  2. On Einstein's Doctoral Thesis

    CERN Document Server

    Straumann, N


    Einstein's thesis ``A New Determination of Molecular Dimensions'' was the second of his five celebrated papers in 1905. Although it is -- thanks to its widespread practical applications -- the most quoted of his papers, it is less known than the other four. The main aim of the talk is to show what exactly Einstein did in his dissertation. As an important application of the theoretical results for the viscosity and diffusion of solutions, he got (after eliminating a calculational error) an excellent value for the Avogadro number from data for sugar dissolved in water. This was in agreement with the value he and Planck had obtained from the black-body radiation. Two weeks after he finished the `Doktorarbeit', Einstein submitted his paper on Brownian motion, in which the diffusion formula of his thesis plays a crucial role.

  4. Lessons from a doctoral thesis. (United States)

    Peiris, A N; Mueller, R A; Sheridan, D P


    The production of a doctoral thesis is a time-consuming affair that until recently was done in conjunction with professional publishing services. Advances in computer technology have made many sophisticated desktop publishing techniques available to the microcomputer user. We describe the computer method used, the problems encountered, and the solutions improvised in the production of a doctoral thesis by computer. The Apple Macintosh was selected for its ease of use and intrinsic graphics capabilities. A scanner was used to incorporate text from published papers into a word processing program. The body of the text was updated and supplemented with new sections. Scanned graphics from the published papers were less suitable for publication, and the original data were replotted and modified with a graphics-drawing program. Graphics were imported and incorporated in the text. Final hard copy was produced by a laser printer and bound with both conventional and rapid new binding techniques. Microcomputer-based desktop processing methods provide a rapid and cost-effective means of communicating the written word. We anticipate that this evolving technology will have increased use by physicians in both the private and academic sectors. PMID:2308505

  5. Towards a doctoral thesis through published works. (United States)

    Breimer, L H; Mikhailidis, D P


    Doctoral theses submitted in medical schools under a system dependent on publications (Sweden) and one which was not (UK) were compared. A subset consisting of UK theses containing papers (about 1/3 of all UK theses) was used. The publication-based theses gave candidates a significantly higher (P < 0.03) profile in terms of key authorship positions. Nevertheless, in 66% of the UK theses with papers the candidate was either the first or sole author. Swedish and UK theses with papers were of equal quality when assessed by the number of papers in journals: a) ranked in the top 100 (14% vs 10%) or 200 (26% vs 32%); or b) used more than once and either ranked in the top 1000 (median 224 vs 218) or in the top two thirds by subject section (98 vs 100%). UK theses benefitted from the greater impact of journals emanating from the UK compared to continental Europe (P < 0.001). An estimated 13% of UK PhD theses overall included three or more papers per thesis despite no requirement of publication. A publication-based doctorate should be introduced on trial in parallel with the existing systems to ensure efficiency and international comparability. PMID:8068863

  11. Process development of thermal hydrodechlorination. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    ten Kate, A.J.B.


    The properties that make chlorinated compounds so attractive during their economic lifetime are closely related to, if not similar to, the properties causing the environmental problems. A very promising method for proper chlorinated waste treatment is thermal hydrodechlorination. This process turns chlorinated waste into HC1, that might be recycled, and into organics which can be used as a fuel. The objective of the study underlying this thesis is scaling up thermal hydrodechlorination to a waste destruction process at industrial scale. To get answers to the unknown two installations have been raised: a mini pilot plant, and a bench scale installation.

  12. Near-surface seismic imaging. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Scheffers, B.C.


    Processing of seismic data requires more and more sophisticated techniques as hydrocarbon plays get smaller and smaller. Depth migration, for example, depends on accurate velocity models of the subsurface to obtain correctly imaged depth sections or depth cubes of small hydrocarbon reservoirs. Much research is carried out on new techniques for the estimation of such macro velocity models. Currently, research is concentrated in two directions: techniques for estimating the velocity of the weather layer (the ultra shallow zone), and techniques for estimating the macro model of the total overburden (of the deep zone). The objective of this thesis is to present an improved and cost-effective data acquistion and inversion technique that provides a velocity macro model of ultra shallow and the shallow zone, using an algorithm that incorporates all available information.

  15. Ionizing radiation induced transcriptional changes in the developing mouse brain. Doctoral Thesis Prepared at SCK-CEN and Defended in 2006

    International Nuclear Information System (INIS)

    Brain damage induced by prenatal irradiation is of major concern in radioprotection. The brain is the final result of a series of well timed consecutive waves of cellular proliferation, migration, and differentiation. Acute irradiation during pregnancy could selectively disturb these events to result in various forms of malformations such as microencephaly, reduced cortical thickness, glioblastoma tumours and/or mental retardation. In this work we concentrated on the transcriptional alterations induced by ionising radiation in the mouse developing brain and its different cell-types. Using cDNA-microarrays and real-time PCR, we analysed the modulated gene expression profile after 50 cGy X-ray exposure in embryonic mouse total brains at three developmental stages. Functional grouping of the modulated mRNA transcripts revealed that the main activated pathways in irradiated wild type embryos are involved in the induction of Trp53 dependent programmed cell death and intracellular signalling cascades. The strong upregulation of Ccng1, Trp53inp1 and Cdkn1a suggested that the tumour suppressor P53 protein is an essential regulator of the radiation induced stress response. Moreover, a decreasing expression profile could be identified at later development, suggesting a reducing sensitivity to radiation. The information obtained lead to a subsequent experiment in which the ionising radiation response in P53 deficient embryonic brains at the same developmental stages was determined. Since both genotypes showed the strongest gene expression modulation at developmental stage E13, we concentrated our initial analysis on this developmental stage. In one hand, wild type embryos show a strong upregulation for Trp53inp1 and Ccng1 in the irradiated E13 mouse brain was observed. Considering the fact that they are involved in similar functions, and that Trp53inp1 is less strongly induced then Ccng1, let us suggest that P53 is tightly regulated through different mechanisms after

  17. [The effect of public defense of a doctoral thesis on the heart rate of the doctoral candidate]. (United States)

    Kiljander, Toni; Toikka, Jyri; Koskenvuo, Juha; Jaakkola, Ilkka


    The effect of public defense of a doctoral thesis on the heart rate of the doctoral candidate Most doctoral candidates find the public defense of a doctoral thesis an exciting and stressful experience. In this study, Holter recording during the defense was made for four doctoral candidates of the Faculty of Medicine. Maximum heart rate among the subjects was on the average 172 beats/min with a median heart rate of 116 beats/min. Sympathicotonia and release of stress hormones associated with the defense raise the heart rate to levels that may be very high for several hours. This is a risk factor for a coronary event and should be considered, if the doctoral candidate has coronary heart disease, carries risk factors for coronary heart disease, or is an elderly person.

  4. Surface spectroscopic studies of high-temperature superconductors. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Rietveld, G.


    In this thesis the results are described of an experimental study in which surface spectroscopic techniques are used to examine the electronic structure of the high-Tc superconductors. Apart from the work presented here, the project also contained growth and analysis of thin films, and development of devices. The in situ preparation of high-quality thin films was essential for performing useful measurements of the surface properties of the high-Tc materials. The aim of the present study is to contribute to the understanding of the character of the superconducting phase transition and of the electronic structure of these materials. The main thread that connects all chapters is the behavior of the chemical potential, which--as the authors shows--can give useful information with respect to these points.

  5. Modeling processes in the design of electricity tariffs. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Raesaenen, M.


    This thesis considers the modeling process for analyzing consumers` responses to innovative electricity tariffs. Specifically, it focuses on estimating the rate effects from demand data, modeling the demand behavior and utilizing them in the design of optional rates. The econometric analysis is based on the dynamic pricing experiments which were conducted in Finland from 1988 to 1993. The results indicate that customer level load analysis is required, since the effects of rate changes on the consumption can vary considerably from customer to customer. When the analysis is conducted with respect to individual customers, those customers with high price response potential can be identified and their responsiveness can be efficiently utilized in rate design. The load analysis techniques are implemented in an object-oriented load modeling environment.

  7. Electrochemical vapour deposition of SOFC interconnection materials. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    van Dieten, V.


    The aim of this thesis is to investigate the synthesis of the SOFC (Solid Oxide Fuel Cells) interconnection material Mg-doped LaCrO3 by means of EVD (electrochemical vapor deposition). Although the EVD process is the key technology for the fabrication of the interconnect of the Westinghouse tubular concept SOFC, very little has been published on this subject. Nearly all publications on EVD are dealing with the synthesis of the electrolyte material YSZ. In Chapter 2 the principle of the EVD process is described, as well as the experimental setups used for the synthesis experiments. In Chapter 3 a thermodynamic analysis of the La-Cr-Mg-O-H-Cl-Ar system is made in order to determine how the EVD process conditions may affect the incorporation of magnesium in LaCrO3, and to predict the range of experimental conditions for the synthesis of Mg-doped LaCrO3 by means of CVD (chemical vapor deposition)/EVD. In Chapter 4 the EVD stage of the growth process is modeled. The experimental results of the synthesis of Mg-doped LaCrO3 on porous and gastight substrates are described in Chapter 5. In Chapter 6 the first results on the synthesis of the perovskite oxide YCrO3, a material resembling LaCrO3, by means of particle-precipitation-aided CVD(PP-CVD) are described, as well as the principles of the process.

  8. Land surface heterogeneity in 3-dimensional atmospheric simulations. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Seth, A.


    Stand-alone, vectorized version of the Biosphere-Atmosphere Transfer Scheme (VBATS) and a regional climate model (ReGCM2) are used to study the effects of subgrid scale heterogeneity in land surface processes on large scale mean surface fluxes and on mesoscale dynamics, respectively. The thesis is about the interactions of large and small scales within the climate system. We are concerned with two climate subsystems; the land surface and the atmosphere. We shall define large scales as those which can be resolved by current atmospheric general circulation models (grid resolutions of 100-200 km can resolve wavelengths of 400-800 km and larger). Small scales, or subgrid scale processes, are those which cannot be resolved by the resolution of global scale atmospheric models, but may be resolved using models with limited area domains. Our discussion will focus on the physical interactions between land and atmosphere and, specifically, will explore the effects of surface heterogeneity. Chemical exchanges are not considered here, nor is the evolution of the biosphere.

  9. Acoustic and optical investigations of superfluid 3He. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Manninen, A.


    The thesis is an experimental survey of properties of rotating and stationary superfluid (3)He. Two techniques, acoustics and optics, were used. Ultrasound, together with NMR, has provided most of the present experimental knowledge about the superfluid phases of (3)He. The author applied acoustics for the first time to study rotating (3)He. The main result was the discovery of a new vortex in (3)He-A when the magnetic field is low. New phenomena were observed in stationary (3)He as well. Most importantly, one of the collective modes, the real squashing (rsq) mode, of (3)He-B could be excited by means of two-phonon absorption. Superfluid (3)He was studied optically for the first time. No one has previously seen (3)He in the superfluid state. The principal achievement was developing techniques which facilitate optical experiments at temperatures below 1 mK, required to study superfluid (3)He. Optical fibers were used to transmit light between room temperature and the cold parts of the cryostat. Before these investigations, photography had not been done below 10 mK. The usefulness of optics as a proble of the superfluid phases of (3)He was demonstrated by studying the macroscopic shape of the free surface of rotating (3)He-B. The classical parabolic meniscus was observed, which is indicative of the equilibrium density of vortices.

  10. Marine microbial production of dimethylsulfide from dissolved dimethylsulfoniopropionate. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Ledyard, K.M.


    Dimethylsulfide (DMS) plays a central role in the transfer of sulfur from the ocean to the atmosphere, and ultimately to land. The most abundant volatile organosulfur compound in seawater, DMS is believed to account for the bulk of the sea-to-air biogenic sulfur flux. DMS has also been implicated as the major precursor of submicron-sized sulfate aerosol over the ocean. This aerosol acts as an effective site for cloud droplet condensation, suggesting a possibly important role for DMS in marine cloud formation. In the ocean, the precursor of DMS is presumed to be the zwitterionic sulfonium compound dimethylsulfoniopropionate (DMSP), a common osmoticum in certain classes of marine algae. While some algae can cleave DMSP intracellularly to form DMS, correlation of DMS concentrations with indicators of algal productivity on a local scale is poor. This thesis focuses on an alternative pathway of DMS formation: microbial cleavage of dissolved (extracellular) DMSP. In laboratory studies, bacteria able to cleave DMSP to form DMS were isolated from seawater by a DMSP enrichment technique, and the kinetics of DMSP uptake and DMS production were examined closely in pure cultures of a bacterial isolate from the Sargasso Sea. The isolate could grow with both DMSP and acrylic acid, one of the products of DMSP cleavage, as the sole source of carbon and energy, and the enzyme catalyzing DMSP cleavage appeared to be induced by both of these compounds. Kinetic parameters were estimated for DMSP uptake and cleavage by whole cells. Comparison of the 16S rRNA sequence of this isolate with that of known eubacteria showed that it was most closely related to Erythrobacter longus, an aerobic, bacteriochlorophyll-containing member of the alpha proteobacteria.

  13. A Juggling Act: Supervisor/Candidate Partnership in a Doctoral Thesis by Publication

    Directory of Open Access Journals (Sweden)

    rohan nethsinghe


    Full Text Available Increasingly doctoral candidates are attempting to complete a thesis by publication. This format varies between universities but there are common issues particularly in terms of progression, planning and timing. There are both advantages and difficulties involved in undertaking a thesis in this format. Our discussion of the supervisor/candidate partnership is framed within the requirements of a tight journal publishing agenda. Different universities have different requirements about the number of published papers to be included, the extent of candidate’s contribution as sole or joint author, the framing of the research as a unified thesis, presentation, and examination. The decision to attempt a thesis by publication must be taken early and data collection may need to be completed early. Articles then need to be written, polished, submitted, reviewed, revised and, hopefully, accepted. The thesis by publication is a juggling act between maintaining coherence and focusing on publishable segments. It is also a dialogue between supervisor and candidate involving the resolution of sometimes conflicting demands. Employing Cognitive Apprenticeship theory we present a shared autophenomenography that chronicles our doctoral journey that led to a successful thesis by publication. The findings are discussed under thematic headings: Logistics, Cognitive Apprenticeship in Action, and Building Trust.

    Paillassard, Pierrette; Schöpfel, Joachim; Stock, Christiane


    In 1985 the French government created a unique circuit for the dissemination of doctoral theses: References went to a national database “Téléthèses” whereas the documents were distributed to the university libraries in microform. In the era of the electronic document this French network of deposit of and access to doctoral theses is changing. How do you discover and locate a French thesis today, how do you get hold of a paper copy and how do you access the full electronic text? What are the c...

  15. Thesis-Building: Architecture, Alchemy and the Constructive Moment(s of a Doctoral Dissertation

    Directory of Open Access Journals (Sweden)

    Willem de Bruijn


    Full Text Available This paper looks back at the long and sometimes difficult process of doing a ‘PhD’. It asks how certain ‘moments’ in the building of a doctoral thesis – moments of conception, of discovery, of despair, of truth, of revelation and of jouissance – inform the building of a thesis. By revisiting these moments, the paper traces the genesis of the author’s thesis on Architecture and Alchemy and explores the metaphor of construction encountered in the work of cultural theorist Walter Benjamin.Drawing on some of the historical sources of the thesis, in particular the emblem books of seventeenth-century alchemist Michael Maier (1568-1622, the paper argues that the above-named ‘moments’ in a PhD constitute an ensemble of impassioned investment, which can be known as the PhD-pathos. This paper, then, can be read as no more, or less, than a pathological guide to the PhD, where architecture and alchemy come into play as polar opposites in the process of construction and change that thesis-building is.

  16. [Doctoral thesis: Demographic growth and economic and social development in Mali]. (United States)

    Dabo, K


    A doctoral thesis is described analyzing the relationships between demographic growth and economic and social development in Mali. The hypothesis is stated that demographic growth impedes economic development and any improvement in populations¿ standards of living. The hypothesis was verified using data for the period from 1960 to the present. Over that period, Mali conducted two general population censuses in 1976 and 1987, as well as several demographic research studies. The thesis is comprised of 4 parts, of which the first generally describes Mali. The second part analyzes the relationship between population growth and economic and social development in Mali. Study results are presented, followed by an analysis of the effects of economic and social development upon population growth in Mali through factors such as urbanization, education level, literacy, income, employment, occupation, gross domestic or gross national product by inhabitant, infant mortality rate, life expectancy at birth, contraceptive practice, fertility opinions and desires, women¿s status, and migration in Mali. Analysis indicates that Mali has not completely begun its demographic transition, but that traditional pronatalist behaviors are changing. Population policies and programs are explored in the third part of the thesis, followed by the fourth part which focuses upon methodological questions. PMID:12296197

  17. A doctoral thesis about Carol Davila written in Paris in 1936. (United States)

    Rogozea, Liliana; Dumitrascu, Dinu I; Triff, Dorin; Leasu, Florin; Dumitraşcu, Dan L


    Carol Davila, the father of the Romanian modern medicine, made decisive contributions to the development of health sciences in the Romanian Principalities in the last decades of the nineteenth century. The merit of his scientific work was recognized beyond the borders of his country. His life (not devoid of anecdotic instances and unknown episodes) and especially his work have aroused considerable interest among numerous medical historians. This paper presents a historical study elaborated in France, but until recently ignored, dedicated to the biography of Carol Davila. It concerns the medical doctoral thesis (State Diploma) elaborated by Joseph Adler (born 1910 in Botoşani, Romania) under the supervision of professor Maxime Laignel-Lavastine, whose interest in Romania is well-known. Professor Laignel-Lavastine held the office of Secretary General of the International Society of History of Medicine (ISHM), founded in 1921, (replaced in this position by another French professor with links to Romania: Jules Guiart). The thesis comprises 48 pages and an exhaustive bibliography. It represents a token of the appreciation given to Davila's achievements by Europe's medical community. PMID:26527997

  18. Finding the right doctoral thesis – an innovative research fair for medical students

    Directory of Open Access Journals (Sweden)

    Steffen, Julius


    Full Text Available Introduction: The importance of research, as promoted by the framework, is widely acknowledged. Many medical students in Germany work on a research project as part of their doctoral thesis whilst still going to medical school. However, a significant amount of projects are abandoned unfinished, which leads to substantial wastage of resources. One reason for this is an information deficit concerning undergraduate research projects.Project description: To counteract this, we introduced an annual event at LMU Munich called with more than 600 visitors each year.

  19. Finding the right doctoral thesis – an innovative research fair for medical students (United States)

    Steffen, Julius; Grabbert, Markus; Pander, Tanja; Gradel, Maximilian; Köhler, Lisa-Maria; Fischer, Martin R.; von der Borch, Philip; Dimitriadis, Konstantinos


    Introduction: The importance of research, as promoted by the CanMEDS framework, is widely acknowledged. Many medical students in Germany work on a research project as part of their doctoral thesis whilst still going to medical school. However, a significant amount of projects are abandoned unfinished, which leads to substantial wastage of resources. One reason for this is an information deficit concerning undergraduate research projects. Project description: To counteract this, we introduced an annual event at LMU Munich called DoktaMed with more than 600 visitors each year. It combines medical convention and research fair including keynote lectures, workshops and poster sessions as well as an exhibition of research groups and institutes. DoktaMed is a peer-to-peer event organized by a team of 40 students. Results: A needs analysis before its implementation underlined the information deficit as a possible cause for the high rate of abandoned projects. In the annual evaluation, visitors of DoktaMed rate the event with an average grade of 2.1 on a six-level Likert scale (n=558, SD=1.06, with "1=very good", "6=poor"). They stated to now feel better informed about the topic and regarded visiting DoktaMed as a worthwhile investment of time. Discussion: Students are generally satisfied with the event and feel better informed after visiting DoktaMed. However, many students never visit DoktaMed for various reasons. A possible improvement would be to present a greater number of clinical studies in addition to the laboratory work that DoktaMed focuses on now. Conclusion: Evaluation after six years of DoktaMed is very promising. Visitors seem to be better informed. Nevertheless there is space for improvement in order to get more students and more faculty members involved. More studies are needed to assess long-term effects. PMID:26413167

  20. [A doctoral thesis on occupational diseases from 1816: workers' diseases in the post-Ramazzinian era]. (United States)

    Carnevale, F


    No medical "classical" work has been in any way as successful as Ramazzini's De Morbis Artificum Diatriba. The book's success is confirmed by the constantly increasing number of new editions, emulations, translations and quotations and corresponding dissemination. As is proven by web access, our contemporaries continue to contemplate Ramazzini with admiration and wonder, confidence, devotion and curiosity and also as a means of seeking confirmation of the concepts that are variously presented. It is possible to describe a temporal phenomenon of "differential impact" of Ramazzini's work. Throughout the twentieth century, and especially on "celebrated" anniversaries (1900, 1913, 1914, 1933, 1964, 2000), many "tributes" to the author were recorded. During the nineteenth century in major European countries, but less so in Italy, Ramazzini's lesson was recorded as superseded "on an objective basis". The context had completely changed, as did both work and workers after a century-old continuity. Between the 1700's and the early 1800's Ramazzini dominated the field like a mountain in the desert; with editions of De Morbis in Latin and in translations following one on the other, with a positive cultural and popularizing impact on a public consisting of the international scientific and professional avant-garde. The means of dissemination consisted first and foremost of including all or part of the corpus of the Diatriba in "dictionaries" or "encyclopaedias" of medicine. Another means that was widely used, efficacious and typically academic, was through the doctoral theses discussed in all major European universities. Among these contributions was the thesis discussed in 1816 in Paris, by Louis-André Gosse of Geneva (1791-1873), which is presented in the previous pages in the translation from the French.

  1. [Historical studies and medicine. A study in Swedish doctoral thesis concerning history of medicine 1970-2004]. (United States)

    Qvarsell, Roger


    This article is a study in ninety doctoral thesis published in Sweden between 1970 and 2004 concerning history of the science of medicine and hospital care, patients and practicioners, causes of death and public health, doctors and nurses, health movements and lay medicine and other aspects of the history of medicine. A quantitative part of the study shows that most thesis have been written at departments of history or history of ideas, but sociological and mulitdisciplinary studies are also rather common. Only six of the thesis have been written at departments within the medical faculties. The second half of the 19th and the first half of the 20th centuries has been investigated more often than other historical periods. More than ninety percent of the thesis has been published in Swedish and concerns history of medicine in Sweden. A wide range of methods and theories has been used and history of medicine does not as a field deviate from historical research in general in this respect. A chronological bibliography of the ninety thesis ends the article. PMID:17575638

  6. Structural assignment and catagenetic behavior of macromolecular constituents of recent and fossil natural resins. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    van Aarssen, B.G.K.


    The thesis describes the results obtained by molecular organic geochemical investigations of fossil and recent natural resins. A major constituent of these plant exudates is a polymeric substance which is resistant to degradation and is thus likely to fossilize. Time and the rise of temperature and pressure upon burial may lead to a disintegration of the polymeric structures into smaller molecules which can contribute to oil formation. The aim of the study was to assess the mechanisms of depolymerization by investigating in detail the chemical structures of resin polymers and their catagenetic products. In nature two major types of resinous polymers are known to occur: polysesquiterpenoids and polyditerpenoids. The first part of the thesis, chapters 2-8, contains the results of investigations concerning the sesquiterpenoid type polymer. Chemical structures, occurrence and origin of both the polymer and its catagenetic products are described. The second part of the thesis, chapters 9-11, deals with the structures of diterpenoid polymers.

  7. Neutron experiments on nuclear magnetism in copper and silver. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Tuoriniemi, J.T.


    This thesis adds to the series of investigations on nuclear magnetism in metals performed during the past 20 years at the Low Temperature Laboratory of the Helsinki University of Technology. Collective behavior of nuclear spins is expected only at very low temperatures because the mutual interactions are extremely weak. To learn what the spin structure below the transition point in these metals is, neutron-diffraction experiments have been performed. The subject of this thesis is to present the results of neutron experiments on nuclear magnetism in copper and silver.

    In the thesis mechanistic studies on the sulfonation of mono-functionalized alkenes, viz. phenylalkenes, naphthylalkenes, alkenoic acids, alkadienes and cycloalkylidenes, mainly with sulfur trioxide are described. The main objective of the studies is to determine the effect of the substituents at the alkene moiety on the formation of the beta-sultones and carbyl sulfates and on their chemistry.

  9. Theoretical aspects, design, and characterization of dc superconducting quantum interference devices. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Ryhaenen, T.


