  1. Clinical librarianship in the UK: temporary trend or permanent profession? Part II: present challenges and future opportunities. (United States)

    Harrison, Janet; Sargeant, Sally J E


    This article is the second part of a two-part series reporting a study of the role of the Clinical Librarian (CL) in the UK. A qualitative method of semi-structured interviews was used to explore in-depth the role of the CL. The interviews provided a rich source of data and give insight into this new and emerging role as practised in the National Health Service (NHS). Similarities and differences are examined between the CL population and reported within themes, specifically: personal qualities and skills required, training for the CLs, marketing the CL service, working in the clinical environment, monitoring and evaluation and the acceptance of the CL in the NHS. A common understanding of the skills and knowledge required to undertake the CL role was shared by the respondents. However, practice differed as this was often dictated by local circumstances. The study confirmed the need for the CLs to work with clinical colleagues in the clinical setting to enhance patient care. The importance of using best evidence to support patient care is a message that is slowly becoming the norm in the NHS and the CL role in this practice is demonstrated by this study.

  2. Stiffnites. Part II

    Directory of Open Access Journals (Sweden)

    Maria Teresa Pareschi


    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.

    Results of experimental studies of the X-pinch since its invention and implementation in 1982 at the Lebedev Physical Institute are presented. The review consists of two parts. The first part briefly outlines the history of creation and studies of X-pinches, describes the diagnostic techniques and devices developed during these studies, and presents the main results obtained in studying the physical processes occurring in the X-pinch. The second part is devoted to the results of detailed studies of the spatial, temporal, and spectral characteristics of the X-pinch hot spot—the region where the highest plasma parameters are achieved and which is a source of X-ray emission with extreme parameters. Some results of X-pinch simulations are also presented.

  6. Revenue cycle management, Part II. (United States)

    Crew, Matt


    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.

  10. Dentists' restorative decision-making and implications for an 'amalgamless' profession. Part 2: a qualitative study. (United States)

    Alexander, G; Hopcraft, M S; Tyas, M J; Wong, R H K


    In some countries the use of amalgam has been restricted, and the dental profession may be forced into using alternatives to amalgam by a combination of public opinion and legislation, including the proposal that the material be 'phased-down'. The limited research that exists as to restorative decision-making is quantitative in nature and focuses on 'when' a restoration is placed. There is little qualitative research exploring 'why' a material is chosen. Purposive sampling of a representative group of dentists registered in Australia was carried out in two phases; initially six interviews followed by a focus group of six different participants who were audio-recorded. Qualitative data were analysed using computer aided qualitative data analysis software. The findings suggest that dentists' restorative decision-making is a complex interplay of factors. These may be categorized as 'clinical', 'knowledge', 'patient', 'practice type', 'biological' and 'environmental'. Use of amalgam is influenced by each of these to varying degrees. Quantitative analysis of the influences on restorative decision-making is recommended. While the potential future 'phase-down' of amalgam as a restorative material was of concern, there was a general sense of resignation or apathy to the matter. The implications for public health authorities, dental organizations and educators are noted. © 2014 Australian Dental Association.

  11. Is keep/refer decision making an integral part of national guidelines for the physiotherapy profession within Europe? A review. (United States)

    Lackenbauer, Wolfgang; Janssen, Jessie; Roddam, Hazel; Selfe, James


    Keep/refer decision as the ability to independently determine whether a patient's condition is suitable for physiotherapy management (keep) or not (refer), is regarded as an core element in the World Confederation of Physical Therapists' (WCPT) Guideline for Standards of Physical Therapy Practice. However, it is currently unknown how individual European countries have implemented this in their national guidelines. To determine if keep/refer decision making abilities are an integral part of national guidelines for the physiotherapy profession of member countries of the European Network of Physiotherapy in Higher Education (ENPHE). A review was performed including medical databases, the grey literature and personal correspondence with professional ENPHE member associations. To gain the information of interest, all eligible documents were reviewed. 11 national guidelines for the physiotherapy profession could be obtained. Two additional member associations use European guidelines as their national ones. Despite the fact that in the WCPT guidelines keep/refer decision making abilities are clearly described as a core element, there exists huge inconsistency as to how various European (with direct and non direct access systems) countries have included them in their national guidelines. Despite the fact that most ENPHE member countries deem a close collaboration between health care professionals important and that physiotherapists should know the limitation of their expertise, keep/refer decision making abilities as explicitly stated in the WCPT guidelines were not included in the majority of guidelines that were reviewed.

  13. Thyroid disorders. Part II: hypothyroidism and thyroiditis. (United States)

    Little, James W


    Part II of the series on thyroid disorders discusses hypothyroidism and thyroiditis that may be found in dental patients. An overview of the conditions is presented. Presenting signs and symptoms, laboratory tests used to diagnose hypothyroidism and thyroiditis, and their medical management is discussed. The dental management of patients with hypothyroidism is discussed in detail. The dentist by detecting the early signs and symptoms of hypothyroidism and thyroiditis can refer the patient for medical diagnosis and treatment and avoid potential complications of treating patients with uncontrolled disease. Patients with thyroiditis may have a short period of being hyperthyroid and it may be best to avoid routine dental treatment during that period. Patients with suppurative thyroiditis should not receive routine dental treatment during the acute stage of the disease. The end stage of Hashimoto's thyroiditis results in hypothyroidism. Central nervous system depressants, sedatives, or narcotic analgesics must be avoided in patients with severe hypothyroidism because significant respiratory depression may occur. In addition, myxedematous coma, particularly in elderly hypothyroid patients, can be precipitated by central nervous system depressants, infection, and possibly stressful dental procedures. In medically well-controlled patients the dental treatment plan is not affected and most dental procedures can be offered to these patients.

    Macik, Maria L; Chaney, Kristin P; Turner, Jacqueline S; Rogers, Kenita S; Scallan, Elizabeth M; Korich, Jodi A; Fowler, Debra; Keefe, Lisa M

    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.

    Although good quality DNA can be recovered from the base of the calamus of freshly sampled feathers, as from other fully keratinized tissues such as nail or hair shaft, the quality and quantity of DNA in the majority of feather structures is much poorer. Little research has been performed...... to characterize the quality of this DNA is, and thus what a researcher might be able to achieve when using feathers as a source of DNA. In this review, we expand on our companion article detailing the quality of DNA in nail and hair, by synthesizing published, and new preliminary genetic data obtained from...... feathers. As with nail and hair, we demonstrate that although DNA can, in general, be recovered from all parts of the feather, the quality of such DNA varies. As such, although one can expect a priori that genetic analyses are possible on the feather, for PCR based analyses, it is extremely difficult...

    Ciszowski, Krzysztof; Mietka-Ciszowska, Aneta


    Fish plays a significant role in human life, mainly as part of a balanced healthy diet and a good source of many of nutrients. However, contact with fish may be harmful or even life-threatening to man. Toxic effects, that fish exerts toward men (ichthyotoxism), result from envenomations by poison. ous fish equipped in venom apparatus (ichthyoacanthotoxism), direct contact with venom produced by skin glandules (ichthyocrinotoxism), or consuming fish containing toxins for nutritional purposes (ichthyosarcotoxism). In the present review, different fish-borne food poisonings are presented including their etiology, pathogenesis, symptomatology and treatment. In fact, the majority of fish poisonings are intoxications with toxins primary produced by bacteria, cyanobacteria and algae. These are consumed and accumulated in the food chain by herbivorous and predatory fish, that in turn may be a cause of poisonings in humans.

  15. The sociogeometry of inequality: Part II (United States)

    Eliazar, Iddo


    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.

    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.

  17. Generic drugs in dermatology: part II. (United States)

    Payette, Michael; Grant-Kels, Jane M


    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 ( as an example and for consistency across all medications discussed herein. Prices included here may not reflect actual retail prices across the United States. Copyright © 2011 American Academy of Dermatology, Inc. Published by Mosby, Inc. All rights reserved.

  18. Society. Part II: moderate to severe psoriasis

    Directory of Open Access Journals (Sweden)

    Jacek Szepietowski


    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.

  19. [Conceptual Development in Cognitive Science. Part II]. (United States)

    Fierro, Marco


    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.

  20. Development of aero-engines, part II

    Energy Technology Data Exchange (ETDEWEB)

    Dehn, K.


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

    As a matter of good business practices, a team of glovebox experts from Los Alamos National Laboratory (LANL) has been assembled to proactively investigate processes and procedures that minimize unplanned breaches in the glovebox, e.g., glove failures. A major part of this effort involves the review of glovebox glove failures that have occurred at the Plutonium Facility and at the Chemical and Metallurgy Research Facility. Information dating back to 1993 has been compiled from formal records. This data has been combined with information obtained from a baseline inventory of about 9,000 glovebox gloves. The key attributes tracked include those related to location, the glovebox glove, type and location of breaches, the worker, and the consequences resulting from breaches. This glovebox glove failure analysis yielded results in the areas of the ease of collecting this type of data, the causes of most glove failures that have occurred, the effectiveness of current controls, and recommendations to improve hazard control systems. As expected, a significant number of breaches involve high-risk operations such as grinding, hammering, using sharps (especially screwdrivers), and assembling equipment. Surprisingly, tasks such as the movement of equipment and material between gloveboxes and the opening of cans are also major contributions of breaches. Almost half the gloves fail within a year of their install date. The greatest consequence for over 90% of glovebox glove failures is alpha contamination of protective clothing. Personnel self-monitoring at the gloveboxes continues to be the most effective way of detecting glovebox glove failures. Glove failures from these tasks can be reduced through changes in procedures and the design of remote-handling apparatus. The Nuclear Materials Technology Division management uses this information to improve hazard control systems to reduce the number of unplanned breaches in the glovebox further. As a result, excursions of contaminants

    Aspectos Clínicos

    I. Diagnóstico de los Apudomas
    En este apartado describiremos algunos de los aspectos más relevantes en cuanto al diagnóstico clínico, paraclínico y anatomopatológico de los apudomas conocidos en el páncreas, basándonos en algunas casuísticas nacionales y extranjeras.

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

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

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

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

    A diferencia de los gastrinomas, estos tumores rara vez se asocian con la adenomatosis múltiple endocrina (MEA: probablemente est

  8. [Epidemiological study on alcohol consumption and agricultural profession-related injuries among minority residents from the northern parts of China]. (United States)

    Wang, Li-min; Sun, Yao-wu; Han, Yun-feng; Xiang, Huiyun; Stallones, Lorann; Xue, Hai-feng; Cheng, Yu; Li, Sheng-san


    To understand the incidence rates of agricultural profession-related injuries and the relationship to alcohol consumption. A multistage sample of 2366 villagers was selected from Minority Nationality Villages, Heilongjiang province. Face-to-face interviews were conducted by trained interviewers during May 2008. 2198 (92.9%) of the eligible questionnaires were available. Incidence rate of agricultural profession-related injury rate was 11.8% (260/2198) from May 2007 to April 2008. Higher proportions of injuries were seen for males, 30 - 49 year olds, farmers and among those people working on farms for 10 years or more, smoking during farm work, with sleeping disorder, using motor vehicles, and those using agricultural machinery. Rate of alcohol drinking was 29.1% (640/2198) in the month prior to the investigation. Results from logistic regression models showed that alcohol consumption patterns and other alcohol-related behavior were examined in separate logistic models because of collinearity by controlling the variables that were associated with agricultural profession-related injury including sex, age, years of farm work, driving a motor vehicle, and agricultural machinery use etc. In each model, the reference group was those villagers who did not drink in the past month. The odds of injury among villagers with history of past month drinking, who drank distilled spirits, and alcohol drinking at breakfast and lunch were 1.80 (95%CI: 1.24 - 2.62), 2.09 (95%CI: 1.38 - 3.15), 2.15(95%CI: 1.43 - 3.22) respectively. The odds of agricultural injury also significantly increased with greater average amounts of pure alcohol per day, with increased frequency of drinking per week, and reported years of drinking. Intervention efforts should include increasing awareness about alcohol drinking as a major risk factor causing agricultural injuries as well as controlling alcohol drinking, improving knowledge about driving motor vehicle and using agricultural machinery.

    Khan, Misbah H; Victor, Frank; Rao, Babar; Sadick, Neil S


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

  16. Structure Learning and Statistical Estimation in Distribution Networks - Part II

    Energy Technology Data Exchange (ETDEWEB)

    Deka, Deepjyoti [Univ. of Texas, Austin, TX (United States); Backhaus, Scott N. [Los Alamos National Lab. (LANL), Los Alamos, NM (United States); Chertkov, Michael [Los Alamos National Lab. (LANL), Los Alamos, NM (United States)


    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.

    To update the themes of endoscopic and surgical treatment of Gastroesophageal Reflux Disease (GERD) from the Mexican Consensus published in 2002. Part I of the 2011 Consensus dealt with the general concepts, diagnosis, and medical treatment of this disease. Part II covers the topics of the endoscopic and surgical treatment of GERD. In this second part, an expert in endoscopy and an expert in GERD surgery, along with the three general coordinators of the consensus, carried out an extensive bibliographic review using the Embase, Cochrane, and Medline databases. Statements referring to the main aspects of endoscopic and surgical treatment of this disease were elaborated and submitted to specialists for their consideration and vote, utilizing the modified Delphi method. The statements were accepted into the consensus if the level of agreement was 67% or higher. Twenty-five statements corresponding to the endoscopic and surgical treatment of GERD resulted from the voting process, and they are presented herein as Part II of the consensus. The majority of the statements had an average level of agreement approaching 90%. Currently, endoscopic treatment of GERD should not be regarded as an option, given that the clinical results at 3 and 5 years have not demonstrated durability or sustained symptom remission. The surgical indications for GERD are well established; only those patients meeting the full criteria should be candidates and their surgery should be performed by experts.

  18. PREREM: an interactive data preprocessing code for INREM II. Part I: user's manual. Part II: code structure

    Energy Technology Data Exchange (ETDEWEB)

    Ryan, M.T.; Fields, D.E.


    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.

  19. Blade System Design Study. Part II, final project report (GEC).

    Energy Technology Data Exchange (ETDEWEB)

    Griffin, Dayton A. (DNV Global Energy Concepts Inc., Seattle, WA)


    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

  20. Thanks, but no thanks: how denial of osteopathic service in World War I and World War II shaped the profession. (United States)

    Silver, Shawn A


    Osteopathic physicians were denied the same rights and privileges that were granted to allopathic physicians by the US government regarding voluntary and compulsory service in World War I and World War II. Even after changes to the examination process allowed osteopathic physicians to take the examinations required to obtain commission as a physician in the army, osteopathic physicians' service was still rejected. The US government's decision to ban DOs from serving in the war was a blessing in disguise that led to tremendous changes in osteopathic medicine, education, and public acceptance of osteopathic physicians. Using primary documents from military officials, congressional hearings, and archived publications of the American Osteopathic Association, the author recounts the battle osteopathic physicians fought to serve their country during war and the challenges they faced while obtaining both legal and social equality in the eyes of the government and the public.

  1. Without Distinguishing Color or Profession: Culture, Vatican II and the Long-Term Development of Credit Institutions in Bolivia

    Directory of Open Access Journals (Sweden)

    Brian Norris


    Full Text Available By the late 20th and early 21st century, credit institutions in Bolivia had become more complex, resilient and popular that at any time previously in its history. Traditional economics analyses emphasize incentives created by laws such as those promulgated by the Kemmerer mission in Bolivia in the 1920s and 30s, or material factors, such as transportation costs. Yet neither of these explanations offers a compelling explanation for the magnitude of the flourishing of popular and complex credit institutions in Bolivia after the 1960s. Cultural changes, however, might offer a compelling complement to legal and material explanations of credit development. Vatican II represented an important mass change in Bolivian culture, and institutions associated with these reforms ushered in a new era of credit institution development in the country. A finales del siglo XX y comienzos del XXI, las instituciones crediticias en Bolivia se volvieron más complejas, elásticas y populares que en cualquier otro momento de su historia. Los análisis económicos tradicionales ponen de relieve los incentivos creados por leyes como las promulgadas por la misión Kemmerer en Bolivia en las décadas de 1920 y 1930, o factores materiales, tales como los costos de transporte. Con todo, ninguna de estas explicaciones ofrece una explicación convincente de la importancia del florecimiento de instituciones crediticias populares y complejas en Bolivia después de la década de 1960.  No obstante, los cambios culturales podrían ofrecer un complemento de peso a las explicaciones legales y materiales del desarrollo del crédito. El Concilio Vaticano II representa un importante cambio en la cultura boliviana, y las instituciones asociadas con sus reformas marcan el comienzo de una nueva era en el desarrollo de la institución crediticia en el país.

  4. Managing the professional nurse. Part II. Applying management theory to the challenges. (United States)

    McClure, M L


    In Part I of this article, the author reviewed the ideas of some of the major administrative thinkers over the past 30 years. Having set the stage with an overview of current thinking in the general area of management theory, the author here examines some of the specific challenges involved in managing the professional nurse. Often, these problems are unique and the management theorists offer only limited help. In other instances, management theory is directly relevant. The author addresses the following four broad categories that are unique to the profession of nursing: nursing as a female profession, professionalism and the lack of it, stress and burnout, and expectancy congruence.

  5. Hysterosalpingographic Appearances of Female Genital Tract Tuberculosis: Part II: Uterus

    Directory of Open Access Journals (Sweden)

    Firoozeh Ahmadi


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

  7. Digital Assays Part II: Digital Protein and Cell Assays. (United States)

    Basu, Amar S


    A digital assay is one in which the sample is partitioned into many containers such that each partition contains a discrete number of biological entities (0, 1, 2, 3, . . .). A powerful technique in the biologist's toolkit, digital assays bring a new level of precision in quantifying nucleic acids, measuring proteins and their enzymatic activity, and probing single-cell genotype and phenotype. Where part I of this review focused on the fundamentals of partitioning and digital PCR, part II turns its attention to digital protein and cell assays. Digital enzyme assays measure the kinetics of single proteins with enzymatic activity. Digital enzyme-linked immunoassays (ELISAs) quantify antigenic proteins with 2 to 3 log lower detection limit than conventional ELISA, making them well suited for low-abundance biomarkers. Digital cell assays probe single-cell genotype and phenotype, including gene expression, intracellular and surface proteins, metabolic activity, cytotoxicity, and transcriptomes (scRNA-seq). These methods exploit partitioning to 1) isolate single cells or proteins, 2) detect their activity via enzymatic amplification, and 3) tag them individually by coencapsulating them with molecular barcodes. When scaled, digital assays reveal stochastic differences between proteins or cells within a population, a key to understanding biological heterogeneity. This review is intended to give a broad perspective to scientists interested in adopting digital assays into their workflows.

  8. Reforming Science Education: Part II. Utilizing Kieran Egan's Educational Metatheory (United States)

    Schulz, Roland M.


    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.

  9. Welfare Professions in Transition

    Directory of Open Access Journals (Sweden)

    Annette Kamp


    Full Text Available Welfare professions constitute one of the backbones in the development of the Nordic welfare states. Working in the public sector was for decades associated with high status; public sector employees were trusted employees. Through their work, they had important responsibilities for the welfare state and its citizens. To provide job security—through employment as officials—was a part of ensuring the stability of the state (Åkerstrøm, 2001, and we saw the establishment of what could be called a public ethos, a special morality aimed at serving the needs of the citizens and the state (Hoggett, 2005. The term welfare professions is widely used, referring to public sector employees in the field of, for example, health, education, care, and social work. So this term covers professionals who work directly in contact with patients, citizens, clients, students, etc. (Brante, 1990; Järvinen & Mik-Meyer, 2012. Along with the development and modernization of the welfare state, a number of new welfare professions, such as pedagogues, social works, physiotherapists, social care assistants, and auxiliary nurses have joined the existing ones like nurses, teachers, psychologists, and physicians. At the same time, however, the public sector has undergone dramatic changes as part of a neoliberal transformation of the welfare state. With the New Public Management (NPM wave from 1980s and onwards efforts to restructure public institutions and introduce market-like relationships between them, to outsource and privatize public services and to transform citizens to customers in a market have prevailed (Busch, 2005; Christensen & Lægreid, 2007; Greve, 2008. Within this reform strategy, welfare professionals are perceived as part of the problem that NPM is created to solve, namely an uncontrollable and wildly growing bureaucracy (Clarke & Newman, 1997 (...

  10. Recovery in soccer : part ii-recovery strategies. (United States)

    Nédélec, Mathieu; McCall, Alan; Carling, Chris; Legall, Franck; Berthoin, Serge; Dupont, Gregory


    In the formerly published part I of this two-part review, we examined fatigue after soccer matchplay and recovery kinetics of physical performance, and cognitive, subjective and biological markers. To reduce the magnitude of fatigue and to accelerate the time to fully recover after completion, several recovery strategies are now used in professional soccer teams. During congested fixture schedules, recovery strategies are highly required to alleviate post-match fatigue, and then to regain performance faster and reduce the risk of injury. Fatigue following competition is multifactorial and mainly related to dehydration, glycogen depletion, muscle damage and mental fatigue. Recovery strategies should consequently be targeted against the major causes of fatigue. Strategies reviewed in part II of this article were nutritional intake, cold water immersion, sleeping, active recovery, stretching, compression garments, massage and electrical stimulation. Some strategies such as hydration, diet and sleep are effective in their ability to counteract the fatigue mechanisms. Providing milk drinks to players at the end of competition and a meal containing high-glycaemic index carbohydrate and protein within the hour following the match are effective in replenishing substrate stores and optimizing muscle-damage repair. Sleep is an essential part of recovery management. Sleep disturbance after a match is common and can negatively impact on the recovery process. Cold water immersion is effective during acute periods of match congestion in order to regain performance levels faster and repress the acute inflammatory process. Scientific evidence for other strategies reviewed in their ability to accelerate the return to the initial level of performance is still lacking. These include active recovery, stretching, compression garments, massage and electrical stimulation. While this does not mean that these strategies do not aid the recovery process, the protocols implemented up until

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

  12. Autism and EMF? Plausibility of a pathophysiological link part II. (United States)

    Herbert, Martha R; Sage, Cindy


    Autism spectrum conditions (ASCs) are defined behaviorally, but they also involve multileveled disturbances of underlying biology that find striking parallels in the physiological impacts of electromagnetic frequency and radiofrequency radiation exposures (EMF/RFR). Part I (Vol 776) of this paper reviewed the critical contributions pathophysiology may make to the etiology, pathogenesis and ongoing generation of behaviors currently defined as being core features of ASCs. We reviewed pathophysiological damage to core cellular processes that are associated both with ASCs and with biological effects of EMF/RFR exposures that contribute to chronically disrupted homeostasis. Many studies of people with ASCs have identified oxidative stress and evidence of free radical damage, cellular stress proteins, and deficiencies of antioxidants such as glutathione. Elevated intracellular calcium in ASCs may be due to genetics or may be downstream of inflammation or environmental exposures. Cell membrane lipids may be peroxidized, mitochondria may be dysfunctional, and various kinds of immune system disturbances are common. Brain oxidative stress and inflammation as well as measures consistent with blood-brain barrier and brain perfusion compromise have been documented. Part II of this paper documents how behaviors in ASCs may emerge from alterations of electrophysiological oscillatory synchronization, how EMF/RFR could contribute to these by de-tuning the organism, and policy implications of these vulnerabilities. It details evidence for mitochondrial dysfunction, immune system dysregulation, neuroinflammation and brain blood flow alterations, altered electrophysiology, disruption of electromagnetic signaling, synchrony, and sensory processing, de-tuning of the brain and organism, with autistic behaviors as emergent properties emanating from this pathophysiology. Changes in brain and autonomic nervous system electrophysiological function and sensory processing predominate, seizures

  13. Practical use of the nursing Code of Ethics: part II. (United States)

    Lachman, Vicki D


    The Code Provisions V through IX focus on a variety of responsibilities for the professional nurse. Provision V spotlights nurses' obligation to the same values and actions for themselves as are espoused in The Code for their patients. Provision VI addresses the responsibility of all nurses to maintain quality patient care, regardless of their roles in the health care system. Meeting professional obligations to maintain and forward the nursing profession can take a variety of forms, as indicated in Provision VII. Provision VIII reviews the macro level of professional nursing responsibility by centering on the issues of world hunger, pollution, and other violations of justice. Finally, Provision IX identifies the importance of involvement in professional associations and their efforts for social reform. The first two provisions of The Code address the boundaries of obligation and dependability (Lachman, 2009), and the last three address the duties outside individual patient experience.

