 GeV/c protons/cm**2 and the charge collection efficiency (CCE) remained close to 100%. For reactor neutrons CCE was measured to be 60% at 8 multiplied by 10**1**5 n/cm **2. Annealing measurements have shown that only moderate cooling during beam off periods would be necessary. As a tentative explanation for the superior quality of these devices, we assume that radiation-induced donor generation leads to compensation effects of deep acceptors. In the future, we will extend the experiments to fluences up to 10**1**6 p/cm**2 and use also different variants of the epi-Si material and device geometry.

    We reported the basal-plane thermal conductivity in exfoliated bilayer hexagonal boron nitride h-BN that was measured using suspended prepatterned microstructures. The h-BN sample suitable for thermal measurements was fabricated by dry-transfer method, whose sample quality, due to less polymer residues on surfaces, is believed to be superior to that of PMMA-mediated samples. The measured room temperature thermal conductivity is around 484 Wm−1K−1(+141 Wm−1K−1/ −24 Wm−1K−1) which exceeds that in bulk h-BN, providing experimental observation of the thickness-dependent thermal conductivity in suspended few-layer h-BN.

    P. O. Okunola

    2012-01-01

    Full Text Available Cerebral venous sinus (sinovenous thrombosis (CSVT is a rare life-threatening disorder in childhood that is often misdiagnosed. CSVT encompasses cavernous sinus thrombosis, lateral sinus thrombosis, and superior sagittal sinus thrombosis (SSST. We present an adolescent girl who was well until two weeks earlier when she had a throbbing frontal headache and fever with chills; she later had dyspnoea, jaundice, melena stool, multiple seizures, nuchal rigidity, and monoparesis of the right lower limb a day before admission. Urine test for Salmonella typhi Vi antigen was positive, and Widal reaction was significant. Serial cranial computerized tomography scans revealed an expanding hypodense lesion in the parafalcine region consistent with SSST or a parasagittal abscess. Inadvertent left parietal limited craniectomy confirmed SSST. She recovered completely with subsequent conservative management. Beyond neuropsychiatric complications of Typhoid fever, CSVT should be highly considered when focal neurologic deficits are present.

  15. Motor mechanisms of vertical fusion in individuals with superior oblique paresis.

    2002-06-01

    We wanted to determine the mechanisms of motor vertical fusion in patients with superior oblique paresis and to correlate these mechanisms with surgical outcomes. Ten patients with superior oblique paresis underwent 3-axis, bilateral, scleral search coil eye movement recordings. Eye movements associated with fusion were analyzed. Six patients had decompensated congenital superior oblique paresis and 4 had acquired superior oblique paresis. All patients with acquired superior oblique paresis relied predominantly on the vertical rectus muscles for motor fusion. Patients with congenital superior oblique paresis were less uniform in their mechanisms for motor fusion: 2 patients used predominantly the oblique muscles, 2 patients used predominantly the vertical recti, and 2 patients used predominantly the superior oblique in the hyperdeviated eye and the superior rectus in the hypodeviated eye. The last 2 patients developed the largest changes in torsional eye alignment relative to changes in vertical eye alignment and were the only patients to develop symptomatic surgical overcorrections. There are 3 different mechanisms for vertical fusion in individuals with superior oblique paresis, with the predominant mechanism being the vertical recti. A subset of patients with superior oblique paresis uses predominantly the superior oblique muscle in the hyperdeviated paretic eye and the superior rectus muscle in the fellow eye for fusion. This results in intorsion of both eyes, causing a large change in torsional alignment. The consequent cyclodisparity, in addition to the existing vertical deviation, may make fusion difficult. The differing patterns of vertical fusional vergence may have implications for surgical treatment.