    The summary of the thesis is divided into three sections. Section 2 discusses the modelling, dynamics, characteristics, and the noise performance of thin-film dc SQUIDs. Results of both numerical simulations and measurements are used to summarize the most important features of the SQUID dynamics. The dependence of the characteristics and noise performance on various SQUID parameters is discussed. Section 3 presents a more concrete description of the geometrical structures of thin-film dc SQUIDs. The fabrication of the devices is briefly discussed, emphasizing the factors that determine the resolution and reliability of the sensors. Several parasitic features of the SQUID, owing to coupling circuits and practical geometries, are presented and methods to avoid them are discussed. Finally, the optimization of the whole configuration of a dc SQUID magnetometer is analyzed. Section 4 summarizes the experimental results of low-noise dc SQUIDs presented in the thesis. The electronics for measuring low-noise SQUIDs are also discussed.

  10. Measurements of the structure and nucleation of vorticity in the (3)He superfluids. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Parts, U.


    This thesis reports experiments on rotating superfluid 3He, which were performed in the Low Temperature Laboratory during the period 1991-94, and which are published in a series of original publications. Rotation is particularly useful for creating various types of topological objecs, e.g. quantized vortex lines, in large quantities for systematic investigation. The author`s method to study them is the nuclear magnetic resonance (NMR) technique, which has been an important experimental tool in various fields of physics for about fifty years. In the case of superfluid 3He, NMR provides direct information on the spatial distribution of the order parameter field. Both superfluid phases of 3He, the A- and the B-phase, have been under investigation in this thesis work. In 3He-B the main concern has been the nucleation of singular vortices. This process involves an energy barrier, similar to a first order phase transition.

  11. Experimental investigation and numerical modelling of cyclones for application at high temperatures. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Bernard, J.G.


    This thesis describes a part of the research project High Temperature Gas Clean-up' (HTG), specifically for application in Pressurized Fluidized Bed Combustion (PFBC). The thesis involves research on cyclones, with specific application at high temperature. The flow pattern and the behavior of the particulate phase were investigated. Since the measurements at high temperature were complicated, many introductory experiments were made at normal conditions. This was also a good starting point for the modeling of the cyclone. Models which have been developed so far were based on operation at normal conditions and were validated under the same circumstances. Therefore, it was first attempted to make reliable measurements at normal conditions before the measurements at high temperatures were assessed.

  13. Transport phenomena in underground coal gasification channels (transportverschijnselen in ondergrondse kolenvergassingskanalen). Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Kuyper, R.A.


    Underground coal gasification is an attractive option to recover energy from thin deep-lying coal seams. By injecting air into the coal layer, combustible gases are formed underground which can be used to produce energy at the surface. During a coal gasification field test in Pricetown (USA), an open channel structure had formed underground. In this thesis, the wide range of transport processes occurring in such underground coal gasification channels has been studied. The principal aim of this study was to understand and describe the transport processes which determine the behavior of the gasification process. The main aspects of the gasification process have been studied separately. Due to this approach, the influence of the various aspects of the gasification process on the behavior of the process has become clear. In the first part of this thesis, the influence of geometrical aspects of the gasification channel on the natural-convection flow in the channel has been studied by considering the natural-convection flow in various differentially heated enclosures. This approach led to a fundamental study on natural-convection flows. The second part of this thesis is associated with the transport processes arising during gasification. Here, a simulation model has been refined step by step. In the final simulation model, all main transport processes occurring in a rectangular gasification channel are described.

  14. Reduction of nitric oxide over platinum, rhodium and platinum-rhodium single crystal surfaces. Doctoral thesis

    Siera, J.


    Although platinum and rhodium are introduced separately in the three-way catalyst, it is established that Pt-Rh alloy particles are formed during its performance. Despite the widespread use of the three-way catalyst and the intensive research on the catalytic properties of the pure metals, relatively little is known about the alloy system. In the thesis results are described for the NO-H2, NO-NH3, CO-O2 and CO-NO reactions on the surfaces of Pt, Rh and Pt-Rh alloy single crystals.

  15. Contribution to the Nonparametric Estimation of the Density of the Regression Errors (Doctoral Thesis)

    CERN Document Server

    LSTA, Rawane Samb


    This thesis deals with the nonparametric estimation of density f of the regression error term E of the model Y=m(X)+E, assuming its independence with the covariate X. The difficulty linked to this study is the fact that the regression error E is not observed. In a such setup, it would be unwise, for estimating f, to use a conditional approach based upon the probability distribution function of Y given X. Indeed, this approach is affected by the curse of dimensionality, so that the resulting estimator of the residual term E would have considerably a slow rate of convergence if the dimension of X is very high. Two approaches are proposed in this thesis to avoid the curse of dimensionality. The first approach uses the estimated residuals, while the second integrates a nonparametric conditional density estimator of Y given X. If proceeding so can circumvent the curse of dimensionality, a challenging issue is to evaluate the impact of the estimated residuals on the final estimator of the density f. We will also at...

  16. Spin dependent structure function g1 of the deuteron and the proton. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Klostermann, L.


    This thesis presents a study on the spin structure of the nucleon, via deep inelastic scattering (DIS) of polarized muons on polarized proton and deuterium targets. The work was done in the Spin Muon Collaboration (SMC) at CERN in Geneva. From the asymmetry in the scattering cross section for nucleon and lepton spins parallel and anti-parallel, one can determine the spin dependent structure function g(sub 1), which contains information on the quark and gluon spin distribution functions. The interpretation in the frame work of the quark parton model (QPM) of earlier results on g(sub 1, sup d) by the European Muon Collaboration (EMC), gave an indication that only a small fraction of the proton spin, compatible with zero, is carried by the spins of the constituent quarks. The SMC was set up to check this unexpected result with improved accuracy, and to combine measurements of g(sub 1, sup p) and g(sub 1, sup d) to test a fundamental sum rule in quantum chromodynamics (QCD), the Bjorken sum rule. The SMC results presented in this thesis are based on data taken in 1992 using a polarized deuterium target and polarized muons with an incident energy of 100 GeV, and 1993 data with a proton target and an incident muon energy of 190 GeV. Using all available data, the fundamental Bjorken sum rule has now been verified at the one standard deviation level to within 16% of its theoretical value.

  17. Statics and dynamics of a natural circulation cooled boiling water reactor. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Stekelenburg, A.J.C.


    Due to the strong interconnection of the various processes in the reactor vessel of a natural circulation cooled boiling water reactor (BWR), explaining the physics of both the statics and the dynamics of the Dodewaard reactor is not an easy task. In this thesis, the physics is studied through a combined experimental and theoretical investigation. The experiments are analyzed further with the use of the model, and the results of the model calculations provide ideas for new experiments. For an experimental study of the reactor behavior, measurement tools are required. Many relevant process variables are supplied by the power plant's data-logger, but a direct method for measuring the circulation flow rate is not available. Reactor behavior can be studied theoreticallly with the use of a complex computer code, based on a multi-node model. In this way, reliable results are obtained. In many cases, however, such a code is not easy to use, and the calculations require much computer time. Calculations based on a simple model have a lower reliability, but, as the model is clearer, provide more insight into the physics of the system. For this reason, a simple theoretical dynamical model for the main physical processes of the Dodewaard natural circulation cooled BWR is presented in the thesis.

  18. Isotopes of carbon monoxide in the free troposphere and their implications to atmospheric chemistry. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Mak, J.E.


    The thesis project was designed to provide information for the following questions: what is the oxidative capacity of the troposphere, and how are the source strengths of carbon monoxide partitioned. Because of its active role in tropospheric chemistry, carbon monoxide is important in determining the fate of a number of species, including hydroxyl radicals. (14)CO serves as a natural tracer for its destruction, as the source function can be well contrained. By determining the tropospheric inventory of (14)CO and calculating its source strength, one may realize the rate of destruction. Similarly, because certain sources have unique stable isotope signatures, an analysis of the stable isotopes provides information on the relative source strengths. A sampling system was built which allowed for the collection of large, whole air samples from an aircraft platform. CO was extracted and the isotopes were determined, and from these data an OH abundance was calculated using a 2-D transport model.

  19. Use of predictions in temperature control in buildings: A passive climate system application. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Lute, P.J.


    The thesis consists of two parts. The first part is a general part about predictive control in the indoor climate field. The second part deals with the control system implementation in the passive indoor climate system. The fundamentals, general principles and mechanisms of the class of predictive controllers and control strategies with a linear objective function are described in chapter 2. Chapter 3 deals with the typical characteristics of the indoor and outdoor climate, that have to be incorporated in a predictive control system to make it a successful and robust predictive indoor climate control system. A general scheme for a predictive indoor climate system, that has self-learning features, is described in Chapter 4. Chapter 5 introduces the passive indoor climate system to which a predictive control strategy is applied. Finally, in Chapter 6, a test facility for passive climate systems, referred to as the TU Delft test cell, is described.

  20. Commissions for environmental impact assessment: Their contribution to the effectiveness of environmental impact assessment. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Mostert, E.


    The thesis presents a theory on the feasibility of EIA Commissions and the way in which they can be modeled. The cases selected are the Dutch EIA Commission, the central Polish EIA Commission and the Hungarian Commission on Power Plants. Extensive literature research was conducted on these cases and a total of 79 persons, involved in EIA were interviewed. In addition to the three cases, a more limited literature study was conducted on the Canadian EIA panels. Sections discuss the questions what EIA is, what EIA Commissions are, what effective EIA is, how subjective EIA is and what complications this can give for the effectiveness EIA is, how subjective EIA is and what complications this can give for the effectiveness of EIA, what the potential contribution of EIA Commissions to the effectiveness of EIA is, and what role the decision-making culture plays in this.

  1. Dynamic modeling and control of integrated coal gasification combined cycle units. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Schoen, P.


    This thesis investigates the dynamic behavior and control of integrated coal gasification combined cycle units, operating in a load-following mode on the national grid. Startup, shutdown and accident related behavior are not considered. A conceptual 250 MW unit featuring an oxygen-blown pulverized coal gasifier according to the Shell Coal Gasification Process (SCGP) has been taken as the subject of a simulation study. An attempt at model validation has been made using experimental data from the SCGP demonstration unit in Deer Park, Texas. Using the concept of Model Predictive Control, sample constraints on gasifier conditions and syngas pressure profile were explicitly accounted for in the control algorithm. Whereas the former are found to be easily accommodated without any significant impact on load-following control, the latter inevitably lead to a deterioration in performance. Conclusions and recommendations on dynamic modeling and unit power control are provided.

  2. CVD techniques for the synthesis or modification of porous ceramics. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Dekker, J.P.


    Chemical Vapor Deposition (CVD) has been recognized as an important production method for thin films. In CVD gaseous reactants are introduced into a reactor in which they react to form a solid on a surface. This technology is widely used in the processing of micro-electronic devices. The CVD process for the densification of a porous preform to make up a matrix material is referred to as Chemical Vapor Infiltration (CVI). In particle Precipitation aided CVD (PP-CVD) an aerosol is formed, and the particles are precipitated on a substrate by introducing an external force for particle deposition. This thesis deals with the high temperature chemistry of the formation of titanium nitride and titanium diboride in CVD, CVI, and PP-CVD. It gives a concise presentation of the experimental work on high temperature chemistry of these CVD techniques.

  3. An Analysis on the Application of Rescale Range and Fractals in the Characterisation of English Alphabets in a Doctoral Thesis

    Directory of Open Access Journals (Sweden)

    Tajudeen Abiola


    Full Text Available This contribution presents an analysis on two key approaches to studying the characterization of English alphabets in doctoral thesis. The approaches (rescale range analysis (RSA and fractal characterization (FC are discussed from the simulation point of view. For RSA, Hurst exponent value was used for the string of English alphabets in composing doctoral abstracts of engineering-based research work. FC involves the combined application of Cantor dust knowledge and fractal box dimension estimate by box counting and probability. For the two approaches, four engineering-based doctoral abstracts were studied with the total length of 512 alphabets in each case. The average computerized rescale range value was found to increase with the increase in data length for all cases. The Hurst exponent values for all cases distinctively range between 0.4146 and 0.4873 (i.e. negative correlation. The relative percentage error computed for the estimated fractal box dimension of Cantor Dust when compared with the literature result was 15.7% (i.e. the algorithm used in this study for the estimate will tolerate maximum of 15.7% error for any study case: Comparisons of sorted alphabets by frequency and estimated fractal box dimension for four abstract cases range between 37% to 77% agreement. The average percentage agreement among the four cases sorted by frequency was 31.5% and the average was 43% for sorting done by estimated fractal box dimension (due to recognition of placement and timing of usage of the English language alphabets in the studied cases. The graphs of estimated probability and fractal box dimension distribution for the studied cases follows trend.

  4. Removal of dichloromethane from waste gases in a biological trickling filter. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Diks, R.M.M.


    Biological waste gas purification systems, especially biofilters, are increasingly applied in different branches of industry, not only for the elimination of odorous, easily biodegradable compounds, but also for the removal of toxic xenobiotics from waste gases. Although successful in most cases, a biofilter cannot be applied if large amounts of acidifying or inhibiting compounds accumulate in the filter material during the microbial degradation of the contaminants present in the waste gas. The thesis describes the development of a biological trickling filter, in which the above-mentioned problems can be easily dealt with. In this reactor the waste gas is forced to rise through a bed of inert packing material, on which a suitable microbial flora is immobilized. By the recirculation of a water phase through this system, acids produced are continuously removed from the filter bed and hence microbial activity is maintained. The flowing liquid phase also allows for the continuous neutralization and control of the optimal physiological conditions, i.e. temperature, pH and concentration of inhibiting compounds.

  5. Fluid dynamics of the freeboard in a fluidized bed reactor. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Verloop, W.C.


    The present study focuses on the fluid dynamics of the gas-particle freeboard flow, whereas a subsequent study will cover the chemistry. The objective of the present thesis is to increase the insight in the physical processes that govern the freeboard particle flow. Special attention has to be paid to the lateral transport of particles and the often observed phenomenon of a downflowing wall layer of solids, which has not been explained satisfactorily up to now. In order to achieve this, detailed experiments have to be performed which provide data on the local flow structure. In addition, the freeboard flow has to be modeled at least two-dimensionally, incorporating the essential physical processes. The resulting model of the freeboard flow should firstly be capable of predicting the local properties of both the gas flow and the particle flow. This prediction has to serve as a basis for the subsequent modeling of the freeboard chemistry. Secondly, the model should serve as a basis for studying the consequences of the scaling up a fluidized bed installation from lab scale to industrial size.

  6. Study of mid-latitude 5577A CI dayglow emissions. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Hume, E.E.


    Summary of thesis: The green line (5577angstroms) is a bright, persistent component of the visible airglow. It is produced by an electric quadruple transition from the metastable second excited state (1So) to the first excited state (1D2) of atomic oxygen. These two excited states all lie in the same electron shell of the atom and have the same electron configuration as the ground state of 1s22s22p4, which is the 3P2,1,0. This emission is present in both the daytime and night airglow and in the aurora, and despite a long history of study it is still not fully understood. The emission in the dayglow and the nightglow is relatively homogeneous spatially and global in coverage. In the aurora, the emission is much brighter than the airglow, high structured and very localized being restricted to higher latitudes. The structure of the 5577angstroms emission with altitude and the chemistry responsible for the production of the emission are complex. The vertical structure for the emission has two distinct layers in the airglow each with its own set of production and loss mechanisms. the chemistry for either of these layers is not completely known. The auroral emission is not understood either since it overlaps the upper and lower layer altitudes and it tends to contain some parts of the chemistry of both layers as sources and losses.

  7. Hydrodynamics and morphodynamics of shallow tidal channels and intertidal flats. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Friedrichs, C.T.


    In this thesis, mechanisms which control morphodynamics of shallow tidal embayments are investigated analytically. In the process of exploring these mechanisms (specifically asymmetries in bottom stress), Tau, basis momentum and mass balances which govern flow in these systems are clarified. Temporal asymmetries in Tau are investigated via a new perturbation scheme which quantifies nonlinear processes and combines geometric controls on asymmetry into a single non-dimensional parameter. Implications of spatial asymmetries in Tau are investigated through stability criteria based on a uniform distribution of Tau. Morphologic observations of both tidal channels and intertidal flats are consistent with a uniform distribution of Tau at equilibrium. Investigation of morphodynamic mechanisms leads to scalings of momentum and continuity which diverge from classical models. Scalings for prismatic channels with strong tidal asymmetries indicate friction often dominates acceleration in the momentum equation. The resulting zero-inertia balance gives a time-varying diffusion equation which requires along-channel amplitude to decay. Uniform Tau justifies a new scaling of continuity for exponentially-shaped channels. In such channels, along-channel gradients in tidal velocity are small and are often dominated by gradients in cross-sectional area. The resulting first-order wave equation allows only amplitude, forward propagating waveforms which are independent of channel length. Tidal channels Hydrodynamics, Tidal flats.

  8. Reputation strength as a determinant of faculty employment: a test of the step-down thesis among clinical psychology doctoral programs. (United States)

    Roberts, Michael C; Ilardi, Stephen S; Johnson, Rebecca J


    This study tested the folkloristic belief that doctoral degree recipients who pursue academic careers typically wind up at institutions ranked lower in prestige than the institutions at which they trained (the step-down thesis). We used a database of faculty members in 150 clinical psychology doctoral programs accredited by the American Psychological Association, and compared each faculty member's training institution with the current employing institution on three distinct reputation ranking systems: The Center (University of Florida, Gainesville) for overall university reputation, the National Research Council (Washington, DC) for doctoral degree department reputation, and the news magazine, U.S. News and World Report ranking for clinical psychology training program reputation. Although support for the step-down thesis was found across all three ranking systems, a disproportionately large number of professors were also observed to move laterally in terms of their employing institution's reputation.

  9. Be collisions. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Veenhof, R.J.


    The Helios experiment was proposed in 1983 to investigate in detail the origin of low mass lepton pairs. The Helios setup combines an electron spectrometer, a muon spectrometer, a photon detector, almost hermetic calorimetry and a device to measure the multiplicity. The Helios detector is described in Chapter 2.0 with particular emphasis on the performance of the drift chamber system. The event selection and the reconstruction of the muons is described in Chapter 3.0. Chapter 4.0 summarizes the current knowledge of the decays of mesons into low mass muon pairs. The author's own measurements of meson properties are presented in Chapter 5.0. The question whether one needs anomalous pairs to explain the data, is answered in Chapter 6.0. Helios reaches the conclusion that there is no evidence for the production of anomalous pairs at central rapidity and low p[sub T] in pBe collisions. This result complements the recent finding of the RISK experiment, which is also able to observe Dalitz decays, that low mass lepton pair production in the forward region in pi(-)C interactions is compatible with meson decays.

  11. Reflections on the doctoral thesis Race in Antioquia is unique and is not degenerated = Reflexiones sobre la tesis doctoral “La raza antioqueña es única y no está degenerada”

    Directory of Open Access Journals (Sweden)

    Jaime Carrizosa Moog


    Full Text Available In several countries, totalitarianism, fascism and national-socialism had racial topics as core policies. Other countries did not necessarily have a liberal thinking on this specific matter, and also approved discriminatory laws. In Latin America, eugenics had a great impact on public health policies during the first half of the 20th century, and gave rise to stigmatization of ill persons and of different races. Ninety years after its publication, a doctoral thesis on the race in Antioquia, Colombia, may still have validity.

  12. The Libyan doctors' brain drain: an exploratory study

    Directory of Open Access Journals (Sweden)

    Bredan Amin


    Full Text Available Abstract Background Medical emigration from developing to developed countries is a well established phenomenon of substantial importance. Though Libya is classified as an upper-middle income country, it has been affected by this trend. This study was undertaken to identify some of the possible reasons behind the emigration of Libyan doctors and factors that might motivate them to return. Findings Seventy-four completed questionnaires were analysed. Median age of the respondents was 43 years (33-60 and median duration of stay outside Libya was 15 years (6-29. Most of the participants were resident in Europe (66%. The desire to further their education and research was the main reason given by 88% of the respondents for leaving Libya, while 50% of them gave that as the main reason for staying abroad. One-third of the respondents (31% cited economic factors as the main reason for not returning. None of the respondents ruled out returning to Libya, and about half of them stated that they definitely or probably will return to Libya. 58% ranked reform of the Libyan health system as the most important reason that could induce them to return to Libya. Conclusion The study shows that reforming the health care system in Libya might induce some of the physicians who moved abroad mainly for educational and economic reasons to return to Libya to practice medicine.

  16. Is the medical brain drain beneficial? Evidence from overseas doctors in the UK. (United States)

    Kangasniemi, Mari; Winters, L Alan; Commander, Simon


    The 'beneficial brain drain' hypothesis suggests that skilled migration can be good for a sending country because the incentives it creates for obtaining training increase that country's net supply of skilled labour. Necessary conditions for this hypothesis to work are that the possibility of migration significantly affects decisions to take medical training and that migrants are not strongly screened by the host country. We conducted a survey among overseas doctors in the UK in 2002, which suggested that neither condition is likely to be fulfilled. Apart from the 'beneficial brain drain' argument, the survey findings also cast light on the backgrounds and motives of migrant doctors, and finds evidence that there could, nonetheless, be other benefits to sending countries via routes like remittances and return migration.

  17. Should Research Thesis be a Prerequisite for Doctor of Medicine Degree? A Cross-sectional Study at Jordan University of Science and Technology

    Directory of Open Access Journals (Sweden)

    Aisha Gharaibeh


    Full Text Available Background: University based research is an integral part of many prestigious medical schools worldwide. The benefits of student-conducted research have long been highlighted in the literature. This article aims to identify the insights of medical students concerning research training, including perceived hurdles in the way of conducting research, and the utility of a research thesis in acquiring a Doctor of Medicine degree.Methods: A total of 808 medical students at Jordan University of Science and Technology were selected by random sampling with a confidence level of 95%. A survey was constructed by a group of students through literature review and group discussions. The survey utilized polar and Likert scale questions to collect data from the students. Statistical inferences were then obtained through analysis of means and one sample t-test of the hypothesis.Results: A total of 687 students filled out the survey (85%. Analysis shows that respondents have a strong and positive attitude towards research. The respondents with past research experience constituted 14.3% of those surveyed. Those respondents identified the barriers faced by them during their experience. The students showed high degree of agreement that a research thesis should be a prerequisite for graduation with statistical significance of p-value ≤0.05.Conclusion: Modifying the curriculum to include research methodology is recommended, and developing it to incorporate a thesis as a requirement for graduation may be advised upon further review.

  19. Nuclear reactor noise investigations on boiling effects in a simulated MTR-type fuel assembly. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Kozma, R.


    Boiling experiments at HOR have a relatively long history that began more than a decade ago. Following some introductory out-of-pile experiments, a boiling setup was operating at HOR between 1984 and 1986. Based on the experience of that setup, a new boiling experiment, NIOBE (Noise Investigations On Boiling Effects), has been designed. The NIOBE setup has been in operation since the end of 1986. The present work contains results of experiments performed between 1988 and 1991, with the exception of Chapter 5, in which experiments with the predecessor of NIOBE are treated. The thesis is based on results of experiments performed at the NIOBE loop located in a research reactor (HOR).

    Niu, J.


    The contents presented in this thesis consist of four principal parts: (1) the critical review of turbulence CFD (Computational Fluid Dynamics) techniques and their application in building air flow study, and the experimental evaluation of the widely used k-epsilon turbulence model for in-room air flow situations; (2) the development of a thermodynamic mathematical model for cooled-ceiling air-conditioning systems, and the enhancement of an existing computer code ACCURACY, and the experimental validation of the convective parameters involved in the models; (3) the combined use of building dynamic simulation and CFD technique for the investigation of thermal comfort and ventilation effectiveness performance of three typical air-conditioning systems, the air-panel type cooled-ceiling (ACC) system, and the water-panel type cooled ceiling (CC) system; and (4) the use of the dynamic model coupled with air-handling-unit (AHU) and primary equipment models to simulate the annual energy consumption of CC systems and all-air systems and to estimate thermal performances of some passive cooling schemes, especially the evaporative free-cooling scheme. The review of the state-of-the-art of turbulence modeling shows that the k-epsilon turbulence model still remains the most-widely used engineering model.

  1. Trapping and diffusion of noble gas atoms in some off-stoichiometric ceramics studied by thermal desorption spectrometry. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Hoondert, W.H.B.


