2013-01-01

In an editorial of a recent issue of a known academic journal, Prof. Hartmut Michel affirmed that “…the production of biofuels constitutes an extremely inefficient land use… We should not grow plants for biofuel production.”, after comparing the area occupied with plants for bioenergy production with the one required for photovoltaic cells to supply the same amount of energy for transportation. This assertion is not correct for all situations and this comparison deserves a more careful analysis, evaluating the actual and prospective technological scenarios and other relevant aspects, such as capacity requirements, energy consumed during the life cycle of energy systems and the associated impacts. In this communication this comparison is revaluated, presenting a different perspective, more favorable for the bioenergy routes. - Highlights: • Energy systems and life cycle impacts are compared under equal conditions. • The comparison is done between biofuels and photovoltaic/battery in mobility uses. • Biofuels are a valuable option when produced sustainably by efficient routes

"A milestone in modern research on the the harmony of the spheres." - Novalis magazine "This book reignites the debate on the harmony of the spheres." - Das Goetheanum Is the solar system ordered, or is it simply the result of random and chaotic accidents? This book takes us on a powerful and compelling journey of discovery, revealing the celestial spheres' astonishingly complex patterns. The movements of the planets are found to correspond accurately with simple geometric figures and musical intervals, pointing to an exciting new perspective on the ancient idea of a "harmony of the spheres". Hartmut Warm's detailed presentation incorporates the distances, velocities and periods of conjunction of the planets, as well as the rotations of the Sun, Moon and Venus. Numerous graphics - including colour plates - illustrate the extraordinary beauty of the geometrical forms that result when the movements of several planets are viewed in relation to one another. In addition, the author describes and analyses the conce...

Denis Guedj (right), pictured with Etiennette Auffray Hillemanns of the CMS collaboration and Hartmut Hillemanns of the DG-KTT group.French author Denis Guedj, who is also a mathematician and Professor of History of Science at Paris VIII University, visited CERN on 7 and 8 October. During a presentation in the CERN Library he discussed his 15 published books and likened the process of novel writing to working on a scientific experiment: it begins with a limited amount of data, and then questions arise, problems are solved and further research reveals truths. Denis Guedj works hard to ensure that his novels contain ‘true fiction’. His most recent visit to CERN will help him to write a new book set at the LHC in which he will combine his scientific interest in what happens when a proton and proton collide with a human story about what happens to a male and female physicist who meet in the LHC tunnel.

Full Text Available German Society for Sexual Research, Academy of Sexual Medicine and Society of Sexology formulated standards for evaluation and treatment of transsexuals. The creation of the standards involved Sophinette Becker, Hartmut A. G. Bosinski, Ulrich Clement, Wolf Eicher, Thomas M. Goerlich, Uwe Hartmann, Götz Kockott, Dieter Langer, Wilhelm E. Preuss, Gunter Schmidt, Alfred Springer, Reinhard Wille. Since 1980, the Federal Republic of Germany has a law on transsexualism, which regulates the right of the individual to change the sex. However, until now there were no specifically defined standards of assessment and treatment of transsexuals. For the first time, in 1979 Harry Benjamin invited the International Medical Association of Germany to revise the standards of medical care for gender dysphoria. The following standards of assessment and treatment of transsexuals have been developed at a conference convened by the German Society for Research Expert Committee under the leadership of Sophinette Becker. The review of currently valid standards for evaluation and treatment of transgender is the subject of this article

QUEM ESTÁ NO COMANDO? NEUROCIÊNCIA, RESSONÂNCIA E DESAFIOS PARA A TEOLOGIA

ABSTRACT: The relationship between body and soul or between body, soul and spirit is an ancient problem of anthropology, and also of Christian theology. In view of present day discoveries and new neuroscientific theories, the issue poses itself afresh. It practically migrated to the discussion of the relationship between brain and mind. Today, there is ample consensus that it is the brain that is in charge of the body. If we accept that, then who is in charge of the brain? Is it me, in the first person, my soul, my mind? Or is it “him”, in the third person, our own brain that determines me? And how about the second person – the human being in its relationship with God whom it calls “you”? Striving to overcome prejudices against a deterministic neuroscience, on the one hand, and a theology indifferent to science – and, indeed, such positions, wherever they are held – the present article seeks to deal with the human condition in its freedom, always precarious and restrained. Referring to neurobiological and psychiatric insights from Joachim Bauer, it argues for the importance of the relationship of the human being with the other, with God and with the world, in a form of resonance (Hartmut Rosa.

