    The dynamics of a stiffnite are here inferred. A stiffnite is a sheet-shaped, gravity-driven submarine sediment flow, with a fabric made up of marine ooze. To infer stiffnite dynamics, order of magnitude estimations are used. Field deposits and experiments on materials taken from the literature are also used. Stiffnites can be tens or hundreds of kilometers wide, and a few centimeters/ meters thick. They move on the sea slopes over hundreds of kilometers, reaching submarine velocities as high as 100 m/s. Hard grain friction favors grain fragmentation and formation of triboelectrically electrified particles and triboplasma (i.e., ions + electrons. Marine lipids favor isolation of electrical charges. At first, two basic assumptions are introduced, and checked a posteriori: (a in a flowing stiffnite, magnetic dipole moments develop, with the magnetization proportional to the shear rate. I have named those dipoles as Ambigua. (b Ambigua are ‘vertically frozen’ along stiffnite streamlines. From (a and (b, it follows that: (i Ambigua create a magnetic field (at peak, >1 T. (ii Lorentz forces sort stiffnite particles into two superimposed sheets. The lower sheet, L+, has a sandy granulometry and a net positive electrical charge density. The upper sheet, L–, has a silty muddy granulometry and a net negative electrical charge density; the grains of sheet L– become finer upwards. (iii Faraday forces push ferromagnetic grains towards the base of a stiffnite, so that a peak of magnetic susceptibility characterizes a stiffnite deposit. (iv Stiffnites harden considerably during their motion, due to magnetic confinement. Stiffnite deposits and inferred stiffnite characteristics are compatible with a stable flow behavior against bending, pinch, or other macro instabilities. In the present report, a consistent hypothesis about the nature of Ambigua is provided.

    This monograph deals with assessment of radiological health effects of the Chernobyl accident for emergency workers (part 1) and the population of the contaminated areas in Russia (part 2). The Chernobyl emergency workers and people living in the contaminated areas of Russia received much lower doses than the population of Hiroshima and Nagasaki and it was unclear whether risks of radiation-induced cancers derived with the Japanese data could be extrapolated to the low dose range However, it was predicted as early as in 1990 that the thyroid cancer incidence might be increasing due to incorporated 131 irradiation. What conclusions can be drawn from regarding cancer incidence among emergency workers and residents of the contaminated areas in Russia and the role of the radiation factor on the basis of the registry data? Leukemia incidence. Leukemia incidence is known to be one of principal indications of radiation effects. The radiation risk for leukemias is 3-4 times higher that for solid cancers and its latent period is estimated to be 2-3 years after exposure. Results of the radiation epidemiological studies discussed in this book show that in the worst contaminated Bryansk region the leukemia incidence rate is not higher than in the country in general. Even though some evidence exists for the dose response relationship, the radiation risks appear to be not statistically significant. Since risks of leukemia are known to be higher for those who were children at exposure, long-term epidemiological studies need to be continued. The study of leukemias among emergency workers strongly suggest the existence of dose response relationship. In those who received external doses more than 0.15 Gy the leukemia incidence rate is two time higher and these emergency workers should be referred to as a group of increased radiation risk. Solid cancers. The obtained results provide no evidence to a radiation-induced increase in solid cancers among residents of the contaminated areas

    2011-01-01

    Although the concept of picture archiving and communications systems (PACS) was developed in Europe during the latter part of the 1970s, no working system was completed at that time. The first PACS implementations took place in the United States in the early 1980s, e.g. at Pennsylvania University, UCLA, and Kansas City University. Some more or less successful PACS developments also took place in Europe in the 1980s, particularly in the Netherlands, Belgium, Austria, the United Kingdom, France, Italy, Scandinavia, and Germany. Most systems could be characterized by their focus on a single department, such as radiology or nuclear medicine. European hospital-wide PACS with high visibility evolved in the early 1990s in London (Hammersmith Hospital) and Vienna (SMZO). These were followed during the latter part of the 1990s by approximately 10-20 PACS installations in each of the major industrialized countries of Europe. Wide-area PACS covering several health care institutions in a region are now in the process of being implemented in a number of European countries. Because of limitations of space some countries, for example, Denmark, Finland, Spain, Greece, as well as Eastern European countries, etc. could not be appropriately represented in this paper.

    Full Text Available Psoriasis is a chronic inflammatory skin disease affecting about 1–3% of the general population. Recent years have seen great development in the treatment of this dermatosis, especially regarding moderate to severe psoriasis. More numerous and more widely available systemic therapies raise new challenges for all physicians treating patients with psoriasis. New questions arise about patients’ follow-up and long-term safety of such therapies. To meet the expectations of Polish dermatologists, we have prepared a second part of guidelines on the treatment of psoriasis, particularly concentrated on the therapy of severe forms of this disease. We hope that our suggestions will be valuable for physicians in their daily clinical practice. However, we would like to underline that every guideline is characterized by some vagueness, and the final decision about diagnosis and therapy should always be made individually for every patient based on the patient’s current clinical status and the most up-to-date scientific literature data.

    Full Text Available Three-dimensional (3D textile structures with better delamination resistance and damage impact tolerance to be applied in composites for structural components is one of the main goals of the aeronautical industry. Textile Research Centre in Canet de Mar has been working since 2008 in this field. Our staff has been designing, developing and producing different textile structures using different production methods and machinery to improve three-dimensional textile structures as fiber reinforcement for composites. This paper describes different tests done in our textile labs from unidirectional structures to woven, knitted or braided 3 D textile structures. Advantages and disadvantages of each textile structure are summarized. The second part of this paper deals with our know-how in the manufacturing and assessing of three-dimensional textile structures during this last five years in the field of textile structures for composites but also in the development of structures for other applications. In the field of composites for aeronautic sector we have developed textile structures using the main methods of textile production, that is to say, weaving, warp knitting, weft knitting and braiding. Comparing the advantages and disadvantages it could be said that braided fabrics, with a structure in the three space axes are the most suitable for fittings and frames.

    2012-03-01

    Cognitive science has become the most influential paradigm on mental health in the late 20(th) and the early 21(st) centuries. In few years, the concepts, problem approaches and solutions proper to this science have significantly changed. Introduction and discussion of the fundamental concepts of cognitive science divided in four stages: Start, Classic Cognitivism, Connectionism, and Embodying / Enacting. The 2(nd) Part of the paper discusses the above mentioned fourth stage and explores the clinical setting, especially in terms of cognitive psychotherapy. The embodying/enacting stage highlights the role of the body including a set of determined evolutionary movements which provide a way of thinking and exploring the world. The performance of cognitive tasks is considered as a process that uses environmental resources that enhances mental skills and deploys them beyond the domestic sphere of the brain. On the other hand, body and mind are embedded in the world, thus giving rise to cognition when interacting, a process known as enacting. There is a close connection between perception and action, hence the interest in real-time interactions with the world rather than abstract reasoning. Regarding clinics, specifically the cognitive therapy, there is little conceptual discussion maybe due to good results from practice that may led us to consider that theoretical foundations are firm and not problem-raising.

  9. Development of aero-engines, part II

    Energy Technology Data Exchange (ETDEWEB)

    Dehn, K.

    1943-01-01

    In the second part of his paper, Mr. Dehn enters into the area of problems in engine construction and design. The main question was, how can more power be coaxed from an engine without increasing its stroke displacement and weight. To begin with, a change in combustion-chamber configuration was made. A hemispheric chamber appeared to be the best design. Into this new design was incorporated a system to swirl the fuel-air mixture for better combustion and more power. Also needed was relocation of the spark plug. Since there was better combustion, valves had to be improved. These were hollowed, filled with sodium and finished with chromium or stellite for more hardness. However, the temperature created by these improvements proved to be a serious problem in engine durability. Heat corrosion destroyed pistons and rings, causing the engine not just to seize-up, but to come apart. This resulted in the loss of aircraft. Finally, a system of cooling the pistons from beneath by an oil spray increased both performance and piston life. Dehn summarizes his paper by comparing two cylinder units from Curtis-Wright radial engines, one old, the other new. He claims that these represented advances in engine technology in all areas he discussed. First, the size had not been increased, but the newer one developed more power. This had been accomplished, he reports, by fuel development reducing pre-detonation. The super-charging, and most important, the re-design of the cooling fins on the cylinder head exterior, provided greater thermal capacity for the engine. In this way, power had been increased more than 100 percent. The author concludes his paper by stating that this type of development is possible only through advances in, and use of, materials technology. That would involve intensive co-operation between the scientists and engineers working in fuels development and aviation engineering.

    A. Insulinoma
    En 1927 se informó el primer caso en la Clínica Mayo. Esta misma institución posee una de las series más grandes sobre el tema con 200 casos reportados; sin embargo, su incidencia global es del orden de menos de I caso por 100.000 habitantes. En una serie de 1.067 pacientes realizada en Italia, el tumor se presentó aproximadamente en un 60% en mujeres y un 40% en hombres, siendo el rango de edad entre los 30 y 60 años (21.

    l. Manifestaciones clínicas
    Las manifestaciones son debidas a la hipoglicemia secundaria al hiperinsulinismo circulante.

    Los síntomas neurosiquiátricos incluyen: pérdida de conciencia, confusión, vértigo, alteraciones visuales, astenia, coma profundo y epilepsia; se han reportado casos con daño del sistema nervioso central irreversible y parálisis temporal; además también puede haber somnolencia, amnesia, ataxia, cefalea, parestesias, signo de Babinski, agitación e irritabilidad.

    Estos se explican, en gran parte, debido a que elcerebro depende casi exclusivamente de la oxidación de la glucosa para proveer sus necesidades energéticas. En estos pacientes también son frecuentes síntomas de tipo adrenérgico tales como sudoración, temblor, empalidecimiento y síntomas cardiovasculares como palpitaciones, taquicardia, dolor precordial e hipertensión arterial. También se presentan síntomas gastrointestinales como sensación de hambre, vómito y, ocasionalmente, dolor epigástrico.

    2013-01-01

    In recent years some of the best theoretical work on the political economy of political institutions and processes has begun surfacing outside the political science mainstream in high quality economics journals. This two-part paper surveys these contributions from a recent five-year period. In Part I, the focus is on elections, voting and information aggregation, followed by treatments of parties, candidates, and coalitions. In Part II, papers on economic performance and redistribution, constitutional design, and incentives, institutions, and the quality of political elites are discussed. Part II concludes with a discussion of the methodological bases common to economics and political science, the way economists have used political science research, and some new themes and arbitrage opportunities.

    Treatments for localized adiposities range from topical creams to liposuction. Most treatments lack a substantial proof of efficacy. The unpredictable treatment outcome can be related to the fact that cellulite adipose tissue is physiologically and biochemically different from subcutaneous tissue found elsewhere in the body. Part II of this two-part series on cellulite reviews the various treatment options that are currently available for human adipose tissue including, but not limited to, cellulite. It also focuses on newer techniques that can be potentially useful in the future for the treatment of cellulite. Copyright 2010 American Academy of Dermatology, Inc. Published by Mosby, Inc.

    Full Text Available La ansiedad escénica es uno de los principales problemas a los que los músicos, estudiantes y profesionales, deben enfrentarse. El perfeccionismo es un constructo asociado a problemas de fobia social como pueda ser la ansiedad escénica. La asociación entre perfeccionismo y ansiedad escénica no ha recibido especial atención dentro del ámbito investigador y formativo español. Objetivos: Estudiar la presencia de niveles de ansiedad escénica en una muestra de estudiantes del Conservatorio Superior de Música de Alicante y cómo se relaciona ésta con el perfeccionismo y las calificaciones obtenidas. Método: El estudio de los datos es cuantitativo mediante un diseño selectivo con un muestreo por disponibilidad. Las respuestas corresponden a dos instrumentos de medida específicos de la ansiedad escénica y del perfeccionismo por parte de 87 estudiantes del Conservatorio Superior de Música de Alicante. Resultados: Encontramos niveles de ansiedad escénica algo mayores a la media. La ansiedad escénica está relacionada significativamente con el perfeccionismo, y éste con las calificaciones del alumnado. Conclusiones: El perfeccionismo explica una parte tanto de la ansiedad escénica como de las calificaciones obtenidas por parte de los estudiantes. Es necesaria más investigación sobre la ansiedad escénica que suponga en un futuro implementar mejoras formativas.

    Full Text Available Cuando el artista flamenco sube al escenario, además de expresar su arte y disfrutar con su ejecución, es también objeto de la valoración de su público. Cuando los pensamientos y la atención del artista se centran solo en este escrutinio de la audiencia se puede desarrollar miedo o incomodidad a la hora de actuar, padeciendo lo que se denomina ansiedad escénica. Esta fobia social aparece cuando la persona teme ser evaluada negativamente por los demás y mostrar síntomas de nerviosismo que puedan ser perceptibles por el público. Las manifestaciones de la ansiedad se pueden clasificar en tres categorías: Cognitivas, fisiológicas y conductuales. Estas manifestaciones afectan al estado de ánimo, dificultan la ejecución de la tarea y predisponen al artista a evitar enfrentarse a futuras actuaciones. No controlar estas manifestaciones de la forma adecuada puede suponer en el músico o bailaor el detrimento de su calidad artística y en numerosas ocasiones, el abandono de la carrera artística. Estudios anteriores revelan que la formación académica y el contexto socio cultural en el que se desenvuelve el artista pueden incidir en el desarrollo y permanencia de la ansiedad escénica. Teniendo en cuenta las peculiaridades históricas y sociales del Flamenco así como la evolución de su formación, que ha pasado de la transmisión oral de un ambiente informal al estudio dentro de los conservatorios, se considera necesario estudiar cómo afecta la ansiedad a los artistas de este género para poder prevenir e intervenir en los músicos que la padezcan.

    2016-11-01

    Full Text Available This article provides new evidences in favour of the hypothesis that Cervantes, after finishing Don Quixote, Part II, partially revised the original, introducing some significant changes and additions, mainly in the last chapters. The analysis of some narrative inconsistencies, that cannot be interpreted as mere mistakes but as significant textual traces, reveals a process of re-elaboration –a process that affects at least four sections of the novel. Most of the evidence gathered here suggests that this revision is closely linked to Avellaneda’s continuation, in the sense that Cervantes tried to challenge the apocriphal Quixote making last-time interventions in his own text.

    Limited placement of real-time monitoring devices in the distribution grid, recent trends notwithstanding, has prevented the easy implementation of demand-response and other smart grid applications. Part I of this paper discusses the problem of learning the operational structure of the grid from nodal voltage measurements. In this work (Part II), the learning of the operational radial structure is coupled with the problem of estimating nodal consumption statistics and inferring the line parameters in the grid. Based on a Linear-Coupled(LC) approximation of AC power flows equations, polynomial time algorithms are designed to identify the structure and estimate nodal load characteristics and/or line parameters in the grid using the available nodal voltage measurements. Then the structure learning algorithm is extended to cases with missing data, where available observations are limited to a fraction of the grid nodes. The efficacy of the presented algorithms are demonstrated through simulations on several distribution test cases.

    The scope of this two-part review is to summarize publications dealing with CE and nanomaterials together. This topic can be viewed from two broad perspectives, and this article is trying to highlight these two approaches: (i) CE of nanomaterials, and (ii) nanomaterials in CE. The second part aims at summarization of publications dealing with application of nanomaterials for enhancement of CE performance either in terms of increasing the separation resolution or for improvement of the detection. To increase the resolution, nanomaterials are employed as either surface modification of the capillary wall forming open tubular column or as additives to the separation electrolyte resulting in a pseudostationary phase. Moreover, nanomaterials have proven to be very beneficial for increasing also the sensitivity of detection employed in CE or even they enable the detection (e.g., fluorescent tags of nonfluorescent molecules). © 2017 WILEY-VCH Verlag GmbH & Co.

    In Part I of this article, research on pseudocommandos was reviewed, and the important role that revenge fantasies play in motivating such persons to commit mass murder-suicide was discussed. Before carrying out their mass shootings, pseudocommandos may communicate some final message to the public or news media. These communications are rich sources of data about their motives and psychopathology. In Part II of this article, forensic psycholinguistic analysis is applied to clarify the primary motivations, detect the presence of mental illness, and discern important individual differences in the final communications of two recent pseudocommandos: Seung-Hui Cho (Virginia Tech) and Jiverly Wong (Binghamton, NY). Although both men committed offenses that qualify them as pseudocommandos, their final communications reveal striking differences in their psychopathology.

    As part of the U.S. Department of Energy's Low Wind Speed Turbine program, Global Energy Concepts LLC (GEC)1 has studied alternative composite materials for wind turbine blades in the multi-megawatt size range. This work in one of the Blade System Design Studies (BSDS) funded through Sandia National Laboratories. The BSDS program was conducted in two phases. In the Part I BSDS, GEC assessed candidate innovations in composite materials, manufacturing processes, and structural configurations. GEC also made recommendations for testing composite coupons, details, assemblies, and blade substructures to be carried out in the Part II study (BSDS-II). The BSDS-II contract period began in May 2003, and testing was initiated in June 2004. The current report summarizes the results from the BSDS-II test program. Composite materials evaluated include carbon fiber in both pre-impregnated and vacuum-assisted resin transfer molding (VARTM) forms. Initial thin-coupon static testing included a wide range of parameters, including variation in manufacturer, fiber tow size, fabric architecture, and resin type. A smaller set of these materials and process types was also evaluated in thin-coupon fatigue testing, and in ply-drop and ply-transition panels. The majority of materials used epoxy resin, with vinyl ester (VE) resin also used for selected cases. Late in the project, testing of unidirectional fiberglass was added to provide an updated baseline against which to evaluate the carbon material performance. Numerous unidirectional carbon fabrics were considered for evaluation with VARTM infusion. All but one fabric style considered suffered either from poor infusibility or waviness of fibers combined with poor compaction. The exception was a triaxial carbon-fiberglass fabric produced by SAERTEX. This fabric became the primary choice for infused articles throughout the test program. The generally positive results obtained in this program for the SAERTEX material have led to its

  2. Nursing as concrete philosophy, Part II: Engaging with reality.

    Science.gov (United States)

    Theodoridis, Kyriakos

    2018-04-01

    This is the second paper of an essay in two parts. The first paper (Part I) is a critical discussion of Mark Risjord's conception of nursing knowledge where I argued against the conception of nursing knowledge as a kind of nursing science. The aim of the present paper (Part II) is to explicate and substantiate the thesis of nursing as a kind of concrete philosophy. My strategy is to elaborate upon certain themes from Wittgenstein's Tractatus in order to canvass a general scheme of philosophy based on a distinction between reality and the world. This distinction will be employed in the appropriation of certain significant features of nursing and nursing knowledge. By elaborating on the contrast between the abstract and the concrete, I will suggest that nursing may be seen as a kind of concrete philosophy, being primarily concerned with reality (and secondarily with the world). This thesis, I will argue, implies that philosophy is the kind of theory that is essential to nursing (which is not so much a theory than a certain kind of activity). © 2017 John Wiley & Sons Ltd.

  3. Fast transforms for acoustic imaging--part II: applications.

    Ribeiro, Flávio P; Nascimento, Vítor H

    2011-08-01

    In Part I ["Fast Transforms for Acoustic Imaging-Part I: Theory," IEEE Transactions on Image Processing], we introduced the Kronecker array transform (KAT), a fast transform for imaging with separable arrays. Given a source distribution, the KAT produces the spectral matrix which would be measured by a separable sensor array. In Part II, we establish connections between the KAT, beamforming and 2-D convolutions, and show how these results can be used to accelerate classical and state of the art array imaging algorithms. We also propose using the KAT to accelerate general purpose regularized least-squares solvers. Using this approach, we avoid ill-conditioned deconvolution steps and obtain more accurate reconstructions than previously possible, while maintaining low computational costs. We also show how the KAT performs when imaging near-field source distributions, and illustrate the trade-off between accuracy and computational complexity. Finally, we show that separable designs can deliver accuracy competitive with multi-arm logarithmic spiral geometries, while having the computational advantages of the KAT.

    Full Text Available Female genital tuberculosis remains as a major cause of tubal obstruction leading to infertility, especially in developing countries. The global prevalence of genital tuberculosis has increased during the past two decades due to increasing acquired immunodeficiency syndrome. Genital tuberculosis (TB is commonly asymptomatic and it is diagnosed during infertility investigations. Despite of recent advances in imaging tools such as computed tomography (CT scan, magnetic resonance imaging (MRI and ultrasongraphy, hysterosalpingography has been considered as the standard screening test for evaluation of tubal infertility and as a valuable tool for diagnosis of female genital tuberculosis. Tuberculosis gives rise to various appearances on hysterosalpingography (HSG from non-specific changes to specific findings. The present pictorial review illustrates and describes specific and non-specific radiographic features of female genital tuberculosis in two parts. Part I presents specific findings of tuberculosis related to tubes such as "beaded tube", "golf club tube", "pipestem tube", "cobble stone tube" and the "leopard skin tube". Part II will describe adverse effects of tuberculosis on structure of endometrium and radiological specific findings, such as "T-shaped" tuberculosis uterus, "pseudo-unicornuate "uterus, "collar-stud abscess" and "dwarfed" uterus with lymphatic intravasation and occluded tubes which have not been encountered in the majority of non-tuberculosis cases.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Ansiedade pré-operatória é um fator negativo na experiência anestésico-cirúrgica. Dentre as estratégias para redução da ansiedade em crianças, as não farmacológicas são tão importantes quanto as farmacológicas, porém sua validade ainda é controversa. Verificar se a informação oferecida aos responsáveis interfere na ansiedade da criança. MÉTODOS: 72 crianças de 4 a 8 anos, ASA I e II, submetidas a procedimentos cirúrgicos eletivos e seus responsáveis, divididos aleatoriamente em: Grupo Controle (GC = responsável recebeu informação anestésica convencional; e Grupo Informativo (GI = responsável recebeu folheto sobre a anestesia. Foi avaliada ansiedade das crianças pela escala de ansiedade pré-operatória de Yale modificada (EAPY-m, em dois momentos, na sala de espera do centro cirúrgico (SE e na sala de operação (SO, e dos pais, pela Escala de ansiedade de Hamilton (HAM-A em SE. RESULTADOS: Não houve diferença nos dados sociodemográficos entre os grupos. O nível de ansiedade nas crianças não apresentou diferença entre os grupos nos dois momentos. Houve diferença estatística significativa nos níveis de ansiedade entre SE e SO nos dois grupos, p = 0,0019 no GC e p < 0,0001 no GI, assim como na prevalência de ansiedade em GC (SE 38,9% e SO 69,4%, p = 0,0174 e em GI (SE 19,4% e SO 83,3%, p< 0,0001. O nível de ansiedade dos responsáveis não apresentou diferença entre os grupos. CONCLUSÃO: Independentemente da qualidade de informação oferecida aos responsáveis, o nível e a prevalência de ansiedade das crianças foram baixos no momento SE e aumentaram significativamente no momento SO.

Se presentan los datos correspondientes a las respuestas de los pacientes a dos instrumentos de autorreporte acerca de la ansiedad ante los tratamientos odontológicos. Tanto la escala MDAS (Escala de Ansiedad Dental Modificada como la SDAI (Inventario de Ansiedad Dental-versión corta, permitieron identificar una distribución similar en los diferentes niveles de severidad en la muestra de este estudio. Adicionalmente, se pudo observar que los contextos más ansiogenos son los que incluyen jeringas y agujas (47,2%, la anticipación de la extracción de una pieza dental (34,7% y la anticipación del uso de la fresa dental (25,4%. Por otra parte, se observó niveles de ansiedad levemente mayores en mujeres que en hombres, este aspecto se evidencia tanto en los resultados de las escalas SDAI y MDAS como en la clasificación reportada por los odontólogos. Los resultados se discuten haciendo énfasis en la importancia de la identificación temprana de este desorden, del entrenamiento a odontólogos para su manejo; así como, del trabajo interdisciplinario para brindar al paciente una alternativa que promueva el uso de habilidades de autorregulación emocional.

    Full Text Available En este artículo se ha intentado mostrar una síntesis de los datos relativos a la influencia de los factores emocionales, específicamente la ansiedad y la depresión, en el proceso de salud-enfermedad. Estos factores se han asociado con las enfermedades crónicas como variables influyentes en el inicio, desarrollo y mantenimiento. Se han hipotetizado básicamente dos vías explicativas generales. La primera hace referencia a la influencia de la ansiedad y de la depresión en la conducta, de manera que interfieren en los hábitos saludables y fomentan el desarrollo de conductas inadecuadas que ponen en peligro nuestra salud. El segundo mecanismo se refiere a la repercusión de la activación psicofisiológica en los sistemas orgánicos, afectando a la inmunidad, por ejemplo. Pero no sólo existe una relación en el curso de la enfermedad, sino que también se conoce una alta comorbilidad de estas enfermedades con los trastornos ansiosos y depresivos, frecuentemente como consecuencia del padecimiento de las mismas. Por último, también se han revisado las intervenciones que han demostrado su eficacia en el tratamiento de la sintomatología ansiosa y depresiva en enfermos crónicos.

    2015-03-01

    Post-traumatic headache is one of the most common symptoms occurring after mild traumatic brain injury in children. This is an expert opinion-based two-part review on pediatric post-traumatic headaches. In part II, we focus on the medical management of post-traumatic headaches. There are no randomized controlled trials evaluating the efficacy of therapies specifically for pediatric post-traumatic headaches. Thus, the algorithm we propose has been extrapolated from the primary headache literature and small noncontrolled trials of post-traumatic headache. Most post-traumatic headaches are migraine or tension type, and standard medications for these headache types are used. A multifaceted approach is needed to address all the possible causes of headache and any comorbid conditions that may delay recovery or alter treatment choices. For acute treatment, nonsteroidal anti-inflammatories can be used. If the headaches have migrainous features and nonsteroidal anti-inflammatories are not effective, triptans may be beneficial. Opioids are not indicated. Medication overuse should be avoided. For preventive treatments, some reports indicate that amitriptyline, gabapentin, or topiramate may be beneficial. Amitriptyline is a good choice because it can be used to treat both migraine and tension-type headaches. Nerve blocks, nutraceuticals (e.g. melatonin), and behavioral therapies may also be useful, and lifestyle factors, especially adequate sleep hygiene and strategies to cope with anxiety, should be emphasized. Improved treatment of acute post-traumatic headache may reduce the likelihood of developing chronic headaches, which can be especially problematic to effectively manage and can be functionally debilitating.

