    2013-01-01

    47,XXY (Klinefelter syndrome) is the most frequent sex chromosomal disorder and affects approximately one in 660 newborn boys. The syndrome is characterized by varying degrees of cognitive, social, behavioral, and learning difficulties and in adulthood additionally primary testicular failure...... with small testes, hypergonadotropic hypogonadism, tall stature, and eunuchoid body proportions. The phenotype is variable ranging from "near-normal" to a significantly affected individual. In addition, newborns with Klinefelter syndrome generally present with a normal male phenotype and the only consistent...... clinical finding in KS is small testes, that are most often not identified until after puberty. Decreased awareness of this syndrome among health professionals and a general perception that all patients with 47,XXY exhibit the classic textbook phenotype results in a highly under-diagnosed condition with up...

    Mountain glaciers are vital sources of water worldwide to many densely-populated regions. Most glaciers are now shrinking, resulting in variable water supplies and sustained sea level rise. Rapid glacier change threatens water, energy and food security. Further glacier mass loss is likely in response to recent climate change, driven by global increases in air temperatures and the production of atmospheric pollutants. However, high altitudes and rugged topography generate regional weather systems that complicate the investigation of the relationship between climate and glacier change. Predictive models need to move beyond the state-of-the-art to couple advanced climate models with accurate representations of glacier processes, and more detailed and reliable data describing the state of mountain glaciers are required to constrain these models, both from monitoring individual glaciers and regional remote-sensing observations. Glaciation exists on the territory of Russia for thousands of years. At present both mountain glaciers and continental ice sheets are present there. Continental ice sheets are located on islands and archipelagoes of Russian Arctic region and mountain glaciers are wide-spread on continental part of the country where it currently covers the area of about 3,480,000 km². Now there are 18 mountain glacier regions on the territory of Russia. We present recent data on glaciers state and changes in mountain regions of Russia based on remote sensing and in situ studies and distribution of main climatic parameters that affect the existence of glaciers: summer air temperature, winter precipitations and maximum value of snow thickness.

    This volume (2), which consists of two parts (A and B), of the Plasma Diagnostics Package (PDP) Final Science Report contains a summary of all of the data reduction and scientific analyses which were performed using PDP data obtained on STS-51F as a part of the Spacelab 2 (SL-2) payload. This work was performed during the period of launch, July 29, l985, through June 30, l988. During this period the primary data reduction effort consisted of processing summary plots of the data received by 12 of the 14 instruments located on the PDP and submitting these data to the National Space Science Data Center (NSSDC). The scientific analyses during the performance period consisted of follow-up studies of shuttle orbiter environment and orbiter/ionosphere interactions and various plasma particle and wave studies which dealt with data taken when the PDP was on the Remote Manipulator System (RMS) arm and when the PDP was in free flight. Of particular interest during the RMS operations and free flight were the orbiter wake studies and joint studies of beam/plasma interactions with the SL-2 Fast Pulse Electron Generator (FPEG) of the Vehicle Charging and Potential Investigation (VCAP). Internal reports, published papers and presentations which involve PDP/SL-2 data are listed in Sections 3 and 4. A PDP/SL-2 scientific results meeting was held at the University of Iowa on June 10, l986. This meeting was attended by most of the PDP and VCAP investigators and provided a forum for discussing and comparing the various results, particularly with regard to the PDP free flight.

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

  18. Characterization of large volume HPGe detectors. Part II: Experimental results

    International Nuclear Information System (INIS)

    Bruyneel, Bart; Reiter, Peter; Pascovici, Gheorghe

    2006-01-01

    Measurements on a 12-fold segmented, n-type, large volume, irregular shaped HPGe detector were performed in order to determine the parameters of anisotropic mobility for electrons and holes as charge carriers created by γ-ray interactions. To characterize the electron mobility the complete outer detector surface was scanned in small steps employing photopeak interactions at 60keV. A precise measurement of the hole drift anisotropy was performed with 356keV γ-rays. The drift velocity anisotropy and crystal geometry cause considerable rise time differences in pulse shapes depending on the position of the spatial charge carrier creation. Pulse shapes of direct and transient signals are reproduced by weighting potential calculations with high precision. The measured angular dependence of rise times is caused by the anisotropic mobility, crystal geometry, changing field strength and space charge effects. Preamplified signals were processed employing digital spectroscopy electronics. Response functions, crosstalk contributions and averaging procedures were taken into account implying novel methods due to the segmentation of the Ge-crystal and digital signal processing electronics

  2. Nuclear fuel technology - Tank calibration and volume determination for nuclear materials accountancy - Part 1: Procedural overview

    International Nuclear Information System (INIS)

    2007-01-01

    Accurate determinations of volume are a fundamental component of any measurement-based system of control and accountability in a facility that processes or stores nuclear materials in liquid form. Volume determinations are typically made with the aid of a calibration or volume measurement equation that relates the response of the tank's measurement system to some independent measure of tank volume. The ultimate purpose of the calibration exercise is to estimate the tank's volume measurement equation (the inverse of the calibration equation), which relates tank volume to measurement system response. The steps carried out to acquire data for estimating the tank's calibration or volume measurement equation are collectively described as the process of tank calibration. This part of ISO 18213 describes procedures for tank calibration and volume determination for nuclear process tanks equipped with pressure-measurement systems for determining liquid content. Specifically, overall guidance is provided for planning a calibration exercise undertaken to obtain the data required for the measurement equation to estimate a tank's volume. The key steps in the procedure are also presented for subsequently using the estimated volume-measurement equation to determine tank liquid volumes. The procedures presented apply specifically to tanks equipped with bubbler probe systems for measuring liquid content. Moreover, these procedures produce reliable results only for clear (i.e. without suspended solids), homogeneous liquids that are at both thermal and static equilibrium. The paper elaborates on scope, physical principles involved, the calibration model, equipment required, a typical tank calibration procedure, calibration planning and pre-calibration activities, and volume determination. A bibliography is provided

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

    Changes in reimbursements for clinical laboratory testing may help us assess the effect of various variables, such as testing recommendations, market forces, changes in testing technology, and changes in clinical or laboratory practices, and provide information that can influence health care and public health policy decisions. To date, however, there has been no report, to our knowledge, of longitudinal trends in national laboratory test use. To evaluate Medicare Part B-reimbursed volumes of selected laboratory tests per 10,000 enrollees from 2000 through 2010. Laboratory test reimbursement volumes per 10,000 enrollees in Medicare Part B were obtained from the Centers for Medicare & Medicaid Services (Baltimore, Maryland). The ratio of the most recent (2010) reimbursed test volume per 10,000 Medicare enrollees, divided by the oldest data (usually 2000) during this decade, called the volume ratio, was used to measure trends in test reimbursement. Laboratory tests with a reimbursement claim frequency of at least 10 per 10,000 Medicare enrollees in 2010 were selected, provided there was more than a 50% change in test reimbursement volume during the 2000-2010 decade. We combined the reimbursed test volumes for the few tests that were listed under more than one code in the Current Procedural Terminology (American Medical Association, Chicago, Illinois). A 2-sided Poisson regression, adjusted for potential overdispersion, was used to determine P values for the trend; trends were considered significant at P reimbursement volumes were electrolytes, digoxin, carbamazepine, phenytoin, and lithium, with volume ratios ranging from 0.27 to 0.64 (P reimbursement volumes were meprobamate, opiates, methadone, phencyclidine, amphetamines, cocaine, and vitamin D, with volume ratios ranging from 83 to 1510 (P reimbursement volumes increased for most of the selected tests, other tests exhibited statistically significant downward trends in annual reimbursement volumes.

    This is the second part of the two-volume treatise by this well-known and respected author. This volume reviews applications of inductively coupled plasma atomic emission spectroscopy (ICP-AES), summarizes fundamental studies, and compares ICP-AES methods with other methods of analysis. The first six chapters are devoted to specific fields of application, including the following: metals and other industrial materials, geology, the environment, agriculture and food, biology and clinical analysis, and organic materials. The chapter on the analysis of organic materials also covers the special instrumental considerations required when organic solvents are introduced into an inductively coupled plasma. A chapter on the direct analysis of solids completes the first part of this volume. Each of the applications chapters begins with a summary of the types of samples that are encountered in that field, and the kinds of problems that an elemental analysis can help to solve. This is followed by a tutorial approach covering applicability, advantages, and limitations of the methods. The coverage is thorough, including sample handling, storage, and preparation, acid, and fusion dissolution, avoiding contamination, methods of preconcentration, the types of interferences that can be expected and ways to reduce them, and the types of ICP plasmas that are used. The second half of the volume covers fundamental studies of ICP-AES: basic processes of aerosol generation, plasma modeling and computer simulation, spectroscopic diagnostics, excitation mechanisms, and discharge characteristics.

    Volume 13a of the 'Chemical Thermodynamics' (TDB) series, is the first of two volumes describing the selection of chemical thermodynamic data for species of iron. Because of the voluminous information in the literature, it has been more efficient to prepare the review in two (unequal) parts. This larger first part contains assessments of data for the metal, simple ions, aqueous hydroxido, chlorido, sulfido, sulfato and carbonato complexes, and for solid oxides and hydroxides, halides, sulfates, carbonates and simple silicates. The second part will provide assessments of data for other aqueous halido species, sulfide solids, and solid and solution species with nitrate, phosphate and arsenate, as well as some aspects of solid solutions in iron-oxide and iron-sulfide systems. The database system developed at the OECD/NEA Data Bank ensures consistency not only within the recommended data sets of iron, but also among all the data sets published in the series. This volume will be of particular interest to scientists carrying out performance assessments of deep geological disposal sites for radioactive waste

  10. Optimal repairable spare-parts procurement policy under total business volume discount environment

    International Nuclear Information System (INIS)

    In asset intensive fields, where components are expensive and high system availability is required, spare parts procurement is often a critical issue. To gain competitiveness and market share is common for vendors to offer Total Business Volume Discounts (TBVD). Accordingly, companies must define the procurement and stocking policy of their spare parts in order to reduce procurement costs and increase asset availability. In response to those needs, this work presents an optimization model that maximizes the availability of the equipment under a TBVD environment, subject to a budget constraint. The model uses a single-echelon structure where parts can be repaired. It determines the optimal number of repairable spare parts to be stocked, giving emphasis on asset availability, procurement costs and service levels as the main decision criteria. A heuristic procedure that achieves high quality solutions in a fast and time-consistent way was implemented to improve the time required to obtain the model solution. Results show that using an optimal procurement policy of spare parts and accounting for TBVD produces better overall results and yields a better availability performance. - Highlights: • We propose a model for procurement of repairable components in single-echelon and business volume discount environments. • We used a mathematical model to develop a competitive heuristic that provides high quality solutions in very short times. • Our model places emphasis on using system availability, procurement costs and service levels as leading decision criteria. • The model can be used as an engine for a multi-criteria Decision Support System.

    As part III of this series, the model is extended to iron oxide-containing melts. All available experimental data in the FeO-Fe2O3-Na2O-K2O-MgO-CaO-MnO-Al2O3-SiO2 system were critically evaluated based on the experimental condition. The variations of FeO and Fe2O3 in the melts were taken into account by using FactSage to calculate the Fe2+/Fe3+ distribution. The molar volume model with unary and binary model parameters can be used to predict the molar volume of the molten oxide of the Li2O-Na2O-K2O-MgO-CaO-MnO-PbO-FeO-Fe2O3-Al2O3-SiO2 system in the entire range of compositions, temperatures, and oxygen partial pressures from Fe saturation to 1 atm pressure.

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

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

  3. Nuclear fuel technology - Tank calibration and volume determination for nuclear materials accountancy - Part 2: Data standardization for tank calibration

    International Nuclear Information System (INIS)

    2007-01-01

    Measurements of the volume and height of liquid in a process accountancy tank are often made in order to estimate or verify the tank's calibration or volume measurement equation. The calibration equation relates the response of the tank's measurement system to some independent measure of tank volume. The ultimate purpose of the calibration exercise is to estimate the tank's volume measurement equation (the inverse of the calibration equation), which relates tank volume to measurement system response. In this part of ISO 18213, it is assumed that the primary measurement-system response variable is liquid height and that the primary measure of liquid content is volume. This part of ISO 18213 presents procedures for standardizing a set of calibration data to a fixed set of reference conditions so as to minimize the effect of variations in ambient conditions that occur during the measurement process. The procedures presented herein apply generally to measurements of liquid height and volume obtained for the purpose of calibrating a tank (i.e. calibrating a tank's measurement system). When used in connection with other parts of ISO 18213, these procedures apply specifically to tanks equipped with bubbler probe systems for measuring liquid content. The standardization algorithms presented herein can be profitably applied when only estimates of ambient conditions, such as temperature, are available. However, the most reliable results are obtained when relevant ambient conditions are measured for each measurement of volume and liquid height in a set of calibration data. Information is provided on scope, physical principles, data required, calibration data, dimensional changes in the tank, multiple calibration runs and results on standardized calibration data. Four annexes inform about density of water, buoyancy corrections for mass determination, determination of tank heel volume and statistical method for aligning data from several calibration runs.

