    Full Text Available

    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.

Debido a la mayor frecuencia de este tipo de infecciones en los pacientes quemados, pretendemos identificar qué factores influyen en la presentación y predicción de la infección intrahospitalaria en el sitio de la quemadura (IISQ. El presente estudio es una cohorte retrospectiva, sobre 298 registros de expedientes clínicos de pacientes ingresados en la Unidad Nacional de Quemados del Hospital San Juan de Dios (UNQ-HSJD en Costa Rica, continuando otra investigación del mismo grupo de autores publicada anteriormente en Cirugía Plástica Iberolatinoamericana. A cada factor de riesgo estudiado se le calcularon los odds ratio crudos en un análisis univariado definiendo como variables de exposición principal la superficie corporal total quemada (SCTQ y la profundidad de la quemadura (PQ. Observamos con este cálculo que el tipo de accidente no presentaba asociación con la IISQ. Después, realizamos un modelo multivariado logístico, no condicional, en el que se introdujeron los siguientes factores de riesgo: SCTQ, PQ, edad, número de segmentos corporales quemados (NSCQ, días de estancia hospitalaria previos a la infección intrahospitalaria en el sitio de la quemadura (DEHP-IISQ y el agente causal de la quemadura.

    Full Text Available El objetivo de este artículo es reflexionar críticamente, a partir de una selección de últimos informes, investigaciones, publicaciones y otras fuentes, sobre las orientaciones de cómo «empoderar» a los y las menores frente a los riesgos on-line actuales. Entre los diferentes riesgos quisiéramos destacar los que más violencia emocional producen; las situaciones de «grooming» o ciberacoso, cada vez más visibles y urgentes de prevenir conjuntamente. El uso de Internet y la facilidad de visibilizar cualquier información o situación ha permitido romper el tabú social respecto a estos riesgos. Datos como el que el 44% de menores en España se había sentido acosado sexualmente en Internet en alguna ocasión en el 2002, o el que el 20% de niños en Estados Unidos sufría ciberacoso, según una encuesta realizada a 4.400 estudiantes en el 2010, nos indican la gravedad de la problemática. Por ello, tal y como se recoge en el Currículum MIL de la UNESCO para profesores (Media and Information Literacy, es necesario trabajar el uso responsable de Internet por parte de los y las menores, para empoderarlos evitando que puedan convertirse en futuras víctimas o acosadores. A partir de los riesgos reales que pueden padecer, así como las respuestas científicas y sociales que se han dado al respecto, elaboraremos una serie de recomendaciones a tener en cuenta en el diseño de actividades educativas enfocadas a la capacitación crítica de los y las menores en cuanto su uso de Internet.

    The proper management of your revenue cycle requires the application of "best practices" and the continual monitoring and measuring of the entire cycle. The correct technology will enable you to gain the insight and efficiencies needed in the ever-changing healthcare economy. The revenue cycle is a process that begins when you negotiate payor contracts, set fees, and schedule appointments and continues until claims are paid in full. Every single step in the cycle carries equal importance. Monitoring all phases and a commitment to continually communicating the results will allow you to achieve unparalleled success. In part I of this article, we explored the importance of contracting, scheduling, and case management as well as coding and clinical documentation. We will now take a closer look at the benefits charge capture, claim submission, payment posting, accounts receivable follow-up, and reporting can mean to your practice.

Podemos definir la Enfermedad Profesional como el riesgo a enfermarse en el ejercicio de alguna especialidad o profesión con la patología sui generis (1. Aunque hace alrededor de veinte años se creía que los anestésicos inhalatorios no se metabolizaban, la preocupación por los riesgos inherentes a su toxicidad ha existido casi desde su descubrimiento. Ya en 1893 Hewit (2 notó que la descomposición del cloroformo en ácido clorhídrico y fosgeno por acción del gas de iluminación producía tos, irritación orofaringea y cefalea. En 1903 (2 encontró que el éter cloroformo e hidrato de cloral aumentaba la mortalidad producida por el antrax de los cerdos. En 1922 en Editorial de (3 Anesthesiology se reconoce el efecto deletéreo posible por la exposición repetida de los anestésicos.

    Pharmacoeconomics started as marketing but has developed into a valuable tool in the fuller assessment of drug therapies. Its principles are now widely accepted, and many countries have government-funded agencies with responsibility for its application, most notably the National Institute for Health and Clinical Excellence in England. Many clinical pharmacologists are active in this area, and the discipline itself is part of the clinical pharmacology trainees' curriculum. Further developments will include value-based pricing and its use in cost sharing arrangements between health service and manufacturers.

    Full Text Available The goal of this simulation is to introduce and realize a part of material flow of an international furniture manufacturing company. This simulation was made with a special process-simulation software, called SIMUL8. With SIMUL8 we could simulate the whole process under real circumstances, and obtain the actual values of specific parameters relevant for the company. This opportunity helped the company to develop its strategy - to maximize the production efficiency and to find out the possibble bottle-necks without making any investment, and to rearrange the workcenters effectively.

    Curricular review is considered a necessary component for growth and enhancement of academic programs and requires time, energy, creativity, and persistence from both faculty and administration. On a larger scale, a comprehensive redesign effort involves forming a dedicated faculty redesign team, developing program learning outcomes, mapping the existing curriculum, and reviewing the curriculum in light of collected stakeholder data. The faculty of the Texas A&M University College of Veterinary Medicine & Biomedical Sciences (TAMU) recently embarked on a comprehensive curriculum redesign effort through partnership with the university's Center for Teaching Excellence. Using a previously developed evidence-based model of program redesign, TAMU created a process for use in veterinary medical education, which is described in detail in the first part of this article series. An additional component of the redesign process that is understated, yet vital for success, is faculty buy-in and support. Without faculty engagement, implementation of data-driven curricular changes stemming from program evaluation may be challenging. This second part of the article series describes the methodology for encouraging faculty engagement through the final steps of the redesign initiative and the lessons learned by TAMU through the redesign process.

  7. Anomalous transport from holography: Part II

    CERN Document Server

    Bu, Yanyan; Sharon, Amir

    2016-01-01

    This is a second study of chiral anomaly induced transport within a holographic model consisting of anomalous $U(1)_V\\times U(1)_A$ Maxwell theory in Schwarzschild-$AdS_5$ spacetime. In the first part, chiral magnetic/separation effects (CME/CSE) are considered in presence of a static spatially-inhomogeneous external magnetic field. Gradient corrections to CME/CSE are analytically evaluated up to third order in the derivative expansion. Some of the third order gradient corrections lead to an anomaly-induced negative $B^2$-correction to the diffusion constant. We also find non-linear modifications to the chiral magnetic wave (CMW). In the second part, we focus on the experimentally interesting case of the axial chemical potential being induced dynamically by a constant magnetic and time-dependent electric fields. Constitutive relations for the vector/axial currents are computed employing two different approximations: (a) derivative expansion (up to third order) but fully nonlinear in the external fields, and (...

    Science.gov (United States)

    Payette, Michael; Grant-Kels, Jane M

    2012-03-01

    In part I, we discussed new drug development, reviewed the history of the generic drug industry, described how generic drugs are approved by the US Food and Drug Administration, and defined the concepts of bioequivalence and therapeutic equivalence. Herein, we explore various factors impacting generic drug use across the different parties involved: the prescriber, the pharmacist, the patient, and the payer. We also include original cost analysis of dermatologic brand name and generic drugs and show the potential cost savings that can be achieved through generic substitution. We conclude with a review of the data addressing potential differences in the effectiveness of brand name versus generic drugs in dermatology. The cost of brand name and generic medications is highly variable by pharmacy, state, and payer. We used one source (www.drugstore.com) as an example and for consistency across all medications discussed herein. Prices included here may not reflect actual retail prices across the United States.

    The study of socioeconomic inequality is of prime economic and social importance, and the key quantitative gauges of socioeconomic inequality are Lorenz curves and inequality indices - the most notable of the latter being the popular Gini index. In this series of papers we present a sociogeometric framework to the study of socioeconomic inequality. In this part we focus on the gap between the rich and the poor, which is quantified by gauges termed disparity curves. We shift from disparity curves to disparity sets, define inequality indices in terms of disparity sets, and introduce and explore a collection of distance-based and width-based inequality indices stemming from the geometry of disparity sets. We conclude with mean-absolute-deviation (MAD) representations of the inequality indices established in this series of papers, and with a comparison of these indices to the popular Gini index.

  10. Submodeling Simulations in Fusion Welds: Part II

    Science.gov (United States)

    Bonifaz, E. A.

    2013-11-01

    In part I, three-dimensional transient non-linear sub modeling heat transfer simulations were performed to study the thermal histories and thermal cycles that occur during the welding process at the macro, meso and micro scales. In the present work, the corresponding non-uniform temperature changes were imposed as load conditions on structural calculations to study the evolution of localized plastic strains and residual stresses at these sub-level scales. To reach the goal, a three-dimensional finite element elastic-plastic model (ABAQUS code) was developed. The sub-modeling technique proposed to be used in coupling phase-field (and/or digital microstructures) codes with finite element codes, was used to mesh a local part of the model with a refined mesh based on interpolation of the solution from an initial, relatively coarse, macro global model. The meso-sub-model is the global model for the subsequent micro sub-model. The strategy used to calculate temperatures, strains and residual stresses at the macro, meso and micro scale level, is very flexible to be used to any number of levels. The objective of this research was to initiate the development of microstructural models to identify fusion welding process parameters for preserving the single crystal nature of gas turbine blades during repair procedures. The multi-scale submodeling approach can be used to capture weld pool features at the macro-meso scale level, and micro residual stress and secondary dendrite arm spacing features at the micro scale level.

  11. TEXTILE STRUCTURES FOR AERONAUTICS (PART II

    2014-05-01

    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.

  12. [Conceptual Development in Cognitive Science. Part II].

    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.

  13. Compressor Part II: Volute Flow Predictions

    Directory of Open Access Journals (Sweden)

    Yu-Tai Lee

    1999-01-01

    Full Text Available A numerical method that solves the Reynolds-averaged Navier-Stokes equations is used to study an inefficient component of a shipboard air-conditioning HCFC-124 compressor system. This high-loss component of the centrifugal compressor was identified as the volute through a series of measurements given in Part I of the paper. The predictions were made using three grid topologies. The first grid closes the connection between the cutwater and the discharge diffuser. The other two grids connect the cutwater area with the discharge diffuser. Experiments were performed to simulate both the cutwater conditions used in the predictions. Surface pressures along the outer wall and near the inlet of the volute were surveyed for comparisons with the predictions. Good agreements between the predicted results and the measurements validate the calculations. Total pressure distributions and flow stream traces from the prediction results support the loss distribution through the volute. A modified volute configuration is examined numerically for further loss comparison.

    Apart from some questions related to the repairability of resin composite restorations, dentists have always assumed that methacrylate-based resins are compatible with each other. For example, there is no clinically relevant problem in using a microfilled composite to laminate a Class IV restoration made with a hybrid composite, even if they are not of the same brand or manufacturer. In the context of adhesive systems, we have always believed that resin composites, regardless of their type or composition, bond well to all types of bonding agents. However, unexpected debonding of self-cured, core buildup composites that had been bonded with single-bottle adhesive systems was reported about 5 years ago. Subsequent studies demonstrated that there were, indeed, compatibility problems between simplified adhesive systems and self- or dual-cured resin composites. Apparently, when such combinations are used, reduced bond strengths and subsequent failures at the resin-adhesive interface can occur because of adverse reactions between the acidic resin monomers, an integral part of the simplified adhesive systems, and the chemicals involved in the polymerization mechanism of the self- or dual-cured composites, particularly the basic tertiary amines.

    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.

  11. High gradient magnetic filtration and separation. Part II

    Energy Technology Data Exchange (ETDEWEB)

    Fletcher, D.

    The paper contains the second part of a two part paper in which the developing role of high grade magnetic filtration and separation (HGMF/S) is reviewed. Part I discussed the increasing potential for the technique and outlined the basic theory behind it. Part II describes the practical application of the technique with particular reference to the beneficiation of fine coal. Aspects considered are: a simple laboratory HGMF/S device; the matrix and its efficency; processing rates in HGMF/S; coal desulphurization and deashing - a potential application of HGMS. The paper concludes that HGMF/S is a process of high potential application as natural particles have a wide variation of magnetic character. Add to this the space saving nature of very powerful superconducting systems and their low energy consumption and it can be safely predicted that HGMF/S will, over time, gain many more applications as whole or part of whole filtration and separation processes. 19 references.

    Although image interpretation is an essential part of radiologists' value, there are other ways in which we contribute to patient care. Part II of the value of imaging series reviews current initiatives that demonstrate value beyond the image interpretation. Standardizing processes, reducing the radiation dose of our examinations, clarifying written reports, improving communications with patients and providers, and promoting appropriate imaging through decision support are all ways we can provide safer, more consistent, and higher quality care. As payers and policy makers push to drive value, research that demonstrates the value of these endeavors, or lack thereof, will become increasingly sought after and supported.

  1. “Sexo inseguro”: un análisis de la racionalidad como parte del riesgo entre jóvenes caleños y caleñas.

    Directory of Open Access Journals (Sweden)

    Teresita María Sevilla Peñuela

    2008-05-01

    Full Text Available El artículo se enmarca en el debate en torno al concepto de riesgo que se da desde las ciencias sociales y humanas entre la denominada corriente realista –que tiende a asumir que las conductas que implican riesgo son irracionales y que aquellas que lo evitan son producto de la racionalidad– y la posición que, desde el constructivismo social, apunta a interpretar la toma de riesgo no como un hecho aislado e irracional sino como respuesta a lógicas complejas y particulares del contexto sociocultural en que se genera dicha decisión. Apoyando la última posición, este texto elabora parte de los resultados de un estudio doctoral en sociología, de corte etnográfico, entre jóvenes caleños y caleñas para (1 caracterizar las lógicas de racionalidad que sustentan ciertas prácticas en torno a la sexualidad, a la luz de factores como género y estrato socio-económico, y (2 analizar la concepción del riesgo más allá de su tradicional acepción negativa, para explorar las posibles funciones y valoraciones positivas asignadas por los sujetos en coherencia con su entorno socio-cultural. A partir de las nociones de análisis de género (en sus dimensiones de relacionalidad, historicidad y estructuras de poder y de estrato socio-económico (asumido como una categoría que supera los aspectos estrictamente económicos, se ha podido identificar que elementos como la valoración positiva del no uso del condón, las diferencias de género en la elección de la pareja sexual y los beneficios que representa tener un hijo o una hija a temprana edad, entre otros, juegan un papel fundamental en los procesos de negociación del riesgo. En este sentido, se argumenta que las conductas de riesgo están insertas en densos entramados de significación de fuerte vinculación a lo social y contextual.

    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.

    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.

    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.

    PREREM is an interactive computer code developed as a data preprocessor for the INREM-II (Killough, Dunning, and Pleasant, 1978a) internal dose program. PREREM is intended to provide easy access to current and self-consistent nuclear decay and radionuclide-specific metabolic data sets. Provision is made for revision of metabolic data, and the code is intended for both production and research applications. Documentation for the code is in two parts. Part I is a user's manual which emphasizes interpretation of program prompts and choice of user input. Part II stresses internal structure and flow of program control and is intended to assist the researcher who wishes to revise or modify the code or add to its capabilities. PREREM is written for execution on a Digital Equipment Corporation PDP-10 System and much of the code will require revision before it can be run on other machines. The source program length is 950 lines (116 blocks) and computer core required for execution is 212 K bytes. The user must also have sufficient file space for metabolic and S-factor data sets. Further, 64 100 K byte blocks of computer storage space are required for the nuclear decay data file. Computer storage space must also be available for any output files produced during the PREREM execution. 9 refs., 8 tabs.

    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

    The Part I of Primer of Statistics in Dental Research covered five topics that are often mentioned in statistical check list of many peer-review journals including (1) statistical graph, (2) how to deal with outliers, (3) p-value and confidence interval, (4) testing equivalence, and (5) multiplicity Adjustment. The Part II of the series covers another set of important topics in dental statistics including (1) selecting the proper statistical tests, (2) repeated measures analysis, (3) epidemiological consideration for causal association, and (4) analysis of agreement. First, a guide in selecting the proper statistical tests based on the research question will be laid out in text and with a table so that researchers choose the univariable statistical test by answering five simple questions. Second, the importance of utilizing repeated measures analysis will be illustrated. This is a key component of data analysis as in many dental studies, observations are considered repeated in a single patient (several teeth are measured in a single patient). Third, concepts of confounding and the use of regression analysis are explained by going over a famous observational cohort study. Lastly, the use of proper agreement analysis vs. correlation for study of agreement will be discussed to avoid a common pitfall in dental research.

  17. Hypoelastic Soft Tissues: Part II: In-Plane Biaxial Experiments.

    Science.gov (United States)

    Freed, Alan D; Einstein, Daniel R; Sacks, Michael S

    2010-08-01

    In Part I, a novel hypoelastic framework for soft-tissues was presented. One of the hallmarks of this new theory is that the well-known exponential behavior of soft-tissues arises consistently and spontaneously from the integration of a rate based formulation. In Part II, we examine the application of this framework to the problem of biaxial kinematics, which are common in experimental soft-tissue characterization. We confine our attention to an isotropic formulation in order to highlight the distinction between non-linearity and anisotropy. In order to provide a sound foundation for the membrane extension of our earlier hypoelastic framework, the kinematics and kinetics of in-plane biaxial extension are revisited, and some enhancements are provided. Specifically, the conventional stress-to-traction mapping for this boundary value problem is shown to violate the conservation of angular momentum. In response, we provide a corrected mapping. In addition, a novel means for applying loads to in-plane biaxial experiments is proposed. An isotropic, isochoric, hypoelastic, constitutive model is applied to an in-plane biaxial experiment done on glutaraldehyde treated bovine pericardium. The experiment is comprised of eight protocols that radially probe the biaxial plane. Considering its simplicity (two adjustable parameters) the model does a reasonably good job of describing the non-linear normal responses observed in these experimental data, which are more prevalent than are the anisotropic responses exhibited by this tissue.

  18. Bedside ultrasonography-Applications in critical care: Part II

    Directory of Open Access Journals (Sweden)

    2014-01-01

    Full Text Available Point of care ultrasonography, performed by acute care physicians, has developed into an invaluable bedside tool providing important clinical information with a major impact on patient care. In Part II of this narrative review, we describe ultrasound guided central venous cannulation, which has become standard of care with internal jugular vein cannulation. Besides improving success rates, real-time guidance also significantly reduces the incidence of complications. We also discuss compression ultrasonography - a quick and effective bedside screening tool for deep vein thrombosis of the lower extremity. Abdominal ultrasound offers vital clues in the emergency setting; in the unstable trauma victim, a focused examination may provide immediate answers and has largely superseded diagnostic peritoneal lavage in diagnosing intraperitoneal bleed. From estimation of intracranial pressure to transcranial Doppler studies, ultrasound is becoming increasingly relevant to neurocritical care. Ultrasound may also help with airway management in several situations, including percutaneous tracheostomy. Clearly, bedside ultrasonography has become an indispensable part of intensive care practice - in the rapid assessment of critically ill-patients as well as in enhancing the safety of invasive procedures.