    Full Text Available The present review summarizes the published literature examining cementation of the dowel and factors related to it. The peer reviewed English language literature was reviewed from the period 1990 to 2015. Articles were searched in Pubmed/ Medline for the relevant terms. Additional manual searches of some dental journals were also carried out. The original key terms resulted in 228 articles. After applying inclusion criteria, 64 articles remained to be included in part II of this review. Article search indicates that most published literature on dowels are in the form of in vitro analysis. Literature on prefabricated dowel systems far exceeds than the custom cast dowel and newer fibre dowels. Clinical evidence is not sufficient and cannot be used to inform practice confidently. However, within the limitations of this review it is suggested that adhesive fixation is preferred in case of short dowel. Dowel width should be as small as possible. A ferrule of 2 mm has to be provided. Composites have proven to be a good core material provided that adequate tooth structure remained for bonding. Dowel should be inserted if endodontically treated tooth is to be used as abutment for removable partial dentures.

    2013-02-01

    In this Part II psychiatric disorders coexisting with organic diseases are discussed. "Comorbidity phenomenon" defines the not univocal interrelation between medical illnesses and psychiatric disorders, each other negatively influencing morbidity and mortality. Most severe psychiatric disorders, such as schizophrenia, bipolar disorder and depression, show increased prevalence of cardiovascular disease, related to poverty, use of psychotropic medication, and higher rate of preventable risk factors such as smoking, addiction, poor diet and lack of exercise. Moreover, psychiatric and organic disorders can develop together in different conditions of toxic substance and prescription drug use or abuse, especially in the emergency setting population. Different combinations with mutual interaction of psychiatric disorders and substance use disorders are defined by the so called "dual diagnosis". The hypotheses that attempt to explain the psychiatric disorders and substance abuse relationship are examined: (1) common risk factors; (2) psychiatric disorders precipitated by substance use; (3) psychiatric disorders precipitating substance use (self-medication hypothesis); and (4) synergistic interaction. Diagnostic and therapeutic difficulty concerning the problem of dual diagnosis, and legal implications, are also discussed. Substance induced psychiatric and organic symptoms can occur both in the intoxication and withdrawal state. Since ancient history, humans selected indigene psychotropic plants for recreational, medicinal, doping or spiritual purpose. After the isolation of active principles or their chemical synthesis, higher blood concentrations reached predispose to substance use, abuse and dependence. Abuse substances have specific molecular targets and very different acute mechanisms of action, mainly involving dopaminergic and serotoninergic systems, but finally converging on the brain's reward pathways, increasing dopamine in nucleus accumbens.

El tema es tan complejo que un intento por resumirlo de por sí ya es atrayente además de necesario.

    Microhistoria de la lA. Ciñéndome a una cruda realidad la lA nació en la Conferencia de Darmouth, año 1956, cuando John McCarthy, profesor de ciencia de computador en Stanford Un. acuñó el término de lA. Sin embargo, especulando un poco podemos decir que cierta inquietud existió desde la antigüedad, mucho antes de los computadores y aún de la electrónica (1 cuando el ser humano irresistiblemente mostraba inquietud por crear I fuera del cerebro humano. Se encuentran algunos ejemplos en la Mitología griega: Hefestos. dios del fuego y de los metales, confeccionaba creaciones semihumanas en su forja. Pigmalión desencantado de las mujeres modeló su propia ninfa en mármol y para poder casarse con ella imploró suplicante hasta conseguir que Afrodita le diera vida.

  6. [Low grade renal trauma (Part II): diagnostic validity of ultrasonography].

    Grill, R; Báca, V; Otcenásek, M; Zátura, F

    2010-04-01

    The aim of the study was to verify whether ultrasonography can be considered a reliable method for the diagnosis of low-grade renal trauma. The group investigated included patients with grade I or grade II blunt renal trauma, as classified by the AAST grading system, in whom ultrasonography alone or in conjunction with computed tomography was used as a primary diagnostic method. B-mode ultrasound with a transabdominal probe working at frequencies of 2.5 to 5.0 MHz was used. Every finding of post-traumatic changes in the renal tissues, i.e., post-contusion hypotonic infiltration of the renal parenchyma or subcapsular haematoma, was included. The results were statistically evaluated by the Chi-square test with the level of significance set at 5%, using Epi Info Version 6 CZ software. The group comprised 112 patients (43 women, 69 men) aged between 17 and 82 years (average, 38 years). It was possible to diagnose grade I or grade II renal injury by ultrasonography in only 60 (54%) of them. The statistical significance of ultrasonography as the only imaging method for the diagnosis of low-grade renal injury was not confirmed (p=0.543) Low-grade renal trauma is a problem from the diagnostic point of view. It usually does not require revision surgery and, if found during repeat surgery for more serious injury of another organ, it usually does not receive attention. Therefore, the macroscopic presentation of grade I and grade II renal injury is poorly understood, nor are their microscopic findings known, because during revision surgery these the traumatised kidneys are not usually removed and their injuries at autopsy on the patients who died of multiple trauma are not recorded either. The results of this study demonstrated that the validity of ultrasonography for the diagnosis of low-grade renal injury is not significant, because this examination can reveal only some of the renal injuries such as perirenal haematoma. An injury to the renal parenchyma is also indicated by

  7. Lagrangian intersection Floer theory anomaly and obstruction, part II

    CERN Document Server

    Fukaya, Kenji; Ohta, Hiroshi; Ono, Kaoru

    2009-01-01

    This is a two-volume series research monograph on the general Lagrangian Floer theory and on the accompanying homological algebra of filtered A_\\infty-algebras. This book provides the most important step towards a rigorous foundation of the Fukaya category in general context. In Volume I, general deformation theory of the Floer cohomology is developed in both algebraic and geometric contexts. An essentially self-contained homotopy theory of filtered A_\\infty algebras and A_\\infty bimodules and applications of their obstruction-deformation theory to the Lagrangian Floer theory are presented. Volume II contains detailed studies of two of the main points of the foundation of the theory: transversality and orientation. The study of transversality is based on the virtual fundamental chain techniques (the theory of Kuranishi structures and their multisections) and chain level intersection theories. A detailed analysis comparing the orientations of the moduli spaces and their fiber products is carried out. A self-co...

  12. The equivalence myth of quantum mechanics-part II

    Science.gov (United States)

    Muller, F. A.

    The author endeavours to show two things: first, that Schrödingers (and Eckarts) demonstration in March (September) 1926 of the equivalence of matrix mechanics, as created by Heisenberg, Born, Jordan and Dirac in 1925, and wave mechanics, as created by Schrödinger in 1926, is not foolproof; and second, that it could not have been foolproof, because at the time matrix mechanics and wave mechanics were neither mathematically nor empirically equivalent. That they were is the Equivalence Myth. In order to make the theories equivalent and to prove this, one has to leave the historical scene of 1926 and wait until 1932, when von Neumann finished his magisterial edifice. During the period 1926-1932 the original families of mathematical structures of matrix mechanics and of wave mechanics were stretched, parts were chopped off and novel structures were added. To Procrustean places we go, where we can demonstrate the mathematical, empirical and ontological equivalence of 'the final versions of' matrix mechanics and wave mechanics. The present paper claims to be a comprehensive analysis of one of the pivotal papers in the history of quantum mechanics: Schrödingers equivalence paper. Since the analysis is performed from the perspective of Suppes structural view ('semantic view') of physical theories, the present paper can be regarded not only as a morsel of the internal history of quantum mechanics, but also as a morsel of applied philosophy of science. The paper is self-contained and presupposes only basic knowledge of quantum mechanics. For reasons of length, the paper is published in two parts; Part I appeared in the previous issue of this journal. Section 1 contains, besides an introduction, also the papers five claims and a preview of the arguments supporting these claims; so Part I, Section 1 may serve as a summary of the paper for those readers who are not interested in the detailed arguments.

    2013-02-01

    Full Text Available The viscosity of slag and the thermal conductivity of ash deposits are among two of the most important constitutive parameters that need to be studied. The accurate formulation or representations of the (transport properties of coal present a special challenge of modeling efforts in computational fluid dynamics applications. Studies have indicated that slag viscosity must be within a certain range of temperatures for tapping and the membrane wall to be accessible, for example, between 1,300 °C and 1,500 °C, the viscosity is approximately 25 Pa·s. As the operating temperature decreases, the slag cools and solid crystals begin to form. Since slag behaves as a non-linear fluid, we discuss the constitutive modeling of slag and the important parameters that must be studied. We propose a new constitutive model, where the stress tensor not only has a yield stress part, but it also has a viscous part with a shear rate dependency of the viscosity, along with temperature and concentration dependency, while allowing for the possibility of the normal stress effects. In Part I, we reviewed, identify and discuss the key coal ash properties and the operating conditions impacting slag behavior.

  16. Underwater Electromagnetic Sensor Networks, Part II: Localization and Network Simulations

    2016-12-01

    Full Text Available In the first part of the paper, we modeled and characterized the underwater radio channel in shallowwaters. In the second part,we analyze the application requirements for an underwaterwireless sensor network (U-WSN operating in the same environment and perform detailed simulations. We consider two localization applications, namely self-localization and navigation aid, and propose algorithms that work well under the specific constraints associated with U-WSN, namely low connectivity, low data rates and high packet loss probability. We propose an algorithm where the sensor nodes collaboratively estimate their unknown positions in the network using a low number of anchor nodes and distance measurements from the underwater channel. Once the network has been self-located, we consider a node estimating its position for underwater navigation communicating with neighboring nodes. We also propose a communication system and simulate the whole electromagnetic U-WSN in the Castalia simulator to evaluate the network performance, including propagation impairments (e.g., noise, interference, radio parameters (e.g., modulation scheme, bandwidth, transmit power, hardware limitations (e.g., clock drift, transmission buffer and complete MAC and routing protocols. We also explain the changes that have to be done to Castalia in order to perform the simulations. In addition, we propose a parametric model of the communication channel that matches well with the results from the first part of this paper. Finally, we provide simulation results for some illustrative scenarios.

  18. Hermeneutics as an approach to science: Part II

    Science.gov (United States)

    Eger, Martin

    1993-12-01

    This paper continues the hermeneutic-phenomenological investigation of natural science, in which understanding plays a role comparable to creative construction (see ‘Hermeneutics as an Approach to Science: Part I’ in Science & Education 2(1)). The first issue treated is that of language: Is the language of science part of the equipment of the scientist, the subject, or part of the object itself — nature already linguistically encased? This issue, arising from the so-called argument of ‘the double hermeneutic’, relates the general question of the role of the subject in natural science to the role of interpretation. Examples of major interpretative developments in physics are discussed. The inquiry suggests that the role of interpretation and hermeneutics is tied to the educative or ‘study-mode’ of science; and that this mode can, apparently, be found at all levels and stages of science. The nature of this interpretive mode, and its relation to the creative mode, is then analyzed on the model of Gadamer's description of the interpretation of art.

    This paper analyses the design of carbon markets in space (i.e., geographically). It is part of a twin set of papers that, starting from first principles, ask what an optimal global carbon market would look like by around 2030. Our focus is on firm-level cap-and-trade systems, although much of what we say would also apply to government-level trading and carbon offset schemes. We examine the 'first principles' of spatial design to maximise flexibility and to minimise costs, including key design issues in linking national and regional carbon markets together to create a global carbon market.

  9. Nanoparticles and the blood coagulation system. Part II: safety concerns

    Science.gov (United States)

    Ilinskaya, Anna N; Dobrovolskaia, Marina A

    2014-01-01

    Nanoparticle interactions with the blood coagulation system can be beneficial or adverse depending on the intended use of a nanomaterial. Nanoparticles can be engineered to be procoagulant or to carry coagulation-initiating factors to treat certain disorders. Likewise, they can be designed to be anticoagulant or to carry anticoagulant drugs to intervene in other pathological conditions in which coagulation is a concern. An overview of the coagulation system was given and a discussion of a desirable interface between this system and engineered nanomaterials was assessed in part I, which was published in the May 2013 issue of Nanomedicine. Unwanted pro- and anti-coagulant properties of nanoparticles represent significant concerns in the field of nanomedicine, and often hamper the development and transition into the clinic of many promising engineered nanocarriers. This part will focus on the undesirable effects of engineered nanomaterials on the blood coagulation system. We will discuss the relationship between the physicochemical properties of nanoparticles (e.g., size, charge and hydrophobicity) that determine their negative effects on the blood coagulation system in order to understand how manipulation of these properties can help to overcome unwanted side effects.

    2015-05-01

    The diagnosis of disorders of the hair and scalp can generally be made on clinical grounds, but clinical signs are not always diagnostic and in some cases more invasive techniques, such as a biopsy, may be necessary. This 2-part article is a detailed review of the histologic features of the main types of alopecia based on the traditional classification of these disorders into 2 major groups: scarring and nonscarring alopecias. Scarring alopecias are disorders in which the hair follicle is replaced by fibrous scar tissue, a process that leads to permanent hair loss. In nonscarring alopecias, the follicles are preserved and hair growth can resume when the cause of the problem is eliminated. In the second part of this review, we describe the histologic features of the main forms of scarring alopecia. Since a close clinical-pathological correlation is essential for making a correct histopathologic diagnosis of alopecia, we also include a brief description of the clinical features of the principal forms of this disorder.

  11. Complex dynamics in diatomic molecules. Part II: Quantum trajectories

    International Nuclear Information System (INIS)

    Yang, C.-D.; Weng, H.-J.

    2008-01-01

    The second part of this paper deals with quantum trajectories in diatomic molecules, which has not been considered before in the literature. Morse potential serves as a more accurate function than a simple harmonic oscillator for illustrating a realistic picture about the vibration of diatomic molecules. However, if we determine molecular dynamics by integrating the classical force equations derived from a Morse potential, we will find that the resulting trajectories do not consist with the probabilistic prediction of quantum mechanics. On the other hand, the quantum trajectory determined by Bohmian mechanics [Bohm D. A suggested interpretation of the quantum theory in terms of hidden variable. Phys. Rev. 1952;85:166-179] leads to the conclusion that a diatomic molecule is motionless in all its vibrational eigen-states, which also contradicts probabilistic prediction of quantum mechanics. In this paper, we point out that the quantum trajectory of a diatomic molecule completely consistent with quantum mechanics does exist and can be solved from the quantum Hamilton equations of motion derived in Part I, which is based on a complex-space formulation of fractal spacetime [El Naschie MS.

    Full Text Available The Holy and Great Council on Crete, 2016 has risen an important issue of Ethnophyletism. Russian, Georgian, Bulgarian, and Antiochian Orthodox Churches delegations were not present at the Great Council and were criticized for Ethnophyletism at the plenary session. The heresy of ethnophyletism was announced by the Council of Constantinople in 1872. Now we can see that it became essential nowadays. The article tells about the origin of this heresy and whether the Ethnophyletism may be decided to be the heresy. The second part of the paper deals with the events on the eve of the Pan-Orthodox Synod in 1872 (since the manifestation of the famous Abdülaziz Sultan's Firman 1870.

    In this paper we continue and improve the analysis of the effective actions obtained by integrating out a scalar and a fermion field coupled to external symmetric sources, started in the previous paper. The first subject we study is the geometrization of the results obtained there, that is we express them in terms of covariant Jacobi tensors. The second subject concerns the treatment of tadpoles and seagull terms in order to implement off-shell covariance in the initial model. The last and by far largest part of the paper is a repository of results concerning all two point correlators (including mixed ones) of symmetric currents of any spin up to 5 and in any dimensions between 3 and 6. In the massless case we also provide formulas for any spin in any dimension.

    This paper is a continuation of the work presented in SAND2007-2591 'Planar LTCC Transformers for High Voltage Flyback Converters'. The designs in that SAND report were all based on a ferrite tape/dielectric paste system originally developed by NASCENTechnoloy, Inc, who collaborated in the design and manufacturing of the planar LTCC flyback converters. The output/volume requirements were targeted to DoD application for hard target/mini fuzing at around 1500 V for reasonable primary peak currents. High voltages could be obtained but with considerable higher current. Work had begun on higher voltage systems and is where this report begins. Limits in material properties and processing capabilities show that the state-of-the-art has limited our practical output voltage from such a small part volume. In other words, the technology is currently limited within the allowable funding and interest.

All these types of diseases have similar clinical signs, but differ by prevalence, prognosis and medical tactics. Due to achievements of radial methods of visualization, molecular biology, and immunology, we have an opportunity to provide early specific diagnostics and etiological treatment of inflammatory diseases of pericardium. The second part of lecture presents main principles of differential diagnostics of specific types of pericarditis, gives characteristics of several often accruing types of disease, and describes treatment and tactics of management of patients with pericarditis.Key words: children, pericarditis.(Voprosy sovremennoi pediatrii — Current Pediatrics. 2009;8(3:76-81

  16. [Scientific reductionism and social control of mind. Part II].

    Viniegra Velázquez, Leonardo

    In the second part of this essay, the progressive subordination of scientific endeavor and knowledge of business and profit is pointed out. For instance, the way facts are prioritized over concepts and ideas in scientific knowledge can translate into technological innovation, central to enterprise competitiveness and key to social mechanisms of control (military, cybernetic, ideological). Overcoming the scientific reductionism approach indicates recognizing the need to define progress in another way, one that infuses scientific knowledge with real liberating and inquisitive power. Power is essential in the search for a more collaborative, inclusive and pluralistic society where respect for human dignity and care for the ecosystem that we live in are prioritized.

    2005-01-01

    Part two of this series discussed the key strategies that each practice should focus on for caries management. History has proven that oral hygiene and "drilling and filling" alone will not eliminate dental caries. Chemical treatments to prevent and reverse early lesions and conservative, tooth-preserving restorative procedures when surgical intervention is necessary should be the new standard of care. Caries management by risk assessment (CAMBRA), where risk factors are "re-balanced" to that of health, is a sound strategy that is one step closer to "curative" dentistry and improving the quality of life of dental patients. The final article in this series will discuss the role that glass-ionomer materials and hard tissue lasers play in the minimally invasive restorative procedures for dental caries.

    A growing percentage of physicians are selecting employment over solo practice, and fewer family physicians have hospital admission privileges. Results from surveys of recent medical school graduates indicate a high value placed on free time. Factors to consider when choosing a practice opportunity include desire for independence, decision-making authority, work-life balance, administrative responsibilities, financial risk, and access to resources. Compensation models are evolving from the simple fee-for-service model to include metrics that reward panel size, patient access, coordination of care, chronic disease management, achievement of patient-centered medical home status, and supervision of midlevel clinicians. When a practice is sold, tangible personal property and assets in excess of liabilities, patient accounts receivable, office building, and goodwill (ie, expected earnings) determine its value. The sale of a practice includes a broad legal review, addressing billing and coding deficiencies, noncompliant contractual arrangements, and potential litigations as well as ensuring that all employment agreements, leases, service agreements, and contracts are current, have been executed appropriately, and meet regulatory requirements.

    Patent law and antitrust law have traditionally been areas of the law involving at least some inherent tension. Champions of antitrust argue that the patent “monopoly” must be strictly limited as an exception to the general legal principle that competition should be unfettered. Patent lawyers argue that patents are the result of an exercise of congressional authority, enshrined in the Constitution, reflecting the policy decision by the Founders that granting a limited exclusionary right was justified by the public benefits derived from full disclosure of the patented invention. In the modern era these competing values have played out in the context of so-called ANDA litigation, involving disputes between branded pharmaceutical companies and generic competitors. Settlement of such litigation has been identified by the Federal Trade Commission (FTC), and private parties encouraged by the FTC’s position, as an antitrust violation, in large part because such settlements are viewed as frustrating the congressional purpose in promoting early generic competition. After almost a decade of fighting these battles in the federal courts, the Supreme Court addressed the issue directly. The result is that such settlements are not per se illegal but are also not protected by the presumption of patent validity for activities within the “scope of the patent.” Rather, the court decided that these agreements should be assessed for antitrust liability under the “rule of reason” used in other antitrust contexts.

    2013-04-01

    Full Text Available Introduction: Positron-emission tomography (PET and single photon emission computed tomography (SPECT are effective diagnostic imaging tools in several clinical settings. The aim of this article (the second of a 2-part series is to examine some of the more recent applications of nuclear medicine imaging techniques, particularly in the fields of neurology, cardiology, and infection/inflammation. Discussion: A review of the literature reveals that in the field of neurology nuclear medicine techniques are most widely used to investigate cognitive deficits and dementia (particularly those associated with Alzheimer disease, epilepsy, and movement disorders. In cardiology, SPECT and PET also play important roles in the work-up of patients with coronary artery disease, providing accurate information on the state of the myocardium (perfusion, metabolism, and innervation. White blood cell scintigraphy and FDG-PET are widely used to investigate many infectious/inflammatory processes. In each of these areas, the review discusses the use of recently developed radiopharmaceuticals, the growth of tomographic nuclear medicine techniques, and the ways in which these advances are improving molecular imaging of biologic processes at the cellular level.

  5. Imaging of juvenile idiopathic arthritis. Part II: Ultrasonography and MRI

    2016-09-01

    Full Text Available Juvenile idiopathic arthritis is the most common autoimmune systemic disease of the connective tissue affecting individuals in the developmental age. Radiography, which was described in the first part of this publication, is the standard modality in the assessment of this condition. Ultrasound and magnetic resonance imaging enable early detection of the disease which affects soft tissues, as well as bones. Ultrasound assessment involves: joint cavities, tendon sheaths and bursae for the presence of synovitis, intraand extraarticular fat tissue to visualize signs of inflammation, hyaline cartilage, cartilaginous epiphysis and subchondral bone to detect cysts and erosions, and ligaments, tendons and their entheses for signs of enthesopathies and tendinopathies. Magnetic resonance imaging is indicated in children with juvenile idiopathic arthritis for assessment of inflammation in peripheral joints, tendon sheaths and bursae, bone marrow involvement and identification of inflammatory lesions in whole-body MRI, particularly when the clinical picture is unclear. Also, MRI of the spine and spinal cord is used in order to diagnose synovial joint inflammation, bone marrow edema and spondylodiscitis as well as to assess their activity, location, and complications (spinal canal stenosis, subluxation, e.g. in the atlantoaxial region. This article discusses typical pathological changes seen on ultrasound and magnetic resonance imaging. The role of these two methods for disease monitoring, its identification in the pre-clinical stage and establishing its remission are also highlighted.

    This study applies generalized polynomial chaos theory to model complex nonlinear multibody dynamic systems operating in the presence of parametric and external uncertainty. Theoretical and computational aspects of this methodology are discussed in the companion paper 'Modeling Multibody Dynamic Systems With Uncertainties. Part I: Theoretical and Computational Aspects .In this paper we illustrate the methodology on selected test cases. The combined effects of parametric and forcing uncertainties are studied for a quarter car model. The uncertainty distributions in the system response in both time and frequency domains are validated against Monte-Carlo simulations. Results indicate that polynomial chaos is more efficient than Monte Carlo and more accurate than statistical linearization. The results of the direct collocation approach are similar to the ones obtained with the Galerkin approach. A stochastic terrain model is constructed using a truncated Karhunen-Loeve expansion. The application of polynomial chaos to differential-algebraic systems is illustrated using the constrained pendulum problem. Limitations of the polynomial chaos approach are studied on two different test problems, one with multiple attractor points, and the second with a chaotic evolution and a nonlinear attractor set. The overall conclusion is that, despite its limitations, generalized polynomial chaos is a powerful approach for the simulation of multibody dynamic systems with uncertainties.

    Full Text Available In the recent years there has been a particularly strong pressure on changing old structures and management models in research institutes. Contemporary research institutes are scientific units which are commercial in character – almost 80% of funds come from companies and contractual research activity and services. They are the basic sector of science aiming at cooperation with the economy, applied and innovative research. In order to maintain the current and start new cooperation it is necessary to pay particular attention to maintaining, improving and exposing high level of quality of conducted activity. Taking into consideration the necessity of carrying out ever more complex research projects, conducting activity requiring fast reaction to change, risk analysis, which is assessed every year by the Ministry of Science and Higher Education – it seems that it is necessary to apply tools supporting the assessment of quality. In the proposed three-aspect perspective the following scopes of activity are emphasized: implemented quality management systems, area of scientific information and the sphere of cooperation with the client. This article constitutes the continuation of the subjects discussed in the first part – an extension of issues associated with the scope of responsibilities of particular Sections of the proposed Quality Management Platform in research institutes.

    2017-06-12

    This study reports cyclopentane ignition delay measurements over a wide range of conditions. The measurements were obtained using two shock tubes and a rapid compression machine, and were used to test a detailed low- and high-temperature mechanism of cyclopentane oxidation that was presented in part I of this study (Al Rashidi et al., 2017). The ignition delay times of cyclopentane/air mixtures were measured over the temperature range of 650–1350K at pressures of 20 and 40atm and equivalence ratios of 0.5, 1.0 and 2.0. The ignition delay times simulated using the detailed chemical kinetic model of cyclopentane oxidation show very good agreement with the experimental measurements, as well as with the cyclopentane ignition and flame speed data available in the literature. The agreement is significantly improved compared to previous models developed and investigated at higher temperatures. Reaction path and sensitivity analyses were performed to provide insights into the ignition-controlling chemistry at low, intermediate and high temperatures. The results obtained in this study confirm that cycloalkanes are less reactive than their non-cyclic counterparts. Moreover, cyclopentane, a high octane number and high octane sensitivity fuel, exhibits minimal low-temperature chemistry and is considerably less reactive than cyclohexane. This study presents the first experimental low-temperature ignition delay data of cyclopentane, a potential fuel-blending component of particular interest due to its desirable antiknock characteristics.

    Full Text Available A short review of biopolymers based on starch (starch derivatives, thermoplastic starch, lignin and hemicelluloses, chitin (chitosan and products obtained by degradation of starch and other polysaccharides and sugars (poly(lactic acid, poly(hydroxyalkanoates, as well as some of their basic properties and application area, are given in this part. The problem of environmental and economic feasibility of biopolymers based on renewable raw materials and their competitiveness with polymers based on fossil raw materials is discussed. Also pointed out are the problems that appear due to the increasing use of agricultural land for the production of raw materials for the chemical industry and energy, instead for the production of food for humans and animals. The optimistic assessments of experts considering the development perspectives of biopolymers based on renewable raw materials in the next ten years have also been pointed out.At the end of the paper, the success of a team of researchers gathered around the experts from the company Bayer is indicated. They were the first in the world to develop a catalyst by which they managed to effectively activate CO - and incorporate it into polyols, used for the synthesis of polyurethanes in semi-industrial scale. By applying this process, for the first time a pollutant will be used as a basic raw material for the synthesis of organic compounds, which will have significant consequences on the development of the chemical industry, and therefore the production of polymers.

