    Full Text Available Food and Nutrition Security (FNS has an evolving nature and during the last decades its theoretical, conceptual, structural, practical and programmatic notions evolved significantly and approaches toward food and nutrition have changed drastically. Now, more than ever before, the issue is considered as a fundamental component of sustainable development globally. For a better grasp of the complexities of the field, we need to remind ourselves that “nutrition” as science has a history of more than 100 years while nutrition as a “factor” in “National development” has a history of around fifty years. Considering distinct levels of development status in different contexts, FNS pattern is non-monotonic even in one country. Accordingly, struggling against food and nutrition insecurity is very thought to deal with and multi disciplinary and multi sectorial approaches should be applied. Providing robust evidences to feed policy making processes is one of the main prerequisites for evidence informed policy making and repositioning nutrition as central to sustainable development. This is a professional duty of scholars in different sectors engaging with human development. The journal of Nutrition and Food Security (JNFS as a new journal in the field of food and nutrition security is trying to provide an excellent opportunity for researchers and scholars to publish their original works on approaches, challenges and solutions of food and nutrition hoping to provide data for decision makers to better design interventional programs aiming to eradicate food and nutrition insecurity.

    British painter Francis Bacon (1909-1992) was known for the eloquence with which he talked about his art. He was easy to talk to, and was interviewed countless times by numerous critics. However, when studying Bacon's paintings one soon comes across the published interviews with art critic and curator David Sylvester (1924-2001), who interviewed him as many as 18 times between 1962 and 1986. Art historian Sandra Kisters argues that Sylvester's interviews with Bacon are carefully constructed a...

    Full Text Available CORPUS studies have increasingly been of interest to music theorists, musicologists, and music psychology researchers, as is evident in the sheer number of excellent submissions to this special issue. The breadth and depth of these articles, as well as the insightful commentaries, make it seem only fitting to publish over two issues. The current issue contains five articles, eight commentaries, and one research report, and covers folk music, post-tonal music, jazz, Western art music, and the popular music found on Youtube. Eerola presents a model of melodic entropy that provides a nice framework for future information-theoretic work, while Roger Dean and Marcus Pearce present a new approach to modelling pitch-structure in post-tonal music. Frieler, Pfleiderer, Abeßer, and Zaddach give an analysis of jazz solos that demonstrates the role of a narrative arcs in improvisation. White and Quinn present a new corpus that makes use of vast compilations of web-based MIDI data, and demonstrates how such a corpus might be facilitate future musicological and music-theoretic research. Plazak focuses on Youtube as a corpus, and argues that the mutability of such a corpus facilitates our understanding of musical communication, as well as the important role of the listener in defining and re-defining such a dataset. It's encouraging to me both as an editor and practitioner of corpus methods that so many of those heavily involved with the field contributed to these two issues as either an author or a commentator. This issue also brings a number of changes on other fronts. Firstly, Nicola Dibben and Renee Timmers, who served as the journal's editors since Volume 7, have completed their editorial terms. They oversaw the transformation of the journal into a new Open Journal Systems platform, and were able to consistently produce issues that set a very high standard. Under their leadership, the journal both increased its accessibility (we now average more than 1

  19. Francis Bacon's behavioral psychology.

    Science.gov (United States)

    MacDonald, Paul S

    2007-01-01

    Francis Bacon offers two accounts of the nature and function of the human mind: one is a medical-physical account of the composition and operation of spirits specific to human beings, the other is a behavioral account of the character and activities of individual persons. The medical-physical account is a run-of-the-mill version of the late Renaissance model of elemental constituents and humoral temperaments. The other, less well-known, behavioral account represents an unusual position in early modern philosophy. This theory espouses a form of behavioral psychology according to which (a) supposed mental properties are "hidden forms" best described in dispositional terms, (b) the true character of an individual can be discovered in his observable behavior, and (c) an "informed" understanding of these properties permits the prediction and control of human behavior. Both of Bacon's theories of human nature fall under his general notion of systematic science: his medical-physical theory of vital spirits is theoretical natural philosophy and his behavioral theory of disposition and expression is operative natural philosophy. Because natural philosophy as a whole is "the inquiry of causes and the production of effects," knowledge of human nature falls under the same two-part definition. It is an inquisition of forms that pertains to the patterns of minute motions in the vital spirits and the production of effects that pertains both to the way these hidden motions produce behavioral effects and to the way in which a skillful agent is able to produce desired effects in other persons' behavior.

Their paper provides an overview in general education, in particular foreign language education, can be acknowledged as a lifelong learning process which can be transformed beyond the borders in global sense. Learning a foreign language requires proficiency in four basic skills which are reading, writing, speaking, and listening. Of these skills, speaking and listening are the most daunting tasks for learners and create obstacles when learners of target language do not get the chance of meeting native speakers. Such obstacles can be overwhelmed by integrating certain applications into education process. Service-learning through the internet as a teaching method can be considered one of the most striking one of those applications for foreign language learners.

Também para os novos paradigmas do turismo, como a preservação da natureza, a data é importante, pois marca a criação do Serviço de Parques Nacionais, nos Estados Unidos, em 1916, que servirá de modelo aos demais países do mundo. Precedida de tantas efemérides transcendentes, a nossa revista tem a responsabilidade de deixar para o futuro uma marca de qualidade acadêmica e inovação científica, que pretendemos cumprir apoiados nos excelentes pesquisadores que há no Brasil e nos países vizinhos, assim como aqueles consagrados no primeiro mundo que nos prestigiam com intercâmbios culturais há tantos anos. O primeiro número teve impressionante acolhida, tendo os editores recebido mails elogiosos de todo o país, assim como da Nova Zelândia, do México, da Espanha, da Argentina, entre outros, de cientistas provenientes das mais diversas áreas, refletindo o sucesso da nossa abordagem multidisciplinar sobre o turismo. Neste segundo número, apresentamos estudos inovadores referentes a aspectos simbólicos do turismo

Ti is the last issue of the year 2007. As you volume ( Number 3 was the special issue of TOJDE on “Web 2.0 and Social Software in Distance Education” subject. I received many congrulation for this special issue from the subject expert and TOJDE readers. During 6 months I received more than 45 submissions. Some of them rejected by me for the reason that their subjects were not fit for TOJDE’s publishing content strategy, and some of them rejected by TOJDE’s editors. And others can be publish next year’s issues In this issue we published one notes for Editor, 13 articles, already one review (maybe I can update for one or two reviews in due course which I am waiting from my book reviewers, news and announcements for our readers. This time 24 authors from eighth different countries are placed in this issue. These published articles are from Australia, Gana, Indonesia, Malaysia, Nigeria, Pakistan, Turkey, and UK. The first article of this issue is coming from Faculty of Education, Monash University, Victoria, AUSTRALIA. Article is entitled as “Globalization, Distance Education And Hegemonic Futures” and written by Dr. Glenn RUSSELL. He says in his paper that “Available options for distance educators can be understood in terms of instrumental and interpersonal axes that can potentially indicate the relative consideration that can be given to these factors. This approach is suggested as one way to understand available options at a time when there has been an apparent increase in instrumental approaches to distance education at the expense of interpersonal approaches and issues of social justice. While this problem is of concern, it is more appropriate to reflect on the unintended consequences of distance education for society and identify them than it is to uncritically oppose globalisation

According to the findings of the study, students needed to get support about education directives, career guidance, technical equipment, and personal problems. In this issue we published two book reviews. The first issue on “UNIVERSITY TEACHING IN FOCUS:A Learning-centred Approach” which is edited by Lynne HUNT and Denise CHALMERS and reviewed by S. K. PULIST from india. He empasises about the book that The book as the name depicts, focuses on different aspects of university teaching from learner-centred point of view. A wise range of issues has been highlighted and properly addressed by the authors in a very diligent manner. It will help the teachers in constructively engaging the students in effective learning. It is a step forward towards empowering the upcoming teachers with necessary strategies and stand point so that they are able to help the students in enhancing their quality learning. The book would be helpful not only to the novice teachers who have just stepped in the teaching profession but also other stakeholders of higher education system. 2nd book review is on “TRENDS AND ISSUES IN DISTANCE EDUCATION: International Perspectives, Second Edition”, edited by Lya Visser, Yusra Visser, Ray Amirault & Michael Simonson and Reviewed by Dr. Dilek ALTUNAY from Mustafa Kemal University, Hatay, TURKEY. She mentioned about the book that this book makes a contribution to the field of distance education by offering a comprehensive overview and analysis of the current trends and issues in distance education. In addition, the book is well-organized and coherent in terms of presentation. The reader is guided by section editors who provides introduction to the section and an overview of the chapters in the section, which makes the book reader-friendly.

    Francis Bacon (1561-1626) maintained a lifelong interest in the institutional implementation of experimental science. What changed over the years were the rhetorical strategies employed to give this project legitimacy. I systematize those changes by dividing Bacon's works into three groups according to three criteria: what rite of officialization is enacted in each text (e.g., conversion, fatherly generation, royal delegation); who the inscribed addressee is (e.g., an imagin...

    Directory of Open Access Journals (Sweden)

    Guill Katherine E

    2008-03-01

    Full Text Available Abstract Background With advances in DNA re-sequencing methods and Next-Generation parallel sequencing approaches, there has been a large increase in genomic efforts to define and analyze the sequence variability present among individuals within a species. For very polymorphic species such as maize, this has lead to a need for intuitive, user-friendly software that aids the biologist, often with naïve programming capability, in tracking, editing, displaying, and exporting multiple individual sequence alignments. To fill this need we have developed a novel DNA alignment editor. Results We have generated a nucleotide sequence alignment editor (DNAAlignEditor that provides an intuitive, user-friendly interface for manual editing of multiple sequence alignments with functions for input, editing, and output of sequence alignments. The color-coding of nucleotide identity and the display of associated quality score aids in the manual alignment editing process. DNAAlignEditor works as a client/server tool having two main components: a relational database that collects the processed alignments and a user interface connected to database through universal data access connectivity drivers. DNAAlignEditor can be used either as a stand-alone application or as a network application with multiple users concurrently connected. Conclusion We anticipate that this software will be of general interest to biologists and population genetics in editing DNA sequence alignments and analyzing natural sequence variation regardless of species, and will be particularly useful for manual alignment editing of sequences in species with high levels of polymorphism.

    2013-01-01

    Basic Common Data Format (CDF) tools (e.g., cdfedit) provide no specific support for creating International Solar-Terrestrial Physics/Space Physics Data Facility (ISTP/SPDF) standard files. While it is possible for someone who is familiar with the ISTP/SPDF metadata guidelines to create compliant files using just the basic tools, the process is error-prone and unreasonable for someone without ISTP/SPDF expertise. The key problem is the lack of a tool with specific support for creating files that comply with the ISTP/SPDF guidelines. There are basic CDF tools such as cdfedit and skeletoncdf for creating CDF files, but these have no specific support for creating ISTP/ SPDF compliant files. The SPDF ISTP CDF skeleton editor is a cross-platform, Java-based GUI editor program that allows someone with only a basic understanding of the ISTP/SPDF guidelines to easily create compliant files. The editor is a simple graphical user interface (GUI) application for creating and editing ISTP/SPDF guideline-compliant skeleton CDF files. The SPDF ISTP CDF skeleton editor consists of the following components: A swing-based Java GUI program, JavaHelp-based manual/ tutorial, Image/Icon files, and HTML Web page for distribution. The editor is available as a traditional Java desktop application as well as a Java Network Launching Protocol (JNLP) application. Once started, it functions like a typical Java GUI file editor application for creating/editing application-unique files.

  1. Francis Bacon and Magnetical Cosmology.

    Science.gov (United States)

    Wang, Xiaona

    2016-12-01

    A short-lived but important movement in seventeenth-century English natural philosophy—which scholars call “magnetical philosophy” or “magnetical cosmology”—sought to understand gravity (both terrestrial and celestial) by analogy with magnetism. The movement was clearly inspired by William Gilbert’s De magnete (1600) and culminated with Robert Hooke’s prefiguring of the universal principle of gravitation, which he personally communicated to Isaac Newton in 1679. But the magnetical cosmology, as professed by those in the movement, differed from Gilbert’s philosophy in highly significant ways. Proponents never accepted Gilbert’s animistic account of magnets and seem tacitly to have accepted a belief in action at a distance that Gilbert himself rejected. This essay argues that Francis Bacon (1561–1626) had already provided just the adaptations to Gilbert’s philosophy that the later thinkers adopted, including an important endorsement of action at a distance, and that he should be recognized as playing an important role in the movement.

  17. EDITORIAL: Editor's Farewell

    Hudson, R. P.

    1989-01-01

    The completion of Volume 26, 1989, marked the end of my tenure as Editor of Metrologia. My association with the journal, its parent body the Comité International des Poids et Mesures, its host organization the Bureau International des Poids et Mesures, the publishers Springer-Verlag and last (but by no means least) the Editorial Board, has been a pleasant one and I trust that the subscribers will have found the product to be generally satisfactory. There have been, it is true, some disappointments along the way and I shall mention two of these while expressing the hope that the new Editor will enjoy a greater success in their regard. First is the question of circulation, which has stayed dangerously low, although the shrinkage has tapered off in the most recent years. Because of the narrow public support, the costs of production are relatively high and this, through a consequently high subscription rate, tends to enshrine the unsatisfactory state of affairs. Modest schemes to broaden the journal's appeal and bring in a wider readership have foundered upon the first step, namely, that of procuring from staff members of the national standards laboratories the hoped-for articles which would discuss the state of the art in delivering the highest-quality measurement services to the public. However, some very interesting and bolder schemes are presently under discussion. I had also hoped to leaven the journal's content a little by regularly appearing articles on the latest developments within the great national laboratories. But, as with technical review articles, it has proven very difficult to find the right authors who can also spare the time, and only a few laboratories have found it possible to collaborate. In taking my leave, it remains for me to thank all the contributors, referees and readers for their support, to express the hope of an ever brighter future for Metrologia and to wish to the new Editor, Dr D A Blackburn, a happy and successful tenure.

The test program provided understanding of the heterogeneous erosion distribution of the prototype blades and quantitative data for comparison in subsequent tests on the model of the machine. Model tests and flow analysis were also performed, to detect cavitation on a Francis turbine model. The results are compared to those obtained on the prototype measurements. The model used for that study is built on the basis of a geometrical recovery of one of the most eroded blade of the prototype. Different methods were investigated to predict cavitation erosion on Francis turbines from model. They are based on measurement of pitting, pressure fluctuations and acceleration. The methods proposed are suitable to measure cavitation aggressiveness on model and on prototype, and that the level on the model is several orders of magnitude smaller than on the prototype.

    Full Text Available From the Editors Dear readers,We are happy to greet you with the August 2017 issue of our Journal. This issue contains two reports and five original articles. The title of the first report is “Roma Health in Edirne: Social Determinants of Health and Health Status”. In their report, Eskiocak et al. investigate the social determinants of health and their health related outcomes among the Roma communities living in Edirne. The second report deals with gender related issues. Doğan et al. investigate the effects of gender inequality on women's lives through a comparison of countries that do and do not implement policies based on gender equality.Original articles in this issue cover many important public health issues. The first, conducted by Koçak et al., investigates the type 2 diabetes risk of primary school teachers and their lifestyle behaviors. Results of the study show that 5.7% out of 975 primary school teachers have a high risk of type 2 diabetes.The second original article entitled “Unintended pregnancies, induced abortions and risk factors in women admitted to hospitals due to birth or abortion in Hatay” was based on a study of 635 women. The results of this study, done by Savaş et al., show an unintended pregnancy rate of 15%. It is further estimated that almost half of all induced abortions are reported as spontaneous abortions. The third article, which was written by Çam et al., is about the frequency of eating disorders in adolescents. This descriptive study, with the participation of 338 high school students, found the frequency of eating disorder attitudes to be 18.3% among the participants. In a descriptive study conducted by Emerce et al., the knowledge and practice of laboratory safety by laboratory analysts and technicians was investigated. It was found that all 93 laboratory workers who participated in the study have failed in some safety practices throughout their careers, and have been eager to get regular

    Full Text Available Teaching about globalizations and our interconnectedness with people and places around the world is an essential component of K-12 and higher education, but knowledge about global issues and news is not enough. Increased mobility, digital communication, and cultural hybridity, along with oppression and social injustice require that educators and students not only be able to communicate and collaborate with people different from them, but regularly engage in critical self-reflection around perceived norms and values. In January 2016, the editors of this special issue distributed a call for theoretical, research-based, and practitioner oriented manuscripts on teaching and learning that bring social studies and global citizenship education together. Evidence by the transnational contributions published within this issue of the Journal of Social Studies Education Research, the place of global citizenship education within the social studies is evolving, multifaceted, and not without complications. In short: just how it should be.

    Full Text Available On September 2017, two large earthquakes struck México. Numerous casualties and at least 40 buildings collapsed in Mexico City.   The earthquakes are explained by the tectonic setting of Central America, the Cocos plate subducts underneath the North American Plate at about 7-8 cm a year, making Mexico a seismically active region. But the two earthquakes - with hypocenter depths between 50 and 60 km – did not occur in the contact between the two tectonic plates as is usually expected, but rather within the Cocos plate as it bends downward within the mantle. Both events showed a normal faulting mechanism, and although they were widely felt, their major impact was in densely populated Mexico City, where wave amplification is expected due to the geological features of the City's soil structure.   We know that we cannot predict earthquakes, and although this is the holy-grail in seismology, it seems like we are not close to accurately predict them. Nevertheless, early warning systems have been developed in various places, including Mexico, and they were successful in issuing an alarm, although with a few seconds before the strong shaking. These developments can save lives and continue to be relevant and are likely to be implemented in other regions, including the pacific coast of the US. Another aspect that can save lives is people’s awareness. The M7.1 earthquake occurred in the afternoon of the anniversary of the 1985 Michoacan earthquake, just a couple of hours after an earthquake drill in Mexico City, so people had just recently been remained of what to do.  This most likely saved lives.   We should ask ourselves, are we prepared? Is our city prepared?     Germán Prieto Editor in Chief   Carlos A. Vargas Former Editor

    This last year being an odd numbered year, the pages of Nuclear Fusion saw a large influx of expanded papers from the 2012 Fusion Energy Conference in San Diego. Many papers have focused on the scientific and technical challenges posed by ITER. Contributions are steadily increasing from the new superconducting tokamaks in Asia. The ITER Project continues to move ahead. Construction at the Cadarache site is quite remarkable. Buildings completed include the huge Poloidal Field Coils Winding Facility and the Headquarters building, which has been occupied by the ITER staff. Work is progressing on the Assembly building and the Cryostat Workshop. The base of the tokamak complex is being laid. Besides the construction that is taking place and will take place at the site, components from around the world have to navigate the complex route from Marseilles to the site. A test convoy replicating the dimensions and weights of the most exceptional ITER loads successfully traversed that route in 2013. We are pleased to report that the IAEA and ITER have finalized the agreement for ITER authors to publish papers in Nuclear Fusion . Nuclear Fusion is proud to continue its key role in providing the leading forum for the documentation of scientific progress and exchange of research results internationally toward fusion energy. Refereeing The Nuclear Fusion editorial office appreciates greatly the effort made by our referees to sustain the high quality of the journal. Since January 2005, we have been offering the most active referees over the past year a personal subscription to Nuclear Fusion with electronic access for one year, free of charge. We have excluded our Board Members, Guest Editors of special editions and those referees who were already listed in previous years. The following people have been selected: J.M.

    . Their scheme is embedded in an experimental ATM network with the potential for guaranteed QoS. The system features QoS support mechanisms in both the network and the end systems. Of particular interest is reported experience with a dynamic QoS adaptation protocol implemented in the network and based on video scaling techniques and filtering. In summary, this special issue provides an up to date review of approaches to QoS management and their practical realization. Of course, no claim is made as to comprehensiveness, but the chosen papers do serve as a highly representative sample of current directions in QoS research. The editors are very much obliged to all authors, reviewers and publishers. Without their excellent work, and the contribution of their valuable time this special issue would not have been possible.

    Francis Perrin had a brilliant and rapid career. He was a strict and honest man. He had a fast intelligence, a huge knowledge, he was faithful. Finally his courtesy and his generosity had made of him an outstanding and model personality very little known because of his extreme discretion. He lived his professional career (1920-1970) with passion. He thought that science might be one mankind heritage. He worked in CEA and played a crucial role in the CERN creation. He was an accomplished scientist since he tackled the mathematics, physics, and even chemistry scope. 52 refs

    Full Text Available In 2001, the Natural History Museum of Barcelona remodelled its journal Miscel·lània Zoològica as Animal Biodiversity and Conservation. One of the aims of this change was to obtain an impact factor, the index that characterises the international ranking of journals. This milestone was reached some years later, in 2012, having published 291 articles that have been cited in impact journals 1,626 times. Two of these papers have been cited more than 100 times. We are now ready to take the next step forward. Our new challenge is to increase our impact factor so that Animal Biodiversity and Conservation is comparable with prestigious international journals in the field. To meet this objective we have assembled a team of editors with international recognition, and we will continue to expand this team over time. We have sought support from the most prestigious Spanish scientific societies and three have accepted the task: the Spanish Society of Ethology, the Spanish Association of Terrestrial Ecology, and the Spanish Society of Evolutionary Biology. These societies have named thematic editors who will help us strengthen their respective disciplines. This means that we will also expand the range of fields covered in the journal in future, interpreting the expression animal biodiversity in the journal´s title in its widest sense. Another front that we have opened to boost Animal Biodiversity and Conservation is the new webpage, remodelled for use as a medium to post our published papers. With this move we not only hope to improve our services to readers but also look towards open access, open access in its broadest conception, offering the journal to scientists, both readers and authors, free of charge. If we want science and the knowledge it generates —produced with public money— to belong to us all, we not only have to enable everyone to read it but we also have to help everyone publish, independently of their economic state.

    Full Text Available Letter from the editor Our first issue of 2018 is available now. We have 9 articles in this issue, in topics ranging from soil characterization, petrophysical properties of rocks, signal processing of images and GNSS station to asteroid impact effects. Mechanical soil properties in sandy-pebble soil are studied as a function of grain size content in Lu et al. Satellite-derived soil moisture estimation is discussed in Thanabalan and Vidhya, based on a semi-empirical approach and backscattering images. Macroscopic mechanical characteristics of rocks depend on a number of factors, including microstructure damage. Under changing temperature conditions (freeze-thaw rock samples studied by Jiang show significant strength decrease, which has important consequences in engineering. Advanced signal processing methods are used in Zeng et al. for image retrieval applied to remote sensing data, using a Bayesian network approach. Similarly, Oktar and Erdogan use linear trend and wavelet analysis to continuous GNSS data showing both displacements due to tectonic as well as atmospheric and hydrologic effects. Debris flows can in some cases become serious hazards because they can block river flow as a debris flow dam. Chen et al. propose a method to identify the formation of such dams, with an example from the Er river in Taiwan. Mamaseni et al. study the petrophysical properties of three formations in the Duhok Basin, northern Iran, based on well-log data. Results suggest a significant thickness with good moveable hydrocarbons in the study area. Methane adsorption and gas content are strongly influenced by shale composition. Zhu et al. show that Total Organic Content has a stronger influence on methane adsorption and gas content than the mineral composition, studying samples from the southern Sichuan Basin. Our last contribution in this issue discussed a large asteroid impact in eastern Colombia. The impact would have affected the environment and landscape, but

    The variable demand on the energy market requires great flexibility in operating hydraulic turbines. Therefore, turbines are frequently operated over an extended range of regimes. Francis turbines operating at partial load present pressure fluctuations due to the vortex rope in the draft tube cone. This phenomenon generates strong vibrations and noise that may produce failures on the mechanical elements of the machine. This paper presents the failure analysis of a broken Francis turbine runner blade. The failure appeared some months after the welding repair work realized in situ on fatigue cracks initiated near to the trailing edge at the junction with the crown, where stress concentration occurs. In order to determine the causes that led to the fracture of the runner blade, the metallographic investigations on a sample obtained from the blade is carried out. The metallographic investigations included macroscopic and microscopic examinations, both performed with light and scanning electron microscopy, as well as EDX - analyses. These investigations led to the conclusion, that the cracking of the blade was caused by fatigue, initiated by the surface unevenness of the welding seam. The failure was accelerated by the hydrogen embrittlement of the filling material, which appeared as a consequence of improper welding conditions. In addition to the metallographic investigations, numerical computations with finite element analysis are performed in order to evaluate the deformation and stress distribution on blade.

    Not only was Sir Francis Galton a famous geographer and statistician, he also invented "eugenics" in 1883. Eugenics, defined as the science of improving racial stock, was developed from a new heredity theory, conceived by Galton himself, and from the evolution theory of Charles Darwin, transposed to human society by Herbert Spencer. Galton's eugenics was a program to artificially produce a better human race through regulating marriage and thus procreation. Galton put particular emphasis on "positive eugenics", aimed at encouraging the physically and mentally superior members of the population to choose partners with similar traits. In 1904, he presented his ideas in front of a vast audience of physicians and scientists in London. His widely-publicized lecture served as the starting point for the development of eugenics groups in Europe and the United States during the first half of the 20th century.

    Full Text Available Déjàvu,or better,déjà écouté is an appropriate expression to describe an audition of certain works by Francis Poulenc (1899-1963. A sui-generis character in 20th century music, Poulenc has questioned the whole heritage that came before him, French or not, according to the premises of the group he belonged to, Les Six, although not always reaching similar results. His main concern was to make good music, an ideal not far from that of Debussy, “music should humbly seek to please” (Harry Halbreich. This article approaches the use of quotation and other processes of allusion in the works by Poulenc, as seen in his voice and piano mélodies cycle La fraîcheur et le feu, identifying thematic, melodic, and harmonic, origins used coherently in several pieces. and helping to solidly build his musical language.

    It is hard to believe but Clinical and Investigative Medicine (CIM), the official journal of Canadian Society for Clinical Investigation (CSCI), will soon celebrate its 40th birthday!  Over these past four decades, CIM has been the premier journal for Canadian clinician scientists; publishing over 1,000 articles on breakthroughs and major advances from Canada and around the world.  We are listed on Medline, PubMed and the Library of Science. We have been, and will continue to be, an independent journal. To celebrate this auspicious occasion, we have plans to become an even bigger showpiece for national and international clinical advances. We want to connect more closely with Canadian clinician scientists and trainees and we particularly want to encourage more Canadian publications. Changes will soon be coming to CIM with several new features: Newsletter with announcements and news on activities of interest to clinician scientists and trainees; Focused Reviews on specific areas of research; Reflections on work and life experiences of trainees and senior clinician scientists; Methods Papers describing novel methods anticipated to be useful for others; and  Guidelines or Recommendations on clinical care that are endorsed by a Canadian Medical or Surgical Society. Starting in 2018, we will be publishing on a quarterly basis. This will help to ensure we will focus on important breakthroughs and commentaries. However, we are also planning a special edition in the autumn to commemorate the 40th birthday. Stay tuned! Of course CIM will continue to publish original papers on discoveries in pathophysiology, prevention, management, treatment and outcome of clinical problems confronting clinicians in Canada and around the world.  Please join us as we embark on these changes and a new era for CIM, Robert Bortolussi Clinical and Investigative Medicine (CIM) Editor in Chief.

    ısı” (Social Studies Teachers’ Perceptions of Tolerance and Feryal Çubukçu “Values Education Through Literary Texts”. These valuable papers have potential to contribute the literature on social studies education. One of the main aims of ASSE was to establish a regular scientific event through which social studies educators from Turkey and abroad get together to share their academic works and ideas. In conjunction with the Faculty of Education of Bolu Abant Izzet Baysal University we are organizing the Fourth International Symposium on Social Studies Education (ISSE in April 2015. The main theme of ISSE the 4th is “Peace Education”. The preference of this theme emphasizes on our hopes and determination for our envision for peace in the late Ottoman geography, in which guns have still been on fire and people have still been shedding tears. And this could be regarded as something similar to the action of Mustafa Kemal Pasha who thought of about the reconstruction of the country after the war and assembled an “Educational Congress” in Ankara to discuss educational issues, during the most difficult days of the War of Independence in 1921. Adopting this approach, we have been considering putting effort to institutionalize the values of democracy, human rights, justice, freedom of thought and freedom of conscience. As a final remark, I would like to thank everyone who contributed to the production of this issue and special thanks to Assoc. Prof. Dr. Erkan Dinç who acted as issue editor. Best regards and hope to meet you in ISSE the 4th…

D. (chief and executive editor of the journal Thermal Science and professor Milan Radovanović, Ph. D. (president of the Society of Thermal Engineers of Serbia. Gratitude that we have is not only for their effort as researchers and creative and challenging education, but also for the founding and guidance of Thermal Science, today internationally known and appreciated science journal. This long term editing work that professor Oka and professor Radovanović nurse within the Society of Thermal Engineers of Serbia became window to world for Serbian researchers. Publishing the scientific article in the journal Thermal Science today is not only the major research event for domestic scientists but for the researchers all over the world. About excellent science and nurture characters of professor Oka and professor Radovanović is saying a lot the decision to dedicate this special issue of the journal Thermal Science to fifty anniversary of Faculty of Mechanical Engineering in Kragujevac. This decision was greeted by the employees of MFKG as a special and dear acknowledgment for their effort during fifty years long research work.

In their notes they mentioned that Students register the device on the company Web site, and the instructor synchronizes the database in order to know which students have registered devices, thus creating accountability for “quizzes” in class. During the lecture, students “vote” for multiple choice answers on screen, and real-time results are displayed (anonymously after the polling is finished, providing instant formative feedback. Another model is for a department or institution to purchase clickers and make available in the classroom. Students pick up the clicker as they enter the room each day and replace when exiting. Using this approach does not allow for direct accountability, unless students are registered to a specific number on the clicker, which is documented and tracked.