    A multiyear field study was undertaken on Lake Superior to investigate singlet oxygen ((1)O(2)) photoproduction. Specifically, trends within the lake were examined, along with an assessment of whether correlations existed between chromophoric dissolved organic matter (CDOM) characteristics and (1)O(2) production rates and quantum yields. Quantum yield values were determined and used to estimate noontime surface (1)O(2) steady-state concentrations ([(1)O(2)](ss)). Samples were subdivided into three categories based on their absorbance properties (a300): riverine, river-impacted, or open lake sites. Using calculated surface [(1)O(2)](ss), photochemical half-lives under continuous summer sunlight were calculated for cimetidine, a pharmaceutical whose reaction with (1)O(2) has been established, to be on the order of hours, days, and a week for the riverine, river-impacted, and open lake waters, respectively. Of the CDOM properties investigated, it was found that dissolved organic carbon (DOC) and a300 were the best parameters for predicting production rates of [(1)O(2)](ss). For example, given the correlations found, one could predict [(1)O(2)](ss) within a factor of 4 using a300 alone. Changes in the quantum efficiency of (1)O(2) production upon dilution of river water samples with lake water samples demonstrated that the CDOM found in the open lake is not simply diluted riverine organic matter. The open lake pool was characterized by low absorption coefficient, low fluorescence, and low DOC, but more highly efficient (1)O(2) production and predominates the Lake Superior system spatially. This study establishes that parameters that reflect the quantity of CDOM (e.g., a300 and DOC) correlate with (1)O(2) production rates, while parameters that characterize the absorbance spectrum (e.g., spectral slope coefficient and E2:E3) correlate with (1)O(2) production quantum yields.

    Full Text Available Nuestra investigación trata el fenómeno del bullying en el ciclo superior de primaria. Para llevarla a cabo, hemos elaborado un cuestionario ad hoc a partir de una revisión bibliográfica de diferentes investigaciones en las que se han utilizado varios instrumentos, pruebas, cuestionarios... Este instrumento nos ha servido para analizar diferentes temas: la percepción que tienen los niños de ciclo superior sobre el bullying, en qué escenarios del centro escolar se producen más estos comportamientos, los diferentes tipos de bullying (físico, verbal y exclusión social y cuáles se producen más a menudo y analizar las respuestas que nos dan los alumnos en función del género y del curso (5.º y 6.º. Los resultados que hemos obtenido muestran, entre otras cosas: que en los niños se da más el bullying físico, mientras que en las niñas predomina el de tipo verbal y exclusión social; que la única diferencia según el curso es que en 6.º curso se da más exclusión social que en 5.º curso; y que donde se producen más conductas de bullying es en el patio, seguido del aula cuando no se encuentra el docente. Finalmente, partiendo de los resultados obtenidos, hemos elaborado unas propuestas de actuación psicopedagógicas para mejorar la convivencia en la escuela y otros espacios educativos.

  19. Frontal and superior temporal auditory processing abnormalities in schizophrenia.

    Although magnetoencephalography (MEG) studies show superior temporal gyrus (STG) auditory processing abnormalities in schizophrenia at 50 and 100 ms, EEG and corticography studies suggest involvement of additional brain areas (e.g., frontal areas) during this interval. Study goals were to identify 30 to 130 ms auditory encoding processes in schizophrenia (SZ) and healthy controls (HC) and group differences throughout the cortex. The standard paired-click task was administered to 19 SZ and 21 HC subjects during MEG recording. Vector-based Spatial-temporal Analysis using L1-minimum-norm (VESTAL) provided 4D maps of activity from 30 to 130 ms. Within-group t-tests compared post-stimulus 50 ms and 100 ms activity to baseline. Between-group t-tests examined 50 and 100 ms group differences. Bilateral 50 and 100 ms STG activity was observed in both groups. HC had stronger bilateral 50 and 100 ms STG activity than SZ. In addition to the STG group difference, non-STG activity was also observed in both groups. For example, whereas HC had stronger left and right inferior frontal gyrus activity than SZ, SZ had stronger right superior frontal gyrus and left supramarginal gyrus activity than HC. Less STG activity was observed in SZ than HC, indicating encoding problems in SZ. Yet auditory encoding abnormalities are not specific to STG, as group differences were observed in frontal and SMG areas. Thus, present findings indicate that individuals with SZ show abnormalities in multiple nodes of a concurrently activated auditory network.

    The superior frontal gyrus (SFG) is located at the superior part of the prefrontal cortex and is involved in a variety of functions, suggesting the existence of functional subregions. However, parcellation schemes of the human SFG and the connection patterns of each subregion remain unclear. We firstly parcellated the human SFG into the anteromedial (SFGam), dorsolateral (SFGdl), and posterior (SFGp) subregions based on diffusion tensor tractography. The SFGam was anatomically connected with the anterior and mid-cingulate cortices, which are critical nodes of the cognitive control network and the default mode network (DMN). The SFGdl was connected with the middle and inferior frontal gyri, which are involved in the cognitive execution network. The SFGp was connected with the precentral gyrus, caudate, thalamus, and frontal operculum, which are nodes of the motor control network. Resting-state functional connectivity analysis further revealed that the SFGam was mainly correlated with the cognitive control network and the DMN; the SFGdl was correlated with the cognitive execution network and the DMN; and the SFGp was correlated with the sensorimotor-related brain regions. The SFGam and SFGdl were further parcellated into three and two subclusters that are well corresponding to Brodmann areas. These findings suggest that the human SFG consists of multiple dissociable subregions that have distinct connection patterns and that these subregions are involved in different functional networks and serve different functions. These results may improve our understanding on the functional complexity of the SFG and provide us an approach to investigate the SFG at the subregional level. Copyright © 2013 Elsevier Inc.