    Motivated by new energetic constraints and the interest of biomass, the authors report a bibliographical survey of studies concerning the evaluation of the available forest biomass. They comment the geographical and time distribution of the identified and compiled studies. They analyse their different topics. Then, they discuss the various field hypotheses, discuss and comments various resource assessment methodologies. They comment the resource the French forest can be, present a synthesis of the available resource at the regional level according to the different studies. They propose a review of some technical-economical aspects (costs, energy cost, price evolutions, improvement of the wood-energy mobilization). The second part proposes a whole set of volume calculations for different forest types (clusters or plantations of trees, copses, sawmills products), for industry and household consumption. It discusses the available volumes with respect to accessibility, additional available volumes, and possible improvements. The third part analyses, comments and discusses the wood market and wood energetic uses, and the possible supply curves for wood energetic uses by 2016

    1994-03-01

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

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

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

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

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

    An environmental assessment of the Cold Lake Expansion Project has been conducted to identify major issues of concern by public and government agencies, to determine means to eliminate or reduce those impacts, and to recommend any further efforts required to obtain missing information or monitor impacts. Volume 2 of the environmental impact assessment is divided into two parts. Part 1 (biophysical and resource use assessment) constitutes the primary environmental impact assessment document for the Cold Lake expansion project. It includes technical support documentation in regard to: (1) an assessment of noise impacts, (2) an assessment of greenhouse gas emissions, (3) a conceptual conservation and reclamation plan, (4) a historical resource impact assessment, and (5) a description of effects of oil spills on fish. Part 2 (impact model description) serves a reference document for part 1. It describes the approach taken in developing and assessing the impact models, discusses proposed methods for mitigation and management of residual impacts, and the recommended monitoring requirements for each of the major resource disciplines. The impact models describe the specific pathways through which impacts will occur as a result of interactions between project-related activities and important environmental components. 476 refs., 58 tabs., 23 figs

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

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

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

    Evolución, Oportunidades y Retos

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

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

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

    Steady-state, total-dose radiation test data, are provided in graphic format for use by electronic designers and other personnel using semiconductor devices in a radiation environment. The data were generated by JPL for various NASA space programs. This volume provides data on integrated circuits. The data are presented in graphic, tabular, and/or narrative format, depending on the complexity of the integrated circuit. Most tests were done using the JPL or Boeing electron accelerator (Dynamitron) which provides a steady-state 2.5 MeV electron beam. However, some radiation exposures were made with a cobalt-60 gamma ray source, the results of which should be regarded as only an approximate measure of the radiation damage that would be incurred by an equivalent electron dose

    1983-01-01

    Artificial Intelligence (AI) is an emerging technology that has recently attracted considerable attention. Many applications are now under development. The goal of Artificial Intelligence is focused on developing computational approaches to intelligent behavior. This goal is so broad - covering virtually all aspects of human cognitive activity - that substantial confusion has arisen as to the actual nature of AI, its current status and its future capability. This volume, the first in a series of NBS/NASA reports on the subject, attempts to address these concerns. Thus, this report endeavors to clarify what AI is, the foundations on which it rests, the techniques utilized, applications, the participants and, finally, AI's state-of-the-art and future trends. It is anticipated that this report will prove useful to government and private engineering and research managers, potential users, and others who will be affected by this field as it unfolds.

    The International Nuclear Model (INM) is a comprehensive model of the commercial nuclear power industry. It simulates economic decisions for reactor deployment and fuel management decisions based on an input set of technical, economic and scenario parameters. The technical parameters include reactor operating characteristics, fuel cycle timing and mass loss factors, and enrichment tails assays. Economic parameters include fuel cycle costs, financial data, and tax alternatives. INM has a broad range of scenario options covering, for example, process constraints, interregional activities, reprocessing, and fuel management selection. INM reports reactor deployment schedules, electricity generation, and fuel cycle requirements and costs. It also has specialized reports for extended burnup and permanent disposal. This volume contains appendices A through H including a description of subroutines and the Fortran listing of the program

    Full Text Available Recuerdo que hace dos meses vine a participar en el seminario organizado por el Serpaj (Servicio de Paz y Justicia; ahora estoy particularmente feliz de estar nuevamente con ustedes para hablar sobre el Socialismo del siglo XXI y la Iglesia del siglo XXI. De hecho, el tema es realmente de actualidad puesto que en América Latina vivimos por primera vez esta situación, después de mucho tiempo, en el que pasamos de las resistencias a las alternativas, no digo que sea la alternativa definitiva, pero se trata de pasos en dirección de las alternativas. América Latina es el único continente en el mundo actual que experimenta alternativas. Si consideramos por ejemplo el Asia, allí se vive el neoliberalismo más como una oportunidad que como una agresión. Es muy claro para la opinión general en América Latina que el neoliberalismo ha sido una agresión económica, política, cultural. En cambio, en países como la India,Vietnam y China se mira el neoliberalismo o el capitalismo tal vez como una oportunidad, por eso estamos todavía en estado, no solamente de construcción de alternativas, sino aún de resistencias.

    In our earlier work, we have demonstrated that it is possible to characterize binary mixtures using single component descriptors by applying various mixing rules. We also showed that these methods were successful in building predictive QSPR models to study various mixture properties of interest. Here in, we developed a QSPR model of an excess thermodynamic property of binary mixtures i.e. excess molar volume (V(E) ). In the present study, we use a set of mixture descriptors which we earlier designed to specifically account for intermolecular interactions between the components of a mixture and applied successfully to the prediction of infinite-dilution activity coefficients using neural networks (part 1 of this series). We obtain a significant QSPR model for the prediction of excess molar volume (V(E) ) using consensus neural networks and five mixture descriptors. We find that hydrogen bond and thermodynamic descriptors are the most important in determining excess molar volume (V(E) ), which is in line with the theory of intermolecular forces governing excess mixture properties. The results also suggest that the mixture descriptors utilized herein may be sufficient to model a wide variety of properties of binary and possibly even more complex mixtures.

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

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

    On May 22, 1997, DOE published a Notice of Intent (NOI) in the Federal Register (62 Federal Register 28009) announcing its decision to prepare an environmental impact statement (EIS) that would tier from the analysis and decisions reached in connection with the Storage and Disposition of Weapons-Usable Fissile Materials Final Programmatic EIS (Storage and Disposition PEIS). DOE's disposition strategy allows for both the immobilization of surplus plutonium and its use as mixed oxide (MOX) fuel in existing domestic, commercial reactors. The disposition of surplus plutonium would also involve disposal of the immobilized plutonium and MOX fuel (as spent nuclear fuel) in a geologic repository. The Surplus Plutonium Disposition Environmental Impact Statement analyzes alternatives that would use the immobilization approach (for some of the surplus plutonium) and the MOX fuel approach (for some of the surplus plutonium); alternatives that would immobilize all of the surplus plutonium; and the No Action Alternative. The alternatives include three disposition facilities that would be designed so that they could collectively accomplish disposition of up to 50 metric tons (55 tons) of surplus plutonium over their operating lives: (1) the pit disassembly and conversion facility would disassemble pits (a weapons component) and convert the recovered plutonium, as well as plutonium metal from other sources, into plutonium dioxide suitable for disposition; (2) the immobilization facility would include a collocated capability for converting nonpit plutonium materials into plutonium dioxide suitable for immobilization and would be located at either Hanford or SRS. DOE has identified SRS as the preferred site for an immobilization facility; (3) the MOX fuel fabrication facility would fabricate plutonium dioxide into MOX fuel. This volume includes background information; purpose of and need for the proposed action; alternatives for disposition of surplus weapons useable plutonium; and

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

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

    While each of the three different screening comparisons made in this report (i.e., within-medium evaluation, between-media evaluation and relative importance grouping) individually provides information potentially of value in focusing future studies, each one is subject to a variety of limitations, the most important being associated with the absence or variable quality of environmental data for a number of the contaminants and media. These screening exercises are intended to provide an initial framework for approaching the study of an extremely complex site. Other approaches could very well yield somewhat different priorities, and the identification or reinterpretation of data in subsequent detailed studies are likely to invalidate some of the results of these screening exercises. However, these evaluations provide a logical approach to defining initial off- site health impact study priorities for the ORR. Therefore, while care must be taken in attempting to make any broad generalizations or greatly simplifying assumptions with regard to the potential health hazards posed by the complex releases from the Reservation, Table 6-1 represents an attempt to summarize a set of recommendations that are derived from the screening exercises presented in this report. Table 6-1 identifies the facilities, processes and contaminants believed to have the highest potential for resulting in off-site health impacts. Table 6-2 identifies contaminants for which no ranking could be performed as part of this feasibility study, because of the absence of any appropriate data for any environmental medium

    A significant number of information sources have been identified that are relevant to historical locations and activities of populations potentially affected by releases from the Oak Ridge Reservation. The information that has been reviewed as part of this Task 5 investigation has shown that numerous residences and farms have historically been present near the ORR boundary and that a variety of land uses and recreational activities have been practiced. Based on this information alone, it would appear that many routes of off-site exposure could have been plausible. Most of the available published information addresses demographic and land use data on a regional or county-wide basis over fairly broad time periods. The information sources that are most readily available do not support direct evaluation of potential exposure pathways at specific geographic locations near the Oak Ridge facilities at specific points in time. A number of information sources have been identified that can provide demography and land use information more specific to locations and time periods that are identified to be of interest. Examples of data sources in this category include individual USGS topographic maps, aerial photographs, lowest-level census tract data, and interviews with long-time local residents. However, specific release events and periods of interest should be identified prior to attempts to collect more specific demographic or land use information for actual dose reconstruction

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

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

    The overall task of this program was to provide an assessment of currently available technology for treating commercial low-level radioactive waste (LLRW), to initiate development of a methodology for choosing one technology for a given application, and to identify research needed to improve current treatment techniques and decision methodology. The resulting report is issued in four volumes. Volume 3 of this series is a collection of abstracts of most of the reference documents used for this study. Because of the large volume of literature, the abstracts have been printed in two separate parts. Federal, state, and local regulations affect the decision process for selecting technology applications. Regulations may favor a particular technology and may prevent application of others.

    2011-01-01

    Full Text Available En este artículo, el autor analiza algunas de las preguntas clave para entender el complicado panorama internacional actual. ¿Estados Unidos ejerce a nivel internacional, durante la primera década del siglo xxi, la función de hegemonía o la de dominio?, ¿se pueden seguir negociando las diferencias y conflictos a partir de las reglas sancionadas por el derecho internacional actual?, o, por el contrario, ¿es menester ajustar las reglas del juego a nivel nacional y mundial y modificarlas sustancialmente? En este contexto, el autor indaga las razones de la pérdida de hegemonía norteamericana y su sustitución por el dominio ejercido a nivel internacional. Aborda también el papel económico y político de otros países y su impacto en la arena internacional dentro de los marcos actuales de crisis económica y política en buena parte del mundo.

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

    Full Text Available Bacillus thuringiensis-based insecticides are the main production line of the biopesticides world market. The research devoted to this area, promoted by the necessity to solve problems in agriculture and public health has resulted in an exhaustive knowledge of its biology. The diversity of the B. thuringiensis strains has permitted to develop several products mainly, but not exclusively, for insect control. With the new developments in the field of molecular biology, it has been possible to understand the molecular basis of the mode of action and to increase the range of activity as well. As a result of the broad use in several countries, resistant strains of some of the susceptible insects have appeared. The aim of this review is to elaborate a theoretical framework of the current state of research on B. thuringiensis, describing briefly the knowledge on this bacterium, with emphasis on biological phenomena that underlie its toxic activity and the problems that will be faced during the XXI century with the increasingly common resistance, all this analyzed from a biotechnological perspective.

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

    2008-12-19

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

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

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

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

    Años atrás, cuando se perfilaba el nombramiento de un nuevo Ministro de Salud, la Academia dirigió una carta al Presidente de la República que fue desatendida totalmente.

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

Para ello se caracteriza, en términos generales, el concepto de mercadotecnia, así como, la evolución de la misma desde sus inicios. Posteriormente se consideran los cambios tecnológicos, sociales y de mercado que han surgido en los inicios del milenio, para finalmente identificar las tendencias y desafíos a los cuales se enfrentan las organizaciones. Con la finalidad de recopilar la información se realizó una revisión bibliográfica y documental. Se concluye que las tendencias de la mercadotecnia se orientan al abandono del pensamiento de masas a favor de una participación individualizada con los clientes, en la cual se les trate de una forma muy personal, reconociendo sus intereses y necesidades y creándose un vínculo permanente que no sólo promueva las ventas presentes sino que garantice las ventas futuras de la compañía. Asimismo el estudio reveló que entre los retos más importantes a los que se tienen que enfrentar las organizaciones, están la globalización, la cambiante economía mundial, el auge de la tecnología de la información y la exigencia de una mayor responsabilidad ética y social, lo que implica la necesidad de darle un valor agregado al producto que siga siendo atractiva para el mercado.

    Neuroimaging studies have shown that having an extra X chromosome is associated with abnormal structure and function of brain areas in the frontal lobe, which is crucially involved in executive functioning. However, there is little of knowledge of the type and severity of executive dysfunction, and the impact on emotional and behavioral problems. The present study aims to provide in this. In total, 40 children (23 boys with 47,XXY and 17 girls with 47,XXX) with an extra X chromosome and 100 non-clinical controls (47 boys and 53 girls) participated in the study. The participants were 9-18 years old. Processing speed and executive functioning were assessed using the Amsterdam Neuropsychological Testbattery (ANT) and the Dysexecutive Questionnaire (DEX). Problems in emotional and behavioral functioning were assessed with the Childhood Behavior Checklist (CBCL). Children with an extra X chromosome showed deficits in inhibition, mental flexibility, sustained attention and visual working memory. Parental report showed high levels of everyday manifestations of executive dysfunction. More severe inhibition difficulties were associated with higher levels of thought problems, aggression and rule breaking behavior. Boys and girls with an extra X chromosome could not be differentiated based on severity of executive dysfunction, however, girls had lower information processing speed than boys. These findings suggest that executive dysfunction may be part of the phenotype of children with an extra X chromosome, impacting the ability to function adequately in everyday life. Furthermore, children with impairments in inhibition may have more problems in regulating their thinking, emotions and behavior. © 2015 John Wiley & Sons Ltd and International Behavioural and Neural Genetics Society.