They focused on Simply including a narrative component may provide enough creative ammunition for students to feel that a particular assignment can be more interesting (Clark 2010, if their work is to be wrapped around a narrative format, such as a short story in favor of an essay or formal writing. But there are numerous free technology tools available today that take the process one step further, by injecting different editing options and high-end production values. Students do not merely assemble a story in words. They can now do it primarily with images, and many of the slideshow services online allow for text captions, dynamic transitions, special effects, and relevant animations. Students become videographers and directors as much as they function as storytellers. The slideshow builders thus do a better job than “old fashioned” essay/short story assignments at meeting the need of 21st century students, many of whom arrive at institutions of higher learning with at least an already-ingrained interest in such tools, if not explicit experience.The following note is that a review of existing literature pertaining to servant leadership and faculty development.

    the role of universities as content producers for credentialed learning to be questioned, prompting many educators to explore new ways of supporting online learning. The sixth article from Palitha Edirisingha (UK, Chiara Rizzi (Italy, Ming Nie (UK and Libby Rothwell (UK report on a study involving the use of podcasting (Curry, 2004 to provide teaching and learning support for an undergraduate module on English Language and Communication. The findings led to development of a model for integrating podcasts in on-campus blended learning, and which can have potential applications in distance learning contexts. The model is based on three main features of podcasts identified as facilitating student learning: learner choice and flexibility offered by podcasts; tacit knowledge and experience of peers conveyed in discussions; and a sense of informality brought into formal learning. Also from the implementation perspective, Penny de Byl and Janet Taylor (Australia describe a Web 2.0/Web3D hybrid e-learning platform, called the AliveX3D platform, which involves the application of the Web 2.0 ethos to an online 3D virtual environment. The platform and accompanying tools are designed to enable the creation of authentic learning experiences with a large degree of learner control, and to promote collaborative dialogue between learners. The immersion in the 3D worlds enables learners to negotiate meaning based on their own personal cognitive, affective and kinaesthetic experiences rather than relying merely on descriptions of others’ experiences. Last but not least, the “Notes to the Editor” section contains a contribution from Yavuz Akbulut and Mübin Kiyici (Turkey, on the instructional uses of blogs. And two book reviews from the field. We hope you enjoy reading this contributions, and welcome your feedback, rejoinders and reflections on the various articles contained within this special issue. Mark J. W. LEE and Hakan G.

These published articles are arrived to the TOJDE from Australia, Guyana, India, Indonesia, Iran, Malaysia, Nigeria, Russia, Taiwan, Turkey, USA and Zimba bwe. First all, you should know that if a submission picks up from three TOJDE editors between 4.5 and 9 over all 9 credits, it means that this submission can be published in TOJDE in the coming issue. However, since the publishing priority of the accepted papers belongs to the highest scored ones, submissions which receive a score between 4.5 and 5 or 6 may wait and be archived for publishing later on. TOJDE administration respected this publishing rule up to now. Therefore, some accepted submissions which obtained over 4.5 have not been published up to now. Some of these submissions were waiting for publishing in TOJDE in the future sice 2011. In this issue, we decided to give them a chance to be published. For this reason that becoming end of the year of 2012, more papers for this issue included me than the previous issues. The 1st article arrived from Nigeria and written by Sunday O. ADEGBESAN, from Training and Research Fellow, National Institute for Educational Planning and Administration (NIEPA, on “Effect Of Principals’ Leadership Style On Teachers’ Attitude To Work In Ogun State Secondary Schools, Nigeria ".

It is mentioned in their article that as a new member of the mega-Universities, Bangladesh Open University (BOU introduced with an example a course team approach for developing effective course materials for distance students. BOU teaching media includes such as printed course books, study guides, radio and television broadcasts, audiocassettes and occasional face-to-face tutorials. Each course team comprises specialist course writer(s, editor, trained style editor, graphic designer, illustrator, audio-visual producer and anonymous referees. An editorial board or preview committee is responsible for the final approval for publishing or broadcasting materials for learners. This approach has been proved to be effective, but appeared to be complicated and time-consuming. This report focuses on the quality and processes of BOU course materials development taking into account the strengths and weaknesses of the current approach.

    Full Text Available A partir da perspectiva psicanalítica, a autora aborda a obra de Francis Bacon se utilizando de uma concepção estética que a reconhece como uma realidade ontológica. Dessa forma, considera que como obra de arte, são seus próprios elementos constitutivos, numa tensão interna, que são capazes de provocar efeitos ou as sensações que são o seu objetivo último conforme defendia Bacon. Em sua análise a autora examina e discute a dialética “tempo - espaço”, revelada pelo poeta pintor, como sendo de especial interesse para a clínica psicanalítica na medida em que esclarece importantes questões relativas ao Real como impossível, tal como o compreendeu Lacan. A pintura de Bacon examinada como referência à “sublimação criacionista da pulsão de morte” permite, segundo a autora, vislumbrarmos o para além da cadeia significante. Conclui que a arte, assim como a clínica psicanalítica, supõe deslocamentos subjetivos que implicam corte - rompimento com a tendência unificadora e pacificadora de Eros.

    , Bogazici University, Istanbul,TURKEY. This paper examines the emerging ideas to implement the usage of Second Life as an educational tool in a wide range of subject areas. The majority of the information used to create these 10 pedagogical approaches was derived from a series of participative inquiries, personal observations, formal and informal interviews, and documenting the perceptions of teachers and students using (and trying to use Second Life as an educational tool. Ten pedagogical approaches have emerged thus far. Each section briefing explains the concept, illustrates the idea with examples, and provides implementation suggestions.

This study reviewed empirical research conducted in Second Life by educators since Second Life’s launch in 2003. The study’s purpose was to identify how Second Life is being used in both K-12 and higher education. The methodology, findings, and recommendations of 27 research studies were analyzed. Researchers identified potential problems when using Second Life in education, including issues with the Second Life software and hardware requirements, a steep learning curve, and the possibility of students becoming exposed to distractions or inappropriate content.

He emphasizes that while in the teaching process they use both synchronous and asynchronous presentation technologies; in order to support course content they use e-mail, web, cd, and course book technologies to provide basic learning environment function; they prefer different environments to cover face to face education needs; they take self learning and collaboration as basis and they take projects and term paper evaluations serious; they mostly prefer multiple choice tests and they usually make virtual courses exams through the internet. Regarding the characteristics of their institutions’ applications, the study group have agreed on mostly to connection and being dependent on connection opportunities. A significant difference between their institutions’ characteristics and the model for developing computer labs, when they had started to provide virtual lessons and presentation technologies used has been found.The first article of this issue is coming from Hellenic Open University, GREECE which is written by Paraskevi VASSALA.

  10. Measurement of pressure pulsations in Francis turbines

    Energy Technology Data Exchange (ETDEWEB)

    Kobro, Einar

    2010-11-15

    The work presented in this thesis involves preparation and execution of measurements on Francis runners. The measurements were performed by means of onboard measuring equipment both in model runners and full-scale prototype runners. Also, analysis of the measured data, and the discussion of the results, is presented. The measurements resulted in large data sets. These data sets were used by the author to investigate the dynamic pressure and strain in the runners. The results of the analysis can be used as input in future turbine design. Andritz Hydro AG has used the data for verification of their numerical simulation tools. In connection with the refurbishment of Tokke power plant, two model runners were made available for onboard pressure measurements. To investigate the dynamic pressure in these runners, methods for integration of pressure transducers in the runner blades needed to be developed. After initial difficulties during the preparation, successful measurements were obtained from both model runners. At Tokke power plant, both the original and replacement runners were made accessible for onboard pressure and strain gauge measurements. On the original Kvaerner Brug AS runner, the test was prepared and performed by the author. This test failed, due to water intrusion in the logging chain. The second test was performed on the Andritz Hydro AG replacement runner. This test was prepared and performed by the author in close cooperation with Andritz Hydro AG, and the results were successful. The analysis results from both model and prototype runners show that the wake leaving the guide vanes is the most severe source of dynamic pressure in the runner. The draft tube vortex rope pulsation propagates upstream the runner, but does not appear as a significant frequency in the runner strain measurements. (Author)

    Full Text Available This issue our guest editors are close to home. Wilhelm Heitmeyer and Steven F. Messner, both members of our own Board of Editors, have assembled a focus section examining the question of “Youth at Risk.” Their collection certainly lives up to our aspiration to be truly interdisciplinary and international. The methods applied in the reported research range from interview-based studies through empirical number-crunching to laboratory experiments (the latter a first for this journal; the geographical scope spans from Argentina through Central America and Europe to Africa. The youth at risk here are in conflict with the police, with each other, with societies that fear them, with societies that ignore their needs. Our systematically eclectic approach continues outside the focus section too, with contributions on the theory of violence, female fighters in Africa, and spousal violence in Pakistan.

  15. Numerical Study of a High Head Francis Turbine with Measurements from the Francis-99 Project

    2015-01-01

    For the Francis-99 project initiated by the Norwegian University of Science and Technology (NTNU, Norway) and the Luleå University of Technology (LTU, Sweden) numerical flow simulation has been performed and the results compared to experimentally obtained data. The full machine including spiral casing, stay vanes, guide vanes, runner and draft tube was simulated transient for three operating points defined by the Francis-99 organisers. Two sets of results were created with differing time steps. Additionally, a reduced domain was simulated in a stationary manner to create a complete cut along constant prototype head and constant prototype discharge. The efficiency values and shape of the curves have been investigated and compared to the experimental data. Special attention has been given to rotor stator interaction (RSI). Signals from several probes and their counterpart in the simulation have been processed to evaluate the pressure fluctuations occurring due to the RSI. The direct comparison of the hydraulic efficiency obtained by the full machine simulation compared to the experimental data showed no improvement when using a 1° time step compared to a coarser 2° time step. At the BEP the 2° time step even showed a slightly better result with an absolute deviation 1.08% compared with 1.24% for the 1° time step. At the other two operating points the simulation results were practically identical but fell short of predicting the measured values. The RSI evaluation was done using the results of the 2° time step simulation, which proved to be an adequate setting to reproduce pressure signals with peaks at the correct frequencies. The simulation results showed the highest amplitudes in the vaneless space at the BEP operating point at a location different from the probe measurements available. This implies that not only the radial distance, but the shape of the vaneless space influences the RSI

    A few years ago, Francis Crick's son told me a story that I can't get out of my mind. I had contacted Michael Crick by email while digging through the background of the researchers who had cracked the genetic code in the 1960s. Francis had died in 2004, and I was contacting some of the people who knew him when he was struggling to decipher the code. Francis didn't appear to struggle often - he is known mostly for his successes - and, as it turns out, this one well-known struggle may have had a clue sitting just barely out of sight.

  3. Master equation and runaway speed of the Francis turbine

    Science.gov (United States)

    Zhang, Zh.

    2018-04-01

    The master equation of the Francis turbine is derived based on the combination of the angular momentum (Euler) and the energy laws. It relates the geometrical design of the impeller and the regulation settings (guide vane angle and rotational speed) to the discharge and the power output. The master equation, thus, enables the complete characteristics of a given Francis turbine to be easily computed. While applying the energy law, both the shock loss at the impeller inlet and the swirling loss at the impeller exit are taken into account. These are main losses which occur at both the partial load and the overloads and, thus, dominantly influence the characteristics of the Francis turbine. They also totally govern the discharge of the water through the impeller when the impeller is found in the standstill. The computations have been performed for the discharge, the hydraulic torque and the hydraulic efficiency. They were also compared with the available measurements on a model turbine. Excellent agreement has been achieved. The computations also enable the runaway speed of the Francis turbine and the related discharge to be determined as a function of the setting angle of the guide vanes.

Popular on Unix and Linux, it has a growing following on Windows systems, too. Most experienced system administrators cite vi as their tool of choice.

    As usual, being an even year, the 23rd IAEA Fusion Energy Conference took place at Daejeon, Korea. The event was notable not just for the quality of the presentations but also for the spectacular opening ceremony, in the presence of the Prime Minister, Kim Hwang-sik. The Prime Minister affirmed the importance of research into fusion energy research and pledged support for ITER. Such political visibility is good news, of course, but it brings with it the obligation to perform. Fortunately, good performance was much in evidence in the papers presented at the conference, of which a significant proportion contain 'ITER' in the title. Given this importance of ITER and the undertaking by the Nuclear Fusion journal to publish papers associated with Fusion Energy Conference presentations, the Nuclear Fusion Editorial Board has decided to adopt a simplified journal scope that encompasses technology papers more naturally. The scope is available from http://iopscience.iop.org/0029-5515/page/Journal%20information but is reproduced here for clarity: Nuclear Fusion publishes articles making significant advances to the field of controlled thermonuclear fusion. The journal scope includes: the production, heating and confinement of high temperature plasmas; the physical properties of such plasmas; the experimental or theoretical methods of exploring or explaining them; fusion reactor physics; reactor concepts; fusion technologies. The key to scope acceptability is now '....significant advances....' rather than any particular area of controlled thermonuclear fusion research. It is hoped that this will make scope decisions easier for the Nuclear Fusion office, the referees and the Editor.The Nuclear Fusion journal has continued to make an important contribution to the research programme and has maintained its position as the leading journal in the field. This is underlined by the fact that Nuclear Fusion has received an impact factor of 4.270, as listed in ISI's 2009 Science Citation

    The first record of water wheels dates back to ancient Greece. Over the next several centuries the technology spread all over the world. The process of arriving at the design of the modern Francis runner lasted from 1848 to approximately 1920. Though the modern Francis runner has little resemblance to the original turbines designed by James B. Francis in 1848, it became know as the Francis turbine around 1920, in honor of his many contributions to hydraulic engineering analysis and design. The modern Francis turbine is the most widely used turbine design today, particularly for medium head and large flow rate situations, and can achieve over 95% efficiency

    Marusić, M; Marusić, A

    2001-04-01

    There may be valuable research going on in the developing and financially less-privileged countries, but it usually does not reach international visibility, in spite of a large number of scientific journals in these countries. Such journals are not only invisible but, by perpetuating a vicious circle of inadequacy, may be directly damaging to the local science and research culture. We call for an international action to help journal editors in less privileged countries. International associations of editors may be leaders of these activities by defining, promoting, and perhaps controlling good editorial practice, as a main criterion for international recognition of a journal. However, the editors of small journals have the power and moral obligation to become a stronghold of quality and advancement in their scientific community. Their educational "tools" are editorial integrity and author-friendly policy. Editors can teach the authors study design, statistical analysis, precision, punctuality, research integrity, style and format of writing, and other aspects of scientific communication. The editors of "big", mainstream scientific journals can act as global educators, teaching and providing guidance to editors of small journals. The editors from developed countries as leaders, and editors from less advantageous environments as teachers are the key figures in shaping research communication in less privileged scientific communities.

  15. Francis Bacon: The Real's Brutality. The Figure and the Other

    Directory of Open Access Journals (Sweden)

    Guido Mannucci

    2014-03-01

    Full Text Available Getting in front of painting by Francis Bacon touches you deeply. I’m talking about aesthetics, sensations: resounding flow that strikes abruptly, making futile any search for meaning. Francis Bacon circumvents the figurative, the meaning, he aims to the figural: to feelings, not words. Beauty, in his paintings, shows itself in the peaceful union of the positive and of its contrary; if the negative wasn’t there, though, his paintings wouldn’t exude such a brutal sense of reality. This essay investigates the figure of Francis Bacon and the spectator – the Other – as he tries to confront the painting. Bacon will be analysed using a purely phenomenological approach, with references that range from Merleau-Ponty to Martin Heidegger; the meeting-collision between the spectator and the painting, instead, will be examined taking inspiration from the Winnicott’s thesis on the relationship between Bacon and mirrors in the painter’s childhood. In order to take distance from Winnicott’s psychoanalytical approach, this essay will focus on the relationship between spectator and painting from a more anthropological point of view.

    Traditionally, hydro power plants have been operated close to best efficiency point, the more stable operating condition for which they have been designed. However, because of changes in the electricity market, many hydro power plants operators wish to operate their machines differently to fulfil those new market needs. New operating conditions can include whole range operation, many start/stops, extensive low load operation, synchronous condenser mode and power/frequency regulation. Many of these new operating conditions may impose more severe fatigue damage than the traditional base load operation close to best efficiency point. Under these conditions, the fatigue life of the runner may be significantly reduced and reparation or replacement cost might occur sooner than expected. In order to design reliable Francis runners for those new challenging operating scenarios, Andritz Hydro has developed various proprietary tools and design rules. These are used within Andritz Hydro to design mechanically robust Francis runners for the operating scenarios fulfilling customer's specifications. To estimate residual life under different operating scenarios of an existing runner designed years ago for best efficiency base load operation, Andritz Hydro's design rules and tools would necessarily lead to conservative results. While the geometry of a new runner can be modified to fulfil all conservative mechanical design rules, the predicted fatigue life of an existing runner under off-design operating conditions may appear rather short because of the conservative safety factor included in the calculations. The most precise and reliable way to calculate residual life of an existing runner under different operating scenarios is to perform a strain gauge measurement campaign on the runner. This paper presents the runner strain gage measurement campaign of a mid-head Francis turbine over all the operating conditions available during the test, the analysis of the measurement signals

    Among a high number of Francis turbine references all over the world, covering the whole market range of heads, Alstom has especially been involved in the development and equipment of the largest power plants in the world : Three Gorges (China -32×767 MW - 61 to 113 m), Itaipu (Brazil- 20x750 MW - 98.7m to 127m) and Xiangjiaba (China - 8x812 MW - 82.5m to 113.6m - in erection). Many new projects are under study to equip new power plants with Francis turbines in order to answer an increasing demand of renewable energy. In this context, Alstom Hydro is carrying out many developments to answer those needs, especially for jumbo units such the planned 1GW type units in China. The turbine design for such units requires specific care by using the state of the art in computation methods and the latest technologies in model testing as well as the maximum feedback from operation of Jumbo plants already in operation. We present in this paper how a large Francis turbine can be designed using specific design methods, including the global and local optimization methods. The design of the spiral case, the tandem cascade profiles, the runner and the draft tube are designed with optimization loops involving a blade design tool, an automatic meshing software and a Navier-Stokes solver, piloted by a genetic algorithm. These automated optimization methods, presented in different papers over the last decade, are nowadays widely used, thanks to the growing computation capacity of the HPC clusters: the intensive use of such optimization methods at the turbine design stage allows to reach very high level of performances, while the hydraulic flow characteristics are carefully studied over the whole water passage to avoid any unexpected hydraulic phenomena.

    The editors of Revista Clínica Española(Rev Clin Esp) inform on their editorial activity during the last 12 months: (a) objectives and attainments, (b) editorial activity, and (c) objectives for 2014. In 2013 the most relevant modification concerning the editorial activity has been the translation into English of the 5 manuscripts with abstract contained in each issue (http://www.revclinesp.es/). From the first January to the 30th September 2013 we received 458 manuscripts (50.9 manuscripts per month), a similar figure to that obtained in 2012 (51.1 manuscripts per month). The acceptance rate of the 443 manuscripts whose editorial process has been concluded was 23.7% (originals, 11.8%). We asked for 253 revisions to 186 reviewers and we received 74.4% revisions in less than 2 weeks (10.9 days). The mean time to adopt an editorial decision for all manuscripts («accepted»/«rejected») has been 20,3 (half than in 2009). For «originals» this figure has dropped from 56.6 days in 2009 to 22.5 days in 2013. The mean time elapsed from manuscript reception to its on-line publication was 94.8 days in 2013 (110.5 in 2012 and 155.8 in 2011). In 2013 the collaboration with the working groups from the Internal Medicine Spanish Foundation has reported 17 published manuscripts. In 2013 we were informed that the Journal Citation Reports excluded Rev Clin Esp from its impact factor journal list due to its elevated self-citations. We have taken a number of actions to reduce self-citations and we expect to be a minority in 2014. Some other data concerning the editorial policy are encouraging. In this sense, manuscript citation to Rev Clin Esp published articles has seen a substantial increase from 19% in 2008 to 29% in 2012. We work to achieve the digitalization of Rev Clin Esp from 1940 to 1999 (the journal is already digitalized since 2000). The continuous renewal of the journal sections and the working groups collaboration are necessary elements to make our journal, each day

    2012-01-01

    To assess the life expectancy of hydraulic turbines, it is essential to obtain the loading on the blades, especially during transient operations known to be the most damaging. This paper presents a simplified CFD setup to model the startup phase of a Francis turbine while it goes from rest to speed no-load condition. The fluid domain included one distributor sector coupled with one runner passage. The guide vane motion and change in the angular velocity were included in a commercial code with user functions. Comparisons between numerical results and measurements acquired on a full-size turbine showed that most of the flow physics occurring during startup were captured.

    The energy loss in hydraulic turbine is the most direct factor that affects the efficiency of the hydraulic turbine. Based on the analysis theory of inner energy loss of hydraulic turbine, combining the measurement data of the Francis-99, this paper calculates characteristic parameters of inner energy loss of the hydraulic turbine, and establishes the calculation model of the hydraulic turbine power. Taken the start-up test conditions given by Francis-99 as case, characteristics of the inner energy of the hydraulic turbine in transient and transformation law are researched. Further, analyzing mechanical friction in hydraulic turbine, we think that main ingredients of mechanical friction loss is the rotation friction loss between rotating runner and water body, and defined as the inner mechanical friction loss. The calculation method of the inner mechanical friction loss is given roughly. Our purpose is that explore and research the method and way increasing transformation efficiency of water flow by means of analysis energy losses in hydraulic turbine.

  8. The green roof dilemma - discussion of Francis and Lorimer (2011).

    2012-08-15

    Urban ecosystems are the most complex mosaics of vegetative land cover that can be found. In a recent paper, Francis and Lorimer (2011) evaluated the reconciliation potential of living roofs and walls. For these authors, these two techniques for habitat improvement have strong potential for urban reconciliation ecology. However they have some ecological and societal limitations such as the physical extreme environmental characteristics, the monetary investment and the cultural perceptions of urban nature. We are interested in their results and support their conclusions. However, for a considerable time, green roofs have been designed to provide urban greenery for buildings and the green roof market has only focused on extensive roof at a restricted scale within cities. Thus, we have strong doubts about the relevance of their use as possible integrated elements of the network. Furthermore, without dynamic progress in research and the implementation of well-thought-out policies, what will be the real capital gain from green roofs with respect to land-use complementation in cities? If we agree with Francis and Lorimer (2011) considering that urban reconciliation ecology between nature and citizens is a current major challenge, then "adaptive collaborative management" is a fundamental requirement.

  9. LDA measurements in the Francis-99 draft tube cone

    2014-01-01

    Velocity measurements were performed in the draft tube cone of a 1:5.1 scaled model of the Tokke hydropower plant, Norway; also known as the Francis-99 model. Results from the laser Doppler anemometry measurements undertaken at three operating points will be used as validation data for an upcoming workshop on the state of the art of Francis turbine numerical simulation. With the turbine operating at the best efficiency point, a sensitivity analysis of the flow parameters head, flow rate and runner rotational speed shows that the effects on the dimensionless velocity profiles are small as long as n ED and Q ED are held constant. The results indicate a well-functioning turbine at the best efficiency point and high load. At the part load operating point, a vortex breakdown occurs which distorts the velocity profiles and significantly lowers the turbine's hydraulic efficiency. Frequency spectrums of each LDA signal at part load reveals a peak which is asynchronous to that of the runner angular speed. The peaks might be related to the precession of a rotating vortex rope but the characteristics of the LDA signals are different compared to previous studies involving rotating vortex ropes

  10. The Second Christ, Saint Francis of Assisi and ecological consciousness

    Full Text Available Even though the life stories of Jesus and the so-called second Christ, Francis of Assisi, incline to the fantastical, their value for a modern ecological consciousness is defendable. Behind Francis� personification of nature and his mystical experiences of nature lie an intuitive sense of interconnectedness and interdependence, of being fully part of the natural web of life (confirmed by empirical science. The same is true of the immanence of Jesus. Religious figures like Francis and Jesus can provide a sound moral attitude towards caring for the natural world, but attitudes need to be informed by scientific knowledge to act ecologically correct. A partnership between attitudes and knowledge hopefully contains good news for a sustainable �green� planet.Intradisciplinary and/or�interdisciplinary�implications: Ecological hermeneutics (part of liberation theology or hermeneutics challenges traditional theologies� often anthropocentric bias in the intra-disciplinary arena. It respects the interconnectedness or interdependence of human and non-human life, including the non-organic, empirically substantiated by natural science. This shared realisation allows for a fruitful inter-disciplinary discourse with science to address the global ecological crisis.

  11. Effect of Guide Vane Clearance Gap on Francis Turbine Performance

    Directory of Open Access Journals (Sweden)

    Ravi Koirala

    2016-04-01

    Full Text Available Francis turbine guide vanes have pivoted support with external control mechanism, for conversion of pressure to kinetic energy and to direct them to runner vanes. This movement along the support is dependent on variation of load and flow (operating conditions. Small clearance gaps between facing plates and the upper and lower guide vane tips are available to aid this movement, through which leakage flow occurs. This secondary flow disturbs the main flow stream, resulting performance loss. Additionally, these increased horseshoe vortex, in presence of sand, when crosses through the gaps, both the surfaces are eroded. This causes further serious effect on performance and structural property by increasing gaps. This paper discusses the observation of the severity in hydropower plants and effect of clearance gaps on general performance of the Francis turbine through computational methods. It also relates the primary result with the empirical relation for leakage flow prediction. Additionally, a possible method to computationally estimate thickness depletion has also been presented. With increasing clearance gap, leakage increases, which lowers energy conversion and turbine efficiency along with larger secondary vortex.

  16. Francis Bacon: constructing natural histories of the invisible.

    Science.gov (United States)

    Rusu, Doina-Cristina

    2012-01-01

    The natural histories contained in Francis Bacon's Historia naturalis et experimentalis seem to differ from the model presented in De augmentis scientiarum and the Descriptio globi intellectualis in that they are focused on the defining properties of matter, its primary schematisms and the spirits. In this respect, they are highly speculative. In this paper I aim to describe the Historia naturalis et experimentalis as a text about matter theory, the histories of which are ascending from what is most evident to the senses to what is least accessible to them. Moreover, the Latin natural histories are parts of a methodological procedure in which the provisional rules and axioms obtained in one history can be used as theoretical assumptions for another history, thereby permitting one to delve ever more profoundly into the structure of nature.

  17. The "Visual Shock" of Francis Bacon: an essay in neuroesthetics.

    Science.gov (United States)

    Zeki, Semir; Ishizu, Tomohiro

    2013-01-01

    In this paper we discuss the work of Francis Bacon in the context of his declared aim of giving a "visual shock."We explore what this means in terms of brain activity and what insights into the brain's visual perceptive system his work gives. We do so especially with reference to the representation of faces and bodies in the human visual brain. We discuss the evidence that shows that both these categories of stimuli have a very privileged status in visual perception, compared to the perception of other stimuli, including man-made artifacts such as houses, chairs, and cars. We show that viewing stimuli that depart significantly from a normal representation of faces and bodies entails a significant difference in the pattern of brain activation. We argue that Bacon succeeded in delivering his "visual shock" because he subverted the normal neural representation of faces and bodies, without at the same time subverting the representation of man-made artifacts.

  18. Francis Bacon: teory, method and contributions to the education

    Directory of Open Access Journals (Sweden)

    Roberto Carlos Simões Galvão

    2007-04-01

    Full Text Available In the present article, we propose a brief analysis of Francis Bacon’s thought (1561-1626 and his contributions to the Education. With Bacon, the old religious or metaphysical character of knowledge was substituted by the objectivity of the experimental science, something unknown until then. The science started to represent a means in search of an end, i.e., man’s control over nature. The desire of Bacon to promote a reorganization of the power of the human knowledge, not based on the old scholastic knowledge, but in the new scientific knowledge, was shared by educators, philosophers and statesmen of his time. The role of the school would be to assure the dissemination of this new knowledge which, properly unified, would be within reach of all the children

  19. Experimental vibration level analysis of a Francis turbine

    International Nuclear Information System (INIS)

    Bucur, D M; Dunca, G; Calinoiu, C

    2012-01-01

    In this study the vibration level of a Francis turbine is investigated by experimental work in site. Measurements are carried out for different power output values, in order to highlight the influence of the operation regimes on the turbine behavior. The study focuses on the turbine shaft to identify the mechanical vibration sources and on the draft tube in order to identify the hydraulic vibration sources. Analyzing the vibration results, recommendations regarding the operation of the turbine, at partial load close to minimum values, in the middle of the operating domain or close to maximum values of electric power, can be made in order to keep relatively low levels of vibration. Finally, conclusions are drawn in order to present the real sources of the vibrations.

  20. Simulations of Steady Cavitating Flow in a Small Francis Turbine

    Directory of Open Access Journals (Sweden)

    Ahmed Laouari

    2016-01-01

    Full Text Available The turbulent flow through a small horizontal Francis turbine is solved by means of Ansys-CFX at different operating points, with the determination of the hydrodynamic performance and the best efficiency point. The flow structures at different regimes reveal a large flow eddy in the runner and a swirl in the draft tube. The use of the mixture model for the cavity/liquid two-phase flow allowed studying the influence of cavitation on the hydrodynamic performance and revealed cavitation pockets near the trailing edge of the runner and a cavitation vortex rope in the draft tube. By maintaining a constant dimensionless head and a distributor vane opening while gradually increasing the cavitation number, the output power and efficiency reached a critical point and then had begun to stabilize. The cavitation number corresponding to the safety margin of cavitation is also predicted for this hydraulic turbine.