  19. Reforming Science Education: Part II. Utilizing Kieran Egan's Educational Metatheory

    Science.gov (United States)

    Schulz, Roland M.

    2009-04-01

    This paper is the second of two parts and continues the conversation which had called for a shift in the conceptual focus of science education towards philosophy of education, with the requirement to develop a discipline-specific “philosophy” of science education. In Part I, conflicting conceptions of science literacy were identified with disparate “visions” tied to competing research programs as well as school-based curricular paradigms. The impasse in the goals of science education and thereto, the contending views of science literacy, were themselves associated with three underlying fundamental aims of education (knowledge-itself; personal development; socialization) which, it was argued, usually undercut the potential of each other. During periods of “crisis-talk” and throughout science educational history these three aims have repeatedly attempted to assert themselves. The inability of science education research to affect long-term change in classrooms was correlated not only to the failure to reach a consensus on the aims (due to competing programs and to the educational ideologies of their social groups), but especially to the failure of developing true educational theories (largely neglected since Hirst). Such theories, especially metatheories, could serve to reinforce science education’s growing sense of academic autonomy and independence from socio-economic demands. In Part II, I offer as a suggestion Egan’s cultural-linguistic theory as a metatheory to help resolve the impasse. I hope to make reformers familiar with his important ideas in general, and more specifically, to show how they can complement HPS rationales and reinforce the work of those researchers who have emphasized the value of narrative in learning science.

  20. Diagnosis of occlusal caries: Part II. Recent diagnostic technologies.

    Tam, L E; McComb, D

    2001-09-01

    Accurate diagnosis of the presence or absence of disease is a fundamental requirement in health care. The diagnosis of non-overt occlusal decay is challenging and can be highly subjective, and its inherent uncertainties can lead to widely differing treatment decisions. The purpose of this 2-part paper is to review current knowledge concerning conventional and new diagnostic methods for occlusal caries. Part I looked at established methods for diagnosing occlusal decay. These methods have several limitations, particularly in their ability to diagnose early carious lesions. Part II examines new and emerging technologies that are being developed for the diagnosis of occlusal decay. Electrical conductance measurements and quantitative laser- or light-induced fluorescence represent significant improvements over conventional diagnostic methods, especially for in vitro applications and particularly with regard to sensitivity and reproducibility. Proponents of the DIAGNOdent laser fluorescence system claim that it evaluates the fluorescence that develops when laser light is incident on areas of demineralization. This noninvasive device is simple to use and provides quantitative data. Studies supporting its validity are limited but do suggest good sensitivity and excellent reproducibility. However, the DIAGNOdent system requires more scientific scrutiny. Although it offers a high rate of disease detection, it has little ability to indicate the extent of decay. In all treatment decisions, clinicians must be aware of the limitations of the diagnostic methods that have been used. Clinical judgment based on the patient s case history, visual cues, review of radiographs and probability of disease is still the most important aspect of optimum patient care. New technologies may provide supplemental information, but they cannot yet replace established methods for the diagnosis of occlusal caries.

  2. Repeated-sprint ability - part II: recommendations for training.

    Bishop, David; Girard, Olivier; Mendez-Villanueva, Alberto

    2011-09-01

    Short-duration sprints, interspersed with brief recoveries, are common during most team sports. The ability to produce the best possible average sprint performance over a series of sprints (≤10 seconds), separated by short (≤60 seconds) recovery periods has been termed repeated-sprint ability (RSA). RSA is therefore an important fitness requirement of team-sport athletes, and it is important to better understand training strategies that can improve this fitness component. Surprisingly, however, there has been little research about the best training methods to improve RSA. In the absence of strong scientific evidence, two principal training theories have emerged. One is based on the concept of training specificity and maintains that the best way to train RSA is to perform repeated sprints. The second proposes that training interventions that target the main factors limiting RSA may be a more effective approach. The aim of this review (Part II) is to critically analyse training strategies to improve both RSA and the underlying factors responsible for fatigue during repeated sprints (see Part I of the preceding companion article). This review has highlighted that there is not one type of training that can be recommended to best improve RSA and all of the factors believed to be responsible for performance decrements during repeated-sprint tasks. This is not surprising, as RSA is a complex fitness component that depends on both metabolic (e.g. oxidative capacity, phosphocreatine recovery and H+ buffering) and neural factors (e.g. muscle activation and recruitment strategies) among others. While different training strategies can be used in order to improve each of these potential limiting factors, and in turn RSA, two key recommendations emerge from this review; it is important to include (i) some training to improve single-sprint performance (e.g. 'traditional' sprint training and strength/power training); and (ii) some high-intensity (80-90% maximal oxygen

  4. Part 3: Pharmacogenetic Variability in Phase II Anticancer Drug Metabolism

    Science.gov (United States)

    Deenen, Maarten J.; Cats, Annemieke; Beijnen, Jos H.

    2011-01-01

    Equivalent drug doses may lead to wide interpatient variability in drug response to anticancer therapy. Known determinants that may affect the pharmacological response to a drug are, among others, nongenetic factors, including age, gender, use of comedication, and liver and renal function. Nonetheless, these covariates do not explain all the observed interpatient variability. Differences in genetic constitution among patients have been identified to be important factors that contribute to differences in drug response. Because genetic polymorphism may affect the expression and activity of proteins encoded, it is a key covariate that is responsible for variability in drug metabolism, drug transport, and pharmacodynamic drug effects. We present a series of four reviews about pharmacogenetic variability. This third part in the series of reviews is focused on genetic variability in phase II drug-metabolizing enzymes (glutathione S-transferases, uridine diphosphoglucuronosyl transferases, methyltransferases, sulfotransferases, and N-acetyltransferases) and discusses the effects of genetic polymorphism within the genes encoding these enzymes on anticancer drug therapy outcome. Based on the literature reviewed, opportunities for patient-tailored anticancer therapy are proposed. PMID:21659608

    New technologies that facilitate solid alveolar ridge augmentation are receiving considerable attention in the field of prosthodontics because of the growing requirement for esthetic and functional reconstruction by dental implant treatments. Recently, several studies have demonstrated potential advantages for stem-cell-based therapies in regenerative treatments. Mesenchymal stem/stromal cells (MSCs) are now an excellent candidate for tissue replacement therapies, and tissue engineering approaches and chair-side cellular grafting approaches using autologous MSCs represent the clinical state of the art for stem-cell-based alveolar bone regeneration. Basic studies have revealed that crosstalk between implanted donor cells and recipient immune cells plays a key role in determining clinical success that may involve the recently observed immunomodulatory properties of MSCs. Part II of this review first overviews progress in regenerative dentistry to consider the implications of the stem cell technology in dentistry and then highlights cutting-edge stem-cell-based alveolar bone regenerative therapies. Factors that affect stem-cell-based bone regeneration as related to the local immune response are then discussed. Additionally, pre-clinical stem cell studies for the regeneration of teeth and other oral organs as well as possible applications of MSC-based immunotherapy in dentistry are outlined. Finally, the marketing of stem cell technology in dental stem cell banks with a view toward future regenerative therapies is introduced. Copyright © 2012 Japan Prosthodontic Society.

    The IPCC (as opposed to the UN Framework Convention) defines climate change as" any change in climate over time, whether due to natural variability or as a result of human activity". The IPCC Working Group II (Impacts, Adaptation, Vulnerability) was charged with assessing the scientific, technical, environmental, economic, and social aspects of vulnerability to climate change, and, the negative and positive consequences for ecological systems, socio-economic sectors, and human health. The Working Group II report focused on the following issues for different sectors and regions (e.g. water, agriculture, biodiversity) and communities (coastal, island, etc.): · The role of adaptation in reducing vulnerability and impacts, · Assessment of adaptation capacity, options and constraints, and · Enhancing adaptation practice and operations. This presentation will address the following questions in the context of the results of the IPCC Fourth Assessment Report WG II: · What are the barriers, knowledge gaps, and opportunities for impacts assessments? · How are decisions about adaptation being made, and what types of adaptation strategies are being undertaken? · What are good adaptation practices and how are they learned over time? Examples will be drawn from the freshwater resources, small islands and adaptation chapters to which the presenter contributed. Many lessons have been identified but few have been implemented or evaluated over time. Adaptation occurs in the context of multiple stresses. Adaptation will be important in coping with early impacts in the near-term and continue to be important as our climate changes, regardless of how that change is derived. It is important to note that unmitigated climate change could, in the long term, exceed the capacity of different natural, managed and human systems to adapt. The assessment leads to the following conclusions: · Adaptation to climate change is already taking place, but on a limited basis · Adaptation measures

    Full Text Available A copper-selective electrode of the coated wire type based on sulphidized copper wire was applied successfully for determining Cu(II ions by complexometric titration with the disodium salt of EDTA (complexon III. By the formation of internal complex compounds with the Cu(II ion, the copper concentration in the solution decreases, and all this is followed by a change of potential of the indicator system Cu-DWISE (or Cu-EDWISE/SCE. At the terminal point of titration, when all the Cu(II ions are already utilized for the formation of the complex with EDTA, there occurs a steep rise of potential, thus enabling us, through the first or second derivative to note the quantity of copper that is present in the solution. Copper-selective electrode showed a responsivity towards titration with EDTA as a complexing agent, with the absence of "fatigue" due to a great number of repeated measurings. Errors occurring during quantitative measurements were more a characteristic of the overall procedure which involve, because of the impossibility of the complete absence of subjectivity, a constant error, and the reproducibility of the results confirmed this fact. The disodium salt of EDTA appeared as a very efficient titrant in all titrations and with various concentrations ot Cu(II ions in the solution, with somewhat weaker response at lower concentrations in the solution.

    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.

    Although several biological agents have been recognized as presenting a significant threat to public health if used in a bioterrorist attack, those that are of greatest importance are known as the Category A agents: Bacillus anthracis (anthrax); variola major (smallpox); Yersinia pestis (plague); Francisella tularensis (tularemia); ribonucleic acid viruses (hemorrhagic fevers); and Clostridium botulinum (botulism toxin). In the previous issue, Part I of this review focused on the clinical presentation and treatment of anthrax, plague, and tularemia. In this second part of this 2-part review of these agents, the focus is on the clinical presentation and treatment of smallpox, viral hemorrhagic fevers, and botulism toxin. The utilization of mass prophylaxis to limit the morbidity and mortality associated with all these agents is also discussed along with the role emergency care personnel play in its implementation.

    The literature directly and indirectly related to centric relation (CR) has been reviewed chronologically. More than 300 papers and quoted sections of books have been divided into three sections. The first two parts of the paper are related to CR. Studies in this group mainly compared either the position of the mandibular condyle or the mandible itself in different CR recordings. Various tools were discussed for this purpose. The third part deals with CR-centric occlusion (CO) discrepancy. CR remains one of the controversial issues in prosthodontics and orthodontics. Debates relating to mounting casts on the articulator by reproducible records for orthodontic treatment planning and end results, and whether or not orthodontic treatment based on CO causes temporomandibular joint (TMJ) dysfunction, remain unsolved.

    The conformational potential energy surface paths of the sex pheromone, Ipsenol, to the Bark Beetle, Ips typographus, and of a series of analogues have been elucidated using the program DAISY. The following structures were calculated: 2-methyl-6-methylene-7-octen-4-ol (Ipsenol, ( II)), 2-methyl-6-methylene-2,7-octadiene-4-ol acetate ( III), 2-methyl-6-methylene-3,7-octadien-2-ol ( IV), 2-methyl-6-methylene-1,7-octadien-3-ol ( V), 5-(3-furanyl)-2-methyl-1-penten-3-ol ( VI) and 1-(3-furanyl)-4-methyl-3-penten-2-ol ( VII). As a measure of the conformational flexibility of the molecules the flexibility coefficients, f, were determined. The f values for the molecules were determined to be: II, 0.145; III, 0.144; IV, 1.240; V, 0.133; VI, 0.825; and VII, 0.451. The molecular mechanics method was used for energy calculations in conjunction with DAISY. Low-energy conformations (conformational channels) together with energy barriers for conformational changes are presented.

    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...

    In the first part of the article, a new algorithm for pruning network?Dynamic Optimal Brain Damage(DOBD) is introduced. In this part, two cases and an industrial application are worked out to test the new algorithm. It is verified that the algorithm can obtain good generalization through deleting weight parameters with low sensitivities dynamically and get better result than the Marquardt algorithm or the cross-validation method. Although the initial construction of network may be different, the finial number of free weights pruned by the DOBD algorithm is similar and the number is just close to the optimal number of free weights. The algorithm is also helpful to design the optimal structure of network.

A 424 (1999) 26-33] detector characteristics, such as quantum efficiency, detective quantum efficiency, sensitivity to neutron- and gamma-radiation, readout time and dynamic range are predicted. It is estimated that quantum efficiencies and detective quantum efficiencies close to 100% can be reached making these kind of detectors interesting for a wide range of applications.

  1. A tutorial survey of topics in wireless networking: Part II

    2007-12-01

    This is the second part of the survey of recent and emerging topics in wireless networking. We provide an overview of the area of wireless networking as that of dealing with problems of resource allocation so that the various connections that utilise the network achieve their desired performance objectives. In Part I we provided a taxonomy of wireless networks as they have been deployed. We then provided a quick survey of the main issues in the wireless 'physical' layer. We then discussed some resource allocation formulations in CDMA (code division multiple access) cellular networks and OFDMA (orthogonal frequency division multiple access) networks. In this part we begin with a discussion of random access wireless networks. We first provide an overview of the evolution of random access networks from Aloha to the currently popular 802·11 (Wi-Fi) networks. We then analyse the performance of the 802·11 random access protocol. We briefly discuss the problem of optimal association of nodes to Wi-Fi access points. Next, we consider topics in ad hoc multihop wireless networks. We first discuss topology and cross layer control. For the latter, we describe the important maximum weight link scheduling algorithm. The connectivity and capacity of randomly deployed networks are then analysed. Finally, we provide an overview of the technical issues in the emerging area of wireless sensor networks.

    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.

    Full Text Available The two-world background of the Special Theory of Relativity started in part one of this article is continued in this second part. Four-dimensional inversion is shown to be a special Lorentz transformation that transforms the positive spacetime coordinates of a frame of reference in the positive universe into the negative spacetime coordinates of the symmetry-partner frame of reference in the negative universe in the two-world picture, contrary to the conclusion that four-dimensional inversion is impossible as actual trans- formation of the coordinates of a frame of reference in the existing one-world picture. By starting with the negative spacetime dimensions in the negative universe derived in part one, the signs of mass and other physical parameters and physical constants in the negative universe are derived by application of the symmetry of laws between the pos- itive and negative universes. The invariance of natural laws in the negative universe is demonstrated. The derived negative sign of mass in the negative universe is a conclu- sion of over a century-old effort towards the development of the concept of negative mass in physics.

    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.

    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.

  13. The Symmetric Group Defies Strong Fourier Sampling: Part II

    Moore, Cristopher; Moore, Cristopher; Russell, Alexander

    2005-01-01

    Part I of this paper showed that the hidden subgroup problem over the symmetric group--including the special case relevant to Graph Isomorphism--cannot be efficiently solved by strong Fourier sampling, even if one may perform an arbitrary POVM on the coset state. In this paper, we extend these results to entangled measurements. Specifically, we show that the hidden subgroup problem on the symmetric group cannot be solved by any POVM applied to pairs of cosets states. In particular, these hidden subgroups cannot be determined by any polynomial number of one- or two-register experiments on coset states.

    Combining elastic and inelastic processes with transfer reactions, this two-part volume explores how these events affect heavy ion collisions. Special attention is given to processes involving the transfer of two nucleons, which are specific for probing pairing correlations in nuclei. This novel treatment provides, together with the description of surface vibration and rotations, a unified picture of heavy ion reactions in terms of the elementary modes of nuclear excitation. Heavy Ion Reactions is essential reading for beginning graduate students as well as experienced researchers.

    Clinical assessment of a child with Tourette's syndrome (TS) includes a careful review of motor and phonic tics. In addition, commonly associated problems of such as obsessive-compulsive symptoms, or symptoms of attention deficit hyperactivity disorder (inattention, impulsiveness, and overactivity) should also be evaluated. Treatment almost always includes education of the child, family, and school personnel concerning the natural history and behavioral boundaries of the disorder. Other treatment interventions depend to a great extent on the primary source of impairment. This article, the second of two parts, presents three illustrative cases and reviews current treatment interventions for children and adolescents with TS.

    Full Text Available Due to the failure of manganese aluminium bronze (MAB propeller caused by dealloying corrosion as described in Part I [1], this work aims to study the prevention of dealloying corrosion using aluminium and zinc sacrificial anodes. The results indicated that both of the sacrificial anodes could prevent the propeller from dealloying. Moreover, the dealloying in seawater was less than that found in brackish water. It was possible that hydroxide ions, from cathodic reaction, reacted with calcium in seawater to form calcium carbonate film protecting the propeller from corrosion.

    2012-03-01

    Full Text Available This paper compares the simulation and initial experimental results for robust part handling by radially symmetric cylindrical electromagnetic gripper heads, that are used in foundry manufacturing assembly operation. Knowledge of the direct holding force is essential to determine if a given electromagnet is capable of preventing part slipping during pick and place operation. Energy based model and the magnetic circuit model have been described. The latter is developed further and compared with results from a FEA software. It was found that the magnetic circuit model, although simple in form, was limited in its ability to accurately predict the holding force over the entire range of conditions investigated. The shortcomings in the model were attributed to its inability to accurately model the leakage flux and non-uniform distribution of the magnetic flux. A finite element allowed for the ability to couple the mechanical and magnetic models. The finite element model was used to predict the magnetic field based off the solutions to the mechanical (sigma and the magnetic model (B.

    Active flow control is applied to a NACA-0012 profile. The experiments are conducted in a wind tunnel. Using a high-resolution visible-light camera and tomography, flow visualizations are carried out. LES finite-volume 3D code is used to complement the physical experiments. The symmetric wing is clipped into two parts, and those parts extend and retract along the chord according to the same sinusoidal law we optimized last year for the same profile but clipped at an angle of 60 deg, instead of the original 90 deg. The Reynolds number range is extended to 500,000, thus covering the flying regimes of micro-UAVs, UAVs, as well as small aircraft. When the nascent cavity is open and the attack angle is 30 deg, the drag coefficient is increased by 1,300%, as compared to the uncontrolled case. However, when the cavity is covered and Re <=105 , a relatively small frequency, f <= 30 Hz, is required for the drag coefficient to drop to negative values. At the maximum Reynolds number, thrust is generated but only at much higher frequencies, 12 <= f <= 16 kHz.