A partir del supuesto de que elconductismo no es una teoría unificada de la psicología, sino una filosofía de esta disciplina, se presentan los tópicos sobrelos cuales hay mayor coincidencia entre los conductistas, a saber, la idea de que la psicología es una ciencia natural, que esuna ciencia empírica, que intenta generar un conocimiento en el que se controlen los sesgos subjetivistas (objetividad yfinalmente que utiliza en la tarea investigativa de forma preferente la metodología experimental. Se señalan igualmentealgunos tópicos sobre los cuales hay debate entre los conductistas, tales como el nivel de molecularidad o molaridad en elanálisis, la necesidad o no de factores mediadores y el uso de la investigación ideográfica vs la investigación nomotética.El trabajo concluye señalando cómo algunos de los conceptos más conocidos como «estímulo», «respuesta»,«condicionamiento» entre otros, no son esenciales al conductismo y eventualmente podrían ser reemplazados por otros.ABSTRACTA conceptual review of Behaviorism is presented in which its main features are discussed with the purpose of assessingits viability as a proposal for the XXIth century.

    To evaluate the changes in beverage consumption among adolescents between 2003 and 2008. Two school-based cross-sectional studies were carried out with public school students (12 to 19 years-old) from Niterói, Rio de Janeiro, Brazil. Data from three food records were used to estimate daily, weekdays and weekend average consumption (volume and percent contribution for total daily energy intake) of milk and milk-based beverages, sugar sweetened beverages, fresh squeezed fruit juices, caffeinated and alcoholic beverages. Beverage consumption age-adjusted means for weekdays and weekends were compared using linear regression (Generalized Linear Models - GLM). A total of 433 adolescents were examined in 2003, and 510 in 2008. The prevalence of overweight was 17% in 2003 and 22% in 2008 (p > 0.05). Milk was the most consumed beverage, being reported by 89% of adolescents, followed by sodas (75%). In general, in the five-year period, there was an increase in the prevalence of consumption of alcoholic drinks, guarana syrup refreshment, and processed fruit drinks, especially on weekdays. The soft drink was the largest contributor to the total energy consumption, corresponding on average to 4% of daily energy intake. The main changes in the beverage consumption among adolescents from Niterói, in the first decade of the XXI century, were the tendency to reduce the consumption of milk and the increase in the consumption of processed and alcoholic beverages.

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

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

    Background Fat grafting has become increasingly popular for the correction of soft tissue deficits at many sites throughout the body. Long-term outcomes, however, depend on delivery of fat in the least traumatic fashion to optimize viability of the transplanted tissue. In this study, we compare the biologic properties of fat following injection using two methods. Methods Lipoaspiration samples were obtained from five female donors and cellular viability, proliferation, and lipolysis were evaluated following injection using either a modified Coleman technique or an automated, low shear device. Comparisons were made to minimally processed, uninjected fat. Volume retention was also measured over twelve weeks following injection of fat under the scalp of immunodeficient mice using either the modified Coleman technique or the Adipose Tissue Injector. Finally, fat grafts were analyzed histologically. Results Fat viability and cellular proliferation were both significantly greater with the Adipose Tissue Injector relative to injection with the modified Coleman technique. In contrast, significantly less lipolysis was noted using the automated device. In vivo fat volume retention was significantly greater than with the modified Coleman technique at 4, 6, 8, and 12 week time points. This corresponded with significantly greater histological scores for healthy fat and lower scores for injury following injection with the device. Conclusions Biological properties of injected tissues reflect how disruptive and harmful techniques for placement of fat may be, and our in vitro and in vivo data both support the use of the automated, low shear devices compared to the modified Coleman technique.

    The conversion of 3 H-testosterone and the uptake of 3 H-testosterone and 3 H-5α-dihydrotestosterone were investigated in pubic skin and pubic hair follicles of a XXY-man with inadequate pubic hair. The uptake of both androgens was demonstrated in the skin as well as in the hair follicles. Similarly the activity of steroid 5α-reductase was present in both tissues. The total conversion of 3 H-testosterone was 2-3 times higher in the patient than in control persons. In the XXY-man the major metabolites were 5α- and 5β-androstanediols, whereas in the normal men 5α-dihydrotestosterone and 4-androstenedione were mainly formed from testosterone. An explanation of the inadequate growth of pubic hair in our patient seems to be related to a conversion of testosterone - at its low plasma level - to its relatively inactive metabolites. (author)

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

    El siglo XXI es testigo de una transformación en el concepto de ocio, con un importante aumento de sus actividades con transcendencia económica. Hasta ahora el ocio se consideraba en los períodos de no trabajo y hoy se buscan experiencias importantes a lo largo de todo la vida. El Instituto de Estudios de Ocio de la Universidad de Deusto centra su interés en la experiencia humana más allá de los productos tangibles. Asistimos a un cambio cultural importante en el mundo desarrollado donde la mayor parte de la población se ha volcado en una filosofía que se podría resumir como “tener menos, disfrutar más”. Paralelamente, las TIC’s han propiciado una revolución en el campo del ocio: el ocio digital con manifestaciones como los videojuegos o las comunidades virtuales. Todo ello se traduce en un importante impacto económico en términos de generación de producción, empleo y renta que tratamos de abordar en este artículo.

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

    2016-02-01

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

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

    1979-01-01

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

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

This has forced in certain moments to introduce norms in order to get an attractive game that responds to the complex demands of the marketing and sale of the product. Handball, though a relatively young sport, can not be far from the competitive market, sport promotion, the television, media, spectators, etc. Professionalization was the best way to improve habits in favor of the show. Specialists, managers of elite players and those  new to the game,  should not forget the roots, the bases and the historical evolution of the offensive aspect of this sport. The knowledge of these should be good to contribute creative ideas that enrich, if it's possible the dynamism, intelligence and competitiveness of handball.   This article is a review of  the  work published  in the volume two of this journal,  “The beginnings of the XXI century: evolution and tendencies of the game”.

    The U.S. Department of Energy (DOE) is considering the possible recommendation of a site at Yucca Mountain, Nevada, for development as a geologic repository for the disposal of high-level radioactive waste and spent nuclear fuel. To facilitate public review and comment, in May 2001 the DOE released the Yucca Mountain Science and Engineering Report (S and ER) (DOE 2001 [DIRS 153849]), which presents technical information supporting the consideration of the possible site recommendation. The report summarizes the results of more than 20 years of scientific and engineering studies. A decision to recommend the site has not been made: the DOE has provided the S and ER and its supporting documents as an aid to the public in formulating comments on the possible recommendation. When the S and ER (DOE 2001 [DIRS 153849]) was released, the DOE acknowledged that technical and scientific analyses of the site were ongoing. Therefore, the DOE noted in the Federal Register Notice accompanying the report (66 FR 23 013 [DIRS 155009], p. 2) that additional technical information would be released before the dates, locations, and times for public hearings on the possible recommendation were announced. This information includes: (1) the results of additional technical studies of a potential repository at Yucca Mountain, contained in this FY01 Supplemental Science and Performance Analyses: Vol. 1, Scientific Bases and Analyses; and FY01 Supplemental Science and Performance Analyses: Vol. 2, Performance Analyses (McNeish 2001 [DIRS 155023]) (collectively referred to as the SSPA) and (2) a preliminary evaluation of the Yucca Mountain site's preclosure and postclosure performance against the DOE's proposed site suitability guidelines (10 CFR Part 963 [64 FR 67054] [DIRS 124754]). By making the large amount of information developed on Yucca Mountain available in stages, the DOE intends to provide the public and interested parties with time to review the available materials and to formulate

    One-third of patients with an exacerbation of Chronic Obstructive Pulmonary Disease(COPD) are re-hospitalised at 90 days. Exacerbation recovery is associated with reductions in lung hyperinflation and improvements in symptoms and physical activity. We assessed the feasibility of monitoring these clinical parameters in the home. We hypothesised that the degree of change in spirometry and lung volumes differs between those who had an uneventful recovery and those who experienced a further exacerbation. Hospitalised patients with an acute exacerbation of COPD referred for a supported discharge program participated in the study. Spirometry and Inspiratory Vital Capacity(IVC) were measured in the home at Days 1, 14 and 42 post-discharge. Patients also completed Medical Research Council(MRC), Borg and COPD Assessment Test(CAT) scores and were provided with a tri-axial accelerometer. Any new exacerbation events were recorded. Sixty-five patients with 72 exacerbation episodes were recruited. Fifty percent experienced a second exacerbation. Adequate IVC measurements were achieved by 90%, while only 70% completed spirometry. Uneventful recovery was accompanied by significant improvements in physiological measurements at day14, improved symptom scores and step count, p volumes, symptoms and step count following a COPD exacerbation may help to identify patients at risk of re-exacerbation. It is feasible to carry out these assessments in the home as part of a supported discharge programme. Copyright © 2016 Elsevier Ltd. All rights reserved.

    noted that this year's conference included a noticeably larger number of reports on astrophysical applications and physics of planetary atmospheres. Another significant trend was related to a new area of inquiry: low temperature spectra, near-surface processes, and control and management of new technological processes. There were more presentations on elementary processes during the formation of spectral lines. Most of the presented studies were included in the Conference Proceedings publication. For the first time ever the proceedings will be published as a volume of Journal of Physics: Conference Series, published by the Institute of Physics (UK), making it possible to access the materials of the conference online. All published studies underwent peer review. The organizers would like to thank all the reviewers who found time to review the submissions against a very tight deadline during the summer. Professor N G Skvortsov, Vice-Rector for Research of St Petersburg State University, opened the conference. His speech was followed by a brief welcome message from Professor A Devdariani of St Petersburg State University, Deputy Chair of the Organizing Committee.

    Ovotesticular disorder of sexual development (DSD) is characterized by the presence of both ovarian and testicular tissues in the same individual. The most common karyotype is 46,XX. Here, we report the case of a boy with a 46,XX/47,XXY karyotype diagnosed as ovotesticular DSD by gonadal biopsy. A 5-month-old boy presented with hypospadias, unilateral cryptorchidism, and a micropenis. Pelvic magnetic resonance imaging revealed a suspicious gonad tissue that is solid in structure in the right scrotum and a suspicious gonad that is cystic in structure in the left inguinal canal. He underwent a diagnostic laparoscopy. Cytogenetic analysis of peripheral blood revealed a 46,XX/47,XXY karyotype. Histopathologic examination of the left gonad showed ovarian tissue containing primordial follicles with ipsilateral undifferentiated tuba uterina. The right gonad showed immature testis tissue. He underwent left gonadectomy and hypospadias repair, and was raised as a male. Through this rare case, we highlight the importance of histological and cytogenetic investigation in DSD.

    47 XXY/46 XX mosaicism with characteristics suggesting Klinefelter syndrome is very rare and at present, only seven cases have been reported in the literature. We report an Indian boy diagnosed as variant of Klinefelter syndrome with 47 XXY/46 XX mosaicism at age 12 years. He was noted to have right cryptorchidism and chordae at birth, but did not have surgery for these until age 3 years. During surgery, the right gonad was atrophic and removed. Histology revealed atrophic ovarian tissue. Pelvic ultrasound showed no Mullerian structures. There was however no clinical follow up and he was raised as a boy. At 12 years old he was re-evaluated because of parental concern about his 'female' body habitus. He was slightly overweight, had eunuchoid body habitus with mild gynaecomastia. The right scrotal sac was empty and a 2mls testis was present in the left scrotum. Penile length was 5.2 cm and width 2.0 cm. There was absent pubic or axillary hair. Pronation and supination of his upper limbs were reduced and x-ray of both elbow joints revealed bilateral radioulnar synostosis. The baseline laboratory data were LH XX[67] with SRY positive. Laparoscopic examination revealed no Mullerian structures. Insisting on an adequate number of cells (at least 50) to be examined during karyotyping is important so as not to miss diagnosing mosaicism.

    Cinema Metropole XXI is one of the heritage buildings located in the heart of Menteng area, with “art deco” architecture. The appereance of this building is very beautiful and very impressed from other buildings, become strong Icon around the Menteng neighborhood. In 2010 the building was bought by Cinema 21, where the physical condition is very messy and looks slum. The emergence of modern shopping and entertainment centers are also complete with cinema facilities are more comfortable and complete, While the atmosphere of this old cinema is considered uncomfortable for visitors, so slowly abandoned by customers. The status of the cultural heritage inherent in this building becomes an obstacle by owners to renew this building, until the cinema closes in some time. The loss of the long-standing potential of cultural heritage buildings due to the transformation of urban development is an important issue in this paper, this case study is the author’s experience in regenerating the future potential at this heritage building. This writing is done by Descriptive Analysis method from various reference approaches and theory of cultural heritage values involved in the restoration of Metropole XXI cinema. The conclusions of this paper find a real solution to problem solving for the sustainability of this building.

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

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

  4. Discussion about the use of the volume specific surface area (VSSA) as a criterion to identify nanomaterials according to the EU definition. Part two: experimental approach.