    The thesis deals with the mobility of small noble gas atoms, mainly helium, in ceramic materials with high defect concentrations. Hence, two subjects are covered: diffusion and defect physics. The experimental technique employed is Thermal Desorption Spectrometry (TDS). An introductory outline of TDS is given. The present study was initiated for various reasons. First of all, research on helium retention and mobility behavior, such as bubble nucleation and subsequent bubble migration, in potential fusion reactor wall materials (which some of the ceramics are) is of practical interest. Secondly, because the ceramic materials investigated in the present work have defect concentrations on the order of percents, and because they are binary compounds where in principle more defect types can be present than in pure materials, the defect physics is more complicated and diverse than e.g., in simple metals. Finally, high defective materials can serve as a model system for thin films produced by Ion Beam Assisted Deposition (IBAD). TDS as an analytical tool is of key importance to be able to control the IBAD process, and for the understanding of the atomic-scale phenomena involved.

  2. Calculation of phase stability in Zr-Nb-Ru using LMTO and the cluster variation method. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Becker, J.D.


    Progress in a long-standing objective in computational materials science, the calculation of alloy phase diagrams from first-principles, has been paced by the associated problems of accurate yet efficient total-energy calculations and statistical approximations of the alloy partition function. The former is well understood, and the evolution of Density-Functional Theory (DFT) to computationally suitable methods using the Local-Density Approximation (LDA) is a renowned (though, arguably, a qualified) success. The high precision required of the total-energy band-structure methods for phase-equilibrium calculations is attainable for most chemical systems. The connection between the total-energy calculations and a general solution to the Ising problem is provided by a cluster expansion in a series of multi-atom interaction energies. This rigorous expansion my be inverted to calculate the total energy of any lattice configuration using the multi-atom interactions. Two main aspects of the cluster expansion method remain unresolved: the convergence of the expansion and the effect of strain energy on the convergence. These two issues are central to this thesis, and a major portion of this study is devoted toward a resolution.

  4. Neutron Transport with Anisotropic Scattering. Theory and Applications. Doctoral thesis prepared at SCK-CEN and defended in 2005

    International Nuclear Information System (INIS)

    This thesis is a blend of neutron transport theory and numerical analysis. We start with the study of the problem of the Mika/Case eigenexpansion used in the solution process of the homogeneous one-speed Boltzmann neutron transport equation with anisotropic scattering for plane symmetry. The anisotropic scattering is expressed as a finite Legendre series in which the coefficients are the scattering coefficients'. This eigenexpansion consists of a discrete spectrum of eigenvalues with its corresponding eigenfunctions and the continuous spectrum [-1,+1] with its corresponding eigendistributions. In the general case where the anisotropic scattering can be of any (finite) order, multiple discrete eigenvalues exist and these have to be located to have the complete spectrum. We have devised a stable and robust method that locates all these discrete eigenvalues. The method is a two-step process: first the number of discrete eigenvalues is calculated and this is followed by the calculation of the discrete eigenvalues themselves, now being able to count them down and make sure none are forgotten. During our numerical experiments, we came across what we called near-singular eigenvalues: discrete eigenvalues that are located extremely close to the continuum and hence lead to near-singular behaviour in the eigenfunction. Our solution method has been adapted and allows for the automatic detection of such a near-singular eigenvalue. For the elements of the continuous spectrum [-1,+1], there is no non-zero function satisfying the associated eigenequation but there is a non-zero distribution that does satisfy it. It is not feasible to compute a distribution as such but one can evaluate integrals in which this distribution appears. The continuum part of the eigenexpansion can hence only be characterised by its (angular) moments. Accurate and fast numerical quadrature is needed to evaluate these integrals. Several quadrature methods have been evaluated on a representative test

  5. On the bifurcation of blood vessels--Wilhelm Roux's doctoral thesis (Jena 1878)--a seminal work for biophysical modelling in developmental biology. (United States)

    Kurz, H; Sandau, K; Christ, B


    Wilhelm Roux's doctoral thesis described the relationship between the angle and diameter of bifurcating blood vessels. We have re-read this work in the light of biophysics and developmental biology and found two remarkable aspects hidden among a multitude of observations, rules and exceptions to these rules. First, the author identified the major determinants involved in vascular development; genetics, cybernetics, and mechanics; moreover, he knew that he could not deal with the genetic and regulatory aspects, and could hardly treat the mechanical part adequately. Second, he was deeply convinced that the laws of physics determine the design of organisms, and that a necessity for optimality was inherent in development. We combined the analysis of diameter relationships with the requirement for optimality in a stochastic biophysical model, and concluded that a constant wall-stress condition could define a minimum wall-tissue optimum during arterial development. Hence, almost 120 years after Wilhelm Roux's pioneering work, our model indicates one possible way in which physical laws have determined the evolution of regulatory and structural properties in vessel wall development.

  6. To redeem what could be redeemed. A vitalistic interpretation of Hannah Arendt’s doctoral thesis ‚On the concept of love in Augustine’.

    Directory of Open Access Journals (Sweden)

    Rafał Zawisza


    Full Text Available This article is a presentation of Hannah Arendt’s doctoral thesis publishedin 1929 and devoted to the notion of love in Augustine (Der Liebesbegriff beiAugustin. Its aim is to demonstrate the originality of Arendt’s work towards hermajor influence and object of criticism – the philosophy of Martin Heidegger. Herconcept of natality, derived from Augustinian thought, opposes to being-towards--death. This movement makes a different conception of subjectivity possible: Heideggerianegocentrism can be substituted by a plurality. Vitalism (as proposed by AgataBielik-Robson is noticeable in the interpretational efforts of Arendt and defendsa particular subjectivity against dissolution of any kind into Wholeness. Simultaneously,a vision of a community is formed – the community of equals constructedthanks to the recognition of contingency in conditio humana. In other words, herargument overcomes claims to absolute freedom. Reflections from the “pretheologicalsphere” (Arendt take the form of philosophical anthropology, crucial to subsequentArendtian thought. Speculations concerning a notion of God are linkedwith the dissimilar approaches to a neighbor’s love. This is reflected in the problemof the constitution of dependent subjectivity, the main feature of which is a dialecticallyunderstood gratitude: the recognition of one’s dependence is a first step toovercoming it. It corresponds with a complicated attitude towards modernity farfrom simple resolutions: a sense of historicity builds a strategic position as a conditionof successful emancipation.

    Gail, Matthias; Grün, Norbert; Scheid, Werner


    Coupled channel calculations are performed for electron-positron pair production in relativistic collisions of heavy ions. For this purpose the wavefunction is expanded into different types of basis sets consisting of atomic wavefunctions centred around the projectile ion only and around both of the colliding nuclei. The results are compared with experimental data from Belkacem et al (1997 Phys. Rev. A 56 2807). This work is part of the doctoral thesis of Matthias Gail, Giessen (D26) 2001.

  9. A positionism epitomology applied to small group decision-making in radioactive waste management. Doctoral thesis prepared at SCK-CEN and defended in 2004

    International Nuclear Information System (INIS)

    The article refers to an abstract of a doctoral thesis. Assuring the safety of technological developments is becoming one of the most important tasks in society. For nuclear waste repositories, it is important to know what will remain valuable of current performance and safety assessments within a few hundred years. The core of the PhD concerns the meaning that can be attributed to safety assessments. This study develops a new philosophical theory to explain how small group decision-making on technoscientific problems takes place. It is applied to the specific problem of decision-making on radioactive waste disposal and its related risk assessment. The new philosophical theory is based on Latour's interactionism theory, which in its essence states that facts are only facts if they are accepted by the network. The theory adds that fact-building or decision-making happens in a certain context by interaction of different context elements. The word context has a very specific meaning. It refers to a problem solving situations in which individuals work out a problem framing and use attitudes, personalities, group cultures, and objects. Decisions or fact-building within the group will happen by interaction between these context elements that will get different hierarchical positions and lead to contextual dissonance reduction. This is called positionism. An international questionnaire has been carried out asking for estimations by technologists and scientists of the risks and uncertainties of a high level waste repository on the one hand and their personality, group culture and background characteristics on the other hand. Two important indicators occur. High neuroticism -a personality measure indicating the general tendency to experience affects such as fear, sadness, or distrust- correlates with high assessments of the waste repository risks. Scientists with high confidence in science give significant lower estimations of the repository risks. These results illustrate

  10. The safety culture according to a comprehensive approach. A contribution to risk governance within complex systems. Doctoral thesis prepared at SCK-CEN and defended in 2004

    International Nuclear Information System (INIS)

    The article refers to an abstract of a doctoral thesis. This PhD is based on two evolutions within the society concerning the way to manage modern risks. It is more and more acknowledged that, firstly, rational scientific models are no longer capable to explain and manage the complexity and the diversity of risks. Secondly the supporters of a democratic conception of the risk governance claim that the risk management can benefit from the participation of the lay people to the debate. Within this framework, the study of safety culture, according to a bottom-up and comprehensive approach, in the field of the social sciences, represents an opportunity to make concrete the risk governance principle within complex system (such as a nuclear power plant and a nuclear research centre). The objectives of this PhD are the following: to appreciate the participation of the workers to the debate of the risk management within organisations; to present the lessons which can be drawn from this exercise and finally to investigate the safety culture of different groups of workers adopting an alternative view as compared to the vision as formulated in the present texts of the IAEA.The methodology was based on two techniques: observation and Focus Group. The observations were planed to feed further the Focus Group discussions with concrete examples of situations at work. We organized different Focus Group discussions with different kinds of workers (workers, managers, safety officers) in order to collect the social representation relating to the safety, the organization, the technology, the socio-economical environment and the work of each of these groups, both in the Belgian Nuclear Research Centre and in the Nuclear Power Plant of Tricastin in France. The results confirm firstly the relevance of developing a multidisciplinary theoretical framework of safety culture drawing its inspiration from sociology, social psychology, anthropology, etc. This multidisciplinary approach allows

  11. Congenital malformations induced by ionizing radiation in mouse embryos: investigating molecular changes. Doctoral Thesis Prepared at SCK-CEN and Defended in 2006

    International Nuclear Information System (INIS)

    Irradiation of the mammalian embryo during development results in diverse effects depending on the dose and the specific gestational phase at irradiation. In this work cellular and molecular changes associated with X-irradiation of embryos were therefore investigated at both early and late gestational stages at the moment of radiation exposure. Our goal was to find biological markers indicative of teratogenic effects of radiation, and provide a holistic model of the impact of irradiation during early and late development. In the first part of this doctoral thesis, we investigated telomere length in the irradiated and non-irradiated embryos bearing different p53 genotypes and malformation status as telomere shortening was associated with neural tube defects in mTR-/- embryos. Moreover, the loss of telomere function has been shown to elicit DNA damage checkpoints and p53-dependent apoptosis in vitro. We conclude that telomere shortening is associated with the malformation status as well with the p53 genotype. These data assign telomere length as a potential predictor of a malformed phenotype, a feature that is modulated according to the p53 genotype and the developmental stage at the moment of irradiation. In the second part of this work, we focused on a specific malformation phenotype, namely: forelimb defect. To identify potential genes involved in the radiation-induced forelimb teratogenesis, we investigated differential gene expression between irradiated and non-irradiated fetuses using RT-q-PCR. The results indicate that forelimb defects observed in p53 wild type fetuses irradiated at the organogenesis period was due to excessive cellular death as shown by the high expression of the pro-apoptotic factors caspase-3 and Bax. This suggestion was supported by the positive TUNEL assay performed on forelimb tissue sections of malformed irradiated fetuses. Moreover, overexpression in malformed fetuses of MKK3 and MKK7, both members of the stress-activated MAP kinase

  15. Spins of resonances in reactions of neutrons with (238)U and (113)Cd. Doctoral thesis; Spins van resonanties in reacties van neutronen met (238)u en (113)cd

    Energy Technology Data Exchange (ETDEWEB)

    Gunsing, F.


    In this thesis experiments are described that have lead to the assignments of spins to a large number of resonances in reactions of epithermal neutrons with the nuclei (238)U and (113)Cd. When a neutron is captured by an atomic nucleus, a compound nucleus is formed which is in a highly excited state with an energy of the order of the neutron binding energy. If the kinetic neutron energy is varied around a state of the compound nucleus, one observes a peak in the cross section. This is called a resonance in the reaction. Dependent on the amount or orbital momentum l that the neutron adds to the system, the resonances are indicated with spectroscopic notations as s- and p-waves for l = 0 and 1 respectively. The purpose of this thesis is to determine the spins of such resonances.

  16. Kinetics of the microbial degradation of oil in soil slurry reactors. Doctoral thesis; Kinetiek van de microbieele afbraak van olie in grondslurry-reactoren

    Energy Technology Data Exchange (ETDEWEB)

    Geerdink, M.J.


    In recent years biological decontamination of water and soil has become increasingly popular. Several processes have been designed using this technique. One of these techniques is the soil slurry process designed at the department of Biochemical Engineering at the Delft University of Technology. The slurry process makes use of the so called DITS (Dual Injected Turbulent Suspension) reactor and one or more air agitated suspension reactors. The need for a more fundamental knowledge of the microbial oil degredation in the reactors was the starting point of the thesis. The main aim of this research project was to predict required residence times of oil contaminated soils during microbial remediation in a slurry reactor.

  17. Agency doctorates

    International Nuclear Information System (INIS)

    Staff members of the Agency working at the Seibersdorf laboratory are continuing to achieve high academic distinction. Two more - both Austrian - have now been awarded the degree of Doctor of Agriculture. Joachim Kramer, who is 26, graduated from the Hochschule fur Bodenkultur in 1967 with the degree of Diplom-Ingenieur and then started work in the plant breeding and genetics section of the laboratory under the direction of Dr. Knut Mikaelsen. The results of the research work he carried out were accepted as the subject of a thesis for which he has now been granted his doctorate. The doctoral promotion took place on 30 June, at a ceremony attended by Dr. Andre Finkelstein, Deputy Director General for Research and Isotopes. The subject of Dr. Kramer's thesis was a comprehensive study of the mutagenic effects of fast neutrons and gamma rays, and the influence of various modifying factors such as water content, oxygen and metabolic state of seeds at the time of irradiation. This work has contributed significantly to the understanding of the mechanisms by which these two types of ionizing radiation produce mutations in seeds. The knowledge gained will be of great importance in the efficient use of ionizing radiation in practical plant breeding. Paul Wassermann, who is 33 years old, joined the Agency in 1965. He, too, graduated from the Hochschule fur Bodenkultur as Diplom-Ingenieur in agriculture, having graduated with honours previously from the agricultural secondary school at Raumberg, Austria, in 1958. Dr. Wassermann's own words may be used to explain how he came to gain his doctorate. 'In October, 1966, I completed my studies at the Hochschule,' he writes. 'I was employed at the Agency laboratories in Seibersdorf, working in the plant and soils group. Encouraged by the interesting research which was performed there, a thesis entitled 'the Fate of Nitrogen in Submerged Rice Soils' was started, which finally led to the doctor's degree in Agriculture in June this year

  19. Interferometric and acoustic measurements in superfluid (3)He-B and wetting studies in (3)He/(4)He mixtures. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Alles, H.


    In this thesis work superfluid (3)He was investigated by two methods. First, ultrasonic experiments on (3)He-B were carried out using two coincident zero sound pulses. The second technique is optics, a novel method for ultra low temperatures. The developed method, two-beam interferometry, was employed successfully for studies of wetting phenomena in liquid (3)He/(4)He mixtures as well. This publication contains the results of a acoustic spectroscopy on (3)He-B. Most importantly, the real squashing collective mode (rsq) was excited by two simultaneous sound pulses yielding two phonon absorption (TPA). This nonlinear phenomenon was applied to study the dispersion relation of the rsq-mode. Zeeman splitting of the nonlinearly excited rsq-mode was investigated in a magnetic field. By means of TPA, an anomalous behavior was found also near the pair-breaking edge.

  2. Agency doctorates

    International Nuclear Information System (INIS)

    Mr. Wen-chuan Li of China has become the first student to obtain a doctor's degree as a result of research work carried out in the Agency. Mr. Li, who is 33, graduated as a Bachelor of Agriculture at Taiwan Provincial Chung-hsing University in 1960 and in 1966 was granted a fellowship to study mutations in plant breeding at the Agency's Seibersdorf Laboratory near Vienna, under the direction of Dr. Knut Mikaelsen, a professor of the University of Bergen. The Hochschule fur Bodenkultur of Vienna accepted the research as being suitable for a thesis and have now granted the degree of Doctor of Agriculture. The subject of the thesis was modifying factors influencing the mutagenic effects of alkylating agents as compared with ionizing radiations in barley. Alkylating agents are involved in the use of chemicals as a means of changing the characteristics of seeds to bring about changes aimed at improving the quality of crops. Mr. Li's work is regarded as a significant contribution to the understanding of the mechanics by which mutations are induced, to the efficient use of chemicals and ionizing radiations in practical applications, and to the efforts of the Agency in collaboration with the Food and Agriculture Organization to benefit food supplies. Mr. Li has now completed his fellowship with the Agency and has been appointed an Assistant Professor in Plant Breeding at Taiwan Provincial Chung-hsing University. The photograph, taken in the plastic hot house at Seibersdorf, shows him studying rice plants grown from seeds subjected to irradiation. Another noteworthy achievement is that of Mr. Karl-Franz Lacina, a security guard at the Agency's headquarters.

  3. Optimization of patient doses, linked to image quality, in vascular radiology. Doctoral thesis prepared at SCK-CEN and defended in 2005

    International Nuclear Information System (INIS)

    Vascular radiology includes procedures in which the radiologist or other medical specialist uses the radiological image to diagnose or treat a specific vascular structure. In the published MIRA-2004 report (Milieu- en natuurrapport Vlaanderen) is mentioned that in 2001 the diagnostic vascular procedures comprised only 0.9% and the interventional (cardiology) procedures only 0.4% from the total number of performed radiological medical examinations in Flanders. Notwithstanding the frequency is low, their contribution to radiation exposure in medicine is considerably higher in respect to all X-ray examinations. Due to the complexity of these procedures, the application of the ALARA-principle, keeping doses as low as reasonably achievable without jeopardizing image quality, is a great challenge. It is obvious that optimization of patient doses necessitates a reliable insight in dose levels associated with the different examinations. However, in Belgium there is a great lack of quantitative data in vascular radiology and no explicit instructions are available on how the work could be done practically. Therefore, the first purpose of the study was to define, to measure and to calculate doses to patients in 7 different hospitals. In the thesis, patient doses are measured and calculated for 3 specific vascular procedures: angiography of the lower limbs, angiography of the carotid arteries and cerebral embolisation. The doses are evaluated against different technical parameters of the equipment and of the working procedure. In view of optimization purposes, a protocol for performing dose audits in vascular radiology is suggested. From the results and conclusions in this study, some practical guidelines could be given for the radiological protection of the patient. For 158 patients, relevant parameters as tube voltage (kVp), tube load (mAs), field size, number of frames, fluoroscopy times etc. were recorded.

  4. Reactivity of surface carbonaceous intermediates. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Koerts, T.


    The study has concentrated on two reactions both related with carbon-carbon bond formation on transition metal catalysts. The first concerns the influences of a vanadium promoter on the kinetics of elementary reaction steps upon synthesis gas conversion on a rhodium catalyst. The second is related to the general problem of initiating a carbon-carbon bond between two methane molecules. Both reactions occur via reactive C1 surface intermediates. These surface species were created from CO and CH4 respectively. Mainly transient kinetic techniques were used which were combined with some quantum chemical calculations. The influence of a vanadium promoter on the formation and intrinsic reactivity of CHx species adsorbed on rhodium catalysts, for hydrogenation, chaingrowth and CO insertion, has also been investigated. On rhodium catalysts a very reactive C1 intermediate was found to be formed from dissociative CO adsorption. The formation of the surface species was found to be enhanced by vanadium promotion, which lowers the activation energy for CO dissociation.

  8. A legal analysis of the use of ionising radiation in medical hospital practice: an inquiry into the influence of prevention and precaution on health protection and liability. Doctoral thesis prepared at SCK-CEN and defended in 2004

    International Nuclear Information System (INIS)

    The article refers to an abstract of a doctoral thesis. From a legal perspective there exists a clear need for a general framework describing conditions and consequences of risk management in the field of high technology. Despite the existence of many kinds of Safety Procedures and Soft Law, specific guidelines are lacking for regulators and courts, especially in case of scientific controversy and uncertainty about the health effects of an activity or a product such as low doses of ionising radiation, electro-magnetic fields, genetically modified organisms, PCB's in salmon etc. The research of the PISA Project on Legal Aspects and Liability has been focussed on the medical applications of ionising radiation. The safety approach depends on the risk characterisation and differs for stochastic and deterministic effects. The most important objective was to find liability or funding systems which can cope with these differences, in particular between dose limits (as for the nuclear industry), reference dose levels foreseen in the EC medical Directive (as for nuclear medicine), and Optimisation referring to the ALARA principle. Risk assessment and risk management that are based on traditional narrow risk-assessment models have to be revised in the light of the Precautionary Principle. This principle urges policy-makers to adopt a broader, more pluralistic approach, considering the societal equilibrium, i.e. the general interest of the activity at stake, the general impact of individual protective measures and the existence of reasonable alternatives from a sociological, economical, scientific and technological point of view. One of the characteristics of the Precautionary Principle relates to our opinion to the collective damage to human health, i.e. a detriment that relates to a group of people. Nevertheless, as a result of the application of the Precautionary Principle, we believe that in case of individual damage the standard of care shall be more and more defined

  12. Doctors Today

    LENUS (Irish Health Repository)

    Murphy, JFA


    Doctors’ relationship with patients and their role in society is changing. Until the 1960s doctors concentrated on the welfare of patients with less emphasis placed on patients’ rights1. Over recent decades there has been increasing empowerment of the individual across all facets of society including health care. Doctors continue to be perceived as having expertise and authority over medical science. Patients, however, now hold sway over questions of values or preferences. We all must be aware of this change in the doctor- patient interaction. We need to be more aware of the outcomes that patients view as important. The concept of shared decision-making with the patient is now widely appreciated. The process involves a change in mind set particularly for doctors who trained in an earlier era.

  5. Current management for improved railgun performance. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Beno, J.H.


    Continued railgun development toward high-energy devices that launch useful projectiles and have a lifetime of hundreds to thousands of shots, requires progress in two related aspects of accelerator design: (1) rail containment structures must be made capable of withstanding greater rail repulsion forces, without causing accelerators to become too bulky for their intended use; and (2) rails must sustain very minor heat-related damage during projectile launch. The potential for managing rail current and its distribution to alleviate the two aforementioned problems is investigated. Techniques for calculating pulsed, rail current distribution, in the infinite-conductivity approximation, and resultant projectile force are developed. Then, passive, current management methods -- involving multiple rail pairs to distribute currents and rail-repulsive forces in a few, evenly-spaced, radial directions, for easier rail containment -- are explored. Optimized multi-rail, railgun cross sectional shapes that produce more projectile force than conventional two-rail railguns operating under the same local peak current density constraints are determined. These railguns have nontraditional bore shapes, i.e., not square or round. The use of neighboring, current-carrying conductors to actively influence rail current distribution is then studied.

  6. Fault-tolerant and efficient parallel computation. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Shvartsman, A.A.


    Recent advances in computer technology made parallel machines a reality. Massively parallel systems use many general-purpose, inexpensive processing elements to attain computation speed-ups comparable to or better than those achieved by expensive, specialized machines with a small number of fast processors. In such setting, however, one would expect to see an increased number of processor failures attributable to hardware or software. This may eliminate the potential advantage of parallel computation. We believe that this presents a reliability bottleneck that is among fundamental problems in parallel computation. We investigate algorithmic ways of introducing fault-tolerance in multiprocessors under the constraint of preserving efficiency. This research demonstrates how in certain models of parallel computation it is possible to combine efficiency and fault-tolerance. We show that in the models we study, it is possible to develop efficient parallel algorithms without concern for fault-tolerance, and then correctly and efficiently execute these algorithms on parallel machines whose processors are subject to arbitrary dynamic failstop errors. By ensuring efficient executions for any patterns of failures, the efficiency is also maintained when failures are infrequent, or when the expected number of failures is small.

  7. Vibrational spectroscopic studies of adsorbates on bimetallic surfaces. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Kuhn, W.K.