    2008-08-01

    Full Text Available The concepts of health promotion, self-care and community participation emerged during the 1970s and, since then, their application has grown rapidly in the developed world, showing evidence of effectiveness. In spite of this, a major part of the population in the developing countries still has no access to specialized dental care such as endodontic treatment, dental care for patients with special needs, minor oral surgery, periodontal treatment and oral diagnosis. This review focuses on a program of the Brazilian Federal Government named CEOs (Dental Specialty Centers, which is an attempt to solve the dental care deficit of a population that is suffering from oral diseases and whose oral health care needs have not been addressed by the regular programs offered by the SUS (Unified National Health System. Literature published from 2000 to the present day, using electronic searches by Medline, Scielo, Google and hand-searching was considered. The descriptors used were Brazil, Oral health, Health policy, Health programs, and Dental Specialty Centers. There are currently 640 CEOs in Brazil, distributed in 545 municipal districts, carrying out dental procedures with major complexity. Based on this data, it was possible to conclude that public actions on oral health must involve both preventive and curative procedures aiming to minimize the oral health distortions still prevailing in developing countries like Brazil.

    2015-12-01

    Full Text Available The paper attempts to justify an alternative to conventional methodology of economics, as well as make a corresponding revision of the history of this discipline. It explains why the discipline in its orthodox version, and for the most unorthodox directions, is cognitively sterile and socio-economico-politically very harmful. The paper can be seen as a manifesto which calls for a radical change in the discipline. As a manifesto, it probably could be called "Economics: from repentance and resurrection", that is, I suggest to economists to repent of the harm that this discipline has brought and on the basis of this reflection to revive it in the different methodological framework that is able to make economics socially useful. The second part of the paper, which is published in this issue, consists of two sections. In the first one (section number 4 economics is regarded as an institution and discusses its origin and evolution, as well as its current operation. On the basis of the analysis made in this section we can conclude that this institution has a very high degree of stability and because of that it cannot be reformed without an active external intervention. The fifth section of the paper is devoted to the link of the social role of economics with its methodology. It argues that the social function of economic science is the study of reality as it is, and underlines that economic education must be oriented in this direction.

    Maloney, C

    1985-01-01

    Bangladeshis of varying background all over the country were asked why they think poverty persists to such an extent in Bangladesh. Their answers provide a new perspective on the situation. The initial response often blames outside and natural causes -- floods, droughts, lack of resources, low demand for the country's exports, or historic exploitation. It is true that Bangladesh has virtually no mineral resources except gas. Yet, the soil, water, and human labor add up to a huge potential. The Third Five Year Plan emphasizes use of the soil, irrigation, tanks, rivers, and human labor. These provide the only hope for reducing poverty a little during the next 5 years. Bangladeshis as well as foreign observers most commonly cite overpopulation as the cause of poverty. Population growth is a cause of present poverty in Bangladesh but is not the only cause of poverty. The Third Five Year Plan goal to reduce annual growth to 1.8% is ambitious, but even if it is achieved the population will double in a few decades. As it would most likely be impossible for Bangladesh to support such numbers and maintain political and economic stability, such growth will have to be prevented. Poverty in Bangladesh is party a result of the long history of low urbanization, weak institutions, spotty and inadequate physical infrastructure, and insufficient entrapreneurship. Other reasons cited as causes of persisting poverty include illiteracy, idleness, class exploitation, the selfishness of individuals, and a lack of trust among people. All of the efforts of the poor themselves, various agencies, and the government, as examined in the 1st part of this discussion, fail to indicate any reason to hope that poverty in Bangladesh can be dramatically reduced any time soon. The Third Five Year Plan foresees a possible reduction of the number of those in poverty by 10%. According to the Plan itself, those in or near poverty comprise 85% of the people. The conditions under which the people of some

    ABSTRACT Traditionally, the treatment of overactive bladder syndrome has been based on the use of oral medications with the purpose of reestablishing the detrusor stability. The recent better understanding of the urothelial physiology fostered conceptual changes, and the oral anticholinergics – pillars of the overactive bladder pharmacotherapy – started to be not only recognized for their properties of inhibiting the detrusor contractile activity, but also their action on the bladder afference, and therefore, on the reduction of the symptoms that constitute the syndrome. Beta-adrenergic agonists, which were recently added to the list of drugs for the treatment of overactive bladder, still wait for a definitive positioning – as either a second-line therapy or an adjuvant to oral anticholinergics. Conservative treatment failure, whether due to unsatisfactory results or the presence of adverse side effects, define it as refractory overactive bladder. In this context, the intravesical injection of botulinum toxin type A emerged as an effective option for the existing gap between the primary measures and more complex procedures such as bladder augmentation. Sacral neuromodulation, described three decades ago, had its indication reinforced in this overactive bladder era. Likewise, the electric stimulation of the tibial nerve is now a minimally invasive alternative to treat those with refractory overactive bladder. The results of the systematic literature review on the oral pharmacological treatment and the treatment of refractory overactive bladder gave rise to this second part of the review article Overactive Bladder – 18 years, prepared during the 1st Latin-American Consultation on Overactive Bladder.

    We studied the fundamentals of muscle afferentation by building a Neuro-mechano-morphic system actuating a cadaveric finger. This system is a faithful implementation of the stretch reflex circuitry. It allowed the systematic exploration of the effects of different fusimotor drives to the muscle spindle on the closed-loop stretch reflex response. As in Part I of this work, sensory neurons conveyed proprioceptive information from muscle spindles (with static and dynamic fusimotor drive) to populations of α-motor neurons (with recruitment and rate coding properties). The motor commands were transformed into tendon forces by a Hill-type muscle model (with activation-contraction dynamics) via brushless DC motors. Two independent afferented muscles emulated the forces of flexor digitorum profundus and the extensor indicis proprius muscles, forming an antagonist pair at the metacarpophalangeal joint of a cadaveric index finger. We measured the physical response to repetitions of bi-directional ramp-and-hold rotational perturbations for 81 combinations of static and dynamic fusimotor drives, across four ramp velocities, and three levels of constant cortical drive to the α-motor neuron pool. We found that this system produced responses compatible with the physiological literature. Fusimotor and cortical drives had nonlinear effects on the reflex forces.

    Objective. We studied the fundamentals of muscle afferentation by building a Neuro-mechano-morphic system actuating a cadaveric finger. This system is a faithful implementation of the stretch reflex circuitry. It allowed the systematic exploration of the effects of different fusimotor drives to the muscle spindle on the closed-loop stretch reflex response. Approach. As in Part I of this work, sensory neurons conveyed proprioceptive information from muscle spindles (with static and dynamic fusimotor drive) to populations of α-motor neurons (with recruitment and rate coding properties).

  4. PGE Production in Southern Africa, Part II: Environmental Aspects

    Full Text Available Platinum group elements (PGEs, 6E PGE = Pt + Pd + Rh + Ru + Ir + Au are used in numerous applications that seek to reduce environmental impacts of mobility and energy generation. Consequently, the future demand for PGEs is predicted to increase. Previous studies indicate that environmental impacts of PGE production change over time emphasizing the need of up-to-date data and assessments. In this context, an analysis of environmental aspects of PGE production is needed to support the environmental assessment of technologies using PGEs, to reveal environmental hotspots within the production chain and to identify optimization potential. Therefore, this paper assesses greenhouse gas (GHG emissions, cumulative fossil energy demand (CEDfossil, sulfur dioxide (SO2 emissions and water use of primary PGE production in Southern Africa, where most of today’s supply originates from. The analysis shows that in 2015, emissions amounted to 45 t CO2-eq. and 502 kg SO2 per kg 6E PGE in the case GHG and SO2 emissions, respectively. GHG emissions are dominated by emissions from electricity provision contributing more than 90% to the overall GHG emissions. The CEDfossil amounted to 0.60 TJ per kg 6E PGE. A detailed analysis of the CEDfossil reveals that electricity provision based on coal power consumes the most fossil energy carriers among all energy forms. Results show that the emissions are directly related to the electricity demand. Thus, the reduction in the electricity demand presents the major lever to reduce the consumption of fossil energy resources and the emission of GHGs and SO2. In 2015, the water withdrawal amounted to 0.272 million L per kg 6E PGE. Additionally, 0.402 million L of recycled water were used per kg 6E PGE. All assessed indicators except ore grades and production volumes reveal increasing trends in the period from 2010 to 2015. It can be concluded that difficult market conditions (see part I of this paper series and increasing

  5. PROBABILITY BASED CORROSION CONTROL FOR WASTE TANKS - PART II

    Energy Technology Data Exchange (ETDEWEB)

    Hoffman, E.; Edwards, T.

    2010-12-09

    As part of an ongoing study to evaluate the discontinuity in the corrosion controls at the SRS tank farm, a study was conducted this year to assess the minimum concentrations below 1 molar nitrate, see Figure 1. Current controls on the tank farm solution chemistry are in place to prevent the initiation and propagation of pitting and stress corrosion cracking in the primary steel waste tanks. The controls are based upon a series of experiments performed with simulated solutions on materials used for construction of the tanks, namely ASTM A537 carbon steel (A537). During FY09, an experimental program was undertaken to investigate the risk associated with reducing the minimum molar nitrite concentration required to confidently inhibit pitting in dilute solutions (i.e., less than 1 molar nitrate). The experimental results and conclusions herein provide a statistical basis to quantify the probability of pitting for the tank wall exposed to various solutions with dilute concentrations of nitrate and nitrite. Understanding the probability for pitting will allow the facility to make tank-specific risk-based decisions for chemistry control. Based on previous electrochemical testing, a statistical test matrix was developed to refine and solidify the application of the statistical mixture/amount model to corrosion of A537 steel. A mixture/amount model was identified based on statistical analysis of recent and historically collected electrochemical data. This model provides a more complex relationship between the nitrate and nitrite concentrations and the probability of pitting than is represented by the model underlying the current chemistry control program, and its use may provide a technical basis for the utilization of less nitrite to inhibit pitting at concentrations below 1 molar nitrate. FY09 results fit within the mixture/amount model, and further refine the nitrate regime in which the model is applicable. The combination of visual observations and cyclic

    Full Text Available La menopausia es la interrupción definitiva de las menstruaciones resultado de la pérdida de la actividad folicular del ovario. El periodo inmediatamente antes de la menopausia y el primer año después de la misma se conoce como perimenopausia. La posmenopausia se define como el periodo que transcurre desde un año a partir de la fecha de última menstruación, sin importar si la menopausia fue inducida o espontánea. Debido al incremento de la esperanza de vida en la mujer mexicana, mayor número de ellas alcanzan la edad promedio de la menopausia (45-59 años y pasan una parte significativa de su vida en la posmenopausia. Se ha observado que los trastornos psiquiátricos son más frecuentes en mujeres que en hombres, y que la perimenopausia es una etapa en la cual se incrementan los síntomas psicológicos, así como el riesgo de sufrir depresión mayor y trastornos de ansiedad. Se debe diferenciar cuando la ansiedad es un síntoma normal ante determinadas situaciones cotidianas de estrés y cuando comienza a tener una presentación irracional por un estímulo ausente, por una intensidad excesiva con relación al estímulo, o cuando la duración es prolongada y presenta recidivas sin motivo, ocasionando grave disfuncionalidad en el paciente. En esta revisión presentamos datos acerca de los síntomas de ansiedad durante la transición a la menopausia y hacemos alusión al trastorno de ansiedad generalizada y trastorno de pánico, ya que se ha observado una mayor prevalencia de estas patologías durante la transición a la menopausia, probablemente debido a los cambios hormonales que se viven durante esta etapa.

Algunos autores, con el objeto de solucionar este problema, han propuesto una serie de criterios para el correcto diagnóstico del SPM, criterios que hacen referencia a síntomas tanto emocionales como comportamentales relacionados con la fase premenstrual del ciclo ovárico y cuya severidad interfiere significativamente en la vida cotidiana de las mujeres que los padecen No obstante, por una parte, algunos autores han señalado que dichos criterios diagnósticos se refieren a una manifestación ideal del trastorno y, por otra, numerosos estudios han demostrado que el patrón general de ansiedad constituye uno de los principales factores implicados en el padecimiento del SPM. En el presente trabajo, realizado con una muestra de 133 mujeres se analiza la posible relación entre el patrón general de ansiedad así como de las respuestas emocionales manifestadas en las diferentes fases del ciclo menstrual y los criterios diagnósticos del SPM.

    As part of the overall exam validation process, the Joint Commission on National Dental Examinations periodically reviews and validates the pass/fail standard for the National Board Dental Examination (NBDE), Parts I and II. The most recent standard-setting activities for NBDE Part II used the Objective Standard Setting method. This report describes the process used to set the pass/fail standard for the 2009 exam. The failure rate on the NBDE Part II increased from 5.3 percent in 2008 to 13.7 percent in 2009 and then decreased to 10 percent in 2010. This article describes the Objective Standard Setting method and presents the estimated probabilities of classification errors based on the beta binomial mathematical model. The results show that the probability of correct classifications of candidate performance is very high (0.97) and that probabilities of false negative and false positive errors are very small (.03 and <0.001, respectively). The low probability of classification errors supports the conclusion that the pass/fail score on the NBDE Part II is a valid guide for making decisions about candidates for dental licensure.

    Full Text Available En la actualidad existen un gran número de modelos teóricos que defienden la importancia de la valoración cognitiva en el inicio y mantenimiento de la respuesta de ansiedad. La investigación acerca de los procesos cognitivos que subyacen a la respuesta de ansiedad ha puesto de manifiesto de manera bastante sólida cómo los sujetos ansiosos en comparación con sujetos normales muestran una tendencia a atender de manera selectiva y a interpretar de un modo catastrofista información congruente con su estado emocional. Sin embargo, existiría un tercer sesgo para el cual los datos de las distintas investigaciones han arrojado resultados difusos en los distintos trastornos y tareas experimentales. Nos referimos al sesgo de memoria, que puede definirse como la tendencia a recordar preferentemente estimulación negativa presentada previamente en comparación con estimulación neutra. Se presenta un trabajo de revisión teórica sistemática que tiene como objetivo fundamental determinar la existencia del sesgo de memoria a lo largo de los diferentes trastornos de ansiedad y de las diferentes tareas experimentales utilizadas en la evaluación de dicho sesgo.

    Experimental Program: assembly of an experiment as Fermilab E-531 to measure decay lifetimes, with tagged emulsion of charmed particles produced by high energy neutrinos was finished, and data taking now is in progress. An experiment to measure prompt neutrino production at Fermilab, E-613, was approved and detailed design of it is continuing. Search for parity violation in scattering of polarized protons, an experiment E-446-ZGS at ANL, was performed with the sensitivity of 10 -6 for detection of that process and yielded null results. Another run with improved sensitivity of 10 -7 is in preparation. Data analysis of the neutrino experiment E-310 at Fermilab will continue. Trimuon events, a new discovery, were identified in those data. Analysis of data on meson production from experiments performed at the ZGS--ANL, E-397, E-420 and E-428, with charged and neutral spectrometer will continue. A new relatively broad resonance (T approx. 70 MeV) with quantum numbers IJ/sup P/ = 00 -1 was discovered in the data from E-397. Analysis of beta decay of polarized Σ - hyperons is in progress. Participation in the design of the experimental areas for the Isabelle colliding proton beam accelerator will continue. Theoretical Program: topics of current interest in particle theory which will be investigated in the coming year are: the instanton-anti-instanton QCD gauge fields, discrete symmetries which may determine quark masses in the SU(2) x U(1) model, calculation of charmed meson production in e + e - collisions and formation of gluon jets, Higgs boson production in pp collisions, calculation of Higgs boson mass in terms of vector boson mass, study of Lagrangians with gauge and Higgs scalar fields, investigation of Faddeev--Popov determinants as related to quantum chromodynamics, a study of quantum flavor dynamics and anomalies in the axial vector Ward identity and a study of super symmetry as a part of a realistic model of leptonic interactions

    The ideal dermal filler should offer long-lasting aesthetic improvement with a minimal side-effect profile. It should be biocompatible and stable within the injection site, with the risk of only transient undesirable effects from injection alone. However, all dermal fillers can induce serious and potentially long-lasting adverse effects. In Part II of this paper, we review the most common adverse effects related to dermal filler use.

    2017-12-01

    This is part II of a two-part series examining the impacts of aerosol particles on weather forecasts. In this study, the aerosol indirect effects on weather forecasts are explored by examining the temperature and moisture analysis associated with assimilating dust contaminated hyperspectral infrared radiances. The dust induced temperature and moisture biases are quantified for different aerosol vertical distribution and loading scenarios. The overall impacts of dust contamination on temperature and moisture forecasts are quantified over the west coast of Africa, with the assistance of aerosol retrievals from AERONET, MPL, and CALIOP. At last, methods for improving hyperspectral infrared data assimilation in dust contaminated regions are proposed.

    2016-01-01

    The number and capability of explosives detection and analysis methods have increased dramatically since publication of the Analytical and Bioanalytical Chemistry special issue devoted to Explosives Analysis [Moore DS, Goodpaster JV, Anal Bioanal Chem 395:245-246, 2009]. Here we review and critically evaluate the latest (the past five years) important advances in explosives detection, with details of the improvements over previous methods, and suggest possible avenues towards further advances in, e.g., stand-off distance, detection limit, selectivity, and penetration through camouflage or packaging. The review consists of two parts. Part I discussed methods based on animals, chemicals (including colorimetry, molecularly imprinted polymers, electrochemistry, and immunochemistry), ions (both ion-mobility spectrometry and mass spectrometry), and mechanical devices. This part, Part II, will review methods based on photons, from very energetic photons including X-rays and gamma rays down to the terahertz range, and neutrons.

  17. Alchemical poetry in medieval and early modern Europe: a preliminary survey and synthesis. Part II - Synthesis.

    Science.gov (United States)

    Kahn, Didier

    2011-03-01

    This article provides a preliminary description of medieval and early modern alchemical poetry composed in Latin and in the principal vernacular languages of western Europe. It aims to distinguish the various genres in which this poetry flourished, and to identify the most representative aspects of each cultural epoch by considering the medieval and early modern periods in turn. Such a distinction (always somewhat artificial) between two broad historical periods may be justified by the appearance of new cultural phenomena that profoundly modified the character of early modern alchemical poetry: the ever-increasing importance of the prisca theologia, the alchemical interpretation of ancient mythology, and the rise of neo-Latin humanist poetry. Although early modern alchemy was marked by the appearance of new doctrines (notably the alchemical spiritus mundi and Paracelsianism), alchemical poetry was only superficially modified by criteria of a scientific nature, which therefore appear to be of lesser importance. This study falls into two parts. Part I provides a descriptive survey of extant poetry, and in Part II the results of the survey are analysed in order to highlight such distinctive features as the function of alchemical poetry, the influence of the book market on its evolution, its doctrinal content, and the question of whether any theory of alchemical poetry ever emerged. Part II is accompanied by an index of the authors and works cited in both parts.

    2014-11-01

    The OSHA ergonomics standard issued in 2000 was repealed within four months through a Congressional resolution that limits future ergonomics rulemaking. This section continues the conversation initiated in Part I, documenting a legacy of struggle for an ergonomics standard through the voices of eight labor, academic, and government key informants. Part I summarized important components of the standard; described the convergence of labor activism, research, and government action that laid the foundation for a standard; and highlighted the debates that characterized the rulemaking process. Part II explores the anti-regulatory political landscape of the 1990s, as well as the key opponents, power dynamics, and legal maneuvers that led to repeal of the standard. This section also describes the impact of the ergonomics struggle beyond the standard itself and ends with a discussion of creative state-level policy initiatives and coalition approaches to prevent work-related musculoskeletal disorders (WMSDs) in today's sociopolitical context.

  10. PIC Simulations in Low Energy Part of PIP-II Proton Linac

    Energy Technology Data Exchange (ETDEWEB)

    Romanov, Gennady

    2014-07-01

    The front end of PIP-II linac is composed of a 30 keV ion source, low energy beam transport line (LEBT), 2.1 MeV radio frequency quadrupole (RFQ), and medium energy beam transport line (MEBT). This configuration is currently being assembled at Fermilab to support a complete systems test. The front end represents the primary technical risk with PIP-II, and so this step will validate the concept and demonstrate that the hardware can meet the specified requirements. SC accelerating cavities right after MEBT require high quality and well defined beam after RFQ to avoid excessive particle losses. In this paper we will present recent progress of beam dynamic study, using CST PIC simulation code, to investigate partial neutralization effect in LEBT, halo and tail formation in RFQ, total emittance growth and beam losses along low energy part of the linac.

  13. Zn(II, Mn(II and Sr(II Behavior in a Natural Carbonate Reservoir System. Part II: Impact of Geological CO2 Storage Conditions

    Directory of Open Access Journals (Sweden)

    Auffray B.

    2016-07-01

    Full Text Available Some key points still prevent the full development of geological carbon sequestration in underground formations, especially concerning the assessment of the integrity of such storage. Indeed, the consequences of gas injection on chemistry and petrophysical properties are still much discussed in the scientific community, and are still not well known at either laboratory or field scale. In this article, the results of an experimental study about the mobilization of Trace Elements (TE during CO2 injection in a reservoir are presented. The experimental conditions range from typical storage formation conditions (90 bar, supercritical CO2 to shallower conditions (60 and 30 bar, CO2 as gas phase, and consider the dissolution of the two carbonates, coupled with the sorption of an initial concentration of 10−5 M of Zn(II, and the consequent release in solution of Mn(II and Sr(II. The investigation goes beyond the sole behavior of TE in the storage conditions: it presents the specific behavior of each element with respect to the pressure and the natural carbonate considered, showing that different equilibrium concentrations are to be expected if a fluid with a given concentration of TE leaks to an upper formation. Even though sorption is evidenced, it does not balance the amount of TE released by the dissolution process. The increase in porosity is clearly evidenced as a linear function of the CO2 pressure imposed for the St-Emilion carbonate. For the Lavoux carbonate, this trend is not confirmed by the 90 bar experiment. A preferential dissolution of the bigger family of pores from the preexisting porosity is observed in one of the samples (Lavoux carbonate while the second one (St-Emilion carbonate presents a newly-formed family of pores. Both reacted samples evidence that the pore network evolves toward a tubular network type.

In Part II, we consider the computational complexity of ORPs arising in genetic algorithms for problems on permutations: the Travelling Salesman Problem, the Shortest Hamilton Path Problem and the Makespan Minimization on Single Machine and some other related problems. The analysis indicates that the corresponding ORPs are NP-hard, but solvable by faster algorithms, compared to the problems they are derived from.

  17. Social class, political power, and the state: their implications in medicine--parts I and II.

    Science.gov (United States)

    Navarro, V

    1976-01-01

    This three part article presents an anlysis of the distribution of power and of the nature of the state in Western industrialized societies and details their implications in medicine. Part I presents a critique of contemporary theories of the Western system of power; discusses the countervailing pluralist and power elite theories, as well as those of bureaucratic and professional control; and concludes with an examination of the Marxist theories of economic determinism, structural determinism, and corporate statism. Part II presents a Marxist theory of the role, nature, and characteristics of state intervention. Part III (which will appear in the next issue of this journal) focuses on the mode of that intervention and the reasons for its growth, with an added analysis of the attributes of state intervention in the health sector, and of the dialectical relationship between its growth and the current fiscal crisis of the state. In all three parts, the focus is on Western European countries and on North America, with many examples and categories from the area of medicine.

  18. Part I: Sound color in the music of Gyorgy Kurtag, Part II: "Leopard's Path," thirteen visions for chamber ensemble

    Science.gov (United States)

    Iachimciuc, Igor

    The dissertation is in two parts, a theoretical study and a musical composition. In Part I the music of Gyorgy Kurtag is analyzed from the point of view of sound color. A brief description of what is understood by the term sound color, and various ways of achieving specific coloristic effects, are presented in the Introduction. An examination of Kurtag's approaches to the domain of sound color occupies the chapters that follow. The musical examples that are analyzed are selected from Kurtag's different compositional periods, showing a certain consistency in sound color techniques, the most important of which are already present in the String Quartet, Op. 1. The compositions selected for analysis are written for different ensembles, but regardless of the instrumentation, certain principles of the formation and organization of sound color remain the same. Rather than relying on extended instrumental techniques, Kurtag creates a large variety of sound colors using traditional means such as pitch material, register, density, rhythm, timbral combinations, dynamics, texture, spatial displacement of the instruments, and the overall musical context. Each sound color unit in Kurtag's music is a separate entity, conceived as a complete microcosm. Sound color units can either be juxtaposed as contrasting elements, forming sound color variations, or superimposed, often resulting in a Klangfarbenmelodie effect. Some of the same gestural figures (objets trouves) appear in different compositions, but with significant coloristic modifications. Thus, the principle of sound color variations is not only a strong organizational tool, but also a characteristic stylistic feature of the music of Gyorgy Kurtag.

    To meet the power density, reliability and cost requirements that will enable a widespread use of fuel cells, many research activities focus on an understanding of the thermodynamics as well as the fluid mechanical and electrochemical processes within a fuel cell. To date, a wide range of experimental diagnostics is imperative not only to help a fundamental understanding of fuel cell dynamics but also to provide benchmark-quality data for modeling research. This paper reviews various tools for diagnosing polymer electrolyte membrane (PEM) fuel cells and stacks, and attempts to incorporate the most recent technical advances in PEM fuel cell diagnosis. In Part I of the review we covered electrochemical techniques. In Part II, we review various physical/chemical methods and outline the principle, experimental implementation and data processing of each technique. Capabilities and weaknesses of these techniques are also discussed. (author)

    Moral distress remains a pervasive and, at times, contested concept in nursing and other health care disciplines. Ethical climate, the conditions and practices in which ethical situations are identified, discussed, and decided, has been shown to exacerbate or ameliorate perceptions of moral distress. The purpose of this mixed-methods study was to explore perceptions of moral distress, moral residue, and ethical climate among registered nurses working in an academic medical center. Two versions of the Moral Distress Scale in addition to the Hospital Ethical Climate Survey were used, and participants were invited to respond to 2 open-ended questions. Part I reported the findings among nurses working in adult acute and critical care units. Part II presents the results from nurses working in pediatric/neonatal units. Significant differences in findings between the 2 groups are discussed. Subsequent interventions developed are also presented.

    2010-10-01

    As discussed in Part I, the type of curing light and curing mode impact the polymerization kinetics of resin-based composite (RBC) materials. Major changes in light-curing units and curing modes have occurred. The type of curing light and mode employed affects the polymerization shrinkage and associated stresses, microhardness, depth of cure, degree of conversion, and color change of RBCs. These factors also may influence the microleakage in an RBC restoration. Apart from the type of unit and mode used, the polymerization of RBCs is also affected by how a light-curing unit is used and handled, as well as the aspects associated with RBCs and the environment. Part II discusses the various clinical issues that should be considered while curing RBC restorations in order to achieve the best possible outcome.