    The first part of this study was dedicated to the modelling of the influence of particle shape, porosity and particle size distribution on the volume specific surface area (VSSA) values in order to check the applicability of this concept to the identification of nanomaterials according to the European Commission Recommendation. In this second part, experimental VSSA values are obtained for various samples from nitrogen adsorption isotherms and these values were used as a screening tool to identify and classify nanomaterials. These identification results are compared to the identification based on the 50% of particles with a size below 100 nm criterion applied to the experimental particle size distributions obtained by analysis of electron microscopy images on the same materials. It is concluded that the experimental VSSA values are able to identify nanomaterials, without false negative identification, if they have a mono-modal particle size, if the adsorption data cover the relative pressure range from 0.001 to 0.65 and if a simple, qualitative image of the particles by transmission or scanning electron microscopy is available to define their shape. The experimental conditions to obtain reliable adsorption data as well as the way to analyze the adsorption isotherms are described and discussed in some detail in order to help the reader in using the experimental VSSA criterion. To obtain the experimental VSSA values, the BET surface area can be used for non-porous particles, but for porous, nanostructured or coated nanoparticles, only the external surface of the particles, obtained by a modified t-plot approach, should be considered to determine the experimental VSSA and to avoid false positive identification of nanomaterials, only the external surface area being related to the particle size. Finally, the availability of experimental VSSA values together with particle size distributions obtained by electron microscopy gave the opportunity to check the

    International Nuclear Information System (INIS)

    2008-01-01

    ISO 18213 deals with the acquisition, standardization, analysis, and use of calibration to determine liquid volumes in process tanks for the accountancy of nuclear materials. This part of ISO 18213 is complementary to the other parts, ISO 18213-1 (procedural overview), ISO 18213-2 (data standardization), ISO 18213-3 (statistical methods), ISO 18213-5 (fast bubbling rate) and ISO 18213-6 (in-tank determination of liquid density). The procedure presented herein for determining liquid height from measurements of induced pressure applies specifically when a very slow bubbling rate is employed. A similar procedure that is appropriate for a fast bubbling rate is given in ISO 18213-5. Measurements of the volume and height of liquid in a process accountancy tank are often made in order to estimate or verify the tank's calibration or volume measurement equation. The calibration equation relates the response of the tank's measurement system to some independent measure of tank volume. Beginning with an empty tank, calibration data are typically acquired by introducing a series of carefully measured quantities of some calibration liquid into the tank. The quantity of liquid added, the response of the tank's measurement system, and relevant ambient conditions such as temperature are measured for each incremental addition. Several calibration runs are made to obtain data for estimating or verifying a tank's calibration or measurement equation. A procedural overview of the tank calibration and volume measurement process is given in ISO 18213-1. An algorithm for standardizing tank calibration and volume measurement data to minimize the effects of variability in ambient conditions that prevail during the measurement period is given in ISO 18213-2. The procedure presented in this part of ISO 18213 for determining the height of calibration liquid in the tank from a measurement of the pressure it induces in the tank's measurement system is a vital component of that algorithm.

    Full Text Available In the paper, the author briefly presents possible global and regional evolutions of geopolitics in the XXI century grounded on the analysis of some regards expressed by foreign and Romanian specialists in many papers appeared in the late years on this subject. A special attention is granted to the book published by STRATFOR founder George FRIEDMAN “The Next 100 Years: A Forecast for the 21st Century”, edited in Romania to the Litera Publishing House in 2012. The evolutions forecasted on medium and long term will practically damage all Earth’s population and its regions, with dramatic consequences on economic, financial, social, military and environmental plan. The most of the geopolitics’ specialists appreciate with arguments and grounded there will be following intricate decades with riots and wars with spectacular up side downs of situations and major reconfigurations of areas of influence of major powers with important influences also over Romania.

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

    The Interface Region Imaging Spectrometer (IRIS) is the first solar instrument to observe ∼10 MK plasma at subarcsecond spatial resolution through imaging spectroscopy of the Fe XXI λ1354.1 forbidden line. IRIS observations of the X1 class flare that occurred on 2014 March 29 at 17:48 UT reveal Fe XXI emission from both the flare ribbons and the post-flare loop arcade. Fe XXI appears at all of the chromospheric ribbon sites, although typically with a delay of one raster (75 s) and sometimes offset by up to 1''. 100-200 km s{sup –1} blue-shifts are found at the brightest ribbons, suggesting hot plasma upflow into the corona. The Fe XXI ribbon emission is compact with a spatial extent of <2'', and can extend beyond the chromospheric ribbon locations. Examples are found of both decreasing and increasing blue-shift in the direction away from the ribbon locations, and blue-shifts were present for at least six minutes after the flare peak. The post-flare loop arcade, seen in Atmospheric Imaging Assembly 131 Å filtergram images that are dominated by Fe XXI, exhibited bright loop-tops with an asymmetric intensity distribution. The sizes of the loop-tops are resolved by IRIS at ≥1'', and line widths in the loop-tops are not broader than in the loop-legs suggesting the loop-tops are not sites of enhanced turbulence. Line-of-sight speeds in the loop arcade are typically <10 km s{sup –1}, and mean non-thermal motions fall from 43 km s{sup –1} at the flare peak to 26 km s{sup –1} six minutes later. If the average velocity in the loop arcade is assumed to be at rest, then it implies a new reference wavelength for the Fe XXI line of 1354.106 ± 0.023 Å.

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

    To investigate the structural effect of polymeric excipients on the behavior of free volume of drug-polymer dispersions in relation to glass transition. Two drugs (indomethacin and ketoconazole) were selected to prepare amorphous dispersions with PVP, PVPVA, HPC, and HPMCAS through spray drying. The physical attributes of the dispersions were characterized using SEM and PXRD. The free volume (hole-size) of the dispersions along with drugs and polymers was measured using positron annihilation lifetime spectroscopy (PALS). Their glass transition temperatures (Tgs) were determined using DSC and DMA. FTIR spectra were recorded to identify hydrogen bonding in the dispersions. The chain structural difference-flexible (PVP and PVPVA) vs. inflexible (HPC and HPMCAS)-significantly impacts the free volume and Tgs of the dispersions as well as their deviation from ideality. Relative to Tg, free volume seems to be a better measure of hydrogen bonding interaction for the dispersions of PVP, HPC, and HPMCAS. The free volume of polymers and their dispersions in general appears to be related to their conformations in solution. Both the backbone chain rigidity of polymers as well as drug-polymer interaction can impact the free volume and glass transition behaviors of the dispersions.

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

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

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

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

    Bernardo Caprara

    Full Text Available Resumo O tema da desigualdade tem uma larga tradição de análise nas Ciências Sociais. Até o final do século XX, a desigualdade econômica ocupava boa parte dessas discussões. De lá para cá, as desigualdades passaram a ser vistas como multidimensionais, mas permanece relevante o estudo da distribuição desigual de renda, riqueza e capital. A obra "O Capital no Século XXI", do economista francês Thomas Piketty, publicada em 2013, na França, e em 2014, no Brasil, envereda por esse caminho e ilumina novas indagações sobre a atualidade e os rumos da desigualdade econômica. Esta resenha crítica objetiva apresentar as principais contribuições do autor para o debate público e acadêmico. Além disso, ambiciona refletir sobre uma agenda para a Sociologia atual, desde a importância de entender como ocorre a gênese e a legitimação da reprodução das desigualdades de oportunidades no nosso tempo.

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

    The overall task of this program was to provide an assessment of currently available technology for treating commercial low-level radioactive waste (LLRW), to initiate development of a methodology for choosing one technology for a given application, and to identify research needed to improve current treatment techniques and decision methodology. The resulting report is issued in four volumes. Volume 3 of this series is a collection of abstracts of most of the reference documents used for this study. Because of the large volume of literature, the abstracts have been printed in two separate parts. Volume 3, part 1 presents abstracts of the open literature relating to LLRW treatment methodologies. Some of these references pertain to treatment processes for hazardous wastes that may also be applicable to LLRW management.

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

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

    Mastery of employability skills is one of the main characteristics of HR XXI Century. The conclusions of various theoretical and empirical studies show that human resources with high employability skills are not only easier to find a job but will also be able to exist and develop successfully in their work. This study aims to describe the opinion of the industry leaders about the importance of employability skills owned by SMK graduates, to identify the various values of employability skills that the industry needs from SMK graduates, and categorize the values of employability skills that SMK graduates should have. A total of 27 industries partner of SMK in East Java were involved in survey research and 14 productive teachers from seven SMKs were included in the FGD on employability skills development. The results showed that (1) all industry leaders argue that the graduates of SMK must have good employability skills, (2) dimensions of employability skills include the fundamental skills, personal management skills, and team work skills; and (3) the ownership of various values of employability skills by SMK graduates can be classified into two, namely (a) must be owned and should be developed in SMK, and (b) well owned and better developed in SMK.

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

  12. Cyberwar XXI: quantifying the unquantifiable: adaptive AI for next-generation conflict simulations

    Science.gov (United States)

    Miranda, Joseph; von Kleinsmid, Peter; Zalewski, Tony

    2004-08-01

    The era of the "Revolution in Military Affairs," "4th Generation Warfare" and "Asymmetric War" requires novel approaches to modeling warfare at the operational and strategic level of modern conflict. For example, "What if, in response to our planned actions, the adversary reacts in such-and-such a manner? What will our response be? What are the possible unintended consequences?" Next generation conflict simulation tools are required to help create and test novel courses of action (COA's) in support of real-world operations. Conflict simulations allow non-lethal and cost-effective exploration of the "what-if" of COA development. The challenge has been to develop an automated decision-support software tool which allows competing COA"s to be compared in simulated dynamic environments. Principal Investigator Joseph Miranda's research is based on modeling an integrated military, economic, social, infrastructure and information (PMESII) environment. The main effort was to develop an adaptive AI engine which models agents operating within an operational-strategic conflict environment. This was implemented in Cyberwar XXI - a simulation which models COA selection in a PMESII environment. Within this framework, agents simulate decision-making processes and provide predictive capability of the potential behavior of Command Entities. The 2003 Iraq is the first scenario ready for V&V testing.

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

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

    Projection of regional climate changes for XXI century is one of the priorities of EC environmental programme. Potential worsening of the waves' statistics, sea level rise and extreme surges are the principal negative consequences of the climate change for marine environment. That is why the main purpose of this presentation is to discuss the above issue for the Black sea region (with a strong focus to the south-west subregion because the maximum heights of waves exceeding 10 m occur just here) using output of several global coupled models (GCM) for XXI century, wave simulation, long-term observations of sea level and statistical techniques. First of all we tried to choose the best coupled model (s) simulated the Black sea climate change and variability using the control experiments for 20 century (203). The principal result is as follows. There is not one model which is simulating adequately even one atmospheric parameter for all seasons. Therefore we considered (for the climate projection) different outputs form various models. When it was possible we calculated also the ensemble mean projection for the selected model (s) and emission scenarios. To calculate the wave projection we used the output of SWAN model forced by the GCM wind projection for 2010 to 2100. To estimate the sea level rise in XXI century and future surges statistics we extrapolate the observed sea level rise tendencies, statistical relation between wave heights and sea level and wave scenarios. Results show that in general, the climate change in XXI century doesn't lead to the catastrophic change of the Black sea wind-wave statistics including the extreme waves in the S-W Black sea. The typical atmospheric pattern leading to the intense storm in the S-W Black sea is characterized by the persistent anticyclonic area to the North of the Black sea and cyclonic conditions in the Southern Black sea region. Such pressure pattern causes persistent and strong eastern or north-eastern wind which

  3. Acid-base titrations by stepwise addition of equal volumes of titrant with special reference to automatic titrations-III Presentation of a fully automatic titration apparatus and of results supporting the theories given in the preceding parts.

    Science.gov (United States)

    Pehrsson, L; Ingman, F

    1977-02-01

    This paper forms Part III of a series in which the first two parts describe methods for evaluating titrations performed by stepwise addition of equal volumes of titrant. The great advantage of these methods is that they do not require an accurate calibration of the electrode system. This property makes the methods very suitable for routine work. e.g., in automatic analysis. An apparatus for performing such titrations automatically is presented. Further, results of titrations of monoprotic acids, a diprotic acid, an ampholyte, a mixture of an acid with its conjugate base, and mixtures of two acids with a small difference between the stability constants are given. Most of these titrations cannot be evaluated by the Gran or Hofstee methods but yield results having errors of the order of 0.1% if the methods proposed in Parts I and II of this series are employed. The advantages of the method of stepwise addition of equal volumes of titrant combined with the proposed evaluation methods, in comparison with common methods such as titration to a preset pH, are that all the data are used in the evaluation, permitting a statistical treatment and giving better possibilities for tracing systematic errors.

  4. PHILOSOPHICAL-CULTURAL CONCEPTION OF TELEVISION AS A VISUAL PRACTICES OF XX-XXI CENTURY

    Directory of Open Access Journals (Sweden)

    2016-12-01

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

    Full Text Available Salud para todos en el siglo XXI renueva el compromiso con el concepto y la visión de salud para todos, tal como se definió en 1977, cuando la 30a Asamblea Mundial de la Salud resolvió que el principal objetivo social de los gobiernos y de la OMS en los decenios venideros debería ser "alcanzar para todos los ciudadanos del mundo en el año 2000 un grado de salud que les permita llevar una vida social y económicamente productiva". Este proceso, que se interpreta de forma diferente según las características sociales, económicas y de salud de cada país, ha contribuido a la mejora paulatina del acceso a la atención primaria de salud, a la disminución mundial de la morbilidad y la mortalidad infantiles y a un aumento considerable de la esperanza de vida. Aun así, todavía hay muchos problemas que resolver. Desde 1990, el sistema de las Naciones Unidas ha convocado nueve conferencias mundiales en las que se han acordado por consenso universal las prioridades de un programa de trabajo para el futuro, incluido el apoyo pleno del logro de salud para todos. Los nuevos enfoques giran en torno al desarrollo centrado en el ser humano, lo cual comprende erradicar la pobreza, satisfacer las necesidades básicas y proteger los derechos humanos, incluido el de la salud.

