    These Proceedings are dedicated to our co-editor Konrad Bajer, who carried the lion's share of the work involved until his sudden and untimely death from cancer on 29th August 2014. Konrad was one of the key Organisers of the program "Topological Dynamics in the Physical and Biological Sciences" held at the Isaac Newton Institute for Mathematical Sciences in Cambridge from July to December 2012. During that time, he was on leave from the University of Warsaw, and held a Visiting Fellow Commonership at Trinity College, Cambridge. He had particular responsibility for the satellite workshop Tangled Magnetic Fields in Astro- and Plasma Physics, held at ICMS, Edinburgh, in October 2012. Konrad graduated in Physics from the University of Warsaw in 1980, and took his PhD in Fluid Dynamics at DAMTP, Cambridge, 1984-89. He was active in EUROMECH, having been a principal organiser of the European Turbulence Conference (ETC13) in Warsaw 2011, and the meeting Turbulence: the Historical Perspective that followed it. He has been equally active in IUTAM; his distinction was recognised by his very recent election to the Congress Committee of IUTAM. Konrad's research interests were in magnetohydrodynamics and vortex dynamics in classical and quantum systems; also in problems of gasifcation, in which he played a coordinating role at the University of Warsaw. He impressed all with his exceptionally warm and friendly personality, and will be greatly missed in the whole scientifc community.

    Spectrum Roentgen Gamma (SRG) is an X-ray astrophysical observatory, developed by Russia in collaboration with Germany. The mission will be launched in 2016 into a 6-month-period halo orbit around L2. The mission lifetime is planned to be more than seven years. While the first four years of the mission are devoted to an all sky survey, the rest of the mssion will be used for pointed observations. The payload consists of two X-ray telescopes, eROSITA and ART-XC. The eROSITA sky survey will be about 30 times more sensitive than ROSAT at energies between 0.5 and 2 keV, while in the hard band (2-8 keV) it will provide the first ever true imaging survey of the sky. The design driving science is the detection of large samples of galaxy clusters out to redshifts z>1 in order to study the large scale structure in the universe and test cosmological models including Dark Energy. ART-XC's role is to extend the energy range of eROSITA alone, thereby doubling the effective area in the critical 4-7 keV range. The harder response of ART-XC also facilitates the x-ray detection of obscured AGN. Both instruments are currently in the flight model and calibration phase.

    The current status of roentgen videodensitometric techniques that provide an objective assessment of blood flow at selected sites within the coronary circulation were described. Roentgen videodensitometry employs conventional radiopaque indicators, radiological equipment and coronary angiographic techniques. Roentgen videodensitometry techniques developed in the laboratory during the past nine years, and for the past three years were applied to analysis of angiograms in the clinical cardiac catheterization laboratory.

    According to the German Atomic Energy Act the Federation is responsible for the construction and operation of installations for the safekeeping and disposal of radioactive waste. This duty was assigned to the Federal Office for Radiation Protection (Bundesamt fuer Strahlenschutz - BfS). In 1982, the Federal Institute of Physics and Metrology (Physikalisch Technische Bundesanstalt - PTB) as the precursor of BfS applied for a license for the disposal of radioactive waste with negligible heat generation in the Konrad iron ore mine near Salzgitter at the Ministry for Environment of Lower Saxony. After 25 years of plan approval procedure and subsequent lawsuits the license is now valid and Konrad is waiting for construction. Facing this challenge BfS has established a project team to supervise the in-house and external activities to be done. It is intended to construct the Konrad repository within a preparation period of two years and a subsequent erection phase of four years. Thus, Konrad is planned to come into operation in 2013. In this paper the development of the plan approval procedure, the technical design of the planned repository, especially with regard to safety-related aspects, and the planning for the construction will be discussed.

    2013-09-01

    Wilhelm Weinberg (1862-1937) is a largely forgotten pioneer of human and medical genetics. His name is linked with that of the English mathematician G. H. Hardy in the Hardy-Weinberg law, pervasive in textbooks on population genetics since it expresses stability over generations of zygote frequencies AA, Aa, aa under random mating. One of Weinberg's signal contributions, in an article whose centenary we celebrate, was to verify that Mendel's segregation law still held in the setting of human heredity, contrary to the then-prevailing view of William Bateson (1861-1926), the leading Mendelian geneticist of the time. Specifically, Weinberg verified that the proportion of recessive offspring genotypes aa in human parental crossings Aa × Aa (that is, the segregation ratio for such a setting) was indeed p=1/4. We focus in a nontechnical way on his procedure, called the simple sib method, and on the heated controversy with Felix Bernstein (1878-1956) in the 1920s and 1930s over work stimulated by Weinberg's article.

Mechanical models of the front end assembly, central electronics assembly, and detector assembly were used to accurately represent the HRI envelope for both fit checks and focal plane configuration studies. The mechanical and electrical interfaces were defined and the requirements for electrical ground support equipment were established. A summary description of the ROSAT telescope and mission is included.

  17. The Construction of the Konrad Repository - Status and Perspective - 13034

    2013-07-01

    Due to the Atomic Energy Act of Germany the Federation is responsible for the construction and operation of installations for the safekeeping and disposal of radioactive waste. The Federal Office for Radiation Protection (Bundesamt fuer Strahlenschutz - BfS) is assigned with this duty. In 1982 the abandoned iron ore mine Konrad near Salzgitter (Federal State of Lower Saxony) was proposed as a repository for low and intermediate level radioactive waste with negligible heat generation. After 20 years of plan approval procedure the license was granted by the Ministry for Environment of Lower Saxony in May 2002. This decision was finally confirmed by the Federal Administrative Court in March 2007. The construction has started, but former assumptions about the beginning of waste emplacement tuned out to be too optimistic. In the course of the preparatory work and the implementation planning it turned out that many changes need to be done. As a matter of fact most of the documents and planning originate from the 1990's and need to be revised because from that time on until now no adaptation was appropriate. The necessity to apply the state-of-the-art technology and other legal implications give rise to further changes and new licensing procedures, especially building licenses. Furthermore, the license from 2002 also includes a lot of collateral clauses that need to be fulfilled before radioactive waste can be emplaced. With this in mind, the time frame for the construction of the Konrad repository was revised in 2010. As a result, the completion of the erection before 2019 does not seem to be realistic. (authors)

    Grossman, W I

    1976-11-01

    One of the more curious by-products of the political and social unrest of the late 1960s, has been the emergence of and survival of interest in the writings of Wilhelm Reich (1897-1957). In the last few years, new translations of his books have appeared and some of his early work has been translated for the first time. A biography, magazine articles, and various surveys of his work convey the impression that his ideas are timely, or at least that they are historically important. However, I believe that the current enthusiasm for Reich owes more to the problems that interested him than to the light he shed on them. His great appeal for radical youth is based on his advocacy of social and sexual reform, for which he provided ideological support through a Marxist-psychoanalytic synthesis. By the technique of anthropological, economic, and psychological analysis, Reich tried to provide a scientific justification for revolutionary hopes. PMID:792926

  20. Utopianism in psychology: the case of Wilhelm Reich.

    Pietikainen, Petteri

    2002-01-01

    This article examines utopian elements in Wilhelm Reich's writings in his American phase (1939-1957) in order to illustrate utopian sources of dynamic psychology. Although there are scholars who have used the term "psychological utopia" and applied it to individual thinkers (Reich, Marcuse, Fromm) and to specific psychological disciplines (psychoanalysis, behaviorism, cognitive psychology), the term itself has remained elusive and vague. Furthermore, there have been few attempts to systematically examine utopian elements in twentieth-century psychology in general and the basic assumptions of psychological utopianism in particular. While pointing out that Reich's orgonomic theories have no scientific merit, this article argues for the relevancy of his ideas for understanding the nature of utopianism in dynamic psychology.

  6. Micromotion in knee arthroplasty. A roentgen stereophotogrammetric analysis of tibial component fixation.

    PubMed

    Ryd, L

    1986-01-01

    The modern era of endoprosthetic joint replacement started with the introduction of acrylic cement to improve component fixation. Long-term results have, however, indicated that prosthetic fixation remains critical; loosening at the bone-cement interface has become an important problem. Research in recent years has focused on attempts to achieve better fixation by improving cementing techniques, improving prosthetic design by, for example, adding metal support of polyethylene components and by exploring alternative ways to bond prosthetic components to bone without cement. The mechanical integrity of the bone-cement interface has been studied under laboratory conditions. Because of the in-vivo reaction of bone, with the interposition of a fibrous tissue layer at the interface, such studies are not totally valid. Studies on autopsy material, more closely resembling the in-vivo situation, are few and there has been only one previous study like the present one. In this study, roentgen stereophotogrammetric analysis (RSA) was evaluated and found to have an accuracy ten times better than conventional radiography. This accuracy was judged adequate for studies of micromotion. In this work, two types of micromotion of the tibial component were studied; migration, i.e. gradual motion over time, and inducible displacement, i.e. instant motion in response to external forces. Ninety-six knee arthroplasties for gonarthrosis, representing four different types of fixation were studied by roentgen stereophotogrammetric analysis (RSA). Eighty-nine arthroplasties were clinically successful. The follow-up ranged from two to five years. Full post-operative weight-bearing was allowed for all patients, except those operated with a Freeman-Samuelson prosthesis, who were adviced to use crutches for six weeks and partial weight-bearing for another six weeks. Fifty-one conventionally cemented all-polyethylene prostheses, 27 total and 24 unicompartmental, represented a baseline series. Migration was found for all prostheses, with a mean maximum deflection of 1.2 and 0.9 mm, respectively, after four years. In both groups, the major part of the migration occurred during the first year, after which the majority of the components did not migrate further. Some prostheses, with larger migration during the first year, continued to migrate throughout the investigation. None of the total, but the majority of the unicompartmental prostheses showed signs of cold flow within the polyethylene. All prostheses showed reversible inducible displacement, the maximum deflection ranging from 0.2 to 1.0 mm.(ABSTRACT TRUNCATED AT 400 WORDS) PMID:3461667

    1995-01-01

    Migration of 65 Charnley stems implanted with modern cementing techniques was studied by roentgen stereophotogrammetry. There were 25 patients with rheumatoid arthritis (RA) and 40 with osteoarthritis (OA) followed up for two years. In 43 cases a bone sample for histomorphometric analysis was obtained from the femur during the operation. In 22 cases the mean subsidence of the prosthetic head was 0.40 mm and in 20 the mean posterior migration was 1.25 mm. There was no difference in migration between the two diagnostic groups (p = 0.8) after adjusting for variations in gender, age and weight. Male gender was associated with increased subsidence (p = 0.006). Histological examination showed that the RA series had more osteoid surface (p = 0.04), but neither this, nor any of the other histomorphometric variables, influenced migration. These results suggest that, unlike the acetabular socket, the cemented Charnley femoral component is equally secure in osteoarthritis and in rheumatoid arthritis, and that its initial fixation is not influenced by the quality of the local cancellous bone. Our results provide data with which the early performance of new prosthetic designs and fixation methods can be compared. PMID:7822389

    1995-01-01

    In early January 1896 Wilhelm Conrad Röntgen sent offprints to several colleagues of his to make them acquainted with his discovery of the X-rays. From January 5, 1896 newspapers started reporting on that discovery worldwide from Vienna. In several cities the news immediately set off corresponding scientific activities among specialists. This paper looks into such activities carried out in Berlin to show how promptly Röntgen's discovery was taken up, with a number of priorities having been set in the capital of the German Reich. The X-ray photographs which Röntgen had forwarded together with his offprints were displayed and discussed at a meeting of the Berlin Physical Society as early as on January 4, 1896, making his discovery known to the public for the first time. On January 6, 1896 the discovery and photographs were presented at a session of the Berlin Association of Internal Medicine and its diagnostic application was discussed in the medical community for the first time. A few days after that, the first photographs shot by other authors after Röntgen, and their diagnostic use, were demonstrated in Berlin. Finally, Röntgen's early visit to Emperor William II on January 12, 1896, which led to the speedy introduction of the X-day technique into German military medicine, is discussed in detail.