  1. Prediction of dynamic blade loading of the Francis-99 turbine

    International Nuclear Information System (INIS)

    Nicolle, J; Cupillard, S

    2015-01-01

    CFD simulations focusing on capturing dynamic fluctuations of the flow for three operating points were performed for a scale model of a high head Francis turbine. A mesh sensitivity study showed an influence of the near wall resolution, consequently a low Reynolds mesh with a SST turbulence model was used. Rotor/stator fluctuations are well reproduced with the full turbine simulation at all operating points. Velocity contours and average velocity profiles from LDV measurements in the draft tube confirm that the flow physics is generally well reproduced. Simplified approaches such as profile transform and Fourier transform underestimated the measured fluctuations. As full turbine simulations were time-consuming, a simulation with only the draft tube was performed at part load to predict the fluctuations in the draft tube cone. The SAS-SST turbulence model was able to capture the vortex rope behavior

  3. Graphical Editor of the DDS Topology Configuration

    CERN Document Server

    Rusinov, Aleksandar

    2015-01-01

    An editor for the DDS topology configuration is created to allow the viewing of an existing topology, the editing of a topology, the creation of a new topology and the saving of a topology as a topology language XML file to be run directly on DDS or to be reloaded again for further editing. The development of the editor was started at GSI Darmstadt at the end of last year. The editor is designed as a web application that works on the client side. Recent and powerful JavaScript libraries were used – ReactJS and JointJS. It has two menus for editing – one for the declarative part and another for the executable part. A graph visualisation of the topology has also been developed and implemented fully to the editor. The output files have been tested and fully verified on the DDS. Future work will involve representation of the pipeline process and investigation on behavior when larger and more sophisticated topologies are used.

    This document describes an X-window based Schema Editor for the Object-Protocol Model (OPM). OPM is a data model that supports the specification of complex object and protocol classes. objects and protocols are qualified in OPM by attributes that are defined over (associated with) value classes. Connections of object and protocol classes are expressed in OPM via attributes. OPM supports the specification (expansion) of protocols in terms of alternative and sequences of component (sub) protocols. The OPM Schema Editor allows specifying, displaying, modifying, and browsing through OPM schemas. The OPM Schema Editor generates an output file that can be used as input to an OPM schema translation tool that maps OPM schemas into definitions for relational database management systems. The OPM Schema Editor was implemented using C++ and the X11 based Motif toolkit, on Sun SPARCstation under Sun Unix OS 4.1. This document consists of the following parts: (1) A tutorial consisting of seven introductory lessons for the OPM Schema Editor. (2) A reference manual describing all the windows and functions of the OPM Schema Editor. (3) An appendix with an overview of OPM.

  18. Workbench surface editor of brain cortical surface

    Dow, Douglas E.; Nowinski, Wieslaw L.; Serra, Luis

    1996-04-01

    We have developed a 3D reach-in tool to manually reconstruct 3D cortical surface patches from 2D brain atlas images. The first application of our cortex editor is building 3D functional maps, specifically Brodmann's areas. This tool may also be useful in clinical practice to adjust incorrectly mapped atlas regions due to the deforming effect of lesions. The cortex editor allows a domain expert to control the correlation of control points across slices. Correct correlation has been difficult for 3D reconstruction algorithms because the atlas slices are far apart and because of the complex topology of the cortex which differs so much from slice to slice. Also, higher precision of the resulting surfaces is demanded since these define 3D brain atlas features upon which future stereotactic surgery may be based. The cortex editor described in this paper provides a tool suitable for a domain expert to use in defining the 3D surface of a Brodmann's area.

  20. The Visual Shock of Francis Bacon: An essay in neuroesthetics

    Directory of Open Access Journals (Sweden)

    Semir eZeki

    2013-12-01

    Full Text Available In this paper we discuss the work of Francis Bacon in the context of his declared aim of giving a visual shock. We explore what this means in terms of brain activity and what insights into the brain’s visual perceptive system his work gives. We do so especially with reference to the representation of faces and bodies in the human visual brain. We discuss the evidence that shows that both these categories of stimuli have a very privileged status in visual perception, compared to the perception of other stimuli, including man-made artifacts such as houses, chairs and cars. We show that viewing face and house stimuli that depart significantly from a normal representation of faces and bodies entails a significant difference in the pattern of brain activation. We argue that Bacon succeeded in delivering his visual shock because he subverted the normal neural representation of faces and bodies, without at the same time subverting the representation of man-made artifacts.

  1. Civil history and poetry, certainty and truth in Francis Bacon

    Directory of Open Access Journals (Sweden)

    Silvia Manzo

    2015-02-01

    Full Text Available This article aims at studying key components of Francis Bacon’s theory of history and of his work as practitioner of civil history, particularly in regard to truth and certainty in historical narratives. It compares Bacon’s theories of history and poetry, and the way in which he conceives their relation to certainty, truth and fiction. It analyzes mainly two sorts of writings. On the one hand, it investigates the programmatic texts where Bacon’s views of history and poetry are developed. On the other hand, it examines the finished and unfinished civil histories written by Bacon as historian. In addition, the article evaluates Bacon’s stances against the background of Renaissance and early modern English historiography. It concludes that although history and poetry constitute separate branches in Bacon’s classification of learning, they share important elements, in keeping with the view of poetry maintained by his contemporary Philip Sidney. Thus, Bacon included fictional patterns in his historical narrative and distinguished certainties from conjectures in a particular way. This attitude towards civil history shows a strong contrast to Bacon’s methodology for natural histories, which, in order to reach certainty, staunchly recommends to exclude any fictional narrative in reporting the facts of nature.

  2. The medical philosophy of Francis Bacon (1561-1626).

    Science.gov (United States)

    Boss, J

    1978-01-01

    Francis Bacon's view of man is dualistic but, although he takes note of mental faculties, he makes the relation between mind and body, rather than the substance of mind, the basis for enquiry into mental processes and, more particularly, for the medically relevant study of mind. (He uses "mind" and "soul" as equivalent terms.) The healing of the body requires study of the body, and the ineffectiveness of physicians is due to their failure in this respect rather than to the body's complexity. To learn about the body requires clinical observation and recording, together with the comparison of bodies, experiments on living animals and attention to pathological changes. The aims of medicine should include not only the restoration of health but also the relief of suffering and they are not to be limited by putting aside a disease as incurable. To learn from treatment it must be fixed in its ordering with controlled and limited variation. Bacon has no separation of medicine from natural science; his philosophy of medicine is his general philosophy of the advancement of knowledge, but limited to a particular field of application. If medicine is separated from natural philosophy it is changed wholly or greatly into empiricism.

  3. Computation of Cavitating Flow in a Francis Hydroturbine

    Science.gov (United States)

    Leonard, Daniel; Lindau, Jay

    2013-11-01

    In an effort to improve cavitation characteristics at off-design conditions, a steady, periodic, multiphase, RANS CFD study of an actual Francis hydroturbine was conducted and compared to experimental results. It is well-known that operating hydroturbines at off-design conditions usually results in the formation of large-scale vaporous cavities. These cavities, and their subsequent collapse, reduce efficiency and cause damage and wear to surfaces. The conventional hydro community has expressed interest in increasing their turbine's operating ranges, improving their efficiencies, and reducing damage and wear to critical turbine components. In this work, mixing planes were used to couple rotating and stationary stages of the turbine which have non-multiple periodicity, and provide a coupled solution for the stay vanes, wicket gates, runner blades, and draft tube. The mixture approach is used to simulate the multiphase flow dynamics, and cavitation models were employed to govern the mass transfer between liquid and gas phases. The solution is compared with experimental results across a range of cavitation numbers which display all the major cavitation features in the machine. Unsteady computations are necessary to capture inherently unsteady cavitation phenomena, such as the precessing vortex rope, and the shedding of bubbles from the wicket gates and their subsequent impingement upon the leading edge of the runner blades. To display these features, preliminary unsteady simulations of the full machine are also presented.

    The applications of Computational Fluid Dynamics, CFD, to hydraulic machines life require the ability to handle turbulent flows and to take into account the effects of turbulence on the mean flow. Nowadays, Direct Numerical Simulation, DNS, is still not a good candidate for hydraulic machines simulations due to an expensive computational time consuming. Large Eddy Simulation, LES, even, is of the same category of DNS, could be an alternative whereby only the small scale turbulent fluctuations are modeled and the larger scale fluctuations are computed directly. Nevertheless, the Reynolds-Averaged Navier-Stokes, RANS, model have become the widespread standard base for numerous hydraulic machine design procedures. However, for many applications involving wall-bounded flows and attached boundary layers, various hybrid combinations of LES and RANS are being considered, such as Detached Eddy Simulation, DES, whereby the RANS approximation is kept in the regions where the boundary layers are attached to the solid walls. Furthermore, the accuracy of CFD simulations is highly dependent on the grid quality, in terms of grid uniformity in complex configurations. Moreover any successful structured and unstructured CFD codes have to offer a wide range to the variety of classic RANS model to hybrid complex model. The aim of this study is to compare the behavior of turbulent simulations for both structured and unstructured grids topology with two different CFD codes which used the same Francis turbine. Hence, the study is intended to outline the encountered discrepancy for predicting the wake of turbine blades by using either the standard k-ε model, or the standard k-ε model or the SST shear stress model in a steady CFD simulation. Finally, comparisons are made with experimental data from the EPFL Laboratory for Hydraulic Machines reduced scale model measurements.

  8. A Virtual Environments Editor for Driving Scenes

    2003-12-01

    Full Text Available The goal of this project was to enable the rapid creation of three-dimensional virtual driving environments. We designed and implemented a high-level scene editor that allows a user to construct a driving environment by pasting icons that represent 1 road segments, 2 road signs, 3 trees and 4 buildings. These icons represent two- and three-dimensional objects that have been predesigned. Icons can be placed in the scene at specific locations (x, y, and z coordinates. The editor includes the capability of a user to "drive" a vehicle using a computer mouse for steering, accelerating and braking. At any time during the process of building a virtual environment, a user may switch to "Run Mode" and inspect the three-dimensional scene by "driving" through it using the mouse. Adjustments and additions can be made to the virtual environment by going back to "Build Mode". Once a user is satisfied with the threedimensional virtual environment, it can be saved in a file. The file can used with Java3D software that enables the traversing of three-dimensional environments. The process of building virtual environments from predesigned icons can be applied to many other application areas. It will enable novice computer users to rapidly construct and use three-dimensional virtual environments.

    When Professor Anders Bárány took over as the Executive Editor of Physica Scripta, in 1986, he talked of his trepidation at having to 'dress himself' in his predecessor's 'editorial coveralls'. At that time, they had been worn by Professor Nils Robert Nilsson, a major figure in the physics community, for almost 20 years. Just one year prior to this, Professor Roger Wäppling had been recruited to the position of Subeditor in conjunction with a decision to expand the number of contributions in the field of condensed matter physics, to turn it into one of the dominant subjects in the broad-based journal. Physica Scripta had already gained a reputation for being a high quality journal with wide coverage of both experimental and theoretical physics. Interestingly, in the mid 1980s, the number of papers submitted had been growing and an impressive 250 submissions per year had been attained, with all of the manuscripts being handled in-house. Not many miles away in the town of Uppsala, a group of English students was stepping off a train on a magnificent snowy day in January to embark on their final year projects. A couple of us enjoyed ourselves so much that we stayed on afterwards as PhD students, thereby encountering the mixed pleasure of studying physics in a second language for the first time. I used to copy the notes down meticulously in Swedish, then try to work backwards with a textbook to improve my language skills. One day, returning from a particularly incomprehensible lecture on solid state physics, I showed my roommates my notes and asked if they could please explain what the lecture had been about: 'I don't know', they replied, 'but this bit is about sheep!' Meanwhile, back at Physica Scripta, the journal continued to flourish: 400 submissions were received in 1996, and the march of progress was well underway. Manuscripts could now be sent in on disks and Physica Scripta was available on the World Wide Web. Roger was appointed to manage the journal and

Concerning that motor vehicles contribute about 14% of the global CO2 emission, it is understandable that many research efforts are devoted to processes in internal combustion engines and use of biofuels. The number of submitted papers dealing with processes in internal combustion engines is growing from months to months, so in the journal Thermal Science also will published in 2011 one issue devoted to the same topics. Papers submitted are already in the reviewing process. Professor Dragoslava Stojiljkovi} and Professor Stojan Petrovi} as Guest editors, had again a difficult task to make appropriate choice of the papers, covering wide range of topics. I am very grateful to Guest editors for their extremely competent choice of the topics and papers. Reviewers of the papers made, also, tremendous contributions to the quality of the papers published. This time, also, as in No. 3, 2009, we asked experts in traffic engineering to give their contribution. They pointed out importance of the internal combustion engine energy efficiency, vehicle fleet operation management and logistic efficiency, and painted large scale picture of the environmental problems caused by large density traffic. We hope that this point of view will make new impulse for many new joint projects with the aim to investigate impact of the processes in internal combustion engines and logistic of motor fleet management, and organization of traffic flows, especially in large towns, on environment. Papers devoted to the thermal processes in internal combustion engines are grouped in Part one of this issue. Due to large number of papers accepted for publication, we have been forced to introduce Part two, in which are grouped selected

    A molecule editor, i.e. a program facilitating graphical input and interactive editing of molecules, is an indispensable part of every cheminformatics or molecular processing system. Today, when a web browser has become the universal scientific user interface, a tool to edit molecules directly within the web browser is essential. One of the most popular tools for molecular structure input on the web is the JME applet. Since its release nearly 15 years ago, however the web environment has changed and Java applets are facing increasing implementation hurdles due to their maintenance and support requirements, as well as security issues. This prompted us to update the JME editor and port it to a modern Internet programming language - JavaScript. The actual molecule editing Java code of the JME editor was translated into JavaScript with help of the Google Web Toolkit compiler and a custom library that emulates a subset of the GUI features of the Java runtime environment. In this process, the editor was enhanced by additional functionalities including a substituent menu, copy/paste, drag and drop and undo/redo capabilities and an integrated help. In addition to desktop computers, the editor supports molecule editing on touch devices, including iPhone, iPad and Android phones and tablets. In analogy to JME the new editor is named JSME. This new molecule editor is compact, easy to use and easy to incorporate into web pages. A free molecule editor written in JavaScript was developed and is released under the terms of permissive BSD license. The editor is compatible with JME, has practically the same user interface as well as the web application programming interface. The JSME editor is available for download from the project web page http://peter-ertl.com/jsme/

  4. Martin Stutzmann: Editor, Teacher, Scientist and Friend

    Cardona, Manuel

    2005-03-01

    On 2 January 1995 Martin Stutzmann became Editor-in-Chief of physica status solidi, replacing Professor E. Gutsche, who had led the journal through the stormy period involving the fall of the Iron Curtain, the unification of Germany and the change in its Eastern part, where physica status solidi was based, from socialism as found in the real world (a German concept) to real world capitalism. In 1995 it was thought that the process had been completed (we should have known better!) and after the retirement of Prof. Gutsche the new owners of physica status solidi (Wiley-VCH) decided that a change in scientific management was desirable to adapt to the new socio-political facts and to insure the scientific continuity of the journal.Martin had moved in 1993 from my department at the Max-Planck-Institute to Munich where he soon displayed a tremendous amount of science man- agement ability during the build-up of the Walter Schottky Institute. The search for a successor as Edi- tor-in-Chief was not easy: the job was not very glamorous after the upheavals which had taken place in the editorial world following the political changes. Somebody in the Editorial Boards must have suggested Martin Stutzmann. I am sure that there was opposition: one usually looks for a well-established person ready to leave his direct involvement in science and take up a new endeavor of a more administrative nature. Nevertheless, the powers that be soon realized that Martin was an excellent, if somewhat unconventional candidate who had enough energy to remain a topnotch scientist and to lead the journal in the difficult times ahead: he was offered the job. In the negotiations that followed, he insisted in getting the administrative structures that would allow him to improve the battered quality of the journal and to continue his scientific productivity. Today we are happy to see that he succeeded in both endeavors. The journal has since grown in size and considerably improved its quality

    affiliated at the Faculty of Mechanical Engineering in Kragujevac. Guest editor, Professor Dr. Milun Babić, had an extremely difficult job to make proper selection of papers, representing research results of his Department and Faculty of Mechanical Engineering, not only in fundamental and applied research, but also in practical applications. I am greatly thankful to him since he presented not only most interesting scientific results, but also cases of best practise realized on the basis of the research results. At the same time, in his introductory review paper he explain research policy in the field of thermal sciences, energy efficiency and use of renewable energy sources having the main aim to solve more important energy and environmental problems of the local community, as well as to introduce energy management, environmental management, and sustainable development. This is one of the main characteristics of the set of papers selected by Guest editor for this Supplement issue. Realization of the full chain – fundamental research, applied research development and demonstration (R&D&D is not too often, especially in developing countries. I hope, that paper selection that made for this issue by Guest editor Professor Dr. Milun Babić, in many cases evidently presents that it is possible, even with small funds available in Serbia.

  11. Power Swing Generated in Francis Turbines by Part Load and Overload Instabilities

    Directory of Open Access Journals (Sweden)

    2017-12-01

    Full Text Available Hydropower plays a key role in the actual energy market due to its fast response and regulation capacity. In that way, hydraulic turbines are increasingly demanded to work at off-design conditions, where complex flow patterns and cavitation appear, especially in Francis turbines. The draft tube cavitation surge is a hydraulic phenomenon that appears in Francis turbines below and above its Best Efficiency Point (BEP. It is a low frequency phenomenon consisting of a vortex rope in the runner outlet and draft tube, which can become unstable when its frequency coincides with a natural frequency of the hydraulic circuit. At this situation, the output power can significantly swing, endangering the electrical grid stability. This study is focused on the detection of these instabilities in Francis turbines and their relationship with the output power swings. To do so, extensive experimental tests for different operating conditions have been carried out in a large prototype Francis turbine (444 MW of rated power within the frame of the European Project Hyperbole (FP7-ENERGY-2013-1. Several sensors have been installed in the hydraulic circuit (pressure sensors in the draft tube, spiral casing, and penstock, in the rotating and static structures (vibration sensors, proximity probes, and strain gauges in the runner and in the shaft, as well as in the electrical side (output power, intensity, and voltage. Moreover, a numerical Finite Element Method (FEM has been also used to relate the hydraulic excitation with the output power swing.

    Full Text Available Style and format are important criteria for evaluating a journal and indexing it in major databases. In Korean science, technology, and medical journals, interest in manuscript editing has increased over the past seven to eight years, and the responsibilities of manuscript editors have expanded as well. However, since no clear standards for the roles and qualifications for manuscript editors are yet available, a formal certification system is needed to establish appropriate standards and to provide professional training. To identify ways of developing a manuscript editor certification program in Korea, this study investigated similar certification programs in and outside the country and surveyed 195 Korean editors, manuscript editors, publishers, and medical librarians. The survey revealed that manuscript editors were necessary (mean score of 4.38 on a five-point Likert scale, with a score of 5 indicating strong agreement, and that their main contributions were efficiently managing the editorial board, improving the accuracy of references, and accelerating the editing process. The respondents were also positive about the possibility of implementing a manuscript editor certification; 45.1% showed interest in becoming certified, and 47.1% reported interest in hiring a certified manuscript editor. Regarding the system for issuing certification, respondents favored a professional training course (53.1%, validation of work experience (27.1%, or an examination (16.8%. This study concludes that it is essential to establish a formal certification program to train manuscript editors properly, and an examination system is the most efficient and suitable method for managing the certification process.

  2. EDITORIAL: Incoming Editor-in-Chief

    Science.gov (United States)

    Webb, Steve

    2006-01-01

    Physics in Medicine and Biology (PMB) is a journal that originated in the UK but is now rightly regarded as one of the pre-eminent international journals for the publication of material coming within its remit. It is 50 years old and its maturity is an outcome of the consistent support of high performing authors, a supportive and professional publishing house, dedicated referees, many vigorous and conscientious editorial boards and the collective input of the 10 previous Editors as listed in his incoming editorial (January 2000 issue) by the retiring Editor, Professor Alun Beddoe. The scientific climate and it associated publication modus operandi in the 1950s was very different from that at the current time and the journal has evolved to reflect this. Hence today the scope of content is somewhat broader, the size of the journal is vastly greater, the whole publication process is slicker and more efficient and a paper in PMB is highly prized by its authors and those who look to quality factors and impact. The quality of the journal still relies on the voluntary labour and expertise of its busy international referees and Board members. For many years I have tried to place my own research material in PMB and encourage my teams to do likewise, not only acknowledging the prestige of the journal but also because of the extraordinarily fast turnaround time of all the processes without any loss of quality. This serves us very well and the publishing team are to be congratulated. Some things seem to change more slowly or not at all, however. The prediction, when I started my research career, that books and journals would be dinosaurs by now has manifestly not come true and, whilst most of us are addicted (and why not?) to the electronic ways of doing things that can be done by more traditional ways, PMB and a packet of reprints from time to time arriving by post still has a reassuring feel despite the fact that the papers have been `on-line' for a while before.

    Full Text Available Welcome to the first issue of Journal of Medical Physiology! Journal of Medical Physiology is a high-quality, peer reviewed, open access journal which will focus on physiology, biology, and neuroscience and their applications in clinic from the molecular levels to the levels of organs and systems.  In recent years knowledge of physiology has been under a great progress and is being taught as one of the major courses in medicine and allied fields in the universities. Many researchers are doing research in this field and try to find the basic mechanism and appropriate solution for diseases which are difficult to treat. The editorial board wants to create a balanced journal to help the researchers in the field of medicine and physiology to share the results of their research work. Like all good science, medical physiology has no national boundaries. Although we each have found our own niche where we work and feel most comfortable, science language is a common language and by this language scientist can learn from each other. We want Journal of Medical Physiology to be an international forum for sharing the best ideas. It will help researcher in the field of medicine and physiology to keep up with the science. We hope that this journal plays a major role in the development of the physiological sciences and contribute to the diffusion of scientific knowledge and to promote discussion among scientist. The journal will include original researches that are practical applications of known techniques as well as theoretical advances at the physiological sciences and medicine. I consider it a great honor being as Editor-in-Chief of Journal of Medical Physiology and I will do my best to face all challenges that confront the journal and striving to increase the quality and impact of the journal's content. Despite the inevitable push towards publishing in the highest impact factor journals possible, the other side of the coin is ensuring that your work is

  7. Designing Epigenome Editors: Considerations of Biochemical and Locus Specificities.

    Science.gov (United States)

    Sen, Dilara; Keung, Albert J

    2018-01-01

    The advent of locus-specific protein recruitment technologies has enabled a new class of studies in chromatin biology. Epigenome editors enable biochemical modifications of chromatin at almost any specific endogenous locus. Their locus specificity unlocks unique information including the functional roles of distinct modifications at specific genomic loci. Given the growing interest in using these tools for biological and translational studies, there are many specific design considerations depending on the scientific question or clinical need. Here we present and discuss important design considerations and challenges regarding the biochemical and locus specificities of epigenome editors. These include how to account for the complex biochemical diversity of chromatin; control for potential interdependency of epigenome editors and their resultant modifications; avoid sequestration effects; quantify the locus specificity of epigenome editors; and improve locus specificity by considering concentration, affinity, avidity, and sequestration effects.

    2001-01-01

    The Monte Carlo N-Particle (MCNP) visual editor1,2,3 is used throughout the world for displaying and creating complex MCNP geometries. The visual editor combines the Los Alamos MCNP Fortran code with a C front end to provide a visual interface. A big advantage of this approach is that the particle transport routines for MCNP are available to the visual front end. The latest release of the visual editor by Pacific Northwest National Laboratory enables the user to plot transport data points on top of a two-dimensional geometry plot. The user can plot source points, collisions points, surface crossings, and tally contributions. This capability can be used to show where particle collisions are occurring, verify the effectiveness of the particle biasing, or show which collisions contribute to a tally. For a KCODE (criticality source) calculation, the visual editor can be used to plot the source points for specific cycles

    2009-04-01

    The short form of the Francis Scale of Attitude Toward Christianity (L. J. Francis, 1992) is a 7-item Likert-type scale that shows high homogeneity among adolescents. The psychometric performance of a shorter version of this scale has not been explored. The authors aimed to determine the internal consistency of a 5-item form of the Francis Scale of Attitude Toward Christianity among 405 students from a school in Cartagena, Colombia. The authors computed the Cronbach's alpha coefficient for the 5 items with a greater corrected item-total punctuation correlation. The version without Items 2 and 7 showed internal consistency of .87. The 5-item version of the Francis Scale of Attitude Toward Christianity exhibited higher internal consistency than did the 7-item version. Future researchers should corroborate this finding.

  12. Effects of draft tube on the hydraulic performance of a Francis turbine

    2013-01-01

    The draft tube is an important component of a Francis turbine which influences the hydraulic performance. It is located just under the runner and allowed to decelerate the flow velocity exiting the runner, thereby converting the excess of kinetic energy into static pressure. In this study, we have numerically investigated the hydraulic performance of a Francis turbine on the 15MW hydropower generation with various design parameters (three types of draft tube, thickness of guide vane) through a three-dimensional numerical method with the SST turbulent model. The vortex rope characteristics of the draft tube were confirmed. The results of the vortex flow fields and flow characteristics were graphically depicted with different design parameters and operating conditions

  13. Robust Finite-Time Terminal Sliding Mode Control for a Francis Hydroturbine Governing System

    Directory of Open Access Journals (Sweden)

    Fengjiao Wu

    2016-01-01

    Full Text Available The robust finite-time control for a Francis hydroturbine governing system is investigated in this paper. Firstly, the mathematical model of a Francis hydroturbine governing system is presented and the nonlinear vibration characteristics are analyzed. Then, on the basis of finite-time control theory and terminal sliding mode scheme, a new robust finite-time terminal sliding mode control method is proposed for nonlinear vibration control of the hydroturbine governing system. Furthermore, the designed controller has good robustness which could resist external random disturbances. Numerical simulations are employed to verify the effectiveness and superiority of the designed finite-time sliding mode control scheme. The approach proposed in this paper is simple and also provides a reference for relevant hydropower systems.

    2010-01-01

    Operating Francis turbines at partial discharge is often hindered by the development of the helical vortex (so-called vortex rope) downstream the runner, in the draft tube cone. The unsteady pressure field induced by precessing vortex rope leads to pressure fluctuations. The paper presents the experimental investigations of the unsteady pressure field generated by precessing vortex rope and its associated pressure fluctuations into a draft tube of the Francis turbine operating at partial discharge. In situ measurements are performed in order to evaluate the pressure fluctuations and vortex rope frequency at partial load operation. Three pressure taps are installed on the cone wall of the draft tube in order to record the unsteady pressure. As a result, the Fourier spectra are obtained in order to evaluate the amplitude of pressure fluctuations and vortex rope frequency. Moreover, the wall pressure recovery along to the draft tube cone is acquired. Finally, conclusions are drawn in order to present the vortex rope effects.

In 1953, in a collaborative study, Francis Crick and James Watson discovered the DNA double helix, and in 1962 they and Maurice Wilkins were awarded the Noble Prize in Physiology or Medicine. Crick subsequently became very interested in neuroscience, particularly consciousness and its relationship to the claustrum, a small gray matter structure between the insula and putamen.

    Drawing on the classic model of balanced affect, the Francis Burnout Inventory (FBI) conceptualised good work-related psychological health among clergy in terms of negative affect being balanced by positive affect. In the FBI negative affect is assessed by the Scale of Emotional Exhaustion in Ministry (SEEM) and positive affect is assessed by the Satisfaction in Ministry Scale (SIMS). In support of the idea of balanced affect, previous work had shown a significant interaction between the effe...

    It is a pleasure and an honour for me to be taking over as Editor-in-Chief of Measurement Science and Technology. MST is well known across research communities worldwide as a leading journal in which to publish new techniques and instrumentation. It has gained this enviable position largely because of the excellent guidance of its Editorial Board and dedicated staff at Institute of Physics Publishing over many years. I want to highlight in particular the contribution of the outgoing Editor Peter Hauptmann, and other Editors before him, in making the journal truly international. We thank Peter immensely for all his hard work in leading the journal, having exceptionally served two terms, each of five years. I come into the post of Editor at a very interesting and challenging time for research. The global recession is leading to cuts in research funding in many countries, researchers and their outputs are coming under closer scrutiny than ever before, and more is being expected of them. Journals play a critical role in monitoring and maintaining research standards, but we should be careful not to assume that journal Impact Factor is the sole measure of research quality. Although expediency may sometimes demand it, Impact Factor, as practitioners know, is subject dependent. One of the great things about science and technology for me is its level playing field. The key point is still innovation no matter where the work is done or where it is published. MST has a long pedigree of being the natural home of the highest quality papers from leading researchers wishing to report novel instrumentation and techniques. 2013 will mark the 90th anniversary of MST and we look forward to celebrating in style its sustained success. I recall with pride the first paper I published in Journal of Physics E: Scientific Instruments (as MST was previously titled) back in 1977. The paper reported the design and application of an early fluorescence lifetime spectrometer that I had constructed

  1. The calculation of fluid-structure interaction and fatigue analysis for Francis turbine runner

    2012-01-01

    Francis turbine, as a widely used hydro turbine, is especially suited for the hydropower station with high hydraulic head and higher hydraulic head. For such turbine generator units all around the world, the crack streaks usually come out after a long time use and the resulted accidents may cause huge losses. Hence, it is meaningful to refine the design assuring the stability and safety of the Francis turbine. In this paper, the stiffness and strength as well as the fatigue life of the Francis turbine are studied. Concerning on the turbine of one certain hydropower station, the flow field inside the turbine are first simulated and the pressure distribution around the blades are derived. Meanwhile, the stress distributions of the blades are also obtained. Based on these, the fatigue analyses are applied on the turbine. According to the results of fatigue analyses, some optimal designs on the turbine are verified. The results show that with the optimal designs, the hydraulic performances of the turbine do not change too much while the maximum stress on the turbine decrease and the fatigue life increase as well.