    In this work, well-defined bimetallic surfaces have been studied using carbon monoxide adsorption in conjunction with infrared reflection absorption spectroscopy (IRAS). These studies have indicated that for CO adsorbed on Cu overlayers, the bond between the CO and the Cu adatoms is comprised of both pi-back-donation and polarization interaction components. The sum of the contributions from these effects determines the observed bond strength with the observed CO stretching frequency being determined by the relative contributions of the components. In addition, it was determined that IR spectra of adsorbed CO show a remarkable sensitivity to surface structure. Three-dimensional Cu clusters, well-ordered two dimensional Cu islands and isolated Cu atoms are distinctively characterized by their CO IR peaks. In addition, both disorder-order and order-order transitions are observed for the metal overlayers on the single crystal metal substrates. It was also observed that localized segregation and ordering of mixed Co and S overlayers on a Mo(110) substrate occurs upon annealing.

  8. Mechanically induced atomic disorder and phase transformations. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Limei, D.


    The study shows the possibilities of preparing alloys in various metastable configurations by the simple technique of ball milling. Firstly, chapter 2 gives the description of experimental techniques. In chapter 3, evidence of atomic anti-site disordering in A15-structure superconducting compounds Nb3Sn and Nb3Au during an early stage of milling is demonstrated. Chapter 4 represents the experimental results on the B2-structure magnetic compounds CoGa and CoAl upon mechanical impact. These compounds are well known for their particular type of atomic disorder, namely triple-defect disorder. Various examples of experimental evidence of phase transformations induced by mechanical grinding are presented in chapter 5. Section 5.2 gives an example of amorphization induced by mechanical attrition in the intermetallic compound Ni3Sn. Section 5.3 shows the milling experiment of the intermetallic compound V3 Ga. In section 5.4, for the first time, the observation of a phase transformation to a high-temperature phase with a complex structure will be demonstrated for the intermetallic compound Co3Sn2. In the last chapter, detailed studies on the intermetallic Nb-Au binary compounds for a variety of compositions are presented.

  9. Biochemical remediation of a TNT contaminated soil. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Young, D.G.


    This research presents the first field evidence for the phytoremediation of a TNT contaminated soil by the emersed aquatic plant, Myriophyllum brasiliense. Commonly known as Parrotfeather, this plant features a nitroreductase enzyme capable of promoting the reduction of the nitro groups on TNT to the corresponding amino groups. The proposed reductive pathway takes the TNT through isomers of monoamino and diamino to the final triaminonitrotoluene (TNT) Once in the TAT form and in the presence of oxygen, the final oxidative step quickly yields ring opened products and complete phytoremediation of TNT.

  10. Particle simulation of auroral double layers. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Smith, B.L.


    Externally driven magnetic reconnection has been proposed as a possible mechanism for production of auroral electrons during magnetic substorms. Fluid simulations of magnetic reconnection lead to strong plasma flows towards the increasing magnetic field of the earth. These plasma flows must generate large scale potential drops to preserve global charge neutrality. We have examined currentless injection of plasma along a dipole magnetic field into a bounded region using both analytic techniques and particle simulation.

  11. Diabetic retinopathy. Screening and prevention of blindness. A doctoral thesis. (United States)

    Kristinsson, J K


    Diabetic eye disease is a major cause of blindness in the Western World and remains one of the most serious complications of diabetes mellitus. Retinopathy is the ocular complication of diabetes that most often leads to impaired vision. In recent years laser treatment has been introduced that can significantly decrease the likelihood of blindness in diabetic patients, if the eyes are treated at the appropriate stage of the disease. It remains a public health problem to make sure that each patient is treated at the optimal time in the development of the eye disease. Several types of screening programs have been designed throughout the world to meet this problem. We now report on our active screening program for diabetic eye disease and describe the sight and eye condition of the diabetic patients who have been involved in this program. In 1980, regular eye screening for diabetic retinopathy was initiated at Department of Ophthalmology, Landakot Hospital. The number of diabetic patients seen regularly has increased considerably since then, with 70-80% of type 1 diabetic patients in the country participating in the program in 1990, increasing to over 90% in 1994. About a fifth of type 2 diabetics in the country participated in the program in 1990. The patients have undergone annual eye examinations and fundus photography. Laser treatment is administered for proliferative retinopathy and diabetic macular edema according to the Diabetic Retinopathy Study and Early Treatment Diabetic Retinopathy Study criteria. In 1990, we embarked on a cross-sectional study to evaluate the prevalence of retinopathy and visual impairment of the type 1 and type 2 patients participating in our program. At the time of study, 205 insulin-taking patients, with age at diagnosis of less than 30 years, participated in our screening program. Out of those, retinopathy was present in 106 (52%), patients proliferative retinopathy in 26 (13%) and macular edema in 19 (9%). Visual acuity of 196 patients (96%) was equal or better than 6/12 in their better eye, 6 patients (3%) had 6/18-6/36 in their better eye, and 2 patients (1%) had equal or worse than 6/60 in their better eye, or legally blind. We concluded that the prevalence of retinopathy and visual impairment in type 1 diabetic patients in the country was low compared with other countries. In 1990, out of 245 diabetic patients with Type 2 diabetes, retinopathy was present in 100 patients (41%), proliferative retinopathy had been present in 17 (7%) and 24 (10%) had diabetic macular edema. A total of 224 patients (91%) had visual acuity equal or better than 6/12 in their better eye, 17 patients (7%) with 6/18-6/36 in their better eye, and 4 patients (1.6%) equal or worse than 6/60 in their better eye, or legally blind. We concluded that the prevalence of visual impairment of those type 2 diabetic patients participating in our screening program at the time of study was low compared with population-based studies from other countries. In 1992 we examined ways to make the screening program more efficient by identifying subgroups at low risk for developing eye disease that required treatment and therefore needed less frequent screening. We studied whether diabetic eye disease screening programs could be trimmed by excluding children and examining diabetic patients without retinopathy every other year. We examined all children under the age of 15 at the time of study and went through the files of all patients under age 15 examined from 1980 to 1992 at our diabetic eye screening program. We also followed for two years the type 1 and type 2 diabetic patients found to have no retinopathy in 1990, establishing their retinopathy stage two years later. Our results indicated that diabetic children under the age of 12 do not need regular screening for eye disease. Biannual examinations seemed to suffice in type 1 and 2 diabetic patients without retinopathy. (ABSTRACT TRUNCATED) PMID:9559048

  12. Influence of interfacial tension on nitrogen flooding. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Huijgens, R.J.M.


    The objective of this study was to investigate the influence of interfacial tension (IFT) on the efficiency of developed miscible nitrogen flooding in volatile oil reservoirs. To achieve this objective, we adopted the following approach. First, we designed, constructed, and tested a pendant drop apparatus to accurately measure IFTs at reservoir conditions. The experimental procedure includes video recordings and image processing procedures. We then used the experimental IFTs to evaluate commonly used IFT-prediction methods. Finally, we included the IFT-dependent relative permeability functions in a numerical reservoir simulator and simulated earlier-performed slim tube experiments.

  13. Bat groundwater monitoring system in contaminant studies. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Mines, B.S.


    The purpose of this study is to provide an in-depth, comprehensive study to compare results from the BAT probe and Teflon bailers from nearby monitoring wells. Volatile organic compounds are typically the most difficult contaminants to sample. The research was performed by taking samples within a small radius around monitoring wells at two leaking underground storage tank sites and taking bailer samples from the monitoring wells. BAT sampling will also be performed inside the monitoring wells to ensure basically the same water is being sampled.

  14. The politics of Peacekeeper Rail Garrison. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Van Tassel, A.R.


    In 1985, the Congress capped at 50 the number of Peacekeeper ICBMs that could be deployed in vulnerable Minuteman silos, thereby sending the Reagan administration and the Air Force in search of another basing mode so that 100 of the ton-warhead missiles could be deployed as recommended by the Scowcroft Commission. The result was Peacekeeper rail garrison--a strategic nuclear weapon system that combined the Peacekeeper missile with railroad trains garrisoned at military installations. The missile trains would have dispersed across the nation's railways only during times of 'national need like the Cuban Missile Crisis. This case study examines the politics of that weapon system in order to contribute to the literature regarding weapons acquisition, test a number of propositions suggested by the bureaucratic politics model, and assess the influence of nonbureaucratic forces and actors on Peacekeeper rail garrison's fortunes.

  15. Risk mitigation methodology for solid waste landfills. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Nixon, W.B.


    Several recent models have attempted to simulate or assess the probability and consequences of the leakage of aqueous contaminant leakage from solid waste landfills. These models incorporate common factors, including climatological and geological characteristics. Each model, however, employs a unique approach to the problem, assigns different relative weights to factors, and relies upon extrapolated small-scale experimental data and/or subjective judgment in predicting the full-scale landfill failure mechanisms leading to contaminant migration. As a result, no two models are likely to equally assess a given landfill, and no one model has been validated as a predictor of long-term performance. The United States Air Force maintains a database for characterization of potential hazardous waste sites. Records include more than 500 landfills, providing such information as waste, soil, aquifer, monitoring location data, and the results of sample testing. Through analysis of this information, nearly 300 landfills were assessed to have sufficiently, partially, or inadequately contained hazardous constituents of the wastes placed within them.

  16. Modelling giant radio halos. Doctoral Thesis Award Lecture 2012 (United States)

    Donnert, J. M. F.


    We review models for giant radio halos in clusters of galaxies, with a focus on numerical and theoretical work. After summarising the most important observations of these objects, we present an introduction to the theoretical aspects of hadronic models. We compare these models with observations using simulations and find severe problems for hadronic models. We give a short introduction to reacceleration models and show results from the first simulation of CRe reacceleration in cluster mergers. We find that in-line with previous theoretical work, reacceleration models are able to elegantly explain main observables of giant radio halos.

  7. Cost incentives for doctors

    DEFF Research Database (Denmark)

    Schottmüller, Christoph


    If doctors take the costs of treatment into account when prescribing medication, their objectives differ from their patients' objectives because the patients are insured. This misalignment of interests hampers communication between patient and doctor. Giving cost incentives to doctors increases...... welfare if (i) the doctor's examination technology is sufficiently good or (ii) (marginal) costs of treatment are high enough. If the planner can costlessly choose the extent to which doctors take costs into account, he will opt for less than 100%. Optimal health care systems should implement different...... degrees of cost incentives depending on type of disease and/or doctor....

  12. Doctors' involvement in torture

    DEFF Research Database (Denmark)

    Sonntag, Jesper


    Doctors from both non-democratic and democratic countries are involved in torture. The majority of doctors involved in torture are doctors at risk. Doctors at risk might compromise their ethical duty towards patients for the following possible reasons: individual factors (such as career, economic...... or ideological reasons), threats, orders from a higher ranking officer, political initiatives, working in atrocity-producing situations or dual loyalty. In dual loyalty conflicts, factors that might compromise doctors' ethical obligations towards detainees/patients are: ideological totalitarianism......, moral disengagement, victim blame, patriotism, individual factors or threats. Another important reason why doctors are involved in torture is that not all doctors are trained in addressing human rights issues of detainees. Torture survivors report that they have experienced doctors' involvement in...

  2. Doctors in Balzac's work. (United States)

    Moulin, Thierry


    Balzac wrote his novels during a time of great literary and scientific change. Romanticism gave way to the school of realism, of which Balzac could be considered the founder. It was via realism, where both the positive and negative aspects of life were depicted, that doctors naturally gained a much more active role in novels. In conjunction with this was the development of science and medicine, which fascinated Balzac, also leading to the significant and prevalent role of doctors in his works. His fascination with the sciences led to him to gain many acquaintances and much knowledge in the medical domain, especially in neuropsychiatry and physiology. His fictional doctors, such as Desplein and Bianchon, thus demonstrate considerable knowledge of pathology, physiology, and neuropsychiatry. The doctors in Balzac's novels can be grouped into four categories: provincial doctors, Parisian doctors, country doctors, and military doctors. They were most often fictitious representations of real individuals (e.g. Guillaume Dupuytren), and often symbolize schools of thought which were in vogue at the time. In addition to the accurate scientific depiction of doctors, it must be noted that his doctors not only played an active role in clinically assessing their patients, but also had a sociological role in assessing society; it is through his doctors that Balzac gave his opinion of the world in which he lived.

  11. Should junior doctors strike? (United States)

    Toynbee, Mark; Al-Diwani, Adam Aj; Clacey, Joe; Broome, Matthew R


    An impasse in negotiations between the Department of Health (DoH) and the British Medical Association in November this year led to an overwhelming vote for industrial action (IA) by junior doctors. At the time of writing, a last minute concession by DoH led to a deferment of IA to allow further negotiations mediated by the Advisory, Conciliation and Arbitration Service. However, IA by junior doctors remains a possibility if these negotiations stall again. Would the proposed action be ethically justifiable? Furthermore, is IA by doctors ever ethically defendable? Building on previous work, we explore important ethical considerations for doctors considering IA. The primary moral objection to doctors striking is often claimed to be risk of harm to patients. Other common arguments against IA by doctors include breaching their vocational responsibilities and possible damage to their relationship with patients and the public in general. These positions are in turn countered by claims of a greater long-term good and the legal and moral rights of employees to strike. Absolute restrictions appear to be hard to justify in the modern context, as does an unrestricted right to IA. We review these arguments, find that some common moral objections to doctors striking may be less relevant to the current situation, that a stronger contemporary objection to IA might be from a position of social justice and suggest criteria for ethically permissible doctor IA.

  13. Doctors as managers: poachers turned gamekeepers? (United States)

    Hunter, D J


    Doctors in health care systems of different types are coming under increasing pressure to take on active roles in management. Mounting concern among governments over the escalating costs of health care, coupled with a desire to improve the quality of care and render services more responsive to user preferences has resulted in management being viewed as offering an effective means of tackling these issues. Until recently, the favoured strategy was to strengthen management in order to curb doctors' discretionary decision-making. There is now a shift towards creating managers out of doctors with all that this implies for the future shape of health services. There are also issues about the training and development required for a management role, the stratification of roles within the medical profession, and the future status of lay, or non-medical managers. The paper reviews the debate about doctors and managers and their distinctive value bases. It suggests that doctors can be involved in management as managers at two levels--meso and micro--and considers the issues raised at each level. The paper presents an analysis of the wider context in which the debate about doctors as managers is taking place. The main thesis put forward is that far from managers incorporating doctors, the end result may prove to be the other way round with 'provider capture' of the management agenda in health services a distinct possibility. In contrast to managers, doctors retain enormous public respect and support. As long as it is so doctors will remain powerful stakeholders in defining and controlling the shape and range of health services available. Their active involvement in management could lead to a strengthening of their position. It is argued that, paradoxically, this could make it more difficult for governments to challenge doctors' work practices. Medicine's traditional preoccupations and its resilience to change are likely to remain as strong as ever thereby disappointing

  14. Gene expression analysis of neuronal precursors from adult mouse brain and differential screen for neural stem cell markers


    Pennartz, Sandra


    In the adult mouse brain, neuronal precursor cells continuously emanate from neural stem cells (NSC) in the subventricular zone (SVZ) and migrate into the olfactory bulb (OB) where they differentiate to serve as replenishment for GABAergic interneurons. During the migration process, PSA-NCAM (Polysialic acid-Neural cell adhesion molecule) specifically marks the neuronal precursors (PSA+ cells). This phenomenon was exploited in the framework of this doctoral thesis to isolate a homogeneous cel...

  15. [Doctors' alcohol problems]. (United States)

    Florkowski, Antoni; Gruszczyński, Wojciech; Gałecki, Piotr; Szubert, Sławomir; Klus, Marek; Zboralski, Krzysztof


    An overusing and an addiction to alcoholic drinks are important problems in a medical society. The studies made in the United States had documented that about 8-12% doctors were addicted to alcohol. In many cases the doctors are able to keep their problem as a secret and their activity is satisfied up to the moment when a decrease is noticed. Some factors--such as a high level of stress--predispose doctors to alcoholic problems especially surgeons. Alcohol problems should be identified as early as possible, and therapy ought to be given as well. There is no reason to hide the problem. PMID:19025048

  6. Women Doctors in 1914

    Institute of Scientific and Technical Information of China (English)


    THE five women shown here are doctors. Eighty-four years ago, they sat for this photographic portrait. The photo depicts the tasteful combination of East and West. While the photographic studio was decorated in the European style, the women doctors were dressed in traditional Chinese fashion with their hair coiled in Japanese style. We can also see that though the ladies were in vogue for their time, they still displayed shyness facing a male photographer, as most can be observed shifting their eyesight away from the lens.

    Full Text Available This article probes the implications of neo-conservative public education policies for the future of the academic profession through a detailed examination of critical issues shaping contemporary doctoral education in U.S. and Canadian universities. Institutional and social factors such as financial retrenchment, declining support for affirmative action, downward economic mobility, a weak academic labor market for tenure-track faculty, professional ethics in graduate education, and backlash against women's progress form the backdrop for analysis of the author's survey of current doctoral students' opinions about funding, support, the job market, and quality of learning experiences.

  8. Specific heat in high magnetic fields. A study of the heavy-fermion systems U(Pt,Pd)3 and CeRu2Si2 and the high-Tc superconductors ReBa2Cu2O7. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    van der Meulen, H.P.


    The subject of the thesis is the study of the low-temperature electronic behavior of two classes of materials: the high-T(c) superconductor YBa2Cu3O7 with rare-earth substitutions for Y, and the heavy-fermion compounds U(Pt,Pd)3 and CeRu2Si2. The thesis is organized as follows: In chapter 2, the experimental technique for performing specific-heat measurements in high static magnetic fields are discussed. In addition, a paper on new possibilities of magnetic ripple shielding for specific heat measurements in hybrid magnets is presented. Chapter 3 is devoted to the high-T(c) superconductors of the series REBa2Cu3O7. In chapter 4, the low-temperature specific heat of REBa2Cu3O7, as studied in magnetic fields up to 5 T, is presented. The authors discuss measurements from which information about the crystal-field level schemes of the rare-earth ions can be derived. Chapter 5 is devoted to specific-heat studies in the heavy-fermion superconductor UPt3, and in the Pd-substituted U(Pt1-xPdx)3 compounds, with x=0.05 and 0.10. Chapter 6 describes the field suppression of the heavy-fermion state in CeRu2Si2.

  17. Characterization of deep-marine clastic sediments from foreland basins: Outcrop-derived concepts for exploration, production and reservoir modelling. Doctoral thesis; Karakterizering van diep-mariene klastische sedimenten uit voorland bekkens: Aan ontsluitingen ontleende concepten voor exploratie, produktie en reservoir modellering

    Schuppers, J.D.


    Deep-marine clastic sediments are the host for many prolific hydrocarbon reservoirs. The sandbodies that form these reservoirs show a wide variety in shape, spatial arrangement, and internal structure. The outcrops studied for this thesis pertain to the fill of circum-mediterranean foreland basins in Spain and Greece. The outcrops have allowed the description of the multiscale anatomy of sandbodies that cover a wide range of depositional settings. The descriptions are focused on those features that are most likely to influence the flow of fluids through analogous reservoirs of similar construction. Extensive use was made of photomosaics to outline the large-scale geometries and stacking modes of the sandbodies. The sediments studied form the basis for seven `reservoir models` that are both descriptive and conceptual.

  18. Reinventing The Doctor

    Full Text Available There has been a seismic shift in the lives of people because of technology. People are far better informed than they were in the 1980s and 1990s. Much of this information is available through the media but even more is available and archived on the internet. The forces pushing the internet into health and health care are strong and unstoppable, ensuring that the internet and the choices it offers must be part of the design of our future health care system. We are no longer content to wait in queues as we live at a faster pace than earlier generations — we don’t not have time to wait for appointments months, weeks or even days in advance. The internet offers the prospect of online consultations in the comfort of your own home. The physical examination will change as new devices are developed to allow the necessary sounds and signals emitted by our malfunctioning bodies to be recorded, interpreted and captured at a remote location. Meanwhile, for those who prefer to see a health care practitioner in person the options to consult practitioners other than doctors who can advise on our health is expanding. The reality is we can’t afford to train or pay for all the doctors we need under the current “doctor-knows-best” system of health care. Patients no longer believe the rhetoric and are already voting with their feet. Pharmacists, nurses and other allied health professionals are beginning to play a much greater role in offering relief from symptoms and monitoring of chronic diseases. Of course, the doctor of the future will still need to offer face-to-face consultations to some people most of the time or most people some of the time. The social role doctors play will continue to be important as humans will always need other humans to personally respond to their distress. As doctors reinvent themselves, the internet and the value of time with patients will be the driving forces that move us into a more sustainable future in health care.

  19. Scientometric Study of Doctoral Theses of the Physical Research Laboratory (United States)

    Anilkumar, N.


    This paper presents the results of a study of bibliographies compiled from theses submitted in the period 2001-2005. The bibliographies have been studied to find out how research carried out at PRL is being used by the doctoral students. Resources are categorized by type of resource — book, journal article, proceedings, doctoral thesis, etc., to understand the usage of content procured by the library. The period of the study, 2001-2005, has been chosen because technology is changing so fast and so are the formats of scholarly communications. For the sake of convenience, only the "e-journals period" is considered for the sample.

  2. Radon house doctor

    International Nuclear Information System (INIS)

    The term house doctor may be generalized to include persons skilled in the use of instruments and procedures necessary to identify, diagnose, and correct indoor air quality problems as well as energy, infiltration, and structural problems in houses. A radon house doctor would then be a specialist in radon house problems. Valuable experience in the skills necessary to be developed by radon house doctors has recently been gained in an extensive radon monitoring and mitigation program in upstate New York sponsored by Niagara Mohawk Power Corporation and the New York State Energy Research and Development Authority. These skills, to be described in detail in this paper, include: (i) the use of appropriate instruments, (ii) the evaluation of the symptoms of a radon-sick house, (iii) the diagnostic procedures required to characterize radon sources in houses, (iv) the prescription procedures needed to specify treatment of the problem, (v) the supervision of the implementation of the treatment program, (vi) the check-up procedures required to insure the house cured of radon problems. 31 references, 3 tables

  6. Brain Drain Controversy


    Borta, Oxana


    This thesis focuses on the widely acknowledged so-called brain drain controversy. More concretely on developments in the traditional brain drain literature towards a new shift, claiming the brain gain effect, as an alternative to the brain drain effect, that emigration may bring to a source country. The research investigates not only the obvious direct loss effects – the so called brain drain – but also the possibility of more subtle indirect beneficial effects.

  7. [Doctor's behavior in disasters]. (United States)

    Wälchli, Peter


    When facing a disaster outside of hospitals, physicians have to work in unfamiliar surroundings. Self-protection is the first priority: be aware of possible dangers of traffic, explosions, electricity, structural collapse and toxic gas. Arriving first, one should safe the scene of accident (e.g. breakdown triagle, turn off electricity) and try to get a general idea of what has occured. After that, call the rescue services (in Switzerland dial 144). Only once this ist done, should one begin treating patients. If the rescue services are at scene, look for the commander, usually fitted out with a warning west "Einsatzleiter" ("chef d'intervention" in the french speaking part of Switzerland). Introduce yourself (name, profession, skills and material). In disasters, fields other than medicine are often more important. Nevertheless, doctors can help with logical thinking, strong and agile hands and attentive listening. One should only do the tasks assigned. In situations with mass casualities, morbidity and mortality can be reduced by special measures. The most important for physicians is the Triage. Triage is the sorting of patients based on their need for treatment and transport with the available resources. Triage ist usually run by the most experienced doctor. PMID:18399181

  8. Female physicist doctoral experiences (United States)

    Dabney, Katherine P.; Tai, Robert H.


    The underrepresentation of women in physics doctorate programs and in tenured academic positions indicates a need to evaluate what may influence their career choice and persistence. This qualitative paper examines eleven females in physics doctoral programs and professional science positions in order to provide a more thorough understanding of why and how women make career choices based on aspects both inside and outside of school and their subsequent interaction. Results indicate that female physicists experience conflict in achieving balance within their graduate school experiences and personal lives and that this then influences their view of their future careers and possible career choices. Female physicists report both early and long-term support outside of school by family, and later departmental support, as being essential to their persistence within the field. A greater focus on informal and out-of-school science activities for females, especially those that involve family members, early in life may help influence their entrance into a physics career later in life. Departmental support, through advisers, mentors, peers, and women’s support groups, with a focus on work-life balance can help females to complete graduate school and persist into an academic career.