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

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

    The observation of the high temperature (above 10 MK) Fe XXI 1354.1 A line with the Interface Region Imaging Spectrograph (IRIS) has provided significant insights into the chromospheric evaporation process in flares. In particular, the line is often observed to be completely blueshifted, in contrast to previous observations at lower spatial and spectral resolution, and in agreement with predictions from theoretical models. Interestingly, the line is also observed to be mostly symmetric and with a large excess above the thermal width. One popular interpretation for the excess broadening is given by assuming a superposition of flows from different loop strands. In this work, we perform a statistical analysis of Fe XXI line profiles observed by IRIS during the impulsive phase of flares and compare our results with hydrodynamic simulations of multi-thread flare loops performed with the 1D RADYN code. Our results indicate that the multi-thread models cannot easily reproduce the symmetry of the line and that some other physical process might need to be invoked in order to explain the observed profiles.

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

    Full Text Available This article presents an interpretation of the recent evolution of the issue of nationality in contemporary Spain from an historical perspective, beginning with the approval of the 1978 Constitution and the ensuing implementation of the State of the Autonomous Communities at the politico-institutional level. It then goes on to examine the challenges faced by substate and state nationalisms in present-day Spain, which may be summed up in the growing plurality of sentiments of multiple belonging on the part of Spanish citizens, as well as the impact of globalization and foreign immigration. All these phenomena have transformed the conditions in which nationalisms interact, and will require0 political elites to rethink the theoretical frameworks of nationalist doctrines. | El artículo ofrece una interpretación en clave histórica de la evolución reciente de la cuestión nacional en la España contemporánea, desde la aprobación de la Constitución de 1978 y la articulación político-institucional del Estado de las Autonomías, y a continuación expone los retos a los que los nacionalismos subestatales y de Estado que conviven en territorio español se enfrentan en la primera década del siglo XXI, subrayando el hecho de que la pluralidad de opciones y pertenencias identitarias de los ciudadanos, el impacto de la globalización y de la inmigración han transformado las coordenadas básicas de la cuestión nacional y obligan a las élites a repensar los marcos teóricos de las doctrinas nacionalistas.

    Full Text Available As características da cultura e da sociedade se alteraram profundamente na medida em que novas formas de comunicação dependentes das tecnologias digitais adquiriram um uso generalizado, modificando o modo como buscamos e produzimos informação. Entretanto, as ciências sociais ainda analisam este fenômeno de maneira tímida, negligenciando os efeitos das tecnologias digitais nas sociedades e, sobretudo, no próprio ofício da sociologia. O presente artigo descreve o modo como as mudanças tecnológicas representam um dos grandes desafios para a sociologia do século XXI, argumentando que é necessário não apenas o aperfeiçoamento de aspectos tecnológicos da pesquisa - como, por exemplo, o domínio de softwares de análise qualitativa e quantitativa e de redes sociais digitais - mas, fundamentalmente, o avanço em termos do significado epistemológico destas tecnologias para a imaginação sociológica. Na primeira seção, é apresentada a proposta da sociologia digital. Em seguida, descreve-se o fenômeno da produção massiva de dados digitais e os desafios que tal contexto coloca para a sociologia. A terceira seção avalia as implicações para a sociologia do uso de softwares. A última seção defende a necessidade urgente de uma atualização teórico-metodológica da sociologia frente à produção massiva de dados digitais. Por fim, argumenta-se que a sobrevivência da sociologia dependerá da instrumentalização tecnológica aliada a uma reflexão diante de um novo horizonte de questões da era digital.

    1994-09-01

    President Clinton has directed an Interagency Working Group to initiate a comprehensive review of long-term options for the disposition of surplus plutonium. As part of this initiative, Secretary of Energy, Hazel O'Leary, has directed that a Department of Energy project be initiated to develop options and recommendations for the safe storage of these materials in the interim. A step in the process is a plutonium vulnerability assessment of facilities throughout the Department. The Plutonium Vulnerability Working Group was formed to produce the Project and Assessment Plans, to manage the assessments and to produce a final report for the Secretary by September 30, 1994. The plans established the approach and methodology for the assessment. The Project Plan specifies a Working Group Assessment Team (WGAT) to examine each of the twelve DOE sites with significant holdings of plutonium. The Assessment Plan describes the methodology that the Site Assessment Team (SAT) used to report on the plutonium holdings for each specific site.This report provides results of the assessment of the Lawrence Berkeley Laboratory

    The obtention of copper from primary resources by solvent extraction has been developed continuously over the past 25-30 years, entailing a continuous effort both of research and development and being one of the biggest successes in the industrial development of a given metal. The success of this operation was not possible without the corresponding developments, at the same time, of the two accompanying operations (leaching and electro wining), which perfectly coupled in the operational sequence. The recovery of copper by means of these hydrometallurgical processes is firmly established and being reflecting in the growing number of operational plants under construction and/or commissioned until the beginning of the XXI century. This work presents data on the successfully application of the sequence of operations on the recovery of a metal: copper (Author) 19 refs.

    1975-11-13

    The McDonough syndrome is a "new" MCA/MR syndrome which was found in 3 children (1 girl, 2 boys) of non-consanguineous parents. The affected children were mentally retarded (IQ 47--67) and had congenital heart defect, sternal deformity, kyphosis and craniofacila anomalies (anteverted auricles, upward slanted palpebral fissures, squint); cryptorchidism was present in the 2 boys. In addition a possible VFDP is postulated as the explanation for similar features in affected and unaffected siblings and parents. However, the McDonough syndrome may be an autosomal recessive trait with minor manifestations in heterozygotes. The klinefelter syndrome in one affected boy and a 46,XY/47,XXY chromosome constitution in the father was a coincidental finding.

    1996-01-01

    This EIS identifies the impacts of past, current, and potential programs of the DOE/NV. Potential programs are included in one or more of the four alternatives and fall into three basic levels: (1) current activities, (2) planned projects, and (3) proposed projects. Current activities are those that are presently part of the normal operations of the NTS, the Tonopah test Range, portions of the NAFR Complex, and other areas considered in this EIS, such as the Area 5 Radioactive Waste management Site. Planned projects are those that are within the 5-year planning cycle and are likely to be implemented, such as the Solar Enterprise Zone. Proposed projects are outside the 5-year planning window, but have undergone sufficient conceptual development to allow a reasonable assessment. The most reliable data are clearly derived from ongoing activities. Planned projects would present somewhat less reliable data. Data for proposed projects would be the least reliable, but were determined to be essential to a full and open evaluation and disclosure of the potential effects of the alternatives. To provide an adequate analysis, conservative assumptions and parameter values were used to evaluate potential impacts of the less-defined activities. Implementation of any of the alternatives could result in a permanent commitment of resources such as groundwater, soil, biota, minerals, surface area, and subsurface geology and would represent an irreversible and irretrievable commitment of such resources. In addition to the National Environmental Policy Act requirement to identify the irreversible and irretrievable commitments of resources, it is also the intent of the DOE to identify these same resources within the meaning of the Comprehensive Environmental Response, Compensation, and Liability Act

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

    Luciana Fogaça Monteiro

    2009-11-01

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

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

    Full Text Available El artículo presenta algunas de las consideraciones expuestas en una investigación efectuada en la escuela de Comunicación Social de la Universidad del Zulia, en el período julio-diciembre de 2004 cuyo objetivo fue identificar los lineamientos prospectivos a seguir en la práctica docente del área de tecnología de la información y la comunicación en el pensum de estudio de la escuela de Comunicación social de LUZ. Se parte e la necesidad de adecuar la capacidad tecnológica y de producción a las demandas y necesidades reales en la formación del comunicador social con el fin de responder, de manera satisfactoria a las dinámicas del mercado y a una sociedad que impone el uso de las tecnologías en el campo laboral. Los hallazgos plantean que la información del comunicador social no puede estar alejada de los cambios que la tecnología de la información y la comunicación impone en este siglo XXI. Tampoco se debe sobredimensionar sus características y potencialidades, pero sí reconocer los impactos que tiene sobre la profesión y la manera cómo se ha introducido aceleradamente dentro de este campo, en este sentido, muchas de las escuelas de comunicación social no han planificado la introducción de las tecnologías de la comunicación y la información en sus pensum de estudio y, por lo tanto, no hay una combinación de saberes fundamentales y aplicados y diferenciados en el proceso instruccional y en el modelo curricular, que le da organicidad de criterios y responda a las exigencias del mercado laboral, a las expectativas de los estudiantes, de los egresados y a la función misma de la universidad orientada al desarrollo completo de los individuos en sus relaciones con la sociedad, el mundo y la vida.

    International Nuclear Information System (INIS)

    2008-01-01

    ISO 18213 deals with the acquisition, standardization, analysis, and use of calibration data to determine liquid volumes in process tanks for accountability purposes. This part of ISO 18213 is complementary to the other parts, ISO 18213-1 (procedural overview), ISO 18213-2 (data standardization), ISO 18213-3 (statistical methods), ISO 18213-4 (slow bubbling rate), ISO 18213-5 (fast bubbling rate). The procedure described in this part of ISO 18213 is a two-step procedure. First, a liquid of known density is used to determine the vertical distance between the tips of the two probes (i.e. to calibrate their separation). The calibration step requires synchronous (or as nearly synchronous as possible) measurements of the pressure exerted at the tips of two probes by the calibration liquid in which they are submerged. The measurements obtained are used to make an accurate determination of probe separation. Second, the unknown density of the process liquid is determined with the aid of the probe separation calibration. The density-determination step also requires (nearly) synchronous measurements of the pressure exerted at the tips of two probes by the process liquid of unknown density. With careful technique, it is possible to make determinations of liquid density with in-tank measurements that approach the accuracy and precision of those made in the laboratory. Moreover, density determinations made with in-tank measurements are automatically made at the observed temperature of the tank liquid. Thus, no additional information about the liquid is required to infer its density at its tank temperature from determinations of its density at some other temperature. Except that the density of the process liquid is generally not well characterized, the steps involved in determining the height of process liquid in the tank are the same as those for determining the height of calibration liquid. Thus, the method of density determination given in this part of ISO 18213 is very

    Full Text Available El artículo caracteriza las condiciones de la oferta informal de suelo y vivienda durante la primera década del siglo xxi en Bogotá, en cuanto a magnitud y localización del crecimiento de la urbanización informal (nuevos asentamientos en la periferia y densificación informal de áreas consolidadas, condiciones habitacionales de viviendas en ocupaciones recientes y las características de funcionamiento en términos de mercado del suelo. El panorama de la última década se reconstruyó con base en análisis de aerofotografías, cuantificación de datos censales y análisis de datos de las entidades de planificación y control a la urbanización informal. Los resultados sugieren que debido al agotamiento relativo del suelo en Bogotá, entre otros aspectos, las dinámicas a partir de las cuales opera el mercado informal han experimentado cambios frente a décadas anteriores, pues el crecimiento en densificación de asentamientos en la ciudad consolidada cobra mayor importancia relativa frente al desarrollo informal en las periferias, pero a la vez se intuye una expansión de la informalidad que trasciende el perímetro distrital.

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

    Mutations of the cyclin-dependent kinase-like 5 gene (CDKL5), reported almost exclusively in female subjects, have been recently found to be the cause of a phenotype overlapping Rett syndrome with early-onset epileptic encephalopathy. We describe the first CDKL5 mutation detected in a male individual with 47,XXY karyotype. This previously unreported, de novo, mutation truncates the large CDKL5 COOH-terminal region, thought to be crucial for the proper sub-cellular localization of the CDKL5 protein. The resulting phenotype is characterized by a severe early-onset epileptic encephalopathy, global developmental delay, and profound intellectual and motor impairment with features reminiscent of Rett syndrome. In light of the data presented we discuss the possible phenotypic modulatory effects of the supernumerary wild type X allele and pattern of X chromosome inactivation and stress the importance of considering the causal involvement of CDKL5 in developmentally delayed males with early-onset seizures.

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

    2016-01-01

    The book presents pedagogical reviews of important topics on high energy physics to the students and researchers in particle physics. The book also discusses topics on the Quark–Gluon plasma, thermal field theory, perturbative quantum chromodynamics, anomalies and cosmology. Students of particle physics need to be well-equipped with basic understanding of many concepts underlying the standard models of particle physics and cosmology. This is particularly true today when experimental results from colliders, such as large hadron collider (LHC) and relativistic heavy ion collider (RHIC), as well as inferences from cosmological observations, are expected to further expand our understanding of particle physics at high energies. This volume is the second in the Surveys in Theoretical High Energy Physics Series (SThEP). Topics covered in this book are based on lectures delivered at the SERC Schools in Theoretical High Energy Physics at the Physical Research Laboratory, Ahmedabad, and the University of Hyderabad.