  2. Hydroacoustic simulation of rotor-stator interaction in resonance conditions in Francis pump-turbine

    Combined effect of rotating pressure field related to runner blade and wakes of wicket gates leads to rotor stator interactions, RSI, in Francis pump-turbines. These interactions induce pressures waves propagating in the entire hydraulic machine. Superposition of those pressure waves may result in standing wave in the spiral casing and rotating diametrical mode in the guide vanes and can cause strong pressure fluctuations and vibrations. This paper presents the modeling, simulation and analysis of Rotor-Stator Interaction of a scale model of a Francis pump-turbine and related test rig using a one-dimensional approach. The hydroacoustic modeling of the Francis pump-turbine takes into account the spiral casing, the 20 guide vanes, the 9 rotating runner vanes. The connection between stationary and rotating parts is ensured by a valve network driven according to the unsteady flow distribution between guide vanes and runner vanes. Time domain simulations are performed for 2 different runner rotational speeds in turbine mode. The simulation results are analyzed in frequency domain and highlights hydroacoustic resonance between RSI excitations and the spiral case. Rotating diametrical mode in the vaneless gap and standing wave in the spiral case are identified. The influence of the resonance on phase and amplitude of pressure fluctuations obtained for both the spiral case and the vaneless gap is analyzed. The mode shape and frequencies are confirmed using eigenvalues analysis.

    Scientific editors are responsible for deciding which articles to publish in their journals. However, we have not found documentation of their required knowledge, skills, and characteristics, or the existence of any formal core competencies for this role. We describe the development of a minimum set of core competencies for scientific editors of biomedical journals. The 14 key core competencies are divided into three major areas, and each competency has a list of associated elements or descriptions of more specific knowledge, skills, and characteristics that contribute to its fulfillment. We believe that these core competencies are a baseline of the knowledge, skills, and characteristics needed to perform competently the duties of a scientific editor at a biomedical journal.

    The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship - emphasizing the importance of responsibility and accountability -, have been proposed. Last year, a new editorial initiative to foster sharing of clinical trial data was launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and editors belonging to the Editors' Network of the European Society of Cardiology.

  16. A Song in the Dark. Francis of Assisi’s Canticle of Brother Sun

    Directory of Open Access Journals (Sweden)

    Speelman Willem Marie

    2016-10-01

    Full Text Available The Canticle of the Creatures or Canticle of Brother Sun is based on a particular way of perceiving reality. Francis, who had turned away from ‘the world’, discovered a different way of looking at it. This is a divine way of perceiving, in which the senses do not grasp reality, but accept it as it communicates itself. This way of perceiving is only possible if one does not attempt to master the environment, but allows one’s senses to be weak. It is significant, therefore, that this song of praise was born at a moment of the utmost despair and weakness. The song’s content is in line with this weak perception: it is not about Francis who praises God and (or for His creatures, but rather it is a testimony that the creatures-the elements-are already praising God, and a prayer that He should let Himself be praised by the creatures. Also in line with this weak perception is the fact that the creatures are praised just as they communicate themselves to Francis: as bodies. The theology of this song is that the creatures through their bodies resonate (strengthen, and colour the blessings that come from God, thereby making His blessing present here on earth. Francis’ role is to give a voice and a language to the heavenly praises as they resound in his environment. The transformative power of this song is that we, whether consciously or not, do the same thing when we participate in this song.

  18. Kamide reflects on JGR and the role of editor

    Science.gov (United States)

    Woods, Peter

    After serving the space physics community for more than 11 years, Y. Kamide of the Solar-Terrestrial Environment Laboratory at Nagoya University in Toyokawa, Japan, retired as editor of the Journal of Geophysical Research-Space Physics for the Asian/Pacific region. He had been a JGR editor since AGU first opened two editorial offices in Europe and the Asian/Pacific region in 1989. Even as the initial JGR editor in Asia, Kamide was not new to AGU editorial business. Before accepting the JGR position, Kamide served 3 years as the editor in Japan for Geophysical Research Letters.According to Kamide, over the last 5 years, the number of high-quality submissions to JGR in the Asian/Pacific region has increased dramatically, by a factor of 2.5. This increase came mostly from the younger generation of scientists, which bodes well for the future of JGR and space physics in general. Together with the substantial contributions to JGR from the European community, this achievement has been recognized by AGU as proof that JGR is truly an international journal of the highest editorial standards.

However, clinical pedigree datasets can be difficult to manage, as they are time consuming to capture, and can be difficult to build, manipulate and visualize graphically. Several standalone graphical pedigree editors and drawing applications exist but there are no freely available lightweight graphical pedigree editors that can be easily configured and incorporated into web applications. We developed 'pedigreejs', an interactive graphical pedigree editor written in JavaScript, which uses standard pedigree nomenclature. Pedigreejs provides an easily configurable, extensible and lightweight pedigree editor. It makes use of an open-source Javascript library to define a hierarchical layout and to produce images in scalable vector graphics (SVG) format that can be viewed and edited in web browsers. The software is freely available under GPL licence (https://ccge-boadicea.github.io/pedigreejs/). tjc29@cam.ac.uk. Supplementary data are available at Bioinformatics online.

    Serjeantson, Richard

    2017-01-01

    Francis Bacon's earliest surviving natural philosophical treatise (composed circa 1603) bears the title Valerius Terminus of the Interpretation of Nature. This study, resting on fresh attention to the surviving authorial manuscript, has three goals. It begins by identifying a lost precursor work apparently entitled "Of Active Knowledge." It then examines the significance of the pseudonyms Bacon chose to introduce his ideas, considering especially his invocation of Erasmus's emblem, the Roman deity Terminus. Finally, it shows how the Valerius Terminus's global vision of contemporary knowledge ultimately helped shape the iconography of Bacon's published Instauratio magna.

    For many scientific awards, such as Nobels and Laskers, the maximum number of recipients is three. This Rule of Three forces selection committees to make difficult decisions that increase the likelihood of singling out those individuals who open a new field and continue to lead it. The Rule of Three is reminiscent of art's three-panel triptych, a form that the modern master Francis Bacon used to distill complex stories in a bold way. Copyright © 2016 Elsevier Inc.

    The aim of this study was to establish test-retest reliability of a Spanish version of the Francis Scale of Attitude toward Christianity (Campo-Arias, Oviedo, & Cogollo, 2009) among adolescent students in Cartagena, Colombia. A group of ninth grade students from two public schools in Colombia (N = 157) completed the five-item scale. Cronbach's alphas were .74 and .76 in the first and second administrations, respectively. Both Pearson's rho and intra-class correlation coefficient were .69. A Spanish translation of the 5-item scale had consistent stability over four weeks.

  13. Influence of the rotor-stator interaction on the dynamic stresses of Francis runners

    International Nuclear Information System (INIS)

    Guillaume, R; Scolaro, D; Deniau, J L; Colombet, C

    2012-01-01

    Thanks to advances in computing capabilities and Computational Fluid Dynamics (CFD) techniques, it is now possible to calculate realistic unsteady pressure fields in Francis turbines. This paper will explain methods to calculate the structural loads and the dynamic behaviour in order to optimize the turbine design and maximize its reliability and lifetime. Depending on the operating conditions of a Francis turbine, different hydraulic phenomena may impact the mechanical behaviour of the structure. According to their nature, these highly variable phenomena should be treated differently and specifically in order to estimate the potential risks arising on submerged structures, in particular the runner. The operating condition studied thereafter is the point at maximum power with the maximum head. Under this condition, the runner is excited by only one dynamic phenomenon named the Rotor-Stator Interaction (RSI). The origin of the phenomenon is located on the radial gap of the turbine and is the source of pressure fluctuations. A fluid-structure analysis is performed to observe the influence of that dynamic pressure field on the runner behaviour. The first part of the paper deals with the unsteady fluid computation. The RSI phenomenon is totally unsteady so the fluid simulation must take into account the entire machine and its rotation movement, in order to obtain a dynamic pressure field. In the second part of the paper, a method suitable for the RSI study is developed. It is known that the fluctuating pressure in this gap can be described as a sum of spatial components. By evaluating these components in the CFD results and on the scale model, it is possible to assess the relevance of the numerical results on the whole runner. After this step, the numerical pressure field can be used as the dynamic load of the structure. The final part of the paper presentsthe mechanical finite element calculations. A modal analysis of the runner in water and a harmonic analysis of its

    I started in 2002 as Editor-in-Chief of a well established journal—MST (Measurement Science and Technology). It was a time when modern means of communication offered new opportunities for the scientific community—for all scientists and engineers whether at universities, in industry or at other institutions—to access better quality information in a shorter time. This development helped us to be more efficient in our daily scientific work and to anticipate new trends faster than before. A flood of information was created by different search engines. A few online journals or journals published in emerging countries with a similar profile to MST appeared on the market. MST had to provide new answers in response to these developments. In 2002 I postulated two requirements to the journal. Firstly, the publisher has to be up to date. My impression over the years has been that IOPP is excellently organized. That has made it easier for the board members and all our reviewers to concentrate on the scientific aspects of our input to the journal. During all my visits to Bristol or my contacts with the IOPP staff I always met very professional and enthusiastic staff members. They have not only supported and encouraged the ideas and initiatives of the Editorial Board members, but they have also worked hard on establishing one of the most effective journal operations in the field of measurement science and technology. Many authors are well aware of this. Thus I am able to declare that the first requirement for a successful journal has been met. Secondly, the scientific level has to be high and the journal should attract readers from all over the world. This task was the responsibility of the Editorial Board members and of myself. Our strategy was on the one hand to ensure continuity in MST but on the other hand to be open to new trends and developments. Examples of these new aspects of the journal are fields like micro- and nanometrology, measurement techniques for

  16. Francis Bacon's natural history and the Senecan natural histories of early modern Europe.

    Jalobeanu, Dana

    2012-01-01

    At various stages in his career, Francis Bacon claimed to have reformed and changed traditional natural history in such a way that his new "natural and experimental history" was unlike any of its ancient or humanist predecessors. Surprisingly, such claims have gone largely unquestioned in Baconian scholarship. Contextual readings of Bacon's natural history have compared it, so far, only with Plinian or humanist natural history. This paper investigates a different form of natural history, very popular among Bacon's contemporaries, but yet unexplored by contemporary students of Bacon's works. I have provisionally called this form of natural history'Senecan' natural history, partly because it took shape in the Neo-Stoic revival of the sixteenth-century, partly because it originates in a particular cosmographical reading of Seneca's Naturales quaestiones. I discuss in this paper two examples of Senecan natural history: the encyclopedic and cosmographical projects of Pierre de la Primaudaye (1546-1619) and Samuel Purchas (1577-1626). I highlight a number of similarities between these two projects and Francis Bacon's natural history, and argue that Senecan natural history forms an important aspect in the historical and philosophical background that needs to be taken into consideration if we want to understand the extent to which Bacon's project to reform natural history can be said to be new.

    The prediction of pressure and output power fluctuations amplitudes on Francis turbine prototype is a challenge for hydro-equipment industry since it is subjected to guarantees to ensure smooth and reliable operation of the hydro units. The European FP7 research project Hyperbole aims to setup a methodology to transpose the pressure fluctuations induced by the cavitation vortex rope from the reduced scale model to the prototype generating units. A Francis turbine unit of 444MW with a specific speed value of ν = 0.29, is considered as case study. A SIMSEN model of the power station including electrical system, controllers, rotating train and hydraulic system with transposed draft tube excitation sources is setup. Based on this model, a frequency analysis of the hydroelectric system is performed for all technologies to analyse potential interactions between hydraulic excitation sources and electrical components. Three technologies have been compared: the classical fixed speed configuration with Synchronous Machine (SM) and the two variable speed technologies which are Doubly Fed Induction Machine (DFIM) and Full Size Frequency Converter (FSFC).

  18. Prediction Method for the Complete Characteristic Curves of a Francis Pump-Turbine

    2018-02-01

    Full Text Available Complete characteristic curves of a pump-turbine are essential for simulating the hydraulic transients and designing pumped storage power plants but are often unavailable in the preliminary design stage. To solve this issue, a prediction method for the complete characteristics of a Francis pump-turbine was proposed. First, based on Euler equations and the velocity triangles at the runners, a mathematical model describing the complete characteristics of a Francis pump-turbine was derived. According to multiple sets of measured complete characteristic curves, explicit expressions for the characteristic parameters of characteristic operating point sets (COPs, as functions of a specific speed and guide vane opening, were then developed to determine the undetermined coefficients in the mathematical model. Ultimately, by combining the mathematical model with the regression analysis of COPs, the complete characteristic curves for an arbitrary specific speed were predicted. Moreover, a case study shows that the predicted characteristic curves are in good agreement with the measured data. The results obtained by 1D numerical simulation of the hydraulic transient process using the predicted characteristics deviate little from the measured characteristics. This method is effective and sufficient for a priori simulations before obtaining the measured characteristics and provides important support for the preliminary design of pumped storage power plants.

  19. Dynamic stresses in a Francis model turbine at deep part load

    2017-04-01

    A comparison between numerically obtained dynamic stresses in a Francis model turbine at deep part load with experimental ones is presented. Due to the change in the electrical power mix to more content of new renewable energy sources, Francis turbines are forced to operate at deep part load in order to compensate stochastic nature of wind and solar power and to ensure grid stability. For the extension of the operating range towards deep part load improved understanding of the harsh flow conditions and their impact on material fatigue of hydraulic components is required in order to ensure long life time of the power unit. In this paper pressure loads on a model turbine runner from unsteady two-phase computational fluid dynamics simulation at deep part load are used for calculation of mechanical stresses by finite element analysis. Therewith, stress distribution over time is determined. Since only few runner rotations are simulated due to enormous numerical cost, more effort has to be spent to evaluation procedure in order to obtain objective results. By comparing the numerical results with measured strains accuracy of the whole simulation procedure is verified.

  20. A highly efficient Francis turbine designed for energy recovery in cooling towers

    2015-03-01

    Full Text Available In China, cooling water entering cooling towers still retains surplus pressure between 39,240 and 147,150 Pa. In order to utilize this wasted energy, it is suggested that the surplus water energy can be harnessed to drive a type of hydroturbine installed in the inner platform of cooling tower and make the fan rotate via its coupled shafts. However, conventional hydroturbines are not suited for this job because of their low efficiency or unmatched rotating speed with that of the fan under the operating conditions of cooling towers. In this article, according to the requirements of turbine work environment in cooling towers, a new type of hydroturbine, Francis turbine with ultra-low specific speed (ns  = 50 m.kW, was designed to replace the fan motor in a cooling tower. Primarily, the shape, position, and number of runner blades were designed and optimized through theoretical analyses and computational fluid dynamics simulations. Additionally, metal elliptical volute and single-row ring guide vanes were applied to scale down the structural dimensions. Finally, the optimal scheme of the new Francis turbine was proven to have a high efficiency of 88% and good operation stability through testing of a physical model and can achieve the goal of harvesting renewable energy in the cooling tower.

  1. Research on Francis Turbine Modeling for Large Disturbance Hydropower Station Transient Process Simulation

    Directory of Open Access Journals (Sweden)

    2015-01-01

    Full Text Available In the field of hydropower station transient process simulation (HSTPS, characteristic graph-based iterative hydroturbine model (CGIHM has been widely used when large disturbance hydroturbine modeling is involved. However, by this model, iteration should be used to calculate speed and pressure, and slow convergence or no convergence problems may be encountered for some reasons like special characteristic graph profile, inappropriate iterative algorithm, or inappropriate interpolation algorithm, and so forth. Also, other conventional large disturbance hydroturbine models are of some disadvantages and difficult to be used widely in HSTPS. Therefore, to obtain an accurate simulation result, a simple method for hydroturbine modeling is proposed. By this method, both the initial operating point and the transfer coefficients of linear hydroturbine model keep changing during simulation. Hence, it can reflect the nonlinearity of the hydroturbine and be used for Francis turbine simulation under large disturbance condition. To validate the proposed method, both large disturbance and small disturbance simulations of a single hydrounit supplying a resistive, isolated load were conducted. It was shown that the simulation result is consistent with that of field test. Consequently, the proposed method is an attractive option for HSTPS involving Francis turbine modeling under large disturbance condition.

  2. Velocity and pressure measurements in guide vane clearance gap of a low specific speed Francis turbine

    In Francis turbine, a small clearance gap between the guide vanes and the cover plates is usually required to pivot guide vanes as a part of governing system. Deflection of cover plates and erosion of mating surfaces causes this gap to increase from its design value. The clearance gap induces the secondary flow in the distributor system. This effects the main flow at the runner inlet, which causes losses in efficiency and instability. A guide vane cascade of a low specific speed Francis turbine has been developed for experimental investigations. The test setup is able to produce similar velocity distributions at the runner inlet as that of a reference prototype turbine. The setup is designed for particle image velocimetry (PIV) measurements from the position of stay vane outlet to the position of runner inlet. In this study, velocity and pressure measurements are conducted with 2 mm clearance gap on one side of guide vane. Leakage flow is observed and measured together with pressure measurements. It is concluded that the leakage flow behaves as a jet and mixes with the main flow in cross-wise direction and forms a vortex filament. This causes non-uniform inlet flow conditions at runner blades.

    In the present paper, fully 360 degrees transient and steady-state simulations of a Francis turbine were performed at three operating conditions, namely at part load (PL), best efficiency point (BEP), and high load (HL), using different numerical approaches for the pressure-velocity coupling. The simulation domain includes the spiral casing with stay and guide vanes, the runner and the draft tube. The main target of the investigations is the numerical prediction of the overall performance of the high head Francis turbine model as well as local and integral quantities of the complete machine in different operating conditions. All results were compared with experimental data published by the workshop organization. All CFD simulations were performed at model scale with a new in-house, 3D, unstructured, object-oriented finite volume code within the framework of the open source OpenFOAM library. The novel fully coupled pressure-based solver is designed to solve the incompressible RANS- Equations and is capable of handling multiple references of frame (MRF). The obtained results show that the overall performance is well captured by the simulations. Regarding the local flow distributions within the inlet section of the draft-tube, the axial velocity is better estimated than the circumferential component

    In recent years, cracking phenomenon occurs in many large-sized turbines both nationally and internationally, which has threatened the stable operation of hydraulic turbines. Consequently, Stress characteristics calculation and analysis of a Francis hydraulic turbine runner by application of fluid-structure interaction (FSI) technology become significantly important. In order to introduce two-way coupling technology to hydraulic machinery, two-way FSI technology is applied in this article to calculate and analyze stress characteristics. Through coordinate system transformation, the continuity equations and Navier-Stokes equations in the Cartesian coordinates system are firstly transformed to ALE coordinates system. The fluid field control equations are then constructed and discrete equations can be obtained by using flow-condition-based interpolation (FBIC-C). The structure static mechanics equations used are established in rotation coordinate system, and modeled with the finite method. Two-way coupling is computed by using iteration method. The fluid equations and structure equations are iterated until coupling coefficients converge. According to structure result, the maximum stress, displacement as well as its location can be found. As a result, the most easily wear position can be discovered which provides valuable basis for optimized design and stable operation of Francis hydraulic turbines. After comparing the results with that of one-way coupling, it is discovered that displacements is the key factors which affects the results of one-way and two-way coupling.

We thank both the authors and the referees for working with us on the rather tight schedule necessary to release the issue within one year of the date of the conference. We also thank the invited speakers, B Eckhardt, L Tuckerman, and J M Vega, for contributing keynote papers to this special issue. The series of BIFD symposia started as a small workshop in Madeira, Portugal, in 2004 with no more than 20 participants. This number increased rapidly during the second and third symposia held in 2006 (Denmark) and 2009 (United Kingdom), with 40 and 110 participants, respectively. The 4th BIFD symposium has consolidated this event as one of the leading conferences in hydrodynamic stability, with nearly 200 participants from around the world. The main goal of this conference is to bring together scientists and engineers from different disciplines directly or indirectly related to fluid dynamics, bifurcation theory and hydrodynamic stability theory. The conference covered many research areas within the aforementioned fields, ranging from thermal, shear and centrifugal flows to biofluids, films, drops, viscoelastic flows and magnetohydrodynamics. The structure of the conference, with invited plenary talks and focused sessions, helped the participants find their home in the conference and share state-of-the-art knowledge within the field of hydrodynamic instabilities. The financial support from MICINN (Spanish Ministry of Science and Innovation, Grant no FIS2009-08065-E) and UPC (Universitat Politècnica de Catalunya) is greatly appreciated.

  13. Statement on Publication Ethics for Editors and Publishers

    Science.gov (United States)

    2016-01-01

    The digitization and related developments in journal editing and publishing necessitate increasing the awareness of all stakeholders of science communication in the emerging global problems and possible solutions. Journal editors and publishers are frequently encountered with the fast-growing problems of authorship, conflicts of interest, peer review, research misconduct, unethical citations, and inappropriate journal impact metrics. While the number of erroneous and unethical research papers and wasteful, or 'predatory', journals is increasing exponentially, responsible editors are urged to 'clean' the literature by correcting or retracting related articles. Indexers are advised to implement measures for accepting truly influential and ethical journals and delisting sources with predatory publishing practices. Updating knowledge and skills of authors, editors and publishers, developing and endorsing recommendations of global editorial associations, and (re)drafting journal instructions can be viewed as potential tools for improving ethics of academic journals. The aim of this Statement is to increase awareness of all stakeholders of science communication of the emerging ethical issues in journal editing and publishing and initiate a campaign of upgrading and enforcing related journal instructions.

However, there is now some awareness that re-use of words in research articles to improve the writing or “the English” (which has become a common practice) should be distinguished from intentional deceit for the purpose of stealing other authors’ ideas (which appears to remain a very rare practice). Although it has become almost as easy for editors to detect duplicate text as it is for authors to re-use text from other sources, editors often fail to consider the reasons why researchers resort to this strategy, and tend to consider any text duplication as a symptom of serious misconduct. As a result, some authors may be stigmatized unfairly by being labeled as plagiarists. The article concludes with practical advice for researchers on how to improve their writing and citing skills and thus avoid accusations of plagiarism. PMID:21957412

  17. CMS Configuration Editor: GUI based application for user analysis job

    We present the user interface and the software architecture of the Configuration Editor for the CMS experiment. The analysis workflow is organized in a modular way integrated within the CMS framework that organizes in a flexible way user analysis code. The Python scripting language is adopted to define the job configuration that drives the analysis workflow. It could be a challenging task for users, especially for newcomers, to develop analysis jobs managing the configuration of many required modules. For this reason a graphical tool has been conceived in order to edit and inspect configuration files. A set of common analysis tools defined in the CMS Physics Analysis Toolkit (PAT) can be steered and configured using the Config Editor. A user-defined analysis workflow can be produced starting from a standard configuration file, applying and configuring PAT tools according to the specific user requirements. CMS users can adopt this tool, the Config Editor, to create their analysis visualizing in real time which are the effects of their actions. They can visualize the structure of their configuration, look at the modules included in the workflow, inspect the dependences existing among the modules and check the data flow. They can visualize at which values parameters are set and change them according to what is required by their analysis task. The integration of common tools in the GUI needed to adopt an object-oriented structure in the Python definition of the PAT tools and the definition of a layer of abstraction from which all PAT tools inherit.

    Lee, Jonas; Kim, Sung Hou

    2009-04-01

    The Protein Data Bank file format is the format most widely used by protein crystallographers and biologists to disseminate and manipulate protein structures. Despite this, there are few user-friendly software packages available to efficiently edit and extract raw information from PDB files. This limitation often leads to many protein crystallographers wasting significant time manually editing PDB files. PDB Editor, written in Java Swing GUI, allows the user to selectively search, select, extract and edit information in parallel. Furthermore, the program is a stand-alone application written in Java which frees users from the hassles associated with platform/operating system-dependent installation and usage. PDB Editor can be downloaded from http://sourceforge.net/projects/pdbeditorjl/.

    Following the FAIR data principles, research data should be Findable, Accessible, Interoperable and Reuseable. Publishing data under these principles requires to assign persistent identifiers to the data and to generate rich machine-actionable metadata. To increase the interoperability, metadata should include shared vocabularies and crosslink the newly published (meta)data and related material. However, structured metadata formats tend to be complex and are not intended to be generated by individual scientists. Software solutions are needed that support scientists in providing metadata describing their data. To facilitate data publication activities of 'GFZ Data Services', we programmed an XML metadata editor that assists scientists to create metadata in different schemata popular in the earth sciences (ISO19115, DIF, DataCite), while being at the same time usable by and understandable for scientists. Emphasis is placed on removing barriers, in particular the editor is publicly available on the internet without registration [1] and the scientists are not requested to provide information that may be generated automatically (e.g. the URL of a specific licence or the contact information of the metadata distributor). Metadata are stored in browser cookies and a copy can be saved to the local hard disk. To improve usability, form fields are translated into the scientific language, e.g. 'creators' of the DataCite schema are called 'authors'. To assist filling in the form, we make use of drop down menus for small vocabulary lists and offer a search facility for large thesauri. Explanations to form fields and definitions of vocabulary terms are provided in pop-up windows and a full documentation is available for download via the help menu. In addition, multiple geospatial references can be entered via an interactive mapping tool, which helps to minimize problems with different conventions to provide latitudes and longitudes. Currently, we are extending the metadata editor

  5. Francis Bacon's concept of objectivity and the idols of the mind.

    Science.gov (United States)

    Zagorin, P

    2001-12-01

    This paper examines the concept of objectivity traceable in Francis Bacon's natural philosophy. After some historical background on this concept, it considers the question of whether it is not an anachronism to attribute such a concept to Bacon, since the word 'objectivity' is a later coinage and does not appear anywhere in his writings. The essay gives reasons for answering this question in the negative, and then criticizes the accounts given of Bacon's understanding of objectivity by Lorraine Daston and Julie Robin Solomon. It argues that this understanding is most directly and fully expressed in his discussion of the idols of the mind. In this connection, the paper notes Bacon's critical attitude to sixteenth-century scepticism and its relevance to the idea of objectivity implicit in his comments on the idols. In conclusion, the paper argues that Bacon was not a pure empiricist and describes the place assigned to theories and hypotheses in his natural philosophy.

  6. Images of trauma: pain, recognition, and disavowal in the works of Frida Kahlo and Francis Bacon.

    2005-01-01

    The role of art in the encounter with trauma and destructiveness is comparatively studied in the works of Frida Kahlo and Francis Bacon as examples of a direct and a more indirect way of dealing with such experiences. A creative product may function intrapsychically as a kind of messenger between dissociated self-states and consciousness, and it may also serve as a witnessing presence in a self-supporting and self-constituting way. Artistic work may thus be used by the artist for an expressive as well as for a protective purpose, as a means of sympathetic participation in painful experience, or as a medium for a view from the outside. The act itself of finding and of making expressive forms at the time of traumatic experience is a remarkable assertion of the human capability to synthesize and to counteract fragmenting dissociative processes.

    If one person can be credited with the creation of the infrastructure of modern anesthesiology, that individual would be Francis Hoeffer McMechan. He has been largely forgotten since his death in 1939 despite his remarkable and enduring accomplishments. McMechan edited the first national journal devoted to anesthesiology, created and managed almost all of the national and regional societies devoted to the specialty between 1912 and his death, and created the first international physician certification as a specialist in anesthesiology. His accomplishments are even more amazing given the severe arthritis that left him wheelchair-bound for almost his entire professional life and denied him the ability to practice anesthesia. Our specialty owes an incredible debt to this largely unknown and unsung hero.

The precious work analysed is the pillow-case used to cover the pillow, on which - according to tradition - St. Francis of Assisi was resting his head when he died. Measurements were performed in order to characterise the embroideries of the two sides and the passementerie in the lateral hems. Several areas, each of the order of two square millimetres, were scanned with a 3 MeV proton external beam of 20 {mu}m size on target, using the external micro-beam facility of our laboratory, with list-mode acquisition. Analysis of elemental maps and spectra from selected homogeneous sub-areas allowed us to extract the quantitative composition of the gilded tape and estimates of its thickness.

Porém, também apresentaram as limitações da teoria econômica, cujas fronteiras vislumbradas pelos autores remetem para a necessidade de avaliar as ações e condutas humanas com teoria moral diferente do utilitarismo. Entendemos que a teoria moral de Adam Smith, esquecida pela história do pensamento econômico, se apresenta como alternativa e, em decorrência, uma ideia promissora para aperfeiçoar o estudo das ações e condutas ditas econômicas.

  12. Unsteady hydraulic simulation of the cavitating part load vortex rope in Francis turbines

    For Francis turbines at part load operation a helical vortex rope is formed due to the swirling nature of the flow exiting the runner. This vortex creates pressure fluctuations which can lead to power swings, and the unsteady loading can lead to fatigue damage of the runner. In the case that the vortex rope cavitates there is the additional risk that hydro-acoustic resonance can occur. It is therefore important to be able to accurately simulate this phenomenon to address these issues. In this paper an unsteady, multi-phase CFD model was used to simulate two part-load operating points, for two different cavitation conditions. The simulation results were validated with test-rig data, and showed very good agreement. These results also served as an input for FEA calculations and fatigue analysis, which are presented in a separate study.