    The case of a 31-year-old male is reported who had recurrent, unexplained abdominal complaints. After hospitalization, an ileus was localized by plain abdominal film in the ileocecal region. A contrast meal revealed a typical intraluminal (duodenal) diverticulum with an enlarged prestenotic duodenum that was undetected during endoscopy. At operation, the cause of the ileus was revealed to be a phytobezoar near the ileocolic valve. After removal and after transluminal resection of the diverticulum, the postoperative course was uneventful. The authors discuss the importance of early roentgen cinematography to clear up the pathogenesis of this very rare intraluminal lesion. PMID:7761597

    In 1964-1974, the German artist Max Ernst created, with the help of two friends, a series of works (books, movie, paintings) related to the astronomer Wilhelm Tempel. Mixing actual texts by Tempel and artistic features, this series pays homage to the astronomer by recalling his life and discoveries. Moreover, the core of the project, the book Maximiliana or the Illegal Practice of Astronomy, actually depicts the way science works, making this artwork a most original tribute to a scientist.

    The Spectrum-Rontgen-Gamma (SRG) mission is a Russian-German X-ray astrophysical observatory that carries two co-aligned and complementary X-ray telescope systems. The primary instrument is the German-led extended ROentgen Survey with an Imaging Telescope Array (eROSITA), a 7-module X-ray telescope system that covers the energy range from 0.2-12 keV. The complementary instrument is the Russian-led Astronomical Roentgen Telescope -- X-ray Concentrator (ART-XC or ART), a 7-module X-ray telescope system that provides higher energy coverage, up to 30 keV (with limited sensitivity above 12 keV).

    Since the license for the Konrad repository was finally confirmed by legal decision in 2007, the Federal Institute for Radiation Protection (BfS) has been performing further planning and preparation work to prepare the repository for operation. Waste conditioning and packaging has been continued by different waste producers as the nuclear industry and federal research institutes on the basis of the official disposal requirements. The necessary prerequisites for this are approved containers as well as certified waste conditioning and packaging procedures. The Federal Institute for Materials Research and Testing (BAM) is responsible for container design testing and evaluation of quality assurance measures on behalf of BfS under consideration of the Konrad disposal requirements. Besides assessing the container handling stability (stacking tests, handling loads), design testing procedures are performed that include fire tests (800 deg. C, 1 hour) and drop tests from different heights and drop orientations. This paper presents the current state of BAM design testing experiences about relevant container types (box shaped, cylindrical) made of steel sheets, ductile cast iron or concrete. It explains usual testing and evaluation methods which range from experimental testing to analytical and numerical calculations. Another focus has been laid on already existing containers and packages. The question arises as to how they can be evaluated properly especially with respect to lack of completeness of safety assessment and fabrication documentation. At present BAM works on numerous applications for container design testing for the Konrad repository. Some licensing procedures were successfully finished in the past and BfS certified several container types like steel sheet, concrete until cast iron containers which are now available for waste packaging for final disposal. However, large quantities of radioactive wastes had been placed into interim storage using containers which are not already licensed for the Konrad repository. Safety assessment of these so-called 'old' containers is a big challenge for all parties because documentation sheets about container design testing and fabrication often contain gaps or have not yet been completed. Appropriate solution strategies are currently under development and discussion. Furthermore, BAM has successfully initiated and established an information forum, called 'ERFA QM Konrad Containers', which facilitates discussions on various issues of common interest with respect to Konrad container licensing procedures as well as the interpretation of disposal requirements under consideration of operational needs. Thus, it provides additional, valuable supports for container licensing procedures. (authors)

    The Marshall Space Flight Center (MSFC) is developing x-ray mirror modules for the ART-XC instrument on board the Spectrum-Roentgen Gamma Mission. Four of those modules are being fabricated under a Reimbursable Agreement between NASA and the Russian Space Research Institute (IKI.) An additional three flight modules and one spare for the ART-XC Instrument are produced under a Cooperative Agreement between NASA and IKI. The instrument will consist of seven co-aligned x-ray mirror modules with seven corresponding CdTe focal plane detectors. Each module consists of 28 nested thin Ni/Co shells giving an effective area of 65 cm2 at 8 keV, response out to 30 keV, and an angular resolution of 45 arcsec or better HPD. Delivery of the first four modules is scheduled for November 2013, while the remaining three modules will be delivered to IKI in January 2014. We present a status of the ART x-ray module development at MSFC.

    Wilhelm Waldeyer was anatomist, physiologist, and pathologist during the German Empire (the so-called Second Reich). His scientific career left many traces still noticeable today. Not only is he commemorated in "his" pharyngeal lymphoid ring and other eponyms, but he also coined an impressive range of successful medical terms, including "chromosome" and "neuron." Moreover, Waldeyer left truly physical traces by donating parts of his body to his own Institute of Anatomy in Berlin. His scientific production does, however, also include "pseudoscientific" works, notably his questionable research on African brains. PMID:17072873

    The case of the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics (KWIA), from its inception in Weimar Republic Germany to its apogee under the rule of the Third Reich, is an example of how politics and human heredity can function as mutually beneficial resources. Whether it was a result of the Nazi bureaucrats' desire to legitimize their racial policy through science, or the KWIA personnel's desire to secure more funding for their research, the symbiotic relationship that developed between human genetics and Nazi politics could help explain why many scientists in the Third Reich undertook research projects that wholly transgressed the boundaries of morally acceptable science.

The report that he wrote on this occasion provides an overview on the conditions of astronomical research in Italyjust after the unification of the country. Later Struve sent a French translation of his report to the Italian astronomer Giovan Battista Donati, who used it to promote the construction of the Arcetri Observatory in Florence, which was inaugurated in 1872. We present here a transcription of the French translation of Struve's report and the transcription of a letter written by him in support of Donati's project PMID:26495588

    Several different types of cranial kinesis are present within modern birds, enabling them to move (part of) the upper bill relative to the braincase. This movement of the upper bill results from movement of the quadrate and the pterygoid-palatine complex (PPC). The taxon Palaeognathae is characterised by a very distinct PPC and a special type of cranial kinesis (central kinesis) that is very different from that found in the Neognathae. This has led some authors to hypothesise that there is a functional relationship between the morphology of the PPC and the type of cranial kinesis. This hypothesis is tested here by analysing the movement pattern of both the upper bill and the PPC in birds with three different types of cranial kinesis: prokinesis, distal rhynchokinesis and central rhynchokinesis. Movement patterns were determined using a Roentgen stereophotogrammetry method, which made it possible to detect very small displacements (0.5 mm) of bony elements in three dimensions, while the jaw muscles and ligaments remained intact. We found that in all types of kinesis investigated the movements of the quadrate, jugal bars and PPC are similar. Movement of the quadrate is transferred to the upper beak by the jugal bar and the PPC, which moves almost exclusively forwards and backwards, thereby elevating or depressing the upper bill. The differences between the types of kinesis lie only in the position of the point of rotation. These findings indicate that there is no correlation between the specific morphology of the PPC and the type of cranial kinesis. Several other factors, including the external forces applied during food acquisition, may influence the morphology of the PPC. Differences in PPC morphology therefore appear to be the result of different functional demands acting on the system simultaneously but with different strengths, depending on the species.

    The paper sheds light on the extent of collaboration between the pre-World War II German Psychoanalytic Society (DPG) and the Nazi regime. This is shown by the story of the expulsion of Wilhelm Reich from membership in the DPG, at Freud's own bid. A leading German psychoanalyst, Carl Müller-Braunschweig, published the paper "Psychoanalysis and Weltanschauung" in the fanatically "national" (so-called "völkisch") Nazi propaganda organ Reichswart in 1993 following consultations with officials of the International Psychoanalytic Association (IPA) who endorsed these policies. This paper by Müller-Braunschweig was used both to prevent the possible outlawing of psychoanalysis by the Nazis and to deny official DPG support to Wilhelm Reich and the group of leftist-oriented IPA analysts who joined forces with him in opposing Nazi ideology. The paper concludes with examples from post-1945 historiography showing how the exclusion of Reich and the related DPG/IPA compromise and "appeasement" policy were either ignored or disclaimed.

  12. The holist tradition in twentieth century genetics. Wilhelm Johannsen's genotype concept

    PubMed Central

    Roll-Hansen, Nils

    2014-01-01

    The terms ‘genotype’, ‘phenotype’ and ‘gene’ originally had a different meaning from that in the Modern Synthesis. These terms were coined in the first decade of the twentieth century by the Danish plant physiologist Wilhelm Johannsen. His bean selection experiment and his theoretical analysis of the difference between genotype and phenotype were important inputs to the formation of genetics as a well-defined special discipline. This paper shows how Johannsen's holistic genotype theory provided a platform for criticism of narrowly genocentric versions of the chromosome theory of heredity that came to dominate genetics in the middle decades of the twentieth century. Johannsen came to recognize the epoch-making importance of the work done by the Drosophila group, but he continued to insist on the incompleteness of the chromosome theory. Genes of the kind that they mapped on the chromosomes could only give a partial explanation of biological heredity and evolution. PMID:24882823

    From August 12--27, 1998 X-ray K-edge measurements were made on drain lines in seven rooms in Wilhelm Hall, Ames Laboratory. The purpose of these measurements was to determine the extent of thorium (and other heavy metal) contamination inside these pipes. The K-edge method is a noninvasive inspection technique that can provide accurate quantification of heavy metal contamination interior to an object. Of the seven drain lines inspected, one was found to have no significant contamination, three showed significant thorium deposits, two showed mercury contamination, and one line was found to contain mercury, thorium and uranium. The K-edge measurements were found to be consistent with readings from hand-held survey meters, and provided much greater detail on the location and amount of heavy metal contamination.

    2010-01-01

    During the Third Reich, the biological institutes of the Kaiser Wilhelm Society (KWG, Kaiser-Wilhelm-Gesellschaft) underwent a substantial reorganization and modernization. This paper discusses the development of projects in the fields of biochemical genetics, virus research, radiation genetics, and plant genetics that were initiated in those years. These cases exemplify, on the one hand, the political conditions for biological research in the Nazi state. They highlight how leading scientists advanced their projects by building close ties with politicians and science-funding organizations and companies. On the other hand, the study examines how the contents of research were shaped by, and how they contributed to, the aims and needs of the political economy of the Nazi system. This paper therefore aims not only to highlight basic aspects of scientific development under Nazism, but also to provide general insights into the structure of the Third Reich and the dynamics of its war economy.