  14. Discovery of Quantum structure and A Theory of Everything Part I and Part II (United States)

    Zhang, Meggie


    (Part I) During my research I discovered logical errors in the logic of science and in mathematics. These errors caused scientists missed out important information when interpreting data. This led me to revisit the method of science and the existing results and able to find new information, which lead to the discovery of photon's structure. A ``particle collision illumination'' experiment then provided direct evidence supported the structure. Analysis of the properties of the structure suggested an organized but not-continuous multi-dimension (n-D) space within. Therefore I formed a hypothesis of a not-continuous n-D space structure. In search for evidence, I turned into crystal technology, and found direct evidence supported the hypotesis, then further particle collision found more evidence support this finding. (Part II) Analysis of single electron buildup revealed star and galaxy formation is from a single particle following a predictable pattern. This pattern is also common in matter formation. Analysis of the quantum structure suggested the formation of a larger structure through the space expansion within the structure. Further experiment results support the finding and result revealed the expansion is through space folding. Result also suggested a violation of energy conservation law that energy is created during the formation of matter, and matter itself is moving from a lower energy state to a higher energy state. When putting all information together, I arrived to a theory of everything which gives explanations to all existing phenomenon in the universe including black hole, dark energy, star formation, consciousness.

  15. Psychiatric emergencies (part II): psychiatric disorders coexisting with organic diseases. (United States)

    Testa, A; Giannuzzi, R; Sollazzo, F; Petrongolo, L; Bernardini, L; Dain, S


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

  19. Complexometric determination, Part II: Complexometric determination of Cu2+-ions

    Directory of Open Access Journals (Sweden)

    Rajković Miloš B.


    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.

  8. Supraventricular tachycardia-Part II: History, presentation, mechanism, and treatment. (United States)

    Lee, Ken W; Badhwar, Nitish; Scheinman, Melvin M


    Supraventricular tachycardias (SVTs) affect all age groups and are a source of significant morbidity. They are frequently encountered in otherwise healthy individuals without structural heart disease. Advances in the understanding of their mechanisms and anatomical locations have led to highly effective pharmacologic and nonpharmacologic treatment strategies. Recognition, identification, and differentiation of the various SVTs are of great importance in formulating an effective treatment strategy. Developments over the past four decades have made possible the accurate diagnosis of SVTs, and technological advances have led to ablative cures of most of these arrhythmias. This monograph provides an in-depth discussion of the history, presentation, mechanism, and treatment strategies of the most commonly encountered SVTs. The monograph is divided in two parts. Arrhythmias and related syndromes that are covered in detail in the first part include atrioventricular nodal reentrant tachycardia, Wolf-Parkinson-White syndrome, and atrioventricular reentrant tachycardia. The remaining SVTs are covered in the second part, which is presented here.

    Koča, Jaroslav; Carlsen, Per H. J.


    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.

    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...

  1. Part I. Mechanisms of injury associated with extracorporeal shock wave lithotripsy; Part II. Exsolution of volatiles (United States)

    Howard, Danny Dwayne

    Part I - Shock waves are focused in extracorporeal shock wave lithotripsy (ESWL) machines to strengths sufficient to fracture kidney stones. Substantial side effects-most of them acute-have resulted from this procedure, including injury to soft tissue. The focusing of shock waves through various layers of tissue is a complex process which stimulates many bio-mechano-chemical responses.This thesis presents results of an in vitro study of the initial mechanical stimulus. Planar nitrocellulose membranes of order 10 um thick were used as models of thin tissue structures. Two modes of failure were recorded: Failure due to cavitation collapsing on or near the membranes, and failure induced by altering the structure of shock waves. Tests were done in water at and around F2 to characterize the extent of cavitation damage, and was found to be confined within the focal region, 1.2 cm along the axis of focus.Scattering media were used to simulate the effects of acoustic nonuniformity of tissue and to alter the structure of focusing shock waves. 40 um diameter (average) hollow glass spheres were added to ethylene glycol, glycerine and castor oil to vary the properties of the scattering media. Multiple layer samples of various types of phantom tissue were tested in degassed castor oil to gauge the validity of the scattering media. The scattering media and tissue samples increased the rise time decreased strain rate in a similar fashion. Membranes were damaged by the decreased strain rate and accumulated effects of the altered structure: After about 20 or so shocks immersed in the scattering media and after about 100 shocks behind the tissue samples. The mode of failure was tearing with multiple tears in some cases from about .1 cm to about 3 cm depending of the number of shocks and membrane thickness.Part II - This work examines the exsolution of volatiles-carbon dioxide from water-in a cylindrical test cell under different pressure conditions. Water was supersaturated with

  8. The equivalence myth of quantum mechanics-part II (United States)

    Muller, F. A.

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

A thorough numerical investigation is conducted distinguishing between trapped (ordered and chaotic) and escaping orbits. The determination of the location of the basins of escape towards the different escape channels and their correlations with the corresponding escape periods of the orbits is undoubtedly an issue of paramount importance. We consider four diffe...

  10. Slag Behavior in Gasifiers. Part II: Constitutive Modeling of Slag

    Directory of Open Access Journals (Sweden)

    Mehrdad Massoudi


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

  11. Parallel data access to regular nonorthogonal grid patterns. Part II (United States)

    Creutzburg, Reiner


    The aim of this paper that is organized in three parts is to introduce the concept of parallel access of data in regular but not orthogonal grids. Although the orthogonal grid and the corresponding sampling methods are well-known for many years and well established in science and technology, there is a certain interest in 2- and 3-dimensional imaging to study trigonal and hexagonal grids. In the 2-dimensional case these grids are generated by tesellation of the plane using triangles and hexagons, respectively. They form very regular patterns and they have very nice properties according to the number of neighborhood pixels and distance values in electronic imaging. Moreover, it is known for a long time that the retina part of the human visual system can be modeled by a hexagonal packing structure of rods and cones. In this paper we study the connection and the influence of the necessary data structures, access patterns, and system architecture to model imaging algorithms with trigonal and hexagonal grids. In particular, we study the parallel access to straight lines and hexagonal "circles". We show a possible parallel memory architecture for the parallel conflict-free access to rows, straight lines and hexagonal "circles". The necessary fundamental notions are given in this part.

  13. Hermeneutics as an approach to science: Part II (United States)

    Eger, Martin


    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.

  18. Prevention of Dealloying in Manganese Aluminium Bronze Propeller: Part II

    Directory of Open Access Journals (Sweden)

    Napachat Tareelap


    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.

    Fankhauser, Samuel, E-mail: [Grantham Research Institute and Centre for Climate Change Economics and Policy, London School of Economics, Houghton Street, London WC2A 2AE (United Kingdom); Hepburn, Cameron, E-mail: [Grantham Research Institute, London School of Economics, and Smith School for Enterprise and the Environment, Oxford University, 75 George Street, Oxford OX1 2BQ (United Kingdom)


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

  2. Nanoparticles and the blood coagulation system. Part II: safety concerns (United States)

    Ilinskaya, Anna N; Dobrovolskaia, Marina A


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

    Maojo, V; Garcia-Remesal, M; Bielza, C; Crespo, J; Perez-Rey, D; Kulikowski, C


    Biomedical Informatics (BMI) is a broad discipline, having evolved from both Medical Informatics (MI) and Bioinformatics (BI). An analysis of publications in the fieldshould provide an indication about the geographic distribution of BMI research contributions and possible lessons for the future, both for research and professional practice. In part I of our analysis of biomedical informatics publications we presented results from BMI conferences. In this second part, we analyse BMI journals, which provide a broader perspective and comparison between data from conferences and journals that ought to confirm or suggest alternatives to the original distributional findings from the conferences. We manually collected data about authors and their geographical origin from various MI journals: the International Journal of Medical Informatics (IJMI), the Journal of Biomedical Informatics (JBI), Methods of In formation in Medicine (MIM) and The Journal of the American Medical Informatics Association (JAMIA). Focusing on first authors, we also compared these findings with data from the journal Bioinformatics. Our results confirm those obtained in our analysis of BMI conferences - that local and regional authors favor their corresponding MI journals just as they do their conferences. Consideration of other factors, such as the increasingly open source nature of data and software tools, is consistent with these findings. Our analysis suggests various indicators that could lead to further, deeper analyses, and could provide additional insights for future BMI research and professional activities.

  4. Histologic features of alopecias: part II: scarring alopecias. (United States)

    Bernárdez, C; Molina-Ruiz, A M; Requena, L


    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.

  5. Autonomy, consent and responsibility. Part II. Informed consent in medical care and in the law. (United States)

    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.

  9. FSW Numerical Simulation of Aluminium Plates by SYSWELD - Part II

    Directory of Open Access Journals (Sweden)

    Jančo Roland


    Full Text Available Friction Stir Welding (FSW is one of the most effective solid state joining processes and has numerous potential applications in many industries. The simulation process can provide the evolution of physicals quantities such as temperature, metallurgical phase proportions, stress and strain which can be easily measured during welding. The numerical modelling requires the modelling of the complex interaction between thermal, metallurgical and mechanical phenomena. The aim of this paper is to describe the thermal-fluid simulation of FSW using the finite element method. In the theoretical part of paper heating is provided by the material flow and contact condition between the tool and the welded material. Thermal-mechanical results from the numerical simulation using SYSWELD are also presented for aluminium alloy.

  10. On the problem of ethnophyletism: a historical study. Part II

    Venediktov Vadim Yuriyevich


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

  11. Interacting quintessence from a variational approach Part II: derivative couplings

    CERN Document Server

    Boehmer, Christian G; Wright, Matthew


    We consider an original variational approach for building new models of quintessence interacting with dark or baryonic matter. The coupling is introduced at the Lagrangian level using a variational formulation for relativistic fluids, where the interacting term generally depends on both the dynamical degrees of freedom of the theory and their spacetime derivatives. After deriving the field equations from the action, we consider applications in the context of cosmology. Two simple models are studied using dynamical system techniques showing the interesting phenomenology arising in this framework. We find that these models contain dark energy dominated late time attractors with early time matter dominated epochs and also obtain a possible dynamical crossing of the phantom barrier. The formulation and results presented here complete and expand the analysis exposed in the first part of this work, where only algebraic couplings, without spacetime derivatives, were considered.

  12. Planar LTCC transformers for high voltage flyback converters: Part II.

    Schofield, Daryl (NASCENTechnology, Inc., Watertown, SD); Schare, Joshua M., Ph.D.; Slama, George (NASCENTechnology, Inc., Watertown, SD); Abel, David (NASCENTechnology, Inc., Watertown, SD)


    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.

  14. Eponyms in cardiothoracic radiology--part II: vascular. (United States)

    Mohammed, Tan-Lucien H; Saettele, Megan R; Saettele, Timothy; Patel, Vikas; Kanne, Jeffrey P


    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.

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

    CERN Document Server

    Moon, Woosok


    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...

  16. Practice improvement, part II: update on patient communication technologies. (United States)

    Roett, Michelle A; Coleman, Mary Thoesen


    Patient portals (ie, secure web-based services for patient health record access) and secure messaging to health care professionals are gaining popularity slowly. Advantages of web portals include timely communication and instruction, access to appointments and other services, and high patient satisfaction. Limitations include inappropriate use, security considerations, organizational costs, and exclusion of patients who are uncomfortable with or unable to use computers. Attention to the organization's strategic plan and office policies, patient and staff expectations, workflow and communication integration, training, marketing, and enrollment can facilitate optimal use of this technology. Other communication technologies that can enhance patient care include automated voice or text reminders and brief electronic communications. Social media provide another method of patient outreach, but privacy and access are concerns. Incorporating telehealthcare (health care provided via telephone or Internet), providing health coaching, and using interactive health communication applications can improve patient knowledge and clinical outcomes and provide social support.

  17. Recent applications of nuclear medicine in diagnostics: II part

    Directory of Open Access Journals (Sweden)

    Giorgio Treglia


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

  18. Advanced statistics: linear regression, part II: multiple linear regression. (United States)

    Marill, Keith A


    The applications of simple linear regression in medical research are limited, because in most situations, there are multiple relevant predictor variables. Univariate statistical techniques such as simple linear regression use a single predictor variable, and they often may be mathematically correct but clinically misleading. Multiple linear regression is a mathematical technique used to model the relationship between multiple independent predictor variables and a single dependent outcome variable. It is used in medical research to model observational data, as well as in diagnostic and therapeutic studies in which the outcome is dependent on more than one factor. Although the technique generally is limited to data that can be expressed with a linear function, it benefits from a well-developed mathematical framework that yields unique solutions and exact confidence intervals for regression coefficients. Building on Part I of this series, this article acquaints the reader with some of the important concepts in multiple regression analysis. These include multicollinearity, interaction effects, and an expansion of the discussion of inference testing, leverage, and variable transformations to multivariate models. Examples from the first article in this series are expanded on using a primarily graphic, rather than mathematical, approach. The importance of the relationships among the predictor variables and the dependence of the multivariate model coefficients on the choice of these variables are stressed. Finally, concepts in regression model building are discussed.

  19. Institutional Approach in Economics and to Economics. Part II

    Directory of Open Access Journals (Sweden)

    Yefimov Vladimir, M.


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

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

    KAUST Repository

    Rachidi, Mariam El


    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.

  1. Polymers Based on Renewable Raw Materials – Part II

    Directory of Open Access Journals (Sweden)

    Jovanović, S.


    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.

    Energy Technology Data Exchange (ETDEWEB)



    Medicine at the crossroads (a.k.a. The Future of Medicine) is an 8-part series of one-hour documentaries which examines the scientific and social forces that have shaped the practice of medicine around the world. The series was developed and produced over a five-year period and in eleven countries. Among the major issues examined in the series are the education of medical practitioners and the communication of medical issues. The series also considers the dilemmas of modern medicine, including the treatment of the elderly and the dying, the myth of the quick fix in the face of chronic and incurable diseases such as HIV, and the far-reaching implications of genetic treatments. Finally, the series examines the global progress made in medical research and application, as well as the questions remaining to be answered. These include not only scientific treatment, but accessibility and other critical topics affecting the overall success of medical advances. Medicine at the crossroads is a co-production of Thirteen/WNET and BBC-TV in association with Television Espafiola SA (RTVE) and the Australian Broadcasting Corporation. Stefan Moore of Thirteen/WNET and Martin Freeth of BBC-TV are series producers. George Page is executive in charge of medicine at the crossroads.

    Vinícius Pedrazzi


    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.

  5. Why does Bangladesh remain so poor? Part II: eight answers. (United States)

    Maloney, C


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

    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

  7. Stress analysis in oral obturator prostheses, part II: photoelastic imaging. (United States)

    Pesqueira, Aldiéris Alves; Goiato, Marcelo Coelho; da Silva, Emily Vivianne Freitas; Haddad, Marcela Filié; Moreno, Amália; Zahoui, Abbas; dos Santos, Daniela Micheline


    In part I of the study, two attachment systems [O-ring; bar-clip (BC)] were used, and the system with three individualized O-rings provided the lowest stress on the implants and the support tissues. Therefore, the aim of this study was to assess the stress distribution, through the photoelastic method, on implant-retained palatal obturator prostheses associated with different attachment systems: BOC--splinted implants with a bar connected to two centrally placed O-rings, and BOD--splinted implants with a BC connected to two distally placed O-rings (cantilever). One photoelastic model of the maxilla with oral-sinus-nasal communication with three parallel implants was fabricated. Afterward, two implant-retained palatal obturator prostheses with the two attachment systems described above were constructed. Each assembly was positioned in a circular polariscope and a 100-N axial load was applied in three different regions with implants by using a universal testing machine. The results were obtained through photograph record analysis of stress. The BOD system exhibited the highest stress concentration, followed by the BOC system. The O-ring, centrally placed on the bar, allows higher mobility of the prostheses and homogeneously distributes the stress to the region of the alveolar ridge and implants. It can be concluded that the use of implants with O-rings, isolated or connected with a bar, to rehabilitate maxillectomized patients allows higher prosthesis mobility and homogeneously distributes the stress to the alveolar ridge region, which may result in greater chewing stress distribution to implants and bone tissue. The clinical implication of the augmented bone support loss after maxillectomy is the increase of stress in the attachment systems and, consequently, a higher tendency for displacement of the prosthesis.

  9. Is extreme learning machine feasible? A theoretical assessment (part II). (United States)

    Lin, Shaobo; Liu, Xia; Fang, Jian; Xu, Zongben


    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.

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

    Directory of Open Access Journals (Sweden)

    Benedikt Buchspies


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


    Energy Technology Data Exchange (ETDEWEB)

    Hoffman, E.; Edwards, T.


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

Se augura que estos factores de riesgo de reciente descripción tendrán que ser tenidos muy en cuenta en un futuro no lejano, si se quiere predecir eficazmente la aparición de la preeclampsia para poder actuar así de forma precoz durante el desarrollo de la enfermedad, y evitar al máximo sus consecuencias obstétricas adversas, y en algunos casos, hasta para prevenir el surgimiento de esta enfermedad.This second part of the review deals with the new risk factors for preeclampsia, which are also known as emergent, among which the biological phenomena of endocrine and immunological type and related to endothelial dysfunction, such as the increase of oxidative stress, the reduction of antioxidant vitamins and others, are included. It is said that these recently described risk factors will have to be taken into account in a near future to efficiently predict the appearance of preeclampsia to act early during the development of the disease and to prevent as much as possible its adverse obstetric consequences and, in some cases, to avoid the appearance of this disease.

  4. New professions in librarianship

    Directory of Open Access Journals (Sweden)

    Violetta Bottazzo


    Full Text Available The article focuses on how information-communication and network computer technology effects changes in library operation and presents new possibilities in the development and differentiation of the librarian profession. At the time of the introduction of the Internet, numerous experts were convinced that the decline of librarianship, as a profession, was only a question of time. According to such opinions, users were supposed to search and obtain information on their own and purchase books through electronic bookstores. The reality turned out to be just the opposite. Nowadays, librarians are required to make more and more complex inquiries, to provide rapid, high-quality and non-stop services, to supply documents directly by computer or onto the working table. Moreover, librarians must follow the rapid development of the profession and participate in permanent and polyvalent training. The introduction of the digitalisation of materials and the future development of libraries require that librarians familiarize themselves with complex hypertext protocols, graphic design, and marketing. Moreover, librarians are obliged to accept any change brought about during the process of technological development. Therefore, in the developed world, new professions are being established and relating to the provision of aggregate information in form of various services and products. Those professions do not only imply universal information providers but trained experts with regard to individual fields of interest.

    Being able to predict which residents will likely be unsuccessful on high-stakes exams would allow residency programs to provide early intervention. To determine whether measures of clinical performance in clerkship (in-training evaluation reports) and first year of residency (program director ratings) predict pass-fail performance on the Medical Council of Canada Qualifying Exam Part II (MCCQE Part II). Residency program directors assessed the performance of our medical school graduates (Classes 2004-2007) at the end of the 1st postgraduate year. We subsequently collected clerkship in-training evaluation reports for these graduates. Using a neutral third party and unique codes, an anonymous dataset containing clerkship, residency, and MCCQE Part II performance scores was created for our use. Data were analyzed using descriptive statistics, correlations, receiver operating characteristics, and the Youdin index. Regression was also performed to further study the relationship among the variables. Complete data were available for 78.6% of the graduates. Of these participants, 94% passed the licensing exam on their first attempt. Receiver operating characteristics revealed that the area under the curve for clerkship in-training evaluation reports was 0.67 (ptraining evaluation reports and residency program director assessments were 0.30 and 0.23, respectively. Although clerkship in-training evaluation reports and residency program director ratings are significant predictors of pass-fail performance on the MCCQE Part II, the effectiveness of each one to predict pass-fail performance was relatively small. Reasons for these findings are discussed.

    Full Text Available New technologies can foster the impression that journalism, as a profession will become extinct probably in a short term. Anybody can have access to any information sources as well as to transmit – through Internet- all sorts of messages at an unusual speed, and this fact seems to support the idea that no technical training will be needed in the future not even an specific cultural background will be required, much less an university degree or qualification that ensures a responsible and appropriate practice of the modern social communication. The Federation of Journalists Associations in Spain (FAPE in its Draft of the Professional Statute is in favor of a graduated or qualified profession at an university level, and its Commission for Complaints has been developing a successful work regarding the professional self-regulation and self-control for the benefit of society. Therefore, there are good reasons for being optimist. Journalism, as a profession, is not going to disappear, and maybe it is time to consider it, really, as an academic qualified profession.

  16. Teaching as a Profession (United States)

    Robards, Shirley N.


    The image of the schools and the teaching profession according to the media is usually negative.

  18. In vitro performance of Class I and II composite restorations: a literature review on nondestructive laboratory trials--part II. (United States)

    Dietschi, D; Argente, A; Krejci, I; Mandikos, M


    A literature review was conducted on adhesive Class I and II restorations and nondestructive in vitro tests using the PubMed/Medline database for the 1995-2010 period. The first part of this review has presented and critically appraised selected literature dealing with the quality and in vitro behavior of adhesive Class II restorations using photoelasticity, finite element analysis, and microleakage study protocols. This second part reviews additional parameters, which are deformation and fracture resistance to cyclic loading, shrinkage stress and tooth deformation following restoration placement, bond strength (microtensile, tensile, and shear tests), and marginal and internal adaptation. In addition, a "relevance score" has been proposed that aims to classify the different study protocols according, firstly, to the resulting quality, quantity, and consistency of the evidence and then, secondly, to their potential clinical relevance, as estimated by their ability to simulate oral and biomechanical strains. The highest clinical relevance was attributed to marginal and internal adaptation studies, following cyclic loading in a moist environement. However, a combination of in vitro protocols will have an even greater predictive potential and has to be considered as a crucial preclinical research approach with which to investigate the numerous restorative configurations that cannot be efficiently and rapidly tested in vivo.

  19. Student nurse satisfaction levels with their courses: Part II--effects of academic variables. (United States)

    El Ansari, Walid


    The degree of student satisfaction with their educational experiences is an important dimension in the assessment of institutional effectiveness. All nursing education teams are currently working on ways to improve the quality of their educational provision and increase the satisfaction of their students. This is the second of a two-part article on the factors that influence student satisfaction with their courses. Part I examined how the four demographic features of gender, disability, ethnicity and age influenced student satisfaction and their performance on nursing modules. This paper complements Part I by examining the effects of three educational factors (academic level of the module, mode of study, and the qualification aim) on the accomplishment and satisfaction levels of 460 students attending multidisciplinary health care modules at the School of Health Care, Oxford Brookes University, 2000/2001. The study found that in contrast to Level 1 students, Level 3 participants felt the need for modules to stimulate more interest, that module teams be more skilled and knowledgeable and that library resources be more abundant. The findings also suggested that part-time students required significantly more attention than full-time participants in terms of the need for smaller seminar groups that would facilitate contributions and decrease inhibitions among students, and were more concerned with the utility and relevance of their learning in relation to their chosen professions. Diploma participants had the highest satisfaction followed by the BA and then the BSc students. The findings raise issues which are of interest to academic staff and nursing students, and the implications for nurse education and curriculum design are discussed within the context of student nurse satisfaction and quality issues of learning and teaching in higher education.