  9. Doctors writing outside the square. (United States)

    Full Text Available "Ring…ring…" bleated a mobile phone, waking Lha mo, a student in the Tibetan Department at a well-known nationalities university. She raised her head languidly and looked around the dorm room. Her roommates were applying various cosmetics and lotions to their faces, getting ready for class. The warm sun heated her bed. She slowly turned her head to the right and gazed at a small picture of a young Chinese movie star pasted on the wall by her bed. He was wearing a shirt that exposed his skin, which seemed as white as flour smeared on a cutting board beneath a ball of dough. Nearby was a panda doll wearing a suit of red clothes that made it resemble a sleeping guard. She was suddenly overwhelmed by nostalgia. Lha mo came from an area where Tibetan was rarely taught. Sometimes she hated herself for being Tibetan. Lha mo would soon leave school and was required to write a thesis. Because her written Tibetan was very poor, she resolved to use Chinese, and spent two weeks writing a few lines in her notebook. What she wrote had many grammar mistakes and she quickly and angrily ripped the pages into pieces. She agonized about her situation and didn't know what to do. Then she heard the good news that a thesis could be purchased in Room 304, East Second Street. The problem was that it cost 2,000 yuan, which was far too expensive for her. She only received 1,000 yuan a month from her family, half of which was for food and the other half went to meet the cost of clothes and other expenses. She just didn't have the money to buy the thesis. ...

  2. Professionalism for future humanistic doctors

    Directory of Open Access Journals (Sweden)



    Full Text Available Dear editor Clinical environments encounter is an important part of studying medicine (1. Patient contact as an integral part of medical education occurs in various formats in the clinical settings (2, 3. During clinical training, medical students may experience high levels of stress, and some may not deal with it well. The abruptness of students’ transition to the clinical setting generated positive and negative emotions. Due to being a novice, they did not receive adequate training on how to get emotionally prepared for meeting seriously ill people. In such circumstances, the shortage of training will have predictably crucial consequences. Early clinical contact has been suggested to reduce these stresses and help the students adapt effectively to changes in the hospital climate (2. Patient contact creates an environment where each student appreciates cultural diversity and reinforces the development of clinical professional interpersonal skills through social, emotional and cognitive experiences (4, 5. It encourages validating of the relationship between patients and doctors and allows students to experience a more personal relationship with patients and nurture the ability to empathize with them, providing considerable benefits for trainees and patients. In this way, the social emotions that students experience when empathizing with a patient represent a uniquely human achievement. By internalizing their subjective interpretations of patient’s beliefs and feelings, the student’s body, brain and mind come together to produce cognition and emotion . They construct culturally relevant knowledge and make decisions about how to act and think about the patient’s problems as if they were their own. On the other hand, patient interaction in undergraduate education offers students a valuable early insight into the day-to-day role of a doctor and the patients’ perspective on specific conditions. Early experience provides a greater knowledge

  3. Hospital structure and technical efficiency in the production of nuclear medicine. Doctoral thesis

    International Nuclear Information System (INIS)

    The relationship of hospital structure to production efficiency is explored. The hospital subindustry on which this research centers is nuclear medicine. The hypotheses generated were that technical efficiency is reduced by increased competitive intensity, by a lack of profit incentive, by a broader service range, and by in-house training of technical personnel. Most data employed in the study were gathered from the American College of Radiology and the Energy Research and Development Administration Census of Nuclear Medicine. More specific information came from questionnaires sent to 2,050 short-term general hospitals known to have a nuclear medicine facility. Of the responses 1,362 were usable for the study. A major study finding was that over half of the variations observed in technical efficiency were attributable to the structural elements being studied. The research indicated that competition for staff physicians has a role in reducing technical efficiency; that the output effect of in-house manpower training was relatively unimportant; and that profit incentives do have a significant impact. It is suggested that increased technical efficiency could be achieved through reduced competitive intensity, stronger profit orientation, and reduced service range. A bibliography is included

  5. Calculational study on neutron kinetics and thermodynamics of a gaseous core fission reactor. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Kuijper, J.C.


    The aim of the authors' work was to investigate the static and dynamic properties of a GCFR with oscillating (moving) fuel gas. A simplified schematic diagram of such a GCFR, similar to the concept of Kistemaker (Kis78a), is shown. It consists of a graphite cylinder of, say, 2 m diameter and 10 m length, filled with a mixture of uranium and carbon fluorides (UCF) at high temperature in ionized state, in chemical and thermodynamical equilibrium with the graphite cylinder wall (Kis78a, Kis86, Kle87). The cylindrical gas space is divided into an active 'core' region, surrounded by an effective (thick) neutron reflector, and a so-called 'expander' region, surrounded by a much less effective (thinner or with neutron poison) neutron reflector. In operation, part of the fuel gas oscillates back and forth between core and expander region. The investigation requires the study of neutron statics, neutron kinetics, reactor gas thermodynamics and gas dynamics, resulting in a combined calculational model, containing these aspects. In order to achieve this the authors followed a step-by-step approach.

  7. Detection and characterization of high frequency and high wavenumber solar oscillations. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Fernandes, D.N.


    Doppler shift measurements of the Na D1 absorption line have revealed solar oscillations in a new regime of frequency and wavenumber. Oscillations of vertical velocities in the temperature minimum and low chromosphere of the Sun are observed with frequencies ranging up to 9.5 mHz. There is no evidence for chromospheric modes of 3 minute period. This indicates that the chromosphere does not form a good cavity for acoustic waves. The fundamental-modes appear with wavenumbers up to 5.57/Mn (equivalent spherical harmonic degree, 3877). The frequencies lie below the predicted values at wavenumbers above 1/Mn. The values are in agreement with previous measurements that exist for wavenumbers up to 2.67/Mn. Spatial maps of velocity power show that high wavenumber oscillations are suppressed in active regions. The shape of the power depression indicates that wave motion is affected in the layer of atmosphere where the measurement is made. The f-modes are suppressed in the same way as p-modes, indicating that the mechanism for wave suppression affects velocity fluctuations. Mode frequencies are not affected by the magnetic fields by more than 50 microHz, the precision of the measurement. Fluctuations in solar activity are of interest to researchers in communications and environmental/atmospheric science.

  8. Spectroscopic study of neon Z-pinch plasma for sodium-neon photopumping experiments. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Welch, B.L.


    Spectroscopic measurements were made of neon Z-pinch plasmas to establish conditions appropriate for sodium-neon photopumping. Emissions of soft X-rays, extreme ultraviolet (XUV), and near ultraviolet (NUV) were measured. Plasma electron temperatures and densities were determined by comparing measurements with steady-state and time-dependent atomic-physics models. Dependences of plasma emissions on the magnitude and risetime of the current and on the initial mass loading were investigated. Peak currents of 120 to 300 kA and 1-micronsec to 50-ns risetime were used to implode a 1-cm diameter neon gas puff. Mass loadings ranging from 1.2 to 3.6 microgram/cm were varied by adjusting the gas-puff pressure. Adjustments of the current, current risetime, and mass loading can be used to produce an appropriate neon plasma for sodium-neon photopumping.

  10. Three-dimensional reactor dynamics code for VVER type nuclear reactors. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Kyrki-Rajamaeki, R.


    A three-dimensional reactor dynamics computer code HEXTRAN has been developed, thoroughly validated, and extensively applied for transient and accident analyses of VVER type nuclear reactors. HEXTRAN models accurately the VVER core with hexagonal fuel assemblies. The code uses advanced mathematical models in spatial and time discretization of neutronics, heat transfer and two-phase flow hydraulics. The dynamic coupling with the thermal hydraulic system code SMABRE allows also the modelling of cooling circuits. Best-estimate or conservative analyses can be performed for different accidents, e.g., RIA, ATWS or local boron dilutions. The usefulness of the three-dimensionality is shown particularly when there are asymmetric or thermal hydraulic disurbances in the core or cooling circuits.

  11. Observing and modelling f-region ionospheric dynamics using the (OII) 7320a emission. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Carr, S.S.


    Limb-scan observations of Doppler line profiles from the (OII) lambda 7320A emission at F-Region altitudes, made with the Fabry-Perot interferometer (FPI) on the Dynamics Explorer-2 (DE-2) spacecraft, have been analyzed to provide measurements of the meridional component of the ion convection velocity along the instrument line-of-sight. The DE-2 results presented here demonstrate the first spaceborne use of the remote-sensing Doppler techniques for measurements of ionospheric convection. The FPI meridional ion drift measurements have been compared with nearly simultaneous in situ ion drift measurements from the Retarding Potential Analyzer (RPA) on DE 2. Once allowance is made for the temporal lag between the in situ and remote measurements, the results from the two techniques are found to be in good agreement, within specified experimental errors, giving confidence in the FPI measurements.

  12. Recollimation shocks in the relativistic outflows of active galactic nuclei. Doctoral Thesis Award Lecture 2014 (United States)

    Fromm, C. M.


    We analysed the single-dish radio light curves of the blazar CTA 102 during its major flare around April 2006. The modelling of these data revealed a possible travelling shock-recollimation shock interaction during the flare. To verify this hypothesis, we used multi-epoch and multi-frequency very-long baseline interferometry (VLBI) observations and performed a detailed kinematic and spectral analysis. The results confirmed the hypothesis of a shock-shock interaction causing the 2006 radio flare and provided indications for additional recollimation shocks farther downstream.

  13. Three region analysis of a bounded plasma using particle in cell and fluid techniques. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Nichols, D.F.


    A detailed collisionless sheath theory and a three-region collisional model of a bounded plasma are presented, and the suitability of the collisional model for analysis of ignited mode thermionic converters is investigated. The sheath theory extends previous analyses to regimes in which the sheath potential and electron temperatures are comparable in magnitude. In all operating regimes typical of a ignited mode thermionic converter, the predicted sheaths extend several mean-free paths. The apparent collisionality of the sheaths prompted development of a collisional, three-region model of the converter plasma. By interfacing Particle-in-Cell regions (for the sheaths) and fluid regions (for the bulk of the plasma), a time-dependent, wall-to-wall model of the plasma in the inter-electrode space is created. The components of the model are tested and validated against analytic solutions and against one another, then applied to the analysis of an ignited mode thermionic converter. Under ignited mode operating conditions, the electron velocity distribution at the plasma/sheath boundary is found to be inconsistent with that assumed in the model development, and the calculation diverges. The observed distribution is analyzed and a new basis set of distribution functions is suggested that should permit application of the hybrid model to ignited mode thermionic converters.

  14. Process alternatives for the fermentation of glucose/xylose mixtures by Pichia stipitis. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Grootjen, D.R.J.


    Technical substrates for the fermentative production of ethanol often contain hexose and pentose sugars. For an optimal ethanol yield a complete conversion of all sugars in such a substrate is desired. Pichia stipitis, a yeast that can convert hexose as well as pentose sugars, shows the sequential use of substrate. Therefore pentose will not be converted when the hexose concentration is too high. A complete conversion to ethanol of a mixed substrate in a normal continuous culture will be difficult. Furthermore P. stipitis needs oxygen for growth. However too much oxygen will shift the metabolism from ethanol to biomass production. The aim of the project was to find ways to convert a mixed substrate, which contains hexose and pentose sugars, using P. stipitis to ethanol in a continuous process with a high ethanol yield and production rate. For this purpose a model substrate that contained glucose (40 g/l;) and xylose (10 g/l) was used.

  15. Composite-system-stability-methods applied to advanced shipboard electric-power systems. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Amy, J.V.


    Large increases in the complexity of shipboard electric loads as well as development of electric drive, integrated electric drive and pulsed power systems make manifest the present and future importance of naval electric power systems. The most crucial attribute of these systems is their ability to fulfill their function in the presence of large-signal perturbations. Fundamental differences between shipboard and commercial electric power systems make all but the most general nonlinear, large-signal stability analyses inappropriate for the design and assessment of naval electric power systems. The tightly coupled and compact nature of shipboard systems are best accommodated by composite system stability analyses. Composite system methods, based upon Lyapunov's direct method, require that each component's stability be represented by a Lyapunov function. A new Lyapunov function which is based upon co-energy is developed for 3-phase synchronous machines. This use of co-energy is generalizable to all electromechanical energy conversion devices. The co-energy-based Lyapunov function is implemented as a stability organ which generates waveforms at information terminals of a device object in the object oriented simulation environment of WAVESIM. Single generator simulation results are used to acquire a measure of the over sufficiency of the co-energy-based Lyapunov function.

  16. 2010 Award for Outstanding Doctoral Thesis Research in Biological Physics Talk: How the Genome Folds (United States)

    Lieberman-Aiden, Erez


    I describe Hi-C, a novel technology for probing the three-dimensional architecture of whole genomes by coupling proximity-based ligation with massively parallel sequencing. Working with collaborators at the Broad Institute and UMass Medical School, we used Hi-C to construct spatial proximity maps of the human genome at a resolution of 1Mb. These maps confirm the presence of chromosome territories and the spatial proximity of small, gene-rich chromosomes. We identified an additional level of genome organization that is characterized by the spatial segregation of open and closed chromatin to form two genome-wide compartments. At the megabase scale, the chromatin conformation is consistent with a fractal globule, a knot-free conformation that enables maximally dense packing while preserving the ability to easily fold and unfold any genomic locus. The fractal globule is distinct from the more commonly used globular equilibrium model. Our results demonstrate the power of Hi-C to map the dynamic conformations of whole genomes.

  19. Forest machine contractors in Swedish industrial forestry: Significance and conditions during 1986-1993. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Liden, E.


    The aim of this review was to come to a general understanding of the phenomenon of contracting in forestry as an occupation and a life-style. This has been accomplished by studies on machine ownership, working conditions, and attrition from forestry, using quantitative methods in combination with qualitative ones, during the period 1986 to 1993. The studies pertained to industrial forestry in Sweden. In 1992/93 70% of all machines used in industrial forestry in Sweden were owned by contractors. Together these machines harvested 59% of the total quantity during the 1992/93 harvesting season. Three categories of contractors were recognized; the single contractor, the partner contractor, and the contractor with employees. It was concluded that being a contractor is more a life-style than an occupation. Very often the whole family is involved in the business. The contractors` willingness to work hard and to do a good job is an asset for forestry.

  20. Adolescent depression. Epidemiology, nosology, life stress and social network. Minireview based on a doctoral thesis. (United States)

    Olsson, G


    The study engaged a total population of 16-17-year-old urban high-school students and 2300 (93%) were screened for depression and previous suicide attempts. Adolescents with high depression scores in self-evaluation (12.3%) or reporting previous suicide attempts (2.4%) were diagnostically interviewed together with one control for each, matched for gender and educational program. After the interview self-ratings were completed regarding social network, family climate, and life events. Major depression was prevalent during the last year in 5.8% and during life time in 11.4%, 4 girls for every boy. A depression with remaining symptoms for a year or more was the most common type. Dysthymia without major depressive episodes was diagnosed in 1.1%, two girls for every boy. Short hypomanic episodes had been experienced by 13.2% of those with major depressive disorder. Anxiety disorder was comorbid to depression in one half and conduct disorder in one forth of the depressed adolescents. Alcohol was abused by 6.5% and used regularly by another 12%. Other drugs were used by 6.5% of depressed adolescents and not at all by controls. The depressed used tobacco twice as frequently as non-depressed. Social network and family climate were compared within the originally matched pairs. Adolescents with long-lasting depressions had a smaller and unsatisfying social network. They also had experienced many stressful life events related to family adversities, while those with shorter depressive episodes had stress related to the peer group. Depressed adolescents with comorbid conduct disorder reported insufficient support from the close network and a more negative family climate. PMID:9923068

  1. Gravitational and centrifugal oil-water separators with plate pack internals. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Plat, R.


    After some stages of treatment, most production water and other oily waste water is discharged into the sea or onto other surface water. To protect the environment, the total amount of oil discharged must be kept to a minimum. Legislation with regard to the discharge of oil into the sea is being pursued in an international context. One of these is the Paris Convention, covering regulations for discharges from both offshore and onshore operations in and around the North Sea; a limit of 40 ppm monthly average has been agreed. Concerning gravity and centrifugal separators, theoretical studies have been carried out with respect to oil-droplet shape, forces acting on oil droplets and interactions of oil droplets with oil-water interfaces. For these types of separators, oil-droplet diameters within the critical range may be assumed to be rigid spheres; Stokes' law is valid. A generally applicable separation efficiency function has been derived analytically, which is valid for gravity separators as well as centrifuges. Computer simulations and laboratory experiments support the predictions of this function. Gravity plate separators are among the most frequently applied separator types in the oil-industry. The gravity plate separator is relatively cheap compared to other types of separators, but it is heavy and bulky and cannot always reach the target effluent oil concentration of 40 ppm. The centrifuge is one of the best separators. It can meet the Paris Convention requirements and gives good performance in relation to required deck space and weight. The main disadvantage of the centrifuge is its high cost.

  3. Somatostatin receptor expression and biological functions in endocrine pancreatic cells: review based on a doctoral thesis. (United States)

    Ludvigsen, Eva


    Type 1 diabetes is resulting from the selective destruction of insulin-producing betacells within the pancreatic islets. Somatostatin acts as an inhibitor of hormone secretion through specific receptors (sst1-5). All ssts were expressed in normal rat and mouse pancreatic islets, although the expression intensity and the co-expression pattern varied between ssts as well as between species. This may reflect a difference in response to somatostatin in islet cells of the two species. The Non-Obese Diabetic (NOD) mouse model is an experimental model of type 1 diabetes, with insulitis accompanied by spontaneous hyperglycaemia. Pancreatic specimens from NOD mice at different age and stage of disease were stained for ssts. The islet cells of diabetic NOD mice showed increased islet expression of sst2-5 compared to normoglycemic NOD mice. The increase in sst2-5 expression in the islets cells may suggest either a contributing factor in the process leading to diabetes, or a defense response against ongoing beta-cell destruction. Somatostatin analogues were tested on a human endocrine pancreatic tumour cell line and cultured pancreatic islets. Somatostatin analogues had an effect on cAMP accumulation, chromogranin A secretion and MAP kinase activity in the cell line. Treatment of rat pancreatic islets with somatostatin analogues with selective receptor affinity was not sufficient to induce an inhibition of insulin and glucagon secretion. However, a combination of selective analogues or non-selective analogues via costimulation of receptors can cause inhibition of hormone production. For insulin and glucagon, combinations of sst2 + sst5 and sst1 + sst2, respectively, showed a biological effect. In summary, knowledge of islet cell ssts expression and the effect of somatostatin analogues with high affinity to ssts may be valuable in the future attempts to influence beta-cell function in type 1 diabetes mellitus, since down-regulation of beta-cell function may promote survival of these cells during the autoimmune attack.

  4. Solid-fuel flame spread and mass burning in turbulent flow. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Zhou, L.


    An experimental study has been carried out to investigate the controlling mechanisms of solid fuel flame spread and mass burning in turbulent flows. The effects of flow velocity, turbulence intensity and buoyancy on concurrent and opposed flame spread rate and surface regression rate have been examined in both floor and ceiling configurations. It is found that for opposed flows, the flame spread rate of thermally thick PMMA sheet increases initially with the flow velocity, reaches a peak value and then decreases as the flow velocity increases further. The flow turbulence effect is to increase the flame spread rate initially and then decreases it at higher turbulence intensity. The flame spread rate of thermally thin paper sheet in an opposed flow decreases monotonically with the flow velocity and turbulence intensity. The flow turbulence also has a significant effect on the flame extinction conditions, resulting in a smaller extinction velocity for larger flow turbulence intensity. For concurrent flow flame spread, it is found that the flow turbulence decreases the flame spread rate for both floor and ceiling geometries, mainly as a result of the flame length shortening at high turbulence intensity. It is also found that flow velocity intensifies the spread of the flame.

  5. AGN jets under the microscope: A divide? Doctoral Thesis Award Lecture 2011 (United States)

    Karouzos, M.; Britzen, S.; Witzel, A.; Zensus, A. J.; Eckart, A.


    A new paradigm for active galactic jet kinematics has emerged through detailed investigations of BL Lac objects using very long baseline radio interferometry. In this new scheme, most, if not all, jet components appear to remain stationary with respect to the core but show significant non-radial motions. This paper presents results from our kinematic investigation of the jets of a statistically complete sample of radio-loud flat-spectrum active galaxies, focusing on the comparison between the jet kinematic properties of BL Lacs and flat-spectrum radio-quasars. It is shown that there is a statistically significant difference between the kinematics of the two AGN classes, with BL Lacs showing more bent jets, that are wider and show slower movement along the jet axis, compared to flat-spectrum radio-quasars. This is interpreted as evidence for helically structured jets.

  6. Study of enzymatic reactors with microencapsulated lipase. Doctoral thesis. Estudo de reactores enzimaticos com lipase microencapsulada

    Energy Technology Data Exchange (ETDEWEB)

    de Franca Teixeira dos Prazeres, D.M.


    The work reports the development of a membrane reactor for the hydrolysis of triglycerides catalyzed by lipase B from Chromobacterium viscosum in AOT/isooctane reversed miceller system. In a preliminary phase the potential of the organic system was evaluated with comparative studies on the activity and stability of lipase B in aqueous media (emulsion) and in the alternative miceller media. A tubular ceramic membrane reactor with recirculation was selected for the olive oil hydrolysis in a reversed miceller system. The influence of the hydration degree, recirculation rate, AOT, olive oil and lipase concentration in the operation of the reactor were investigated in a batch mode. The hydration degree was identified as a critical parameter due to its influence in the separation process and in the kinetics of the reaction.

  7. Fast and parallel spectral transform algorithms for global shallow water models. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Jakob, R.


    The dissertation examines spectral transform algorithms for the solution of the shallow water equations on the sphere and studies their implementation and performance on shared memory vector multiprocessors. Beginning with the standard spectral transform algorithm in vorticity divergence form and its implementation in the Fortran based parallel programming language Force, two modifications are researched. First, the transforms and matrices associated with the meridional derivatives of the associated Legendre functions are replaced by corresponding operations with the spherical harmonic coefficients. Second, based on the fast Fourier transform and the fast multipole method, a lower complexity algorithm is derived that uses fast transformations between Legendre and interior Fourier nodes, fast surface spherical truncation and a fast spherical Helmholz solver. Because the global shallow water equations are similar to the horizontal dynamical component of general circulation models, the results can be applied to spectral transform numerical weather prediction and climate models. In general, the derived algorithms may speed up the solution of time dependent partial differential equations in spherical geometry.

  8. Cadmium: A toxin and a nutrient for marine phytoplankton. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Lee, J.G.


    Although cadmium is known to be very toxic, it exhibits nutrient-like vertical concentration profiles in the open ocean. Cadmium enhances the growth of the marine diatom Thalassiosira weissflogii, a chlorophyte and some prymnesiophytes at inorganic zinc and cadmium concentrations typical of surface seawater. Detailed studies of T. weissflogii show that cadmium is also regulated like a nutrient over a wide range of external inorganic cadmium (5-500pM) and inorganic zinc (2-16pM) concentrations. The cellular cadmium concentration is maintained at relatively constant levels both through uptake and, at high inorganic cadmium concentrations (5nM), export of cadmium, most likely complexed to the metal-binding polypeptide phytochelatin. Cadmium may play an essential role in carbon uptake under conditions of zinc limitation. The same low level of inorganic cadmium that enhances the growth of T. weissflogii restores the activity of carbonic anhydrase, thought to be the key enzyme limiting growth at low zinc. Cadmium coelutes with a least one of the multiple isoforms of carbonic anhydrase produced by T. weissfiogii and covaries with activity of this isoform. The substitution of cadmium for zinc in carbonic anhydrase links the geochemical cycle of cadmium to those of zinc and carbon.

  9. Single specimen fracture toughness determination procedure using instrumented impact test. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Rintamaa, R.


    The focus of the work is aimed at two scientific issues. The primary emphasis is directed to develop a method which enables the detection of ductile crack initiation, and hence the energy-based fracture toughness, by applying an optical crack opening displacement (COD) measuring device. It is claimed that the Double Displacement Ratio (DDR), i.e., the ratio of crack opening displacement vs. specimen displacement indicates the onset of ductile crack growth initiation in a way which is easy and reliable enough to apply in transition and upper shelf regions of a fracture toughness transition temperature curve. The method is extensively verified by experimental and analytical investigations, and compared with other single specimen methods used for dynamic fracture toughness determination.

  10. Anodic corrosion of lead, tin and lead-tin alloys in sulphuric acid solutions. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Salmi, K.