    An operator interactive video system for the measurement of roentgen angiographically outlined structures is described. Left ventricular volume and three-dimensional shapes are calculated from up to 200 pairs of diameters measured from ventriculograms at the rate of 60 pairs of biplane images per second. The accuracy and reproducibility of volumes calculated by the system were established by analysis of roentgenograms of inanimate objects of known volume and by comparison of left ventricular stroke volumes calculated by the system with the stroke volumes calculated by an indicator-dilution technique and an aortic root electromagnetic flowmeter. Computer-generated display of the large amounts of data obtained by the videometry system is described.

    The 395th Wilhelm and Else Heraeus Seminar: `Time-dependent phenomena in Quantum Mechanics' took place at the Heinrich Fabri Institute in Blaubeuren, Germany, 12-16 September 2007. The conference covered a wide range of topics connected with time-dependent phenomena in quantum mechanical systems. The 20 invited talks and 15 short talks with posters at the workshop covered the historical debate between Schrödinger, Dirac and Pauli about the role of time in Quantum Mechanics (the debate was carried out sometimes in footnotes) up to the almost direct observation of electron dynamics on the attosecond time-scale. Semiclassical methods, time-delay, monodromy, variational principles and quasi-resonances are just some of the themes which are discussed in more detail in the papers. Time-dependent methods also shed new light on energy-dependent systems, where the detour of studying the time-evolution of a quantum states allows one to solve previously intractable problems. Additional information is available at the conference webpage http://www.quantumdynamics.de The organizer would like to thank all speakers, contributors, session chairs and referees for their efforts in making the conference a success. We also gratefully acknowledge the generous financial support from the Wilhelm and Else Heraeus Foundation for the conference and the production of this special volume of Journal of Physics: Conference Series.

  20. Physiological optics, cognition and emotion: a novel look at the early work of Wilhelm Wundt.

    PubMed

    Wassmann, Claudia

    2009-04-01

    The German physiologist Wilhelm Wundt, who later founded experimental psychology, arguably developed the first modern scientific conception of emotion. In the first edition of Vorlesungen über die Menschen- und Thierseele (Lectures on human and animal psychology), which was published in 1863, Wundt tried to establish that emotions were essential parts of rational thought. In fact, he considered them unconscious steps of decision-making that were implied in all processes of conscious thought. His early work deserves attention not only because it is the attempt to conceptualize cognition and emotion strictly from a neural point of view but also because it represents the very foundation of the debate about the nature of emotion that revolved around William James' theory of emotion during the 1890s. However, this aspect of his work is little known because scholars who have analyzed Wundt's work focused on his late career. Furthermore, historical analysis interpreted Wundt's work within a philosophical framework, rather than placing it in the context of German medical and physiological research in which it belongs. In addition, Wundt's early works are hardly available to an English speaking audience because they were never translated. PMID:18948411

    1997-01-01

    Today, our understanding of and approach to the exogenous causes of cancer are dominated by epidemiological practices that came into widespread use after World War II. This paper examines the forces, considerations, and controversies that shaped postwar risk factor epidemiology in the United States. It is argued that, for all of the new capabilities it brought, this risk factor epidemiology has left us with less of a clinical eye for unrecognized cancer hazards, especially from limited and localized exposures in the work-place. The focus here is on Wilhelm Hueper, author of the first textbook on occupational cancer (1942). Hueper became the foremost spokesman for earlier identification practices centering on occupational exposures. The new epidemiological methods and associated institutions that arose in the 1940s and 1950s bore an unsettled relation to earlier claims and methods that some, Hueper among them, interpreted as a challenge. Hueper's critique of the new epidemiology identified some of its limitations and potentially debilitating consequences that remain with us today. Images p1825-a p1827-a p1829-a PMID:9366640

    PubMed

    2014-12-01

    Carl Wilhelm Scheele (1742-1786) has an important place in the history of the discovery of respiratory gases because he was undoubtedly the first person to prepare oxygen and describe some of its properties. Despite this, his contributions have often been overshadowed by those of Joseph Priestley and Antoine Lavoisier, who also played critical roles in preparing the gas and understanding its nature. Sadly, Scheele was slow to publish his discovery and therefore Priestley is rightly recognized as the first person to report the preparation of oxygen. This being said, the thinking of both Scheele and Priestley was dominated by the phlogiston theory, and it was left to Lavoisier to elucidate the true nature of oxygen. In addition to his work on oxygen, Scheele was enormously productive in other areas of chemistry. Arguably he discovered seven new elements and many other compounds. However, he kept a low profile during his life as a pharmacist, and he did not have strong links with contemporary prestigious institutions such as the Royal Society in England or the French Académie des Sciences. He was elected to the Royal Swedish Academy of Science but only attended one meeting. Partly as a result, he remains a somewhat nebulous figure despite the critical contribution he made to the history of respiratory gases and his extensive researches in other areas of chemistry. His death at the age of 43 may have been hastened by his habit of tasting the chemicals that he worked on. PMID:25281638

  3. From Wilhelm von Humboldt to Hitler-are prominent people more prone to have Parkinson's disease?

    PubMed

    2000-10-01

    We describe Parkinsonism in prominent people, where Wilhelm von Humboldt and Adolf Hitler provide just two spectacular, opposing examples. In both of them, there is little if any evidence that the disease did influence their life ambitions, methods of achieving them or cognitive function in general. Thus, Hitler's Parkinsonism should remain a 'footnote' to history, and historians should acknowledge that in his last years, his trembling, his curbed posture, his slow walking, mask-like face and low voice did not indicate remorse, fear or depression as a consequence of his crimes, but were mere expressions of his disease which, until the end, had no impact on his intellectual skills and methods. The apparently higher incidence of Parkinsonism in prominent people may be just due to their higher visibility, or a consequence of disease-related personality traits (e.g. ambition, perfectionism, rigidity) which may contribute to becoming, e.g., a prominent authoritarian person. Perhaps even some early behaviour pattern (such as repressed emotions or acting in public-which could even increase the risk of some infection) contributes to a greater vulnerability for developing Parkinsonism. Further studying other prominent cases might lead us to better understanding of risk factors and the expression of early Parkinsonism. PMID:10900395

    Weise, Wilfried; Dorschner, Johann; Schielicke, Reinhardt E.

    Wilhelm Winkler was born in 1842 in Eisenberg, Thuringia, as the son of a lawyer. After attending the trading high school in Gera, Winkler worked as a merchant in Eisenberg, following in the footsteps of his grandfather. In 1875 he gave up this trade and devoted his time entirely to astronomy. Advised by Carl Bruhns, director of the Leipzig University Observatory, he established an observatory on his estate in Gohlis near Leipzig. From 1878 Winkler regularly observed sunspots; other fields of his observational interests were comets, occultations of stars by the Moon, and Jupiter's satellites. In 1887 he went to Jena, where he contacted Ernst Abbe, who was the head of the Jena observatory, too. For some years, Winkler's instruments were used in the new observatory erected by Abbe, which replaced the old Ducal Observatory of the Goethe era. Winkler donated the precision pendulum clock and some other instruments to this observatory. He also offered his observational assistance whenever it was wanted. In 1893 Winkler built up his own observatory in Jena and published annual reports on his work in the Vierteljahrsschrift of the Astronomische Gesellschaft. His observational results mainly appeared in the journal Astronomische Nachrichten. In 1902 he was awarded an honorary doctor's degree by the Philosophical Faculty of Jena University. However, at that time his physical constitution began gradually to fade. He lost his left eye due to a sarcoma, and finally he died at the age of 68. In his will, he left 100 000 Mark in form of securities to Jena University (Winkler Foundation). The University Observatory got his 4.5 m dome, the transport of which from his residence to the final site was also paid for by him, several instruments, and a lot of books. In 1936 Winkler's dome was closed by the University. The observatory was transferred from the University to the Zeiss works in exchange for the observatory in the Jena Forst. Zeiss sponsored the reconstruction of the old dome and its equipment with a telescope and, thus, laid the base for the modern Urania Popular Observatory.

  7. Neuroscience in its context. Neuroscience and psychology in the work of Wilhelm Wundt.

    PubMed

    Ziche, P

    1999-01-01

    Wilhelm Wundt (1832-1920), the first to establish an Institute devoted exclusively to psychological research in Germany, started his career as a (neuro)physiologist. He gradually turned into a psychologist in the 1860's and 1870's, at a time when neuroscience had to deal with the problem of giving an adequate physiological interpretation of the data accumulated by neuroanatomy. Neither the functional interpretation of brain morphology, nor the options provided by the reflex model seemed acceptable to Wundt. In his Physiological Psychology, first published in 1874, Wundt adds another aspect to this discussion by showing that psychology may help, and indeed is required, to clarify some of the most controversial problems in brain research. He thus became a key figure in neuroscience's struggle to locate itself within the various research traditions. The following theses will be argued for: 1. Wundt's turn to psychology resulted from his view that the methodological basis of physiological brain research of the time was unsatisfactory. 2. Psychology, in its attempt to solve these problems, implied a new conception of an interaction between experimental and theoretical brain research. 3. Wundt tried to demonstrate the necessity of psychological considerations for experimental brain research. These points are discussed with reference to Wundt's treatment of the localization of functions in the brain. According to Wundt, psychology can show, by analyzing the complex structure of intellect and will, that mental phenomena can be realized in the brain only in the form of complex interations of the elements of the brain. The results of the psychological considerations imply that a strict localizations cannot be correct; but they are also turned against the conception of a complete functional equivalence of the various parts of the cortext. For Wundt, a reconstruction of brain processes cannot start with neurones, but only with patterns of a functional organization of brain activity. Wundt accordingly proposes a functional interpretation on the level of the physiology of nervous tissue as well as for the over-all organization of the brain. PMID:11640242

    Friedrich Wilhelm Tönnies' name is hardly found in the major histories of astronomy. This is not surprising since he died before the age of twenty-one. Nevertheless, and perhaps because he knew at heart that not much time was granted to him, he left an astonishingly prolific oeuvre which indicates his rich talents. His contemporaries also testify that this son af a wealthy textile merchant had a great talent. But it is idle to speculate whether he would have become a second Bessel, or just an inconspicuous high school teacher in some remote Prussian province. He experienced a decisive career advancement by the Berlin astronomer J.E. Bode, obtained his Ph.D. already at the age of nineteen, published, among other things, about the large solar eclipse of November 19, 1816, and corresponded with several professional astronomers, before he succumbed to a pulmonary disease.

  10. Wilhelm Reich's self-censorship after his arrest as an enemy alien: the chilling effect of an illegal imprisonment.

    After discussing Wilhelm Reich's place in psychoanalysis, the article explores his arrest as an 'enemy alien' in December 1941. Reich's emotional responses to his imprisonment (which was illegal and which lasted nearly a month) are explored. A number of scholars have suggested that many European radical psychoanalysts refrained from sharing their former political ideas once they emigrated to the United States. Following a brief discussion of this pattern of 'silencing,' it is argued that Reich's withholding certain documents from publication was due to a self-imposed censorship, motivated in part by the fear of further governmental interference with his life and work. This fear, however, did not extend to his discussion of his newly developed theory of orgone energy. PMID:24628260

    The objective of the present study was to evaluate, in a prospective, single-center study, the effectiveness of the Wilhelm-type stent used in interventional radiology for the management of epiphora. Patients (n = 104; mean age 64 [range 25-88]; 33 male and 71 female) with severe epiphora had the stents inserted (135 stents in 115 eyes) to treat obstruction of the nasolacrimal system. The etiology of the obstruction was idiopathic in 83 cases, chronic dacryocystitis in 31, cases and postsurgical status in 1 case. The overall technical success rate of stent placement was near 94%. Resolution of epiphora was complete in 105 cases and partial in 3 cases. During a mean 13-month follow-up (range 1 week to 28 months), the median duration of primary patency was 11 months, and the percentage of patency at 6 months was 60.8%, at 1 year was 39.6%, and at 2 years was 25%. Stents malfunctioned in 54 cases, and all were easily withdrawn except in 1 case. Of these 27 cases, patency recovered spontaneously in 9 and by way of a second stent in 18. Secondary patency was 50%. Factors presdisposing to lower primary patency are inflammatory etiology and location of the obstruction. The benefit of stent deployment is clear with respect to the resolution of epiphora in candidate patients for percutaneous treatment. Technical and/or design improvements would be welcomed.