    2014-04-01

    In a series of two contributions, decisive business-related aspects of the current process status to transfer research results on diffractive optical elements (DOEs) into commercial solutions are discussed. In part I, the focus was on the patent landscape. Here, in part II, market estimations concerning DOEs for selected applications are presented, comprising classical spectroscopic gratings, security features on banknotes, DOEs for high-end applications, e.g., for the semiconductor manufacturing market and diffractive intra-ocular lenses. The derived market sizes are referred to the optical elements, itself, rather than to the enabled instruments. The estimated market volumes are mainly addressed to scientifically and technologically oriented optical engineers to serve as a rough classification of the commercial dimensions of DOEs in the different market segments and do not claim to be exhaustive.

    Cancer stands as second most common cause of disease-related deaths in humans. Resistance of cancer to chemotherapy remains challenging to both scientists and physicians. Medicinal plants are known to contribute significantly to a large population of Africa, which is to a very large extent linked to folkloric claims which is part of their livelihood. In this review paper, the potential of naturally occurring anti-cancer agents from African flora has been explored, with suggested modes of action, where such data is available. Literature search revealed plant-derived compounds from African flora showing anti-cancer and/or cytotoxic activities, which have been tested in vitro and in vivo. This corresponds to 400 compounds (from mildly active to very active) covering various compound classes. However, in this part II, we only discussed the three major compound classes which are: flavonoids, alkaloids and terpenoids.

    2017-11-01

    Full Text Available The article is devoted to the study of grotesque forms in Jonathan Swift's novel "Gulliver’s Travels" based on the text of part II of the novel "A Voyage to Brobdingnag". On the basis of the selected actual material, displays of the grotesque elements in the semantic field of the work’s text are traced. The grotesque world of the novel is the author's model of mankind, in which J. Swift presents his view not only on the state of the modern system of England, but also on the nature of man in general, reveals the peculiarities of the psychology of human nature, especially human socialization. In part II, the author continues to develop a complex and contradictory picture of human existence in front of the reader, the world of giants appears as an ambivalent system in which the features of an ideal society and ideal ruler, in author’s opinion, with the ugly face of man and society, are marvelously combined.

    In part I general aspects of the renormalization of a spontaneously broken gauge theory have been introduced. Here, in part II, two-loop renormalization is introduced and discussed within the context of the minimal Standard Model. Therefore, this paper deals with the transition between bare parameters and fields to renormalized ones. The full list of one- and two-loop counterterms is shown and it is proven that, by a suitable extension of the formalism already introduced at the one-loop level, two-point functions suffice in renormalizing the model. The problem of overlapping ultraviolet divergencies is analyzed and it is shown that all counterterms are local and of polynomial nature. The original program of 't Hooft and Veltman is at work. Finite parts are written in a way that allows for a fast and reliable numerical integration with all collinear logarithms extracted analytically. Finite renormalization, the transition between renormalized parameters and physical (pseudo-)observables, are discussed in part III where numerical results, e.g. for the complex poles of the unstable gauge bosons, are shown. An attempt is made to define the running of the electromagnetic coupling constant at the two-loop level. (orig.)

    2002-01-01

    The practice of pathology is currently undergoing significant change, in large part due to advances in the analysis of DNA, RNA, and proteins in tissues. These advances have permitted improved biologic insights into many developmental, inflammatory, metabolic, infectious, and neoplastic diseases. Moreover, molecular analysis has also led to improvements in the accuracy of disease diagnosis and classification. It is likely that, in the future, these methods will increasingly enter into the day-to-day diagnosis and management of patients. The pathologist will continue to play a fundamental role in diagnosis and will likely be in a pivotal position to guide the implementation and interpretation of these tests as they move from the research laboratory into diagnostic pathology. The purpose of this 2-part series is to provide an overview of the principles and applications of current molecular biologic and immunologic tests. In Part I, the biologic fundamentals of DNA, RNA, and proteins and methods that are currently available or likely to become available to the pathologist in the next several years for their isolation and analysis in tissue biopsies were discussed. In Part II, advances in immunohistochemistry and immunofluorescence methods and their application to modern diagnostic pathology are reviewed.

  13. Seismic risk analysis for General Electric Plutonium Facility, Pleasanton, California. Final report, part II

    International Nuclear Information System (INIS)

    1980-01-01

    This report is the second of a two part study addressing the seismic risk or hazard of the special nuclear materials (SNM) facility of the General Electric Vallecitos Nuclear Center at Pleasanton, California. The Part I companion to this report, dated July 31, 1978, presented the seismic hazard at the site that resulted from exposure to earthquakes on the Calaveras, Hayward, San Andreas and, additionally, from smaller unassociated earthquakes that could not be attributed to these specific faults. However, while this study was in progress, certain additional geologic information became available that could be interpreted in terms of the existance of a nearby fault. Although substantial geologic investigations were subsequently deployed, the existance of this postulated fault, called the Verona Fault, remained very controversial. The purpose of the Part II study was to assume the existance of such a capable fault and, under this assumption, to examine the loads that the fault could impose on the SNM facility. This report first reviews the geologic setting with a focus on specifying sufficient geologic parameters to characterize the postulated fault. The report next presents the methodology used to calculate the vibratory ground motion hazard. Because of the complexity of the fault geometry, a slightly different methodology is used here compared to the Part I report. This section ends with the results of the calculation applied to the SNM facility. Finally, the report presents the methodology and results of the rupture hazard calculation

    2004-01-01

    Parents caring for a child with a chronic condition must attend to a myriad of day-to-day management responsibilities and activities. Part I of this two-part series (in the previous issue of Pediatric Nursing) reviewed both the adult and pediatric family caregiving literature within the context of four major categories of responsibilities: (a) managing the illness, which includes hands-on care, monitoring and interpreting signs and symptoms, as well as problem-solving and decision-making processes; (b) identifying, accessing, and coordinating resources, which involves assessing and negotiating community resources including health care providers; (c) maintaining the family unit, including balancing illness and family demands while at the same time attempting to meet the health and developmental needs of each family member; and (d) maintaining self, including physical, emotional, and spiritual health.. Part II presents a multifaceted list of parent caregiving management responsibilities and associated activities, and discusses nursing implications. The list was developed to facilitate "caregiving" dialogue between health care providers and families of children with chronic conditions. It is hoped that through such partnerships creative ways of educating, preparing, and supporting caregivers will be generated.

    Since a 1997 review by Karageorghis and Terry, which highlighted the state of knowledge and methodological weaknesses, the number of studies investigating musical reactivity in relation to exercise has swelled considerably. In this two-part review paper, the development of conceptual approaches and mechanisms underlying the effects of music are explicated (Part I), followed by a critical review and synthesis of empirical work (spread over Parts I and II). Pre-task music has been shown to optimise arousal, facilitate task-relevant imagery and improve performance in simple motoric tasks. During repetitive, endurance-type activities, self-selected, motivational and stimulative music has been shown to enhance affect, reduce ratings of perceived exertion, improve energy efficiency and lead to increased work output. There is evidence to suggest that carefully selected music can promote ergogenic and psychological benefits during high-intensity exercise, although it appears to be ineffective in reducing perceptions of exertion beyond the anaerobic threshold. The effects of music appear to be at their most potent when it is used to accompany self-paced exercise or in externally valid conditions. When selected according to its motivational qualities, the positive impact of music on both psychological state and performance is magnified. Guidelines are provided for future research and exercise practitioners. PMID:22577473

  19. Noncardiac findings on cardiac CT. Part II: spectrum of imaging findings.

    2012-02-01

    Cardiac computed tomography (CT) has evolved into an effective imaging technique for the evaluation of coronary artery disease in selected patients. Two distinct advantages over other noninvasive cardiac imaging methods include its ability to directly evaluate the coronary arteries and to provide a unique opportunity to evaluate for alternative diagnoses by assessing the extracardiac structures, such as the lungs and mediastinum, particularly in patients presenting with the chief symptom of acute chest pain. Some centers reconstruct a small field of view (FOV) cropped around the heart but a full FOV (from skin to skin in the area irradiated) is obtainable in the raw data of every scan so that clinically relevant noncardiac findings are identifiable. Debate in the scientific community has centered on the necessity for this large FOV. A review of noncardiac structures provides the opportunity to make alternative diagnoses that may account for the patient\\'s presentation or to detect important but clinically silent problems such as lung cancer. Critics argue that the yield of biopsy-proven cancers is low and that the follow-up of incidental noncardiac findings is expensive, resulting in increased radiation exposure and possibly unnecessary further testing. In this 2-part review we outline the issues surrounding the concept of the noncardiac read, looking for noncardiac findings on cardiac CT. Part I focused on the pros and cons for and against the practice of identifying noncardiac findings on cardiac CT. Part II illustrates the imaging spectrum of cardiac CT appearances of benign and malignant noncardiac pathology.

  20. From Constraints to Resolution Rules Part II : chains, braids, confluence and T&E

    Science.gov (United States)

    Berthier, Denis

    In this Part II, we apply the general theory developed in Part I to a detailed analysis of the Constraint Satisfaction Problem (CSP). We show how specific types of resolution rules can be defined. In particular, we introduce the general notions of a chain and a braid. As in Part I, these notions are illustrated in detail with the Sudoku example - a problem known to be NP-complete and which is therefore typical of a broad class of hard problems. For Sudoku, we also show how far one can go in "approximating" a CSP with a resolution theory and we give an empirical statistical analysis of how the various puzzles, corresponding to different sets of entries, can be classified along a natural scale of complexity. For any CSP, we also prove the confluence property of some Resolution Theories based on braids and we show how it can be used to define different resolution strategies. Finally, we prove that, in any CSP, braids have the same solving capacity as Trial-and-Error (T&E) with no guessing and we comment this result in the Sudoku case.

    2018-01-01

    In this study, we investigated the impact of adding solutions with different potassium and sodium concentrations on dispersible clay, water retention characteristics, air permeability, and soil shrinkage behaviour using two agricultural soils from Switzerland with different clay content but similar organic carbon to clay ratio. Three different solutions (including only Na, only K, and the combination of both) were added to soil samples at three different cation ratio of soil structural stability levels, and the soil samples were incubated for one month. Our findings showed that the amount of readily dispersible clay increased with increasing Na concentrations and with increasing cation ratio of soil structural stability. The treatment with the maximum Na concentration resulted in the highest water retention and in the lowest shrinkage capacity. This was was associated with high amounts of readily dispersible clay. Air permeability generally increased during incubation due to moderate wetting and drying cycles, but the increase was negatively correlated with readily dispersible clay. Readily dispersible clay decreased with increasing K, while readily dispersible clay increased with increasing K in Iranian soil (Part I of our study). This can be attributed to the different clay mineralogy of the studied soils (muscovite in Part I and illite in Part II).

  3. Multiobjective Optimization for Fixture Locating Layout of Sheet Metal Part Using SVR and NSGA-II

    2017-01-01

    Full Text Available Fixture plays a significant role in determining the sheet metal part (SMP spatial position and restraining its excessive deformation in many manufacturing operations. However, it is still a difficult task to design and optimize SMP fixture locating layout at present because there exist multiple conflicting objectives and excessive computational cost of finite element analysis (FEA during the optimization process. To this end, a new multiobjective optimization method for SMP fixture locating layout is proposed in this paper based on the support vector regression (SVR surrogate model and the elitist nondominated sorting genetic algorithm (NSGA-II. By using ABAQUS™ Python script interface, a parametric FEA model is established. And the fixture locating layout is treated as design variables, while the overall deformation and maximum deformation of SMP under external forces are as the multiple objective functions. First, a limited number of training and testing samples are generated by combining Latin hypercube design (LHD with FEA. Second, two SVR prediction models corresponding to the multiple objectives are established by learning from the limited training samples and are integrated as the multiobjective optimization surrogate model. Third, NSGA-II is applied to determine the Pareto optimal solutions of SMP fixture locating layout. Finally, a multiobjective optimization for fixture locating layout of an aircraft fuselage skin case is conducted to illustrate and verify the proposed method.

  4. Domestic violence perpetrator programs in Europe, Part II: A systematic review of the state of evidence.

    Akoensi, Thomas D; Koehler, Johann A; Lösel, Friedrich; Humphreys, David K

    2013-10-01

    In Part II of this article, we present the results of a systematic review of European evidence on the effectiveness of domestic violence perpetrator programs. After searching through 10,446 titles, we discovered only 12 studies that evaluated the effectiveness of a perpetrator program in some systematic manner. The studies applied treatment to a total of 1,586 domestic violence perpetrators, and the sample sizes ranged from 9 to 322. Although the evaluations showed various positive effects after treatment, methodological problems relating to the evaluation designs do not allow attribution of these findings to the programs. Overall, the methodological quality of the evaluations is insufficient to derive firm conclusions and estimate an effect size. Accordingly, one cannot claim that one programmatic approach is superior to another. Evaluation of domestic violence perpetrator treatment in Europe must be improved and programs should become more tailored to the characteristics of the participants.

    Tevatron Run II is under way at Fermilab, exploring the high-energy frontier with upgraded detectors that will address some of the biggest questions in particle physics.Until CERN's LHC switches on, the Tevatron proton-antiproton collider is the world's only source of top quarks. It is the only place where we can search for supersymmetry, for the Higgs boson, and for signatures of additional dimensions of space-time. The US Department of Energy (DOE) recently convened a high-level international review committee to examine Fermilab experts' first-phase plans for the accelerator complex. Pictured here with a dipole magnet in CERN's LHC magnet test facility are the four CERN scientists who took part in the DOE's Tevatron review.

The examination of smoke chemistry has concentrated on those constituents in smoke that regulatory authorities in the USA and Canada believe to be relevant to smoking-related diseases. In this part of the study the effects of 29 casing ingredients and three humectants have been assessed at the maximum levels typically used on cigarettes by British American Tobacco. This brings the total number of ingredients assessed in Parts I and II of this study to 482. The casing ingredients were added at levels of up to 68 mg on the cigarettes. Their effects on smoke constituents were generally larger than the effects of flavouring ingredients, which were added at parts per million levels. Many of the casing ingredient mixtures either had no statistically significant effect on the level of the analytes investigated in smoke relative to a control cigarette, or they produced decreases of up to 44% in some cases. Those analytes that were increased in smoke are highlighted in this paper. The largest increases were for formaldehyde levels, up to 26 microg (73%) in one case, observed from casing mixtures containing sugar. This is most likely due to the generation of formaldehyde by pyrolysis of sugars. Occasional small increases were also observed for other analytes. However, the statistical significance of many of these increases was not present when the long-term variability of the analytical method was taken into account. The significance and possible reasons for the increases are discussed.

    The objective of Part II is to analyze the dataset of extracted hemodynamic features (Case 3 of Part I) through computational intelligence (CI) techniques for identification of potential prognostic factors for periventricular leukomalacia (PVL) occurrence in neonates with congenital heart disease. The extracted features (Case 3 dataset of Part I) were used as inputs to CI based classifiers, namely, multi-layer perceptron (MLP) and probabilistic neural network (PNN) in combination with genetic algorithms (GA) for selection of the most suitable features predicting the occurrence of PVL. The selected features were next used as inputs to a decision tree (DT) algorithm for generating easily interpretable rules of PVL prediction. Prediction performance for two CI based classifiers, MLP and PNN coupled with GA are presented for different number of selected features. The best prediction performances were achieved with 6 and 7 selected features. The prediction success was 100% in training and the best ranges of sensitivity (SN), specificity (SP) and accuracy (AC) in test were 60-73%, 74-84% and 71-74%, respectively. The identified features when used with the DT algorithm gave best SN, SP and AC in the ranges of 87-90% in training and 80-87%, 74-79% and 79-82% in test. Among the variables selected in CI, systolic and diastolic blood pressures, and pCO(2) figured prominently similar to Part I. Decision tree based rules for prediction of PVL occurrence were obtained using the CI selected features. The proposed approach combines the generalization capability of CI based feature selection approach and generation of easily interpretable classification rules of the decision tree. The combination of CI techniques with DT gave substantially better test prediction performance than using CI and DT separately.

    Full Text Available ¿Cómo responde el cerebro de una persona con ansiedad a las matemáticas? Nuestro estudio muestra que los estudiantes con mucha ansiedad hacia las matemáticas presentan un componente electroencefalográfico llamado negatividad asociada al error (NAE de mayor tamaño que aquellos con poca ansiedad. Esta diferencia emerge en errores en tareas numéricas, lo que sugiere que las personas con alta ansiedad son hipersensibles a la comisión de estos errores. Este hallazgo aporta nuevo conocimiento sobre las bases cerebrales de la ansiedad hacia las matemáticas y sugiere que esta hipersensibilidad al error numérico podría ser un factor determinante tanto en el origen como en el mantenimiento de esta ansiedad.

  11. [Education in our time: competency or aptitude? The case for medicine. Part II].

    Science.gov (United States)

    Viniegra-Velázquez, Leonardo

    Part II is focused on participatory education (PE), a distinctive way to understand and practice education in contrast to passive education. The core of PE is to develop everyone's own cognitive potentialities frequently mutilated, neglected or ignored. Epistemological and experiential basis of PE are defined: the concept of incisive and creative criticism, the idea of knowledge as each person's own construct and life experience as the main focus of reflection and cognition. The PE aims towards individuals with unprecedented cognitive and creative faculties, capable of approaching a more inclusive and hospitable world. The last part criticizes the fact that medical education has remained among the passive education paradigm. The key role of cognitive aptitudes, both methodological and practical (clinical aptitude), in the progress of medical education and practice is emphasized. As a conclusion, the knowhow of education is discussed, aiming towards a better world away from human and planetary degradation. Copyright © 2017 Hospital Infantil de México Federico Gómez.

    2009-07-01

    Since the 2003 launch of NC Health Info, the National Library of Medicine has encouraged the development of Go Local databases. A team of Go Local enthusiasts at North Dakota's only medical school library wanted to obtain NLM funding and build a resource for their rural state. Although short on staff, money, and time, the team found a way to realize a Go Local database that serves the state's residents and helps them "Discover Health Services Near You!" A team approach and collaboration with health providers and organizations worked well in this small rural state. North Dakota's Go Local project offers a low-cost model that stresses collaboration, teamwork and technology. Part I which appeared in the last issue describes the rural setting, explains how the project was conceived, and the processes necessary to begin building the database. Part II which appears in this issue details how records were created including developing the input style guide and indexing decisions, the NLM testing and review process, the maintenance and auditing process, and publicity and promotion of the project.

  13. Resistance and Elastic Stiffness of RHS "T" Joints: Part II - Combined Axial Brace and Chord Loading

    Directory of Open Access Journals (Sweden)

    R.M.M.P. de Matos

    Full Text Available Abstract This paper deals with the behaviour of welded "T" joints between RHS sections submitted to tension brace loading combined with chord axial loading. In the companion paper (part I a finite element model and a study without axial load in the chord, focusing on the joint behaviour as a function of the significant geometrical variables, were presented. In this part II paper, tension loading on the brace is incremented up to the joint failure, but is combined with different chord load levels in tension or compression, that are kept constant for each case. The same geometries and geometric variables as in the companion paper are used, and therefore the influence of these features together with the chord load level (in tension or compression on the connection's response is evaluated. The force-displacement curves from the different geometries and chord load levels are analysed and compared, with a special attention on the influence of the chord load on the joint resistance and stiffness. Finally, a comparison of the numerical results with the (Eurocode 3, 2005 and the newer (ISO 14346, 2013 provisions is presented and discussed.

  14. Adaptive Core Simulation Employing Discrete Inverse Theory - Part II: Numerical Experiments

    2005-01-01

    Use of adaptive simulation is intended to improve the fidelity and robustness of important core attribute predictions such as core power distribution, thermal margins, and core reactivity. Adaptive simulation utilizes a selected set of past and current reactor measurements of reactor observables, i.e., in-core instrumentation readings, to adapt the simulation in a meaningful way. The companion paper, ''Adaptive Core Simulation Employing Discrete Inverse Theory - Part I: Theory,'' describes in detail the theoretical background of the proposed adaptive techniques. This paper, Part II, demonstrates several computational experiments conducted to assess the fidelity and robustness of the proposed techniques. The intent is to check the ability of the adapted core simulator model to predict future core observables that are not included in the adaption or core observables that are recorded at core conditions that differ from those at which adaption is completed. Also, this paper demonstrates successful utilization of an efficient sensitivity analysis approach to calculate the sensitivity information required to perform the adaption for millions of input core parameters. Finally, this paper illustrates a useful application for adaptive simulation - reducing the inconsistencies between two different core simulator code systems, where the multitudes of input data to one code are adjusted to enhance the agreement between both codes for important core attributes, i.e., core reactivity and power distribution. Also demonstrated is the robustness of such an application

    Wakefield, J C

    1997-07-01

    In Part I (Wakefield, 1997, Behaviour Research and Therapy, 35, 633-649) of this two-article series, I used the harmful dysfunction analysis of the concept of disorder (Wakefield, 1992a, American Psychologist, 47, 373-388) to 'diagnose' a problem with DSM-IV. I argued that DSM-IV diagnostic criteria often violate the 'dysfunction' requirement by invalidity classifying harms not caused by dysfunctions as disorders. In Part II, I examine Eysenck's (Eysenck, 1986, Contemporary directions in psychopathology: Toward the DSM-IV) argument that DSM commits a 'categorical fallacy' and should be replaced by dimensional diagnoses based on Eysenckian personality traits. I argue that Eysenck's proposed diagnostic criteria violate the 'harm' requirement by invalidly classifying symptomless conditions as disorders. Eysenck commits an 'essentialist fallacy'; he misconstrues 'disorder' as an essentialist theoretical concept when in fact it is a hybrid theoretical-practical or 'cause-effect' concept. He thus ignores the harmful effects essential to disorder that are captured in DSM's symptom-based categories.

    Qualitative methods are increasingly being used in emergency care research. Rigorous qualitative methods can play a critical role in advancing the emergency care research agenda by allowing investigators to generate hypotheses, gain an in-depth understanding of health problems or specific populations, create expert consensus, and develop new intervention and dissemination strategies. In Part I of this two-article series, we provided an introduction to general principles of applied qualitative health research and examples of its common use in emergency care research, describing study designs and data collection methods most relevant to our field (observation, individual interviews, and focus groups). Here in Part II of this series, we outline the specific steps necessary to conduct a valid and reliable qualitative research project, with a focus on interview-based studies. These elements include building the research team, preparing data collection guides, defining and obtaining an adequate sample, collecting and organizing qualitative data, and coding and analyzing the data. We also discuss potential ethical considerations unique to qualitative research as it relates to emergency care research. PMID:26284572

  18. Tobacco control and gender in south-east Asia. Part II: Singapore and Vietnam.

    Morrow, Martha; Barraclough, Simon

    2003-12-01

    In the World Health Organization's Western Pacific Region, being born male is the single greatest risk marker for tobacco use. While the literature demonstrates that risks associated with tobacco use may vary according to sex, gender refers to the socially determined roles and responsibilities of men and women, who initiate, continue and quit using tobacco for complex and often different reasons. Cigarette advertising frequently appeals to gender roles. Yet tobacco control policy tends to be gender-blind. Using a broad, gender-sensitivity framework, this contradiction is explored in four Western Pacific countries. Part I of the study presented the rationale, methodology and design of the study, discussed issues surrounding gender and tobacco, and analysed developments in Malaysia and the Philippines (see the previous issue of this journal). Part II deals with Singapore and Vietnam. In all four countries gender was salient for the initiation and maintenance of smoking. Yet, with a few exceptions, gender was largely unrecognized in control policy. Suggestions for overcoming this weakness in order to enhance tobacco control are made.

    Microfungi were collected in southern Mexico in the vicinity of Puerto Escondido, Oaxaca in 2007. In 2006, samples were gathered from Acacia myrmecophytes [(Remarkable microfungi from Oaxaca of Acacia species) Part I]. In the present investigation [Part II], we collected microfungi from different parts of a variety of wild and cultivated higher plants belonging to the families Anacardiaceae, Caricaceae, Fabaceae, Moraceae, and Nyctaginacae. The microfungi found here live as parasites or saprophytes. Interestingly, the species Colletotrichum lindemuthianum (Sacc. and Magn.) Briosi and Cavara has repeatedly been used to cause fungal infections of Phaseolus lunatus leaves in laboratory experiments. We could now find the same fungus as parasite on the same host plants under field conditions showing that results obtained in the laboratory are also relevant in nature. Most of the fungal species collected belong to the classes Ascomycotina, Basidiomycotina and Deuteromycotina. Until now, some of the microfungi identified in this study have been rarely observed before or have been reported for the first time in Mexico, for example: Pestalotia acaciae Thüm. on Acacia collinsii Safford; Corynespora cassiicola (Berk. and M.A. Curtis) C.T. Wei on Carica papaya L.; Botryosphaeria ribis Grossenb. and Duggar and Cercosporella leucaenae (Raghu Ram and Mallaiah) U. Braun (new for Mexico) and Camptomeris leucaenae (F. Stevens and Dalbey) Syd. (new for Mexico) on Leucaena leucocephala (Lam.) de Wit.; Oidium clitoriae Narayanas. and K. Ramakr. and Phakopsora cf. pachyrhizi Sydow and Sydow (new for Mexico) on Clitoria ternatea L.; Botryosphaeria obtusa (Schw.) Shoemaker on Prosopis juliflora (Sw.)

  2. On the Processing of Spalling Experiments. Part II: Identification of Concrete Fracture Energy in Dynamic Tension

    2017-12-01

    This paper presents a second part of the study aimed at investigating the fracture behavior of concrete under high strain rate tensile loading. The experimental method together with the identified stress-strain response of three tests conducted on ordinary concrete have been presented in the paper entitled Part I (Forquin and Lukić in Journal of Dynamic Behavior of Materials, 2017. https://doi.org/10.1007/s40870-017-0135-1). In the present paper, Part II, the investigation is extended towards directly determining the specific fracture energy of each observed fracture zone by visualizing the dynamic cracking process with a temporal resolution of 1 µs. Having access to temporal displacement fields of the sample surface, it is possible to identify the fracture opening displacement (FOD) and the fracture opening velocity of any principle (open) and secondary (closed) fracture at each measurement instance, that may or may not lead to complete physical failure of the sample. Finally, the local Stress-FOD curves were obtained for each observed fracture zone, opposed to previous works where indirect measurements were used. The obtained results indicated a much lower specific fracture energy compared to the results often found in the literature. Furthermore, numerical simulations were performed with a damage law to evaluate the validity of the proposed experimental data processing and compare it to the most often used one in the previous works. The results showed that the present method can reliably predict the specific fracture energy needed to open one macro-fracture and suggested that indirect measurement techniques can lead to an overestimate of specific fracture energy due to the stringent assumption of linear elasticity up-to the peak and the inability of having access to the real post-peak change of axial stress.