    2015-02-01

    2014 was a year of continued high activity in the pharma and biotech industry, as evidenced in part I of this annual two-part review article published last month in this journal (1). As of December 23, 2014, a total of 55 new chemical and biological entities had reached their first markets worldwide, together with another 29 important new line extensions. Another 19 products were approved for the first time during the year but not yet launched by December 23. Furthermore, during the now-traditional year-end sprint, several regulatory agencies issued last-minute approvals for other compounds that missed the deadline for inclusion in that article, bringing the total of new approvals for the year to a somewhat higher number. In addition to the successful development, registration and launch of new drugs and biologics, there are various other trends and tendencies that serve as indicators of the overall health and status of the industry. These include the pursuit of novel programs designed by regulators to stimulate the development of drugs for diseases that are currently under-treated; the regular and pragmatic culling by companies of their R&D pipelines; and the decision to unify pipelines, portfolios and sales forces through mergers and acquisitions.

    2004-07-01

    A collagenolytic or necrobiotic non-infectious granuloma is one in which a granulomatous infiltrate develops around a central area of altered collagen and elastic fibers. The altered fibers lose their distinct boundaries and exhibit new staining patterns, becoming either more basophilic or eosinophilic. Within the area of altered collagen, there may be deposition of acellular substances such as mucin (blue) or fibrin (red), or there may be neutrophils with nuclear dust (blue), eosinophils (red), or flame figures (red). These color distinctions can be used as a simple algorithm for the diagnosis of collagenolytic granulomas, i.e. 'blue' granulomas vs. 'red' granulomas. Eight diagnoses are included within these two groupings, which are discussed in this two-part article. In the previously published first part, the clinical presentation, pathogenesis and histologic features of the 'blue' collagenolytic granulomas were discussed. These are the lesions of granuloma annulare, Wegener's granulomatosis, and rheumatoid vasculitis. In this second half of the series, the 'red' collagenolytic granulomas are discussed; these are the lesions of necrobiosis lipoidica, necrobiotic xanthogranuloma, rheumatoid nodules, Churg-Strauss syndrome, and eosinophilic cellulitis (Well's Syndrome).

    Recent studies on the spreading phenomena of liquid dispersions of nanoparticles (nanofluids) have revealed that the self-layering and two-dimensional structuring of nanoparticles in the three-phase contact region exert structural disjoining pressure, which drives the spreading of nanofluids by forming a continuous wedge film between the liquid (e.g., oil) and solid surface. Motivated by the practical applications of the phenomenon and experimental results reported in Part I of this two-part series, we thoroughly investigated the spreading dynamics of nanofluids against an oil drop on a solid surface. With the Laplace equation as a starting point, the spreading process is modeled by Navier-Stokes equations through the lubrication approach, which considers the structural disjoining pressure, gravity, and van der Waals force. The temporal interface profile and advancing inner contact line velocity of nanofluidic films are analyzed through varying the effective nanoparticle concentration, the outer contact angle, the effective nanoparticle size, and capillary pressure. It is found that a fast and spontaneous advance of the inner contact line movement can be obtained by increasing the nanoparticle concentration, decreasing the nanoparticle size, and/or decreasing the interfacial tension. Once the nanofluidic film is formed, the advancing inner contact line movement reaches a constant velocity, which is independent of the outer contact angle if the interfacial tension is held constant.

    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.

    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.

    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.

    Responsive biomaterial hydrogels attract significant attention due to their biocompatibility and degradability. In order to make chitosan based gels, we first graft one layer of chitosan to silica, and then build a chitosan/poly(acrylic acid) multilayer using the layer-by-layer approach. After...... cross-linking the chitosan present in the polyelectrolyte multilayer, poly(acrylic acid) is partly removed by exposing the multilayer structure to a concentrated carbonate buffer solution at a high pH, leaving a surface-grafted cross-linked gel. Chemical cross-linking enhances the gel stability against......-linking density. The amount of poly(acrylic acid) trapped inside the surface grafted films was found to decrease with decreasing cross-linking density, as confirmed in situ using TIRR, and ex situ by Fourier transform infrared (FTIR) measurements on dried films. The responsiveness of the chitosan-based gels...

    2009-08-01

    In this paper we exploit a formalism to describe edge radiation, which relies on Fourier optics techniques [G. Geloni, V. Kocharyan, E. Saldin, E. Schneidmiller, M. Yurkov, Theory of edge radiation. Part I: foundations and basic applications, submitted for publication]. First, we apply our method to develop an analytical model to describe edge radiation in the presence of a vacuum chamber. Such model is based on the solution of the field equation with a tensor Green's function technique. In particular, explicit calculations for a circular vacuum chamber are reported. Second, we consider the use of edge radiation as a tool for electron-beam diagnostics. We discuss coherent edge radiation, extraction of edge radiation by a mirror, and other issues becoming important at high electron energy and long radiation wavelength. Based on this work we also study the impact of edge radiation on X-ray Free-Electron Laser (XFEL) setups and we discuss recent results.

    The paper presents the radial distributions of the pressure measured with a Pitot tube for the case of a radial jet with/without swirling of the input flow in the pre-chamber; the length of the supersonic part of the jet, dependency of the jet thickness as a function of the distance from the nozzle outlet, and approximating analytical formula for the jet thickness that generalizes the experimental data. Experimental data demonstrated that at the deposition distances lower than 4-6 gauges from the nozzle outlet, the solid particle velocity and temperature are almost uniform over the jet cross section. This means that the target surface can be allocated here without loss in coating quality and deposition coefficient. The maximal recommended distance where the deposition is still possible is the length of l s0 ~ 16 gauges.

    Newton, MA. A recent report indicated air quality samples taken from several rooms in the town's North High School had elevated CO2 levels of 2,000 parts per million (ppm) (Viser, 2004). State standards set 800 ppm as the optimum reading. Although not an immediate health issue, high CO2 levels are indicative of poor air circulation--clean air comes in but stale air is not vented out. Safety issues arise in the school setting when chemicals or toxic substances are in use and cannot be vented, therefore posing the health risk (Viser, 2004). Poor Indoor Air Quality (IAQ) in schools can result in decreased academic performance and days lost due to illness in the school age population (Environmental Protection Agency [EPA], 2003). As the school nurse at North High School, what would you do?

    2010-01-01

    The availability of positional information is of great importance in many commercial, governmental, and military applications. Localization is commonly accomplished through the use of radio communication between mobile devices (agents) and fixed infrastructure (anchors). However, precise determination of agent positions is a challenging task, especially in harsh environments due to radio blockage or limited anchor deployment. In these situations, cooperation among agents can significantly improve localization accuracy and reduce localization outage probabilities. A general framework of analyzing the fundamental limits of wideband localization has been developed in Part I of the paper. Here, we build on this framework and establish the fundamental limits of wideband cooperative location-aware networks. Our analysis is based on the waveforms received at the nodes, in conjunction with Fisher information inequality. We provide a geometrical interpretation of equivalent Fisher information for cooperative networks....

    2014-01-01

    Eponyms serve the purpose of honoring individuals who have made important observations and discoveries. As with other fields of medicine, eponyms are frequently encountered in radiology, particularly in chest radiology. However, inappropriate use of an eponym may lead to potentially dangerous miscommunication. Moreover, an eponym may honor the incorrect person or a person who falls into disrepute. Despite their limitations, eponyms are still widespread in the medical literature. Furthermore, in some circumstances, more than one individual may have contributed to the description or discovery of a particular anatomical structure or disease, whereas in others, an eponym may have been incorrectly applied initially and propagated for years in the medical literature. Nevertheless, radiologic eponyms are a means of honoring those who have made lasting contributions to the field of radiology, and familiarity with these eponyms is critical for proper reporting and accurate communication. In addition, the acquisition of some historical knowledge about those whose names are associated with various structures or pathologic conditions conveys a sense of humanity in the science of medicine. In this second part of a multipart series, the authors discuss a number of chest radiology eponyms as they relate to the pulmonary vasculature, including relevant clinical and imaging features, as well biographic information of the respective eponym׳s namesake.

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

    Directory of Open Access Journals (Sweden)

    Iwona Sudoł-Szopińska

    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.

    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.

  3. Cyclopentane combustion. Part II. Ignition delay measurements and mechanism validation

    Rachidi, Mariam El

    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 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.

    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.

  6. Stochastic dynamics of Arctic sea ice Part II: Multiplicative noise

    2015-01-01

    We analyze the numerical solutions of a stochastic Arctic sea ice model with multiplicative noise over a wide range of external heat-fluxes, $\\Delta F_0$, which correspond to greenhouse gas forcing. When the noise is multiplicative, the noise-magnitude depends on the state-variable, and this will influence the statistical moments in a manner that differs from the additive case, which we analyzed in Part I of this study. The state variable describing the deterministic backbone of our model is the energy, $E(t)$, contained in the ice or the ocean and for a thorough comparison and contrast we choose the simplest form of multiplicative noise $\\sigma E(t) \\xi(t)$, where $\\sigma$ is the noise amplitude and $\\xi(t)$ is the noise process. The case of constant additive noise (CA) we write as $\\sigma\\overline{E_S}\\xi(t)$, in which $\\overline{E_S}$ is the seasonally averaged value of the periodic deterministic steady-state solution $E_S(t)$, or the deterministic seasonal cycle. We then treat the case of seasonally-varyi...

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.

    2015-01-01

    In the early seventies, Alan Sandage defined cosmology as the search for two numbers: Hubble parameter ${{H}_{0}}$ and deceleration parameter ${{q}_{0}}$. The first of the two basic cosmological parameters (the Hubble parameter) describes the linear part of the time dependence of the scale factor. Treating the Universe as a dynamical system it is natural to assume that it is non-linear: indeed, linearity is nothing more than approximation, while non-linearity represents the generic case. It is evident that future models of the Universe must take into account different aspects of its evolution. As soon as the scale factor is the only dynamical variable, the quantities which determine its time dependence must be essentially present in all aspects of the Universe' evolution. Basic characteristics of the cosmological evolution, both static and dynamical, can be expressed in terms of the parameters ${{H}_{0}}$ and ${{q}_{0}}$. The very parameters (and higher time derivatives of the scale factor) enable us to const...

    2014-07-29

    Responsive biomaterial hydrogels attract significant attention due to their biocompatibility and degradability. In order to make chitosan based gels, we first graft one layer of chitosan to silica, and then build a chitosan/poly(acrylic acid) multilayer using the layer-by-layer approach. After cross-linking the chitosan present in the polyelectrolyte multilayer, poly(acrylic acid) is partly removed by exposing the multilayer structure to a concentrated carbonate buffer solution at a high pH, leaving a surface-grafted cross-linked gel. Chemical cross-linking enhances the gel stability against detachment and decomposition. The chemical reaction between gluteraldehyde, the cross-linking agent, and chitosan was followed in situ using total internal reflection Raman (TIRR) spectroscopy, which provided a molecular insight into the complex reaction mechanism, as well as the means to quantify the cross-linking density. The amount of poly(acrylic acid) trapped inside the surface grafted films was found to decrease with decreasing cross-linking density, as confirmed in situ using TIRR, and ex situ by Fourier transform infrared (FTIR) measurements on dried films. The responsiveness of the chitosan-based gels with respect to pH changes was probed by quartz crystal microbalance with dissipation (QCM-D) and TIRR. Highly cross-linked gels show a small and fully reversible behavior when the solution pH is switched between pH 2.7 and 5.7. In contrast, low cross-linked gels are more responsive to pH changes, but the response is fully reversible only after the first exposure to the acidic solution, once an internal restructuring of the gel has taken place. Two distinct pKa's for both chitosan and poly(acrylic acid), were determined for the cross-linked structure using TIRR. They are associated with populations of chargeable groups displaying either a bulk like dissociation behavior or forming ionic complexes inside the hydrogel film.

  12. Overactive bladder – 18 years – Part II

    Full Text Available 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.

    The evaluation of renewable energy used to increase the environmental friendliness of passive houses (PH) is the topic of this paper. A time-dependent model of passive house thermal behavior is developed. The heat transfer through the high thermal inertia elements is analyzed by using a one-dimensional time-dependent conduction heat-transfer equation that is solved numerically by using a standard Netlib solver (PDECHEB). Appropriate models for the conduction through the low thermal inertia elements are used, as well as a simple approach of the solar radiation transmission through the windows. The model takes into account in a detailed fashion the internal heat sources. Also, the operation of ventilation/heating system is described and common-practice control strategies are implemented. Three renewable energy sources are considered. First, there is the passive solar heating due to the large window on the facade oriented south. Second, the active solar collector system provides thermal energy for space heating or domestic hot water preparation. Third, a ground heat exchanger (GHE) increases the fresh air temperature during the cold season. The model was applied to the Pirmasens Passive House (Rhineland Palatinate, Germany). The passive solar heating system provides most part of the heating energy during November, December, February and March while in January the ground heat exchanger is the most important renewable energy source. January and February require use of additional conventional energy sources. A clever use of the active solar heating system could avoid consuming classical fuels during November, December and March. The ground heat exchanger is a reliable renewable source of energy. It provides heat during all the day and its (rather small) heat flux is increasing when the weather becomes colder. The air temperature at heater exit is normally lower than 46 {sup o}C. This is a good reason for the use of renewable energy to replace the classical fuel or the

    An extreme learning machine (ELM) can be regarded as a two-stage feed-forward neural network (FNN) learning system that randomly assigns the connections with and within hidden neurons in the first stage and tunes the connections with output neurons in the second stage. Therefore, ELM training is essentially a linear learning problem, which significantly reduces the computational burden. Numerous applications show that such a computation burden reduction does not degrade the generalization capability. It has, however, been open that whether this is true in theory. The aim of this paper is to study the theoretical feasibility of ELM by analyzing the pros and cons of ELM. In the previous part of this topic, we pointed out that via appropriately selected activation functions, ELM does not degrade the generalization capability in the sense of expectation. In this paper, we launch the study in a different direction and show that the randomness of ELM also leads to certain negative consequences. On one hand, we find that the randomness causes an additional uncertainty problem of ELM, both in approximation and learning. On the other hand, we theoretically justify that there also exist activation functions such that the corresponding ELM degrades the generalization capability. In particular, we prove that the generalization capability of ELM with Gaussian kernel is essentially worse than that of FNN with Gaussian kernel. To facilitate the use of ELM, we also provide a remedy to such a degradation. We find that the well-developed coefficient regularization technique can essentially improve the generalization capability. The obtained results reveal the essential characteristic of ELM in a certain sense and give theoretical guidance concerning how to use ELM.

    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.

    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). 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. Main results. We found that this system produced responses compatible with the physiological literature. Fusimotor and cortical drives had nonlinear effects on the reflex forces. In particular, only cortical drive affected the sensitivity of reflex forces to static fusimotor drive. In contrast, both static fusimotor and cortical drives reduced the sensitivity to dynamic fusimotor drive. Interestingly, realistic signal-dependent motor noise emerged naturally in our system without having been explicitly modeled. Significance. We demonstrate that these fundamental features of spinal afferentation sufficed to produce muscle function. As such, our Neuro-mechano-morphic system is a viable platform to study the spinal mechanisms for healthy muscle function—and its

    Full Text Available Durante el embarazo, infecciones de diverso tipo pueden poner en riesgo el curso normal del mismo e incluso comprometer la salud del neonato, siendo los partos prematuros, el bajo peso al nacer y la combinación de ambas condiciones, los resultados adversos del embarazo que más frecuentemente se encuentran asociados con las infecciones. La importancia de la asociación de la enfermedad periodontal con los resultados adversos del embarazo se ha ido incrementando en los últimos años. Esta revisión bibliográfica analiza la evidencia científica de distintas publicaciones sobre la relación entre enfermedad periodontal, los partos prematuros y el bajo peso al nacimiento, mostrando que, factores como el diseño de los estudios y los criterios empleados para definir tanto la enfermedad periodontal como los resultados adversos del embarazo, pueden influir sobre los resultados de los estudios. La primera parte de la revisión incluye las aportaciones derivadas de los estudio de casos y controles y de los estudios de cohortes; en esta segunda parte se revisan los ensayos clínicos y las revisiones sistemáticas y metaanálisis.

    Full Text Available Durante los últimos años el crecimiento mundial de catástrofes naturales ha ido en franco aumento. Sin embargo, desde un enfoque sistémico puede verificarse que la gran mayoría de los desastres se origina en los países en desarrollo (entre ellos los latinoamericanos, siendo las pérdidas en ellos significativamente más altas que en los países industrializados. Bajo esta postura los desastres no son sólo naturales sino socio- naturales, enfatizando la estrecha relación de causalidad entre modelos de desarrollo y urbanización y procesos de generación de riesgos, al incrementar la vulnerabilidad de los sectores más desprotegidos. El desastre pone en evidencia así una situación (la pobreza y segregación urbana ya existente, pero no considerada hasta el momento de la catástrofe. Frente a este panorama el desastre aparece como oportunidad que precipita tres catalizadores de políticas habitacionales: tierra, asistencia técnica y financiamiento, incrementando la celeridad y la creatividad de las respuestas. El interrogante que surge es por qué esperar el desastre para ponerlos en marcha, cuando ninguno de ellos es estrictamente dependiente de la situación de riesgo, sino sujeto de luchas de poder.

    2012-09-20

    This is the second of two reviews that is intended to cover the essential aspects of cardiovascular magnetic resonance (CMR) physics in a way that is understandable and relevant to clinicians using CMR in their daily practice. Starting with the basic pulse sequences and contrast mechanisms described in part I, it briefly discusses further approaches to accelerate image acquisition. It then continues by showing in detail how the contrast behaviour of black blood fast spin echo and bright blood cine gradient echo techniques can be modified by adding rf preparation pulses to derive a number of more specialised pulse sequences. The simplest examples described include T2-weighted oedema imaging, fat suppression and myocardial tagging cine pulse sequences. Two further important derivatives of the gradient echo pulse sequence, obtained by adding preparation pulses, are used in combination with the administration of a gadolinium-based contrast agent for myocardial perfusion imaging and the assessment of myocardial tissue viability using a late gadolinium enhancement (LGE) technique. These two imaging techniques are discussed in more detail, outlining the basic principles of each pulse sequence, the practical steps required to achieve the best results in a clinical setting and, in the case of perfusion, explaining some of the factors that influence current approaches to perfusion image analysis. The key principles of contrast-enhanced magnetic resonance angiography (CE-MRA) are also explained in detail, especially focusing on timing of the acquisition following contrast agent bolus administration, and current approaches to achieving time resolved MRA. Alternative MRA techniques that do not require the use of an endogenous contrast agent are summarised, and the specialised pulse sequence used to image the coronary arteries, using respiratory navigator gating, is described in detail. The article concludes by explaining the principle behind phase contrast imaging techniques

    It must be emphasized that none of the steps described in this planning process emerged overnight. Rather, they were achieved through a process of evolution, sometimes through trial and error, and always with consultation and participation by many members of the hospital nursing staff. Participation by many in the process of planning for a workable staffing system has been essential to its success. Indeed, creative scheduling by the head nurse is possible because of the way in which the system has been organized. The fact that head nurses are responsible for staffing their own units makes it infinitely easier for them to see what they need to make their units operate effectively and efficiently. Creative scheduling includes the possibility of arranging nurses' hours outside the rigid three-shift schedule used by so many hospitals. Many El Camino nurses now report for work at different hours. In addition, the use of flexible work weeks has proven valuable. Some head nurses now allow for a ten-hour, four-day work week; in emergency staffing situations there have, on occasion, been twelve-hour days. Even as this system evolves, it faces change. Just as the requirements for staff cannot be rigid, so must problem solving be flexible and constantly under review. The fact that El Camino believes in constant monitoring of its system is essential to its success. A key philosophical foundation of decentralization is that it must be subject to change. This is no less true in staffing than in other parts of the decentralization structure. By agreeing that change is constant and necessary and that participation is required at all levels of the staffing planning process, we have constructed the outlines of a system that will work in the future as well as it does in the present. Our system centers around the head nurses. It involves their planning; thus it also involves the support of those members of the nursing staff who can provide essential information. But the decisions

    2016-07-01

    Synchrotron X-ray tomography (SXRT) has been applied to the study of defects within three-dimensional printed titanium parts. These parts were made using the Arcam EBM(®) (electron beam melting) process which uses powdered titanium alloy, Ti64 (Ti alloy with approximately 6%Al and 4%V) as the feed and an electron beam for the sintering/welding. The experiment was conducted on the Imaging and Medical Beamline of the Australian Synchrotron. The samples represent a selection of complex shapes with a variety of internal morphologies. Inspection via SXRT has revealed a number of defects which may not otherwise have been seen. The location and nature of such defects combined with detailed knowledge of the process conditions can contribute to understanding the interplay between design and manufacturing strategy. This fundamental understanding may subsequently be incorporated into process modelling, prediction of properties and the development of robust methodologies for the production of defect-free parts.