  1. Developing the profession of radiography: Making use of oral history

    Energy Technology Data Exchange (ETDEWEB)

    Decker, Sola [School of Radiography, Faculty of Nursing, Midwifery and Health Studies, University of Wales, Bangor, Archimedes Centre, Technology Park, Wrexham LL13 7YP (United Kingdom)]. E-mail:; Iphofen, Ron [Faculty of Nursing, Midwifery and Health Studies, University of Wales, Bangor, Archimedes Centre, Technology Park, Wrexham LL13 7YP (United Kingdom)


    This paper is based on ongoing research into the profession of radiography using the oral history method. Knowledge of radiographic practice as a profession has in the past been based on what is written or learnt from other professions both within and beyond the field of health care. The profession has experienced substantial technological and sociological changes both in training and in practice over the past few decades and these look set to continue into the immediate future. Evidence-based practice is invoked as a quality measure on all health professions, and part of the body of knowledge which forms the evidence base of practice development involves an understanding of how the profession has responded to change and what this might mean for the further changes it is likely to meet. This paper explores the potential role of oral history research as a tool for the development of knowledge about the practice of radiography.

  2. Growth theory after Keynes, part II: 75 years of obstruction by the mainstream economics culture

    Directory of Open Access Journals (Sweden)

    Hendrik Van den Berg


    Full Text Available Part I of this essay explained the sequence of events that enabled the neoclassical paradigm to regain its dominant position in mainstream economics following serious challenges by ‘Keynesian’ economists. This second essay seeks to answer the question of why the economics profession was so willing to sustain the neoclassical paradigm in the face of the reality-based challenges by ‘Keynesian’ economists like Harrod and Domar. The answer is sought in the culture of economics, the history of science in general, and the study of power in the field of political economy. This article draws heavily on the work of the French sociologist Pierre Bourdieu, who divides culture into habitus (procedures and dispositions and doxa (more abstract beliefs and philosophies, in order to provide insight into how culture affects economic thinking. Bourdieu’s concept of symbolic violence helps to explain how a narrower neoclassical growth model was enthusiastically accepted as a replacement for the ‘Keynesian’ Harrod-Domar growth model. Financial and business interests clearly understood the power of culture and they used their accumulated wealth to support the neoliberal doxa and neoclassical habitus that would induce economists to willingly provide intellectual cover for policies that benefitted those financial and business interests. We conclude with a discussion on how the history of thought on economic development might have evolved if the Keynesian paradigm, and its dynamic Harrod-Domar model, had prevailed

  5. Clinical librarianship in the UK: temporary trend or permanent profession? Part I: a review of the role of the clinical librarian. (United States)

    Sargeant, Sally J E; Harrison, Janet


    This paper is the first of a two-part series of articles presenting the role of the clinical librarian (CL) in the UK today. It situates the CL concept historically, and specifically reports the findings from a study in 2002 (Skinner, The Role of the Clinical Librarian in the UK. MSc Dissertation. Loughborough University: Department of Information Science). The impetus for the 2002 study was the awareness of an increase in job advertisements within the NHS for roles seeking to enhance the practice of evidence-based medicine, which included elements of clinical librarianship. Therefore the research was undertaken to establish whether this increase was coincidental, or the beginning of a new professional role for librarians. A content analysis of CL job advertisements, examining job titles and duties was undertaken. Twenty-three advertisements were scrutinized, and these results are presented here. As a complementary investigation, a postal questionnaire was sent to a sample of practising CLs in the UK. Several duties can be classified as core to the role of the CL. However there is a great diversity of duties attached to this core, reflecting an absence of nationally accepted practice. Further work was necessary to assess current practice and how clinical librarianship can continue to grow at local and national levels. This is addressed in Part Two of this series.

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

    Directory of Open Access Journals (Sweden)

    Zsolt Gáspár


    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.

  15. Alchemical poetry in medieval and early modern Europe: a preliminary survey and synthesis. Part II - Synthesis. (United States)

    Kahn, Didier


    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.

  16. Profession and professionalisation in medical radiation science as an emergent profession

    Energy Technology Data Exchange (ETDEWEB)

    Sim, Jenny [RMIT University, Medical Radiations, School of Medical Sciences, PO Box 71, Bundoora, Victoria 3083 (Australia)], E-mail:; Radloff, Alex [Central Queensland University, Rockhampton Campus, Bruce Highway, North Rockhampton, Queensland 4702 (Australia)], E-mail:


    Purpose: Deregulation, reduced operating costs, new ways of organising the professional workforce, increasing competition within the healthcare sector and increasing consumer expectations are factors that challenge any health profession. This paper, which forms part of the first author's doctoral study on continuing professional development in medical radiation science, details the journey of medical radiation science as a profession in Australia. Specifically, the paper examines the challenges confronting practitioners in their struggle to be recognised as a profession in its own right. Findings: The challenges facing medical radiation science practitioners included low professional self-esteem and apathy, which adversely affects their willingness and ability to continue learning and to assume increasing work responsibilities which are essential attributes of a health professional. Low self-esteem and apathy are also preventing practitioners from venturing beyond their comfort zone of daily workplace practices. This ultimately impacts on their ability to advance clinical practice in response to a constantly changing health care system. Conclusion: Despite the current difficulties confronting the profession, it is possible for practitioners to assume a more proactive role in moving the profession forward. As part of the solution to improving practitioners' low self-esteem and to rekindling their enthusiasm for the profession, the authors propose that continuing professional development programs should go beyond simply assisting practitioners in advancing clinical competence. They should also aim to empower practitioners to develop their reflective skills. Reflection is now widely promoted in healthcare professions as one of the means of enhancing clinical practice and improving healthcare delivery. To this end, educational designers should incorporate reflection into professional development programs as both a learning goal and a strategy. Helping

  20. A legacy of struggle: the OSHA ergonomics standard and beyond, Part II. (United States)

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


    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.

  1. A Lagrangian variational formulation for nonequilibrium thermodynamics. Part II: Continuum systems (United States)

    Gay-Balmaz, François; Yoshimura, Hiroaki


    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.

  3. Photometry of Type II Cepheid Candidates from the Northern Part of the All Sky Automated Survey (United States)

    Schmidt, Edward G.; Hemen, Brian; Rogalla, Danielle; Thacker-Lynn, Lauren


    We have obtained VR photometry of 282 Cepheid variable star candidates from the northern part of the All Sky Automated Survey (ASAS). These together with data from the ASAS and the Northern Sky Variability Survey (NSVS) were used to redetermine the periods of the stars. We divided the stars into four groups based on location in a plot of mean color, langV-Rrang, versus period. Two of the groups fell within the region of the diagram containing known type II Cepheids and yielded 14 new highly probable type II Cepheids. The properties of the remaining stars in these two groups are discussed but their nature remains uncertain. Unexplained differences exist between the sample of stars studied here and a previous sample drawn from the NSVS by Akerlof et al. This suggests serious biases in the identification of variables in different surveys.

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

    Energy Technology Data Exchange (ETDEWEB)

    Romanov, Gennady


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

  5. 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.


    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.

    Eremeev Anton V.


    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.

  8. A framework for biodynamic feedthrough analysis--part II: validation and application. (United States)

    Venrooij, Joost; van Paassen, Marinus M; Mulder, Mark; Abbink, David A; Mulder, Max; van der Helm, Frans C T; Bulthoff, Heinrich H


    Biodynamic feedthrough (BDFT) is a complex phenomenon, that has been studied for several decades. However, there is little consensus on how to approach the BDFT problem in terms of definitions, nomenclature, and mathematical descriptions. In this paper, the framework for BDFT analysis, as presented in Part I of this dual publication, is validated and applied. The goal of this framework is twofold. First of all, it provides some common ground between the seemingly large range of different approaches existing in BDFT literature. Secondly, the framework itself allows for gaining new insights into BDFT phenomena. Using recently obtained measurement data, parts of the framework that were not already addressed elsewhere, are validated. As an example of a practical application of the framework, it will be demonstrated how the effects of control device dynamics on BDFT can be understood and accurately predicted. Other ways of employing the framework are illustrated by interpreting the results of three selected studies from the literature using the BDFT framework. The presentation of the BDFT framework is divided into two parts. This paper, Part II, addresses the validation and application of the framework. Part I, which is also published in this journal issue, addresses the theoretical foundations of the framework. The work is presented in two separate papers to allow for a detailed discussion of both the framework's theoretical background and its validation.

    Spine biomechanics provide the foundation for the disciplines of spine medicine and spine surgery. Although modern spine biomechanics emerged during the second half of the last century, it has many ancient, medieval, and post-Renaissance roots. In Part I of this series, the ancient and medieval roots of spine biomechanics were reviewed. In Part II, the effects of post-Renaissance scientists on the development of modern spine biomechanics, as well as the studies on gait, bone, and muscles performed before the 20th century, are reviewed. Subsequently, war-related studies performed in the 20th century contributed to the formation of modern biomechanics. The first biomechanics-related organizations and scientific publications did not emerge until the second half of the 20th century. These events provided the final bricks in the foundation that facilitated the emergence of modern spine biomechanics research.

  11. Practical application of new technologies for melanoma diagnosis: Part II. Molecular approaches. (United States)

    March, Jordon; Hand, Matthew; Truong, Amanda; Grossman, Douglas


    The criterion standard for diagnosing cutaneous melanoma continues to be histologic examination. However, classifying some melanocytic lesions by conventional microscopy can be problematic if they exhibit some architectural or morphologic characteristics of both nevus and melanoma. Moreover, histologic appearance does not always predict biologic behavior. There is therefore a need and opportunity to develop new technologies that can facilitate the histologic diagnosis of melanoma and potentially help distinguish lesions with a lesser or greater risk of metastasis. In part II of this 2-part continuing medical education article, we will review the molecular technologies currently available for facilitating melanoma diagnosis, including comparative genomic hybridization, fluorescence in situ hybridization, and epidermal genetic retrieval. Our goal is to provide the clinician with an up to date understanding of these molecular approaches so that they can be applied to their management of challenging melanocytic lesions.

  12. Exploring Cancer Therapeutics with Natural Products from African Medicinal Plants, Part II: Alkaloids, Terpenoids and Flavonoids. (United States)

    Nwodo, Justina N; Ibezim, Akachukwu; Simoben, Conrad V; Ntie-Kang, Fidele


    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.

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

    Directory of Open Access Journals (Sweden)

    M. T. Schobeiri


    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.

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

  17. Mineral resources of parts of the Departments of Antioquia and Caldas, Zone II, Colombia (United States)

    Hall, R.B.; Feininger, Tomas; Barrero, L.; Dario, Rico H.; ,; Alvarez, A.


    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

  18. Analysis of Radionuclide Releases from the Fukushima Dai-ichi Nuclear Power Plant Accident Part II (United States)

    Achim, Pascal; Monfort, Marguerite; Le Petit, Gilbert; Gross, Philippe; Douysset, Guilhem; Taffary, Thomas; Blanchard, Xavier; Moulin, Christophe


    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.

  19. Two-loop renormalization in the standard model, part II. Renormalization procedures and computational techniques

    Energy Technology Data Exchange (ETDEWEB)

    Actis, S. [Deutsches Elektronen-Synchrotron (DESY), Zeuthen (Germany); Passarino, G. [Torino Univ. (Italy). Dipt. di Fisica Teorica; INFN, Sezione di Torino (Italy)


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

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

    Energy Technology Data Exchange (ETDEWEB)


    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.

  2. The Evolution of the Dental Assisting Profession. (United States)

    Kracher, Connie; Breen, Carolyn; McMahon, Kim; Gagliardi, Lorraine; Miyasaki, Cara; Landsberg, Katherine; Reed, Constance


    The objectives of this article are to describe the dental assistant's role in the dental delivery system; assess the educational structure of the dental assisting profession; and project factors likely to impact the future role of the dental assistant. The article summarizes the current status and trends of the dental assisting profession including general responsibilities, credentialing, and regulation. An overview of the workforce and parameters of employment is provided with a description of the broad scope of practice, education, and licensure options, which vary by state. Existing academic models and enrollment trends in accredited dental programs are included, as are the strengths and weaknesses of the current educational system. Multiple factors may impact the future of this profession. To address the anticipated increase in the demand for and responsibilities of dental assistants, curricular revisions will be needed to prepare for implementation of interprofessional care models in which dental assistants will play a vital role. Well-educated dental assistants will be needed to support viable models of dental care and wellness in the U.S. Enhanced career opportunities and varied employment environments may increase job satisfaction and practice longevity. As protection of the public is of the utmost importance in the dental profession, this evolving dental clinician must be formally educated in all aspects of clinical practice and be permitted to perform delegated patient care, as legally allowed by their states. This article was written as part of the project "Advancing Dental Education in the 21st Century."

  6. Compassionate care: enhancing physician-patient communication and education in dermatology: Part II: Patient education. (United States)

    Hong, Judith; Nguyen, Tien V; Prose, Neil S


    Patient education is a fundamental part of caring for patients. A practice gap exists, where patients want more information, while health care providers are limited by time constraints or difficulty helping patients understand or remember. To provide patient-centered care, it is important to assess the needs and goals, health beliefs, and health literacy of each patient. This allows health care providers to individualize education for patients. The use of techniques, such as gaining attention, providing clear and memorable explanations, and assessing understanding through "teach-back," can improve patient education. Verbal education during the office visit is considered the criterion standard. However, handouts, visual aids, audiovisual media, and Internet websites are examples of teaching aids that can be used as an adjunct to verbal instruction. Part II of this 2-part series on patient-physician interaction reviews the importance and need for patient education along with specific guidelines and techniques that can be used.

  7. The spectrum of oculocutaneous disease: Part II. Neoplastic and drug-related causes of oculocutaneous disease. (United States)

    Day, Antoinette; Abramson, Amanda K; Patel, Mahir; Warren, Richard B; Menter, M Alan


    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.

  8. From Constraints to Resolution Rules Part II : chains, braids, confluence and T&E (United States)

    Berthier, Denis

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

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

    LENUS (Irish Health Repository)

    Killeen, Ronan P


    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.

  10. Music in the exercise domain: a review and synthesis (Part II) (United States)

    Karageorghis, Costas I.; Priest, David-Lee


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

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

    CERN Document Server

    Huang, Xuan-Chao


    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...

  12. Mechanical performance of carbon-epoxy laminates. Part II: quasi-static and fatigue tensile properties

    Directory of Open Access Journals (Sweden)

    José Ricardo Tarpani


    Full Text Available In Part II of this work, quasi-static tensile properties of four aeronautical grade carbon-epoxy composite laminates, in both the as-received and pre-fatigued states, have been determined and compared. Quasi-static mechanical properties assessed were tensile strength and stiffness, tenacity (toughness at the maximum load and for a 50% load drop-off. In general, as-molded unidirectional cross-ply carbon fiber (tape reinforcements impregnated with either standard or rubber-toughened epoxy resin exhibited the maximum performance. The materials also displayed a significant tenacification (toughening after exposed to cyclic loading, resulting from the increased stress (the so-called wear-in phenomenon and/or strain at the maximum load capacity of the specimens. With no exceptions, two-dimensional woven textile (fabric pre-forms fractured catastrophically under identical cyclic loading conditions imposed to the fiber tape architecture, thus preventing their residual properties from being determined.

  13. Putting microbes to work: dairy fermentation, cell factories and bioactive peptides. Part II: bioactive peptide functions. (United States)

    Hayes, Maria; Stanton, Catherine; Fitzgerald, Gerald F; Ross, R Paul


    A variety of milk-derived biologically active peptides have been shown to exert both functional and physiological roles in vitro and in vivo, and because of this are of particular interest for food science and nutrition applications. Biological activities associated with such peptides include immunomodulatory, antibacterial, anti-hypertensive and opioid-like properties. Milk proteins are recognized as a primary source of bioactive peptides, which can be encrypted within the amino acid sequence of dairy proteins, requiring proteolysis for release and activation. Fermentation of milk proteins using the proteolytic systems of lactic acid bacteria is an attractive approach for generation of functional foods enriched in bioactive peptides given the low cost and positive nutritional image associated with fermented milk drinks and yoghurt. In Part II of this review, we focus on examples of milk-derived bioactive peptides and their associated health benefits, to illustrate the potential of this area for the design and improvement of future functional foods.

  15. Repository Planning, Design, and Engineering: Part II-Equipment and Costing. (United States)

    Baird, Phillip M; Gunter, Elaine W


    Part II of this article discusses and provides guidance on the equipment and systems necessary to operate a repository. The various types of storage equipment and monitoring and support systems are presented in detail. While the material focuses on the large repository, the requirements for a small-scale startup are also presented. Cost estimates and a cost model for establishing a repository are presented. The cost model presents an expected range of acquisition costs for the large capital items in developing a repository. A range of 5,000-7,000 ft(2) constructed has been assumed, with 50 frozen storage units, to reflect a successful operation with growth potential. No design or engineering costs, permit or regulatory costs, or smaller items such as the computers, software, furniture, phones, and barcode readers required for operations have been included.

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

    Directory of Open Access Journals (Sweden)

    Yuan Yang


    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.

  20. Reciprocity-enhanced optical communication through atmospheric turbulence - part II: communication architectures and performance (United States)

    Puryear, Andrew L.; Shapiro, Jeffrey H.; Parenti, Ronald R.


    Free-space optical communication provides rapidly deployable, dynamic communication links that are capable of very high data rates compared with those of radio-frequency systems. As such, free-space optical communication is ideal for mobile platforms, for platforms that require the additional security afforded by the narrow divergence of a laser beam, and for systems that must be deployed in a relatively short time frame. In clear-weather conditions the data rate and utility of free-space optical communication links are primarily limited by fading caused by micro-scale atmospheric temperature variations that create parts-per-million refractive-index fluctuations known as atmospheric turbulence. Typical communication techniques to overcome turbulence-induced fading, such as interleavers with sophisticated codes, lose viability as the data rate is driven higher or the delay requirement is driven lower. This paper, along with its companion [J. H. Shapiro and A. Puryear, "Reciprocity-Enhanced Optical Communication through Atmospheric Turbulence-Part I: Reciprocity Proofs and Far-Field Power Transfer"], present communication systems and techniques that exploit atmospheric reciprocity to overcome turbulence which are viable for high data rate and low delay requirement systems. Part I proves that reciprocity is exhibited under rather general conditions, and derives the optimal power-transfer phase compensation for far-field operation. The Part II paper presents capacity-achieving architectures that exploit reciprocity to overcome the complexity and delay issues that limit state-of-the art free-space optical communications. Further, this paper uses theoretical turbulence models to determine the performance—delay, throughput, and complexity—of the proposed architectures.

  1. The history of the nurse anesthesia profession. (United States)

    Ray, William T; Desai, Sukumar P


    Despite the fact that anesthesia was discovered in the United States, we believe that both physicians and nurses are largely unaware of many aspects of the development of the nurse anesthetist profession. A shortage of suitable anesthetists and the reluctance of physicians to provide anesthetics in the second half of the 19th century encouraged nurses to take on this role. We trace the origins of the nurse anesthetist profession and provide biographical information about its pioneers, including Catherine Lawrence, Sister Mary Bernard Sheridan, Alice Magaw, Agatha Cobourg Hodgins, and Helen Lamb. We comment on the role of the nuns and the effect of the support and encouragement of senior surgeons on the development of the specialty. We note the major effect of World Wars I and II on the training and recruitment of nurse anesthetists. We provide information on difficulties faced by nurse anesthetists and how these were overcome. Next, we examine how members of the profession organized, developed training programs, and formalized credentialing and licensing procedures. We conclude by examining the current state of nurse anesthesia practice in the United States. Copyright © 2016 Elsevier Inc. All rights reserved.

  3. Quality engineering as a profession.

    Energy Technology Data Exchange (ETDEWEB)

    Kolb, Rachel R.; Hoover, Marcey L.


    Over the course of time, the profession of quality engineering has witnessed significant change, from its original emphasis on quality control and inspection to a more contemporary focus on upholding quality processes throughout the organization and its product realization activities. This paper describes the profession of quality engineering, exploring how todays quality engineers and quality professionals are certified individuals committed to upholding quality processes and principles while working with different dimensions of product development. It also discusses the future of the quality engineering profession and the future of the quality movement as a whole.

  4. Professing faith, professing medicine: Physicians and the call to evangelize. (United States)

    Bochanski, Philip G


    THE HIPPOCRATIC OATH TRADITIONALLY ESTABLISHES MEDICINE AS A PROFESSION: A career, or vocation based on the professing of an oath regarding personal and public behavior. For Catholic physicians, the commitments of the Oath of Hippocrates take on new meaning when seen in light of the promises made at Baptism and renewed every Easter. This paper, originally an address to medical students, considers the role of Catholic physicians as evangelizers, those who spread the message and values of the Gospel of Jesus Christ.

  5. [Education in our time: competency or aptitude? The case for medicine. Part II]. (United States)

    Viniegra-Velázquez, Leonardo

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

  6. Interview-Based Qualitative Research in Emergency Care Part II: Data Collection, Analysis and Results Reporting (United States)

    Ranney, Megan L.; Meisel, Zachary; Choo, Esther K.; Garro, Aris; Sasson, Comilla; Morrow, Kathleen


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

  7. Fall prevention in frail elderly nursing home residents: a challenge to case management: part II. (United States)

    Theodos, Phyllis


    Parts I and II of this article examine the impact of a falls prevention program on the fall incidents among the residents in a nursing home. It was hypothesized that a diagnostic, therapeutic, and preventive approach should be used for nursing home residents identified as being at high risk for falls in order to reduce the number of fall incidents and to improve quality of life for this vulnerable population. The program effectively targeted both intrinsic and extrinsic factors to reduce risks facing the residents. The effectiveness of the program was evaluated by examining changes in the rate of falls after the program was implemented. The results identified that a multifaceted program, one that utilized multiple personalized interventions, was effective in reducing the falls rate of frail (those with complex medical and psychosocial problems) nursing home residents, and that muscle-strengthening interventions may be beneficial for this vulnerable population. Program outcomes verified that case managers can impact quality of life for frail elderly nursing home residents by promoting their independence and safety, and postponing problems resulting from inactivity. Part I (LCM, Nov-Dec 2001) discussed the background and process of a falls program and factors contributing to the occurrence of falls. This month we examine the interdisciplinary team approach to assessment, method, and implementing strategies for an effective fall prevention program. Tools used for prevention, monitoring, and investigation of falls are also detailed.

  8. Long-term solar activity and terrestrial connections. Part II: at the beckon of the sun?

    Directory of Open Access Journals (Sweden)

    N. D. Diamantides


    Full Text Available The research task described herein aims at the structuring of an analytical tool that traces the time course of geophysical phenomena, regional or global, and compares it to the course of long-term solar conditions, long-term meaning decades or a few centuries. The model is based on the premise that since in a last analysis the preponderance of atmospheric, hydrospheric, and, possibly, some aspects of geospheric phenomena are, or have been, powered by energy issuing from the sun - either now or in the past - the long-term behavior of such phenomena is ultimately "connected" to long-term changes occurring in the sun itself. Accordingly, the proposed research firstly derives and models a stable surrogate pattern for the long-term solar activity, secondly introduces a transfer-function algorithm for modeling the connection between the surrogate and terrestrial phenomena viewed as partners in the connection, and thirdly probes the connection outcome for episodic or unanticipated effects that may arise due to the fact that in the present context, the connection, should it exist, is very likely nonlinear. Part I of the study presents the theory of the concept, while Part II demonstrates the concept's pertinence to a number of terrestrial phenomena.Key words. Solar activity · Kolmogorov algorithm

  9. Pharmacokinetics, Pharmacodynamics, and Pharmacogenomics of Immunosuppressants in Allogeneic Hematopoietic Cell Transplantation: Part II. (United States)

    McCune, Jeannine S; Bemer, Meagan J; Long-Boyle, Janel


    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.

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

    Wakefield, J C


    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.

  12. A novel embeddable spherical smart aggregate for structural health monitoring: part II. Numerical and experimental verifications (United States)

    Kong, Qingzhao; Fan, Shuli; Mo, Y. L.; Song, Gangbing


    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.