  13. Classics in psychiatry and the law: Francis Wharton on involuntary confessions.

    Science.gov (United States)

    Weiss, Kenneth J

    2012-01-01

    Philadelphia attorney Francis Wharton was a key intellectual figure in linking the sciences of medicine and law. In 1860, he published a monograph on involuntary confessions, which represented the closing chapter of Wharton and Stillé's Treatise on Medical Jurisprudence. He had already published A Monograph on Mental Unsoundness in 1855, the first book of the Treatise in its first edition. Wharton was convinced that many criminals had an inner compulsion to confess or to be caught, explained as divine jurisprudence. His remarks on confessions include a typology spanning psychodynamics to police tactics, using contemporaneous, historical, and literary examples. This remarkable document provides insight into the dynamics of unintended and involuntary confessions and is compatible, in part, with current scholarship. The author contrasts Wharton's schema with those of his English predecessor Jeremy Bentham, the psychoanalyst Theodore Reik, and others, and concludes that it represents an important transition toward a psychological approach to the criminology of confessions.

  14. From political economy to sociology: Francis Galton and the social-scientific origins of eugenics.

    Renwick, Chris

    2011-09-01

    Having coined the word 'eugenics' and inspired leading biologists and statisticians of the early twentieth century, Francis Galton is often studied for his contributions to modern statistical biology. However, whilst documenting this part of his work, historians have frequently neglected crucial aspects of what motivated Galton to establish his eugenics research programme. Arguing that his work was shaped more by social than by biological science, this paper addresses these oversights by tracing the development of Galton's programme, from its roots in a debate about political economy to his appeals for it to be taken up by sociologists. In so doing, the paper not only returns Galton's ideas to their original context but also provides a reason to reflect on the place of the social sciences in history-of-science scholarship.

    Full Text Available This paper presents dynamic modelling of a Francis turbine with a surge tank and the control of a hydro power plant (HPP. Non-linear and linear models include technical parameters and show high similarity to measurement data. Turbine power control with an internal model control (IMC is proposed, based on a turbine fuzzy model. Considering appropriate control responses in the entire area of turbine power, the model parameters of the process are determined from a fuzzy model, which are further included in the internal model controller. The results are compared to a proportional-integral (PI controller tuned with an integral absolute error (IAE objective function, and show an improved response of internal model control.

  16. A world in one dimension: Linus Pauling, Francis Crick and the central dogma of molecular biology.

    2006-01-01

    In 1957, Francis Crick outlined a startling vision of life in which the great diversity of forms and shapes of macromolecules was encoded in the one-dimensional sequence of nucleic acids. This paper situates Crick's new vision in the debates of the 1950s about protein synthesis and gene action. After exploring the reception of Crick's ideas, it shows how they differed radically from a different model of protein synthesis which enjoyed wide currency in that decade. In this alternative model, advocated by Linus Pauling and other luminaries, three-dimensional templates directed the folding of proteins. Even though it was always considered somewhat speculative, this theory was supported by a number of empirical results originating in different experimental systems. It was eventually replaced by a model in which the forms and shapes of macromolecules resulted solely from their amino acid sequence, dramatically simplifying the problem of protein synthesis which Crick was attempting to solve in 1957.

    We performed numerical simulation of flow in a laboratory model of a Francis hydroturbine at startup regimes. Numerical technique for calculating of low frequency pressure pulsations in a water turbine is based on the use of DES (k-ω Shear Stress Transport) turbulence model and the approach of “frozen rotor”. The structure of the flow behind the runner of turbine was analysed. Shows the effect of flow structure on the frequency and intensity of non-stationary processes in the flow path. Two version of the inlet boundary conditions were considered. The first one corresponded measured time dependence of the discharge. Comparison of the calculation results with the experimental data shows the considerable delay of the discharge in this calculation. Second version corresponded linear approximation of time dependence of the discharge. This calculation shows good agreement with experimental results.

    In 1939, a psychologist could become a member of the Southern Society for Philosophy and Psychology (SSPP) automatically with the endorsement of two members, payment of dues, and membership in the American Psychological Association (APA). Non-APA members with endorsements and payment of dues had to be voted in by the membership. In 1940, the rules for admission were changed to eliminate the automatic membership for APA members. Francis Cecil Sumner, the first African American PhD in psychology, qualified for SSPP membership as a member of the APA in 1939, but the SSPP's council delayed his membership and introduced the amendment to its constitution that eliminated Sumner's route to membership. This article examines the circumstances surrounding council's actions and the role that Sumner's application for membership played in it as an example of the role that race and discrimination played in the decision to change the route to SSPP membership for members of the APA.

    Full Text Available In the context of the society in mediatization more and more the social fields are inserted in an ambiance in which borders are constantly tensioned, meaning that social practices are crossed by the logic of other fields, rather than their own place of knowing. It is perceived that the social/political/religious conjuncture interpenetrates with the logic of mediatization, and this phenomenon arouses transformations in all Christianity. The objective of this work is to analyze the circulation of Pope Francis' images in the media which formulate, in the collective imaginary, a mediated totem image of the Pope of embrace or of the welcoming Pope, what adheres to the new media technologies.

    The swirling flow developing in Francis turbine draft tube under part load operation leads to pressure fluctuations usually in the range of 0.2 to 0.4 times the runner rotational frequency resulting from the so-called vortex breakdown. For low cavitation number, the flow features a cavitation vortex rope animated with precession motion. Under given conditions, these pressure fluctuations may lead to undesirable pressure fluctuations in the entire hydraulic system and also produce active power oscillations. For the upper part load range, between 0.7 and 0.85 times the best efficiency discharge, pressure fluctuations may appear in a higher frequency range of 2 to 4 times the runner rotational speed and feature modulations with vortex rope precession. It has been pointed out that for this particular operating point, the vortex rope features elliptical cross section and is animated of a self-rotation. This paper presents an experimental investigation focusing on this peculiar phenomenon, defined as the upper part load vortex rope. The experimental investigation is carried out on a high specific speed Francis turbine scale model installed on a test rig of the EPFL Laboratory for Hydraulic Machines. The selected operating point corresponds to a discharge of 0.83 times the best efficiency discharge. Observations of the cavitation vortex carried out with high speed camera have been recorded and synchronized with pressure fluctuations measurements at the draft tube cone. First, the vortex rope self rotation frequency is evidenced and the related frequency is deduced. Then, the influence of the sigma cavitation number on vortex rope shape and pressure fluctuations is presented. The waterfall diagram of the pressure fluctuations evidences resonance effects with the hydraulic circuit. The time evolution of the vortex rope volume is compared with pressure fluctuations time evolution using image processing. Finally, the influence of the Froude number on the vortex rope shape and

    The growing development of renewable energies combined with the process of privatization, lead to a change of economical energy market strategies. Instantaneous pricings of electricity as a function of demand or predictions, induces profitable peak productions which are mainly covered by hydroelectric power plants. Therefore, operators harness more hydroelectric facilities at full load operating conditions. However, the Francis Turbine features an axi-symmetric rope leaving the runner which may act under certain conditions as an internal energy source leading to instability. Undesired power and pressure fluctuations are induced which may limit the maximum available power output. BC Hydro experiences such constraints in a hydroelectric power plant consisting of four 435 MW Francis Turbine generating units, which is located in Canada's province of British Columbia. Under specific full load operating conditions, one unit experiences power and pressure fluctuations at 0.46 Hz. The aim of the paper is to present a methodology allowing prediction of this prototype's instability frequency from investigations on the reduced scale model. A new hydro acoustic vortex rope model has been developed in SIMSEN software, taking into account the energy dissipation due to the thermodynamic exchange between the gas and the surrounding liquid. A combination of measurements, CFD simulations and computation of eigenmodes of the reduced scale model installed on test rig, allows the accurate calibration of the vortex rope model parameters at the model scale. Then, transposition of parameters to the prototype according to similitude laws is applied and stability analysis of the power plant is performed. The eigenfrequency of 0.39 Hz related to the first eigenmode of the power plant is determined to be unstable. Predicted frequency of the full load power and pressure fluctuations at the unit unstable operating point is found to be in general agreement with the prototype measurements.

    I am very pleased to join the outstanding leadership team for the journal Nuclear Fusion as Scientific Editor. The journal's high position in the field of fusion energy research derives in no small measure from the efforts of the IAEA team in Vienna, the production and marketing of IOP Publishing, the Board of Editors led by its chairman Mitsuru Kikuchi, the Associate Editor for Inertial Confinement Max Tabak and the outgoing Scientific Editor, Paul Thomas. During Paul's five year tenure submissions have grown by over 40%. The usage of the electronic journal has grown year by year with about 300 000 full text downloads of Nuclear Fusion articles in 2011, an impressive figure due in part to the launch of the full 50 year archive. High quality has been maintained while times for peer review and publishing have been reduced and the journal achieved some of the highest impact factors ever (as high as 4.27). The journal has contributed greatly to building the international scientific basis for fusion. I was privileged to serve from 2003 to 2010 as chairman of the Coordinating Committee for the International Tokamak Physics Activity (ITPA) which published in Nuclear Fusion the first ITER Physics Basis (1999) and its later update (2007). The scientific basis that has been developed to date for fusion has led to the construction of major facilities to demonstrate the production of power-plant relevant levels of fusion reactions. We look forward to the journal continuing to play a key role in the international effort toward fusion energy as these exciting major facilities and the various approaches to fusion continue to be developed. It is clear that Nuclear Fusion maintains its position in the field because of the perceived high quality of the submissions, the refereeing and the editorial processes, and the availability and utility of the online journal. The creation of the Nuclear Fusion Prize, led by the Board of Editors chairman Mitsuru Kikuchi, for the most outstanding

    professionals to demonstrate that value in action. Other advantages include the perspectives provided by such special-section authors, editors, and reviewers that draw in a diverse suite of geoscientists and engineers that truly represent the interpretation community. Where there are advantages, there are also disadvantages. First, the vast majority of special-section editors are “new to the job,” never having served on an editorial board of a peer-reviewed scientific journal. The primary objective of this “From the Editor” note is to clarify the roles and responsibilities of this task. Second, many of the selected reviewers may never have had the opportunity to review a paper for publication. They too are new to the job. The August issue of the From the Editor column (Bui et al., 2017) titled “Qualities of a good reviewer” directly addresses this challenge. In this article, we encourage the reviewers to help the authors to construct a quality, well-referenced paper because many of them, too, are new to the job. The third disadvantage is that the special-section format skews the citation-index metrics. Obviously, if the special-section editors identify a good oral presentation and request the author to develop a full-length paper, the chances of acceptance are higher, thus lowering the citation index score. More on this conundrum will be found in the From the Editor column in the February 2018 issue of Interpretation. The remainder of this short article addresses the issues specific to the special-section editors.

    On 1 January, 2004, I assumed the position of Editor-in-Chief of Journal of Physics D: Applied Physics. I will start by saying that I will do my best to justify the confidence of the journal management and publishing staff in my abilities. I was fortunate to have been able to work, as an Editorial Board member, with my predecessor, the previous Editor-in-Chief, Professor Allister Ferguson. Allister has provided a high degree of intellectual stewardship for the journal in the last five years. He has made the job appear a worthy challenge for me. I therefore take this opportunity to thank Allister on behalf of the Editorial Board and publishing staff of the journal. Several other factors contributed to my decision to accept this position. The first is the group of people who actually go about the business of publishing. The Senior Publisher, Nicola Gulley (and her predecessor Sophy Le Masurier); the Managing Editor, Jill Membrey; the Publishing Administrators, Nina Blakesley and Sarah Towell; the Production Editor, Katie Gerrard and their office staff form an amazing group and have managed to make the operation of the journal incredibly efficient. An index of this is the speed with which incoming manuscripts are processed. The average time between the receipt of a manuscript and its web publication, if accepted, is 130 days. This is three to five times shorter than for most other journals. A factor that contributes to this success is a responsive pool of referees that the publishing staff have as a valuable resource. Ultimately, the standard bearers of any journal are the referees. Therefore, a grateful `thank you' is due from all of us at J. Phys. D to all our referees, who diligently perform this honourable task. The Associate Editors of the journal, Professors Lawler, Margaritondo and O'Grady, also provide immense scientific leadership. They help in defining new directions for the journal and in the publishing process. Last, but not least, a remarkable asset of

    On 1 January 2012 I will be assuming the position of Editor-in-Chief of the journal Semiconductor Science and Technology (SST). I am flattered by the confidence expressed in my ability to carry out this challenging job and I will try hard to justify this confidence. The previous Editor-in-Chief, Laurens Molenkamp, University of Würzburg, Germany, has worked tirelessly for the last ten years and has done an excellent job for the journal. Everyone at the journal is profoundly grateful for his leadership and for his achievements In 2012 several new members will join the Editorial Board: Professor Deli Wang (University of California, San Diego) with considerable expertise in semiconductor nanowires, Professor Saskia Fischer (Humboldt University, Berlin, Germany) with a background in semiconductor quantum devices, and Professor Erwin Kessels (Eindhoven University of Technology, Netherlands) with extensive experience in plasma processing of thin films and gate oxides. In particular, I want to express my gratitude to Professor Israel Bar-Joseph (Weizmann Institute of Science, Israel) and Professor Maria Tamargo (The City College of New York, USA), who will leave next year and who have vigorously served the Editorial Board for years. The journal has recently introduced a fast-track option for manuscripts. This option is a high-quality, high-profile outlet for new and important research across all areas of semiconductor research. Authors can expect to receive referee reports in less than 20 days from submission. Once accepted, you can expect the articles to be online within two or three weeks from acceptance and to be published in print in less than a month. Furthermore, all fast-track communications published in 2011 will be free to read for ten years. More detailed information on fast-track publication can be found on the following webpage: http://iopscience.iop.org/0268-1242/page/Fast track communications It is encouraging to see that since the journal introduced pre

  13. Comments on ``Anonymous Reviews'' An Editor's View of Anonymous Reviews

    Science.gov (United States)

    Goff, John A.

    I have read with great interest the recent Forum commentaries in Eos by Myrl Beck, Charles Robinove, Robert Criss, and Anne Hofmeister regarding anonymous reviews. I heartily support their position that anonymous reviews should be avoided. I have not written an anonymous review in ages (and regret the few that I did), and have always appreciated and respected greatly anyone who signs a critical review of one of my own papers. However, I would like to add some perspective from the editorial standpoint. I have served as JGR associate editor for 3 years (never anonymously!), and as Eos editor for seismology and tectonophysics for 4. Over the years, I have rejected a fair number of papers, most of those based on anonymous reviews (fortunately, none of the above commentators was one of them). The vast majority of anonymous reviews I received were well considered. While I would wish that all reviews were signed, I don't think we can summarily dismiss the fear that many would have of enmity and reprisal over a critical review. Some of these fears are likely justified. On more than one occasion, have I witnessed overly aggressive responses on the part of authors to anonymous reviews that I considered to be entirely fair and constructive in their criticisms. I do think we need to do all we can to discourage anonymous reviews, but it will be difficult to completely remove that choice from the process.

  15. An editor for the generation and customization of geometry restraints.

    Moriarty, Nigel W; Draizen, Eli J; Adams, Paul D

    2017-02-01

    Chemical restraints for use in macromolecular structure refinement are produced by a variety of methods, including a number of programs that use chemical information to generate the required bond, angle, dihedral, chiral and planar restraints. These programs help to automate the process and therefore minimize the errors that could otherwise occur if it were performed manually. Furthermore, restraint-dictionary generation programs can incorporate chemical and other prior knowledge to provide reasonable choices of types and values. However, the use of restraints to define the geometry of a molecule is an approximation introduced with efficiency in mind. The representation of a bond as a parabolic function is a convenience and does not reflect the true variability in even the simplest of molecules. Another complicating factor is the interplay of the molecule with other parts of the macromolecular model. Finally, difficult situations arise from molecules with rare or unusual moieties that may not have their conformational space fully explored. These factors give rise to the need for an interactive editor for WYSIWYG interactions with the restraints and molecule. Restraints Editor, Especially Ligands (REEL) is a graphical user interface for simple and error-free editing along with additional features to provide greater control of the restraint dictionaries in macromolecular refinement.

  16. A Generic Metadata Editor Supporting System Using Drupal CMS

    Pan, J.; Banks, N. G.; Leggott, M.

    2011-12-01

    Metadata handling is a key factor in preserving and reusing scientific data. In recent years, standardized structural metadata has become widely used in Geoscience communities. However, there exist many different standards in Geosciences, such as the current version of the Federal Geographic Data Committee's Content Standard for Digital Geospatial Metadata (FGDC CSDGM), the Ecological Markup Language (EML), the Geography Markup Language (GML), and the emerging ISO 19115 and related standards. In addition, there are many different subsets within the Geoscience subdomain such as the Biological Profile of the FGDC (CSDGM), or for geopolitical regions, such as the European Profile or the North American Profile in the ISO standards. It is therefore desirable to have a software foundation to support metadata creation and editing for multiple standards and profiles, without re-inventing the wheels. We have developed a software module as a generic, flexible software system to do just that: to facilitate the support for multiple metadata standards and profiles. The software consists of a set of modules for the Drupal Content Management System (CMS), with minimal inter-dependencies to other Drupal modules. There are two steps in using the system's metadata functions. First, an administrator can use the system to design a user form, based on an XML schema and its instances. The form definition is named and stored in the Drupal database as a XML blob content. Second, users in an editor role can then use the persisted XML definition to render an actual metadata entry form, for creating or editing a metadata record. Behind the scenes, the form definition XML is transformed into a PHP array, which is then rendered via Drupal Form API. When the form is submitted the posted values are used to modify a metadata record. Drupal hooks can be used to perform custom processing on metadata record before and after submission. It is trivial to store the metadata record as an actual XML file

  19. On the physical mechanisms governing self-excited pressure surge in Francis turbines

    Müller, A; Favrel, A; Landry, C; Yamamoto, K; Avellan, F

    2014-01-01

    The required operating range for hydraulic machines is continually extended in an effort to integrate renewable energy sources with unsteady power outputs into the existing electrical grid. The off-design operation however brings forth unfavorable flow patterns in the machine, causing dynamic problems involving cavitation, which may represent a limiting factor to the energy production. In Francis turbines it is observed that the self-excited oscillation of a vortex rope in the draft tube cone prevents the delivery of maximum power when required. This phenomenon is referred to as full load pressure surge and has been the object of extensive research during the past decades. Several contributions deepened its understanding through measurement and simulation of the local flow properties and the global stability parameters. The draft tube pressure level and the runner outlet swirl are identified as key variables in the modelling of the vortex rope dynamics. Recently, a cyclic appearance of blade cavitation has been observed at overload conditions in a multiphase numerical simulation coupling the runner and the draft tube. From the analysis of the simulation it becomes obvious that the cyclic appearance of blade cavitation has a direct effect on the runner outlet swirl, thus introducing an additional interaction mechanism that is not accounted for in formerly published models. For the presented work, the results of this numerical study are confirmed experimentally on a reduced scale model of a Francis turbine. Several wall pressure measurements in the draft tube cone are performed, together with high speed visualizations of the vortex rope and the blade cavitation. The flow swirl is calculated based on Laser Doppler Velocimetry measurements. A possible mechanism explaining the coupling between the self-excited pressure and vortex rope oscillation and the cyclic appearance of the blade cavitation is proposed. Furthermore, the streamwise propagation speed of the flow

    Hydropower plants may be required to operate in synchronous condenser mode in order to supply reactive power to the grid for compensating the fluctuations introduced by the intermittent renewable energies such wind and solar. When operating in this mode, the tail water in the Francis turbine or pump-turbine is depressed below the runner by injecting pressurized air in order to spin in air to reduce the power consumption. Many air-water interaction phenomena occur in the machine causing air losses and a consequent power consumption to recover the air lost. In this paper, the experimental investigation of the sloshing motion in the cone of a dewatered Francis turbine performed by image visualization and pressure measurements is presented. The developed image post processing method for identifying the amplitude and frequency of the oscillation of the free surface is described and the results obtained are illustrated and discussed.

    Full Text Available As the key component of a hydroelectric power generation system, hydraulic turbine plays a decisive role in the overall performance of the system. There are many sandy rivers in the world, and turbines working in these rivers are seriously damaged. Therefore, the research of flow in sandy water has great theoretical significance and practical value. Based on the specific hydrological conditions of a hydropower station, the solid–liquid two-phase flow in the whole flow passage of a Francis turbine with splitter blades in sandy water was numerically studied. A geometric model of the whole flow passage of the Francis turbine was established on the basis of given design parameters. The solid–liquid two-phase turbulent flows in Francis turbine runner under three different loads were numerically analyzed by using this model. The three different loads are as follows: Condition 1: single unit with 1/4 load, Condition 2: single unit with 1/2 load, and Condition 3: single unit with full load. The distributions of pressure and sand concentration on the leading side and the suction side of the runner blades, as well as the velocity vector distribution of water and sand on the horizontal section of the runner, were obtained under different load conditions. Therefore, the damages to various flow passage components by sand can be qualitatively predicated under various conditions. To guarantee the safety and stability of the unit, the adverse conditions shall be avoided, which can provide certain reference for plant operation.

    Since natural textiles usually originate from short-lived organisms, they can represent a useful material to date samples from historical periods with a good accuracy. In this work, we present a set of radiocarbon measurements on medieval textile relics: two woollen habits and a pillow traditionally associated with St. Francis of Assisi, the saint patron of Italy. The strategy in choosing samples for radiocarbon dating is first discussed and the procedures for measurements - performed at the 3 MV Tandetron accelerator of Laboratorio di Tecniche Nucleari per i Beni Culturali (LABEC), Florence - are described; AMS results for the two frocks showed that only one of them, presently kept in the church of St. Francis in Cortona, is compatible with the Saint's period of life, as is the pillow also kept in Cortona. Another frock attributed to St. Francis appears to date from at least 80 years after his death. However, the goal of these measurements was not a bare authentication/disconfirmation of the relics; they just represent an example of how scientific analysis can integrate with humanistic studies. Indeed, AMS results, combined with a thorough analysis of the textiles typologies, confirmed the historical hypotheses based on documentary studies and on tradition. The overall conclusions contributed to the decisions taken for conservation, and have as a whole enhanced the religious importance of the relics.

  6. Expected load spectra of prototype Francis turbines in low-load operation using numerical simulations and site measurements

    Eichhorn, M.; Taruffi, A.; Bauer, C.

    2017-04-01

    The operators of hydropower plants are forced to extend the existing operating ranges of their hydraulic machines to remain competitive on the energy market due to the rising amount of wind and solar power. Faster response times and a higher flexibility towards part- and low-load conditions enable a better electric grid control and assure therefore an economic operation of the power plant. The occurring disadvantage is a higher dynamic excitation of affected machine components, especially Francis turbine runners, due to pressure pulsations induced by unsteady flow phenomena (e.g. draft tube vortex ropes). Therefore, fatigue analysis becomes more important even in the design phase of the hydraulic machines to evaluate the static and dynamic load in different operating conditions and to reduce maintenance costs. An approach including a one-way coupled fluid-structure interaction has been already developed using unsteady CFD simulations and transient FEM computations. This is now applied on two Francis turbines with different specific speeds and power ranges, to obtain the load spectra of both machines. The results are compared to strain gauge measurements on the according Francis turbines to validate the overall procedure.

  7. Francis Bacon and the "Interpretation of Nature" in the late Renaissance.

    Science.gov (United States)

    Serjeantson, Richard

    2014-12-01

    The "interpretation of nature" (interpretatio naturae) is the leading idea in Francis Bacon's natural philosophy. But by contrast with his ideas about method, induction, or experiment, the significance of the "interpretation of nature" has received very little scholarly attention. This essay tests the originality of Bacon's idea by means of a focused survey of existing forms of Renaissance natural knowledge-Aristotelian and anti-Aristotelian natural philosophy, Galenic and Paracelsian medicine, natural magic, physiognomy, natural history-before turning to consider the much more prominent place of "interpretation" in the fields of Renaissance logic, revealed and natural theology, and law. It finds that Bacon's application of the idea of "interpretation" to nature was highly original, but also that certain important aspects of his conception have analogies in Renaissance civil law. The essay concludes by exploring the implications of these findings for a recent body of scholarship in the history of the sciences that invokes the notion of the "interpretation of nature" to characterize pre-Baconian natural philosophy more generally.

    2013-01-01

    In this paper we discuss the work of Francis Bacon in the context of his declared aim of giving a “visual shock.”We explore what this means in terms of brain activity and what insights into the brain's visual perceptive system his work gives. We do so especially with reference to the representation of faces and bodies in the human visual brain. We discuss the evidence that shows that both these categories of stimuli have a very privileged status in visual perception, compared to the perception of other stimuli, including man-made artifacts such as houses, chairs, and cars. We show that viewing stimuli that depart significantly from a normal representation of faces and bodies entails a significant difference in the pattern of brain activation. We argue that Bacon succeeded in delivering his “visual shock” because he subverted the normal neural representation of faces and bodies, without at the same time subverting the representation of man-made artifacts.

  9. The mine and the furnace: Francis Bacon, Thomas Russell, and early Stuart mining culture.

    2009-01-01

    Notwithstanding Francis Bacon's praise for the philosophical role of the mechanical arts, historians have often downplayed Bacon's connections with actual artisans and entrepreneurs. Addressing the specific context of mining culture, this study proposes a rather different picture. The analysis of a famous mining metaphor in The Advancement of Learning shows us how Bacon's project of reform of knowledge could find an apt correspondence in civic and entrepreneurial values of his time. Also, Bacon had interesting and so far unexplored links with the early modern English mining enterprises, like the Company of Mineral and Battery Works, ofwhich he was a shareholder. Moreover, Bacon's notes in a private notebook, Commentarius Solutus, and records of patents of invention, allow us to start grasping Bacon's connections with the metallurgist and entrepreneur Thomas Russell. Lastly, this paper argues that, to fully understand Bacon's links with the world of Stuart technicians and entrepreneurs, it is necessary to consider a different and insufficiently studied aspect of Bacon's interests, namely his work as patents referee while a Commissioner of Suits.

    High Cycle Fatigue (HCF) plays an important role in Francis runner reliability. This paper presents a model in which reliability is defined as the probability of not exceeding a threshold above which HCF contributes to crack propagation. In the context of combined Low Cycle Fatigue (LCF) and HCF loading, the Kitagawa diagram is used as the limit state threshold for reliability. The reliability problem is solved using First-Order Reliability Methods (FORM). A study case is proposed using in situ measured strains and operational data. All the parameters of the reliability problem are based either on observed data or on typical design specifications. From the results obtained, we observed that the uncertainty around the defect size and the HCF stress range play an important role in reliability. At the same time, we observed that expected values for the LCF stress range and the number of LCF cycles have a significant influence on life assessment, but the uncertainty around these values could be neglected in the reliability assessment.

    Sleep-related hypermotor epilepsy (SHE) is characterized by short-lasting seizures patterned by repetitive and stereotyped motor events in the same person. In autosomal dominant SHE, genetic factors play a well-known key role. In The Expression of Emotions in Man and Animals, Charles Darwin quotes a plausible example of SHE illustrated by his cousin Sir Francis Galton: "the gentleman…lay fast asleep on his back in bed, raising his right arm slowly in front of his face, up to his forehead, and then dropping it with a jerk, so that the wrist fell heavily on the bridge of his nose. The trick did not occur every night, but occasionally, and was independent of any ascertained cause. Sometimes it was repeated incessantly for an hour or more." Similar manifestations during sleep occurred also in the patient's son and granddaughter, suggesting an autosomal inheritance without sex relationship. Differential diagnosis with REM behavior disorder and other parasomnias is discussed. To our knowledge, this could be the first description of a stereotyped SHE pattern with genetic transmission. © 2017 American Academy of Neurology.

    This year celebrates the 200(th) aniversary of the birth of Charles Darwin, best known for his theory of evolution summarized in On the Origin of Species. Less well known is that, in the second half of his life, Darwin's major scientific focus turned towards plants. He wrote several books on plants, the next-to-last of which, The Power of Movement of Plants, published together with his son Francis, opened plants to a new view. Here we amplify the final sentence of this book in which the Darwins proposed that: "It is hardly an exaggeration to say that the tip of the radicle thus endowed [with sensitivity] and having the power of directing the movements of the adjoining parts, acts like the brain of one of the lower animals; the brain being seated within the anterior end of the body, receiving impressions from the sense-organs, and directing the several movements." This sentence conveys two important messages: first, that the root apex may be considered to be a 'brain-like' organ endowed with a sensitivity which controls its navigation through soil; second, that the root apex represents the anterior end of the plant body. In this article, we discuss both these statements.

    Hydraulic turbines are operated over an extended operating range to meet the real time electricity demand. Turbines operated at part load have flow parameters not matching the designed ones. This results in unstable flow conditions in the runner and draft tube developing low frequency and high amplitude pressure pulsations. The unsteady pressure pulsations affect the dynamic stability of the turbine and cause additional fatigue. The work presented in this paper discusses the flow field investigation of a high head model Francis turbine at part load: 50% of the rated load. Numerical simulation of the complete turbine has been performed. Unsteady pressure pulsations in the vaneless space, runner, and draft tube are investigated and validated with available experimental data. Detailed analysis of the rotor stator interaction and draft tube flow field are performed and discussed. The analysis shows the presence of a rotating vortex rope in the draft tube at the frequency of 0.3 times of the runner rotational frequency. The frequency of the vortex rope precession, which causes severe fluctuations and vibrations in the draft tube, is predicted within 3.9% of the experimental measured value. The vortex rope results pressure pulsations propagating in the system whose frequency is also perceive in the runner and upstream the runner.