Spectrums Transform Operators in Bases of Fourier and Walsh Functions

Directory of Open Access Journals (Sweden)

V. V. Syuzev

2017-01-01

Full Text Available The problems of synthesis of the efficient algorithms for digital processing of discrete signals require transforming the signal spectra from one basis system into other. The rational solution to this problem is to construct the Fourier kernel, which is a spectrum of some basis functions, according to the system of functions of the other basis. However, Fourier kernel properties are not equally studied and described for all basis systems of practical importance. The article sets a task and presents an original way to solve the problem of mutual transformation of trigonometric Fourier spectrum into Walsh spectrum of different basis systems.The relevance of this theoretical and applied problem is stipulated, on the one hand, by the prevalence of trigonometric Fourier basis for harmonic representation of digital signals, and, on the other hand, by the fact that Walsh basis systems allow us to have efficient algorithms to simulate signals. The problem solution is achieved through building the Fourier kernel of a special structure that allows us to establish independent groups of Fourier and Walsh spectrum coefficients for further reducing the computational complexity of the transform algorithms.The article analyzes the properties of the system of trigonometric Fourier functions and shows its completeness. Considers the Walsh function basis systems in three versions, namely those of Hadamard, Paley, and Hartmut giving different ordering and analytical descriptions of the functions that make up the basis. Proves a completeness of these systems.Sequentially, for each of the three Walsh systems the analytical curves for the Fourier kernel components are obtained, and Fourier kernel themselves are built with binary rational number of samples of basis functions. The kernels are presented in matrix form and, as an example, recorded for a particular value of the discrete interval of N, equal to 8. The analysis spectral coefficients of the Fourier kernel

Huber, Robert

2008-11-25

Robert Huber and his colleagues, Johann Deisenhofer and Hartmut Michel, elucidated the three-dimensional structure of the Rhodopseudomonas viridis photosynthetic reaction center. This membrane protein complex is a basic component of photosynthesis - a process fundamental to life on Earth - and for their work, Huber and his colleagues received the 1988 Nobel Prize in Chemistry. Because structural information is central to understanding virtually any biological process, Huber likens their discovery to "switching on the light" for scientists trying to understand photosynthesis. Huber marvels at the growth of structural biology since the time he entered the field, when crystallographers worked with hand-made instruments and primitive computers, and only "a handful" of crystallographers would meet annually in the Bavarian Alps. In the "explosion" of structural biology since his early days of research, Huber looks to the rising generation of scientists to solve the remaining mysteries in the field - such as the mechanisms that underlie protein folding. A strong proponent of science mentorship, Huber delights in meeting young researchers at the annual Nobel Laureate Meetings in Lindau, Germany. He hopes that among these young scientists is an "Einstein of biology" who, he says with a twinkle in his eye, "doesn't know it yet." The interview was conducted by JoVE co-founder Klaus J. Korak at the Lindau Nobel Laureate Meeting 2008 in Lindau, Germany.

Full Text Available It is a pleasure to be involved in the preparation of the festschrifts honoring the 60th birthday of our good friend and colleague Professor Myroslav Holovko. Myroslav Holovko was born in 1943 in a small village of Chernijiv located in a beautiful area close to the Ukrainian Carpathians. After graduating in 1965 from the Ivano-Frankivsk Institute of Pedagogy he became a Ph.D. student at the Physics Department of the Lviv State University under the supervision of Professor Ihor Yukhnovskii. In 1969 Yukhnovskii became the head of Lviv Department of statistical theory of condensed states at the Institute for Theoretical Physics of the Ukrainian Academy of Sciences. From its early beginning the Lviv group experienced support and strong interest from another great Ukrainian - N.N.Bogolyubov, who was at that time Director of the Institute for Theoretical Physics. Yukhnovskii's group was a fantastic place for young people to grow up as scientists. At that time the group consisted of talented, ambitious and very enthusiastic young scientists selected among the best students who graduated mainly, but not exclusively, from Lviv University. It is interesting to note that Hartmut Krienke, who celebrated his 60th birthday last July was also a member of the Yukhnovskii's group, although Krienke came to Lviv from Rostock (Eastern Germany. Thanks to the outstanding personality of Prof. Yukhnovskii, a warm and friendly atmosphere in the group was combined with exceptionally high research standards.