    Despite the availability of more than 15 new "antiepileptic drugs", the proportion of patients with pharmacoresistant epilepsy has remained constant at about 20-30%. Furthermore, no disease-modifying treatments shown to prevent the development of epilepsy following an initial precipitating brain injury or to reverse established epilepsy have been identified to date. This is likely in part due to the polyetiologic nature of epilepsy, which in turn requires personalized medicine approaches. Recent advances in imaging, pathology, genetics, and epigenetics have led to new pathophysiological concepts and the identification of monogenic causes of epilepsy. In the context of these advances, the First International Symposium on Personalized Translational Epilepsy Research (1st ISymPTER) was held in Frankfurt on September 8, 2016, to discuss novel approaches and future perspectives for personalized translational research. These included new developments and ideas in a range of experimental and clinical areas such as deep phenotyping, quantitative brain imaging, EEG/MEG-based analysis of network dysfunction, tissue-based translational studies, innate immunity mechanisms, microRNA as treatment targets, functional characterization of genetic variants in human cell models and rodent organotypic slice cultures, personalized treatment approaches for monogenic epilepsies, blood-brain barrier dysfunction, therapeutic focal tissue modification, computational modeling for target and biomarker identification, and cost analysis in (monogenic) disease and its treatment. This report on the meeting proceedings is aimed at stimulating much needed investments of time and resources in personalized translational epilepsy research. This Part II includes the experimental and translational approaches and a discussion of the future perspectives, while the diagnostic methods, EEG network analysis, biomarkers, and personalized treatment approaches were addressed in Part I [1].

    Highlights: • A comprehensive model was developed to optimize the integrated TEG-heat exchanger. • The developed model was validated with the experimental data. • The effect of using different interface materials on the output power was assessed. • The influence of TEG arrangement on the power production was investigated. • Optimized geometrical parameters and proper interface materials were suggested. - Abstract: In Part I of this study, the performance of an experimental integrated thermoelectric generator (TEG)-heat exchanger was presented. In the current study, Part II, the obtained experimental results are compared with those predicted by a finite element (FE) model. In the simulation of the integrated TEG-heat exchanger, the thermal contact resistance between the TEG and the heat exchanger is modeled assuming either an ideal thermal contact or using a combined Cooper–Mikic–Yovanovich (CMY) and parallel plate gap formulation, which takes into account the contact pressure, roughness and hardness of the interface surfaces as well as the air gap thermal resistance at the interface. The combined CMY and parallel plate gap model is then further developed to simulate the thermal contact resistance for the case of an interface material. The numerical results show good agreement with the experimental data with an average deviation of 17% for the case without interface material and 12% in the case of including additional material at the interfaces. The model is then employed to evaluate the power production of the integrated system using different interface materials, including graphite, aluminum (Al), tin (Sn) and lead (Pb) in a form of thin foils. The numerical results show that lead foil at the interface has the best performance, with an improvement in power production of 34% compared to graphite foil. Finally, the model predicts that for a certain flow rate, increasing the parallel TEG channels for the integrated systems with 4, 8, and 12 TEGs

    Clinical results have demonstrated that dark purple port wine stain (PWS) birthmarks respond favorably to laser induced photothermolysis after the first three to five treatments. Nevertheless, complete blanching is rarely achieved and the lesions stabilize at a red-pink color. In a feasibility study (Part I), we showed that local hypobaric pressure on PWS human skin prior to laser irradiation induced significant lesion blanching. The objective of the present study (Part II) is to investigate the effects of hypobaric pressures on the efficiency of cryogen spray cooling (CSC), a technique that assists laser therapy of PWS and other dermatoses. Experiments were carried out within a suction cup and vacuum chamber to study the effect of hypobaric pressure on the: (1) interaction of cryogen sprays with human skin; (2) spray atomization; and (3) thermal response of a model skin phantom. A high-speed camera was used to acquire digital images of spray impingement on in vivo human skin and spray cones generated at different hypobaric pressures. Subsequently, liquid cryogen was sprayed onto a skin phantom at atmospheric and 17, 34, 51, and 68 kPa (5, 10, 15, and 20 in Hg) hypobaric pressures. A fast-response temperature sensor measured sub-surface phantom temperature as a function of time. Measurements were used to solve an inverse heat conduction problem to calculate surface temperatures, heat flux, and overall heat extraction at the skin phantom surface. Under hypobaric pressures, cryogen spurts did not produce skin indentation and only minimal frost formation. Sprays also showed shorter jet lengths and better atomization. Lower minimum surface temperatures and higher overall heat extraction from skin phantoms were reached. The combined effects of hypobaric pressure result in more efficient cryogen evaporation that enhances heat extraction and, therefore, improves the epidermal protection provided by CSC.

    Long-duration space flight and eventual colonization of our solar system will require successful control of reproductive function and a thorough understanding of factors unique to space flight and their impact on gynecologic and obstetric parameters. Part II of this paper examines the specific environmental factors associated with space flight and the implications for human reproduction. Space environmental hazards discussed include radiation, alteration in atmospheric pressure and breathing gas partial pressures, prolonged toxicological exposure, and microgravity. The effects of countermeasures necessary to reduce cardiovascular deconditioning, calcium loss, muscle wasting, and neurovestibular problems are also considered. In addition, the impact of microgravity on male fertility and gamete quality is explored. Due to current constraints, human pregnancy is now contraindicated for space flight. However, a program to explore effective countermeasures to current constraints and develop the required health care delivery capability for extended-duration space flight is suggested. A program of Earth- and space-based research to provide further answers to reproductive questions is suggested.

    The State of the Science in Spirituality and Palliative Care was convened to address the current landscape of research at the intersection of spirituality and palliative care and to identify critical next steps to advance this field of inquiry. Part II of the SOS-SPC report addresses the state of extant research and identifies critical research priorities pertaining to the following questions: 1) How do we assess spirituality? 2) How do we intervene on spirituality in palliative care? And 3) How do we train health professionals to address spirituality in palliative care? Findings from this report point to the need for screening and assessment tools that are rigorously developed, clinically relevant, and adapted to a diversity of clinical and cultural settings. Chaplaincy research is needed to form professional spiritual care provision in a variety of settings, and outcomes assessed to ascertain impact on key patient, family, and clinical staff outcomes. Intervention research requires rigorous conceptualization and assessments. Intervention development must be attentive to clinical feasibility, incorporate perspectives and needs of patients, families, and clinicians, and be targeted to diverse populations with spiritual needs. Finally, spiritual care competencies for various clinical care team members should be refined. Reflecting those competencies, training curricula and evaluation tools should be developed, and the impact of education on patient, family, and clinician outcomes should be systematically assessed.

    The Environmentally Responsible Aviation Project aimed to develop aircraft technologies enabling significant fuel burn and community noise reductions. Small incremental changes to the conventional metallic alloy-based 'tube and wing' configuration were not sufficient to achieve the desired metrics. One airframe concept identified by the project as having the potential to dramatically improve aircraft performance was a composite-based hybrid wing body configuration. Such a concept, however, presented inherent challenges stemming from, among other factors, the necessity to transfer wing loads through the entire center fuselage section which accommodates a pressurized cabin confined by flat or nearly flat panels. This paper discusses a finite element analysis and the testing of a large-scale hybrid wing body center section structure developed and constructed to demonstrate that the Pultruded Rod Stitched Efficient Unitized Structure concept can meet these challenging demands of the next generation airframes. Part II of the paper considers the final test to failure of the test article in the presence of an intentionally inflicted severe discrete source damage under the wing up-bending loading condition. Finite element analysis results are compared with measurements acquired during the test and demonstrate that the hybrid wing body test article was able to redistribute and support the required design loads in a severely damaged condition.

    Full Text Available Diversas investigaciones coinciden en señalar que la elevada ansiedad frente a los exámenes está asociada a la baja habilidad para el estudio y al uso de estrategias superficiales de procesamiento de la información, existendo influencias recíprocas entre dichas variables. De acuerdo a esta perspectiva, se evaluó el uso de estrategias de aprendizaje en 816 estudiantes universitarios con elevada, media o baja ansiedad frente a los exámenes. Adicionalmente, se analizaron las relaciones entre las cuatro dimensiones de la ansiedad y las estrategias de aprendizaje. Los estudiantes con elevada ansiedad utilizaron más frecuentemente estrategias de repetición y búqueda de ayuda académica y los de baja ansiedad, estrategias de estudio reflexivo. La falta de confianza correlacionó negativamente con estrategias de estudio reflexivo, repetición, búsqueda de ayuda académica y regulación del tiempo y esfuerzo. En sentido opuesto, la preocupación se asoció positivamente con tres de estas estrategias.

    This study forms part II of two papers describing ECHAM6-FESOM, a newly established global climate model with a unique multi-resolution sea ice-ocean component. While part I deals with the model description and the mean climate state, here we examine the internal climate variability of the model under constant present-day (1990) conditions. We (1) assess the internal variations in the model in terms of objective variability performance indices, (2) analyze variations in global mean surface temperature and put them in context to variations in the observed record, with particular emphasis on the recent warming slowdown, (3) analyze and validate the most common atmospheric and oceanic variability patterns, (4) diagnose the potential predictability of various climate indices, and (5) put the multi-resolution approach to the test by comparing two setups that differ only in oceanic resolution in the equatorial belt, where one ocean mesh keeps the coarse 1° resolution applied in the adjacent open-ocean regions and the other mesh is gradually refined to 0.25°. Objective variability performance indices show that, in the considered setups, ECHAM6-FESOM performs overall favourably compared to five well-established climate models. Internal variations of the global mean surface temperature in the model are consistent with observed fluctuations and suggest that the recent warming slowdown can be explained as a once-in-one-hundred-years event caused by internal climate variability; periods of strong cooling in the model (`hiatus' analogs) are mainly associated with ENSO-related variability and to a lesser degree also to PDO shifts, with the AMO playing a minor role. Common atmospheric and oceanic variability patterns are simulated largely consistent with their real counterparts. Typical deficits also found in other models at similar resolutions remain, in particular too weak non-seasonal variability of SSTs over large parts of the ocean and episodic periods of almost absent

    This is the second of a 3-part series presenting 2 effective applications-acuity and dosage-that describe how the business case for case management (CM) can be made. In Part I, dosage and acuity concepts were explained as client need-severity, CM intervention-intensity, and CM activity-dose prescribed by amount, frequency, duration, and breadth of activities. Part I also featured a specific exemplar, the CM Acuity Tool, and described how to use acuity to identify and score the complexity of a CM case. Appropriate dosage prescription of CM activity was discussed. Part II further explains dosage and presents two acuity instruments, the Acuity Tool and AccuDiff. Details are provided that show how these applications produce opportunities for better communication about CM cases and for more accurate measurement of the right content that genuinely reflects the essentials of CM practice. The information contained in the 3-part series applies to all CM practice settings and contains ideas and recommendations useful to CM generalists, specialists, and supervisors, plus business and outcomes managers. The Acuity Tools Project was developed from frontline CM practice in one large, national telephonic CM company. Dosage: A literature search failed to find research into dosage of a behavioral intervention. The Huber-Hall model was developed and tested in a longitudinal study of CM models in substance abuse treatment and reported in the literature. Acuity: A structured literature search and needs assessment launched the development of the suite of acuity tools. A gap analysis identified that an instrument to assign and measure case acuity specific to CM activities was needed. Clinical experts, quality specialists, and business analysts (n = 7) monitored the development and testing of the tools, acuity concepts, scores, differentials, and their operating principles and evaluated the validity of the Acuity Tools' content related to CM activities.

    The Arctic Ocean simulated in 14 global ocean-sea ice models in the framework of the Coordinated Ocean-ice Reference Experiments, phase II (CORE-II) is analyzed in this study. The focus is on the Arctic liquid freshwater (FW) sources and freshwater content (FWC). The models agree on the interannual variability of liquid FW transport at the gateways where the ocean volume transport determines the FW transport variability. The variation of liquid FWC is induced by both the surface FW flux (associated with sea ice production) and lateral liquid FW transport, which are in phase when averaged on decadal time scales. The liquid FWC shows an increase starting from the mid-1990s, caused by the reduction of both sea ice formation and liquid FW export, with the former being more significant in most of the models. The mean state of the FW budget is less consistently simulated than the temporal variability. The model ensemble means of liquid FW transport through the Arctic gateways compare well with observations. On average, the models have too high mean FWC, weaker upward trends of FWC in the recent decade than the observation, and low consistency in the temporal variation of FWC spatial distribution, which needs to be further explored for the purpose of model development.

    Purpose: In the state of North Rhine-Westphalia (NRW), Germany, a survey was conducted on radiologic examinations ordered by general practitioners (GPs). Part II of this study aims to determine the quality of the process and outcome. The reference standard is the assessment of both radiologists and physicians without board certification in radiology working at a university hospital and in outpatient facilities. Materials and Methods: All GPs in NRW were asked to cooperate. Participating GPs filled out a questionnaire for each patient. The patients recorded the symptoms prompting the imaging examinations. The radiologists or other physicians performing the examinations were asked to provide the images and written reports and to complete a questionnaire. A file was created for each of the 394 patients with image documentation of at least one examination. Each file, which included medical history, physical findings, imaging documentation and written report, was sequentially forwarded to a board-certified radiologist and to a physician without board certification in radiology working in a university hospital and in an outpatient facility. All physicians were requested to complete a structured questionnaire for each file. Results: The referral diagnoses were rated as medically plausible in 81%, the indications for imaging found correct in 76%, the examination techniques considered appropriate in 69%, the clinical question answered in 63%, the interpretation judged medically correct in 50% and all incidental findings documented in 49%. In retrospect, 32% of the examinations were judged superfluous. The sequence of multiple examinations performed on a particular patient was rated as appropriate in 51%. The interpretation revealed specialty-related differences. The plausibility of the referral diagnoses had a significant impact on the appropriateness of subsequent diagnostic investigations. Marked deficits showed sonography, performance by non-radiologists, self

    We present a study of diffuse extended ionized gas towards three clouds located in the Galactic Centre (GC). One line of sight (LOS) is towards the 20 km s-1 cloud (LOS-0.11) in the Sgr A region, another LOS is towards the 50 km s-1 cloud (LOS-0.02), also in Sgr A, while the third is towards the Sgr B2 cloud (LOS+0.693). The emission from the ionized gas is detected from Hnα and Hmβ radio recombination lines (RRLs). Henα and Hemβ RRL emission is detected with the same n and m as those from the hydrogen RRLs only towards LOS+0.693. RRLs probe gas with positive and negative velocities towards the two Sgr A sources. The Hmβ to Hnα ratios reveal that the ionized gas is emitted under local thermodynamic equilibrium conditions in these regions. We find a He to H mass fraction of 0.29±0.01 consistent with the typical GC value, supporting the idea that massive stars have increased the He abundance compared to its primordial value. Physical properties are derived for the studied sources. We propose that the negative velocity component of both Sgr A sources is part of gas streams considered previously to model the GC cloud kinematics. Associated massive stars with what are presumably the closest H II regions to LOS-0.11 (positive velocity gas), LOS-0.02, and LOS+0.693 could be the main sources of ultraviolet photons ionizing the gas. The negative velocity components of both Sgr A sources might be ionized by the same massive stars, but only if they are in the same gas stream.

  13. The 183-WSL Fast Rain Rate Retrieval Algorithm. Part II: Validation Using Ground Radar Measurements

    Laviola, Sante; Levizzani, Vincenzo

    2014-01-01

    The Water vapour Strong Lines at 183 GHz (183-WSL) algorithm is a method for the retrieval of rain rates and precipitation type classification (convectivestratiform), that makes use of the water vapor absorption lines centered at 183.31 GHz of the Advanced Microwave Sounding Unit module B (AMSU-B) and of the Microwave Humidity Sounder (MHS) flying on NOAA-15-18 and NOAA-19Metop-A satellite series, respectively. The characteristics of this algorithm were described in Part I of this paper together with comparisons against analogous precipitation products. The focus of Part II is the analysis of the performance of the 183-WSL technique based on surface radar measurements. The ground truth dataset consists of 2.5 years of rainfall intensity fields from the NIMROD European radar network which covers North-Western Europe. The investigation of the 183-WSL retrieval performance is based on a twofold approach: 1) the dichotomous statistic is used to evaluate the capabilities of the method to identify rain and no-rain clouds; 2) the accuracy statistic is applied to quantify the errors in the estimation of rain rates.The results reveal that the 183-WSL technique shows good skills in the detection of rainno-rain areas and in the quantification of rain rate intensities. The categorical analysis shows annual values of the POD, FAR and HK indices varying in the range 0.80-0.82, 0.330.36 and 0.39-0.46, respectively. The RMSE value is 2.8 millimeters per hour for the whole period despite an overestimation in the retrieved rain rates. Of note is the distribution of the 183-WSL monthly mean rain rate with respect to radar: the seasonal fluctuations of the average rainfalls measured by radar are reproduced by the 183-WSL. However, the retrieval method appears to suffer for the winter seasonal conditions especially when the soil is partially frozen and the surface emissivity drastically changes. This fact is verified observing the discrepancy distribution diagrams where2the 183-WSL

    Full Text Available The paper was conceived in two parts. Part I, previously published in this journal, highlighted the main steps of adaptive output feedback control for non-affine uncertain systems, having a known relative degree. The main paradigm of this approach was the feedback linearization (dynamic inversion with neural network augmentation. Meanwhile, based on new contributions of the authors, a new paradigm, that of robust servomechanism problem solution, has been added to the controller architecture. The current Part II of the paper presents the validation of the controller hereby obtained by using the longitudinal channel of a hovering VTOL-type aircraft as mathematical model.

  17. Uncertainty estimation with a small number of measurements, part II: a redefinition of uncertainty and an estimator method

    Science.gov (United States)

    Huang, Hening

    2018-01-01

    This paper is the second (Part II) in a series of two papers (Part I and Part II). Part I has quantitatively discussed the fundamental limitations of the t-interval method for uncertainty estimation with a small number of measurements. This paper (Part II) reveals that the t-interval is an ‘exact’ answer to a wrong question; it is actually misused in uncertainty estimation. This paper proposes a redefinition of uncertainty, based on the classical theory of errors and the theory of point estimation, and a modification of the conventional approach to estimating measurement uncertainty. It also presents an asymptotic procedure for estimating the z-interval. The proposed modification is to replace the t-based uncertainty with an uncertainty estimator (mean- or median-unbiased). The uncertainty estimator method is an approximate answer to the right question to uncertainty estimation. The modified approach provides realistic estimates of uncertainty, regardless of whether the population standard deviation is known or unknown, or if the sample size is small or large. As an application example of the modified approach, this paper presents a resolution to the Du-Yang paradox (i.e. Paradox 2), one of the three paradoxes caused by the misuse of the t-interval in uncertainty estimation.

    Full Text Available Inicialmente, escuchar sobre la muerte de una mujer tras haber sido privada de su libertad y violentada sexualmente sonaba como un caso aislado en el que las circunstancias habían “pro - piciado” ese acontecimiento. La cantidad y frecuencia de tales acontecimientos, obligó a dar un significante específico para tan específico significado: feminicidio. El interés social y psicológico condujo a investigar de qué manera estos feminicidios influyen en la actitud y en las emociones de las mujeres juarenses, específicamente en los niveles de ansiedad; el presente trabajo tiene como objetivo dar a conocer los resultados obtenidos en dicha investigación. A fin de establecer la relación entre la actitud hacia los feminicidios y la ansiedad, se tomaron dos grupos de estu - dio: mujeres estudiantes de psicología (n=181 y mujeres trabajadoras de maquila (n=186, a los cuales se les aplicaron dos instrumentos de medición (Inventario de Ansiedad Rasgo-Estado e Inventario de Actitud hacia los feminicidios que permitieran: a determinar los niveles de ansiedad (rasgo-estado y los niveles de actitud hacia los feminicidios en cada grupo de estudio, b correlacionar tales niveles, y c establecer una comparación entre los resultados de cada grupo de estudio. No se encontraron diferencias significativas entre los grupos respecto a la actitud hacia los feminicidios, sin embargo, se obtuvo una diferencia significativa en los niveles más altos de ansiedad rasgo-estado presentados en las trabajadoras de maquila, respecto a los niveles de ansiedad rasgo-estado presentados en las estudiantes de psicología.

    Part I of this report presents technical justification for the use of plant-reference simulators in the licensing and training of nuclear power plant operators and examines alternatives to the use of plant-reference simulators. The technical rationale is based on research on the use of simulators in other industries, psychological learning and testing principles, expert opinion and user opinion. Part II discusses the central considerations in using plant-reference simulators for licensing examination of nuclear power plant operators and for incorporating simulators into nuclear power plant training programs. Recommendations are presented for the administration of simulator examinations in operator licensing that reflect the goal of maximizing both reliability and validity in the examination process. A series of organizational tasks that promote the acceptance, use, and effectiveness of simulator training as part of the onsite training program is delineated

    1999-11-01

    In the first part I perform Hartree-Fock calculations to show that quantum dots (i.e., two-dimensional systems of up to twenty interacting electrons in an external parabolic potential) undergo a gradual transition to a spin-polarized Wiper crystal with increasing magnetic field strength. The phase diagram and ground state energies have been determined. I tried to improve the ground state of the Wigner crystal by introducing a Jastrow ansatz for the wave function and performing a variational Monte Carlo calculation. The existence of so called magic numbers was also investigated. Finally, I also calculated the heat capacity associated with the rotational degree of freedom of deformed many-body states and suggest an experimental method to detect Wigner crystals. The second part of the thesis investigates infinite nuclear matter on a cubic lattice. The exact thermal formalism describes nucleons with a Hamiltonian that accommodates on-site and next-neighbor parts of the central, spin-exchange and isospin-exchange interaction. Using auxiliary field Monte Carlo methods, I show that energy and basic saturation properties of nuclear matter can be reproduced. A first order phase transition from an uncorrelated Fermi gas to a clustered system is observed by computing mechanical and thermodynamical quantities such as compressibility, heat capacity, entropy and grand potential. The structure of the clusters is investigated with the help two-body correlations. I compare symmetry energy and first sound velocities with literature and find reasonable agreement. I also calculate the energy of pure neutron matter and search for a similar phase transition, but the survey is restricted by the infamous Monte Carlo sign problem. Also, a regularization scheme to extract potential parameters from scattering lengths and effective ranges is investigated.

    Full Text Available La ansiedad es un proceso normal adaptativo a circunstancias que generan estrés o representan un desafío para quien la padece y puede tornarse en desadaptativa bajo algunas circunstancias. Como parte del espectro sintomático de la ansiedad, algunas de sus representaciones somáticas se relacionan con equilibrio y oído interno. Con frecuencia se encuentra relación entre la sintomatología neuropsiquiátrica y otorrinolaringológica. Las estadísticas internacionales así lo señalan. En Colombia no hay datos específicos al respecto, aunque se encuentra información de patologías individuales. El abordaje de estos pacientes debe ser integral, y con disposición de la mayor cantidad de información clínica y paraclínica posible según la sospecha diagnóstica y con el paciente, se establecen indicadores de logros reales según el caso. La causalidad o el orden de aparición de la sintomatología entre la eminentemente psiquiátrica y la otológica es variable y en muchos casos parece circular. El ver estos síntomas desde la psiquiatría o desde la otorrinolaringología es un abordaje con frecuencia insuficiente y requiere de la integración de saberes. Con ese fin se han planteado teorías explicativas en varios sentidos e incluso se han adicionado categorías diagnósticas nuevas. El tratamiento es un abanico de posibilidades que incluye la terapia física de acondicionamiento y rehabilitación vestibular, psicoterapia y farmacoterapia, dentro de la cual se recomienda el uso de inhibidores selectivos de la recaptación de serotonina.

  13. Peak-summer East Asian rainfall predictability and prediction part II: extratropical East Asia

    Science.gov (United States)

    Yim, So-Young; Wang, Bin; Xing, Wen

    2016-07-01

    The part II of the present study focuses on northern East Asia (NEA: 26°N-50°N, 100°-140°E), exploring the source and limit of the predictability of the peak summer (July-August) rainfall. Prediction of NEA peak summer rainfall is extremely challenging because of the exposure of the NEA to midlatitude influence. By examining four coupled climate models' multi-model ensemble (MME) hindcast during 1979-2010, we found that the domain-averaged MME temporal correlation coefficient (TCC) skill is only 0.13. It is unclear whether the dynamical models' poor skills are due to limited predictability of the peak-summer NEA rainfall. In the present study we attempted to address this issue by applying predictable mode analysis method using 35-year observations (1979-2013). Four empirical orthogonal modes of variability and associated major potential sources of variability are identified: (a) an equatorial western Pacific (EWP)-NEA teleconnection driven by EWP sea surface temperature (SST) anomalies, (b) a western Pacific subtropical high and Indo-Pacific dipole SST feedback mode, (c) a central Pacific-El Nino-Southern Oscillation mode, and (d) a Eurasian wave train pattern. Physically meaningful predictors for each principal component (PC) were selected based on analysis of the lead-lag correlations with the persistent and tendency fields of SST and sea-level pressure from March to June. A suite of physical-empirical (P-E) models is established to predict the four leading PCs. The peak summer rainfall anomaly pattern is then objectively predicted by using the predicted PCs and the corresponding observed spatial patterns. A 35-year cross-validated hindcast over the NEA yields a domain-averaged TCC skill of 0.36, which is significantly higher than the MME dynamical hindcast (0.13). The estimated maximum potential attainable TCC skill averaged over the entire domain is around 0.61, suggesting that the current dynamical prediction models may have large rooms to improve

  14. Impacts of Realistic Urban Heating. Part II: Air Quality and City Breathability

    2018-03-01

    Urban morphology and inter-building shadowing result in a non-uniform distribution of surface heating in urban areas, which can significantly modify the urban flow and thermal field. In Part I, we found that in an idealized three-dimensional urban array, the spatial distribution of the thermal field is correlated with the orientation of surface heating with respect to the wind direction (i.e. leeward or windward heating), while the dispersion field changes more strongly with the vertical temperature gradient in the street canyon. Here, we evaluate these results more closely and translate them into metrics of "city breathability," with large-eddy simulations coupled with an urban energy-balance model employed for this purpose. First, we quantify breathability by, (i) calculating the pollutant concentration at the pedestrian level (horizontal plane at z≈ 1.5 -2 m) and averaged over the canopy, and (ii) examining the air exchange rate at the horizontal and vertical ventilating faces of the canyon, such that the in-canopy pollutant advection is distinguished from the vertical removal of pollution. Next, we quantify the change in breathability metrics as a function of previously defined buoyancy parameters, horizontal and vertical Richardson numbers (Ri_h and Ri_v , respectively), which characterize realistic surface heating. We find that, unlike the analysis of airflow and thermal fields, consideration of the realistic heating distribution is not crucial in the analysis of city breathability, as the pollutant concentration is mainly correlated with the vertical temperature gradient (Ri_v ) as opposed to the horizontal (Ri_h ) or bulk (Ri_b ) thermal forcing. Additionally, we observe that, due to the formation of the primary vortex, the air exchange rate at the roof level (the horizontal ventilating faces of the building canyon) is dominated by the mean flow. Lastly, since Ri_h and Ri_v depend on the meteorological factors (ambient air temperature, wind speed, and

  16. Part I. Inviscid, swirling flows and vortex breakdown. Part II. A numerical investigation of the Lundgren turbulence model

    International Nuclear Information System (INIS)

    Buntine, J.D.