    At full and over load operating points, some Francis turbines experience strong self-excited pressure and power oscillations. These oscillations are occuring due to the hydrodynamic instability of the cavitating fluid flow. In many cases, the amplitude of such pulsations may be reduced substantially during the turbine operation by the air injection/ admission below the runner. Such an effect is investigated numerically in the present work. To this end, the hybrid one-three-dimensional model of the flow of the mixture "liquid-vapor" in the duct of a hydroelectric power station, which was proposed previously by the present authors, is augmented by the second gaseous component — the noncondensable air. The boundary conditions and the numerical method for solving the equations of the model are described. To check the accuracy of computing the interface "liquid-gas", the numerical method was applied at first for solving the dam break problem. The algorithm was then used for modeling the flow in a hydraulic turbine with air injection below the runner. It is shown that with increasing flow rate of the injected air, the amplitude of pressure pulsations decreases. The mechanism of the flow structure alteration in the draft tube cone has been elucidated, which leads to flow stabilization at air injection.

    The inter-blade vortex in a Francis turbine becomes one of the main hydraulic factors that are likely to cause blade erosion at deep part load operating conditions. However, the causes and the mechanism of inter-blade vortex are still under investigation according to present researches. Thus the causes of inter-blade vortex and the effect of different hydraulic parameters on the inter-blade vortex are investigated experimentally. The whole life cycle of the inter-blade vortex is observed by a high speed camera. The test results illustrate the whole life cycle of the inter-blade vortex from generation to separation and even to fading. It is observed that the inter-blade vortex becomes stronger with the decreasing of flow and head, which leads to pressure fluctuation. Meanwhile, the pressure fluctuations in the vane-less area and the draft tube section become stronger when inter-blade vortices exist in the blade channel. The turbine will be damaged if operating in the inter-blade vortex zone, so its operating range must be far away from that zone. This paper reveals the main cause of the inter-blade vortex which is the larger incidence angle between the inflow angle and the blade angle on the leading edge of the runner at deep part load operating conditions.

    The high specific speed Francis turbine is still suitable alternative for refurbishment of older hydro power plants with lower heads and worse cavitation conditions. In the paper the design process of such kind of turbine together with the results comparison of homological model tests performed in hydraulic laboratory of ČKD Blansko Engineering is introduced. The turbine runner was designed using the optimization algorithm and considering the high specific speed hydraulic profile. It means that hydraulic profiles of the spiral case, the distributor and the draft tube were used from a Kaplan turbine. The optimization was done as the automatic cycle and was based on a simplex optimization method as well as on a genetic algorithm. The number of blades is shown as the parameter which changes the resulting specific speed of the turbine between n s =425 to 455 together with the cavitation characteristics. Minimizing of cavitation on the blade surface as well as on the inlet edge of the runner blade was taken into account during the design process. The results of CFD analyses as well as the model tests are mentioned in the paper

    Full Text Available The public profile of the Roman Catholic bishops of the United States results not simply from their own interventions in political life, but from the broad array of actions and actors within “public Catholicism” broadly conceived. This article assesses the contemporary profile of the American bishops from this broad angle, particularly in light of new dynamics under the papacy of Francis I. It does so by documenting public Catholicism’s presence in ecclesial institutions, other public institutions, and lay-centered social movements (particularly faith-based community organizing and via a case study of the healthcare reform debate around the State Children’s Health Insurance Program and the Affordable Care Act. Cultural and institutional factors shaping Catholic public presence are analyzed in three dimensions of social life: institutional leadership; authority dynamics within the Church; and the culture of prayer, spirituality, and worship in parishes. Finally, the conclusion discusses the key dynamics likely to shape the future of public Catholicism in America.

    2017-01-01

    Numerical simulation of the Francis-99 hydroturbine with correlation to experimental measurements are presented. Steady operation of the hydroturbine is analyzed at three operating conditions: the best efficiency point (BEP), high load (HL), and part load (PL). It is shown that global quantities such as net head, discharge and efficiency are well predicted. Additionally, time-averaged velocity predictions compare well with PIV measurements obtained in the draft tube immediately downstream of the runner. Differences in vortex rope structure between operating points are discussed. Unsteady operation of the hydroturbine from BEP to HL and from BEP to PL are modeled. It is shown that simulation methods used to model the steady operation produce predictions that correlate well with experiment for transient operation. Time-domain unsteady simulation is used for both steady and unsteady operation. The full-fidelity geometry including all components is meshed using an unstructured polyhedral mesh with body-fitted prism layers. Guide vane rotation for transient operation is imposed using fully-conservative, computationally efficient mesh morphing. The commercial solver STAR-CCM+ is used for all portions of the analysis including meshing, solving and post-processing.

  20. Applying Turbulence Models to Hydroturbine Flows: A Sensitivity Analysis Using the GAMM Francis Turbine

    Turbulence models are generally developed to study common academic geometries, such as flat plates and channels. Creating quality computational grids for such geometries is trivial, and allows stringent requirements to be met for boundary layer grid refinement. However, engineering applications, such as flow through hydroturbines, require the analysis of complex, highly curved geometries. To produce body-fitted grids for such geometries, the mesh quality requirements must be relaxed. Relaxing these requirements, along with the complexity of rotating flows, forces turbulence models to be employed beyond their developed scope. This study explores the solution sensitivity to boundary layer grid quality for various turbulence models and boundary conditions currently implemented in OpenFOAM. The following models are resented: k-omega, k-omega SST, k-epsilon, realizable k-epsilon, and RNG k-epsilon. Standard wall functions, adaptive wall functions, and sub-grid integration are compared using various grid refinements. The chosen geometry is the GAMM Francis Turbine because experimental data and comparison computational results are available for this turbine. This research was supported by a grant from the DoE and a National Defense Science and Engineering Graduate Fellowship.

  1. A Parametric Study of Unsteady Rotor-Stator Interaction in a Simplified Francis Turbine

    CFD analysis is becoming a critical stage in the design of hydroturbines. However, its capability to represent unsteady flow interactions between the rotor and stator (which requires a 360-degree, mesh-refined model of the turbine passage) is hindered. For CFD to become a more effective tool in predicting the performance of a hydroturbine, the key interactions between the rotor and stator need to be understood using current numerical methods. As a first step towards evaluating this unsteady behavior without the burden of a computationally expensive domain, the stator and Francis-type rotor blades are reduced to flat plates. Local and global variables are compared using periodic, semi-periodic, and 360-degree geometric models and various turbulence models (k-omega, k-epsilon, and Spalart-Allmaras). The computations take place within the OpenFOAM® environment and utilize a general grid interface (GGI) between the rotor and stator computational domains. The rotor computational domain is capable of dynamic rotation. The results demonstrate some of the strengths and limitations of utilizing CFD for hydroturbine analysis. These case studies will also serve as tutorials to help others learn how to use CFD for turbomachinery. This research is funded by a grant from the DOE.

  2. Experimental Investigation on the Characteristics of Hydrodynamic Stabilities in Francis Hydroturbine Models

    2014-03-01

    Full Text Available This paper presents an experimental investigation of flow phenomena related to the characteristic frequencies of pressure fluctuation in Francis hydroturbine models. The experiments were carried out on two test rigs with two model runners having hydraulic similarities. Flow field around the guide vanes was measured with a particle image velocimetry (PIV on the first PIV test rig. Flow structures at the inlet region of runner and in draft tube at different operating conditions were visualized on another hydrodynamic test rig. Analyses of dominant frequency of unsteady hydraulic behaviors in the tested hydroturbines were performed. It was observed that the main frequency of flow over the guide vanes and the dominant frequency of channel vortex equal the blade passing frequency; the dominant frequency of flow separation at the suction side of blade inlet equals the vane passing frequency; the vortex rope in the draft tube displays a low-frequency nature. The flow instabilities and fluctuations directly influence the running of hydroturbine, thus these experimental results could provide important evidence for the stability study of a real hydroturbine.

    2017-01-01

    Full Text Available The paper reports on some results of the experimental study of flow and pressure pulsations in a laboratory model of the draft tube (DT of Francis-99 hydro-turbine over a broad range of operating regimes. Velocity distributions at the model inlet varied within 866 modes of the turbine load conditions, including those with maximum coherent pressure pulsations on the model walls. The contact and non-contact methods were used to measure pressure pulsations on the model walls using acoustic sensors and to measure the averaged velocity distribution with a laser Doppler anemometer “LAD-06i”. Analysis of the results have showed that in the model cone there are flow modes with forming of precessing vortex cores, accompanied by a sharp increase in the amplitude of coherent pressure pulsations on the wall and the velocity field rearrangement. It is shown that the vortex core starts forming with an increase in the integral parameter of swirl up to S>0.5. A novelty of the work is the combination of the rapid prototyping (3-d printing of the inflow swirl generators and computerized measurement techniques that makes it possible to acquire rapidly a large amount of experimental data for a variety of designs and operating conditions. The results can provide insight into the effect of various design and operating parameters on the flow physics, as well as serve for verification of the numerical simulations.

  4. Deciphering the language of nature: cryptography, secrecy, and alterity in Francis Bacon.

    Clody, Michael C

    2011-01-01

    The essay argues that Francis Bacon's considerations of parables and cryptography reflect larger interpretative concerns of his natural philosophic project. Bacon describes nature as having a language distinct from those of God and man, and, in so doing, establishes a central problem of his natural philosophy—namely, how can the language of nature be accessed through scientific representation? Ultimately, Bacon's solution relies on a theory of differential and duplicitous signs that conceal within them the hidden voice of nature, which is best recognized in the natural forms of efficient causality. The "alphabet of nature"—those tables of natural occurrences—consequently plays a central role in his program, as it renders nature's language susceptible to a process and decryption that mirrors the model of the bilateral cipher. It is argued that while the writing of Bacon's natural philosophy strives for literality, its investigative process preserves a space for alterity within scientific representation, that is made accessible to those with the interpretative key.

  5. From medicine to natural philosophy: Francis Hauksbee's way to the air-pump.

    Francis Hauksbee (1660-1713) is well known for his double-barrelled air-pump. However, the origin of this pump, and Hauksbee's background, are often described as a mystery. This text seeks to dispel the riddle. It is argued that Hauksbee's competence as an exceptional maker of air-pumps was developed between 1699 and 1703 as a result of his experiences with the construction, manufacturing and sale of cupping-glasses. His cupping utensils embodied a new design, where syringes were used to evacuate the glasses, instead of the traditional way by fire or mouth suction. These syringes, which in fact were small air-pumps, were perfected between 1699 and 1701. A larger syringe, introduced in 1701, served as a transition from the cupping-syringe to his first air-pump for use in natural philosophy. This syringe was described as a 'combined engine', which could serve as an air-pump, a condensing engine and a syringe for injecting air, wax or mercury into pathological specimens. Hauksbee's first air-pump was a single-barrelled model introduced in 1702, based on the combined engine. Its various features, such as easy and convenient leak-tightening, exact pressure measurements by an in-built barometer and an air-inlet function for readmission of air into the receiver, are discussed. Finally, it is shown that these activities gave Hauksbee the reputation of being an outstanding instrument-maker, years before the double-barrelled air-pump was in sight.

    Full load pressure surge limits the operating range of hydro-electric generating units by causing significant power output swings and by compromising the safety of the plant. It appears during the off-design operation of hydraulic machines, which is increasingly required to regulate the broad integration of volatile renewable energy sources into the existing power network. The underlying causes and governing physical mechanisms of this instability were investigated in the frame of a large European research project and this paper documents the main findings from two experimental campaigns on a reduced scale model of a Francis turbine. The multi-phase flow in the draft tube is characterized by Particle Image Velocimetry, Laser Doppler Velocimetry and high-speed visualizations, along with synchronized measurements of the relevant hydro-mechanical quantities. The final result is a comprehensive overview of how the unsteady draft tube flow and the mechanical torque on the runner shaft behave during one mean period of the pressure oscillation, thus defining the unstable fluid-structure interaction responsible for the power swings. A discussion of the root cause is initiated, based on the state of the art. Finally, the latest results will enable a validation of recent RANS flow simulations used for determining the key parameters of hydro-acoustic stability models.

  7. Investigation of a High Head Francis Turbine at Runaway Operating Conditions

    2016-03-01

    Full Text Available Hydraulic turbines exhibit total load rejection during operation because of high fluctuations in the grid parameters. The generator reaches no-load instantly. Consequently, the turbine runner accelerates to high speed, runaway speed, in seconds. Under common conditions, stable runaway is only reached if after a load rejection, the control and protection mechanisms both fail and the guide vanes cannot be closed. The runner life is affected by the high amplitude pressure loading at the runaway speed. A model Francis turbine was used to investigate the consequences at the runaway condition. Measurements and simulations were performed at three operating points. The numerical simulations were performed using standard k-ε, k-ω shear stress transport (SST and scale-adaptive simulation (SAS models. A total of 12.8 million hexahedral mesh elements were created in the complete turbine, from the spiral casing inlet to the draft tube outlet. The experimental and numerical analysis showed that the runner was subjected to an unsteady pressure loading up to three-times the pressure loading observed at the best efficiency point. Investigates of unsteady pressure pulsations at the vaneless space, runner and draft tube are discussed in the paper. Further, unsteady swirling flow in the blade passages was observed that was rotating at a frequency of 4.8-times the runaway runner angular speed. Apart from the unsteady pressure loading, the development pattern of the swirling flow in the runner is discussed in the paper.

    Sudden pressure increases in the penstock or spiral case of a hydraulic turbine are the effect of sudden flow variation that occur during transient processes of type opening / closing or load rejection of the hydro unit. The consequence of the pressure rise in the spiral case and penstock is the water hammer phenomenon, whose effects can be devastating in some cases, up to breaking pipes and calamities produced in the area. This paper aims to analyze the method of calculation of the maximum pressure values that might occur in load rejection situations to a hydraulic turbine, in spiral case and in penstock, conditioned by the limiting of the values of the over speed and measures of limiting the increase in pressure in conjunction with limiting the increase in speed in these specific processes. As an example, we studied and analyzed the situation of a hydroelectric power plant equipped with a 7.8 MW Francis turbine without pressure regulator and the inflow surge. The results of analytical calculation overlaid on the experimental measurements performed during the performance tests of the hydro unit lead to the conclusion that the calculation algorithm proposed has been chosen correctly and the 2-stage closing law of the wicket gate promoted in this case is effective in such situations.

    In the present paper numerical investigations of a complete high head Francis turbine comprehensive of a spiral casing, stay and guide vanes and draft tube have been performed at three operating conditions, namely at part load (PL), best efficiency point (BEP), and high load (HL). The main target of the investigations is to assess the prediction accuracy of a reduced domain of the complete turbine using a novel mixing-plane formulation. The computational domain is simplified simulating one single passage of the runner, thus assuming rotational periodicity and steady state conditions. The results were compared with experimental data published by the workshop organization. All CFD simulations were performed at model scale with an in-house adapted, 3D, unstructured, object-oriented finite volume code based on the OpenFOAM-V2.2 framework and designed to solve steady-state incompressible RANS-Equations. The pressure-based solver uses a SIMPLE-C like algorithm and is capable of handling multiple references of frame (MRF). The influence of the turbulence has been considered applying the shear-stress transport model (SST). Full second order upwind scheme for advection discretization has been used for all computations

    1992-01-01

    Software development is widely considered to be a bottleneck in the development of complex systems, both in terms of development and in terms of maintenance of deployed systems. Cost of software development and maintenance can also be very high. One approach to reducing costs and relieving this bottleneck is increasing the reuse of software designs and software components. A method for achieving such reuse is a software parts composition system. Such a system consists of a language for modeling software parts and their interfaces, a catalog of existing parts, an editor for combining parts, and a code generator that takes a specification and generates code for that application in the target language. The Advanced Software Development Workstation is intended to be an expert system shell designed to provide the capabilities of a software part composition system.

    The article considers available options to educate science editors in the fast-transforming digital environment. There is no single course or resource that can cover their constantly changing and diversifying educational needs. The involvement in research, writing, and reviewing is important for gaining editing skills, but that is not all. Membership in editorial associations and access to updated scholarly information in the field are mandatory for maintaining editorial credentials. Learned associations offer access to a few widely-recognized periodicals. There are also formal training courses covering issues in science writing and ethical editing, but no high-level evidence data exist to promote any of these. Networking with like-minded specialists within the global and regional editorial associations seems a useful strategy to upgrade editorial skills and resolve problems with the quality control and digitization of scholarly periodicals.

    As the incoming editor of Global Biogeochemical Cycles, I would like to introduce myself and my ideas for the journal to Eos readers and to current and potential GBC authors. I've had a somewhat ``roaming'' scientific evolution, coming from ``straight'' chemistry through hard-rock geochemistry to chemical oceanography, the field in which I did my Ph.D. I taught marine chemistry at Florida State University for a number of years, and developed an interest in ocean/atmosphere interactions and atmospheric chemistry. In 1987 I took on my present job at the Max Planck Institute for Chemistry, in Mainz, Germany, and, after leaving the seacoast, my interests shifted to interactions between the terrestrial biosphere and atmosphere, including the role of vegetation fires. My present focus is on the role of biogenic aerosols and biomass smoke in regulating cloud properties and influencing climate.

    TIn the autumn of 2010 I became the Editor-in Chief of European Journal of Physics (EJP). EJP is a place for teachers, instructors and professors to exchange their views on teaching physics at university level and share their experience. It is general opinion that no good research is possible without connection with good, high-quality teaching, at the university level in particular. Therefore excellence in physics teaching is important to the physics community. European Journal of Physics is proud of its contribution to achieving this goal. As Editor-in-Chief, I will continue to work to this general objective of the journal. We will publish articles on specific topics in physics, stressing originality of presentation and suitability for use in students'laboratories, lectures and physics teaching in general. We will also publish more pedagogical papers presenting the achievements of particular teaching methods. In addition, we will continue to publish special sections on particular areas of physics, as well as the annual special section on physics competitions. European Journal of Physics is in good shape. Due to the work of the previous editors and the publisher, the readership is high and growing steadily, and many excellent papers are being submitted and published. I hope that this positive trend for the journal will continue, and I will do my best to keep to this high standard. A few words about myself. I work in the Institute of Physics in Warsaw, Poland. My main research interests are in theoretical quantum optics and I have published about 80 research papers on this topic. For many years I was involved in teaching physics at university and in high school. I am a co-author of a textbook on physics for high-school students and of a problem book in quantum mechanics. For the last ten years, I have been involved in the International Physics Olympiad and over the last few years I have been a member of the Editorial Board of European Journal of Physics.

  6. Computation and analysis of cavitating flow in Francis-class hydraulic turbines

    Science.gov (United States)

    Leonard, Daniel J.

    Hydropower is the most proven renewable energy technology, supplying the world with 16% of its electricity. Conventional hydropower generates a vast majority of that percentage. Although a mature technology, hydroelectric generation shows great promise for expansion through new dams and plants in developing hydro countries. Moreover, in developed hydro countries, such as the United States, installing generating units in existing dams and the modern refurbishment of existing plants can greatly expand generating capabilities with little to no further impact on the environment. In addition, modern computational technology and fluid dynamics expertise has led to substantial improvements in modern turbine design and performance. Cavitation has always presented a problem in hydroturbines, causing performance breakdown, erosion, damage, vibration, and noise. While modern turbines are usually designed to be cavitation-free at their best efficiency point, due to the variable demand of the energy market it is fairly common to operate at off-design conditions. Here, cavitation and its deleterious effects are unavoidable, and hence, cavitation is a limiting factor on the design and operation of these turbines. Multiphase Computational Fluid Dynamics (CFD) has been used in recent years to model cavitating flow for a large range of problems, including turbomachinery. However, CFD of cavitating flow in hydroturbines is still in its infancy. This dissertation presents steady-periodic Reynolds-averaged Navier-Stokes simulations of a cavitating Francis-class hydroturbine at model and prototype scales. Computational results of the reduced-scale model and full-scale prototype, undergoing performance breakdown, are compared with empirical model data and prototype performance estimations based on standard industry scalings from the model data. Mesh convergence of the simulations is also displayed. Comparisons are made between the scales to display that cavitation performance breakdown

    Nobody is better suited to describe data than the scientist who created it. This description about a data is called Metadata. In general terms, Metadata represents the who, what, when, where, why and how of the dataset [1]. eXtensible Markup Language (XML) is the preferred output format for metadata, as it makes it portable and, more importantly, suitable for system discoverability. The newly developed ORNL Metadata Editor (OME) is a Web-based tool that allows users to create and maintain XML files containing key information, or metadata, about the research. Metadata include information about the specific projects, parameters, time periods, and locations associated with the data. Such information helps put the research findings in context. In addition, the metadata produced using OME will allow other researchers to find these data via Metadata clearinghouses like Mercury [2][4]. OME is part of ORNL s Mercury software fleet [2][3]. It was jointly developed to support projects funded by the United States Geological Survey (USGS), U.S. Department of Energy (DOE), National Aeronautics and Space Administration (NASA) and National Oceanic and Atmospheric Administration (NOAA). OME s architecture provides a customizable interface to support project-specific requirements. Using this new architecture, the ORNL team developed OME instances for USGS s Core Science Analytics, Synthesis, and Libraries (CSAS&L), DOE s Next Generation Ecosystem Experiments (NGEE) and Atmospheric Radiation Measurement (ARM) Program, and the international Surface Ocean Carbon Dioxide ATlas (SOCAT). Researchers simply use the ORNL Metadata Editor to enter relevant metadata into a Web-based form. From the information on the form, the Metadata Editor can create an XML file on the server that the editor is installed or to the user s personal computer. Researchers can also use the ORNL Metadata Editor to modify existing XML metadata files. As an example, an NGEE Arctic scientist use OME to register

    Full Text Available Este texto se ocupa de um exame, em caráter introdutório, das relações entre a reflexão de Bacon acerca das limitações de nossas faculdades e o ceticismo filosófico - um tema pouco considerado pela literatura mais recente, a despeito das muitas referências a tal filosofia. Ainda que, à primeira vista, tais referências possam parecer vagas e imprecisas, pensamos que um exame adequado de algumas delas pode revelar, não apenas a importância do tema para a compreensão de aspectos do seu próprio empreendimento, mas o interesse de Bacon pela literatura cética contemporânea. As peculiaridades de sua própria interpretação, por sua vez, parecem antecipar traços do modo como essa filosofia foi compreendida por filósofos posteriores, como Hume.This text focuses, in a preliminary way, on the relations between Francis Bacon's reflections on the limits of our cognitive faculties and philosophical skepticism, a theme not much considered by most of recent commentaries, in spite of Bacon's own explicit and numerous allusions to this philosophy. Even if these allusions seem at first sight somewhat loose and not very sharp, some of them reveal, we think, not only its relevance for understanding of some aspects of his own enterprise, but also Bacon's attention to the skeptical literature produced on the period. Moreover, the particularities of his own interpretation of skepticism seem to anticipate important features of the way this philosophy was understood by later philosophers as Hume.

  10. Two-phase simulations of the full load surge in Francis turbines

    Science.gov (United States)

    Wack, J.; Riedelbauch, S.

    2016-11-01

    At off-design conditions, Francis turbines experience cavitation which may reduce the power output and can cause severe damage in the machine. Certain conditions can cause self-excited oscillations of the vortex rope in the draft tube at full load operating point. For the presented work, two-phase simulations are carried out at model scale on a domain ranging from the inlet of the spiral case to the outlet of the draft tube. At different locations, wall pressure measurements are available and compared to the simulation results. Furthermore, the dynamics of the cavity volume in the draft tube cone and at the trailing edge of the runner blades are investigated by comparing with high speed visualization. To account for the selfexcited behaviour, proper boundary conditions need to be set. In this work, the focus lies on the treatment of the boundary condition at the inlet. In the first step, the dynamic behaviour of the cavity regions is investigated using a constant mass flow. Thereafter, oscillations of the total pressure and mass flow rate are prescribed using various frequencies and amplitudes. This methodology enables to examine the response of the cavity dynamics due to different excitations. It can be observed that setting a constant mass flow boundary condition is not suitable to account for the self-excited behaviour. Prescribing the total pressure has the result that the frequency of the vapour volume oscillation is the same as the frequency of the excitation signal. Contrary to that, for an excitation with a mass flow boundary condition, the response of the system is not equal to the excitation.

    The essay is an empirical case study of famed British scientist Francis Crick. Viewing him as a 'cross-worlds influencer' who was moreover dedicated to a cause, I have tried to understand how these two characteristics influenced the trajectory of his long career and how they shaped his contributions to the diverse research fields in which he was active, and concluded that these characteristics reconfigure Crick's career into a coherent whole. First, I identify a major thread running through Crick's career: helping organise 'un-disciplined' new research fields, and show that his successive choices were not serendipitous but motivated by what he construed as a crusade against 'vitalism': anti-vitalism was a defining driver of his career. I then examine how Crick put his skills as a crossworlds influencer to the service of his cause, by helping organise his chosen fields of intervention. I argue that his activities as a cross-worlds influencer were an integral part of his way of 'doing science' and that his contributions to science, neuroscience in particular, should be re-evaluated in this light. This leads me to advance a possible strategy for historians to investigate big bioscience fields. Following Abir-Am, I propose to trace their genealogies back to the fluctuating semi-institutional gatherings and the institutional structures that sustained them. My research on Crick supports the view that such studies can bring insights into the question of why the contours of contemporary big bioscience endeavours have come to be shaped the way they are. Further, the essay provides a heuristic device for approaching these enquiries: 'follow the cross-worlds influencers' who worked to build and organise these semi-institutional gatherings and institutional structures.

    Soil organic matter (SOM) plays a key role in the cycling and retention of nitrogen and carbon within soil. Both above and belowground detrital inputs determine the nature and quantity of SOM. Studies on detrital impacts on SOM dynamics are underway at several LTER, ILTER and LTER-affiliated sites using a common experimental design, Detrital Input and Removal Treatments (DIRT). The concept for DIRT was originally based on experimental plots established at the University of Wisconsin Arboretum by Dr. Francis D. Hole in 1956 to study the effects of detrital inputs on pedogenesis. These plots are located on two forested sites and two prairie sites within the arboretum. Manipulations of the forested sites include double litter, no litter and removal of the O and A horizons. Manipulations of the prairie sites include harvest, mulch, bare and burn. These original treatments have largely been maintained since 1956. After 40 years of maintenance, there were significant differences in soil carbon between the double and no litter plots. The double litter plots had increased by nearly 30% while the no litter plots had decreased over 50%. The original DIRT plots are now 50 years old and have been re-sampled, where possible, for total carbon and nitrogen, labile and recalcitrant carbon fractions, net and gross nitrogen mineralization rates, and SOM bioavailability through CO2 respiration. The soils were fractionated by density to examine the role of carbon in each density fraction. The mean age of carbon in each fraction was determined by radiocarbon dating. This sampling and analysis is of special significance because it provides a glimpse into the future SOM trajectories for the new DIRT sites: Harvard Forest (MA), Bousson (PA), Andrews Experimental Forest (OR) and Sikfokut (Hungary).

    Full Text Available In the field of international scholarly journal publishing, manuscript editing has been established as an essential component of the publication process. As the necessity of this process has increased, the Korean Council of Science Editors has consistently provided education for training professional manuscript editors, and has worked to implement a manuscript editor certification system. Starting in 2014, the Korean Council of Science Editors thoroughly conducted background research and advanced analysis in preparation for such a system. Subsequently, a committee of experts was formed to develop and simulate an examination for this certification. This process culminated in the first manuscript editor certification examination, which was held in November 2016 and resulted in 40 initial Korea Manuscript Editors Certification holders. Examinations for the Korea Manuscript Editors Certification are scheduled to be held annually. The establishment of this certification system will contribute to strengthening individual capacities and further developing science journal publication in Korea by expanding the field of manuscript editing. Ultimately, this system will contribute to the promotion of Korean scientific journals to the level of prominent international journals.

  15. Quantifying the effect of editor-author relations on manuscript handling times.

    Science.gov (United States)

    Sarigöl, Emre; Garcia, David; Scholtes, Ingo; Schweitzer, Frank

    2017-01-01

    In this article we study to what extent the academic peer review process is influenced by social relations between the authors of a manuscript and the editor handling the manuscript. Taking the open access journal PlosOne as a case study, our analysis is based on a data set of more than 100,000 articles published between 2007 and 2015. Using available data on handling editor, submission and acceptance time of manuscripts, we study the question whether co-authorship relations between authors and the handling editor affect the manuscript handling time , i.e. the time taken between the submission and acceptance of a manuscript. Our analysis reveals (1) that editors handle papers co-authored by previous collaborators significantly more often than expected at random, and (2) that such prior co-author relations are significantly related to faster manuscript handling. Addressing the question whether these shorter manuscript handling times can be explained by the quality of publications, we study the number of citations and downloads which accepted papers eventually accumulate. Moreover, we consider the influence of additional (social) factors, such as the editor's experience, the topical similarity between authors and editors, as well as reciprocal citation relations between authors and editors. Our findings show that, even when correcting for other factors like time, experience, and performance, prior co-authorship relations have a large and significant influence on manuscript handling times, speeding up the editorial decision on average by 19 days.

    Full Text Available "The War-Prayer," written a hundred years ago as Mark Twain reflected on the conditions surrounding the U.S. decision to embark on the imperialist venture known as the Philippine-American War, speaks to us across time in strikingly uncanny ways. Although today "The War-Prayer" is increasingly accessible to readers worldwide, this important piece by Mark Twain has never received the critical attention that it warrants. Neither has it occupied the place that it deserves in the Mark Twain canon, or in the American literary canon. In the years since its first publication in 1923, it has often been reprinted. But it rarely appears in anthologies of American literature, and it is among the least well-known works by Twain as far as the general public is concerned. Indeed, educated individuals are often startled and shocked when they are introduced to this piece, dumbfounded as to why they never encountered it before. A question worth pondering: How might American history and world history in the 20th century have been different if "The War-Prayer" had been as familiar to every high school student as Tom Sawyer? As editors of this international forum on "The War-Prayer" in Mark Twain Studies, we are pleased to be able to give this important work by Mark Twain some of the attention that it has long deserved.