    BACKGROUND: Intravenous infusion of pituitary adenylate cyclase-activating polypeptide-38 (PACAP38) provokes migraine attacks in 65-70% of migraine without aura (MO) patients. We investigated whether PACAP38 infusion causes changes in the endogenous production of PACAP38, vasoactive intestinal...... polypeptide (VIP), calcitonin gene-related peptide (CGRP), tumour necrosis factor alpha (TNFα), S100 calcium binding protein B (S100B), neuron-specific enolase and pituitary hormones in migraine patients. METHODS: We allocated 32 previously genotyped MO patients to receive intravenous infusion PACAP38 (10...... pmol/kg/minute) for 20 minutes and recorded migraine-like attacks. Sixteen of the patients were carriers of the risk allele rs2274316 (MEF2D), which confers increased risk of MO and may regulate PACAP38 expression, and 16 were non-carriers. We collected blood samples at baseline and 20, 30, 40, 60...

    For bulk thermoelectrics, figure-of-merit, ZT, still needs to improve from the current value of 1.0 - 1.5 to above 2 to be competitive to other alternative technologies. In recent years, the most significant improvements in ZT were mainly due to successful reduction of thermal conductivity. However, thermal conductivity cannot be measured directly at high temperatures. The combined measurements of thermal diffusivity and specific heat and density are required. It has been shown that thermal conductivity is the property with the greatest uncertainty and has a direct influence on the accuracy of the figure of merit. The International Energy Agency (IEA) group under the implementing agreement for Advanced Materials for Transportation (AMT) has conducted two international round-robins since 2009. This paper is Part II of the international round-robin testing of transport properties of bulk bismuth telluride. The main focuses in Part II are on thermal diffusivity, specific heat and thermal conductivity.

  10. Partial covering of a circle by equal circles. Part II: The case of 5 circles

    2014-05-01

    Full Text Available How must n equal circles of given radius r be placed so that they cover as great a part of the area of the unit circle as possible? In this Part II of a two-part paper, a conjectured solution of this problem for n = 5 is given for r varying from the maximum packing radius to the minimum covering radius. Results are obtained by applying a mechanical model described in Part I. A generalized tensegrity structure is associated with a maximum area configuration of the 5 circles, and by using catastrophe theory, it is pointed out that the ''equilibrium paths'' have bifurcations, that is, at certain values of r, the type of the tensegrity structure and so the type of the circle configuration changes.

    CERN Document Server

    Pappi, Koralia N; Chronis, Theodore N; Karagiannidis, George K

    2012-01-01

    This is the second part of a two-part series of papers, where the error performance of multidimensional lattice constellations with signal space diversity (SSD) is investigated. In Part I, following a novel combinatorial geometrical approach which is based on parallelotope geometry, we have presented an exact analytical expression and two closed-form bounds for the symbol error probability (SEP) in Additive White Gaussian Noise (AWGN). In the present Part II, we extend the analysis and present a novel analytical expression for the Frame Error Probability (FEP) of multidimensional lattice constellations over Nakagami-m fading channels. As the FEP of infinite lattices is lower bounded by the Sphere Lower Bound (SLB), we propose the Sphere Upper Bound (SUB) for block fading channels. Furthermore, two novel bounds for the FEP of multidimensional lattice constellations over block fading channels, named Multiple Sphere Lower Bound (MSLB) and Multiple Sphere Upper Bound (MSUB), are presented. The expressions for the...

    2001-06-01

    The purpose of this review was to organize a systematic reference to help orthodontists evaluate commonly used orthodontic nickel-titanium alloys. Part I of the article reviewed the data available in the literature regarding the temperature transitional ranges of the alloys. The thermomechanical behavior of these compounds is, in fact, strictly dependent upon the correlation between the temperature transitional range and the oral temperature range. Part II focuses on the mechanical characteristics of the alloys, such as the magnitude of the forces delivered and correlations with the temperature transitional range and oral temperature.

    2013-06-01

    A comprehensive numerical model has been proposed to model thermoelectric generators (TEGs) for automotive waste heat recovery. Details of the model and results from the analysis of General Motors' prototype TEG were described in part I of the study. In part II of this study, parametric evaluations are considered to assess the influence of heat exchanger, geometry, and thermoelectric module configurations to achieve optimization of the baseline model. The computational tool is also adapted to model other topologies such as transverse and circular configurations (hexagonal and cylindrical) maintaining the same volume as the baseline TEG. Performance analysis of these different topologies and parameters is presented and compared with the baseline design.

  14. 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.

  15. Can focusing on UPDRS Part II make assessments of Parkinson disease progression more efficient?

    Science.gov (United States)

    Sampaio, Cristina

    2009-03-01

    Harrison et al. have attempted to validate Part II of the Unified Parkinson's Disease Rating Scale (UPDRS II) as a medication-independent measure of disease progression. The authors collected cross-sectional data from a cohort of 888 patients with idiopathic Parkinson disease, and they found a robust association between UPDRS II scores and disease duration. Other variables considered were the patients' levodopa status, age at disease onset, and scores on UPDRS I, II and III. The results suggest that a single UPDRS II measurement might be a good indicator of progression at a given time point, irrespective of the current disease-related circumstances. This concept is attractive in its simplicity and patient-centeredness. However, this evidence came from a single-center, retrospective study, the statistical model was constructed using a nonvalidated surrogate as an independent variable, and no external replication was conducted. Until further confirmation, therefore, Harrison et al.'s proposal can only be considered to be a working hypothesis.

  2. A hybrid phenomenological model for ferroelectroelastic ceramics. Part II: Morphotropic PZT ceramics

    Science.gov (United States)

    Stark, S.; Neumeister, P.; Balke, H.

    2016-10-01

    In this part II of a two part series, the rate-independent hybrid phenomenological constitutive model introduced in part I is modified to account for the material behavior of morphotropic lead zirconate titanate ceramics (PZT ceramics). The modifications are based on a discussion of the available literature results regarding the micro-structure of these materials. In particular, a monoclinic phase and a highly simplified representation of the hierarchical structure of micro-domains and nano-domains observed experimentally are incorporated into the model. It is shown that experimental data for the commercially available morphotropic PZT material PIC151 (PI Ceramic GmbH, Lederhose, Germany) can be reproduced and predicted based on the modified hybrid model.

  3. A Lagrangian variational formulation for nonequilibrium thermodynamics. Part II: Continuum systems

    Science.gov (United States)

    Gay-Balmaz, François; Yoshimura, Hiroaki

    2017-01-01

    Part I of this paper introduced a Lagrangian variational formulation for nonequilibrium thermodynamics of discrete systems. This variational formulation extends Hamilton's principle to allow the inclusion of irreversible processes in the dynamics. The irreversibility is encoded into a nonlinear nonholonomic constraint given by the expression of entropy production associated to all the irreversible processes involved. In Part II, we develop this formulation for the case of continuum systems by extending the setting of Part I to infinite dimensional nonholonomic Lagrangian systems. The variational formulation is naturally expressed in the material representation, while its spatial version is obtained via a nonholonomic Lagrangian reduction by symmetry. The theory is illustrated with the examples of a viscous heat conducting fluid and its multicomponent extension including chemical reactions and mass transfer.

    Delp, Linda; Mojtahedi, Zahra; Sheikh, Hina; Lemus, Jackie

    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.

  5. Cooperation in Carrier Sense Based Wireless Ad Hoc Networks - Part II: Proactive Schemes

    CERN Document Server

    Munari, Andrea; Zorzi, Michele

    2012-01-01

    This work is the second of a two-part series of papers on the effectiveness of cooperative techniques in non-centralized carrier sense-based ad hoc wireless networks. While Part I extensively discussed reactive cooperation, characterized by relayed transmissions triggered by failure events at the intended receiver, Part II investigates in depth proactive solutions, in which the source of a packet exploits channel state information to preemptively coordinate with relays in order to achieve the optimal overall rate to the destination. In particular, this work shows by means of both analysis and simulation that the performance of reactive cooperation is reduced by the intrinsic nature of the considered medium access policy, which biases the distribution of the available relays, locating them in unfavorable positions for rate optimization. Moreover, the highly dynamic nature of interference that characterizes non-infrastructured ad hoc networks is proved to hamper the efficacy and the reliability of preemptively ...

  7. Formulation, computation and improvement of steady state security margins in power systems. Part II: Results

    A steady state security margin for a particular operating point can be defined as the distance from this initial point to the secure operating limits of the system. Four of the most used steady state security margins are the power flow feasibility margin, the contingency feasibility margin, the load margin to voltage collapse, and the total transfer capability between system areas. This is the second part of a two part paper. Part I has proposed a novel framework of a general model able to formulate, compute and improve any steady state security margin. In Part II the performance of the general model is validated by solving a variety of practical situations in modern real power systems. Actual examples of the Spanish power system will be used for this purpose. The same computation and improvement algorithms outlined in Part I have been applied for the four security margins considered in the study, outlining the convenience of defining a general framework valid for the four of them. The general model is used here in Part II to compute and improve: (a) the power flow feasibility margin (assessing the influence of the reactive power generation limits in the Spanish power system), (b) the contingency feasibility margin (assessing the influence of transmission and generation capacity in maintaining a correct voltage profile), (c) the load margin to voltage collapse (assessing the location and quantity of loads that must be shed in order to be far away from voltage collapse) and (d) the total transfer capability (assessing the export import pattern of electric power between different areas of the Spanish system).

    Ioppolo, S; Fedoseev, G; Minissale, M; Congiu, E; Dulieu, F; Linnartz, H

    2014-05-14

    Nitrogen oxides are considered to be important astrochemical precursors of complex species and prebiotics. However, apart from the hydrogenation of solid NO that leads to the surface formation of hydroxylamine, little is known about the full solid state reaction network involving both nitrogen and oxygen. Our study is divided into two papers, hereby called Part I and Part II. In the accompanying paper, we investigate the surface reactions NO + O/O2/O3 and NO + N with a focus on the formation of NO2 ice. Here, we complement this study by measurements of the surface destruction of solid NO2, e.g., NO2 + H/O/N. Experiments are performed in two separate ultra-high vacuum setups and therefore under different experimental conditions to better constrain the experimental results. Surface reaction products are monitored by means of Fourier Transform Reflection Absorption Infrared Spectroscopy (FT-RAIRS) and Temperature Programmed Desorption (TPD) techniques using mass spectrometry. The surface destruction of solid NO2 leads to the formation of a series of nitrogen oxides such as NO, N2O, N2O3, and N2O4 as well as HNO, NH2OH, and H2O. When NO2 is mixed with an interstellar more relevant apolar (i.e., CO) ice, solid CO2 and HCOOH are also formed due to interactions between different reaction routes. The astrophysical implications of the full nitrogen and oxygen reaction network derived from Parts I and II are discussed.

    Full Text Available This paper surveys results on complexity of the optimal recombination problem (ORP, which consists in finding the best possible offspring as a result of a recombination operator in a genetic algorithm, given two parent solutions. 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.

  11. 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.

  12. 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. Part II, Leopard's Path (2010), for flute, clarinet, violin, cello, cimbalom, and piano, is an original composition inspired by the painting of Jesse Allen, a San Francisco based artist. The composition is conceived as a cycle of thirteen short movements. Ten of these movements are

  14. Advances in Unsteady Boundary Layer Transition Research, Part II: Experimental Verification

    Directory of Open Access Journals (Sweden)

    M. T. Schobeiri

    2003-01-01

    Full Text Available This two-part article presents recent advances in boundary layer research into the unsteady boundary layer transition modeling and its validation. This, Part II, deals with the results of an inductive approach based on comprehensive experimental and theoretical studies of unsteady wake flow and unsteady boundary layer flow. The experiments were performed on a curved plate at a zero streamwise pressure gradient under periodic unsteady wake flow, in which the frequency of the periodic unsteady flow was varied. To validate the model, systematic experimental investigations were performed on the suction and pressure surfaces of turbine blades integrated into a high-subsonic cascade test facility, which was designed for unsteady boundary layer investigations. The analysis of the experiment's results and comparison with the model's prediction confirm the validity of the model and its ability to predict accurately the unsteady boundary layer transition.

    2008-08-01

    The obstetric outcome in women with kidney disease has improved in recent years due to continuous progress in obstetrics and neonatology, as well as better medical management of hypertension and renal disease. However, every pregnancy in these women remains a high-risk pregnancy. When considering the interaction between renal disease and pregnancy, maternal outcomes are related to the initial level of renal dysfunction more than to the specific underlying disease. With regards to fetal outcomes, though, a distinction may exist between renal dysfunction resulting from primary renal disease and that in which renal involvement is part of a systemic disease. In part II of this review, some specific causes of renal failure affecting pregnancy are considered.

    In veterinary medicine, the characterization of a drug's pharmacokinetic properties is generally based upon data that are derived from studies that employ small groups of young healthy animals, often of a single breed. In Part I of the series, we focused on the potential influence of disease processes, stress, pregnancy and lactation on drug pharmacokinetics. In this Part II of the series, we consider other covariates, such as gender, heritable traits, age, body composition, and circadian rhythms. The impact of these factors with respect to predicting the relationship between dose and drug exposure characteristics within an animal population is illustrated through the use of Monte Carlo simulations. Ultimately, an appreciation of these potential influences will improve the prediction of situations when dose adjustments may be appropriate. © 2010 Blackwell Publishing Ltd.

  17. Transferring diffractive optics from research to commercial applications: Part II - size estimations for selected markets

    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.

  19. Investigations about Starting Cracks in DC-Casting of 6063-Type Billets Part II: Modelling Results

    Science.gov (United States)

    Jensen, E. K.; Schneider, W.

    Influence on starting crack tendency of varying a number of casting parameters has been studied by experiments, Part I (1), and by model calculations, Part II. Both studies point to starting block shape as a most important single factor in controlling starting cracks. By using the thermal model ALSIM-2 in analysing initial experimental results, the variable heat transfer towards the starting block was determined. This made possible a satisfactory model analysis of the starting phase and likewise the formulation of a useful cracking concept. Thus by using calculated and measured liquid pool depth curve in the starting phase of casting as a basis, an effective starting block shape was found. This new shape practically eliminates the starting crack problems in extrusion billets of the AA6063 type alloys.

    The mineral resources of an area of 40,000 sq km, principally in the Department of Antioquia, but including small parts of the Departments of Caldas, C6rdoba, Risaralda, and Tolima, were investigated during the period 1964-68. The area is designated Zone II by the Colombian Inventario Minero Nacional(lMN). The geology of approximately 45 percent of this area, or 18,000 sq km, has been mapped by IMN. Zone II has been a gold producer for centuries, and still produces 75 percent of Colombia's gold. Silver is recovered as a byproduct. Ferruginous laterites have been investigated as potential sources of iron ore but are not commercially exploitable. Nickeliferous laterite on serpentinite near Ure in the extreme northwest corner of the Zone is potentially exploitable, although less promising than similar laterites at Cerro Matoso, north of the Zone boundary. Known deposits of mercury, chromium, manganese, and copper are small and have limited economic potentia1. Cement raw materials are important among nonmetallic resources, and four companies are engaged in the manufacture of portland cement. The eastern half of Zone II contains large carbonate rock reserves, but poor accessibility is a handicap to greater development at present. Dolomite near Amalfi is quarried for the glass-making and other industries. Clay saprolite is abundant and widely used in making brick and tiles in backyard kilns. Kaolin of good quality near La Union is used by the ceramic industry. Subbituminous coal beds of Tertiary are an important resource in the western part of the zone and have good potential for greater development. Aggregate materials for construction are varied and abundant. Deposits of sodic feldspar, talc, decorative stone, and silica are exploited on a small scale. Chrysotils asbestos deposits north of Campamento are being developed to supply fiber for Colombia's thriving asbestos-cement industry, which is presently dependent upon imported fiber. Wollastonite and andalusite are

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

    Energy Technology Data Exchange (ETDEWEB)

    1980-06-27

    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.

  4. Analysis of Radionuclide Releases from the Fukushima Dai-ichi Nuclear Power Plant Accident Part II

    The present part of the publication (Part II) deals with long range dispersion of radionuclides emitted into the atmosphere during the Fukushima Dai-ichi accident that occurred after the March 11, 2011 tsunami. The first part (Part I) is dedicated to the accident features relying on radionuclide detections performed by monitoring stations of the Comprehensive Nuclear Test Ban Treaty Organization network. In this study, the emissions of the three fission products Cs-137, I-131 and Xe-133 are investigated. Regarding Xe-133, the total release is estimated to be of the order of 6 × 1018 Bq emitted during the explosions of units 1, 2 and 3. The total source term estimated gives a fraction of core inventory of about 8 × 1018 Bq at the time of reactors shutdown. This result suggests that at least 80 % of the core inventory has been released into the atmosphere and indicates a broad meltdown of reactor cores. Total atmospheric releases of Cs-137 and I-131 aerosols are estimated to be 1016 and 1017 Bq, respectively. By neglecting gas/particulate conversion phenomena, the total release of I-131 (gas + aerosol) could be estimated to be 4 × 1017 Bq. Atmospheric transport simulations suggest that the main air emissions have occurred during the events of March 14, 2011 (UTC) and that no major release occurred after March 23. The radioactivity emitted into the atmosphere could represent 10 % of the Chernobyl accident releases for I-131 and Cs-137.

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

    LENUS (Irish Health Repository)

    Killeen, Ronan P

    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.