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

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

    Evaluation of the quality of care of the newborn with complications is an indispensable element for the improvement of strategies directed to reduce newborn mortality rates. The aim of this work was to evaluate the quality of technical and interpersonal care in the management of transient tachypnea of the newborn (TTN) of patients affiliated with the program "Medical Insurance Siglo XXI". A cross-sectional study was conducted in 61 hospitals affiliated with the Health Ministry with at least two cases of TTN during the first semester of 2011. Variables such as mother's health, pregnancy, birth and birth complication characteristics were analyzed. Also, newborn interventions and health conditions upon discharge were included. To measure the quality of care according to prevention, diagnosis and treatment, quality indicators were defined and validated. We analyzed 256 case files with a diagnosis of TTN; 8.9% of the mothers presented risk factors (asthma, diabetes) and 53.5% had complications during pregnancy. There were 60% of cases with TTN born by cesarean delivery; one third of these children had low birth weight and 14% were transferred to another hospital. As for the quality indicators in the area of prevention, more than 90% of risk factors (smoking, asthma, cesarean delivery) were identified. Diagnostic indicators showed that 86-98% of respiratory distress symptoms were sought. Indicators of treatment achieved satisfactory figures for monitoring and support measures. Prevention, diagnosis and treatment indicators made it possible to consider that most TTN cases received appropriate treatment. It is advisable to develop effective strategies to prevent TTN, such as increasing efforts to reduce the increasing rates of cesarean deliveries.

Tales parámetros unidos a los recursos que ofertan las tecnologías emergentes otorgan una enorme creatividad y aportan aspectos humanistas a la comunicación en red, claves de la fuerza persuasiva que caracteriza a estas plataformas online. De esta forma podemos hablar del usuario de redes como el nuevo «rétor» del siglo XXI. Nuestra investigación sobre Facebook aborda la presencia de la ciencia retórica en la comunicación generada en las redes sociales online: el usuario de estas plataformas utiliza las estrategias comunicativas descritas por la disciplina retórica desde sus comienzos en la antigüedad grecolatina.

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

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

    Full Text Available Este artigo discute a dinâmica econômica e a evolução da rede urbana do Ceará nesta primeira década do século XXI. Além das heranças seculares, toma como elemento decisivo na estruturação do espaço cearense as diversas políticas implementadas pelos governos estaduais que articularam a economia cearense aos movimentos das economias brasileira e internacional, influenciando sua organização espacial. Mostra que foi no período colonial que a capital cearense tornou-se principal centro urbano do estado graças à centralização dos excedentes das atividades sertanejas sustentadas no binômio pecuária-algodão. Posteriormente, apresenta as transformações verificadas na fase de integração do mercado nacional, quando se concentraram os principais investimentos na cidade de Fortaleza. Dada essa grande concentração, observam-se esforços de descentralização da atividade produtiva, a partir de uma ação deliberada do governo do estado, através dos instrumentos da guerra fiscal que atraíram para o interior importantes investimentos, sem, contudo, reduzir as disparidades intraestaduais ainda fortemente marcadas pelo predomínio metropolitano. Não obstante, surgem focos dinâmicos na economia cearense, contribuindo para uma maior diferenciação do interior do estado.

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

    Some recent changes in the social mindset are particularly relevant to the geosciences. Among them, the awareness that humanity is an integral, internal part of the Earth System ; the finding that, within this systemic environment, any action affects the whole, and specifically some components ; irrefutable characterization of Man as a geological agent ; and the inevitable acceptance of vulnerability and / or finiteness of certain natural resources. Thus, concepts were developed that has been gaining importance and are now part of a new mentality of the geoscientific community; among them: - Geodiversity: variety of landscapes, rocks, minerals, fossils, soils, etc.. many of these items are the basis of life on Earth. - Geoconservation: enjoyment, conscious use of resources and protection of geodiversity. - Geotourism: tourism that respects the principles of self - sustainability, where the geological information, transmitted properly, play a major role. - Geological Heritage: special portion of the Geodiversity, materialized in geossítios ( outcrops with special features), which deserves protection for future generations. - Geopark: defined area, which is subject to a development plan based on the visit to geossítios and other attractions. Continue her normal activities occurring in the economy. These concepts constitute a holistic view of concern about the conscious use of geological resources. They can also, without abandoning the traditional areas of geology, form themselves into new work front to geologists, which in characteristically multidisciplinary and love of nature training has great potential in it

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

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

    Full Text Available La radio universitaria de tipo “radios libres, radios asociativas” en Francia se remonta a la década de los 60. La experiencia pionera dentro de este marco en territorio francés puede considerarse la aparición, en 1969, de Radio Campus Lille. En el caso español, fue la Universidad de la Laguna, en 1987, la primera institución universitaria que promovió las primeras emisiones universitarias realizadas por los estudiantes del Colegio Mayor San Fernando, aunque los primeros referentes pueden situarse en las emisiones de la UNED a través de Radio 3, a partir de 1979. En la actualidad, las radios universitarias francesas están agrupadas en la Red Radio Campus France. Por su parte, las radios universitarias españolas se agrupan en la Asociación de Radios Universitarias (ARU, creada en 2011. Aunque el número de estaciones radiofónicas universitarias es más o menos similar en ambos países, la realidad y desarrollo es bastante diferente. En este artículo se analiza y se hace una revisión crítica de la situación actual de la radio universitaria en Francia y España.

    Values of partial molar volumes at infinite dilution of 9 inorganic and 4 organic 1:1 electrolytes have been determined in (water + ethylammonium nitrate) (EAN) binary at 298.15 K throughout the composition scale. Our theoretical analysis shows that the values of partial molar volumes at infinite dilution of a solute in a binary are linked to those of the partial molar volumes of the components of mixed solvent. This applies to mixtures of molecular solvents as well as (water + ionic liquid) media. The use of the 'pseudo-lattice theory' of Bahe recently supplemented Varela can be used for calculations and to obtain information about the interactions between 1:1 electrolytes as solutes at infinite dilution and their concentrated saline environment. We show that the 'pseudo-lattice theory' allows accurate description of the behaviours of symmetrical tetraalkylammoniums bromide between the infinitely dilute state and concentrations higher than 2 mol .

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

    The aim of this research was evaluate changes in frequency and intensity of extreme events of precipitation in Brazilian Amazon and Northeast Region, doubling CO2 concentration in agreement of IPCC A2 emissions scenarios (Nakicenovic et al., 2001). For this evaluation was used ETA model (Chou et al., 2011), forced with CCSM3 Global model data (Meehl, 2006) to run 4 experiments, only for January, February and March: 1980-1990, 2000-2010, 2040-2050 and 2090-2100. Using the first decade as reference (1980-1990), was evaluated changes occurred in following decades, with a methodology to classify extremes events adapted from Frich (2002) and Gao (2006). Higher was the class, more intense is the event. An increase of 25% was observed in total precipitation in Brazilian Amazon for the end of XXI century and 12% for extreme events type 1, 9% for events type 2 and 10% for type 3. By the other hand, a 17% decrease of precipitation in Brazilian Northeast was observed, and a pronounced decay of 24% and 15% in extreme events contribution type 1 and 2 to total amount of precipitation, respectively. The difference between total normal type events was positive in this three decades compared with reference decade 1980-1990, varying positively from 4 to 6 thousand events included in normality by decade, these events was decreased in your majority of Class 1 events, which presented a decay of at least 3.500 events by each decade. This suggests an intensification of extreme events, considering that the amount of precipitation by class increased, and the number of events by class decreased. To Northeast region, an increasing in 9% of contribution to events type 3 class was observed, as well as in the frequency of this type of events (about of 700 more events). Major decreasing in number of classes extreme events occur in 2000-2010, to classes 1 and 3, with 7,2 and 5,6%, and by the end of century in class 3, with 4,5%. For the three analyzed decades a total decrease of 8.400 events was

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

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

    Full Text Available En la última década han florecido nociones sobre sumak kawsay y suma qamaña ‘buen vivir’ en Ecuador y Bolivia, respectivamente, al calor de los procesos participativos e innovadoras de las nuevas constituciones políticas. Estas se unen con teorizaciones hechas en otras partes de América Latina, como son el lekil kuxlejal en Chiapas, y el incipiente tb’anil qanq’ib’il entre los maya-mames de Guatemala. Simultáneamente, se señala el auge de la industria extractivista, con alarmantes niveles de depredación. El artículo identifica algunos cuestionamientos del desarrollo occidental y explora las diversas nociones del buen vivir, para luego resaltar la manera en que una mina de oro a cielo abierto, en Guatemala, está destruyendo el ambiente, el tejido social, familiar y comunitario, y muchos elementos locales del buen vivir en San Miguel Ixtahuacán. Recoge las percepciones de mujeres maya-mames que resisten la mina.

These notions have joined processes of theorizing from other Latin America regions, like lekil kuxlejal in Chiapas, and incipient tb’anil qanq’ib’il among the Maya-Mam people from Guatemala. Simultaneously alarming levels of pillage have accompanied the boom of the extraction industry. This article identifies some critiques of Western development and explores different notions of living well/buen vivir to then highlight how open pit mining for gold in Guatemala is destroying the environment, the social fabric, families and communities, as well as many local elements regarding buen vivir in San Miguel Ixtahuacan. It collects perceptions from Maya-Mam women who are resisting the mine.

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

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

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

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

    EVOLUCIÓN DEL SISTEMA OCULAR.

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

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

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

    Full Text Available Argentina, históricamente, ha presentado profundas desigualdades socioeconómicas regionales. Las provincias del Noroeste mostraron notorias diferencias respecto a las pampeanas en la producción de riqueza. Así, a fines del siglo xx, mientras en las provincias pampeanas la pobreza alcanzaba al 32,9% de su población, en el norte estas privaciones se duplicaban. Este artículo tiene por objeto analizar comparativamente las características de estas privaciones —considerando escalas provinciales y departamentales—, vinculándolas a su vez con las transformaciones económicas y productivas y con los problemas de empleo a lo largo del siglo xx e inicios del xxi. Los resultados advierten un notorio proceso de fragmentación socioterritorial como corolario de la persistencia de la desigualdad. Se destaca el recrudecimiento de dicha fragmentación en determinadas provincias y departamentos argentinos.

Los pensadores posmodernos son escépticos respecto de las nociones tradicionales de identidad; los límites que definen al sujeto no sólo construyen sino que también excluyen. Debemos oponernos a las interpretaciones dominantes de normalidad y aceptar otras posibles alternativas a los modelos tradicionales. Necesitamos ir más allá del binario sistema sexo/género y de la orientación sexual y mantener una mentalidad abierta, persiguiendo una filosofía de la libertad.

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

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

    1996-08-01

    This sitewide EIS evaluates the potential environmental impacts of four possible land-use alternatives being considered for the Nevada Test Site (NTS), the Tonopah Test Range, and the formerly operated DOE sites in the state of Nevada: the Project Shoal Area, the Central Nevada Test Area, and portions of the Nellis Air Force Range Complex. Three additional sites in Nevada-Eldorado Valley, Dry Lake Valley, and Coyote Spring Valley-are evaluated for collocation of solar energy production facilities. The four alternatives include Continue Current Operations (No Action, continue to operate at the level maintained for the past 3 to 5 years); Discontinue Operations 1 (discontinue operations and interagency programs); Expanded Use (increased use of NTS and its resources to support defense and nondefense programs); and Alternate Use of Withdrawn Lands (discontinue all defense-related activities at NTS; continue waste management operations in support of NTS environmental restoration efforts; expand nondefense research). Environmental impacts were assessed for each alternative by analyzing, to the extent possible, the discrete and cumulative environmental impacts associated with Defense Waste Management, Environmental Restoration, Nondefense Research and Development, and Work for Others Programs. A framework for a Resource Management Plan is included as Volume 2 of this EIS and represents the development of an ecosystem based planning process closely integrated with the National Environmental Policy Act process. This EIS, among other things, analyzed the impacts of transportation of low level waste, and site characterization activities related to the Yucca Mountain Project but did not analyze the suitability of the site as a repository. This EIS does not analyze the suitability of the Yucca Mountain site as a repository as this is an action beyond the scope of the EIS.

    An article in NASA Tech Briefs describing a vacuum bagging process for forming composite parts helped a small Oklahoma Company to improve its manufacturing process. President of Performance Extremes, Larry Ortega, and his partners make motorcycle parts from carbon/epoxy to reduce weight. Using vacuum bags, parts have a better surface and fewer voids inside. When heat used in the vacuum bag process caused deformation upon cooling, a solution found in another tech brief solved the problem. A metal plate inside the vacuum bag made for more even heat transfer. A third article described a simple procedure for repairing loose connector pins, which the company has also utilized.

    1996-01-01

    The present volume continues the story of the history of the European Organization for Nuclear Research (CERN) in Geneva, Switzerland, concentrating on the years between the mid 1960s and the late 1970s. Whereas the first two volumes were the product of a team of historians, this book is rather a collection of studies by authors with very different professional backgrounds and institutional locations. It also differs from the predecessor volumes in the fact that it consists of distinct case studies dealing with a number of issues deemed important. The first part of this volume, containing contributions by historians of science, perceives the laboratory as being at the node of a complex of interconnected relationships between scientists and science managers on the staff, the users in the member states, and the governments which were called upon to finance the laboratory. In part 2 the physical results, obtained at CERN, are surveyed, while in part 3 two chapters are presented, one on engineering and technology, and the other on the research and development of electronic position detectors

    1985-01-01

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

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

    The Hawaii Demand-Side Management Resource Assessment was the fourth of seven projects in the Hawaii Energy Strategy (HES) program. HES was designed by the Department of Business, Economic Development, and Tourism (DBEDT) to produce an integrated energy strategy for the State of Hawaii. The purpose of Project 4 was to develop a comprehensive assessment of Hawaii`s demand-side management (DSM) resources. To meet this objective, the project was divided into two phases. The first phase included development of a DSM technology database and the identification of Hawaii commercial building characteristics through on-site audits. These Phase 1 products were then used in Phase 2 to identify expected energy impacts from DSM measures in typical residential and commercial buildings in Hawaii. The building energy simulation model DOE-2.1E was utilized to identify the DSM energy impacts. More detailed information on the typical buildings and the DOE-2.1E modeling effort is available in Reference Volume 1, ``Building Prototype Analysis``. In addition to the DOE-2.1E analysis, estimates of residential and commercial sector gas and electric DSM potential for the four counties of Honolulu, Hawaii, Maui, and Kauai through 2014 were forecasted by the new DBEDT DSM Assessment Model. Results from DBEDTs energy forecasting model, ENERGY 2020, were linked with results from DOE-2.1E building energy simulation runs and estimates of DSM measure impacts, costs, lifetime, and anticipated market penetration rates in the DBEDT DSM Model. Through its algorithms, estimates of DSM potential for each forecast year were developed. Using the load shape information from the DOE-2.1E simulation runs, estimates of electric peak demand impacts were developed. Numerous tables and figures illustrating the technical potential for demand-side management are included.