    1994-01-01

    Part I. A study of the behaviour of an inviscid, swirling fluid is performed. This flow can be described by the Squire-Long equation if the constraints of time-independence and axisymmetry are invoked. The particular case of flow through a diverging pipe is selected and a study is conducted to determine over what range of parameters does a solution exist. The work is performed with a view to understanding how the phenomenon of vortex breakdown develops. Experiments and previous numerical studies have indicated that the flow is sensitive to boundary conditions particularly at the pipe inlet. A open-quotes quasi-cylindricalclose quotes amplification of the Squire-Long equation is compared with the more complete model and shown to be able to account for most of its behaviour. An advantage of this latter representation is the relatively undetailed description of the flow geometry it requires in order to calculate a solution. open-quotes Criticalityclose quotes or the ability of small disturbances to propagate upstream is related to results of the quasi-cylindrical and axisymmetric flow models. This leads to an examination of claims made by researchers such as Benjamin and Hall concerning the interrelationship between open-quotes failureclose quotes of the quasi-cylindrical model and the occurrence of a open-quotes criticalclose quotes flow state. Lundgren developed an analytical model for homogeneous turbulence based on a collection of contracting spiral vortices each embedded in an axisymmetric strain field. Using asymptotic approximations he was able to deduce the Kolmogorov k -5/3 behaviour for inertial scales in the turbulence energy spectrum. Pullin ampersand Saffman have enlarged upon his work to make a number of predictions about the behaviour of turbulence described by the model. This work investigates the model numerically. The first part considers how the flow description compares with numerical simulations using the Navier-Stokes equations

    This paper is the second part of a general study about physic-geometrical and fluid-dynamics characteristic of the sugarcane bagasse particles. These properties has relevant importance on the dimensions and operation of the equipment for transport and treatment of solid particles. Was used the transport column method for the determination of the drag velocity and later on the drag coefficient of the sugarcane bagasse particles was calculated. Both, the installation and experimental technique used for materials of these characteristics are simple and innovations tools, but rigorous conceptually, thus the results obtained are reliable. Were used several sugarcane bagasse fractions of particles of known mean diameter. The properties determined were expressed as a function of Reynolds and Archimedes a dimensional criteria. The best considered model from statistical analysis (model from equation 8) was statistically validated for determined ranges of Reynolds and Archimedes. These empirical equations can be used to determine these properties in the range and conditions specified and also for modeling some processes where these fractions are employed. (author)

    Residual sodium is defined as sodium metal that remains behind in pipes, vessels, and tanks after the bulk sodium metal has been melted and drained from such components. The residual sodium has the same chemical properties as bulk sodium, and differs from bulk sodium only in the thickness of the sodium deposit. Typically, sodium is considered residual when the thickness of the deposit is less than 5-6 cm. This residual sodium must be removed or deactivated when a pipe, vessel, system, or entire reactor is permanently taken out of service, in order to make the component or system safer and/or to comply with decommissioning regulations. As an alternative to the established residual sodium deactivation techniques (steam-and-nitrogen, wet vapor nitrogen, etc.), a technique involving the use of moisture and carbon dioxide has been developed. With this technique, sodium metal is converted into sodium bicarbonate by reacting it with humid carbon dioxide. Hydrogen is emitted as a by-product. This technique was first developed in the laboratory by exposing sodium samples to humidified carbon dioxide under controlled conditions, and then demonstrated on a larger scale by treating residual sodium within the Experimental Breeder Reactor II (EBR-II) secondary cooling system, followed by the primary cooling system, respectively. The EBR-II facility is located at the Idaho National Laboratory (INL) in southeastern Idaho, U.S.A. This report is Part 1 of a two-part report. It is divided into three sections. The first section describes the chemistry of carbon dioxide-water-sodium reactions. The second section covers the laboratory experiments that were conducted in order to develop the residual sodium deactivation process. The third section discusses the application of the deactivation process to the treatment of residual sodium within the EBR-II secondary sodium cooling system. Part 2 of the report, under separate cover, describes the application of the technique to residual sodium

    Full Text Available The diversification and customization of products are important characteristic of the modern economy and especially of the fashion industry. Because of this, the lifetime of the footwear product is very short and result the necessity to cut the design and production time. By classic methodology, designing footwear is a very complex and laborious activity. That is because classic methodology requires many graphic executions using manual means, which consume a lot of the producer’s time. With CRISPIN Dynamics, one can visualize a range of designs on-screen; work out the costs of a new style and even cut out sample shoe components. Reliance on manual skills is largely eliminated, so the staff can work creatively, but with increased accuracy and productivity. One can even send designs to a distant office or manufacturing centre in a matter of minutes. This paper presents the basic function of CRISPIN Dynamics CAD Suite Engineer for footwear design. The process of new product development has six stapes: digitized form of the medium copy, last flatting, model drawing, creation and management of individual parts, estimation of material consumption, multiplying the designed footwear product’s pattern. This product has been developed for shoemakers who wish to ensure that their business remains competitive by increasing the efficiency, speed and accuracy of pattern development and grading.

Los pacientes con ansiedad odontológica tienden a descuidar el cuidado dental, lo cual plantea un problema, tanto para los pacientes como para los dentistas. Una relación dentista-paciente dominada por la ansiedad grave puede conducir a un mal diagnóstico y tratamiento inadecuado. Existen diferentes opciones de tratamiento para la ansiedad odontológica que pueden ir desde la explicación del proceso de tratamiento, estrategias farmacológicas, biofeedback, hipnosis e intervenciones conductuales. Se cree que la música reduce la ansiedad gracias a un efecto relajante o de distracción, que a su vez disminuye la actividad de los sistemas neuro-endocrino y sistema nervioso simpático.

    2011-09-01

    Full Text Available El reflejo mandibular o maseterino posee conexiones nerviosas únicas, diferentes de las exhi­bidas por otros reflejos monosinápticos humanos, y permite evaluar, de forma fácil y eficien­te, el tallo cerebral por medio de la estimulación mecánica, eléctrica o magnética. Diversos estudios han demostrado la participación en este reflejo de las interneuronas del tallo cerebral y su modulación por estructuras supraespinales, que hacen parte fundamental de su integra­ción motora. El reflejo mandibular es útil para evaluar la afectación trigémino-trigeminal en polineuropatías como la diabetes, neuromiopatías como la esclerosis múltiple y en pacientes con trastornos del movimiento, con o sin disfunción oromandibular. La evaluación neuro­funcional de este reflejo craneofacial ayuda a identificar la integración sensorimotora del tallo cerebral y las posibles alteraciones de estas vías reflejas, debidas a anormalidades del sistema nervioso central o del periférico. Su apropiada ejecución e interpretación, clínica y neurológica, permite aplicar de manera más personalizada diversos protocolos de neurorre­habilitación, con el fin de ayudar a mejorar la calidad de vida de los individuos con afectación de estas vías neurales.

  9. Programming an interim report on the SETL project. Part I: generalities. Part II: the SETL language and examples of its use

    Energy Technology Data Exchange (ETDEWEB)

    Schwartz, J T

    1975-06-01

    A summary of work during the past several years on SETL, a new programming language drawing its dictions and basic concepts from the mathematical theory of sets, is presented. The work was started with the idea that a programming language modeled after an appropriate version of the formal language of mathematics might allow a programming style with some of the succinctness of mathematics, and that this might ultimately enable one to express and experiment with more complex algorithms than are now within reach. Part I discusses the general approach followed in the work. Part II focuses directly on the details of the SETL language as it is now defined. It describes the facilities of SETL, includes short libraries of miscellaneous and of code optimization algorithms illustrating the use of SETL, and gives a detailed description of the manner in which the set-theoretic primitives provided by SETL are currently implemented.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: Reduzir a ansiedade é muito importante antes da operação. A visita no pré-operatório e a utilização de pré-medicação são os métodos mais populares para se atingir esse objetivo, mas o papel da pré-medicação ansiolítica permanece incerto e os efeitos colaterais no pós-operatório podem partir de uma pré-medicação de rotina. Citrus aurantium é usado como medicina alternativa em alguns países para tratar a ansiedade. Recentemente, o papel ansiolítico dessa planta medicinal foi estabelecido em um estudo realizado em modelo animal. O objetivo deste estudo foi avaliar o efeito ansiolítico da flor de Citrus aurantium sobre a ansiedade pré-operatória. MÉTODOS: Foram estudados 60 pacientes ASA I submetidos a uma pequena cirurgia. Em um desenho randomizado e duplo-cego, dois grupos de 30 pacientes receberam uma das seguintes MPA oral duas horas antes da indução da anestesia: 1 Citrus aurantium destilado 1 mL.kg-1 (Grupo C; 2 solução salina 1 mL.kg-1 como placebo (Grupo P. A ansiedade foi medida antes e após pré-medicação com o Inventário de Ansiedade Traço-Estado (IDATE e a Escala de Ansiedade e Informação Pré-Operatória de Amsterdam (APAIS antes da operação. RESULTADOS: Após pré-medicação, tanto o IDATE quanto as escalas APAIS estavam diminuídos no Grupo C (p < 0,05, embora não tenham apresentado alterações significativas no Grupo P. CONCLUSÕES:Citrus aurantium pode mostrar-se eficaz na redução da ansiedade pré-operatória em cirurgias de pequeno porte.

    Full Text Available Este trabajo nace con la intención de recuperar y actualizar un artículo clásico de la psicología del deporte como es el de Simon y Martens del 1979. Como su antecesor, nuestro trabajo compara la ansiedad rasgo competitiva en deportes y actividades lúdicas que se clasifican en base a dos variables de agrupación: la Colaboración, que diferencia entre actividades individuales y colectivas, y la Habilidad, que separa aquellas actividades que requieren de habilidades habituales de las que requieren de habilidades perceptivas. 643 deportistas y 140 castellers contestaron la Escala de Ansiedad Competitiva-2 y sus puntuaciones fueron comparadas mediante análisis de la varianza en función de las variables Colaboración, Habilidad y la interacción entre ambas. Los resultados indican que en aquellas actividades cuya habilidad es de tipo habitual, aparecen niveles más altos en el factor de Ansiedad Somática y Preocupación. Además, los participantes en deportes individuales relatan mayores niveles de Desconcentración que aquellos que realizan deportes o actividades colectivas. Se detecta también un efecto interactivo de las variables colaboración y habilidad sobre la Preocupación. Se ha realizado una comparación adicional deportistas y castellers, como actividad evaluativa no deportiva, revelando que el nivel de Ansiedad Somática de los castellers es equivalente al de los deportistas, pero que en las variables de Preocupación y Desconcentración los deportistas relatan niveles significativamente mayores. Finalmente se discute la importancia de conocer las características de cada modalidad deportiva de cara al trabajo específico con los entrenadores y padres para el trabajo preventivo de la ansiedad.

    2016-12-01

    Facing a malpractice lawsuit can be a daunting and traumatic experience for healthcare practitioners, with most clinicians naïve to the legal landscape. It is crucial for physicians to know and understand the malpractice system and his or her role once challenged with litigation. We present part II of a two-part series addressing the most common medicolegal questions that cause a great deal of anxiety. Part I focused upon risk-management strategies and prevention of malpractice lawsuits, whereas part II provides helpful suggestions and guidance for the physician who has been served with a lawsuit complaint. Herein, we address the best approach concerning what to do and what not to do after receipt of a legal claim, during the deposition, and during the trial phases. We also discuss routine concerns that may arise during the development of the case, including the personal, financial, and career implications of a malpractice lawsuit and how these can be best managed. The defense strategies discussed in this paper are not a guide separate from legal representation to winning a lawsuit, but may help physicians prepare for and cope with a medical malpractice lawsuit. This article is written from a US perspective, and therefore not all of the statements made herein will be applicable in other countries. Within the USA, medical practitioners must be familiar with their own state and local laws and should consult with their own legal counsel to obtain advice about specific questions.

    The debate over which health care providers are most capably meeting their responsibilities in serving the public's interest continues unabated, and the comparisons of not-for-profit (NFP) versus for-profit (FP) hospitals remain at the epicenter of the discussion. From the perspective of available factual information, which of the two sides to this debate is correct? This article is part II of a 2-part series on comparing and contrasting the performance records of NFP health care providers with their FP counterparts. Although it is demonstrated that both NFP and FP providers perform virtuous and selfless feats on behalf of America's public, it is also shown that both camps have been accused of being involved in potentially willful clinical and administrative missteps. Part I provided the background information (eg, legal differences, perspectives on social responsibility, and types of questionable and fraudulent behavior) required to adequately understand the scope of the comparison issue. Part II offers actual comparisons of the 2 organizational structures using several disparate factors such as specific organizational behaviors, approach to the health care priorities of cost and quality, and business-focused goals of profits, efficiency, and community benefit.

    Full Text Available INTRODUCTION: There is substantial evidence regarding the impact of negative life events during childhood on the aetiology of psychiatric disorders. We examined the association between negative early life events and social anxiety in a sample of 571 Spanish University students. METHODS: In a cross-sectional survey conducted in 2007, we collected data through a semistructured questionnaire of sociodemographic variables, personal and family psychiatric history, and substance abuse. We assessed the five early negative life events: (i the loss of someone close, (ii emotional abuse, (iii physical abuse, (iv family violence, and (v sexual abuse. All participants completed the Liebowitz Social Anxiety Scale. RESULTS: Mean (SD age was 21 (4.5, 75% female, LSAS score was 40 (DP = 22, 14.2% had a psychiatric family history and 50.6% had negative life events during childhood. Linear regression analyses, after controlling for age, gender, and family psychiatric history, showed a positive association between family violence and social score (p = 0.03. None of the remaining stressors produced a significant increase in LSAS score (p > 0.05. CONCLUSION: University students with high levels of social anxiety presented higher prevalence of negative early life events. Thus, childhood family violence could be a risk factor for social anxiety in such a population.INTRODUÇÃO: Existem evidências substanciais sobre o impacto de eventos negativos da vida durante a infância na etiologia dos transtornos psiquiátricos.

    Recent emphases have been directed by Federal government regulatory agencies and other research groups on the carcinogenic effects of certain aromatic hydrocarbon components in naturally occurring petroleum products. These are used in plant operations, and underline the importance of evaluating environments. Since Rocky Flats Plant uses large quantities of fuel oil, the author was prompted to undertake a search of the chemical literature. Articles and accounts of studies were reviewed on nonbiological laboratory methods for determining the carcinogenicity of residual fuel oils and related high-boiling petroleum fractions. The physical and chemical methods involve the separation or measurement (or both) of polynuclear aromatic constituents which generally are responsible for the carcinogenic effects. Thus, the author suggests that the total carcinogenic activity of any petroleum product may not be due to a specific potent carcinogen, but rather to the cumulative effect of several individually weak carcinogens. The literature search is presented as an annotated bibliography, current as of January 1, 1975, and includes significant parts of the studies along with the total number of other references found when the citation was examined in its entirety. Part I deals with laboratory chemical and physical methods of determining carcinogenicity or polynuclear aromatic hydrocarbons (or both) in residual fuel oils and contains ten entries. Part II includes the results of testing specific fuel oils for carcinogenic constituents and contains eleven entries. An author index and subject categories are included.

    2008-02-01

    Patients with cutaneous markers in the lumbo-sacral region as well as infants with bladder and bowel dysfunction, orthopedic anomalies and progressive neurological dysfunction are at risk for spinal dysraphism and tethered cord. Three types of spinal dysraphism can be distinguished: Type I - open spinal dysraphisms with a non-skin covered back mass; type II - closed spinal dysraphisms with a skin covered back mass; type III - occult spinal dysraphisms without a back mass. All spinal dysraphisms can be associated with a tethered cord, characterized by a low position of the conus medullaris below L3. Type I dysraphisms are meningomyeloceles and myeloceles, which are associated with CHIARI-II malformations characterized by the low position of the cerebellar vermis within the foramen magnum. Type II dysraphisms are lipomyeloceles, lipomyelomeningoceles, posterior meningoceles and myelocystoceles. Lipomeningoceles and lipomyelomeningoceles are characterized by a subcutaneous echogenic mass which communicates with the spinal canal and may cause tethered cord. Posterior meningoceles are, dorsal cystic space occupying lesions without internal neural tissue. Myelocystoceles are characterized by a cystic dorsal mass which communicates with a dilated central canal characteristic of syringo-hydromyelia. Type III dysraphisms without a back mass are frequently associated with cutaneous markers in the lumbo-sacral region. Sonographically dermal sinus tracts, diastematomyelia, tight filum and lipoma of the filum terminale and the caudal regression syndrome have to be distinguished. Dermal sinuses are characterized by an echogenic tract from the skin to the spinal canal, often associated with a spinal dermoid. Diastematomyelia is characterized by a complete or partial duplication of the spinal cord which can only be shown on axial images. Tight filum terminale or lipoma of the filum terminale is characterized by a thick echogenic filum with a diameter of more than 2 mm, and a conus

    Full Text Available RESUMO Introdução: O uso de substâncias psicoativas é uma prática milenar e universal, que acompanha a história da humanidade. Na atualidade, o crack se alastrou pelo mundo por ter maior potencial de dependência comparado a outras drogas, visto que os usuários apresentam dificuldade para interromper o uso do crack, enfrentar o craving e a ansiedade. É essencial que haja uma abordagem multidisciplinar e integral do usuário, com a utilização de técnicas cognitivo-comportamentais que enfoquem as estratégias de prevenção de recaída. Nesse contexto, os jogos cooperativos (JC e o relaxamento respiratório (RR constituem possíveis estratégias para manejo terapêutico. Objetivo: Avaliar a utilização dos JC e do RR como estratégias de enfrentamento do craving e da ansiedade em usuários de crack em situação de dependência. Método: Trata-se de uma pesquisa exploratória, quase experimental, com abordagem quantitativa, desenvolvida em uma unidade de desintoxicação para dependência química do estado da Paraíba. Resultados: A amostra foi constituída por 40 colaboradores dependentes de crack, com idade superior a 18 anos. Para avaliação dos efeitos dos JC e do RR sobre o craving e a ansiedade foram utilizados os seguintes instrumentos: Cocaine Craving Questionnaire-Brief (CCQ-B e o Inventário de Ansiedade Traço-Estado (IDATE-E. Os resultados demonstraram que os JC e o RR reduziram os escores do craving total e da ansiedade. Quanto ao fator F1, apenas os JC apresentaram resultados satisfatórios. Conclusão: Os JC e o RR demonstraram eficácia como estratégias de enfrentamento do craving e ansiedade em usuários de crack em situação de dependência nas condições em que o estudo foi desenvolvido.

    Aline Hessel de Araújo

    Full Text Available Resumo Situações de avaliação geram ansiedade e dentre elas está a prova prática de direção para a obtenção da licença para dirigir, essa ansiedade pode perturbar o desempenho e impedir a obtenção da habilitação. O presente estudo visou analisar: (a a fundamentação teórica que embasa a intervenção terapêutica em casos de ansiedade em avaliações e provas; e (b o processo terapêutico de uma cliente que procurou terapia comportamental após tentativas fracassadas na obtenção da licença para dirigir. A relevância da análise funcional da ansiedade e dos repertórios de enfrentamento da ansiedade foi considerada. Em seguida, um estudo de caso foi relatado: uma paciente com um histórico de seis reprovações no teste prático para a obtenção da licença para dirigir e níveis altos de ansiedade. Esse estudo demonstrou que um preparo apropriado e a intervenção terapêutica contribuíram para reduzir a ansiedade e promover a condição necessária para a obtenção da licença para dirigir. Estudos adicionais deverão ser realizados de modo a se obter uma melhor compreensão da relação entre a ansiedade e o desempenho, especialmente no que diz respeito ao processo de obtenção de uma licença para dirigir.

    This document is the second of a two-part report. Part 1 reviewed several demonstrations of transactive control and compared them in terms of their payoff functions, control decisions, information privacy, and mathematical solution concepts. It was suggested in Part 1 that these four listed components should be adopted for meaningful comparison and design of future transactive systems. Part 2 proposes qualitative and quantitative metrics that will be needed to compare alternative transactive systems. It then uses the analysis and design principles from Part 1 while conducting more in-depth analysis of two transactive demonstrations: the American Electric Power (AEP) gridSMART Demonstration, which used a double –auction market mechanism, and a consensus method like that used in the Pacific Northwest Smart Grid Demonstration. Ultimately, metrics must be devised and used to meaningfully compare alternative transactive systems. One significant contribution of this report is an observation that the decision function used for thermostat control in the AEP gridSMART Demonstration has superior performance if its decision function is recast to more accurately reflect the power that will be used under for thermostatic control under alternative market outcomes.

  13. Arbitrary order 2D virtual elements for polygonal meshes: part II, inelastic problem

    Science.gov (United States)

    Artioli, E.; Beirão da Veiga, L.; Lovadina, C.; Sacco, E.

    2017-10-01

    The present paper is the second part of a twofold work, whose first part is reported in Artioli et al. (Comput Mech, 2017. doi: 10.1007/s00466-017-1404-5), concerning a newly developed Virtual element method (VEM) for 2D continuum problems. The first part of the work proposed a study for linear elastic problem. The aim of this part is to explore the features of the VEM formulation when material nonlinearity is considered, showing that the accuracy and easiness of implementation discovered in the analysis inherent to the first part of the work are still retained. Three different nonlinear constitutive laws are considered in the VEM formulation. In particular, the generalized viscoelastic model, the classical Mises plasticity with isotropic/kinematic hardening and a shape memory alloy constitutive law are implemented. The versatility with respect to all the considered nonlinear material constitutive laws is demonstrated through several numerical examples, also remarking that the proposed 2D VEM formulation can be straightforwardly implemented as in a standard nonlinear structural finite element method framework.

    Full Text Available JUSTIFICATIVA E OBJETIVOS: A ansiedade pré-operatória na criança é caracterizada por tensão, apreensão, nervosismo e preocupação e pode ser expressa de diversas formas. Alterações de comportamento no pós-operatório como enurese noturna, distúrbios alimentares, apatia, insônia, pesadelos e sono agitado podem ser resultado desta ansiedade. Em algumas crianças, estas alterações persistem por até um ano. O objetivo deste trabalho é avaliar os aspectos envolvidos com a ansiedade que afeta a criança e os pais durante o período que antecede a cirurgia, bem como as intervenções, farmacológicas ou não, para reduzi-la. CONTEÚDO: O artigo aborda a ligação entre a ansiedade pré-operatória em crianças e as alterações de comportamento que podem ocorrer no período pós-operatório, bem como a influência de variáveis como idade, temperamento, experiência hospitalar prévia e dor. Medidas para reduzir a ansiedade pré-operatória na criança como a presença dos pais durante a indução da anestesia ou programas de informação e a utilização de medicação pré-anestésica também são revisadas. CONCLUSÕES: O período que antecede a cirurgia acompanha-se de grande carga emocional para toda família, sobretudo para a criança. Um pré-operatório turbulento significa, para muitas crianças, alterações de comportamento que se manifestam de forma variada e por períodos prolongados em algumas vezes. A presença dos pais durante a indução da anestesia e programas de preparação pré-operatórios para a criança e para os pais podem ser úteis para casos selecionados, levando em conta a idade, temperamento e experiência hospitalar prévia. A medicação pré-anestésica com benzodiazepínicos, em especial o midazolam, é claramente o método mais eficaz para redução da ansiedade pré-operatória em crianças e das alterações de comportamento por ela induzidas.JUSTIFICATIVA Y OBJETIVOS: La ansiedad pre-operatoria en

    The energy absorbing liner of safety helmets was optimised using finite element modelling. In this present paper, a functionally graded foam (FGF) liner was modelled, while keeping the average liner density the same as in a corresponding reference single uniform density liner model. Use of a functionally graded foam liner would eliminate issues regarding delamination and crack propagation between interfaces of different density layers which could arise in liners with discrete density variations.

    2014-10-01

    By using the abstract structures investigated in the first Part of this article, we develop a semantics for an epistemic language, which expresses sentences like "Alice knows that Bob does not understand that π is irrational". One is dealing with a holistic form of quantum computational semantics, where entanglement plays a fundamental role; thus, the meaning of a global expression determines the contextual meanings of its parts, but generally not the other way around. The epistemic situations represented in this semantics seem to reflect some characteristic limitations of the real processes of acquiring information. Since knowledge is not generally closed under logical consequence, the unpleasant phenomenon of logical omniscience is here avoided.

    This paper is the second part of a two-part series where the first part presents a molecular dynamics model of a single Boron Nitride Nanotube (BNNT) and this paper scales up to multiple BNNTs in a polymer matrix. This paper presents finite element (FE) models to investigate the effective elastic and piezoelectric properties of (BNNT) nanocomposites. The nanocomposites studied in this paper are thin films of polymer matrix with aligned co-planar BNNTs. The FE modelling approach provides a computationally efficient way to gain an understanding of the material properties. We examine several FE models to identify the most suitable models and investigate the effective properties with respect to the BNNT volume fraction and the number of nanotube walls. The FE models are constructed to represent aligned and randomly distributed BNNTs in a matrix of resin using 2D and 3D hollow and 3D filled cylinders. The homogenisation approach is employed to determine the overall elastic and piezoelectric constants for a range of volume fractions. These models are compared with an analytical model based on Mori-Tanaka formulation suitable for finite length cylindrical inclusions. The model applies to primarily single-wall BNNTs but is also extended to multi-wall BNNTs, for which preliminary results will be presented. Results from the Part 1 of this series can help to establish a constitutive relationship for input into the finite element model to enable the modeling of multiple BNNTs in a polymer matrix.