    During the first half of the 19th century, idealistic morphology developed into an influential research program in the German biosciences. This program was based on the concept of an ideal connection existing between various living beings. The growth of Darwinian thought and its new paradigm of historical explanation supplanted the idealistic morphology. Yet in the first half of the 20th century the principles of idealistic morphology experienced a powerful revival. Wilhelm Troll (1897-1978) was one of the most significant figures in this renaissance. Guided by the ideas of J.W. von Goethe, Troll established a research program rejecting causal, functional, and phylogenetic explanations as well as the idea of evolutionary adaptation. Instead, he attempted to create a 'pure' morphology based on the descriptions of various plant species. Governed by some explicitly metaphysical presumptions, Troll based his theory on the description of the organismal Gestalt. In consequence, his theory was actually a return to the proper idealistic morphology as it was known in the early 19th century. It lead German botanical morphology to a period of methodological and epistemological return. PMID:16602487

This paper presents some of the important results given in the interim reports of this commission that are relevant to psychiatry. It focuses on brain research, anthropology, psychiatric genetics, and the role of the well-known biochemist Adolf Butenandt. In general, the interim reports reflect the numerous links between the biomedical research of the KWG and the institutions of the National Socialist (Nazi) state. However, they do not yet allow a final historical assessment as to the complex situation of this field of research during National Socialism. PMID:12430055

    This essay analyzes one of Germany's former premier research institutions for biomedical research, the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics (KWIA) as a test case for the way in which politics and human heredity served as resources for each other during the Third Reich. Examining the KWIA from this perspective brings us a step closer to answering the questions at the heart of most recent scholarship concerning the biomedical community under the swastika: (1) How do we explain why the vast majority of German human geneticists and eugenicists were willing to work for the National Socialist state and, at the very least, legitimized its exterminationist racial policy; and (2) what accounts for at least some of Germany's most renowned medically trained professionals' involvement in forms of morally compromised science that wholly transcend the bounds of normal scientific practice? Although a complete answer to this question must await an examination of other German biological research centers, the present study suggests that during the Nazi period the symbiotic relationship between human genetics and politics served to radicalize both. The dynamic between the science of human heredity and Nazi politics changed the research practice of some of the biomedical sciences housed at the KWIA. It also simultaneously made it easier for the Nazi state to carry out its barbaric racial program leading, finally, to the extermination of millions of so-called racial undesirables. PMID:17212034

    In the middle of the eighteenth century, Carl von Linné, Johann Christoph Gatterer, and Christian Wilhelm Büttner attempted to realize the old idea of deciphering the alphabet of the world, which Francis Bacon had raised as a general postulate of science. This article describes these attempts and their interrelations. Linné used the model of the alphabet to classify plants according to the characters of this fruiting body. Gatterer, one of the leading German historians during the Enlightenment, adopted the botanical method of classification by genus and species to classify the history of scripts. He used the forms of the alphabetic characters to measure the age of manuscripts and to map the process of history as a genealogy of culture. Gatterer collaborated closely with Büttner, the first Göttingen professor of natural history. Büttner constructed a general alphabet of languages which connected the phonetics of language with the historically known alphabets. Early on, diplomatics and ethnography combined the natural order of natural history and the cultural order of the alphabet with the attempt to register development and to document development by the evolution of forms. Based on the shared model of the alphabet and on the common necessity to classify their empirical material, natural history and the description of culture were related attempts in the middle of the eighteenth century to comprehend the alphabetically organized nature and a naturally ordered culture.

    The Leipzig anatomist and physiologist Ernst Heinrich Weber had introduced physiological thinking in anatomy and exact methods of mathematical physics to the study of the functioning of the body making him the founder of a physically orientated physiology. But he would not have been that excellent physiologist without being a nonetheless distinguished anatomist since he solved his physiological problems usually following function in close relation to structure. Together with his brother Wilhelm Eduard Weber (1804-1891), who later was to become a famous physicist, in their theory of waves he laid the basis for an exact analysis of the movements of fluids in elastic tubes und was the first to apply the basic laws of hydrodynamics to the circulation of the blood. In collaboration with his youngest brother Eduard Friedrich Wilhelm Weber (1806-1871), who worked as a prosector at his institute and together with Wilhelm Weber had studied the mechanics of the walking apparatus, he demonstrated the inhibiting effect of the vagus nerve on the action of the heart. Ernst Heinrich Weber's approach to consider an organ as a whole not neglecting the study of its function set him apart from most of his contemporaries and has characterized the work of the Leipzig anatomists and physiologists since his time. Among those was Wilhelm His from Basle who succeeded him in the chair of anatomy in 1872. On the basis of a systematic analysis of human embryos by means of serial sections and plastic reconstruction His completely reformed the field of embryology and was the first to present a comprehensive treatise on human embryology. The making of modern human embryology was, above all, his achievement. He did not confine himself to mere description but wanted to gain deeper insight into the causal events by developmental-mechanical conceptions. With his detection of the neuroblasts and that they give rise to an axon and later to dendrites His provided the developmental foundations for the neuron-theory. PMID:16320825

    Despite the fact that much has been written in recent years about the science of heredity under the Third Reich, there is as yet no satisfying analysis of two central questions: What, if anything, was peculiarly "Nazi" about human genetics under National Socialism? How, under whatever set of causes, did at least some of Germany's most well-known and leading biomedical practioners become engaged in entgrenzte Wissenschaft (science without moral boundaries)? This paper attempts to provide some answers to these two questions comparing three institutes that studied eugenics and human heredity in the 1920s and 1930s: the Eugenics Record Office at Cold Spring Harbor, New York, directed by Charles B. Davenport; the Kaiser Wilhelm Institute for Anthropology, Human Heredity and Eugenics, in Berlin, directed by Eugen Fischer; and the Maxim Gorky Medical Genetics Institute in Moscow, directed by Solomon G. Levit. The institutes are compared on the basis of the kind and quality of their research in eugenics and medical genetics, organizational structure, leadership, patronage (private or state), and the economic-social-political context in which they functioned.

    The Grand-ducal University Eye Department in Rostock was solemnly inaugurated 16 May 1892. According to many years of studies in Europe and on efforts to build this clinic, construction was outlined by Professor Carl Wilhelm v. Zehender, but the drafts were executed by the "Grossherzoglich-Mecklenburgisch-Schwerinschen Medicinalcommission" and Landbaumeister Schlosser in winter 1888/89. Professor v. Zehender, who originated from a very ancient Swiss family, was born in Bremen, 21 May 1819. He studied medicine in Goettingen, Jena, Prague, Paris and Vienna. During this time he developed a lifelong friendship with Albrecht v. Graefe. 1856 he took over the medical care for the hereditary duke Georg von Mecklenburg-Strelitz and published the "Correspondenzblatt für Aerzte im Grossherzoglichen Mecklenburg-Strelitz". 1857, during a conference in Heidelberg, his initiative led in the long run to the establishment of the "Heidelberger Ophthalmologische Gesellschaft", the forerunner of the "Deutsche Ophthalmologische Gesellschaft", which was founded in 1920. In 1863 the first edition of "Klinische Monatsblaetter für Augenheilkunde" was published as a periodical; the cover page bore its name as the founder of the magazine. In 1866, after the death of the hereditary duke and a professorship in his hometown Berne, he became honorary professor of the Rostock University, and from 1869 onwards he chaired the clinic as a regular professor. After all his efforts to build his own hospital had failed, he demonstratively and finally resigned from his professorship in 1889. He went to Munich and became editor of the " Klinische Monatsblaetter für Augenheilkunde". In 1907 he moved with his wife via Eutin to Warnemuende. There the nestor of world ophthalmologists died at the age of 98. His burial place without gravestone is situated in today's landscape park "Stephan Jantzen". So far all efforts of the author and of the Rostock University Eye Department taken after 1980 to create a worthy note to this exceptional ophthalmologist in the Baltic Sea resort Warnemuende were unsuccessful, also for financial reasons. But on 2.9.2002 with the help of the Lighthouse Club of Warnemuende a memorial plaque to Prof. C. W. v. Zehender was mounted on the guest house "Margarete". This plaque commemorates Professor Zehender's merits in establishing the DOG, planning and building the eye clinic of the university of Rostock. PMID:12612842

    W.C. Röntgen reported the discovery of X-rays in December 1895 after seven weeks of assiduous work during which he had studied the properties of this new type of radiation able to go through screens of notable thickness. He named them X-rays to underline the fact that their nature was unknown. The news of this discovery immediately aroused an immense interest in the public and also initiated intense research in several directions. Physicians and physicists began as early as January 1896 to use X-rays on patients to investigate the skeleton and subsequently the lung and other organs. This was the birth or radiology. Rapidly they observed skin erythema, which led to the idea of using X-rays against a variety of lesions. In June 1896 the first patient was treated by radiotherapy. J.J. Thomson (Cambridge, U.K.) showed that X-rays were able to ionize gaz and the study of this phenomenon led to the discovery of electrons in 1897. In order to understand the emission of X-rays, H. Becquerel (Paris) investigated the role of the phosphorescence of the glass of the tube and while doing so discovered radioactivity in March 1896. X-rays and radioactivity were at the origin of the scientific revolution at the end of the 19th and the beginning of the 20th centuries. Research on radioactive materials demonstrated the existence of atoms which had been till then only a convenient hypothesis for explaining chemical reactions, but whose reality was considered as dubious by most physicists. Moreover, interaction of particles emitted by radionuclides and atoms enabled first the study of the structure of the atom and subsequently its nucleus. Matter, elements which were thought to be immutable were found to be transmutable, and eventually to disintegrate. The origin of the energy transferred to the radiation which was emitted appeared as a mystery and in order to explain it the physicist had to accept that matter could convert energy. In 1903 Einstein established the equivalence between matter and energy. Matter, energy, electricity, light which were formerly considered as continuous quantities were found to be discrete: there are particles of matter (elementary particles), energy (quanta, Planck 1905), electricity (electron), light (photons). Radioactive decay, particle interactions imposed a probabilistic physics which progressively replaced classic deterministic physics. Radioactivity can be used as a clock to measure time in the universe. Datations were made for fossils, art masterpieces and also for the earth, the solar system and universe. X-rays diffraction proved to be a powerful tool for studying crystals and molecules, in particular protein, and in 1953 enabled to demonstrate the DNA double helix. Hence X-rays and radioactivity originated a revolution in physics and science and in the vision of nature. The imperceptible and yet so powerful rays demonstrated the deficiencies of our senses. Mathematical entities and instrumentation must complement our sensations. The huge increment in our knowledge is accompanied by a divorce between the scientist and the layman who now often has great difficulties understanding new concepts not only in physics but also in biology.