    The electrochemical behavior of lead and tin and the effect of tin on the anodic behavior of lead in sulfuric acid solutions has been studied in relation to the corrosion of the positive grid of the lead acid battery. The release of soluble Pb(IV) species into sulfuric acid during the anodic polarization of lead has been mapped using the ring-disk electrode technique and their role in the electrochemistry of lead is discussed. Part of the tetravalent products formed on lead are reduced only at high negative potentials. The usefulness of the rotating ring-disk electrode for the determination of different soluble corrosion products has been demonstrated. Mechanisms for tin dissolution in different regions (open circuit, active dissolution and passive region) have been proposed. Ex situ surface analysis of the anodic layer formed on the tin electrode showed this to be mainly SnO.

  11. Competitiveness and trade policy problems in agricultural exports: The case of Colombia. Doctoral thesis project.

    Directory of Open Access Journals (Sweden)

    Jahir Enrique Lombana Coy


    Full Text Available Este estudio explora el estado actual y el potencial competitivo de las exportaciones agrícolas colombianas a los mercados de Estados Unidos y la Unión Eurpea. Los mercados de estos paises industrializados se constituyen en los más importantes para Colombia, pero al mismo tiempo tienen varias restricciones en el sector agrícola. Este estudio mostrará que la competitividad no es solamente una función de los impedimentos locales o internacionales tales como la pobreza institucional, la baja capacidad tecnológica, la disponibilidad de capital, capital humano y mano de obra, sino también de impedimentos externos como el acceso a los mercados. Por lo tanto, éste es un importante objetivo del presente estudio con el objeto de proyectar posibles escenarios para el comercio colombiano, a fin de investigar la eliminación de estas restricciones. En la parte empírica se enfatizará en los impactos de las restricciones externas en el sentido de un estudio econométrico, sin embargo, la influencia de las restricciones internas será discutida como tal.   La hipótesis central del trabajo sostiene que la eliminación de las restricciones de mercado en Estados Unidos y en la Unión Europea puede tener un importante impacto para la competitividad colombiana aunque esto no puede garantizar el crecimiento de las exportaciones nacionales sino se solucionan algunos problemas internos. Solamente la parte de las políticas comerciales de esta hipótesis puede ser evaluada en un estudio econométrico. El papel de los factores internos puede ser evaluado en el marco de un análisis del ambiente en el cual las exportaciones tienen lugar (informes macroeconómicos, estudios del Banco de la República. exportaciones corporativas, instituciones de crédito, segmentos de mercado. programas de asistencia técnica y otros.   Una importante contribución de este estudio consiste en la incorporación más comprensiva e interdisciplinaria de las teorías para explicar el comercio internacional. La teoría de la competitividad tiene un punto de vista multidimensional que analiza desde los niveles microeconómicos a los macroeconómicos. Esto comprende factores internos y externos para explicar los cambios en los flujos comerciales.   Para el desarrollo de los países, y especialmente para Colombia, las políticas del sector agrícola tienen implicaciones en aspectos económicos, políticos y sociales. Este estudio se propone desarrollar fundamentos empíricos y teóricos de la competitividad como soporte de las decisiones de políticas de mercado en los sectores público y privado.

  12. Congenital malformations in experimental diabetic pregnancy: aetiology and antioxidative treatment. Minireview based on a doctoral thesis. (United States)

    Simán, M


    Diabetes mellitus in pregnancy causes congenital malformations in the offspring. The aim of this work was to characterize biochemical and morphologic anomalies in the conceptus of an animal model of diabetic pregnancy. In addition, a preventive treatment against diabetes-induced dysmorphogenesis was developed. Congenital cataract was often found in the offspring of diabetic rats. The fetal lenses had increased water accumulation, sorbitol concentration and aldose reductase activity compared to control lenses. The results suggest that the cataracts form via osmotic attraction of water due to sorbitol accumulation in the fetal lens. Another set of malformations, with possible neural crest cell origin, occurred frequently in offspring of diabetic rats. These included low set ears, micrognathia, hypoplasia of the thymus, thyroid and parathyroid glands, as well as anomalies of the heart and great vessels. Furthermore, diabetes caused intrauterine death and resorptions more frequently in the late part of gestation. When the pregnant diabetic rats were treated with the antioxidants butylated hydroxytoluene, vitamin E or vitamin C, the occurrence of gross malformations was reduced from approximately 25% to less than 8%, and late resorptions from 17% to 7%. This suggests that an abnormal handling of reactive oxygen species (ROS) is involved in diabetes-induced dysmorphogenesis in vivo. Indeed, an increased concentration of lipid peroxides, indicating damage caused by ROS, was found in fetuses of diabetes rats. In addition, embryos of diabetic rats had low concentrations of the antioxidant vitamin E compared to control embryos. These biochemical alterations were normalized by vitamin E treatment of the pregnant diabetic rats. The antioxidants are likely to have prevented ROS injury in the embryos of the diabetic rats, in particular in the neural crest cells, thereby normalizing embryonic development. These results provide a rationale for developing new anti-teratogenic treatments for pregnant women with diabetes mellitus. PMID:9394431

  13. Evaluation of photodissociation coefficient calculations for use in atmospheric chemical models. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Petropaviovskikh, I.


    The chemistry of the atmosphere is strongly influenced by solar radiation, In addition to the obvious heating effect, solar radiation at visible and ultra-violet (UV) wavelengths drives atmospheric chemistry by photodissociating relatively stable molecules into usually highly reactive fragments. Photodissociation coefficients (J-values) describe quantitatively the frequency of atmospheric photolysis reactions, and therefore it is important to calculate them accurately. The author has examined a number of outstanding problems in the calculation of J-values.

  14. Fatigue crack growth behavior of a titanium matrix composite under thermomechanical loading. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Blatt, P.A.


    The crack growth characteristics of a 4-ply, unidirectional, titanium matrix composite, SCS-6/ti-6Al-2Sn4Zr-2Mo, subjected to thermomechanical fatigue were investigated. A linear summation model was developed to predict the isothermal and thermomechanical fatigue (TMF) crack growth rates of the composite. The linear summation approach assumes the total fatigue crack growth rate is a combination of a cycle-dependent and a time-dependent component. To assist the modeling effort, a series of isothermal, in-phase, and out-of-phase crack growth test were conducted. The test temperatures ranged from 15000 to 53800 and the fastest thermal frequency was 0.0083 Hz. With the excepton of the 15000 isothermal test, the model was able to correlate all the baseline fangue crack growth test data between oK of 50 to 9OMPa. In additon, the model was able to predict the fatigue crack growth rate of a proof test which involved a continual change in temperature range and load range to produce a constant crack growth rate. The proof test began under isothermal conditions at the maximum temperature and ended under in-phase TMF conditions.

  15. Experimental studies of sputtering on zirconium analyzed using modified Roosandaal Sanders theory. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Schomber, P.R.


    An ion optics system utilizing a wein filter velocity selector has been modeled and characterized for use as an ion source for an instrument to measure high resolution angular distributions of sputtered neutral atoms. Laser induced fluorescence detection techniques are used to measure ground state and first excited state sputtering angular distributions on a polycrystalline zirconium foil using argon and nitrogen sputter gases. The incident ion beam impact angle has been varied from 15 deg to 75 deg as measured from surface normal and the wein filter velocity selector has been used to select N2+ and N+ ion beams from the nitrogen ion beam. The experimental data gathered are compared to Roosandaal Sanders analytical sputtering theory along with data on xenon and neon. Roosandaal Sanders theory reproduces the near surface normal sputtering behavior but rapidly breaks down as the incident ion beam impact angle moves toward the surface. Modifications to the Roosandaal Sanders equation to introduce adjustable fitting parameters and non-linear least squares fitting of the experimental data to these parameters has been accomplished. The results are discussed relating the fitting parameters to physical constants based in Roosandaal Sanders Theory. Discrepancies in the theory are addressed with extensive discussion on ion surface interaction.

    Energy Technology Data Exchange (ETDEWEB)

    Kettunen, J.


    The general aim of all water resources modelling is to cover the broadest possible range of empirical facts with the smallest possible set of hypotheses. The study, which summarizes eight earlier publications, undertook to investigate practical techniques to attain the goal. The aims of the study were to develop methods for structural characterization, optimal observational design and for choice of the best model structure from among rival candidates. The problems were analyzed using the theory of optimal experimental design. A method to detect and identify non-linear dependency among model parameters was suggested. The method is based on the logarithmic transformation of parameter space and the principal component analysis of the Fisher information matrix. The technique can also be used to approximate the admissible level of the observational error. The non-linear D-optimal design of observations was studied.

  18. Bystander cells and prognosis in Hodgkin lymphoma. Review based on a doctoral thesis. (United States)

    Molin, Daniel


    Hodgkin lymphoma (HL) is characterised histologically by a minority of malignant Hodgkin and Reed-Sternberg (HRS) cells surrounded by benign cells, and clinically by a relatively good prognosis. The treatment, however, leads to a risk of serious side effects. Knowledge about the biology of the disease, particularly the interaction between the HRS cells and the surrounding cells, is essential in order to improve diagnosis and treatment. HL patients with abundant eosinophils in the tumours have a poor prognosis, therefore the eosinophil derived protein eosinophil cationic protein (ECP) was studied. Serum-ECP (S-ECP) was elevated in most HL patients. It correlated to number of tumour eosinophils, nodular sclerosis (NS) histology, and the negative prognostic factors high erythrocyte sedimentation rate (ESR) and blood leukocyte count (WBC). A polymorphism in the ECP gene (434(G>C)) was identified and the 434GG genotype correlated to NS histology and high ESR. The poor prognosis in patients with abundant eosinophils in the tumours has been proposed to depend on HRS cell stimulation by the eosinophils via a CD30 ligand (CD30L)-CD30 interaction. However, CD30L mRNA and protein were detected in mast cells and the predominant CD30L expressing cell in HL is the mast cell. Mast cells were shown to stimulate HRS cell lines via CD30L-CD30 interaction. The number of mast cells in HL tumours correlated to worse relapse-free survival, NS histology, high WBC, and low blood haemoglobin. Survival in patients with early and intermediate stage HL, diagnosed between 1985 and 1992, was generally favourable and comparatively limited treatment was sufficient to produce acceptable results for most stages. The majority of relapses could be salvaged. Patients treated with a short course of chemotherapy and radiotherapy had an excellent outcome. In conclusion prognosis is favourable in early and intermediate stages and there are possibilities for further improvements based on the fact that mast cells and eosinophils affect the biology and prognosis of HL.

    Full Text Available By passing the instruction period and increase of graduate students and also research budget, knowledge of accounting in Iran entered to the field of research in a way that number of accounting projects has been implemented in the real world. Because of that different experience in implementing the accounting standards were achieved. So, it was expected the mentioned experiences help to solve the financial problems in country, in spite of lots of efforts which were done for researching; we still have many financial and accounting problems in our country. PHD projects could be considered as one of the important solutions to improve the University subjects including accounting. PHD projects are considered as team work job and it will be legitimate by supervisor teams in universities.It is obvious that applied projects should solve part of the problems in accounting field but unfortunately it is not working in the real world. The question which came in to our mind is how come that the out put of the applied and knowledge base projects could not make the darkness of the mentioned problems clear and also why politicians in difficult situations prefer to use their own previous experiences in important decision makings instead of using the consultant’s knowledge base suggestions.In this research I’m going to study, the reasons behind that prevent the applied PHD projects from success in real world which relates to the point of view that consider the political suggestions which are out put of knowledge base projects are not qualified enough for implementation. For this purpose, the indicators of an applied PHD project were considered and 110 vise people were categorized the mentioned indicators and then in a comprehensive study other applied PHD accounting projects were compared to each other.As result, in this study problems of the studied researches were identified and a proper and applied model for creating applied research was developed.

  2. Biogeochemistry of (210)Pb and (210)Po in fresh waters and sediments. Doctoral thesis

    International Nuclear Information System (INIS)

    The geochemical cycling of (210)Pb in a Massachusetts lake was studied. A mass balance for the epilimnion showed that (210)Pb inputs by precipitation were matched by outputs on settling particles, so direct uptake by bottom sediments was inconsequential. Below the epilimnion, vertical mixing was very low because of a steep temperature/density gradient, and this limited vertical transport. Anoxic conditions caused remobilization of iron and (210)Pb, which reprecipitated at the oxycline and returned to the bottom via settling. Below the zone of precipitation, (210)Pb and iron distributions resulted from constant release from anoxic sediments and dilution in the water column. Sediment (210)Pb distributions were caused by sedimentation and Fickian transport. The Fickian component was equal to the pore water diffusive flux. In pore waters, (210)Pb and (210)Po were 100 times greater that in overlying water and had steep concentration gradients, unlike Fe, Mn, S(-II), and alkalinity. (210)Pb partition coefficients decreased from 15000 to 1500 with depth controlled by sorption on iron oxides. Remobilization to the water column comes from a thin layer of iron-rich floc near the sediment/water interface. Deeper in the cores, diffusive transport can cause redistribution of (210)Pb to an extent that can affect (210)Pb dating

  6. Healthy Doctors – Sick Medicine

    Directory of Open Access Journals (Sweden)

    Olaf Gjerløw Aasland


    Full Text Available Doctors are among the healthiest segments of the population in western countries. Nevertheless, they complain strongly of stress and burnout. Their own explanation is deprofessionalisation: The honourable art of doctoring has been replaced by standardised interventions and production lines; professional autonomy has withered. This view is shared by many medical sociologists who have identified a “golden age of medicine,” or “golden age of doctoring,” starting after World War II and declining around 1970. This article looks at some of the central sociological literature on deprofessionalisation, particularly in a perspective of countervailing powers. It also looks into another rise-and-fall model, proposed by the medical profession itself, where the fall in professional power was generated by the notion that there are no more white spots to explore on the map of medicine. Contemporary doctoring is a case of cognitive dissonance, where the traditional doctor role seems incompatible with modern health care.Keywords: deprofessionalisation, professional autonomy, cognitive dissonance, golden age of doctoring

  7. Profile of the Nontraditional Doctoral Degree Student (United States)

    Offerman, Michael


    What type of individual pursues a nontraditional doctoral degree? Although answering this question is the main purpose of this chapter, there is an underlying story that provides context for how and why these individuals came to pursue a doctoral degree. The tremendous growth in the number of doctoral students and doctoral degree-granting…

  8. Developing doctoral scientists for drug discovery: pluridimensional education required. (United States)

    Janero, David R


    Research universities continue to produce new scientists capable of generating knowledge with the potential to inform disease etiology and treatment. Mounting interest of doctoral-level experimental science students in therapeutics-related research careers is discordant with the widespread lack of direct drug-discovery and development experience, let alone commercialization success, among university faculty and administrators. Likewise, the archetypical publication- and grant-fueled, principal investigator (PI)-focused academic system ("PI-stan") risks commoditization of science students pursuing their doctorates as a labor source, rendering them ill-prepared for career options related to therapeutics innovation by marginalizing their development of "beyond-the-bench" professional skills foundational to modern drug-discovery campaigns and career fluency. To militate against professionalization deficits in doctoral drug-discovery researchers, the author--a scientist-administrator-consultant with decades of discovery research and development (R&D), business, and educator experience in commercial and university settings--posits a critical need for pluridimensionality in graduate education and mentorship that extends well beyond thesis-related scientific domains/laboratory techniques to instill transferable operational-intelligence, project/people-management, and communication competencies. Specific initiatives are advocated to help enhance the doctoral science student's market competitiveness, adaptability, and navigation of the significant research, commercial, and occupational challenges associated with contemporary preclinical drug-discovery R&D.

  9. A family of doctors over 250 years: innovation and controversy. (United States)

    Watkins, Peter J


    A family of Watkins doctors originating in the Northamptonshire town of Towcester included 13 doctors in seven generations during 250 years. In each generation there were between one and four doctors. Three doctors involved themselves actively in innovative yet controversial practises, described in their own writings and publications. Timothy Watkins' (1755-1834) own handwritten lecture notes describe the problems affecting an 18th-century man-midwife, while his accounts book provides insights into his lifestyle. The concept of the waterborne spread of cholera during the 1854 epidemic in Towcester is described by Robert Webb Watkins (1822-1901) during the same year as the observations made by John Snow (1813-58). John Webb Watkins (1833-1903) in his MD thesis (1856) describes his use of chloroform in labour in Towcester during the early 1850s, followed by self-experimentation with chloroform administered to him between 40 and 50 times by Sir James Young Simpson (1811-70) in Edinburgh. Descriptions of the two 19th-century general practitioners offer insights into the exemplary extent of their civic involvement in all walks of local community life, and of their family ties.

  13. Doctorate Holders: Career, Demand, International Mobility


    Laudeline Auriol


    Doctorate holders represent a crucial human resource for research and innovation. While they benefit from an employment premium, doctoral graduates encounter a number of difficulties, notably in terms of working conditions. The labour market of doctoral graduates is more internationalized than that of other tertiary-level graduates, and the doctoral population is a highly internationally mobile one. The paper explores the reasons for migration of doctorate holders and challenges they face ent...

  15. [The clown doctor: an introduction]. (United States)

    Rösner, M


    In the literature, increasing numbers of practitioners have reported their experience using clown doctors in geriatric settings. The reports agree on the positive effects on persons with dementia and also on their caregivers. However, empirical studies on its effectiveness are rare. This article presents the field of activity of a clown doctor in geriatric settings as well as an overview of current scientific research on the topic and the effects on persons with dementia and nursing staff. It will be become clear that the clown doctor is a supporting therapeutic intervention. Through the clown representation, it is possible to obtain access to and interact with a person with dementia, thus, maintaining social contact of the patient with his/her environment. This effect leads to an increase of well-being and contributes to a reduction of problematic behavior. In addition to reduced workload and relief for the nursing staff, it has a positive effect on the working atmosphere. PMID:20033816

  16. Solo doctors and ethical isolation. (United States)

    Cooper, R J


    This paper uses the case of solo doctors to explore whether working in relative isolation from one's peers may be detrimental to ethical decision-making. Drawing upon the relevance of communication and interaction for ethical decision-making in the ethical theories of Habermas, Mead and Gadamer, it is argued that doctors benefit from ethical discussion with their peers and that solo practice may make this more difficult. The paper identifies a paucity of empirical research related to solo practice and ethics but draws upon more general medical ethics research and a study that identified ethical isolation among community pharmacists to support the theoretical claims made. The paper concludes by using the literary analogy of Soderberg's Doctor Glas to illustrate the issues raised and how ethical decision-making in relative isolation may be problematical. PMID:19880707

  17. [Medical esthetics in the works of Polish doctors on the turn of the XIXth century]. (United States)

    Baranski, J


    The paper determines the objects of medical esthetics and the use of what is esthetic in doctor's practice and in medicine. The thesis of the paper is the assumption that medicine emerges out of esthetic distance. It is created by culture forms due to which biologicality of human body is restrained and subordinated. Medical esthetics examines these forms as well as their esthetic expressions in the art of therapy. The above assumption is documented by presenting the esthetic ideas of Polish doctors on the turn of the XIXth century. These ideas are represented first of all by: Zygmunt Kramsztyk, Henryk Nusbaum, Edmund Biernacki, Wladyslaw Bieganski, Heliodor Swiecicki and Wladyslaw Szumowski. The esthetic concepts and statement of the Polish doctors determine the limits of the objects of medical esthetics in which the doctor becomes the esthetic subject - creator of esthetic beauty, where as the medical art becomes esthetic form of medical practice.

    Bertens, R M; Huisman, F G


    This article outlines the historical development of the principle of patients' free choice of doctor in the Netherlands. Far from being the result of debates on patients' rights, this principle was used instead as an instrument by the medical profession to gain a foothold in the power relations between doctors and sickness funds back in the early 20th-century. This development created a medical power bloc that lasted for most of that century and forced sickness funds and private insurers to start organizing in this fashion too. Therefore, when the new market ideology of introducing competition in health care was introduced in 1987, the fields of health provision and insurance were already defined by a high degree of cartelization. These relations lingered even after the introduction of regulated competition in 2006. Knowledge of this history therefore leads to a better understanding of current debates and problems in the organization of Dutch health care. PMID:27353160

    Effective doctor-patient communication is a central clinical function in building a therapeutic doctor-patient relationship, which is the heart and art of medicine. This is important in the delivery of high-quality health care. Much patient dissatisfaction and many complaints are due to breakdown in the doctor-patient relationship. However, many doctors tend to overestimate their ability in communication. Over the years, much has been published in the literature on this important topic. We re...

  17. Doctoral Dissertation Supervision: Identification and Evaluation of Models

    Directory of Open Access Journals (Sweden)

    Ngozi Agu


    Full Text Available Doctoral research supervision is one of the major avenues for sustaining students’ satisfaction with the programme, preparing students to be independent researchers and effectively initiating students into the academic community. This work reports doctoral students’ evaluation of their various supervision models, their satisfaction with these supervision models, and development of research-related skills. The study used a descriptive research design and was guided by three research questions and two hypotheses. A sample of 310 Ph.D. candidates drawn from a federal university in Eastern part of Nigeria was used for this study. The data generated through the questionnaire was analyzed using descriptive statistics and t-tests. Results show that face-to-face interactive model was not only the most frequently used, but also the most widely adopted in doctoral thesis supervision while ICT-based models were rarely used. Students supervised under face-to-face interactive model reported being more satisfied with dissertation supervision than those operating under face-to-face noninteractive model. However, students supervised under these two models did not differ significantly in their perceived development in research-related skills.

    This study looks at the topic of women's education as considered by the first two women to receive the degree of Doctor in Medicine from a Spanish university. Delores Aleu and Martina Castells decided to present as a doctoral thesis the development of an issue of particular relevance during the final decades of the 19th century. The importance given to public education and the difficulties young women encountered in participating under the same conditions as young men led these two women--who both held a bachelor's degree--to raise the issue and defend personal and social reasons that justified their full participation in different levels of education.

  3. Doctoral Theses of History of Education in the Database TESEO (Spain 2000-2010

    Directory of Open Access Journals (Sweden)

    Carmen Sanchidrián Blanco


    Full Text Available The analysis of doctoral thesis conducted in a scientific field is one of the pillars for the status of the field and this has been raised within the project Mapping the Discipline History of Education. From the works already presented about the thesis in France, Switzerland, Portugal and Italy, we study the thesis included in the TESEO data base which have among their descriptors «History of education» in 2000, 2005 and 2010. In the 83 doctoral thesis localized, we have analyzed variables such as national or local character, the study period and the duration. As they have all in common that descriptor, we have also considered the situation of that one in relation to the other descriptors for each thesis as a possible indicator of the concept that the authors have about this discipline. The results are disaggregated by year and significant changes can be appreciated. Further studies including the content of the doctoral thesis may refine the results presented here. The TESEO database, with certain limitations, is an indispensable source in these studies. However, searches cannot be limited to the most obvious descriptors and must include keywords in the title and the summary. Some confusion about the very concept of discipline is clearly observed. A careful preparation of the records of this database will improve its effectiveness. How to reference this article Sanchidrián Blanco, C. (2016.

  18. Doctor's dilemma (medical decision making)

    International Nuclear Information System (INIS)

    Disagreement between experts is presumed to be uncommon in medical diagnosis. Radiology is considered to be a particularly objective means of diagnosis and expert radiographic interpretation is expected to be infallible. Five military radiologists were made to review independently chest radiographs of 1256 patients recorded in four image formats and interpret each as positive or negative for tuberculosis. The results were unexpected. Ability to detect tuberculosis varied little between various image formats but the extent of disagreement between doctors was remarkable. The number of cases judged positive varied from 56 to 100 among the five readers. Of cases judged positive at least once, the mean rate of disagreement between pairs of readers was 19%. The validity of these findings have been confirmed repeatedly in several subsequent trials. Other diagnostic modalities show equally surprising rates of diagnostic dissonance. Extensive observer disagreement was found to be a universal problem in medical diagnosis, giving credence to the proverbial adage that 'no two doctors agree'. The magnitude of disagreement between experts is the principal theoretic problem of diagnosis. Even a stochastic theory of diagnosis is devised which accounts for the disagreement between experts, where the disagreement approaches a theoretic maximum even for ideal diagnosticians

  20. Root doctors as providers of primary care. (United States)

    Stitt, V J


    Physicians in primary care recognize that as many as 65 percent of the patients seen in their offices are there for psychological reasons. In any southern town with a moderate population of blacks, there are at least two "root doctors." These root doctors have mastered the power of autosuggestion and are treating these patients with various forms of medication and psychological counseling. This paper updates the practicing physician on root doctors who practice primary care. PMID:6887277

  2. Doctoral education in the nuclear sector

    International Nuclear Information System (INIS)

    Doctoral education is a major priority for European universities. In the context of the Bologna Process the importance of doctoral education as the third cycle of higher education and the first stage of a young researchers career, and thus in linking the European Higher Education and Research Areas, was first highlighted in the 2003 Berlin Report. The core component of doctoral training is the advancement of knowledge through original research. considering the need for structured doctoral programs and the need for transparent supervision and assessment, we note that the normal workload of the third cycle in most countries would correspond 3-4 years full time. This is spirit of the new Spanish Doctoral Law. Then, universities should ensure that their doctoral programmes promote interdisciplinary training and the development of transferable skills, thus meeting the needs of the wider employment market. We need to achieve and overall increase in the numbers of doctoral candidates taking up research careers as early stage researchers and also increase the employability as a normal way as it is the case of other advance countries. In Spain, universities with doctoral nuclear programmes and the CIEMAT, with the sponsorship of the nuclear sector, a doctoral school in nuclear science and engineering should be created to enhance the research careers of Young students for the future of nuclear activities in Spain.