  13. Health professions students' use of social media. (United States)

    Giordano, Carolyn; Giordano, Christine


    The internet is increasingly a part of everyday life by facilitating networking opportunities and offering ways to associate with others who have similar interests, values, or goals. An online survey was administered to 644 first-year students and 413 graduating students via Surveymonkey to investigate their media preferences, to gauge if they are active on social media sites, and to evaluate how they responded to advertisements. Students were in the following health professions: biotechnology, couple and family therapy, medicine, nursing, occupational therapy, physical therapy, public health, radiologic and imaging sciences, and pharmacy. Results indicate that students prefer online media as their primary source of information. The majority of students were using Facebook, and very few were using Twitter or LinkedIn or other social networking sites. Understanding social media usage has several implications for educating, connecting with, and researching health professions students from all stages of their academic career.

  14. Rare or remarkable microfungi from Oaxaca (south Mexico)--Part II. (United States)

    Ale-Agha, N; Jensen, M; Brassmann, M; Kautz, S; Eilmus, S; Ballhorn, D J


    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.

  15. Gunshot residue testing in suicides: Part II: Analysis by inductive coupled plasma-atomic emission spectrometry. (United States)

    Molina, D Kimberley; Castorena, Joe L; Martinez, Michael; Garcia, James; DiMaio, Vincent J M


    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.

  16. On the Processing of Spalling Experiments. Part II: Identification of Concrete Fracture Energy in Dynamic Tension (United States)

    Lukić, Bratislav B.; Saletti, Dominique; Forquin, Pascal


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

Os resultados mostram que 15% de CCAN é factível de ser empregado em concreto porque apresenta desempenho superior ao concreto referência, quando usado cimento com pozolanas e próximos ou até superiores às misturas de CCAM, para grande parte das variáveis estudadas. Conclui-se que 15% de CCAN para concreto estrutural é viável e traz maior sustentabilidade.

  18. Sludge in the pulp and paper industry in Sweden, part II[Combustion of]; Slam fraan skogsindustrin, fas II

    Gyllenhammar, Marianne; Herstad Svaerd, Solvie; Kjoerk, Anders; Larsson, Sara; Wennberg, Olle [S.E.P. Scandinavian Energy Project AB, Goeteborg (Sweden); Aamand, Lars-Erik [Chalmers Univ. of Technology, Goeteborg (Sweden); Eskilsson, David [Swedish National Testing and Research Inst., Boraas (Sweden)


    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

  19. Children's exposure to indoor air in urban nurseries--Part II: Gaseous pollutants' assessment. (United States)

    Branco, P T B S; Nunes, R A O; Alvim-Ferraz, M C M; Martins, F G; Sousa, S I V


    This study, Part II of the larger study "Children's exposure to indoor air in urban nurseries", aimed to: (i) evaluate nursery schools' indoor concentrations of several air pollutants in class and lunch rooms; and (ii) analyse them according to guidelines and references. Indoor continuous measurements were performed, and outdoor concentrations were obtained to determine indoor/outdoor ratios. The influence of outdoor air seemed to be determinant on carbon monoxide (CO), nitrogen dioxide (NO2) and ozone (O3) indoor concentrations. The peak concentrations of formaldehyde and volatile organic compounds (VOC) registered (highest concentrations of 204 and 2320 µg m(-3) respectively), indicated the presence of specific indoor sources of these pollutants, namely materials emitting formaldehyde and products emitting VOC associated to cleaning and children's specific activities (like paints and glues). For formaldehyde, baseline constant concentrations along the day were also found in some of the studied rooms, which enhances the importance of detailing the study of children's short and long-term exposure to this indoor air pollutant. While CO, NO2 and O3 never exceeded the national and international reference values for IAQ and health protection, exceedances were found for formaldehyde and VOC. For this reason, a health risk assessment approach could be interesting for future research to assess children's health risks of exposure to formaldehyde and to VOC concentrations in nursery schools. Changing cleaning schedules and materials emitting formaldehyde, and more efficient ventilation while using products emitting VOC, with the correct amount and distribution of fresh air, would decrease children's exposure.

  2. Niacin Alternatives for Dyslipidemia: Fool's Gold or Gold Mine? Part II: Novel Niacin Mimetics. (United States)

    Goel, Harsh; Dunbar, Richard L


    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.

  3. Effects of hypobaric pressure on human skin: implications for cryogen spray cooling (part II). (United States)

    Aguilar, Guillermo; Franco, Walfre; Liu, Jie; Svaasand, Lars O; Nelson, J Stuart


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

  4. Reciprocating gait orthosis powered with electrical muscle stimulation (RGO II). Part II: Medical evaluation of 70 paraplegic patients. (United States)

    Solomonow, M; Reisin, E; Aguilar, E; Baratta, R V; Best, R; D'Ambrosia, R


    Medical evaluation was performed on a group of paraplegics who were trained to walk with the Reciprocating Gait Orthosis powered with electrical muscle stimulation (RGO II). The evaluation included changes in spasticity, cholesterol level, bone metabolism, cardiac output and stroke volume, vital capacity, knee extensors torque, and heart rate at the end of a 30-meter walk. After an average of 14 weeks of training during which patients walked for 3 hours per week, significant reductions in spasticity, total cholesterol and low-density lipids, hydroxyproline/creatinine ratio, and increased knee extensor torque were evident. The data also showed that improvements occurred in the calcium/creatinine ratio, serum calcium and alkaline phosphatase levels, cardiac output and stroke volume, and vital capacity, yet these improvements were not statistically significant. The final heart rate at the end of a 30-meter walk showed that the RGO II required only a moderate level of exertion, which was found to be the lowest among the other mechanical or muscle stimulation orthoses available to paraplegics. It was concluded that the limited but reasonable level of functional regain provided by the RGO II is associated with a general improvement in the paraplegic's physiological condition if used for a minimum of 3 to 4 hours per week.

  5. Testing and Analysis of a Composite Non-Cylindrical Aircraft Fuselage Structure . Part II; Severe Damage (United States)

    Przekop, Adam; Jegley, Dawn C.; Lovejoy, Andrew E.; Rouse, Marshall; Wu, Hsi-Yung T.


    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.

In Part II of this tutorial, we focus on diagnostics of mixing and the problem of enhancing mixing by boundary feedback control. Diagnostic tools from dynamical systems theory are presented that enable detection and quantification of chaotic transport in periodically perturbed systems. However, real systems are generally not periodic, and available measurements or simulations are finite in time. A method for quantifying mixing in finite-time velocity fields is discussed, and applied to data obtained from simulations of the 2D controlled channel flow. Mixing has traditionally been brought on by open-loop control strategies, such as stirring, jet injection or mixing valves. Applications of active feedback to mixing problems are scarce in the literature, but the idea is currently drawing attention from various research groups. Feedback laws for the purpose of mixing enhancement in 2D and 3D pipe flow are presented, and simulations show that they induce strong mixing.

  7. Familial breast cancer. Part II: Relationships with histology, staging, steroid receptors and serum tumor markers. (United States)

    Gavrilov, I; Nacheva, M; Tzingilev, D


    To identify differences in clinical characteristics, histological features, hormone receptor status, and tumor marker expression between patients with sporadic and familial breast cancer. As in the previous Part I of this study, two groups of women with breast cancer were compared. The first group (group I) included 504 patients with a family history of breast cancer. The second (control) group (group II) consisted of 300 patients not reporting such a history in their relatives. The examined parameters in this report were stage and axillary lymph node involvement at the time of the initial diagnosis, treatment methods, hormone receptor status, and serum levels of the tumor markers CEA and CA 15.3. The data were processed and analysed using the SPSS statistical package. The statistical significance of differences between groups and subgroups was evaluated by x(2) Pearson's test and Student's paired t-test. Compared to sporadic cases, patients with familial breast cancer were more often diagnosed at an advanced III or IV stage; metastatic involvement of the regional lymph nodes was more frequent in group I patients. In the same group more radical surgical procedures combined with chemotherapy and local irradiation were performed. In group I the percentage of negative hormone receptors was higher (35.3% versus 22.6%; p result of their particular characteristics, these patients require more radical surgical techniques combined with pre- or postoperative local radiotherapy and systemic chemotherapy.

  8. Reproduction in the space environment: Part II. Concerns for human reproduction (United States)

    Jennings, R. T.; Santy, P. A.


    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.

  11. Professing faith, professing medicine: Physicians and the call to evangelize (United States)

    Bochanski, Philip G.


    The Hippocratic Oath traditionally establishes medicine as a profession: A career, or vocation based on the professing of an oath regarding personal and public behavior. For Catholic physicians, the commitments of the Oath of Hippocrates take on new meaning when seen in light of the promises made at Baptism and renewed every Easter. This paper, originally an address to medical students, considers the role of Catholic physicians as evangelizers, those who spread the message and values of the Gospel of Jesus Christ. PMID:24899735

  12. Self - care strategies among risky profession workers

    Directory of Open Access Journals (Sweden)

    Katarína Vasková


    Full Text Available Taking care of oneself is crucial for maintaining one´s psychical and physical health. In the context of risky profession this topic can play an even more important role, because it can be the source of necessary information for improvement of coping capacity when one is confronted with crisis situations. The aim of the present study is to identify the most common forms of self-care among selected risky professions. In the second part is the attention focused on the comparison of the specificities of risky to non-risky professions in self-care. Methods: For data collection Self-regulation Self-care Questionnaire by authors Hricová and Lovaš (in press is used. The sample consists of two groups. In the first one participated 156 respondents, who worked in risky professions - namely police officers (60 at the age between 22 to 55 years (average age is 36.88, SD=9.49, fire fighters (46 at the age between 22 to 62 years (average age is 35.13, SD=8.31 and paramedics (50 at the age between 25 to 55 years (average age is 40.3, SD=6.62. 76.2% of the sample are men, 19.0% are women and 4,8% didn´t state their gender. The second sample consists of 161 participants who work in administrative, industry production or IT sphere. They were at the age between 23 to 61 years (average age is 38.01, SD=10.45. 74% of the sample are men and 21.7% are women. Results and discussion: Results confirmed the dominance of psychological self-care above physical among risky professions. To the forefront gets the need to live meaningful life, to fully use one´s skills and to be satisfied with one´s life and decisions. All this needs can be assigned to the necessity of sense, which could be seen as a result of everyday contact with critical and life threaten situations. Equally important sphere of self-care is the necessity of high-quality relationships, which doesn´t mean only relationships with family or friends. It is important to highlight also relationships with

  15. Study of diffuse H II regions potentially forming part of the gas streams around Sgr A* (United States)

    Armijos-Abendaño, J.; López, E.; Martín-Pintado, J.; Báez-Rubio, A.; Aravena, M.; Requena-Torres, M. A.; Martín, S.; Llerena, M.; Aldás, F.; Logan, C.; Rodríguez-Franco, A.


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

  16. The 183-WSL Fast Rain Rate Retrieval Algorithm. Part II: Validation Using Ground Radar Measurements (United States)

    Laviola, Sante; Levizzani, Vincenzo


    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

  17. The new production theory for health care through clinical reengineering: a study of clinical guidelines--Part II. (United States)

    Sharp, J R


    In Part I of this two-part article, in the December 1994 issue of the journal, the author discussed the manufacturing theories of Peter Drucker in terms of their applicability for the health care field. He concluded that Drucker's four principles and practices of manufacturing--statistical quality control, manufacturing accounting, modular organization, and systems approach--do have application to the health care system. Clinical guidelines, a variation on the Drucker theory, are a specific example of the manufacturing process in health. The performance to date of some guidelines and their implications for the health care reform debate are discussed in Part II of the article.

    Adrian TOADER


    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.

    Ranganna, S; Govindarajan, V S; Ramana, K V


    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

    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)

  13. Technical Information on the Carbonation of the EBR-II Reactor, Summary Report Part 1: Laboratory Experiments and Application to EBR-II Secondary Sodium System

    Energy Technology Data Exchange (ETDEWEB)

    Steven R. Sherman


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

  16. Observance of hand washing procedures performed by the medical personnel after the patient contact. Part II. (United States)

    Garus-Pakowska, Anna; Sobala, Wojciech; Szatko, Franciszek


    The Centers for Disease Control and Prevention (CDC) as well as the World Health Organization (WHO) state that adequate hand hygiene maintained by medical personnel is an indispensable prerequisite for controlling nosocomial infections. The recommendations of CDC and WHO emphasize the obligation to wash hands after each contact with a patient, after the exposure to a potentially infectious material or upon the contact with objects surrounding the patient. The study was performed by quasi-observation among the group of 188 medical staff members (nurses and physicians) working in three selected hospitals of the Łódź Province. The procedure of hand washing/disinfection performed directly after the patient contact according to the recommendations of CDC and WHO was observed. The results were subject to statistical analysis (p hand washing were recorded. The medical personnel followed the hand hygiene procedures after the patient contact in 26.4% of the situations that require hygiene according to the guidelines. The level of observance of the hand washing procedures depended significantly on the type of performed activity, profession, degree of workload, index of activity, and time of duty hours. The mean time of hand washing after patient contact was 9.2 s for physicians and 6.7 s for nurses. Both the level of observance of hygienic procedures after the contact with patients as well as the time of hand washing are insufficient. There is an urgent need to work out educational programs on maintaining proper hand hygiene for medical personnel.

  17. THE FOOTWEAR DESIGNING SESSION USING CRISPIN DYNAMICS ENGINEER. PART II: Creating the parts, Estimating the material consumption, Grading

    Directory of Open Access Journals (Sweden)



    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.

    Part II of the guidelines contains a description of epidemiology, histopathology, clinical presentation, diagnostic procedure, treatment, and survival for each type of neuroendocrine tumour. We are not only including gastroenteropancreatic tumours but also bronchopulmonary and thymic neuroendocrine...... tumours. These guidelines essentially cover basic knowledge in the diagnosis and management of the different forms of neuroendocrine tumour. We have, however, tried to give more updated information about the epidemiology and histopathology, which is essential for the clinical management of these tumours....

  2. This new science of ours: a more or less systematic history of consciousness and transcendence. Part II. (United States)

    Tresan, David I


    Part I of this paper having postulated the locus of consciousness as residing in a field between primitive mind in participation mystique with the world and a transcendent ground of being, Part II takes up the nature of mind itself in this field in terms of in vivo experiences. Operations and manifestations of consciousness are inexhaustively explored in four venues: 1) Jung's life experiences, 2) Joseph Henderson's theory of psychic development, 3) Eric Voegelin's theory of consciousness and 4) the experiences of analytic patients in far reaches of very long analyses.

    HISTORY OF ROBOTICS: FROM ARCHYTAS OF TARENTUM UNTIL DA VINCI ROBOT. (PART II) Robotic surgery is a reality. In order to to understand how new robots work is interesting to know the history of ancient (see part i) and modern robotics. The desire to design automatic machines imitating humans continued for more than 4000 years. Archytas of Tarentum (at around 400 a.C.), Heron of Alexandria, Hsieh-Fec, Al-Jazari, Bacon, Turriano, Leonardo da Vinci, Vaucanson o von Kempelen were robot inventors. ...

  4. Evaluación neurofuncional del tallo cerebral Parte II: Reflejo mandibular = Neurofunctional evaluation of brain stem. II. Mandibular reflex

    Directory of Open Access Journals (Sweden)

    Leon Sarmiento, Fidias E.


    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.

  8. Strategic Petroleum Reserve (SPR) oil storage cavern sulphur mines 2-4-5 certification tests and analysis. Part I: 1981 testing. Part II: 1982 testing

    Energy Technology Data Exchange (ETDEWEB)

    Beasley, R.R.


    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.

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

    Energy Technology Data Exchange (ETDEWEB)

    Schwartz, J T


    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.

  11. A critical overview of non-aqueous capillary electrophoresis. Part II: separation efficiency and analysis time. (United States)

    Kenndler, Ernst


    A survey of the literature on non-aqueous capillary zone electrophoresis leaves one with the impression of a prevailing notion that non-aqueous conditions are principally more favorable than conventional aqueous media. Specifically, the application of organic solvents in capillary zone electrophoresis (CZE) is believed to provide the general advantages of superior separation efficiency, higher applicable electric field strength, and shorter analysis time. These advantages, however, are often claimed without providing any experimental evidence, or based on rather uncritical comparisons of limited sets of arbitrarily selected separation results. Therefore, the performance characteristics of non-aqueous vs. aqueous CZE certainly deserve closer scrutiny. The primary intention of Part II of this review is to give a critical survey of the literature on non-aqueous capillary electrophoresis (NACE) that has emerged over the last five years. Emphasis is mainly placed on those studies that are concerned with the aspects of plate height, plate number, and the crucial mechanisms contributing to zone broadening, both in organic and aqueous conditions. To facilitate a deeper understanding, this treatment covers also the theoretical fundamentals of peak dispersion phenomena arising from wall adsorption; concentration overload (electromigration dispersion); longitudinal diffusion; and thermal gradients. Theoretically achievable plate numbers are discussed, both under limiting (at zero ionic strength) and application-relevant conditions (at finite ionic strength). In addition, the impact of the superimposed electroosmotic flow contributions to overall CZE performance is addressed, both for aqueous and non-aqueous media. It was concluded that for peak dispersion due to wall adsorption and due to concentration overload (electromigration dispersion, leading to peak triangulation) no general conjunction with the solvent can be deduced. This is in contrast to longitudinal diffusion: the

  2. Sexology as a profession in France. (United States)

    Giami, Alain; de Colomby, Patrick


    A national survey of sexologists was carried out in France in 1998-1999, among the individuals listed in the professional directories and the telephone book as "sexologists." It described the sociodemographic characteristics of sexologists, their initial profession and training in sexology, sex therapy and psychotherapeutic techniques, and how they practice sexology. A total of 959 individuals were identified and surveyed. The response rate was 63%. Two thirds of the sexologists were physicians and 60% were men. French sexologists appeared to be segmented into three subgroups: (1) one-third were general practitioners, trained in sexology and psychotherapeutic approaches, recognized themselves as sexologists, and devoted 40% of their professional activity to sexology. Men were about two thirds of this group; (2) one-third were nonphysicians (including psychologists and other health professionals, such as social workers and nurses), recognized themselves as sex therapists and devoted one third of their time to sexology. Men and women were equally represented in this group; (3) one-third were specialists, with less training in sexology and psychotherapeutic techniques, and did not generally recognize themselves as sexologists. They devoted a lesser part of their time to sexology and had academic and hospital practice. Men comprised more than 75% of this group. This study raised the issue of the diversity of primary professions involved in the field of sexology and showed that sexology is a secondary professional choice for the majority of sexologists.

  3. Social circumstances and teaching profession

    Directory of Open Access Journals (Sweden)

    Beara Mirjana


    Full Text Available Teachers, as an element of the educational system, are considered to be the most important factor for improving the quality of work in schools. At the same time, schools and teachers, as well as the entire educational system, are functioning in the framework of broader social conditions that may be perceived as favorable and unfavorable for particular aspects of their job and profession. The paper examined teachers' perceptions of the social circumstances in which they work and professionally develop, as well as their temporal satisfaction of their profession and professional development. Temporal satisfaction involves cognitive evaluation of professional area of life through the prism of time (past, present, future. Examined was the interrelationship between these factors, as well as correlations with certain socio-demographic variables: length of employment, age, gender, initial education and type of school in which they are employed. Results indicate that teachers generally perceive social conditions as unfavorable to their professional development, being more satisfied with the past, than with the present and future professional aspects of life. Professional satisfaction was significantly correlated with the perception of social circumstances. Significant differences were established in the temporal satisfaction and perception of social conditions in relation to sex. Teachers in secondary vocational schools are more satisfied with their profession compared to teachers in gymnasiums and primary schools.

  11. Speech-language pathologists' views on attrition from the profession. (United States)

    McLaughlin, Emma; Lincoln, Michelle; Adamson, Barbara


    The aim of this study was to identify common themes in speech-language pathologists' perceptions of factors that increase and decrease their experiences of job stress, their satisfaction with their jobs and the profession, and their opinions about why people chose to leave the speech-language pathology profession. The participants' perceptions about the relationships between job stress, work satisfaction and job and profession retention were also explored. Sixty members of Speech Pathology Australia from a range of geographical and professional contexts were asked to participate in telephone interviews. Eighteen speech-language pathologists agreed to participate (30% response rate), and took part in semi-structured telephone interviews. Two researchers independently coded transcripts of the interviews for themes. Eight major themes were identified. These were positive aspects of the profession, workload, non-work obligations, effectiveness, recognition, support, learning and autonomy. The themes that emerged from analysis of these interviews provide new evidence about the positive and negative aspects of working as a speech-language pathologist, and provide preliminary insights into potential reasons as to why speech-language pathologists choose to remain in or leave the profession.

  12. Representations of the veterinary profession in nonfiction children's books. (United States)

    Amass, Sandra F


    To evaluate how the veterinary profession is represented in nonfiction children's books and determine whether representations reflect the current veterinary profession or the demographics of the United States. Survey. Covers of 46 nonfiction children's books and contents of 45 nonfiction children's books. Book covers and book contents (images and text) were evaluated for representations of veterinarians and to identify settings, clients, technology and equipment, and animals portrayed. Book contents were additionally evaluated to identify specialties and career opportunities specifically mentioned in the text. Book covers predominantly portrayed veterinarians as Caucasian women who wore examination coats, worked alone in veterinary clinics, and cared for dogs without a client present. Book contents predominantly portrayed veterinarians as a Caucasian man or woman who wore an examination coat, worked as part of a team in a veterinary clinic, and helped clients care for dogs, cats, and exotic animals. Specialties and career opportunities in the veterinary profession were mentioned in the text of 29 of 45 (64.4%) books. Nonfiction children's book covers that focused on the veterinary profession portrayed a greater percentage of women than is currently found in the profession. Similarly, books portrayed a greater percentage of Caucasians than in the current or predicted US population. With the exception of Asians, books collectively represented lower or similar percentages of underrepresented minorities, compared with the US population. Veterinarians are encouraged to select books for individual children that portray veterinarians with whom the children can identify.

  13. In vitro performance of Class I and II composite restorations: a literature review on nondestructive laboratory trials--part I. (United States)

    Dietschi, D; Argente, A; Krejci, I; Mandikos, M


    Posterior adhesive restorations are a basic procedure in general dental practices, but their application remains poorly standardized as a result of the number of available options. An abundant number of study hypotheses corresponding to almost unlimited combinations of preparation techniques, adhesive procedures, restorative options, and materials have been described in the literature and submitted to various evaluation protocols. A literature review was thus conducted on adhesive Class I and II restorations and nondestructive in vitro tests using the PubMed/Medline database for the 1995-2010 period. The first part of this review discusses the selected literature related to photoelasticity, finite element analysis (FEM), and microleakage protocols. Based on the aforementioned evaluation methods, the following parameters proved influential: cavity dimensions and design, activation mode (light or chemical), type of curing light, layering technique, and composite structure or physical characteristics. Photoelasticity has various limitations and has been largely (and advantageously) replaced by the FEM technique. The results of microleakage studies proved to be highly inconsistent, and the further use of this technique should be strictly limited. Other study protocols for adhesive Class II restorations were also reviewed and will be addressed in part II of this article, together with a tentative relevance hierarchy of selected in vitro methods.

    Crisma, Marco; De Zotti, Marta; Formaggio, Fernando; Peggion, Cristina; Moretto, Alessandro; Toniolo, Claudio


    In this second part of our review article on the preferred screw sense and interconversion of peptide helices, we discuss the most significant computational and experimental data published on helices formed by the most extensively investigated categories of noncoded α-amino acids. They are as follows: (i) N-alkylated Gly residues (peptoids), (ii) C(α) -alkylated α-amino acids, (iii) C(α,β) -sp(2) configurated α-amino acids, and (iv) combinations of residues of types (ii) and (iii). With confidence, the large body of interesting papers examined and classified in this editorial effort will stimulate the development of helical peptides in many diverse areas of biosciences and nanosciences.