    Hermann Abich was born in 1806 in Berlin and died in 1886 in Graz. He grew up in a wealthy family which had friendly relations with famous scientists like Alexander von Humboldt, Leopold von Buch or Carl Ritter. After his studies in Heidelberg and Berlin he turned to extended fieldwork at the volcanoes of Italy. In 1833 1834 he published excellent petrological/chemical results and got soon a good scientific reputation. Thus he was nominated as Professor for Geology and Mineralogy of the prestigious Russian University in Dorpat (now Tartu, Esthonia) in 1842. In 1844 he was sent to Armenia by the Russian authorities. For the next three decades his fieldwork with about 190 publications was concentrated on the Great and Lesser Caucasus. This was a period of Russian expansion to the South with long-lasting regional fights. But he enjoyed the support of powerful governors. He was an indefatigable and enthusiastic explorer and a precise observer and designer. His interests covered many fields: morphology, glaciology, structural geology, volcanology with Thermal Springs, mineral resources from hydrocarbons, coal, salt to ores, stratigraphy and paleontology as a base for geological maps. But he also gave advice for practical problems, and he was active in meteorology, botany and archaeology. Alltogether he became “the Father of Caucasus Geology”. The following sketch stresses only on three aspects of his activities. He was one of the first pioneers in hydrocarbon exploration, especially around the anticlines with the mud volcanoes near Baku. In many respects, however, his fundamental ideas were erronous. He explained the structure of the Great Caucasus by the traditional theories of Leopold von Buch and Elie de Beaumont. The Caucasus anticline “was elevated by forces acting from beneath”. Following them he tried to discover regularities in the strike of mountain chains. Similarily he treated volcanism like Alexander von Humboldt and Leopold von Buch with their two groups of phenomena: voluminous, mostly basaltic “elevation craters” versus isolated, mostly trachytic and relatively small cones of “true volcanoes”. In spite of the isolation of the Caucasus region he had cultivated continuously contacts with leading geologists in Europe and was honoured by many institutions. He left Russia in 1876 for Vienna planning to write there the final monograph volumes about his investigations but he died before he could complete them.

    The X-ray telescope eROSITA is the main instrument besides the Russian ART-XC on the Spektrum-Rontgen-Gamma mission. Starting from 2014, an all-sky survey will be performed in the range between 0.3-10keV, followed by pointed observations. The main objective of thismission is the detection of 100 0000 galaxy clusters in order to constrain cosmological parameters, amongst others the density distribution and evolution of dark energy. Due to the minimum lifetime of seven years the thermal control system has to be completely passive without any consumables. With the ideal operational temperature of the CCD cameras being between 173K and 183K, this requires a very effective heat rejection system, consisting of a complex heat pipe system and a good thermal insulation. Simultaneously, a very sensitive temperature control via variable conductance heat pipes is implemented. For special outgassing requirements at the betinning of the mission these heat pipes are not working after launch but can be switched on any time. On the other hand the mirror moduules have to be tempered at room temperature and more than 200W of the electronics have to be dissipated without affecting the surrounding components or the satellite structure. The thermal control system has to be able to keep up the required temperature range and has to guarantee the optimum working conditions for all parts of the instrument. Calculations and verification tests validated the thermal concept.

  14. Early victims of X-rays: a tribute and current perception

    X-rays were discovered in 1895 and since then much has been written about Wilhelm Roentgen and the events surrounding the discovery. However, there have been only scattered references in the literature about the early workers who dedicated their life, and death, to X-rays. Radiology has come of age since then. Large exposure times have been reduced to milliseconds and there has been a change from analogue to digital. The advent of new and rapidly developing modalities and the ubiquitous presence of cone beam CT (CBCT) highlight the need to remember the early victims of X-rays, especially with the lack of universal guidelines for taking a CBCT scan. The aim of this article is to alert the oral radiologist to exposing patients irrespective of need, and to pay respect to the victims on the 116th anniversary of the discovery of X-rays.

    Radiation has been a source of fascination and concern ever since Wilhelm Konrad Röntgen discovered X-rays on 8 November 1895. Over the years, health workers as well as the public have been concerned about medical uses of X-rays, the presence of radon in buildings, radioactive waste from nuclear power stations, fallout from nuclear test explosions, radioactive consumer products, microwave ovens, and many other sources of radiation. Most recently, the tragic accident at the Chernobyl nuclear power station in the USSR, and the subsequent contamination over most of Europe, has again wakened interest and concern and also reminded us about a number of misconceptions about radiation. This article describes the essentials about radiation (especially ionizing radiation) and its health effects. PMID:3496982

Primal therapy and Orgon therapy are two different forms of the "New Body Therapies" group. The authors disagree with their views of the physiological nature of Pain (A. Janov) and blokked orgon, the "function of the orgasm" and "orgastic potency", concepts that were considered by Reich to be his most important. Possible reasons for the discrepancies are given.

    For the last three years our Institute has been using a system based on a microcomputer for archiving scientifically interesting findings. This computer processes data obtained via computed tomography, sonography and angiography. Besides the coding of examination findings the system also enables compilation of efficiency statistics data. The system can be extended with comparatively little effort for processing MR data as well. Coding is not effected, as in most of the generally used systems, according to diagnosis, but according to the pathological change that can be detected via x-ray film. This prevents erroneous coding due to erroneous evaluation of the finding in question. The examinations can be stored immediately without waiting for verification. Search for defined findings is effected via screen where a search profile is set up interactively. Due to the hierarchic structure of code allocation it is possible to call for more or less detailed findings from the stored data. PMID:3533392

    Keilhack reported his impressions from his participation at the International Geological Congress in Russia in 1897 in several consecutive articles. In the more than 100 years since that time, a lot has changed. Apart from the totally different style of scientific presentations, with almost no illustrations, except maps, being shown during a talk, field trips were also a very special event, involving huge amounts of logistics. More than 200 people were transported to very remote areas of the European part of Russia. As well as organizing transportation by coaches and horses, places to stay overnight had to be found in large numbers and special regulations had to be issued by the government to allow access to various outcrops. Keilhacks visit of the oil-producing sites around Baku are of special interest, since they belonged obviously to the most productive ones on the globe at that time.

    2013-04-01

    Iron is not only the most abundant element in the Earth, but it is also the only major element with multiple electronic configurations (oxidation and spin state). The loss of a single electron or a change in the distribution of electrons between orbital states may appear minor at the atomic scale, but at the macroscopic level the effects can be profound. The oxidation state of iron varies through the mantle, from predominantly Fe2+ in the upper mantle and transition zone to roughly 50% Fe3+ in the lower mantle due to the strong affinity of (Mg,Fe)(Si,Al)O3 perovskite for Fe3+, and spin crossover transitions have been discovered to occur in both of the dominant lower mantle phases. This presentation will examine the effect of both oxidation state and spin state of iron on the physical and chemical properties of the mantle, as well as on dynamic processes that occur within our planet.

    Deans, Stanley R.

    2000-11-01

    The first medical images produced using x-rays appeared less than a year after the discovery of x-rays by Wilhelm Roentgen in 1895. For over a century x-ray projection radiography has been and continues to be the most widely used diagnostic imaging modality. For over seventy years mathematics and computational methods were used in a general way for image processing and analysis. The really challenging mathematical and computational problems did not emerge until the 1970s with the beginning of computed tomography (CT) to produce images popularly known as CAT (computer-assisted tomography) scans. This was followed rapidly by positron-emission tomography (PET) and single photon emission computed tomography (SPECT). Magnetic resonance imaging (MRI) emerged in the 1980s and is in many ways the most informative medical imaging methodology. Computer-based mathematical methods are fundamental to the success of these imaging modalities, and are increasingly important in several other novel imaging techniques. The technologies involved in each modality are competely different, have varying diagnostic value, and are described by different fundamental equations. The common underlying theme is that of the reconstruction of important characteristics of medical interest from indirect measurements. Several of these methodologies for visualizing internal body anatomy and function will be discussed and related to the evolution of computational capabilities. This brings out aspects of these biomedical imaging technologies where a deeper understanding is needed, and to frontiers where future advances are likely to come from continued research in physics jointly with the mathematical sciences.

    Medical imaging has learnt itself well into modern medicine and revolutionized medical industry in the last 30 years. Stemming from the discovery of X-ray by Nobel laureate Wilhelm Roentgen, radiology was born, leading to the creation of large quantities of digital images as opposed to film-based medium. While this rich supply of images provides immeasurable information that would otherwise not be possible to obtain, medical images pose great challenges in archiving them safe from corrupted, lost and misuse, retrievable from databases of huge sizes with varying forms of metadata, and reusable when new tools for data mining and new media for data storing become available. This paper provides a summative account on the creation of medical imaging tomography, the development of image archiving systems and the innovation from the existing acquired image data pools. The focus of this paper is on content-based image retrieval (CBIR), in particular, for 3D images, which is exemplified by our developed online e-learning system, MIRAGE, home to a repository of medical images with variety of domains and different dimensions. In terms of novelties, the facilities of CBIR for 3D images coupled with image annotation in a fully automatic fashion have been developed and implemented in the system, resonating with future versatile, flexible and sustainable medical image databases that can reap new innovations.

    Fritz Reiche (1883-1969) was a distinguished theoretical physicist, a student and colleague of Wilhelm Roentgen, Max Planck, Fritz Haber, Rudolf Ladenburg, James Franck, Max Born, Max von Laue and other early luminaries. He was coauthor of the famous Thomas-Reiche-Kuhn sum rule, and author of the seminal book The Quantum Theory, first published in 1920. He was one of the last Jewish physicists to leave Germany during the Nazi period, in 1941. In his book "Heisenberg's War" Thomas Powers relates that Reiche bore news of German work on nuclear fission, in a message from Friedrich Houtermans to Wigner and others in Princeton, where Reiche lived in Einstein's home during the summer of 1941. Reiche's son Hans later claimed that this incident played a significant role in convincing Einstein to write that letter to President Roosevelt. In this talk I will relate the difficulties Reiche experienced, first in leaving Germany and then in reestablishing his physics career in the US. He finally obtained an adjunct position at NYU where he served until his retirement. The role played by the renowned Emergency Committee in Aid of Displaced Foreign Scholars will be discussed. The particular role played by Ladenburg, who was instrumental in obtaining a small grant for Reiche permitting him to obtain a US visa, in helping many physicists leave Nazi Germany and occupied countries, will also be described.

    Within modern medicine at the beginning of 21st century, we are witnessing a revolutionary development of the invasive diagnostics and therapy of cardiovascular system diseases. With the discovery of X-rays at the end of 19th century by Wilhelm Roentgen, it is appropriate to reflect on the gifted individuals whose efforts drastically altered radiology and cardiology. The early techniques used in peripheral percutaneous transluminal angioplasty form the basis for subsequent percutaneous intervention both in the peripheral and coronary arteries and are largely the contribution of Charles Dotter. The main goal of his work was the use of catheters for diagnosis and treatment in an attempt to replace the scalpel. He was 20 years ahead of his time, especially with percutaneous transluminal angioplasty. The first percutaneous transluminal angioplasty marked a new era in the treatment of peripheral atherosclerotic lesions. This practical genius dedicated his considerable energy to the belief that there is always a better way to treat disease. His personal contributions to clinical medicine, research, and teaching have saved millions of limbs and lives all over the world. European physicians, who were more open to unproven techniques, almost immediately embraced percutaneous transluminal angioplasty. Without the contribution and help of his colleagues, Forssmann, Sones and Gruntzig, all of them pioneers, nothing would be done.They were all ahead of there time and opened completely new chapter in medicine.