    The rapid growth of DNA sequencing throughput in recent years implies that graphical interfaces for viewing and correcting errors must now handle large numbers of reads, efficiently pinpoint regions of interest and automate as many tasks as possible. We have adapted consed to reflect this. To allow full-feature editing of large datasets while keeping memory requirements low, we developed a viewer, bamScape, that reads billion-read BAM files, identifies and displays problem areas for user review and launches the consed graphical editor on user-selected regions, allowing, in addition to longstanding consed capabilities such as assembly editing, a variety of new features including direct editing of the reference sequence, variant and error detection, display of annotation tracks and the ability to simultaneously process a group of reads. Many batch processing capabilities have been added. The consed package is free to academic, government and non-profit users, and licensed to others for a fee by the University of Washington. The current version (26.0) is available for linux, macosx and solaris systems or as C++ source code. It includes a user's manual (with exercises) and example datasets. http://www.phrap.org/consed/consed.html dgordon@uw.edu .

    The Structural Alignment Program STRAP is a comfortable comprehensive editor and analyzing tool for protein alignments. A wide range of functions related to protein sequences and protein structures are accessible with an intuitive graphical interface. Recent features include mapping of mutations and polymorphisms onto structures and production of high quality figures for publication. Here we address the general problem of multi-purpose program packages to keep up with the rapid development of bioinformatical methods and the demand for specific program functions. STRAP was remade implementing a novel design which aims at Keeping Interfaces in STRAP Simple (KISS). KISS renders STRAP extendable to bio-scientists as well as to bio-informaticians. Scientists with basic computer skills are capable of implementing statistical methods or embedding existing bioinformatical tools in STRAP themselves. For bio-informaticians STRAP may serve as an environment for rapid prototyping and testing of complex algorithms such as automatic alignment algorithms or phylogenetic methods. Further, STRAP can be applied as an interactive web applet to present data related to a particular protein family and as a teaching tool. JAVA-1.4 or higher. http://www.charite.de/bioinf/strap/

Being a 32-bit DOS application, it may be used as a default fast viewer/editor of time series in any compute shell ("commander") or in Windows. It allows to view the data in the "time" or "phase" mode, to remove ("obscure") or filter outstanding bad points; to make scale transformations and smoothing using few methods (e.g. mean with phase binning, determination of the statistically opti- mal number of phase bins; "running parabola" (Andronov, 1997, As. Ap. Suppl, 125, 207) fit and to make time series analysis using some methods, e.g. correlation, autocorrelation and histogram analysis: determination of extrema etc. Some features have been developed specially for variable star observers, e.g. the barycentric correction, the creation and fast analysis of "OC" diagrams etc. The manual for "hot keys" is presented. The computer code was compiled with a 32-bit Free Pascal (www.freepascal.org).

  20. Natural knowledge as a propaedeutic to self-betterment: Francis Bacon and the transformation of natural history.

    Science.gov (United States)

    Lancaster, James A T

    2012-01-01

    This paper establishes the 'emblematic' use of natural history as a propaedeutic to self-betterment in the Renaissance; in particular, in the natural histories of Gessner and Topsell, but also in the works of Erasmus and Rabelais. Subsequently, it investigates how Francis Bacon's conception of natural history is envisaged in relation to them. The paper contends that, where humanist natural historians understood the use of natural knowledge as a preliminary to individual improvement, Bacon conceived self-betterment foremost as a means to Christian charity, or social-betterment. It thus examines the transformation of the moralizing aspect of Renaissance natural history in Bacon's conception of his Great Instauration.

  1. Abortion, metaphysics and morality: a review of Francis Beckwith's defending life: a moral and legal case against abortion choice.

    Nobis, Nathan

    2011-06-01

    In Defending Life: A Moral and Legal Case Against Abortion Choice (2007) and an earlier article in this journal, "Defending Abortion Philosophically"(2006), Francis Beckwith argues that fetuses are, from conception, prima facie wrong to kill. His arguments are based on what he calls a "metaphysics of the human person" known as "The Substance View." I argue that Beckwith's metaphysics does not support his abortion ethic: Moral, not metaphysical, claims that are part of this Substance View are the foundation of the argument, and Beckwith inadequately defends these moral claims. Thus, Beckwith's arguments do not provide strong support for what he calls the "pro-life" view of abortion.

  2. Francis Bacon sob o olhar de Gilles Deleuze: a imagem como intensidade

    Directory of Open Access Journals (Sweden)

    Osvaldo Fontes Filho

    2007-12-01

    Full Text Available O ensaio de Gilles Deleuze La logique de la sensation é texto que se detém principalmente na prática e na eficácia da imagem. A pintura de Francis Bacon é ali tomada como paradigma de modernidade ao investir contra os clichês expressivos e ao produzir imagem junto à brutalidade dos fatos, como um contra-efeito do narrativo. Em uma obra que conjura todo modelo a representar, toda história a contar, “alguma coisa se passa”, explica Deleuze, “que define o funcionamento da pintura”. Algo se passa, tem lugar: o acontecimento de uma catástrofe e de uma histeria no ato de pintura que acomete a Figura de modo a transmitir uma potencial violência de reação e de expressão. O “Bacon” de Deleuze apresenta a realidade vivida em uma nova e não-convencional ordem de sensação. Neste artigo, são comentados os modos como o filósofo interpreta os atos físicos da pintura de Bacon — marcas aleatórias, varredura da massa pictural, escansão das superfícies —, procedimentos que introduzem no mundo visual da figuração a variedade caótica dos fatos e sentidos. Mostra-se como as faces e as figuras contorcidas, distorcidas, escorchadas de Bacon recebem uma voz conceitual complementar no texto de Deleuze.

    Francis turbines may produce spontaneous pulsations of pressure and output power when operating at very high discharge. In such cases there is a cavitating central vortex in the draft tube with variable cavity volume V{sub c}. Until today, researchers agree that the main destabilizing agent is the so-called mass flow gain factor, defined as the derivative of cavity volume by the local discharge. Recent studies about 1D high-load stability analysis assumed that the mass-flow gain factor obtained from steady-state vortex data acts on the transient discharge downstream of the cavity. There are however good reasons to question this assumption. Most strikingly, the direct cause of the mass flow gain effect is the increase of swirl produced at the runner exit and hence upstream, not downstream of the cavity. To enhance the reliability of full-load stability predictions, the authors directly investigated the vortex dynamics. The development of the transient cavitating flow in the draft tube was simulated by means of unsteady 2-phase CFD. CFD work started with 1-phase calculations as presented by other authors. This was then extended to a more realistic 2-phase calculation. To contain the computing time within acceptable limits, given the very fine mesh and short time step required, the simulation domain was restricted to the draft tube and, at the same time, the problem was reduced to a basically 2-dimensional rotationally symmetric case. The response of the cavitating draft tube flow to a time-dependent inflow and time-dependent pressure at the draft tube exit was simulated. The results were input to a statistical identification procedure to check possible 1D transient models and find representative parameter values in the sense of a best fit between 1D model and CFD result. As we had suspected, the conventional vortex model with mass flow gain controlled by downstream discharge is not compatible with direct simulation and needs to be modified. The CFD results correspond

  4. THE DESIRE FOR RECOGNITION IN THE CONTEXT OF FRANCIS FUKUYAMA’S UNIVERSAL HISTORY

    Full Text Available Introduction. Francis Fukuyama in his famous book “The End of History and the Last Man” assumes that human history should be considered as the battle of ideologies that reaches its goal in the universalization of Western liberal democracy. Author’s ideas have gained many supporters. At the same time, they were subjected to severe criticism that reflected the important trends of political life and ideological preferences. Leaving aside the criticism based on geopolitical and civilizational confrontation and confusion which confronts Fukuyama’s theory, it should be stated that anthropological aspect of Fukuyama’s theory has vastly evaded philosophical comprehension. Purpose. This article attempts to test Fukuyama’s theory through the lens of philosophical anthropology and analyze human desire for recognition in the context of Fukuyama’s World History. Methodology. The analysis is focused on human desire for recognition as a significant dimension of human nature. The author has used hermeneutical methodology and anthropological integrative approach. Theoretical basis and results. Fukuyama is not satisfied by merely economic interpretation of history emphasizing that human is not simply an economic animal. Economic development fails to explain why people advocate the principles of liberal democracy. The author goes back to Hegel’s non-materialistic view of history based on the struggle for recognition. According to Fukuyama, this deeply rooted human desire for recognition is the great motor of history and cause of tyranny, conflicts, and wars. But at the same time, it also acts as a psychological foundation of many virtues – the spirit of citizenship, courage, and justice. Throughout history, this desire for recognition was not satisfied. Only modern liberal democracy provides universal recognition of all humans ensuring and protecting their rights. Originality. Fukuyama’s concept is important and interesting because it draws

    In this work the incompressible turbulent flow in a high head Francis turbine under steady operating conditions is investigated using the open source CFD software package FOAM-extend- 3.1. By varying computational domains (cyclic model, full model), coupling methods between stationary and rotating frames (mixing-plane, frozen-rotor) and turbulence models (kω-SST, κε), numerical flow simulations are performed at the best efficiency point as well as at operating points in part load and high load. The discretization is adjusted according the y + -criterion with y + mean > 30. A grid independence study quantifies the discretization error and the corresponding computational costs for the appropriate simulations, reaching a GCI < 1% for the chosen grid. Specific quantities such as efficiency, head, runner shaft torque as well as static pressure and velocity components are computed and compared with experimental data and commercial code. Focusing on the computed results of integral quantities and static pressures, the highest level of accuracy is obtained using FOAM in combination with the full model discretization, the mixing-plane coupling method and the κω-SST turbulence model. The corresponding relative deviations regarding the efficiency reach values of Δη rel ∼ 7% at part load, Δη rel ∼ 0.5% at best efficiency point and Δη rel ∼ 5.6% at high load. The computed static pressures deviate from the measurements by a maximum of Δp rel = 9.3% at part load, Δp rel = 4.3% at best efficiency point and Δp rel = 6.7% at high load. Commercial code in turn yields slightly better predictions for the velocity components in the draft tube cone, reaching a good accordance with the measurements at part load. Although FOAM also shows an adequate correspondence to the experimental data at part load, local effects near the runner hub are captured less accurate at best efficiency point and high load. Nevertheless, FOAM is a reasonable alternative to commercial code

    The International Committee of Medical Journal Editors (ICMJE) provides recommendations to improve the editorial standards and scientific quality of biomedical journals. These recommendations range from uniform technical requirements to more complex and elusive editorial issues including ethical aspects of the scientific process. Recently, registration of clinical trials, conflicts of interest disclosure, and new criteria for authorship - emphasizing the importance of responsibility and accountability-, have been proposed. Last year, a new editorial initiative to foster sharing of clinical trial data was launched. This review discusses this novel initiative with the aim of increasing awareness among readers, investigators, authors and editors belonging to the Editors´ Network of the European Society of Cardiology. Resumo O Comitê Internacional de Editores de Revistas Médicas (ICMJE) fornece recomendações para aprimorar o padrão editorial e a qualidade científica das revistas biomédicas. Tais recomendações variam desde requisitos técnicos de uniformização até assuntos editoriais mais complexos e elusivos, como os aspectos éticos do processo científico. Recentemente, foram propostos registro de ensaios clínicos, divulgação de conflitos de interesse e novos critérios de autoria, enfatizando a importância da responsabilidade e da responsabilização. No último ano, lançou-se uma nova iniciativa editorial para fomentar o compartilhamento dos dados de ensaios clínicos. Esta revisão discute essa nova iniciativa visando a aumentar a conscientização de leitores, investigadores, autores e editores filiados à Rede de Editores da Sociedade Europeia de Cardiologia.

As Vera Mackie and Stephanie Hemelryk Donald (University of Sydney say in the introduction to the special issue: All of the contributors to this special issue have reflected on the stakes involved in negotiating differences in language and culture. In their research and professional practice they inhabit the ‘space between’: the space between languages, the space between cultures, and the space between academic disciplines. While many of our contributors are located in the Australian university system, we also have contributors from outside that system, as well as contributors who are theorising disparate sites for the negotiation of difference. The most exciting aspect of the papers presented here is the ability to move between the spheres of cultural theory and the everyday. Analytical techniques originally developed for literary and cultural analysis are brought to bear on the texts and practices of everyday life. In addition to the critical essays, three cultural works also intervene in the discussion over what it means to inhabit the ‘space between’ languages, cultures and countries. The guest editors and the PORTAL editorial committee would like to acknowledge and thank the following institutions and individual for the support that made this special issue possible: the Australian Research Council’s Cultural Research Network; the former Institute for International Studies at the University of Technology, Sydney; the School of Historical Studies at the University of Melbourne; and the ARC Cultural Literacies Node Convener, Mark Gibson.

    The Avogadro project has developed an advanced molecule editor and visualizer designed for cross-platform use in computational chemistry, molecular modeling, bioinformatics, materials science, and related areas. It offers flexible, high quality rendering, and a powerful plugin architecture. Typical uses include building molecular structures, formatting input files, and analyzing output of a wide variety of computational chemistry packages. By using the CML file format as its native document type, Avogadro seeks to enhance the semantic accessibility of chemical data types. The work presented here details the Avogadro library, which is a framework providing a code library and application programming interface (API) with three-dimensional visualization capabilities; and has direct applications to research and education in the fields of chemistry, physics, materials science, and biology. The Avogadro application provides a rich graphical interface using dynamically loaded plugins through the library itself. The application and library can each be extended by implementing a plugin module in C++ or Python to explore different visualization techniques, build/manipulate molecular structures, and interact with other programs. We describe some example extensions, one which uses a genetic algorithm to find stable crystal structures, and one which interfaces with the PackMol program to create packed, solvated structures for molecular dynamics simulations. The 1.0 release series of Avogadro is the main focus of the results discussed here. Avogadro offers a semantic chemical builder and platform for visualization and analysis. For users, it offers an easy-to-use builder, integrated support for downloading from common databases such as PubChem and the Protein Data Bank, extracting chemical data from a wide variety of formats, including computational chemistry output, and native, semantic support for the CML file format.

    Previous research suggests that when individuals encounter new information, they interpret it through perceptual 'filters' of prior beliefs, relevant social identities, and messenger credibility. In short, evaluations are not based solely on message accuracy, but also on the extent to which the message and messenger are amenable to the values of one's social groups. Here, we use the release of Pope Francis's 2015 encyclical as the context for a natural experiment to examine the role of prior values in climate change cognition. Based on our analysis of panel data collected before and after the encyclical's release, we find that political ideology moderated views of papal credibility on climate change for those participants who were aware of the encyclical. We also find that, in some contexts, non-Catholics who were aware of the encyclical granted Pope Francis additional credibility compared to the non-Catholics who were unaware of it, yet Catholics granted the Pope high credibility regardless of encyclical awareness. Importantly, papal credibility mediated the conditional relationships between encyclical awareness and acceptance of the Pope's messages on climate change. We conclude by discussing how our results provide insight into cognitive processing of new information about controversial issues. Copyright © 2017 Elsevier B.V. All rights reserved.

  12. Self-validated calculation of characteristics of a Francis turbine and the mechanism of the S-shape operational instability

    International Nuclear Information System (INIS)

    Zhang, Z; Titzschkau, M

    2012-01-01

    A calculation method has been presented to accurately estimate the characteristics of a Francis turbine. Both the shock loss at the impeller inlet and the swirling flow loss at the Impeller exit have been confirmed to dominantly influence the turbine characteristics and particularly the hydraulic efficiency. Both together totally govern the through flow of water through the impeller being at the rest. Calculations have been performed for the flow rate, the shaft torque and the hydraulic efficiency and compared with the available measurements on a model turbine. Excellent agreements have been achieved. Some other interesting properties of the turbine characteristics could also be derived from the calculations and verified by experiments. For this reason and because of not using any unreliable assumptions the calculation method has been confirmed to be self-validated. The operational instability in the upper range of the rotational speed, known as the S-shape instability, is ascribed to the total flow separation and stagnation at the impeller inlet. In that range of the rotational speed, the operation of the Francis turbine oscillates between pump and turbine mode.

    Full Text Available Predatory publishers are defined as publishers who have financial goals. This definition was introduced for the first time by Jeffrey Beall (2012. In some predatory publishers, we can find some papers that are not related to journal's aim and scope. These journals create special issues in order to publish papers that are not related to journal's aim and scope. Thus, we are faced with a question of how the editor of these journals could evaluate these papers. In some trusted journals, editor invites guest editors for special issues, which are related to journal's aim and scope. On the other hand predatory publishers, publish papers without any external reviewers or guest editors. In addition, some journals that publish irrelevant papers in regular issues are also found. This problem can be seen especially in some biological or life science journals. It seems that these problems pose new challenge for the academic world.

    Objective To estimate financial payments from industry to US journal editors. Design Retrospective observational study. Setting 52 influential (high impact factor for their specialty) US medical journals from 26 specialties and US Open Payments database, 2014. Participants 713 editors at the associate level and above identified from each journal’s online masthead. Main outcome measures All general payments (eg, personal income) and research related payments from pharmaceutical and medical device manufacturers to eligible physicians in 2014. Percentages of editors receiving payments and the magnitude of such payments were compared across journals and by specialty. Journal websites were also reviewed to determine if conflict of interest policies for editors were readily accessible. Results Of 713 eligible editors, 361 (50.6%) received some (>$0) general payments in 2014, and 139 (19.5%) received research payments. The median general payment was $11 (£8; €9) (interquartile range $0-2923) and the median research payment was $0 ($0-0). The mean general payment was $28 136 (SD $415 045), and the mean research payment was $37 963 (SD $175 239). The highest median general payments were received by journal editors from endocrinology ($7207, $0-85 816), cardiology ($2664, $0-12 912), gastroenterology ($696, $0-20 002), rheumatology ($515, $0-14 280), and urology ($480, $90-669). For high impact general medicine journals, median payments were $0 ($0-14). A review of the 52 journal websites revealed that editor conflict of interest policies were readily accessible (ie, within five minutes) for 17/52 (32.7%) of journals. Conclusions Industry payments to journal editors are common and often large, particularly for certain subspecialties. Journals should consider the potential impact of such payments on public trust in published research. PMID:29074628

The group: 1) Developed a statement of principles on the standards of professionalism and responsibilities of editors (this statement will be posted on the Web site after electronic consultation with and comment by WAME editors); 2) Agreed to assess the extent to which these principles are reflected in practice and to explore barriers to their adoption, using data from a survey and focus groups; 3) Developed and outlined an on-line program for distance learning, targeted at new editors; 4) Planned for formal evaluation of the educational outreach program; and 5) Agreed to support regional initiatives to strengthen local editorial capacity. Underpinning all past and proposed future activities is the WAME Web site. The ambitious plans outlined above will require extensive development of the site, plans for which were made at the Bellagio meeting.

    2012-01-01

    As I begin my tenure as Editor-in-Chief of Journal of Physics: Condensed Matter (JPCM), I look upon this opportunity as both an honour and a real challenge. The journal is in great shape thanks to the work of my predecessors, Marshall Stoneham and David Ferry. The journal's solid reputation is based largely on the work these gentlemen have done over the past decade. The other main reason for the success of JPCM is the amazing staff in Bristol; keep up the good work, please. When discussing the journal with scientists from all corners of the globe, one thing is always mentioned—JPCM is a very reliable journal with well-written, high-quality papers, and a fast but rigorous peer-review process that provides fair, detailed and constructive referee reports for the benefit of authors. This is due almost entirely to our great authors and referees; we rely on them every day—thank you. As the new Editor-in-Chief I hope to continue to improve still further the journal's status in condensed matter science. As mentioned above, our reputation is excellent, but the reality is that we live in a world of bibliometrics and rankings. Over the past few years JPCM has been repositioned as a journal at the forefront of condensed matter physics, and the impact of the journal should increase further as a result of continued emphasis on commissioning in cutting-edge areas identified by the Editorial Board and the journal team. In addition to regular papers, JPCM has a number of other content streams that authors and readers can benefit from. Fast track communications (FTCs) offer exceptionally fast publication for work of the highest impact and urgency. By their select nature, FTCs benefit from personal treatment by the Editorial Board and the average receipt-to-first-decision time is just 11 days (the average receipt-to-publication time is just 45 days). Topical reviews in JPCM make the journal one of the most authoritative sources of review content for condensed matter physics

    Biomedical journals are the main route for disseminating the results of health-related research. Despite this, their editors operate largely without formal training or certification. To our knowledge, no body of literature systematically identifying core competencies for scientific editors of biomedical journals exists. Therefore, we aimed to conduct a scoping review to determine what is known on the competency requirements for scientific editors of biomedical journals. We searched the MEDLINE®, Cochrane Library, Embase®, CINAHL, PsycINFO, and ERIC databases (from inception to November 2014) and conducted a grey literature search for research and non-research articles with competency-related statements (i.e. competencies, knowledge, skills, behaviors, and tasks) pertaining to the role of scientific editors of peer-reviewed health-related journals. We also conducted an environmental scan, searched the results of a previous environmental scan, and searched the websites of existing networks, major biomedical journal publishers, and organizations that offer resources for editors. A total of 225 full-text publications were included, 25 of which were research articles. We extracted a total of 1,566 statements possibly related to core competencies for scientific editors of biomedical journals from these publications. We then collated overlapping or duplicate statements which produced a list of 203 unique statements. Finally, we grouped these statements into seven emergent themes: (1) dealing with authors, (2) dealing with peer reviewers, (3) journal publishing, (4) journal promotion, (5) editing, (6) ethics and integrity, and (7) qualities and characteristics of editors. To our knowledge, this scoping review is the first attempt to systematically identify possible competencies of editors. Limitations are that (1) we may not have captured all aspects of a biomedical editor's work in our searches, (2) removing redundant and overlapping items may have led to the

    Full Text Available The second issue of PORTAL Journal of Multidisciplinary International Studies for 2007 is a special issue with the title Contesting Euro Visions, guest edited by Dimitris Eleftheriotis (University of Glasgow, Murray Pratt (University of Technology Sydney and Ilaria Vanni, (University of Technology Sydney. As the editors’ opening essay emphasises, this issue is not concerned to perpetuate myths of a Europe united or federated, or even cohered by shared values. Rather, it aims to reclaim something of the conceptual, transcultural and locational uncertainties encoded in the foundation myth of Europe’s origins: Europa’s seduction and abduction by Zeus, disguised as a white bull. As the editors argue, this myth is marked by the physical elusiveness of Europe’s actual location (Homer’s Europa being, for example, Phoenician, in what is now Syria, and also complicated by centuries of amendments and revisions. Thus, by approaching contemporary Europe through the prism of a mutating and unanchored foundational fiction, the editors argue that that fiction ‘can be used to understand how in Europe particular local histories and local knowledge intersect with global issues, and conversely how what appears to be “European” is, in fact, the result of global encounters. Narratives of European values need to be located in this striated space, while friction as an organising metaphor also explains the slippage and relation between the lived, heterogeneous embodiments of contemporary Europe and abstract notions of values.’ The other essays gathered in this special issue endorse this notion of a striated Europe, a shifting space best regarded as a space of friction. I would like to thank all of the authors included in this special issue for their patience, and their support for the Contesting Euro Visions ideal that frames the issue. I would also like to take the opportunity to announce a call for papers for the July 2008 issue of PORTAL

    Vainshtein. We had hoped that the Nobel Symposium should be a signal for improved relations between East and West, but in this respect we failed. The Symposium was held in the small town of Marstrand, a summer resort on an island outside Göteborg. The idea was to have it relatively close to home and to show the participants perhaps the best part of the local nature. Another motive was to keep the participants semi-isolated to provide ample time for discussions. With the somewhat heavy programme we found that even so, the days were not long enough. This Symposium was the second Nobel Symposium on elementary particle physics. The first one, also organized by our group, was held in 1968. We hope and believe that the next one need not be awaited another 18 years! The Symposium was made possible by a generous grant from the Nobel Foundation. An additional grant from the Royal Swedish Academy of Sciences was also essential. A grant from Nordita made it possible to invite some ten Nordic observers. We also gratefully acknowledge help with the organization of the Symposium from the city of Goteborg, the city of Kungälv, Volvo, Skandinaviska Enskilda banken, Ericsson AB and IBM Sweden. We thank all the participants for all their efforts, to come to our remote part of the world, to give excellent talks, to write up their talks astonishingly quickly and to share with us so much of their knowledge and expertise. Last but not least we are indebted to the members of the organizing committee, members of the group and the secretarial staff.

    In the analysis of fluid behavior through hydraulic turbines, two basic methodologies for flow analysis and optimization processes in turbines are used, which are: a) modeled of flow through the entire turbine (joint), or modeled one of each component separately, obtaining satisfactory results by both methodologies. The analysis of computational fluids dynamics (CFD) to geometries improved by means of finite volume method (FVM) with their corresponding initials and boundary conditions is made, to solve a system differential equations of second order that correspond to the flow around the dominion of runner blades; considering nonviscous flow and the implementation of the two equations models for the solution of the equations that govern the turbulent flow. Also, used parameterization techniques based in a parametric geometry an objective function and the diminution of cavitation. This work presents the optimization of a runner from a Francis hydro turbine for a 75 MW considering three different load conditions (75%, 85% and 100%) through CFD as a part of the hydraulic analysis for modernization of the actual condition of a power generation unit. Francis runner optimization is made, through a previous analysis of CFD by means of the FVM, considering the viscous effects of the fluid and the model of turbulence developed by Sparlart and Allmaras; modeling the wicket and runner separately. Later the generation of a parametric model of the runner is made and the simulation for the generation of data base is formed. Finally an objective function is considered to develop the optimal geometry of the runner blades. The results are presented in a graphic form in such a way, that it shows the distributions of pressure and speed around the blades runner, the geometrical and performance (efficiency and power) comparison between original and optimized model.

    Full Text Available [Reading “De uno” in light of Francis Bacon’s “Exemplum tractatus de iustitia universali, sive de fontibus iuris”]. Although Vico was admittedly disappointed by Bacon’s Exemplum tractatus, a parallel reading of this text and De uno can provide insights as to how Vico ended up having to confront a series of issues: how does the universal law project itself into history? Where does the law stem from? Is there a link between law, occasion, and utility? What are the sources and the scope of authority? How does violence affect the law? What role for religion and piety? How to devise a philology for the laws and ancient fables? Bacon’s scattered aphorisms offer glimpses into problems which find a solution in the all-encompassing order of De uno.

    We performed numerical simulation of flow in a laboratory model of a Francis hydroturbine at three regimes, using two eddy-viscosity- (EVM) and a Reynolds stress (RSM) RANS models (realizable k-ɛ, k-ω SST, LRR) and detached-eddy-simulations (DES), as well as large-eddy simulations (LES). Comparison of calculation results with the experimental data was carried out. Unlike the linear EVMs, the RSM, DES, and LES reproduced well the mean velocity components, and pressure pulsations in the diffusor draft tube. Despite relatively coarse meshes and insufficient resolution of the near-wall region, LES, DES also reproduced well the intrinsic flow unsteadiness and the dominant flow structures and the associated pressure pulsations in the draft tube.