  20. Transactive System: Part II: Analysis of Two Pilot Transactive Systems using Foundational Theory and Metrics

    Energy Technology Data Exchange (ETDEWEB)

    Lian, Jianming; Sun, Y; Kalsi, Karanjit; Widergren, Steven E.; Wu, Di; Ren, Huiying


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

  1. Arbitrary order 2D virtual elements for polygonal meshes: part II, inelastic problem (United States)

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


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

    Kushner, Harold J., E-mail: [Brown University, Applied Math (United States)


    This is the second part of a work dealing with key issues that have not been addressed in the modeling and numerical optimization of nonlinear stochastic delay systems. We consider new classes of models, such as those with nonlinear functions of several controls (such as products), each with is own delay, controlled random Poisson measure driving terms, admissions control with delayed retrials, and others. Part I was concerned with issues concerning the class of admissible controls and their approximations, since the classical definitions are inadequate for our models. This part is concerned with transportation equation representations and their approximations. Such representations of nonlinear stochastic delay models have been crucial in the development of numerical algorithms with much reduced memory and computational requirements. The representations for the new models are not obvious and are developed. They also provide a template for the adaptation of the Markov chain approximation numerical methods.

  4. A review of breast tomosynthesis. Part II. Image reconstruction, processing and analysis, and advanced applications (United States)

    Sechopoulos, Ioannis


    Many important post-acquisition aspects of breast tomosynthesis imaging can impact its clinical performance. Chief among them is the reconstruction algorithm that generates the representation of the three-dimensional breast volume from the acquired projections. But even after reconstruction, additional processes, such as artifact reduction algorithms, computer aided detection and diagnosis, among others, can also impact the performance of breast tomosynthesis in the clinical realm. In this two part paper, a review of breast tomosynthesis research is performed, with an emphasis on its medical physics aspects. In the companion paper, the first part of this review, the research performed relevant to the image acquisition process is examined. This second part will review the research on the post-acquisition aspects, including reconstruction, image processing, and analysis, as well as the advanced applications being investigated for breast tomosynthesis.

  5. Dental sequellae of alveolar clefts: utility of endosseous implants. Part II: clinical cases. (United States)

    Samama, Yves; Tulasne, Jean-François


    This second part follows on from part 1 published in the previous issue of this journal. The aim of this publication is to offer teams specializing in the primary and secondary treatment of labio-alveolar-palatal clefts a prosthetic evaluation for more rational management of the dental sequellae of clefts for patients who, when they reach adulthood, often wish to improve their facial esthetics, in which the dental element plays an important part. The reorganization and restoration of the maxillary anterior teeth and their esthetic integration with respect to the face and lips would then be less of a problem for plastic surgeons and orthodontists. In this regard, the installation in this sector of implants, following ambitious bone surgery involving the sacrifice of the teeth of the medial nasal process in bilateral forms, is a protocol that could usefully be taken into account.

  9. Extracranial tumor vascularity: determination by dynamic CT scanning. Part II. The unit approach

    Energy Technology Data Exchange (ETDEWEB)

    Som, P.M.; Lanzieri, C.F.; Sacher, M.; Lawson, W.; Biller, H.F.


    Twenty-eight patients had combined conventional drip infusion CT scans. The information about the anatomic location of the lesion, its configuration, its cross-sectional appearance, its vacularity (as determined by dynamic signature curves), and its clinical presentation were considered as a single overall unit. This diagnostic approach allowed a diagnosis to be made on virtually all of these enhancing lesions without resorting to either a digital venous imaging study or angiographic procedure. In 17 of these cases, such an invasive second procedure was performed either to confirm the CT impression as part of this study or as part of a therapeutic embolization procedure.

  11. A history of clinical psychology as a profession in America (and a glimpse at its future). (United States)

    Benjamin, Ludy T


    Clinical psychology emerged as a profession in the United States in the 1890s with studies conducted by psychologists with patients in the mental asylums of that time, and with the founding of Witmer's psychological clinic, where he treated children with learning and behavioral problems. This chapter traces the history of clinical psychology as a profession, from the focus on assessment at the turn of the twentieth century to the provision of psychotherapy that would come to dominate the field after World War II. It concludes with a discussion of some of the contemporary concerns in the profession and how those might impact the future practice of clinical psychologists.

  19. Elastic and Piezoelectric Properties of Boron Nitride Nanotube Composites. Part II; Finite Element Model (United States)

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


    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.

    Barizon, Karine T L; Bergeron, Cathia; Vargas, Marcos A; Qian, Fang; Cobb, Deborah S; Gratton, David G; Geraldeli, Saulo


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

  1. Imaging of juvenile spondyloarthritis. Part II: Ultrasonography and magnetic resonance imaging

    Directory of Open Access Journals (Sweden)

    Iwona Sudoł-Szopińska


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

    Power, Sarah


    Nanotechnology can be defined as the design, creation, and manipulation of structures on the nanometer scale. This two-part review is intended to acquaint the interventionalist with the field of nanotechnology, and provide an overview of potential applications, while highlighting advances relevant to interventional radiology. Part 2 of the article concentrates on drug delivery, thermotherapy, and vascular intervention. In oncology, advances in drug delivery allow for improved efficacy, decreased toxicity, and greater potential for targeted therapy. Magnetic nanoparticles show potential for use in thermotherapy treatments of various tumours, and the effectiveness of radiofrequency ablation can be enhanced with nanoparticle chemotherapy agents. In vascular intervention, much work is focused on prevention of restenosis through developments in stent technology and systems for localised drug delivery to vessel walls.

  10. Oral ulcers: clinical aspects. A tool for dermatologists. Part II. Chronic ulcers. (United States)

    Muñoz-Corcuera, M; Esparza-Gómez, G; González-Moles, M A; Bascones-Martínez, A


    Oral ulcers are generally painful lesions that are related to various conditions developing within the oral cavity. They can be classified as acute or chronic according to their presentation and progression. Acute oral ulcers are be associated with conditions such as trauma, recurrent aphthous stomatitis, Behçet's disease, bacterial and viral infections, allergic reactions or adverse drug reactions. Chronic oral ulcers are associated with conditions such as oral lichen planus, pemphigus vulgaris, mucosal pemphigoid, lupus erythematosus, mycosis and some bacterial and parasitic diseases. The correct differential diagnosis is necessary to establish the appropriate treatment, taking into account all the possible causes of ulcers in the oral cavity. In this second part of this two-part review, chronic oral ulcers are reviewed.

  11. Interview-Based Qualitative Research in Emergency Care Part II: Data Collection, Analysis and Results Reporting


    Ranney, Megan L.; Meisel, Zachary; Choo, Esther K.; Garro, Aris; Sasson, Comilla; Morrow, Kathleen


    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...

  13. How to succeed in science: a concise guide for young biomedical scientists. Part II: making discoveries. (United States)

    Yewdell, Jonathan W


    Making discoveries is the most important part of being a scientist, and also the most fun. Young scientists need to develop the experimental and mental skill sets that enable them to make discoveries, including how to recognize and exploit serendipity when it strikes. Here, I provide practical advice to young scientists on choosing a research topic, designing, performing and interpreting experiments and, last but not least, on maintaining your sanity in the process.

  14. Anti-Hypertensive Herbs and Their Mechanisms of Action: Part II (United States)

    Anwar, M. Akhtar; Al Disi, Sara S.; Eid, Ali H.


    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 (NO), vascular smooth muscle cell (VSMC) proliferation, hydrogen sulfide, nuclear factor kappa-B (NF-κB), 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.

  15. Environmental stressors and cardio-metabolic disease: part II-mechanistic insights. (United States)

    Münzel, Thomas; Sørensen, Mette; Gori, Tommaso; Schmidt, Frank P; Rao, Xiaoquan; Brook, Frank R; Chen, Lung Chi; Brook, Robert D; Rajagopalan, Sanjay


    Environmental factors can act as facilitators of chronic non-communicable diseases. Ambient noise and air pollution collectively outrank all other environmental risk factors in importance, contributing to over 75% of the disease and disability burden associated with known environmental risk factors. In the first part of this review, we discussed the global burden and epidemiologic evidence supporting the importance of these novel risk factors as facilitators of cardiometabolic disease. In this part, we will discuss pathophysiological mechanisms responsible for noise and air pollution-mediated effects. Akin to traditional cardiovascular risk factors, a considerable body of evidence suggests that these environmental agents induce low-grade inflammation, oxidative stress, vascular dysfunction, and autonomic nervous system imbalance, thereby facilitating the development of diseases such as hypertension and diabetes. Through their impact on traditional risk factors and via additional novel mechanisms, environmental risk factors may have much larger impact on cardiovascular events than currently appreciated. In the second part of this review, we discuss deficiencies and gaps in knowledge and opportunities for new research. © The Author 2016.

  16. The motion planning problem and exponential stabilization of a heavy chain. Part II

    Directory of Open Access Journals (Sweden)

    Piotr Grabowski


    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.

  17. PIO I-II tendencies case study. Part 1. Mathematical modeling

    Directory of Open Access Journals (Sweden)

    Adrian TOADER


    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.

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

  20. Information Extraction from Large-scale WSNs: Approaches and Research Issues Part II: Query-Based and Macroprogramming Approaches

    Directory of Open Access Journals (Sweden)

    Tessa DANIEL


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

  1. Preliminary list of deep borings in the United States Part II: Nebraska-Wyoming (United States)

    Darton, Nelson Horatio


    The wells and borings reported in the paper are all more than 400 feet in depth. The information concerning them has been obtained partly from replies to circular letters sent to all parts of the United States an  to lack of knowledge on the part of correspondents, and to the incompleteness of published records, doubtless there are borings which have not been reported. In regions of oil and gas wells, where borings are numerous, the individual wells can not be listed here, but representative wells are given. References to logs or records of the wells, or extended descriptions of them, are given in footnotes, and after the list of wells in each State there is added a list of the principal publications relating to deep borings in that state.The bearing of the information given in the columns of the lists probably is apparent, unless, perhaps, in the one headed "Height to which the water rises." In this column an entry such as "-45" indicates that the water rises to within 45 feet of the surface; "+45" indicates that it is a flowing well and has sufficient head to raise the water 45 feet above the surface in an open pipe 45 feet or more in height. The yield in gallons per minute usually is estimated. Depths and diameters often have been reported from memory, and different sources of publication sometimes give different figures. Most wells which are not stated to be "for oil," "for gas," "brine," "abandoned," etc., in the remarks column, or "not any" in the yield column, generally afford more or less water. Many of the gas and oil wells, active or abandoned, yield salt water.

  2. Review on health effects related to mobile phones. Part II: results and conclusions. (United States)

    Moussa, Mayada M R


    Part 1 of this review was published in the Journal of Egyptian Association of Public Health 2010; 85(5, 6):337-345. It included the introduction and methodology. It was based on reviewing the literature published in the last 10 years (2000-2010). Searches were made electronically through various search engines and health-related databases, and manually through journals, reports, and conference proceedings. The references used in the introduction of part 1 were mainly WHO reports, textbooks, and nonserial publications. In part 2, the literature published in 2011 was added to the yield and the results and conclusions are based on the updated search. In this literature search, 69 research articles (epidemiologic, experimental, cellular, and animal studies), 17 systemic or meta-analysis review studies, and four reports were included. The evidence presented in these peer-reviewed publications did not provide a consistent pattern that exposure to mobile phones is detrimental to health. Only studies associating mobile phone use during driving with road traffic accidents and those investigating electromagnetic interference with personal or hospital medical electronic devices showed consistent results. Regarding children, there are currently little data on cell phone use and health effects, including the risk of cancer. Further experimental and epidemiologic studies are needed to seek explanations for the controversies in studies on mobile phones so far. These studies should apply sound methodology for exposure assessment of mobile phone radiation and should focus on the effects of long-term use (more than 10 years). Cohort studies, in particular, should be established to investigate the long-term effects of mobile phone use on brain cancer as well as to investigate the possible health effects among children.

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

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


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

  4. Model-Based Assessment of Alternative Study Designs in Pediatric Trials. Part II: Bayesian Approaches. (United States)

    Smania, G; Baiardi, P; Ceci, A; Cella, M; Magni, P


    This study presents a pharmacokinetic-pharmacodynamic based clinical trial simulation framework for evaluating the performance of a fixed-sample Bayesian design (BD) and two alternative Bayesian sequential designs (BSDs) (i.e., a non-hierarchical (NON-H) and a semi-hierarchical (SEMI-H) one). Prior information was elicited from adult trials and weighted based on the expected similarity of response to treatment between the pediatric and adult populations. Study designs were evaluated in terms of: type I and II errors, sample size per arm (SS), trial duration (TD), and estimate precision. No substantial differences were observed between NON-H and SEMI-H. BSDs require, on average, smaller SS and TD compared to the BD, which, on the other hand, guarantees higher estimate precision. When large differences between children and adults are expected, BSDs can return very large SS. Bayesian approaches appear to outperform their frequentist counterparts in the design of pediatric trials even when little weight is given to prior information from adults. © 2016 The Authors CPT: Pharmacometrics & Systems Pharmacology published by Wiley Periodicals, Inc. on behalf of American Society for Clinical Pharmacology and Therapeutics.

  5. Thermomechanical Effects during Direct Chill and Electromagnetic Casting of Aluminum Alloys Part II : Numerical Simulation (United States)

    Drezet, J.-M.; Rappaz, M.; Krähenbühl, Y.

    The prediction of the ingot deformation during direct chill (DC) and electromagnetic (EM) casting of aluminum alloy slabs would allow the optimization of the mold/inductor shape capable of producing flat ingots. The transient thermomechanical model presented here predicts the deformation and the temperature field evolution during DC/EM casting. Deformation in the solid is assumed to obey a viscoplastic law. The model is validated on the basis of the measurements presented in part I. It enables to predict the influence of casting parameters on butt curl and swell, rolling faces pull-in and residual stress state for DC and EM-cast ingots.

    The present work represents a continuation of part I of this series of papers, in which we investigated the phenol yields in the OH-initiated oxidation of benzene under conditions of low to moderate concentrations of NOx, to elevated NOx levels. The products of the OH-initiated oxidation of benzene...... in 700 760 Torr of N-2/O-2 diluent at 297 +/- 4 K were investigated in 3 different photochemical reaction chambers. In situ spectroscopic techniques were employed for the detection of products, and the initial concentrations of benzene, NOx, and O-2 were widely varied (by factors of 6300, 1500, and 13...

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


    Michael, Louisa; Nikiforakis, Nikolaos


    We study effect of cavity collapse in non-ideal explosives as a means of controlling their sensitivity. The main aim is to understand the origin of localised temperature peaks (hot spots) that play a leading order role at early ignition stages. Thus, we perform 2D and 3D numerical simulations of shock induced single gas-cavity collapse in nitromethane. Ignition is the result of a complex interplay between fluid dynamics and exothermic chemical reaction. In part I of this work we focused on th...

  9. Thermal performance analysis and measurements of the prototype cryomodules of European XFEL accelerator-Part II (United States)

    Wang, X. L.; Barbanotti, S.; Eschke, J.; Jensch, K.; Klos, R.; Maschmann, W.; Petersen, B.; Sawlanski, O.


    Three accelerator prototype cryomodules (CMs) for the European XFEL have been produced, assembled and tested at DESY in a wide international collaboration. The heat load budget is a key element in the qualification of these CMs. We describe in this paper the measurements performed in the Cryomodule test bench (CMTB) to evaluate the thermal performances of the three prototype CMs. We present at first the methodology and instrumentation used for the measurements, then we analyse the main contributions to the heat loads at various temperature levels and finally we compare the measured values with the ones calculated and reported in the first part of this paper.

  10. Transonic Airfoil Flow Simulation. Part II: Inviscid-Viscous Coupling Scheme

    Directory of Open Access Journals (Sweden)

    Vladimir CARDOŞ


    Full Text Available A calculation method for the subsonic and transonic viscous flow over airfoil using the displacement surface concept is described. This modelling technique uses a finite volume method for the time-dependent Euler equations and laminar and turbulent boundary-layer integral methods. In additional special models for transition, laminar or turbulent separation bubbles and trailing edge treatment have been selected. However, the flow is limited to small parts of trailing edge-type separation. Comparisons with experimental data and other methods are shown.

    Kamińska Inez


    Full Text Available A refined model for elastoplastic damaged material is formulated based on the plastic potential introduced in Part I [1]. Considered model is an extension of Concrete Damaged Plasticity material implemented in Abaqus [2]. In the paper the stiffness tensor for elastoplastic damaged behaviour is derived. In order to validate the model, computations for the uniaxial tests are performed. Response of the model for various cases of parameter’s choice is shown and compared to the response of the CDP model.

  12. [Laboratory diagnostics of systemic autoimmune diseases. Part II: rheumatoid arthritis and vasculopathies]. (United States)

    Hartung, K; Seelig, H-P


    This is the second part in a series of articles on the laboratory diagnostics of rheumatic diseases. It addresses rheumatoid arthritis, systemic, anti-neutrophil cytoplasmatic antibody (ANCA) positive vasculitides and antiphospholipid-syndrome. The diagnostics of rheumatoid arthritis has been substantially improved by the recently introduced assay for antibodies against citrullinated peptides. In addition, a number of vasculitides can be differentiated by the presence of ANCA. Beta2-glycoprotein I antibodies and lupus anticoagulants are at present the most specific markers for antiphospholipid syndrome. Inflammatory activity can be monitored by determining the levels of acute phase proteins and erythrocyte sedimentation rate, but only in some situations by measuring immunoglobulins and interleukins.

  15. Resistance spot welding of galvanized steel: Part II. Mechanisms of spot weld nugget formation (United States)

    Gedeon, S. A.; Eagar, T. W.


    Dynamic inspection monitoring of the weld current, voltage, resistance, electrode displacement, and force was performed in conjunction with a detailed study of the effects of material variations and weld process parameter modifications on resistance spot welding of coated and uncoated steels. In order to determine the mechanisms of weld nugget formation and growth, scanning electron microscopy photos were taken of the developing nugget. These physical changes were then related to the dynamic inspection curves and the welding current lobe. The effects of material variations and weld process modifications, the results of which were presented in Part I, can be explained through an understanding of these mechanisms.

Firstly, we use the profession traits theory as a framework in arguing whether public health can be a legitimate profession in itself; secondly, we explain who public health professionals are and what usually is required for shaping the public health profession; and thirdly, we attempt to sketch the road to the authorisation or licensing of public health professionals. Finally, we propose some recommendations.

  18. Interaction of Zn(II) with hematite nanoparticles and microparticles: Part 2. ATR-FTIR and EXAFS study of the aqueous Zn(II)/oxalate/hematite ternary system. (United States)

    Ha, Juyoung; Trainor, Thomas P; Farges, François; Brown, Gordon E


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

  19. Differentially Encoded LDPC Codes—Part II: General Case and Code Optimization

    Directory of Open Access Journals (Sweden)

    Li (Tiffany Jing


    Full Text Available This two-part series of papers studies the theory and practice of differentially encoded low-density parity-check (DE-LDPC codes, especially in the context of noncoherent detection. Part I showed that a special class of DE-LDPC codes, product accumulate codes, perform very well with both coherent and noncoherent detections. The analysis here reveals that a conventional LDPC code, however, is not fitful for differential coding and does not, in general, deliver a desirable performance when detected noncoherently. Through extrinsic information transfer (EXIT analysis and a modified "convergence-constraint" density evolution (DE method developed here, we provide a characterization of the type of LDPC degree profiles that work in harmony with differential detection (or a recursive inner code in general, and demonstrate how to optimize these LDPC codes. The convergence-constraint method provides a useful extension to the conventional "threshold-constraint" method, and can match an outer LDPC code to any given inner code with the imperfectness of the inner decoder taken into consideration.

  20. Structural theory and thermoeconomic diagnosis Part II: Application to an actual power plant

    Energy Technology Data Exchange (ETDEWEB)

    Valero, A.; Lerch, F.; Serra, L.; Royo, J. [Univ Zaragoza, Zaragoza (Spain). Dept. of Mechanical Engineers


    In this second part of the paper, the new advances on thermoeconomic diagnosis presented in the part I are applied to the Escucha power plant, which is a 160 MW conventional coal fired power plant sited in Aragon (Spain). As a result the validity of the methodology is proved and quantified. The methodology is validated using a specific simulator of the Escucha power plant cycle. This simulator reproduces with high accuracy the cycle behavior for different operating conditions, either in design or in off design conditions. The error is lower than 1% in most of cases. The simulated results, i.e. temperatures pressures, mass flow rates, power and so on, are considered as plant measured and validated values thus avoiding measurement uncertainties. A complete thermoeconomic diagnosis is presented applying the Structural Theory of Thermoeconomics. The impact of the component inefficiencies on the fuel plant consumption, and the effect of a component inefficiency (intrinsic malfunction) on the rest of the plant components (induced malfunctions and dysfunctions), are analyzed and quantified. The methodology is validated quantifying its accuracy.

  1. Life-cycle analysis results for geothermal systems in comparison to other power systems: Part II.

    Energy Technology Data Exchange (ETDEWEB)

    Sullivan, J.L.; Clark, C.E.; Yuan, L.; Han, J.; Wang, M. (Energy Systems)


    A study has been conducted on the material demand and life-cycle energy and emissions performance of power-generating technologies in addition to those reported in Part I of this series. The additional technologies included concentrated solar power, integrated gasification combined cycle, and a fossil/renewable (termed hybrid) geothermal technology, more specifically, co-produced gas and electric power plants from geo-pressured gas and electric (GPGE) sites. For the latter, two cases were considered: gas and electricity export and electricity-only export. Also modeled were cement, steel and diesel fuel requirements for drilling geothermal wells as a function of well depth. The impact of the construction activities in the building of plants was also estimated. The results of this study are consistent with previously reported trends found in Part I of this series. Among all the technologies considered, fossil combustion-based power plants have the lowest material demand for their construction and composition. On the other hand, conventional fossil-based power technologies have the highest greenhouse gas (GHG) emissions, followed by the hybrid and then two of the renewable power systems, namely hydrothermal flash power and biomass-based combustion power. GHG emissions from U.S. geothermal flash plants were also discussed, estimates provided, and data needs identified. Of the GPGE scenarios modeled, the all-electric scenario had the highest GHG emissions. Similar trends were found for other combustion emissions.

  2. A Review of CAM for Procedural Pain in Infancy: Part II. Other Interventions

    Directory of Open Access Journals (Sweden)

    Jennie C. I. Tsao


    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.

  3. The available-enthalpy (flow-exergy) cycle. Part-II: applications to idealized baroclinic waves

    CERN Document Server

    Marquet, Pascal


    The local available-enthalpy cycle proposed in Part I of this paper is applied to document energetics of three numerical simulations, representing life cycles of idealized baroclinic waves. An improved temporal numerical scheme defined in Part I is used in this study, together with the Arpege-IFS model using a T42 triangular truncation. A 45{\\deg}N and 200 hPa dry unstable jet is constructed with the most unstable mode at zonal wave number 8. Energetic impacts of both horizontal and vertical diffusion schemes are determined separately. The role of ageostrophic winds within the Ekman layer is investigated, leading to an explanation for large observed values for the dissipation terms and to a new formulation of the potential-energy conversions. The magnitudes of these new conversion terms are compared with those of the usual barotropic and baroclinic conversions. A new version for the available-enthalpy cycle is proposed. It is suitable for open systems and it includes explicitly the potential-energy component ...