    1994-09-01

    The Los Alamos National Laboratory (LANL) was established in 1943 with its sole mission to develop a fission bomb. Since that time, the mission of the Laboratory has expanded to include not only the primary one of nuclear weapon stockpile stewardship, but also one that supports energy, biomedical, environmental, and physical research. As part of the Laboratory's primary and diverse missions, many forms of plutonium materials are used and stored. Over the years of production and use of plutonium at Department of Energy (DOE) sites, some events have occurred that were unexpected and that have resulted in environmental, safety, and/or health concerns. Some of these events have led to improvements that will preclude these concerns from arising again. However, the end of the cold war and the expansion of the Laboratory mission have introduced the possibility of new vulnerabilities

    President Clinton directed an Interagency Working Group to initiate a comprehensive review of long-term options for the disposition of surplus plutonium. As part of this initiative, Secretary of Energy Hazel O'Leary directed the Department of Energy to develop options and plans for the interim safe storage of these materials. One step in this direction is a plutonium vulnerability assessment of DOE facilities by a open-quotes Plutonium Vulnerability Working Group.close quotes In this effort, the working group developed a Project Plan and an Assessment Plan which basically laid out the approach and methodology for the assessments. The plans were issued on April 25, 1994. The Project Plan specifies a WGAT for each site with significant holdings of plutonium. Also, the plan requires that each site form a Site Assessment Team (SAT) to provide the self assessment for the project. Additionally, the working group was tasked with managing the assessments at each site, and providing the results in a final report for the Secretary by September 30, 1994

    Klinefelter's syndrome (KS) is associated with specific neurobehavioral features and personality traits. The aim of our study was to investigate fluid intelligence, personality traits and personality disorders (PD) and possible correlations with testosterone in a cohort of adult KS patients. We analyzed 58 adult KS patients with the classic 47, XXY karyotype. The Structured Clinical Interview for axis II disorders was used to assess DSM IV personality disorders. Personality traits were assessed using MMPI-2. Fluid intelligence was tested by using Raven's Standard Progressive Matrices (SPM) Test. Testosterone blood concentration was measured by CMIA. PD prevalence was 31%. Four altered MMPI scales (Social Responsibility, Dominance, Ego Strength and Repression) were found in more than 40% of patients. Overcontrolled hostility and MacAndrew Alcoholism Scale-Revised scales were altered in the PD- group only. Biz-Odd Thinking and Post-Traumatic Stress Disorder scale were associated with the presence of personality disorder. The raw SPM score was 44 ± 10.8 without any significant correlation with testosterone. No significant difference in mean age, SPM raw score and MMPI score was observed between eugonadal, hypogonadal and treated patients. Most KS patients had average fluid intelligence. PD prevalence was higher than in the general population. Testosterone was not correlated with fluid intelligence, personality traits or PD, but a reduction in marital distress was observed in treated patients. This could suggest that testosterone therapy can improve physical symptoms and this effect could also improve relationship abilities and wellness awareness.

    Full Text Available From the last decades of the twentieth century, the rural sector of the Argentine Northwest was the scene of deep territorial and productive transformations linked to the expansion of extractive activities. The effects of these activities include privatization, concentration and land grabs, generating an increase of social and territorial inequality. The aim of this paper is therefore to analyze the socio-territorial inequality in rural areas of Northwest Argentina in the first decade of the XXI century. Four dimensions were analyzed: poverty, education, habitat quality, and agrarian structure. For the analysis of the first three dimensions, data from national population census 2001 and 2010 were used. For the analysis of the territorial and productive transformations were used data from national agricultural censuses 1988, 2002 and 2008. The results allow us to observe that while the habitat quality and education improved during the first decade of the century, there are high poverty and vulnerability in a context of a progressively unequal agrarian structure.

    Residential ventilation systems with a heat recovery contribute to the improvement of the air quality and to the reduction of heat losses caused by ventilation. An additional opening of the windows in residential buildings results in a clearly increasing consumption of thermal heat because the thermal heat of the out coming air cannot be utilized furthermore. Continuous information on the energetic effects of the opening of windows is helpful. Under this aspect, the authors of the contribution under consideration report on the development of energy efficient comfort ventilation systems with an air quality controlled volume flow rate and continuous detection of the status of the windows aperture. The contribution under consideration is the third part of a project concerning to this theme. This part encompasses a field test with four single-family houses in which the air quality control as well as the detection of the status of the windows aperture is tested and optimized for a long period. This contribution also contains the results of the second part of the project. The second project investigate the technical implementation of a air quality regulation at prototypes and test facilities.

    The report presents the preparatory work on the research project of the above title. The first chapter presents a status report on air quality monitoring inside rooms and evaluates the projects so far in which the LuQaS air quality sensor was used. The second chapter is a documentation of preliminary measurements using the LuQaS sensor in two passive residential buildings and several individual measurements for sensor calibration. It was found that in apartments with mechanical ventilation, the sensor reflects the user activities; further, the measured values indicate signal changes also in the off-air of the building, so that control via central sensors in the ventilation and off-air systems appears feasible. The third chapter discusses control strategies for air quality control. Apart from a discussion of control unit types, operating regimes, methods to determine rated values, and additional control functions, the effects of threshold value control with different threshold limit values and volume flow changes on the air quality of a model building was simulated. The results prove the expectation that the air quality inside a building will be influenced positively by air quality control. Theoretical investigations of the DrD method will be presented in another part-report of the project.

  20. Quantifying Uncertainty in Soil Volume Estimates

    Roos, A.D.; Hays, D.C.; Johnson, R.L.; Durham, L.A.; Winters, M.

    2009-01-01

    Proper planning and design for remediating contaminated environmental media require an adequate understanding of the types of contaminants and the lateral and vertical extent of contamination. In the case of contaminated soils, this generally takes the form of volume estimates that are prepared as part of a Feasibility Study for Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) sites and/or as part of the remedial design. These estimates are typically single values representing what is believed to be the most likely volume of contaminated soil present at the site. These single-value estimates, however, do not convey the level of confidence associated with the estimates. Unfortunately, the experience has been that pre-remediation soil volume estimates often significantly underestimate the actual volume of contaminated soils that are encountered during the course of remediation. This underestimation has significant implications, both technically (e.g., inappropriate remedial designs) and programmatically (e.g., establishing technically defensible budget and schedule baselines). Argonne National Laboratory (Argonne) has developed a joint Bayesian/geostatistical methodology for estimating contaminated soil volumes based on sampling results, that also provides upper and lower probabilistic bounds on those volumes. This paper evaluates the performance of this method in a retrospective study that compares volume estimates derived using this technique with actual excavated soil volumes for select Formerly Utilized Sites Remedial Action Program (FUSRAP) Maywood properties that have completed remedial action by the U.S. Army Corps of Engineers (USACE) New York District.

  1. Fiber-reinforced concretes with a high fiber volume fraction — a look in future. Can a design determine the fiber amount in concrete in real time in every part of a structure in production?

    Tepfers, R.

    2010-09-01

    In near future, when the control of the load-bearing capacity of fiber-only-reinforced concrete members will be safely guaranteed, the deletion of the ordinary continuous steel reinforcing bars might be possible. For the time being, it is difficult to change the fiber amount during the casting with today's techniques. Therefore, the fiber concentration has to be determined by the maximum tensile stress in concrete structural members, resulting in an unnecessary fiber addition in compressed zones. However, if the right amount of fibers could be regulated and added to concrete in real time at the pump outlet, a future vision could be to design and produce a structure by using FEM-controlled equipment. The signals from calculation results could be transmitted to a concrete casting system for addition of a necessary amount of fibers to take care of the actual tensile stresses in the right position in the structure. The casting location could be determined by using a GPS for positioning the pump outlet for targeting the casting location horizontally and a laser vertically. The addition of fibers to concrete at the outlet of a concrete pump and proportioning them there according to the actual needs of the stress situation in a structure, given by a FEM analysis in real time, is a future challenge. The FEM analysis has to be based on material properties of fiber-only-reinforced concrete. This means that the resistance and stiffness of different-strength concrete members with a varying fiber content has to be determined in tests and conveyed to the FEM analysis. The FEM analysis has to be completed before the casting and controlled. Then it can be used as the base for adding a correct amount of fibers to concrete in every part of the structure. Thus, a system for introducing a correct amount of fibers into concrete has to be developed. The fibers have to be added at the outlet of concrete pump. Maybe a system to shotcrete concrete with electronically controlled fiber

    Since May 1996, under its draft Civilian Radioactive Waste Management Program Plan (DOE 1996), DOE has been carrying out a 5-year program of work to support the decision in 2001 by the Secretary of Energy on whether or not to recommend the site to the President. Part of this program was to address major unresolved technical issues and to complete an assessment of the viability of the Yucca Mountain site by 1998. Affirming the DOE plans, Congress directed DOE in the 1997 Energy and Water Development Appropriations Act to provide a viability assessment of the Yucca Mountain site to Congress and the President. This Viability Assessment (VA) document is the DOE report to Congress and the President. They are expected to use the VA to make an informed decision about program direction and funding. Drawing on 15 years of scientific investigation and design work at Yucca Mountain, the VA summarizes a large technical basis of field investigations, laboratory tests, models, analyses, and engineering, described in cited references. The VA identifies the major uncertainties relevant to the technical defensibility of DOE analyses and designs, the DOE approach to managing these uncertainties, and the status of work toward the site recommendation and LA. The VA also identifies DOE plans for the remaining work, and the estimated costs of completing an LA and constructing and operating a repository. The attention to uncertainties is important because DOE must evaluate how the repository will perform during the next 10,000 years or longer. Uncertainties exist because of variability in the natural (geologic and hydrologic) systems at Yucca Mountain and because of imperfect scientific understanding of the natural processes that might affect the repository system. This is Volume 1 and it covers, Introduction and Site Characteristics, includes a high-level summary of the results of the VA and some additional background information.

Este estudio se desarrolló en la Unidad de Investigación de Análisis de Políticas Públicas y Desarrollo Socio-educativo de la Universidad de Carabobo. Tomando como referencias teóricas a E. Morin y J. Habermas, se desarrollan tres categorías presentes en la realidad de Venezuela: el Socialismo del Siglo XXI, el Estado Docente y la Autonomía Universitaria. El tratamiento metodológico parte del planteamiento de la premisa: el Nuevo Modelo de Educación Universitaria que está por construirse, se debe a la crisis del modelo cognitivo instrumental instituido en la Constitución de la República de Venezuela (1961, sus Leyes y Reglamentos. Al triangular las tres categorías se plantea, como valor agregado, concebir la educación a través de un proceso transdisciplinario, sustentado en una primera instancia por el ordenamiento jurídico que le dé concreción y sincronización en el tiempo y el movimiento. En el caso de la educación venezolana, se concluye que no se han producidos cambios significativos que nos indiquen que estamos en presencia de un nuevo modelo de educación. La educación universitaria sigue atada al modelo cognitivo instrumental, impidiendo cualquier cambio que desde su seno se pretenda impulsar, de manera que la nueva Ley de Educación Universitaria y el nuevo modelo de educación siguen diferido.Abstract: This essay is based on an analysis of the higher education in the context socio-political of the Venezuelan reality, in the reference period is 2007-2013, focused the promulgation of the organic law of education (2009.

  4. Lung volumes: measurement, clinical use, and coding.

    Flesch, Judd D; Dine, C Jessica

    2012-08-01

    Measurement of lung volumes is an integral part of complete pulmonary function testing. Some lung volumes can be measured during spirometry; however, measurement of the residual volume (RV), functional residual capacity (FRC), and total lung capacity (TLC) requires special techniques. FRC is typically measured by one of three methods. Body plethysmography uses Boyle's Law to determine lung volumes, whereas inert gas dilution and nitrogen washout use dilution properties of gases. After determination of FRC, expiratory reserve volume and inspiratory vital capacity are measured, which allows the calculation of the RV and TLC. Lung volumes are commonly used for the diagnosis of restriction. In obstructive lung disease, they are used to assess for hyperinflation. Changes in lung volumes can also be seen in a number of other clinical conditions. Reimbursement for measurement of lung volumes requires knowledge of current procedural terminology (CPT) codes, relevant indications, and an appropriate level of physician supervision. Because of recent efforts to eliminate payment inefficiencies, the 10 previous CPT codes for lung volumes, airway resistance, and diffusing capacity have been bundled into four new CPT codes.

  5. Specification of volume and dose in radiotherapy

    Levernes, S.