Full Text Available Hartmut Meister,1 Linda Grugel,1 Markus Meis2 1Jean Uhrmacher Institute for Clinical ENT Research, University of Cologne, Cologne, Germany; 2Hoerzentrum Oldenburg, Oldenburg, Germany Objective: To determine the intention to use hearing aids (HAs by applying the theory of planned behavior (TPB. Design: The TPB is a widely used decision-making model based on three constructs hypothesized to influence the intention to perform a specific behavior; namely, “attitude toward the behavior”, “subjective norm”, and “behavioral control”. The survey was based on a TPB-specific questionnaire addressing factors relevant to HA provision. Study sample: Data from 204 individuals reporting hearing problems were analyzed. Different subgroups were established according to the stage of their hearing help-seeking. Results: The TPB models’ outcome depended on the subgroup. The intention of those participants who had recognized their hearing problems but had not yet consulted an ear, nose, and throat specialist was largely dominated by the “subjective norm” construct, whereas those who had already consulted an ear, nose, and throat specialist or had already tried out HAs were significantly influenced by all constructs. The intention of participants who already owned HAs was clearly less affected by the “subjective norm” construct but was largely dominated by their “attitude toward HAs”. Conclusion: The intention to use HAs can be modeled on the basis of the constructs “attitude toward the behavior”, “subjective norm”, and “behavioral control”. Individual contribution of the constructs to the model depends on the patient’s stage of hearing help-seeking. The results speak well for counseling strategies that explicitly consider the individual trajectory of hearing help-seeking. Keywords: hearing aid uptake, motivation, attitude, subjective norm, behavioral control

Full Text Available April Barbour1, Hartmut Derendorf21GlaxoSmithKline, King of Prussia, PA, USA; 2Department of Pharmaceutics, College of Pharmacy, University of Florida, Gainesville, FL, USAAbstract: Antimicrobial resistant bacteria are an increasing concern due to the resulting increase in morbidity, mortality, and health-care costs associated with the administration of inadequate or delayed antimicrobial therapy. The implications of inadequate antimicrobial therapy in complicated skin and skin structure infections (cSSSIs have gained more attention recently, most likely due to the recent emergence of community-acquired methicillin resistant Staphylococcus aureus (MRSA and the already high prevalence of MRSA in the nosocomial setting. Due to the continuous threat of resistance arising and the limitations of currently available agents for the treatment of cSSSIs, it is necessary to develop new antimicrobials for this indication. Ceftobiprole medocaril, the prodrug of ceftobiprole, is a parental investigational cephalosporin for the treatment of cSSSIs displaying a wide-spectrum of activity against both Gram-positive and Gram-negative species, including MRSA. Ceftobiprole displays noncomplex linear pharmacokinetics, is eliminated primarily by glomerular filtration, and distributes to extracellular fluid. Additionally, it has been shown that the extent of distribution to the site of action with regard to cSSSIs, ie, the extracellular space fluid of subcutaneous adipose tissue and skeletal muscle, is expected to be efficacious, as free concentrations meet efficacy targets for most pathogens. Similar to other beta-lactams, it displays an excellent safety and tolerability profile with the primary adverse events being dysgeusia in healthy volunteers, resulting from the conversion of the prodrug to the active, and nausea in patients. Ceftobiprole has demonstrated noninferiority in two large-scale pivotal studies comparing it to vancomycin, clinical cure rates 93.3% vs

A Review of Significant Advances in Neutron Imaging from Conception to the Present

Science.gov (United States)

Brenizer, J. S.

This review summarizes the history of neutron imaging with a focus on the significant events and technical advancements in neutron imaging methods, from the first radiograph to more recent imaging methods. A timeline is presented to illustrate the key accomplishments that advanced the neutron imaging technique. Only three years after the discovery of the neutron by English physicist James Chadwick in 1932, neutron imaging began with the work of Hartmut Kallmann and Ernst Kuhn in Berlin, Germany, from 1935-1944. Kallmann and Kuhn were awarded a joint US Patent issued in January 1940. Little progress was made until the mid-1950's when Thewlis utilized a neutron beam from the BEPO reactor at Harwell, marking the beginning of the application of neutron imaging to practical applications. As the film method was improved, imaging moved from a qualitative to a quantitative technique, with applications in industry and in nuclear fuels. Standards were developed to aid in the quantification of the neutron images and the facility's capabilities. The introduction of dynamic neutron imaging (initially called real-time neutron radiography and neutron television) in the late 1970's opened the door to new opportunities and new challenges. As the electronic imaging matured, the introduction of the CCD imaging devices and solid-state light intensifiers helped address some of these challenges. Development of improved imaging devices for the medical community has had a major impact on neutron imaging. Additionally, amorphous silicon sensors provided improvements in temporal resolution, while providing a reasonably large imaging area. The development of new neutron imaging sensors and the development of new neutron imaging techniques in the past decade has advanced the technique's ability to provide insight and understanding of problems that other non-destructive techniques could not provide. This rapid increase in capability and application would not have been possible without the