  9. Constructions of Optical Queues With a Limited Number of Recirculations--Part II: Optimal Constructions

    CERN Document Server

    Huang, Xuan-Chao

    2010-01-01

    One of the main problems in all-optical packet-switched networks is the lack of optical buffers, and one feasible technology for the constructions of optical buffers is to use optical crossbar Switches and fiber Delay Lines (SDL). In this two-part paper, we consider SDL constructions of optical queues with a limited number of recirculations through the optical switches and the fiber delay lines. Such a problem arises from practical feasibility considerations. In Part I, we have proposed a class of greedy constructions for certain types of optical queues, including linear compressors, linear decompressors, and 2-to-1 FIFO multiplexers, and have shown that every optimal construction among our previous constructions of these types of optical queues under the constraint of a limited number of recirculations must be a greedy construction. In Part II, the present paper, we further show that there are at most two optimal constructions and give a simple algorithm to obtain the optimal construction(s). The main idea i...

    2014-05-01

    There are a multitude of diseases that commonly affect both the skin and the eye. Part II of this 2-part series reviews the oculocutaneous manifestations of neoplasms, both benign and malignant, and adverse drug reactions affecting the skin and the eye. Though rare, a number of neoplasms that primarily involve the skin, such as melanoma and basal cell carcinoma, can metastasize to the eye, leading to permanent damage if not properly treated. In addition, periocular neoplasms can irritate the conjunctiva and lid, reducing a patient's ability to see clearly. Neoplastic diseases, such as xeroderma pigmentosum, Sturge-Weber syndrome, and multiple myeloma, can also lead to permanent changes in the eye if not discovered and managed promptly. Furthermore, there are a multitude of drugs, including those commonly used by dermatologists, which can result in permanent damage to the eye. With proper knowledge of the ocular manifestations and treatment recommendations described in this 2-part series, dermatologists with the assistance of their ophthalmology colleagues can help avoid the complications, including permanent blindness, associated with infectious, inflammatory, genetic, neoplastic, and drug-related conditions.

    Construction in and around a working perioperative suite is a challenge beyond merely managing traffic patterns and maintaining the sterile field. The AORN "Recommended practices for a safe environment of care, part II" provides guidance on building design; movement of patients, personnel, supplies, and equipment; environmental controls; safety and security; and control of noise and distractions. Whether the OR suite evolves through construction, reconstruction, or remodeling, a multidisciplinary team of construction experts and health care professionals should create a functional plan and communicate at every stage of the project to maintain a safe environment and achieve a well-designed outcome. Emergency preparedness, a facility-wide security plan, and minimization of noise and distractions in the OR also help enhance the safety of the perioperative environment.

    Gorris, Hans H; Resch-Genger, Ute

    2017-07-07

    In Part II of this review series on lanthanide-doped photon-upconversion nanoparticles (UCNPs), we present and critically discuss the performance and suitability of UCNPs as background-free luminescent reporters in bioimaging and bioanalytical applications. The preparation of a biocompatible nanoparticle surface is an integral step for all life - science-related applications. UCNPs have found their way into a large number of diagnostic platforms, homogeneous and heterogeneous assay formats, and sensor applications. Many bioanalytical detection schemes involve Förster resonance energy transfer (FRET), which is still debated for UCNPs and needs to be much improved. The need for dedicated and standardized instruments as well as recent studies on the dissolution and potential toxicity of UCNPs are addressed. Finally we outline future trends and challenges in the field of upconversion. Graphical Abstract Both synthesis / spectroscopy as well bioanalytical applications of UCNPs are driven by the COST Action CM1403 "The European Upconversion Network".

    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.

    Part II of this comprehensive review on magnetic resonance imaging of the elbow discusses the role of magnetic resonance imaging in evaluating patients with abnormalities of the ligaments, tendons, and nerves of the elbow. Magnetic resonance imaging can yield high-quality multiplanar images which are useful in evaluating the soft tissue structures of the elbow. Magnetic resonance imaging can detect tears of the ulnar collateral ligament and lateral collateral ligament of the elbow with high sensitivity and specificity. Magnetic resonance imaging can determine the extent of tendon pathology in patients with medial epicondylitis and lateral epicondylitis. Magnetic resonance imaging can detect tears of the biceps tendon and triceps tendon and can distinguishing between partial and complete tendon rupture. Magnetic resonance imaging is also helpful in evaluating patients with nerve disorders at the elbow. (orig.)

    Wotton, Karen; Redden, Maurine

    2002-08-01

    Third-space fluid shift is the mobilisation of body fluid to a non-contributory space rendering it unavailable to the circulatory system. It is a recurrent clinical phenomenon requiring swift identification to minimise deleterious effects. Nurses experience difficulties however in its early identification, diagnosis and subsequent treatment because of the lack of consensual and consistent information regarding third-spacing. This article, part II, building on the previous article, explores the clinical validly and reliability of signs and symptoms of both phases of third-space fluid shift. In addition it reinforces the use multiple patient assessment cues if nurses are to differentiate between, and accurately respond to, the various causes of both hypovolaemia and hypervolaemia. It assists nurses to increase their knowledge and uderstanding of third-space fluid shift in patients undergoing gastrointestinal surgery.

    2010-05-01

    Melanocytic lesions show great morphological diversity in their architecture and the cytomorphological appearance of their composite cells. Whereas functional melanocytes show a dendritic cytomorphology and territorial isolation, lesional nevomelanocytes and melanoma cells typically show epithelioid, spindled or mixed cytomorphologies, and a range of architectural arrangements. Spindling is common to melanocytic lesions, and may either be a characteristic feature or a divergent appearance. The presence of spindle cells may mask the melanocytic nature of a lesion, and is often disconcerting, either due to its infrequent appearance in a particular lesion or its interpretation as a dedifferentiated phenotype. Spindle cell melanocytic lesions follow the full spectrum of potential biological outcomes, and difficulty may be experienced judging the nature of a lesion due to a lack of consistently reliable features to predict biological behaviour. Over time, recognition of numerous histomorphological features that may portend a more aggressive lesion have been identified; however, the translation of these features into a diagnostic entity requires a gestalt approach. Although most spindle cell melanocytic lesions may reliably be resolved through this standard approach, problem areas do exist for the surgical pathologist or dermatopathologist. With this review (part II of II), we complete our discussion of spindle cell melanocytic lesions, in order to: (1) model a systematic approach to such lesions; and (2) provide familiarity with those melanocytic lesions which either typically or occasionally display a spindled cytomorphology.

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

    Directory of Open Access Journals (Sweden)

    Yuan Yang

    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.

  2. Modeling of optical spectra of the light-harvesting CP29 antenna complex of photosystem II--part II.

    Science.gov (United States)

    Feng, Ximao; Kell, Adam; Pieper, Jörg; Jankowiak, Ryszard

    2013-06-01

    Until recently, it was believed that the CP29 protein from higher plant photosystem II (PSII) contains 8 chlorophylls (Chl's) per complex (Ahn et al. Science 2008, 320, 794-797; Bassi et al. Proc. Natl. Acad. Sci. U.S.A. 1999, 96, 10056-10061) in contrast to the 13 Chl's revealed by the recent X-ray structure (Pan et al. Nat. Struct. Mol. Biol. 2011, 18, 309-315). This disagreement presents a constraint on the interpretation of the underlying electronic structure of this complex. To shed more light on the interpretation of various experimental optical spectra discussed in the accompanying paper (part I, DOI 10.1021/jp4004328 ), we report here calculated low-temperature (5 K) absorption, fluorescence, hole-burned (HB), and 300 K circular dichroism (CD) spectra for CP29 complexes with a different number of pigments. We focus on excitonic structure and the nature of the low-energy state using modeling based on the X-ray structure of CP29 and Redfield theory. We show that the lowest energy state is mostly contributed to by a612, a611, and a615 Chl's. We suggest that in the previously studied CP29 complexes from spinach (Pieper et al. Photochem. Photobiol.2000, 71, 574-589) two Chl's could have been lost during the preparation/purification procedure, but it is unlikely that the spinach CP29 protein contains only eight Chl's, as suggested by the sequence homology-based study (Bassi et al. Proc. Natl. Acad. Sci. U.S.A.1999, 96, 10056-10061). The likely Chl's missing in wild-type (WT) CP29 complexes studied previously (Pieper et al. Photochem. Photobiol. 2000, 71, 574-589) include a615 and b607. This is why the nonresonant HB spectra shown in that reference were ~1 nm blue-shifted with the low-energy state mostly localized on about one Chl a (i.e., a612) molecule. Pigment composition of CP29 is discussed in the context of light-harvesting and excitation energy transfer.

    The Intervention Wheel is a population-based practice model that encompasses three levels of practice (community, systems, and individual/family) and 17 public health interventions. Each intervention and practice level contributes to improving population health. The Intervention Wheel, previously known as the Public Health Intervention Model, was originally introduced in 1998 by the Minnesota Department of Health, Section of Public Health Nursing (PHN). The model has been widely disseminated and used throughout the United States since that time. The evidence supporting the Intervention Wheel was recently subjected to a rigorous critique by regional and national experts. This critical process, which involved hundreds of public health nurses, resulted in a more robust Intervention Wheel and established the validity of the model. The critique also produced basic steps and best practices for each of the 17 interventions. Part I describes the Intervention Wheel, defines population-based practice, and details the recommended modifications and validation process. Part II provides examples of the innovative ways that the Intervention Wheel is being used in public health/PHN practice, education, and administration. The two articles provide a foundation and vision for population-based PHN practice and direction for improving population health.

    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.

  8. CFD analysis of the ITER first wall 06 panel. Part II: Thermal-hydraulics

    The computational fluid dynamics (CFD) analysis of the FW06 panel of the ITER shielding blanket is presented in two companion papers. In this Part II we concentrate on the thermal-hydraulics of the water coolant, driven by the nuclear volumetric and plasma surface heat loads discussed in Part I. Both the detailed steady state analysis of a single cooling channel and the coarse transient analysis of the whole panel are considered. The compatibility of the hot spots with the maximum recommended temperatures for the different materials is confirmed. The heat transfer coefficient between coolant and walls is obtained post-processing the results of the simulation and compared with the results of available correlations, which may be used for simpler analyses: in the fully developed flow regions of the cooling pipes, it turns out to be well approximated by the Sieder–Tate correlation. The operation margin with respect to the critical heat flux is also computed and turns out to be sufficiently large compared with the design limit.

    2016-05-01

    Part I of this article included a pertinent review of allogeneic hematopoietic cell transplantation (alloHCT), the role of postgraft immunosuppression in alloHCT, and the pharmacokinetics, pharmacodynamics, and pharmacogenomics of the calcineurin inhibitors and methotrexate. In this article (Part II), we review the pharmacokinetics, pharmacodynamics, and pharmacogenomics of mycophenolic acid (MPA), sirolimus, and the antithymocyte globulins (ATG). We then discuss target concentration intervention (TCI) of these postgraft immunosuppressants in alloHCT patients, with a focus on current evidence for TCI and on how TCI may improve clinical management in these patients. Currently, TCI using trough concentrations is conducted for sirolimus in alloHCT patients. Several studies demonstrate that MPA plasma exposure is associated with clinical outcomes, with an increasing number of alloHCT patients needing TCI of MPA. Compared with MPA, there are fewer pharmacokinetic/dynamic studies of rabbit ATG and horse ATG in alloHCT patients. Future pharmacokinetic/dynamic research of postgraft immunosuppressants should include '-omics'-based tools: pharmacogenomics may be used to gain an improved understanding of the covariates influencing pharmacokinetics as well as proteomics and metabolomics as novel methods to elucidate pharmacodynamic responses.

    Kovacheva, Mary; Jordanova, Neli; Karloukovski, Vassil

    The knowledge about past secular variations of the geomagnetic field is achieved on the basis of archaeomagnetic researches of which the Bulgarian studies form an extended data set. In Part I (Kovacheva and Toshkov, 1994), the methodology used in the Sofia palaeomagnetic laboratory was described and the secular variation curves for the last 2000 years were shown. In Part II (this paper), the basic characteristics of the prehistoric materials used in the archaeomagnetic studies are emphasised, particularly in the context of the rock magnetic studies used in connection with palaeointensity determinations. The results of magnetic anisotropy studies of the prehistoric ovens and other fired structures are summarised, including the anisotropy correction of the palaeointensity results for prehistoric materials, different from bricks and pottery. Curves of the direction and intensity of the geomagnetic field during the last 8000 years in Bulgaria are given. The available directional and intensity values have been used to calculate the variation curve of the virtual dipole moment (VDM) for the last 8000 years based on different time interval averages. The path of virtual geomagnetic pole (VGP) positions is discussed.

  11. Polarized light scanning cryomacroscopy, part II: Thermal modeling and analysis of experimental observations.

    2016-10-01

    This study aims at developing thermal analysis tools and explaining experimental observations made by means of polarized-light cryomacroscopy (Part I). Thermal modeling is based on finite elements analysis (FEA), where two model parameters are extracted from thermal measurements: (i) the overall heat transfer coefficient between the cuvette and the cooling chamber, and (ii) the effective thermal conductivity within the cryoprotective agent (CPA) at the upper part of the cryogenic temperature range. The effective thermal conductivity takes into account enhanced heat transfer due to convection currents within the CPA, creating the so-called Bénard cells. Comparison of experimental results with simulation data indicates that the uncertainty in simulations due to the propagation of uncertainty in measured physical properties exceeds the uncertainty in experimental measurements, which validates the modeling approach. It is shown in this study that while a cavity may form in the upper-center portion of the vitrified CPA, it has very little effect on estimating the temperature distribution within the domain. This cavity is driven by thermal contraction of the CPA, with the upper-center of the domain transitioning to glass last. Finally, it is demonstrated in this study that additional stresses may develop within the glass transition temperature range due to nonlinear behavior of the thermal expansion coefficient. This effect is reported here for the first time in the context of cryobiology, using the capabilities of polarized-light cryomacroscopy.

  12. A Model of Biocomplexity in River Networks - Part II: Tenets and Predictions

    Science.gov (United States)

    Delong, M. D.; Thorp, J. H.; Thoms, M. C.

    2005-05-01

    We are proposing a model of lotic biocomplexity encompassing spatiotemporal scales from headwaters to large rivers and from main channels to floodplains. Part I of our presentation in the symposium discusses the general theory and predicted changes along longitudinal gradients in the river network. In Part II, we use the foundation of this theory to make predictions for the ecological behavior of the river ecosystem. These predictions are designed to stimulate research tests of these hypotheses and to obtain data allowing the continuing refinement of the overall model. Fourteen principles or model tenets are included which describe the functioning of epigean portions of lotic ecosystems on ecological time scales; they are focused more on the riverscape than the entire riverine landscape. These 14 tenets predict how patterns of individual species distributions, community regulation, lotic ecosystem processes, and floodplain interactions will vary over spatiotemporal scales, especially as they relate to the functional process zones formed by hydrogeomorphic patches. We make no claim to originality for all these tenets. Some of these ideas are well supported in the scientific literature, others may be acceptable to the scientific community but currently lack empirical support, and some may be very speculative and possibly controversial.

    Madineh, Sayed Mohammad Ali

    2009-01-01

    In the previous issue of the Urology Journal, a comparison of Avicenna's Canon of Medicine with modern urologic findings was done in part I of this article, addressing bladder anatomy and physiology and bladder calculi. In part II of this review, the remaining chapters of the Canon of Medicine on bladder calculi are reviewed. Avicenna points to perineal urethrostomy (perineostomy), which is today performed as the last therapeutic line or as a temporary remedy before surgical treatment. He also describes surgery via transperineal route and warns the surgeon of the proximity of vasa deferentia, prostate gland, and neurovascular bundle and their exposure in this position. Usage of grasping forceps for removal of bladder calculus and emphasis on removing all calculus fragments are the interesting points of this chapter. Avicenna explains a technique similar to the use of a Babcock forceps for prevention of calculus migration. Complications of bladder calculus surgery and cystostomy are also addressed with scientific precision in the Canon. It is noteworthy that 8 centuries before Fournier described necrotizing fasciitis in male genitalia, Avicenna had described Fournier gangrene in his book.

    The newly developed spherical smart aggregate (SSA) based on a radially polarized spherical piezoceramic shell element has unique omnidirectional actuating and sensing capabilities that can greatly improve the detection aperture and provide additional functionalities in health monitoring applications in concrete structures. Detailed fabrication procedures and electrical characterization of the SSA have been previously studied (Part I). In this second paper (Part II), the functionalities of the SSA used in both active sensing and passive sensing approaches were investigated in experiments and numerical simulations. One SSA sample was embedded in a 1 ft3 concrete specimen. In the active sensing approach, the SSA was first utilized as an actuator to generate stress waves and six conventional smart aggregates (SA) mounted on the six faces of the concrete cube were utilized as sensors to detect the wave response. Conversely, the embedded SSA was then utilized as a sensor to successively detect the wave response from each SA. The experimentally obtained behavior of the SSA was then compared with the numerical simulation results. Further, a series of impact tests were conducted to verify the performance of the SSA in the detection of the impact events from different directions. Comparison with the wave response associated with different faces of the cube verified the omnidirectional actuating and sensing capabilities of the SSA.

    A non-linear lumped kineto-elastodynamic model for the prediction of the dynamic behaviour of external gear pumps is presented. It takes into account the most important phenomena involved in the operation of this kind of machines. Two main sources of noise and vibration can be considered: pressure and gear meshing. Fluid pressure distribution on gears, which is time-varying, is computed and included as a resultant external force and torque acting on the gears. Parametric excitations due to time-varying meshing stiffness, the tooth profile errors (obtained by a metrological analysis), the backlash effects between meshing teeth, the lubricant squeeze and the possibility of tooth contact on both lines of action were also included. Finally, the torsional stiffness and damping of the driving shaft and the non-linear behaviour of the hydrodynamic journal bearings were also taken into account. Model validation was carried out on the basis of experimental data concerning case accelerations and force reactions. The model can be used in order to analyse the pump dynamic behaviour and to identify the effects of modifications in design and operation parameters, in terms of vibration and dynamic forces. Part I is devoted to the calculation of the gear eccentricity in the steady-state condition as result of the balancing between mean pressure loads, mean meshing force and bearing reactions, while in Part II the meshing phenomena are fully explained and the main simulation results are presented.

    Wang, Dan; Gao, Guangping

    2014-09-01

    In Part I of this Review (Wang and Gao, 2014), we introduced recent advances in gene delivery technologies and explained how they have powered some of the current human gene therapy applications. In Part II, we expand the discussion on gene therapy applications, focusing on some of the most exciting clinical uses. To help readers to grasp the essence and to better organize the diverse applications, we categorize them under four gene therapy strategies: (1) gene replacement therapy for monogenic diseases, (2) gene addition for complex disorders and infectious diseases, (3) gene expression alteration targeting RNA, and (4) gene editing to introduce targeted changes in host genome. Human gene therapy started with the simple idea that replacing a faulty gene with a functional copy can cure a disease. It has been a long and bumpy road to finally translate this seemingly straightforward concept into reality. As many disease mechanisms unraveled, gene therapists have employed a gene addition strategy backed by a deep knowledge of what goes wrong in diseases and how to harness host cellular machinery to battle against diseases. Breakthroughs in other biotechnologies, such as RNA interference and genome editing by chimeric nucleases, have the potential to be integrated into gene therapy. Although clinical trials utilizing these new technologies are currently sparse, these innovations are expected to greatly broaden the scope of gene therapy in the near future.