  4. New approach for a reliable in vitro sun protection factor method - Part II: Practical aspects and implementations. (United States)

    Miksa, S; Lutz, D; Guy, C; Delamour, E


    Our previous paper (Part I: Principle and mathematical aspects) presented a new reliable in vitro sun protection factor (SPF) method and demonstrated it to be reproducible and correlated with the in vivo method. Nevertheless, the relevance of an international method should to be adaptable to all products on the market and demonstrated with a blind test. Thus, the aim of this second article was to focus on the practical aspects and implementation (Part II) of a large population of different commercially available sunscreen formulations to obtain similar in vivo SPF results for the purpose of labelling. The method uses the spectroradiometric measurement of residual ultraviolet (UV) through the sample that was applied on a substrate with a robotic appliance. The method has been demonstrated to be highly reliable, and it is based on a multisubstrate solution with a single UV pre-irradiation dose. Furthermore, different categories of the product were studied to identify a reliable and universal in vitro SPF method. Based on different sunscreens products classified into 5 different groups (emulsion, oil, alcohol, stick and powder), it was demonstrated that our method has good reproducibility and accuracy compared with the clinical SPF method. Indeed, the mean coefficient of variation (CV%) was approximately 7%, and the coefficient of correlation reached approximately 0.8-1.0 for different types of tested products. Our second paper concludes that the new in vitro SPF method (based on 113 sunscreen products from the Parts I and II) is clearly adaptable for the SPF labelling purpose on any product type because it is non-invasive, less expensive, more practical and more reliable if performed under strict conditions. © 2016 Society of Cosmetic Scientists and the Société Française de Cosmétologie.

    This paper proposes the application of Direct Contact Membrane Distillation (DCMD) coupled with a nuclear reactor for water desalination and for low- and medium-level radioactive liquid waste concentration. Both laboratory and pilot plant experiments were carried out using the membranes reviewed in Part I of this paper. The effects of process parameters on the productivity and quality of DCMD systems are discussed. Distilled water, non-active solutions of inorganic salts and solutions with admixtures of radionuclides and simulated and real radioactive waste samples were used as feed solutions. Employing DCMD for liquid low- and medium-level radioactive waste processing is an alternative to traditional methods used in nuclear technology. The combination of radioactive waste processing and water desalination creates an economical integrated system for water and wastewater management in nuclear power plants. (author)

  6. Lead-acid batteries in micro-hybrid applications. Part II. Test proposal (United States)

    Schaeck, S.; Stoermer, A. O.; Albers, J.; Weirather-Koestner, D.; Kabza, H.

    In the first part of this work [1] selected key parameters for applying lead-acid (LA) batteries in micro-hybrid power systems (MHPS) were investigated. Main results are integrated in an accelerated, comprehensive test proposal presented here. The test proposal aims at a realistic representation of the pSoC operation regime, which is described in Refs. [1,6]. The test is designed to be sensitive with respect to dynamic charge acceptance (DCA) at partially discharged state (critical for regenerative braking) and the internal resistance at high-rate discharge (critical for idling stop applications). First results are presented for up-to-date valve-regulated LA batteries with absorbent glass mat (AGM) separators. The batteries are close to the limits of the first proposal of pass/fail-criteria. Also flooded batteries were tested; the first out of ten units failed already.

  7. Indo-Pacific variability on seasonal to multidecadal timescales. Part II: Multiscale atmosphere-ocean linkages

    CERN Document Server

    Giannakis, Dimitrios


    The coupled atmosphere-ocean variability of the Indo-Pacific on interannual to multidecadal timescales is investigated in a millennial control run of CCSM4 and in observations using a family of modes recovered in Part~I of this work from unprocessed SST data through nonlinear Laplacian spectral analysis (NLSA). It is found that ENSO and combination modes of ENSO with the annual cycle exhibit a seasonally synchronized southward shift of equatorial surface zonal winds and thermocline adjustment consistent with terminating El Nino and La Nina events. The surface wind patterns associated with these modes also generate teleconnections between the Pacific and Indian Oceans, leading to a pattern of SST anomalies characteristic of the Indian Ocean dipole. Fundamental and combination modes representing the tropospheric biennial oscillation (TBO) in CCSM4 are also found to be consistent with mechanisms for seasonally synchronized biennial variability of the Asian-Australian monsoon and Walker circulation.

  8. Models for Quarks and Elementary Particles. Part II: What is Mass?

    Directory of Open Access Journals (Sweden)

    Neumann U. K. W.


    Full Text Available It is extremely productive to give the resultant vector ( EV from the outer vector product (Part I of this article series a physical significance. The EV is assumed as electric flux < with the dimensions [Vm]. Based on Maxwell’s laws this develops into the idea of the magnetic monopole (MMP in each quark. The MMP can be brought in relation with the Dirac monopole. The massless MMP is a productive and important idea on the one hand to recognise what mass is and on the other hand to develop the quark structure of massless photon (-likes from the quark composition of the electron. Based on the experiments by Shapiro it is recognised that the sinusoidal oscillations of the quark can be spiralled in the photons. In an extreme case the spiralling of such a sinusoidal arc produces the geometric locus loop of a quark in a mass-loaded particle.

  9. Awake surgery between art and science. Part II: language and cognitive mapping. (United States)

    Talacchi, Andrea; Santini, Barbara; Casartelli, Marilena; Monti, Alessia; Capasso, Rita; Miceli, Gabriele


    Direct cortical and subcortical stimulation has been claimed to be the gold standard for exploring brain function. In this field, efforts are now being made to move from intraoperative naming-assisted surgical resection towards the use of other language and cognitive tasks. However, before relying on new protocols and new techniques, we need a multi-staged system of evidence (low and high) relating to each step of functional mapping and its clinical validity. In this article we examine the possibilities and limits of brain mapping with the aid of a visual object naming task and various other tasks used to date. The methodological aspects of intraoperative brain mapping, as well as the clinical and operative settings, were discussed in Part I of this review.

  11. An Update on the Hazards and Risks of Forensic Anthropology, Part II: Field and Laboratory Considerations. (United States)

    Roberts, Lindsey G; Dabbs, Gretchen R; Spencer, Jessica R


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

  12. Exhaust Gas Temperature Measurements in Diagnostics of Turbocharged Marine Internal Combustion Engines Part II Dynamic Measurements

    Directory of Open Access Journals (Sweden)

    Korczewski Zbigniew


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

  13. Validity of the clinical diagnostic criteria for vascular dementia: a critical review. Part II. (United States)

    Wiederkehr, Sandra; Simard, Martine; Fortin, Claudette; van Reekum, Robert


    This review is the second of a two-part series focusing on the validity of eight clinical criteria for vascular dementia. Sixteen studies were selected according to their purposes and quality of experimental design. The analysis revealed that criteria for vascular dementia are not interchangeable; the eight criteria sets yielded different sensitivity and specificity results, as well as marked variability in incidence, prevalence, and frequency rates. Although the State of California Alzheimer's Disease Diagnostic and Treatment Centers (ADDTC) were the most sensitive and useful criteria in clinical settings and the National Institute of Neurological Disorders and Stroke-Association Internationale pour la Recherche et l'Enseignement en Neurosciences (NINDS-AIREN) were the most specific and useful criteria in research, all criteria shared similar flaws. A definition of the cognitive syndrome, associated vascular causes or lesions, and methods of assessment should be clearly specified in the future. Suggestions for improvement are made.

  14. How Clean Are Hotel Rooms? Part II: Examining the Concept of Cleanliness Standards. (United States)

    Almanza, Barbara A; Kirsch, Katie; Kline, Sheryl Fried; Sirsat, Sujata; Stroia, Olivia; Choi, Jin Kyung; Neal, Jay


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

    Carrasco-Zuber, J E; Navarrete-Dechent, C; Bonifaz, A; Fich, F; Vial-Letelier, V; Berroeta-Mauriziano, D


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

    Mohr, Nicholas M; Smith-Coggins, Rebecca; Larrabee, Hollynn; Dyne, Pamela L; Promes, Susan B


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

  19. AICRG, Part II: Crestal bone loss associated with the Ankylos implant: loading to 36 months. (United States)

    Chou, Cherng-Tzeh; Morris, Harold F; Ochi, Shigeru; Walker, Lori; DesRosiers, Deborah


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

  20. Atmospheric corrosion tests along the Norwegian-Russian border. Part II

    Henriksen, J.F.; Mikhailov, A.A.


    A bilateral exposure programme was carried out along the Norwegian-Russian border in 1990-1991, 1992-1993 and 1993-1994 to evaluate quantitatively the effect of sulphur pollutants on the atmospheric corrosion of important materials in sub-arctic climate. The first part of the programme demonstrated that also in subarctic climate do metals corrode depending on the atmospheric corrosivity, and dose-response functions were derived which combined the effects of SO{sub 2} and time of wetness. The second part of the programme, which is described in this report, involved exposures of carbon steel, zinc and copper at two sites in Norway and three sites in Russia. It is concluded that the accelerated atmospheric corrosion of metals in regions along the border is mainly due to dry deposition of sulphur. At some sites, dry deposition of Cl contributes because of sea-salt aerosols. The corrosivity of acid precipitation is certain but could not be represented as a function because of the small differences observed in the pH values at the different sites. At all test sites the kinetics of corrosion of steel, zinc and copper are characterized by a reduced corrosion rate after one year of exposure. Time of wetness is an important parameter in predicting atmospheric corrosion of metals even on a regional scale. Hence, for monitoring and for trend-effect analysis, it is very important to determine the corrosivity of SO{sub 2} with time of wetness. In accordance with dose-response functions obtained, the yearly corrosion rate for steel and zinc are higher for the areas with higher amounts of dry deposition of Cl than for areas with analogous but only SO{sub 2}-containing atmosphere. 6 refs., 8 figs., 15 tabs.

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

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

  3. Understanding HIV infection for the design of a therapeutic vaccine. Part II: Vaccination strategies for HIV. (United States)

    de Goede, A L; Vulto, A G; Osterhaus, A D M E; Gruters, R A


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

    Full Text Available Apresentou-se, na Parte I desta pesquisa, o desenvolvimento de um modelo computacional denominado MCID, para suporte à tomada de decisão quanto ao planejamento e manejo de projetos de irrigação e/ou drenagem. Objetivou-se, na Parte II, testar e aplicar o MCID. No teste comparativo com o programa DRAINMOD, espaçamentos entre drenos, obtidos com o MCID, foram ligeiramente maiores ou idênticos. Os espaçamentos advindos com o MCID e o DRAINMOD foram consideravelmente maiores que os obtidos por meio de metodologias tradicionais de dimensionamento de sistemas de drenagem. A produtividade relativa total, YRT, obtida com o MCID foi, em geral, inferior à conseguida com o DRAINMOD, devido a diferenças de metodologia ao se estimar a produtividade da cultura em resposta ao déficit hídrico. Na comparação com o programa CROPWAT, obtiveram-se resultados muito próximos para (YRT e evapotranspiração real. O modelo desenvolvido foi aplicado para as condições do Projeto Jaíba, MG, para culturas perenes e anuais cultivadas em diferentes épocas. Os resultados dos testes e aplicações indicaram a potencialidade do MCID como ferramenta de apoio à decisão em projetos de irrigação e/ou drenagem.Part I of this research presented the development of a decision support model, called MCID, for planning and managing irrigation and/or drainage projects. Part II is aimed at testing and applying MCID. In a comparative test with the DRAINMOD model, drain spacings obtained with MCID were slightly larger or identical. The spacings obtained with MCID and DRAINMOD were considerably larger than those obtained through traditional methodologies of design of drainage systems. The relative crop yield (YRT obtained with MCID was, in general, lower than the one obtained with DRAINMOD due to differences in the estimate of crop response to water deficit. In comparison with CROPWAT, very close results for YRT and for actual evapotranspiration were obtained. The

  6. Distribution function approach to redshift space distortions. Part II: N-body simulations (United States)

    Okumura, Teppei; Seljak, Uroš; McDonald, Patrick; Desjacques, Vincent


    Measurement of redshift-space distortions (RSD) offers an attractive method to directly probe the cosmic growth history of density perturbations. A distribution function approach where RSD can be written as a sum over density weighted velocity moment correlators has recently been developed. In this paper we use results of N-body simulations to investigate the individual contributions and convergence of this expansion for dark matter. If the series is expanded as a function of powers of μ, cosine of the angle between the Fourier mode and line of sight, then there are a finite number of terms contributing at each order. We present these terms and investigate their contribution to the total as a function of wavevector k. For μ2 the correlation between density and momentum dominates on large scales. Higher order corrections, which act as a Finger-of-God (FoG) term, contribute 1% at k ~ 0.015hMpc-1, 10% at k ~ 0.05hMpc-1 at z = 0, while for k > 0.15hMpc-1 they dominate and make the total negative. These higher order terms are dominated by density-energy density correlations which contributes negatively to the power, while the contribution from vorticity part of momentum density auto-correlation adds to the total power, but is an order of magnitude lower. For μ4 term the dominant term on large scales is the scalar part of momentum density auto-correlation, while higher order terms dominate for k > 0.15hMpc-1. For μ6 and μ8 we find it has very little power for k < 0.15hMpc-1, shooting up by 2-3 orders of magnitude between k < 0.15hMpc-1 and k < 0.4hMpc-1. We also compare the expansion to the full 2-d Pss(k,μ), as well as to the monopole, quadrupole, and hexadecapole integrals of Pss(k,μ). For these statistics an infinite number of terms contribute and we find that the expansion achieves percent level accuracy for kμ < 0.15hMpc-1 at 6-th order, but breaks down on smaller scales because the series is no longer perturbative. We explore resummation of the terms into

Until recently, the treatment of dry eye syndrome involves the use tearsubstitude therapy. Ten or fifteen years ago, 2–3 tearsubstitudes were presented at the domestic market. Currently, there are doses of different forms of artificial tears, while there are hundreds of them on the western pharmaceutical market. The rapid development in the search for new forms tearsubstitudes is not accident. This is due to the increasing number of patients suffering from disorders of the tear membrane stability, which achieves, according to different sources, up to 40–60% of the adult population. It should be noted that the primary cause of dry eye syndrome in 85–95% of patients is meibomian gland’s dysfunction, thus applying tearsubstitudes symptomatic therapy is treatment that does not solve the problem on the pathogenic level. For this reason, conducting therapeutic hygiene century (warm compresses + self-massage is an important component of the treatment of this group of patients. Objective evidence of relevance and effectiveness of therapeutic care age, in our opinion, is the rapid development of the pharmaceutical market in this area. There is a large number of new gels, lotions, wipes and other products for hygiene century every year. Clear algorithms that include therapeutic hygiene century (dates, the indications for the use of certain hygiene products is an actual

  8. Color stability and colorant effect on maxillofacial elastomers. Part II: weathering effect on physical properties. (United States)

    Haug, S P; Moore, B K; Andres, C J


    The clinical life of a maxillofacial prosthesis averages about 6 months, before it needs to be refabricated. Degradation of the color and physical properties of the prosthesis are the principle reasons for replacement. This second part of a 3-part in vitro investigation evaluated the change in physical properties of popular colorant-elastomer combinations as a result of weather exposure. Fifteen dumbbell-shaped and 15 trouser-shaped specimens were fabricated for each of the 3 elastomers (Silastic medical adhesive type A, Silastic 4-4210, and Silicone A-2186) and 6 colorant combinations (dry earth pigments, rayon fiber flocking, artist's oil paints, kaolin, liquid cosmetics, and no-colorants) for a total of 540 specimens. The 15 dumbbell-shaped and trouser-shaped specimens of each elastomer colorant combination were separated into 5 of each shape among 3 test condition groups (control, time passage, and natural weathering). Control specimens were evaluated within 1 month of fabrication. The time passage group was sealed in glass containers and kept in the dark for 6 months before testing. The natural-weathering groups were placed on the roof of the dental school for 6 months and exposed to sunlight and weathering. Evaluations of hardness and tear strength were made on trouser-shaped specimens, and evaluations of the ultimate tensile strength and percentage elongation on dumbbell-shaped specimens. Physical property data for each elastomer-colorant combination were subjected to a 1-way analysis of variance to examine effects among the test conditions. When significant differences were observed, the Student-Newman-Keuls multiple range test was performed to identify differences in elastomer-colorant combinations among each test condition at a significance level of .05. Exposure to weathering and time changes of the physical properties of many colorant-elastomer combinations indicated that properties of a clinical prosthesis can change with time. The addition of

  9. A relaxation-projection method for compressible flows. Part II: Artificial heat exchanges for multiphase shocks (United States)

    Petitpas, Fabien; Franquet, Erwin; Saurel, Richard; Le Metayer, Olivier


    The relaxation-projection method developed in Saurel et al. [R. Saurel, E. Franquet, E. Daniel, O. Le Metayer, A relaxation-projection method for compressible flows. Part I: The numerical equation of state for the Euler equations, J. Comput. Phys. (2007) 822-845] is extended to the non-conservative hyperbolic multiphase flow model of Kapila et al. [A.K. Kapila, Menikoff, J.B. Bdzil, S.F. Son, D.S. Stewart, Two-phase modeling of deflagration to detonation transition in granular materials: reduced equations, Physics of Fluids 13(10) (2001) 3002-3024]. This model has the ability to treat multi-temperatures mixtures evolving with a single pressure and velocity and is particularly interesting for the computation of interface problems with compressible materials as well as wave propagation in heterogeneous mixtures. The non-conservative character of this model poses however computational challenges in the presence of shocks. The first issue is related to the Riemann problem resolution that necessitates shock jump conditions. Thanks to the Rankine-Hugoniot relations proposed and validated in Saurel et al. [R. Saurel, O. Le Metayer, J. Massoni, S. Gavrilyuk, Shock jump conditions for multiphase mixtures with stiff mechanical relaxation, Shock Waves 16 (3) (2007) 209-232] exact and approximate 2-shocks Riemann solvers are derived. However, the Riemann solver is only a part of a numerical scheme and non-conservative variables pose extra difficulties for the projection or cell average of the solution. It is shown that conventional Godunov schemes are unable to converge to the exact solution for strong multiphase shocks. This is due to the incorrect partition of the energies or entropies in the cell averaged mixture. To circumvent this difficulty a specific Lagrangian scheme is developed. The correct partition of the energies is achieved by using an artificial heat exchange in the shock layer. With the help of an asymptotic analysis this heat exchange takes a similar form as

  10. The 29 June 2000 Supercell Observed during STEPS. Part II: Lightning and Charge Structure. (United States)

    Wiens, Kyle C.; Rutledge, Steven A.; Tessendorf, Sarah A.


    This second part of a two-part study examines the lightning and charge structure evolution of the 29 June 2000 tornadic supercell observed during the Severe Thunderstorm Electrification and Precipitation Study (STEPS). Data from the National Lightning Detection Network and the New Mexico Tech Lightning Mapping Array (LMA) are used to quantify the total and cloud-to-ground (CG) flash rates. Additionally, the LMA data are used to infer gross charge structure and to determine the origin locations and charge regions involved in the CG flashes. The total flash rate reached nearly 300 min-1 and was well correlated with radar-inferred updraft and graupel echo volumes. Intracloud flashes accounted for 95% 100% of the total lightning activity during any given minute. Nearly 90% of the CG flashes delivered a positive charge to ground (+CGs). The charge structure during the first 20 min of this storm consisted of a midlevel negative charge overlying lower positive charge with no evidence of an upper positive charge. The charge structure in the later (severe) phase was more complex but maintained what could be roughly described as an inverted tripole, dominated by a deep midlevel (5 9 km MSL) region of positive charge. The storm produced only two CG flashes (both positive) in the first 2 h of lightning activity, both of which occurred during a brief surge in updraft and hail production. Frequent +CG flashes began nearly coincident with dramatic increases in storm updraft, hail production, total flash rate, and the formation of an F1 tornado. The +CG flashes tended to cluster in or just downwind of the heaviest precipitation, which usually contained hail. The +CG flashes all originated between 5 and 9 km MSL, centered at 6.8 km (-10°C), and tapped LMA-inferred positive charge both in the precipitation core and (more often) in weaker reflectivity extending downwind. All but one of the -CG flashes originated from >9 km MSL and tended to strike near the precipitation core.

  11. Intra-abdominal adhesions in ultrasound. Part II: The morphology of changes

    Directory of Open Access Journals (Sweden)

    Andrzej Smereczyński


    Full Text Available Despite their frequent appearance, intra-abdominal adhesions are rarely the subject of clinical studies and academic discussions. For many years the operators have been trying to reduce such unfavourable consequences of interventions in the abdominal structures. The aim of this article is to present the possibilities of intra-abdominal adhesion diagnostics by means of ultrasound imaging based on authors’ own experience and information included in pertinent literature. The anatomy and examination technique of the abdominal wall were discussed in Part I of the article. In order to evaluate intraperitoneal adhesions, one should use a convex transducer with the frequency of 3.5–6 MHz. The article provides numerous examples of US images presenting intra-abdominal adhesions, particularly those which appeared after surgical procedures. The significance of determining their localisation and extensiveness prior to a planned surgical treatment is emphasized. Four types of morphological changes in the ultrasound caused by intra-abdominal adhesions are distinguished and described: visceroperitoneal adhesions, intraperitoneal adhesions, adhesive obstructions as well as adhesions between the liver and abdominal wall with a special form of such changes, i.e. hepatic pseudotumour. Its ultrasound features are as follows: 1. The lesion is localised below the scar in the abdominal wall after their incision. 2. The lesion is localised in the abdominal part of the liver segments III, IV and V. 3. With the US beam focus precisely set, the lack of fascia – peritoneum complex may be noticed. An uneven liver outline or its ventral displacement appears. 4. A hepatic adhesion-related pseudotumour usually has indistinct margins, especially the posterior one, and, gradually, from top to bottom, loses its hypoechogenic nature. 5. In a respiration test, this liver fragment does not present the sliding movement – a neoplastic tumour rarely shows such an effect

  12. Probabilistic evidential assessment of gunshot residue particle evidence (Part II): Bayesian parameter estimation for experimental count data. (United States)

    Biedermann, A; Bozza, S; Taroni, F


    Part I of this series of articles focused on the construction of graphical probabilistic inference procedures, at various levels of detail, for assessing the evidential value of gunshot residue (GSR) particle evidence. The proposed models--in the form of Bayesian networks--address the issues of background presence of GSR particles, analytical performance (i.e., the efficiency of evidence searching and analysis procedures) and contamination. The use and practical implementation of Bayesian networks for case pre-assessment is also discussed. This paper, Part II, concentrates on Bayesian parameter estimation. This topic complements Part I in that it offers means for producing estimates usable for the numerical specification of the proposed probabilistic graphical models. Bayesian estimation procedures are given a primary focus of attention because they allow the scientist to combine (his/her) prior knowledge about the problem of interest with newly acquired experimental data. The present paper also considers further topics such as the sensitivity of the likelihood ratio due to uncertainty in parameters and the study of likelihood ratio values obtained for members of particular populations (e.g., individuals with or without exposure to GSR).

  13. A synthesis of the effects of occupational therapy for persons with stroke, Part II: Remediation of impairments. (United States)

    Ma, Hui-ing; Trombly, Catherine A


    This article is the second of a two-part synthesis of research regarding the effects of occupational therapy to improve activity and participation and to reduce impairment for persons with stroke. Part I synthesized research findings for restoration of role participation and activity performance. Part II synthesizes research findings regarding the effects of occupational therapy to remediate psychosocial, cognitive-perceptual, and sensorimotor impairments. Only 29 studies involving 832 participants (mean age = 64.3 years) addressed these goals. No studies directly researched the effects of occupational therapy on depression after stroke. Eight studies addressed cognitive-perceptual abilities. The findings indicated that homemaking tasks resulted in greater improvement of cognitive ability than paper-and-pencil drills and that tasks that forced awareness of neglected space, including movement of the opposite limb into that space, improved unilateral neglect. Fifteen studies examined the effect of occupational therapy on various motor capacities after stroke. Coordinated movement improved under these conditions: (a) following written and illustrated guides for movement exercises, (b) using meaningful goal objects as targets, (c) practicing movements with specific goals, (d) moving both arms simultaneously but independently, and (e) imagining functional use of the affected limb. Research on inhibitory splinting was inconclusive. Based on these few studies and lack of replication, we could make only tentative recommendations for practice. Further definitive research is needed.