  15. Methodological Innovation in Practice-Based Design Doctorates

    Directory of Open Access Journals (Sweden)

    Joyce S. R. Yee


    Full Text Available This article presents a selective review of recent design PhDs that identify and analyse the methodological innovation that is occurring in the field, in order to inform future provision of research training. Six recently completed design PhDs are used to highlight possible philosophical and practical models that can be adopted by future PhD students in design. Four characteristics were found in design PhD methodology: innovations in the format and structure of the thesis, a pick-and-mix approach to research design, situating practice in the inquiry, and the validation of visual analysis. The article concludes by offering suggestions on how research training can be improved. By being aware of recent methodological innovations in the field, design educators will be better informed when developing resources for future design doctoral candidates and assisting supervision teams in developing a more informed and flexible approach to practice-based research.

  16. Family doctors and clinical trials

    Directory of Open Access Journals (Sweden)

    Pierclaudio Brasesco


    Full Text Available There is a growing awareness that research in primary care is needed to provide excellent clinical and population-based care, to develop effective health systems and policies, and to educate future primary care professionals and researchers. The relevance of research undertaken in primary care is unquestionable: the results of researches conducted in other settings has limited relevance because primary care encounters health problems rarely managed in other sectors of health care (i.e. low probability of major acute disease and high prevalence of comorbidity. From legislative aspects to limits and difficulties of application, the article underlines the importance of research in primary care in the Italian context, where this kind of activity is almost absent. An example, concerning the Genova ASL 3, is reported to suggest strategies to promote and improve research as an integral component of family doctors skills.

  17. Publishing Time-Frame Evaluation for Doctoral Students in United Kingdom

    Directory of Open Access Journals (Sweden)

    Andrada Elena URDA-CÎMPEAN


    Full Text Available The first objective of the study was to compute the time to completion and publication of original scientific publications for medical doctoral students in the UK. A second objective was to evaluate if PhD theses format (monograph or publication-based can influence the time to completion and publication of original scientific publications. We assessed a small sample of free full text medical doctoral theses from universities in the United Kingdom (mostly from the University of Manchester, which have produced at least 2 original scientific publications by the end of the doctoral studies. The time elapsed between 2 consecutive publications from the same thesis was considered an approximation of the time to completion and publication of the second publication. In the case of prospective theses, the median time to completion and publication of original scientific publications from medical doctoral theses was 10.17 months. We found that there was a statistically significant difference between the time (to completion and publication medians of the publications from traditional theses format and of the publications from publication-based theses format. Time to completion and publication of original scientific publications for medical doctoral students needs to be further evaluated on a larger scale, based on more theses from several medical faculties in the UK.

    Full Text Available BACKGROUND : Disruptive behavior in a medical setting is defined as objectionable or offensive interpersonal behavior that leads to disruption of professional activities in the workplace. 1 It has been observed that majority of doctors do not show disruptive behavior in their day today conduct and only few doctors are identified for their disruptive behavior . Special commi ttee on professional conduct and ethics defines disruptive behavior in physicians as aberrant behavior manifested through personal interaction with physicians , hospital personnel , health care professionals , patients , family members or others which interferes with patient care or could reasonably be expected to interfere with the process of delivering quality care. 2 Common forms of disruptive behaviors generally seen amongst young doctors are use of abusive language , yelling or shouting at patients , colleagues and subordinate staff , showing in disciplined behavior and at times indulging in physical abuse. 3 - 4 STUDY DESIGN : Study was conducted at a tertiary care hospital where 614 health care professionals participated which included 108 doctors 432 nurs ing staff and 74 paramedical staff METHOD : Data collection was done by semi structured pretested questionnaire and was entered in Microsoft Excel and analyzed for frequency and percentages . RESULTS : 64 % doctor , 66% nursing staff and 50% of the paramedicals answered that they have seen doctors showing disruptive behavior at one time or the other . Not all the doctors show disruptive behavior but this type of aberrant behavior is seen mainly in2 - 3 percent of doctors only. While answering to the que stion as to the type of disruptive behavior , 57% health care professionals reported that commonest form of disruptive behavior noticed by them amongst doctors was yelling or shouting on junior staff , patients and colleagues . 47% answered that doctors with disruptive behavior do not follow laid down orders or

  7. Doctoral education in a successful ecological niche

    Christensen, Mette Krogh; Lund, Ole


    Scholarly communities are dependent on and often measured by their ability to attract and develop doctoral students. Recent literature suggests that most scholarly communities entail ecological niches in which the doctoral students learn the codes and practices of research. In this article, we...... explore the microclimate in an ecological niche of doctoral education. Based on a theoretical definition of microclimate as the emotional atmosphere that ties group members together and affects their actions, we conducted a case study that aimed to describe the key features of the microclimate in a...... successful ecological niche of doctoral education, and the ways in which the microclimate support the doctoral students’ learning. The methods we applied in the case study were based on short-term ethnographic fieldwork. The results reveal four key features of the emotional atmosphere in the microclimate...

  8. Burnout and Doctors: Prevalence, Prevention and Intervention. (United States)

    Kumar, Shailesh


    Doctors are exposed to high levels of stress in the course of their profession and are particularly susceptible to experiencing burnout. Burnout has far-reaching implications on doctors; patients and the healthcare system. Doctors experiencing burnout are reported to be at a higher risk of making poor decisions; display hostile attitude toward patients; make more medical errors; and have difficult relationships with co-workers. Burnout among doctors also increases risk of depression; anxiety; sleep disturbances; fatigue; alcohol and drug misuse; marital dysfunction; premature retirement and perhaps most seriously suicide. Sources of stress in medical practice may range from the emotions arising in the context of patient care to the environment in which doctors practice. The extent of burnout may vary depending on the practice setting; speciality and changing work environment. Understanding dynamic risk factors associated with burnout may help us develop strategies for preventing and treating burnout. Some of these strategies will be reviewed in this paper. PMID:27417625

  10. The thesis of stages fourteen years later (United States)

    Beeby, C. E.


    The author indicates the changes and additions he would make to his book ` The Quality of Education in Developing Countries' (1966) if he were re-writing it in 1980. He would make clearer that his primary interest is in a continuum of change, the process of growth of a school system, and that the `stages' are only a convenient non-mathematical artifact to make the thesis more useful to administrators and planners. In the light of more recent developments and experiences, he now gives new stress to the pluralism of objectives at the stage of Meaning, and discusses the political, social, cultural and financial reasons why a country may choose not to take the difficult step from stage III to stage IV. Recent forms of alternative education, particularly those embodying plans for lifelong education, offer some hope of bypassing his thesis of stages. More consideration is given to constraints other than that of teacher qualification, though the difficulty of changing the skills, habits, attitudes and purposes in the teaching profession remain the chief obstacle to qualitative growth. Particular attention is paid to `crash' programmes where processes that are, by their very nature, successive are compressed into simultaneous or almost simultaneous ones. Some implications of the thesis of stages for teacher training are briefly dealt with. Regarding the application of the thesis to secondary education, he maintains that a better model of growth would be one based on the capacity of secondary education to respond to the changing economic and social demands of the community. Finally, he suggests three methods of testing his hypotheses and pleads that more consideration be given to building up a body of educational, theory based on the experience of developing countries over the past three decades.

  15. Doctor's dilemma: Medical decision making

    International Nuclear Information System (INIS)

    How a doctor arrives at a decision is of interest to both the developed and the developing countries. The developed and the developing want to walk on the same road but from different directions: one wants to develop a little more and the other wants to develop a little less for cost containment. To justify nuclear medicine in a developing country we have to see nuclear medicine in a new role. It is not for putting the diagnostic labels, not for differential diagnosis as we have been conditioned to think so far. In a developing country it should be for differential management, How does it alter the management decision in respect to a particular patient? If management outcomes are restricted, there is no need for an investigation which does not help in any way the management of the patient. If there is no bypass surgery, what use is the thallium perfusion? Although primarily a diagnostic discipline for its justification and survival in the developing country it should lead to a sensible differential management

  16. Doctors' drinking habits and consumption of alcohol. (United States)

    Juntunen, J; Asp, S; Olkinuora, M; Aärimaa, M; Strid, L; Kauttu, K


    Alcohol consumption and drinking habits among Finnish doctors were studied as part of a survey of stress and burnout. A questionnaire containing 99 questions or groups of questions was sent to all 3496 practising doctors aged under 66 randomly selected from the registry of the Finnish Medical Association. Altogether 2671 doctors (76%) responded; this sample was representative of the Finnish medical profession. The average weekly consumption of alcohol during the past year and various aspects of drinking behaviour were assessed, and the presence or absence of symptoms and diseases often encountered among heavy drinkers and addicts was determined. The data were analysed separately for men and women, for those aged less than or equal to 40 and greater than 40, and for the men with high and low alcohol consumption and with high and low scores on the index of drinking habits. Selected variables related to work, stress, and coping were correlated with alcohol consumption and drinking behaviour. The median consumption of alcohol among male doctors was 4876 g (6.2 litres) and among female doctors 2226 g (2.8 litres) of absolute alcohol per person per year and was higher in those aged over 40. Beer was most commonly drunk by men and wine by women. Increased alcohol consumption was associated with older age, disappointment with career, heavy smoking, use of benzodiazepines, stress and burnout symptoms, suicidal thoughts, general dissatisfaction, and diseases related to alcohol. Drinking habits were heavier among doctors working in community health centres, those taking long sick leaves, younger doctors disappointed with their careers or the atmosphere at work, and older doctors immersed in their work. Alcohol consumption among doctors seems to be higher than that of the general population in Finland, and heavy drinking seems to be associated with stress and burnout. PMID:3142564

  17. When a Family Requests a White Doctor. (United States)

    Reynolds, Kimberly L; Cowden, John D; Brosco, Jeffrey P; Lantos, John D


    Parents sometimes request that a doctor of a particular race or ethnic group not care for their child. Such requests sometimes seem legitimate and other times seem offensive. The difference reflects a clash of fundamental values. Generally, we try to respect patient or parental preferences. Requests based on racist attitudes, however, do not seem worthy of respect. But where should we draw the line? In this ethics rounds, we present a situation in which parents requested a white doctor and analyze the ways in which doctors might think about and respond to such a request. PMID:26169433

  18. The legal relationship of doctor and hospital. (United States)

    Carlisle, J R


    While doctors working in hospitals have usually been regarded as independent contractors, liable to the patient and for whom the hospital may not be held liable by the patient, some recent cases are beginning to change this assumption, especially where the case is an emergency giving the patient no choice of doctor but the one on duty at the time. These changes have particular implications for the insurance situation, since hospitals are entitled to sue someone on whose behalf they have been found vicariously negligent. As a condition of hospital privileges, they may require evidence of the doctor's insurance protection against legal action. PMID:21283286

    Veldman, W.H.M.


    L.E.J. Brouwer made a mistake in the formulation of his famous bar theorem, as was pointed out by S.C. Kleene. By repeating this mistake several times, Brouwer has caused confusion. We consider the assumption underlying his bar theorem, calling it Brouwer’s Thesis. This assumption is not refuted by Kleene’s example and we use it to obtain a conclusion different from Brouwer’s. Thus we come to support a view first expressed and defended by E. Martino and P. Giaretta in [Martino 1981]. We also ...

  14. Mortality among Norwegian doctors 1960-2000

    Directory of Open Access Journals (Sweden)

    Hem Erlend


    Full Text Available Abstract Background To study the mortality pattern of Norwegian doctors, people in human service occupations, other graduates and the general population during the period 1960-2000 by decade, gender and age. The total number of deaths in the study population was 1 583 559. Methods Census data from 1960, 1970, 1980 and 1990 relating to education were linked to data on 14 main causes of death from Statistics Norway, followed up for two five-year periods after census, and analyzed as stratified incidence-rate data. Mortality rate ratios were computed as combined Mantel-Haenzel estimates for each sex, adjusting for both age and period when appropriate. Results The doctors had a lower mortality rate than the general population for all causes of death except suicide. The mortality rate ratios for other graduates and human service occupations were 0.7-0.8 compared with the general population. However, doctors have a higher mortality than other graduates. The lowest estimates of mortality for doctors were for endocrine, nutritional and metabolic diseases, diseases in the urogenital tract or genitalia, digestive diseases and sudden death, for which the numbers were nearly half of those for the general population. The differences in mortality between doctors and the general population increased during the periods. Conclusions Between 1960 and 2000 mortality for doctors converged towards the mortality for other university graduates and for people in human service occupations. However, there was a parallel increase in the gap between these groups and the rest of the population. The slightly higher mortality for doctors compared with mortality for other university graduates may be explained by the higher suicide rate for doctors.

  16. Second generation professional doctorates in nursing. (United States)

    Rolfe, Gary; Davies, Ruth


    This paper traces the increase in number and diversity of professional doctorates over the last two decades and discusses the evolution from first to second generation doctorates as a response to the rise of the knowledge economy and new understandings of knowledge-production. Distinctions between first and second generation doctorates are interpreted in the light of Gibbons et al. [Gibbons, M., Limoges, C., Nowotny, H., Schwartzman, S., Scott, P., Trow, M., 1994. The New Production of Knowledge: The Dynamics of Science and Research in Contemporary Societies. Sage, London] taxonomy of knowledge-production, and it is argued that second generation doctorates, based on Mode 2 knowledge-production, are not only relevant to the economy but also have the potential to transform practice. However, as this paper highlights, this reconceptualisation of the professional doctorate presents particular challenges to academia and the discipline of nursing, which centre upon the threats posed to the power and authority of the University by the radical nature of Mode 2 knowledge generation and application in the workplace. Implications of these threats are discussed in relation to the current debate about the rigour of professional doctorates and the call by some for a return to the traditional doctorate or PhD. We conclude that the discipline of nursing has much to gain from embracing, rather than retreating from, the challenges posed by second generation professional doctorates, and that these offer an alternative but no less academically sound education in preparing nurses to pay a full and active role at the theory-practice interface.

  17. Young doctors' views on alternative medicine.


    Reilly, D T


    A survey was undertaken to explore attitudes to alternative medicine among 100 general practitioner trainees. A positive attitude emerged from the 86 respondents, with 18 doctors using at least one alternative method themselves and 70 wanting to train in one or more. A total of 31 trainees had referred patients for such treatments; 12 of these doctors made referrals to non-medically qualified practitioners. The most commonly used alternative treatments were hypnosis, manipulation, homoeopathy...

  20. SAS doctors career progression survey 2013. (United States)

    Oroz, Carlos; Sands, Lorna R; Lee, John


    We conducted a national survey of Staff, Associate Specialists and Specialty (SAS) doctors working in sexual health clinics in the UK in 2013 in order to explore their career progression. The aim of the survey was to assess SAS doctors' experience in passing through the thresholds and to gather information about the adherence by SAS doctors and employers to the terms and conditions of service laid out by the new 2008 contract. Out of 185 responders, whom the authors estimate comprise 34% of the total workforce, 159 were on the new contract. Of those, most SAS doctors were women (84%), the majority (67%) worked less than nine programmed activities per week; only a few had intentions to join the consultant grade (15%), and a considerable minority (26%) were older than 54 years of age and likely to retire in the next ten years. The survey showed that most participating SAS doctors had undergone appraisal in the previous 15 months (90%), most had a job planning discussion (83%) with their employer and most had some allocated time for supporting professional activities (86%). However, a significant minority had no appraisal (10%), no job planning discussion (17%) and had no allocated supporting professional activities (14%), which allows time for career development in the specialty. Most SAS doctors, who had the opportunity, had progressed through the thresholds automatically (88%); some experienced difficulties in passing (8%) and only a few did not pass (4%). SAS doctors must ensure that they work together with their employer in order to improve adherence to the terms and conditions of service of the contract, which allow for career progression and benefit both the individual doctors and ultimately service provision.

  6. Doctoral education in the nuclear sector; La formacion de doctores en el sector nuclear

    Energy Technology Data Exchange (ETDEWEB)

    Minguez, E.


    Doctoral aducation is a major priority for European universities. In the context of the Bologna Process the importance of doctoral education as the third cycle of higher education and the first stage of a young researchers career, and thus in linking the European Higher Education and Research Areas, was first highlighted in the 2003 Berlin Report. The core component of doctoral training is the advancement of knowledge through original research. considering the need for structured doctoral programs and the need for transparent supervision and assessment, we note that the normal workload of the third cycle in most countries would correspond 3-4 years full time. This is spirit of the new Spanish Doctoral Law. Then, universities should ensure that their doctoral programmes promote interdisciplinary training and the development of transferable skills, thus meeting the needs of the wider employment market. We need to achieve and overall increase in the numbers of doctoral candidates taking up research careers as early stage researchers and also increase the employability as a normal way as it is the case of other advance countries. In Spain, universities with doctoral nuclear programmes and the CIEMAT, with the sponsorship of the nuclear sector, a doctoral school in nuclear science and engineering should be created to enhance the research careers of Young students for the future of nuclear activities in Spain.

  7. Permeability heterogeneity in cross-bedded sandstones: Impact on water/oil displacement in fluvial reservoirs. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Hartkamp-Bakker, C.A.


    This study focuses on quantitatively defining the permeability/capillary-pressure characteristics in a number of well-exposed analoges and cored reservoirs by minipermeametry. Average contrasts in permeability are determined for fluvial cross-bedding and combined with thin-section studies to characterize the grain size, sorting and compositional characteristics that determine permeability contrasts. In addition capillary pressure experiments of laminated samples were carried out to study the contrasting capillary-pressure characteristics between the laminae. Water/oil displacement through cross-bedding by numerical and physical modelling were performed in close corporation with reservoir engineers to increase the understanding of the geological and physical conditions under which movable-oil entrapment occurs. Finally, the likely percentages of movable oil that are initially trapped in a cross-bedded reservoir are estimated.

  8. Geochemical and fluid dynamic investigations into the nature of chemical heterogeneity in the earth's mantle. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Hauri, E.H.


    Variations in the abundances of elements and radiogenic isotopes in mantle derived periodotites and volcanic rocks are chemical integrals over time, space, and process, which ultimately contain information about the role of convection in the earth's mantle in creating, maintaining, and destroying geochemical heterogeneities. Successful inversion of these integrals extensive of these integrals requires extensive knowledge of the geochemical behavior of elements, the length scales of chemical variability, the evolution with time of geologic systems, the physical properties of mantle rocks, and the driving forces of phenomena which govern heat and mass transport in a dynamic earth. This dissertation attempts to add to this knowledge by examining the trace element and isotope geochemistry of mantle periodotites and oceanic island basalts, and by studying aspects of the flow of viscous fluids driven by thermal buoyancy.

  9. Transient body force effects on the dryout and rewet of a heated capillary structure. Doctoral thesis, January 1990-April 1994

    Energy Technology Data Exchange (ETDEWEB)

    Reagan, M.K.


    A transient, one-dimensional numerical code was developed to model the liquid flow in a non-uniformly heated, axial square groove. The groove was subjected to transient body forces up to approximately 0.51 m/s sq. Axial variation in meniscus levels, shear stress and heat transfer between the groove wall and the liquid, axial conduction through the liquid, evaporation and body forces were accounted for in the model. Dryout and rewet of the groove were allowed; the front location was determined using conservation of mass and linear extrapolation. A physical experiment was performed with a stainless steel plate into which eight square grooves were machined. Ethanol was used as the working liquid. One end of the plate was tilted relative to the other end and this tilt was varied with time, thereby providing the transient body force. The depth of the ethanol in the groove, and the dryout and rewet front locations, were experimentally measured. Within the uncertainty of the measurements, the numerical results from the code predicted the correct movement of liquid within the groove structure and also the correct position of the dryout and rewet fronts.

  10. Interfacial shear behavior and its influence on fiber damage in sapphire-reinforced gamma titanium aluminide composites. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Galbraith, J.M.


    The interfacial shear behavior and its influence on fiber damage in sapphire-reinforced TiAl composites was investigated using a combination of microscopic characterization, indentation crack growth results, fiber pushout testing, fiber displacement measurements, and computational analyses. Two interrelated phenomena were studied: (1) residual stresses and resulting damage within fibers intersecting a free surface and (2) fiber/matrix interfacial strength behavior. In the first aspect of this study, experimental observations, finite element analysis, as well as analytical computations were all used to analyze the evolution of fiber damage that was observed in fibers intersecting a free surface in sapphire-reinforced Ti-48Al-IV composites. Experimental observations indicate that, under certain conditions, surface cracks introduced during specimen preparation will propagate along the fiber axis due to thermally-induced residual stresses. Finite element computations predict that significant thermally-induced residual tensile stresses exist in sapphire fibers embedded within TiAl-based matrices when they intersect and are oriented normal to a free surface. Indentation crack growth behavior within the sapphire fibers provided experimental validation of the predicted stress state. Finally, the application of an exact elastic analysis indicates that tensile stresses also exist within fibers oriented parallel to and near a free surface.

  11. Linking laboratory and in situ activation analysis of rock-forming elements using a 14 Mev neutron source. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Truax, J.


    This work examines the ability of a borehole-conveyed delayed neutron activation system to perform elemental analysis of earth formations with the combination of a neutron generator and a large germanium spectrometer. High purity germanium spectrometers are now made large enough that detection efficiency rivals that of borehole-compatible scintillators. Elemental concentrations of silicon, aluminum, magnesium, and sodium are important quantities used in the characterization of rocks. A series of activation spectrometry experiments was performed on chemically pure compounds of these elements in a neutron moderating environment similar to what would pertain in a borehole measurement. Then, the geometry of the experimental setup was entered into a radiation transport modeling code based on a Monte Carlo process. The purpose of this exercise was to compare the measured responses with those predicted by the reaction cross sections in the library of the model, which are often ill-defined for high energy neutron interactions.

  12. Investigations of the hyperfine interactions in copper-oxide perovskites using (151)Eu and (57)Fe moessbauer spectroscopy. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Linden, J.


    In 1986, superconductivity was discovered in a perovskite-type material at an unprecedentedly high temperature. As no satisfactory theory describing high-Tc superconductivity has been developed and since not all the perovskite phases exhibiting superconducting properties have been explored, the field is still the focus of active research. This work strives to promote the basic understanding of the high-Tc superconducting materials. It is suggested that the results obtained here are part of those boundary conditions that any successful theory of high-Tc superconductivity must take into account. This overview begins with a survey of the various phases studied in the work, followed by the theory behind the methods used to characterize the materials. Finally the experimental conditions and the results are presented.

  13. Excitation and de-excitation mechanisms of Er-doped GaAs and AlGaAs. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Elsaesser, D.W.


    Electrical and optical characterization have been performed on GaAs and AlxGa1-xAs samples doped with Er either by ion implantation or during Molecular Beam Epitaxial (MBE) growth. Deep Level Transient Spectroscopy (DLTS) and Temperature-Dependent Hall Effect (TDH) measurements indicated the presence of two hole traps in Er-doped GaAs, at 35 and 360 meV above the valence band maximum. The former (shallower) center was thought to be due to Er substituting for a Ga atom (ErGa) and giving rise to an isoelectronic impurity potential. The second center was attributed to an Er atom occupying an interstitial position (Er(i)). Annealing studies performed on Er-implanted GaAs indicated that the ErGa center preferentially formed at higher annealing temperatures ( > 850 deg C), with the Er(i) reaching a maximum concentration at an annealing temperature of around 750 deg C. Optical characterization performed by Photoluminescence (PL) measurements showed that the Er(i) center gave a much stronger Er-related intra-4f shell emission. Mechanisms for the excitation of the 4f shells of these two centers are discussed. Similar optically active Eri centers may be forming in AlGaAs....Rare earth, Er, DLTS, Isoelectronic, GaAs, AlGaAs, Ion implantation, MBE, Luminescence, Hall effect.