    1996-04-01

    In a recently reported study, the pretreatment records of each subject in a randomized clinical trial of 148 patients with Class I and Class II malocclusions presenting for orthodontic treatment were evaluated independently by five experienced clinicians (drawn from a panel of 14). The clinicians displayed a higher incidence of agreement with each other than had been expected with respect to the decision as to whether extraction was indicated in each specific case. To improve our understanding of how clinicians made their decisions on whether to extract or not, the records of a subset of 72 subjects randomly selected from the full sample of 148, have now been examined in greater detail. In 21 of these cases, all five clinicians decided to treat without extraction. Among the remaining 51 cases, there were 202 decisions to extract (31 unanimous decision cases and 20 split decision cases). The clinicians cited a total of 469 reasons to support these decisions. Crowding was cited as the first reason in 49% of decisions to extract, followed by incisor protrusion (14%), need for profile correction (8%), Class II severity (5%), and achievement of a stable result (5%). When all the reasons for extraction in each clinician's decision were considered as a group, crowding was cited in 73% of decisions, incisor protrusion in 35%, need for profile correction in 27%, Class II severity in 15% and posttreatment stability in 9%. Tooth size anomalies, midline deviations, reduced growth potential, severity of overjet, maintenance of existing profile, desire to close the bite, periodontal problems, and anticipation of poor cooperation accounted collectively for 12% of the first reasons and were mentioned in 54% of the decisions, implying that these considerations play a consequential, if secondary, role in the decision-making process. All other reasons taken together were mentioned in fewer than 20% of cases. In this sample at least, clinicians focused heavily on appearance

    Information regarding the differences in translucency among new ceramic systems is lacking. The purpose of this study was to compare the relative translucency of the different types of ceramic systems indicated for porcelain veneers and to evaluate the effect of shade and thickness on translucency. Disk specimens 13 mm in diameter and 0.7-mm thick were fabricated for the following 9 materials (n=5): VITA VM9, IPS Empress Esthetic, VITA PM9, Vitablocks Mark II, Kavo Everest G-Blank, IPS Empress CAD, IPS e.max CAD, IPS e.maxPress, and Lava Zirconia. VITA VM9 served as the positive control and Lava as the negative control. The disks were fabricated with the shade that corresponds to A1. For IPS e.maxPress, additional disks were made with different shades (BL2, BL4, A1, B1, O1, O2, V1, V2, V3), thickness (0.3 mm), and translucencies (high translucency, low translucency). Color coordinates (CIE L∗ a∗ b∗) were measured with a tristimulus colorimeter. The translucency parameter was calculated from the color difference of the material on a black versus a white background. One-way ANOVA, the post hoc Tukey honestly significant difference, and the Ryan-Einot-Gabriel-Welsch multiple range tests were used to analyze the data (α=.05). Statistically significant differences in the translucency parameter were found among porcelains (PPM9, Empress Esthetic>Empress CAD>Mark II, Everest, e.max CAD>e.max Press>Lava. Significant differences also were noted when different shades and thickness were compared (Pceramic systems designed for porcelain veneers present varying degrees of translucency. The thickness and shade of lithium disilicate ceramic affect its translucency. Shade affects translucency parameter less than thickness.

    The technical and financial performance of high yield Eucalyptus biomass in a co-current dilute acid pretreatment followed by enzymatic hydrolysis process was simulated using WinGEMS registered and Excel registered . Average ethanol yield per dry Mg of Eucalyptus biomass was approximately 347.6 L of ethanol (with average carbohydrate content in the biomass around 66.1%) at a cost of 0.49 L -1 of ethanol, cash cost of ∝0.46 L -1 and CAPEX of 1.03 L -1 of ethanol. The main cost drivers are: biomass, enzyme, tax, fuel (gasoline), depreciation and labor. Profitability of the process is very sensitive to biomass cost, carbohydrate content (%) in biomass and enzyme cost. Biomass delivered cost was simulated and financially evaluated in Part I; here in Part II the conversion of this raw material into cellulosic ethanol using the dilute acid process is evaluated.

    In addition to guidelines focusing on scientific evidence, practical recommendations on fertility preservation are also needed. A selective literature search was performed based on the clinical and scientific experience of the authors. This article (Part II) focuses on fertility preservation techniques. Part I, also published in this journal, provides information on disease prognosis, disease-specific therapy, and risks for loss of fertility. Ovarian stimulation including double stimulation and freezing of oocytes is the best-established therapy providing live birth chances in women preservation in women provides realistic chances of becoming pregnant. The choice of technique needs to be based on the time required, the woman's age, its risks and efficacy, and the individual preference of the patient.

    The evidence for hypothesizing a relationship between hemodynamics and atherogenesis as well as the motivation for selecting the carotid bifurcation for extensive fluid dynamic studies has been discussed in Part I of this two-paper sequence. Part II deals with velocity measurements within the bifurcation model described by Fig. 1 and Table 1 of the previous paper. A plexiglass model conforming to the dimensions of the average carotid bifurcation was machined and employed for velocity measurements with a laser-Doppler anemometer (LDA). The objective of this phase of the study was to obtain quantitative information on the velocity field and to estimate levels and directions of wall shear stress in the region of the bifurcation.

    superior em estádios mais avançados da DPOC, chegando a atingir taxas de 62% em doentes a fazer oxigenoterapia de longa duração. Também em doentes a recuperar de uma exacerbação, a percentagem de depressão e ansiedade aumentam para níveis próximos dos 50%.Os inquéritos utilizados na detecção de sintomas de ansiedade e depressão foram o PRIME-MD, Beck Depression Inventory – II e Beck Anxiety Inventory. O primeiro questionário apresenta um valor preditivo positivo bom na detecção destas afecções.A depressão pode ser um factor preditivo de fadiga, dispneia e descondicionamento físico e mortalidade, em doentes com insuficiência cardíaca ou DPOC. Inclusive, possui um papel preponderante nas decisões do doente em estádio terminal da DPOC, que quando deprimido opta na maioria dos casos pela não ressuscitação.A ansiedade e a depressão não tratadas aumentam a incapacidade física, a morbilidade e o consumo de recursos médicos. Os doentes, médicos e o sistema de saúde são muitas vezes responsáveis pela baixa taxa de diagnóstico destas alterações na DPOC.Existem vários trabalhos que comprovam a eficácia da intervenção farmacológica e não farmacológica no controlo destas comorbilidades em doentes com DPOC, contudo apenas uma pequena percentagem recebe tratamento eficaz.Os autores concluem que é necessária maior investigação nesta área, detecção precoce e tratamento da ansiedade e depressão nos doentes com DPOC.

    1984-01-01

    Part I. This is an investigation of the role of metabolism in the induction of lung injury by N-methylthiobenzamide (NMTB). N-methylthiobenzamide S-oxide (NMTBSO), a metabolite of NMTB, was prepared and found to produce lung injury that was qualitatively identical to that of NMTB. 1-methyl-1-phenyl-3-benzoylthiourea (MPBTU) protected rodents from lethal doses of either NMTB or NMTBSO. MPBTU also blocked the increases in pulmonary 14 C-thymidine incorporation induced by these compounds. Both NMTB and NMTBSO were found to undergo oxidation when incubated with either lung or liver microsomes and an NADPH-generating system. The in vitro microsomal oxidation of NMTB and NMTBSO was markedly inhibited by addition of MPBTU. These data suggest that oxidation of NMTB is required for the expression of NMTB-induced pneumotoxicity. Part II. Methylcyclopentadienyl Manganese Tricarbonyl (MMT) has been used as an antiknock additive in unleaded gasoline. Rats treated with MMT exhibit severe convulsions accompanied by hemorrhagic pulmonary edema. The purpose of this study was to investigate the possible role of neurogenic mechanisms in MMT-induced hemorrhagic pulmonary edema

    2007-07-01

    Anorexia nervosa as a psychiatric disorder presents itself through the concreteness of symptoms. Emotions are experienced as a corporeality here-and-now. In a companion article, Part I, different 'body metaphors' are described and categorised. The human body functions as metaphor, and in anorexia nervosa there is a striking closeness between emotions and different bodily experiences. This is interpreted as impaired 'reflective function', referring to the capacity to make mental representations, and is proposed as a central psychopathological feature. The psychodynamic concepts 'concretised metaphors' and 'psychic equivalence' are discussed as useful tools to better understand such compromised symbolic capacity. Psychotherapy in anorexia nervosa can be described as a relational process where concretised metaphors will be developed into genuine linguistic ones. Part III in this series of articles presents an outline for psychotherapy for anorexia nervosa. 2007 John Wiley & Sons, Ltd and Eating Disorders Association

    Full Text Available Juvenile spondyloarthropathies are mainly manifested by symptoms of peripheral arthritis and enthesitis. Early involvement of sacroiliac joints and spine is exceptionally rare in children; this usually happens in adulthood. Conventional radiographs visualize late inflammatory lesions. Early diagnosis is possible with the use of ultrasonography and magnetic resonance imaging. The first part of the article presented classifications and radiographic presentation of juvenile spondyloarthropathies. This part discusses changes seen on ultrasonography and magnetic resonance imaging. In patients with juvenile spondyloarthropathies, these examinations are conducted to diagnose inflammatory lesions in peripheral joints, tendon sheaths, tendons and bursae. Moreover, magnetic resonance also shows subchondral bone marrow edema, which is considered an early sign of inflammation. Ultrasonography and magnetic resonance imaging do not show specific lesions for any rheumatic disease. Nevertheless, they are conducted for early diagnosis, treatment monitoring and identifying complications. This article presents a spectrum of inflammatory changes and discusses the diagnostic value of ultrasonography and magnetic resonance imaging.

    Highlights: • Custom-built high temperature, high pressure tribometer is designed. • Two different wear phenomena at high temperatures are observed. • Experimental wear results for graphite are presented. • The graphite wear dust production in a typical Pebble Bed Reactor is predicted. -- Abstract: This paper is the continuation of Part I, which describes the high temperature and high pressure helium environment wear tests of graphite–graphite in frictional contact. In the present work, it has been attempted to simulate a Pebble Bed Reactor core environment as compared to Part I. The experimental apparatus, which is a custom-designed tribometer, is capable of performing wear tests at PBR relevant higher temperatures and pressures under a helium environment. This environment facilitates prediction of wear mass loss of graphite as dust particulates from the pebble bed. The experimental results of high temperature helium environment are used to anticipate the amount of wear mass produced in a pebble bed nuclear reactor.

    When planning a prosthetic rehabilitation of a periodontally compromised case, the clinician is often confronted with difficulties and dilemmas related to selecting the appropriate treatment that would provide long-term successful outcomes in function and esthetics. In such cases, a correct diagnosis and prognosis of the intraoral situation supported by evidence-based dentistry is the basis for the establishment of a proper treatment strategy. In this second part of a two-part treatment planning series, a systematic approach of patient examination and prognosis of each tooth is presented. Furthermore, different removable and fixed treatment possibilities are described and the rationale governing the decision-making process is revealed. The execution of the final treatment plan as specified by the concept of comprehensive dental care is outlined, and the final outcome is discussed according to the literature.

    Hardy, B; Donald L. Anton, D

    2008-12-22

    There is significant interest in hydrogen storage systems that employ a media which either adsorbs, absorbs or reacts with hydrogen in a nearly reversible manner. In any media based storage system the rate of hydrogen uptake and the system capacity is governed by a number of complex, coupled physical processes. To design and evaluate such storage systems, a comprehensive methodology was developed, consisting of a hierarchical sequence of models that range from scoping calculations to numerical models that couple reaction kinetics with heat and mass transfer for both the hydrogen charging and discharging phases. The scoping models were presented in Part I [1] of this two part series of papers. This paper describes a detailed numerical model that integrates the phenomena occurring when hydrogen is charged and discharged. A specific application of the methodology is made to a system using NaAlH{sub 4} as the storage media.

    By the development of information theory in 1948 by Claude Shannon to address the problems in the field of data storage and data communication over (noisy) communication channel, it has been successfully applied in many other research areas such as bioinformatics and systems biology. In this manuscript, we attempt to review some of the existing literatures in systems biology, which are using the information theory measures in their calculations. As we have reviewed most of the existing information-theoretic methods in gene regulatory and metabolic networks in the first part of the review, so in the second part of our study, the application of information theory in other types of biological networks including protein-protein interaction and signaling networks will be surveyed.

    2004-01-01

    This section of a two-part series on musculoskeletal disorders associated with HIV infection and AIDS reviews the non-infectious musculoskeletal conditions. In the first part, the infectious conditions were reviewed. The non-infectious conditions include polymyositis, drug-induced myopathy, myositis ossificans, adhesive capsulitis, avascular necrosis, bone marrow abnormalities, and hypertrophic osteoarthropathy. Inflammatory and reactive arthropathies are more prevalent in HIV-positive individuals, and a separate section is dedicated to these conditions, including Reiter's syndrome, psoriatic arthritis, HIV-associated arthritis, painful articular syndrome, and acute symmetric polyarthritis. Lastly, we include a discussion of HIV-related neoplastic processes that affect the musculoskeletal system, namely Kaposi's sarcoma and non-Hodgkin's lymphoma. (orig.)

    A better integration of the information conveyed by traces within intelligence-led framework would allow forensic science to participate more intensively to security assessments through forensic intelligence (part I). In this view, the collection of data by examining crime scenes is an entire part of intelligence processes. This conception frames our proposal for a model that promotes to better use knowledge available in the organisation for driving and supporting crime scene examination. The suggested model also clarifies the uncomfortable situation of crime scene examiners who must simultaneously comply with justice needs and expectations, and serve organisations that are mostly driven by broader security objectives. It also opens new perspective for forensic science and crime scene investigation, by the proposal to follow other directions than the traditional path suggested by dominant movements in these fields.

    2016-01-01

    Development of objective measurements is an important requirement for establishing performance-based standards for protective clothing used while handling pesticide. This study, the second in a two-part series, reports on the work completed to evaluate the performance of approximately 100 fabrics that are either used or have the potential to be used for garments worn by operators while applying pesticides. Part I, published separately, provides an overview of these issues and describes research undertaken to select a test chemical for use in subsequent studies. The goals of this study were first to develop a comprehensive approach to evaluate the performance of garments currently being used by pesticide operators, and second, to use the laboratory and field data in the development of performance specifications.

  9. 'Forms of energy', an intermediary language on the road to thermodynamics? Part II

    Science.gov (United States)

    Kaper, Wolter H.; Goedhart, Martin J.

    2002-02-01

    In secondary education, 'energy' is often introduced by distinguishing different 'forms of energy' for different phenomena. Of these forms of energy, only kinetic and potential energy are accepted in current science. The question has been raised whether 'forms of energy' should be eliminated from secondary school science curricula. As a contribution to this discussion we have analysed 'forms of energy' language for inconsistencies and limitations of validity in Part I. In this second part, results are presented of two teaching experiments at university level, each involving five students. In these experiments attempts are made to build on students 'forms of energy' language as well as to challenge its limitations. Details of student and teacher reasoning are presented. The conclusion is drawn that 'forms of energy' language must be reformulated before it can be evaluated with reference to experience. A reformulation in terms of 'value' (cf. Scheler 1997) proved to be productive.

    Full Text Available The results of the first Russian study of toilet habits formation in children have been obtained. The article was planned to be published in 2 subsequent parts due to the extensiveness of the material. This article is the 2nd part*. It presents and comments on the remaining part of results in the form of the connection between main parameters and characteristics of toilet habits training processes and physiological, psychological and social factors; it also presents the discussion and conclusions. Comparative data (with foreign studies is given. A multitude of both physiological and social factors affect the process of children’s toilet habits training. The following physiological factors have been revealed: stool frequency, physiological involuntary night urination, peculiarities of falling asleep and pernicious habits – processes, which reflect the intestinal motility regulation and defecation states, urination control and neuropsychic activity. The selected training strategy and tactics, style of communication with a child also affect the training process. The most influential family-social factors in terms of toilet habits training processes are: two- or one-parent family, mother’s education and twins in the family. 

  19. Microstructural Features Controlling Mechanical Properties in Nb-Mo Microalloyed Steels. Part II: Impact Toughness

    Science.gov (United States)

    Isasti, Nerea; Jorge-Badiola, Denis; Taheri, Mitra L.; Uranga, Pello

    2014-10-01

    The present paper is the final part of a two-part paper where the influence of coiling temperature on the final microstructure and mechanical properties of Nb-Mo microalloyed steels is described. More specifically, this second paper deals with the different mechanisms affecting impact toughness. A detailed microstructural characterization and the relations linking the microstructural parameters and the tensile properties have already been discussed in Part I. Using these results as a starting point, the present work takes a step forward and develops a methodology for consistently incorporating the effect of the microstructural heterogeneity into the existing relations that link the Charpy impact toughness to the microstructure. In conventional heat treatments or rolling schedules, the microstructure can be properly described by its mean attributes, and the ductile-brittle transition temperatures measured by Charpy tests can be properly predicted. However, when different microalloying elements are added and multiphase microstructures are formed, the influences of microstructural heterogeneity and secondary hard phases have to be included in a modified equation in order to accurately predict the DB transition temperature in Nb and Nb-Mo microalloyed steels.

    Full Text Available Traditional medicine has a history extending back to thousands of years, and during the intervening time, man has identified the healing properties of a very broad range of plants. Globally, the use of herbal therapies to treat and manage cardiovascular disease (CVD is on the rise. This is the second part of our comprehensive review where we discuss the mechanisms of plants and herbs used for the treatment and management of high blood pressure. Similar to the first part, PubMed and ScienceDirect databases were utilized, and the following keywords and phrases were used as inclusion criteria: hypertension, high blood pressure, herbal medicine, complementary and alternative medicine, endothelial cells, nitric oxide, vascular smooth muscle cell (VSMC proliferation, hydrogen sulfide, nuclear factor kappa-B, oxidative stress and epigenetics/epigenomics. Each of the aforementioned keywords was co-joined with plant or herb in question, and where possible with its constituent molecule(s. This part deals in particular with plants that are used, albeit less frequently, for the treatment and management of hypertension. We then discuss the interplay between herbs/prescription drugs and herbs/epigenetics in the context of this disease. The review then concludes with a recommendation for more rigorous, well-developed clinical trials to concretely determine the beneficial impact of herbs and plants on hypertension and a disease-free living.

    Full Text Available In the paper, a study is performed from the perspective of giving a method to reduce the conservatism of the well known PIO (Pilot-Induced Oscillation criteria in predicting the susceptibility of an aircraft to this very harmful phenomenon. There are three interacting components of a PIO – the pilot, the vehicle, and the trigger (in fact, the hazard. The study, conceived in two parts, aims to underline the importance of human pilot model involved in analysis. In this first part, it is shown, following classical sources, how the LQG theory of control and estimation is used to obtain a complex model of human pilot. The approach is based on the argument, experimentally proved, that the human behaves “optimally” in some sense, subject to his inherent psychophysical limitations. The validation of such model is accomplished based on the experimental model of a VTOL-type aircraft. Then, the procedure of inserting typical saturation nonlinearities in the open loop transfer function is presented. A second part of the paper will illustrate PIO tendencies evaluation by means of a grapho-analytic method.

    2008-07-01

    Full Text Available Regardless of the application domain and deployment scope, the ability to retrieve information is critical to the successful functioning of any wireless sensor network (WSN system. In general, information extraction procedures can be categorized into three main approaches: agent-based, query-based and macroprogramming led. Whilst query-based systems are the most popular, macroprogramming techniques provide a more general-purpose approach to distributed computation. Finally, the agent-based approaches tailor the information extraction mechanism to the type of information needed and the configuration of the network it needs to be extracted from. This suite of three papers (Part I-III offers an extensive survey of the literature in the area of WSN information extraction, covering in Part I and Part II the three main approaches above. Part III highlights the open research questions and issues faced by deployable WSN system designers and discusses the potential benefits of both in-network processing and complex querying for large scale wireless informational systems.

  10. Hybrid infrared scene projector (HIRSP): a high dynamic range infrared scene projector, part II

    Science.gov (United States)

    Cantey, Thomas M.; Bowden, Mark; Cosby, David; Ballard, Gary

    2008-04-01

    This paper is a continuation of the merging of two dynamic infrared scene projector technologies to provide a unique and innovative solution for the simulation of high dynamic temperature ranges for testing infrared imaging sensors. This paper will present some of the challenges and performance issues encountered in implementing this unique projector system into a Hardware-in-the-Loop (HWIL) simulation facility. The projection system combines the technologies of a Honeywell BRITE II extended voltage range emissive resistor array device and an optically scanned laser diode array projector (LDAP). The high apparent temperature simulations are produced from the luminescent infrared radiation emitted by the high power laser diodes. The hybrid infrared projector system is being integrated into an existing HWIL simulation facility and is used to provide real-world high radiance imagery to an imaging infrared unit under test. The performance and operation of the projector is presented demonstrating the merit and success of the hybrid approach. The high dynamic range capability simulates a 250 Kelvin apparent background temperature to 850 Kelvin maximum apparent temperature signatures. This is a large increase in radiance projection over current infrared scene projection capabilities.

    Full Text Available In this study, to investigate and understand the nature of fracture behavior properly under in-plane mixed mode (Mode-I/II loading, three-dimensional fracture analyses and experiments of compact tension shear (CTS specimen are performed under different mixed mode loading conditions. Al 7075-T651 aluminum machined from rolled plates in the L-T rolling direction (crack plane is perpendicular to the rolling direction is used in this study. Results from finite element analyses and fracture loads, crack deflection angles obtained from the experiments are presented. To simulate the real conditions in the experiments, contacts are defined between the contact surfaces of the loading devices, specimen and loading pins. Modeling, meshing and the solution of the problem involving the whole assembly, i.e., loading devices, pins and the specimen, with contact mechanics are performed using ANSYSTM. Then, CTS specimen is analyzed separately using a submodeling approach, in which three-dimensional enriched finite elements are used in FRAC3D solver to calculate the resulting stress intensity factors along the crack front. Having performed the detailed computational and experimental studies on the CTS specimen, a new specimen type together with its loading device is also proposed that has smaller dimensions compared to the regular CTS specimen. Experimental results for the new specimen are also presented.

    on the implementation details but also establish finite convergence of the branch-and-bound method. The algorithm is based on solving a sequence of continuous non-convex relaxations which can be formulated as quadratic programs according to the theory in Part I. The quadratic programs to be treated within the branch......-and-bound search all have the same feasible set and differ from each other only in the objective function. This is one reason for making the resulting branch-and-bound method very efficient. The paper closes with several large-scale numerical examples. These examples are, to the knowledge of the authors, by far...

  17. Coupled Vibration of Unshrouded Centrifugal Compressor Impellers. Part II: Computation of Vibration Behavior

    Directory of Open Access Journals (Sweden)

    Dirk Hagelstein

    2000-01-01

    Full Text Available The increased use of small gas turbines and turbochargers in different technical fields has led to the development of highly-loaded centrifugal compressors with extremely thin blades. Due to high rotational speed and the correspondingly high centrifugal loads, the shape of the impeller hub must also be optimized. This has led to a reduction of the thickness of the impeller disc in the outlet region. The thin parts of the impeller are very sensitive and may be damaged by the excitation of dangerous blade vibrations.

    Sorption of Zn(II) to hematite nanoparticles (HN) (av diam=10.5 nm) and microparticles (HM) (av diam=550 nm) was studied in the presence of oxalate anions (Ox2-(aq)) in aqueous solutions as a function of total Zn(II)(aq) to total Ox2-(aq) concentration ratio (R=[Zn(II)(aq)]tot/[Ox2-(aq)]tot) at pH 5.5. Zn(II) uptake is similar in extent for both the Zn(II)/Ox/HN and Zn(II)/Ox/HM ternary systems and the Zn(II)/HN binary system at [Zn(II)(aq)](tot)system than for the Zn(II)/Ox/HM ternary and the Zn(II)/HN and Zn(II)/HM binary systems at [Zn(II)(aq)]tot>4 mM. In contrast, Zn(II) uptake for the Zn(II)/HM binary system is a factor of 2 greater than that for the Zn(II)/Ox/HM and Zn(II)/Ox/HN ternary systems and the Zn(II)/HN binary system at [Zn(II)(aq)]totternary system at both R values examined (0.16 and 0.68), attenuated total reflectance Fourier transform infrared (ATR-FTIR) results are consistent with the presence of inner-sphere oxalate complexes and outer-sphere ZnOx(aq) complexes, and/or type A ternary complexes. In addition, extended X-ray absorption fine structure (EXAFS) spectroscopic results suggest that type A ternary surface complexes (i.e., >O2-Zn-Ox) are present. In the Zn(II)/Ox/HN ternary system at R=0.15, ATR-FTIR results indicate the presence of inner-sphere oxalate and outer-sphere ZnOx(aq) complexes; the EXAFS results provide no evidence for inner-sphere Zn(II) complexes or type A ternary complexes. In contrast, ATR-FTIR results for the Zn/Ox/HN sample with R = 0.68 are consistent with a ZnOx(s)-like surface precipitate and possibly type B ternary surface complexes (i.e., >O2-Ox-Zn). EXAFS results are also consistent with the presence of ZnOx(s)-like precipitates. We ascribe the observed increase of Zn(II)(aq) uptake in the Zn(II)/Ox/HN ternary system at [Zn(II)(aq)]tot>or=4 mM relative to the Zn(II)/Ox/HM ternary system to formation of a ZnOx(s)-like precipitate at the hematite nanoparticle/water interface.

    2006-01-01

    The Digital Mammography Imaging Screening Trial (DMIST), conducted under the auspices of the American College of Radiology Imaging Network (ACRIN), is a clinical trial designed to compare the accuracy of digital versus screen-film mammography in a screening population [E. Pisano et al., ACRIN 6652--Digital vs. Screen-Film Mammography, ACRIN (2001)]. Part I of this work described the Quality Control program developed to ensure consistency and optimal operation of the digital equipment. For many of the tests, there were no failures during the 24 months imaging was performed in DMIST. When systems failed, they generally did so suddenly rather than through gradual deterioration of performance. In this part, the utility and effectiveness of those tests are considered. This suggests that after verification of proper operation, routine extensive testing would be of minimal value. A recommended set of tests is presented including additional and improved tests, which we believe meet the intent and spirit of the Mammography Quality Standards Act regulations to ensure that full-field digital mammography systems are functioning correctly, and consistently producing mammograms of excellent image quality

    Recent progress especially in the field of gene identification and expression has attracted greater attention to the genetic and epigenetic susceptibility to cancer, possibly enhanced by ionising radiation. This issue is especially important for radiation therapists since hypersensitive patients may suffer from adverse effects in normal tissues following standard radiation therapy, while normally sensitive patients could receive higher doses of radiation, offering a better likelihood of cure for malignant tumours. Although only a small percentage of individuals are ''hypersensitive'' to radiation effects, all medical specialists using ionising radiation should be aware of the aforementioned progress in medical knowledge. The present paper, the second of two parts, reviews human disorders known or strongly suspected to be associated with hypersensitivity to ionising radiation. The main tests capable of detecting such pathologies in advance are analysed, and ethical issues regarding genetic testing are considered. The implications for radiation protection of possible hypersensitivity to radiation in a part of the population are discussed, and some guidelines for nuclear medicine professionals are proposed.