  14. An Electromagnetic Sensor for the Autonomous Running of Visually Impaired and Blind Athletes (Part II: The Wearable Device). (United States)

    Pieralisi, Marco; Di Mattia, Valentina; Petrini, Valerio; De Leo, Alfredo; Manfredi, Giovanni; Russo, Paola; Scalise, Lorenzo; Cerri, Graziano


    Currently, the availability of technology developed to increase the autonomy of visually impaired athletes during sports is limited. The research proposed in this paper (Part I and Part II) focuses on the realization of an electromagnetic system that can guide a blind runner along a race track without the need for a sighted guide. In general, the system is composed of a transmitting unit (widely described in Part I) and a receiving unit, whose components and main features are described in this paper. Special attention is paid to the definition of an electromagnetic model able to faithfully represent the physical mechanisms of interaction between the two units, as well as between the receiving magnetic sensor and the body of the user wearing the device. This theoretical approach allows for an estimation of the signals to be detected, and guides the design of a suitable signal processing board. This technology has been realized, patented, and tested with a blind volunteer with successful results and this paper presents interesting suggestions for further improvements.

  15. Failure analysis of leakage on titanium tubes within heat exchangers in a nuclear power plant. Part II: Mechanical degradation

    Energy Technology Data Exchange (ETDEWEB)

    Gong, Y.; Yang, Z.G. [Department of Materials Science, Fudan University, Shanghai (China); Yuan, J.Z. [Third Qinshan Nuclear Power Co. Ltd., Haiyan, Zhejiang Province (China)


    Serious failure incidents like clogging, quick thinning, and leakage frequently occurred on lots of titanium tubes of heat exchangers in a nuclear power plant in China. In the Part I of the whole failure analysis study with totally two parts, factors mainly involving three kinds of electrochemical corrosions were investigated, including galvanic corrosion, crevice corrosion, and hydrogen-assisted corrosion. In the current Part II, through microscopically analyzing the ruptures on the leaked tubes by scanning electron microscopy (SEM) and energy dispersive spectrometry (EDS), another four causes dominantly lying in the aspect of mechanical degradation were determined - clogging, erosion, mechanical damaging, and fretting. Among them, the erosion effect was the primary one, thus the stresses it exerted on the tube wall were also supplementarily evaluated by finite element method (FEM). Based on the analysis results, the different degradation extents and morphologies by erosion on the tubes when they were clogged by different substances such as seashell, rubber debris, and sediments were compared, and relevant mechanisms were discussed. Finally, countermeasures were put forward as well. (Copyright copyright 2012 WILEY-VCH Verlag GmbH and Co. KGaA, Weinheim)

  16. Capsicum--production, technology, chemistry, and quality--Part II. Processed products, standards, world production and trade. (United States)

    Govindarajan, V S


    Capsicums, as a spice, have been known since the beginning of civilization and historically associated with the discovery of the New World. The genus Capsicum (Fam. Solanaceae) provides many varieties and adds color, pungency, and aroma to the cuisines of most of the world. From the pungent chilli, of interest also to pharmaceuticals, to the colorful paprika and the bell capsicums with its remarkable aroma, the genus has been of great interest for its chemistry and physiological action. Pungency as a sensory attribute, its evaluation, structure-activity relationship, and its increasing acceptance and preference by diverse populations of the world are of great interest to many research disciplines. In a comprehensive review of all aspects in four sequential parts, Part I deals with History, Botany, Cultivation, and Primary Processing (CRC Critical Review, Food Science and Nutrition). The Capsicums among the spices are second only to black pepper in trades both in volume and value. The production of the different forms of this spice as ground, specialty seasonings, and as the concentrated oleoresins through technologically advanced processes, proposed newer products, the standard to control quality of the different products, world production, trade, and prospects are reviewed in detail in this, Part II.

  17. Sub-impacts of simply supported beam struck by steel sphere—part II: Numerical simulations

    Directory of Open Access Journals (Sweden)

    Xiaoli Qi


    Full Text Available This part of the article describes numerical simulations of the problem investigated experimentally. A three-dimensional finite element model of elastic–plastic for sphere falling on beam has been implemented using the nonlinear dynamic finite element software LS-DYNA. From the numerical simulations, it was found that the LS-DYNA is suitable to study complex sub-impact phenomenon, and good agreement is in general obtained between the simulation and experimental results. The numerical simulations show that the initial impact velocity, equivalent elasticity modulus, contact curvature radius of the sphere, and equivalent mass have great influence on the contact–impact time of the sub-impact, and an applicable range of the theoretical expression of contact–impact time of the sub-impact was determined. In addition, the numerical simulations demonstrate the ratios of maximum amplitudes of the first-, second-, and third-order vibrations to the maximum amplitudes of the beam vibrations, and the phase angle of the first-order vibration will change suddenly when the sub-impacts occur. Furthermore, the occurrence conditions of the sub-impacts were clarified numerically. It was found that the occurrence conditions of the sub-impacts can be represented by a mass ratio threshold, and the thickness or length of the beam has also a great influence on the occurrence of the sub-impacts. Once the sub-impacts occur, which would result in an uncertain behavior of the apparent coefficient of restitution.

  18. Epidemiology of burns throughout the World. Part II: intentional burns in adults. (United States)

    Peck, Michael D


    A significant number of burns and deaths from fire are intentionally wrought. Rates of intentional burns are unevenly distributed throughout the world; India has a particularly high rate in young women whereas in Europe rates are higher in men in mid-life. Data from hospitalized burn patients worldwide reveal incidence rates for assault by fire and scalds ranging from 3% to 10%. The average proportion of the body surface area burned in an assault by fire or scalds is approximately 20%. In different parts of the world, attempted burning of others or oneself can be attributed to different motives. Circumstances under which assaults occur fall largely into the categories of interpersonal conflict, including spousal abuse, elder abuse, or interactions over contentious business transactions. Contributing social factors to assaults by burning include drug and alcohol abuse, non-constructive use of leisure time, non-participation in religious and community activities, unstable relationships, and extramarital affairs. Although the incidence of self-mutilation and suicide attempts by burning are relatively low, deliberate self-harm carries a significant risk of death, with an overall mortality rate of 65% worldwide. In those who resort to self-immolation, circumstantial themes reflect domestic discord, family dysfunction, and the social ramifications of unemployment. Preventing injurious burn-related violence requires a multifaceted approach, including legislation and enforcement, education, and advocacy. Better standardized assessment tools are needed to screen for risks of abuse and for psychiatric disorders in perpetrators. Copyright © 2012 Elsevier Ltd and ISBI. All rights reserved.

  19. Long-Term Surgical Complications in the Oral Cancer Patient: a Comprehensive Review. Part II

    Directory of Open Access Journals (Sweden)

    Antonia Kolokythas


    Full Text Available Objectives: Surgery remains the preferred treatment for the majority of oral cancers. The aim of the present article was to provide a comprehensive review of complications associated with surgical treatment of oral cancer including hardware failure; complications associated with choice of reconstruction, donor site morbidity as well as functional and aesthetic issues that impact on the quality of life.Material and Methods: The available English language literature relevant to complications associated with surgical treatment of oral cancer was reviewed. Complications associated with potential for disfigurement, choice of reconstruction, donor site morbidity as well as functional and aesthetic issues that impact on the quality of life are summarized.Results: In total 35 literature sources were obtained and reviewed. The topics covered in the second part of this review series include hardware failure, scars and fistula formation; complications associated with choice of reconstruction, donor site morbidity as well as functional and aesthetic issues.Conclusions: Cancer resection should be planned around two very important concepts. First and foremost is the eradication of disease. This should be the ultimate goal of the ablative team and all potential complications that may be the result of appropriately executed oncologic resection should be discussed in details with the patient. Adequate reconstruction of the defects with restoration of form and function is the second, but not of less importance, goal for the successful care of the head and neck cancer patient.

  20. Small molecule HIV entry inhibitors: Part II. Attachment and fusion inhibitors: 2004-2010. (United States)

    Singh, Inder Pal; Chauthe, Siddheshwar Kisan


    The first US FDA approved HIV entry inhibitor drug Enfuvirdine belongs to the fusion inhibitor category. Earlier efforts in this area were focused on peptides and monoclonal antibodies; recently, the focus has shifted towards the development of small molecule HIV attachment and fusion inhibitors. They can be used for prophylactic purposes and also hold potential for the development of HIV microbicides. In a previous paper ('Small molecule HIV entry inhibitors: Part I'), we reviewed patents and patent applications for small molecule chemokine receptor antagonists from major pharmaceutical companies. In this paper, the development of small molecule HIV attachment and fusion inhibitors is discussed in detail. It covers patents and patent applications for small molecule HIV attachment and fusion inhibitors published between 2004 and 2010 and related literature with a focus on recent developments based on lead generation and lead modification. To augment the potency of currently available antiretroviral drug combinations and to fight drug-resistant virus variants, more effective drugs which target additional steps in the viral replication cycle are urgently needed. HIV attachment and fusion processes are such targets. Inhibitors of these targets will provide additional options for the treatment of HIV drug-resistant strains. Small molecule HIV attachment inhibitors such as BMS-378806 and analogs from Bristol Myers Squibb, N-aryl piperidine derivatives from Propharmacon, and NBD-556 and NBD-557 from New York Blood Center may have potential as vaginal microbicidal agents and can be an economical alternative to monoclonal antibodies.

  1. [History of robotics: from archytas of tarentum until Da Vinci robot. (Part II)]. (United States)

    Sánchez-Martín, F M; Jiménez Schlegl, P; Millán Rodríguez, F; Salvador-Bayarri, J; Monllau Font, V; Palou Redorta, J; Villavicencio Mavrich, H


    Robotic surgery is a reality. In order to to understand how new robots work is interesting to know the history of ancient (see part i) and modern robotics. The desire to design automatic machines imitating humans continued for more than 4000 years. Archytas of Tarentum (at around 400 a.C.), Heron of Alexandria, Hsieh-Fec, Al-Jazari, Bacon, Turriano, Leonardo da Vinci, Vaucanson o von Kempelen were robot inventors. At 1942 Asimov published the three robotics laws. Mechanics, electronics and informatics advances at XXth century developed robots to be able to do very complex self governing works. At 1985 the robot PUMA 560 was employed to introduce a needle inside the brain. Later on, they were designed surgical robots like World First, Robodoc, Gaspar o Acrobot, Zeus, AESOP, Probot o PAKI-RCP. At 2000 the FDA approved the da Vinci Surgical System (Intuitive Surgical Inc, Sunnyvale, CA, USA), a very sophisticated robot to assist surgeons. Currently urological procedures like prostatectomy, cystectomy and nephrectomy are performed with the da Vinci, so urology has become a very suitable speciality to robotic surgery.

  2. Fundamentals in Biostatistics for Investigation in Pediatric Dentistry: Part II -Biostatistical Methods. (United States)

    Pozos-Guillén, Amaury; Ruiz-Rodríguez, Socorro; Garrocho-Rangel, Arturo

    The main purpose of the second part of this series was to provide the reader with some basic aspects of the most common biostatistical methods employed in health sciences, in order to better understand the validity, significance and reliability of the results from any article on Pediatric Dentistry. Currently, as mentioned in the first paper, Pediatric Dentists need basic biostatistical knowledge to be able to apply it when critically appraise a dental article during the Evidence-based Dentistry (EBD) process, or when participating in the development of a clinical study with dental pediatric patients. The EBD process provides a systematic approach of collecting, review and analyze current and relevant published evidence about oral health care in order to answer a particular clinical question; then this evidence should be applied in everyday practice. This second report describes the most commonly used statistical methods for analyzing and interpret collected data, and the methodological criteria to be considered when choosing the most appropriate tests for a specific study. These are available to Pediatric Dentistry practicants interested in reading or designing original clinical or epidemiological studies.

  3. On the source inversion of fugitive surface layer releases. Part II. Complex sources (United States)

    Sanfélix, V.; Escrig, A.; López-Lilao, A.; Celades, I.; Monfort, E.


    The experimental measurement of fugitive emissions of particulate matter entails inherent complexity because they are usually discontinuous, of short duration, may be mobile, and are affected by weather conditions. Owing to this complexity, instead of experimental measurements, emission factors are used to inventory such emissions. Unfortunately, emission factor datasets are still very limited at present and are insufficient to identify problematic operations and appropriately select control measures. To extend these datasets, a source inversion methodology (described in Part I of this work) was applied to field campaigns in which operation-specific fugitive particulate matter emission factors were determined for several complex fugitive sources, some of which were mobile. Mobile sources were treated as a superposition of instantaneous sources. The experimental campaigns were conducted at ports (bulk solids terminals), aggregate quarries, and cement factories, encompassing powder handling operations and vehicle circulation on paved and unpaved roads. Emission factors were derived for the operations and materials involved in these scenarios and compared with those available in the emission factor compilations. Significant differences were observed between the emission factors obtained in the studied handling operations. These differences call into question the use of generic emission factors and highlight the need for more detailed studies in this field.

  4. Atmospheric amines - Part II. Thermodynamic properties and gas/particle partitioning (United States)

    Ge, Xinlei; Wexler, Anthony S.; Clegg, Simon L.


    Amines enter the atmosphere from a wide range of sources, but relatively little is known about their atmospheric behavior, especially their role in gas/particle partitioning. In Part I of this work ( Ge et al., 2011) a total of 154 amines, 32 amino acids and urea were identified as occurring in the atmosphere, based upon a survey of the literature. In this work we compile data for the thermodynamic properties of the amines which control gas/particle partitioning (Henry's Law constant, liquid vapor pressure, acid dissociation constant, activity coefficient and solubility in water), and also estimate the solid/gas dissociation constants of their nitrate and chloride salts. Prediction methods for boiling point, liquid vapor pressure, acid dissociation constant and the solubility of the amines in water are evaluated, and used to estimate values of the equilibrium constants where experimental data are lacking. Partitioning of amines into aqueous aerosols is strongly dependent upon pH and is greatest for acidic aerosols. For several common amines the tendency to partition to the particle phase is similar to or greater than that of ammonia. Our results are presented as tables of values of thermodynamic equilibrium constants, which are also incorporated into the Extended Aerosol Inorganics Model ( E-AIM, to enable gas/aerosol partitioning and other calculations to be carried out.

  5. Coupled Cluster in Condensed Phase. Part II: Liquid Hydrogen Fluoride from Quantum Cluster Equilibrium Theory. (United States)

    Spickermann, Christian; Perlt, Eva; von Domaros, Michael; Roatsch, Martin; Friedrich, Joachim; Kirchner, Barbara


    Treating the bulk phase with high-level ab initio methods, such as coupled cluster, is a nontrivial task because of the computational costs of these electronic structure methods. In this part of our hydrogen fluoride study we make use of the quantum cluster equilibrium method, which employs electronic structure input of small clusters and combines it with simple statistical mechanics in order to describe condensed phase phenomena. If no parameter adjustment is applied, then the lower quantum chemical methods, such as density functional theory in conjunction with the generalized gradient approximation, provide wrong results in accordance with the description of the strength of the interaction in the clusters. While density functional theory describes the liquid phase too dense due to overbinding of the clusters, the coupled cluster method and the perturbation theory at the complete basis set limit agree well with experimental observations. If we allow the two parameters in the quantum cluster equilibrium method to vary, then these are able to compensate the overbinding, thereby leading to very good agreement with experiment. Correlated methods in combination with small basis sets giving rise to too weakly bound clusters cannot reach this accuracy even if the parameters are flexible. Only at the complete basis set limit, the performance of the correlated methods is again excellent.

  6. Monitoring pollution in River Mureş, Romania, part II: metal accumulation and histopathology in fish. (United States)

    Triebskorn, Rita; Telcean, Ilie; Casper, Heidi; Farkas, Anna; Sandu, Cristina; Stan, Gheorghe; Colărescu, Ovidiu; Dori, Tiberiu; Köhler, Heinz-R


    As a part of an exposure and effect monitoring conducted along the river Mureş, Western Romania in 2004, the health status of two indigenous fish species, sneep (Chondrostoma nasus) and European chub (Leuciscus cephalus) was investigated upstream and downstream the city of Arad. In fish, histopathology was assessed in liver and gills, and heavy metals (cadmium, copper, lead and zinc) were analyzed in liver samples. In both fish species, histopathological reactions in the gills (epithelial lifting, focal proliferation of epithelial cells of primary and secondary lamellae and resulting fusion of secondary lamellae, hyperplasia and hypertrophy of mucous cells, focal inflammation and necrosis of epithelial cells) were most severe at the two sampling sites upstream Arad city, which were shown to be polluted by copper, cadmium, faecal coliforms and streptococci in a parallel study. At these two sites, also histopathology in the liver of L. cephalus was more prominent than at the two downstream sites. In C. nasus, symptoms in the liver (focal inflammation with lymphocytic infiltrations, macrophage aggregates and single cell necrosis) were also highly pronounced at the sampling site located directly downstream the municipal sewage treatment plant of Arad. With the exception of copper accumulation in L. cephalus caught at the most upstream sampling site, in both fish species cadmium and copper accumulation were exceptionally high and did not differ significantly between the four sampling sites.

  7. Appropriateness and limitations of factor analysis methods utilized in psychology and kinesiology: Part II

    Directory of Open Access Journals (Sweden)

    Trninić Viktorija


    Full Text Available Structural modelling techniques and application of models that extract latent variables are recent predominant techniques in the applied multivariate statistical procedures in social sciences. We believe that correlation studies can provide adequate findings if they are supported by logical analysis or causal modelling procedures. It is important to emphasize that factor analysis methods alone do not reveal the cause of covariability and that the final result of factor analytical investigation depends, in part, on the decisions and interpretations of the researcher. The question of the minimum sample size in factor analysis, ambiguousness of results obtained by FA and mathematical problems in the use of FA is particularly scrupulously discussed in this paper. Furthermore, the effect of the factor analysis of data obtained from experiments on the scientific paradigm was analyzed, with emphasis on the current problems with its application in social sciences research. Neither method, including factor analysis, is sufficient to answer all problem issues in the field of psychology and kinesiology. Therefore, it is necessary to combine complementary methods within the research which will allow a more comprehensive analysis of the researched phenomena and a greater validity of empirical results. Finally, reducing theories in psychology to a psychometric method and theories in kinesiology to a kinesiometric method is an anomaly of numerous quantitative studies within these scientific disciplines, making identification, instead of explanation of multi-causal nature of psychological and kinesiological phenomena, a primary focus of the research.

  9. Topical immunomodulators for management of oral mucosal conditions, a systematic review; Part II: miscellaneous agents. (United States)

    Elad, Sharon; Epstein, Joel B; von Bültzingslöwen, Inger; Drucker, Scott; Tzach, Rinat; Yarom, Noam


    Topical immunomodulating preparations have utility in inflammatory/immune-mediated oral mucosal disease resistant to topical steroids, in immunologically mediated systemic disease with primary oral involvement or more severe lesions primarily involving the oral mucosa. This paper is the second part of a systematic review of a variety of topical immunomodulators for management of immune/inflammatory oral mucosal conditions. The literature search revealed studies of azathioprine, benzydamine, GM-CSF and G-CSF, tetracyclines, retinoids, imiquimod, amlexanox, sirolimus and bacillus Calmette-Guerin polysaccharide nucleic acid. Weighted conclusions are provided for the topical use of each of the immunomodulators reviewed in the management of these oral diseases. Topical immunomodulators may be useful as second line treatment in several oral diseases, particularly oral lichen planus and recurrent aphthous stomatitis. Benzydamine was found to be preventive in radiotherapy-induced mucositis; however, it is unclear if this outcome is related to its immunomodulating effects or other mechanisms of action. Topical application of tetracyclines and retinoic acid also shows potential anti-inflammatory actions.

    Full Text Available Background and Aim: Designing removable partial dentures is one of the most important phases of prosthetic treatments. Computer can be used to facilitate and increase accuracy of removable partial denture design. The aim of this study was to develop a software for removable partial denture design.Materials and Methods: A questionnaire (discussed in part I and major textbooks, were used to determine the design rules.  The software (RPD Graph was developed using Visual C++ and Maryam program.

  11. Tapped density optimisation for four agricultural wastes - Part II: Performance analysis and Taguchi-Pareto

    Directory of Open Access Journals (Sweden)

    Ajibade Oluwaseyi Ayodele


    Full Text Available In this attempt, which is a second part of discussions on tapped density optimisation for four agricultural wastes (particles of coconut, periwinkle, palm kernel and egg shells, performance analysis for comparative basis is made. This paper pioneers a study direction in which optimisation of process variables are pursued using Taguchi method integrated with the Pareto 80-20 rule. Negative percentage improvements resulted when the optimal tapped density was compared with the average tapped density. However, the performance analysis between optimal tapped density and the peak tapped density values yielded positive percentage improvements for the four filler particles. The performance analysis results validate the effectiveness of using the Taguchi method in improving the tapped density properties of the filler particles. The application of the Pareto 80-20 rule to the table of parameters and levels produced revised tables of parameters and levels which helped to identify the factor-levels position of each parameter that is economical to optimality. The Pareto 80-20 rule also produced revised S/N response tables which were used to know the relevant S/N ratios that are relevant to optimality.

  12. Scanning schemes in white light photoelasticity - Part II: Novel fringe resolution guided scanning scheme (United States)

    Ramakrishnan, Vivek; Ramesh, K.


    Varied spatial resolution of isochromatic fringes over the domain influences the accuracy of fringe order estimation using TFP/RGB photoelasticity. This has been brought out in the first part of the work. The existing scanning schemes do not take this into account, which leads to the propagation of noise from the low spatial resolution zones. In this paper, a method is proposed for creating a whole field map which represents the spatial resolution of the isochromatic fringe pattern. A novel scanning scheme is then proposed whose progression is guided by the spatial resolution of the fringes in the isochromatic image. The efficacy of the scanning scheme is demonstrated using three problems - an inclined crack under bi-axial loading, a thick ring subjected to internal pressure and a stress frozen specimen of an aerospace component. The proposed scheme has use in a range of applications. The scanning scheme is effective even if the model has random zones of noise which is demonstrated using a plate subjected to concentrated load. This aspect is well utilised to extract fringe data from thin slices cut from a stereo-lithographic model that has characteristic random noise due to layered manufacturing.

  13. Dermatologic conditions in skin of color: part II. Disorders occurring predominately in skin of color. (United States)

    Kundu, Roopal V; Patterson, Stavonnie


    Several skin conditions are more common in persons with skin of color, including dermatosis papulosa nigra, pseudofolliculitis barbae, acne keloidalis nuchae, and keloids. Dermatosis papulosa nigra is a common benign condition characterized by skin lesions that do not require treatment, although several options are available for removal to address cosmetic concerns. Pseudofolliculitis barbae occurs as a result of hair removal. Altering shaving techniques helps prevent lesions from recurring. In acne keloidalis nuchae, keloidal lesions are found on the occipital scalp and posterior neck. Early treatment with steroids, antibiotics, and retinoids prevents progression. A key part of the management of keloids is prevention. First-line medical therapy includes intralesional steroid injections. The distinct structure of the hair follicle in blacks results in hair care practices that can lead to common scalp disorders. For example, chemical relaxers decrease the strength of hair and may cause breakage. Better patient education, with early diagnosis and treatment, often leads to better outcomes. © 2013 American Academy of Family Physicians.