  14. Marshall N. Rosenbluth Outstanding Doctoral Thesis Award Talk: Control of Non-Axisymmetric Fields With Static and Dynamic Boundary Conditions (United States)

    Paz-Soldan, C.


    Small deformations of the otherwise axisymmetric field, known as ``error fields'' (EFs), lead to large changes in global MHD stability. This talk will compare results from both 1) a line-tied screw-pinch with rotating conducting walls and 2) the DIII-D tokamak to illustrate that in both devices the EF has greatest effect where it overlaps with the spatial structure of its global kink mode. In both configurations the kink structure in the symmetry direction is well described by a single mode number (azimuthal m = 1 , toroidal n = 1 , respectively) and EF ordering is clear. In the asymmetric direction (axial and poloidal, respectively) the harmonics of the kink are coupled (by line-tying and toroidicity, respectively) and thus EF ordering is not straightforward. In the pinch, the kink is axially localized to the anode region and consequently the anode EF dominates the MHD stability. In DIII-D, the poloidal harmonics of the n = 1 EF whose pitch is smaller than the local field-line pitch are empirically shown to be dominant across a wide breadth of EF optimization experiments. In analogy with the pinch, these harmonics are also where overlap with the kink is greatest and thus where the largest plasma kink response is found. The robustness of the kink structure further enables vacuum-field cost-function minimization techniques to accurately predict optimal EF correction coil currents by strongly weighting the kink-like poloidal harmonics in the minimization. To test the limits of this paradigm recent experiments in DIII-D imposed field structures that lack kink-overlapping harmonics, yielding ~10X less sensitivity. The very different plasmas of the pinch and tokamak thus both demonstrate the dominance of the kink mode in determining optimal EF correction.

  15. Exponential characteristic spatial quadrature for discrete ordinates neutral particle transport in two-dimensional cartesian coordinates. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Minor, B.M.


    The exponential characteristic spatial quadrature for discrete ordinates neutral particle transport with rectangular cells is developed. Numerical problems arising in the derivation required the development of exponential moment functions. These functions are used to remove indeterminant forms which can cause catastrophic cancellations. The EC method is positive and nonlinear. It conserves particles and satisfies first moment balance. Comparisons of the EC method's performance to other methods in optically thin and thick spatial cells were performed. For optically thin cells, the EC method was shown to converge to the correct answer, with third order truncation error in the thin cell limit. In deep penetration problems, the EC method attained its highest computational efficiencies compared to the other methods. For all the deep penetration problems examined, the number of spatial cells required by the EC method to attain a desired accuracy was less than the other methods....

  16. [Modern esophageal surgery and late functional results as equations with several unknowns--Hungarian Academy of Sciences Doctoral Thesis]. (United States)

    Altorjay, Aron


    Using the same surgical method and anatomically ideal primary healing, the functional results could even be different later. Trying to identify various factors being responsible for the above differences, 637 patient's data, who underwent previous oesophago-gastric surgery between 1985-2005, were analyzed. Biochemical, histological and electrophysiological examinations had been evaluated. Developing hypertrophy-like metabolic changes and enteric ganglionitis as morphological alternations of LES muscles induced by GERD may be reasons for complaints after antireflux surgery. The marking of Z-line with endoscopic clips followed by an immediately upright contrast study and substractional evaluation is appropriate for detecting true short esophagus. Open surgical procedures are justified even in the new millennium in cases when the patient already underwent previous upper abdominal operations - due to an increased risk of injury because of adhesions - in cases of primarily recurrent paraesophageal hernias after an unsuccessful open and/or laparoscopic reconstruction, as well as in cases of reflux with complications. When adenocarcinomas of the gastro-oesophageal junction are examined preoperatively, the ratio of the performed catabolic - AMAN, CB, and DPP I - enzymatic activity of the tissue sample from the tumour and adjacent intact mucosa within 2 cm of the tumour may have a prognostic value even in the preoperative examination period, and neo-adjuvant treatment should be considered in these group of patients. The patients' post-operative complaints and symptoms change during the post-operative period and correlate with the parameters of the myoelectric and contractile activities of the "Akiyama stomach". Tachygastria seems to be the major pathogenetic factor involved in the contractile dysfunction. Gastro-jejuno-duodenal interposition represents an adequate 'second-best' method of choice if technical difficulties emerge with jejunal or colon interposition following limited resection of the oesophagus performed due to early Barrett's carcinoma or non-dilatable peptic stricture.

  18. Time-dependent modulation of moessbauer resonance: Experiments on gamma echo and double resonance phenomena. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Tittonen, I.


    In the present work, temporal aspects of nuclear recoil-free transitions are studied. Some of the results are analogous to those encountered earlier in Nuclear Magnetic Resonance and laser spectroscopy with some special features in the gamma ray regime. The main attention was focused on the interference effects of the classical gamma radiation field of the source and the field developed and emitted by a resonant absorber. The concept of classical phase modulation of gamma radiation was applied to develop a novel gamma echo phenomenon by causing a constructive rather than a destructive interference by a single phase change of the source radiation. When a periodical magnetic modulation was used with a frequency comparable to the natural linewidth, so called transient oscillations were observed. The experimental results were analyzed with high accuracy using the phase modulation theory. By increasing the frequency of the modulating magnetic field even further to match the resonance frequencies of the hyperfine split states, it was possible to establish conditions for another novel phenomenon, the double resonance in the gamma ray regime.

  19. Nicholas Metropolis Award for Outstanding Doctoral Thesis Work in Computational Physics Talk: Equation of State of the Dilute Fermi Gases (United States)

    Chang, Soon Yong


    In the recent years, dilute Fermi gases have played the center stage role in the many-body physics. The gas of neutral alkali atoms such as Lithium-6 and Potassium-40 can be trapped at temperatures below the Fermi degeneracy. The most relevant feature of these gases is that the interaction is tunable and strongly interacting superfluid can be artificially created. I will discuss the recent progress in understanding the ground state properties of the dilute Fermi gases at different interaction regimes. First, I will present the case of the spin symmetric systems where the Fermi gas can smoothly crossover from the BCS regime to the BEC regime. Then, I will discuss the case of the spin polarized systems, where different quantum phases can occur as a function of the polarization. In the laboratory, the trapped Fermi gas shows spatial dependence of the different quantum phases. This can be understood in the context of the local variation of the chemical potential. I will present the most accurate quantum ab initio results and the relevant experiments.

  1. Microbiological gas formation altering top sediment composition and its relation to the internal nutrient load in eutrophic lakes. Doctoral thesis

    Energy Technology Data Exchange (ETDEWEB)

    Matinvesi, J.


    The aim of this investigation was to gain more information on the biological process taking place in the lake sediments and to find measures to improve the condition of eutrophic lakes. In six central Finnish lakes representing different trophic states, the phosphatase enzyme activity, the number of acetic acid-, ferricphosphate-, and tricalcium- phosphate -utilizing bacteria, and the levels of organic substances were the highest in the top layer of every sediment profile. The top sediments reveal to a great extent a fixed relation of carbon to nitrogen and phosphorus so that biological processes, degradation and deformation, have probably affected the distribution of organic substances and nutrients in the top sediments of these Finnish lakes. This suggests that a part of the organic substances may be mobile within the `reactive zone` and may move to the uppermost sediment layer in the course of time in undisturbed lake sediments.

  2. Collaboration between radiological technologists (radiographers) and junior doctors during image interpretation improves the accuracy of diagnostic decisions

    International Nuclear Information System (INIS)

    Rationale and Objectives: In Emergency Departments (ED) junior doctors regularly make diagnostic decisions based on radiographic images. This study investigates whether collaboration between junior doctors and radiographers impacts on diagnostic accuracy. Materials and Methods: Research was carried out in the ED of a university teaching hospital and included 10 pairs of participants. Radiographers and junior doctors were shown 42 wrist radiographs and 40 CT Brains and were asked for their level of confidence of the presence or absence of distal radius fractures or fresh intracranial bleeds respectively using ViewDEX software, first working alone and then in pairs. Receiver Operating Characteristic was used to analyze performance. Results were compared using one-way analysis of variance. Results: The results showed statistically significant improvements in the Area Under the Curve (AUC) of the junior doctors when working with the radiographers for both sets of images (wrist and CT) treated as random readers and cases (p ≤ 0.008 and p ≤ 0.0026 respectively). While the radiographers’ results saw no significant changes, their mean Az values did show an increasing trend when working in collaboration. Conclusion: Improvement in performance of junior doctors following collaboration strongly suggests changes in the potential to improve accuracy of patient diagnosis and therefore patient care. Further training for junior doctors in the interpretation of diagnostic images should also be considered. Decision making of junior doctors was positively impacted on after introducing the opinion of a radiographer. Collaboration exceeds the sum of the parts; the two professions are better together.

  9. Thermal Signature Identification System (TheSIS) (United States)

    Merritt, Scott; Bean, Brian


    We characterize both nonlinear and high order linear responses of fiber-optic and optoelectronic components using spread spectrum temperature cycling methods. This Thermal Signature Identification System (TheSIS) provides much more detail than conventional narrowband or quasi-static temperature profiling methods. This detail allows us to match components more thoroughly, detect subtle reversible shifts in performance, and investigate the cause of instabilities or irreversible changes. In particular, we create parameterized models of athermal fiber Bragg gratings (FBGs), delay line interferometers (DLIs), and distributed feedback (DFB) lasers, then subject the alternative models to selection via the Akaike Information Criterion (AIC). Detailed pairing of components, e.g. FBGs, is accomplished by means of weighted distance metrics or norms, rather than on the basis of a single parameter, such as center wavelength.

  10. Using Doctoral Experience Survey Data to Support Developments in Postgraduate Supervision and Support

    Directory of Open Access Journals (Sweden)

    Lucy Johnston


    Full Text Available Provision of both high standards of thesis supervision and high quality research environments are required for doctoral candidates to flourish. An important component of ensuring quality provision of research resources is the soliciting of feedback from research students and the provision from research supervisors and institutions of timely and constructive responses to such feedback. In this manuscript we describe the use of locally developed survey instruments to elicit student feedback. We then demonstrate how actions taken in response to this student feedback can help establish a virtuous circle that enhances doctoral students’ research experiences. We provide examples of changes to supervisory practice and resource allocation based on feedback and show the positive impact on subsequent student evaluations. While the examples included here are local, the issues considered and the methods and interventions developed are applicable to all institutions offering research degrees.

    Schaefer, Corinna; Schwarz, Sabine


    Online doctor rating sites have been increasingly discussed in the past few years, but scientific papers on the issue are rare. Results of a recent study could show that online doctor rating sites do not support patients in identifying qualified doctors. Against this background, the German Medical Association and the National Association of Statutory Health Insurance Physicians have commissioned the German Agency for Quality in Medicine (ÄZQ) with developing quality standards for online doctor rating sites. The list of quality criteria, published in December 2009, contains 40 questions and defines the following main quality standards: data privacy, transparency in terms of operators and funding, a clear and understandable assessment procedure, a strict separation of content and advertisement, measures against defamation, discrimination and deception. At present,all German online doctor rating sites are being assessed according to the list of quality criteria by ÄZQ. The results will be published. PMID:21095610

  5. Interdisciplinary MSc and Doctoral Education in Climate System Science at the University of Hamburg (United States)

    Dilly, Oliver; Stammer, Detlef; Pfeiffer, Eva-Maria


    Modern education in climate system sciences is based on a number of disciplines such as meteorology, geophysics, oceanography, geosciences and also economics and social sciences. Facts across these disciplines are required to address the faced key issues related to climate change effectively. Climate experts need to have profound knowledge that can only be achieved in interdisciplinary MSc and PhD programs. In Europe, graduate students who completed a BSc degree are typically proceeding with MSc programs to increase knowledge and qualification. Afterwards, the participation in a doctoral program may follow. Many doctoral programs include courses supporting disciplinary methodological and scientific background in particular. Those courses derive either from advanced MSc programs or specific trainings. Typically, interdisciplinary exchange is difficult to achieve at any stage of disciplinary graduate programs. Recent developments showed the need to educate climate experts in interdisciplinary MSc programs in climate system sciences for both researchers and professionals outside the university. The University of Hamburg offers an interdisciplinary 2-yr MSc program in Integrated System Sciences with 120 ECTS (30 compulsory, 90 eligible) in English language. If the MSc student decides to proceed with a PhD thesis, he/she may not necessarily complete the MSc program but may start to work on a specific and disciplinary doctoral thesis for 3 years. Each doctoral student is guided by an advisory panel (AP) which meets at least bi-annually. The AP consists of a Principal Advisor, a Co-Advisor and a Chair of the panel who come from neighboring disciplines. The structured doctoral program with only 12 CPs includes interdisciplinary compulsory courses and tailor-made eligible expert courses. Summer schools and soft skill courses add to both MSc and doctoral programs. Accordingly, the new graduate school concepts in climate system sciences at the University of Hamburg supports

  7. Double Field Theory on Group Manifolds (Thesis)

    CERN Document Server

    Hassler, Falk


    This thesis deals with Double Field Theory (DFT), an effective field theory capturing the low energy dynamics of closed strings on a torus. It renders T-duality on a torus manifest by adding $D$ winding coordinates in addition to the $D$ space time coordinates. An essential consistency constraint of the theory, the strong constraint, only allows for field configurations which depend on half of the coordinates of the arising doubled space. I derive DFT${}_\\mathrm{WZW}$, a generalization of the current formalism. It captures the low energy dynamics of a closed bosonic string propagating on a compact group manifold. Its classical action and the corresponding gauge transformations arise from Closed String Field Theory up to cubic order in the massless fields. These results are rewritten in terms of a generalized metric and extended to all orders in the fields. There is an explicit distinction between background and fluctuations. For the gauge algebra to close, the latter have to fulfill a modified strong constrai...

Little attention, however, has been paid to the interpersonal aspect of the conversa⁃tion between doctors and patients, which is regarded as one of the most complex interpersonal relationships. Being dominant in the interaction, doctors’words, mainly in the form of questions, deserve more studies, especially for the interpersonal functions delivered. This study mainly focuses on this aspect.

    Sennekamp, Monika; Paulitsch, Michael A; Broermann, Marischa; Klingebiel, Thomas; Gerlach, Ferdinand M


    In Germany, medical doctorates are regularly criticized for their insufficient quality. In order to improve the quality of doctorates and to support doctoral candidates, a department-wide doctoral research program was established at the Goethe University of Frankfurt am Main in 2011 taking into account the practical needs of doctoral students at the School of Medicine. The program development proceeded in several steps: in the first step (2009/2010), a pilot study with eleven doctoral candidates was carried out at the Institute of General Practice. Their ratings of the perceived relevance and their own knowledge of 15 topics of scientific work were used to identify a provisional need for support. Subsequently an interdisciplinary panel of experts established the program throughout the faculty. Since its implementation, a requirements analysis in the form of questionnaires has been continuously carried out in order to assess the doctoral students' prior knowledge and their preferences expressed. At the same time, systematic searches for support programs in other medical fields have been conducted throughout Germany on several occasions. On the basis of the pilot study, the research results and the expert panel discussions the following topics were found to be particularly relevant: principles of good scientific practice, literature search, reference management, organization and structure of a doctoral thesis, formatting of Word documents, clinical epidemiology and data management. A specific, stepwise development process was used to design a concept for the faculty of medicine that pays close attention to the knowledge and interests of doctoral candidates. The establishment of the doctoral research program in Frankfurt and the results of its evaluation are presented in a second article (Paulitsch et al., 2016). PMID:26875038

    Full Text Available Abstract: Genre analyses and contrastive rhetoric studies have dealt with quite a number of genres of writing. However, genre analysts and contrastive rhetoric researchers have not carried out adequate analyses of doctoral prospectuses. This paper will, subsequently, address this issue by analyzing a genre of texts of doctoral prospectuses. The analysis will be focused on the sub-genre of “Background of the Study” of the prospectuses. Limitations of accessibility, however, have led this study to only focus on analyzing fourteen doctoral prospectuses written in English by Indonesian students of EFL accessible from the Graduate Program, State University of Malang, Indonesia. This situation suggests that the present study is preliminary. Preliminary, notwithstanding, the study will contribute to filling the gap of the under-researched issue of doctoral studies in Indonesia, particularly, those pertinent to the area of ELT. The analysis shows a tendency that the texts of Background of the Study do not show research spaces.

    Bruce, Christine; Stoodley, Ian; Pham, Binh


    As part of their journey of learning to research, doctoral candidates need to become members of their research community. In part, this involves coming to be aware of their field in ways that are shared amongst longer-term members of the research community. One aspect of candidates' experience we need to understand, therefore, involves how they…

  9. Private medical education--the doctor's perspective. (United States)

    Abdul Hamid, A K


    The Government's decision to drastically and speedily increase the number of doctors in the country needs to be reviewed. The standard and quality of health care does not depend on the number of doctors, but on the improvement of the health care infrastructure. Increasing the number of government medical schools and increasing the intake of students should be done on a need-to basis, with the above perspective in mind. The selection criteria of candidates must not be compromised and the teaching staff must be adequate and experienced. The number of doctors should be gradually increased over the years in tandem with the development of the health care infrastructure and the deployment of doctors must be directed at providing equitable care to the people at all economic levels and geographic locations. The strength of academic staff in existing government medical schools must be upgraded to provide high level of teaching and research, perhaps reinforced with the recruitment of suitably qualified and experienced foreign teachers. The infrastructure of existing government medical schools must be upgraded to cater for the gradual increasing demand for more doctors as the country develops. The selection of candidates for the government medical schools must be based on merit and without undue emphasis on ethnic considerations, for it is only in the arena of fair competitiveness that excellence can be born. The considerations of merit in selection must include assessment of attitude, self-development, moral ethics and reasoning. If the above perspectives are fully appreciated, then there is really no requirement for private medical colleges in Malaysia. PMID:11125516

  14. Instructable autonomous agents. Ph.D. Thesis (United States)

    Huffman, Scott Bradley


    In contrast to current intelligent systems, which must be laboriously programmed for each task they are meant to perform, instructable agents can be taught new tasks and associated knowledge. This thesis presents a general theory of learning from tutorial instruction and its use to produce an instructable agent. Tutorial instruction is a particularly powerful form of instruction, because it allows the instructor to communicate whatever kind of knowledge a student needs at whatever point it is needed. To exploit this broad flexibility, however, a tutorable agent must support a full range of interaction with its instructor to learn a full range of knowledge. Thus, unlike most machine learning tasks, which target deep learning of a single kind of knowledge from a single kind of input, tutorability requires a breadth of learning from a broad range of instructional interactions. The theory of learning from tutorial instruction presented here has two parts. First, a computational model of an intelligent agent, the problem space computational model, indicates the types of knowledge that determine an agent's performance, and thus, that should be acquirable via instruction. Second, a learning technique, called situated explanation specifies how the agent learns general knowledge from instruction. The theory is embodied by an implemented agent, Instructo-Soar, built within the Soar architecture. Instructo-Soar is able to learn hierarchies of completely new tasks, to extend task knowledge to apply in new situations, and in fact to acquire every type of knowledge it uses during task performance - control knowledge, knowledge of operators' effects, state inferences, etc. - from interactive natural language instructions. This variety of learning occurs by applying the situated explanation technique to a variety of instructional interactions involving a variety of types of instructions (commands, statements, conditionals, etc.). By taking seriously the requirements of flexible

    The human brain undergoes profound structural changes with development. It does not mature by simply growing, rather the transition to adulthood is a dynamic process with regionally specific patterns. However, there is no consensus on the timing and shape of growth trajectories of brain structures. In this thesis we capitalize on advances in multimodal MRI and use longitudinal study designs to map structural brain maturation and connectivity in typical and atypical children and adolescents. O...

  12. The brain is a context machine


    Nikolić, Danko


    A thesis is presented that the basic operational principle of the brain is to process each input in relation to the context in which it occurs—in space and time. The brain has evolved such that it knows no better or more fundamental approach to computation but contextual comparisons. A brain without context would be a whole another system, with a mind nothing like that of a human.

  13. Through doctors' eyes: A qualitative study of hospital doctor perspectives on their working conditions.

    LENUS (Irish Health Repository)

    McGowan, Yvonne


    BACKGROUND: Hospital doctors face significant challenges in the current health care environment, working with staff shortages and cutbacks to health care expenditure, alongside increased demand for health care and increased public expectations. OBJECTIVE: This article analyses challenges faced by junior hospital doctors, providing insight into the experiences of these frontline staff in delivering health services in recessionary times. DESIGN: A qualitative methodology was chosen. METHODS: Semi-structured in-depth interviews were conducted with 20 doctors from urban Irish hospitals. Interviews were recorded via note taking. Full transcripts were analysed thematically using NVivo software. RESULTS: Dominant themes included the following: (1) unrealistic workloads: characterised by staff shortages, extended working hours, irregular and frequently interrupted breaks; (2) fatigue and its impact: the quality of care provided to patients while doctors were sleep-deprived was questioned; however, little reflection was given to any impact this may have had on junior doctors own health; (3) undervalued and disillusioned: insufficient training, intensive workloads and a perceived lack of power to influence change resulted in a sense of detachment among junior doctors. They appeared immune to their surroundings. CONCLUSION: Respondents ascribed little importance to the impact of current working conditions on their own health. They felt their roles were underappreciated and undervalued by policy makers and hospital management. Respondents were concerned with the lack of time and opportunity for training. This study highlighted several \\'red flags\\

  15. Brain Network Modelling

    DEFF Research Database (Denmark)

    Andersen, Kasper Winther

    Three main topics are presented in this thesis. The first and largest topic concerns network modelling of functional Magnetic Resonance Imaging (fMRI) and Diffusion Weighted Imaging (DWI). In particular nonparametric Bayesian methods are used to model brain networks derived from resting state f...... for their ability to reproduce node clustering and predict unseen data. Comparing the models on whole brain networks, BCD and IRM showed better reproducibility and predictability than IDM, suggesting that resting state networks exhibit community structure. This also points to the importance of using models, which...... allow for complex interactions between all pairs of clusters. In addition, it is demonstrated how the IRM can be used for segmenting brain structures into functionally coherent clusters. A new nonparametric Bayesian network model is presented. The model builds upon the IRM and can be used to infer...

  17. Opinion of doctors about unmet needs of rural diabetics

    Directory of Open Access Journals (Sweden)

    Rohit Dixit


    Results: All the doctors who were involved in the study had different opinion. MBBS doctors are more aware than BHMS/BAMS/BUMS doctors about the minimum degree required doing a diabetic practice legally in India. Both the group of doctors believed that the needs of diabetic population in rural India are not properly addressed; the reason behind this was lack of qualified doctors (according to majority of BHMS/BAMS/BUMS doctors and lack of awareness among the rural patients (according to MBBS doctors. Both the doctors believe that MBBS doctors with some fellowship courses in diabetes can manage diabetes effectively (except serious complications. Conclusions: Both the doctors believe that MBBS doctors with some fellowship courses in diabetes can manage diabetes effectively (except serious complications. In India only MD (general medicine and endocrinologists are technically qualified to treat diabetes. MCI should come forward and recognize the fellowship courses by regularizing them with proper guidelines and protocol set up for the institution providing such courses and allow those doctors to practice in rural areas, so that diabetics' needs are addressed properly.

  20. Doctors' Knowledge of Viral Haemorrhagic Fevers. (United States)

    Lisk, Clifford; Snell, Luke; Haji-Coll, Michael; Ellis, Jayne; Sufi, Saaidullah; Raj, Rohit; Sharma, A; Smith, C


    Viral Haemorrhagic Fevers (VHF) such as Ebola Virus Disease (EVD) are of increasing concern to clinicians and public heath bodies across Europe and America due to the on-going epidemic in West Africa. We conducted an online study to assess clinicians' knowledge of VHF across six hospital sites in London. This showed suboptimal knowledge of Public Health England guidance, EVD epidemiology and the risk factors for acquiring VHF. Knowledge about VHF was dependent on seniority of grade with the most junior grade of doctors performing worse in several areas of the survey. Poor knowledge raises concerns that those at risk of VHF will be inappropriately risk stratified and managed. Education of doctors and other healthcare professionals about VHF is necessary to address these knowledge gaps. PMID:26305080