  1. No actual measurement … was required: Maxwell and Cavendish's null method for the inverse square law of electrostatics.

    Science.gov (United States)

    Falconer, Isobel

    In 1877 James Clerk Maxwell and his student Donald MacAlister refined Henry Cavendish's 1773 null experiment demonstrating the absence of electricity inside a charged conductor. This null result was a mathematical prediction of the inverse square law of electrostatics, and both Cavendish and Maxwell took the experiment as verifying the law. However, Maxwell had already expressed absolute conviction in the law, based on results of Michael Faraday's. So, what was the value to him of repeating Cavendish's experiment? After assessing whether the law was as secure as he claimed, this paper explores its central importance to the electrical programme that Maxwell was pursuing. It traces the historical and conceptual re-orderings through which Maxwell established the law by constructing a tradition of null tests and asserting the superior accuracy of the method. Maxwell drew on his developing 'doctrine of method' to identify Cavendish's experiment as a member of a wider class of null methods. By doing so, he appealed to the null practices of telegraph engineers, diverted attention from the flawed logic of the method, and sought to localise issues around the mapping of numbers onto instrumental indications, on the grounds that 'no actual measurement … was required'.

    Full Text Available En este artículo se plantea una reflexión acerca de la necesidad de mirar la formación profesional de Enfermería desde una nueva perspectiva de diversidad etárea. Habitualmente la iniciación formativa en estas instituciones se da a una edad cronológica y social donde sin ser ya adolescentes podríamos tener una mezcla de juventud y suficiente madurez, aún libre de la carga de responsabilidades; pero también hay una demanda de educación superior que actualmente significa el ingreso de otro tipo de juventud (30 y 40 años. Pretendemos reflexionar acerca de la necesaria resignificación del proceso de aprendizaje acorde a la población de estudiantes que ingresan a estas instituciones y también sobre la pertinencia en la formación para el desarrollo de competencias, que respondiendo a los imperativos del contexto actual, mantenga la premisa en donde la educación sigue siendo un mecanismo para lograr igualdad de oportunidades. Por tanto, es importante tensionar los procesos pedagógicos de estas instituciones referentes a estas exigencias actuales. Abstract This article presents a reflection on the need to look professional Nursing training in a new age perspective of diversity. Usually admission to these institutions is a time and age where we have social mix of teenagers and youth without being unloaded necessary maturity of liabilities, but currently the demand for higher education has meant the entry of other youth (30 to 40 years. We intend to reflect on the necessary redefinition of the learning process according to the population of students entering these institutions and also on the relevance in training for skills development that respond to the demands of the current context, keeping the premise where education remains a mechanism for achieving equal opportunities. It is therefore important to stress the teaching processes of these institutions regarding these current requirements.

  18. Comparison of actual and predicted routes used in the shipment of radioactive materials

    International Nuclear Information System (INIS)

    Joy, D.S.; Johnson, P.E.; Harrison, I.G.

    1985-01-01

    A number of highway controlled shipments of radioactive materials have been made over the past several years. An excellent example showing the variability of actual routes is the transfer of 45 shipments between the Three Mile Island reactor in Pennsylvania and Scoville, Idaho in 1982 and 1983. Six different routes varying between 2273 and 2483 miles were used. Approximately 75% of these shipments followed a common route which passed through ten Urbanized Areas, defined by the Census Bureau as having a population exceeding 100,000 people. Other routes, while shorter in distance, passed through as many as 14 Urbanized Areas. Routes predicted by the Oak Ridge routing model did not exactly duplicate actual routes used. However, the analysis shows that the routing model does make a good estimate of transportation routes actually chosen by shippers of radioactive materials. In actual practice, a number of factors (weather, road conditions, driver preference, etc.) influence the actual route taken. 5 refs., 1 fig., 1 tab