  14. Impact of caramelization on the glass transition temperature of several caramelized sugars. Part II: Mathematical modeling. (United States)

    Jiang, Bin; Liu, Yeting; Bhandari, Bhesh; Zhou, Weibiao


    Further to part I of this study, this paper discusses mathematical modeling of the relationship between caramelization of several sugars including fructose, glucose, and sucrose and their glass transition temperatures ( T g). Differential scanning calorimetry (DSC) was used for creating caramelized sugar samples and determining their glass transition temperatures ( T g). UV-vis absorbance measurement and high-performance liquid chromatography (HPLC) analysis were used for quantifying the extent of caramelization. Specifically, absorbances at 284 and 420 nm were obtained from UV-vis measurement, and the contents of sucrose, glucose, fructose, and 5-hydroxymethyl-furfural (HMF) in the caramelized sugars were obtained from HPLC measurements. Results from the UV and HPLC measurements were correlated with the Tg values measured by DSC. By using both linear and nonlinear regressions, two sets of mathematical models were developed for the prediction of Tg values of sugar caramels. The first set utilized information obtained from both UV-vis measurement and HPLC analysis, while the second set utilized only information from the UV-vis measurement, which is much easier to perform in practice. As a caramelization process is typically characterized by two stages, separate models were developed for each of the stages within a set. Furthermore, a third set of nonlinear equations were developed, serving as criteria to decide at which stage a caramelized sample is. The models were evaluated through a validation process.

  15. Ammonia emissions in Europe, part II: How ammonia emission abatement strategies affect secondary aerosols (United States)

    Backes, Anna M.; Aulinger, Armin; Bieser, Johannes; Matthias, Volker; Quante, Markus


    In central Europe, ammonium sulphate and ammonium nitrate make up a large fraction of fine particles which pose a threat to human health. Most studies on air pollution through particulate matter investigate the influence of emission reductions of sulphur- and nitrogen oxides on aerosol concentration. Here, we focus on the influence of ammonia (NH3) emissions. Emission scenarios have been created on the basis of the improved ammonia emission parameterization implemented in the SMOKE for Europe and CMAQ model systems described in part I of this study. This includes emissions based on future European legislation (the National Emission Ceilings) as well as a dynamic evaluation of the influence of different agricultural sectors (e.g. animal husbandry) on particle formation. The study compares the concentrations of NH3, NH4+, NO3 -, sulphur compounds and the total concentration of particles in winter and summer for a political-, technical- and behavioural scenario. It was found that a reduction of ammonia emissions by 50% lead to a 24% reduction of the total PM2.5 concentrations in northwest Europe. The observed reduction was mainly driven by reduced formation of ammonium nitrate. Moreover, emission reductions during winter had a larger impact than during the rest of the year. This leads to the conclusion that a reduction of the ammonia emissions from the agricultural sector related to animal husbandry could be more efficient than the reduction from other sectors due to its larger share in winter ammonia emissions.

  16. Compositional generative mapping for tree-structured data--part II: topographic projection model. (United States)

    Bacciu, D; Micheli, A; Sperduti, A


    We introduce GTM-SD (Generative Topographic Mapping for Structured Data), which is the first compositional generative model for topographic mapping of tree-structured data. GTM-SD exploits a scalable bottom-up hidden-tree Markov model that was introduced in Part I of this paper to achieve a recursive topographic mapping of hierarchical information. The proposed model allows efficient exploitation of contextual information from shared substructures by a recursive upward propagation on the tree structure which distributes substructure information across the topographic map. Compared to its noncompositional generative counterpart, GTM-SD is shown to allow the topographic mapping of the full sample tree, which includes a projection onto the lattice of all the distinct subtrees rooted in each of its nodes. Experimental results show that the continuous projection space generated by the smooth topographic mapping of GTM-SD yields a finer grained discrimination of the sample structures with respect to the state-of-the-art recursive neural network approach.

  17. A revision of the genus Muricea Lamouroux, 1821 (Anthozoa, Octocorallia) in the eastern Pacific. Part II (United States)

    Breedy, Odalisca; Guzman, Hector M.


    Abstract The species of the genus Muricea were mainly described from 1846 to 1870. After that very few contributions were published. Although the highest richness of Muricea species is in the eastern Pacific shallow waters, a comprehensive systematic study of the genus does not exist. Recently we started a taxonomic review of the genus in order to validate the status of four species previously included in the genus Eumuricea. Herein we present the second part of the Muricea revision dealing with the species-group characterised by shelf-like calyces instead of tubular-like calyces (the Muricea squarrosa-group). Original type material was morphologically analysed and illustrated using optical and scanning electron microscopy. Comparative character tables are provided for the genus. The taxonomic status of the species was analysed and established by designating lectotypes, alternatively by recognising a holotype by monotypy. We conclude that the genus Muricea comprises 20 valid species, including the previous four in the Muricea squarrosa-group. We propose 10 lectotypes, a new combination and three more species groups for the genus based on morphology: the Muricea fruticosa-group, Muricea plantaginea-group and Muricea austera-group.

  18. High temperature solid oxide fuel cell integrated with novel allothermal biomass gasification. Part II: Exergy analysis (United States)

    Panopoulos, K. D.; Fryda, L.; Karl, J.; Poulou, S.; Kakaras, E.

    Biomass gasification derived gas is a renewable fuel, which can be used for SOFC applications. This work investigates the integration of a near atmospheric solid oxide fuel cell (SOFC) with a novel allothermal biomass steam gasification process into a combined heat and power (CHP) system of less than MW e range. Heat for steam gasification is supplied from SOFC depleted fuel in a fluidised bed (FB) combustor via high temperature sodium heat pipes. In the first paper, the integrated system was modelled in Aspen Plus™ and critical aspects for its feasibility were identified. The aim of this second part is the evaluation of the integrated system in exergy terms. Satisfying allothermal gasification heat demand is illustrated by examining each sub-process involved separately as well as combined. For a relatively low STBR = 0.6, the SOFC fuel utilisation for which the system operates under optimum conditions is U f = 0.7. Above that value additional biomass has to be used in the FB combustor to provide gasification heat with considerable exergy losses. For SOFC operation at current density 2500 A m -2, the system uses 90 kg h -1 biomass, operates with electrical exergetic efficiency 32% producing 140 kW e, while the combined electrical and thermal exergetic efficiency is 35%.

  19. Determination of baghouse performance from coal and ash properties: part II

    Energy Technology Data Exchange (ETDEWEB)

    Vann Bush, P.; Snyder, T.R.; Chang, R.L.


    Baghouse performance at utility coal-fired power plants is determined by baghouse design, operating procedures, and the characteristics of the ash that is collected as a dustcake on the fabric filter. The Electric Power Research Institute has conducted laboratory research to identify the fundamental variables that influence baghouse performance. A database was assembled including measured characteristics of coal and dustcake ash, and data describing operating parameters and performance of full-scale and pilot-scale baghouses. Predictions of performance can be based on physical characteristics of the ash to be filtered (discussed in Part I of this article), as well as chemical characterizations of the ash, or empirical correlations with the alkali content of the source coal. The effects of design and operational variables can be included in these predictions. Baghouse performance can be optimized by exercising proper operating practices and by selecting a filtering fabric and cleaning method matched to the cohesivity of the ash to be collected. 13 refs., 13 figs., 2 tabs.

  20. Process analysis transit of municipal waste. Part II - Domestic provisions of law

    Directory of Open Access Journals (Sweden)

    Starkowski Dariusz


    Full Text Available In 2013, the Polish legal system referring to municipal waste management was restructured in a revolutionary way. The analysis of new provisions of law described in the article requires particular attention, taking into account their place in the entire system of dealing with waste and connections with the remaining elements of this system. At present, Polish regulations lay down the rules of conduct with all types of waste, diversifying a subjective area of responsibility. These assumptions are determined by the provisions of law that are in force in the Republic of Poland. At present, the system of legal provisions is quite complex; however, the provisions of law of the EU constitute its base (the first article. At the level of Polish law, the goals and tasks concerned with dealing with waste were set forth, which leads to tightening of the system. All actions in this respect - from propagating the selective accumulation and collection of municipal waste, keeping the established levels of recycling and recycling of packaging wastes, and limiting the mass of biodegradable waste directed at the storage - is only a beginning of the road to reduction of environmental risks. In this case, permanent monitoring of proper waste dealing in the commune, the province as well as the entire country is essential. Third part of the article will present characterization, division, classification and identification of waste, together with the aspects of logistic process of municipal waste collection and transport.

  1. Involvement of l(-)-rhamnose in sea urchin gastrulation. Part II: α-l-Rhamnosidase. (United States)

    Liang, Jing; Aleksanyan, Heghush; Metzenberg, Stan; Oppenheimer, Steven B


    The sea urchin embryo is recognized as a model system to reveal developmental mechanisms involved in human health and disease. In Part I of this series, six carbohydrates were tested for their effects on gastrulation in embryos of the sea urchin Lytechinus pictus. Only l-rhamnose caused dramatic increases in the numbers of unattached archenterons and exogastrulated archenterons in living, swimming embryos. It was found that at 30 h post-fertilization the l-rhamnose had an unusual inverse dose-dependent effect, with low concentrations (1-3 mM) interfering with development and higher concentrations (30 mM) having little to no effect on normal development. In this study, embryos were examined for inhibition of archenteron development after treatment with α-l-rhamnosidase, an endoglycosidase that removes terminal l-rhamnose sugars from glycans. It was observed that the enzyme had profound effects on gastrulation, an effect that could be suppressed by addition of l-rhamnose as a competitive inhibitor. The involvement of l-rhamnose-containing glycans in sea urchin gastrulation was unexpected, since there are no characterized biosynthetic pathways for rhamnose utilization in animals. It is possible there exists a novel l-rhamnose-containing glycan in sea urchins, or that the enzyme and sugar interfere with the function of rhamnose-binding lectins, which are components of the innate immune system in many vertebrate and invertebrate species.

  3. Early severe acute respiratory distress syndrome: What's going on? Part II: controlled vs. spontaneous ventilation? (United States)

    Petitjeans, Fabrice; Pichot, Cyrille; Ghignone, Marco; Quintin, Luc


    The second part of this overview on early severe ARDS delineates the pros and cons of the following: a) controlled mechanical ventilation (CMV: lowered oxygen consumption and perfect patient-to-ventilator synchrony), to be used during acute cardio-ventilatory distress in order to "buy time" and correct circulatory insufficiency and metabolic defects (acidosis, etc.); b) spontaneous ventilation (SV: improved venous return, lowered intrathoracic pressure, absence of muscle atrophy). Given a stabilized early severe ARDS, as soon as the overall clinical situation improves, spontaneous ventilation will be used with the following stringent conditionalities: upfront circulatory optimization, upright positioning, lowered VO2, lowered acidotic and hypercapnic drives, sedation without ventilatory depression and without lowered muscular tone, as well as high PEEP (titrated on transpulmonary pressure, or as a second best: "trial"-PEEP) with spontaneous ventilation + pressure support (or newer modes of ventilation). As these propositions require evidence-based demonstration, the reader is reminded that the accepted practice remains, in 2016, controlled mechanical ventilation, muscle relaxation and prone position.

  4. ARFI ultrasound for in vivo hemostasis assessment postcardiac catheterization, part II: pilot clinical results. (United States)

    Behler, Russell H; Scola, Mallory R; Nichols, Timothy C; Caughey, Melissa C; Fisher, Melrose W; Zhu, Hongtu; Gallippi, Caterina M


    In this second of a two part series, we present pilot clinical data demonstrating Acoustic Radiation Force Impulse (ARFI) ultrasound for monitoring the onset of subcutaneous hemostasis at femoral artery puncture sites (arteriotomies), in vivo. We conducted a randomized, reader-blinded investigation of 20 patient volunteers who underwent diagnostic percutaneous coronary catheterization. After sheath removal (6 French), patients were randomized to treatment with either standard of care manual compression alone or, to expedite hemostasis, manual compression augmented with a p-GlcNAc fiber-based hemostatic dressing (Marine Polymer Technologies, Danvers MA). Concurrent with manual compression, serial ARFI imaging began at the time of sheath removal and continued every minute for 15 min. Serial data sets were processed with custom software to (1) estimate the time of hemostasis onset, and (2) render hybrid ARFI/B-Mode images to highlight displacements considered to correspond to extravasted blood. Images were read by an observer blinded to the treatment groups. Average estimated times to hemostasis in patient volunteers treated with manual compression alone (n = 10) and manual compression augmented by hemostatic dressing (n = 9) were, respectively, 13.00 +/- 1.56 and 9.44 +/- 3.09 min, which are statistically significantly different (p = 0.0065, Wilcoxon two-sample test). Example images are shown for three selected patient volunteers. These pilot data suggest that ARFI ultrasound is relevant to monitoring subcutaneous bleeding from femoral arteriotomies clinically and that time to hemostasis was significantly reduced by use of the hemostatic dressing.

  6. An Ansatz Regarding Relativistic Space Travel Part II-Propulsion Realities (United States)

    Murad, Paul A.


    Travel to the stars can involve a perilous journey in an unfriendly space-time continuum that can include singularities, nonlinear events, gravity as a function of both position and vehicle velocity, and extra dimensional effects discussed in Part I. Such a device may possibly use field propulsion technology. Although several field propulsion schemes exist, a proposed candidate is based upon using an electromagnetic drive that uses a rotating magnetic field superimposed on the spacecraft's stationary or static electric field. This is comparable to a Searl generator and the field interaction would generate an electromagnetic vortex to create nonlinear gravitational effects possibly due to an inverse Gertsenshtein relationship to push against the intrinsic gravitational field of a planet. Moreover, changing alignment of the magnetic field axis with the electric field will induce a margin of lateral controllability. Issues such as assessing this combined effect of using both electric and magnetic fields are discussed. Finally, the need for experimental data is stressed to validate these otherwise very speculative theoretical notions.

  7. Part I. Student success in intensive versus traditional introductory chemistry courses. Part II. Synthesis of salts of the weakly coordinating trisphat anion (United States)

    Hall, Mildred V.

    Part I. Intensive courses have been shown to be associated with equal or greater student success than traditional-length courses in a wide variety of disciplines and education levels. Student records from intensive and traditional-length introductory general chemistry courses were analyzed to determine the effects, of the course format, the level of academic experience, life experience (age), GPA, academic major and gender on student success in the course. Pretest scores, GPA and ACT composite scores were used as measures of academic ability and prior knowledge; t-tests comparing the means of these variables were used to establish that the populations were comparable prior to the course. Final exam scores, total course points and pretest-posttest differences were used as measures of student success; t-tests were used to determine if differences existed between the populations. ANCOVA analyses revealed that student GPA, pretest scores and course format were the only variables tested that were significant in accounting for the variance of the academic success measures. In general, the results indicate that students achieved greater academic success in the intensive-format course, regardless of the level of academic experience, life experience, academic major or gender. Part II. Weakly coordinating anions have many important applications, one of which is to function as co-catalysts in the polymerization of olefins by zirconocene. The structure of tris(tetrachlorobenzenedialato) phosphate(V) or "trisphat" anion suggests that it might be an outstanding example of a weakly coordinating anion. Trisphat acid was synthesized and immediately used to prepare the stable tributylammonium trisphat, which was further reacted to produce trisphat salts of Group I metal cations in high yields. Results of the 35Cl NQR analysis of these trisphat salts indicate only very weak coordination between the metal cations and the chlorine atoms of the trisphat anion.

  8. Blurring the boundaries: using institutional ethnography to inquire into health professions education and practice. (United States)

    Ng, Stella L; Bisaillon, Laura; Webster, Fiona


    Qualitative, social science approaches to research have surged in popularity within health professions education (HPE) over the past decade. Institutional ethnography (IE) offers the field another sociological approach to inquiry. Although widely used in nursing and health care research, IE remains relatively uncommon in the HPE research community. This article provides a brief introduction to IE and suggests why HPE researchers may wish to consider it for future studies. Part 1 of this paper presents IE's conceptual grounding in: (i) the entry point to inquiry ('materiality'), (ii) a generous definition of 'work' and (iii) a focus on how 'texts' such as policies, forms and written protocols influence activity. Part 2 of this paper outlines the method's key features through exemplars from our own research. Part 3 discusses the ways in which research that blurs the lines between educational and clinical practice can be both generative for HPE and accomplished using IE. The authors demonstrate the usefulness of IE for studying complex social issues in HPE. It is posited that a key added value of IE is that it goes beyond individual-level explanations of problems and phenomena, yet also closely studies individuals' activities, rather than remaining at an abstract or distant level of analysis. Thereby, IE can result in feasible and meaningful social change at the nexus of health professions education and other social systems such as clinical practice. IE adds to the growing qualitative research toolkit for HPE researchers. It is worth considering because it may enable change through the study of HPE in relation to other social processes, structures and systems, including the clinical practice world. A particular benefit may be found in blending HPE research with research on clinical practice, toward changing practice and policy through IE, given the interrelated nature of these fields. © 2016 John Wiley & Sons Ltd and The Association for the Study of Medical Education.

    Purpose: Dual-energy (DE) contrast-enhanced digital mammography (CEDM) uses an iodinated contrast agent in combination with digital mammography (DM) to evaluate lesions on the basis of tumor angiogenesis. In DE imaging, low-energy (LE) and high-energy (HE) images are acquired after contrast administration and their logarithms are subtracted to cancel the appearance of normal breast tissue. Often there is incomplete signal cancellation in the subtracted images, creating a background “clutter” that can impair lesion detection. This is the second component of a two-part report on anatomical noise in CEDM. In Part I the authors characterized the anatomical noise for single-energy (SE) temporal subtraction CEDM by a power law, with model parameters α and β. In this work the authors quantify the anatomical noise in DE CEDM clinical images and compare this with the noise in SE CEDM. The influence on the anatomical noise of the presence of iodine in the breast, the timing of imaging postcontrast administration, and the x-ray energy used for acquisition are each evaluated.Methods: The power law parameters, α and β, were measured from unprocessed LE and HE images and from DE subtracted images to quantify the anatomical noise. A total of 98 DE CEDM cases acquired in a previous clinical pilot study were assessed. Conventional DM images from 75 of the women were evaluated for comparison with DE CEDM. The influence of the imaging technique on anatomical noise was determined from an analysis of differences between the power law parameters as measured in DM, LE, HE, and DE subtracted images for each subject.Results: In DE CEDM, weighted image subtraction lowers β to about 1.1 from 3.2 and 3.1 in LE and HE unprocessed images, respectively. The presence of iodine has a small but significant effect in LE images, reducing β by about 0.07 compared to DM, with α unchanged. Increasing the x-ray energy, from that typical in DM to a HE beam, significantly decreases α by about 2

  16. The wind and thermally driven circulation of the eastern Mediterranean Sea. Part II: the Baroclinic case (United States)

    Malanotte-Rizzoli, Paola; Bergamasco, Andrea


    Compared with other interesting parts of the World Ocean, little is known of the eastern Mediterranean and major issues of the Mediterranean circulation are still unsolved. Among them, the most crucial one is: what is the dominant driving mechanism of the eastern Mediterranean general circulation: (1) the wind stress; (2) the thermohaline surface fluxes; (3) the inflow forcing at the Sicily Straits? What is the relative importance of these three forcing functions? Is it the same in the different sub-basins comprising the eastern Mediterranean? What modelling factors are important for the simulation of the seasonal cycle and is the general circulation overall dominated by the annual mean or seasonal signal? To answer the above questions we have carried out an extensive and thorough series of numerical experiments using a multilevel model of the circulation, suitable for coarse-resolution studies but endowed with active thermodynamics and allowing for realistic geometry (coastlines, islands, bottom relief). The model is used in a three-level version as the minimum one capable of simulating the vertical superposition of different water masses observed in the eastern Mediterranean. The climatological monthly averages of wind-stress, thermal and evaporative fluxes and inflow at Sicily are used to drive the model. In Part I of the present study it was shown that the seasonal cycle present in the wind-stress curl induces a strongly seasonal barotropic circulation comprising the entire eastern Mediterranean. This seasonal gyre reverses from being cyclonic in winter to anticyclonic in summer. The inclusion of baroclinicity, however, profoundly modifies the purely wind-driven, barotropic circulation, eliminating the strong seasonality and the winter-to-summer reversal. The first important result is that the general circulation pattern now consists of a succession of sub-basin-scale gyres, with a seasonal modulation emphasizing the cyclonic centres in winter and the

    Physical training for United States military personnel requires a combination of injury prevention and performance optimization to counter unintentional musculoskeletal injuries and maximize warrior capabilities. Determining the most effective activities and tasks to meet these goals requires a systematic, research-based approach that is population specific based on the tasks and demands of the Warrior. The authors have modified the traditional approach to injury prevention to implement a comprehensive injury prevention and performance optimization research program with the 101st Airborne Division (Air Assault) at Fort Campbell, KY. This is second of two companion papers and presents the last three steps of the research model and includes Design and Validation of the Interventions, Program Integration and Implementation, and Monitor and Determine the Effectiveness of the Program. An 8-week trial was performed to validate the Eagle Tactical Athlete Program (ETAP) to improve modifiable suboptimal characteristics identified in Part I. The experimental group participated in ETAP under the direction of a ETAP Strength and Conditioning Specialist while the control group performed the current physical training at Fort Campbell under the direction of a Physical Training Leader and as governed by FM 21-20 for the 8-week study period. Soldiers performing ETAP demonstrated improvements in several tests for strength, flexibility, performance, physiology, and the APFT compared to current physical training performed at Fort Campbell. ETAP was proven valid to improve certain suboptimal characteristics within the 8-week trial as compared to the current training performed at Fort Campbell. ETAP has long-term implications and with expected greater improvements when implemented into a Division pre-deployment cycle of 10-12 months which will result in further systemic adaptations for each variable.

    Full Text Available Abstract Introduction In the last 28 years, the scientific community has been using elastography to evaluate the mechanical properties of biological tissue. The aim of this work was the optimization of the UDmV method, presented in Part I of the series, by means of modifying the technique employed to generate the reference sine and cosine functions, used for phase-quadrature demodulation, and determining how this modification improved the performance of the method. Additionally, the UDmV was employed to characterize the acoustic and mechanical properties of a 7% gelatin phantom. Methods A focused transducer, T F, with a nominal frequency of 2.25 MHz, was used to induce the shear waves, with frequency of 97.644 Hz. Then, the modified UDmV method was used to extract the phase and quadrature components from ultrasonic RF echo-signals collected from four positions along the propagation path of the shear wave, which allowed the investigation of the medium vibration caused by wave propagation. The phase velocity, c s, and attenuation, α s, of the phantom were measured and employed in the calculation of shear modulus, μ, and viscosity, η. Results The computational simulation demonstrated that the modification in UDmV method resulted in more accurate and precise estimates of the initial phases of the reference sinusoidal functions used for phase-quadrature demodulation. The values for c s and μ of 1.31 ± 0.01 m·s-1 and 1.66 ± 0.01 kPa, respectively, are very close to the values found in the literature (1.32 m·s-1 and 1.61 kPa for the same material. Conclusion The UDmV method allowed estimating of the acoustic and viscoelastic parameters of phantom.

  19. Weighed scalar averaging in LTB dust models: part II. A formalism of exact perturbations (United States)

    Sussman, Roberto A.


    We examine the exact perturbations that arise from the q-average formalism that was applied in the preceding article (part I) to Lemaître-Tolman-Bondi (LTB) models. By introducing an initial value parametrization, we show that all LTB scalars that take an FLRW ‘look-alike’ form (frequently used in the literature dealing with LTB models) follow as q-averages of covariant scalars that are common to FLRW models. These q-scalars determine for every averaging domain a unique FLRW background state through Darmois matching conditions at the domain boundary, though the definition of this background does not require an actual matching with an FLRW region (Swiss cheese-type models). Local perturbations describe the deviation from the FLRW background state through the local gradients of covariant scalars at the boundary of every comoving domain, while non-local perturbations do so in terms of the intuitive notion of a ‘contrast’ of local scalars with respect to FLRW reference values that emerge from q-averages assigned to the whole domain or the whole time slice in the asymptotic limit. We derive fluid flow evolution equations that completely determine the dynamics of the models in terms of the q-scalars and both types of perturbations. A rigorous formalism of exact spherical nonlinear perturbations is defined over the FLRW background state associated with the q-scalars, recovering the standard results of linear perturbation theory in the appropriate limit. We examine the notion of the amplitude and illustrate the differences between local and non-local perturbations by qualitative diagrams and through an example of a cosmic density void that follows from the numeric solution of the evolution equations.