  18. Diagnosing DSM-IV--Part II: Eysenck (1986) and the essentialist fallacy.

    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.

    Several different methods can be employed to test for gunshot residue (GSR) on a decedent's hands, including scanning electron microscopy with energy dispersive x-ray (SEM/EDX) and inductive coupled plasma-atomic emission spectrometry (ICP-AES). In part I of this 2-part series, GSR results performed by SEM/EDX in undisputed cases of suicidal handgun wounds were studied. In part II, the same population was studied, deceased persons with undisputed suicidal handgun wounds, but GSR testing was performed using ICP-AES. A total of 102 cases were studied and analyzed for caliber of weapon, proximity of wound, and the results of the GSR testing. This study found that 50% of cases where the deceased was known to have fired a handgun immediately prior to death had positive GSR results by ICP/AES, which did not differ from the results of GSR testing by SEM/EDX. Since only 50% of cases where the person is known to have fired a weapon were positive for GSR by either method, this test should not be relied upon to determine whether someone has discharged a firearm and is not useful as a determining factor of whether or not a wound is self-inflicted or non-self-inflicted. While a positive GSR result may be of use, a negative result is not helpful in the medical examiner setting as a negative result indicates that either a person fired a weapon prior to death or a person did not fire a weapon prior to death.

    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.

    Part I of this report focused on the acquisition and presentation of transient PVT data sets that can be used to validate gas transfer models. Here in Part II we focus primarily on describing models and validating these models using the data sets. Our models are intended to describe the high speed transport of compressible gases in arbitrary arrangements of vessels, tubing, valving and flow branches. Our models fall into three categories: (1) network flow models in which flow paths are modeled as one-dimensional flow and vessels are modeled as single control volumes, (2) CFD (Computational Fluid Dynamics) models in which flow in and between vessels is modeled in three dimensions and (3) coupled network/CFD models in which vessels are modeled using CFD and flows between vessels are modeled using a network flow code. In our work we utilized NETFLOW as our network flow code and FUEGO for our CFD code. Since network flow models lack three-dimensional resolution, correlations for heat transfer and tube frictional pressure drop are required to resolve important physics not being captured by the model. Here we describe how vessel heat transfer correlations were improved using the data and present direct model-data comparisons for all tests documented in Part I. Our results show that our network flow models have been substantially improved. The CFD modeling presented here describes the complex nature of vessel heat transfer and for the first time demonstrates that flow and heat transfer in vessels can be modeled directly without the need for correlations.

    Simulated inter-annual to decadal variability and trends in the North Atlantic for the 1958-2007 period from twenty global ocean - sea-ice coupled models are presented. These simulations are performed as contributions to the second phase of the Coordinated Ocean-ice Reference Experiments (CORE-II). The study is Part II of our companion paper (Danabasoglu et al., 2014) which documented the mean states in the North Atlantic from the same models. A major focus of the present study is the representation of Atlantic meridional overturning circulation (AMOC) variability in the participating models. Relationships between AMOC variability and those of some other related variables, such as subpolar mixed layer depths, the North Atlantic Oscillation (NAO), and the Labrador Sea upper-ocean hydrographic properties, are also investigated. In general, AMOC variability shows three distinct stages. During the first stage that lasts until the mid- to late-1970s, AMOC is relatively steady, remaining lower than its long-term (1958-2007) mean. Thereafter, AMOC intensifies with maximum transports achieved in the mid- to late-1990s. This enhancement is then followed by a weakening trend until the end of our integration period. This sequence of low frequency AMOC variability is consistent with previous studies. Regarding strengthening of AMOC between about the mid-1970s and the mid-1990s, our results support a previously identified variability mechanism where AMOC intensification is connected to increased deep water formation in the subpolar North Atlantic, driven by NAO-related surface fluxes. The simulations tend to show general agreement in their temporal representations of, for example, AMOC, sea surface temperature (SST), and subpolar mixed layer depth variabilities. In particular, the observed variability of the North Atlantic SSTs is captured well by all models. These findings indicate that simulated variability and trends are primarily dictated by the atmospheric datasets which

    During part II of this research program combustible sludge from the pulp and paper industry has been studied in detail. 560,000 tonnes of sludge per year (calculated as dry sludge) are produced in Sweden. The energy potential in the produced sludge is about 2 TWh/year. Today 1 TWh/year is produced in the pulp and paper mill's own boilers. This means that additional energy can be utilized from this material. An objective of this program has been to decide whether or not there are sludge types which are favourable respectively difficult to combust. By mixing different sludge types, or other waste products, emissions and/or problems during combustion can be minimized. These possibilities have been studied thoroughly in this program. A lot of sludge samples have been studied in laboratory scale at SP and in full-scale at Chalmers 12 MW CFB boiler. As a complement to the practical tests S.E.P. has done research regarding different aspects of sludge as a fuel; for example handling of sludge and regional drying. The results of 40 sintering tests at SP showed that the sintering temperature during combustion of sludge in a fluidised bed, with silica sand as bed material, varied between <850 deg C and >1100 deg C. The evaluation showed that the alkali content in the ash had the largest influence on the sintering temperature. Other factors were less important. During the tests at Chalmers eleven different sludge samples have been combusted together with wood pellets. Initially there were problems with the feeding to the boiler for some of the sludge samples. When the fuel feeding problems were solved the combustion took place without any problems. When sludge is co-combusted together with a 'clean' base fuel such as wood pellets the sulphur-, nitrogen- and chloride contents in the sludge have a large impact on the emissions. The normal way to reduce sulphur dioxide but also hydrogen chloride is to add lime in different positions into and after the boiler. In

La investigación analiza el cumplimiento de las leyes mexicanas en materia de riesgos laborales por parte de las maquiladoras del ramo de la electrónica. La hipótesis central consiste en mostrar cómo la observancia de las leyes sobre riesgos laborales por parte de las empresas, se explica en mayor medida por las características laborales e industriales de cada localidad que por el temor a las sanciones legales de su no cumplimiento. A partir del análisis de las tres ciudades fronterizas más importantes en Tamaulipas, Matamoros, Reynosa y Nuevo Laredo, las autoras distinguen diferentes niveles de cumplimiento de la ley, los cuales están más en relación con el tamaño, tipo y requerimientos industriales de cada planta, que con una observancia real de las leyes mexicanas.

    Two cardiovascular outcome trials established niacin 3 g daily prevents hard cardiac events. However, as detailed in part I of this series, an extended-release (ER) alternative at only 2 g nightly demonstrated no comparable benefits in two outcome trials, implying the alternative is not equivalent to the established cardioprotective regimen. Since statins leave a significant treatment gap, this presents a major opportunity for developers. Importantly, the established regimen is cardioprotective, so the pathway is likely beneficial. Moreover, though effective, the established cardioprotective regimen is cumbersome, limiting clinical use. At the same time, the ER alternative has been thoroughly discredited as a viable substitute for the established cardioprotective regimen. Therefore, by exploiting the pathway and skillfully avoiding the problems with the established cardioprotective regimen and the ER alternative, developers could validate cardioprotective variations facing little meaningful competition from their predecessors. Thus, shrewd developers could effectively tap into a gold mine at the grave of the ER alternative. The GPR109A receptor was discovered a decade ago, leading to a large body of evidence commending the niacin pathway to a lower cardiovascular risk beyond statins. While mediating niacin's most prominent adverse effects, GPR109A also seems to mediate anti-lipolytic, anti-inflammatory, and anti-atherogenic effects of niacin. Several developers are investing heavily in novel strategies to exploit niacin's therapeutic pathways. These include selective GPR109A receptor agonists, niacin prodrugs, and a niacin metabolite, with encouraging early phase human data. In part II of this review, we summarize the accumulated results of these early phase studies of emerging niacin mimetics.

    This work is Part II of an integrated experimental/modeling investigation of a procedure to coat nanofibers and core-clad nanostructures with thin-film materials using plasma-enhanced physical vapor deposition. In the experimental effort, electrospun polymer nanofibers are coated with aluminum materials under different operating conditions to observe changes in the coating morphology. This procedure begins with the sputtering of the coating material from a target. Part I [J. Appl. Phys. 98, 044303 (2005)] focused on the sputtering aspect and transport of the sputtered material through the reactor. That reactor level model determines the concentration field of the coating material. This field serves as input into the present species transport and deposition model for the region surrounding an individual nanofiber. The interrelationships among processing factors for the transport and deposition are investigated here from a detailed modeling approach that includes the salient physical and chemical phenomena. Solution strategies that couple continuum and atomistic models are used. At the continuum scale, transport dynamics near the nanofiber are described. At the atomic level, molecular dynamics (MD) simulations are used to study the deposition and sputtering mechanisms at the coating surface. Ion kinetic energies and fluxes are passed from the continuum sheath model to the MD simulations. These simulations calculate sputtering and sticking probabilities that in turn are used to calculate parameters for the continuum transport model. The continuum transport model leads to the definition of an evolution equation for the coating-free surface. This equation is solved using boundary perturbation and level set methods to determine the coating morphology as a function of operating conditions.

    Full Text Available El presente artículo se centra en analizar desde una perspectiva teórico-práctica el comportamiento del riesgo crediticio, calce de plazos y tasas de interés en el conjunto de la banca comercial y universal venezolana para el trienio 1998-2000, años éstos donde las políticas económicas experimentaron comportamientos de diferente corte. A través de una investigación de tipo descriptivo-observacional, los resultados revelan que este importante segmento del sector financiero presentó una exposición al riesgo de calce de plazos al obtener pasivos conformados por depósitos a corto plazo en relación a la tenencia de activos en préstamos a mediano y largo plazo. Igualmente se concluye, el buen desempeño del entorno económico reduce las posibilidades que el sistema financiero se enfrente al riesgo crediticio, dada la mejor posición financiera de los agentes económicos demandantes de fondos prestables. Por su parte, el riesgo de tasas de interés no estuvo presente en el sistema bancario venezolano durante el periodo de estudio, dada la disposición por parte de las políticas monetarias en tratar de bajar el diferencial entre las tasas de interés activas y pasivas, sin que este diferencial se tornara negativo para este importante sector del sistema financiero venezolano.

    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 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.

    Redox equilibria and titration play an important role in chemical analysis, and the formulation of an accurate mathematical description is a challenge. This article is devoted to static and (mainly) dynamic redox systems; the dynamic systems are represented by redox titrations. An overview addresses earlier approaches to static redox systems (redox diagram plots, including Pourbaix diagrams) and to titration redox systems, thereby covering a gap in the literature. After this short review, the generalized approach to electrolytic systems (GATES) is introduced, with generalized electron balance (GEB) as its inherent part within GATES/GEB. Computer simulation, performed according to GATES/GEB, enables following the changes in potential and pH of the solution, together with chemical speciation at each step of a titration, thus providing better insight into this procedure. The undeniable advantages of GATES/GEB over earlier approaches are indicated. Formulation of GEB according to two approaches (I and II) is presented on the respective examples. A general criterion distinguishing between non-redox and redox systems is presented. It is indicated that the formulation of GEB according to Approach II does not need the knowledge of oxidation degrees of particular elements; knowledge of the composition, expressed by chemical formula of the species and its charge, is sufficient for this purpose. Approach I to GEB, known also as the "short" version of GEB, is applicable if oxidation degrees for all elements of the system are known beforehand. The roles of oxidants and reductants are not ascribed to particular components forming a system and to the species thus formed. This is the complete opposite of earlier approaches to redox titrations, based on the stoichiometric redox reaction, formulated for this purpose. GEB, perceived as a law of matter conservation, is fully compatible with other (charge and concentration) balances related to the system in question. The applicability

    In the Persantine-Aspirin Reinfarction Study, Part II (PARIS II), 3,128 persons who had recovered from myocardial infarction, suffered from 4 weeks to 4 months previously, were randomized into two groups: dipyridamole (Persantine) plus aspirin (n = 1,563) and placebo (n = 1,565). The average length of follow-up was 23.4 months. Prespecified primary end points were coronary incidence (definite nonfatal myocardial infarction plus death due to recent or acute cardiac event), coronary mortality (death due to recent or acute cardiac event) and total mortality, each at 1 year of patient follow-up and at the end of the study. Coronary incidence in the Persantine plus aspirin group was significantly lower than in the placebo group, both at 1 year (30% reduction) and at the end of the study (24% reduction). The statistically significant differences in coronary incidence, at 1 year and at the end of the study, in favor of the combination treatment remained after adjustment for multiple baseline variables and adjustment for multiple testing (three end points for two time periods). Although there were reductions for other end points, these differences were not statistically significant. Coronary mortality was 20% lower in the Persantine plus aspirin group compared with the placebo group at 1 year, and 6% lower overall. Total mortality in the treated group compared with the placebo group was 11% lower at 1 year and 3% lower overall. The reduced rates of coronary incidence largely reflected lower rates of definite nonfatal myocardial infarction in the Persantine plus aspirin group. Several subgroups were defined a priori and at the end of the study. The beneficial effect of Persantine plus aspirin compared with placebo for coronary incidence tended to be greater for the following groups of patients: those who had a non-Q wave infarct; those who were not taking digitalis; those who were receiving beta-receptor blocking drugs at baseline; those who were in New York Heart

    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.

    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

    2006-01-01

    Tobacco was brought to Europe by Christopher Columbus, who discovered it in Cuba in October, 1492. Spread of tobacco consumption was initiated by the French diplomat Jean Nicot de Villemain, who in 1560 recommended it in the form of powdered tobacco leaves to the French Queen Catherine de Medice to combat her migraine headaches, and introduced the term Nicotiana tobaccum. Tobacco consumption greatly rose after the I World War, and after the II World War it became very common, especially among man. In the first half of the 20th century the sale of tobacco products rose by 61%, and cigarettes dominated the market of tobacco products. At the beginning of the 20th century cigarettes constituted only 2% of the total sale of tobacco products, while in the middle of the 20th century--more than 80%. Although the first epidemiological papers indicating that "smoking is connected with the shortening of life span" were published in the first half of the 20th century, not until 1950 did Hill and Doll in Great Britain, and Wynder and Graham in USA in 1951 show a statistically significant correlation between cigarettes smoking and lung cancer occurrence. Many controversies according the use of tobacco accompanied it from the beginning of its presence in Europe. The conflicting opinions according to its influence to health coexisted in the 16th to 19th centuries. In this period, especially in the 19th century dominated moral and religious arguments against tobacco. In the 20th century however, and particularly in its second part, development in medical research was enhanced by civil voluntary actions against advertisement and passive smoking. This lead to the significant limitation of tobacco expansion in Europe, USA and Canada in the end of the 20th century.

    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.

    Full Text Available Four years data of temperature from the coastal areas of Santos and Cananeia are analysed in continuation of part I of this work. Earlier tidal wave theories for coastal areas and some basic processes on the determination of Nz are summarized. Seasonal variations of temperature are found to obey approximately a general harmonic law of propagation with depth and from it estimates of the mean annual values of N are obtained. These estimates (preliminaries seem to indicate that mixing at the coastal areas of Santos is smaller than in the ones of Cananéia.

  1. IrII(ethene): metal or carbon radical? Part II: oxygenation via iridium or direct oxygenation at ethene?

    2005-03-07

    Treatment of [(Me3tpa)IrII(ethene)]2+ (Me(3)tpa =N,N,N-tri(6-methyl-2-pyridylmethyl)amine)(1(2+)) with dioxygen in weakly coordinating solvents results in formation of [(Me3tpa)IrIII(ethene)(superoxo)]2+ (4a2+). In the presence of DMPO (DMPO = 5,5-dimethyl-2-pyrrolidine-1-oxide) DMPO is substituted for ethene, and subsequently oxidized to DMPOX by the superoxo fragment to give [(Me3tpa)IrIII(DMPOX)]2+ (7(2+); DMPOX = 5,5-dimethyl-2-pyrrolidone-1-oxide). In acetonitrile, in the absence of DMPO, oxygenation of 1(2+) to [(Me3tpa)IrIII(formylmethyl)(MeCN)]2+ (2(2+)) is observed. In the presence of DMPO the formation of 2(2+) and 7(2+) is competing. Oxygenation of 1(2+) to 2(2+) may proceed via 4a(2+), involving an insertion mechanism at the metal. However, a mechanism based on olefin ligand non-innocence seems a reasonable alternative. This involves formation of acetonitrile adduct [(Me3tpa)Ir(ethene)(MeCN)]2+ (3(2+)), which has a significant metalla-ethyl radical (IrIII-CH2CH2*) character, allowing attack of 3O2 directly at the ethene ligand. Both pathways are discussed on the basis of experimental observations and DFT geometry optimizations.

    In Part II of this review on citrus fruits, the literature on chemistry, technology, and quality evaluation are critically considered. Sweet oranges, mandarin, grapefruit, lemon, and lime are generally used for processing. The literature on chemical components of citrus fruit which include sugars, polysaccharides, organic acids, nitrogenous constituents and lipids; carotenoids which contribute to color; vitamins and minerals and flavonoids; limonoids, some of which impart bitterness to the juice; and the volatile components which contribute to aroma were reviewed in section A. Chilled and pasteurized juices, juice concentrates, and beverages are the important products manufactured commercially, and to a limited extent powdered citrus juices, canned segments, and marmalades. The literature on the manufacture of these products also as new types of juice and oil extractors; TASTE and other types of evaporators; tank farms to store juice and concentrate in bulk; aseptic filling in bulk containers and retail packs; alternate flexible and rigid containers other than glass and tin; and recovery of volatile flavoring constituents during juice processing are some of the important technological developments in the recent past and have been discussed in this section. Bitterness in citrus juices and its control, composition of cloud, and its stability and changes during storage have been reviewed. Essential oils, pectin, frozen and dried juice sacs, dried pulp and molasses, flavonoids, seed oil, and meal are the important byproducts, the manufacture of which is given in essential details. Generally, consumers judge the product on the basis of its sensory attributes. The quality of finished product is dependent upon the raw materials used and control of processes. In section C, the U.S. Department of Agriculture (USDA) standards for different products, physicochemical and microbiological parameters prescribed as indices of quality of fruit, juice, concentrate, and other

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

    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

Os espectros Raman de cerâmicas sinterizadas mostram as bandas típicas associadas aos modos ativos da fase cristalográfica tetragonal. Os resultados de espectroscopia de impedância são similares aos obtidos por outros pesquisadores tanto para cerâmicas convencionais quanto nanofásicas no caso da Y-TZP. Para a Ce-TZP foi observada uma redução na condutividade extrínseca em conseqüência da maior pureza do precursor cristalizado.Results on dense ZrO2: 3 mol% Y2O3 (Y-TZP and 12 mol% CeO2 (Ce-TZP ceramics are shown in this second part. Sintered specimens were analyzed by Raman spectroscopy, scanning electron microscopy and impedance spectroscopy. The main results show that both types of solid solutions may attain a high densification (> 95% of the theoretical density for sintering temperatures lower than 0.45 T F (T F = melting temperature. The rate of grain growth is governed by the stabilizing cation and is faster for Ce-TZP than for Y-TZP. Raman spectra exhibit the six characteristic bands of the tetragonal phase for both specimens. Impedance spectroscopy results for Y-TZP do not differ from those obtained for nanophase ceramics. A reduction in the extrinsic conductivity due to the high purity of the crystallized precursor was observed for Ce-TZP specimens.