    This article follows the career of the Brazilian physician Henrique da Rocha Lima, one of the first to join the group of young researchers working at the Instituto Soroterápico de Manguinhos (Instituto Oswaldo Cruz). It describes his first voyage to Germany where he specialized in microbiology and pathological anatomy, training that shaped his subsequent professional identity. The tensions and dilemmas experienced by Rocha Lima provide an insight into what it meant to dedicate oneself to a scientific career in Brazil at the start of the twentieth century. They also reveal the importance of the relations with the German-speaking world for the experimental medicine that became established under the leadership of Oswaldo Cruz. PMID:23559048

  11. Overview of the Chandra X-Ray Observatory Facility

    NASA Technical Reports Server (NTRS)

    Weisskopf, M. C.; Six, N. Frank (Technical Monitor)

    2002-01-01

    The Chandra X-Ray Observatory (originally called the Advanced X-Ray Astrophysics Facility - AXAF) is the X-Ray component of NASA's "Great Observatory" Program. Chandra is a NASA facility that provides scientific data to the international astronomical community in response to scientific proposals for its use. The Observatory is the product of the efforts of many organizations in the United States and Europe. The Great Observatories also include the Hubble Space Telescope for space-based observations of astronomical objects primarily in the visible portion of the electromagnetic spectrum, the now defunct Compton Gamma- Ray Observatory that was designed to observe gamma-ray emission from astronomical objects, and the soon-to-be-launched Space Infrared Telescope Facility (SIRTF). The Chandra X-Ray Observatory (hereafter CXO) is sensitive to X-rays in the energy range from below 0.1 to above 10.0 keV corresponding to wavelengths from 12 to 0.12 nanometers. The relationship among the various parts of the electromagnetic spectrum, sorted by characteristic temperature and the corresponding wavelength, is illustrated. The German physicist Wilhelm Roentgen discovered what he thought was a new form of radiation in 1895. He called it X-radiation to summarize its properties. The radiation had the ability to pass through many materials that easily absorb visible light and to free electrons from atoms. We now know that X-rays are nothing more than light (electromagnetic radiation) but at high energies. Light has been given many names: radio waves, microwaves, infrared, visible, ultraviolet, X-ray and gamma radiation are all different forms. Radio waves are composed of low energy particles of light (photons). Optical photons - the only photons perceived by the human eye - are a million times more energetic than the typical radio photon, whereas the energies of X-ray photons range from hundreds to thousands of times higher than that of optical photons. Very low temperature systems (hundreds of degrees below zero Celsius) produce low energy radio and microwave photons, whereas cool bodies like our own (about 30 degrees Celsius) produce infrared radiation. Very high temperatures (millions of degrees Celsius) are one way of producing X-rays.

    The X-ray astronomy group at the Marshall Space Flight Center (MSFC) is developing electroformed nickel/cobalt x-ray optics for suborbital and orbital experiments. Suborbital instruments include the Focusing X-ray Solar Imager (FOXSI) and Micro-X sounding rocket experiments and the HEROES balloon payload. Our current orbital program is the fabrication of mirror modules for the Astronomical Roentgen Telescope (ART) to be launched on board the Russian-German Spectrum Roentgen Gamma Mission (SRG). A second component of our work is the development of fabrication techniques and optical metrology to improve the angular resolution of thin-shell optics to the arcsecond-level.

    The Astronomical Roentgen Telescope (ART) instrument is a hard-x-ray instrument with energy response up to 30 keV that is to be launched on board of the Spectrum Roentgen Gamma (SRG) Mission. The instrument consists of seven identical mirror modules coupled with seven CdTe strip focal-plane detectors. The mirror modules are being developed at the Marshall Space Flight Center (MSFC.) Each module has approximately 65 sq. cm effective area and an on-axis angular resolution of 30 arcseconds half power diameter (HPD) at 8 keV. The current status of the mirror module development and testing will be presented.

    The Spectrum-Röntgen-Gamma (SRG) mission is a Russian-lead X-ray astrophysical observatory that carries two co-aligned X-ray telescope systems. The primary instrument is the German-led extended ROentgen Survey with an Imaging Telescope Array (eROSITA), a 7-module X-ray telescope system that covers the energy range from 0.2-12 keV. The complementary instrument is the Astronomical Roentgen Telescope -- X-ray Concentrator (ART-XC or ART), a 7-module Xray telescope system that provides higher energy coverage, up to 30 keV.

    SciTech Connect

    1995-10-01

    The vision of the APS sprang from prospective users, whose unflagging support the project has enjoyed throughout the decade it has taken to make this facility a reality. Perhaps the most extraordinary aspect of synchrotron radiation research, is the extensive and diverse scientific makeup of the user community. From this primordial soup of scientists exchanging ideas and information, come the collaborative and interdisciplinary accomplishments that no individual alone could produce. So, unlike the solitary Roentgen, scientists are engaged in a collective and dynamic enterprise with the potential to see and understand the structures of the most complex materials that nature or man can produce--and which underlie virtually all modern technologies. This booklet provides scientists and laymen alike with a sense of both the extraordinary history of x-rays and the knowledge they have produced, as well as the potential for future discovery contained in the APS--a source a million million times brighter than the Roentgen tube.

    The enhanced hard X-ray sensitivity provided by the Astronomical Roentgen Telescope to the Spectrum Roentgen Gamma mission facilitates the detection of heavily obscured and other hard-spectrum cosmic X-ray sources. The SRG all-sky survey will obtain large, statistically-well-defined samples of active galactic nuclei (AGN) including a significant population of local heavily-obscured AGN. In anticipation of the SRG all-sky survey, we investigate the prospects for refining the bright end of the AGN luminosity function and determination of the local black hole mass function and comparing the spatial distribution of AGN with large-scale structure defined by galaxy clusters and groups. Particular emphasis is placed on studies of the deep survey Ecliptic Pole regions.

    Roentgen signs, subperiosteal, endosteal, and trabecular bone growth are evaluated in turkeys fed phosphorus at the 0.5, 0.56, 0.68, 0.90, and 2.70 percent levels. Calcium levels of 0.30, 0.40, 0.60, 1.2, and 3.60 percent were also tested. Vitamin D levels of 0, 100, 300, 900 and 27,000 I.U. per day were likewise evaluated. Roentgen signs, bone mineral as measured by T-125 gamma ray absorption, and bone mineral growth patterns as shown by radiograph area projection are correlated with calcium, phosphorus, and vitamin D feeding levels. Differences in bone growth at the various feeding levels were observed which were not reflected by differences in other studied parameters.

Suborbital instruments include the Focusing X-ray Solar Imager (FOXSI) and Micro-X sounding rocket experiments and the HERO balloon payload. Our current orbital program is the fabrication of a series of mirror modules for the Astronomical Roentgen Telescope (ART) to be launched on board the Russian-German Spectrum Roentgen Gamma Mission (SRG.) The details and status of these various programs are presented. A second component of our work is the development of fabrication techniques and optical metrology to improve the angular resolution of thin shell optics to the arcsecond-level. The status of these x-ray optics technology developments is also presented.

  17. Exposure Range For Cine Radiographic Procedures

    NASA Astrophysics Data System (ADS)

    Moore, Robert J.

    1980-08-01

    Based on the author's experience, state-of-the-art cine radiographic equipment of the type used in modern cardiovascular laboratories for selective coronary arteriography must perform at well-defined levels to produce cine images with acceptable quantum mottle, contrast, and detail, as judged by consensus of across section of American cardiologists/radiologists experienced in viewing such images. Accordingly, a "standard" undertable state-of-the-art cine radiographic imaging system is postulated to answer the question of what patient exposure range is necessary to obtain cine images of acceptable quality. It is shown that such a standard system would be expected to produce a 'tabletop exposure of about 25 milliRoentgens per frame for the "standard" adult patient, plus-or-minus 33% for accept-able variation of system parameters. This means that for cine radiography at 60 frames per second (30 frames per second) the exposure rate range based on this model is 60 to 120 Roentgens per minute (30 to 60 Roentgens per minute). The author contends that studies at exposure levels below these will yield cine images of questionable diagnostic value; studies at exposure levels above these may yield cine images of excellent visual quality but having little additional diagnostic value, at the expense of added patient/personnel radiation exposure and added x-ray tube heat loading.

    2005-01-01

    Wilhelm Reich's technical emphasis on the "systematic analysis of defenses" was controversial even before 1933. His main opponent in this field was Reik who expressed his criticism several times from 1932 to 1935. For Reik, the analytical process was essentially open, dependent on surprise. Fenichel, Reich's ally, defended a "scientific" approach, as opposed to "intuition", but later adopted a mediatory position. PMID:17152763

    In this paper we will demonstrate how powerful "Bildung" is as a tool in modern university teaching. The concept of "Bildung" was originally introduced by the German philosopher Immanuel Kant (Kant 1787, 1798, 1804) and the Prussian lawyer and politician Wilhelm von Humboldt (Humboldt 1792, Bohlin 2008). From 1810 "Bildung" was a key concept in…

  3. The International Relations of the Struves

    NASA Astrophysics Data System (ADS)

    Dick, W. R.

    At least 10 astronomers in 5 generations belonged to the Struve dynasty, a family having its origin in Holstein and living in Germany, Russia, the USA and other countries. The best known astronomers among them were Wilhelm (1793-1864), Otto Wilhelm (1819-1905), Hermann (1854-1920), Ludwig (1858-1920), Georg (1886-1933) and Otto Ludwig Struve (1897-1963). After a short account of the family's history, its international relations will be regarded, with emphasis on the following aspects: Nationality/citizenship, places of living and work, personal relations to other astronomers including correspondence and cooperation, travels, languages of publications. Although a comparison of the different members of the family is possible only to a certain degree due to their different role and importance in astronomy, some changes which developed over 150 years can be traced: E.g., Wilhelm Struve published in German, Latin, French, Russian and English, whereas his grandsons and great-grandsons wrote their papers mainly in one language -- German or English. Wilhelm had relatively close relations with French astronomers, whereas his great-grandson Georg was the author of verbal assaults on French scientists. Georg published also heavy criticism of the International Astronomical Union, whereas his cousin Otto Luwig later became IAU's President.

    Deutschland hat sich in den letzten Jahrzehnten den internationalen Ruf erworben, auf dem Gebiet der Technologie führend zu sein. Große, weitreichende Erfindungen sind in Deutschland gemacht worden. Viele Nobelpreise gehen nach Deutschland: Robert Bosch, Nikolaus Otto und Konrad Zuse gehören genauso zu den großen Erfindern, wie Melitta Bentz und Emmy Noether. 85 % aller Nobelpreise, die seit 1901 nach Deutschland gingen, sind in den Kategorien Chemie, Physik und Medizin vergeben worden. Allein im Jahr 2007 wurden in Deutschland fast 50.000 Patente angemeldet.

    Schlegel, E.M.