  2. Using clinical supervision to improve the quality and safety of patient care: a response to Berwick and Francis.

    Science.gov (United States)

    Tomlinson, Jonathon

    2015-06-11

    After widely publicised investigations into excess patient deaths at Mid Staffordshire hospital the UK government commissioned reports from Robert Francis QC and Professor Don Berwick. Among their recommendations to improve the quality and safety of patient care were lifelong learning, professional support and 'just culture'. Clinical supervision is in an excellent position to support these activities but opportunities are in danger of being squeezed out by regulatory and managerial demands. Doctors who have completed their training are responsible for complex professional judgements for which narrative supervision is particularly helpful. With reference to the literature and my own practice I propose that all practicing clinicians should have regular clinical supervision. Clinical supervision has patient-safety and the quality of patient care as its primary purposes. After training is completed, doctors may practice for the rest of their career without any clinical supervision, the implication being that the difficulties dealt with in clinical supervision are no longer difficulties, or are better dealt with some other way. Clinical supervision is sufficiently flexible to be adapted to the needs of experienced clinicians as its forms can be varied, though its functions remain focused on patient safety, good quality clinical care and professional wellbeing. The evidence linking clinical supervision to the quality and safety of patient care reveals that supervision is most effective when its educational and supportive functions are separated from its managerial and evaluative functions. Among supervision's different forms, narrative-based-supervision is particularly useful as it has been developed for clinicians who have completed their training. It provides ways to explore the complexity of clinical judgements and encourages doctors to question one another's authority in a supportive culture. To be successful, supervision should also be professionally led and

  3. LDV survey of cavitation and resonance effect on the precessing vortex rope dynamics in the draft tube of Francis turbines

    The large-scale penetration of the electrical grid by intermittent renewable energy sources requires a continuous operating range extension of hydropower plants. This causes the formation of unfavourable flow patterns in the draft tube of turbines and pump-turbines. At partial load operation, a precessing cavitation vortex rope is formed at the Francis turbine runner outlet, acting as an excitation source for the hydraulic system. In case of resonance, the resulting high-amplitude pressure pulsations can put at risk the stability of the machine and of the electrical grid to which it is connected. It is therefore crucial to understand and accurately simulate the underlying physical mechanisms in such conditions. However, the exact impact of cavitation and hydro-acoustic resonance on the flow velocity fluctuations in the draft tube remains to be established. The flow discharge pulsations expected to occur in the draft tube in resonance conditions have for instance never been verified experimentally. In this study, two-component Laser Doppler Velocimetry is used to investigate the axial and tangential velocity fluctuations at the runner outlet of a reduced scale physical model of a Francis turbine. The investigation is performed for a discharge equal to 64 % of the nominal value and three different pressure levels in the draft tube, including resonance and cavitation-free conditions. Based on the convective pressure fluctuations induced by the vortex precession, the periodical velocity fluctuations over one typical precession period are recovered by phase averaging. The impact of cavitation and hydro-acoustic resonance on both axial and tangential velocity fluctuations in terms of amplitude and phase shift is highlighted for the first time. It is shown that the occurrence of resonance does not have significant effects on the draft tube velocity fields, suggesting that the synchronous axial velocity fluctuations are surprisingly negligible compared to the velocity

  4. FRamework Assessing Notorious Contributing Influences for Error (FRANCIE): Perspective on Taxonomy Development to Support Error Reporting and Analysis

    Energy Technology Data Exchange (ETDEWEB)

    Lon N. Haney; David I. Gertman

    2003-04-01

    Beginning in the 1980s a primary focus of human reliability analysis was estimation of human error probabilities. However, detailed qualitative modeling with comprehensive representation of contextual variables often was lacking. This was likely due to the lack of comprehensive error and performance shaping factor taxonomies, and the limited data available on observed error rates and their relationship to specific contextual variables. In the mid 90s Boeing, America West Airlines, NASA Ames Research Center and INEEL partnered in a NASA sponsored Advanced Concepts grant to: assess the state of the art in human error analysis, identify future needs for human error analysis, and develop an approach addressing these needs. Identified needs included the need for a method to identify and prioritize task and contextual characteristics affecting human reliability. Other needs identified included developing comprehensive taxonomies to support detailed qualitative modeling and to structure meaningful data collection efforts across domains. A result was the development of the FRamework Assessing Notorious Contributing Influences for Error (FRANCIE) with a taxonomy for airline maintenance tasks. The assignment of performance shaping factors to generic errors by experts proved to be valuable to qualitative modeling. Performance shaping factors and error types from such detailed approaches can be used to structure error reporting schemes. In a recent NASA Advanced Human Support Technology grant FRANCIE was refined, and two new taxonomies for use on space missions were developed. The development, sharing, and use of error taxonomies, and the refinement of approaches for increased fidelity of qualitative modeling is offered as a means to help direct useful data collection strategies.

  5. Space and time reconstruction of the precessing vortex core in Francis turbine draft tube by 2D-PIV

    2016-11-01

    Francis turbines operating at part load conditions experience the development of a high swirling flow at the runner outlet, giving rise to the development of a cavitation precessing vortex rope in the draft tube. The latter acts as an excitation source for the hydro-mechanical system and may jeopardize the system stability if resonance conditions are met. Although many aspects of the part load issue have been widely studied in the past, the accurate stability analysis of hydro-power plants remains challenging. A better understanding of the vortex rope dynamics in a wide range of operating conditions is an important step towards the prediction and the transposition of the pressure fluctuations from reduced to prototype scale. For this purpose, an investigation of the flow velocity fields at the outlet of a Francis turbine reduced scale physical model operating at part load conditions is performed by means of 2D-PIV in three different horizontal cross-sections of the draft tube cone. The measurements are performed in cavitation-free conditions for three values of discharge factor, comprised between 60% and 81% of the value at the Best Efficiency Point. The present article describes a detailed methodology to properly recover the evolution of the velocity fields during one precession cycle by means of phase averaging. The vortex circulation is computed and the vortex trajectory over one typical precession period is finally recovered for each operating point. It is notably shown that below a given value of the discharge factor, the vortex dynamics abruptly change and loose its periodicity and coherence.

    2007-09-01

    Scientific journals have a central place in protecting research integrity because published articles are the most visible documentation of research. We used SWOT analysis to audit (S)trengths and (W)eaknesses as internal and (O)pportunities and (T)hreats as external factors affecting journals' responsibility in addressing research integrity issues. Strengths include editorial independence, authority and expertise, power to formulate editorial policies, and responsibility for the integrity of published records. Weaknesses stem from having no mandate for legal action, reluctance to get involved, and lack of training. Opportunities for editors are new technologies for detecting misconduct, policies by editorial organization or national institutions, and greater transparency of published research. Editors face threats from the lack of legal regulation and culture of research integrity in academic communities, lack of support from stakeholders in scientific publishing, and different pressures.

    Directory of Open Access Journals (Sweden)

    Paul Allatson

    2006-09-01

    Full Text Available The second issue of PORTAL Journal of Multidisciplinary International Studies for 2006 features a special selection of essays grouped under the title ‘Women in Asia’ and guest-edited by Devleena Ghosh and Barbara Leigh, both from the University of Technology Sydney. The essays in this special issue had their first incarnations at the Eighth Women in Asia Conference, ‘Shadow Lines’, organised by the Women’s Caucus of the Asian Studies Association of Australia and the University of Technology Sydney (convened by Ghosh and Leigh, and held at the University of Technology Sydney from 26 to the 28 September 2005. Aiming self-consciously and tacitly to toy with, and dispute, the historical and discursive valencies accruing to the key, twined terms ‘women’ and ‘Asia’, the ten essays grouped here combine to form a rich repository of contemporary research about the status of women in many parts of that vast, arguably incoherent, geocultural space called Asia. All of the contributing authors thus ‘attempt to unsettle discourses about limits,’ to cite from co-editor Devleena Ghosh’s opening paper. That attempt is far from straightforward, as Ghosh elaborates: ‘That lines, borders and boundaries exist, whether of prejudice, politics, economics, or culture, is undeniable. But how do we analyse these issues without ossifying them, creating implacable alterities that refuse the liminal spaces that people occupy?’ Multivalent solutions are called for, Ghosh suggests, and these are to be found not simply in ‘counter-politics and interventions’, but also through the excavation and recognition of multiple subjectivities from/in ‘a thousand plateaus, [and] felt and experienced through the body, historical landscapes, domestic spaces, through performance as well as through the realm of the imaginary, in the impact of ideals and the weight of history’. In addition to the special section on ‘Women in Asia’, this edition of PORTAL

    Scientific communication, career advancement, and funding decisions are all dependent on research publications. The way manuscripts are handled by high-visibility, professionally edited magazines differs from the way academic journals evaluate manuscripts, using active scientists as monitoring editors. In this essay, I discuss the benefits that come with the involvement of active scientists. I enumerate the decisions a monitoring editor has to make, and how he or she goes about making them. Finally, I indicate ways in which authors can help to make the process a smoother and more positive experience.

    Objective  To estimate financial payments from industry to US journal editors. Design  Retrospective observational study. Setting  52 influential (high impact factor for their specialty) US medical journals from 26 specialties and US Open Payments database, 2014. Participants  713 editors at the associate level and above identified from each journal's online masthead. Main outcome measures  All general payments (eg, personal income) and research related payments from pharmaceutical and medical device manufacturers to eligible physicians in 2014. Percentages of editors receiving payments and the magnitude of such payments were compared across journals and by specialty. Journal websites were also reviewed to determine if conflict of interest policies for editors were readily accessible. Results  Of 713 eligible editors, 361 (50.6%) received some (>$0) general payments in 2014, and 139 (19.5%) received research payments. The median general payment was $11 (£8; €9) (interquartile range $0-2923) and the median research payment was $0 ($0-0). The mean general payment was $28 136 (SD $415 045), and the mean research payment was $37 963 (SD $175 239). The highest median general payments were received by journal editors from endocrinology ($7207, $0-85 816), cardiology ($2664, $0-12 912), gastroenterology ($696, $0-20 002), rheumatology ($515, $0-14 280), and urology ($480, $90-669). For high impact general medicine journals, median payments were $0 ($0-14). A review of the 52 journal websites revealed that editor conflict of interest policies were readily accessible (ie, within five minutes) for 17/52 (32.7%) of journals. Conclusions  Industry payments to journal editors are common and often large, particularly for certain subspecialties. Journals should consider the potential impact of such payments on public trust in published research. Published by the BMJ Publishing Group Limited.

  16. Survey Research in the Forest Science Journals - Insights from Journal Editors

    Directory of Open Access Journals (Sweden)

    2015-06-01

    Full Text Available Background and Purpose: Survey research is one of the most commonly applied approaches in the social sciences. In the forest research it has been used for more than five decades. In spite of that or the fact that the amount of survey-based articles in the forest science journals has increased during the last decade, their share in all articles published in 20 forest science journals (9,372 articles, 2005-2014 is quite modest (3.2%. In our paper we look at the opinions and attitudes of forest science journal editors towards survey research, as their perspective might enlarge our understanding of the use of this approach in the field of forestry. Materials and Methods: We selected 20 forest science journals - 15 from the SCI list and five non-SCI journals and contacted editors of these journals with the self-administered e-mail questionnaire. Data were collected in October 2014 and analyzed by descriptive statistics. The overall response rate was 75%. The assumptions for the study were based on the evidence addressing opinions and attitudes of journal editors from other research fields (finance since no similar study was found in the field of forestry. Results: The majority of editors reported the same review process for survey-based articles as for all others. In two journals, articles with the survey-based content are screened more rigorously and in two journals their publishing is generally discouraged. 40% of journal editors hold the view that no difference should be made between survey research and other types of original research, and another 40% think that survey research should in the first place play a complementary role. As the main strength of survey research editors see the possibility to obtain data unavailable from other sources. They perceive adverse selection and the difficulty to generalize results as the main weaknesses. Conclusions: Editors of forest science journals have similar opinion on survey research as those from the

    The purpose of this study, which falls within the purview of a nuclear physics research laboratory, is the development of a simple to use conversational text editor to mitigate the defects of the MMT2 monitor. The operations to be executed are: - creation of a source file written in FORTRAN - concatenation of the various stages to obtain a workable program: FORTRAN compilation, edition of links, group generation; - execution of this program. These operations are performed in two different ways: 1) by using the system controls as from the teleprinter (this corresponds to the previous use). The sequence of controls to be effected is described; 2) by using the EDI 125 conversational editor [fr

    I am honoured to take on the leadership of Plasma Sources Science and Technology (PSST) as the successor to Professor Mark J Kushner, with whom I have had the pleasure to work on the journal for many years. Under Mark's insightful and energetic leadership over the last six years, PSST has cemented its position as the journal of choice within its subject area and is now one of the most successful journals in the field. In this first issue of 2014, I would like to reflect on some of the events and achievements of 2013. At the start of the year the PSST Editorial Board, recognizing the vital importance of atomic, molecular and optical (AMO) data to low-temperature plasma physics, agreed that PSST would accept papers reporting such new data, generated through both experiment and theory. Jonathan Tennyson joined the Editorial Board to represent this area. In March Anne Bourdon joined the Associate Editor team and has since then played a key part in the journal's review process alongside our other Editors. During the autumn, PSST moved to a new editorial management system. In December Deborah O'Connell was awarded the 2013 Hershkowitz Early Career Award and Review and joins the Editorial Board as of 2014. I would also like to thank Miles Turner for his work in leading the drafting of a guide on the details necessary in the reporting of the results of computer simulations; the main conclusions of this report have been incorporated into the journal policy. Overall 2013 has been another successful year for PSST; paper submissions were up by 8% on the previous year and there was the highest ever number of downloads of PSST papers in one year. Another noteworthy feature of 2013 was the continuing improvement in publication times while maintaining our high standards for acceptance and providing expert feedback coupled with encouragement particularly to younger researchers and groups. Largely as a result of the hard work of our referees and Associate Editors, the average time

    relatively recent survey of 2002, it was found that about 60% of 192 authors of clinical practice guidelines reported they had financial connections with the companies whose drugs were under consideration. There is a strong case for making CPGs based not just on effectivity but cost effectivity. The various ramifications of this need to be spelt out. Work of bodies like the Appraisal of Guidelines Research and Evaluation (AGREE) Collaboration and Guidelines Advisory Committee (GAC) are also worth a close look.Even the actions of Foundations that work for disease amelioration have come under scrutiny. The process of setting up 'Best Practices' Guidelines for interactions between the pharmaceutical industry and clinicians has already begun and can have important consequences for patient care. Similarly, Good Publication Practice (GPP) for pharmaceutical companies have also been set up aimed at improving the behaviour of drug companies while reporting drug trialsThe rapidly increasing trend toward influence and control by industry has become a concern for many. It is of such importance that the Association of American Medical Colleges has issued two relatively new documents - one, in 2001, on how to deal with individual conflicts of interest; and the other, in 2002, on how to deal with institutional conflicts of interest in the conduct of clinical research. Academic Medical Centers (AMCs), as also medical education and research institutions at other places, have to adopt means that minimize their conflicts of interest.Both medical associations and research journal editors are getting concerned with individual and institutional conflicts of interest in the conduct of clinical research and documents are now available which address these issues. The 2001 ICMJE revision calls for full disclosure of the sponsor's role in research, as well as assurance that the investigators are independent of the sponsor, are fully accountable for the design and conduct of the trial, have

  10. Effective gene editing by high-fidelity base editor 2 in mouse zygotes

    Directory of Open Access Journals (Sweden)

    2017-06-01

    Full Text Available ABSTRACT Targeted point mutagenesis through homologous recombination has been widely used in genetic studies and holds considerable promise for repairing disease-causing mutations in patients. However, problems such as mosaicism and low mutagenesis efficiency continue to pose challenges to clinical application of such approaches. Recently, a base editor (BE system built on cytidine (C deaminase and CRISPR/Cas9 technology was developed as an alternative method for targeted point mutagenesis in plant, yeast, and human cells. Base editors convert C in the deamination window to thymidine (T efficiently, however, it remains unclear whether targeted base editing in mouse embryos is feasible. In this report, we generated a modified high-fidelity version of base editor 2 (HF2-BE2, and investigated its base editing efficacy in mouse embryos. We found that HF2-BE2 could convert C to T efficiently, with up to 100% biallelic mutation efficiency in mouse embryos. Unlike BE3, HF2-BE2 could convert C to T on both the target and non-target strand, expanding the editing scope of base editors. Surprisingly, we found HF2-BE2 could also deaminate C that was proximal to the gRNA-binding region. Taken together, our work demonstrates the feasibility of generating point mutations in mouse by base editing, and underscores the need to carefully optimize base editing systems in order to eliminate proximal-site deamination.

    Full Text Available Abstract Background So far, there have been no Flash-based web tools available for chemical structure input. The authors herein present a feasibility study, aiming at the development of a compact and easy-to-use 2D structure editor, using Adobe's Flash technology and its programming language, ActionScript. As a reference model application from the Java world, we selected the Java Molecular Editor (JME. In this feasibility study, we made an attempt to realize a subset of JME's functionality in the Flash Molecular Editor (FlaME utility. These basic capabilities are: structure input, editing and depiction of single molecules, data import and export in molfile format. Implementation The result of molecular diagram sketching in FlaME is accessible in V2000 molfile format. By integrating the molecular editor into a web page, its communication with the HTML elements on this page is established using the two JavaScript functions, getMol( and setMol(. In addition, structures can be copied to the system clipboard. Conclusion A first attempt was made to create a compact single-file application for 2D molecular structure input/editing on the web, based on Flash technology. With the application examples presented in this article, it could be demonstrated that the Flash methods are principally well-suited to provide the requisite communication between the Flash object (application and the HTML elements on a web page, using JavaScript functions.

    2017-09-01

    Full Text Available Abstract β-Thalassemia is a global health issue, caused by mutations in the HBB gene. Among these mutations, HBB −28 (A>G mutations is one of the three most common mutations in China and Southeast Asia patients with β-thalassemia. Correcting this mutation in human embryos may prevent the disease being passed onto future generations and cure anemia. Here we report the first study using base editor (BE system to correct disease mutant in human embryos. Firstly, we produced a 293T cell line with an exogenous HBB −28 (A>G mutant fragment for gRNAs and targeting efficiency evaluation. Then we collected primary skin fibroblast cells from a β-thalassemia patient with HBB −28 (A>G homozygous mutation. Data showed that base editor could precisely correct HBB −28 (A>G mutation in the patient’s primary cells. To model homozygous mutation disease embryos, we constructed nuclear transfer embryos by fusing the lymphocyte or skin fibroblast cells with enucleated in vitro matured (IVM oocytes. Notably, the gene correction efficiency was over 23.0% in these embryos by base editor. Although these embryos were still mosaic, the percentage of repaired blastomeres was over 20.0%. In addition, we found that base editor variants, with narrowed deamination window, could promote G-to-A conversion at HBB −28 site precisely in human embryos. Collectively, this study demonstrated the feasibility of curing genetic disease in human somatic cells and embryos by base editor system.

  4. Scientific value of systematic reviews: survey of editors of core clinical journals.

    Directory of Open Access Journals (Sweden)

    Joerg J Meerpohl

    Full Text Available BACKGROUND: Synthesizing research evidence using systematic and rigorous methods has become a key feature of evidence-based medicine and knowledge translation. Systematic reviews (SRs may or may not include a meta-analysis depending on the suitability of available data. They are often being criticised as 'secondary research' and denied the status of original research. Scientific journals play an important role in the publication process. How they appraise a given type of research influences the status of that research in the scientific community. We investigated the attitudes of editors of core clinical journals towards SRs and their value for publication. METHODS: We identified the 118 journals labelled as "core clinical journals" by the National Library of Medicine, USA in April 2009. The journals' editors were surveyed by email in 2009 and asked whether they considered SRs as original research projects; whether they published SRs; and for which section of the journal they would consider a SR manuscript. RESULTS: The editors of 65 journals (55% responded. Most respondents considered SRs to be original research (71% and almost all journals (93% published SRs. Several editors regarded the use of Cochrane methodology or a meta-analysis as quality criteria; for some respondents these criteria were premises for the consideration of SRs as original research. Journals placed SRs in various sections such as "Review" or "Feature article". Characterization of non-responding journals showed that about two thirds do publish systematic reviews. DISCUSSION: Currently, the editors of most core clinical journals consider SRs original research. Our findings are limited by a non-responder rate of 45%. Individual comments suggest that this is a grey area and attitudes differ widely. A debate about the definition of 'original research' in the context of SRs is warranted.

    Compassion is elemental in the care of a patient during their medical imaging (MI) procedure and is highly topical in the light of the Francis Report. The patient–practitioner interaction is an amalgam of context, communication and individual differences, and whilst compassion is a term in common parlance in the media, policy and radiographers' professional documents, its meaning and manifestation in radiography recruitment, education and practice are less clearly articulated. A review of the existing literature was undertaken, including a small scale study exploring patients' experiences in diagnostic medical imaging. Themes from the study included communication; competence; emotions; attitudes and relationships, but notably absent was any mention of compassion per se. Radiography research would benefit from further exploratory work into the nature of compassionate patient care in the unique context of the medical imaging encounter; offering an evidence-based contribution to radiography in the light of the Francis Report. - Highlights: • An increased focus on compassion was recommended in the Francis Report. • Best compassionate care is a requirement in radiographers' Code of Professional Conduct. • The meaning of compassionate patient care in radiography is not well understood. • Equally neither is the expression of compassion in radiography. • Research into compassion will contribute to evidence-based practice in radiography.

  7. La prolongation de la vie humaine selon Francis Bacon. Ou : quel Tithon voulons-nous être ?

    Full Text Available Afin de comprendre avec exactitude la manière dont Francis Bacon envisage la question de la prolongation de la vie humaine, il faut impérativement examiner l’assise théologique de la réflexion du philosophe à ce sujet. Il convient aussi de restituer l’intégration de cette réflexion dans les objectifs plus amples de la philosophie naturelle nouvelle. Enfin, il est nécessaire de comprendre les dimensions proprement morales de la question. Car la prolongation de la vie humaine n’est pas seulement, au sein de la philosophie naturelle nouvelle, un cas parmi d’autres des recherches qu’il faut désormais effectuer : en réalité, c’est elle qui lui donne et qui lui fixe son sens ; avec elle se joue l’effectivité de l’identité espérée entre science et puissance. Mais il faut encore préciser qu’il ne s’agit aucunement pour l’homme de vieillir pour vieillir : il s’agit pour lui de pouvoir vieillir bien. Les leçons que Bacon tire de la fable de Tithon sont ici véritablement décisives.

    Full Text Available In this paper, a new methodology is proposed to reduce the vortex-induced vibration (VIV and improve the performance of the stay vane in a 200-MW Francis turbine. The process can be divided into two parts. Firstly, a diagnosis method for stay vane vibration based on field experiments and a finite element method (FEM is presented. It is found that the resonance between the Kármán vortex and the stay vane is the main cause for the undesired vibration. Then, we focus on establishing an intelligent optimization model of the stay vane’s trailing edge profile. To this end, an approach combining factorial experiments, extreme learning machine (ELM and particle swarm optimization (PSO is implemented. Three kinds of improved profiles of the stay vane are proposed and compared. Finally, the profile with a Donaldson trailing edge is adopted as the best solution for the stay vane, and verifications such as computational fluid dynamics (CFD simulations, structural analysis and fatigue analysis are performed to validate the optimized geometry.

    The safety and stability of hydraulic turbine regulating system (HTRS) in hydropower plants become increasingly important since the rapid development and the broad application of hydro energy technology. In this paper, a novel mathematical model of Francis hydraulic turbine regulating system with a straight-tube surge tank based on a few state-space equations is introduced to study the dynamic behaviors of the HTRS system, where the existence of possible unstable oscillations of this model is studied extensively and presented in the forms of the bifurcation diagram, time waveform plot, phase trajectories, and power spectrum. To eliminate these undesirable behaviors, a specified fuzzy sliding mode controller is designed. In this hybrid controller, the sliding mode control law makes full use of the proposed model to guarantee the robust control in the presence of system uncertainties, while the fuzzy system is applied to approximate the proper gains of the switching control in sliding mode technique to reduce the chattering effect, and particle swarm optimization is developed to search the optimal gains of the controller. Numerical simulations are presented to verify the effectiveness of the designed controller, and the results show that the performances of the nonlinear HTRS system assisted with the proposed controller is much better than that with the commonly used optimal PID controller.

  10. Influence of upstream disturbance on the draft-tube flow of Francis turbine under part-load conditions

    Owing to the part-load operations for the enhancement of grid flexibility, the Francis turbine often suffers from severe low-frequency and large-amplitude hydraulic instability, which is mostly pertinent to the highly unsteady swirling vortex rope in the draft tube. The influence of disturbances in the upstream (e.g., large-scale vortex structures in the spiral casing) on the draft-tube vortex flow is not well understood yet. In the present paper, the influence of the upstream disturbances on the vortical flow in the draft tube is studied based on the vortex identification method and the analysis of several important parameters (e.g., the swirl number and the velocity profile). For a small guide vane opening (representing the part-load condition), the vortices triggered in the spiral casing propagate downstream and significantly affect the swirling vortex-rope precession in the draft tube, leading to the changes of the intensity and the processional frequency of the swirling vortex rope. When the guide vane opening approaches the optimum one (representing the full-load condition), the upstream disturbance becomes weaker and thus its influences on the downstream flow are very limited.

  11. Proper Orthogonal Decomposition of Pressure Fields in a Draft Tube Cone of the Francis (Tokke) Turbine Model

    The simulations of high head Francis turbine model (Tokke) are performed for three operating conditions - Part Load, Best Efficiency Point (BEP) and Full Load using software Ansys Fluent R15 and alternatively OpenFOAM 2.2.2. For both solvers the simulations employ Realizable k-e turbulence model. The unsteady pressure pulsations of pressure signal from two monitoring points situated in the draft tube cone and one behind the guide vanes are evaluated for all three operating conditions in order to compare frequencies and amplitudes with the experimental results. The computed velocity fields are compared with the experimental ones using LDA measurements in two locations situated in the draft tube cone. The proper orthogonal decomposition (POD) is applied on a longitudinal slice through the draft tube cone. The unsteady static pressure fields are decomposed and a spatio-temporal behavior of modes is correlated with amplitude-frequency results obtained from the pressure signal in monitoring points. The main application of POD is to describe which modes are related to an interaction between rotor (turbine runner) and stator (spiral casing and guide vanes) and cause dynamic flow behavior in the draft tube. The numerically computed efficiency is correlated with the experimental one in order to verify the simulation accuracy

  12. An Evaluation of a Phase-Lag Boundary Condition for Francis Hydroturbine Simulations Using a Pressure-Based Solver

    While the periodic boundary condition is useful for handling rotational symmetry in many axisymmetric geometries, its application fails for analysis of rotor-stator interaction (RSI) in multi-stage turbomachinery flow. The inadequacy arises from the underlying geometry where the blade counts per row differ, since the blade counts are crafted to deter the destructive harmonic forces of synchronous blade passing. Therefore, to achieve the computational advantage of modeling a single blade passage per row while preserving the integrity of the RSI, a phase-lag boundary condition is adapted to OpenFOAM® software's incompressible pressure-based solver. The phase-lag construct is accomplished through restating the implicit periodic boundary condition as a constant boundary condition that is updated at each time step with phase-shifted data from the coupled cells adjacent to the boundary. Its effectiveness is demonstrated using a typical Francis hydroturbine modeled as single- and double-passages with phase-lag boundary conditions. The evaluation of the phase-lag condition is based on the correspondence of the overall computational performance and the calculated flow parameters of the phase-lag simulations with those of a baseline full-wheel simulation.

  13. On the Flow Instabilities and Turbulent Kinetic Energy of Large-Scale Francis Hydroturbine Model at Low Flow Rate Conditions

    Full Text Available This paper is to make a better understanding of the flow instabilities and turbulent kinetic energy (TKE features in a large-scale Francis hydroturbine model. The flow instability with aspect of pressure oscillation and pressure-velocity correlation was investigated using large eddy simulation (LES method along with two-phase cavitation model. The numerical simulation procedures were validated by the existing experimental result, and further the TKE evolution was analyzed in a curvilinear coordinates. By monitoring the fluctuating pressure and velocities in the vanes’ wake region, the local pressure and velocity variations were proven to have a phase difference approaching π/2, with a reasonable cross-correlation coefficient. Also the simultaneous evolution of pressure fluctuations at the opposite locations possessed a clear phase difference of π, indicating the stresses variations on the runner induced by pressure oscillation were in an odd number of nodal diameter. Considering the TKE generation, the streamwise velocity component us′2 contributed the most to the TKE, and thus the normal stress production term and shear stress production term imparted more instability to the flow than other production terms.

    Cavitation on two symmetric foils, a NACA0015 hydrofoil and a scaled-down model of a Francis turbine guide vane (GV), was investigated by high-speed visualization and PIV. At small attack angles the differences between the profiles of the mean and fluctuating velocities for both hydrofoils were shown to be insignificant. However, at the higher angle of incidence, flow separation from the GV surface was discovered for quasi-steady regimes including cavitation-free and cavitation inception cases. The flow separation leads to the appearance of a second maximum in velocity fluctuations distributions downstream far from the GV surface. When the transition to unsteady regimes occurred, the velocity distributions became quite similar for both foils. Additionally, for the GV an unsteady regime characterized by asymmetric spanwise variations of the sheet cavity length along with alternating periodic detachments of clouds between the sidewalls of the test channel was for the first time visualized. This asymmetric behaviour is very likely to be governed by the cross instability that was recently described by Decaix and Goncalvès [8]. Moreover, it was concluded that the existence of the cross instability is independent on the test body shape and its aspect ratio.

    A bank of basis sets to be used in ab-initio calculations has been created. The bases are sets of contracted Gaussian type orbitals to be used as input to any molecular integral package. In this communication we shall describe the organization of the bank and a portable editor program which was designed for its maintenance and use. This program is operated by commands and it may be used to obtain any kind of information about the bases in the bank as well as to produce output to be directly used as input for different integral programs. The editor may also be used to format basis sets in the conventional way utilized in publications, as well as to generate a complete, or partial, manual of the contents of the bank if so desired.

    With the volume of manuscripts submitted for publication growing every year, the deficiencies of peer review (e.g. long review times) are becoming more apparent. Editorial strategies, sets of guidelines designed to speed up the process and reduce editors' workloads, are treated as trade secrets by publishing houses and are not shared publicly. To improve the effectiveness of their strategies, editors in small publishing groups are faced with undertaking an iterative trial-and-error approach. We show that Cartesian Genetic Programming, a nature-inspired evolutionary algorithm, can dramatically improve editorial strategies. The artificially evolved strategy reduced the duration of the peer review process by 30%, without increasing the pool of reviewers (in comparison to a typical human-developed strategy). Evolutionary computation has typically been used in technological processes or biological ecosystems. Our results demonstrate that genetic programs can improve real-world social systems that are usually much harder to understand and control than physical systems.

    We present the user interface and the software architecture of the Configuration Editor that is used by CMS physicists to configure their physics analysis tasks. Analysis workflows typically involve execution of a sequence of algorithms, and these are implemented as software modules that are integrated within the CMS software framework (CMSSW). In particular, a set of common analysis tools is provided in the so-called CMS Physics Analysis Toolkit (PAT) and these need to be steered and configured during the execution of an analysis job. The Python scripting language is used to define the job configuration that drives the analysis workflow. Configuring analysis jobs can be quite a challenging task, particularly for newcomers, and therefore a graphical tool, called the Configuration Editor, has been developed to facilitate the creation and inspection of these configuration files. Typically, a user-defined analysis workflow can be produced starting from a standard configuration file, applying and configuring PAT ...