    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)

    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.

  10. Technical Information on the Carbonation of the EBR-II Reactor, Summary Report Part 2: Application to EBR-II Primary Sodium System and Related Systems

    Energy Technology Data Exchange (ETDEWEB)

    2006-03-01

    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 decontamination and decomissioning 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 humidifed 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, USA. This report is Part 2 of a two-part report. This second report provides a supplement to the first report and describes the application of the humdidified carbon dioxide technique ("carbonation") to the EBR-II primary tank, primary cover gas systems, and the intermediate heat exchanger. Future treatment plans are also provided.

    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.

    Well leak tests and a cavern pressure were conducted in June through December 1981, and are described in Part I. The tests did not indicate conclusively that there was no leakage from the cavern, but the data indicate that cavern structural failure during oil storage is unlikely. The test results indicated that retesting and well workover were desirable prior to making a decision on the cavern use. Well leak tests were conducted in March through May 1982, and are described in Part II. The tests indicated that there was no significant leakage from wells 2 and 4 but that the leakage from wells 2A and 5 exceeded the DOE criterion. Because of the proximity of cavern 2-4-5 to the edge of the salt, this cavern should be considered for only one fill/withdrawal cycle prior to extensive reevaluation. 57 figures, 17 tables.

    Tiller, William A

    2010-04-01

    In Part I of this pair of articles, the fundamental experimental observations and theoretical perspectives were provided for one to understand the key differences between our normal, uncoupled state of physical reality and the human consciousness-induced coupled state of physical reality. Here in Part II, the thermodynamics of complementary and alternative medicine, which deals with the partially coupled state of physical reality, is explored via the use of five different foci of relevance to today's science and medicine: (1) homeopathy; (2) the placebo effect; (3) long-range, room temperature, macroscopic size-scale, information entanglement; (4) an explanation for dark matter/energy plus human levitation possibility; and (5) electrodermal diagnostic devices. The purpose of this pair of articles is to clearly differentiate the use and limitations of uncoupled state physics in both nature and today's orthodox medicine from coupled state physics in tomorrow's complementary and alternative medicine.

    Leon Sarmiento, Fidias E.

    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.

  7. Further considerations on the evaluation of potential reduced-risk tobacco products. Part II: Re-assessment of a heuristic using the CPS-II database.

    Murrelle, Lenn; Coggins, Christopher R E; Gennings, Chris; Carchman, Richard A; Lee, Peter N; Zedler, Barbara K; Heidbreder, Christian

    2010-06-01

    In a previous analysis (see Part I) we proposed a heuristic for assessing the efficacy of potential reduced-risk tobacco products (PRRPs) on lung cancer (LC) rates, using smoking cessation data published in a report from the Iowa Women's Health Study (IWHS) as a basis for sample size estimates. In this study, an additional analysis was performed using cessation data from the much larger Cancer Prevention Study II (CPS-II), which also provides data on different durations of cessation. Statistical methods were used to assess whether smokers switching to a PRRP would reduce their risk of LC. Furthermore, non-inferiority tests compared the LC risk in switchers to that in smokers who had quit smoking. The present work shows that similar sample size estimates were obtained whether the analysis was based on the IWHS or the CPS-II data sets, suggesting that the heuristic may be generally applicable to prospective real-life studies to evaluate PRRPs. Non-inferiority testing of switchers compared with quitters required approximately 10-fold more subjects than did superiority testing of switchers compared with smokers. Altogether, these estimates indicate that it is feasible, in terms of study duration and sample size, to clinically assess the LC risk-reducing potential of a PRRP. (c) 2009 Elsevier Inc.

    2016-04-01

    In October 2013 the second Meteor Crater Experiment (METCRAX II) took place at the Barringer Meteorite Crater (aka Meteor Crater) in north central Arizona, USA. Downslope-windstorm-type flows (DWF), the main research objective of METCRAX II, were measured by a comprehensive set of meteorological sensors deployed in and around the crater. During two weeks of METCRAX II five infrared (IR) time lapse cameras (VarioCAM® hr research & VarioCAM® High Definition, InfraTec) were installed at various locations on the crater rim to record high-resolution images of the surface temperatures within the crater from different viewpoints. Changes of surface temperature are indicative of air temperature changes induced by flow dynamics inside the crater, including the DWF. By correlating thermal IR surface temperature data with meteorological sensor data during intensive observational periods the applicability of the IR method of representing flow dynamics can be assessed. We present evaluation results and draw conclusions relative to the application of this method for observing air flow dynamics in the crater. In addition we show the potential of the IR method for METCRAX II in 1) visualizing airflow processes to improve understanding of these flows, and 2) analyzing cold-air flows and cold-air pooling.

    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.

    Full Text Available En esta ponencia, introducimos una medida continua y simple de crédito, que asocia a cada empresa un parámetro de riesgo relacionado con la intensidad del incumplimiento neutral respecto al riesgo por parte de la empresa. Se pueden calcular estos parámetros por medio de los precios de las obligaciones cotizadas y que permiten asignar tarificaciones del crédito mucho más ajustadas que las ofrecidas por diferentes agencias de tarificación. Estimamos las medidas de riesgo en una base diaria, para una determinada muestra de empresas y las comparamos con las tarificaciones correspondientes ofrecidas por Moody y la distancia para medidas de incumplimiento calculadas usando el modelo de Merton (1974. Las tres medidas agrupan la muestra de empresas en varias clases de riesgo, de un modo similar, pero lejos de ser idénticas, posiblemente reflejan los diferentes horizontes de predicción de los modelos. Entre las tres medidas, la correlación de más alto rango se encuentra entre nuestra medida continua y las tarificaciones de Moody. Se pueden utilizar las técnicas que proponemos aquí para obtener la distribución total de las intensidades del incumplimiento neutrales respecto al riesgo e inter-temporales, que son útiles para las estimaciones del tiempo de incumplimiento, así como para valorar derivados de crédito.

Esta importancia va siendo reconocida cada día más, a pesar de ser (o de haber sido el de la corrosión uno de los temas menos familiares en el ámbito de la construcción. La razón estriba en la fuerza de los hechos, y se manifiesta con claridad en las tareas encomendadas y en los problemas presentados a los laboratorios de investigación y ensayos de materiales. La corrosión es un fenómeno fisicoquímico que cae dentro del dominio de la ELECTROQUIMICA y que debe estudiarse y enjuiciarse con arreglo a las leyes fundamentales de esta disciplina. Lo mismo cabe decir por lo que respecta a los métodos de "protección" contra la corrosión. La corrosión es un "riesgo" aleatorio que se corre y contra el que hay que prevenirse mediante un "seguro", representado por dichas medidas de protección. El remedio "más fácil" desde un punto de vista técnico, y "más barato" desde un punto de vista "económico", es siempre de carácter "preventivo" antes que "curativo", es decir, es el tomado ya en la etapa de proyecto de la obra o estructura de que se trate. En el caso del hormigón, la mejor protección de las armaduras la da, en primer lugar, la aplicación de un "código de buena práctica" a la elaboración del material y a la ejecución de la obra, y, en segundo lugar, la observancia de los más elementales principios de la Electroquímica en el aspecto de la corrosión. La utilización de aditivos acelerantes de fraguado y endurecimiento con naturaleza "clorurada" y el estado de "tensión" de las armaduras son aspectos que merecen especial consideración, así como las posibles acciones electroquímicas debidas a "corrientes vagabundas" a trav

    2007-06-01

    The green machining process is virtually a must if the powder metallurgy (PM) industries are to solve the lower machining performances associated with PM components. This process is known for lowering the rate of tool wear. Recent improvements in binder/lubricant technologies have led to high-green-strength systems that enable green machining. Combined with the optimized cutting parameters determined in Part I of the study, the green machining of PM components seems to be a viable process for fabricating high performance parts on large scale and complete other shaping processes. This second part of our study presents a comparison between the machining behaviors and the sintered properties of components machined prior to or after sintering. The results show that the radial crush strength measured on rings machined in their green state is equal to that of parts machined after sintering.

    1976-04-09

    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.

    Full Text Available Cada entidad bancaria tiene sus propios parámetros de evaluación de clientes y aplica sus propios métodos para hacerlo. Esto forma parte de su política de administración de riesgos. El análisis del comportamiento de la cuenta corriente de cada cliente es de suma importancia en este caso, ya que describe la conducta del cliente en relación a sus deudas y ayuda a evaluar los riesgos que el banco asume. A su vez, este análisis permite la descripción de la evolución de los riesgos mediante el hallazgo de un patrón de conducta de cada cliente. Una vez descripta esta evolución, la entidad podrá definir su política crediticia de corto plazo en cuenta corriente, pudiendo hacer un seguimiento de las cuentas que entran en zonas que el banco evaluaría como indeseables. En el presente trabajo se desarrolla, mediante un modelo simple con datos generados en forma aleatoria, una aplicación referida a estos métodos de evaluación. Se presenta, fundamentalmente, el método de Fuzzy Clustering, utilizando los programas SPSS® y R para desarrollar los cálculos.

  4. Global optimization of truss topology with discrete bar areas-Part II: Implementation and numerical results

    -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...... we use the theory developed in Part I to design a convergent nonlinear branch-and-bound method tailored to solve large-scale instances of the original discrete problem. The problem formulation and the needed theoretical results from Part I are repeated such that this paper is self-contained. We focus...... 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...

    Full Text Available Los estudios sobre la vulnerabilidad social han ampliado la gestión de los riesgos naturales tradicionalmente direccionada a la amenaza natural y soluciones tecnológicas. Sin embargo la visión dominante se mantiene hegemónica sin un análisis adecuado de las causas que originan vulnerabilidad social.Este artículo propone un nuevo argumento, organizado en torno al concepto de la incuestionabilidad del riesgo, entendido como la incapacidad cultural y política de objetar el modelo socioeconómico imperante en donde residen las causas de fondo productoras de riesgo. Para concretar el concepto, a modo de ejemplo, se analizan el Plan de Actuación Municipal frente al Riesgo Sísmico de la ciudad de Torrevieja.

  7. A Quantum Computational Semantics for Epistemic Logical Operators. Part II: Semantics

    Science.gov (United States)

    Beltrametti, Enrico; Dalla Chiara, Maria Luisa; Giuntini, Roberto; Leporini, Roberto; Sergioli, Giuseppe

    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.

  15. Elastic and Piezoelectric Properties of Boron Nitride Nanotube Composites. Part II; Finite Element Model

    Science.gov (United States)

    Kim, H. Alicia; Hardie, Robert; Yamakov, Vesselin; Park, Cheol

    2015-01-01

    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.

  4. Limited Feedback Multi-Antenna Quantization Codebook Design-Part II: Multiuser Channels

    CERN Document Server

    Khoshnevis, Behrouz

    2010-01-01

    This is the second part of a two-part paper on optimal design of limited feedback single-user and multiuser spatial multiplexing systems. The first part of the paper studies the single-user system and this part addresses the multiuser case. The problem is cast in form of minimizing the average transmission power at the base station subject to the outage probability constraints at the users' side. The optimization is over the power control function at the base station as well as the users' channel quantization codebooks. The base station has $M$ antennas and serves $M$ single-antenna users, which share a common feedback link with a total rate of $B$ bits per fading block. We first fix the quantization codebooks and study the optimal power control problem which leads to an upper bound for the average transmission sum power. The upper bound solution is then used to optimize the quantization codebooks and to derive the optimal bit allocation laws in the asymptotic regime of $B\\to\\infty$. The paper shows that for ...

  19. On the whole spectrum of Timoshenko beams. Part II: further applications

    Science.gov (United States)

    Cazzani, Antonio; Stochino, Flavio; Turco, Emilio

    2016-04-01

    The problem of free vibrations of the Timoshenko beam model has been addressed in the first part of this paper. A careful analysis of the governing equations has shown that the vibration spectrum consists of two parts, separated by a transition frequency, which, depending on the applied boundary conditions, might be itself part of the spectrum. Here, as an extension, the case of a doubly clamped beam is considered. For both parts of the spectrum, the values of natural frequencies are computed and the expressions of eigenmodes are provided: this allows to acknowledge that the nature of vibration modes changes when moving across the transition frequency. This case is a meaningful example of more general ones, where the wave-numbers equation cannot be written in a factorized form and hence must be solved by general root-finding methods for nonlinear transcendental equations. These theoretical results can be used as further benchmarks for assessing the correctness of the numerical values provided by several numerical techniques, e.g. finite element models.

  20. The decision to extract: part II. Analysis of clinicians' stated reasons for extraction.

    Science.gov (United States)

    Baumrind, S; Korn, E L; Boyd, R L; Maxwell, R

    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

  4. On the Effects of Frequency Scaling over Capacity Scaling in Underwater Networks— Part II: Dense Network Model

    DEFF Research Database (Denmark)

    2013-01-01

    This is the second in a two-part series of papers on information-theoretic capacity scaling laws for an underwater acoustic network. Part II focuses on a dense network scenario, where nodes are deployed in a unit area. By deriving a cut-set upper bound on the capacity scaling, we first show...... that there exists either a bandwidth or power limitation, or both, according to the operating regimes (i.e., path-loss attenuation regimes), thus yielding the upper bound that follows three fundamentally different information transfer arguments. In addition, an achievability result based on the multi-hop (MH......) transmission is presented for dense networks. MH is shown to guarantee the order optimality under certain operating regimes. More specifically, it turns out that scaling the carrier frequency faster than or as is instrumental towards achieving the order optimality of the MH protocol....

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.

    Full Text Available The paper examines the dynamic response of a two-bogie vehicle to the symmetrical and antisymmetrical excitations, due to bounce and pitch of the axles’ planes, derived from the track vertical irregularities. Part I introduced the theoretical model and the response functions of the vehicle, as well as the theoretical elements required for the analysis of the dynamic response of the vehicle to the track stochastic irregularities. Part II comprises the results of the numerical analysis of the vehicle dynamic response in three reference points of the carbody, based on which a series of properties of the vertical vibrations behaviour of the railway vehicle is pointed out at. The excitation modes that trigger the carbody response in its reference points are identified. Hence, the influence of the geometrical filtering effect of the excitation modes upon the ride quality and ride comfort is established.

  7. The effect of Reynolds number on inertial particle dynamics in isotropic turbulence. Part II: Simulations with gravitational effects

    CERN Document Server

    Ireland, Peter J; Collins, Lance R

    2015-01-01

    In Part I of this study, we analyzed the motion of inertial particles in isotropic turbulence in the absence of gravity using direct numerical simulation (DNS). Here, in Part II, we introduce gravity and study its effect over a wide range of flow Reynolds numbers, Froude numbers, and particle Stokes numbers. We see that gravity causes particles to sample the flow more uniformly and reduces the time particles can spend interacting with the underlying turbulence. We also find that gravity tends to increase inertial particle accelerations, and we introduce a model to explain that effect. We then analyze the particle relative velocities and radial distribution functions (RDFs), which are generally seen to be independent of Reynolds number for low and moderate Kolmogorov-scale Stokes numbers $St$. We see that gravity causes particle relative velocities to decrease, and that the relative velocities have higher scaling exponents with gravity. We observe that gravity has a non-trivial effect on clustering, acting to ...

    Abnormal root canal morphologies of third molars can be diagnostically and technically challenging during root canal treatment. The aim of this retrospective study was to investigate the root and canal morphology of mandibular third molars in Central India population by using Cone Beam Computed Tomography (CBCT) analysis. CBCT images of 171 mandibular third molars were observed and data regarding number of roots, number of canals, Vertucci's classification in each root, prevalence of C shaped canal, gender and topographical relation of morphology in mandibular third molar was statistically evaluated. Majority of mandibular third molars had two roots (84.2%) and three canals (64.3%). Most mesial root had Vertucci Type II (55.6%) and Vertucci Type IV (22.2%), distal root had Type I canals (87.5%). Over all prevalence of C shaped canals in mandibular third molars was 9.4%. There was a high prevalence of two rooted mandibular third molars with three canals.

  10. Part I: In-situ fluorometric quantification of microalgal neutral lipids. Part II: Thermal degradation behavior of investment casting polymer patterns

    Science.gov (United States)

    Zhao, Hongfang

    Research described in this dissertation covers two topics. Part-I is focused on in-situ determination of neutral lipid content of microalgae using a lipophilic fluorescent dye. The traditional Nile red stain-based method for detecting microalgal intracellular lipids is limited due to varying composition and thickness of rigid cell walls. In this study, the addition of dilute acid and heating of solution, were found to greatly enhance staining efficiency of Nile red for microalgal species evaluated. Oil-in-water (O/W) microemulsion stabilized by a non-ionic surfactant was employed as a pseudo-standard that mimics lipid-bearing microalgal cells suspended in water. The average neutral lipid contents determined were very close to the results obtained by traditional gravimetric method and solid phase extraction. Part II of the dissertation explores thermo-physico-chemical properties of polymeric pattern materials, including expanded polystyrene (EPS) foam, polyurethane foam, and epoxy stereolithography (SLA) patterns, that are used in investment casting. Density, elastic modulus, expansion coefficient, thermal degradation behavior, etc. were experimentally investigated for their effects on metal casting quality. The reduction in toxic hydrogen cyanide (HCN) generated during thermal decomposition of polyurethane pattern was achieved by increasing either oxidant level or residence time in heated zone. Thermal degradation kinetics of the pattern materials were examined with a thermogravimetric analysis and activation energies were determined by Kissinger and Flynn-Wall-Ozawa methods.

    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.)

    Intraoperative application of tomographic imaging techniques provides a means of visual servoing for objects beneath the surface of organs. The focus of this survey is on therapeutic and diagnostic medical applications where tomographic imaging is used in visual servoing. To this end, a comprehensive search of the electronic databases was completed for the period 2000-2013. Existing techniques and products are categorized and studied, based on the imaging modality and their medical applications. This part complements Part I of the survey, which covers visual servoing techniques using endoscopic imaging and direct vision. The main challenges in using visual servoing based on tomographic images have been identified. 'Supervised automation of medical robotics' is found to be a major trend in this field and ultrasound is the most commonly used tomographic modality for visual servoing.

    Implementing real-time product quality control meets one or both of the key goals outlined in FDA's PAT guidance: "variability is managed by the process" and "product quality attributes can be accurately and reliably predicted over the design space established for materials used, process parameters, manufacturing, environmental, and other conditions." The first part of the paper presented an overview of PAT concepts and applications in the areas of upstream and downstream processing. In this second part, we present principles and case studies to illustrate implementation of PAT for drug product manufacturing, rapid microbiology, and chemometrics. We further present our thoughts on how PAT will be applied to biotech processes going forward. The role of PAT as an enabling component of the Quality by Design framework is highlighted. Integration of PAT with the principles stated in the ICH Q8, Q9, and Q10 guidance documents is also discussed.