    1997-01-01

    As a result of a questionnaire about dose and volume specifications in radiotherapy in the Nordic countries, a group has been set up to propose common recommendations for these countries. The proposal is partly based on ICRU 50, but with major extensions. These extensions fall into three areas: patient geometry, treatment geometry, and dose specifications. For patient geometry and set-up one need alignment markings and anatomical reference points, the latter can be divided into internal and external reference points. These points are necessary to get relationships between coordinate systems related to patient and to treatment unit. For treatment geometry the main volume will be an anatomical target volume which just encompass the clinical target volume with all its variations and movements. This anatomical volume are the most suitable volume for prescription, optimization and reporting dose. A set-up margin should be added to the beam periphery in beams-eye-view to get the minimum size and shape of the beam. For dose specification the most important parameter for homogeneous dose distributions is the arithmetic mean of dose to the anatomical target volume together with its standard deviation. In addition the dose to the ICRU reference point should be reported for intercomparison, together with minimum and maximum doses or dose volume histograms for the anatomical target volume. (author)

    A system for measuring flow rate within a volume includes one or more transmission devices that transmit one or more signals through fluid contained within the volume. The volume may be bounded, at least in part, by an outer structure and by an object at least partially contained within the outer structure. A transmission device located at a first location of the outer structure transmits a first signal to a second location of the outer structure. A second signal is transmitted through the fluid from the second location to a third location of the outer structure. The flow rate of the fluid within the volume may be determined based, at least in part, on the time of flight of both the first signal and the second signal.

    Full Text Available El presente artículo trata sobre la “expansión” del neoliberalismo a las prácticas organizacionales contemporáneas. Entendemos al neoliberalismo como la lógica comportamental basada en la empresa y la competencia que, actualmente, prevalece con la pretensión de colonizar las diferentes esferas de lo social. En las últimas décadas, se han producido una serie de transferencias de herramientas de gestión propias del business a los modos de organización del trabajo estatal y, entre estos desplazamientos, encontramos el de la práctica del marketing. Considerándolo a éste como una tecnología que busca garantizar la competencia, estudiamos su funcionamiento en el marketing coordinado por la gestión pública del turismo. Tomando como caso a la Argentina del siglo XXI, analizamos el objetivo de comunicación comercial que remite al posicionamiento en articulación con otros componentes: el mecanismo de construcción de imagen y el diseño de marca de destinos/productos. Esta investigación tuvo la finalidad de interpretar críticamente los intentos de control sobre los trabajadores del sector público y de los prestadores privados que el Estado capacita. Concluimos que estos elementos operan como pautas generales y “mandatos” indirectos de conducción de los recursos humanos sobre cómo en la actualidad “hay” que trabajar en el marco de la gubernamentalidad neoliberal.

    The NASA Propagation Experimenters (NAPEX) meeting is convened each year to discuss studies supported by the NASA Propagation Program. Representatives from the satellite communications industry, academia and government who have an interest in space-ground radio wave propagation are invited to NAPEX meetings for discussions and exchange of information. The reports delivered at this meeting by program managers and investigators present recent activities and future plans. This forum provides an opportunity for peer discussion of work in progress, timely dissemination of propagation results, and close interaction with the satellite communications industry. NAPEX XXI took place in El Segundo, California on June 11-12, 1997 and consisted of three sessions. Session 1, entitled "ACTS Propagation Study Results & Outcome " covered the results of 20 station-years of Ka-band radio-wave propagation experiments. Session 11, 'Ka-band Propagation Studies and Models,' provided the latest developments in modeling, and analysis of experimental results about radio wave propagation phenomena for design of Ka-band satellite communications systems. Session 111, 'Propagation Research Topics,' covered a diverse range of propagation topics of interest to the space community, including overviews of handbooks and databases on radio wave propagation. The ACTS Propagation Studies miniworkshop was held on June 13, 1997 and consisted of a technical session in the morning and a plenary session in the afternoon. The morning session covered updates on the status of the ACTS Project & Propagation Program, engineering support for ACTS Propagation Terminals, and the Data Center. The plenary session made specific recommendations for the future direction of the program.

Tras una introducción multidisciplinar, abogando por la necesidad de la recuperación de la ética en el conjunto de todas las profesiones, se analiza el concepto de resiliencia, para dotarlo de contenido y significado. Resiliencia se convierte en el elemento nuclear de muchas de las políticas actualmente implementadas en la Comunidad Europea. Este naciente “mantra de desarrollo” de la resiliencia promete la recuperación de las potencialidades frente a una crisis eventual y la renovación reforzada con mejores perspectivas que antes de la misma. Dada la relativa ambigüedad y todavía escasa aplicación del concepto de resiliencia en general para el conjunto de la sociedad, exploramos la triada propuesta (ética-economía-información que nos puede conducir a la resiliencia. Entender estos tres elementos en modo integral puede permitir a la biblioteca y al profesional de la información poder participar en modo adecuado en esta tarea de la resiliencia sea a nivel local como, potencialmente, también en modo global.

    Improved fuel performance is a key issue in the current Laser Inertial-Confinement Fusion-Fission Energy (LIFE) engine design. LIFE is a fusion-fission engine composed of a ∼40-tons fuel blanket surrounding a pulsed fusion neutron source. Fusion neutrons get multiplied and moderated in a Beryllium blanket before penetrating the subcritical fission blanket. The fuel in the blanket is composed of millions of fuel pebbles, and can in principle be burned to over 99% FIMA without refueling or reprocessing. This report contains the following chapters: Chapter A: LIFE Requirements for Materials -- LIFE Fuel; Chapter B: Summary of Existing Knowledge; Chapter C: Identification of Gaps in Knowledge and Vulnerabilities; and Chapter D: Strategy and Future Work.

    Full Text Available The aim of this article is to analyze the dynamics of social conflict in Chile during the period 2000-2011. We elaborate catalogues of contention actions from Clacso’s “Cronologías del Conflicto Social”, that are the basis to identify actors, actions, and adversaries. The specific objective is double: on one hand, to take to the limit the theoretical foundations in which a large part of academic interpretations of social conflict are based, evaluating their utility and possible criticisms; on the other, to evaluate whether those who mobilize respond to a heteronomous dynamics of conflict or rather are subjects with an autonomous capacity of action. With this analysis we expect to have enough elements to elaborate an outline of the repertoire of contention in Chile during this Century.

    Full Text Available This article presents a vision of how the Occidental World has been awaken from the “modernity” dream, in which there is a construction of values like secularity, laicism, economical competition, and military acting, among others. And how religion, seen by some intellectuals as a remnant of the traditional world, has contributed in a big way to this awakening. In this way, in the article is possible to state that religion is one of the aspects that alter the most the economical and institutional principles of the Occidental World. So, it is necessary to wonder if the principles of the Occidental World will prevail and what other political and economical directions will be generated as a result of the deep influence that religion has over the individual and the communities.En este artículo se presenta una visión de cómo el mundo Occidental ha sido despertado del llamado sueño de la “modernidad”, en el que se parte de la base de la construcción de valores como la secularidad, el laicismo, la competencia económica, el desempeño militar, entre otros. Y cómo a este despertar ha contribuido, en gran parte, la religión, vista por algunos intelectuales como los vestigios del mundo tradicional. En este sentido, en el artículo es posible afirmar que la religión es uno de los panoramas que más alteran los principios económicos e institucionales del mundo Occidental. Queda, entonces, preguntarse si el mundo occidental podrá hacer prevalecer sus principios y qué otros giros políticos y económicos podrán generarse a raíz de la influencia cada vez más profunda que la religión tiene sobre el individuo y las colectividades.

    Full Text Available BACKGROUND: Eponym from the Greek [epi, "upon"] + [onuma, name], is a person, whether real or fictitious, after whom an item is named or thought to be named. Eponymous terms are used every day in Medicine, in our clinical years, and they have been part of the tradition of Medicine, culture, and history. Despite all the inconvenience, all those who are no against eponym has only one statement: "medical eponyms will continue to be used because there is a sense of history to their use. They are use in contemporary life, eponyms are here to stay". METHODS: The following study aims at to show the presence of current anatomical eponyms on the best well-known Textbooks and Atlas of Human Anatomy, ranging from the oldest to the newest one, comprising a period from 1960 until 2011, regarding the cardiovascular system, particularly the heart. The three International Anatomical Terminologies have been critical as the basis of our study. Exclusion criteria were syndromes, diseases, signs, anomalies, surgical procedures, indexes, tests, grading, and the methods, which are used as eponyms in Cardiology, once they are not considered Anatomical Terms. It has been our intent to show that different eponyms characterize the same anatomical structure. RESULTS: A list with the 25 most common eponyms listed by the three International Anatomical Terminologies is listed in Table1. CONCLUSION: Should eponyms be abandoned? Of course not, once they remain a useful reflection of medical history. We could prove to our journey from 1960 to 2011, that the best well-known Atlas and Textbooks available do not use so many anatomical eponyms in Cardiology. They are only 25 (without including arteries, veins, and nerves of the cardiovascular system and all the authors use no more than 9 or 12 of them. We just want to alert the Health and Allied Health Sciences Professional and students that we 'strongly recommend' not to use an eponym when it is made at the expense of an

El creciente éxito de estrellas como Denzel Washington, Idris Elba o Omar Sy, junto a la irrupción en los Oscars de 2014 del director Steve McQueen, está facilitando el desarrollo de un nicho de público transnacional, formado sobre todo por jóvenes afrodescendientes cada vez más conscientes y deseosos de verse representados por personajes negros en papeles importantes. De Estados Unidos a Europa, estamos asistiendo al surgimiento de una sensibilidad más proactiva, flexible y pragmática por parte de directores afrodescendientes, que se mueven con distintas estrategias de política identitaria y de relación con la industria, pero con los mismos objetivos de empoderamiento. La referencia a la agenda nacional e identitaria, cuando está presente de una forma marcada, sí que tiende a construir una relación privilegiada con un público de referencia afrodescendiente, pero apuesta también por influir en el imaginario y el mercado mainstream. Llama la atención el intento de algunos de deshacerse de la hipoteca de un peso de la representación que sigue afectando a directores afrodescendientes, con la complicidad de una crítica cinematográfica que sigue interpretando la experiencia de los directores afrodiaspóricos desde una perspectiva discontinuista, excepcionalista, como expresión de una «comunidad imaginada», además, cada vez más difícil de circunscribir. Lo que me propongo es recorrer, de manera no sistemática, el trayecto que han realizado las personalidades afrodescendientes más significativas que emergieron o se confirmaron en el panorama cinematográfico durante el período examinado, con atención especial a Francia, Gran Bretaña y Estados Unidos.Palabras clave: Cine, diáspora, África, transnacionalismo, post

  19. Do new anesthesia ventilators deliver small tidal volumes accurately during volume-controlled ventilation?

    Science.gov (United States)

    Bachiller, Patricia R; McDonough, Joseph M; Feldman, Jeffrey M

    2008-05-01

    During mechanical ventilation of infants and neonates, small changes in tidal volume may lead to hypo- or hyperventilation, barotrauma, or volutrauma. Partly because breathing circuit compliance and fresh gas flow affect tidal volume delivery by traditional anesthesia ventilators in volume-controlled ventilation (VCV) mode, pressure-controlled ventilation (PCV) using a circle breathing system has become a common approach to minimizing the risk of mechanical ventilation for small patients, although delivered tidal volume is not assured during PCV. A new generation of anesthesia machine ventilators addresses the problems of VCV by adjusting for fresh gas flow and for the compliance of the breathing circuit. In this study, we evaluated the accuracy of new anesthesia ventilators to deliver small tidal volumes. Four anesthesia ventilator systems were evaluated to determine the accuracy of volume delivery to the airway during VCV at tidal volume settings of 100, 200, and 500 mL under different conditions of breathing circuit compliance (fully extended and fully contracted circuits) and lung compliance. A mechanical test lung (adult and infant) was used to simulate lung compliances ranging from 0.0025 to 0.03 L/cm H(2)O. Volumes and pressures were measured using a calibrated screen pneumotachograph and custom software. We tested the Smartvent 7900, Avance, and Aisys anesthesia ventilator systems (GE Healthcare, Madison, WI) and the Apollo anesthesia ventilator (Draeger Medical, Telford, PA). The Smartvent 7900 and Avance ventilators use inspiratory flow sensors to control the volume delivered, whereas the Aisys and Apollo ventilators compensate for the compliance of the circuit. We found that the anesthesia ventilators that use compliance compensation (Aisys and Apollo) accurately delivered both large and small tidal volumes to the airway of the test lung under conditions of normal and low lung compliance during VCV (ranging from 95.5% to 106.2% of the set tidal volume

    Full Text Available

    First I explore, very briefly, the avatars of the relationship between place and design in the past century, in relation to the quality of the project, reflecting on the different attitudes in this regard.
    Within its second part, the article introduces recent theories on the functioning of dialogic imagination, for which the site ceases to be something suspicious or secondary in order to become something irreplaceable and necessary for the designer. In this way, the work of the architect throughout the project is related to education, construction, and his social life; a very ambitious goal, but necessary if we want to maintain the legitimacy of the Architecture profession.
    The functioning of this dialogic imagination is explained by means of plainly represented examples that illustrate the real possibilities of these theories. In these examples, the dialogue between design and place enriches the quality of the architecture and planning that end up being built. Simultaneously, the interactions between Architecture, culture and society are made manifest, allowing the architect to assert his/her ability to investigate alongside other professions and disciplines.
    Finally, in the conclusions, the article recognizes that the quality of the physical and social place of the project is responsibility of the architect. Processes of globalization, more and more fast, can not be the excuse for the social networks of power that underlie the construction of increasingly large territories, because they may result less habitables each day.
    The article is accompanied by a bibliography of Lewis Mumford, as well as a brief text written by him.