Full text: On May 12, Hans J. Specht, Scientific Director of the Geseilschaft fur Schwerionenforschung (GSI), welcomed an audience of more than 500 to celebrate the 25th anniversary of the Darmstadt heavy ion research Laboratory. Warm greetings and best wishes from Jürgen Ruttgers, Federal Minister for Education, Science, Research and Technology were presented by Hartmut Grubei, Chairman of the GSI Board. The Hessian Minister for Science and Art, Christine Hohmann-Dennhardt, pointed out that the promotion of various fields of research cannot be judged only by the expected return for everyday life. Joachim Treusch, the Chairman of the Association of National Research Centres, went further by stating that basic research, driven by curiosity and not aiming at short term applications, is a necessity. Darmstadt Mayor Peter Benz expressed his pride in having such a prestigious Laboratory in the city and looked forward to a new element named after it. CERN Director General Chris Llewellyn Smith underlined the growing importance of international and inter-regional scientific collaboration and paid tribute to the role of German physicists in general and GSI in particular in CERN's work. GSI is a major partner in the international lead ion programme at CERN which came into operation last year, a scientific and technological success which provides a useful role model for future international partnerships. After pointing to interesting parallels between the two Laboratories - both basing new projects on existing facilities, and both serving large user communities - he thanked GSI for its valuable contributions to CERN. Highlights from the 25 years of GSI were summarized in a talk by Dirk Schwalm, Managing Director of the Max Planck Institute for Nuclear Physics in Heidelberg. Among other points he presented the unique accelerator facility and the discovery of the five heaviest elements. He stated that many dreams from the founding period of GSI had become a reality, and

Oral contraceptives may provide a reasonable delivery vehicle for folate supplementation before conception in women of childbearing potential. This study aimed to demonstrate that a fixed-dose combination of an oral contraceptive and levomefolate calcium leads to sustainable improvements in folate status compared with an oral contraceptive + folic acid. Methods: This was a double-blind, randomized, parallel-group study in which 172 healthy women aged 18–40 years received ethinylestradiol (EE-drospirenone-levomefolate calcium or EE-drospirenone + folic acid for 24 weeks (invasion phase, and EE-drospirenone for an additional 20 weeks (folate elimination phase. The main objective of the invasion phase was to examine the area under the folate concentration time-curve for plasma and red blood cell (RBC folate, while the main objective of the elimination phase was to determine the duration of time for which RBC folate concentration remained ≥ 906 nmol/L after cessation of EE-drospirenone-levomefolate calcium. Results: Mean concentration-time curves for plasma folate, RBC folate, and homocysteine were comparable between treatment groups during both study phases. During the invasion phase, plasma and RBC folate concentrations increased and approached steady-state after about 8 weeks (plasma or 24 weeks (RBC. After cessation of treatment with levomefolate calcium, folate concentrations decreased slowly. The median time to RBC folate concentrations falling below 906 nmol/L was 10 weeks (95% confidence interval 8–12 weeks after cessation

(US DOE) gave a talk on 'Facing Our Energy Challenges in a New Era of Science' and William Phillips (Nobel laureate, NIST) presented a talk on 'Time, Einstein, and the Coolest Stuff in the Universe'. These public talks, held on Thursday and Friday evenings, respectively, were very accessible to a general audience. In addition, there were 61 progress reports on ongoing current research, and 26 special reports selected from the submitted abstracts based on their relevance and importance. These talks covered the full range of the conference topics. Notably, this was the 50th anniversary of ICPEAC and a formal session was held the first day to honor the event as well as those who were instrumental in initiating the conference. Thirteen scientists, representing both those from the early days of ICPEAC as well as chairs of previous ICPEACs, were present and called to the stage, including Benjamin Bederson, Lewis Branscomb, Robert Crompton, Alexander Dalgarno, Gordon Dunn, Werner Eissner, Brian Gilbody, Edward Gerjuoy, Hartmut Hotop, Eugen Merzbacher, Eugene Rudd, Felix Smith, and Aaron Temkin. Steven Manson was the chair of the session and he introduced those present from the early days. Joachim Burgdörfer presented an overview of the history of ICPEAC. This session was followed by a special anniversary reception to honor all of the early 'ICPEACers'. Generous support for the conference was provided by IUPAP, the WMU President's office, and the National Science Foundation. The funds were sizeable, timely, and greatly appreciated, and permitted us to support a significant number of young scientists (postdocs and students) and persons from developing/disadvantaged countries. Nevertheless, the number of requests was far greater than the total support available (by about a factor of five!), and we had to turn down many financial requests. We encourage the organizers of the next ICPEAC to seek a higher level of funding for supporting young scientists and scientists from