    1994-12-31

    These proceedings represent papers presented at the ROSAT Science Symposium and Data Analysis Workshop held in College Park, Maryland. The aim was to showcase the results obtained thus far using ROSAT, the Roentgen Satellite, and to provide a forum for discussion regarding the means for extracting the maximum amount of information from ROSAT data. The cosmic x-ray sources discussed, included the cataclysmic variables, the Algol binary systems, the dark matter, galactic clusters, blazars, and many others. Star formation by galaxy interactions was also discussed. There were ninety one papers presented at the conference and none of these have been abstracted for the Energy Science and Technology database. (AIP)

    We review Galilean Electromagnetism since the 1973 seminal paper of Jean-Marc Lévy-Leblond and Michel Le Bellac and we explain for the first time all the historical experiments of Rowland, Vasilescu Karpen, Roentgen, Eichenwald, Wilson, Wilson and Wilson, which were previously interpreted in a Special Relativistic framework by showing the uselessness of the latter for setups involving slow motions of a part of the apparatus. Galilean Electromagnetism is not an alternative to Special Relavity but is precisely its low-velocity limit in Classical Electromagnetism.

    X-ray surveys are well suited to detect, identify and study young stars based on their high levels of magnetic activity and thus X-ray brightness. The eROSITA instrument onboard the Spectrum-Roentgen-Gamma (SRG) satellite will perform an X-ray all-sky survey that surpasses existing data by a sensitivity increase of more than an order of magnitude. The 4 yr survey is expected to detect more than half a million stars and stellar systems in X-rays.

    A soft X-ray image of the moon obtained by the Roentgen Observatory Satellite ROSAT clearly shows a sunlit crescent, demonstrating that the moon's X-ray luminosity arises from backscattering of solar X-rays. The moon's optically dark side is also X-ray dark, and casts a distinct shadow on the diffuse cosmic X-ray background. Unexpectedly, the dark side seems to emit X-rays at a level about one percent of that of the bright side; this emission very probably results from energetic solar-wind electrons striking the moon's surface.

  12. A note on the history of the Norwegian Psychoanalytic Society from 1933 to 1945.

    Anthi, Per; Haugsgjerd, Svein

    2013-08-01

    The Norwegian analysts, who were trained in Berlin before 1933, were drawn into a struggle against fascism, informed by politically leftist analysts who worked at the Berlin Institute. The Norwegian group, including the analysts Wilhelm Reich and Otto Fenichel, were committed to Marxist or social democratic ideologies in order to fight down fascism and Nazism. They were a source of inspiration but also of conflict. After the war the leadership of the IPA was sceptical about the Norwegian group because of its former connections with Die Linke, as well as its relations with Wilhelm Reich. This paper in part considers the courageous efforts of Nic Waal, whom Ernest Jones used as a delegate and courier to solve problems for the IPA and who was unjustly treated after the war.

  13. On the potential energy in a gravitationally bound two-body system with arbitrary mass distribution

    K. Wilhelm; B. N. Dwivedi

    2015-02-12

    The potential energy problem in a gravitationally bound two-body system has recently been studied in the framework of a proposed impact model of gravitation (Wilhelm and Dwivedi 2015). The result was applied to the free fall of the so-called Mintrop--Ball in G\\"ottingen with the implicit assumption that the mass distribution of the system is extremely unbalanced. An attempt to generalize the study to arbitrary mass distributions indicated a conflict with the energy conservation law in a closed system. This necessitated us to reconsider an earlier assumption made in selecting a specific process out of two options (Wilhelm et al. 2013). With the result obtained here we can now make an educated selection and reverse our choice. The consequences are presented and discussed in detail for several processes. Energy and momentum conservation could now be demonstrated in all cases.

  14. Helmholtz and the psychophysiology of time.

    PubMed

    Debru, C

    2001-09-01

    After having measured the velocity of the nervous impulse in the 1850s, Helmholtz began doing research on the temporal dimensions of visual perception. Experiments dealing with the velocity of propagation in nerves (as well as with aspects of perception) were carried out occasionally for some fifteen years until their final publication in 1871. Although the temporal dimension of perception seems to have interested Helmholtz less than problems of geometry and space, his experiments on the time of perception were technically rather subtle and seminal, especially compared with experiments performed by his contemporaries, such as Sigmund Exner, William James, Rudolf Hermann Lotze, Ernst Mach, Wilhelm Volkmann, and Wilhelm Wundt. Helmholtz's conception of the temporal aspects of perception reflects the continuity that holds between psychophysiological research and the Kantian philosophical background. PMID:12068897

    The role that Otto Hahn (1879 1968) played in the discovery of nuclear fission and whether Lise Meitner (1878 1968) should have shared the Nobel Prize for that discovery have been subjects of earlier studies, but there is more to the story. I examine what Hahn and the scientists in his Kaiser Wilhelm Institute for Chemistry in Berlin-Dahlem did during the Third Reich, in particular, the significant contributions they made to the German uranium project during the Second World War. I then use this as a basis for judging Hahn’s postwar apologia as the last president of the Kaiser Wilhelm Society and first president of its successor, the Max Planck Society.

  16. The Politics of Memory: Otto Hahn and the Third Reich

    NASA Astrophysics Data System (ADS)

    Sime, Ruth Lewin

    2006-03-01

    As President of the Kaiser Wilhelm Society and its successor, the Max Planck Society, from 1946 until 1960, Otto Hahn (1879 1968) sought to portray science under the Third Reich as a purely intellectual endeavor untainted by National Socialism. I outline Hahn’s activities from 1933 into the postwar years, focusing on the contrast between his personal stance during the National Socialist period, when he distinguished himself as an upright non-Nazi, and his postwar attitude, which was characterized by suppression and denial of Germany’s recent past. Particular examples include Hahn’s efforts to help Jewish friends; his testimony for colleagues involved in denazification and on trial in Nuremberg; his postwar relationships with émigré colleagues, including Lise Meitner; and his misrepresentation of his wartime work in the Kaiser Wilhelm Institute for Chemistry.

  17. The role of tone sensation and musical stimuli in early experimental psychology.

    PubMed

    Klempe, Sven Hroar

    2011-01-01

    In this article, the role of music in early experimental psychology is examined. Initially, the research of Wilhelm Wundt is considered, as tone sensation and musical elements appear as dominant factors in much of his work. It is hypothesized that this approach was motivated by an understanding of psychology that dates back to Christian Wolff 's focus on sensation in his empirical psychology of 1732. Wolff, however, had built his systematization of psychology on Gottfried Wilhelm von Leibniz, who combined perception with mathematics,and referred to music as the area in which sensation is united with numerical exactitude. Immanuel Kant refused to accept empirical psychology as a science, whereas Johann Friedrich Herbart reintroduced the scientific basis of empirical psychology by, among other things, referring to music.

    NASA Astrophysics Data System (ADS)

    Dick, Wolfgang R.; Duerbeck, H. W.; Hamel, Jürgen

    The contributions deal with astronomical events of the past 1000 years. We elucidate the person of the single European observer of the supernova of 1006, and the views of Christoph Scheiner and Otto von Guericke on the structure and substance of the cosmos. A study of the development of the Copernican and the cosmological principles conclude this group of themes. Biographical investigations were carried out on the clockmaker Nikolaus Lilienfeld, the astronomers Johann Wurzelbau, Friedrich Wilhelm Toennies and Boris Karpov as well as the “panbabylonist” Alfred Jeremias. Astronomers can be active also in poetry and fiction. This is shown in the studies of Johann Leonard Rost and Friedrich Wilhelm Bessel. Finally, Johannes Hevelius' Observatory in Danzig/Gdansk, destroyed by a fire in 1679, is reconstructed by means of printed sources, old maps and photographs. The book concludes by short communications, obituaries and book reviews.

  19. Anomalous Earth flybys of spacecraft

    NASA Astrophysics Data System (ADS)

    Wilhelm, Klaus; Dwivedi, Bhola N.

    2015-07-01

    A small deviation from the potential is expected for the gravitational interaction of extended bodies. It is explained as a consequence of a recently proposed gravitational impact model (Wilhelm et al. in Astrophys. Space Sci. 343:135-144, 2013) and has been applied to anomalous perihelion advances by Wilhelm and Dwivedi (New Astron. 31:51-55, 2014). The effect—an offset of the effective gravitational centre from the geometric centre of a spherical symmetric body—might also be responsible for the observed anomalous orbital energy gains and speed increases during Earth flybys of several spacecraft. However, close flybys would require detailed considerations of the orbit geometry. In this study, an attempt is made to explain the anomalous Earth flybys of the Galileo, NEAR Shoemaker and Rosetta spacecraft.

  4. Rebuttal to the comment by Malhotra and Strom on "Constraints on the source of lunar cataclysm impactors"

    2011-11-01

    ?uk et al. (?uk, M. Gladman, B.J., Stewart, S.T. [2010]. Icarus 207 590-594) concluded that the the lunar cataclysm (late heavy bombardment) was recorded in lunar Imbrian era craters, and that their size distribution is different from that of main belt asteroids (which may have been the dominant pre-Imbrian impactors). This result would likely preclude the asteroid belt as the direct source of lunar cataclysm impactors. Malhotra and Strom (Malhotra, R., Strom, R.G. [2011]. Icarus) maintain that the lunar impactor population in the Imbrian era was the same as in Nectarian and pre-Nectarian periods, and this population had a size distribution identical to that of main belt asteroids. In support of this claim, they present an Imbrian size distribution made from two data sets published by Wilhelms et al. (Wilhelms, D.E., Oberbeck, V.R., Aggarwal, H.R. [1978]. Proc. Lunar Sci. Conf. 9, 3735-3762). However, these two data sets cannot be simply combined as they represent areas of different ages and therefore crater densities. Malhotra and Strom (Malhotra, R., Strom, R.G. [2011]. Icarus) differ with the main conclusion of Wilhelms et al. (Wilhelms, D.E., Oberbeck, V.R., Aggarwal, H.R. [1978]. Proc. Lunar Sci. Conf. 9, 3735-3762) that the Nectarian and Imbrian crater size distributions were different. We conclude that the available data indicate that the lunar Imbrian-era impactors had a different size distribution from the older ones, with the Imbrian impactor distribution being significantly richer in small impactors than that of older lunar impactors or current main-belt asteroids.

    The second law of thermodynamics, which states that the entropy of an isolated macroscopic system can increase but will not decrease, is a cornerstone of modern physics. Ludwig Boltzmann argued that the second law arises from the motion of the atoms that compose the system. Boltzmann's statistical mechanics provides deep insight into the functioning of the second law and also provided evidence for the existence of atoms at a time when many scientists (like Ernst Mach and Wilhelm Ostwald) were skeptical.