  14. Communication in a Poisson Field of Interferers -- Part II: Channel Capacity and Interference Spectrum

    CERN Document Server

    Pinto, Pedro C

    2010-01-01

    In Part I of this paper, we presented a mathematical model for communication subject to both network interference and noise, where the interferers are scattered according to a spatial Poisson process, and are operating asynchronously in a wireless environment subject to path loss, shadowing, and multipath fading. We determined the distribution of the aggregate interference and the error performance of the link. In this second part, we characterize the capacity of the link subject to both network interference and noise. Then, we put forth the concept of spectral outage probability (SOP), a new characterization of the aggregate radio-frequency emission generated by communicating nodes in a wireless network. We present some applications of the SOP, namely the establishment of spectral regulations and the design of covert military networks. The proposed framework captures all the essential physical parameters that affect the aggregate network emission, yet is simple enough to provide insights that may be of value...

    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.

    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.

  19. Probability calculus for quantitative HREM. Part II: entropy and likelihood concepts.

    Science.gov (United States)

    Möbus, G

    2000-12-01

    The technique of extracting atomic coordinates from HREM images by R-factor refinement via iterative simulation and global optimisation is described in the context of probability density estimations for unknown parameters. In the second part of this two-part paper we discuss in comparison maximum likelihood and maximum entropy techniques with respect to their suitability of application within HREM. We outline practical difficulties of likelihood estimation and present a synthesis of two point-cloud techniques as a recommendable solution. This R-factor refinement with independent Monte-Carlo error calibration is a highly versatile method which allows adaptation to the special needs of HREM. Unlike simple text-book estimation methods, there is no requirement here on the noise being additive, uncorrelated, or Gaussian. It also becomes possible to account for a subset of systematic errors.

  20. '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.

  1. HIERARCHICAL METHODOLOGY FOR MODELING HYDROGEN STORAGE SYSTEMS PART II: DETAILED MODELS

    Energy Technology Data Exchange (ETDEWEB)

    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.

    In the first part of the article, published in the previous issue of this journal, on the basis of studying features of the process a physical and mathematical model is presented of carbide formation during heat-resistant steel vacuum carburizing based on the example of VKS-5. In the second part of this article on the basis of analyzing the calculation model physical features are presented for formation of cementite type carbide phase taking account of steel VKS-5 alloying with chromium and nickel, and also temperature. Simultaneously, features of special molybdenum, tungsten, vanadium and niobium carbide formation are considered. The expediency of increasing chromium content in a new generation of heat-resistant steels alloyed with nickel is substantiated.

  3. [Inner Ear Hearing Loss Part II: Sudden Sensorineural Hearing Loss, Therapeutic Options].

    Hesse, Gerhard

    2016-07-01

    The great majority of hearing disorders generates from pathologies in the inner ear, mainly the outer hair cells, as mentioned in the first part of this review. Very often, however, hearing loss appears suddenly and even without external causes like noise exposure. This sudden hearing loss is mostly unilateral, recovers very often spontaneously and should be treated, if persisting. Only in this acute stage there are therapeutic options available. If the inner ear hearing loss is chronic there is no curative therapy, an effective management of the hearing disorder is only possible through rehabilitation. This is due to the fact, that hair cells of all mammals, incl. humans, have no regenerative capacity and neither pharmaceutic agents nor other means can induce regeneration and recovery of hair cells. Even a gen-therapy is not available yet. In the second part of this review the main focus lies in sudden hearing loss and general therapeutic options for inner ear hearing loss.

  4. Autonomy, consent and responsibility. Part II. Informed consent in medical care and in the law.

    Mellado, J M

    Legal recognition of patient's rights aspired to change clinical relationship and medical lex artis. However, its implementation has been hampered by the scarcity of resources and the abundance of regulations. For several years, autonomy, consent, and responsibility have formed one of the backbones of the medical profession. However, they have sparked controversy and professional discomfort. In the first part of this article, we examine the conceptual and regulatory limitations of the principle of autonomy as the basis of informed consent. We approach the subject from philosophical, historical, legal, bioethical, deontological, and professional standpoints. In the second part, we cover the viability of informed consent in health care and its relationship with legal responsibility. Copyright © 2016 SERAM. Publicado por Elsevier España, S.L.U.

    2016-05-01

    Full Text Available A computer assisted procedure for the cinematic analysis of the mechanism of a cam is essential in making a certain type of research operations. They mainly refer to the optimization of operations running on specific machinery, or to the re-design of the mechanism, in order to make the mechanism digital. This analysis seems even more important, when we consider the fact that most of the machines used in shoe industry nowadays use a cam mechanism. The paper is devided in two parts. In first part, it is elaborated a method of finding of a function G(x, belonging to a Fourier series, which approximates the numerical values {xi, yi}, with the biggest accuracy. Finding the function that approximates the most accurately the data set, for the position parameters of the follower S(ω, ( will lead to a complete kinematic and dynamic analysis of the cam mechanism. These values repeat with T = 2π period. In second part, the method is tasted using MatCAD work sessions which allow a numerical and graphical analysis of the mathematical relations involved, in order to test the reability of the method. The set of experimental data are resulted after measuring a cam mechanism of a machine used in shoemaking.

    2011-01-01

    Hemodialysis (HD) patients are particularly predisposed to infections. It seems that the HD procedure per se as well as disturbances in both innate and adaptive immunity significantly contribute to this susceptibility. Infections are the major cause of morbidity and the second cause of death following cardiovascular events in HD patients. Episodes of bacteremia and pneumonia account for the majority of severe infections in this population. In addition to these bacterial infections another common problem in HD units is the blood transmitted viral infections, particularly infections caused by hepatitis B virus, hepatitis C virus and Human immunodeficiency virus. A number of safety concerns exist for limiting the spread of these viral infections among HD patients and the staff of the unit. The aim of the present review is to present in a concise albeit practical form the difficult aspect of infections in HD. For practical reasons the review is separated in two parts. The previous first part covered bacteremia and respiratory infections, while the present second part covers blood transmitted viral infections. PMID:22110292

    2008-01-01

    Full Text Available This is the second part of paper [P. Grabowski, The motion planning problem and exponential stabilization of a heavy chain. Part I, to appear in International Journal of Control], where a model of a heavy chain system with a punctual load (tip mass in the form of a system of partial differential equations was interpreted as an abstract semigroup system and then analysed on a Hilbert state space. In particular, in [P. Grabowski, The motion planning problem and exponential stabilization of a heavy chain. Part I, to appear in International Journal of Control] we have formulated the problem of exponential stabilizability of a heavy chain in a given position. It was also shown that the exponential stability can be achieved by applying a stabilizer of the colocated-type. The proof used the method of Lyapunov functionals. In the present paper, we give other two proofs of the exponential stability, which provides an additional intrinsic insight into the exponential stabilizability mechanism. The first proof makes use of some spectral properties of the system. In the second proof, we employ some relationships between exponential stability and exact observability.

    2010-03-01

    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.

    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.

    2003-01-01

    Full Text Available El riesgo de la asistencia sanitaria en general, especialmente el motivado por los errores de medicación, es un grave problema con gran repercusión humana, asistencial y económica, que está siendo abordado de forma prioritaria por las autoridades sanitarias de algunos países. Sin embargo, en España no se ha tomado conciencia de su trascendencia, aunque su magnitud en nuestro país sea similar a la de los países de su entorno.

    Full Text Available El riesgo de la asistencia sanitaria en general, especialmente el motivado por los errores de medicación, es un grave problema con gran repercusión humana, asistencial y económica, que está siendo abordado de forma prioritaria por las autoridades sanitarias de algunos países. Sin embargo, en España no se ha tomado conciencia de su trascendencia, aunque su magnitud en nuestro país sea similar a la de los países de su entorno.

    This report describes two topics related to the development of polymer electrolyte fuel cells. The first part deals with specific materials science oriented aspects of this technology and progress achieved within this project, namely (i) the fundamental electrochemistry of platinum in contact to a solid electrolyte, including the aspect of reducing the platinum content to allow a low cost solution for membrane-electrode-assemblies and the characterization of ageing processes, and (ii) the development of platinum-free or platinum-low catalysts on the basis of oxides for the oxygen reduction reaction. (iii) The development of low cost proton-conducting polymer membranes on the basis of the radiation grafting process, followed by sulfonation to introduce proton conductivity. The second part of the report describes the progress of the development of in situ characterization methods for polymer electrolyte fuel cells. Neutron radiography as method to visualize and quantify liquid water in polymer electrolyte fuel cells was further improved. For the first time, results of a combination of neutron radiography and locally resolved impedance measurements could be achieved and are presented. Further, for the first time a pseudo-reference electrode is introduced into a polymer electrolyte fuel cell, which allows single electrode impedances of anode and cathode. Kinetic data for the hydrogen oxidation and oxygen reduction reaction could be evaluated, respectively. (author)

    Full Text Available Abstract Background In the first part of this study we proposed a new classification approach for spinal deformities (3-DEMO. To be valid, a classification needs to overcome the repeatability issue which is inherent both in the used classificatory system and in the measured object. Aim The aim of this study is to present procedures and results obtained within the repeatability of 3-DEMO classification for scoliosis analysis. Method We acquired the data of 100 pathological and 20 normal spines with an optoelectronic system (AUSCAN and of two dummies with simulated spine deformity. On the obtained 3D reconstruction of the spine, we considered the coronal view with a spinal reference system (Top View and its three related parameters, defined in part I, constituting the 3-DEMO classification. We calculated the repeatability coefficient for the subjects (two acquisitions for each subject with a time interval of 26 ± 12 sec, whereas we evaluated the system measurement error calculating the standard deviation of 50 consecutive acquisitions for each dummy. Results Comparing the results of the two types of acquisition, it emerged that the main part of parameters variability was due to postural adjustments The proportion of agreement for the 3-DEMO parameters gives a k value above 0.8; almost 10% of patients changed classification because of postural adjustments, but none had a "mirror-like" variation nor a change in more of one parameter at a time Repeatability coefficient is lower than the previously calculated normative limits. Discussion The 3-DEMO classification has a high repeatability when evaluated with an optoelectronic system such as the AUSCAN System, whose systematic error is very low. This means that the implied physiological phenomenon is consistent and overcomes the postural variability inherent in the measured object (normal or pathological subject.

  1. Investigation of novel propulsion systems – the exoskeletal engine concept. Part II

    2011-06-01

    Full Text Available The exoskeletal engine represents a relatively new concept in the world of propulsion systems. It is a drum-rotor engine concept in which conventionally heavy shafts and discs are eliminated and replaced by rotating casings that support the blades in span wise compression. Thus the rotating blades are in compression rather than in tension. The resulting open channel at the engine centerline has immense potential for jet noise reduction and can also accommodate an inner combined-cycle thruster such as a ramjet. This is the second part of the article.

    Team projects are an important part of the innovative work done in large organizations. Individuals from various portions of the department or organization are chosen who have different areas of expertise, backgrounds, and personalities. In a properly functioning team, the group decisions made will be superior to those made by any individual on the team. There are many different conversations that are necessary during a team project to make sure that all goes optimally, and this article will focus on communication tips for leaders when starting a team.

  4. Cavity Quantum Electrodynamics in a wide aperture spherical resonator. Part II Vacuum-field atom trapping

    2003-01-01

    We consider the situation where a two-level atom is placed in the vicinity of the center of a spherical cavity with a large numerical aperture. The vacuum field at the center of the cavity is actually equivalent to the one obtained in a microcavity, and both the dissipative and the reactive parts of the atom's spontaneous emission are significantly modified. Using an explicit calculation of the spatial dependence of the radiative relaxation rate and of the associated level shift, we show that for a weakly excitating light field, the atom can be attracted to the center of the cavity by vacuum-induced light shifts.

    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.

    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.

    Full Text Available Research in the field of vehicle routing often focused on finding new ideas and concepts in the development of fast and efficient algorithms for an improved solution process. Early studies introduce static tailor-made strategies, but trends show that algorithms with generic adaptive policies - which emerged in the past years - are more efficient to solve complex vehicle routing problems. In this first part of the survey, we present an overview of recent literature dealing with adaptive or guided search techniques for problems in vehicle routing.

    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.

  12. Inadvertent interchange of electrocardiogram limb lead connections: analysis of predicted consequences part II: double interconnection errors.

    Rowlands, Derek J

    2012-01-01

    Limb lead connection errors are known to be very common in clinical practice. The consequences of all possible single limb lead interconnection errors were analyzed in an earlier publication (J Electrocardiology 2008;41:84-90). With a single limb lead interconnection error, 6 combinations of limb lead connections are possible. Two of these combinations give rise to records in which the limb lead morphology is uninterpretable. Such records show a "flat line" in lead II or III. Three of the errors give rise to records that are fully interpretable once the specific interconnection error has been identified (although one of the errors cannot reliably be recognized in the absence of a previous record for comparison). One of the errors produces no change in the electrocardiogram recording. In all cases, the precordial leads are interpretable, although there are very minor changes in the voltages. This communication predicts the changes in limb lead appearances consequent upon all possible double limb lead interchanges and illustrates these with records electively taken with such double interconnection errors. There are only 3 possible double limb lead interconnection errors. In 2 of the possible combinations, interpretation of the limb leads is impossible, and each of these errors gives rise to a flat line in lead I. In the third combination, the record is fully interpretable once the abnormality has been identified. In all 3 types, the precordial leads are interpretable, although there are very minor changes in the voltages.

    The development of new products of high quality, low unit cost, and short lead time to market are the key elements required for any enterprise to obtain a competitive advantage. This part of the paper presents a methodology to automatically simulate the conceptual design results in the virtual entity form. To the identified basic mechanisms, their kinematic analysis is carried out by matching basic Barranov trusses, and their virtual entities are modeled based on feature-based technique and encapsulated as one design object. Based on the structures of the basic mechanisms and their connections, a space layout to the mechanical system corresponding to the symbolic scheme is then fulfilled. With the preset-assembly approach, all parts in the mechanical system are put onto proper positions where the constraint equations are met according to the space layout results. In this way, the virtual entity assembly model of the mechanical system relative to the symbolic scheme is set up. The approach presented in this paper can not only obtain innovative conceptual conceptual design results, but also can evaluate their performances under 3-D enviroment efficently.

    2009-05-30

    Diminished pain sensitivity in schizophrenic patients has been reported for more than 50 years, however little is known about the substrate and the basic mechanisms underlying altered pain sensitivity in this disease, therefore, relevant animal models are of decisive importance in the study of psychiatric diseases. The authors report a review consisting of two parts focusing on pain sensitivity changes in patients and in different animal models which proved the eligibility as schizophrenia models and pain sensitivities have also been determined. The second part of this article analyzed the results regarding knock out mice as schizophrenia models. These data proved that several genes have significant role in the pathomechanism of schizophrenia; therefore deficiency in one gene does not produce animals showing all signs of this disease. As regards the pain sensitivity changes, only a few data are available with controversial results. Data originated from complex chronic animal models indicate that they might be more adequate methods for studying the mechanisms of schizophrenia including the pain-sensitivity changes.

    Jennie C. I. Tsao

    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.

    2013-01-01

    The analysis of the gamma-ray photons collected by the Fermi Large Area Telescope reveals, after removal of astrophysical background, the existence of an excess towards the Galactic center. This excess peaks around few GeV, and its origin is compatible with the gamma-ray flux originating from Dark Matter annihilation. In this work we take a closer look on this interpretation; we investigate which kind of Dark Matter, and which type of interactions with the Standard Model fields are able to reproduce the observed signal. The structure of the paper is twofold. In the first part, we follow an effective field theory approach considering both fermionic and scalar Dark Matter. The computation of the relic density, the constraint imposed from the null result of direct searches, and the reliability of the effective field theory description allow us to single out only two viable dim-6 operators in the case of fermionic Dark Matter. In the second part, we analyze some concrete models. In particular, we find that the sc...

    Małgorzata, W; Merecz, Dorota; Drabek, Marcin

    2010-01-01

    This is the second part of the publication on approaches to occupational stress prevention and a state of the art in different European countries. In this part, stress prevention within an organization is described and discussed. Although there is no one way of tackling stress at work, some recommendations can be formulated to increase the effectiveness of such interventions. The effective stress reducing programs should be aimed both at changes in the organization itself and empowerment of employees' coping with stress resources. It is also important to take the advantage of wide spectrum of methods and techniques (e.g., work redesign, participation, team work, cognitive behavioral methods, relaxation, etc.) remembering that one size does not fit all. The intervention should be carefully planned and adopted to the various branches, an individual organization or department and should be preceded by the identification of stress risks and risk groups. To have the stress prevention program successfully introduced one should also consider factors which may influence (positively or negatively) the process of program implementation.

    Periodic fever syndromes are a group of diseases characterized by episodes of fever with healthy intervals between febrile episodes. In the first part of this paper, we presented a guideline for approaching patients with periodic fever and reviewed two common disorders with periodic fever in Iranian patients including familial Mediterranean fever (FMF) and periodic fever syndromes except for periodic fever, aphthous stomatitis, pharyngitis, and cervical adenitis (PFAPA). In this part, we review other autoinflammatory disorders including hyper IgD, tumor necrosis factor receptor-associated periodic syndrome (TRAPS), cryopyrin associated periodic syndromes, autoinflammatory bone disorders and some other rare autoinflammatory disorders such as Sweet's and Blau syndromes. In cryopyrin associated periodic syndromes group, we discussed chronic infantile neurologic cutaneous and articular (CINCA) syndrome, Muckle-Wells syndrome and familial cold autoinflammatory syndrome. Autoinflammatory bone disorders are categorized to monogenic disorders such as pyogenic arthritis, pyoderma ;gangraenosum and acne (PAPA) syndrome, the deficiency of interleukine-1 receptor antagonist (DIRA) and Majeed syndrome and polygenic background or sporadic group such as chronic recurrent multifocal osteomyelitis (CRMO) or synovitis, acne, pustulosis, hyperostosis and osteitis (SAPHO) syndrome are classified in sporadic group. Other autoinflammatory syndromes are rare causes of periodic fever in Iranian system registry.

    Bauer, G; Dürr, D

    2010-01-01

    This is the second part of our mathematical survey on the equations of motion of classical absorber electrodynamics. Here we study the equations of Wheeler-Feynman (WF) electrodynamics, which describe the interaction of finitely many charges by both the advanced and retarded Li\\'enard-Wiechert fields. These equations are non-linear and involve retarded as well as advanced arguments and belong to the class of delay (or functional) differential equations. Such delayed arguments do not permit a direct application of standard PDE techniques. We introduce a general strategy to handle existence and uniqueness questions for such functional differential equations. We observe that any WF solution gives rise to a solution to the Maxwell-Lorentz equations without self-interaction (ML-SI), which are a set of non-linear PDEs without delay that have been studied in Part I. In other words, WF solutions are special solutions among all solutions of the ML-SI equations. Hence, WF solutions arise as solutions to the ML-SI equat...