    Using photon correlation spectroscopy, transmission electron microscopy, microcalorimetry, wide-angle X-ray scattering (WAXS), and small-angle X-ray and neutron scattering (SAXS, SANS), the structure of 1,2-dimyristoyl-sn-glycero-3-phosphocholine (DMPC)-stabilized colloidal tetracosane suspensions was studied from the molecular level to the microscopic scale as a function of the temperature. The platelike nanocrystals exhibit for tetracosane an unusual orthorhombic low-temperature crystal structure. The corresponding WAXS pattern can be reproduced with a predicted orthorhombic unit cell (space group Pca21), which usually occurs only for much longer even-numbered n-alkanes. Special emphasis was placed on the structure of the DMPC stabilizer layer covering the nanocrystals. Their structure was investigated by SAXS and SANS, using suspensions with different neutron scattering contrasts. As for the emulsions in Part I , the crystallized nanoparticles are covered by a DMPC monolayer. Their significant smaller thickness of 10.5 Å (for the emulsions in Part I : 16 Å) could be related to a more tilted orientation of the DMPC molecules to cover the expanded surface of the crystallized nanoparticles.

    In this work, the friction anisotropy of hexagonal MoS(2) (a well-known lamellar compound) was theoretically investigated. A molecular dynamics method was adopted to study the dynamical friction of two-layered MoS(2) sheets at atomistic level. Rotational disorder was depicted by rotating one layer and was changed from 0° to 60°, in 5° intervals. The superimposed structures with misfit angle of 0° and 60° are commensurate, and others are incommensurate. Friction dynamics was simulated by applying an external pressure and a sliding speed to the model. During friction simulation, the incommensurate structures showed extremely low friction due to cancellation of the atomic force in the sliding direction, leading to smooth motion. On the other hand, in commensurate situations, all the atoms in the sliding part were overcoming the atoms in counterpart at the same time while the atomic forces were acted in the same direction, leading to 100 times larger friction than incommensurate situation. Thus, lubrication by MoS(2) strongly depended on its interlayer contacts in the atomic scale. According to part I of this paper [Onodera, T., et al. J. Phys. Chem. B 2009, 113, 16526-16536], interlayer sliding was source of friction reduction by MoS(2) and was originally derived by its material property (interlayer Coulombic interaction). In addition to this interlayer sliding, the rotational disorder was also important to achieve low friction state.

    The sea anemone venom contains pore-forming proteins (PFP) named actinoporins, due to their purification from organisms belonging to Actiniaria order and its ability to form pores in sphingomyelin-containing membranes. Actinoporins are generally basic, monomeric and single-domain small proteins (∼20 kDa) that are classified as α-type PFP since the pore formation in membranes occur through α-helical elements. Different actinoporin isoforms have been isolated from most of the anemones species, as was analyzed in the first part of this review. Several actinoporin full-length genes have been identified from genomic-DNA libraries or messenger RNA. Since the actinoporins lack carbohydrates and disulfide bridges, their expression in bacterial systems is suitable. The actinoporins heterologous expression in Escherichia coli simplifies their production, replaces the natural source reducing the ecological damage in anemone populations, and allows the production of site-specific mutants for the study of the structure-function relationship. In this second part of the review, the strategies for heterologous production of actinoporins in Escherichia coli are analyzed, as well as the different approaches used for their purification. The activity of the recombinant proteins with respect to the wild-type is also reviewed. Copyright © 2016 Elsevier Ltd. All rights reserved.

    2008-01-01

    Full Text Available This article is the second in a two-part series reviewing the empirical evidence for complementary and alternative medicine (CAM approaches for the management of pain related to medical procedures in infants up to 6 weeks of age. Part I of this series investigated the effects of sucrose with or without non-nutritive sucking (NNS. The present article examines other CAM interventions for procedural pain including music-based interventions, olfactory stimulation, kangaroo care and swaddling. Computerized databases were searched for relevant studies including prior reviews and primary trials. Preliminary support was revealed for the analgesic effects of the CAM modalities reviewed. However, the overall quality of the evidence for these approaches remains relatively weak. Additional well-designed trials incorporating rigorous methodology are required. Such investigations will assist in the development of evidence-based guidelines on the use of CAM interventions either alone or in concert with conventional approaches to provide safe, reliable analgesia for infant procedural pain.

    This paper is an overview of the current Euratom FP-7 research and training actions in innovative nuclear fission reactors and fuel cycle technologies, including partitioning and transmutation. It is based on the more than 40 invited lectures that were delivered by research project coordinators and by keynote speakers at the FISA-2009 Conference, organised by the European Commission DG Research/Euratom. The education and training programmes in nuclear fission and radiation protection are also discussed, aiming at continuously increasing the level of nuclear competences across the EU. It is necessary to consider the most recent nuclear fission technologies (Generations of Nuclear Power Plants): - GEN II: safety and reliability of nuclear facilities and energy independence; - GEN III: continuous improvement of safety and reliability, and increased industrial competitiveness in a growing energy market; - GEN IV: for increased sustainability, and proliferation resistance. The focus in this paper is on the design objectives and research issues associated to Generations IV systems that have been agreed upon internationally. Their benefits are discussed according to a series of ambitious criteria or technology goals established at the international level. One will have to produce not only electricity at lower costs but also heat at very high temperatures, while exploiting a maximum of fissile and fertile matters, and recycling all actinides, under safe and reliable conditions. Scientific viability studies and technological performance tests for each Generation IV system are now being carried out in many laboratories world-wide, in line with the intergovernmental GIF agreement. The ultimate phase of commercial deployment is foreseen for 2040. (orig.)

  10. The evolution of the temperature field during cavity collapse in liquid nitromethane. Part II: reactive case

    This work is concerned with the effect of cavity collapse in non-ideal explosives as a means of controlling their sensitivity. The main objective is to understand the origin of localised temperature peaks (hot spots) which play a leading order role at the early stages of ignition. To this end, we perform two- and three-dimensional numerical simulations of shock-induced single gas-cavity collapse in liquid nitromethane. Ignition is the result of a complex interplay between fluid dynamics and exothermic chemical reaction. In the first part of this work, we focused on the hydrodynamic effects in the collapse process by switching off the reaction terms in the mathematical formulation. In this part, we reinstate the reactive terms and study the collapse of the cavity in the presence of chemical reactions. By using a multi-phase formulation which overcomes current challenges of cavity collapse modelling in reactive media, we account for the large density difference across the material interface without generating spurious temperature peaks, thus allowing the use of a temperature-based reaction rate law. The mathematical and physical models are validated against experimental and analytic data. In Part I, we demonstrated that, compared to experiments, the generated hot spots have a more complex topological structure and that additional hot spots arise in regions away from the cavity centreline. Here, we extend this by identifying which of the previously determined high-temperature regions in fact lead to ignition and comment on the reactive strength and reaction growth rate in the distinct hot spots. We demonstrate and quantify the sensitisation of nitromethane by the collapse of the isolated cavity by comparing the ignition times of nitromethane due to cavity collapse and the ignition time of the neat material. The ignition in both the centreline hot spots and the hot spots generated by Mach stems occurs in less than half the ignition time of the neat material. We compare

    In the first part of this paper, a model describing photopolymer materials, which incorporates both the physical electromagnetic and photochemical effects taking place, was developed. This model is now validated by applying it to fit experimental data for two different types of photopolymer materials. The first photopolymer material, acrylamide/polyvinyl alcohol, is studied when four photosensitizers are used, i.e. Erythrosine B, Eosin Y, Phloxine B and Rose Bengal. The second type of photopolymer material involves phenanthrenequinone in a polymethylmethacrylate matrix. Using our model, the values of physical parameters, are extracted by numerical fitting experimentally obtained normalized transmittance growth curves. Experimental data sets for different exposure intensities, dye concentrations, and exposure geometries are studied. The advantages of our approach are demonstrated and it is shown that the parameters proposed by us to quantify the absorptive behavior in our model are both physical and can be estimated.

    Strategies for approaching generational issues that affect teaching and learning, mentoring, and technology in emergency medicine (EM) have been reported. Tactics to address generational influences involving the structure and function of the academic emergency department (ED), organizational culture, and EM schedule have not been published. Through a review of the literature and consensus by modified Delphi methodology of the Society for Academic Emergency Medicine Aging and Generational Issues Task Force, the authors have developed this two-part series to address generational issues present in academic EM. Understanding generational characteristics and mitigating strategies can address some common issues encountered in academic EM. By understanding the differences and strengths of each of the cohorts in academic EM departments and considering simple mitigating strategies, faculty leaders can maximize their cooperative effectiveness and face the challenges of a new millennium. © 2011 by the Society for Academic Emergency Medicine.

    Full Text Available The second part of the article describes the technology of marine engine diagnostics making use of dynamic measurements of the exhaust gas temperature. Little-known achievements of Prof. S. Rutkowski of the Naval College in Gdynia (now: Polish Naval Academy in this area are presented. A novel approach is proposed which consists in the use of the measured exhaust gas temperature dynamics for qualitative and quantitative assessment of the enthalpy flux of successive pressure pulses of the exhaust gas supplying the marine engine turbocompressor. General design assumptions are presented for the measuring and diagnostic system which makes use of a sheathed thermocouple installed in the engine exhaust gas manifold. The corrected thermal inertia of the thermocouple enables to reproduce a real time-history of exhaust gas temperature changes.

    The objective of this work is the numerical study of an industrial process of energy storage which consists in the use of a cylindrical tank filled with encapsulated phase change materials (PCM). A particularity is present in this kind of processes; it concerns the delay of the crystallization of the PCM, called supercooling phenomenon. The development of the model for cold storage with heat transfer fluid flowing enables a detailed analysis of this process. The effects of different parameters on the behaviour of the tank, such as the inlet temperature, the flow rate, are examined when the tank is in vertical position. There is substantial agreement between the prediction and the experimental values already presented in part I. (author)

    The organisation, administration and running of a successful OSCE programme need considerable knowledge, experience and planning. Different teams looking after various aspects of OSCE need to work collaboratively for an effective question bank development, examiner training and standardised patients' training. Quality assurance is an ongoing process taking place throughout the OSCE cycle. In order for the OSCE to generate reliable results it is essential to pay attention to each and every element of quality assurance, as poorly standardised patients, untrained examiners, poor quality questions and inappropriate scoring rubrics each will affect the reliability of the OSCE. The validity will also be influenced if the questions are not realistic and mapped against the learning outcomes of the teaching programme. This part of the Guide addresses all these important issues in order to help the reader setup and quality assure their new or existing OSCE programmes.

    This second, and concluding, part of this study evaluated changes in sampling efficiency of respirable size-selective samplers due to air pulsations generated by the selected personal sampling pumps characterized in Part I (Lee E, Lee L, Möhlmann C et al. Evaluation of pump pulsation in respirable size-selective sampling: Part I. Pulsation measurements. Ann Occup Hyg 2013). Nine particle sizes of monodisperse ammonium fluorescein (from 1 to 9 μm mass median aerodynamic diameter) were generated individually by a vibrating orifice aerosol generator from dilute solutions of fluorescein in aqueous ammonia and then injected into an environmental chamber. To collect these particles, 10-mm nylon cyclones, also known as Dorr-Oliver (DO) cyclones, were used with five medium volumetric flow rate pumps. Those were the Apex IS, HFS513, GilAir5, Elite5, and Basic5 pumps, which were found in Part I to generate pulsations of 5% (the lowest), 25%, 30%, 56%, and 70% (the highest), respectively. GK2.69 cyclones were used with the Legacy [pump pulsation (PP) = 15%] and Elite12 (PP = 41%) pumps for collection at high flows. The DO cyclone was also used to evaluate changes in sampling efficiency due to pulse shape. The HFS513 pump, which generates a more complex pulse shape, was compared to a single sine wave fluctuation generated by a piston. The luminescent intensity of the fluorescein extracted from each sample was measured with a luminescence spectrometer. Sampling efficiencies were obtained by dividing the intensity of the fluorescein extracted from the filter placed in a cyclone with the intensity obtained from the filter used with a sharp-edged reference sampler. Then, sampling efficiency curves were generated using a sigmoid function with three parameters and each sampling efficiency curve was compared to that of the reference cyclone by constructing bias maps. In general, no change in sampling efficiency (bias under ±10%) was observed until pulsations exceeded 25% for the

    This paper focuses on potential hazards and risks to forensic anthropologists while working in the field and laboratory in North America. Much has changed since Galloway and Snodgrass published their seminal article addressing these issues. The increased number of forensic practitioners combined with new information about potential hazards calls for an updated review of these pathogens and chemicals. Discussion of pathogen hazards (Brucella, Borrelia burgdorferi, Yersinia pestis, Clostridium tetani and West Nile virus) includes important history, exposure routes, environmental survivability, early symptoms, treatments with corresponding morbidity and mortality rates, and decontamination measures. Additionally, data pertaining to the use of formaldehyde in the laboratory environment have resulted in updated safety regulations, and these are highlighted. These data should inform field and laboratory protocols. The hazards of working directly with human remains are discussed in a companion article, "An Update on the Hazards and Risks of Forensic Anthropology, Part I: Human Remains." © 2015 American Academy of Forensic Sciences.

    In the second part of this talk, we investigate the mechanisms that enable energy exchange between semiconductor quantum dots (QDs) and two-dimensional (2D) materials. First, we study possible contributions due to multiple mechanisms such as charge transfer, metallic screening, mechanical strain, and Forster resonant energy transfer (FRET). By implementing different 2D materials (graphene, MoS2, hexagonal boron nitride), varying their thickness and QD emission wavelengths we demonstrate that QD fluorescence quenching is dominated by FRET. Next, we study the dependence of the FRET rate on electrostatic doping of 2D materials, focusing on the case of monolayer MoS2. We develop a simple model, which shows that that moderate (QD photoluminescence intensity. Finally, we demonstrate that FRET can be used as an efficient spectroscopic tool that probes states in 2D materials that are not accessible via conventional absorption spectroscopy.

    Hotel room cleanliness is based on observation and not on microbial assessment even though recent reports suggest that infections may be acquired while staying in hotel rooms. Exploratory research in the first part of the authors' study was conducted to determine if contamination of hotel rooms occurs and whether visual assessments are accurate indicators of hotel room cleanliness. Data suggested the presence of microbial contamination that was not reflective of visual assessments. Unfortunately, no standards exist for interpreting microbiological data and other indicators of cleanliness in hotel rooms. The purpose of the second half of the authors' study was to examine cleanliness standards in other industries to see if they might suggest standards in hotels. Results of the authors' study indicate that standards from other related industries do not provide analogous criteria, but do provide suggestions for further research.

    In the second part of this review on the deep mycoses, we describe the main systemic mycoses-paracoccidioidomycosis, coccidioidomycosis, histoplasmosis, mucormycosis, and cryptococcosis-and their cutaneous manifestations. Skin lesions are only occasionally seen in deep systemic mycoses either directly, when the skin is the route of entry for the fungus, or indirectly, when the infection has spread from a deeper focus. These cutaneous signs are often the only clue to the presence of a potentially fatal infection. As with the subcutaneous mycoses, early diagnosis and treatment is important, but in this case, even more so. Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U. All rights reserved.

    1997-01-01

    Purpose: The purpose of this course is to familiarize radiation oncologists with the concepts and terminology of molecular and cellular biology that are especially relevant to radiation oncology. The ability of radiation oncologists to remain current with the new discoveries of modern biology is essential to the development of improved therapeutic strategies and, importantly, to the proper balance between investment in technology and biology. Objective: This year, this Refresher Course is part of a three-part ''series'' including Drs. McKenna and Dritschilo. The objective is to provide continuing education for the academic and practicing radiation oncologist, physicist and biologist in the modern biologic concepts of cancer and its treatment. An effort will be made to relate these general concepts to the clinic by providing a broad view as to potential new biological treatments which might enhance the efficacy of radiation therapy. The specific focus of this Course will vary from year to year. Some of the classic radiation biology models which form the basis of clinical practice and laboratory research will be examined and 'newer' models will be presented which take into account the emerging knowledge of cellular and molecular biology. A few techniques in molecular and cellular biology will be described to the extent necessary to understand their basic concepts and their applicability. Aspects of radiation biology which will be covered include cell cycle, radiation-induced changes in the cellular phenotype, and considerations of the effect of the tumor microenvironment. It is not the expectation that the attendees will become experts in the particular subjects presented. Rather, it is the intent to increase their curiosity as to the new knowledge that is emerging and to demonstrate that these seemingly complicated areas can be understood and appreciated with a modicum of the effort

    2017-08-01

    A stable partitioned algorithm is developed for fluid-structure interaction (FSI) problems involving viscous incompressible flow and rigid bodies. This added-mass partitioned (AMP) algorithm remains stable, without sub-iterations, for light and even zero mass rigid bodies when added-mass and viscous added-damping effects are large. The scheme is based on a generalized Robin interface condition for the fluid pressure that includes terms involving the linear acceleration and angular acceleration of the rigid body. Added mass effects are handled in the Robin condition by inclusion of a boundary integral term that depends on the pressure. Added-damping effects due to the viscous shear forces on the body are treated by inclusion of added-damping tensors that are derived through a linearization of the integrals defining the force and torque. Added-damping effects may be important at low Reynolds number, or, for example, in the case of a rotating cylinder or rotating sphere when the rotational moments of inertia are small. In this second part of a two-part series, the general formulation of the AMP scheme is presented including the form of the AMP interface conditions and added-damping tensors for general geometries. A fully second-order accurate implementation of the AMP scheme is developed in two dimensions based on a fractional-step method for the incompressible Navier-Stokes equations using finite difference methods and overlapping grids to handle the moving geometry. The numerical scheme is verified on a number of difficult benchmark problems.

    The Ankylos endosseous dental implant is a new implant design that will be available in the United States in early 2004. It features an internal tapered abutment connection, a smooth polished collar without threads at the coronal part of the implant body, and a roughened surface with variable threads on the body of the implant fixture. A precise, tapered, conical abutment connection eliminates the microgap often found in 2-stage implant systems. This microgap may allow the accumulation of food debris and bacteria, as well as micromovement between the parts during clinical function, both of which can lead to a localized inflammation and crestal bone loss. The purpose of this section of the study was to assess any crestal bone loss associated with this new implant. The clinical performance of this new implant design was studied under well-controlled clinical conditions. Over 1500 implants were placed and restored. The vertical crestal bone loss was measured "directly" between the time of implant placement and uncovering, using a periodontal probe. Serial dental radiographs were taken between loading, and the 12-, 24-, and 36-month follow-up visits to determine "indirect" crestal bone loss within a specific period. Bone loss varied among the participating centers from less than 0.5 mm to 2.0 mm. The largest amount of bone loss occurred between the time of placement and uncovering. Following loading, the mean bone loss for all implants for a period of 3 years was about 0.2 mm/y. The extent of the crestal bone loss after loading was minimal for patients regardless of age, gender, prosthetic applications, bone density, and remote or crestal incisions, as well as for smokers or nonsmokers. Bone loss per year is well within the guidelines of 0.2 mm/y proposed by others.

    The development of an ink dating method requires an important investment of resources in order to step from the monitoring of ink ageing on paper to the determination of the actual age of a questioned ink entry. This article aimed at developing and evaluating the potential of three interpretation models to date ink entries in a legal perspective: (1) the threshold model comparing analytical results to tabulated values in order to determine the maximal possible age of an ink entry, (2) the trend tests that focusing on the "ageing status" of an ink entry, and (3) the likelihood ratio calculation comparing the probabilities to observe the results under at least two alternative hypotheses. This is the first report showing ink dating interpretation results on a ballpoint be ink reference population. In the first part of this paper three ageing parameters were selected as promising from the population of 25 ink entries aged during 4 to 304days: the quantity of phenoxyethanol (PE), the difference between the PE quantities contained in a naturally aged sample and an artificially aged sample (R NORM ) and the solvent loss ratio (R%). In the current part, each model was tested using the three selected ageing parameters. Results showed that threshold definition remains a simple model easily applicable in practice, but that the risk of false positive cannot be completely avoided without reducing significantly the feasibility of the ink dating approaches. The trend tests from the literature showed unreliable results and an alternative had to be developed yielding encouraging results. The likelihood ratio calculation introduced a degree of certainty to the ink dating conclusion in comparison to the threshold approach. The proposed model remains quite simple to apply in practice, but should be further developed in order to yield reliable results in practice.

    Full Text Available This study was started to find alternative binders to bentonite and to recover the low preheated and fired pellet mechanical strengths of organic binders-bonded pellets. Bentonite is considered as a chemical impurity for pellet chemistry due to acid constituents (SiO2 and Al2O3. Especially addition of silica-alumina bearing binders is detrimental for iron ore concentrate with high acidic content. Organic binders are the most studied binders since they are free in silica. Although they yield pellets with good wet strength; they have found limited application in industry since they fail to give sufficient physical and mechanical strength to preheated and fired pellets. It is investigated that how insufficient preheated and fired pellet strengths can be improved when organic binders are used as binder. The addition of a slag bonding/strength increasing constituent (free in acidic contents into pellet feed to provide pellet strength with the use of organic binders was proposed. Addition of boron compounds such as colemanite, tincal, borax pentahydrate, boric acid together with organic binders such as CMC, starch, dextrin and some organic based binders, into magnetite and hematite pellet mixture was tested. After determining the addition of boron compounds is beneficial to recover the low pellet physical and mechanical qualities in the first part of this study, in this second part, metallurgical and chemical properties (reducibility - swelling index – microstructure – mineralogy - chemical content of pellets produced with combined binders (an organic binder plus a boron compound were presented. The metallurgical and chemical tests results showed that good quality product pellets can be produced with combined binders when compared with the bentonite-bonded pellets. Hence, the suggested combined binders can be used as binder in place of bentonite in iron ore pelletizing without compromising the pellet chemistry.

    HIV infection leads to a gradual loss CD4(+) T lymphocytes comprising immune competence and progression to AIDS. Effective treatment with combined antiretroviral drugs (cART) decreases viral load below detectable levels but is not able to eliminate the virus from the body. The success of cART is frustrated by the requirement of expensive lifelong adherence, accumulating drug toxicities and chronic immune activation resulting in increased risk of several non-AIDS disorders, even when viral replication is suppressed. Therefore, there is a strong need for therapeutic strategies as an alternative to cART. Immunotherapy, or therapeutic vaccination, aims to increase existing immune responses against HIV or induce de novo immune responses. These immune responses should provide a functional cure by controlling viral replication and preventing disease progression in the absence of cART. The key difficulty in the development of an HIV vaccine is our ignorance of the immune responses that control of viral replication, and thus how these responses can be elicited and how they can be monitored. Part one of this review provides an extensive overview of the (patho-) physiology of HIV infection. It describes the structure and replication cycle of HIV, the epidemiology and pathogenesis of HIV infection and the innate and adaptive immune responses against HIV. Part two of this review discusses therapeutic options for HIV. Prevention modalities and antiretroviral therapy are briefly touched upon, after which an extensive overview on vaccination strategies for HIV is provided, including the choice of immunogens and delivery strategies.

    Marine hydrokinetic energy is a promising and growing piece of the renewable energy sector that offers high predictability and additional energy sources for a diversified energy economy. This report investigates the market opportunities for tidal energy along the U.S. coastlines. It is part one of a two-part investigation into the United States' two largest marine hydrokinetic resources (wave and tidal). Tidal energy technology is still an emerging form of renewable energy for which large-scale grid-connected project costs are currently poorly defined. Ideally, device designers would like to know the resource conditions at economical project sites so they can optimize device designs. On the other hand, project developers need detailed device cost data to identify sites where projects are economical. That is, device design and siting are, to some extent, a coupled problem. This work describes a methodology for identifying likely deployment locations based on a set of criteria that tidal energy experts in industry, academia, and national laboratories agree are likely to be important factors for all technology types. Several factors that will affect tidal project costs and siting have not been considered here -- including permitting constraints, conflicting use, seasonal resource variability, extreme event likelihood, and distance to ports -- because consistent data are unavailable or technology-independent scoring could not be identified. As the industry continues to mature and converge around a subset of device archetypes with well-defined costs, more precise investigations of project siting that include these factors will be possible. For now, these results provide a high-level guide pointing to the regions where markets and resource will one day support commercial tidal energy projects.

    The first part of this paper gives a detailed account of the evaluation of the electric dipole amplitude induced in alkali one-photon S-S transitions, by the parity violating electron-nucleus short range potential associated with the weak neutral currents. Two methods are presented: the first involves an explicit sum over the contributions of the P-states admixed with the S-states and incorporates the best information available on S-P electric dipole amplitudes. The second method, mathematically more elegant, avoids with the help of Green's function techniques any explicit sum over the P states, and, provided that some spin-orbit corrections are neglected, leads to a fairly simple formula involving Coulomb integrals tabulated in the literature and the interpolated quantum defects for S and P waves. The second part is devoted to a description of possible ways to detect parity violation induced in radiative S-S transitions, with a brief discussion of physical processes which could be a source of experimental difficulty. The last section of the paper deals with a theoretical analysis of the influence of a static electric field on the radiative S-S transitions. An evaluation of the induced electric dipole amplitude in the case of cesium indicates that it will compete with the magnetic dipole amplitude for electric fields larger than 10 V/cm. An interference effect between these two amplitudes gives rise to an electronic polarization in the final atomic state proportional to the vector product of the static electric field by the photon momentum which, in a typical case, could be as large as 64%; the measurement of this interesting and rather peculiar effect will lead to a determination of the sign of the magnetic dipole amplitude. Moreaver parity violation could manifest itself by a dependence of this electron polarization on the state of circular polarization of the incident photon [fr

  19. The Narrative Reproduction of Contemporary Montenegrin Identity in The Process of Euroatlantic Intergrations (Part II

    Branko Banović

    2016-02-01

    Full Text Available If we conceptualize reality as a large narrative we “build ourselves into” as social beings, and consider social activities and identities as narratively mediated, the full extent of the capacity of narratives in the creation, shaping, transmission and reconstruction of contemporary social identities, as well as the reproduction of the concept of nation in everyday life becomes apparent. The imagined Euro- Atlantic future of Montenegro demands certain narrative interpretations of the past, which, in latter stages tend to become meta-narratives susceptible to consensus. The linkage of significant historical events to the process of Euro-Atlantic integrations of Montenegro is preformed through different meta-discursive practices, most often through ceremonial evocations of memories of significant events from the recent as well as further history of Montenegro. In this context, celebrations of Statehood Day and Independence Day are especially important, as they serve as reminders of the decisions of the Congress of Berlin, the Podgorica Assembly, the antifascist struggle of World War II and the independence of Montenegro attained through the referendum held in 2006. The clearly defined key points, along with the logical coherence the narrative is based on, provide the narrative with a certain “flexibility” which enables it to take in new elements. Narrative interpretations of the past have a significant role in the reproduction of the nation, as well as the shaping and consolidation of a desirable national identity, while the established narrative continuity between the past, present and imagined Euro-Atlantic future of Montenegro emerges as the “official” mediator in the reproduction of contemporary Montenegrin identity in the process of Euro-Atlantic integrations. In order to fully comprehend this narrative, it is advisable to conceptualize it both in a synchronic as well as a diachronic perspective, as can be shown in two charts