The papers published here follow a natural progression through the following topics: helicity and related invariants of magnetic fields in ideal MHD; relaxation under topological constraints; lower bounds on magnetic energy; current and vortex filaments; applications in the solar corona, tokamak plasmas, and cyclone dynamics; higher-order invariants; topology of curves and surfaces, and energy measures; tight knots; applications to Bose-Einstein condensates, QCD, and cosmic superstring theory. Some of the papers span more than one of these areas. We owe a great debt of gratitude to Konrad Bajer, who was one of the guiding spirits behind the whole Newton Institute program, and who took particular responsibility for the Satellite Workshop at ICMS, Edinburgh. Konrad fell seriously ill in June 2014, having completed much of the editorial work for these Proceedings. Following an operation at the end of July, he remained optimistic of a complete recovery, but sadly this was not to be, and he died from a particularly malignant form of cancer on 29th August. The funeral was held in Warsaw on 5th September. Konrad's warmth of personality and generosity of spirit will be remembered by all who participated in these workshops and in the wider Newton Institute program. The Isaac Newton Institute provided an ideal environment for informal interactions before and after both these workshops. We wish to express our thanks to the Director and staff of the Institute for their tireless efforts to ensure the success of the whole program; also to the staff of ICMS, Edinburgh, for their expert hosting of the satellite workshop.

    eROSITA (extended ROentgen Survey with an Imaging Telescope Array) is the core instrument on the Russian/German Spektrum-Roentgen-Gamma (SRG) mission which is current scheduled for launch in 2016. In the soft band (0.5-2 keV), the deep All-sky survey will be 30 times more sensitive than the previous ROSAT All-sky survey, while the first ever true all-sky survey will be mapped in the hard band (2-8 keV).The design driving science is the detection of large samples of galaxy clusters to redshifts z > 1, in order to study the large scale structure in the Universe and test cosmological models including Dark Energy. In addition, eROSITA is expected to yield a sample of around 3 million active galactic nuclei, which is bound to revolutionize our view of the evolution of supermassive black holes and their impact on the process of structure formation in the Universe.I will review the main characteristics of eROSITA All-sky survey, with an eye also on the planned spectroscopic follow-up of the sources with SDSS-IV/SPIDERS and ESO/4MOST.

    Computerized digitization and processing of roentgen video images recorded at a rate of 50 per second was tested in intravenous angiocardiography in normal pigs weighing 15 to 20 kg. Roentgen video images were recorded in the 4-chamber view obtained by 30-35 degrees caudocranial angulation of the x-ray tube and 50-60 degrees LAO obliquity in the pig. Significant contrast enhancement was obtained through ECG-gated background subtraction and rescaling after integration of multiple background as well as contrast images. Occasionally, histogram equalization was used to further enhance contrast. To study temporal changes in cardiac motion, time parameter extraction or functional imaging was applied as well. The left and right heart were well visualized after intravenous injection of 1/3-1 cc. 76% Urografin per kg. bodyweight. Special purpose processing like subtraction of the end systolic phase from the end diastolic in the left and right ventricles as well as subtraction of the right ventricular phase from the left ventricular phase was also performed. If the left ventricular end systolic phase was subtracted from the end diastolic, most of the left atrium was also subtracted whereby the left ventricle was seen without continuity or superimposition of the left atrium. Experimentally generated ventricular and atrial septal defects as well as patent ductus arteriosus could be detected using the described technique. The results of the animal experiments became the basis for subsequent applications in children with congenital heart disease.

    The purpose of this study was to analyse the cost structure of radiological procedures in the intermediary referral hospitals and general practice and to develop a cost accounting system for radiological examinations that takes into consideration all relevant cost factors and is suitable for management of radiology departments and regional planning of radiological resources. The material comprised 174,560 basic radiological examinations performed in 1991 at 5 intermediate referral hospitals and 13 public health centres in the Pirkanmaa Hospital District in Finland. All radiological departments in the hospitals were managed by a specialist in radiology. The radiology departments at the public health care centres operated on a self-referral basis by general practitioners. The data were extracted from examination lists, inventories and balance sheets; parts of the data were estimated or calculated. The radiological examinations were compiled according to the type of examination and equipment used: conventional, contrast medium, ultrasound, mammography and roentgen examinations with mobile equipment. The majority of the examinations (87%) comprised conventional radiography. For cost analysis the cost items were grouped into 5 cost factors: personnel, equipment, material, real estate and administration costs. The depreciation time used was 10 years for roentgen equipment, 5 years for ultrasound equipment and 5 to 10 years for other capital goods. An annual interest rate of 10% was applied. Standard average values based on a sample at 2 hospitals were used for the examination-specific radiologist time, radiographer time and material costs. Four cost accounting versions with varying allocation of the major cost items were designed. Two-way analysis of variance of the effect of different allocation methods on the costs and cost structure of the examination groups was performed. On the basis of the cost analysis a cost accounting program containing both monetary and nonmonetary variables was developed. In it the radiologist, radiographer and examination-specific equipment costs were allocated to the examinations applying estimated cost equivalents. Some minor cost items were replaced by a general cost factor (GCF). The program is suitable for internal cost accounting of radiological departments as well as regional planning. If more accurate cost information is required, cost assignment employing the actual consumption of the resources and applying the principles of activity-based cost accounting is recommended. As an application of the cost accounting formula the average costs of the radiological examinations were calculated. In conventional radiography the average proportion of the cost factors in the total material was: personnel costs 43%, equipment costs 26%, material costs 7%, real estate costs 11%, administration and overheads 14%. The average total costs including radiologist costs in the hospitals were (FIM): conventional roentgen examinations 188, contrast medium examinations 695, ultrasound 296, mammography 315, roentgen examinations with mobile equipment 1578. The average total costs without radiologist costs in the public health centres were (FIM): conventional roentgen examinations 107, contrast medium examinations 988, ultrasound 203, mammography 557. The average currency rate of exchange in 1991 was USD 1 = FIM 4.046. The following formula is proposed for calculating the cost of a radiological examination (or a group of examinations) performed with a certain piece of equipment during a period of time (e.g. 1 year): a2/ sigma ax*ax+ b2/ sigma bx*bx+ d1/d5*dx+ e1 + [(c1+ c2) + d4 + (e2 - e3) + f5 + g1+ g2+ i]/n.

  7. Superconducting qubits on the way to a quantum processor

    2007-03-01

    Experimental research on supeconducting qubits has seen an enormous progress in recent years. About 10 years after its first theoretical proposals, experiments have demonstrated the necessary building blocks for the exploration of quantum information along several avenues: Single qubit-rotations, long coherence times, high-fidelity nondemolition readout, two-qubit interactions and gates, coupling to delocalized qubit modes. With this progress, analogies to other qubit candidates such as magnetic resonance systems, atomic, and optical systems are evident, but we also see the specific strengths of superconducting qubits play out - in situ tunable strong qubit-qubit coupling, strong coupling between qubits and the quantized electromagnetic field, strong intrinsic nonlinearity, and the possibility to fabricate large circuits. Most of these achievements will be discussed later in the session. I will give an introduction to superconducting qubits in the perspective of quantum information processing [1] accessible to outsiders in the field. I will put the different elements of the session in the perspective of an actual scalable architecture which allows for fault-tolerant quantum computation [1,2]. In order to make further progress in direction, the fidelities of quantum operations need to be improved. I will discuss the crucial topic of understanding and further supressing noise from material defects in these systems, which can influence both the phase and bit-flip error rate [3,4]. I will show, how optimal control theory can help to find fast and high-fidelity shaped pulses for superconducting qubits, even though they, other than spin 1/2 systems, have relatively close leakage levels outside the qubit manyfold [5,6]. This technique also allows to optimize pulses in the presence of telegraph noise [6]. Finally, I will describe how the strong nonlinearity of Josephson circuit can be used for the generation of single microwave photons [7] and lead to a nonlinear generalization of cavity quantum electrodynamics effects [8].[1] M.R.

  8. NOTE: Speed optimized influence matrix processing in inverse treatment planning tools

    An optimal plan in modern treatment planning tools is found through the use of an iterative optimization algorithm, which deals with a high amount of patient-related data and number of treatment parameters to be optimized. Thus, calculating a good plan is a very time-consuming process which limits the application for patients in clinics and for research activities aiming for more accuracy. A common technique to handle the vast amount of radiation dose data is the concept of the influence matrix (DIJ), which stores the dose contribution of each bixel to the patient in the main memory of the computer. This study revealed that a bottleneck for the optimization time arises from the data transfer of the dose data between the memory and the CPU. In this note, we introduce a new method which speeds up the data transportation from stored dose data to the CPU. As an example we used the DIJ approach as is implemented in our treatment planning tool KonRad, developed at the German Cancer Research Center (DKFZ) in Heidelberg. A data cycle reordering method is proposed to take the advantage of modern memory hardware. This induces a minimal eviction policy which results in a memory behaviour exhibiting a 2.6 times faster algorithm compared to the naive implementation. Although our method is described for the DIJ approach implemented in KonRad, we believe that any other planning tool which uses a similar approach to store the dose data will also benefit from the described methods.

  10. The onset of labour: an alternative theory.

    PubMed

    Jones, P

    1996-02-01

    This article, based mainly on the theories and discoveries of Wilhelm Reich (1897-1957), puts forward the bio-energetic theory of the onset of labour, which assumes it to be one of many examples of bio-energetic pulsation in the organism. It suggests that chronic muscular tension ('armouring') interferes with this spontaneous pulsation and may account for many of the difficulties experienced by women in labour. A form of psychotherapy ('orgone-therapy') based on these theories may prove helpful in childbirth education, in the non-intrusive induction of labour, and in labour itself. A research project to test this hypothesis is suggested. PMID:9439268

    The present study was motivated by results from a preliminary report documenting the impact of specific crewmembers on overall crew performance (Wilhelm & Law, 1992), and a cross-airline cross-fleet project investigating human factors behaviors of commercial aviation flightcrews (Helmreich, Butler, Whilhelm, & Lofaro, 1992). The purpose of the current investigation is to study how position-specific behaviors impact flightcrew performance, and how these position-specific behaviors differ between two airlines and two flying environments. Implications for training will also be addressed.

    A strain of Aspergillus ochraceus Wilhelm, isolated from poultry feed, produced both penicillic acid and ochratoxin A. Studies demonstrating the ability of this fungus to colonize poultry feed and produce these two mycotoxins under various temperatures and moistures indicated that the interaction was complex. The optimal temperature for conidial development did not vary with moisture, but accumulation of both toxins did. A combination of low temperature, 15 or 22 C, and low moisture favored the production of penicillic acid, whereas high temperature, 30 C, and high moisture favored the production of ochratoxin A.

  14. A structural and intertextual reading of Freud's "On Dreams".

    PubMed

    Mahlendorf, U

    2000-04-01

    By using the framework of a "quest" narrative based on literary allusions to Virgil's Aeneid and Goethe's Wilhelm Meister's Apprenticeship, Freud transformed the 500 pages of The Interpretation of Dreams into some fifty pages entitled "On Dreams." This paper elucidates the narrative means by which Freud achieved the feat of turning a highly complex, lengthy theoretical work into an engaging narrative. Its main plot, provided by a specimen dream, reveals Freud's working through of the personal and professional conflicts of his life up to 1901, and serves as a practical demonstration of and paradigm for the process of working through in psychoanalysis.

    Crownprince Frederick Wilhelm of Prussia was once the hope of the liberal movement in Germany. He embodied and lived a humanistic ideal based on the spirit of the enlightenment. Starting in January 1887 the passionate pipe smoker suffered on an unusual long hoarseness. A polyp of the vocal cord was diagnosed. Although this diagnosis seemed harmless, an odyssee was launched that made history. Rudolf Virchow-the foremost pathologist of that time-was involved in the following histological diagnosis. His role and that of the sprouting histopathology will be presented in this essay. PMID:25925224

The letter supports the earlier assumption that Johann Ernst recommended Rothmann to Landgrave Wilhelm of Hesse, as Rothmann asks for Johann Ernst's help on the matter in this new source. More importantly Rothmann refers to his attempts to make Copernicus' calculations compatible with the Ptolomean model, which demonstrates that already at this stage of his career he was working on such a compromise, and not only after being influenced by Raimarus Ursus or Tycho Brahe, as has been argued by some authors.