on various understandings of the phenomenon and highlights some conceptual problems and limitations of Digital Storytelling in educational contexts.The third paper in this edition addresses students and their use of information technologies in Russia. Alexander Porshnev, of National Research University, Nogorod, Russia and Hartmut Giest, of Potsdam University, Germany, authors of “University Students’ use of Information and Communication Technologies (ICT in Russia: A Focus on Learning and Everyday Life”” present results derived from a comparative analysis of German and Russian students.  They discuss the variance and diversity of ICT use in Russian Higher education and addresses contemporary problems in this context.The Norwegian nursing educators Edda Johansen, Thomas Harding (also Australian and Tone Marte Ljosaa introduce us to “Norwegian Nurses Experiences with Blended Learning: An evaluation study”. They are affiliated to the Buskerud University College and are concerned with developing fruitful and effective learning environments. In their study they focus what eventually gave nursing students confidence and a proper foundation for lifelong learning. The paper takes us on a journey to identify a best practice of blended learning.Finally, Heidi Phillipsen of the university of Southern Denmark, asks the question how it can be possible to make an entire short film in only 48 hours? The paper: “Scaffolded filmmaking in PlayOFF: A playground for worldwide film experiments” describes a particular method developed for producing films. It was initially a hallmark of modern Danish film production and has been refined and explicated by Heidi Philipsen, and then applied to the online film contest PlayOFF in Odense, a regional capital of Fyn, Southern Denmark. The paper addresses how scaffolding filmmaking affects creativity and how the experiences from two film contests may apply to an educational context.Barnett, Ronald (2000 Realizing the university in

award was Steven A. Sabbagh et al for the paper entitled 'Resistive wall stabilized operation in rotating high beta NSTX plasmas' (Nucl. Fusion 46 635-644). Reviews Last year I announced a revival of Nuclear Fusion Reviews, following a decision by the Board of Editors. 'A review of zonal flow experiments', by Akihide Fujisawa was the first fruit of this. In 2010, we are expecting to publish further review articles, the first of which is entitled 'Gyrokinetic simulations of turbulent transport' by Xavier Garbet, Yasuhiro Idomura, Laurent Villard and Tomo-Hiko Watanabe. Letters At the 2009 Board of Editors Meeting in Atlanta, the current letters procedure was summarized and it was noted that the peer review time for Letters is quite variable. Some are accepted within a month of submission, others take longer. Since the purpose of Letters is to provide a route for rapid communication, this is quite an important matter. It was agreed that the Board of Editors would play a more active role in the Letter approval process. If a reviewer asks for a second revision the Editor or a Board of Editors member will be queried as to whether the submission should still be treated as a Letter rather than a regular Paper. The Board of Editors The following Board of Editors members reached the end of their term in 2009: Amanda Hubbard, Yaroslav Kolesnichenko, Kunioki Mima, Boris Sharkov and Michael Ulrickson. On behalf of the Nuclear Fusion Office and the Chairman of the Board of Editors, Mitsuru Kikuchi, I would like to thank them for their efforts in support of the journal. At the same time, we welcomed: Hiroshi Azechi, Xuru Duan, Richard Hawryluk, Sergey Konovalov, Bruce Lipschultz, Peter Norreys, Francesco Romanelli, Tony Taylor and Hartmut Zohm. I am sure that such an illustrious group does not need any introduction to the readers of Nuclear Fusion and I am confident that the new members can only further the success of the journal. It is with great sadness that I have to note the

, Uhlmann et al and articles to be published in a later issue by Bäumchen and Jacobs, Walz et al). Moreover, simulations accounted for these new phenomena (see articles in this issue by Leonforte et al, Hyväaluoma et al, Varnik et al, Chelakkot et al, Litvinov et al and the article to be published in a later issue by Boettcher et al), since commercial software packages typically override these special yet fundamentally new conditions. For future applications, the know-how can be used, for instance, to manipulate particles or molecules in microfluidic systems (see articles in this issue by Nottebrock et al, Straube, Uhlmann et al and the article to be published in a later issue by Boettcher et al). The articles have been divided into four subsections: 'Probing the boundary condition', 'Flow over or in special geometries', 'Soft objects in fluid flow' and 'Manipulating flow'. Many articles, however, cover more than only one aspect and could easily be listed under one of the other subsections. Three articles, two listed in the section 'Probing the boundary condition' and one listed in 'Manipulating flow', could not be included and will be published in a later issue (Bäumchen and Jacobs, Walz et al, Boettcher et al). The collection of studies gives a comprehensive overview of what has been achieved to 'bridge the gap between molecular motion and continuum flow', which was the mission of the programme and which will now form a sound platform for continuative studies.
